Bulgaria 2026: M&A and Merger Control After the Competition Law Amendments, What Buyers & Sellers Must Do

Who this is for: in-house counsel, corporate buyers and sellers, private equity investors and deal advisers. Purpose: to explain the practical changes to merger notification, clearance planning, competition compliance and contract drafting that follow Bulgaria’s 2026 amendments to the Competition Protection Act, and to give deal teams a usable playbook.

Merger control Bulgaria has entered a new phase in 2026, and any deal team touching a Bulgarian target needs to understand what has changed before signing. The amendments to the Competition Protection Act (CPA) recalibrate the scope of reviewable transactions, address the treatment of excessively high prices, and sharpen the enforcement posture of the Commission for Protection of Competition. For buyers, sellers and private equity sponsors, the practical consequences run through due diligence, notification strategy, timeline planning and, critically, the wording of the sale and purchase agreement. This guide translates the 2026 changes into concrete steps deal teams can act on immediately.

Quick summary, what changed and why it matters for merger control Bulgaria

The 2026 CPA amendments matter because they touch two distinct workstreams that deal teams often treat separately: transactional merger clearance and ongoing conduct compliance. The reforms bring them closer together, meaning a competition issue discovered in diligence can now affect both whether a deal clears and how the target is priced and warranted.

• Broadened focus on merger scope. The amended framework clarifies which acquisitions, joint ventures and asset transfers fall within the notification regime, reducing the room for parties to assume a transaction sits outside review.
• Attention to excessively high pricing. The amendments reinforce the treatment of excessively high prices, creating a conduct risk that can survive completion and attach to the acquired business.
• A firmer enforcement posture. The Commission for Protection of Competition (CPC) is expected to apply its powers more actively, with structural and behavioural remedies, interim measures and financial penalties all in play.
• Tighter interaction with EU rules. For transactions crossing EU thresholds, coordination with the European Commission and the EU Merger Regulation remains essential, and the amendments do not displace that layer.

Snapshot, immediate steps for ongoing deals

• Re-run the notification analysis for any live transaction to confirm whether Bulgarian filing is now triggered.
• Add a targeted competition module to diligence covering pricing practices and any conduct that could attract the excessive-pricing rule.
• Review draft transaction documents for notification covenants, standstill mechanics and antitrust risk allocation.
• Build realistic clearance time into the deal timetable, including a buffer for information requests.
• Engage Bulgarian competition counsel early, ideally before signing, to shape filing strategy. See our merger control in Bulgaria, overview for context.

The amended Competition Protection Act, competition law Bulgaria framework and key provisions

The legal foundation for merger control Bulgaria is the Competition Protection Act, administered and enforced by the Commission for Protection of Competition. The 2026 amendments were adopted through the ordinary legislative process of the National Assembly and published in the State Gazette (Darzhaven Vestnik), which is the authoritative source for the operative text and its date of entry into force. Deal teams should always work from the published State Gazette version rather than press summaries, because the precise wording of definitions and thresholds determines whether a filing obligation arises.

At a structural level, the CPA continues to serve two functions. First, it operates the ex ante concentration control regime under which qualifying mergers, acquisitions and certain joint ventures must be notified to the CPC and cleared before implementation. Second, it prohibits anti-competitive conduct, abuse of dominance, restrictive agreements and, now with renewed emphasis, excessively high pricing. The 2026 reforms adjust both pillars, which is why competition law Bulgaria can no longer be treated as a purely regulatory afterthought in an M&A process.

The amendments also preserve the dividing line with EU competition law. Where a concentration has an EU dimension because it meets the turnover thresholds in the EU Merger Regulation, the European Commission generally has exclusive jurisdiction, subject to referral mechanisms. Below those thresholds, national review under the CPA applies. Understanding where a transaction sits in that architecture is the first task for any cross-border deal.

What the excessively high price prohibition covers

A significant feature of the 2026 package for transactional lawyers is the reinforced treatment of excessively high prices. Conceptually, this is a form of exploitative abuse: it targets situations where an undertaking with market power sets prices that bear no reasonable relation to the economic value of the goods or services supplied. The analysis typically compares price to cost, or benchmarks the price against comparable markets or competitors.

