VST enters its August 5 earnings report after a sharp short squeeze that has left the stock down 9% on the week but with dramatically reduced bearish positioning.
The most striking development in the run-up has been the collapse in short interest. Bears cut positions by more than 20% in a single week and by over 26% in the past month, with shares short falling to roughly 12.2 million — equal to 3.6% of free float. That unwind began abruptly around July 22, when short interest dropped from roughly 15.4 million shares to around 12.4 million in a single session. The borrow market reflects the same retreat: cost to borrow fell 23% over the week to a very low 0.34%, and share availability has ballooned to the point where it far exceeds any constraint on further shorting. The ORTEX short score has dropped from the high 38s to 34.9, consistent with the easing of bearish pressure. Options positioning is broadly neutral, with the put/call ratio at 0.89 — fractionally below its 20-day average of 0.89 and nowhere near defensive territory. The week's 9% pullback, which mirrors similar declines in closely correlated peers TLN (down 7%) and TA (down 9%), looks more like a sector-wide reset than a VST-specific selloff.
The Street remains firmly bullish despite trimming targets. Morgan Stanley raised its price target to $212 last week while keeping an Overweight rating. UBS and TD Cowen both lowered targets modestly — to $227 and $222 respectively — but held Buy ratings. The mean analyst target sits near $222, implying roughly 50% upside from the current $148 price. Bulls point to the Cogentrix acquisition lifting EBITDA forecasts, a target of 60%-plus free cash flow conversion in 2026, and strong retail margin expansion as catalysts that justify the premium. Bears counter that the stock has already shed about 30% from its peak and faces real commodity cost volatility — with VST previously flagging up to $1.6 billion in adverse EBITDA effects from fuel and power procurement swings. The PE multiple sits near 15.6x and EV/EBITDA near 9.4x, both broadly stable over the past month, suggesting valuation has at least stabilised after the pullback.
The earnings history adds a cautionary note. After the May 2026 print, VST fell 6.7% on the day and extended losses to just over 10% across the following five trading sessions. The prior Q4 report produced a smaller 1.6% drop on the day but also ended the week about 9% lower. Both recent prints resolved to the downside, even when operational results were constructive.
The August 5 report will test whether the bullish free cash flow conversion story is gaining traction — or whether ongoing commodity cost pressure is eroding the EBITDA upside that justifies the Street's still-elevated targets.
