Quantum Corp. /DE/ reported an insider ownership change involving Laura A. Nash on July 2, 2026, in the company’s common stock. The Form 4, filed July 7, 2026, describes an automatic, non-discretionary sale of shares to satisfy tax withholding obligations tied to the vesting of restricted stock units. The restricted stock units involved were originally granted on July 1, 2023. According to the filing note, the shares sold were not discretionary trades by Nash, but were automatically sold to cover taxes triggered by the RSU vesting event. The sale occurred on July 2, 2026. The filing states that the shares were sold at a weighted average price, as part of block trades for multiple Quantum security holders. The reported execution prices ranged from $10.48 to $10.53 per share. Nash undertook to provide detailed information about the exact number of shares sold at each price upon request by the SEC, Quantum, or a Quantum securityholder. The securities covered by the Form 4 are also subject to a Lock-Up Letter Agreement between Quantum and Nash dated June 1, 2026. The filing notes that the transaction is subject to clause (h) of that agreement, indicating that the tax-withholding sale was treated under an exception or applicable provision of the lock-up arrangement. The document excerpt does not include the Form 4 transaction table that would normally show the exact share count sold, transaction code, or Nash’s beneficial ownership after the transaction. Based on the explanatory notes provided, the key reported action is a tax-related automatic sale connected to vested RSUs, rather than an elective insider sale. The filing was signed on Nash’s behalf by Tara Ilges, attorney-in-fact, on July 7, 2026.
