## Management's discussion and analysis

As filed, 68,668 characters.

Southwest Gas Holdings, Inc. is a holding company that owns all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas distribution” segment), and through April 22, 2024, owned all of the shares of common stock of Centuri Group, Inc. (the “utility infrastructure services” segment). Southwest Gas Holdings, Inc. and its subsidiaries are collectively referred to as the “Company.” References to “Centuri” relate to Centuri Group, Inc., for periods prior to April 22, 2024, or more recently, to Centuri Holdings, Inc.

In December 2022, the Company announced that its Board of Directors (the “Board”) unanimously determined to take strategic actions to simplify the Company’s portfolio of businesses. These actions included entering into a definitive agreement to sell 100% of MountainWest in an all-cash transaction that closed on February 14, 2023. Additionally, the Company determined it would pursue a separation of Centuri, including forming a new independent publicly traded utility infrastructure services company.

In April 2024, the Company and Centuri Holdings, Inc. announced the completion of an initial public offering (“IPO”) of Centuri’s common stock, with the issuance of 14,260,000 shares ($0.01 par value) at a price of $21.00 per share, along with a concurrent private placement of 2,591,929 shares, at a price equal to the IPO price, with Icahn Partners LP and Icahn Partners Master Fund LP, investment entities associated with Carl C. Icahn. The Company owns approximately 81% of Centuri following these events. Through the first quarter of 2024 and leading up to the IPO, Centuri was a wholly owned subsidiary of Southwest Gas Holdings, Inc. The net proceeds to Centuri from the IPO and the concurrent private placement totaled approximately $328 million, including optional purchase of IPO shares from underwriters. The Company intends to further reduce its ownership interest in future periods by means of: sales of its remaining Centuri shares into the market, a distribution of Centuri shares to Company stockholders, an exchange of Centuri shares for Southwest Gas Holdings, Inc. shares, or a combination thereof.

Our business includes Southwest, which is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Southwest is the largest regulated distributor of natural gas in Arizona and Nevada, and also distributes and transports natural gas for customers in portions of California. Additionally, through its subsidiaries, Southwest operates two regulated interstate pipelines serving portions of Nevada and California. Southwest makes investments in infrastructure to support customer demand associated with population growth and economic development activity and the safe and reliable operation of its system through adherence to integrity management programs.

As of June 30, 2024, Southwest had 2,241,000 residential, commercial, industrial, and other natural gas customers, of which 1,201,000 customers were located in Arizona, 834,000 in Nevada, and 206,000 in California. Over the past twelve months, first-time meter sets were approximately 40,000, compared to 42,000 for the twelve months ended June 2023. Residential and small commercial customers represented over 99% of the total customer base. During the twelve months ended June 30, 2024, 54% of operating margin (Regulated operations revenues less the net cost of gas sold) was earned in Arizona, 34% in Nevada, and 12% in California. During this same period, Southwest earned 86% of its operating margin from residential and small commercial customers, 4% from other sales customers, and 10% from transportation customers. These patterns are expected to remain materially consistent for the foreseeable future.

Southwest recognizes operating revenues from the distribution and transportation of natural gas (and related services) to customers. Operating margin is a financial measure defined by management as Regulated operations revenues less the net cost of gas sold. However, operating margin is not specifically defined in accounting principles generally accepted in the United States (“U.S. GAAP”). Thus, operating margin is considered a non-GAAP measure. Management uses this financial measure because Regulated operations revenues include the net cost of gas sold, which is a tracked cost that is passed through to customers without markup under purchased gas adjustment (“PGA”) mechanisms. Fluctuations in the net cost of gas sold impact revenues on a dollar-for-dollar basis, but do not impact operating margin or operating income. Therefore, management believes operating margin provides investors and other interested parties with useful and relevant information to analyze Southwest’s financial performance in a rate-regulated environment. The principal factors affecting changes in operating margin are general rate relief (including impacts of infrastructure trackers) and customer growth. Commission decisions on the amount and timing of relief may impact our earnings. Refer to the Summary Operating Results table below for a reconciliation of gross margin to operating margin, and refer to *Rates and Regulatory Proceedings* in this Management’s Discussion and Analysis, for details of various rate proceedings.

The demand for natural gas is seasonal, with greater demand in the colder winter months and decreased demand in the warmer summer months. All of Southwest’s service territories have decoupled rate structures (alternative revenue programs), which are designed to eliminate the direct link between volumetric sales and revenue, thereby mitigating the impacts of weather variability and conservation on operating margin, allowing Southwest to pursue energy efficiency initiatives. Nearly all of our customers, and resulting revenue and margin, are included as part of mechanisms that reduce the impact of weather and volume variability on our earnings.

Centuri is a strategic infrastructure services company that partners with regulated utilities to build and maintain the energy network that fuels millions of homes and businesses across the United States (“U.S.”) and Canada. With a commitment to serve as long-term partners to customers and communities, Centuri’s employees enable regulated utilities to safely and reliably deliver natural gas and electricity, as well as achieve their goals for environmental sustainability. Centuri operates in 87 primary locations across 45 states and provinces in the U.S. and Canada. It operates in the U.S., primarily as NPL, Neuco, Linetec, and Riggs Distler, and in Canada, primarily as NPL Canada.

