Rosen Law Firm is investigating potential securities claims on behalf of J.B. Hunt Transport Services shareholders over allegations that the company may have issued materially misleading business information. The inquiry follows a September 16, 2026 CNBC report that J.B. Hunt stock plunged 10% after the company warned third-quarter earnings would fall. The report said J.B. Hunt's Chief Financial Officer expected recruiting, advertising, onboarding, training and sign-on bonuses to add about $25 million in costs in the third quarter compared with the second quarter. J.B. Hunt shares fell sharply in intraday trading that day. Rosen Law Firm is preparing a class action seeking recovery of investor losses and says eligible investors may participate through a contingency fee arrangement without paying out-of-pocket fees or costs.
