NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.Organization and description of business

Altair Engineering Inc. (“Altair” or the “Company”) is incorporated in the state of Delaware. The Company is a global leader in computational science and artificial intelligence (”AI”) that provides software and cloud solutions in simulation, high-performance computing (“HPC”), data analytics, and AI. Altair enables organizations across all industries to compete more effectively and drive smarter decisions in an increasingly connected world - all while creating a greener, more sustainable future. The Company is headquartered in Troy, Michigan.

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2021, included in the most recent Annual Report on Form 10-K filed with the SEC.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.

Significant accounting policies

There have been no material changes to our significant accounting policies as of and for the six months ended June 30, 2022, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2021.

2.Recent accounting guidance

Accounting standards adopted

Debt – In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020-06, a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The Company adopted ASU 2020-06 effective as of January 1, 2022, using the modified retrospective approach. Adoption of the new standard resulted in a decrease to accumulated deficit of $23.9 million, a decrease to additional paid-in capital of $50.0 million, and an increase to convertible senior notes, net of $26.1 million. Interest expense recognized in the current and future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost.

9

Accounting standards not yet adopted

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. This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are optional and effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Government Assistance – In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This ASU requires certain disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The amendment requires disclosure of information about the nature of the transactions and the related accounting policy used to account for the transactions, information regarding the line items within the consolidated financial statements that are affected by the transactions, and significant terms and conditions of the transactions. ASU 2021-10 is effective for annual periods beginning after December 15, 2021, with early application permitted. The Company is currently evaluating the effect the adoption of this new guidance will have on its consolidated financial statement disclosures.

Stock repurchase program

In February 2022, the Company’s Board of Directors approved a stock repurchase program to repurchase up to $50.0 million of the Company’s Class A Common Stock. Purchases under the stock repurchase program may be made from time to time in the open market at prevailing prices, or through privately negotiated transactions. The Company is not obligated to repurchase any dollar amount or number of shares, and the stock repurchase program may be suspended or terminated at any time. All shares repurchased under the stock repurchase program are retired.

During the period ended June 30, 2022, under our stock repurchase program, we repurchased 85,119 shares at an average price of $51.52 per share for a total cost of $4.4 million. As of June 30, 2022, $45.6 million of shares of Class A Common Stock remained available for repurchase under the program.

Mezzanine equity

In 2017, the Company issued 200,000 shares of Class A Common Stock to a third-party as partial consideration for the purchase of developed technology. These shares had a put right that could be exercised by the holder five years from date of purchase at $12.50 per share that required the shares to be recorded at issuance date fair value and classified as mezzanine equity in the consolidated balance sheet.

During the year ended December 31, 2020, the third-party holder sold 133,336 shares on the open market and as a result, the issuance date fair value of those shares was reclassified into permanent equity from mezzanine equity. As of June 30, 2022, the put right has lapsed and the issuance date fair value of the remaining 66,664 shares were reclassified into permanent equity from mezzanine equity.

Restructuring expense

In 2021, the Company initiated a restructuring plan to realign resources with the Company’s business outlook and cost structure. The restructuring plan resulted in charges for employee termination benefits of $1.7 million and $5.1 million for the three and six months ended June 30, 2021, respectively. There were no restructuring costs for the three and six months ended June 30, 2022. The restructuring costs were attributable primarily to the Software reportable segment. The restructuring plan was completed, and all amounts were paid in 2021.

5.Acquisitions

2022 Acquisitions

Concept Engineering

In June 2022, the Company entered into a stock purchase agreement and simultaneously acquired 100% of the outstanding capital stock of Concept Engineering, a leading provider of electronic system visualization software that accelerates the development, manufacture, and service of complex electrical and electronic systems, for preliminary aggregate consideration of $25.7 million. See Note 9 for further information on this acquisition. Concept Engineering’s software will be integrated into Altair’s Electronic System Design suite and will be available via Altair Units.

The acquisition of Concept Engineering will be accounted for as a business combination under the acquisition method of accounting. As of June 30, 2022, the book value of assets acquired and liabilities assumed were reported in the Company’s consolidated balance sheet. The remaining purchase price of $22.7 million has been recorded in goodwill pending fair value allocation. All goodwill is recorded in the Software segment.

The primary areas that remain preliminary relate to the fair value of intangible assets acquired, certain tangible assets and liabilities acquired, income taxes and residual goodwill. The Company expects to finalize the valuation as soon as practicable, but not later than one year from the acquisition date.

Other business acquisitions

During the six months ended June 30, 2022, the Company completed three other business acquisitions that will be accounted for as business combinations under the acquisition method for preliminary transaction consideration of $18.0 million. As of June 30, 2022, $7.8 million of preliminary consideration for two of these acquisitions was reported in goodwill in the consolidated balance sheet pending fair value allocation. All goodwill is recorded in the Software segment. The Company expects to finalize the valuations as soon as practicable, but not later than one year from the acquisition dates. These acquisitions were not material to the Company’s consolidated financial statements.

The operating results of each acquisition have been included in the consolidated financial statements since the respective dates of acquisition. The Company’s transaction costs related to its 2022 acquisitions were not material.

2021 Acquisitions

World Programming

In December 2021, the Company acquired all of the outstanding capital stock of two related privately held companies, World Programming Limited and December 2015 Software Limited (together “World Programming”), from the stockholders named therein, for preliminary aggregate consideration of $73.0 million. The preliminary consideration consisted of cash in the amount of $50.0 million, subject to a customary working capital adjustment, and contingent consideration of $23.0 million, including $19.5 million of the Company’s Class A Common Stock (the “Contingent Stock Consideration”) and a measurement period adjustment of $3.5 million recognized in 2022. The dates on which the Contingent Stock Consideration is issuable and the number of shares issuable on such dates depend primarily on certain aspects of legal proceedings in which World Programming and SAS Institute, Inc. are engaged. For further information on the legal proceedings see Note 13.

The Company is required to mark-to-market the Contingent Stock Consideration liability based on the trading price of the Company’s Class A Common Stock. For the three and six months ended June 30, 2022, the Company recognized a gain of $5.3 million on the mark-to-market adjustment of contingent consideration which is included in Other operating income, net in the consolidated statements of operations.

In addition, per the stock purchase agreement, $29.5 million of Class A Common Stock will be issued subject to the continuing employment of certain key employees and are not reflected in aggregate consideration but will be recognized as stock-based compensation over the service period of three years.

As of June 30, 2022, Other accrued expenses and current liabilities included $0.4 million of contingent consideration due to employees.

14

The acquisition has been accounted for as a business combination under the acquisition method of accounting, which results in acquired assets and assumed liabilities being measured at their estimated fair value as of the acquisition date. The following table summarizes the preliminary purchase consideration transferred to acquire World Programming and the amounts of identified assets acquired and liabilities assumed at the acquisition date (in thousands):

Fair value of consideration transferred	$	73,043
Recognized amounts of identifiable assets acquired and liabilities assumed:
Cash		1,895
Accounts receivable		5,656
Other assets		6,085
Property and equipment		2,209
Trade names (4-year life)		300
Developed technology (5-year life)		33,000
Customer relationships (7-year life)		7,000
SAS legal liability		(66,596	)
Accounts payable and other liabilities		(3,401	)
Deferred revenue		(2,737	)
Deferred tax liabilities and other tax reserves		(11,406	)
Total net identifiable assets acquired and liabilities assumed		(27,995	)
Goodwill (1)	$	101,038

(1)Goodwill is primarily attributable to market synergies expected to arise after the acquisition and is not deductible for tax purposes. All goodwill is recorded in the Software segment.

The preliminary estimated fair values of assets acquired and liabilities assumed, and identifiable intangible assets may be subject to change as additional information is received. The valuation was complex due to the significant estimation uncertainty in certain assumptions used to determine the fair value of intangible assets acquired and contingent consideration. The Company continues to collect information with regard to its estimates and assumptions, including the fair value of intangible assets acquired, certain tangible assets and liabilities acquired, contingent consideration, income taxes and residual goodwill. The Company expects to finalize the valuation as soon as practicable, but not later than one year from the acquisition date.

7.Debt

Convertible senior notes

2027 Notes

In June 2022, the Company issued $230.0 million aggregate principal amount of 1.750% convertible senior notes due in 2027 (the "2027 Notes"), which includes the initial purchaser’s exercise in full of its option to purchase an additional $30.0 million principal amount of the 2027 Notes, in a private offering. The net proceeds from the issuance of the 2027 Notes was $224.3 million after deducting discounts, commissions and estimated issuance costs.

The Company entered into an Indenture relating to the issuance of the 2027 Notes dated June 14, 2022 (the “Indenture”), by and between the Company and U.S. Bank Trust Company, National Association, as trustee. The Indenture includes customary covenants and sets forth certain events of default after which the 2027 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the 2027 Notes become automatically due and payable. The 2027 Notes are senior unsecured obligations of the Company.

The 2027 Notes mature on June 15, 2027, unless earlier repurchased, redeemed or converted. The Company may redeem for cash all or, subject to certain limitations, any portion of the 2027 Notes, at its option, on or after June 20, 2025 if the last reported sale price of Altair's Class A Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. The 2027 Notes bear interest at a rate of 1.750% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2022.

16

The 2027 Notes have an initial conversion rate of 13.9505 shares of the Company's Class A common stock per $1,000 principal amount of 2027 Notes, which is equivalent to an initial conversion price of approximately $71.68 per share of Class A common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events specified in the Indenture but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of a make whole fundamental change or a redemption period (each as defined in the Indenture), the Company will, in certain circumstances, increase the conversion rate by a specified number of additional shares for a holder who elects to convert its 2027 Notes in connection with such make whole fundamental change or during the relevant redemption period.

Holders of the 2027 Notes may convert all or any portion of their 2027 Notes at any time prior to the close of business on the business day immediately preceding December 15, 2026, in integral multiples of $1,000 principal amount, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on September 30, 2022, if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

17

•during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of the 2027 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Class A Common Stock and the conversion rate on each such trading day;

•if the Company calls the 2027 Notes for redemption (which the Company may not do prior to June 20, 2025), at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date but only with respect to the 2027 Notes called (or deemed called) for redemption; or

•upon the occurrence of specified corporate events.

