ROC

Roc Energy Acquisition Corp

A "blank check" company (a special purpose acquisition company, or SPAC) founded in 2021 to raise money and merge with a business in the U.S. oil and gas sector. In June 2023 it completed a business combination with Drilling Tools International, a firm founded in 1984 that manufactures and rents the downhole drilling tools used in horizontal and directional oil and gas drilling — and took on that name, trading under the ticker "DTI." The "ROC" in its name was simply the name chosen for the shell company, not tied to any industry term.

Common stock — Acquired by Drilling Tools International in June 2023
