#### Chief Executive Officer Appointment
The Board of Directors (the "Board") of the Company appointed Anand Parikh as President and Chief Executive Officer of the Company, effective as of June 13, 2026 (the "Effective Date").

**Anand Parikh** (Age 40) currently serves as the Company's Chief Operating Officer and member of the Board, positions he has held since February 2026. Mr. Parikh previously served as the Chief Executive Officer, Co-Founder and member of the Board of Directors of Faeth Therapeutics, Inc. since its inception in April 2019. Prior to co-founding Faeth, Mr. Parikh served in multiple executive roles at Virta Health beginning in May 2015, including General Counsel, Head of Finance and Head of Human Resources. Mr. Parikh holds a J.D. from New York University School of Law and a B.A. in Political Science from the University of Michigan.

In connection with Mr. Parikh's appointment, the Board approved for Mr. Parikh an annual base salary of $680,000 and a target annual bonus of 60% of his base salary.

As President and Chief Executive Officer, Mr. Parikh is eligible to participate in the Company's Severance and Change in Control Plan ("Severance and CIC Plan") as follows:

Upon a termination by the Company without Cause or a resignation by the participant for Good Reason (in each case, excluding termination due to death or disability) (a "Covered Termination") outside of the period beginning three months prior to and ending twelve months following a Change in Control (a "Change in Control Period"), Mr. Parikh would be entitled to cash severance equal to 12 months of base salary paid in installments over the severance period, plus Company-paid COBRA premiums for up to 12 months, provided that Mr. Parikh is eligible for and timely makes the necessary elections for continuation coverage. Upon a Covered Termination occurring during the Change in Control Period, Mr. Parikh is instead entitled to enhanced cash severance equal to 18 months of base salary paid in a lump sum, a lump-sum bonus payment equal to 1.5x of Mr. Parikh's target annual bonus, Company-paid COBRA premiums for up to 18 months, and full acceleration of all then-outstanding time-based equity awards.

Receipt of benefits under the Severance and CIC Plan is conditioned upon Mr. Parikh's execution of a separation agreement containing a release of claims in favor of the Company, which must become effective within 60 days following the Covered Termination. All payments and severance benefits under the Severance and CIC Plan are subject to the Company's clawback policy.

In connection with Mr. Parikh's appointment as President and Chief Executive Officer, the Board determined that Mr. Parikh will succeed Christopher W. Gerry as the Company's principal executive officer, effective as of the Effective Date. Mr. Gerry will continue to serve as the Company's General Counsel and Corporate Secretary.

Effective as of June 13, 2026, Brian Stephenson was appointed as the Company's Chief Financial Officer and principal financial officer.

As Chief Financial Officer, Mr. Stephenson is eligible to participate in the Severance and CIC Plan as follows:

Upon a Covered Termination outside of a Change in Control Period, Mr. Stephenson would be entitled to cash severance equal to 9 months of base salary paid in installments over the severance period, plus Company-paid COBRA premiums for up to 9 months, provided that Mr. Stephenson is eligible for and timely makes the necessary elections for continuation coverage. Upon a Covered Termination occurring during the Change in Control Period, Mr. Stephenson is instead entitled to enhanced cash severance equal to 12 months of base salary paid in a lump sum, a lump-sum bonus payment equal to 1.0x of Mr. Stephenson's target annual bonus, Company-paid COBRA premiums for up to 12 months, and full acceleration of all then-outstanding time-based equity awards.

Receipt of benefits under the Severance and CIC Plan is conditioned upon Mr. Stephenson's execution of a separation agreement containing a release of claims in favor of the Company, which must become effective within 60 days following the Covered Termination. All payments and severance benefits under the Severance and CIC Plan are subject to the Company's clawback policy.

#### Appointment of Other Officers

#### Resignation of Directors
As previously announced, effective as of June 12, 2026, Christopher W. Gerry, Thomas Ricks and Kristian Humer resigned from the Board. The resignations were not the result of any disagreements with the Company relating to the Company's operations, policies or practices.

As previously announced, effective as of June 12, 2026, Stephen M. Hahn and Saira Ramasastry were appointed to the Board as Class III directors. In connection with their appointments, Mr. Hahn was appointed as a member of the nominating and corporate governance committee, and Ms. Ramasastry was appointed as a member of the audit committee and as a member of the compensation committee.

**Stephen M. Hahn** (Age 66) has served as the Chief Executive Officer of Nucleus RadioPharma, Inc., a radiopharmaceutical contract development and manufacturing organization, since July 2025, and he has served on its board of directors since May 2025.

