Humana Inc: Form 10-K for the period ended Dec 31, 2024

General

Headquartered in Louisville, Kentucky, Humana Inc. and its subsidiaries, referred to throughout this document as “we,” “us,” “our,” the “Company” or “Humana,” is committed to putting health first – for our teammates, our customers, and our company. Through our Humana insurance services, and our CenterWell health care services, we make it easier for the millions of people we serve to achieve their best health – delivering the care and service they need, when they need it. These efforts are leading to a better quality of life for people with Medicare, Medicaid, families, individuals, military service personnel, and communities at large.

As of December 31, 2024, we had approximately 16 million members in our medical benefit plans, as well as approximately 5 million members in our specialty products. During 2024, 85% of our total premiums and services revenue were derived from contracts with the federal government, including 14% derived from our individual Medicare Advantage contracts in Florida with the Centers for Medicare and Medicaid Services, or CMS, under which we provide health insurance coverage to approximately 924,800 members as of December 31, 2024.

Humana Inc. was organized as a Delaware corporation in 1964. Our principal executive offices are located at 500 West Main Street, Louisville, Kentucky 40202, the telephone number at that address is (502) 580-1000, and our website address is www.humana.com (http://www.humana.com). We have made available free of charge through the Investor Relations section of our web site our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy statements, and, if applicable, amendments to those reports filed or furnished pursuant to Section 13(a) of the Exchange Act, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission.

This Annual Report on Form 10-K, or 2024 Form 10-K, contains both historical and forward-looking information. See Part I, Item 1A, "Risk Factors" of this Form 10-K for a description of a number of factors that may adversely affect our results or business.

Business Segments

Our two reportable segments, Insurance and CenterWell, are based on a combination of the type of health plan customer and adjacent businesses centered on well-being solutions for our health plans and other customers. Our Chief Executive Officer, the Chief Operating Decision Maker, utilizes these segment groupings and results of each segment, measured by income (loss) from operations, to assess performance and allocate resources primarily during our annual budget process and periodic forecast updates. For additional information on our business segments and segment financial information, refer to Note 18 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Our Products

Our medical and specialty insurance products allow members to access health care services primarily through our networks of health care providers with whom we have contracted. These products may vary in the degree to which members have coverage. Health maintenance organizations, or HMOs, include comprehensive managed care benefits generally through a participating network of physicians, hospitals, and other providers. Preferred provider organizations, or PPOs, provide members the freedom to choose any health care provider. However, PPOs generally require the member to pay a greater portion of the provider’s fee in the event the member chooses not to use a provider participating in the PPO’s network. Point of Service, or POS, plans combine the advantages of HMO plans with the flexibility of PPO plans. In general, POS plans allow members to choose, at the time medical services are needed, to seek care from a provider within the plan’s network or outside the network. In addition, we offer services to our health plan members as well as to third parties that promote health and wellness, including pharmacy solutions, primary care, and home solutions, as well as services and capabilities to advance population health. At the core of our strategy is our integrated care delivery model, which unites quality care, high member engagement, and sophisticated data analytics. Three core elements of the model are to improve the consumer experience by simplifying the interaction with us, engaging members in clinical programs, and offering assistance to providers in transitioning from a fee-for-service, or FFS, to a value-based arrangement. Our approach to primary, physician-directed care for our members aims to provide quality care that is consistent, integrated, cost-effective, and member-focused. The model is designed to improve health outcomes and affordability for individuals and for the health system as a whole, while offering our members a simple, seamless healthcare experience. The discussion that follows describes the products offered by each of our segments.

Our Insurance Segment Products

The Insurance segment is comprised of insurance products serving Medicare and state-based contract beneficiaries, as well as individuals and employers. The segment also includes our Pharmacy Benefit Manager, or PBM, business. These products are described in the discussion that follows.

The following table presents our premiums and services revenue for the Insurance segment by product for the year ended December 31, 2024:

(dollars in millions)

Medicare

We have participated in the Medicare program for private health plans for over 30 years and have established a national presence, offering at least one type of Medicare plan in all 50 states. We have a geographically diverse membership base that we believe provides us with greater ability to expand our network of PPO and HMO providers. We employ strategies including health assessments and clinical guidance programs such as lifestyle and fitness programs for seniors to guide Medicare beneficiaries in making cost-effective decisions with respect to their health care. We believe these strategies result in cost savings that occur from making positive behavior changes.

Medicare is a federal program that provides persons age 65 and over and some disabled persons under the age of 65 certain hospital and medical insurance benefits. CMS, an agency of the United States Department of Health and Human Services, administers the Medicare program. Hospitalization benefits are provided under Part A, without the payment of any premium, for up to 90 days per incident of illness plus a lifetime reserve aggregating 60 days. Eligible beneficiaries are required to pay an annually adjusted premium to the federal government to be eligible for physician care and other services under Part B. Beneficiaries eligible for Part A and Part B coverage under traditional fee-for-service Medicare are still required to pay out-of-pocket deductibles and coinsurance. Throughout this document this program is referred to as Medicare FFS. As an alternative to Medicare FFS, in geographic areas where a managed care organization has contracted with CMS pursuant to the Medicare Advantage program, Medicare beneficiaries may choose to receive benefits from a Medicare Advantage organization under Medicare Part C. Pursuant to Medicare Part C, Medicare Advantage organizations contract with CMS to offer Medicare Advantage plans to provide benefits at least comparable to those offered under Medicare FFS. Our Medicare Advantage, or MA, plans are discussed in the following sections. Prescription drug benefits are provided under Part D.

Individual Medicare Advantage Products

We contract with CMS under the Medicare Advantage program to provide a comprehensive array of health insurance benefits, including wellness programs, chronic care management, and care coordination, to Medicare eligible persons under HMO, PPO, Private Fee-For-Service, or PFFS, and Special Needs Plans, including Dual Eligible Special Needs, or D-SNP, plans in exchange for contractual payments received from CMS, usually a fixed payment per member per month. With each of these products, the beneficiary receives benefits in excess of Medicare FFS, typically including reduced cost sharing, enhanced prescription drug benefits, care coordination, data analysis techniques to help identify member needs, complex case management, tools to guide members in their health care decisions, care management programs, wellness and prevention programs and, in some instances, a reduced monthly Part B premium. Most Medicare Advantage plans offer the prescription drug benefit under Part D as part of the basic plan, subject to cost sharing and other limitations. Accordingly, all of the provisions of the Medicare Part D program described in connection with our stand-alone prescription drug plans in the following section also are applicable to most of our Medicare Advantage plans. Medicare Advantage plans may charge beneficiaries monthly premiums and other copayments for Medicare-covered services or for certain extra benefits. Generally, Medicare-eligible individuals enroll in one of our plan choices between October 15 and December 7 for coverage that begins on the following January 1.

Our Medicare HMO and PPO plans, which cover Medicare-eligible individuals residing in certain counties, may eliminate or reduce coinsurance or the level of deductibles on many other medical services while seeking care from participating in-network providers or in emergency situations. Except in emergency situations or as specified by the plan, most HMO plans provide no out-of-network benefits. PPO plans carry an out-of network benefit that is subject to higher member cost-sharing. In some cases, these beneficiaries are required to pay a monthly premium to the HMO or PPO plan in addition to the monthly Part B premium they are required to pay the Medicare program.

Most of our Medicare PFFS plans are network-based products with in and out of network benefits due to a requirement that Medicare Advantage organizations establish adequate provider networks, except in geographic areas that CMS determines have fewer than two network-based Medicare Advantage plans. In these areas, we offer Medicare PFFS plans that have no preferred network. Individuals in these plans pay us a monthly premium to receive typical Medicare Advantage benefits along with the freedom to choose any health care provider that accepts individuals at rates equivalent to Medicare FFS payment rates.

CMS uses a risk-adjustment model which adjusts premiums paid to Medicare Advantage, or MA, plans according to health status of covered members. The risk-adjustment model, which CMS implemented pursuant to the Balanced Budget Act of 1997 (BBA) and the Benefits Improvement and Protection Act of 2000 (BIPA), generally pays more where a plan's membership has higher expected costs. Under this model, rates paid to MA plans are based on actuarially determined bids, which include a process whereby our prospective payments are based on our estimated cost of providing standard Medicare-covered benefits to an enrollee with a "national average risk profile." That baseline payment amount is adjusted to account for certain demographic characteristics and health status of our enrolled members. Under the risk-adjustment methodology, all MA plans must collect from providers and submit the necessary diagnosis code information to CMS within prescribed deadlines. The CMS risk-adjustment model uses the diagnosis data, collected from providers, to calculate the health status-related risk-adjusted premium payment to MA plans, which CMS further adjusts for coding pattern differences between the health plans and the government fee-for-service (FFS) program. We generally rely on providers, including certain providers in our network who are our employees, to code their claim submissions with appropriate diagnoses, which we send to CMS as the basis for our health status-adjusted payment received from CMS under the actuarial risk-adjustment model. We also rely on these providers to document appropriately all medical data, including the diagnosis data submitted with claims. In addition, we conduct medical record reviews as part of our data and payment accuracy compliance efforts, to more accurately reflect diagnosis conditions under the risk adjustment model. For additional information, refer to Note 17 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" and Part I, Item 1A, "Risk Factors" of this Form 10-K.

At December 31, 2024, we provided health insurance coverage under CMS contracts to approximately 5,661,800 individual Medicare Advantage members, including approximately 924,800 members in Florida. These

Florida contracts accounted for premiums revenue of approximately $16.4 billion, which represented approximately 19% of our individual Medicare Advantage premiums revenue, or 14% of our consolidated premiums and services revenue for the year ended December 31, 2024.

Our individual Medicare Advantage products covered under Medicare Advantage contracts with CMS are renewed generally for a calendar year term unless CMS notifies us of its decision not to renew by May 1 of the calendar year in which the contract would end, or we notify CMS of our decision not to renew by the first Monday in June of the calendar year in which the contract would end. All material contracts between Humana and CMS relating to our Medicare Advantage products have been renewed for 2025, and all of our product offerings filed with CMS for 2025 have been approved.

Individual Medicare Stand-Alone Prescription Drug Products

We offer stand-alone prescription drug plans, or PDPs, under Medicare Part D, including a PDP offering co-branded with Walmart Inc., or the Humana-Walmart plan. Generally, Medicare-eligible individuals enroll in one of our plan choices between October 15 and December 7 for coverage that begins on the following January 1. Our stand-alone PDP offerings consist of plans offering basic coverage with benefits mandated by Congress, as well as plans providing enhanced coverage with varying degrees of out-of-pocket costs for premiums, deductibles, and co-insurance. Our revenues from CMS and the beneficiary are determined from our PDP bids submitted annually to CMS. These revenues also reflect the health status of the beneficiary and risk sharing provisions as more fully described in Note 2 to the audited Consolidated Financial Statements included in Item 8. – Financial Statements and Supplementary Data, titled “Receivables and Revenue Recognition.” Our stand-alone PDP contracts with CMS are renewed generally for a calendar year term unless CMS notifies us of its decision not to renew by May 1 of the calendar year in which the contract would end, or we notify CMS of our decision not to renew by the first Monday in June of the calendar year in which the contract would end. All material contracts between Humana and CMS relating to our Medicare stand-alone PDP products have been renewed for 2025, and all of our product offerings filed with CMS for 2025 have been approved.

We have administered CMS’s Limited Income Newly Eligible Transition, or LI-NET, prescription drug plan program since 2010. This program allows individuals who receive Medicare’s low-income subsidy to also receive immediate prescription drug coverage at the point of sale if they are not already enrolled in a Medicare Part D plan. CMS temporarily enrolls newly identified individuals with both Medicare and Medicaid into the LI-NET prescription drug plan program, and subsequently transitions each member into a Medicare Part D plan that may or may not be a Humana Medicare plan.

Group Medicare Advantage and Medicare Stand-Alone PDP

We offer products that enable employers that provide post-retirement health care benefits to replace Medicare wrap or Medicare supplement products with Medicare Advantage or stand-alone PDPs from Humana. These products are primarily offered as PPO plans on the same Medicare platform as individual Medicare Advantage plans. These plans offer the same types of benefits and services available to members in our individual Medicare plans discussed previously, however, group Medicare Advantage plans typically have richer benefit offerings than individual Medicare Advantage plans, including prescription drug coverage in the gap, for instance, due to the desire of many customers to closely match their pre-retirement benefit structure.

Medicare Supplement

We also offer Medicare supplement products that help pay the medical expenses that Medicare FFS does not cover, such as copayments, coinsurance and deductibles.

State-based Contracts

Through our state-based contracts, we serve members enrolled in Medicaid, a program funded by both the federal and state governments and administered by states to care for their most vulnerable populations. Within federal guidelines, states determine whom to cover, but general categories for traditional Medicaid programs include children and parents; Aged, Blind, and Disabled (ABD) individuals; and Medicaid Expansion adults. Through Medicaid Managed Long-Term Support Services (MLTSS) programs, states offer programs to deliver support services to people who receive home and community or institution-based services for long-term care.

We have contracts in multiple states to serve Medicaid-eligible members, including Florida, Kentucky, Illinois, Indiana, Louisiana, Ohio, Oklahoma, South Carolina and Wisconsin.

We also serve members who qualify for both Medicaid and Medicare, referred to as "dual eligible", through our Medicaid, Medicare Advantage, and stand-alone prescription drug plans. As the dual eligible population represents a disproportionate share of costs, Humana is participating in varied integration models designed to improve health outcomes and reduce avoidable costs.

As part of our individual Medicare Advantage products, we also offer Dual-Eligible Special Needs Plans (D-SNP). In connection with offering a D-SNP in a particular state, we are required to enter into a special coordinating contract with the applicable state Medicaid agency. To meet federal requirements that took effect in 2021, states have implemented new D-SNP requirements to strengthen Medicaid-Medicare integration requirements for D-SNPs. Some states are also moving to support the dual eligible population by linking D-SNP participation to enrollment in a plan that also participates in a state-based Medicaid program to coordinate and integrate both Medicare and Medicaid benefits.

Specialty

We sell specialty and ancillary insurance benefits consisting of dental, vision, life and disability to employer groups. In addition, we sell dental and vision specialty insurance benefits to individuals.

Commercial Fully-Insured and ASO

In February 2023, we announced our planned exit from the Employer Group Commercial Medical Products business, which includes all fully insured, self-funded and Federal Employee Health Benefit medical plans, as well as associated wellness and rewards programs. Following a strategic review, we determined the Employer Group Commercial Medical Products business was no longer positioned to sustainably meet the needs of commercial members over the long term or support our long-term strategic plans. We anticipate the exit of this line of business to be finalized in the first half of 2025.

For in-force group commercial medical customers and members, our commercial products included a broad spectrum of major medical benefits with multiple in-network coinsurance levels and annual deductible choices that employers of all sizes offered to their employees on either a fully-insured, through HMO, PPO, or POS plans, or self-funded basis. Our plans integrated clinical programs, plan designs, communication tools, and spending accounts.

Our ASO products were offered to small group and large group employers who self-insured their employee health plans. We received fees to provide administrative services which generally included the processing of claims, offering access to our provider networks and clinical programs, and responding to customer service inquiries from members of self-funded employers. These products might have included all of the same benefit and product design characteristics of our fully-insured HMO, PPO, or POS products described previously. Under ASO contracts, self-funded employers generally retained the risk of financing the costs of health benefits, with large group customers retaining a greater share and small group customers a smaller share of the cost of health benefits. All small group ASO customers and many large group ASO customers purchased stop loss insurance coverage from us to cover catastrophic claims or to limit aggregate annual costs.

Military Services

Under our TRICARE contracts with the United States Department of Defense, or DoD, we provide administrative services to arrange health care services for active-duty and retired military personnel and their dependents. We have participated in the TRICARE program since 1996 under contracts with the DoD. Under our contracts, we provide administrative services while the federal government retains all of the risk of the cost of health benefits. Accordingly, we account for revenues under the current contract net of estimated health care costs similar to an administrative services fee only agreement.

We delivered services under the T2017 East Region contract from commencement on January 1, 2018 through expiration on December 31, 2024. The T2017 East Region contract comprised 32 states and approximately 6 million TRICARE beneficiaries. In December 2022, we were awarded the next generation of TRICARE Managed Care Support Contracts, or T-5, for the updated TRICARE East Region by the Defense Health Agency of the DoD. The T-5 East Region contract commenced on January 1, 2025 and comprises 24 states, and Washington D.C., and approximately 4.6 million beneficiaries. The transition period for the T-5 contract began in January 2024 and overlapped the final year of the T2017 contract. The length of the contract is one transition year followed by eight annual option periods, which, if all options are exercised, would result in a total contract length of nine years.

Our CenterWell Segment Products

The products offered by our CenterWell segment are key to our integrated care delivery model. This segment includes our pharmacy solutions, primary care, and home solutions operations. The CenterWell segment also includes our strategic partnerships with Welsh, Carson, Anderson & Stowe, or WCAS, to develop and operate senior-focused, payor-agnostic, primary care centers, as well as our minority ownership interest in hospice operations. Services offered by this segment are designed to enhance the overall healthcare experience. These services may lead to lower utilization associated with improved member health and/or lower drug costs. For information on our intersegment revenues, refer to Note 18 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

The following table presents our services revenue for the CenterWell segment by line of business for the year ended December 31, 2024:

(dollars in millions)

n/a – not applicable

Pharmacy Solutions

Our pharmacy solutions business includes the operations of CenterWell Pharmacy (our mail-order pharmacy business), CenterWell Specialty Pharmacy, and other retail pharmacies located within CenterWell Primary Care clinics for brand, generic, specialty drugs, over the counter medications and supplies, as well as hospice pharmacy drugs.

