BRISBANE, Calif.--(BUSINESS WIRE)-- Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicines company, today announced recent business highlights, including progress on its strategic transformation and a corresponding restructuring of operations and workforce reduction, and reported third quarter 2023 financial results.

“In 2020, we shared our refreshed company strategy which aims to both maximize the potential of our proprietary genomic editing and delivery technology, and to focus on areas where we believe we can apply that technology to be either first-in-class or best-in-class. The process of streamlining Sangamo’s pipeline has been accelerated within today’s challenging economic environment and we have had to make difficult decisions to defer further investments and seek collaboration partners or direct investment in both our Fabry gene therapy and CAR-Treg cell therapy programs,” said Sandy Macrae, Chief Executive Officer of Sangamo. “As we work to unlock value in our clinical programs that is not currently reflected as part of Sangamo, we plan to do everything in our power to get these important assets into the hands of parties with the means to advance them towards patients. At the same time, we will continue to progress our promising epigenetic regulation programs for neurological diseases and hope to soon share a breakthrough in our capsid delivery capabilities, which we believe could open the door for many other high-value and unmet diseases to be addressed with our editing capabilities. We continue to seek ways to raise additional capital to strengthen our financial foundation.”

The restructuring announced today represents a further step towards simplifying the Sangamo organization and focusing on our epigenetic regulation therapies treating neurological diseases and our novel AAV capsid delivery technologies. Sangamo is deferring new investments in its Fabry and CAR-Treg programs beyond what is currently committed and is actively seeking collaboration partners or direct investors in both. In addition, Sangamo expects to close its Brisbane, California facility in early 2024 to conserve cash resources, and will transition its headquarters to its Richmond, California facility as of January 1, 2024. As a result of this restructuring, Sangamo is reducing its US workforce by approximately 40%, or approximately 162 roles.

In connection with the restructuring, D. Mark McClung, Executive Vice President, Chief Operating Officer and Jason Fontenot, Senior Vice President, Chief Scientific Officer will be leaving the company on January 2, 2024. In the context of a streamlined and more focused organization, we are eliminating their roles. Until his departure, Mark will continue to lead our search for partners and investors in our Fabry and CAR-Treg programs. Amy Pooler, currently serving as Vice President, Neuroscience and Gregory Davis, currently serving as Vice President, Genome Engineering Design and Technology, have been appointed as Head of Research and Head of Technology, respectively, effective November 17, 2023.

The restructuring and workforce reductions, in combination with other potential cost reductions, are anticipated to reduce our non-GAAP annual operating expenses from approximately $240 million-$260 million in 2023 to approximately $115 million-$135 million in 2024, a decrease of approximately 50%. Sangamo expects to incur approximately $8 million-$10 million in one-time restructuring costs in the fourth quarter of 2023. Sangamo believes its cash, cash equivalents, and marketable securities as of September 30, 2023, in combination with the cost savings expected from the restructuring, workforce reduction and other potential cost reductions, will be sufficient to fund its planned operations into the third quarter of 2024.

Dr. Macrae continued: “I am grateful to all our employees for their commitment to Sangamo’s mission and the patients we seek to serve, and have special appreciation to all those who are leaving for their important contributions. Additionally, I would like to personally thank Mark for the wisdom, candor and leadership he has brought to Sangamo. He has been a trusted colleague and will be greatly missed. I would also like to thank Jason for his dedication, passion and leadership. He leaves a strong scientific legacy for which we will always be grateful.”

Third Quarter 2023 Financial Results

Consolidated net loss for the third quarter ended September 30, 2023 was $104.2 million, or $0.59 per share, compared to a net loss of $53.2 million, or $0.34 per share, for the same period in 2022, primarily due to a non-cash charge relating to impairment of long-lived asset of $44.8 million, which was a result of continued decline in our stock price and related market capitalization, initiation of actions to seek external financing and reprioritize certain research and development programs, and continued decline in equity values in the biotechnology industry.

Revenues

Revenues for the third quarter ended September 30, 2023 were $9.4 million, compared to $26.5 million for the same period in 2022.

The decrease of $17.1 million in revenues was primarily attributed to a decrease of $9.6 million and $9.1 million in revenue relating to our collaboration agreements with Novartis and Biogen, respectively, due to the termination of these collaboration agreements in June 2023, and a decrease of $1.4 million in revenue relating to our collaboration agreement with Kite, reflecting a reduction in collaboration activities during the quarter. These decreases were partially offset by an increase of $3.0 million in revenue relating to our other license agreements.

GAAP and Non-GAAP Operating Expenses

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
(In millions)			2023				2022				2023				2022
Research and development		$	57.1			$	65.1			$	183.4			$	183.7
General and administrative			13.9				16.2				48.1				46.2
Impairment of goodwill and indefinite-lived intangible assets			-				-				89.5				-
Impairment of long-lived assets			44.8				-				65.2				-
Total operating expenses			115.8				81.3				386.2				229.9
Impairment of goodwill and indefinite-lived intangible assets			-				-				(89.5	)			-
Impairment of long-lived assets			(44.8	)			-				(65.2	)			-
Stock-based compensation expense			(6.2	)			(7.8	)			(21.3	)			(23.4	)
Non-GAAP operating expenses		$	64.8			$	73.5			$	210.2			$	206.5

Total operating expenses on a GAAP basis for the third quarter ended September 30, 2023 were $115.8 million, compared to $81.3 million for the same period in 2022. GAAP operating expenses for the third quarter ended September 30, 2023 included a non-cash charge relating to impairment of long-lived asset of $44.8 million, as described above. Non-GAAP operating expenses, which exclude impairment charges and stock-based compensation expense, for the third quarter ended September 30, 2023 were $64.8 million, compared to $73.5 million for the same period in 2022.

