When Does Competition Law Become a Business Risk in Türkiye?

Competition law is often associated with dramatic cartel investigations, large corporate mergers, or major technology companies. In reality, competition-law exposure can begin much earlier—during an ordinary conversation with a competitor, the drafting of a distribution agreement, a tender process, a pricing decision, or an acquisition that initially appears straightforward.

For companies doing business in Türkiye, understanding when a commercial decision crosses into competition-law territory is therefore more useful than memorizing a list of prohibited practices.

The central legislation is Law No. 4054 on the Protection of Competition, administered principally by the Turkish Competition Authority and the Competition Board. The Authority's official resources provide access to the Law No. 4054 on the Protection of Competition, Competition Board decisions, guidelines and regulatory announcements.

The important point for businesses is that competition law is not simply a matter for lawyers after a problem occurs. It can influence how companies negotiate, sell, distribute, acquire, cooperate and compete.

Competition Law Is About How Businesses Compete

A common misconception is that competition law only concerns companies that have become "too powerful."

That is only part of the picture.

Turkish competition law can become relevant where businesses:

• Coordinate with competitors;

• Restrict competition through agreements;

• Exchange competitively sensitive information;

• Abuse a dominant market position;

• Structure mergers or acquisitions;

• Establish certain joint ventures;

• Use restrictive distribution arrangements;

• Participate in potentially coordinated tender activity;

• Operate digital platforms with significant market power.

The legal question is usually not simply "Is this business activity legal?"

It is more specific:

Could this conduct restrict, distort or prevent competition in a way prohibited by Turkish competition law?

That question requires consideration of the relevant market, the parties involved, the purpose and effect of the conduct, market power, economic circumstances and the applicable provisions.

The Three Competition-Law Questions Every Turkish Business Should Ask

Before looking at particular types of conduct, businesses can use a simple framework.

Are We Acting With a Competitor?

If the answer is yes, competition law deserves immediate attention.

A conversation with a supplier is different from a conversation with a direct competitor. Discussions with competitors concerning future prices, discounts, customers, output, territories or commercial strategy can create significant risks.

The fact that a discussion takes place informally does not necessarily make it legally insignificant.

A WhatsApp message, email, industry meeting, conference discussion or telephone call may become relevant if regulators later investigate the conduct.

Are We Restricting Someone's Ability to Compete?

A second question concerns the commercial effect of an arrangement.

For example, a company may impose restrictions on a distributor, retailer or business partner. The restriction might concern territory, customers, pricing, online sales or exclusivity.

The commercial purpose may be legitimate, but the competition-law consequences still need to be considered.

Do We Have Significant Market Power?

Market power becomes particularly important when assessing potential dominance.

A company does not violate competition law merely because it is successful, innovative or commercially strong. The legal analysis is more nuanced.

The relevant questions can include:

• What is the relevant product market?

• What is the relevant geographic market?

• How easily can customers switch?

• What alternatives are available?

• How difficult is market entry?

• How strong are competitors?

• Does the undertaking have substantial market power?

• What exactly is the company doing with that position?

This is why a competition assessment should not be reduced to a market-share calculation.

Why Agreements Between Competitors Require Special Care

Some of the most serious competition-law concerns arise when independent competitors coordinate their behavior.

Article 4 of Law No. 4054 addresses agreements and concerted practices that have the object or effect of preventing, restricting or distorting competition.

The obvious example is price fixing.

But the risk can extend much further.

Price Coordination

Competitors should generally make their pricing decisions independently.

Potentially problematic discussions can involve:

• Future prices;

• Planned price increases;

• Discounts;

• Minimum prices;

• Pricing formulas;

• Promotional campaigns;

• Customer-specific pricing;

• Costs or margins.

A competitor saying, "We intend to increase prices next month" may appear like harmless market information. In the wrong circumstances, however, communications of this kind can become highly significant.

