Deal Pricing Support: Find CFOs Who Have Structured and Managed Earn-Outs Before
Earn-outs and deferred consideration are the mechanisms by which UK M&A deals bridge the gap between what a seller wants for a business and what a buyer is willing to pay at completion. Rather than the buyer paying the entire purchase price in cash on day one, a portion is paid later — either on a fixed timetable (deferred consideration) or conditional on the business hitting agreed performance targets (earn-out). For sellers, these mechanisms can unlock the difference between a deal completing and a deal collapsing, and can add meaningful value if the business delivers on the forecasts that supported the deal. For buyers, they manage risk on the forecast period and retain capital discipline by linking price to demonstrated performance rather than management’s projections. Both are near-universal features of the UK mid-market M&A landscape and every business owner approaching a sale needs to understand how they work.
This guide covers earn-outs and deferred consideration for UK management teams, business owners, finance leaders and advisors involved in or approaching transactions. It sets out what earn-outs are, how they are structured in practice, the metrics typically used to trigger payment, the tax treatment for UK sellers, the parallel mechanics of non-contingent deferred consideration and vendor loan notes, how earn-outs interact with the wider deal pricing framework (locked box, completion accounts, escrow), the common disputes that arise during the earn-out period, and the finance leader’s role in structuring and managing this work.
Earn-outs in particular are one of the most commercially consequential and legally complex elements of a UK M&A deal. They are easy to structure badly, and structural errors made at SPA stage often surface as disputes 18-24 months later when real money is at stake. The technical detail in this guide is deliberately substantive — not every seller or buyer needs to read it all, but anyone signing an SPA with earn-out provisions should understand what they are agreeing to and what the common pitfalls look like.
This guide is part of FD Capital’s broader Knowledge Centre series and sits alongside our guides on preparing for private equity, management buyouts, financial due diligence and M&A due diligence.
What an Earn-Out Is and Why Earn-Outs Exist
An earn-out is a contractual mechanism within the sale and purchase agreement (SPA) under which part of the consideration for the business is paid to the seller after completion, conditional on the business achieving specified performance targets during an earn-out period. The payment may be a single sum at the end of the period, staged payments tied to interim milestones, or a formulaic calculation based on the actual performance delivered.
Why earn-outs exist — the commercial rationale
Earn-outs solve three specific commercial problems that recur in UK transactions:
- Valuation gap: the seller values the business based on optimistic forecasts, the buyer values it based on conservative assumptions, and neither will move. The earn-out bridges the gap — the buyer pays less if forecasts are not met, more if they are.
- Forecast risk transfer: when a significant portion of the valuation depends on future growth that has not yet been demonstrated, the buyer reasonably wants the seller to carry some of the execution risk. The earn-out keeps the seller economically incentivised to deliver the forecast.
- Key-person retention: where the seller is an individual (typically a founder) whose continued involvement drives value in the business, the earn-out keeps them engaged for a transition period rather than allowing immediate disengagement after completion.
When earn-outs are and aren’t appropriate
Earn-outs work best when the business is genuinely growing, the seller remains involved in driving that growth, and the performance targets are within the seller’s influence. They work less well when the seller is exiting completely and has no further influence, when the target business will be operationally integrated into a larger acquirer (losing its standalone identity), or when the growth is driven by external factors outside management control.
Prevalence in UK transactions
Earn-outs appear in a substantial proportion of UK mid-market M&A deals, particularly in founder-led business sales and in technology or professional services transactions where a significant part of the value is tied to ongoing key-person involvement. Earn-outs are less common in PE-backed secondary sales (where management typically rolls equity forward instead) and in large-cap transactions (where the scale of the business makes earn-outs operationally impractical). See our M&A Due Diligence guide for the broader UK transaction context.
Earn-Out Structures and Metrics
Earn-out structures vary considerably across UK deals but a set of standard patterns has emerged. Understanding these patterns helps sellers negotiate better terms and helps buyers design structures that actually deliver the risk transfer they intend.