For deal teams the significance is that this is a conduct risk, not merely a filing question. If a target has been charging excessively high prices, the exposure, potential fines, corrective measures and reputational damage, can persist after completion and be inherited by the buyer. Examples of conduct that may attract scrutiny include a dominant supplier imposing unjustified price increases, pricing structures with no cost justification, or discriminatory pricing that exploits captive customers. The relevant EU case law on exploitative pricing, accessible through the Court of Justice of the European Union, remains an important interpretive reference for how such conduct is assessed.

Changes to merger control scope and definitions

The amendments sharpen the definitions that determine whether a transaction is a notifiable concentration. In broad terms, a concentration arises where there is a lasting change of control, whether through a merger of previously independent undertakings, the acquisition of direct or indirect control over another undertaking, or the creation of a full-function joint venture. Control can be acquired through share purchases, asset acquisitions, contractual arrangements or a combination of these.

Practically, deal teams should not assume that an asset deal or a minority acquisition falls outside the regime. What matters is whether the transaction confers decisive influence, the ability to determine strategic commercial decisions. Minority stakes coupled with veto rights over budgets, business plans or senior appointments can amount to de facto control. The 2026 clarifications make it harder to rely on formal labels; the substance of the control relationship governs.

Bulgaria merger notification triggers and who must notify, practical tests for deal teams

Determining whether a Bulgaria merger notification is required is the single most important gate in deal planning, because implementing a notifiable concentration without clearance exposes the parties to serious consequences. Deal teams should work through a structured practical test rather than relying on intuition.

• Identify the transaction type. Is it a merger, an acquisition of control, or the creation of a full-function joint venture? If none of these, concentration control may not apply.
• Map the control change. Determine whether the transaction confers sole or joint control, and whether it is lasting. Examine board composition, veto rights and shareholder agreements to test for de facto control.
• Run the turnover tests. The CPA notification regime is triggered by aggregate and individual turnover thresholds attributable to the parties in Bulgaria. Because the exact figures are set by statute and can be adjusted, always verify the current thresholds against the CPC’s published guidance and the State Gazette text before concluding no filing is needed.
• Assess overlaps and affected markets. Even where turnover thresholds are met, the substantive concern depends on horizontal overlaps, vertical relationships and combined market shares.
• Check special cases. Minority acquisitions with governance rights, staged transactions and interconnected agreements can aggregate for the purposes of the analysis.

Where the outcome is uncertain, pre-notification contact with the CPC and a documented assessment by Bulgarian competition counsel are the prudent course. A defensible file showing why the parties concluded a filing was or was not required is valuable if the transaction is later scrutinised.

Cross-border transactions and multiple filings, coordinating EU/other jurisdictions

Cross-border M&A Bulgaria transactions frequently trigger filings in more than one jurisdiction. The threshold question is whether the deal has an EU dimension. If the parties’ worldwide and EU-wide turnover meets the EU Merger Regulation thresholds, the European Commission has jurisdiction and a Bulgarian filing is generally displaced, subject to the referral system that can send cases back to national authorities or up to the Commission. The European Commission’s DG Competition materials set out how those mechanisms operate.

Below the EU thresholds, parallel national filings may be required in several member states, including Bulgaria. Coordination then becomes a project-management exercise: aligning filing dates, ensuring consistent factual narratives across jurisdictions, managing the longest-pole timeline, and synchronising any remedies discussions. Inconsistencies between filings can undermine credibility with reviewing authorities, so a single coordinating counsel or a tightly managed working group is advisable.

When to file, pre-signing, conditionality and standstills

In most cases the notification is prepared after signing but before completion, with clearance built in as a condition precedent to closing. The standstill principle means the parties must not implement the concentration, must not integrate operations, exchange competitively sensitive information beyond what is necessary, or exercise control, until clearance is obtained. Structuring the deal with a clear conditionality package, a defined long-stop date and appropriate hell-or-high-water or best-efforts obligations is essential to manage the gap between signing and closing.

Filing process, timelines and review phases, a practical timeline

The CPC review generally follows a two-phase structure familiar from EU practice. A short pre-notification stage allows the parties to engage informally, test the completeness of the draft filing and identify likely issues. A well-prepared pre-notification phase materially reduces the risk of the clock being stopped later for missing information.