Primary Care

We operate full-service, value-based senior focused primary care centers in a number of states, including Georgia, Florida, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Nevada, North Carolina, South Carolina, Tennessee, Texas, and Virginia staffed by primary care providers and medical specialists with a primary focus on the senior population under our Primary Care Organization, or PCO. PCO operates these clinics primarily under the Conviva Senior Primary Care and CenterWell Senior Primary Care brands. Our primary care subsidiaries operate our medical center business through both employed physicians and care providers, and through third-party management service organizations with whom we contract to arrange for and manage certain clinical services. PCO currently operates 344 primary care clinics and employs approximately 1,000 primary care providers. PCO serves approximately 390,500 patients, primarily under risk sharing arrangements with Humana Medicare Advantage health plans, third-party Medicare Advantage health plans and CMS administered risk sharing arrangements for Original Medicare.

PCO also operates a Medical Services Organization, or MSO, through Conviva and CenterWell that coordinates medical care for Medicare Advantage beneficiaries across multiple states. This MSO provides resources in care coordination, financial risk management, clinical integration and patient engagement that help physicians improve the patient experience as well as care outcomes. PCO’s MSO collaborates with physicians, medical groups and integrated delivery systems to successfully transition to value-based care by engaging, partnering and offering practical services and solutions.

In 2020, our Primary Care Organization entered into a strategic partnership with Welsh, Carson, Anderson & Stowe, or WCAS, to accelerate the expansion of our primary care model. In May 2022, we established a second strategic partnership with WCAS to develop additional centers between 2023 and 2025. As of December 31, 2024, there were 133 primary care clinics operating under the partnership and we have capacity to open or acquire up to approximately 20 additional centers through the existing partnership agreements. For additional information, refer to Note 4 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Home Solutions

CenterWell Home Health

We operate CenterWell Home Health, one of the nation's largest home health providers, through which we are actively involved in the care management of our customers with the greatest needs via in-home care. CenterWell Home Health has locations in 40 states, providing extensive geographic coverage with approximately 65% overlap with our individual Medicare Advantage membership. Our home solutions geographic scale and clinical breadth provides the opportunity to offer care beyond our health plan members. Through the integration of these home health operations, we are focused on accelerating clinical innovation and the development and roll out of a value-based operating model at scale, more closely aligning incentives to focus on improving patient outcomes and reducing the total cost of care. This is critical to deploying a value-based, advanced home health model at scale that makes it easier for patients and providers to benefit from our full continuum of home-based capabilities, leveraging the best channel to deliver the right care needed at the right time.

OneHome

OneHome serves as the convener for the value-based model meeting the needs of health plans by serving their members through a full-risk model for integrated home-based services. OneHome manages a full range of post-acute patient needs, integrating and coordinating with physicians, hospitals and health plans for the provision of home health and infusion services as well as the distribution of durable medical equipment, or DME, at patients’ homes.

Hospice

On August 11, 2022, we completed the sale of a 60% interest in Gentiva (formerly Kindred) Hospice, to Clayton, Dubilier & Rice, or CD&R. Upon closing, Gentiva Hospice was restructured into a new stand-alone company. We continue to own approximately 35% minority ownership in Gentiva Hospice operations. For additional information on the sale of Gentiva Hospice, refer to Note 3 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Insurance Medical Membership

The following table summarizes total insurance medical membership (in thousands) at December 31, 2024, by market and product:

Provider Arrangements

We provide our members with access to health care services through our networks of health care providers whom we employ or with whom we have contracted, including hospitals and other independent facilities such as outpatient surgery centers, primary care providers, specialist physicians, dentists, and providers of ancillary health care services and facilities. These ancillary services and facilities include laboratories, ambulance services, medical equipment services, home health agencies, mental health providers, rehabilitation facilities, nursing homes, optical services, and pharmacies. Our membership base and the ability to influence where our members seek care generally enable us to obtain contractual discounts with providers.

We use a variety of techniques to provide access to effective and efficient use of health care services for our members. These techniques include the coordination of care for our members, product and benefit designs, hospital inpatient management systems, the use of sophisticated analytics, and enrolling members into various care management programs. The focal point for health care services in many of our HMO networks is the primary care provider who, under contract with us, provides services to our members, and may control utilization of appropriate services by directing or approving hospitalization and referrals to specialists and other providers. Some physicians may have arrangements under which they can earn bonuses when certain target goals relating to the provision of quality patient care are met. We have available care management programs related to complex chronic conditions such as congestive heart failure and coronary artery disease. We also have programs for prenatal and premature infant care, asthma related illness, end stage renal disease, diabetes, cancer, and certain other conditions.

We typically contract with hospitals on either (1) a per diem rate, which is an all-inclusive rate per day, (2) a case rate for diagnosis-related groups (DRG), which is an all-inclusive rate per admission, or (3) a discounted charge for inpatient hospital services. Outpatient hospital services generally are contracted at a flat rate by type of service, ambulatory payment classifications, or APCs, or at a discounted charge. APCs are similar to flat rates except multiple services and procedures may be aggregated into one fixed payment. These contracts are often multi-year agreements. Outpatient surgery centers and other ancillary providers typically are contracted at flat rates per service provided or are reimbursed based upon a nationally recognized fee schedule such as the Medicare allowable fee schedule.

Our contracts with physicians typically are renewed automatically each year, unless either party gives written notice, generally ranging from 90 to 120 days, to the other party of its intent to terminate the arrangement. Most of the physicians in our PPO networks and some of our physicians in our HMO networks are reimbursed based upon a fixed fee schedule, which typically provides for reimbursement based upon a percentage of the standard Medicare allowable fee schedule.

The terms of our contracts with hospitals and physicians may also vary between Medicare and Medicaid business. A significant portion of our Medicare network contracts, including those with both hospitals and physicians, are tied to Medicare reimbursement levels and methodologies.

Capitation

We offer providers a continuum of opportunities to increase the integration of care and offer assistance to providers in transitioning from a fee-for-service to a value-based arrangement. These include performance bonuses, shared savings and shared risk relationships. For some of our medical membership, we share risk with providers under capitation contracts where physicians and hospitals accept varying levels of financial risk for a defined set of membership. Under the typical capitation arrangement, we prepay these providers a monthly fixed-fee per member, known as a capitation (per capita) payment, to cover all or a defined portion of the benefits provided to the capitated member.

We believe these value-based arrangements represent a key element of our integrated care delivery model at the core of our strategy. Our health plan subsidiaries may enter into these value-based arrangements with third-party providers or our owned provider subsidiaries.

At December 31, 2024, approximately 2,361,500 members, or 14.4%, of our medical membership, were covered under shared risk value-based arrangements, which provide all member benefits, including 2,114,900 individual Medicare Advantage members, or 38.0%, of our total individual Medicare Advantage membership.

Physicians under capitation arrangements typically have stop loss coverage so that a physician’s financial risk for any single member is limited to a maximum amount on an annual basis. We typically process all claims and measure the financial performance of our capitated providers and require guarantees in certain instances. However, we delegated claim processing functions under capitation arrangements covering approximately 304,400 members, including 303,500 individual Medicare Advantage members, or 14.4%, of the 2,114,900 individual Medicare Advantage members covered under shared risk value-based contracts at December 31, 2024, with the provider assuming substantially all the risk of coordinating the members’ health care benefits. Capitation expense under delegated arrangements for which we have a limited view of the underlying claims experience was approximately $3.6 billion, or 3.6%, of total benefits expense, for the year ended December 31, 2024. We remain financially responsible for health care services to our members in the event our providers fail to provide such services.

Accreditation Assessment

Our accreditation assessment program consists of several internal programs, including those that credential providers and those designed to meet the audit standards of federal and state agencies as well as external accreditation standards. We also offer quality and outcome measurement and improvement programs such as the Health Care Effectiveness Data and Information Set, or HEDIS, which is used by employers, government purchasers and the National Committee for Quality Assurance (NCQA) to evaluate health plans based on various criteria, including effectiveness of care and member satisfaction.

Providers participating in our networks must satisfy specific criteria, including licensing, patient access, office standards, after-hours coverage, and other factors. Most participating hospitals also meet accreditation criteria established by CMS and/or The Joint Commission.

Recredentialing of participating providers occurs every three years, unless otherwise required by state or federal regulations. Recredentialing of participating providers includes verification of their medical licenses, review of their malpractice liability claims histories, review of their board certifications, if applicable, and review of applicable quality information. A committee composed of a peer group of providers reviews the applications of providers being considered for credentialing and recredentialing.

We maintain accreditation for certain of our health plans and/or departments from NCQA, the Accreditation Association for Ambulatory Health Care (AAAHC), and/or URAC.

NCQA reviews our compliance based on standards for quality improvement, population health management, credentialing, utilization management, network management, and member experience. We have achieved and maintained NCQA health plan accreditation in many of our Medicare and Medicaid markets. Humana’s pharmacy organization is accredited by URAC.

Sales and Marketing

We use various methods to market our products, including television, radio, the Internet, telemarketing, wholesale distributors (general agencies) and direct mailings.

At December 31, 2024, we employed approximately 1,100 sales representatives, as well as approximately 2,700 telemarketing representatives who assisted in the marketing of Medicare products, including Medicare Advantage and PDP, and specialty products in our Insurance segment, including making appointments for sales representatives with prospective members. We have a marketing arrangement with Walmart Inc., or Walmart, for our individual Medicare stand-alone PDP offering. We also sell group Medicare Advantage products through large employers. In addition, we market our Medicare and individual specialty products through licensed independent brokers and agents. For our Medicare products, commissions paid to employed sales representatives and independent brokers and agents are based on a per unit commission structure, regulated in structure and amount by CMS. For our individual specialty products, we generally pay brokers a commission based on premiums, with commissions varying by market and premium volume. In addition to a commission based directly on premium volume for sales to particular customers, we also have programs that pay brokers and agents based on other metrics. These include commission bonuses based on sales that attain certain levels or involve particular products. We also pay additional commissions based on aggregate volumes of sales involving multiple customers.

In our Insurance segment, we market our specialty products to individuals through their employers or other groups, which typically offer employees or members a selection of specialty products, pay for all or part of the premiums, and make payroll deductions for any premiums payable by the employees. We use licensed independent brokers, independent agents, digital insurance agencies, and employees to sell our specialty products. We pay brokers and agents using the same commission structure described above for our specialty products.

Underwriting

Since 2014, the Patient Protection and Affordability Care Act and The Health Care and Education Reconciliation Act of 2010, which we collectively refer to as the Health Care Reform Law, requires certain group health plans to guarantee issuance and renew coverage without pre-existing condition exclusions or health-status rating adjustments. Accordingly, certain group health plans are not subject to underwriting. Further, underwriting techniques are not employed in connection with our individual Medicare, military services, or Medicaid products because government regulations require us to accept all eligible applicants regardless of their health or medical history.

Competition

The health benefits industry is highly competitive. Our competitors vary by local market and include other managed care companies, national insurance companies, and other HMOs and PPOs. Many of our competitors have a larger membership base and/or greater financial resources than our health plans in the markets in which we compete. Our ability to sell our products and to retain customers may be influenced by such factors as those described in Part I, Item 1A, "Risk Factors" of this Form 10-K.

Government Regulation

Diverse legislative and regulatory initiatives at both the federal and state levels continue to affect aspects of the nation’s health care system, including the Health Care Reform Law at the federal level and laws in certain states limiting the entry of new providers or services though a certificate of need, or CON, process.

Our management works proactively to ensure compliance with all governmental laws and regulations affecting our business. We are unable to predict how existing federal or state laws and regulations may be changed or interpreted, what additional laws or regulations affecting our businesses may be enacted or proposed, when and which of the proposed laws will be adopted or what effect any such new laws and regulations will have on our results of operations, financial position, or cash flows.

For a description of certain material current activities in the federal and state legislative areas, see Part I, Item 1A, "Risk Factors" of this Form 10-K.

Certain Other Services

Captive Insurance Company

We bear general business risks associated with operating our Company such as professional and general liability, employee workers’ compensation, cybersecurity, and officer and director errors and omissions risks. Professional and general liability risks may include, for example, medical malpractice claims and disputes with members regarding benefit coverage. We retain certain of these risks through our wholly-owned, captive insurance subsidiary. We reduce exposure to these risks by insuring levels of coverage for losses in excess of our retained limits with a number of third-party insurance companies. We remain liable in the event these insurance companies are unable to pay their portion of the losses.

Centralized Intercompany Services

We provide centralized intercompany services to each of our health plans and to our business segments from our headquarters and service centers. These services include management information systems, product development and administration, finance, human resources, accounting, law, public relations, marketing, insurance, purchasing, risk management, internal audit, actuarial, underwriting, claims processing, billing/enrollment, and customer service. Through intercompany service agreements approved, if required, by state regulatory authorities, Humana Inc., our parent company, charges a services fee for reimbursement of certain centralized services provided to its subsidiaries to the extent that Humana Inc. is the service provider.

Human Capital Management

Our associates are essential to our success in delivering on our core strategy, and creating positive healthcare experiences for our members. We are committed to recruiting, developing, and retaining strong and diverse teams. As of December 31, 2024, we had approximately 65,680 associates.

Our Culture, Engagement and Approach to Work

We believe that our members’ experience is linked to our associates’ experience and that engaged, productive associates are the key to building a healthy company and a caring environment where our associates go above and beyond for our members, driving innovation, and offering fulfilling experiences that incentivizes them to stay with us over the long-term. We provide opportunities for our associates to add to their personal well-being experiences that go beyond health to enhance their individual need for purpose, belonging and security. With an average tenure of 7 years at our Company, our associates’ loyalty reflects our culture and commitment to growth. We believe that voluntary turnover rate (VTR) is an important indicator of workforce satisfaction as we strive for our associates to choose us over other opportunities. During 2024, our VTR was 14.4%, representing an increase from 13.4% in 2023.

We regularly measure our success and seek opportunities to advance engagement through an Annual Engagement Survey, or AES, and continuous listening campaigns. Continuous listening involves our proactive solicitation, analysis and response to associate feedback throughout the year by using pulse surveys. By regularly surveying samples of our workforce, we are able to continuously assess our effectiveness and act when needed, which in turn helps to strengthen our culture and support associate engagement. We aim to conduct a confidential, third-party administered AES on an annual basis and encourage all of our associates to participate. The AES is an in-depth survey covering eighteen dimensions that align to the Company’s strategy and employee engagement. We aggregate survey results, provide them to our entire associate population and encourage leaders to use the information to create open, honest action plans with their teams to build upon our collective engagement.

Pay and Benefits Philosophy, Compensation and Financial Security

We believe all of our associates have the right to receive a competitive wage and we are committed to maintaining a pay and benefits philosophy that is market-based and recognizes an associate’s contributions so that we can attract and retain an engaged, talented team. Further, we believe in fostering a fair and inclusive work environment, one where all associates receive equitable pay for their contributions. Each year, we conduct a comprehensive pay equity/gap analysis to identify and address potential pay disparities between associates performing similar work in similar capacities. Our pay and benefits structure is designed to motivate, incentivize and reward our associates, at all levels of the organization, for their skill development, demonstration of our values and performance. While our programs vary by location, associate type and business, they generally include:

Talent Development and Growth Opportunities

We are committed to promoting continuous learning and growth by offering employees a comprehensive range of resources to enhance their skills and advance their careers. Our professional development initiatives ensure employees have access to tools, mentorship and opportunities that enable them to succeed in their current roles and prepare for future growth opportunities, thereby strengthening our organization and driving innovation. We also offer our associates education and certification program assistance through partner organizations, and reduce or eliminate cost barriers to support achievement of their educational and career goals.

Risks Relating to Our Business

If we do not design and price our products properly and competitively, if the premiums we charge are insufficient to cover the cost of health care services delivered to our members, if we are unable to implement clinical initiatives to provide a better health care experience for our members, lower costs and appropriately document the risk profile of our members, or if our estimates of benefits expense are inadequate, our profitability may be materially adversely affected. We estimate the costs of our benefits expense payments, and design and price our products accordingly, using actuarial methods and assumptions based upon, among other relevant factors, claim payment patterns, medical cost inflation, and historical developments such as claim inventory levels and claim receipt patterns. These estimates involve extensive judgment, and have considerable inherent variability because they are extremely sensitive to changes in claim payment patterns and medical cost trends. Accordingly, our reserves may be insufficient.

