Fajasy on X

I compared the 8-K on Quantum’s $QMCO CFO firing to the one on its chief accounting officer’s exit in August. $QMCO terminated William White as CFO on October 9, 2026, effective immediately, eight months after appointing him on February 2, 2026. When I first wrote up $QMCO on May 6, White was its newly appointed CFO, after the seat had been empty since August 2025. The 8-K gives no reason, and I found no press release about the firing on $QMCO’s investor relations site. Instead, the 8-K says $QMCO expects to file its September-quarter 10-Q on time. The filing also says $QMCO expects to meet or exceed its guidance for the quarter, even though it was still “early in its financial closing process.” Chief accounting officer Hiral Patel took over as principal financial officer, so she now signs off on $QMCO’s financial statements with the CEO. Patel only joined $QMCO on September 1, after the company decided on August 11 to replace Laura Nash as chief accounting officer. The 8-K on Nash says there are “no disagreements” between her and the company, but the one on White doesn’t say either way. So within two months, $QMCO replaced both of its top finance officers. $QMCO’s June-quarter 10-Q still reports material weaknesses (the most serious kind of gap in a company’s financial reporting controls) in revenue recognition, inventory, and income taxes. It also says $QMCO “lacked sufficiently qualified staff or resources to perform control activities.” None of the weaknesses has led to a material misstatement, but $QMCO has restated its financial statements before, in May 2024 and again in August 2025. In my May 6 write-up, I listed restatements as a risk that could break the story, and wrote that a third “would be a serious credibility hit.” $QMCO expected to fix one of its three revenue weaknesses, the schedules that set when service revenue is recognized, by the end of the September quarter. Its June-quarter 10-Q was also officially filed on August 11, a day after its 40-day deadline, and its FY2026 10-K needed a notice of late filing in June. So with open material weaknesses, a history of restatements, and a 10-Q filed a day late in August, I’d rather see the September-quarter 10-Q, due November 9, before taking $QMCO at its word.
