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.

Mks Inc earns a B (Sound & dependable) forensic quality grade, and its balance-sheet distress test reads 2.3, placing it in the Grey zone. 2 forensic signals were flagged in its latest SEC filings, led by return on invested capital.

What the filings flag

6.4%

FY2025

Return on invested capital. Return on invested capital is 6.4% in the latest fiscal year and rising across FY2023–FY2025 from -15.6%. After-tax operating profit was ($1.2B) in FY2023 and $475M in FY2025, with operating income at -42.9% of revenue in FY2023, 13.9% in FY2024 and 13.4% in FY2025. The capital base behind it went from $7.9B in FY2023 to $7.5B in FY2025 (-5%), while the revenue it carried went from $3.6B to $3.9B. FY2023's operating profit carried a $1.7B goodwill write-off and a $20M restructuring charge that alone took about 17.2 points off that year's return, so about 17.2 of the 22.0-point rise across FY2023–FY2025 is that charge leaving the base year rather than the capital earning more. A non-cash write-down lowers the reported return in the year it lands.

$1.7B

FY2023

Goodwill impairments. Took $1.7B of goodwill writedowns across 1 year (FY2023 ($1.7B)). Writedowns mean past acquisitions underperformed what was paid for them.