Earn-out metrics — what triggers payment
The trigger for earn-out payment is some performance measure of the target business during the earn-out period. The most common UK earn-out metrics are:
- EBITDA: the most common earn-out metric in UK deals. Aligns with how the original valuation was calculated (typically an EBITDA multiple), and captures both revenue performance and margin discipline. Creates risk that the seller focuses on short-term EBITDA optimisation at the expense of long-term investment.
- Revenue: simpler to measure, less open to accounting interpretation, but does not capture profitability. Used where the commercial thesis is revenue-led (e.g. scaling a SaaS business to an ARR target).
- Gross profit: sits between revenue and EBITDA. Used where the buyer wants to incentivise sales and margin discipline but not operational cost management.
- Specific commercial milestones: customer acquisition targets, contract wins, product launches, regulatory approvals. Used particularly in technology transactions where specific commercial events transform the value of the business.
- Retention metrics: customer retention, key-person retention, repeat business percentages. Used in businesses where relationship continuity is the primary value driver.
- Combined or “tiered” metrics: earn-out payments conditional on multiple triggers, with different payments for different levels of performance.
The choice of metric has significant implications for behaviour during the earn-out period and for the likelihood of disputes. EBITDA-based earn-outs are the most common source of disputes because EBITDA is subject to multiple accounting judgements that can materially affect the calculation.
Earn-out calculation formulas
The formula converting performance into payment varies by deal:
- Multiple of achieved performance: e.g. earn-out payment equals 5x the excess EBITDA above a threshold. Creates leverage but can produce large swings in payment for small changes in performance.
- Sliding scale: defined payment amounts at defined performance thresholds, with interpolation between them. Smoother outcomes but more complex to document.
- All-or-nothing: full payment if threshold hit, zero otherwise. Used rarely because of the cliff-edge dynamics it creates.
- Cumulative with claw-back: multi-year structures where payments in later years depend on maintaining prior-year performance. Complex but useful for businesses with volatile earnings.
Earn-out ceilings and floors
Most UK earn-outs include maximum payment ceilings (“caps”) to limit the buyer’s total exposure if performance substantially exceeds the forecast, and sometimes minimum payment floors (“collars”) to give sellers some protection in adverse scenarios. Caps are near-universal; floors are contentious and often negotiated out.
The Earn-Out Period
The earn-out period is the timeframe during which the target business’s performance is measured for earn-out purposes. The length and structure of this period materially affects deal economics for both parties.
Typical earn-out periods
UK earn-out periods most commonly run 1-3 years from completion. Shorter periods (1 year) provide faster resolution and lower risk of operational drift from the original business plan, but capture less of the growth trajectory. Longer periods (3+ years) capture more value but increase the risk of disputes, operational changes that distort measurement, and strategic divergence between buyer and seller. Two-year earn-outs have become the most common default in UK mid-market transactions.
Staged versus terminal payments
Earn-out structures pay either:
- At the end of the period only: a single payment based on cumulative performance across the earn-out period. Simpler, but back-loads the seller’s incentive.
- In annual tranches: payments at the end of each earn-out year based on that year’s performance. More balanced incentives, but creates complexity where underperformance in year 1 might be recoverable in year 2.
Seller engagement during the period
The SPA typically sets out the seller’s role during the earn-out period — continued executive or advisory position, minimum time commitment, performance expectations, and the circumstances in which the relationship can be terminated. Where the seller is terminated early, earn-out provisions usually include “good leaver” and “bad leaver” mechanisms analogous to those in management equity structures. See our Sweet Equity guide for how these leaver provisions work in the equity context.
Deferred Consideration (Non-Contingent)
Deferred consideration is conceptually simpler than earn-out but closely related. Where an earn-out is contingent on performance, deferred consideration is fixed in amount but simply paid later. Both represent payments falling due after completion; they differ on whether payment is certain or conditional.