We use a substantial portion of our revenues to pay the costs of health care services delivered to our members, including claims payments, capitation payments to providers (predetermined amounts paid to cover services), estimates of future payments to hospitals and others for medical care provided to our members, and various other costs. Generally, premiums in the health care business are fixed for one-year periods. Accordingly, costs we incur in excess of our benefit cost projections generally are not recovered in the contract year through higher premiums. We estimate the costs of our future benefit claims and other expenses using actuarial methods and assumptions based upon claim payment patterns, medical inflation, historical developments, including claim inventory levels and claim receipt patterns, and other relevant factors. We also record benefits payable for future payments. We continually review estimates of future payments relating to benefit claims costs for services incurred in the current and prior periods and make necessary adjustments to our reserves, including premium deficiency reserves where appropriate. However, these estimates involve extensive judgment, and have considerable inherent variability that is sensitive to claim payment patterns and medical cost trends. Many factors may and often do cause actual health care costs to exceed what was estimated and used to set our premiums. These factors may include:

• increased use of medical facilities and services, and the increased cost of such services;
• increased use or cost of prescription drugs, including specialty prescription drugs;
• the introduction of new or costly treatments, prescription drugs, or new technologies;
• our membership mix;
• variances in actual versus estimated levels of cost associated with new products, benefits or lines of business, product changes or benefit level changes;
• changes in the demographic characteristics of an account or market;
• changes or reductions of our utilization management functions such as preauthorization of services, concurrent review or requirements for physician referrals;
• changes in our purchase discounts or rebates received from manufacturers and wholesalers;
• pharmacy volume rebates received from drug manufacturers, which in Medicare Part D are fully reported to CMS and factored into member premium pricing and CMS reimbursement to the plan;
• catastrophes, including acts of terrorism, public health emergencies, epidemics or pandemics (such as COVID-19), or natural disasters (such as hurricanes and earthquakes) which could occur more frequently or with more intense effects as a result of the impact of global climate change;
• medical cost inflation; and
• government mandated benefits, member eligibility criteria, or other legislative, judicial, or regulatory changes.

Key to our operational strategy is the implementation of clinical initiatives that we believe provide a better health care experience for our members, lower the cost of healthcare services delivered to our members, and appropriately document the risk profile of our members. Our profitability and competitiveness depend in large part on our ability to appropriately manage health care costs through, among other things, the application of medical management programs such as our chronic care management program.

While we proactively attempt to effectively manage our operating expenses, increases or decreases in staff-related expenses, any costs associated with exiting products, additional investment in new products (including our opportunities in the Medicare programs, state-based contracts, and expansion of clinical capabilities as part of our integrated care delivery model), investments in health and well-being product offerings, acquisitions, new taxes and assessments, inflation, and implementation of regulatory requirements may increase our operating expenses.

Failure to adequately price our products or estimate sufficient benefits payable or effectively manage our operating expenses, may result in a material adverse effect on our results of operations, financial position, and cash flows.

We are in a highly competitive industry. Some of our competitors are more established in the health care industry in terms of a larger market share and have greater financial resources than we do in some markets. In addition, other companies may enter our markets in the future, including emerging competitors in the Medicare program or competitors in the delivery of health care services. We believe that barriers to entry in our markets are not substantial, so the addition of new competitors can occur relatively easily, and customers enjoy significant flexibility in moving between competitors through the Medicare Annual Enrollment Period. While health plans compete on the basis of many factors, including service and the quality and depth of provider networks, we expect that price will continue to be a significant basis of competition. In addition to the challenge of controlling health care costs, we face intense competitive pressure to contain premium prices. Factors such as business consolidations, strategic alliances, legislative and regulatory reform, and marketing practices create pressure to contain premium price increases, despite being faced with increasing medical and administrative costs.

The policies and decisions of the federal and state governments regarding the Medicare Advantage and Prescription Drug Plans, military services and Medicaid programs in which we participate have a substantial impact on our profitability. These governmental policies and decisions, which we cannot predict with certainty, directly shape the premiums or other revenues to us under the programs, the eligibility and enrollment of our members, the services we provide to our members, and our administrative, health care services, and other costs associated with these programs. Legislative or regulatory actions, such as changes to the programs in which we participate, those resulting in a reduction in premium payments to us, an increase in our cost of administrative and health care services, or additional fees, taxes or assessments, may have a material adverse effect on our results of operations, financial position, and cash flows.

Premium increases, introduction of new product designs, and our relationships with our providers in various markets, among other issues, could also affect our membership levels. Other actions that could affect membership levels include our possible exit from or entrance into Medicare or commercial markets, or the termination of a large contract.

If we do not compete effectively in our markets, if we set rates too high or too low in highly competitive markets to keep or increase our market share, if membership does not increase as we expect, if membership declines, or if we lose membership with favorable medical cost experience while retaining or increasing membership with unfavorable medical cost experience, our results of operations, financial position, and cash flows may be materially adversely affected.

If we fail to effectively implement our operational and strategic initiatives, including our Medicare initiatives, which are of particular importance given the concentration of our revenues in these products, our state-based contracts strategy, the growth of our CenterWell businesses, and our integrated care delivery model, our business may be materially adversely affected.

Our future performance depends in large part upon our ability to execute our strategy, including opportunities created by the expansion of our Medicare programs, our strategy with respect to state-based contracts, including those covering members dually eligible for the Medicare and Medicaid programs, the growth of our pharmacy, primary care, and home solutions businesses, and the successful implementation of our integrated care delivery model.

We have made substantial investments in the Medicare program to enhance our ability to participate in these programs. The growth of our Medicare products is an important part of our business strategy, and the attendant concentration of revenues intensifies the risks to us inherent in Medicare products. Any failure to achieve this growth may have a material adverse effect on our results of operations, financial position, or cash flows.

The number of our Medicare Advantage plans rated 4-star or higher will significantly decline in 2025. We have filed a lawsuit seeking to set aside and vacate the 2025 Star Ratings of our Medicare Advantage plans, but there is no assurance that we will prevail in this lawsuit. If we are not successful, the decline in our Star Ratings will negatively impact our 2026 quality bonus payments from CMS and may also significantly adversely affect our revenues, operating results, and cash flows. In addition, there can be no assurances that we will be successful in maintaining or improving our Star Ratings in future years.

The achievement of Star Ratings of 4-star or higher qualifies Medicare Advantage plans for premium bonuses. Our Medicare Advantage plans' operating results may be significantly affected by their star ratings. Uncertainties with respect to both ongoing changes to the Star Ratings system and CMS cut-points for establishing a plan’s performance with respect to star rating measures, which are not determined until after the relevant measurement period, continue to make accurate prediction of each Medicare Advantage plan’s Star Ratings more challenging. Despite our operational efforts to improve our Star Ratings, there can be no assurances that we will be successful in maintaining or improving our Star Ratings in future years. In addition, audits of our performance for past or future periods may result in downgrades to our star ratings. Accordingly, our plans may not be eligible for full level quality bonuses or may not match the performance of our competitors, each of which could materially and adversely affect the benefits such plans can offer, reduce membership and/or reduce profit margins, which may significantly adversely affect our revenues, operating results, and cash flows.

Based on 2025 Medicare Advantage Star Ratings released by CMS in October 2024, approximately 25% of our Medicare Advantage members are currently enrolled in plans rated 4-star or higher for 2025, as compared to 94% based on our 2024 Star Ratings. We have filed a lawsuit that, among other things, seeks to set aside and vacate the 2025 Star Ratings for our Medicare Advantage plans, but there is no assurance that we will prevail in the lawsuit. If we are not successful, the decline in our Star Ratings performance for 2025 will negatively impact our 2026 quality bonus payments from CMS and may also significantly adversely affect our revenues, operating results, and cash flows. Please see “Legal Proceedings and Certain Regulatory Matters” in Note 17 to the Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K for a description of the lawsuit.

If we fail to properly maintain the integrity of our data, to strategically maintain existing or implement new information systems, or to protect our proprietary rights to our systems, our business may be materially adversely affected.

Our business depends significantly on effective information systems and the integrity and timeliness of the data we use to run our business. Our business strategy involves providing members and providers with easy to use products that leverage our information to meet their needs. Our ability to adequately price our products and services, provide effective and efficient service to our customers, develop new and innovative products and services (including enhanced technologies that improved connectivity across products and meet consumer expectations for engaging in their health care), automate and deploy new technologies to simplify administrative processes and clinical decision making, provide timely payments to care providers, drive administrative and operational efficiencies, and timely and accurately report our financial results depends significantly on the performance of, and integrity of the data, in our information systems. These systems require an ongoing commitment of significant resources to maintain, protect, and enhance existing systems and develop and integrate new systems, including systems powered by or incorporating artificial intelligence and machine learning (including generative AI) (AI/ML), to keep pace with continuing changes in information processing technology, evolving industry and regulatory standards, and changing customer preferences, and even with such resources there is no assurance that we will be able to do so. If the information we rely upon to run our businesses was found to be inaccurate, unreliable, or biased, if we fail to improve service levels or maintain the integrity of our data, or if we fail to effectively maintain our information systems and develop and integrate new systems (including systems powered by or incorporating AI/ML), or if our use of AI/ML technologies were to result in inaccuracies, biases or errors, we could have operational disruptions, problems in determining medical cost estimates and establishing appropriate pricing, customer and health care provider disputes, reputational challenges, regulatory or other legal obstacles (including potential investigations and enforcement), difficulty preventing and detecting fraud, increases in operating expenses, difficulty driving administrative or operational efficiencies to enhance our operations and reduce costs, loss of existing customers, difficulty in attracting new customers, or other adverse consequences, each of which may result in a material adverse effect on our results of operations, financial position, and cash flows.

We depend on independent third parties for significant portions of our systems-related support, equipment, facilities, and certain data, including data center operations, data network, voice communication services and pharmacy data processing. This dependence makes our operations vulnerable to such third parties' failure to perform adequately under the contract, due to internal or external factors. A change in service providers could result in a decline in service quality and effectiveness or less favorable contract terms which may adversely affect our operating results.

We rely on our agreements with customers and service providers, confidentiality agreements with employees, and our trade secrets and copyrights to protect our proprietary rights. These legal protections and precautions may not prevent misappropriation of our proprietary information. The misappropriation of our proprietary information could hinder our ability to market and sell products and services and may result in a material adverse effect on our results of operations, financial position and cash flows.

If we, and the third-party service providers on whom we rely, are unable to defend our information technology systems against cybersecurity attacks, contain such attacks when they occur, or prevent other privacy or data security incidents that result in security breaches that disrupt our operations or in the unintentional dissemination of sensitive personal information or proprietary or confidential information, we could be exposed to significant regulatory fines or penalties, liability or reputational damage, or experience a material adverse effect on our results of operations, financial position, and cash flows.

In the ordinary course of our business, we process, store and transmit large amounts of data, and rely on third-party service providers to do the same, including protected personal information subject to privacy, security or data breach notification laws, as well as proprietary or confidential information relating to our business or a third-party with which we do business. We have been, and will likely continue to be, regular targets of attempted cybersecurity attacks and other security threats and may be, and have been, subject to breaches of our information technology systems, including breaches of the information technology systems of third-party service providers. Although the impact of such attacks has not been material to our operations or results of operations, financial position, or cash flow through December 31, 2024, we can provide no assurance that we will be able to detect, prevent, or contain the effects of such cybersecurity attacks or other information security risks or threats, or that such an attack will not be material to our business, in the future. Further, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and are increasing in sophistication, in part due to use of evolving AI/ML technologies (including generative AI), and because our businesses are changing as well, we may be unable to anticipate these techniques and threats, detect data security incidents or implement adequate preventive measures. A cybersecurity attack may penetrate our layered security controls and lead to the misappropriation of or compromise of protected personal information or proprietary or confidential information, create system disruptions, cause shutdowns, or deploy viruses, ransomware, and other malicious software programs that attack our systems or those of our third-party service providers. A cybersecurity attack that bypasses our information technology systems, or the security of our third-party service providers, could materially affect us due to the theft, destruction, loss, misappropriation or release of confidential information or intellectual property, operational or business delays resulting from the disruption of our IT systems, extortion attempts, or negative publicity resulting in reputation or brand damage with our members, customers, providers, and other stakeholders.

The costs to detect, prevent, eliminate or address cybersecurity threats and vulnerabilities before or after an incident could be substantial. Our remediation efforts may not be successful and could result in interruptions, delays, or cessation of service, and loss of existing or potential members. In addition, breaches of our security measures or the security measures of third-party service providers, and the unauthorized dissemination of protected personal information or proprietary or confidential information about us or our customers or other third-parties, can expose our associates' or customers’ private information and result in the risk of financial or medical identity theft, or expose us or other third-parties to a risk of loss or misuse of this information, result in significant regulatory fines or penalties, litigation and potential liability for us, damage our brand and reputation, or otherwise harm our business.

We are involved in various legal actions and governmental and internal investigations, any of which, if resolved unfavorably to us, could result in substantial monetary damages or changes in our business practices. Increased litigation and negative publicity could increase our cost of doing business.

We are or may become a party to a variety of legal actions that affect our business, including breach of contract actions, employment compensation and other labor and employment practice suits, employee benefit claims, stockholder suits and other securities laws claims, intellectual and other property claims, and tort claims.

In addition, because of the nature of the health care business, we are subject to a variety of legal actions relating to our business operations, including the design, management, and offering of products and services. These include and could include in the future: claims relating to the methodologies for calculating premiums; claims relating to the denial of health care benefit payments; claims relating to the denial or rescission of insurance coverage; challenges to the use of some software products used in administering claims; claims relating to our administration of our Medicare Part D offerings; medical malpractice actions brought against our employed providers or affiliated physician-owned professional groups, or against our health plans based on our medical necessity decisions or brought against us on the theory that we are liable for a third-party providers' alleged malpractice; claims arising from any adverse medical consequences resulting from our recommendations about the appropriateness of providers’ proposed medical treatment plans for patients; allegations of anti-competitive and unfair business activities; provider disputes over compensation or non-acceptance or termination of provider contracts; false claims litigation, such as qui tam lawsuits, brought by individuals who seek to sue on behalf of the government, alleging that we, as a government contractor, submitted false claims to the government or retained overpayments from the government, among other allegations, resulting from coding and review practices under the Medicare risk-adjustment model; claims related to the failure to disclose some business practices; claims relating to customer audits and contract performance; claims relating to dispensing of drugs associated with our in-house dispensing pharmacies; and professional liability claims arising out of the delivery of healthcare and related services to the public.

In some cases, substantial non-economic or punitive damages as well as treble damages under the federal False Claims Act, Racketeer Influenced and Corrupt Organizations Act and other statutes may be sought.

While we currently have insurance coverage for some of these potential liabilities, other potential liabilities may not be covered by insurance, insurers may dispute coverage, or the amount of our insurance may not be enough to cover the damages awarded. In addition, some types of damages, like punitive damages, may not be covered by insurance. In some jurisdictions, coverage of punitive damages is prohibited. Insurance coverage for all or some forms of liability may become unavailable or prohibitively expensive in the future.

The health benefits industry continues to receive significant negative publicity reflecting the public perception of the industry. This publicity and perception have been accompanied by increased litigation, including some large jury awards, legislative activity, regulation, and governmental review of industry practices. These factors may materially adversely affect our ability to market our products or services, may require us to change our products or services or otherwise change our business practices, may increase the regulatory burdens under which we operate, and may require us to pay large judgments or fines. Any combination of these factors could further increase our cost of doing business and adversely affect our results of operations, financial position, and cash flows.

See "Legal Proceedings and Certain Regulatory Matters" in Note 17 to the audited Consolidated Financial Statements included in Item 8. - Financial Statements and Supplementary Data. We cannot predict the outcome of these matters with certainty.

As a government contractor, we are exposed to risks that may materially adversely affect our business or our willingness or ability to participate in government health care programs.

A significant portion of our revenues relates to federal and state government health care coverage programs, including the Medicare, military services, and Medicaid programs. These programs accounted for approximately 94% of our total premiums and services revenue for the year ended December 31, 2024. These programs involve various risks, as described further below.

• At December 31, 2024, under our contracts with CMS we provided health insurance coverage to approximately 924,800 individual Medicare Advantage members in Florida. These contracts accounted for approximately 14% of our total premiums and services revenue for the year ended December 31, 2024. The loss of these and other CMS contracts (which are generally renewed annually) or significant changes in the Medicare Advantage and Prescription Drug Plan programs as a result of legislative or regulatory action, including changes to the Part D prescription drug benefit design (such as the changes to plan sponsor liability across the different Part D coverage phases that will apply beginning in plan year 2025) or reductions in premium payments to us or increases in member benefits or changes to member eligibility criteria without corresponding increases in premium payments to us, may have a material adverse effect on our results of operations, financial position, and cash flows.
• Our military services business, which accounted for approximately 1% of our total premiums and services revenue for the year ended December 31, 2024, primarily consisted of the TRICARE T2017 East Region contract. We delivered services under the T2017 East Region contract from commencement on January 1, 2018 through expiration on December 31, 2024. The T2017 East Region contract comprised 32 states and approximately 6 million TRICARE beneficiaries. In December 2022, we were awarded the next generation of TRICARE Managed Care Support Contracts, or T-5, for the updated TRICARE East Region by the Defense Health Agency of the DoD. The T-5 East Region contract commenced on January 1, 2025 and comprises 24 states, and Washington D.C., and approximately 4.6 million beneficiaries. The transition period for the T-5 contract began in January 2024 and overlapped the final year of the T2017 contract. The length of the contract is one transition year followed by eight annual option periods, which, if all options are exercised, would result in a total contract length of nine years.
• CMS uses a risk-adjustment model which adjusts premiums paid to Medicare Advantage, or MA, plans according to health status of covered members. The risk-adjustment model, which CMS implemented pursuant to the Balanced Budget Act of 1997 (BBA) and the Benefits Improvement and Protection Act of 2000 (BIPA), generally pays more where a plan's membership has higher expected costs. Under this model, rates paid to MA plans are based on actuarially determined bids, which include a process whereby our prospective payments are based on our estimated cost of providing standard Medicare-covered benefits to an enrollee with a "national average risk profile." That baseline payment amount is adjusted to account for certain demographic characteristics and health status of our enrolled members. Under the risk-adjustment methodology, all MA plans must collect from providers and submit the necessary diagnosis code information to CMS within prescribed deadlines. The CMS risk-adjustment model uses the diagnosis data, collected from providers, to calculate the health status-related risk-adjusted premium payment to MA plans, which CMS further adjusts for coding pattern differences between the health plans and the government fee-for-service (FFS) program. We generally rely on providers, including certain providers in our network who are our employees, to code their claim submissions with appropriate diagnoses, which we send to CMS as the basis for our health status-adjusted payment received from CMS under the actuarial risk-adjustment model. We also rely on these providers to document appropriately all medical data, including the diagnosis data submitted with claims. In addition, we

conduct medical record reviews as part of our data and payment accuracy compliance efforts, to more accurately reflect diagnosis conditions under the risk adjustment model.

