Organization, Description of the Business and Summary of Significant Accounting Policies	Organization, Description of the Business and Summary of Significant Accounting Policies Orion S.A.’s unaudited Condensed Consolidated Financial Statements include Orion S.A. and its subsidiaries (“Orion” or the “Company”). The unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. These financial statements should be read in conjunction with the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2025. The accompanying unaudited Condensed Consolidated Financial Statements include all adjustments that are necessary for the fair presentation of our results for the interim periods presented. These statements contain some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates. Results for interim periods are not necessarily indicative of results to be expected for the full year. Summary of Significant Accounting Policies—Accounting Standards Adopted Interim Reporting—In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. This ASU creates a comprehensive list of interim disclosures required under U.S. GAAP and incorporates a disclosure principle that requires disclosures at interim periods when an event or change that has a material effect on an entity has occurred since the previous year end. The guidance is effective for annual reporting periods beginning after December 15, 2027, and interim periods within those annual reporting periods. Early adoption is permitted. The ASU may be applied prospectively or retrospectively. On January 1, 2026, we adopted this ASU. The adoption of this ASU did not materially impact our Condensed Consolidated Financial Statements. Summary of Significant Accounting Policies—Accounting Standards Not Yet Adopted Government Grants—In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832), Accounting for Government Grants Received by Business Entities. This ASU adds guidance to the existing Accounting Standards Codification (“ASC”) 832, Government Assistance, on the recognition, measurement and presentation of a government grant received by a business entity. This guidance leverages the principles in the accounting framework for government assistance in International Financial Reporting Standards (“IFRS’), specifically IAS 20, Accounting for Government Grants and Disclosure of Government Assistance; makes certain targeted improvements; and modifies certain existing disclosure requirements in ASC 832. The guidance is effective for annual reporting periods beginning after December 15, 2028 and interim periods within those annual reporting periods. Early adoption is permitted. We are currently assessing the impact of adoption of this new ASU. However, we believe the adoption of this ASU will not materially impact our Consolidated Financial Statements. Intangible Assets—In September 2025, the FASB issued Accounting Standards Update No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). This ASU 2025-06 amends the existing standard that refers to various stages of a software development project to align better with current software development methods, such as agile programming. Under the new standard, entities will start capitalizing eligible costs when (1) management has authorized and committed to funding the software project, and (2) it is probable that the project will be completed and the software will be used to perform the function intended. In evaluating whether it is probable the project will be completed, an entity is required to consider whether there is significant uncertainty associated with the development activities of the software. The new guidance will be effective for all entities for annual periods beginning after December 15, 2027. The guidance can be applied on a fully prospective basis, a modified basis for in-process projects, or a full retrospective basis. We are currently assessing the impact of adopting the new guidance in our Consolidated Financial Statements. Consolidated Statements of Operations—In November 2024, the FASB issued Accounting Standards Update No. 2024-03, and in January 2025, ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”) and Clarifying the Effective Date (“ASU 2024-01”), respectively. These ASUs require public entities to disclose, on an annual and interim basis, disaggregated information about certain income statement expense line items. These ASUs do not change the expense captions an entity presents in the face of its Consolidated Statements of Operations. Rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the Consolidated Financial Statements. These ASUs are effective for fiscal years beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. We believe the adoption of these ASUs will not materially impact our Consolidated Financial Statements, however, will require additional disclosures in the footnotes to the Consolidated Financial Statements.

Intangible Assets—In September 2025, the FASB issued Accounting Standards Update No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”).

The new guidance will be effective for all entities for annual periods beginning after December 15, 2027. The guidance can be applied on a fully prospective basis, a modified basis for in-process projects, or a full retrospective basis.

We believe the adoption of these ASUs will not materially impact our Consolidated Financial Statements, however, will require additional disclosures in the footnotes to the Consolidated Financial Statements.
