**Notice Regarding the Execution of the Business Integration Agreement and Share Exchange Agreement Between OLBA HEALTHCARE HOLDINGS, Inc. and DVx Inc.; in Association Therewith, Changes in its Trade Name and Partial Amendment of the Articles of Incorporation, Change in the Representative Director Thereof, Changes in its Subsidiaries, Major Shareholders and Largest Major Shareholder; as well as Changes in Parent Company, Major Shareholders and Largest Major Shareholder and Parent Company of DVx Inc.**

OLBA HEALTHCARE HOLDINGS, Inc. ("**OLBA HEALTHCARE**") and DVx Inc. ("**DVx**") (OLBA HEALTHCARE and DVx collectively, "**Both Companies**") hereby announce that they have resolved at the meetings of their respective Boards of Directors held today, to execute a share exchange (the "**Share Exchange**") for the business integration based on the spirit of equal partnership between Both Companies (the "**Business Integration**"), under which OLBA HEALTHCARE will become the wholly owning parent company resulting from the Share Exchange and DVx will become the wholly owned subsidiary company resulting therefrom, and Both Companies have executed today an agreement on the Business Integration (the "**Business Integration Agreement**") and an agreement on the Share Exchange (the "**Share Exchange Agreement**") between Both Companies, the details of which are described below.

In accordance with the foregoing, Both Companies hereby also provide notice that OLBA HEALTHCARE has informally determined to change its representative director, effective as of the Effective Date.

Details

&nbsp;&nbsp;&nbsp;&nbsp;**I.** **Business Integration** 

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Purpose of Business Integration** 

OLBA HEALTHCARE was established in October 1967 as Kawanishi Medical Equipment Co., Ltd., with the aim to sell medical and scientific instruments, which later, in January 2021, changed its trade name to OLBA HEALTHCARE HOLDINGS, Inc., in celebration of its 100th year in business. Also, OLBA HEALTHCARE listed its common shares (the "**OLBA HEALTHCARE Shares**") on the Second Section of the Tokyo Stock Exchange in December 2000, and on the First Section of the Tokyo Stock Exchange in March 2020, which underwent a transition to the Tokyo Stock Exchange Standard Market due to a review of classification of markets at the Tokyo Stock Exchange in April 2022, and the OLBA HEALTHCARE Shares have been listed thereon up to the present date.

OLBA HEALTHCARE, as a corporate group (the "**OLBA HEALTHCARE Group**"), which, as of today, comprises nine companies consisting of OLBA HEALTHCARE, a holding company, and its eight consolidated subsidiaries, engages, primarily in the Chugoku-Shikoku region in Japan, in business pertaining to medical equipment involving the wholesale distribution of medical devices and related instruments, in SPD business services involving administration of goods/information and purchasing control, as well as the business of nursing care products involving distribution and rental of beds for home-care use and nursing care products.

Meanwhile, DVx was founded in April 1986 as Hertz Corporation for the purpose of sales of cardiac pacemakers and follow-up business, which later changed its trade name in February 2004 to DVx Inc. Also, DVx listed the DVx Shares on the Jasdaq Securities Exchange, Inc. in April 2007, on the Second Section of the Tokyo Stock Exchange in December 2013, and on the First Section of the Tokyo Stock Exchange in September 2014, which, thereafter, underwent a transition to the Tokyo Stock Exchange Standard Market due to a review of classification of markets at the Tokyo Stock Exchange in April 2022, and the DVx Shares have been listed thereon up to the present date.

DVx, as a corporate group (the "**DVx Group**;" collectively the OLBA HEALTHCARE Group and DVx Group are referred to as the "**Groups of Both Companies**"), as of today, comprising the two companies of DVx and its consolidated subsidiary, engages, primarily in the Kanto region of Japan, in the arrhythmia business, selling, as a distribution agent, medical equipment for examination and treatment of arrhythmia, the ischemic disease business, selling, as a distribution agent/sole agency in Japan, medical equipment for examination and treatment of ischemic symptoms and the business of distribution of other medical devices and related instruments.

Both Companies recognize that the business environment surrounding the business field of the wholesale industry has grown increasingly severe in recent years due to the lowered insurance reimbursement price, rising logistics cost, decrease in earning capacity of hospitals, and other factors.

