Philippe Krakowsky, CEO of IPG:

“Third quarter performance was highlighted by solid revenue growth in all world regions, and driven by contributions from across our portfolio, whether viewed by segments, agencies or marketing disciplines. For the quarter, organic growth was 5.6%, on top of 15.0% a year ago, which brings our three-year growth stack to 16.9%.

“Embedding digital across the portfolio and adding a layer of data and tech to our offerings have been important parts of our playbook, as has our commitment to strong agency brands and industry-leading talent. Our people are delivering marketing and media solutions that bring together creativity, technology and data in ways that drive growth for our clients and as we look to the future, an important area of focus will continue to be commerce and business transformation work.

“Despite heightened macroeconomic and geopolitical uncertainty, we are upgrading our expectation for organic growth for the full year to 7%. With growth at that level, we expect to achieve adjusted EBITA margin of 16.6%. As we further evolve our offerings and align our portfolio in the service of clients, we see significant opportunity to keep creating value for all of our stakeholders.”

Operating Expenses

Total salaries and related expenses in the third quarter of 2022 were $1.55 billion, an increase of 2.4% from a year ago.

Total salaries and related expenses in the first nine months of 2022 were $4.70 billion, an increase 7.1% from a year ago. The increase was primarily due to an increase in base

salaries, benefits and payroll tax, which was driven by hiring to support revenue growth, partially offset by a decrease in performance-based employee compensation expense.

Selling, general and administrative expenses were $18.5 million in the third quarter, a decrease of 42.5% from a year ago, due to decreases in performance-based incentive compensation expense. Selling, general and administrative expenses were$57.2 million in the first nine months of 2022, a decrease of 36.3% from a year ago, due to decreases in performance-based incentive compensation expense.

Depreciation and amortization expense decreased by 3.5% during the third quarter of 2022, and decreased by 3.3% during the first nine months of 2022.
