It has been another seismic year for acquisitions across adland, martech, and media giants.
Omnicom completed its transformative $13 billion merger with IPG to create the world's largest agency holding company, Publicis piled on strategic APAC and data bolt-ons amid a martech surge, Havas grabbed indie scale in ANZ, challenger Stagwell eyed regional relevance through ADK Global, and Netflix stunned Hollywood with its $82.7 billion bid for Warner Bros' studios and streaming empire.
As privacy tightened, adtech focused on AI identity and precision, while holding groups sought APAC agility and creator power to offset consolidation.
So without further ado, here's a breakdown of the top M&A deals in 2025:
1. Omnicom swallows IPG in $13 billion merger: agencies culled, APAC leadership rejigged amid shakeup
Acquirer: Omnicom Group
Acquired: Interpublic Group (IPG)
Announced 9 December 2024 and finalised 26 November 2025 after regulatory hurdles including EU clearance, Omnicom’s all-stock $13.25 billion acquisition of IPG created the world’s largest agency powerhouse but not without significant disruption. Around 10,000 jobs, roughly 8% of the combined workforce, are being cut, including the sunset of legacy agencies DDB, FCB, and MullenLowe, which were folded respectively into TBWA and BBDO, streamlining the creative network to three global powerhouses. IPG-branded media and health units were dissolved or absorbed in pursuit of over $750 million in synergy savings.
Critics label it no merger of equals, with Omnicom’s stronger balance sheet swallowing a stagnant IPG (flat revenues over multiple quarters), while CEO John Wren takes definitive control and IPG's Philippe Krakowsky accrues a $48.6 million golden parachute to ease his landing to co-president and COO. Experts warn of client disruption and creative dilution risks amid forced consolidations, though the combined behemoth boasts enhanced data, CRM and digital capabilities.
Major leadership rejigs in APAC reflect this scale-up, with new heads appointed over India, China and Southeast Asia as Omnicom-IPG seeks to sharpen its regional competitive edge, though concerns linger about balancing growth innovation against mere cost cuts and media leverage. The fallout has opened opportunity windows for independents to capture disaffected clients amid the 'fourth big bang' of adland consolidation.

2. Stagwell swallows ADK Global in $24 million APAC bolt-on: challenger grabs regional scale but risks integration indigestion
Acquirer: Stagwell
Acquired: ADK Global
Announced 16 January 2025 as Stagwell's opening acquisition of the year, this $24 million deal vacuumed up ADK Global, the Japan-rooted integrated marketing network spanning 10 APAC markets from China and India to Thailand, thrusting Stagwell's regional headcount beyond 2,000 across 14 countries.
Stagwell rebranded ADK Global as ADK Global Powered by Assembly, with Richard Brosgill doubling up as CEO of Assembly APAC and head of the combined operations across the region. The deal was hailed as a smart counter to the Omnicom-IPG behemoth, arming Stagwell for pitches to LG, Google and Adidas with ADK's local nous atop its AI/digital stack, yet critics took aim at the lack of hard synergies or cost discipline, questioning if the move added true scale or was another opportunistic add-on for a mid-tier player punching above its weight in a consolidating adland.
No roles were cut in the merger, with both sides stressing it was not a cost-cutting exercise. "There’s no immediate or planned impact on headcount this year. We're focused on shaping the relationships and team structures over time," said Richard Brosgill, now CEO of the combined business, in an interview with Campaign Asia-Pacific. "This is not a cost synergy play. We aim to retain the strength of the core teams, avoid disrupting portfolios on either side, and quickly enable shared services and capabilities, from left-hand to right-hand, to grow the overall pie together," he added.
Brosgill and Yasuyuki Katagi were adamant about not mimicking a holding-company model. “The market doesn’t need another Publicis or WPP. What we’re building is sharper, more agile, and more in tune with how clients want to work today.” “We’re not the biggest,” said Katagi. “But we’re aiming to be the best alternative.”

3. Publicis Groupe acquires HEPMIL Media Group to fuse data and creator clout
Acquirer: Publicis Groupe
Acquired: Hepmil Media Group (parent company of SGAG, MGAG, PGAG)
Announced in October 2025, Publicis Groupe’s acquisition of Singapore-based Hepmil Media Group marked a bold move to deepen its social commerce and creator marketing capabilities across Southeast Asia. Best known for SGAG, MGAG and PGAG, digital humour platforms that attract more than 30 million regional followers, Hepmil brings strong local cultural traction to Publicis’ data-driven portfolio.
The deal integrates Hepmil’s creator network and branded content studios with Publicis’ Epsilon data stack, allowing the group to blend first-party identity insights from over 800 million profiles with localised storytelling and influencer strategies. The aim is to offer clients precision-targeted, culturally resonant social campaigns in a region where youth engagement and short-form content dominate.
For Publicis, the move sharpens its APAC growth story beyond traditional media and into platform-native creativity. For Hepmil, it brings scale, infrastructure and access to multinational client networks, though the challenge will be maintaining its irreverent local voice under global ownership.

