Rocket Lab flags weaker quarterly margins as lower-profit satellite sales increase

Rocket Lab said quarterly margins are weakening as a larger share of its sales comes from lower-profit satellites. The headline does not provide a new revenue, margin, or outlook figure for the quarter, so the size and duration of the pressure are not quantified.

The update matters because it challenges the profitability profile behind Rocket Lab's growth story. Finnhub enrichment shows FY2025 revenue of $601.8M, up 38.0% year over year, alongside a 34.4% gross margin, a -32.9% net margin, and diluted EPS of $-0.37.

That combination leaves the company exposed to a sharper valuation reaction if lower-margin satellite revenue continues to expand without operating leverage. The bull case is that the added sales support the top-line trajectory and can eventually improve scale, while the bear case is that growth is coming with weaker economics and continued losses.

The next read-through is the company's detailed quarterly margin commentary, including the mix of satellite versus other revenue and any change to its profitability outlook. Until those figures are available, the headline establishes direction but not the magnitude of the earnings impact.
