Due diligence checklist for private equity firms

Data from Crunchbase reveals that while private capital deal volume dropped to historically low levels in 2023, late stage funding has begun its rebound. More deals are being done, and this increases competition in a market where the qualifier for a "high quality deal" has narrowed significantly.

Finding deals that produce a return on investment is not an easy task. That’s where an effective due diligence process—not just deal origination—can be a differentiator for a private equity (PE) firm.

Conducting due diligence is how PE deal teams figure out if a deal is worth pursuing, or if it’s time to walk away. The average PE firm evaluates 80 deals before investing in a single company—and closing a deal takes an average of 20 meetings, four negotiations with target companies, and 3.1 full-time deal team members. So winning firms are the ones that can conduct due diligence this quickly and comprehensively.

Once your PE deal team has identified a potentially good deal, it’s time to conduct thorough due diligence. Your team is looking for information around the target company’s financials, legal aspects, IT, operational processes, and so much more. It’s critical that your firm has a process for this complex task so you can minimize the risks when investing in a privately held company.

Private equity investments are complex deals with long time horizons—and your firm’s private equity funds, time, resources, and reputation are on the line. Follow the advice in this article to evaluate all the right factors, mitigate risks, and find strong companies for your limited partners to invest in.

You’ll learn more about private equity due diligence best practices. You’ll also find a PE due diligence checklist template that your deal team can use as a starting point to improve and accelerate your PE firm’s due diligence process.


What makes the private equity due diligence process unique?

The purpose of due diligence may be the same for private equity as it is for other investment teams: to minimize risk and maximize value for investors. But many of the focus areas differ from venture capital and investment banking.

To improve the odds that a PE deal will yield a return for your firm and its LPs, your deal team must gather information about the target company, the seller, and the assets for sale, then put together the best purchase plan and price. The due diligence strategy for a PE deal will be driven by the PE fund’s investment thesis and strategy for building value.

Much of the private equity due diligence process is guided by the confidential information memorandum (CIM). This is a long document—often upwards of 50 pages in length—that the seller provides that includes information like:

  • Basic financial data
  • Overview of the management team
  • Competitive landscape
  • Products, services, and pricing strategy
  • Customer base

Because the CIM can often be so long, it can appear at first glance to be comprehensive. But smart PE deal teams don’t rely solely on the CIM to make investment decisions. Rather, they use the CIM as a starting point for further due diligence.

What private equity firms look for in an opportunity is different from venture capital in many ways—but one primary difference is that while VCs are looking for strong founders and strong company performance, PE firms are often looking for problem areas. The firm can get a better deal on a company that has problems that the PE firm can fix.

An underperforming management team is an example of a fixable problem. If the PE firm can acquire the struggling company at a discount, they can likely add value and improve performance by coaching or replacing the management team. This information is likely not in a CIM, however, and can only be uncovered by a savvy PE deal team that meets with managers, visits suppliers, and interviews customers.


Pass/fail screening questions for PE deal teams

The first thing a smart PE deal team will do is compare a potential investment against the fund’s investment criteria. Some companies can be immediately dismissed based on their financial profile, geography, or industry not aligning with the PE firm’s focus areas.

If the company passes that initial inspection, however, further criteria that may screen out potential bad fits include:

  • Revenue growth
  • Market position
  • Management team track record
  • Sustainable competitive advantages
  • Stable cash flow
  • Maintenance capital expenditure requirements
  • Favorable industry trends
  • Multiple avenues of growth

PE due diligence can be a lengthy, complicated process, so the faster you can say “no,” the more time you can spend doing due diligence on companies that will turn a profit for your firm.

What is a private equity due diligence checklist?

A PE due diligence checklist is a tool your deal team can use to gather information on, assess, and analyze potential PE deals.

A typical due diligence checklist for private equity will include finance, legal, tax, management team, and assets—but depending on the PE fund and the target company industry, you will likely add more categories to your due diligence checklist. For example, unlike VC firms, you’ll want to take a closer look at the management team and cash flow.

Your private equity due diligence checklist should be as comprehensive as possible and help you make as informed of a decision as you can. Some of the questions and requests for information will need to be sent to the seller in a due diligence questionnaire, but your deal team can also gather many of the data points in a desk study.

Which parts of due diligence does this checklist include?

Most VC due diligence checklists will cover these basic areas:

  • Finance
  • Tax
  • Legal
  • HR
  • Assets
  • IT
  • Competitive position
  • Total addressable market (TAM) and customer base
  • Capital requirements

  • Normal level of working capital required to run the business
  • Breakdown of capital expenditure versus operational expenditure
  • Breakdown of fixed versus variable COGS
  • Cycles and seasons of demand

Founder background

The management team may make the biggest difference in a target company’s future success as your PE firm’s portfolio company.
