The dominant state of incorporation for United States (US)-domiciled companies is Delaware. The primary forms for business entities under Delaware law include C corporations (C Corps), S corporations (S Corps), limited liability companies (LLCs), limited partnerships (LPs), general partnerships (GPs) and limited liability partnerships (LLPs).
Publicly traded companies are typically C Corps. The primary features of a C Corp include:
An S Corp is similar to a C Corp, but may only be formed under certain conditions. To be registered as an S Corp, an entity must:
LLCs, LPs, GPs and LLPs are typically used by private entities. They are more versatile than corporations and have fewer corporate formalities. Tax treatment may vary – these entities generally receive pass-through tax treatment but may elect to be taxed as a corporation, depending on the specific corporation and the tax implications at play.
Investors’ choice of entity depends on a variety of factors, including tax treatment, corporate formalities, fiduciary duties, liability concerns and more. This guide will focus primarily on Delaware-based publicly traded companies, namely C Corps. Practice may vary for companies incorporated in other states and for private companies.
Foreign investors typically use the same entity forms as domestic investors, with one notable exception: generally, a foreign investor who is not a resident of the US may not invest in an S Corp. The choice of corporate entity depends on factors like:
The main classes of shares issued by Delaware corporations are common and preferred shares. Common shares typically give stockholders standard voting rights for corporate actions requiring stockholder approval. Preferred stockholders, on the other hand, are frequently granted no or only limited voting power, but are given preferential treatment over common stockholders for distributions (dividends on liquidation preference).
The rights of shareholders are set out in the governing documents of the corporation. The rights and preferences of classes of shares are described in a corporation’s charter, including any certificate of designation. While by-laws vary across corporations, standard by-laws for public corporations in Delaware outline the rights of stockholders related to stockholder meetings, voting, notice for certain corporate actions, and stockholder nominations of directors and other proposals of business, among other items.
Shareholder rights can vary based on the governing documents of a company or the terms of the authorised shares. Examples include dual-class shares, non-voting shares and preferred shares. With dual-class shares, one class is typically provided to company insiders, while another class is offered to the public. The shares offered to the public usually have much more limited voting rights in comparison to the class of shares retained by company insiders. This structure is particularly attractive to the founders of a company as it permits the sale of equity but limits the loss of control.
As discussed in 1.3 Types of Classes of Shares and General Shareholders’ Rights, preferred shares often provide shareholders with priority over common shares for company dividends and distributions, but frequently have no or limited voting rights.
Minimum share capital requirements vary by the state of incorporation; in Delaware, there is no minimum capital requirement for forming a corporation.
Under the Delaware General Corporation Law (DGCL), a corporation may issue one or more classes of shares and one or more series of shares within any such classes (DGCL § 151). LLCs in Delaware may also be formed with as few as one member.
S Corps require stockholders to be US citizens, permanent residents, or certain trusts, estates and exempt organisations. However, foreign investors may be stockholders or members of other entity types.
Stock exchanges have separate requirements for the minimum number of shares. For example, a company seeking to list on the New York Stock Exchange in connection with its initial public offering must typically have at least 400 holders of 100 shares or more and at least 1.1 million publicly held shares with a market value of at least USD40 million. Nasdaq generally requires that companies seeking to list on the Nasdaq have:
Shareholders’ agreements and joint venture agreements are commonly used in the context of private companies to delineate and clarify the economic and control rights of the respective parties.
In 2024, the DGCL was amended to expressly authorise stockholder agreements. Under DGCL § 122(18), corporations have the power to enter into certain contracts with one or more current or prospective stockholders. Without limiting what may be included in such agreements, the statute specifically permits a corporation to:
This amendment follows the Delaware Court of Chancery’s decision in West Palm Beach Firefighters’ Pension Fund v Moelis & Company, which struck down a stockholder agreement between a corporation and its founder. In Moelis, the court reaffirmed that the “business and affairs of every corporation... shall be managed by or under the direction of a board of directors”.
