CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains statements that SES AI Corporation (“the Company”) believes are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, without limitation, statements relating to expectations for future financial performance, business strategies or expectations for our business. These statements are based on the beliefs and assumptions of the management of the Company. Although the Company believes that its plans, intentions and expectations reflected in or suggested by these forward-looking statements are reasonable, it cannot provide assurance that it will achieve or realize these plans, intentions or expectations. These statements constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. When used in this Quarterly Report, words such as “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “strive,” “target,” “will,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

You should not place undue reliance on these forward-looking statements. Should one or more of a number of known and unknown risks and uncertainties materialize, or should any of our assumptions prove incorrect, the Company’s actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include, but are not limited to the following risks:

● risks related to the development and commercialization of SES’s battery technology and the timing and achievement of expected business milestones;

● risks relating to the uncertainty of achieving and maintaining profitability;

● risks relating to the uncertainty of meeting future capital requirements;

● the ability of SES to integrate its products into electric vehicles (“EVs”);

● the risk that delays in the pre-manufacturing development of the Company’s battery cells could adversely affect our business and prospects;

● potential supply chain difficulties;

● the Company’s ability to engage target original equipment manufacturers (“OEMs”) customers successfully and integrate our products into EVs manufactured by OEM customers;

● the ability to obtain raw materials, components or equipment through new or existing supply relationships;

● the Company’s risks resulting from joint development agreements and other strategic alliances and investments; product liability and other potential litigation, regulation and legal compliance;

● the Company’s ability to attract, train and retain highly skilled employees and key personnel;

● the uncertainty in global economic conditions and risks relating to health epidemics, including the COVID-19 pandemic and any operational interruptions;

● developments in alternative technology or other fossil fuel alternatives;

● the Company’s risks related to intellectual property;

● business, regulatory, political, operational, financial and economic risks related to the Company’s business operations outside the United States;

● the Company has identified material weaknesses in its internal control over financial reporting and may identify material weaknesses in the future or otherwise fail to develop or maintain an effective system of internal controls;

● the volatility of the Company’s common stock and value of our public warrants;

● the other factors disclosed in this Quarterly Report on Form 10-Q and the Company’s other filings with the Securities and Exchange Commission (the “SEC”), in particular the risks described in “Part II, Item 1A” of this Quarterly Report and “Part I, Item 1A” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 16, 2023.

The forward-looking statements contained in this Quarterly Report on Form 10-Q are based on information available as of the date of this Quarterly Report on Form 10-Q and current expectations, forecasts and assumptions, and involve a number of judgments, risks and uncertainties. Accordingly, forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and should not be relied upon as representing the Company’s views as of any subsequent date. The Company does not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

SES AI Corporation

Notes to Condensed Consolidated Financial Statements

(Unaudited)

(Dollars in thousands, unless otherwise stated)

Note 1.  Nature of Business

Organization

SES AI Corporation and its consolidated subsidiaries (together the “Company” or “SES”), is engaged in the development of high-performance, Lithium-Metal (“Li-Metal”) rechargeable battery technologies for electric vehicles (“EVs”), electric vehicle take-off and landing (“eVTOL”) and other applications. We were founded in 2012, and our mission is to facilitate the widespread adoption of sustainable electric transportation, both on land and in air, by creating best-in-class, high energy density Li-Metal batteries centered around long-range performance and safety. Our third-party tested, differentiated battery technology has been designed to combine the high energy density of Li-Metal with the cost-effective, large-scale manufacturability of conventional Lithium-ion (“Li-ion”) batteries and will help to promote the transition from the global dependence on fossil fuel-based automotive vehicles to clean and efficient EVs. The Company’s headquarters are located in Woburn, Massachusetts with research and development facilities located there, in Shanghai, China, and in Chungju, South Korea. Principal operations have not yet commenced as of March 31, 2023, and the Company has not derived revenue from its principal business activities.

Note 2.  Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and are unaudited. These financial statements do not include all of the annual disclosures required by U.S. GAAP; accordingly, they should be read in conjunction with the audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 16, 2023 (the “Annual Report”). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the condensed consolidated financial statements for the interim periods presented. The results of operations for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the full year or any other future interim or annual periods. All intercompany balances and transactions have been eliminated in consolidation. As a result of the Business Combination completed on February 3, 2022, prior period share and per share amounts presented in the accompanying condensed consolidated financial statements and these related notes have been retroactively converted. The Company’s fiscal year ends on December 31.

During the three months ended March 31, 2023, there have been no significant changes to the Company’s significant accounting policies as disclosed in “Note 2 – Basis of Presentation and Summary of Significant Accounting Policies” of the Company’s above mentioned Annual Report, except as described below.

Reclassification of Prior Period Amounts

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. The Company reclassified the change in accrued compensation and the change in operating lease liabilities to the change in accrued expenses and other liabilities in the prior year’s statements of cash flows in the amount of $0.6 million and ($0.3) million for the three months ended March 31, 2022, respectively. There was no change to previously reported net cash used in operating activities.

Use of estimates

The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires management to make use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of commitments and contingencies, and the reported amounts of revenues, if any, and expenses. The Company bases its estimates on available historical experience and on various other factors that the Company believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from those estimates.

8

Significant estimates and assumptions include those related to the valuation of (i) certain equity awards, including common stock awards prior to the Business Combination, the Sponsor Earn-Out Shares, the Earn-Out Restricted Shares, and performance stock units, (ii) deferred tax assets and uncertain income tax positions, and (iii) and the measurement of operating lease liabilities. On an ongoing basis, the Company evaluates these judgments and estimates for reasonableness.

Investments

The Company has investments in marketable debt and marketable equity securities. Investments in marketable debt securities, which are comprised of U.S. treasury securities, are classified as available-for-sale and are recorded at fair value with any unrealized gains and losses included as a component of accumulated other comprehensive loss in total stockholders’ equity on the consolidated balance sheets until realized or until a determination is made that an other-than-temporary decline in market value has occurred. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, with such amortization and accretion reported within interest income, net in the consolidated statement of operations and comprehensive loss. Marketable debt security investments with a stated maturity date of less than one year are classified as short-term investments, while those with a stated maturity date of more than one year, and that are not expected to be used in current operations, are classified as long-term investments on the consolidated balance sheet, respectively. Investments in marketable equity securities with a readily determinable fair value, not accounted for under the equity method, are recorded at fair value with changes to fair value reported within other income (expense), net in the consolidated statements of operations and comprehensive loss.

Fair Value Measurements

Fair value is defined as an exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be either recorded or disclosed at fair value, the Company considers the principal or most advantageous market in which it would transact, and it also considers assumptions that market participants would use when pricing the asset or liability.

The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. GAAP establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1    Observable inputs such as quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2    Inputs other than the quoted prices in active markets that are observable either directly or indirectly.

Level 3    Unobservable inputs in which there are little or no market data and which require the Company to develop its own assumptions.

9

Certain of the Company’s financial instruments, including cash and cash equivalents, accounts payable, accrued expenses and other current liabilities are carried at cost, which approximates their fair value because of their short-term nature. The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis:

Note 7.  Government Grant

In December 2022, the Company was awarded a grant (the “Grant”) from certain government agencies. The incentives received under the Grant, which is in the form of cash, can be used for facilities related expenses and the purchase of property and equipment. The Company is required to adhere to the following conditions attached to the incentives, which include required minimum investments into specified spending categories and the creation of a minimum amount of permanent full-time jobs in a certain geographical location over the next five years. As of March 31, 2023, the Company had received, but not yet earned, 8.4 billion Korean won, which is equivalent to $6.4 million after translation, as disclosed as a noncurrent liability in the condensed consolidated balance sheet.

Note 8.  Sponsor Earn-Out Liability

On February 2, 2022, in connection with the Domestication, 6,900,000 of Ivanhoe’s Class B ordinary shares held by Ivanhoe Capital Sponsor LLC (the “Sponsor”) converted into an equal number of shares of duly authorized, validly issued, fully paid and nonassessable Class B common stock, par value $0.0001 per share (the “Class B Common Stock”), of the Company. At Closing, these 6,900,000 shares of Class B Common Stock converted into an equal number of shares of duly authorized, validly issued, fully paid and nonassessable Class A common stock par value $0.0001 per share (the “Class A Common Stock”, and together with the Class B Common Stock, “Common Stock”), of the Company (the “Sponsor Earn-Out Shares”). These Sponsor Earn-Out Shares are subject to certain transfer restrictions and forfeiture terms following the Closing, which will be released as follows:

● 20% were subject to transfer restrictions until the date that was 180 days after the Closing (“Tranche 1”);

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $12.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 2”);

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $14.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 3”);

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $16.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 4”); and

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $18.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 5”).

