**Execution of Definitive Agreement regarding Establishment of Joint Holding Company (Joint Share Transfer)**

**Between The Chiba Bank, Ltd. and The Chiba Kogyo Bank, Ltd.**

The Chiba Bank, Ltd. (President and Group Chief Executive Officer (CEO): Tsutomu Yonemoto; "**Chiba Bank**") and The Chiba Kogyo Bank, Ltd. (President (CEO) and Managing Executive Officer: Hitoshi Umeda; "**Chiba Kogyo Bank**") (Chiba Bank and Chiba Kogyo Bank are hereinafter collectively referred to as the "**Banks**") have proceeded with discussions toward the management consolidation between the Banks (the "**Management Consolidation**") based on the Memorandum of Understanding agreed upon between the Banks on September 29, 2025. At their respective boards of directors meetings held today, the Banks resolved (i) to establish a company named "Chiba Financial Group, Inc." (the "**Joint Holding Company**") as the wholly owning parent company of the Banks through a joint share transfer (the "**Share Transfer**") on April 1, 2027 (the "**Effective Date**"), subject to obtaining approval at the respective shareholders meetings of the Banks and authorizations and other permissions by relevant authorities and (ii) to approve the outline of the Joint Holding Company and the terms and other details of the Share Transfer, and the Banks entered into a certain management consolidation agreement as of today (the "**Management Consolidation Agreement**"). Accordingly, the Banks hereby announce as follows. The share transfer plan (the "**Share Transfer Plan**") pertaining to the Share Transfer is scheduled to be prepared on September 30, 2026 (for details, please refer to Section 2. (1) "Schedule for the Share Transfer" below).

Details

&nbsp;&nbsp;&nbsp;&nbsp;1. Outline of the Management Consolidation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Background to the Management Consolidation

As previously announced in the press release entitled, "Memorandum of Understanding regarding Management Consolidation Between The Chiba Bank, Ltd. and The Chiba Kogyo Bank, Ltd." dated September 29, 2025, the Banks established a preparatory committee on the management consolidation and proceeded with discussions and deliberations toward establishing the Joint Holding Company through a share transfer on or around April 1, 2027.

The Banks, as regional financial institutions both headquartered in Chiba Prefecture, consider their value to lie in contributing to solving regional challenges and fostering the sustainable growth of the region. Chiba Bank has defined its purpose as "Create a local community better suited to bringing each person's hope to life" and Chiba Kogyo Bank has defined its purpose as "Create a thousand happinesses by always being there for our customers and community. Today, and for every tomorrow.", and the Banks have been working on various regional initiatives, either individually or occasionally in collaboration with each other.

Chiba Prefecture is located in the Tokyo metropolitan area and offers excellent access to the city center and abundant employment opportunities. The urban development around Narita Airport has established it as an international business hub, while the expansion of transportation networks such as the Metropolitan Inter-City Expressway (Ken-O Expressway) has further enhanced the flow of people and goods. Furthermore, Chiba Prefecture boasts premier national rankings in terms of prefectural gross domestic product, commerce, industry, agriculture, and even fisheries. It is also actively leveraging its tourism resources, capitalizing on its rich natural environment and warm climate.

On the other hand, customer values have become increasingly complex and diverse, their behavioral patterns have significantly changed, and social structure is undergoing major changes—including advances in digital technology, growing interest in sustainability, the impact of soaring raw material prices and worsening labor shortages. As a result, the needs of the regional community and the challenges that need to be addressed are becoming increasingly diverse and complex.

Furthermore, the long-standing policy of monetary easing undergoes significant review and competition in the financial sector is expected to intensify with the arrival of a "world with positive interest rates." Additionally, the pace of technological innovation, including generative AI, is accelerating, and companies from other industries are increasingly entering the financial sector to pursue business opportunities, resulting in a rapidly changing business environment.

In light of these changes in the business environment, the Banks have deepened their shared understanding that further strengthening their management foundations is essential in order to continue providing stable and sophisticated financial services to the regional economy and their customers over the long term.

At a meeting of the preparatory committee on management consolidation, the Banks determined that, in order to further contribute to the sustainable growth of their customers and the region and to help address the increasingly complex regional challenges, the Management Consolidation between the Banks, both of which have their respective regional bases in Chiba Prefecture, will contribute to the further development of Chiba Prefecture's economy, the realization of the purposes of the Banks, and the enhancement of their corporate value. Accordingly, today, the Banks reached a definitive agreement on the implementation of the management consolidation through the establishment of the Joint Holding Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Objectives of the Management Consolidation

The aim of the Management Consolidation is for the Banks, both of which already possess customer bases in Chiba Prefecture and the Tokyo metropolitan area, to "step up" to a new banking group for the region.

