When we think about suppliers and retailers working together, we usually imagine negotiations over things like the price a retailer pays for products, the quantities ordered, or delivery schedules. However, some suppliers do much more than simply supplying products. In fact, suppliers to many supermarkets also advise them on which brands to stock, how much shelf space each brand should get, and which products to promote. In this role, known as a ‘category captain’, a supplier can influence not only its own products but also those of its competitors within a specific category of products.
For example, if Red Bull were acting as a category captain in the energy drinks category for a supermarket like Tesco, it could also advise on where its competitor, Monster Energy, appears on the shelves, or even whether it appears at all!
Sounds problematic? Arrangements like these are an example of vertical relationships between suppliers and retailers, something economists often study. Like other vertical arrangements, such as exclusive dealing, they can have both benefits and drawbacks. For example, while a category captain can result in efficiency gains, allow for a more organised category of products and improve consumer choice, it also raises questions when the supplier giving the advice also competes with the products it is advising on.
That is exactly what the European Commission (EC), the EU’s competition authority, began examining in November 2025, when it opened an investigation into potential anticompetitive conduct by Red Bull.
One of the key concerns is whether Red Bull used its role as a category captain to disadvantage competing energy drink brands.
Category management is common … but novel for enforcement
The practice of appointing a category captain is not new. Many large supermarkets appoint category captains from major consumer goods suppliers. For example, firms such as Kraft Foods and Procter & Gamble have long taken on category management roles in a range of consumer-packaged goods categories.
However, despite how common these arrangements are in retail, this is the first time the EC has formally investigated whether a supplier has misused its category management role to limit or disadvantage competing products, and it has said it will treat the case as a priority.
How Red Bull could be disadvantaging competitors
According to the Commission, Red Bull appears to hold a dominant position in the wholesale supply of branded energy drinks, at least in The Netherlands. In competition policy, a firm which holds a dominant position has a special responsibility to ensure that its actions do not unfairly restrict competition. Regulators are investigating whether the company abused this position by offering financial or non-financial incentives and/or leveraging its role as a category captain to disadvantage competing energy drinks sold in larger can sizes.
At an extreme, a category captain could advise a supermarket to stop selling a competitor’s product entirely, effectively excluding the brand from the shelves and potentially reducing consumer choice.
But there are also more subtle ways Red Bull could disadvantage its competitors. Insights from behavioural economics suggest that the placement of products on shelves can strongly influence what consumers notice and buy. By reducing the visibility of rival energy drinks, for example, products in less prominent locations are less likely to be purchased and are therefore disadvantaged.
These practices matter for consumers as well as competitors. By limiting which products are stocked or how prominently they are displayed, dominant suppliers could reduce choice and potentially keep prices higher.
Growing scrutiny of category management?
Competition authorities seem to be paying closer attention to how suppliers influence the management of product categories in retail stores. In April 2025, the Belgian Competition Authority fined three large pharmaceutical companies more than €11 million for co-ordinating the placement of over-the-counter medicines in pharmacies. The companies had created shelf layouts that favoured their own products, disadvantaged competing brands, and monitored whether pharmacies followed the plans.
Thus far there have not been many European cases related to category management.
Why the Red Bull case matters
The Red Bull investigation is the first EC case focusing specifically on the potential misuse of category management by a dominant supplier. There is currently little guidance on how these arrangements should be assessed under competition law, meaning the case could set an important precedent.
If the Commission concludes that category management was used strategically to disadvantage competitors, Red Bull could be found to have abused its dominant position under EU competition rules. Such a decision could reshape supplier–retailer relationships across Europe.

The Digital Markets Act (DMA) outlines a new regulatory approach that the European Commission (EC) is taking to address concerns over the lack of competition in digital platform markets. The DMA complements existing European Union competition law and officially came into force on 1st November 2022.
In the first stage of this new regulatory approach, the EC identified ten core platform services (CPS). Examples include search engines, online social networking services, video sharing services, cloud computing services, web browsers and operating systems. These services act as important gateways for large numbers of businesses and consumers to interact with one another. They also have some important economic characteristics, such as large economies of scale and very strong network effects.
The next stage of the regulatory process was to assess which of the large established businesses should be designated as ‘gatekeepers’ of these CPS. To be judged as a gatekeeper, a business had to meet three qualitative criteria. Using quantitative thresholds as a guide to see if these qualitative criteria had been met, the following six companies were designated as gatekeepers by the EC in September 2023: Alphabet (Google’s parent company), Amazon, Apple, ByteDance (owner of TikTok), Meta (owner of Facebook) and Microsoft. Individual companies can be gatekeeper for more than one CPS. For example, Apple was judged to be a gatekeeper for both web browsers (Safari) and operating systems (iOS and iPadOS).
