Shares were acquired on 09/06/2022 via restricted stock vesting under a registered plan in exchange for services rendered to the issuer. Aggregate market value is $1,277,475 based on current pricing, against 499,911,078 shares outstanding. No securities sold by her in the past 3 months. Saintil certifies no knowledge of material adverse non-public information regarding Rocket Lab's operations. This filing relates to Rocket Lab's executive compensation practices, where RSUs vest over time to align incentives with performance in the competitive space launch sector.

Routine insider sale of vested RSUs by director Saintil represents minor liquidity event (~0.01% of shares outstanding), unlikely to materially impact stock price. Affirms confidence in no adverse info, aligning with standard compensation practices at growth-stage space firm like Rocket Lab. Investors should monitor aggregate insider activity and upcoming earnings for business momentum, but this isolated filing poses low near-term risk.
