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.

Why this matters

Shareholder derivative and fiduciary duty investigations of the kind Rosen Law Firm is pursuing activate corporate governance, securities litigation, and D&O (directors and officers) insurance practice simultaneously. For listed technology companies, an announced investigation — even before formal proceedings — can create disclosure obligations and trigger indemnity clauses. The US plaintiff-firm model of pre-litigation investigation is distinct from English practice, but City firms advising US-listed clients or dual-listed issuers regularly need to advise on parallel risk across both jurisdictions. With no specific allegations yet disclosed, confidence in the legal framing remains limited to the business facts in the sources.

Interview prep

Soundbite

Pre-litigation investigation announcements force listed companies to weigh disclosure obligations before any claim is even filed.

Question you might get

“How does the US lead-plaintiff mechanism in securities class actions differ from English derivative claims under the Companies Act, and what practical advice would you give a board facing an investigation announcement of this kind?”

Full answer

Rosen Law Firm has announced an investigation into potential fiduciary duty breaches by the board and officers of Manhattan Associates, a Nasdaq-listed supply-chain software company. Even at the investigation stage — before formal proceedings — this creates immediate governance pressure: the company must assess whether a disclosure obligation is triggered, review D&O insurance cover, and consider whether the board needs independent legal advice. This reflects a broader US trend of plaintiff firms using pre-filing investigation announcements to attract lead plaintiffs and maximise leverage. UK practitioners advising dual-listed or US-listed clients need to understand how these parallel obligations interact, as a US class action can run concurrently with a UK unfair prejudice petition. The risk for directors is that investigation announcements, however unsubstantiated, accelerate board-level governance scrutiny.
