Stock futures were largely unchanged in premarket trading on Thursday, following a strong tech rally that pushed the Nasdaq to a new record high in the previous session.

Here are some of Thursday's biggest stock movers:

BIGGEST STOCK GAINERS

* RICHARDSON ELECTRONICS (NASDAQ:RELL [https://seekingalpha.com/symbol/RELL]) +22% - Shares jumped higher after the company reported better-than-expected FQ1 results, driven by strong growth in its semiconductor wafer fab business. Excluding the divested Healthcare unit, net sales rose by 6.8% Y/Y. The company's focus on a more profitable sales mix and disciplined cost control was highly effective, leading its operating income to more than triple compared to the prior year. CEO Edward J. Richardson noted the solid results reflect the company's value proposition and market diversity, adding that they generated positive operating cash flow for the sixth consecutive quarter and are confident in delivering improved performance for the entirety of FY2026.

BIGGEST STOCK LOSERS

* APOGEE THERAPEUTICS (NASDAQ:APGE [https://seekingalpha.com/symbol/APGE]) -10% - Shares plunged after the company priced its public offering at $41 per share, raising approximately $300M in gross proceeds. The offering comprises 6.95M common shares and 365,853 pre-funded warrants, both priced at $41, with the warrants exercisable immediately. The deal, expected to close on October 10, 2025, also grants underwriters a 30-day option to buy up to 1.1M additional shares. Apogee said proceeds will support advancement of its clinical-stage biologics pipeline targeting inflammatory and immunology markets.
* AZZ (NYSE:AZZ [https://seekingalpha.com/symbol/AZZ]) -6% - Shares slid after the company missed FQ2 expectations and presented a mixed outlook for the full year. While AZZ maintained its FY2026 guidance, the midpoint for its projected sales of $1.675B came in slightly above the consensus of $1.66B. However, the midpoint for adjusted diluted EPS of $6.00 missed the analyst consensus of $6.04. The maintained guidance reflects expectations for anticipated market conditions, lower interest expense, and a 24% effective tax rate, while excluding any M&A activity or federal regulatory changes.
