Currently privately held.

Core Business

Ahlstrom is the world's most focused pure-play specialty functional materials manufacturer, having strategically divested all non-core operations (including its abrasives business in 2025) to concentrate on high-value fiber-based solutions. The company maintains global #1 or #2 positions in filtration media, release liners, food packaging papers, medical fabrics, laboratory and life science materials, and masking/packaging tapes. Ahlstrom's R&D portfolio of 500+ active patents drives the development of sustainable fiber-based alternatives to plastics and synthetic materials, with 90%+ of raw materials being renewable fibers. The company achieved a record-high 18.8% EBITDA margin in 2025 despite challenging macroeconomic conditions.

Global Presence

Operating 37 production facilities across 13 countries in Europe, the Americas, and Asia-Pacific, Ahlstrom maintains a strategically distributed manufacturing footprint that enables localized supply to customers in over 100 countries. In 2025, the company completed the acquisition of Stevens Point (USA) smart food packaging operations and the EBF life sciences laboratory filtration paper business, expanding its North American specialty paper capacity. Ahlstrom earned EcoVadis Platinum rating and CDP Climate Leadership A- rating, with "innovation products" representing 33% of total sales — demonstrating the successful translation of R&D into commercial revenue.

Key Strengths

Ahlstrom's global #1 or #2 market positions in filtration media, release liners, and multiple specialty paper segments create pricing power and customer stickiness that commodity paper producers cannot achieve. The company's deep R&D capabilities with 500+ active patents drive sustainable fiber-based alternatives to plastics — a secular growth opportunity. Record-high profitability with 18.8% EBITDA margin reflects disciplined pricing, cost optimization, and the value of pure-play specialization. EcoVadis Platinum and CDP A- ratings, combined with 90%+ renewable raw materials, position Ahlstrom as the sustainability leader in specialty papers. VerityRank Score of 89/100.
