PTC Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Basis of Presentation

General

The accompanying unaudited condensed consolidated financial statements include the accounts of PTC Inc. and its wholly owned subsidiaries and have been prepared by management in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and in accordance with the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. While we believe that the disclosures presented are adequate in order to make the information not misleading, these unaudited quarterly financial statements should be read in conjunction with our annual consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of those of a normal recurring nature, necessary for a fair statement of our financial position, results of operations and cash flows at the dates and for the periods indicated. The September 30, 2020 Consolidated Balance Sheet included herein is derived from our audited consolidated financial statements.

Unless otherwise indicated, all references to a year mean our fiscal year, which ends on September 30. In the first quarter of 2021, we changed our fiscal calendar from thirteen-week quarters ending on a Saturday to three-month quarters ending on the last calendar day of the third month. There was no change to our fiscal year-end. We do not expect that this change will materially impact comparability of our financial results for fiscal years 2021 and 2020. Because our fiscal year-end did not change, we were not required to file a transition report. The second quarter of 2021 ended on March 31, 2021 and the second quarter of 2020 ended on March 28, 2020. The results of operations for the six months ended March 31, 2021 are not necessarily indicative of the results expected for the remainder of the fiscal year.

Risks and Uncertainties - COVID-19 Pandemic

In December 2019, the virus that causes COVID-19 surfaced. The virus has spread worldwide, including in the United States, and has been declared a pandemic by the World Health Organization. The COVID-19 pandemic has significantly impacted global economic activity and has created macroeconomic uncertainty.

We assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to us and the unknown future impacts of the COVID-19 pandemic as of March 31, 2021 and through the date of this report. The accounting matters assessed included, but were not limited to, our allowance for doubtful accounts, stock-based compensation, the carrying value of our goodwill and other long-lived assets, financial assets, valuation allowances for tax assets and revenue recognition. While our assessment did not result in a material impact to our consolidated financial statements as of and for the quarter ended March 31, 2021, our future assessment could result in material impacts to our consolidated financial statements in future reporting periods.

Recently Adopted Accounting Pronouncements

Intangibles—Goodwill and Other—Internal-Use Software

In August 2018, the FASB issued Accounting Standards Update (ASU) 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which aligns the requirements for capitalizing implementation costs in cloud computing arrangements with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted the new standard prospectively effective October 1, 2020. As a result of the adoption, we are required to capitalize certain costs related to the implementation of cloud computing arrangements. Capitalized costs related to cloud computing arrangements, which are included in other assets on the Consolidated Balance Sheets, were not material as of March 31, 2020.

Financial Instruments—Credit Losses

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASC 326), which, along with subsequent amendments, replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information when recording credit loss estimates. We adopted the new standard effective October 1, 2020, with no impact on our consolidated financial statements.

Pending Accounting Pronouncements

Reference Rate Reform

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. The ASU provides optional guidance for contract modifications and certain hedging relationships associated with the transition from reference rates that are expected to be discontinued. ASU 2020-04 is effective for all entities upon issuance through December 31, 2022. We are still evaluating the impact, but do not expect the standard to have a material impact on our consolidated financial statements.

Income Taxes

In December 2019, the FASB issued Accounting Standards Update ASU 2019-12, Income Taxes (Topic 740) on Simplifying the Accounting for Income Taxes. The decisions reflected in ASU 2019-12 update specific areas of ASC 740, Income Taxes, to reduce complexity while maintaining or improving the usefulness of the information provided to users of financial statements. The new standard will be effective for us in the first quarter of 2022, though early adoption of the amendments is permitted. We are currently evaluating the impact the standard will have on our consolidated financial statements, but at this time we do not expect it to be material.

2. Revenue from Contracts with Customers

Contract Assets and Contract Liabilities

(in thousands) |  | March 31, 2021 |  |  | September 30, 2020 |
Contract asset |  | $ | 10,328 |  |  | $ | 11,984 |
Deferred revenue |  | $ | 492,421 |  |  | $ | 426,465 |

As of March 31, 2021, $7.6 million of our contract assets are expected to be transferred to receivables within the next 12 months and therefore are included in other current assets. The remainder is included in other long-term assets and expected to be transferred within the next 24 months. Approximately $6.3 million of the September 30, 2020 contract asset balance was transferred to receivables during the six months ended March 31, 2021 as a result of the right to payment becoming unconditional. Additions to contract assets of approximately $4.6 million related to revenue recognized in the period, net of billings. The majority of the contract asset balance relates to two large professional services contracts with invoicing terms based on performance milestones. There were no impairments of contract assets during the six months ended March 31, 2021.

Table of Contents

During the six months ended March 31, 2021, we recognized $302.9 million of revenue that was included in deferred revenue as of September 30, 2020 and there were additional deferrals of $353.3 million, primarily related to new billings. In addition, deferred revenue increased by $15.5 million as a result of the acquisition of Arena. For subscription contracts, we generally invoice customers annually. The balance of total short- and long-term receivables as of September 30, 2020 was $511.3 million, compared to total short- and long-term receivables as of March 31, 2021 of $578.1 million.

Our multi-year, non-cancellable on-premise subscription contracts provide customers with an annual right to exchange software within the subscription with other software. As of March 31, 2021 and September 30, 2020, the total refund liability was $39.6 million and $34.5 million, respectively, primarily associated with the annual right to exchange on-premise subscription software.

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Effective October 1, 2020, we adopted ASC 326, Financial Instruments—Credit Losses, which replaces the incurred loss impairment model with an expected loss model that requires the use of forward-looking information to calculate credit loss estimates. In determining the adequacy of the allowance for doubtful accounts, management specifically analyzes individual accounts receivable, historical bad debts, customer concentrations, customer credit-worthiness, current economic conditions, and accounts receivable aging trends. Our allowance for doubtful accounts on trade accounts receivable was $0.5 million as of March 31, 2021 and September 30, 2020. Uncollectible trade accounts receivable written-off and bad debt expense were immaterial in the three and six months ended March 31, 2021.

Costs to Obtain a Contract

We recognize an asset for the incremental costs of obtaining a contract with a customer if the benefit of those costs is expected to be longer than one year. These deferred costs primarily relate to commissions. As of March 31, 2021 and September 30, 2020, deferred costs to obtain a contract of $41.0 million and $33.9 million, respectively, are included in other current assets and $73.4 million and $72.9 million, respectively, are included in other assets (non-current). Amortization expense related to costs to obtain a contract with a customer was $11.0 million and $21.4 million in the three and six months ended March 31, 2021, respectively, and $8.5 million and $16.2 million in the three and six months ended March 28, 2020, respectively. There were no impairments of the contract cost asset in the three and six months ended March 31, 2021 and March 28, 2020.

