FLNC Jumps 24% Into Earnings — But Shorts Aren't Blinking

Fluence Energy heads into its Q3 earnings release on August 6 with a dramatic split: the stock has surged 24% in a week, yet short sellers holding more than a fifth of the float have barely moved.

The short interest story is the central tension here. Bears hold 20.5% of the free float — a genuinely elevated position that has crept up 7.3% over the past month as the stock sold off. This week's rally hasn't triggered meaningful short covering. Shares short ticked up a fraction on the day, adding roughly 45,000 shares to reach 26.9 million. That tells you shorts are not panicking into earnings — they're holding. The borrow market supports their patience. Cost to borrow is negligible at 0.49%, down 10% on the week, and availability has actually loosened, running at 178% — nearly twice the short interest base, meaning new positions can be opened cheaply. The 52-week low in availability was 2.9%, so the current setup is nowhere near squeeze territory. Options traders read the same way. The put/call ratio is 0.24, sitting barely half a standard deviation above its 20-day average of 0.24 — one of the most call-skewed setups in the past year, with the 52-week PCR high at 0.86. Bulls are pressing calls into the print; bears are in no hurry to cover.

The Street is divided, and recent moves illustrate that cleanly. Citigroup upgraded to Buy on July 22 while cutting the target from $26 to $24 — a cautious upgrade that acknowledges momentum without committing to the old valuation. Truist initiated at Hold with a $16 target, almost exactly where the stock was trading before this week's move. GLJ Research launched coverage at Buy with a $26 target on July 1. The consensus sits at Hold across 18 analysts, six of them bullish, with a mean target of $18.67 — implying about 19% upside from the current $15.67 close. The bull case centres on a growing data centre pipeline, strong FY27 backlog conversion, and a cleaner supply chain story. Bears point to thin gross margins, vertical competition from the likes of Tesla Energy and BYD, and heavy dependence on a narrow customer segment. The EV/EBITDA multiple has compressed roughly 6% over 30 days to 16.7x, and the PE sits at an eye-watering 240x trailing earnings — a valuation that lives or dies on forward execution. The ORTEX analyst recommendation divergence factor scores in the 93rd percentile, flagging unusually wide disagreement on the name.

The ownership picture adds a notable overhang. Siemens remains the largest holder at 14.9% of shares. Back in May, both Siemens Pension Trust and AES Corp each sold just over 10 million shares at around $20-21 — a combined disposal worth more than $418 million at the net level over 90 days. That block sale reset the stock's register significantly. More recently, SVP John Zahurancik sold $755,000 of stock in late June at prices between $22 and $25 — levels well above today's close. The insider flow has been one-directional: every open-market transaction in the past three months has been a sale.

The earnings history adds another dimension. The May 7 print was explosive: the stock jumped 78% the next day and held more than 54% of that over the following week. But the May 14 release — just seven days later — reversed sharply, with the stock falling 6% on the day and 8.6% over the week that followed. Two data points is a thin sample, but the pattern suggests the market can swing violently in either direction.

The August 6 print is therefore less about whether Fluence can grow and more about whether the backlog conversion narrative and any data centre contract update can justify a stock trading at 240x earnings with short sellers still committed at 20% of float.
