A Practical Legal Guide to Share Dilution, Pre-Emptive Rights and Minority Shareholder Protection Under Turkish Law
Last Updated: August 2026

A foreign investor may acquire 10%, 20%, 30% or even 49% of a Turkish company and reasonably expect that percentage to represent its continuing economic and voting position.

However, one of the most significant risks faced by minority investors is a subsequent capital increase.

Consider the following example:

A foreign investor owns 30% of a Turkish company.

The founders control the remaining 70%.

The company then adopts a substantial capital increase. If the foreign investor does not participate in the new capital or is prevented from participating, its ownership may fall from:

30% to 10%, 5% or even lower.

This is generally called share dilution.

But is this legal?

The answer is:

A capital increase that causes dilution is not automatically unlawful under Turkish law. However, a capital increase designed or implemented to unfairly dilute a minority shareholder may be challenged.

Turkish Commercial Code No. 6102 (“TCC”) gives shareholders important protections through:

• pre-emptive subscription rights,
• the equal treatment principle,
• restrictions on cancelling pre-emptive rights,
• actions for annulment of general assembly resolutions,
• actions concerning invalid corporate resolutions, and
• interim judicial protection.

For foreign investors, speed is particularly important because some challenges are subject to very short statutory deadlines.

1. What Is Share Dilution?

Share dilution occurs when a company issues new shares and an existing shareholder’s percentage decreases because that shareholder does not acquire a proportional amount of the newly issued shares.

For example:

Before the capital increase:

Founder: 70%
Foreign Investor: 30%

Suppose the company’s capital is TRY 1,000,000.

The company increases its capital to TRY 4,000,000.

If the founder subscribes to the new shares but the foreign investor does not, the foreign investor may continue to hold the same nominal amount of shares but represent a much smaller percentage of the total company.

The legal consequences can be significant.

Dilution may reduce the investor’s:

• voting power,
• dividend entitlement as a percentage of total distributions,
• influence over general assembly resolutions,
• ability to block qualified-majority decisions,
• entitlement upon liquidation,
• negotiating power, and
• minority rights linked to statutory ownership thresholds.

Therefore, dilution can dramatically alter the economic and corporate balance originally agreed between the investor and the founders.

2. Is Share Dilution Automatically Illegal?

No.

This is the first rule foreign investors must understand.

A company may genuinely require additional capital because it needs money for:

• expansion,
• new investments,
• debt repayment,
• working capital,
• financial restructuring,
• acquisitions, or
• compliance with financial requirements.

If the company legitimately increases its capital and provides all shareholders with an equal opportunity to participate proportionally, the fact that one shareholder chooses not to contribute additional funds does not normally make the transaction unlawful.

Turkish court practice recognises this distinction.

Where a company has a genuine financial need and the minority shareholder has been offered a lawful opportunity to exercise its subscription rights, dilution resulting from the shareholder’s failure to participate may be legally valid.

Therefore, the real legal question is generally not:

“Did the investor’s percentage decrease?”

but rather:

“Was the capital increase carried out lawfully and for a legitimate corporate purpose, or was it designed to unfairly weaken the minority shareholder?”

3. The Foreign Investor’s Most Important Protection: Pre-Emptive Rights

In a Turkish joint stock company — Anonim Şirket (A.Ş.) — Article 461 of the Turkish Commercial Code provides the fundamental protection.

Each shareholder generally has the right to acquire newly issued shares in proportion to their existing shareholding.

This is known in Turkish law as:

Rüçhan Hakkı — Pre-Emptive Subscription Right

Suppose a foreign investor owns 25% of an A.Ş.

If the company issues 1,000 new shares, the investor should generally have the opportunity to subscribe for 250 of those shares.

If the investor exercises this right fully, its percentage can generally remain at 25%.

The purpose of the pre-emptive right is therefore not merely to allow the shareholder to invest more money.

It protects the shareholder against involuntary dilution.

4. How Much Time Must Be Given to Exercise Pre-Emptive Rights?

Under Article 461, the board of directors must determine the conditions for exercising the new share subscription right.

Shareholders must generally be given at least 15 days to exercise the right.

This period is important for foreign investors.

A Turkish company should not deliberately structure the procedure so that a foreign shareholder learns about the capital increase only after the opportunity to subscribe has effectively expired.

If the majority deliberately:

• sends notices to an outdated address,
• fails to make required announcements,
• conceals the capital increase,
• prevents access to relevant documents, or
• provides an unlawfully short subscription period,

these matters may strengthen a later challenge.

5. Can the Majority Simply Cancel the Foreign Investor’s Pre-Emptive Rights?

Not freely.

