Filed Pursuant to Rule 424(b)(5) Registration No. 333-272985 Prospectus Supplement
(To Prospectus Dated July 19, 2023) 1,508,462 Shares of Common Stock
Pre-Funded Warrants to Purchase up to 3,491,538 Shares of Common Stock Pursuant to this prospectus supplement and the accompanying prospectus, we are offering in a registered direct offering to certain purchasers (i) 1,508,462 shares of our common stock, par value $0.001 per share at a purchase price of $10.00 per share, and (ii) pre-funded warrants to purchase 3,491,538 shares of our common stock (the “pre-funded warrants”) and the shares of common stock issuable from time to time upon exercise of the pre-funded warrants. We are offering pre-funded warrants in lieu of shares of our common stock to investors whose purchase of shares of common stock in this offering would otherwise result in such investor, together with its affiliates, beneficially owning more than 4.99% (or, at the election of the investor, up to 9.99%) of our common stock. The per share exercise price for the pre-funded warrants will be $0.01, and the pre-funded warrants are immediately exercisable and may be exercised at any time until all of the pre-funded warrants are exercised in full. Our common stock is quoted on The Nasdaq Global Select Market (“ Nasdaq ”) under the symbol “GSIT.” On October 20, 2025, the last reported sales price of our common stock on Nasdaq was $12.97 per share. The trading price of our common stock has fluctuated, and is likely to continue to fluctuate, due to a variety of factors. There is no established public trading market for the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the pre-funded warrants on Nasdaq, any other national securities exchange or any other nationally recognized trading system. We are a “smaller reporting company” as defined under the federal securities laws and are subject to reduced public company reporting requirements. We have retained Needham & Company (the “ Placement Agent ”) as our placement agent in connection with this offering with respect to certain purchasers. The Placement Agent is not purchasing or selling any of the securities offered by this prospectus supplement, nor is it required to arrange the purchase