On or after December 15, 2026 until the close of business on the business day immediately preceding the maturity date, holders may convert their 2027 Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of Class A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture.

During the period ended June 30, 2022, the conditions allowing holders of the 2027 Notes to convert were not met. Therefore, the 2027 Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2022.

2024 Notes

In June 2019, the Company issued $230.0 million aggregate principal amount of 0.25% convertible senior notes due in 2024 (the "2024 Notes" and together with the 2027 Notes, the “Convertible Notes”), which includes the underwriters’ exercise in full of their option to purchase an additional $30.0 million principal amount of the 2024 Notes, in a public offering. The net proceeds from the issuance of the 2024 Notes were $221.9 million after deducting the underwriting discounts and commissions and estimated issuance costs. The 2024 Notes bear interest at a rate of 0.25% per year, payable semi-annually in arrears on June 1 and December 1 of each year, commencing December 1, 2019. The 2024 Notes mature on June 1, 2024, unless, earlier repurchased or redeemed by the Company or converted pursuant to their terms. The 2024 Notes have an initial conversion rate of 21.5049 shares of the Company's Class A common stock per $1,000 principal amount of 2024 Notes, which is equivalent to an initial conversion price of approximately $46.50 per share of its Class A common stock. Refer to the Company’s consolidated financial statements for the year ended December 31, 2021, for details of the issuance of the 2024 Notes.

Prior to January 1, 2022, the Company separated the 2024 Notes into liability and equity components. On issuance, the carrying amount of the equity component was recorded as a debt discount and subsequently amortized to interest expense. Effective January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective approach. As a result, the 2024 Notes are accounted for as a single liability measured at amortized cost, as no other embedded features require bifurcation and recognition as derivatives. Adoption of the new standard resulted in a decrease to Accumulated deficit of $23.9 million, a decrease to Additional paid-in capital of $50.0 million, and an increase to Convertible senior notes, net of $26.1 million.

During the three months ended June 30, 2022, using proceeds from the issuance of the 2027 Notes, the Company entered into separate privately negotiated transactions with certain holders of the 2024 notes to repurchase and retire $148.2 million aggregate principal amount of the 2024 notes for an aggregate amount of $192.4 million of cash including accrued and unpaid interest. The Company recognized expense of $16.6 million, representing the fair value of the consideration paid to certain holders of the 2024 Notes in excess of the value to which they were entitled to receive on the respective settlement dates. The amount is included in Other expense, net in the Company’s consolidated statement of operations.

As of June 30, 2022, $81.8 million principal amount of the 2024 Notes remained outstanding. The Company may settle the 2024 Notes in cash, shares of Class A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election.

18

During the period ended June 30, 2022, the conditions allowing holders of the 2024 Notes to convert were not met. Therefore, the 2024 Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2022. As of December 31, 2021, the conditions allowing the holders of the 2024 Notes to convert were met. Therefore, the 2024 Notes were classified as current on the consolidated balance sheet as of December 31, 2021.

The Convertible Notes consisted of the following (in thousands):

	June 30, 2022				December 31, 2021
	2027 Notes		2024 Notes		2027 Notes		2024 Notes

(1)The Company adopted ASU 2020-06 on January 1, 2022, which resulted in the convertible notes to be accounted for as a single liability.

The interest expense recognized related to the Convertible Notes was as follows (in thousands):

	Three Months Ended  June 30,				Six Months Ended June 30,
	2022		2021		2022		2021

Total	$	600	$	2,975	$	1,156	$	5,913

(1)The 2021 amount includes the amortization of the debt discount prior to the adoption of ASU 2020-06 of January 1, 2022.

As of June 30, 2022, the if converted value of the 2027 Notes did not exceed the principal amount. As of June 30, 2022, the if converted value of the 2024 Notes exceeded the principal amount by $10.5 million.

Credit agreement

Revolving credit facility

The Company has a $150.0 million credit facility with a maturity date of December 15, 2025 (“2019 Amended Credit Agreement”). The 2019 Amended Credit Agreement provides for an accordion feature that allows the Company to expand the size of the revolving line of credit by an additional $50.0 million, subject to certain conditions, by obtaining additional commitments from the existing lenders or by causing a person acceptable to the administrative agent to become a lender (in each case subject to the terms and conditions set forth in the 2019 Amended Credit Agreement). In June 2022, the Company amended the 2019 Amended Credit Agreement to, among other things, permit the issuance of the 2027 Notes and extend the maturity date of the credit facility to December 2025.

As of June 30, 2022, there were no outstanding borrowings under the 2019 Amended Credit Agreement, there was $150.0 million available for future borrowing, and the Company was in compliance with all the financial covenants. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures, and permitted acquisitions.

For additional information about the 2019 Amended Credit Agreement, refer to the Company’s consolidated financial statements for the year ended December 31, 2021, included in our Annual Report on Form 10-K for the year ended December 31, 2021.

8.Fair value measurements

19

The accounting guidance for fair value, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The framework for measuring fair value consists of a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows:

Level 1 – Quoted prices in active markets for identical assets and liabilities at the measurement date;

Level 2 – Observable inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The carrying value of cash and cash equivalents, accounts receivable, net and accounts payable approximate fair value due to their short maturities. Interest on the Company’s line of credit is at a variable rate, and as such the debt obligation outstanding approximates fair value.

The carrying value of the Company’s Convertible Notes are at face value less unamortized debt discount and issuance costs. The estimated fair values of the Convertible Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the Convertible Notes on the last trading day of each reporting period. As of June 30, 2022, the estimated fair value of the 2027 Notes and 2024 Notes was $224.0 million and $101.3 million, respectively, and is presented for required disclosure purposes only. For further information on the Convertible Notes, see Note 7. – Debt.

In 2017, the Company’s board of directors adopted the 2017 Equity Incentive Plan (“2017 Plan”), which was approved by the Company’s stockholders. The 2017 Plan provides for the grant of incentive stock options to the Company’s employees and any parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares, other cash-based awards and other stock-based awards to the Company’s employees, directors and consultants and the Company’s parent, subsidiary, and affiliate corporations’ employees and consultants. The 2017 Plan has 16,999,318 authorized shares of the Company’s Class A common stock reserved for issuance.

The following table summarizes the restricted stock units, or RSUs, awarded under the 2017 Plan for the period:

	Number of RSUs
Outstanding as of January 1, 2022		1,281,411
Granted		435,614
Vested		(366,667	)
Forfeited		(19,008	)
Outstanding as of June 30, 2022		1,331,350

The weighted average grant date fair value of the RSUs was $57.21 and the RSUs generally vest in four equal annual installments. Total compensation cost related to nonvested awards not yet recognized as of June 30, 2022, totaled $70.4 million, and is expected to be recognized over a weighted average period of 2.6 years.

The following table summarizes the stock option activity under the 2017 Plan for the period:

	Number of options			Weighted average exercise price per share		Weighted average remaining contractual term (years)		Aggregate  intrinsic value  (in millions)
Outstanding as of January 1, 2022		4,875,562		$	51.02		8.8
Granted		885,262		$	56.26
Exercised		(32,038	)	$	41.44

Outstanding as of June 30, 2022		5,671,060		$	51.96		8.6	$	27.7
Exercisable as of June 30, 2022		1,037,227		$	40.58		7.9	$	12.8

The total intrinsic value of the 2017 Plan stock options exercised during the six months ended June 30, 2022, was $0.4 million.

2021 Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan (“ESPP”) which allows eligible employees to purchase shares of common stock through payroll deductions and is intended to qualify under Section 423 of the Internal Revenue Code. As of June 30, 2022, the Company had 3,123,191 shares of its common stock available for future issuances under the ESPP.

The purchase price for each share of common stock purchased under the ESPP will be 85% of the lower of (a) the fair market value per share on the first day of the applicable offering period or (b) the fair market value per share on the applicable purchase date.

The Company purchased 76,809 shares of common stock under the ESPP during the six months ended June 30, 2022. As of June 30, 2022, $4.4 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions and is reported in Other accrued expenses and current liabilities. The Company recognized $0.6 million and $1.3 million of stock-based compensation expense related to the ESPP for the three and six months ended June 30, 2022, respectively.

Other

In connection with the acquisition of World Programming in December 2021, per the stock purchase agreement, $29.5 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one-, two- and three-year anniversaries of the certain legal matters being resolved, subject to potential reduction in certain circumstances. The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration.

The estimated post combination expense to the Company as a result of the World Programming business combination was $29.5 million which is recognized on an accelerated method over the employment period. As of June 30, 2022, the weighted average remaining service period is 2.5 years. Once the vesting conditions of the service period are met, the Company will issue shares for each award. Stock-based compensation expense includes $4.5 million and $8.9 million for the three and six months ended June 30, 2022, respectively.

In connection with the acquisition of Powersim Inc. in March 2022, per the stock purchase agreement, $4.3 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one - and two-year anniversaries of certain matters being resolved, subject to potential reduction in certain circumstances. The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration. Stock-based compensation expense includes $0.9 million and $1.1 million for the three and six months ended June 30, 2022, respectively.

In connection with the acquisition of Concept Engineering in June 2022, per the stock purchase agreement, $6.0 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one, and two-year anniversaries of certain matters being resolved, subject to potential reduction in certain circumstances. The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration. Stock-based compensation expense includes $0.2 million for both the three and six months ended June 30, 2022.

10.Net (loss) income per share

The Company adopted ASU 2020-06 on January 1, 2022, using the modified retrospective method, applicable to its convertible senior notes outstanding as of adoption. The Company has not changed any previously disclosed amounts or provided additional disclosures for comparative periods. ASU 2020-06 requires the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. Under the if-converted method, shares related to convertible senior notes, to the extent dilutive, are assumed to be converted into common stock at the beginning of the period.

Basic net income per share attributable to common stockholders is computed using the weighted average number of shares of common stock outstanding for the period, excluding dilutive securities, stock options, RSUs, and ESPP shares. Diluted net income per share attributable to common stockholders is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of dilutive securities, stock options, RSUs and ESPP shares under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net (loss) income per share amounts (in thousands, except per share data):

	Three Months Ended  June 30,						Six Months Ended June 30,
	2022			2021			2022			2021

11.Income taxes

The Company’s income tax expense and effective tax rate for the three and six months ended June 30, 2022 and 2021, were as follows (in thousands, except percentages):

	Three Months Ended  June 30,						Six Months Ended June 30,
	2022			2021			2022			2021

Effective tax rate		(13	%)		(11	%)		(88	%)		66	%

The tax rate is affected by the Company being a U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. The Company’s effective tax rate for the six months ended June 30, 2022 and 2021, also includes net discrete expense of $3.4 million and net discrete benefit of $2.4 million, respectively, primarily related to changes in tax laws, withholding taxes on royalties, changes in reserves, changes in accruals for unremitted earnings and other adjustments.

