PRESS RELEASE

CMC MaterialsReports Record Revenue and Record Diluted Earnings Per Share for the Full Fiscal Year 2020 and Financial Results for the Fourth Quarter of Fiscal 2020

Fourth Quarter

•Revenue of $274.2 Million, 1.6% Lower than Last Year Primarily Due to Decline in Pipeline Performance Products Revenue Due to COVID-19 Impact

•Diluted Earnings Per Share (EPS) of $1.25; Adjusted Diluted EPS1 of $1.96, 16.0% Higher than Last Year

Full Fiscal Year 2020

•Record Revenue of $1,116.3 Million, 7.6% Higher than Last Year Primarily Due to KMG Acquisition; Revenue Increased 1.5% Compared to Full Fiscal Year 2019 Pro Forma Revenue1 Primarily Due to Growth in CMP Slurries and Higher Wood Treatment Revenue

•Record Diluted EPS of $4.83, 257.8% Higher than Last Year; Record Adjusted Diluted EPS1 of $7.47, 11.0% Higher than Last Year

AURORA, IL, November 11, 2020 – CMC Materials, Inc.2 (Nasdaq: CCMP), a leading global supplier of consumable materials to semiconductor manufacturers and pipeline companies, today reported financial results for its fourth quarter and full fiscal year 2020, which ended September 30, 2020.

Key Highlights

Total revenue decreased 1.6% in the fourth quarter compared to the same quarter last year as stronger demand in CMP slurries and electronic chemicals as well as higher wood treatment revenue were offset by lower revenue in pipeline performance products and CMP pads. Net income for the quarter was $36.9 million compared to a loss of $20.2 million in the prior year primarily due to the impairment charge the company took for its strategic decision to exit the wood treatment business in the prior year. Adjusted EBITDA was $84.0 million, down 1.5% compared with the prior year. Full year revenue was a record and increased 7.6% compared to the last year primarily due to a full year of revenue from the company's acquisition of KMG Chemicals, Inc. in November of 2018, growth in CMP slurries and higher wood treatment revenue. During the year the company generated $287.3 million in cash flow from operations, and had $257.4 million of cash on hand and $921.4 million in total debt as of the end of the fiscal year.

“I am proud of our performance, delivering another year of record revenue and profitability despite the challenging and unprecedented environment caused by the COVID-19 pandemic, which demonstrates our strong execution and robust businesses. We are most grateful for the overall well-being of our employees, and I would like to thank our global teams for their dedication to driving our record results,” said David

Li, President and CEO of CMC Materials. “In fiscal 2021, we expect to see continued strong demand from our semiconductor customers driven by advanced node transitions to support new technologies including 5G, as well as improving fundamentals and demand from our pipeline customers. We also started the year with the rebranding of our company to CMC Materials, which we believe embodies our focus on delivering innovative, high value, specialty materials to our customers globally.”

2Formerly known as Cabot Microelectronics Corporation until October 1, 2020

Key Financial Information for the Fourth Quarter

•Revenue was $274.2 million, 1.6% lower than the revenue reported in the same quarter last year. Revenue was down 0.2% compared to the prior quarter primarily due to lower revenue in CMP pads and pipeline performance products, which more than offset higher revenue in CMP slurries and electronic chemicals.

•Net income was $36.9 million compared to a loss of $20.2 million last year. Adjusted net income was $58.0 million, 16.1% higher compared to adjusted net income in the prior year. Adjusted net income benefited from lower operating expenses, lower interest expense and lower taxes compared to the same quarter last year.

•Diluted EPS was $1.25. Adjusted diluted EPS was $1.96, 16.0% higher than adjusted diluted EPS in the same quarter last year.

•Adjusted EBITDA was $84.0 million, down 1.5% compared to last year. Adjusted EBITDA margin for the quarter was 30.6%, comparable to adjusted EBITDA margin of 30.6% in the same quarter last year.

Electronic Materials – Revenue was $222.8 million for the quarter, 2.5% higher than revenue in the same quarter last year. Higher revenue in CMP slurries and electronic chemicals more than offset lower revenue in CMP pads. Adjusted EBITDA was $71.4 million, or 32.0% of revenue.

Performance Materials– Revenue was $51.4 million for the quarter, 16.0% lower than revenue in the same quarter last year, driven primarily by a pandemic-related decline in demand for pipeline performance products. Higher revenue in the wood treatment and QED businesses partially offset this impact. Adjusted EBITDA was $22.4 million, or 43.6% of revenue.

