Leiden, The Netherlands,29 March 2019:Pharming Group N.V. ("Pharming" or "the Company")

(Euronext Amsterdam: PHARM) announces publication of its Annual Report for the financial year ended 31 December 2018. The Company also announces that it has made a provisional commitment to invest up to €1.6 million in cash and convert €2.5 million of prepayments into equity in its fill & finish partner BioConnection BV, which manufactures the final sealed vials of Pharming's product RUCONEST® from the purified drug substance.

BioConnection BV is a fast-growing profitable private company with a global customer base. To match a growing demand of GMP fill & finish services in the biopharmaceutical market, BioConnection is seeking to expand its manufacturing and production capacity. As one of its largest customers and one which will benefit strongly from the increased capacity in due course, Pharming has agreed to take a minority stake in the company.

Other current shareholders of BioConnection are also supporting the company with additional investments. The investment, which is still subject to agreement on final documentation, is expected to close next week.

Chief Executive Officer Sijmen de Vries said:

"BioConnection has been an excellent partner for Pharming for many years, and is an important part of our future plans. While we do not intend to take an active operational role in the company, its successful expansion will directly benefit Pharming as we look to increase capacity to support growing demand for RUCONEST® and as we expand our pipeline."

Angioedema ("HAE") attacks in patients in Europe, the US, Israel and South Korea. The product is available on a named-patient basis in other territories where it has not yet obtained marketing authorization.

RUCONEST® has recently completed a clinical trial for the treatment of HAE in young children (2-13 years of age) and is also evaluated for various additional follow-on indications.

Pharming's technology platform includes a unique, GMP-compliant, validated process for the production of pure recombinant human proteins that has proven capable of producing industrial quantities of high quality recombinant human proteins in a more economical and less immunogenetic way compared with current cell-line based methods. Leads for enzyme replacement therapy ("ERT") for Pompe and Fabry's diseases are being optimized at present, with additional programs not involving ERT also being explored at an early stage at present.

Pharming has a long-term partnership with the China State Institute of Pharmaceutical Industry ("CSIPI"), a Sinopharm company, for joint global development of new products, starting with recombinant human Factor VIII for the treatment of Haemophilia A. Pre-clinical development and manufacturing will take place to global standards at CSIPI and are funded by CSIPI. Clinical development will be shared between the partners with each partner taking the costs for their territories under the partnership.
