Earnings season comes with a wall of jargon: "beat on the top line," "adjusted EPS," "guided below consensus." Here's what each piece means, with real examples from this season.
EPS: the headline number
EPS (earnings per share) = net income ÷ number of shares.
- Diluted EPS includes shares that could be created from stock options or convertible bonds. It's the one to use.
- A company can grow profit and still have flat EPS if it issues lots of new shares.
What a "beat" actually is
Before results, analysts publish estimates. The average is the consensus. If the company reports above it, that's a beat. Below is a miss.
Beats are common. As of Oct 16, 2026, with 9% of the S&P 500 reporting Q3, FactSet said:
- 84% had beaten EPS estimates (5-year average: 78%).
- In aggregate, earnings were only 2.6% above estimates (5-year average: 7.5%).
- 67% had beaten revenue estimates (5-year average: 70%).
So "beat" by itself tells you little. How much matters, and so does what's coming next. Season context: Micron, NVIDIA and S&P 500 growth.
GAAP vs non-GAAP (adjusted)
- GAAP is standard U.S. accounting. It's what auditors sign off on in the annual 10-K. (Quarterly 10-Qs are unaudited, per Investor.gov.)
- Non-GAAP or "adjusted" numbers strip out items the company considers unusual or non-cash.
Investor.gov says companies can show non-GAAP measures but must reconcile them to the closest GAAP number, and "it is up to you to decide how much weight to give" them.
Examples from this season:
- Tesla Q3 2026: GAAP EPS $0.22, non-GAAP $0.48 (our Tesla breakdown).
- Microsoft FY26 Q4: non-GAAP results exclude the impact of its OpenAI investments, per its Jul 29 release. GAAP EPS was $4.81; non-GAAP $4.74.
Always check what's in the adjustment, and whether it happens every quarter.
Guidance: the forward-looking part
Guidance is the company's own forecast. NVIDIA, for example, guided on Aug 26, 2026 to revenue of $108.0B ±2% for its October quarter, per its release (NVIDIA preview).
Guidance often moves a stock more than the quarter just reported. On Jul 22, 2026, Alphabet posted $119.8B of revenue, above the $116.93B LSEG consensus, yet its shares fell more than 4% after hours when it raised its 2026 capex forecast to $195B–$205B, CNBC reported.
A 5-minute checklist
- Revenue vs a year ago and vs consensus.
- Diluted EPS, GAAP and adjusted. What's the gap?
- Margins: gross and operating.
- Cash flow: operating cash flow minus capex = free cash flow.
- Guidance: up, down or unchanged?
- One-offs: gains on investments, restructuring, impairments (impairment explained).
