The year included a few challenges that impacted our results, yet we still delivered double-digit revenue growth, setting the company up nicely for strong future performance. D R I V I N G N E W G R O W T H Our core enterprise business continued to perform at a high level, winning nearly $80 million of new business during the year. In addition to welcoming an impressive roster of new clients, we expanded into new global markets with a number of our existing clients. As a result, our Latin America region generated over 50 percent of organic revenue growth, while our Europe and Middle East region realized nearly 20 percent. Our relatively new global platform is a true differentiator for us, and we expect it will create many more opportunities for shareholder value creation moving forward. During the year, we also meaningfully expanded our capabilities through the acquisi- tions of DB Studios and EYELEVEL. As a result, InnerWorkings is now one of the world’s leading providers of permanent brand display fixtures for the retail environment. This capability has already helped us win major new client agreements, and it will play an important role in both new and existing client growth strategies going forward. 2 0 1 3 A N N U A L R E P O R T / 1 6 We also re-engineered our approach to the middle market. After determining that our customer acquisition strategy could not be profitably scaled by relying primarily on an inside sales team, we entered into a strategic alliance with a Fortune 500 company that serves small and medium-sized companies through hundreds of retail locations across the United States. This new long-term contractual arrangement provides us access to a meaningful supply of new customers at the moment they’re seeking to make a purchase, and allows us to leverage our powerful technology platform, best-in-class pricing, and broad supplier network for small and medium-sized companies. Q U I C K A D J U S T M E N T S Alongside these great accomplishments, we encountered a few challenges during 2013. We lost the majority of spending from our then-largest customer last year, triggered by that company selling most of its assets to a private equity firm. This was an isolated event and, consistent with our company’s outstanding track record of client satisfaction and retention, we continue to serve the customer under the assets that weren’t part of the sale. We also were challenged by leadership and performance issues within Productions Graphics, the business headquartered in France that we acquired in 2011. We replaced management with new seasoned leaders and we are confident in our future throughout the European region, where we continue to expand with many of our multi- national clients. L O O K I N G A H E A D We enter 2014 with a lot of momentum. With a focus on execution of our core enterprise business, I expect us to have an excellent year and return to our pattern of delivering on our targets. We have outstanding new client prospects around the globe, we are rolling out our powerful new global technology platform, and we have the best talent in our industry. We continue to deliver breakthrough brand experiences for some of the world’s most well-known companies across formats, experiences and geographies. We expect to drive profitability and shareholder value as a result of these impactful capabilities. On behalf of all of us at InnerWorkings, I’d like to thank you for your continued support.