Why deferred consideration is used
Buyers use deferred consideration to manage cash flow (spreading the purchase price over multiple years rather than requiring full cash at completion), to provide tax efficiency (in certain structures), to maintain leverage capacity (reducing the debt required at completion), or simply because the seller agrees to the staged payment as part of the overall deal structure. Sellers accept deferred consideration typically because the alternative is a lower headline deal price or because the deferred payment carries interest that makes the economics attractive.
Typical deferred consideration structures
- Fixed-schedule payments: specified sums payable on defined dates (commonly 12, 24, and 36 months post-completion). Interest may or may not apply.
- Deferred consideration loan notes: the deferred sum is documented as a loan note issued by the buyer to the seller, with interest terms and maturity date. Creates clearer documentation than a contractual deferred payment.
- Inflation-linked deferred consideration: deferred sums uplifted by an index (typically RPI or CPI) to preserve value over the deferral period.
Security for deferred payments
Deferred consideration creates credit risk for the seller — the buyer might not pay when the time comes. Sellers typically require one of the following forms of security:
- Escrow account: the deferred amount held by an escrow agent and released on the agreed date, protecting the seller against buyer insolvency
- Bank guarantee: a bank’s commitment to pay the deferred amount if the buyer defaults
- Parent company guarantee: where the buyer is a subsidiary, the parent company formally guarantees payment
- Security over business assets: charges granted over the target business’s assets to secure payment
Security is typically not granted for the full amount — sellers often accept unsecured buyer covenants for part of the deferred consideration in exchange for better overall deal economics.
Vendor Loan Notes
Vendor loan notes are a specific form of deferred consideration documented as a loan instrument from the buyer to the seller. They are particularly common in UK MBO structures where they help bridge the financing gap between what senior debt and equity providers will fund and what the vendor wants at completion.
How vendor loan notes work
Instead of cash at completion, the seller accepts a loan note from the buyer (or from an acquisition vehicle) with specified interest rate, maturity date, and repayment terms. The loan note sits in the capital structure subordinated to senior debt and usually to mezzanine, so the seller ranks behind the banks in the payment waterfall.
Vendor loan notes in MBOs specifically
In UK MBOs, vendor loan notes typically represent 5-15% of the enterprise value. They allow the transaction to complete at a price higher than senior debt and equity alone could support, by giving the vendor a deferred receivable in return for a portion of the consideration. The vendor effectively provides junior capital to the acquisition. See our Management Buyouts guide for how vendor loan notes fit into the wider MBO capital structure alongside senior debt, mezzanine finance, and equity.
Interest and maturity
Vendor loan note interest is typically set at a rate that balances providing a return to the vendor with keeping the cost manageable for the acquisition vehicle. UK practice has historically used rates in the 5-10% range depending on market conditions and subordination. Maturity is typically 5-7 years, aligning with the sponsor’s intended hold period and exit timing.
Repayment mechanics
Some vendor loan notes are interest-only during the term with a bullet repayment at maturity; others amortise over the term. Most include mandatory repayment triggers on an exit event (sale, IPO, refinancing), allowing the vendor to be paid out when the sponsor realises their investment.
Contingent Consideration — The Accounting Perspective
“Contingent consideration” is the accounting term for any purchase price element that is not fixed at completion — earn-outs being the principal example. The accounting treatment affects how the acquirer recognises the transaction under UK GAAP (FRS 102) or IFRS, and how changes in the expected payment are reflected in the acquirer’s subsequent financial statements.
Initial recognition
Under UK GAAP (FRS 102) and IFRS (IFRS 3), contingent consideration is recognised at fair value at the acquisition date as part of the purchase consideration. Fair value is management’s best estimate of what will actually be paid, based on the probability-weighted range of possible outcomes.
