To all directors and clinic presidents considering the sale of an ENT clinic, and to those considering the acquisition of medical institutions. ENT clinics are characterized by their susceptibility to seasonal illnesses such as influenza and hay fever, making specialized perspectives essential for M&A valuation and strategy. This article provides a multi-faceted explanation covering key valuation points for ENT clinic M&A, management challenges unique to seasonally fluctuating specialties, the impact of medical corporation structures, medical fee revisions, taxation, and relevance to regional medical care planning. We offer practical information to guide your clinic’s business succession to success.

Characteristics and Valuation Points of ENT Clinic M&A

To successfully conduct M&A for an ENT clinic, it is crucial to deeply understand the unique characteristics of this specialty and perform an appropriate valuation. ENT clinics handle a wide range of needs, including acute conditions like acute otitis media, sinusitis, and pharyngitis, as well as chronic conditions such as allergic rhinitis, tonsil hypertrophy, sleep apnea syndrome, and dizziness. They also offer services like hearing aid consultations and rehabilitation for swallowing disorders. This diversity can complicate revenue valuation in M&A.

Valuation items in M&A are diverse, but the following points are particularly emphasized:

• Profitability and Financial Status: Trends in sales, profit margins, and cash flow over the past few years. Stability throughout the year, considering the impact of seasonal fluctuations, is evaluated.
• Location and Regional Characteristics: Accessibility from the station, parking availability, surrounding competition, and demographics. Especially if there are many pediatric patients, ease of access from residential areas and the presence of nearby nursery schools, kindergartens, and elementary schools can be evaluation factors.
• Facilities and Equipment: The completeness and age of specialized equipment such as electronic health record systems, fiber scopes, CT scanners, and audiology booths. The necessity of post-acquisition capital investment affects the valuation.
• Physician and Staff Structure: Physician specialization, balance of full-time and part-time staff, skill levels of nurses and medical administrative staff, and retention rates. These are essential for smooth post-acquisition operations.
• Regional Collaboration: Collaboration status with surrounding hospitals and other clinics, and records of referrals and reciprocal referrals. The significance of the clinic’s role in regional healthcare is a major attraction for buyers.
• Diversity of Services: The presence of specialized clinics that can expect stable year-round patient flow, such as those for allergy treatment, hearing aids, and sleep disorders, in addition to acute conditions, enhances valuation.

By comprehensively evaluating these elements, it becomes possible to determine the appropriate sale price for your clinic. Collaborating with experts and conducting detailed due diligence will be key to a successful M&A.

Management Challenges Unique to Seasonally Fluctuating Specialties and M&A Strategies

ENT clinics are strongly influenced by seasonal illnesses like influenza, colds, and hay fever, leading to significant fluctuations in year-round patient numbers and revenue. These seasonal variations present unique challenges in management planning and cash flow, and are important considerations in M&A valuation.

For example, patient numbers tend to increase significantly during the winter infectious disease season and the spring hay fever season, leading to a temporary rise in revenue. However, patient numbers often decrease during the summer, and how to compensate for this revenue dip during leaner periods is crucial for management stability. Buyers carefully assess the risks posed by such seasonal fluctuations to the business and prioritize the potential for stable, year-round revenue.

As an M&A strategy, it is effective to clearly present initiatives aimed at reducing the risks associated with seasonal fluctuations and enhancing the clinic’s appeal. Specifically, the following approaches to year-round patient acquisition tend to increase valuation:

• Specialized Allergy Clinics: Strengthening services for allergic diseases such as perennial allergic rhinitis and asthma, in addition to hay fever, which can attract patients year-round.
• Sleep Apnea Syndrome (SAS) Clinics: Introducing diagnostic equipment and offering CPAP therapy can establish a stable revenue stream.
• Hearing Aid Consultation Clinics: This is a growing field in an aging society, with potential for regular follow-up visits.
• Dizziness and Balance Disorder Clinics: Specialized diagnosis and rehabilitation can appeal to a specific patient demographic.
• Swallowing Disorder Rehabilitation: New revenue streams can be secured through collaboration with regional elderly care facilities and home healthcare services.

Enhancing these year-round services is highly effective in smoothing out revenue fluctuations caused by seasonality and building a stable management foundation. In M&A, presenting concrete strategies and plans for future year-round patient acquisition, not just past performance, to the buyer can lead to a higher valuation of the clinic’s worth. Please refer to the comparison table below to organize your clinic’s strengths.