Rules and compliance
Once a business has been designated as a gatekeeper for one or more CPS, the DMA imposes a set of rules on its future conduct. Some of these rules refer to conduct that the business must follow, while others refer to types of behaviour that are prohibited. The EC sometimes refer to these rules as a list of “do’s” and “don’ts”.
One of the rules refers to interoperability. This is the degree to which different (a) software, (b) devices and (c) other applications can work seamlessly together (i.e. share functionality/data) without requiring any actions by the user (i.e. how compatible they are with one another).
For example, consider the degree of interoperability between the operating system of a gatekeeper, such as Apple, and other hardware/software services. One of the requirements of the DMA is for the gatekeeper to provide the same degree of interoperability for the hardware/software services provided by rival businesses as they do for similar hardware/software services they supply. This is sometimes referred to as the interoperability obligation.
Once a business is designated as a gatekeeper, it has 6 months to submit a compliance report to the EC that demonstrates how it is meeting the rules set out in the DMA. This should include descriptions of any changes the company has had to make to its conduct to meet the new requirements. Further compliance reports must then be submitted on an annual basis.
If, after assessing a compliance report, the EC suspects that a gatekeeper is still acting in ways that do not comply with the DMA, then it can launch either a non-compliance or specification procedure.
The case of Apple
Apple submitted its first compliance report on 7 March 2024. It was far less extensive than those completed by other designated gatekeepers and adopted a very different tone: it directly challenged the EC’s view that the DMA rules would have a positive impact on consumer welfare.
In September 2024, the EC launched its first two specification proceedings that focused on Apple’s compliance with the interoperability obligation.
The first of these proceedings opened a formal discussion with Apple over the interoperability between the iPhone operating system (iOS) and connected devices such as smartwatches and headphones. The proceeding identified nine features that gave the iOS greater functional compatibility with connected devices produced by Apple than with those made by other businesses. For example:
- Only users of connected devices produced by Apple can (a) receive iOS notifications that contain images or other attachments and (b) select the iOS notifications they want to appear on the device.
- Only users of Apple’s wireless headphones have intelligent audio switching functionality that allows them to switch automatically to the device playing the most relevant audio.
- The Airdrop function, which enables users to share files wirelessly between devices, only works if they are both produced by Apple.
- Only connected devices made by Apple have the functionality for high-bandwidth data transfer from an iPhone without having to rely on network or cellular connection. This is useful for gaming and AI services.
The second specification proceeding focused on the process developed by Apple to deal with requests from other businesses that wanted to develop hardware or software services that are compatible with the iOS.
On 18th December 2024, the EC informed Apple of its preliminary specification decisions and opened a consultation exercise with other interested parties about the suitability of its proposals. Once this process was completed, the EC informed Apple of its final specification decisions on 19 March 2025.
The EC’s decisions
The first decision included a set of measures that Apple must take to improve the interoperability of connected devices produced by other businesses with the iOS. The EC stated that:
The interoperability solutions for third parties will have to be equally effective to those available to Apple and must not require more cumbersome system setting or additional user friction.
The second decision outlined measures that Apple had to take to improve the process of dealing with requests for greater compatibility with the iOS. For example, it should provide outside businesses with more (a) access to technical documentation, (b) predictable timelines for the reviews and (c) timely updates.
Apple argued that being forced to introduce these measures will (a) create significant additional costs, (b) limit its ability to develop products that work seamlessly with one another and (c) lead to its having to share sensitive customer information with its rivals.
On 30th May 2025, Apple filed an appeal against the EC’s specification decisions to the General Court of the European Union. It will be interesting to see what judgment is made on this case by the General Court and the implications this has for the enforcement of the DMA.

The enforcement of Article 102 of the Treaty on the Functioning of the European Union (TFEU) by the European Commission (EC) tends to focus on exclusionary abuses by firms with significant market power. Exclusionary abuses are actions that limit or prevent competition, as opposed to exploitative abuses that directly harm the consumer, such as charging high prices.
The treatment of exclusionary abuses has evolved over time. Initially, the approach towards enforcement was form-based (i.e. the nature of the abuses), but this changed when the EC produced new guidelines in 2009 which signalled a move to a more effects-based approach.
The EC plans to produce a new set of guidelines in 2025 and published a draft version in August 2024 as part of the consultation process with businesses and other stakeholders. These draft guidelines indicate a partial shift back to a form-based approach. Any moves in this direction made by the EC are likely to influence both national-level competition authorities and the courts.
