NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited and in thousands, except per share amounts)
1. 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 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 Report on Form 10-Q, the presentation for the Provision for credit losses and the presentation for Repurchases of common stock under Cash flows from financing activities has been updated for the six months ended March 31, 2020 to conform to the current presentation. The amounts for that fiscal year related to the Provision for credit losses is now presented under “Other” and 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.”
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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS
Significant Accounting Policies and Estimates
There have been no material changes made to the Company’s significant accounting policies disclosed in Note 2 of "Notes to the Consolidated Financial Statements" included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.
Recently Adopted Accounting Pronouncements
Accounting Standards Update (“ASU”) No. 2016-13, “Measurement of Credit Losses on Financial Instruments” (Topic 326) and subsequent amendments, requires financial assets measured at amortized cost to be presented at the net amount expected to be collected using an allowance account and provides that credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. The Company adopted these standards effective October 1, 2020 using the modified retrospective approach, which did not impact our results of operations or financial condition. Upon adoption, no adjustment was made to retained earnings or the Allowance for credit losses at October 1, 2020.
8

INDEX
The Company is exposed to credit losses primarily through trade receivables for the sales of the Company’s products. The Company’s expected credit loss allowance for trade receivables is developed using historical credit loss experience and current and future economic and market conditions. The Company assesses credit risks for these trade receivables and groups them based on similar risk to determine the expected credit loss allowance. Due to the short-term nature of the Company’s trade receivables, the estimate of the expected credit loss allowance is mainly based on historical experience, accounts receivable balances, and the financial condition of customers.
ASU No. 2018-13 “Fair Value Measurement” (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, provides specific guidance on various disclosure requirements in Topic 820, including removal, modification and addition to current disclosure requirements. The Company adopted this standard effective October 1, 2020, which did not have a material impact on our financial statement disclosures.
ASU No. 2018-15 “Intangibles—Goodwill and Other—Internal-Use Software” (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, requires a customer in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset or expense related to the service contract. The Company adopted this standard effective October 1, 2020, which did not have a material impact on our results of operations or financial condition.
Accounting Pronouncements Issued But Not Yet Adopted
ASU No. 2019-12 “Income Taxes” (Topic 740): Simplifying the Accounting for Income Taxes, was issued to simplify Topic 740 through improving consistency and removing certain exceptions to general principles. ASU 2019-12 will be effective for us beginning October 1, 2021. We are currently evaluating the impact of implementing this standard on our financial statements.
ASU No. 2020-04 "Reference Rate Reform” (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” provides optional guidance for accounting for contracts, hedging relationships, and other transactions affected by the reference rate reform, if certain criteria are met. The provisions of this standard are available for election through December 31, 2022. We are currently evaluating the impact of the reference rate reform on our contracts and the resulting impact of adopting this standard on our financial statements.

3.  REVENUE FROM CONTRACTS WITH CUSTOMERS
The Company disaggregates revenue by product area and segment as it best depicts the nature and amount of the Company’s revenue. See Note 16 of this Report on Form 10-Q for more information.
The following table provides information about contract liability balances:

INDEX
4. FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company is required to record certain assets and liabilities at fair value. The valuation methods used for determining the fair value of these financial instruments by hierarchy are as follows:
Level 1Cash and cash equivalents consist of various bank accounts used to support our operations and investments in institutional money-market funds that are traded in active markets.
Other long-term investments represent the fair value of investments under our supplemental employee retirement plan ("SERP"). The fair value of the investments is determined through quoted market prices within actively traded markets.
Level 2
Derivative financial instruments include foreign exchange contracts and an interest rate swap contract. The fair value of our derivative instruments is estimated using standard valuation models and market-based observable inputs over the contractual term, including one-month London Inter-bank Offered Rate ("LIBOR") based yield curves for the interest rate swap, and forward rates and/or the Overnight Index Swap curve for forward foreign exchange contracts, among others.
Level 3No level 3 financial instruments
The following table presents financial instruments, other than debt, that we measure at fair value on a recurring basis. See Note 10 of this Report on Form 10-Q for a discussion of our debt. In instances where the inputs used to measure the fair value of an asset fall into more than one level of the hierarchy, we have classified it based on the lowest level input that is significant to the determination of the fair value.

6. GOODWILL
Goodwill activity for each of the Company’s reportable segments for the six months ended March 31, 2021:

Impairment (212,302)(212,302)
Balance at March 31, 2021$362,800 $147,824 $510,624 
During the second quarter, the Company recorded impairment charges related to the PIM and Wood treatment reporting units within the Performance Materials segment. Our PIM reporting unit continues to be adversely impacted by the COVID-19 Pandemic (“Pandemic”). During the second quarter, as a result of lower than anticipated recovery combined with a near-to-mid term increase in raw material cost for the PIM business, we determined that it is more likely than not that the fair value of the PIM reporting unit is below its carrying value, requiring the PIM reporting unit to be tested for impairment at March 31, 2021. Based on the results of the interim impairment test, the Company concluded that the carrying value of the PIM reporting unit exceeded the estimated fair value and recognized a non-cash, pre-tax goodwill impairment charge of $201,550 for the three months ended March 31, 2021. The remaining carrying value of the PIM reporting unit as of March 31, 2021 of $593,114 includes $118,564 of goodwill and $46,000 of indefinite lived intangible assets. The goodwill impairment charge is included in the Performance Materials segment and presented within Impairment charges and the related tax benefit of $23,539 for the three and six months ended March 31, 2021 is included in the (Benefit from) provision for income taxes in the Consolidated Statements of Income (Loss).
In performing the impairment test, the estimated fair value of the PIM reporting unit, was determined based on an average of a discounted cash flow model and a market approach based on earnings before interest, taxes, and depreciation for a group of guideline comparable companies. Key assumptions in estimating the fair value of the reporting unit included projected future revenue and gross margin, a 10.75% discount rate and a terminal growth rate of 3%. The Company’s projections for revenue and gross margin are based on the Company’s multiyear forecast. Components of the discount rate are the cost of equity and the cost of debt, each of which requires judgment by management to estimate. The Company developed its cost of equity estimate based on perceived risks and predictability of future cash flows. As the inputs for testing, including estimates of future revenue and gross margin, are not generally observable in active markets, the Company considers such measurements to be Level 3 measurements in the fair value hierarchy. The reporting unit’s carrying value used in an impairment test represents the assignment of various assets and liabilities, excluding certain corporate assets and liabilities, such as cash, investments, and debt. The Company estimated the fair value of its indefinite-lived intangible tradename utilizing its best estimate of future cash flows and royalty rate assumptions as of the period ending March 31, 2021.
Additionally, the Company recorded non-cash, pre-tax goodwill impairment charges of $6,671 and $10,752 for the three and six months ended March 31, 2021, related to the wood treatment asset group and reporting unit due to the planned closure of the facilities. See Note 7 of this Report on Form 10-Q for a discussion of the wood treatment impairment.
We continue to actively monitor the industries in which we operate and our businesses' performance for indicators of potential impairment. We perform an impairment assessment of goodwill and other intangible assets at the reporting unit level annually, or more frequently if circumstances indicate that the carrying value may not be recoverable, such as with respect to our PIM reporting unit. If current global macroeconomic conditions related to the Pandemic persist and continue to adversely impact our Company, we may have future additional impairments of goodwill or other intangible assets. Potential future impairments could be material to the Company’s Consolidated Balance Sheets and to the Consolidated Statements of Income (Loss), but we do not expect them to affect the Company’s reported Net cash provided by operating activities.

7. IMPAIRMENT - WOOD TREATMENT
As a result of our previously announced planned closure of the Company's wood treatment business’ facilities by approximately the end of calendar year 2021 and the finite remaining cash flow through the closure date, the Company concluded that it is more likely than not that the fair value of the wood treatment reporting unit is below its carrying value, requiring the wood treatment asset group and reporting unit to be tested for impairment.

INDEX
Impairment of Long-Lived Assets
As a result of the previously announced planned facility closures by approximately the end of calendar year 2021, the Company adjusted the remaining useful lives such that they do not extend beyond such date. The Company tested the recoverability of its long-lived assets and determined the carrying amount of the assets exceeded the sum of the expected undiscounted future cash flows, and as a result, we compared the fair value of the wood treatment asset group, which was determined based on a discounted cash flow model, to its carrying value. We recognized a non-cash pre-tax impairment charge of $3,266 for the quarter ended December 31, 2020 resulting in no remaining carrying value of definite-lived intangible assets or Property, plant and equipment as of that date. Key assumptions in testing the assets for recoverability and development of the fair value of the asset group included projected future revenue and gross margin. As the inputs for testing recoverability, including estimates of future revenue and gross margin, are not generally observable in active markets, the Company considers such measurements to be Level 3 measurements in the fair value hierarchy. The duration of the future revenue and gross margin estimates are limited to the period through the closure date.
Impairment of Goodwill
The fair value of the wood treatment reporting unit, which was determined based on a discounted cash flow model, did not exceed the carrying value of the reporting unit. Key assumptions in our goodwill impairment test included projected future revenue and gross margin. As a result, the Company recorded non-cash, pre-tax impairment charges of $6,671 and $10,752 for the three and six months ended March 31, 2021, respectively.
As the Company approaches the closure date of the facilities and there are finite estimated future cash flows, the carrying value of the wood treatment reporting unit will not be recoverable, resulting in future impairments of goodwill. The remaining carrying value of the wood treatment reporting unit as of March 31, 2021 includes $24.3 million of goodwill, which will be periodically impaired through the closure date, resulting in no fair value ascribed to the wood treatment business by the date of closure. The amount of the periodic impairments will vary depending on the timing of the remaining future cash flows of the business and carrying value of the reporting unit at each reporting period.
Presentation of Impairment Charges
The long-lived assets and goodwill impairment charges, both included in the Performance Materials segment, are presented within Impairment charges and the related tax benefit of $606 for the six months ended March 31, 2021 is included in the (Benefit from) provision for income taxes in the Consolidated Statements of Income (Loss). The impairment charges related to goodwill are not tax deductible, therefore there is no related tax benefit for the three months ended March 31, 2021. The impairment charges for wood treatment for the respective periods are as follows:
Three Months Ended March 31, 2021Six Months Ended March 31, 2021
Property, plant, and equipment, net$ $91

