Fair Value Measurements

6 Months Ended

Jun. 30, 2024

Cash equivalents

At June 30, 2024 and December 31, 2023, highly liquid money market funds of $10.4 million and $0.4 million, respectively, were valued using Level 1 of the fair value hierarchy, quoted prices in active markets for identical assets, and are included in cash equivalents.

Short-term investments in held-to-maturity securities

As of June 30, 2024 and December 31, 2023, the Company had purchased Treasury Bills with maturities ranging from 3 to 12 months, which the Company intends to hold until maturity and has classified as held-to-maturity securities. The held-to-maturity securities are recorded at amortized cost totaling $435.9 million including gross accrued interest of $10.1 million as of June 30, 2024. As of June 30, 2024, the fair value and gross unrealized loss on the held-to-maturity securities was $435.5 million and $0.4 million respectively.

As of December 31, 2023, the amortized cost of the held-to-maturity securities totaled $518.7 million including gross accrued interest of $8.9 million. As of December 31, 2023, the fair value and gross unrealized loss on the held-to-maturity securities $519.0 million and $0.3 million respectively.

These treasury bills were valued using Level 1 of the fair value hierarchy, quoted prices in active markets for identical assets, and are included in short-term investments. The carrying value of our investments is reviewed quarterly for changes in circumstances or the occurrence of events that suggests an investment may not be fully recoverable.

Sales based earnout liability

The estimated fair value of the sales based earnout liability is determined using a Monte Carlo simulation model using significant unobservable fair value inputs and is therefore classified as a Level 3 measurement. The assumptions used in the calculation are based on the revenue projections over the term of the contingent earn-out period, expected volatility, and discount rate. The estimates of fair value are uncertain and changes in any of the estimated inputs used will result in significant adjustments to the fair value. As of June 30, 2024, the Company used a volatility rate of 20%, risk free rate ranging from 4.3% to 5.4%, and an expected term ranging from 0.13 years to 4.38 years.

The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities:


	Amount
Fair value as of January 1, 2024	$	103,461
Change in the fair value during the year recorded to acquisition related costs	3,311
Payments made during the period	(5,618)
Fair value as of June 30, 2024	$	101,154

There were no transfers between Level 1, Level 2, and Level 3 categories during any of the periods presented.

Stockholders' Equity

Stockholders’ Equity

At-The-Market offering

On February 27, 2024, the Company entered into a Sales Agreement ("Sales Agreement"), with Stifel, Nicolaus & Company, Incorporated ("Stifel"), under which the Company may offer and sell from time to time at its sole discretion, up to an aggregate of 1,200,000 shares of its common stock, par value $0.0001 per share, through Stifel acting as its sales agent. The Company used the net proceeds from the shares of common stock offered and sold to replenish funds expended to satisfy anticipated tax withholding and remittance obligations related to the net settlement upon vesting of restricted stock unit awards (“RSU”) granted to employees under the equity incentive plans. The Company has filed a prospectus supplement pursuant to the Sales Agreement for the offer and sale of up to an aggregate of 1,200,000 shares of its common stock. Subject to the terms and conditions of the Sales Agreement, Stifel will sell the common stock from time to time, based upon instructions from the Company. The Company agreed to pay Stifel a commission of up to 3% of the gross sales proceeds of any common stock sold through Stifel under the Sales Agreement.

During the three months ended June 30, 2024, the Company sold 100,000 shares of its common stock through Stifel under the Sales Agreement at a weighted average price of $127.18 per share resulting in net proceeds to the Company of $12.3 million, after deducting underwriting discounts and commissions of $0.3 million and offering costs of $0.1 million. During the six months ended June 30, 2024, the Company sold 132,500 shares of its common stock through Stifel under the Sales Agreement at a weighted average price of $118.69 per share resulting in net proceeds to the Company of $15.0 million, after deducting underwriting discounts and commissions of $0.3 million and deferred offering costs of $0.4 million.

