The European Commission is increasingly scrutinizing data consolidation and access to commercially sensitive information in merger reviews, moving beyond traditional horizontal and vertical analysis. This shift requires companies to substantiate merger-specific efficiencies and account for regulatory constraints like the Digital Markets Act when justifying data-driven transactions.
The Commission's shift toward an 'entrenchment' theory of harm means streaming and digital platforms can no longer rely on privacy regulations like GDPR as a shield against merger intervention. By evaluating data through the 'four Vs' framework, regulators are targeting the strategic utility of information rather than just market share percentages. This creates a higher evidentiary burden for firms to prove that data consolidation leads to consumer efficiencies rather than just higher barriers for smaller rivals. The industry should closely monitor the upcoming Booking/eTraveli judgment, which will likely define the legal limits of this entrenchment doctrine for future tech acquisitions.
The European Commission's evolving approach to data in merger control has already produced concrete enforcement outcomes that illustrate the new framework's reach. In the Google/Fitbit case, the Commission approved the acquisition only after Google committed to maintaining data silos between Fitbit health data and its advertising stack for ten years, a remedy structure that directly reflects the four-Vs analysis by isolating volume and variety concerns. The Meta/Kustomer decision followed a similar pattern, with the Commission examining whether combining Meta's messaging data with Kustomer's CRM datasets would foreclose rivals from accessing customer-interaction signals at sufficient velocity to compete in the CRM market.
On the regulatory side, the Digital Markets Act now intersects with merger review in ways that did not exist before 2023. The DMA requires designated gatekeepers to comply with obligations covering data portability, profiling transparency, and consent for cross-service data combination, meaning that data-driven acquisitions by gatekeepers face a dual-track review where the Commission evaluates both competitive effects under the Merger Regulation and compliance with DMA obligations simultaneously. The Commission opened non-compliance investigations against Alphabet, Apple, and Meta in March 2024, including a probe into Meta's pay-or-consent model for combining user data across services, a direct test of how the four-Vs framework applies to data-consolidation practices that the merger playbook now scrutinizes at the transaction level.
In the broader enforcement landscape, the Commission has signaled that commercially sensitive information sharing between merging parties during due diligence receives heightened scrutiny under the new playbook. The Microsoft/LinkedIn and Verizon/Yahoo decisions established precedents for evaluating how access to rival data during integration can distort competition before a deal closes, a concern the new framework extends to post-merger data flows. Reuters reported that the EU's DMA investigations target whether gatekeepers' proposed compliance solutions genuinely prevent unfair data advantages over competitors, reinforcing the Commission's position that data access and combination remain central to both ex-ante regulation and ex-post merger control.
The European Commission has introduced a new data playbook for merger control, shifting focus toward how combined datasets entrench market power. By evaluating data through the 'four Vs'—volume, variety, velocity, and veracity—regulators are targeting the strategic utility of information, creating higher evidentiary burdens for tech companies during acquisition reviews.
The 'four Vs' are volume, variety, velocity, and veracity. Regulators use this framework to evaluate the strategic utility and practical usability of integrated datasets in transactions, moving beyond traditional market share analysis.
The DMA creates a dual-track review process. Designated gatekeepers must comply with obligations regarding data portability, profiling transparency, and consent, which the Commission evaluates alongside competitive effects under the Merger Regulation.
The Commission prefers structural remedies, such as divestments, over behavioral promises. They believe that simply promising to protect data is less effective than physically separating assets to prevent the entrenchment of market power.
The entrenchment theory of harm focuses on how merging parties use combined data to create higher barriers for smaller rivals. It allows the Commission to intervene in mergers even if traditional privacy regulations like GDPR are followed.