Utility infrastructure services activity can be impacted by changes in infrastructure replacement programs of utilities, weather, and local and federal regulation (including tax rates and incentives). Utilities continue to implement or modify system integrity management programs to enhance safety pursuant to federal and state mandates. These programs have resulted in multi-year utility system replacement projects throughout the U.S. Likewise, there has been similar attention placed on electric grid modernization through national infrastructure legislation and related initiatives. Generally, Centuri revenues are lowest during the first quarter of the year due to less favorable winter weather conditions. Revenues typically improve as more favorable weather conditions occur during the summer and fall months. In cases of severe weather, such as following a regional storm, Centuri may be engaged to perform restoration activities related to above-ground utility infrastructure, and related results impacts are not solely within the control of management. In addition, in certain circumstances, such as with large bid contracts (especially those of a longer duration), or unit-price contracts with revenue caps, results may be impacted by differences between costs incurred and those anticipated when the work was originally bid. Work awarded, or failing to be awarded, by individual large customers can impact operating results.

All of our businesses may be impacted by economic conditions that impact businesses generally, such as inflationary impacts on goods and services consumed in the business, rising or sustained high interest rates, labor markets and costs (including in regard to contracted or professional services), and the availability of those resources. Certain of these impacts may be more predominant in certain of our operations, such as with regard to fuel costs for work equipment and skilled/trade labor costs at Centuri.

Results from natural gas distribution operations improved $8.5 million between the second quarters of 2024 and 2023. The improvement was primarily due to an increase in Operating margin and decrease in Depreciation and amortization, offset by an increase in Operations and maintenance expense and decrease in Other income.

Operating margin increased $10.8 million quarter over quarter. Combined rate relief in Nevada and California added approximately $18 million of incremental margin, and an additional $2 million is attributable to customer growth, including 40,000 first-time meter sets during the last twelve months. The combined impacts of certain customer rate components related to infrastructure and similar tracking mechanisms (not also impacting amortization expense), and the variable interest expense (“VIE”) adjustment mechanism in Nevada (for which amortization is recognized in interest expense), resulted in a combined $2 million of incremental margin between comparable periods. Furthermore, late fee assessments on customer account balances provided $1.2 million in incremental margin. Offsetting these impacts was a decrease in recoveries associated with other regulatory program balances of $16.1 million, for which an associated comparable decrease is also reflected in amortization expense (discussed below). The remaining variance primarily relates to changes in other miscellaneous revenue and revenue from customers outside of the decoupling mechanisms.

Operations and maintenance expense increased $4.9 million or 4% between quarters. General cost increases were experienced in a variety of areas, including in employee labor-related and benefit costs, leak survey and line locating activities, as well as insurance costs. These increases were partially offset by a reduction in external contractor and professional services expenses.

Depreciation and amortization expense decreased $13.2 million, or 18%, between quarters, driven primarily by $16.1 million in lower amortization associated with regulatory program balances (noted above), including changes in the amount of, and a shift in the timing of, the California Climate Credit return (from being returned and therefore, amortized, during the first quarter of 2023 to reverting to the more typical timing in the second quarter of 2024). This decrease was partially offset by an increase in depreciation on gas plant, reflective of a $695 million, or 7%, increase in average gas plant in service since the corresponding second quarter of 2023. The increase in plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure.

Other income (which is net of other deductions) decreased $4.5 million. Interest income declined $5.4 million between quarters primarily reflecting a reduction in carrying charges associated with regulatory account balances, notably, deferred purchased gas cost balances, which, on a combined basis, decreased from an asset balance of $786 million as of June 30, 2023 to a net liability balance of $82 million as of June 30, 2024. Interest is earned when balances are assets and interest expense is incurred when balances are liabilities. A $2.9 million decrease in values (including net death benefits) associated with company-owned life insurance (“COLI”) policies and a $1.1 million increase in non-service-related costs associated with employee pension and other postretirement benefits also contributed to the decrease overall between periods. Offsetting these decreases was a $1.8 million increase in the equity portion of the allowance for funds used during construction, and approximately $3 million in software write-offs in the prior year period, which did not recur in 2024.

Net interest deductions increased approximately $2.7 million in the second quarter of 2024, as compared to the prior-year quarter, primarily due to the regulatory treatment associated with Southwest’s Industrial development revenue bonds (the VIE mechanism noted above), including the impacts of deferrals and return/recoveries included in revenue/operating margin that are amortized through interest expense.

| Contribution to consolidated results | $163,419 | $153,816 |

Results from natural gas distribution operations improved approximately $10 million between the first six months of 2024 and 2023. The improvement was primarily due to an increase in Operating margin and decrease in Depreciation and amortization, offset by an increase in Operations and maintenance expense.

