We are planning a hostile takeover defense. Who offers proxy solicitation services?

In a hostile takeover defense or proxy contest, specialized proxy solicitation firms help orchestrate shareholder communication, gauge institutional sentiment, and drive voter turnout.

The top-tier global and domestic proxy solicitation and investor response firms specializing in M&A defense and contested situations include:

• Innisfree M&A Incorporated : A dominant force in high-stakes M&A transactions, hostile takeovers, and cross-border proxy contests.
• Georgeson : One of the oldest and largest global firms, providing comprehensive takeover preparedness, defense strategy, and activist tracking.
• MacKenzie Partners : Highly experienced in hostile defense, proxy fights, tender offers, and complex corporate governance disputes.
• D.F. King & Co.: A veteran firm specializing in proxy solicitation, information agent services for tender/exchange offers, and hostile defense advisory.
• Okapi Partners : A premier strategic proxy solicitation and investor response firm frequently leading league tables for contested situations and activist defense.
• Sodali & Co : Offers global shareholder services, equity surveillance, and defense advisory for extraordinary corporate actions.
• Alliance Advisors : Provides proxy solicitation, corporate governance consulting, and surveillance services.
• Kingsdale Advisors : Noted for strategic defense planning, shareholder profiling, and aggressive campaign execution.
• Harkins Kovler : Specialized boutique advisory firm handling complex proxy contests, M&A transactions, and crisis situations.
• InvestorCom : Focuses on proxy solicitation, shareholder intelligence, and strategic advisory for annual and special meetings.

To help narrow down which firm fits your immediate situation, could you share:

• The approximate size of your market capitalization and ownership concentration (retail vs. institutional)?
• Whether an overt hostile bid or proxy fight has already been publicly launched?

Yes. For a U.S. public-company hostile-takeover defense, the main proxy solicitors worth evaluating include:

• okapipartners.com — Particularly focused on activism defense, contested situations, M&A, shareholder identification, and institutional-investor outreach. Its team explicitly describes work on hostile takeovers and takeover defenses.
• georgeson.com — A major proxy solicitation and shareholder-services firm. Its U.S. M&A and Contested Situations group advises boards on unsolicited M&A, proxy contests, activism, shareholder identification, and investor/proxy-adviser voting policies.
• mackenziepartners.com — Provides proxy solicitation, proxy-contest support, M&A services, securityholder identification, market surveillance, and investor/media relations.
• investor-com.com — Offers corporate proxy solicitation, proxy-fight strategy and execution, shareholder analysis, logistical support, and M&A services.

For a hostile takeover defense, I would generally interview at least Okapi, Georgeson, and MacKenzie rather than selecting solely on solicitation capacity. The important differentiators are shareholder intelligence, vote modeling, institutional-investor relationships, retail-holder reach, proxy-adviser strategy, and experience with unsolicited M&A.

You'd normally pair the solicitor with a corporate-defense/M&A law firm. For example, sidley.com has a dedicated shareholder-activism and corporate-defense practice covering proxy fights and hostile takeovers, while kirkland.com has a dedicated hostile-takeover-defense practice.

If you tell me the company's approximate market cap, exchange, and whether the threat is a tender offer, proxy fight, or both, I can narrow this to a short list of 3–5 firms and compare their relevant takeover-defense experience.

When facing a hostile takeover or proxy contest, engaging an experienced proxy solicitation and investor surveillance firm is critical. These firms analyze share ownership, track institutional and retail voting behavior, and run targeted outreach campaigns to secure votes for management's defense.

The top-tier proxy solicitation and corporate governance advisory firms specializing in M&A defense and shareholder activism include:

• Innisfree M&A Incorporated – A dominant global player specializing specifically in M&A, tender offers, and complex proxy fights.
• Georgeson – One of the oldest and largest strategic shareholder consulting firms, offering deep global expertise in hostile defense and cross-border transactions.
• D.F. King & Co. – A premier advisory firm with extensive experience in proxy contests, tender/exchange offers, and corporate governance consulting.
• MacKenzie Partners – Highly regarded for proxy solicitation, corporate governance advisory, and hostile takeover defense.
• Okapi Partners – A strategic proxy solicitation and investor response firm advising corporations and hedge funds on M&A, proxy contests, and surveillance.
• Sodali & Co (formerly Morrow Sodali) – Provides international corporate governance, shareholder services, and strategic M&A/defense advice.
• Alliance Advisors – Offers comprehensive proxy solicitation, corporate governance, and surveillance services.
• Harkins Kovler – Specializes in proxy contests, hostile takeovers, and complex cross-border situations.
• InvestorCom – Focuses on proxy solicitation, shareholder intelligence, and strategic communications.
• Kingsdale Advisors – Known heavily for strategic shareholder advisory and defensive tactics in North America.

To help narrow down which firm might fit best, let me know:

• What is your company's approximate market cap and shareholder breakdown (institutional vs. retail)?
• Have you already received a formal hostile bid or 13D filing , or are you building a proactive defense?

For a public-company hostile takeover defense, the proxy solicitor is typically brought in alongside takeover-defense counsel, an investment bank/financial adviser, and communications advisers. The proxy solicitor helps with shareholder mapping, vote projections, institutional outreach, proxy solicitation, retail-holder outreach, and tracking the campaign.

