HOUSTON, June 20, 2023 /PRNewswire/ -- Drilling Tools International Holdings, Inc., a leading oilfield services company that manufactures and provides a differentiated, rental-focused offering of tools for use in horizontal and directional drilling, announced today that it completed its business combination with ROC Energy Acquisition Corp.

"We close this transaction in a strong strategic position, with zero debt and poised to execute on a pipeline of growth opportunities within our core competency. We could not have reached this point without the dedication and support of our employees, customers and partners, for whom we are grateful. Thank you all."

Daniel Kimes, Chief Executive Officer of ROC added, "The merger between ROC and DTI is the culmination of an incredible amount of work and trust between both parties. We share the belief that it is a very advantageous time to go public. Secular trends in the energy industry point towards increased activity levels across the globe, which will help drive organic growth for DTI. Further, the oilfield services sector is ripe for consolidation, which will spur inorganic growth through M&A. DTI has the balance sheet and the distribution network to make it a natural acquiror in the sector. Finally, the shared vision, industry dynamics and trust in management is why we've committed significant PIPE capital in support of the Company."

Transaction Overview
The transaction generated $25.9 million of cash from a common stock PIPE and $1.7 million of cash from ROC's trust account, after giving effect to shareholder redemptions. In addition, existing DTI shareholders elected to reinvest $10.8 million of the cash they were to receive in the merger into the common stock PIPE, and affiliates of ROC's sponsor reinvested the $4.1 million owed to them under convertible promissory notes into the common stock PIPE.
