Rocket Lab shares ended modestly higher on Tuesday after giving up an early run-up, as year-end trading kept the space and defense supplier volatile.
The stock closed up 0.47% at $70.45, and was up 0.08% at $70.50 in after-hours trading, when stocks trade after the 4 p.m. ET close. FinancialContent+1
The move matters because Rocket Lab has become a high-beta proxy for U.S. defense-space spending and commercial launch demand, after a sharp late-December rally that pushed it near its 52-week high. FinancialContent
That rally has been fueled by investor focus on the company’s expanding satellite manufacturing work and expectations for key 2026 milestones, including its next-generation Neutron rocket. Nasaspaceflight
On Tuesday, Rocket Lab traded between $70.44 and $74.69 after opening at $73.03, according to market data. FinancialContent

In mid-December, Rocket Lab said it won an $816 million prime contract from the U.S. Space Development Agency to design and manufacture 18 satellites for the agency’s Tracking Layer Tranche 3 program. Rocket Lab
“The Tranche 3 Tracking Layer constellation is part of the U.S. Space Force’s strategy to counter rapidly evolving global threats,” founder and CEO Peter Beck said. Rocket Lab
Reuters reported the Space Development Agency reached agreements with four suppliers — Lockheed Martin, L3Harris Technologies, Northrop Grumman and Rocket Lab — to build 72 infrared satellites worth about $3.5 billion, with launches expected in 2029. Reuters
Rocket Lab has also highlighted its launch cadence. The company said it finished 2025 with 21 Electron launches and 100% mission success, and that its next Electron launch is slated for early in the first quarter of 2026. Rocket Lab
Investors are also tracking Neutron, which would move Rocket Lab into a larger launch segment. NASASpaceFlight.com reported Neutron’s debut is targeted no earlier than mid-2026, with the first flight vehicle expected to ship to Wallops Island in the first quarter of 2026. Nasaspaceflight
Traders heading into Wednesday’s session are watching whether shares hold the $70 area and whether the stock can retest the $79.83 52-week high, after the latest after-hours range ran from $70.12 to $70.85. FinancialContent+1
One risk in focus is execution on fixed-price defense contracts, which typically put cost overruns on the contractor. Reuters said the SDA contracts were fixed-priced. Reuters