13.Commitments and contingencies

World Programming

The Company acquired World Programming Limited and a related company (collectively, “World Programming”) in December 2021. In 2010, SAS Institute, Inc. (“SAS”) filed an action against World Programing in the United States District Court for the Eastern District of North Carolina (the “NC Court”) alleging copyright infringement, breach of contract, fraudulent inducement to contract, and violations of the North Carolina Unfair and Deceptive Trade Practices Act (UDTPA). SAS was unsuccessful on its copyright claims but prevailed on its breach of contract, fraudulent inducement, and UDTPA claims and was awarded damages of $79.1 million in 2016 (the “NC Judgment”). The NC Court subsequently enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States until the NC Judgment was satisfied. At the time that the Company acquired World Programming, World Programming had partially paid the NC Judgment.

In relation to the NC Court order that enjoined World Programming from licensing its WPS Analytics Software to new customers for use in the United States, SAS filed a related matter in California, which resulted in the California court issuing an order that required certain then existing customers of World Programming to direct payment (of their licensing fees for WPS Analytics software) to SAS until the NC Judgment was satisfied.

On January 3, 2022, the Company paid the outstanding balance of $65.9 million on the NC Judgment. Despite payment in full, SAS has asserted that the Company has not satisfied the Judgment. The NC Court scheduled a hearing to address this issue for March 3, 2022 (the “March Hearing”). At the March Hearing, the NC Court confirmed that the Company’s January 3, 2022 payment fully satisfied the NC Judgment, and lifted the injunction that had enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States. On March 7, 2022, SAS agreed that the California court order was no longer necessary and together with World Programming, filed a joint notice of satisfaction of the NC Judgment with the

23

California court, thereby allowing customers of World Programming to resume payment of their licensing fees to World Programming directly.

In 2018, SAS filed litigation in the United States District Court for the Eastern District of Texas (the “Texas Court”) asserting that World Programming infringed SAS copyrights and patents. SAS voluntarily dismissed with prejudice its patent claims, and the Texas Court entered judgment in favor of World Programming on the copyright claims. SAS appealed the Texas Court judgment to the United States Court of Appeals for the Federal Circuit (the “Court of Appeals”). Oral arguments were held before the Court of Appeal on January 13, 2022. A decision from the Court of Appeals is pending.

Other legal proceedings

From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. The Company has received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend the Company, its partners, and its customers by determining the scope, enforceability, and validity of third-party proprietary rights, or to establish and enforce the Company’s proprietary rights.

Effects of proceedings

The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

14.Segment information

The Company defines its operating segments as components of its business where separate financial information is available and used by the chief operating decision maker (“CODM”) in deciding how to allocate resources to its segments and in assessing performance. The Company’s CODM is its Chief Executive Officer.

The Company has identified two reportable segments for financial reporting purposes: Software and Client Engineering Services. The primary measure of segment operating performance is Adjusted EBITDA, which is defined as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by management. Adjusted EBITDA includes an allocation of corporate headquarters costs.

Convertible Senior Notes

2027 Notes

In June 2022, we issued $230.0 million aggregate principal amount of 1.750% convertible senior notes due in 2027 (the "2027 Notes"), which includes the initial purchaser’s exercise in full of its option to purchase an additional $30.0 million principal amount of the 2027 Notes, in a private offering. The net proceeds from the issuance of the 2027 Notes was approximately $224.3 million after deducting discounts, commissions and estimated issuance costs.

We entered into an Indenture relating to the issuance of the 2027 Notes dated June 14, 2022 (the “Indenture”), by and between the Company and U.S. Bank Trust Company, National Association, as trustee. The Indenture includes customary covenants and sets forth certain events of default after which the 2027 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the 2027 Notes become automatically due and payable. The 2027 Notes are senior unsecured obligations of the Company.

27

The 2027 Notes mature on June 15, 2027, unless earlier repurchased, redeemed or converted. We may redeem for cash all or, subject to certain limitations, any portion of the 2027 Notes, at our option, on or after June 20, 2025 if the last reported sale price of our Class A Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. The 2027 Notes bear interest at a rate of 1.750% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2022.

The 2027 Notes have an initial conversion rate of 13.9505 shares of our Class A common stock per $1,000 principal amount of 2027 Notes, which is equivalent to an initial conversion price of approximately $71.68 per share of Class A common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events specified in the Indenture but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of a make whole fundamental change or a redemption period (each as defined in the Indenture), we will, in certain circumstances, increase the conversion rate by a specified number of additional shares for a holder who elects to convert its 2027 Notes in connection with such make whole fundamental change or during the relevant redemption period.

Holders of the 2027 Notes may convert all or any portion of their 2027 Notes at any time prior to the close of business on the business day immediately preceding December 15, 2026, in integral multiples of $1,000 principal amount, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on September 30, 2022, if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of the 2027 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Class A Common Stock and the conversion rate on each such trading day;

•if we call the 2027 Notes for redemption (which the Company may not do prior to June 20, 2025), at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date but only with respect to the 2027 Notes called (or deemed called) for redemption; or

•upon the occurrence of specified corporate events.

On or after December 15, 2026 until the close of business on the business day immediately preceding the maturity date, holders may convert their 2027 Notes at any time, regardless of the foregoing circumstances. Upon conversion, we will pay or deliver, as the case may be, cash, shares of Class A Common Stock or a combination of cash and shares of Class A Common Stock, at our election, in the manner and subject to the terms and conditions provided in the Indenture.

2024 Notes

In June 2022, using proceeds from the issuance of the 2027 Notes, we retired approximately $148.2 million principal amount of our convertible senior notes which mature in 2024 (the "2024 Notes" and together with the 2027 Notes, the “Convertible Notes”), by paying cash of approximately $192.4 million including accrued and unpaid interest.

Credit Agreement

In June 2022, we amended our $150.0 million credit facility to, among other things, permit the issuance of the 2027 Notes and extend the maturity date of the credit facility to December 15, 2025.

Impact of COVID-19

In March 2020, The World Health Organization declared the outbreak of COVID-19 a pandemic and a public health emergency of international concern. The global spread of COVID-19, including new and emerging variants, has created significant volatility and uncertainty since March 2020 and may continue into the future.

We are unable to accurately predict the full impact that COVID-19 will have due to numerous uncertainties, including the full scope of the disease, the duration of the outbreak, the number and intensity of subsequent waves of infections, actions that may be taken by governmental authorities, the impact to the businesses of our customers and partners, the development of treatments

28

and vaccines, and other factors identified in Part I, Item 1A – Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2021. We will continue to evaluate the nature and extent of the impact to our business, consolidated results of operations, and financial condition.

Factors Affecting our Performance

We believe that our future success will depend on many factors, including those described below. While these areas present significant opportunity, they also present risks that we must manage to achieve successful results. If we are unable to address these challenges, our business, operating results and prospects could be harmed. Please see “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021.

Seasonality and quarterly results

Our billings have historically been highest in the first and fourth quarters of any calendar year and may vary in future quarters. The timing of recording billings and the corresponding effect on our cash flows may vary due to the seasonality of the purchasing and payment patterns of our customers. In addition, the timing of the recognition of revenue, the amount and timing of operating expenses, including employee compensation, sales and marketing activities, and capital expenditures, may vary from quarter-to-quarter which may cause our reported results to fluctuate significantly. In addition, we may choose to grow our business for the long-term rather than to optimize for profitability or cash flows for a particular shorter-term period. This seasonality or the occurrence of any of the factors above may cause our results of operations to vary and our financial statements may not fully reflect the underlying performance of our business.

Integration of recent acquisitions

We believe that our recent acquisitions result in certain benefits, including expanding our portfolio of software and products and enabling us to better serve our customers’ requests for data analytics and simulation technology. However, to realize some of these anticipated benefits, the acquired businesses must be successfully integrated. The success of these acquisitions will depend in part on our ability to realize these anticipated benefits. We may fail to realize the anticipated benefits of these acquisitions for a variety of reasons.

Foreign currency fluctuations

Because of our substantial international operations, we are exposed to foreign currency risks that arise from our normal business operations, including in connection with our transactions that are denominated in foreign currencies, including the Euro, British Pound Sterling, Indian Rupee, Japanese Yen, and Chinese Yuan. To identify changes in our underlying business without regard to the impact of currency fluctuations, we evaluate certain of our operating results both on an as reported basis, as well as on a constant currency basis. For the remainder of our current fiscal year, we anticipate that our revenues and profit may be adversely impacted by changes in foreign currency rates.

Business Segments

We have identified two reportable segments: Software and Client Engineering Services:

•Software —Our Software segment includes software and software related services. The software component of this segment includes our portfolio of software products including our solvers and optimization technology products, high-performance computing software applications and hardware products, modeling and visualization tools, data analytics and analysis products, IoT platform and analytics tools, as well as support and the complementary software products we offer through our Altair Partner Alliance, or APA. The APA includes technologies ranging from computational fluid dynamics and fatigue, to manufacturing process simulation and cost estimation. The software related services component of this segment includes consulting, and training focused on product design and development expertise and analysis from the component level up to complete product engineering at any stage of the lifecycle.

•Client Engineering Services —Our client engineering services, or CES, segment provides client engineering services to support our customers with long-term, ongoing expertise. We operate our CES business by hiring engineers and data scientists for placement at a customer site for specific customer-directed assignments. We employ and pay them only for the duration of the placement.

29

Our other businesses which do not meet the criteria to be separate reportable segments are combined and reported as “Other” which represents innovative services and products, including toggled, our LED lighting business. toggled is focused on developing and selling next-generation solid state lighting technology along with communication and control protocols based on our intellectual property for the direct replacement of fluorescent light tubes with LED lamps. Other businesses combined within Other include potential services and product concepts that are still in development stages.

