Abstract
The article discusses the problem of sub-threshold serial acquisitions, during which firms
obtain significant market power due to purchasing several small companies, which
individually remain below the level of mergers notification thresholds. Even though
competition laws mostly focus on reviewing major mergers, it is quite challenging for them
to recognize an accumulative effect of many small transactions changing the market structure
and weakening competition.
The author demonstrates how firms conduct various schemes, such as horizontal roll-ups in
highly fragmented industries and acquisitions of emerging rivals, which can potentially
compete in the future. The fact that every single transaction undergoes separate analysis
prevents regulators from seeing the trend in consolidation, resulting in a high level of market
concentration after integration of acquisitions.
Such problems manifest themselves in health services industry through acquisitions of
physician practices and healthcare organizations, leading to greater concentration and higher
costs. Another industry, which suffers from similar issues, is the digital economy, where tech
companies buy up smaller startups, talents, intellectual property, and data.
This article considers some potential solutions, such as the use of transaction thresholds,
market inquiries, sector-specific regulation, and mandatory reporting of serial acquirers. The
author’s conclusion is that successful regulation depends on switching from transaction-based
regulation to programme-based regulation.