------

More specifically, impacts, such as the lowered selling prices of medical instruments in general and decreases in profit margins, have become apparent due to repeated lowering of insurance reimbursement prices that are the public price of medical instruments. Also, Both Companies recognize that logistic-related costs have been growing with each passing year in the context of a labor shortage in the logistics industry in general, rising fuel costs, and other factors. In addition, business conditions of medical institutions have been growing increasingly severe, whereby, pursuant to materials for the 118th meeting of the Medical Care Subcommittee, Social Security Council of the Ministry of Health, Labour and Welfare, an operating profit margin of general hospitals in Japan, which was 1.4% in 2018, was lowered to -1.9% in 2023 under the influence of rising labor costs in medical settings, price increases, and other factors. Under such hospital business conditions, there is a growing trend among hospitals toward seeking further cost reductions in the procurement of medical materials or the like, and Both Companies recognize that a competitive environment in the wholesale industry of medical equipment has become increasingly severe.

Also, under the foregoing market environment, the strengthening of competitiveness by scaling up business operations or an industry reorganization movement aiming for the enhancement of managerial efficiency have been observed in the wholesale industry of medical equipment, whereby such industry faces increased challenges in scaling up business operations or maintaining and enhancing profitability individually, and thus an aggregation of management resources and strengthening of business foundations have become critical business challenges.

Under the aforesaid severe outside environment, OLBA HEALTHCARE has recognized for a long time as management issues of the OLBA HEALTHCARE Group an improvement of its earnings ratio, making advances into urban areas, and strengthening of its capability in negotiating purchase prices, and DVx has recognized as management issues the expansion of its business scope to fields of specialization other than cardiology, strengthening its advance into regions other than the Kanto region and strengthening of its capability in negotiating purchase price.

Based on the foregoing recognitions of the external environment and internal issues, Both Companies have, after the execution of a master agreement concerning business alliance dated October 17, 2022, executed the business alliance agreement dated March 15, 2023, and proceeded with a review towards collaboration between Both Companies. Thereafter, in the course of proceeding with a review on a system of further collaboration between Both Companies, Both Companies have, based on a judgement that they would be able to realize further enhancement of corporate value of the Groups of Both Companies through implementation of the Business Integration by establishing a relationship whereby Both Companies complement each other in their business areas and products and create a resilient management foundation capable of providing a broad range of solutions to hospitals and medical facilities, resolved at the meetings of their respective Boards of Directors to implement the Business Integration, and executed the Business Integration Agreement and the Share Exchange Agreement.

Both Companies expect the following synergies through the realization of the Business Integration.

<br> (i) Expansion of distribution chains and products in agency business; and creation of an advantage of scale

It is expected that Both Companies will be able to, through the mutually complementing business areas and products of the Groups of Both Companies, construct a solid distribution chain and realize sales growth in the agency business. More specifically, Both Companies will establish a solid nationwide distribution chain without relying on specific regions, while rolling out sales of medical instruments in general handled by the OLBA HEALTHCARE Group in the Kanto-region that is the main business area of the DVx Group, and strengthening the sale of cardiology products in the Chugoku-Shikoku region that is the main business area of the OLBA HEALTHCARE Group.

Also, it is expected that the sharing of professional expertise of Both Companies would enhance discernment concerning novel products leading to the sale of the latest medical instruments by Both Companies.

In addition, through the lowering of purchase prices and acquisition of volume-based incentives due to the strengthening of negotiation power, it is expected that Both Companies can improve the profit margin.

<br> (ii) Expansion of distribution channel and support area pertaining to in-house products; and strengthening of medical-engineering collaboration

As regards in-house developed products of the DVx Group including the "RAQUOS Injection System," "Holter ECG Analysis," and "AMI-SSS01 Series Phonocardiograph," Both Companies will promote the expansion of the market in the Chugoku-Shikoku region, that is the main business area of OLBA HEALTHCARE, and the Kingdom of Thailand, into which OLBA HEALTHCARE has been expanding, and concurrently therewith, Both Companies will endeavor to cooperate through repair and maintenance support services especially in the Chugoku-Shikoku region.

------

In addition, it is expected that the sharing of needs and expertise on the medical front amassed by Both Companies will enable Both Companies to incubate new development ideas and also enable strengthening of Both Companies' leading-edge product development capability, including alliances with start-up companies or other entities.

<br> (iii) Optimizing logistics and inventory management; and strengthening business continuity plan (BCP)

Both Companies will realize the reduction of logistics costs and optimization of supply chains through integration of logistic chains in the Chugoku-Shikoku region. More specifically, Both Companies are contemplating mutual use of the new Okayama logistic center of the OLBA HEALTHCARE Group. Also, it is expected that disposal loss will be reduced by mutually selling and providing an advance of medical instruments inventory with an expiration date held by Both Companies, leading to the improvement of the inventory turnover ratio.