Key Financial Information for the Full Fiscal Year 2020

•Revenue was a record $1,116.3 million, 7.6% higher than the revenue reported in the prior year primarily due to the full year impact of the KMG acquisition. Revenue was 1.5% higher compared to the $1,099.7 million pro forma revenue in the fiscal year 2019 primarily due to higher revenue in CMP slurries and wood treatment products.

•Net income was a record $142.8 million, 264.2% higher than the prior year. Adjusted net income was a record $220.8 million, 12.9% higher compared to adjusted net income in the prior year, and

11.3% higher than adjusted pro forma net income last year. The increase compared to adjusted pro forma net income was due primarily to higher revenue, lower operating expenses, and lower interest expense in fiscal year 2020.

•Diluted EPS was a record $4.83, 257.8% higher than the prior year. Adjusted diluted EPS was a record $7.47, 11.0% higher than adjusted diluted EPS in the prior year and 11.2% higher than adjusted pro forma diluted EPS in the prior year.

•Adjusted EBITDA was a record $357.8 million, up 7.3% compared to adjusted EBITDA last year and up 3.6% compared to adjusted pro forma EBITDA in the prior year. Adjusted EBITDA margin was 32.1%, compared to adjusted EBITDA margin of 32.1% and adjusted pro forma EBITDA margin of 31.4% in the prior year.

Guidance for the First Quarter and Full Fiscal Year 2021

With continued uncertainty as to the ongoing macroeconomic environment and the impact of the COVID-19 pandemic on the industries in which the company participates, the company currently expects revenue in the first quarter of fiscal 2021 to be approximately flat to up low single digits compared to the company’s revenue in the fourth quarter. Sequentially, Electronic Materials revenue is expected to be approximately flat to up low single digits and Performance Materials revenue is expected to be approximately flat.

The company currently expects full fiscal year 2021 adjusted EBITDA to be between $358 million and $385 million.

Additional current expectations are provided on slide 9 in the related slide presentation.

USE OF CERTAIN GAAP AND NON-GAAP ADJUSTED FINANCIAL INFORMATION

The company’s financial results are provided in accordance with accounting principles generally accepted in the United States of America (GAAP) and using certain non-GAAP financial measures. In particular, the Company presents the following non-GAAP financial measures: adjusted net income, adjusted diluted earnings per share, adjusted EBITDA, adjusted EBITDA margin, free cash flow, and net debt. The company has also presented the following non-GAAP pro forma measures: adjusted pro forma EBITDA, adjusted pro forma EBITDA margin, adjusted pro forma net income and adjusted pro forma diluted earnings per share. Adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, and excludes certain items that affect comparability from period to period. Adjusted EBITDA margin is defined as adjusted EBITDA as a percentage of revenue. The non-GAAP pro forma measures present the results as if the company’s acquisition of KMG Chemicals, Inc. (“KMG”)(“Acquisition”), had been included in the company’s results beginning October 1, 2018 and adjusts for certain items that affect comparability from period to period.

The non-GAAP financial measures provided in this press release is a supplement to, and not a substitute for, the company’s financial results presented in accordance with U.S. GAAP. These non-GAAP financial measures are provided to enhance the investor's understanding about the company's ongoing operations. Specifically, the company believes the impact of the adjustments related to the Acquisition, such as expenses incurred to complete the Acquisition and related integration and acquisition-related amortization expenses, costs of restructuring related to the wood treatment business and related adjustments in fiscal 2020, costs related to the KMG-Bernuth warehouse fire net of insurance recovery, costs incurred in fiscal 2020 related to the COVID-19 pandemic (“Pandemic”) net of grants received, the effects of Tax Cuts and Jobs Act in December 2017 in the United States (“Tax Act”) and the issued final regulations related to the Tax Act, and in fiscal 2019, impact of fair value adjustments to inventory acquired from KMG, are not indicative of its core operating results and thus presents these certain measures excluding these effects. The presentation of non-GAAP financial measures and non-GAAP pro forma measures is not meant to be considered in isolation or as a substitute for results prepared and presented in accordance with U.S. GAAP. Reconciliations of non-GAAP measures to their most comparable GAAP measures are included in the financial statements portion of this press release.

Adjusted EBITDA for the Electronic Materials and Performance Materials segments is presented in conformity with Accounting Standards Codification Topic 280, Segment Reporting. This measure is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing their performance. For these reasons, this measure is excluded from the definition of non-GAAP financial measures under the SEC Regulation G and Item 10(e) of Regulation S-K.

