RESEARCH FRONTIERS INC 8-K

What Happened Research Frontiers Inc. announced on June 2, 2026 that Nasdaq sent two deficiency notices saying the company no longer meets Nasdaq Capital Market listing standards: the $1.00 minimum closing bid price requirement and the $35 million Market Value of Listed Securities (MVLS) requirement. The bid-price review covered 30 consecutive business days from April 15, 2026 to June 1, 2026; the MVLS review covered 30 consecutive business days from April 20, 2026 to June 1, 2026. Nasdaq’s notices do not affect current listing or trading; REFR will continue trading on Nasdaq while it seeks to regain compliance.

Key Details

• Nasdaq rules cited: Rule 5550(a)(2) (minimum $1.00 bid) and Rule 5550(b)(2) (minimum $35M MVLS).
• Compliance period: 180 calendar days, giving the company until November 30, 2026 to regain compliance.
• Recovery requirements: each metric must meet its threshold for at least ten consecutive business days during the compliance period.
• Company stance: intends to monitor stock price and MVLS and pursue options to regain compliance; currently does not intend to effect a reverse stock split. Nasdaq noted the company also does not meet alternative standards under Rules 5550(b)(1) (stockholders’ equity) and 5550(b)(3) (net income).

Why It Matters A failure to regain compliance by November 30, 2026 could lead to delisting proceedings, which can reduce liquidity and make the stock harder to trade. For investors, the immediate effect is limited—the shares continue to trade—but the notices signal the company must improve market valuation or take corporate actions to retain its Nasdaq listing. The company’s stated goal is to regain compliance through improved market performance; there is no assurance it will succeed.
