Ironwood Pharmaceuticals Initiates Apraglutide NDASubmission, Highlights Compelling New Data and UpdatesCorporate Structure to Position for the Future January 29, 2025 – – – – - BOSTON (BUSINESS WIRE) Ironwood Pharmaceuticals, Inc. (Nasdaq: IRWD), a biotechnology company developing and commercializing life-changing therapies for people living with gastrointestinal (GI) and rare diseases, today announced a streamlined strategic focus on advancing and realizing the potential of apraglutide for the treatment of short bowel syndrome (“SBS”) patients who are dependent on parenteral support. In line with this strategic update, Ironwood will be reducing its workforce by approximately 50%. This reorganization is intended to position the company for long-term growth. “Ironwood’s long track record of success stems from our ability to be nimble as an organization by focusing on both signi cant medical needs and nancial performance. While LINZESS continues to grow prescription demand, given the impact of ongoing pricing pressures, we are taking steps to reduce Ironwood costs that are predominantly associated with the brand. By doing so, we believe we can continue to generate pro ts and cash ows and support the successful development of apraglutide. LINZESS remains an important part of our strategy, along with continued investment in apraglutide for SBS patients who are dependent on parenteral support, which we believe will deliver value to our stakeholders and ultimately bring a new therapy to patients with great unmet need,” said Tom McCourt, chief executive o cer of Ironwood. “We have made important progress by initiating our rolling new drug application (“NDA”) submission and announcing new data from our open label extension study, STARS Extend, demonstrating an increased number of patients on apraglutide achieving enteral autonomy over time. We plan to include the long-term extension data in our NDA submission, in addition to the robust e cacy and tolerability data from STARS, the largest Phase 3 clinical trial ever conducted in SBS-IF patients. With these new data, we are even more encouraged about apraglutide’s potential to help SBS patients who are dependent on parenteral support,” said Mike Shetzline, M.D., Ph.D, chief medical o cer, senior vice president and head of research and drug development at Ironwood. "Our apraglutide launch planning is well underway. Under Tammi’s leadership we have strong commercial capabilities to support the future success of apraglutide, if approved. As a rare disease therapy, this will require a very targeted promotional effort while providing a robust patient hub service model,” Mr. McCourt added.

“While the reduction in force is particularly di cult, these changes are necessary to continue to progress apraglutide and maintain our pro tability and cash ow goals, to support Ironwood’s long-term growth. I want to personally thank all the employees affected by this restructuring for their dedication to our mission and their many contributions to the company,” added Mr. McCourt. Recent Pipeline and Corporate Updates: Apraglutide Open Label Extension Study, STARS Extend: The extension study data demonstrate that more patients weaned off parenteral support with longer exposure to apraglutide. An analysis of long-term extension data also showed that 27 apraglutide-dosed patients achieved enteral autonomy, which is the ultimate goal of SBS patients who are dependent on parenteral support. Strategic Reorganization: Reorganization is primarily driven by the elimination of Ironwood’s eld force. Ironwood also has decided to wind down the Phase 2 exploratory study, STARGAZE, of apraglutide in Graft-versus- Host Disease to further focus its resources and investments. Ironwood expects to incur restructuring charges of approximately $20 to $25 million, which are anticipated to be incurred primarily in the rst half of 2025. Ironwood expects to realize, as a result of the strategic reorganization, approximately $55 to $60 million of annual operating expense savings, resulting in $40 to $45 million bene t to annual pro ts, net of impact to collaborative arrangements revenue. Leadership Updates: Greg Martini has been promoted to Senior Vice President, Chief Financial O cer. Greg joined Ironwood in 2017 and has served in roles of increasing responsibility, most recently as Vice President, Strategic Finance and Investor Relations since 2022. Tammi Gaskins has been appointed Senior Vice President, Chief Commercial O cer. Tammi joined Ironwood in 2020 and has been integral in shaping the apraglutide commercial launch plan and driving the performance of LINZESS. Prior to joining Ironwood, Tammi spent 20 years at AstraZeneca in various commercial leadership positions across different therapeutic areas. Full Year 2025 Financial Guidance: Ironwood is providing FY 2025 nancial guidance. FY 2025 Guidance (January 2025) LINZESS U.S. net sales $800 - $850 million High single digit prescription demand growth, more than offset by expected price erosion due to Medicare Part D redesign Total revenue $260 - $290 million Adjusted EBITDA >$85 million Ironwood’s U.S. collaborative arrangements revenue includes reimbursement from AbbVie for a portion of Ironwood’s commercial expenses related to sales of LINZESS in the U.S. The FY2025 total revenue guidance accounts for the impact of the reduction to Ironwood’s commercial expenses and corresponding reimbursement from AbbVie due to Ironwood’s strategic reorganization. 1 2 1

