FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

The fair value of the Company’s financial assets and liabilities is determined in accordance with the fair value hierarchy established in FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy of ASC 820 requires an entity to maximize the use of observable inputs when measuring fair value and classifies those inputs into three levels:

Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs, other than Level 1 inputs, which are observable either directly or indirectly or can be corroborated by observable market data using quoted prices for similar assets or liabilities.

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

The Company's financial instruments that are not remeasured at fair value include accounts receivable, prepaid and other current assets, accounts payable, accrued expenses, and other current liabilities. The carrying values of these financial instruments approximate their fair values.

The Company’s financial assets and liabilities measured at fair value on a recurring basis and the level of inputs used for such measurements were as follows (in thousands):


	Fair Value Measured as of March 31, 2024 Using:
	Adjusted Cost		Unrealized losses		Fair Value		Cash and Cash Equivalent		Marketable Securities

The Company’s financial assets and liabilities subject to fair value procedures were comprised of the following:

Money Market Funds: The Company holds financial assets consisting of money market funds. These securities are valued using observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Marketable Securities: The Company holds financial assets consisting of fixed-income U.S. government agency securities, corporate bonds, and commercial paper. The securities are valued using prices from independent pricing services based on quoted prices of identical instruments in less active or inactive markets. Additionally, quoted prices of similar instruments in active market or industry models using data inputs such as interest rates and prices that can be directly observed or corroborated in active markets are used to value marketable securities.

Derivative Warrant Liability: On September 15, 2022, the Company entered into a convertible note agreement with a face value of $10,500 (the "2022 Note"). The Company’s derivative warrant liability includes the warrants that were issued by the Company as part of the 2022 Note. The warrants are recorded on the condensed consolidated balance sheets at fair value. The fair value is based on unobservable inputs, which represent Level 3 measurements within the fair value hierarchy. The fair value estimate of the warrants was based on a Monte-Carlo simulation model. Inherent in a Monte-Carlo simulation model are assumptions related to price, volatility, risk-free interest rate, term to expiration, and dividend yield. The price is based on the publicly traded price of the Company’s common stock as of the measurement date. The Company estimated the volatility for the warrants based on the historical and implied volatilities of the Company's publicly traded common stock. The risk-free interest rate is based on interpolated U.S. Treasury rates, commensurate with a similar term to the warrants. The term to expiration was calculated as the contractual term of the warrants of 4 years. Finally, the Company does not currently anticipate paying a dividend. Any changes in these assumptions can change the valuation significantly. Changes in fair value are recognized in other income (expense) for each reporting period. Derivative Warrant Liability is included within other noncurrent liabilities on the condensed consolidated balance sheets.

Private Placement Warrant Liability: The Private Placement Warrants are recorded on the condensed consolidated balance sheets at fair value. The fair value is based on observable Level 2 inputs, specifically, the observable input of the Company's public warrants, as terms of both warrants are substantially similar. Any changes in the fair value of the liability are reflected in other income (expense), net, on the condensed consolidated statements of operations and comprehensive loss. Private Placement Warrant liability is included within other noncurrent liabilities on the condensed consolidated balance sheets.

For the three months ended March 31, 2024, there were no net transfers between Level 1 and Level 2 inputs.

The following table presents a summary of the changes in fair value of the Company’s Level 3 financial instruments for the three months ended March 31, 2024 (in thousands):


	Derivative Warrant Liability
Balance at December 31, 2023	$	26


Change in fair value included in other income (expense), net	(2)

Balance at March 31, 2024	$	24

The key inputs into the Monte-Carlo simulation model for the derivative warrant liability valued at March 31, 2024 are as follows:


	March 31, 2024
Expected term (years)	2.4
Expected volatility	234.8		%
Risk-free interest rate	4.5		%
Dividend yield	—		%
Exercise price	$	105.00

If factors or assumptions change, the estimated fair values could be materially different. The value of the Company’s derivative warrant liability would increase if a higher risk-free interest rate was used, and would decrease if a lower risk-free interest rate was used. Similarly, a higher volatility assumption would increase the value of the liability, and a lower volatility assumption would decrease the value of the liability.