Once a complete notification is submitted, the CPC conducts an initial review to determine whether the concentration raises serious competition concerns. Transactions with no meaningful overlaps are typically cleared at this first stage. Where the CPC identifies concerns that require deeper investigation, the matter proceeds to an in-depth review, which is longer and often involves market testing, third-party contact and remedies negotiation. Because statutory periods can be suspended by information requests, deal teams should treat published timeframes as minimums and build a realistic buffer into the transaction timetable. Verify the current statutory periods against the CPC’s procedural guidance before committing to a completion date.

Typical documents and financial schedules required

• Corporate structure charts for the acquirer and target groups, showing ultimate ownership and control.
• Turnover data for the relevant financial years, allocated to Bulgaria and, where relevant, the EU and worldwide.
• Descriptions of the affected markets, including product and geographic market definitions, market shares and competitor identities.
• Transaction documents evidencing the change of control, including share purchase or asset purchase agreements and shareholder arrangements.
• Internal documents analysing the rationale for the transaction and the competitive landscape, where requested.

Requests for information (RFI) and how to respond quickly

Information requests are the most common cause of timeline slippage. The CPC may issue an RFI where the notification is incomplete or where further data is needed to assess an overlap. Responding quickly and completely keeps the review on track; incomplete responses risk the clock being stopped. Practical steps include assembling a data room of likely-required materials during pre-notification, nominating a single point of contact for CPC correspondence, and ensuring economists and commercial teams are on standby to produce market data at short notice. Speed and accuracy in RFI responses are among the highest-leverage things a deal team can control.

Clearance risk and enforcement, remedies, fines and behavioural tools in merger control Bulgaria

Where the CPC concludes that a concentration would significantly impede effective competition, it can prohibit the transaction or clear it subject to remedies. Remedies fall into two broad categories. Structural remedies require a lasting change to the market structure, typically the divestment of a business, brand or asset to a suitable purchaser. Behavioural remedies impose ongoing obligations on the merged entity’s conduct, for example, access commitments, supply undertakings or firewalls to protect competitively sensitive information. Structural remedies are generally preferred where a durable competition concern exists, because they do not require continuous monitoring.

Beyond merger control, the reinforced treatment of excessively high prices adds a conduct-enforcement dimension that can bite on M&A parties. If the target’s pricing practices are found to be exploitative, the CPC can impose corrective measures and financial penalties, and can adopt interim measures in appropriate cases. For a buyer, that means a competition problem identified in diligence is not only a clearance risk but a valuation and warranty issue.

Pre-2026 vs Post-2026: Practical differences for deal teams

How buyers can mitigate post-closing risk (holdbacks, escrow, conditional completion)

Buyers should treat competition exposure as a discrete risk category in the deal structure. Where diligence identifies pricing conduct that could attract the excessive-pricing rule, a portion of consideration can be held back or placed in escrow to fund potential penalties or remediation. Where the exposure is material and quantifiable, conditional completion, with the resolution of a specific competition issue as a condition precedent, may be appropriate. Buyers can also negotiate specific indemnities that survive the general warranty period and are ring-fenced from ordinary liability caps.

How sellers can limit exposure (reps, indemnities, disclosure)

Sellers, conversely, will seek to contain competition exposure through careful disclosure and tightly drafted warranties. Full and fair disclosure of pricing practices and any regulatory contact reduces the risk of a warranty claim, because a buyer generally cannot claim for matters fairly disclosed. Sellers will also press for caps, baskets and time limits on any competition indemnity, and will resist open-ended obligations. A disclosure exercise that documents the commercial rationale for the target’s pricing can be a valuable defensive record.

Drafting deal documentation after the 2026 amendments, contract clauses and negotiation strategy

The 2026 changes should feed directly into the transaction documents. Three areas deserve particular attention: the mechanics for obtaining clearance, the allocation of clearance risk, and the allocation of inherited conduct risk from the excessive-pricing rule. Each should be addressed explicitly rather than left to boilerplate.

