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 (red flags, auditor quality, say on pay, board independence). 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.

Diodes Inc /Del/ earns a B (Sound & dependable) forensic quality grade, and its balance-sheet distress test reads 12.4, placing it in the Safe zone. 2 forensic signals were flagged in its latest SEC filings, led by return on invested capital.

What the filings flag

1.7%

FY2025

Return on invested capital. Return on invested capital is 1.7% in the latest fiscal year and slipping from 23% — well below its ~10% cost of capital, so reinvested dollars may be destroying value, not building it.

+0.3%/yr

FY2022–FY2025

Share count. Diluted share count changed +1% over the last 3 years to FY2025 (+0.3%/yr). Roughly flat — buybacks ($34M) are about offsetting stock comp ($26M), not shrinking the count. Per-share value isn't being meaningfully helped or hurt by the count.
