Seres Therapeutics Announces Receipt of Expected $50 Million Installment Payment Related to VOWST Sale

CAMBRIDGE, Mass., Jan. 16, 2025 (GLOBE NEWSWIRE) -- Seres Therapeutics, Inc. (Nasdaq: MCRB) (Seres or the Company), a leading live biotherapeutics company, announced today the receipt of a $50 million installment payment related to the Company’s previously announced sale of its VOWST business to Société des Produits Nestlé S.A (SPN, and with certain of its affiliates, collectively, Nestlé Health Science). This installment payment was expected as Seres is fulfilling its transition obligations.

As previously announced, based on the Company’s existing cash, inclusive of this payment, a projected installment payment from Nestlé Health Science in July 2025 of $25 million (less up to approximately $1.5M in employment-related payments to Nestlé Health Science), transaction-related obligations and current operating plans, the Company expects to fund operations into the first quarter of 2026.

About Seres Therapeutics 

Seres Therapeutics, Inc. (Nasdaq: MCRB) is a clinical-stage company focused on improving patient outcomes in medically vulnerable populations through novel live biotherapeutics. Seres led the successful development and approval of VOWST™, the first FDA-approved orally administered microbiome therapeutic, which was sold to Nestlé Health Science in September 2024. The Company is developing SER-155, which has received both Breakthrough Therapy and Fast Track designation, and which has demonstrated a significant reduction in bloodstream infections and related complications (as compared to placebo) in a Phase 1b clinical study in patients undergoing allo-HSCT. SER-155 and the Company's other pipeline programs are designed to target multiple disease-relevant pathways and are manufactured from standard clonal cell banks via cultivation, rather than from the donor-sourced production process used for VOWST. In addition to allo-HSCT, the Company intends to evaluate SER-155 and other cultivated live biotherapeutic candidates in other medically vulnerable patient populations including autologous-HSCT patients, cancer patients with neutropenia, CAR-T recipients, individuals with chronic liver disease, solid organ transplant recipients, as well as patients in the intensive care unit and long-term acute care facilities.
