Starting Dec. 19, CNBC will revamp its morning lineup around an extended “Squawk Box.” Carl Quintanilla will return as a member of the reconfigured anchor team that will preside over the 6-9 a.m. portion of “Squawk,” joined by Joe Kernen and Becky Quick. Mark Haines moves to a new set at the New York Stock Exchange to anchor the fourth hour of the signature show.

Leaving the lineup will be “Wake-Up Call,” which will be replaced by a live 4-6 a.m. global business show still to be named.

“Squawk” veteran David Faber will contribute to the fourth hour of the morning show, and will appear throughout the day.

Mr. Quintanilla is a former Wall Street Journal reporter who has successfully made the transition to TV after joining CNBC full time in 1999. He has been on the fast track as a correspondent for NBC News for the past three years.

Also joining the “Squawk” block will be Charles Gasparino, who until recently was a senior writer for Newsweek.

CNBC President Mark Hoffman said in Tuesday’s announcement that the reconfigured lineup will translate into “a substantive and entertaining way to start the business day.”
