CFO Outlook Commentary

We expect first quarter 2022 total revenue to be in the range of $27-29 billion, which represents 3-11% year-over-year growth. We expect our year-over-year growth in the first quarter to be impacted by headwinds to both impression and price growth.

• On the impressions side, we expect continued headwinds from both increased competition for people’s time and a shift of engagement within our apps towards video surfaces like Reels, which monetize at lower rates than Feed and Stories.
• On the pricing side, we expect growth to be negatively impacted by a few factors:
  • First, we will lap a period in which Apple’s iOS changes were not in effect and we anticipate modestly increasing ad targeting and measurement headwinds from platform and regulatory changes.
  • Second, we will lap a period of strong demand in the prior year and we’re hearing from advertisers that macroeconomic challenges like cost inflation and supply chain disruptions are impacting advertiser budgets.
  • Finally, based on current exchange rates, we expect foreign currency to be a headwind to year-over-year growth.

In addition, as  previously noted, we also continue to monitor developments regarding the viability of transatlantic data transfers and their potential impact on our European operations.

We expect 2022 total expenses to be in the range of $90-95 billion, updated from our prior outlook of $91-97 billion. Our anticipated expense growth is driven by investments in technical and product talent and infrastructure-related costs.

We expect 2022 capital expenditures, including principal payments on finance leases, to be in the range of $29-34 billion, unchanged from our prior estimate. Our planned capital expenditures are primarily driven by investments in data centers, servers, network infrastructure, and office facilities. As we discussed previously, this range reflects a significant increase in our  artificial intelligence and machine learning  investments, which will support a number of areas across our Family of Apps. While our Reality Labs products and services may  require more infrastructure capacity in the future, they do not require substantial capacity today and, as a result, are not a significant  driver of 2022 capital expenditures.

Absent any changes to U.S. tax law, we expect our full-year 2022 tax rate to be similar to the full-year 2021 rate.

Ticker Symbol Change to META

Meta’s Class A common stock is expected to begin trading on NASDAQ under the ticker symbol ‘META’ in the first half of 2022. This will replace the current ticker symbol ‘FB,’ which has been used since the company’s initial public offering in 2012, and more details on exact timing will be forthcoming. No action is required by our stockholders with respect to the ticker symbol change and it does not affect the rights of our stockholders. Our Class A common stock will continue to be listed on NASDAQ and the CUSIP number will remain unchanged.
