The following management's discussion and analysis should be read in conjunction with our financial statements and the notes thereto and the other financial information appearing elsewhere in this report. In addition to historical information, the following discussion contains certain forward-looking information. See "Special Note Regarding Forward Looking Statements" above for certain information concerning those forward-looking statements. Our financial statements are prepared inU.S. dollars and in accordance withU.S. GAAP. Overview
We are engaged in the development, manufacture and sale of new energy high power lithium batteries, as well as cathode materials and precursors for lithium batteries, which are mainly used in the following applications:
? Electric vehicles ("EV"), such as electric cars, electric buses, hybrid
electric cars and buses;
? Light electric vehicles ("LEV"), such as electric bicycles, electric motors,
sight-seeing cars; and
? Electric tools, energy storage including but not limited to uninterruptible
power supply application, and other high-power applications. In 2022, to meet a great demand for lithium-ion batteries, we have ramped up capacity in our Dalian manufacturing center and the Phase One project inNanjing with new production lines. We generated revenues from the manufacture and sale of high-power lithium batteries and raw materials for lithium batteries of$248.7 million and$52.7 million for the fiscal years endedDecember 31, 2022 and 2021, respectively. We incurred a net loss of$11.3 million and a net profit of$61.5 million during the fiscal years endedDecember 31, 2022 and 2021, respectively. New revenues driven from the sale of materials used in manufacturing of lithium batteries, through the newly acquired subsidiary, Hitrans, as well as the continuous climb of sales in uninterruptible supplies and light-electric-vehicle related products, contributed to the total increase. For more details, see "Item 1. Business-Overview of Our Business." Specifically, net revenue from sales of batteries for uninterruptable supplies was$83.6 million for the fiscal year endedDecember 31, 2022 , as compared to$33.3 million for fiscal year endedDecember 31, 2021 , an increase of$50.3 million , or 151%. Net revenue from sales of cathode materials and precursors was$154.0 million for the fiscal year endedDecember 31, 2022 , as compared to$17.9 million for fiscal year endedDecember 31, 2021 . This increase was partly attributed to revenue from Hitrans being included for a full year in 2022, as opposed to only one month in 2021. In addition, net revenues from sales of batteries for light electric vehicles was$6.4 million for the fiscal year endedDecember 31, 2022 , as compared to$0.7 million for fiscal year endedDecember 31, 2021 , an increase of$5.7 million , or 814%. We believe the government's new energy policies will, in the long run, encourage the production of new energy vehicles, optimize the industry's structure, enhance technical standards and strengthen the industry's competitiveness, which ultimately will foster strategic development of new energy vehicles. In addition, our latest development of 32140 battery and our planned investment in the R&D of Series 46 batteries will help us regain competitiveness in both LEV and EV markets with the appropriate products. With the demand for new energy growing, we are confident in our ability to secure additional orders from the expanding market. We completed the construction of a cylindrical power battery manufacturing plant inDalian which started commercial production inJuly 2015 . We have received and been utilizing most of BAK Tianjin's operating assets relocated to our Dalian facilities, including its machinery and equipment for battery production and battery pack production, customers, management team and technical staff, patents and technologies. We also started construction of ourNanjing facilities in 2020. The construction work is designed to comprise two phases. The first phase project ("Phase One") was put into operation in the second half of 2021. Phase One covers an area of approximately 27,173 square meters. Since the operation of Phase One, we have been steadily increasing its production capacity to 2GWh. We started the construction of the second phase project ("Phase Two") in 2022 and expect to complete the infrastructure of the first 60,494 square meters in the third quarter of 2023 which would be put into operation in the last quarter of 2023. TheNanjing facilities, once fully built, are expected to provide 20 GWh capacity to support our customers' growing demand. In addition to construction, we have also purchased machinery and equipment for our capacity expansion. Moreover, given the equity and debt financings we have obtained, we believe that with the booming future market demand for high power lithium-ion products, we can continue as a going concern and return to profitability. In addition, we completed the acquisition of 81.56% of registered equity interests (representing 75.57% of paid-up capital) in Hitrans, a leading developer and manufacturer of NCM precursor and cathode materials inChina , inNovember 2021 . As ofDecember 31, 2022 , our equity interests in Hitrans had reduced to 67.33% after Hitrans took investments from several investors. See "Item 1. Business-Overview of Our Business-Acquisition of A Raw Materials Manufacturer" for more information on the acquisition. The consolidated financial statements contained in this annual report have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty related to our ability to continue as a going concern. 34
Financial Statement Presentation
Net revenues. The Company recognizes revenues when its customer obtains control of promised goods or services, in an amount that reflects the consideration which it expects to receive in exchange for those goods.

