Dec. 31, 2021

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

In connection with the closing of the Business Combination, whereby Legacy Amprius was determined as the accounting acquirer for accounting and reporting purposes, the historical financial statements of Legacy Amprius became the historical financial statements of the combined company and no goodwill or other intangible assets were recorded. As a result, the accompanying condensed financial statements reflect (i) the assets and liabilities of Legacy Amprius at their historical cost; (ii) the historical operating results of Legacy Amprius prior to the Business Combination; (iii) the combined results of the Company and Legacy Amprius following the closing of the Business Combination; and (iv) Legacy Amprius’ equity structure, which has been retroactively restated in all comparative periods up to the Closing Date to reflect the number of shares of the Company’s common stock issued to Legacy Amprius stockholders. As such, the shares, corresponding capital amounts, and net loss per share related to Legacy Amprius common stock have been retroactively restated to reflect the effect of the exchange ratio of 1.45590 (the “Exchange Ratio”) established in the Business Combination.

The accompanying condensed financial statements have been prepared from the financial records of Amprius Holdings on a

carve-out

basis. The

carve-out

basis is derived from the accounting records of Amprius Holdings using the historical results of operations and the historical basis of assets and liabilities of the Company adjusted as necessary to conform to U.S. GAAP.

More specifically, the accompanying condensed balance sheets include all of the Company’s owned assets, assets provided by Amprius Holdings, and liabilities incurred by Amprius Holdings on behalf of the Company. The accompanying condensed statements of operations reflect all activities directly attributable to the Company, as well as an allocation of Amprius Holdings’ general and administrative expenses. The Company did not share facilities or costs with the other subsidiaries of Amprius Holdings prior to them being distributed by Amprius Holdings with the exception of expenses at Amprius Holdings for payroll related expenses for two executive employees of Amprius Holdings and other legal, tax, insurance and accounting fees, which were not identifiable as related to a specific subsidiary (“Shared Expenses”). Amprius Holdings executives supported the Company and other subsidiaries of Amprius Holdings with governance, management, and investor relations. The Shared Expenses were allocated to the Company based on the time incurred by Amprius Holdings executives to support each of its subsidiaries as the level of effort required was not correlated to the level of activity, revenue, or other financial operating metrics for the subsidiaries. This allocation methodology resulted in an equal allocation of Shared Expenses to each subsidiary. Prior to the distribution of the subsidiaries of Amprius Holdings in late January and early February 2022, the general and administrative expenses of Amprius Holdings were allocated among each subsidiary, including the Company. After the distribution, such costs incurred by Amprius Holdings were wholly allocated to the Company as the only remaining subsidiary.

Prior to the Closing of the Business Combination, the Company’s operations were funded by Amprius Holdings. The source of financing consisted of proceeds received by Amprius Holdings from its issuance of preferred stock.

Management believes the expense allocation methodology and results are reasonable and consistently applied for all comparative periods presented. However, these allocations may not be indicative of the actual expenses that would have been incurred by an independent company or of the costs to be incurred in the future. The unaudited condensed financial statements presented may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as a standalone company during the period presented.

The significant accounting policies described below, together with other notes that follow, are an integral part of the condensed financial statements.

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). As the Parent has not historically prepared financial statements for the Company, these financial statements have been prepared from the financial records of the Parent on a

carve-out

basis derived from the accounting records of the Parent using the historical results of operations and the historical basis of assets and liabilities of the Company, adjusted as necessary to conform to U.S. GAAP.

More specifically, the balance sheets include all the Company’s legal assets, those assets provided by the Parent and liabilities incurred by the Parent on behalf of the Company. The statements of operations for each of the years ended December 30, 2021 and 2020, reflect all expenses and activities directly attributable to the Company, as well as an allocation of the Parent’s general and administrative expenses. The Company did not share facilities or costs with the other three operating subsidiaries with the exception of expenses at Parent for the payroll related expenses for two executive employees of Parent and other legal, tax, insurance and accounting fees which were not identifiable as related to a specific subsidiary (“Shared Expenses”). The Parent executives supported the subsidiary group with governance, management, and investor relations. The Shared Expenses were allocated to the Company based on the time incurred by the Parent executives to support each subsidiary as the level of effort required was not correlated to the level of activity at each subsidiary, revenue, or other financial operating metrics for the subsidiaries.

