Ataciguat: soluble guanylate cyclase (sGC) activator in development for CAVS • Ataciguat targets valvular interstitial cells to slow osteogenic and calcific remodeling, an underlying driver of disease progression in calcific aortic valve stenosis (CAVS), and has demonstrated direct myocardial effects in improving both systolic and diastolic function, a hallmark of progressive disease that results in valvular heart failure. • Ataciguat is currently being evaluated in the Company’s KATALYST-AV Phase 2b clinical trial in CAVS patients with moderate disease. The Company expects to share Phase 2b topline data from the interim 24- week analysis in the first half of 2027. Tonlamarsen: antisense oligonucleotide in development for ASH • Tonlamarsen targets hepatic angiotensinogen (AGT) for the management of blood pressure in acute severe hypertension (ASH) post-hospitalization. • Extended follow-up data from an earlier KARDINAL clinical trial assessing the effect of Tonlamarsen in uncontrolled hypertension will be presented at the upcoming European Society of Cardiology Congress (ESC 2026). [Session: Late-Breaking Clinical Science: renin-angiotensin-aldosterone pathway inhibition; Sunday, Aug 30th from 1:45 - 3:00 PM CEST] • Tonlamarsen is currently being evaluated in the Company’s KARDINAL-ASH Phase 2 clinical trial. In the second quarter, the Company randomized the first patient in KARDINAL-ASH and expects to share Phase 2 topline data in the first half of 2027. Additional Highlights • In June, the Company announced the closing of its initial public offering with aggregate gross proceeds of $460 million (before deducting underwriting discounts, commissions, and other offering expenses). Current cash runway supports continued advancement of danicamtiv, ataciguat, and tonlamarsen through clinical data readouts and the initiation of Phase 3 clinical trials across all three programs. Second Quarter Financial Results • Cash Position: Cash, cash equivalents and investments were $660.7 million as of June 30, 2026, compared to $335.5 million as of December 31, 2025. The increase reflects net proceeds from the Company’s initial public offering in June 2026, offset by cash used in operations. • R&D Expenses: Research and development expenses were $56.4 million for the quarter ended June 30, 2026, compared to $35.8 million for the comparable prior-year period. The increase was primarily driven by clinical trial expenses across all three development programs and increased headcount to support the advancing clinical pipeline. • G&A Expenses: General and administrative expenses were $18.9 million for the quarter ended June 30, 2026, compared to $21.3 million for the comparable prior-year period. The decrease was primarily driven by a one-time integration bonus recognized in the prior year, partially offset by higher personnel-related costs and other corporate expenses. • Net Loss: Net loss was $116.2 million for the quarter ended June 30, 2026, compared to $57.4 million for the comparable prior year period. The net loss increased primarily as a result of higher R&D expenses as described above.
