Exhibit 99.2

As you may have seen in Patterson-UTI’s press release today, we announced that we have entered into a definitive agreement to acquire Ulterra Drilling Technologies, L.P. (“Ulterra”), a global provider of specialized drill bit solutions.

The addition of Ulterra to our drilling offering and our recent announcement to merge with NexTier Oilfield Solutions advances our strategy to enhance our positions in both drilling and completions, areas where Patterson-UTI has a strong 45-year history of operations and innovation.

Founded in 2005 and headquartered in Fort Worth, Texas, Ulterra designs, manufactures, sells and rents PDC drill bits. With a global footprint, Ulterra supports customers in over 30 countries with sales, manufacturing, and repair facilities throughout North and South America, the Middle East, and Asia. In North America, Ulterra is the leading provider of PDC drill bits, with operations across the most active basins in the United States and Canada. We are excited about the potential to add Ulterra’s leading drill bit technologies to better support our customers’ efforts to drill better wells.

Ulterra’s industry leading position in the North American PDC drill bit market will expand our operational and technology portfolio and strengthen our position as a leading drilling and completions company. Ulterra’s growing Middle East presence will also broaden our geographic footprint and provide strong relationships with key customers in this international market.

In addition, Ulterra’s proprietary BitHub^™ data platform is complementary to our PTEN+ data platform and will expand our comprehensive data analytics capabilities from the drill bit to the well completion. When you consider the combination of data systems from Patterson-UTI, NexTier and Ulterra, we believe we will have one of the most comprehensive data analytics capabilities for drilling and completions across the United States, which can allow us to better support our customers’ objectives to improve well productivity.

We anticipate closing of the Ulterra acquisition to occur in the third quarter of 2023. After closing, Ulterra will be a Patterson-UTI company and continue to operate under the Ulterra name. John Clunan, current President and CEO of Ulterra, will continue to lead Ulterra and will report to Mike Holcomb. Ulterra’s headquarters will remain in Fort Worth, Texas.

Both Patterson-UTI and Ulterra share a culture of innovation and a focus on superior service quality, while building deep and highly collaborative relationships with customers. We are very excited about this opportunity to strengthen our drilling offering and grow our overall business with such a well-respected company. We look forward to welcoming the entire Ulterra team to Patterson-UTI.
