FULL YEAR 2023 FINANCIAL RESULTS

Revenue: Total revenue for the year ended December 31, 2023 was $20.8 million, compared to $31.1 million for the year ended December 31, 2022. The decrease in revenue was primarily due to the collaboration agreement with Calico ending in January 2023 and completion of research activities for a target under the collaboration agreement with Biogen, partially offset by the completion of research activities for select targets under the collaboration agreement with Roche. 2023 revenue reflects amounts recognized under our collaboration agreements with Biogen, Calico, and Roche.

Research and Development (R&D) Expense: R&D expense for the year ended December 31, 2023 was $117.7 million, compared to $117.8 million for the year ended December 31, 2022. R&D expense was relatively flat year over year as preclinical costs decreased and clinical costs increased with the transition of CFT1946 to clinical development.

General and Administrative (G&A) Expense: G&A expense for the year ended December 31, 2023 was $42.1 million, compared to $42.8 million for the year ended December 31, 2022. The decrease in G&A expense was primarily attributable to a decrease in professional fees.

Net Loss and Net Loss per Share: Net loss for the year ended December 31, 2023 was $132.5 million, compared to $128.2 million for the year ended December 31, 2022. Net loss per share for the year ended December 31, 2023 was $2.67, compared to $2.62 for the year ended December 31, 2022.

Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of December 31, 2023 were $281.7 million, compared to $337.1 million as of December 31, 2022. Cash and cash equivalents as of December 31, 2023 do not include $25 million in proceeds from the sale of shares of our common stock to a subsidiary of Betta Pharmaceuticals, $14.1 million of proceeds in connection with the settlement of 2,500,601 shares under our ATM program, and the $10.0 million upfront payment related to our collaboration agreement with Merck, all of which were received in January 2024. The company expects that its cash, cash equivalents and marketable securities as of December 31, 2023, together with these amounts received in January 2024, which result in a proforma balance of approximately $330 million, will enable the company to fund its operating plan into 2027.
