77 / 100
Summary
Costco reported accelerating top- and bottom-line growth. Revenue compounded at 7.8% a year (CAGR, or compound annual growth rate) over three years while net income compounded at 13.6% a year; latest annual revenue rose 10.1% YoY (year-over-year) and net income rose 13.9% YoY. The most recent quarter posted $2.19B in net income and net income direction is improving QoQ (quarter-over-quarter). Assets cover liabilities 1.67 times, which is a solid balance-sheet cushion. The Altman Z-score is 9.34, which sits well above the safe threshold of 2.99 for the Z (1968) variant. The Piotroski F-Score of 6 on a 0 to 9 quality scale indicates mixed earnings quality. With a P/E of 48.4, roughly 2.1 times the S&P 500 average, the next report must show whether net income growth sustains and whether margins or cash flow justify the multiple.

Data Source
This dashboard applies a modified 9-signal Piotroski F-Score (Piotroski, 2000) and Altman Z-Score models. Fundamental filing data is sourced from the SEC's EDGAR XBRL database (primary), with API Ninjas as backup for freshly-filed 10-Ks not yet in SEC. Live price, market cap, and EPS display use Tiingo end-of-day data. This page is informational analysis, not investment advice. See Financial Disclaimer.

Formula & Methodology
Trend inputAnnual revenue and net income year-over-year direction contributes 20% of the score.
Piotroski inputModified 9-test Piotroski F-Score (Quality) contributes 40% of the score.
Altman inputAltman Z-Score (Distress) contributes 40% of the score.
Rating ruleFormula: Trend (20%) + Piotroski F-Score (40%) + Altman Z-Score (40%). Trend blends annual revenue and net income year-over-year direction. Piotroski is the modified 9-test variant (7 classic + 2 cash-flow tests). Altman uses the 1968 Z-Score with Safe/Grey/Distress zones. Combined blend uses ±0.45 thresholds: Bullish at +0.45 or higher, Bearish at -0.45 or lower, Neutral in between. Missing sub-signals count as Neutral (0) and weights are not re-normalized — a company with fewer available signals must earn its rating from stronger reads on the remaining pillars.
