Where the problems are
The income statement is where management tells the story; the balance sheet, the cash flow statement and the notes are where the story is checked. A gambling company can grow revenue and adjusted EBITDA in the same year that it writes down its acquisitions and provides for a regulatory penalty: Entain's 2025 accounts showed revenue up 3% and underlying EBITDA up 7% alongside a £586.8 million impairment, a £53.7 million provision for proceedings brought by AUSTRAC, Australia's anti-money-laundering regulator, and a pre-tax loss of £556.8 million. This lesson is about the parts of the accounts that show trouble before the headline does.
Customer balances and the company's cash
An operator holds customers' money. It appears as cash on the asset side and as a liability (customer balances, player funds) on the other. Two things to check: that the company separates customer cash from its own when it talks about liquidity, and that the cash held matches or exceeds the balances owed. Entain, for example, adds the £197.0 million of cash it held on behalf of customers at the end of 2025 to its net debt when it calculates adjusted net debt. The comparison is not always one to one: DraftKings reported cash reserved for users of $469.4 million against liabilities to users of $935.0 million at 31 December 2025, a liability that includes pending wagers and that, the company says, may be covered by a combination of cash reserved for users, receivables reserved for users and surety bonds, so read the note that explains the cover. What the rules require varies by market. In Britain, remote operators must hold customer funds in a separate client bank account and tell customers whether those funds are protected if the company becomes insolvent, using the Commission's rating system, in which segregation alone is rated "not protected" and only arrangements such as Quistclose accounts, insurance or an independent trust earn a medium or high rating. A company whose own cash is small once customer balances are removed, and whose debt is large, is more fragile than its cash line suggests. Know, too, what the protection covers. Under the British rules, money already staked is no longer customer funds: when BetIndex, the operator of Football Index, collapsed in March 2021, its unstaked customer funds of about £3.2 million sat in a trust account, while open bets valued at £124.3 million at the price customers paid had no such protection.
Leverage
Net debt (borrowings less the company's own cash) divided by adjusted EBITDA is the leverage ratio. Consolidators run high leverage because acquisitions are debt-funded, and lenders set covenants (a maximum ratio) that, if breached, let them demand repayment. Not every facility tests one every quarter: DraftKings' credit agreement applies a maximum net first lien leverage ratio of 4.50 times only to its revolving credit facility, tested only when more than 40% of that facility is in use. Read: the ratio and its trend; the covenant level, if disclosed; the maturity profile (when the debt has to be refinanced); and the interest cost, which at high leverage can consume much of the operating profit. A regulatory shock (a tax rise, an advertising ban) that cuts EBITDA can breach a covenant without any change to the debt, which is why leveraged gambling companies have had difficult years when the rules moved.
Goodwill, intangibles and impairments
Every acquisition leaves goodwill (the premium over the acquired net assets) and intangibles (brands, customer lists, technology, licences) on the balance sheet. Intangibles with a finite useful life are amortised; goodwill, and any intangible judged to have an indefinite life, is not amortised but tested for impairment at least annually, and under IFRS an impairment of goodwill can never be reversed. An impairment is management admitting the acquired business is worth less than the value carried on the balance sheet: it is non-cash, adjusted out of EBITDA, and the single most honest number in a consolidator's accounts. Read the impairment note for which acquisition, why, and whether the assumptions used (growth rates, discount rates, market conditions) look realistic for the rest of the goodwill. Regulation shows up here quickly: Entain took a £487.7 million impairment of its UK goodwill in 2025 after the November 2025 Budget raised Remote Gaming Duty from 21% to 40% from 1 April 2026, cutting the forecast cash flows the goodwill was tested against.
Provisions and contingent liabilities
The provisions note lists money set aside for obligations that exist, will probably have to be paid and can be reliably estimated: regulatory settlements under negotiation, litigation, tax disputes, restructuring. The contingent liabilities note lists possible obligations, or present ones whose payment is not probable or cannot be reliably measured, which are disclosed rather than provided for unless the chance of payment is remote: an investigation, a tax authority's challenge, a claim. In gambling the recurring items are regulatory investigations (AML and responsible gambling findings that become settlements), gaming tax disputes (a tax authority's different view of the base), and, for companies that operated in grey markets, historic liabilities in markets that later regulated. A provision appearing for the first time, or a contingent liability being reclassified as a provision, is news the press release will not headline. Entain's 2025 accounts show the pattern: a provision for the AUSTRAC proceedings of £53.7 million, against nil a year earlier, which its auditor flagged for its high degree of estimation uncertainty.
Working capital and cash conversion
Gambling has favourable working capital: customers deposit before they play, suppliers are paid in arrears, and gaming duty is paid in arrears too: in Britain, Remote Gaming Duty is returned and paid for each three-month accounting period, within 30 days of its end. Cash from operations should therefore run close to or above adjusted EBITDA. Read the cash flow statement: cash from operations, then capital expenditure (technology, studios), then lease payments, interest and tax, to reach free cash flow. Compare with adjusted EBITDA over several periods. Persistent shortfall means the adjustments are real cash (settlements, restructuring every year), or interest and tax are heavy, or, occasionally, revenue is being recognised ahead of cash.
Revenue recognition and the definitions again
Companies choose where in the chain to recognise revenue (GGR or NGR; before or after tax) and how to treat bonuses, jackpot contributions, loyalty points and affiliate costs. Under IFRS a voluntary change in policy is applied retrospectively, restating the comparatives, and is disclosed in the notes; a reader who misses it compares unlike with unlike. The other recognition question is timing: sports bets are settled at the event, so the quarter-end matters for outright markets, and the two main frameworks treat open bets differently: Entain, under IFRS, carries open ante-post positions at fair value and recognises the gains and losses in revenue, while DraftKings, under US GAAP, holds wagered amounts on unsettled outcomes as deferred revenue; supplier revenue share depends on operators' reporting, and platform fees may be recognised over a contract term.
Related parties and the founder
Founder-led and family-controlled operators (common in gambling) have related-party notes worth reading: loans to and from the founder, property leased from a founder's company, services bought from associated companies, dual-class share structures that give control disproportionate to economic ownership. At DraftKings, for example, the chief executive holds all the Class B shares, which carry 10 votes each, and about 89% of the voting power. None is improper by itself; all are disclosed for a reason.
Regulatory disclosures
The business, risk factor and legal sections of an annual report or 10-K set out the licences and markets the company depends on, the most significant risks it faces (Item 1A of a 10-K) and significant pending legal proceedings (Item 3), including investigations and pending legal changes. Read them for changes from the prior year: a new investigation, a market moved from "regulated" to "under review", a licence renewal flagged as uncertain. Companies word these carefully; a change in wording is a change in position.
The failure patterns
The gambling companies that have failed or come under strain tend to show patterns visible in the accounts beforehand: high leverage against EBITDA exposed to a regulatory shock; customer balances counted as liquidity; goodwill from acquisitions at peak prices; provisions for regulatory matters growing; grey-market revenue undisclosed until it was lost; cash conversion deteriorating while adjusted EBITDA held up. None of these requires inside knowledge; all appear in the accounts and notes. The reader's advantage is reading them.
The final lesson puts the pieces together: comparing companies that report differently and reading what the sector as a whole is saying.
