Omnicom has revealed the leadership and operating structure for its newly expanded operations, marking the most
consequential reorganization of a global holding company. The decision follows the closure of Omnicom’s acquisition of
the Interpublic Group, a deal that eliminates IPG as an independent entity and consolidates two of the world’s largest
agency networks at a moment of profound disruption for the advertising business.

Omnicom outlined the shape of its new, post-merger organization, consolidating creative, media and specialty services
under a streamlined structure that erases the remnants of the Interpublic Group name and redraws the boundaries of
several of Madison Avenue’s best-known networks.
The company’s creative division, now called Omnicom Advertising, will continue to be led by Troy Ruhanen, its current
chief executive and president. The unit brings together three global networks — TBWA, BBDO and McCann — while folding
DDB and MullenLowe will be absorbed into the TBWA network. All three legacy brands — FCB, DDB and MullenLowe — will
Omnicom Media, overseen by Florian Adamski, now encompasses OMD, PHD and Hearts & Science, along with former IPG
agencies Mediahub, Initiative and UM. The company said the combined operation forms the world’s largest media
organization by billings.
Duncan Painter will serve as chief executive of the Flywheel Commerce Network and OmniPlus, an upgraded iteration of
Omnicom’s Omni platform. Sergio Lopez will continue to lead Omnicom Production, which is being merged with IPG’s Craft.
Luke Taylor remains at the helm of Omnicom Precision Marketing, while Chris Foster will continue overseeing Omnicom
Most divisions will be led by longtime Omnicom executives. A notable exception is Omnicom Health, which will be run by
Dana Maiman of IPG Health. She will report to Michael Larson, chief executive of Omnicom Diversified Agency Services and
previously interim chief executive of Omnicom Health.
In a shift aimed at simplifying client management, every account will now be assigned a “client success leader,”
responsible for ensuring access to the right mix of talent, tools and capabilities across the network. These leaders
will report to Jacki Kelly, the company’s chief client and business officer and a former IPG executive, and to Andrea
Lennon, Omnicom’s chief client experience officer.
George Manas, previously chief executive of OMD Worldwide, will take on the role of chief growth and solutions officer,
charged with designing technology and data offerings for large enterprise clients.
Omnicom veterans Daryl Simm and Phil Angelastro will continue in their posts as chief operating officer and chief
financial officer, respectively. Philippe Krakowsky, the former IPG chief executive, will remain co-president and chief
operating officer of the merged company.
All entities bearing the IPG name — including IPG Health and IPG Mediabrands — have been retired.

Omnicom-level teams will accelerate the effectiveness of its Connected Capabilities and speed client-service innovation
through two integral enterprise-wide solutions:
Omnicom's Client Success Leaders (CSLs) – led by Jacki Kelley, Chief Client & Business Officer, and Andrea Lennon,
Client Experience Officer – will have senior accountability across all Connected Capabilities, providing holistic,
tailored solutions for individual client strategies and KPIs to enable client success.
Omnicom's Global Growth Team – led by George Manas, Chief Growth and Solutions Officer – will ensure an integrated,
enterprise-level view on client needs and innovative solutions across new business development. Manas will transition
from his current role leading OMD Worldwide effective February 1, 2026.
As previously announced, John Wren continues as Chairman & CEO, Phil Angelastro serves as EVP & CFO, and Philippe
Krakowsky and Daryl Simm serve as Co-Presidents and COOs.
The announcement, industry executives say, is expected to determine which agency brands survive, how overlapping
capabilities will be combined, and which leaders will guide one of the fastest-growing markets in Omnicom’s global
footprint. With India viewed internally as both a growth engine and a cost-efficient talent hub, the stakes around the
leadership configuration are unusually high.
Globally, the merger has created a $25-billion holding company that now sits atop the sector. The latest announcement
clarifies reporting lines for creative, media, CRM, data, PR and production units, several of which overlap
Agency leaders and clients across India have spent the past several weeks bracing for a wave of consolidation that could
reshape everything from pitch pipelines to staffing models. IPG’s recent filings — which disclosed 3,200 job losses this
year and significant office reductions — have intensified expectations that India could see brand retirements, office
consolidations and senior-level reshuffles. Omnicom has also previously signaled plans to streamline back-office
The local industry context adds new layers to the decision. India is in the middle of its own structural transformation:
marketers are rapidly shifting budgets to performance, digital commerce, influencer ecosystems and AI-enabled production
workflows. Storyboard18 has reported accelerating demand for integrated, outcome-driven partnerships and a decline in
AOR models, trends that make leadership clarity even more critical.
Clients, particularly in sectors such as FMCG, auto, financial services and tech, are watching for signs of stability.
Several expressed concern privately that extended uncertainty could disrupt campaign continuity, especially during a
period of macroeconomic sensitivity and rising executional complexity. At the same time, many see the merger as an
opportunity for broader data, CRM and measurement capabilities if Omnicom succeeds in combining its Omni platform with
IPG’s Acxiom assets in India.
The new structure is expected to steer the merged network in India and how major brands — including legacy creative and
media agencies — will be positioned. The decisions could influence talent movement across the industry, determine
competitive dynamics with Publicis and WPP, and set the tone for how aggressively the combined group intends to pursue
For now, the industry is bracing for a cascading impact. Recruiters report heightened inbound interest from senior
leaders. Independent agencies say they are fielding more conversations with clients seeking contingency options. And
several large marketers say they are preparing to reassess scopes once the new structure sets in.
As one longtime industry executive put it this week, “Whatever Omnicom announces in India won’t just affect Omnicom. It
will reset the center of gravity for the whole market.”
