The board of directors declared a dividend of one preferred share purchase right for each outstanding share of common stock and adopted a stockholder rights plan effective November 8, 2026. The plan triggers if any person or group acquires 15% or more of the company's common stock without board approval, imposing significant penalties on such an acquiring person. Rights are payable to stockholders of record on November 19, 2026, and expire on November 7, 2027. The adoption responds to recent accumulation by a single stockholder that currently owns approximately 14.7% of the outstanding common stock.
