Halper Sadeh LLC said it is investigating seven proposed sale transactions involving Lantheus Holdings, Inc., Bowhead Specialty Holdings Inc., Safety Insurance Group Inc., MarineMax, Inc., Bowman Consulting Group Ltd., DoubleVerify Holdings, Inc. and Beazer Homes USA, Inc. for potential violations of federal securities laws and-or breaches of fiduciary duties to shareholders. The firm said it is assessing whether shareholders are receiving adequate consideration, whether insiders may receive financial benefits not available to ordinary shareholders, and whether deal terms could restrict superior competing offers. The transactions cited were Lantheus' sale to Curium US Holdings LLC for $102.50 per share in cash plus non-transferable contingent value rights worth up to $12.00 per share tied to specified commercial milestones through 2030, Bowhead's sale to American Family Mutual Insurance Company, S.I. for $34.00 per share in cash, Safety Insurance's sale to an affiliate of Mapfre S.A. for $105.00 per share in cash, MarineMax's sale to Safe Harbor Marinas for $53.00 per share in cash, Bowman Consulting's sale to Bernhard Capital Partners for $43.00 per share in cash, DoubleVerify's sale to Nielsen Holdings for $13.60 per share in cash, and Beazer Homes' sale to Dream Finders Homes, Inc. for $33.50 per share in cash. Halper Sadeh said it may seek increased consideration, additional disclosures, or other relief on behalf of shareholders.
