Our presenters today are Rocket Lab founder and chief executive Peter Beck and chief financial officer Adam Spice. After our prepared comments, we will take questions. And now let me turn the call over to Mr. Beck.

Thank you, Marielle, and thank you, everybody, for joining us today. We've got a lot of great achievements and milestones to share on our start to the year, not the least of which is executing a record number of launches and space systems growth that delivered a record total revenue of $93 million in the quarter, up 55% quarter over quarter and 69% year over year. Adam will talk through the rest of the details of our financial results for the first quarter before covering the financial outlook for Q2 2024. After that, we'll take some questions and finish today's call with the near-term conferences we'll be attending. All right, on to what we achieved in the first quarter of the year, starting with Electron. We had a great series of launches in Q1 with four successful missions, three of them for commercial customers from Launch Complex 1 in New Zealand, and a national security mission for the NRO out of our second site in Virginia. We had a launch turnaround of just eight days between our flight for the Japanese Customs Inspector and the NRO launch, which was no small task from two launch sites across the world. In fact, we remain the only company with the capability of orbital launch from both hemispheres. It really demonstrates the capability of the team to turn around launches so quickly and sets us up well to execute against our pact manifest for 2024. We completed our fifth launch of the year less than two weeks ago, a commercial mission for CASE Institute of South Korea, along with a landmark scientific mission for NASA to test our solar sailing technology also on board. No two rideshare missions are the same, and this launch in particular was a tricky and complex one that played into our unique strength. For large launch rides here, normally you have a bunch of satellites that are heading to the exact same orbit, and you deploy them into one location. If the orbit isn't ideal from your spacecraft, then you're kind of tough like. But for CASE and NASA, we had two satellites going to two completely different orbits to each other. First, one to 520 kilometers, and then all the way up to 1,000 kilometers in low orbit for the other. Those kinds of conflicting mission requirements would normally require two separate launches, but with our unique kick-stage capabilities, we're able to drop KAIST off at 520 and NASA up to 1,000, and then complete another series of engine burns to bring the kick-stage back closer to Earth for faster disposal and demisability. It's this kind of precision and flexibility that makes us a really attractive launch service for our customers, which is also inherent in the next two missions we have scheduled to fly in Q2. So coming up in Q2, we have two back-to-back missions scheduled for NASA to deliver their pre-fire mission to space, or missions to space. The mission is focused on understanding how much of Earth's heat loss is lost into space from the Antarctic and Arctic, which will help improve climate change models and

provide better predictions on sea level rise and weather changes in the future.