For additional information about our reportable segments and other businesses, see Note 14 in the Notes to consolidated financial statements in Item 1, Part I of this Quarterly Report on Form 10-Q.

Other operating income, net increased $5.2 million for the three months ended June 30, 2022 as compared to the three months ended June 30, 2021, primarily due to a $5.3 million gain recognized on the mark-to-market adjustment of contingent consideration associated with the World Programming acquisition.

Interest expense

	Three Months Ended  June 30,						Period-to-period change
(in thousands)	2022			2021			$			%
Interest expense	$	700		$	2,988		$	(2,288	)		(77	%)
As a percent of consolidated revenue		1	%		2	%

Interest expense decreased $2.3 million for the three months ended June 30, 2022, as compared to the three months ended June 30, 2021, primarily due to the adoption of ASU 2020-06 on January 1, 2022. As a result of this adoption, we account for the 2024 Notes as a single liability, which eliminates the amortization of the debt discount. Prior to January 1, 2022, the carrying amount of the equity component was recorded as a debt discount and amortized to interest expense. Interest expense related to the amortization of debt issuance costs was $0.4 million for the three months ended June 30, 2022, while interest expense related to the amortization of debt discount and issuance costs was $2.8 million for the three months ended June 30, 2021.

(in thousands)	2022		2021		$		%
Income tax expense	$	3,899	$	1,361	$	2,538		186	%

The effective tax rate was -13% and -11% for the three months ended June 30, 2022 and 2021, respectively. The tax rate is affected by our status as a U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which we operate, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. Our effective tax rate for the three months ended June 30, 2022 and 2021, also includes net discrete expense of $1.5 million and net discrete expense of $1.2 million, respectively, primarily related to changes in tax laws, withholding taxes on royalties, changes in reserves, changes in accruals for unremitted earnings and other adjustments.

Net loss

	Three Months Ended  June 30,						Period-to-period change

Gross profit increased by $26.6 million, or 13%, for the six months ended June 30, 2022, as compared to the six months ended June 30, 2021. This increase in gross profit was primarily attributable to the increase in software revenue and decrease in cost of revenue.

Operating expenses

Operating expenses, as discussed below, support all the products and services that we provide to our customers and, as a result, they are reported and discussed in the aggregate.

Stock-based compensation expense increased $9.0 million, employee compensation and related expense increased $5.3 million, primarily due to increased headcount, and cloud hosting and software maintenance expense increased $0.7 million in the current year. These increases were partially offset by a decrease in restructuring costs and consulting expense of $1.7 million and $1.2 million, respectively. The restructuring costs were non-recurring in the current period.

Interest expense decreased $4.7 million for the six months ended June 30, 2022, as compared to the six months ended June 30, 2021, primarily due to the adoption of ASU 2020-06 on January 1, 2022. As a result of this adoption, we account for the 2024 Notes as a single liability, which eliminates the amortization of the debt discount. Prior to January 1, 2022, the carrying amount of the equity component was recorded as a debt discount and amortized to interest expense. Interest expense related to the amortization of debt issuance costs was $0.8 million for the six months ended June 30, 2022, while interest expense related to the amortization of debt discount and issuance costs was $5.6 million for the six months ended June 30, 2021.

The effective tax rate was -88% and 66% for the six months ended June 30, 2022 and 2021 respectively. The tax rate is affected by our status as a U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which the we operate, the relative amount of income earned by jurisdiction and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. Our effective tax rate for the six months ended June 30, 2022 and 2021, also includes net discrete expense of $3.4 million and net discrete benefit of $2.4 million, respectively, primarily related to changes in tax laws, withholding taxes on royalties, changes in reserves, changes in accruals for unremitted earnings and other adjustments.

Net loss was $22.2 million for the six months ended June 30, 2022, as compared to net income of $0.7 million for the six months ended June 30, 2021. The net loss was primarily attributable to expense recognized on the repurchase of a portion of our 2024 Notes, increased stock-based compensation expense and increased foreign currency losses in the current year period, partially offset by an increase in revenue and a gain on the mark-to-market adjustment of contingent consideration, as described above.

Non-GAAP financial measures

We monitor the following key non-GAAP (United States generally accepted accounting principles) financial and operating metrics to help us evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions. In analyzing and planning for our business, we supplement our use of GAAP financial measures with non-GAAP financial measures, including Billings as a liquidity measure, Adjusted EBITDA as a performance measure and Free Cash Flow as a liquidity measure.

Adjusted EBITDA	$	16,440	$	9,496	$	63,030	$	46,456
Free Cash Flow					$	14,584	$	49,331

Billings. Billings consists of our total revenue plus the change in our deferred revenue, excluding deferred revenue from acquisitions during the period. Given that we generally bill our customers at the time of sale, but typically recognize a portion of the related revenue ratably over time, management believes that Billings is a meaningful way to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers.

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by management. Our management team believes that Adjusted EBITDA is a meaningful measure of performance as it is commonly utilized by management and the investment community to analyze operating performance in our industry.

Free Cash Flow. Free Cash Flow is a non-GAAP measure that we calculate as cash flow provided by operating activities less capital expenditures. Management believes that Free Cash Flow is useful in analyzing our ability to service and repay debt, when applicable, and return value directly to stockholders.

These non-GAAP financial measures reflect an additional way of viewing aspects of our business that, when viewed with our GAAP results and the accompanying reconciliations to corresponding GAAP financial measures included in the tables below, may provide a more complete understanding of factors and trends affecting our business. These non-GAAP financial measures should not be relied upon to the exclusion of GAAP financial measures and are by definition an incomplete understanding of the Company and must be considered in conjunction with GAAP measures.

40

We believe that the non-GAAP measures disclosed herein are only useful as an additional tool to help management and investors make informed decisions about our financial and operating performance and liquidity. By definition, non-GAAP measures do not give a full understanding of the Company. To be truly valuable, they must be used in conjunction with the comparable GAAP measures. In addition, non-GAAP financial measures are not standardized. It may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. We strongly encourage investors to review our consolidated financial statements and the notes thereto in their entirety and not to rely on any single financial measure.

Reconciliation of non-GAAP financial measures

The following tables provides reconciliations of revenue to Billings, net income (loss) to Adjusted EBITDA, and net cash provided by operating activities to Free Cash Flow:

Recurring software license rate

A key factor to our success is our recurring software license rate which we measure through Billings, primarily derived from annual renewals of our existing subscription customer agreements. Recurring revenue streams allow us to create more consistent, predictable cash flows and drive greater long-term customer value. We believe the recurring software license rate is a key factor to our success and we monitor this measure to ensure our go-to-market strategy is driving long-term success of our business.

41

We calculate our recurring software license rate for a particular period by dividing (i) the sum of software term-based license Billings, software license maintenance Billings, and 20% of software perpetual license Billings which we believe approximates maintenance as an element of the arrangement by (ii) the total software license Billings including all term-based subscriptions, maintenance, and perpetual license billings from all customers for that period. For the six months ended June 30, 2022 and 2021, our recurring software license rate was 93% and 92%, respectively. The recurring software license rate may vary from period to period.

Liquidity and capital resources

As of June 30, 2022, our principal sources of liquidity were $416.1 million in cash and cash equivalents and $150.0 million availability on our credit facility. We have outstanding debt in the form of our Convertible Notes with a $311.8 million principal amount as of June 30, 2022.

During the period ended June 30, 2022, the conditions allowing holders of the Convertible Notes to convert were not met. Therefore, the Convertible Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2022. We have the ability to settle the Convertible Notes in cash, shares of our common stock, or a combination of cash and shares of our common stock at our own election.

During the period ended June 30, 2022, under our stock repurchase program, we repurchased 85,119 shares of our Class A Common Stock at an average price of $51.52 per share for a total cost of approximately $4.4 million. As of June 30, 2022, approximately $45.6 million of shares remained available for repurchase under the program.

We continue to evaluate possible acquisitions and other strategic transactions designed to expand our business. As a result, our expected uses of cash could change, our cash position could be reduced, or we may incur additional debt obligations to the extent we complete additional acquisitions.

Our existing cash and cash equivalents may fluctuate during fiscal 2022, due to changes in our planned cash expenditures, including changes in incremental costs such as direct costs and integration costs related to acquisitions. Cash from operations could also be affected by various risks and uncertainties, including, but not limited to, the effects of COVID-19 and global unrest. It is possible that certain customers may unilaterally decide to extend payments on accounts receivable, however our customer base is comprised primarily of larger organizations with typically strong liquidity and capital resources.

We believe that our existing cash balances, together with funds generated from operations and amounts available under our credit facility, will be sufficient to finance our operations and meet our foreseeable cash requirements for the next twelve months. We also believe that our financial resources, along with managing discretionary expenses, will allow us to manage the impact of COVID-19 on our business operations for the foreseeable future and withstand global unrest, which could include reductions in revenue and delays in payments from customers and partners. We will continue to evaluate our financial position as developments evolve relating to COVID-19 and global unrest.

Revolving credit facility

We have a $150.0 million credit facility with a maturity date of December 15, 2025 (“2019 Amended Credit Agreement”). The 2019 Amended Credit Agreement allows us to request that the aggregate commitments under the 2019 Amended Credit Agreement be increased by up to $50.0 million for a total of $200.0 million, subject to certain conditions. In June 2022, we amended our 2019 Amended Credit Agreement to, among other things, permit the issuance of the 2027 Notes and extend the maturity date of the credit facility to December 2025.

As of June 30, 2022, there were no outstanding borrowings under the 2019 Amended Credit Agreement and there was $150.0 million available for future borrowing. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures and permitted acquisitions. As of June 30, 2022, we were in compliance with the financial covenants.

For additional information about the 2019 Amended Credit Agreement, refer to our consolidated financial statements for the year ended December 31, 2021, included in our Annual Report on Form 10-K filed with the SEC on February 28, 2022.

Cash flows

As of June 30, 2022, we had cash and cash equivalents of $416.1 million available for working capital purposes, acquisitions, and capital expenditures; $329.2 million of this amount was held in the United States and $81.1 million was held in the APAC and EMEA regions with the remainder held in Canada, Mexico, and South America.

Other than statutory limitations, there are no significant restrictions on the ability of our subsidiaries to pay dividends or make other distributions to Altair. Based on our current liquidity needs and repatriation strategies, we expect that we can manage our global liquidity needs without material adverse tax implications.

