On July 4, 2025, tax legislation known as the One Big Beautiful Bill Act ("OBBBA") was enacted in the United States. OBBBA modifies certain international tax provisions such as the tax on Global Intangible Low Taxed Income ("GILTI") and renames GILTI as Net CFC Tested Income ("NCTI"). The Company records NCTI taxes on a deferred basis. The Company is currently evaluating the impact of U.S. tax law changes introduced by OBBBA on our consolidated financial statements. A quantitative

estimate of the specific financial impacts cannot be reasonably determined at this time due to the complexity of the changes in OBBBA and the need for further analysis.