This was partly because our batteries now have improved features and higher quality, making them more attractive to electric vehicle manufacturers. Additionally, the downstream market for electric vehicles continued to grow in 2022, leading to an increase in demand for EV battery products. As a result, we were able to secure more orders and increase our
sales volume. 36 Net revenues from sales of batteries for light electric vehicles was approximately$6.4 million for the fiscal year endedDecember 31, 2022 , as compared$0.7 million for 2021, representing an increase of$5.7 million , or 775%. The light electric vehicle market experienced strong growth in 2022 due to various developments. First, the upgrading of electric bicycles to comply with new "national standards" inChina led to increased demand for our batteries. Second, the COVID-19 pandemic spurred a fast development of the food delivery industry, which in turn drove the growth of the shared electric bicycle market. Last, there has been an increased popularity of electric scooters, motors, and bicycles inChina ,Southeast Asia , and European markets as people seek ways to reduce carbon emissions and pollution. With the favorable market conditions, we were able to boost our sales in 2022. We will continue to penetrate the market for batteries used in light electric vehicles. Net revenues from sales of batteries for uninterruptable supplies was$83.6 million for the fiscal year endedDecember 31, 2022 , as compared to$33.3 million for fiscal year endedDecember 31, 2021 , an increase of$50.3 million , or 151%. The increase in sales of batteries for uninterruptable supplies in 2022 can be attributed to a combination of factors including growing demand for renewable energy sources, and our development of reliable and low-cost products. As more businesses and households switch to renewable energy, there has been a growing demand for renewable energy sources and the need for energy storage solutions to support these sources. Additionally, our focus on research and development has allowed us to develop innovative and reliable energy storage products at a competitive pricing. As we continue to invest in R&D and improve our product offerings, we expect to remain a leader in the energy storage industry and see continued growth in sales. Net revenues from trading of raw materials used in lithium batteries were$2,172 for the fiscal year endedDecember 31, 2022 , as compared with$0.5 million
in the same period in 2021. Net revenues from sales of materials for use in manufacturing of lithium battery cell were$154.0 million for the fiscal year endedDecember 31, 2022 , as compared to$17.9 million for 2021. InNovember 2021 , we completed the acquisition of Hitrans, which is a raw materials producer and added the sale of materials for lithium battery cell to our business lines. This increase is partly attributed to the revenue of Hitrans being included for a full year in 2022, as opposed to just one month in 2021. During 2022, we through the newly acquired subsidiary, Hitrans, a producer of cathode and precursor materials, earned sales of materials used in manufacturing of lithium batteries in an amount of$154.0 million . We look forward to strengthening the battery product ecosystem as we seek stable raw material supply and drive greater revenue for our business. Cost of revenues. Cost of revenues increased to$230.6 million for the fiscal year endedDecember 31, 2022 , as compared to$47.6 million for 2021, an increase of$183.1 million , or 385%. The increase in cost of revenues was in line with the increase of net revenues. Included in cost of revenues were write down of obsolete and slow-moving inventories of$1.7 million for the year endedDecember 31, 2022 , while it was$0.9 million for the year 2021. We write down the inventory value whenever there is an indication that it is impaired. Gross profit. Gross profit for the year endedDecember 31, 2022 was$18.1 million , or 7.3% of net revenues as compared to gross profit of$5.1 million , or 9.7% of net revenues, for the fiscal year endedDecember 31, 2021 . Gross profit margin slightly decreased largely due to increased pricing of battery raw materials. Research and development expenses. Research and development expenses increased to$10.6 million for the year endedDecember 31, 2022 , as compared to$5.3 million for 2021, an increase of$5.3 million , or 102%. The increase was primarily attributed to an increase in R&D employees' salaries and social insurance expenses by approximately$2.0 million . R&D employees' salaries and social insurance expenses increased largely due to the inclusion of salaries for the newly acquired