Fluence revenue up 154% but margin halves in last three months of 2025

System integrator Fluence saw revenue of US$475.2 million in the last quarter of 2025, while its net loss grew around 10% to US$62.6 million.

The battery energy storage system (BESS) technology and services firm released its results yesterday (4 February), covering the three months ending 31 December, 2025. That period is Fluence’s Q1 2026 because its financial year runs to 30 September.

Revenue was up 154.4% year-on-year though its GAAP-adjusted gross profit margin halved, from 12.5% in Q1 2025 to 4.9% in Q1 2026 (5.6% adjusted gross profit margin). It said there were additional estimated costs on two projects, totalling US$20 million, which it mostly expects to recover over the year.

Net loss subsequently grew, up around 10% to US$62.6 million, while its EBITDA loss increased by around 5% to US$52.1 million.
