NBC’s Lester Holt is out at Nightly News, the flagship show he has hosted for nearly a decade.

Holt, 65, announced he is stepping down in a memo sent to staffers Monday, ten years after he stepped in to replace longtime fixture Brian Williams on a full-time basis.

The veteran anchor will now only man his usual spot on Dateline, NBC News’ Executive Vice President of Programming Janelle Rodriguez said in a statement.

NBC – whose asset MSNBC just cancelled Joy Reid’s show The ReidOut – have yet to announce a replacement.

‘[Holt] will continue at the helm of Nightly until early summer,’ Rodriguez said, revealing how the anchor will then devote ‘his energy to the rapidly-expanding powerhouse that is Dateline.’

Holt – previously the host of the show’s weekend edition – began hosting Nightly News on weekdays in June of 2015, after a scandal surrounding reporting from the Iraq War upended Williams’ career.

He has since told staffers his time on the show was an ‘amazing ride’ –  doing so in a letter sent to Nightly and Dateline staffers Monday morning.

The principal anchor of ‘Dateline’ since September 2011 did not mention the show’s waning ratings, which are down year-over-year.

Instead, he expressed excitement about ‘continuing as anchor of “Dateline NBC” for the first time ‘in a full time capacity’.
