NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions, except per share data)

1)	Basis of Presentation

The terms “MKS” and the “Company” refer to MKS Instruments, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The interim financial data as of September 30, 2021, and for the three and nine months ended September 30, 2021 are unaudited; however, in the opinion of MKS, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The condensed consolidated balance sheet presented as of December 31, 2020 has been derived from the consolidated audited financial statements as of that date. The unaudited condensed consolidated financial statements presented herein have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and note disclosures required by United States generally accepted accounting principles (“U.S. GAAP”). The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the MKS Annual Report on Form 10-K for the year ended December 31, 2020 filed with the U.S. Securities and Exchange Commission on February 23, 2021.

The preparation of these unaudited condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments, including those related to revenue recognition, inventory valuation, warranty costs, stock-based compensation, intangible assets, goodwill, other long-lived assets and other acquisition expenses and income taxes. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

2)	Recently Issued or Adopted Accounting Pronouncements

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU No. 2021-08"). ASU No. 2021-08 will require companies to apply the definition of a performance obligation under ASC Topic 606 to recognize and measure contract assets and contract liabilities (i.e., deferred revenue) relating to contracts with customers that are acquired in a business combination. Under current U.S. GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC Topic 606. ASU No. 2021-08 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact of this ASU on its financial statements.

In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This standard provides temporary optional expedients and exceptions to accounting guidance on contract modifications and hedge accounting to ease entities’ financial reporting burdens as the market transitions from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The standard was effective upon issuance and generally can be applied through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” The amendments in this update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments in this update to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments in this update do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and existing hedging relationships evaluated for effectiveness in periods after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022). The Company’s adoption of the requirements of these standards has not resulted in a material impact on its financial position, results of operations and cash flows, but the adoption of the requirements may impact the Company in the future.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740).” This standard simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions, except per share data)

application and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This standard is effective for annual periods, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this ASU during the first quarter of 2021 and the adoption of this ASU did not have a material impact on its financial position, results of operations and cash flows.

3)	Revenue from Contracts with Customers

Management has the ability to liquidate its investments in order to meet the Company’s liquidity needs in the next 12 months. Accordingly, those investments with contractual maturities greater than one year from the date of purchase are classified as short-term on the accompanying balance sheets.

Interest income is accrued as earned. Dividend income is recognized as income on the date the security trades “ex-dividend.” The cost of marketable securities sold is determined by the specific identification method. Realized gains or losses are reflected in income and were not material for the three and nine months ended September 30, 2021 and 2020.

5)	Fair Value Measurements

In accordance with the provisions of fair value accounting, a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.

The fair value measurement guidance establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:

Level 1

Quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2

Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments or securities or derivative contracts that are valued using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data.

Level 3

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the Company categorizes such assets and liabilities based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Money Market Funds

Available-For-Sale Investments

The Company measures its debt and equity investments at fair value. The Company’s available-for-sale investments are classified within Level 2 of the fair value hierarchy.

MKS INSTRUMENTS, INC.

(in millions, except per share data)

Israeli Pension Assets

Israeli pension assets represent investments in mutual funds, government securities and other time deposits. These investments are set aside for the retirement benefit of the employees of the Company’s Israeli subsidiaries. These funds are classified within Level 2 of the fair value hierarchy.

Derivatives

As a result of the Company’s global operating activities, the Company is exposed to market risks from changes in foreign currency exchange rates and variable interest rates, which may adversely affect its operating results and financial position. When deemed appropriate, the Company minimizes its risks from foreign currency exchange rate and interest rate fluctuations through the use of derivative financial instruments. The principal market in which the Company executes its foreign currency contracts and interest rate swaps is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants are typically large commercial banks. The foreign exchange forward contracts and interest rate hedges are valued using broker quotations or market transactions and are classified within Level 2 of the fair value hierarchy.

6)	Derivatives

The Company enters into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments and those utilized as economic hedges. The Company operates internationally and, in the normal course of business, is exposed to fluctuations in interest rates and foreign exchange rates. These fluctuations can increase the costs of financing, investing and operating the business. The Company has used derivative instruments, such as foreign exchange forward contracts, to manage certain foreign currency exposure, and interest rate swaps to manage interest rate exposure.

By nature, all financial instruments involve market and credit risks. The Company enters into derivative instruments with major investment grade financial institutions, for which no collateral is required. The Company has policies to monitor the credit risk of these counterparties. While there can be no assurance, the Company does not anticipate any material non-performance by any of these counterparties.

Foreign Exchange Forward Contracts

The Company hedges a portion of its forecasted foreign currency-denominated intercompany sales of inventory, over a maximum period of eighteen months, using foreign exchange forward contracts accounted for as cash-flow hedges related to British, Euro, Japanese, South Korean and Taiwanese currencies. To the extent these derivatives are effective in off-setting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives’ fair value are not included in current earnings but are included in other comprehensive income (“OCI”) in stockholders’ equity. These changes in fair value will subsequently be reclassified into earnings, as applicable, when the forecasted transaction occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. The cash flows resulting from foreign exchange forward contracts are classified in the condensed consolidated statements of cash flows as part of cash flows from operating activities. The Company does not enter into derivative instruments for trading or speculative purposes.

In conjunction with the acquisition of Photon Control Inc., a Canada corporation (“Photon Control”), which closed in July 2021, the Company entered into a foreign currency contract to hedge the Canadian dollar purchase price. For the three and nine months ended September 30, 2021, the Company recorded a fair value loss of $2.8 and $10.3, respectively, which is included in other expense, net.

Interest Rate Swap Agreements

The Company entered into various interest rate swap agreements that exchange the variable LIBOR interest rate to a fixed rate in order to manage the exposure to interest rate fluctuations associated with the variable LIBOR interest rate paid on the outstanding balance of the Term Loan Facility, as defined and further described in Note 10. The table below summarizes the various interest rate hedges entered into by the Company:

									September 30, 2021		September 30, 2021			December 31, 2020

									Total		$	(3.8	)	$	(14.0	)

The interest rate swaps are recorded at fair value on the balance sheet and changes in the fair value are recognized in OCI. To the extent that these arrangements are no longer effective hedges, any ineffectiveness measured in the hedging relationships is recorded immediately in earnings in the period it occurs.

Leases

The Company has various operating leases for real estate and non-real estate items. The non-real estate leases are mainly comprised of automobiles but also include office equipment and other lower-valued items. The Company does not have any finance leases. As most of the Company’s leases do not provide an implicit rate, an incremental borrowing rate is used based

MKS INSTRUMENTS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions, except per share data)

on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date.

Some of the Company’s real estate lease agreements include Company options to either extend and/or terminate the lease. The cost of these options is included in our operating lease liabilities to the extent that such options are reasonably certain of being exercised. Leases with renewal options allow the Company to extend the lease term typically between 1 to 10 years. When determining the lease term, renewal options reasonably certain of being exercised are included in the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements made to the property, whether the physical space is difficult to replace, underlying contractual obligations, and specific characteristics unique to that particular lease that would make it reasonably certain that the Company would exercise such an option.

The Company has existing leases that include variable lease and non-lease components that are not included in the right-of-use asset and lease liability and are reflected as expenses in the periods incurred. Such payments primarily include common area maintenance charges and increases in rent payments that are driven by factors such as future changes in an index (e.g., the Consumer Price Index).

The elements of lease expense were as follows:

	Three Months Ended September 30,
	2021		2020
Lease cost:
Operating lease cost⁽¹⁾	$	6.6	$	7.2
Short-term lease		1.2		1.4

Operating lease cost⁽¹⁾	$	20.7	$	22.1
Short-term lease		3.4		3.7
Total lease cost	$	24.1	$	25.8

⁽¹⁾

Operating lease cost includes an immaterial amount of variable expenses and sublease rental income.