4. Publicis Groupe ANZ acquired Atomic 212° to bolster media capabilities in Australia
Acquirer: Publicis Groupe ANZ
Acquired: Atomic 212° (Australia)
Announced on 27 January 2025, Publicis Groupe ANZ acquired Australia’s largest independent media agency, Atomic 212°, founded in 2008 with offices across Sydney, Melbourne, Brisbane, Adelaide and Darwin. Financial terms were not disclosed, though trade estimates valued the deal at A$35–50 million based on billings and revenue. Known for performance-driven planning, analytics and awards success (including Campaign ANZ and Global Agency of the Year in 2023–24), Atomic 212° joined Publicis Media alongside Spark Foundry, Zenith, Starcom and MBM.
The agency’s leadership team, including chairman Barry O’Brien and CEO Rory Heffernan, remained in place under a four-year earn-out, retaining equity while integrating into Publicis’ structure. The move accelerated Publicis’ growth in digital media channels that rose faster than traditional ones, combining Atomic 212°’s agile model with Epsilon’s identity-driven data for sharper client solutions across APAC. Analysts saw it as a competitive counter to GroupM and Omnicom Media Group’s scale.
Atomic 212's leadership team (L-R): Barry O'Brien (chairman); James Dixon (chief data officer & partner); Lorraine Woods (chief investment and trading officer); Rory Heffernan (CEO); Ashleigh Carter (GM, Sydney); Tom Sheppard, (GM, Media & Technology)
5. Havas acquires indie media agency Kaimera to boost ANZ scale and AI capabilities
Acquirer: Havas
Acquired: Kaimera (Australia/New Zealand)
Havas acquired independent media agency Kaimera, founded in 2016 with over 50 staff across Sydney, Melbourne and Auckland, strengthening its ANZ presence amid regional growth ambitions. The agency, known for simplifying media complexity and custom solutions for clients like Nando’s, Afterpay and BritBox, joined Havas Media Network as 'Kaimera, a Havas Company', with founders Nick Behr and Trent McMillan retaining leadership and reporting to Group CEO James Wright.
Financial terms remained undisclosed, but the deal expanded Havas ANZ’s headcount beyond 450, aligning with its 'Deliberately Different' positioning that blends indie agility with global scale. Kaimera joined Havas’ Converged.AI platform for strategy, CX, and media delivery, gaining new tools, investment, and regional growth while keeping its indie spirit.
Havas Chairman and CEO Yannick Bolloré saw the move as reinforcing commitment to ANZ markets and accelerating AI deployment for client excellence, with an aim to position Havas for 2026 momentum against larger holding group rivals.
6. Publicis Groupe acquired Lotame to boost AI identity data capabilities
Acquirer: Publicis Groupe
Acquired: Lotame (data infrastructure)
Publicis Groupe acquired Lotame in 2025 to strengthen Epsilon with AI-driven identity resolution and cross-device targeting for a cookieless world. Lotame provides universal ID systems and clean room tech for precise audience segmentation, integrating with Epsilon's 800 million+ profiles to enhance CRM and performance media in Publicis' Power of One model.
Financial terms were undisclosed but Lotame previously said it raised at least $44 million from external investors. The deal accelerated Publicis' first-party data strategies, positioning it ahead in privacy-compliant personalisation against big tech and rivals like Omnicom.
7. The Trade Desk acquired Sincera to enhance programmatic data insights
Acquirer: The Trade Desk
Acquired: Sincera (digital advertising data company)
Announced 14 January 2025 and closed Q1 2025, The Trade Desk acquired New York-based Sincera to provide objective metadata on publisher data quality, improving ad impression valuation across streaming TV, digital audio, and retail media. Sincera, a prior Trade Desk partner and investor (via its VC arm in 2023), offered actionable insights for campaign optimisation without selling data itself.
The deal integrated Sincera’s tools into The Trade Desk’s DSP, giving advertisers clearer views on inventory and helping publishers prioritise valued data signals for better fill rates and demand. It marked The Trade Desk’s second public acquisition after Adbrain (2017), countering supply-side competition with buyer-focused transparency.
The move is seen as a strategic upgrade for programmatic performance in a fragmented, multi-channel landscape, aligning with 2025 adtech trends toward trusted, independent data amid privacy changes.
8. Netflix bids for Warner Bros. studios and streaming in landmark $82.7 billion deal
Acquirer: Netflix
Target: Warner Bros. Discovery (studios, film/TV production, HBO, HBO Max)
Announced 5 December 2025, Netflix has entered advanced negotiations to buy Warner Bros. Discovery's core studio and streaming assets for an enterprise value of $82.7 billion, amid a heated bidding war with rivals including Paramount Skydance and Comcast. The proposed transaction, if finalised, is expected to close in Q3 2026 subject to regulatory approval, with a $5.8 billion Netflix reverse breakup fee and $2.8 billion Warner fee outlined in current terms.
Should the deal proceed, Netflix would gain Warner's century-old library (including Harry Potter, DC Comics, Game of Thrones) plus HBO Max's 128 million subscribers, pushing its base beyond 420 million and bolstering franchises amid slowing growth. Netflix has pledged commitments to theatrical releases, expanded US production, and $2-3 billion in annual synergies by year three, integrating HBO content into bundles, though antitrust scrutiny from EU/US regulators and potential Hollywood pushback remain significant hurdles.
The ongoing talks signal Netflix's push into studios, blending scale and IP in a crowded streaming market, though competing bids, including Paramount's $25 billion higher offer, leave the outcome uncertain.
