Halper Sadeh LLC is investigating whether certain officers and directors of Five Below, Inc. breached their fiduciary duties to shareholders. The firm encouraged long-term Five Below shareholders to discuss their rights and options, saying they may seek corporate governance reforms, the return of funds to the company, a court-approved financial incentive award, or other relief. Halper Sadeh said it handles matters on a contingent-fee basis, without out-of-pocket legal fees or expenses. The investigation does not establish that any breach occurred.
