Supply Chain Management
SoftBank will continue to develop together with our suppliers.
SoftBank has always chosen suppliers that share our vision toward social contribution, working together to create innovative services offering new lifestyle propositions.
“We foster relationships of trust based on mutual understanding, and improve by learning from each other for the benefit of our customers.”
“We maintain fair relationships with suppliers and provide an environment where customers can choose quality products and services with confidence.”
“We share a passion for contribution to society through our products and services, and pursue innovation together with our suppliers.”
SoftBank evolves together with its suppliers.
Basic policy
Procurement Policy
In order to maintain fair and positive relationships with suppliers, the Procurement Policy of SoftBank Corp. stipulates the following eight items: “provision of fair opportunities for competition,” “selection of suppliers based on rational and clear criteria,” “compliance with laws,” “management of confidential information provided by suppliers,” “mutual confidence-building with suppliers,” “environmental conservation,” “prohibition of mixing private relations,” and “commitment to sustainability”. All procurement activities conducted by the Procurement Department are carried out in accordance with these basic policies.
The contents of each item are disclosed on this website, and efforts are made to inform and promote understanding of these items among relevant parties both within and outside the company.
Supplier Ethics and Rules of Conduct
In order to deal with sustainability-related issues together with suppliers, provide reliable and safe products and services to customers, and conduct business activities which are trusted by society, we have established the “Supplier Ethics and Rules of Conduct” and request that all suppliers comply with these rules.
The “Supplier Ethics and Rules of Conduct” includes 14 items which consist of “Concern for the environment,” “Information security,” “Fair competition,” “Ensure quality and safety,” “Consideration for Human Rights,” “Occupational safety and health,” “Prohibition of child labor,” “Prohibition of forced labor,” “Prohibition of discrimination and inhumane treatment,” “Working hours,” “Fair payment,” “Freedom of association,” “Responsible mineral procurement,” and “Coexistence with local communities.”
Green Procurement Guidelines
Moreover, to contribute to the sustainable development of society by actively working to maintain and conserve the global environment through our business activities, we have established the “Green Procurement Guidelines” which indicate our fundamental approach to green procurement for all of our suppliers.
These guidelines are in accordance with the contents of the “Ecology Guideline for the ICT Industry,” which was formulated by the ICT Ecology Guideline Council* in response to the proposal by the workshop concerning the ecological response in the information and telecommunications field hosted by the Ministry of Internal Affairs and Communications.
Our goal in establishing these guidelines is to promote the procurement of products which contribute to the reduction of CO2 emissions.
We highly value the voluntary and proactive proposals from our suppliers and will engage in business activities with an environmental emphasis by engaging in environmental conservation activities together with the suppliers.

System
The Procurement Department oversees a series of purchasing operations, such as selection of suppliers, ordering and contracting, management of transactions including quality, delivery, safety, etc. after transactions start, and management of suppliers, as part of procurement activities such as purchase of materials, equipment, and services required for business activities, and establishes policies and processes related to purchasing operations and executes purchasing operations in a centralized purchasing system. The department is in charge of centralized purchasing, and the General Manager of the Finance & Controlling Cost Management Division is responsible for this division. In order to properly manage the supply chain in accordance with the above policies and guidelines, the Procurement Department regularly discusses with each department to ensure prompt coordination among the departments. The ESG Committee (Chairman: Junichi Miyagawa), established as an advisory body to the Board of Directors, oversees the activities of the Supplier ESG Program in order to enhance supply chain sustainability. The FP&A and Procurement Division, Finance Unit reports to the ESG Committee on supply chain sustainability procurement activities as necessary, and the committee deliberates on issues and responses.
Supply chain overview and supplier selection criteria
Supply chain overview
SoftBank's supply chain is spread across various countries and regions around the world; in fiscal year 2024, the supplier spending ratios by region are 53% in Japan, 38% in the Americas, 5% in Asia, and 4% in Europe. In addition, by category, supplier spending ratios are 37% for devices, 37% for service and construction, 18% for equipment (and maintenance), and 8% for others.

Supplier selection and evaluation cycle
When selecting suppliers, we evaluate suppliers in terms of quality, price, delivery, supply stability, reliability, etc., and conduct business with suppliers that meet minimum standards, while conducting ongoing supplier risk assessments, including sustainability perspective. We reduce risks within the supply chain by establishing a PDCA cycle, which includes the establishment of the Supplier Ethics and Rules of Conduct, conducting Sustainability Procurement Survey, evaluating suppliers and identifying issues, and conducting supplier inspections and audits. In our purchasing activities, we regularly review our supplier selection criteria, the content of supplier surveys, and audit criteria and items to ensure that they are in line with our Supplier Ethics and Rules of Conduct. In addition, when starting a new transaction with a supplier, we evaluate and select the supplier in accordance with our purchasing rules, and conclude a basic transaction agreement that includes the supplier's compliance with our Supplier Ethics and Rules of Conduct. ESG aspects of environmental, social and governance are included and applied a certain weight to the supplier evaluation for telecommunications and IT equipment procured for use in the services we provide, as well as for some facility equipment installed as part of our telecommunications infrastructure.