11. DERIVATIVE FINANCIAL INSTRUMENTS
We are exposed to various market risks, including risks associated with interest rates and foreign currency exchange rates.  We enter into certain derivative transactions to mitigate the volatility associated with these exposures. 
Cash Flow Hedges - Interest Rate Swap Contract
During the first quarter of fiscal 2021, the Company entered into a new interest rate swap agreement to extend the duration of its existing swap arrangement and to take advantage of lower interest rates. The existing interest rate swap, which was in a loss position of $35.3 million, was terminated, and the hedging relationship was de-designated. The liability for the terminated interest rate swap is not measured at fair value. The current and long-term portion of the liability for the terminated swap are recorded in Accrued expenses, income taxes payable and other current liabilities and Other long-term liabilities, respectively, on the Consolidated Balance Sheet and will be paid over the remaining term of the new swap. The loss amount for the terminated swap is included in Accumulated other comprehensive loss and will be amortized on a straight-lined basis into interest expense through January 31, 2024, the remaining term of the original swap.
The new interest rate swap is a floating-to-fixed interest rate swap contract to hedge the variability in LIBOR-based interest payments on a portion of our outstanding variable rate debt. The notional amount is scheduled to decrease quarterly and will expire on January 29, 2027. The new interest rate swap was designated as a cash flow hedge based on certain quantitative and qualitative assessments and we have determined that the hedge is highly effective and qualifies for hedge accounting.
Foreign Currency Contracts Not Designated as Hedges
We enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures. These foreign exchange contracts do not qualify for hedge accounting.

We expect approximately $14,120 to be reclassified from Accumulated other comprehensive income (loss) into Interest expense during the next twelve months related to our interest rate swap based on projected rates of the LIBOR forward curve as of March 31, 2021. This amount includes the amortization of the loss associated with the terminated swap arrangement.

12. COMMITMENTS AND CONTINGENCIES
In 2019, a fire occurred at the warehouse of the wood treatment facility of our subsidiary KMG-Bernuth, Inc (“KMG-Bernuth”), in Tuscaloosa, Alabama, which processes pentachlorophenol (“penta”) for sale to customers in the U.S. and Canada. The warehouse fire, which we believe originated from non-hazardous waste materials temporarily stored in the warehouse for recycling purposes, caused no injuries. KMG-Bernuth commenced and completed cleanup with oversight from certain local, state and federal authorities. We recorded expense for the fire waste cleanup and disposal of affected inventory in Cost of sales. No expense was recorded during the six months ended March 31, 2021. We recorded $593 of expense during the six months ended March 31, 2020. Although we believe we have completed cleanup efforts related to the fire incident, there are potential other costs that cannot be reasonably estimated as of this time related to the fire incident due to the nature of federally-regulated penta-related requirements. In addition, we continue to work with our insurance carriers on possible recovery of losses and costs related to the fire incident. During the three and six months ended March 31, 2021, we received an insurance recovery of $1,076. At this point we cannot reasonably estimate whether we will receive any additional insurance recoveries, or if so, the amount of such recoveries.
Separately, in connection with the acquisition of KMG Chemicals, Inc. (“Acquisition”), through KMG-Bernuth, we assumed a contingency related to the Star Lake Canal Superfund Site near Beaumont, Texas (“Star Lake”). In 2014, prior to the Acquisition, the United States Environmental Protection Agency (“EPA”) had notified KMG-Bernuth that the EPA considered it to be a potentially responsible party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, in connection with Star Lake. The EPA has estimated that related remediation will cost approximately $22.0 million. KMG-Bernuth and seven other cooperating parties entered into an agreement with the EPA in September 2016 to complete a remedial design of the remediation actions for the site. Although KMG-Bernuth has not conceded liability with respect to Star Lake, a reserve in connection with the remediation was established, and as of March 31, 2021, the reserve remaining was $204. The remediation work will be performed under a separate future agreement. For more information, refer to Note 20 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.
Purchase Obligations
We have $13,820 of contractual commitments under an abrasive particle supply agreement through December 2022.

During the first quarter of fiscal 2020, the Company adopted ASU No. 2018-02 regarding the reclassification of stranded tax effects resulting from the change in the U.S. federal corporate income tax rate under the Tax Cuts and Jobs Act (the “Tax Act”) and as a result, we reclassified $488 of stranded tax effects from Accumulated other comprehensive income to Retained earnings.

14. INCOME TAXES
The U.S. enacted the Consolidated Appropriations Act (“CAA”) in December 2020 and the American Rescue Plan (“Rescue Plan”) in March 2021. Both the CAA and Rescue Plan extend certain provisions of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and provide new Pandemic relief provisions. As with the CARES Act, the CAA and Rescue Plan did not have a material impact on our (Benefit for) provision for income taxes for the three and six months ended March 31, 2021.
As a result of Impairment charges recorded during the quarter, the Company recorded an income tax benefit of $16,109 for the three months ended March 31, 2021, compared to income tax expense of $7,144 for the three months ended March 31, 2020. The Company recorded an income tax benefit of $8,563 for the six months ended March 31, 2021, compared to income tax expense of $18,025 for the six months ended March 31, 2020. The Company’s effective income tax rate was 9.7% and 6.8% for the three and six months ended March 31, 2021, respectively, compared to an effective tax rate of 17.8% and 20.1% for the three and six months ended March 31, 2020, respectively. The changes in our effective tax rate for the three and six months ended March 31, 2021 compared to the prior year is primarily due to the unfavorable impact of the impairment related to the PIM and wood treatment reporting units, partially offset by higher tax benefit related to foreign derived intangible income.

16. SEGMENT REPORTING
We identify our segments based on our management structure and the financial information used by our chief executive officer, who is our chief operating decision maker, to assess segment performance and allocate resources among our operating units. We have the following two reportable segments:
Electronic Materials
Electronic Materials includes products and solutions for the semiconductor industry and consists of our CMP slurries business, CMP pads business, and electronic chemicals business.
Performance Materials
Performance Materials consists of our PIM business, wood treatment business, and QED business.
Our chief operating decision maker evaluates segment performance based upon revenue and segment adjusted EBITDA.  Segment adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, adjusted for certain items that affect comparability from period to period.  These adjustments include acquisition and integration-related expenses, certain costs related to the KMG-Bernuth warehouse fire, net of insurance recovery, impairment charges, net restructuring charges related to the wood treatment business, and costs related to the Pandemic, net of grants received. We exclude these items from earnings when presenting our adjusted EBITDA measure because we believe they are not indicative of a segment's regular, ongoing operating performance. Adjusted EBITDA is also the basis of a performance metric for our fiscal 2021 Short-Term Incentive Program ("STIP"). In addition, our chief operating decision maker does not use assets by segment to evaluate performance or allocate resources, and therefore, we do not disclose assets by segment.

This following discussion and analysis, should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2020, including the Consolidated Financial Statements and related notes thereto.

RECENT EVENTS
On April 1, 2021, CMC completed its acquisition of 100% of ITS, for approximately $125.0 million of cash, subject to post-closing adjustments, which was funded from cash on hand. The acquisition of ITS, which designs and produces high-performance consumables used to optimize critical semiconductor testing processes, expands the product offerings that are part of our Electronic Materials business segment.

SECOND QUARTER OF FISCAL 2021 OVERVIEW
While the Pandemic continues to cause significant global macroeconomic uncertainty and disruption worldwide and in the countries and locations in which we and our customers and suppliers operate, our business in our fiscal second quarter of 2021 showed continued resiliency and overall strength in our Electronic Materials segment. We have experienced solid demand from our semiconductor customers, which represents approximately 80% of our revenue, as certain sectors such as cloud, PCs and servers continued to show strength, continuing to be driven by work-from-home and e-learning environments, as well as the ongoing recovery in areas such as industrial and automotive sectors. Throughout the Pandemic, our primary focus has been and continues to be on the health and well-being of our employees and the ongoing operation of our facilities worldwide according to our business continuity plans, which we refine on an ongoing basis.
21

INDEX
To date, we have not seen a meaningful impact from the Pandemic on our ability to manufacture and deliver products to our customers, but the Pandemic has negatively impacted some of the industries we serve, primarily the oil and gas industry. The Pandemic has continued to have a negative effect on worldwide oil demand and transport, resulting in lower demand for our PIM products. As a result of lower than anticipated recovery and a near-to-mid term increase in raw material cost for the PIM business, we recorded an impairment charge of $201.6 million in our second fiscal quarter. However, we remain optimistic in our ability to drive growth in our PIM business, as the industry recovers and we execute on strategic initiatives, which include further developing our R&D product pipeline, and capturing new opportunities and market adjacencies.
In addition to the continued impact of the Pandemic, in February, the wood treatment and PIM reporting units were impacted by adverse weather across the southeast U.S., which caused some delays to operations and shipments. However, the adverse weather did not have a material impact on our quarterly results.
The extent to which the Pandemic may further impact our business, operations, results of operations and financial condition going forward is uncertain and difficult to estimate, and depends on numerous evolving and potentially unknown factors.
Second Quarter Key Financial Results
Our consolidated results of operations were as follows:

Adjusted EBITDA Margin29.2 %30.2 %
Our second quarter of 2021 consolidated revenue benefited from stronger demand for our CMP slurries products, partially offset by lower demand for our PIM products due to the Pandemic. Consolidated net (loss) income declined in the current year due to the impairment charges recorded for wood treatment and PIM, offset by impact of higher revenues. Adjusted EBITDA decreased due to higher professional fees.

