• Substantial Doubt About Going Concern

  Management has concluded that substantial doubt exists about the company's ability to continue as a going concern for at least 12 months from the financial statement issuance date (March 12, 2026), citing the need for additional funding beyond Q3 2026.

• Lead Clinical Program Paused Due to Funding

  The company has paused additional investment in the Phase 2 study for SER-155, its most advanced live biotherapeutic candidate, while continuing to seek funding. SER-155 previously received FDA Fast Track and Breakthrough Therapy designations.

• Significant Workforce Reductions

  Seres Therapeutics implemented a 25% workforce reduction in September 2025, followed by an additional 30% reduction in February 2026, as part of cost-reduction measures to extend its cash runway.

• Financial Performance Driven by Asset Sale and Cost Cuts

  For the year ended December 31, 2025, the company reported net income from continuing operations of $5.7 million and positive cash provided by operating activities of $1.1 million, a significant improvement from a net loss of $125.8 million and negative cash flow of $148.6 million in 2024. This turnaround is largely due to $75 million in installment payments from the VOWST business sale and reduced operating expenses.

Seres Therapeutics has disclosed substantial doubt about its ability to continue as a going concern, indicating a critical financial situation. This is further exacerbated by the decision to pause additional investment in the Phase 2 study for SER-155, its most advanced live biotherapeutic candidate with Breakthrough Therapy designation, due to ongoing funding challenges. While the company reported a net income from continuing operations and positive cash flow from operations for 2025, these improvements are largely attributed to proceeds from the sale of its VOWST business and aggressive cost-reduction measures, including two significant workforce reductions. The pausing of a key clinical program and the explicit going concern warning signal severe operational and financial distress, raising significant concerns about the company's long-term viability and ability to advance its pipeline without substantial new capital or partnerships.