Customer or Market Allocation

Competitors should also be cautious about discussions concerning who will serve which customer or geographical area.

Arrangements such as:

• "You take these customers and we will take those";

• "You operate in this region and we will stay in that region";

• "You do not bid for this client";

• "We will not compete with each other";

can raise serious competition-law concerns depending on the circumstances.

Tender Coordination

Tender procedures require particular care.

Competitors should make their bids independently and should not coordinate the outcome.

Potential risks include:

• Cover bids;

• Bid rotation;

• Agreeing who will win;

• Dividing tenders;

• Sharing confidential bid information;

• Coordinating prices;

• Agreeing not to compete.

Businesses participating in Turkish public procurement should also consider the applicable Public Procurement Authority framework in addition to competition law.

The Information-Exchange Problem Businesses Often Underestimate

One of the less obvious competition-law risks concerns information.

Businesses frequently collect market intelligence. They speak to customers, suppliers, consultants, trade associations and industry participants.

There is nothing inherently unlawful about understanding a market.

The difficulty begins when competitors exchange information that may reduce uncertainty about each other's competitive behaviour.

What Information Can Be Sensitive?

Depending on the circumstances, information concerning the following may be particularly sensitive:

• Future prices;

• Planned discounts;

• Customer lists;

• Sales volumes;

• Production plans;

• Capacity;

• Costs;

• Margins;

• Commercial strategies;

• Future product launches;

• Bidding intentions.

The context matters.

For example, an old and publicly available industry statistic is not necessarily equivalent to a competitor sharing its confidential future pricing strategy.

Trade Associations Need Competition Rules Too

Trade associations can provide legitimate benefits by allowing businesses to discuss industry standards, technical developments and regulatory matters.

But participation should not become an opportunity for competitors to coordinate their commercial behaviour.

Companies should consider establishing internal procedures before attending industry meetings, particularly where direct competitors will be present.

Employees should know:

• What topics should be avoided;

• When to leave a discussion;

• How to document an objection;

• When to contact the legal department;

• How to handle documents received from competitors.

When Does a Distribution Agreement Become a Competition Issue?

A business may assume that competition law only regulates relationships between competitors.

That is incorrect.

Competition law can also affect vertical relationships, such as those between manufacturers and distributors or suppliers and retailers.

A distribution contract may contain provisions concerning:

• Territory;

• Customer groups;

• Online sales;

• Exclusivity;

• Non-compete obligations;

• Pricing;

• Promotion;

• Resale arrangements.

Whether a restriction creates a competition-law problem depends on its wording, commercial context, market position and the applicable Turkish rules.

Businesses should therefore consider competition law before signing the agreement, rather than waiting until a dispute arises.

This is particularly important for companies using standard contracts across several jurisdictions. A clause that is acceptable under one country's competition regime may require a different analysis in Türkiye.

Resale Pricing Deserves Careful Legal Review

Pricing provisions in distribution agreements can be particularly sensitive.

A supplier may legitimately wish to protect its brand, maintain service quality or coordinate marketing. But that commercial objective does not automatically justify every method of controlling the reseller's prices.

Companies should distinguish between:

• Recommended pricing;

• Maximum pricing;

• Fixed resale pricing;

• Discounts;

• Promotional restrictions;

• Indirect pricing controls.

The precise legal assessment depends on the arrangement and applicable competition rules.

The Turkish Competition Authority's guidelines and publications should be checked when evaluating current regulatory treatment.

Dominance Is Not the Same as Monopoly

Another common misunderstanding is that Turkish competition law prohibits companies from becoming dominant.

It does not work that way.

A company can become commercially successful, gain substantial market share and establish a strong competitive position without automatically violating competition law.

The concern arises when dominant position is abused.

Article 6 of Law No. 4054 addresses abuse of dominant position.

