Where deals are won and lost
The price was set on a model of the combined business. Integration is the process of making the combined business exist, and it is where the synergy assumptions either become cash or become the write-down the acquirer announces two years later. Acquisitions can destroy a great deal of value for the buyer's own shareholders: one widely cited study found that acquiring-firm shareholders lost 12 cents at announcement for every dollar spent on acquisitions between 1998 and 2001, although most of that aggregate loss came from a small number of acquisitions by firms with extremely high valuations. Gambling has its own write-downs, and the difference between the deals that worked and the ones that did not is more often execution than price.
The first hundred days
The integration plan should have been built before closing, with a clean team where competition law required it, and should be executable from day one. Competition authorities expect competitively sensitive information shared for diligence and integration planning to be confined to clean teams that exclude anyone responsible for pricing or strategy, and the parties must not start running the businesses together before closing. Its first phase has a small number of jobs:
Control. The buyer's finance, compliance and risk functions take over the target's reporting lines immediately. Player fund reconciliation, AML monitoring and regulatory reporting continue without a gap; a regulator will not accept "we had just closed" as an explanation for a missed return. In Britain, for example, every operating licensee must submit a regulatory return within 28 days of the end of each quarter.
Decisions announced. Who runs what, which brands survive, which platform is the destination, which offices close. Uncertainty drains a target faster than any decision does. The plan should name the decisions that will be made in the first month and make them.
Retention executed. The retention packages agreed at signing are confirmed; the people the buyer wants to keep are told so individually and given a role; the people who are leaving are told so with dignity and a timetable.
Customers reassured. Nothing changes for them yet. A change to a customer's terms, bonus policy or brand in the first weeks is read as a downgrade and drives churn.
Quick synergies taken. Duplicate third-party contracts, overlapping marketing, redundant office space. The cost synergies that need no migration are the credibility deposit with the board and the market.
Platform migration
In a consolidation deal, the largest synergy and the largest risk are the same event: moving the target's customers onto the acquirer's platform. The synergy is one technology stack, one content roadmap, one set of integrations. The timetable can be long: evoke, which acquired William Hill in 2022, said in its 2025 results that moving Mr Green onto its in-house platform had cut the royalties it paid to third parties, and that the remaining elements of the William Hill platform integration should be substantially complete by the end of 2026. The risk is that customers who are migrated leave.
Migration losses are real, and a buyer that tracks customers and revenue wave by wave can measure them. The causes are predictable: a product that is different from the one the customer chose, lost account history and favourites, forced re-verification, a bonus balance that did not carry, an app that had to be reinstalled, and a period of instability while the new platform absorbs the load.
The disciplines that reduce the loss:
- Migrate in waves, by market or by segment, and measure churn in each wave before the next.
- Carry everything: balances, bonuses, loyalty status, favourites, limits and self-exclusions. The last two are regulatory requirements, not conveniences: in Britain, once the businesses are in one group, a remote licensee must take all reasonable steps to ensure that a self-exclusion covers, and financial limits can be applied across, the accounts a customer holds with group companies (social responsibility code 3.9.1).
- Do not re-verify customers whose verification is still valid where the rules allow existing checks to be relied on: in Britain, the Money Laundering Regulations 2017 allow a firm to rely on customer due diligence carried out by another regulated firm, including one in the same group, although the firm relying on it remains liable for any failure. Where they do not, plan the re-verification rather than springing it on customers.
- Keep the old brand and front end where the customers chose it, running on the new platform underneath. Brand consolidation is a separate decision and it should come later, if at all.
- Over-communicate, with the customer's own account manager where they have one.
A buyer may conclude that the migration loss exceeds the platform synergy and run two platforms indefinitely. That is a legitimate answer, and it should be reached from the numbers rather than from pride in the buyer's own technology.
Brand strategy
The buyer has two brands and one customer base per market. The options are to keep both, retire one, or merge them under a new identity, and the answer differs by market. Where the two brands appeal to different segments (a recreational casino brand and a sharp sportsbook brand), keeping both is usually right. Where they compete for the same customer, one should go, but slowly: brands carry search equity, affiliate relationships and customer habit that a fast retirement destroys.
The share of marketing spend between brands is where the synergy is realised in practice. Two brands each spending to acquire the same customer are bidding against each other in the same auctions; the combined company stops that immediately, and the saving is real.
Culture and people
Gambling companies have distinctive cultures shaped by their founders, their home markets and their product. Merging a Nordic sportsbook with a Mediterranean casino group, or a founder-led business with a listed corporate, produces friction that the plan should expect. The specific risks:
- Trading and product teams from the acquired company who believe their approach was better and are now reporting to people who chose the other one.
- Compliance cultures at different levels of maturity, where the target's staff experience the acquirer's controls as bureaucracy and the acquirer's staff experience the target's habits as risk.
- Loss of the informal knowledge that made the target work: who the key affiliates are, which payment processor is unreliable in which market, which regulator responds to which approach.
The people who hold that knowledge are identifiable in diligence and should be retained through the integration, whatever the org chart says about their level.
Tracking the value
The board approved the deal on a synergy number. It should see, every quarter, the synergies realised against plan, split into cost and revenue, the one-off costs of achieving them, the dis-synergies (customers lost, staff left, contracts terminated), and the target's underlying performance against the diligence case. This is the accountability mechanism that makes the next deal's synergy case credible, and it is also how a board finds out early that a deal is not working.
The market tracks the same thing from outside. Acquirers reporting under IFRS must disclose the revenue and profit or loss the acquired business contributed from the acquisition date to the end of the reporting period (IFRS 3, paragraph B64(q)), and the share price reacts to whether the synergy timetable is being met. The International Accounting Standards Board has proposed requiring more: its March 2024 exposure draft would improve the information companies disclose about the performance of business combinations, and in 2026 the Board was still redeliberating it. An acquirer that under-delivers on integration loses the credibility to do the next deal at a price the market will accept, which for a consolidator is the business model.
When it did not work
Some deals fail. The signs: the synergy plan slips by more than a quarter, migration churn exceeds the modelled range, key people leave in a cluster, a regulatory condition imposed at approval turns out to cost more than expected. The honest response is an impairment, a public reset of the plan, and a decision about whether the asset is worth continuing to invest in or should be sold, sometimes to a buyer better suited to it. The dishonest response is to keep reporting the original plan and hope, and it is tempting, because an impairment is an admission that the price was wrong. Accounting rules limit how long that can last: under IFRS, goodwill must be tested for impairment at least annually, and whenever there is an indication that it may be impaired, and a goodwill impairment can never be reversed (IAS 36, paragraphs 90 and 124). The cause is not always the integration: evoke reported £440.3m of impairment charges on its UK online and retail businesses for 2025, citing the increase in UK online gambling duties announced in November 2025 and difficult high street conditions.
The course in one paragraph
A gambling deal is a bet on customers, made under a regulator's supervision, paid for on a synergy case that only integration can deliver. Understand why the deal is happening, because the rationale sets everything else. Value the revenue by its regulatory quality and the customers by their cohorts, not by a multiple. Diligence the licence, the player funds, the tax history and the compliance practice as hard as the earnings. Structure the risk you found to the party who can bear it. Run the regulatory process as a project with a clock. Then integrate deliberately, migrate carefully, keep the people who know things, and report the truth about whether the value arrived.
