Financial Statements	NOTE 1: FINANCIAL STATEMENTS Unless the context indicates otherwise, Ryerson Holding Corporation ("Ryerson Holding") and its subsidiary companies are collectively referred to as “Ryerson,” or "the Company”. Ryerson Holding, a Delaware corporation, is the parent company of Joseph T. Ryerson & Son, Inc. (“JT Ryerson”), a Delaware corporation. Affiliates of Platinum Equity, LLC (“Platinum”) own 3,924,478 shares of common stock, which is approximately 7.6% of the Company's outstanding common stock as of June 30, 2026. Ryerson is a leading value-added processor and distributor of industrial metals with operations in the U.S. through JT Ryerson and other U.S. subsidiaries, including Olympic Steel, Inc. ("Olympic Steel"), which was added via merger on February 13, 2026, in Canada through its indirect wholly-owned subsidiary Ryerson Canada, Inc., a Canadian corporation (“Ryerson Canada”), and in Mexico through its indirect wholly-owned subsidiary Ryerson Metals de Mexico, S. de R.L. de C.V., a Mexican corporation (“Ryerson Mexico”). In addition to the North American operations, the Company conducts materials processing and distribution operations in China through an indirect wholly-owned subsidiary, Ryerson China Limited (“Ryerson China”), a Chinese limited liability company. Basis of Presentation The Company's Condensed Consolidated Financial Statements (Unaudited) as of June 30, 2026 and for the three-month and six-month periods ended June 30, 2026 and 2025 have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and therefore do not include all information and disclosures normally included in the annual Consolidated Financial Statements. The preparation of these Condensed Consolidated Financial Statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from these estimated amounts. In the opinion of the Company’s management, the Condensed Consolidated Financial Statements reflect all adjustments, which are normal and recurring in nature, and necessary for fair financial statement presentation. Results of operations for any interim period are not necessarily indicative of results for any future periods or for the year. The year-end Condensed Consolidated Balance Sheet data contained in this report was derived from audited financial statements, but does not include all disclosures required by GAAP. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Reclassifications During 2026, the Company reclassified the presentation of cash flows for the net change in book overdrafts from financing activities to operating activities in the Condensed Consolidated Statement of Cash Flows. Prior period amounts were reclassified to conform to the current period presentation, and in each period that amount is presented as a separate line within operating activities. The reclassification did not impact the Condensed Consolidated Balance Sheets or the Condensed Consolidated Statements of Comprehensive Income (Loss). Additionally, in the first six months of 2025, the Company presented its proceeds and repayments of borrowings under its revolving credit facility (“the Ryerson Credit Facility”) on a net basis as the borrowings had original maturities of three months or less and qualified for net presentation. Later in 2025 and in the first six months of 2026, the Company executed certain borrowings under the Ryerson Credit Facility with original maturities greater than three months and no longer qualified for net reporting. Thus the Company is presenting the borrowing activity on a gross basis in the statement of cash flows and has reclassified prior year presentation to conform with current year presentation for comparability.