The weighted average discount rate and the weighted average remaining lease term were 2.9% and 14.4 years, respectively, as of September 30, 2021. The weighted average discount rate and weighted average remaining lease term were 3.0% and 15.0 years, respectively, as of September 30, 2020. Operating cash flows used for operating leases for the nine months ended September 30, 2021 and 2020 were $11.6 and $15.4, respectively. Operating cash flows used for operating leases for the nine months ended September 30, 2021 of $11.6 was net of $5.0 in tenant improvement allowance receipts.

Future lease payments under non-cancelable leases as of September 30, 2021 are detailed as follows:

2021 (remaining)	$	4.8

9)	Goodwill and Intangible Assets

Goodwill

The Company’s methodology for allocating the purchase price relating to purchase acquisitions is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the cost of the acquisition over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed. The Company assigns assets acquired (including goodwill) and liabilities assumed to one or more reporting units as of the date of acquisition. Typically acquisitions relate to a single reporting unit and thus do not require the allocation of goodwill to multiple reporting units. If the products obtained in an acquisition are assigned to multiple reporting units, the goodwill is distributed to the respective reporting units as part of the purchase price allocation process.

Goodwill and purchased intangible assets with indefinite useful lives are not amortized but are reviewed for impairment annually during the fourth quarter of each fiscal year and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The process of evaluating the potential impairment of goodwill and intangible assets requires significant judgment. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends, restructuring actions and lower projections of profitability that may impact future operating results.

The changes in the carrying amount of goodwill and accumulated impairment loss during the nine months ended September 30, 2021 and year ended December 31, 2020 were as follows:

	Nine Months Ended September 30, 2021									Twelve Months Ended December 31, 2020
	Gross Carrying Amount			Accumulated Impairment Loss			Net			Gross Carrying Amount		Accumulated Impairment Loss			Net
Beginning balance at January 1	$	1,211.8		$	(145.4	)	$	1,066.4		$	1,202.8	$	(144.3	)	$	1,058.5

The Term Loan Facility is subject to increase at the Company’s option and subject to receipt of lender commitments in accordance with the Term Loan Credit Agreement. The maturity date of the Term Loan Facility is February 2, 2026. As of September 30, 2021, borrowings under the Term Loan Facility bear interest per annum at one of the following rates selected by the Company: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%, and (4) a floor of 1.00%, plus, in each case, an applicable margin of 0.75%; or (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, subject to a LIBOR rate floor of 0.0%, plus an applicable margin of 1.75%. The Company has elected the interest rate as described in clause (b) of the foregoing sentence. The Term Loan Credit Agreement provides that, unless an alternate rate of interest is agreed, all loans will be determined by reference to the base rate if the LIBOR rate cannot be ascertained, if regulators impose material restrictions on the authority of a lender to make LIBOR rate loans, or for other reasons.

In May 2021, the Company entered into an amendment (the “May Term Loan Amendment”) to the Term Loan Credit Agreement. The May Term Loan Amendment amends the Term Loan Facility to, among other things, (i) increase the Company’s ability to incur additional incremental debt facilities to (x) the greater of (1) $600.0 and (2) 100% of consolidated EBITDA, plus (y) an amount equal to the sum of all voluntary prepayments of term loans under the Term Loan Facility, plus (z) an additional unlimited amount subject to pro forma compliance with a secured leverage ratio test of 3.25:1.00, and (ii) increase the Company’s flexibility under certain debt, lien, investment, restricted payment and disposition baskets. The fees incurred, including certain customary lender consent fees, in connection with the May Term Loan Amendment were immaterial.

As of September 30, 2021, the Company has incurred an aggregate amount of $42.6 of deferred finance fees, original issue discount and repricing fees related to the term loans under the Term Loan Facility, which are included in long-term debt in the accompanying condensed consolidated balance sheets and are being amortized to interest expense over the estimated life of the term loans using the effective interest method. As of September 30, 2021, the remaining balance of deferred finance fees, original issue discount and repricing fees related to the term loans under the Term Loan Facility was $8.0. A portion of the deferred finance fees, original issue discount and repricing fees have been accelerated in connection with the various debt prepayments and amendments between 2016 and 2021.

The Company is required to make scheduled quarterly amortization payments each equal to 0.25% of the original principal amount of the Term Loan Facility.

As of September 30, 2021, after giving effect to all amendments and repayments prior to such date, the outstanding principal amount of the Term Loan Facility was $826.7, and the interest rate was 1.8%.

Under the Term Loan Credit Agreement, the Company is required to prepay outstanding term loans, subject to certain exceptions, with portions of its annual excess cash flow as well as with the net cash proceeds of certain of its asset sales, certain casualty and condemnation events and the incurrence or issuance of certain debt.

All obligations under the Term Loan Facility are guaranteed by certain of the Company’s domestic subsidiaries and are secured by substantially all of the Company’s assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

The Term Loan Credit Agreement contains customary representations and warranties, affirmative and negative covenants and provisions relating to events of default. If an event of default occurs, the lenders under the Term Loan Facility will be entitled to take various actions, including the acceleration of amounts due under the Term Loan Facility and all actions generally permitted to be taken by a secured creditor. At September 30, 2021, the Company was in compliance with all covenants under the Term Loan Credit Agreement.

Interest Rate Swap Agreements

The Company entered into various interest rate swap agreements as described further in Note 6 that exchange the variable LIBOR interest rate to a fixed rate in order to manage the exposure to interest rate fluctuations associated with the variable LIBOR interest rate paid on the outstanding balance of the Term Loan Facility.

Senior Secured Asset-Based Revolving Credit Facility

In February 2019, in connection with the completion of the acquisition of Electro Scientific Industries, Inc. (the “ESI Merger”), the Company entered into an asset-based revolving credit agreement with Barclays Bank PLC, as administrative agent and collateral agent, the other borrowers from time to time party thereto, and the lenders and letters of credit issuers from time to time party thereto (the “ABL Credit Agreement”), that provides a senior secured asset-based revolving credit facility of up to $100.0, subject to a borrowing base limitation (the “ABL Facility”). The Company has entered into two amendments to the ABL Credit Agreement since 2019. As of September 30, 2021, after giving effect to all amendments, the borrowing base for the ABL Facility at any time equals the sum of: (a) 85% of certain eligible accounts; plus (b) prior to certain notice and field examination and appraisal requirements, the lesser of (i) 20% of net book value of eligible inventory in the United States and (ii) 30% of the borrowing base, and after the satisfaction of such requirements, the lesser of (i) the lesser of (A) 65% of the lower of cost or market value of certain eligible inventory and (B) 85% of the net orderly liquidation value of certain eligible inventory and (ii) 30% of the borrowing base; minus (c) reserves established by the administrative agent, in each case, subject to additional limitations and examination requirements for eligible accounts and eligible inventory acquired in an acquisition after February 1, 2019. The ABL Facility includes borrowing capacity in the form of letters of credit up to $25.0. The Company has not borrowed against the ABL Facility to date.

As of September 30, 2021, borrowings under the ABL Facility bear interest at a rate per annum equal to, at the Company’s option, any of the following, plus, in each case, an applicable margin: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00% and (4) a floor of 0.00%, plus, in each case, an applicable margin ranging from 0.25% to 0.50%; and (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, with a floor of 0.00%, plus, in each case, an applicable margin ranging from 1.25% to 1.50%. The applicable margin for borrowings thereunder is subject to upward or downward adjustment each fiscal quarter, based on the average historical excess availability during the preceding quarter.

In addition to paying interest on any outstanding principal under the ABL Facility, the Company is required to pay a commitment fee in respect of the unutilized commitments thereunder equal to 0.25% per annum. The Company must also pay customary letter of credit fees and agency fees.