Management’s estimate of incremental expenses that would have been incurred on a standalone basis for the year ended December 31, 2021 and 2020 were approximately $3,479 and $895, respectively. These expenses consisted of incremental compensation and benefits associated with certain senior executives necessary to depict the Company on a standalone basis.

During the years ended December 30, 2021 and 2020, the Company’s operations were funded by the Parent. The source of financing consisted of proceeds received by the Parent from its issuance of preferred stock.

Management believes the expense allocation methodology and results are reasonable and consistently applied for all comparative periods presented. However, these allocations may not be indicative of the actual expenses that would have been incurred by an independent company or of the costs to be incurred in the future. The financial statements may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as a standalone company during the period presented.

The significant accounting policies described below, together with other notes that follow, are an integral part of the financial statements.

Emerging Growth Company

The Company is an emerging growth company as defined in Section 2(a) of the Securities Act of 1933 (as amended), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised accounting standards until private companies are required to comply with such standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to

non-emerging

growth companies but any such election to opt out is irrevocable. The Company has elected to not opt out of such extended transition period. This means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt such new or revised standard unless the Company is no longer deemed an emerging growth company. As a result, these condensed financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Emerging Growth Company

The Company is an “emerging growth company” as defined in Section 2

(a) of the Securities Act, and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. Further, Section 102

(b)(1)

of the Jumpstart Our Business Startups (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to

non-emerging

growth companies, but any such election to opt out is irrevocable.

The Company has elected not to opt out of such extended transition period. This means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as

an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Use of Estimates

The preparation of condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances; the results of which form the basis for making judgements that are not readily apparent from other sources. Actual results could materially differ from management estimates using different assumptions or under different conditions.

Significant accounting estimates made by the Company include useful lives of property and equipment, valuation of deferred taxes, valuation of inventory,

carve-out

of condensed financial statements including the allocation of assets, liabilities and expenses, incremental borrowing rate used in calculating lease obligations and

right-of-use

asset, and fair value of common stock used to determine stock-based compensation expense prior to the merger with Kensington, and other inputs used to value stock-based compensation awards.

Significant accounting estimates made by the Company include the following useful lives of property and equipment; evaluation of impairment of long-lived assets; valuation of deferred taxes; valuation of inventory;

carve-out

of financial statements including the allocation of assets, liabilities and expenses; and the valuation of the fair value of common stock used to determine stock-based compensation expense.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and accounts receivable.

Cash is deposited with a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250. As of September 30, 2022 and December 31, 2021, the Company has not experienced losses on this account and management believes the Company is not exposed to significant risks of loss.

Accounts receivable mainly consist of amounts due from U.S. government agencies or sponsored entities and large public entities which limits the Company’s credit risk. Through September 30, 2022, the Company has not experienced any credit losses.

For the three months ended September 30, 2022 and 2021

, two customers and one customer represented

82%

and

82%

of the Company’s revenues, respectively. For the nine months ended September 30, 2022 and 2021, four and two customers represented

83% and 84%

of the Company’s revenues, respectively.

As of September 30, 2022 and December 31, 2021, three and five customers represented

76% and 96%

respectively, of the Company’s total accounts receivable.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and account receivables. The Company’s cash as of December 31, 2021 consists of a demand deposit

account. Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $

250. As of December 31, 2021 and 2020, the Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Accounts receivable mainly consist of amounts due from U.S. government agencies or sponsored entities and large public entities, which limits the Company’s credit risk. Through December 31, 2021, the Company has not experienced any credit losses.

For the year ended December 31, 2021, two customers represented 56%, and 24% of the Company’s revenues. For the year ended December 31, 2020, three customers represented 49%, 36% and 10% of the Company’s revenues. As of the year ended December 31, 2021, five customers accounted for 25%, 19%, 19%, 18%, and 15% of the Company’s accounts receivable balance. As of December 31, 2020, two customers accounted for 86% and 14% of the Company’s accounts receivable balance.

