Mergers and acquisitions (M&A) transactions in Turkey operate within a framework combining the Turkish Commercial Code No. 6102 Articles 136-194 (merger provisions at Articles 136-158, demerger provisions at Articles 159-179, and conversion provisions at Articles 180-194), Competition Law No. 4054 Articles 7 and 10 governing merger control, Communiqué No. 2010/4 Concerning Mergers and Acquisitions Requiring Competition Board Authorization (published in Official Gazette No. 27722 on 7 October 2010) as amended by Communiqué No. 2022/2 (Official Gazette No. 31768 of 4 March 2022, effective 4 May 2022) and further amended by Communiqué No. 2026/2 (Official Gazette No. 33165 of 11 February 2026), Corporate Tax Law No. 5520 including Article 19 tax-free merger and demerger provisions, Value Added Tax Law No. 3065 Article 17/4(c) share transfer exemption, Turkish Code of Obligations No. 6098 for contract framework, Labor Law No. 4857 Article 6 for employment continuity in asset and merger transactions, MASAK Law No. 5549 for anti-money-laundering source-of-funds requirements, sector-specific regulations for regulated industries, and International Arbitration Law No. 4686 for arbitration governance. Merger control notification thresholds under the current framework established by Communiqué No. 2022/2 require notification where combined Turkish turnover of the parties exceeds TRY 750 million and at least one party has Turkish turnover exceeding TRY 250 million (Article 7(1)(a) test) or where the transferred undertaking's Turkish turnover exceeds TRY 250 million and the acquirer's worldwide turnover exceeds TRY 3 billion (Article 7(1)(b) test), with Communiqué No. 2026/2 of 11 February 2026 raising these thresholds and introducing special provisions for technology undertakings (digital platforms, software, fintech, biotech, pharmaceuticals, agrochemicals, health technology) that remain subject to lower thresholds. Practice may vary by authority and year, and M&A transactions in Turkey benefit from integrated legal, tax, and strategic coordination rather than sequential treatment. A lawyer in Turkey coordinates the framework elements determining whether M&A transactions achieve both immediate deal success and long-term value realization. For framework on mergers and acquisitions specifically for foreign investors, readers can consult our M&A legal process guide for foreign investors.
Statutory framework for M&A transactions in Turkey
A Turkish Law Firm advising on M&A transactions works from the statutory framework that determines the available transaction structures and governing provisions. Merger transactions under TTK Articles 136-158 operate through universal succession (külli halefiyet) where the acquiring company (devralan şirket) takes over all assets, liabilities, rights, and obligations of the merging company (devralınan şirket) through operation of law upon Trade Registry registration — this universal succession mechanism provides transactional efficiency through single-act transfer of the entire undertaking without need for individual asset or contract assignments. Merger forms include merger by absorption (devralma yoluyla birleşme) where an existing company absorbs another existing company that ceases to exist, and merger by formation of new company (yeni kuruluş yoluyla birleşme) where two or more companies combine into a newly formed entity with the combining companies ceasing to exist. Merger eligibility under Article 137 permits mergers between capital companies (A.Ş., Ltd. Şti.), cooperatives, and certain partnerships, while some cross-form mergers require approval framework. Merger protection under Articles 140-148 requires exchange ratio determination with valuation report, auditor review where applicable, merger agreement (birleşme sözleşmesi) with specific required content, general assembly approvals with qualified majority, and shareholder protection through Articles 152 and 153 including right to claim cash payment in certain circumstances. Practice may vary by authority and year, and merger transaction structuring requires specific legal review at each stage.
Turkish lawyers who address demerger transactions work through TTK Articles 159-179 framework covering full demerger (tam bölünme) where a company divides into multiple successor companies and partial demerger (kısmi bölünme) where a portion of a company transfers to one or more existing or newly formed companies. Demerger operates through partial universal succession for the transferred portion — the successor company or companies take over the specified assets, liabilities, and contractual relationships proportionally or as designated in the demerger agreement (bölünme sözleşmesi or bölünme planı). Tax-free demerger conditions under Corporate Tax Law No. 5520 Article 19 require that the transferred assets constitute an active business line (faaliyet kolu) with associated assets and liabilities, that shares in the successor company are distributed proportionally to the shareholders of the divided company, and that minimum holding periods and activity continuation requirements are met. Failure to meet tax-free conditions triggers tax recognition on the transaction with significant tax cost consequences. Conversion transactions under TTK Articles 180-194 permit company form changes (for example A.Ş. to Ltd. Şti. or vice versa) with continuity of legal personality — the converted company is the same legal entity in different form rather than a new entity through succession. Practice may vary by authority and year, and demerger and conversion structuring benefits from integrated tax and corporate planning.
An Istanbul Law Firm coordinating acquisition alternatives outside merger and demerger mechanics works through the framework of share acquisition, asset acquisition, and joint venture structures. Share acquisition (pay devri) where the acquirer purchases outstanding shares of the target company provides the most common M&A transaction structure — the target company continues as a legal entity with new ownership, all assets and liabilities remain with the target, and the transaction completes through share transfer mechanics without disruption to the target's operations, contracts, or licenses (subject to change-of-control provisions in the target's agreements). Share acquisition framework differs for A.Ş. shares (registered nama shares with share certificates or uncertified shares under Trade Registry ledger, bearer hamiline shares with Trade Registry notification requirement under Law No. 7262) versus Ltd. Şti. quotas (requiring notarial share transfer agreement and general assembly approval under TTK Article 595). Asset acquisition (varlık devri) where the acquirer purchases specified assets and assumes selected liabilities provides greater selectivity but requires individual asset transfers, contract novations, employee transfers, and regulatory re-licensing where applicable. Joint venture structures through ortaklık agreements or dedicated joint venture entities provide collaboration framework with shared governance and specific exit arrangements. Each structure carries distinct tax treatment, regulatory implications, and operational consequences. For framework on asset purchase transactions, readers can consult our asset purchase agreement guide.