Under the ABL Facility, the Company is required to prepay amounts outstanding under the ABL Facility (1) if amounts outstanding under the ABL Facility exceed the lesser of (a) the commitment amount and (b) the borrowing base, in an amount required to reduce such shortfall, (2) if amounts outstanding under the ABL Facility in any currency other than U.S. dollars exceed the sublimit for such currency, in an amount required to reduce such shortfall, and (3) during any period in which the Company has excess availability less than the greater of (a) 10.0% of the lesser of (x) the commitment amount and (y) the borrowing base (the “Line Cap”) and (b) $8.5 for 3 consecutive business days, until the time when the Company has excess availability equal to or greater than the greater of (A) 10.0% of the Line Cap and (B) $8.5 for 30 consecutive days, or during the continuance of an event of default, with immediately available funds in its blocked accounts.

There is no scheduled amortization under the ABL Facility. Any principal amount outstanding under the ABL Facility is due and payable in full on the fifth anniversary of the closing date, subject to a springing maturity in the event that term loans under the Term Loan Facility in an aggregate amount of at least $100.0 have an earlier maturity date than the ABL Facility.

All obligations under the ABL Facility are guaranteed by certain of the Company’s domestic subsidiaries and are secured by substantially all of the Company’s assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

From the time when the Company has excess availability less than the greater of (a) 10.0% of the Line Cap and (b) $8.5 until the time when the Company has excess availability equal to or greater than the greater of (a) 10.0% of the Line Cap and (b) $8.5 for 30 consecutive days, or during the continuance of an event of default, the ABL Credit Agreement requires the Company to maintain a fixed charge coverage ratio, tested on the last day of each fiscal quarter, of at least 1.0 to 1.0.

The ABL Credit Agreement also contains customary representations and warranties, affirmative covenants and provisions relating to events of default. If an event of default occurs, the lenders under the ABL Facility will be entitled to take various actions, including the acceleration of amounts due under the ABL Facility and all actions permitted to be taken by a secured creditor.

Lines of Credit and Borrowing Arrangements

The Company’s Japanese subsidiaries have lines of credit and a financing facility with various financial institutions, many of which generally expire and are renewed at three-month intervals with the remaining having no expiration date. The lines of credit and financing facility provided for aggregate borrowings as of September 30, 2021 of up to an equivalent of $29.9. There were no borrowings outstanding under these arrangements at September 30, 2021. Total borrowings outstanding under these arrangements were $5.5 at December 31, 2020.

Contractual maturities of the Company’s debt obligations as of September 30, 2021 are as follows:

Year	Amount
2021 (remaining)	$	2.2
2022		9.0
2023		9.0
2024		9.0
2025		9.0
2026		788.5

11)	Product Warranties

The Company provides for the estimated costs to fulfill customer warranty obligations upon the recognition of the related revenue. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligations are affected by shipment volume, product failure rates, utilization levels, material usage and supplier warranties on parts delivered to the Company. Should actual product failure rates, utilization levels, material usage, or supplier warranties on parts differ from the Company’s estimates, revisions to the estimated warranty liability would be required.

Product warranty activities were as follows:

	Nine Months Ended September 30,
	2021			2020
Beginning of period	$	18.4		$	14.9
Provision for product warranties		30.4			20.2
Charges to warranty liability		(26.0	)		(19.0	)
End of period⁽¹⁾	$	22.8		$	16.1

⁽¹⁾

As of September 30, 2021, short-term product warranties of $21.7 and long-term product warranties of $1.1 were included within other current liabilities and other non-current liabilities, respectively, within the accompanying condensed consolidated balance sheet. As of September 30, 2020, short-term product warranties of $13.0 and long-term product warranties of $3.1 were included within other current liabilities and other non-current liabilities, respectively, within the accompanying condensed consolidated balance sheet.

12)	Income Taxes

The Company’s effective tax rates for the three and nine months ended September 30, 2021 were 20.4% and 17.6%, respectively. The effective tax rates for the three and nine months ended September 30, 2021 and related income tax expense, were lower than the U.S. statutory tax rate mainly due to the U.S. deduction for foreign derived intangible income, windfall benefits from stock compensation, and the geographic mix of income earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory tax rate, offset by the U.S. global intangible low-taxed income inclusion and additional withholding taxes on inter-company distributions due to the United Kingdom’s withdrawal from the European Union.

The Company’s effective tax rates for the three and nine months ended September 30, 2020 were 15.7% and 17.0%, respectively. The effective tax rates for the three and nine months ended September 30, 2020, and related income tax

expense, were lower than the U.S. statutory tax rate mainly due to the geographic mix of income earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory tax rate, benefits of stock compensation, and the U.S. deduction for foreign derived intangible income offset by the U.S. tax effects of the U.S. global intangible low-taxed income inclusion and the write-off of deferred tax assets related to certain foreign net operating losses.

As of September 30, 2021 and December 31, 2020, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was $47.3 and $47.0, respectively. The Company accrues interest expense, and if applicable, penalties, for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. As of September 30, 2021 and December 31, 2020, the Company had accrued interest on unrecognized tax benefits of approximately $0.9 and $0.7, respectively.

Over the next 12 months it is reasonably possible that the Company may recognize approximately $3.8 of previously net unrecognized tax benefits, excluding interest and penalties, related to various U.S. federal and foreign tax positions, primarily as a result of the expiration of certain statutes of limitations.

The Company and its subsidiaries are subject to examination by U.S. federal, state and foreign tax authorities. The U.S. federal statute of limitations remains open for tax years 2017 through the present. The statute of limitations for the Company’s tax filings in other jurisdictions varies between fiscal years 2015 through present. The Company has certain federal credit carryforwards and state tax loss and credit carryforwards that are open to examination for tax years 2000 through the present.

13)	Net Income Per Share

The following table sets forth the computation of basic and diluted net income per share:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Numerator:
Net income	$	132.4	$	91.7	$	401.2	$	234.5
Denominator:
Shares used in net income per common share – basic		55.5		55.2		55.4		55.1
Effect of dilutive securities:
Restricted stock units and stock appreciation rights		0.2		0.2		0.3		0.2
Shares used in net income per common share – diluted		55.7		55.4		55.7		55.3
Net income per common share:
Basic	$	2.39	$	1.66	$	7.24	$	4.26
Diluted	$	2.38	$	1.66	$	7.21	$	4.24

Basic earnings per share (“EPS”) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding (using the treasury stock method) if securities containing potentially dilutive common shares (restricted stock units (“RSUs”) and stock appreciation rights (“SARs”)) had been converted to such common shares, and if such assumed conversion is dilutive.

For the three and nine months ended September 30, 2021, there were 0.1 weighted-average restricted stock units that would have had an anti-dilutive effect on EPS and were excluded from the computation of diluted weighted-average shares. For the three and nine months ended September 30, 2020, there were no weighted-average restricted stock units that had an anti-dilutive effect on EPS and were excluded from the computation of diluted weighted-average shares.

14)	Stock-Based Compensation

The Company grants RSUs to employees and directors under the 2014 Stock Incentive Plan (the “2014 Plan”). The 2014 Plan is administered by the Compensation Committee of the Company’s Board of Directors. The 2014 Plan is intended to attract and retain employees and directors, and to provide an incentive for these individuals to assist the Company to achieve long-range performance goals and to enable these individuals to participate in the long-term growth of the Company.

The total stock-based compensation expense included in the Company’s condensed consolidated statements of operations and comprehensive income was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Cost of revenues	$	0.9	$	1.2	$	2.8	$	3.1
Research and development		1.1		1.0		3.3		3.0
Selling, general and administrative		6.9		5.1		21.7		15.9
Acquisition and integration costs		—		0.1		—		0.7
Total pre-tax stock-based compensation expense	$	8.9	$	7.4	$	27.8	$	22.7

At September 30, 2021, the total compensation expense related to unvested stock-based awards granted to employees and directors under the 2014 Plan that had not been recognized was $43.5. The Company determines the fair value of RSUs based on the closing market price of the Company’s common stock on the date of the award and estimates the fair value of SARs and employee stock purchase plan rights using the Black-Scholes valuation model. Such values are recognized as expense on a straight-line basis for time-based awards and using the accelerated graded vesting method for performance-based awards, both over the requisite service periods.

