Company

Company overview

Grifois collects plasma, mainly through its own donation centers, then separates and purifies the proteins into medicines. These treatments serve patients with immune deficiencies and other serious conditions. Plasma-derived medicines generate the vast majority of revenue; immunoglobulins, including Gamunex-C and Xembify, account for most company sales.

Hospitals, specialty pharmacies and distributors buy its products. In the United States, group purchasing organizations negotiate prices and supply volumes for member hospitals, and Grifois sells to authorized distributors that resell to those members. In Europe, most medicine sales go directly to hospitals. The United States is its main market, and pricing and insurance reimbursement affect access to its treatments.

The business depends on healthy donors supplying enough plasma, particularly in the United States, and on how much usable protein Grifois can extract from it. Products sold in the United States must use plasma collected at FDA-approved centers. Collection centers and manufacturing plants must maintain regulatory approval and comply with manufacturing-quality standards to keep operating.

Grifols’ results hinge on immunoglobulin demand and plasma collection costs, with CSL Behring, absent from this list, a key rival across its core plasma therapies.

  • Takeda competes with Grifols to sell plasma-derived medicines for immunoglobulin and alpha-1 antitrypsin treatment, and both depend on plasma availability and collection costs. Watch Takeda’s immunoglobulin pricing: Grifols says competitors’ discounts can force it to lower prices or lose sales.

  • ADMA Biologics, Inc. both competes with Grifols in intravenous immunoglobulins for patients with primary immunodeficiency and pays Grifols for plasma rich in RSV antibodies to make ASCENIV. Watch its ASCENIV plasma purchases: the agreement requires Grifols to supply at least 35,000 liters annually through September 2039.

  • Kamada Ltd competes with Grifols in specialty plasma medicines, including treatments that replace deficient alpha-1 antitrypsin, selling directly and through partners and distributors. Its GLASSIA sales offer a focused view of the treatment market in which Grifols is one of Kamada’s two main rivals.

  • argenx sells VYVGART treatments that compete with Grifols’ immunoglobulins for patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and other overlapping conditions. Watch VYVGART’s CIDP sales and reimbursement agreements: CIDP is one of the patient groups supporting Grifols’ immunoglobulin growth.

  • QuidelOrtho Corporation competes with Grifols to sell transfusion tests to blood banks, but also buys the test ingredients known as antigens from Grifols under a multi-year agreement making Grifols its exclusive supplier. Watch QuidelOrtho’s donor-screening business for a read on demand for these ingredients, which Grifols continues supplying after their joint business arrangement ended effective January 1, 2026.
