MasTec Inc. (MTZ) — RQD Stock Rating Cockpit

Per the Roarable RQD rating, MTZ scores 40 out of 100, graded D-, with the verdict "Roarable Sell — Vulnerable Balance Sheet & Flow." The five pillars are: Fundamental Cash Engine at 7/20 (ROIC 6.8%; FCF yield -0.68%), Whale 13F Flow at 6/20 (institutional accumulation and options positioning), Insider Conviction at 8/20 (SEC Form 4 and Congressional PTR cluster flow), Macro Regime Fit at 3/20 (Beta 0.87; sector sensitivity), and Forensic Balance Sheet at 16/20 (Altman Z 3.41; Piotroski F 8/9; Debt/Equity 0.85).

The pattern is uneven. The strongest pillar is the forensic balance sheet, which indicates the company's solvency and accounting-quality markers are comparatively sound by the rating's measures. The weakest pillars are Macro Regime Fit and the Fundamental Cash Engine. The cash-engine score is weighed down by a negative FCF yield, meaning the trailing free-cash-flow figure does not currently support the equity valuation on a cash basis. For a prospective investor, the rating's implication is that upside depends on cash generation improving rather than on balance-sheet strength alone. Valuation is a central tradeoff: the stock trades at 35.8x trailing earnings and 30.1x forward earnings, so the market is pricing in substantial future earnings growth against a current cash profile that the rating treats as vulnerable. Flow pillars (13F and insider activity) are mixed-to-weak, offering limited independent confirmation of conviction. These are educational observations drawn from the rating's structure, not a recommendation.