If there is a change in control of SES at a per share value of greater than $18.00, then 100% of the Sponsor Earn-Out Shares will be released from these transfer restrictions; however if the per share value is less than $18.00 upon a change in control, then the Sponsor Earn-Out Shares will be released pro rata based on the per share value of the change in control and the stock price thresholds for release specified above. Any Sponsor Earn-Out Shares not released will be forfeited and cancelled.

The Sponsor Earn-Out Shares in Tranche 1 were accounted for as equity instruments because they are legally owned by the Sponsor, cannot be forfeited and were subject only to transfer restrictions that lapsed 180 days after the Closing Date, which occurred on August 2, 2022. The Sponsor Earn-Out Shares in Tranches 2 through 5 represent the Sponsor Earn-Out Liability and are accounted for as a derivative liability because the earn-out triggering events that determine the number of Sponsor Earn-Out Shares to be earned back by the Sponsor include events that are not solely indexed to the shares of Class A common stock.

The Sponsor Earn-Out Liability is measured at its estimated fair value using Level 3 inputs in a Monte Carlo simulation valuation model. As of the three months ended March 31, 2023, the earn-out triggering events were not achieved for any of Tranche 2 through Tranche 5,

12

and as such the Company adjusted the carrying amount of the Sponsor Earn-out Liability to its estimated fair value of $10.4 million in the condensed consolidated balance sheet.

The following table provides a reconciliation of the beginning and ending balances for the Sponsor Earn-Out Liability:

		(in thousands)
Balance as of December 31, 2022	$	10,961
Additions during the period		—
Change in fair value		(569)
Balance as of March 31, 2023	$	10,392

Inherent in the valuation model are assumptions related to expected stock price volatility, risk-free interest rate, expected life, and dividend yield. The key inputs used in the Monte Carlo simulation model at their respective measurement dates were as follows:

		March 31, 2023		December 31, 2022
Contractual term (in years)		3.8		4.1
Risk free rate		3.76%		4.09%
Expected volatility		90.0%		85.0%
Expected dividends		0%		0%
Stock price	$	2.95	$	3.15

The stock price is based on the closing price of the Company’s Class A common stock as of the valuation date and simulated through the end of the earn-out period following Geometric Brownian Motion. The Company estimates the volatility of its common stock by using an average of historical volatilities of SES’s and select peer companies’ common stock that matches the expected remaining term of the awards. The risk-free interest rate is based on the yield curve for zero-coupon U.S. Treasury notes with maturities corresponding to the expected remaining life of the awards, which is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

Note 9.  Commitments and Contingencies

Commitments

Under the terms of one of the JDAs, the Company is committed to undertake certain research and development activities to the benefit of both itself and its OEM Partner which involves expenditures related to engineering efforts and purchases of related equipment. This JDA has an agreed-upon value of up to $50 million, of which the Company has spent $2.5 million as of March 31, 2023.

In December 2021, the Company amended the lease agreement on an office space in Woburn, Massachusetts. The amendment includes an obligation to pay monthly relinquishment charges (equal to the total rental obligation for the duration of the lease term), only if the new tenant does not pay monthly rental amount and lessor has provided a notice to collect the relinquishment charges from the Company. As of March 31, 2023, the Company assessed the probability of any liability to be incurred for relinquishment charges as remote.

Legal Contingencies

From time-to-time, the Company may be subject to claims arising in the ordinary course of business or become involved in litigation or other legal proceedings. While the outcome of such claims or other proceedings cannot be predicted with certainty, the Company’s management expects that any such liabilities, to the extent not provided for by insurance or otherwise, would not have a material effect on the Company’s financial condition, results of operations or cash flows.

Indemnifications

The Company enters into indemnification provisions under agreements with other companies in the ordinary course of business, including, but not limited to, partnerships, landlords, vendors, and contractors. Pursuant to these arrangements, the Company agrees to indemnify, defend, and hold harmless the indemnified party for certain losses suffered or incurred by the indemnified party as a result of the Company’s activities. The maximum potential amount of future payments the Company could be required to make under these agreements is not

13

determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification provisions. In addition, the Company indemnifies its officers, directors, and certain key employees against claims made with respect to matters that arise while they are serving in their respective capacities as such, subject to certain limitations set forth under applicable law, and applicable indemnification agreements. The Company maintains insurance, including commercial general liability insurance, product liability insurance, and directors and officers insurance to offset certain potential liabilities under these indemnification provisions. To date, there have been no claims under these indemnification provisions.

Note 10.  Stock-Based Compensation

The Company’s stock-based compensation included in its condensed consolidated statements of operations and comprehensive loss was as follows:

	Three Months Ended March 31,
(in thousands)	2023		2022
Research and development	$	1,847	$	554
General and administrative		4,615		2,632
Total stock-based compensation	$	6,462	$	3,186

The following table summarizes share-based compensation expense by award type:

	Three Months Ended March 31,

Performance Stock Units ("PSUs")		1,326		—
Restricted Stock Awards ("RSAs")		930		1,478
Stock options		110		115
Total	$	6,462	$	3,186

Note 11.   Income Taxes

The Company’s effective tax rate for the three months ended March 31, 2023 was (0.9)%, compared with 0% for the three months ended March 31, 2022. The difference between the provision for income taxes and the income tax determined by applying the statutory federal income tax rate of 21% principally results from income taxes on earnings from its foreign tax jurisdictions offset by losses generated in the U.S. where no benefit was recorded because the Company had fully reserved its deferred tax assets as of March 31, 2023 and December 31, 2022 and the recording of uncertain tax positions and interest expense.

As of March 31, 2023, there were $0.9 million in changes to the total amount of unrecognized tax benefits related to transfer pricing adjustments.

Note 12.  Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing net income (loss), as adjusted for changes in fair value recognized in earnings from equity contracts classified as liabilities, by the weighted average number of common shares outstanding and, when dilutive, common share equivalents from outstanding stock options and restricted stock units (using the treasury-stock method). The weighted-average number of common shares used in the computation of basic and diluted net income per share were as follows:

	Three Months Ended March 31,
(in thousands, except share and per share amounts)	2023		2022
Numerator:
Net loss attributable to common stockholders - basic	$	(16,226)	$	(27,033)
Denominator:
Weighted average shares of common stock outstanding - basic and diluted		313,422,442		219,180,317
Net loss per share attributable to common stockholders - basic and diluted	$	(0.05)	$	(0.12)

14

The number of common stock equivalents excluded from the computation of diluted net loss per share because either the effect would have been anti-dilutive, or the performance criteria related to such shares and awards had not been met, were as follows:

	As of March 31,
	2023		2022
Escrowed Earn-Out Shares		27,690,978		27,690,978
Options to purchase common stock		18,203,903		20,714,793
Public Warrants		9,199,947		9,199,947
Sponsor Earn-Out Shares		5,520,000		5,520,000
Private Warrants		5,013,333		5,013,333
Unvested RSUs		2,789,984		—
Unvested PSUs		2,116,942		—
Earn-Out Restricted Shares		1,929,140		2,299,889
Unvested RSAs		1,090,610		2,273,727
Total		73,554,837		72,712,667

Note 13.  Related-Party Transactions

As of March 31, 2023 and December 31, 2022, General Motors Company and its affiliates (“GM”) were considered a related party due to their board representation and the board member’s employment position at GM, as well as GM holding more than 5% of the fully diluted outstanding equity securities of SES.  See “Note 3 – Partnerships” for more details about our partnership with GM.

Factors that might cause or contribute to such forward-looking statements include, but are not limited to, those set forth in Part II, Item 1A of this Quarterly Report on Form 10-Q and in Item 1A. Risk Factors in the 2022 Annual Report. Unless the context otherwise requires, references in this section to “the Company,” “we,” “us” and “our” refer to the business and operations of SES Holdings Pte. Ltd. (“Old SES”) and its consolidated subsidiaries prior to the Business Combination and to SES AI Corporation and its consolidated subsidiaries following the Closing. References in this section to our future plans that indicate the timing of when we expect such plans to be completed by a certain year mean at any point during that year.