Due diligence architecture and red-flag analysis
A lawyer in Turkey coordinating due diligence for M&A transactions works through the integrated verification framework covering legal, financial, tax, employment, regulatory, intellectual property, and environmental categories. Legal due diligence addresses corporate governance (articles of association, general assembly and board resolutions, shareholder agreements, board composition), share capital structure (paid capital, capital increases history, share classes and rights), shareholding verification (Trade Registry records, share ledger, pledges or attachments on shares), material contracts (customer agreements, supplier contracts, distribution arrangements, technology licenses, financing agreements with change-of-control provisions), real estate (ownership, encumbrances, lease arrangements), litigation (pending cases, threatened claims, arbitration proceedings, regulatory investigations), and regulatory compliance (licenses, permits, sector-approvals). Financial due diligence through qualified accountants addresses audited and unaudited financial statements, management accounts, cash flow analysis, quality of earnings, working capital, debt structure, and financial reporting integrity. Tax due diligence covers corporate income tax compliance, VAT reporting, withholding tax obligations, transfer pricing documentation, tax disputes and audit history, and potential exposures from aggressive positions or transaction structures. Practice may vary by authority and year, and due diligence discipline determines whether transactions proceed on informed basis.
Turkish lawyers who address employment due diligence work through the framework identifying workforce-related risks and obligations. Employment contract review addresses standard employment terms, senior management arrangements (service contracts, stock option plans, non-compete provisions, severance arrangements), collective bargaining agreements where unionized workforce exists, and benefit arrangements. Labor dispute history includes pending labor court cases, İş Mahkemeleri compulsory mediation records (since 1 January 2018), previous employee claims and settlements, and regulatory inspections from İş Müfettişliği (Labor Inspection). Severance liability calculation under Labor Law No. 4857 Article 17 and Mülga 1475 Article 14 (continuing in force for severance) addresses accrued severance obligations that would become payable upon termination — acquirers often insist on escrow or purchase price adjustment for undisclosed severance exposures. Social Security (SGK) compliance verifies workplace registration, employee declarations, contribution payments, and potential retroactive liability for misclassification or underreporting. Work permit (çalışma izni) status for foreign employees under Law No. 6735 addresses whether necessary permits are current and properly maintained. For framework on employment risk specifically in acquisitions, readers can consult our commercial litigation guide. Practice may vary by authority and year.
An English speaking lawyer in Turkey coordinating regulatory and intellectual property due diligence works through the framework addressing sector-specific and proprietary asset considerations. Regulatory due diligence for companies in regulated sectors verifies current license status, license conditions and restrictions, pending regulatory matters or investigations, compliance with sector-specific obligations, and whether proposed transaction triggers regulatory approvals. Banking sector transactions require BDDK (Banking Regulation and Supervision Agency) approval under Banking Law No. 5411 with ownership change framework and fit-and-proper assessment. Energy sector transactions require EPDK (Energy Market Regulatory Authority) approval under sector-specific laws (Electricity Market Law No. 6446, Petroleum Market Law No. 5015, Natural Gas Market Law No. 4646, Electricity Distribution Law) with license transfer and change-of-control assessments. Capital markets transactions involving publicly traded companies require SPK (Capital Markets Board) compliance under Capital Markets Law No. 6362 including mandatory tender offer framework. Electronic communications transactions require BTK (Information and Communication Technologies Authority) approval under Electronic Communications Law No. 5809. Intellectual property due diligence addresses trademark, patent, design, copyright, trade secret, and domain name ownership with verification of proper registration and assignment chain, challenges or oppositions, and licensing arrangements including change-of-control clauses. Data protection compliance under KVKK Law No. 6698 addresses personal data processing activities, VERBİS registration, data breach history, and transfer mechanisms. Practice may vary by authority and year, and specialized due diligence for regulated sectors requires sector-expertise beyond standard legal review.
Transaction structure selection and negotiation framework
A Turkish Law Firm coordinating transaction structure selection works through the framework matching structural architecture to commercial, legal, tax, and operational objectives. Share transaction structure (pay devri) provides continuity of the target company with change of ownership — advantages include transaction simplicity (single transfer document for A.Ş. shares or notarial agreement for Ltd. Şti. quotas, subject to change-of-control provisions in target's contracts), preservation of target's contracts and licenses without novation requirements (though change-of-control provisions in contracts may require consents), and tax efficiency for individual sellers through five-year holding exemption under Income Tax Law No. 193 Article 80. Disadvantages include acquirer assumption of all target liabilities (known and unknown), succession to target's tax history and pending disputes, and limited ability to select what is acquired. Asset transaction structure (varlık devri) provides selective acquisition of specified assets and liabilities — advantages include ring-fencing from historical liabilities, selectivity on what transfers, and tax treatment in some circumstances. Disadvantages include complexity of individual asset transfers, contract novation requirements for non-assignable agreements, employment continuity obligations under Labor Law Article 6 for transferred workforce, and re-licensing requirements for regulated activities. Practice may vary by authority and year, and structure selection benefits from integrated analysis of risk allocation, tax treatment, operational continuity, and transaction efficiency.
