**argenx Announces Planned Transition of Chief Operating Officer**

· Karen Massey appointed as Chief Operating Officer, effective March 13, 2023

· Keith Woods to retire and serve as Advisor on argenx Board of Directors

**March 2, 2023**

**Amsterdam, the Netherlands —** argenx (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced that Karen Massey will join argenx as Chief Operating Officer, effective March 13, 2023. Ms. Massey will succeed Keith Woods, who will remain at argenx for a transition period to support the launch of subcutaneous efgartigimod, after which he will retire and serve as a strategic advisor on the Commercial Committee of the argenx Board of Directors.

"Karen brings extensive commercial launch and leadership experience to argenx, specifically within neurology and autoimmune disease. Most recently, her leadership accelerated the post-launch performance of Ocrevus in multiple sclerosis, a dynamic market that is often compared to myasthenia gravis. Karen has a genuine passion for innovation and an ability to inspire large, diverse and global teams to deliver results by creating a sense of shared purpose and community," commented Tim Van Hauwermeiren, Chief Executive Officer at argenx. "Karen's appointment is the result of careful succession planning and a thorough process to find the right leader at this important time in our company history. I am confident that she will make a significant impact at argenx as we work together to bring innovative medicines to patients."

"I would like to extend a warm thank you to my friend and colleague, Keith Woods, who joined the company in 2018 with a commitment to build a global infrastructure ahead of our first commercial launch. He accomplished this and so much more – leading us through a very successful first launch-year while always inspiring our colleagues to keep the patient at the center of everything we do. I wish him well in his much-deserved next phase of life and look forward to his ongoing contributions as an advisor on our Board," continued Mr. Van Hauwermeiren.

Ms. Massey has over 20 years' experience in the pharmaceutical and biotechnology industry with an impressive breadth of experience across commercial, product development, corporate strategy & innovation. She joins argenx from Genentech (Roche Group), where she most recently served as Senior Vice President of Product Development and Global Clinical Operations. In this capacity, she led a global organization of more than 2,000 people across 24 countries and was accountable for operationalizing over 300 clinical trials within oncology, neuroscience, infectious diseases, immunology and ophthalmology. During her 9-year tenure at Genentech, Ms. Massey held various commercial leadership roles across marketing and business operations, including as the Vice President of the Multiple Sclerosis and Neuromyelitis Optica business, leading the team to accelerate the post-launch performance of Ocrevus. Ms. Massey started her biopharmaceutical career in marketing at Pfizer and returned there, after two years as a management consultant at Bain, to take on leadership positions in corporate strategy, sales and as a commercial lead in Latin America. Ms. Massey holds a Bachelor of Economics from the University of Sydney and a Master of Business Administration from the New York University Stern School of Business.

"argenx has demonstrated incredible growth transitioning from a research and development organization to an integrated, immunology company. This success has been built on a commitment to creating patient value through innovation. I am very excited by the opportunity to continue to build on that foundation as we look to realize the full potential of VYVGART and the pipeline candidates within our commercial franchises," commented Ms. Massey.

"Looking ahead, we have the opportunity this year to showcase the innovation within our pipeline through multiple data catalysts, including three pivotal data readouts from efgartigimod and the first clinical efficacy data from ARGX-117, our next pipeline-in-a-product candidate. We are well-equipped to build on this significant momentum as we advance our mission to redefine the treatment of autoimmune disease."

**DETAILS OF THE FINANCIAL RESULTS** 

**Total operating income** for the fourth quarter and year-to-date in 2022 was $182.1 million and $445.3 million, respectively, compared to $33.7 million and $539.4 million for the same periods in 2021, and consists of:

&nbsp;&nbsp;&nbsp;&nbsp;· **Product net sales** from the sales of VYVGART
for the three months ended December 31, 2022 were $173.4 million. The product net sales in the twelve months ended December 31, 2022 were
$400.7 million. No product net sales were recognized during the same period in 2021.

&nbsp;&nbsp;&nbsp;&nbsp;· **Collaboration revenue** for the fourth quarter and year-to-date in 2022 was $0.8 million and $10 million, respectively, compared
to $26 million and $497.3 million for the same periods in 2021. The collaboration revenue during the twelve months ended December 31,
2022 primarily relates to the recognition of milestone revenue following the option exercise by LEO Pharma to enter into a commercial
license for ARGX-112. The collaboration revenue for the twelve months ended December 31, 2021 was primarily attributable to the recognition
of the transaction price as a consequence of the termination of the collaboration agreement with Janssen, resulting in the recognition
of $315.1 million, and the recognition of $177.5 million in collaboration revenue related to the strategic collaboration with Zai Lab,
including the development milestone which was triggered by the FDA approval of VYVGART.

