Entain is divesting one of its most resilient European operations, and the financials tell only part of the story. The gambling group has agreed to hand operational control of its Central and Eastern European joint venture to Czech investment firm EMMA Capital, marking the beginning of a complete withdrawal from the region. The move is counterintuitive because the assets at stake—Poland’s STS and Croatia’s SuperSport—remain market leaders generating consistent growth in their domestic markets.

The Numbers Don’t Add Up

On paper, there’s little reason for Entain to sell. The CEE business generated £522 million in net gaming revenue during 2025, with EBITDA climbing to nearly £184 million. Both figures represented roughly 7% year-on-year growth. Hardly the trajectory of a struggling operation.

Analysts have looked beyond quarterly performance to understand the real driver here, and the answer lies back in Britain.

The UK Tax Problem

The UK’s gambling tax overhaul has fundamentally altered the financial calculus for major operators. Remote gaming duty doubled from 21% to 40%, whilst sports betting duty jumped from 15% to 25%. These changes have pushed Entain’s effective tax rate on UK profits above 80 percent, an unwelcome shock that’s wiped roughly 30% from the company’s share price since the measures were announced.

Against this backdrop, selling a valuable overseas asset becomes attractive for balance sheet management. The transaction will reduce debt and lower annual interest costs, providing breathing room as the company absorbs the impact of higher domestic taxes.

Why Poland Was Never Going to Be Enough

Poland itself isn’t the problem. The market has demonstrated unusual resilience, with licensed operators adapting to a demanding tax environment that’s deterred many international competitors. Sports betting has expanded steadily, and market specialists regard the jurisdiction as a genuine opportunity.

The real constraint is structural. Private operators remain excluded from Poland’s online casino market, which operates under state monopoly. This restriction prevented STS from building the integrated sportsbook-and-casino model that’s become standard across regulated European markets. When Entain acquired STS for £750 million in 2023, management presumably anticipated eventual market liberalisation. Those hopes haven’t materialised.

Without access to the casino vertical, much of the original investment thesis has been left unrealised. The company has improved technology and customer operations, but the cross-selling opportunities that justify premium valuations remain locked out.

Competitive Pressure Rising

Beyond regulatory constraints, Entain has acknowledged rising competitive intensity. STS has begun losing market share as rivals including Betclic and Superbet have increased marketing spend and enhanced product offerings. Rather than match aggressive promotional activity, Entain chose to protect profitability. A defensive posture that signals diminishing confidence in the market’s trajectory.

Croatia has performed considerably better, worth noting. Revenue expanding at a faster pace. Yet even SuperSport’s superior growth hasn’t been enough to keep Entain committed to the region.

A Question of Priorities

The timing and mechanics of this sale reveal where Entain’s strategic focus has shifted. The existing partnership structure with EMMA Capital provided a straightforward exit route without requiring a broader asset sale process. Closing is expected in Q4 2026, after which Entain’s stake will fall below 50 percent and EMMA will gain control.

What emerges is a picture of financial necessity overriding operational logic. Entain is stepping away from two profitable, market leading businesses not because the Central European strategy failed, but because pressures elsewhere in the group have become more pressing. The US joint venture, BetMGM, now commands investor attention and capital allocation. The UK tax crisis demands immediate balance sheet relief.

In that context, CEE becomes the easiest asset to monetize, regardless of its underlying merit.

What the team thinks

Carl Mitchell says:

Philippa’s piece nails the surface puzzle, but I’d argue the real story is about regulatory headwinds and capital allocation efficiency that go beyond balance sheet optics. From my vantage point covering the UK market over the past decade, I’ve seen operators increasingly prioritize jurisdictions where compliance costs and reputational risk are more predictable, and the CEE region has become a minefield on both fronts. Entain’s move is less about abandoning winners and more about freeing up resources and management bandwidth for markets where being a leading operator actually translates to long-term shareholder value without constant regulatory friction.
