Harbinger Lands $240M Series D to Push EV Platform Beyond Trucks

Harbinger has raised $240 million in a Series D round co-led by Tiger Global, Capricorn's Technology Impact Fund, and Ridgeline, money the Garden Grove, California company will use to push its electric vehicle platform into energy storage, power generation, autonomy, and defense. The round, announced Thursday, lands while the company ramps production for a 2,000-truck order from FedEx valued at more than $300 million, with deliveries due by the end of 2027.

The scale of the task is stark. CEO and co-founder John Harris told Bloomberg News in September that Harbinger had just finished its 1,000th vehicle. The FedEx order alone calls for twice that many trucks within roughly two years.

What does the new money fund?

The release describes Harbinger as "an American industrial technology platform company" and lists commercial vehicles as one of five markets the new funding covers. Alongside the truck ramp, the capital will bankroll newer lines of business in energy storage, power generation, autonomy, and defense.

"Electrification is at the core of everything we do, and increasingly, electrification is at the core of industry, defense, mobility, and AI," Harris said in the release.

The company builds Class 4 through Class 6 chassis in all-electric and plug-in hybrid versions, designing 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, plus up to 15 kilowatts of exportable power so crews don't need a separate generator. Harbinger also acquired autonomy software maker Phantom AI.

Its first defense deal came this summer: the company is building the platform for an uncrewed Army supply vehicle under an American Rheinmetall contract. That program sits in a prototype phase that typically runs three to 10 units, and no contract value has been disclosed. Harbinger has also begun selling its batteries for energy storage, Bloomberg News reported, though the release named no energy storage or power generation customers.

Who invested, and why?

The Series D follows a $160 million Series C last November, when FedEx placed an initial order for 53 trucks. Harbinger has now raised more than $650 million since its founding in 2021.

Fidelity Management & Research Company, Squarepoint Capital, and Xantium joined as crossover investors, while Maniv and Grevcroft returned. Harris told Bloomberg News the company focused on bringing in investors that are "generally crossover or public markets focused." 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 in the release as a strategic investor in data centers, also participated, and 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.

Where do medium-duty EVs stand?

The market context is uneven. 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, even as total truck sales fell 35% year over year. Cargo vans supplied 12,158 of the 12,996 new units, while every other segment, including medium-duty step vans and trucks, added just 838. Harbinger's Class 4 through Class 6 trucks sit squarely in that smaller group.

The release did not disclose Harbinger's valuation, its current production capacity, or how the new capital splits between trucks and the newer ventures. The company said it 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."

For fleets pricing medium-duty electric delivery trucks, the pitch is now a builder backed by Fidelity, Tiger Global, and FedEx itself, with $240 million in fresh capital. Whether that backing converts into trucks at scale will show in the FedEx delivery count through 2027.
