American corporation providing marine services to the offshore petroleum industry
* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($3.9m this quarter). Holder counts are more reliable. Shares outstanding: 49.8m as of 2026-07-31, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $66.69. Options: 12 managers hold calls ($43.5m notional), 11 hold puts ($43.6m).
