"We are pleased with our financial performance this quarter. Our industry leading organic growth is a tribute to the competitiveness of our offerings and strength of our talent. Our results in the second quarter were led by strong top-and bottom-line performance in media, as well as growth from our global creative networks, and our public relations and digital offerings.

Our second quarter was also highlighted by growth across a broad range of client sectors, including healthcare, financial services, consumer goods and retail. Our performance is a reflection of the strength of our offerings, our people and our differentiated strategy. We continue to be pleased with Acxiom, as it has given us an unrivaled industry position in data management capabilities, allowing us to help marketers get the best out of all their data assets,” said Michael I. Roth, Interpublic’s Chairman and CEO.

“At mid-year, we are confident that our performance to date and the current tone of the business have us on track to deliver growth at the high end of the 2-to-3% organic growth target set at the beginning of the year. In addition, we continue to be comfortable with our target for adjusted EBITA margin expansion of 40-50 basis points over last year’s 13.5%. We view our current performance and long-term strategy as the basis for significant shareholder value creation.”

Operating Results

Revenue

Net revenue of $2.13 billion in the second quarter of 2019increased9.1% compared with the same period in 2018. During the quarter, the effect of foreign currency translation was negative2.4%, the impact of net acquisitions was positive8.5%, and the resulting organic net revenue increase (which excludes results from Acxiom) was 3.0%. This was comprised of an organic net increase of 0.6% in the U.S. and 6.5% internationally, attributable to a combination of net client wins and net higher spending from existing clients. Total revenue of $2.52 billion in the second quarter of 2019 increased 5.4% compared with the same period in 2018.

Net revenue of $4.13 billion in the first half of 2019increased11.0% compared with the same period in 2018. During the first half of 2019, the effect of foreign currency translation was negative2.5%, the impact of net acquisitions was positive8.9%, and the resulting organic net revenue increase (which excludes results from Acxiom) was 4.6%. This was comprised of an organic net increase of 3.0% in the U.S. and 7.1% internationally, attributable to a combination of net client wins and net higher spending from existing clients. Total revenue of $4.88 billion in the first half of 2019 increased 7.0% compared with the same period in 2018.

Operating Expenses

For the second quarter and first half of 2019, operating expenses increased compared to the same periods in 2018 primarily due to the inclusion of Acxiom.

During the second quarter of 2019, salaries and related expenses were $1.38 billion, an increase of 6.8% compared to the same period in 2018. During the first half of 2019, salaries and related expenses were $2.80 billion, an increase of 6.8% compared to the same period in 2018.

Staff cost ratio, which is total salaries and related expenses as a percentage of net revenue, was 65.0% in the second quarter of 2019 compared to 66.4% in the same period in 2018, and was 67.8% in the first half of 2019 compared to 70.5% in the same period in 2018, primarily driven by leverage in base salaries, benefits and tax and temporary help expenses. The improved ratio was a result of carefully managing our employee base in addition to the inclusion of Acxiom, which had a lower ratio of salaries and related expenses as a percentage of its net revenue.

During the second quarter of 2019, office and other direct expenses were $387.3 million, an increase of 16.2% compared to the same period in 2018. During the first half of 2019, office and other direct expenses were $776.5 million, an increase of 18.2% compared to the same period in 2018.

Office and other direct expenses were 18.2% of net revenue in the second quarter of 2019 compared to 17.1% a year ago, and were 18.8% in the first half of 2019 compared to 17.7% in the same period in 2018. The higher expense ratio is primarily due to the inclusion of Acxiom which has a higher ratio of office and other direct expenses as a percentage of its net revenue, mainly driven by client service costs.

During the second quarter of 2019, selling, general and administrative expenses of $18.1 million decreased 37.2% compared with the same period in 2018 and during the first half of 2019, selling, general and administrative expenses of $59.5 million decreased 6.9% compared to the same period in 2018, primarily attributable to an increase in allocated service fees, mainly as a result of the inclusion of Acxiom, and lower professional fees, partially offset by higher incentive expense.

Selling, general and administrative expenses were 0.8% of net revenue in the second quarter of 2019 compared to 1.5% a year ago, and were 1.4% in the first half of 2019 compared to 1.7% in the same period in 2018.

Depreciation and amortization increased 65.9% to $73.0 million during the second quarter of 2019 compared to a year ago, and increased 60.1% to $144.1 million in the first half of 2019 compared to a year ago, primarily due to the inclusion of Acxiom.

Depreciation and amortization as a percentage of net revenue was 3.4% in the second quarter of 2019 compared to 2.3% the same period in 2018, and was 3.5% in the first half of 2019 compared to 2.4% in the same period in 2018.

During the second quarter and first half of 2019, restructuring charges were $2.1 million and $33.9 million, respectively, due to the implementation of a cost initiative to better align our cost structure with our revenue, primarily related to client losses occurring in 2018.

The income tax provision in the second quarter of 2019 was $43.6 million on income before income taxes of $216.5 million, compared to a provision of $63.6 million on income before income taxes of $211.5 million in the same period in 2018.

The income tax provision in the first half of 2019 was $54.1 million on income before income taxes of $217.8 million, compared to a provision of $76.3 million on income before income taxes of $210.0 million in the same period in 2018.
