United States Antimony (UAMY) CFO Richard Isaak Receives Awards

What Happened Richard R. Isaak, Chief Financial Officer of United States Antimony Corp. (UAMY), received two equity awards on January 15, 2026: 73,086 restricted stock units (RSUs) and stock options covering 82,169 shares. No purchase price or immediate cash value is reported for these awards — they are grants of compensation rather than open-market purchases or sales.

Key Details

  • Transaction date: January 15, 2026; Form 4 filed January 27, 2026 (filed late relative to the typical 2-business-day deadline).
  • RSUs: 73,086 RSUs granted. One-third (24,362 shares) vested on January 15, 2026; the remaining two one-third tranches vest on January 15, 2027 and January 18, 2028, subject to continued service. (Footnote F1)
  • Options: 82,169 stock options granted. Options vest only upon satisfaction of specified performance measures at any time during the 10-year term, and are also subject to continued service requirements. (Footnote F2)
  • Prices/values: No exercise price or per-share value reported in the filing (derivative awards listed as N/A).
  • Shares owned after transaction: Not specified in the filing.
  • Filing timeliness: The Form 4 was filed 12 days after the grant date, which is later than the usual 2-business-day reporting requirement.

Context RSU and option grants are a common form of executive compensation and do not represent an open-market buy or sell. RSUs convert into common shares if and when they vest; options require meeting performance conditions (and exercise) before creating an ownership stake. Because these are awards, they should be viewed as compensation disclosures rather than direct signals of the insider buying or selling stock.
