Rocket Lab Scales Space Infrastructure Amid Valuation Concerns

Rocket Lab (RKLB) has seen its market valuation surge nearly 250% over the last year, with shares climbing from approximately $21 to over $73. This rally is underpinned by a period of aggressive growth and a diversifying business model that extends beyond simple launch services. The company is transitioning into an end-to-end space systems firm, with its satellites and spacecraft segment now accounting for roughly 67% of total revenue. The primary catalyst for future growth is the upcoming Neutron medium-lift rocket, which is designed to compete directly with SpaceX's Falcon 9 at a price point approximately $15 million lower per launch. Financial performance in 2025 showed significant momentum, with record revenue of $602 million, representing a 38% year-over-year increase. The company's backlog surged 73% to nearly $1.9 billion, supported by a $816 million contract from the Space Development Agency. Operationally, the firm maintained a 100% success rate across 21 missions last year. However, the stock's rapid ascent has led to a rich valuation, with shares trading at approximately 66 times sales. Rocket Lab continues to operate in the red, posting a loss of nearly $200 million against its $602 million in sales. While margins are improving, the company's valuation heavily prices in the successful deployment of the Neutron rocket, leaving investors exposed to significant execution risk.
