Methodology:

To determine America’s most and least reputable companies, 24/7 Wall St. reviewed reputation scores of the nation’s 100 most recognizable companies from the 2020 Harris Poll Reputation Quotient (RQ), produced by market research firm Harris Insights and Analytics. 

The study consists of two parts: a nominations stage, in which consumers identify the nation’s most visible companies, followed by a ratings stage, in which each company’s reputation is measured on a scale of 0-100. The survey was conducted in late June and early July 2020. A full methodology can be found here. 

Additional company information came from SEC filings and other publicly available documents.
