•Anaptys is seeking reversion of Jemperli rights as a remedy; the Company anticipates a judgement in Q4 2026 or Q1 2027
Second Quarter Financial Results
•The separation of AnaptysBio and First Tracks Biotherapeutics was completed on April 20, 2026. Beginning in the second quarter of 2026, AnaptysBio reclassified historical First Tracks Biotherapeutics, Inc. related assets, liabilities and expenses as discontinued operations.
•On May 18, 2026, Anaptys changed its fiscal year-end from December 31 to June 30. The Company will begin to file quarterly reports based on the new fiscal year beginning with the quarter ending September 30, 2026.
•As of June 30, 2026, Anaptys has not repurchased any shares under its $100 million Stock Repurchase Plan, which will expire on December 31, 2026, may be suspended or discontinued at any time, and does not obligate the company to acquire any amount of common stock.
•Cash, cash equivalents and investments totaled $164.1 million as of June 30, 2026, compared to $211.6 million as of December 31, 2025, for a decrease of $47.5 million due primarily to $72.9 million for operating activities offset by $25.4 million received from stock option exercises.
•Collaboration revenue was $27.5 million and $53.0 million for the three and six months ended June 30, 2026, compared to $22.3 million and $50.0 million for the three and six months ended June 30, 2025. The increase is primarily due to Jemperli royalties increasing 25% and 34% for the three and six months ended June 30, 2026, offset by $9.7 million in revenue recognized for the Vanda license agreement for the three month and six months ended June 30, 2025.
•General and administrative expenses were $16.0 million and $23.4 million for the three and six months ended June 30, 2026, compared to $4.0 million and $8.3 million for the three and six months ended June 30, 2025. The
increase was due primarily to legal costs for the separation of the company and the GSK and Tesaro lawsuit and non-cash stock compensation.
•Research and development expenses from continuing operations were a negative $2.7 million for the six months ended June 30, 2026, compared to a negative $1.7 million six months ended June 30, 2025. The negative balance for the six months ended June 30, 2026, was primarily due adjustments related to the closeout of clinical contracts reducing expenses incurred prior to the separation.
•Benefit for income taxes for continuing operations was $181.5 million for the six months ended June 30, 2026. The benefit recognized was primarily due to the release of the valuation allowance on deferred tax assets due to the anticipated usage of deferred tax assets in the future due to the separation from First Tracks Biotherapeutics.
•Net income from continuing operations was $177.3 million and $176.4 million for the three and six months ended June 30, 2026, or a basic net income per share of $6.06 and $6.09, compared to a net income from continuing operations of $5.7 million and $16.6 million for the three and six months ended June 30, 2025, or a basic net income per share of $0.20 and $0.56.
