Business Context and Reporting Period

This report covers the quarterly period ended June 30, 2026. Acumen Pharmaceuticals is a clinical-stage biopharmaceutical company focused on developing treatments for Alzheimer's disease (AD). The company's primary asset is sabirnetug, a monoclonal antibody currently in the Phase 2 ALTITUDE-AD clinical trial, with top-line results expected in late 2026. Additionally, the company is advancing an Enhanced Brain Delivery (EBD) program (candidates ACU301 and ACU401) through a collaboration with JCR Pharmaceuticals.

Key Financial Metrics

Note: The company has no product revenue. Margins are not applicable.

Material Changes vs. Prior Period

• Reduced Net Loss: Net loss decreased by $16.3 million (23%) compared to the prior year period, primarily driven by a $18.1 million reduction in R&D expenses.
• R&D Expense Reduction: R&D spending dropped significantly due to reduced manufacturing/materials costs ($21.9M) and CRO costs ($6.7M) for the ALTITUDE-AD trial. This was partially offset by a $9.3 million expense related to the option exercise payment for the JCR EBD collaboration.
• Capital Raise: In March 2026, the company completed a private placement of 10.8 million shares, raising approximately $35.7 million in gross proceeds to fund the EBD program and working capital.
• Debt Structure: The company maintains a $30 million term loan facility with K2 HealthVentures. Short-term debt increased to $19.7 million from $8.8 million, while long-term debt decreased to $11.9 million from $22.4 million, reflecting the amortization schedule.

Outlook, Risks, and Management Commentary

• Going Concern Warning: Management has concluded that substantial doubt exists regarding the company's ability to continue as a going concern. Current cash and marketable securities ($110.2 million) are expected to fund operations only into early 2027, which is less than 12 months from the filing date.
• Clinical Milestones: The company plans to announce top-line results for the Phase 2 ALTITUDE-AD trial in late 2026. An Investigational New Drug (IND) application for the lead EBD candidate is targeted for mid-2027.
• Funding Needs: The company expects to incur substantial additional losses and will need to raise additional capital through equity offerings, debt financings, or collaborations to fund future operations and commercialization efforts.
• Risk Factors: Key risks include the failure of clinical trials, inability to secure additional funding, and the potential dilution of shareholders from future capital raises. The company also faces risks related to its reliance on third-party manufacturers and CROs.

Investor Verification Checklist

• Liquidity Runway: Verify the specific timeline for the next capital raise given the "substantial doubt" disclosure and the projection of funds lasting only into early 2027.
• ALTITUDE-AD Trial Status: Confirm enrollment numbers and any interim safety data for the Phase 2 trial, as late 2026 results are critical for valuation.
• EBD Collaboration Terms: Review the specific milestones and royalty obligations associated with the JCR Pharmaceuticals agreement, including the $555 million potential future payments.
• Debt Covenants: Examine the terms of the K2 HealthVentures term loan, specifically the conversion options and the impact of the recent private placement on the embedded derivative valuation.
• Share Count Dilution: Monitor the impact of the recent private placement (10.8M shares) and outstanding options/RSUs (approx. 20.2M potentially dilutive securities) on future share count.
