United States Lime & Minerals, Inc. is holding its 2026 annual meeting on May 1, 2026, asking shareholders to elect seven directors and approve, on an advisory basis, the company’s executive compensation. Shareholders of record on March 13, 2026, with 28,670,056 common shares outstanding, may vote.