Remaining Performance Obligations

Our contracts with customers include amounts allocated to performance obligations that will be satisfied at a later date. As of March 31, 2021, the amounts include performance obligations of $492.4 million recorded in deferred revenue and $894.5 million that are not yet recorded in the Consolidated Balance Sheets. We expect to recognize approximately 85% of the total $1,386.9 million over the next 24 months, with the remaining amount thereafter. Certain of our multi-year subscription contracts with start dates on or after October 1, 2018 contain a limited annual cancellation right. For such cancellable subscription contracts, we consider each annual period a discrete contract. Early in the fourth quarter of 2019, we discontinued offering this cancellation right for substantially all new contracts. Remaining performance obligations do not include the cancellable value for subscriptions which contain this cancellation right.

Restructuring Charges

During the first quarter of 2020, we initiated a restructuring program as part of a realignment associated with expected synergies and operational efficiencies related to the Onshape acquisition. The restructuring plan resulted in charges of $30.8 million through fiscal year 2020 for termination benefits associated with approximately 250 employees. During the six months ended March 31, 2021, we incurred charges of $0.2 million in connection with this restructuring plan.

4. Stock-based Compensation

Our equity incentive plan provides for grants of nonqualified and incentive stock options, common stock, restricted stock, restricted stock units (RSUs) and stock appreciation rights to employees, directors, officers and consultants. We award RSUs, including performance-based awards, as our principal equity incentive awards.

The following table shows RSU activity for the six months ended March 31, 2021:

(in thousands, except grant date fair value data) |  | Number of RSUs |  |  | Weighted-Average Grant Date Fair Value Per RSU |
Balance of outstanding restricted stock units, October 1, 2020 |  |  | 3,509 |  |  | $ | 79.13 |
Granted(1) |  |  | 1,004 |  |  | $ | 103.64 |
Vested |  |  | (861 | ) |  | $ | 79.86 |
Forfeited or not earned |  |  | (67 | ) |  | $ | 80.39 |
Balance of outstanding restricted stock units, March 31, 2021 |  |  | 3,585 |  |  | $ | 85.91 |

(1) | Restricted stock granted includes 33,000 shares from prior period TSR awards that were earned upon achievement of the performance criteria and vested in November 2020.

The following table presents the number of RSU awards granted by award type:

(in thousands) |  | Six months ended March 31, 2021 |
Performance-based RSUs(1) |  |  | 90 |
Service-based RSUs(2) |  |  | 791 |
Total Shareholder Return RSUs(3) |  |  | 90 |

(1) | The performance-based RSUs were granted to our executives and are eligible to vest based upon annual performance measures over a three-year period. To the extent earned, those performance-based RSUs will vest in three substantially equal installments on November 15, 2021, 2022 and 2023, or the date the Compensation Committee determines the extent to which the applicable performance criteria have been achieved for each performance period. Up to a maximum of two times the number of RSUs can be earned (a maximum aggregate of 179,000 RSUs).

(2) | The service-based RSUs were granted to employees, including our executive officers. Substantially all service-based RSUs will vest in three substantially equal annual installments on or about the anniversary of the date of grant.

(3) | The Total Shareholder Return RSUs (TSR RSUs) were granted to our executives and are eligible to vest based on the performance of PTC stock relative to the stock performance of an index of PTC peer companies established as of the grant date, as determined at the end of three measurement periods ending on September 30, 2021, 2022 and 2023, respectively. The RSUs earned for each period will vest on November 15, 2021, 2022, and 2023. Up to a maximum of two times the number of TSR RSUs eligible to be earned for the period (up to a maximum aggregate of 179,000 RSUs) may vest. If the return to PTC shareholders is negative for a period but still meets or exceeds the peer group indexed return, a maximum of 100% of the eligible TSR RSUs may vest for the measurement period.

The weighted-average fair value of the TSR RSUs was $124.04 per target RSU on the grant date. The fair value of the TSR RSUs was determined using a Monte Carlo simulation model.

The significant assumptions used in the Monte Carlo simulation model were as follows:

Average volatility of peer group |  |  | 41.5 | %
Risk free interest rate |  |  | 0.21 | %
Dividend yield |  |  | — | %

Common Stock Repurchases

Our Articles of Organization authorize us to issue up to 500 million shares of our common stock. Our Board of Directors has authorized us to repurchase up to $1 billion of our common stock in the period October 1, 2020 through September 30, 2023. We did not repurchase any shares in the second quarter and first six months of 2021 or 2020. All shares of our common stock repurchased are automatically restored to the status of authorized and unissued.

6. Acquisitions

Acquisition-related costs in the second quarter and first six months of 2021 totaled $10.3 million and $14.2 million, respectively, compared to $0.3 million and $7.4 million, respectively, in the second quarter and first six months of 2020. These costs are classified in general and administrative expenses in the accompanying Consolidated Statements of Operations.

Our results of operations include the results of acquired businesses beginning on their respective acquisition date. Our results of operations for the reported periods if presented on a pro forma basis would not differ materially from our reported results.

Arena

On January 15, 2021, we acquired Arena Holdings, Inc. (“Arena”) pursuant to the Agreement and Plan of Merger dated as of December 12, 2020 by and among PTC, Arena, Astronauts Merger Sub, Inc.,

12

Table of Contents

and the Representative named therein, the material terms of which are described in the Form 8-K filed by PTC on December 14, 20 20 and which is filed as Exhibit 1.1 to that Form 8-K. PTC paid approximately $715 million, net of cash acquired of $11.3 million, for Arena, which amount was financed with cash on hand and $600 million borrowed under our existing credit facility. Arena had approximately 170 employees on the close date. The acquisition of Arena is expected to add revenue of approximately $40 million in 202 1.

The acquisition of Arena has been accounted for as a business combination. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the acquisition date. The fair values of intangible assets were based on valuations using a discounted cash flow model which requires the use of significant estimates and assumptions, including estimating future revenues and costs. The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill.

The purchase price allocation resulted in $562.7 million of goodwill, $155.0 million of customer relationships, $38.3 million of purchased software, $4.2 million of trademarks, $41.3 million of deferred tax liabilities, $15.5 million of deferred revenue, $11.4 million of accounts receivable, and $0.4 million of other net liabilities. The acquired customer relationships, purchased software, and trademarks are being amortized over useful lives of 13 years, 9 years, and 12 years, respectively, based on the expected economic benefit pattern of the assets. The acquired goodwill was allocated to our software products segment and will not be deductible for income tax purposes. The resulting amount of goodwill reflects the expected value that will be created by participation in expected future growth of the PLM SaaS market and expansion into the mid-market for PLM, where SaaS solutions are becoming the standard.

