Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

The companies
EXPOExponent, Inc.
Engineering & Construction · $69.81 · beta 0.70
Why now
Engineering & Construction · market cap $3.3b. 15% off the 52-week high of $81.95. Revenue growing +13%, comfortably above the S&P median. 3 sell-side analysts rate this a Buy with a mean 1-yr target of $84.00 (implying +20% upside).
Moat
Net margin 18% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 39% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 97% of net income — earnings translate cleanly into cash.
Risk
Trailing P/E 31x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
PWRQuanta Services, Inc.
Engineering & Construction · $705.94 · beta 1.27
Why now
Engineering & Construction · market cap $106.1b. 10% off the 52-week high of $788.75. Revenue growing +26% — in hypergrowth territory. 29 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $766.01 (implying +9% upside).
Moat
ROE 14% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 180% of net income — earnings translate cleanly into cash. $106.1b market cap gives the company enough scale to absorb fixed costs that subscale competitors can't, without yet being so large that growth has to come from acquisition.
Risk
Trailing P/E 78.5x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Net margin 4.0% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first.

Pillars run 0–100. Value is judged against each company's own sector, so a Value score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
Common questions
Is EXPO or PWR the better stock?
EXPO scores higher: EXPO 77.1, PWR 52.5 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.
Where do EXPO and PWR differ most?
The widest gap is value, where EXPO leads by 37 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.
How are EXPO and PWR scored?
Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
How current is this comparison?
The whole universe is re-scored every trading day after the US market close, so the scores and fundamentals here reflect the latest published edition.
