We chat with John Gunderson, who authored our three-part analysis series and subsequent case study report on Wesco’s recent and ongoing transformation as North America’s top electrical distributor.
Wesco International stands atop MDM’s Top Electrical, Data and Security products distributors list via its more than 22 billion dollars in annual revenue.
To get there, the Pittsburgh-headquartered company underwent one of the biggest transformations we’ve seen from a major distributor over the past decade.
Wesco’s $4.5 billion acquisition of Anixter International in 2020 was a landmark transaction in the electrical supply space, combining two distributors that each had about $8 billion in revenue at that point.
So, it essentially doubled the size of Wesco and led to a multi-year integration project. Along the way, the company has enacted various digital, business model and talent innovations to continue transforming the company.
All of this activity was recently analyzed in a three-part article series and subsequent case study report by John Gunderson, who writes and speaks on the B2B distribution channel. He previously spent 20 at several different distributors in roles of marketing, sales and category management, including two-and-a-half years at Anixter.
