AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What equity awards did OII executive Martin McDonald report on this Form 4?

Martin McDonald reported grants of performance stock units and restricted stock units, each totaling 10,111 units. The performance units can convert into up to two shares each, while the restricted units convert one-for-one into Oceaneering International (OII) common stock.

How do the performance stock units granted to the OII executive work?

Each performance stock unit gives a contingent right to receive between zero and two shares of common stock. Actual shares earned depend on achieving specific performance targets, making these awards tied directly to Oceaneering International’s future performance goals.

When do the restricted stock units granted to OII’s Martin McDonald vest?

The restricted stock units vest in three equal annual installments on February 20, 2027, 2028, and 2029. As each installment vests, the units convert into common shares of Oceaneering International (OII), strengthening the executive’s long-term equity stake.

Did the OII executive pay cash for the performance or restricted stock units?

No cash was paid for these awards; the transaction price per unit was reported as $0.00. The units are equity compensation grants, providing contingent rights to receive Oceaneering International common shares over time, subject to vesting and performance conditions.

Are previously granted OII restricted stock units included in this Form 4 total?

The reported totals exclude unvested restricted stock units granted in previous years. Earlier awards were already reported in Table I of prior Forms 4, so this filing focuses only on the newly granted 2026 restricted stock unit award to Martin McDonald.

How many derivative units does the OII executive hold after these Form 4 grants?

After the reported grants, the Form 4 shows 10,111 performance stock units and 10,111 restricted stock units in the relevant derivative columns. These reflect only the newly reported awards, not prior-year unvested restricted stock unit holdings for Martin McDonald.