The form-based approach to policy enforcement
A form-based approach to the enforcement of Article 102 assumes that certain types of business conduct are inherently anti-competitive except in very exceptional circumstances. In other words, there is a presumption that the characteristics or form of the behaviour mean that it must have a negative impact on competition and consumer welfare in virtually all real-world cases.
With a form-based approach to enforcement there is no requirement for the authorities to carry out detailed case-specific analyses of business conduct as part of an investigation. This had been the approach adopted by the EC before 2009. It is possible, however, that the same form of business conduct could have anti-competitive effects in some market situations but pro-competitive effects in others. The EC was criticised for not making enough allowance for the chances of this happening.
The effects-based approach to policy enforcement
In response to this criticism the European Union published a new set of guidelines in 2009 which signalled that the enforcement of Article 102 was moving to a more effects-based approach. The effects-based approach uses economic analysis to assess the impact of a dominant firm’s conduct on a case-by-case basis. Context-specific evidence is examined by the competition authorities to see if the behaviour effectively excludes rival businesses from the market that are just as efficient as the dominant firm.
The use of economics in this effects-based approach gradually increased over time. Initially, the analysis was predominately based on theoretical arguments, but increasingly cases included sophisticated analysis of market-specific evidence using econometric models and market simulations. This, however, led to the following issues.
- The increasing use of complex economic analysis makes it more difficult to meet the evidentiary standards of the courts and prove a case. As the effects-based approach places a greater burden on the competition authorities to meet these evidentiary standards (i.e. provide evidence of case-specific anti-competitive effects of the conduct) it disproportionality affects their ability to prove cases.
- Businesses with significant market power are more likely to make large profits and so have access to greater resources than government-funded competition authorities. Therefore, they will be able to employ more economic consultants with the relevant technical expertise to (a) carry out the analysis and (b) communicate the findings effectively in a court case
This led to concerns that the competition authorities were losing cases where there was strong evidence of exclusionary conduct by the dominant firm.
In response to these concerns, the EC announced in 2023 that it would be revising its 2009 guidelines to improve enforcement of Article 102.
The draft guidelines
The draft guidelines published in August 2024 split different types of potentially anti-competitive conduct by dominant firms into three categories.
The first category includes types of conduct where there is a strong presumption of anti-competitive effects: i.e. the sole purpose of the business behaviour is to restrict competition. These types of conduct are referred to as a ‘naked restriction’ and the documentation provides the following three examples:
- making payments to customers (typically other businesses) on the condition that they cancel or postpone the launch of a product that uses inputs produced by the dominant firm’s rivals;
- threatening to withdraw discounts offered to suppliers unless they agree to supply the dominant firm’s product in place of a similar product produced by a rival firm;
- actively dismantling infrastructure used by a rival firm.
The guidelines indicate a form-based approach will be taken when investigating these types of conduct as the EC will not have to provide any case-specific evidence of anti-competitive effects. A business under investigation can challenge the presumption of anti-competitive effects with appropriate evidence, but the guidelines make it clear that this would only succeed in exceptional circumstances. In other words, it is highly unlikely that the conduct could ever be justified on pro-competitive grounds.
The second category of anti-competitive conduct includes actions that are also presumed to have a negative impact on competition. The presumption, however, is not as strong as with naked restrictions, so firms have a better chance of proving pro-competitive effects.
There is a form-based element towards this second category of conduct as the EC will not have to provide any initial case specific evidence of anti-competitive effects. But, if a business under investigation does submit evidence to challenge the presumption of anti-competitive effects, the EC must demonstrate that (a) it has fully assessed this evidence and (b) the evidence is insufficient to prove that the conduct does have pro-competitive effects. As part of this process, the EC can provide its own case-specific evidence. Therefore, for this second category of conduct, the initial burden of proof effectively shifts from the competition authority to the firm under investigation, making it more of a form-based approach. However, if the firm uses relevant evidence to appeal its case, the burden shifts back to the competition authority and becomes a more effects-based approach.
The third category includes types of conduct where the EC must initially provide case-specific evidence that it reduces competition. For this category of conduct, the approach towards enforcement remains the same as in the 2009 guidelines and an effects-based approach is adopted.
It will be interesting to see the extent to which the final guidelines (a) follow the approach outlined in the draft guidance and (b) influence the enforcement of Article 102 by the EC and other national-level competition authorities.

High-tech firms, such as Google, Amazon, Meta and Apple, have increasingly been gaining the attention of competition authorities across the world, and not in a good way! Over the past few years, competition authorities in the UK, USA and Europe have all opened various cases against Apple, with particular focus on its App Store (see, for example, a blog post on this site from 2021 about the Epic v. Apple case in the USA).
