SUBLEASE

In January 2026, the Company commenced a sublease of its facility located in Bowie, Maryland. The sublease has a term through March 31, 2031. Under the sublease, aggregate base rental income is approximately $2,300 over the sublease term. The sublease includes a 21-month rent abatement period during which base rent is partially or fully abated on a portion of the premises. In connection with the sublease, the Company provided the sublessee with an irrevocable letter of credit of approximately $315 to secure the sublessee’s benefit of the abated rent for the period of the rent abatement.

NASDAQ LISTING COMPLIANCE

On January 26, 2026, the Company received a deficiency letter (the “Notice”) from The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that, for the preceding 30 consecutive trading days, the closing bid price of its common stock had been below the $1.00 per share minimum required for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”).

The Notice has no immediate effect on the listing or trading of the Company’s common stock on The Nasdaq Capital Market. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has a compliance period of 180 calendar days from the date of the Notice, or until July 27, 2026, to regain compliance with the Minimum Bid Requirement. Compliance may be regained if the closing bid price of the Company’s common stock meets or exceeds $1.00 per share for a minimum of 10 consecutive trading days during the compliance period.

If the Company does not regain compliance by July 27, 2026, it may be eligible for an additional 180-calendar-day compliance period, provided it meets all other applicable initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Requirement. There can be no assurance that the Company will regain compliance during the initial or any additional compliance period.
