Affiliated Distributors said its owner-members delivered record performance in 2025, with total member company sales, member purchases from AD supplier partners, and net distributions to its owner-members. rising 20% to $100 billion. The growth was driven by merger activity, acquisitions, and steady same-store growth across North America.
Same-store sales increased 6% for the year, AD said. By country and in local currency, same-store sales rose 6% in the U.S., 5% in Canada and 1% in Mexico.
AD said most of its nonorganic growth stemmed from its merger with IMARK Electrical, which expanded AD’s reach in the electrical distribution channel. The group also reported active consolidation among members, with companies acquiring 62 businesses outside the AD network and 27 businesses within the group during 2025.
Purchases by member companies from AD supplier partners increased 34% for the year and were up 7% on a same-store basis, indicating higher purchasing volumes through AD’s supplier programs even after adjusting for acquisition activity.
Net distributions to AD’s owner-members exceeded $1.8 billion, another record for the group.
“2025 was a very strong year for AD and its owner-members, marked by record results and incredible growth,” CEO Bill Weisberg said in a statement. “2026 is already on track to be another record year due to our merger with the great companies of The Commonwealth Group and positive early indicators in most of our industries.”
AD has continued to expand its footprint through major combinations. The merger with IMARK Electrical was finalized in September 2024. AD also announced plans to merge with The Commonwealth Group, with that transaction expected to be operationally effective Jan. 1.
The results reflect the growing role buying groups play in wholesale distribution consolidation, as independent distributors expand through acquisitions and translate greater scale into increased purchasing leverage with preferred suppliers and higher distributions back to members.
