This is a clean auditor change driven by an acquisition of the prior firm's assets — no red flags. Monitor the next 10-Q for any unexpected audit-related disclosures, but no immediate trading action is warranted.

Executive Summary
Natural Gas Services Group (NGS) filed an 8-K reporting that its independent auditor, Ham, Langston & Brezina (HL&B), resigned after CohnReznick acquired certain HL&B assets.
