T HE OP P OR T UN I T Y Ifetroban: A De-Risked Molecule with Multiple Commercial Opportunities Cumberland Pharmaceuticals | Nasdaq: CPIX 4 Positive Phase 2 DMD Data Ifetroban improved heart function vs. a declining natural-history course — addressing a leading cause of death in Duchenne muscular dystrophy patients. Well-Established Safety Profile ~1,400 subjects dosed across ~30 clinical studies, providing a well-characterized safety profile. Key FDA Designations Orphan Drug, Rare Pediatric Disease and Fast Track designations; FDA granted rolling review of the planned NDA. Platform Opportunity One molecule across DMD, SSc and IPF, plus other expansion programs. Proven Approval Track Record A team with a strong history of prior FDA drug approvals — experience that de-risks ifetroban's path to market. Well-Capitalized Balance sheet strengthened by a ~$100M+ divestiture of the company's commercial assets, with no debt. Three core clinical programs, one core molecule: three ifetroban Phase 2 indications, now supported by a shared ~1,400-subject safety database.

Blocking this single receptor interrupts three injury pathways at once. Targets inflammatory signaling Antagonizes TPr-mediated immune and inflammatory signaling that has been implicated in tissue injury. Targets fibrosis (scarring) Fibrotic scarring contributes to progression in DMD, SSc and IPF; reducing TPr- driven injury is intended to slow it. Relaxes blood vessels Inhibits smooth-muscle contraction and platelet aggregation, improving perfusion to affected tissue. One target, many tissues: a shared, targetable pathway supports developing one molecule across DMD, SSc and IPF. Mechanism adapted from Capra, J Thromb Haemost 2014.

M E C H A N I S M O F A C T I O N How Ifetroban Protects the Heart The problem DMD gene mutation leads to weakened muscle cells resulting in calcium overload in heart cells, oxidative stress, cardiomyocyte death and progressive cardiac fibrosis. The target Ifetroban is a potent, selective antagonist of the thromboxane receptor (TPr) expressed on cardiomyocytes, immune, smooth-muscle and endothelial cells. The effect By blocking damaging TPr signaling, ifetroban reduces cell damage — resulting in less fibrosis and less loss of heart function over time. The evidence base Safety established in ~1,400 subjects across ~30 studies; once-daily oral dosing. Adapted from Capra, J Thromb Haemost 2014. 12 Calcium overload in heart cells Ifetroban Cumberland Pharmaceuticals | Nasdaq: CPIX
