3 2023 SUSTAINABILITY REPORT AND PUBLIC ACCOUNTABILITY STATEMENT

To be the best full-service bank for business owners in Canada, our approach to sustainability ensures we will continue to deliver on this commitment in an increasingly complex world. The economic backdrop was challenged last year through monetary policy actions to curb persistent inflation while Canadians also faced significant wildfires during the warmest summer on record. We deeply understand the businesses of our clients and the evolving risks they face, and that’s why our clients continue to choose us as a trusted advisor and their banking provider. We are committed to managing our approach to sustainability to focus on the areas that are most important to our clients, people, investors and communities, guided by our values, culture and strategy. Our 2023 Sustainability Report highlights our progress against this commitment. We maintain a foundation of trust under the stewardship of our diverse and experienced Board of Directors whose mandate includes our strategy, risk appetite and culture. In 2023 the Board continued to oversee our climate strategy, approach to social matters and governance structure, and reviewed our sustainability report and key ESG initiatives. Our ESG Steering Committee provided leadership and oversight of the design and execution of our approach to sustainability, ensuring intentional focus on our strategy. We are obsessed with the success of our clients and strive to deliver an unrivaled client experience with a focus on personalized and differentiated advice, and efficient and convenient transactional processing through our enhanced digital platforms. In 2023 we migrated our retail and small business clients to cwb.digital TM , along with continued enhancements to functionality. We maintain an accessible and inclusive environment where our clients with diverse needs and backgrounds see CWB as a great place to bank, and continued to expand our wealth management relationships with Indigenous communities. We are committed to building on our inclusive culture and creating opportunities and growth for our team members in an organization where skill and performance is recognized, rewarded, and celebrated. Our 11 Employee Represented Groups (ERGs) continued to provide a sense of belonging to equity-seeking groups who are often impacted by systemic Message from the President and Chief Executive Officer

barriers, with over one-third of our people belonging to at least one ERG. Our values and culture inspire our teams to continue to go above and beyond for our clients in challenging environments by rapidly adapting to changing conditions. I am proud of our team’s achievements as we were recognized as one of the Best Workplaces TM in Canada for the fourth consecutive year and placed in the top 25 for the second year in a row. We were also recognized by Waterstone Human Capital as having one of Canada’s Most Admired Corporate Cultures TM for the fourth time, earning a place in their hall of fame. We recognize that we have a part to play in Canada’s transition to net-zero emissions by managing our direct and indirect climate impact, and in 2023 we took decisive steps towards this goal. We developed an absolute Scope 1 and 2 GHG emissions reduction target of 42% by 2030, leveraging the guidance provided by the Science-Based Targets initiative (SBTi). We also disclosed initial estimates of Scope 3 financed emissions related to our residential mortgages and oil and gas extraction lending portfolios, and intend to expand the scope of our disclosures in future years. We also developed a climate risk heat map as an initial step to increase our understanding of the impact of physical and transition risks to key industries within our loan portfolio. I am proud of our progress this year, and confident in our ability to drive responsible, sustainable growth as we navigate the evolving landscape in front of us. I would like to express my gratitude to our clients for the opportunity to be a trusted partner in their success, and our team members for the care, dedication and integrity they have demonstrated in a challenging environment. Through their efforts we have built a strong, resilient full-service bank and are well positioned to create value for all our stakeholders going forward.

ABOUT OUR BOARD OF DIRECTORS

With current director nominees, if elected, 56% (1) of the Board will be comprised of women, surpassing the targets for women in both our Corporate Governance policy (target of 40%) and the 30% Club. Further, 11% (1) of Board directors identify as Black, Indigenous or racialized persons, surpassing the targets in our Corporate Governance policy (target of 5%) and our BlackNorth CEO Pledge commitment, well in advance of the 2025 deadline.

Our Board’s primary responsibilities include oversight of CWB’s risk appetite, culture, strategy, capital plans and key policies, and to provide challenge, advice and guidance to senior management. To fulfill its mandate, certain responsibilities are delegated to its standing committees, which include the Audit, Governance and Conduct Review (GCR), Human Resources (HR), and Risk Committees (collectively, the Committees). Effective Board composition Our Board is composed of independent directors and our Chief Executive Officer (CEO), who have diverse backgrounds and complementary experience and expertise to ensure robust oversight. During director recruitment and succession planning, the GCR Committee seeks out suitable candidates and assesses the potential candidate’s experience and expertise against the needs of the Board and its Committees. The GCR Committee uses an expertise and skills matrix to assess our directors and regularly analyzes whether the Board has the appropriate composition. Board diversity commitments On behalf of CWB, the Chair of the Board and the President and CEO have signed on as members of the 30% Club Canada, an organization that supports the goal of having 30% of corporate board positions held by women. In 2020, the President and CEO signed the BlackNorth CEO Pledge, committing CWB to specific actions and targets designed to end anti-Black systemic racism.

