Fluence Energy, Inc. (NASDAQ: FLNC) saw its stock price plummet 14.86% in after-hours trading following the release of its second-quarter financial results 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 with a net income loss of $41.9 million.

The primary drivers behind the stock's sharp decline appear to be Fluence's revised guidance and weaker-than-expected order intake. The company lowered its fiscal year 2025 adjusted EBITDA guidance to a range of $0 to $20 million, down from previous projections. Additionally, Fluence reduced its total fiscal year 2025 revenue expectations to a range of $2.6 billion to $2.8 billion, citing ongoing economic uncertainty in the U.S. market and evolving trade and tariff landscapes. 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 has clearly rattled investors, leading to the significant after-hours sell-off.
