All 2018 Big 50 List companies are ranked according to their most recent full-year worldwide sales, and all figures are reported in USD. In some cases,
foreign currency was converted based on exchange rates
at the date that fiscal year ended.
All Big 50 companies are based in North America. Some
companies are headquartered elsewhere, but for our list,
we only account for their North American operations.
We obtain information for publicly-traded companies
based on their annual and quarterly reports, earning
statements and company verifications. For privately-held companies, we rely on their self-reported data and
follow-up communication. Recently published press
releases, company website information and other news
reports are also used to supplement company data for
our Big 50 feature. The Big 50 interviews were conducted
via email, survey and by phone by Industrial Distribution
We elect to refrain from listing any companies that
don’t fit our criteria of an ‘industrial distributor,’ which
becomes more challenging each year as the market
evolves. Some privately-held distributors elect to not
share their revenue numbers, so for those companies,
we make an educated estimate based on their most
recently shared revenue figures and company news.
There are several companies, including McMaster-Carr,
which we acknowledge would make our Big 50 List, but
haven’t shared their revenue figures in more than five
years, for which we elect to not place them on our list by
We don’t include master distributors on The Big 50.
For those of you who don’t see your company name
on our list, but think you should, please contact us with
your information and we’ll consider adding your company
to our Big 50 pool for 2019. As always, your feedback —
good or bad — is appreciated.
