Cisco Systems, Inc. (NASDAQ:CSCO) CEO John Chambers will step down.

The company announced on Monday that the boss will be departing once his board term runs out in December. Current CEO Chuck Robbins will take over as Cisco chairman.

Robbins has been the CEO for two years now, following Chambers’ decision to step down from the role but remain as chairman of the board. Chambers led the company as CEO from 1995 to 2015, following his 1991 appointment as the head of sales.

“It is time for Cisco to move on to its next generation of leadership including at the board and Chairman level and to position this seamlessly for the future,” Chambers wrote. “It is also time for me to move on to the next chapter of my life, on both a personal and business level.”

When Chambers first took over at Cisco, the company’s annual revenue was $1.2 billion, and that figure reached $50 billion at the end of his tenure. The news has not garnered a lot of attention from shareholders and analysts due to the fact that Robbins has essentially been in charge for two years.

Some people believe that Chambers may one day run for office despite the fact that is a self-proclaimed “moderate Republican,” which he considers to be an “endangered species” in the country’s current political climate.

CSCO shares grew 0.6% Monday.
