U.S. boardrooms are rapidly dropping diversity rules. HR can’t ignore the fallout

Six companies — AMD, Capital One, Microsoft, Starbucks, Uber and Wells Fargo — had gone even further, extending similar diversity language to CEO succession planning specifically. All but Microsoft have since walked that back, according to the ESGAUGE data.

For governance watchers, this is a story about proxy statements and shareholder pressure. For HR leaders, it’s a story about something closer to home: the talent pipeline, succession planning and the credibility gap that can open up when a company’s public commitments and its internal practice drift apart.

The numbers behind the retreat

The pullback isn’t limited to board nomination language. According to Spencer Stuart’s 2026 U.S. Board Index, the share of S&P 500 boards using Rooney Rule-type provisions — policies modeled on the NFL rule requiring at least one Black candidate to be interviewed for head-coaching vacancies — fell to just 12% this year, down from 58% just a year earlier, before the current Trump administration took office.

At the same time, boards are increasingly filling seats with former chief executives, a pool still dominated by white men. Former CEOs made up 37% of new S&P 500 directors this year, the highest share since a 42% peak in 2012, Spencer Stuart found, while Reuters reporting on the same index noted that Black directors accounted for just 4% of new appointments, down from double that a decade ago.

“Now the bro culture is alive and well,” Nia Impact Capital chief investment officer Kristin Hull told Reuters.
