Why Meta Platforms looks undervalued

Meta Platforms' free cash flow was negative in the third quarter of 2026, and the company said it expects to continue investing aggressively beyond 2026. At $648.85 the stock looks cheap, provided its capital expenditure falls as a share of revenue by 2028 and its advertising keeps growing.

In that quarter Meta generated $32.79 billion of cash from operating activities and spent $34.91 billion on capital expenditures, including principal payments on finance leases, so its free cash flow was negative $2.12 billion. It narrowed its 2026 capital expenditure outlook to a range of $135 billion to $145 billion and has given no figure for 2027.

Meta's advertising kept growing in the third quarter of 2026, when its advertising revenue was $63,061 million, up 26% from a year earlier.

Meta's margin fell in its Family of Apps segment, whose operating margin was 27% in the third quarter of 2026 against 49% a year earlier, a quarter that included a $9.89 billion charge for the agreement with state attorneys general. Excluding that charge, Meta still expects its 2026 operating income to be above its 2025 operating income.

Meta's Reality Labs segment lost $4,129 million in the third quarter of 2026, against $4,432 million a year earlier, and Meta now expects its Reality Labs losses for 2026 to be in a range of $18 billion to $19 billion.

“Separately, we remain focused on improving Reality Labs profitability and expect losses to narrow next year to around $15 billion as we reallocate investment toward other priority areas, primarily AI.”

Meta Platforms press release on its third quarter 2026 results, October 21, 2026

The model assumes that Meta's revenue grows 28.0% in 2026, 22.0% in 2027 and 19.0% in 2028, against the analysts' consensus of 27.4%, 21.4% and 18.7%. It raises the EBITDA margin from 46.0% in 2026 to 49.0% in 2028 and sets capital expenditure at 50.0% of revenue in 2026 and 2027 and 45.0% in 2028. Valued at 16.1 times its 2028 EBITDA, Meta reaches $1,124 a share by 2028, about 73% above the share price at the model's date.
