How to Compare Earnings Across Companies: Revenue, EPS, Margins and Cash Flow — the 5-Number Checklist That Beats the Headline

Earnings season produces a flood of headlines — "beats", "misses", "raises guidance" — and most of them are useless on their own. A company can beat earnings and fall, miss revenue and rise, or report record profit while its stock slides. The reason is simple: the market does not react to a single number. It reacts to five numbers together, compared with what was already expected, and with what management says comes next. This guide teaches that comparison, with real November 3, 2026 prints as worked examples.

Number 1: Revenue — did the business actually grow? Revenue is the top line: how much the company sold. Compare it two ways at once — against the consensus estimate, and against the same quarter last year. A revenue miss with an earnings beat is a warning sign, not a victory lap, because it usually means profit came from cost-cutting or one-offs rather than from selling more. On November 3, HNI showed exactly that pattern: earnings of $1.62 per share beat the $1.39 consensus, but revenue of $1.59 billion came in just under the $1.60 billion estimate. Archrock did the same in reverse proportions: $0.49 per share beat the $0.4511 estimate, while revenue of $370.81 million missed the $385.95 million consensus. In both cases, the right question is not "did it beat?" but "which line beat, and which missed?"

Number 2: Earnings per share — GAAP or adjusted, and by how much? EPS is profit divided by shares outstanding, and companies report two versions: GAAP earnings, which follow strict accounting rules, and adjusted (non-GAAP) earnings, which strip out items management calls one-off. Always check which version the "beat" refers to, and how big the beat is in percentage terms, not just cents. Upstart on November 3 is a clean example: $0.33 per share against a $0.2015 consensus — a large percentage beat — with revenue of $370.52 million against $362.68 million expected, so both lines beat together. Ball Corporation is the quieter version: $1.10 per share against $1.07 expected — a small beat that says "in line, slightly better", not "breakout". A 60% beat and a 3% beat are not the same news, even though both get the same headline word.

Number 3: Margins — is the profit getting better or worse? Margins measure how much of each sales dollar survives as profit: gross margin (after production costs), operating margin (after running the business) and net margin (after everything, including interest and tax). Rising revenue with falling margins means the company is selling more but keeping less — often a sign of discounting, rising input costs or price competition. Falling revenue with rising margins can mean the opposite: a smaller, more disciplined business. When you compare two companies in the same sector, margins are the fairest comparison of all, because they strip out size: a small company and a giant can both be judged on how efficiently they turn sales into profit.

Number 4: Guidance — what management says comes next moves the stock most. Guidance is management's own forecast for the next quarter or the full year, and it routinely matters more than the quarter just reported, because markets price the future. A raise (higher forecast), a cut, or a reaffirmation each send a different signal — and so does the width of the range: a narrow range signals confidence, a wide range signals uncertainty. On November 3, BETA Technologies raised full-year 2026 revenue guidance to $52 million to $57 million, while Archrock reaffirmed full-year adjusted EBITDA guidance of $865 million to $885 million. A reaffirmation after a mixed quarter is not neutral news: it says management still believes the original plan, which is itself a claim worth testing against the next quarter's numbers. Always read guidance alongside the beat or miss — a beat with a guidance cut is often a sell signal, and a miss with a guidance raise is often forgiven.

Number 5: Cash flow and the balance sheet — can the profit pay for itself? Profit on paper is not cash in the bank. Free cash flow — operating cash flow minus capital spending — shows whether the business generates cash after keeping itself running. A company with rising profit but falling free cash flow may be tying up cash in inventory or receivables, or spending heavily to grow. Pair this with the balance sheet: debt levels, leverage (debt relative to earnings), dividends and buybacks. Archrock's November 3 call is a useful illustration of the language to listen for: long-term debt of $2.3 billion, a leverage ratio down to 2.5 times from 3.1 times a year ago, a quarterly dividend of $0.23 per share held steady, and $113.2 million of buyback capacity remaining. None of those figures is a headline — together, they describe a company with room to return cash and room to invest, which is exactly what a comparison across companies should surface.

The comparison, step by step. Put two companies side by side and run the same five checks on both, in the same order, before looking at either stock's move. First, revenue: estimate beat or miss, and year-on-year growth. Second, EPS: which version, and by what percentage. Third, margins: expanding or contracting, and versus the sector. Fourth, guidance: raised, cut or reaffirmed, and how wide the range is. Fifth, cash flow and balance sheet: free cash flow direction, debt and leverage, dividends and buybacks. Only then ask what the stock did — and if the stock moved the opposite way to your checklist, treat that as information, not as an error: it usually means expectations were already priced in, or the earnings call said something the release did not.

The trap to avoid. The single biggest earnings trap is judging a quarter by one word. "Beat" without saying which line, by how much, and what guidance did, is marketing, not analysis. The second trap is comparing companies on different bases — one company's adjusted EPS against another's GAAP EPS, or one quarter's revenue against a different quarter's. Same lines, same basis, same checklist, every time. That discipline is boring, and it is the whole edge: most market commentary skips it, which is why most earnings headlines mislead.

FAQ

What is the difference between a revenue beat and an earnings beat? Revenue is sales; earnings per share is profit per share. A company can beat one and miss the other — HNI and Archrock both did exactly that on November 3, 2026.

Should I use GAAP or adjusted EPS? Compare like with like: check which version the consensus used, and note what was stripped out of the adjusted figure before trusting it.

Why do margins matter if revenue is growing? Because rising sales with falling margins mean the company keeps less of each dollar — a sign of discounting, cost pressure or competition.

Why does guidance move stocks more than the reported quarter? Because markets price the future: a raised, cut or reaffirmed forecast changes what investors expect next quarter and next year.

What is free cash flow, and why check it? Operating cash flow minus capital spending — the cash left after running and maintaining the business. Profit without cash flow is a claim, not yet a fact.

Why did a stock fall after a beat? Usually because the beat was already expected and priced in, guidance disappointed, margins contracted, or the earnings call revealed something the release hid.
