United States Antimony Corporation commenced an at-the-market offering of up to $400,000,000 of common stock, to be sold from time to time through A.G.P./Alliance Global Partners and B. Riley Securities as agents or principals. Sales may be made pursuant to Rule 415(a)(4) with no minimum amount required.
The company will pay the Agents up to 3.0% of the gross sales price per share and plans to use any net proceeds to acquire antimony and other critical mineral inventory, expand leasehold positions in Alaska and Montana, pursue acquisitions, potentially increase capacity at the Madero Smelter in Mexico, and for general working capital.
As context, the last reported sale price was $16.71 per share on October 13, 2025, and shares outstanding were 138,878,411 as of that date. The filing illustrates potential dilution: at an assumed price of $16.71, pro forma as adjusted net tangible book value would be $3.24 per share, implying $13.47 per-share dilution to new investors.
United States Antimony Corporation is conducting a primary offering of 2,377,657 shares of common stock at $10.50 per share, for gross proceeds of $24,965,398.50.

Shares outstanding are expected to increase to 138,878,411 from 136,500,754 as of October 9, 2025. The company plans to use the funds to buy additional antimony and other critical mineral inventories, expand leasehold positions in Alaska and Montana, pursue acquisitions of critical mineral businesses or properties, potentially increase capacity at its Madero smelter in Mexico, and for general working capital. The company highlights that new investors will face immediate dilution, with pro forma net tangible book value moving to $1.00 per share versus the $10.50 offering price.

The deal is a best-efforts placement through A.G.P./Alliance Global Partners to a single purchaser, with the placement agent earning a 7.0% cash fee, partially offset by a credit.
The company expects net proceeds of approximately $25.4 million (about $25.56 million after fees, expenses and the credit), which it plans to use for working capital, buying additional antimony and other critical mineral inventory, expanding leasehold positions, potential acquisitions of critical mineral assets or companies, and possible expansion of its Madero smelter in Mexico above its 200‑ton‑per‑month capacity.
Shares outstanding were 131,092,887 as of October 3 2025 and are expected to be 134,592,887 after the offering. The company highlights that new investors will face immediate dilution, as pro forma net tangible book value would rise to $0.78 per share versus the $7.50 offering price.
