Halper Sadeh LLC said it is investigating the proposed sales of MarineMax, Inc., Beazer Homes USA, Inc. and Accelerant Holdings over potential violations of federal securities laws and possible breaches of fiduciary duties to shareholders. The firm said the transactions could provide insiders with financial benefits unavailable to ordinary shareholders and may include terms that could restrict superior competing bids. The deals under review are MarineMax's sale to Safe Harbor Marinas for $53.00 per share in cash, Beazer Homes USA's sale to Dream Finders Homes, Inc. for $33.50 in cash per share, and Accelerant Holdings' sale to Thoma Bravo for $20.25 per share in cash. Halper Sadeh said it may seek increased consideration, additional disclosures and information, or other relief on behalf of shareholders.
