3.5 Intangible assets

Based on the impairment tests performed, there was no need for the recognition of any impairment of goodwill for the 2024/25 and 2023/24 financial years.

The cash flow projections used for impairment testing, were based on the most recent business plan. The business plan was projected over a five year period.

Hearing instruments

As of March 31, 2025, the carrying amount of goodwill, expressed in various currencies, amounted to an equivalent of CHF 2,123.6 million (prior year CHF 2,128.9 million) and for intangible assets with indefinite useful lives to CHF 98.2 million (prior year: CHF 100.1 million). The intangible assets with indefinite useful lives relates to the Sennheiser brand name that was acquired as part of the acquisition of the Consumer Division from Sennheiser in financial year 2021/22. It has been determined to have an indefinite useful life as there is no intention to abandon the brand name. It has existed for many years and the Group has the ability to maintain its brand value for an indefinite period of time. Thus, the brand is not amortized but is assessed for impairment annually.

Cash flows beyond the projection period were extrapolated with a long-term growth rate of 2.1% (prior year 2.1%) which represents the projected inflation rate. For the calculation, a pre-tax weighted average discount rate of 9.6% (prior year 11.2%) was used. The Group performed a sensitivity analysis, which shows that changes to the main input parameters (increase of discount rate +1%, or long-term growth rate –1%) would not result in an impairment of goodwill.

Cochlear implants

As of March 31, 2025, the carrying amount of the goodwill, expressed in various currencies, amounted to an equivalent of CHF 284.0 million (prior year CHF 290.7 million).

Cash flows beyond the projection period were extrapolated with a long-term growth rate of 2.1% (prior year 2.2%) which represents the projected inflation rate. For the calculation, a pre-tax weighted average discount rate of 9.0% (prior year 11.8%) was used. The Group performed a sensitivity analysis, which shows that changes to the main input parameters (increase of discount rate +1%, or long-term growth rate –1%) would not result in an impairment of goodwill.

The capitalized development costs are reviewed on a regular basis. In the current financial year this review did not lead to any valuation adjustments. The capitalized development costs are included in the reportable segment “cochlear implants” disclosed in Note 2.2.

Accounting policies

Goodwill

Goodwill is recognized for any difference between the cost of the business combination and the net fair value of the identifiable assets, liabilities, and contingent liabilities (refer to accounting policies in Note 6.1). Goodwill is not amortized, but is assessed for impairment annually, or more frequently if events or changes in circumstances indicate that its value might be impaired. For the purpose of impairment testing, goodwill is allocated to cash-generating units that are expected to benefit from the synergies of the corresponding business combination. For the Group, a meaningful goodwill allocation can only be done at the level of the segments, hearing instruments and cochlear implants. This also reflects the level that the goodwill is monitored by management. To assess for impairment, the recoverable amount of cash-generating units are compared to the carrying amount. The carrying amount is determined based on a value-in-use calculation considering a five-year cash flow projection period and extrapolated using a terminal value for cash flows beyond the planning period. The cash flow projections are estimated on the basis of the strategic plan approved by the Board of Directors. Future cash flows are discounted with the Weighted Average Cost of Capital (WACC).

Intangibles, excluding goodwill

Purchased intangible assets such as software, licenses and patents are measured at cost less accumulated amortization (applying the straight-line method) and any impairment in value. Software is amortized over a useful lifetime of 3 – 5 years. Intangibles relating to acquisitions of subsidiaries (excluding goodwill) consist generally of technology, client relationships, customer lists, and brand names, and are amortized over a period of 3 – 20 years (except for the Sennheiser brand name as disclosed above). Other intangible assets are generally amortized over a period of 3 – 10 years. For capitalized development costs in the cochlear implants segment, amortization starts when the capitalized asset is ready for use, which is generally after receipt of approval from regulatory bodies. These assets are amortized over the estimated useful lifetime of 2 – 7 years applying the straight-line method. For in-process capitalized development costs, these capitalized costs are tested annually for impairment. Except for goodwill and the Sennheiser brand, the Sonova Group has no intangible assets with an indefinite useful life.

Intangible assets with indefinite useful lives are not amortized, but are tested for impairment annually at the cash-generating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable.

Research costs are expensed as incurred. Development costs are capitalized only if the identifiable asset is commercially and technically feasible, can be completed, its costs can be measured reliably and will generate probable future economic benefits. Group expenditures, which fulfill these criteria are limited to the development of tooling and equipment as well as costs related to the development of cochlear implants. All other development costs are expensed as incurred. In addition to the internal costs (direct personnel and other operating costs, depreciation on research and development equipment and allocated occupancy costs), total costs also include externally contracted development work. Such capitalized intangibles are recognized at cost less accumulated amortization and impairment losses.

Accounting judgements and estimates

Goodwill and intangible assets with indefinite useful lives

The recoverable amount of cash-generating units is measured on the basis of value-in-use calculations and as such is significantly impacted by the projected cash flows, the discount rate, and the long-term growth rate, which are subject to management judgment. Actual cash flows as well as other input parameters could vary significantly from these estimates.

Capitalized development costs

The Group capitalizes costs relating to the development of cochlear implants. The capitalized development costs are reviewed on a regular basis as a matter of a standard systematic procedure. In determining the commercial as well as the technical feasibility, management judgment may be required.
