Other information

Measurement of the Group’s defined benefit retirement obligation is sensitive to changes in certain key assumptions. The sensitivity analysis below shows how a reasonably possible increase or decrease in a particular assumption would, in isolation, result in an increase or decrease in the present value of the defined benefit obligation as at 31 March 2024. Rate of inflation Rate of increase in salaries Discount rate Life expectancy Decrease by 0.5% Increase by 0.5% Decrease by 0.5% Increase by 0.5% Decrease by 0.5% Increase by 0.5% Decrease by 1 year Increase by 1 year

1 The sensitivity analysis may not be representative of an actual change in the defined benefit obligation as it is unlikely that changes in assumptions would occur in isolation of one another. In presenting this sensitivity analysis, the change in the present value of the defined benefit obligation has been calculated on the same basis as prior years using the projected unit credit method at the end of the year, which is the same as that applied in calculating the defined benefit obligation liability recognised in the statement of financial position. The rate of inflation assumption sensitivity factors in the impact of changes to all assumptions relating to inflation including the rate of increase in salaries, pension increases and deferred revaluations.

26. Share-based payments The Group has a number of share plans used to award shares to Executive Directors and employees as part of their remuneration package. A charge is recognised over the vesting period in the consolidated income statement to record the cost of these, based on the fair value of the award on the grant date. Accounting policies The Group issues equity-settled share-based awards to certain employees. Equity-settled share-based awards are measured at fair value (excluding the effect of non-market-based vesting conditions) at the date of grant. The fair value determined at the grant date of the equity-settled share- based award is expensed on a straight-line basis over the vesting period, based on the Group’s estimate of the shares that will eventually vest and adjusted for the effect of non-market-based vesting conditions. A corresponding increase in additional paid-in capital is also recognised. Some share awards have an attached market condition, based on total shareholder return (‘TSR’), which is taken into account when calculating the fair value of the share awards. The valuation for the TSR is based on Vodafone’s ranking within the same group of companies, where possible, over the past five years. The fair value of awards of non-vested shares is a calculation of the closing price of the Company’s shares on the day prior to the grant date, adjusted for the present value of the delay in receiving dividends where appropriate. The maximum aggregate number of ordinary shares which may be issued in respect of share options or share plans will not (without shareholder approval) exceed: − 10% of the ordinary share capital of the Company in issue immediately prior to the date of grant, when aggregated with the total number of ordinary shares which have been allocated in the preceding ten year period under all plans; and − 5% of the ordinary share capital of the Company in issue immediately prior to the date of grant, when aggregated with the total number of ordinary shares which have been allocated in the preceding ten year period under all plans, other than any plans which are operated on an all-employee basis. Share options Vodafone Sharesave Plan Under the Vodafone Sharesave Plan UK staff may acquire shares in the Company through monthly savings of up to £375 over a three and/or five year period. The savings may then be used to purchase shares at the option price, which is set at the beginning of the invitation period at a discount of up to 20% to the then prevailing market price of the Company’s shares. Share plans Vodafone Group executive plans Under the Vodafone Global Incentive Plan awards of shares are granted to Directors and certain employees. The release of these shares is conditional upon continued employment and for some awards achievement of certain performance targets measured over a three year period.
