The reductions in the amount of Share Capital and Legal Capital Surplus are accounting transfers within the net assets section of the balance sheet and do not change the amount of net assets of the Company.

The following are the details of the reductions in the amount of share capital and legal capital surplus: (x) the amount reduced from the Share Capital was JPY660,729,164, (y) the amount reduced from the Legal Capital Surplus was JPY715,749,163, and (z) the effective date of the reduction was September 30, 2025, Japan Standard Time.

To further enhance its corporate governance function, the Company proposed to abolish its Audit and Supervisory Board and establish an Audit and Supervisory Committee at its board of directors, as well as amending the Company’s articles of incorporation to effect the abolishment and the establishment.

Subject to Proposal 2’s approval, the Company proposed the election of Mr. Hiroshi Furukawa and Mr. Toshihito Kanai as directors who are not audit and supervisory committee members.

Subject to Proposal 2’s approval, the Company proposed the election of Mr. Hideaki Horikiri, Ms. Mutsuko Oba, and Mr. Yoshinari Noguchi as directors who are audit and supervisory committee members.

Subject to Proposal 2’s approval, the Company proposed the appointment of Nanatsu-boshi Audit Corporation as its accounting auditor as required by the Companies Act.

The Company proposed to establish the limit amount of annual aggregate remuneration of directors who are not audit and supervisory committee members at JPY200 million.

The Company proposed to establish the limit amount of annual aggregate remuneration of directors who are audit and supervisory committee members at JPY100 million.

In addition to Proposal 2, the Company proposed to, regarding the articles of incorporation, (i) amend Article 6 (Total number of authorized shares) to increase the number of authorized shares from 91,735,440 to 138,456,828, (ii) delete Article 18 (Measures for electronic information provision, etc.) as the Company is not regarded as a company that issues book-entry transfer shares (i.e., a listed company) in Japan, (iii) amend Article 25(Representative Directors and Directors with Specific Duties) to allow the Company’s board of directors to delegate all or part of the decision-making regarding important business operations to directors.

Proposal 3:

Proposal 4:

Termination of Audit and Supervisory Board and Establishment of the Audit and Supervisory Committee

On September 30, 2025, the shareholders approved the termination of the Company’s audit and supervisory board and the establishment of the audit and supervisory committee, a committee within the Company’s board of directors. As a result, the Company became a “company with audit and supervisory committee” under Japanese laws. With respect to the requirements of Rule 10A-3 under the Exchange Act and Nasdaq Rule 5600 relating to audit committees, the Company chose to rely on exemptions under these rules that are available to foreign private issuers with an audit and supervisory committee meeting certain requirements.

Directors who are audit and supervisory committee members are not required to be certified public accountants. Under the Companies Act, the majority of the members of the audit and supervisory committee must be outside directors as defined under the Companies Act, who have not served as executive directors, corporate executive officers, managers or any other type of employee for the Company or any of the Company’s subsidiaries for ten years prior to their election and fulfill certain other requirements specified in the Companies Act. The Company currently has an audit and supervisory committee consisting of three members, Hideaki Horikiri, Mutsuko Oba, and Yoshinari Noguchi. The Company believes that Mutsuko Oba and Yoshinari Noguchi are outside directors, causing the audit and supervisory committee to meet the requirements under the Companies Act.

The audit and supervisory committee oversees the Company’s accounting and financial reporting processes and the audits of the Company’s financial statements. An audit and supervisory committee member may note his or her opinion in the audit report issued by the audit and supervisory committee if such an opinion differs from that expressed in the audit report. The audit and supervisory committee is responsible for, among other things:

In addition to the Company’s audit and supervisory committee, the Company must appoint accounting auditors (kaikei kansa-nin) from independent certified public accountants or an independent audit firm in Japan. The accounting auditors have the statutory duties of examining the financial statements to be submitted to the shareholders by a representative director at the general meetings of shareholders and reporting their opinion thereon to the relevant directors and the audit and supervisory committee. The accounting auditors also audit the financial statements to be included in the securities reports that, if required, will be filed with the relevant local finance bureau of the Ministry of Finance. The Company has appointed Nanatsu-boshi Audit Corporation as its accounting auditor.

Issuance of the Company’s Common Shares to the Company’s Chief Financial Officer and Director

On December 30, 2025, the Company issued a press release to announce the issuance on the same date of 40,000,000 common shares (the “Shares”) of the Company to Hideaki Horikiri, the chief financial officer and a director of the Company, pursuant to that certain restricted common share compensation agreement (the “Compensation Agreement”) between the Company and Hideaki Horikiri, dated December 15, 2025. Pursuant to the Compensation Agreement, the issuance of the Shares was in consideration for Hideaki Horikiri’s services rendered and included a prohibition on any sale, transfer, loan or pledge of the Shares for a period of 20 years from the date of grant. However, the prohibition may be canceled by a resolution of the Company’s board of directors.

The execution of the Compensation Agreement and the issuance of Shares were authorized by the Company’s shareholder resolution and board of directors’ resolution dated September 30, 2025 and December 15, 2025, respectively. As of December 30, 2025, the common shares held by Hideaki Horikiri accounted for 53.6% of the Company’s outstanding 74,614,207 common shares.

A copy of the English translation of the Compensation Agreement and the press release are furnished in this report as Exhibits 10.1 and 99.1, respectively.