In addition, Both Companies contemplate that construction of a mutually complementary structure for distribution and/or logistics chains will enable improvement to a resilient infrastructure system with a lower degree of regional dependence that is capable of stable supply of medical instruments even in times of natural disasters and/or pandemics.

<br> (iv) Facilitation of digitalization through promoting the efficiency of IT investment and leveraging data

Streamlining the business operations of Both Companies will be realized by sharing IT systems and expertise owned by Both Companies. More specifically, Both Companies contemplate facilitating utilization by Both Companies of "Li – Flo," an integrated logistics system of the OLBA HEALTHCARE Group, mutual ownership of the product master, and other measures.

Also, Both Companies contemplate that an efficient implementation of a large-scale joint investment in IT systems including a sales management system and/or logistics system will be enabled by, as the basis therefor, enhancement of financial power associated with the Business Integration.

<br> (v) Sharing professional expertise of Both Companies and strengthening cultivation of human resources through talent exchange

Both Companies contemplate that sharing know-how and expertise owned by Both Companies will enable realization of the strengthening of the cultivation of human resources of the Groups of Both Companies. More Specifically, Both Companies will proceed with implementation of trainings by specialized personnel resources and mutual utilization of educational contents. Also, Both Companies will endeavor to build up the skills of the entire organization and construct strong foundations for talented personnel by facilitating exchanges of personnel with strengths in different areas.

Both Companies contemplate that the realization of the aforementioned synergies through the Business Integration will enable Both Companies to contribute to construction of a sustainable medical supply system as the most suitable advisor for hospitals undergoing a decrease in earning capacity to improve their management, while driving a reorganization of the industry as a whole, and thereby leading to further development of the medical industry.

Also, hereafter, through the Business Integration, as regards the existing business of the OLBA HEALTHCARE Group, Both Companies aim to establish a solid position as a hybrid-type dealer of medical equipment with "comprehensiveness multiplied by specialization" by fusing together the "completeness" of the OLBA HEALTHCARE Group and "specialties" of the DVx Group; furthermore, as regards the existing business of DVx, Both Companies will realize the enhancement of corporate value of the entire Groups of Both Companies after the Business Integration through aiming for "a partner, indispensable for the medical industry, for the management of hospitals" through preparing comprehensive proposal and development skills to address the needs in medical settings centering around the two pillars of the agency business and the business of in-house products.

<br> (4) Treatment of share options and bonds with share options associated with the Share Exchange

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Grounds for the Content of Allocation pertaining to the Share Exchange and Other Particulars** 

<br> (1) Grounds and reasons for the content of allocation

Each of Both Companies, in order to ensure fairness and appropriateness upon the determination of the Share Exchange Allocation Ratio set forth in 2.(3) "Particulars of the allocation pertaining to the Share Exchange" above, appointed a third-party independent valuation institution and various advisors independent from Both Companies. OLBA HEALTHCARE appointed YAMADA Consulting Group Co., Ltd. ("**YAMADA Consulting**") as a financial advisor and an independent valuation institution, and Oh-Ebashi LPC & Partners ("**Oh-Ebashi**") as a legal advisor; and DVx appointed AGS FAS Co., Ltd. ("**AGS FAS**") as a financial advisor and an independent valuation institution, and Nishimura & Asahi (Gaikokuho Kyodo Jigyo) ("**Nishimura & Asahi**") as a legal advisor; and Both Companies commenced a comprehensive consideration.

OLBA HEALTHCARE, as set forth in (4) "Measures to ensure fairness" below, reached the conclusion that the Share Exchange Allocation Ratio is appropriate and contributes to the interests of shareholders of OLBA HEALTHCARE, after deliberation and review in a careful manner based on: the valuation report on the allocation ratio pertaining to share exchange dated May 21, 2026 obtained from YAMADA Consulting, the financial advisor and an independent valuation institution for OLBA HEALTHCARE; advice from Oh-Ebashi, the legal advisor; a result of the due diligence implemented on DVx from the beginning of February to late March 2026 and the like, and judged that implementing the Share Exchange at the Share Exchange Allocation Ratio is appropriate.