	Mar. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Principle of Consolidation and Liquidity	Principle of Consolidation and Liquidity The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments which potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, and marketable securities, and accounts receivable. The Company places its cash and cash equivalents with major financial institutions, which management assesses to be of high credit quality, to limit the exposure of each investment. The Company’s marketable securities have investment grade ratings when purchased which mitigates risk. The Company’s accounts receivable are derived from customers located in the U.S., Europe, and Asia-Pacific. The Company mitigates its credit risks by performing ongoing credit evaluations of its customers’ financial conditions. The Company generally does not require collateral.
Recently Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board ("FASB"), issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures to increase the transparency and usefulness of income tax information through improvements to the income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The guidance is effective for fiscal years beginning after December 15, 2024. The Company is currently in the process of evaluating the effects of the new guidance. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires public companies, including entities with a single reportable segment, to disclose information about their reportable segments’ significant expenses and other items on an interim and annual basis to provide more transparency about the expenses they incur from revenue generating business units. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material effect on its consolidated financial statements.

CONVERTIBLE NOTES	3 Months Ended
CONVERTIBLE NOTES	Mar. 31, 2024
Debt Disclosure [Abstract]
CONVERTIBLE NOTES	CONVERTIBLE NOTES 2022 Convertible Note On September 14, 2022, the Company entered into a Securities Purchase Agreement, or SPA, with an investor allowing for the sale and issue of up to two convertible notes, each with a principal balance of $10,500 and gross cash proceeds of $10,000, for a total of $20,000 in proceeds between the two issuances (each, a "Note Closing"). The first Note Closing ("First Closing") occurred on September 15, 2022, and the Company entered into a Senior Unsecured Convertible Note with the investor pursuant to which the Company issued to the investor one convertible note ("2022 Note") with a principal balance of $10,500 for net cash proceeds of $9,850. As part of the First Closing, the Company also issued warrants to the investor. The second Note Closing ("Second Closing") could have occurred up to March 15, 2024, upon which the Company's right to effect a Second Closing automatically terminated. As of March 15, 2024, the Company did not effect a Second Closing. The 2022 Note bore interest at an annual rate of 5.0%, in addition to an original issue discount of 4.76%, and had an initial a maturity date of March 15, 2024 (“Maturity Date”). Beginning December 14, 2022, and the first trading day of each subsequent month (each a "Monthly Redemption Date" or an "Installment Date"), the Company was required to redeem the Monthly Redemption Amount until the 2022 Note was fully redeemed. The Monthly Redemption Amount, in most instances, was 1/15th of the original principal amount, plus any amount accelerated pursuant to the 2022 Note, accrued but unpaid interest, and late fees, if any. The principal and interest could be settled in cash or, so long as certain equity conditions were met and at the option of the Company, shares of common stock and was payable together with the Monthly Redemption Amount. If the Company elected to settle the Monthly Redemption Amount in shares of common stock, the number of shares to be settled was based on an Installment Conversion Price equal to the lower of (i) $2.50 or (ii) 95% of the lowest daily volume weighted average price of the common stock during the five (5) trading days immediately preceding the applicable Monthly Redemption Date. If the Company elected to settle the Monthly Redemption Amount in cash, the Monthly Redemption Amount would have included a 5% premium. The investor was permitted to accelerate up to four (4) Monthly Redemption Amounts in any calendar month (each, an "Acceleration," and each such amount, an "Acceleration Amount", and the Conversion Date of any such Acceleration, each an "Acceleration Date") at the Acceleration Conversion Price, subject to a $2,800 limit per month. The Acceleration Conversion Price was the lower of (i) the Installment Conversion Price for such current Installment Date or (ii) the greater of $9.00 and 95% of the lowest daily volume weighted average price of the Common Stock during the five (5) trading days immediately preceding the Acceleration Date. If either the relevant Installment Conversion Price or Acceleration Conversion Price, as applicable, was less than $9.00 per share, then a Conversion Floor Price Condition existed and the Company must deliver to the investor the Conversion Installment Floor Amount in cash, in addition to the required number of shares, which were valued at $9.00 regardless of the actual trading price of the Company’s shares. The Conversion Installment Floor Amount was an amount in cash equal to the product obtained by multiplying (A) the higher of (i) the highest price that the common stock traded at on the Trading Day immediately preceding the relevant Share Delivery Date and (ii) the applicable Installment Conversion Price or Acceleration Conversion Price and (B) the difference obtained by subtracting (i) the number of shares of common stock delivered to the investor on the applicable Share Delivery Date with respect to such Conversion from (ii) the quotient obtained by dividing (x) the applicable Installment or Acceleration amount subject to such Conversion, by (y) the applicable Installment Conversion Price. Interest payments were also trued-up in cash when the value of the Company’s shares was below $9.00 per share. The Company elected to apply the fair value option to the measurement of the 2022 Note. As a result of adopting the fair value option, no embedded derivatives were bifurcated from the 2022 Note. The Company classified the 2022 Note as a liability at fair value and remeasured the 2022 Note to fair value at each reporting period. The fair value measurement included the assumption of accrued interest and expense and thus a separate amount was not reflected on the condensed consolidated statement of operations. The 2022 Note was fully settled through Monthly Redemptions and Accelerations in 2023. As part of the debt extinguishment, the Company reclassified the accumulated change in fair value due to instrument-specific credit risk out of accumulated other comprehensive loss on the condensed consolidated balance sheet and into interest expense and other on the condensed consolidated statement of operations.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

