3 Our Sustainability Approach Environmentally Responsible Operations Through Innovative Solutions Start Here Equal and Inclusive Corporate Culture Starts Here Social Good Starts Here Ethical and Transparent Governance Starts Here Annexes 2022 Sustainability Report Türkiye’s Hepsiburada Message from our CEO Dear Stakeholders, The year 2022 will be remembered as a year of significant developments in many areas, including sustainable development, combating climate change, sustainable and green financing, and organizational environmental, social, and governance (ESG) reporting. A growing coalition of countries, cities, businesses, and other institutions has committed to achieving net zero emissions. Following the Glasgow COP26, COP27 was concluded with countries reaffirming their resolve to limit the global temperature rise to 1.5 degrees Celsius above pre-industrial levels. Environmental reports such as the “Emissions Gap Report,” the WMO’s “Provisional State of the Global Climate 2022,” and the WWF’s “Living Planet Report” have emphasized the need for immediate action to ensure the planet’s sustainability. Furthermore, there have been numerous advancements in ESG reporting both globally and in Türkiye. The European Union formally adopted the Corporate Sustainability Reporting Directive, and the International Sustainability Standards Board (ISSB) published its draft recommendations for new sustainability standards. In Türkiye, with the amendment to the Turkish Commercial Code No. 6102 published in the Official Gazette dated June 4, 2022, and numbered 31856, the Public Oversight, Accounting and Auditing Standards Authority was authorized to set the Turkish Sustainability Reporting Standards. Climate change, and social, digital, and economic inequalities are all on the table today, implying that changes and transformations in the economic and social order are unavoidable. We are on the verge of a significant shift for our planet’s and societies’ well-being and sustainability. At Hepsiburada, we consider sustainability and social responsibility as the core values of our business culture. We have been committed to creating value for our community and contributing to societal development since our inception, while also leading the digitalization of trade. As a technology company, we focus on the constructive, not destructive, power of technology. On the one hand, we use technology to enhance the superior service we provide to our customers. On the other, we lead the development of the sector and digital transformation with our marketplace model that brings together tens of thousands of businesses, our Smart Operations Center, the largest in Türkiye and the region, and our R&D Center, where we develop technologies that raise the bar for other actors. In 2022, with the support of all our stakeholders, we increased our total sales volume by 81% compared to 2021, reaching TRY 47.3 billion. The total number of orders placed through the Hepsiburada platform reached 80.4 million with an 50% increase compared to the 2021,. The number of active merchants on the platform increased by 33% to 99.7 thousand and the number of products rose by 81% to around 163 million. We increased our customer base by 8% to 12.2 million in 2022. Hepsipay, our fast and secure next-generation payment method, has hit 11 million users, marking an important milestone in our journey to becoming a top fintech player and making our customers’ lives simpler with purchasing power solutions. During this time, we succeeded in becoming Türkiye’s “Most Recommended E-Commerce Brand” based on the independent Net Promoter Score (NPS) used to measure customer loyalty and experience, by continuing to differentiate ourselves with innovative services such as Hepsiburada Premium, Return Pick-up, Next Day Delivery, and Buy Now Pay Later. 2022 was a year in which we introduced important innovations. We offered Hepsiburada Premium, the first e-commerce loyalty program planned and implemented in Türkiye, to our customers. We launched Hepsiburada Smart by MIMEX, Türkiye’s first smart and cashless store using artificial intelligence and image processing systems. With the support of Hepsiburada, the first “E-Commerce Competence Center” of the TÜBİTAK-BİLGEM Artificial Intelligence Institute was built as part of Türkiye’s GRI 2-22

Furthermore, we started to work in cooperation with the Turkish Patent and Trademark Office to raise awareness of products with geographical indication through the “HepsiTürkiye’den” program, which aims to help local entrepreneurs use e-commerce to access national and worldwide markets. For Hepsiburada, it was a year in which we took important steps in our sustainability journey. We participated in the United Nations Global Compact, the world’s largest corporate sustainability initiative, and voluntary leadership platform. We have committed to the ten principles of the UN Global Compact in the areas of human rights, labor standards, the environment, and anti-corruption, and we announced to the world that we would work to align our company’s strategy and operations with these principles and would report on our progress in these areas on an annual basis. Also, by signing the United Nations Women’s Empowerment Principles (WEPs), we have committed to abide by seven principles to create corporate policies that promote gender equality and women’s empowerment. In this direction, we were proud to be the only company representing Türkiye in the UNECE Round Table for Gender Equality panel held on 7 April, with Hepsiburada Chief People Officer Esra Beyzadeoğlu. We acknowledge the critical importance of equality and women’s empowerment to a peaceful, prosperous, and sustainable world. We will not relent in our efforts to promote gender equality and women’s empowerment for our female employees, who presently account for 46% of all employees. At every opportunity and in every field, we adopt new approaches that make a difference, such as psychological assistance through the employee support program, physical and social opportunities with a focus on sports, nutrition, family and children through well-being programs, emergency aid funds, career-oriented training programs, special collaborations and career camps for newly graduated female engineers, and we help women to develop themselves with vision, investment, and support. I am pleased to be among the women CEOs, whose number is unfortunately still limited both in Nasdaq, the global technology stock exchange where we are traded as Hepsiburada, and in our country, and I hope that the proportion of women among senior executives will gradually grow both in our country and around the world. As a company founded by Hanzade Doğan, a female entrepreneur, and supporting women in every aspect of the e-commerce ecosystem, we provide significant support to women, women’s employment, and female entrepreneurs, both with our power and funds, and through collaborations with various government agencies, NGOs, and other institutions, particularly financial institutions. Our Technology Power for Women Entrepreneurs initiative has helped over 41,000 female entrepreneurs, nearly 220 women’s cooperatives, and 30 non-governmental organizations since 2017. As a consequence, while women made up 6 percent of Hepsiburada’s business partners in 2017, they now make up 24 percent. Even these figures, as well as the upward trend, demonstrate what ‘Women Power’ can accomplish when given the opportunity to broaden their vision as well as sufficient opportunities and support. Our nation was shaken at the start of 2023 by an earthquake catastrophe that had its epicenter in Kahramanmaraş and affected the surrounding provinces. From the moment the earthquake struck, we launched a wide-ranging effort with all our stakeholders and employees, in collaboration with public institutions and non-governmental organizations, to heal the disaster’s wounds and deliver relief supplies to the region as quickly as possible. At Hepsiburada, in addition to delivering aid to the earthquake zone, we participated in the Earthquake Relief Mobilization organized under the auspices of the Ministry of Trade, which enables our customers to send supplies to the earthquake zone. Our platform also provided our customers with digital support cards that allowed them to donate to AFAD, the Red Crescent, and non-governmental organizations. We mobilized our logistics power and technological infrastructure to provide support to the area hit by the earthquake. We were on the ground 24 hours a day, seven days a week, with our logistics skills, staff, and volunteer teams, delivering relief supplies to earthquake victims in an organized way. Furthermore, we launched the “Every Order Serves as a Support” application on our platform to assist merchants and producers in the earthquake region, and began transferring the entire sales revenue immediately to our business partners affected by the earthquake without any commission or transaction fee deduction. To support the long-term development of the area through e-commerce, at Hepsiburada we are ready to provide technological, logistical, and human resource support and transfer our experience to our merchants who live in the area. I am confident that with collaboration and solidarity, we will get through these difficult times. At Türkiye’s Hepsiburada, we have a strong sense of responsibility, and we will continue to use technology constructively to fulfill our global responsibilities, including those connected to environmental and social issues. With our vision of leading the digitalization of trade, we aim to transparently share the value we have produced in the journey we have been on for more than 20 years with the spirit of innovation and entrepreneurship. In light of this, I am delighted to share with our valued stakeholders our first sustainability report, which we released under the slogan “Transformation for a Sustainable Tomorrow Starts Here,” and wish you a pleasant reading.