In the Management Consolidation, the Banks will work to respect each other's operational autonomy and self-reliance to the maximum extent, and to engage in discussions and deliberations aimed at "strengthening regional financial capabilities through two brands built on mutual trust and respect." In today's business environment, where customer needs and challenges to be addressed are diversifying and becoming more complex, the Banks will enhance and diversify the solutions offered to customers while pursuing productivity and efficiency through deepening of collaborative relationships that leverage the Banks' customer relationships and the Banks' autonomy, mutual utilization of the Banks' respective strengths in products, services, and expertise, and by leveraging each other's management resources as their customer bases expand. Through these measures, the Banks will provide customers and the community with a better customer experience and greater added value.

In addition, amid intensifying competition in the financial sector to enhance service convenience driven by technological innovation in financial services and cross-industry expansion, the Banks believe it is essential to secure diverse personnel that enable to handle issues in value creation fields and specialized fields. Through sharing management resources of the Banks, and fostering talent by sharing knowledge, experience, and expertise in accordance with mutual trust and respect, the Banks will create new growth opportunities for employees and build a system where each employee can maximize their abilities and shine in their own way in addition to secure professional personnel.

Furthermore, as strengthening resilience—including measures against financial crimes and cybersecurity—becomes increasingly vital to ensure that customers can use our services safely and securely, the Banks strongly recognize that their responsibility to provide financial infrastructure is now more significant than ever before and they consider it their social mission to contribute to the maintenance and development of a stable and sound regional financial system. By leveraging the complementary strengths and networks of the Banks within Chiba Prefecture and ensuring the stability of the regional economy through the continued operation and further strengthening of a sound regional financial system, the Banks will contribute to the sustainable development of the regional community.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Synergies anticipated from the Management Consolidation

Chiba Bank has developed advanced alliance strategies across various domains, including businesses, system administration, and the utilization of digital tools, through initiatives such as the TSUBASA Alliance launched in 2015, the Chiba-Musashino Alliance launched in 2016, the Chiba-Yokohama Partnership launched in 2019, and the business collaboration with Sony Bank Inc. that commenced in 2022.

Chiba Kogyo Bank has accumulated various expertise related to collaboration with other banks through initiatives such as the FinX Partnership launched in May 2018, aiming to advance digitalization through collaboration and cooperation, and focusing management resources on strategic areas through the development of an accounting system platform at the Regional Bank Integrated Service Center, which Chiba Kogyo Bank and 12 other regional banks have joined.

By utilizing such experience and expertise related to alliances and collaboration with other banks, the Banks will proceed with specific measures in the future with a focus on the following synergies in order to achieve the objectives of the Management Consolidation as soon as possible, contribute to the sustainable growth of the regional economy, and maximize their corporate value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Provide the customers and the community with a better customer experience

By strengthening their sales capabilities and expanding their sales channels through mutually leveraging each other's customer relationships, expertise, information, and other strengths that the Banks have cultivated at their bases in Chiba Prefecture, as well as by enhancing and diversifying their products and services through strengthening their ability to respond to customer needs and issues, the Banks strive to provide their customers and the region with a better customer experience and added value, thereby aiming to further expand the Banks' top-line revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Streamlining through sharing management resources and overall optimization

In addition to optimizing overlapping headquarter functions and consolidating back-office operations, the Banks are proceeding with discussions and deliberations towards the integration of their core systems in order to build a more efficient system architecture. The Banks aim to achieve cost reductions through these initiatives and other measures, and further growth through investing the Banks' management resources in growth areas and entering new business domains by leveraging their knowledge, experience, and expertise.

(Note 1) The Share Transfer Plan is scheduled to be prepared on September 30, 2026. The names of the directors at incorporation of the Joint Holding Company other than the representative directors at incorporation of the Joint Holding Company are expected to be determined when the Share Transfer Plan is prepared. However, the terms and conditions related to the Share Transfer are not expected to differ from those described in this press release. The representative directors of the Joint Holding Company at incorporation thereof are described in Section 5. (4) "Representatives and officers expected to assume office" below.

