Third Quarter 2019 Financial Highlights:

Year-to-Date 2019 Financial Highlights:

“Intrexon’s longstanding focus on Health and, in particular, in cancer therapeutics may be vindicated as Precigen’s clinical programs further develop,” commented Mr. Kirk.

Mr. Kirk concluded, “When I became CEO in 2009, when the company entered into its first collaboration in 2011, when it IPO’d in 2013 and through last year’s reacquisition of the vast majority of its commercial rights pertaining to its cancer therapeutics programs, healthcare has been our greatest area of investment and potential. When Helen Sabzevari joined us in 2017 as President of Precigen, truly the repository of the original Intrexon technology as well as its most substantial technology acquisitions, we saw great potential if these technologies could be unlocked by a great drug development team. Today we begin to share with the world what Helen and her team have accomplished and, equally importantly, to let you hear this formidable pharmaceutical executive tell you this in her own words.”

Third Quarter 2019 Financial Results Compared to Prior Year Period

Total revenues decreased $9.4 million from the quarter ended September 30, 2018. Collaboration and licensing revenues decreased $8.1 million, or 57%, from the quarter ended September 30, 2018 primarily due to the reacquisition of rights previously licensed to some of Intrexon’s most significant collaborators in the second half of 2018 and the result of which eliminated or substantially reduced revenues previously generated from those collaborations. Additionally, collaboration and licensing revenues from collaborations with other collaborators decreased due to lower demand for research and development services in the current year period.

Research and development expenses decreased $13.4 million, or 30%. The 2018 amounts include an $8.7 million expense related to in-process research and development reacquired as part of an asset acquisition in September 2018. Additionally, depreciation and amortization decreased $2.2 million primarily due to intangible assets that were impaired or abandoned in 2018. Selling, general and administrative (SG&A) expenses decreased $14.0 million, or 36%, and of this amount, $11.2 million was primarily attributable to (i) decreased compensation expenses related to performance and retention incentives for SG&A employees and (ii) decreased share-based compensation expense which arose primarily from the departure of former employees during the first half of the current year.

Year-to-Date 2019 Financial Results Compared to Prior Year Period

Total revenues decreased $35.0 million from the nine months ended September 30, 2018. Collaboration and licensing revenues decreased $30.4 million, or 59%, from the nine months ended September 30, 2018 primarily due to the reacquisition of rights previously licensed to some of Intrexon’s most significant collaborators in the second half of 2018 and the result of which eliminated or substantially reduced revenues previously generated from those collaborations. Product revenues decreased $5.0 million, or 21%, primarily due to lower customer demand. Gross margin on products also declined in the current period for the same reason.

Research and development expenses decreased $25.0 million, or 20%. The 2018 amounts include (i) an $8.7 million expense related to in-process research and development reacquired as part of an asset acquisition in September 2018 and (ii) $5.3 million of one-time costs associated with closing one of Oxitec’s research and development facilities as the Company decentralized operations previously conducted in this facility. Additionally, depreciation and amortization decreased $6.5 million primarily due to intangible assets that were impaired or abandoned in 2018. SG&A expenses decreased $33.1 million, or 29%, and of this amount, $26.7 million was primarily attributable to (i) decreased share-based compensation expense which arose primarily from the departure of former employees as well as a result of certain stock option grants becoming fully vested in 2018 and (ii) decreased compensation expenses related to performance and retention incentives for SG&A employees.
