When to Notify a Joint Venture in Turkey (2026): Practical Guide for Investors, JV Partners & In‑house Counsel

Joint venture notification in Turkey has entered a new era following the publication of Communiqué No. 2026/2, which raised merger control thresholds and introduced clearer tests for technology undertakings and joint-venture assessment criteria. For in-house counsel, private equity deal teams and JV partners structuring cross-border transactions that touch the Turkish market, the practical question has shifted from whether Turkey has a meaningful filing regime to exactly when a planned JV triggers a mandatory Rekabet Kurulu notification. This guide walks through the updated legal tests, provides a filing-evidence checklist, maps procedural timelines from submission to clearance, and offers sector-specific scenarios so transaction teams can make confident go/no-go decisions before signing.

Executive Summary, Quick Decision Tree

A joint venture must be notified to the Turkish Competition Authority (Rekabet Kurumu) whenever two conditions are met simultaneously: the transaction qualifies as a concentration under Law No. 4054, and the parties exceed the applicable turnover thresholds set out in Communiqué No. 2026/2. If either condition is absent, no filing is required. The decision tree below distils the analysis into three gateway questions.

Quick checklist, 3 questions to decide on joint venture notification in Turkey:

1. Does the JV create a full-function entity or result in the acquisition of joint control? If yes, the transaction is likely a concentration. Proceed to question 2. If neither applies, the arrangement is typically a cooperation agreement outside merger control.
2. Do the parties’ turnovers in Türkiye (or globally, depending on the test) exceed the thresholds in Communiqué No. 2026/2? If yes, proceed to question 3. If no, the transaction falls below the filing triggers.
3. Is any party a technology undertaking with limited Turkish turnover but significant user reach or data access in Türkiye? If yes, the revised technology-undertaking criteria may still capture the transaction even where traditional turnover tests appear unmet.

If the answer to questions 1 and 2 (or 1 and 3) is “yes,” the JV must be notified before closing. Failure to notify carries administrative fines and the risk that the Turkish Competition Board (Rekabet Kurulu) may order an unwinding of the transaction.

What Changed in 2026? Communiqué No. 2026/2 Explained

Communiqué No. 2026/2, published in the Official Gazette (T.C. Resmî Gazete) in early 2026, represents the most significant update to Turkey’s pre-merger notification framework in several years. The amendments respond to two converging pressures: inflation-driven obsolescence of earlier TRY-denominated thresholds, and the growing influence of digital-economy transactions that traditional turnover metrics struggle to capture.

Key Changes at a Glance

The communiqué introduced three principal modifications relevant to joint venture notification in Turkey:

• Higher turnover thresholds. Both the aggregate Turkish-market turnover threshold and the individual-party turnover threshold were raised to reflect current economic conditions. The updated figures mean that smaller JVs that would previously have required filing now fall below the notification line, reducing the compliance burden on mid-market deals.
• Technology-undertaking criteria. Communiqué No. 2026/2 formalises a test for technology undertakings, entities whose Turkish turnover is low but whose user base, data access or platform integration in Türkiye is significant. This mirrors international trends observed in the OECD’s work on merger control and digital markets and ensures that data-rich JVs cannot avoid scrutiny simply because they have not yet monetised their Turkish operations.
• Refined JV assessment criteria. The communiqué clarifies the factors the Rekabet Kurulu will weigh when deciding whether a JV is “full-function”, specifically, the duration of activity, resource independence, and market-facing operations, reducing ambiguity that had prompted inconsistent self-assessments by filing parties.

Timeline of 2026 Changes

Legal Framework and Who Decides, Law, Thresholds and Authority

Turkey’s merger control regime rests on Law No. 4054 on the Protection of Competition, specifically Article 7, which prohibits mergers and acquisitions that create or strengthen a dominant position so as to significantly reduce competition. The Rekabet Kurulu, the decision-making board of the Turkish Competition Authority, is the sole body empowered to review and clear (or block) notifiable transactions, including joint ventures.

Notification Triggers, Legal Basis

Filing Party Responsibility and Joint Filings

Where a JV involves the creation of a new entity, all parent undertakings acquiring joint control are responsible for submitting a competition board notification. In practice, parties usually file jointly through a single counsel to avoid inconsistencies in the data presented to the Rekabet Kurulu. If one party refuses to cooperate in the filing, the other may submit a unilateral notification, but must explain the circumstances and provide as much counterparty information as is reasonably available.

Joint Venture Notification Tests, Full‑Function JV vs. Other Cooperation

Not every joint arrangement between competitors or vertical partners constitutes a notifiable concentration. The critical distinction under Turkish merger control is between a full-function joint venture, which is treated as a concentration, and a cooperation agreement that falls outside the merger filing regime (though it may still be assessed under the cartel or restrictive-agreement provisions of Law No. 4054).