SUPPLEMENTAL UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following Unaudited Pro Forma Condensed Combined Financial Information is presented to illustrate the estimated effects of the company’s acquisition of KMG (the “Acquisition”), which was consummated on November 15, 2018 (the “Acquisition Date”), based on the historical results of operations of CMC Materials and KMG. The following Unaudited Pro Forma Condensed Combined Statements of Income for the twelve months ended September 30, 2019 are based on the historical financial statements of CMC Materials and KMG after giving effect to the Acquisition, and the assumptions and adjustments described in the accompanying notes to these Unaudited Pro Forma Condensed Combined Statements of Income.

The historical CMC Materials Consolidated Statement of Income for the twelve months ended September 30, 2019 was based upon and should be read in conjunction with, the CMC Materials historical audited consolidated financial statements and accompanying notes as of and for the year ended September 30, 2019 included in CMC Materials Annual Report on Form 10-K filed on November 27, 2019. The historical KMG Consolidated Statements of Income for the twelve months ended September 30, 2019 includes information derived from KMG’s books and records. Prior to the Acquisition, KMG was on a July 31st fiscal year end reporting cycle. These pro forma financials include KMG’s actual pre-acquisition results with the months aligned to CMC Materials’ fiscal periods, and therefore, they do not align with consolidated financial statements included in KMG’s Quarterly or Annual Reports on Form 10-Q or 10-K.

The Unaudited Pro Forma Condensed Combined Statements of Income are presented as if the Acquisition had been consummated on October 1, 2017, the first business day of our 2018 fiscal year, and combine the historical results of CMC Materials and KMG, which is consistent with internal management reporting, after primarily giving effect to the following assumptions and adjustments:

• Application of the acquisition method of accounting;

• Elimination of transaction costs incurred in connection with the Acquisition;

• Adjustments to reflect the new financing arrangements entered into and legacy financing arrangements retired in connection with the Acquisition;

• The exchange of 0.2000 share(s) of Cabot Microelectronics common stock for each share of KMG common stock; and

• Conformance of accounting policies.

The Unaudited Pro Forma Condensed Combined Financial Information was prepared using the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the completion of the acquisition. We utilized estimated fair values at the Acquisition Date to allocate the total consideration exchanged to the net tangible and intangible assets acquired and liabilities assumed. This allocation was completed in the first quarter of fiscal year 2020. 

The Unaudited Pro Forma Condensed Combined financial information has been prepared on the basis of SEC Regulation S-X Article 11 and is not necessarily indicative of the results of operations that would have been realized had the transactions been completed as of the dates indicated, nor are they meant to be indicative of our anticipated combined future results. In addition, the accompanying Unaudited Pro Forma Condensed Combined Statements of Income do not reflect any additional anticipated synergies, operating efficiencies, cost savings, or any integration costs that may result from the Acquisition.

The historical consolidated financial information has been adjusted in the accompanying Unaudited Pro Forma Condensed Combined Statements of Income to give effect to unaudited pro forma events that are (1) directly attributable to the transaction, (2) factually supportable and (3) are expected to have a continuing impact on the results of operations of the combined company. As a result, under SEC Regulation S-X Article 11, certain non-recurring expenses such as deal costs and compensation expenses related to severance or accelerated stock compensation and certain non-cash costs related to the fair value step-up of inventory are eliminated from pro forma results in the periods presented. Certain recurring historical KMG expenses related to depreciation, amortization, financing costs and costs of sales have been adjusted as if the Acquisition had occurred on October 1, 2017.

The Unaudited Pro Forma Condensed Combined Financial Information, including the related notes included herein, should be read in conjunction with CMC Materials’ Current Report on Form 8-K/A filed on January 30, 2019, as well as our consolidated financial statements included in this release and the historical consolidated financial statements and related notes of CMC Materials and KMG, which are available to the public at the SEC’s website at www.sec.gov.

