Pooled Employer Plans in M&A: How retirement strategy reduces risk

This momentum, however, comes with nuanced execution risks. Complex deals, compressed timelines, and growing expectations to realize value faster are all contributing to the demands placed on HR M&A teams. In this context, organizations that broaden their execution lens beyond traditional financing and synergies are better positioned to realize post-close value.

Why retirement plans are a hidden risk in M&A transactions

Retirement plans are often overlooked as a potential advantage in creating value for employees in transactions. Yet plan design, governance structure, and execution timelines can meaningfully affect both transaction costs, compliance risk, and workforce stability. Common long-term M&A challenges include:

• Fragmented plan structures following acquisitions of multiple entities
• Divergent governance and fiduciary structures across legacy plans
• Compressed timelines for blackout windows, payroll transitions and communications
• Unanticipated administrative burden and cost in employer-borne costs

The cumulative effect of these issues can erode hard-won operational synergies and distract leadership and HR teams from broader strategic priorities.

Getting the Total Rewards aspects of a deal right is a critical part of M&A planning, and a growing number of leaders recognize they must focus on retirement and benefits plan strategy. WTW research highlights the importance employees place on retirement benefits in how they value total rewards. Maintaining attractive retirement benefits during an M&A transaction is an easy way to sustain engagement levels during heightened periods of uncertainty. How retirement plans are addressed during deals can materially influence cost, execution risk, and employee experience.

Fortunately, there is a new tool available that offers a pragmatic, cost-effective approach to implementing defined contribution retirement solutions – Pooled Employer Plans (PEPs). A PEP is a retirement plan delivery model that allows employers to outsource most of their plan management responsibilities, including fiduciary oversight. In a PEP, a third-party Pooled Plan Provider assumes responsibility for key plan management and administration duties. This reduces the burden on individual employers and creates economies of scale.

Why Pooled Employer Plans (PEPs) are gaining momentum in M&A

Several trends expected to define deal activity in 2026 heighten retirement plan complexity:

• Carve-outs and divestitures: These deals often require rapid establishment of standalone retirement plans, complete with compliance, payroll and benefits governance readiness.
• Serial transactions and portfolio aggregations: As organizations pursue roll-ups or multiple acquisitions, the number of discrete retirement plans under a single corporate umbrella can multiply rapidly.
• Cross-jurisdictional and multi-entity integrations: Variations in plan design, eligibility and regulatory frameworks add layers of complexity.
• Speed-to-divestiture imperatives: Operational deadlines may leave limited runway to address retirement plan stand-up thoughtfully.

These dynamics call for early, integrated planning, treating retirement plans as intrinsic to the broader people agenda rather than a peripheral add-on.

Core advantages of PEPs in M&A

Pooled Employer Plans (PEPs) have emerged as one of several tools that organizations can use to streamline retirement plan strategy during complex deals. A PEP enables unrelated employers to participate in a single pooled defined contribution plan governed by a Pooled Plan Provider, offering potential advantages such as:

• Simplified governance and fiduciary structure: Centralizing certain administrative and fiduciary responsibilities with a Pooled Plan Provider can reduce internal operational burden.
• Scalability and consistency: PEPs can absorb multiple entities into a unified framework, facilitating plan consolidation where appropriate.
• Administrative relief: By reducing the number of discrete plans and associated vendor relationships, organizations can free HR and benefits teams to focus on strategic integration work rather than plan administration.

PEPs are especially valuable in divestitures and carve-outs for the following reasons:

• PEPs can help avoid unexpected higher participant fees. Employees being divested in a carve-out from a larger employer may lose access to the plan fees negotiated by the seller. A PEP capitalizes on scale to offer participant fees which may be more comparable to the seller’s plans.
• Typically there are fewer HR resources with benefits expertise in the perimeter of a carve-out. The ability to properly manage a new plan and its associated fiduciary obligations can prove challenging. With a pooled solution, however, the administrative burden and fiduciary risk and responsibility shifts to the PEP.

It is important to emphasize that PEPs are not a one-size-fits-all solution. Their applicability depends on deal specifics and compliance considerations. However, when properly aligned with broader integration objectives, PEPs can help mitigate complexity and cost leakage in deals.

Key questions for HR and M&A Leaders

As organizations prepare for M&A activity in 2026, early and deliberate retirement plan strategy discussions can strengthen integration outcomes. To determine whether a PEP should be part of your transaction strategy, consider:

• If we are looking at a divestiture or carve out, will NewCo have the resources, scale and purchasing power to effectively replicate the parent plan or should we look at a pooled solution?
• What administrative and fiduciary burdens will be introduced by standing up a new plan, and what internal capacity exists to manage them?
• Could a PEP accelerate go-live and reduce internal resource strain?

Addressing these questions early can surface potential areas of friction and enable a successful M&A transaction.

PEPs as a strategic tool in 2026 M&A
The 2026 M&A landscape presents compelling opportunities for strategic growth and portfolio transformation. As companies pursue these opportunities, expanding the scope of transaction planning to include retirement plan strategy can enhance operational readiness and workforce continuity. Tools like PEPs, when thoughtfully applied, offer a pragmatic mechanism to simplify complexity and support a smoother path from deal close to fully integrated enterprise.

Forward-looking leaders will benefit from treating retirement and benefits strategy as an essential component of their M&A playbook, enabling greater focus on value creation and sustained organizational performance.