The following table summarizes our cash flows for the periods indicated:

	Six Months Ended June 30,
(in thousands)	2022			2021
Net cash provided by operating activities	$	18,041		$	54,722
Net cash used in investing activities		(41,439	)		(5,780	)

Effect of exchange rate changes on cash, cash equivalents and restricted cash		(6,226	)		(847	)
Net increase in cash, cash equivalents and restricted cash	$	2,294		$	18,774

Net cash provided by operating activities

Net cash provided by operating activities for the six months ended June 30, 2022, was $18.0 million, which reflects a decrease of $36.7 million compared to the six months ended June 30, 2021. This decrease was the result of a $65.9 million payment in January on an existing legal judgment against World Programming, and changes to our working capital position for the six months ended June 30, 2022, as compared to the six months ended June 30, 2021.

Net cash used in investing activities

Net cash used in investing activities for the six months ended June 30, 2022, was $41.4 million, which reflects an increase of $35.7 million compared to the six months ended June 30, 2021. The increase was primarily the result of $37.7 million in cash payments for business acquisitions in the current year.

Net cash provided by (used in) financing activities

Net cash provided by financing activities for the six months ended June 30, 2022, was $31.9 million, which reflects an increase in cash provided of $61.2 million for the six months ended June 30, 2021. For the six months ended June 30, 2022, we received aggregate proceeds of $224.3 million from the issuance of our 2027 Notes, net of certain discounts and commissions, partially offset by $192.8 million proceeds used for the repurchase of a portion of our 2024 Notes. For the six months ended June 30, 2021, we made a payment on our revolving credit facility of $30.0 million.

Effect of exchange rate changes on cash, cash equivalents and restricted cash

There were adverse effects of exchange rate changes on cash, cash equivalents and restricted cash of $6.2 million and $0.8 million, respectively, for the six months ended June 30, 2022, and June 30, 2021.

43

Commitments

As of June 30, 2022, our principal commitments consist of our $81.8 million and $230.0 million convertible notes due in 2024 and 2027, respectively.

As of December 31, 2021, there was a balance payable on an existing legal judgment against World Programming. We paid this judgment in January 2022, for $65.9 million.

There were no other material changes in our commitments as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.

Recently issued accounting pronouncements

Effective January 1, 2022, we adopted Accounting Standards Update, or ASU, 2020-06 using the modified retrospective approach. As a result, our 2024 Notes are accounted for as a single liability measured at amortized cost, as no other embedded features require bifurcation and recognition as derivatives. Adoption of the new standard resulted in a decrease to Accumulated deficit of $23.9 million, a decrease to Additional paid-in capital of $50.0 million, and an increase to Convertible senior notes, net of $26.1 million.

See Note 2 in the Notes to consolidated financial statements in Item 1, Part I of this Quarterly Report on Form 10-Q for a full description of the recent accounting pronouncements and our expectation of their impact, if any, on our results of operations and financial condition.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain global market risks, including foreign currency exchange risk and interest rate risk associated with our revolving credit facility.

Foreign Currency Risk

As a result of our substantial international operations, we are exposed to foreign currency risks that arise from our normal business operations, including in connection with our transactions that are denominated in foreign currencies. In addition, we translate sales and financial results denominated in foreign currencies into United States dollars for purposes of our consolidated financial statements. As a result, appreciation of the United States dollar against these foreign currencies generally will have a negative impact on our reported revenue and operating income while depreciation of the United States dollar against these foreign currencies will generally have a positive effect on reported revenue and operating income.

As of June 30, 2022, we do not have any foreign currency hedging contracts. Based on our current international operations, we do not plan on engaging in hedging activities in the near future.

Market Risk and Market Interest Risk

In June 2022, we issued $230.0 million aggregate principal amount of 1.750% convertible senior notes due in 2027. In June 2019, we issued $230.0 million aggregate principal amount of 0.250% convertible senior notes due 2024 of which $148.2 million aggregate principal amount had been repurchased as of June 30, 2022. The 2027 Notes and 2024 Notes have fixed annual interest rates at 1.750% and 0.250%, respectively, and, therefore, we do not have economic interest rate exposure on our Convertible Notes. However, the value of the Convertible Notes is exposed to interest rate risk. Generally, the fair market value of our fixed interest rate Convertible Notes will increase as interest rates fall and decrease as interest rates rise. In addition, the fair values of the Convertible Notes are affected by our stock price. The fair value of the Convertible Notes will generally increase as our Class A common stock price increases in value and will generally decrease as our Class A common stock price declines in value. We carry the Convertible Notes at face value less unamortized issuance costs on our balance sheet, and we present the fair value for required disclosure purposes only.

As of June 30, 2022, we had cash, cash equivalents and restricted cash of $416.3 million, consisting primarily of bank deposits and money market funds. As of June 30, 2022, we had no outstanding borrowings under our 2019 Amended Credit Agreement. Such interest-bearing instruments carry a degree of interest rate risk; however, historical fluctuations of interest expense have not been significant.

44

Interest rate risk relates to the gain/increase or loss/decrease we could incur on our debt balances and interest expense associated with changes in interest rates. Changes in interest rates would impact the amount of interest income we realize on our invested cash balances. It is our policy not to enter into derivative instruments for speculative purposes, and therefore, we hold no derivative instruments for trading purposes.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Exchange Act) that are designed to ensure that information required to be disclosed in periodic reports filed with the SEC under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13(a)-15(e) under the Exchange Act as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2022.

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) that occurred during the quarter ended June 30, 2022, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

World Programming

We acquired World Programming Limited and a related company (collectively, “World Programming”) in December 2021. In 2010, SAS Institute, Inc. (“SAS”) filed an action against World Programing in the United States District Court for the Eastern District of North Carolina (the “NC Court”) alleging copyright infringement, breach of contract, fraudulent inducement to contract, and violations of the North Carolina Unfair and Deceptive Trade Practices Act (UDTPA). SAS was unsuccessful on its copyright claims but prevailed on its breach of contract, fraudulent inducement, and UDTPA claims and was awarded damages of $79.1 million in 2016 (the “NC Judgment”). The NC Court subsequently enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States until the NC Judgment was satisfied. At the time that we acquired World Programming, World Programming had partially paid the NC Judgment.

In relation to the NC Court order that enjoined World Programming from licensing its WPS Analytics Software to new customers for use in the United States, SAS filed a related matter in California, which resulted in the California court issuing an order that required certain then existing customers of World Programming to direct payment (of their licensing fees for WPS Analytics software) to SAS until the NC Judgment was satisfied.

On January 3, 2022, we paid the outstanding balance of $65.9 million on the NC Judgment. Despite payment in full, SAS continued to assert that we had not fully satisfied the NC Judgment. The NC Court scheduled a hearing to address this issue for March 3, 2022 (the “March Hearing”). At the March Hearing, the NC Court confirmed that our January 3, 2022 payment fully satisfied the NC Judgment, and lifted the injunction that had enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States. On March 7, 2022, SAS agreed that the California court order was no longer necessary and together with World Programming, filed a joint notice of satisfaction of the NC Judgment with the California court, thereby allowing customers of World Programming to resume payment of their licensing fees to World Programming directly.

In 2018, SAS filed litigation in the United States District Court for the Eastern District of Texas (the “Texas Court”) asserting that World Programming infringed SAS copyrights and patents. SAS voluntarily dismissed with prejudice its patent claims, and the Texas Court entered judgment in favor of World Programming on the copyright claims. SAS appealed the Texas Court judgment to the United States Court of Appeals for the Federal Circuit (the “Court of Appeals”). Oral arguments were held before the Court of Appeal on January 13, 2022. A decision from the Court of Appeals is pending.

Other legal proceedings

From time to time, we may be subject to other legal proceedings and claims in the ordinary course of business. We have received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend ourselves, our partners and our customers by determining the scope, enforceability and validity of third-party proprietary rights, or to establish and enforce our proprietary rights. The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors

The risk factors set forth below supplement the risk factors previously disclosed in Part 1, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021. The following risk factors should be read in conjunction with the risk factors regarding the 2024 Notes set forth in our Annual Report on 10-K for the year ended December 31, 2021.

The 2027 Notes will be effectively subordinated to our secured debt (including borrowings under our revolving credit facility) and any liabilities of our subsidiaries.

The 2027 Notes will rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the 2027 Notes; equal in right of payment to any of our liabilities that are not so subordinated, such as our existing 2024 Notes; effectively junior in right of payment to any of our secured indebtedness (including all amounts outstanding under our revolving credit facility) to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure debt ranking senior or equal in right of payment to the 2027 Notes (including all amounts outstanding under our revolving credit facility) will be available to pay obligations on the 2027 Notes

46

only after the secured debt has been repaid in full from these assets, and the assets of our subsidiaries will be available to pay obligations on the 2027 Notes only after all indebtedness and other liabilities (including trade payables) of our subsidiaries have been repaid in full. There may not be sufficient assets remaining to pay amounts due on any or all of the 2027 Notes then outstanding. The indenture governing the 2027 Notes will not prohibit us from incurring additional senior debt or secured debt, nor will it prohibit any of our subsidiaries from incurring indebtedness or additional liabilities.

The 2027 Notes are our obligations only and a substantial portion of our operations are conducted through, and a substantial portion of our consolidated assets are held by, our subsidiaries.

The 2027 Notes are our obligations exclusively and are not guaranteed by any of our operating subsidiaries. A substantial portion of our operations is conducted through, and a substantial portion of our consolidated assets is held by, our subsidiaries. Accordingly, our ability to service our debt, including the 2027 Notes, depends in part on the results of operations of our subsidiaries and upon the ability of such subsidiaries to provide us with cash, whether in the form of dividends, loans or otherwise, to pay amounts due on our obligations, including the 2027 Notes. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make payments on the 2027 Notes or to make any funds available for that purpose. In addition, dividends, loans or other distributions to us from such subsidiaries may be subject to contractual and other restrictions and are subject to other business considerations.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the amounts payable under our revolving credit facility, the 2027 Notes and the 2024 Notes, or to make cash payments in connection with any conversion of 2027 Notes or the 2024 Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional debt financing or equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In addition, the credit agreement governing our revolving credit facility contains, and any of our future debt agreements may contain, restrictive covenants that may prohibit us from adopting any of these alternatives. Our failure to comply with these covenants could result in an event of default which, if not cured or waived, could result in the acceleration of our debt.