(1) Refer to our most recent Management Proxy Circular for more information on the election process.

Strong governance practices Our Board works closely with management to ensure our governance approach incorporates evolving industry trends, regulatory expectations and global best practices. We ensure our governance policies meet or exceed the requirements of our regulators. We consider, and where appropriate adopt, new corporate governance best practices put forward by governance institutions, industry groups, and groups that represent the interests of our shareholders and other stakeholders.

Refer to our most recent Management Proxy Circular for more information about our approach to corporate governance. Formal mandates for the Board and its Committees can be found on our website at: www.cwb.com/corporate-governance .

Our Board continues to provide strong governance of CWB’s business and our winning strategy to be the best full-service bank for business owners in Canada. We provide close oversight of CWB’s risk appetite and risk management framework and remain focused on CWB’s evolving approach to address social and environmental risk, including climate risk. CWB continues to prioritize the ongoing success of our clients and remains committed to long-term value creation for all stakeholders and sustainable growth of our business. We are proud of the progress we have made to-date and are committed to support and engage with management as they continue to develop and implement CWB’s approach to sustainability.”

Overview

FOSTERING A SAFE ENVIRONMENT TO RAISE CONCERNS

Our ethics program provides avenues for our team members, contingent workers, and third parties to raise serious ethical questions and concerns through multiple levels of intervention, including confidential interaction with our embedded Ethics Officers or an anonymous Ethics Hotline, which is managed by a third-party provider. We protect individuals who raise ethical concerns and prohibit retaliation against a person for reporting in good faith an issue or participating in an investigation as this is a serious violation of our Code of Conduct. A summary report of all concerns raised or identified is provided to the Ethics Committee and the GCR Committee on a quarterly basis.

TRAINING AND AWARENESS

Training is a crucial element of our ethics-based culture as it provides our team members with the knowledge required to understand their responsibilities to act with integrity and in compliance with regulatory requirements. Our ethics program sets out mandatory training requirements for our team members and periodically highlights ethics-related topics and practices to the broader organization. These training requirements address a wide range of topics, including anti-money laundering and anti-terrorist financing, ethics awareness, fraud awareness, operational risk management, economic sanctions laws, workplace harassment and violence prevention, material non-public information and insider training.

(1) Active employees are defined as full-time and part-time employees as at February 24, 2024.

EMBEDDING ETHICAL BEHAVIOUR WITHIN COMPENSATION Team member performance management and compensation are directly aligned to ethical decision- making and risk management. A significant portion of every team member’s performance rating is based on performance drivers, which include acting with integrity and in line with our values. If an individual engages in job-related fraud, ethical misconduct, or a serious violation of CWB policies, our internal Human Resources (HR) function or the HR Committee of the Board may exercise its discretion to recommend disciplinary actions. For individuals at mid-level management roles or above who participate in the LTIP, actions may include recoupment of previously paid variable cash compensation, forfeiture of vested and unvested equity-based variable compensation or recoupment of any realized gains on previously exercised equity-based compensation.

17 2023 SUSTAINABILITY REPORT AND PUBLIC ACCOUNTABILITY STATEMENT

Human rights

Protecting human rights is crucial to building a more equitable, inclusive and sustainable society. In alignment with our culture and values, we support and respect the protection of human rights throughout our operations and across our business.

AN INTEGRATED APPROACH

To support awareness of commitments and responsibilities, our team members are required to complete training on human rights topics, including workplace harassment and violence prevention and our accessibility program, upon hire and on a regular basis thereafter. Our Ethics program provides multiple avenues for our team members and contractors to raise human rights questions and concerns, including confidential interaction with our embedded Ethics Officers and an anonymous Ethics Hotline.

We operate solely in Canada and comply with all federal, provincial and territorial human rights laws and standards, including the Canadian Human Rights Act and the Canada Labour Code. – Code of Conduct: We are guided by our values and Code of Conduct to promote an inclusive and safe work environment that is free of discrimination and harassment based on race, colour, ancestry, national or ethnic origin, pardoned criminal conviction, religious beliefs, gender, age, disability, marital status, family status, source of income, gender identity or expression, genetic characteristics or sexual orientation. – Recruitment and talent management practices: We are an equitable employer and follow a merit-based approach in all areas of employment, including recruitment, hiring, career advancement, and access to benefits and opportunities. – Accessibility program: Under our Accessibility program, we strive to create an environment where all our team members and clients have access to the support and resources they need to succeed. This includes tailored communication strategies, barrier-free access at our locations, and individualized accommodation plans to remove barriers that may affect our team members’ performance or access to training and development opportunities. – Supplier Code of Conduct: In 2023, we finalized the development of our Supplier Code of Conduct and communicated the content to our suppliers.