The trial court held that certain of the contractual rights granted to the controller conflicted with Section 141(a). The court recognised that its holding called into question certain elements of market practice, but reaffirmed that “a court must uphold the law, so the statute prevails”. In response to the trial court’s application of the statute, other parties in Delaware, including the Delaware Bar and the legislature, moved to pass amendments to DGCL § 122(18) to expressly permit stockholders’ agreements.
The precise contours of the amendments to DGCL § 122(18) are not yet fully clear. Commentators have observed that the amendments’ language reads broadly against the backdrop of Delaware law, which has traditionally balanced contractual flexibility with mandatory corporate requirements, and introduces new uncertainty. However, early decisions have begun to map its reach. In Masimo Corp. v Kiani, the Court of Chancery interpreted an executive agreement under the provisions of DGCL § 122(18) to override the requirements set forth under the corporation’s by-laws. The Court of Chancery enforced a California forum selection clause contained in the employment agreement of the corporation’s founder, former chief executive officer and alleged controller, requiring the breach of fiduciary duty and corporate waste claims to be litigated in California notwithstanding the corporation’s Delaware forum selection by-law. The Court of Chancery applied Moelis and concluded that the agreement at issue qualified as a governance agreement within the scope of DGCL § 122(18), rather than a mere employment contract, because the executive had entered into the agreement at least in part in his capacity as a controller and intra-corporate actor. The Court of Chancery also considered that the agreement constrained the board’s authority to manage the corporation’s affairs and constituted a lasting arrangement to allocate control rights over the long term.
Shareholders’ agreements can include a wide variety of terms based on the purpose and goals of the agreement. Such rights may include approval rights for:
These rights may also be conditioned upon action by the shareholder, such as maintaining ownership thresholds.
Shareholders’ agreements are typically enforceable and are frequently disclosed in the company’s public filings as material agreements.
Under Delaware law, a corporation is generally required to hold an annual meeting of stockholders, unless directors are elected by the written consent of stockholders. As such, the vast majority of Delaware public companies hold an annual meeting of stockholders. If an annual meeting is not held for a period of 30 days after the date designated for the annual meeting, or if no date has been designated and no meeting has taken place in the prior 13 months, then, upon the request of a stockholder or director, the Delaware Court of Chancery may order a meeting to be held.
Stockholders, as of a specified record date, must be given notice of the annual meeting. The notice must include the date, time and place (including the means of remote communication, if any), and the record date for determining stockholders entitled to notice of the meeting. Notice must be given no more than 60 days and no less than ten days prior to the date of the annual meeting. The board of directors must set the record date to occur no more than 60 days and no less than ten days prior to the date of the annual meeting. A corporation’s governing documents may set forth additional requirements for notice for a stockholder meeting.
At the annual meeting, stockholders elect directors to the board of directors. Stockholders may vote on additional proposals, including the ratification of auditors and approval of executive compensation on an advisory basis. Stockholders may also vote on other proposals put forth by the board of directors or stockholders, including the amendment of governing documents, approval of stock issuances and non-binding proposals on a variety of subjects.
It is not typical to hold more than one meeting of stockholders per year. Corporations may call special meetings of stockholders to seek stockholder approval of certain matters outside of the regular annual meeting cycle.
Corporations’ governing documents typically permit the board of directors to call a meeting of shareholders. Governing documents may provide for other individuals to call a meeting of shareholders, such as the chairperson of the board or the chief executive officer.
While there is no statutory right for stockholders of Delaware corporations to call a special meeting, the governing documents of a corporation may give stockholders such right, contingent on compliance with certain ownership and procedural requirements. Certain other state statutes grant shareholders the right to call special meetings directly.
Special meetings are typically called by the board of directors to approve certain matters (eg, a merger, stock issuance in connection with a business combination, domestication and other extraordinary transactions). Shareholders, in contrast, may call a special meeting as part of an effort to influence a corporation’s control and strategic direction (eg, a campaign to remove and replace directors by an activist or hostile bidder).
Procedures for calling a special meeting of shareholders are often specified in a corporation’s by-laws or certificate of incorporation.
Shareholders generally rely on the filings required under federal securities laws – primarily the company’s annual report filed on Form 10-K and the proxy statement filed on Schedule 14A, which includes information on the company, corporate governance practices, executive and director compensation, and the proposals subject to a shareholder vote at the meeting.
