Research Frontiers receives two Nasdaq deficiency notices over bid price and market value
Research Frontiers received two Nasdaq deficiency letters on June 2, 2026, saying its stock has closed below the $1.00 minimum bid price and its market value of listed securities has fallen below $35 million. The company has until November 30, 2026 to regain compliance, and the stock continues to trade on the Nasdaq Capital Market under REFR, but there is no assurance it will regain compliance.
Key points
- Bid price notice: closing bid below $1.00 for 30 consecutive business days from April 15 to June 1, 2026
- MVLS notice: market value of listed securities below $35 million for 30 consecutive business days from April 20 to June 1, 2026
- Compliance deadline: November 30, 2026; regaining compliance requires ten consecutive business days at or above the thresholds
- The company does not currently intend to effect a reverse stock split to regain compliance
