Fractional FD: PE Exit & Due Diligence Support

What does a fractional Finance Director with PE-backed exit experience deliver to a portfolio company approaching sale — and where does the PE exit context demand specific finance discipline that differs from general trade sale preparation?

PE-backed business exits are different from owner-managed business exits in specific ways that affect the finance work required. The buyer is sophisticated — typically a secondary PE house, a strategic acquirer with a corporate development function, or a public market route — and brings diligence resources well beyond what owner-managed transactions face. The hold period has been spent under sponsor governance, with monthly investor reporting that has accumulated a documentary trail the buyer will examine. Quality of Earnings analysis is mandatory rather than optional. The expectation that financial information is institutional-grade is absolute. And the timeline is driven by the sponsor’s fund cycle rather than by the seller’s personal preference, creating pace pressure that owner-managed exits don’t always face.

For PE-backed businesses approaching exit, fractional Finance Director engagement is increasingly the right model for the finance preparation work — particularly in mid-market portfolio companies (typically £10-50m EBITDA at the smaller end) where a permanent CFO already exists but the exit preparation work exceeds what the existing finance function can deliver alongside steady-state operations. The fractional FD provides dedicated transactional capacity for the 12-18 months before exit and through the process itself, complementing rather than replacing the permanent CFO.

This guide sets out what fractional FD engagement delivers in PE exit and due diligence contexts — Quality of Earnings preparation, vendor due diligence support, audit trail readiness for PE buyer scrutiny, technology due diligence specifically in PE deals, and the PE-specific commercial finance disciplines that distinguish portfolio company exits from general trade sales.

It is written from the perspective of FD Capital’s team — a specialist finance recruitment firm placing fractional FDs into UK PE-backed businesses approaching exit since 2018.

Why PE Exits Demand Specific Finance Preparation

PE-backed exits operate at a different intensity from owner-managed transactions, and the finance work required reflects that difference. Several specific characteristics distinguish PE exit preparation:

Sophisticated buyer diligence. Secondary PE buyers, strategic acquirers with mature corporate development functions, and public market participants bring substantial diligence resources. Quality of Earnings analysis, customer profitability deep-dives, working capital normalisation studies, debt-like item identification, and management presentation challenge are standard rather than exceptional. The seller’s finance function needs to produce information that survives this level of scrutiny.

Investor-grade reporting history. PE-backed businesses have produced monthly reporting throughout the hold period — Board packs, sponsor updates, KPI dashboards. The buyer will examine this historical trail for inconsistency, drift in metric definitions, deferred problems, and patterns that affect the forward forecast. Sellers whose monthly reporting has been inconsistent face uncomfortable diligence questions.

Sponsor exit timeline. The sponsor’s fund cycle drives the exit timeline. Sponsors typically need to return capital to LPs within specific windows, which means the exit happens when the sponsor decides — not when the management team feels ideally prepared. Finance preparation often runs against tighter timelines than owner-managed exits.

Sponsor governance through exit. The sponsor remains actively engaged through the exit process, with the exit committee or operating partner reviewing process decisions, financial information, and buyer engagement. The fractional FD coordinates closely with the sponsor’s exit team alongside management.

Existing CFO often retained. Most mid-market PE portfolio companies have a permanent CFO who will go through the exit process. Fractional FD engagement supplements rather than replaces — providing the additional transactional capacity needed for exit-specific work without expanding the permanent finance team during a defined period.

Multi-stage exit processes. PE exits often run as structured auctions with multiple rounds — teaser, info memo, first-round bids, management meetings, second-round bids, exclusive period, completion. Each stage has specific finance deliverables that the fractional FD coordinates.

Higher information standards across documents. The information memorandum, management presentation, vendor due diligence report, financial model, and data room content all need to align with each other and stand up to specialist scrutiny. Inconsistency between documents — different EBITDA add-backs in the IM versus the model, different growth assumptions in the management presentation versus the forecast — destroys credibility instantly.

Quality of Earnings: The Centrepiece of PE Exit Finance Work

Quality of Earnings (QoE) analysis is the core financial deliverable in PE exits. A QoE report produced by an independent accountancy firm — typically a Big 4, mid-tier or specialist QoE practice — provides the buyer with an analytically rigorous view of the business’s earnings, normalised for one-off items, accounting policy choices, and unusual events. Strong QoE work demonstrates the business’s earnings quality and supports the sponsor’s valuation argument; weak QoE work produces price chips during diligence or, in worse cases, breaks the deal.

