SECOND QUARTER 2023 FINANCIAL RESULTS

Revenue: Total revenue for the second quarter of 2023 was $2.7 million, compared to $13.8 million for the second quarter of 2022. The decrease in revenue was due to a reduction of revenue recognized for research activities under the Biogen and Calico collaborations. Total revenue for the second quarter of 2023 reflects revenue recognized under collaboration agreements with Roche and Biogen, and total revenue recognized in the second quarter of 2022 reflects revenue recognized under collaborations agreements with Roche, Biogen, and Calico.

Research and Development (R&D) Expense: R&D expense for the second quarter of 2023 was $29.9 million, compared to $31.3 million for the second quarter of 2022. The reduction in R&D expense was primarily attributable to a decrease in IND-enabling activities as programs transition to the clinic.

General and Administrative (G&A) Expense: G&A expense for the second quarter of 2023 was $10.3 million, compared to $9.9 million for the second quarter of 2022. The higher G&A expense was attributable to a slight increase in professional fees.

Net Loss and Net Loss per Share: Net loss for the second quarter of 2023 was $35.9 million, compared to $27.4 million for the second quarter of 2022. Net loss per share for the second quarter of 2023 was $0.73 compared to $0.56 for the second quarter of 2022.

Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of June 30, 2023, were $286.7 million, compared to $337.1 million as of December 31, 2022. The decrease in cash was primarily driven by expenditures to fund operations, partially offset by the $10.0 million upfront payment received from Betta Pharmaceuticals. C4T expects that its cash, cash equivalents and marketable securities as of June 30, 2023, along with the anticipated equity investment from an affiliate of Betta Pharmaceuticals, will be sufficient to fund planned operating expenses and capital expenditures into the second half of 2025.

About CFT7455

CFT7455 is an orally bioavailable MonoDAC™ degrader designed to be highly potent and selective against its intended targets of Ikaros (IKZF1) and Aiolos (IKZF3). CFT7455 binds with high affinity to the E3 ligase adapter protein, cereblon, to target and degrade IKZF1/3 for the treatment of multiple myeloma and non-Hodgkin's lymphomas, including peripheral T cell lymphoma and mantle cell lymphoma. In early clinical data, CFT7455 demonstrated deep and durable degradation of IKZF1/3. C4T is enrolling patients in its ongoing Phase 1/2 clinical trial of CFT7455. More information about this trial may be accessed at www.clinicaltrials.gov (identifier: NCT04756726).

About CFT8634

CFT8634 is an orally bioavailable BiDAC™ degrader designed to be potent and selective against BRD9. BRD9 was previously considered an undruggable target due to the inability of bromodomain inhibitors to effectively treat cancers dependent on BRD9. Unlike BRD9 inhibition, BRD9 degradation has been shown to be efficacious in pre-clinical models of synovial sarcoma. C4T is enrolling patients in its ongoing Phase 1/2 clinical trial of CFT8634 for the treatment of synovial sarcoma and SMARCB1-null solid tumors. More information about this trial may be accessed at www.clinicaltrials.gov (identifier: NCT05355753).
