Form 144 is filed by Rocket Lab USA Inc. officer Adam C. Spice (COO) on January 5, 2026, disclosing intent to sell 1,365,665 shares of common stock through Morgan Stanley, with aggregate market value of $103,776,883.35 based on 534,156,333 shares outstanding. The securities include 731,330 shares acquired same-day via cash exercise of stock options and 634,335 from a prior exercise on Sep 18, 2025. This represents ~0.26% of outstanding shares. The transaction relies on a Rule 10b5-1 trading plan adopted Sep 19, 2025, mitigating concerns of opportunistic timing. Spice discloses recent sales on Nov 24 and 22, 2025, totaling 62,627 shares for $2,545,894.61. He certifies no knowledge of undisclosed material adverse information about Rocket Lab. In context of Rocket Lab's space launch business, such filings are common for executives monetizing equity compensation amid growth, but warrant monitoring for liquidity signals.

For RKLB investors, this pre-planned 10b5-1 sale by COO Spice provides liquidity from option exercises without signaling distress or adverse knowledge. The $104M volume is notable but minor relative to ~$534M shares o/s and market cap; potential short-term selling pressure on NASDAQ: RKLB. Strategically neutral for Rocket Lab's launch operations. Monitor actual execution, post-sale ownership (via Form 4), and any clustered insider activity.
