StockStory’s Take

EnerSys faced a challenging fourth quarter, as the company’s revenue growth lagged behind Wall Street expectations. Management cited ongoing weakness in its Motive Power and Transportation segments, which were affected by delayed customer spending and continued softness in capital investments. CEO Shawn O’Connell described the environment as "dynamic," emphasizing that while end markets such as data centers and defense remained resilient, the near-term softness in core industrial sectors weighed on overall performance.

Looking ahead, EnerSys’s guidance rests on continued strength in data centers and defense, as well as the anticipated benefits from recent operational changes and cost initiatives. Management pointed to opportunities in lithium battery solutions, ongoing restructuring savings, and a resilient data center pipeline as key drivers. O’Connell noted, "We are highly confident in our focused growth strategy, supported by durable secular demand trends, including the growing need for energy security and high-performance energy storage solutions."

Key Insights from Management’s Remarks

Management attributed the mixed quarterly results to persistent end-market challenges, but highlighted progress in high-growth verticals and cost control initiatives.

• Data center momentum: EnerSys reported 28% year-over-year sales growth in its data center business, driven by robust demand from hyperscale customers and increasing needs for energy resilience in artificial intelligence (AI) workloads. Management believes this segment is still in the early stages of a multi-year growth cycle.
• Operational cost savings: The company executed restructuring initiatives, including the closure of its Monterrey battery plant and realignment efforts, which are expected to yield ongoing cost benefits. CFO Andrea Funk stated these actions produced approximately $15 million in quarterly savings and will continue impacting results.
• Motive Power and Transportation softness: Both segments continued to experience sluggish demand due to delayed ordering cycles and customer capital expenditure constraints. However, leadership maintains that pent-up demand exists and expects eventual recovery as aging fleets require replacement.
• Specialty and defense strength: The Specialty segment, particularly aerospace and defense (A&D), saw strong performance with a 27% increase in A&D backlog. Management cited global defense budget increases and robust demand for next-generation power technologies as key contributors.
• Tariff management: EnerSys managed tariff headwinds through proactive supply chain adjustments and pricing strategies, maintaining direct tariff exposure at roughly $70 million annually. The company’s task force continues to seek supply chain optionality to mitigate future risk.

Drivers of Future Performance

EnerSys’s outlook is shaped by expected strength in data center and defense markets, alongside ongoing operational discipline and product innovation.

• Data center lithium rollout: Management anticipates the upcoming launch of lithium battery products for data centers will open new market opportunities, as EnerSys currently has no presence in this fast-growing segment despite holding over 50% share in lead-acid solutions. Initial customer trials are planned, with a gradual ramp expected over the next year.
• Operational efficiencies and restructuring: Continued cost discipline, including benefits from plant closures and workforce reductions, are expected to support margin improvement. The company projects these initiatives will help operating earnings grow faster than revenue, even as Motive Power volumes remain soft.
• Uncertainty in industrial recovery: While pent-up demand in Motive Power and Transportation is recognized, management remains cautious regarding the timing of recovery. Delayed capital investments from key customers and lingering tariff impacts may continue to pressure volumes in the near term.

Catalysts in Upcoming Quarters

In upcoming quarters, the StockStory team will be monitoring (1) the adoption and scaling of EnerSys’s lithium battery solutions in data centers, (2) the pace of recovery in Motive Power and Transportation demand as delayed customer investments potentially resume, and (3) sustained backlog growth in defense and specialty markets. Progress on operational efficiencies and the finalization of the lithium cell factory plan will also be important to watch.

EnerSys currently trades at $159.69, down from $185.03 just before the earnings. Is there an opportunity in the stock?The answer lies in our full research report (it’s free).
