• The announcement comes shortly after Rocket Lab completed its first dedicated launch for the European Space Agency over the weekend.

Shares of Rocket Lab USA Inc. (RKLB) edged about 0.9% higher in Monday’s post-trading hours after the company announced that it had received regulatory approval to acquire space laser optical communications company Mynaric AG, marking its first European footprint.

Rocket Lab said in a statement that the transaction had been approved by Germany’s Federal Ministry for Economic Affairs and Energy. It added that it expects the transaction to close in April.

RKLB shares closed down by 5.8% on Monday amid a broader market selloff.

Transaction Rationale

Mynaric’s acquisition is set to strengthen Rocket Lab’s position as a full-service space company, enhancing its capabilities in launch, spacecraft manufacturing, and satellite components.

Laser communication, which is critical for satellite constellations due to its high data speeds, security, and scalability, has faced supply and cost challenges. Rocket Lab aims to address this by scaling Mynaric’s optical terminal production, leveraging its track record of making space components more accessible, the company said.

The deal also establishes Rocket Lab’s first European base in Germany. Mynaric already supplies terminals for Rocket Lab’s SDA satellite contracts, and the company plans to improve production efficiency, reliability, and delivery timelines for customers.

“We’re an exciting step closer to expanding our ability to support the German and European space industry at a much greater level,” said Rocket Lab founder and CEO Sir Peter Beck.

The announcement comes shortly after Rocket Lab completed its first dedicated launch for the European Space Agency (ESA) over the weekend.

Rocket Lab also said that Mynaric will continue to be headquartered in Munich, Germany, after the deal, helping it expand its ability to support German and broader European space programs.