The fractional FD’s role in QoE preparation is substantial:

Pre-QoE financial preparation. Before the QoE provider begins formal work, the financial record needs to be ready for analysis. Monthly management accounts cleanly reconciled to the statutory accounting record. Account-by-account substantiation files. Customer-by-customer revenue analysis with margin breakdown. Inventory analysis where applicable. Capex listing with categorisation. Working capital analysis with seasonal pattern identification. The fractional FD prepares this material before the QoE engagement begins, ensuring the QoE provider can do their work efficiently.

EBITDA add-back identification and substantiation. EBITDA add-backs — items that the seller argues should be excluded from EBITDA when calculating the multiple — are one of the most negotiation-intensive components of any PE exit. Common add-backs include one-off legal costs, restructuring expenses, non-recurring marketing investment, founder compensation differential to market rate, transaction-related costs. Each add-back needs documentary substantiation that the QoE provider can verify and the buyer can accept. The fractional FD identifies legitimate add-backs, prepares the substantiation, and avoids the over-claim that destroys credibility when challenged.

Revenue quality analysis. Revenue concentration, customer churn patterns, contract terms (renewal rates, contractual versus implied commitment, pricing trajectory over time), recurring versus one-off revenue split, gross versus net revenue presentation choices. The QoE provider will examine each of these dimensions. Strong fractional FD preparation surfaces issues before the QoE provider finds them and addresses them constructively.

Working capital normalisation. The working capital position at completion is a major commercial term in any PE exit. The QoE provider will calculate normalised working capital — typically the average of monthly closing working capital over the prior 12 months, adjusted for trend and seasonal pattern. The fractional FD ensures the working capital position is well-understood, that any anomalous months are explained, and that the seller’s normalisation argument is defensible.

Debt-like items identification. Items that should be treated as debt rather than working capital — accrued bonuses, deferred revenue, customer deposits, environmental provisions, lease obligations, pension deficit, regulatory provisions, dividend declarations. The buyer will argue many items are debt-like; the seller wants to limit this to genuine debt-like items. The fractional FD prepares the seller’s position and supports it through negotiation.

Forecast support. The QoE engagement typically extends to commentary on forecast assumptions and historical actual versus prior forecast accuracy. Strong forecast preparation includes documentation of underlying drivers, sensitivity analysis, and historical accuracy demonstration. The fractional FD ensures the forecast stands up to QoE-level scrutiny.

QoE report management. The QoE report itself goes through draft cycles. Strong fractional FDs review drafts carefully, push back on findings that are inaccurate or overstated, ensure the seller’s perspective is represented fairly, and resolve open issues before the report is finalised. Weak management of the QoE drafting process produces final reports that disadvantage the seller in subsequent buyer negotiation.

Vendor Due Diligence Coordination

Vendor Due Diligence (VDD) — sometimes called sell-side diligence — is the comprehensive due diligence package commissioned by the seller (or sponsor) before buyers engage. A typical VDD pack includes financial VDD (often combined with QoE), commercial VDD (market and competitive analysis), legal VDD, tax VDD, and technology VDD where the business is technology-intensive. Buyers rely on the VDD output for a substantial portion of their diligence, with their own work focused on validation and specific incremental questions rather than full coverage.

The fractional FD coordinates the VDD process across workstreams:

Provider selection. Each VDD workstream typically uses a different provider. The fractional FD recommends provider selection based on prior experience — which Big 4 financial advisory teams produce strong work in this sector, which commercial DD boutiques have credibility with PE buyers, which tax firms have relevant capability for the business’s structure. Sponsor preference often guides selection but the fractional FD’s input shapes the discussion.

Information provision. Each VDD provider needs extensive information from the business. The fractional FD coordinates the information requests, manages the supply rhythm, and ensures consistency across workstreams. The same financial data must reconcile to the same numbers in the financial VDD, the commercial VDD’s revenue analysis, and the tax VDD’s profit allocation work.

Cross-workstream consistency. A common VDD failure mode is inconsistency across workstreams — the financial VDD characterises the business one way, the commercial VDD differently, and the buyer notices. The fractional FD reviews drafts across workstreams and ensures the integrated picture is coherent.

Issue identification and resolution. VDD provides the seller with an independent view of issues that buyers will see. Issues identified in VDD can often be resolved or mitigated before buyers engage. The fractional FD ensures issues identified are addressed rather than buried — addressed issues become part of the narrative; buried issues become diligence ambushes.

Final report quality. VDD reports are referenced by buyers throughout the process. The fractional FD ensures final reports present the business credibly, address potential buyer concerns proactively, and provide the analytical content that supports the seller’s valuation argument.

For wider VDD context see our Vendor Due Diligence Guide.

