EU's 2026 Merger Guidelines Shift Burden of Proof on Tech Deals

TL;DR\nThe EU's 2026 draft merger guidelines introduce a formal 'theory of benefit' that requires firms to prove efficiencies face the same scrutiny as harms. Critics warn the high evidentiary bar could turn this benefit into a burden, especially for tech deals needing long‑term innovation.\n\nContext\nOn April 30, 2026 the European Commission released draft merger guidelines, the biggest overhaul of EU competition policy since 2004. The new rules merge horizontal and non‑horizontal analysis into a single framework built around theories of harm and, for the first time, a formal 'theory of benefit'. Under this theory, merging parties must show that their deal creates efficiencies that benefit consumers, using the same proof standard applied to alleged anticompetitive effects.\n\nKey Facts\nThe guidelines mark the first major revision since the 2004 Merger Regulation. In the NVIDIA/Arm case, the parties argued that NVIDIA would not foreclose competitors and wanted them to thrive and succeed. The accompanying academic article proposes a rebuttable presumption that mergers of complementary assets in high‑innovation sectors generate dynamic efficiencies.\n\nWhat It Means\nAdvanced semiconductor firms argue that breakthrough research needs large scale and sustained capital, a point captured by the innovation‑scale paradox. Demanding deterministic, short‑term proof for probabilistic, long‑term gains may deter deals that could boost European technological capacity. If the rebuttable presumption is adopted, regulators would start with an assumption of benefit for certain tech shifts, shifting the burden to those claiming harm.\n\nWhat to watch next**\nThe Commission will finalize the guidelines later in 2026, and courts will begin testing the presumption in upcoming merger reviews, shaping how future tech consolidations are evaluated in Europe.