Onshape

On November 1, 2019, we acquired Onshape Inc. pursuant to the Agreement and Plan of Merger dated as of October 23, 2019 by and among Onshape Inc., OPAL Acquisition Corporation and the Stockholder Representative named therein, the material terms of which are described in the Form 8-K filed by PTC on October 23, 2019 and which is filed as Exhibit 1.1 to that Form 8-K. PTC paid approximately $469 million, net of cash acquired of $7.5 million, for Onshape, which amount we borrowed under our existing credit facility. Onshape had approximately 110 employees on the close date. The acquisition of Onshape did not add material revenue in 2020.

The acquisition of Onshape has been accounted for as a business combination. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the acquisition date. The fair values of intangible assets were based on valuations using a discounted cash flow model which requires the use of significant estimates and assumptions, including estimating future revenues and costs. The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill.

The purchase price allocation resulted in $364.9 million of goodwill, $56.8 million of customer relationships, $47.3 million of purchased software, $3.6 million of trademarks and $4.1 million of other net liabilities. The acquired customer relationships, purchased software, and trademarks are being amortized over useful lives of 10 years, 16 years, and 15 years, respectively, based on the expected economic benefit pattern of the assets. The acquired goodwill was allocated to our software products segment and will not be deductible for income tax purposes. The resulting amount of goodwill reflects the expected value that will be created by the expected acceleration of CAD and PLM growth, especially in the low end of the market, and participation in expected future growth of the CAD and PLM SaaS market. In addition, over the longer term, we anticipate building products based on the Onshape SaaS technology platform, which is the basis for Atlas.

7. Goodwill and Intangible Assets

We have two operating and reportable segments: (1) Software Products and (2) Professional Services.

As of March 31, 2021, goodwill and acquired intangible assets in the aggregate attributable to our Software Products segment was $2,558.7 million and attributable to our Professional Services segment was $45.2 million. As of September 30, 2020, goodwill and acquired intangible assets in the aggregate

13

Table of Contents

attributable to our Software Products segment was $1,818.1 million and attributable to our Professional Services segment was $45.3 million.

We completed our annual goodwill impairment review as of June 27, 2020 based on a quantitative assessment. To conduct these tests of goodwill, the fair value of a reporting unit is compared to its carrying value. If the reporting unit’s carrying value exceeds its fair value, we record an impairment loss equal to the difference between the carrying value of goodwill and its estimated fair value. We estimate the fair values of our reporting units using discounted cash flow valuation models. Those models require estimates of future revenues, profits, capital expenditures, working capital, terminal values based on revenue multiples, and discount rates for each reporting unit. We estimate these amounts by evaluating historical trends; current budgets and operating plans, including consideration of the impact of the COVID-19 pandemic on our future results; and industry data. The estimated fair value of each reporting unit exceeded its carrying value as of June 27, 2020. Through March 31, 2021, there were no events or changes in circumstances that indicated that the carrying values of goodwill or acquired intangible assets may not be recoverable.

Goodwill and acquired intangible assets consisted of the following:

8. Fair Value Measurements

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. There are three levels of inputs that are used to measure fair value:

14

Table of Contents

| • | Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

| • | Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities 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; or

| • | 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.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Time deposits and corporate notes/bonds are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets.

Foreign currency derivative contracts are typically classified within Level 2 of the fair value hierarchy. The principal market in which we execute our foreign currency derivatives is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants are usually large financial institutions. Our foreign currency derivatives’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment.

Our significant financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2021 and September 30, 2020 were as follows:

10. Derivative Financial Instruments

We enter into derivative transactions, specifically foreign currency forward contracts and options, to manage our exposure to foreign currency exchange risk in order to reduce earnings volatility. We do not enter into derivatives transactions for trading or speculative purposes.

The following table shows our derivative instruments measured at gross fair value as reflected in the Consolidated Balance Sheets:

Non-Designated Hedges

We hedge our net foreign currency monetary assets and liabilities primarily resulting from foreign currency denominated receivables and payables with foreign exchange forward contracts to reduce

Table of Contents

the risk that our earnings and cash flows will be adversely affected by changes in foreign currency exchange rates. These contracts have maturities of up to approximately three months. Generally, we do not designate these foreign currency forward contracts as hedges for accounting purposes and changes in the fair value of these instruments are recognized immediately in earnings. Because we enter into forward contracts only as an economic hedge, any gain or loss on the underlying foreign-denominated balance would be offset by the loss or gain on the forward contract. Gains and losses on forward contracts and foreign denominated receivables and payables are included in other expense, net.

We hedge our forecasted U.S. Dollar cash flows with foreign exchange options to reduce the risk that they would be adversely affected by changes in Euro exchange rates. These contracts have maturities of up to approximately ten months. We do not designate these foreign currency options as hedges for accounting purposes and changes in the fair value of these instruments are recognized immediately in earnings. Because we enter into options only as an economic hedge, any loss on the underlying Euro-denominated forecasted plan rate would be offset by the gain on the put option. Gains on put options are included in other expense, net.

As of March 31, 2021 and September 30, 2020, we had outstanding forward contracts and options with notional amounts equivalent to the following:

Currency Hedged (in thousands) |  | March 31, 2021 |  |  | September 30, 2020 |
Canadian / U.S. Dollar |  | $ | 5,824 |  |  | $ | 6,847 |

Net Investment Hedges

We translate balance sheet accounts of subsidiaries with foreign functional currencies into the U.S. Dollar using the exchange rate at each balance sheet date. Resulting translation adjustments are reported as a component of accumulated other comprehensive loss on the Consolidated Balance Sheets. We designate certain foreign exchange forward contracts as net investment hedges against exposure on translation of balance sheet accounts of Euro functional subsidiaries. Net investment hedges partially offset the impact of foreign currency translation adjustment recorded in accumulated other comprehensive loss on the Consolidated Balance Sheets. All foreign exchange forward contracts are carried at fair value on the Consolidated Balance Sheets and the maximum duration of net investment hedge foreign exchange forward contracts is approximately three months.

17

Table of Contents

Net investment hedge relationships are designated at inception, and effectiveness is assessed retrospectively on a quarterly basis using the net equity position of Euro functional subsidiaries. As the forward contracts are highly effective in offsetting exchange rate exposure, we record changes in these net investment hedges in accumulated other comprehensive loss and subsequently reclassify them to foreign currency translation adjustment in accumulated other comprehensive loss at the time of forward contract maturity. Changes in the fair value of foreign exchange forward contracts due to changes in time value are excluded from the assessment of effectiveness. Our derivatives are not subject to any credit contingent features. We manage credit risk with counterparties by trading among several counterparties and we review our counterparties’ credit at least quarterly.

