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, going concern, valuation). 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 4.9, placing it in the Safe zone. 3 forensic signals were flagged in its latest SEC filings, led by return on invested capital.
What the filings flag
6.3%
FY2025
Return on invested capital.Return on invested capital is 6.3% 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 barely moved across FY2023–FY2025 ($7.9B to $7.5B, -5%), so there has been little new capital for that return to be earned on. 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 21.9-point rise across FY2023–FY2025 is that charge leaving the base year rather than the capital earning more.
+0.7%/yr
FY2023–FY2025
Share count.Diluted share count changed +1% over the last 2 years to FY2025 (+0.7%/yr). Roughly flat — buybacks ($45M) are about offsetting stock comp ($55M), not shrinking the count. Per-share value isn't being meaningfully helped or hurt by the count.
$1.7B
FY2023–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.
