Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased by $0.541 million (37%) year-over-year, driven primarily by a $0.449 million increase in licensing revenue from higher royalties under agreements with Eli Lilly and Sun Pharma.
• Expense Increases: Total costs and expenses rose by $4.649 million. Research and development (R&D) expenses increased by $4.073 million, largely due to higher clinical development costs for ATI-052 and manufacturing costs for ATI-9494.
• Net Loss Expansion: Net loss widened by $4.739 million to $19.824 million, reflecting increased operational spending outpacing revenue growth.
• Capital Raise: In March 2026, the company sold 18.4 million shares under its at-the-market (ATM) facility, generating net proceeds of approximately $57.9 million.
• Investment Activity: Net cash used in investing activities was $30.9 million, primarily due to significant purchases of marketable securities ($51.7 million) offset by proceeds from maturities ($20.8 million).

Outlook, Risks, and Management Commentary

• Liquidity: As of March 31, 2026, the company held $190.8 million in cash, cash equivalents, and marketable securities. Management believes this is sufficient to fund operations for more than 12 months. However, the company expects to incur significant losses in the foreseeable future and will require additional capital.
• Clinical Pipeline Updates:
  • Bosakitug (ATI-045): Phase 2 trial in atopic dermatitis initiated in June 2025; top-line data expected in Q4 2026.
  • ATI-2138: Positive Phase 2a results announced in July 2025. A Phase 2b basket study for lichen planus is planned for initiation in H2 2026.
  • ATI-052: Positive Phase 1a results announced in April 2026. Phase 1b trials in atopic dermatitis and asthma initiated in early 2026, with data expected in H2 2026.
  • ATI-9494: IND application expected in H2 2026.
• Risks: The company faces risks related to the uncertainty of clinical trial outcomes, the ability to raise additional capital on acceptable terms, and potential impacts from macroeconomic conditions (inflation, geopolitical tensions). There is no assurance that profitable operations will ever be achieved.
• Contingent Consideration: A liability of $11.0 million remains related to the acquisition of Confluence Life Sciences, based on future regulatory and commercial milestones.

Key Facts for Investor Verification

• Cash Runway: Verify the sufficiency of the $190.8 million liquidity position against the projected burn rate of approximately $18 million per quarter in operating cash outflows.
• Dilution Risk: Note the recent issuance of 18.4 million shares via the ATM facility and the existence of 14.3 million warrants issued to Biosion/CTTQ (3 million unexercised as of Q1 2026).
• Revenue Quality: Confirm the sustainability of licensing revenue, as a significant portion (e.g., from the Lilly agreement) is payable to third parties, reducing net economic benefit.
• Clinical Milestones: Monitor the upcoming data readouts for Bosakitug (Q4 2026) and ATI-052 (H2 2026) as critical value drivers.
• Contingent Liabilities: Track the $11.0 million contingent consideration liability and potential future milestone payments under the Biosion agreement (up to $125 million regulatory + $795 million sales milestones).
