Recent Business Highlights

Announced details for an oral presentation on May 30 at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting featuring pivotal data from the Phase 3 PEAK trial in patients with Gastrointestinal Stromal Tumors (GIST) who have received prior treatment with imatinib
Presented updated preclinical data from the company's KRAS and ErbB2 candidates at the American Association of Cancer Research (AACR) annual meeting
Announced submission of the company's New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for bezuclastinib in patients with GIST who have received prior treatment with imatinib. Based on the positive results from the PEAK trial, the bezuclastinib NDA was submitted under the FDA's Real-Time Oncology Review (RTOR) program, which is intended to enable a more streamlined review process. Bezuclastinib was also granted Breakthrough Therapy Designation as a treatment for GIST earlier in 2026.
Announced the FDA accepted its NDA for bezuclastinib in patients with NonAdvanced Systemic Mastocytosis (NonAdvSM) and assigned a Prescription Drug User Fee Act (PDUFA) target action date of December 30, 2026
Presented six posters with bezuclastinib in patients with NonAdvSM at the 2026 AAAAI annual meeting
Initiated Phase 1 studies for both CGT4255, a novel, selective, brain-penetrant ErbB2 inhibitor and CGT6297, a novel, selective and potential best-in-class PI3Kα inhibitor

First Quarter 2026 Financial Results

Cash and Cash Equivalents: As of March 31, 2026, cash, cash equivalents and marketable securities were $866.4 million, which includes net proceeds of $45.7 million from shares recently sold under the Company's at-the-market (ATM) stock offering as well as non-recurring payments totaling $18.0 million related to annual performance-based bonus compensation and a milestone payment to Plexxikon. Based on our current plans, we expect our existing cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements into 2028, including the commercialization of bezuclastinib in SM and GIST.

R&D Expenses: Research and development expenses were $75.4 million for the first quarter of 2026 compared to $63.0 million for the first quarter of 2025. The increase was driven by increased early-stage, preclinical and discovery programs as we advance our pipeline of programs into Phase 1 clinical trials and IND-enabling studies, and includes one-time costs associated with the wind down of the FGFR clinical program. R&D expenses include non-cash stock compensation expense of $8.9 million for the first quarter of 2026 as compared to $5.3 million for the first quarter of 2025.

G&A Expenses: General and administrative expenses were $28.2 million for the first quarter of 2026 compared to $11.9 million for the first quarter of 2025. The increase was primarily due to the growth of the organization and activities related to the anticipated commercial launch of bezuclastinib. G&A expenses include non-cash stock compensation expense of $8.0 million for the first quarter of 2026 as compared to $4.8 million for the first quarter of 2025.

Net Loss: Net loss was $97.4 million for the first quarter of 2026 compared to a net loss of $72.0 million for the first quarter of 2025.

Inducement Grants Under Nasdaq Listing Rule 5635(c)(4)

Cogent also announced today that, on April 29, 2026, the Compensation Committee of Cogent's Board of Directors, made up entirely of independent directors, approved the grants of "inducement" equity awards to seven new employees under the company's 2020 Inducement Plan with a grant date of April 29, 2026.

The employees received, in the aggregate, (i) nonqualified options to purchase 62,600 shares of Cogent common stock and (ii) 48,600 restricted stock units (RSUs). Each option has a 10-year term, an exercise price equal to the closing price of Cogent's common stock on the grant date, and a 4-year vesting schedule with 25% vesting on the 1-year anniversary of the grant date and the remainder vesting in equal monthly installments over the subsequent 36 months, provided such employee remains employed through each such vesting date. The RSUs vest annually in equal installments over 4 years from the grant date, provided such employee remains employed through each such vesting date.

About Cogent Biosciences, Inc.

Cogent Biosciences is a biotechnology company focused on developing precision therapies for genetically defined diseases. The most advanced clinical program, bezuclastinib, is a selective tyrosine kinase inhibitor that is designed to potently inhibit the KIT D816V mutation as well as other mutations in KIT exon 17. KIT D816V is responsible for driving Systemic Mastocytosis, a serious disease caused by unchecked proliferation of mast cells. Exon 17 mutations are also found in patients with advanced Gastrointestinal Stromal Tumors (GIST), a type of cancer with strong dependence on oncogenic KIT signaling. In addition, the Cogent Research Team is developing a portfolio of novel targeted therapies to help patients fighting serious, genetically driven diseases targeting mutations in ErbB2, PI3Kα, KRAS and JAK2. Cogent Biosciences is based in Waltham, MA and Boulder, CO. Visit our website for more information at www.cogentbio.com.