Turkish lawyers who address term sheet and pre-contractual negotiation work through the framework establishing deal architecture before definitive documentation. Letter of Intent (LOI) or Memorandum of Understanding (MOU) documents the parties' preliminary understanding on key commercial terms — typical content includes purchase price or pricing mechanism, payment structure, transaction structure, conditions precedent categories, exclusivity arrangements, due diligence framework, confidentiality obligations, target closing timeline, and binding versus non-binding characterization of provisions. Exclusivity (no-shop) provisions protect the buyer's investment in transaction preparation by preventing the seller from negotiating with alternative buyers during a specified period. Non-disclosure agreements (NDAs) under TBK framework protect confidential information shared during negotiation — NDA terms address scope of confidential information, permitted uses, return or destruction at transaction termination, duration of obligations, and remedies for breach. Exclusivity breakup fees and expense reimbursement provisions address consequences if specific parties terminate the transaction under circumstances. For framework on NDA drafting specifically, readers can consult our NDA drafting guide. Practice may vary by authority and year, and pre-contractual discipline protects both parties' interests during the negotiation phase.
An Istanbul Law Firm addressing negotiation dynamics for cross-border M&A works through the framework that accounts for Turkish legal requirements alongside international transaction practice. International transaction practice often imports concepts from English or US M&A markets including detailed representations and warranties, specific indemnification frameworks, material adverse change (MAC) provisions, and specific closing mechanics — Turkish law enforces these provisions subject to Turkish Code of Obligations (TBK) No. 6098 framework with adjustments where Turkish mandatory provisions differ from international standards. Governing law selection for the main transaction documents often specifies Turkish law for Turkish-situated company shares (as Turkish corporate law governs Turkish company shares), while ancillary commercial agreements may select alternative governing law. Forum selection for disputes frequently favors international arbitration over Turkish courts for cross-border transactions with neutrality and enforceability considerations. Language selection typically produces bilingual documentation with Turkish-language version required for Turkish filings and English-language version for international operational use, with priority language designation addressing interpretation conflicts. Cultural and practice differences between Turkish and foreign M&A traditions may require adjustments in negotiation approach, timing expectations, and closing mechanics. Practice may vary by authority and year, and cross-border transaction coordination requires counsel with both Turkish legal capacity and international practice fluency.
Share Purchase Agreement drafting and post-closing protections
A lawyer in Turkey coordinating Share Purchase Agreement (SPA) drafting works through the framework integrating Turkish legal requirements with international SPA architecture. Representations and warranties (R&W) constitute a fundamental SPA element where the seller makes factual statements about the target's condition — categories include fundamental representations (capacity, authority, title to shares) typically with uncapped indemnity, general representations (financial statements, compliance with laws, material contracts, litigation, employment, tax, intellectual property) with caps and time limits, and business representations (product quality, customer relationships, operational matters) with negotiated limitations. Time limits on representations typically distinguish fundamental representations (often indefinite or long survival period), tax representations (until applicable tax statute of limitations expires, typically 5+ years), and general representations (negotiated survival typically 12-24 months). Materiality qualifiers including "material adverse effect" definitions, de minimis thresholds (individual claim minimum), and basket thresholds (aggregate claim minimum before recovery) protect against claims for immaterial breaches. Specific indemnities for identified risks through due diligence receive specific coverage outside general indemnity framework — unlike representations which protect against unknown issues, indemnities protect against known specific exposures. For framework on SPA drafting specifically, readers can consult our share purchase agreement drafting guide. Practice may vary by authority and year.
Turkish lawyers who address purchase price mechanics work through the framework determining final consideration and adjustment mechanisms. Fixed purchase price provides certainty but requires accurate target valuation at signing — typically used for stable businesses with limited volatility. Locked box mechanism uses a reference balance sheet date (often several months before signing) with the purchase price calculated based on that date's financial position and seller providing leakage protections (no value leakage between reference date and closing) — advantages include certainty and simplicity, disadvantages include buyer exposure to business developments between reference date and closing. Completion accounts mechanism determines final purchase price based on closing-date financial position with working capital, cash, and debt adjustments — advantages include buyer protection against post-signing value changes, disadvantages include post-closing negotiation risk over completion accounts. Earnout provisions condition a portion of purchase price on post-closing performance (typically EBITDA, revenue, or specific milestone achievement) over a defined measurement period — earnouts bridge valuation gaps between buyer and seller but create post-closing operational and dispute management challenges. Deferred payment with escrow protection holds portions of purchase price in escrow pending completion of conditions or as indemnity security. Practice may vary by authority and year, and price mechanics structure significantly affects risk allocation between buyer and seller.
An English speaking lawyer in Turkey addressing closing conditions and covenants works through the framework governing the gap period between signing and closing. Conditions precedent (ön şartlar) establish requirements that must be satisfied before closing obligations arise — typical categories include regulatory approvals (Competition Authority clearance, sector-approvals), governance approvals (target and acquirer board and shareholder approvals where required), third-party consents (key customer or supplier change-of-control consents), due diligence completion satisfactory to the buyer, no material adverse change in the target's business, absence of governmental or judicial prohibitions, and other conditions tailored to the transaction. Interim covenants restrict or require specific seller and target behavior between signing and closing — restrictions on extraordinary transactions, capital changes, material contract modifications, specific personnel decisions, asset dispositions, and other matters protect the transaction's assumptions. Information covenants require periodic reporting by seller to buyer on business developments during the interim period. Closing mechanics address simultaneous exchange of purchase price, share transfer documents, director and officer resignations, updated company documentation, and other closing deliverables. Escrow arrangements supporting indemnity obligations secure a portion of purchase price against post-closing indemnity claims. For framework on escrow arrangements, readers can consult our escrow accounts guide. Practice may vary by authority and year.
