Forward-Looking Information

The following discussion of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the notes to those financial statements appearing elsewhere in this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025 which was filed with the U.S. Securities and Exchange Commission, or the SEC, on February 26, 2026, or the 2025 Annual Report on Form 10-K. This discussion contains forward-looking statements that involve significant risks and uncertainties. As a result of many factors, such as those set forth under “Note Regarding Forward-Looking Statements,” in this Quarterly Report on Form 10-Q, under “Part I, Item 1A—Risk Factors” in our 2025 Annual Report on Form 10-K, our actual results may differ materially from those anticipated in these forward-looking statements.

Overview

We are a biotechnology company developing and commercializing life-changing therapies for people living with gastrointestinal, or GI, and rare diseases. We are focused on the development and commercialization of innovative product opportunities in areas of significant unmet need, leveraging our demonstrated expertise and capabilities in GI and rare diseases.

LINZESS® (linaclotide), our commercial product, is the first product approved by the United States Food and Drug Administration, or U.S. FDA, in a class of GI medicines called guanylate cyclase type C agonists, or GC-C agonists, and is indicated, in the U.S., for the treatment of irritable bowel syndrome with constipation, or IBS-C, in adults and pediatric patients 7 years of age and older, chronic idiopathic constipation, or CIC, in adults, and functional constipation, or FC, in pediatric patients ages 6-17 years-old. LINZESS is also available for the treatment of adults with IBS-C or CIC in Mexico and Kingdom of Saudi Arabia, adults with IBS-C or chronic constipation in Japan, and adults with IBS-C in China. Linaclotide is available under the trademarked name CONSTELLA® for the treatment of adults with IBS-C or CIC and pediatric patients ages 6-17 years old with FC in Canada, and to adults with IBS-C in certain European countries.

We have strategic partnerships with leading pharmaceutical companies to support the development and commercialization of linaclotide throughout the world, including with our partner, AbbVie Inc., or together with its affiliates, AbbVie, in the U.S. and all countries worldwide other than China (including Hong Kong and Macau) and Japan, AstraZeneca AB or together with its affiliates, AstraZeneca in China (including Hong Kong and Macau), and Astellas Pharma Inc., or Astellas, in Japan.

We are also advancing apraglutide, a next-generation, synthetic long-acting peptide analog of glucagon-like peptide-2, or GLP-2, for short bowel syndrome, or SBS, patients who are dependent on parenteral support, or PS. In February 2024, we announced positive topline results from our pivotal Phase III clinical trial, STARS, which evaluated the efficacy and safety of once-weekly subcutaneous apraglutide in reducing parenteral support dependency in adult patients with short bowel syndrome with intestinal failure, or SBS-IF. We are also conducting an open-label extension study, STARS Extend, to further assess the safety of apraglutide in adult patients with SBS-IF. In April 2025, we announced that, based on discussions with the U.S. FDA, a confirmatory Phase III clinical trial is needed to seek approval of a new drug application or NDA, for apraglutide for patients with SBS-IF who are dependent on PS. In the fourth quarter of 2025, we met with the U.S. FDA and aligned on key design elements of a confirmatory Phase III clinical trial, STARS-2, of apraglutide. Site initiations are expected to begin in the second quarter of 2026.

To date, we have dedicated a majority of our activities to the research, development and commercialization of linaclotide, as well as other research and development programs, including apraglutide. For the three months ended March 31, 2026 and 2025, we recorded net income of $40.8 million and a net loss of $37.4 million, respectively. As of March 31, 2026, we had an accumulated deficit of approximately $1.6 billion. We are unable to predict the extent of any future losses or guarantee that our company will be able to generate and maintain positive cash flows.

We were incorporated in Delaware on January 5, 1998 as Microbia, Inc. On April 7, 2008, we changed our name to Ironwood Pharmaceuticals, Inc. We operate in one reportable business segment—human therapeutics.

Financial Operations Overview

Revenues. Our revenues are generated primarily through our collaborative arrangements and license agreements related to research and development and commercialization of linaclotide.

