Rosen Law Firm is investigating potential securities claims involving BlackRock, Inc. mutual funds over allegations that BlackRock may have issued materially misleading business information to the investing public. The Aug. 10, 2026 notice says purchasers of BlackRock mutual funds may be entitled to compensation through a contingency-fee arrangement and that the firm is preparing a class action seeking recovery of investor losses. The update materially changes an already inconsistent topic record that previously captured Rosen notices naming Hyliion Holdings Corp., GoDaddy Inc. shareholders, and investors in FLOW cryptocurrency linked to Flow Foundation. The Hyliion version said the inquiry followed a short-seller report, while the FLOW version said purchasers on or before December 27, 2025 who held through December 29, 2025 should contact the firm. The latest release directs potential claimants to a BlackRock-specific case page or to contact Phillip Kim, Esq., underscoring that the available records reflect multiple Rosen investigation notices naming different targets rather than a single clearly identified case.