Equity Incentive Plans

The following table summarizes the RSU, performance based restricted stock units ("PRSU"), and multi-year performance restricted stock units ("MYPSU") activity for the three and six months ended June 30, 2024:


	RSU Number of Shares	Grant Date Fair Value per share		PRSU Number of Shares	Grant Date Fair Value per share		MYPSU Number of Shares	Grant Date Fair Value per share

Unvested at December 31, 2023	1,238,417	$	103.8	108,622	$	145.5	285,880	$	88.6

In March 2024, the Compensation Committee approved target bonus amounts based on the achievement of revenue and individual performance goals for the fiscal year 2024 (the "2024 Goals"). The awards for the actual payouts are granted in the quarter following the end of the performance period. The target bonuses were granted based on a fixed dollar amount to be settled in RSUs on the vesting date and hence the awards have been classified as liability-based awards until settled. Such expense is included in the non-cash adjustment within stock-based compensation expense on the condensed consolidated cash flow statements. The liability of $0.9 million for 2024 Goals was recorded as accrued expenses and other current liabilities in the condensed consolidated balance sheet as of June 30, 2024.

In March 2024, the Compensation Committee of the Company approved PRSUs for the fiscal year 2024 with performance goals based on the achievement of relative total stockholder return with a three year performance period (the "2024 TSR PRSU Goals"). The grant-date fair value of each PRSU was determined using Monte Carlo simulation model. The assumptions used in the Monte Carlo simulation included expected volatility of 74.7%, risk free rate of 4.5%, no expected dividend yield and expected term of 2.8 years. The Company recognizes the expense related to the 2024 TSR PRSU Goals on a graded-vesting method over the requisite performance period. These grants are included in the PRSU awards granted in the table above.

The Company also operates a bonus plan for certain employees which are based on a fixed dollar amount to be settled in RSUs. These awards are categorized as liability-based awards until settled. Once settled, these awards are reflected as RSU granted in the above table. Such expense is included in the non-cash adjustment within stock-based compensation expense on the condensed consolidated cash flow statements. The liability of $1.0 million was recorded as accrued expenses and other current liabilities in the condensed consolidated balance sheet as of June 30, 2024.

Weighted average shares used to compute basic net loss per share	22,997		22,074		22,881		21,934
Dilutive effect of employee equity incentive plans	—		—		—		—
Weighted average shares used to compute diluted net loss per share	22,997		22,074		22,881		21,934
Net loss attributable to common stockholders per share, basic	$	(1.16)	$	(1.17)	$	(2.42)	$	(1.93)
Net loss attributable to common stockholders per share, diluted	$	(1.16)	$	(1.17)	$	(2.42)	$	(1.93)

Potential dilutive securities include dilutive common shares from share-based awards attributable to the assumed exercise of restricted stock unit awards using the treasury stock method. Under the treasury stock method, potential common shares outstanding are not included in the computation of diluted net income per share if their effect is anti-dilutive.

Anti-dilutive potential shares from share-based awards are excluded from the calculation of diluted earnings per share if either their exercise price exceeded the average market price during the period, or the share-based awards were determined to be anti-dilutive based on applying the treasury stock method. During the three months ended June 30, 2024 and 2023, the Company had 766,620 and 1,267,359 potential shares from share-based awards that are anti-dilutive, respectively. During the six months ended June 30, 2024 and 2023, the Company had 698,148 and 1,353,845 potential shares from share-based awards that are anti-dilutive, respectively.

Income Taxes

6 Months Ended

Jun. 30, 2024

Income Tax Disclosure [Abstract]

Income Taxes

The quarterly provision for income taxes is based on applying the estimated annual effective tax rate to the year to date pre-tax income, plus any discrete items. The Company updates its estimate of its annual effective tax rate at the end of each quarterly period. The estimate takes into account annual forecasted income before income taxes, the geographic mix of income before income taxes and any significant permanent tax items.