As of March 31, 2021 and September 30, 2020, we had outstanding forward contracts designated as net investment hedges with notional amounts equivalent to the following:

Currency Hedged (in thousands) |  | March 31, 2021 |  |  | September 30, 2020 |

As of March 31, 2021, we estimate that all amounts reported in accumulated other comprehensive loss will be applied against exposed balance sheet accounts upon translation within the next three months.

Offsetting Derivative Assets and Liabilities

We have entered into master netting arrangements for our forward contracts that allow net settlements under certain conditions. Although netting is permitted, it is currently our policy and practice to record all derivative assets and liabilities on a gross basis in the Consolidated Balance Sheets.

The following table sets forth the offsetting of derivative assets as of March 31, 2021:

11. Segment and Geographic Information

We operate within a single industry segment – computer software and related services. We have two operating and reportable segments: (1) Software Products, which includes license, subscription, SaaS, and related support revenue (including updates and technical support) for all our products; and (2) Professional Services, which includes consulting, implementation and training services. We do not allocate sales and marketing or general and administrative expense to our operating segments as these activities are managed on a consolidated basis. Additionally, segment profit does not include stock-based compensation, amortization of intangible assets, restructuring charges and certain other identified costs that we do not allocate to the segments for purposes of evaluating their operational performance.

The revenue and profit attributable to our operating segments are summarized below. We do not produce asset information by reportable segment; therefore, it is not reported.

12. Income Taxes

In the second quarter and first six months of 2021 and 2020, our effective tax rate differed from the statutory federal income tax rate of 21% due to U.S. tax reform, our corporate structure in which our foreign taxes are at a net effective tax rate lower than the U.S. rate, and the excess tax benefit related to stock-based compensation. A significant amount of our foreign earnings is generated by our subsidiaries organized in Ireland. In 2021 and 2020, the foreign rate differential predominantly relates to these Irish earnings. In addition, the effective tax rate was impacted by the matters described below.

Our results for the six months ended March 31, 2021 include a charge of $36.1 million related to the effects of a tax matter in the Republic of Korea (South Korea) of $33.2 million, and the resulting impact on U.S. income taxes of $2.9 million. The charge relates to an assessment with respect to various tax issues, primarily foreign withholding taxes, under appeal in South Korea. We received an assessment of approximately $12 million from the tax authorities in South Korea in the fourth quarter of 2016 for the years 2011 to 2015 and paid the assessment in the first quarter of 2017. We appealed that assessment and believed that upon completion of the multi-level appeal process it was more likely than not that our positions would be sustained. However, in December 2020, our appeal to the Seoul High Court (an intermediate appellate court) was rejected. We have appealed this decision to the Supreme Court of the Republic of Korea. We continue to believe that our position is meritorious, and we will aggressively pursue our position with the Supreme Court.

In the second quarter of 2021, we reduced our previously established U.S. valuation allowance by $42.3 million as a result of the Arena acquisition. In the first six months of 2020, we reduced our previously established U.S. valuation allowance by $21.2 million as a result of the Onshape acquisition.

We have concluded, based on the weight of available evidence, that a full valuation allowance continues to be required against our U.S. net deferred tax assets as they are not more likely than not to be realized in the future. However, we believe that there is a reasonable possibility that within the next 12 months, sufficient positive evidence may become available to allow us to reach a conclusion that a significant portion of the valuation allowance will no longer be needed. Release of the valuation allowance would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period the release is recorded. However, the exact timing and amount of any valuation allowance release are subject to change on the basis of the level of profitability that we are able to actually achieve. We will continue to reassess our valuation allowance requirements each financial reporting period.

In the normal course of business, PTC and its subsidiaries are examined by various taxing authorities, including the Internal Revenue Service in the U.S. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. We are currently under audit by tax authorities in several jurisdictions. Audits by tax authorities typically involve examination of the deductibility of certain permanent items, limitations on net operating losses and tax credits.

As of March 31, 2021 and September 30, 2020, we had unrecognized tax benefits of $47.7 million and $16.1 million, respectively. If all our unrecognized tax benefits as of March 31, 2021 were to become recognizable in the future, we would record a benefit to the income tax provision of $47.7 million, which would be partially offset by an increase in the U.S. valuation allowance of $9.7 million.

Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in favorable or unfavorable changes in our estimates. We believe it is reasonably possible that within the next 12 months the amount of unrecognized tax benefits related to the resolution of multi-jurisdictional tax positions could be reduced by up to $28 million.

(1) | Unamortized debt issuance costs related to the credit facility were $4.4 million and $4.9 million as of March 31, 2021 and September 30, 2020, respectively, and are included in other assets on the Consolidated Balance Sheets.

(2) | Unamortized debt issuance costs are included in long-term debt on the Consolidated Balance Sheets.

Senior Notes

In February 2020, we issued $500 million in aggregate principal amount of 4.0% senior, unsecured long-term debt at par value, due in 2028 (the 2028 notes) and $500 million in aggregate principal amount of 3.625% senior, unsecured long-term debt at par value, due in 2025 (the 2025 notes).

As of March 31, 2021, the total estimated fair value of the 2028 and 2025 notes was approximately $508.6 million and $513.4 million, respectively, based on quoted prices for the notes on that date.

We were in compliance with all the covenants for all of our senior notes as of March 31, 2021.

Credit Agreement

In February 2020, we entered into a secured multi-currency bank credit facility with a syndicate of banks. We expect to use the new credit facility for general corporate purposes, including acquisitions of businesses, share repurchases and working capital requirements.

The credit facility consists of a $1 billion revolving credit facility, which may be increased by up to an additional $500 million in the aggregate if the existing or additional lenders are willing to make such increased commitments. The maturity date of the credit facility is February 13, 2025, when all remaining amounts outstanding will be due and payable. The revolving loan commitment does not require amortization of principal and may be repaid in whole or in part prior to the scheduled maturity date at our option without penalty or premium. As of March 31, 2021, the fair value of our credit facility approximates its book value.

Loans under the credit facility bear interest at variable rates which reset every 30 to 180 days depending on the rate and period selected by PTC as described below. As of March 31, 2021, the annual rate for borrowings outstanding was 1.75%. Interest rates on borrowings outstanding under the credit facility range from 1.25% to 1.75% above an adjusted LIBO rate (or an agreed successor rate) for Euro currency borrowings or range from 0.25% to 0.75% above the defined base rate (the greater of the Prime Rate, the NYFRB rate plus 0.5%, or an adjusted LIBO rate plus 1%) for base rate borrowings, in each case based upon PTC’s total leverage ratio. Additionally, PTC may borrow certain foreign currencies at rates set in the same range above the respective LIBO rates (or agreed successor rates) for those currencies, based on PTC’s total leverage ratio. A quarterly commitment fee on the undrawn portion of the credit facility is required, ranging from 0.175% to 0.30% per annum based upon PTC’s total leverage ratio.

