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.
Nn Inc earns an F (Poor — capital at risk) forensic quality grade, and its balance-sheet distress test reads -0.8, placing it in the Distress zone. 6 forensic signals were 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 steady — well below its ~9% cost of capital, and it has been across FY2014–FY2025, so reinvested dollars have not been earning their keep.
+3.4%/yr
FY2022–FY2025
Share-count dilution.Diluted share count changed +11% over the last 3 years to FY2025 (+3.4%/yr). The count is growing: more stock was issued than repurchased over this window, so aggregate results grew faster than their per-share equivalents. That's ~3.4% shaved off per-share growth every year — total profit has to grow that much just to keep earnings-per-share flat, and a stake held since FY2022 has been diluted ~10%.
stopped
FY2019→FY2021
Shareholder returns — halted.Capital returns have STOPPED — $9M of buybacks + dividends in FY2019, but ~$0 in FY2021. A halt usually means the company is conserving cash.
suspended
FY2019→FY2021
Dividend — suspended.The dividend has been SUSPENDED — $9M paid in FY2019, then $0 in FY2021. A suspension is a major signal the board is conserving cash; the prior payment history doesn't offset it.
0.8% of rev
FY2025
Stock-based comp load.Stock-based compensation ran 0.8% of revenue in FY2025 — about $0.06 per diluted share. No cash left the business to pay it, which is why operating cash flow adds it back. Net of repurchases the diluted count still rose about 3.4% a year, and the rate is falling. Stock compensation is one source of that issuance; acquisition consideration, equity raises, convertibles and other employee plans also net into the count, and these figures do not separate them.
