Note 11 — Employee Benefit Plans

Defined Benefit Plan – Switzerland

The Company maintains a passive pension plan (the “Swiss Plan”) covering employees of STAAR AG, which is accounted for as a defined benefit plan.

In Switzerland employers are required to provide a minimum pension plan for their staff. Contributions of both the employees and employer finance the Swiss Plan. The amount of the contributions is defined by the plan regulations and cannot be decreased without amending the plan regulations. It is required that the employer contribute an amount equal to or greater than the employee contribution.

The following table shows the changes in the benefit obligation and plan assets and the Swiss Plan’s funded status (in thousands):

Net periodic pension cost and projected and accumulated pension obligation for the Company’s Swiss Plan were calculated using the following assumptions:

	2025			2024
Discount rate		1.3	%		1.0	%
Salary increases		2.5	%		2.5	%
Expected return on plan assets		3.0	%		3.0	%
Expected average remaining working lives in years		9.7			9.8

The discount rates are based on an assumed duration of the pension obligations and estimated using the rates of returns for AAA and AA-rated Swiss and foreign CHF-denominated corporate bonds listed on the SIX Swiss Exchange. The salary increase rate was based on the Company’s best estimate of future increases over time. The expected long-term rate of return on plan assets is based on the expected asset allocation and assumptions concerning long-term interest rates, inflation rates, and risk premiums for equities above the risk-free rates of return. These assumptions take into consideration historical long-term rates of return for relevant asset categories.

Under Swiss law, pension funds are legally independent from the employer and all the contributions are invested with regulated entities. The Company has a contract with Allianz Suisse Life Insurance Company’s BVG Collective Foundation (the “Foundation”) to manage its Swiss pension fund. Multiple employers contract with the Foundation to manage the employers’ respective pension plans. The Foundation manages the pension plans of its contracted employers as a collective entity. The investment strategy is determined by the Foundation and applies to all members of the collective Foundation. There are no separate financial statements for each employer contract. The pension plan assets of all the employers that contract with the Foundation are comingled. They are considered multiple-employer plans and therefore accounted for as single-employer plans.

Note 11 — Employee Benefit Plans (Continued)

Defined Benefit Plan – Switzerland (Continued)

As there are no separate financial statements for each employer contract, there are no individual investments that can be directly attributed to the Company’s pension plan assets. However, the funds contributed by an employer are specifically earmarked for its employees and the total assets of the plan allocable to Company’s employees are separately tracked by the Foundation. The lack of visibility into the specific investments of the plan assets and how they are valued is a significant unobservable input, therefore, the Company considers the plan assets collectively to be Level 3 assets under the fair value hierarchy.

The table below sets forth the fair value of Plan assets at January 2, 2026 and December 27, 2024, and the related activity in years ended 2025 and 2024 (in thousands):

	Insurance Contracts (Level 3)
Ending balance at December 29, 2023	$	17,381
Actual return on plan assets		(942	)
Purchases, sales, and settlement		1,251
Ending balance at December 27, 2024	$	17,690
Actual return on plan assets		2,762
Purchases, sales, and settlement		1,001
Ending balance at January 2, 2026	$	21,453

During fiscal year 2026, the Company expects to make cash contributions totaling approximately $1,387,000 to the Swiss Plan.

The estimated future benefit payments for the Swiss Plan are as follows (in thousands):

Year Ended	Amount
2026	$	93
2027		122
2028		3,976
2029		641

Defined Benefit Plan – Japan

STAAR Japan maintains a noncontributory defined benefit pension plan (“Japan Plan”) substantially covering all the employees of STAAR Japan. Benefits under the Japan Plan are earned, vested, and accumulated based on a point-system, primarily based on the combination of years of service, actual and expected future grades (management or non-management) and actual and future zone (performance) levels of the employees. Each point earned is worth a fixed monetary value, 1,000 Yen per point, regardless of the level grade or zone of the employee. Gross benefits are calculated based on the cumulative number of points earned over the service period multiplied by 1,000 Yen. The mandatory retirement age limit is 60 years old.

STAAR Japan administers the pension plan and funds the obligations of the Japan Plan from STAAR Japan’s operating cash flows. STAAR Japan is not required, and does not intend, to provide contributions to the Plan to meet benefit obligations and therefore does not have any plan assets. Benefit payments are made to beneficiaries as they become due.

Defined Contribution Plan

The Company has a 401(k) profit sharing plan (“401(k) Plan”) for the benefit of qualified employees in the U.S. During the year ended January 2, 2026, employees who participate may elect to make salary deferral contributions to the 401(k) Plan up to $23,500 of the employees’ eligible payroll subject to annual Internal Revenue Code maximum limitations (with a $7,500 annual catch-up contribution permitted for those over 50 years old). The Company’s contribution percentage is 80% of the employee’s contribution up to the first 6% of the employee’s compensation. In addition, STAAR may make a discretionary contribution to qualified employees, in accordance with the 401(k) Plan. The Company’s contributions, net of forfeitures, to the 401(k) Plan were as follows (in thousands):