Under Delaware law, stockholders are entitled to examine the list of stockholders entitled to vote at a stockholder meeting during the ten-day period ending on the day prior to the meeting date.
Delaware law permits corporations to hold stockholder meetings virtually.
Delaware law requires that quorum consist of no less than a third of shares entitled to vote at the meeting. Otherwise, the certificate of incorporation or the by-laws may set the quorum requirements. In the absence of any specifications, Delaware law will generally require that a majority of shares entitled to vote will constitute a quorum.
A company’s certificate of incorporation or by-laws may set requirements for a resolution to pass. For instance, the voting standard for the election of directors may be a majority of outstanding shares, a majority of shares present or a plurality voting standard (ie, the election of directors who receive the highest number of votes).
In certain instances, the relevant threshold may be set by statute. As one example, the removal of directors generally requires the approval of the majority of outstanding shares.
Matters requiring shareholder approval include:
Voting standards vary, frequently requiring the approval of a majority of outstanding shares present at the meeting or a majority of outstanding shares. Some companies’ governing documents mandate supermajority voting requirements for certain matters, such as to approve charter and by-law amendments. For the election of directors, the default vote standard is the plurality of shares, which can be modified in the organisational documents to a majority-vote standard.
Shareholders are able to vote at the shareholder meeting or may vote via proxy. Shareholders commonly vote their shares electronically prior to the meeting through an electronic online platform, although paper and phone voting options are sometimes available.
Under Rule 14a-8 of the Securities Exchange Act of 1934, as amended, shareholders may be entitled to submit a proposal to be considered at a shareholder meeting and to be included in the company’s proxy statement. A shareholder must meet ownership requirements by holding shares worth at least USD2,000 of the company’s market value for the prior three years, USD15,000 for two years or USD25,000 for one year. The shareholder must then provide a written statement that they intend to hold the requisite amount of securities, and a written statement offering to meet with the company regarding the proposal. The proposal must be received at the company’s head office at least 120 days before the date the proxy statement was released for the prior year’s annual meeting or, in certain cases, for a reasonable period before proxy materials are sent for special meetings.
A company may exclude a proposal made under Rule 14a-8 from its proxy statement on various bases, including:
In 2025, the Division of Corporation Finance (the “Staff”) of the US Securities and Exchange Commission (the “Commission”) issued guidance that the Staff will take a “company-specific approach” to determine whether a proposal relates to a significant policy issue, rather than focus on whether a proposal has a “broad societal impact” or universally significant issues. The Staff also reinstated prior guidance that proposals seeking “intricate detail or specific timeframes or methods for implementing complex policies” or that are “highly prescriptive” are excludable as micromanaging the company.
In a landmark announcement in November 2025, the Staff announced that, for the 2025–2026 proxy season, the Staff would no longer respond to no-action requests nor evaluate companies’ intended reliance to exclude shareholder proposals under Rule 14a-8, other than requests asserting that a proposal is improper under state law. In August 2026, the Staff eliminated that exception and announced that it would discontinue responding to no-action requests entirely. In certain instances in the 2026 proxy season, proponents facing a company’s exclusion of shareholder proposals filed lawsuits seeking judicial review of the validity of the exclusion. Such proponents were often focused on environmental and social issues. In most such cases, the companies had excluded the shareholder proposals based on Rule 14a-8(i)(7)’s “ordinary business” exclusion, and only one exclusion was based on procedural defects.
Alternatively, a shareholder owning at least one share may submit a proposal via the process set forth in the company’s by-laws. However, companies are not typically required to include a proposal submitted under the by-laws in their proxy statements and proxy cards disseminated to shareholders; as a result, such proposals are significantly rarer than Rule 14a-8 proposals.
Shareholders can make certain procedural challenges to resolutions passed at a shareholder meeting. Resolution of such challenges depends on the circumstances at issue, as well as applicable Delaware law and the company’s certificate of incorporation and by-laws.