The following table presents the activity for RSUs under the 2014 Plan:

	Nine Months Ended September 30, 2021
	Outstanding RSUs			Weighted Average Grant Date Fair Value
RSUs – beginning of period		0.6		$	93.26
Granted		0.2		$	177.91
Vested		(0.3	)	$	95.47
RSUs – end of period		0.5		$	127.31

The Company had an immaterial amount of SARs outstanding as of September 30, 2021 and December 31, 2020.

15)	Stockholders’ Equity

Share Repurchase Program

On July 25, 2011, the Company’s Board of Directors approved a share repurchase program for the repurchase of up to an aggregate of $200 of its outstanding common stock from time to time in open market purchases, privately negotiated transactions or through other appropriate means. The timing and quantity of any shares repurchased depends upon a variety of factors, including business conditions, stock market conditions and business development activities, including, but not limited to, merger and acquisition opportunities. These repurchases may be commenced, suspended or discontinued at any time without prior notice. The Company has repurchased approximately 2.6 shares of common stock for approximately $127 pursuant to the program since its adoption. During the three and nine months ended September 30, 2021 and 2020, there were no repurchases of common stock.

Cash Dividends

Holders of the Company’s common stock are entitled to receive dividends when they are declared by the Company’s Board of Directors. In addition, the Company accrues dividend equivalents on the RSUs the Company assumed in the ESI Merger when dividends are declared by the Company’s Board of Directors. During the first quarter of 2021, the Company’s Board of Directors declared a cash dividend of $0.20 per share. During each of the second and third quarters of 2021, the Company’s Board of Directors declared a cash dividend of $0.22 per share. The total amount of the dividends declared in 2021 was

MKS INSTRUMENTS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions, except per share data)

$35.5, or $0.64 per share. During each of the first, second and third quarters of 2020, the Company’s Board of Directors declared a cash dividend of $0.20 per share, which totaled $33.0, or $0.60 per share.

On October 25, 2021, the Company’s Board of Directors declared a quarterly cash dividend of $0.22 per share to be paid on December 10, 2021 to stockholders of record as of November 29, 2021.

Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of the Company’s Board of Directors. In addition, under the Term Loan Facility and ABL Facility, the Company may be restricted from paying dividends under certain circumstances.

16)	Acquisition

Photon Control

On July 15, 2021, the Company completed its acquisition of Photon Control (the “Photon Control Acquisition”), pursuant to a definitive agreement (the “Arrangement Agreement”). Photon Control designs, manufactures and distributes a wide range of optical sensors and systems to measure temperature and position used in semiconductor wafer fabrication. At the effective time of the Photon Control Acquisition and pursuant to the terms and conditions of the Arrangement Agreement, each share of Photon Control’s common stock issued and outstanding as of immediately prior to the effective time of the Photon Control Acquisition, was converted into the right to receive CAD 3.60 per share in cash, without interest and subject to deduction for any required withholding tax. The Company paid to the former Photon Control securityholders aggregate consideration of CAD 378.6, or USD 302.7, excluding related transaction fees and expenses. The Company funded the payment of the aggregate consideration with available cash on hand. Photon Control is included in the Company’s Light & Motion segment.

The purchase price of Photon Control consisted of the following:

Cash paid for outstanding shares⁽¹⁾	$	302.7
Less: Cash and cash equivalents acquired		(34.3	)
Total purchase price, net of cash and cash equivalents acquired	$	268.4

⁽¹⁾

Represents cash paid of CAD 3.60 per share for approximately 105.2 shares of Photon Control common stock, without interest and subject to deduction for any required withholding tax.

Under the acquisition method of accounting, the total estimated acquisition consideration is allocated to the acquired tangible and intangible assets and assumed liabilities of Photon Control based on their fair values as of the acquisition date. Any excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed is allocated to goodwill. The Company expects that none of this goodwill or intangible assets will be deductible for tax purposes. The Company believes the amount of goodwill relative to identifiable intangible assets relates to enhancing the Company’s Surround the Chamber® portfolio by adding optical sensors for temperature control for critical etch and deposition applications in semiconductor wafer fabrication.

MKS INSTRUMENTS, INC.

(in millions, except per share data)

The following table summarizes the preliminary allocation of the purchase price to the fair values assigned to assets acquired and liabilities assumed at the date of the Photon Control Acquisition:

Current assets	$	51.4
Intangible assets		121.0
Goodwill		168.2
Other non-current assets		8.6
Total assets acquired		349.2
Current liabilities		13.7
Non-current deferred taxes		32.1
Other long-term liabilities		0.7
Total liabilities assumed		46.5
Fair value of assets acquired and liabilities assumed		302.7
Less: Cash and cash equivalents acquired		(34.3	)
Total purchase price, net of cash and cash equivalents acquired	$	268.4

The acquired intangible assets are being amortized on a straight-line basis, which approximates the economic use of the assets over their estimated useful lives.

The following table reflects the allocation of the acquired intangible assets and related estimate of useful lives:

Completed technology	$	110.0	9 years
Customer relationships	$	9.4	10 years
Trade names		0.2	0.5 years
Backlog		1.4	1.5 years
	$	121.0

While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. The net fair value of the acquired intangible assets was determined using the income approach. In performing these valuations, the key underlying judgments and assumptions used included the appropriate discount rates as well as forecasted revenue growth rates, gross profit and operating margins. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. The finalization of the purchase accounting assessment may result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company’s results of operations and financial position. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with a corresponding offset to goodwill to reflect additional information received about facts and circumstances which existed at the date of acquisition. The Company records adjustments to the assets acquired and liabilities assumed subsequent to the purchase price allocation period in the Company’s operating results in the period in which the adjustments are determined. Any potential adjustments made could be material in relation to the preliminary values presented.

The results of operations of the Photon Control business from the acquisition closing date of July 15, 2021 through September 30, 2021, were not material to the Company's results of operations. The acquisition was also not material to the Company’s results of operations, for the periods presented, on a pro forma basis.

19)	Commitments and Contingencies

In 2016, two putative class actions lawsuit captioned Dixon Chung v. Newport Corp., et al., Case No. A-16-733154-C, and Hubert C. Pincon v. Newport Corp., et al., Case No. A-16-734039-B, were filed in the District Court, Clark County, Nevada on behalf of a putative class of stockholders of Newport for claims related to the merger agreement (“Newport Merger Agreement”) between the Company, Newport, and a wholly-owned subsidiary of the Company (“Merger Sub”). The lawsuits named as defendants the Company, Newport, Merger Sub, and certain then current and former members of Newport’s board of directors. Both complaints alleged that Newport directors breached their fiduciary duties to Newport’s stockholders by agreeing to sell Newport through an inadequate and unfair process, which led to inadequate and unfair consideration, by agreeing to unfair deal protection devices and by omitting material information from the proxy statement. The complaints also alleged that the Company, Newport and Merger Sub aided and abetted the directors’ alleged breaches of their fiduciary duties. The District Court consolidated the actions, and plaintiffs later filed an amended complaint captioned In re Newport Corporation Shareholder Litigation, Case No. A-16-733154-B, in the District Court, Clark County, Nevada, on behalf of a putative class of Newport’s stockholders for claims related to the Newport Merger Agreement. The amended complaint alleged Newport’s former board of directors breached their fiduciary duties to Newport’s stockholders and that the Company, Newport and Merger Sub had aided and abetted these breaches and sought monetary damages, including pre- and post-judgment interest. In June 2017, the District Court granted defendants’ motion to dismiss and dismissed the amended complaint against all defendants but granted plaintiffs leave to amend.