Item	Characteristics of Seasonal Revenue	Approach to Year-Round Stable Revenue
Main Conditions	Influenza, colds, hay fever, etc.	Allergies (year-round), sleep apnea syndrome, dizziness, hearing aid consultations, swallowing disorders, etc.
Revenue Fluctuation	Significant annual fluctuations, concentrated in specific periods	Relatively stable revenue expected throughout the year
Management Risk	Difficulty in predicting patient numbers, cash flow challenges	Risk reduction through securing stable revenue sources
M&A Valuation	Cautious evaluation considering fluctuation risks	Stability and growth potential are more likely to be valued

Impact of Medical Corporation Structure on M&A and Succession Procedures

In the M&A of medical corporations, the structure of the corporation significantly impacts the sale process and taxation. In particular, the distinction between “medical corporations with equity stakes” and “medical corporations without equity stakes” directly relates to the succession mechanism and the concept of transfer consideration, requiring thorough understanding beforehand.

For Medical Corporations with Equity Stakes (Transitional Medical Corporations)

Medical corporations with equity stakes allow equity holders to have stakes based on the amount invested at the time of establishment, and to receive refunds (equity stake valuation) corresponding to their stakes upon withdrawal or dissolution. In M&A, succession typically occurs through the transfer of these equity stakes to the buyer. The transfer consideration is generally determined based on the valuation of the equity stakes, but it also incorporates factors such as the clinic’s brand strength, profitability, and future prospects, and can vary through negotiation.

General Flow of Member Change and Equity Stake Transfer:

1. 1

   Preparation and Negotiation of Terms: Both the seller and buyer confirm their M&A intentions and form a basic agreement. At this stage, an estimate of the equity stake valuation and the indicative transfer consideration are discussed.

2. 2

   Due Diligence (DD): The buyer conducts a detailed investigation of the clinic’s finances, legal affairs, taxation, and business operations to assess risks and value. The valuation of the equity stakes is also scrutinized during this process.

3. 3

   Conclusion of Final Agreement: Based on the DD results, the transfer price, transfer date, and other terms are agreed upon, and the final share purchase agreement is executed.

4. 4

   Approval at Member Meeting and Member Change: The general meeting of the medical corporation approves the withdrawal of existing members and the admission of new members. This transfers the operational control of the medical corporation to the buyer. The change of director is also typically carried out at this time.

5. 5

   Registration Change: Changes in members and officers are registered at the Legal Affairs Bureau.

The transfer of equity stakes incurs capital gains tax, making it important to understand the tax implications in advance and take appropriate measures.

For Medical Corporations Without Equity Stakes (Including Fund Contribution Type Medical Corporations)

Medical corporations without equity stakes are non-profit entities where residual assets cannot be distributed to members upon dissolution. Therefore, M&A in the form of equity stake transfer is not possible. The primary method of succession involves the resignation of the current director and officers, and the appointment of new directors and officers, leading to a “change of members.”

The transfer consideration is paid for the assets of the clinic (medical equipment, interior, patient data, etc.) and goodwill held by the current director personally. The assets of the medical corporation itself are not subject to transfer. In the case of fund contribution type medical corporations, the return of funds is possible, but it is limited to the contributed amount and does not accrue interest. The buyer may undertake procedures to return existing funds while contributing new funds.

Succession of medical corporations without equity stakes tends to involve more complex procedures and more complicated valuation of transfer consideration compared to those with equity stakes. In either case, collaboration with experts well-versed in medical M&A is indispensable.

Impact of Medical Fee Revisions, Facility Standards, and Permits on M&A

In the M&A of medical institutions, trends in medical fee revisions, compliance with facility standards, and the status of various permits significantly influence the clinic’s future profitability and business continuity, making them extremely important factors.

Impact of Medical Fee Revisions

Medical fees are revised every two years, involving not only changes in fee points but also the introduction of new additions or reductions, and revisions to calculation requirements. For ENT clinics, fee points and requirements related to specific services, such as sublingual immunotherapy for allergic rhinitis, sleep apnea syndrome diagnosis and treatment, and hearing aid fitting tests, may change with each revision. These revisions directly affect the clinic’s revenue structure, so buyers carefully analyze the latest revision details and future trends when projecting future revenue. In particular, the risk that key services may be subject to reduced points or stricter calculation requirements after succession can affect the valuation of the transfer price.

