Overview

We are one of the leading holistic health services providers in Japan. Medirom is a franchiser and operator of healthcare salons across Japan and is a preferred platform partner for large consumer brands, healthcare service providers, and government entities to affect positive health outcomes. Through our well-known retail salon brands, including primarily Re.Ra.Ku®, nascent tech platforms, and targeted health consulting and marketing, we have formed a “healthtech” segment.

We are a joint-stock corporation incorporated in Japan under the Companies Act. Our Company was originally incorporated in Japan in 2000. In 2018, we established three wholly-owned subsidiaries, Bell Epoc Wellness Inc. (“BEW”), JOYHANDS WELLNESS Inc., and Medirom Human Resources Inc. (“MHR”), and acquired our fourth wholly-owned subsidiary, Decollte Wellness Corporation (“DW”). In December 2020, ADSs representing our common shares were listed on The Nasdaq Capital Market. In May 2021, we acquired our fifth wholly-owned subsidiary, SAWAN Co. Ltd (“SAWAN”). In July 2021, in order to speed up the decision-making process, improve business efficiency, and maximize business value, we reorganized and re-designated certain of our then wholly-owned subsidiaries by business functions. As part of the reorganization, DW merged with and into BEW with BEW being the surviving entity. As a result of the merger between DW and BEW, BEW (currently known as Wing Inc.) now operates the salons previously owned by DW. Since July 1, 2021, Wing Inc. has been managing the business operations of the majority of our relaxation salons, excluding those located in spa facilities or under “Ruam Ruam” brand. In addition, we established Bell Epoc Power Partners Inc. (“BJP”), which succeeded to the rights and obligations relating to the salon management entrusted division previously operated by BEW. In October 2021, we acquired 60% of the ownership interest in ZACC Kabushiki Kaisha (“ZACC”), a high-end hair salon company, and acquired the remaining 40% of the ownership interest in ZACC in January 2022.

On May 31, 2023, our board of directors approved a second reorganization (the “Second Reorganization”), which consists of (i) an Incorporation-type Company Split Plan, pursuant to which our Company spun off the Digital Preventative Healthcare business and transfer and assign it to MEDIROM MOTHER Labs Inc., a newly established wholly-owned subsidiary, which is expected to solely conduct the Digital Preventative Healthcare business going forward; and (ii) an Absorption-type Company Split Agreement, pursuant to which our Company spun off the existing salon development department (which is responsible for sourcing and setting up store spaces) and general corporate department (which includes accounting, legal, general affairs, human resources, IT and any other corporate functions) and had Bell & Joy Power Partners Inc., an existing wholly-owned subsidiary, assume such operations going forward (on the same day, Bell & Joy Power Partners Inc. was renamed into MEDIROM Shared Services Inc.). The Second Reorganization became effective on July 3, 2023.

The Company implemented an organizational restructuring through a business combination of its wholly-owned subsidiaries, effective January 1, 2025. Wing Inc. succeeded in all rights and obligations of Medirom Human Resources Inc. through an absorption-type merger. It succeeded in all rights and obligations held by JOYHANDS WELLNESS Inc. regarding its hot spring spa business operations through an absorption-type demerger. Furthermore, effective on the same date, it changed its name from Wing Inc. to MEDIROM Wellness Co. This organizational restructuring is a transaction under common control and has no impact on the condensed consolidated financial statements.

Separately, on January 1, 2025, the Company entered into a share transfer agreement with a third party and sold all of its shares of its wholly owned subsidiary, JOYHANDS WELLNESS Inc. As a result of the share transfer, the Company deconsolidated JOYHANDS WELLNESS Inc. as of January 1, 2025.

As of December 31, 2023, the Company had entered into six share transfer agreements, pursuant to which we have agreed to sell and transfer an aggregate of 1,781 shares in MML, or approximately 3.56% of its total shares outstanding, to certain third-party investors. The purpose of our 2023 reorganization and the transfer of MML shares was to make quicker decisions and seek external equity financing of MML as a spun-off startup to accelerate its growth. Since then, MML began to finance from its own equity financing. However, we intend to maintain our status as the controlling shareholder of MML.

