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.

Merck & Co., Inc. earns an A (High-quality, not compounding) forensic quality grade, and its balance-sheet distress test reads 4.2, placing it in the Safe zone. 1 forensic signal was flagged in its latest SEC filings, led by shareholder returns.

What the filings flag

107% of FCF
FY2025
Shareholder returns. Returned $13.3B to shareholders (buybacks + dividends) in FY2025 — 107% of free cash flow. That is $900M (7%) more than free cash flow covered. New debt covered it: total debt rose $12.2B over FY2025, while cash, short-term investments and long-term marketable securities rose $1.4B. That ratio has been CLIMBING past free cash flow — 96% of free cash flow two years back — not just sitting there. Counting the $820M of stock-based comp paid out in shares on top of that, the combined claim on free cash flow is 114%.
