Harbinger raises $240M to fund FedEx truck ramp and new defense work
The Garden Grove EV builder must deliver 2,000 Class 4-6 trucks to FedEx by end of 2027 while expanding into energy storage, power generation, and Army vehicle platforms.
Harbinger raised $240 million in Series D funding to ramp production for a 2,000-truck FedEx order while pushing its electric vehicle platform into energy storage, power generation, and defense. Tiger Global, Capricorn's Technology Impact Fund, and Ridgeline co-led the round, the Garden Grove, California, company said Thursday.
How many trucks does Harbinger need to build for FedEx?
The FedEx order, valued at more than $300 million, calls for 2,000 Class 4 through Class 6 electric delivery trucks by the end of 2027. Harbinger said in September it had finished its 1,000th vehicle. The FedEx contract alone requires twice that production volume in 14 months.
Harbinger builds Class 4 through Class 6 chassis in all-electric and plug-in hybrid versions and designs its own powertrain, battery system, steering, and brakes. Its HC Series Cab, unveiled in March, adds a gasoline range extender good for up to 500 miles, depending on configuration, and up to 15 kilowatts of exportable power so crews don't need a separate generator.
What else is Harbinger building besides trucks?
The company is building the platform for an uncrewed Army supply vehicle under an American Rheinmetall contract, its first defense deal. It has also started selling its batteries for energy storage. The release did not name any energy storage or power generation customers. The Army program is in a prototype phase that typically runs three to 10 units, and no contract value has been disclosed.
Harbinger also acquired autonomy software maker Phantom AI. The release describes Harbinger as "an American industrial technology platform company" and lists commercial vehicles as one of five markets the new funding covers.
"Electrification is at the core of everything we do, and increasingly, electrification is at the core of industry, defense, mobility, and AI," said John Harris, Harbinger's co-founder and CEO.
Who invested in the Series D round?
Fidelity Management & Research Company, Squarepoint Capital, and Xantium joined as crossover investors. Maniv and Greycroft returned from prior rounds. FedEx and THOR Industries came in as strategic investors through TechNexus. Paul Melander, FedEx's senior vice president of safety and transportation, recently joined Harbinger's board. Goldman Sachs and Morgan Stanley served as placement agents.
BuildGroup, named as a strategic investor in data centers, also took part. Tiger Global tied its investment to the AI buildout. "Harbinger excels at electrification, and electrification has become one of the most pressing bottlenecks of the AI era," said Griffin Schroeder, a partner at Tiger Global.
The Series D follows a $160 million Series C last November, when FedEx placed an initial order for 53 trucks. Harbinger said it has raised more than $650 million since its 2021 founding. Harris told Bloomberg News the company has focused on bringing in investors that are "generally crossover or public markets focused." The release did not disclose Harbinger's valuation, its current production capacity, or how the new money splits between trucks and the newer businesses.
Where does Harbinger fit in the medium-duty EV market?
Zero-emission trucks reached a record 4.14% of U.S. truck deployments in the second half of 2025, according to CALSTART's June 2026 Zeroing in on Zero-Emission Trucks market update, as total truck sales fell 35% year over year. Cargo vans supplied 12,158 of the 12,996 new units. Every other segment, including medium-duty step vans and trucks, added 838. Harbinger's Class 4 through Class 6 trucks fall in that group.
The company plans to carry the in-house engineering behind its trucks into each new market. "Harbinger's role is not simply to give customers another option," Harris said. "It is to reset expectations for what critical systems should deliver."
What this means for fleets pricing medium-duty EVs
Fleets pricing medium-duty electric delivery trucks now have a builder backed by Fidelity, Tiger Global, and FedEx itself, with $240 million in fresh capital. The FedEx order for 2,000 Harbinger EVs will show whether that backing turns into trucks at scale. Harbinger's ability to double its lifetime production in 14 months while launching defense and energy storage businesses is the open question. The HC Series Cab's 500-mile range extender and 15-kilowatt exportable power address two medium-duty pain points (range anxiety and jobsite generator cost), but only if the units ship on time and hold up in service.