On June 30, 2024, we signed an agreement to acquire 70% of the issued and outstanding equity of Japan Gene Medicine Corporation and make it a subsidiary of the Company. See “—Planned Acquisition of Japan Gene Medicine Corporation.”

As of June 30, 2025, we had the following subsidiaries: MEDIROM Wellness Co., MEDIROM Shared Services Inc., SAWAN CO., LTD, ZACC Kabushiki Kaisha, MEDIROM MOTHER Labs Inc., and MEDIROM Rehab Solutions Inc. The chart below illustrates our corporate structure as of June 30, 2025.

Our principal operating subsidiaries as of June 30, 2025 are as follows:

​

Our principal business is to own, develop, operate, manage, and support relaxation salons through the franchising and direct ownership of such salons throughout Japan. We seek to be the leading provider of relaxation and bodywork services in the markets we serve and to become the most recognized brand in our industry through the steady and focused expansion of relaxation salons in key markets throughout Japan and potentially abroad.

We operate three synergistic lines of businesses: (1) Relaxation Salon Segment (retail); (2) Luxury Beauty Segment (retail); and (3) Digital Preventative Healthcare Segment (healthtech). By combining brand strength and core retail competencies, including a broad physical footprint in population dense areas across the country, with proprietary technologies and partnerships, our business provides unique, value-added healthcare services to our customers with scale, customization, and cross-network effects that we believe few other companies in the industry can emulate.

As of June 30, 2025, the Relaxation Salon Segment had 304 locations across Japan, located within the country’s major cities. The Relaxation Salon Segment is our core business and accounted for ¥2,902,972 thousand (US$20,136 thousand), or 89.5% of our total revenue for the six months ended June 30, 2025, and ¥3,138,956 thousand (US$21,773thousand), or 90.3% for the same period of 2024.

The Luxury Beauty Segment operates high brand beauty salons in the central areas of Tokyo. The Luxury Beauty Segment accounted for ¥268,445 thousand (US$1,862 thousand), or 8.3% of our total revenue for the six months ended June 30, 2025, and ¥292,631thousand (US$2,030 thousand), or 8.4% of our total revenue for the same period of 2024.

The Digital Preventative Healthcare Segment accounted for ¥71,954 thousand (US$499 thousand), or 2.2% of our total revenue for the six months ended June 30, 2025, and ¥43,694 thousand (US$303 thousand), or 1.3% for the same period of 2024.

Key Financial Definitions and Non-U.S. GAAP Measures

Revenue.  Revenue consists of the following items: revenue from directly-operated salons, franchise revenue, and other revenues.

4

Table of Contents

Cost of Revenue.  The total cost of delivering services to customers consists of the following items: cost of goods sold, subcontract expenses, cost of franchise royalty and affiliation revenue, salon operating cost, salaries for therapists, legal and welfare expenses, provision for paid annual leave, travelling expenses, salon rent, depreciation and amortization, gain/loss from asset retirement obligation, interest expenses for asset retirement obligation, business consignment expenses, and others.

Selling, General and Administrative Expenses.  Selling, general and administrative expenses, or SG&A, includes the costs to sell and deliver services and the costs to manage the company as follows: directors’ compensations, salaries and allowances, bonuses, legal welfare expenses, provision for paid annual leave, recruiting expenses, travel expenses, advertising expenses, rent, taxes and duties, commission fees, compensations, depreciation and amortization, provision for doubtful accounts, and others.

Impairment Loss on Long-lived Assets. Long-lived assets include property and equipment, right-of-use lease assets, internal use software, and definite-lived intangible assets. The Company reviews the carrying value of long-lived assets for impairment whenever events or circumstances occur that indicate that the carrying value of the assets may not be recoverable. If the assets are not deemed to be recoverable, an impairment is recorded if the fair value of the asset grouping is less than the carrying value.

