Instil Bio Reports Third Quarter 2022 Financial Results and
Provides Corporate Update

Manufacturing update on voluntary pause of DELTA-1 trial of ITIL-168 in advanced melanoma expected in Q1’23

Reprioritization of resources with enrollment deferred in DELTA-2 trial of ITIL-168

First patient with non-small cell lung cancer dosed with ITIL-306, the first engineered TIL therapy using CoStAR Platform, with plans to share clinical data in 2023

Appointment of cell therapy pioneer Dr. Robert Hawkins as Head of Research and Development, and resignation of Chief Medical Officer, Dr. Zachary Roberts

Company confirms cash runway into 2025 with anticipated sale-leaseback transaction of its Tarzana manufacturing facility

DALLAS, TX, November 14, 2022 (GLOBE NEWSWIRE) Instil Bio, Inc. (“Instil”) (NASDAQ: TIL), a clinical-stage biopharmaceutical company focused on developing tumor infiltrating lymphocyte, or TIL, therapies for the treatment of patients with cancer, today reported its third quarter 2022 financial results and provided a corporate update.

Third Quarter 2022 Highlights and Anticipated Milestones:

DELTA-1 manufacturing and regulatory update: As previously announced, enrollment in DELTA-1 was voluntarily paused following the observation of decreased rates of successful manufacturing of ITIL-168. Our ongoing investigation of the manufacturing failures identified a central source of contamination in the cell media. In conjunction with this pause, we are also evaluating opportunities to increase the robustness of our manufacturing process. In addition, in October 2022, we notified the FDA and other regulatory agencies that an unplanned review of the data for the initial patients that had been dosed with ITIL-168 in the DELTA-1 trial was conducted in order to review risk-benefit. This review was inconclusive because the response data were not mature. Subsequently, the Data Safety Monitoring Board’s prespecified review found no safety concerns. We plan to discuss next steps for the DELTA-1 trial with the FDA and other regulatory agencies, and after such discussions, or as a result of our ongoing investigation of our manufacturing process, we may be required to modify, delay or restart our ITIL-168 clinical development program. We plan to provide an update on our ITIL-168 clinical development program in the first quarter of 2023.

DELTA-2 clinical update: The Company is deferring enrollment in the DELTA-2 study to focus resources toward higher-priority clinical programs.

First patient dosed in Phase 1 dose escalation study of ITIL-306, Instil’s first CoStAR-TIL: Instil recently announced dosing of the first patient with non-small cell lung cancer in the Phase 1 dose escalation study of ITIL-306 for the treatment of multiple solid tumors. The ITIL-306 product contained the target dose of approximately 1 billion CoStAR-TILs in addition to

unmodified TILs. The CoStAR platform introduces a genetic modification which is designed to enhance the activity of TILs within the tumor microenvironment. The Phase 1 trial of ITIL-306 excludes the high-dose interleukin-2 regimen after ITIL-306 infusion. The Company remains committed to the CoStAR platform and expects to report initial clinical data from the trial in 2023.

Appointment of Head of Research and Development: Instil announced the appointment of Robert Hawkins, M.B.B.S., Ph.D., as Head of Research and Development. Dr. Hawkins is a world-renowned oncologist and biotechnology innovator, with a focus on development of novel cell and gene therapies. Dr. Hawkins was the founder and CEO of Immetacyte Ltd., a cell therapy company spun out of the University of Manchester where Dr. Hawkins served as Professor of Medical Oncology. Immetacyte Ltd. generated the foundational TIL technology and clinical data on which Instil was founded.

Resignation of Chief Medical Officer: Instil announced that, pursuant to a separation agreement, Zachary Roberts, M.D., Ph.D., Chief Medical Officer of the Company, has resigned effective November 11, 2022 to pursue other opportunities. The company appreciates Dr. Roberts’ contributions and wishes him the best in his future endeavors.

Company confirms cash-runway into 2025 with anticipated sale-leaseback transaction of its Tarzana manufacturing facility

Third Quarter 2022 Financial and Operating Results:

As of September 30, 2022, we had $303.3 million in total cash and cash equivalents and marketable securities, comprised of $41.1 million in cash and cash equivalents and $262.2 million in marketable securities, compared to $454.1 million in total cash and cash equivalents and marketable securities, comprised of $37.6 million in cash and cash equivalents and $416.5 million in marketable securities as of December 31, 2021. The Company expects that its cash, cash equivalents and marketable securities as of September 30, 2022 will enable it to fund its operating plan into 2025 upon completion of the anticipated sale-leaseback of its Tarzana, CA manufacturing site.

Research and development expenses were $39.7 million and $120.3 million for the three and nine months ended September 30, 2022, respectively, compared to $29.1 million and $64.7 million for the three and nine months ended September 30, 2021, respectively.

General and administrative expenses were $17.0 million and $49.3 million for the three and nine months ended September 30, 2022, respectively, compared to $14.0 million and $37.1 million for the three and nine months ended September 30, 2021, respectively.

Note Regarding Use of Non-GAAP Financial Measures

In this press release, Instil Bio 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. 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 to measure 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.