Significant suppliers
Relationships with various suppliers are important when it comes to conducting business activities.
We have more than 2,000 suppliers around the world, and in our supply chain management, we identify significant suppliers from the perspective of transaction volume, substitutability and ESG aspects of environmental, social and governance and conduct appropriate supply chain management as a significant supplier which cover the top 80% or more of the previous year's purchases among a wide range of suppliers.
Criteria for selecting significant suppliers
Suppliers of key products | Suppliers that handle key products and components such as radios, base stations and networks that support the core domestic telecommunications business (mobile and fixed-line businesses). |
---|---|
Non-substitutable Suppliers | Suppliers that can not be substituted (in view of the fact that there are essentially no substitute products on the market, or that a long-term disruption of the supply chain would critically damage the core business). |
Suppliers with High Transaction Volume | Suppliers that have transactions above a certain amount. |
Suppliers with low sustainability risks | Excellent ESG aspects of environmental, social, and governance, with no risks identified by region, sector, or procurement category. |
Building a sustainable supply chain
Sustainability procurement survey
We conduct an annual sustainability procurement survey of our significant suppliers in order to identify potential “sustainability risks” in our supply chain and take appropriate measures. We believe that in order for suppliers to achieve better ESG performance, it is important to understand examples of other companies, therefore we evaluate survey results and provide feedback, including comparisons with other companies.
To promote sustainability initiatives by suppliers, we share the results of sustainability procurement survey and introduced EcoVadis in FY2024 to create an environment where suppliers can reference outstanding initiatives, including comparisons with other companies. Suppliers identified as having ESG issues or potential risks are asked to prepare corrective action plans. If a supplier does not meet the minimum ESG requirements through audits, etc., we will recommend corrective actions and encourage continuous improvement If we do not confirm that the supplier has presented remedial measures to correct serious nonconformities within 90 days, we will consider discontinuing the use of that supplier after making a comprehensive judgment, taking the business into consideration.

Positioning with materiality
Our materiality is linked to (4) Contributing to the global environment through the power of technology and (6) Developing a resilient management base, and we are working throughout our supply chain to contribute to solving global CSR issues together with our wide range of suppliers.
Efforts toward sophistication
Collaborate with other companies by participating in related initiatives
We are a member of the Supply Chain Subcommittee of the Global Compact Network Japan (GCNJ), and are working with companies in various industries to share practical issues related to social and environmental problems, including human rights abuses in supply chains, and to produce outputs to support their resolution, with the aim of promoting sustainable supply chain management in a wide range of industries.
We have announced collaboration among telecommunications carriers on sustainable procurement with NTT, Inc. and KDDI Corporation to hold regular meetings and create a common SAQ for the telecommunications industry to standardize questionnaires on sustainability and reduce the burden on our suppliers.
In FY2024, we introduced EcoVadis, a third-party evaluation platform to further strengthen engagement with suppliers, and SAQ* common to the three companies (NTT, KDDI, and SoftBank).
We published a handbook that introduces our sustainability initiatives, our approach to sustainability, our own CO2 emissions measurement, and other initiatives that we would like our suppliers to implement, and we will support our suppliers' activities to improve sustainability in their supply chains. In addition, three companies (NTT, KDDI, and SoftBank) have begun jointly conducting third-party audits of suppliers and proposing improvements based on the audit results.

Supplier Engagement
We believe that part of our responsibility for our products and services is not only to provide our customers with an environment where they can select better products and services with confidence, but also to ensure that human rights are respected and a safe working environment is maintained throughout the supply chain, and that an environmentally friendly business environment is also maintained. We regard our suppliers as important partners. We conduct a variety of supplier training and engagement programs throughout the year to strengthen the capabilities of our suppliers, and to ensure the quality of the products and services they provide to us and to improve their environmental, social, and governance performance.

Reduction of greenhouse gas emissions
through the supply chain (Scope 3)
SoftBank Corp. will work to achieve Net-Zero emissions by 2050, which means zero emissions of all greenhouse gases related to our business activities, including not only greenhouse gases emitted from electricity used in our business activities (Scope 1 and 2) but also from our entire supply chain (Scope 3).
Since the overwhelming majority of our products are Scope 3, we need to decarbonize our entire supply chain, and it is essential that we promote this with our suppliers. We have established “Guidelines for Reducing Greenhouse Gas Emissions in the Supply Chain” and will promote purchasing activities to achieve net-zero emissions.
Internal Carbon Pricing
In order to strongly promote our response to climate change, we expanded the Internal Carbon Pricing (ICP) system in FY2024. The scope of the program has been expanded to Scope 1 and 2, and an implicit price (18,000 yen/t-CO2) has been set for some capital investments that can achieve CO2 emissions reductions to promote the introduction of equipment that will further promote decarbonization.
Nature Positive
Our company supports the achievement of “Nature Positive” pursued by the international community and promotes efforts to reduce the impact on biodiversity and address any deforestation associated with business activities, including our suppliers, in order to contribute to its realization.
Establishment of guidelines for procurement activities
in consideration of human rights
For goods, novelties, and promotional items in our sustainability procurement activities, we have established “Guidelines for Human Rights Conscious Procurement Activities for Goods, Novelties, and Promotional Items” and confirm compliance with the guidelines before placing orders.
Electronic trading system
In order to promote purchasing activities, SoftBank Corp. is promoting operations using an electronic transaction system (Web-EDI). EDI* is an electronic exchange mechanism used exclusively between businesses (B to B). In fiscal year 2023, the EDI order placement rate was 90%, and we are working to increase the rate to 90% or higher in fiscal year 2024 and beyond.

Improving the skills of purchasing managers
In purchasing operations, when negotiating with various suppliers for the purpose of procuring goods, it is required to achieve continuous and stable procurement through fair, equitable and transparent transactions. In order to achieve this goal, we conduct basic training for purchasing staff (e.g., on the Act against Delay in Payment of Subcontract Proceeds to subcontractors) every year, as well as basic training for new purchasing staff, and promote the acquisition of the Certified Procurement Professional (CPP) certification, an external qualification, to improve procurement and purchasing skills. We also provide education on basic knowledge of supplier ESG program for purchasing staff once a year, and we have incorporated goal achievements related to sustainable procurement into personnel evaluations for purchasing staff.