CMS and the Office of the Inspector General of Health and Human Services, or HHS-OIG, perform audits of various companies’ risk adjustment diagnosis data submissions. We refer to these audits as Risk-Adjustment Data Validation Audits, or RADV audits. RADV audits review medical records in an attempt to validate provider medical record documentation and coding practices that influence the calculation of health status-related premium payments to MA plans.

In 2012, CMS released an MA contract-level RADV methodology that would extrapolate the results of each CMS RADV audit sample to the audited MA contract’s entire health status-related risk adjusted premium amount for the year under audit. In doing so, CMS recognized “that the documentation standard used in RADV audits to determine a contract’s payment error (medical records) is different from the documentation standard used to develop the Part C risk-adjustment model (FFS claims).” To correct for this difference, CMS stated that it would apply a “Fee-for-Service Adjuster (FFS Adjuster)” as “an offset to the preliminary recovery amount.” This adjuster would be “calculated by CMS based on a RADV-like review of records submitted to support FFS claims data.” CMS stated that this methodology would apply to audits beginning with PY 2011. Humana relied on CMS’s 2012 guidance in submitting MA bids to CMS. Humana also launched a “Self-Audits” program in 2013 that applied CMS’s 2012 RADV audit methodology and included an estimated FFS Adjuster. Humana completed Self-Audits for PYs 2011-2016 and reported results to CMS.

In October 2018, however, CMS issued a proposed rule announcing possible changes to the RADV audit methodology, including elimination of the FFS Adjuster. CMS proposed applying its revised methodology, including extrapolated recoveries without application of a FFS Adjuster, to RADV audits dating back to PY 2011. On January 30, 2023, CMS published a final rule related to the RADV audit methodology (Final RADV Rule). The Final RADV Rule confirmed CMS’s decision to eliminate the FFS Adjuster. The Final RADV Rule states CMS’s intention to extrapolate results from CMS and HHS-OIG RADV audits beginning with PY 2018, rather than PY 2011 as proposed. However, CMS’s Final RADV Rule does not adopt a specific sampling, extrapolation or audit methodology. CMS instead stated its general plan to rely on “any statistically valid method . . . that is determined to be well-suited to a particular audit.”

We believe that the Final RADV Rule fails to address adequately the statutory requirement of actuarial equivalence and violates the Administrative Procedure Act (“APA”). CMS failed to meet its legal obligations in the federal rulemaking process to give a reasoned justification for the rule or provide a meaningful opportunity for public comment. They also chose to apply the rule retroactively rather than prospectively, as required by law. Humana’s actuarially certified bids through PY 2023 preserved Humana’s position that CMS should apply an FFS Adjuster in any RADV audit that CMS intends to extrapolate. CMS confirmed its intent to apply the Final RADV Rule, including the first application of extrapolated audit results to determine audit settlements without the use of a FFS Adjuster, to CMS audits conducted for PY 2018 and subsequent years when it selected certain of Humana's MA contracts for PY 2018 RADV Audits. The Final RADV Rule, including the lack of a FFS Adjuster, and any related regulatory, industry or company reactions, could have a material adverse effect on our results of operations, financial position, or cash flows.

On September 1, 2023, Humana Inc. and Humana Benefit Plan of Texas, Inc. filed suit against the United States Department of Health and Human Services, and Xavier Becerra in his official capacity as Secretary, in the United States District Court, Northern District of Texas, Fort Worth Division seeking a determination that the Final RADV Rule violates the APA and should be set aside. We remain committed to working alongside CMS to promote the integrity of the MA program as well as affordability and cost certainty for our members. It is critical that MA plans are paid accurately and that payment model principles, including the application of a FFS Adjuster, are in accordance with the requirements of the

Social Security Act, which, if not implemented correctly could have a material adverse effect on our results of operations, financial position, or cash flows.

In addition, as part of our internal compliance efforts, we routinely perform ordinary course reviews of our internal business processes related to, among other things, our risk coding and data submissions in connection with the risk adjustment model. These reviews may also result in the identification of errors and the submission of corrections to CMS that may, either individually or in the aggregate, be material. As such, the result of these reviews may have a material adverse effect on our results of operations, financial position, or cash flows.

• Our CMS contracts which cover members’ prescription drugs under Medicare Part D contain provisions for risk sharing and certain payments for prescription drug costs for which we are not at risk. These provisions, certain of which are described below, affect our ultimate payments from CMS.

The premiums from CMS are subject to risk corridor provisions which compare costs targeted in our annual bids to actual prescription drug costs, limited to actual costs that would have been incurred under the standard coverage as defined by CMS. Variances exceeding certain thresholds may result in CMS making additional payments to us or require us to refund to CMS a portion of the premiums we received (known as a “risk corridor”). We estimate and recognize an adjustment to premiums revenue related to the risk corridor payment settlement based upon pharmacy claims experience. The estimate of the settlement associated with these risk corridor provisions requires us to consider factors that may not be certain until CMS completes the applicable final payment year reconciliation, including member eligibility differences with CMS incurred allowable drug costs after rebates and other discounts, and low-income subsidy amounts.

Reinsurance and low-income cost subsidies represent payments from CMS in connection with the Medicare Part D program for which we assume no risk. Reinsurance subsidies represent payments for CMS’s portion of claims costs which exceed the member’s out-of-pocket threshold, or the catastrophic coverage level. Low-income cost subsidies represent payments from CMS for all or a portion of the deductible, the coinsurance and co-payment amounts above the out-of-pocket threshold for low-income beneficiaries. Monthly prospective payments from CMS for reinsurance and low-income cost subsidies are based on assumptions submitted with our annual bid. A reconciliation and settlement of CMS’s prospective subsidies against actual prescription drug costs we paid is made after the end of the applicable year.

Settlement of the reinsurance and low-income cost subsidies as well as the risk corridor payment is based on a reconciliation made approximately 9 months after the close of each calendar year. This reconciliation process requires us to submit claims data necessary for CMS to administer the program. Our claims data may not pass CMS’s claims edit processes due to various reasons, including discrepancies in eligibility or classification of low-income members. To the extent our data does not pass CMS’s claim edit processes, we may bear the risk for all or a portion of the claim which otherwise may have been subject to the risk corridor provision or payment which we would have otherwise received as a low-income subsidy or reinsurance claim. In addition, in the event the settlement represents an amount CMS owes us, there is a negative impact on our cash flows and financial condition as a result of financing CMS’s share of the risk. The opposite is true in the event the settlement represents an amount we owe CMS. Further, legislative or regulatory changes to how actual prescription drug costs are reported or calculated or other changes to the Part D prescription drug benefit design may lower reinsurance or low-income cost subsidies paid by CMS and may have a material adverse effect on our results of operations, financial position, or cash flows.

• Our primary care and home solutions businesses derive a substantial portion of their revenues from third-party payors and directly from the federal and state governments through participation in fee-for-service Medicare. This concentration of revenues subjects these businesses to reductions in Medicare reimbursement rates or changes in the rules governing the Medicare program, including changes to

CMS’s risk adjustment model that may apply to our primary care business through its contracts with third-party payors. It is reasonably possible that such changes in reimbursement rates or changes to the Medicare programs in which our primary care and home health business participate may have a material adverse effect on our results of operations, financial position, or cash flows.

• We are subject to various other governmental audits and investigations. Under state laws, our HMOs and health insurance companies are audited by state departments of insurance for financial and contractual compliance. Our HMOs are audited for compliance with health services by state departments of health. Audits and investigations, including audits of risk adjustment data, are also conducted by state attorneys general, CMS, HHS-OIG, the Office of Personnel Management, the Department of Justice, the Department of Labor, and the Defense Contract Audit Agency. All of these activities could result in the loss of licensure or temporary or permanent exclusion from participating in various government health care programs (such as Medicare and Medicaid), including a limitation on our ability to market or sell products, the imposition of fines, penalties and other civil and criminal sanctions, or changes in our business practices. The outcome of any current or future governmental or internal investigations cannot be accurately predicted, nor can we predict any resulting penalties, fines or other sanctions that may be imposed at the discretion of federal or state regulatory authorities. Nevertheless, it is reasonably possible that any such outcome of litigation, penalties, fines or other sanctions could be substantial, and the outcome of these matters may have a material adverse effect on our results of operations, financial position, and cash flows. Certain of these matters could also affect our reputation. In addition, disclosure of any adverse investigation or audit results or sanctions could negatively affect our industry or our reputation in various markets and make it more difficult for us to sell our products and services.

Our business activities are subject to substantial government regulation. New laws or regulations, or legislative, judicial, or regulatory changes in existing laws or regulations or their manner of application could increase our cost of doing business and may have a material adverse effect on our results of operations, or cash flows.

New Laws or Regulations, or Future Legislative, Judicial or Regulatory Changes

We are and will continue to be regularly subject to new laws and regulations, changes to existing laws and regulations, and judicial determinations that impact the interpretation and applicability of those laws and regulations. The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010 (which we collectively refer to as the Health Care Reform Law), the Families First Coronavirus Response Act (the “Families First Act”), the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), and the Inflation Reduction Act of 2022 (the “Inflation Reduction Act”), and related regulations, are examples of laws which have enacted significant reforms to various aspects of the U.S. health insurance industry, including among others, mandated coverage requirements, mandated benefits and guarantee issuance associated with commercial medical insurance, rebates to policyholders based on minimum benefit ratios, adjustments to Medicare Advantage premiums, the establishment of federally facilitated or state-based exchanges coupled with programs designed to spread risk among insurers, the introduction of plan designs based on set actuarial values, and changes to the Part D prescription drug benefit design.

It is reasonably possible that these laws and regulations, as well as other current or future legislative, judicial or regulatory changes, including restrictions on our ability to manage our provider network, market and sell our products, or otherwise operate our business, or restrictions on profitability, including reviews by regulatory bodies that may compare our Medicare Advantage business profitability to our non-Medicare Advantage business profitability, or compare the profitability of various products within our Medicare Advantage business, and require that they remain within certain ranges of each other, increases in member benefits or changes to member eligibility criteria without corresponding increases in premium payments to us, further restrictions on service arrangements and fee payments between intercompany or vertically-integrated assets, increases in regulation of our prescription drug benefit businesses, or changes to the Part D prescription drug benefit design (and uncertainty arising from the implementation of these changes) may have a material adverse effect on our results of operations (including restricting revenue, enrollment and premium growth in certain products and market segments, restricting our ability to expand into new markets, increasing our medical and operating costs, further lowering our Medicare payment rates and increasing our expenses associated with assessments); our financial position (including our ability to maintain the value of our goodwill); and our cash flows.

Additionally, potential legislative changes or judicial determinations, including activities to repeal or replace these laws and regulations, including the Health Care Reform Law or declare all or certain portions of these laws and regulations unconstitutional or contrary to law, create uncertainty for our business, and we cannot predict when, or in what form, such legislative changes or judicial determinations may occur.

Health Insurance Portability and Accountability Act (HIPAA) and the Health Information Technology for Economic and Clinical Health Act (HITECH Act)

The use of individually identifiable health data by our business is regulated at federal and state levels. These laws and rules are changed frequently by legislation or administrative interpretation. Various state laws address the use and maintenance of individually identifiable health data. Most are derived from the privacy provisions in the federal Gramm-Leach-Bliley Act and the Health Insurance Portability and Accountability Act, or HIPAA. HIPAA includes administrative provisions directed at simplifying electronic data interchange through standardizing transactions, establishing uniform health care provider, payer, and employer identifiers, and seeking protections for the confidentiality and security of patient data. The rules do not provide for complete federal preemption of state laws, but rather preempt all inconsistent state laws unless the state law is more stringent. These regulations set standards for the security of electronic health information, including requirements that insurers provide customers with notice regarding how their non-public personal information is used, including an opportunity to "opt out" of certain disclosures.

The HITECH Act, one part of the American Recovery and Reinvestment Act of 2009, significantly broadened and strengthened the scope of the privacy and security regulations of HIPAA and imposes additional limits on the use and disclosure of protected health information, or PHI. Among other requirements, the HITECH Act and HIPAA requires us and other covered entities to report any unauthorized release or use of or access to PHI to any impacted individuals and to HHS in those instances where the unauthorized activity poses a significant risk of financial, reputational or other harm to the individuals, and to notify the media in any states where 500 or more people are impacted by any unauthorized release or use of or access to PHI, requires business associates to comply with certain provisions of the HIPAA privacy and security rule, and grants enforcement authority to state attorneys general in addition to the HHS Office of Civil Rights.

In addition, there are numerous federal and state laws and regulations addressing patient and consumer privacy concerns, including unauthorized access or theft of personal information. State statutes and regulations vary from state to state and could impose additional penalties. Violations of HIPAA or applicable federal or state laws or regulations could subject us to significant criminal or civil penalties, including significant monetary penalties. Compliance with HIPAA and other privacy regulations requires significant systems enhancements, training and administrative effort. HIPAA can also expose us to additional liability for violations by our business associates (e.g., entities that provide services to health plans and providers).

Corporate Practice of Medicine and Other Laws

As a corporate entity, Humana Inc. is not licensed to practice medicine. Many states in which we operate through our subsidiaries limit the practice of medicine to licensed individuals or professional organizations comprised of licensed individuals, and business corporations generally may not exercise control over the medical decisions of physicians. Statutes and regulations relating to the practice of medicine, fee-splitting between physicians and referral sources, and similar issues vary widely from state to state. Under management agreements between certain of our subsidiaries and affiliated physician-owned professional groups, these groups retain sole responsibility for all medical decisions, as well as for hiring and managing physicians and other licensed healthcare providers, developing operating policies and procedures, implementing professional standards and controls, and maintaining malpractice insurance. We believe that our health services operations comply with applicable state statutes regarding corporate practice of medicine, fee-splitting, and similar issues. However, any enforcement actions by governmental officials alleging non-compliance with these statutes, which could subject us to penalties or restructuring or reorganization of our business, may result in a material adverse effect on our results of operations, financial position, or cash flows.

Anti-Kickback, Physician Self-Referral, and Other Fraud and Abuse Laws

We are subject to various federal and state healthcare fraud and abuse laws including the federal False Claims Act (the “False Claims Act”), the federal anti-kickback statute (the “Anti-Kickback Statute”), the federal “Stark Law,” and related state laws. Potential sanctions for violating these laws include recoupment or reduction of government reimbursement amounts, civil penalties, treble damages, and exclusion from participating in the Medicare and Medicaid programs or other government healthcare programs. The False Claims Act prohibits knowingly submitting, conspiring to submit, or causing to be submitted, false claims, records, or statements to the federal government, or intentionally failing to return overpayments, in connection with reimbursement by federal government programs. The Anti-Kickback Statute prohibits the offer, payment, solicitation, or receipt of any form of remuneration to induce, or in return for, the referral of business under Medicare or other governmental health program. The Stark Law prohibits physicians from referring Medicare or Medicaid beneficiaries for certain services to any entity with which the physician, or an immediate family member of the physician, has a financial relationship, unless the financial relationship fits within a permissible exception.

Many states also have enacted laws similar in scope and purpose to the Anti-Kickback Statute and, in more limited instances, the Stark Law, that are not limited to services for which Medicare or Medicaid payment is made. In addition, most states have statutes, regulations, or professional codes that restrict a physician from accepting various kinds of remuneration in exchange for making referrals. These laws vary from state to state and have seldom been interpreted by the courts or regulatory agencies. In states that have enacted these statutes, we believe that regulatory authorities and state courts interpreting these statutes may regard federal law under the Anti-Kickback Statute and the Stark Law as persuasive.

We believe that our operations comply with the Anti-Kickback Statute, the Stark Law, and similar federal or state laws addressing fraud and abuse. These laws are subject to modification and changes in interpretation, and are enforced by authorities vested with broad discretion. We continually monitor developments in this area. If these laws are interpreted in a manner contrary to our interpretation or are reinterpreted or amended, or if new legislation is enacted with respect to healthcare fraud and abuse, illegal remuneration, or similar issues, we may be required to restructure our affected operations to maintain compliance with applicable law. There can be no assurances that any such restructuring will be possible or, if possible, would not have a material adverse effect on our results of operations, financial position, or cash flows.

State Regulation of our Products and Services

Laws in each of the states (and Puerto Rico) in which we operate our HMOs, PPOs and other health insurance-related services regulate our operations including: capital adequacy and other licensing requirements, policy language describing benefits, mandated benefits and processes, entry, withdrawal or re-entry into a state or market, rate increases, delivery systems, utilization review procedures, quality assurance, complaint systems, enrollment requirements, claim payments, marketing, and advertising. The HMO, PPO, and other health insurance-related products we offer are sold under licenses issued by the applicable insurance regulators.

