"After two decades in this industry, I can say without a doubt that it is the people who make it special," Swinney wrote.

Swinney's distribution career included ProBuild before he co-founded Kodiak Building Partners, which he led for 15 years. Following QXO's April 1 acquisition of Kodiak, Swinney became leader of QXO s newly created LBM division.

The Kodiak transaction marked QXO's entry into lumber and broadened its reach across major building-product categories. At closing, QXO said the acquisition expanded its addressable market to more than $200 billion.

Swinney called the deal a definitive capstone for Kodiak. In announcing his departure, Swinney highlighted Kodiak's locally led operating model and said he was particularly proud of building a company centered on entrepreneurship, collaboration and empowering employees closest to customers and their communities.

He did not identify another business role or company he plans to join. Instead, Swinney said his next chapter will include spending more time with his family and working to support principles he believes encourage entrepreneurship and business creation.

 His exit comes as QXO continues integrating a series of major acquisitions and reshaping its leadership structure. The company recently named longtime Honeywell executive Ken West president and chief operating officer, effective Sept. 1, with responsibility for day-to-day operations and integration efforts involving Kodiak and TopBuild. 

QXO acquired Kodiak from Court Square Capital Partners for approximately $2.25 billion on April 1. The company has said the transaction is part of its broader strategy to build a technology-enabled building products distribution platform targeting $50 billion in annual revenue.