Under TCC Article 461, an A.Ş. may restrict or remove shareholders’ pre-emptive rights only where just cause exists.

In addition, the decision requires at least 60% of the share capital to vote in favour.

Most importantly, the law expressly prevents the mechanism from being used to unjustifiably benefit one person or unjustifiably disadvantage another.

This is one of the strongest statutory protections against abusive dilution.

6. What Can Constitute “Just Cause”?

The Commercial Code gives examples including:

• public offerings,
• acquisition of businesses,
• acquisition of parts of businesses,
• acquisition of participations, and
• employee participation in the company.

These examples are not necessarily exhaustive.

However, the important point is that the majority cannot simply say:

“We do not want the foreign investor to participate in this capital increase.”

That is not, by itself, a legitimate reason for cancelling a shareholder’s statutory rights.

A restriction must serve a genuine corporate purpose.

7. A Capital Increase Cannot Be Used to Transfer Value to the Majority

The protection goes beyond voting percentages.

Consider a company whose true economic value is EUR 20 million but whose registered capital is relatively low.

The majority shareholders approve a large capital increase and issue new shares at nominal value exclusively to themselves after excluding the foreign investor.

The result may be that the majority receives economically valuable new shares for a relatively small contribution while the foreign investor’s percentage and economic position are severely reduced.

In such a situation, the legal analysis may involve:

• abuse of majority power,
• violation of pre-emptive rights,
• unequal treatment,
• absence of just cause,
• unfair benefit to the majority, and
• violation of good faith.

The economic substance of the transaction may therefore be as important as its formal corporate documentation.

8. The Equal Treatment Principle Protects Foreign Investors

Article 357 of the Turkish Commercial Code provides that shareholders under equal circumstances must be treated equally.

This principle can become particularly important in a capital increase.

For example, problems may arise where:

• the majority receives advantageous subscription conditions,
• the foreign shareholder receives less time to subscribe,
• only the majority is given information concerning the transaction,
• new shares are effectively reserved for related parties, or
• the transaction is structured to benefit selected shareholders without objective justification.

Foreign nationality does not justify different treatment.

9. When Does a Capital Increase Become Suspicious?

No single factor automatically proves abuse.

However, several circumstances together may indicate that the real objective is minority dilution rather than legitimate financing.

Typical warning signs include:

• an unusually large increase compared with the company’s actual financing needs;
• no credible business reason for raising new capital;
• the company already having significant available financial resources;
• the majority shareholder being the only realistic party capable of funding the increase;
• pre-emptive rights being restricted without convincing justification;
• new shares being issued to the majority or its affiliates;
• the transaction taking place immediately after a shareholder dispute;
• the foreign investor previously holding an important minority threshold;
• the increase reducing the investor below that statutory threshold;
• incomplete or misleading information being given to the minority shareholder;
• unusually short or defective notice procedures; and
• the majority receiving a substantial economic advantage from the transaction.

Courts normally evaluate the transaction as a whole.

10. A Very Large Capital Increase Can Be Challenged

Suppose:

Founder: 80%
Foreign Investor: 20%

The company has no serious liquidity problem.

Immediately after a dispute with the foreign investor, the founder proposes increasing the company’s capital tenfold.

The investor cannot economically provide its proportionate contribution on short notice.

The founder subscribes for almost all the new shares.

The foreign investor’s percentage falls from 20% to 3%.

This structure should be examined very carefully.

Turkish judicial practice has recognised that excessively increasing capital in circumstances designed to prevent financially weaker minority shareholders from maintaining their ownership position can conflict with the principle of good faith.

But the existence of a large increase alone is not sufficient.

The company may still prove that the increase was genuinely necessary.

11. Genuine Financial Need Can Defeat a Dilution Challenge

Foreign investors should also understand the other side of the analysis.

Suppose the company:

• has lost substantial equity,
• needs urgent financing,
• cannot obtain reasonable external financing,
• has major debts,
• risks insolvency, and
• requires new capital to continue operations.

The majority proposes a capital increase.

All shareholders are properly informed and given proportional subscription rights.

The foreign investor decides not to invest additional money.

Its percentage falls.

In that situation, a court may conclude that the dilution was simply the economic consequence of a legitimate capital increase.

Turkish case law has upheld capital increases where the company’s financial circumstances demonstrated a genuine need for additional capital and the transaction was not shown to have been undertaken in bad faith.

Therefore, minority protection does not amount to a permanent guarantee that a shareholder can maintain the same percentage without contributing to future financing.

12. How Can the Foreign Investor Challenge the General Assembly Resolution?

If an A.Ş.’s capital increase was adopted by the general assembly, the principal remedy may be an action for annulment of the general assembly resolution.