------

Meanwhile, DVx, as set forth in (4) "Measures to ensure fairness" below, engaged in the deliberation and review in a careful manner based on: the valuation report on the Share Exchange Allocation Ratio dated May 21, 2026 obtained from AGS FAS, the financial and an independent valuation institution for DVx; advice from Nishimura & Asahi, the legal advisor; a result of the due diligence implemented on OLBA HEALTHCARE from the beginning of February to late March 2026 and the like. As a result of the foregoing, DVx reached the conclusion that the Share Exchange Allocation Ratio is appropriate and contributes to the interests of its shareholders and judged that implementing the Share Exchange at the Share Exchange Allocation Ratio is appropriate.

As stated above, Both Companies have respectively reviewed the result of the due diligences implemented on each other and other factors, and repeated negotiations and discussions while referencing the result of valuations on the allocation ratio of the share exchange submitted by respective independent valuation institutions and considering comprehensively the contributory factors such as financial conditions, asset conditions, and future prospects of Both Companies. As a result, since Both Companies reached the judgement that the Share Exchange Allocation Ratio is appropriate and contributes to the interests of respective shareholders of Both Companies, judged that implementing the Share Exchange at the Share Exchange Allocation Ratio is appropriate.

The Share Exchange Allocation Ratio is subject to change upon consultation and agreement between Both Companies, in cases where a material change occurs to various conditions underpinning the valuation of the same.

<br> (2) Matters concerning valuation

<br> i) Name of the valuation institutions and relationships with Both Companies

Each of YAMADA Consulting, the independent valuation institution for OLBA HEALTHCARE, and AGS FAS, the independent valuation institution for DVx, is a valuation institution independent from Both Companies, does not constitute an affiliated party of Both Companies, and has no material interest to be stated herein concerning the Share Exchange.

With respect to the professional fee to YAMADA Consulting pertaining to the Share Exchange includes a contingency fee payable on the condition of the consummation of the Share Exchange or the like, OLBA HEALTHCARE judges that independence is not negated by the inclusion of the contingency fee payable on the condition of the consummation of the Share Exchange, taking into account the general practice in deals analogous thereto and the appropriateness of a compensation structure that would impose a considerable monetary burden in cases where the Share Exchange is not consummated. Also, whereas the professional fee to AGS FAS pertaining to the Share Exchange includes milestone fees in which multiple milestones are established in the course of the Share Exchange and fees are payable upon the achievement of the respective milestones, DVx judges that independence is not negated by the inclusion of the milestone fees, taking into account that AGS FAS considers that: paying a part of the consideration as milestone fees is desirable for AGS FAS from the viewpoint of the monetary burden on DVx instead of a solely fixed fee under the circumstances where success or failure of the Share Exchange is unclear; and it is reasonable for Both Companies.

<br> ii) Outline of the valuation

<br> (i) Valuation by YAMADA Consulting

YAMADA Consulting conducted the valuation on OLBA HEALTHCARE using the Market Price Method considering that it is listed on the Tokyo Stock Exchange Standard Market and also using the discounted cash flow method ("**DCF Method**") in order to reflect the status of its future business activities in the valuation. As regards the Market Price Method, the Reference Date is set as May 21, 2026, and it adopted the closing stock price on the Reference Date of OLBA HEALTHCARE at the Tokyo Stock Exchange Standard Market; the simple average of the closing price in the last one month from April 22, 2026 up to and including the Reference Date; the simple average of the closing price in the last three months from February 24, 2026 up to and including the Reference Date; and the simple average of the closing price in the last six months from November 25, 2025 up to and including the Reference Date. As regards the DCF Method, the valuation was conducted by discounting the future cash flow and other figures based on a financial forecast prepared by OLBA HEALTHCARE to its present value. It should be noted that the financial forecast of OLBA HEALTHCARE, on which the valuation under the DCF Method is based, includes a business year for which a substantial increase and decrease are anticipated. More specifically, in the term ending June 2027, a substantial increase in the free cash flow ("**FCF**") compared to the previous business year is anticipated due to a slowdown in the growth of working capital; in the term ending June 2028, a substantial decrease in FCF is anticipated due to a large-scale capital investment; and, in the term ending June 2029, a substantial increase in FCF is anticipated due to a decrease in the amount of the capital investment. Also, such financial forecasts are not based on the premise of the execution of the Share Exchange.

------

<br> (3) Expectation of delisting and grounds therefor

Since, as a result of the Share Exchange, DVx will become a wholly owned subsidiary of OLBA HEALTHCARE on September 1, 2026 (scheduled) that is the Effective Date, the DVx Shares are expected to be delisted on August 28, 2026 (the last trading day will be August 27, 2026).

