Rosen Law Firm said on Sept. 21, 2026, that it was investigating potential civil securities claims involving shareholders of J.B. Hunt Transport Services, Inc. and Build-A-Bear Workshop, Inc. The J.B. Hunt investigation followed a Sept. 16 CNBC report that the company's shares plunged 10% after a warning that third-quarter earnings would fall, including about $25 million in additional costs. Build-A-Bear trades on the NYSE under ticker BBW. The firm said it was preparing prospective class actions seeking recovery of investor losses and that eligible investors could participate through contingency-fee arrangements without upfront fees or costs.
