Rocket Lab Corp (NASDAQ:RKLB) shares are rising Thursday morning as traders digest the Iridium deal narrative and what it could mean for Rocket Lab’s push into recurring satellite-connectivity revenue.

• Rocket Lab stock is building positive momentum. Why is RKLB stock trading higher?

What Is Rocket Lab’s Iridium Acquisition Catalyst?

Rocket Lab’s proposed cash-and-stock acquisition of Iridium Communications values Iridium at about $8 billion, with Iridium shareholders set to receive $27 in cash plus Rocket Lab shares, and both boards unanimously approving the transaction.

The companies are targeting a mid-2027 close, pending shareholder and regulatory approvals, and Rocket Lab has lined up a $3.6 billion bridge loan from Deutsche Bank and Wells Fargo to help fund the cash portion.

Rocket Lab has also been leaning on execution wins that keep the "full-stack" pitch credible, including the Space Force’s VICTUS HAZE mission where Electron launched 16 hours and 42 minutes after the order and the Pioneer spacecraft was commissioned in 38 hours.

Rocket Lab Stock: Critical Levels To Watch

From a trend perspective, RKLB is still in a longer-term uptrend (up 112.95% over the past 12 months), but the intermediate tape is trying to stabilize after a pullback from the May swing high and 52-week high at $151.00. At $86.14, the stock is trading 12.7% below its 20-day SMA ($98.28) and 19.8% below its 50-day SMA ($107.04), while sitting 12.2% above its 200-day SMA ($76.46).

MACD is the cleaner momentum read right now: it’s below its signal line and the histogram is negative, which points to upside pressure cooling versus the prior upswing unless buyers can rebuild momentum. That lines up with the bearish 20-day SMA below the 50-day SMA, even as the longer-term 50-day SMA above the 200-day SMA keeps the bigger-picture structure constructive.

• Key Resistance: $93.00 — a nearby round-number area that also sits close to the 100-day SMA ($89.31), where rebounds can start to stall if follow-through is weak
• Key Support: $80.00 — a nearby round-number level above the 200-day SMA ($76.46), where buyers may try to defend the longer-term trend

What Is Rocket Lab’s Business Model?

Rocket Lab is a space company that builds rockets and spacecraft, offering end-to-end mission services for civil, defense, and commercial customers. It designs and manufactures the Electron and Neutron launch vehicles and the Photon satellite platform, with operations spanning Launch Services and Space Systems.

In the context of the Iridium tie-up, the strategic pitch is about moving beyond "launch + build" into more of the value chain—especially recurring connectivity revenue tied to constellation operations and services. That matters because Iridium brings globally licensed L-band spectrum, a 66-satellite low-Earth-orbit network with pole-to-pole coverage, 2.55 million subscribers, and more than 500 channel partners.
