S&P 500 Posts Strongest Earnings Growth Since 2021 as the 'Other 493' Finally Deliver

For years, the story of the S&P 500 earnings cycle could be summarized simply: a handful of technology giants doing the work for everyone else. The “Magnificent 7”, specifically Alphabet, Amazon, Apple, Meta, Microsoft, NVIDIA, and Tesla, became the engine of earnings growth while most of the other 493 companies in the index delivered mediocre or declining results. Investors accepted the concentration because the big names kept delivering. But the first quarter of 2026 has produced something different and arguably more durable: the broadest earnings expansion the index has seen in nearly five years, with both the megacaps and the broader market posting growth rates that had not been seen since the post-pandemic surge of 2021.

According to FactSet Senior Earnings Analyst John Butters, the blended earnings growth rate for the S&P 500 in Q1 2026 came in at 27.7%, the highest since Q4 2021 when the index posted 32.0% growth in the final throes of the pandemic recovery boom. With all companies having now reported, the picture is comprehensive and the conclusion is clear: corporate America has not been this profitable in four years, and the gains are no longer solely dependent on a few names in Silicon Valley.

The Magnificent 7 Still Lead, But the Gap Has Narrowed

The seven largest technology companies continued to outperform in absolute terms. The “Magnificent 7” posted collective earnings growth of 63.2% in Q1 2026, the highest since Q2 2021 when they grew 89.2% off a depressed pandemic baseline. All seven beat analyst estimates, with an aggregate positive surprise of 32.5%, compared to 16.6% for the broader index. Four of the five top contributors to overall S&P 500 earnings growth in Q1 came from within the group: NVIDIA, Alphabet, Amazon, and Meta.

But the real story is what happened outside those seven names. The other 493 companies in the index posted earnings growth of 17.4% in Q1 2026, also the highest for that group since Q4 2021. After years of struggling to keep pace with the technology heavyweights, companies in industries ranging from industrials to financials to consumer discretionary delivered results that stood on their own merits, not merely as a footnote to Big Tech’s dominance. The gap between the Magnificent 7 and the rest of the market, while still substantial, narrowed meaningfully in the first quarter.

Seven of the eleven S&P 500 sectors reported double-digit earnings growth, led by Information Technology, Communication Services, Materials, and Consumer Discretionary. The only sector to report a year-over-year decline in earnings was Health Care, which has faced headwinds from drug pricing pressures and the recalibration of pandemic-era spending patterns.

What the Numbers Actually Show

Several of the headline figures deserve careful interpretation. The Magnificent 7 earnings include some items that boosted reported profits in ways that may not recur. Alphabet’s Q1 EPS included a net gain of $37.7 billion primarily from unrealized gains on non-marketable equity securities. Amazon reported a pre-tax gain of $16.8 billion from investments in Anthropic. Meta recorded an $8.03 billion income tax benefit; without it, EPS would have been $3.13 lower. These one-time items inflated GAAP earnings significantly for three of the seven companies.

FactSet used GAAP earnings for Alphabet, Amazon, and Meta in its calculations, since most analysts covering those companies submit GAAP estimates. For NVIDIA and Micron Technology, non-GAAP earnings were used, consistent with how analysts model those businesses. NVIDIA reported non-GAAP EPS of $1.87 against GAAP EPS of $2.39, while Micron posted non-GAAP EPS of $12.20 versus GAAP EPS of $12.07.

Stripping out one-time items from the Magnificent 7 results would reduce the headline growth figure for that group, but the broader market’s 17.4% growth rate reflects genuine operating performance. Companies in industrials, financials, and materials did not benefit from unrealized investment gains. Their results came from higher revenues, better margins, and improved operating leverage, the kind of fundamentals that sustain bull markets over time.

Revenue growth tells a similar story. The blended revenue growth rate for Q1 came in at 11.3%, the highest since Q2 2022 (13.9%). All eleven sectors reported year-over-year revenue growth, a uniformity that has not been seen since the early stages of the post-pandemic recovery. Eighty percent of S&P 500 companies beat revenue estimates, above both the five-year average of 70% and the ten-year average of 67%.

Why the Broadening Matters

The concentration risk that defined S&P 500 returns from 2022 through much of 2025 was a genuine concern for many institutional investors and portfolio managers. An index where seven companies account for the overwhelming majority of earnings growth is an index where a bad quarter from any one of those names can significantly damage overall performance. The index becomes structurally vulnerable to the idiosyncratic risks of a small number of companies, their regulatory situations, their capital expenditure cycles, their AI spending commitments, and their exposure to geopolitical tensions in key markets.

A broadening of earnings growth reduces that concentration risk. When industrials grow 15%, when financials beat estimates by double digits, and when materials companies post the kind of results they delivered in Q1, the market’s earnings base becomes more diversified and more resilient. A stumble from NVIDIA or Meta, while still significant, does not carry the same systemic weight when the other 493 companies are also generating meaningful profit growth.

The broadening also reflects something real happening in the broader economy. Demand for manufactured goods, financial services, and physical infrastructure has been stronger than many forecasters expected given the geopolitical disruptions of the past year. The 2026 Iran war created significant uncertainty in energy markets and supply chains, but US corporate earnings proved more resilient to those disruptions than the most pessimistic scenarios had anticipated. Companies adapted, repriced, and in some cases benefited from the volatility in ways that showed up in first-quarter results.