Our Sustainability Approach Environmentally Responsible Operations Through Innovative Solutions Start Here Equal and Inclusive Corporate Culture Starts Here Social Good Starts Here Ethical and Transparent Governance Starts Here Annexes 2022 Sustainability Report Türkiye’s Hepsiburada WE HEAL OUR WOUNDS TOGETHER We are deeply saddened by the earthquake disaster that had its epicenter in Kahramanmaraş and affected the surrounding provinces. We extend our condolences to those who lost loved ones and wish all those injured a quick recovery. At Türkiye’s Hepsiburada from on the first day of the earthquake, we launched a wide-ranging effort with all our stakeholders and employees, in collaboration with public institutions and non-governmental organizations, to heal the wounds of the earthquake disaster and to quickly deliver relief supplies to those in need. In addition to delivering urgently needed goods to the earthquake region as quickly as possible, we distributed the products purchased by our customers to the area under the coordination of AFAD within the scope of the Earthquake Assistance Mobilization initiated by the Ministry of Trade. We also offered digital support cards on our platform in cooperation with agencies such as AFAD, Kızılay, Ahbap, AKUT, Haytap, HAÇİKO, Kurtaran Ev, UNICEF, and TOG, allowing our customers to make donations. We prepared and launched an international disaster relief webpage to ensure that people from various countries around the world could help the earthquake area with products and donations. We dedicated 1,500 volunteer workers solely to “earthquake mobilization” activities to reach out to all those who were affected by the earthquake. We also organized a campaign in the name of Hepsiburada and started a relief movement. The total amount of aid provided by Hepsiburada and group company employees reached TL 1.5 million. With our logistical power and operational capabilities, we quickly delivered relief supplies to the provinces hit by the earthquake. We allocated a large number of small vehicles to the area and distributed relief supplies directly to earthquake victims under the coordination of AFAD, in addition to the transportation of approximately 100 truckloads of products. We turned our HepsiJet Adana warehouse into a distribution and coordination center. We also took over the management of three AFAD warehouses in Adana and Hatay in coordination with public institutions for the distribution of relief supplies. We built a system to monitor the inventory, shipment, and coordination of relief supplies using the experience and expertise of our teams. We made this system available to other organizations and users as well. We continue to work in the field with our teams and vehicles through our logistics camp in the region. To help local producers in the area, we began offering their products on our platform without commission, transaction, or service fees, and without any commercial revenue from product sales for Hepsiburada. We have extended our “Every Order Serves as a Support” campaign, which we began with local producers, to include our regional business partners, including producers, merchants, and tradesmen. We also offered free advertising and promotional support to our business partners to help our merchants in the region reach more customers. From the start we took steps to avoid possible price increases for products sold through the Hepsiburada platform and have kept our merchants informed of our efforts. We made a total of TL 150 million in advance payments to assist our merchants in 11 provinces. We organized our efforts and plans for the re-establishment of prosperity in the earthquake region under the “Trade and Technology Power for the Earthquake Region” program to mark Hepsiburada’s long-term commitment to the area. We aim to increase e-commerce sales from the region to TL 10 billion in two years through the program, which includes supporting ten thousand businesses with e-commerce, logistics, and technology opportunities, increasing direct and indirect employment, developing female entrepreneurs and cooperatives, and providing education and social support for children. We are also establishing three new “E-commerce Specialization Centers” in the region as part of the program, which we will execute with a total support package of TL 125 million. We will remain on the ground 24 hours a day, seven days a week, with our logistics capabilities, employees, and volunteer teams, in collaboration with public institutions and non-governmental organizations. We are currently working on an impact report measuring the social impact triggered by our efforts since the first month after the earthquake as well as by the “Trade and Support Power to the Earthquake Region” program launched to contribute to regional development. We will cite this report next year in our Sustainability Report 2023 and will continue to share our efforts transparently. We will get through these difficult times through collaboration and solidarity. 5 2022 Sustainability Report

Alongside the marketplace model, we list and sell products on our platform where “Hepsiburada” is the seller, the Direct Sales model, also known as “1P” or “first party” model, where suppliers (vendors) directly sell products to us on a wholesale basis, and we then store and sell such products to the customers.

From rapid population growth to globalization, from climate change to the extinction of biodiversity, and from digitalization and innovation to socioeconomic inequality, we are witnessing change and transformation in a variety of domains at a faster and more tangible pace. To build a more habitable planet and a more sustainable future, everyone - from governments to businesses, societies to individuals - must adapt to a fast-changing world and the conditions it brings. With the growing digitalization of recent years, particularly after the pandemic, e-commerce sales have more than doubled in the previous five years, and the market is predicted to nearly double again by 2026.3,4 While the industry’s growth has created many opportunities, such as allowing small businesses to access global markets and making people’s lives easier, it has also created a number of environmental concerns, such as increased demand for logistics, more waste, and larger carbon footprints, as well as social concerns, such as occupational health and safety and employee wellbeing. With factors such as greater consumer awareness and stakeholder and investor expectations, the sustainability of the sector is one of the most pressing issues today, and 3 “Here’s why e-commerce growth can stay stronger for longer,” Morgan Stanley, June 14, 2022. 4 Daniela Coppola, “E-commerce as share of total retail sales worldwide 2015–2021, with forecasts to 2026,” Statista, September 21, 2022.

Companies in the sector are now required to carry out operations in a conscious and thoughtful manner that considers their impact on the environment, society, and the economy, as well as to adopt approaches and carry out activities that create long-term value while taking into account and minimizing their negative impacts. At Hepsiburada, we incorporate sustainability into our business practices with the aim of being a part of the transformation and we carry out our activities to create value in collaboration with all our stakeholders. In this context, we shape our sustainability strategy, which we established within the framework of our vision, purpose, and corporate values, around four focus areas. We focus on four aspects of sustainability: The Environment, which entails innovation, efficiency and protection, our People and the Community, which include the human and social dimensions of sustainability, and Governance, which is built upon integrity, transparency and accountability. “Transformation for a Sustainable Tomorrow Starts Here” is our motto in the first sustainability report of Türkiye’s Hepsiburada. We know that it is the responsibility of each and every one of us to maintain our relationships with all our stakeholders based on mutual respect and trust. For more than 20 years, we have been acting according to the highest ethical standards in line with our principles of integrity, transparency and accountability, and we conduct our operations in compliance with all applicable international and national laws. We are aware of our obligation as part of the transformation to leave a habitable planet for future generations and to build a sustainable today and tomorrow. We respect the environment in our operations with innovative solutions, concentrating on protecting natural resources and decreasing our environmental impact on our planet with limited resources, as a firm that focuses on the constructive power of technology. We see social responsibility as a core pillar of our business, and we conduct all of our operations with the intention of creating a positive impact for our stakeholders and promoting societal advancement. In line with our responsible brand approach, we sought to make a difference in our society through collaboration with public and non-governmental organizations to serve various parts of society and create social value through the projects we implement. We consider it one of our most important obligations to establish an inclusive work environment where everyone has equal opportunities and respects differences among our employees, who are the key to our success. We work hard to keep our employees healthy, happy, and motivated by providing a safe workplace that prioritizes physical and mental health and encourages personal development.

To this end, we conducted a materiality assessment to guide us in prioritizing sustainability issues, to help us understand the expectations of our stakeholders and to direct our efforts to the areas where we can create the most value. We assessed the current and potential impacts of material issues—which we will address in a variety of contexts, including the environmental, social, and governance dimensions—on our operations, the impact Hepsiburada has on these issues, as well as the perspectives of our different stakeholders. In this way, this assessment helped underpin our sustainability approach and journey, and guided the development of our first sustainability report. We carried out the materiality assessment in three steps to identify our material issues. In the first step, we aimed to identify the potential material issues by conducting an external environmental analysis. In this context, we reviewed our impact across our entire value chain and used SASB (Sustainability Accounting Standards Board), S&P (Standard & Poor’s) and MSCI (Morgan Stanley Capital International) material issues for the sector. We also conducted a benchmark study by examining the sustainability activities of organizations operating in our sector. Based on this research, we have identified potential material issues in the environment, employee, community, and governance focus areas. 1. IDENTIFICATION OF POTENTIAL MATERIAL ISSUES • We looked into the sectoral material issues published by indices such as SASB, MSCI, S&P. • We conducted a benchmark analysis to evaluate sectoral focus areas and best practices. • With the external environmental analysis we conducted, we identified the potential material issues in line with Hepsiburada’s sustainability approach. 2. CONSULTING INTERNAL AND EXTERNAL STAKEHOLDERS • We reached more than 6,000 internal and external stakeholders through surveys, sharing a list of potential material issues and seeking their views. • We consulted the C-level executives to ensure that potential material issues are also reviewed by the senior management. 3. CREATING THE MATERIALITY MATRIX • We conducted a study in which we assessed the priority of each of our key stakeholder groups. • We created the materiality matrix using all the inputs we obtained through surveys and external environment analysis. • Finally, we presented the matrix and results to our senior management for their approval.