Overview

We are a pre-commercialization stage company engaged in the development and production of high-performance, Lithium-Metal (“Li-Metal”) rechargeable battery technologies for electric vehicles (“EVs”), electric vehicle take-off and landing (“eVTOL”) and other applications. Our third-party tested, differentiated battery technology has been designed to combine the high energy density of Li-Metal with the cost-effective, large-scale manufacturability of conventional Lithium-ion (“Li-ion”) batteries and will help to promote the transition from the global dependence on fossil fuel-based automotive vehicles to clean and efficient EVs.

Our mission is to facilitate the widespread adoption of sustainable electric transportation, both on land and in air, by creating best-in-class, high energy density Li-Metal batteries centered around long-range performance and safety. To assist in achieving this mission, we have partnered with leading global original equipment manufacturers (“OEMs”), General Motors (“GM”), Hyundai Motor Company (“Hyundai”), and Honda Motor Company, Ltd. (“Honda”), among other strategic partners, under joint development agreements (“JDAs”) to jointly develop and produce our Li-Metal battery cells and technology. We are currently working to transition from the development and production of A-Sample batteries to B-Sample batteries with specifications required by OEMs for their EVs. A-Sample batteries are functional prototypes developed for OEMs based on their technical specifications. These are in contrast with B-Sample batteries, which are A-sample batteries manufactured under much higher throughput and tested in actual vehicles, and C-Sample batteries, which would be fully functional, mature samples for mass production and tested for full drivability in actual vehicles.

We are also conducting research and development activities to further improve the performance, quality and cost of our battery technology by focusing on the following key areas, all of which we expect to help us achieve our commercialization goal, at our facilities in Woburn, Massachusetts in the United States, Shanghai, China, and Chungju, South Korea.

● Scale-up: Our design is further being customized with and validated by several OEMs. Based on our collaborations with OEMs, we believe that a roughly 100 Ah cell-size manufactured at GWh scale (five to seven cells-per-minute) is needed to achieve commercialization in EVs at a large, global scale. We are developing processes and equipment to scale up the manufacturing of our current cell design from three to nine Ah capacity to 50 Ah and 100 Ah.

● Module and Pack Design: Li-Metal cells must be integrated into modules and packs as part of their integration into vehicles. Our active development efforts are focused on the integration of our Li-Metal cells in modules to enable our Li-Metal cells to perform as intended once they are integrated into modules and vehicles.

● Advanced Artificial Intelligence (“AI”) Software and Battery Management Systems (“BMS”): Software is critical to ongoing monitoring of battery health and safety. We continue to develop advanced AI algorithms to diagnose battery cell-related health issues, develop advanced control algorithms and charging methods to enhance cycle life and safety, and port such software on to a BMS that could be integrated into a battery pack.

16

● Advanced Materials and Coatings: We continue to research and develop advanced electrolyte and anodes to further improve cycle life and safety. In addition, we continue to develop novel methods of laminating or depositing lithium metal onto current collector that can be deployed at commercial GWh scale.

● Cathode Materials and Design: We develop our Li-Metal cells for a variety of different cathode materials, cathode design and cathode processing methods that can provide ultra-high energy density and/or significant cost-reduction.

● Li-Metal Recycling: Along with other battery components that are already being recycled today, Li-Metal foil will also need to be recycled in the future. We continue to explore methods of recycling that are productive and cost-effective.

During the three months ended March 31, 2023, we continued to make improvements to our three A-sample production lines, one in China and two in South Korea, which are producing and testing large 50 Ah and 100 Ah Li-Metal cells. In addition, we entered into a new leased facility in South Korea.

Outlook

We plan to transition from A-sample to B-sample battery development and production in the second half of 2023. We expect this to lead to a significant increase in our headcount and footprint of our research and pre-production pilot facilities as we expand our existing facilities and entering into new facilities. Additionally, we also plan to build a fourth production line, which will be a major milestone for the automotive commercialization of our Li-Metal cells. The buildout of this fourth production line is expected to be fully operational and ready-to-use in the first half of 2024.

After B-Sample, we plan to transition to C-Sample in 2024, which we then expect to enable us to commence commercial production of our technology in 2025. As the joint development of Li-Metal batteries with our OEM partners continues to progress, we also expect to launch future research facilities and, eventually, commercial production manufacturing facilities in the United States. We expect that this will significantly increase our materials consumption and the rate of cash utilization over time.

Finally, we expect to explore opportunities for partial vertical integration, both upstream and downstream, to ensure scalability of our battery cells and battery technology. Upstream, we intend to explore integrating vendors of key materials of our cells and providers of key equipment and engineering capabilities, such as cell assembly, anode processing, chemical processing and safety testing. Downstream, we plan to explore integrating providers of key engineering capabilities, such as battery state-of-health monitoring software, charging optimization software, battery module development and recycling.

Results of Operations

Factors Affecting Operating Results

As a pre-commercialization company, we have not generated any revenue from sales to customers to date through our one operating segment and have spent $11.7 million and $12.7 million on research and development activities during the three months ended March 31, 2023 and 2022, respectively, which is prior to credits received by our OEM partners under the JDAs. As a result, we have incurred net losses of $16.2 million and $27.0 million for the three months ended March 31, 2023 and 2022, respectively. Our historical results may not be indicative of our future results for reasons that may be difficult to anticipate and our ability to generate revenue in the future that is sufficient enough to achieve profitability will depend largely on the successful development of our products. Accordingly, the drivers of our future financial results, as well as the components of such results, may not be comparable to our historical results of operations.

The following table sets forth our historical operating results for the periods indicated:

	Three Months Ended March 31,				$		%
(in thousands)	2023		2022		Change		Change
Research and development	$	8,489	$	4,067	$	4,422	109	%
General and administrative		13,123		15,130		(2,007)	(13)	%
Total operating expenses	$	21,612	$	19,197	$	2,415	13	%

Research and Development

Research and development expenses consist primarily of costs incurred for salaries and personnel-related expenses, including bonus and stock-based compensation expense, for scientists, experienced engineers and technicians, expenses for materials and supplies used in product research and development, process engineering efforts and testing, as well as payments to consultants, depreciation, and allocated

17

facilities and information technology costs. Additionally, payments received from the JDA agreements are treated as credits to research and development expenses.

Research and development expenses for the three months ended March 31, 2023 increased $4.4 million, or 109%, to $8.5 million, compared with $4.1 million for the three months ended March 31, 2022. The increase primarily resulted from a $2.3 million increase in personnel costs mainly attributable to our growth in headcount in support of our ongoing research and development efforts for battery cell development, which included $1.2 million of stock-based compensation expense that primarily relates to restricted earnout shares issued as part of the Business Combination transaction in February 2022 and RSUs and PSUs issued in April 2022. Further, there was a $1.3 million increase in facility costs due to utilities and depreciation expenses, a  $1.1 million increase in expenses for lab consumables and material supplies, and a $1.0 million increase in software development costs related to our advanced AI software and BMS. The remainder of the increase was attributable to immaterial other spend. These increases were partly offset by $1.5 million of increased credits to research and development expenses, which are amounts invoiced pursuant to the JDAs. Lastly, there was a $6.8 million decrease in non-recurring facility set-up expenditures in the prior year period, which were offset through reimbursements pursuant to a JDA mentioned above.

General and Administrative

General and administrative expenses consist primarily of costs incurred for salaries and personnel-related expenses, including bonus and stock-based compensation expense, for our finance, legal and human resource functions, expenses for director and officer insurance, outside contractor and professional service fees, audit and compliance expenses, legal, patent related costs, accounting and other advisory services, as well as allocated facilities and information technology costs including depreciation. Upon commencement of commercial operations, we also expect to incur customer and sales support and advertising costs.

General and administrative expenses for the three months ended March 31, 2023 decreased $2.0 million, or 13%, to $13.1 million, compared with $15.1 million for the three months ended March 31, 2022. This decrease primarily resulted from a $4.6 million decrease in transaction costs incurred as a result of the Business Combination during the first quarter of 2022 and a $0.4 million decrease in fees related to marketing and public relations for the Company. These decreases were partially offset by a $2.6 million increase in personnel costs mainly attributable to our growth in headcount to support our operations as a public company, which included $2.0 million of stock-based compensation expense that primarily relates to restricted earnout shares issued as part of the Business Combination transaction in February 2022 and RSUs and PSUs issued in April 2022. Further, there was a $0.7 million increase in professional fees and outside services primarily associated with external consulting, legal, and audit fees.

