Nature And Continuance Of Operations
Nature and Continuance of Operations	1. Nature and Continuance of Operations Standard Lithium Ltd. (the “Company”) was incorporated under the laws of the Province of British Columbia on August 14, 1998 under the name Tango Capital Corp. On April 7, 1999, the Company changed its name to Patriot Capital Corp. and to Patriot Petroleum Corp. effective March 5, 2002. On December 1, 2016 the Company continued under the Canadian Business Corporations Act and changed its name to Standard Lithium Ltd. The Company’s principal operations are comprised of exploration for and development of lithium brine properties in the United States of America (“USA”). The address of the Company’s corporate office and principal place of business is 110 The condensed consolidated interim financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) on a going concern basis, which presume the realization of assets and discharge of liabilities in the normal course of business for the foreseeable future. The Company has no sources of revenue and as at March 31, 2022 had an accumulated deficit of $100,285,384 (June 30, 2021 - $68,617,507). These matters raise significant doubt regarding the Company’s ability to continue as a going concern. The Company’s ability to continue as a going concern is dependent upon its ability to raise equity financings. These condensed consolidated interim financial statements do not include any adjustments to the amounts and classification of assets and liabilities that might be necessary should the Company be unable to continue in business. During March 2020, the World Health Organisation declared COVID-19 a global pandemic. This contagious disease outbreak and any related adverse developments, has adversely affected workforces, economies and financial markets globally, leading to an economic downturn. The impact of COVID-19 on the Company’s operations has not been significant, but management continues to monitor the situation. On January 27, 2022, a putative securities class action lawsuit was filed against the Company, Robert Mintak, and Kara Norman in the United States District Court for the Eastern District of New York, captioned Gloster v. Standard Lithium Ltd., et al., 22-cv-0507 (E.D.N.Y.) (the “Action”). The complaint seeks to certify a class of investors who purchased or otherwise acquired the Company’s publicly traded securities between May 19, 2020 and November 17, 2021, and asserts violations of Section 10(b) of the Securities Exchange Act of 1934 (“Exchange Act”) against all defendants and Section 20(a) of the Exchange Act against the individually-named defendants. The complaint alleges, among other things, that during the proposed class period, defendants misrepresented and/or failed to disclose certain material facts regarding the Company’s LiSTR Direct Lithium Extraction (“LiSTR”) technology and “final product lithium recovery percentage” at its Direct Lithium Extraction Demonstration Plant in southern Arkansas. Plaintiff seeks various forms of relief, including monetary damages in an unspecified amount. The Company intends to vigorously defend against the Action.

The Loan will be convertible at the option of the Lender at any time prior to the repayment of the Loan, at the Lender’s option, to convert all or any portion of a Loan into common shares and warrants The outstanding principal amount of the Loan will bear interest at an annual rate of 3.0%, subject to adjustments with accrued interest being payable in cash on each anniversary of the Closing Date. In the event that the Company has a positive consolidated operating cash flow, as shown on its consolidated financial statements, the Company will pay a fee to the Lender of 4.5% per annum on the average daily outstanding principal amount of the Loan from the issuance date to the date that the consolidated operating cash flow of the Company is positive.

The Company’s risk management policies are established to identify and analyze the risks faced by the Company, to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and in response to the Company’s activities. Management regularly monitors compliance with the Company’s risk management policies and procedures and reviews the adequacy of the risk management framework in relation to the risks faced by the Company. ​ ​ 14. Financial Instruments and Financial Risk Management – continued ​ In the normal course of operations, the Company is exposed to various risks such as commodity, interest rate, credit, and liquidity risk. To manage these risks, management determines what activities must be undertaken to minimize potential exposure to risks. The objectives of the Company in managing risk are as follows: ● maintaining sound financial condition; ● financing operations; and ● ensuring liquidity to all operations. In order to satisfy these objectives, the Company has adopted the following policies: ● recognize and observe the extent of operating risk within the business; ● identify the magnitude of the impact of market risk factors on the overall risk of the business and take advantage of natural risk reductions that arise from these relationships. ​ (i) Interest rate risk The Company does not have any financial instruments which are subject to interest rate risk. (ii) Credit risk Credit risk is the risk of loss if counterparties do not fulfill their contractual obligations and arises principally from trade receivables. The Company does not have any financial instruments which are subject to credit risk. (iii) Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. The Company manages this risk by careful management of its working capital to ensure its expenditures will not exceed available resources. At March 31, 2022, the Company has a working capital surplus of $134,622,212 . (iv) Currency risk Currency risk is the risk to the Company’s earnings that arises from fluctuations of foreign exchange rates and the degree of volatility of these rates. The Company does not use derivative instruments to reduce its exposure to foreign currency risk. The Company is exposed to currency risk through the following assets and liabilities denominated in US dollars: ​ ​ ​ ​ ​ ​ ​ March 31, 2022 June 30, 2021 Cash ​ 113,997,420 736,623 Accounts payable ​ (2,450,239) (1,520,823) ​ At March 31, 2022, US Dollar amounts were converted at a rate of USD 1.00 to CAD 1.2496. A 10% increase or decrease in the US Dollar relative to the Canadian Dollar would result in a change of approximately $11,155,000 in the Company’s comprehensive loss for the year to date.