Cash and cash equivalents

Cash

The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash and cash equivalents. During the year ended December 31, 2020, cash was provided

to the Company by the Parent on a “as needed” basis by drawing on a cash sweep account maintained by the Parent. Subsequent to January 1, 2021, upon cash contributions from the Parent of $16,200, the Company maintained a balance in its operating cash account to fund operations.

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents consist of deposits at banks and a money market fund with original maturities of 90 days or less from the date of purchase.

Restricted cash pertains to cash collateral required by the Company’s lessor to satisfy a letter of credit requirement under its lease agreement. As of September 30, 2022, restricted cash was $333 and is included in other assets in the accompanying condensed balance sheet.

Fair Value of Financial Instruments

The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:

Level 1 -

Inputs that are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 -

Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 -

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities, and which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

There were no financial assets or financial liabilities measured at fair value on a recurring basis as of December 31, 2021 and 2020.

Fair Value Measurements

The carrying amounts of cash, accounts receivable, accounts payable, and accrued liabilities approximate fair value because of the short-term nature of these items. Assets and liabilities recorded at fair value in the financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity, associated with the inputs to the valuation of these assets or liabilities are as follows:

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.

The Company had $72,828 of cash equivalents measured at Level 1 fair value on a recurring basis as of September 30, 2022.

Segment Reporting

The Company has determined that the Chief Executive Officer is its Chief Operating Decision Maker (CODM). The CODM reviews financial information presented on an aggregate basis for the purposes of assessing the Company’s performance and making decisions on how to allocate resources. Accordingly, the Company has determined that it operates in a single operating and reportable segment. All of the Company’s revenues are geographically earned in the United States and the Company’s property and equipment are located in the United States.

The Company’s Chief Executive Officer reviews financial information presented on an aggregate basis for the purposes of assessing the Company’s performance and making decisions on how to allocate resources. Accordingly, the Company has determined that it operates in a single operating and reportable segment. All of the Company’s revenues are geographically earned in the United States and the Company’s property and equipment are located in the United States.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount less any estimated allowance for doubtful accounts. An allowance for doubtful accounts is based on the Company’s assessment of the collectability of accounts by considering the age of outstanding invoices and the collection history of the customer, as well as an evaluation of potential risk of loss. A receivable deemed to be uncollectible is written off against a previously established allowance and recoveries are recognized when the cash is received. The Company has not experienced any significant losses from accounts receivable.

Accounts Receivable

Accounts receivable is recorded at the invoiced amount less any estimated allowances for doubtful accounts. These allowances are based on the Company’s assessment of the collectability of accounts by considering the age of each outstanding invoice and the collection history of each customer, and an evaluation of the potential risk of loss associated with delinquent accounts. Payment terms and conditions vary by contract type, although the Company’s terms generally include a requirement of payment within 30 to 60 days. Accounts receivable balances deemed to be uncollectible are written off against previously established allowances. The Company does not accrue interest on past due balances and requires no collateral. Through December 31, 2021, the Company has not experienced any credit losses from accounts receivable. The Company had no allowance for doubtful accounts as of December 31, 2021 and 2020.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). Income taxes in the Company’s financial statements have been allocated in a manner that is systematic, rational, and consistent. The Company’s operations have historically been included in the Parent’s combined U.S. income tax returns. Income tax expense included in the financial statements has been calculated following the separate return method, as if the Company was a stand-alone enterprise and a separate taxpayer for the periods presented. As a result, actual tax transactions included in the consolidated financial statements of the Parent may not be included in these financial statements. Further, the Company’s tax results may not be reflective of the results that the Company expects to generate in the future. The tax treatment of certain items reflected in the financial statements may not be reflected in the consolidated financial statements and tax returns of the Parent. It is conceivable that items such as net operating losses, other deferred taxes, uncertain tax positions and valuation allowances may exist in the financial statements that may not exist in these financial statements.

Since the Company’s results are included in the Parent’s historical tax returns, payments to certain tax authorities are made by the Parent, and not by the Company. For tax jurisdictions where the Company is included with the Parent in a consolidated tax filing, the Company does not maintain taxes payable to or from the Parent and the payments are deemed to be settled immediately with the legal entities paying the tax in the respective tax jurisdictions through changes in the Parent company contributions.

