Previewing Q3 Earnings: What Can Investors Expect?

S&P 500 Q3 2025 earnings are projected to grow +5.1% on +6% revenue, marking the slowest pace since 2023 Q3, following stronger growth in prior 2025 quarters. Despite this deceleration, aggregate estimate revisions have been positive since late April, primarily driven by the Tech and Finance sectors, which collectively account for over 50% of index earnings. The Tech sector remains a critical growth driver, expected to see +11.9% earnings growth, without which the S&P 500's overall Q3 growth would be significantly lower at +2%. Early indicators for the Tech sector include upcoming earnings from Oracle and Adobe, while calendar year S&P 500 EPS are estimated at $258.50 for 2025 and $290.59 for 2026.

Analysis

The S&P 500 is projected to experience a significant earnings growth deceleration in Q3 2025, with expectations at +5.1%, a stark slowdown from the approximately +12% growth rates in the preceding two quarters and the lowest pace since Q3 2023. Despite this headline deceleration, the aggregate estimate revision trend has been positive since late April, but this improvement is highly concentrated. The positive revisions are almost entirely driven by the Technology and Finance sectors, which together account for over 50% of the index's total earnings and are offsetting negative revisions in 11 of the 16 Zacks sectors, including Medical, Transportation, and Consumer Staples. The Technology sector is the critical driver, with its earnings forecast to grow +11.9%; excluding its contribution, the S&P 500's Q3 earnings growth would fall to just +2%. Upcoming earnings from Oracle and Adobe will serve as early bellwethers for these high-stakes tech expectations. The market is already showing clear differentiation within the sector, rewarding Oracle for its AI strategy while expressing concern that AI could dilute Adobe's competitive position, as reflected in their diverging stock performance and estimate trends.

Key Decisions for Investors

• Given that projected S&P 500 earnings growth is critically dependent on the outperformance of the Technology and Finance sectors, investors should assess their portfolio for concentration risk, as the headline +5.1% growth figure masks underlying weakness across a majority of other sectors.
• Closely monitor the upcoming earnings reports from Oracle and Adobe, as these will provide a crucial early test of the bullish Tech sector thesis that is currently supporting the entire market's earnings forecast.
• When evaluating technology investments, it is vital to scrutinize company-specific AI strategies and competitive moats, as the market is actively differentiating between perceived AI winners like Oracle and potential victims like Adobe.