Operating margin increased $20 million period over period. Approximately $7 million of incremental margin was attributable to customer growth, including 40,000 first-time meter sets during the last twelve months. Combined rate relief across all our service territories added approximately $28 million of incremental margin. Favorable impacts ($4.5 million, combined) were also realized in connection with certain rate components of infrastructure trackers and the Nevada VIE mechanism. Offsetting these increases was a decrease in recoveries associated with other regulatory programs, totaling $9.6 million, for which an associated comparable decrease is also reflected in amortization expense (discussed below). Furthermore, an $8 million out-of-period favorable gas cost adjustment in the prior-year period did not recur in 2024. Customary gas used in operations (the effects of which are offset in Operations and maintenance expense) also reduced operating margin ($3.8 million) in the current period. Changes in miscellaneous revenue and customers outside of the decoupling mechanisms comprise the remaining variance.

Operations and maintenance expense increased $4.6 million, or 2%, between periods. General cost increases were experienced in a variety of areas, including in employee labor-related and benefit costs ($2.4 million), leak survey and line locating activities ($3.7 million), and insurance costs. These increases were partially offset by impacts from the cost of fuel used in operations ($3.8 million, as noted above) and a reduction in other contractor and professional services ($3.3 million).

Depreciation and amortization expense decreased approximately $3 million, or 2%, between periods, due primarily to a decrease of $9.6 million in amortization associated with the recovery of regulatory program balances, including a sizeable difference in the amount of the California Climate Credit between periods. This decrease was offset by an increase in depreciation on gas plant, reflective of a $686 million, or 7%, increase in average gas plant in service since the corresponding period of 2023. The increase in plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure.

Other income (which is net of other deductions) decreased approximately $4.9 million. Interest income declined $8.1 million between periods primarily reflecting a reduction to carrying charges associated with regulatory account balances, notably, deferred purchased gas cost balances, which decreased from an asset balance of $786 million as of June 30, 2023 to a net liability balance of $82 million as of June 30, 2024. Offsetting these decreases was a $3.7 million increase in the equity portion of the allowance for funds used during construction. Non-service components of postretirement benefit costs increased in 2024, but COLI policy death benefits and nonrecoverable software write-offs experienced in the prior year period did not recur in 2024.

Net interest deductions increased $0.6 million in the first six months of 2024, as compared to the prior-year period, including offsetting impacts of $300 million of Senior Notes issued in March 2023 and the payoff in April 2023 of a $450 million term loan.

Utility infrastructure services revenues decreased $133.7 million, or 17%, in the second quarter of 2024 when compared to the prior-year quarter, driven by decreases in electric utility infrastructure services (“Electric”) revenues of $67.1 million, and $58.3 million gas utility infrastructure services (“Gas”) revenues. The decrease in Electric revenues was primarily due to a reduction in net volume of work under existing master services agreements (“MSAs”), and a decrease specific to offshore wind revenues of $20.8 million due to timing of project completion. Included in current period Electric revenue was $36.4 million from emergency restoration services following storm damage to U.S. customers’ above-ground utility infrastructure, compared to $33.9 million in emergency restoration services in the same quarter in the prior year. The decrease in Gas revenues was primarily due to a reduction in net volume of work under existing customer MSAs and timing of bid projects, as the prior year benefited from the commencement of a large project that has since been completed.

Utility infrastructure services expenses decreased $111.2 million, or 16%, in the second quarter of 2024 when compared to the prior-year quarter due primarily to a lower volume of infrastructure services provided. Subcontractor costs decreased during the second quarter of 2024 compared to the prior-year quarter primarily due to decreased work under offshore wind projects and change in the mix of work. Margin on jobs in the second quarter of 2024 also decreased primarily due to lower margins on bid work, one-time severance incurred in the current period, decreased volumes leading to underutilization of fixed costs, and unfavorable changes in the mix of work. Included in total Utility infrastructure services expenses were general and administrative costs, which decreased approximately $9.4 million between quarters primarily due to lower incentive compensation during the current period and reductions in corporate salary and benefit costs. Gains on sale of equipment in the second quarter of 2024 and 2023 (reflected as an offset to Utility infrastructure services expenses) were approximately $1.1 million and $1.2 million, respectively.

Depreciation and amortization expense decreased $2.5 million between quarters, primarily due to a number of small tools within Electric operations becoming fully depreciated in 2023 and not requiring replacement based on project needs. Additionally, more efficient utilization of existing fixed assets in recent periods has slowed the growth of the depreciable asset base, highlighted by capital expenditures of $106.6 million in 2023 compared to capital expenditures of $130.2 million in 2022, which impacted depreciation on a relative basis in the periods following.

The decrease in net interest deductions of $1.9 million between quarters was primarily due to a reduction in the average debt balance as Centuri paid down $156 million of debt under its revolving credit facility and $160 million of debt under its term loan facility with proceeds from its April IPO and concurrent private placement.

Utility infrastructure services revenues decreased $259 million, or 18%, in the first six months of 2024 when compared to the prior-year comparative period, driven primarily by decreases in Electric revenues of $148.9 million, and Gas revenues of $95.7 million. The decline in Electric revenues was primarily due to a net reduction in volume of work under MSAs, as well as a decrease in offshore wind revenues of $33.4 million due to timing of project completion, and due to a decrease in emergency restoration services of $18.9 million during the period ($45.6 million in the current period, compared to $64.5 million in the previous period). The decrease in Gas revenues was primarily due to a reduction in net volumes under existing customer MSAs and timing of bid projects, as the prior year benefited from the commencement of a large project that has since been completed.