Non-U.S. GAAP Measures

Adjusted EBITDA.  We define Adjusted EBITDA as net income (loss), adjusted to exclude: (i) dividend and interest income, (ii) interest expense, (iii) gain from bargain purchases, (iv) other, net, (v) income tax expense, (vi) depreciation and amortization, (vii) losses on sales of directly-owned salons to franchisees, (viii) gains (losses) on disposal of property and equipment, and other intangible assets, (ix) impairment loss on long-lived assets and (x) stock-based compensation expense. Management considers Adjusted EBITDA to be a measurement of performance which provides useful information to both management and investors. Adjusted EBITDA should not be considered an alternative to net income or other measurements under GAAP. Adjusted EBITDA is not calculated identically by all companies and, therefore, our measurements of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.

We use Adjusted EBITDA to enhance our understanding of our operating performance, which represents our views concerning our performance in the ordinary, ongoing and customary course of our operations. We historically have found it helpful, and believe that investors have found it helpful, to consider an operating measure that excludes certain expenses relating to transactions not reflective of our core operations. Stock-based compensation expense represents non-cash charges related to equity awards granted by us. Prior to 2021, we did not recognize any stock-based compensation expense. Our management believes the measurement of these amounts can vary considerably from period to period and depend substantially on factors that are not direct consequences of the performance of our Company and are not within our management’s control. Therefore, our management believes that excluding these expenses facilitates comparisons of our operational results and financial performances in different periods, as well as comparisons against similarly determined non-GAAP financial measures of comparable companies.

The information about our operating performance provided by this financial measure is used by our management for a variety of purposes. We regularly communicate Adjusted EBITDA results to our board of directors, and we discuss with the board our interpretation of such results. We also compare our Adjusted EBITDA performance against internal targets as a key factor in evaluating our periodic operating performance at each salon level, segment level, and consolidated level, largely because we believe that this measure is indicative of how the fundamental business is performing and is being managed.

Adjusted EBITDA Margin.  Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA for a period by total revenue for the same period.

Half-year Progress of Key Performance Indicators

In assessing the performance of our relaxation business, we consider several key performance indicators used by management. We receive monthly performance reports from our system and our relaxation salons which include key performance indicators per salon including sales, number of customers, number of newly-acquired customers, number of repeat customers, sales per customer, and operation ratio. We believe these indicators provide us with useful data with which to measure our performance and to measure the performance of our own and our franchisees’ relaxation salons.

These key indicators include:

Factors Impacting our Operating Results

We expect that our results of operations will be affected by a number of factors and will primarily depend on the global economy, general market conditions, customer preference, and the competitive environment.

Our revenues, operating results and financial performance are impacted by a multitude of factors, including, but not limited to:

Business Environment.  According to the 2022 Yano Report, which is still the latest edition of the report, the relaxation market continues to see industry consolidation and notable category entrants from athletic and personal training services, and body stretching. We believe that market share will be further transferred to the category leaders in the industry, as smaller, private operators sell their businesses for retirement and/or market competition reasons, which industry trends, as we believe, may benefit us if realized.

Table of Contents

Cost of Services.  The cost of service of relaxation business has been increasing. In our relaxation business, a substantial majority of our personnel are paid wages at or close to the statutory minimum wage. For the past decade, such minimum wage has been continuously increasing throughout Japan. In 2012, the minimum wage in Tokyo was JPY850 (US$5.90), but had risen to JPY1,072 (US$7.44) as of December 31, 2022, according to the Ministry of Health, Labor and Welfare. The trend continued in 2023 and in 2024. The minimum wage in Tokyo increased annually by 3.8% to JPY1,113 (US$7.72) as of December 31, 2023, and by 4.5% to JPY1,163 (US$8.07) as of December 31, 2024. From October 2025, the minimum wage in Tokyo was raised by 5.4% to JPY1,226 (US$8.50). We believe this trend will continue and may affect our operating results significantly.

