• Pemvidutide Shows Strong Clinical Efficacy

  The lead product candidate, pemvidutide, demonstrated positive 24-week and 48-week topline results in the IMPACT Phase 2b trial for MASH, achieving statistically significant MASH resolution and anti-fibrotic activity. It also received FDA Breakthrough Therapy and Fast Track designations for MASH, with a pivotal Phase 3 trial planned for 2026. Additionally, the RECLAIM Phase 2 trial for AUD completed enrollment ahead of schedule, and the RESTORE Phase 2 trial for ALD was initiated.

• Significant Capital Raises Bolster Liquidity

  Altimmune raised approximately $173.3 million in net proceeds from at-the-market (ATM) offerings during 2025. Subsequent to the fiscal year end, in January and February 2026, the company secured an additional $70.4 million in net proceeds from a registered direct offering (12,397,920 shares and 4,647,534 pre-funded warrants) and $8.2 million from further ATM sales, providing a total of $78.6 million in new capital. This significantly extends the company's cash runway, with $273.5 million in cash, cash equivalents, restricted cash, and short-term investments as of December 31, 2025, projected to fund operations for at least 12 months from the filing date.

• Legal Overhangs Resolved

  A class action lawsuit and a shareholder derivative complaint, both filed in 2025 and related to alleged misleading statements regarding pemvidutide, were voluntarily dismissed without prejudice in November and December 2025, respectively. This removes potential legal distractions and liabilities.

• Increased Share Count and Potential Dilution

  As of February 27, 2026, the number of common shares outstanding increased to 130,069,983, up from 110,882,735 at December 31, 2025, primarily due to the recent offerings. The company is authorized to issue up to 200,000,000 shares of common stock. If all authorized shares were issued, dilution would be 53.76% based on current outstanding shares.

This annual report details Altimmune's strong clinical advancements for its lead product candidate, pemvidutide, across multiple indications, including MASH, AUD, and ALD. The positive Phase 2b results for MASH, coupled with FDA Breakthrough Therapy and Fast Track designations, significantly de-risk the program and outline a clear path to a pivotal Phase 3 trial in 2026. Furthermore, the company has substantially strengthened its financial position through successful at-the-market offerings in 2025 and a significant registered direct offering in early 2026, providing crucial liquidity for ongoing development. The voluntary dismissal of class action and derivative lawsuits also removes a notable legal overhang. While these capital raises are dilutive, they are essential for funding the advanced clinical programs, making this a very important update for investors.
