Fluence Energy, Inc. (NASDAQ: FLNC) saw its stock price plummet 5.99% in pre-market trading on Thursday, following a disappointing second-quarter earnings report and revised guidance for fiscal year 2025. The energy storage technology provider faced multiple headwinds, including missed earnings expectations, lowered full-year projections, and concerns about tariffs impacting US projects.

For Q2, Fluence reported a loss of $0.24 per share, missing analyst estimates of $0.21 and representing a significant decline from the $0.07 loss per share in the same period last year. Despite beating revenue expectations with $431.62 million against the projected $329.65 million, the company's bottom line remained under pressure. More concerning for investors, Fluence lowered its fiscal year 2025 adjusted EBITDA guidance to a range of $0 to $20 million and reduced its total revenue expectations to between $2.6 billion and $2.8 billion, citing ongoing economic uncertainty in the U.S. market.

Adding to the negative sentiment, Fluence reported weaker-than-expected order intake and announced the pause of certain US projects due to tariff uncertainty. CEO Julian Nebreda characterized the outlook as short-term, stating, "Over time, we expect our domestically sourced solutions to benefit from higher tariff levels." However, the immediate impact of these challenges, coupled with the evolving trade and tariff landscape, has clearly rattled investors, leading to the significant pre-market sell-off.