REVENUE

Revenue from Contract with Customer [Abstract]

REVENUE

Sale of Prototypes

The Company recorded revenue for prototype sales of $20 and $125 in the three months ended March 31, 2024 and 2023, respectively. The Company does not incur significant contract costs in fulfilling or obtaining their contracts with customers.

Development Contracts

The Company has entered into research and development contracts with companies primarily in the automotive industry. The Company assessed the number of performance obligations associated with the promises under each agreement, primarily the delivery of customized 4SightTM perception-related goods and services, and recognized $0 and $511 in revenue for performance obligations satisfied during the three months ended March 31, 2024 and 2023, respectively, in the condensed consolidated statements of operations and comprehensive loss.

Disaggregation of Revenue

The Company recognized the following revenues by geographic area based on the primary billing address of the customer and by the timing of the transfer of goods or services to customers (point in time or over time), as it believes such criteria best depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors. Total revenue based on the disaggregation criteria described above are as follows (in thousands):


	Three months ended March 31,
	2024		2023
Revenue by primary geographical market:
United States	$	15	$	547
Europe	5		32
Asia-Pacific	—		57
Total	$	20	$	636

Revenue by timing of recognition:
Recognized at a point in time	$	20	$	125
Recognized over time	—		511
Total	$	20	$	636

Contract Liabilities

The Company does not have any contract liabilities as of March 31, 2024 and December 31, 2023.

The following table shows the significant changes in contract liabilities balance for the three months ended March 31, 2024 and 2023 (in thousands):


	Three months ended March 31,
	2024		2023
Beginning balance	$	—	$	987
Revenue recognized that was included in the contract liabilities beginning balance	—		(511)

Ending balance	$	—	$	476

Remaining Performance Obligations

Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied. It includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods and does not include contracts where the customer is not committed. The customer is not considered committed where they are able to terminate for convenience without payment of a substantive penalty under the contract. Additionally, as a practical expedient, the Company has not disclosed the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The contract liabilities balance represents the remaining performance obligations for contracts with an original duration of greater than one year.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

The Company uses the Monte-Carlo simulation model to estimate the grant date fair value of awards with a market condition, which requires the input of subjective assumptions such as expected term, expected stock price volatility, risk-free interest rate and dividend yield as discussed below.

Expected Term—The expected term for awards with a market condition is the length of time from the grant date to the date the market condition expires.

Expected Volatility—Expected volatility is estimated using a combination of the average historical volatility of the Company's own stock and those of comparable companies’ stock at the time of the grant.

Risk-Free Interest Rate—The risk-free interest rates are based on US Treasury yields in effect at the grant date for notes with comparable terms as the awards.

Dividend Yield—The expected dividend-yield assumption is based on the Company’s current expectations about its anticipated dividend policy.

There were no awards granted with a market condition during the three months ended March 31, 2024.