Concurrently with the execution of the Business Combination Agreement, the Company and the Parent entered into the Tax Sharing Agreement. The Tax Sharing Agreement generally provides that, with respect to any U.S. federal consolidated group of which the Parent and the Company are members, the Parent will be responsible for and will indemnify the Company for the tax liability of such group. In addition, the Parent will be responsible for and will indemnify the Company for state taxes of any consolidated, combined or unitary tax group for state tax purposes that includes the Parent and the Company. The Tax Sharing Agreement also provides that the Parent will generally control any tax returns and any tax audits or other proceedings for the taxes addressed by the Tax Sharing Agreement. The Tax Sharing Agreement terminates on the termination of the Business Combination Agreement. The Company does not expect the Tax Sharing Agreement to have a material impact on the results of the Company’s operations on a

go-forward

basis.

The Company follows the asset and liability method of accounting for income taxes. Deferred tax balances are recognized for the estimated future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets are also recognized for temporary differences that arise from net operating losses and

credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax balances of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be

more-likely-than-not

to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense.

Net Income (Loss) per Ordinary Share

Net Loss Per Share

Basic net loss per share is computed using the weighted-average number of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock and potentially dilutive securities outstanding for the period. The Company’s potentially dilutive shares consist of shares issuable upon the exercise of stock options. These have been excluded from the diluted loss per share calculation because their effect is anti-dilutive. The basic and diluted loss per share are therefore the same.

Recently Adopted Accounting Standards

In February 2016, FASB issued ASU

2016-02,

Leases,

and subsequent amendments to the initial guidance: ASU

2017-13,

ASU 2018-10,

ASU 2018-11,

ASU

2018-20

and ASU

2019-01

(collectively, “Topic 842”). Lessees will need to recognize almost all leases on their balance sheet as a

right-of-use

asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance, including guidance for real estate, is replaced with a new model applicable to both lessees and lessors. The Company adopted Topic 842 on January 1, 2022, using the modified retrospective approach, therefore, the effects of adoption on comparative periods have not been and are not required to be restated or disclosed.

As of the adoption date, the Company accounts for its leases under ASC 842,

Leases

. Under this guidance, lessees classify arrangements meeting the definition of a lease as operating or financing leases, and leases are recorded on the balance sheet as both

a right-of-use asset

and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of

the right-of-use asset

result in straight-line rent expense over the lease term. For finance leases, interest on the lease liability and the amortization of

the right-of-use asset

results in front-loaded expense over the lease term. Variable lease expenses, including common maintenance fees, insurance and property tax, are recorded when incurred.

In calculating

the right-of-use asset

and lease liability, the Company elects to combine lease

and non-lease components

for its real estate lease. The Company will assess this election for other asset classes as they arise. The Company excludes short-term leases having initial terms of 12 months or less as an accounting policy election, and instead recognizes rent expense on a straight-line basis over the lease term.

The Company has a single lease of a real estate asset, which includes administrative and sales offices, research and development space, manufacturing and a dry room. This lease also requires the Company to pay maintenance, utilities, taxes, insurance, and other operating expenses associated with the leased space. The Company elected the transition package of three practical expedients which allow companies not to reassess whether agreements contain leases, the classification of leases, and the capitalization of initial direct costs.

As a result of the adoption of Topic 842, the lease continued to be classified as an operating lease, and the Company recognized the following on January 1, 2022:

•

Operating lease liabilities of $3,256, which represents the present value of the remaining lease payments, as of the date of adoption, discounted using the Company’s incremental borrowing rate of 7.9%.

•

Operating lease

right-of-use

(“ROU”) assets of $3,059, which represents the operating lease liabilities of $3,256, adjusted for deferred rent of $240 and prepaid rent of $43.

•

The adoption of the new lease accounting standard increased the Company’s accumulated deficit by $154.

The adoption of Topic 842 did not have any other impact on the Company’s condensed balance sheet as of September 30, 2022, operating results for the three and nine months ended September 30, 2022, and condensed cash flows for the nine months ended September 30, 2022.