As part of the second step, we also consulted our senior executives to determine the importance of the material issues for Hepsiburada. In the final step, we began working on the matrix using the inputs obtained from external environmental analysis, executives’ opinions, and internal and external stakeholder surveys. In this context, we performed a study in which we assessed the importance of each key stakeholder group for us and reflected the perspectives of our internal and external stakeholders in our matrix based on the study’s findings. Finally, we presented the matrix and results to the senior management for their approval. This matrix, which includes the materiality assessment results, guides us at Hepsiburada in our sustainability journey in terms of how we should use our resources, where we should focus on improving ourselves, and how we can create value for our stakeholders. The material issues were color coded as “Environment,” “Employees,” “Community,” and “Governance” in the matrix generated based on the assessment outcomes. At the same time, we have categorized the issues according to their weight as “Level One”, “Level Two”, and “Level Three” and accordingly, we have included our activities on these issues in the relevant sections of the report.

The report proposes two different and complementary approaches. One is to include independent directors with diverse experience, skills and interests who can reflect the priorities of a wider range of stakeholders rather than just shareholders. The other approach is to redefine corporate governance principles to take into account stakeholders instead of shareholders.5 In the light of all these outcomes, we know that it is not possible for organizations to survive on their own. Growing hand in hand with different stakeholders and working towards the same goals are what strengthens and sustains companies. At Hepsiburada, we identify our stakeholders who have a direct impact on our work, and we pay attention to interact with them on a regular basis. We engage with our stakeholders through various communication channels and empower them to contribute to our processes by seeking their input. We asked our stakeholders what topics should be on our agenda with the understanding that they will serve as our best resource in selecting our sustainability material issues. To assess their inputs, we grouped stakeholders into several focus groups and adjusted their contribution rates in our impact matrix in accordance with this grouping.

Because of the greenhouse gases emitted into the atmosphere since the industrial revolution, the average global temperature has increased by about 1.07 degrees Celsius with regional variations.6 Climate change threatens life on Earth by triggering a wide range of environmental changes, including reduced biodiversity, harder access to clean water, rising sea levels, and increased likelihood of a range of climate hazards, including extreme heat, desertification, and extreme weather events. The need to reduce our environmental impact to tackle the climate crisis, one of the most pressing challenges of our century, concerns all sectors, including the e-commerce sector, companies, public institutions, academics, and society. We are all responsible for creating a paradigm of sustainable development that is not harmful to the environment. At Hepsiburada, we understand that as we grow, we need to create value while remaining environmentally conscious. We are aware of our obligation as part of the transformation to leave a habitable planet for future generations and to build a sustainable tomorrow. That’s why we focus on conserving natural resources and reducing our environmental impact on a planet with limited resources. While growing together with our stakeholders as a pioneer in Türkiye’s digitalization process, we strive to develop innovative and efficient solutions that reduce our environmental impact by harnessing the power of technology. HEPSIBURADA’S CARBON FOOTPRINT Governments, the private sector, and communities must all work together to cut greenhouse gas emissions, which accumulate in the atmosphere and cause the surface and the oceans to warm rapidly. Particularly in recent years, many countries have implemented emission trading schemes, carbon or energy taxes, regulations and standards on energy efficiency and emissions. In addition to being prepared for future national or regional climate policies, businesses must manage environmental risks and minimize greenhouse gas emissions to achieve long-term and sustainable prosperity. Knowing that precisely measuring the greenhouse gas emissions resulting from our activities is the first step in assessing our environmental impact and developing action plans, we calculated our carbon footprint during the reporting period. IN ORDER TO ASSESS OUR ENVIRONMENTAL IMPACT AND DEVELOP ACTION PLANS, WE CALCULATED OUR CARBON FOOTPRINT DURING THE REPORTING PERIOD. 6 IPCC, 2021: Summary for Policymakers.

In line with the measurement guidelines of the Greenhouse Gas Protocol (GHG) standard developed jointly by the World Business Council for Sustainable Development (WBCSD) and the World Resource Institute (WRI), we have calculated our Scope 1, 2 and 3 emissions after an intensive data collection and calculation process for the past 3 years, including the reporting year of 2022. You can access detailed indicators of our energy consumption and emission data in the Environmental Performance Indicators section. COMMON BARCODE SYSTEM We developed a Common Barcode system to increase efficiency in our sales operations and shorten the processing times in the warehouse. With this system, Hepsiburada’s own barcodes are printed at the same time as the corporate barcode of the cargo company assigned to the order, saving the printing of more than 700,000 labels every month on average. This practice helps us to reduce our environmental impact by saving both time and materials when fulfilling our warehouse orders. In the first stage of the project, we started to use common barcodes with the cargo companies we were working with, and later we switched to using the common barcode with our retail suppliers as well. Next, we will include the infrastructure of all direct sales operations and marketplace merchants in this system, which will allow us to make these savings sustainable in Hepsiburada Ecosystem. HEPSIMAT As part of our delivery services, we launched the HepsiMat solution to create a network of collection points where customers can pick up their purchases. With HepsiMat points, where we deliver more than 3 thousand orders daily, we offer our customers alternatives in terms of cargo delivery time and place, enabling them to receive their orders from a delivery point outside their homes and workplaces at any time they wish. Through over 3333 HepsiMat points across Türkiye, we offer all the companies and institutions we work with, from shopping malls to gas stations, grocery stores to stationery stores, the opportunity to enrich the service they provide to their existing customers while also helping to increase the vitality of their stores and enabling them to grow. In addition, we ease the burden on cargo companies by increasing the number of HepsiMat delivery points.

However, with rapid population growth, economic growth and increased consumption, there has been a significant increase in the rate of consumption of natural resources. Today, at the current rate of consumption, the demand for natural resources exceeds 41% of the world’s idle capacity.7 The fact that the Earth Overshoot Day, which has been occurring earlier and earlier for years, took place on July 28th in 2022 shows us how fast we are consuming a year’s worth of natural resources that our planet has to offer. This leads to increased pressure on natural resources such as land, water and air, and destabilizes natural systems as a whole. To live without exceeding nature’s capacity to replenish its own resources and to leave a habitable world for future generations, we need to use our resources efficiently. At Hepsiburada, we focus on conserving natural resources and reducing our environmental impact on a planet with limited resources. We make use of old electronic products through our Refurbish the Old project, support the local economy through the HepsiTürkiye’den program, while encouraging the consumption of local products. We produce solutions that optimize the use of materials with our responsible packing and packaging practices, and we reduce our environmental impact by adopting more efficient and innovative management ways for existing resources. REFURBISH THE OLD As a result of rapidly developing technology and changing consumption habits, we are rapidly replacing the electronic devices we use, buying new ones and discarding old ones. In this unsustainable cycle, electronic devices, which often end their journey in landfills, become part of the rapidly growing hazardous waste problem on our planet. At Hepsiburada, with our Refurbish the Old Project, which we launched in 2020, we take old devices from our customers’ homes and refurbish/ reuse/recycle them, and in return, we offer gift vouchers or cash payments or the opportunity to buy a new phone. We refurbish/reuse/recycle old devices in line with the procedures determined by Hepsiburada and its business partners, thus contributing to the circular economy, which is necessary for sustainability, by ensuring that they are brought back into the economy. In this project, the number of applications has increased by 258% since the beginning of 2022 and we have reached 73 thousand customers and 124 thousand applications. 7 Emergency, 9. (2015, July 8).

