FAQ

What did Transocean (RIG) executive chair Jeremy Thigpen report in this Form 4?

Jeremy Thigpen reported vesting and exercises of long-term incentive awards plus a tax-related share disposition. He acquired several blocks of registered shares on March 1, 2026, and later disposed of 245,556 shares on March 3, 2026, to cover associated tax withholding obligations.

How many Transocean (RIG) shares did Jeremy Thigpen dispose of for taxes?

He disposed of 245,556 registered shares at $6.12 per share to satisfy tax-withholding obligations. The filing classifies this as a tax-withholding disposition rather than an open-market sale, reflecting shares withheld upon award vesting rather than a discretionary secondary-market transaction by the executive chair.

How many Transocean (RIG) shares does Jeremy Thigpen own after these transactions?

After the reported transactions, Jeremy Thigpen directly owns 2,614,548 registered shares of Transocean. This figure reflects the net result of multiple award vestings and a tax-withholding share disposition recorded in early March 2026 under the company’s long-term incentive plan arrangements.

What type of awards vested for Transocean (RIG) executive Jeremy Thigpen?

The filing describes restricted units that are 1-for-1 share equivalents granted under Transocean’s long-term incentive plan. Portions of grants from February 2023, February 2024, and February 2025 vested on March 1, 2026, giving Thigpen the right to receive registered shares.

Are there remaining unvested restricted units for Jeremy Thigpen at Transocean (RIG)?

Yes. Footnotes state remaining restricted share units vest in future years. For example, 245,640 restricted units vest on March 1, 2027, and additional units of 171,821 and 171,822 vest on March 1, 2027 and March 1, 2028, respectively, under prior long-term incentive grants.

Was Jeremy Thigpen’s share disposition in Transocean (RIG) an open-market sale?

No. The Form 4 labels the March 3, 2026 transaction with code F and notes shares were sold upon vesting to satisfy tax-withholding obligations. This indicates a tax-withholding disposition tied to equity award vesting, not a discretionary, open-market sale decision by the executive.
