Harbinger raises $240M Series D to expand into defense and storage

Crossover backers like Fidelity signal the electric truck maker is positioning itself for a near-term IPO.

• Harbinger raised $240 million in a Series D round co-led by Tiger Global, Capricorn's Technology Impact Fund, and defense-focused firm Ridgeline, pushing total funding past $650 million since its founding.
• Harbinger builds Class 4-6 electric and plug-in hybrid truck chassis with its own powertrain, battery system, steering, and brakes, and has acquired autonomy software maker Phantom AI.
• FedEx, which led Harbinger's $160M Series C last year, returned as an investor and recently placed a separate order for 2,000 trucks worth more than $300 million, due by end of 2027.
• Harbinger is now building an uncrewed Army supply vehicle under a contract with American Rheinmetall and has started selling its EV batteries for grid-scale energy storage.
• Fidelity Management & Research, Squarepoint Capital, and Xantium joined as crossover investors, a group CEO John Harris says reflects the company curating a cap table for pre-IPO positioning.
• At $240 million, the round ranks above the 94th percentile of all-time U.S. Series D rounds in the energy sector, per Dealroom's analysis of 210 comparable deals.
• Harbinger's pivot from a single electric truck chassis into defense, storage, and autonomy illustrates how commercial EV startups are diversifying revenue streams to survive a tough standalone EV market.
