FUNDAMENTAL RATING
FUNDAMENTAL SCORE
39 / 100
Summary
American Tower shows a near-term solvency concern: its Altman Z-score is 0.03, which sits below the distress threshold of 1.1 and well under the safe threshold of 2.6. The company has mixed growth signals: revenue compounded at -0.2% a year (CAGR, or compound annual growth rate) while net income compounded at 15.7% a year. Latest annual revenue rose 5.1% and latest annual net income rose 15.3%, and the most recent quarter reported $887.5M in net income, up 1.0% QoQ (quarter-over-quarter). Assets exceed liabilities by 1.20 times, providing a limited cushion. The Piotroski F-Score of 5 on a 0 to 9 quality scale is a mixed earnings-quality reading, and the price-to-earnings ratio of 34.9 is roughly 1.5 times the S&P 500 average. The next earnings report must show whether net income growth reaccelerates and whether balance-sheet metrics move away from distress levels.

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.

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.