After the delisting, while the DVx Shares will be incapable of being traded on the Tokyo Stock Exchange Standard Market, considering that the OLBA HEALTHCARE Shares to be allocated to the shareholders of DVx pursuant to the Share Exchange have been listed on the Tokyo Stock Exchange Standard Market and are capable of being traded on the financial instruments exchange market even on and after the Effective Date of the Share Exchange, Both Companies think that this will enable continuous provision of liquidity for shareholders of DVx which hold 200 or more of the DVx Shares as of the Base Time, and to whom the allocation of 100 or more shares, that is the number of shares constituting one unit of the OLBA HEALTHCARE Shares are allocated under the Share Exchange.

On the other hand, for the shareholders of DVx, which hold the DVx Shares in a number of less than 200 shares at the Base Time, the OLBA HEALTHCARE Shares will be allocated in the number of shares less than 100 shares constituting one unit of OLBA HEALTHCARE. While such fractional shares less than one unit are incapable of being sold on a financial instruments exchange market, the shareholders who will hold fractional shares less than one unit may demand OLBA HEALTHCARE to purchase the fractional shares less than one unit held thereby. For details, please refer to 2.(3) "Particulars of the allocation pertaining to the Share Exchange" (Note 3) "The treatment of fractional shares" above. Also, as regards the details of the treatment of fractions in cases where fractions less than one share are generated in accordance with the Share Exchange, please refer to 2.(3) "Particulars of the allocation pertaining to the Share Exchange (Note 4) "The treatment of fractions less than one share" above.

It should be noted that the shareholders of DVx may, up to and including August 27, 2026 that is the last trading day (scheduled), trade as usual the DVx Shares held thereby on the Tokyo Stock Exchange Standard Market, and, in addition thereto, may exercise, until the Base Time, their legitimate rights stipulated under the Companies Act and other relevant laws and ordinances.

<br> (4) Measures to ensure fairness

Considering that, upon the Share Exchange, DVx, a listed company, will become the wholly owned subsidiary of OLBA HEALTHCARE resulting from share exchange, Both Companies have implemented the following measures to ensure fairness of the Share Exchange.

<br> i) Obtaining valuation reports from independent valuation institutions

In order for Both Companies to ensure fairness in the valuation of the share exchange ratio in the Share Exchange, OLBA HEALTHCARE appointed YAMADA Consulting, a third-party valuation institution independent from Both Companies, from which it obtained the valuation report dated May 21, 2026 concerning the share exchange ratio; and DVx appointed AGS FAS, a third-party valuation institution independent from Both Companies, from which it obtained the valuation report dated May 21, 2026 concerning the share exchange ratio. For the outlines of the respective valuation reports, please refer to (2) "Matters concerning valuation" above. Neither of Both Companies has obtained a written opinion (*i.e.*, a fairness opinion) from the respective independent institutions to the effect that the share exchange ratio in the Share Exchange is fair for the shareholders of Both Companies from a financial perspective.

<br> ii) Advice from independent law firm(s)

As a legal adviser for the Share Exchange, OLBA HEALTHCARE appointed Oh-Ebashi and DVx appointed Nishimura & Asahi respectively, and each party has obtained advice from a legal point of view concerning various formalities as well as the methods and procedures of the Share Exchange. Both Oh-Ebashi and Nishimura & Asahi are independent from Both Companies and do not have a material interest in Both Companies in relation to the Business Integration including the Share Exchange.

------

Although Oh-Ebashi has entered into a legal advisory agreement with OLBA HEALTHCARE, Oh-Ebashi is an outside law firm providing legal services not only to OLBA HEALTHCARE but to a large number of clients, and OLBA HEALTHCARE has entered into the legal advisory agreement therewith seeking legal consultancy as one of those clients of Oh-Ebashi from time to time based on the firm's practice areas and specialty; as such, the firm's independence is not harmed by the fact that such agreement has been entered into. Considering also that the professional fee for Oh-Ebashi is calculated based on their operating hours multiplied by an hourly price and does not include any contingency fee payable on the condition that the transaction is consummated, OLBA HEALTHCARE has judged that there is no problem in the independence of the firm.

As there is no capital ties and personal relationships between Both Companies as of today, and neither of Both Companies constitutes an affiliated party, no conflict of interest will arise for Both Companies upon decision making at the meeting of the Board of Directors concerning the Share Exchange, hence, no specific measures are taken other than those stated in i) "Obtaining valuation reports from independent valuation institution" and ii) "Advice from independent law firms" above.