Meetings must be called in compliance with Delaware law and the company’s certificate of incorporation and by-laws. Procedural defects related to an annual or special meeting of stockholders may include:
Notice
See 2.1 Types of Meeting, Notice and Calling a Meeting.
Quorum
See 2.5 Quorum, Voting Requirements and Proposal of Resolutions.
Improper Authority to Call a Meeting/Improper Chair
An annual meeting should be called in the manner provided in the by-laws (DGCL § 211(b)). Typically, a corporation’s by-laws will stipulate that the board of directors is the proper party to call an annual meeting or shareholder meeting. In addition, corporate by-laws typically outline who may act as chairperson of the annual meeting. In many cases, this person is the president or chairperson of the corporation or another member of the board.
Improper Vote Count
A shareholder may raise an objection to the manner in which votes were counted by the inspector of election at the annual meeting.
Remedies
DGCL § 225 provides a mechanism to determine the validity of any director election or other stockholder vote. If the Court of Chancery determines that the stockholder vote was not validly held, it may order that a new vote be held or award other equitable relief appropriate under the circumstances.
In addition, common law bases for action may enable stockholders to challenge stockholder votes passed at a meeting for failure to comply with statute or the corporation’s governing documents.
Institutional investors influence a company’s actions via exercising voting rights as shareholders and via ongoing engagement. Institutional investors often hold large stakes in public companies, giving them considerable voting power at shareholder meetings. Institutional investors are thus able to communicate approval or disapproval of director performance via voting. Even in uncontested elections of directors, institutional investors may withhold votes on directors and vote against management on other proposals, such as executive compensation proposals, to demonstrate dissatisfaction. Institutional investors also play influential roles in whether shareholder proposals pass.
Beyond exercising the shareholder franchise, institutional investors can guide companies through direct engagement and issuing broader policy documents, including voting policies. These policies can influence action by boards and management.
Proxy advisers play influential roles in assisting in monitoring corporate governance practices and making influential recommendations that can impact the vote of institutional investors. While larger institutional investors may have in-house governance teams to assess corporate performance and governance, many institutions leverage recommendations and research reports issued by proxy advisers such as ISS and Glass Lewis to guide their votes at shareholder meetings.
Shareholders holding shares via a nominee, such as a brokerage firm, must follow the procedures of the nominee in order to vote shares. Information related to matters to be voted at a shareholder meeting would be available via a public filing submitted by the company and thus available to holders of shares via nominees.
Under Delaware law, stockholders may approve a resolution by written consent, unless otherwise specified in the corporation’s certificate of incorporation. Where action by written consent is permitted, the applicable voting standard is typically the minimum number of votes to take such action at a stockholder meeting. Company by-laws may specify further procedures for stockholder action by written consent.
Under Delaware law, existing stockholders do not have the pre-emptive right to subscribe to an additional issue of shares, unless such right is granted in the corporation’s certificate of incorporation (DGCL § 102(b)(3)).
As a general matter, there are no broadly applicable legal or regulatory restrictions on the transfer or disposal of shares for public companies. Government authorities may impose restrictions on stock transfer for certain regulated entities, such as utilities or banks. In addition, in recent years, antitrust considerations have grown across wide swathes of the economy.
Shareholders are generally entitled to grant security interests over their shares.
Companies generally cannot require the disclosure of a shareholders’ interest.
However, securities laws do require disclosure under certain circumstances. For example, institutional investors managing over USD100 million must file Form 13F with the Commission on a quarterly basis, which provides insight into such investors’ stock holdings. Investors must also file a Schedule 13D (active investment) or Schedule 13G (passive investment) if they directly or indirectly acquire the voting or investment power of over 5% of a voting class of company stock.
In addition, shareholders may be required to file a notification under an antitrust statute – the Hart–Scott–Rodino Act of 1976, as amended – to disclose stakes above a certain dollar threshold, which is adjusted annually by the Federal Trade Commission (set at USD133.9 million for 2026). A shareholder may be exempt from such notification requirements if the share purchase is made solely for the purpose of investment, and the total stake remains at or below 10% of the company’s outstanding shares.