The decrease in total operating expenses on a non-GAAP basis was primarily attributable to lower compensation and other personnel costs mainly due to lower headcount as a result of restructuring of operations and corresponding reduction in workforce announced in April 2023, and decrease in manufacturing and lab supply expenses due to deferral and reprioritization of certain research and development programs. These decreases were partially offset by higher facilities and infrastructure related costs, and higher external expenses as we advance our clinical and preclinical pipeline.

Cash, Cash Equivalents and Marketable Securities

Cash, cash equivalents and marketable securities as of September 30, 2023 were $132.1 million, compared to $307.5 million as of December 31, 2022. As of September 30, 2023, we have raised approximately $15.1 million in net proceeds under our at-the-market offering program since January 1, 2023. We believe that our available cash, cash equivalents and marketable securities as of September 30, 2023, in combination with the cost savings expected from the restructuring, workforce reduction and other potential cost reductions, will be sufficient to fund our planned operations into the third quarter of 2024.

Updated Financial Guidance for 2023

• GAAP operating expenses, including impairment of goodwill, indefinite-lived intangible assets, and long-lived assets, and stock-based compensation expense, for the full year 2023 are now estimated to be in the range of approximately $422 million to $442 million, reflecting the additional non-cash impairment charges recorded in the third quarter. The previous GAAP operating expenses guidance provided on August 8, 2023 was in the range of approximately $378 million to $398 million.
• We continue to estimate non-GAAP operating expenses to be in the range of approximately $240 million to $260 million, which remains unchanged from the last update on April 26, 2023. Estimated non-GAAP operating expenses exclude impairment of goodwill of $38.1 million, impairment of indefinite-lived intangible assets of $51.3 million, impairment of long-lived assets of $65.2 million, and stock-based compensation expense of $28.0 million.

These statements are not guarantees of future performance and are subject to certain risks and uncertainties that are difficult to predict. Factors that could cause actual results to differ include, but are not limited to, risks and uncertainties related to Sangamo’s ability to execute its strategic prioritization and restructuring as currently contemplated; the actual charges associated with the restructuring being higher than anticipated or changes to the assumptions on which the estimated charges associated with the restructuring are based; Sangamo’s ability to achieve projected cost savings in connection with the restructuring and to further reduce operating expenses; unintended consequences from the restructuring that impact Sangamo’s business; our lack of capital resources to fully develop, obtain regulatory approval for and commercialize our product candidates, including our ability to secure the funding required to initiate a potential Phase 3 trial of isaralgagene civaparvovec in a timely manner or at all; our need for substantial additional funding to execute our operating plan and to continue to operate as a going concern; the potential of our preclinical programs utilizing zinc finger technology to address neurological health disorders; the effects of macroeconomic factors or financial challenges, including as a result of the ongoing overseas conflict, current or potential future bank failures, inflation and rising interest rates, on the global business environment, healthcare systems and business and operations of Sangamo and our collaborators, including the initiation and operation of clinical trials; the research and development process, including the enrollment, operation and results of clinical trials and the presentation of clinical data; the impacts of clinical trial delays, pauses and holds on clinical trial timelines and commercialization of product candidates; the uncertain timing and unpredictable nature of clinical trial results, including the risk that therapeutic effects in the Phase 3 AFFINE trial will not be durable in patients as well as the risk that the therapeutic effects observed in the latest preliminary clinical data from the Phase 1/2 STAAR study will not be durable in patients and that final clinical trial data from the study will not validate the safety and efficacy of isaralgagene civaparvovec, and that the patients withdrawn from ERT will remain off ERT; the unpredictable regulatory approval process for product candidates across multiple regulatory authorities; reliance on results of early clinical trials, which results are not necessarily predictive of future clinical trial results, including the results of any Phase 3 trial of our product candidates; the potential for technological developments that obviate technologies used by Sangamo; our reliance on collaborators and our potential inability to secure additional collaborations, and our ability to achieve expected future financial performance.

There can be no assurance that we and our collaborators will be able to develop commercially viable products. Actual results may differ materially from those projected in these forward-looking statements due to the risks and uncertainties described above and other risks and uncertainties that exist in the operations and business environments of Sangamo and our collaborators. These risks and uncertainties are described more fully in our Securities and Exchange Commission, or SEC, filings and reports, including in our Annual Report on Form 10-K for the year ended December 31, 2022, as supplemented by our Quarterly Report on Form 10-Q for the quarter ended September 30, 2023 to be filed with the SEC, and future filings and reports that Sangamo makes from time to time with the SEC. Forward-looking statements contained in this announcement are made as of this date, and we undertake no duty to update such information except as required under applicable law.

Non-GAAP Financial Measures

To supplement our financial results and guidance presented in accordance with GAAP, we present non-GAAP operating expenses, which excludes stock-based compensation expense and impairment of goodwill, indefinite-lived intangible assets and long-lived assets from GAAP operating expenses. We believe that this non-GAAP financial measure, when considered together with our financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare our results from period to period and to our forward-looking guidance, and to identify operating trends in our business. We have excluded stock-based compensation expense because it is a non-cash expense that may vary significantly from period to period as a result of changes not directly or immediately related to the operational performance for the periods presented, and we have excluded impairment of goodwill, indefinite-lived intangible assets and long-lived assets to facilitate a more meaningful evaluation of our current operating performance and comparisons to our operating performance in other periods. This non-GAAP financial measure is in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. We encourage investors to carefully consider our results under GAAP, as well as our supplemental non-GAAP financial information, to more fully understand our business.
