Quantum Corporation (NASDAQ:QMCO): Up 21.25% Pre-Market on Fiscal Second-Quarter 2027 Results and Guidance

Quantum Corporation (NASDAQ:QMCO) was quoted at USD 20.60 on Tuesday, November 10, 2026, a 21.25% rise against a calculated previous close of USD 16.99. The November 9 release showed revenue of USD 89.6 million, up 42.9% from USD 62.7 million, GAAP gross Margin of 41.0% and adjusted EBITDA of USD 11.1 million. Third-quarter revenue guidance is USD 91.0 million, plus or minus USD 2 million, alongside a record Backlog of nearly USD 100 million. The GAAP net loss was USD 44.8 million, or USD 1.14 per share, which includes a USD 51.6 million non-cash Warrant charge. Shares outstanding rose to 39,541 thousand, so calculated Market Value is near USD 814 million. The 52-week range sits between USD 4.19 and USD 35.65. For broader perspective, warrant liabilities of USD 83.3 million can swing GAAP results as the share price moves. Pre-market trade is light, spreads may be broad, and an Earnings gap could reverse at the open.

AAON, Inc. (NASDAQ:AAON): Up 20.88% Pre-Market on Third-Quarter Results and a Raised Outlook

AAON, Inc. (NASDAQ:AAON) was quoted at USD 76.00, a 20.88% gain against a calculated previous close of USD 62.87. The company's November 9 release showed net sales up 84.1% to USD 707.4 million, diluted EPS of USD 0.83 compared with USD 0.37, and a raised 2026 sales growth outlook of 72% to 75% from 55% to 60%. Backlog was USD 1,854.5 million, up 40.5% from a year earlier but 5.9% lower than at June 30. The release also restated the first two quarters of 2026, a point that may draw scrutiny. On 82,459,251 shares, calculated market value is near USD 6.27 billion, and the 52-week range of USD 54.73 to USD 150.46 shows the price still far below its high. Revolver Debt was USD 386.7 million against USD 3.7 million of total cash. Pre-market trade is light, and a jump this size could reverse at the open.

Sanmina Corporation (NASDAQ:SANM): Up 19.95% Pre-Market on Fiscal Fourth-Quarter Results and 2027 Guidance

Sanmina Corporation (NASDAQ:SANM) was quoted at USD 179.50, a 19.95% rise against a calculated previous close of USD 149.65. Fiscal fourth-quarter revenue reached USD 3.86 billion versus USD 2.10 billion, with non-GAAP EPS of USD 4.43 and GAAP EPS of USD 2.14. Fiscal 2027 guidance calls for revenue of USD 17.5 billion to USD 19.5 billion and non-GAAP EPS of USD 15.50 to USD 17.50. For broader perspective, shares often gap higher when guidance beats forecasts, and the USD 2.29 per share difference between GAAP and non-GAAP EPS, calculated, makes the reconciliation worth attention. Published market data listed a market value of USD 8.02 billion and a 52-week range of USD 118.10 to USD 288.68, so the price sits 37.8% below the high, calculated. Long-term debt climbed to USD 1.92 billion from USD 283.0 million. Light Volume and broad spreads could reverse the gap at the open.

Senseonics (NASDAQ:SENS): Up 13.27% Pre-Market on Third-Quarter Results and Higher 2026 Guidance

Senseonics (NASDAQ:SENS) was quoted at USD 11.10, a 13.27% gain from a calculated previous close of USD 9.80, or about USD 1.30 per share. Third-quarter 2026 revenue released on November 9 was USD 19.6 million, up roughly 140% from USD 8.1 million, with gross margin near 62%. Management lifted full-year revenue guidance to USD 68 million to USD 70 million from USD 62 million to USD 66 million. The net loss widened to USD 32.7 million, or USD 0.50 per share, from USD 19.5 million, as selling, general and administrative expense reached USD 32.3 million. Cash was USD 126.6 million against USD 55.0 million of principal debt. With 54,775,503 shares, calculated market value is near USD 608 million, although the weighted-average count of 65,736,278 does not reconcile and should be checked. A 52-week range and average volume were not verified. Financing could dilute holders at Senseonics (NASDAQ:SENS), and light volume could reverse the gain.

Ameresco (NYSE:AMRC): Up 8.46% Pre-Market on Third-Quarter Results and a Record Backlog

Ameresco (NYSE:AMRC) was quoted at USD 24.35, a USD 1.90 per share gain or 8.46% against a calculated previous close of USD 22.45. Published coverage of the November 9 release cites third-quarter revenue of USD 580 million, up 10%, an earnings beat and a record backlog of USD 7.2 billion. The profit outlook was strong and the revenue outlook mixed, which may account for why this is the smallest gain on the list. For broader perspective, a record backlog supports revenue visibility even when a quarter falls short. At about 53.07 million shares, calculated market value is near USD 1.29 billion, and the shares remain well below the 52-week high of USD 42.83. Pre-market prints rest on only a few hundred thousand shares, with broad spreads, project financing adding leverage, and the quote able to differ from the 9:30 a.m. ET open.

Where Things Stand

Quantum Corporation (NASDAQ:QMCO) tops the earnings-day gainers at +21.25%, with AAON close behind at +20.88% and Sanmina at +19.95%, while Senseonics (+13.27%) and Ameresco (+8.46%) trail further back. The shared thread is a Quarterly Report released on November 9, 2026 that showed revenue growth or raised guidance. Light pre-market trade in these names can flip at the opening bell, with few shares changing hands, wide spreads and a first regular session that may reprice each stock. The figures come from a pre-market screener snapshot of November 10, 2026.
