Amazon is laying off another 9,000 employees — read the email CEO Andy Jassy sent to staff

• Amazon is laying off another 9,000 employees.

• That's on top of the 18,000 job cuts announced earlier this year.

• CEO Andy Jassy said the additional cuts weren't announced until cost-cutting analysis was finished.

Amazon is laying off an additional 9,000 employees, the e-commerce giant's CEO Andy Jassy said Monday.

The layoffs will come on top of the cuts to 18,000 positions that the company disclosed in January.

"Some may ask why we didn't announce these role reductions with the ones we announced a couple months ago," Jassy wrote in a memo to staff. "The short answer is that not all of the teams were done with their analyses in the late fall; and rather than rush through these assessments without the appropriate diligence, we chose to share these decisions as we've made them so people had the information as soon as possible. The same is true for this note as the impacted teams are not yet finished making final decisions on precisely which roles will be impacted."

The company is planning to make the additional cuts "in the next few weeks," Jassy wrote in the statement, which noted that the layoffs would affect employees including in Amazon Web Services, the live-streaming platform Twitch, and advertising.

"The overriding tenet of our annual planning this year was to be leaner while doing so in a way that enables us to still invest robustly in the key long-term customer experiences that we believe can meaningfully improve customers' lives and Amazon as a whole," Jassy wrote.

The company is still deciding who exactly will be affected by the layoffs, and expects to finalize those details by late April, providing severance and other benefits to those affected, he wrote.

"We will, of course, support those we have to let go, and will provide packages that include a separation payment, transitional health insurance benefits, and external job placement support," he said.

Jassy said that Amazon was making the cuts amid its evaluation of its operating plan, saying its own internal scrutiny prompted "re-prioritization decisions that sometimes led to role reductions," or to employees being moved to other projects.

It also "led to new openings where we don't have the right skills match from our existing team members," Jassy wrote. The company is planning to conduct "limited hiring" in areas it is focusing on, he said.

The latest round of cuts at Amazon follows Mark Zuckerberg's own disclosure last week about more layoffs at his social media and tech company. Like Zuckerberg, Meta's chief executive, who'd warned of a "new economic reality" in the foreseeable future, Jassy's statement on Monday also pointed to "the uncertain economy" as a factor behind the cuts "to be more streamlined in our costs and headcount."