On clearance mechanics, the SPA should contain a clear condition precedent requiring Bulgarian merger clearance (and any other required competition approvals), together with covenants governing which party leads the filing, the standard of effort each must apply, and how the parties cooperate on information and remedies. On risk allocation, the parties should agree who bears the risk if clearance is refused or conditioned, including whether the buyer must accept remedies, and whether a break fee or termination right applies at the long-stop date. On conduct risk, the documents should address whether and how the buyer is protected against liability arising from the target’s pre-completion pricing.

Negotiation strategy will turn on leverage and risk appetite. A buyer with strong bargaining power may seek a hell-or-high-water obligation requiring the seller to do whatever is necessary to secure clearance. A seller with a competitive process may resist and push clearance risk onto the buyer. The excessive-pricing dimension adds a further axis: buyers will want a specific indemnity, sellers will want it capped and time-limited.

Model clause, merger notification covenant (recommended wording + explanation)

A workable notification covenant should require the responsible party to prepare and submit a complete notification to the Commission for Protection of Competition promptly after signing, to respond to information requests without undue delay, to keep the other party informed and consult on material communications, and to use a defined standard of efforts to obtain clearance before the long-stop date. It should also address whether the buyer is obliged to accept remedies and, if so, up to what limit. The purpose of the clause is to convert an abstract clearance condition into an allocation of specific obligations, so that neither party can frustrate the process and each knows its exposure.

Model clause, excessive-pricing indemnity / cap / escrow construct

Where diligence identifies pricing risk, a dedicated indemnity is preferable to reliance on general warranties. A robust construct will define the covered conduct (pre-completion pricing that breaches the CPA), specify the losses covered (fines, corrective costs, third-party claims), set a monetary cap and time limit calibrated to the assessed risk, and, where the risk is significant, back the indemnity with an escrow or holdback so that funds are available if a claim materialises. Ring-fencing this indemnity from the general liability cap ensures the buyer is not left under-protected against a specific, foreseeable competition exposure.

Due diligence checklist for competition issues

Competition due diligence should be tailored to the 2026 changes, with particular attention to pricing conduct that could engage the excessive-pricing prohibition. A focused checklist keeps the exercise proportionate while covering the risks that now matter most for antitrust compliance Bulgaria.

• Pricing practices. Review price lists, price-setting methodology, margins and any recent price increases for evidence of exploitative pricing, especially where the target holds market power.
• Market position. Assess market shares and dominance in each affected market, since exploitative-pricing risk rises with market power.
• Customer and supplier contracts. Examine long-term agreements, exclusivity, and any terms that could amount to vertical restraints.
• Internal documents. Look for pricing memos, board papers and competitor communications that reveal how prices are set and whether competition risk was considered.
• Regulatory history. Identify any prior CPC contact, complaints or investigations touching the target.
• Overlap mapping. Confirm horizontal and vertical overlaps with the buyer’s own activities to gauge clearance risk.

When to engage Bulgarian competition counsel and economists

Bulgarian competition counsel should be engaged as soon as a potential overlap or pricing risk is identified, ideally before signing, so that filing strategy, standstill mechanics and risk allocation can be built into the documents rather than retrofitted. Economists add value where market definition, market share or the assessment of price against economic value is contested, which is precisely the terrain of the excessive-pricing rule. Early involvement is almost always cheaper than late remediation.

Practical examples and worked scenarios

The following short scenarios illustrate how the 2026 framework shapes deal approach in common transaction types.

• Domestic acquisition with an overlap. A Bulgarian buyer acquires a competitor. Turnover thresholds are met and the parties overlap in one product market. Approach: confirm the Bulgaria merger notification obligation, prepare a filing with market-share analysis, and structure completion as conditional on CPC clearance, with a clear notification covenant and long-stop date.
• Cross-border buy of a Bulgarian target. A foreign strategic acquirer buys a Bulgarian company. First test the EU dimension; if EU thresholds are met, coordinate with the European Commission, otherwise file with the CPC and manage any parallel national filings. Approach: run a jurisdictional analysis early and appoint coordinating counsel to keep filings consistent.
• Asset purchase with pricing exposure. A buyer acquires the assets of a dominant supplier whose recent price increases raise excessive-pricing questions. Approach: conduct focused pricing diligence, negotiate a ring-fenced indemnity backed by escrow, and consider a specific condition precedent if the exposure is material.
