Shareholder activism has become one of the defining features of the modern US public company landscape. Activist investors — ranging from large hedge funds with billions of dollars in capital to individual shareholders armed with social media and the SEC’s proxy rules — challenge corporate strategy, governance practices, executive compensation, capital allocation, board composition, and environmental and social policies with increasing frequency and sophistication. For boards that have not experienced an activist campaign, the question is not whether it will happen, but when. And the time to prepare for an activist is long before one appears on the shareholder register, not after a Schedule 13D hits the SEC’s EDGAR system.

Shareholder activism takes many forms, and the appropriate board response depends significantly on the nature of the activism and the underlying merits of the activist’s position. Financial activists — typically hedge funds — seek to unlock what they perceive as undervalued stock through changes in capital allocation (share buybacks, special dividends, asset sales), strategic direction (divestitures, spin-offs, going-private transactions), or leadership (management and director changes). Governance activists focus on board composition, executive compensation, and structural governance features such as classified boards, supermajority voting requirements, and dual-class share structures. Environmental, social, and governance (ESG) activists seek changes in the company’s policies on climate, diversity, labor practices, and related matters. Understanding the type and motivation of activism is the first step toward formulating an appropriate response.

The Mechanics of a Proxy Contest

A proxy fight — sometimes called a proxy contest or proxy battle — is a campaign by one or more shareholders to obtain the votes of other shareholders to elect directors, adopt resolutions, or otherwise direct corporate action over the opposition of the incumbent board. Proxy contests are one of the most powerful tools available to activist shareholders, because they can fundamentally change the composition of the board and the direction of the company without requiring the acquiror to pay an acquisition premium. They are also extraordinarily expensive, disruptive, and time-consuming for both sides.

In a director election proxy contest, the activist nominates its own slate of director candidates and solicits proxy votes from other shareholders in favor of those nominees, in competition with the incumbent board’s slate. For many years, the rules governing this process disadvantaged activist nominees: the company could include its own director nominees in its proxy statement (the white card) at company expense, while the activist had to file and distribute a separate proxy statement (the blue card) at the activist’s expense. This proxy access asymmetry created a meaningful structural advantage for incumbents, particularly in contests involving smaller companies where the cost of a full proxy campaign could be prohibitive for all but the largest activist funds.

Universal Proxy Rules: A Game-Changing Reform

The SEC adopted universal proxy rules in 2022, effective for annual meetings held after August 31, 2022, that fundamentally altered the proxy contest landscape. Under the universal proxy rules, both the company and any nominating shareholder must include all duly nominated director candidates on their respective proxy cards. This means that shareholders voting by proxy can now mix and match among both the company’s nominees and the activist’s nominees on a single card — the same choice that shareholders attending the annual meeting in person had always had. Prior to the universal proxy rules, a shareholder voting by mail or through a broker had to choose between the company’s full slate (white card) and the activist’s full slate (blue card), with no ability to split their votes.

The practical consequences of universal proxy have been significant. Because shareholders can now vote for individual nominees from either slate, activists no longer need to run a full-board takeover campaign to achieve their goals — they can run a short slate of two or three nominees and have a realistic chance of electing those nominees even without a majority of shareholder support for replacing the entire board. This has lowered the cost and increased the frequency of director election proxy contests, particularly short-slate campaigns targeting one or two board seats. Boards and governance counsel have been recalibrating defensive strategies and engagement approaches in light of the universal proxy reality.

To nominate candidates under the universal proxy rules, an activist must provide the company with advance notice of its nominees that satisfies both the applicable timing requirements of the company’s advance notice bylaws and the SEC’s procedural requirements, which include a notice to the company at least 60 days before the meeting. The activist must also solicit proxies from at least 67 percent of the voting shares and must include a prominent legend in its proxy materials stating that it is using a universal proxy card. These procedural requirements provide the board with valuable early warning of an impending proxy contest.

Advance Notice Bylaws

Advance notice bylaws require shareholders who wish to nominate directors or propose other business at an annual or special meeting to provide the company with advance notice of their intentions — typically 60 to 120 days before the meeting — and to supply specified information about the proposed nominee or business and the proposing shareholder. These provisions serve legitimate governance purposes: they give the board and other shareholders time to evaluate proposed nominees and shareholder proposals before voting, and they ensure that the proxy materials distributed to shareholders contain complete and accurate information. They also give companies early warning of impending proxy campaigns, allowing time to develop a response strategy.

Delaware courts have consistently upheld advance notice bylaws that impose reasonable procedural requirements on nominating shareholders, while striking down provisions that are facially reasonable but applied in a manner that interferes with the shareholder franchise or that are adopted or amended specifically to block a particular activist’s campaign. The Delaware Court of Chancery and the Delaware Supreme Court have in recent years scrutinized advance notice bylaw amendments adopted during a pending proxy contest with particular skepticism, finding several such amendments to be improper attempts to manipulate the electoral process. Boards should ensure that their advance notice bylaws are reviewed by experienced governance counsel and that any amendments are made well in advance of any contemplated contest, for legitimate governance reasons that can be articulately defended.

