Note Regarding Use of Non-GAAP Financial Measures

In this press release, Instil has presented certain financial information that has not been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). These non-GAAP financial measures include non-GAAP net loss and non-GAAP net loss per share, which are defined as net loss and net loss per share, respectively, excluding non-cash stock-based compensation expense and restructuring and impairment charges. Instil believes that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of Instil’s financial performance. The non-GAAP financial measures are included with the intent of providing investors with a more complete understanding of Instil’s operating results. In addition, these non-GAAP financial measures are among the indicators Instil’s management uses for planning purposes and to measure Instil’s performance. These non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The non-GAAP financial measures used by Instil may be calculated differently from, and therefore may not be comparable to, non-GAAP financial measures used by other companies. Please refer to the below reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures.