Merger control under Competition Law No. 4054 and notification thresholds
A Turkish Law Firm coordinating merger control analysis works from the statutory framework under Competition Law No. 4054 (Rekabetin Korunması Hakkında Kanun) Article 7 defining mergers and acquisitions subject to competition assessment and Article 10 requiring pre-closing notification of qualifying transactions. Communiqué No. 2010/4 Concerning Mergers and Acquisitions Requiring Authorization by the Competition Board (published in Official Gazette No. 27722 on 7 October 2010) establishes the detailed notification and assessment framework — Article 5 defines covered transactions including mergers of previously independent undertakings, acquisition of control through purchase of shares or assets, and joint ventures creating full-function independent undertakings. Control under Article 5 means the ability to exercise decisive influence over an undertaking through rights, contracts, or other means — control includes sole control and joint control arrangements with multiple parties exercising joint decisive influence. Permanent change of control triggers notification obligation; temporary or purely internal restructurings generally fall outside merger control scope. Turnover threshold tests under Article 7 as amended by Communiqué No. 2022/2 (Official Gazette No. 31768 of 4 March 2022, effective 4 May 2022): the Article 7(1)(a) test applies where combined Turkish turnover of the parties exceeds TRY 750 million and Turkish turnover of at least one party exceeds TRY 250 million; the Article 7(1)(b) test applies where the Turkish turnover of the transferred undertaking (in acquisitions) or Turkish turnover of at least one party (in mergers) exceeds TRY 250 million and the worldwide turnover of at least one other party exceeds TRY 3 billion. Practice may vary by authority and year, and threshold analysis benefits from specific turnover calculation review.
Turkish lawyers who address the Communiqué No. 2026/2 amendments (Official Gazette No. 33165 of 11 February 2026) work through the updated framework further raising turnover thresholds and establishing special provisions for technology undertakings. The 11 February 2026 amendment increased the baseline thresholds reflecting inflation and policy considerations, with current specific threshold figures requiring review of the Communiqué No. 2026/2 text directly — practitioners should verify current thresholds at the time of transaction assessment because Communiqué amendments occur periodically. Technology undertakings under the Communiqué No. 2026/2 framework (following Communiqué No. 2024/2 introduction of technology undertaking concept) operate under lower notification thresholds reflecting the Turkish Competition Authority's policy to closely monitor concentration in technology markets. Technology undertakings include digital platforms, software companies, fintech providers, biotechnology and pharmaceutical undertakings, agrochemical producers, and health technology businesses. The lower technology thresholds mean that transactions involving these undertakings may be notifiable even where conventional turnover levels would be below standard thresholds, requiring assessment of the transferred undertaking's activity classification. Turnover calculation under Article 8 includes the relevant undertaking and connected undertakings under specific control relationships — the calculation is not limited to the transaction parties' standalone turnover but extends to the broader undertaking group. Practice may vary by authority and year, and technology undertaking analysis requires careful characterization review for transactions.
An Istanbul Law Firm addressing notification procedure and substantive review works through the procedural framework governing merger control approval. Notification is made through Form A (notification form) with required supporting documents including transaction agreement (final or current draft), corporate documentation of the parties, turnover documentation, market analysis for relevant markets, and other substantive information. Joint notification by the parties using a single Form A is typical for most transactions. Pre-notification consultation with the Competition Authority is available for complex cases to align expectations on information requirements. Preliminary review under Article 10 provides 15 days from complete notification submission for the Authority to conduct initial assessment — at preliminary review, the Authority either authorizes the transaction, initiates final review, or determines that the transaction does not require authorization. Final review when initiated involves comprehensive market analysis, third-party consultation where appropriate, and substantive assessment of competitive effects. Deemed approval under Article 10 applies where the Authority does not issue a decision within 30 days of complete notification — absent Authority action, the transaction is deemed approved and acquires legal validity. Suspensive effect means that notifiable transactions cannot be implemented before authorization (either explicit or deemed) — gun-jumping (implementing before clearance) creates significant financial penalties and transaction validity consequences. Remedies in cases where competitive concerns arise include structural remedies (divestment of specific business lines), behavioral remedies (commitments on conduct), and other tailored conditions. Practice may vary by authority and year, and merger control compliance benefits from early assessment and proactive filing coordination.
Tax architecture for M&A transactions
A lawyer in Turkey coordinating tax architecture for M&A transactions works through the framework covering acquisition, holding, integration, and exit phases with coordinated treatment across multiple tax categories. Share transaction tax treatment for individual sellers under Income Tax Law No. 193 Article 80 provides exemption for share sales where the seller held the shares for more than two years (unlisted company shares) or where sold through Borsa İstanbul for listed shares with specific holding period rules — the exemption applies to non-business individual holdings. Corporate seller tax treatment subjects share sale gains to corporate income tax at the standard 25% rate effective 1 January 2024 (increased from 23% under Law No. 7456 of 15 July 2023), with the 75% participation exemption under Corporate Tax Law No. 5520 Article 5/1-e available for sale of shares held for more than two years in qualifying Turkish subsidiaries (reducing effective tax on gain to 25% on 25% of the gain, or 6.25% effective rate). Withholding tax at source for non-resident seller share sales under circumstances requires Turkish buyer or paying agent withholding. Value Added Tax Law No. 3065 Article 17/4(c) exemption provides VAT exemption for share transfers, which are otherwise outside VAT scope as shares are not goods or services under VAT framework. Stamp tax under Stamp Tax Law No. 488 applies to transaction documents at applicable rates, with exemptions available for specific structures including capital markets transactions. For framework on corporate taxation specifically for foreign companies, readers can consult our corporate tax guide for foreign companies. Practice may vary by authority and year.
