AI Data Center And Defense Tailwinds Will Eventually Expose Lithium Execution Risks

About EnerSys

EnerSys supplies stored energy solutions for applications such as data centers, communications networks, motive power, and aerospace and defense.

What are the underlying business or industry changes driving this perspective?

• The shift toward AI heavy data centers and higher energy density requirements could expose EnerSys to intense competition in lithium systems. If OEM validation, hyperscaler qualifications and supply chain set up for its new lithium data center product slip beyond the current fiscal 2028 revenue expectations, revenue growth and scale benefits in Energy Systems may disappoint.
• Warehouse and motive power customers are gradually adopting battery energy storage solutions to deal with grid constraints and labor costs. Yet if EnerSys struggles to convert early commissioning wins in warehouse BESS into broad commercial rollouts, maintenance free penetration and related charger sales may fall short of offsetting forklift market volatility, tempering Motive Power revenue and pressuring segment margins.
• Electrification of defense platforms, drones and soldier power is increasing the need for secure domestic lithium supply. If the Greenville cell factory program, DOE grant process or customer commitments in aerospace and defense do not materialize at the scale management is organizing for, capital employed in this facility could weigh on returns and limit future earnings contribution from the Specialty segment.
• Growing demand for network resilience, DOCSIS 4.0 upgrades and broadband power supplies is currently helping Energy Systems. If carriers moderate capex or push out network refresh cycles after the current build phase, the project based nature of this business could lead to order lumpiness that restricts pricing power and keeps adjusted operating margins closer to current levels rather than expanding.
• Rising global defense budgets and munitions spending are supporting EnerSys orders and backlog in aerospace and defense. Yet if governments reset priorities or slow procurement after current conflicts subside, the company could face a step down in high mix, higher margin defense revenue that would make it harder to maintain recent adjusted EPS levels and record margin performance.

Assumptions

How have these above catalysts been quantified?

• This narrative explores a more pessimistic perspective on EnerSys compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts.
• The bearish analysts are assuming EnerSys's revenue will grow by 3.1% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from 7.8% today to 12.4% in 3 years time.
• The bearish analysts expect earnings to reach $511.9 million (and earnings per share of $12.87) by about June 2029, up from $293.6 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the more bearish analyst cohort, the company would need to trade at a PE ratio of 15.4x on those 2029 earnings, down from 28.2x today. This future PE is lower than the current PE for the US Electrical industry at 36.3x.
• The bearish analysts expect the number of shares outstanding to decline by 2.53% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 9.85%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• EnerSys is already reporting record full year net sales of US$3.8b, record adjusted operating profit of US$382 million before 45X benefits and record adjusted diluted EPS of US$6.41 before 45X benefits. Continued execution on this higher earnings base could support earnings and cash flow rather than a weaker share price, particularly if the adjusted operating margin around 10.2% is sustained or improves.
• Long term demand trends in data centers, broadband, communications and AI related infrastructure are described as healthy, with high single digit data center revenue growth in fiscal 2026 and 36% higher data center orders year on year. This could support revenue and mix in Energy Systems if these projects convert from backlog into shipments and help maintain or lift segment operating margins around 10%.
• Defense, aerospace and munitions orders are strong, with A&D revenue up mid 20% year on year and sequentially, a book to bill of 1.22 and a growing backlog in munitions and space. Sustained or rising global defense budgets and the Greenville lithium cell project focused on secure domestic supply could continue to support Specialty segment revenue, margins in the mid to high teens target range and overall earnings.
• The Motive Power and transportation businesses are already seeing order growth, including industry forklift orders up 40% in a prior quarter and Motive Power orders up 19% sequentially with a company wide Q4 book to bill of 1.1. A recovery from recent market softness and release of pent up replacement demand could support volume, revenue and margin recovery in Motive Power rather than prolonged weakness.
• EnerSys is showing strong free cash flow of US$468 million for the year with conversion of 159% and 236% excluding 45X, a leverage ratio of 1.1x EBITDA and sizeable share repurchases and dividends. Continued cash generation, tariff refunds and disciplined capital allocation could support EPS through buybacks and reduce financial risk, which may in turn support the share price rather than pressure it.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The assumed bearish price target for EnerSys is $176.43, which represents up to two standard deviations below the consensus price target of $241.29. This valuation is based on what can be assumed as the expectations of EnerSys's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $265.0, and the most bearish reporting a price target of just $176.43.
• In order for you to agree with the more bearish analyst cohort, you'd need to believe that by 2029, revenues will be $4.1 billion, earnings will come to $511.9 million, and it would be trading on a PE ratio of 15.4x, assuming you use a discount rate of 9.8%.
• Given the current share price of $227.08, the analyst price target of $176.43 is 28.7% lower. Despite analysts expecting the underlying business to improve, they seem to believe the market's expectations are too high.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