Utility infrastructure services expenses decreased $199.2 million, or 15%, between periods. The overall decrease was primarily due to lower volume of infrastructure services provided. Subcontractor costs decreased during the period of 2024 compared to the prior-year period primarily due to decreased work under offshore wind projects and changes in mix of work. Margin on jobs also decreased in the current year-to-date period compared to the same period in the prior year due to unfavorable winter weather, lower margins on bid work, a reduction in more profitable emergency restoration services between periods, and underutilization of fixed costs due to the lower volume of work. General and administrative costs included in total utility infrastructure services expenses decreased approximately $4.4 million between comparative periods primarily due to lower incentive compensation and lower corporate salary and benefit costs during the current period, partially offset by an increase in one-time severance and strategic review costs. Gains on sale of equipment in the first six months of 2024 and 2023 (reflected as an offset to Utility infrastructure services expenses) were approximately $2 million and $1.8 million, respectively.

Depreciation and amortization expense decreased $6 million between periods, primarily due to a number of small tools within Electric operations becoming fully depreciated in 2023 and not requiring replacement based on project needs. Additionally, more efficient utilization of existing fixed assets in recent periods has slowed the growth of the depreciable asset base, as discussed above.

Income tax benefit increased $13.5 million between quarters, primarily due to differences in pre-tax income and provisions under the tax law.

Rates and Regulatory Proceedings

Southwest is subject to the regulation of the Arizona Corporation Commission (“ACC”), the Public Utilities Commission of Nevada (the “PUCN”), the California Public Utilities Commission (the “CPUC”), and two of Southwest’s subsidiaries are subject to regulation by the Federal Energy Regulatory Commission (the “FERC”).

#### Arizona Jurisdiction

*Arizona General Rate Case.* Southwest filed its 2024 Arizona rate case application in early February 2024, proposing an increase in revenue of approximately $126 million to reflect the continued significant capital investments in the state and to update rates to more closely align with Southwest’s current level of operations and maintenance expense. The request includes a return on common equity of 10.15% and a 0.81% fair value increment, relative to a 50% target equity ratio and a proposed twelve-month post-test year adjustment for non-revenue producing plant. In addition to proposing the continuation of full revenue decoupling under the Delivery Charge Adjustment (“DCA”) mechanism, Southwest proposed the establishment of the System Improvement Benefit (“SIB”) mechanism, a capital tracker designed to support required code and regulatory-related infrastructure replacements. Southwest also proposed to set the carrying cost for the interest component of the DCA and Gas Cost Balancing Account (“GCBA”) rate adjustment mechanisms to equal the Commission-authorized Weighted Average Cost of Capital, and to establish an Unrecovered Gas Cost Expense Provision (“UGCE”), which represents the gas cost-related portion of net write-offs of uncollectible customer accounts. The UGCE would allow Southwest to more timely recover commodity and related components of such accounts. Rates, following the conclusion of the rate case, are anticipated to become effective in the second quarter of 2025. Southwest’s existing general rates became effective February 1, 2023 following the conclusion of the previous general rate case.

*Delivery Charge Adjustment.* The DCA, or Arizona decoupling mechanism, as described above, includes a filing each April, which along with other reporting requirements, contemplates a rate to return/recover the over- or under-collected margin balance. The existing rate to return the over-collected balance existing as of March 31, 2023 was approved and became effective August 1, 2023. The most recent filing was made in April 2024, requesting to update rates to address the $17.5 million over-collected balance existing as of March 31, 2024, and is anticipated to be implemented in the third quarter of 2024.

*Tax Reform.* A Tax Expense Adjustor Mechanism (“TEAM”) was approved in Southwest’s 2019 general rate case to timely recognize tax rate changes resulting from federal or state tax legislation following the TEAM implementation. In addition, the TEAM tracks and returns/recovers the revenue requirement impact of changes in the amortization of excess accumulated deferred income taxes (“EADIT”), including that which resulted from 2017 U.S. federal tax reform, compared to the amount authorized in the most recently concluded rate case. Following the inaugural surcredit rate establishment under the TEAM mechanism in December 2022, Southwest has filed subsequent TEAM rate applications, including a recent filing, which proposed to update the TEAM surcredit to refund $5.03 million of estimated EADIT savings. The adjusted rate became effective June 1, 2024.

*Customer-Owned Yard Line (“COYL”) Program*. Southwest originally received approval, in connection with its 2010 Arizona general rate case, to implement a program to conduct leak surveys, and if leaks were present, to replace and relocate service lines and meters for Arizona customers whose meters were placed away from the customer’s home, representing a non-traditional configuration. The COYL program has been subject to proceedings to recover investments since that time. In February 2024, Southwest requested approval to recover the outstanding revenue requirement of approximately $1.8 million associated with 2023 COYL investments. The adjusted rate became effective June 15, 2024.

