Note Regarding Use of Non-GAAP Financial Measures

Instil Bio provides non-GAAP net loss and non-GAAP net loss per share that include adjustments to U.S. Generally Accepted Accounting Principles (GAAP) figures. These adjustments to GAAP net loss exclude non-cash stock-based compensation expense. Instil Bio believes that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of Instil Bio’s financial performance. The non-GAAP financial measures are included with the intent of providing investors with a more complete understanding of Instil Bio’s operating results. In addition, these non-GAAP financial measures are among the indicators Instil Bio’s management uses for planning purposes and measuring Instil Bio’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 Bio may be calculated differently from, and therefore may not be comparable to, non-GAAP financial measures used by other companies. Please refer below for a reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures.
