Full Analysis
Cummins Inc. reported third-quarter 2026 revenues of $9.44 billion, representing a 13.5% increase year-over-year but missing the Zacks Consensus Estimate due to supplier constraints and weaker pickup truck demand. Adjusted EPS of $7.71 also fell short of analyst expectations at $8.38. Consequently, management lowered its full-year 2026 revenue guidance to roughly 10% growth, citing the low end of its previously guided range. Despite the quarterly miss, Cummins' Power Systems segment remains a significant growth driver, with third-quarter sales rising 15% to $2.29 billion and EBITDA margins expanding to 25.4%. The company is capitalizing on surging demand for backup and prime power from hyperscalers building AI data centers, with orders extending into the second half of 2028. Geographically, North American power generation revenues grew 22%, while China's power equipment sales jumped 42%. To address supply constraints and meet growing demand, Cummins is investing heavily in capacity expansion, including a new $100 million cooling-systems plant in Wisconsin and additional generator capacity coming online in 2027. The company also secured its largest battery energy storage project to manage AI workload fluctuations and is developing natural gas engines for commercialization around 2029. However, weakness in the traditional truck market continues to offset some of this strength. Cummins shares have declined 12% year-to-date, underperforming peers like Caterpillar and Eaton, while trading at a forward sales multiple of 1.52x compared to higher multiples for competitors. Analysts maintain a Zacks Rank #3 (Hold) rating, noting that while the long-term AI data center opportunity is compelling, investors should wait for more consistent revenue growth and stronger execution before considering it an immediate buy.
