Equity comp at Boom Supersonic

• Aerospace certification timelines (Overture FAA cert targeted late 2020s, Symphony engine in-house development) mean RSU grants typically face 7-10+ year horizons between initial vest and liquidity event, materially longer than tech pre-IPO norms. Seven-year post-termination exercise windows for options are common at capital-intensive deep-tech firms to offset this.