Adjusted EBITDA is calculated by subtracting restructuring expenses, net interest expense, income taxes, depreciation and amortization and stock-based compensation, from GAAP net income. The exclusion of stock-based compensation from Adjusted EBITDA represents an update to our de nition of Adjusted EBITDA, effective in the rst quarter of 2025. For purposes of this guidance, we have assumed that Ironwood will not incur material expenses related to business development activities in 2025. Ironwood does not provide guidance on GAAP net income or a reconciliation of expected adjusted EBITDA to expected GAAP net income because, without unreasonable efforts, it is unable to predict with reasonable certainty the non-GAAP adjustments used to calculate adjusted EBITDA. These adjustments are uncertain, depend on various factors and could have a material impact on GAAP net income for the guidance period. Management believes this non-GAAP information is useful for investors, taken in conjunction with Ironwood’s GAAP nancial statements, because it provides greater transparency and period-over-period comparability with respect to Ironwood’s operating performance. These measures are also used by management to assess the performance of the business. Investors should consider these non-GAAP measures only as a supplement to, not as a substitute for or as superior to, measures of nancial performance prepared in accordance with GAAP. In addition, these non-GAAP nancial measures are unlikely to be comparable with non-GAAP information provided by other companies.

Ironwood is advancing apraglutide, a next-generation, long-acting synthetic GLP-2 analog being developed for short bowel syndrome patients who are dependent on parenteral support. In addition, Ironwood has been a pioneer in the development of LINZESS® (linaclotide), the U.S. branded prescription market leader for adults with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC). LINZESS is also approved for the treatment of functional constipation in pediatric patients ages 6-17 years old. Building upon our history of innovation, we keep patients at the heart of our R&D and commercialization efforts to reduce the burden of diseases and address signi cant unmet needs.

LINZESS is a once-daily capsule that helps relieve the abdominal pain, constipation and overall abdominal symptoms of bloating, discomfort and pain associated with IBS-C, as well as the constipation, infrequent stools, hard stools, straining and incomplete evacuation associated with CIC. LINZESS relieves constipation in children and adolescents aged 6 to 17 years with functional constipation. The recommended dose is 290 mcg for IBS-C patients and 145 mcg for CIC patients, with a 72 mcg dose approved for use in CIC depending on individual patient presentation or tolerability. In children with functional constipation aged 6 to 17 years, the recommended dose is 72 mcg. LINZESS is not a laxative; it is the rst medicine approved by the FDA in a class called GC-C agonists. LINZESS contains a peptide called linaclotide that activates the GC-C receptor in the intestine. Activation of GC-C is thought to result in increased intestinal uid secretion and accelerated transit and a decrease in the activity of pain-sensing nerves in the intestine. The clinical relevance of the effect on pain bers, which is based on nonclinical studies, has not been established. In the United States, Ironwood and AbbVie co-develop and co-commercialize LINZESS for the treatment of adults with IBS-C or CIC. In Europe, AbbVie markets linaclotide under the brand name CONSTELLA® for the treatment of adults with moderate to severe IBS-C. In Japan, Ironwood's partner, Astellas, markets linaclotide under the brand name LINZESS for the treatment of adults with IBS-C or CIC. Ironwood also has partnered with AstraZeneca for development and commercialization of LINZESS in China, and with AbbVie for development and commercialization of linaclotide in all other territories worldwide. LINZESS Important Safety Information INDICATIONS AND USAGE LINZESS® (linaclotide) is indicated for the treatment of both irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in adults and functional constipation (FC) in children and adolescents 6 to 17 years of age. It is not known if LINZESS is safe and effective in children with FC less than 6 years of age or in children with IBS-C less than 18 years of age. IMPORTANT SAFETY INFORMATION WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS LESS THAN 2 YEARS OF AGE LINZESS is contraindicated in patients less than 2 years of age. In nonclinical studies in neonatal mice, administration of a single, clinically relevant adult oral dose of linaclotide caused deaths due to dehydration. Contraindications LINZESS is contraindicated in patients less than 2 years of age due to the risk of serious dehydration. LINZESS is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction. Warnings and Precautions LINZESS is contraindicated in patients less than 2 years of age. In neonatal mice, linaclotide increased uid secretion as a consequence of age-dependent elevated guanylate cyclase (GC-C) agonism, which was associated with increased mortality within the rst 24 hours due to dehydration. There was no age dependent trend in GC-C intestinal expression in a clinical study of children 2 to less than 18 years of age; however, there are insu cient data available on GC-C intestinal expression in children less than 2 years of age to assess the risk of developing diarrhea and its potentially serious consequences in these patients.

In adults, diarrhea was the most common adverse reaction in LINZESS-treated patients in the pooled IBS-C and CIC double-blind placebo-controlled trials. The incidence of diarrhea was similar in the IBS-C and CIC populations. Severe diarrhea was reported in 2% of 145 mcg and 290 mcg LINZESS-treated patients and in <1% of 72 mcg LINZESS-treated CIC patients. In children and adolescents 6 to 17 years of age, diarrhea was the most common adverse reaction in 72 mcg LINZESS-treated patients in the FC double-blind placebo-controlled trial. Severe diarrhea was reported in <1% of 72 mcg LINZESS treated patients. If severe diarrhea occurs, dosing should be suspended and the patient rehydrated. Common Adverse Reactions (incidence ≥ 2% and greater than placebo) In IBS-C or CIC adult patients: diarrhea, abdominal pain, atulence, and abdominal distension. In FC pediatric patients: diarrhea.