We may still incur substantially more debt or take other actions which would intensify the risks discussed above.

We and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our then-existing debt instruments, some of which may be secured debt, and other agreements. We are not restricted under the terms of the indenture governing the 2027 Notes, or the indenture governing the 2024 Notes, from incurring additional debt, securing existing or future debt, recapitalizing our debt or taking a number of other actions that are not limited by the terms of the indenture governing the 2027 Notes or the indenture governing the 2024 Notes that could have the effect of diminishing our ability to make payments on the 2027 Notes when due. Our existing revolving credit facility restricts our ability to incur additional indebtedness, including secured indebtedness, but if those restrictions are waived, or the facility matures or is repaid, we may not be subject to such restrictions under the terms of any subsequently incurred indebtedness.

We may not have the ability to raise the funds necessary to settle for cash conversions of the 2027 Notes or to repurchase for cash the 2027 Notes upon a fundamental change, and our current debt contains, and our future debt may contain, limitations on our ability to pay cash upon conversion or repurchase of the 2027 Notes.

Holders of the 2027 Notes will have the right to require us to repurchase their 2027 Notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the 2027 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, upon conversion of the 2027 Notes, unless we elect to deliver solely shares of our Class A common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the 2027 Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of 2027 Notes surrendered therefore or 2027 Notes being converted.

In addition, our ability to repurchase the 2027 Notes or to pay cash upon conversions of the 2027 Notes may be limited by law, by regulatory authority or by agreements governing our indebtedness including our existing revolving credit facility. Our 2024

47

Notes contain substantially identical conversion and repurchase features. Our failure to repurchase the 2027 Notes or the 2024 Notes at a time when the repurchase is required by the indenture governing the 2027 Notes or the indenture governing the 2024 Notes or to pay any cash payable on future conversions of the 2024 Notes or the 2027 Notes as required by the indentures governing the 2024 Notes or the 2027 Notes would constitute a default under the applicable indenture. A default under the indenture governing the 2027 Notes or the indenture governing the 2024 Notes or the occurrence of a fundamental change itself would likely also lead to a default under our revolving credit facility, and may lead to a default under agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the 2027 Notes or make cash payments upon conversions thereof.

Our revolving credit facility limits our ability to pay any cash amount upon the conversion or repurchase of the 2027 Notes.

Our existing revolving credit facility prohibits us from making any cash payments on the conversion or repurchase of the 2027 Notes if a default under such credit facility exists or would be created thereby. In addition, our ability to make cash payments on the conversion or repurchase of the 2027 Notes will be limited to the extent we do not satisfy certain financial covenant tests after giving effect to such payments. Any new credit facility that we may enter into may have similar restrictions. Our failure to make cash payments upon the conversion or repurchase of the 2027 Notes as required under the terms of the 2027 Notes would permit holders of the 2027 Notes to accelerate our obligations under the 2027 Notes.

The conditional conversion feature of the 2027 Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the 2027 Notes is triggered, holders of 2027 Notes will be entitled to convert the 2027 Notes at any time during specified periods at their option. If one or more holders elect to convert their 2027 Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our Class A common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity.

Our 2024 Notes contain substantially identical conversion features. Neither the 2024 Notes nor the 2027 Notes are convertible under this feature during the quarter ending September 30, 2022. Whether the 2024 Notes or the 2027 Notes will be convertible following this fiscal quarter will depend on the satisfaction of this condition or another conversion condition in the future. As of June 30, 2022, our 2024 Notes and 2027 Notes are classified as long-term liabilities. In addition, even if holders do not elect to convert their 2027 Notes or the 2024 Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2027 Notes or the 2024 Notes, as applicable, as a current rather than a long-term liability, which would result in a material reduction of our net working capital.

Provisions in the indenture for the 2027 Notes may deter or prevent a business combination that may be favorable to you.

If a fundamental change occurs prior to the maturity date, holders of the 2027 Notes will have the right, at their option, to require us to repurchase all or a portion of their 2027 Notes. In addition, if a make-whole fundamental change occurs prior to the maturity date, we will in some cases be required to increase the conversion rate for a holder that elects to convert its 2027 Notes in connection with such make-whole fundamental change. Furthermore, the indenture for the 2027 Notes will prohibit us from engaging in certain mergers or acquisitions unless, among other things, the surviving entity assumes our obligations under the 2027 Notes. These and other provisions in the indenture for the 2027 Notes could deter or prevent a third party from acquiring us even when the acquisition may be favorable to you. Comparable provisions exist in the indenture for the 2024 Notes.

Conversion of the 2027 Notes will dilute the ownership interest of existing stockholders, including holders who had previously converted their 2027 Notes, and may otherwise depress the price of our Class A common stock.

The conversion of some or all of the 2027 Notes will dilute the ownership interests of existing stockholders to the extent we deliver shares of our Class A common stock upon conversion of any of the 2027 Notes. The 2027 Notes may from time to time in the future be convertible at the option of their holders prior to their scheduled terms under certain circumstances. Any sales in the public market of the Class A common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the 2027 Notes may encourage short selling by market participants because the conversion of the 2027 Notes could be used to satisfy short positions, and the anticipated conversion of the 2027 Notes into shares of our common stock could depress the price of our common stock.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Concept Engineering

On June 9, 2022, in connection with our acquisition of Concept Engineering (“Concept”), we agreed to issue to the stockholders of Concept an aggregate of 112,296 shares of the Company’s Class A Common Stock, par value $0.0001 per share, with 56,148 shares issuable on each of June 9, 2023 and June 9, 2024, subject to potential reduction in certain circumstances. All shares are subject to customary securities law restrictions on transferability. All shares were issued without registration under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) of the Securities Act. Concept’s existing stockholders provided customary representations for a private placement of securities and agreed to customary restrictions on transferability.

Repurchase of 2024 Notes

On June 14, 2022, in connection with our issuance of our 2027 Notes, we entered into separate privately negotiated agreements with certain holders of our 2024 Notes to repurchase an aggregate of $148.2 million aggregate principal amount of the 2024 Notes for approximately $192.8 million in cash.

Purchases of Equity Securities by the Issuer

In February 2022, our Board of Directors approved a stock repurchase program to repurchase up to $50.0 million of our Class A Common Stock. Purchases under the stock repurchase program may be made from time to time in the open market at prevailing prices, or through privately negotiated transactions. We are not obligated to repurchase any dollar amount or number of shares, and the stock repurchase program may be suspended or terminated at any time. All shares repurchased under the stock repurchase program are retired.

The following table presents information regarding our purchases of Class A Common Stock during the quarter ended June 30, 2022:

	Total Number of Shares Purchased (1)		Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs		Approximate dollar value of Shares that may yet be Purchased under the Plans or Programs
April 1, 2022 through April 30, 2022		—	$	—		—	$	50,000,000
May 1, 2022 through May 31, 2022		85,119	$	51.52		85,119	$	45,612,733
June 1, 2022 through June 30, 2022		—	$	—		—	$	45,612,733
Total		85,119	$	51.52		85,119	$	45,612,733

(1)All shares were repurchased in open market transactions pursuant to the $50.0 million share repurchase program authorized by our Board of Directors and publicly announced on February 24, 2022. Shares repurchased under this program may be repurchased in open market transactions, by block purchase, in privately negotiated transactions or otherwise.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Description of Business

1.Organization and description of business

Altair Engineering Inc. (“Altair” or the “Company”) is incorporated in the state of Delaware. The Company is a global leader in computational science and artificial intelligence (”AI”) that provides software and cloud solutions in simulation, high-performance computing (“HPC”), data analytics, and AI. Altair enables organizations across all industries to compete more effectively and drive smarter decisions in an increasingly connected world - all while creating a greener, more sustainable future. The Company is headquartered in Troy, Michigan.

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2021, included in the most recent Annual Report on Form 10-K filed with the SEC.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.

Significant accounting policies

There have been no material changes to our significant accounting policies as of and for the six months ended June 30, 2022, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2021.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Guidance

2.Recent accounting guidance

Accounting standards adopted

Debt – In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020-06, a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The Company adopted ASU 2020-06 effective as of January 1, 2022, using the modified retrospective approach. Adoption of the new standard resulted in a decrease to accumulated deficit of $23.9 million, a decrease to additional paid-in capital of $50.0 million, and an increase to convertible senior notes, net of $26.1 million. Interest expense recognized in the current and future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost.

Accounting standards not yet adopted

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. This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are optional and effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Government Assistance – In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This ASU requires certain disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The amendment requires disclosure of information about the nature of the transactions and the related accounting policy used to account for the transactions, information regarding the line items within the consolidated financial statements that are affected by the transactions, and significant terms and conditions of the transactions. ASU 2021-10 is effective for annual periods beginning after December 15, 2021, with early application permitted. The Company is currently evaluating the effect the adoption of this new guidance will have on its consolidated financial statement disclosures.

Stock repurchase program

In February 2022, the Company’s Board of Directors approved a stock repurchase program to repurchase up to $50.0 million of the Company’s Class A Common Stock. Purchases under the stock repurchase program may be made from time to time in the open market at prevailing prices, or through privately negotiated transactions. The Company is not obligated to repurchase any dollar amount or number of shares, and the stock repurchase program may be suspended or terminated at any time. All shares repurchased under the stock repurchase program are retired.

During the period ended June 30, 2022, under our stock repurchase program, we repurchased 85,119 shares at an average price of $51.52 per share for a total cost of $4.4 million. As of June 30, 2022, $45.6 million of shares of Class A Common Stock remained available for repurchase under the program.

Mezzanine equity

In 2017, the Company issued 200,000 shares of Class A Common Stock to a third-party as partial consideration for the purchase of developed technology. These shares had a put right that could be exercised by the holder five years from date of purchase at $12.50 per share that required the shares to be recorded at issuance date fair value and classified as mezzanine equity in the consolidated balance sheet.

During the year ended December 31, 2020, the third-party holder sold 133,336 shares on the open market and as a result, the issuance date fair value of those shares was reclassified into permanent equity from mezzanine equity. As of June 30, 2022, the put right has lapsed and the issuance date fair value of the remaining 66,664 shares were reclassified into permanent equity from mezzanine equity.