The AI Investment Wave Reaches the Rest of the Economy

One of the more significant shifts visible in Q1 2026 results is the extent to which AI-related capital spending is now flowing through to companies outside the technology sector. The hyperscalers, chiefly Amazon Web Services, Microsoft Azure, and Google Cloud, have been spending at extraordinary rates on data center infrastructure, compute capacity, and energy procurement. That spending does not disappear: it becomes revenue for the companies building data centers, the utilities supplying power, the manufacturers producing cooling systems, and the industrial companies supplying construction materials.

This transmission mechanism explains part of why industrials and materials delivered such strong Q1 results. The AI investment wave has expanded beyond software and semiconductors into the physical economy. Real estate investment trusts focused on data centers have seen occupancy and pricing surge. Power companies supplying hyperscaler facilities have become high-growth businesses by any historical measure. The broader infrastructure buildout required to support the AI compute boom has created a demand cycle that is still in relatively early stages.

Looking ahead, analysts have revised full-year estimates for both groups upward since March 31. The “Magnificent 7” are now expected to grow full-year earnings 34.9%, up from 24.3% estimated at quarter-end. The other 493 companies are projected to grow 17.9% for the full year, up from 14.7%. For the full S&P 500, the consensus estimate is 21.0% earnings growth in 2026, a figure that would represent one of the strongest calendar-year performances in the past two decades.

Valuations Remain Elevated

The earnings growth has come alongside a market that, by historical standards, is not cheap. The forward 12-month price-to-earnings ratio for the S&P 500 stood at 21.0 at the time of FactSet’s May report, above both the five-year average of 19.9 and the ten-year average of 18.9. The index has repriced upward since quarter-end, even as analysts revised estimates higher, meaning the market has moved faster than earnings upgrades alone would justify.

Elevated valuations are not necessarily a signal of imminent correction, particularly in an environment where earnings growth is genuinely broad-based and where interest rate expectations remain relatively benign. But they do mean that the margin for error is narrower. A quarter where the other 493 companies revert to flat growth, or where one or two Magnificent 7 members miss estimates badly, would be felt more acutely by markets that have priced in continued momentum.

The Q2 outlook helps explain why valuations remain where they are. Analysts are calling for earnings growth of 19.9% in Q2, 23.2% in Q3, and 20.7% in Q4. If those estimates hold, 2026 will end as one of the most profitable years for corporate America in a generation. The market is pricing for that scenario. Whether the underlying economy, the geopolitical backdrop, and the AI investment cycle can sustain those growth rates through the rest of the year is the central question for equity investors in the second half.

Memorial Day and the Weeks Ahead

The Q1 earnings season effectively concluded around Memorial Day weekend, with equity markets closed Monday, May 25. Volume will be light as the week opens, and the next major data point for markets will be the FactSet Earnings Insight report due May 29 along with fresh economic data.

What traders return to on Tuesday will be a market that has processed the strongest earnings season in five years, that is sitting near all-time highs, and that has one eye on Iran nuclear deal negotiations that could significantly reshape oil prices and risk sentiment if they conclude. The broadening of earnings growth gives that market a more stable foundation than it had at the start of the year. Whether that foundation holds through the second half depends on factors that no earnings report can fully predict.

What was the S&P 500 earnings growth rate for Q1 2026?

The S&P 500 posted a blended earnings growth rate of 27.7% for Q1 2026, the highest growth rate since Q4 2021 when the index grew 32.0% during the post-pandemic recovery. This represents the sixth consecutive quarter of double-digit year-over-year earnings growth for the index. Revenue growth also hit an 11.3% rate, the highest since Q2 2022.

How did the "Magnificent 7" companies perform in Q1 2026 earnings?

The Magnificent 7 (Alphabet, Amazon, Apple, Meta, Microsoft, NVIDIA, and Tesla) collectively posted earnings growth of 63.2% in Q1 2026, the highest since Q2 2021. All seven beat analyst estimates, with an aggregate positive EPS surprise of 32.5% versus 16.6% for the broader S&P 500. NVIDIA, Alphabet, Amazon, and Meta were four of the top five contributors to overall S&P 500 earnings growth for the quarter.

What does "blended earnings growth rate" mean in the context of S&P 500 reports?

The blended earnings growth rate combines actual reported results for companies that have already reported with estimated results for companies that have not yet reported, producing a single composite growth figure for the index. As more companies report, the blended rate converges toward the actual rate. By late in the earnings season, when nearly all companies have reported, the blended rate is effectively the actual growth rate.

Why is earnings growth broadening important for stock market stability?

When earnings growth is concentrated in only a few large companies, the index becomes vulnerable to idiosyncratic risks specific to those names. If one or two major contributors miss estimates or face headwinds, the impact on overall index earnings is disproportionately large. Broad-based growth across many sectors creates a more resilient foundation: a stumble in one area can be offset by continued strength elsewhere, reducing volatility and supporting more sustainable valuations.

What is the S&P 500 earnings outlook for the rest of 2026?

Analysts project earnings growth of 19.9% for Q2, 23.2% for Q3, and 20.7% for Q4 2026. For the full calendar year, the consensus estimate is 21.0% earnings growth. Full-year estimates for both the Magnificent 7 (34.9%) and the other 493 S&P 500 companies (17.9%) were revised upward since March 31, reflecting the strength of Q1 results and improved forward guidance.

What is the current S&P 500 forward P/E ratio and how does it compare to historical averages?

The forward 12-month price-to-earnings ratio for the S&P 500 stood at 21.0 as of FactSet's May report, above both the five-year average of 19.9 and the ten-year average of 18.9. The elevated valuation reflects market optimism about continued strong earnings growth, but also means the market has less margin for error if earnings momentum slows.
