On August 25, 2021, and in connection with the closing of the business combination (the "Business Combination"), LWAC was renamed eFFECTOR Therapeutics, Inc. ("eFFECTOR" or the "Company"). All outstanding preferred shares of Old eFFECTOR converted into common shares of Old eFFECTOR on a 1:1 basis, which were then converted, along with all outstanding common shares of Old eFFECTOR, into common shares of the surviving eFFECTOR company through application of an exchange ratio of approximately 0.09657 (the "Exchange Ratio"). The Company is a clinical-stage biopharmaceutical company focused on pioneering the discovery and development of a new class of oncology drugs the Company refers to as selective translation regulator inhibitors. The Company’s principal operations are in the United States, with its headquarters in Solana Beach, California. The Company has devoted substantially all of its resources to raising capital, identifying potential product candidates, establishing its intellectual property portfolio, conducting preclinical studies and clinical trials, establishing arrangements with third parties for the manufacture of its product candidates and related raw materials, and providing general and administrative support for these operations. The Company has not generated revenues from its principal operations through March 31, 2022. Basis of Presentation The accompanying unaudited condensed consolidated financial statements as of March 31, 2022 and for the three months ended March 31, 2022 and 2021 have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to Article 10 of Regulation S-X of the Securities Act of 1933, as amended (the “Securities Act”).

The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, LWAC was treated as the “acquired” Company and eFFECTOR is treated as the acquirer for financial reporting purposes.

The net assets of LWAC are stated at historical cost, with no goodwill or other intangible assets recorded. Old eFFECTOR was determined to be the accounting acquirer based on the following predominant factors: • Old eFFECTOR’s shareholders had a majority of the voting power of the combined company; • the Board and Management were primarily composed of individuals associated with Old eFFECTOR; and • Old eFFECTOR comprised all of the ongoing operations of the combined company. The consolidated assets, liabilities and results of operations prior to the Business Combination are those of Old eFFECTOR.

The accompanying financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that may result from the outcome of this uncertainty. Management is required to perform a two-step analysis over its ability to continue as a going concern. Management must first evaluate whether there are conditions and events that raise substantial doubt about the Company’s ability to continue as a going concern (step 1). If management concludes that substantial doubt is raised, management is also required to consider whether its plans alleviate that doubt (step 2). The Company has experienced net losses and negative cash flows from operating activities since its inception, aside from the years ended December 31, 2021 and December 31, 2020 when net income was realized as a result of a gain on change in fair value recognized associated with the earn-out liability and non-recurring revenue in connection with the Research Collaboration and License Agreement with Pfizer, respectively. The Company has an accumulated deficit of $117.8 million at March 31, 2022. For the three months ended March 31, 2022, the Company used $6.5 million in cash for operations. At March 31, 2022, the Company had cash and cash equivalents of $17.7 million and short-term investments of $28.0 million. The Company anticipates that its expenses will increase significantly in connection with its ongoing activities to support its research and development efforts, and it expects to incur substantial operating losses and negative cash flows from operations for the foreseeable future. The Company believes that its cash and cash equivalents and short-term investments held as of March 31, 2022 are sufficient to fund planned operations for at least twelve months from the date that these financial statements are issued, though the Company may pursue additional cash resources through public or private equity or debt financings. Additionally, in January 2022, the Company entered into an equity purchase agreement with Lincoln Park Capital Fund, LLC ("Lincoln Park"), which included an initial purchase of $3.0 million of shares of common stock and provides for the availability of an additional $47.0 million of shares of its common stock over the thirty-six (36) month term subject to certain conditions (refer to Note 9). Management’s expectations with respect to its ability to fund current planned operations is based on estimates that are subject to risks and uncertainties. Its operating plan may change as a result of many factors currently unknown to management and there can be no assurance that the current operating plan will be achieved in the time frame anticipated by the Company, and it may need to seek additional funds sooner than anticipated. If adequate funds are not available to the Company on a timely basis, management may be required to delay, limit, reduce or terminate certain of its research, product development or future commercialization efforts, obtain funds through arrangements with collaborators on terms unfavorable to the Company, or pursue merger or acquisition strategies, all of which could adversely affect the holdings or the rights of its stockholders.
