HYDROFARM HOLDINGS GROUP, INC. 8-K

What Happened

• Hydrofarm Holdings Group, Inc. announced on April 20, 2026 (filing date) that its Audit Committee approved engaging CBIZ CPAs P.C. as the company's independent registered public accounting firm for the fiscal year ending December 31, 2026. The Committee concurrently dismissed Deloitte & Touche LLP as the company's independent registered public accounting firm effective April 14, 2026. The change was not due to any disagreement between Hydrofarm and Deloitte.

Key Details

• Audit Committee approved CBIZ CPAs on April 14, 2026 for the 2026 fiscal year.
• Deloitte was dismissed effective April 14, 2026; its audit reports for years ended Dec. 31, 2025 and 2024 contained no adverse opinions or disclaimers and were not qualified or modified.
• The company reported no “disagreements” or “reportable events” with Deloitte for fiscal years 2025 and 2024 or through April 14, 2026 (per Regulation S-K definitions).
• Hydrofarm and its representatives did not consult CBIZ CPAs on accounting or auditing matters for 2024–2025 or the interim period through April 14, 2026. Deloitte provided a letter agreeing with the 8-K disclosures (filed as Exhibit 16.1).

Why It Matters

• An auditor change is a governance and control event investors watch because it affects future financial statement audits and disclosures. Hydrofarm’s filing states the switch was approved by the Audit Committee and was not driven by any disagreements or reportable events, and that prior Deloitte audits for 2024–2025 were clean. Investors should note the new auditor (CBIZ CPAs) will handle the 2026 audit cycle; any changes in audit approach or timing could affect future reporting but are not described in this filing.
