Merger and Acquisitions CFO

M&A CFO Services and Recruitment

FD Capital places fractional, interim, and permanent CFOs with specialist mergers and acquisitions experience for UK businesses — from owner-managed businesses going through their first acquisition to PE-backed platforms executing multi-deal buy-and-build strategies. Adrian Lawrence FCA, founder of FD Capital and a Fellow of the ICAEW, oversees every M&A CFO mandate personally. Our network includes CFOs who have led the finance workstream on acquisitions, disposals, MBOs, and carve-outs — with the technical depth to manage due diligence, completion accounts, and post-completion integration without external hand-holding.

Transactions expose the limitations of a finance function quickly. An acquisition that proceeds without an experienced CFO at the table risks completion account disputes, undisclosed liabilities, earn-out disagreements, and integration failures that erode the value the business paid to acquire. An experienced M&A CFO protects against each of these risks — from the first due diligence request through to the final integration report. FD Capital has placed M&A-experienced CFOs since 2018.

Call 020 3287 9501 or email recruitment@fdcapital.co.uk. Shortlists typically delivered within three to seven working days.

“Adrian worked with us as our Fractional CFO for six months and we are genuinely grateful for the contribution he made. His financial expertise and calm, professional approach gave us confidence in our numbers and supported better decision-making across the business. I would recommend Adrian and FD Capital without hesitation.”

The CFO’s Role in Mergers and Acquisitions

The CFO is the most important person in the room on either side of an M&A transaction. On the buy side, the CFO leads financial due diligence, models the transaction economics, structures the deal, and manages the integration. On the sell side, the CFO prepares the business for sale, manages vendor due diligence, and maximises the value achieved at completion. In both cases, the depth and quality of the CFO’s M&A experience directly affects the transaction outcome.

Financial due diligence

Buy-side financial due diligence is the process of verifying the target’s financial position — confirming the quality of earnings, identifying normalisation adjustments, assessing working capital, and surfacing any financial risks that affect the purchase price or the terms of the deal. An experienced M&A CFO understands what the due diligence advisers are looking for, can challenge their findings with authority, and ensures the board is making acquisition decisions on accurate financial information. The ICAEW’s corporate finance and due diligence guidance sets the professional standards that FD Capital’s M&A CFO candidates are expected to meet.

Sale and Purchase Agreement — financial provisions

The financial provisions of the SPA — price adjustment mechanisms, representations and warranties, indemnities, and locked-box versus completion accounts structures — are the CFO’s technical territory. An M&A CFO who has negotiated SPA financial provisions in prior transactions understands how to protect the buyer’s or seller’s position without unnecessarily inflaming commercial negotiations. A CFO without this experience will rely on advisers at every stage, increasing cost and reducing negotiating effectiveness.

Completion accounts

Where a transaction uses a completion accounts mechanism, the CFO is responsible for preparing or reviewing the completion accounts in strict accordance with the SPA’s accounting policies — and for managing any disputes that arise through the completion accounts process. Disputes over working capital, debt, and cash definitions at completion are common and can involve significant sums. A CFO who has been through a contested completion accounts process understands the commercial and technical stakes in a way that a first-time participant cannot.

Earn-out management

Earn-out provisions — where part of the purchase price is contingent on the acquired business achieving specific financial targets post-completion — are both technically complex and commercially sensitive. The M&A CFO must ensure that the earn-out accounts are prepared in accordance with the SPA’s definitions, that EBITDA adjustments are correctly treated, and that the process is managed without creating unnecessary disputes between buyer and seller. CFOs who have managed earn-out periods in prior transactions are significantly more effective at navigating these arrangements.

Post-acquisition integration

The finance integration — combining accounting systems, chart of accounts, management reporting frameworks, treasury arrangements, and financial controls — is one of the most demanding aspects of a post-acquisition period. An experienced M&A CFO brings an integration playbook rather than starting from scratch: a structured approach to Day 1 finance readiness, a 100-day integration plan, and the experience to prioritise the finance workstreams that protect the business while the integration proceeds. Research published by the BVCA consistently identifies finance integration as one of the primary value drivers in PE-backed acquisitions — and one of the most common sources of value destruction when managed poorly.

M&A CFO by Transaction Type

M&A CFO requirements vary by transaction type. FD Capital’s network covers experienced CFOs across the full range of acquisition and disposal structures.

PE-backed buy-and-build acquisitions

Private equity-backed businesses executing buy-and-build strategies require CFOs who can manage multiple acquisitions simultaneously — running parallel due diligence processes, integrating acquired businesses onto the platform’s financial infrastructure, and reporting acquisition performance to the PE board. This is one of the most demanding M&A CFO environments and requires candidates with specific prior experience of PE-backed acquisition programmes. See our CFO recruitment for PE-backed businesses and private equity FD pages for related profiles.

Owner-managed business acquisitions

Owner-managed businesses acquiring for the first time often lack internal M&A finance capability entirely. A fractional or interim CFO engaged specifically for the transaction provides the financial due diligence leadership, SPA support, and integration planning the business needs without a permanent full-time appointment. Our outsourced CFO service is well-suited to this model — an experienced M&A CFO engaged for the duration of the transaction and retained on a lighter fractional basis thereafter.