In addition, we are facing inflationary trends in general prices, including utility costs, due to factors such as geo-political developments and the recovery of the Japanese economy. We updated our service prices in May 2023 as part of a renewal of our primary service lines in order to deal with such increased costs, as well as to adjust to the long-term trend of minimum wage increases. We may also consider further updates to our service prices to reflect such increases in our costs in the future.

Update of Business Model.  Since the fourth quarter of 2021, we have sought to become more asset-light by selling our owned salons to third-party investors and continuing to operate these sold salons on behalf of the investors. We believe this model will maximize the return on capital investment in our relaxation salon segment and allow us to accelerate salon openings by reinvesting the proceeds from the sales of salons, improve operational efficiency by focusing on salon operations, and generate additional income from the salons that were sold to investors and are under our management. In the first six months of 2025, we sold 11 salons, resulting in 56 salons owned by investors and under our management as of June 30, 2025.

Specific Health Guidance Program.  In our Digital Preventative Healthcare Segment, we have been continuously involved in the Specific Health Guidance Program, promoted by the Ministry of Health, Labor and Welfare of Japan, which utilizes our upgraded Lav® application. We had active subscription orders from 101 corporate insurance associations as of June 30, 2025, an increase from 97 as of December 31, 2024. The number of users under the Specific Health Guidance Program was 1,835 for the six months ended June 30, 2025, a significant increase from 946 in the same period in 2024. In addition, during the six months ended June 30, 2025, we focused more on providing similar services to young employees at large corporations who are not eligible for the Specific Health Guidance Program. The number of younger generation users, which we define as users below the age of forty, who participated in the program for younger generations was 555 in the six months period ended June 30, 2025, as compared to 311 in the same period in 2024.

Planned Acquisition of JGMC

On June 30, 2024, we entered into a share transfer agreement for the purpose of acquiring 70% of the issued and outstanding common shares of Japan Gene Medicine Corporation (“JGMC”) for ¥2,000,000 thousand (the “Initial Acquisition Purchase Price”) and making JGMC our subsidiary (the “Initial Acquisition”). In addition, we concurrently entered into a binding memorandum of understanding (the “MOU”) under which we were granted an option to purchase the remaining 30% of the issued and outstanding shares of JGMC that we will not acquire as part of the Initial Acquisition (the “Remaining Shares”). As of the date of this interim financial report, we are in negotiations with multiple banks and financial institutions to finance our planned acquisition of 70% of the equity of JGMC. However, as of the date of this annual report, we have not determined how much cash on hand, if any, will be used for this purpose. In addition, the amount and terms of the financing are subject to change, and we may seek additional acquisition financing arrangements going forward. We expect the incurrence of this additional indebtedness to significantly increase our interest costs in future periods.

We expect to record a significant amount of goodwill in connection with the Initial Acquisition, reflecting the sum by which the aggregate fair value of consideration for the Initial Acquisition exceeds the estimated fair value of the identifiable assets acquired and liabilities assumed as of the acquisition date. Such goodwill will be subject to impairment testing. If circumstances arise indicating that goodwill recorded in connection with the acquisition may be impaired, such as if we are unable to successfully realize the expected benefits of the acquisition, we may be required to record an impairment loss up to the full value of such goodwill on our consolidated balance sheet.

We also expect to record a certain amount of intangible assets and other assets of JGMC in connection with the Initial Acquisition, which we plan to reflect on our balance sheet after completion of the purchase price allocation, which shall be subject to the same impairment testing as the aforementioned goodwill.

​

Revenues

Revenues derived from our Relaxation Salon Segment were JPY2,902,972 thousand (US$20,136 thousand) in the six months ended June 30, 2025 and JPY3,138,956 thousand (US$21,773 thousand) in the six months ended June 30, 2024.

Table of Contents

The revenue from our Relaxation Salon Segment consists of revenue from directly-operated salons, revenue from franchising, and other revenues. In the six months ended June 30, 2025, our revenue from directly-operated salons increased to JPY2,459,319 thousand (US$17,058 thousand) from JPY2,053,537 thousand (US$14,244 thousand) in the same period in 2024. Our revenue from franchising decreased to JPY322,580 thousand (US$2,237 thousand) from JPY415,724 thousand (US$2,884 thousand) in the same period in 2024.

