Antitrust and Merger Control: What Sellers Need to Know

As a seller, you must know whether your sale is subject to merger control notification. If so, the process can extend by weeks or months. In worst cases, a buyer might use merger control as reason to reduce their bid or drop out entirely. Therefore, early understanding is critical.

Antitrust isn't complicated – but it's rule-based. With the right information, you can immediately see whether your sale is a hurdle or not.

German Competition Act (GWB) requires company acquisitions to be notified if two conditions are met: (1) the buyer will hold at least 25% interest in another company through acquisition (also indirectly). (2) Revenue thresholds: either buyer + target together have worldwide total revenue over 75 million euros, OR the target alone has German revenue over 15 million euros.

Practically: if you're selling a 20-million-euro business in Germany, almost every buyer on your list is subject to notification – meaning 2–4 weeks waiting while authorities review. If you're selling a 10-million-euro business and the buyer is significantly smaller, notification may not apply. Therefore: with your M&A advisor early clarify whether your sale is notifiable. This influences who competes and timing planning.

If your buyer is from another EU country or operates globally, EU antitrust rules may apply. The EU threshold is higher: a merger is notifiable if combined total revenues exceed 5 billion euros worldwide OR two have EU revenues over 250 million euros each. This matters when you sell to large international buyers.

Important: if a transaction exceeds both GWB and EU thresholds, sometimes you must notify twice – that drives timing up. Good sign: large buyers have antitrust counsel on staff and expect these procedures. They build waiting times into their timelines.

The notification process works like this: buyer or jointly with you files a notification (form with company info, revenues, market segments). Phase I (preliminary review): authorities have 25 working days to check for antitrust concerns. In standard cases they grant clearance. In critical cases (e.g., competitors merge) Phase II opens (detailed review), lasting 90 additional days – sometimes with requests for remedies ("I must divest XY customer relationships, then OK").

Best case: 25 days, then clearance. Worst case: Phase II, 90+ days, conditions. Your strategy: with antitrust counsel early assess whether Phase II risk exists. If yes, communicate that to buyer and keep timing flexible. With VALENTYR VOS Assessment we help identify these risks early – easing buyer selection and negotiations.

If your business has broad antitrust concerns with potential buyers (e.g., you're market leader in narrow segment), you must factor this into buyer search. Direct competitors are antitrust-problematic; financial investors (private equity) usually are not. This can guide your sales strategy.

Also: some countries (e.g., Turkey, Brazil, China) have their own merger control rules. When selling to buyers from these countries, waiting times multiply. With early assessment you can factor that in – and set realistic timing expectations.

With VALENTYR VOS Assessment we analyze not just your financials and assets, but also your market position: do you have market shares in narrow segments that raise antitrust concerns? Can you easily find buyers who are antitrust-safe? Or will your sale almost certainly need Phase II?

This helps you set realistic timing assumptions and focus buyer search. With VOS Autopilot (149 euros/month for businesses under 750k revenue) you regularly track how market changes (e.g., new competitors, market trends) affect your antitrust position.

Your steps: 1. With VALENTYR clarify whether your sale requires antitrust notification. 2. Involve antitrust counsel early (yes, it costs, but prevents surprises later). 3. Plan buyer search strategically – know who's antitrust-safe. 4. Budget timing flexibly: 2–4 weeks Phase I, possibly + 90 days Phase II. With clarity you sell smarter. Start this week.
