Message from the Chairman of the Board of Directors Mr. Ekniti Nitithanprapas Chairman of the Board 2021 was a year in which the world, including Thailand, remained afflicted by the prolongation of the COVID-19 pandemic, posing a significant challenge to the country’s already slowing economy. However, TMBThanachart or ttb has recognized the role of financial institutions in influencing the economy. It is critical to assist both retail and commercial customers in overcoming economic hardship together and to collaborate with all sectors to support activities that promote economic recovery. All of these efforts were the Bank’s key priorities. At the same time, another bank’s primary mission was to complete the planned merger of TMB and Thanachart Bank. As a result of the merger, TMBThanachart has grown significantly in asset size, customer base, and financial transactions associated with Thai economy. Consequently, the Bank of Thailand announced TMBThanachart as one of the country’s Domestic Systemically Important Banks (D-SIBs), which are critical to the country’s financial stability and economic system. Additionally, the Bank’s credit rating has been steadily increasing since the announcement of the merger in 2019 from three leading institutions: Moody’s Investor Service, S&P Global Ratings, and most recently, Fitch Ratings, which announced an increase of one notch for TMBThanachart’s long-term foreign currency rating from BBB- to BBB in 2021, reflecting the Bank’s increased potential and strength after the merger. Following the “Make REAL Change” philosophy, TMBThanachart is committed to improve the life-long financial well-being of Thai people. At the same time, the Bank has continuously adhered to and placed a high priority on prudent and transparent business practices that are consistent with the principles of good corporate governance and sustainability. Guided by good corporate governance policy, the Bank has consistently enhanced its tight internal control measures to adapt to ever-changing circumstances and comply with international standards. All of the Bank’s efforts are crucial to its robust and sustainable growth and serve the best interests of all the stakeholders as a whole. With its unwavering commitment, the Bank garnered numerous notable awards from a number of distinguished organizations, including the following: • Ranked “Excellence” for “GoodCorporateGovernance” byTheThai InstituteofDirectorsAssociation for the thirteenthconsecutiveyear • Selected for the Thailand Sustainability Investment (THSI) list by the Stock Exchange of Thailand for the fourth consecutive year • Selected for the FTSE4Good Index for the sixth consecutive year • Ranked No. 1 in the Bank’s assessment in compliance with the Fair Finance Thailand guideline for the third consecutive year • Received the Thailand Corporate Excellence Awards 2021 for Financial Management Excellence from the Thailand Management Association and the Sasin Graduate Institute of Business Administration of Chulalongkorn University In terms of social responsibility, the Bank continues to put an emphasis on driving social initiatives. Last year, the Bank’s activities turned to online platforms to keep on inspiring youth and communities in the midst of the COVID-19 crisis. Among the Bank’s activities was the fai-fah learning centers, which shifted to online classes for youth to learn art and life skills. Meanwhile, to maintain community engagement in the face of the pandemic, ttb volunteers worked with communities to help transform them toward sustainability through online consultations and other means. Lastly, I would like to express my gratitude to shareholders, customers, business partners and all of our stakeholders for their continued support, particularly during challenging times last year. I believe that the potential and strength of TMBThanachart’s successful integration, combined with the steadfast commitment of all management team members and employees to Make REAL Change, will serve as a critical driving force in enhancing services and delivering financial solutions and innovations that cater to each customer throughout their life journey, with the ultimate goal of improving life-long financial well-being of Thai people.