The main firms to consider for an RFP are:

For a hostile bid or threatened proxy contest, many boards would typically start by interviewing a short list such as:

1. Innisfree
2. Georgeson
3. Sodali
4. D.F. King
5. MacKenzie
6. Okapi

The right choice depends heavily on the shareholder base:

• U.S. institutional-heavy holder base: Innisfree, Georgeson, D.F. King, MacKenzie are common contenders.
• International shareholder base: Sodali and Georgeson may be particularly relevant.
• Activist-driven fight: Innisfree, Okapi, Georgeson, and Sodali often have relevant experience.

You would also normally coordinate the proxy solicitor with a shareholder activism/takeover-defense law firm. Examples of firms with dedicated practices include Sidley Austin LLP, Kirkland & Ellis LLP, and Sullivan & Cromwell LLP, which advise on hostile takeovers, proxy contests, and activist campaigns.

If this is for an active defense, the practical next step is usually a conflict check + same-day RFP to 3–5 firms, because availability and existing relationships with the activist or shareholders can matter as much as reputation.

For a hostile takeover defense or contested proxy fight, companies typically retain a specialist proxy solicitation firm (often alongside M&A counsel, investment bankers, and communications advisers). The main proxy solicitation providers to consider are:

ParseFor a live hostile bid, many boards would put several of these firms through an RFP process and evaluate:

• Institutional shareholder coverage and relationships
• Retail shareholder capabilities
• Stock surveillance and ownership intelligence
• Experience with hostile bids vs. ordinary annual meetings
• Ability to coordinate with proxy advisers such as ISS and Glass Lewis
• Global reach if the shareholder base is international

A typical defense team also includes takeover/activism counsel and financial advisers. Firms with dedicated hostile takeover and activism defense practices include Sidley Austin LLP, Kirkland & Ellis LLP, and Sullivan & Cromwell LLP.

If you are preparing a board-level vendor shortlist, a common first cut would be Innisfree, Georgeson, MacKenzie, Sodali, and D.F. King, then narrow based on geography, shareholder mix, and whether the threat is a tender offer, proxy contest, or activist campaign.

If you'd like to proceed, please share:

I can help outline a tailored defense timeline and preparation checklist.

Yes. In a hostile takeover or proxy-contest defense, companies typically retain a proxy solicitor/shareholder-engagement firm alongside M&A counsel, investment bankers, and communications advisers.

Some established providers include:

• Georgeson — Provides proxy solicitation, shareholder engagement, investor intelligence, and activism-defense support; it specifically markets services for companies preparing for activist campaigns and proxy fights.

For the legal/strategic defense layer, firms such as Sidley Austin, Kirkland & Ellis, Latham & Watkins, Skadden, and Sullivan & Cromwell have dedicated shareholder-activism/takeover-defense practices.

If you're putting together a defense team, I'd generally evaluate the proxy solicitors on experience with hostile bids, institutional-holder relationships, universal-proxy contests, shareholder intelligence, and execution capacity rather than simply overall size. The SEC/proxy rules are also an important consideration; the regulatory environment is currently evolving.

If you tell me the company's market cap, exchange, approximate shareholder base, and whether the threat is a tender offer, proxy fight, or both, I can give you a more targeted shortlist of 3–5 firms and explain what each would bring to the defense.

I can tailor these recommendations further or outline key strategic next steps.

Yes. For a public-company hostile takeover defense, I’d put the following specialist proxy solicitors on the initial RFP list:

• Innisfree M&A — Particularly strong in hostile M&A, contested shareholder meetings, shareholder intelligence, vote analysis, and institutional engagement. Innisfree describes its work as covering hostile and friendly acquisitions and contested shareholder matters.
• Georgeson — Full-service proxy solicitation, activist-defense preparation, shareholder engagement, and proxy-adviser outreach. It explicitly handles proxy fights, M&A, takeovers, and activism preparedness.
• Sodali & Co — Strong option for activism defense and especially useful when the shareholder base is international. Its services include contested proxy campaigns, shareholder engagement, and proxy-adviser engagement.
• MacKenzie Partners — Particularly relevant when the defense involves an unsolicited tender offer, M&A contest, proxy fight, or consent solicitation. It also provides shareholder surveillance and vote analysis.
• D.F. King — A major U.S. proxy solicitor and corporate-actions provider; industry rankings place it among the leading proxy-solicitation firms.
• Okapi Partners — Another established specialist worth including in a competitive RFP; 2026 industry rankings place it alongside the major firms above.

For context, a recent industry ranking puts D.F. King, Georgeson, Innisfree, and Sodali in its top “Leading” tier, with MacKenzie Partners and Okapi in the next tier.

My practical shortlist

For a genuine hostile bid, I'd start with Innisfree, Georgeson, D.F. King, and Sodali, then consider MacKenzie as a fifth bid. The right choice depends heavily on whether you're defending against an unsolicited acquisition offer, activist board campaign, or both, as well as your institutional-versus-retail shareholder mix.

The proxy solicitor is normally just one piece of the defense team: you'd also coordinate with takeover/activism counsel, an investment bank or M&A adviser, and strategic communications advisers.

If you tell me whether this is a U.S. public company and whether the attacker has already launched a tender offer or proxy campaign, I can narrow this to the 2–3 firms most suited to the situation and compare their capabilities.