Subsequent changes
If the actual outcome differs from the initial estimate, the treatment depends on whether the contingent consideration is classified as equity (rare) or as a liability (most cases):
- Liability classification: re-measured at fair value at each reporting date, with changes recognised in the P&L. This creates volatility in the acquirer’s reported earnings during the earn-out period.
- Equity classification: not subsequently re-measured. Reserved for specific structures where the consideration is settled in a fixed number of the acquirer’s equity shares.
Implications for buyer reporting
Earn-outs can create material P&L volatility for buyers in the years following acquisition. This is particularly visible in PE-backed buyers reporting to sponsors on monthly results, where a change in earn-out accrual can significantly affect reported EBITDA. Finance leaders on the buyer side need to anticipate and communicate this dynamic to avoid surprising stakeholders.
Deal Pricing Context — How Earn-Outs Fit with Other Mechanisms
Earn-outs and deferred consideration are elements of a wider deal pricing framework that also includes locked box or completion accounts, working capital adjustments, escrow arrangements, and warranty and indemnity (W&I) insurance. Understanding how these elements fit together is essential for structuring or evaluating a deal.
Locked box versus completion accounts
The fundamental pricing decision in any deal is whether to use a locked box or completion accounts mechanism:
- Locked box: the purchase price is calculated based on an audited or near-audited balance sheet at a pre-completion date (the “locked box date”). Risk of business performance between the locked box date and completion sits with the buyer (typically compensated by an interest charge on the locked box price). Widely used in UK PE deals for process speed and certainty.
- Completion accounts: the purchase price is adjusted after completion based on a completion-date balance sheet. Typically involves post-completion true-up of working capital, net debt, and sometimes other items. More accurate but slower and more disputed.
Earn-outs operate independently of whether locked box or completion accounts is used — they sit as a separate element of the purchase consideration payable after completion based on future performance.
Working capital adjustment
Nearly all UK deals include some form of working capital adjustment ensuring the buyer inherits a “normalised” working capital level. The target working capital is typically established during financial due diligence (see our FDD guide) and the actual working capital at completion (or locked box date) is reconciled against this target. Any shortfall reduces the purchase price; any excess increases it.
Escrow and holdback
In addition to earn-out and deferred consideration, deals may include:
- Escrow account: a portion of the completion consideration held by an independent agent for a defined period, providing a pool from which the buyer can recover against warranty claims. Typically 5-15% of consideration held for 12-24 months.
- Holdback: similar concept where the buyer retains a portion of the purchase price to cover specific identified risks (e.g. disputed tax positions). Released on defined conditions.
W&I insurance
Warranty and indemnity insurance — increasingly standard in UK PE deals — shifts warranty risk from the seller to an insurance provider in exchange for a premium. W&I does not replace earn-outs, which cover performance risk rather than warranty risk, but reduces the seller’s post-completion exposure in parallel.
The full deal pricing stack
A typical UK mid-market deal therefore involves multiple pricing elements working together: enterprise value at locked box or completion; working capital adjustment; net debt adjustment; escrow retained against warranty claims; earn-out contingent on future performance; deferred consideration at fixed dates; vendor loan notes in MBO structures. The CFO and the corporate finance advisor work together to balance these elements so the overall structure achieves the commercial intent without creating operational complexity that destroys value post-completion.
Tax Treatment of Earn-Outs and Deferred Consideration for UK Sellers
The tax position of earn-outs and deferred consideration is one of the most important technical issues in any UK transaction. The treatment affects the seller’s net proceeds materially and changes the economics of the deal structure. This section provides a general overview only — all sellers should obtain specialist tax advice from a transaction-experienced advisor before signing an SPA.
