This report presents an overview of our business performance and key performance indicators (KPIs) for the first quarter of 2026 (January–March 2026). It also highlights trends over the past five quarters (2025Q1–2026Q1) to provide investors with a broader perspective. Data includes salons with comparable financial and customer metrics.

1. Salon Operation Business

In 2026Q1, our salon business recorded an Average Revenue Per Customer of 7,822 JPY (+7.7% YoY), exceeding the Japanese industry average of 4,806 JPY by approximately 3,016 JPY.(*1) This performance reflects the strength of our service offering, supported by our training infrastructure and an educational curriculum refined over 25 years.

Strategy Update: Hybrid Staffing Model

In addition, to support sustainable growth in our store operations and further enhance service quality, we have been strategically upgrading the working styles of our store staff (therapists) since 2025. In addition to traditional employment models centered on hourly wages and fixed salaries, we have been promoting the adoption and expansion of a professional contractor (independent contractor) model.

*(2) Number of Salons: Total number of directly operated and franchise salons at the end of each quarter.

*(3) Total Customers: Number of customers visiting the salons.

*(4) Revenue Per Customer: Average revenue calculated by dividing total sales by the number of customers.

*(5) Repeat Ratio: Ratio of repeat customers to total customers.

*(6) Operating Ratio: Ratio of treatment time to total working hours of therapists (excluding break times).

The average number of stores included in the data aggregation for each quarter was 284 in 25Q1, 281 in 25Q2, 276 in 25Q3, 273 in 25Q4, and 268 in 26Q1.

As a result of advancing both the transition to contractor agreements and the hiring of independent contractors, the proportion of independent contractors among therapists reached 45.1% as of Q1 2026, an increase from 29.8% in the same period of the previous year (*7).

(*7) The number of therapists includes employees and independent contractors who worked as of the end of March 2025 and March 2026, respectively, at MEDIROM Wellness Co., Ltd. and SAWAN Co., Ltd.

Furthermore, to support sustainable growth in our salon business and enhance service quality, we have been implementing a strategic update to our staffing model since 2025. In addition to the conventional employment model based on hourly and fixed wages, we have been expanding the use of professional contractor (independent contractor) arrangements. As a result, independent contractors accounted for 53% of our total workforce as of the end of the first quarter.

This model introduces a performance-based compensation structure without fixed salary caps, allowing therapists to better align their earnings with their efforts. We believe this approach supports higher motivation and contributes to improved retention. Through this hybrid staffing structure, we aim to build a foundation that enables diverse talent to thrive over the long term while maintaining stable KPI performance.

Looking ahead, we plan to continue to optimize this hybrid staffing model to further enhance therapist earnings. At the same time, we aim to strengthen our high-value, high-margin business model and enhance our corporate value over the medium to long term.

2. World ID

World ID is a global digital identity protocol developed by Tools for Humanity, co-founded by Sam Altman and Alex Blania, to provide “Proof of Personhood” in the age of AI.

In February 2026, we commenced a strategic partnership with Tools for Humanity under a Master Service Agreement. As part of this initiative, we have continued to deploy Orb devices primarily at Re.Ra.Ku® locations, resulting in approximately 31,000 total verifications as of the end of 2026Q1.

MEDIROM Healthcare Technologies Inc. (NASDAQ: MRM)

The decrease in authentication numbers during the first quarter was mainly due to the January–March period being a seasonal slow period, combined with a lower number of business operating days.

3. HealthTech Business (Lav®)

MEDIROM Healthcare Technologies Inc. (NASDAQ: MRM)

Our HealthTech division offers “Lav®,” a fully remote Specified Health Guidance service delivered through web-based interviews and app-based chat functions.

Therapists from our Re.Ra.Ku® salons also serve as Lav® coaches, creating operational synergies across our businesses. This structure reduces the need for external recruitment and provides additional income opportunities for therapists, contributing to a high-margin business model.

As of 2026Q1, we serve 106 health insurance providers, with cumulative users reaching 13,226.

A next-generation healthcare matching service

that connects health challenges with suitable health professionals.
Through the chat feature of our proprietary app, Lav, our dedicated coaches will help you improve your lifestyle habits.

It's easy to keep track of things with the app! Get chat support from a coach! Choose your favorite coach!
Just snap a photo of your meals;

Specified Health Guidance is a support program designed to prevent lifestyle-related diseases associated with factors such as unbalanced diet, lack of sleep, insufficient exercise, smoking, and stress.

Based on the results of “Specified Health Checkups”—health examinations focused on metabolic syndrome for individuals aged 40 to 74—specialized staff, including public health nurses and registered dietitians, provide guidance to help high-risk individuals review and improve their lifestyle habits. Since April 2008, medical insurers, including National Health Insurance and employee health insurance providers, have been required to implement both “Specified Health Checkups” and “Specified Health Guidance.”

The Ministry of Health, Labour and Welfare has set national targets of at least 70% for health checkup participation and 45% for health guidance participation among eligible individuals. However, actual rates for fiscal year 2021 were 56.5% and 24.6%, respectively, indicating significant room for future market expansion.

The adoption of ICT in Specified Health Guidance has been increasing steadily, and in recent years—partly driven by the COVID-19 pandemic—the adoption rate has exceeded 50% (according to the Japan Health Guidance Association).

We have been operating in the Specified Health Guidance business within the ICT sector since fiscal year 2019. As of the end of March 2026, we have established partnerships with 106 insurers, and the cumulative number of users has surpassed 13,000, reaching a total of 13,226.

Furthermore, we are expanding our business to meet the diversifying needs of health insurance associations by seeking to grow our new contracts for voluntary lifestyle improvement programs. These programs target younger individuals under the age of 40, extending beyond the standard age range for Specified Health Guidance (40 and older).

The coaches responsible for Lav® program guidance are primarily comprised of active therapists from our salon business (Re.Ra.Ku® Group). By establishing a system where existing group staff can participate as

MEDIROM Healthcare Technologies Inc. (NASDAQ: MRM)

coaches, we reduce new recruitment costs for coaches and can further our efforts to achieve a profitability model. Consequently, therapists who serve as coaches receive higher compensation, which effectively boosts their overall income.

Since this coaching role is exclusively available to therapists currently working at Re.Ra.Ku®, the model encourages long-term retention, particularly among high-earning therapists. Our core Re.Ra.Ku® business and the Lav® business create close internal synergies, and this overall business model structure serves as one of our key competitive advantages.
