Risks & Mitigants

EnerSys operates in highly competitive and cyclical markets, facing risks that include:
• Commodity Volatility: Lead, lithium and other raw-material prices fluctuate. Hedging and cost-pass-through pricing protect margins.
• Supply Chain: Global semiconductor and electronics shortages resolved, but emerging risks (geopolitical tensions, tariffs).
• Cyclical Demand: Investment pauses in telecom/industrial end markets; offset by diversification into data center, defense and EV charging.
• Regulatory: Adapting to evolving environmental, trade, subsidy and tax legislation (e.g. EUattery regulations, U.S. IRA).
• Currency & Interest: $330M+ cash outside the U.S.; exposure hedged through multi-currency derivatives and interest‐rate swaps.

EnerSysalanced portfolio—spanning UPS, material handling, defense & aerospace—along with recurring service contracts, creates stability even amid cyclical headwinds.

Outlook & Valuation

EnerSys enters FY 2026 with several tailwinds:

• IRA production tax credits (45X) unlocking meaningful margin expansion.
• Escalating global demand for energy storage, backup power, and EV charging infrastructure.
• Continued growth in defense/aerospace budgets supporting specialty segments.
• Gigafactory joint venture aiming at U.S. cell production, securing domestic supply chain.

At a ~10x multiple of FY 2026 EBITDA – adjusted for Section 45X benefits & inorganic growth – EnerSysurrently trades at a discount to industrial peers. With a 30%-+ gross margin profile, 12%-+ operating margin and 1.3x net debt/EBITDA, the Company ppears both reasonably valued and positioned for sustainable, profitable growth.

Investment Score: 7.4/10—A core industrial play in electrification and infrastructure modernization, with visible margin upside.