Under Delaware law, a corporation may retire shares that were previously issued if they are not currently outstanding. This may occur after a corporation acquires its own shares through a repurchase, redemption, conversion or exchange.
By default, a retired share may be reissued by the corporation at a later date. If, however, the corporation’s certificate of incorporation specifically forbids their reissue, then a certificate identifying such shares must be filed. This filing has the effect of amending the certificate of incorporation to reduce the total number of shares authorised to the retired shares’ class (DGCL § 243).
Delaware public companies are allowed to buy back their shares, but must comply with certain requirements to ensure that they do not inadvertently become subject to market manipulation claims. Rule 10b-18, under the Securities Exchange Act of 1934, as amended, provides companies with a safe harbour to purchase shares of common stock. To qualify under the rule, a company’s open-market repurchases must be made by the company itself or by no more than one repurchase agent per day. In addition, the company cannot repurchase shares at the very beginning or end of a trading day, and repurchases must be made at a price no higher than the highest of either:
The company’s daily repurchases must not exceed 25% of the average daily trading volume of the prior four weeks.
In addition to the Rule 10b-18 requirements, a company repurchasing its shares may also be subject to an excise tax on such repurchases, equal to 1% of the aggregate fair market value of the shares repurchased.
A Delaware corporation is permitted to pay dividends to stockholders out of the corporation’s surplus, or out of its net profits if no surplus exists. As such, if neither a surplus nor net profit exists, a corporation generally may not pay dividends to stockholders (DGCL § 170).
To declare a dividend, the corporation’s directors must generally fix a record date to determine which stockholders are entitled to receive such dividend. This date should be within 60 days of the payment of the dividend. Moreover, the record date must be a date on or after the day the corporation acts to fix such date.
While shareholders generally elect or remove directors to the board of a company via a shareholder vote at the company’s annual meeting, there are other means by which shareholders can elect or remove directors. For example, the by-laws or certificate of incorporation may provide shareholders with the right to call a special meeting or act by written consent for the purposes of removing directors and electing replacements. The company’s governing documents will often set forth the procedure for taking such action.
As a general proposition, shareholders can challenge decisions of directors in court by citing statute, the company’s governing documents and fiduciary duties under common law, among other reasons. The resolution of such challenges depends on the circumstances at issue, as well as applicable Delaware law and the company’s certificate of incorporation and by-laws.
To require directors to take (or not take) action, a shareholder typically seeks injunctive relief, predicated on the likelihood of success of the claim that directors breached their obligations or another basis for action (eg, a contractual obligation). Shareholders would likely seek to obtain a preliminary injunction to secure temporary relief, and then seek to proceed to trial for a permanent injunction. Obtaining an injunction is a three-part test:
Despite having the potential remedy of injunctive relief, there are meaningful hurdles to bringing such claims, including:
The business judgement rule is a presumption that directors acted independently, with due care, in good faith and in the honest belief that their actions were in stockholders’ best interests. A plaintiff bears the burden of rebutting this presumption. Thus, a stockholder plaintiff generally would need to allege, and later prove, facts sufficient to rebut this presumption.
Generally, public companies include a voting item at their annual meeting requesting that shareholders ratify the appointment of a designated auditor. The results of the shareholder vote are typically viewed as advisory.
Public companies (and therefore their boards) are required to report certain corporate governance arrangements. While there are a variety of situations where disclosure may become required, the most common vehicles for corporate governance disclosures are a public company’s annual report and proxy statement. In these filings, public companies provide detailed information on the board of directors, corporate governance practices and other policies.
Controlling stockholders owe fiduciary duties. Both the Delaware common law and statutory law bear on when a stockholder will be treated as a controller and on how transactions involving a controller are reviewed. In 2025, Delaware substantially revised the statutory framework governing these questions, and the courts have since begun to apply and test the new statutory framework.
