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 2021, we added a production line to produce electric bicycles, in light of the great potential for growth in this market. As of the date of this report, this production line has not commenced commercial production. We generated revenues from the manufacture and sale of high-power lithium batteries and raw materials for lithium batteries of$52.7 million and$37.6 million for the fiscal years endedDecember 31, 2021 and 2020, respectively. We incurred a net profit of$61.5 million and a net loss of$7.8 million during the fiscal years endedDecember 31, 2021 and 2020, respectively. Our revenues in relation to electric vehicles are, to some extent, adversely impacted by the reduction of government subsidies to new energy vehicles. However, 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 increase. For more details, see "Item 1. Business-Overview of Our Business." Accordingly, net revenues from sales of batteries for uninterruptable supplies was$33.3 million for the fiscal year endedDecember 31, 2021 , as compared to$22.7 million for fiscal year endedDecember 31, 2020 , an increase of$10.6 million , or 47%. Net revenue from trading of raw materials for lithium batteries was$0.5 million for the fiscal year endedDecember 31, 2021 , as compared to$14.5 million for fiscal year endedDecember 31, 2020 , a decrease of$14.0 million , or 96%. Net revenue from sales of cathode materials and precursors was$17.9 million for the fiscal year endedDecember 31, 2021 , as compared to nil for fiscal year endedDecember 31, 2020 . With the announced ultra-low-temperature battery technology, we believe that our revenues in the energy storage market will continue to grow. In addition, net revenues from sales of batteries for light electric vehicles was$0.5 million for the fiscal year endedDecember 31, 2021 , as compared to$39,428 for fiscal year endedDecember 31, 2020 , an increase of$0.5 million , or 1,218%. We believe the government policies relating to new energy will in the long term encourage the production of new energy vehicles, optimize the structure of the new energy vehicles industry, enhance technical standards of the industry and strengthen its core competitiveness, which ultimately would foster strategic development of the new energy vehicles. In addition, our latest development of 32140 battery and our planned investment in the R&D of 46800 battery will help us regain competitiveness in both LEV/EV markets with the appropriate products. Therefore, the demand for new energy likely will grow in the future and we will be able to secure more potential orders from the new energy market. We have completed the construction of a cylindrical power battery manufacturing plant and a power battery packing plant of our Dalian facilities 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 the investments in and construction of ourNanjing facilities, which is designed to comprise of two phases. The first phase is in the process of interior renovation and equipment purchase. Phase One has an area of approximately 10,000 square meters at nearly no cost due to the government's low rentals. Phase Two is currently under construction design. TheNanjing facilities, once built, are expected to provide 18GWh capacity to support our demand. We have also purchased machinery and equipment to expand our manufacturing capabilities. Moreover, given the equity and debt financings we have obtained recently, 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 . 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. 41

In addition, we issued to the investors (i) in a concurrent private placement, the Series A-1 warrants to purchase a total of 4,469,988 shares of common stock, at a per share exercise price of$7.67 and exercisable for 42 months from the date of issuance; (ii) in the registered direct offering, the Series B warrants to purchase a total of 4,469,988 shares of common stock, at a per share exercise price of$7.83 and exercisable for 90 days from the date of issuance; and (iii) in the registered direct offering, the Series A-2 warrants to purchase up to 2,234,992 shares of common stock, at a per share exercise price of$7.67 and exercisable for 45 months from the date of issuance.

As ofAugust 31, 2021 , we had not received any notices from the investors to exercise Series B warrants. As of the date of this report, Series B warrants, along with Series A-2 warrants, had both expired. 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. The following table sets forth a summary of our cash flows for the periods indicated: (All amounts in thousands of U.S. dollars) Year Ended December 31, December 31, 2020 2021 Net cash used in operating activities$ (5,097 ) $ (4,270 ) Net cash used in investing activities (5,710 ) (38,081 ) Net cash provided by financing activities 25,827 48,272

Critical Accounting Policies
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. 52 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. 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 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 Accounts and Bills Receivable
Trade accounts 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 accounts receivable. We determine the allowance based on historical write-off experience, customer specific facts and economic conditions.
Outstanding accounts receivable balances are reviewed individually for collectability. Account 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. 53 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 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.
Changes in Accounting Standards
Please refer to note 2 to our consolidated financial statements, "Summary of Significant Accounting Policies and Practices-Recently Adopted Accounting Standards," for a discussion of relevant pronouncements.
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, 2020 2021 Balance sheet items, except for equity accounts 6.5286 6.3551 Amounts included in the statement of income and comprehensive loss and statement of cash flows 6.9032 6.4525
