Rocket Lab Stock Closes Up 10.9% at $58.86 on a Day It Filed Third Quarter Results

1What the company reported

Rocket Lab Corp (RKLB) reported record third quarter revenue of $268 million in a results release filed with the SEC at 4:06 p.m. ET on November 9, 2026, after the close. The quarter ended September 30, 2026. The release prints its tables in thousands of dollars, and the figures below are quoted as printed, each beside the year earlier figure where the release gives one.

• Sales: Total revenue was $267,834 thousand, against $155,080 thousand a year earlier. The company put the rise at 73% year on year.
• Profit: The net loss was $79,677 thousand, against $18,257 thousand a year earlier. The loss per share was $0.12, against $0.03.
• Adjusted profit: Adjusted EBITDA, a profit measure the company builds by leaving out interest, taxes, the gradual cost of equipment and other items it calls unrepresentative, was a loss of $18,047 thousand. A year earlier it was a loss of $26,275 thousand.
• One time items: The quarter included a loss on extinguishment of debt of $27,259 thousand, a charge for retiring debt, with none a year earlier. It also included transaction costs of $21,340 thousand, the fees tied to deals, against $5,118 thousand a year earlier.
• Cash and backlog: Cash flow from operations, the cash the business generated by running, was positive at $7.2M. Backlog, which is orders signed but not yet delivered, reached $3.57 billion, up 52% since the end of the second quarter.
• Guidance: Guidance is the company's own outlook for a coming period. For the fourth quarter it gave revenue of $270 million to $290 million, and adjusted EBITDA loss of between $14 million and $20 million. It gave gross margin, the share of sales left after direct costs, of 34% to 36% under standard accounting rules, and 39% to 41% after its own adjustments. The release prints no earlier range, so this note cannot say whether guidance changed.