&nbsp;&nbsp;&nbsp;&nbsp;· **Other operating income** for the fourth
quarter and year-to-date in 2022 was $7.9 million, and $34.5 million, respectively, compared to $7.7 million and $42.1 million for the
same periods in 2021. During the twelve months ended December 31, 2022, and December 31, 2021, the fair value of the argenx profit share
in AgomAb Therapeutics NV increased by $4.3 million and $11.2 million respectively. The increase is a result of the extension of a Series
B financing round by AgomAb for which argenx maintains a profit share in exchange for granting the license for the use of HGF-mimetic
antibodies from the SIMPLE Antibody™ platform.

**Total operating expenses** for the fourth quarter and year-to-date in 2022 were $296.5 million and $1,165.6 million, respectively, compared to $264.6 million and $888.2 million for the same periods in 2021, and consists of:

&nbsp;&nbsp;&nbsp;&nbsp;· **Cost of sales** for the fourth quarter and
year-to-date in 2022 was $12.8 million and $29.4 million, respectively. The cost of sales was recognized with respect to the sale of VYVGART
during 2022. There was no cost of sales recognized in the comparable prior year periods.

&nbsp;&nbsp;&nbsp;&nbsp;· **Research and development expenses** for
the fourth quarter and year-to-date in 2022 were $147.8 million and $663.4 million, respectively, compared to $167.2 million and $580.5
million for the same periods in 2021. The research and development expenses mainly relate to external research and development expenses
and personnel expenses incurred in the clinical development of efgartigimod in various indications and the expansion of other clinical
and preclinical pipeline candidates. The increase in research and development expense during 2022 is mainly driven by the recognition
of the priority review voucher submitted with the BLA filing for SC efgartigimod for the treatment of gMG, which resulted in an expense
of $99.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;· **Selling, general and administrative expenses** for the fourth quarter and year-to-date in 2022 were $135.3 million and $472.1 million, respectively, compared to $97.4 million and $307.6
million for the same periods in 2021. The selling, general and administrative expenses mainly relate to professional and marketing fees
linked to the commercialization of VYVGART in the U.S., Japan and the EU and personnel expenses.

![](tm238287_ex99-2img001.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;· **Loss from investment in joint venture** for
the fourth quarter and year-to-date in 2022 was $0.7 million. The loss recognized was argenx's share of losses in Oncoverity, Inc.
There was no losses from investment in joint venture in the comparable prior year periods.

**Financial income** for the fourth quarter and year-to-date in 2022 were $13.9 million and $27.7 million respectively, compared to $1.2 million and $3.6 million for the same periods in 2021. The increase in financial income is mainly due to an increase in interest income on current financial assets and cash and cash equivalents attributable to higher interest rates.

**Exchange gains/losses** for the fourth quarter and year-to-date in 2022 were $60.3 million of gains and $32.7 million of losses, respectively, compared to $14.1 million and $50.1 million of exchange losses for the same periods in 2021. Exchange gains/losses are mainly attributable to unrealized exchange rate losses on the cash, cash equivalents and current financial assets position in Euro.

**Income tax** for the fourth quarter and year-to-date in 2022 was $2.6 million and $19.7 million of tax benefit, respectively, compared to $7.1 million of tax benefit and $8.5 million of tax expense for the same periods in 2021. Tax benefit for the three months ended December 31, 2022 consists of $12.1 million of income tax expense and $14.7 million of deferred tax income, compared to $1.2 million of income tax expense and $8.2 million of deferred tax income for the same period in 2021.

**Net loss** for the fourth quarter and year-to-date in 2022 was $38.6 million and $709.6 million, respectively, compared to net loss of $237.8 and $408.3 million for the same periods in 2021.

**Cash, cash equivalents and current financial assets** totaled $2.2 billion as of December 31, 2022, compared to $2.3 billion as of December 31, 2021. Net change in Cash and cash equivalents and current financial assets is primarily a result of the closing of a global offering of shares, which resulted in the receipt of $761.0 million in net proceeds in March 2022, offset by net cash flows used in operating activities.

**FINANCIAL GUIDANCE**

Based on current plans to fund anticipated operating expenses, working capital and capital expenditures, argenx expects to utilize up to $500 million cash in 2023.