Potential examples may include certain forms of:

• Exclusionary conduct;

• Discriminatory treatment;

• Excessive or unfair conditions;

• Refusal to supply;

• Loyalty-inducing arrangements;

• Tying or bundling;

• Predatory or exclusionary pricing.

The analysis is highly dependent on the facts.

Why Market Definition Matters More Than Many Businesses Realize

Suppose a company sells a specialized product and appears to control 70% of its sales.

Does that automatically mean it is dominant?

Not necessarily.

Competition lawyers and economists may first need to determine what products actually compete with the company's offering.

The relevant market might be:

• Narrow or broad;

• Local, national or international;

• Product-specific or service-based;

• Traditional or digital.

Customer substitution is often important.

If customers can easily move from one product to another, the competitive constraint may be stronger than a simple market-share figure suggests.

This is one reason competition-law assessments should be based on the actual commercial environment rather than assumptions.

Merger Control Can Affect a Transaction Before Closing

Competition law also becomes highly relevant when one company proposes to acquire another.

A transaction can be commercially attractive and legally valid under company law while still requiring competition-law clearance.

The Turkish merger-control regime is principally based on Article 7 of Law No. 4054 and the applicable secondary legislation.

The Competition Authority provides official merger and acquisition resources, including legislation and regulatory materials.

Why Merger Analysis Should Start Early

Competition review should not necessarily be left until the transaction documents are almost finalized.

Early analysis can help determine:

• Whether notification is required;

• Whether Turkish turnover thresholds are met;

• How the relevant markets should be analysed;

• Whether the parties have overlapping activities;

• Whether competitors may be affected;

• Whether remedies could become relevant;

• How the transaction timetable should be structured.

The Turkish regime has undergone significant recent developments, so historical transaction assumptions should not be used without checking the current rules.

Technology Transactions Need Particular Attention

Technology acquisitions can present unusual competition questions.

The Competition Authority has been actively examining how digital transformation affects competition policy. In 2026, the Authority announced a new study focused on competition policy in the digital age, including data-driven business models, platforms and artificial intelligence.

Businesses involved in technology M&A should therefore consider competition issues alongside intellectual property, data protection, corporate and regulatory due diligence.

Digital Competition Is Becoming a Different Kind of Legal Problem

Digital markets do not always behave like traditional markets.

A digital platform may provide services for little or no monetary price while generating value through data, advertising or another side of a multi-sided market.

Competition analysis may consequently involve:

• User data;

• Network effects;

• Platform access;

• Algorithms;

• Ranking systems;

• Interoperability;

• Switching costs;

• Self-preferencing;

• Online advertising;

• Ecosystem effects.

The Turkish Competition Authority has expressly recognised that digital markets can make market definition, assessment of market power and identification of competitive harm more complex.

Artificial Intelligence and Competition Law

Artificial intelligence introduces another layer.

Businesses may use AI for:

• Pricing;

• Recommendations;

• Advertising;

• Customer segmentation;

• Procurement;

• Inventory management;

• Competitor monitoring.

The fact that an algorithm makes a decision does not automatically remove competition-law responsibility.

Companies should understand how their systems operate and whether automated decision-making could create coordination, exclusionary conduct or other competition concerns.

Competition Law and Online Advertising

Online advertising is a useful example of how competition law can intersect with technology.

Digital advertising frequently involves several sides of a market:

• Advertisers;

• Agencies;

• Publishers;

• Platforms;

• Technology providers;

• Consumers.

The Turkish Competition Authority announced in April 2026 that it had opened an investigation concerning Google's online advertising practices, including questions under Article 6 of Law No. 4054.

This illustrates why businesses operating in technology-driven markets should not assume that competition law is limited to traditional pricing or cartel scenarios.

What Happens When the Competition Authority Starts Looking at a Business?

A competition matter may begin with a complaint, market information, sectoral work, evidence obtained by the Authority or another regulatory development.

The first mistake a company should avoid is treating the matter as ordinary correspondence.