The majority of our revenues are generated from the sales of LINZESS in the U.S. We record our share of the net profits and losses from the sales of LINZESS in the U.S. less commercial expenses on a net basis and present the settlement payments to and from AbbVie as collaboration expense or collaborative arrangements revenue, as applicable. Net profits or losses consist of net sales to third-party customers and sublicense income in the U.S. less the cost of goods sold as well as selling, general and administrative expenses. Although we expect net sales to increase over time, the settlement payments between AbbVie and us, resulting in collaborative arrangements revenue or collaboration expense, are subject to fluctuation based on the ratio of selling, general and administrative expenses incurred by each party. In addition, our collaborative arrangements revenue may fluctuate as a result of the timing and amount of license fees and clinical and commercial milestones received and recognized under our current and future strategic partnerships as well as timing and amount of royalties from the sales of linaclotide in markets outside the U.S. where linaclotide is commercialized.

Research and Development Expenses. The core of our research and development strategy is to leverage our demonstrated expertise and capabilities in GI and rare diseases to bring medicines to patients. Research and development expenses consist of expenses incurred in connection with the research into and development of products and product candidates. These expenses consist primarily of compensation, benefits and other employee-related expenses, research and development related facility costs, third-party contract costs relating to nonclinical study and clinical trial activities, development of manufacturing processes, regulatory registration of third-party manufacturing facilities, and licensing fees for our product candidates.

Research and development expenses include amounts owed to AbbVie on an ongoing basis under cost-sharing

provisions in our collaboration agreement for linaclotide. Reimbursements received for research and development activities under this agreement are netted against research and development expenses.

Apraglutide. In February 2024, we announced positive topline results from our pivotal Phase III clinical trial, STARS, which evaluated the efficacy and safety of once-weekly subcutaneous apraglutide in reducing PS dependency in adult patients with SBS-IF. SBS-IF, a rare and severe organ failure condition in which patients are dependent on PS, affects an estimated 18,000 adult patients in the U.S., Europe, and Japan. We are also conducting an open-label extension study, STARS Extend, to further assess the safety of apraglutide in adult patients with SBS-IF. In April 2025, we announced that, based on discussions with the U.S. FDA, a confirmatory Phase III clinical trial is needed to seek approval of an NDA for apraglutide for patients with SBS-IF who are dependent on PS. In the fourth quarter of 2025, we met with the U.S. FDA and aligned on key design elements of a confirmatory Phase III clinical trial, STARS-2, of apraglutide. Site initiations are expected to begin in the second quarter of 2026.

Linaclotide. Our commercial product, LINZESS, is commercially available in the U.S. for the treatment of IBS-C in adults and pediatric patients 7 years of age and older, CIC in adults and FC in pediatric patients ages 6-17 years-old. Linaclotide is also available to adults suffering from IBS-C or CIC in certain countries of the world, including China, Japan, and in a number of European countries.

We and AbbVie continue to explore ways to enhance the clinical profile of LINZESS by studying linaclotide in additional indications, populations and formulations to assess its potential to treat various conditions. In September 2020, based on the Phase IIIb data of linaclotide 290 mcg on the overall abdominal symptoms of bloating, pain and discomfort in adult patients with IBS-C, the U.S. FDA approved our supplemental new drug application to include a more comprehensive description of the effects of LINZESS in its approved label.

In addition, we and AbbVie have established a nonclinical and clinical post-marketing plan with the U.S. FDA to understand the safety and efficacy of LINZESS in pediatric patients. In August 2021, the U.S. FDA approved a revised label for LINZESS based on clinical safety data that had been generated thus far in pediatric studies. The updated label modified the boxed warning for risk of serious dehydration and contraindication against use in children to those less than two years of age. The boxed warning and contraindication previously applied to all children less than 18 years of age and less than 6 years of age, respectively. In June 2023, the U.S. FDA approved LINZESS as a once-daily treatment for pediatric patients ages 6-17 years-old with FC, making LINZESS the first and only U.S. FDA-approved prescription therapy for FC in this patient population. On October 15, 2025, the U.S. FDA granted us a pediatric exclusivity for studies conducted on linaclotide, and in November 2025, approved LINZESS for pediatric patients 7 years of age and older with IBS-C. Additional clinical pediatric programs in FC are ongoing.

IW-3300. We were developing IW-3300, a GC-C agonist, for the potential treatment of visceral pain conditions, such as interstitial cystitis and bladder pain syndrome, or IC/BPS. In April 2025, based on analysis of the Phase II data, we decided to cease developing IW-3300 for IC/BPS.

CNP-104. Through a collaboration and license option agreement, or the COUR Collaboration Agreement, we and COUR Pharmaceutical Development Company, Inc., or COUR, were developing CNP-104 for the treatment of PBC, a rare autoimmune disease targeting the liver. In the third quarter of 2024, we received from COUR the topline data from COUR’s Phase II Clinical study for the treatment of PBC. In September 2024, we notified COUR of our decision not to exercise the option to acquire an exclusive license to CNP-104. As a result, the COUR Collaboration Agreement has terminated, and we retain no rights and have no obligations related to CNP-104.

