Why did fixed-price contracts cause Proterra's bankruptcy?

Transit agencies require fixed-price bids to manage budgets. Proterra would bid on a bus order at a specific price, then build and deliver the buses 12-18 months later. When component costs (batteries, semiconductors, steel) surged 20-40% during that window due to supply chain disruptions and inflation, the company earned less per bus than its manufacturing costs.

Did Proterra have government support?

Yes — Proterra had strong support from the Biden administration's EV transition initiatives and received federal funding through transit grants. Its buses were deployed by transit agencies receiving federal electrification funding. The bankruptcy was particularly painful given this federal backing.

Who acquired Proterra's business after bankruptcy?

Proterra's bus manufacturing division was acquired by a consortium that included Daimler Truck North America, which continued producing Proterra-branded buses. The energy systems business (charging infrastructure and technology) was separately sold to another acquirer.

Was Proterra making real commercial progress before bankruptcy?

Yes — Proterra was genuinely commercially established, having delivered over 1,000 electric buses to transit agencies across the US. This distinguishes it from EV frauds like Nikola; Proterra's bankruptcy was a financial structure failure, not a product or technology failure.

Proterra

"America's leading electric bus maker — backed by Amazon, Daimler, and the Biden administration — bankrupt in August 2023 when component shortages and fixed-price contracts created an unsurvivable cost squeeze."

// Fatal mistake: Fixed-price government contracts signed during low-inflation periods became catastrophically loss-making when semiconductor shortages, steel prices, and labor costs surged 20-40% in 2021-2022 — with no contract renegotiation rights.