subsidiary, Hitrans's, R&D staff, and a growing number of employees at Nanjing CBAK. Also, the expiration of Chinese government's COVID-19 relief policy that alleviated corporations' social insurance burdens has also contributed to the increase. In addition, we incurred expenses for materials used in battery research and development of$0.7 million and$0.5 for the years endedDecember 31, 2022 and 2021, respectively, as a result of the Company's efforts to research and develop upgraded battery products with lower costs and better performance. We incurred$2.7 million of R&D operating expenses by incorporating Hitrans's R&D expenses for the year endedDecember 31, 2022 . Sales and marketing expenses. Sales and marketing expenses slightly decreased to$2.0 million for the year endedDecember 31, 2022 , as compared to$2.3 million for 2021, a decrease of$0.3 million , or 13%. As a percentage of revenues, sales and marketing expenses were 0.8% and 4.4% of revenues for the years endedDecember 31, 2022 and 2021, respectively. For the year endedDecember 31, 2022 , salaries, sales commissions and social insurance expenses for sales and marketing employees increased by approximately$0.5 million . Sales and marketing employees' salaries and social insurance expenses increased is due to a growing number of employees at Nanjing CBAK as well as the expiration of Chinese government's COVID-19 relief policy that alleviated corporations' social insurance burdens. Moreover, given the growth in revenue, we increased sales and marketing employees' salaries and welfare. We incurred exhibition-related expenses of$0.2 million in the year endedDecember 31, 2021 as we attended several exhibitions to increase our brand awareness. We did not attend exhibitions, incurring nil of such expenses, in 2022, largely because of the COVID-19 pandemic and quarantine measures. Besides, the transaction costs and custom declaration charges increased by$0.6 million due to the increase of international sales during fiscal 2022. The above increase was offset by the reversal of our product warranty provision by$1.4 million for the year endedDecember 31, 2022 . We accrues an estimate of the exposures o warranty claims based on current and historical sales data and warranty costs incurred. We have made reversal on product warranty provision on sales which the warranty provision period had passed in 2022. 37 General and administrative expenses. General and administrative expenses slightly decreased to$9.7 million for the year endedDecember 31, 2022 , as compared to$10.0 million for 2021, a decrease of$0.3 million , or 3%. The decrease was primarily resulted from a decrease in professional fees of approximately$1.8 million , offset by an increase in administrative employees' salaries and social insurance expenses by approximately$1.5 million . Administrative employees' salaries and social insurance expenses increased due to the salary expenses incurred for the newly acquired subsidiary, Hitrans, and a growing number of employees at Nanjing CBAK as well as the expiration of Chinese government's COVID-19 relief policy that alleviated corporations' social insurance burdens. Our consultancy, legal and other professional fees decreased by$1.8 million in 2022, as compared to 2021 where we incurred consultancy fees related to the Hitrans acquisition and fundraising activities. Long-lived assets impairment charge.During the course of our strategic review of our operations, we assessed the recoverability of the carrying value of our long-lived assets which resulted in impairment losses of$4.8 million and nil for the years endedDecember 31, 2022 and 2021, respectively. The impairment charge represented the excess of carrying amounts of our long-lived assets over the estimated fair value of the Company's production facilities in Hitrans for the production of materials used in manufacturing of lithium batteries, due to underperformance of Hitrans reporting unit. No impairment charge on production facilities inDalian andNanjing .Goodwill impairment charge.Goodwill impairment was$1.6 million for the year endedDecember 31, 2022 . The impairment loss of goodwill was primarily attributable to the impairment related to Hitrans reporting unit. Hitrans reporting unit carrying value exceeded the fair value as ofDecember 31, 2022 , due to underperformance of Hitrans reporting unit. Recovery of (provision for) doubtful accounts. Provision for doubtful accounts was$0.8 million for the year endedDecember 31, 2022 , as compared to a recovery of$0.8 million for 2021. We determine the allowance based on historical write-off experience, customer specific facts and economic conditions.