Early research and development. Our early research and development efforts have been focused on supporting our development stage GI and rare diseases programs, including exploring strategic options for further development of certain of our internal programs, as well as evaluating external development-stage programs.

The following table sets forth our research and development expenses related to our product pipeline for the three months ended March 31, 2026 and 2025, respectively. These expenses relate primarily to compensation, benefits and other employee-related expenses and external costs associated with nonclinical studies and clinical trial costs for our product candidates. We allocate costs related to facilities, depreciation, share-based compensation, research and development support services and certain other costs directly to programs.

​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2026 ​ ​ ​ ​ ​ ​ 2025
Apraglutide ​ $18,564 ​ $19,277
Linaclotide(1) ​ ​ ​ ​ 2,433 ​ ​ 3,928

(1) Includes linaclotide in all indications, populations and formulations.

We and AbbVie are exploring development opportunities to enhance the clinical profile of LINZESS by studying linaclotide in additional indications, populations and formulations to assess its potential to treat various conditions. We cannot currently estimate with any degree of certainty the amount of time or money that we will be required to expend in the future on linaclotide for additional indications, populations or formulations.

The lengthy process of securing regulatory approvals for product candidates, including apraglutide, requires the expenditure of substantial resources. Any failure by us to obtain, or any delay in obtaining, regulatory approvals would materially adversely affect our product development efforts and our business overall. Given the inherent uncertainties that come with the development of pharmaceutical products, we cannot estimate with any degree of certainty how our programs will evolve, and therefore the amount of time or money that would be required to obtain regulatory approval to market them.

As a result of these uncertainties surrounding the timing and outcome of any approvals, we are currently unable to estimate precisely when, if ever, linaclotide’s utility will be expanded within its currently approved indications; if or when linaclotide will be developed outside of its current markets, indications, populations or formulations; or when, if ever, apraglutide or any of our other product candidates will generate revenues and cash flows.

We invest carefully in our pipeline, and the commitment of funding for each subsequent stage of our development programs is dependent upon the receipt of clear, supportive data. In addition, we intend to access externally discovered drug candidates that fit within our core strategy. In evaluating these potential assets, we apply the same investment criteria as those used for investments in internally discovered assets.

The successful development of our product candidates is highly uncertain and subject to a number of risks including, but not limited to:

  • The duration of clinical trials may vary substantially according to the type, complexity and novelty of the product candidate;
  • The U.S. FDA and comparable foreign agencies impose substantial and varying requirements on the introduction of therapeutic pharmaceutical products, typically requiring lengthy and detailed laboratory and clinical testing procedures, sampling activities and other costly and time-consuming procedures;
  • Data obtained from nonclinical and clinical activities at any step in the testing process may be adverse and lead to discontinuation or redirection of development activity. Data obtained from these activities also are susceptible to varying interpretations, which could delay, limit or prevent regulatory approval;
  • The U.S. FDA and comparable foreign agencies may require additional clinical trials and other studies, which may be costly or delay, limit, prevent or otherwise impact regulatory submission or approval;
  • The duration and cost of early research and development, including nonclinical studies and clinical trials, may vary significantly over the life of a product candidate and are difficult to predict;
  • The costs, timing and outcome of regulatory review of a product candidate may not be favorable, and, even if approved, a product may face post-approval development and regulatory requirements;
  • There may be substantial costs, delays and difficulties in successfully integrating externally developed product candidates into our business operations; and
  • The emergence of competing technologies and products and other adverse market developments may negatively impact us.

As a result of the factors discussed above, including the factors discussed under “Note Regarding Forward-Looking Statements” in this Quarterly Report on Form 10-Q, and under “Part I, Item 1A – Risk Factors” in our 2025 Annual Report on Form 10-K, we are unable to determine the duration and costs to complete current or future nonclinical and clinical stages of our product candidates or when, or to what extent, we will generate revenues from the commercialization and sale of our product candidates. Development timelines, probability of success and development costs vary widely. We anticipate that we will make determinations as to which additional programs to pursue and how much funding to direct to each program on an ongoing basis in response to the data of each product candidate, the competitive landscape and ongoing assessments of such product candidate’s commercial potential.