Turkish lawyers who address asset transaction tax treatment work through the framework applying to asset purchases outside share transaction. Asset sale subjects the seller to gain recognition on transferred assets at the difference between sale price and tax basis — this can create substantial immediate tax liability compared to share transaction gain deferral or exemption possibilities. VAT applies to asset sales at 20% standard rate (or reduced rates for categories) unless exemptions apply, with the Article 17/4(c) framework providing specific exemption conditions for certain asset group transfers. Stamp tax implications vary with transaction structure — asset transfer agreements may trigger stamp tax at up to 0.948% of transaction value depending on structure. Real estate transfer as part of asset transaction triggers title deed fee (tapu harcı) at 4% of declared value, potential Value Added Tax on first-hand commercial real estate, and capital gains treatment for the seller. Tax-free merger conditions under Corporate Tax Law No. 5520 Article 19 provide tax-neutral treatment for qualifying mergers — requirements include merger between Turkish resident corporations, exchange of shares rather than cash consideration, continuation of business activity, and procedural compliance. Tax-free demerger under Article 19 requires transfer of active business line with associated assets and liabilities, proportional share distribution to divided company shareholders, and minimum holding and activity requirements. Failure to meet tax-free conditions triggers tax recognition on all transferred value with substantial cost consequences. Practice may vary by authority and year, and tax structuring benefits from integrated pre-transaction planning rather than reactive assessment after deal terms are fixed.
An English speaking lawyer in Turkey addressing cross-border M&A tax considerations works through the framework coordinating Turkish tax with foreign jurisdiction consequences. Double Taxation Treaty (DTT) analysis for Turkish transaction parties and foreign counterparty identifies applicable DTT coverage on capital gains (treaty-provisions vary, with many treaties allocating taxing rights to the source country for real estate-rich companies and to the residence country for operating company shares), dividends from Turkish subsidiary distributions (typically with reduced withholding rates under DTTs), interest on acquisition financing (with DTT interest article treatment), and royalties on intellectual property arrangements. Transfer pricing compliance under Corporate Tax Law No. 5520 Article 13 requires arm's length pricing for related-party transactions with documentation requirements — master file requirement for Turkish taxpayer groups with consolidated turnover exceeding TRY 500 million, country-by-country reporting for multinational groups with global consolidated turnover exceeding EUR 750 million. Foreign tax credits in the home jurisdiction for Turkish taxes paid require documentation and may be subject to limitations under home country rules. Exit tax considerations where the transferred undertaking has significant foreign operations may arise under specific home country rules. Dividend withholding on post-acquisition distributions to foreign parents currently operates at 15% under Presidential Decree No. 7887 of 22 December 2023 (increased from 10%), reducible through applicable DTT provisions. Practice may vary by authority and year, and cross-border tax structuring benefits from coordinated Turkish and foreign counsel engagement from transaction inception.
Employment law and HR integration in M&A
A Turkish Law Firm coordinating employment aspects of M&A transactions works through the framework that governs workforce continuity, employee rights, and integration considerations. Labor Law No. 4857 Article 6 establishes automatic employment continuity in asset transfers and certain mergers — when a workplace or business unit transfers as a going concern, employment contracts transfer automatically to the acquirer by operation of law with preservation of employee rights including seniority, accrued benefits, collective agreement coverage where applicable, and other acquired rights. Article 6 protection prevents transactions from being structured to circumvent employee rights through asset transfer rather than direct employment termination. The transferor and transferee share joint liability for employee obligations arising before the transfer for a two-year period following transfer. Share transactions do not directly trigger Article 6 because the employing entity remains the same (the target company) with only ownership changing — though change-of-control provisions in employment contracts (particularly senior management) may trigger consequences. Merger transactions under TTK operate through universal succession where employment contracts transfer to the surviving entity by operation of law as part of the overall succession. Practice may vary by authority and year, and employment integration planning benefits from assessment of transaction structure and employee categories.
Turkish lawyers who address senior management and retention arrangements work through the framework governing key employee continuity through transactions. Change-of-control provisions in senior management service contracts, stock option plans, and compensation arrangements may trigger accelerated vesting, severance payments, or termination rights upon completion of qualifying transactions. Retention agreements with key employees provide incentives for continued service through and beyond transaction completion — typical structures include retention bonuses contingent on continued employment, equity-based arrangements with vesting tied to post-closing milestones, and role guarantees addressing title, responsibilities, reporting lines, and compensation. Non-compete provisions for senior employees under TBK Article 444 permit post-employment competition restrictions with specific limitations including reasonable scope (geographical, temporal, activity), legitimate business interest justification, and compensation or consideration in some circumstances. Confidentiality obligations under TBK and employment contract provisions protect proprietary information during and after transactions. Labor court compulsory mediation under Law No. 7036 (effective 1 January 2018) requires pre-litigation mediation for individual labor disputes — transactions may trigger labor claims requiring mediation before court proceedings. Practice may vary by authority and year, and senior employee arrangements require individual contract review and specific planning for each key relationship.