Most of CMC’s foreign operations maintain their accounting records in their local currencies. As a result, period to period comparability of results of operations is affected by fluctuations in exchange rates. The impact on comparability is not material in any given period.
REVENUE
Revenue was $290.5 million for the three months ended March 31, 2021, which represented an increase of 2.2%, or $6.3 million, from the three months ended March 31, 2020, primarily due to stronger demand for the Company's CMP slurries products, partially offset by lower demand for PIM products due to the impact of the Pandemic.
Revenue was $578.4 million for the six months ended March 31, 2021, which represented an increase of 1.9%, or $11.1 million, from the six months ended March 31, 2020, primarily due to stronger demand for the Company's CMP slurries and electronic chemicals products and higher prices for the Company’s wood treatment products, partially offset by lower demand for PIM products due to the impact of the Pandemic.
COST OF SALES
Cost of sales was $166.8 million for the three months ended March 31, 2021, which represented an increase of 2.3%, or $3.7 million, from the three months ended March 31, 2020, primarily due to the increase in revenue and higher fixed costs.
Cost of sales was $331.7 million for the six months ended March 31, 2021, which represented an increase of 4.5%, or $14.2 million, from the six months ended March 31, 2020, primarily due to the increase in revenue and higher fixed costs as a result of the timing of the $5.3 million manufacturing variance recorded in the prior year.

INDEX
GROSS MARGIN
Our gross margin was 42.6% for the three months ended March 31, 2021, which was flat compared to 42.6% for the three months ended March 31, 2020. 
Our gross margin was 42.6% for the six months ended March 31, 2021, compared to 44.0% for the six months ended March 31, 2020. The decrease was primarily due to higher fixed costs as a result of the timing of manufacturing variance recorded in the prior year, partially offset by product mix and price increases.
SELLING, GENERAL AND ADMINISTRATIVE
Selling, general and administrative expenses were $58.5 million for the three months ended March 31, 2021, which represented an increase of 4.1%, or $2.3 million, from the three months ended March 31, 2020. This was primarily due to a $4.1 million increase in professional fees, partially offset by a $2.1 million decrease in amortization expense driven by impairment of intangible assets of the wood treatment business.
Selling, general and administrative expenses were $114.5 million for the six months ended March 31, 2021, which represented an increase of 3.4%, or $3.8 million, from the six months ended March 31, 2020. This was primarily due to a $4.7 million increase in professional fees and a $2.4 million increase in share-based compensation expense, partially offset by a $3.1 million decrease in amortization expense driven by impairment of intangible assets of the wood treatment business.
IMPAIRMENT CHARGES
Impairment charges were $208.2 million and $215.6 million for the three and six months ended March 31, 2021, respectively, due to impairment of goodwill in the PIM reporting unit, as well as the impairment of long-lived assets, intangible assets and goodwill of the wood treatment business as a result of the planned closure of the wood treatment facilities by approximately the end of calendar year 2021. There were no impairment charges during the three and six months ended March 31, 2020. See Notes 6 and 7 of "Notes to the Consolidated Financial Statements" of this Report on Form 10-Q for additional discussion.
INTEREST EXPENSE
Interest expense was $9.5 million for the three months ended March 31, 2021, which represented a decrease of $1.2 million from the three months ended March 31, 2020.  Interest expense was $19.1 million for the six months ended March 31, 2021, which represented a decrease of $3.6 million from the six months ended March 31, 2020.  The decreases were primarily due to a decline in the LIBOR rate for the unhedged portion of the Company's Term Loan Facility and a lower outstanding term loan balance due to repayments.
OTHER (EXPENSE) INCOME, NET
Other expense was $0.5 million for the three months ended March 31, 2021, compared to Other expense of $1.0 million for the three months ended March 31, 2020. The decrease in Other expense was primarily due to a lower loss on foreign currency transactions.
Other income was $1.0 million for the six months ended March 31, 2021, compared to Other expense of $1.4 million for the six months ended March 31, 2020. The change was primarily due to foreign currency gains.
(BENEFIT FROM) PROVISION FOR INCOME TAXES
As a result of Impairment charges recorded during the quarter, the Company recorded an income tax benefit of $16.1 million for the three months ended March 31, 2021, compared to income tax expense of $7.1 million for the three months ended March 31, 2020. The Company’s effective income tax rate for the second quarter of fiscal 2021 was 9.7%, compared to 17.8% in the same quarter last year. The change in our effective tax rate is primarily driven by the unfavorable impact of the impairment related to the PIM and wood treatment reporting units, partially offset by higher tax benefit related to foreign derived intangible income.
As a result of Impairment charges, the Company recorded an income tax benefit of $8.6 million for the six months ended March 31, 2021, compared to income tax expense of $18.0 million for the six months ended March 31, 2020. The Company’s effective income tax rate was 6.8% for the six months ended March 31, 2021, compared to 20.1% for the six months ended March 31, 2020.  The change in our effective income tax rate is primarily driven by the unfavorable impact of the impairment related to the PIM and wood treatment reporting units, partially offset by higher tax benefit related to share-based compensation and foreign derived intangible income.

INDEX
NET (LOSS) INCOME
Net loss was $149.8 million for the three months ended March 31, 2021, compared to Net income of $32.9 million for the three months ended March 31, 2020. Net loss was $118.3 million for the six months ended March 31, 2021, compared to Net income of $71.4 million the six months ended March 31, 2020.  The changes were due to impairment charges, partially offset by lower Interest expense.

ELECTRONIC MATERIALS
For the three months ended March 31, 2021 compared to the three months ended March 31, 2020, the $23.6 million increase in Electronic Materials revenue was primarily driven by increased demand for our CMP slurries, electronic chemicals, and CMP pads products. The $11.7 million increase in Electronic Materials adjusted EBITDA was primarily driven by the EBITDA associated with the increase in revenue, partially offset by higher fixed costs. The 170 bpts increase in Electronic Materials adjusted EBITDA margin was primarily driven by product mix, partially offset by higher fixed costs.
For the six months ended March 31, 2021 compared to the six months ended March 31, 2020, the $39.7 million increase in Electronic Materials revenue was driven by increased demand for our CMP slurries, electronic chemicals, and CMP pads products. The $11.3 million increase in Electronic Materials adjusted EBITDA was driven by the EBITDA associated with the increase in revenue, partially offset by higher fixed manufacturing costs as a result of the $5.3 million manufacturing variance recorded in the prior year. The 50 bpts decrease in Electronic Materials adjusted EBITDA margin was primarily due to higher fixed manufacturing costs.
PERFORMANCE MATERIALS
For the three months ended March 31, 2021 compared to the three months ended March 31, 2020, Performance Materials revenue decreased $17.3 million and adjusted EBITDA decreased $11.2 million. For the six months ended March 31, 2021 compared to the six months ended March 31, 2020, Performance Materials revenue decreased $28.7 million and adjusted EBITDA decreased $15.7 million. These decreases were driven by lower demand for PIM products due to the Pandemic, partially offset by higher sales for wood treatment products. For the three months ended March 31, 2021 compared to the three months ended March 31, 2020 adjusted EBITDA margin decreased 670 bpts and for the six months ended March 31, 2021 compared to the six months ended March 31, 2020 adjusted EBITDA margin decreased 290 bpts. These decreases were primarily driven by lower volume leverage for the PIM business, partially offset by higher selling prices for wood treatment products.

INDEX
USE OF CERTAIN GAAP AND NON-GAAP FINANCIAL INFORMATION
We provide certain non-GAAP financial measures, such as adjusted EBITDA and adjusted EBITDA margin, to complement reported GAAP results because we believe that analysis of our financial performance is enhanced by an understanding of these non-GAAP financial measures. We exclude certain items from earnings when presenting our adjusted EBITDA measure because we believe they will be incurred infrequently and/or are otherwise not indicative of the Company’s regular, ongoing operating performance. Accordingly, we believe that they aid in evaluating the underlying operational performance of our business, and facilitate comparisons between periods. In addition, adjusted EBITDA is used as one of the performance goals of our fiscal 2021 STIP. A similar adjusted EBITDA calculation is also used by our lenders for a key debt compliance ratio.
Adjusted EBITDA margin is defined as adjusted EBITDA as a percentage of revenue. Adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, adjusted for certain items that affect comparability from period to period. These adjustments include items related to acquisitions, such as Acquisition and integration-related expenses, impairment charges, costs of restructuring and related adjustments related to the wood treatment business, costs related to the KMG-Bernuth warehouse fire net of insurance recovery, and costs related to the Pandemic net of grants received.
The non-GAAP financial measures provided are a supplement to, and not a substitute for, the Company’s financial results presented in accordance with U.S. GAAP. Management strongly encourages investors to review the Company’s consolidated financial statements in their entirety and to not rely on any single financial measure. A reconciliation table of GAAP to non-GAAP financial measures is below.
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.