Under TCC Article 445, general assembly resolutions contrary to:

• the law,
• the articles of association, or
• particularly the principle of good faith

may be challenged before the Commercial Court of First Instance at the company’s registered office.

The statutory deadline is extremely important:

The action must generally be filed within three months from the date of the general assembly resolution.

This is a short deadline.

Foreign shareholders should therefore avoid waiting for lengthy negotiations with the majority while the statutory period expires.

13. The Investor Should Record Opposition at the General Assembly

Where the investor attends the general assembly, litigation strategy begins during the meeting itself.

Under TCC Article 446, a shareholder who attends the meeting and later wishes to bring an annulment action will generally need to:

1. vote against the capital increase resolution; and
2. have its opposition recorded in the general assembly minutes.

There are separate statutory rules where, for example:

• the meeting was improperly called,
• the agenda was defective,
• unauthorised persons voted,
• the shareholder was unlawfully prevented from participating, or
• voting rights were unlawfully denied.

Accordingly, foreign investors should ideally attend disputed general assemblies through counsel or a properly authorised representative.

14. What Should Be Written in the Opposition?

A simple statement such as:

“We oppose the decision.”

may be less useful than a properly reasoned objection.

Depending on the circumstances, the investor may record that:

• there is no genuine financing need;
• the amount of the capital increase is disproportionate;
• the transaction is intended to dilute minority shares;
• the shareholder’s pre-emptive rights have been unlawfully restricted;
• the proposed restriction lacks just cause;
• the transaction benefits the majority shareholder;
• insufficient financial information has been provided;
• the capital increase violates the equal treatment principle; and
• all legal rights, including annulment and interim-relief claims, are reserved.

This creates contemporaneous evidence showing that the investor objected before the consequences of the capital increase occurred.

15. Can the Court Stop the Capital Increase While the Case Is Pending?

Potentially, yes.

Merely filing an annulment action does not always provide sufficient practical protection.

If the transaction is implemented immediately:

• new shares may be issued,
• ownership percentages may change,
• voting control may shift,
• subsequent general assemblies may be held, and
• additional corporate transactions may follow.

TCC Article 449 therefore allows the court, after hearing the views of the board members, to order the suspension of implementation of the challenged general assembly resolution.

Depending on the circumstances, interim relief under general procedural law may also become relevant.

This is often one of the most important requests in a dilution dispute.

16. Annulment and Nullity Are Different

Not every defective capital increase resolution is merely “annullable.”

Article 447 provides that certain general assembly resolutions are null and void, particularly resolutions that:

• unlawfully restrict or eliminate indispensable shareholder rights,
• unlawfully restrict information and inspection rights,
• violate the fundamental structure of the joint stock company, or
• violate capital-protection rules.

The legal distinction between:

iptal — annulment

and

butlan — nullity

can affect the nature of the claim and applicable procedural analysis.

The correct legal characterisation should therefore be made after reviewing the specific defect.

17. What Happens in a Registered Capital System?

Not every capital increase in an A.Ş. is necessarily decided directly by the general assembly.

In companies using the registered capital system, the board of directors may be authorised to increase capital within the registered capital ceiling.

This changes the litigation route.

Under Article 460/5, shareholders and board members may challenge qualifying board resolutions on the grounds referred to in Article 445.

The deadline is significantly shorter:

One month from publication of the board resolution.

Article 460 also requires specific authority in the articles of association where the board is to issue privileged or premium shares or restrict shareholders’ new share subscription rights.

Foreign investors should therefore immediately determine whether the disputed increase resulted from:

a general assembly resolution

or

a board resolution under the registered capital system.

The difference may determine both the lawsuit and the deadline.

18. Board Resolutions May Also Be Null and Void

Article 391 allows a court to determine that certain board resolutions are null and void.

This includes, in particular, board decisions that:

• violate the equal treatment principle,
• conflict with the fundamental structure of an A.Ş.,
• violate the capital maintenance principle, or
• infringe or improperly restrict shareholders’ indispensable rights.

This provision may become relevant where the dilution results from actions taken at board level.

19. The Three-Month Registration Rule Should Also Be Checked

Capital increase procedures must also satisfy formal statutory requirements.

Under TCC Article 456, if a capital increase cannot be registered within three months from the relevant general assembly or board decision, the decision becomes ineffective under the statutory framework.

Therefore, lawyers reviewing a disputed transaction should examine not only the resolution itself but also:

• resolution date,
• registration date,
• Trade Registry Gazette publication,
• amended articles,
• subscription declarations, and
• implementation documents.