Full‑Function JV: Indicators and Examples

A joint venture qualifies as full-function when it performs, on a lasting basis, all the functions of an autonomous economic entity. The Rekabet Kurulu looks at several practical indicators:

• Sufficient resources. The JV has its own management, staff, assets and funding to operate independently in the market.
• Market presence. The JV sells goods or services to third parties, not exclusively to its parent undertakings.
• Duration. The JV is intended to operate on a lasting basis, typically indefinitely or for a period long enough to bring about a lasting change in market structure.

A typical example is two infrastructure companies forming a new entity to build and operate a fibre-optic network serving commercial customers in Türkiye. The JV has its own team, secures third-party contracts, and is designed to operate for decades.

Acquisition of Joint Control, How to Spot It

Joint control exists when two or more parent undertakings share the ability to exercise decisive influence over the JV’s strategic commercial decisions, typically through equal voting rights, veto powers over the budget or business plan, or the right to appoint key management. Even a minority shareholder can hold joint control if the governance arrangements confer genuine blocking rights.

When Extraterritorial JVs Trigger Joint Venture Notification in Turkey

Foreign-to-foreign JVs with no Turkish subsidiary may still require a Rekabet Kurulu notification if the parent undertakings generate turnover in Türkiye that exceeds the thresholds. Turnover is attributed based on sales to customers located in Türkiye, regardless of where invoicing or delivery occurs. Industry observers expect the Competition Board to apply these attribution rules more rigorously under the revised communiqué, particularly where digital services are involved.

Technology Undertakings: What Changed and Practical Test Cases

Communiqué No. 2026/2 addresses an emerging gap: technology undertakings that accumulate large user bases or strategic data access in Türkiye without generating significant Turkish turnover. Under the revised rules, such entities may be caught by the notification regime if the transaction meets the technology-undertaking criteria, factors that include active user numbers, data volumes processed in Türkiye, and integration with local digital ecosystems. Early indications suggest the TCA will scrutinise JVs involving platform-to-platform data sharing, API access grants, and ad-tech integrations with particular care.

Reporting Obligations by JV Type

Preparing the Filing, Evidence Checklist and Documentary Pack

A well-prepared filing accelerates the Rekabet Kurulu review and reduces the risk of information requests that can delay clearance by weeks. The checklist below reflects the documentary requirements derived from TCA notification forms and filing guidance.

Mandatory Documents

• Completed notification form. The prescribed TCA form, signed by authorised representatives of all filing parties.
• Corporate documents. Certificates of incorporation, articles of association, and current shareholder registers for each parent undertaking and the JV entity (or draft formation documents if the JV is not yet incorporated).
• Powers of attorney. Notarised and apostilled (if foreign) authorisation for counsel to file on the parties’ behalf.
• Audited financial statements. Consolidated and (where relevant) Turkish-entity financials for the most recent two financial years, showing turnover breakdowns by geography.
• JV agreement. Executed or final-form joint venture agreement, shareholders’ agreement, and any side letters governing governance, veto rights and exit provisions.

Market and Competition Evidence

• Market share data. Estimates of the parties’ shares in all relevant product and geographic markets, supported by third-party reports, industry association data, or internal sales analyses.
• Competitor landscape. Identification of the top competitors, their estimated shares, and recent market entry or exit events.
• Customer and supplier contracts. Material contracts that illustrate the parties’ existing market positions, particularly any exclusivity, most-favoured-nation or long-term supply arrangements.
• Pricing data. Representative pricing information for key products or services in Türkiye.

For Technology JVs: User Metrics, APIs and Data Access Evidence

Where one or more parties qualifies as a technology undertaking, the filing should additionally include:

• Active user counts in Türkiye (monthly and daily active users).
• Data volumes processed, stored or transferred through Turkish-based infrastructure.
• API documentation and data-sharing protocols between the JV and the parent platforms.
• Revenue attribution methodologies if Turkish turnover is indirect (e.g., ad-tech revenue allocated by user geography).

Common Filing Mistakes to Avoid

• Incomplete turnover calculations. Failing to include group-wide Türkiye turnover for each parent undertaking, the TCA calculates on a consolidated basis.
• Missing translations. All foreign-language documents must be accompanied by certified Turkish translations; incomplete translations cause immediate delays.
• Vague market definitions. Submitting overly broad or unsupported market definitions invites additional information requests and can extend the review timeline.
• Ignoring technology-undertaking criteria. Parties that dismiss the new technology tests without analysis risk an incomplete filing or a post-closing enforcement action.

JV Notification Checklist, Sample Filing Bundle

Procedural Timeline and Practical Milestones, Filing to Clearance

Turkey does not impose a fixed statutory deadline by which parties must file, but the transaction may not be closed before clearance is obtained. In practice, filing promptly after signing (or even during negotiations via a pre-notification approach) is the safest route.

Timeline from Filing to Clearance

Fast-Track Possibilities and Suspension Obligations

Straightforward JVs in unconcentrated markets that clearly fall within Phase I parameters can expect clearance within approximately 30 days. The critical obligation to bear in mind is the standstill requirement: the JV must not commence operations, and the parties must not integrate competitively sensitive functions, until the Rekabet Kurulu issues its clearance. Violations of the standstill rule carry separate administrative penalties under Law No. 4054.

