A Message From Comerica's CEO, Being a Responsible Company

Read the full 2018 Comerica Corporate Responsibility Report

Being a responsible company is a fundamental part of Comerica's culture. Our 170-year history is grounded in a relationship-based approach to helping people and businesses be successful. Living out our Core Values and our commitment to corporate responsibility means we remain firmly rooted in serving as a valued and trusted advisor to our clients while delivering attractive returns for our shareholders and supporting the communities which we serve.

We continue to support our strong culture of diversity and inclusion, community involvement, and environmental commitment, as detailed throughout this report. In addition, in 2018, we remained committed to expanding our product offerings and investing in technology, including the advancement of our TechVision 2020 to securely deliver customer-centric products and services with speed and agility. Combined, these efforts bolstered our financial performance in 2018, with all-time-high revenues and earnings per share, improved efficiency ratio, strong credit quality and exceptional shareholder value.

Our efforts in the area of corporate responsibility have been noticed by many prestigious organizations and we are very proud of the recognition we have received in 2018. Examples are shown on the following page and include listings for best companies for diversity, most civic-minded companies, and most sustainable companies to name just a few.

Our Corporate Responsibility Report provides numerous performance metrics. But these metrics only tell a small part of our story. While providing a comprehensive look at our environmental, social and governance (ESG) practices in accordance with the Global Reporting Initiative (GRI) Standards, we have included examples that illustrate the depth and breadth of our corporate responsibility commitment.

In addition, we continue to map how our corporate responsibility efforts reflect the United Nations' 17 Sustainable Development Goals (SDGs). From addressing inequalities to supporting sustainable cities and communities, we play our part in tending to our planet's and society's greatest needs. For more on our reporting methodology, terminology and standards, please see the Reporting Methodology section of this report.

As we reflect on 2018, we are pleased with the work we have done and the progress we have made, and we acknowledge our challenges and opportunities. Our thanks to all of you who have helped us along the way. We eagerly anticipate progress towards a thriving future.

Sincerely,

Curtis C. Farmer

President and Chief Executive Officer
