TLDR

• Rocket Lab stock rose 6.8% in premarket trading Wednesday after passing a key System Requirements Review for the Space Development Agency.
• The milestone advances its ~$816 million contract to deliver missile warning and tracking satellites.
• Total Space Development Agency contract value now exceeds $1.3 billion.
• Cantor Fitzgerald kept its Overweight rating but held its $96 price target — well below the current $143.20 trading price.

Rocket Lab stock climbed 6.8% in premarket trading Wednesday after the company announced it passed System Requirements Review (SRR) for the Space Development Agency’s Tracking Layer Tranche 3 constellation.

The SRR confirms that Rocket Lab’s proposed satellite solution meets the agency’s operational requirements and sets the technical baseline for the program. It’s a key gate in the development process before hardware production begins.

The program is tied to an approximately $816 million contract to deliver satellites capable of missile warning, tracking, and defense. The satellites will be built on Rocket Lab’s Lightning platform, with all major components made in-house.

That includes advanced infrared sensors, solar arrays, avionics, optical terminals, and propulsion systems. The satellites will also carry the company’s Phoenix infrared sensor payload and StarLite sensors, which are designed to protect against directed energy threats.

$1.3 Billion in SDA Awards

The Tranche 3 win builds on Rocket Lab’s earlier ~$515 million Transport Layer-Beta Tranche 2 contract. Combined, the company’s total Space Development Agency awards now exceed $1.3 billion.

That’s a substantial backlog for a company that has been rapidly expanding beyond launch services into satellite production and defense infrastructure.

The stock currently trades at $143.20, near its 52-week high of $146. It has gained 398% over the past year. Market cap stands at $82.9 billion.

Cantor Fitzgerald reiterated its Overweight rating on RKLB following the news but kept its price target at $96 — well below where the stock is actually trading. The firm flagged risks including Neutron rocket delays, regulatory exposure, payload loss, and supply chain disruption.

InvestingPro analysis also flags the stock as potentially overvalued at current levels.

A Busy Few Weeks for Rocket Lab

The SDA milestone caps a busy stretch for the company. On May 26, Rocket Lab completed the acquisition of Motiv Space Systems, now rebranded as Rocket Lab Robotics.

Motiv brings Mars-proven robotics technology to the table, including hardware used on NASA’s Perseverance rover and CADRE lunar rovers. It also adds solar array drive assemblies and antennas to Rocket Lab’s manufacturing portfolio.

On May 21, Rocket Lab was awarded a $90 million contract from the U.S. Space Force’s Space Systems Command to design, build, and operate two geostationary satellites. It’s the company’s first satellite production program for geostationary orbit.

The following day, May 22, Rocket Lab launched a Synspective StriX radar-imaging satellite — its ninth Electron launch of 2026. Synspective is building a constellation of more than 30 radar satellites by 2028.

At its 2026 Annual Meeting, shareholders also approved Edward H. Frank as a Class II director for a three-year term.
