Management's Discussion and Analysis (MD&A) Highlights

Management discussed the company's financial condition and operating results for the fiscal year ended December 31, 2025. This discussion highlighted significant progress in lorundrostat's development and continued investment in its pipeline.

The company's primary operational achievement for fiscal year 2025 was the submission of a New Drug Application (NDA) for lorundrostat to the U.S. Food and Drug Administration (FDA) in December 2025. This pivotal step, based on positive results from its Phase 3 clinical program, marks a critical transition from development to potential commercialization. The FDA accepted the NDA for review, setting an anticipated Prescription Drug User Fee Act (PDUFA) target action date in September 2026. This date represents when the FDA expects to complete its review. This milestone signifies the culmination of extensive clinical trials and positions the company for potential market entry.

Financially, as a pre-revenue biopharmaceutical company, Mineralys Therapeutics continued to experience substantial losses. The net loss increased to approximately $(150.5) million in FY2025 from $(120.3) million in FY2024. This increase primarily stemmed from higher Research & Development (R&D) expenses, which rose to $105.2 million from $85.1 million. These expenses reflect late-stage clinical activities, regulatory submission costs, and pre-commercial manufacturing efforts. General & Administrative (G&A) expenses also increased to $45.3 million from $35.2 million, due to increased personnel, legal, and professional fees associated with public company operations and pre-commercialization planning.

Management identified several key challenges:

1. Regulatory Approval: The company's immediate future hinges entirely on the FDA's decision regarding lorundrostat by the September 2026 PDUFA date. Any delays, requests for additional data, or outright rejection would severely impact the company's valuation and prospects.
2. Cash Burn and Funding Needs: Mineralys continues to operate at a significant cash burn rate, estimated at approximately $12-15 million per month. This necessitates substantial additional funding in the near future to support potential commercialization, ongoing R&D, and general operations.
3. Single Product Dependency: The company's entire valuation and future success are currently tied to lorundrostat. No other pipeline candidates are in advanced stages to diversify risk.
4. Market Competition: The hypertension market is highly competitive, with numerous established generic and branded therapies. Lorundrostat will need to demonstrate clear differentiation and clinical superiority to gain market share.

Financial Health and Liquidity

As of December 31, 2025, Mineralys Therapeutics reported cash and cash equivalents of approximately $200 million. Based on its current operating expenses and projected cash burn, the company estimates this cash balance provides a runway of approximately 16 months.

The company explicitly states it "will need substantial additional funds" to continue operations beyond early 2027, particularly to fund lorundrostat's commercial launch if approved. Potential financing options include further equity offerings, which would dilute existing shareholders, or debt financing, which would add leverage to the balance sheet. The company currently carries minimal debt.

Risk Factors

Investors should be aware of several significant risks:

• Regulatory Risk: The FDA may not approve lorundrostat, or it may require additional clinical trials, significantly delaying or preventing market entry. The PDUFA date in September 2026 is a critical binary event.
• Commercialization Risk: Even if approved, lorundrostat may not achieve commercial success due to market competition, pricing pressures, limited reimbursement, or slower-than-anticipated physician adoption.
• Funding Risk & Dilution: The company will require significant capital raises in the next 12-18 months. Future equity financings could lead to substantial dilution for current shareholders (e.g., 20-30% or more), impacting per-share value.
• Clinical & Safety Risk: Despite positive Phase 3 data, unforeseen safety issues or side effects could emerge during post-marketing surveillance or in broader patient populations, leading to label restrictions or withdrawal.
• Single Asset Concentration: The company's value depends almost entirely on lorundrostat. Failure of this single asset would have catastrophic consequences.
• Competition: The hypertension market is crowded. Lorundrostat faces competition from established generic drugs (e.g., diuretics, ACE inhibitors, ARBs, beta-blockers, calcium channel blockers) and other pipeline drugs targeting resistant hypertension (e.g., from companies like AstraZeneca, which acquired CinCor Pharma).
• Reliance on Third Parties: Mineralys relies heavily on contract research organizations (CROs) for clinical trial execution and contract manufacturing organizations (CMOs) for drug production. Any failure or delay by these third parties could impact timelines and costs.
• Intellectual Property: Protecting lorundrostat through patents is crucial. Any challenges to patent validity or infringement could undermine market exclusivity.
• Reliance on License Agreement: The company's rights to lorundrostat stem from a license agreement with Tanabe Pharma Corporation. Termination or breach of this agreement could result in loss of rights to the drug.
• Stock Volatility: As a development-stage biotech company, the stock price is highly sensitive to clinical trial results, regulatory updates, and financing news, leading to significant volatility.

Future Outlook and Strategy

The FDA's review of lorundrostat dominates Mineralys Therapeutics' immediate future, with the PDUFA date in September 2026 serving as the next major catalyst. If approved, the company plans to initiate commercialization efforts, which will require significant investment in sales, marketing, and market access infrastructure. The company's strategy remains focused on securing FDA approval for lorundrostat and preparing for its commercial launch.

Beyond approval, the company anticipates needing to raise additional capital to fund its commercial operations and potentially explore further development of lorundrostat in other indications or expand its pipeline. The company reported no significant changes in executive leadership or core corporate strategy during fiscal year 2025.

Market Trends & Regulatory Environment:

• Regulatory Pathway: The successful NDA submission and ongoing FDA review are the primary regulatory drivers. The outcome will dictate the company's trajectory.
• Hypertension Market Dynamics: The growing global prevalence of hypertension, particularly resistant hypertension, presents a substantial market opportunity. However, market access and reimbursement policies will be critical for commercial success.
• Economic Factors: Broader macroeconomic conditions, such as interest rates and inflation, could influence the cost and availability of future capital, impacting the company's ability to fund its operations and commercial launch.

Competitive Position

Lorundrostat aims to address a significant unmet need in resistant hypertension, a condition affecting millions of patients whose blood pressure remains uncontrolled despite multiple medications. Its mechanism as an aldosterone synthase inhibitor offers a novel approach compared to many existing therapies. Experts estimate the global market for resistant hypertension to be several billion dollars annually. The company believes lorundrostat's differentiated mechanism and clinical profile could position it as an important new treatment option, but it will need to compete effectively against standard-of-care treatments and other emerging therapies.