Operating loss. As a result of the above, our operating loss totaled
Finance income, net. Finance income, net was$0.5 million for the year endedDecember 31, 2022 , as compared to finance income, net of$0.8 million for the year endedDecember 31, 2021 , as a result of a higher loan balance in 2022. The interest expenses for the year endedDecember 31, 2022 and 2021 was$0.6 million and$0.3 million , respectively.
Other income (expenses), net. Other expenses were
Changes in fair value of warrants liability. We issued warrants in the financings we consummated inDecember 2020 andFebruary 2021 , respectively. We determined that these warrants should be accounted for as derivative liabilities, as the warrants are dominated in a currency (U.S. dollar) other than our functional currency. The change in fair value of warrants liability is mainly due to our share price decline. Income tax credit. Income tax credit was$1.2 million and$7.7 million for the years endedDecember 31, 2022 and 2021, respectively. The decrease in the income tax credit was primarily due to the reduction in the uncertain tax positions taken by the Company in 2021.
Net (loss) income. As a result of the foregoing, we had a net loss of
Liquidity and Capital Resources
We have financed our liquidity requirements from a variety of sources, including short-term bank loans, other short-term loans and bills payable under bank credit agreements, advance from our related and unrelated parties, investors and issuance of capital stock.
We recorded a net loss of$11.3 million in the fiscal year endedDecember 31, 2022 . As ofDecember 31, 2022 , we had cash and cash equivalents and restricted cash of$37.4 million . Our total current assets were$125.7 million and our total current liabilities were$111.9 million , resulting in a net working capital surplus of$13.8 million .

We currently are expanding our product lines and manufacturing capacity in our Dalian andNanjing plants, which require more funding to finance the expansion. We may also require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. We plan to renew our bank loans upon maturity, if required, and plan to raise additional funds through bank borrowings and equity financing in the future to meet our daily cash demands, if required. However, there can be no assurance that we will be successful in obtaining such financing. If our existing cash and bank borrowing are insufficient to meet our requirements, we may seek to sell equity securities, debt securities or borrow from lending institutions. We can make no assurance that financing will be available in the amounts we need or on terms acceptable to us, if at all. The sale of equity securities, including convertible debt securities, would dilute the interests of our current shareholders. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders. If we are unable to obtain additional equity or debt financing as required, our business operations and prospects may suffer.

Critical Accounting Policies and Estimates
Our consolidated financial information has been prepared in accordance withU.S. GAAP, which requires us to make judgments, estimates and assumptions that affect (1) the reported amounts of our assets and liabilities, (2) the disclosure of our contingent assets and liabilities at the end of each fiscal period and (3) the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and reasonable assumptions, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their application. When reviewing our financial statements, the following should also be considered: (1) our selection of critical accounting policies, (2) the judgment and other uncertainties affecting the application of those policies, and (3) the sensitivity of reported results to changes in conditions and assumptions. We believe the following accounting policies involve the most significant judgment and estimates used in the preparation of our financial statements.
We consider the following to be the most critical accounting policies:
Revenue Recognition We recognize revenues when our customer obtains control of promised goods or services, in an amount that reflects the consideration which it expects to receive in exchange for those goods. We recognize revenues following the five step model prescribed under ASU No. 2014-09: (i) identify contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenues when (or as) we satisfy the performance obligation. 45 Revenues from product sales are recognized when the customer obtains control of our product, which occurs at a point in time, typically upon delivery to the customer. We expense incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that it would have recognized is one year or less or the amount is immaterial.
Revenues from product sales are recorded net of reserves established for applicable discounts and allowances that are offered within contracts with our customers.
Product revenue reserves, which are classified as a reduction in product revenues, are generally characterized in the categories: discounts and returns. These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable as the amount is payable to our customer.
Impairment of Long-lived Assets
Long-lived assets, which include property, plant and equipment, prepaid land use rights, leased assets and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Trade and Bills Receivable Trade and bills receivable are recorded at the invoiced amount, net of allowances for doubtful accounts and sales returns. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing trade receivable. We determine the allowance based on historical write-off experience, customer specific facts and economic conditions.
