Stardust Power Inc. Announces Exercise of Over-Allotment Option from Recent Public Offering

GREENWICH, Conn., June 26, 2025 (GLOBE NEWSWIRE) — Stardust Power Inc. (NASDAQ: SDST) (the “Company”), an American developer of battery-grade lithium products, today announced that the underwriter of its previously announced public offering of common stock has exercised its option to purchase an additional 1,100,000 shares of Common Stock, resulting in additional gross proceeds of approximately $220,000. After giving effect to the exercise of the over-allotment option, the gross proceeds from the offering increased to approximately $4.52 million, before deducting underwriting fees and other estimated offering expenses payable by the Company.
