EBITDA bridge, FY2022 → FY2023
What moved EBITDA between the two years: the change in revenue, less the change in reported operating expenses. The costs are one net figure; no split by type is held, so none is shown.
| Step | FY2022 | FY2023 | Effect on EBITDA | Status |
|---|---|---|---|---|
| FY2022 EBITDA | $1,150.0m | $1,150.0m | As charted | |
| Revenue | $3,720.0m | $4,491.0m | +$771.0m | Reported |
| Operating expenses (reported) | $2,570.0m | $2,769.0m | −$199.0m | Reported |
| FY2023 EBITDA | $1,722.0m | $1,722.0m | As charted |
$1,150.0m +$771.0m −$199.0m = $1,722.0m, which equals FY2023 EBITDA of $1,722.0m. EBITDA is the figure stored from each statement; companies that headline an adjusted measure (EBITDAF, underlying EBITDA) can report a different number.

Both years passed the same checks. Margins are shares of revenue; their change is in percentage points. n/m = not meaningful (prior-year figure at or below zero). Each year holds the figures from its own annual report; restated comparatives are not applied.
Margins over time
EBITDA, EBIT and net profit as a share of revenue for each year whose figures passed the checks (8 of 9 years from FY2017). The shaded line is the median of 3 other listed Communication Services operating companies, using each one’s same financial year where it passed the checks; the number of companies in each median is in the table. Gaps are years that were not charted.
SPK peer median below the axis: year not charted (reason in the table). All panels share one scale.

Peer medians use only peer-years that passed the same checks; a median of fewer than two companies is not shown. Years are grouped by financial-year label, and year-end months differ between companies.
Not yet available: where the cash goes (operating cash flow to capex, dividends and debt) and underlying versus reported earnings. The figures they need are not yet validated.
Years not charted
These years are on file but their figures did not pass the checks, so no chart is drawn for them.
