Roth, Interpublic’s Chairman and CEO. “Our commitment to incubating new skills, developing new products and services, and investing in new technology has allowed us to stay highly relevant in today’s digital world. This gives us confidence that our offerings will remain vital to marketers as they seek to navigate the increasingly complex consumer and media landscape. Our focus on our best-in-class offerings and continued cost discipline, combined with our company’s financial strength and robust capital return programs, will continue to be a source of significant value creation. In light of the very strong performance to date through the third quarter, we believe we are on track to exceed 5% organic revenue growth for 2015, above our previous target of 4-5%, and that we are well-positioned to deliver 100 basis points of operating margin improvement, the high end of our targeted range. As always, our focus will be on the caliber of our people, the success of our clients and on further enhancing shareholder value.”
