Fluence Energy Craters After Second Guidance Cut in Four Months

Fluence Energy just told investors, for the second time this year, that its numbers were too optimistic — and the market punished it hard.

Shares of the battery storage company slumped 18% after-hours Wednesday after Fluence slashed its fiscal 2026 guidance again. Revenue is now expected around $2.4 billion, down from a prior midpoint near $3 billion. The stock touched roughly $7.30 in the aftermarket session, down from a $9.05 close, and is now off 54% year-to-date.

The company also now expects an adjusted EBITDA loss of about $200 million — a dramatic swing from the roughly $10 million loss midpoint it had guided to as recently as early August.

Wall Street wasn't braced for a cut this steep. Analysts polled by Fiscal AI had been modeling $2.98 billion in revenue and just a $15.7 million EBITDA loss — nowhere near where Fluence just landed.

The culprit, according to reporting picked up by Stocktwits, is a familiar one: Fluence's Houston contract manufacturing facility, meant to produce battery enclosures domestically, is still behind schedule on construction and automation. That plant has now derailed guidance twice — first in August, when delays pushed roughly $400 million of expected sales into fiscal 2027, and again this week.

Fluence's second guidance cut this year erased more than $400 million in expected revenue and swung its EBITDA outlook from near-breakeven to a $200 million loss.

The timing isn't a coincidence. Just a day before the guidance cut, Fluence overhauled its leadership — a filing covered by TipRanks shows the board installed AES veteran Bernerd Da Santos as Chief Operating Officer and added AES CFO Stephen Coughlin to the board, while removing Chief Product Officer Peter Williams. AES, a major Fluence shareholder, exercised its nomination rights to force the changes.

That's a governance signal worth watching closely: when a key shareholder pushes leadership changes right before a guidance miss, it usually means the board lost confidence in execution before the public numbers came out.

UBS had already moved ahead of this news, downgrading Fluence to Sell from Neutral and cutting its price target to $8 from $22 — implying real downside even from levels the stock had already fallen to before Wednesday's drop.

To be fair to management, the demand backdrop for grid-scale battery storage hasn't weakened. If anything, utility-scale storage orders have been climbing across the industry as renewables penetration increases and grid operators look for ways to smooth out intermittent power.

CEO Julian Nebreda has said demand for battery storage remains strong both domestically and overseas, and that the international supply chain is functioning well — the problem is specifically the U.S. manufacturing ramp. CFO Ahmed Pasha has set a goal of reaching neutral-to-positive operating cash flow in fiscal 2027 without raising outside capital.

For investors, the actionable read here is patience, not a bargain hunt. A stock that's cut guidance twice in four months and just replaced its operating leadership needs to show consecutive quarters of hitting reduced targets before it's investable again.

Watch the next earnings report specifically for Houston plant output metrics — daily production rates are the tell on whether this settles or drags into another cut.

Also worth tracking: any signs the new AES-aligned board members are pushing further operational changes. That could mean more short-term pain before things stabilize, but it could also be the fix that finally gets the Houston ramp back on schedule.

Bottom line: the demand story behind battery storage is intact, but Fluence has proven twice this year it can't yet execute on it — and that's a distinction retail investors chasing the sector can't afford to ignore.
