The operator's story in five numbers
An operator's results answer five questions, and a reader who finds the five numbers has most of the picture: how many customers, how much each was worth, what it cost to get and keep them, what the state took, and what was left. This lesson walks through an operator's announcement in that order, with the checks that turn the company's numbers into an independent view.
Customers
Start with actives, by the company's definition, and the trend. Definitions differ: Flutter counts average monthly players who have had a bet settled or contributed to a rake or tournament fee, DraftKings counts monthly unique payers, and Betsson counts customers who have played in the past three months. Then read the trend: growing, flat or shrinking, year on year and sequentially, by market where reported. Then first-time depositors, which tell you whether growth is new customers or a retained base; Rush Street Interactive, for example, reported record first-time depositors in the first quarter of 2026 alongside its marketing spend. The ratio of FTDs to actives says how much of the base is new; a base that is mostly new is expensive and fragile, and one that is mostly old is cheap and stable.
Checks: has the definition of active changed (a footnote will say)? Are actives reported by market, and is growth in mature markets or launch markets? Has a market exit moved the total? Flutter's group players fell 11% year on year in the second quarter of 2026, and the company attributed 17 percentage points of that to its exit from real-money gaming in India after a change in Indian law. Does the company report retention or cohort data (few do; those that do are worth more attention)?
Revenue and its quality
Revenue by product (sports, casino, poker, other) and by market, in the company's revenue definition. Then the quality questions:
Hold. For sports, the reported margin against the company's normalised margin. A quarter with hold two points below normal has been unlucky, and the company will say so; the reader's job is to accept it once and not every quarter. The best disclosures split the margin into its parts: Flutter's US sportsbook reported a structural revenue margin of 14.2% in 2025, sports results 60 basis points unfavourable (after 120 unfavourable in 2024) and a rise in player incentive spend, which netted to a sportsbook net revenue margin of 8.6%. Persistent "bad luck" is pricing too keenly or a product mix shift.
Product mix. Casino revenue is steadier than sports, because it does not depend on sports results; Flutter describes same game parlays as higher margin bet types and credits rising parlay penetration with expanding its structural margin, which is why operators report parlay penetration as a margin driver. A rising casino share in a sports-led operator is a margin story; a falling one is a warning.
Market mix. Revenue from regulated markets versus unregulated or grey, where the company discloses it. Grey-market revenue is at risk of regulation, enforcement and, for the company's own regulators, suitability questions; investors discount it and so should readers. Remember that regulated revenue usually carries more tax and compliance cost: Betsson, whose share of revenue from locally regulated markets rose to 73% in the first quarter of 2026 from 59%, named that shift as a key reason for lower profitability.
Currency. Constant-currency growth versus reported, for multi-market operators. Flutter, for example, reported that favourable exchange-rate movements added 2% to its International revenue in 2025.
Acquisition and marketing
The largest discretionary cost. Read marketing spend in absolute terms, as a share of revenue, and per first-time depositor (the crude acquisition cost), all against the prior year. The pattern to look for: marketing as a share of revenue falling while actives grow means a maturing base; rising while actives are flat means a market getting more competitive or an operator losing efficiency. Where a company guides on marketing, as a sum or a share of revenue, check the guidance against the outcome. Check too what the company counts as marketing: Rush Street Interactive reported adjusted sales and marketing of 12.5% of revenue in the first quarter of 2026, while Betsson reports marketing excluding affiliate and partner commissions, which it books in cost of services instead.
Bonuses are marketing in disguise. Where the company reports bonus cost or the gap between GGR and NGR, watch it: a rising bonus share means the company is buying revenue.
Tax and the cost of sales
Gaming tax as a share of GGR, by market where possible. A rise says a tax change has landed or the mix has shifted toward higher-tax markets; DraftKings, for example, cited higher gaming tax rates in certain jurisdictions in its 2025 cost of revenue. Platform and content costs as a share of revenue: rising can mean more third-party content (live casino) or worse supplier terms. Payment costs move too, with deposit volumes and payment mix: in 2025 DraftKings reported lower payment processing fees as a share of revenue, while Betsson reported higher payment provider fees in the first quarter of 2026.
What is left
Adjusted EBITDA and its margin on revenue, and then the reconciliation to statutory profit: what was adjusted out, and is it recurring? Regulatory settlements appear here; so do acquisition costs at consolidators. Then depreciation and amortisation (large where acquired intangibles are being amortised), interest (large where the group is leveraged), and tax. Then net income, which for acquisitive or leveraged operators is often a fraction of adjusted EBITDA, and sometimes a loss: in the second quarter of 2026 Flutter reported adjusted EBITDA of $508 million and a net loss of $296 million.
Then free cash flow. An operator's cash conversion should be high: customers deposit before they play, capital expenditure is modest, and working capital is favourable. Because customer deposits pass through the operator's cash, check whether free cash flow includes them; Flutter reports a second free cash flow measure that excludes player funds, and in the second quarter of 2026 it was $125 million against $189 million on the headline measure. If free cash flow is far below adjusted EBITDA, something adjusted out was real cash, or interest and tax are eating the profit.
Guidance and the outlook
Operators guide on revenue, adjusted EBITDA and sometimes marketing for the year, and many restate or update it with each quarter's results, as DraftKings did when it maintained its 2026 revenue and adjusted EBITDA ranges in August 2026. Compare the new guidance with the old: a cut is the news, whatever the quarter's numbers. In August 2026 Flutter cut its 2026 US guidance midpoints by $395 million of revenue and $210 million of adjusted EBITDA. Read the assumptions: Flutter's guidance is given on the basis that sports results are in line with its expected margin for the rest of the year, at stated exchange rates, and with a consistent regulatory and tax framework. The assumptions are where the risk is.
The US operator variant
US operators report with some specifics: revenue after promotional credits (DraftKings records unredeemed incentive awards as a reduction to revenue, so "revenue" is closer to NGR), state-by-state launches that distort comparisons, market share by state from regulator data (New Jersey's Division of Gaming Enforcement, for example, publishes online gaming win by brand each month), "contribution profit" (revenue less variable costs, before fixed costs; definitions vary, and DraftKings, for example, describes its marketing spend as variable) as a bridge toward profitability, and a path-to-profitability narrative that lasted years: DraftKings, which says it reaches adjusted EBITDA profitability when total contribution profit exceeds its fixed costs, reported net losses of $802 million in 2023 and $507 million in 2024 before net income of $3.7 million in 2025. The reader's checks: share in the mature states (New Jersey, Pennsylvania, Michigan) against the launch states; casino revenue as a share of total (online casino is legal in far fewer states: DraftKings offers it in 5 states against sports betting in 27, and its revenue does not depend on sports results); and the gap between contribution profit and adjusted EBITDA, which is the fixed cost base.
Red flags in operator results
- Actives flat and revenue rising: growth from fewer, larger customers, which is a responsible gambling and concentration risk.
- Hold "below normal" for several quarters running.
- Marketing rising as a share of revenue with actives flat.
- Revenue definition or active definition changed without restated comparatives.
- Adjusted items recurring every year.
- Free cash flow persistently below adjusted EBITDA.
- Grey-market share not disclosed by a company that plainly has one.
- A provision for regulatory matters appearing for the first time.
- Guidance cut with the explanation "timing".
None of these proves trouble on its own, but each is a question to put to the company, and several together deserve a closer read of the next results. The next lesson turns to suppliers, whose results tell a different story.
