Wall Street has been promised a more svelte Warner Bros. Discovery, which is staring down a recession with about $55 billion in debt, and C.E.O. David Zaslav is moving aggressively to trim the fat. Zaz and his ax man, C.F.O. Gunnar Wiedenfels, have been unflinching in their drive to “identify synergies” which seems to be all the more pressing after J.P. Morgan downgraded the WBD stock earlier this week, sending it down to around $14 a share. The cuts started, of course, with the infamous decision to kill CNN+ before it ever really got a chance to prove itself, and were soon followed by cuts to scripted programming at TNT and TBS, and, most recently, about 30 percent of the ad sales staff, or nearly 1,000 jobs.