Compliance with Facility Standards and Maintenance After Succession

Many additional medical fee items are subject to specific “facility standards.” These are requirements related to staffing, medical equipment, and treatment records, and without meeting them, the additional fees cannot be claimed. For ENT clinics, meeting facility standards is essential for providing specialized services such as “ENT Outpatient Surgery Add-on” and “Hearing Aid Fitting Test.”

During M&A, it is necessary to thoroughly check which facility standards the target clinic currently meets and which add-on fees it claims. Even more important is whether these facility standards can be maintained after succession, or if there are plans to acquire new ones. Particularly when the change of physicians alters the presence of specialist qualifications or the number of full-time physicians, the risk of not meeting facility standards must be considered. Buyers factor in the costs and efforts required to maintain these facility standards after succession into the valuation.

Confirmation of Various Permits

Operating a medical institution requires various permits, including the establishment permit based on the Medical Care Act. In M&A, it is essential to confirm that these permits have been properly obtained and renewed.

• Establishment Permit: Confirm whether the clinic’s establishment permit under the Medical Care Act is valid, and whether notification of change of establishment holder or a new establishment permit is required after succession.
• Medical Equipment Permits: Certain medical equipment, such as CT scanners and laser treatment devices, require installation notifications and usage permits. Confirm whether these devices are operated legally and appropriately.
• Narcotic Dispenser License: Physicians handling narcotics and psychotropic substances require a narcotic dispenser license. Confirm whether the succeeding physician holds this license or can obtain it.
• Others: Confirm all related permits, such as permits for the disposal of medical waste and installation notifications for X-ray equipment.

If there are any deficiencies in these permits, it may hinder business continuity after succession, necessitating thorough verification during the due diligence phase.

Response to Capital Gains Tax, Business Tax, and Regional Medical Care Planning

In the M&A of medical institutions, tax implications such as capital gains tax and business tax, as well as compliance with regional medical care planning, significantly influence the decision-making and valuation of the sale.

Treatment of Capital Gains Tax

Upon the transfer of a clinic, capital gains tax is generally incurred by the seller. When selling a sole proprietorship clinic, capital gains from the transfer of business assets are taxed as “business income” or “capital gains.” In particular, capital gains from the transfer of fixed assets such as land, buildings, and machinery may be subject to separate taxation, combined with other income. Tax rates vary depending on the type of asset transferred and the holding period, but generally, income tax and resident tax are levied.

When transferring equity stakes in a medical corporation (with equity stakes), this is considered a “transfer of shares, etc.,” and generally, income tax and resident tax of approximately 20% (income tax 15.315% + resident tax 5%) are levied on the capital gains. However, the actual tax amount can vary significantly due to changes in corporate tax rates and individual circumstances.

To minimize these taxes, it is essential to discuss the form of transfer (business transfer or medical corporation equity transfer), asset valuation methods, and the applicability of tax incentives with a tax accountant or M&A specialist in advance. For example, the interplay with retirement benefits and the utilization of business succession tax systems may be options, but their application is often limited for medical corporations, requiring careful judgment.

Special Provisions for Medical Corporation Business Tax

Medical corporations are generally subject to corporate business tax. However, certain types of medical corporations with high public interest, such as “social medical corporations” and “special medical corporations,” may be eligible for business tax reductions or exemptions. General medical corporations (regardless of whether they have equity stakes or not) are subject to regular corporate business tax, which may include not only income-based but also value-added and capital-based components. When considering a change in corporate structure through M&A, tax advantages and disadvantages should also be taken into account.

Response to Regional Medical Care Planning

Regional medical care planning is a national policy aimed at resolving mismatches between future medical demand and healthcare provision systems by promoting the differentiation and collaboration of hospital bed functions and the advancement of home healthcare. ENT clinics play an important role in regional healthcare collaboration, such as functioning as local primary care physicians, receiving referrals from acute care hospitals, and making reciprocal referrals to specialized hospitals.

In considering M&A, it is also important to assess the positioning of the target clinic within the regional medical care plan and its ability to adapt to future role changes. For example, whether it is subject to the Outpatient Function Reporting System, the extent of collaboration between hospitals and between hospitals and clinics, and the potential for involvement in home healthcare can be attractions or risks for buyers. Clinics that can contribute to maintaining and improving the health of regional residents in line with regional medical care planning tend to be favorably evaluated in the M&A market.

These factors are indispensable for envisioning the stable management and growth potential of the clinic after transfer, and it is necessary to proceed with evaluation from multiple perspectives in collaboration with M&A specialists.
