(1)Entirely comprised of income taxes from the Canton of Zug.
The Company’s effective income tax rate for the year ended December 31, 2025 was higher than the Swiss
statutory rate due to the Company’s jurisdictional mix of earnings, and repatriation costs, which were partially
offset by changes in uncertain tax positions, percentage depletion, and a reduction in Pillar Two taxes from
new regulatory guidance.
The Company’s effective income tax rate for the year ended December 31, 2024 was higher than the Swiss
statutory rate due to the Company’s jurisdictional mix of earnings, changes in uncertain tax positions, and
Pillar Two taxes, which was offset by percentage depletion and return to provision adjustments.
The Company’s effective income tax rate for the year ended December 31, 2023 was higher than the Swiss
statutory rate due to the Company’s jurisdictional mix of earnings, changes in uncertain tax positions, and
return to provision adjustments, which was partially offset by percentage depletion.

The change in the net deferred income tax liabilities from December 31, 2024 to December 31, 2025 was
primarily driven by a repatriation cost deferred tax liability recorded on the current year unremitted earnings
that are not indefinitely reinvested. There was also an increase in the intangible deferred tax liability related to
goodwill and intellectual property tax amortization that exceeds book amortization.
As of December 31, 2025 and 2024, the Company had $752 million and $227 million, respectively, of gross
loss carryforwards, of which approximately $599 million and $181 million, respectively, related to U.S. state
gross loss carryforwards, and the remaining relates to Canada and Switzerland. The net operating loss and
credit carryforwards have various expiration dates from 2026 to an indefinite carryforward period in the
United States, expiration years of 2031 and 2032 in Switzerland, and various expiration years in Canada
ranging from 2032 to 2045.

The net change in the total valuation allowance for the years ended December 31, 2025 and 2024 was $53
million and $1 million, respectively. The 2025 movement is primarily related to the U.S valuation allowance
that was previously net with its respective net operating losses or state credit carryforwards.

As of December 31, 2025, the Company had $140 million of unrecognized tax benefits, accrued interest and
penalties, which would favorably impact the Company’s future tax rates in the event that the tax benefits are
eventually recognized. We include interest and penalties related to uncertain tax positions as a component of
income tax expense. For the years ended December 31, 2025, 2024 and 2023, the Company had accrued
interest and penalties totaling $49 million, $42 million and $32 million, respectively, as well as accrued
liabilities totaling $91 million, $125 million and $129 million, respectively. 
Our unrecognized tax benefits for uncertain positions are included within Other Non-current Liabilities on our
consolidated balance sheet.
Our unrecognized tax benefits decreased during 2025 primarily related to statute of limitations expirations,
which was partially offset by a net increase for tax positions related to the current and prior years in the U.S
and Canada.
Our unrecognized tax benefits increased during 2024 primarily due to an increase in tax positions related to
the current and prior years in the U.S and Canada partially offset by statute of limitations expirations.
Our unrecognized tax benefits increased during 2023 primarily due to an increase in tax positions related to
the current and prior years in the U.S and Canada partially offset by statute of limitations expirations.
The Company is subject to ongoing tax examinations in the United States and Canada. The specific timing of
when these open examinations will be concluded is uncertain. Tax controversies have substantially concluded
for U.S state income tax matters through 2020, and Canada through 2008.
Indefinite Reinvestment
Cumulative unremitted earnings of the Company’s U.S. and Canadian subsidiaries could be taxable if
repatriated in a future period. The unremitted retained earnings in the U.S. business are planned to be
reinvested indefinitely. However, due to additional cash needs in the U.S. to support anticipated acquisition
activity as well as anticipated plant refurbishment in Canada, the Canadian business plans to potentially
repatriate $550 million of the cumulative unremitted earnings and indefinitely reinvest remaining unremitted
earnings. The Company has recognized a deferred tax liability of approximately $23 million on the current
year unremitted earnings that are not indefinitely reinvested. Quantification of the deferred tax liability, if any,
associated with indefinitely reinvested earnings is not practicable. 
Recent Tax Law Changes
Effective January 1, 2024, the Company is subject to the 15% minimum tax rate provisions of the Organization
for Economic Co-operation and Development (“OECD”) Pillar Two framework enacted into law in both
Switzerland and Canada. Estimated Pillar Two top-up taxes of $12 million and $24 million have been included
in the calculation of the Company’s total income tax expense for the years ended December 31, 2025 and
2024, respectively. Further, in the first quarter of 2025, new legislation was introduced around Pillar Two that
resulted in the Company recognizing a benefit of $18 million.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law, which reinstates several
favorable tax provisions effective in 2025. The tax effects of the OBBBA have been recognized in the period
of enactment and did not have a material impact on our effective tax rate for the period ended December 31,
2025.
