5 July 2023business combination● NeutralMajor

On July 3, 2023, Patterson-UTI agreed to buy Ulterra (Ulterra Drilling Technologies, via BEP Diamond Holdings Corp.) for 34,900,000 new Patterson-UTI shares plus $370 million cash, subject to adjustments. If Patterson-UTI's 30-day average share price before closing is under $10.90, the seller could get up to $14,025,000 more based on Ulterra's 2024 performance. The seller also agreed to vote its new shares to help the NexTier merger pass, with a lockup on selling them. Closing needs antitrust clearance and Nasdaq listing, with an October 31, 2023 termination date; this adds more new shares on top of the NexTier deal.

On June 14, 2023, Patterson-UTI agreed to acquire NexTier Oilfield Solutions in an all-stock deal: each NexTier share converts to 0.7520 Patterson-UTI shares. The combined board would have 11 members (six from Patterson-UTI, five from NexTier), and Patterson-UTI plans to double authorized shares from 400 million to 800 million. Closing needs both companies' shareholder approvals, antitrust clearance, Nasdaq listing and an effective S-4, with an outside date of March 14, 2024 (extendable 90 days for regulatory clearances); termination fees are $72.98 million payable by Patterson-UTI or $60.875 million by NexTier in specified cases. This is a new major deal that will issue many new shares to existing holders.
