Rosen Law Firm investigates potential fiduciary duty breaches by directors and officers of listed supply-chain software group Manhattan Associates

Rosen Law Firm, a US investor-rights practice specialising in securities class actions and shareholder derivative litigation, has announced an active investigation into potential breaches of fiduciary duties by the directors and officers of Manhattan Associates, Inc. (NASDAQ: MANH), a supply-chain software company listed on Nasdaq. The firm is inviting current shareholders to come forward, and two separate sources confirm the investigation is live as of 13 June 2026. No formal proceedings have been filed and no specific factual allegations have been disclosed beyond the investigation announcement. Rosen Law Firm has a track record in this area — it was ranked first by ISS Securities Class Action Services for the number of securities class-action settlements in 2017 and has consistently ranked in the top four since 2013. The firm's model is to investigate, then file a shareholder derivative or class action if the evidence supports it. For UK-focused law students, the story illustrates a standard US mechanism: plaintiff firms proactively investigate listed companies after share-price movements or governance concerns, with a view to seeking class certification or derivative standing. The lead-plaintiff deadline process — under which investors must move the court by a fixed date — is a procedural feature of US securities litigation with no direct English-law equivalent, though comparable shareholder-activism pressure is increasingly visible in the UK through the Companies Act 2006 unfair prejudice and derivative claim routes.
