MAIA Biotechnology March 2026 Update Note

Highlights from the note include:

FY 2025 Financial Results and Strengthened Liquidity Position - MAIA Biotechnology reported financial results for the year ended December 31, 2025, reflecting continued investment in clinical development alongside a corresponding increase in operating losses. Research and development expenses increased to $14.55 million from $10.01 million in the prior year, driven by ongoing pipeline advancement, while general and administrative expenses rose to $9.72 million from $6.95 million. As a result, loss from operations widened to $24.27 million from $16.96 million in 2024. Despite higher operating losses, net loss narrowed to $22.40 million from $23.25 million in the prior year, primarily due to favorable non-operating items. Operating cash burn totalled $18.84 million compared to $15.70 million in 2024, while year-end cash reserves stood at $8.66 million. To strengthen its balance sheet and support ongoing clinical programs, the company completed a public offering in March 2026, issuing 20.0 million shares at $1.50 per share for aggregate gross proceeds of $30 million. This capital raise materially enhances near-term funding visibility and is expected to support continued execution of its clinical strategy, including advancement of the ongoing Phase 3 study for ateganosine (THIO) and upcoming data readouts. Based on the strengthened post-financing liquidity position, we believe the company is adequately funded to advance key clinical near-term milestones, although additional capital raises may be undertaken as the development program progresses.
$30 Million Equity Raise Completed Through Underwritten Public Offering Led by Healthcare Investors to Fund Clinical Development and Strengthen Balance Sheet - MAIA Biotechnology completed a $30 million underwritten public offering of 20,000,000 shares of common stock at $1.50 per share, generating gross proceeds of approximately $30 million prior to underwriting discounts and expenses. The company also granted underwriters a 45-day option to purchase up to an additional 3,000,000 shares to cover over-allotments. Notably, the financing was structured as a straightforward common stock offering with no warrant coverage and included participation from healthcare-dedicated investors alongside existing shareholders. Net proceeds are intended to support ongoing and planned clinical trials, including the pivotal THIO-104 Phase 3 study, as well as working capital and general corporate purposes. From our perspective, the successful completion of this sizeable, warrant-free financing led by sector-focused investors materially strengthens MAIA's capital position as it advances through late-stage clinical execution and upcoming value-defining milestones.
Valuation - Building on the strengthened balance sheet and improved funding visibility, we have revisited our underlying assumptions for THIO in NSCLC. We increase our probability of success (PoS) from 25% to 35%, reflecting the program's advancement into a pivotal Phase 3 trial, supportive efficacy signals observed in earlier studies, and regulatory momentum, including Fast Track designation. In our view, the transition into a registrational study represents the achievement of a key clinical milestone and enhances visibility into the development pathway. Incorporating these updates, we have refined our financial model to reflect the latest reported financial results, and the impact of the recent equity raise, including associated dilution. We have also shifted our expected commercialization timeline from 2027 to 2028, aligning with the anticipated duration of the Phase 3 trial and the regulatory review process. While dilution from the capital raise weighs on per-share value, this is partially offset by improved funding visibility, reduced near-term financing risk, and an increased probability of clinical success. Our discount rate remains unchanged at 13.60%. Based on these revised assumptions, alongside our updated comparable company analysis, we derive an illustrative valuation of $10.27 per share, contingent on successful execution by the company.