Audit Trail Readiness for PE Buyer Scrutiny

PE-backed businesses have produced years of monthly management accounts, Board packs, and sponsor reporting. PE buyers examine this historical trail for evidence of how the business has actually performed against plan, how management has communicated about issues, and what patterns emerge that affect forward expectations.

The fractional FD ensures the audit trail is genuinely ready for buyer scrutiny:

Reporting consistency over time. KPI definitions that have remained stable across the hold period demonstrate disciplined reporting. KPIs that have been redefined, regrouped, or quietly changed when underlying performance shifted produce uncomfortable buyer questions. The fractional FD reviews historical reporting for consistency and prepares explanations for any changes that exist.

Management commentary review. Monthly Board packs typically include management commentary. Buyers read this commentary to understand how management has thought about the business through the hold period. Optimistic commentary that didn’t match subsequent performance, or commentary that played down emerging issues, becomes evidence of management credibility risk. The fractional FD reviews historical commentary and prepares responses to anticipated buyer questions.

Forecast versus actual track record. Buyers examine how accurate the business’s forecasts have historically been. Significant or repeated forecast misses — particularly to the downside — affect forecast credibility going forward. The fractional FD prepares the forecast accuracy analysis honestly, with explanations for material variances and demonstration of how forecasting discipline has improved.

Customer and revenue data integrity. Customer counts, revenue by customer, churn rates, retention curves — these need to reconcile across different reports and time periods. Inconsistency between the customer count in last quarter’s Board pack and this quarter’s data room file creates diligence problems. The fractional FD reconciles historical customer and revenue data and addresses inconsistencies.

Acquisition integration history. If the business has made acquisitions during the hold period, the integration outcomes are relevant to PE buyers — both for the value the integrations created and as evidence of management acquisition capability. The fractional FD prepares the acquisition track record honestly, with synergy realisation analysis and explanation of any deviations from original deal thesis.

Financial control environment. The strength of internal controls during the hold period matters for the buyer’s confidence in the financial information they are buying. The fractional FD ensures the control environment is documented, that any control weaknesses identified during the hold period have been addressed, and that the buyer’s diligence can verify control effectiveness.

Technology Due Diligence in PE Deals

Technology due diligence has become a substantial component of PE deals across most sectors, not just technology businesses. Software-enabled services, healthcare with health-tech components, financial services with fintech elements, retail with ecommerce technology, manufacturing with industrial technology — each face technology DD that examines the business’s technology stack, IP position, technical debt, cybersecurity posture, scalability, and team capability.

The fractional FD coordinates the financial dimensions of technology DD:

Technology cost categorisation. Software development costs (capitalised versus expensed), infrastructure costs, third-party software licences, technical contractor costs, IT operations costs. Buyers want to understand what the business actually spends on technology, how that spend has scaled, and what proportion is investment in capability versus run-rate cost. The fractional FD prepares this analysis with clear categorisation that survives buyer scrutiny.

R&D capitalisation policy. Software development costs that have been capitalised under IFRS 38 (or FRS 102 Section 18) are visible on the balance sheet. The capitalisation policy, the basis for capitalisation, and the amortisation profile all matter to buyers. The fractional FD ensures the policy is defensible, applied consistently, and clearly documented.

Technology vendor concentration. Critical dependencies on specific cloud providers, SaaS tools, or technology partners affect the business’s risk profile. Buyers want visibility into vendor concentration and contractual protections. The fractional FD prepares the vendor analysis with contract terms summary.

Capex requirements forward. Technology businesses often require ongoing capex investment in infrastructure, platform development, and capability expansion. Buyers want to understand whether forecast capex is realistic given the business’s growth trajectory. The fractional FD prepares the capex forecast with technical input from the engineering leadership.

IP ownership and licensing. Buyers want clean IP ownership, with no contractor IP gaps, no unclear licensing arrangements, no open-source compliance issues. The fractional FD coordinates with the legal team on IP DD preparation, ensuring the IP register and contractual position is clean before buyers engage.

Cybersecurity posture. Cybersecurity DD has become standard in PE deals. Buyers commission specialist cybersecurity assessments and require evidence of security practices, incident history, and ongoing investment. The fractional FD prepares the financial dimensions — security spend trajectory, incident remediation costs, ongoing security investment plan.

Technology team analysis. Engineering team size, capability, retention, geographic distribution, contractor versus employee mix. PE buyers see the technology team as a major part of what they are acquiring. The fractional FD prepares the team analysis alongside the engineering leadership.

