⚠ Ten Minutes to Leave, and Nothing to Stop ThemModerate threat
Vistra (VST) — threat to the moat
Losing counts costs the retail margin twice, because the book is also the hedge.
Retail electricity in a deregulated market is the weakest customer relationship in this collection. There is no contract of any length for most residential customers, no equipment to move, no data to migrate, and a state-run comparison site whose purpose is to make leaving simple.
What holds the book together is inertia, and inertia is cheap for a competitor to attack. A retailer willing to accept a lower margin can buy customers with a headline rate, and the acquisition cost is recovered over a relationship that may not last.
The economics are correspondingly thin. Retail earned $1,622 million of Adjusted EBITDA1 serving roughly five million customers2 — a few hundred dollars per customer per year, before the cost of acquiring the next one. This is a volume business with a permanent marketing bill.
It also concentrates the risk in exactly the wrong place. The strongest argument for the retail arm is that it hedges the generation, and the hedge is only as large as the customer book. A retailer losing counts is simultaneously losing margin and losing the offset that makes the generation position safer.
The disclosure to watch is retail customer counts, which Vistra discusses qualitatively rather than reporting as a headline series. A year in which retail Adjusted EBITDA rises on price while counts fall is the pattern that precedes trouble.
