M&A due diligence for corporate development teams

Every detail matters for corporate development teams identifying M&A targets. PitchBook has in-depth data to help the due diligence process.

Worldwide M&A deal value reached $3 trillion in 2023—a 35.5% drop from 2021’s all-time peak of $4.7 trillion, according to PitchBook’s 2023 Annual Global M&A report. Though last year was M&A’s second-weakest year in a decade, the rates of decline appear to be slowing and 2024 shows promise that the worst may be behind us, PitchBook analysts say.

As valuations finally show signs of stabilization, companies are more willing to sell again, suggesting M&A activity could pick back up in the year ahead—an exciting outlook for corporate development teams.

What is corporate development?

Corporate development is a business function of a company focusing on growth strategy. Many companies staff a corporate development team dedicated to these initiatives.

Tim Van Tuyle, a member of the corporate development team at leading cybersecurity company and PitchBook client Palo Alto Networks, explains how his work supports other teams within the business.

Our business units focus on building great products internally, and they ask us to have a perspective on what's going on externally in the industry. We try to identify external innovation by being data-driven and objective, so we use PitchBook to inform our teams on market activity."

Teams like his create and pursue growth opportunities, long-term success, and competitive developments through mergers and acquisitions.

What is M&A?

Mergers and acquisitions (M&A) are deals involving the consolidation of companies through a financial transaction.

Though often used interchangeably, mergers and acquisitions do represent different kinds of transactions. A merger, also known as a merger of equals, happens when two similarly sized companies come together and form a single entity. An acquisition takes place when one company purchases another and establishes itself as the owner.

The type of target a company selects often reflects the type of growth strategy the merger or acquisition hopes to accomplish.

Common types of M&A

Horizontal merger

  • The merging of two or more companies operating in the same industry
  • Purpose: Allows a company to immediately gain market share and reduce competition

Product extension merger

  • A type of horizontal merger combining two or more companies producing similar products in similar markets
  • Purpose: Enables the companies to group their products and access more consumers

Market extension merger

  • A type of horizontal merger combining two or more companies producing similar products in different markets
  • Purpose: Allows a company to gain access to a new market and customer base

Conglomerate M&A

  • The merging of two or more companies operating in different industries
  • Purpose: Helps a company achieve diversification of industry and customer base

Vertical merger

  • The merging of two or more companies that occupy different parts of the supply, delivery or value chain for any given product or service
  • Purpose: Helps to reduce costs and can allow a company to directly access materials and production capabilities

Reverse merger

  • A business combination between two companies with the smaller of the two (a public company) emerging as the surviving entity
  • Purpose: Allows a private company to trade publicly without going through an IPO process

What is due diligence?

Simply put, due diligence is an investigative assessment of a company’s performance, financial health, and strategic fit. It is a crucial step in dealmaking for accurately verifying and cross-checking information. During the due diligence process, an acquiring company will fastidiously examine every part of a target company, including historical and current financial statements, all available documentation, intellectual property and software, HR and culture, legal records, and so much more.

This process helps an acquiring company understand how their target’s business works, and whether it is a good fit as an investment. It also assists in mitigating risk. Just as a buyer of a home would conduct a thorough inspection for water damage or structural problems, an acquirer of a company uses due diligence to uncover legal troubles, compliance issues, or any other risky activities.

Good due diligence can help or challenge an acquiring company’s target selection. Van Tuyle explains how corporate development teams are involved in this process.

It’s easy for anyone to have preconceived notions about the quality of a potential new sector. We can inform our teams with data on how the market is reacting to a trends and how investors are capitalizing on it to help determine if it is something we should further investigate.”

Van Tuyle notes that beyond evaluating whether a selected target is a good strategic fit, due diligence also helps identify the likelihood of a target’s availability and growth trajectory.

If a company has recently raised a large round, they may be less open to acquisition. Headcount trending can also be an interesting data point. We can use those kinds of signals to refine our strategy of engaging with potential acquisition targets.”

Importance of due diligence for corporate development

When it comes to performing due diligence, corporate development teams are intentional and thorough. Logan Atkins, Investment Banking VP at PitchBook client AGC Partners, describes his experience of supporting corporate development teams.

Corporate development teams come back with very specific questions about the product, the technology, the competitive landscape, and the employee census and headcount.”

As part of the due diligence process, the target company will provide relevant documentation, but Van Tuyle knows that what they share doesn’t always reflect the full story. That’s where a comprehensive data provider comes in.

Every briefing we put together for our internal teams includes data from PitchBook to fill in the gaps of what we've learned from other outside sources.”

In the due diligence process, catching small details may be the difference between a successful deal and a risky outcome. Ideally, irregularities would be identified earlier in the process, but certain details are sometimes not fully considered in the right context until the due diligence stage. This thorough investigation gives M&A professionals a better and fuller perspective of the information they’re reviewing.

Gaining insight into financing histories, series terms, cap tables, revenue figures, and more gives corporate development teams confidence as they pursue an M&A deal.