(Note 2) The above schedule may be changed upon consultation between the Banks where necessary in the course of moving towards the Share Transfer or for other reasons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Method of the Share Transfer

The Share Transfer will take the form of a joint share transfer, under which the Banks will become wholly owned subsidiaries of the Joint Holding Company to be incorporated following the Share Transfer and the Joint Holding Company will become the wholly owning parent company of the Banks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Details of allotment in the Share Transfer (share transfer ratio)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Common stock

Company Name <u>Chiba Bank</u> <u>Chiba Kogyo Bank</u> <br> <u>Share transfer ratio</u> <u>1</u> <u>1</u>

(Note 1) Details of allotment of shares pertaining to the Share Transfer

One share of common stock of the Joint Holding Company will be allocated and delivered for each share of common stock of Chiba Bank, and 1 share of common stock of the Joint Holding Company will be allocated and delivered for each share of common stock of Chiba Kogyo Bank. If the number of shares of common stock of the Joint Holding Company which will be delivered to a shareholder of the Banks through the Share Transfer includes a fraction of less than one share, the Joint Holding Company will, pursuant to Article 234 of the Companies Act of Japan and other applicable laws and regulations, pay the relevant shareholder a cash amount corresponding to such fractional share. The above share transfer ratio may be changed upon discussions between the Banks in the event that significant changes occur in the terms and conditions on which the calculation is based.

(Note 2) Number of shares unit of the Joint Holding Company and handling of shares constituting less than one unit

The number of shares unit of the Joint Holding Company shall be 100 shares.

The Banks' shareholders who receive an allocation of shares of common stock constituting less than one unit (100 shares) of the Joint Holding Company ("**Shares Constituting Less than One Unit**") through the Share Transfer may not sell their Shares Constituting Less than One Unit on the Tokyo Stock Exchange or any other securities exchange. Shareholders who hold the Shares Constituting Less than One Unit may request the Joint Holding Company to purchase their Shares Constituting Less than One Unit pursuant to the provisions of Article 192, paragraph (1) of the Companies Act. In addition, it is expected that such shareholders may request the Joint Holding Company to sell the number of shares needed, together with the number of Shares Constituting Less than One Unit held by them, to constitute one unit pursuant to the provisions of Article 194, paragraph (1) of the Companies Act and the provisions to be stipulated in the Articles of Incorporation of the Joint Holding Company.

(Note 3) Number of new shares to be delivered by the Joint Holding Company through the Share Transfer (Expected)

Common stock: 867,743,132 shares

The number of shares specified above is calculated based on the total number of issued common shares of Chiba Bank (805,521,087 shares as of December 31, 2025) and the total number of issued common shares of Chiba Kogyo Bank (62,222,045 shares as of December 31, 2025). However, prior to the Effective Date of the Share Transfer, the Banks may cancel the treasury shares which are currently held or may thereafter be newly acquired by them, within the range of such treasury shares that can be canceled in practice, and the number of new shares to be issued by the Joint Holding Company is subject to change. The number of new shares specified above does not include the number of shares of common stock of the Joint Holding Company to be issued to the shareholders of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock and 2nd Series of Class 7 Preferred Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) 2nd Series of Class 6 Preferred Stock

In the share transfer of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock, the variable share transfer ratio method has been adopted. Under the variable share transfer ratio method, the value of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock will be determined on the date when the Board of Directors of the Banks resolved to conclude the Management Consolidation Agreement (the "Share Transfer Decision Time"), and the number of shares of common stock of the Joint Holding Company to be allotted as consideration for each share of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock will be determined based on the average stock price of Chiba Bank's common stock for a certain period of time immediately preceding the Effective Date

In the share transfer of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock, the Joint Holding Company shall allocate to shareholders of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock as of the time immediately preceding the acquisition of all issued shares of the Banks (the "Record Time"), in lieu of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock, the number of shares of its common stock obtained by multiplying the number of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock owned by those shareholders, by the share transfer ratio calculated by the following formula:

Share transfer ratio = 20,000 yen / Average stock price of Chiba Bank's common stock

(Note 1) Method of calculating the share transfer ratio

The share transfer ratio is calculated to the third decimal place and rounded to the second decimal place. The average stock price of Chiba Bank's common stock will be the simple average (calculated to the first decimal place and rounded to the nearest whole number) of the closing price per share of Chiba Bank common stock of each trading day between March 5, 2027 and March 18, 2027 (however, excluding days on which no trading has taken place), on the Prime Market of the Tokyo Stock Exchange, with the period required for taking administrative measures being set.