As of March 31, 2021, we were in compliance with all financial and operating covenants of the credit facility.

We made interest payments on our debt of $19.8 million and $20.5 million in the second quarter and first six months of 2021, respectively, and $6.8 million and $23.7 million in the second quarter and first six months of 2020, respectively. The average interest rate on borrowings outstanding was approximately 3.3% and 3.5% during the second quarter and first six months of 2021, respectively, and 4.6% and 4.8% during the second quarter and first six months of 2020, respectively.

14. Leases

Our operating leases expire at various dates through 2037 and are primarily for office space, cars, servers, and office equipment.

Our headquarters are located at 121 Seaport Boulevard, Boston, Massachusetts. In February 2019, we subleased a portion of our headquarters through June 30, 2022. We will receive approximately $9.1 million in sublease income over the term of the sublease.

The components of lease cost reflected in the Consolidated Statement of Operations for the three and six months ended March 31, 2021 and March 28, 2020 were as follows:

Exited (Restructured) Facilities

As of March 31, 2021, we had net liabilities of $5.3 million related to excess facilities (compared to $11.3 million at September 30, 2020), representing $1.9 million of right-of-use assets and $7.2 million of lease obligations, of which $4.7 million is classified as short term and $2.5 million is classified as long term. Variable costs related to these exited facilities are included in our restructuring accrual. All expenses and income associated with exited facilities are included in restructuring and other charges, net (refer to Note 3. Restructuring and Other Charges).

In determining the amount of right-of-use assets for restructured facilities, we are required to estimate such factors as future vacancy rates, the time required to sublet properties and sublease rates. Updates to these estimates may result in revisions to the value of right-of-use assets recorded. The amounts recorded are based on the net present value of estimated sublease income. As of March 31, 2021, the right-of-use assets for exited facilities reflects discounted committed sublease income of approximately $1.9 million.

In the three and six months ended March 31, 2021, we made payments of $2.5 million and $6.3 million, respectively, related to lease costs for exited facilities. In the three and six months ended March 28, 2020, we made payments of $2.1 million and $4.5 million, respectively.

15. Commitments and Contingencies

Legal and Regulatory Matters

South Korean Tax Audit

We continue to appeal an assessment from the tax authorities in South Korea. In the first quarter of 2021, we recorded a charge of $36.1 million associated with this matter. See Note 12. Income Taxes for additional information.

Legal Proceedings

With respect to legal proceedings and claims, we record an accrual for a contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

401(k) Plan

On September 17, 2020, three individual plaintiffs filed a putative class action lawsuit against PTC, the Investment Committee for the PTC Inc. 401(k) Plan (“Plan”), and the Board of Directors (the “PTC Defendants”) in the U.S. District Court for the District of Massachusetts alleging claims regarding the Plan. Plaintiffs allege that the defendants breached their fiduciary duties under the Employee Retirement Income Security Act of 1974 ("ERISA") in the oversight of the Plan, principally by allegedly selecting and retaining certain investment options despite their higher fees and costs than other available investment options, causing participants in the Plan to pay excessive recordkeeping fees and suffer lower returns on their investments, and by allegedly failing to monitor other fiduciaries. The plaintiffs seek unspecified damages on behalf of a class of Plan participants from September 17, 2014 through the date of any judgment. An answer to the complaint was filed on May 4, 2021. We are currently unable to reasonably estimate what effect the ultimate outcome might have, if any, on our financial position, results of operations or cash flows.

Other Legal Proceedings

In addition to the matters listed above, we are subject to legal proceedings and claims against us in the ordinary course of business. As of March 31, 2021, we estimate that the range of possible outcomes for such matters is immaterial and we do not believe that resolving them will have a material adverse impact on our financial condition, results of operations or cash flows. However, the results of legal proceedings cannot be predicted with certainty. Should any of these legal proceedings and claims be resolved against us, the operating results for a reporting period could be adversely affected.

Guarantees and Indemnification Obligations

We enter into standard indemnification agreements with our customers and business partners in the ordinary course of our business. Under such agreements, we typically indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to our products. Indemnification may also cover other types of claims, including claims relating to certain data breaches. Except for intellectual property infringement indemnification, the liability for which is uncapped, these agreements typically limit our liability with respect to other indemnification claims. Historically, our costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and, accordingly, we believe the estimated fair value of liabilities under these agreements is immaterial.

We warrant that our software products will perform in all material respects in accordance with our standard published specifications during the term of the license/subscription. Additionally, we generally warrant that our consulting services will be performed consistent with generally accepted industry standards and, in the case of fixed price services, the agreed-upon specifications. In most cases, liability for these warranties is capped. If necessary, we would provide for the estimated cost of product and service warranties based on specific warranty claims and claim history; however, we have not incurred significant cost under our product or services warranties. As a result, we believe the estimated fair value of these liabilities is immaterial.

ITEM 2. | MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Business Overview

PTC is a global software and services company that delivers solutions to power our industrial customers' digital transformations, enabling them to better design, manufacture, operate, and service their products. Our Internet of Things (IoT) and Augmented Reality (AR) solutions enable companies to connect factories and plants, smart products, and enterprise systems to transform their businesses. These products, along with Onshape and Arena, are considered our Growth Products. The primary products in our Core Products portfolio are innovative Computer-Aided Design (CAD) and Product Lifecycle Management (PLM) solutions that enable manufacturers to create, innovate, and service products. Our Focused Solutions Group (FSG) is a family of software products that target specific vertical industries where we can deliver unique domain expertise and a competitive advantage with Application Lifecycle Management (ALM) products, Service Lifecycle Management (SLM) products, and other niche tailored solutions. Together, these technologies power the digital thread across industrial enterprises.

