BMF-650 Next-generation oral GLP-1 receptor agonist Designed for consistent exposure, higher bioavailability and improved tolerability with scalable weight reduction • Improved bioavailability, better plasma protein binding, greater oral exposure with lower variability • Demonstrated weight reduction and generally well tolerated in preclinical models • Phase I clinical study in obese healthy volunteers ongoing with 28-day weight reduction data anticipated in 2Q 26, aiming to address over 100M U.S. obese patients Critical unmet need: Real world evidence indicates that up to 70% of patients on currently available GLP-1 based therapies drop out 4 within the first year due to gastrointestinal adverse events and other tolerability considerations.

Slowing the clock on diabetes Turning a healthcare crisis into a huge opportunity The problem: Diabetes is a global healthcare crisis, with over 800 million people affected worldwide. The disease is expanding at an estimated ~4% annually. In the United States, one in every four healthcare dollars is spent on people living with diabetes, totaling ov er $400 billion per year. More than 100 million Americans have prediabetes; approximately 40% will progress to diabetes, and ~60% are diagnosed only after reaching late-stage disease. The economic impact: Late-stage diabetes drives over 50% of healthcare related costs due to complications such as kidney failure, cardiovascular disease, amputations and visual loss. With late-stage diabetes the healthcare system is burden by additional $15,000 - $20,000 per patient. Assuming 10m US diabetes patients are in late stage, delaying the progression could save the system $150-200billion. Our breakthrough: We are developing a novel mechanism of action developed to restore beta-cell function and slow the progression of hyperglycemia. By rebuilding a functional beta-cell pool, the body may regain the ability to regulate its own insulin production. The true burden of diabetes is not early disease, but late-stage progression with irreversible organ damage. Slowing that clock by even a few years could generate societal returns exceeding the annual economic output of the entire pharmaceutical sector. Icovamenib would delay the need for unwieldy and often unreliable insulin therapy for years! Our vision: Keeping diabetes patients durably controlled, preventing progression to late-stage disease and avoiding the devastating complications that drive cost, morbidity, and mortality. 36