In November 2021, the FASB issued ASU

2021-10,

Government Assistance

(Topic 832),

Disclosures by Business Entities About Government Assistance

, which requires entities to provide disclosures on material government transactions for annual reporting periods. The disclosures include information around the nature of the assistance, the related accounting policies used to account for government assistance, the effect of government assistance on the entity’s financial statements, and any significant terms and conditions of the agreements, including commitments and contingencies. The ASU is effective for financial statements issued for annual periods beginning after December 15, 2021, with early adoption permitted. The Company adopted this guidance on January 1, 2022, with no impact on the Company’s condensed financial statements and related disclosures as the Company does not have any government assistance accounted for by applying a grant or contribution accounting model by analogy in the periods presented.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU

2019-12,

Income Taxes

(Topic 740):

Simplifying the Accounting for Income Taxes

(“ASU 2019-02”), which is intended to simplify various aspects related to accounting for income taxes. ASU

2019-12

removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company adopted this standard on January 1, 2021, and it did not have a material impact on the Company’s financial statements or the related disclosures.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the

first-in-first-out

cost method. The inventory consists of raw materials as well as finished goods and

work-in-process

that include material, labor and manufacturing overhead costs. The Company routinely evaluates inventory levels in light of current market conditions in order to identify excess and obsolete inventory, and the Company provides a write-down for certain inventories to their estimated net realizable value. Manufacturing cost of finished goods generally exceed the sales price charged to customers. All products are built to customer orders, as such finish goods are valued no higher than the sale price less selling costs of the customer order.

Work-in-process

and raw materials are valued at the sale price of the customer orders less the estimated cost to complete and selling costs. The Company assesses raw materials and

work-in-process

for impairment if the expected finished good has a cost above its estimated selling price less selling costs. When a write-down is recorded, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in the new cost basis.

The Company recorded a reduction to the value of inventories to cost of revenue of $75 and $58 during the years ended December 31, 2021 and 2020,

respectively

Property and Equipment, Net

Property and equipment are stated at cost, net of accumulated depreciation. These assets are depreciated on a straight-line basis over their estimated useful lives. The useful lives of the property and equipment are as follow:


Pilot production equipment		4-7 years
Lab equipment		4 years
Computers and software		4 years
Furniture and fixtures		5 years
Leasehold improvements		Lesser of their useful lives or the term of the lease

Certain custom assets are recorded as construction in progress as they are being constructed. Completed assets are transferred to their respective asset classes, and depreciation begins when an asset is ready for its intended use. Maintenance and repairs are charged to operations as incurred.

Impairment of Long-Lived Assets

The Company periodically evaluates the carrying value of long-lived assets to be held and used when indicators of impairment exist. The carrying value of a long-lived asset to be held and used is considered impaired when the estimated separately identifiable undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using the estimated cash flows discounted at a rate commensurate with the risk involved. No impairment charges were recorded for the years ended December 31, 2021 and 2020.

Warranty Liability

The Company warrants the batteries sold to customers will meet the published or agreed upon specification upon receipt. Batteries that do not meet specification are replaced at no charge to the customer. Based on the experience of historical claims and no pending claims and returns of which the Company is aware, the Company had not recorded a warranty liability as of December 31, 2021 or 2020.

Revenue Recognition

The Company recognizes revenue under ASC Topic 606,

Revenue from Contracts with Customers

, when a customer obtains control of promised goods or services in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services.

The Company generates revenue from both its arrangements for customization design services for the development of silicon-anode

lithium-ion

battery technology and delivery of prototypes and providing finished battery products to its customers.

The customization design services generally provide design and development efforts to configure the Company’s existing battery technology towards a customer’s required specifications, including the delivery of the prototypes. The development and delivery of these battery prototypes is a single performance obligation as the individual customization activities performed through delivery of the prototype batteries are not distinct. Revenue is recognized at the point in time when control transfers to the customer upon final delivery of prototype batteries or completion of the defined service.

The Company recognizes revenue from

follow-on

orders and standalone sales of battery products to customers at the point in time that control of the product has been transferred to the customer which is generally upon shipment.