Management buyouts and MBIs

MBOs and MBIs present specific CFO challenges — financing structure, lender reporting obligations, management incentive scheme accounting, and the transition from a corporate finance structure to a standalone business. The CFO of an MBO vehicle must manage the relationship with senior and mezzanine debt providers, ensure covenant compliance from Day 1, and implement the financial reporting infrastructure that the new ownership structure requires. CFOs who have been through an MBO process have a practical understanding of these demands that no amount of general M&A experience substitutes.

Distressed acquisitions and carve-outs

Acquiring a distressed business or carving out a subsidiary from a larger group requires CFOs with experience of accelerated timelines, incomplete financial records, and the specific accounting challenges of separating an entity from its parent group — including shared services, intercompany balances, and transfer pricing arrangements. FD Capital’s network includes CFOs with carve-out and distressed acquisition experience who can operate effectively under time pressure and with incomplete information.

Disposals and exit preparation

CFOs preparing a business for sale must ensure the financial records are audit-ready, the management accounts are investor-grade, and the financial story is coherent and defensible. Vendor due diligence preparation, information memorandum financial sections, and the financial aspects of the data room all fall to the CFO. A CFO who has taken a business through a sale process understands what buyers and their advisers scrutinise most closely. See our IPO CFO recruitment page for businesses considering a public market exit.

Engagement Models for M&A CFOs

Fractional M&A CFO

The most appropriate model for businesses that have an existing finance team but lack CFO-level M&A capability — a fractional CFO engaged specifically to support a transaction, working alongside the existing team for the duration of the deal. After completion, the engagement can continue at a reduced level to support integration and earn-out management. See our fractional CFO service for how this model works in practice.

Interim M&A CFO

Full-time or near-full-time cover for a defined transaction period — typically from the point of exclusivity through to 90-120 days post-completion. Interim M&A CFOs can start at short notice and are accustomed to working intensively on transactions without a long induction. See our interim CFO recruitment page for availability and terms.

Permanent M&A CFO

Appropriate for PE-backed businesses and active acquirers where M&A capability is a permanent requirement of the CFO role. All permanent mandates are conducted as retained executive searches with shortlists within three to seven working days. See our CFO recruitment page for the full permanent appointment process.

What to Look for in an M&A CFO

Transaction track record. The number of transactions a CFO has personally led — not just observed — is the most important differentiator. A CFO who has been the primary finance lead on five or more completed transactions brings a depth of practical experience that cannot be replicated from advisory work alone.

Buy-side and sell-side experience. CFOs who have been on both sides of a transaction understand the motivations and tactics of both parties — making them more effective negotiators on financial provisions and more credible in investor processes.

Financial due diligence depth. The ability to direct, challenge, and synthesise due diligence findings — not just commission them — is the hallmark of a genuinely experienced M&A CFO. FD Capital specifically assesses candidates on the quality of their due diligence experience.

Integration leadership. Post-acquisition integration is where a significant proportion of transaction value is won or lost. CFOs with a structured approach to finance integration — systems, reporting, controls, team — can demonstrate a track record of successful post-completion periods.

Professional qualification. The majority of M&A CFOs in FD Capital’s network are ACA-qualified from the ICAEW, typically with Big Four or mid-tier accounting firm backgrounds that provided the financial due diligence and corporate finance foundations the role demands.

Frequently Asked Questions

At what point in a transaction should we bring in an M&A CFO?

Ideally before exclusivity — from the point of initial financial assessment of the target. Bringing in an experienced M&A CFO at the heads of terms stage allows them to shape the financial due diligence scope, identify risk areas early, and ensure the SPA financial provisions are structured appropriately. CFOs brought in after exclusivity are working under time pressure and may miss issues that earlier involvement would have surfaced. FD Capital can identify and introduce M&A-experienced CFOs at short notice for businesses that need to move quickly.

Can a fractional CFO manage an acquisition alongside existing responsibilities?

This depends on the scale of the transaction and the intensity of the due diligence process. For a straightforward bolt-on acquisition with a well-prepared target, a fractional CFO working two to three days per week can manage the transaction alongside their other responsibilities. For a complex acquisition with contested due diligence findings or a tight timeline, a higher day commitment — or a dedicated interim CFO for the transaction period — is more appropriate. FD Capital will advise on the right resource model based on the transaction specifics.

Do you place CFOs with specific sector M&A experience?

Yes. FD Capital can identify M&A CFOs with transaction experience in specific sectors — financial services, technology, professional services, manufacturing, and healthcare among others. Sector-specific M&A experience is particularly valuable where the due diligence scope includes regulated assets, intangible-heavy businesses, or sector-specific accounting treatments. Tell us the sector and transaction type at the brief stage and we will calibrate the candidate profile accordingly.

What is the difference between an M&A CFO and a corporate finance adviser?

A corporate finance adviser — an investment bank, M&A boutique, or Big Four CF team — provides deal origination, valuation, and transaction management advisory services. The M&A CFO is an executive finance professional embedded in the acquiring or selling business, responsible for the buyer’s or seller’s financial position through the transaction. The two roles are complementary — the CFO works alongside the corporate finance advisers, challenging their output and ensuring the board makes decisions on accurate financial information. FD Capital places CFOs; for corporate finance advisory, see the ICAEW Corporate Finance Faculty for accredited advisers.