LIQUIDITY AND CAPITAL RESOURCES
As of March 31, 2021, we had $324.8 million of cash and cash equivalents compared with $257.4 million as of September 30, 2020. On March 31, 2021, $116.4 million of cash and cash equivalents was held in foreign subsidiaries. Our total liquidity as of March 31, 2021 was $524.8 million compared to $457.4 million as of September 30, 2020 (including $200.0 million of borrowing availability under our Revolving Credit Facility in both periods, which includes our letter of credit sub-facility). The increase in liquidity reflects the cash flow provided by operating activities, partially offset by the cash used for additions of property, plant and equipment, the repurchases of our common stock and payments of quarterly cash dividends.
On April 1, 2021, we completed the acquisition of ITS for approximately $125.0 million in cash, which was funded from cash on hand as of March 31, 2021.
Total debt, consisting of principal outstanding on our Term Loan Facility, amounted to $917.6 million ($931.0 million in aggregate principal amount less $13.5 million of debt issuance costs) as of March 31, 2021 and $921.4 million ($936.4 million in aggregate principal amount less $14.9 million of debt issuance costs) as of September 30, 2020. During the three months ended March 31, 2021 there were no borrowings under our Revolving Credit Facility and no balance was outstanding as of March 31, 2021.
The Revolving Credit Facility requires that the Company maintain a maximum first lien secured net leverage ratio, as defined in the Amended Credit Agreement, of 4.00 to 1.00 as of the last day of each fiscal quarter. As of March 31, 2021, our maximum first lien secured net leverage ratio was 1.59 to 1.00. Additionally, the Amended Credit Agreement contains certain affirmative and negative covenants that limit the ability of the Company, among other things and subject to certain significant exceptions, to incur debt or liens, make investments, enter into certain mergers, consolidations, asset sales and acquisitions, pay dividends and make other restricted payments and enter into transactions with affiliates. We are in compliance with these covenants as of March 31, 2021 and we expect to remain in compliance with our debt covenants during fiscal 2021 and beyond.
In March 2021, our Board of Directors authorized an increase in the amount available under our share repurchase program to $150.0 million. During the second quarter of fiscal 2021, we repurchased 5 thousand shares under the former authorization, and $150.0 million authorization remained at the end of the quarter. The timing, manner, price and amounts of repurchases are determined at the Company's discretion, and the share repurchase program may be suspended, terminated or modified at any time for any reason. The repurchase program does not obligate the Company to acquire any specific number of shares. To date, we have funded share purchases under our share repurchase program from our available cash on hand, and anticipate we will continue to do so.
Our Board of Directors authorized the initiation of our regular quarterly cash dividend program in January 2016, and since that time has increased the dividend to its current level of $0.46 per share. The declaration and payment of future dividends is subject to the discretion and determination of the Board of Directors and management, based on a variety of factors, and the program may be suspended, terminated or modified at any time for any reason.
We believe that cash on hand, cash available from future operations, and available borrowing capacity under our Amended Credit Agreement will be sufficient to fund our operations, expected capital expenditures, dividend payments, and share repurchases for at least the next twelve months. However, there remains ongoing Pandemic-created uncertainty in worldwide economic conditions and in those of the industries in which we participate, and whether with respect to the impact of the Pandemic or in pursuit of corporate development or other initiatives, we may need to raise additional funds in the future through equity or debt financing, or other arrangements. Depending on future conditions in the capital and credit markets, we could encounter difficulty securing additional financing in the type or amount necessary to pursue these objectives.
Operating Activities
We generated $123.5 million in cash flows from operating activities in the first six months of fiscal 2021, compared to $112.3 million in the first six months of fiscal 2020. The increase in operating cash flows was due to $9.2 million of changes in operating assets and liabilities and a $2.0 million increase of Net income adjusted for non-cash reconciling items.
Investing Activities
In the first six months of fiscal 2021, net cash used in investing activities was $20.8 million, compared to $57.6 million in the first six months of fiscal 2020. This was primarily driven by a decrease in capital expenditures of $38.1 million in the first six months of fiscal 2021 compared to the first six months of fiscal 2020 driven by the plant expansion in fiscal 2020 in our Performance Materials segment.

INDEX
Financing Activities
In the first six months of fiscal 2021, cash flows used in financing activities were $36.7 million, compared to cash flows provided by financing activities of $98.1 million in the first six months of fiscal 2020. This was mainly driven by the draw on the Company’s revolving credit facility for $150.0 million during the first six months of fiscal 2020 as a precautionary measure to preserve financial flexibility at the onset of the Pandemic. This was partially offset by repayments under the Term Loan Facility of $5.3 million in the first six months of fiscal 2021 compared to $18.0 million in the first six months of fiscal 2020, as well as cash paid for repurchases of common stock under the Share Repurchase Program of $10.0 million in the first six months of fiscal 2021 compared to $16.4 million in the first six months of fiscal 2020.

OFF-BALANCE SHEET ARRANGEMENTS
At March 31, 2021 and September 30, 2020, we did not have any unconsolidated entities or financial partnerships.

CONTRACTUAL OBLIGATIONS
There have been no material changes to the Company's contractual obligations during fiscal 2021, except as discussed below.
As of March 31, 2021, the Company had a purchase agreement to acquire ITS for approximately $125.0 million in cash, subject to post-closing adjustments. This acquisition closed on April 1, 2021.
We have been operating under a multi-year supply agreement for the purchase of certain raw materials, which runs through December 2022. As of March 31, 2021, purchase obligations include an aggregate amount of $13.8 million of contractual commitments related to this agreement.
Refer to Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020, for additional information regarding our contractual obligations.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES AND EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
There were no material changes from the “Quantitative and Qualitative Disclosures about Market Risk” disclosed in Part II Item 7A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

ITEM 4. CONTROLS AND PROCEDURES
EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES
Our management, with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), has conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”), as of March 31, 2021.  Based on that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and to ensure that such information is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
INHERENT LIMITATIONS ON EFFECTIVENESS OF CONTROLS
Because of inherent limitations, our disclosure controls or our internal control over financial reporting may not prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
We periodically become a party to legal proceedings, arbitrations, regulatory proceedings, inquiries and investigations (“contingencies”) arising in the ordinary course of our business operations. The ultimate resolution of these contingencies is subject to significant uncertainty, and should we fail to prevail in any of them or should several of them be resolved against us in the same reporting period, these matters could, individually or in the aggregate, be material to our consolidated financial statements. One of these contingencies, related to Star Lake Canal, which we assumed in connection with the Acquisition, is discussed in Note 12 of “Notes to the Consolidated Financial Statements” included in Item 1 of Part I of this Report on Form 10-Q. The ultimate outcome of these matters, however, cannot be determined at this time, nor can the amount of any potential loss be reasonably estimated, and as a result except where indicated no amounts have been recorded in our consolidated financial statements.
We also may face other governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with Star Lake Canal or other past and present operations. We accrue for environmental liabilities when a determination can be made that they are probable and reasonably estimable. Other than as described herein, we are not involved in any legal proceedings that we believe could have a material impact on our consolidated financial position, results of operations or cash flows. The information set forth in Item 1.A. Risk Factors, and Note 12 of “Notes to the Consolidated Financial Statements” included in Item 1 of Part I of this Report on Form 10-Q, is incorporated herein by reference.

ITEM 1A. RISK FACTORS
RISKS RELATING TO OUR BUSINESS, STRATEGY AND OPERATIONS
OUR BUSINESS AND RESULTS OF OPERATIONS MAY BE ADVERSELY AFFECTED BY THE CORONAVIRUS (COVID-19) PANDEMIC AND RELATED ADVERSE IMPACT TO WORLDWIDE ECONOMIC AND INDUSTRY CONDITIONS
The global impact of the Pandemic has created significant volatility, uncertainty and economic disruption across the world and in the countries and locations in which we and our customers and suppliers operate. In the second half of our fiscal year 2020, businesses in our Electronic Materials segment remained generally stable, and showed some strengthening in the first half of fiscal 2021, despite the Pandemic. With respect to our Performance Materials segment, the Pandemic has had a significant adverse impact on our Performance Materials’ PIM business during the second half of our fiscal year 2020 continuing into the first half of our fiscal year 2021, as the demand for drag reducing agents (“DRAs”) declined significantly due to the ongoing dislocation in the energy sector occasioned by the Pandemic. Although this business has appeared to stabilize somewhat in our first half of fiscal 2021 and we are optimistic in our ability to drive future growth in our PIM business as the industry recovers, recovery has been lower than anticipated, and as described in Note 6 of this Report on Form 10-Q, certain factors related to it continue to adversely affect the PIM reporting unit. The extent to which the ongoing Pandemic may further impact our business, operations, results of operations and financial condition is uncertain and difficult to estimate, and depends on numerous evolving factors that we may not be able to accurately predict, which may include: An additional decrease in short-term and long-term demand and pricing for our products and services, and an ongoing global economic recession that could further reduce demand and/or pricing for our products and services resulting from actions taken by governments, businesses, or the general public in an effort to limit exposure to and spread of such infectious diseases, such as ongoing or renewed travel restrictions, quarantines, and business shutdowns or slowdowns; Negative impacts to our operations, including reductions in production levels, research and development ("R&D") activities, and qualification activities with our customers, and increased costs resulting from our efforts to mitigate the impact of the Pandemic through additional or continued social-distancing measures we have enacted at our locations around the world in an effort to protect our employees’ health and well-being (including working from home, reducing the number of employees or others in our sites at any one time and how such individuals perform work while at our sites, redesigning or adjusting our manufacturing, R&D and office facilities, and suspending or limiting employee travel); Deterioration of worldwide credit and financial markets that could limit our ability to obtain external financing to fund our operations and capital expenditures, result in losses on our holdings of cash and investments due to failures of financial institutions and other parties, and result in losses on our accounts receivables due to credit defaults or our customers’ inability to pay; and, Disruptions to our supply chain in connection with the sourcing of or pricing for materials, equipment and logistics or other services and support necessary to our business as a result of the Pandemic and efforts to contain the spread of the Pandemic. Although the rollout of vaccination programs in the U.S., Europe, parts of Asia and other places in which we operate is encouraging with respect to the containment and abatement of the Pandemic, the resumption of what was previously considered normal business operations after such interruption remains uncertain, and may be further delayed or constrained by lingering effects of the Pandemic on our Company and our customers, suppliers, and third-party service providers. These effects, alone or taken together, could have a material adverse effect on our business, results of operations, legal exposure, or financial condition; an example of such effect is the impairment charge related to our PIM business described in Note 6 of this Report on Form 10-Q. A further sustained or prolonged outbreak or return of the Pandemic in the places in which we do business, such as that seen in the U.S., Europe, and parts of Asia during the first half of our fiscal 2021, could exacerbate the adverse impact of such measures on our Company.