We expect to invest in our development programs and incur substantial research and development expenses for the foreseeable future. We will continue to invest in linaclotide, including the investigation of ways to enhance the clinical profile within its currently approved indications, and the exploration of its potential utility in other indications, populations and formulations, and in apraglutide, as we advance it through clinical trials, in addition to funding research and development activities under our external collaboration and license agreements with respect to our products and product candidates.

Selling, General and Administrative Expense. Selling, general and administrative expense consists primarily of compensation, benefits and other employee-related expenses for personnel in our administrative, finance, legal, information technology, business development, commercial, sales, marketing, communications and human resource functions. Other costs include legal costs of pursuing patent protection of our intellectual property, general and administrative related facility costs, insurance costs and professional fees for accounting, tax, consulting, legal and other services. As we continue to invest in the development and commercialization of LINZESS, apraglutide and other product candidates, we expect our selling, general and administrative expenses will be substantial for the foreseeable future.

We include AbbVie’s selling, general and administrative cost-sharing payments in the calculation of the net profits and net losses from the sale of LINZESS in the U.S. and present the net payment to or from AbbVie as collaboration expense or collaborative arrangements revenue, respectively.

Restructuring Expenses. Restructuring expenses primarily pertain to workforce reductions in January 2025 consisting primarily of field-based sales employees and August 2025 consisting of certain positions supporting apraglutide commercialization efforts. The workforce reduction and restructuring initiatives are more fully described in Note 11, Workforce Reductions and Restructuring, to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Interest Expense and Other Financing Costs. Interest expense consists primarily of cash and non-cash interest costs related to our 2026 Convertible Notes and our $550.0 million secured revolving credit facility, or the Revolving Credit Facility. Non-cash interest expense consists of amortization of debt issuance costs.

Interest and Investment Income. Interest and investment income consists of interest earned on our cash and cash equivalents.

Income Taxes. We prepare our income tax provision based on our interpretation of the income tax accounting rules and each jurisdiction’s enacted tax laws and regulations. As of interim reporting dates, we record our income tax provision by applying our estimated annual effective tax rate to year-to-date pre-tax income, plus adjustments for significant discrete items.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make certain estimates and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of assets and liabilities as of the date of the condensed consolidated financial statements, and the amounts of revenues and expenses during the reported periods. We base our estimates on our historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ materially from our estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known.

During the three months ended March 31, 2026, there were no material changes to our critical accounting policies as reported in our 2025 Annual Report on Form 10-K.

​ ​ ​ ​ ​ Revenues: ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2026 ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change $ ​ ​
Collaborative arrangements revenue ​ ​ ​ $106,506 ​ ​ ​ $41,143 ​ ​ ​ $65,363
Total revenues ​ $106,506 ​ $41,143 ​ $65,363

Collaborative arrangements revenue. The increase in collaborative arrangements revenue of $65.4 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 was primarily related to a $65.5 million increase in our share of net profits from the sale of LINZESS in the U.S., which was driven primarily by increased net price, as well as inventory channel fluctuations and increased prescription demand.

Costs and Expenses

(in thousands)

​ ​ ​ ​ ​ Costs and expenses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2026 ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change $ ​ ​
Research and development ​ $21,940 ​ $27,432 ​ $(5,492)

Restructuring, net ​ ​ (40) ​ ​ 18,559 ​ ​ (18,599)
Total costs and expenses ​ $33,933 ​ $70,251 ​ $(36,318)

Research and development. The decrease in research and development expenses of $5.5 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 was primarily related to $1.4 million decrease in external costs associated with the IW-3300 development program, a $1.0 million decrease in external costs associated with the linaclotide program, a $0.9 million decrease in external costs associated with the apraglutide program, and a $0.5 million decrease in compensation, benefits, and other employee-related expenses.

Selling, general and administrative. Selling, general and administrative expenses decreased by $12.2 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025, primarily due to a $6.4 million decrease in compensation, benefits, and other employee-related expenses and a $0.9 million decrease in sales and marketing expenses, both resulting from the restructuring initiatives during 2025, as well as a decrease of $5.3 million in professional services expenses.

Restructuring expenses. The decrease in restructuring expense of $18.6 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 is primarily related to the workforce reduction in January 2025 consisting primarily of field-based employees. Workforce reduction and restructuring initiatives are more fully described in Note 11, Workforce Reductions and Restructuring, to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Other Income (Expense), Net

(in thousands)

​ ​ ​ ​ ​ Other income (expense): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2026 ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Change $ ​ ​
Interest expense and other financing costs ​ $(9,141) ​ $(8,070) ​ $(1,071)

Other ​ 42 ​ 37 ​ 5
Total other income (expense), net ​ $(7,401) ​ $(7,164) ​ $(237)

Interest expense and other financing costs. Interest expense and other financing costs increased by $1.1 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025, primarily due to professional services incurred in connection with potential financing transactions, partially offset by lower interest rates on the Revolving Credit Facility throughout the period.

