Financial results

Monetary columns are in M USD, one decimal; scale (K/M/B/T) keeps values readable. For the period (default) shows P&L and cash flow for that row’s reporting window: quarterly amounts when the feed uses quarter-duration facts (typical US 10-Q revenue and income), quarterly cash flows after stripping YTD where only cumulative tags exist, and an implied Q4 on 31 Dec FY rows (P&L: FY minus Q1–Q3; operating / investing cash flow: FY 12m minus 9M YTD to 30 Sep when sourced from SEC builder evidence) so they match 10-Q scale. Some issuers still use cumulative YTD minus the prior row in the same calendar year. As reported shows values stored on each row (e.g. full-year on FY). Balance sheet is always as reported. Source JSON may use millions etc.; conversion uses amounts_unit per row.

Profit and cash

Profit is cash-backed
In a typical year of 2021–2025 operating cash flow came to 1.42x of reported net profit; after capex, 1.28x. Loss years (2022) are left out of the ratio.
year20212022202320242025
cash flow / profit11.41x—0.59x1.28x1.56x
accruals, % of assets-15.5%-24.2%11.0%-3.8%-8.5%
Last twelve months (to 2026-09-30): 0.99x of profit came back as operating cash flow.
net debt / EBITDA -0.6x · EBIT covers interest 185.9x · capex 1.4x of depreciation · share count -1.2% a year
Read from the reported annual statements: cash flow / profit is the median of the yearly operating cash flow over net profit for the years shown; accruals are (profit − operating cash flow) / assets, the classic gap between what was booked and what was collected. A gap can be growth in working capital, capitalised costs, revaluations or profit from associates — the panel points at it, the statements explain it. Not investment advice.

Fundamental value creation

Value the company creates per year, as a % of market cap

Value created per year: +16.6%

How this was calculated
1. EBITDA growth (latest quarter YoY, annualised)
[EBITDA latest qtr − EBITDA year-ago qtr] × annualisation X (2026-09-30 vs 2025-09-30)
= (87 − 66) × 3.57
73
2. Current EV/EBITDA (LTM)
(Market cap + Net debt) ÷ EBITDA (LTM)
= (8 878 + -90) ÷ 309
28.4x
3. Target multiple
(Current EV/EBITDA + 12) ÷ 2
= (28.4 + 12) ÷ 2
20.2x
4. Cash flow (balance method, LTM)
Net-debt reduction + dividends + buybacks − equity issuance
= 38 + 0 + 3 − 0
40
4b. Share dilution (at market, LTM)
Share-count growth over the year × Market cap
= 0.4% × 8 878
−33
5. Value created per year
(EBITDA growth × Target multiple + Cash flow − Dilution) ÷ Market cap
= (73 × 20.2 + 40 − 33) ÷ 8 878
+16.6%

Amounts in millions of the reporting currency. EBITDA growth is the latest quarter vs the same quarter a year ago, annualised.

Caveats:

  • share-count dilution 0.4%/yr (valued at market: -33)

Revenue growth & acceleration

Growth accelerating ▲
Last-year revenue growth +27% vs +21% the year before — a +6.4 pp move. 3-year CAGR +16%.
revenue growth by year: 2023 +1% · 2024 +21% · 2025 +27%
The growth-acceleration signal behind the GARP+acceleration strategy — it favours companies whose revenue growth is speeding up and flags those slowing down (the second derivative of growth).

This companyUS8.929.2x

Group median 24.6x; this company 29.2x — a 19% premium.

Group average 23.4x; against the average this company is at a 25% premium.

At the adjusted group median the market cap would be -16% versus today.

The gap and the implied upside are measured against the median: one richly priced peer moves an average, not a median. The market adjustment uses our coverage medians (US 19.2x, Russia 3.8x, South Africa 5.4x, Kazakhstan 6.3x, India 18.6x, Indonesia 4.7x); it is about where a name is listed, not what it does. Peer multiples come from the nightly rebuild of 2026-11-05; the company's own is live.
