Rewards
IRM

- ★Net debt/EBITDA of -2.6x means the company holds more cash than debt — a net cash position.
Risks
IRM
- ⚠Net debt/EBITDA of 7.9x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
- ⚠Altman Z-Score of 0.83 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
- ⚠10 insider sales totaling $63.6M with no purchases in the past 3 months — insiders are reducing their exposure.
TSLA
- ⚠ROIC has declined by 17.7 percentage points over the observed period, which may signal competitive erosion.
- ⚠Gross margin of 19.1% is low, suggesting a competitive or commodity-like market with limited pricing power.
- ⚠Share count has increased by 19% over the past 4 years, diluting existing shareholders.
