Mach Industries Doubles Valuation to $3.7B With $600M Series C Extension After June's $300M Raise

Ribbit, Infinite, Bedrock and Sequoia poured $600M into a Series C extension for Huntington Beach-based Mach Industries just three months after its $300M June round, taking the valuation from $1.8B to $3.7B. Mach ships five unmanned platforms — Viper VTOL, Glide strike glider, Stratos surveillance, Dart counter-UAS and Pike long-range munition — and recently bought Exquadrum for $50M to launch its Mach Energetics propulsion arm.
