Note 29.Employee benefit plans

Defined benefit post-retirement plan

The Group maintains three pension plans: one maintained by SEALSQ Corp covering its employees in Switzerland, one maintained by SEALSQ France SAS and one maintained by IC’Alps SAS, both covering their employees in France.

All plans are considered defined benefit plans and accounted for in accordance with ASC 715 Compensation – Retirement Benefits. This model allocates pension costs over the service period of employees in the plan. The underlying principle is that employees render services ratably over this period, and therefore, the income statement effects of pensions should follow a similar pattern. ASC 715 requires recognition of the funded status or difference between the fair value of plan assets and the projected benefit obligations of the pension plan on the balance sheet, with a corresponding adjustment recorded in the net loss. If the projected benefit obligation exceeds the fair value of the plan assets, then that difference or unfunded status represents the pension liability.

The Group records net service cost as an operating expense and other components of defined benefit plans as a non-operating expense in the statement of comprehensive loss.

The liabilities and annual income or expense of the pension plan are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate and the long-term rate of asset return (based on the market-related value of assets). The fair value of plan assets is determined based on prevailing market prices.

The defined benefit pension plan maintained by SEALSQ France SAS and IC’Alps SAS, and their obligations to employees in terms of retirement benefits, is limited to a lump sum payment based on remuneration and length of service, determined for each employee. The plan is not funded, which means that there are no plan assets.

The liabilities and annual income or expense of the pension plan are determined using methodologies that involve several actuarial assumptions, the most significant of which is the discount rate.

For SEALSQ Corp’s funded plan, the expected long-term rate of return on assets is based on the pension fund’s asset allocation.

All of the assets are held under the collective contract by the plan’s re-insurer company and are invested in a mix of Swiss and International bond and equity securities. In line with ASC 820’s three-tier fair value hierarchy, pension assets belong to the fair value level 2.

As at December 31, 2025 and 2024, the Group’s accumulated benefit obligation amounted to, respectively, USD 2,162,000 and USD 463,381.
