Autolus Therapeutics plc

Information regarding risks and uncertainties related to our business appears in Part I, Item 1A. “Risk Factors” of our Annual Report. As of the date of this Quarterly Report, there have been no material changes from the risk factors previously disclosed in the Annual Report, except as follows:

We have identified a material weakness in our internal control over financial reporting. This material weakness could continue to adversely affect our ability to report our results of operations and financial condition accurately and in a timely manner.

As a public company, we are subject to the reporting requirements of the Exchange Act, as well as the requirements of the Sarbanes-Oxley Act of 2002, as amended (the "Sarbanes-Oxley Act"), and the listing standards of the Nasdaq Stock Market.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. It also requires management to perform an annual assessment of the effectiveness of our internal control over financial reporting and disclosure of any material weaknesses in such controls. In connection with the audit of our financial statements for the year ended December 31, 2023, we identified a material weakness in our internal control over financial reporting in connection with the historic misinterpretation and application of ASC 740 - Income Taxes, resulting in our UK small and medium enterprise (SME) tax credits being incorrectly presented in income tax benefit (expense). Refer to Note 3, Restatement of Previously Issued Consolidated Financial Statements, in the Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K this report for additional information.

As described below in Part I, Item 4 of this Quarterly Report, in connection with our review procedures for the three months ended March 31, 2024, we identified an additional material weakness due to an insufficiency of controls over complex accounting transactions. The lack of controls did not allow us to identify, understand and evaluate the impact of certain key judgments that arose during the three months ended March 31, 2024 related to the BioNTech Agreements. Our process, as designed, was inadequate to deal with the complexity of the accounting for the transaction and did not allow for an effective and timely evaluation of these matters and their impact on our financial statements.

Any failure to remediate the identified material weaknesses, or to develop or maintain effective controls, or any difficulties encountered in the implementation or improvement of such controls, could harm our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods, such as the restatement of our previously issued consolidated financial statements described in more detail in our most recent Annual Report on Form 10-K.

Any failure to remediate the identified material weaknesses, or to implement and maintain effective internal control over financial reporting also could adversely affect the results of management evaluations and, to the extent they are required in the future, attestations of our independent registered public accounting firm with respect to our internal control over financial reporting. We can provide no assurance that the measures we are taking and plan to take in the future will remediate the material weaknesses described above, or that any additional material weaknesses or restatements of financial results will not arise in the future due to a failure to implement and maintain adequate internal control over financial reporting or circumvention of these controls. In addition, even if we are successful in strengthening our controls and procedures, in the future those controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our financial statements. We continue to evaluate steps to remediate the material weaknesses identified. Any failure to maintain effective internal control over financial reporting could adversely impact our ability to report our financial position and results from operations on a timely and accurate basis. If our financial statements are not accurate, investors may not have a complete understanding of our operations. Likewise, if our financial statements are not filed on a timely basis, we could be subject to sanctions or investigations by the Nasdaq, the SEC or other regulatory authorities, or other potential claims or litigation. Ineffective internal control over financial reporting could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our ADSs.

Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in our reported financial and other information, which may have a negative effect on the trading price of our ADSs. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the Nasdaq Global Select Market.
