AgeX Therapeutics Reports First Quarter 2023 Financial Results

ALAMEDA, Calif.—(BUSINESS WIRE)—May 12, 2023—AgeX Therapeutics, Inc. (“AgeX”; NYSE American: AGE), a biotechnology company developing therapeutics for human aging and regeneration, reported its financial and operating results for quarter ended March 31, 2023.

Balance Sheet Information

Cash, cash equivalents, and restricted cash totaled $0.3 million as of March 31, 2023. As of March 31, 2023, AgeX owed Juvenescence Limited $33.6 million in principal and origination fees on account of loans extended to AgeX.

Increase in Secured Note Line of Credit

On May 9, 2023, AgeX and Juvenescence entered into a second amendment to an Amended and Restated Secured Convertible Promissory Note (the “Secured Note”) to increase the amount of the line of credit available to AgeX by $4,000,000, subject to the terms of the Secured Note and Juvenescence’s discretion to approve and fund each of AgeX’s future draws of that additional amount of credit.

First Quarter 2023 Operating Results

Revenues: Total Revenues for the first quarter of 2023 were $10,000 as compared with $5,000 in the same period in 2022. Revenues are entirely comprised of sales of research products including stem cell products.

Operating expenses: Operating expenses for the three months ended March 31, 2023 were $2.2 million, as compared with $2.1 million for the same period in 2022.

Research and development expenses for the three months ended March 31, 2023 decreased by approximately $0.2 million to $0.2 million from $0.4 million during the same period in 2022. The net decrease was primarily attributable to reductions of $0.1 million in salaries to employees and related payroll related expenses, including noncash stock-based compensation expense, and general laboratory supplies and expenses, and $0.1 million in outside research and services allocable to research and development expenses.

General and administrative expenses for the three months ended March 31, 2023 increased by $0.3 million to $2.0 million as compared to $1.7 million during the same period in 2022. The net increase is attributable to increases of $0.5 million in professional fees for legal services and consulting expenses incurred in connection with due diligence and other expenses related to the possible merger between AgeX and Serina Therapeutics Inc., an Alabama corporation (“Serina”), and $0.1 million in professional fees for other non-recurring legal services. These increases were offset to some extent by a $0.2 million decrease in noncash stock-based compensation to employees, consultants and directors, and $0.1 million in patent and license maintenance related fees.

Other expense, net: Net other expense for the three months ended March 31, 2023 is comprised of $1.1 million amortization of deferred debt issuance costs and other debt related expenses included in interest expense and $30,000 unrealized loss on change in fair value of warrants issued to Juvenescence in connection with borrowings under loans from Juvenescence.

Net loss attributable to AgeX: The net loss attributable to AgeX for the three months ended March 31, 2023 was $3.3 million, or ($0.09) per share (basic and diluted) compared to $2.7 million, or ($0.07) per share (basic and diluted), for 2022. Increased net loss attributable to AgeX for the three months ended March 31, 2023 as compared to 2022 is largely attributable to expenses related to the possible merger between AgeX and Serina incurred in 2023 and increased amortization of deferred debt costs on loans from Juvenescence.

Going Concern Considerations

As required under Accounting Standards Update 2014-15, Presentation of Financial Statements-Going Concern (ASC 205-40), AgeX evaluates whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date its financial statements are issued. Based on AgeX’s most recent projected cash flows, AgeX believes that its cash and cash equivalents and available sources of debt and equity capital including the loan facilities provided by Juvenescence to advance up to an additional $4 million to AgeX as of May 9, 2023 would not be sufficient to satisfy AgeX’s anticipated operating and other funding requirements for the twelve months following the filing of AgeX’s Quarterly Report on Form 10-Q for the three months ended March 31, 2023. These factors raise substantial doubt regarding the ability of AgeX to continue as a going concern.
