Meta Platforms Inc said on Wednesday it would cut more than 11,000 jobs, or 13% of its workforce, as the Facebook parent doubled down on its risky metaverse bet amid a crumbling advertising market and decades-high inflation.

The mass layoffs, one of the biggest this year and the first in Meta's 18-year history, follow thousands of job cuts at other tech companies including Elon Musk-owned Twitter, Microsoft Corp and Snap Inc.

Like its peers, Meta hired aggressively during the pandemic to meet a surge in social media usage by stuck-at-home consumers. But its business has suffered this year as advertisers and consumers pull the plug on spending in the face of soaring cost pressures and rapidly rising interest rates.

"Not only has online commerce returned to prior trends, but the macroeconomic downturn, increased competition, and ads signal loss have caused our revenue to be much lower than I'd expected," Chief Executive Officer Mark Zuckerberg said in a message to employees.

"I got this wrong, and I take responsibility for that."

Meta, once worth more than a trillion dollars, is now valued at $256 billion after losing more than 70% of its value this year alone.

Shares rose 4% on Wednesday as investors cheered caution by a company that has been pinning its future on the metaverse with pricey investments that Zuckerberg himself says will take a decade to bear fruit.

"The market is breathing a sigh of relief that Meta's management or Zuckerberg specifically seems to be heeding some advice, which is you need to take some of the steam out of the growing expenditure bill," Hargreaves Lansdown analyst Sophie Lund-Yates said.

The company now expects 2023 expenses between $94 billion and $100 billion, compared with the $96 billion to $101 billion range projected previously. It also narrowed its 2023 capital expenditures forecast range.

Other than the job cuts, which will impact units across Meta with a disproportional hit to the recruiting and business teams, the company will also reduce office space, lower its discretionary spending and extend a hiring freeze into the first quarter to rein in expenses.
