Background and Basis of Presentation

BACKGROUND AND BASIS OF PRESENTATION

CMC Materials, Inc. (“CMC”, “the Company”, “us”, “we”, or “our”) is a leading global supplier of consumable materials, primarily to semiconductor manufacturers. The Company's products play a critical role in the production of advanced semiconductor devices, helping to enable the manufacture of smaller, faster and more complex devices by its customers. We operate our business within two reportable segments: Electronic Materials and Performance Materials. The Electronic Materials segment consists of our chemical mechanical planarization ("CMP") slurries business, CMP pads business, and electronic chemicals business. The Performance Materials segment consists of our pipeline and industrial materials (“PIM”) business, wood treatment business, and QED Technologies International, Inc. (“QED”) business.

The unaudited Consolidated Financial Statements have been prepared by CMC pursuant to the rules of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States of America (“U.S. GAAP” or “GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary for the fair statement of CMC’s financial position, cash flows, and results of operations for the periods presented. The results may not be indicative of the results that may be expected for the fiscal year ending September 30, 2021. This Report on Form 10-Q should be read in conjunction with the Consolidated Financial Statements and related notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

The Consolidated Financial Statements include the accounts of CMC and its subsidiaries. All intercompany transactions and balances between the companies have been eliminated.

In the Consolidated Statements of Cash Flows of this Quarterly Report on Form 10-Q, the presentation for Repurchases of common stock under Cash flows from financing activities has been updated for the first quarter of fiscal year 2020 to conform to the current presentation. The amount for that fiscal year that related to common shares withheld for taxes and included in Repurchases of common stock previously, is now presented separately under “Repurchases of common stock withheld for taxes.”

In the Consolidated Statements of Cash Flows of this Quarterly Report on Form 10-Q, the presentation for Provision for doubtful accounts has been updated for the first quarter of fiscal year 2020 to conform to the current presentation. The amount for that fiscal year that related to the Provision for doubtful accounts is now presented separately under “Other.”

USE OF ESTIMATES

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from these estimates under different assumptions or conditions.
