Buy-side M&A: a practical guide for acquirers in South Africa
The process, the sale-agreement mechanics, and the merger-notification thresholds that changed for the first time since 2017.
Buy-side, defined against the alternative
Most M&A advice is written from the seller’s side, because most owners only sell once and need the most help. Buy-side work is different in kind, not just direction: the acquirer is usually a repeat player, the process is proactive rather than reactive, and the core skill is discipline — knowing which targets to walk away from is as valuable as knowing how to close the ones worth pursuing.
Buy-side mandates fall into a few recognisable shapes: a strategic acquisition buying a competitor, supplier or capability; a roll-up or buy-and-build strategy consolidating a fragmented sector; a management buyout, where the buyer is the existing team — covered in full in our management buyout guide; and a private equity-backed acquisition, where a fund provides the capital behind an operating buyer. The process below applies to all four, with the financing and governance detail differing by type.
The process, end to end
Target identification and screening. Before any approach, define the acquisition criteria precisely — sector, size, geography, what the target must already have (customers, licences, a management team that stays) — and screen against it systematically. Most wasted buy-side time goes into pursuing targets that were never a real fit.
Approach and indicative offer. A non-binding indicative offer or letter of intent sets out price range, structure and key conditions, giving both sides a basis to decide whether detailed work is worthwhile before either commits real cost to it.
Due diligence. Financial, legal, tax and commercial diligence tests whether the business is what it appeared to be from the outside — verifying financials, contracts, liabilities, and any dependency on the current owner. This is where most acquisitions are won or lost: a rigorous process here prevents the far more expensive discovery of a problem after completion.
Sale agreement negotiation. Price, warranties, indemnities, conditions precedent and the allocation of risk between buyer and seller are negotiated into a binding agreement. Warranties and indemnities are where diligence findings get translated into contractual protection — a diligence finding not reflected in the agreement offers no real protection at all.
Completion and integration. Funds move, ownership transfers, and—the step acquirers most often under-resource—the target is integrated into the buyer’s business. A well-structured deal that is poorly integrated afterwards routinely destroys more value than a mediocre deal integrated well.
The 2026 merger notification change every acquirer should know
South Africa’s merger control thresholds changed materially from 1 May 2026 — the first revision since 2017. Only intermediate and large mergers require mandatory notification to the Competition Commission; small mergers generally do not, though the Commission can still call one in within six months of implementation.
The revised thresholds: an intermediate merger now requires the combined annual turnover or asset value of acquirer and target to reach R1 billion (up from R600 million) and the target alone to reach R200 million (up from R100 million). A large merger — notifiable to both the Commission and the Competition Tribunal — now requires a combined threshold of R9.5 billion (up from R6.6 billion) and a target threshold of R280 million (up from R190 million). Filing fees rose alongside the thresholds: R220,000 for an intermediate merger and R735,000 for a large one.
The practical effect: a meaningful band of mid-market acquisitions that previously required mandatory notification — and the cost and timeline that comes with it — now fall below the threshold entirely. Every acquisition currently in a pipeline is worth re-tested against the new numbers rather than assumed to sit where it did under the old regime.
What actually kills acquisitions
Three failure modes recur across buy-side processes far more than any dramatic collapse.
Chasing the deal instead of the strategy. A target that stops fitting the original acquisition criteria but keeps moving forward on momentum alone is the single most common cause of a bad acquisition — the discipline to walk away is a buy-side skill, not a failure of one.
Diligence findings that never reach the agreement. A concern identified in due diligence but not translated into a price adjustment, a warranty, or a specific indemnity offers the buyer no actual protection — it was, in effect, diligence performed for no purpose.
No integration plan before completion. Acquirers who plan the transaction in detail and the integration not at all routinely lose the value the acquisition was meant to create. The integration plan should exist, at least in outline, before the sale agreement is signed — not after.
Where Caban fits
We advise acquirers on the buy-side of a transaction: defining and screening against acquisition criteria, structuring the offer and the financing behind it, running or overseeing due diligence, and negotiating the sale agreement through to completion. If capital is part of the question, our guides to private equity and growth funding cover the routes; if you are the target’s current owner rather than the acquirer, how to value a business for sale is the place to start instead. If you have a specific acquisition in mind, that is a conversation worth having before an offer goes in, not after.
Questions, answered
What is buy-side M&A?
Buy-side M&A is mergers and acquisitions work done from the acquirer's side of the table — finding and screening targets, making an offer, running due diligence, negotiating the sale agreement, and closing. It differs from sell-side work, which represents the business being sold.
How long does a buy-side acquisition take in South Africa?
Commonly four to nine months from an indicative offer to completion, depending on the complexity of due diligence, financing, and — where applicable — Competition Commission merger notification and approval timelines.
Do I need to notify the Competition Commission of an acquisition?
Only intermediate and large mergers require mandatory notification. From 1 May 2026, an intermediate merger requires combined acquirer-and-target turnover or assets of R1 billion (target alone R200 million); a large merger requires R9.5 billion combined (target alone R280 million). Many mid-market deals now fall below these thresholds entirely.
What is the biggest risk in buy-side M&A?
Diligence findings that are identified but never translated into the sale agreement — as a price adjustment, a warranty, or a specific indemnity — leave the buyer with no real protection. The second most common risk is chasing a target that has stopped fitting the original acquisition strategy.