Our licensed insurance subsidiaries are also subject to regulation under state insurance holding company and Puerto Rico regulations. These regulations generally require, among other things, prior approval and/or notice of new products, rates, benefit changes, and certain material transactions, including dividend payments, purchases or sales of assets, intercompany agreements, and the filing of various financial and operational reports.

Certain of our healthcare services businesses require a Certificate of Need, or CON, to operate in certain states. These states restrict the entry of new providers or services and the expansion of existing providers or services in their state through a CON process, which is periodically evaluated and updated as required by applicable state law.

To the extent that we require a CON or other similar approvals to expand our operations, our expansion could be adversely affected by our inability to obtain the necessary approval. To the extent laws in these CON states change, including the elimination of the CON requirement, the intangible value associated with these CONs may be impaired.

Any failure by us to manage acquisitions, divestitures and other significant transactions successfully may have a material adverse effect on our results of operations, financial position, and cash flows.

As part of our business strategy, we frequently engage in discussions with third parties regarding possible investments, acquisitions, divestitures, strategic alliances, joint ventures, and outsourcing transactions and often enter into agreements relating to such transactions in order to further our business objectives. In order to pursue our acquisition strategy successfully, we must identify suitable candidates for and successfully complete transactions, some of which may be large and complex, and manage post-closing issues such as the integration of acquired companies or employees. Integration and other risks can be more pronounced for larger and more complicated transactions, transactions outside of our core business space, or if multiple transactions are pursued simultaneously. The failure to successfully integrate acquired entities and businesses or failure to produce results consistent with the financial model used in the analysis of our transactions may cause asset write-offs, restructuring costs or other expenses and may have a material adverse effect on our results of operations, financial position, and cash flows. If we fail to identify and complete successfully transactions that further our strategic objectives, we may be required to expend resources to develop products and technology internally. In addition, from time to time, we evaluate alternatives for our businesses that do not meet our strategic, growth or profitability objectives, and we may divest or wind down such businesses. There can be no assurance that we will be able to complete any such divestiture on terms favorable to us, and the divestiture of certain businesses could result, individually or in the aggregate, in the recognition of material losses and a material adverse effect on our results of operations.

If we fail to develop and maintain satisfactory relationships with the providers of care to our members, our business may be adversely affected.

We employ or contract with physicians, hospitals and other providers to deliver health care to our members. Our products encourage or require our customers to use these contracted providers. A key component of our integrated care delivery strategy is to increase the number of providers who share medical cost risk with us or have financial incentives to deliver quality medical services in a cost-effective manner.

In any particular market, providers could refuse to contract with us, demand higher payments, or take other actions that could result in higher health care costs for us, less desirable products for customers and members or difficulty meeting regulatory or accreditation requirements. In some markets, some providers, particularly hospitals, physician specialty groups, physician/hospital organizations, or multi-specialty physician groups, may have significant market positions and negotiating power. In addition, physician or practice management companies, which aggregate physician practices for administrative efficiency and marketing leverage, may compete directly with us. If these providers refuse to contract with us, use their market position to negotiate unfavorable contracts with us or place us at a competitive disadvantage, or do not enter into contracts with us that encourage the delivery of quality medical services in a cost-effective manner, our ability to market products or to be profitable in those areas may be adversely affected.

In some situations, we have contracts with individual or groups of primary care providers for an actuarially determined, fixed fee per month to provide a basket of required medical services to our members. This type of contract is referred to as a “capitation” contract. The inability of providers to properly manage costs under these capitation arrangements can result in the financial instability of these providers and the termination of their relationship with us. In addition, payment or other disputes between a primary care provider and specialists with whom the primary care provider contracts can result in a disruption in the provision of services to our members or a reduction in the services available to our members. The financial instability or failure of a primary care provider to pay other providers for services rendered could lead those other providers to demand payment from us even though we have made our regular fixed payments to the primary provider. There can be no assurance that providers with whom we contract will properly manage the costs of services, maintain financial solvency or avoid disputes with other providers. Any of these events may have a material adverse effect on the provision of services to our members and our results of operations, financial position, and cash flows.

The success of our healthcare services businesses depends on our ability, and the ability of our affiliated physician-owned professional groups and management services organizations, to recruit, hire, acquire, contract with, and retain physicians, nurses and other medical professionals who are experienced in providing care services to older adults. The market to acquire or manage physician practices, and to employ or contract with individual physicians, nurses and other medical professionals is, and is expected to remain, highly competitive, and the performance of our healthcare services businesses may be adversely impacted if we, and our affiliated physician-owned professional groups and management services organizations, are unable to attract, maintain satisfactory relationships with, and retain physicians, nurses and other medical professionals, or if these businesses are unable to retain patients following the departure of a physician, nurses or other medical professional. In addition, our healthcare services businesses contract with competitors of our health benefits businesses, and these businesses could be materially impacted if they are unable to maintain relationships with these companies, or fail to adequately negotiate the terms of their contracts with these third-party payers, including the price and other terms of fixed fee (or capitated) agreements under which our primary care business assumes the risk that the actual cost of a basket of services provided to a patient exceeds the reimbursement provided by the health plan third-party payers.

We face significant competition in attracting and retaining talented employees. Further, managing succession for, and retention of, key executives is critical to our success, and our failure to do so could adversely affect our businesses, operating results and/or future performance.

Our success depends on our ability to attract, develop and retain qualified employees and executives, including those with diverse backgrounds, experiences and skill sets, to operate and expand our business. We face intense competition for qualified employees, and there can be no assurance that we will be able to attract and retain such employees or that such competition among potential employers will not result in increasing salaries. In addition, while we have development and succession plans in place for our key employees and executives, these plans do not guarantee the services of our key employees and executives will continue to be available to us. If we are unable to attract, develop, retain and effectively manage the development and succession plans for key employees and executives, our business, results of operations and future performance could be adversely affected.

Our pharmacy business is highly competitive and subjects us to regulations and distribution and supply chain risks in addition to those we face with our core health benefits businesses.

Our in-house dispensing pharmacy business competes with locally owned drugstores, retail drugstore chains, supermarkets, discount retailers, membership clubs, internet companies and other mail-order and long-term care pharmacies.

Our pharmacy business also subjects us to extensive federal, state, and local regulation. The practice of pharmacy is generally regulated at the state level by state boards of pharmacy. Many of the states where we deliver pharmaceuticals, including controlled substances, have laws and regulations that require out-of-state mail-order pharmacies to register with that state’s board of pharmacy. Federal agencies further regulate our pharmacy operations, requiring registration with the U.S. Drug Enforcement Administration and individual state controlled substance authorities in order to dispense controlled substances. In addition, the FDA inspects facilities in connection with procedures to effect recalls of prescription drugs. The Federal Trade Commission also has requirements for mail-order sellers of goods. The U.S. Postal Service, or USPS, has statutory authority to restrict the transmission of drugs and medicines through the mail to a degree that may have an adverse effect on our mail-order operations. The USPS historically has exercised this statutory authority only with respect to controlled substances. If the USPS restricts our ability to deliver drugs through the mail, alternative means of delivery could be significantly more expensive. The U.S. Department of Transportation has regulatory authority to impose restrictions on drugs inserted in the stream of commerce. These regulations generally do not apply to the USPS and its operations. In addition, we are subject to CMS rules regarding the administration of our PDP plans and intercompany pricing between our PDP plans and our pharmacy business.

We are also subject to risks inherent in the packaging and distribution of pharmaceuticals and other health care products, including the application of state laws and regulations related to the operation of internet and mail-order pharmacies, violations of which could expose us to civil and criminal penalties, and manufacturing, distribution or other supply chain disruptions (including disruptions that occur as a result of catastrophes, including acts of terrorism, public health emergencies, epidemics or pandemics (such as COVID-19), or natural disasters (such as hurricanes and earthquakes) which could occur more frequently or with more intense effects as a result of the impacts of global climate change), each of which could impact the availability or cost of supplying of such products.

Changes in the prescription drug industry pricing benchmarks may adversely affect our financial performance.

Contracts in the prescription drug industry generally use certain published benchmarks to establish pricing for prescription drugs. These benchmarks include average wholesale price, which is referred to as “AWP,” average selling price, which is referred to as “ASP,” and wholesale acquisition cost. It is uncertain whether payors, pharmacy providers, pharmacy benefit managers, or PBMs, and others in the prescription drug industry will continue to utilize AWP as it has previously been calculated, or whether other pricing benchmarks will be adopted for establishing prices within the industry. Legislation may lead to changes in the pricing for Medicare and Medicaid programs. Regulators have conducted investigations into the use of AWP for federal program payment, and whether the use of AWP has inflated drug expenditures by the Medicare and Medicaid programs. Federal and state proposals have sought to change the basis for calculating payment of certain drugs by the Medicare and Medicaid programs. Adoption of ASP in lieu of AWP as the measure for determining payment by Medicare or Medicaid programs for the drugs sold in our in-house dispensing pharmacy business may reduce the revenues and gross margins of this business which may result in a material adverse effect on our results of operations, financial position, and cash flows.

Our ability to obtain funds from certain of our licensed subsidiaries is restricted by state insurance regulations.

Because we operate as a holding company, we are dependent upon dividends and administrative expense reimbursements from our subsidiaries to fund the obligations of Humana Inc., our parent company. Certain of our insurance subsidiaries operate in states that regulate the payment of dividends, loans, administrative expense reimbursements or other cash transfers to Humana Inc., and require minimum levels of equity as well as limit investments to approved securities. The amount of dividends that may be paid to Humana Inc. by these insurance subsidiaries, without prior approval by state regulatory authorities, or ordinary dividends, is limited based on the entity's level of statutory income and statutory capital and surplus. In most states, prior notification is provided before paying a dividend even if approval is not required. Actual dividends paid may vary due to consideration of excess statutory capital and surplus and expected future surplus requirements related to, for example, premium volume and product mix. Dividends from our non-insurance companies such as in our CenterWell segment are generally not restricted by Departments of Insurance. In the event that we are unable to provide sufficient capital to fund the obligations of Humana Inc., our results of operations, financial position, and cash flows may be materially adversely affected.

Downgrades in our debt ratings, should they occur, may adversely affect our business, results of operations, and financial condition.

Claims paying ability, financial strength, and debt ratings by recognized rating organizations are an increasingly important factor in establishing the competitive position of insurance companies. Ratings information is broadly disseminated and generally used throughout the industry. Historically, rating agencies take action to lower ratings due to, among other things, perceived concerns about liquidity or solvency, the competitive environment in the insurance industry, the inherent uncertainty in determining reserves for future claims, the outcome of pending litigation and regulatory investigations, and possible changes in the methodology or criteria applied by the rating agencies. Each of the rating agencies reviews its ratings periodically and there can be no assurance that current ratings will be maintained in the future. Our ratings reflect each rating agency’s opinion of our financial strength, operating performance, and ability to meet our debt obligations or obligations to policyholders, but are not evaluations directed toward the protection of investors in our common stock and should not be relied upon as such.

We believe that certain of our customers place importance on our claims paying ability, financial strength, and debt ratings, and we may lose customers and compete less successfully if our ratings were to be downgraded. In addition, our credit ratings impact our ability to obtain future borrowings and investment capital on favorable terms. If our credit ratings were to be lowered, our cost of borrowing likely would increase, our sales and earnings could decrease, and our results of operations, financial position, and cash flows may be materially adversely affected.

Volatility or disruption in the securities and credit markets, including changes in interest rates, may significantly and adversely affect the value of our investment portfolio and the investment income that we derive from this portfolio.

Ongoing volatility or disruption in the securities and credit markets, including changes in interest rates, may significantly and adversely affect the value of our significant investment portfolio and the investment income that we derive from this portfolio. We evaluate our investment securities for impairment on a quarterly basis. This review is subjective and requires a high degree of judgment. For the purpose of determining gross realized gains and losses, the cost of investment securities sold is based upon specific identification. For debt securities held, we recognize an impairment loss in income when the fair value of the debt security is less than the carrying value and we have the intent to sell the debt security or it is more likely than not that we will be required to sell the debt security before recovery of our amortized cost basis, or if a credit loss has occurred. When we do not intend to sell or are not required to sell a security in an unrealized loss position, potential credit related impairments are considered using a variety of factors, including the extent to which the fair value has been less than cost, adverse conditions specifically related to the industry, geographic area or financial condition of the issuer or underlying collateral of a security; payment structure of the security; changes in credit rating of the security by the rating agencies; the volatility of the fair value changes; and changes in fair value of the security after the balance sheet date. For debt securities, we take into account expectations of relevant market and economic data. We continuously review our investment portfolios and there is a continuing risk that declines in fair value may occur and additional material realized losses from sales or credit related impairments may be recorded in future periods.

We believe our cash balances, investment securities, operating cash flows, and funds available under our credit agreement or from other public or private financing sources, taken together, provide adequate resources to fund ongoing operating and regulatory requirements, acquisitions, future expansion opportunities, and capital expenditures for at least the next twelve months, as well as to refinance or repay debt, and repurchase shares. However, continuing adverse securities and credit market conditions may significantly affect the availability of credit. While there is no assurance in the current economic environment, we have no reason to believe the lenders participating in our credit agreement will not be willing and able to provide financing in accordance with the terms of the agreement.

Our access to additional credit will depend on a variety of factors such as market conditions, the general availability of credit, both to the overall market and our industry, our credit ratings and debt capacity, as well as the possibility that customers or lenders could develop a negative perception of our long or short-term financial prospects. Similarly, our access to funds could be limited if regulatory authorities or rating agencies were to take negative actions against us. If a combination of these factors were to occur, we may not be able to successfully obtain additional financing on favorable terms or at all.

Risk Management and Strategy

In the ordinary course of our business, we process, store and transmit large amounts of data, and rely on third-party service providers to do the same, including sensitive personal information as well as proprietary or confidential information relating to our business or a third-party with which we do business. The protection of information and business processes is an integrated component in our overall risk management program, and reflected in our Code of Ethics, security standards, and privacy policies. We employ processes to safeguard information and protect our customers’ data, including by deploying both proactive and defensive practices against the evolving cyber threat landscape. Examples of these processes include:

a. Employing a qualified Chief Information Security Officer.

b. Maintaining tools to identify malicious cyber activity.

c. Monitoring risks posed by threat actors, including through partnerships with industry groups and government agencies.

d. Providing annual cybersecurity training to our associates.

e. Testing our associates’ knowledge through internal phishing simulations.

f. Engaging an independent third-party audit firm to perform an Annual Service Organizational Controls (SOC) 2 audit of enterprise claims platforms.

g. Reporting data breaches, as required by law, to the U.S. Department of Health and Human Services (HHS), Office for Civil Rights (OCR), and various state agencies; our reports are publicly available, free of charge, and can be obtained through the OCR Portal at https://ocrportal.hhs.gov/ocr/breach.

h. Maintaining a program to identify cybersecurity risks associated with certain third-party vendors, which is one component of an overall vendor risk management program.

We also enhance our information technology infrastructure and security protocols to assess, identify, protect against, and manage material risks from cybersecurity threats following a risk-based approach. In addition, we conduct cybersecurity risk assessments at least annually, and periodically engage an independent auditor or other external assessors to aid in pro-active risk identification, prevention, detection, mitigation, and remediation. Our efforts to manage against cybersecurity threats are further guided by Federal and state laws, as well as contractual commitments with third parties, which regulate our collection, use and disclosure of confidential information such as protected health information and personally identifiable information.

Although we have been subject to breaches of our information technology systems, including breaches of the information technology systems of third-party service providers, the impact of such attacks has not been material to our business strategy, operations or results of operations, financial position, or cash flows through December 31, 2024. We do not believe that cybersecurity threats resulting from any previous cybersecurity incidents of which we are aware are reasonably likely to materially affect the Company. For additional information on the risks we face from cybersecurity threats, please refer to Part I, Item 1A, "Risk Factors" of this Form 10-K.

Governance

As part of its overall responsibility for oversight of our enterprise risk management, our Board of Directors reviews material risks to our Company, including risks from cybersecurity threats. The Board has designated our Audit Committee and Technology Committee with joint oversight over our information technology internal controls, cybersecurity, business continuity and disaster recovery programs.

Management is responsible for designing and implementing our governance framework and controls for managing our material risks from cybersecurity threats, under the oversight of our Board of Directors. Our Chief Information Security Officer is responsible for assessing and managing identified cybersecurity risks, evaluating and remediating cybersecurity incidents, and sharing information directly with the Audit Committee and Technology Committee, or full Board of Directors, when appropriate. Our Chief Information Security Officer reports to our

Chief Information Officer, who is in turn responsible for the management of Humana’s data and information technology risks more generally. Our Chief Information Officer is a senior executive with more than two decades of experience leading technology teams in large, regulated industries. Our Chief Information Security Officer is an experienced cybersecurity executive and leader in the field, with many years of relevant experience working in highly regulated industries.

Among our cybersecurity and risk teams, we utilize established governance mechanisms to enable a transparent and holistic approach to cybersecurity risk management, and the evaluation and remediation of cybersecurity incidents. These processes enable cross-functional engagement from our enterprise information protection, enterprise risk management, enterprise compliance, information technology, legal, privacy, and data governance teams.

As a key component of this governance framework, the Audit Committee and Technology Committee also receive regular updates regarding our cybersecurity program and cybersecurity incidents from our Chief Information Security Officer.