Preparing for Activism: The Vulnerability Assessment

The single most effective thing a board can do to prepare for shareholder activism is to conduct a rigorous, honest vulnerability assessment before an activist appears. A vulnerability assessment asks the same questions that a sophisticated activist would ask: Is the company’s stock trading at a discount to peers or to intrinsic value? Does the company have underperforming business segments that could be divested to improve total shareholder return? Is capital allocation optimal — is the company hoarding cash or carrying excessive leverage? Is executive compensation well-structured and aligned with performance, or is it defensively easy to attack? Is the board composition diverse, independent, and skilled for the company’s current strategic situation? Are there governance features — a classified board, a supermajority amendment threshold, a poison pill — that institutional shareholders or proxy advisors routinely criticize?

Companies that identify their vulnerabilities before an activist does are in a position to address them proactively — either by making substantive changes (the best outcome) or by developing well-prepared defenses (a less satisfying but sometimes necessary outcome). Boards that discover their vulnerabilities only after receiving an activist’s public letter are perpetually on the back foot, responding to an agenda set by the activist rather than leading from a position of strength. A vulnerability assessment should be conducted at least annually, updated whenever there is a significant change in the company’s performance, shareholder base, or strategic situation, and taken seriously by the full board — not just the governance committee.

Defensive Measures: Poison Pills and Related Devices

Shareholder rights plans — commonly known as poison pills — are rights agreements that trigger when a shareholder acquires more than a specified percentage of the company’s shares (typically between 10 and 20 percent) without board approval, resulting in substantial dilution of the triggering shareholder’s stake. Poison pills are not primarily used to prevent proxy contests (they do not impede voting campaigns), but they are used to prevent an activist or acquirer from acquiring a controlling stake in the company’s shares in advance of a proxy campaign, which would give the activist disproportionate leverage.

Delaware courts apply the Unocal enhanced scrutiny standard to poison pill adoptions: the board must show that it reasonably perceived a threat to corporate policy and effectiveness, and that the pill is a proportionate, non-preclusive, and non-coercive response to that threat. Short-duration pills adopted in response to a specific identified threat are more easily defensible than longer-duration pills adopted without a specific justification. Institutional Shareholder Services (ISS) and most institutional investors are skeptical of standing poison pills, and boards that adopt them without shareholder approval frequently face negative vote recommendations. ‘Shareholder-approved’ rights plans — those submitted to a shareholder vote within a specified period of adoption — address the governance concerns while preserving the protective function.

Engaging with Activists

Many proxy contests are avoided or resolved through negotiation. Activist investors, like all investors, prefer to achieve their objectives without the cost and disruption of a contested election. And companies, even those with strong governance and defensible strategies, often find that the activist has identified real issues worth addressing. The most successful board responses to activism typically involve a willingness to listen and engage — not to capitulate reflexively, but to conduct a genuine assessment of the activist’s arguments and to respond substantively where those arguments have merit.

Engagement should be structured carefully. The company’s investor relations officers and senior management typically handle initial contact with activists, but the board should be briefed promptly when any significant activist position comes to the company’s attention. Outside counsel experienced in activist defense should be retained early — ideally before an activist emerges, as part of ongoing governance preparedness. Proxy advisory firms (ISS and Glass Lewis) should be engaged proactively: both firms have engagement programs that allow companies to present their governance story directly, and a company that has already engaged with ISS on its governance profile is better positioned to respond when ISS evaluates an activist’s campaign.

Settlement agreements that resolve proxy contests often involve the activist’s right to designate one or more board nominees, accompanied by a standstill agreement under which the activist agrees not to launch further campaigns for a specified period, not to acquire shares above a specified threshold, and not to publicly criticize the company. These settlements can be valuable for both sides, but they require careful structuring to ensure that the designated nominees are genuinely independent (not simply the activist’s puppets), that the standstill terms are reasonable, and that the governance changes agreed to as part of the settlement are consistent with the company’s long-term interests. Board seats are the most significant concession a company can make in an activist settlement, and the governance implications — including the nominee’s access to confidential information, their potential conflicts of interest, and their impact on boardroom dynamics — must be carefully evaluated before any agreement is reached.

The best long-term defense against shareholder activism is sustained, superior performance and a shareholder base that believes in the board’s strategy and execution. No governance defense mechanism, no advance notice bylaw, and no poison pill substitute for a board and management team that are genuinely creating value, communicating clearly with shareholders, and governing the company with integrity and skill. Boards that invest in understanding their shareholders’ perspectives — through regular investor relations engagement, proactive proxy season outreach, and honest vulnerability assessments — are far more resilient in the face of activism than those that treat shareholders as an obligation to be managed rather than owners to be served.