*PGA Modification*. On March 1, 2023, Southwest filed a request to adjust the interest rate applicable to the outstanding Purchased Gas Adjustment (“PGA”) balance to more closely match the interest expense incurred to finance the balance. In the alternative, the filing requested an expansion of the current GCBA adjustment to clear the then existing $351 million balance. In July 2023, the ACC approved an increase to the GCBA rate (over a two-year period) effective August 1, 2023, to support the timely recovery of the approximately $358 million balance as of May 31, 2023. The increased GCBA rate will remain for up to two years or until the balance drops below $10 million, at which point the GCBA rate will be set to $0.00 per therm, where it will remain until the under- or over-collected balance exceeds $10 million. The ongoing deferred energy rates, separate from the GCBA rates, continue to be updated monthly.

#### Nevada Jurisdiction

*Nevada General Rate Case*. Southwest filed its most recent general rate case in September 2023 based on the test year ended May 2023. The initial request was updated with a certification filing primarily for plant placed in service and incremental annual leak survey costs through November 2023. Those updates resulted in an updated overall request of $74 million, an increase over the initial request of $69.8 million. A stipulation was reached with Regulatory Operations Staff and the Bureau of Consumer Protection, settling certain issues and agreeing to a black box settlement with a statewide increase of $65.6 million, before any adjustments for the cost of capital. Following a hearing on cost of capital issues, the PUCN issued a decision approving an annual increase in revenues of $59 million, approving the proposed settlement, and authorizing a return on common equity of 9.5%, including the use of a hypothetical capital structure of 50% debt and 50% equity. Included in the settled items were a continuation of full revenue decoupling; authority to continue tracking incremental annual leak survey costs in a regulatory asset (discussed further below); and refreshed depreciation rates that are somewhat lower than proposed. New rates became effective in April 2024.

*General Revenues Adjustment.* The General Revenues Adjustment (“GRA”), or Nevada decoupling mechanism, was affirmed as part of Southwest’s most recently concluded general rate case and adjustments are included in the Annual Rate Adjustment (“ARA”) filings intended to update rates to recover/return amounts associated with various regulatory mechanisms, including the GRA. Southwest made its most recent ARA filing in November 2023 related to the approximate $8.7 million over-collected balance as of September 30, 2023. Recovery of rates and adjustments thereto as part of the ARA primarily impact cash flows, but not net income overall. Updated rates for the GRA and other regulatory mechanisms included in the ARA filing became effective May 1, 2024, earlier than the typical July 1, 2024 effective date.

*Nevada Leak Survey.* In 2019, the PUCN opened an Investigation and Rulemaking action to consider certain amendments to the Nevada Administrative Code requiring annual leak surveys of distribution pipelines transporting natural gas or liquid petroleum. The increased survey activity was to focus on business districts and to be conducted generally on an annual basis (not exceeding 15-month survey intervals). The proposed regulations were permanently adopted effective January 1, 2023. Regulatory asset treatment was approved for the purpose of tracking incremental costs associated with implementing the increased leak surveys. Continuation of the program, along with recovery of earlier incurred amounts over a two-year period, was approved in conjunction with Southwest’s recently completed general rate case.

#### California Jurisdiction

*Attrition Filing.* Following the 2021 implementation of rates approved as part of the most recent general rate case, the continuation of annual Post Test Year (“PTY”) margin attrition increases of 2.75% began in January 2022. The most recent increase included the attrition component, along with adjustments related to the amortization of EADIT, the impact of the Automatic Trigger Mechanism (“ATM”) on authorized rate base, and margin associated with the North Lake Tahoe Lateral replacement project. The ATM adjusts the rate of return up or down (in this case, up) as a result of changes in the average utility bond yield that exceed 100 basis points. The cumulative impact resulted in an annual increase of $11.6 million effective January 2024 for Southwest’s combined southern California, northern California, and South Lake Tahoe rate jurisdictions. The PTY increase of $4.7 million associated with the North Lake Tahoe Lateral revenue requirement became effective February 1, 2024.

*Service Area Extension.* Southwest filed a request to expand its southern California certificated service area, a Certificate of Public Convenience and Necessity (“CPCN”), to include the Army’s National Training Center at Fort Irwin, located northeast of Barstow, California. The CPCN was approved by the CPUC in April 2024 and authorizes Southwest to construct approximately 21 miles of distribution main pipeline to deliver natural gas service to the newly certificated area in Fort Irwin, which at the time of filing was estimated to cost approximately $38.7 million.

#### FERC Jurisdiction

*General Rate Case.* Great Basin Gas Transmission Company (“Great Basin”), a wholly owned subsidiary of Southwest, filed notice of a change in rates (pursuant to applicable regulations) on March 6, 2024, requesting that rates for natural gas service subject to the filing be made effective April 6, 2024. The FERC, however, suspended the case for a five-month period, which will allow rates to go into effect, subject to refund, September 6, 2024. The filing includes a request to continue a term-differentiated rate structure which was adopted as part of Great Basin’s last general rate case, an overall revenue increase of approximately $16 million, and a return on equity of 14.05% and 13.05% applicable to each category of shippers, as applicable, and a capital structure of 44% long-term debt and 56% common equity. A primary driver of the proposed increase is approximately $99 million of capital investments anticipated to be placed in service by the end of the August 31, 2024 test year. Motion rates, subject to refund, are anticipated to become effective in September 2024, with an initial decision during the second quarter of 2025.

