10.1 Generally, vertical mergers122 only raise concerns when they increase barriers to entry or facilitate upstream coordinated behaviour. In addition to the conditions described below, the Bureau analyzes the competitive effects of such mergers by examining market concentration, the effectiveness of remaining competition, the availability of acceptable substitutes, entry, change and innovation, and the removal of a vigorous and effective competitor.
10.2 A vertical merger may raise concerns where the elimination of an independent upstream source of supply (or downstream distribution outlet) leaves only a small amount of unintegrated capacity123 at either of the stages at which one of the merging parties operates. In particular, concerns may be raised when the amount of unintegrated capacity at one stage (the secondary market) is sufficiently small that an entrant into the other stage (the primary market) will consider it necessary to simultaneously enter the secondary market. In general, where such simultaneous entry into both the primary and secondary markets involves incurring greater sunk costs than what is required to enter into the primary market alone, barriers to entry into the primary market are effectively raised.124
10.3 Increased barriers to entry into a primary market only presents grounds for concern under the merger provisions of the Act where the degree of actual competition that remains post-merger is so low that it would be possible for a new entrant to exercise an important constraining influence on prices in the market, but for the merger.
10.4 The Bureau is not likely to conclude that a vertical merger is likely to prevent or lessen competition substantially unless:
10.5 In determining whether simultaneous entry will be more difficult or less profitable, the Bureau examines whether entrants in such circumstances are likely to face higher costs of capital than incumbents, due to greater risks involved in attempting successful two-stage entry. An assessment is also made of the difference in the levels of minimum-efficient-scale in the primary and secondary markets and whether it is likely to impose significant additional costs on a two-stage entrant.
10.6 A merger that creates or increases a high degree of vertical integration between an upstream market and a downstream retail market can facilitate coordinated behaviour by firms in the upstream market by making it easier to monitor the prices charged by rivals at the upstream level.
10.7 In general, such mergers are not likely to prevent or lessen competition substantially unless:
122 A vertical merger involves the combination of the assets of a firm selling a product or service with a firm buying that product or service.
123Unintegrated capacity refers to capacity at only one of the stages in question.
125The Commissioner is unlikely to consider that second stage entry is required where post-merger sales (or purchases) by unintegrated firms in the secondary market would be sufficient to service two minimum efficient-scale operations in the primary market.
