Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with available financial resources from the Revolving Facility, will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve Various factors can affect the Company’s liquidity, including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry, the conversion of design opportunities into revenue, market acceptance of existing and new products including solutions based on its eFPGA IP, ArcticLink ® ® S3 Over the longer term, the Company anticipates that sales generated from its new product offerings and existing cash and cash equivalents, together with financial resources from its Revolving Facility, assuming renewal of the Revolving Facility or the Company entering into a new debt agreement with an alternative lender prior to the expiration of the Revolving Facility in December 2023, Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of QuickLogic and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated. Foreign Currency The functional currency of the Company's non-U.S. operations is the U.S. dollar.

Uses of Estimates The preparation of these unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the period. Actual results could differ materially from those estimates, particularly in relation to revenue recognition, the allowance for doubtful accounts, sales returns, valuation of long-lived assets including mask sets, valuation of goodwill, capitalized internal-use software and related amortizable lives, fair value measurements, and intangibles related to the acquisition of SensiML, including the estimated useful lives of acquired intangible assets, valuation of inventories including identification of excess quantities, market value and obsolescence, measurement of stock-based compensation awards, accounting for income taxes and estimating accrued liabilities.