Non-Operating Items

Interest Income, Net

Interest income primarily consists of interest earned on our cash and cash equivalents and marketable debt securities, which are primarily invested in money market funds and U.S. treasury securities, and accretion income from the U.S. treasury securities.

During the three months ended March 31, 2023, we had interest income of $4.1 million compared with an immaterial amount for the three months ended March 31, 2022. The $4.1 million increase was primarily due to a change in our investment strategy during the fourth quarter of 2022, which resulted in an increased amount of our cash being invested in higher yielding U.S. treasury securities and due to higher interest rates in the current period compared to the same period last year.

Change of Fair Value of Earn-Out Liability, Net

During the three months ended March 31, 2023, we incurred a gain of $0.6 million associated with the change in fair value of the Sponsor Earn-Out Liability compared with a loss of $7.7 million for the three months ended March 31, 2022. With the fair value of the Sponsor Earn-Out Liability tied to the Company’s stock price, continued volatility in the stock price could result in further gains or losses resulting from the change in fair value. Refer to “Note 8 – Sponsor Earn-Out Liability” to the condensed consolidated financial statements for additional information.

Other (Expense) Income, Net

During the three months ended March 31, 2023, we had other income of $0.8 million, compared with other expense of $0.2 million for the three months ended March 31, 2022. The $1.0 million increase in other income was primarily the result of a gain on equity investments and unrealized and realized foreign currency gains due to the strengthening of the U.S. dollar compared with the Chinese renminbi (RMB) and South Korean won (KRW).

18

Provision for Income Taxes

The provision for income taxes for the three months ended March 31, 2023 increased to $0.1 million compared to the three months ended March 31, 2022 mainly due to an increase in pre-tax income in China and South Korea.

Liquidity and Capital Resources

As of March 31, 2023, we had total cash and cash equivalents of $48.0 million and investments in marketable debt and equity securities of $324.7 million. As a pre-commercialization stage research and development company, the net operating losses we have incurred since inception are consistent with our strategy and budget.

We expect to continue to sustain substantial operating expenses, due to the capital-intensive nature of our business, without generating sufficient revenues to cover expenditures for a number of years. To date, we have funded our operations through a combination of our cash on hand, which primarily originated from proceeds from the Business Combination and PIPE Financing and from funding received through the sales of our redeemable convertible preferred stock, and proceeds from our JDAs with our OEM partners. These funds are expected to finance our principal sources of liquidity and ongoing costs, such as research and development relating to our Li-Metal batteries and the construction of additional manufacturing facilities. In the future, if we are not able to fund our operations from cash flows generated from anticipated product sales, we expect that we will need to raise additional funds through a variety of possible methods, including, but not limited to, entry into joint ventures or other strategic arrangements, issuance of equity, equity-related or debt securities or through obtaining credit from financial institutions, as well as anticipated future revenue from product sales.

We believe that our cash on hand and marketable securities will be sufficient to meet our working capital and capital expenditure requirements for a period of at least 12 months from the date of this Report, and also sufficient to fund us to commercialization. However, additional funding may be required for a variety of reasons, including opportunities to build an integrated supply chain in the United States and delays in expected development of our Li-Metal battery cells. Our ability to successfully develop our products, commence commercial operations and expand our business will depend on many factors, including our working capital needs, the availability of equity and/or debt financing and, over time, our ability to generate positive cash flows from operations.

Summary of Cash Flows

The following table provides a summary of our cash flow data for the periods indicated:

	Three Months Ended March 31,
(in thousands)	2023		2022
Cash (used in) provided by:
Operating activities	$	(15,393)	$	(14,815)
Investing activities		(43,093)		(2,659)
Financing activities		13		282,944
Effect of exchange rate changes on cash		(198)		109
Net (decrease) increase in cash, cash equivalents and restricted cash	$	(58,671)	$	265,579

Operating Activities

Our cash flows used in operating activities to date have been primarily comprised of research and development and general and administrative activities as discussed above. As we continue to ramp up hiring for research and development headcount to accelerate our engineering efforts, we expect our cash used in operating activities to increase significantly before we start to generate any material cash inflows from our operations.

Net cash used in operating activities of $15.4 million for the three months ended March 31, 2023 was primarily attributable to net loss of $16.2 million as adjusted for stock-based compensation expense of $6.5 million, accretion income from marketable securities of $2.9 million, depreciation and amortization of $1.1 million, a gain on change in fair value of Sponsor Earn-Out Liability of $0.6 million and a $2.5 million working capital outflow. The working capital outflow was primarily driven by a $2.6 million increase in prepaids and other assets primarily due to the renewal of the insurance policy to cover potential liabilities under our indemnification obligations to our directors and certain officers, a $0.4 million increase in receivable from related party driven by activity from the associated JDA, and a $0.1 million increase in inventory due to materials purchases. The working capital outflow was partially offset by a $0.6 million increase in accrued expenses and other liabilities primarily due to increases in accrued bonus, accrued taxes, and professional fees associated with audit fees.

19

Net cash used in operating activities of $14.8 million for the three months ended March 31, 2022 was primarily attributable to net loss of $27.0 million as adjusted for a non-cash charge attributable to change in fair value of Sponsor Earn-Out Liability of $7.7 million, stock-based compensation expense of $3.2 million, and depreciation and amortization expense of $0.4 million, partially offset by a working capital inflow of $0.9 million. The working capital inflow was primarily driven by a $5.4 million increase in accounts payable, including $4.6 million for fees incurred in relation to the Business Combination and the PIPE Financing, a $1.6 million increase in accrued expenses and other liabilities primarily attributable to advance payments received from our OEM partners and accrued compensation, and a $0.4 million decrease in receivables from a related party mainly attributable to JDA activity. The working capital inflow was partially offset by a $6.5 million increase in prepaid expenses and other current assets primarily due to the increase in insurance costs to cover potential liabilities under our indemnification obligations to our directors and certain officers.

Investing Activities

Net cash used in investing activities was $43.1 million for the three months ended March 31, 2023 compared to net cash used in investing activities of $2.7 million for the three months ended March 31, 2022.

Purchases and Maturities of Investments – Net purchases of investments in marketable debt and equity securities were $37.1 million for the three months ended March 31, 2023 compared to no purchases of investments or maturities for the three months ended March 31, 2022.

Capital Spending – Capital expenditures were $6.0 million and $2.5 million for the three months ended March 31, 2023 and 2022, respectively, and primarily related to purchases of lab machinery and equipment, lab tools and instruments related to our facilities. We expect capital expenditures for the rest of 2023 to increase compared with the corresponding period in 2022 as we continue to invest in the build out of our manufacturing pre-production facilities.

Financing Activities

Net cash provided by financing activities was immaterial for the three months ended March 31, 2023.

Net cash provided by financing activities of $282.9 million for the three months ended March 31, 2022 primarily related to proceeds received from the Business Combination and PIPE Financing, net of transaction costs.

Contractual Obligations and Commitments

The following table summarizes our material contractual obligations for cash expenditures as of March 31, 2023, and the periods in which these obligations are due:

	Short Term		Long Term		Total
Purchase obligations(1)	$	31,322	$	25,529	$	56,851
Operating lease obligations(2)		2,741		11,561		14,302
Total	$	34,063	$	37,090	$	71,153

⁽¹⁾ Purchase obligations include commitments for the purchase of lab supplies and equipment as well as committed spend related to a JDA. These commitments are derived from purchase orders, supplier contracts and open orders based on projected demand information.

⁽²⁾ Operating lease obligations represent the fixed lease payments for the noncancelable lease term, fixed lease payments for optional renewal periods where the Company is reasonably certain the renewal option will be exercised, and variable lease payments that depend on an underlying index or rate in effect at lease commencement.

Off-Balance Sheet Arrangements

As of March 31, 2023, we had a letter of credit issued by a financial institution totaling $0.6 million. The letter of credit relates to deposits the Company is required to maintain under one of its operating lease agreements. We have restricted cash that serves as collateral for this outstanding letter of credit that is included in other assets on our condensed consolidated balance sheet. No amounts have been drawn under the letter of credit.

Recent Accounting Pronouncements

See “Note 2 – Basis of Presentation” of our accompanying unaudited condensed consolidated financial statements for the three months ended March 31, 2023 included in this Quarterly Report on Form 10-Q for more information about recent accounting pronouncements, the timing of their adoption, and their potential impact on our financial condition, results of operations and cash flows.