The primary factor for the decrease in revenues from directly-operated salons between the first six months in 2024 and 2025 was decreased sales of salons under the sale-and-outsource business model, which generated JPY669,695 thousand (US$4,645 thousand) in the six months ended June 30, 2024, compared to JPY121,073 thousand (US$840 thousand) in the same period in 2025. On the other hand, store operation outsourcing revenue subsequent to the sales of salons also increased from JPY598,297 thousand (US$4,150 thousand) in the six months ended June 30, 2024 to JPY772,913 thousand (US$5,361 thousand) in 2025.

The primary reason for the decrease in revenues from franchising was a decrease in the number of franchised salons. As of June 30, 2025, the number of franchised salons decreased to 81 compared to 93 salons as of June 30, 2024, due to our acquisitions of franchised salons and franchisees’ withdrawal from the business.

Our initial franchise fees and expected renewal franchise fees are recognized as revenue ratably over the expected average franchising contract life (seven to 10 years) on the opening date of the new franchised salons. In addition, our revenue from franchise royalties includes revenues from recurring royalty income, rental income from subleased salon properties, construction of franchised salons, uniforms and training sales.

Revenue from our Digital Preventative Healthcare Segment increased from JPY43,694 thousand (US$303 thousand) in the six months ended June 30, 2024 to JPY71,954 thousand (US$499 thousand) in the same period in 2025. This increase was primarily due to an increase in the number of participants in the Health Guidance Program and other Lav® app services.

Revenue from our Luxury Beauty Segment was JPY268,445 thousand (US$1,862 thousand) in the six months ended June 30, 2025, a decrease from JPY292,631 thousand (US$2,030 thousand) in the same period in 2024. The primary reason for the decrease was the sale of one of ZACC’s salons in December 2024, which was repurchased in April 2025, and thus contributed only two months of revenues.

As a result of the foregoing, our total revenues were JPY3,243,371 thousand (US$22,497 thousand) in the six months ended June 30, 2025 as compared to JPY3,475,281 thousand (US$24,105 thousand) in the six months ended June 30, 2024.

Cost of Revenues

For the six months ended June 30, 2025 and 2024, the cost of revenues was JPY2,891,963 thousand (US$20,060 thousand) and JPY2,898,717 thousand (US$20,106 thousand), respectively. The slight decrease was primarily due to an decrease in sales of salons, a decrease in costs related to revenues from franchising due to decreased number of franchised salons, offset by an increase in payroll and outsourcing fees for our employed or contracted therapists, and cost recognition of rehabilitation business which was acquired and began to be consolidated in October 2024. The cost of revenues as a percentage of total revenues was 89.2% during the six months ended June 30, 2025 compared with 83.4% during same period in 2024.

Selling, General and Administrative Expenses

For the six months ended June 30, 2025 and 2024, the selling, general and administrative expenses were JPY1,189,604 thousand (US$8,251 thousand) and JPY1,213,238 thousand (US$8,415 thousand), respectively. Selling, general and administrative expenses as a percentage of total revenues in the six months ended June 30, 2025 and 2024 were 36.7% and 34.9%, respectively. The decrease in selling, general and administrative expenses in the first six months in 2025 compared to the same period in 2024 was primarily due to a decrease in training expenses, reversal of allowance for doubtful accounts, decrease in the professional fees for acquisition activities, partially offset with an increase in directors’ salaries, and increase in amortization of store operating rights for the increased number of reacquired salons from investors.

Impairment Loss on Long-lived Assets

We recognized an impairment loss on long-lived assets of JPY 84,589 thousand (US$587 thousand) for the six months ended June 30, 2025, while we did not recognize impairment loss on long-lived assets for the six months ended June 30, 2024.

