Due Diligence in M&A: What Buyers and Sellers Need to Know
What are mergers and acquisitions (M&A)? Right now, they may seem complex transactions, but this handy article aims to leave you feeling a little more enlightened - and confident - about them.
M&A transactions require careful planning and analysis, but don’t feel daunted by the process, which is designed to allow both buyers and sellers to assess the risks and opportunities of any given deal before finalising it.
In this article, we focus on the importance of financial, tax, and commercial due diligence, key considerations, and best practices for both buyers and sellers. While our expertise lies in these areas, we also work closely with trusted partners who can assist with legal, operational, and IT due diligence to provide a service you’ll be keen to make the most of.
What is due diligence?
Due diligence is the process of investigating and evaluating a business before entering into a transaction. It involves a thorough review of financial, operational, legal, and strategic aspects, to ensure that all risks are identified and mitigated.
For buyers, due diligence helps confirm that the business is worth the investment. For sellers, meanwhile, it provides an opportunity to address any issues in advance and ensure a smooth transaction. It really is win-win for both parties, like it was for a recent client of ours.
Our client, a private investor, was considering the acquisition of a family-run business in the retail sector. While the business demonstrated strong performance, our comprehensive due diligence revealed several concerns that could have significant consequences for future owners.
- VAT misstatements
During our review, we noticed discrepancies in the company’s VAT returns. Errors made by their accountants had resulted in underreported VAT liabilities over multiple quarters. This posed a risk of potential HMRC penalties and interest charges post acquisition. We worked with the sellers to correct the VAT errors and notify HMRC prior to completion.
- Personal expenses recorded as business costs
We identified several personal expenses, including family holiday costs and non-business related purchases, incorrectly recorded as business costs. This artificially reduced reported profits, leading to an understated corporation tax liability. Personal expenses were reclassified, providing a more accurate representation of the company’s profitability.
We used our findings to advise on the warranties and indemnities in the SPA to protect our client from potential historic tax exposures. The adjusted financials ensured a fairer valuation and protected the buyer from potential post-deal liabilities, giving them confidence in their investment.
