Quantum Corporation (Nasdaq: QMCO), a provider of data management solutions for AI and unstructured data, has announced preliminary unaudited financial results for its fiscal second quarter of 2026, which ended September 30, 2025. The company expects to release its complete financial results by mid-November 2025. Based on preliminary figures, Quantum anticipates operating expenses of $32.0 million for the quarter. Adjusting for certain items, the company reports non-GAAP adjusted operating expenses of $25.0 million. This non-GAAP measure excludes stock-based compensation expense of $0.5 million, restructuring charges of $3.5 million, amortization of acquisition-related intangible assets of $0.0 million, and non-recurring project costs of $3.0 million. Quantum emphasizes that these results are preliminary and unaudited, and subject to change as the company completes its financial close process and undergoes audit review. Final financial statements may reflect adjustments that could be material. The company does not intend to update these figures prior to filing its Form 10-Q with the U.S. Securities and Exchange Commission, except as required by law. The forward-looking statements in this release include projections about financial performance and future business trends. These statements are based on current expectations and involve risks and uncertainties that could cause actual results to differ materially. Such risks include the completion of the financial close, changes in assumptions, potential adjustments to preliminary data, macroeconomic conditions, supply chain disruptions, competitive pressures, execution challenges, product development timelines, and the impact of the transaction with Dialectic, among others. Additional risks are detailed in Quantum’s SEC filings, including its Annual Report on Form 10-K filed on August 26, 2025. The company also provides non-GAAP adjusted operating expenses as a supplemental measure to help investors assess core business performance. This metric excludes specific non-cash and one-time items to allow for more consistent period-to-period comparisons. However, non-GAAP measures have limitations and should not be used as a substitute for U.S. GAAP financial results. Other companies may calculate similar metrics differently, reducing comparability.
