Chartwell Advises MacArthur on Acquisition of AMS

May 2023

Chartwell is pleased to announce MacArthur Co. has acquired American Metals Supply Co. (AMS), a leading wholesale distributor of sheet and coil steel, prefabricated duct and fittings, and a complete line of HVAC products. Combined, MacArthur and AMS will service the western two-thirds of the U.S. and be one of the largest distributors of HVAC and related products.

Chartwell advised MacArthur’s board of directors on investment considerations and purchase price as well as financing needs to fund the acquisition and the ongoing working capital requirements of the combined companies. Chartwell managed the due diligence process and effectively negotiated deal terms and conditions opposite AMS’s financial advisors to successfully close the transaction.


“Chartwell has been a trusted advisor to MacArthur for almost 20 years and has advised us in completing a number of strategic acquisitions. The purchase of AMS is yet another reason why we are so very fortunate to have Chartwell’s expert advice. Chartwell’s experience negotiating transactions, combined with their in-depth understanding of our unique business needs, make them the ideal partner for MacArthur and our employees.”

– Barrett Moen, CEO, MacArthur Co.