The lead-up to the €1.8 billion fine issued by the European Commission (Europe’s competition regulator) on the 4th March 2024, began in 2019 when music streaming provider, Spotify, filed a complaint against Apple, after years of being bound by the ‘unfair’ App Store rules imposed by Apple.1
Apple’s App Store has traditionally served as the only platform through which application developers can distribute their apps to iOS users, and app developers have had no choice but to adhere to whatever rules are set by Apple. As iPhone and iPad users know, the App Store is the only way in which users can download apps to their iOS devices, establishing Apple’s App Store as a ‘gatekeeper’, as described in the European Commission’s (EC) press release expressing their initial concerns in April 2021.2 When it comes to music streaming apps, Apple not only serves as the exclusive platform for downloading these apps, but also has its own music streaming app, Apple Music, that competes with other music-streaming providers.
This means that Apple holds a dominant position in the market for the distribution of music streaming apps to iOS users through its App Store. Being a dominant firm is not necessarily a problem. However, firms which hold a dominant position do have a special responsibility not to abuse their position. The EC found that Apple was abusing its dominant position in this market, with particular concerns about the rules it imposed on music streaming app developers.
Apple requires that app developers use Apple’s own in-app purchase system. This means that users must make any in-app purchases or subscriptions to music streaming apps through Apple’s system, subsequently subjecting app developers to a 30% commission fee. The EC found that this often led app developers to pass on these costs to consumers through an increase in prices.
Although users could still purchase subscriptions outside of the app, which may be cheaper for users as these payments will not be subject to commission, the EC found that Apple limits the ability for app developers to inform users about these alternative methods. For example, Apple prevented app developers from including links within their apps to their websites, where users could purchase subscriptions. The implications of this extends beyond increased prices for consumers, potentially resulting in a degraded user experience as well.
These restrictions imposed by Apple are examples of what are known as ‘anti-steering provisions’, and it is this conduct that led the Commission to issue the fine for the abuse of a dominant market position.
Whilst this case has now been concluded, the spotlight is not off of Apple yet. The European Commission had required that all ‘gatekeepers’ must comply with their Digital Markets Act (DMA) by the 7 March 2024.3 One implication of this for Apple, is the requirement to allow third-party app stores on iOS devices.
Whilst Apple has agreed to this requirement, concerns have been raised about the accompanying measures which Apple will introduce. This includes varying terms for app developers based on whether or not they offer their app exclusively through Apple’s App Store. As outlined in a recent article,4 one implication is that app developers exceeding 1 million existing downloads through the Apple App Store will incur a fee of €0.50 per additional user if they opt to distribute their app also through a competing app store. This may act as a deterrent to popular app developers to offer their app through a competing store.
The success of a platform like an app store, relies greatly on generating ‘network effects’ – more users attract more developers, leading to more users, and so on. Therefore, not being able to offer some of the most popular apps would make it challenging for a new app store to compete effectively with Apple’s App Store.
Recently, Spotify, along with game developer Epic and others, have expressed various concerns about Apple’s compliance with the DMA in a letter to the EC.5 It will be interesting to see whether the EC is satisfied with Apple’s approach to comply with the requirements of the DMA.

Record fines have been imposed by the European Commission for the operation of a cartel. Truck makers, Volvo/Renault, Daimler, Iveco and DAF have been fined a total of €2.93bn. The fines were considerably higher than the previous record fine of €1.7bn on banks for rigging the LIBOR rate.
Along with MAN, they were found to have colluded for 14 years over pricing. They also colluded in passing on to customers the costs of compliance with stricter emissions rules. Together these five manufacturers account for some 90% of medium and heavy lorries produced in Europe.
The companies have admitted their involvement in the cartel. If they had not, the fines might have been higher. MAN escaped a fine of €1.2bn as it had revealed the existence of the cartel to the Commission.
A sixth company, Scania, is still in dispute with the Commission over its involvement. Thus the final total of fines could be higher when Scania’s case is settled.
In addition, any person or firm adversely affected by the cartel can seek damages from any of the companies in the national courts of member states. They do not have to prove that there was a cartel.
The Commission hopes that the size of the fine will act as a disincentive for other firms to form a cartel. ‘We have, today, put down a marker by imposing record fines for a serious infringement,’ said Margrethe Vestager, the EU’s competition commissioner.
Also, by being able to exempt a cartel member (MAN in this case) from a fine if it ‘blows the whistle’ to the authorities, it will help to break existing cartels.
There are some other major possible cartels and cases of abuse of market power currently being considered by the Commission. These include Google and whether unfair tax breaks were given to Apple and Amazon by Ireland and Luxembourg respectively.
