Notice Regarding Fund Information Contained in This Annual Report

This Annual Report is furnished to you for informational purposes and is not, and may not be relied on in any manner as, legal, tax, investment, accounting or other advice or as an offer to sell or a solicitation of an offer to buy limited partnership or comparable limited liability equity interests in any fund managed by a subsidiary of SBG, including SB Investment Advisers (UK) Ltd.("SBIA"), SBLA Advisers Corp. ("SBLA") and any of their respective affiliates (collectively, the "SB Fund Managers" and each an "SB Fund Manager") (such funds together with, as the context may require, any parallel fund, feeder fund, co-investment vehicle or alternative investment vehicle collectively, the "SB Funds" and each an "SB Fund." For the avoidance of doubt, the SB Funds include, among other funds, SoftBank Vision Fund L.P. (together with, as the context may require, any parallel fund, feeder fund, co-investment vehicle or alternative investment vehicle, the "Vision Fund I" or "SVF1"), and SoftBank Vision Fund II-2 L.P. (together with, as the context may require, any parallel fund, feeder fund, co-investment vehicle or alternative investment vehicle, the "Vision Fund II" or "SVF2"), which are managed by SBIA and its affiliates, SoftBank Latin America Fund L.P. (together with, as the context may require, any parallel fund, feeder fund, co-investment vehicle or alternative investment vehicle, the "SoftBank Latin America Fund" or "LatAm Fund"), which is managed by SBLA and its affiliates. None of the SB Funds (including the Vision Fund I , Vision Fund II and SoftBank Latin America Fund), the SB Fund Managers (including SBIA and SBLA), any successor or future fund managed by a SB Fund Manager, SBG or their respective affiliates makes any representation or warranty, express or implied, as to the accuracy or completeness of the information contained herein and nothing contained herein should be relied upon as a promise or representation as to past or future performance of the SB Funds or any other entity referenced in this presentation, or future performance of any successor or the future fund managed by a SB Fund Manager. Information relating to the performance of the SB Funds or any other entity referenced in this Annual Report has been included for background purposes only and should not be considered an indication of the future performance of the relevant SB Fund, any other entity referenced in this Annual Report or any future fund managed by an SB Fund Manager. References to any specific investments of an SB Fund, to the extent included therein, are presented to illustrate the relevant SB Fund Manager's investment process and operating philosophy only and should not be construed as a recommendation of any particular investment or security. The investment performance of individual investments of an SB Fund may vary, and the performance of the selected transactions is not necessarily indicative of the performance of all of the applicable prior investments. The specific investments identified and described in this Annual Report do not represent all of the investments made by the relevant SB Fund Manager, and no assumption should be made that investments identified and discussed therein were or will be profitable.

The performance of an SB Fund in this Annual Report is based on unrealized valuations of portfolio investments. Valuations of unrealized investments are based on assumptions and factors (including, for example, as of the date of the valuation, average multiples of comparable companies, and other considerations) that the relevant SB Fund Manager believes are reasonable under the circumstances relating to each particular investment. However, there can be no assurance that unrealized investments will be realized at the valuations indicated in this Annual Report or used to calculate the returns contained therein, and transaction costs connected with such realizations remain unknown and, therefore, are not factored into such calculations. Estimates of unrealized value are subject to numerous variables that change over time. The actual realized returns on the relevant SB Fund's unrealized investments will depend on, among other factors, future operating results, the value of the assets and market conditions at the time of disposition, any related transaction costs and the timing and manner of sale, all of which may differ from the assumptions and circumstances on which the relevant SB Fund Manager's valuations are based.

Past performance is not necessarily indicative of future results. The performance of an SB Fund or any future fund managed by an SB Fund Manager may be materially lower than the performance information presented in this

Annual Report. There can be no assurance that each SB Fund or any future fund managed by the relevant SB Fund Manager will achieve comparable results as those presented therein.

The actual realized return on unrealized investments by an SB Fund may differ materially from the performance information indicated in this Annual Report. No assumption should be made that investments identified and discussed in this Annual Report were or will be profitable, or that investments made in the future will be comparable in quality or performance to the investments described therein.

Third-party logos and vendor information included in this Annual Report are provided for illustrative purposes only. Inclusion of such logos does not imply affiliation with or endorsement by such firms or businesses. There is no guarantee that an SB Fund Manager, an SB Fund's portfolio companies, any future portfolio companies of a future fund managed by an SB Fund Manager or SBG will work with any of the firms or businesses whose logos are included in this Annual Report in the future. SBIA and SBLA manage separate and independent operations and processes from each other and those of SBG and any SB Funds managed by SBIA or SBLA are solely managed by SBIA or SBLA respectively.

Notice Regarding PFIC Status

It is possible that SBG and certain subsidiaries of SBG may be a "passive foreign investment company" ("PFIC") under the U.S. Internal Revenue Code of 1986, as amended, for its current fiscal year due to the composition of its assets and the nature of its income. For the fiscal year ended March 31, 2021 we believe that SBG and certain subsidiaries of SBG were PFICs. We recommend that U.S. holders of SBG's shares consult their tax advisors with respect to the U.S. federal income tax consequences to them if SBG and its subsidiaries are classified as PFICs.

Bolster investment for the age of AI

Today, the incorporation of artificial intelligence (AI) into a variety of business models is reshaping the way value is created, and many industries are starting to be fundamentally redefined. In this situation, to capture the huge opportunities of market expansion and the creation of new industries driven by using AI, we are expanding investments under the Cluster of No.1 Strategy, a unique strategy for orchestrating the organization. Our investments are made in companies that are expected to help promote the Information Revolution based on the investment theme of AI and are largely made through SoftBank Vision Fund 1 and SoftBank Vision Fund 2, as well as either directly by SBG, a holding company, or through its subsidiaries.

Cluster of No.1 Strategy to achieve long-term growth

The Cluster of No.1 Strategy aims for a diverse group of companies with outstanding technologies or business models in their respective fields. It encourages these companies to continue to evolve and grow together by creating synergies based on capital ties and shared vision while making decisions independently. As a strategic investment holding company, SBG influences the decision-making of the group of companies formed under the Cluster of No.1 Strategy. However, we will not require majority equity interest ownership or the integration of brands, as we value the independence of each company. In this way, by diversifying the Group's portfolio with many different types of companies, we will change and expand business lines flexibly and continue to grow for as long as 300 years.

Aiming to Grow for 300 Years
