VST — Aug 165/200 call debit spread
Vistra reports Aug 6 with contracted backlog of $7.47B in Q1'26, up 168% year over year on ERCOT and nuclear demand, yet the stock is down 12% over the trailing year and sits ~24% below its 52-week high of $219.21. Same catch-up shape as Constellation, with a 54% implied vol pricing an 18.7% move. The long 165/short 200 call spread expresses a re-rate into the print at a defined 11.2 cost.

What invalidates this thesis
A warm-weather demand miss or softer ERCOT capacity pricing keeps the stock range-bound below 176, and the debit decays to zero if VST does not clear the breakeven by expiry.
