The largest shareholder of Seacor Marine Holdings has urged the Houston-based offshore-vessel operator’s board to put the company up for sale. In a letter sent Monday, Pointillist Family Office — which holds about 7.2% of Seacor — argued the stock badly undervalues the fleet, pegging net asset value at more than $20 a share against Monday’s $6.63 opening price (a market cap near $180 million).

Fund managing member Jorey Chernett said Seacor’s “young and technically advanced” fleet, which serves offshore energy and wind projects, could be worth more than $1 billion on appraisal benchmarks, and blamed the discount on the company’s failure to monetize assets and generate free cash flow even during an industry upcycle. He pressed the board to retain an independent advisor and weigh strategic alternatives — a full sale to a strategic buyer or consolidator, or a structured sale of the fleet.

Seacor shares fell 8% in 2025 but are up about 9.8% so far in 2026. A company representative did not immediately respond to a request for comment.