On July 27, 2017, plaintiffs filed a second amended complaint containing substantially similar allegations but naming only Newport’s former directors as defendants. On August 8, 2017, the District Court dismissed the Company and Newport from the action. The second amended complaint seeks monetary damages, including pre- and post-judgment interest. The District Court granted a motion for class certification on September 27, 2018, appointing Mr. Pincon and Locals 302 and 612 of the International Union of Operating Engineers - Employers Construction Industry Retirement Trust as class representatives. On June 11, 2018, plaintiff Dixon Chung was voluntarily dismissed from the litigation. On August 9, 2019, plaintiffs filed a motion for leave to file a third amended complaint, which was denied on October 10, 2019. On August 23, 2019, defendants filed a motion for summary judgment. On January 23, 2020, the District Court entered its findings of fact, conclusions of law, and order granting defendants’ motion for summary judgment. On February 18, 2020, plaintiffs filed a notice of appeal from the District Court’s order granting defendants’ motion for summary judgment, as well as from the District Court’s prior orders granting defendants’ motion for a bench trial and denying plaintiffs’ motion for leave to file an amended complaint. On November 30, 2020, plaintiffs filed their opening brief in the Nevada Supreme Court in support of their appeal from the District Court’s orders. On January 29, 2021, defendants filed their answering brief, and on March 30, 2021, plaintiffs filed their reply brief. The Nevada Supreme Court has scheduled oral argument for December 15, 2021.

The Company is also subject to various legal proceedings and claims that have arisen in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters, and the matters noted above, will not have a material adverse effect on the Company’s results of operations, financial condition or cash flows.

20)	Subsequent Events and Pending Acquisition

On July 1, 2021, the Company entered into a definitive agreement (as amended from time to time, the “Implementation Agreement”) to acquire Atotech Limited (“Atotech”), a leading process chemicals technology company and a market leader in advanced electroplating solutions. Pursuant to the Implementation Agreement, the Company agreed to pay $16.20 per share in cash and 0.0552 of a share of MKS common stock for each outstanding common share of Atotech, for total cash and stock consideration of approximately $5,100. The acquisition is expected to close by the end of 2021, subject to the satisfaction of certain closing conditions, including receipt of required regulatory approvals, approval by the Royal Court of Jersey and approval by Atotech’s shareholders. The Company’s obligations to complete the acquisition are not subject to any financing condition. The Company intends to fund the cash portion of the transaction with a combination of available cash on hand and committed term loan debt financing. In connection with entering into the Implementation Agreement, the Company entered into (a) a commitment letter (the “Initial Commitment Letter”), dated as of July 1, 2021, with JPMorgan Chase Bank, N.A. and Barclays Bank PLC (collectively, the “Initial Commitment Parties”) and (b) joinders to the Initial Commitment Letter to add certain additional lender parties (the “Commitment Letter Joinders” and, together with the Initial Commitment Letter, the “Commitment Letter”) dated as of July 23, 2021, with the Initial Commitment Parties and the additional lenders party thereto (collectively, the “Supplemental Commitment Parties” and, together with the Initial Commitment Parties, the “Commitment Parties”), pursuant to which, subject to the terms and conditions set forth therein, the Commitment Parties committed to provide (i) a senior secured term loan credit facility in an aggregate principal amount of $5,300 (the “New Term Loan Facility”) and (ii) a senior secured revolving credit facility with aggregate total commitments of $500 (the “New Revolving Credit Facility”). The New Term Loan Facility and New Revolving Credit Facility would

Our primary served markets include semiconductor, industrial technologies, life and health sciences, and research and defense.

Recent Events

On July 15, 2021, we completed our previously announced acquisition of Photon Control (the “Photon Control Acquisition”), pursuant to a definitive agreement. Photon Control designs, manufactures and distributes a wide range of optical sensors and systems to measure temperature and position used in semiconductor wafer fabrication. At the effective time of the Photon Control Acquisition, each share of Photon Control’s common stock issued and outstanding as of immediately prior to the effective time of the Photon Control Acquisition was converted into the right to receive CAD 3.60 per share in cash, without interest and subject to deduction for any required withholding tax. We paid to the former Photon Control securityholders aggregate consideration of CAD 378.6 million or USD 302.7 million, excluding related transaction fees and expenses. We funded the payment of the aggregate consideration with available cash on hand. Photon Control is included in our Light & Motion (“L&M”) segment.

On July 1, 2021, we entered into a definitive agreement (as amended from time to time, the “Implementation Agreement”) to acquire Atotech, a leading process chemicals technology company and a market leader in advanced electroplating solutions. Pursuant to the Implementation Agreement, we agreed to pay $16.20 per share in cash and 0.0552 of a share of our common stock for each outstanding common share of Atotech, for total cash and stock consideration of approximately $5.1 billion. The acquisition is expected to close by the end of 2021, subject to the satisfaction of certain closing conditions, including receipt of required regulatory approvals, approval by the Royal Court of Jersey and approval by Atotech’s shareholders. Our obligations to complete the acquisition are not subject to any financing condition. We intend to fund the cash portion of the transaction with a combination of available cash on hand and committed term loan debt financing. In connection with entering into the Implementation Agreement, we entered into (a) a commitment letter (the “Initial Commitment Letter”), dated as of July 1, 2021, with JPMorgan Chase Bank, N.A. and Barclays Bank PLC (collectively, the “Initial Commitment Parties”) and (b) joinders to the Initial Commitment Letter to add certain additional lender parties (the “Commitment Letter Joinders” and, together with the Initial Commitment Letter, the “Commitment Letter”) dated as of July 23, 2021, with the Initial Commitment Parties and the additional lenders party thereto (collectively, the “Supplemental Commitment Parties” and, together with the Initial Commitment Parties, the “Commitment Parties”), pursuant to which, subject to the terms and conditions set forth therein, the Commitment Parties committed to provide (i) a senior secured term loan credit facility in an aggregate principal amount of $5.3 billion (the “New Term Loan Facility”) and (ii) a senior secured revolving credit facility with aggregate total commitments of $500 million (the “New Revolving Credit Facility”). The New Term Loan Facility and New Revolving Credit Facility would refinance the Term Loan Facility and ABL Facility, respectively, and the New Term Loan Facility would be used to finance a portion of the acquisition and to refinance certain existing indebtedness of Atotech.

On October 22, 2021, we completed the syndication of the New Term Loan Facility, comprised of two tranches: a USD 4.7 billion loan at LIBOR plus 2.25%, a floor of 0.50% and 0.25% of original issue discount, and a Euro tranche of EUR 0.5 billion (approximately USD 0.6 billion) at EURIBOR plus 2.75%, a floor of 0.00% and 0.25% of original issue discount. Proceeds from the anticipated New Term Loan Facility will be used to finance a portion of the acquisition of Atotech and to repay our existing Term Loan Facility and certain existing indebtedness of Atotech.

Segments and Markets

The Vacuum & Analysis (“V&A”) segment provides a broad range of instruments, components and subsystems which are derived from our core competencies in pressure measurement and control, flow measurement and control, gas and vapor delivery, gas composition analysis, electronic control technology, reactive gas generation and delivery, power generation and delivery, and vacuum technology.

The Light & Motion (“L&M”) segment provides a broad range of instruments, components and subsystems which are derived from our core competencies in lasers, photonics, optics, temperature sensing, precision motion control and vibration control.

The Equipment & Solutions (“E&S”) segment provides a range of products including laser-based systems for printed circuit board (“PCB”) manufacturing, which include flexible interconnect PCB processing systems and high-density interconnect solutions for rigid PCB manufacturing and substrate processing and multi-layer ceramic capacitor test systems.

Semiconductor Market

A significant portion of our sales is derived from products sold to semiconductor capital equipment manufacturers and semiconductor device manufacturers. Our products are used in major semiconductor processing steps, such as depositing thin films of material onto silicon wafer substrates, etching, cleaning, lithography, metrology and inspection.

Approximately 61% and 60% of our net revenues for the nine months ended September 30, 2021 and 2020, respectively, were from sales to semiconductor capital equipment manufacturers and semiconductor device manufacturers.

We anticipate that the semiconductor market will continue to account for a substantial portion of our sales. While the semiconductor device manufacturing market is global, major semiconductor capital equipment manufacturers are concentrated in China, Japan, South Korea, Taiwan and the United States.