Interest Expense

Interest expense increased from JPY20,631 thousand (US$143 thousand) in the six months ended June 30, 2024 to JPY26,011 thousand (US$180 thousand) in the six months ended June 30, 2025, primarily due to an increase in the amount of borrowings.

Gain from Sales of Salons

We recognized gain from sales of salons of JPY155,365 thousand (US$1,078 thousand) in the six months ended June 30, 2025, for the sales of salons to the investors from whom we also purchased back previously sold salons and settled the sales and purchase-back transactions without cash payments, compared to JPY31,793 thousand (US$221 thousand) for the same type of transactions in the six months ended June 30, 2024.

Other Income—Net

Total other income increased by JPY61,803 thousand (US$429 thousand) to JPY102,541 thousand (US$711 thousand) in the six months ended June 30, 2025 from JPY40,738 thousand (US$283 thousand) in the six months ended June 30, 2024. The increase was primarily due to an increase in the subsidies we received.

Income Tax Expense

Income tax expense for the six months ended June 30, 2025 was JPY130 thousand (US$1 thousand), compared to JPY3,605 thousand (US$25 thousand) in the six months ended June 30, 2024.

Net Loss and Adjusted EBITDA

Our consolidated net loss for the six months ended June 30, 2025 was JPY (690,471) thousand (US$(4,789) thousand), or (21.3) % of our consolidated revenue, while our consolidated net loss for the six months ended June 30, 2024 was JPY (582,181) thousand (US$(4,038) thousand), or (16.8) % of our consolidated revenue, as a result of the key factors described above. Our Adjusted EBITDA decreased to JPY(430,939) thousand (US$(2,989) thousand) in the six months ended June 30, 2025 from JPY (404,112) thousand (US$(2,803) thousand) in the six months ended June 30, 2024, resulting in a decline in Adjusted EBITDA margin to (13.3) % for the six months ended June 30, 2025 from (11.6) % for the six months ended June 30, 2024.

B.Liquidity and Capital Resources

Liquidity is a measure of our ability to meet potential cash requirements. As of June 30, 2025, we had cash and cash equivalents of JPY32,663 thousand (US$227 thousand). We have generally funded our operations with cash flow from operations and sales of relaxation salons, and, when needed, with borrowings from Japanese financial institutions and other debt or equity financings. Our principal uses for liquidity have been to fund development of new salons, acquisitions of salons or relaxation businesses from franchisees or third parties, our daily operations, and general working capital purposes.

Going Concern

The Company had a working capital deficit as of June 30, 2025 and for the last three years and an accumulated deficit as of June 30, 2025. Despite having a positive shareholders’ equity of ¥298,011 thousand (US$2,067 thousand) as of June 30, 2025, the Company had net loss position and negative cash flows from operations for the six months ended June 30, 2025. We expect that our cash and cash equivalents as of June 30, 2025 of ¥32,663 thousand (US$227 thousand) may not be sufficient to fund our operating expenses, capital expenditure requirements, and debt service obligations for the 12 months following the date of the condensed consolidated financial statements. These conditions, among others, raise substantial doubt about the ability of the Company to continue as a going concern. The continuation as a going concern is dependent upon the Company’s ability to meet its financial requirements, raise additional capital, and the success of its future operations.

Management plans to alleviate the conditions that raise substantial doubt by raising additional capital through the issuance of common stock, other equity or debt financings, or refinancing of existing debt obligations. In addition, the Company has implemented plans to reduce the operating, and overhead and administrative expenses, including but not limited to cutting discretionary spending, renegotiating contracts to lower service costs, and switching to less expensive suppliers. However, the Company’s ability to issue equity securities or obtain debt financing on acceptable terms, or at all, will depend on, among other things, its financial performance, general economic factors, including inflation and then-current interest rates, the condition of the credit and capital markets and other events, some of which may be beyond the Company’s control.

Cash Flows

The following table sets forth a summary of our cash flows for the periods indicated.