An Istanbul Law Firm addressing workforce integration and post-closing employment matters works through the framework supporting operational integration while managing employment risks. Collective dismissal (toplu işçi çıkarma) under Labor Law Article 29 applies where post-closing restructuring involves termination of minimum numbers of employees within defined periods — compliance requires prior notification to İŞKUR (Turkish Employment Agency), consultation with worker representatives, and specific timing and procedural requirements. Severance calculation under Mülga 1475 Article 14 (continuing in force for severance) applies at one month's salary per year of service for qualifying terminations — acquirer assessment of accumulated severance liability is standard due diligence, and purchase price adjustments or escrow arrangements often address identified severance exposures. Collective bargaining agreement (toplu iş sözleşmesi) continuation following mergers or asset transfers operates through specific rules under Law No. 6356 — agreements typically continue binding the acquirer for the remaining term with procedural requirements. Workforce harmonization between acquirer and target workforce may require policy alignment, compensation structure integration, and specific transition arrangements — changes to existing employee terms generally require employee consent or follow procedures for unilateral change under limited circumstances. Union relations management where unionized workforce exists requires engagement with union representatives on transaction implications and integration plans. Practice may vary by authority and year, and post-closing employment integration benefits from structured planning addressing both individual employee and collective dimensions.
An Istanbul Law Firm coordinating sector-regulatory clearance that may apply beyond general merger control works through industry-approval requirements. Banking sector transactions require BDDK (Banking Regulation and Supervision Agency) approval under Banking Law No. 5411 where the transaction results in acquisition of qualifying ownership percentages (typically 10% initial threshold with additional thresholds at higher levels) or change of control of Turkish banks. BDDK review includes fit-and-proper assessment of new shareholders, capital adequacy verification, governance arrangement review, and other prudential considerations. Timing for BDDK review varies with complexity but typically requires several months for substantial transactions. Insurance sector transactions require approval from Sigortacılık ve Özel Emeklilik Düzenleme ve Denetleme Kurumu (SEDDK, the Insurance and Private Pensions Regulation and Supervision Agency) under Insurance Law No. 5684 with similar fit-and-proper framework. Capital markets transactions involving publicly traded companies trigger SPK (Capital Markets Board) oversight under Capital Markets Law No. 6362 including mandatory tender offer requirements where acquirer reaches ownership thresholds (generally 50%), public disclosure obligations for material transactions, and prospectus requirements for securities offerings in transaction context. Practice may vary by authority and year, and sector-regulatory coordination requires specialist expertise beyond general M&A practice.
Turkish lawyers who address energy sector regulatory framework work through the sector-specific law structure governing oil, natural gas, electricity, and renewable energy transactions. Electricity Market Law No. 6446 governs electricity generation, transmission, distribution, and supply with EPDK oversight — transactions affecting electricity licenses require EPDK approval including license transfer approvals, change-of-control approvals where license conditions include ownership requirements, and generation capacity or market share considerations. Natural Gas Market Law No. 4646 governs natural gas import, wholesale, and distribution with similar EPDK oversight. Petroleum Market Law No. 5015 governs petroleum refining, distribution, and retail with EPDK oversight for licensing and ownership changes. Renewable energy transactions additionally address incentive mechanism continuity (YEKDEM — Yenilenebilir Enerji Kaynakları Destekleme Mekanizması). Electronic communications transactions require BTK (Information and Communication Technologies Authority) approval under Electronic Communications Law No. 5809 with change-of-control framework for authorization holders. Media sector transactions (broadcasting) require RTÜK (Radio and Television Supreme Council) approval under Radio and Television Law No. 6112 with ownership concentration restrictions. Pharmaceutical sector transactions may trigger TİTCK (Turkish Medicines and Medical Devices Agency) review for manufacturing or distribution authorizations. Strategic sector transactions in defense, telecommunications infrastructure, and critical energy infrastructure may trigger additional review. Real estate-intensive transactions may trigger review under foreign real estate acquisition framework under Tapu Kanunu No. 2644 Article 35 for foreign company direct ownership. For framework on foreign investor company law, readers can consult our foreign investor company law guide. Practice may vary by authority and year.
Dispute resolution and M&A litigation framework
A Turkish Law Firm coordinating dispute resolution for M&A matters works through the framework covering both pre-closing disputes (letter of intent enforcement, exclusivity breach, confidentiality breach, negotiation disputes) and post-closing disputes (representations and warranties claims, indemnity claims, purchase price adjustment disputes, earnout disputes, non-compete enforcement). Dispute resolution forum selection in the SPA determines whether disputes proceed through Turkish courts (typically specialized commercial courts with jurisdiction over M&A disputes under HMK No. 6100 framework), Turkish arbitration (domestic arbitration under TBK arbitration provisions or HMK), or international arbitration (under International Arbitration Law No. 4686 framework with institutional rules of ISTAC, ICC, LCIA, SIAC, or other institutions). Selection criteria include enforceability considerations (Turkish court judgments enforceable domestically but foreign enforcement; arbitration awards enforceable under 1958 New York Convention as ratified by Türkiye through Law No. 3731 on 25 September 1991 in over 170 countries), procedural preferences (confidentiality, speed, expertise of adjudicators), cost considerations, and other factors. Practice may vary by authority and year.
