Bret Johnsen Biography

Bret Johnsen is the chief financial officer of SpaceX, an aerospace company founded by Elon Musk. As the company's longest-serving and only CFO, Johnsen oversees SpaceX's long-term financial development and internal financial operations. He holds a bachelor's degree in accounting from the University of Southern California and a master's degree in finance from San Diego State University.

Johnsen began his career in junior finance roles at Qualcomm and at the accounting firm Coopers & Lybrand. He later served as corporate controller at Classified Ventures, the joint venture that operated Cars.com and Apartments.com, before joining semiconductor company Broadcom. At Broadcom, Johnsen advanced from controller for several business groups to vice president, corporate controller, and principal accounting officer, overseeing an accounting organization spanning nine countries.

After Broadcom, Johnsen was senior vice president and chief financial officer for Mindspeed Technologies, where he was recognized by Orange County Business Journal for guiding the company through a recession by implementing cost reductions, restructuring debt, selling stock, and raising capital through patent sales. Johnsen joined SpaceX after being approached by the company, bringing experience in financial management for high-growth technology companies.

At SpaceX, Johnsen has overseen the company's expansion into launch services, satellite internet, communications, and artificial intelligence infrastructure. Under his financial leadership, SpaceX became the lowest-cost provider per kilogram to space in the industry, while Starlink grew to serve more than 10 million customers in over 160 countries with a constellation of more than 10,000 satellites. Johnsen played a key role in SpaceX's initial public offering, which valued the company at approximately $1.77 trillion and raised about $75 billion in gross proceeds. He also managed SpaceX's merger with xAI, Musk's artificial intelligence company, in an all-stock transaction valued at $1.25 trillion.

Following the IPO, Johnsen reported that SpaceX was on pace to reach $100 billion in annualized recurring revenue. Industry analysts have noted Johnsen's approach to financial disclosure, capital allocation, and risk management as influential for CFOs guiding founder-controlled, multi-business companies into the public markets. Johnsen has shared insights on innovation and financial leadership at forums such as a Dean's Dialogue at USC's Marshall School of Business, discussing emerging technologies, radical innovation, and the value of business education.