Our customers are aware of the environmental impact that packaging creates, and act accordingly, and they also expect us to deliver their purchases safe and sound. Even today, when new packaging technologies and recycled and/or recyclable packaging materials are rapidly becoming widespread, packaging still has a take-make-waste life cycle. In this cycle, known as the linear economic model, raw materials taken from nature are returned to nature as waste after a short lifespan, resulting in considerable usage of natural resources and the production of large volumes of waste. Of course, we need packaging to deliver orders safely and undamaged to our customers, but in a world with limited resources and a growing waste problem, we also need to shift toward environmentally friendly practices, reduce our packaging volumes, and adopt circular models that reduce or eliminate waste. At Hepsiburada, we conduct research and development to develop responsible, sustainable packing and packaging solutions that we can integrate into our operations. We produce solutions that optimize the use of materials by harnessing the power of technology, and we reduce our environmental impact by adopting more efficient and innovative management options for resources. We use two different materials in our packing processes: paper-based parcels and plastic-based PVC to prevent problems such as breakage and leakage. When an order is received, the products are brought from the shelves to the packaging area in our fulfillment centers, and we ensure that the products IN 2022 APPROXIMATELY 934 THOUSAND KILOGRAMS OF PACKAGING WASTE WAS RECYCLED. WE ENSURE THAT WASTE IS NOT SENT TO LANDFILLS, WHILE ON THE OTHER HAND, WE REDUCE OUR ENVIRONMENTAL FOOTPRINT CAUSED BY WASTE. are packaged in the most appropriate way using software developed by Hepsiburada engineers, which specifies which parcel or package the products should be placed in with the least amount of packaging. The shrink machine is used especially for packaging liquid products and enables us to handle them in the most efficient way, so we both achieve financial savings and minimize waste. In our direct sales model, retail suppliers send the products to our fulfillment centers in paper and plastic packaging to ensure safe and undamaged delivery. To keep waste packaging materials from going to landfill after products are unpacked and placed on the shelf, we send this valuable waste, as well as all packaging waste generated in our fulfillment centers, to licensed recycling facilities and ensure that they are brought back into the economy in line with the circular model. With this method, we ensured that approximately 934 thousand kilograms of packaging waste was recycled in 2022. Thus, on the one hand, we ensure that waste is not sent to landfills, while on the other hand, we reduce our environmental footprint caused by waste. 2020 2021 2022 623,994.15 1,801,065.06 701,384.77 920,056 1,610,514.56 Packaging Materials (kg) Paper Plastic GRI 3-3, GRI 301-1, GRI 301-2, GRI 301-3

As consumption rises, waste that is not properly managed ends up in landfills, rivers, seas, and oceans. Today, on average, we generate close to 2 billion tons of waste globally.8 This has environmental, economic and social consequences beyond national borders, affects human health and quality of life, causes soil and water pollution, deterioration of air quality. Due to the irresponsible use and waste of resources, we are exploiting unsustainable amounts of natural resources to keep up with increasing consumption and pushing the limits of our planet.9 To tackle the growing waste problem and leave a habitable world for future generations, we urgently need to shift from the linear economic model of “take, make, waste”, where natural resources are taken and turned into products and then landfilled, incinerated or left to mix with nature, to widely recognized sustainable alternatives such as the waste hierarchy and circular economy approaches. While the waste hierarchy approach prioritizes waste prevention, reuse, recycling, and recovery over disposal, the circular economy approach encourages products to be designed to reduce waste, products and production materials to be used as long as possible, and end-of-life products to be recycled back into the economy. At Hepsiburada, to reduce the environmental impact of our operations caused by waste, we carry out studies to reduce the LINEAR MODEL CIRCULAR MODEL Take Take Make Make Repair Recycle Reuse Use Use Waste use of resources, separate the wastes at the source and bring them back to the economy through reuse and recycling, and we consider sending the wastes to landfill as a last resort.

Furthermore, waste from excess inventory, such as overstocked, returned, damaged, or expired products, is carefully managed. We reintroduce returned products, especially electronic ones, which are returned due to problems such as breakage and deterioration in cargo and other reasons, to the economy by outlet sales We send expired products from our fulfillment centers to recycling facilities. In 2022, we sent 21 thousand kilograms of food waste to recycling. In order to increase the lifespan of the wooden pallets we use for transporting products and bringing them to warehouse centers, we repair and reuse broken or damaged pallets. We stop harmful substances from contaminating the environment by shipping detergent and other chemical items -whose packaging is broken, damaged, or rendered useless during transport- to recycling facilities. In 2022, we sent 78 thousand kilograms of chemical waste to recycling. We have a second-hand shop inside our fullfilment centers for Hepsiburada blue collar workers.

By 2050, transportation emissions are expected to more than double compared to 2015 due to a number of factors, such as population growth, demographic shifts, increased consumption brought on by economic growth, the expansion of the transportation industry, and the demand for transportation in both developed countries seeking to sustain economic growth and in developing countries where many people are gaining access to the global markets for the first time.11 Due to its dependence on fossil fuels and direct greenhouse gas emissions, the transportation sector, which has been expanding quickly over the past few decades and is predicted to do so in the future, indirectly contributes to global warming while also having an adverse impact on human health through noise and air pollution. To address climate change, one of the most pressing issues of our day, the transportation industry must undergo significant transformations to meet the objective of limiting global temperature rise to 1.5 degrees Celsius. In the increasingly competitive environment of the e-commerce sector, in which long-distance, regional and intra-city transfers as well as last mile delivery are all relying on transportation, companies are expected to meet customers’ expectations for fast, practical, transparent, and flexible delivery, as well as the increasing demands of investors, customers, and other stakeholders, while implementing sustainable strategies and practices that consider the environmental and social impacts of their activities. At Hepsiburada, with our seven fulfillment centers covering a total area of 143.5 thousand square meters, including our Gebze fulfillment center, which is our largest storage center, and Tuzla, Ankara, İzmir, Adana, Diyarbakır and Erzurum fulfillment centers, we conduct our Hepsilojistik operations, which provides logistic support for the pre- and post-sales processes of our corporate customers, including product entry, transportation, addressing and counting, customer order management, order picking, packaging and invoicing, shipping, delivery to customer and customer return processes. We serve more than 1500 e-commerce partners in distribution and delivery processes through HepsiJET operations in our 18 transfer centers and 192 branches in 81 provinces. We take a responsible approach to the environmental impact of our extensive logistics, distribution, and delivery network, and utilize the power of our technology to be a part of the sustainable transformation and continue our efforts to reduce our environmental impact by improving our operational efficiency and effectiveness through innovative approaches. LOGISTICS CARBON FOOTPRINT While providing our clients throughout Türkiye with a variety of delivery options to ensure that their goods are delivered quickly and safely, we also strive to reduce the environmental impact of our transportation activities through innovative solutions. Since the first step to be taken in this direction is to fully measure our environmental impact by using the right calculation methods, we conducted a carbon footprint mapping study in 2022 and analyzed the emissions arising from our logistics and transport activities.

Therefore, transportation, which has a significant share in our operational activities, accounts for 70% of our energy consumption and 90% of our Scope 1 emissions. Meeting the increasing transport needs of the e-commerce sector, which gained momentum with the Covid-19 pandemic, with sustainable and innovative technologies has brought along an increase in our customers’ demand for more environmentally friendly delivery options. Considering these factors, we are aware that we need to take part in the transition to green transport by adopting efficient fuel consumption practices globally and using low or zero-carbon fuel. In our country, where the infrastructure for the use of electric vehicles and access to electric vehicles with the capacity suitable for the cargo sector is limited, we have a long way to go before the widespread adoption of zero-carbon transportation operations. Therefore, we focus on reducing emissions from our vehicle fleet with different process optimization projects. We carry out more effective operations at lower prices by locating our transfer centers in suitable residential areas around our country, and we save energy, fuel, and costs by moving large quantities of goods to the nearest locations. With our transfer centers opened in 2021 Kayseri, Merzifon, Düzce and Bursa, we reduced our carbon footprint by driving approximately 1 million kilometers less during the reporting period. In the coming periods, we aim to expand sustainable logistics and transportation activities by continuing to conduct route optimization and efficient fuel use projects. HEPSIJET TRANSPORTATION OPERATIONS OPTIMIZATION At HepsiJET, we aim to provide quality delivery services that creates added value for our customers. We conduct research on the accurate generation of vehicle routes and loading optimization in order to manage the large transportation volumes resulting from our rapidly expanding customer portfolio and increasing e-commerce shopping in Türkiye, as well as to transform our transportation model into a more flexible and faster distribution model. Thanks to the projects we carry out in this context, we are able to optimally create cross-dispatch12 and time-window routes, perform accurate loading and offer a fast, error-free, and punctual delivery service. In addition, we aim to save costs and fuel and reduce emissions from our processes by using the right number of vehicles and the most accurate route. MULTI-VEHICLE ROUTE OPTIMIZATION With HepsiJet’s new “Multi-Vehicle Route Optimization” technology, we ensure high efficiency in delivery processes of cargo orders. In this innovative system, registered by TURKPATENT, HepsiJet engineering team was inspired by the natural miracle and instinct of ant colonies carrying food to their nests. This system creates a model according to the priority of the shipments and distance matrix between the delivery and receiving points of the orders. An innovative multi-vehicle distribution scenario is achieved by calculating the delivery costs of each possible route and making a single route to all locations in the set of delivery addresses.

