Rocket Lab USA (RKLB) shares fell sharply after reports of a strategic partnership with Meta were debunked. The false rumor erased speculative gains that had accumulated prior to the correction.

Investor caution ahead of the Q1 2026 earnings release further amplified the decline. Selling pressure also intensified due to Rocket Lab's existing $1 billion at-the-market equity program. Potential shareholder dilution remains a primary concern for the market.
