Premarket movers: Generac, Nebius rally, BCB Bancorp sinks

Investing.com -U.S. stock index futures rose Thursday, as the Federal Reserve’s first interest rate hike in three years helped ease market anxiety over the central bank’s commitment to quelling inflation.

By 05:50 a.m. ET (09:50 GMT), the Dow futures contract had risen 369 points, or 0.7%, S&P 500 futures had gained 59 points, or 0.8%, and Nasdaq 100 futures had climbed 296 points, or 1.0%.

Here are some of the biggest premarket U.S. stock movers today:

Generac Holdings surged 33.7% in premarket trading after the power equipment maker announced a long-term agreement with Amazon to supply industrial backup generators for the technology giant’s global data centers.

The agreement calls for initial deliveries worth about $2.4 billion across 2027 and 2028, while the total value of the arrangement could reach as much as $8 billion.

Amazon will also receive a warrant to purchase about 1.69 million Generac shares at an exercise price of approximately $200.93 per share, representing nearly 3% of the company’s shares outstanding.

Nebius Group NV rose 11.1% in pre-open trading after the company notified customers of broad-based price increases across its on-demand GPU cloud services, effective Oct. 1.

Prices will rise by approximately 17% for H100 instances and roughly 21% for the latest Nvidia B300 GPU, while AMD EPYC Genoa CPU rates will increase by 25%.

The increases mark Nebius’ second round of price hikes within just a few months. The latest move points to continued strong demand for AI computing capacity, while also potentially strengthening the company’s pricing power and margin outlook. The price of Nebius’ B300 offering has now risen by approximately 56% cumulatively.

Arm Holdings gained 3.3% premarket after CEO Rene Haas said the company is increasingly confident it can convert more than $2 billion in customer demand for its artificial general intelligence, or AGI, CPU into revenue.

Haas said supply arrangements have improved since the company’s July update, while Arm has also signed multiyear agreements with customers.

The company has been moving beyond its traditional licensing model toward developing a complete self-designed data-center processor. Customer demand visibility for its AGI CPU had risen from about $1 billion in March to more than $2 billion by May.

Vicor climbed 11% in premarket trading after it entered into a non-exclusive license agreement with a leading AI original equipment manufacturer for its Vertical Power Delivery technology.

The technology is designed to deliver high current density from low-voltage power sources, with the agreement giving the AI OEM access to Vicor’s patented VPD technology.

BCB Bancorp fell 4.9% in premarket trading after the New Jersey-based community bank disclosed several developments late Wednesday that pointed to significant financial pressure.

The company priced an underwritten public offering of 11 million common shares for gross proceeds of $85.25 million, before underwriting discounts, commissions and other offering expenses. The new shares could dilute existing shareholders.

BCB Bancorp is also marketing approximately $210 million of problem loans and expects to move another $96 million of commercial real estate and cannabis-related loans into held-for-sale status.

The company currently expects to report a net loss of between $126.2 million and $136.1 million for the third quarter of 2026.

U.S.-listed gold miners moved higher in premarket trading, tracking a rebound in bullion prices after gold touched a near-six-week low a day earlier.

Spot gold was up 1.4% at $4,324.39 an ounce by 06:59 a.m. ET (10:59 GMT), supported by a softer U.S. dollar and retreating oil prices as investors assessed the Federal Reserve’s latest rate increase and the possibility of further tightening.

Newmont and Barrick Gold each gained about 1.2%. South African producers posted broader gains, with Harmony Gold up 3.7%, Gold Fields rising 2.3%, AngloGold Ashanti adding 2.4% and Sibanye-Stillwater climbing 1.3%.

Canadian miners also advanced, with Agnico Eagle Mines (NYSE: AEM) up 2.3% and Kinross Gold gaining 1.2%.
