In this episode of Run the Numbers, CJ Gustafson talks with Rivian CFO Claire McDonough about financing one of the most capital-intensive businesses in the world. They cover long-term investment decisions, capacity planning, cash management as production scales, lessons from Rivian’s nearly $14B IPO, the risks of over- and under-building, and why federal EV tax credits matter more than most people think.
