Rocket Lab (NASDAQ: RKLB) has emerged as a compelling industrial investment for 2026, bolstered by its pending acquisition of Iridium Communications and a rapidly expanding space infrastructure footprint.
The deal to acquire Iridium Communications promises to transform Rocket Lab into a genuine space powerhouse, combining its proven launch technology with Iridium’s extensive communications spectrum assets.
Analysts suggest the combination could position Rocket Lab as a serious competitor to SpaceX, a remarkable trajectory for a company that began as a small-payload launch specialist.
Rocket Lab is also closing in on reusable rocket technology, the same innovation SpaceX leveraged to dramatically lower launch costs and undercut competitors on price.
The combined Rocket Lab-Iridium business is projected to generate $1.8 billion in revenue in 2026 and come close to breaking even on a profit basis, giving the merged entity a price-to-sales ratio in the mid-30s.
On a standalone basis, Rocket Lab’s price-to-sales ratio appears elevated, but that figure becomes considerably more reasonable when Iridium’s revenue contribution is factored into the calculation.
Caterpillar (NYSE: CAT), the revered heavy equipment manufacturer, is benefiting from the artificial intelligence data center boom, which has driven strong demand for its power generation products and construction machinery.
Analysts’ consensus for Caterpillar’s full-year fiscal 2026 calls for 13% sales growth to $76.6 billion, with net income expected to jump approximately 25% to $11.2 billion.
Caterpillar converts its revenue into billions in free cash flow, a level of financial maturity that stands in stark contrast to Rocket Lab, which continues to burn cash as it scales its operations.
Caterpillar’s forward price-to-earnings ratio appears a little pricey, and macroeconomic headwinds could mean 2026 demand does not prove as robust as street expectations currently suggest.
Technical risks remain a persistent concern for Rocket Lab, as recent launch aborts have demonstrated the potential for delays in revenue recognition at critical moments.
Caterpillar is also highly sensitive to the broader economic cycle, with demand fluctuating considerably based on global infrastructure spending levels and shifts in commodity prices.
Considering the long growth runway available for space-based operations and the strategic logic of the Iridium combination, Rocket Lab stands out as the stronger stock to own heading through 2026.
