Mineralys Therapeutics Reports First Quarter 2026 Financial Results and Provides Corporate Update

– NDA for lorundrostat in adults with hypertension accepted by FDA; assigned PDUFA target date of December 22, 2026 –

– Conference call today at 4:30 p.m. ET –

RADNOR, PA – May 6, 2026 – Mineralys Therapeutics, Inc. (Nasdaq: MLYS), a biopharmaceutical company focused on developing medicines to target hypertension and related comorbidities such as chronic kidney disease (CKD), obstructive sleep apnea (OSA) and other diseases driven by dysregulated aldosterone, today announced financial results for the first quarter ended March 31, 2026, and provided a corporate update.

“We continue to make strong progress advancing lorundrostat toward potential approval, moving closer towards our goal of delivering what we believe has the potential to be a best-in-class aldosterone synthase inhibitor for patients with uncontrolled or resistant hypertension,” said Jon Congleton, Chief Executive Officer of Mineralys Therapeutics. “The FDA’s acceptance of our NDA in the first quarter marks a significant milestone for Mineralys. We continue to advance pre-commercial activities to support a successful launch of lorundrostat while maintaining strategic flexibility.”

Recent Clinical Highlights and Upcoming Milestones

•Lorundrostat New Drug Application (NDA) – The U.S. Food and Drug Administration (FDA) accepted the NDA for lorundrostat for the treatment of hypertension in combination with other antihypertensive drugs and assigned a Prescription Drug User Fee Act (PDUFA) target date of December 22, 2026. The NDA submission included the diverse dataset the Company has built with lorundrostat across five positive clinical trials that demonstrated clinically meaningful blood pressure (BP) reduction, 24-hour control and a favorable safety profile in adults with uncontrolled or resistant hypertension.

•Transform-HTN Open-Label Extension Trial – The Company’s ongoing open-label extension trial, which supported the NDA submission, enables participants to continue to receive lorundrostat and allows the Company to gather additional long-term safety and efficacy data.

•Pre-Commercial Activities Underway – The Company is executing on its pre-commercial activities in preparation for the December 22, 2026 PDUFA target date for lorundrostat. This includes engaging in market access discussions, expanded medical advocacy through communications efforts in the field to support broader education of the unmet need in uncontrolled or resistant hypertension, and sales and marketing activities preparing lorundrostat for a successful launch.

First Quarter 2026 Financial Highlights

Cash, cash equivalents and investments were $646.1 million as of March 31, 2026, compared to $656.6 million as of December 31, 2025. The Company believes that its current cash, cash equivalents and investments will be sufficient to fund its planned clinical trials and regulatory activities, as well as support corporate operations, into 2028.

Research and development (R&D) expenses for the quarter ended March 31, 2026 were $24.4 million, compared to $37.9 million for the quarter ended March 31, 2025. The decrease in R&D expenses was primarily driven by a $15.5 million reduction in preclinical and clinical costs following the conclusion of the lorundrostat pivotal program in the second quarter of 2025. This decrease was partially offset by $1.1 million of increased clinical supply, manufacturing and regulatory costs and $0.8 million of increased personnel-related expenses resulting from headcount growth and increased compensation.

General and administrative (G&A) expenses were $21.0 million for the quarter ended March 31, 2026, compared to $6.6 million for the quarter ended March 31, 2025. The increase in G&A expenses was primarily driven by $7.9 million of higher professional fees, $6.1 million of increased personnel-related expenses resulting from headcount growth and increased compensation and $0.4 million of other general and administrative expenses.

Total other income, net was $6.0 million for the quarter ended March 31, 2026, compared to $2.2 million for the quarter ended March 31, 2025. The increase reflects higher interest earned on investments in money market funds and U.S. Treasuries due to higher average cash balances invested during the quarter ended March 31, 2026.

Net loss was $39.3 million for the quarter ended March 31, 2026, compared to $42.2 million for the quarter ended March 31, 2025. The decrease was primarily attributable to the factors impacting the Company’s expenses described above.
