| Equity value | $114.54B |

Bond market: priced-in odds
A 106 bp spread prices in about 1.8% 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 = 5.15 (latest balance sheet). A fundamentals cross-check; see methods for the variant used.
