Private Equity Post Merger Integration Services
Integration Services That Move at the Speed of a Deal
Private equity firms don't have the luxury of time. From the moment a deal closes, the clock is ticking on the value creation thesis. Every day of integration delay is a day of unrealized synergies, management distraction, and execution risk.
Stonehill provides post merger integration services built for the pace and accountability of private equity. We bring the structure, the team, and the execution horsepower to move fast without sacrificing the quality of the integration.
Integration Services Designed Around the PE Value Creation Model
Every service Stonehill provides is mapped to what actually drives value in a PE-backed company: EBITDA expansion, synergy realization, talent retention, and operational scalability. We don't run generic integration playbooks — we build our approach around your deal thesis.
“Stonehill’s integration services are not advisory-only. We embed our team inside the portfolio company and lead execution from the inside — accountable to the same milestones as the sponsor.”
Our Core PE Integration Services
Integration Management Office (IMO) Leadership
We establish and run the IMO from Day 1 through completion. This includes building the master integration workplan, running cross-functional steering meetings, tracking milestones and owners, managing risks, and reporting to the PE sponsor on integration progress. The IMO is the operational nerve center of the integration, and Stonehill leads it.
Pre-Close Integration Planning
The 30–60 days before close are the most valuable preparation time you have. Stonehill uses this window to build the full integration strategy, identify workstream owners, prepare Day 1 communications, and complete pre-close tasks that cannot wait until after signing. Sponsors who invest in pre-close planning consistently execute faster integrations.
Day 1 Readiness Program
Day 1 has one job: don't break anything. Stonehill manages every element of Day 1 readiness — employee communications, leadership announcements, system access, IT transition, customer-facing messaging, and operational continuity protocols. We run Day 1 tabletop exercises in advance so every stakeholder knows exactly what to expect.
Synergy Identification & Realization Tracking
We work with the PE sponsor and portfolio management team to identify, size, and sequence synergy opportunities — both cost and revenue. We then build the tracking infrastructure to measure realization against deal model assumptions and provide regular reporting to the board and operating partners.
Operating Model Design
Post-merger, two organizations need to become one. Stonehill leads the operating model design process — defining the organizational structure, reporting relationships, decision rights, and governance frameworks that will govern the combined entity. We facilitate alignment between the management team and PE sponsor on the target operating model before execution begins.
People, HR & Change Management
People risk is the most underestimated element of integration. Stonehill leads organizational design, role mapping, retention planning, and change management communications. We reduce attrition of key talent by providing structure, clarity, and consistent communication throughout the integration process.
Technology & Systems Integration
Technology integration is often the longest lead-time workstream. Stonehill assesses the combined technology landscape, recommends a consolidation or integration path, and manages execution across ERP, CRM, HRIS, and IT infrastructure workstreams. We manage vendor relationships and escalate issues before they become migration blockers.
Customer & Commercial Integration
Revenue is at risk during every integration. Stonehill develops customer communication strategies, manages sales force alignment, and protects customer relationships during the transition. We ensure that the commercial organization continues to perform while the back office integrates.
Engagement Models
Full IMO Leadership
Stonehill provides a dedicated integration team that embeds inside the portfolio company and leads the entire integration from Day 1 through completion. Best suited for complex or high-priority integrations where the management team needs full integration leadership support.
Functional Workstream Support
Stonehill provides targeted expertise in one or more specific workstreams — technology, people, operations, or commercial — while the internal team or another partner leads the overall integration. Best suited for integrations where the management team has bandwidth but lacks functional expertise in specific areas.
Integration Advisory & Coaching
Stonehill provides strategic guidance, frameworks, and coaching to an internal integration team. We review workplans, identify risks, facilitate key decisions, and provide accountability — without embedding a full team. Best suited for PE sponsors with experienced operating partner resources who want expert oversight.
Reporting & Governance for PE Sponsors
Stonehill is built to give PE sponsors the visibility they need without creating reporting overhead. We provide:
• Weekly status reports against the master integration workplan
• Risk and escalation logs with recommended actions
• Synergy realization tracking vs. deal model assumptions
• Monthly board-ready integration update decks
• Direct access to the Stonehill engagement lead at any time
