Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-based compensation

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 19,460,908 authorized shares of the Company’s Class A common stock reserved for issuance. As of June 30, 2024, the Company had 6,643,204 shares of its common stock available for future issuances under the 2017 Plan.

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


	Number of RSUs
Outstanding as of December 31, 2023		1,086,351
Granted		366,364
Vested		(392,931	)
Forfeited		(13,845	)
Outstanding as of June 30, 2024		1,045,939

The weighted average grant date fair value of the RSUs granted during the six months ended June 30, 2024, was $79.68. The RSUs generally vest in four equal annual installments. Total compensation cost related to nonvested awards not yet recognized as of June 30, 2024, totaled $102.6 million, and is expected to be recognized over a weighted average period of 2.5 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 December 31, 2023		7,602,078		$	52.81		7.8	$	238.3
Granted		417,459		$	79.19
Exercised		(753,504	)	$	49.72
Forfeited		(65,631	)	$	55.28
Outstanding as of June 30, 2024		7,200,402		$	54.63		7.6	$	312.8
Exercisable as of June 30, 2024		3,415,212		$	51.60		6.6	$	158.7

The total intrinsic value of the 2017 Plan stock options exercised during the six months ended June 30, 2024, was $29.1 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. The maximum number of shares available for issuance under the ESPP is 3,200,000 shares of the Company’s Class A common stock. As of June 30, 2024, the Company had 2,767,911 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 issued 64,309 shares of common stock under the ESPP during the six months ended June 30, 2024. As of June 30, 2024 and December 31, 2023, respectively, $4.4 million and $4.2 million had been withheld on behalf of employees for future purchases under the ESPP due to the timing of payroll deductions and was reported in current liabilities. Stock-based compensation expense related to the ESPP was $0.7 million and $1.4 million, respectively, for the three and six months ended June 30, 2024, and $0.6 million and $1.2 million, respectively, for the three and six months ended June 30, 2023.

Income Tax Disclosure [Abstract]

Income Taxes

Income taxes

The Company’s income tax expense and effective tax rate for the three and six months ended June 30, 2024 and 2023, were as follows (in thousands, except percentages):


	Three Months Ended June 30,						Six Months Ended June 30,
	2024			2023			2024			2023
Income tax (benefit) expense	$	(610	)	$	8,678		$	6,159		$	17,910
Effective tax rate		11	%		(64	%)		35	%		(283	%)

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 change in the effective tax rate for the six months ended June 30, 2024 as compared to June 30, 2023, was primarily attributable to the effects of tax elections made by the Company during the third quarter of 2023 that have a prospective impact on the Company’s tax expense in 2024. The Company's effective tax rate for the six months ended June 30, 2024 and 2023 also includes net discrete benefit of $0.3 million and expense of $11.6 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.

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.

Recent Accounting Guidance	6 Months Ended
Recent Accounting Guidance	Jun. 30, 2024
Accounting Changes and Error Corrections [Abstract]
Recent Accounting Guidance	2. Recent accounting guidance 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. In October 2022, the FASB Board voted to amend the sunset date of ASU 2020-04 to December 31, 2024. 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. Segment Reporting – In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The update is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant expenses. The ASU requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (CODM), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. The ASU also requires all annual disclosures currently required by Topic 280 to be included in interim periods. The update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting the updated standard. Income Taxes – In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which updates income tax disclosures related to the tax rate reconciliation and requires disclosure of income taxes paid by jurisdiction. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied prospectively; however, retrospective application is permitted. The Company is currently evaluating this ASU to determine the effect on its related disclosures.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Acquisitions

2024 Acquisitions

During the three months ended June 30, 2024, the Company completed two acquisitions that were accounted for as business combinations under the acquisition method. The preliminary aggregate transaction consideration of $14.3 million was allocated to assets acquired and liabilities assumed at their estimated fair values. The fair values assigned to the identifiable intangible assets acquired were based on estimates and assumptions determined by management. The allocation included $7.2 million to developed technology, $2.7 million to customer relationships, $0.4 million to net liabilities acquired and $4.8 million to goodwill, which is deductible for tax purposes. All goodwill was 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 financed with cash on hand. 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 these 2024 acquisitions were not material.

Prior acquisitions

The Company recognized a $0.1 million loss and a $0.2 million loss, respectively, for the three and six months ended June 30, 2024, and a $1.0 million loss and an $8.0 million loss, respectively, for the three and six months ended June 30, 2023, from a mark-to-market adjustment of contingent consideration associated with a prior year acquisition. The mark-to-market adjustments were included in Other operating (income) expense, net in the consolidated statements of operations.

