Traders should expect near-zero liquidity post-delisting and potential forced liquidation from institutional holders who cannot hold OTC stocks. If still holding, seek exit before June 18, 2026, or plan for OTC Pink Sheets trading with wide bid-ask spreads. Monitor for any going-concern or bankruptcy filings that may accompany this delisting.

Executive Summary
Nasdaq has filed a Form 25-NSE to remove IO Biotech's common stock from listing, effective June 18, 2026, following a delisting determination by Nasdaq staff on March 31, 2026, and suspension on April 7, 2026. The company did not appeal, making the delisting final. This marks the end of exchange-traded liquidity and a severe reduction in market access for the stock.
Key Facts
- Nasdaq determined IO Biotech no longer qualifies for listing under Rules 5101, 5110(b), and IM-5101-1.
- Company was notified of the delisting determination on March 31, 2026.
- Company did not appeal the delisting determination.
- Common stock was suspended from trading on April 7, 2026.
- Delisting becomes effective at the opening of trading on June 18, 2026.
Financial Impact
Total loss of exchange listing — common stock will trade over-the-counter only, severely reducing liquidity and investor access, and likely triggering accelerated terms for debt or derivatives. No dollar figure available in filing.
Risk Factors
- Complete illiquidity once delisted to OTC markets.
- Acceleration of debt covenants or convertible note redemption clauses.
- Potential involuntary dissolution or Chapter 7/11 filing given the company did not appeal delisting.
