Conference call and webcast at 8:30 am ET
The Woodlands, Texas, March 5, 2026 – Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), today reported financial results for the three months and year ended December 31, 2025, and provided an update on key corporate milestones and accomplishments.
“The fourth quarter of 2025 marked the completion of an incredible year for Lexicon,” said Mike Exton, Ph.D., Lexicon’s chief executive officer and director. “We made substantial progress on all aspects of the business by advancing our pipeline programs, establishing strong development and commercialization agreements with leading global collaborators, working closely with regulators, and remaining operationally efficient. As a result, we have begun 2026 with tremendous momentum and are well-positioned to successfully execute on multiple important catalysts ahead.”
Scott Coiante, Lexicon’s senior vice president and chief financial officer, further commented, “Over the past year, we have pulled multiple levers to strengthen our financial position and extend our cash runway to support our robust clinical development pipeline. Our recent capital raise and milestone payment received from Novo Nordisk resulted in more than $100 million in additional cash in February 2026, which together with our rigorous expense discipline in 2025, provides the financial footing needed to support our pipeline programs.”
Fourth Quarter 2025 Business and Pipeline Highlights
Cardiometabolic
Sotagliflozin
Sotagliflozin is an oral inhibitor of sodium-glucose cotransporter types 1 and 2 (SGLT1 and SGLT2) and has been studied in approximately 20,000 patients across multiple cardiometabolic indications. Sotagliflozin is commercially available in the U.S. for heart failure as INPEFA®.
Hypertrophic Cardiomyopathy (HCM)
•Enrollment continues in SONATA-HCM, a pivotal Phase 3 placebo-controlled study with a targeted enrollment of 500 patients with obstructive or nonobstructive HCM.
•Lexicon has completed the initiation of 130 sites in 20 countries across the United States, Europe and Latin America.
•The study has surpassed 50 percent enrollment and Lexicon continues to expect enrollment completion in mid-2026, with topline results in the first quarter of 2027.
Type 1 Diabetes (T1D) (ZYNQUISTA®)
•Lexicon remains focused on bringing ZYNQUISTA to market for glycemic control in adults with T1D, a patient population which has not benefitted from a new treatment mechanism since the discovery of insulin.
•Based on U.S. Food and Drug Administration (FDA) feedback, Lexicon remains on track for potential New Drug Application (NDA) resubmission and regulatory approval in 2026 if the patient exposure and safety data requirements identified by the FDA are achieved by STENO1, a third-party funded, investigator-initiated study of sotagliflozin being conducted by the STENO Diabetes Center (Denmark).
Viatris License for All Indications Ex-U.S. and Ex-Europe
•Lexicon continues to support licensee Viatris in its regulatory filing and commercial strategy for sotagliflozin outside of the U.S. and Europe and in 2025 shipped the first commercial product to the United Arab Emirates, the first country to obtain approval outside of the U.S.
•Viatris submitted applications for regulatory approval in several other markets in 2025, including Canada, Australia and New Zealand, and preparations are underway by Viatris for regulatory submissions in additional ex-U.S. and ex-European markets throughout 2026.
LX9851 for Obesity and Associated Cardiometabolic Disorders
LX9851 is a first-in-class, non-incretin, oral, small molecule inhibitor of acyl-CoA synthetase 5 (ACSL5) in development by Novo Nordisk for obesity and weight management.
•All Investigational New Drug (IND) application-enabling activities were completed by Lexicon in 2025.
•In February 2026, the company received a $10 million milestone payment from Novo Nordisk, with potential for up to $20 million in additional milestone payments in 2026.
•Under the terms of Lexicon’s exclusive license agreement with Novo Nordisk, Lexicon received an upfront payment of $45 million in April 2025 and is eligible to receive up to an aggregate of $1 billion in upfront and development, regulatory and sales milestone payments. Lexicon is also eligible for tiered royalties on net sales of LX9851.
Pain
Pilavapadin (LX9211) for Diabetic Peripheral Neuropathic Pain (DPNP)
Pilavapadin is an orally delivered, small molecule drug candidate for the treatment of DPNP, among other potential indications. Pilavapadin has the potential to be the first oral, non-opioid drug therapy approved in neuropathic pain in more than 20 years.
•Lexicon and the FDA held a successful End-of-Phase 2 meeting in the fourth quarter of 2025. The FDA raised no objections to the advancement of pilavapadin into Phase 3 development, which would include two placebo-controlled, 12-week, two arm registrational studies comparing the 10 mg daily dose to placebo. The primary endpoint of the Phase 3 studies would be the change in average daily pain score (ADPS) from baseline to Week 12.
•Lexicon continues to hold partnership discussions to maximize the global potential of this investigative therapy.
Fourth Quarter 2025 Financial Highlights
Revenues: Total revenues were $5.5 million and $49.8 million for the quarter and year ended December 31, 2025, respectively. Revenues for the fourth quarter of 2025 include $4.3 million of licensing revenue from the Novo Nordisk agreement and net sales of INPEFA of $1.1 million.
Revenues for the year ended December 31, 2025, include $45 million of licensing revenue from the Novo Nordisk agreement and $4.6 million of net sales of INPEFA.
Total revenues for the fourth quarter and full year 2024 include the upfront payment of $25 million received upon entering into the Viatris license agreement and net sales of INPEFA of $1.6 million and $6.0 million, respectively.
Research and Development (R&D) Expenses: Research and development expenses for the fourth quarter of 2025 decreased to $11.3 million from $26.7 million in 2024. Full-year 2025 research and development expenses decreased to $61.1 million from $84.5 million in 2024, primarily reflecting lower external research expense on our PROGRESS clinical trial partially offset by increased investment in the SONATA Phase 3 clinical trial.
Selling, General and Administrative (SG&A) Expenses: Selling, general and administrative expenses for the fourth quarter of 2025 decreased to $8.8 million from $32.3 million in 2024. Full-year 2025 selling, general and administrative expenses decreased to $37.3 million from $143.1 million in 2024. The decrease in 2025 reflects lower costs resulting from the Company’s strategic repositioning in late 2024 and the significantly reduced marketing and promotional efforts for INPEFA in 2025.
Net Loss: Net loss for the fourth quarter of 2025 was $15.5 million, or $0.04 per share, compared to a net loss of $33.8 million, or $0.09 per share, in the corresponding period in 2024. Net loss for the full year 2025 was $50.3 million, or $0.14 per share, compared to a net loss of $200.4 million, or $0.63 per share, in the corresponding period in 2024. For the fourth quarters of 2025 and 2024, net loss included non-cash, stock-based compensation expense of $2.8 million and $1.5 million, respectively and for the full years of 2025 and 2024, net loss included non-cash, stock-based compensation expense of $12.5 million and $13.5 million, respectively.
Cash, Investments, and Restricted Cash: As of December 31, 2025, Lexicon had $125.2 million in cash, investments and restricted cash, as compared to $238.0 million in cash and investments as of December 31,2024.
In February 2026, Lexicon received approximately $96.7 million of net proceeds from the sale of common and preferred stock and also received a $10 million milestone payment from Novo Nordisk.
