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.

Olin Corp earns a C (Mixed — selective) forensic quality grade, and its balance-sheet distress test reads 1.6, 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

0.1%
FY2025
Return on invested capital. Return on invested capital is 0.1% in the latest fiscal year and slipping across FY2023–FY2025 from 9.4%. After-tax operating profit was $575M in FY2023 and $4M in FY2025, with operating income at 10.4% of revenue in FY2023, 4.5% in FY2024 and 0.1% in FY2025. The capital base behind it went from $6.1B in FY2023 to $5.8B in FY2025 (-5%), while the revenue it carried went from $6.8B to $6.8B. FY2025's operating profit carried a $33M restructuring charge that alone took about 0.5 points off that year's return, so about 0.5 of the 9.3-point fall across FY2023–FY2025 is that charge landing in the latest year rather than the capital earning less.
