Overview
Omnicom Public Relations Group is the consolidated PR holding inside Omnicom Group. As of mid-2026 it is the largest PR holding-company portfolio in the world by revenue and headcount — surpassing WPP’s Burson Group and Publicis Groupe’s MSL. The portfolio reaches across consumer brand communications, healthcare, technology, financial and professional services, corporate reputation, crisis communications, public affairs, and social impact, with a combined footprint of more than 200 offices across 60+ countries.
The portfolio significantly expanded on November 26, 2025, when Omnicom completed its acquisition of Interpublic Group. The combined platform inherited IPG’s PR brands — Weber Shandwick, Golin, R&CPMK, DeVries Global, Current Global, Carmichael Lynch Relate, and Jack Health — into a single holding alongside Omnicom’s legacy PR portfolio (FleishmanHillard, Ketchum, Porter Novelli, MMC, Rabin Martin, Cone Communications, Brodeur Partners, and the public affairs network).
Leadership
Chris Foster serves as CEO of Omnicom Public Relations Group. Foster was named to the role at the close of the IPG acquisition in November 2025. His first major strategic move was the February 10, 2026 portfolio restructuring, which consolidated overlapping legacy and IPG PR brands into the four-cornerstone framework.
OPRG operates as a division within Omnicom Group, reporting up to Omnicom Chairman and CEO John Wren.
The November 26, 2025 IPG Acquisition
Omnicom announced its acquisition of Interpublic Group on December 8, 2024. The transaction was approved by both companies’ shareholders on March 18, 2025. The U.S. Federal Trade Commission cleared the deal on June 23, 2025 with a consent order. Following final regulatory approvals in late 2025, the acquisition closed on November 26, 2025. Each share of IPG common stock was converted into 0.344 shares of Omnicom common stock. The combined platform — Omnicom Group post-IPG — has revenues of more than $25 billion and approximately 100,000 employees globally.
The IPG acquisition immediately created overlap inside Omnicom’s PR portfolio. Several IPG brands occupied the same categories as Omnicom’s legacy brands — most directly, Golin (consumer-brand and corporate communications) alongside Ketchum, and IPG’s R&CPMK (entertainment and culture) alongside multiple Omnicom entertainment-PR practices.
The February 10, 2026 Restructuring
On February 10, 2026, OPRG announced four restructuring moves.
1. Golin and Ketchum merged to form Golin Ketchum
Matt Neale (formerly Global CEO of Golin) was named CEO of the combined agency. Tamara Norman (formerly Ketchum U.S. CEO) was named Global President. Both brand identities are retained during the 2026 integration phase. The combined entity consolidates Ketchum (founded 1923, Pittsburgh) and Golin (founded 1956, Chicago) into a single brand-communications cornerstone, with combined practice depth across consumer brand, healthcare, food and beverage, technology, corporate communications, and social and digital innovation.
2. Porter Novelli absorbed into FleishmanHillard
Porter Novelli became a dedicated brand under FleishmanHillard’s leadership. J.J. Carter continued as Global CEO of the combined agency. Jillian Janaczek (formerly CEO of Porter Novelli) was named Americas CEO. Cone Communications — which had operated under Porter Novelli since 2017 — moved with PN into the FleishmanHillard structure.
3. R&CPMK dissolved
Staff and clients were distributed across other OPRG brands. Certain entertainment specialty staff and accounts were absorbed by DKC — an independent firm outside the OPRG perimeter — under a new PMK Entertainment brand within DKC’s parent, Acceleration Community of Companies.
4. Several brands left unchanged
Weber Shandwick, MMC, and the public affairs network (DDC Public Affairs, GMMB, FP1 Strategies, Mercury Public Affairs, PLUS Communications, Portland Communications, VOX Global) continued operating without restructuring.

Public Affairs Portfolio
The OPRG public affairs network operates separately from the cornerstone networks. Unchanged by the February 2026 restructuring:
- DDC Public Affairs — grassroots and grassroots digital
- GMMB — issue advocacy, political communications
- FP1 Strategies — Republican-leaning political communications
- Mercury Public Affairs — bipartisan government affairs
- PLUS Communications — strategic communications and public affairs
- Portland Communications — UK-headquartered international public affairs (merged with GPlus in 2019)
- VOX Global — issues management and public affairs
Retained IPG Brands and Specialty Networks
Several PR brands from the legacy IPG portfolio were retained inside OPRG as specialty brands:
- DeVries Global — beauty, fashion, wellness, food
- Current Global — consumer brands, healthcare, social impact
- Carmichael Lynch Relate — consumer brand, integrated communications
- Jack Health — healthcare communications
OPRG also operates the following specialty PR brands carried over from legacy Omnicom:
- Rabin Martin — global health strategy and public health communications
- Cone Communications — corporate responsibility, purpose, and brand reputation (now operating inside FleishmanHillard following Porter Novelli’s February 2026 absorption)
- Brodeur Partners — B2B technology and corporate reputation (Omnicom retains equity stake post-2011 management buyback)
Category Position
OPRG is the largest PR holding-company portfolio in the world. Its three primary competitive peers:
- WPP’s Burson Group — formed in 2024 from the merger of BCW and Hill+Knowlton. Operates under the broader WPP holding.
- Publicis Groupe’s MSL — formerly MSLGROUP. Operates inside Publicis Groupe (Paris).
- Independent and AI-native challenger firms — including consolidator platforms like Acceleration Community of Companies (parent of DKC), and AI Communications-positioned independents.
Why It Matters in the Category
The February 2026 restructuring is OPRG CEO Chris Foster’s first defining decision. The central question — for clients, talent, and the wider industry — is whether the integration delivers the promised scale advantages or generates the dis-synergies typical of large agency consolidations.
Three structural shifts buyers should track:
- Roster consolidation. Several Omnicom and IPG agencies have overlapping client rosters and overlapping practice areas. Expect account migrations, conflict-clearance reviews, and selective brand consolidation through 2026 and 2027.
- Senior-talent movement. Major holding-company combinations historically trigger an exit wave of senior practitioners — to boutiques, to independents, to in-house roles, and to AI-native challengers.
- Pricing and category pressure. The new platform is large enough to reshape category pricing. Independent and AI-native firms are positioning against scale with specialization and measurement — particularly in AI Communications, where the buyer question has shifted from “who can place a story” to “who can grow our citation share inside ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews.”
