Executive Summary

Synlogic filed Amendment No. 1 to its 2025 Form 10-K solely to include Part III items (director/officer info, executive compensation, beneficial ownership, related-party transactions, and audit fees) that were omitted from the original filing. The company has one employee, is quoted on the OTC Marketplace, and is evaluating strategic alternatives including a potential merger or sale. No financial statements were amended or restated.

Key Facts

  • Amendment adds Part III items (directors, executive compensation, ownership, related-party transactions, audit fees) that were omitted from the original 10-K.
  • No financial statements were amended or restated; no error corrections were made.
  • Company has one full-time employee as of March 31, 2026, focused on strategic transaction assessment.
  • Stock is quoted on the OTC Marketplace after delisting from Nasdaq.
  • Funicular Funds (28.35%), NEA 14 (25.02%), and Baselake Partners (9.76%) are the largest stockholders.
  • Audit fees paid to KPMG were $365,000 in 2025, down from $570,010 in 2024.
  • CEO/CFO Mary Beth Dooley received total compensation of $335,500 in 2025 (salary $325,000 + 401k match $10,500), down from $486,490 in 2024.

Financial Impact

No financial impact — this is a purely administrative amendment adding governance disclosures. Audit fees declined from $570,010 to $365,000 year-over-year.

Risk Factors

  • Company has only one employee and no active pipeline after discontinuing lead candidate SYNB1934.
  • Stock trades on OTC with limited liquidity; strategic alternatives may result in merger, sale, or dissolution.
  • Concentrated ownership: two entities (Funicular Funds and NEA 14) control over 53% of shares.