PGA Filings

The rate schedules in all of Southwest’s service territories contain provisions that permit adjustment to rates as the cost of purchased gas changes. These deferred energy provisions and purchased gas adjustment clauses are collectively referred to as “PGA” clauses. Differences between gas costs recovered from customers and amounts paid for gas by Southwest result in over- or under-collections. Balances are recovered from or refunded to customers on an ongoing basis with interest. As of June 30, 2024, under-collections in Arizona and California resulted in an asset of approximately $39.8 million and over-collections in southern and northern Nevada resulted in a liability of approximately $121.3 million on the Company’s and Southwest’s Condensed Consolidated Balance Sheets. The substantial reduction in balances between periods in the table below reflects a combination of specific recovery rates in place to collect the build-up of earlier balances as a result of the cost paid for gas in those earlier periods, and recent conditions whereby base rates under the mechanisms have exceeded the cost of recent gas purchases with suppliers, given substantially lower natural gas prices compared to those experienced heading into 2023.

Filings to change rates in accordance with PGA clauses are subject to audit by state regulatory commission staffs. PGA changes impact cash flows but have no direct impact on operating margin. However, gas cost deferrals and recoveries can impact comparisons between periods of individual consolidated income statement components. These include Regulated operations revenues, Net cost of gas sold, Net interest deductions, and Other income (deductions).

The following table presents Southwest’s outstanding PGA balances receivable/(payable):

| (Thousands of dollars) | June 30, 2024 | December 31, 2023 | June 30, 2023 |
| --- | ---: | ---: | ---: |
| Arizona | $31,510 | $251,416 | $338,831 |
| Northern Nevada | (30,392) | 45,757 | 60,781 |
| Southern Nevada | (90,931) | 218,761 | 349,649 |
| California | 8,267 | 36,951 | 36,327 |
|  | $(81,546) | $552,885 | $785,588 |

Capital Resources and Liquidity

Historically, cash on hand and cash flows from operations have provided a substantial portion of cash used in investing activities (primarily for construction expenditures and property additions). In recent years, Southwest has undertaken significant pipe replacement activities to fortify system integrity and reliability, including on an accelerated basis in association with certain gas infrastructure replacement programs. In addition, certain national events, including several major storms in recent years affecting central portions of the U.S., contributed to the periodic run-up in gas supply costs, before commodity costs significantly dropped in more recent periods. This collective activity necessitated the issuance of both debt and equity securities to supplement cash flows from operations, before cash reserves built up at the utility in more recent periods, including from collections under the PGA mechanisms. Southwest Gas Holdings, Inc. and Southwest’s capitalization strategy is to maintain an appropriate balance of equity and debt to preserve investment-grade credit ratings, which help minimize interest costs. Investment-grade credit ratings have been maintained by Southwest Gas Holdings, Inc. and Southwest.

#### Cash Flows

Southwest Gas Holdings, Inc.:

*Operating Cash Flows.* Cash flows provided by consolidated operating activities increased $838 million in the first six months of 2024 as compared to the same period of 2023. The increase was primarily driven by the collection of previously deferred purchased gas costs for Southwest. As noted above, in the previous year rates billed to customers for gas supply costs were lower than actual expenditures. These differences were deferred and are now being collected and have provided a significant source of available funds in the current period. The improvement in cash flows also reflects the impacts of changes in other components of working capital overall, including the timing and amount of accounts payable and other current asset and liability balances.

*Investing Cash Flows.* Cash flows provided by consolidated investing activities decreased $1.03 billion in the first six months of 2024 as compared to the same period of 2023. The overall decrease was driven by $1.05 billion in proceeds received in connection with the MountainWest sale (net of cash sold) in 2023, partially offset by proceeds from the sale of other property.

*Financing Cash Flows.* Cash flows from consolidated financing activities increased $614 million in the first six months of 2024 as compared to the same period of 2023. The overall increase was primarily due to activity in 2023, including the first quarter 2023 repayment ($1.1 billion) of the then remaining balance of the term loan entered into by Southwest Gas Holdings, Inc. in connection with the 2021 acquisition of MountainWest, along with other borrowing and repayment activity in that year. Net financing activities in 2024 include proceeds received ($330 million, excluding $2.4 million of offering expenses that were unpaid as of June 30, 2024) from the Centuri IPO, with the majority of the proceeds used by Centuri to pay down portions of its revolving credit and term loan facility. Financing cash flows also include Centuri’s redemption of the previously remaining redeemable noncontrolling interest in Linetec for $92 million in 2024 (compared to $40 million of partial redemption in the comparable period in the prior year), in addition to utilization of its credit facility for this and other purposes. The prior year period also included proceeds received from the issuance of common stock in an underwritten public offering in March 2023, with no comparable issuance in the current year. Other financing cash flows include borrowings and repayments under the companies’ credit facilities, and an increase in dividends paid between periods.

Corporate and administrative expenses/outflows for Southwest Gas Holdings, Inc. in the first six months of 2024 overall primarily include interest paid on outstanding borrowings and costs associated with the Centuri separation.