General principles
For an individual UK seller disposing of shares in a trading company:
- Disposal is typically subject to capital gains tax (CGT)
- Business Asset Disposal Relief (BADR) may reduce the CGT rate on qualifying disposals — see our BADR guide for full detail including the lifetime allowance and qualifying conditions
- Earn-out and deferred consideration proceeds are included in the overall disposal consideration but the timing of when they are brought into charge to tax depends on the structure
Earn-out specifically — ascertainable versus unascertainable
HMRC distinguishes between “ascertainable” earn-outs (where the maximum amount is fixed at completion, e.g. a specified cap) and “unascertainable” earn-outs (where the amount is genuinely open-ended). The tax treatment differs:
- Ascertainable earn-outs: typically included in the disposal consideration at completion at the fair value of the right to receive, with subsequent differences from actual receipts treated separately.
- Unascertainable earn-outs: the “Marren v Ingles” position applies — the right to receive is a separate chargeable asset at completion, valued at its then fair value, with gains or losses on the actual receipt compared with this valuation treated as capital.
The “Marren v Ingles” position matters because it creates a potential double tax exposure — once on the estimated value of the right at completion, and again if the actual receipt exceeds expectations. Well-advised sellers can sometimes restructure the earn-out to avoid or reduce this exposure.
Share-based earn-outs
Earn-outs paid in shares of the acquirer (rather than cash) can sometimes access share-for-share rollover relief, deferring the CGT until the subsequent disposal of the acquirer’s shares. This is technical and depends on specific conditions being met.
Loan note rollovers
Where consideration is received in the form of loan notes — either vendor loan notes or deferred consideration loan notes — specific rollover reliefs may apply depending on whether the notes are classified as “qualifying corporate bonds” (QCBs) or “non-qualifying corporate bonds” (non-QCBs). The choice of classification has significant CGT implications and is typically negotiated at SPA stage.
The over-riding point
The tax position of UK earn-outs and deferred consideration is technical, depends on specific facts, and changes with legislative updates. The comments above are general — they are not tax advice and they do not address every situation. Every seller receiving earn-out or deferred consideration should obtain specialist tax advice before completion from an advisor with direct UK M&A experience. The cost of the advice is typically trivial relative to the tax exposure it protects against.
Protecting Both Sides During the Earn-Out Period
The earn-out period is a commercial and legal minefield. Buyers and sellers have fundamentally different interests during the period, and the SPA needs to anticipate the predictable conflicts and provide mechanisms for dealing with them.
Seller protections typically negotiated
- Operational covenants: the buyer commits to running the business in a manner that does not artificially suppress earn-out performance — e.g. no diversion of business to other group companies, no unilateral changes to accounting policies, no unusual capex cuts or investment decisions
- Information rights: the seller receives regular management accounts and the information needed to monitor earn-out performance
- Termination protections: specific circumstances in which the seller’s employment can be terminated are defined narrowly, with broader termination triggering acceleration or automatic payment of the earn-out
- Change of control triggers: if the buyer sells the target during the earn-out period, the earn-out typically accelerates or settles at a formulaic valuation
- Dispute resolution mechanisms: detailed provisions for independent expert determination of earn-out calculation disputes
Buyer protections typically negotiated
- Operational control: the buyer retains ultimate decision-making authority despite the operational covenants, with agreed mechanisms for handling disagreements
- Caps and collars: maximum earn-out payment defined, potentially with adjustment mechanisms if performance is achieved through channels the buyer considers inappropriate
- Offset rights: the ability to offset warranty claims or indemnity claims against earn-out payments otherwise due
- Business combination protections: ability to integrate the target into the buyer’s wider business without triggering seller claims, subject to ring-fencing for earn-out measurement
- Accounting policy specification: detailed SPA schedules defining exactly how earn-out metrics are calculated to minimise later interpretation disputes
The critical SPA schedule
Every earn-out SPA includes a detailed schedule defining the earn-out metric calculation. This schedule is often 10-30 pages and addresses items such as: accounting policies to be applied, specific items to be included or excluded, treatment of exceptional items, allocation of shared costs, transfer pricing between group companies, and the process for finalising the calculation at each measurement date. Time spent getting this schedule right at SPA stage pays back many times over in reduced disputes.
