Mativ Holdings, Inc. 8-K

What Happened
Mativ Holdings, Inc. (MATV) filed an 8-K on May 6, 2026, disclosing that effective January 1, 2026 it changed its primary GAAP performance metric from Operating Profit to Gross Profit. The company also revised how it allocates Selling & General (SG&A) expenses between its operating segments and Unallocated items, moving certain IT infrastructure and shared service costs into the segments when applicable. The filing includes Exhibit 99.1 and provides supplemental 2025 segment reconciliations of Gross Profit to Adjusted EBITDA for its two reportable segments: Filtration & Advanced Materials (FAM) and Sustainable and Adhesive Solutions (SAS).

Key Details

• Effective date of change: January 1, 2026; 8-K filed May 6, 2026.
• Primary metric changed: from Operating Profit → Gross Profit.
• SG&A allocation change: IT infrastructure and certain shared service costs will now be allocated to operating segments rather than presented in Unallocated.
• Supplemental disclosures: reconciliations for 2025 of Gross Profit to Adjusted EBITDA for FAM and SAS; non-GAAP adjustments exclude restructuring, impairment, purchase accounting adjustments, acquisition/integration costs, stock-based compensation, and depreciation & amortization.
• The supplemental information supersedes previously disclosed historical financial information and is not presented as Article 11 pro forma financials under Regulation S‑X.

Why It Matters
For investors, this is a reporting and presentation change that can affect how segment profitability and comparable trends are shown (Gross Profit and segment Adjusted EBITDA may differ from prior presentations). The SG&A allocation shift may change reported segment margins by assigning more shared costs to segments instead of Unallocated. Management says the new measures reflect how it evaluates operations, and the company provided reconciliations for 2025 to help investors compare results under the new presentation.