Our principal executive office is located in the Humana Building, 500 West Main Street, Louisville, Kentucky 40202. In addition to the headquarters in Louisville, Kentucky, we maintain other principal operating facilities used for customer service, enrollment, and/or claims processing and certain other corporate functions in Louisville, Kentucky; Green Bay, Wisconsin; Tampa, Florida; Cincinnati, Ohio; San Antonio, Texas; San Juan, Puerto Rico; and Austin, Texas.

We owned or leased numerous medical centers and administrative offices at December 31, 2024. The medical centers we operate are primarily located in Florida and Texas, including full-service, multi-specialty medical centers staffed by primary care providers and medical specialists. Of these medical centers, approximately 378 of these facilities are leased or subleased to our contracted providers to operate.

We are party to a variety of legal actions in the ordinary course of business, certain of which may be styled as class-action lawsuits. Among other matters, this litigation may include employment matters, claims of medical malpractice, bad faith, nonacceptance or termination of providers, anticompetitive practices, improper rate setting, provider contract rate disputes, qui tam litigation brought by individuals seeking to sue on behalf of the government, failure to disclose network discounts and various other provider arrangements, general contractual matters, intellectual property matters, and challenges to subrogation practices. For a discussion of our material legal actions, including those not in the ordinary course of business, see “Legal Proceedings and Certain Regulatory Matters” in Note 17 to the audited Consolidated Financial Statements included in Item 8. – Financial Statements and Supplementary Data. We cannot predict the outcome of these suits with certainty.

For discussion of 2022 items and year-over-year comparisons between 2023 and 2022 that are not included in this 2024 Form 10-K, refer to "Item 7. – Management Discussion and Analysis of Financial Condition and Results of Operations" found in our Form 10-K for the year ended December 31, 2023, that was filed with the Securities and Exchange Commission on February 15, 2024.

Executive Overview

General

Humana Inc., headquartered in Louisville, Kentucky, is committed to putting health first – for our teammates, our customers, and our company. Through our Humana insurance services, and our CenterWell health care services, we make it easier for the millions of people we serve to achieve their best health – delivering the care and service they need, when they need it. These efforts are leading to a better quality of life for people with Medicare, Medicaid, families, individuals, military service personnel, and communities at large.

Our industry relies on two key statistics to measure performance. The benefit ratio, which is computed by taking total benefits expense as a percentage of premiums revenue, represents a statistic used to measure underwriting profitability. The operating cost ratio, which is computed by taking total operating costs, excluding depreciation and amortization, as a percentage of total revenue less investment income, represents a statistic used to measure administrative spending efficiency.

Employer Group Commercial Medical Products Business Exit

In February 2023, we announced our planned exit from the Employer Group Commercial Medical Products business, which includes all fully insured, self-funded and Federal Employee Health Benefit medical plans, as well as associated wellness and rewards programs. No other Humana health plan offerings are materially affected. Following a strategic review, we determined the Employer Group Commercial Medical Products business was no longer positioned to sustainably meet the needs of commercial members over the long term or support our long-term strategic plans. We anticipate the exit of this line of business to be finalized in the first half of 2025.

Value Creation Initiatives and Impairment Charges

In order to create capacity to fund growth and investment in our Medicare Advantage business and further expansion of our healthcare services capabilities beginning in 2022, we committed to drive additional value for the enterprise through cost saving, productivity initiatives, and value acceleration from previous investments. As a result of these initiatives, we recorded charges of $281 million and $436 million in 2024 and 2023, respectively, primarily within operating costs in the consolidated statements of income.

The value creation initiative charges primarily relate to $256 million and $237 million in asset impairments in 2024 and 2023, respectively, as well as $25 million and $199 million in severance charges in connection with workforce optimization in 2024 and 2023, respectively.

In addition, we recorded impairment charges of $200 million, relating to indefinite-lived intangible assets, in 2024 and $91 million, including $55 million relating to indefinite-lived intangible assets, in 2023. The indefinite-lived intangible asset impairment charges were included within operating costs in our consolidated statements of income with the remaining impairment charges included within investment income.

Further, we recorded severance charges of $70 million in 2023 within operating costs in our consolidated statement of income as a result of our exit from the Employer Group Commercial Medical Products business.

COVID-19

The emergence and spread of the novel coronavirus, or COVID-19, beginning in the first quarter of 2020 has impacted our business. Initially during periods of increased incidences of COVID-19, a reduction in non-COVID-19 hospital admissions for non-emergent and elective medical care resulted in lower overall healthcare system utilization. At the same time, COVID-19 treatment and testing costs increased utilization. During 2022, we experienced lower overall utilization of the healthcare system than anticipated, as the reduction in COVID-19 utilization following the increased incidence associated with the Omicron variant outpaced the increase in non-COVID-19 utilization.

The COVID-19 National Emergency declared in 2020 was terminated on April 10, 2023 and the Public Health Emergency expired on May 11, 2023.

Business Segments

Our two reportable segments, Insurance and CenterWell, are based on a combination of the type of health plan customer and adjacent businesses centered on well-being solutions for our health plans and other customers, as described below. Our Chief Executive Officer, the Chief Operating Decision Maker, utilizes these segment groupings and results of each segment, measured by income (loss) from operations, to assess performance and allocate resources primarily during our annual budget process and periodic forecast updates. For segment financial information, refer to Note 18 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

The Insurance segment consists of Medicare benefits, marketed to individuals or directly via group Medicare accounts, as well as our contract with CMS to administer the Limited Income Newly Eligible Transition, or LI-NET, prescription drug plan program and contracts with various states to provide Medicaid, dual eligible demonstration, and Long-Term Support Services benefits, which we refer to collectively as our state-based contracts. This segment also includes products consisting of employer group commercial fully-insured medical and specialty health insurance benefits marketed to individuals and employer groups, including dental, vision, and other supplemental health benefits, as well as administrative services only, or ASO. In addition, our Insurance segment includes our Military services business, primarily our T-2017 East Region contract, as well as the operations of our PBM business.

The CenterWell segment includes our pharmacy, primary care, and home solutions operations. The segment also includes our strategic partnerships with WCAS to develop and operate senior-focused, payor-agnostic, primary care centers, as well as our minority ownership interest in hospice operations. Services offered by this segment are designed to enhance the overall healthcare experience. These services may lead to lower utilization associated with improved member health and/or lower drug costs.

Transactions between reportable segments primarily consist of sales of products and services rendered by our CenterWell segment, primarily pharmacy, primary care, and home solutions, to our Insurance segment customers. Intersegment sales and expenses are recorded primarily at fair value and eliminated in consolidation. Members served by our segments often use the same provider networks, enabling us in some instances to obtain more favorable contract terms with providers. Our segments also share indirect costs and assets. As a result, the profitability of each segment is interdependent. We allocate most operating expenses to our segments. Assets and certain corporate income and expenses are not allocated to the segments, including the portion of investment income not supporting segment operations, interest expense on corporate debt, and certain other corporate expenses. These items are managed at a corporate level. These corporate amounts are reported separately from our reportable segments and are included with intersegment eliminations.

Seasonality

One of the product offerings of our Insurance segment is Medicare stand-alone prescription drug plans, or PDP, under the Medicare Part D program. Our quarterly Insurance segment earnings and operating cash flows are impacted by the Medicare Part D benefit design and changes in the composition of our membership. The Medicare

Part D benefit design results in coverage that varies as a member’s cumulative out-of-pocket costs pass through successive stages of a member’s plan period, which begins annually on January 1 for renewals. These plan designs generally result in us sharing a greater portion of the responsibility for total prescription drug costs in the early stages and less in the latter stages. As a result, the PDP benefit ratio generally decreases as the year progresses. In addition, the number of low income senior members as well as year-over-year changes in the mix of membership in our stand-alone PDP products affects the quarterly benefit ratio pattern. Beginning in 2025, changes to Part D under the Inflation Reduction Act are expected to increase risk-adjusted direct subsidies and cap members' out-of-pocket costs and as a result significantly impact seasonality and cost trends.

The Insurance segment also experiences seasonality in the commercial fully-insured product offering. The effect on the Insurance segment benefit ratio is opposite of the Medicare stand-alone PDP impact, with the benefit ratio increasing as fully-insured members progress through their annual deductible and maximum out-of-pocket expenses. The Employer Group Commercial Fully-Insured business increased the Insurance segment benefit ratio by 10 basis points for the year ended December 31, 2024 and did not impact the Insurance segment benefit ratio for the year ended December 31, 2023.

The Insurance segment also experiences seasonality in the operating cost ratio as a result of costs incurred in the second half of the year associated with the Medicare marketing season. The Insurance segment may experience adverse impacts in the operating cost ratio as a result of our Employer Group Commercial Medical Products exit. The Employer Group Commercial Fully-Insured business did not impact the Insurance segment operating cost ratio for the year-ended December 31, 2024 and increased the Insurance segment operating cost ratio by 30 basis points for the year ended December 31, 2023.

Highlights

• Our strategy offers our members affordable health care combined with a positive consumer experience in growing markets. At the core of this strategy is our integrated care delivery model, which unites quality care, high member engagement, and sophisticated data analytics. Our approach to primary, physician-directed care for our members aims to provide quality care that is consistent, integrated, cost-effective, and member-focused, provided by both employed physicians and physicians with network contract arrangements. The model is designed to improve health outcomes and affordability for individuals and for the health system as a whole, while offering our members a simple, seamless healthcare experience. We believe this strategy is positioning us for long-term growth in both membership and earnings. We offer providers a continuum of opportunities to increase the integration of care and offer assistance to providers in transitioning from a fee-for-service to a value-based arrangement. These include performance bonuses, shared savings and shared risk relationships. At December 31, 2024, approximately 3,994,300 members, or 71%, of our individual Medicare Advantage members were in value-based relationships under our integrated care delivery model, as compared to 3,764,300 members, or 70%, at December 31, 2023.
• Net income attributable to Humana was $1.2 billion, or $9.98 per diluted common share, and $2.5 billion, or $20.00 per diluted common share, in 2024 and 2023, respectively. This comparison was significantly impacted by put/call valuation adjustments associated with non-consolidating minority interest investments, charges associated with value creation initiatives, transaction and integration costs, impairment charges and an accrual related to certain anticipated litigation expenses. The impact of these adjustments to our consolidated income before income taxes and equity in net earnings and diluted earnings per common share was as follows for the 2024 and 2023 periods:

Regulatory Environment

We are and will continue to be regularly subject to new laws and regulations, changes to existing laws and regulations, and judicial determinations that impact the interpretation and applicability of those laws and regulations. The Health Care Reform Law, the Families First Act, the CARES Act, and the Inflation Reduction Act, and related regulations, are examples of laws which have enacted significant reforms to various aspects of the U.S. health insurance industry, including, among others, mandated coverage requirements, mandated benefits and guarantee issuance associated with insurance products, rebates to policyholders based on minimum benefit ratios, adjustments to Medicare Advantage premiums, the establishment of federally facilitated or state-based exchanges coupled with programs designed to spread risk among insurers, and the introduction of plan designs based on set actuarial values, and changes to the Part D prescription drug benefit design.

It is reasonably possible that these laws and regulations, as well as other current or future legislative, judicial or regulatory changes including restrictions on our ability to manage our provider network, manage and sell our products, or otherwise operate our business, or restrictions on profitability, including reviews by regulatory bodies that may compare our Medicare Advantage profitability to our non-Medicare Advantage business profitability, or compare the profitability of various products within our Medicare Advantage business, and require that they remain within certain ranges of each other, increases in member benefits or changes to member eligibility criteria without corresponding increases in premium payments to us, further restrictions on service arrangements and fee payments between intercompany or vertically-integrated assets, increases in regulation of our prescription drug benefit businesses, or changes to the Part D prescription drug benefit design (and uncertainty arising from the implementation of these changes) in the aggregate may have a material adverse effect on our results of operations (including restricting revenue, enrollment and premium growth in certain products and market segments, restricting our ability to expand into new markets, increasing our medical and operating costs, further lowering our Medicare payment rates and increasing our expenses associated with assessments); our financial position (including our ability to maintain the value of our goodwill); and our cash flows.

We intend for the discussion of our financial condition and results of operations that follows to assist in the understanding of our financial statements and related changes in certain key items in those financial statements from year to year, including the primary factors that accounted for those changes. Transactions between reportable segments primarily consist of sales of products and services rendered by our CenterWell segment, primarily pharmacy, primary care, and home solutions, to our Insurance segment customers and are described in Note 18 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Comparison of Results of Operations for 2024 and 2023

The following discussion primarily details our results of operations for the year ended December 31, 2024, or the 2024 period, and the year ended December 31, 2023, or the 2023 period.

Consolidated

(dollars in millions, except per common share results)

(a) Represents total benefits expense as a percentage of premiums revenue.

(b) Represents total operating costs, excluding depreciation and amortization, as a percentage of total revenues less investment income.

Premiums Revenue

Consolidated premiums revenue increased $10.8 billion, or 10.7%, from $101.3 billion in the 2023 period to $112.1 billion in the 2024 period primarily due to higher per member Medicare premiums as well as Medicare Advantage and state-based contracts membership growth. These factors were partially offset by the continued decline in stand-alone PDP membership, as well as a decline in membership in our group commercial medical business as a result of our decision to exit the business.

Services Revenue

Consolidated services revenue increased $0.4 billion, or 9.9%, from $4.0 billion in the 2023 period to $4.4 billion in the 2024 period primarily due to higher revenues associated with growth in the primary care business, partially offset by the impact of the v28 risk model revision.

Investment Income

Investment income increased $0.16 billion, or 14.7%, from $1.07 billion in the 2023 period to $1.23 billion in the 2024 period primarily due to an increase in interest income on our debt securities.

Benefits Expense

Consolidated benefits expense increased $12.3 billion, or 13.9%, from $88.4 billion in the 2023 period to $100.7 billion in the 2024 period. The consolidated benefit ratio increased 250 basis points from 87.3% in the 2023 period to 89.8% in the 2024 period primarily due to the continued impact of elevated Medicare Advantage and state-based contracts medical cost trends in the 2024 period as well as lower favorable prior period medical claims reserve development. These factors were partially offset by the impact of the pricing and benefit design of our 2024 Medicare Advantage products, which included a reduction in member benefits in response to the net impact of the 2024 final rate notice and the initial emergence of increased medical cost trends in 2023. Further, the year-over-year comparison continues to reflect a shift in line of business mix, with growth in Medicare Advantage and state-based contracts and other membership, which can carry a higher benefit ratio.

Consolidated benefits expense included $701 million of favorable prior-period medical claims reserve development in the 2024 period and $872 million of favorable prior-period medical claims reserve development in the 2023 period. Prior-period medical claims reserve development decreased the consolidated benefit ratio by approximately 60 basis points in the 2024 period and decreased the consolidated benefit ratio by approximately 90 basis points in the 2023 period.

Operating Costs

Our segments incur both direct and shared indirect operating costs. We allocate the indirect costs shared by the segments primarily as a function of revenues. As a result, the profitability of each segment is interdependent.

Consolidated operating costs increased $0.5 billion, or 3.9%, from $13.2 billion in the 2023 period to $13.7 billion in the 2024 period. The consolidated operating cost ratio decreased 70 basis points from 12.5% in the 2023 period to 11.8% in the 2024 period. The ratio decrease was primarily due to scale efficiencies associated with growth in individual Medicare Advantage membership, administrative cost efficiencies resulting from our value creation initiatives, a lesser impact of commission expense for brokers in the 2024 period compared to the 2023 period as a result of significant individual Medicare Advantage membership growth in 2023, a lesser impact from charges related to value creation initiatives in the 2024 period compared to the 2023 period, as well as the impact of the accrued charge related to certain anticipated litigation expenses in the 2023 period. These factors were partially offset by significantly reduced compensation accruals in the 2023 period related to the annual incentive plan offered to employees across all levels of the company as our 2023 performance was negatively impacted by higher-than-anticipated Medicare Advantage utilization trends, as well as higher impairment costs in the 2024 period.

Depreciation and Amortization

Depreciation and amortization increased $60 million, or 7.7%, from $779 million in the 2023 period to $839 million in the 2024 period primarily due to capital expenditures.

Interest Expense

Interest expense increased $167 million, or 33.9%, from $493 million in the 2023 period to $660 million in the 2024 period primarily due to an increase in interest rates and higher average debt balances.

Income Taxes

Our effective tax rate was 25.5% and 25.2% for the 2024 period and 2023 period, respectively. The year-over-year increase in the effective income tax rate is primarily due to a change in the mix of current year earnings between our Insurance segment and our CenterWell health services segment, as our CenterWell health services segment is subject to a higher effective tax rate than our Insurance segment. For a complete reconciliation of the federal statutory rate to the effective tax rate, refer to Note 12 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Insurance Segment

(in millions)

Income from operations

Insurance segment income from operations decreased $1.4 billion, or 51.4%, from $2.6 billion in the 2023 period to $1.3 billion in the 2024 period primarily due to the same factors impacting the segment's higher benefit ratio partially offset by the impact of the lower operating cost ratio as more fully described below.

Enrollment

Individual Medicare Advantage membership increased 252,900 members, or 4.7%, from 5,408,900 members as of December 31, 2023 to 5,661,800 members as of December 31, 2024 primarily due to membership additions associated with the 2024 Annual Election Period, or AEP. Individual Medicare Advantage membership includes 937,100 D-SNP members as of December 31, 2024, a net increase of 65,800 D-SNP members, or 7.6%, from 871,300 members as of December 31, 2023. For the full year 2025, we anticipate net membership decline in our individual Medicare Advantage offerings of approximately 550,000 members.