(Note 2) Number of new shares to be delivered by the Joint Holding Company through the Share Transfer (Expected)

The Joint Holding Company will deliver the number of shares of its common stock obtained by multiplying the total number of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock owned by shareholders of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock, by the above-stated share transfer ratio. In the event that the number of shares of common stock of the Joint Holding Company to be delivered to shareholders of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock is less than one share as a result of the Share Transfer, the relevant shareholders will be paid an amount corresponding to the fractional portion of less than one share in accordance with the provisions of Article 234 of the Companies Act and other relevant laws and regulations.

(Note 3) Handling of shares that are less than one unit

Shareholders of the Banks who will be allotted shares that are less than one unit as a result of the Share Transfer may not sell these shares on the Tokyo Stock Exchange or other financial instruments exchanges; however, those shareholders who will hold such shares may request the Joint Holding Company to purchase them pursuant to Article 192, Paragraph 1 of the Companies Act. In addition, pursuant to Article 194, Paragraph 1 of the Companies Act and the provisions to be set forth in the Articles of Incorporation of the Joint Holding Company, it will also be possible for them to request the Joint Holding Company to sell the number of shares that amount to one unit together with the number of their shares that are less than one unit.

In the case of ordinary share transfers, the share transfer ratio and the number of shares of the relevant wholly owning parent company established by the share transfer to be delivered to shareholders of the relevant wholly owned subsidiary in the share transfer as consideration, are determined at the time of concluding and publicly announcing the share transfer plan (the "Announcement Time"). Therefore, at the Announcement Time, the value of the shares of the wholly owning parent company established by the share transfer that the shareholders of the wholly owned subsidiary in the share transfer will eventually own on the effective date of the share transfer will not be determined, and will fluctuate depending on the stock price trend of the shares of the wholly owned subsidiary in the share transfer between the Announcement Time and the effective date of the share transfer. Conversely, under the variable share transfer ratio method, the fair value of the shares of the wholly owned subsidiary in the share transfer will be determined at the Announcement Time, and the number of shares of the wholly owning parent company established in the share transfer to be delivered as consideration for each share of the wholly owned subsidiary will be determined by dividing the said fair value by the average stock price of the wholly owned subsidiary during a certain period immediately before the effective date of the share transfer. As a result, shareholders of the wholly owned subsidiary in the share transfer will be able to receive common stock of the wholly owning parent company established in the share transfer equivalent to the fair value of shares of that subsidiary, based on the market price immediately preceding the effective date of the share transfer. Therefore, compared to an ordinary share transfer, in which the number of shares of the wholly owning parent company to be received by shareholders of the wholly owned subsidiary based on the market price immediately preceding the date of execution of the share transfer plan, the period during which the value of the shares of the wholly owning parent company to be owned by shareholders of the wholly owned subsidiary on the effective date of the share transfer will fluctuate due to stock price trends up to the effective date of the share transfer will be shortened, and it is expected to approximate the value of the shares of the wholly owned subsidiary in the share transfer. After verifying these characteristics, the Banks carefully discussed which method is the most appropriate method to adopt, taking into consideration the fact that Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock is unlisted stock, to which a provision it attached that allows Chiba Kogyo Bank to acquire an amount equivalent to the amount paid (20,000 yen) for each share of the 2nd Series of Class 6 Preferred Stock after a certain period of time. As a result, the Banks determined it appropriate to have the value of common stock of the Joint Holding Company which shareholders of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock will finally come to own as of the Effective Date to be approximate to the above-stated value of Chiba Kogyo Bank's 2nd Series of Class 6 Preferred Stock (20,000 yen per share) and finally decided to adopt the variable share transfer ratio method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) 2nd Series of Class 7 Preferred Stock

In the share transfer of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock, the variable share transfer ratio method has been adopted. Under the variable share transfer ratio method, the value of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock will be determined at the Share Transfer Decision Time, and the number of shares of common stock of the Joint Holding Company to be allotted as consideration for each share of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock will be determined based on the average stock price of Chiba Bank's common stock for a certain period of time immediately preceding the Effective Date

In the share transfer of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock, the Joint Holding Company shall allocate to shareholders of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock as of the Record Time, in lieu of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock, the number of shares of its common stock obtained by multiplying the number of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock owned by those shareholders, by the share transfer ratio calculated by the following formula:

Share transfer ratio = 500,000 yen / Average stock price of Chiba Bank's common stock

(Note 1) Method of calculating the share transfer ratio

The share transfer ratio is calculated to the third decimal place and rounded to the second decimal place. The average stock price of Chiba Bank's common stock will be the simple average (calculated to the first decimal place and rounded to the nearest whole number) of the closing price per share of Chiba Bank common stock of each trading day between March 5, 2027 and March 18, 2027 (however, excluding days on which no trading has taken place), on the Prime Market of the Tokyo Stock Exchange, with the period required for taking administrative measures being set.