Controllers’ common law fiduciary duties remain the analytical baseline where a safe harbour under the DGCL § 144 amendments is either unavailable or not invoked. Delaware courts have long held that a controlling stockholder does not owe a duty to “engage in self-sacrifice for the benefit of minority stockholders” (In re Synthes, Inc S’holder Litig.). The Court of Chancery, moreover, has refined the scope of these duties. In 2024, it concluded that “a controller does not owe any enforceable duties when declining to vote or when voting against a change to the status quo”, but “owes limited yet enforceable duties” when it votes to “change the status quo” (In re Sears Hometown and Outlet Stores, Inc S’holder Litig.). The court further concluded that, “if the majority stockholder seeks to change the status quo, then the majority controller cannot harm the corporation knowingly or through grossly negligent action”. At the same time, though, the court held that “when exercising stockholder-level voting power, a controller owes a duty of good faith that demands the controller not harm the corporation or its minority stockholders intentionally”.
The Delaware Supreme Court has also clarified when a minority stockholder will be treated as a controller. General control requires “potent voting power and management control”, whereas transaction-specific control requires that the stockholder must have exercised actual control during the course of the challenged transaction (In re Oracle Corporation Derivative Litigation).
In March 2025, the Delaware General Assembly amended DGCL § 144 to provide statutory definitions of “controlling stockholder” and “control group”, and to create safe harbour procedures for conflicted transactions involving controllers. The amendments took effect on 25 March 2025 and apply both prospectively and retroactively, subject to a carve-out for actions or proceedings commenced, completed or pending on or before 17 February 2025.
Under amended DGCL § 144, a controlling stockholder of a corporation is generally a person or entity who, together with its affiliates and associates, either:
A “control group” arises where two or more stockholders that are not individually controlling stockholders are bound, by an agreement, arrangement or understanding, to act together as a controlling stockholder.
The amendments also establish safe harbour “cleansing” mechanisms for conflicted transactions involving controlling stockholders and/or control groups. Most conflicted controller transactions are cleansed if the transaction is approved or recommended by either:
This “either/or” structure is a meaningful departure from prior common law practice, which for controller squeeze-outs generally required both protections in order to cleanse a challenged transaction. For controlling stockholder going-private transactions, however, both cleansing mechanisms remain necessary to obtain safe harbour protection. Absent a qualifying safe harbour, a conflicted-controller transaction remains subject to review under the exacting “entire fairness” standard.
The constitutionality of the DGCL § 144 amendments (and, in particular, their retroactive reach) was promptly challenged. In Rutledge v Clearway Energy Group LLC, the Delaware Supreme Court upheld the amendments against two constitutional challenges that the Court of Chancery had certified. The Rutledge decision thus confirmed that amended DGCL § 144 governs conflicted-controller transactions going forward.
In June 2026, the Delaware Court of Chancery issued its first ruling on DGCL § 144’s disinterested director safe harbour, in Ayers v Foley. The Delaware Court of Chancery determined that a claim warranted dismissal where the plaintiff failed to plead particularised facts evidencing a “disabling conflict” and support a reasonable inference of a conflicted transaction.
As a threshold matter, “insolvency” has different meanings in different contexts and, broadly speaking, shareholder recoveries and rights may depend on whether a company is insolvent under:
The result is that a company can be technically insolvent but nonetheless hold long-term value for shareholders, particularly where said company is balance-sheet solvent but cash-flow insolvent. Therefore, shareholders can and should stay apprised and cognisant of how insolvency is being measured, particularly when a company enters into Chapter 11 proceedings or other in-court processes.
Once a company has entered into insolvency proceedings, such as Chapter 11 cases, if there is a path to long-term value, shareholders may find it advantageous to organise an equity committee to specifically pursue the equity’s interests. The key consideration here is cost: absent being designated an “official equity committee” by the bankruptcy court – which is, as more than one judge has put it, “the rare exception” (see, eg, In re Williams Commc’ns Grp., Inc, 281 B.R. 216, 223 (Bankr. S.D.N.Y. 2002)) – or proving that the committee has made a “substantial contribution” to the case (see 11 USC §§ 503(b)(3)(D), (b)(4)), professional fees for equity committee representatives, such as counsel and financial advisers involved in bankruptcy court litigation, will be the direct financial responsibility of committee members.