Remedies, Commitments and Negotiating with the TCA

Where the Competition Board identifies competition concerns in a JV notification, it may clear the transaction subject to conditions, known as remedies or commitments. Understanding the types of remedies the TCA has historically imposed helps deal teams structure the JV proactively to minimise remedy risk.

Typical Remedies in Turkish JV Clearances

• Behavioural remedies. Requirements to maintain open access, non-discrimination obligations, information-wall protocols between the JV and parent undertakings, or limits on the scope of commercial cooperation outside the JV’s core activity.
• Structural remedies. Divestiture of overlapping assets or business lines, termination of existing exclusive distribution arrangements, or restrictions on the JV’s geographic scope within Türkiye.
• Ancillary restraint carve-outs. Limitations on non-compete clauses between the parents and the JV, the TCA applies strict proportionality tests to the duration and scope of ancillary restraints.

Drafting Tips for Remedy Negotiation

Industry observers expect the TCA to continue favouring behavioural remedies for JVs where competitive harm is conduct-based rather than structural. Deal teams can reduce remedy exposure by pre-emptively including information-barrier clauses, third-party access commitments and sunset provisions in the JV agreement itself, demonstrating to the Competition Board that the parties have addressed potential concerns before the review even begins.

Sector Examples, Telecoms, Healthcare, Digital Platforms

Telecom / Infrastructure JV

Two mobile operators forming a network-sharing JV to deploy 5G infrastructure in rural Türkiye. The JV has its own management team, procures equipment independently, and sells wholesale access to third-party operators. This is a classic full-function JV. Both parents exceed Turkish turnover thresholds. The notification will need to include spectrum-licence details, network-coverage maps and wholesale pricing commitments to address potential access concerns.

Healthcare JV

A multinational pharmaceutical company and a Turkish hospital group create a JV to operate diagnostic imaging centres across several provinces. The JV employs its own clinical staff and contracts directly with patients and insurers. Joint control is established through equal board representation and mutual veto rights over the annual budget. The filing will require market-share data for diagnostic imaging services at the provincial level, patient volumes and referral-pathway evidence.

Digital Platform / Technology JV (Technology Undertakings in Turkey)

Two global platform companies, one in ride-hailing, the other in food delivery, form a JV to develop a “super app” for Turkish urban markets. Neither generates substantial Turkish advertising revenue directly, but both have millions of monthly active users in Türkiye and process significant volumes of location and transaction data locally. Under the technology-undertaking criteria introduced by Communiqué No. 2026/2, the JV is likely notifiable despite low traditional turnover. The filing must include Turkish user metrics, data-flow architecture, API integration plans and evidence on how the combined data set could affect adjacent markets.

Risk Scenarios and Negotiation Playbook

Deal teams should map their transaction against a simple risk matrix before signing to ensure the joint venture agreement contains adequate protections for the notification period.

Pre-Closing Steps and Fallback Planning

• Condition precedent clause. The JV agreement should make closing conditional on obtaining Rekabet Kurulu clearance (unconditional or on terms acceptable to the parties).
• Long-stop date. Include a realistic long-stop date, typically 6 to 9 months from signing, that accounts for the possibility of a Phase II review.
• Escrow arrangements. Where capital contributions are made at signing, hold funds in escrow pending clearance to avoid standstill-rule complications.
• Reverse break fee. Consider whether a reverse break fee is appropriate if clearance is denied or unacceptable conditions are imposed, particularly where one party bears more regulatory risk than the other.
• Information-barrier protocol. Implement a clean-team or information-barrier protocol from signing to clearance to prevent the premature exchange of competitively sensitive information between the parent undertakings.

Practical Next Steps

Transaction teams evaluating joint venture notification in Turkey should take the following steps immediately:

• Run the three-question self-assessment. Apply the decision tree in the executive summary to determine whether notification is likely required.
• Calculate consolidated turnover. Obtain group-wide Türkiye turnover figures for each parent undertaking on a consolidated basis, not just the direct party to the JV.
• Assess technology-undertaking exposure. If any party operates a digital platform, processes Turkish user data, or integrates via APIs with local services, apply the Communiqué No. 2026/2 technology criteria.
• Assemble the filing bundle early. Use the checklist above to begin gathering documents at the term-sheet stage; this prevents last-minute delays after signing.
• Draft protective contractual provisions. Ensure the JV agreement includes a clearance condition precedent, a realistic long-stop date, an information-barrier protocol, and appropriate break-fee mechanics.
• Consider pre-notification engagement. For complex transactions or those involving horizontal overlaps, approaching the TCA informally before filing can flag issues early and shorten the formal review timeline.
• Seek specialist counsel. Turkish merger control involves jurisdiction-specific procedural requirements, and errors in self-assessment can carry significant financial and operational consequences.