Critical Accounting Estimates and Judgments

Our financial statements have been prepared in accordance with U.S. GAAP. In the preparation of these unaudited condensed consolidated financial statements, we are required to use judgment in making estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the unaudited condensed financial statements, as well as the reported expenses incurred during the reporting periods.

There have been no significant changes to our critical accounting policies or in the underlying accounting assumptions and estimates used in such policies from those disclosed in our annual consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2022.

Other Information

The Company’s website is www.ses.ai. Information contained on the Company’s website is not part of this report. Information that we furnish to or file with the SEC, including the Company’s annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to, or exhibits included in, these reports are made available for download, free of charge, through the Company’s website as soon as reasonably practicable. The Company’s SEC filings, including exhibits filed therewith, are also available directly on the SEC’s website at www.sec.gov.

The Company may use its website as a distribution channel of material company information.  Financial and other important information regarding the Company is routinely posted on and accessible through the Company’s website at www.ses.ai. Accordingly, investors should monitor this channel, in addition to following the Company’s press releases, SEC filings and public conference calls and webcasts. The contents of our website are not, however, a part of this report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to a variety of markets and other risks including the effects of change in interest rates, inflation and foreign currency translation and transaction risks as well as risks to the availability of funding sources, hazard events and specific asset risks.

Interest Rate Risk

The market interest risk in our financial instruments and our financial positions represents the potential loss arising from adverse changes in interest rates. As of March 31, 2023, we had cash, cash equivalents, and restricted cash of $49.3 million, primarily consisting of interest-bearing money market funds, and marketable debt securities of $323.5 million, consisting of investments in U.S treasuries, respectively. A 100 basis point increase in the general level of U.S. interest rates relative to interest rates as of March 31, 2023 would decrease the fair value of our marketable debt securities by approximately $1.8 million. This estimate is based on a sensitivity model that measures market value changes when changes in interest rates occur. Such a decrease in fair value would only be realized if we sold the investments prior to maturity.

Foreign Currency Risk

The functional currency of all our entities and all its subsidiaries is the U.S. dollar, except for our subsidiaries in China and South Korea, which has Chinese renminbi (RMB) and South Korean won (KRW), respectively, as its functional currency, reflecting its principal operating economic environment. We expect to be exposed to both currency transaction remeasurement and translation risk. Net realized and unrealized gains (losses) from foreign currency transactions are included in other expense, net in the consolidated statement of operations and comprehensive loss and amounted to a gain of $0.1 million for the three months ended March 31, 2023. This foreign transaction gain was primarily due to the strengthening of the U.S. dollar to the Chinese renminbi (RMB) and South Korean won (KRW). We have not hedged such exposure, although we may do so in the future.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures 

Under the supervision and with the participation of our management, including our chief executive officer (“CEO”) and chief financial officer (“CFO”), we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2023, as such term is defined in Rules 13a-15(e) and 15d-15(e) under Securities Exchange Act of 1934, as amended (the “Exchange Act”). Disclosure controls and procedures include, without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act 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 our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. Based on this evaluation, our principal executive officer and principal financial officer have concluded that as of March 31, 2023, our disclosure controls and procedures were not effective due to material weaknesses in our internal control over financial reporting, as discussed in more detail below.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. 

Notwithstanding the identified material weaknesses, management, with the participation of the principal executive officer and principal financial officer, believes the condensed consolidated financial information included in this Quarterly Report on Form 10-Q fairly represent in all material respects our financial condition, results of operations and cash flows at and for the periods presented in accordance with U.S. GAAP.

Material Weaknesses

We previously identified material weaknesses, as disclosed in our 2022 Annual Report.

Certain components of the Company’s control environment were ineffective as the Company did not have a sufficient complement of resources with assigned responsibility and accountability for the design, operation and documentation of internal control over financial reporting.  This created deficiencies in the Company’s risk assessment process that led to ineffective information and communication activities as the controls necessary to ensure the reliability of information used in financial reporting and communicate relevant information about roles and responsibilities for internal control over financial reporting were ineffective. As a result, process-level control activities were not designed, implemented or operated effectively in the substantial majority of our processes.

Changes in Internal Control over Financial Reporting 

Other than the actions taken as described in “Management’s Remediation Initiatives” below to improve the Company’s internal control over financial reporting, there have been no changes in our internal control over financial reporting during the most recent fiscal quarter that materially affected, or which are reasonably likely to materially affect, our internal control over financial reporting. 

Management’s Remediation Initiatives 

We have taken the following steps towards remediation of the identified material weaknesses and to enhance our internal control over financial reporting:

● We are developing a detailed remediation plan, with appropriate executive sponsorship and with the assistance of third-party specialists, to specifically address the material weaknesses.

● We have hired, and will continue to hire, additional certified public accountants (including those with public company experience) who have the appropriate level of expertise in the areas of accounting, financial reporting, and internal controls commensurate with the volume and complexity of our reporting requirements. We will continue utilizing third-party consultants to supplement our internal resources to perform design assessments and execute key controls related to various financial reporting processes, as needed.

● We plan to design and implement a comprehensive and continuous risk assessment process to identify and assess risks of material misstatement and ensure that the impacted financial reporting processes and related internal controls are properly designed and in place to respond to those risks in our financial reporting.

22

● We plan to enhance the design of existing control activities and implement additional process-level control activities and ensure they are operating effectively.

● We plan to design and implement additional information and communications controls to ensure use of and obtain relevant and quality information to allow operation of effective control activities, including internal and external communication.

● We improved our capabilities to identify, research, and prepare supporting documentation for technical accounting issues. 

● We have enhanced our risk assessment process, and will continue to make it a more comprehensive and continuous process, to identify and assess risks of material misstatements and ensure that the related internal controls are properly designed and in place to respond to those risks.

● We plan to implement new IT applications which will automate some of the manual financial reporting processes.

We have expended, and will continue to expend, a substantial amount of effort and resources for the remediation and improvement of our internal control over financial reporting. We will continue to work on improvements to our internal controls during 2023 as we assess and evaluate the controls intended to remediate the material weaknesses. Until these weaknesses are remediated, we plan to continue to perform additional analyses and other procedures to ensure that our consolidated financial statements are prepared in accordance with GAAP.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be subject to claims arising in the ordinary course of business or become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. 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

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors disclosed in “Part I, Item 1A” of our Annual Report on Form 10-K for the year ended December 31, 2022, and the other reports that we have filed with the SEC. Any of the risks discussed in such reports, as well as additional risks and uncertainties not currently known to us or that we currently deem immaterial, could materially and adversely affect our results of operations, financial condition or prospects. During the period covered by this Quarterly Report on Form 10-Q, there have been no material changes in our risk factors as previously disclosed, except the following:

Recent events affecting the financial services industry could have an adverse impact on our business and financial condition.

The recent closures of Silicon Valley Bank, Signature Bank and Silvergate Capital Corporation, as well as acquisitions of Credit Suisse and First Republic Bank at regulators’ behest, have created bank-specific and broader financial institution liquidity risks and concerns. While we did not have any material deposits at any of these institutions, uncertainty remains over liquidity concerns in the financial services industry and potential impacts on the broader global economy, and our business, our suppliers, and/or the EV industry as a whole may be adversely impacted in ways that we cannot predict at this time.

If other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash and cash equivalents may be threatened. In addition, if any of our suppliers, OEMs or other parties with whom we conduct business are unable to access funds, such parties’ ability to pay or perform their obligations to us or to enter into new commercial arrangements requiring additional payments to us or additional funding could be adversely affected. Moreover, sufficient external financing may not be available to us on a timely basis, on commercially reasonable terms to us, or at all. Any of these events could adversely affect our business and financial condition.

Exhibit 10.2

Via Electronic Mail

jban@ses.ai

Dear Joanne:

This letter sets forth the agreement (“Agreement”) between SES AI Corporation (the “Company”), and you (“Advisor”), effective as of July 1, 2022 (the “Effective Date”), with respect to the performance of certain advisory services by Advisor as an independent contractor.

WHEREAS, the Company desires to engage Advisor with respect to the performance of certain advisory services by Advisor as an independent contractor as of the Effective Date.

NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein, the Company and Advisor agree as follows:

1. Advisory Services/Place of Performance.  The Company hereby engages Advisor as an independent contractor commencing on the Effective Date and continuing through and until terminated by the Company in accordance with the terms of this Agreement (the “Advisory Period”).  The advisory services to be provided by Advisor to the Company shall include such advice and assistance to the Company from time to time as further described on Schedule A attached hereto or as otherwise mutually agreed to by the parties (collectively, “Advisory Services”).

