Vertical market focus resulted in $3.05 billion in annual recurring revenue (ARR) for the top 100 managed service providers serving specific industries, up roughly 42% from last year’s research.

The list, developed by SC Media sister brand ChannelE2E, reflects larger-than-usual boost likely caused by the U.S. economy, which experienced accelerated IT spending in 2021 versus 2020 as businesses adjusted to the “new extended normal” of COVID-19.

The largest slice of vertical revenue came from healthcare (18%), manufacturing (14%) and financial services/banking (13%), with manufacturing seeing a 5 point increase compared with a year ago as customers sought support in efforts to navigate supply chain and cybersecurity business pressures.

Forty-nine of this year’s Top 100 companies also appeared on last year’s list. That’s lower than last year’s repeat count of 59. The dip in repeat honorees reflects a larger base of MSPs participating in the survey, coupled with previous honorees that have been acquired. And merger and acquisition deals – often backed by private equity firms – continued to unite several vertical market MSPs.