The capital requirements and resources of the Company generally are determined independently for the individual business segments. Each business segment is generally responsible for securing its own debt financing sources. However, the holding company may raise funds through stock issuances or other external financing sources in support of each business segment.

Southwest Gas Corporation:

*Operating Cash Flows.* Cash flows provided by operating activities increased approximately $900 million in the first six months of 2024 as compared to the same period of 2023. The improvement in operating cash flows was primarily attributable to the collection of deferred purchased gas costs (as discussed above), as well as cash flows from other working capital changes overall.

*Investing Cash Flows.* Cash used in investing activities decreased $15 million in the first six months of 2024 as compared to the same period of 2023. While outflows for capital expenditures increased by $10 million between periods, the current period also reflects inflows from the sale of property, as well as reduced outflows related to customer advances for construction. See also *Natural Gas Distribution Segment Construction Expenditures, Debt Maturities, and Financing* below.

*Financing Cash Flows.* Net cash from financing activities decreased $561 million in the first six months of 2024 as compared to the same period of 2023. The decline was primarily due to $530 million in parent capital contributions in 2023 with no comparable contribution in the current year. Outflows for dividend payments increased in the current period. Other impacts primarily relate to the mostly offsetting borrowing activity in 2023, including issuance of long- and short-term debt and repayment of short-term debt, along with activity under Southwest’s credit facility in that year. See **Note 5 – Debt.**

#### Natural Gas Distribution Segment Construction Expenditures, Debt Maturities, and Financing

During the six-month period ended June 30, 2024, construction expenditures for the natural gas distribution segment were $391 million. The majority of these expenditures, approximately 55%, were associated with the replacement of existing transmission and distribution pipeline facilities to fortify system integrity and reliability, as well as other general plant expenditures, with the remainder related to new construction.

Management estimates natural gas segment construction expenditures during the three-year period ending December 31, 2026 will be approximately $2.4 billion. Of this amount, approximately $830 million is expected to be incurred during calendar year 2024. Southwest plans to continue to request regulatory support to undertake projects, or to accelerate projects as necessary for the improvement of system flexibility and reliability, or to expand, where relevant, to unserved or underserved areas. Southwest may expand existing, or initiate new, programs. Significant replacement activities are expected to continue well beyond the next few years. See also **Rates and Regulatory Proceedings**. In August 2024, Southwest entered into a new credit facility to replace the existing credit facility that was otherwise set to expire in 2025; the new agreement includes similar terms to the existing facility, but the new agreement extends the maturity date to 2029. Otherwise, Southwest has $75 million of long-term debt maturing in 2026, but no debt maturities in either 2024 or 2025. Also during that same three-year period, cash flows from operating activities of Southwest are expected to provide approximately 78% of the funding for gas operations of Southwest and total construction expenditures and dividend requirements. Any additional cash requirements, including construction-related, and any paydown or refinancing of debt, are expected to be provided by existing credit facilities, parent equity contributions, and/or other external financing sources. The timing, types, and amounts of additional external financings will be dependent on a number of factors, including the cost of gas purchases, conditions in capital markets, timing and amount of rate relief, timing and amount of surcharge collections from, or amounts returned to, customers related to regulatory mechanisms and programs, as well as growth levels in Southwest’s service areas and earnings. External financings may include the issuance of debt securities, bank and other short-term borrowings, and other forms of financing.

#### Dividend Policy

Dividends are payable on the Company’s common stock at the discretion of the Board. In setting the dividend rate, the Board considers, among other factors, current and expected future earnings levels, our ongoing capital expenditure plans, expected external funding needs, our payout ratio, and our ability to maintain investment-grade credit ratings and liquidity. The Company has paid dividends on its common stock since 1956. In February 2024, the Board determined to maintain the quarterly dividend at $0.62 per share, effective with the June 2024 payment. Although no assurances can be provided on our future dividend payments, the Board currently intends to reevaluate the dividend upon the completion of the Centuri separation, and it is anticipated that we will pay a dividend at a level consistent with industry peers.

#### Liquidity

Several factors (some of which are out of the control of the Company) that could significantly affect liquidity in the future include: variability of natural gas prices, changes in ratemaking policies of regulatory commissions, regulatory lag, customer growth in the natural gas distribution segment, the ability to access and obtain capital from external sources, interest rates, changes in income tax laws, pension funding requirements, inflation, and the level of earnings. Natural gas prices and related gas cost recovery rates, as well as plant investment, have historically had the most significant impact on liquidity.

On an interim basis, Southwest defers over- or under-collections of gas costs to PGA balancing accounts. In addition, Southwest uses this mechanism to either refund amounts over-collected or recoup amounts under-collected as compared to the price paid for natural gas during the period since the last PGA rate change went into effect. At June 30, 2024, the balance in the PGA accounts included an under-collection of approximately $39.8 million pertaining to the Arizona and California jurisdictions and an over-collection of $121.3 million pertaining to Nevada. The substantial reduction in the PGA balance as of this date compared to balances existing in recently concluded and comparable earlier periods is also highlighted by the substantial cash balance of $565 million existing as of June 30, 2024. See **PGA Filings** for more information.

