Default risk, three ways
Stock market: distance-to-default

Bond market: priced-in odds
A 229 bp spread prices in about 3.8% a year of default odds (spread ÷ (1 − 40% recovery)). Fund-reported marks as of Jul 2026; the spread also pays for liquidity and risk premium, so this overstates actual defaults.
Accounts: Altman Z
Altman Z = 1.93 (latest balance sheet). A fundamentals cross-check; see methods for the variant used.
The stock side: 13F filings
What institutions report holding in AMTM's stock and options. Options are reported at the value of the underlying shares, not the premium paid; 13F lists long positions only, lags 45 days after quarter-end, and does not show whether puts hedge a stock position.
