PRECIGEN COMPLETES SERIES OF TRANSACTIONS TO SOLIDIFY HEALTHCARE FOCUS

- Company on Track to Advance Next-Generation Gene & Cell Therapies -

- Company Name Changes to Precigen from Intrexon and Ticker Symbol to Nasdaq: PGEN -

GERMANTOWN, Md., Feb. 3, 2020 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 the closing of its previously announced sale of a number of its bioengineering assets and the related sale of $35 million of its common

stock to an affiliate of Third Security LLC. Additionally, effective February 1, 2020, the Company has changed its name to Precigen, Inc. from Intrexon Corporation and its Nasdaq stock symbol to PGEN from XON. The new Precigen enters 2020 with

a promising portfolio of investigational gene and cell therapies, derived from the Company s transformative therapeutic platforms, including UltraCAR-T , AdenoVerse cytokine therapies, multifunctional therapeutics and off-the-shelf AdenoVerse immunotherapies, as well as innovative approaches from our subsidiaries ActoBio Therapeutics, Exemplar Genetics, and Triple-Gene.

With multiple data read-outs on track for our internal pipeline and partnered programs, we believe 2020 will be an exciting year for Precigen,

said Helen Sabzevari, Ph.D., President and CEO of Precigen. At the same time, we plan to further optimize our portfolio this year through a renewed commitment to financial rigor and fiscal discipline.

We are particularly enthusiastic about the opportunity to advance our UltraCAR-T platform as current CAR-T

treatments rely on a long, complex, and relatively inefficient manufacturing process that delays treatment for cancer patients and leads to high pricing. By contrast, UltraCAR-T is designed to overcome many of these obstacles by eliminating the need

for ex vivo expansion, reducing overall manufacturing time, and enabling patients to be treated with CAR-T therapy only one day after non-viral gene

transfer at the cancer center. UltraCAR-T has the potential to democratize patient care by simplifying this life-saving cancer immunotherapy which should improve availability throughout the world, added

Two non-healthcare businesses remain with Precigen and the Company will continue to evaluate

strategic and operational options for these businesses.

Dr. Sabzevari presented an overview of Precigen at the 38th Annual J.P. Morgan Healthcare Conference on January 14, 2020, and a replay of the presentation is available on Precigen s website in the Events section at
