Scott Matlock, a long-time deal maker at Morgan Stanley who has been responsible for its mergers and acquisitions business in Europe and Asia, is leaving the firm, according to an internal announcement last week.

Matlock, a 25-year veteran of Morgan Stanley, has informed the bank that he will retire, according to a memo reviewed by MoneyBeat that was sent around Friday by Morgan Stanley investment banking executives Mark Eichorn and Franck Petitgas. Matlock, a specialist in the media and telecommunications sectors, hasn't decided what his next move will be, people familiar with the matter said.
