Mergers and Acquisitions CPD: Finance Skills for M&A Work

Mergers and acquisitions (M&A) are among the most significant transactions a business can undertake — and an area where finance professionals play a central, high-stakes role. Understanding what M&A involves, and the part finance plays, is valuable for anyone in finance, whether or not they work in the field directly. This guide explains what M&A is, why companies pursue it, what the process involves, and the role of finance — in clear, plain language. It complements our ACCA AFM guide, where M&A features.

What are mergers and acquisitions?

Mergers and acquisitions refer to transactions in which companies combine or one company takes over another. A merger typically describes two companies coming together to form a single combined entity, while an acquisition describes one company buying (taking control of) another. In practice the terms are often used together, as "M&A", to describe this broad area of corporate transactions. These are major, often complex deals, frequently involving significant sums and considerable planning, negotiation and execution. M&A is a key way that companies grow, reshape themselves, or change ownership — and because the stakes are high, getting these transactions right is hugely important, which is where careful analysis and finance expertise come in.

Why companies pursue M&A

Companies pursue mergers and acquisitions for a variety of strategic reasons, including:

• Growth — acquiring another company can be a fast way to grow, gaining its revenue, customers or capabilities.
• Synergies — combining businesses can create value, for example through cost savings or revenue opportunities.
• Market position — M&A can strengthen a company's position, expand into new markets, or acquire competitors.
• Capabilities and assets — acquiring technology, talent, products or other assets a company wants.
• Diversification — spreading into new areas or reducing reliance on existing ones.

The strategic rationale matters enormously, because M&A only creates value if the deal genuinely serves the company's strategy and is executed well — many deals fail to deliver the hoped-for benefits, so the underlying logic must be sound.

What the M&A process involves

An M&A transaction typically involves a number of stages. These can include identifying and evaluating targets (or, for a target, considering a sale), conducting due diligence (thoroughly investigating the other company's financial and other affairs), valuing the business and determining a price, negotiating the terms of the deal, arranging any financing, completing the legal and regulatory aspects, and then — crucially — integrating the businesses afterward. Each stage is important, and the process can be complex and demanding. Integration in particular is often where the success or failure of a deal is determined, as combining businesses well is challenging. Throughout, careful analysis and sound judgement are essential.

Why deals succeed or fail

It's well documented that a significant proportion of M&A deals fail to deliver the value originally hoped for — which makes understanding why deals succeed or fail valuable. Deals are more likely to succeed when there's a clear, sound strategic rationale, a realistic valuation (not overpaying), thorough due diligence that surfaces the risks, and — very importantly — effective integration afterward. Conversely, deals often disappoint when companies overpay, overestimate synergies, underestimate the difficulty of integration, or pursue a deal for weak strategic reasons. Recognising these factors highlights why careful analysis, realistic assessment and good execution — areas where finance plays a key part — matter so much. It also explains why M&A, despite its appeal, is an area where caution and rigour pay off.

The role of finance in M&A

Finance professionals play a central role throughout M&A. They're involved in valuation — estimating what a business is worth — which is critical to a deal. They contribute to financial due diligence, scrutinising the target's finances. They help with financial analysis and modelling of the deal and its likely effects. They're involved in arranging and assessing financing. And they support decision-making and, often, the financial aspects of integration. M&A draws heavily on core finance skills — analysis, valuation, modelling, due diligence and judgement — making it an area where finance expertise is genuinely central. For finance professionals, M&A can be a stimulating, high-impact area to work in, and understanding it is valuable even for those not directly involved.