In conjunction with or in the absence of a path to long-term value, shareholders also have the ability to assert rights against directors and officers in both derivative and direct claims – a path that is potentially clearer following the Supreme Court’s recent decision invalidating non-consensual third-party releases in Purdue Pharma (see Harrington v Purdue Pharma L. P., No. 23-124, 2024 WL 3187799 (US 27 June 2024)). Even in bankruptcy cases where there is no remaining value in the company itself, courts may permit and/or companies may consensually agree to pursue certain claims to the extent of available D&O insurance, thereby allowing shareholders to tap an alternative source of recovery. Shareholders can and should consult with restructuring or bankruptcy counsel relatively early in the process in order to fully understand paths to recovery via D&O claims in an insolvency or Chapter 11 scenario.
It is important to note that, in Purdue Pharma, the Court held only that the Bankruptcy Code does not authorise non-consensual releases of claims against non-debtors. In the wake of that decision, plan proponents have increasingly relied on opt-in or opt-out mechanics to establish consent, and the lower courts have continued to hold unique views as to what constitutes valid consent. One potential effect of Purdue is that direct claims against directors, officers and other non-debtors are less likely to be extinguished by a plan without the claimant’s consent, thus preserving avenues of recovery, including those against available D&O insurance, that a broad, non-consensual release might previously have foreclosed. Again, however, companies should engage restructuring or bankruptcy counsel early to assess how any proposed releases, and the associated consent mechanics, potentially bear on their claims.
Shareholders may claim that directors, officers or other fiduciaries breached their fiduciary duty to shareholders. These claims can take two forms: direct and derivative.
A direct suit is a claim made by a shareholder directly against a director or officer who has allegedly breached a fiduciary duty owed to shareholders, leading to actual injury to the plaintiff. A derivative suit is a claim made by a shareholder on behalf of the company.
Courts distinguish between direct and derivative suits by evaluating two factors:
In a direct suit, the shareholder has been directly harmed; as such, the shareholder is entitled to damages. In a derivative suit, on the other hand, the company has been harmed and is, therefore, the entity entitled to relief.
Importantly, the pleading standard for a derivative suit is more onerous than the pleading standard for a direct suit. Under the applicable rules, a derivative complaint must do both of the following:
In some cases, shareholders may name the company as a party to an action concerning alleged breaches of duties to achieve relief that would not be possible without the company (eg, as a nominal defendant in a derivative action).
See 10.1 Remedies Against the Company.
See 10.1 Remedies Against the Company.
Shareholder activism operates under a multi-part legal framework encompassing the following.
Activists leverage a variety of legal tools to pursue their objectives. While the specific mechanisms vary by situation, activists can:
Activist shareholders typically have primarily economic goals in pursuing a campaign. Activist demands frequently include the following.
Activists commonly use a variety of strategies to pursue change at a target company. These strategies can be categorised as follows.
Stakebuilding
Typically, the activist will build a stake in the company in secret, including by acting in concert with other shareholders or utilising derivative instruments. An activist may be required to disclose its stake eventually due to required Form 13F, Schedule 13D/G and Hart–Scott–Rodino filings (see 3.4 Disclosure of Interests).
Engagement
Typically, an activist first attempts to engage privately with the management and board of a target company before making any public demands. For example, the activist may send a private letter to company leadership calling for a specific course of action and requesting a meeting with senior leadership and/or board members.
Public Pressure
In other situations, an activist may immediately lead with a press release, including an open letter to the board or shareholders, setting forth concerns and a specified plan of action. Activists may release white papers and presentations outlining their investment theses and demands. Such steps often coincide with the first public disclosure of the activist’s position in the company.
Proxy Contest
An activist may nominate director candidates for election to the target company’s board and/or submit other shareholder proposals at the next annual shareholder meeting.
An activist can also ask shareholders to take similar actions at a special meeting of shareholders or via action by written consent, to the extent permitted by applicable state law and the target company’s governing documents.
Litigation/Books-and-Records Demands
Books-and-records demands by activists have increased in frequency in recent years, enabling activists to obtain access to certain confidential corporate records. In Delaware, a stockholder must demonstrate a “proper purpose” to succeed in such demand.
