Risks
AMT
- ⚠FCF yield of 5.3% suggests reasonable valuation assuming continued moderate growth.
- ⚠High leverage (4.34x debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
- ⚠Net debt/EBITDA of 6.3x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
NOW
- ⚠Despite buyback spending, shares outstanding increased in 3 out of 3 years — stock-based compensation is offsetting repurchases.
- ⚠PEG ratio of 19.95 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