Preserve Relevant Information

Once a competition concern becomes apparent, relevant documents should be preserved.

Potentially relevant materials can include:

• Emails;

• Contracts;

• Presentations;

• Internal reports;

• Pricing documents;

• Sales information;

• Meeting records;

• Messages;

• Tender documents;

• Board materials.

Employees should never delete or alter potentially relevant evidence.

Establish One Internal Response Team

A company can quickly become disorganised when several departments respond independently.

A controlled response generally works better.

The business may designate:

• Internal legal counsel;

• External competition counsel;

• Compliance personnel;

• IT representatives;

• Relevant business executives.

This allows factual and legal information to be gathered systematically.

Do Not Guess in a Regulatory Response

Competition investigations can involve complex factual questions.

A response should be accurate and appropriately reviewed.

The objective is not to make the company appear innocent through overly broad statements. The objective is to provide a legally sound, factually accurate response.

What Is an On-Site Competition Investigation?

An on-site investigation can be one of the most stressful events for a business.

Employees may suddenly find officials requesting access to documents and electronic information.

The correct response is neither obstruction nor panic.

Businesses should have a written protocol explaining:

1. Who must be notified;

2. Who receives officials;

3. Who contacts external counsel;

4. How IT personnel respond;

5. How documents are preserved;

6. How employees should communicate;

7. How the investigation is documented.

The Turkish Competition Authority provides official information concerning its enforcement activities and competition-law framework.

A competition investigation protocol should ideally be prepared before an inspection takes place.

Competition Compliance Is More Than an Employee Handbook

A competition compliance program should not consist solely of a document that employees sign once a year.

An effective program should reflect the company's actual risk profile.

Sales Teams

Sales personnel may have frequent contact with competitors, distributors and customers.

They should understand the boundaries around:

• Competitor communications;

• Pricing;

• Customer allocation;

• Discounts;

• Distribution restrictions.

Procurement Teams

Procurement employees may interact with suppliers and competing bidders.

They should understand the risks of:

• Coordinated purchasing;

• Competitor information;

• Tender discussions;

• Sensitive market data.

Senior Management

Executives may participate in industry associations, strategic meetings and M&A negotiations.

Senior decision-makers should understand that competition-law risk can arise from informal discussions as well as formal agreements.

A Simple Competition Compliance Test for Employees

Before entering into a potentially sensitive conversation, an employee can ask:

Who am I speaking to?

If it is a competitor, proceed carefully.

What information am I discussing?

If it concerns future pricing, customers, capacity or strategy, stop and seek guidance.

Would I be comfortable if this conversation appeared in a regulatory investigation?

If the answer is no, the conversation deserves immediate legal review.

This is not a substitute for legal advice, but it can provide a practical first line of protection.

Why Competition Problems Are Often Discovered Through Documents

Competition investigations frequently involve documentary evidence.

A single email may appear harmless when viewed alone but become more significant when combined with:

• Meeting notes;

• Pricing documents;

• Internal messages;

• Competitor communications;

• Customer complaints;

• Tender records.

Businesses should therefore avoid casual language when discussing competitors.

Professional internal communication is not about hiding information. It is about recording business decisions accurately and avoiding speculative or misleading statements.

Competition Law and Commercial Contracts Should Be Connected

Competition law should not operate in isolation from commercial legal work.

A company negotiating a major supply agreement may need both:

• Contract-law analysis; and

• Competition-law analysis.

Likewise, an acquisition may involve:

• Corporate law;

• M&A;

• Competition law;

• Tax;

• Employment;

• Intellectual property;

• Data protection;

• Regulatory approvals.

This is why competition advice is often most effective when integrated into the wider transaction.

For businesses entering commercial arrangements in Türkiye, the Turkish Commercial Code and related commercial legislation may need to be considered alongside competition rules.

Competition Law and Intellectual Property Can Overlap

Intellectual property rights grant legally recognized exclusivity in particular circumstances.