INDEX
DEMAND FOR OUR PRODUCTS FLUCTUATES AND OUR BUSINESS MAY BE ADVERSELY AFFECTED BY WORLDWIDE ECONOMIC, INDUSTRY AND OTHER CONDITIONS
Our business is affected by economic and industry conditions, such as those still being adversely affected by the Pandemic, and the majority of our revenue derives from our Electronic Materials segment, which is primarily dependent upon semiconductor industry demand. With respect to our Electronic Materials segment, historically, semiconductor industry demand has fluctuated due to economic and industry cycles and seasonal shifts in demand, which can affect our business, causing demand for our electronic materials products to fluctuate. For example, prior to the Pandemic, the relatively soft demand conditions in the semiconductor industry that had commenced in our second fiscal quarter of 2019 and continued into our first fiscal quarter of 2020 had begun to ameliorate in the beginning of the second fiscal quarter of 2020. While our Electronic Materials segment experienced relatively stable conditions during the second half of fiscal 2020 and has showed some strengthening in the first half of fiscal 2021, uncertainty remains as to fiscal 2021 demand conditions for the semiconductor industry given the ongoing nature of the Pandemic, including supply constraints at our customers serving certain areas, such as automotive and industrial sectors. Furthermore, competitive dynamics within the semiconductor industry may impact our business. Our limited visibility to future customer orders makes it difficult for us to predict industry trends, especially during unusual adverse circumstances, such as the Pandemic. If the global economy or the semiconductor industry fails to continue to improve or weakens again, whether in general or as a result of the Pandemic or other specific factors, such as macroeconomic factors, or unpredictable events such as natural disasters, geopolitical conditions and international trade tensions, civil unrest, or additional global health crises, we could experience material adverse impacts on our results of operations and financial condition. Some additional factors that may affect demand for our electronic materials products include: demand trends for different types of electronic devices, such as logic versus memory integrated circuit ("IC") devices, or digital versus analog IC devices; the various technology nodes at which those products are manufactured; customers' efficiencies in the use of CMP consumables and/or high-purity process chemicals (“electronic chemicals”); customers' device architectures and specific manufacturing processes; the short order to delivery time for our products; quarter-to-quarter changes in customer order patterns; market share and competitive gains and losses; and pricing changes by us and our competitors.
As to our Performance Materials segment, our PIM business may continue to be impacted by changes in the utilities and/or oil and gas industries, such as we have seen since the second half of our fiscal 2020 and through our first half of fiscal 2021 resulting from ongoing significant dislocation in these industries occasioned by the Pandemic. Relatedly, as described, volatility in oil and natural gas prices may impact our customers’ activity levels, including production, and as we saw during the last four fiscal quarters, we experienced a significant drop in demand for our related PIM products and services, although demand appears to have stabilized somewhat in our first half of fiscal 2021. Expectations about future prices and price volatility are important in determining future spending levels for customers of our PIM products and services. The ongoing volatility in worldwide oil and natural gas prices and markets are an extreme example of historical volatility in this sector, and such volatility is likely to continue in the future. As is currently the case, prices for oil and natural gas are subject to wide fluctuations in response to relatively minor or major changes in the supply of and demand for oil and natural gas, market uncertainty and a variety of additional factors that are beyond our control. These factors include, but are not limited to, decreases or increases in supplies from U.S. shale production or other oil production, geopolitical conditions, including uprisings, civil unrest, and international trade tensions, sovereign debt crises, the domestic and foreign supply of oil and natural gas, the level of consumer demand due to economic growth or contraction such as seen related to the Pandemic, and other factors in countries such as China, weather conditions, domestic and foreign governmental regulations and taxes, the price and availability of alternative fuels, the health of international economic and credit markets, the ability of the members of the Organization of the Petroleum Exporting Countries (“OPEC”) and other state-controlled oil companies to agree upon and maintain oil price and production controls, and general economic conditions, such as those currently seen related to the Pandemic.
Further, adverse global economic, industry and other conditions such as those related to the Pandemic could have other negative effects on our Company. For instance, we could experience negative impacts on cash flows due to the inability of our customers to pay their obligations to us, or our production processes could be harmed if our suppliers cannot fulfill their obligations to us. As a result of these or other conditions, and as experienced in our second fiscal quarter with the impairment charge we took in our PIM business unit, further described in Note 6 of this Report on Form 10-Q, we also might have to further reduce the carrying value of goodwill and other intangible assets, which could harm our financial position and results of operations.
33

INDEX
WE MAY PURSUE ACQUISITIONS OF, INVESTMENTS IN, AND MERGERS OR STRATEGIC ALLIANCES WITH OTHER ENTITIES, WHICH COULD DISRUPT OUR OPERATIONS AND HARM OUR OPERATING RESULTS IF THEY ARE UNSUCCESSFUL, OR WE MAY ENCOUNTER UNANTICIPATED ISSUES IN IMPLEMENTING THEM
We expect to continue to make investments in technologies, assets and companies, either through acquisitions, mergers, investments or alliances, in order to supplement our organic growth and development efforts. Acquisitions, mergers, and investments, including the Acquisition, which we completed in November 2018, involve numerous risks, including the following: difficulties and risks in integrating the operations, technologies, products and personnel of acquired companies; difficulties and risks from unanticipated issues arising subsequent to a transaction related to the other entity; potential disruption of relationships with third parties such as customers or suppliers; diversion of management's attention from normal daily operations of the business; increased risk associated with foreign operations; potential difficulties and risks in entering markets or industries in which we have limited or no direct prior experience and/or where competitors have stronger positions; potential difficulties and unexpected situations arising in operating new businesses with different business models; facilities and operations; potential difficulties with regulatory or contract compliance in areas in which we have limited or no experience; initial dependence on unfamiliar supply chains or relatively small supply partners; insufficient revenue to offset increased expenses associated with acquisitions; potential loss of key employees of the acquired companies; or inability to effectively cooperate and collaborate with our alliance partners.
Further, we may never realize the perceived or anticipated benefits of a business combination or merger with, or asset or other acquisition of, or investments in, other entities. Transactions such as the Acquisition could and in some cases have had negative effects on our results of operations, in areas such as contingent liabilities, gross margins, amortization charges related to intangible assets and other effects of accounting for the purchases of other business entities. Investments in and acquisitions of technology-related or early-stage companies or assets are inherently risky because these businesses or assets may never develop, and we may incur losses related to these investments.
In addition, we may be required to impair the carrying value of these acquisitions or investments to reflect other than temporary declines in their value. The carrying value of goodwill represents the fair value of acquired businesses in excess of identifiable assets and liabilities as of the acquisition date. The carrying value of other intangible assets represents the fair value of customer relationships, tradenames and other acquired intangible assets as of the acquisition date. Goodwill and other acquired intangible assets expected to contribute indefinitely to our cash flows are not amortized, but must be evaluated for impairment by management at least annually. If the carrying value exceeds the implied fair value of goodwill, the goodwill is considered impaired and is reduced to fair value via a non-cash charge to earnings. If the carrying value of an indefinite-lived intangible asset is greater than its fair value, the intangible asset is considered impaired and is reduced to fair value via a non-cash charge to earnings. If the value of goodwill or other acquired intangible assets is impaired, our results of operations and financial condition could be adversely affected. Examples of asset impairment charges we recently incurred include the charge we took in the second quarter of fiscal 2021 related to the PIM business unit and the charge we took in each the fourth quarter of fiscal 2019, the fourth quarter of fiscal 2020, and the first two quarters of fiscal 2021 related to the KMG wood treatment business. We expect that the carrying value of the wood treatment reporting unit will not be recoverable, resulting in future impairments of goodwill. The amount of such impairments could be material and could adversely affect our results of operations and financial condition. See Notes 6 and 7 of "Notes to the Consolidated Financial Statements" of this Report on Form 10-Q for additional discussion.
Furthermore, the integration of the acquired businesses into our operations is a complex and time-consuming process that may not be successful. Our Company has a limited history of integrating significant acquisitions, and the process of integration may produce unforeseen operating difficulties and expenditures. As demonstrated in the Acquisition, the primary areas of focus for successfully combining those businesses with our operations may include and have included, among others: retaining and integrating key employees; realizing synergies; aligning customer and supplier interfaces, and operations across the combined business; integrating enterprise resource planning and other information technology systems; and, managing the growth of the combined company. Even if we successfully integrate an acquired business, such as KMG, into our operations, there can be no assurance that we will realize the anticipated benefits of the Acquisition.
34