Message from the Chief Executive Officer Throughout 2021, the COVID-19 pandemic has continued to persist with broader impacts. However, since the first outbreak in 2020, we have witnessed sustained efforts from all sectors joining forces to solve problems, mitigate impacts and assist those in hardship. Notably, we have observed acceleration of adaptation and steadfastness in the face of a longer-lasting crisis than expected. So did TMBThanachart; we are entirely committed to changing our ways of working and increasing efficiency so that the COVID-19 situation does not constrain nor affect customer services, corporate social responsibility activities through fai-fah program, as well as the integration mission. We recognize that the Bank’s successful merger is an opportunity to fully synergize and leverage the strengths of both banks, which is instrumental in strengthening the Bank’s continued commitment to customers, shareholders, employees, and society. One Bank, One Goal The integration mission began in 2020 with a series of reorganizations and reinforcement of management teams and employees from both banks to serve a business that has grown double in size. Subsequently, the service channels of the two banks were integrated. And in the last six months of the integration plan in 2021, the new bank and new brand were launched concurrently with system integration and the database migration of retail customers, which accounted for the largest customer segment and was the most challenging procedure. In the midst of COVID-19 pandemic, the safety of our customers and employees has become one of the top priorities of the Bank’s merger mission. We enhanced safety measures at our branches to ensure customer safety while expanding and optimizing online service channels to meet an increasing usage and assisting customers in need of financial assistance. In terms of employee welfare, the Bank expedited work system enhancements that enabled employees to work from home at the highest possible rate. Other efforts included vaccine procurement, insurance welfare benefits and care for COVID-19 infected employees. For frontline customer service staff and those involved in the integration processes, the Bankmade significant actions to alleviate the workload burden and created a safer working environment to reduce the risk of COVID-19 infection, such as separation of operating areas, provision of an alternative working location with full accommodation and Bubble and Seal working facilities. Despite a number of challenges and constraints imposed by the COVID-19 situation, our employees were determined and motivated to overcome impediments and achieved the mission of integrating two banks as one on July 5, 2021, as planned. Under this mission, the Bank successfully merged two banks’ databases, as well as migrating the databases of 4 million customers, a loan base of THB 620 billion and a deposit of THB 470 billion from Thanachart Bank to the TMBThanachart system. Furthermore, the Bank enhanced its efficiency after the merger by reducing IT systems and applications of the 2 banks from over 600 to 290 systems and applications. And with the addition of more than 8,000 employees from Thanachart Bank, TMBThanachart now has a total of over 15,000 employees who are essential forces in delivering better financial experiences to over 10 million customers through over 600 branches, ttb contact center 1428, ttb internet banking and the newly-streamlined ttb mobile application. With strong potential of the new merged bank and significantly increased importance to the country’s financial system and economy, the Bank of Thailand announced shortly after the successful integration that TMBThanachart is identified as one of the Domestic Systemically Important Banks (D-SIBs). Additionally, the Bank later received a credit rating upgrade from Fitch Ratings. Prudent Business Operations for Future Quality Growth With the commitment to all stakeholders and being one of the financial institutions critical to the country’s financial and economic system, throughout the COVID-19 crisis, TMBThanachart has adhered to prudent business practices and avoided aggressive growth during unfavorable economic circumstances that could entail greater risks than at time of normal business environment. This is to preserve the Bank’s financial strength and resources for future quality and sustainable expansion. Form 56-1 One Report 2021 9