Net revenues in our semiconductor market increased by $128.9 million, or 36%, for the three months ended September 30, 2021, compared to the same period in the prior year, primarily due to an increase of $113.2 million and $23.7 million from our V&A and L&M segments, respectively, offset by a decrease of $8.0 million from our E&S segment. Net revenues in our semiconductor market increased by $337.5 million, or 34%, for the nine months ended September 30, 2021, compared to the same period in the prior year, primarily due to an increase of $327.2 million and $33.8 million from our V&A and L&M segments, respectively, offset by a

decrease of $23.5 million from our E&S segment, resulting from the discontinuance of certain non-core products. The net revenues from our L&M segment for each of the three and nine months ended September 30, 2021 included $14.8 million from our acquisition of Photon Control.

The semiconductor capital equipment industry is subject to rapid demand shifts, which are difficult to predict, and we cannot be certain as to the timing or extent of future demand or any future weakness in the semiconductor capital equipment industry.

During the nine months ended September 30, 2021, we experienced supply chain disruptions and component shortages in our semiconductor market due to global capacity constraints compounded by increasing global demand as well as the ongoing COVID-19 pandemic. We expect these disruptions and shortages to continue in the near-term while our suppliers adjust to significant increases in demand and respond to the challenges posed by the COVID-19 pandemic, all of which may negatively impact revenue from our semiconductor market for the three months ending December 31, 2021.

Advanced Markets

In addition to the semiconductor market, our products are used in the industrial technologies, life and health sciences, and research and defense markets.

Industrial Technologies

Industrial technologies encompasses a wide range of diverse applications, such as flexible and rigid PCB processing/fabrication, glass coating, laser marking, measurement and scribing, natural gas and oil production, environmental monitoring and electronic thin films. Electronic thin films are a primary component of numerous electronic products including flat panel displays, light emitting diodes, solar cells and data storage media. Industrial technologies manufacturers are located in developed and developing countries across the globe.

Life and Health Sciences

Our products for life and health sciences are used in a diverse array of applications, including bioimaging, medical instrument sterilization, medical device manufacturing, analytical, diagnostic and surgical instrumentation, consumable medical supply manufacturing and pharmaceutical production.

Approximately 39% and 40% of our net revenues for the nine months ended September 30, 2021 and 2020, respectively, were from advanced markets.

Net revenues from customers in our advanced markets increased by $23.3 million, or 10%, for the three months ended September 30, 2021, compared to the same period in the prior year, primarily due to increases of $9.1 million, $8.6 million and $5.6 million from our L&M, V&A and E&S segments, respectively. The increases were primarily due to increases in net revenues from our industrial technologies market, mainly related to electronic component and solar markets. Net revenues from customers in our advanced markets increased by $178.4 million, or 26%, for the nine months ended September 30, 2021, compared to the same period in the prior year, primarily due to increases of $81.7 million, $54.2 million and $42.5 million from our E&S, V&A and L&M segments, respectively. The increases were primarily due to increases in net revenues from our industrial technologies market related to PCB manufacturing.

International Markets

A significant portion of our net revenues is from sales to customers in international markets. For the nine months ended September 30, 2021 and 2020, international revenues accounted for approximately 58% and 55%, respectively, of our total net revenues. A significant portion of our international net revenues was from China, Japan, South Korea and Taiwan. We expect international net revenues will continue to represent a significant percentage of our total net revenues for the foreseeable future.

Long-lived assets located outside of North America accounted for approximately 25% and 28% of our total long-lived assets as of September 30, 2021 and December 31, 2020, respectively. Long-lived assets include property, plant and equipment, net, right-of-use assets, and certain other assets and exclude goodwill, intangible assets and long-term tax-related accounts.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect the amounts reported. There have been no material changes in our critical accounting policies since December 31, 2020.

For further information about our critical accounting policies, please see the discussion of critical accounting policies in our Annual Report on Form 10-K for the year ended December 31, 2020 in the section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates.”

Research and development expenses increased $9.2 million for the three months ended September 30, 2021, compared to the same period in the prior year. The increase was primarily related to an increase of $6.2 million in compensation-related costs, an increase of $1.3 million in project material costs and an increase of $1.1 million in occupancy costs. Research and development expenses increased $21.2 million for the nine months ended September 30, 2021, compared to the same period in the prior year. The increase was primarily related to increases of $15.6 million in compensation-related costs, $3.7 million in project material costs and $2.2 million in occupancy costs. The acquisition of Photon Control accounted for $1.6 million of the increase in the three and nine months ended September 30, 2021, compared to the same periods in the prior year.

Our research and development efforts are primarily focused on developing and improving our instruments, components, subsystems and process control solutions to improve process performance and productivity.

We have thousands of products and our research and development efforts primarily consist of a large number of projects related to these products, none of which is individually material to us. Current projects typically have durations of 3 to 30 months, depending upon whether the product is an enhancement of existing technology or a new product. Our products have continuously advanced as we strive to meet our customers’ evolving needs. We have developed, and continue to develop, new products to address industry trends, such as the shrinking of integrated circuit critical dimensions and technology inflections, and, in the flat panel display and solar markets, the transition to larger substrate sizes, which require more advanced processing and process control technology, the continuing drive toward more complex and accurate components and devices within the handset and tablet market, the transition to 5G for both devices and infrastructure, supporting the growth in units and via counts of the high density interconnect PCB drilling market, and the industry transition to electric cars in the automotive market. In addition, we have developed, and continue to develop, products that support the migration to new classes of materials, ultra-thin layers, and 3D structures that are used in small geometry manufacturing. Research and development expenses consist primarily of salaries and related expenses for personnel engaged in

research and development, fees paid to consultants, material costs for prototypes and other expenses related to the design, development, testing and enhancement of our products.

We believe that the continued investment in research and development and ongoing development of new products are essential to the expansion of our markets. We expect to continue to make significant investment in research and development activities. We are subject to risks from products not being developed in a timely manner, as well as from rapidly changing customer requirements and competitive threats from other companies and technologies. Our success primarily depends on our products being designed into new generations of equipment for the semiconductor industry and advanced technology markets. We develop products that are technologically advanced so that they are positioned to be chosen for use in each successive generation of semiconductor capital equipment and advanced market applications. If our products are not chosen to be designed into our customers’ products, our net revenues may be reduced during the lifespan of those products.

Our effective tax rates for the three and nine months ended September 30, 2021 were 20.4% and 17.6%, respectively. Our effective tax rates for each of the three and nine months ended September 30, 2021 and related income tax expense were lower than the U.S. statutory tax rate mainly due to the U.S. deduction for foreign derived intangible income, windfall benefits from stock compensation, and the geographic mix of income earned by our international subsidiaries being taxed at rates lower than the U.S. statutory tax rate, offset by the U.S. global intangible low-taxed income inclusion and additional withholding taxes on inter-company distributions due to the United Kingdom’s withdrawal from the European Union

On March 11, 2021, President Biden signed into law the American Rescue Plan Act of 2021 (“ARPA”). The act contains numerous income tax provisions among other tax and non-tax provisions to provide COVID-19 pandemic relief. We have evaluated the ARPA legislation in relation to income taxes and we do not expect the ARPA income tax provisions to have a material impact on our financial statements in the current year. The ARPA income tax provisions that are effective in future years are being evaluated and we have not yet determined the impact on our consolidated financial statements.

On September 15, 2021, the House Ways and Means Committee approved tax proposals, including a series of corporate and international tax provisions one of which would increase the corporate tax rate from 21% to 26.5%. If this tax proposal is enacted in its current form, we expect our income tax expense would materially increase.

As of September 30, 2021 and December 31, 2020, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $47.3 million and $47.0 million, respectively. We accrue interest expense, and if applicable, penalties, for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. As of September 30, 2021 and December 31, 2020, we had accrued interest on unrecognized tax benefits of approximately $0.9 million and $0.7 million, respectively.