INDEX
WE HAVE A CONCENTRATED PRODUCT RANGE WITHIN EACH OF OUR SEGMENTS AND OUR PRODUCTS MAY BECOME OBSOLETE, OR TECHNOLOGICAL CHANGES MAY REDUCE OR LIMIT INCREASES IN THE CONSUMPTION OF OUR PRODUCTS
Although our product offerings have expanded over the past several years, including as a result of the Acquisition, our business remains substantially dependent on products in our Electronic Materials segment, such as CMP slurries, pads and electronic chemicals, which account for the majority of our revenue. The product offerings in our Performance Materials segment are similarly concentrated. As such, our business would suffer if these products became obsolete or if consumption of these products decreased. Our success depends on our ability to keep pace with technological changes and advances in the industries in which we operate, particularly the semiconductor industry, and to adapt, improve and customize our products in response to evolving customer needs and industry trends. Since its inception, the semiconductor industry, which is the largest industry in which we operate, has experienced technological changes and advances in the design, manufacture, performance and application of IC devices. Our customers continually pursue lower cost of ownership and higher quality and performance of materials consumed in their manufacturing processes, including CMP slurries and pads and electronic chemicals, as a means to reduce costs, increase the yield in their manufacturing facilities, and achieve desired performance of the IC devices they produce. We expect these technological changes, and this drive toward lower costs, higher quality and performance and higher yields, will continue in the future. Potential technology developments in the semiconductor industry, as well as our customers' efforts to reduce consumption of CMP consumables, including through use of smaller quantities, could render our products less important to the IC device manufacturing process.
A SIGNIFICANT AMOUNT OF OUR BUSINESS COMES FROM A LIMITED NUMBER OF LARGE CUSTOMERS AND OUR REVENUE AND PROFITS COULD DECREASE SIGNIFICANTLY IF WE LOST ONE OR MORE OF THESE CUSTOMERS OR BUSINESS FROM THEM
Our customer base is concentrated among a limited number of large customers in each of our segments. Currently, our principal business supplies electronic materials primarily to the semiconductor industry. The semiconductor industry has been consolidating as the larger semiconductor manufacturers have generally grown faster than the smaller ones, through business gains, mergers and acquisitions, and strategic alliances. Industry analysts predict that this trend will continue, which means the semiconductor industry will continue to be comprised of fewer and larger participants in the future if their prediction is correct. In addition, our customer base in our PIM business is also somewhat concentrated, with large entities predominant, and outside of the U.S., these entities frequently are state-owned or sponsored, and limited in number per country. One or more of these principal customers could stop buying products from us or could substantially reduce the quantity of products purchased from us. Our principal customers in both our segments also hold considerable purchasing power, which can impact the pricing and terms of sale of our products. Any deferral or significant reduction in the quantity or price of products sold to these principal customers could seriously harm our business, financial condition and results of operations.
ANY PROBLEM OR DISRUPTION IN OUR SUPPLY CHAIN, INCLUDING SUPPLY OF OUR MOST IMPORTANT RAW MATERIALS, OR IN OUR ABILITY TO MANUFACTURE OR DELIVER OUR PRODUCTS TO OUR CUSTOMERS, COULD ADVERSELY AFFECT OUR RESULTS OF OPERATIONS
We depend on our supply chain to enable us to meet the demands of our customers. Our supply chain includes the raw materials we use to manufacture our products, our production operations and the means by which we deliver our products to our customers. Our business could be adversely affected by any problem or interruption in the supply of the key raw materials we use in our products, including raw materials that do not meet the stringent quality and consistency requirements of our customers, any problem or interruption that may occur during production or delivery of our products, such as weather-related problems, natural disasters, global public health crises such as the ongoing Pandemic, geopolitical, trade or labor-related issues, civil unrest, or any difficulty in producing sufficient quantities of our products to meet growing demand from our customers. In particular, severe weather conditions have the potential to adversely affect our operations, damage facilities and increase our costs, and those conditions may also have an indirect effect on our operations by disrupting services provided by service companies or suppliers with whom we have a business relationship. Additionally, some of our full-time employees are represented by labor unions, works councils or comparable organizations, particularly in Mexico and Europe. An extended work stoppage, slowdown or other action by our employees could significantly disrupt our business. As our current agreements with labor unions and works councils expire, we cannot provide assurance that new agreements will be reached at the end of each period without union action, or that a new agreement will be reached on terms satisfactory to us. Future labor contracts may be on terms that result in higher labor costs to us, which also could adversely affect our results of operations. Our supply chain may also be negatively impacted by unanticipated price increases due to supply restrictions beyond the control of our Company or our raw materials suppliers, such as those related to or arising from the Pandemic.
35

INDEX
We believe it would be difficult to promptly secure alternative sources of key raw materials in the event one of our suppliers becomes unable to supply us with sufficient quantities of raw materials that meet the quality and technical specifications required by us and our customers. In addition, new contract terms, forced production or manufacturing changes, contractual amendments to existing agreements with, or non-performance by, our suppliers, including any significant financial distress our suppliers may suffer, could adversely affect us. Also, if we change the supplier or type of key raw materials we use to make our products, in particular our electronic materials products, or are required to purchase them from a different manufacturer or manufacturing facility or otherwise modify our products, in certain circumstances our customers might have to requalify our products for their manufacturing processes and products. The requalification process could take a significant amount of time and expense to complete and could occupy technical resources of our customers that might otherwise be used to evaluate our new products, thus delaying potential revenue growth, or motivate our customers to consider purchasing products from our competitors, possibly interrupting or reducing our sales of products to these customers, especially sales of our electronic materials products to our semiconductor industry customers, but also with respect to our PIM products to our pipeline and adjacent industry customers.
OUR BUSINESS COULD BE SERIOUSLY HARMED IF OUR COMPETITORS DEVELOP COMPETITIVE PRODUCTS, OFFER BETTER PRICING, SERVICE OR OTHER TERMS, OR OBTAIN OR ASSERT CERTAIN INTELLECTUAL PROPERTY RIGHTS
Competition from other electronic materials or performance materials providers or any new entrants could seriously harm our business and results of operations, and this competition could continue to increase. Competition has and will likely continue to impact the prices we are able to charge for our products, as well as our overall business. In addition, our competitors could have, obtain or assert intellectual property rights that could affect or restrict our ability to market our existing products and/or to innovate and develop new products, thus increasing our costs of doing business, could attempt to introduce products similar to ours following the expiration of our patents, or could attempt to introduce products that do not fall within the scope of our intellectual property rights.
WE ARE SUBJECT TO RISKS ASSOCIATED WITH OUR INTERNATIONAL OPERATIONS
We currently have operations and a large customer base outside the U.S. Approximately 65% of our revenue was generated by sales to customers outside the U.S. for the fiscal year ended September 30, 2020. We may encounter risks in doing business in certain countries other than the U.S., including, but not limited to, adverse changes in economic and political conditions, both in foreign locations and in the U.S. with respect to non-U.S. operations of U.S. businesses like ours, geopolitical and/or trade tensions, global health crises such as the ongoing Pandemic, civil unrest, fluctuation in exchange rates, changes in international trade requirements and sanctions and/or tariffs that affect our business and that of our customers and suppliers, compliance with a variety of foreign laws and regulations and related audits and investigations, as well as difficulty in enforcing business and customer contracts and agreements, including protection of intellectual property rights. We also may encounter risks that we may not be able to repatriate additional earnings from our operations outside of the U.S., derive anticipated tax benefits of these operations or recover the investments made in them, whether due to regulatory or policy changes in the U.S. or in the countries outside of the U.S. in which we do business, or other factors.
In particular, China continues to be an important market for the semiconductor industry, and an area of continued potential growth for us. As business between China and the rest of the world has continued to grow, there is risk that geopolitical, regulatory, trade, political and global public health crises such as the Pandemic could adversely affect business for companies like ours based on the complex relationships among China, the U.S., and other countries in the Asia Pacific region or elsewhere, which could have a material adverse impact on our business. In addition, there are risks that the Chinese government may, among other things, require the use of local suppliers, compel companies that do business in China to partner with local companies to conduct business, or, provide incentives to government-backed local customers to buy from local suppliers rather than companies like ours, all of which could adversely impact our business, including our results of operations. Also, as has been seen over our last fiscal year and through the first half of fiscal 2021, there are risks that the U.S. government may impose additional export restrictions on technology and products that companies that operate in the semiconductor industry supply to or use in China, which could adversely impact our business and our results of operations.
In addition, we have operations and customers located in the United Kingdom, which recently has exited the European Union (“EU”). As the transitional provisions under which the United Kingdom and the EU have agreed to operate expired at the end of December 2020, and the parties are still in the process of implementing new trade agreements, the related impacts on our business remain unclear.
36

