Defined benefit plans

Sonova Groupʼs retirement plans include defined benefit pension plans in Switzerland, Austria, Belgium, Canada, France, Germany and Israel. These plans are both funded and unfunded and governed by local regulations using independent actuarial valuations according to IAS 19. Sonova Groupʼs major defined benefit plan is located in Switzerland, which in total accounts for CHF 611.9 million or 97.9% (previous year CHF 567.1 million or 96.7%) of Sonovaʼs defined benefit obligation.

Pension plans in Switzerland

The current pension arrangement for employees in Switzerland is made through a plan governed by the Swiss Federal Occupational Old Age, Survivors and Disability Pension Act (BVG). The plan of Sonovaʼs Swiss companies is administered by a separate legal foundation, which is funded by regular employer and employee contributions as defined in the pension fund rules. The Swiss pension plan contains a cash balance benefit which is, in essence, contribution-based with certain minimum guarantees. Due to these minimum guarantees, the Swiss plan is treated as a defined benefit plan for the purposes of these consolidated financial statements, although it has many of the characteristics of a defined contribution plan. The plan is invested in a diversified range of assets in accordance with the investment strategy and the common criteria of asset and liability management. A potential under-funding may be remedied by various measures such as increasing employer and employee contributions or reducing prospective benefits. Above a set insured salary, the savings capital will be split into pension-accumulating and capital-accumulating savings capital. The pension-accumulating savings capital will generate a life-long retirement pension upon retirement. The insured person may request a lump sum settlement in lieu of the retirement pension or a part thereof. The capital-accumulating savings capital will generate a one-off capital payment upon retirement. An annuity rate of 5.4% to the individual accumulated retirement savings capital was applied for the financial years 2025/26 and 2024/25.

As of 31 March 2026, 1,328 employees (previous year 1,460 employees) and 207 beneficiaries (previous year 192 beneficiaries) are insured under the Swiss plan. The defined benefit obligation has a duration of 16.0 years (previous year 16.4 years).

Defined contribution plans

Several of the Groupʼs entities have a defined contribution plan. The employerʼs contributions amounted to CHF 30.0 million (thereof CHF 1.6 million related to discontinued operations) in the year ended 31 March 2026 (previous year CHF 31.0 million, thereof CHF 1.7 million related to discontinued operations) and are recognized directly in the income statement.

Accounting policies

Most employees are covered by post-employment plans sponsored by corresponding Group companies in the Sonova Group. Such plans are mainly defined contribution plans (future benefits are determined by reference to the amount of contributions paid) and are generally administered by autonomous pension funds or independent insurance companies. These pension plans are financed through employer and employee contributions. The Groupʼs contributions to defined contribution plans are charged to the income statement in the year to which they relate.

The Group also has several defined benefit pension plans, both funded and unfunded. Accounting and reporting of these plans are based on annual actuarial valuations. Defined benefit obligations and service costs are assessed using the projected unit credit method, with the cost of providing pensions charged to the income statement so as to spread the regular cost over the service lives of employees participating in these plans. The pension obligation is measured as the present value of the estimated future outflows using interest rates of high quality corporate bonds, which have terms to maturity approximating the terms of the related liability. Service costs from defined benefit plans are charged to the appropriate income statement heading within the operating results.

A single net interest component is calculated by applying the discount rate to the net defined benefit asset or liability. The net interest component is recognized in the income statement in the financial result.

Actuarial gains and losses, resulting from changes in actuarial assumptions and differences between assumptions and actual experiences, are recognized in the period in which they occur in “Other comprehensive income” in equity.

Accounting judgements and estimates

The Sonova Group has various employee benefit plans. Most of its salaried employees are covered by these plans, of which some are defined benefit plans. The present value of the defined benefit obligations at the end of the 2025/26 financial year amounts to CHF 624.9 million (previous year CHF 586.3 million). This includes CHF 611.9 million (previous year CHF 567.1 million) from the Swiss pension plan. With such plans, actuarial assumptions are made for the purpose of estimating future developments, including estimates and assumptions relating to discount rates, and future wage as well as pension trends. Actuaries also use statistical data such as mortality tables and staff turnover rates with a view to determining employee benefit obligations. If these factors change due to a change in economic or market conditions, the subsequent results could deviate considerably from the actuarial reports and calculations. In the medium term, such deviations could have an impact on the equity.