(Note 2) Number of new shares to be delivered by the Joint Holding Company through the Share Transfer (Expected)

The Joint Holding Company will deliver the number of shares of its common stock obtained by multiplying the total number of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock owned by shareholders of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock, by the above-stated share transfer ratio. In the event that the number of shares of common stock of the Joint Holding Company to be delivered to shareholders of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock is less than one share as a result of the Share Transfer, the relevant shareholders will be paid an amount corresponding to the fractional portion of less than one share in accordance with the provisions of Article 234 of the Companies Act and other relevant laws and regulations.

(Note 3) Handling of shares that are less than one unit

Shareholders of the Banks who will be allotted shares that are less than one unit as a result of the Share Transfer may not sell these shares on the Tokyo Stock Exchange or other financial instruments exchanges; however, those shareholders who will hold such shares may request the Joint Holding Company to purchase them pursuant to Article 192, Paragraph 1 of the Companies Act. In addition, pursuant to Article 194, Paragraph 1 of the Companies Act and the provisions to be set forth in the Articles of Incorporation of the Joint Holding Company, it will also be possible for them to request the Joint Holding Company to sell the number of shares that amount to one unit together with the number of their shares that are less than one unit.

In the case of ordinary share transfers, the share transfer ratio and the number of shares of the relevant wholly owning parent company established by the share transfer to be delivered to shareholders of the relevant wholly owned subsidiary in the share transfer as consideration, are determined at the Announcement Time. Therefore, at the Announcement Time, the value of the shares of the wholly owning parent company established by the share transfer that the shareholders of the wholly owned subsidiary in the share transfer will eventually own on the effective date of the share transfer will not be determined, and will fluctuate depending on the stock price trend of the shares of the wholly owned subsidiary in the share transfer between the Announcement Time and the effective date of the share transfer. Conversely, under the variable share transfer ratio method, the fair value of the shares of the wholly owned subsidiary in the share transfer will be determined at the Announcement Time, and the number of shares of the wholly owning parent company established in the share transfer to be delivered as consideration for each share of the wholly owned subsidiary will be determined by dividing the said fair value by the average stock price of the wholly owned subsidiary during a certain period immediately before the effective date of the share transfer. As a result, shareholders of the wholly owned subsidiary in the share transfer will be able to receive common stock of the wholly owning parent company established in the share transfer equivalent to the fair value of shares of that subsidiary, based on the market price immediately preceding the effective date of the share transfer. Therefore, compared to an ordinary share transfer, in which the number of shares of the wholly owning parent company to be received by shareholders of the wholly owned subsidiary based on the market price immediately preceding the date of execution of the share transfer plan, the period during which the value of the shares of the wholly owning parent company to be owned by shareholders of the wholly owned subsidiary on the effective date of the share transfer will fluctuate due to stock price trends up to the effective date of the share transfer will be shortened, and it is expected to approximate the value of the shares of the wholly owned subsidiary in the share transfer. After verifying these characteristics, the Banks carefully discussed which method is the most appropriate method to adopt, taking into consideration the fact that Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock is unlisted stock, to which a provision it attached that allows Chiba Kogyo Bank to acquire an amount equivalent to the amount paid (500,000 yen) for each share of the 2nd Series of Class 7 Preferred Stock after a certain period of time. As a result, the Banks determined it appropriate to have the value of common stock of the Joint Holding Company which shareholders of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock will finally come to own as of the Effective Date to be approximate to the above-stated value of Chiba Kogyo Bank's 2nd Series of Class 7 Preferred Stock (500,000 yen per share) and finally decided to adopt the variable share transfer ratio method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Handling of stock acquisition rights and bonds with stock acquisition rights of the wholly owned subsidiaries
in connection with the Share Transfer

In connection with the Share Transfer, the Joint Holding Company will allocate and deliver to the holders of stock acquisition rights issued by Chiba Kogyo Bank outstanding as of the record time, stock acquisition rights of the Joint Holding Company in substitute for the stock acquisition rights they hold, based on the terms of stock acquisition rights and the share transfer ratio. Chiba Bank has not issued stock acquisition rights and neither of the Banks has issued bonds with stock acquisition rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Dividends and other related matters of the Banks based on the record date prior to the establishment of
the Joint Holding Company

During the fiscal year ending March 2027, Chiba Bank may distribute dividends of surplus, announce its dividend forecast based on its policy of maintaining a dividend payout ratio of 40% or higher for such fiscal year, and that it may flexibly repurchase treasury stock within the range of required capital level.

