Certain Preliminary Financial Information (Unaudited)

Sana Biotechnology, Inc. (the “Company”) reports that it estimates its cash, cash equivalents, and marketable securities as of July 31, 2025 were approximately $90.1 million.

Additionally, as a result of changes in the Company’s business plans and intention to pursue potential subleases for the Company’s Bothell, Washington and Seattle, Washington facilities, as well as the Company’s decision to suspend further build-out of internal manufacturing capabilities in the near-term at the facility in Bothell due to increased availability of manufacturing capacity at third-party contract development and manufacturing organizations for cell and gene therapy products, as well as progress in understanding the Company’s near-term manufacturing needs, and other factors, the Company determined that a triggering event occurred and performed an impairment analysis in the second quarter of 2025. As of March 31, 2025, leasehold improvements, construction in progress, and operating lease right-of-use assets were $33.3 million, $40.4 million, and $54.8 million, respectively. Based upon preliminary estimates and information available to the Company as of the date of this Current Report on Form 8-K (this “Report”), the Company expects to recognize non-cash impairment losses of approximately $40.0 million to $45.0 million related to the Bothell and Seattle facilities in the month ended May 31, 2025.

These estimates of the Company’s cash, cash equivalents, and marketable securities as of July 31, 2025 and the non-cash impairment losses for the month ended May 31, 2025 are preliminary, have not been audited, are based on information available to the Company as of the filing of this Report, and are subject to change. Additional information and disclosure would be required for a more complete understanding of the Company’s financial position as of July 31, 2025 and for the month ended May 31, 2025. The Company’s independent registered public accounting firm has not audited, reviewed, or performed any procedures with respect to this preliminary information and, accordingly, does not express an opinion or any other form of assurance about it.

Between April 1, 2025 and the date of this Report, the Company sold an aggregate of 7,441,376 shares of its common stock pursuant to its sales agreement dated May 8, 2025 with TD Securities (USA) LLC, as sales agent, in “at-the-market” offerings, for net proceeds of $29.1 million.

Clinical Updates

In June 2025, the Company announced positive six-month results from the UP421 investigator-sponsored trial demonstrating that all primary and secondary endpoints were met. Results of the study through six months after cell transplantation demonstrate the survival and function of pancreatic beta cells as measured by the presence of circulating C-peptide, a biomarker indicating that transplanted beta cells are producing insulin. C-peptide levels also increase with a mixed meal tolerance test during testing at these timepoints, consistent with insulin secretion in response to a meal. 12-week PET-MRI scanning also demonstrated islet cells at the transplant site, a forearm muscle. The study identified no safety issues, and the hypoimmune platform technology (HIP)-modified islet cells evaded immune detection. The trial continues to evaluate safety, persistence, and function of the transplanted cells. On August 4, 2025, the New England Journal of Medicine published a journal article titled “Survival of Transplanted Allogeneic Beta Cells with No Immunosuppression,” which discusses the 12-week results of the trial. In June 2025, the six-month results of the trial were presented at the 85th Annual American Diabetes Association (ADA) Scientific Sessions. The Company and its collaborators at Uppsala University Hospital expect to report additional data from the study, including longer-term follow-up, as the year progresses. In addition, the Company is continuing pre-clinical development of SC451, and a recent FDA INTERACT meeting increases the Company’s confidence in moving forward with its HIP-edited master cell bank for good manufacturing practices (GMP) manufacturing and its non-clinical testing plan.

Personnel Update

Sonja Schrepfer, MD, PhD, the Company’s Senior Vice President and Head of the Hypoimmune Platform, has resigned as an employee to pursue other opportunities.