Competition law asks a different question: whether the exercise of market power or contractual restrictions associated with those rights may harm competition.

Potential overlap can arise in:

• Technology licensing;

• Patent licensing;

• Software distribution;

• Brand licensing;

• Standard-essential technologies;

• Exclusivity arrangements;

• Technology transfer.

Businesses should therefore consider competition law when designing licensing arrangements that have substantial effects on a market.

The Turkish Patent and Trademark Office provides official information concerning intellectual property rights in Türkiye.

Competition Law Can Intersect With Data Protection

Modern businesses frequently use customer and business data to compete.

Competition law and data protection law are separate legal regimes, but commercial projects can require consideration of both.

For example, a digital platform may need to examine:

• Data access;

• Data sharing;

• Customer information;

• Platform governance;

• Market power;

• Privacy obligations.

The Personal Data Protection Authority of Türkiye provides official information concerning Türkiye's data-protection framework.

A business should not assume that compliance with one regulatory regime automatically resolves the other.

Competition Risk in Cross-Border Transactions

International businesses frequently face competition law in more than one jurisdiction.

A transaction involving a Turkish target may potentially require analysis in:

• Türkiye;

• The European Union;

• The United States;

• The United Kingdom;

• Other jurisdictions where the parties conduct business.

The Turkish analysis should therefore be integrated into the international transaction timetable.

The European Commission's competition policy portal provides useful official information concerning EU competition rules, while Turkish transactions require separate analysis under the applicable Turkish regime.

What Businesses Should Do Before Signing a Major Deal

Before signing a transaction or strategic agreement, management should consider a short competition-law screening.

For an Acquisition

Ask:

• Are the parties competitors?

• Do their businesses overlap?

• Are there vertical relationships?

• Are Turkish notification requirements triggered?

• Are technology or other specially relevant markets involved?

• Could the transaction affect competition in Türkiye?

For a Distribution Agreement

Ask:

• Is there exclusivity?

• Are territories restricted?

• Are customers allocated?

• Are online sales restricted?

• Are pricing provisions appropriate?

• Are non-compete provisions proportionate?

For a Competitor Collaboration

Ask:

• Why are the competitors cooperating?

• What information will be exchanged?

• What decisions remain independent?

• How long will the arrangement last?

• What markets are affected?

• Are the restrictions necessary?

These questions do not replace a formal legal assessment, but they can help identify when legal advice should be obtained.

Why Early Competition Advice Is Usually More Useful

Competition lawyers are most valuable before a company has committed itself to a problematic arrangement.

Early advice can allow a business to:

• Modify a contract;

• Change a transaction structure;

• Establish information barriers;

• Adjust a distribution model;

• Train employees;

• Prepare for regulatory notification;

• Create an investigation protocol.

Once a problematic agreement has been signed or an investigation has begun, the available options may be narrower.

A Practical Takeaway for Companies Operating in Türkiye

Competition law should not be viewed as something that concerns only giant corporations.

A small or medium-sized business can encounter competition-law issues through a distribution agreement. A growing company can encounter them during an acquisition. A sales manager can encounter them during a conversation with a competitor. A technology company can encounter them through its platform design.

The safest approach is not to avoid commercial competition.

It is to understand the legal boundaries before making decisions that affect how competition works in the market.

Businesses operating in Türkiye should particularly pay attention to:

• Competitor communications;

• Sensitive commercial information;

• Distribution restrictions;

• Pricing arrangements;

• Market power;

• Mergers and acquisitions;

• Joint ventures;

• Tender processes;

• Digital platforms;

• Technology transactions;

• Competition compliance.

The Turkish Competition Authority's continuing enforcement activity demonstrates that competition law remains a practical business issue rather than a theoretical field. Recent decisions include investigations involving alleged price coordination and sensitive-information exchange, while digital markets and online advertising remain areas of regulatory attention.
