Rocket Lab Posted Record Sales And A Larger Backlog

Revenue for the quarter reached $268 million, a figure management called a record and a 72.7% increase from a year earlier. The total topped analyst expectations of $257.2 million and came in above the company’s own guidance of $250 million to $265 million.

The company’s loss widened, however. Rocket Lab posted a GAAP loss of $0.12 per share, compared with $0.08 in the second quarter. Management attributed the increase mainly to costs tied to its pending purchase of Iridium.

Signed orders also rose sharply. Backlog, representing the value of contracts not yet delivered, reached about $3.6 billion at the end of the quarter, up 52% from the end of June. Part of that total came from Neutron, a rocket Rocket Lab has not yet flown. The company signed eight Neutron launches in the quarter worth roughly $515 million, selling several at a new base price of $70 million a launch. Management also said Neutron’s first launch has moved to 2027, after voids were found in a propellant tank.

The Industrials Fund Slipped While Rocket Lab Rose

Rocket Lab recorded its gain as broader markets retreated. XLI, the fund that tracks the industrials sector, slipped 0.1%, and the Nasdaq Composite fell 0.7% on a day when a hot October inflation report rattled markets.

Three of the five companies on Rocket Lab’s Trefis peer list rose, with Lockheed Martin leading the group at 2.5%. That advance was well under half of Rocket Lab’s gain, while Planet Labs and Redwire both edged lower.