Group Medicare Advantage membership increased 36,100 members, or 7.1%, from 509,600 members as of December 31, 2023 to 545,700 members as of December 31, 2024 primarily due to growth in small and medium group accounts. For the full year 2025, we anticipate net membership growth in our group Medicare Advantage offerings to be relatively flat.

Medicare stand-alone PDP membership decreased 560,900 members, or 19.7%, from 2,849,100 members as of December 31, 2023 to 2,288,200 members as of December 31, 2024 primarily due to continued intensified competition for Medicare stand-alone PDP offerings. For the full year 2025, we anticipate net membership growth in our Medicare stand-alone PDP offerings of approximately 200,000 members.

State-based contracts and other membership increased 231,100 members, or 18.8%, from 1,228,800 members as of December 31, 2023 to 1,459,900 members as of December 31, 2024 reflecting the impact of membership additions associated with the implementation of new contracts partially offset with membership loss as a result of the public health of emergency unwind. For the full year 2025, we anticipate net membership growth in our state-based contracts of approximately 175,000 to 250,000 members.

Specialty membership decreased 306,300 members, or 6.3%, from 4,868,300 members as of December 31, 2023 to 4,562,000 members as of December 31, 2024 primarily due to non-renewal of dental and vision plans as a result of exit from the Employer Group Commercial Medical Products business.

The decrease in commercial fully-insured and ASO membership as of December 31, 2024 compared to December 31, 2023 is due to our exit of the Employer Group Commercial Medical Products business.

Premiums revenue

Insurance segment premiums revenue increased $10.8 billion, or 10.7%, from $101.3 billion in the 2023 period to $112.1 billion in the 2024 period primarily due to higher per member Medicare premiums as well as Medicare Advantage and state-based contracts membership growth. These factors were partially offset by the continued decline in stand-alone PDP membership, as well as a decline in membership in our group commercial medical business as a result of our decision to exit the business.

Services revenue

Insurance segment services revenue decreased $34 million, or 3.4%, from $1.0 billion in the 2023 period to $966 million in the 2024 period.

Benefits expense

The Insurance segment benefit ratio increased 240 basis points from 88.0% in the 2023 period to 90.4% in the 2024 period primarily due to the continued impact of elevated Medicare Advantage and state-based contracts medical cost trends in the 2024 period as well as lower favorable prior period medical claims reserve development. These factors were partially offset by the impact of the pricing and benefit design of our 2024 Medicare Advantage products, which included a reduction in member benefits in response to the net impact of the 2024 final rate notice and the initial emergence of increased medical cost trends in 2023. Further, the year-over-year comparison continues to reflect a shift in line of business mix, with growth in Medicare Advantage and state-based contracts and other membership, which can carry a higher benefit ratio.

The Insurance segment benefits expense included $701 million of favorable prior-period medical claims reserve development in the 2024 period and $872 million of favorable prior-period medical claims reserve development in the 2023 period. Prior-period medical claims reserve development decreased the Insurance segment benefit ratio by approximately 60 basis points in the 2024 period and decreased the Insurance segment benefit ratio by approximately 90 basis points in the 2023 period.

Operating costs

The Insurance segment operating cost ratio decreased 100 basis points from 10.2% in the 2023 period to 9.2% in the 2024 period primarily due to scale efficiencies associated with growth in individual Medicare Advantage membership, administrative cost efficiencies resulting from our value creation initiatives, a lesser impact of commission expense for brokers in the 2024 period compared to the 2023 period as a result of significant individual Medicare Advantage membership growth in 2023, as well as the impact of the accrued charge related to certain anticipated litigation expenses included in the 2023 period. These factors were partially offset by significantly reduced compensation accruals in the 2023 period.

CenterWell Segment

(in millions)

Income from operations

CenterWell income from operations decreased $0.1 billion, or 5.3%, from $1.4 billion in the 2023 period to $1.3 billion in the 2024 period primarily due to the same factors impacting the segment's higher operating cost ratio as more fully described below.

Services revenue

CenterWell services revenue increased $0.4 billion, or 14.2%, from $3.0 billion in the 2023 period to $3.5 billion in the 2024 period primarily due to higher revenues associated with growth in the primary care business, partially offset by the impact of the v28 risk model revision.

Intersegment revenues

CenterWell intersegment revenues increased $1.1 billion, or 7.1%, from $15.4 billion in the 2023 period to $16.5 billion in the 2024 period primarily due to greater intersegment revenues associated with the home solutions business in the 2024 period as compared to the 2023 period as a result of the expansion of services to Humana members under value-based contracts, an increase in pharmacy solutions revenues resulting from growth in the specialty pharmacy business, driven by increased penetration of Humana health plan members, as well as payor agnostic consumers, and higher revenues associated with growth in the primary care business, partially offset by the impact of the v28 risk model revision.

Operating costs

The CenterWell segment operating cost ratio increased 100 basis points from 91.2% in the 2023 period to 92.2% in the 2024 period primarily due to the unfavorable impact of the v28 risk model revision to the primary care business and the impact of significantly reduced compensation accruals in the 2023 period, partially offset by administrative cost efficiencies resulting from our value creation initiatives and positive prior-period medical claims reserve development within the Primary Care Organization.

Liquidity

Historically, our primary sources of cash have included receipts of premiums, services revenue, and investment and other income, as well as proceeds from the sale or maturity of our investment securities, and borrowings. Our primary uses of cash historically have included disbursements for claims payments, operating costs, interest on borrowings, taxes, purchases of investment securities, acquisitions, capital expenditures, repayments on borrowings, dividends, and share repurchases. As premiums generally are collected in advance of claim payments by a period of up to several months, our business normally should produce positive cash flows during periods of increasing premiums and enrollment. Conversely, cash flows would be negatively impacted during periods of decreasing premiums and enrollment. From period to period, our cash flows may also be affected by the timing of working capital items including premiums receivable, benefits payable, and other receivables and payables. Our cash flows are impacted by the timing of payments to and receipts from CMS associated with Medicare Part D subsidies for which we do not assume risk. The use of cash flows may be limited by regulatory requirements of state departments of insurance (or comparable state regulators) which require, among other items, that our regulated subsidiaries maintain minimum levels of capital and seek approval before paying dividends from the subsidiaries to the parent. Our use of cash flows derived from our non-insurance subsidiaries, such as in our CenterWell segment, is generally not restricted by state departments of insurance (or comparable state regulators).

For additional information on our liquidity risk, please refer to Part I, Item 1A, "Risk Factors" of this Form 10-K.

Cash and cash equivalents decreased to $2.2 billion at December 31, 2024 from $4.7 billion at December 31, 2023. The change in cash and cash equivalents for the years ended December 31, 2024, 2023 and 2022 is summarized as follows:

(in millions)

Cash Flow from Operating Activities

Cash flows provided by operations of $3.0 billion in the 2024 period decreased $1.0 billion from cash flows provided by operations of $4.0 billion in the 2023 period primarily due to lower earnings in the 2024 period compared to the 2023 period, partially offset by the favorable impact of working capital changes.

The most significant drivers of changes in our working capital are typically the timing of payments of benefits expense and receipts for premiums. Benefits expense includes claim payments, capitation payments, pharmacy costs net of rebates, allocations of certain centralized expenses and various other costs incurred to provide health insurance coverage to members, as well as estimates of future payments to hospitals and others for medical care and other supplemental benefits provided on or prior to the balance sheet date. For additional information regarding our benefits payable and benefits expense recognition, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

The detail of total net receivables was as follows at December 31, 2024, 2023 and 2022:

(in millions)

The changes in Medicare receivables for both the 2024 period and the 2023 period reflect individual Medicare Advantage membership growth and the typical pattern caused by the timing of accruals and related collections associated with the CMS risk-adjustment model. The increase in State-based contracts receivables for the 2024 and 2023 periods is primarily related to expansion to various states.

Cash Flow from Investing Activities

During the 2022 period, we completed the sale of a 60% interest of Gentiva Hospice to CD&R for cash proceeds of approximately $2.7 billion, net of cash disposed, including debt repayments from Gentiva Hospice to Humana of $1.9 billion. In connection with the sale we recognized a pre-tax gain, net of transaction costs, of $237 million which was reported as a gain on sale of Gentiva Hospice in the accompanying consolidated statement of income for the year ended December 31, 2022.

During the 2024, 2023 and 2022 periods, we acquired various businesses for approximately $89 million, $233 million and $337 million, respectively, net of cash and cash equivalents received.

Our ongoing capital expenditures primarily relate to our information technology initiatives, support of services in our primary care operations including medical and administrative facility improvements necessary for activities such as the provision of care to members, claims processing, billing and collections, wellness solutions, care coordination, regulatory compliance and customer service. Total net capital expenditures, excluding acquisitions, were $568 million, $794 million and $1.1 billion in the 2024, 2023 and 2022 periods, respectively.

Net purchases of investment securities were $2.2 billion, $2.5 billion and $2.3 billion in the 2024, 2023 and 2022 periods, respectively.

Cash Flow from Financing Activities

Our financing cash flows are significantly impacted by the timing of claims payments and the related receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk. Monthly prospective payments from CMS for reinsurance and low-income cost subsidies are based on assumptions submitted with our annual bid. Settlement of the reinsurance and low-income cost subsidies is based on a reconciliation made approximately 9 months after the close of each calendar year. Claim payments were higher than receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk by $1.8 billion in the 2024 period and receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk were higher than claim payments by $0.8 billion and $2 billion in the 2023 and 2022 periods, respectively. Our net receivable from CMS for subsidies and brand name prescription drug discounts was $0.5 billion at December 31, 2024 compared to a net payable of $1.3 billion at December 31, 2023.

Under our administrative services only TRICARE contract, health care costs payments for which we do not assume risk exceeded reimbursements from the federal government by $92 million in the 2024 period and reimbursements from the federal government exceeded health care costs payments for which we do not assume risk by $57 million and $25 million in the 2023 and 2022 periods, respectively.

In 2024, we entered into a securities lending program where we loan certain investment securities for short periods of time in exchange for collateral. We also entered into an uncommitted receivables purchase facility under which certain pharmaceutical rebate receivables may be sold on a non-recourse basis to a financial institution. For the year ended December 31, 2024, the securities lending program and uncommitted receivables purchase facility provided net proceeds of $418 million and $123 million, respectively.

We repaid the remaining $1.2 billion aggregate principal amount of our 0.650% senior notes due on their maturity date of August 3, 2023. We repaid the remaining $559 million aggregate principal amount of our 3.850% senior notes on their maturity date of October 1, 2024.

We entered into a commercial paper program in October 2014. Net repayments from issuance of commercial paper were $907 million in 2024 and the maximum principal amount outstanding at any one time during 2024 was $2.7 billion. Net proceeds from the issuance of commercial paper were $211 million in 2023 and the maximum principal amount outstanding at any one time during 2023 was $3.3 billion.

Acquisitions & Divestitures

For a detailed discussion regarding acquisitions and divestitures, refer to Note 3 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Liquidity Requirements

We believe our cash balances, investment securities, operating cash flows, and funds available under our credit agreement and our commercial paper program or from other public or private financing sources, taken together, provide adequate resources to fund ongoing operating and regulatory requirements, acquisitions, future expansion opportunities, and capital expenditures for at least the next twelve months, as well as to refinance or repay debt, and repurchase shares.

Adverse changes in our credit rating may increase the rate of interest we pay and may impact the amount of credit available to us in the future. Our investment-grade credit rating at December 31, 2024 was BBB according to Standard & Poor’s Rating Services, or S&P, and Baa2 according to Moody’s Investors Services, Inc., or Moody’s. A downgrade by S&P to BB+ or by Moody’s to Ba1 triggers an interest rate increase of 25 basis points with respect to $250 million of our senior notes. Successive one notch downgrades increase the interest rate an additional 25 basis points, or annual interest expense by $1 million, up to a maximum 100 basis points, or annual interest expense by $3 million.

In addition, we operate as a holding company in a highly regulated industry. Humana Inc., our parent company, is dependent upon dividends and administrative expense reimbursements from our subsidiaries, most of which are subject to regulatory restrictions. We continue to maintain significant levels of aggregate excess statutory capital and surplus in our state-regulated operating subsidiaries. Cash, cash equivalents, and short-term investments at the parent company were $0.6 billion at December 31, 2024 compared to $0.5 billion at December 31, 2023. This increase primarily reflects working capital changes, net proceeds from the issuance of senior notes and commercial paper, proceeds from the sale and maturities of investment securities, dividends from insurance subsidiaries and cash from certain non-insurance subsidiaries within our CenterWell segment partially offset by common stock repurchases, repayment of maturing senior notes, repayment of borrowings under the commercial paper program, purchases of investment securities, capital expenditures, capital contributions to certain subsidiaries, cash dividends to shareholders and acquisitions. Our use of operating cash derived from our non-insurance subsidiaries, such as our CenterWell segment, is generally not restricted by departments of insurance (or comparable state regulators). Our regulated insurance subsidiaries paid dividends to our parent company of $1.5 billion in 2024, $1.8 billion in 2023, and $1.3 billion in 2022. Subsidiary capital requirements from significant premium growth may impact the amount of regulated subsidiary dividends. Refer to our parent company financial statements and accompanying notes in Schedule I - Parent Company Financial Information. The amount of ordinary dividends that may be paid to our parent company in 2025 is approximately $1.3 billion, in the aggregate. Actual dividends paid may vary due to consideration of excess statutory capital and surplus and expected future surplus requirements related to, for example, premium volume and product mix.

Regulatory Requirements

For a detailed discussion of our regulatory requirements, including aggregate statutory capital and surplus as well as dividends paid from the subsidiaries to our parent, please refer to Note 16 to the to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Off-Balance Sheet Arrangements

As of December 31, 2024, we were not involved in any special purpose entity, or SPE, transactions. For a detailed discussion of off-balance sheet arrangements, please refer to Note 17 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements and accompanying notes, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements and accompanying notes requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We continuously evaluate our estimates and those critical accounting policies primarily related to benefits expense and revenue recognition as well as accounting for impairments related to our investment securities, goodwill, indefinite-lived and long-lived assets. These estimates are based on knowledge of current events and anticipated future events and, accordingly, actual results ultimately may differ from those estimates. We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our consolidated financial statements.

Benefits Expense Recognition

Benefits expense is recognized in the period in which services are provided and includes an estimate of the cost of services which have been incurred but not yet reported, or IBNR. Our reserving practice is to consistently recognize the actuarial best point estimate within a level of confidence required by actuarial standards. For further discussion of our reserving methodology, including our use of completion and claims per member per month trend factors to estimate IBNR, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

The completion and claims per member per month trend factors are the most significant factors impacting the IBNR estimate. The portion of IBNR estimated using completion factors for claims incurred prior to the most recent two months is generally less variable than the portion of IBNR estimated using trend factors. The following table illustrates the sensitivity of these factors assuming moderately adverse experience and the estimated potential impact on our operating results caused by reasonably likely changes in these factors based on December 31, 2024 data:

(dollars in millions)

(a) Reflects estimated potential changes in benefits payable at December 31, 2024 caused by changes in completion factors for incurred months prior to the most recent two months.

(b) Reflects estimated potential changes in benefits payable at December 31, 2024 caused by changes in annualized claims trend used for the estimation of per member per month incurred claims for the most recent two months.

(c) The factor change indicated represents the percentage point change.

The following table provides a historical perspective regarding the accrual and payment of our benefits payable. Components of the total incurred claims for each year include amounts accrued for current year estimated benefits expense as well as adjustments to prior year estimated accruals. Refer to Note 11 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K for information about incurred and paid claims development as of December 31, 2024 as well as cumulative claim frequency and the total of IBNR included within the net incurred claims amounts.

(in millions)

The following table summarizes the changes in estimate for incurred claims related to prior years attributable to our key assumptions. As previously described, our key assumptions consist of trend and completion factors estimated using an assumption of moderately adverse conditions. The amounts below represent the difference between our original estimates and the actual benefits expense ultimately incurred as determined from subsequent claim payments.

(dollars in millions)

(a) The factor change indicated represents the percentage point change.

As previously discussed, our reserving practice is to consistently recognize the actuarial best estimate of our ultimate liability for claims. Actuarial standards require the use of assumptions based on moderately adverse experience, which generally results in favorable reserve development, or reserves that are considered redundant. We experienced favorable medical claims reserve development related to prior fiscal years of $701 million in 2024, $872 million in 2023, and $415 million in 2022.

The favorable medical claims reserve development for 2024, 2023, and 2022 primarily reflects the consistent application of trend and completion factors estimated using an assumption of moderately adverse conditions.

Our favorable development for each of the years presented above is discussed further in Note 11 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

We continually adjust our historical trend and completion factor experience with our knowledge of recent events that may impact current trends and completion factors when establishing our reserves. Because our reserving practice is to consistently recognize the actuarial best point estimate using an assumption of moderately adverse conditions as required by actuarial standards, there is a reasonable possibility that variances between actual trend and completion factors and those assumed in our December 31, 2024 estimates would fall towards the middle of the ranges previously presented in our sensitivity table.

Revenue Recognition

We generally establish one-year commercial membership contracts with employer groups, subject to cancellation by the employer group on 30-day written notice. Our Medicare contracts with CMS renew annually. Our military services contracts with the federal government and certain contracts with various state Medicaid programs generally are multi-year contracts subject to annual renewal provisions.

