# Who are the key customers and suppliers of Hitachi?

# Hitachi (6501 JP) — Key Customers and Suppliers

Hitachi is a Japanese diversified conglomerate organized around four reporting segments: **Digital Systems & Services (DSS)**, **Energy** (Hitachi Energy), **Mobility** (Hitachi Rail), and **Connective Industries (CI)** [2]. Because the group sells across IT, power-grid, rail, and industrial verticals, its customer base is highly fragmented and skews toward institutional buyers (utilities, transit authorities, manufacturers, financial institutions) rather than retail. Likewise, "suppliers" are largely internalized within the One Hitachi framework — most of Hitachi's strategically critical inputs (digital engineering, sensor IP, power-electronics, IT/OT integration) come from subsidiaries it has acquired and consolidated. Below is the mapped picture from internal CLSA research and Hitachi's own IR disclosures.

## 1. Key Customers (By Segment)

### DSS / Digital — IT services and software (via GlobalLogic, Hitachi Vantara, Hitachi Digital)
Customer disclosures from Hitachi IR/investor-day events name specific anchor accounts that Hitachi uses publicly as flagship case studies:

| Customer | Vertical | Use case |
|---|---|---|
| **Stellantis** | Auto OEM | Dedicated facility with GlobalLogic, 100+ digital engineers building a software-defined vehicle (SDV) platform [10] |
| **McDonald's** | QSR / Consumer | Digital self-ordering system design (GlobalLogic) [8] |
| **Raiffeisen Bank International** | European financial | Cloud modernization via Hitachi Application Reliability Center (HARC); >100 apps migrated with 300+ planned [10] |
| **Lumada Innovation Hub Tokyo (LIHT)** | Cross-industry co-creation | 15,000 customer visits and 75 co-creation cases in a single FY [8] |

The DSS sector is positioned to combine "IT, OT and products" sold through a "co-creation" model that starts from the customer's challenge, and the GlobalLogic "Lab Model" — embedded labs at customer sites — has been deployed with **more than 100 customers over the past 15 years** [10].

### Energy — Hitachi Energy (former ABB Power Grids)
Hitachi Energy traces its lineage to the 19th-century founding of ASEA and BBC; ABB was formed ~100 years later from their merger, and **ABB Power Grids became part of Hitachi** in the deal that closed in 2020 [6]. Today, Hitachi Energy is "a leader in connecting renewable power generation to the grid" and a leader in transformers, substations, switchgear, and the systems/services of the total power system [7]. Its customers are global **utilities, grid operators, and renewable-energy developers** — public examples include the **Dogger Bank** (UK offshore wind) HVDC voltage-source-converter project. Importantly, Hitachi flags that its current service ratio is **less than 1% of contracts** today and targets ~25% in the long term — meaning utility customers are mostly buying hardware (HVDC, transformers, switchgear) plus a growing services tail [4].

### Mobility — Hitachi Rail
Hitachi Rail's customers are **transit authorities, national rail operators, and city governments**. The IR materials highlight the **Genoa, Italy smart-mobility deployment**, where 7,000+ sensors across subways, buses, and stations are integrated into a digital ticketing / fleet-optimization system [11]. Hitachi has also been progressive in **selling its HMAX digital service into competitors' rail vehicles** (i.e., third-party OEMs' rolling stock that Hitachi did not manufacture) — broadening TAM beyond its own installed base [3].

### Connective Industries (CI) — building systems, white goods, water, industrial
Customers here are mainly **building owners and developers** (elevator/escalator buyers, predominantly in China), **municipal water utilities**, and **industrial / manufacturing end-users** for high-tech tools (Hitachi High-Tech serves the semiconductor capex chain). CLSA flags China construction FAI exposure and elevator/escalator competition as principal CI-segment risks.

## 2. Key "Suppliers" — Internalized via M&A under One Hitachi

Hitachi's strategic dependence on outside vendors is muted because most mission-critical capabilities have been acquired and absorbed under the **"One Hitachi"** umbrella. Internal CLSA research lists the integration of **Lumada IoT solutions** across each segment as Hitachi's core value driver [5]. The functional "suppliers" within the group are:

| Internal supplier (subsidiary) | What it supplies to the group |
|---|---|
| **GlobalLogic** (acquired 2021, ~$9.6B) | Digital product engineering, software development talent, "chip-to-cloud" capability — embedded into Energy, Rail, and CI segments. Approximately **500 GlobalLogic engineers were already working with Hitachi Energy and Hitachi Rail**, with a target of over 1,000 [10] |
| **Hitachi Energy** (former ABB Power Grids, acquired 2020) | HVDC valves, transformers, switchgear, grid-automation IP; brings ASEA/BBC/ABB engineering heritage [6] |
| **Hitachi Vantara** | Data storage, infrastructure, hybrid-cloud platforms — integrated under Hitachi Digital |
| **Hitachi Digital** | Lumada/HMAX platform orchestration — combines hardware know-how with software [1] |
| **Hitachi Rail** | Sensor technology acquired through prior M&A (used for HMAX predictive maintenance) — Hitachi explicitly cited its "unique sensor technologies acquired via M&A" as the basis for HMAX successes [1] |
| **Hitachi High-Tech** | Semiconductor process equipment / analytical instruments |
| **Hitachi GLS** | White goods (consumer appliances; flagged as a potential non-core candidate) |

CLSA's investment thesis itself attributes Hitachi's value drivers to **green-energy demand, Hitachi Energy power-grid services, GlobalLogic DX consulting, and Lumada integration with Hitachi hardware** — i.e., the "suppliers" most material to the equity story are all wholly-owned subsidiaries, not third parties [5].

## 3. Caveats

- The CLSA O-PF note dated 11 June 2025 [2] is the most recent piece of internal CLSA coverage of Hitachi in the org's RMS archive; it is a strategy/IR-day update and **does not contain a formal "top-10 customer" disclosure** (Hitachi does not publish customer-concentration tables). The specific customer names in the table above are sourced from Hitachi's own IR/investor-day commentary on the Manticore corpus.
- Hitachi's structural sales mix is **B2B/B2G, with no single dominant end-customer** — the closest thing to concentration risk is sectoral exposure (global utility capex for Energy, Japan/EU rail operators for Mobility, and Chinese construction for CI).
- For a formal supplier list (component vendors such as semiconductor foundries, power-electronics IGBT suppliers, IT system OEMs), refer to Hitachi's **annual securities report** (有価証券報告書) — none of these are surfaced in the internal CLSA coverage.