The Company shall not provide any training for Advisor, nor shall the Company provide Advisor with any office or other working space or facilities, tools, supplies, materials or equipment.  If the nature of the Advisory Services provided by Advisor requires that the services be performed at the Company’s premises, however, then the Company will provide Advisor such temporary working space and facilities as may be reasonably necessary but the Company will not integrate Advisor into its business operations.  The Company will not control and will have no right to control the exact manner, precise means or exact method by which Advisor performs the Advisory Services.  However, the Company will have the right to exercise general supervision over the results to be derived from the Advisory Services and the date(s) by which such Advisory Services will be completed, and will determine whether such Advisory Services were satisfactory to the Company.  

2. Services Fee/Expenses.  As full and complete payment for the Advisory Services (and the rights granted) hereunder:

a.Advisor will be paid a services fee of US$8,000 for each of July 2022 and August 2022 (the “Services Fee”).  Advisor will bill the Services Fee to the Company by invoice following the end of each calendar month.  The Company will pay each invoice in full within 30 days after receipt, unless the Company disputes such invoice.

b.Notwithstanding the cessation of employment of the Advisor as Chief Legal & Corporate Officer of the Company on June 30, 2022, all awards of stock options of the Company which had been made to the Advisor as at the Effective Date (the “Equity Awards”) shall continue to vest and be exercisable in accordance with the terms of the respective awards while this Agreement remains effective. The Company acknowledges that the advisory services contemplated hereby constitute the Advisor’s continued “providing services” to the Company in accordance with Section 9 of the SES Holdings Pte Ltd 2021 Share Incentive Plan, and as such, notwithstanding the Advisor’s cessation of employment with the Company, the Advisor will not have incurred a "termination" or “termination of service” for purposes of the SES Holdings Pte Ltd 2021 Share Incentive Plan while this Agreement remains effective.

The Company will issue Advisor an Internal Revenue Service Form 1099 with respect to the payment of the Services Fees, to the extent required by applicable law.  In addition, the Company will reimburse Advisor for any reasonable and pre-approved out-of-pocket expenses to third parties incurred in connection with the Advisory Services, including expenses for travel required by the Company.  Reimbursable expenses shall not include any expenses related to office or other working space or facilities, tools, supplies, materials or equipment.

3. Forfeiture of RSUs/PSUs. Advisor hereby agrees and consents to the waiver and forfeiture of any rights to vesting of, and any rights to delivery and settlement of common stock of the Company underlying (i) the 226,463 restricted stock units granted to Advisor on April 18, 2022 pursuant to a Restricted Stock Unit Award Agreement with the Company under the SES AI Corporation 2021 Incentive Award Plan (the “April 2022 RSUs”) and (ii) the 226,463 performance-vesting restricted stock units granted to Advisor on April 18, 2022 pursuant to a Performance Stock Unit Award Agreement with the Company under the SES AI Corporation 2021 Incentive Award Plan (the “April 2022 PSUs”, and together with the April 2022 RSUs, the “April 2022 Equity Grants”) following the cessation of Advisor’s employment with the Company. Advisor acknowledges and agrees that the April 2022 Equity Grants shall be forfeited, terminated and cancelled following Advisor’s cessation of employment with the Company and that no portion of the April 2022 Equity Grants which has not become vested as of the Effective Date shall thereafter become vested. Advisor hereby agrees and covenants to cooperate in good faith and to take all actions and do all things necessary to effectuate the waiver and forfeiture of the April 2022 Equity Grants contemplated by this Section 3, including signing any necessary agreements, certificates or documents.

4. Independent Contractor.  Advisor is not engaged by the Company on a full-time or exclusive basis. Advisor and the Company intend and agree that Advisor is an independent contractor and that nothing in this Agreement will be interpreted or construed as creating or establishing the relationship of employer and employee, agency, partnership, or joint venture between the Company and Advisor.

8. Covenants, Representations and Warranties; Compliance with Laws.  Advisor covenants, represents and warrants that their performance of the Advisory Services does not and will not violate any applicable law, rule, regulation, contracts with third-parties or rights in any patent, trademark, copyright, trade secret, domain name, know-how or other intellectual property right.  Advisor further warrants that Advisor is the lawful owner or licensee of any software programs or other materials used by Advisor in the performance of the Advisory Services except those made available to Advisor by the Company for use hereunder and that Advisor has all rights necessary to convey to the Company the unencumbered ownership of any deliverables. In addition, Advisor agrees to abide by all laws, rules and regulations applicable to the Company, as well as any Company policies and procedures, rules that are applicable to independent contractors.

9. Indemnification.  Advisor agrees to indemnify and hold harmless the Company and its affiliates and its and their respective owners, officers, directors, employees and agents from and against any and all claims, liabilities and/or expenses (including, without limitation, court costs and reasonable attorneys’ fees) resulting from, arising out of, or relating to the Advisory Services or any breach of the covenants, representations or warranties made by Advisor in Section 8 above.

10. Non-Compete. Advisor agrees and acknowledges that for the duration of this Agreement, Advisor shall not accept employment with another company, business entity or individual whose business, products or operations are in any respect competitive with the actual or anticipated business of the Company, as determined by the Company in its sole discretion. Advisor acknowledges that the Company’s market for its existing and/or anticipated products is

worldwide, and that potential competitors for the Company’s existing and anticipated products and services are located worldwide. Advisor further agrees and acknowledges that this Agreement will terminate immediately upon Advisor accepting an offer of employment with company, business entity or individual whose business, products or operations are in any respect competitive with the actual or anticipated business of the Company, as determined by the Company in its sole discretion.

11. Notification of Subsequent Employer. Advisor hereby agrees that prior to accepting employment with any other company, individual or business entity during any period during which the Advisor remains subject to any of the covenants set forth in Section 10, the Advisor shall notify the Company of Advisor’s intention to accept such employment by written notice provided at least five (5) business days in advance of the proposed start date of such employment.

12. Term and Termination; Survival.  The initial term of this Agreement is twelve (12) months beginning on the Effective Date. The term may be extended for subsequent additional twelve (12) month terms by mutual agreement of the parties hereto. Advisor understands and acknowledges that the Company will evaluate the quality and value of the advisory services provided by Advisor hereunder in considering whether to extend this Agreement.  

This Agreement may be terminated by the Company at any time with the provision of one (1) month’s prior written notice. The provisions of Sections 7, 8, 9 and 12 of this Agreement shall survive and shall continue to be binding upon the Advisor notwithstanding the termination or expiration of the Advisory Services for any reason whatsoever.

13. Export Control.  Advisor understands and acknowledges that in performing this Agreement, Advisor may gain access to information, technology or items that are subject to U.S. Government regulations including, but not limited to, the Export Administration Regulations (15 CFR § 730-774) (“EAR”) as administered by the U.S. Department of Commerce, Bureau of Industry and Security.  Advisor represents that they are authorized under the EAR to receive items, including technology, classified as Export Control Classification Numbers (“ECCN”) 3A001.e.1.b and/or 3E001, and maintains policies and procedures reasonably designed to ensure compliance with the EAR, as well as Export Controls, Sanctions and Anti-Corruption Laws. Advisor understands and acknowledges their obligation to control the flow of such information, technology or items, in compliance with such regulations and obtain all required authorizations or licenses.  Advisor certifies that it shall not knowingly export or re-export information, technology or items received from the other party without first obtaining all required government authorizations or licenses.  

14. No Assignment by Advisor; Successors and Assigns.  The Advisory Services are of a unique and specialized nature, to be rendered personally by Advisor in reliance upon Advisor’s unique experience, knowledge and skills.  Advisor therefore may not assign, transfer, or subcontract this Agreement or any of Advisor’s obligations hereunder without the prior written consent of the Company (and any purported assignment, transfer or subcontracting of this Agreement in violation of the foregoing shall be null and void).  Except for the prohibition on assignment contained in this paragraph, this Agreement shall be binding upon and inure to the benefit of the parties hereto and the successors and assigns of the Company and Advisor.

15. No Conflicts. Advisor represents that Advisor’s compliance with the terms of this Agreement and provision of the Services will not violate any duty which Advisor may have to any other person or entity (such as a present or former employer), and Advisor agrees that Advisor will not do anything in the performance of the Services that would violate any such duty. In addition, Advisor agrees that, during the term of this Agreement, Advisor shall promptly notify the Company in writing of any direct competitor of the Company which Advisor is also performing services. It is understood that in such event, the Company will review whether Advisor’s activities are consistent with Advisor remaining as an advisor of the Company.