Restructuring expense

In 2021, the Company initiated a restructuring plan to realign resources with the Company’s business outlook and cost structure. The restructuring plan resulted in charges for employee termination benefits of $1.7 million and $5.1 million for the three and six months ended June 30, 2021, respectively. There were no restructuring costs for the three and six months ended June 30, 2022. The restructuring costs were attributable primarily to the Software reportable segment. The restructuring plan was completed, and all amounts were paid in 2021.

2022 Acquisitions

Concept Engineering

In June 2022, the Company entered into a stock purchase agreement and simultaneously acquired 100% of the outstanding capital stock of Concept Engineering, a leading provider of electronic system visualization software that accelerates the development, manufacture, and service of complex electrical and electronic systems, for preliminary aggregate consideration of $25.7 million. See Note 9 for further information on this acquisition. Concept Engineering’s software will be integrated into Altair’s Electronic System Design suite and will be available via Altair Units.

The acquisition of Concept Engineering will be accounted for as a business combination under the acquisition method of accounting. As of June 30, 2022, the book value of assets acquired and liabilities assumed were reported in the Company’s consolidated balance sheet. The remaining purchase price of $22.7 million has been recorded in goodwill pending fair value allocation. All goodwill is recorded in the Software segment.

The primary areas that remain preliminary relate to the fair value of intangible assets acquired, certain tangible assets and liabilities acquired, income taxes and residual goodwill. The Company expects to finalize the valuation as soon as practicable, but not later than one year from the acquisition date.

Other business acquisitions

During the six months ended June 30, 2022, the Company completed three other business acquisitions that will be accounted for as business combinations under the acquisition method for preliminary transaction consideration of $18.0 million. As of June 30, 2022, $7.8 million of preliminary consideration for two of these acquisitions was reported in goodwill in the consolidated balance sheet pending fair value allocation. All goodwill is recorded in the Software segment. The Company expects to finalize the valuations as soon as practicable, but not later than one year from the acquisition dates. These acquisitions were not material to the Company’s consolidated financial statements.

The operating results of each acquisition have been included in the consolidated financial statements since the respective dates of acquisition. The Company’s transaction costs related to its 2022 acquisitions were not material.

2021 Acquisitions

World Programming

In December 2021, the Company acquired all of the outstanding capital stock of two related privately held companies, World Programming Limited and December 2015 Software Limited (together “World Programming”), from the stockholders named therein, for preliminary aggregate consideration of $73.0 million. The preliminary consideration consisted of cash in the amount of $50.0 million, subject to a customary working capital adjustment, and contingent consideration of $23.0 million, including $19.5 million of the Company’s Class A Common Stock (the “Contingent Stock Consideration”) and a measurement period adjustment of $3.5 million recognized in 2022. The dates on which the Contingent Stock Consideration is issuable and the number of shares issuable on such dates depend primarily on certain aspects of legal proceedings in which World Programming and SAS Institute, Inc. are engaged. For further information on the legal proceedings see Note 13.

The Company is required to mark-to-market the Contingent Stock Consideration liability based on the trading price of the Company’s Class A Common Stock. For the three and six months ended June 30, 2022, the Company recognized a gain of $5.3 million on the mark-to-market adjustment of contingent consideration which is included in Other operating income, net in the consolidated statements of operations.

In addition, per the stock purchase agreement, $29.5 million of Class A Common Stock will be issued subject to the continuing employment of certain key employees and are not reflected in aggregate consideration but will be recognized as stock-based compensation over the service period of three years.

As of June 30, 2022, Other accrued expenses and current liabilities included $0.4 million of contingent consideration due to employees.

The acquisition has been accounted for as a business combination under the acquisition method of accounting, which results in acquired assets and assumed liabilities being measured at their estimated fair value as of the acquisition date. The following table summarizes the preliminary purchase consideration transferred to acquire World Programming and the amounts of identified assets acquired and liabilities assumed at the acquisition date (in thousands):

Fair value of consideration transferred	$	73,043
Recognized amounts of identifiable assets acquired and liabilities assumed:
Cash		1,895

Deferred tax liabilities and other tax reserves		(11,406	)
Total net identifiable assets acquired and liabilities assumed		(27,995	)
Goodwill (1)	$	101,038

(1)Goodwill is primarily attributable to market synergies expected to arise after the acquisition and is not deductible for tax purposes. All goodwill is recorded in the Software segment.

The preliminary estimated fair values of assets acquired and liabilities assumed, and identifiable intangible assets may be subject to change as additional information is received. The valuation was complex due to the significant estimation uncertainty in certain assumptions used to determine the fair value of intangible assets acquired and contingent consideration. The Company continues to collect information with regard to its estimates and assumptions, including the fair value of intangible assets acquired, certain tangible assets and liabilities acquired, contingent consideration, income taxes and residual goodwill. The Company expects to finalize the valuation as soon as practicable, but not later than one year from the acquisition date.

Convertible senior notes

2027 Notes

In June 2022, the Company issued $230.0 million aggregate principal amount of 1.750% convertible senior notes due in 2027 (the "2027 Notes"), which includes the initial purchaser’s exercise in full of its option to purchase an additional $30.0 million principal amount of the 2027 Notes, in a private offering. The net proceeds from the issuance of the 2027 Notes was $224.3 million after deducting discounts, commissions and estimated issuance costs.

The Company entered into an Indenture relating to the issuance of the 2027 Notes dated June 14, 2022 (the “Indenture”), by and between the Company and U.S. Bank Trust Company, National Association, as trustee. The Indenture includes customary covenants and sets forth certain events of default after which the 2027 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the 2027 Notes become automatically due and payable. The 2027 Notes are senior unsecured obligations of the Company.

The 2027 Notes mature on June 15, 2027, unless earlier repurchased, redeemed or converted. The Company may redeem for cash all or, subject to certain limitations, any portion of the 2027 Notes, at its option, on or after June 20, 2025 if the last reported sale price of Altair's Class A Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. The 2027 Notes bear interest at a rate of 1.750% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2022.

The 2027 Notes have an initial conversion rate of 13.9505 shares of the Company's Class A common stock per $1,000 principal amount of 2027 Notes, which is equivalent to an initial conversion price of approximately $71.68 per share of Class A common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events specified in the Indenture but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of a make whole fundamental change or a redemption period (each as defined in the Indenture), the Company will, in certain circumstances, increase the conversion rate by a specified number of additional shares for a holder who elects to convert its 2027 Notes in connection with such make whole fundamental change or during the relevant redemption period.

Holders of the 2027 Notes may convert all or any portion of their 2027 Notes at any time prior to the close of business on the business day immediately preceding December 15, 2026, in integral multiples of $1,000 principal amount, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on September 30, 2022, if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of the 2027 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Class A Common Stock and the conversion rate on each such trading day;

•if the Company calls the 2027 Notes for redemption (which the Company may not do prior to June 20, 2025), at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date but only with respect to the 2027 Notes called (or deemed called) for redemption; or

•upon the occurrence of specified corporate events.

On or after December 15, 2026 until the close of business on the business day immediately preceding the maturity date, holders may convert their 2027 Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of Class A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture.

During the period ended June 30, 2022, the conditions allowing holders of the 2027 Notes to convert were not met. Therefore, the 2027 Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2022.

2024 Notes

In June 2019, the Company issued $230.0 million aggregate principal amount of 0.25% convertible senior notes due in 2024 (the "2024 Notes" and together with the 2027 Notes, the “Convertible Notes”), which includes the underwriters’ exercise in full of their option to purchase an additional $30.0 million principal amount of the 2024 Notes, in a public offering. The net proceeds from the issuance of the 2024 Notes were $221.9 million after deducting the underwriting discounts and commissions and estimated issuance costs. The 2024 Notes bear interest at a rate of 0.25% per year, payable semi-annually in arrears on June 1 and December 1 of each year, commencing December 1, 2019. The 2024 Notes mature on June 1, 2024, unless, earlier repurchased or redeemed by the Company or converted pursuant to their terms. The 2024 Notes have an initial conversion rate of 21.5049 shares of the Company's Class A common stock per $1,000 principal amount of 2024 Notes, which is equivalent to an initial conversion price of approximately $46.50 per share of its Class A common stock. Refer to the Company’s consolidated financial statements for the year ended December 31, 2021, for details of the issuance of the 2024 Notes.

Prior to January 1, 2022, the Company separated the 2024 Notes into liability and equity components. On issuance, the carrying amount of the equity component was recorded as a debt discount and subsequently amortized to interest expense. Effective January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective approach. As a result, the 2024 Notes are accounted for as a single liability measured at amortized cost, as no other embedded features require bifurcation and recognition as derivatives. Adoption of the new standard resulted in a decrease to Accumulated deficit of $23.9 million, a decrease to Additional paid-in capital of $50.0 million, and an increase to Convertible senior notes, net of $26.1 million.

During the three months ended June 30, 2022, using proceeds from the issuance of the 2027 Notes, the Company entered into separate privately negotiated transactions with certain holders of the 2024 notes to repurchase and retire $148.2 million aggregate principal amount of the 2024 notes for an aggregate amount of $192.4 million of cash including accrued and unpaid interest. The Company recognized expense of $16.6 million, representing the fair value of the consideration paid to certain holders of the 2024 Notes in excess of the value to which they were entitled to receive on the respective settlement dates. The amount is included in Other expense, net in the Company’s consolidated statement of operations.

As of June 30, 2022, $81.8 million principal amount of the 2024 Notes remained outstanding. The Company may settle the 2024 Notes in cash, shares of Class A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election.

During the period ended June 30, 2022, the conditions allowing holders of the 2024 Notes to convert were not met. Therefore, the 2024 Notes were classified as long-term debt on the consolidated balance sheet as of June 30, 2022. As of December 31, 2021, the conditions allowing the holders of the 2024 Notes to convert were met. Therefore, the 2024 Notes were classified as current on the consolidated balance sheet as of December 31, 2021.

The Convertible Notes consisted of the following (in thousands):

	June 30, 2022				December 31, 2021
	2027 Notes		2024 Notes		2027 Notes		2024 Notes

As of June 30, 2022, the if converted value of the 2027 Notes did not exceed the principal amount. As of June 30, 2022, the if converted value of the 2024 Notes exceeded the principal amount by $10.5 million.