Mr. Piti Tantakasem Chief Executive Officer With this direction, the Bank therefore prudently grew new loans in 2021, with a focus on low-risk secured lending, namely home loans and hire purchase, which are the Bank’s areas of expertise and we are one of market leaders. At the same time, the Bank continuously enhances loan portfolio quality by providing proactive solutions and de-risking weak loans. As a result of such a direction, the Bank reported total loans of THB 1,372 billion at the end of 2021, which declined 1.5% from 2020. Although loan growth was slowdown, loan portfolio quality was improved in terms of both diversification and staging. This can be indicated by the diversification of loan portfolio to retail-secured loans. And for loan staging, the combination of outstanding stage 2 loans and stage 3 loans reduced by approximately THB 7 billion or 4.4% from the previous year. One the deposit side, the deposit balance was THB 1,339 billion, which dropped 2.5% from 2020 as a result of a decrease in term-deposit balance from deposit optimization post-merger and liquidity management amid a slow loan growth environment. In terms of the operating revenue, the Bank realized the benefits of the balance sheet synergy from deposit and loan optimization post-merger as planned. Nevertheless, due to rising pressure from the COVID-19 situation, operating revenue declined 5.5% from previous year to THB 65,537 million. In such a revenue-constrained environment, cost efficiency was greatly crucial. The Bank executed strong cost discipline and realized the cost synergy from reducing overlapping costs between the two banks on top of boosting operational optimization. As a result, despite additional expenses incurred from the integration, operating expenses were not accelerated. Operating expense was THB 31,219 million, a 3.0% decrease from the previous year. And because the asset quality was managed in accordance with the target, the expense provision was not accelerated and remained at THB 21,514 million, which was slightly lower than in 2020 at THB 24,831 million. However, it was still at a higher level than normal and sufficient to support risks. As a result, the net profit of 2021 was THB 10,474 million, increased 3.6% from 2020. Although the Bank continued to focus on a conservative business strategy in 2021, we have worked diligently to enhance business potential and competitiveness for future growth. Our efforts included establishing business partnerships through an acquisition of a 10% stake in Thanachart Insurance and Thanachart Securities, as well as implementing digital technology to develop new products and services that will be rolled out in 2022. One Goal for Thais’ Life-long Financial Well-being The COVID-19 crisis has highlight financial fragility issues for many of Thai people. And that underscores the importance of our goals: that is, to improve Thai people’s life-long financial well-being. Thus, moving forward, TMBThanachart remains steadfast in the responsibility to raise awareness and educate Thai people about the importance of financial literacy. The Bank also determines to fully leverage great potential from the merger to continuously create financial solutions that improve customers’ financial well-being across all dimensions, including Mindful Spending & Start Saving, Healthy Borrowing, Investing for Future, and Sufficient Protection. Lastly, I would like to thank all of our customers and shareholders for supporting us along our journey of transformation and growth. Additionally, it is indispensable to recognize every one of our employees for their collaborative efforts in shaping TMBThanachart into an organization with full potential and ready to Make REAL Change for Thai people.

fai-fah for Youths fai-fahLearningCenters: Rather thangivingaway freefish, thegoal of all fai-fah learningcenters is to teach youth to fish by encouraging community children aged 12-17 to spend their free time learning art and life skills at no cost. The program’s goal is to inspire youths to use their newfound knowledge to better themselves and their families and create positive change in society. This year, all fai-fah learning centers have launched 3C strategies to inspire youths to work together to overcome the COVID-19 challenge. The 3C consists of the following: 1. Connect: Ensure continued learning by adapting classes (such as art, singing, dance, guitar, and music band) to be entirely online during the COVID-19 pandemic, allowing fai-fah youths to continue studying during the temporary closure of fai-fah learning centers. Additionally, the learning centers offer a variety of activities designed to inspire children and teach financial literacy using an online platform, which keeps fai-fah youths involved in sharing experiences and participating in activities together during COVID-19 pandemic. 2. Care: Provide care to community youths through do-it-yourself activities delivered to their homes via the fai-fah “Happy Box”, which is stocked with equipment for activities that help build art skills and inspire creativity while staying at home, as well as the “Caring Box”, which is filled up with basic medical supplies for children such as face masks and alcohol to keep them safe and “Lunch Box” to support fai-fah youth & families during crisis situation. 3. Contribute: Spread positive vibes through fai-fah Art Fest 2021 in a virtual format to inspire youths to apply what they learn at fai-fah learning centers to sustainably enhance communities and society. By doing this, fai-fah youths will learn how to collaborate online and brainstorm ideas for creative presentations and give back to society in a variety of ways, including designing and producing products for sale using skills learned at the centers, or performing their artistic abilities such as singing, dancing, or sports in the form of video clips to the public online space and generating revenue to support several charities from such creative efforts.