Outstanding trade receivable balances are reviewed individually for collectability. Trade balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
Inventories Inventories are stated at the lower of cost or net realizable value. The cost of inventories is determined using the weighted average cost method, and includes expenditure incurred in acquiring the inventories and bringing them to their existing location and condition. In case of finished goods and work in progress, cost includes an appropriate share of production overhead based on normal operating capacity. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We record adjustments to its inventory for estimated obsolescence or diminution in net realizable value equal to the difference between the cost of the inventory and the estimated net realizable value. At the point of loss recognition, a new cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Warranties We provide a manufacturer's warranty on all our products. We accrue a warranty reserve for the products sold, which includes our best estimate of the projected costs to repair or replace items under warranty. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given our relatively short history of sales of our current products, and changes to our historical or projected warranty experience may cause material changes to the warranty reserve in the future. The portion of the warranty reserve expected to be incurred within the next 12 months is included within accrued liabilities and other while the remaining balance is included within other long-term liabilities on the consolidated balance sheets. 46 Government Grants Our subsidiaries inChina receive government subsidies from local Chinese government agencies in accordance with relevant Chinese government policies. In general, we present the government subsidies received as part of income unless the subsidies received are earmarked to compensate a specific expense, which have been accounted for by offsetting the specific expense, such as research and development expense, interest expenses and removal costs. Unearned government subsidies received are deferred for recognition until the criteria for such recognition could be met.
Grants applicable to land are amortized over the life of the depreciable facilities constructed on it. For research and development expenses, we match and offset the government grants with the expenses of the research and development activities as specified in the grant approval document in the corresponding period when such expenses are incurred.
Share-based Compensation
We adopted the provisions of ASC Topic 718 which requires us to measure and recognize compensation expenses for an award of an equity instrument based on the grant-date fair value. The cost is recognized over the vesting period (or the requisite service period). ASC Topic 718 also requires us to measure the cost of a liability classified award based on its current fair value. The fair value of the award will be remeasured subsequently at each reporting date through the settlement date. Changes in fair value during the requisite service period are recognized as compensation cost over that period. Further, ASC Topic 718 requires us to estimate forfeitures in calculating the expense related
to stock-based compensation.
The fair value of each option award is estimated on the date of grant using the Black-Scholes Option Valuation Model. The expected volatility was based on the historical volatilities of our listed common stocks inthe United States and other relevant market information. We use historical data to estimate share option exercises and employee departure behavior used in the valuation model. The expected terms of share options granted is derived from the output of the option pricing model and represents the period of time that share options granted are expected to be outstanding. Since the share options once exercised will primarily trade in theU.S. capital market, the risk-free rate for periods within the contractual term of the share option is based on theU.S. Treasury yield curve in effect at the time of grant. Warrant Liability For warrants that are not indexed to the Company's stock, the Company records the fair value of the issued warrants as a liability at each balance sheet date and records changes in the estimated fair value as a non-cash gain or loss in the consolidated statement of operations and comprehensive income. The warrant liability is recognized in the balance sheet at the fair value (level 3). The fair value of these warrants has been determined using the Binomial model.

Exchange Rates The financial records of our PRC subsidiaries are maintained in RMB. In order to prepare our financial statements, we have translated amounts in RMB into amounts inU.S. dollars. The amounts of our assets and liabilities on our balance sheets are translated using the closing exchange rate as of the date of the balance sheet. Revenues, expenses, gains and losses are translated using the average exchange rate prevailing during the period covered by such financial statements. Adjustments resulting from the translation, if any, are included in our cumulative other comprehensive income in our stockholders' equity section of our balance sheet. All other amounts that were originally booked in RMB and translated intoU.S. dollars were translated using the closing exchange rate on the date of recognition. Consequently, the exchange rates at which the amounts in those comparisons were computed varied from year to year. The exchange rates used to translate amounts in RMB intoU.S. dollars in connection with the preparation of our financial statements were as follows: RMB per U.S. Dollar Fiscal Year Ended December 31, December 31, 2021 2022 Balance sheet items, except for equity accounts 6.3551 6.9091 Amounts included in the statement of income and comprehensive loss and statement of cash flows 6.4525 6.7264