Technical defects can sometimes become as important as the substantive abuse allegations.

20. Previous Capital Must Generally Be Paid

Article 456 contains another important requirement.

Except for increases from internal resources, a company generally cannot increase its capital until the cash consideration of existing shares has been fully paid, subject to insignificant unpaid amounts relative to the capital.

Therefore, when reviewing the validity of a disputed capital increase, the investor should also examine:

• whether existing capital commitments were paid,
• whether majority shareholders still owed capital,
• whether the accounting records properly reflect payments, and
• whether the statutory requirements for the chosen capital increase method were actually satisfied.

21. Internal Resources Must Also Be Examined

Companies may increase capital through internal resources such as eligible reserves and funds.

Article 462 regulates capital increases from internal resources.

Where funds that legislation permits to be added to capital exist on the balance sheet, the relationship between those funds and a cash capital increase must be examined carefully.

This can matter in dilution litigation.

For example, the foreign investor may argue:

“The company already had sufficient internal funds capable of strengthening the capital. There was no commercial need to require shareholders to inject an enormous amount of new cash.”

That argument does not automatically invalidate the increase, but it may form part of the broader good-faith analysis.

22. What Documents Should the Foreign Investor Obtain?

A capital dilution dispute should be analysed from both corporate and financial perspectives.

The investor should preserve and review, where available:

• articles of association;
• shareholders’ agreement;
• investment agreement;
• current and historical Trade Registry Gazette records;
• general assembly invitations;
• agenda;
• general assembly minutes;
• attendance list;
• board resolutions;
• pre-emptive rights announcements;
• notifications sent to shareholders;
• board reports concerning restriction of pre-emptive rights;
• financial statements;
• balance sheets;
• shareholder loan records;
• bank records;
• capital payment documents;
• valuation reports;
• audit reports; and
• correspondence showing the background to the shareholder dispute.

Messages and emails exchanged before the capital increase may also be important.

For example, a message from the founder stating:

“If you do not sell your shares, we will increase the capital until your percentage becomes irrelevant”

could materially change the evidentiary assessment of the transaction.

23. Shareholders’ Agreements Can Provide Additional Protection

Foreign investors should not rely solely on statutory rights.

A well-drafted shareholders’ agreement can require the foreign investor’s consent before certain capital-related actions are taken.

Typical provisions may regulate:

• capital increases;
• issuance of new shares;
• creation of new share classes;
• restriction of pre-emptive rights;
• issuance of convertible instruments;
• employee share programmes;
• changes to share privileges;
• acquisition of another company through share issuance;
• mergers and demergers;
• related-party investments; and
• amendments to the articles of association.

These matters are commonly described as reserved matters.

For example, the shareholders’ agreement may provide:

“No capital increase may be undertaken without the affirmative vote of the foreign investor.”

The corporate-law effectiveness of such arrangements must be structured carefully, including whether protections should also be reflected in the articles of association.

24. Anti-Dilution Clauses Can Provide Additional Economic Protection

Investment agreements, particularly startup and venture capital agreements, may contain anti-dilution provisions.

These become especially relevant where new shares are later issued at a lower valuation.

Common contractual models internationally include:

• full-ratchet anti-dilution,
• weighted-average anti-dilution, and
• contractual adjustment mechanisms.

Their enforceability and implementation within a Turkish corporate structure must be analysed together with mandatory Turkish corporate law.

Nevertheless, they can provide valuable protection beyond the statutory pre-emptive right.

25. What About Limited Companies?

Foreign investors may also hold shares in a Turkish Limited Şirket (Ltd. Şti.).

Limited companies have their own statutory pre-emptive rights regime.

Under TCC Article 591, unless otherwise provided by the articles of association or the capital increase resolution, each shareholder generally has the right to participate in the capital increase in proportion to its existing shareholding.

Pre-emptive rights can only be restricted or removed where just cause exists.

The restriction must not unjustifiably benefit one person or unfairly disadvantage another.

Shareholders must also generally receive at least 15 days to exercise their rights.

26. Capital Increase in an Ltd. Şti. Requires a Qualified Majority

TCC Article 621 treats both:

• increasing the share capital, and
• restricting or removing pre-emptive rights

as important general assembly decisions.

These decisions generally require:

at least two-thirds of the votes represented at the meeting

and simultaneously

an absolute majority of the entire voting share capital.

This is an important distinction from ordinary limited-company resolutions.

27. Can an Ltd. Şti. Capital Increase Also Be Challenged?

Yes.

TCC Article 622 provides that the provisions governing nullity and annulment of A.Ş. general assembly resolutions apply by analogy to limited companies.

