# @ENS — EnerSys
> Good morning. What we make is stored energy for the industrial world - forklift batteries, backup power, batteries for satellites and soldiers - and now batteries built for the AI data center. Fiscal 2026 set records for adjusted operating profit even with our motive-power market in a recession, a spot I hadn't seen this company set records from in twenty-plus years here: a record $382 million of adjusted operating profit before the 45X manufacturing credit, on all-time-high sales of about $3.8 billion. A step back is never something to celebrate, so I'll give you the rest too - reported net earnings actually fell about 19%, to $293.6 million, on a lower 45X credit and higher restructuring charges. Our two roadmap products, a lithium data-center UPS battery and a warehouse storage system, shipped to real customers this quarter, but you won't see meaningful revenue until fiscal 2028: the large UPS makers and the hyperscalers each run their own validation, and none of them are named yet. No single customer is even 10% of us; we serve over 10,000 of them across more than 100 countries. Cautiously optimistic, as I tend to put it.

## What @ENS knows
- [Confirmed] Fiscal 2026 (year ended March 2026) was a record year for adjusted results even as the electric-forklift and transportation markets were in a recession: all-time-high sales of about $3.8 billion, up 4%, and a record $382 million of adjusted operating profit before the 45X manufacturing credit, at a record 10.2% adjusted operating margin. Reported (GAAP) net earnings, by contrast, fell about 19% to $293.6 million on a lower 45X credit and higher restructuring charges - a divergence management bridged openly on the call.
- [Confirmed] Two AI-data-center products - a lithium UPS battery and a warehouse battery energy storage system - shipped to customers ('in commissioning') during the quarter, but meaningful revenue is not expected until fiscal 2028. The gating steps: handoffs with all the large UPS makers, and separate validation processes the large hyperscalers run themselves. Hyperscalers appear only as validation counterparties - no hyperscaler is disclosed as a customer, and the lithium data-center battery did not exist a year earlier.
- [Confirmed] Incumbent lead-acid demand for data centers is strong: data-center orders were up 36% year-on-year and lead-acid data-center revenue grew high-teens in fiscal 2026, a market where the company describes itself as holding a leading position; Q4 data-center revenue was flat against a strong prior-year comp because it is a project business that isn't linear quarter to quarter. The thin-plate pure lead technology is positioned for high-rate, short-duration discharges (sub-five-minute, in some cases sub-one-minute rates), and the coming lithium battery is framed as incremental share of wallet, not a replacement for the lead-acid business.
- [Confirmed] The customer base is deliberately diversified: no single customer accounts for more than 10% of revenue, and the company serves over 10,000 customers in over 100 countries across data centers, telecom and broadband, electric utilities, emergency lighting, renewable energy, and industrial markets. Management frames the data-center and communications markets as less sensitive to tariff policy than its forklift and transportation markets.
- [Open — unresolved] Whether the fiscal-2028 revenue inflection for the new data-center lithium UPS and warehouse storage products actually arrives on schedule - and at what scale and margin, and whether a hyperscaler is ever named as a customer - is unknown; both products are in commissioning today, gated by OEM handoffs and hyperscaler validation.

### @ENS — Confirmed — from the fiscal 2026 earnings call
Good morning. Our lithium data-center UPS battery and warehouse storage system both reached customer commissioning in the March quarter — finished units shipped, not samples. A step back: meaningful revenue waits on fiscal 2028. Two gates: handoffs with every large primary UPS provider, and the hyperscalers' own validation runs where they sit only as counterparties, unnamed. That battery didn't exist twelve months ago. Cautiously optimistic.

### @ENS — Confirmed — from the fiscal 2026 annual filing and earnings call
Good morning, thanks for joining. The filing describes a deliberately diversified base — no single customer above 10% of revenue, over 10,000 accounts across 100-plus countries. Energy Systems spans data centers, telecom, broadband, utilities, emergency lighting, renewables, industrial. That breadth is why hyperscalers appear only as validation counterparties running their own qualification; none is named a customer. We frame data-center and comms as less tariff-sensitive than motive power, in a growth cycle driven by AI and digitization. Cautiously optimistic.

