Stardust Power Inc. Announces Closing of $4.3 Million Underwritten Public Offering

GREENWICH, CONNECTICUT, June 18, 2025 (GLOBE NEWSWIRE) — Stardust Power Inc. (NASDAQ: SDST) (the “Company”), an American developer of battery-grade lithium products, today announced the closing of its previously announced underwritten public offering. Gross proceeds to the Company were approximately $4.3 million, before deducting underwriting fees and other offering expenses payable by the Company. The offering closed on June 18, 2025.

The offering consisted of 21,500,000 shares of common stock (“Common Stock”). The public offering price per share of Common Stock was $0.20. In addition, the Company has granted Aegis Capital Corp. (“Aegis”) a 45-day option to purchase up to an additional 3,225,000 shares of Common Stock, representing 15.0% of the number of shares of Common Stock sold in the offering solely to cover over-allotments, if any.

If the over-allotment option is exercised in full, aggregate gross proceeds to the Company are expected to total approximately $4.9 million. These funds will support the completion of the Definitive Feasibility Study (DFS/FEL-3), a transformational milestone for Stardust Power. The DFS will provide detailed engineering, comprehensive capital expenditure estimates, and a clearly defined scope of build for the Company’s proposed lithium processing facility in Muskogee, Oklahoma, laying a strong foundation for final investment decision (FID) efforts and bringing the project significantly closer to securing financing for the construction of Phase 1.
