What Is This Lawsuit About? The lawsuit alleges that Fluence Energy made false and/or misleading statements and failed to disclose that: (i) the Company’s ability to deliver its backlog and recognize the revenue underlying its fiscal 2026 guidance depended on new contract manufacturing facilities, including facilities that were not complete, not operational, and/or not capable or producing at the volumes the guidance assumed; (ii) the corrective measures the Company had implemented to address production problems at its contract manufacturers were not remediating those problems, which persisted and extended to the Company’s new facilities; and (iii) as a result, a material portion of the backlog that Defendants represented as “securing” or “covering” the Company’s fiscal 2026 revenue guidance were likely to be delivered and recognized in fiscal 2026.

On February 4, 2026, Fluence Energy reported its first quarter 2026 financial results, revealing a GAAP gross profit margin of approximately 4.9%, down 6.5 percentage points year-over-year, due to “additional estimated costs on two projects.” Additionally, the Company reported that its net losses increased to $62.6 million, compared to a net loss of $57 million for the same quarter the previous year. On this news, the price of Fluence Energy shares declined by $10.04 per share, or approximately 34.63%, from $28.99 per share on February 4, 2026 to close at $18.95 on February 5, 2026.

Then, on August 5, 2026, the Company announced its third quarter 2026 financial results, revealing revenue of $6.49.8 million, which was “weaker than expected, primarily reflecting production delays at new contract manufacturing facilities,” and gross profit margin of 5.9%, compared to approximately 15.4% in the same quarter last year, “reflecting the impact of delays to revenue.” Fluence Energy also announced that it “now expects that $400.0 million in project deliveries will be delayed into fiscal 2027 due to production issues at a new international contract manufacturing facility and construction related delays that affected the completion and start-up of a new U.S. contract manufacturing facility.” The Company reduced its guidance as a result, cutting its fiscal year 2026 revenue guidance by $0.4 billion at the midpoint and its adjusted EBITDA guidance by $60 million at the midpoint, a negative 120% change. On this news, the price of Fluence Energy shares declined by $1.02 per share, or approximately 7.17%, from $14.23 per share on August 5, 2026 to close at $13.21 on August 6, 2026.

Finally, on September 16, 2026, Fluence Energy announced a mid-quarter guidance update, revealing that the Company was cutting its full year revenue guidance by approximately $0.6 billion, to $2.4 billion. Fluence Energy also cut its full year adjusted EBITDA guidance from negative $10 million to negative $200 million. The Company attributed these guidance cuts to ongoing “delays in the ramp-up of our contract manufacturing facility.” On this news, the price of Fluence Energy shares declined by $1.39 per share, or approximately 15.36%, from $9.05 on September 16, 2026 to close at $7.66 on September 17, 2026.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Courts do not consider lead plaintiff applications submitted after the relevant deadline. If you choose to take no action, you may remain an absent class member. Learn more about the lead plaintiff process and eligibility requirements here. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
