Non-Horizontal Merger meaning

/nɒn:'hɒrɪˈzɒnt(ə)l/ /ˈməːdʒə/
What does Non-Horizontal Merger mean?
Describes a merger between businesses that are not direct competitors. It covers: (1) vertical mergers—firms at different levels of the supply chain (for example, manufacturer and distributor); and (2) conglomerate mergers—firms at the same level supplying products or services that are unrelated or complementary, so they do not compete. Non-horizontal merger is a descriptive competition-law term rather than a statutory definition; it is used in UK and Irish merger control by the CMA and CCPC and considered in case law and guidance. Such deals are assessed under the substantial lessening of competition test (Enterprise Act 2002; Competition Act 2002 (Ireland)). Key issues include ability and incentive to foreclose rivals (input or customer foreclosure), raising rivals’ costs, leveraging through bundling or tying and portfolio effects, and the exchange of competitively sensitive information. Potential efficiencies—such as elimination of double marginalisation or improved coordination along the supply chain—are also examined. Across the UK and Ireland, usage is broadly consistent. Although often less likely than horizontal mergers to harm competition, they may still attract scrutiny and remedies (access, non-discrimination and information-firewall commitments, occasionally structural divestment). Notification is mandatory in Ireland if thresholds are met; the UK regime is voluntary but subject to CMA call-in.

Global merger control: jurisdictions requiring notification of non-controlling minority shareholdings (checklist and thresholds)

Non-controlling minority shareholdings This Checklist identifies the jurisdictions worldwide where acquisitions of non‑controlling minority shareholdings must be notified, provided the other jurisdictional thresholds are satisfied. In this context, ‘non‑controlling minority shareholdings’ means any degree of influence falling short of what the EU Merger Regulation terms ‘decisive influence’—namely, the capacity to exercise a significant level of control over an undertaking’s strategic commercial behaviour. That influence can be exercised through a variety of routes, including share ownership, voting rights (in particular, veto rights), or contractual arrangements, and does not necessarily involve holding a majority shareholding...

Outsourcing and Competition Law: merger control triggers, anti‑competitive clauses, information‑sharing safeguards and sanctions—practical checklist

When assessing an outsourcing arrangement, a number of competition law considerations arise. From a competition viewpoint, the principal questions are: whether the deal constitutes a notifiable transaction under merger control regimes, and whether the prohibitions on anti-competitive agreements are engaged. Overlooking these points can have serious outcomes, from agreements being void and unenforceable to substantial financial penalties. This Checklist offers a high-level summary of key issues and how competition law may affect outsourcing arrangements. An outline of an outsourcing The hallmark of outsourcing is that one or more external suppliers provide the customer with services for business processes previously handled in-house. Companies frequently move non-core functions—particularly IT, finance and HR—to specialist suppliers, sometimes offshore, who can offer cost-effective delivery due to: lower labour costs more modern technology, and sharing technology and infrastructure to support multiple customers. The scope of services transferred is often sizeable and may constitute a significant part of the customer’s...

UK merger control: whether to notify the Competition and Markets Authority—jurisdiction, timelines, fees, IEO and unwinding risks, publicity, and ‘flying under the radar’ strategy checklist

This Checklist sets out the principal jurisdictional aspects of the UK merger control regime and provides practical direction for assessing whether to voluntarily notify a transaction to the Competition and Markets Authority (CMA), or alternatively, whether a tactical decision might be to proceed without notification in the hope of ‘flying under the radar’. Characteristics of the UK merger control system The merger control system of the UK diverges from most other jurisdictions in a number of respects: the UK’s merger control regime is voluntary by virtue of its non-suspensory nature...

UK CMA Phase 2 unconditional clearance: Viasat/Inmarsat - no SLC in broadband in-flight connectivity for commercial and business aviation (9 May 2023)

CASE HUB ARCHIVED This archived case hub sets out the status as at the decision date of 9 May 2023; it is not being updated. See further, timeline.