In 2025, Delaware’s General Assembly amended DGCL § 220 to define the books and records subject to inspection. Such books and records are now defined to be a set of identified core materials, such as board minutes, board materials and any agreement entered into under DGCL § 122(18).
Furthermore, the Court of Chancery may order the production of other, additional records, “only if”:
DGCL § 220, as amended, expressly allows corporations to redact portions of any produced books and records to the extent such portions contain information that is not related to the stated purpose of the stockholders’ inspection demand. The as-amended statute further allows corporations to require the stockholder to enter into a confidentiality agreement as a condition to the production of books and records, as well as an agreement that the produced books and records be deemed incorporated by reference in any complaint filed by or on behalf of the stockholder in relation to the subject matter referenced in the demand.
Shareholder activism is an ever-present reality for US companies. Activists typically target companies with perceived shortfalls in performance or governance. The threat applies to companies across market caps. Size has not been a barrier to activists, as companies with a market capitalisation of more than USD100 billion have faced prominent campaigns.
Following the Trump administration’s announcement of reciprocal tariffs in April 2025, global markets faced the largest decline since the onset of COVID‑19, as the prospect of major US import levies disrupted supply chains and heightened inflationary risks. Tariff uncertainty and volatility stemming from the conflict with Iran may have delayed near-term M&A decisions in H1 2026. Nonetheless, overall activism levels increased compared to 2025, and campaign activity remained elevated compared to 2020 through 2023, demonstrating the structural resiliency of shareholder activism despite ongoing market turbulence.
Amid a looser federal regulatory environment and greater openness to deal making in the near to medium term, activists have increasingly embraced M&A-focused theses, urging break-ups or strategic review processes at companies across a variety of industries, including financial services, healthcare and technology. Alongside this shift, companies should pressure-test existing strategies and prepare for demands to conduct one-off strategic reviews.
Companies should engage with advisers to proactively take steps to identify, eliminate or mitigate weaknesses and address concerns from the broader investment community. In some cases, it may be appropriate to develop and disclose a governance transition plan to align with investor expectations.
Hedge funds are typically the drivers of activism in the USA. There is a significant ecosystem of funds raising capital based on the notion that active engagement can deliver superior returns uncorrelated with the broader market. These funds have developed various reputations along the spectrum of activism.
The most prominent activist funds frequently engage in public, high-pressure fights. These activists’ agendas are more likely to include M&A, such as the sale of an entire company or certain divisions, and other means of quickly returning value to shareholders such as stock buybacks. Newer funds may be further incentivised to take aggressive and well-publicised positions in order to build stature among the investor community. Even more established funds will use aggressive campaigns to reaffirm their “fearsome” reputation.
Other funds have focused on private engagement and may see themselves as “constructivists” aligned with long-term shareholders. Such investors typically focus on longer-term strategic and operational changes, with an eye towards building a sustainable business. These funds may develop more collaborative relationships with companies, straddling the line between activists and advisers.
Institutional or other traditional large shareholders are unlikely to publicly lead an activism campaign. This tendency has solidified in recent years as institutions have evolved further into “passive” products that track the broader market or a specific index, and away from “active” products that select specific companies for investment.
Nonetheless, institutional investors continue to show a willingness to vote for activist nominee director slates or shareholder proposals.
Many activist engagements remain private; as such, the universe of public information does not incorporate the full scope of demands.
Based on public data, in 2025, activists agitating at US companies sought 214 board seats and obtained 145 board seats. In the first half of 2026, activists sought 78 board seats and obtained 64 board seats. These board seats were largely obtained through settlements and not by shareholder vote.

Specialist legal advisers can provide recommendations on “best-in-class” improvements to governance practices and documents. Financial advisers can help boards assess activists’ typical financial theses, such as increased capital return and M&A options.
Consistent responsiveness to shareholders can prevent a future campaign, where:
The board should engage in regular self-assessment to ensure effective composition and function, given:
After one or more activists approach the company, the course of action depends on the particular context and circumstances. In general, a company should take the following steps:
These steps can help a company regain the initiative, particularly as activists often use the element of surprise as leverage to force preferred outcomes.