Over the next 12 months it is reasonably possible that we may recognize approximately $3.8 million of previously net unrecognized tax benefits, excluding interest and penalties, related to U.S. federal and state as well as foreign tax positions as a result of the expiration of statutes of limitation. The U.S. federal statute of limitations remains open for tax years 2017 through present. The statute of limitations for our tax filings in other jurisdictions varies between fiscal years 2015 through the present. We also have certain federal credit carryforwards and state tax loss and credit carryforwards that are open to examination for tax years 2000 through the present.

On a quarterly basis, we evaluate both positive and negative evidence that affects the realizability of net deferred tax assets and assess the need for a valuation allowance. The future benefit to be derived from our deferred tax assets is dependent upon our ability to generate sufficient future taxable income in each jurisdiction of the right type to realize the assets.

Our future effective tax rate depends on various factors, including the impact of tax legislation, further interpretations and guidance from U.S. federal and state governments on the impact of proposed regulations issued by the Internal Revenue Service, further interpretations and guidance from foreign governments, the geographic composition of our pre-tax income, and changes in income tax reserves for unrecognized tax benefits. We monitor these factors and timely adjust our estimates of the effective tax rate accordingly. We expect that the geographic mix of pre-tax income will continue to have a favorable impact on our effective tax rate. However, the geographic mix of pre-tax income can change based on multiple factors, resulting in changes to the effective tax rate in future periods. While we believe we have adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from our accrued positions as a result of uncertain and complex application of tax law and regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgment by management. Accordingly, we could record additional provisions or benefits for U.S. federal, state, and foreign tax matters in future periods as new information becomes available.

Liquidity and Capital Resources

On July 15, 2021, we completed our previously announced acquisition of Photon Control. We paid to the former Photon Control securityholders aggregate consideration of CAD 378.6 million or USD 302.7 million, excluding related transaction fees and expenses. We funded the payment of the aggregate consideration with available cash on hand.

Cash and cash equivalents and short-term marketable investments totaled $879.6 million at September 30, 2021, compared to $836.0 million at December 31, 2020. The primary driver in our current and anticipated future cash flows is and will continue to be cash generated from operations, consisting primarily of our net income, excluding non-cash charges and changes in operating assets and liabilities. In periods when our sales are growing, higher sales to customers will result in increased trade receivables, and inventories will generally increase as we build products for future sales. This may result in lower cash generated from operations. Conversely, in periods when our sales are declining, our trade accounts receivable and inventory balances will generally decrease, resulting in increased cash from operations.

Net cash provided by operating activities was $445.2 million for the nine months ended September 30, 2021 and resulted from net income of $401.2 million, which included non-cash charges of $126.6 million, offset by a net increase in working capital of $82.6 million. The net increase in working capital was primarily due to a decrease in income tax payable of $28.7 million, an increase in trade accounts receivable of $51.3 million and an increase in inventories of $61.7 million, partially offset by an increase in accounts payable of $38.2 million and an increase in other current and non-current liabilities of $18.6 million.

Net cash used in investing activities was $351.2 million for the nine months ended September 30, 2021, including the purchase of Photon Control for $268.4 million, net of cash acquired, the purchases of production-related equipment of $63.3 million and the net purchases of investments of $19.5 million.

Net cash used in financing activities was $61.7 million for the nine months ended September 30, 2021 and was primarily due to dividend payments of $35.5 million, net payments on short and long-term borrowings of $11.8 million and net payments related to tax payments on the vesting of employee stock awards of $14.4 million.

On July 25, 2011, our Board of Directors approved a share repurchase program for the repurchase of up to an aggregate of $200 million of our outstanding common stock from time to time in open market purchases, privately negotiated transactions or through other appropriate means. The timing and quantity of any shares repurchased depends upon a variety of factors, including business conditions, stock market conditions and business development activities, including but not limited to merger and acquisition opportunities. These repurchases may be commenced, suspended or discontinued at any time without prior notice. We have

repurchased approximately 2.6 million shares of common stock for approximately $127 million pursuant to the program since its adoption. During the three and nine months ended September 30, 2021 and 2020, there were no repurchases of common stock.

Holders of our common stock are entitled to receive dividends when and if they are declared by our Board of Directors. In addition, we accrue dividend equivalents on the restricted stock units we assumed in the ESI Merger when dividends are declared by our Board of Directors. During the first quarter of 2021, our Board of Directors declared a cash dividend of $0.20 per share. During each of the second and third quarters of 2021, our Board of Directors declared a cash dividend of $0.22 per share. The total amount of the dividends declared in 2021 was $35.5 million, or $0.64 per share. During each of the first, second, and third quarters of 2020, our Board of Directors declared a cash dividend of $0.20 per share, which totaled $33.0 million, or $0.60 per share.

On October 25, 2021, our Board of Directors declared a quarterly cash dividend of $0.22 per share to be paid on December 10, 2021 to stockholders of record as of November 29, 2021.

Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of our Board of Directors. In addition, under the terms of our Term Loan Facility and ABL Facility, each as defined and described further below, we may be restricted from paying dividends under certain circumstances.

Senior Secured Term Loan Credit Facility

In connection with the completion of the acquisition of Newport Corporation (“Newport”) in 2016 (the “Newport Merger”), we entered into a term loan credit agreement (as amended, the “Term Loan Credit Agreement”) with Barclays Bank PLC, as administrative agent and collateral agent, and the lenders from time to time party thereto, which provided a senior secured term loan credit facility (the “Term Loan Facility”) in the original principal amount of $780.0 million. We have entered into seven amendments to the Term Loan Credit Agreement since 2016, including most recently the May Term Loan Amendment (as defined below). The Term Loan Facility is subject to increase at our option and subject to receipt of lender commitments in accordance with the Term Loan Credit Agreement. The maturity date of the Term Loan Facility is February 2, 2026. As of September 30, 2021, borrowings under the Term Loan Facility bear interest per annum at one of the following rates selected by us: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, (3) a London Interbank Offered Rate (“LIBOR”) rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%, and (4) a floor of 1.00%, plus, in each case, an applicable margin of 0.75%; or (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, subject to a LIBOR rate floor of 0.0%, plus an applicable margin of 1.75%. We have elected the interest rate as described in clause (b) of the foregoing sentence. The Term Loan Credit Agreement provides that, unless an alternate rate of interest is agreed, all loans will be determined by reference to the base rate if the LIBOR rate cannot be ascertained, if regulators impose material restrictions on the authority of a lender to make LIBOR rate loans, or for other reasons.

In May 2021, we entered into an amendment (the “May Term Loan Amendment”) to the Term Loan Credit Agreement. The May Term Loan Amendment amends the Term Loan Facility to, among other things, (i) increase our ability to incur additional incremental debt facilities to (x) the greater of (1) $600.0 million and (2) 100% of consolidated EBITDA, plus (y) an amount equal to the sum of all voluntary prepayments of term loans under the Term Loan Facility, plus (z) an additional unlimited amount subject to pro forma compliance with a secured leverage ratio test of 3.25:1.00, and (ii) increase our flexibility under certain debt, lien, investment, restricted payment and disposition baskets. The fees incurred, including certain customary lender consent fees, in connection with the May Term Loan Amendment were immaterial.

As of September 30, 2021, we have incurred an aggregate amount of $42.6 million of deferred finance fees, original issue discount and repricing fees related to the term loans under the Term Loan Facility, which are included in long-term debt in the accompanying condensed consolidated balance sheets and are being amortized to interest expense over the estimated life of the term loans using the effective interest method. As of September 30, 2021, the remaining balance of deferred finance fees, original issue discount and repricing fees related to the term loans under the Term Loan Facility was $8.0 million. A portion of the deferred finance fees, original issue discount and repricing fees have been accelerated in connection with the various debt prepayments and amendments between 2016 and 2021.

We are required to make scheduled quarterly amortization payments each equal to 0.25% of the original principal amount of the Term Loan Facility.

