HYFM · Hydrofarm Holdings Group, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“These conditions and events, considered in the aggregate, raise substantial doubt about the Company's ability to continue as a going concern. Management's plans to address these conditions include reducing costs through restructuring and other initiatives, including facility consolidations, headcount reductions, focusing on our proprietary brand offerings and expanding and optimizing our logistics business. To improve liquidity the Company is negotiating with lenders and key vendors, and is pursuing additional financing or strategic alternatives including through an offering of equity securities, the sale of assets or businesses, including the sale of Aurora Peat Products ULC ("APP"). Refer to Note 17 – Subsequent Events for further details. Excluding the sale of APP, these plans are not within the Company's control, and therefore cannot be deemed probable. As a result, the Company has concluded that management's plans do not alleviate substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Aug 14, 2026

Shares are restated onto today's split basis. Change compares each row with the same holder's previous filing in the same source; a dash means there is none to compare. Nested 13D/G, insider and fund rows are not summed, since a 13F report already holds them.