During the fiscal year ending March 2027, Chiba Kogyo Bank may distribute dividends of surplus and announce its dividend forecast, up to 20 yen per share of its common stock, and that, with respect to its preferred stock, it may distribute dividends of surplus and announce its dividend forecast, based on the terms of such preferred stock.

&nbsp;&nbsp;&nbsp;&nbsp;3. Grounds for details of allotment pertaining to the Share Transfer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Basis and reasons for the details of allotment

As described under Section 1. "Outline of the Management Consolidation" above, based on the Memorandum of Understanding concerning deliberations of the Management Consolidation entered into on September 29, 2025 between the Banks, the Banks established the preparatory committee on the management consolidation and have been discussing and deliberating consummation of the management consolidation through the incorporation of the Joint Holding Company under a share transfer on or around April 1, 2027.

As described in "3. (4) Measures to ensure fairness" below, Chiba Bank appointed Mitsubishi UFJ Morgan Stanley Securities Co., Ltd. ("**Mitsubishi UFJ Morgan Stanley Securities**") as an independent third-party appraiser and Nagashima Ohno & Tsunematsu as a legal advisor in order to ensure the fairness of the consideration for the Share Transfer and of other aspects of the Share Transfer, and commenced deliberations with respect to the Share Transfer. After careful discussions and deliberations with reference to the analysis prepared by Mitsubishi UFJ Morgan Stanley Securities and the advice provided by Nagashima Ohno & Tsunematsu, Chiba Bank concluded that it is appropriate to implement the Share Transfer based on the share transfer ratio indicated in Section 2. (3) "Details of allotment in the Share Transfer (share transfer ratio)" above.

On the other hand, as described in "3. (4) Measures to ensure fairness" below, Chiba Kogyo Bank appointed Mizuho Securities Co., Ltd. ("**Mizuho Securities**") as an independent third-party appraiser and Nishimura & Asahi as a legal advisor in order to ensure the fairness of the consideration for the Share Transfer and of other aspects of the Share Transfer, and commenced deliberations with respect to the Share Transfer. After careful discussions and deliberations with reference to the analysis prepared by Mizuho Securities and the advice provided by Nishimura & Asahi, Chiba Kogyo Bank concluded that it is appropriate to implement the Share Transfer with the share transfer ratio indicated in Section 2. (3) "Details of allotment in the Share Transfer (share transfer ratio)" above.

As described above, the Banks carefully negotiated and discussed the share transfer ratio, comprehensively taking into account factors such as the market share price, financial position, and future prospects of the Banks, based on the results of the due diligence conducted by each of the Banks on the other, with each of the Banks making reference to the calculation and analysis by its third-party appraiser, and the legal advice of its legal advisor. As a result of such negotiations and discussions, the Banks concluded that the share transfer ratio is appropriate, and at their respective boards of directors' meetings held today, the Banks resolved to determine and agreed on the share transfer ratio for the Share Transfer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Matters concerning calculation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Common stock

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Names of the appraisers and relationship with the Banks

Mitsubishi UFJ Morgan Stanley Securities, a financial advisor (third-party appraiser) of Chiba Bank, is not a related party of either the Banks and it does not have any material interest requiring disclosure in regard to the Share Transfer. The remuneration to be paid to Mitsubishi UFJ Morgan Stanley Securities in connection with the Share Transfer includes a contingency fee that is to be paid subject to conditions that include the successful completion of the Share Transfer. However, Chiba Bank has determined that the inclusion of this contingency fee does not prevent independence, taking into account the general practice in similar cases. Thus, Chiba Bank appointed Mitsubishi UFJ Morgan Stanley Securities as a third-party appraiser based on the aforementioned remuneration system.

Mizuho Securities, a financial advisor (third party appraiser) of Chiba Kogyo Bank, is not a related party of Chiba Bank. Mizuho Securities, Mizuho Bank, Ltd. ("Mizuho Bank"), and Mizuho Trust & Banking Co., Ltd. ("Mizuho Trust Bank"), which are group companies of Mizuho Securities, have the status of shareholders of Chiba Kogyo Bank; however, they do not have any material interest that will constitute a conflict of interest in the Share Transfer. According to Mizuho Securities, pursuant to Article 36 of the Financial Instruments and Exchange Act (Act No. 25 of 1948; as amended) and