DELIVERY MANAGEMENT SYSTEM 4.0 To manage the expanding capacity without lowering customer satisfaction, we developed a Delivery Management System with our own resources as part of our HepsiJet operations, which quadruple the number of shipments delivered each year compared to the preceding year, With this system, we were able to make planned technological improvements, integrate automation technologies, increase package traceability, communicate the expected arrival time to customers, provide a payment-at-the-door option, and build mobile solutions that streamline our operations. This helped us to develop the infrastructure of a Delivery Management System that is equipped with algorithms to cover the needs of customers from end-to-end at a national scale. We established a win-win model between customers, carriers, and the business thanks to the prevention of process inefficiencies, thereby assisting in the growth of the e-commerce ecosystem. Our solutions for capacity prediction and route optimization developed with the use of machine learning algorithms, improve resource efficiency, while reducing our environmental impact. IDENTIFYING COMPANY WORKING ZONES THROUGH OPTIMIZATION AND MACHINE LEARNING With the aim of delivering goods on time as the volume of shipments and the number of couriers working in branches increased, we launched a project called Identifying Company Working Zones in 2022 to calculate the positioning of HepsiJET’s branches and identify the working zones of the couriers. Thanks to the algorithm, we ensure that the courier zones are generated automatically, and the work is WE IMPLEMENTED OPTIMIZATION AND CAPACITY MANAGEMENT FOR FAST DELIVERIES WITH TIME WINDOWS PROJECT WHIC WAS FUNDED BY TÜBİTAK IN 2022 TO REALIZE FASTER DELIVERIES. allocated fairly among the couriers with little updates, even in constantly changing volumes. Furthermore, we improve courier satisfaction, transit time, and quality, and strengthen our customer communication. By keeping innovation at the forefront, this project fully adapts to the large volume changes in the industry and changing field operations, providing data for machine learning to help us create zones more efficiently and improve our operational efficiency by making forward-looking predictions. OPTIMIZATION AND CAPACITY MANAGEMENT IN FAST DELIVERIES WITH TIME WINDOWS We observe that the time windows for the delivery of e-commerce products are shrinking and the expectation of fast delivery is increasing gradually. In this respect, in addition to the services offered by HepsiJET, we implemented Optimization and Capacity Management for Fast Deliveries with Time Windows in 2022 to realize faster deliveries such as within an hour, and two hours, as well as deliveries within one hour after the order. With this project, which we began in 2019 and was funded by TÜBİTAK, we seek to address the problem of time window compliance in delivery, one of the issues in the developing e-commerce sector in our nation and contribute to the sector’s growth with domestic technologies. At the same time, we believe that this project will open the door for Türkiye’s retail industry to increasingly rely on smaller supermarkets and more efficient and smaller warehouses instead of large supermarkets. In this way, we ensure fast deliveries that meet customer expectations, as well as reducing the environmental footprint with properly positioned, efficiently managed smaller storage areas. GRI 305-5

More than 2 billion people live in water-stressed regions of the world today, and more than 3.6 billion do not have appropriate access to water for at least one month out of every year.13 Access to clean water may become even more challenging in the upcoming years due to rising demand brought on by urbanization, rapid population growth, and expanding demand in numerous sectors. Consequences of climate change, such as shifting precipitation regimes, extreme weather events, floods, and droughts are estimated to worsen water stress. By 2050, more than five billion people are projected to lack adequate access to water for at least one month a year.14 Ensuring access to safe and clean water for all, which is one of the United Nations Sustainable Development Goals, is crucial for the sustainability of natural resources as well as economic and social development. In this context, at Hepsiburada we consider water consumption as one of our sustainability material issues and we attach importance to the efficient use of water, one of our limited resources. Although our water use is low due to the industries in which we operate and our business model, we use water for residential reasons in our offices, fulfillment centers, and branches. To ensure efficient use of water, we have carried out many projects such as faucet systems with contact sensors.

According to McKinsey & Company’s 2020 report titled “Diversity Wins: How Inclusion Matters” published by McKinsey & Company in 2020, the study, based on data from more than a thousand large companies from 15 countries, shows that companies with high in-house diversity have higher profitability performance than their competitors with relatively less diversity.15 Again, in the “Women in Workplace 2022” report, where McKinsey & Company published the results of its survey with more than 40,000 employees of 333 companies in the United States, it is emphasized that after the pandemic, women changed jobs faster than men against the in the face of the current status quo trend and began to prefer more equal and inclusive companies, pointing out that more egalitarian companies find it easier to retain talented women in their organizations.16 With the vision of a future where everyone is equal, we are working hard at Hepsiburada to make our human-centered corporate culture more inclusive and equitable. We are creating a workplace where social inequities are removed and every employee can showcase their talents while being treated fairly thanks to our inclusive and egalitarian attitude. GENDER EQUALITY Since the day we were founded, we have advocated for gender equality and women’s empowerment in a wide range of fields ranging from entrepreneurship to employment, education to art, in order to secure long-term economic growth while pioneering trade digitalization. in 2022, we took another step and became a signatory of the United Nations Women’s Empowerment Principles (WEPs). The Women’s Empowerment Principles, developed in 2010 as a joint initiative of the United Nations Global Compact (UN Global Compact) and the United Nations Entity for Gender Equality and the Empowerment of Women (UN Women), are widely regarded as one of the most important global initiatives aimed at advancing gender equality and enabling women to participate in economic life in all sectors and at all levels. 15 Dixon-Fyle, S., Dolan, K., Hunt, D.

In this regard, we provide our employees with the opportunity to grow in all areas through our 360-degree performance management system, which recognizes success and focuses on areas that need improvement. We also provide training opportunities that are in line with the competencies and career goals of our employees. PERFORMANCE MANAGEMENT SYSTEM At Hepsiburada, we owe our successful and sustainable performance to our employees. With our performance management system, we support the performance development of our employees by monitoring their competences throughout the year in line with the set targets. The Performance Management System consists of target setting, follow-up meetings, presentation of target results, evaluation process, calibration and feedback processes throughout the year. In the first step of this process, each employee creates between 4 and 6 targets in parallel with the targets of their managers. After these targets are approved, the employees and their managers manage the process together through target tracking meetings, and the results are presented and evaluated in the next stage. Through meetings with senior management, all employee results are evaluated to develop performance calibrations, which are then shared with employees through feedback sessions. Timely and appropriate feedback, which also constitutes our HR strategy, is the top priority we attach importance to in this process. Thus, we quickly identify areas open to improvement and take action to make employee performance even more efficient. In 2022, the ratio of employees evaluated within the scope of our Performance Management System was 84%. In the coming period, we aim to include all our employees in our performance management system and integrate this process into our inclusive business culture.

