Proxy Contest in M&A: Case Study of 2025–2026 Battles between Company A and Company B

In 2026, proxy contests in M&A are shaping up as a five-year high in deal-related activism, and settlements now dominate the playbook.

I’ve spent years watching how activists push for value, and the shift is clear: traditional proxy fights are down, settlements are up, and deal dynamics drive the activism map. In 2025, activist campaigns hit about 579 U.S. companies, a 3% dip from 2024, but the real story is how activists got outcomes. Settlements accounted for 89% of board seat gains, and votes won in shareholder meetings dropped about 20% from the prior year. That means activists aren’t chasing public fights as much as negotiated concessions or strategic divestitures. It’s cheaper, faster, and often more certainty-friendly for both sides.

From a deal context, 2025 was a banner year for M&A and a setup for 2026. U.S. transaction volume hit roughly $2.3 trillion, up 49% year over year, with buyers favored by capital markets and a regulatory environment that still rewards deal activity. When the market is hot, activism follows, because activists see leverage in deal rationales, governance tweaks, and strategic alternatives.

We’re seeing that in the 2026 landscape, where activists stay aggressive on value creation but prefer settlements over drag-out proxy fights. Withhold campaigns (targeted pressure tactic to block votes or decisions without full contests) and vote-no tactics expanded, giving activists lower-cost options to pressure boards without full-blown contests.

Let me map two clear strands you’ll see in 2026. First, the settlement-dominant path: 52 settlements in 2025 resulted in at least one board seat, up from 35 in 2024. Nearly half of those settlements occurred without public agitation, which tells companies they can avoid a spectacle and still satisfy activists. Second, the tactical evolution: with traditional contests shrinking, activists rely on withhold campaigns and targeted governance demands, aiming at specific changes like board refreshment, strategic reviews, or concessions around M&A timelines.

Real-world examples from 2025-26 illustrate the dynamics. In some high-profile moves, activists flagged targets like Kellanov, Kenvue, and Janus Henderson for potential divestitures or strategic redirection, and those names underscore how deal-focused activism translates into actual deal outcomes.

Honeywell’s corporate restructuring, following dialogue with Elliott Management, shows how activists influence capital-allocation decisions even when the company plans to stay intact. STAAR Surgical’s sale to Alcon faced organized opposition from Broadwood Capital, underscoring how hedge fund activism can challenge a deal’s value thesis and push for a more favorable outcome for shareholders.

Now, about the STAAR Surgical case

STAAR announced a sale to Alcon in 2025, a transaction activists scrutinized for value creation. Broadwood Capital, the largest investor, pressed for changes that would enhance deal value or alter the deal terms. The case demonstrates several key points I see repeating: activists can slow or reframe a deal by pushing for alternative financings, insisting on stricter termination fees, or demanding alternative bidders. The outcome in any given case hinges on the ability to secure concessions without losing deal certainty, and Broadwood’s push reflects how a dominant investor can shape the closing conditions and post-deal expectations. This is precisely why deal teams need to prepare a robust value thesis, a plan B bidder scenario, and a communication playbook that can handle a targeted activist letter before deal leverage erodes.

From a practitioner standpoint: three operational imperatives for 2026

From a practitioner standpoint, the 2026 proxy season will revolve around three operational imperatives. First, strengthen the deal thesis and diligence artifacts to withstand activist scrutiny. This means clear synergies, robust integration plans, and transparent capex/working capital assumptions; second, prepare for alternative routes, divestitures, spin-offs, or split structures, so you’re not surprised if an activist targets the deal’s optionality; third, plan investor engagement around 14a-8 changes and proxy advisory updates, since guidance from ISS and Glass Lewis will shape both engagement strategy and governance expectations. The MERCER and BDO perspectives show evolving proxy advisor rules and governance expectations that directly affect how you prepare for proxy season and respond to activist inquiries.

Practical steps for operating in 2026

In practical terms, here’s how to operate. Create a tactical playbook for deal-related activism that includes a settlement path, a no-fault alternative, and a communications plan to address investor concerns quickly. Build a governance package that anticipates withhold and vote-no pressures, including board refresh plans and clear criteria for evaluating strategic alternatives. Track the regulatory environment and 14a-8 developments so you’re not surprised by changes that affect engagement.

Data-backed takeaways and strategic outlook

Data-backed takeaways you’ll find valuable: 2025’s settlement dominance means you should assume a higher likelihood of negotiated outcomes in 2026 as activists seek efficient wins.

A five-year high in M&A activism means more potential deal pressure, but also more paths to a productive resolution if you deliver measurable value. In practice, the companies that succeed will be those with credible deal-at-scale value cases, responsive governance processes, and proactive investor outreach that demonstrates alignment with long-term strategic aims.

Logically, we must take into consideration th evolving mix of tactics. It doesn’t keep me up at night, but it does demand preparedness: withhold campaigns, targeted governance demands, and careful negotiation all sit in the same toolbox. The reality is that most activism in 2026 will advance through settlements rather than contested votes, and deal teams must be ready to negotiate or reframe value quickly.

In my opinion, the 2026 proxy season is less about fighting for a fight’s sake and more about shaping outcomes that unlock value, preserve deal certainty, and align with investor expectations. For readers focused on M&A terminology, this is a clear signal to study proxies, settlements, and deal-driven activism as a connected system.

Practical notes: monitor activist campaigns, prepare a robust deal thesis, align governance and board refresh plans with investor expectations, and anticipate withhold or vote-no scenarios.
