Why this matters more than it used to
Regulatory review has moved from a late-stage formality to something that shapes the buyer list. A transaction that would have completed without comment five years ago may now attract a national security review, a foreign subsidies notification, or a competition authority taking an interest in a deal below its own thresholds.
For a seller the practical consequence is that regulatory exposure differs by buyer. The same asset sold to a domestic sponsor, a European strategic and an Asian acquirer carries three different timetables and three different completion risks. That belongs in the buyer selection, not in the closing checklist.
Competition filings
Most jurisdictions require notification above size thresholds, and the thresholds are what determine whether you file rather than any judgement about competitive effect.
In the United States, a Hart-Scott-Rodino filing is required above a value threshold that is adjusted annually and currently sits near one hundred and twenty million dollars. The agencies have thirty days for an initial review, extendable by a second request which adds months.
In the European Union, the Merger Regulation applies above combined worldwide and EU turnover thresholds, with twenty five working days for a first phase review.
In the United Kingdom, the Competition and Markets Authority has jurisdiction on turnover or share of supply tests and can open an investigation into a completed transaction, which makes voluntary notification worth considering rather than assuming silence is safety.
In China, a filing to the market regulator is required above local turnover thresholds and review can run to a hundred and eighty days.
Foreign investment screening
The faster-growing area, and the one that catches technology deals disproportionately.
The Committee on Foreign Investment in the United States reviews acquisitions of control of a US business by a foreign person, with mandatory filing for certain technologies and for transactions involving sensitive personal data. Filing is voluntary in other cases, and voluntary filing is often the prudent course because the committee can review a completed transaction and require divestment.
The European Union's foreign subsidies regime requires notification where a subsidised acquirer buys an EU business above thresholds. Separately, most member states now run their own national security screening, as do the United Kingdom, Australia, Canada and Japan.
Technology businesses attract this scrutiny because of what they hold: critical technology, personal data at scale, or a position in a supply chain a government considers strategic.
Data, which is a separate problem
Cross-border transactions have to deal with where data sits and where it may move.
Personal data under the European regime, and the transfer mechanism that permits it to move to the acquirer's jurisdiction. Localisation requirements in several countries requiring certain data to remain physically in country. Sector rules for health, financial and government data that may restrict who can hold it at all.
These rarely block a transaction outright. They frequently change the structure, because the answer is often that some data stays behind or that a subsidiary continues to hold it, and that has commercial consequences for what is actually being bought.
Planning it properly
Map the exposure as soon as the buyer list exists, buyer by buyer rather than for the transaction generally. That map should inform which names are approached and in what order.
Build the timetable around it. A transaction requiring multiple approvals should carry three to six months beyond the ordinary schedule, and the seller should be clear whether they are willing to wait.
Condition the agreement carefully. Regulatory conditions, a long-stop date, and a reverse break fee where the buyer fails to obtain approval. Where the risk is significant, a hell or high water obligation requiring the buyer to accept whatever remedies are demanded shifts the risk to the party who created it.
Appoint counsel in each relevant jurisdiction early. Local knowledge of how an authority behaves in practice is worth more than knowledge of what the rules say.
Remedies
If an authority raises concerns, the options are a divestment of the overlapping activity, a behavioural commitment on pricing or access, a licensing obligation, or a structural separation keeping the acquired business at arm's length.
The parties who do well are the ones who identified the likely concern in advance and arrived with a proposed remedy rather than negotiating one under time pressure with a long-stop date approaching.
The seller's real decision
Whether to take a higher offer with regulatory risk or a lower offer that completes.
A bid that is fifteen percent better but carries a genuine chance of not completing after nine months is not obviously the better bid, because a failed process leaves the asset harder to sell and the business damaged by the wait. That trade is a board decision, and it should be made before the offers arrive rather than in the excitement of receiving them.