In light of this, we created the Hepsinstitute Corporate Academy. We adopt a continuous learning approach and support the development of the professional competencies and managerial skills of our employees with application methods that are independent of time and location. In development programs where we adopt a blended learning model, we provide our employees with in-class and virtual classroom training as well as online training offered through various digital development platforms such as Hepsinstitute, Udemy, Pluralsight and Open English. Our Development Model and Programs We provide our staff with 4 primary categories of development programs, which promote ongoing and all-encompassing development. Leadership Development In addition to ensuring that our managers develop their fundamental leadership skills, the Hepsinstitute Leadership Academy program, which is open to managers at all levels, aims to develop the behaviors expected of the Hepsiburada leader profile in the process of achieving our company’s strategic goals and to establish a shared, long-lasting leadership culture. The program consists of self, business, and team leadership modules designed for each level of management, as well as virtual seminars, inventories, group coaching, and numerous reinforcing videos and applications. Talent Development With the program we call “Young Talent, Your Future is Here”, we aim to introduce Hepsiburada culture to young talents who have recently joined us and to provide them with the skills that will prepare them for business life. In this program, our young colleagues participate in a comprehensive development program lasting about 6 months. We also ensure that each of our young colleagues are assigned development coaches who will support them to adapt easily to our working environment and culture, to understand our end-to-end processes, and to guide them through the program efficiently. Competency Development Competency Catalogue trainings designed to ensure that the defined Hepsiburada competencies are adopted and transformed into behaviors by all employees. Every year, employees are evaluated based on these competencies and are included in development programs related to competency areas open to improvement. Professional Development This category includes functional training programs designed to support the professional development of employees, tailored to the changing needs of departments each year. In this category, we also include English training programs that primarily cover employees who are expected to use English actively in their work. Employees participate in English training programs tailored to their needs and levels. Internal Trainer Development Programs, which assist learning from one another and developing together within the organization by sharing expertise and experience, are also included in this category. Corporate Development This category includes the Digital Orientation Program, which is assigned to our new colleagues on the first day of their employment via the Hepsinstitute Development Platform, as well as the mandatory trainings that all employees must receive in order to comply with our legal obligations and to advance our corporate development.

47 Türkiye’s Hepsiburada Our Sustainability Approach Environmentally Responsible Operations Through Innovative Solutions Start Here Social Good Starts Here Ethical and Transparent Governance Starts Here Annexes 2022 Sustainability Report Equal and Inclusive Corporate Culture Starts Here Your Future Starts Here One of the pillars of our inclusive culture is the identification and hiring of young and energetic talent for our Hepsiburada ecosystem, which is expanding in the rapidly rising e-commerce sector. In this context, we come together with young people through our university collaborations. We got the opportunity to connect with students at several university events, ranging from career fairs to data science lectures and seminars, MBA (Master of Business Administration) courses to coffee chats, and Hepsiburada has participated in over 90 university events in total. Our “Your Future is Here” internship program, which began in 2021, serves the targeted student demographic through our website, campus events, and social media profiles. In the first semester of the program, we received applications from approximately 5000 students. We accepted 84 students into the program by exposing our young talent candidates who applied first to a general aptitude exam, then to case study processes, and finally to an interview with Human Resources and unit managers. In the framework of the program, we introduced our Hepsiburada corporate culture by building competence through project work, in addition to trainings in many areas ranging from personal growth to professional development. We have included the candidates who successfully completed these studies into our full-time staff at Hepsiburada. We hope to uncover bright university students before they graduate, bring them into Hepsiburada, and give them an opportunity for development at the start of their career journey by repeating the “Your Future is Here” program every year. Data Science Software and Coding Trainings We understand the necessity of digitizing business operations in today’s quickly evolving technological environment, and we take care to bring together outstanding young people who want to advance their careers in data science and software. We collaborate with a number of prestigious educational institutions to give university students data science and software training as well as case studies. In 2022, we assisted students who successfully finished data science and data engineering training and case studies that we arranged in collaboration with Istanbul Data Science Academy. In the same year, we completed Back-end Developer, Front-end Developer, iOS ve Android Developer bootcamp classes with Kodluyoruz Patika.dev. Through these partnerships, we had the chance to reach more than 1200 students and included 112 of them in the programs. We offered full-time positions to 23 students who completed the case analysis and bootcamp studies with outstanding success. In addition, we created 16-week application-oriented data analysis programs in collaboration with Upschool to enhance the employment of female engineers, and we recruited two students who successfully finished these programs. University and High School Collaborations While designing the Hepsiburada of the future, we always focus on young people. We strengthen our bond with students by taking part in high school and university activities. In 2021, we set up booths at more than 90 university events, and in 2022, we set up booths at 45 university events and communicated one-to-one with university students and introduced Hepsiburada to them. We also participate in data science courses at Galatasaray University, Koç University and Sabancı University and share our experiences with students. In this context, we organized the event “What we saw in academia, what happened in the sector” at Galatasaray University to share our experiences in the sector. We give an opportunity to students to practice with problem analysis and solution development processes through teamwork by organizing case studies in both our university and high school events. Since 2021, we have contributed with our own case study to an event hosted by 2 different high schools (Istanbul Erkek Lisesi and Hisar Schools) in 3 different organizations where students from Türkiye’s leading successful high schools come together and work on case studies. We participated in these case study competitions as a jury and made evaluations and participated in brainstorming activities with the students. In addition to the case studies, we sent speakers to career events at Galatasaray High School, Koç High School, Istanbul Erkek High School, and Hisar Schools, and we organized question and answer sessions for high school students to help them make the right career choices and answer their questions.

We believe in the importance of adopting responsible brand awareness efforts to ensure that children can enjoy this right. On April 23rd National Sovereignty and Children’s Day, we launched the “A Smile is Enough” project together with AÇEV, İhtiyaç Haritası and Yarına Umut Ol Association inspired by children’s smiles and reached 32 thousand children from 202 schools. We continued the project time to time (April 23rd, Ramadan Feast, Disability Week, Report Card Period, Back to School) and brought thousands of quality books, stationery and toys to children studying in village schools all over Türkiye. During the back-to-school season, Hepsiburada delivered 5000 stationery sets to children in need and urged our customers to help by visiting the support page we built, and we reached 1300 additional students by collecting over 100,000 liras of support. So far, we have reached 32 thousand children from 202 schools with the aim of minimizing the inequality of opportunity experienced by children who have difficulty in accessing books, stationery and toys. Our goal is to expand this project across the country and make 1 million children smile. Because A Smile is Enough, a smile is worth everything! OUR COLLABORATIONS WITH NGOS AND SOME OF THE PROJECTS WE CONDUCTED: Turn on the Red Light for Autism The Tohum Autism Foundation promotes the early detection of children with autism spectrum disorders, as well as their special education and inclusion in society, and aims to expand these efforts to the entire country. At Hepsiburada, we launched a campaign on April 2, World Autism Awareness Day. Communication, speech and social skills trainings, which are important for children with autism, contribute to the integration of children into society as independent individuals. As part of the campaign, every purchase made in the Hepsiburada children’s clothing category between April 1-3 supported the education scholarship of a child with autism and his/her family in cooperation with the Tohum Autism Foundation. Every Child is Born an Inventor On January 17, Inventor Children’s Day, we met with primary school students in Batman at the “Virtual Science Workshop” event in cooperation with the Bilim Kahramanları Association. We brought together little inventors who are curious, researching, questioning, looking for solutions to the problems of the 21st century, and interested in science, and created a series of workshops with different contents, showing that science activities can be done with simple materials. Self-Confidence Workshops and Coding Trainings With the motto “Self-confident children enrich the whole world,” we believe that self-confident girls who benefit equally from educational opportunities, participate actively in social life, and have self-confidence can revolutionize societies. As Hepsiburada, we organized a “Self-Confidence Workshop” in cooperation with the Yarına Umut Ol Association on International Day of the Girls. Simultaneously, we started a 2-month-long “Artificial Intelligence and Coding Training” to ensure that all children can access education and development opportunities.

The workshop continued with young girls exploring the bonds of imagination and creativity and ended with an inspiring webinar with Ece Gözen, eco-entrepreneur and founder of Gozen Institute. Eco-Friendly Tote Bags Meet Our Customers The negative consequences of plastic bag use are increasing day by day. According to the latest estimates, there are more than 150 million tons of plastic in the seas. Unless the current trajectory changes, by 2025 the seas will host 1 ton of plastic for every 3 tons of fish. There will be more plastic than fish in the seas in 2050.18 Taking action against this situation is no longer a choice but a necessity. For this reason, Türkiye’s Hepsiburada supported the Zero Waste Project implemented by the Turkish Ministry of Environment, Urbanization and Climate Change and brought thousands of recyclable, eco-friendly cloth tote bags specially produced for World Environment Day on June 5 to our customers. In order to reduce the use of plastic bags, we aimed to encourage the use of environmentally friendly products and raise awareness on this issue by adding thousands of tote bags made of raw cloth to the baskets of our customers who placed orders on June 5, Environment Day. 18 Ellen MacArthur Foundation and New Plastic Economy, 2017, The new plastics economy: rethinking the future of plastics & catalysing action. Hepsiburada Grove in Sivas We know that we need plant trees more than ever before as the pressure we put on nature with what we eat grows by the day. Therefore, in collaboration with ÇEKÜL (Foundation for the Protection and Promotion of Environmental and Cultural Values), we planted thousands of saplings and established the “Hepsiburada Grove” in Sivas to raise awareness and make a meaningful contribution to nature during the March 21-26 Forest Week.