16. Headings; Severability; Counterparts.  The use of headings in this Advisory Agreement are for convenience only and shall not be deemed to control or affect the meaning or construction of any provision hereunder.  If any portion of this Agreement is declared illegal or unenforceable by any court of competent jurisdiction and cannot be modified to be enforceable (with such modification as shall be necessary to make it enforceable to the fullest extent permissible under law), such portion shall immediately become null and void leaving the remainder of this Agreement in full force and effect. This Agreement may be executed in counterparts, each of which will be deemed an original, but all

of which will be deemed one and the same instrument.  Any facsimile or pdf copy of any party’s executed counterpart of this Agreement will be deemed to be an executed original thereof.

17. Irreparable Harm.  In the event of a breach (or threatened breach) of Sections 6, 7 and 8 by Advisor, Advisor acknowledges that the Company would have no adequate remedy at law and would be irreparably harmed and therefore the Company will be entitled to injunctive relief (without the necessity of proving actual damages or the posting of a bond or other security), both preliminary and permanent, enjoining such breach (or threatened breach).  Such remedies will be in addition to all other remedies available at law or in equity including the Company’s right to receive from Advisor any and all damages sustained as a result of Advisor’s breach.

18. Entire Agreement; No Modification; Governing Law.  This Agreement constitutes the entire agreement between Advisor and the Company regarding the subject matter hereof and supersedes any prior agreements or understandings regarding the Advisory Services, including without limitation, the Prior Agreements.  Advisor acknowledges and agrees that no promises or representations, oral or written, have been made regarding the subject matter hereof other than those expressly stated herein, and that Advisor has not relied on any other promises or representations in signing this Agreement.  This Agreement may be modified only by a document signed by the parties and referring explicitly hereto.  The Company’s and Advisor’s failure to insist upon strict compliance with any term of this Advisory Agreement shall not be deemed a waiver of such term or any other terms at that time or at any other time, unless it is in writing and signed by the party to be charged.  This Agreement is governed by and construed in accordance with the laws of New York, without regard to its conflicts of laws principles.

Note 1.  Nature of Business

Organization

SES AI Corporation and its consolidated subsidiaries (together the “Company” or “SES”), is engaged in the development of high-performance, Lithium-Metal (“Li-Metal”) rechargeable battery technologies for electric vehicles (“EVs”), electric vehicle take-off and landing (“eVTOL”) and other applications. We were founded in 2012, and our mission is to facilitate the widespread adoption of sustainable electric transportation, both on land and in air, by creating best-in-class, high energy density Li-Metal batteries centered around long-range performance and safety. Our third-party tested, differentiated battery technology has been designed to combine the high energy density of Li-Metal with the cost-effective, large-scale manufacturability of conventional Lithium-ion (“Li-ion”) batteries and will help to promote the transition from the global dependence on fossil fuel-based automotive vehicles to clean and efficient EVs. The Company’s headquarters are located in Woburn, Massachusetts with research and development facilities located there, in Shanghai, China, and in Chungju, South Korea.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Note 2.  Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and are unaudited. These financial statements do not include all of the annual disclosures required by U.S. GAAP; accordingly, they should be read in conjunction with the audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 16, 2023 (the “Annual Report”). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the condensed consolidated financial statements for the interim periods presented. The results of operations for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the full year or any other future interim or annual periods. All intercompany balances and transactions have been eliminated in consolidation. As a result of the Business Combination completed on February 3, 2022, prior period share and per share amounts presented in the accompanying condensed consolidated financial statements and these related notes have been retroactively converted. The Company’s fiscal year ends on December 31.

During the three months ended March 31, 2023, there have been no significant changes to the Company’s significant accounting policies as disclosed in “Note 2 – Basis of Presentation and Summary of Significant Accounting Policies” of the Company’s above mentioned Annual Report, except as described below.

Reclassification of Prior Period Amounts

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. The Company reclassified the change in accrued compensation and the change in operating lease liabilities to the change in accrued expenses and other liabilities in the prior year’s statements of cash flows in the amount of $0.6 million and ($0.3) million for the three months ended March 31, 2022, respectively. There was no change to previously reported net cash used in operating activities.

Use of estimates

The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires management to make use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of commitments and contingencies, and the reported amounts of revenues, if any, and expenses. The Company bases its estimates on available historical experience and on various other factors that the Company believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from those estimates.

Significant estimates and assumptions include those related to the valuation of (i) certain equity awards, including common stock awards prior to the Business Combination, the Sponsor Earn-Out Shares, the Earn-Out Restricted Shares, and performance stock units, (ii) deferred tax assets and uncertain income tax positions, and (iii) and the measurement of operating lease liabilities. On an ongoing basis, the Company evaluates these judgments and estimates for reasonableness.

Investments

The Company has investments in marketable debt and marketable equity securities. Investments in marketable debt securities, which are comprised of U.S. treasury securities, are classified as available-for-sale and are recorded at fair value with any unrealized gains and losses included as a component of accumulated other comprehensive loss in total stockholders’ equity on the consolidated balance sheets until realized or until a determination is made that an other-than-temporary decline in market value has occurred. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, with such amortization and accretion reported within interest income, net in the consolidated statement of operations and comprehensive loss. Marketable debt security investments with a stated maturity date of less than one year are classified as short-term investments, while those with a stated maturity date of more than one year, and that are not expected to be used in current operations, are classified as long-term investments on the consolidated balance sheet, respectively. Investments in marketable equity securities with a readily determinable fair value, not accounted for under the equity method, are recorded at fair value with changes to fair value reported within other income (expense), net in the consolidated statements of operations and comprehensive loss.

Fair Value Measurements

Fair value is defined as an exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be either recorded or disclosed at fair value, the Company considers the principal or most advantageous market in which it would transact, and it also considers assumptions that market participants would use when pricing the asset or liability.

The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. GAAP establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1    Observable inputs such as quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2    Inputs other than the quoted prices in active markets that are observable either directly or indirectly.

Level 3    Unobservable inputs in which there are little or no market data and which require the Company to develop its own assumptions.

Certain of the Company’s financial instruments, including cash and cash equivalents, accounts payable, accrued expenses and other current liabilities are carried at cost, which approximates their fair value because of their short-term nature. The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis:

Sponsor Earn-Out Liability

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Sponsor Earn-Out Liability

Note 8.  Sponsor Earn-Out Liability

On February 2, 2022, in connection with the Domestication, 6,900,000 of Ivanhoe’s Class B ordinary shares held by Ivanhoe Capital Sponsor LLC (the “Sponsor”) converted into an equal number of shares of duly authorized, validly issued, fully paid and nonassessable Class B common stock, par value $0.0001 per share (the “Class B Common Stock”), of the Company. At Closing, these 6,900,000 shares of Class B Common Stock converted into an equal number of shares of duly authorized, validly issued, fully paid and nonassessable Class A common stock par value $0.0001 per share (the “Class A Common Stock”, and together with the Class B Common Stock, “Common Stock”), of the Company (the “Sponsor Earn-Out Shares”). These Sponsor Earn-Out Shares are subject to certain transfer restrictions and forfeiture terms following the Closing, which will be released as follows:

● 20% were subject to transfer restrictions until the date that was 180 days after the Closing (“Tranche 1”);

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $12.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 2”);

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $14.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 3”);

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $16.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 4”); and

● 20% are subject to transfer restrictions until SES’s closing stock price equals or exceeds $18.00 for 20 out of 30 consecutive trading days following the date that is 150 days after the Closing (“Tranche 5”).

If there is a change in control of SES at a per share value of greater than $18.00, then 100% of the Sponsor Earn-Out Shares will be released from these transfer restrictions; however if the per share value is less than $18.00 upon a change in control, then the Sponsor Earn-Out Shares will be released pro rata based on the per share value of the change in control and the stock price thresholds for release specified above. Any Sponsor Earn-Out Shares not released will be forfeited and cancelled.

The Sponsor Earn-Out Shares in Tranche 1 were accounted for as equity instruments because they are legally owned by the Sponsor, cannot be forfeited and were subject only to transfer restrictions that lapsed 180 days after the Closing Date, which occurred on August 2, 2022. The Sponsor Earn-Out Shares in Tranches 2 through 5 represent the Sponsor Earn-Out Liability and are accounted for as a derivative liability because the earn-out triggering events that determine the number of Sponsor Earn-Out Shares to be earned back by the Sponsor include events that are not solely indexed to the shares of Class A common stock.

