March 3, 2022

Breda, the Netherlands – argenx (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today reported financial results for the full year 2021 and provided a fourth quarter business update.

“2021 was a transformational year for argenx, culminating with the FDA approval of VYVGART, our first-in-class FcRn blocker, in December. We carried this momentum into 2022 with the official U.S. launch of VYVGART and the Japan approval. We were well-prepared to launch VYVGART at the time of approval and are encouraged by the early response of the medical community, the engagement from patients, and the coverage decisions that have been made by payers. We continue to expect steady launch progress in 2022 as we aim to deliver this new therapy to patients living with generalized myasthenia gravis,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx.

“In addition to executing the global commercial launch of VYVGART, we are primed to deliver several upcoming catalysts through our development pipeline in high-value autoimmune indications. We expect multiple registrational trial readouts for efgartigimod in the next four quarters, the first of which is the SC bridging study in gMG this month. We are expanding the scope of development for efgartigimod to 10 indications and ARGX-117 to two indications by the end of this year, and will also advance ARGX-119 into first-in-human studies. We remain focused on all components of our integrated business so that we can continue to redefine immunology on behalf of patients and deliver shareholder value,” continued Mr. Van Hauwermeiren.

FOURTH QUARTER AND FULL YEAR 2021 FINANCIAL RESULTS

DETAILS OF THE FINANCIAL RESULTS

Cash, cash equivalents and current financial assets totaled $2,336.7 million as of December 31, 2021, compared to $1,996.5 million on December 31, 2020. The increase in cash and cash equivalents and current financial assets resulted primarily from the closing of a global offering of shares, which resulted in the receipt of $1,092.1 million in net proceeds in February 2021 and the net receipt of a $73.1 million non-creditable, non-refundable development cost-sharing payment from Zai Lab as part of the strategic collaboration for efgartigimod in Greater China in part offset by the payment of $98.0 million related to the purchase of the priority review voucher from Bayer HealthCare Pharmaceuticals, and other net cash flows used in operating activities.  

Revenue increased by $456.0 million for the twelve months ended December 31, 2021 to $497.3 million, compared to $41.2 million for the twelve months ended December 31, 2020. The increase was primarily due to the recognition of the transaction price as a consequence of the termination of the collaboration agreement with Janssen resulting in the one-time 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 cost-sharing payment and the development milestone, triggered by the FDA approval of VYVGART.

Other operating income increased by $18.5 million to $42.1 million for the year ended December 31, 2021, compared to $23.7 million for the year ended December 31, 2020. The increase was primarily driven by (i) the increase in research and development incentives, as a result of the increased research and development costs incurred, (ii) the increase in payroll tax rebates, as a direct result of the increase in the employment of highly qualified research and development personnel eligible for specific payroll tax rebates, and (iii) the increase in fair value of argenx’s profit share in AgomAb Therapeutics NV.
  
Research and development expenses increased by $209.6 million for the twelve months ended December 31, 2021 to $580.5 million, compared to $370.9 million for the twelve months ended December 31, 2020. The increase resulted primarily from higher external research and development expenses, mainly related to the efgartigimod program in various indications and other clinical and preclinical programs. Furthermore, the research and development personnel expenses increased due to a planned increase in headcount and the increased costs of the share-based payment compensation plans related to the grant of stock options.  

Selling, general and administrative expenses totaled $307.6 million for the twelve months ended December 31, 2021, compared to $171.6 million for the twelve months ended December 31, 2020. The increase resulted primarily from higher personnel expenses, including the costs of the share-based payment compensation plans related to the grant of stock options, and consulting fees linked to the preparation for a commercialization of VYVGART.  

Exchange losses totaled $50.1 million for the twelve months ended December 31, 2021, compared to $126.2 million for the twelve months ended December 31, 2020 and are mainly attributable to unrealized exchange rate losses on the cash, cash equivalents and current financial assets position in Euro.

FINANCIAL GUIDANCE
Based on current plans to fund anticipated operating expenses and capital expenditures, argenx expects to utilize up to half of its available cash, cash equivalents and current financial assets in 2022. The increased spend will support the global VYVGART launches, clinical development of efgartigimod in 10 indications and ARGX-117 in two indications, investment in the global supply chain, and continued focus on pipeline expansion through the Immunology Innovation Program.