Summary of Unaudited Pro Forma Adjustments

(in thousands)	Year Ended September 30, 2019
Impact to cost of sales:
Depreciation and amortization, net(a)	$	1,855
Inventory step-up(b)	(14,870)
Impact to cost of sales	$	(13,015)
Impact to operating expense:
Depreciation and amortization step up(a)	30,689
Asset impairment true up(c)	(16,186)
Compensation expense(d)	(38,099)

Impact to operating expense	$	(49,953)
Derivative fair value gain(f)	(567)
Interest expense(g)	(475)

Adjustments included in the accompanying Unaudited Pro Forma Condensed Combined Statements of Income are as follows:

a.Depreciation and amortization expense are adjusted by removing depreciation and amortization associated with legacy KMG assets and assigning a pro forma expense based on the fair value of the assets on the date of the Acquisition. For periods after the date of the Acquisition, there is no pro forma adjustment for Depreciation and actual booked depreciation is reflected on a straight-line basis. Depreciation costs are allocated to costs of sales and selling, general and administrative expenses based on historical KMG allocations. Amortization costs are allocated to costs of sales or selling, general and administrative expense based on the use of the asset, where applicable.

b.Cost of sales is impacted by increased inventory balance caused by the non-cash impact of the step up to fair value of the inventory. The incremental costs of sales driven by the inventory step-up during the period have been removed.

c.During the fiscal year ended September 30, 2019, an impairment charge in the amount of $67.4 million was incurred related to the Wood Treatment business, which was acquired from KMG. While still within the one-year remeasurement period after the Acquisition Date, it was determined that the facts and circumstances that triggered the impairment were not known, or could have been reasonably known, at the time of the transaction. Further, it was determined that the impairment charge was not directly attributable to the transaction and therefore, would not be wholly removed for purposes of pro forma reporting. Since the impairment charge taken for September 2019 reported results was based on the actual Acquisition Date while the pro forma financials are based upon an October 1, 2017 acquisition date, the pro forma adjustment of $16.2 million to reduce the impairment charge to $51.2 million for pro forma results is required. This adjustment reflects the difference between amortization and depreciation expense recognized post-acquisition from the earlier pro forma acquisition date vs. the amortization and depreciation expense recognized in reported results from the actual Acquisition Date. The impairment adjustment is tax effected at 25.3%, which considers the taxing jurisdictions where the impaired assets are held (United States and Mexico) and the period for which the impairment is deemed to have occurred (the twelve months ended September 30, 2019).

d.Directly attributable and non-recurring compensation expense related to non-recurring retention expenses and stock award vesting directly attributable to the Acquisition are removed for pro forma purposes. For KMG stock awards that were replaced by CMC Material stock awards in connection with the Acquisition, the vesting for on-going service expenses are added as a pro forma adjustment.

e.The elimination of non-recurring deal costs incurred in connection with the Acquisition.

f.As a result of the Acquisition, there were non-recurring costs incurred by KMG as a result of retiring old debt. The costs associated with retiring the old debt facility and other financial instruments are removed for pro forma purposes. These instruments were retired as a result of the Acquisition and are not included in the pro forma results, which are presented as if the Acquisition had occurred on October 1, 2017.

g.Changes in interest expense as a result of financing associated with the Acquisition. The adjustments remove legacy KMG interest costs, including unused revolver fees and adds the costs associated with the new financing facilities as if the Acquisition occurred on October 1, 2017. The calculation of interest expense considers the changing LIBOR rate and uses monthly period end averages from October 1, 2017 to September 30, 2019.

We calculated the income tax effect of the pro forma adjustments using a 21.4% tax rate, which represents the weighted average statutory tax rate for the year ended September 30, 2019.

We calculated the unaudited pro forma weighted average number of diluted shares outstanding by adding the number of shares issued in the Acquisition to the amount disclosed in the historical CMC Quarterly and Annual Reports on Form 10-Q and 10-K. The basic and diluted EPS calculation takes pro forma net income divided by the applicable number of shares outstanding.

Reconciliation of Pro Forma and Non-GAAP Adjusted Pro Forma Information

The company reports its financial results in accordance with U.S. GAAP and pro forma information in accordance with SEC Regulation S-X Article 11.  However, management believes that certain non-GAAP financial measures that reflect the way that management evaluates the business may provide investors with additional information regarding the company’s results, trends and ongoing performance on a comparable basis.  These measures, referred to as, “adjusted pro forma”, begin with pro forma results that are prepared in accordance with SEC Regulation S-X Article 11 and are then adjusted for the following additional items:

•Removal of amortization of acquisition related intangibles, since management believes that these costs are not indicative of the company’s core operating performance.

•Removal of integration expenses.

•Adjustment for U.S. Tax Reform, which represents a significant item affecting comparability among periods.

•Removal of certain costs related to a warehouse fire at KMG-Bernuth and the restructuring and asset impairment charges of wood treatment business.

Reconciliations for these items are provided below. Amounts in thousands, except per share and percentage amounts.