The Sponsor Earn-Out Liability is measured at its estimated fair value using Level 3 inputs in a Monte Carlo simulation valuation model. As of the three months ended March 31, 2023, the earn-out triggering events were not achieved for any of Tranche 2 through Tranche 5,

and as such the Company adjusted the carrying amount of the Sponsor Earn-out Liability to its estimated fair value of $10.4 million in the condensed consolidated balance sheet.

The following table provides a reconciliation of the beginning and ending balances for the Sponsor Earn-Out Liability:

		(in thousands)
Balance as of December 31, 2022	$	10,961
Additions during the period		—
Change in fair value		(569)
Balance as of March 31, 2023	$	10,392

Inherent in the valuation model are assumptions related to expected stock price volatility, risk-free interest rate, expected life, and dividend yield. The key inputs used in the Monte Carlo simulation model at their respective measurement dates were as follows:

		March 31, 2023		December 31, 2022
Contractual term (in years)		3.8		4.1
Risk free rate		3.76%		4.09%
Expected volatility		90.0%		85.0%
Expected dividends		0%		0%
Stock price	$	2.95	$	3.15

The stock price is based on the closing price of the Company’s Class A common stock as of the valuation date and simulated through the end of the earn-out period following Geometric Brownian Motion. The Company estimates the volatility of its common stock by using an average of historical volatilities of SES’s and select peer companies’ common stock that matches the expected remaining term of the awards. The risk-free interest rate is based on the yield curve for zero-coupon U.S. Treasury notes with maturities corresponding to the expected remaining life of the awards, which is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

Commitments and Contingencies

Note 9.  Commitments and Contingencies

Commitments

Under the terms of one of the JDAs, the Company is committed to undertake certain research and development activities to the benefit of both itself and its OEM Partner which involves expenditures related to engineering efforts and purchases of related equipment. This JDA has an agreed-upon value of up to $50 million, of which the Company has spent $2.5 million as of March 31, 2023.

In December 2021, the Company amended the lease agreement on an office space in Woburn, Massachusetts. The amendment includes an obligation to pay monthly relinquishment charges (equal to the total rental obligation for the duration of the lease term), only if the new tenant does not pay monthly rental amount and lessor has provided a notice to collect the relinquishment charges from the Company. As of March 31, 2023, the Company assessed the probability of any liability to be incurred for relinquishment charges as remote.

Legal Contingencies

From time-to-time, the Company may be subject to claims arising in the ordinary course of business or become involved in litigation or other legal proceedings. While the outcome of such claims or other proceedings cannot be predicted with certainty, the Company’s management expects that any such liabilities, to the extent not provided for by insurance or otherwise, would not have a material effect on the Company’s financial condition, results of operations or cash flows.

Indemnifications

The Company enters into indemnification provisions under agreements with other companies in the ordinary course of business, including, but not limited to, partnerships, landlords, vendors, and contractors. Pursuant to these arrangements, the Company agrees to indemnify, defend, and hold harmless the indemnified party for certain losses suffered or incurred by the indemnified party as a result of the Company’s activities. The maximum potential amount of future payments the Company could be required to make under these agreements is not

determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification provisions. In addition, the Company indemnifies its officers, directors, and certain key employees against claims made with respect to matters that arise while they are serving in their respective capacities as such, subject to certain limitations set forth under applicable law, and applicable indemnification agreements. The Company maintains insurance, including commercial general liability insurance, product liability insurance, and directors and officers insurance to offset certain potential liabilities under these indemnification provisions. To date, there have been no claims under these indemnification provisions.

Income Tax Disclosure [Abstract]

Income Taxes

Note 11.   Income Taxes

The Company’s effective tax rate for the three months ended March 31, 2023 was (0.9)%, compared with 0% for the three months ended March 31, 2022. The difference between the provision for income taxes and the income tax determined by applying the statutory federal income tax rate of 21% principally results from income taxes on earnings from its foreign tax jurisdictions offset by losses generated in the U.S. where no benefit was recorded because the Company had fully reserved its deferred tax assets as of March 31, 2023 and December 31, 2022 and the recording of uncertain tax positions and interest expense.

As of March 31, 2023, there were $0.9 million in changes to the total amount of unrecognized tax benefits related to transfer pricing adjustments.

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Note 12.  Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing net income (loss), as adjusted for changes in fair value recognized in earnings from equity contracts classified as liabilities, by the weighted average number of common shares outstanding and, when dilutive, common share equivalents from outstanding stock options and restricted stock units (using the treasury-stock method). The weighted-average number of common shares used in the computation of basic and diluted net income per share were as follows:

	Three Months Ended March 31,
(in thousands, except share and per share amounts)	2023		2022
Numerator:
Net loss attributable to common stockholders - basic	$	(16,226)	$	(27,033)
Denominator:

Net loss per share attributable to common stockholders - basic and diluted	$	(0.05)	$	(0.12)

The number of common stock equivalents excluded from the computation of diluted net loss per share because either the effect would have been anti-dilutive, or the performance criteria related to such shares and awards had not been met, were as follows:

Basis of Presentation and Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and are unaudited. These financial statements do not include all of the annual disclosures required by U.S. GAAP; accordingly, they should be read in conjunction with the audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 16, 2023 (the “Annual Report”). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the condensed consolidated financial statements for the interim periods presented. The results of operations for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the full year or any other future interim or annual periods. All intercompany balances and transactions have been eliminated in consolidation. As a result of the Business Combination completed on February 3, 2022, prior period share and per share amounts presented in the accompanying condensed consolidated financial statements and these related notes have been retroactively converted. The Company’s fiscal year ends on December 31.

During the three months ended March 31, 2023, there have been no significant changes to the Company’s significant accounting policies as disclosed in “Note 2 – Basis of Presentation and Summary of Significant Accounting Policies” of the Company’s above mentioned Annual Report, except as described below.

Reclassification of Prior Period Amounts

Reclassification of Prior Period Amounts

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. The Company reclassified the change in accrued compensation and the change in operating lease liabilities to the change in accrued expenses and other liabilities in the prior year’s statements of cash flows in the amount of $0.6 million and ($0.3) million for the three months ended March 31, 2022, respectively. There was no change to previously reported net cash used in operating activities.

Use of Estimates

Use of estimates

The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires management to make use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of commitments and contingencies, and the reported amounts of revenues, if any, and expenses. The Company bases its estimates on available historical experience and on various other factors that the Company believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from those estimates.

Significant estimates and assumptions include those related to the valuation of (i) certain equity awards, including common stock awards prior to the Business Combination, the Sponsor Earn-Out Shares, the Earn-Out Restricted Shares, and performance stock units, (ii) deferred tax assets and uncertain income tax positions, and (iii) and the measurement of operating lease liabilities. On an ongoing basis, the Company evaluates these judgments and estimates for reasonableness.

Investments

Investments

The Company has investments in marketable debt and marketable equity securities. Investments in marketable debt securities, which are comprised of U.S. treasury securities, are classified as available-for-sale and are recorded at fair value with any unrealized gains and losses included as a component of accumulated other comprehensive loss in total stockholders’ equity on the consolidated balance sheets until realized or until a determination is made that an other-than-temporary decline in market value has occurred. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, with such amortization and accretion reported within interest income, net in the consolidated statement of operations and comprehensive loss. Marketable debt security investments with a stated maturity date of less than one year are classified as short-term investments, while those with a stated maturity date of more than one year, and that are not expected to be used in current operations, are classified as long-term investments on the consolidated balance sheet, respectively. Investments in marketable equity securities with a readily determinable fair value, not accounted for under the equity method, are recorded at fair value with changes to fair value reported within other income (expense), net in the consolidated statements of operations and comprehensive loss.

Fair Value Measurements

Fair Value Measurements

Fair value is defined as an exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be either recorded or disclosed at fair value, the Company considers the principal or most advantageous market in which it would transact, and it also considers assumptions that market participants would use when pricing the asset or liability.

The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. GAAP establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1    Observable inputs such as quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2    Inputs other than the quoted prices in active markets that are observable either directly or indirectly.

Level 3    Unobservable inputs in which there are little or no market data and which require the Company to develop its own assumptions.

Certain of the Company’s financial instruments, including cash and cash equivalents, accounts payable, accrued expenses and other current liabilities are carried at cost, which approximates their fair value because of their short-term nature. The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis:
