Slide 20 Efficacy and Safety Analysis of Per Protocol Patient Population • Icovamenib met the primary endpoint, displaying a clinically meaningful and statistically significant placebo-corrected reduction in HbA1c in the prespecified Per Protocol Patient population • Icovamenib was well tolerated with no study drug discontinuations due to TEAEs • Icovamenib displayed the greatest statistically significant mean HbA1c reduction in Patients dosed for 12 weeks and in the T2D subtypes characterized by insulin-deficiency. o SIDD (Arms B and C combined) mean HbA1c reduction = 1.17% o SIDD (Arm B) mean HbA1 reduction = 1.47% • Icovamenib demonstrated also a clinically meaningful reduction in HbA1c in the T2D subtype characterized by insulin resistance (MOD), in study participants uncontrolled on a GLP-1 RA-based therapy at baseline COVALENT-111 Topline Results - Conference Call December 17, 2024

Slide 22 Typical Treatment Sequence/Stacking of Therapeutics in Type 2 Diabetes COVALENT-111 Topline Results - Conference Call December 17, 2024 • Initiation of therapy typically begins with an oral anti-diabetic drugs, like metformin, added/followed by DPP-4 Inhibitors, SGLT2 Inhibitors and oral / injectable GLP-1 based therapies • Once all drugs and drug combinations are no longer supporting the patient then injection of pure insulin is the only available treatment ~30% of T2D patients take insulin

Slide 23 Type 2 Diabetes – Phenotypic Subtypes COVALENT-111 Topline Results - Conference Call December 17, 2024 Fig. The phenotype characteristics were identified using five clinical parameters (age at diabetes onset, HbA1c, BMI, and measures of insulin resistance (HOMA2-IR) and insulin secretion (HOMA2-B)) to cluster adult-onset diabetes patients into four subtypes. These subtypes are associated with different risks of complications, comorbidities, genetic factors, and responses to treatment and may provide a framework for personalized and precision medicine in diabetes.