Article 70-4 of the Cabinet Office Order on Financial Instruments Business (Cabinet Office Order No. 52 of 2007; as amended), Mizuho Securities has an appropriate conflict of interest management system in place, which includes information barrier measures between Mizuho Securities' financial advisory services department and another department of Mizuho Securities that holds shares in Chiba Kogyo Bank, as well as between Mizuho Securities on one side and Mizuho Bank and Mizuho Trust Bank on the other side. Through these measures, Mizuho Securities calculated the share transfer ratio from a standpoint independent of Mizuho Securities, Mizuho Bank, and Mizuho Trust Bank in their respective capacities as shareholders of Chiba Kogyo Bank. Chiba Kogyo Bank appointed Mizuho Securities as a third-party appraiser independent of the Banks, as appropriate measures to prevent harmful effects have been implemented within Mizuho Securities and between Mizuho Securities on one side, and Mizuho Bank and Mizuho Trust Bank on the other side.

The remuneration to be paid to Mizuho Securities in connection with the Share Transfer includes a contingency fee that is to be paid subject to conditions that include the successful completion of the Share Transfer. However, Chiba Kogyo Bank has determined that the inclusion of this contingency fee does not prevent independence, taking into account the general practice in similar cases. Thus, Chiba Kogyo Bank appointed Mizuho Securities as a third-party appraiser based on the aforementioned remuneration system.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Outline of the calculation

In order to ensure fairness in calculating the share transfer ratio used for the Share Transfer, Chiba Bank appointed Mitsubishi UFJ Morgan Stanley Securities and Chiba Kogyo Bank appointed Mizuho Securities as their respective third-party appraisers for calculating and analyzing the share transfer ratio.

Mitsubishi UFJ Morgan Stanley Securities conducted the market share price analysis, because the shares of the Banks are listed on a financial instruments exchange and market prices are available for their shares, as well as the comparable peer company multiple analysis, because there exist multiple listed peer companies that are comparable to each of the Banks and Mitsubishi UFJ Morgan Stanley Securities was able to estimate share value of each of the Banks using the comparable peer company multiple analysis. Furthermore, in order to reflect the status of future business activities in the valuation, Mitsubishi UFJ Morgan Stanley Securities conducted the dividend discount model analysis (the "**DDM Analysis**")

In the market share price analysis, Mitsubishi UFJ Morgan Stanley Securities used March 24, 2026 as the reference date, and used the closing price on the reference date on the Tokyo Stock Exchange and the simple average of the closing prices on each trading day for the past 1 month, 3 months and 6 months prior to the reference date.

The calculation of share value in the DDM Analysis is based on various factors, including the profits in the financial projections and investment plans presented by the management of the Banks, which the Banks agreed to use for the calculation purpose; the results of due diligence conducted on the Banks; and other publicly available information and material.

The financial projections of Chiba Kogyo Bank used by Mitsubishi UFJ Morgan Stanley Securities as a basis for the DDM Analysis include a fiscal year in which significant increases or decreases in profit are expected. Specifically, an increase in interest income from loans is expected for the fiscal year ending March 2028, which is expected to result in a significant increase in profit attributable to owners of parent. The financial projections of Chiba Bank do not include any fiscal years in which significant increases or decreases in profit are expected.

