Robert Shapiro, lead independent board member of Intrexon commented, Today s announced actions mark important steps toward Intrexon becoming a

dedicated healthcare company advancing technologies and products that address complex healthcare challenges. Thanks to RJ s vision and Dr. Sabzevari s strong execution and leadership, our healthcare business has made great progress

and the board is confident of the company s future prospects as a healthcare-focused company led by Helen, whom we have come to know as a highly strategic, driven and results-oriented leader. Simultaneously, following a thorough evaluation of

strategic alternatives for our non-healthcare businesses, we have found excellent counterparties to take these businesses forward, thus providing a significant cash runway in line with our previously stated

objective, concluded Mr. Shapiro.

It has been a great honor to serve as Intrexon s CEO, stated Mr. Kirk. There never

has been a more exciting time in healthcare, and I know that Dr. Sabzevari has the vision, drive and commitment to lead the new Precigen into the future to continue advancement of its robust pipeline. Moreover, with its additional support for

its cash runway, its budgeted outlay significantly reduced and the present state of its clinical and preclinical pipeline, it is an appropriate time for the company to institute a leadership change, especially at this time in favor of Helen. Aside

from being the finest drug developer I have met, Helen demonstrated to all of us her tremendous managerial and leadership skills. While I intend on staying close in my role as Executive Chairman, my confidence in Helen is enormous, and I believe

that her leadership of the company will reward all of us who have contributed to and believed in Intrexon over the years.

joined Intrexon in 2017 and has served as President of Precigen for the past two years, brings extensive expertise in the research and development of immunotherapies as well as

experience translating novel treatments from preclinical stage into the clinic. Under Dr. Sabzevari s leadership, the healthcare-focused organization will seek to improve patients

lives with novel therapies that harness transformational approaches in gene and cell therapies, microbe-based biotherapeutics, and regenerative medicine.

I am honored to work with our highly experienced board and talented healthcare teams to advance our portfolio of clinical and preclinical assets that we

believe will deliver significantly better options to patients and solve unmet needs in healthcare, said Dr. Sabzevari. I would like to thank RJ for his leadership in assembling a world-class platform of innovative biotechnologies

that has laid the foundation for a focused pipeline of precision medicines which I believe have a high probability of success. We look forward to building value for all of our stakeholders in the coming years as we bring life-changing medicines to

Intrexon Sale of Certain Non-healthcare Assets

Intrexon has signed definitive agreements to sell certain of its other non-healthcare assets to Third Security, LLC, a venture capital firm that invests in high-growth technology-driven businesses and is led by Intrexon Executive Chairman, Randal J. Kirk, for $53M in cash plus

the contingent right to receive certain additional amounts that Third Security may earn from these assets after closing. In addition, Third Security has agreed to purchase from the company $35M of shares of Intrexon s common stock. Under the

terms of the agreement, Third Security will purchase the Ag Biotech Division (AgBio), Intrexon Laboratories Hungary (ILH), Intrexon Produce Holdings, Inc. (owner of Okanagan Specialty Fruits), Intrexon UK Holdings, Inc. (owner of Oxitec, Ltd.),

Intrexon s nominal equity interests in Oragenics and Surterra, and the internet domain name DNA.com.

The transactions with Third Security are

expected to close on January 31, 2020, pending the expiration of a go-shop period during which Intrexon will continue to market these assets to third parties. Intrexon has the ability to terminate the

agreement with Third Security to accept a higher bid. A special committee composed of independent members of Intrexon s Board of Directors, following a process over several months to consider various strategic alternatives for Intrexon s non-core assets, and advised by independent financial and legal advisors, unanimously recommended to Intrexon s Board the approval of the agreement.

Intrexon has entered into an agreement to sell its interest in EnviroFlight, LLC, to Darling Ingredients, Inc. for $12.2M in cash and expects to close

the transaction on or about January 2, 2020. The sale of the businesses to Darling and Third Security is expected to significantly reduce the company s original 2020 cash expenditures toward

non-healthcare businesses. In addition, the Services Agreement between the company and Third Security, pursuant to which Third Security provided support services to Intrexon and its previous CEO, was not

extended and was allowed to expire on January 1, 2020.

Third Security also will purchase from the company $35M of Intrexon common stock, priced at a 5-day volume-weighted average price for the five consecutive trading days beginning on the second business day after January 14, 2020. As noted previously, the sale of the businesses to Third Security is

subject to a go-shop provision enabling the company to accept superior offers through the closing date. If Intrexon terminates the agreement with Third Security for the sale of the non-healthcare assets during the go-shop period in order to accept a higher bid, then Third Security will purchase a lower amount of Intrexon common stock equal to $88M less

the cash portion of the purchase price to be paid by the higher bidder.
