Expected Effects through This Scheme

‌Shareholder Returns

  • Utilizing ASR will enables the early realization of the benefits of improved capital efficiency through share repurchases.

    What is ASR (Accelerated Share Repurchase)?

    Share repurchase by general market purchases

    Utilizing ASR Share repurchase

    The 2.25 million shares under the ASR framework will be completed

    The remaining shares will be

    purchased by general market purchases

    Point1

    Early completion

    market is the same (5.5 million shares / JPY34 billion)

    immediately

    *Following this acquisition, securities company is scheduled to initiate market purchases to repay the borrowed shares.

    A portion of shares will be purchased immediately, and market purchases for the remaining shares will begin on February 10, with a commitment to the early completion of share repurchase.

    Point 1 On February 9, through ToSTNeT-3, the purchase of 2.25 million shares plus additional shares will be completed immediately through large-lot sale applications from securities company under ASR (ASR limit applied for by securities company + sale applications from other general shareholders).

    Regarding the shareholder return effect on the market, it is equivalent to purchasing the same number of shares by general

    market purchase.

    Point 2 The shareholder return effect from conducting a repurchase of up to 5,500,000 shares / JPY34 billion will be equivalent, and since the share repurchase will be completed immediately, improvements in EPS and ROE can be realized at an earlier stage.

    Use of Funds from Third-Party Allotment

    ‌Capital Alliance

  • Funds raised through this third-party allotment will be allocated to business investments aligned with our growth strategy in anticipation of our next medium-term management plan.

Our group's healthcare logistics service concept is "P&M (Pharma & Medical) Innovation."

We are particularly expanding our handling capabilities in the fields ofhigh–molecular pharmaceutical products,which are expected to see significant market growth. We own high-functionality facilities designed to meet GDP*¹ and BCP requirements, enabling us to provide logistics services tailored to our customers' diverse needs.

  • Established systems compliant with GMP*² and QMS*³, and obtained the necessary business licenses under the Pharmaceutical Affairs Law

  • We offer end-to-end logistics capabilities for pharmaceuticals, medical devices, investigational drugs, and more, from manufacturing to distribution.

  • We have established a high-quality operation system required for handling pharmaceuticals and medical

devices under the supervision of numerous licensed pharmacists, operating from two locations in eastern and

western Japan.

*¹GDP: Guidelines for the Proper Distribution of Pharmaceuticals *²GMP: Good Manufacturing Practice for Pharmaceuticals and Related Products *³QMS: Quality Management standard for Medical Devices and In Vitro Diagnostic Medical Devices

Existing facilities are already operating at full capacity, and it is recognized that expanding capacity at both the eastern and western sites—which will serve as revenue bases in the next medium-term management plan and beyond—is an urgent issue.

With an eye on increasing demand amid an aging population and advancements in medical care, new facility construction plans are underway following land acquisition.

‌Q1

Why did you adopt a method that combines not only regular market purchases but also ASR (Accelerated Share Repurchase/Facility Type Share Repurchase) for the share repurchase?

The aim is to enhance shareholder returns and improve capital efficiency by conducting the share repurchase of an appropriate scale both “immediately” and “with certainty”. Regular market purchases may take a long time to complete, but by combining ASR, the number of shares to be acquired (the ASR portion) is secured

through a sell order from the securities company, enabling the share repurchase to be completed quickly. This allows us to demonstrate our commitment to shareholder returns more clearly to the market.

Q2

What kind of transaction is ASR (Facility Type Share Repurchase)?

ASR (Accelerated Share Repurchase) is a scheme in which a company can repurchase its own shares of the intended size in a short period by entering into a contract with a securities company. While widely used in the United States, its adoption in Japan has increased in recent years. Specifically, the securities company (SMBC Nikko Securities) borrows shares from the stock market and uses those shares to apply for our share repurchase using ToSTNeT-3 (off-auction own share repurchase).

Afterwards, the securities company repurchases shares from the market over a certain period to return the borrowed shares.

Q3

What is the relationship between ToSTNeT-3 and market purchases?

For the share repurchase limit (up to 5.5 million shares), we will first conduct a share repurchase through ToSTNeT-3 on February 9, 2026. Of this, 2.25 million shares are expected to be reliably acquired by using the ASR scheme, in which SMBC Nikko Securities will place a sell order with borrowed shares. Any remaining shares not acquired through ToSTNeT-3, including applications from general shareholders, will be acquired through regular market purchases (discretionary trading contract) from the following day.

Q4

Will SMBC Nikko Securities sell or lend the borrowed shares to a third party in the market?

SMBC Nikko Securities plans to apply the borrowed shares to our share repurchase (i.e., we will repurchase them) and has explained that they will not sell them in the market or lend them to a third party.

Q5

Why are you issuing stock acquisition rights? Will there be dilution of shares?

These stock acquisition rights are not intended for fundraising or new share issuance, but for “post-adjustment of acquisition price” in the ASR transaction. Specifically,

they are exercised to settle the difference between the purchase price in ToSTNeT-3 and the average VWAP during the subsequent market purchase period (ASR). Through this adjustment, our effective acquisition price will be equal to the average VWAP during the period. Even if the stock acquisition rights are exercised and our shares are delivered, this is only an adjustment within the scope of the shares acquired through ToSTNeT-3 in this transaction, so there will be no dilution of shares compared to before the transaction as a whole.

Q6

If the stock price fluctuates, will any gains or losses be incurred to the company?

Settlement is made through the Subsequent adjustment transactions after ToSTNET-3, so the company will not be exposed to a one-sided gain or loss. In all cases, the

economic effect will be equivalent to having “purchased at the average stock price (VWAP) during the period.”

  • If the stock price rises: Our effective acquisition price will also increase, but we will settle by delivering shares equivalent to the price difference to SMBC Nikko Securities (by exercising the ASR Share Options With a Fixed Amount of Investment).

  • If the stock price falls: Our effective acquisition price will also decrease, but we will settle by receiving the price difference in cash from SMBC Nikko Securities (by exercising the ASR Share Options With a Fixed Number of Shares).

Q7

What kind of impact does the market purchases (repurchasing) by the securities company (SMBC Nikko Securities) have on the stock price?

To repay the shares borrowed for sale to our company in ToSTNeT-3, SMBC Nikko Securities plans to purchase shares from the market over a certain period (from August 3,2026 to January 29, 2027). The impact of this repurchase on market supply-demand balance and its economic effect is considered to be generally equivalent to what would occur if we were to conduct a regular market purchase(gradual share repurchase).

Q8

Can general shareholders apply to ToSTNeT-3?

Yes, it is possible. In ToSTNeT-3, sell orders from general shareholders are given priority in matching over those from SMBC Nikko Securities (ASR portion). If there are a large number of applications from general shareholders and aggregate amount of sell orders from the general shareholders and the ASR portion exceeds the upper

limit (5.5 million shares), the shares to be acquired from SMBC Nikko Securities (ASR portion) will be reduced by the number of such excess.
