What Happened
Natural Gas Services Group, Inc. (NGS) filed a Form 8‑K reporting that on July 9, 2026 Ham, Langston & Brezina, L.L.P. (HL&B) resigned as the company’s independent registered public accounting firm after CohnReznick LLP acquired certain HL&B assets.

• Cause: HL&B completed a transaction in which CohnReznick acquired certain HL&B assets.
• Prior audits: HL&B’s audit reports for years ended Dec. 31, 2025 and 2024 were unmodified (no adverse opinion, disclaimer, or qualification).
• Disagreements/reportable events: None reported for 2025, 2024, or the interim period through July 9, 2026.
• Exhibit filed: Letter from HL&B to the SEC dated July 10, 2026 (Exhibit 16.1).

Why It Matters
A change in independent auditor is a material corporate event investors track because it affects audit continuity and oversight of financial reporting. In this case the change appears to be driven by a professional-services transaction (asset acquisition) rather than a dispute: prior audits were clean and no disagreements or reportable events were disclosed. Investors should note the new auditor (CohnReznick) will handle the audit for the remainder of 2026 and monitor future filings for any audit-related disclosures or changes.