TECHNOLOGY EMPOWERMENT FOR WOMEN ENTREPRENEURS Our “Technology Empowerment for Women Entrepreneurs” programme, launched in 2017, promotes women entrepreneurs in 81 provinces of Türkiye to participate in business life and enables them to participate in the digital economy through trainings and opportunities on our platform. We assist women who wish to start their own business and thrive in the e-commerce sector to take use of Hepsiburada’s technology and marketing capabilities. We have supported more than 41 thousand women entrepreneurs under the program. WOMEN ENTREPRENEURS OVERCOME FINANCIAL BARRIERS We also work on projects to financially help women entrepreneurs and build relationships with banks. Through agreements with multiple banks, we enable women entrepreneurs access attractive solutions with low commission rates to meet their financial needs more readily as part of our “Women Entrepreneurs Overcome Financial Barriers” project. We proudly assisted 146 women’s cooperatives through this initiative. Furthermore, in order to assist women entrepreneurs in their transition to the commercial world, we provide TEB Family Academy’s financial literacy training, which consists of five courses, to women entrepreneurs who use our platform. With our Women Entrepreneurs Overcome Financial Barriers project, women entrepreneurs utilized a total of TL 10.5 million in loans by taking advantage of the financial advantages we provide. STRONG WOMEN IN THE DIGITAL AGE PROJECT We launched the “Strong Women in the Digital Age Project” in October 2022 in collaboration with Innovation 4 Development (I4D) under the auspices of the US Embassy Grant Program. This initiative enables 22 women’s cooperatives and women entrepreneurs operating in Türkiye, some of whom include refugees among their members, to digitize and connect with customers via the Hepsiburada platform. As part of this initiative, which focuses on the role of entrepreneurship in economic empowerment of women, we provide 30 hours of thorough training and 250 hours of mentoring support to 22 women’s cooperatives and 250 women entrepreneurs. In addition, we offer Hepsiburada supports designed for women entrepreneurs as well as an additional support package tailored to the specific project (such as indefinite commission discount, indefinite free shipping service, free photo shoot of 500 products, advertising and design support). WE SUPPORT WOMEN’S COOPERATIVES In order to make their products available in all 81 of Türkiye’s provinces and to connect them with more clients, we help women’s cooperatives throughout the country in order to promote rural development and the revival of the women’s economy in underprivileged communities. We facilitate access to natural and local products by combining the power of labor with the power of technology. Currently, more than 220 women’s cooperatives are selling on the Hepsiburada platform, and we are working to increase this number every day. We also support women’s cooperatives with the following advantages: • Indefinite commission discount of 75% in selected categories, • Free photo shoot for up to 500 products, • Free display in campaign areas, • Indefinite and free shipping, • 2 advertising banners worth TL 30,000, • Technology Empowerment for Women Entrepreneurs Power e-commerce training, • Support for integrator company payments in stock and price integration, • TL 500 gift voucher for sponsored product advertisements Women’s Entrepreneurship Women’s Cooperatives GRI 3-3, GRI 413-1, GRI 203-1 Women’s Cooperatives Benefits

In addition, when imported products are substituted with local products, the negative environmental impact of transport over long distances is reduced and the resilience of ecosystems is increased. Increased self-sufficiency, preservation of traditional cultures and community empowerment also represent positive social impacts of this substitution. As a result, we believe that supporting local growth through e-commerce is one of the most significant building blocks of our strategy of growing and developing with our stakeholders, which is part of our corporate culture at Hepsiburada. In this regard, we continue to develop new projects that will help businesses and the national economy grow faster. In cooperation with The Union of Chambers and Commodity Exchanges of Turkey, the HepsiTürkiye’den Local Products Program was launched in 2021. We continue to support SMEs, women entrepreneurs, and cooperatives that produce locally and regionally by promoting their goods online and assisting them in growing their e-commerce presence. We offer products that are registered as geographically indicated for sale on our platform as part of the HepsiTürkiye’den program, and we make them stand out in terms of tradition and quality. We provide producers with excellent marketing and branding support in a variety of areas, including commission, promotion, training, shipping, and call center. We provide e-commerce opportunities to the producers of local products who are new to e-commerce and offer them access to the national market with our strong marketing and branding support. By promoting greater awareness of professions and arts with traditional, cultural, or artistic value that are on the verge of extinction, we both pave the way for the preservation of our national treasures, traditional, cultural, and artistic values for future generations, and contribute to the national economy by revitalizing the local economy. In 2022, as part of the HepsiTürkiye’den program, we collaborated with the Turkish Patent and Trademark Office on the development of “Geographically Indicated Products” through the e-commerce sector. “Geographically Indicated Products” refers to the legal protection of traditional products made with local raw materials, and we hope to promote these products through e-commerce by making them available to a large number of consumers in Türkiye and around the world. At the same time, we aim to raise awareness of geographically indicated products and to promote national assets by providing informative training on the rights and obligations of both producers and consumers.

We expect all Hepsiburada employees, regardless of their position, to exhibit attitudes and behaviors that will ensure the cultural integrity of the company. We have enhanced Hepsiburada’s Code of Ethics, which we have already shared with our stakeholders, by including the requirements arising from being publicly traded in the United States, and we have altered our training content accordingly. Subsequently, we ensured that all our stakeholders received our updated trainings again. At Hepsiburada, it is one of our top priorities that our ethical way of doing business is embraced by all our colleagues. Accordingly, within the scope of Hepsinstitute, there are mandatory trainings on our Code of Ethics for our newly recruited colleagues. In 2022, we provided 5600hours of Code of Ethics training to our colleagues. Furthermore, we share information on and remind our Code of Ethics to all internal stakeholders through the in-house applications. We have an Ethics Board within Hepsiburada. Every three months, the Corporate Governance Committee, a subcommittee of the Board of Directors, receives a report from the Ethics Board outlining the steps it has taken in compliance with the Disciplinary Regulation. We also have an effectively functioning Ethics and Compliance program. We have implemented the policies and procedures that we are required to fully comply with as part of the program and have published them on internal online platforms. Furthermore, in order to raise awareness, we have developed a mandatory training program that employees should participate as part of their orientation at the time of recruitment, which is also refreshed annually. Within this training program, in addition to Ethics and Compliance issues, fair competition was also addressed. Further to the written training documentation, we periodically train our employees every year by a Competition Law consultant focusing on interactive questions and problems related to the sector.

The lack of access to COVID-19 solutions and the resulting uneven economic recovery risked exacerbating social fractures and geopolitical tensions. By 2024, developing economies (excluding China) are expected to be 5.5% behind pre-pandemic GDP growth, while advanced economies would have outpaced it by 0.9%, expanding the global income disparity. The results of the Global Risks Perception Survey included in the 2022 Global Risks Report, shows that over the next three years, companies are expected to be characterized by either consistent volatility and multiple surprises or fractured trajectories that will separate relative winners and losers. However, concerns are growing about the state of our world 10 years into the future. Environmental risks pose the five most critical long-term threats to the world through “climate action”. They are also seen as the potential threat that could do the most harm to people and the planet. As Hepsiburada embarks on its sustainability path, we share common concerns with the rest of the globe and we believe that we cannot consider economy only in terms of sales and profits any more. We acknowledge the importance of addressing all parts of strategies developed across environmental, social, and economic concerns, and we know that organizations lacking this collective view will struggle to capitalize on economic opportunities in the near future. Under current conditions, the private sector and businesses must produce value for all stakeholders with whom they interact in economic, environmental, and social dimensions by creating jobs, investing in the economy’s productive potential, and serving society. Therefore, with our motto “Transformation for a Sustainable Future Starts Here” and our holistic perspective, we aim to position ourselves as the leading company in Türkiye and in our sector. With our Hepsiburada platform, visited by more than 12 million million visitors daily and 370 million monthly, our brands—each of which, thanks to the investments we have made, brings an innovative perspective to its field—3,806 employees, more than 99 thousand active merchants, more than 5,000 suppliers, and the thousands of women entrepreneurs and cooperatives we support, we add value for the national economy and all of our stakeholders. 20 The Global Risks Report 2022.