Common Earn-Out Disputes and How to Avoid Them
Earn-out disputes are common and costly. Recognising the predictable patterns helps both parties structure deals to minimise conflict and gives finance leaders on either side early warning of issues that may escalate.
Common dispute patterns
- Disputed cost allocations: costs allocated from the buyer’s wider group to the target that reduce earn-out metric performance. Particularly contentious where the allocation basis was not specified in the SPA.
- Accounting policy changes: post-completion changes to accounting policies (inventory valuation, revenue recognition, bad debt provisions) that alter the earn-out calculation relative to how it would have been under the pre-completion policies.
- Transfer pricing: intercompany transactions between the target and other group companies priced on terms that depress the target’s earn-out metrics.
- Exceptional item classification: disagreement over whether particular costs are exceptional (and excluded from earn-out calculation) or recurring operating costs (included).
- Strategic decisions: buyer decisions that reduce short-term earn-out performance (e.g. increased investment, strategic repositioning) but are argued to be in the long-term interest of the business.
- Termination disputes: disagreement over whether a seller’s termination was for good leaver reasons (preserving earn-out) or bad leaver reasons (forfeiting it).
- Growth through acquisition: whether earn-out metrics include or exclude the contribution of businesses acquired by the target during the earn-out period.
How to prevent disputes
The most effective dispute prevention happens at SPA stage:
- Detailed, unambiguous earn-out calculation schedules with worked examples
- Specific accounting policy specifications that cannot be varied without joint agreement
- Clear cost allocation methodologies with defined bases and review mechanisms
- Acquisition treatment rules specified in advance — include, exclude, or pro-rata
- Independent expert determination mechanisms for genuine calculation disputes
- Seller information rights sufficient to monitor the calculation without requiring full operational control
How to manage disputes when they arise
When disputes do emerge, early engagement typically resolves them more efficiently than late escalation. The finance leaders on both sides have a significant role here — their ability to engage technically, constructively, and without emotional escalation often determines whether a dispute resolves commercially or ends in formal expert determination or litigation.
The CFO’s Role in Earn-Outs — Structuring and Managing
The CFO plays a central role in every stage of an earn-out — from initial structuring through SPA negotiation, operational measurement during the period, and final calculation and payment.
CFO role pre-SPA (seller side)
- Modelling the earn-out impact on the seller’s overall proceeds under different performance scenarios
- Advising on which metrics to prefer and which to resist based on the business’s operational reality
- Working with legal advisors to draft the earn-out schedule in sufficient detail to minimise later disputes
- Identifying operational covenants that protect the seller’s earn-out economics without being commercially unreasonable to the buyer
- Engaging with tax advisors to optimise the structure within applicable tax rules
CFO role pre-SPA (buyer side)
- Validating the achievability of the performance metrics in the buyer’s base case
- Designing caps and floors that reflect the buyer’s risk appetite
- Anticipating operational changes post-completion and ensuring the SPA allows for them without creating dispute risk
- Coordinating with the accounting function on how contingent consideration will be booked and subsequently re-measured
- Modelling the P&L volatility implications for the acquirer’s subsequent reporting
CFO role during the earn-out period
- Operating the earn-out measurement system consistently with the SPA specification — this is often a separate reporting track from the rest of the business’s management information
- Preparing the interim and final earn-out calculations for presentation to the other party
- Managing the information flow to the seller under the SPA’s information provisions
- Identifying and flagging potential dispute areas early
- Supporting dispute resolution processes if they arise
Why the CFO matters disproportionately
Earn-out value is highly sensitive to technical decisions that only the CFO is positioned to make well. A CFO with earn-out experience adds measurable value on both sides of a transaction by structuring deals that actually deliver the commercial intent and by managing the post-completion period in ways that avoid value destruction through unnecessary disputes. See our Investor Ready CFO guide for the broader capabilities required in transaction-intensive environments.