INDEX
LEGAL, COMPLIANCE AND REGULATORY RISKS
WE ARE SUBJECT TO EXTENSIVE ENVIRONMENTAL LAWS AND REGULATIONS AND MAY INCUR COSTS THAT HAVE AN ADVERSE EFFECT ON OUR FINANCIAL CONDITION AS A RESULT OF VIOLATIONS OF OR LIABILITIES UNDER THEM
Like other companies involved in environmentally sensitive businesses, our operations and properties are subject to extensive and stringent federal, state, local and foreign Environmental, Health and Safety (“ EHS”) laws and regulations, including those concerning, among other things:
•    the marketing, sale, use and registration of our chemical products, such as penta, which is part of the wood treatment business in our Performance Materials segment;
•    the treatment, storage and disposal of wastes;
•    the investigation and remediation of contaminated media including but not limited to soil and groundwater;
•    the discharge of effluents into waterways;
•    the emission of substances into the air; and
•    other matters relating to environmental protection and various health and safety matters.
The United States EPA and other federal and state agencies in the U.S., as well as comparable agencies in other countries where we have facilities or sell our products, such as Canada or Mexico, have the authority to promulgate regulations that could have a material adverse impact on our operations. These EHS laws and regulations may require permits for certain types of operations, require the installation of expensive pollution control equipment, place restrictions upon operations or impose substantial liability for pollution and other EHS concerns resulting from our operations. Compliance with EHS laws and regulations has resulted in ongoing costs for us and could restrict our ability to modify or expand our facilities, continue production, require us to install costly pollution control equipment, or incur significant other expenses, including environmental compliance costs. We continue to manage environmental compliance activities at certain sites, such as at KMG-Bernuth's Tuscaloosa, Alabama facility as described in Note 20 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. We have incurred, and expect to continue to incur, significant costs to comply with EHS laws or to address liabilities for contamination resulting from past or present operations. Federal, state and foreign governmental authorities may seek fines and penalties, as well as injunctive relief, for violation of EHS laws and regulations, and could, among other things, impose liability on us to cleanup or mitigate environmental, natural resources or other damages resulting from a release of pesticides, hazardous materials or other chemicals into the environment. We maintain insurance coverage for sudden and accidental environmental damages. We do not believe that insurance coverage for environmental damage that occurs over time is available at a reasonable cost. Also, we do not believe that insurance coverage for the full potential liability that could be caused by sudden and accidental incidences is available at a reasonable cost. Accordingly, we may be subject to an uninsured or under-insured loss in such cases; although unknown at present, the KMG-Bernuth warehouse fire, as described in Note 12 of Part 1 of this Report on Form 10-Q, may be such an instance.
The distribution, sale and use of our products is subject to prior governmental approvals and thereafter ongoing governmental regulation: Our products are subject to laws administered by federal, state and foreign governments, including regulations requiring registration, approval and labeling. The labeling requirements restrict the use and type of application for our products. More stringent restrictions could make our products less desirable which would adversely affect our sales and profitability. All venues where our penta products are used also require registration prior to marketing or use.
Governmental regulatory authorities have required, and may require in the future, that certain scientific testing and data production be provided on our products. Under the Federal Insecticide, Fungicide and Rodenticide Act (“FIFRA”), the EPA requires registrants to submit a wide range of scientific data to support U.S. registrations. This requirement significantly increases our Operating expenses, and we expect those expenses will continue in the future while we operate the wood treatment business. Because scientific analyses are constantly improving, we cannot determine with certainty whether or not new or additional tests may be required by regulatory authorities. While good laboratory practice standards specify the minimum practices and procedures that must be followed in order to ensure the quality and integrity of data related to these tests submitted to the EPA, there can be no assurance that the EPA will not request certain tests or studies be repeated. In addition, more stringent legislation or requirements may be imposed in the future. Amendments to the Toxic Substances Control Act could result in increased regulation and required testing of chemicals we manufacture and could increase the costs of compliance for our operations. We can provide no assurance that the cost of such compliance will not adversely affect our profitability. Our products could also be subject to other future regulatory action that may result in restricting or completely banning their use which could have an adverse effect on our performance and results of operations.
37

INDEX
1. The Registration, Evaluation and Authorization of Chemicals (“REACH”) legislation may affect our ability to manufacture and sell certain products in the EU: REACH requires chemical manufacturers and importers in the EU to prove the safety of their products. We were required to pre-register certain products and file comprehensive reports, including testing data, on each chemical substance, and perform chemical safety assessments. Additionally, substances of high concern are subject to an authorization process. Authorization may result in restrictions on certain uses of products or even prohibitions on the manufacture or importation of products. The full registration requirements of REACH have been phased in over several years, and we have incurred additional expense to cause the registration of our products under these regulations. REACH may also affect our ability to import, manufacture and sell certain products in the EU. In addition, other countries and regions of the world already have or may adopt legislation similar to REACH that affect our business, affect our ability to import, manufacture or sell certain products in these jurisdictions, and have required or will require us to incur increased costs.
2. The classification of penta as a Persistent Organic Pollutant (“POP”) under the Stockholm Convention may adversely affect our ability to manufacture or sell our penta products: The Conference of the Parties (“COP”) accepted the recommendation of the United Nations Persistent Organic Pollutant Review Committee that the use of penta should be banned except that its use for the treatment of utility poles and crossarms could continue for an extended period of five to ten years. KMG-Bernuth supplies penta to industrial customers who use it primarily to treat utility poles and crossarms. The U.S. is not bound by the determination of the COP because it did not ratify the Stockholm Convention treaty. Canada and Mexico are governed by the treaty. KMG-Bernuth's sole penta manufacturing facility is located in Matamoros, Mexico, and its processing facility is located in Tuscaloosa, Alabama. As a result of the classification of penta as a POP, the Mexican government requires KMG-Bernuth to cease producing penta in Mexico by the end of calendar year 2021. In July 2020, the Canadian government released a proposed order that sales and use of penta in Canada be ceased, but such proposed order is subject to a comment period and is not final, and no timing for any such order, if implemented, has been proposed. In March 2021, the EPA issued a preliminary interim registration review decision(“PID”) proposing the cancellation of penta registration and implementation of a five-year phase-out period for production and sell-through of penta stocks. We do not believe the PID or the Canadian government proposed order have a significant adverse effect on our business since in July 2019, KMG-Bernuth had communicated plans to close both the Matamoros and Tuscaloosa facilities by the end of calendar year 2021 and in November 2019, we communicated that we did not intend to continue the wood treatment business past approximately the end of calendar year 2021. We took a restructuring charge in our fourth fiscal quarter of 2019, and asset impairment charges in each of our fourth fiscal quarters of 2020 and 2019, as well as our first two fiscal quarters of fiscal 2021, related to the decisions to close the Matamoros and Tuscaloosa facilities and to not build a new plant,as described further in Note 7 of Part 1 of this Report on Form 10-Q. We expect to take additional impairment charges related to the wood treatment business through the end of calendar year 2021. No assurance can be given that we will not incur significant expenditures in connection with closing the facilities, or that the ultimate action of the COP and our related decisions will not adversely impact on our financial condition and results of operation.
3. Our use of hazardous materials exposes us to potential liabilities: Our manufacturing and distribution of chemical products, such as our electronic chemicals, involves the controlled use of hazardous materials. Our operations, therefore, are subject to various associated risks, including chemical spills, discharges or releases of toxic or hazardous substances or gases, fires, mechanical failure, storage facility leaks and similar events. Our suppliers are subject to similar risks that may adversely impact the availability of raw materials. While we adapt our manufacturing and distribution processes to the environmental control standards of regulatory authorities, we cannot completely eliminate the risk of accidental contamination or injury from hazardous or regulated materials, including injury of our employees, individuals who handle our products or goods treated with our products, or others who claim to have been exposed to our products, nor can we completely eliminate the unanticipated interruption or suspension of operations at our facilities due to such events. We may be held liable for significant damages or fines in the event of contamination or injury, and such assessed damages or fines could have an adverse effect on our financial performance and results of operations.
CURRENT OR FUTURE CLIMATE CHANGE REGULATIONS COULD RESULT IN INCREASED OPERATING COSTS AND REDUCED DEMAND FOR OUR PRODUCTS
The U.S. has recently rejoined the Paris Climate Accord but to date, has not ratified the Kyoto Protocol. The Clean Air Act has been interpreted to regulate greenhouse gas (“GHG”) emissions and the EPA is using its existing regulatory authority to develop regulations requiring reduction in GHG emissions from various categories of sources, such as when a permit is required due to emissions of other pollutants. Because of the lack of any comprehensive legislation program addressing GHGs, a number of U.S. federal laws related to GHG emissions have been considered by the U.S. Congress from time to time and various state, local and regional regulations and initiatives have been enacted or are being considered related to GHGs.
38

INDEX
Member States of the EU each have an overall cap on emissions, which are approved by the European Commission, and implement the EU Emissions Trading Directive as a commitment to the Kyoto Protocol. GHG emissions are regulated by Member States through the EU Emission Trading System and the EU Effort Sharing Decision/Regulation depending upon the industry sector. Organizations apply to the Member State for an allowance of GHG emissions. These allowances are tradable so as to enable companies that manage to reduce their GHG emissions to sell their excess allowances to companies that are not reaching their emissions objectives. Failure to purchase sufficient allowances will require the purchase of allowances at a current market price.
Any laws or regulations that may be adopted to restrict or reduce emissions of GHGs could cause an increase to our raw material costs, require us to incur increased operating costs, and have an adverse effect on demand for our products and our financial performance and results for our business.
In addition to GHG and climate change regulatory developments and legislation, we are continuing to evaluate and assess the potential impact on our business of the ongoing transition worldwide to a low carbon, resilient economy as well as physical effects resulting from climate change.
OUR PRODUCTS MAY BE RENDERED OBSOLETE OR LESS ATTRACTIVE BY CHANGES IN INDUSTRY REQUIREMENTS OR BY SUPPLY-CHAIN DRIVEN PRESSURES TO SHIFT TO ENVIRONMENTALLY PREFERABLE ALTERNATIVES
Changes in regulatory, legislative and industry requirements, or changes driven by supply-chain pressures, may shift current customers away from products using penta, products containing hazardous materials, or certain of our other products and toward alternative products that are believed to have fewer environmental effects. The EPA, foreign and state regulators, local governments, private environmental advocacy organizations, investors and investor advisory firms, and a number of large industrial companies have proposed or adopted policies designed to decrease the use of a variety of chemicals, including penta and others included in certain of our products, such as those containing hazardous materials, or to counteract the growth of certain industries such as those in which customers served by our PIM products operate. Our ability to anticipate changes in regulatory, legislative, investor, and industry requirements, or changes driven by supply-chain pressures, affects our ability to remain competitive. Further, we may not be able to comply with changed or new regulatory or industrial standards that may be necessary for us to remain competitive.
We cannot assure you that the EPA, foreign and state regulators or local governments will not restrict the uses of penta or certain of our other products or ban the use of one or more of these products or the raw materials in them. Similarly, companies who use our products may decide to reduce significantly or cease the use of our products voluntarily. As a result, our products may become obsolete or less attractive to our customers.