To achieve the core principle of revenue recognition, the Company applies the following steps:

Identify the contract with the customer.

A contract is defined as an agreement between two or more parties that creates enforceable rights and obligations. The Company generally enters into fixed-price agreements with its customers which outline the terms of the business relationship between the customer and the Company. Additionally, the Company may receive purchase orders from customers or enter into statements of work that indicate pricing, performance and delivery obligations, progress payments (if any) and the timing for each transaction. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of the consideration is probable. At contract inception, the Company also evaluates prior incomplete contracts to determine whether the contract with the customer should be combined and accounted for as a single contract with any prior contract.

Identify the performance obligations in the contract.

The promises within each contract for customization design services may vary depending on the customer requirements; however, those contracts contain promises which generally include (i) custom battery design to conform with customer’s requirements, (ii) design progress reporting, (iii) development of preliminary batteries, (iv) testing of battery design and performance, and (v) delivery of final battery prototypes that meet

pre-defined

customer specifications along with test results of the delivered batteries. Those promises are generally inputs to a combined output to deliver a single final prototype battery and are accounted for as a single performance obligation. Contracts for standard batteries for commercial sales are generally ready-made with no customization. Within these contracts, each battery is a distinct performance obligation.

Determine the transaction price

. Payment terms for the Company’s development contracts are generally based on the achievement of defined milestones. Since revenue is generally recognized at the point in time when control transfers to the customer upon final delivery of prototype battery or completion of the service at the end of the contract as discussed below in Step 5

, Recognize revenue when, or as, a performance obligation is satisfied

, the variable consideration is not considered to be constrained at the inception of the contract and the transaction price equals the cumulative payments to which the Company is entitled to at the end of the contract. The Company elected to use the practical expedient to disregard the effect of the time value of money in a significant financing component when its payment terms are less than one year. In cases when there is a period of more than one year, the Company only adjusts the transaction price when the financing component is significant and beyond the mitigating effect of the progress payments.

Allocate the transaction price to the performance obligations in the contract

. The transaction price is allocated to the performance obligations. The Company’s revenue contracts contain a single performance obligation; therefore, allocation is not necessary.

Recognize revenue when, or as, a performance obligation is satisfied

. Under the Company’s customized design services arrangements, control generally transfers upon the completion of the battery design and delivery of the final prototype batteries. For

follow-on

orders and standalone sales of battery products to customers, control generally transfers upon shipment of the product. In some instances, customers may request that the Company bill them for a product but the Company retains physical possession of the product until later delivery, commonly known as

“bill-and-hold”

arrangements. The Company has a customer that has requested an arrangement whereby the Company may store finished product until the customer’s employees arrive at a specific site for a customer flight test. The finished products for such customer are stored in a storage area that are identified separately as belonging to such customer and are ready for immediate shipment upon the customer’s request.

Additionally, title and risk of loss has passed to the customer. as such, the Company does not have the ability to use the finished products or direct them to other customers. In these

“bill-and-hold”

arrangements, the Company recognizes revenue when the product is identified separately as belonging to the customer and the product is ready for delivery to the customer.

Loss Contingencies

In the normal course of business, the Company may be involved in claims and legal proceedings. The Company records a liability for such matters when it is probable that a loss has been incurred and the amounts can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. Legal costs associated with these loss contingencies are expensed as incurred.

Deferred Costs

Certain costs, which consist primarily of payroll-related costs, are initially deferred when (i) the costs relate directly to a customer contract, (ii) generate or enhance resources of the Company that will be used in satisfying future performance obligations, and (iii) are expected to be recovered. If these three criteria are not met, the costs are expensed into cost of revenue in the period incurred. Deferred costs are recognized as cost of revenues in the period when the related revenue is recognized, except when such costs incurred are in excess of the amount expected to be recoverable, in which case they are expensed as incurred into cost of revenues. The recoverable amount equals the total of the amount of consideration that the entity expects to receive in the future and that the entity has received but has not recognized as revenue, in exchange for the goods or services to which the asset relates, less the costs that relate directly to providing those goods or services and that have not been recognized as expenses.