The following table presents the provision for income taxes and the effective tax rates for the three and six months ended June 30, 2024 and 2023:


	Three Months Ended June 30,						Six Months Ended June 30,
	2024			2023			2024			2023

	(in thousands)
Loss before income taxes	$	(26,787)		$	(25,899)		$	(55,478)		$	(42,319)
Income tax benefit (expense)	18			(23)			5			(93)
Effective tax rate	0		%	0		%	0		%	0		%

The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits and the tax impact of non-deductible expenses, existence of full valuation allowance on its deferred tax assets, and other permanent differences between income before income taxes and taxable income.

A valuation allowance is established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company regularly assesses its valuation allowance against deferred tax assets on a jurisdiction by jurisdiction basis. The Company considers all available positive and negative evidence, including future reversals of temporary differences, projected future taxable income, tax planning strategies and recent financial results. Based on management’s assessment of the realizability of deferred tax assets, the Company continues to maintain a full valuation reserve on its deferred tax assets as of June 30, 2024.

The income tax provision was less than $0.1 million for both the three and six months ended June 30, 2024 and 2023. The effective tax rate was less than 1% for both the three and six months ended June 30, 2024 and 2023. The provision for income taxes is primarily related to the foreign subsidiaries’ local country obligations. The U.S. effective tax rate is less than 1% and is due to minimum state tax. There is no federal provision for income taxes as the Company has sufficient carryforward of net operating losses to offset any operating income earned since inception and has projected an operating loss in the current year.

As of June 30, 2024 and December 31, 2023, the Company had $2.3 million and $2.3 million, respectively, of total unrecognized tax benefits. If the Company is able to eventually recognize these uncertain tax positions, none of the unrecognized benefits would reduce the Company’s effective tax rate due to the full valuation allowance on the Company’s deferred tax assets.

The Company’s policy is to record interest and penalties related to unrecognized tax benefits as income tax expense. For the three and six months ended June 30, 2024 and 2023, the Company recorded immaterial amounts related to the accrual of interest and penalties.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Leases

The Company leases office space in California, Michigan, Malaysia, Japan, Taiwan, the Netherlands, Finland, Ukraine, and India, all under non-cancellable operating leases with various expiration dates through May 2029.

The remaining lease terms vary from a few months to 5 years. For certain of its leases the Company has options to extend the lease term for periods varying from one to five years.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Legal Matters

From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with legal counsel, the need to record a liability for litigation and contingencies. Accrual estimates are recorded when and if it is determined that such a liability for litigation and contingencies are both probable and reasonably estimable. We did not have any amounts accrued towards these matters as of June 30, 2024

Indemnification

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify other parties to such agreements with respect to certain matters. Typically, these obligations arise in the context of contracts that the Company has entered into, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants or terms and conditions related to such matters as the sale and/or delivery of its products, title to assets sold, certain intellectual property claims, defective products, and specified environmental matters. Further, the Company’s obligations under these agreements may be limited in terms of time, amount, or the scope of its responsibility and in some instances, the Company may have recourse against third-parties for certain payments made under these agreements. It is not possible to predict the maximum potential amount of future payments under these agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, the Company has had no material indemnification claims under these agreements.

Purchase Commitments

The Company purchases components from a variety of suppliers and uses several contract manufacturers to provide manufacturing services for its products. During the normal course of business, in order to manage manufacturing lead times and to help ensure adequate component supply, the Company enters into agreements with the Company’s contract manufacturers and suppliers that allow them to procure inventory based upon criteria as defined by the Company. In addition, the Company has a multi-year agreement to purchase minimum quantities of MEMS wafers and is responsible for research and development, tooling, and samples cost under the agreement. A portion of the Company’s reported purchase commitments arising from these agreements consists of firm, non-cancelable purchase commitments. In certain instances, these agreements allow the Company the option to cancel, reschedule, and adjust the Company’s requirements based on its business needs prior to when production starts. However, in situations where the Company is unable to cancel, reschedule, or adjust the purchase commitment due to changing customer demand, excess inventories could result in material inventory provisions. Total future non-cancelable purchase commitments as of June 30, 2024 were as follows:
