Quantum Corporation (NASDAQ:QMCO) shares surged about 10% on Thursday after the company reported preliminary third-quarter fiscal 2026 results that came in above its previously issued revenue outlook.
The artificial intelligence and unstructured data solutions provider said preliminary revenue for the quarter ended December 31, 2025, totaled roughly $72.7 million, exceeding the high end of its guidance range of $67 million, plus or minus $2 million.
Based on the preliminary, unaudited figures, Quantum posted a GAAP gross margin of approximately 38% for the quarter. GAAP operating expenses were about $28.1 million, while non-GAAP adjusted operating expenses came in at roughly $26.9 million, both within the company’s earlier guidance.
Quantum said it expects to publish its full fiscal third-quarter 2026 financial results by mid-February 2026. The stronger-than-expected preliminary revenue appears to have boosted investor confidence in the data management specialist, driving the sharp rise in the stock during Thursday’s trading session.