Turkish lawyers who address representations and warranties claim management work through the framework handling post-closing claims for R&W breaches. Notice requirements under the SPA typically specify time limits, content requirements, and procedural steps for claim notification — failure to comply with notice requirements can defeat otherwise valid claims. Investigation and quantification of claimed losses requires factual development supporting breach establishment and damage calculation — typical elements include contemporaneous documentation, witness statements, expert analysis for technical or valuation matters, and other evidence. Mitigation obligations under TBK Article 52 require the claimant to take reasonable steps to minimize losses — failure to mitigate may reduce recoverable damages. Set-off rights against other amounts owed (for example earnout payments pending in the other direction) provide strategic leverage in dispute management. Escrow claims against indemnity escrow follow the SPA's specific escrow claim procedures with notice, documentation, and release timing framework. Settlement negotiation through direct party discussions or formal mediation can resolve claims without litigation — Turkish legal framework accommodates various settlement structures with specific enforcement considerations. Representation and warranty insurance (where obtained for the transaction) provides insurance-based recovery outside direct seller claim framework, reducing friction between buyer and seller on specific claim categories.

An Istanbul Law Firm addressing international arbitration for cross-border M&A disputes works through the framework under International Arbitration Law No. 4686 and institutional rules. International Arbitration Law No. 4686 framework applies to arbitrations seated in Türkiye with international dimension — the law adopts UNCITRAL Model Law framework with Turkish adaptations. ISTAC (Istanbul Arbitration Centre) established under Law No. 6570 of 29 November 2014 and operational from 26 October 2015 provides Turkish institutional arbitration with bilingual capability and Istanbul seat — ISTAC Rules govern procedural framework with 2015 rules and subsequent updates. ICC (International Chamber of Commerce) arbitration under ICC Rules provides established international framework with Paris headquarters and regional case management — ICC arbitration seated in Istanbul or elsewhere operates under ICC Rules with applicable law. LCIA (London Court of International Arbitration) Rules and SIAC (Singapore International Arbitration Centre) Rules provide alternative institutional frameworks with procedural characteristics. Emergency arbitrator provisions under institutional rules permit interim relief before full tribunal constitution. Enforcement of foreign arbitral awards in Türkiye under 1958 New York Convention (ratified through Law No. 3731 of 1991) proceeds through specific recognition proceedings with Article V refusal grounds review.

Post-closing integration and regulatory follow-up
A lawyer in Turkey coordinating post-closing integration for M&A transactions works through the framework converting signed agreements into operational reality with coordinated legal, regulatory, and operational execution. Trade Registry updates under TTK Article 40 following share acquisitions, merger or demerger registrations, conversion completions, and other corporate events require specific filings with timing obligations — delayed filings can create regulatory consequences and potential liability. Corporate governance transitions including director resignations and appointments, officer changes, signature circular updates (imza sirküleri), and other governance changes require coordinated execution with Trade Registry notification. Share ledger (pay defteri) updates for A.Ş. or quota ledger updates for Ltd. Şti. document the new shareholding structure. Tax registration updates with applicable tax office address any changes to taxpayer information including responsible person updates, address changes, and other modifications. Bank account documentation updates reflecting new authorized signatories, beneficial ownership changes, and other banking relationship modifications support operational continuity. Practice may vary by authority and year, and post-closing administrative execution requires coordinated project management across multiple workstreams.
Turkish lawyers who address commercial agreement integration work through the framework identifying change-of-control consent requirements, novation needs, and other commercial agreement impacts of the transaction. Change-of-control provisions in material contracts (customer agreements, supplier agreements, distribution arrangements, technology licenses, financing agreements, real estate leases) determine whether transaction completion triggers rights including termination rights, consent requirements, payment acceleration, or other consequences. Early engagement with specific counterparties on change-of-control consents supports smooth transition and avoids post-closing disputes. Loan and credit facility consent requirements for acquisition financing or target company financing typically require lender approval — unauthorized change of control can trigger event of default with acceleration consequences. Real estate lease assignment or consent requirements under Turkish lease framework address premises continuity. Licensing and franchise agreement continuity addresses specific third-party relationships that require maintenance. Post-closing audit rights under specific agreements may trigger examination activities addressing the transaction's effects. Practice may vary by authority and year.
An English speaking lawyer in Turkey addressing ongoing compliance and regulatory follow-up works through the framework monitoring regulatory obligations arising from the transaction itself. Merger control commitment monitoring where the Competition Authority authorized the transaction with commitments (behavioral or structural remedies) requires ongoing compliance tracking and periodic reporting as required by the decision. Sector-regulatory reporting following transactions in regulated industries may include post-closing notifications, new shareholder disclosures, activity reports, and other ongoing requirements. MASAK (Financial Crimes Investigation Board) compliance under Law No. 5549 covers beneficial ownership reporting requirements and ongoing transaction monitoring obligations for financial institutions involved in the transaction and the target company where applicable. KVKK (Personal Data Protection Authority) notifications for data controller changes or significant data processing modifications following the transaction may be required under Law No. 6698. Annual corporate governance disclosures including shareholders' list updates, board composition documentation, and other recurring requirements continue for the post-transaction entity. Tax filing obligations including potential transition-year complexities address the impact of mid-year ownership or corporate structure changes. Practice may vary by authority and year, and ongoing compliance discipline supports sustainable value realization from the transaction.