Deferred

Costs

Capitalization of certain costs are recognized as an asset when the costs relate directly to a customer contract, generate or enhance resources of the Company that will be used in satisfying future performance obligations, and are expected to be recovered. If these three criteria are not met, the costs are expensed in the period incurred. Deferred costs are recognized as cost of revenues in the period when the related revenue is recognized, except when such costs incurred are in excess of the amount expected to be recoverable, in

which case they are expensed as incurred into cost of revenues. The recoverable amount equals the amount of consideration that the entity expects to receive in the future and that the entity has received but has not recognized as revenue, in exchange for the goods or services to which the asset relates, less the costs that relate directly to providing those goods or services and that have not been recognized as

expenses

Cost of Revenues

Cost of revenues primarily includes cost of materials, direct labor costs, and allocation of indirect costs, such as facilities and overhead expenses. Costs are recognized when incurred during the period revenue is recognized.

Cost of Revenues

Cost of revenues include materials, direct labor, allocated depreciation expense, and other direct and indirect costs related to revenue contracts. The costs are recognized as and when incurred during the period revenue is recognized.

Research and Development Costs

Research and development (“R&D”) costs mainly consist of salaries and benefits, including stock-based compensation expense and other related personnel costs, depreciation, contract services, materials and supplies, other expenses from outside contractors and suppliers plus an allocation of indirect costs. These costs relate to the conceptual formulation and design of preproduction experimental prototypes and models, including the cost of equipment and material for which there is no alternative future use. The Company capitalizes equipment related to its pilot line used in R&D as it determined that the equipment has alternative future uses in future R&D projects. R&D cost are expensed as incurred.

Advertising Costs

Advertising costs were $44 and $10 for the years ended December 31, 2021 and 2020, respectively, and have been expensed as incurred as selling, general and administrative expense within the statements of operations.

Stock-Based Compensation

Prior to the formation of the Company, certain employees, directors, and contract workers were granted stock option awards under Amprius Holdings’ equity incentive plan. The stock-based compensation costs of those stock option awards to employees, directors and contract workers, who were transferred to the Company or continued to provide services to the Company, were recorded by the Company with a corresponding increase to additional

paid-in

capital.

In 2016, the Company adopted its equity incentive plan separate from the equity incentive plan of Amprius Holdings. Certain qualified employees, directors and contract workers of Amprius Holdings have received stock option awards of the Company. The cost of the stock-based compensation of those awards was recorded by the Company.

The Company measures stock-based compensation expense for all stock-based payment awards based on the estimated fair value of the awards on the date of grant. The fair value of each employee stock option is estimated on the date of grant using the Black-Scholes option-pricing model. The Company recognizes compensation costs for all employee stock-based compensation awards on a straight-line basis over the period from the date of the grant to the date the award is fully vested. The Company has elected to account for forfeitures as they occur.

The Black-Scholes option-pricing model requires the use of highly subjective assumptions which determine the fair value of stock-based awards. These assumptions include:

•

Expected Term — The expected term of stock options represents the period that the Company’s stock-based awards are expected to be outstanding. As the Company does not have sufficient historical

experience for determining the expected term, the expected term has been derived based on the simplified method for awards that qualify as plain-vanilla options.

•

Expected Volatility — The Company estimates volatility for option grants by evaluating the average historical volatility of a peer group of companies for the period immediately preceding the option grant for a term that is approximately equal to the option’s expected term.

•

Risk-Free Interest Rate — The Company bases the risk-free interest rate on the implied yield available on the U.S. Treasury zero coupon issues with a remaining term equivalent to the expected term of the option.

•

Expected Dividend — The expected dividend assumption is based on the Company’s current expectations about its anticipated dividend policy. The Company has not paid dividends since inception and currently, management does not anticipate a dividend.

To the extent that future evidence regarding these variables is available and provides estimates that the Company determines are more indicative of actual trends, the Company may refine or change its approach to derive these input estimates. These changes could significantly impact the stock-based compensation expense recorded in the future.

