AST SpaceMobile and Vertiv Holdings are two companies in the high-growth space, each offering potential returns for patient investors. In the first half of 2026, their financial trajectories have taken vastly different paths. Vertiv shows a more stable and growing revenue pattern, while AST SpaceMobile remains a volatile, early-stage company. The contrast between these two companies highlights the trade-off between immediate performance and speculative potential.
AST SpaceMobile: High-risk, high-reward model
AST SpaceMobile focuses on establishing a satellite-based cellular broadband network to connect remote regions directly to standard mobile phones. Its mission is to deliver mobile internet to unserved and underserved global markets. However, as of March 31, 2026, the company reported a net income margin of -1,296%, signaling significant financial strain. This performance is a warning for investors expecting returns in the near term.
To support its ambitious growth, AST SpaceMobile raised $1.15 billion through a private offering of convertible senior notes in July 2026. The company also revised its satellite deployment schedule to optimize its launch strategy. Despite this influx of capital, its revenue remains erratic, with no clear path to consistent profitability. AST is investing heavily in infrastructure to realize its vision, but converting those investments into a solid revenue stream is a long process.
Vertiv: Steady and reliable expansion
Vertiv, in contrast, provides critical power management solutions for data centers, communication networks, and industrial applications worldwide. The company has a history of consistent performance and has recently expanded its offerings through the acquisition of ThermoKey and Strategic Thermal Labs. These acquisitions are part of Vertiv’s strategy to better serve AI data centers, a growing market with high demand.
In the quarter ending June 30, 2026, Vertiv achieved a 15% net income margin, continuing its streak of steady 20%+ quarterly revenue growth. This performance reflects a well-established and reliable business model that has allowed the company to grow steadily over time. Looking ahead, Vertiv forecasts revenue to rise from $10.3 billion in 2025 to nearly $22 billion by 2028, and it is trading at a forward P/S multiple of 4.7, compared to AST SpaceMobile’s 13.6. This suggests that Vertiv is currently the more affordable option for investors.
What investors are really betting on
The choice between AST SpaceMobile and Vertiv is not just about picking the best-performing company, but about selecting the most viable growth story for the future. AST SpaceMobile is selling a vision of satellite broadband that could revolutionize internet access globally. Vertiv, meanwhile, is delivering on a more predictable path of steady expansion in the data center market.
For AST to justify its valuation, it must successfully deploy its satellite network. The company is set to launch BlueBird satellites 8, 9, and 10 on August 5. Analysts anticipate that revenue could grow from $71 million in 2025 to over $1.8 billion by 2028. However, competition from companies like Amazon’s Project Kuiper and other players in the satellite broadband market is intensifying. AST must act quickly and deliver high-quality global coverage to stand out.
The big question for investors is whether they are willing to pay a premium for AST’s potential. If the company can match or surpass Vertiv in annual revenue, the returns could be significant. If not, the high price tag may feel like an overreach. Vertiv faces its own challenges, relying heavily on hyperscalers for data center infrastructure. A slowdown in capital spending from these companies could impact its growth.
Ultimately, the decision to invest in either company depends on the investor’s appetite for risk. AST SpaceMobile offers the allure of huge returns if it can execute on its vision. Vertiv, on the other hand, offers a more reliable and predictable path forward. Which one makes the better long-term investment depends on who can maintain steady growth and adapt to a rapidly changing market.
