SOMERVILLE, Mass., May 7, 2026 — Generate Biomedicines, Inc. (NASDAQ: GENB) (“Generate”) today reported financial results for the first quarter ended March 31, 2026, and highlighted progress across its clinical portfolio.

“We saw strong progress in the first quarter across our clinical pipeline, next generation of therapeutic programs, and advancing our platform,” said Mike Nally, chief executive officer of Generate Biomedicines, Inc. “We are advancing GB-0895 in Phase 3 for severe asthma and Phase 1b for COPD. In oncology, we expect to progress two clinical trials this year with GB-4362, an MMAE neutralizer, and GB-5267, a MUC16 CAR T developed with Roswell Park. Together, these programs reflect the breadth of our clinical portfolio across therapeutic areas, modalities, and both wholly owned and partnered programs.”

Recent Progress

Generate continues to advance its generative biology platform, applying its capabilities across therapeutic areas and modalities to advance programs into the clinic.

In inflammation and immunology, Generate's GB-0895 (anti-TSLP) program continues to advance, with Phase 3 clinical trials underway in severe asthma with its global SOLAIRIA-1 and SOLAIRIA-2 replicate studies, and a Phase 1b trial is ongoing in COPD.

In oncology, Generate's GB-4362 (MMAE neutralizer) program has activated clinical trial sites, and the first patient is expected to be dosed in mid-2026. This program has received FDA Fast Track designation.

Generate's GB-5267 (MUC16 armored CAR T) program, developed in collaboration with Roswell Park Comprehensive Cancer Center, is expected to dose the first patient in the second half of 2026 in a Phase 1 clinical trial in solid tumors, initially targeting ovarian cancer.

Financial Results

Cash, cash equivalents, and marketable securities were $516.6 million as of March 31, 2026, compared with $221.5 million as of December 31, 2025. The cash, cash equivalents, and marketable securities as of March 31, 2026 reflects $369.3 million in

net proceeds from Generate's IPO, which was completed on March 2, 2026. Generate believes its existing cash, cash equivalents, and marketable securities will be sufficient to fund its operations into the first half of 2028. Generate expects to require additional capital to support long-term operations.

Revenue for the quarter ended March 31, 2026, was $7.2 million, compared with $8.8 million for the same period in 2025. This revenue reflects developments in the ongoing Amgen and Novartis research programs.

Research and development expenses were $57.8 million for the quarter, compared with $46.8 million for the same period in 2025. The increase was primarily driven by continued investment in the GB-0895 Phase 3 program in severe asthma, as well as by an increase in personnel-related costs, offset by a decrease in external discovery and other program related costs.

General and administrative expenses were $13.5 million for the quarter, compared with $10.1 million for the same period in 2025. The increase was primarily driven by an increase in stock-based compensation and professional fees associated with operating as a public company following Generate’s initial public offering in February 2026.

Net loss was $61.7 million for the quarter ended March 31, 2026, compared with $44.3 million for the same period in 2025, which includes non-cash stock-based compensation expense of $6.4 million and $4.7 million, respectively.

Net cash used in operating activities was $80.4 million for the quarter ended March 31, 2026, compared with $53.2 million for the same period in 2025.