Interest and investment income. Interest and investment income increased by $0.8 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 due to an increase in cash and cash equivalents balances, partially offset by a decrease in interest rates.

Other. During each of the three months ended March 31, 2026 and 2025, we recorded a gain of an insignificant amount for pension-related activities.

Income taxes. For the three months ended March 31, 2026 and 2025, we recorded income tax expense of $24.4 million and $1.1 million, respectively. Due to our ability to utilize our net operating losses and research and development credits to offset the majority of federal taxable income and taxable income in most states, the majority of our tax provision will be a non-cash expense.

Liquidity and Capital Resources

As of March 31, 2026, we had $220.5 million of cash and cash equivalents. Our cash equivalents include amounts held in money market funds, U.S. Treasury securities and commercial paper. We invest cash in excess of immediate requirements in accordance with our investment policy, which limits the amounts we may invest in certain types of investments and requires all investments held by us to be at least A- rated, with a remaining final maturity when purchased of less than twenty-four months, so as to primarily achieve liquidity and capital preservation objectives.

We anticipate our cash and cash equivalents balance, our expected net cash inflows from operations, our borrowing capacity on our Revolving Credit Facility, and/or additional capital sources to allow us to meet our short-term and long-term cash obligations, which are reflected in our condensed consolidated balance sheets. Our most significant fixed obligations are debt obligations and lease commitments, for which annual payments are disclosed in Note 8, Debt, and Note 6, Leases, respectively, to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, as well as supply purchase commitments, for which the obligations are disclosed in Note 10, Commitments and Contingencies, in our 2025 Annual Report on Form 10-K.

We may from time to time seek to retire, redeem or repurchase all or part of our outstanding debt through cash purchases and/or exchanges, in open market purchases, privately negotiated transactions, by tender offer or otherwise. Such repurchases, redemptions or exchanges, if any, of our debt will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors, and the amounts involved may be material.

Sources of Liquidity

We have financed our operations to date primarily through both the private sale of our preferred stock and the public sale of our common stock, debt financings, and cash generated from our operations. As of March 31, 2026, our debt is comprised of $200.0 million aggregate principal amount of convertible notes, due in June 2026, and $385.0 million aggregate principal amount outstanding under our Revolving Credit Facility, which we entered into in May 2023 to partially finance our acquisition of VectivBio Holding AG in June 2023. The Revolving Credit Facility provides for $550.0 million of borrowing capacity and includes a $10.0 million letter of credit subfacility. Refer to Note 8, Debt, to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for information related to our debt obligations.

Summary of Cash Flows

The following table summarizes cash flows from operating, investing, and financing activities for the three months ended March 31, 2026 and 2025:

(in thousands)

​ ​ ​ ​ ​ Net cash provided by (used in): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2026 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​
Operating activities ​ $5,121 ​ $19,954
Investing activities ​ ​ — ​ ​ (31)
Financing activities ​ ​ — ​ ​ 6
Effect of exchange rate changes on cash and cash equivalents ​ ​ (106) ​ ​ (7)
Net increase in cash and cash equivalents ​ $5,015 ​ $19,922

Cash Flows from Operating Activities

Net cash provided by operating activities is derived by adjusting net income (loss) for non-cash items and changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in the results of operations.

Net operating cash inflows for the three months ended March 31, 2026 and 2025 totaled $5.1 million and $20.0 million, respectively, and were derived primarily from collaboration arrangements revenue related to sales of LINZESS in the U.S.

Cash Flows from Investing Activities

Cash used in investing activities for the three months ended March 31, 2025 was insignificant and pertained to the purchase of property and equipment.

Cash Flows from Financing Activities

Cash provided by financing activities for the three months ended March 31, 2025 was insignificant and was generated by employee equity transactions.

Funding Requirements

We began commercializing LINZESS in the U.S. with our collaboration partner, AbbVie, in the fourth quarter of 2012, and we currently derive a significant portion of our revenue from this collaboration. Our goal is to generate and maintain positive cash flows, driven by increased revenue generated through sales of LINZESS and other commercial activities and financial discipline, while continuing to invest in the development and commercialization of linaclotide, apraglutide, and other product candidates.

