Transaction Services

No two transactions are ever the same. Whether buying or selling, refinancing or raising money, you need to identify risks early and uncover crucial information for negotiating the deal. We’re on the case.

Integrated deal advice – from preparation to completion and beyond.

At HaysMac, we help ambitious businesses and their owners navigate transactions with clarity and confidence. Bringing together corporate finance, transaction support, tax and private client expertise in one place, we provide joined-up advice that reflects both the commercial deal and the wider implications for shareholders.

Supporting deals at every stage

A successful transaction is rarely just about the deal itself. It is about preparation, timing, structure and what the outcome means for the people behind the business.

Our integrated transaction services and corporate finance expertise helps businesses get deal ready, navigate complex transactions with confidence and maximise value when it matters most.

Our support spans private and public market transactions.

For owner‑managed businesses, corporate groups and investors, we advise on acquisitions, disposals and strategic options.

For companies considering a flotation, our Capital Markets team brings extensive experience of acting as Reporting Accountant on IPOs and RTOs, helping management teams satisfy regulatory requirements, identify issues early and get the timing right.

How we can help

Our offering is anchored by corporate finance advisory and supported by a deep bench of transaction, tax and private client specialists. This means you have one team guiding you from initial ambition through to completion and beyond.

Corporate Finance

Corporate finance advisory at HaysMac is delivered by Green Square, a HaysMac company.

We advise owners, shareholders and management teams on disposals, acquisitions and strategic options, providing clear, independent advice from early preparation through to execution. We often engage several years ahead of a transaction to help strengthen value drivers and position the business for a successful outcome.

Our Corporate Finance team leads the process, working closely with specialists across due diligence, tax, valuations, financial modelling and capital markets to ensure decisions are commercial and aligned.

Corporate Finance

Equity Capital Markets

For businesses pursuing a public markets transaction, we provide the full range of Reporting Accountant services across the Main Market, AIM and Aquis, including accountants’ reports, long form reports, working capital reports and all comfort letters.

We also support businesses ahead of an IPO, helping reduce the burden on management teams later in the process. Alongside this, our Risk Assurance and Advisory team supports governance, risk and internal control readiness, ensuring you are prepared for the expectations of listed markets.

Due Diligence

Our dedicated financial and tax due diligence specialists enhance the chances of your transaction being successful. We add value through commercially focused advice, shaped by extensive experience supporting financial and strategic buyers and sellers through complex transactions.

Whether providing early ‘red flag’ reporting on an acquisition, vendor due diligence, vendor assistance or Sale and Purchase Agreement (SPA) support, we work collaboratively to strengthen your position, mitigate risks and transact with confidence.

Valuations

Our Valuations team helps our clients with company and share option valuations, Purchase Price Allocation (PPA) support, Weighted Average Cost of Capital (WACC) assessments, valuation of complex financial instruments, such as convertible loan notes and options and valuation advice on non-cash consideration for publicly traded securities (s593).

Tax in Transactions

Our business tax specialists help clients navigate complex tax issues with confidence, advising on exit planning, transaction structuring, due diligence, capital gains planning, tax reliefs, VAT recovery on deal fees and financing. We also support post-deal integration, group reorganisations, and ensure compliance with evolving anti-avoidance rules. Whether you're buying, selling, or restructuring, we deliver clear, practical end-to-end guidance tailored to your commercial objectives.

We also support private companies preparing for IPOs on the Main Market, AIM and Aquis with expert advice on tax structuring and pre-IPO health checks. From implementing tax-efficient employee share schemes to ensuring robust tax governance and international compliance, we help you present a clean, investor-ready profile.

Our goal is to minimise tax risk, maximise value and position your company for long-term success in the public markets.

Working in tandem, our private client tax specialists support founders, executives, and key stakeholders with personal tax planning, including capital gains strategies, share scheme optimisation, and post-exit wealth management. Together, we ensure a smooth, tax-efficient transition aligned with both corporate and personal goals.

Financial Modelling

Our tailored financial models help you diagnose opportunities, assess risk and inform performance planning. Built by experienced modelling and reporting specialists, they provide the clarity and credibility needed to facilitate better governance and business planning, support decision-making and meet stakeholder expectations.

Why choose Transaction Services with HaysMac?

Big Four capability with the personal touch

Choosing the right advisor can shape the outcome of a deal. Boutique firms bring focus but may often rely on external specialists to fill gaps. Larger firms offer breadth but may feel fragmented with multiple teams and layers between you and the people doing the work.

HaysMac sits between the two. You get a genuinely integrated team, without the complexity, and direct access to the people doing the work.

One team, fully aligned

Corporate finance, transaction support, tax, risk and private client specialists working together from day one. No duplication. No disconnect. Just clear, joined-up advice that considers both the deal and its wider impact.

Partner-led throughout

The team you meet stays involved from start to finish. We work as an extension of your team, bringing senior attention, continuity and a practical, collaborative approach. Nothing gets lost along the way.

Supporting you before the deal begins

Increasingly, we support businesses well ahead of a transaction. Whether you are planning a sale, investment or IPO, we help you prepare early, strengthen value drivers, manage risk and ensure both the business and its shareholders are ready when the opportunity comes.

Focused on getting the deal done

When the pressure builds, we bring clarity and momentum. We are hands-on, commercially focused and committed to getting deals over the line, identifying issues early and helping you act quickly.