We receive monthly premiums from the federal government and various states according to government specified payment rates and various contractual terms. We bill and collect premiums from employer groups and members in our Medicare and other individual products monthly. Changes in premium revenues resulting from the periodic changes in risk-adjustment scores derived from medical diagnoses for our membership are estimated by projecting the ultimate annual premium and recognized ratably during the year with adjustments each period to reflect changes in the ultimate premium.

Premiums revenue is estimated by multiplying the membership covered under the various contracts by the contractual rates. Premiums revenue is recognized as income in the period members are entitled to receive services, and is net of estimated uncollectible amounts, retroactive membership adjustments, and adjustments to recognize rebates under the minimum benefit ratios required under the Health Care Reform Law. We estimate policyholder rebates by projecting calendar year minimum benefit ratios for the small group and large group markets, as defined by the Health Care Reform Law using a methodology prescribed by HHS, separately by state and legal entity. Medicare Advantage products are also subject to minimum benefit ratio requirements under the Health Care Reform Law. Estimated calendar year rebates recognized ratably during the year are revised each period to reflect current experience. Retroactive membership adjustments result from enrollment changes not yet processed, or not yet reported by an employer group or the government. We routinely monitor the collectability of specific accounts, the aging of receivables, historical retroactivity trends, estimated rebates, as well as prevailing and anticipated economic conditions, and reflect any required adjustments in current operations. Premiums received prior to the service period are recorded as unearned revenues.

Medicare Risk-Adjustment Provisions

CMS uses a risk-adjustment model which adjusts premiums paid to Medicare Advantage, or MA, plans according to health status of covered members. The risk-adjustment model, which CMS implemented pursuant to the Balanced Budget Act of 1997 (BBA) and the Benefits Improvement and Protection Act of 2000 (BIPA), generally pays more where a plan's membership has higher expected costs. Under this model, rates paid to MA plans are based on actuarially determined bids, which include a process whereby our prospective payments are based on our estimated cost of providing standard Medicare-covered benefits to an enrollee with a "national average risk profile." That baseline payment amount is adjusted to account for certain demographic characteristics and health status of our enrolled members. Under the risk-adjustment methodology, all MA plans must collect from providers and submit the necessary diagnosis code information to CMS within prescribed deadlines. The CMS risk-adjustment model uses the diagnosis data, collected from providers, to calculate the health status-related risk-adjusted premium payment to MA plans, which CMS further adjusts for coding pattern differences between the health plans and the government fee-for-service (FFS) program. We generally rely on providers, including certain providers in our network who are our employees, to code their claim submissions with appropriate diagnoses, which we send to CMS as the basis for our health status-adjusted payment received from CMS under the actuarial risk-adjustment model. We also rely on these providers to document appropriately all medical data, including the diagnosis data submitted with claims. In addition, we conduct medical record reviews as part of our data and payment accuracy compliance efforts, to more accurately reflect diagnosis conditions under the risk adjustment model. For additional information, refer to Note 17 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" and Part I, Item 1A, "Risk Factors" of this Form 10-K.

Investment Securities

Investment securities totaled $18.6 billion, or 40% of total assets at December 31, 2024, and $17.0 billion, or 36% of total assets at December 31, 2023. The investment portfolio was primarily comprised of debt securities, detailed below, at December 31, 2024 and December 31, 2023. The fair value of investment securities were as follows at December 31, 2024 and 2023:

(dollars in millions)

Approximately 97% of our debt securities were investment-grade quality, with a weighted average credit rating of AA- by S&P at December 31, 2024. Most of the debt securities that were below investment-grade were rated B+, the higher end of the below investment-grade rating scale. Tax-exempt municipal securities were diversified among general obligation bonds of states and local municipalities in the United States as well as special revenue bonds issued by municipalities to finance specific public works projects such as utilities, water and sewer, transportation, or education. Our general obligation bonds are diversified across the United States with no individual state exceeding approximately 1% of our total debt securities. Our investment policy limits investments in a single issuer and requires diversification among various asset types.

Gross unrealized losses and fair values aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position were as follows at December 31, 2024:

(in millions)

Under the current expected credit losses model, or CECL, expected losses on available for sale debt securities are recognized through an allowance for credit losses rather than as reductions in the amortized cost of the securities. For debt securities whose fair value is less than their amortized cost which we do not intend to sell or are not required to sell, we evaluate the expected cash flows to be received as compared to amortized cost and determine if an expected credit loss has occurred. In the event of an expected credit loss, only the amount of the impairment associated with the expected credit loss is recognized in income with the remainder, if any, of the loss recognized in other comprehensive income. To the extent we have the intent to sell the debt security or it is more likely than not we will be required to sell the debt security before recovery of our amortized cost basis, we recognize an impairment loss in income in an amount equal to the full difference between the amortized cost basis and the fair value.

Potential expected credit loss impairment is considered using a variety of factors, including the extent to which the fair value has been less than cost; adverse conditions specifically related to the industry, geographic area or financial condition of the issuer or underlying collateral of a debt security; changes in the quality of the debt security's credit enhancement; payment structure of the debt security; changes in credit rating of the debt security by the rating agencies; failure of the issuer to make scheduled principal or interest payments on the debt security and changes in prepayment speeds. For debt securities, we take into account expectations of relevant market and economic data. For example, with respect to mortgage and asset-backed securities, such data includes underlying loan level data and structural features such as seniority and other forms of credit enhancements. We estimate the amount of the expected credit loss component of a debt security as the difference between the amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate of future cash flows discounted at the implicit interest rate at the date of purchase. The expected credit loss cannot exceed the full difference between the amortized cost basis and the fair value.

We participate in a securities lending program to optimize investment income. We loan certain investment securities for short periods of time in exchange for collateral initially equal to at least 102% of the fair value of the investment securities on loan. The fair value of the loaned investment securities is monitored on a daily basis, with additional collateral obtained or refunded as the fair value of the loaned investment securities fluctuates. The collateral, which may be in the form of cash or U.S. Government securities, is deposited by the borrower with an independent lending agent. Any cash collateral, which is reinvested by the lending agent primarily in short-term, highly liquid investments, is recorded as a securities lending collateral asset within other current assets on our consolidated balance sheet at the end of the reporting period. We record a corresponding liability to reflect our obligation to return the collateral within trade accounts payable and accrued expenses on our consolidated balance sheet at the end of the reporting period. Collateral received in the form of securities is not recorded in our consolidated balance sheets because, absent default by the borrower, we do not have the right to sell, pledge or otherwise reinvest securities collateral. Loaned securities continue to be carried as investment securities on the consolidated balance sheet at the end of the reporting period. Earnings on the invested cash collateral, net of expense, associated with the securities lending payable are recorded as investment income.

The risks inherent in assessing the impairment of an investment include the risk that market factors may differ from our expectations, facts and circumstances factored into our assessment may change with the passage of time, or we may decide to subsequently sell the investment. The determination of whether a decline in the value of an investment is related to a credit event requires us to exercise significant diligence and judgment. The discovery of new information and the passage of time can significantly change these judgments. The status of the general economic environment and significant changes in the national securities markets influence the determination of fair value and the assessment of investment impairment. There is a continuing risk that declines in fair value may occur and additional material realized losses from sales or expected credit loss impairments may be recorded in future periods.

All issuers of debt securities we own that were trading at an unrealized loss at December 31, 2024 remain current on all contractual payments. After taking into account these and other factors previously described, we believe these unrealized losses primarily were caused by an increase in market interest rates in the current markets since the time the debt securities were purchased. At December 31, 2024, we did not intend to sell any debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not likely that we will be required to sell these debt securities before recovery of their amortized cost basis. Additionally, we did not record any material credit allowances for debt securities that were in an unrealized loss position at December 31, 2024, 2023 or 2022.

Goodwill, Indefinite-lived and Long-lived Assets

At December 31, 2024, goodwill, indefinite-lived and other long-lived assets represented 29% of total assets and 83% of total stockholders’ equity, compared to 30% and 87%, respectively, at December 31, 2023. The decrease in goodwill, indefinite-lived and other long-lived assets as a percentage of total assets is primarily attributable to the increase in investment securities.

For goodwill, we are required to test at least annually for impairment at a level of reporting referred to as the reporting unit, and more frequently if adverse events or changes in circumstances indicate that the asset may be impaired. A reporting unit either is our operating segments or one level below the operating segments, referred to as a component, which comprise our reportable segments. A component is considered a reporting unit if the component constitutes a business for which discrete financial information is available that is regularly reviewed by management. We are required to aggregate the components of an operating segment into one reporting unit if they have similar economic characteristics. Goodwill is assigned to the reporting unit that is expected to benefit from a specific acquisition.

We perform a quantitative assessment to review goodwill for impairment to determine both the existence and amount of goodwill impairment, if any. Our strategy, long-range business plan, and annual planning process support our goodwill impairment tests. These tests are performed, at a minimum, annually in the fourth quarter, and are based on an evaluation of future discounted cash flows. We rely on this discounted cash flow analysis to determine fair value. However, outcomes from the discounted cash flow analysis are compared to other market approach valuation methodologies for reasonableness. We use discount rates that correspond to a market-based weighted-average cost of capital and terminal growth rates that correspond to long-term growth prospects, consistent with the long-term inflation rate. Key assumptions in our cash flow projections, including changes in membership, premium yields, medical and operating cost trends, and certain government contract extensions, are consistent with those utilized in our long-range business plan and annual planning process. If these assumptions differ from actual, including the impact of the Health Care Reform Law or changes in government reimbursement rates, the estimates underlying our goodwill impairment tests could be adversely affected. The fair value of our reporting units with significant goodwill exceeded carrying amounts by a substantial margin. However, unfavorable changes in key assumptions or combinations of assumptions including a significant increase in the discount rate, decrease in the long-term growth rate or substantial reduction in our underlying cash flow assumptions, including revenue growth rates, operating cost trends, and projected operating income could have a significant negative impact on the estimated fair value of our home solutions reporting unit, which accounted for $4.4 billion of goodwill. Impairment tests completed for 2024, 2023, and 2022 did not result in an impairment loss.

Indefinite-lived intangible assets relate to Certificate of Needs (CON) and Medicare licenses acquired in connection with our CenterWell Home Health (formerly Kindred at Home) acquisition with a carrying value of $1.2 billion at December 31, 2024. Like goodwill, we are required to test at least annually for impairment and more frequently if adverse events or changes in circumstances indicate that the asset may be impaired. These tests are performed, at a minimum, annually in the fourth quarter. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized. Fair values of indefinite-lived intangible assets are determined based on the income approach. For our CON intangible assets, unfavorable changes in key assumptions or combinations of assumptions, including a significant increase in the discount rate, decrease in the long-term growth rate or substantial reduction in the underlying cash flow assumptions, including revenue growth rates, operating cost trends, and projected operating income could have a significant negative impact on the estimated fair value of our CON intangible assets, which account for $910 million of our intangible assets. Impairment tests completed for 2024 and 2023 resulted in impairment charges of $200 million and $55 million, respectively. Impairment test completed for 2022 did not result in a material impairment charge. These charges reflect the amount by which the carrying value exceeded its estimated fair value. The fair values of the assets were measured using Level 3 inputs, such as projected revenues and operating cash flows.

Long-lived assets consist of property and equipment and other definite-lived intangible assets. These assets are depreciated or amortized over their estimated useful life, and are subject to impairment reviews. We periodically review long-lived assets whenever adverse events or changes in circumstances indicate the carrying value of the asset may not be recoverable. In assessing recoverability, we must make assumptions regarding estimated future cash flows and other factors to determine if an impairment loss may exist, and, if so, estimate fair value. We also must estimate and make assumptions regarding the useful life we assign to our long-lived assets. If these estimates or their related assumptions change in the future, we may be required to record impairment losses or change the useful life, including accelerating depreciation or amortization for these assets. Other than the impairment charges as described in Footnote 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K, there were no other impairment losses in the last three years.

Our earnings and financial position are exposed to financial market risk, including those resulting from changes in interest rates.

The level of our pretax earnings is subject to market risk due to changes in interest rates and the resulting impact on investment income and interest expense. We have entered into interest-rate swap agreements with major financial institutions to convert our interest-rate exposure on some of our senior notes payable from fixed rates to variable rates, based on Secured Overnight Financing Rate (SOFR), to align interest costs more closely with floating interest rates received on our cash equivalents and investment securities Under the revolving credit agreements, at our option, we can borrow on either a competitive advance basis or a revolving credit basis. The revolving credit portion bears interest at either Term SOFR or the base rate plus a spread. The competitive advance portion of any borrowings will bear interest at market rates prevailing at the time of borrowing on either a fixed rate or a floating rate based on Term SOFR, at our option. There were no borrowings outstanding under our credit agreements at December 31, 2024 or December 31, 2023.

Interest rate risk also represents a market risk factor affecting our consolidated financial position due to our significant investment portfolio, consisting primarily of fixed maturity securities of investment-grade quality with a weighted average S&P credit rating of AA- at December 31, 2024. Our net unrealized loss position increased $89 million from a net unrealized loss position of $1.3 billion at December 31, 2023 to a net unrealized loss position of

$1.4 billion at December 31, 2024. At December 31, 2024, we had gross unrealized losses of $1.4 billion on our investment portfolio primarily due to an increase in market interest rates since the time the securities were purchased. We did not record any material credit allowances for debt securities that were in an unrealized loss position during 2024 and 2023. While we believe that these impairments will be recovered and we currently do not have the intent to sell such securities, given the current market conditions and the significant judgments involved, there is a continuing risk that future declines in fair value may occur and material realized losses from sales or credit loss impairments may be recorded in future periods.

Duration is the time-weighted average of the present value of the bond portfolio’s cash flow. Duration is indicative of the relationship between changes in fair value and changes in interest rates, providing a general indication of the sensitivity of the fair values of our fixed maturity securities to changes in interest rates. However, actual fair values may differ significantly from estimates based on duration. The average duration of our investment portfolio, including cash and cash equivalents, was approximately 3.8 years as of December 31, 2024 and 3.0 years as of December 31, 2023. Based on the duration including cash equivalents, a 1% increase in interest rates would generally decrease the December 31, 2024 fair value of our securities by approximately $783 million.

We have also evaluated the impact on our investment income and interest expense resulting from a hypothetical change in interest rates of 100, 200, and 300 basis points over the next twelve-month period, as reflected in the following table. The evaluation was based on our investment portfolio, outstanding indebtedness, and outstanding swap contract portfolio at December 31, 2024 and 2023. Our investment portfolio consists of cash, cash equivalents, and investment securities. The modeling technique used to calculate the pro forma net change in pretax earnings considered the cash flows related to fixed income investments and debt, which are subject to interest rate changes during a prospective twelve-month period. This evaluation measures parallel shifts in interest rates and may not account for certain unpredictable events that may affect interest income, including unexpected changes of cash flows into and out of the portfolio, changes in the asset allocation, including shifts between taxable and tax-exempt securities, spread changes specific to various investment categories and the mix of short-term versus long-term debt. In the past ten years, changes in 10 year US treasury rates during the year have not exceeded 300 basis points, have changed between 200 and 300 basis points one time, have changed between 100 and 200 basis points five times, and have changed by less than 100 basis points four times.

(a) As of December 31, 2024 and 2023, none of our investments had interest rates below 1%.

(b) The interest rate under our senior notes, which represent 100% and 93% at December 31, 2024 and 2023, respectively, of total debt, is fixed, unaffected by changes in interest rates. We did not have any variable rate term loans at December 31, 2024 and December 31, 2023. There were no borrowings outstanding under the credit agreement at December 31, 2024 or December 31, 2023. There was $871 million outstanding under our commercial paper program at December 31, 2023 with none outstanding at December 31, 2024. At December 31, 2023, our interest rates under our commercial paper program was not less than 1%.

Management’s Responsibility for Financial Statements and Other Information

We are responsible for the preparation and integrity of the consolidated financial statements appearing in our Annual Report. The consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States and include amounts based on our estimates and judgments. All other financial information in this report has been presented on a basis consistent with the information included in the financial statements.

Our control environment is the foundation for our system of internal control over financial reporting and is embodied in our Code of Ethics and Business Conduct, which we currently refer to as the Humana Inc. Ethics Every Day. It sets the tone of our organization and includes factors such as integrity and ethical values. Our internal control over financial reporting is supported by formal policies and procedures which are reviewed, modified and improved as changes occur in business conditions and operations.

The Audit Committee of the Board of Directors, which is composed solely of independent outside directors, meets periodically with members of management, the internal auditors and our independent registered public accounting firm to review and discuss internal controls over financial reporting and accounting and financial reporting matters. Our independent registered public accounting firm and internal auditors report to the Audit Committee and accordingly have full and free access to the Audit Committee at any time.

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to members of senior management and the Board of Directors.

Based on our evaluation as of December 31, 2024, we as the principal executive officer, the principal financial officer and the principal accounting officer of the Company have concluded that the Company’s disclosure controls and procedures (as defined in the Securities Exchange Act of 1934) are effective to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported as specified in Securities and Exchange Commission rules and forms.

Management’s Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining effective internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate or that the degree of compliance with the policies or procedures may deteriorate.

We assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2024. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013). Based on our assessment, we determined that, as of December 31, 2024, the Company’s internal control over financial reporting was effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers LLP, our independent registered public accounting firm, who also audited the Company’s consolidated financial statements included in our Annual Report on Form 10-K, as stated in their report which appears on pages 114-116.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