Under our collaboration with AbbVie for North America, total net sales of LINZESS in the U.S., as recorded by AbbVie, are reduced by commercial costs incurred by each party, and the resulting amount is shared equally between us and AbbVie. Additionally, we receive royalties from AbbVie based on sales of linaclotide in its licensed territories outside of the U.S. We believe revenues from our LINZESS partnership for the U.S. with AbbVie will continue to constitute a significant portion of our total revenue for the foreseeable future and we cannot be certain that such revenues, as well as the revenues from our other commercial activities, will continue to enable us to generate positive cash flows, or to do so in the timeframes we expect. We also anticipate that we will continue to incur substantial expenses for the next several years as we further develop and commercialize linaclotide in the U.S., develop and commercialize other product candidates, including apraglutide, and invest in building our pipeline through internal or external opportunities. We believe that our cash and cash equivalents on hand as of March 31, 2026, our expected cash inflows from operations, and our borrowing capacity on our Revolving Credit Facility will be sufficient to meet our projected operating needs at least through the next twelve months from the issuance of these financial statements. We have short-term and long-term debt obligations, including convertible notes that mature on June 15, 2026, which are disclosed in Note 8, Debt, to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. There is no assurance we will have sufficient liquidity to meet our debt obligations when they become due.

Our forecast of the period of time through which our financial resources will be adequate to support our operations, including the underlying revenue expectations and estimates regarding the costs to continue to develop, obtain regulatory approval for, and commercialize linaclotide in the U.S., develop and commercialize other product candidates, including apraglutide, and our goal to generate and maintain positive cash flows, are forward-looking statements that involve risks and uncertainties. Our actual results could vary materially and negatively from these and other forward-looking statements as a result of a number of factors, including the factors discussed under the headings “Note Regarding Forward-Looking Statements” in this Quarterly Report on Form 10-Q and under “Part I, Item 1A—Risk Factors” in our 2025 Annual Report on Form 10-K. We have based our estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

Due to the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate precisely the amounts of capital outlays and operating expenditures necessary to develop, obtain regulatory approval for, and commercialize linaclotide, apraglutide and our other product candidates, in each case, for all of the markets, indications, populations and formulations for which we believe each is suited. Our funding requirements will depend on many factors, including, but not limited to, the following:

  • the revenue generated by sales of LINZESS and CONSTELLA and from any other sources;
  • the rate of progress and cost of our commercialization activities, including the expense we incur in marketing and selling LINZESS in the U.S. and from any other sources;
  • the success of our third-party manufacturing activities;
  • the time and costs involved in developing, and obtaining regulatory approvals for, our product candidates, including apraglutide, as well as the timing and cost of any post-approval development and regulatory requirements;
  • the time and costs associated with commercial manufacturing, sales, marketing and distribution of apraglutide, if approved;
  • the success of our research and development efforts;
  • the emergence of competing or complementary products;
  • the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
  • the terms and timing of any collaborative, licensing or other arrangements that we may establish, including milestones, royalties or other payments due or payable under such agreements;
  • the settlement method used for our outstanding convertible notes; and
  • the acquisition of businesses, products and technologies and the impact of other strategic transactions, as well as the cost and timing of evaluating, acquiring, and, if completed, integrating into our business operations any such assets.

Financing Strategy

We may, from time to time, consider additional funding through a combination of new collaborative arrangements, strategic alliances, and additional equity and debt financings or from other sources. We will continue to manage our capital structure and to consider all financing opportunities, whenever they may occur, that could strengthen our long-term liquidity profile. Any such capital transactions may or may not be similar to transactions in which we have engaged in the past. There can be no assurance that any such financing opportunities will also be available on acceptable terms, if at all.

Controls and procedures

As filed, 2,637 characters, with its headings, lists and tables. Extracted from the main document; charts and exhibits are in the original on sec.gov.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, or Exchange Act, our management, including our principal executive officer and our principal financial officer, conducted an evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q of the effectiveness of the design and operation of our disclosure controls and procedures. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such date are effective at the reasonable assurance level in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

As required by Rule 13a-15(d) of the Exchange Act, our management, including our principal executive officer and our principal financial officer, conducted an evaluation of the internal control over financial reporting to determine whether any changes occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Based on management’s evaluation, our principal executive officer and principal financial officer concluded no changes during the period covered by this Quarterly Report on Form 10-Q materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.
