Archer Aviation vs. AST SpaceMobile: Which Industrials Stock Is a Better Buy in 2026?

Choosing between Archer Aviation Inc (NYSE:ACHR) and AST SpaceMobile Inc (NASDAQ:ASTS) requires weighing the future of urban air mobility against the promise of universal satellite-based cellular connectivity for everyday smartphones.

Archer focuses on electric flight to bypass city traffic, while AST SpaceMobile builds a space-based network to bridge global communication gaps. Both companies represent high-risk, high-reward plays in the industrial stocks and communications space, attracting investors eager to capitalize on disruptive technology early in its commercialization.

Archer designs and develops electric vertical takeoff and landing (eVTOL) aircraft, primarily its flagship Midnight model. Its commercial strategy relies on collaborations with airline operators like United Airlines (NASDAQ:UAL) and infrastructure partners for vertiports. Customer concentration like this adds a layer of risk to the business, though the recent acquisition of Boeing Co (NYSE:BA) subsidiaries Wisk Aero and SkyGrid expands its technological footprint.

For fiscal year 2025, Archer Aviation reported revenue of just $300,000. This early stage revenue was accompanied by a net loss of approximately $618.2 million. This reflects a company still in its pre-commercial phase as it pursues aircraft type and production certification, involving heavy spending on research and development before large-scale aircraft deliveries can begin.

As of its December 2025 balance sheet, the debt-to-equity ratio was roughly 0.1x. This ratio measures total debt, including short- and long-term obligations, against shareholders' equity, with a lower number indicating less reliance on borrowed money. The so-called current ratio measures a company's ability to pay short-term obligations with assets that can be converted to cash within one year. As of its December 2025 balance sheet, the current ratio stands at approximately 19.9x.

Archer reported a debt-to-equity ratio of about 0.1x, which compares its total debt to the value owned by shareholders. Free cash flow was roughly negative $511.7 million, calculated as cash from operations minus capital expenditures.

AST SpaceMobile is building the first space-based cellular broadband network designed to connect directly to standard smartphones for commercial and government use. Its strategy, detailed in its latest annual report, relies on partnering with mobile network operators like AT&T Inc (NYSE:T) and Verizon Communications (NYSE:VZ) to fill coverage gaps for nearly 3 billion subscribers. With definitive agreements with these major carriers and various U.S. government agencies, customer concentration like this adds a layer of risk to the business. That said, it also counts Vodafone Group (NASDAQ:VOD) and Saudi Telecom Co as strategic international partners who help it navigate local regulatory markets.