Accordingly, foreign investors in an Ltd. Şti. may also challenge abusive capital increase resolutions where the statutory conditions exist.

28. What if the Investor Was Given Pre-Emptive Rights but Cannot Afford to Participate?

This is commercially difficult but legally important.

Suppose:

Founder: 70%
Foreign Investor: 30%

The company genuinely requires EUR 5 million of additional capital.

The foreign investor therefore needs to provide EUR 1.5 million to maintain its 30% ownership.

The investor cannot or does not wish to invest the additional money.

The founder contributes the remaining capital.

The foreign investor’s shareholding decreases.

That result is not automatically unlawful.

A statutory pre-emptive right gives the investor the right to participate.

It does not ordinarily require the other shareholders to finance the investor’s participation.

This is why sophisticated foreign investors should negotiate funding and anti-dilution protections when the original investment is made.

29. What if the Capital Increase Is Designed to Push the Investor Below 10%?

This may be particularly significant.

In a non-public A.Ş., certain important statutory minority rights are linked to ownership of at least 10% of the share capital.

For example, Article 531 allows shareholders representing at least 10% of the capital in a non-public A.Ş. to request dissolution for just cause, although the court may order another appropriate remedy instead.

Consider:

Foreign investor before increase:

12%

Foreign investor after increase:

4%

If the surrounding evidence suggests the transaction was specifically designed to deprive the investor of statutory minority rights, this may strengthen arguments concerning abuse of majority power and violation of good faith.

The timing and commercial justification of the transaction become particularly important.

30. A Practical Litigation Strategy

A foreign investor discovering a potentially abusive dilution should act quickly.

The usual legal strategy may involve immediately determining:

First: What type of company is involved — A.Ş. or Ltd. Şti.?

Second: Was the increase decided by the general assembly or the board?

Third: What is the applicable litigation deadline?

Fourth: Was the investor’s pre-emptive right properly preserved?

Fifth: If it was restricted, what was the alleged just cause?

Sixth: Did the majority receive an economic or voting advantage?

Seventh: Was there a genuine financing need?

Eighth: Were corporate formalities complied with?

Ninth: Has the increase already been registered?

Tenth: Is urgent interim relief required to prevent implementation?

The litigation should generally be supported by a financial analysis rather than relying only on corporate-law arguments.

A court deciding whether a capital increase was abusive may need to understand why the company actually required the additional capital.

31. Practical Example

Assume a UK investor owns 25% of a Turkish technology A.Ş.

The founders hold 75%.

The company is profitable and has substantial cash reserves.

Relations between the founders and the UK investor deteriorate.

Two months later, the founders propose a capital increase equal to ten times the existing capital.

The foreign investor requests:

• financial justification,
• cash-flow projections,
• investment plans, and
• information concerning the intended use of funds.

The company refuses to provide meaningful information.

The founders then restrict the investor’s pre-emptive rights and allocate most new shares to a founder-controlled company.

After the increase, the UK investor’s stake would fall from 25% to 3%.

This would present several serious legal questions:

• Is there a genuine corporate reason for the capital increase?
• Why was such a large amount required?
• Was there just cause to restrict pre-emptive rights?
• Why were shares allocated to a founder affiliate?
• Was the foreign investor unfairly disadvantaged?
• Did the majority receive an unjustifiable benefit?
• Does the resolution violate equal treatment and good faith?
• Should implementation of the decision be suspended?

Depending on the evidence, the investor may have strong grounds to challenge the transaction.

32. Conclusion: Can Foreign Investors Stop an Abusive Capital Increase?

Yes, where the statutory conditions are satisfied.

Turkish law does not guarantee that a foreign shareholder’s ownership percentage will remain permanently unchanged.

If a company genuinely requires financing, properly approves a capital increase, preserves the shareholder’s subscription rights and treats all shareholders fairly, a foreign investor who does not participate may lawfully suffer dilution.

However, majority shareholders cannot use a capital increase as an unrestricted mechanism to eliminate or economically weaken the minority.

A foreign investor should consider challenging the transaction where there are indications of:

• absence of genuine financing need;
• disproportionate capital increase;
• unlawful restriction of pre-emptive rights;
• unequal treatment;
• unjustifiable benefit to the majority;
• manipulation of share value;
• violation of the articles of association;
• procedural irregularities; or
• abuse of majority voting power.

For an A.Ş. general assembly resolution, the ordinary annulment period is generally three months from the decision date.

For certain capital increase resolutions adopted by the board under the registered capital system, the challenge period may be only one month from publication of the resolution.

Accordingly, foreign investors should seek legal review immediately after becoming aware of a potentially dilutive capital increase.
