Interpublic Group 909 Third Avenue New York, NY 10022 212-704-1200 tel 212-704-1201 fax

Revenue before billable expenses of $6.75 billion in the first nine months of 2024 decreased 0.9% compared with the same period in 2023. Compared to the first nine months of 2023, the effect of foreign currency translation was negative 0.3%, the impact of net dispositions was negative 1.6%, and the resulting organic increase of net revenue was 1.0%.

Operating Expenses

In the third quarter of 2024, total operating expenses, excluding billable expenses, restructuring charges, and amortization and impairment of acquired intangibles decreased 2.9%. In the first nine months of 2024, total operating expenses, excluding billable expenses, restructuring charges, and amortization and impairment of acquired intangibles decreased 0.9% when compared to the first nine months of 2023.

In the third quarter of 2024, staff cost ratio, which is total salaries and related expenses as a percentage of revenue before billable expenses, decreased to 65.3% compared to 66.3% for the same period in 2023. Total salaries and related expenses in the third quarter of 2024 were $1.46 billion, a decrease of 4.4% from a year ago. The decrease was primarily driven by decreased base salaries, benefits and tax, performance-based employee compensation expense and temporary help expense. In the first nine months of 2024, staff cost ratio decreased to 68.0% compared to 69.1% for the same period in 2023. Total salaries and related expenses in the first nine months of 2024 were $4.59 billion, a decrease of 2.4% from a year ago. The decrease was primarily driven by factors similar to those noted above for the third quarter of 2024, partially offset by increased severance expense.

In the third quarter of 2024, office and other direct expenses as a percentage of revenue before billable expenses increased to 14.6% compared to 13.8% for the same period in 2023. Office and other direct expenses were $327.1 million in the third quarter of 2024, an increase of 2.6% from a year ago, reflecting increased expenses for technology and software, as well as professional consulting. In the first nine months of 2024, office and other direct expenses as a percentage of revenue before billable expenses increased to 14.9% compared to 14.5% for the same period in 2023. Office and other direct expenses were $1.01 billion in the first nine months of 2024, an increase of 1.8% from a year ago, primarily due to increases in technology and software costs and general corporate expenses, partially offset by decreases in occupancy expense.

Selling, general and administrative ("SG&A") expenses were $20.8 million in the third quarter of 2024, compared to $16.9 million a year ago, primarily due to increased strategic investment in base salaries, benefits and tax and technology & software. SG&A expenses were $86.4 million in the first nine months of 2024, compared to $43.7 million a year ago, primarily due to factors similar to those noted above for the third quarter of 2024.

Interpublic Group 909 Third Avenue New York, NY 10022 212-704-1200 tel 212-704-1201 fax

Depreciation and amortization expense decreased by 1.1% and 1.8% during the third quarter and the first nine months of 2024, respectively.

During the third quarter and first nine months of 2024, we recorded goodwill impairment of $232.1 million.

Non-Operating Results and Tax

Net interest expense decreased by $2.9 million to $20.7 million in the third quarter of 2024 from a year ago, primarily attributable to higher interest rates, offset by lower average balances on net deposits. Net interest expense decreased by $10.8 million to $56.1 million in the first nine months of 2024 from a year ago, primarily due to factors similar to those noted above for the third quarter of 2024.

Other expense, net was $2.7 million in the third quarter of 2024, and primarily related to losses on sales of businesses and the classification of certain assets and liabilities as held for sale, as well as pension and postretirement costs. Other expense, net was $13.4 million in the first nine months of 2024, and primarily related to factors similar to those noted above for the third quarter of 2024.

The income tax provision in the third quarter of 2024 was $85.3 million on income before income taxes of $109.5 million.
