6 Mission 

7 　　 What Is Merpay? Merpay is a mobile payment service operated by Merpay, Inc., that can be used within the Mercari marketplace app. This service enables users to utilize their Mercari sales balance1, funds added to their Merpay balance from a bank account or ATM, or the BNPL (buy now, pay later) Merpay Smart Payments service to pay for purchases at physical stores and online with their smartphone. Merpay supports both iD contactless payments2 and code payments and can be used at JCB merchants across Japan with Mercard, a credit card with a point-back rate that increases based on use of Mercari and Merpay. 1. In order to use Mercari sales balance, users must configure certain settings or use their sales balance to purchase Mercari points. 2. ”iD” is a registered trademark of NTT DOCOMO, INC. 

8 　　 Mercari Group’s “Circular Finance” The addition of Merpay (money and credit) and Mercoin (cryptoassets) to Mercari’s item lifecycle creates a circular relationship between users’ items, money, and credit, facilitating the growth of “circular finance” that grants users greater freedom and flexibility. It provides users with a valuable, uniquely Mercari experience.

12 　　 Start-up fees 0 JPY Service fee for merchants 2.6% Expanding the Number of Merchants Using Merpay There are no start-up fees for merchants to start using Merpay, and we only charge a fixed fee of 2.6% per transaction. Since September 2020, Merpay and d Payment have used a shared QR code for their mobile payment services. Both companies have also partnered to promote their services to merchants. 

13 　　 Building a Primary-Secondary Distribution Cycle with Mercari and Merpay Receives sales proceeds/adds money to balance Receives item Mercari Group’s services form a sustainable cycle in which users sell things they no longer need on Mercari and use the resulting sales proceeds to shop at physical and online stores (primary distribution) through Merpay. Sells things they no longer need on Mercari Buys new things using Mercari sales balance

15 　　 Merpay Smart Payments— A Credit Service Based on “Trust” Notes: Users 18 or 19 years of age have an upper usage limit of 100,000 yen. (Feature not available to users under the age of 18). Fixed-amount payment not available to high school students. ● Smart Payments enables users to pay for purchases later, with the credit limit determined by their Mercari usage history. ● The service also allows users to set their own usage limit and check their usage history, so they can manage their payments themselves. ● Smart Payments provides flexible deferred payment, installment payment, and fixed-amount payment options, allowing users to adjust repayment amount at any time. ● Users can also use installment payment (two-installment payment) without incurring fees. 

16 　　 Merpay’s Definition of "Trust" We measure “trust” based not on who people are, but on what they have done. We determine whether a user will uphold their promise to repay based on their unique transaction data from Mercari. In this way, we can build trust, creating a new form of credit for the user. Notifies about completed payment Reviews Receives sales proceeds Purchases/pays to Reviews Sends Lister Buyer Length of employment Address Income Occupation Family structure 

17 　　 Increasing Opportunities to Expand AI Credit, the Core of Deferred Payment Services In April 2021, the Installment Sales Act was partially revised, allowing AI to be used to determine credit rather than traditional credit systems. As a result of the new system, business operators began offering small-sum deferred payment services, accelerating the momentum of deferred payment services in Japan. Aug 2021 Merpay acquired AI credit certification - Merpay acquired the first certification on August 27, 2021 - This enabled Merpay to calculate how much a user could affordably be expected to pay based on data such as Mercari usage history Apr 2021 Bill to revise the Installment Sales Act announced A bill to partially revise the Installment Sales Act was ratified by the cabinet in March 2020 and announced in June of the same year Revised Installment Sales Act enacted The revised Installment Sales Act defined the following two points, among others: 1. Introduction of regulations for small-sum deferred payment made in installments 2. Allowance for enhanced screening methods This introduced a registration system for business operators providing small-sum (100,000 yen or less) deferred payment services and enabled the use of AI for credit screenings instead of traditional screenings to determine the amount a user is likely to be able to pay.

