Knife River Corporation filed an 8-K stating it issued a press release announcing third quarter 2025 earnings. The company furnished the release to the SEC under Items 2.02 (Results of Operations and Financial Condition) and 7.01 (Regulation FD Disclosure).

Knife River's Schedule 13G discloses that T. Rowe Price Associates, Inc. beneficially owns 2,983,797 shares of common stock, equal to 5.3% of the class. The filing shows sole voting power over 2,975,460 shares and sole dispositive power over 2,983,797 shares. The report states these securities were acquired and are held in the ordinary course of business and are not held to influence control of the issuer, which is why a Schedule 13G (passive investor) was used. In short, this is a material institutional stake disclosed as passive ownership rather than an active control position.
