Meta Q3 2026 Earnings Preview: Operating Margin, Not Revenue, Decides the Quarter

What the street expects

Meta Platforms reports results for the September 2026 quarter after the market closes on Wednesday, 21 October 2026. Consensus expects earnings per share of $6.59 on revenue of $63.31 billion. The table compares that with the same quarter a year earlier.

The revenue change is simple arithmetic on the two figures. The EPS line is not comparable: the 2025 figure was held down by an income tax expense of $18.95 billion on $21.66 billion of pre-tax income in the filed statements, so a year-on-year EPS change would mostly measure that item rather than the business.

Coverage over the past week has centred on Meta's push to sell its AI tools to enterprise customers, a theme investors will want to hear about on the call. The headlines are a guide to what the market is watching, not a change to the consensus numbers.

The track record

Revenue has beaten consensus in each of the last four quarters, by between 1.0% and 3.5%. The third quarter of 2025 came in at $51.24 billion against $49.51 billion expected. The second quarter of 2026 came in at $60.80 billion against $60.22 billion. Revenue growth in the filed statements was about 26% in the third quarter of 2025, 24% in the fourth, 33% in the first quarter of 2026 and 28% in the second. Those are steady growth rates, not a slowdown.

EPS is harder to read. Meta beat in two of the last four quarters and missed in two. The misses were the third quarter of 2025, at $1.05 against $6.72 expected, and the second quarter of 2026, at $6.18 against $7.19. The beats were the fourth quarter of 2025, at $8.88 against $8.19, and the first quarter of 2026, at $10.44 against $6.70. The first-quarter beat included an income tax benefit of $5.02 billion in the filed statements. On this record, the EPS line says more about tax items than about operations.

The line that decides the quarter

Revenue is not the open question. Four straight beats and a consensus that assumes roughly 24% growth say the top line is running ahead of expectations. The question is cost. In the second quarter of 2026, operating income was $18.78 billion on revenue of $60.80 billion, an operating margin of 30.9%. In the first quarter the margin was 40.6%, and in the third quarter of 2025 it was 40.1%. Research and development expense rose to $21.66 billion in the second quarter, or 35.6% of revenue, from $12.94 billion, or 27.2% of revenue, a year earlier. All percentages are arithmetic on the filed figures.

The line that decides the quarter is therefore whether margin recovers from 30.9%. If research spending keeps growing faster than revenue, a revenue beat will still leave margin as the story. A margin back in the 40% range would suggest the second-quarter step-down was temporary; a figure close to 31% would suggest it is the new level. The filing will settle which.

Valuation and the Maz Rating

At the latest quote of $736.72, Meta has a market capitalisation of $1.88 trillion and trades about 5.5% below its 52-week high of $779.82. Its trailing earnings yield of 3.6% implies a price-to-earnings ratio of about 27.5 (arithmetic). The analyst price-target consensus is $802.80, within a range of $595 to $1,000.

Meta's Maz Rating is 4.71 out of 5 (Strong Buy). Profitability (4.99), Momentum (4.32) and Financial Health (4.18) are the strongest of the five factors, and Growth scores 3.98. Valuation scores 1.39, the weakest factor, which is consistent with the earnings multiple above.

Bottom line

Revenue has beaten for four quarters and consensus assumes that growth continues. The quarter will be judged on operating margin rather than the top line. Because reported EPS has been moved by tax items in both directions, the margin and research-spending lines in the filing are the more useful guide.