19 　　 Deferred Payment Service Usage (Merpay, October 11, 2021: “Survey on Consumption and Payment Methods” (https://jp.merpay.com/news/2021/10/202109bnplsurvey/)) Usage rate of deferred payment services (Single answer/n=800) ■ Has used deferred payment ■ Has not used deferred payment (Usage within the past year) ■ Usage of deferred payment services by age range Percentage of credit card holders among users of deferred payment services (Users of deferred payment services/n=249) ■ Has a credit card　■ Does not have a credit card 30% of people use deferred payment services. This number tends to be particularly high in younger age groups. Over 70% of deferred payment service users have a credit card 

20 　　 Users of deferred payment services are more interested in managing their finances Users Choose Deferred Payment for Ease of Management (Merpay, October 11, 2021: “Survey on Consumption and Payment Methods” (https://jp.merpay.com/news/2021/10/202109bnplsurvey/)) Issues of credit card users/ Reasons for using deferred payment services (Results from respondents in their 20s–30s) Issues faced when using credit cards (Multiple answers allowed / Users of deferred payment services in their 20s–30s / n=111) Reasons for using deferred payment services (Multiple answers allowed / Users of deferred payment services in their 20s–30s / n=46) I end up spending too much It’s hard to tell how much I spent I’m worried about security, like leaks of my personal information or card number ① ② ③ 49.5% 24.3% 19.8% I can change the timing of my payment It’s easy to tell how much I have spent It’s easy to plan ahead for payments ① ② ③ 60.9% 34.8% 30.4% Usage of deferred payment services and interest in managing finances Do you have a system for keeping track of your income and expenses, such as an account book or a notebook?

Respondents who answered that they regularly keep track of their income and expenses using an account book or notebook, a smartphone app, or a computer program such as Excel Deferred payment service users Non-deferred payment service users With credit cards, it’s easy to overuse them.

22 Mercard—Used and Managed in the Mercari app In November 2022, we started providing Mercard, a credit card whose credit limit (up to 900,000 yen) is determined by the user’s Mercari usage history and which can be used and managed within the Mercari marketplace app. Together with the launch of Mercard, we also began offering up to 4% points back when users use their Mercard or deferred payment through Merpay Smart Payments. The point-back rate for purchases made on Mercari can be increased not just by making payments at stores, but by buying and selling items on Mercari. 

23 　　 Launched Mercard Gold in March 2025 2% points-back on everyday purchases Maximum usage limit of 3 million JPY Complete lineup of additional services (Includes shopping insurance, smartphone insurance, travel insurance, and free usage of airport lounges) Bonus point awards according to annual usage No annual fees If card usage is 500,000 JPY/year or more 

24 Significantly Increasing Stores Supporting Merpay Payment In approximately 2 years from the date when all users became eligible to apply, we have issued 4 million1 cards. Mercard allows users to make purchases at approximately 53 million JCB merchants worldwide2, on top of the stores that support code payments and iD payments. Mercard iD payment Code payment 1. Number of cards issued as of November 30, 2024 (approx. two years starting from December 2022, the month of the full release of the service) 2. Number of JCB merchants as of March 31, 2024.

25 The Four Pillars of Mercard Complete the Mercard application from the Mercari app in as little as one minute Point 1 The initial application takes as little as one minute for Mercari users who have already verified their identity (using eKYC). You can receive your card through the mail and start using it in as little as four days. Verified users 17.4 million Visualize and manage your Mercard usage right from the Mercari app Point 2 When your Mercard is used, you will receive an instant notification right to your Mercari app. You can also check your usage history, set spending limits, and make partial payments.

26 The Four Pillars of Mercard Flexibly choose the timing and method of your payments Point 3 Payments are made each month for the amount used in the previous month, but you can use your Mercari sales balance and make payments at any time, from the first to the last day of the month. Furthermore, while you can pay for an entire month of card use at once in a lump-sum style payment, Mercard also allows you to select individual purchases to pay for in advance of others. Benefit from a unique credit system that doesn’t rely only on conventional factors like age and occupation Point 4 Merpay’s credit services are easy for anyone to use, leveraging a unique form of credit based on past Mercari and Merpay usage rather than only conventional factors like age, occupation, and annual income.