Forward-Looking Statements

Statements in this document that are not historic facts, including statements about our future financial and growth expectations and targets, debt repayment and potential stock repurchases, are forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those projected. These risks include: the macroeconomic and/or global manufacturing climates may not improve when or as we expect, or may deteriorate, due to, among other factors, the COVID-19 pandemic, which could cause customers to delay or reduce purchases of new software, reduce the number of subscriptions they carry, or delay payments to us, all of which would adversely affect ARR and our financial results, including cash flow; our businesses, including our SaaS businesses, may not expand and/or generate the revenue or ARR we expect if customers are slower to adopt our technologies than we expect or if they adopt competing technologies; we may be unable to generate sufficient operating cash flow to repay our outstanding debt when or as we expect or to return 50% of free cash flow to shareholders, and other uses of cash or our credit facility limits or other matters could preclude such repayment and/or repurchases; foreign exchange rates may differ materially from those we expect; and orders associated with minimum purchase commitments under our Strategic Alliance Agreement with Rockwell Automation may not result in subscription contracts sold through to end-user customers, which could cause the ARR associated with those orders to churn. In addition, our assumptions concerning our future GAAP and non-GAAP effective income tax rates are based on estimates and other factors that could change, including the geographic mix of our revenue, expenses, and profits. Other risks and uncertainties that could cause actual results to differ materially from those projected are described below throughout or referenced in Part II, Item 1A. Risk Factors of this report.

Operating and Non-GAAP Financial Measures

Our discussion of results includes discussion of our ARR (Annual Run Rate) operating measure, non-GAAP financial measures, and disclosure of our results on a constant currency basis. ARR and our non-GAAP financial measures, including the reasons we use those measures, are described below in Results of Operations - Operating Measure and Results of Operations - Non-GAAP Financial Measures, respectively. The methodology used to calculate constant currency disclosures is described in Results of Operations - Impact of Foreign Currency Exchange on Results of Operations. You should read those sections to understand our operating measure, non-GAAP financial measures, and constant currency disclosures.

Executive Overview

ARR of $1.39 billion represents 18% growth (15% on a constant currency basis) compared to Q2’20 driven by a combination of strong results in our Growth business, continued momentum in our Core business, and strong performance from Arena Solutions in its first quarter as part of PTC. Organic ARR growth year over year was 14% (11% constant currency). Second quarter revenue was up 28% year over year (22% constant currency), driven by strong execution as well as the impact of up-front license revenue recognition under ASC 606 and a modest contribution from Arena. Organic revenue growth year over year was 26% (20% constant currency).

Our Q2’21 operating margin increased over 800 bps compared to Q2’20, primarily due to strong revenue growth, as well as continued financial discipline. Our Q2’21 diluted EPS of $0.92 was up

Table of Contents

significantly compared to $0.06 in Q2’20, which reflect s those same factors, as well as the recognition of a $42 million tax benefit related to the Arena acquisition and lower interest expense.

In Q2’21, we acquired Arena Solutions for approximately $715 million, net of cash acquired. Arena contributed approximately $54 million of ARR and an immaterial amount of revenue to our Q2’21 results.

We generated $122 million of cash from operations in Q2'21 compared to $88 million in Q2'20, primarily reflecting higher collections and lower restructuring payments. We ended Q2’21 with $326 million of cash and cash equivalents and $1.5 billion of debt outstanding with a weighted average cost of debt of 3.1%.

Future Expectations

Our results have been impacted, and we expect will continue to be impacted, by our ability to close large transactions. Additionally, under the subscription license model, particularly sales of products in our growth business, customers may place smaller initial orders than under a perpetual license model. Sales of our products may have long lead times as they often follow a lengthy product selection and evaluation process and, for existing customers, are influenced by contract duration and expiration cycles. Accordingly, the amount of revenue attributable to large transactions, and the number of such transactions, may vary significantly from quarter to quarter based on customer purchasing decisions and macroeconomic conditions. This may cause volatility in our results.

Despite the challenges associated with the COVID-19 pandemic, we currently anticipate ARR, revenue, and operating margin growth in FY’21. We expect organic churn to improve slightly compared to FY’20.

Results of Operations

The following table shows the financial measures that we consider the most significant indicators of our business performance. In addition to providing operating income, operating margin, diluted earnings per share and cash from operations as calculated under GAAP, we provide non-GAAP operating income, non-GAAP operating margin, non-GAAP diluted earnings per share, and free cash flow for the reported periods. We also provide a view of our actual results on a constant currency basis. These non-GAAP financial measures exclude the items described in Non-GAAP Financial Measures below. Investors should use these non-GAAP financial measures only in conjunction with our GAAP results.

(1) | Recurring revenue is comprised of subscription, perpetual support, SaaS, and cloud revenue.

(2) | See Non-GAAP Financial Measures below for a reconciliation of our GAAP results to our non-GAAP measures and Impact of Foreign Currency Exchange on Results of Operations below for a description of how we calculate our results on a constant currency basis.

(3) | We have recorded a full valuation allowance against our U.S. net deferred tax assets. As we are profitable on a non-GAAP basis, the FY’21 and FY’20 non-GAAP tax provisions are being calculated assuming there is no valuation allowance. In Q2’21 and Q1'20, our GAAP results included benefits of $42.3 million and $21.2 million, respectively, related to the release of a valuation allowance as a result of the Arena and Onshape acquisitions. As the non-GAAP tax provision is calculated assuming that there is no valuation allowance, these benefits have been excluded. Income tax adjustments reflect the tax effects of non-GAAP adjustments which are calculated by applying the applicable tax rate by jurisdiction to the non-GAAP adjustments listed above. Additionally, our non-GAAP results for the first six months of FY’21 exclude tax expense of $34.2 million related to a non-U.S. tax exposure described in Note 12. Income Taxes to the Financial Statements.

(4) | Cash flow from operations for the second quarter and first six months of FY’21 includes $4.5 million and $11.7 million of restructuring payments, respectively, and $8.2 million and $11.1 million of acquisition-related payments, respectively. Cash flow from operations for the second quarter and first six months of FY’20 includes $18.0 million and $21.3 million of restructuring payments, respectively, and $2.1 million and $8.6 million of acquisition-related payments, respectively.

(5) | Free cash flow is cash from operations net of capital expenditures of $5.4 million and $8.2 million in the second quarter and first six months of FY’21, respectively, and $5.5 million and $10.2 million in the second quarter and first six months of FY’20, respectively.

Impact of Foreign Currency Exchange on Results of Operations

Approximately 60% of our revenue and 40% of our expenses are transacted in currencies other than the U.S. Dollar. Because we report our results of operations in U.S. Dollars, currency translation, particularly changes in the Euro, Yen, Shekel, and Rupee relative to the U.S. Dollar, affects our reported results. Our constant currency disclosures are calculated by multiplying the results in local currency for the quarterly and year-to-date periods for FY’21 and FY’20 by the exchange rates in effect on September 30, 2020. The results of operations in the table above and revenue by line of business, product group, and geographic region in the tables that follow present both actual percentage changes year over year and percentage changes on a constant currency basis.

