CMA finds Macquarie's acquisition of Energy Assets Group may substantially lessen competition, threatens Phase 2 unless undertakings offered by 2 October
On 25 September 2026, the Competition and Markets Authority (CMA) issued its Phase 1 decision on Macquarie Asset Management's anticipated acquisition of Energy Assets Group (EAG), finding that the deal may be expected to result in a substantial lessening of competition in one or more UK markets. The parties have until 2 October 2026 to offer undertakings acceptable to the CMA; if none are forthcoming, the deal will be referred for a full Phase 2 investigation. The CMA separately decided not to refer the transaction under the special energy network merger provisions of the Enterprise Act 2002, concluding that the deal does not substantially prejudice Ofgem's ability to make comparisons between energy network enterprises when carrying out its statutory functions under the Gas Act 1986 or Electricity Act 1989. EAG provides electricity and gas metering services, data services, and independent installation and adoption services for last-mile utility connections. Macquarie Asset Management already holds significant UK utility interests, including stakes in Last Mile Infrastructure, National Gas, Cadent, and Southern Water, through various arms of the wider Macquarie Group. The formal merger inquiry was launched on 29 July 2026, following an invitation-to-comment period opened on 15 May 2026. The CMA's full Phase 1 decision text was expected to be published shortly after the announcement.
