Rocket Lab’s backlog, vertical integration and Iridium optionality are exceptional, but a 65.64x P/S multiple leaves little room for execution misses.
Overview
Rocket Lab is a vertically integrated space contractor spanning Electron and HASTE launch services, Neutron development, satellite components, buses and prime mission integration. Space Systems is becoming the economic center of gravity: Q2 2026 product revenue nearly doubled to $181.35M and represented 77.5% of consolidated revenue. **Q2 revenue reached a record $234.07M, up 61.98% year over year, while backlog rose 137% to $2.36B.** Cash and equivalents were $2.13B, supported by $1.53B of first-half ATM proceeds, but the planned $8.0B Iridium acquisition introduces a $3.6B secured bridge facility and materially changes financial risk. The strategic upside is substantial: Iridium would add 66 satellites, L-band spectrum, 2.55M subscribers and a recurring communications platform, while Neutron could expand launch capacity into medium lift. Nevertheless, the stock closed at $82.83 with a 65.64x trailing P/S multiple versus a 21.31x historical median and 8.74x peer average. **The central investment issue is not operational capability but whether future growth can justify an already extreme valuation.** Near-term catalysts are Neutron pad delivery targeted for Q4 2026, Archimedes qualification, Iridium closing in mid-2027 and continued defense backlog conversion.
