This free snapshot doesn't read filing or proxy text, so the auditor-quality and governance checks that can lower a grade were not evaluated (auditor quality, say on pay, board independence, going concern). Those checks only ever lower a grade, so the full analysis can land below the grade above but never above it — treat it as the most favourable reading, not the settled one.

Ciena Corp earns a B (Sound & dependable) forensic quality grade, and its balance-sheet distress test reads 1.9, placing it in the Grey zone. 1 forensic signal was flagged in its latest SEC filings, led by return on invested capital.

What the filings flag

4.3%
FY2025
Return on invested capital. Return on invested capital is 4.3% in the latest fiscal year and slipping across FY2023–FY2025 from 7.7%. After-tax operating profit was $282M in FY2023 and $156M in FY2025, with operating income at 8.2% of revenue in FY2023, 4.1% in FY2024 and 4.1% in FY2025. The capital base behind it went from $3.7B in FY2023 to $3.6B in FY2025 (-2%), while the revenue it carried went from $4.4B to $4.8B. FY2025's operating profit carried a $112M restructuring charge that alone took about 2.5 points off that year's return, so about 2.5 of the 3.4-point fall across FY2023–FY2025 is that charge landing in the latest year rather than the capital earning less.