​

Operating Activities

Net cash flows used in operating activities improved from a usage of JPY785,720 thousand (US$5,450 thousand) in the six months ended June 30, 2024 to a usage of JPY351,912 thousand (US$2,441 thousand) during the six months ended June 30, 2025, primarily due to an increased depreciation and amortization expenses in the six months ended June 30, 2025, compared with the one in the same period in 2024, along with a decrease in balance of accounts receivable-other, an increase in balance of accounts payable, and increase in balance of other current liabilities from those as of December 31, 2024, partially offset with a decrease in gain from sales of directly-owned salons in the six months ended June 30, 2025, compared with the one in the same period in 2024, and an increase in balance of prepaid expenses and other current assets, and a decrease in accounts payable from those as of December 31 2024.

As of June 30, 2025, we have 13 business loans outstanding from four Japanese financial institutions. The balance on the outstanding loans as of June 30, 2025 was JPY1,110,365 thousand (US$7,702 thousand) with interest rates ranging from 0.20% to 2.00%, and a weighted average interest rate of 1.20%.

Convertible Bonds

As of June 30, 2025, we had JPY800,000 thousand (US$5,549 thousand) aggregate principal amount of convertible bonds outstanding, consisting of convertible bonds that we issued to Kufu Company Inc., a Japanese company, in December 2022 and to Triple One Investment Limited Partnership, a Japanese limited liability investment partnership, in October 2024.

The Kufu Company bonds, which we issued to Kufu Company in JPY500,000 thousand (US$3,468 thousand) aggregate principal amount, are unsecured, accrue interest at a rate of 5.0% per annum, payable on June 30, 2023 and semi-annually thereafter, and will mature on December 31, 2025, unless earlier converted. At any time between the six-month anniversary date of December 28, 2022 and before the close of business on December 30, 2025, Kufu Company, as the bond holder, may convert the bonds at its option, in whole or in part, into our common shares by exercising stock options that were issued to Kufu Company in connection with the bonds. The exercise price for the stock options is JPY755 per common share. This price is subject to reasonable adjustment under certain circumstances, including the Company’s issuance of shares at a price lower than the exercise price, but Kufu Company has waived any right to an adjustment in connection with the Company’s capital-raising transactions occurring prior to the maturity date. A downward adjustment to the exercise price would result in more shares being issued to Kufu Company upon conversion of the convertible bonds. On November 1, 2024, Kufu Company signed an agreement to amend certain terms of the convertible bonds.

Under the terms of the amendment, Kufu Company agreed to (i) waive its redemption right (ii) revise the maturity date from December 28, 2027 to December 31, 2025 and (iii) revise the deadline for exercising its conversion right from December 27, 2027 to December 30, 2025. Upon maturity, we currently plan to repay the convertible bonds held by Kufu Company through proceeds from one or more debt financings and/or issuances of convertible debt instruments, although the sources of such funds are subject to change.

In October 2024, we issued corporate convertible bonds in the aggregate principal amount of JPY300,000 thousand (US$2,081 thousand) to Triple One Investment Limited Partnership, a Japanese limited liability investment partnership. The bonds are unsecured, accrue interest at a rate of 2.0% per annum, payable on June 30, 2025 and semi-annually thereafter, and will mature on October 29, 2027. At any time between October 25, 2024 and October 29, 2027, Triple One may convert each bond, which are issued in denominations of ¥100,000 thousand and may be converted in whole but not in part, into our common shares at a conversion price of JPY 957 per share by exercising stock options that were issued to Triple One in connection with the bonds. In addition, there are certain conditions under the bond indenture, such as our failure to timely pay interest and remedy the nonpayment within a cure period, upon the occurrence of which Triple One is entitled to demand immediate repayment of the bonds.

Corporate Bonds

On June 16, 2024, we issued corporate bonds in aggregate principal amount of JPY70,000 thousand (US$485 thousand) and which mature on May 30, 2025 to Tan Lee, an individual. The maturity date was updated to October 31, 2025. As of June 30, 2025, the outstanding balance of such corporate bonds was JPY30,000 thousand (US$208 thousand).
