Philippe Krakowsky, CEO of IPG:
“Second quarter performance was solid, with moderate acceleration in organic growth, as well as margin expansion compared to the same period last year. Consistent with our longer-term performance, IPG Mediabrands and IPG Health led the way in the quarter. We also saw notable contributions to growth from Deutsch LA, Golin and Acxiom. Creatively, our agencies continued to garner exceptional levels of recognition for the quality of their ideas and innovation, across all marketing disciplines.
“The most successful businesses in our portfolio continue to demonstrate specialized, high-value services that identify and reach audiences with greater precision and accountability, in turn leading to growth in our clients’ brands and businesses. Much of this work is powered by our industry-leading audience data and a technology stack that unifies the marketing funnel. This enables marketers to assess and understand the value of their investments, whether on technology platforms, in earned and paid media, or in other key sales and retail channels. We continue to focus on these growth areas of the business, as well as on integrating generative AI tools and technologies into our content and creative offerings.
“Given results in the year to date, trends within our client roster, and macro sentiment, we expect to achieve full-year organic growth of approximately 1% and, at that level of growth, continue to target adjusted EBITA margin of 16.6%. Additional areas for value creation include our strong balance sheet and liquidity, as well as our ongoing commitment to capital returns.”