Frequently asked questions
- What are the current merger control notification thresholds in Turkey? Under Communiqué No. 2022/2 as amended, thresholds are: (a) combined Turkish turnover exceeding TRY 750 million with at least one party at TRY 250 million Turkish turnover, or (b) transferred Turkish turnover exceeding TRY 250 million with acquirer worldwide turnover exceeding TRY 3 billion. Communiqué No. 2026/2 of 11 February 2026 raised these thresholds; current figures should be verified against the latest Communiqué text.
- Are technology undertakings subject to different merger control thresholds? Yes. Communiqué No. 2024/2 introduced and Communiqué No. 2026/2 continued special provisions for technology undertakings including digital platforms, software, fintech, biotech, pharmaceuticals, agrochemicals, and health technology. Transactions involving these undertakings face lower notification thresholds reflecting Turkish Competition Authority policy to closely monitor concentration in technology markets.
- What is the merger control review timeline? Competition Law No. 4054 Article 10 provides 15 days preliminary review from complete notification submission. If no decision is issued within 30 days, the transaction is deemed approved. Final review when initiated extends the timeline with specific case-by-case duration depending on complexity and remedial considerations.
- What corporate approvals are required for M&A in Turkey? Share acquisitions generally require target board/shareholder approval depending on constitutional documents and shareholder agreement provisions. Mergers under TTK Articles 140-148 require board approval, general assembly approval with qualified majority, and specific shareholder protections. Asset transactions require target board approval with potential shareholder approval depending on materiality.
- How does universal succession work in Turkish mergers? Under TTK Articles 136-158, merger transactions transfer all assets, liabilities, rights, and contractual obligations of the merging company to the surviving entity by operation of law upon Trade Registry registration. Individual asset transfers, contract novations, or employee consents are not required for the core transfer, though consents may apply for change-of-control provisions in contracts.
- Can share transfers be tax-free? Individual sellers benefit from Income Tax Law No. 193 Article 80 exemption for shares held more than two years in most cases. Corporate sellers may qualify for 75% participation exemption under Corporate Tax Law No. 5520 Article 5/1-e for shares in qualifying Turkish subsidiaries held more than two years. Tax-free merger under Article 19 requires conditions including share-based consideration and activity continuation.
- What are the VAT implications of M&A transactions? Share transfers are outside VAT scope and benefit from Article 17/4(c) exemption. Asset sales generally trigger VAT at 20% standard rate unless exemptions apply. Tax-free merger and demerger transactions under Article 19 conditions receive VAT-neutral treatment.
- What happens to employees in an M&A transaction? Share transactions preserve the employing entity with no automatic employment change. Asset transactions and mergers trigger Labor Law Article 6 automatic employment continuity with transferor-transferee joint liability for pre-transfer obligations during a two-year period. Senior management change-of-control provisions in service contracts may trigger rights including accelerated vesting or severance.
- Which regulatory authorities approve sector-transactions? Banking — BDDK under Banking Law No. 5411. Insurance — SEDDK under Insurance Law No. 5684. Capital Markets — SPK under Law No. 6362. Energy — EPDK under Electricity Market Law No. 6446, Natural Gas Market Law No. 4646, Petroleum Market Law No. 5015. Electronic Communications — BTK under Law No. 5809. Media — RTÜK under Law No. 6112. Pharmaceuticals — TİTCK. Transactions in regulated sectors require both general merger control and sector-clearance.
- How are M&A disputes resolved? SPA dispute resolution clauses typically select Turkish commercial courts or international arbitration (ISTAC, ICC, LCIA, SIAC). Arbitration awards benefit from 1958 New York Convention enforcement in over 170 countries. Commercial court judgments enforceable domestically; foreign enforcement requires tenfiz under MÖHUK No. 5718 Article 50.
- What are representations and warranties in an SPA? Factual statements by the seller about the target's condition. Fundamental representations (capacity, authority, title) typically carry uncapped indemnity. General representations (financial statements, contracts, litigation, compliance) carry time limits (12-24 months typical) and materiality qualifiers with caps. Tax representations survive for the applicable statute of limitations. Breaches trigger indemnity claims subject to notice, quantification, and other procedural requirements.
- What is an earnout? A portion of purchase price conditioned on post-closing performance against defined metrics (EBITDA, revenue, milestones) over a measurement period. Earnouts bridge valuation gaps between buyer and seller but create post-closing operational and dispute management challenges. SPA drafting must address measurement definitions, seller protections against buyer manipulation, and dispute resolution for earnout calculations.
- Can foreign law govern an M&A transaction in Turkey? Yes, parties may select foreign governing law for transaction documents. Turkish law governs share transfer mechanics for Turkish companies, Turkish mandatory provisions (including competition law, labor law, and specific corporate provisions), and Turkish-situated real estate. SPA commercial provisions may validly adopt foreign governing law, though enforceability for Turkish counterparties requires specific consideration.
- What is the timeline for an M&A transaction in Turkey? Typical transactions complete in 3-9 months from initial letter of intent through closing, with duration depending on due diligence scope, regulatory approvals, financing arrangements, and transaction complexity. Banking, energy, and other regulated sector transactions with sector-approvals often extend to 6-12 months. Competition Authority clearance alone can add 1-2 months where required.
- How does ER&GUN&ER Law Firm structure M&A engagements? Engagements begin with strategic planning and transaction structure selection, proceed through due diligence coordination, transaction documentation drafting and negotiation, regulatory approval coordination across Competition Authority and sector-specific authorities where applicable, closing execution, and post-closing integration. Engagements integrate Turkish legal expertise with international transaction practice for cross-border deals.
