Price Chart
Executive Summary
Nasdaq has finalized the delisting of Synlogic, Inc. (SYBX) common stock, effective May 28, 2026, following a withdrawal of the company's appeal and a January 2026 suspension. The stock has already been trading OTC since its suspension on January 21, 2026, making this 25-NSE filing a formal deregistration step with limited incremental trading impact.
Actionable Insight
The delisting is already priced in as the stock has been suspended and trading OTC since January 21, 2026. This 25-NSE finalizes the deregistration process with the SEC. Traders should watch for any subsequent steps such as a potential voluntary deregistration under Section 12(g) or going-private transaction, which would further reduce liquidity and transparency.