Revenue

Our revenue results quarter to quarter are impacted by contract terms, including the duration and start dates of our subscription contracts, due to our up-front recognition of subscription license revenue. We are expanding our SaaS offerings and are releasing additional cloud functionality into our products. As a result, our revenue will be impacted over time as a higher portion of it will be recognized ratably.

Software revenue in the second quarter and first six months of FY’21 increased compared to the year-ago periods due to subscription revenue growth, partially offset by a decline in perpetual support revenue due to conversions of support contracts to subscriptions. License revenue growth was primarily driven by contracts with longer durations. Subscription support and cloud services revenue in the second quarter and first six months of FY’21 grew 39% (34% constant currency) and 38% (34% constant currency), respectively, compared to the year-ago periods, while perpetual support revenue decreased 19% (22% constant currency) and 16% (19% constant currency), primarily due to conversions of perpetual support contracts to subscriptions.

Professional services engagements typically result from sales of new licenses; revenue is recognized over the term of the engagement. Our expectation is that professional services revenue will trend flat-to-down over time due to our strategy to expand margins by migrating more services engagements to our partners and delivering products that require less consulting and training services.

Professional services revenue growth in Q2’21 compared to Q2’20 is partially due to a Q2’20 revenue reversal related to an extension to complete work on a large fixed price professional services contract in that period, as well as the start of new contracts in Q2’21. In the first six months of FY’21, professional services revenue declined due to challenges with project scoping and implementation activities and performance due to social distancing measures and facility closures implemented to address the COVID-19 pandemic, as well as the end of a few large projects.

Operating expenses in Q2’21 compared to operating expenses in Q2’20 increased primarily due to the following:

| • | a $47.8 million increase in compensation expense (including benefit costs), primarily driven by a $22.8 million (130%) increase in stock-based compensation expense, a $12.7 million (13%) increase in salaries due in part to the Arena acquisition, and a $5.6 million increase in bonus expense;

| • | a $10.0 million increase in acquisition-related transaction costs, included in general and administrative; and

| • | a $2.8 million increase in cloud services hosting costs;

partially offset by:

| • | a $17.8 million decrease in restructuring costs; and

| • | a $4.2 million decrease in travel costs due to the COVID-19 pandemic.

Operating expenses in the first six months of FY’21 compared to operating expenses in the first six months of FY’20 increased primarily due to the following:

| • | an $82.4 million increase in compensation expense (including benefit costs), primarily driven by a $39.5 million (93%) increase in stock-based compensation expense, a $23.9 million (13%) increase in salaries due in part to the Arena acquisition, and a $6.8 million (185%) increase in bonus expense;

| • | a $6.8 million increase in acquisition-related transaction costs, included in general and administrative;

| • | a $4.6 million increase in cloud services hosting costs; and

| • | $3.8 million of expenses related to our investment in our digital transformation;

partially offset by:

| • | a $31.6 million decrease in restructuring costs; and

| • | a $9.8 million decrease in travel costs due to the COVID-19 pandemic.

Stock-based compensation was higher in FY’21 compared to FY’20 primarily due to higher estimated attainment under performance-based awards. In addition, an increase in time-based award grants in FY’20 and expected higher stock-based bonus attainment in FY’21 increased expense. Non-stock based bonus expense was also higher in FY’21 compared to FY’20 due higher estimated attainment under the FY’21 bonus plan.

In the second quarter and first six months of FY’21 and FY’20, our effective tax rate differed from the statutory federal income tax rate of 21% due to U.S. tax reform, our corporate structure in which our foreign taxes are at a net effective tax rate lower than the U.S. rate, and the excess tax benefit related to stock-based compensation. A significant amount of our foreign earnings is generated by our subsidiaries organized in Ireland. In FY’21 and FY’20, the foreign rate differential predominantly relates to these Irish earnings. In addition, the effective tax rate was impacted by the matters described below.

Our results for the six months ended March 31, 2021 include a charge of $36.1 million related to the effects of an unrecognized tax benefit in a non-U.S. jurisdiction. See Note 12. Income Taxes to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q for additional information about this charge.

In the second quarter of FY’21, we reduced our previously established U.S. valuation allowance by $42.3 million as a result of the Arena acquisition. In the first six months of FY’20, we reduced our previously established U.S. valuation allowance by $21.2 million as a result of the Onshape acquisition.

ARR (Annual Run Rate) ARR represents the annualized value of our portfolio of active subscription software, cloud, SaaS, and support contracts as of the end of the reporting period. ARR includes orders placed under our Strategic Alliance Agreement with Rockwell Automation, including orders placed to satisfy contractual minimum commitments.

We believe ARR is a valuable operating metric to measure the health of a subscription business because it captures expected subscription and support cash generation from customers. Because this measure represents the annualized value of customer contracts as of a point in time, it does not represent revenue for any particular period or remaining revenue that will be recognized in future periods.

Non-GAAP Financial Measures

Our non-GAAP financial measures and the reasons we use them and the reasons we exclude the items identified below are described in Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended September 30, 2020.

Table of Contents

The non-GAAP financial measures presented in the discussion of our results of operations and the respective most directly comparable GAAP measures are:

| • | free cash flow—cash flow from operations

| • | non-GAAP gross margin—GAAP gross margin

| • | non-GAAP operating income—GAAP operating income

| • | non-GAAP operating margin—GAAP operating margin

| • | non-GAAP net income—GAAP net income

| • | non-GAAP diluted earnings or loss per share—GAAP diluted earnings or loss per share

Free cash flow is cash flow from operations net of capital expenditures, which are expenditures for property and equipment and consist primarily of facility improvements, office equipment, computer equipment, and software. We believe that free cash flow, in conjunction with cash from operations, is a useful measure of liquidity since capital expenditures are a necessary component of ongoing operations.

The non-GAAP financial measures other than free cash flow exclude, as applicable: stock-based compensation; amortization of acquired intangible assets; acquisition-related and other transactional charges included in general and administrative expenses; restructuring and other charges, net; certain non-operating charges; and income tax adjustments. Additional information about the items we exclude from our non-GAAP financial measures and the reasons we exclude them can be found in Non-GAAP Financial Measures on page 25 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. In the first six months of FY’21, we incurred tax expense related to a reserve for a South Korean tax exposure established in the period which is excluded from our non-GAAP financial measures as it is related to prior periods and not included in management’s view of Q2’21 results for comparative purposes. In Q2’21, we incurred a tax benefit related to the release of a valuation allowance as a result of the Arena acquisition. As the non-GAAP tax provision is calculated assuming that there is no valuation allowance, this benefit has been excluded from our non-GAAP financial measures.

