(Note 1) “Shareholding ratio” means the ratio to 92,707,684 shares of the Target Company Stock, which is the total number of issued shares as of July 31, 2020 (i.e., 95,857,420 shares) set forth in the “2nd Quarterly Report for the 111th Fiscal Year” (the “Target Company Quarterly Report”), as filed by the Target Company on September 10, 2020, less the number of the treasury shares held by the Target Company as of the same date stated in the Target Company Quarterly Report (i.e., 3,149,736 shares) (rounded off to the second decimal place). 1 To implement the Tender Offer, as stated in “(a) Tender Agreement” of “(6) Matters Concerning Material Agreements Related to the Tender Offer” below, the Tender Offeror, as of today, received a letter from Mizuho Bank, Ltd., the Target Company’s second largest shareholder (number of shares owned: 4,282,324 shares; shareholding ratio: 4.62%; “Mizuho Bank” or the “Tendering Shareholder”), regarding the Tendering Shareholder’s intention to tender all of the Target Company Stock held by it in the Tender Offer (the “Tender Agreement”). Upon the Tender Offer, The Yomiuri Shimbun Holdings made representation to the Tender Offeror that The Yomiuri Shimbun Holdings would tender all of the Target Company Stock held by it (together with the Target Company Stock held by the Tendering Shareholder, the “Prospective Tendered Shares”) in the Tender Offer. The Tender Offeror has not received any letter from The Yomiuri Shimbun Holdings of their intent to tender to the Tender Offer, and has not executed any contract in agreement to tender to the Tender Offer with The Yomiuri Shimbun Holdings.

If the total number of the share certificates, etc., tendered in the Tender Offer (“Tendered Share Certificates, Etc.”), is less than such minimum number, the Tender Offeror will not purchase, etc. any Tendered Share Certificates, Etc. However, the Tender Offeror aims to obtain all of the Target Company Stock in the Tender Offer (excluding the treasury shares held by the Target Company), and, therefore, has not set a maximum number of shares to be purchased, and, if the total number of Tendered Share Certificates, Etc. is equal to or greater than the minimum number, the Tender Offeror will purchase, etc. all of Tendered Share Certificates, Etc. The minimum number of the shares to be purchased (61,805,100 shares) exceeds the number of shares equivalent to the majority of the shares of the number of shares (88,386,882 shares), which is the total number of issued shares as of July 31, 2020, set forth in the Target Company Quarterly Report (95,857,420 shares) less the number of treasury shares held by the Target Company as of the same date set forth in the Target Company Quarterly Report) (3,149,736 shares) and the sum of the total of the Prospective Tendered Shares (4,320,802 shares), which is 44,193,442 shares (holding ratio: 47.67%) i.e., the majority of the number of Tender Offer Stock held by the shareholders of the Target Company who have no interest in the Tender Offeror, which is the number of shares (48,514,244 shares) exceeding the number equivalent to the so-called “majority of minority” plus the total of the Prospective Tendered Shares (4,320,802 shares). (Note 2) The minimum number of the shares to be purchased (61,805,100 shares) is the number of shares obtained by multiplying one unit (100 shares) of the Target Company Stock by the number of voting rights (618,051 rights) that is two-thirds of the voting rights or more (927,076 rights) of the number of shares (92,707,684 shares), which is the total number of issued shares as of July 31, 2020 set forth in the Target Company Quarterly Report (95,857,420 shares) less the number of treasury shares held by the Target Company as of the same date set forth in the Target Company Quarterly Report) (3,149,736 shares), which is 61,805,100 shares. As the Tender Offeror aims to make the Target Company a wholly-owned subsidiary of the Tender Offeror through the Tender Offer, if the Tender Offeror fails to acquire all of the Target Company Stock through 2 the Tender Offer (excluding the treasury shares held by the Target Company), the Tender Offeror intends to acquire all of the Target Company Stock by implementing the Procedures for Making the Target Company A Wholly-Owned Subsidiary as stated in “(4) Policy for Organizational Restructuring, Etc.