The results of the calculations under each analysis above are indicated below. The results of the calculations of the share transfer ratio below represent the number of common shares of the Joint Holding Company to be allotted for one common share of Chiba Kogyo Bank, assuming that one common share of the Joint Holding Company is allotted for one common share of Chiba Bank.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(Note) The analysis by Mitsubishi UFJ Morgan Stanley Securities and the analysis of the underlying share transfer
ratio were provided to Chiba Bank for its reference. Such analysis does not constitute a financial opinion
or recommendation of Mitsubishi UFJ Morgan Stanley Securities or its affiliates, nor does it constitute an approval of the Share Transfer,
or an opinion or recommendation to the shareholders of Chiba Bank or Chiba Kogyo Bank or any other person regarding the transfer and acquisition
of shares or the exercise of shareholder rights, including the exercise of voting rights, or consent to the Share Transfer or any other
related matters. Mitsubishi UFJ Morgan Stanley Securities relied on information that was already publicly disclosed or provided or otherwise
made available to it by Chiba Bank or Chiba Kogyo Bank for the analysis and calculation of the share transfer ratio on the assumption
that such information is accurate and complete, and Mitsubishi UFJ Morgan Stanley Securities has not independently verified the accuracy
or completeness thereof. Also, Mitsubishi UFJ Morgan Stanley Securities assumed that the financial projections were reasonably prepared
by the management of the Banks to reflect the best estimates and judgements available at the time they were provided
with respect to the future financial condition of the Banks. Mitsubishi UFJ Morgan Stanley Securities is not a legal,
accounting or tax adviser. Mitsubishi UFJ Morgan Stanley Securities acted as financial adviser to Chiba Bank in connection with the Share
Transfer and relied on the determinations of Chiba Bank and Chiba Bank's legal, accounting and tax advisers for issues relating to legal,
accounting, and tax matters without independently verifying them. Mitsubishi UFJ Morgan Stanley Securities has not made or obtained any
independent assessment or appraisal of the assets and liabilities (including off-balance sheet assets and liabilities and other contingent
liabilities) of Chiba Bank, Chiba Kogyo Bank or their affiliates, nor has it requested any third-party institution to value or appraise
them. Mitsubishi UFJ Morgan Stanley Securities' analysis is based on economic, financial, market, and other conditions as of the
reference date of the share transfer ratio calculation report and on information made available to Mitsubishi UFJ Morgan Stanley Securities
as of such reference date. Although there is a possibility that an event occurring on or after the reference date may affect the basis
on which the Mitsubishi UFJ Morgan Stanley Securities' analysis and the share transfer ratio calculation report have been prepared,
Mitsubishi UFJ Morgan Stanley Securities is not obligated to update, revise or reconfirm the share transfer ratio calculation report or
its analysis. In addition, the preparation of the share transfer ratio calculation report and the underlying analysis therefor was a complex
process and is not necessarily suitable for partial analysis or summary description. The valuation ranges based on the specific analysis
described herein may not be considered as Mitsubishi UFJ Morgan Stanley Securities' assessment of the actual value of Chiba Bank
or Chiba Kogyo Bank.

In calculating the share transfer ratio, Mizuho Securities conducted the average market price method, because the shares of the Banks are listed on the Prime Market of the Tokyo Stock Exchange and market prices are available for their shares, as well as the comparable company analysis, because there exist multiple listed companies that are comparable to each of the Banks and Mizuho Securities was able to estimate share value of each of the Banks using the comparable multiple valuation method. Furthermore, in order to reflect the status of future business activities in the valuation, Mizuho Securities conducted the dividend discount model method (the "**DDM Method**"), which is a method used to analyze the share value by discounting to its present value the cash flows attributable to the shareholders after taking into account retained earnings and other factors necessary to maintain a certain capital structure, using cost of capital, and is a method used generally for the analysis of financial institutions. The results of the calculations under each method above are indicated below. The calculated ranges for the share transfer ratio below represent the number of common shares of the Joint Holding Company to be allotted for one common share of Chiba Kogyo Bank, assuming that one common share of the Joint Holding Company is allotted for one common share of Chiba Bank.

| &nbsp;&nbsp;3 | &nbsp;&nbsp;DDM Method | &nbsp;&nbsp;0.74 - 1.57 |

---

Under the average market price method, Mizuho Securities used March 24, 2026 as the reference date and calculated the share transfer ratio based on (i) the closing price of the shares on the Tokyo Stock Exchange on that date, and (ii) the simple average of the closing prices over the 1 month, 3 months and 6 months periods preceding the reference date.

The future profit plans of Chiba Kogyo Bank used by Mizuho Securities as a basis for the DDM Method include a fiscal year in which significant increases or decreases in profit are expected. Specifically, an increase in interest income from loans is expected for the fiscal year ending March 2028, which is expected to result in a significant increase in profit attributable to owners of parent. Furthermore, the future profit plans of Chiba Bank do not include any fiscal years in which significant increases or decreases in profit are expected.

In calculating the share transfer ratio, Mizuho Securities in principle used as-is material and information provided by the Banks as well as publicly available information and other data. Mizuho Securities assumed and relied on the accuracy and completeness of all material, information and other data that Mizuho Securities reviewed or analyzed, and did not independently verify or assume any obligation to independently verify the accuracy or completeness of such material and information. Mizuho Securities did not undertake an independent evaluation, appraisal or assessment of any of the assets or liabilities (including, but not limited to, financial derivative products, off-balance-sheet assets and liabilities, and other contingent liabilities), on an aggregate or individual basis, of the Banks or any of their respective affiliates, nor did Mizuho Securities make any request to a third party for any such valuation, appraisal or assessment. Mizuho Securities assumed that the business plans, financial projections, and other forward-looking information provided by each of the Banks were reasonably prepared based on the best possible forecasts and judgments currently available to the respective management of the Banks.
