AppLovin reported a 76% operating margin in FY2025 — the highest among all major tech peers. But a line-by-line decomposition of the 10-K reveals that roughly half of the margin expansion came from a collapsing stock compensation pool, not operational efficiency. With 920,526 PSU grants tied to $300B–$1T market cap milestones, the mechanism for SBC reversal is already embedded. Meanwhile, 97% of revenue growth came from pricing, not volume — and the filing's own risk factors warn that growth will decelerate.
Dell Technologies reported record $113.5 billion in revenue and 36% EPS growth for fiscal 2026. But buried in the segment footnote of the annual report, ISG gross margin collapsed 550 basis points in a single year — even as the segment's operating income grew 30%. The company's $26 billion services layer and disciplined SG&A efficiency are masking a fundamental shift in earnings quality that the earnings release doesn't show.
UnitedHealth Group grew Medicare Advantage membership by 600,000 in FY2025 and revenue surpassed $447 billion. Operating income fell 41%. The FY2025 10-K reveals a medical cost ratio of 89.1% — the worst trajectory among five managed care peers we analyzed from raw filing data. UNH's +5.9 percentage point MCR deterioration is nearly double the peer average, exposing the vertical integration model as a cost amplifier, not a dampener.
Boston Scientific has 69% gross margins. Abbott has 56%. Yet Abbott's ROIC is 2.6x higher. This paradox reveals something fundamental about capital efficiency in medical devices—and why screening for 'high margin' stocks can lead you astray.
The conventional wisdom says Visa is the safer, higher-quality payment stock. Our ROIC analysis tells a different story: Mastercard's 78% ROIC dwarfs Visa's 36%, and the reason reveals something important about how to read these metrics.
Wall Street treats homebuilders as a monolithic 'housing play.' But our analysis reveals a 4x ROIC spread (NVR 35% vs LEN 9%) that cannot be explained by margins alone. The divergence stems from three structural factors: NVR's asset-light lot model vs LEN's Millrose spin-off creating structural margin compression, DHI's $26B in specific performance land contracts creating downside asymmetry, and NVR's paradoxically 'cautious' guidance signaling genuine competitive strength.
Wall Street loves CVNA's +30% ROIC turnaround story. But our 8-quarter trajectory analysis reveals CarMax is in crisis mode: CEO fired December 2025, forced margin cuts, -8% volume decline. The data shows this isn't online vs traditional—it's about execution quality.
Devon Energy generated 48% ROIC in Q3 2025. ExxonMobil generated 11%. Both produce oil and gas. Why the 4.5x difference? The answer lies in capital allocation: XOM returns 73% of FCF as dividends while pure E&P operators reinvest in high-return wells.
Qualcomm's consolidated margins hide a secret: the QTL licensing segment earns 72% operating margin vs QCT hardware's 30%. When Apple moves fully to in-house modems, what happens to QCOM's profitability? Our semiconductor ROIC comparison reveals the answer.
Wall Street ranks Lockheed Martin's 30% ROIC as best-in-class. But our 8-quarter trajectory analysis reveals LMT's capital efficiency is actually declining (-0.018 trend) while RTX improves (+0.004). The data suggests the market may be mispricing defense contractor quality.