Accordingly, we aim to increase the economic value we create together with our stakeholders. After our merchants open their virtual stores on our platform, we work with them every step of the way and develop this structure together with our entire value chain. We aim to partner with our merchants to give them the tools and training they need to start and grow their business on our platform. With our support, advocacy, and the advantages we provide, we enable entrepreneurs, corporations, and non-profit organizations of all sizes to create their brands on the Hepsiburada platform in line with their product inventory. More than 150 thousand SMEs and other businesses in Türkiye chose Hepsiburada to start e-commerce, introduce their products to millions of customers in Türkiye and throughout the world, and profit from rapid, high quality, secure, and high standards of e-commerce, and we launched the Hepsiburada Business Partner project with the aim of further expanding this big family we have created with our merchants and business partners. We provide our merchants with access to a privileged world through the Hepsiburada Business Partner application, which will alleviate a variety of operational and financial burdens. Thanks to our project, we came together with more than 1,000 merchants. By sharing Hepsiburada’s digital and innovative know-how with our merchants, we came closer to our goal of growing together As part of the Hepsiburada Business Partner project, we supported our merchants in meetings held in our Ankara, Izmir, and Istanbul offices by implementing the following projects in line with our innovative and transformational vision: • We introduced the merchants, the Auto Hunt Project, which makes an automatic offer & commission recommendation for potential products with a smart algorithm. • We launched the Merchant-Proposed Quotation Project, which enables the merchants to propose commission and prices to Hepsiburada category teams for their products. • With Hepsiglobal, we have enabled our merchants to sell in multiple countries and expand their products abroad. We offer our partners the opportunity to develop their business by strengthening their knowledge and capabilities about products, orders, advertising management and campaigns. Because we believe at Hepsiburada that we grow along with our stakeholders, and with all of these creative applications, we can say to our business partners, “Here is your digital power to build your business!” Our drive to create economic opportunity for all extends beyond the marketplace to the communities in which we live and work. Nonprofit organizations and charities use our platform every day to help fund their vital work within communities. At the same time, in order to promote the local economy, we continue to support entrepreneurs, who have historically required more representation. GRI 201-1, GRI 203-2

In this regard, we acknowledge that it is our duty to ensure that all businesses operating within our ecosystem abide by the business ethics and principles, policies, and rules, and that our suppliers, contractors, and all other business partners with whom we have the privilege of doing business also uphold the applicable laws and the guiding principles outlined in the “Hepsiburada Third Parties Business Ethics and Compliance Declaration.” This declaration, based on international standards and all applicable legislation and regulations, particularly the International Labor Organization (ILO) and United Nations (UN) Conventions, establishes the Supplier Code of Conduct (occupational health and safety, non-discrimination, working conditions, prevention of child labor and forced labor, right to collective bargaining, environment, and abuse prevention) that our suppliers must follow. We have a “Supplier Management Procedure” in which we assess our current and prospective suppliers from the commencement of the work through its completion. This procedure helps us to manage all our processes from potential supplier assessment to contracting, from risk assessment and security measures to current supplier analysis, based on our third party business ethics and compliance declaration.

The costs associated with handling a data breach can take a direct and significant toll on company reputation, customer loyalty and company resources. The social impact of cybersecurity attacks includes privacy breaches, threats to personal security and disruption to access to the necessities of life. Privacy is increasingly recognized as a human right and various regulations are in place around the world to protect it. As companies digitize and business models shift towards complex, data-driven products and services, issues around data security and privacy are becoming significant drivers of business risk. Sectors that involve the widespread collection and use of personal data mean that companies in a wide range of sub-sectors are exposed to the cumulative risk of data privacy and security risk.21 Ensuring data security and privacy is one of Hepsiburada’s highest governance priorities. As a result, we will keep working to protect, manage, and enhance the personal information of our customers, as well as our information assets, which include the hardware and software that make up our information systems and other components of our data security. We believe that data protection and data privacy are the foundation of a sustainable digital economy and a reliable service ecosystem. As Hepsiburada, we strengthen our commitment to privacy by ensuring that our customers feel safe while using our services by saying Ethical and Transparent Business Understanding Starts Here. According to PricewaterhouseCoopers’ (PwC) 2023 Global Digital Trust Survey, more than 70% of technology and security executives (CEOs, Directors, CFOs, CISOs, CIOs, and other C-levels) of 3,522 respondent businesses observed improvements in cybersecurity in the past year thanks to investments and C-level and senior management collaboration. More than a quarter (26%) reported progress in all 10 areas identified as critical for cyber maturity.22 On the Hepsiburada platform, millions of transactions take place every day. We value the trust that merchants and buyers place in Hepsiburada by protecting all personal information, and we prioritize compliance with privacy principles. We are committed to maintaining a globally recognized privacy and information protection policy in line with international best practices and standards, including the ISO 27001 Information Security Management System Standard. As Hepsiburada, we are committed to the following issues in order to ensure the confidentiality, integrity, and accessibility of information, in accordance with the organization’s mission and vision, and within the framework of the TS ISO/IEC 27001 Information Security Management System (ISMS) standard; • We plan, implement, and regulate our actions according to this standard by setting information security targets and activities, ensuring continuous system improvement. • We define how the activities carried out meet regulatory, contractual, standard and business requirements. • We describe how we meet the requirements of the Personal Data Protection Law (PDPL). • We carry out ISMS activities in an integrated manner with other management systems installed within our organization. • We determine the duties, roles and responsibilities and the necessary resources as part of the ISMS. • We create an inventory of information assets by determining the criteria of confidentiality, integrity and accessibility. • To manage information security, we identify and assess existing and potential risks and put in place appropriate risk handling options. • We make business continuity plans, implement these plans and ensure continuous improvement of the process. • We follow current technologies and innovations in information 21 Data Privacy, Cybersecurity and ESG: Managing Risks in a Changing Business Environment.

This procedure details our efforts to identify risks, the processes affected by these risks and the related internal and external parties, the affected assets and their locations, the likelihood of the risks, their impact on confidentiality, integrity and availability, the value of assets, the likelihood of threats that could have a business impact, the ease with which identified threats can be exploited by vulnerabilities, and any existing or planned controls that can mitigate the risks. We address our information security risks under the Confidentiality, Integrity and Accessibility subcategories in terms of their potential impact. According to the risk score in the resulting assessment matrix, we manage our risks through risk mitigation, risk transfer, risk acceptance and risk avoidance.

There are numerous ways and techniques through which governments and markets can interact with one another to foster innovation that can lead to new favorable short- and long-term outcomes, according to examples of best practices from around the world. Research shows that while various technologies have driven innovation growth over the last 100 years, patents for digital-related innovations have grown 172% faster than all patents over the last five years. Intellectual property not only helps shape the future, but also has the potential to be a good shortcut to achieve our global sustainability goals in terms of environment, social and governance when used correctly. When innovation comes together with sustainability, it can become a domino effect. Accordingly, we believe that the protection of intellectual property rights is one of the key elements of operating a healthy and sustainable e-commerce system. Recognizing the importance of trust in the Hepsiburada ecosystem, we consider consumer and merchant trust in our platform to be one of our most significant business goals. We are carrying out a number of coordinated initiatives to assure the sale of branded, authorized items and to dissuade the sale of unlawful or unauthorized products in order to protect the interests of rights holders, brands, and consumers. With our agile and solution-oriented approach, we aim to identify problems early before receiving complaints related to violations of intellectual property rights. We are aware that protecting intellectual property rights is a priority closely related to governance for a digital and online service ecosystem. We manage this risk with the various measures we take and properly designed information security policies, and we continuously advance our efforts to uphold confidence in the evolving and changing digital environment. We are aware of the advantages of collaborations with intellectual property owners, both in terms of minimizing the risks and turning them into opportunities. Therefore, we consider it inevitable to include our stakeholders in our efforts to achieve short-medium-long term goals. 23 World Intellectual Property Report 2022: The Direction of Innovation.