GENERAL COMMERCIAL, OPERATIONAL, FINANCIAL AND REGULATORY RISKS
BECAUSE WE RELY ON OUR INTELLECTUAL PROPERTY, OUR FAILURE TO ADEQUATELY OBTAIN OR PROTECT IT COULD SIGNIFICANTLY HARM OUR BUSINESS
Protection of intellectual property is particularly important in the semiconductor industry, which is the primary industry in which we participate, because we develop complex technical formulas and processes for products that are proprietary in nature and differentiate our products from those of our competitors. Our intellectual property is important to our success and ability to compete. We attempt to protect our intellectual property rights through a combination of patent, trademark, copyright and trade secret laws, as well as employee and third-party nondisclosure and assignment agreements. In addition, we protect our product differentiation through various other means, such as proprietary supply arrangements for certain raw materials, and use of certain manufacturing technologies. Due to our international operations, we pursue protection in different jurisdictions, which may provide varying degrees of protection, and we cannot provide assurance that we can obtain adequate protection in each such jurisdiction. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason, including through the patent prosecution process or in the event of litigation related to such intellectual property, which we pursue when necessary to protect our rights against others who are found to be misusing our intellectual property, could seriously harm our business. In addition, certain types of intellectual property, such as patents, expire after a certain period of time, and products protected by our patents then lose such protection, so we refresh our intellectual property portfolio on an ongoing basis through continued innovation, and failure to do so could adversely affect our business. Also, the costs of obtaining or protecting our intellectual property could negatively affect our operating results.

OUR INABILITY TO ATTRACT AND RETAIN KEY PERSONNEL COULD CAUSE OUR BUSINESS TO SUFFER
We utilize and rely upon a global workforce. If we fail to attract and retain the necessary managerial, technical and customer support personnel, our business and our ability to maintain existing and obtain new customers, develop new products and provide acceptable levels of customer service could suffer. We compete worldwide with other participants in the industries in which we do business for qualified personnel, particularly those with significant experience in the semiconductor and pipeline industries. The loss of services of key employees, or our inability to obtain or maintain visas or other travel or residency documents on their behalf with respect to our business needs, could harm our business and results of operations. Periodically, we engage in succession planning for our key employees, and our Board of Directors reviews succession planning for our executive officers, including our chief executive officer, on an annual basis.
BECAUSE WE HAVE LIMITED EXPERIENCE IN BUSINESS AREAS OUTSIDE OF ELECTRONIC MATERIALS AND PERFORMANCE MATERIALS, EXPANSION OF OUR BUSINESS INTO OTHER PRODUCTS AND APPLICATIONS MAY NOT BE SUCCESSFUL
An element of our strategy has been to leverage our customer relationships, technological expertise and other capabilities and competencies to expand our business. For example, we have made acquisitions to expand beyond CMP consumables into other electronic materials product areas, as well as into performance materials product areas in which we have limited experience. Expanding our business into new product areas could involve technologies, production processes and business models in which we have limited experience, and we may not be able to develop and produce products or provide services that satisfy customers' needs, or we may be unable to keep pace with technological or other developments. Or, we may decide that we no longer wish to pursue these new business initiatives. Also, our competitors may have or obtain intellectual property rights that could restrict our ability to market our existing products and/or to innovate and develop new products.
TAX INCREASES OR CHANGES IN TAX RULES MAY ADVERSELY AFFECT OUR FINANCIAL RESULTS
As a company conducting business on a global basis, we are exposed, both directly and indirectly, to effects of changes in U.S., state, local and foreign tax rules. In December 2017, comprehensive tax legislation was enacted in the U.S. under the Tax Act. Known and certain estimated effects based upon current interpretation of the Tax Act have been incorporated into our financial results. Adjustments to income tax amounts could be material to our results of operations and cash flows. In addition, there is a risk that the U.S. state or foreign jurisdictions may amend their tax laws, including the Tax Act or otherwise, which could have a material impact on our future results of operations and cash flows.
CERTAIN CRITICAL INFORMATION SYSTEMS COULD BE SUSCEPTIBLE TO CYBERSECURITY AND OTHER THREATS
We maintain and rely upon certain critical information systems for the effective operation of our business. These information systems include, but are not limited to, telecommunications, the Internet, our corporate intranet, various computer hardware and software applications, network communications, and email. These information systems may be owned and maintained by us, our outsourced providers, or third parties such as vendors, contractors, and Cloud providers. All these information systems are subject to disruption, breach or failure from various sources including, but not limited to, attacks, degradation, and failures resulting from potential sources, including viruses, malware, denial of service, destructive or inadequate code, power failures, and physical damage. Confidential and/or sensitive information stored on these information systems, or transmitted to or from Cloud storage, could be intentionally or unintentionally compromised, lost, and/or stolen. While we have implemented security procedures and virus protection software, intrusion prevention systems, access control, and emergency recovery processes to mitigate risks like these with respect to information systems that are under our control, they are not fail-safe and may be subject to breaches. Further, we cannot assure that third parties upon whom we rely for various IT services will maintain sufficient vigilance and controls over their systems. Our inability to use or access these information systems at critical points in time, or unauthorized releases of personal or confidential information, could unfavorably impact the timely and efficient operation of our business, including our results of operations, and our reputation, as well as our relationships with our employees or other individuals whose information may have been affected by such cybersecurity incidents.
In addition, regulatory authorities have increased their focus on how companies collect, process, use, store, share and transmit personal data. Privacy security laws and regulations, including the United Kingdom's Data Protection Act 2018 and the EU General Data Protection Regulation 2016, and similar laws in countries such as Korea and Taiwan, among others, pose increasingly complex compliance challenges, which may increase compliance costs, and any failure to comply with data privacy laws and regulations could result in significant penalties that could adversely affect our business and results of operations.

OUR ABILITY TO RAISE CAPITAL IN THE FUTURE MAY BE LIMITED, WHICH COULD PREVENT US FROM GROWING, AND OUR EXISTING CREDIT AGREEMENT COULD RESTRICT OUR BUSINESS ACTIVITIES
In the future we may be required to raise capital through public or private financing or other arrangements. Such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business. Our Amended Credit Agreement contains financial and other covenants that may restrict our business activities or our ability to execute our strategic objectives, and our failure to comply with these covenants could result in a default under it. Furthermore, additional equity financing may dilute the interests of our common stockholders, and debt financing, if available, may involve restrictive covenants that could further restrict our business activities or our ability to execute our strategic objectives and could reduce our profitability. If we raise or borrow funds on acceptable terms, we may not be able to grow our business or respond to competitive pressures.
In addition, borrowings under our Amended Credit Agreement generally bear interest based on (a) a LIBOR, subject to a 0.00% floor, or (b) a base rate in each case, plus an applicable margin of, in the case of borrowings under the Term Loan Facility, 2.00% for LIBOR loans and 1.00% for base rate loans and, in the case of borrowings under the Revolving Credit Facility, initially, 1.50% for LIBOR loans and 0.50% for base rate loans. On July 27, 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. In the U.S., the Alternative Reference Rates Committee, the working group formed to recommend an alternative rate to LIBOR, has identified the Secured Overnight Financing Rate as its preferred alternative rate for USD LIBOR. When LIBOR ceases to exist after 2021, any calculation of interest based upon the Alternate Base Rate (or any comparable or replacement formulation), may result in higher interest rates. To the extent that these interest rates increase, our Interest expense will increase, which could adversely affect our financial condition, operating results and cash flows.
THE MARKET PRICE FOR OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY AND RAPIDLY
The market price of our common stock has fluctuated and could continue to fluctuate significantly as a result of factors such as: economic, geopolitical, global public health (i.e., the Pandemic), political and stock market conditions generally and specifically as they may impact participants in the semiconductor and related industries; and/or participants in oil and gas related industries; changes in financial estimates and recommendations by securities analysts who follow our stock; earnings and other announcements, and changes in market evaluations, by securities analysts, investors, market participants or others, of or related to, us or participants in the semiconductor and related industries; changes in business, trade or regulatory conditions affecting us or participants in the semiconductor and related industries; announcements or implementation by us, our competitors, or our customers of technological innovations, new products or different business strategies; changes in our capital deployment strategy, issuances of shares of our capital stock or entering into a business combination or other strategic transaction; and trading volume of our common stock.
ANTI-TAKEOVER PROVISIONS UNDER OUR CERTIFICATE OF INCORPORATION AND BYLAWS MAY DISCOURAGE THIRD PARTIES FROM MAKING AN UNSOLICITED BID FOR OUR COMPANY
Our certificate of incorporation and bylaws, and various provisions of the Delaware General Corporation Law may make it more difficult or expensive to effect a change in control of our Company. For instance, our amended and restated certificate of incorporation provides for the division of our Board of Directors into three classes as nearly equal in size as possible with staggered three-year terms.
We have adopted change in control arrangements covering our executive officers and other key employees. These arrangements provide for a cash severance payment, continued medical benefits and other ancillary payments and benefits upon termination of service of a covered employee's employment following a change in control, which may make it more expensive to acquire our Company.
