The Proxy Solicitation Industry: Who Controls the Vote

When a shareholder vote matters — whether it is a routine annual meeting, a merger approval, or a contested board election — corporations and activist investors alike turn to proxy solicitation firms. These specialized advisors orchestrate the logistics, strategy, and outreach required to secure favorable voting outcomes from dispersed shareholder bases.

Market Structure

The proxy solicitation industry is a concentrated, relationship-driven market. A handful of established firms — Innisfree M&A, Sodali & Co, Georgeson, MacKenzie Partners, D.F. King, and Okapi Partners — handle the majority of high-profile engagements in the United States. In Canada, Kingsdale Advisors and Laurel Hill dominate. Globally, Sodali & Co operates the widest network with offices across North America, Europe, and Asia-Pacific.

When Proxy Solicitors Are Engaged

Routine Annual Meetings
Ensuring quorum and favorable votes on director elections, say-on-pay, and auditor ratification. Larger firms like Georgeson and D.F. King handle thousands of these each season.
Contested Elections & Activist Campaigns
The highest-stakes engagements. Both the issuer and the dissident typically retain competing solicitors. Innisfree M&A and Okapi Partners are frequently retained in proxy fights.
M&A Transactions
Merger votes, tender offers, and schemes of arrangement require shareholder approval thresholds that solicitors help achieve through targeted outreach.
Governance Proposals
Shareholder proposals on ESG, executive compensation, and board declassification increasingly require proactive solicitation strategies.

Proxy Advisory vs. Proxy Solicitation

These are distinct roles often confused. Proxy advisory firms (ISS, Glass Lewis) advise institutional investors on how to vote. Proxy solicitation firms work for issuers or activists to get votes cast in their favor. The two interact constantly — solicitors often strategize around anticipated ISS and Glass Lewis recommendations.
