WPP today reported revenue gains of 7.6 percent on a constant currency basis during 2016’s third quarter, with like-for-like revenue growth of 3.2 to account for £3.6 billion (about $4.4 billion).

The British ad/PR conglomerate also posted net sales growth of 7.8 percent for the year-to-date ending September 30, with net sales growth of 2.8 percent on a like-for-like basis.

Activity in North America saw noted gains compared to the previous quarter, revealing revenue growth of 4.3 percent and 2.6 percent on a like-for-like basis.

It was WPP’s PR and public affairs operations, however, that experienced the most impressive gains this quarter. That division, which includes agencies Ogilvy Public Relations, Cohn & Wolfe, Burson-Marsteller, Finsbury and Hill+Knowlton Strategies, saw Q3 revenue growth of 8.5 percent — 5 percent on a like-for-like basis — to £287 million (about $350 million), making it the advertising and PR giant’s strongest performer for the period.

WPP specifically cited activity at subsidiaries Cohn & Wolfe, Finsbury and content and digital strategy shop SJR. Earlier this year, the WPP had reported that its PR and public affairs revenues climbed 8.8 percent in the first half of 2016 to $661 million.

For the nine months ending Sept. 30, revenues at WPP’s PR and PA properties were £786 million (about $960 million), revealing revenue growth of 6 percent and 3.5 percent on a like-for-like basis. Net sales were also up 8.2 percent and 5.1 percent on a like-for-like basis for the quarter, with all regions revealing positive sales gains, though particularly strong performances were seen in the United Kingdom, Continental Europe, Latin America and Africa, WPP noted in its quarterly results announcement.

WPP CEO Sir Martin Sorrell in a statement said “the pattern for 2016 looks very similar to 2015,” though operating profit is “well above budget and ahead of last year,” and the agency conglomerate sees “little reason, if any, for this pattern of behaviour to change in 2017.”

Looking ahead to next year, Sorrell said WPP sees “no reason why revenue and net sales cannot continue to grow at over 3 percent in 2017, a very similar pattern to 2015 and 2016. Our new business record remains strong, despite recent bumps.”

WPP celebrates its 30th anniversary this year.
