Considering sustainability standards in investment activities, the Group supports the sustainable development of society at large while also enhancing the performance of its investments over the medium to long term. Under this belief, the Group is undertaking the following initiatives.

Actively committed to integrating ESG into the investment process, SoftBank Group Corp. has established the Portfolio Company Governance and Investment Guidelines Policy. The Policy sets out criteria for assessing portfolio companies’ governance systems during the investment process. It also states that environmental and social risks and opportunities are to be assessed in this process. The Policy applies to SoftBank Group Corp. and its subsidiaries,^* each of which develops and carries out its own specific investment plans.

Softbank Vision Funds integrate ESG into their investments in the following ways.

In consideration of its importance to the international community and the Group’s investment business, SoftBank Vision Funds have identified four key themes to be assessed prior to investment: responsible AI, climate change, human rights (forced labor; discrimination and harassment) and governance. SoftBank Vision Funds assess how these themes are addressed by potential portfolio companies through due diligence, assess the associated risks, and incorporate the findings into their investment decisions. SoftBank Vision Funds review the important themes and assessment methods as necessary in response to changes in their external environment and business strategies, and reflect the latest sustainability issues and assessment perspectives.

After investing, SoftBank Vision Funds continually monitor the portfolio companies to prevent risks from materializing. With regard to key themes, SoftBank Vision Funds conduct engagements (dialogue) that deepen their understanding of portfolio companies’ initiatives and encourage further improvement, thereby contributing to the sustainable development of society as a whole and enhancing medium- to long-term investment performance.

SoftBank Group Corp. monitors and oversees the integration of ESG into the SoftBank Vision Funds’ investment process through reports to the Board of Directors in addition to the Sustainability Committee on the investment process and assessment results.