As of September 30, 2021, after giving effect to all amendments and repayments prior to such date, the outstanding principal amount of the Term Loan Facility was $826.7 million, and the interest rate was 1.8%.

Under the Term Loan Credit Agreement, we are required to prepay outstanding term loans, subject to certain exceptions, with portions of our annual excess cash flow as well as with the net cash proceeds of certain of our asset sales, certain casualty and condemnation events and the incurrence or issuance of certain debt.

All obligations under the Term Loan Facility are guaranteed by certain of our domestic subsidiaries and are secured by substantially all of our assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

The Term Loan Credit Agreement contains customary representations and warranties, affirmative and negative covenants and provisions relating to events of default. If an event of default occurs, the lenders under the Term Loan Facility will be entitled to take various actions, including the acceleration of amounts due under the Term Loan Facility and all actions generally permitted to be taken by a secured creditor. At September 30, 2021, we were in compliance with all covenants under the Term Loan Credit Agreement.

Interest Rate Swap Agreements

We entered into various interest rate swap agreements as described further in Note 6 to the Condensed Consolidated Financial Statements that exchange the variable LIBOR interest rate to a fixed rate in order to manage the exposure to interest rate fluctuations associated with the variable LIBOR interest rate paid on the outstanding balance of the Term Loan Facility.

Senior Secured Asset-Based Revolving Credit Facility

In February 2019, in connection with the completion of the ESI Merger, we entered into an asset-based revolving credit agreement with Barclays Bank PLC, as administrative agent and collateral agent, the other borrowers from time to time party thereto, and the lenders and letters of credit issuers from time to time party thereto (the “ABL Credit Agreement”), that provides a senior secured asset-based revolving credit facility of up to $100.0 million, subject to a borrowing base limitation (the “ABL Facility”). We have entered into two amendments to the ABL Credit Agreement since 2019. As of September 30, 2021, after giving effect to all amendments, the borrowing base for the ABL Facility at any time equals the sum of: (a) 85% of certain eligible accounts; plus (b) prior to certain notice and field examination and appraisal requirements, the lesser of (i) 20% of net book value of eligible inventory in the United States and (ii) 30% of the borrowing base, and after the satisfaction of such requirements, the lesser of (i) the lesser of (A) 65% of the lower of cost or market value of certain eligible inventory and (B) 85% of the net orderly liquidation value of certain eligible inventory and (ii) 30% of the borrowing base; minus (c) reserves established by the administrative agent, in each case, subject to additional limitations and examination requirements for eligible accounts and eligible inventory acquired in an acquisition after February 1, 2019. The ABL Facility includes borrowing capacity in the form of letters of credit up to $25.0 million. We have not borrowed against the ABL Facility to date.

As of September 30, 2021, any borrowings under the ABL Facility bear interest at a rate per annum equal to, at our option, any of the following, plus, in each case, an applicable margin: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00% and (4) a floor of 0.00%, plus, in each case, an applicable margin ranging from 0.25% to 0.50%; and (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, with a floor of 0.00%, plus, in each case, an applicable margin ranging from 1.25% to 1.50%. The applicable margin for borrowings thereunder is subject to upward or downward adjustment each fiscal quarter, based on the average historical excess availability during the preceding quarter.

In addition to paying interest on any outstanding principal under the ABL Facility, we are required to pay a commitment fee in respect of the unutilized commitments thereunder equal to 0.25% per annum. We must also pay customary letter of credit fees and agency fees.

Under the ABL Facility, we are required to prepay amounts outstanding under the ABL Facility (1) if amounts outstanding under the ABL Facility exceed the lesser of (a) the commitment amount and (b) the borrowing base, in an amount required to reduce such shortfall, (2) if amounts outstanding under the ABL Facility in any currency other than U.S. dollars exceed the sublimit for such currency, in an amount required to reduce such shortfall, and (3) during any period in which we have excess availability less than the greater of (a) 10.0% of the lesser of (x) the commitment amount and (y) the borrowing base (the “Line Cap”) and (b) $8.5 million for 3 consecutive business days, until the time when we have excess availability equal to or greater than the greater of (A) 10.0% of the Line Cap and (B) $8.5 million for 30 consecutive days, or during the continuance of an event of default, with immediately available funds in our blocked accounts.

There is no scheduled amortization under the ABL Facility. Any principal amount outstanding under the ABL Facility is due and payable in full on the fifth anniversary of the closing date, subject to a springing maturity in the event that term loans under the Term Loan Facility in an aggregate amount of at least $100.0 million have an earlier maturity date than the ABL Facility.

All obligations under the ABL Facility are guaranteed by certain of our domestic subsidiaries and are secured by substantially all of our assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

From the time when we have excess availability less than the greater of (a) 10.0% of the Line Cap and (b) $8.5 million until the time when we have excess availability equal to or greater than the greater of (a) 10.0% of the Line Cap and (b) $8.5 million for 30 consecutive days, or during the continuance of an event of default, the ABL Credit Agreement requires that we maintain a fixed charge coverage ratio, tested on the last day of each fiscal quarter, of at least 1.0 to 1.0.

Lines of Credit and Borrowing Arrangements

Our Japanese subsidiaries have lines of credit and a financing facility with various financial institutions, many of which generally expire and are renewed at three-month intervals with the remaining having no expiration date. The lines of credit and financing facility provided for aggregate borrowings as of September 30, 2021 of up to an equivalent of $29.9 million U.S. dollars. There were no borrowings outstanding under these arrangements at September 30, 2021. Total borrowings outstanding under these arrangements were $5.5 million at December 31, 2020.

Atotech Acquisition

On July 1, 2021, we entered into an Implementation Agreement to acquire Atotech, a leading process chemicals technology company and a market leader in advanced electroplating solutions. Pursuant to the Implementation Agreement, we agreed to pay $16.20 per share in cash and 0.0552 of a share of our common stock for each outstanding common share of Atotech, for total cash and stock consideration of approximately $5.1 billion. The acquisition is expected to close by the end of 2021, subject to the satisfaction of certain closing conditions, including receipt of required regulatory approvals, approval by the Royal Court of Jersey and approval by Atotech’s shareholders. Our obligations to complete the acquisition are not subject to any financing condition. Additional information regarding the funding of the acquisition and the related syndication of the New Term Loan Facility is discussed under “Recent Events” above.

Off-Balance Sheet Arrangements

We do not have any financial partnerships with unconsolidated entities, such as entities often referred to as structured finance, special purpose or variable interest entities, which are often established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. Accordingly, we have no off-balance sheet arrangements that have or are reasonably expected to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

Contractual Obligations

There have been no other changes outside the ordinary course of business to our contractual obligations as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

Recently Issued Accounting Pronouncements

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU No. 2021-08"). ASU No. 2021-08 will require companies to apply the definition of a performance obligation under ASC Topic 606 to recognize and measure contract assets and contract liabilities (i.e., deferred revenue) relating to contracts with customers that are acquired in a business combination. Under current U.S. GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC Topic 606. ASU No. 2021-08 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. We are currently evaluating the impact of this ASU on our financial statements.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This standard provides temporary optional expedients and exceptions to accounting guidance on contract modifications and hedge accounting to ease entities’ financial reporting burdens, as the market transitions from the LIBOR and other interbank offered rates to alternative reference rates. The standard was effective upon issuance and generally can be applied through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” The amendments in this update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is

modified as a result of reference rate reform. Amendments in this update to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments in this update do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and existing hedging relationships evaluated for effectiveness in periods after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022). Our adoption of the requirements of these standards has not resulted in a material impact on our financial position, results of operations and cash flows, but the adoption of the requirements may impact us in the future.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Information concerning market risk is contained in the section entitled “Quantitative and Qualitative Disclosures About Market Risk” contained in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission on February 23, 2021. As of September 30, 2021, there were no material changes in our exposure to market risk from December 31, 2020.

ITEM 4.

CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2021, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