Stock-Based Compensation

Prior to the formation and incorporation of the Company, qualified employees, directors, and contract workers participated in the Parent’s equity incentive plan, including stock option awards. For those employees, directors and contract workers who were transferred to the Company or continued to provide services to the Company and received awards under the Parent’s incentive plan; costs of those awards are recorded as stock-based compensation with a corresponding contribution from the Parent based on the grant date fair value of the awards. After incorporation, the Company established its new equity incentive plan separate from the original equity incentive plan from the Parent. Certain qualified employees, directors and contract workers of the Parent have received stock option awards of the Company. The cost of the stock-based compensation of these awards was recorded by the Company.

The Company measures stock-based compensation expense for all stock-based payment awards based on the estimated fair value of the awards on the date of grant. The fair value of each employee stock option is estimated on the date of grant using the Black-Scholes option-pricing model. The Company recognizes compensation costs for all employee stock-based compensation awards on a straight-line basis over the period from the date of hire or of the grant to the date the award is fully vested. The Company has elected to account for forfeitures as they occur.

The Company estimates the fair value of stock options granted using the Black Scholes option-pricing model.

Expected Term

—The expected term of stock options represents the period that the Company’s stock-based awards are expected to be outstanding. As the Company does not have sufficient historical experience for determining the expected term, the expected term has been derived based on the simplified method for awards that qualify as plain-vanilla options.

Expected Volatility—

As the Company is privately held, there is no observable market for the Company’s common stock, and, accordingly, expected volatility has been estimated based on the volatilities of similar publicly-traded companies.

Risk-Free Interest Rate—

The Company bases the risk-free interest rate on the implied yield available on the U.S. Treasury zero coupon issues with a remaining term equivalent to the expected term of the option.

Expected Dividend—

The expected dividend assumption is based on the Company’s current expectations about its anticipated dividend policy. The Company has not paid dividends since inception and, currently, management does not anticipate a dividend.

Accounting Pronouncements Not Yet Effective

In February 2016, the FASB issued Accounting Standards Update (“ASU”)

2016-02

, Leases

(

Topic 842

) (“ASU 2016-02”) and subsequent amendments to the initial guidance: ASU

2017-13,

ASU 2018-10,

ASU

2018-11,

ASU

2018-20

and ASU

2019-01

(collectively, “Topic 842”). Lessees will need to recognize almost all leases on their balance sheet as a

right-of-use

asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance, including guidance for real estate, is replaced with a new model applicable to both lessees and lessors. ASU 2016-02 will be effective beginning after January 1, 2022. Early adoption is permitted. Management currently estimates the recognition of right of use (“ROU”) assets of $3,059 and lease liabilities for operating leases of $3,256

as of January 1, 2022, with a cumulative impact to accumulative deficit of $154. The ROU assets will be adjusted per Topic 842 transition guidance for the existing deferred rent balance.

In November 2019, the FASB issued ASU

Common Stock Warrants

The Company classified the common stock warrants as equity in accordance with FASB ASC Topic

815-40,

Derivatives and Hedging—Contracts in Entity’s Own Equity

. The classification is determined based upon the Company’s assessment that the common stock warrants are considered indexed to the Company’s own stock and the Company has the ability to settle them by issuing shares of the Company’s common stock.

Sales and Transaction Taxes

Sales and other taxes collected from customers and remitted to governmental authorities on revenue producing transactions are reported on a net basis and are therefore excluded from revenue in the condensed statements of operations.

Unaudited Interim Condensed Financial Statements

The condensed balance sheet as of December 31, 2021, which has been derived from audited financial statements as filed in the Company’s Registration Statement on Form

S-1

with the Securities and Exchange Commission (“SEC”) on September 30, 2022, and the unaudited interim condensed financial statements have been prepared in accordance with U.S. GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). The condensed financial statements have been prepared on a basis consistent with the audited annual financial statements. In management’s opinion, all adjustments made during the periods were normal or recurring in nature and necessary for the fair statement of the Company’s financial position as of September 30, 2022, its results of operations for the three and nine months ended September 30, 2022 and 2021 and its cash flows for the nine months ended September 30, 2022 and 2021. The financial data and the other financial information disclosed in the notes to these condensed financial statements related to the three-month and nine-month periods are also unaudited. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the full fiscal year or any other period.

Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading.

Inputs that are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities, and which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
