Quantum Corp. (QMCO) received a Nasdaq deficiency notice on 17 Jul 2025 for not filing its Form 10-K for FY-end 31 Mar 2025 within the required period, violating Listing Rule 5250(c)(1).
The company had already filed a Form 12b-25 on 30 Jun 2025, citing the need for extra time to review revenue-recognition accounting, including standalone selling-price analyses for certain contracts. Management says it is “working diligently� to complete the review and submit the annual report within Nasdaq’s cure timeline.
Immediate impact: QMCO shares remain listed and continue trading on the Nasdaq Global Market while the company remedies the filing lapse. Continued listing is subject to satisfying other Nasdaq requirements.
On 23 Jul 2025 QMCO issued a press release (Exhibit 99.1) disclosing the notice. No financial results, guidance, or other material transactions were included in the 8-K.
