First Quarter Financial Results

• The separation of Anaptys and First Tracks Bio was completed on April 20, 2026. As a result, in the first quarter of 2026, the financial results include assets, liabilities and expenses related to both companies. Beginning in the second quarter of 2026, Anaptys expects to reclassify historical First Tracks Bio related assets, liabilities and expenses as discontinued operations.
• Cash, cash equivalents and investments totaled $286.5 million as of March 31, 2026, compared to $311.6 million as of Dec. 31, 2025, for a decrease of $25.1 million due primarily to operating activities offset by $14.0 million received from stock option exercises.
• Collaboration revenue was $25.6 million for the three months ended March 31, 2026, compared to $27.8 million for the three months ended March 31, 2025. The decrease in revenue was primarily due to $9.7 million in revenue recognized for the Vanda license agreement for the three months ended March 31, 2025 offset by Jemperli royalties increasing 44% from $17.2 million to $24.7 million for the three months ended March 31, 2026.
• Research and development expenses were $34.0 million for the three ended March 31, 2026, compared to $41.2 million for the three months ended March 31, 2025. The decrease for the three months ended March 31, 2026 was primarily due to decreased development costs for rosnilimab and ANB032 offset by increased costs relating to the phase 1 trials for ANB033. The R&D non-cash, stock-based compensation expense was $4.6 million for the three months ended March 31, 2026 as compared to $4.4 million in the same period in 2025.
• General and administrative expenses were $26.2 million for the three months ended March 31, 2026, compared to $14.1 million for the three months ended March 31, 2025. The increase was due primarily to legal costs for the separation of the company, ongoing GSK litigation and non-cash stock compensation costs incurred for our former Chief Financial Officer and former Chief Legal Officer. The G&A non-cash, stock-based compensation expense was $9.7 million for the three months ended March 31, 2026 as compared to $4.8 million in the same period in 2025.
• Net loss was $52.9 million for the three months ended March 31, 2026, or a net loss per share of $1.84, compared to a net loss of $39.3 million for the three months ended March 31, 2025, or a net loss per share of $1.28.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, including, but not limited to whether Anaptys is able to protect its financial collaborations; and its ability to return value to its shareholders. Statements including words such as “plan,” “continue,” “expect,” or “ongoing” and statements in the future tense are forward-looking statements. These forward-looking statements involve risks and uncertainties, as well as assumptions, which, if they do not fully materialize or prove incorrect, could cause its results to differ materially from those expressed or implied by such forward-looking statements. Forward-looking statements are subject to risks and uncertainties that may cause the company’s actual activities or results to differ significantly from those expressed in any forward-looking statement, including risks and uncertainties related to the company’s ability to protect its financial collaborations and return value to its shareholders, the company’s ability to operate efficiently with a limited staff, and other risks and uncertainties described under the heading “Risk Factors” in documents the company files from time to time with the Securities and Exchange Commission. These forward-looking statements speak only as of the date of this press release, and the company undertakes no obligation to revise or update any forward-looking statements to reflect events or circumstances after the date hereof.

This press release also includes a reference to EBIT margin which is a measure not presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”), which Anaptys believes provides important perspective with respect to operational profitability. Non-GAAP financial measures may exclude items that are significant in understanding and assessing Anaptys’ financial results, should not be considered in isolation or as an alternative to GAAP measures, and should be considered only as a supplement to, and not as superior to, GAAP measures. Anaptys cannot predict with certainty the magnitude or scope of certain items that would be included in the most directly comparable GAAP measure to EBIT margin for the relevant future periods, and such items may be significant. Due to these uncertainties, Anaptys cannot provide a quantitative reconciliation of EBIT margin to the most directly comparable GAAP financial measure without unreasonable effort.