Cash, cash equivalents and restricted cash

The Company considers all highly liquid investments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. Restricted cash is included in Other long-term assets on the consolidated balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets that sum to the total of the amounts reported in the consolidated statement of cash flows (in thousands):


	June 30,		December 31,

Earnings (loss) per share

Earnings Per Share [Abstract]

Earnings (loss) per share

Basic (loss) earnings 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 (loss) earnings 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 Company applies the if-converted method for 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.

The following table sets forth the computation of the numerators and denominators used in the basic and diluted (loss) earnings per share amounts (in thousands, except per share data):

Diluted (loss) earnings per share	$	(0.06	)	$	(0.28	)	$	0.13	$	(0.30	)

(1)

Interest expense related to the convertible notes has been excluded from the numerator for diluted earnings per share because its effect would have been anti-dilutive.

Anti-dilutive shares excluded from the computation of diluted (loss) earnings per share were as follows (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,

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 2027 Notes bear interest at a rate of 1.750% per year, payable semi-annually in arrears on June 15 and December 15 of each year, which commenced on December 15, 2022. The 2027 Notes mature on June 15, 2027, unless, earlier repurchased or redeemed by the Company or converted pursuant to their terms. 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 its Class A common stock.

During the period ended June 30, 2024, the conditions allowing holders of the 2027 Notes to convert were not met. Therefore, the 2027 Notes remained classified as long-term debt on the consolidated balance sheet as of June 30, 2024.

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 (“CES”). 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, asset impairment charges and other special items as determined by management. Corporate headquarter costs are allocated to each segment.

Organization and Description of Business (Policies)	6 Months Ended
Organization and Description of Business (Policies)	Jun. 30, 2024
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, 2023, 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, useful lives of intangible assets, 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, 2024, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2023.
Change in Presentation of Revenue and Cost of Revenue	Change in Presentation of Revenue and Cost of Revenue Effective in the first quarter of 2024, the Company changed the presentation of revenue and cost of revenue in its Consolidated Statements of Operations to combine the financial statement line items (“FSLIs”) labeled “Software related services”, “Client engineering services” and “Other” into one FSLI labeled “Engineering services and other”. The change in presentation has been applied retrospectively and does not affect the software revenue, total revenue, software cost of revenue, or total cost of revenue amounts previously reported or have any effect on segment reporting.
Recent Accounting Guidance	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. In October 2022, the FASB Board voted to amend the sunset date of ASU 2020-04 to December 31, 2024. 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. Segment Reporting – In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The update is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant expenses. The ASU requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (CODM), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. The ASU also requires all annual disclosures currently required by Topic 280 to be included in interim periods. The update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting the updated standard. Income Taxes – In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which updates income tax disclosures related to the tax rate reconciliation and requires disclosure of income taxes paid by jurisdiction. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied prospectively; however, retrospective application is permitted. The Company is currently evaluating this ASU to determine the effect on its related disclosures.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Description of Business

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 intelligence enabling organizations across broad industry segments to drive smarter decisions in an increasingly connected world. Altair delivers software and cloud solutions in the areas of simulation, high-performance computing (“HPC”), data analytics, and artificial intelligence (“AI”). Altair’s products and services leverage computational science to drive innovation and intelligent decisions for a more connected, safe, and 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, 2023, 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, useful lives of intangible assets, 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, 2024, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2023.

Change in Presentation of Revenue and Cost of Revenue

Effective in the first quarter of 2024, the Company changed the presentation of revenue and cost of revenue in its Consolidated Statements of Operations to combine the financial statement line items (“FSLIs”) labeled “Software related services”, “Client engineering services” and “Other” into one FSLI labeled “Engineering services and other”. The change in presentation has been applied retrospectively and does not affect the software revenue, total revenue, software cost of revenue, or total cost of revenue amounts previously reported or have any effect on segment reporting.

Fair Value Measurements

6 Months Ended

Jun. 30, 2024

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 2027 Notes are at face value less unamortized issuance costs. The estimated fair values of the 2027 Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the 2027 Notes on the last trading day of each reporting period. As of June 30, 2024, the estimated fair value of the 2027 Notes was $334.9 million, and is presented for required disclosure purposes only. For further information on the Convertible Notes, see Note 6. – Debt.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
