The importance of due diligence in M&A

The excitement of a merger or acquisition often sits in the "big picture" strategy, but the success of the deal lives or dies in the details. Due diligence is not a box-ticking exercise. It is the point at which assumptions are tested, risks are priced, and uncomfortable questions are asked. This article explores why looking before you leap, by conducting a thorough due diligence, is the golden rule of mergers & acquisitions (“M&A”) transactions.

In the world of M&A, a signed Letter of Intent is celebrated as a victory. However, for the legal and financial teams, it really marks the moment the hard work begins. Between the first handshake and the final signature lies due diligence, the most crucial part of the deal.

Without a rigorous due diligence process, a buyer isn’t just acquiring a company’s assets; they are acquiring its skeletons. From undisclosed litigation to non-compliant contracts, the risks are substantial. Here is why due diligence is the ultimate insurance policy in any deal.

Financial reality checks

A target company’s financial statements tell a story, and due diligence verifies that story. While the target may show impressive EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation), a closer look can reveal a different picture. Are the revenue streams recurring or once-off? Are there “add-backs” that shouldn’t be there? Financial due diligence helps ensure that the price is based on maintainable earnings, not optimistic projections that disappear after closing.

What liabilities are you actually inheriting?

Legal due diligence is designed to uncover the liabilities, as many of the most serious risks never appear on a balance sheet. These liabilities may include:

  • Legal proceedings that could bankrupt the company.
  • Areas of non-compliance with various laws and regulations including; the Companies Act 71 of 2008,  tax laws,  and industry regulations.
  • Establishing “Change of Control” clauses in key client contracts that allow them to walk away the moment the deal is signed.

Identifying these risks early allows the legal team to draft specific warranties and indemnities in the transaction agreement, shifting the risk back to the seller.

Section 197 and cultural fit

The Labour Relations Act 66 of 1995 plays a massive role in M&A. Under Section 197, in the event of a business transfer as a going concern, employees generally transfer automatically to the new employer with their terms and conditions intact. 

Due diligence identifies:

  • Potential severance liabilities.
  • Unresolved CCMA disputes.
  • “Key Man” risks—if the founder leaves, does the business collapse?

Ignoring the human element is often the fastest way to destroy value post-integration, even where the legal mechanics of the deal are sound.

Intellectual Property ownership

For tech and brand-heavy companies, Intellectual Property (IP) is often the primary asset. However, assumption is dangerous. Does the company own its code, or was it written by a freelancer who never signed an IP assignment agreement? Is the trademark registered? If the target company doesn’t own the core asset they are selling, the deal is effectively void of value.

Deal breaker or price chipper?


Ultimately, the findings of a due diligence report serve two functions. First, they can be “Price Chippers”, allowing the buyer to negotiate a lower purchase price based on identified risks. Second, they can be “Deal Breakers”, signalling that the only winning move is to walk away. In M&A, information is leverage. A thorough due diligence process ensures you have enough of it to make the right call.

Protecting creators in the digital era – Copyright amendments

Nearly 5 decades after its original enactment, South Africa’s copyright regime is undergoing one of the most significant reforms in its history. The Copyright Amendment Bill [B13F-2017] introduces modern protections to secure the financial and digital interests of authors and performers, thereby strengthening their economic rights in an increasingly digital world. While parts of the Bill remain under constitutional review, a landmark 2025 court ruling has already enforced critical protections for users with disabilities. This article breaks down the primary measures intended to safeguard South African creativity.

Customary marriages stand equal

Customary marriages stand equal

In a landmark judgment delivered on 21 January 2026, the Constitutional Court pronounced welcomed clarity on the interplay between customary marriages, civil marriages, and antenuptial contracts (“ANC”). The Court, by majority decision in VVC v JRM and Others (CCT202/24) [2026] ZACC 2 (21 January 2026) , declined to confirm a High Court order that had declared section 10(2) of the Recognition of Customary Marriages Act 120 of 1998 (“the Recognition Act”) unconstitutional. The majority decision powerfully reaffirmed the equal constitutional status of customary marriages and established that spouses cannot unilaterally alter their matrimonial property regime without judicial oversight.

Merger threshold shake-up: What SA businesses should know

The Department of Trade, Industry and Competition (“DTIC”) has published draft amendments to South Africa’s merger notification thresholds, signalling a potential shift towards reducing regulatory red tape and easing the cost of doing business for merging parties. If implemented, the proposed changes would materially affect when mergers are required to be notified to the Competition Commission (“Commission”) and may result in fewer transactions being subject to mandatory approval.