Deal Structure Negotiation in PE Exits

PE exit deal structure has specific characteristics that the fractional FD engages with alongside the corporate finance advisor and legal team. Specific points where finance input shapes commercial outcome include:

Locked-box versus completion accounts. PE-backed exits more frequently use locked-box mechanism (price fixed at a reference balance sheet date with no completion accounts adjustment) than owner-managed deals. The reference balance sheet date and the contractual leakage definition need careful attention. The fractional FD ensures the reference date is favourable and the leakage definition is properly drafted. See our Locked Box and Completion Accounts Guide.

Working capital peg. Where completion accounts are used, the working capital peg negotiation is critical. The fractional FD prepares the seller’s working capital analysis, identifies the normalised level the seller will defend, and supports negotiation against the buyer’s typically different view.

Debt-like items definition. The list of items deducted from enterprise value to derive equity value — debt, debt-like items, target working capital adjustment — has material price implications. The fractional FD prepares the seller’s position with documentary support for each item.

Cash-free, debt-free framework. Most PE exits structure pricing on a cash-free, debt-free basis with working capital peg. The mechanics of how cash and debt are defined, dated, and adjusted at completion need careful handling. The fractional FD ensures the SPA mechanics produce the commercial outcome the seller intended.

Warranty and indemnity scope. The W&I insurance market in UK PE exits is well-developed. The W&I insurer typically requires specific warranty drafting, disclosure standards, and indemnity scope. The fractional FD coordinates with the W&I broker, the legal team, and the buyer’s insurance position. See our W&I Insurance Guide.

Management equity rollover. Where management is rolling over equity into the new structure (typical in secondary PE exits and many strategic acquisitions), the rollover terms — valuation basis, ratchet mechanics, vesting, leaver provisions — affect management’s economic outcome materially. The fractional FD models the rollover economics and supports management’s negotiation alongside their legal advisor.

Earn-out where used. PE exits to strategic buyers sometimes include earn-out components. The fractional FD’s role in earn-out structuring is similar to the M&A context generally but with PE-specific considerations around the rolling management’s involvement during the earn-out period. See our Earn-Out Guide.

The Fractional FD as Bridge Between CFO and Sponsor

One of the underappreciated values of fractional FD engagement in PE exits is the bridging role between the permanent CFO (focused on running the business through the exit period) and the sponsor (focused on maximising exit outcome). The fractional FD provides dedicated transactional capacity that supports both:

For the permanent CFO: the fractional FD takes on much of the exit-specific workstream — VDD coordination, data room preparation, diligence response, deal mechanics — that would otherwise consume the CFO’s time and pull them away from running the business. The CFO retains overall finance leadership but is freed to focus on operational performance through the exit period.

For the sponsor: the fractional FD provides additional senior finance capacity dedicated to the exit, with prior PE exit experience that the sponsor can rely on. The sponsor’s exit committee or operating partner has a direct working relationship with the fractional FD on transaction matters without expanding their direct demands on the CFO.

For management: the fractional FD often becomes the trusted neutral party who can represent management interests in negotiation while maintaining sponsor confidence. This is particularly valuable in management equity rollover negotiations where management and sponsor interests don’t fully align.

The bridging role works because the fractional FD has the seniority to engage substantively with all parties, the focused mandate to dedicate time to the exit, and the independence (as a fractional engagement rather than permanent staff) to navigate any tension that arises during the process.

Post-Exit Considerations for Management

For PE-backed business management teams who roll over equity into the new structure or who continue with the buyer post-deal, post-exit considerations matter. The fractional FD often supports these alongside the exit work:

New structure economics. Management rolling over into a secondary PE structure has new equity economics to understand — preference stack, ratchet mechanics, vesting, leaver provisions. The fractional FD models the personal financial outcomes for senior management across plausible exit scenarios at the next event.

Tax structuring. Personal tax outcomes from PE exits are complex — Business Asset Disposal Relief application (10% on qualifying gains up to £1 million per individual lifetime allowance, with main rate CGT applying above this threshold), share-for-share rollover treatment, deferred consideration tax treatment, employee shareholder status implications. The fractional FD coordinates with personal tax advisors to ensure management understand and optimise their personal positions.

Earn-out monitoring. Where earn-outs apply, ongoing monitoring through the earn-out period protects management’s economic outcome. The fractional FD often continues engagement at reduced intensity through the earn-out period to support metric tracking and any disputes.

Reporting transition. Management staying with the new owner faces a transition in reporting expectations — from the previous sponsor’s expectations to the new owner’s, which may be quite different. The fractional FD supports management through this transition.

Career conversation. Senior managers staying through the next hold period need clarity on their roles, equity participation, and decision-making authority under the new owner. The fractional FD often supports management’s career conversations alongside the deal mechanics.
