Q1 Earnings Smash Expectations — Blended Growth at 15.1%, Profit Margins Hit Record 13.4% Since 2009

Q1 2026 earnings season has materially exceeded expectations: blended year-over-year earnings growth at 15.1% (versus 13.1% expected at end-March). Profit margins hit a record 13.4% — the highest level since 2009. The forward 12-month S&P 500 P/E sits at 20.9, above both the 5-year average of 19.9 and the 10-year average of 18.9.

The Headline Numbers

Blended Q1 2026 EPS growth: 15.1% YoY (vs 13.1% expected end-March)
Profit margin: 13.4% — record since 2009
Forward 12M S&P 500 P/E: 20.9
5-year average P/E: 19.9
10-year average P/E: 18.9

The Macro Wrap

Real GDP +2.0% annualised in Q1 2026
Up from 0.5% in Q4 2025 — meaningful acceleration
Wages outpaced inflation by 1.4% YoY (Feb 2025 → Feb 2026)
Real-economy backdrop more resilient than the bear-case scenarios assumed

The Big Tech Divergence

Alphabet +34% in April on Q1 beat across cloud, advertising, Waymo
Meta -9% after raising 2026 capex guidance to $125–145 billion
Capex-vs-monetisation tension is the new market discriminator
Companies that can monetise AI investment outperform; those still building underperform

Why The 15.1% Is Striking

Beats by 200 basis points vs March consensus — a wide miss-to-the-upside
13.4% margin = first time at 2009 levels — supports the “AI productivity dividend” narrative
Validates 2026 earnings models that bake in sustained margin expansion
Justifies — partially — the elevated forward P/E

The Caveats

P/E at 20.9 is rich vs 10Y average — leaves less margin for misses next quarter
Tech-driven layoffs (separate story) suggest cost-out is part of the margin story
Geopolitical risk premium could compress multiples quickly
Iran-related oil spikes could re-introduce cost pressure into Q2 prints
