We continued to execute against our focused growth plan: Powerful Organic Growth New Growth Opportunities Strong Financial Performance PAGE 14 INNERWORKINGS / 2012 ANNUAL REPORT dRIVE ORGANIC GROWTH Our Enterprise business is a powerful organic growth engine and the foundation of the company. In 2012, we recorded over $100 million of organic revenue from new clients. And we signed three of the largest new enterprise contracts in our history. Our client retention rate is outstanding, which demonstrates the ongoing innovation and value we deliver for our clients. We now have flagship clients serving as references in most major industries, and our pipeline for new enterprise business is stronger than ever. This past year, we made investments to fuel our global enterprise growth. First, we entered Brazil and China, which strengthens our global platform and our ability to serve clients on multiple continents. Second, we’ve invested in the development of our next-generation technology platform, which handles all currencies and languages, and will allow for seamless collaboration of client concepts and reporting across our clients’ regions. Lastly, we added talented new leadership in Europe, Asia and Latin America. Today, we have employees in 33 countries and are providing services for clients in 169 countries. We believe the future of the industry is a global solution and we intend to be the preeminent provider. dEVELOP NEW GROWTH OPPORTUNITIES We continue to develop new ways to expand our sales and product capabilities. The Inside Sales initiative that we launched in 2010 to serve small and medium-sized businesses saw revenues more than double in 2012. We believe this solution represents the way of the future for this market segment, and stands as yet another example of InnerWorkings blazing the trail in our industry. We’ve also added important service capabilities in the past year. For example, we now offer a comprehensive internal creative studio service for Fortune 500 companies. This aligns with our vision of becoming an end-to-end marketing supply chain provider. We will continue to evaluate and deploy new product and service offerings through both internal development and acquisition strategies. ACHIEVE STRONG FINANCIAL PERFORMANCE I am proud of what we accomplished in 2012. Our revenues grew 26% to $798 million, with the majority of the growth being organic in nature. Operating income also expanded 26% to $28 million. And our return on invested capital grew while we reduced our debt. Importantly, none of these improved metrics were realized at the expense of our future opportu- nities as we made meaningful investments in our future throughout the year. We expect these resource allocation decisions to drive stockholder returns in the future. Our talented employees—including the hundreds onsite with our clients—remain focused on delivering value to our clients. We are committed to becoming a global powerhouse with the most respected name in the industry. 2012 was a tremendous year, but we’re just getting started. We have a huge market opportunity in front of us, and we intend to capitalize on it. On behalf of everyone at InnerWorkings, I’d like to thank you for your continued support.