The items excluded from these non-GAAP financial measures are normally included in the comparable measures calculated and presented in accordance with GAAP. Our management excludes these items when evaluating our ongoing performance and/or predicting our earnings trends, and therefore excludes them when presenting non-GAAP financial measures. Management uses non-GAAP financial measures in conjunction with our GAAP results, as should investors.

The items excluded from the non-GAAP financial measures often have a material impact on our financial results, certain of those items are recurring, and other such items often recur. Accordingly, the non-GAAP financial measures included in this Quarterly Report on Form 10-Q should be considered in addition to, and not as a substitute for or superior to, the comparable measures prepared in accordance with GAAP. The following tables reconcile each of these non-GAAP financial measures to its most closely comparable GAAP measure on our financial statements.

(1) | We recognized $15 million of expense in Q2’20 related to penalties for the early redemption of the 6.000% Senior Notes due in 2024.

(2) | We have recorded a full valuation allowance against our U.S. net deferred tax assets. As we are profitable on a non-GAAP basis, the FY’21 and FY’20 non-GAAP tax provisions are being calculated assuming there is no valuation allowance. In Q2’21 and Q1'20, our GAAP results included benefits of $42.3 million and $21.2 million, respectively, related to the release of a valuation allowance as a result of the Arena and Onshape acquisitions. As the non-GAAP tax provision is calculated assuming that there is no valuation allowance, these benefits have been excluded. Income tax adjustments reflect the tax effects of non-GAAP adjustments which are calculated by applying the applicable tax rate by jurisdiction to the non-GAAP adjustments listed above. Additionally, our non-GAAP results for the first six months of FY’21 exclude tax expense of $34.2 million related to the non-U.S. tax exposure described in Note 12. Income Taxes to the Financial Statements.

Recent Accounting Pronouncements

In accordance with recently issued accounting pronouncements, we will be required to comply with certain changes in accounting rules and regulations. Refer to Note 1. Basis of Presentation to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q, which is incorporated herein by reference, for all recently issued accounting pronouncements.

Cash, Cash Equivalents and Restricted Cash

We invest our cash with highly rated financial institutions. Cash and cash equivalents include highly liquid investments with original maturities of three months or less. In December 2020, we sold all our marketable securities. At March 31, 2021, cash and cash equivalents totaled $326 million, compared to $275 million at September 30, 2020.

A significant portion of our cash is generated and held outside the U.S. As of March 31, 2021, we had cash and cash equivalents of $44 million in the U.S., $141 million in Europe, $109 million in Asia Pacific (including India) and $32 million in other non-U.S. countries. We have substantial cash requirements in the U.S., but we believe that the combination of our existing U.S. cash and cash equivalents, our ability to repatriate cash to the U.S. more cost effectively with the recent U.S. tax law changes, future U.S. operating cash flows, and cash available under our credit facility will be sufficient to meet our ongoing U.S. operating expenses and known capital requirements.

Cash Provided by Operating Activities

Cash provided by operating activities was $235 million in the first six months of FY’21, compared to $95 million in the first six months of FY’20. Cash from operations for the first six months of FY’21 includes $11.7 million of restructuring payments and $11.1 million of acquisition-related payments compared to $21.3 million of restructuring payments and $8.6 million of acquisition-related payments in the prior-year period. The increase in cash from operations in the first six months of FY’21 compared to the same period in FY’20 was primarily driven by increased collections, offset by higher compensation payments.

Cash used in investing activities in the first six months of FY’21 reflects approximately $71 5 million used for the Arena acquisition and $56 million in proceeds from the sale of marketable securities. Cash used in investing activities in the first six months of FY’20 reflects $469 million used for the Onshape acquisition.

Cash Provided by Financing Activities

Net cash provided by financing activities |  | $ | 485.0 |  |  | $ | 944.1 |

Cash provided by financing activities in the first six months of FY’21 reflects net borrowings of $502 million under our credit facility, compared to net borrowings of $975 million in the first six months of FY’20, primarily related to the issuance of the 4.000% Senior Notes due 2028 and 3.625% Senior Notes due 2025 in Q2’20.

Outstanding Debt

(in millions) |  | March 31, 2021 |
4.000% Senior notes due 2028 |  | $ | 500.0 |
3.625% Senior notes due 2025 |  |  | 500.0 |
Credit facility revolver |  |  | 520.0 |
Total debt |  | $ | 1,520.0 |
Unamortized debt issuance costs for the senior notes |  |  | (11.6 | )
Total debt, net of issuance costs |  | $ | 1,508.4 |
Undrawn under credit facility revolver |  | $ | 480.0 |
Undrawn under credit facility revolver available to borrow |  | $ | 463.7 |

As of March 31, 2021, we were in compliance with all financial and operating covenants of the credit facility and the note indentures. Any failure to comply with such covenants under the credit facility would prevent us from being able to borrow additional funds under the credit facility, and, as with any failure to comply with such covenants under the note indentures, could constitute a default that could cause all amounts outstanding to become due and payable immediately.

Our credit facility and our senior notes are described in Note 13. Debt to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q.

Future Expectations

We believe that existing cash and cash equivalents, together with cash generated from operations and amounts available under our credit facility, will be sufficient to meet our working capital and capital expenditure requirements (which capital expenditures we expect to be approximately an additional $15 million in FY’21) through at least the next twelve months and to meet our known long-term capital requirements.

In January 2021, we acquired Arena Solutions for approximately $715 million, net of cash acquired. In connection with the acquisition, we borrowed $600 million under our existing credit facility. We plan to use available cash from operations to pay down borrowings under the credit facility. We intend to continue targeting a leverage ratio (Debt/EBITDA) of below 3x and will assess share repurchases in that context.

Our expected uses and sources of cash could change, payments due to us may be delayed due to the COVID-19 pandemic, our cash position could be reduced, and we could incur additional debt obligations if we decide to retire debt, engage in strategic transactions or repurchase shares, any of which could be commenced, suspended or completed at any time. Any such repurchases or retirement of debt will depend on prevailing market conditions, our liquidity requirements, contractual restrictions

and other factors. The amounts involved in any debt retirement or issuance, share repurchases, or strategic transactions may be material.

ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no significant changes in our market risk exposure as described in Item 7A. Quantitative and Qualitative Disclosures about Market Risk of our 2020 Annual Report on Form 10-K.

ITEM 4. | CONTROLS AND PROCEDURES

Evaluation of Effectiveness of Disclosure Controls and Procedures

Our management maintains 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”) that are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), as appropriate, to allow for timely decisions regarding required disclosure.

We evaluated, under the supervision and with the participation of management, including our principal executive and principal financial officers, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2021.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in management's evaluation pursuant to Rules 13a or 15(d) of the Exchange Act that occurred during the period ended March 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