Credit agreement

Revolving credit facility

The Company has a $150.0 million credit facility with a maturity date of December 15, 2025 (“2019 Amended Credit Agreement”). The 2019 Amended Credit Agreement provides for an accordion feature that allows the Company to expand the size of the revolving line of credit by an additional $50.0 million, subject to certain conditions, by obtaining additional commitments from the existing lenders or by causing a person acceptable to the administrative agent to become a lender (in each case subject to the terms and conditions set forth in the 2019 Amended Credit Agreement). In June 2022, the Company amended the 2019 Amended Credit Agreement to, among other things, permit the issuance of the 2027 Notes and extend the maturity date of the credit facility to December 2025.

As of June 30, 2022, there were no outstanding borrowings under the 2019 Amended Credit Agreement, there was $150.0 million available for future borrowing, and the Company was in compliance with all the financial covenants. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures, and permitted acquisitions.

Fair Value Measurements

8.Fair value measurements

The accounting guidance for fair value, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The framework for measuring fair value consists of a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows:

Level 1 – Quoted prices in active markets for identical assets and liabilities at the measurement date;

Level 2 – Observable inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The carrying value of cash and cash equivalents, accounts receivable, net and accounts payable approximate fair value due to their short maturities. Interest on the Company’s line of credit is at a variable rate, and as such the debt obligation outstanding approximates fair value.

The carrying value of the Company’s Convertible Notes are at face value less unamortized debt discount and issuance costs. The estimated fair values of the Convertible Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the Convertible Notes on the last trading day of each reporting period. As of June 30, 2022, the estimated fair value of the 2027 Notes and 2024 Notes was $224.0 million and $101.3 million, respectively, and is presented for required disclosure purposes only.

2017 stock-based compensation plan

In 2017, the Company’s board of directors adopted the 2017 Equity Incentive Plan (“2017 Plan”), which was approved by the Company’s stockholders. The 2017 Plan provides for the grant of incentive stock options to the Company’s employees and any parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares, other cash-based awards and other stock-based awards to the Company’s employees, directors and consultants and the Company’s parent, subsidiary, and affiliate corporations’ employees and consultants. The 2017 Plan has 16,999,318 authorized shares of the Company’s Class A common stock reserved for issuance.

The following table summarizes the restricted stock units, or RSUs, awarded under the 2017 Plan for the period:

	Number of RSUs

The total intrinsic value of the 2017 Plan stock options exercised during the six months ended June 30, 2022, was $0.4 million.

2021 Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan (“ESPP”) which allows eligible employees to purchase shares of common stock through payroll deductions and is intended to qualify under Section 423 of the Internal Revenue Code. As of June 30, 2022, the Company had 3,123,191 shares of its common stock available for future issuances under the ESPP.

The purchase price for each share of common stock purchased under the ESPP will be 85% of the lower of (a) the fair market value per share on the first day of the applicable offering period or (b) the fair market value per share on the applicable purchase date.

The Company purchased 76,809 shares of common stock under the ESPP during the six months ended June 30, 2022. As of June 30, 2022, $4.4 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions and is reported in Other accrued expenses and current liabilities. The Company recognized $0.6 million and $1.3 million of stock-based compensation expense related to the ESPP for the three and six months ended June 30, 2022, respectively.

In connection with the acquisition of World Programming in December 2021, per the stock purchase agreement, $29.5 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one-, two- and three-year anniversaries of the certain legal matters being resolved, subject to potential reduction in certain circumstances. The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration.

The estimated post combination expense to the Company as a result of the World Programming business combination was $29.5 million which is recognized on an accelerated method over the employment period. As of June 30, 2022, the weighted average remaining service period is 2.5 years. Once the vesting conditions of the service period are met, the Company will issue shares for each award. Stock-based compensation expense includes $4.5 million and $8.9 million for the three and six months ended June 30, 2022, respectively.

In connection with the acquisition of Powersim Inc. in March 2022, per the stock purchase agreement, $4.3 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies.

The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration. Stock-based compensation expense includes $0.9 million and $1.1 million for the three and six months ended June 30, 2022, respectively.

In connection with the acquisition of Concept Engineering in June 2022, per the stock purchase agreement, $6.0 million of the Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued on the one, and two-year anniversaries of certain matters being resolved, subject to potential reduction in certain circumstances. The accounting treatment for these shares in the context of the business combination is to recognize the expense as a post-combination expense, not as transaction consideration. Stock-based compensation expense includes $0.2 million for both the three and six months ended June 30, 2022.

Net (Loss) Income Per Share

10.Net (loss) income per share

The Company adopted ASU 2020-06 on January 1, 2022, using the modified retrospective method, applicable to its convertible senior notes outstanding as of adoption. The Company has not changed any previously disclosed amounts or provided additional disclosures for comparative periods. ASU 2020-06 requires the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. Under the if-converted method, shares related to convertible senior notes, to the extent dilutive, are assumed to be converted into common stock at the beginning of the period.

Basic net income per share attributable to common stockholders is computed using the weighted average number of shares of common stock outstanding for the period, excluding dilutive securities, stock options, RSUs, and ESPP shares. Diluted net income per share attributable to common stockholders is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of dilutive securities, stock options, RSUs and ESPP shares under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net (loss) income per share amounts (in thousands, except per share data):

World Programming

The Company acquired World Programming Limited and a related company (collectively, “World Programming”) in December 2021. In 2010, SAS Institute, Inc. (“SAS”) filed an action against World Programing in the United States District Court for the Eastern District of North Carolina (the “NC Court”) alleging copyright infringement, breach of contract, fraudulent inducement to contract, and violations of the North Carolina Unfair and Deceptive Trade Practices Act (UDTPA). SAS was unsuccessful on its copyright claims but prevailed on its breach of contract, fraudulent inducement, and UDTPA claims and was awarded damages of $79.1 million in 2016 (the “NC Judgment”). The NC Court subsequently enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States until the NC Judgment was satisfied. At the time that the Company acquired World Programming, World Programming had partially paid the NC Judgment.

In relation to the NC Court order that enjoined World Programming from licensing its WPS Analytics Software to new customers for use in the United States, SAS filed a related matter in California, which resulted in the California court issuing an order that required certain then existing customers of World Programming to direct payment (of their licensing fees for WPS Analytics software) to SAS until the NC Judgment was satisfied.

On January 3, 2022, the Company paid the outstanding balance of $65.9 million on the NC Judgment. Despite payment in full, SAS has asserted that the Company has not satisfied the Judgment. The NC Court scheduled a hearing to address this issue for March 3, 2022 (the “March Hearing”). At the March Hearing, the NC Court confirmed that the Company’s January 3, 2022 payment fully satisfied the NC Judgment, and lifted the injunction that had enjoined World Programming from licensing its WPS Analytics software to new customers for use in the United States. On March 7, 2022, SAS agreed that the California court order was no longer necessary and together with World Programming, filed a joint notice of satisfaction of the NC Judgment with the

California court, thereby allowing customers of World Programming to resume payment of their licensing fees to World Programming directly.

In 2018, SAS filed litigation in the United States District Court for the Eastern District of Texas (the “Texas Court”) asserting that World Programming infringed SAS copyrights and patents. SAS voluntarily dismissed with prejudice its patent claims, and the Texas Court entered judgment in favor of World Programming on the copyright claims. SAS appealed the Texas Court judgment to the United States Court of Appeals for the Federal Circuit (the “Court of Appeals”). Oral arguments were held before the Court of Appeal on January 13, 2022. A decision from the Court of Appeals is pending.

Other legal proceedings

From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. The Company has received, and may in the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to defend the Company, its partners, and its customers by determining the scope, enforceability, and validity of third-party proprietary rights, or to establish and enforce the Company’s proprietary rights.

Effects of proceedings

The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

Segment Reporting [Abstract]

Segment Information

14.Segment information

The Company defines its operating segments as components of its business where separate financial information is available and used by the chief operating decision maker (“CODM”) in deciding how to allocate resources to its segments and in assessing performance. The Company’s CODM is its Chief Executive Officer.

The Company has identified two reportable segments for financial reporting purposes: Software and Client Engineering Services. The primary measure of segment operating performance is Adjusted EBITDA, which is defined as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by management. Adjusted EBITDA includes an allocation of corporate headquarters costs.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Accordingly, the accompanying statements do not include all the information and notes required by GAAP for complete financial statements. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements (and notes thereto) for the year ended December 31, 2021, included in the most recent Annual Report on Form 10-K filed with the SEC.

Use of Estimates

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, valuation of acquired intangible assets in business combinations, the incremental borrowing rate used in the valuation of lease liabilities, the determination of the period of benefit for capitalized costs to obtain a contract, fair value of convertible senior notes, provision for credit loss, tax valuation allowances, liabilities for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price contracts, and stock-based compensation. Actual results could differ from those estimates.

Significant Accounting Policies

Significant accounting policies

There have been no material changes to our significant accounting policies as of and for the six months ended June 30, 2022, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2021.

Recent Accounting Guidance

2.Recent accounting guidance

Accounting standards adopted

Debt – In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for convertible instruments by eliminating certain separation models. Under ASU 2020-06, a convertible debt instrument will generally be reported as a single liability at its amortized cost with no separate accounting for embedded conversion features. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. The Company adopted ASU 2020-06 effective as of January 1, 2022, using the modified retrospective approach. Adoption of the new standard resulted in a decrease to accumulated deficit of $23.9 million, a decrease to additional paid-in capital of $50.0 million, and an increase to convertible senior notes, net of $26.1 million. Interest expense recognized in the current and future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost.

Accounting standards not yet adopted

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. This ASU provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. The amendments in the guidance are optional and effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a material effect on its consolidated financial statements.

Government Assistance – In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This ASU requires certain disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The amendment requires disclosure of information about the nature of the transactions and the related accounting policy used to account for the transactions, information regarding the line items within the consolidated financial statements that are affected by the transactions, and significant terms and conditions of the transactions. ASU 2021-10 is effective for annual periods beginning after December 15, 2021, with early application permitted. The Company is currently evaluating the effect the adoption of this new guidance will have on its consolidated financial statement disclosures.
