Default risk, three ways
Stock market: distance-to-default
Distance-to-default 5.59: safer than 54% of companies (53th percentile in Technology). Market-implied, prices to 2026-10-16, balance sheet 2026-07-03.
| Equity value | $150.30B |
| Debt barrier (short-term + ½ long-term debt) | $1.88B |
| Equity volatility (1 year) | 75.4% |

Bond market: priced-in odds
A 138 bp spread prices in about 2.3% 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'' = 2.31 (latest balance sheet). A fundamentals cross-check; see methods for the variant used.
The stock side: 13F filings
What institutions report holding in STX'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.
