AEE
    UNH
    • Dividend yield of 2.40% with a consistent or growing payout over the past 4 years.

    • Net debt/EBITDA of 5.3x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
    • Altman Z-Score of 0.91 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
    • 6 insider sales totaling $4.4M with no purchases in the past 3 months — insiders are reducing their exposure.
    UNH
    • ROIC has declined by 7.9 percentage points over the observed period, which may signal competitive erosion.
    • Gross margin of 18.8% is low, suggesting a competitive or commodity-like market with limited pricing power.
    • FCF yield of 5.3% suggests reasonable valuation assuming continued moderate growth.

An M-Score above -1.78 signals elevated risk — companies in this range have historically been 3-5× more likely to be manipulating earnings. Scores between -2.22 and -1.78 fall in a grey zone warranting further investigation.