## Exhibit 99.1

**Exhibit 99.1** 

**Sensei Biotherapeutics Announces Name Change to Faeth Therapeutics, Focused on Advancing PIKTOR, an Oral Therapy Targeting One of the Most Frequently Altered Pathways in Cancer** 

*— Stockholders approved conversion of the Series B preferred stock issued in the February 2026 acquisition of Faeth Therapeutics and concurrent private placement —* 

*— Company changed name to Faeth Therapeutics, Inc. on June 15, 2026; common stock expected to begin trading under the ticker symbol "FTH" on June 16, 2026 —* 

*— Anand Parikh, Faeth co-founder, appointed Chairman, President and Chief Executive Officer; Brian Stephenson, Ph.D., CFA appointed Chief Financial Officer; board strengthened with the addition of former FDA Commissioner Stephen M. Hahn, M.D., and Saira Ramasastry —* 

*— PIKTOR, an investigational all-oral multi-node inhibitor of the PI3K/AKT/mTOR pathway, on track for topline Phase 2 data in advanced endometrial cancer in the second half of 2026 —* 

**AUSTIN, TX — June 15, 2026 —** Sensei Biotherapeutics, Inc. (Nasdaq: SNSE) today announced that it has changed its corporate name to **Faeth Therapeutics, Inc.** (the "Company"). The Company's common stock is expected to begin trading on the Nasdaq Capital Market under the new ticker symbol "**FTH**" on June 16, 2026, and the Company has launched a new corporate website at www.faeththerapeutics.com.

On June 10, 2026, stockholders approved the conversion of the Company's Series B preferred stock issued in connection with the February 2026 acquisition of Faeth Therapeutics and concurrent private placement. As a result, outstanding shares of the Company's Series B convertible preferred stock will automatically convert into common stock effective at 5:00 p.m. ET on June 15, 2026, subject to certain beneficial ownership limitations set by each holder. The Company received approximately $200 million in gross proceeds from the private placement that closed concurrently with its February 2026 acquisition of Faeth.

"Starting tomorrow, we will begin trading on Nasdaq under our new name and ticker as a well-capitalized public company backed by a syndicate of leading life sciences investors, and focused on a clear set of clinical catalysts," said Anand Parikh, Chairman and Chief Executive Officer. "For two decades, drugs that block a single node of the PI3K/AKT/mTOR pathway have been undone by the tumor's ability to route around them. PIKTOR represents our answer to this challenge: an all-oral regimen that patients can take at home, designed to inhibit PI3K-alpha, mTORC1 and mTORC2 at once, close the routes tumors may use to escape, and potentially drive deeper, more durable suppression, with the potential for a best-in-class profile. We believe we now have the capital and the team to put that approach to the test, beginning with topline Phase 2 data in advanced endometrial cancer, expected in the second half of this year, and interim Phase 1b/2 data in HR+/HER2- advanced breast cancer, expected in 2027."

------

**Leadership and Board** 

Effective June 12, 2026, the Company appointed a new executive leadership team. Anand Parikh, a co-founder of Faeth who has led the company since its founding in 2019, has been appointed Chairman, President and Chief Executive Officer. Brian Stephenson, Ph.D., CFA, who previously served as the Company's Head of Operations and Finance and as Chief Financial Officer of BridgeBio Pharma, Inc., has been appointed Chief Financial Officer. Oliver Maddocks, Ph.D., a co-founder of Faeth and a cancer-metabolism researcher, serves as Chief Scientific Officer, and Debbie Chirnomas, M.D., M.P.H., serves as Chief Medical Officer.

The Company's board of directors consists of five members: Anand Parikh (Chair); Bob Holmen; Phillip B. Donenberg; Stephen M. Hahn, M.D.; and Saira Ramasastry. Dr. Hahn, the 24th Commissioner of the U.S. Food and Drug Administration and a former Faeth director, and Ms. Ramasastry, a life sciences strategic advisor and experienced public-company director, joined the board on June 12, 2026.

"In a career spent in oncology and at the FDA, I've learned how rarely a program pairs a high-prevalence target with a potentially differentiated mechanism," said Stephen M. Hahn, M.D., the 24th Commissioner of the U.S. Food and Drug Administration and a member of the Company's board of directors. "I believe Faeth's multi-node, all-oral approach to the PI3K/AKT/mTOR pathway is scientifically rigorous and aimed at a real unmet need. I'm looking forward to guiding the company through this next stage of clinical development."

**About PIKTOR** 

PIKTOR is an investigational, proprietary, all-oral combination of serabelisib, a selective PI3K-alpha inhibitor, and sapanisertib, an mTORC1/mTORC2 inhibitor, designed to inhibit multiple nodes of the PI3K/AKT/mTOR pathway. According to published literature, this pathway is dysregulated in up to 50% of all solid tumors, making it one of the most prevalent therapeutic targets in oncology. PIKTOR is being evaluated in a Phase 2 trial in second-line advanced endometrial cancer (Study FTH-PIK-201), with topline data anticipated in the second half of 2026, and in a Phase 1b/2 trial in HR+/HER2- advanced breast cancer (Study FTH-PIK-101), in which the first patient was dosed in April 2026 and interim data is anticipated in 2027.

**About Faeth Therapeutics** 

Faeth Therapeutics, Inc. (Nasdaq: FTH) is a clinical-stage biotechnology company focused on improving outcomes for cancer patients through multi-node inhibition of critical oncogenic pathways. The Company's lead program is PIKTOR, an investigational all-oral combination of serabelisib and sapanisertib in development for endometrial and breast cancer. Faeth was co-founded in 2019 by Anand Parikh and Oliver Maddocks, Ph.D., together with scientific founders Lewis Cantley, Ph.D., the discoverer of the PI3K pathway; Siddhartha Mukherjee, M.D., D.Phil.; Karen Vousden, Ph.D.; Scott Lowe, Ph.D.; and Greg Hannon, Ph.D. The Company intends to use its website as a means of disclosing material non-public information and for complying with its disclosure obligations under Regulation FD.