How FD Capital Supports Earn-Out Work
FD Capital places CFOs, FDs and specialist finance leaders into UK businesses where earn-out structuring and management is a core part of the role — both for sellers preparing for or executing exits with earn-out structures, and for buyers managing earn-out measurement and the associated post-completion work across acquired portfolios.
Our earn-out-relevant capabilities
- Pre-sale CFO placements: finance leaders placed into target businesses 12-18 months before an intended sale process, specifically to prepare the business financially and support the structuring of the transaction including any earn-out components. See our Business Exit Preparation page.
- Earn-out management CFO placements: CFOs placed into newly-acquired businesses where the seller’s earn-out runs for 1-3 years and the business needs a finance leader capable of handling both operational finance and earn-out measurement across that period.
- Interim transaction CFOs: experienced finance leaders placed for specific transaction phases on an interim basis. See our Interim CFO and Fractional CFO pages.
- Buy-side CFO placements: CFOs placed into active acquirers running multiple acquisitions with earn-out structures. See our Private Equity CFO Search and CFO Recruitment for PE-Backed Businesses.
- Dispute-period finance leaders: interim finance leaders brought in specifically to manage contested earn-out periods where the original CFO has departed or where specialist earn-out expertise is required.
Where we add the most value
The CFOs we place into earn-out-heavy environments add measurable value by reducing the risk of disputes through better SPA drafting, more rigorous post-completion measurement, and cleaner operational handling of the earn-out period. The cost of a weak CFO on either side of an earn-out can easily exceed several years’ worth of that CFO’s fees through avoidable disputes and suboptimal structural decisions.
Earn-Outs Matter — Get the Finance Leadership Right
Earn-outs and deferred consideration are core features of UK mid-market M&A practice, structural tools that bridge valuation gaps, transfer forecast risk, and keep key people engaged post-completion. They are also technically complex, legally intricate, and operationally demanding. The businesses that handle them well — on both the seller and buyer sides — consistently extract more value from their transactions than those that treat them as afterthoughts in the SPA. The businesses that handle them poorly routinely end up in disputes that cost years of management time and millions of pounds of economic value, or in structures that fail to deliver the commercial intent that motivated their use.
FD Capital places the CFOs and Finance Directors who make UK earn-out-heavy transactions work. Whether you are preparing a business for sale, working through a live transaction with earn-out elements, operating an acquired business during an earn-out period, or running a buy-and-build programme with multiple concurrent earn-outs, the finance leader at the centre of this work is one of the highest-leverage appointments you can make. Our Private Equity practice and broader CFO for Fundraising pages cover our full transaction-focused recruitment practice.
A Note from Our Founder — Adrian Lawrence FCA
Earn-outs are one of those transaction elements where the difference between a well-structured deal and a badly-structured one shows up years later, long after the legal and advisory teams have moved on, when the seller and buyer are either negotiating an earn-out payment or arguing about one. I have seen both kinds up close — earn-outs that delivered exactly what both parties intended, and earn-outs that created multi-year commercial conflict over technical issues that should have been resolved at SPA stage. The pattern is consistent: the deals where the CFO on one or both sides had direct earn-out experience before consistently produced cleaner outcomes than deals where the CFO was handling earn-outs for the first time. The technical complexity of earn-outs and the commercial leverage they involve make this one of the specific CFO capabilities that genuinely adds value on specific mandates.
At FD Capital we place CFOs and Finance Directors into UK businesses where earn-out structuring, management, and resolution is a meaningful part of the role. Pre-sale preparation, active transaction execution, post-completion operating under earn-out conditions, and buy-side portfolio management across multiple concurrent earn-outs — each is a specialist context requiring specific experience. The finance leaders in our network who work in these environments tend to have seen multiple earn-out cycles through to conclusion, which is a different category of capability from general M&A experience. If you are at any stage of this work, I would be happy to have a direct conversation about the profile that fits your specific situation.
Earn-outs often end up being the most consequential clauses in a UK mid-market SPA. Treat them accordingly.
