Diamond Offshore Reports First Quarter 2024 Results

HOUSTON, May 7, 2024 — Diamond Offshore Drilling, Inc. (NYSE: DO) today reported the following results for the first quarter of 2024:

Bernie Wolford, Jr., President and Chief Executive Officer, stated, “The demand landscape remains compelling for our business. The high-specification deepwater rig supply-demand balance continues to tighten, which is resulting in strong contracting conditions that have already begun to benefit our fleet. The average contract dayrate across our fleet will notably increase as we transition to our recently awarded contracts.”

New Contract Awards and Marketing Rights

As previously disclosed, the Company secured $713 million in new contract awards in the first quarter, including two-year contract extensions for the Ocean BlackLion and Ocean BlackHornet in the U.S. Gulf of Mexico at leading-edge dayrates as well as additional plug and abandonment (“P&A”) work for the Ocean Patriot, which is currently underway.

In addition, after quarter-end, the Company signed an estimated 30-day, one-well contract for the Ocean BlackRhino, representing approximately $18 million in total contract value that will be pre-paid prior to commencement. The work is scheduled to begin immediately after the rig’s Special Periodical Survey and Managed Pressure Drilling upgrade later this year.

Further, the Company has recently secured the marketing rights for three 7^th generation drillships. The Company entered into an agreement with the owner of the West Dorado and West Draco to market the rigs in Brazil, Latin America, West Africa, Malaysia, and Indonesia. In addition, the Company agreed with the owner of the former West Libra, now known as the Tidal Action, to market the rig in the U.S. Gulf of Mexico.

Financial Results

Revenue for the first quarter of 2024 totaled $275 million compared to $298 million in the fourth quarter of 2023. The decrease in revenue quarter-over-quarter was primarily driven by the reduction in revenue for the Ocean GreatWhite following its equipment incident in the first quarter and the West Auriga’s return to the rig owner at the end of February upon expiration of the rig’s charter. The decrease in revenue was partially offset by a full quarter of revenue for the Ocean BlackHawk and Ocean Courage at higher dayrates after completion of shipyard upgrades and contract preparation work in the fourth quarter of 2023.

Contract drilling expense for the first quarter of 2024 was $184 million, a $5 million decrease from the prior quarter. The decrease in contract drilling expense was primarily due to lower charter and other operating expenses attributable to the two managed rigs and the absence of the well control equipment efficiency bonus accrued in the fourth quarter of 2023. The reduction in expense was partially offset by incremental contract drilling expense for the Ocean Courage and Ocean BlackHawk, both of which operated for the entire first quarter of 2024, and the recording of $7.6 million in insurance deductible associated with the Ocean GreatWhite’s equipment incident.

General and administrative expenses were flat at $19 million for both the first quarter of 2024 and the fourth quarter of 2023.

For the first quarter of 2024, the Company recognized a net tax benefit of $3.2 million compared to tax expense of $174 million for the fourth quarter of 2023. The benefit in 2024 is inclusive of a $12.2 million tax benefit on the remeasurement of uncertain tax positions due to the movement in foreign currency exchange rates. The expense in the fourth quarter of 2023 reflected the reversal of a previously recorded tax benefit earlier in 2023.

Operational Highlights

The Company’s rigs continued to perform well, with six rigs achieving revenue efficiency of over 96% for the first quarter, with overall revenue efficiency for the quarter of 94% excluding the Ocean GreatWhite incident. The Ocean Courage and Ocean BlackHawk operated for the full quarter under new contracts, and the Ocean Patriot completed its campaign with Repsol and began its two-well P&A contract with Serica. The Ocean GreatWhite safely recovered the LMRP from the seabed and arrived in the Kishorn port on March 15 for repairs. The repairs are progressing well, and the rig is currently scheduled to be back on the well location in the first half of June, in-line with prior estimates.

Wolford concluded, “Looking ahead, we are focused on the Ocean GreatWhite returning to work safely, securing additional backlog for our rigs, and delivering operational excellence across the fleet to maximize our cash flow generation.”

Non-GAAP Financial Measures (Unaudited)

To supplement the Company’s unaudited condensed consolidated financial statements presented on a basis in conformity with generally accepted accounting principles in the United States (GAAP), this press release provides investors with adjusted earnings before interest, taxes, depreciation and amortization and uninsured costs for repairs to the Ocean GreatWhite, which we consider to be outside the normal course of our operations (or Adjusted EBITDA), which is a non-GAAP financial measure. Management believes that this measure provides meaningful information about the Company’s performance by excluding certain items that may not be indicative of the Company’s ongoing operating results. This allows investors and others to better compare the Company’s financial results across previous and subsequent accounting periods and to those of peer companies and to better understand the long-term performance of the Company. Non-GAAP financial measures should be considered a supplement to, and not as a substitute for, or superior to, contract drilling revenue, contract drilling expense, operating income or loss, cash flows from operations or other measures of financial performance prepared in accordance with GAAP.
