Intel CEO, Brian KrzanichIntel

Intel said on Thursdaythat Brian Krzanich stepped down as the company’s CEO and is no longer on the board of directors. The reason for the immediate departure is a “consensual” relationship with an employee, violating Intel’s policy of keeping your hands to yourself. Filling his shoes for the interim will be chief financial officer Robert Swan.

“Intel was recently informed that Mr. Krzanich had a past consensual relationship with an Intel employee,” the company said. “An ongoing investigation by internal and external counsel has confirmed a violation of Intel’s non-fraternization policy, which applies to all managers. Given the expectation that all employees will respect Intel’s values and adhere to the company’s code of conduct, the board has accepted Mr. Krzanich’s resignation.”

While the board hires an executive search firm to find a proper replacement, Swan will take the Intel wheel by working closely with the senior leadership team to manage operations. His past experience includes serving as CEO of Webvan Group Inc., nine years as CFO at eBay, CFO of Electronic Data Systems, and more. His current CFO role at Intel — aside from filling Krzanich’s shoes — includes leading the company’s global finance, IT, and corporate strategy organizations.

Intel’s board says it has “a robust succession planning process in place” and will seek out a new, permanent CEO from candidates within and outside the company.

Krzanich, 58, joined Intel as an engineer in 1982. By January 2012, he moved to the role of chief operating officer and helped bring Intel’s products to China. Then in May 2013 he was promoted once again to the role of CEO where he led the company on different paths outside its main processor focus, such as wearables, artificial intelligence, and cloud computing.

Krzanichcame under fire earlier this year for dumping around $11 millionworthof Intel stock prior to revealing theSpectreand Meltdown flaws in its processors. He made the sale in November as Intel and manufacturers worked to create patches before the problems were publicly exposed.DefendingKrzanich, Intelindicatedthe sale wasunrelatedto theSpectreand Meltdown announcement despite share valuetakinga hit afterKrzanichrevealed the flaws.

The sudden resignation is surprising and likely a jolt to the company. Non-fraternization policies are common in businesses, as employers dictate that you can’t mix business with pleasure. ButKrzanich’s resignation is a prime example that even the CEO of a company can’t avoid a non-fraternization policy — at least, not at Intel. Speculation indicates thatIntel’s boarddidn’t look the other way due to not wanting additional drama outside the ongoingSpectre/Meltdown fiasco.