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AEye (the “Company” or “AEye”) is a provider of high-performance, active lidar systems for vehicle autonomy, advanced driver-assistance systems (ADAS), and smart industrial applications. AEye’s software-definable 4SightTM Intelligent Sensing Platform combines solid-state active lidar and integrated deterministic artificial intelligence to capture more intelligent information with less data, enabling faster, more accurate, and more reliable perception of the surroundings. AEye, Inc., formerly known as CF Finance Acquisition Corp. III, (“CF III”) was originally incorporated in Delaware on March 15, 2016 under the name CF SPAC Re Inc. On February 17, 2021, AEye Technologies, Inc., then known as AEye, Inc., entered into an Agreement and Plan of Merger with CF III. Based on CF III’s business activities, it was a “shell company” as defined under the Securities Exchange Act of 1934, as amended. On August 16, 2021, the business combination contemplated by the Agreement and Plan of Merger was closed and CF III changed its name to AEye, Inc. The Company’s common stock and public warrants are listed on the Nasdaq Stock Market LLC (“Nasdaq”) under the symbols “LIDR” and “LIDRW”, respectively. Unless otherwise specified, “we,” “us,” “our,” “AEye,” and the “Company” refers to AEye, Inc. Unaudited Condensed Consolidated Financial Statements The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included. The accompanying interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2023 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Principle of Consolidation and Liquidity The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company has funded its operations primarily through the business combination and issuances of stock. As of March 31, 2024, the Company’s existing sources of liquidity included cash, cash equivalents, and marketable securities of $28,909. ASC 205-40, Presentation of Financial Statements - Going Concern, requires management to assess an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. In each reporting period, including interim periods, an entity is required to assess conditions known and reasonably knowable as of the financial statement issuance date to determine whether it is probable an entity will not meet its financial obligations within one year from the financial statement issuance date. As is common in early-stage companies with limited operating histories, the Company is subject to risks and uncertainties such as its ability to develop and commercialize its products; produce and deliver lidar and software products meeting acceptable performance metrics; attract new and retain existing customers; develop, obtain, or progress strategic partnerships; secure an automotive OEM design win; secure additional capital to support the business plan; and other risks and uncertainties such as those described in Part II, Item 1A of this Quarterly Report on Form 10-Q. Since its inception, the Company has incurred net losses and negative cash flows from operations. As of March 31, 2024, the Company had an accumulated deficit of $347,854. For the three months ended March 31, 2024 and 2023, the Company incurred a net loss of $10,219 and $26,265, respectively, and the Company had net cash outflows from operating activities of $7,885 and $17,195, respectively. As of March 31, 2024, the Company had $28,909 of cash and marketable securities. As the Company is still in its early stages, it is expected to incur additional operating losses and negative cash flows as it continues to focus on achieving commercialization of its lidar solutions. When conditions and events, in the aggregate, impact an entity’s ability to continue as a going concern, management evaluates the mitigating effect of its plans to determine if it is probable that the plans will be effectively implemented, and, when implemented, the plans will mitigate the relevant conditions or events. The decision in late 2023 by the Company's former Tier 1 partner, Continental AG, to discontinue its joint lidar development program with the Company, may have a material and adverse effect on the Company's business, which is predicated on licensing its lidar designs and other intellectual property to Tier 1 partners. Primarily, the Company is dependent upon raising additional capital to provide the cash necessary to continue the Company's ongoing operations. Should the Company not be able to do so, the Company will require alternative sources of liquidity to continue its operations over the next 12 months. The Company plans to adjust spending in order to preserve and extend liquidity, and has plans which would further reduce operating expenses and cash outlays. The Company believes that these plans alleviate substantial doubt about the Company's ability to continue as a going concern, which will result in adequate cash flows to support its ongoing operations for at least one year following the date these financial statements are issued. Based upon the results of management’s assessment, which has been performed as of May 14, 2024, these condensed consolidated financial statements have been prepared on a going concern basis. Reverse Stock Split On December 27, 2023, the Company effected a 1-for-30 reverse stock split of its issued and outstanding shares of common stock (the "Reverse Stock Split"). Pursuant to the Reverse Stock Split, every thirty (30) shares of issued and outstanding shares of common stock were combined into one (1) share of common stock. The Company did not issue fractional shares in connection with the Reverse Stock Split. Stockholders who were otherwise entitled to fractional shares of common stock were instead entitled to receive a proportional cash payment. The number of shares of common stock issuable under our equity incentive plans and exercisable under the outstanding warrants were also proportionately adjusted. In connection with the Reverse Stock Split, there was no change to the number of shares authorized or in the par value per share of common stock of $0.0001. Accordingly, all historical per share data, number of shares issued and outstanding, stock awards, and other common stock equivalents for the periods presented in the accompanying condensed consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the Reverse Stock Split. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, and marketable securities, and accounts receivable. The Company places its cash and cash equivalents with major financial institutions, which management assesses to be of high credit quality, to limit the exposure of each investment. The Company’s marketable securities have investment grade ratings when purchased which mitigates risk. The Company’s accounts receivable are derived from customers located in the U.S., Europe, and Asia-Pacific. The Company mitigates its credit risks by performing ongoing credit evaluations of its customers’ financial conditions. The Company generally does not require collateral. Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board ("FASB"), issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures to increase the transparency and usefulness of income tax information through improvements to the income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The guidance is effective for fiscal years beginning after December 15, 2024. The Company is currently in the process of evaluating the effects of the new guidance. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires public companies, including entities with a single reportable segment, to disclose information about their reportable segments’ significant expenses and other items on an interim and annual basis to provide more transparency about the expenses they incur from revenue generating business units. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material effect on its consolidated financial statements.