Overview

DATA PRIVACY Our approach Our comprehensive Privacy Compliance framework establishes the principles of our organization-wide privacy management program to protect the personal information of our clients and comply with applicable legal and regulatory requirements. Our Chief Privacy Officer oversees our privacy management program and is responsible to set and monitor the effectiveness of related policies and procedures. The Governance and Conduct Review (GCR) Committee of the Board oversees privacy risk management and receives regular reporting as part of its oversight responsibilities. Incidents involving suspected or actual breaches of privacy are documented and investigated by our Privacy Office. If a privacy breach has occurred, our teams follow established procedures to limit its impact, understand the root cause of the incident, ensure that the issue is remediated and take preventative steps to avoid recurrence. Where appropriate, we notify applicable regulators and impacted individuals.

Our privacy management program extends to third-party service providers, and we assess their privacy management practices and controls prior to providing them with any personal information of our clients. Once satisfied with the service provider’s procedures and safeguards, we will only provide them with the personal information required to deliver contracted services. Training and awareness We make privacy a key focus for our team members and take steps to ensure they are aware of privacy-related regulatory obligations relevant to their role, know how to comply with those obligations, and are accountable to achieve effective compliance. All team members are required to undergo privacy training as part of their onboarding experience, and on an annual basis thereafter. Privacy principles, such as only accessing information for legitimate business purposes, are also embedded in our Code of Conduct, which applies to all our directors, officers and team members.

Refer to our Privacy Statement and Online Privacy and Interest-Based Advertising Statement to learn more about our privacy management practices, including an overview of how we collect, use and disclose personal information, and the choices clients may exercise in this regard.

CYBERSECURITY Our approach

evaluate key performance indicators and metrics, such as incident response times and threat resolution effectiveness. These measures are crucial for understanding our program’s contribution to the organization’s resilience. Our program is managed by a team of technical and cybersecurity professionals dedicated to proactive identification, containment, and eradication of cybersecurity threats. We have a comprehensive control framework that is continually assessed for effectiveness using well-established threat intelligence and risk management programs. Innovation is at the heart of our cybersecurity strategy. We leverage AI-driven threat detection systems and invest in technologies that not only enhance security but also align with our environmental commitments. The CISO has a dedicated Security Operations Centre (SOC) responsible for the management of cyber incident handling, detection, response and recovery. This specialized team executes on containment strategies and recovery support in the event of a cybersecurity incident in accordance with CWB’s protocols. We proactively conduct regular threat analysis activities to identify vulnerabilities in technology and operational processes, and opportunities for remediation. Vulnerabilities are assessed across all technologies and services, and we have defined timeframes around remediation, based on the criticality of the affected service and impact or likelihood of exploitation. We maintain insurance coverage to help mitigate against certain potential losses associated with cyber incidents. Recognizing the importance of the entire supply chain to our security posture, we have a mature third-party security risk management program. This program assesses the cybersecurity practices of our vendors, ensuring they uphold the required standards.

Our cybersecurity program is a mature practice, influenced by well-recognized industry security frameworks. Guided by the National Institute of Standards and Technology (NIST) framework and aligned to industry standards like COBIT 5 and ISO/IEC 27001, we manage information security with precision and foresight. These frameworks not only bolster our defenses but also echo our dedication to responsible information technology governance and management. Our cybersecurity governance is robust, with the Chief Information Security Officer (CISO) at the helm, reporting to the Chief Information Officer, and ultimately to our Board of Directors. This governance structure ensures accountability and strategic alignment with our sustainability goals. Our Board provides oversight and receives quarterly reports, which include updates on the ongoing maturation of our program and our proactive measures for risk management. Within our three lines of defence model, our Information Security team is responsible for execution of our cybersecurity risk management program, with second and third-line oversight provided by the Risk Management and Internal Audit teams. Our Board of Directors provides oversight of our cybersecurity risk management program and receives quarterly reporting on key activities and the ongoing maturation of our program. We are committed to continuous advancement in our cybersecurity efforts. By regularly updating our practices and investing in the currency of our technology, we enhance our ability to respond to emerging threats. To demonstrate the impact of our cybersecurity initiatives, we regularly

Training and awareness Our cybersecurity training program is transparent and inclusive, engaging with the community and stakeholders to foster a shared culture of security. We conduct employee training and public awareness initiatives that emphasize the importance of cybersecurity in achieving sustainable development goals. The program includes mandatory monthly employee training requirements, with shifting areas of focus based on current and emerging threats, and simulation tests to assess the effectiveness of our training programs. Areas within the organization that require more focused training are assessed on a regular basis to ensure our team members within higher-risk job functions understand their responsibilities to protect our systems and information. Each October, we also complete an organization-wide cybersecurity awareness campaign in association with National Cybersecurity Awareness month.

In 2023 our “Step up your cyber fitness” Cybersecurity Awareness Month campaign featured: • A webinar on the most common cyber threats and tools for online safety; • Articles on how to avoid social engineering scams and why Multifactor Authentication is an essential cybersecurity defence tool; • Resources and a quiz on cyber fitness.
