FUNDAMENTAL SCORE
82 / 100
Summary
Ciena reported mixed multi-year results with revenue compounding at 9.5% a year (CAGR, or compound annual growth rate) while net income compounded at -6.9% a year. Latest annual revenue rose 18.8% YoY (year-over-year) and latest annual net income rose 46.9%, and the most recent quarter reported $266.42M in net income, up 22.1% QoQ (quarter-over-quarter). Assets cover liabilities 1.87 times, a solid balance-sheet cushion. The Altman Z-score is 9.32, which sits in the safe zone given the distress threshold of 1.81 and the safe threshold of 2.99. One annual result is flagged as an extreme outlier that materially distorts the three-year net-income CAGR, so the multi-year decline in reported net income is a tentative read. The Piotroski F-Score of 7 on a 0 to 9 quality scale is a strong earnings-quality signal, and the price-to-earnings ratio of 368.1 is approximately 15 times the S&P 500 average. The next earnings report must show whether quarterly net income growth persists and normalizes the multi-year net-income trend.

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.