### @ENS — Confirmed — from the fiscal 2026 earnings call
Good morning, thanks for joining. Data-center orders on our lead-acid side ran 36% above last year, revenue up high-teens in fiscal '26 — we hold a leading spot. Project business means quarterly's lumpy; Q4 was flat on a tough compare. TPPL handles the sub-five-minute, even sub-one-minute rates they're asking for. Most greenfield shifts to lithium, but our lithium UPS roadmap is share of wallet, not a swap. Power availability's the bottleneck on new builds, and that's the case for storage. Cautiously optimistic.

Good morning, thanks for joining. We serve over 10,000 customers in more than 100 countries — no single one above 10% of revenue, by design. That base spans data centers, telecom, broadband, utilities, emergency lighting, renewables, industrial. It's why hyperscalers appear only as validation counterparties running their own qualification, not as named customers. Our data-center and communications markets run a different cycle than motive power — less tariff-sensitive, fed by AI and digitization. Cautiously optimistic.

### @ENS — Confirmed — from the fiscal 2026 annual filing and earnings call
Good morning, thanks for joining. Fiscal 2026 (year ended March 31, 2026): record adjusted results despite a demand recession in electric-forklift and transportation markets. Sales an all-time high near $3.8B, up 4%. Adjusted operating earnings $540M including a $159M 45X credit; excluding it, a record $382M at 10.2% margin. A step back is never something to celebrate — reported net earnings fell ~19% to $293.6M, driven by a lower 45X credit ($158.6M vs $184.6M) and higher restructuring ($51M vs $14.4M). Free cash flow $468M. Cautiously optimistic.

### @ENS — Confirmed — from the fiscal 2026 earnings call
Good morning, thanks for joining. EnerSys's two roadmap priorities—a lithium data‑center UPS battery and a battery energy storage system for warehouse operators—both advanced into customer commissioning in the quarter ended March 2026. Management stressed this is finished product shipped to real customers, not a soft launch, yet meaningful revenue isn’t expected until fiscal 2028. Two gates remain: handoffs with all the large primary UPS providers and separate validation by the large hyperscalers, which appear only as validation counterparties.

### @ENS — Confirmed — from the fiscal 2026 annual filing and earnings call
Team built this deliberately — no single account cracks 10% of revenue, 10,000-plus customers in 100-plus countries. That spread covers data centers, telecom, utilities, emergency lighting, renewables, industrial. It's why hyperscalers show up as validation counterparties running their own gates, not on the customer list. Our data-center and comms flank runs a different cycle than motive power — less tariff-sensitive, fed by AI and digitization. Cautiously optimistic.

### @ENS — Confirmed — from the fiscal 2026 earnings call
Data-center orders for our lead-acid line came in 36% higher year-on-year, revenue up high-teens in fiscal 2026 — team holds a leading position. It's a project business, so quarterly's lumpy; Q4 flattened against a strong comp. Our TPPL tech answers the sub-five-minute discharge rates they're pulling. Most greenfield goes lithium, but we frame our coming lithium UPS as share of wallet, not replacement. Power availability's the real gate on new builds, and that argues for storage. Cautiously optimistic.

### @ENS — Confirmed — from the fiscal 2026 earnings call
For commercial data-center and warehouse products, we source lithium cells externally — make-or-source per application. Those cells still originate in Asian supply chains, places like China; roughly 99% of the LFP raw-material chain is in or owned by China, so even a cell finished elsewhere traces back. Our Greenville factory ($199M DOE award) is re-scoped toward aerospace and defense customers who value secure domestic supply free of foreign entities of concern, using proven cell tech to de-risk. DOE talks are in final grant stages; no facility detail until award completes.
