GERMANTOWN, Md., Nov. 9, 2022 /PRNewswire/ -- Precigen, Inc. (Nasdaq: PGEN), a biopharmaceutical company specializing in the development of innovative gene and cell therapies to improve the lives of patients, today announced third quarter 2022 financial results and progress of clinical programs.

"Focusing and prioritizing our portfolio has led to rapid progression of our clinical programs. We are exceptionally pleased with the pace and results we are seeing from our portfolio, especially for the PRGN-2012 AdenoVerse Immunotherapy study in RRP, and are excited to showcase data at an investigator-led virtual R&D event in January. We expect the data will make a compelling case for the potential of PRGN-2012 to address the underserved RRP patient population and provide validation for the highly differentiated, first-in-class AdenoVerse therapeutic platform," said Helen Sabzevari, PhD, President and CEO of Precigen. "We also have multiple data presentations at ASH in December, which will highlight continued safety and efficacy of the UltraCAR-T platform."

"Precigen continues to exercise financial prudence and we believe our cash runway is sufficient to advance our clinical priorities into Q4 2023," said Harry Thomasian Jr., CFO of Precigen. "Utilizing proceeds from the sale of Trans Ova, through today, we have been able to retire $144.0 million of the outstanding convertible notes due in July 2023. Retiring this debt, combined with our efforts to streamline and improve our operational efficiencies, further strengthens our financial position and significantly reduces our interest burden through the term of the notes."

Third Quarter 2022 Financial Results Compared to Prior Year Period
Total revenues increased $13.4 million, or greater than 200%, from the quarter ended September 30, 2021. Collaboration and licensing revenues increased $14.5 million compared to the three months ended September 30, 2021, primarily due to the recognition of revenue related to agreements for which revenue was previously deferred, as it became probable that additional performance under the agreements would not be required. Product and service revenues generated by Exemplar decreased $1.1 million from the quarter ended September 30, 2021. Gross margin on products and services declined as a result of the decreased revenues, and increased costs for supplies, drugs, and personnel costs.

Research and development expenses increased $0.2 million, or 2%, from the three months ended September 30, 2021. Contract research organization costs and lab supplies decreased $0.8 million due to timing differences, the completion of our 1b/2a clinical trial of AG019 in the fourth quarter of the prior year, as well as a continued prioritization of clinical product candidates with less expense incurred related to preclinical research programs for the comparable period. This decrease was partially offset with an increase in salaries, benefits, and other personnel costs of $1.0 million primarily due to an increase in the hiring of employees to support the growth of our operations.

SG&A expenses decreased $0.8 million, or 8%, from the three months ended September 30, 2021. Salaries, benefits, and other personnel costs decreased $0.1 million primarily due to reduced head count. Professional fees decreased $0.6 million, primarily due to decreased legal and consulting fees associated with certain matters.

Loss from continuing operations was $7.6 million, or $(0.04) per basic and diluted share, compared to loss from continuing operations of $26.3 million, or $(0.13) per basic and diluted share, in 2021.

First Nine months 2022 Financial Results Compared to Prior Year Period
Total revenues increased $14.6 million, or 138%, from nine months ended September 30, 2021. Collaboration and licensing revenues increased $14.2 million from the nine months ended September 30, 2021, primarily due to the recognition of revenue related to agreements for which revenue was previously deferred, as it became probable that additional performance under the agreements would not be required. Product and service revenues generated by Exemplar increased $0.6 million from the nine months ended September 30, 2021, with that increase occurring earlier in 2022. Gross margin on product and services remained comparable to the prior year as increased revenues were offset by increased costs for supplies, drugs, and personnel costs.

Research and development expenses increased $0.6 million, or 2%, from the nine months ended September 30, 2021. Salaries, benefits, and other personnel costs increased $2.2 million due to an increase in the hiring of employees to support the growth in the Company's development activities. This increase was partially offset with a decrease in contract research organization costs and lab supplies of $1.6 million, primarily due to timing differences, the completion of our 1b/2a clinical trial of AG019 in the fourth quarter of the prior year, as well as a continued prioritization of clinical product candidates with less expense incurred related preclinical research programs for the comparable period.

SG&A expenses decreased $3.7 million, or 9%, from the nine months ended September 30, 2021. Salaries, benefits, and other personnel costs decreased $3.6 million primarily due to $2.6 million reduced stock compensation in 2022 and reduced head count.

Loss from continuing operations was $57.6 million, or $(0.29) per basic and diluted share, compared to loss from continuing operations of $84.1 million, or $(0.43) per basic and diluted share, in 2021.