Southwest Gas Holdings, Inc. has a credit facility with a borrowing capacity of $300 million that expires in December 2026. This facility is intended for short-term financing needs. At June 30, 2024, $111 million was outstanding under this facility.

In April 2023, Southwest Gas Holdings, Inc. entered into a $550 million Term Loan Credit Agreement (the “Term Loan”) that was set to mature in October 2024. Southwest Gas Holdings, Inc. utilized a majority of the proceeds to make an equity contribution to Southwest. In August 2024, the Company amended its Term Loan agreement, extending the maturity date to July 31, 2025 and changed the interest with reference to SOFR from an applicable margin of 1.300% to 1.125%, among other miscellaneous changes. Management has reflected this indebtedness as long-term borrowings as of June 30, 2024.

Southwest has a credit facility with a borrowing capacity of $400 million, which was set to expire in April 2025, before it was replaced in August 2024, extending the maturity date to 2029, as noted earlier. The operations, designations, and key business terms are comparable to the prior facility. Southwest designates $150 million of capacity under the facility for long-term borrowing needs and the remaining $250 million for working capital purposes. There was no activity on either the long-term or short-term portions of the existing facility during the six-month period ending June 30, 2024. Additionally, at June 30, 2024, no borrowings were outstanding on either the long-term or short-term portions of the existing facility. The credit facility can be used as necessary to meet liquidity requirements, including temporarily financing under-collected PGA balances, or meeting the refund needs of over-collected balances. The credit facility in place has generally been adequate for Southwest’s working capital needs outside of funds raised through operations and other types of external financing. Any additional cash requirements would include utilization of the credit facility, equity contributions from the Company, and/or other external financing sources.

Southwest has a $50 million commercial paper program. Any issuance under the commercial paper program is supported by Southwest’s revolving credit facility and, therefore, does not represent additional borrowing capacity. Any borrowing under the commercial paper program is designated as long-term debt. Interest rates for the commercial paper program are calculated at the current commercial paper rate during the borrowing term. At June 30, 2024, there were no borrowings outstanding under this program.

Centuri has a $1.545 billion secured revolving credit and term loan multi-currency facility. The capacity of the line of credit is $400 million, with related amounts borrowed and repaid being available to be re-borrowed; the term loan facility has a limit of $1.145 billion. The term loan facility expires on August 27, 2028 and the revolving credit facility expires on August 27, 2026. This multi-currency facility allows the borrower to request loan advances in either Canadian or U.S. dollars. The obligations under the credit agreement are secured by present and future ownership interests in substantially all direct and indirect subsidiaries of Centuri, substantially all of the tangible and intangible personal property of each borrower, certain of their direct and indirect subsidiaries, and all products, profits, and proceeds of the foregoing. Centuri assets securing the facility at June 30, 2024 totaled $2.5 billion. The maximum amount outstanding on the combined facility during the first six months of 2024 was $1.117 billion. As of June 30, 2024, $144 million was outstanding on the revolving credit facility, in addition to $831 million that was outstanding on the term loan portion of the facility. Also at June 30, 2024, there was approximately $196 million, net of letters of credit, available for borrowing under the line of credit.

In April 2024, Centuri successfully completed an IPO of 14,260,000 shares of Centuri common stock at a price of $21.00 per share, in addition to a concurrent private placement of 2,591,929 shares at a price equal to the IPO price. The collective net proceeds to Centuri approximated $328 million. Centuri used $316 million of the proceeds to repay amounts outstanding under its revolving credit and term loan facility, with the remainder intended for general corporate purposes. Following the IPO, the Company owns approximately 81% of the outstanding shares of Centuri common stock. The Company intends to further reduce its ownership in Centuri in future periods through: sales of its remaining Centuri shares into the market, a distribution of Centuri shares to Company stockholders, through an exchange of Centuri shares for Southwest Gas Holdings, Inc. shares, or a combination thereof.

#### Critical Accounting Policies and Estimates

As of June 30, 2024, there have been no significant changes with regard to the critical accounting policies and estimates disclosed in the MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2023.

## Market risk

As filed, 238 characters.

See **Item 7A. Quantitative and Qualitative Disclosures about Market Risk** in the 2023 Annual Report on Form 10-K filed with the SEC. No material changes have occurred related to the disclosures about market risk since December 31, 2023.

## Controls and procedures

As filed, 2,099 characters.

Management of Southwest Gas Holdings, Inc. and Southwest Gas Corporation has established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to provide reasonable assurance that information required to be disclosed in their respective reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to management of each company, including each respective Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and benefits of controls must be considered relative to their costs. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or management override of the control. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

Based on the most recent evaluation, as of June 30, 2024, management of Southwest Gas Holdings, Inc. and Southwest Gas Corporation, including the Chief Executive Officer and Chief Financial Officer, believes the Company’s and Southwest’s disclosure controls and procedures are effective at attaining the level of reasonable assurance noted above.

There have been no changes in the Company’s or Southwest’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the second quarter of 2024 that have materially affected, or are likely to materially affect the Company’s internal control over financial reporting.
