Penumbra (PEN) SDConflict minerals disclosure

This Specialized Disclosure Report on Form SD (this “Form SD”) of Penumbra, Inc. (“Penumbra,” the “Company,” “we,” or “us”) for the year ended December 31, 2022 is being filed to comply with Rule 13p-1 under the Securities Exchange Act of 1934, as amended (the “Rule”).

Penumbra, headquartered in Alameda, California, is a global healthcare company focused on innovative therapies. Penumbra designs, develops, manufactures and markets novel products and has a broad portfolio that addresses challenging medical conditions in markets with significant unmet need. Some of our products contain small amounts of tin, tungsten, and/or gold that are necessary to the functionality or production of those products. Substantially all of our products are manufactured at our manufacturing facilities in Alameda and Roseville, California. Penumbra does not purchase ore or unrefined tin, tungsten or gold from mines and instead relies on a small number of suppliers that provide us with materials containing these minerals. We rely on these suppliers to assist us with our reasonable country of origin inquiry regarding the minerals contained in the materials that they supply to us.

Penumbra has evaluated its products that were manufactured during the calendar year ended December 31, 2022 (the “Reporting Period”), and has determined that certain of such products contain “conflict minerals,” which, for purposes of this Form SD, means columbite-tantalite, also known as coltan (the metal ore from which tantalum is extracted); cassiterite (the metal ore from which tin is extracted); gold; wolframite (the metal ore from which tungsten is extracted); and their derivatives (collectively, “3TG Minerals”). Specifically, certain of Penumbra’s thrombectomy, embolization, immersive healthcare and access products contain tin, tungsten, and/or gold. These 3TG Minerals are necessary for the functionality or production of these products.

The Company has identified ten suppliers (the “3TG Suppliers”) that supplied materials containing 3TG Minerals that were used in Penumbra products whose manufacture was completed during the Reporting Period (the “Products”).

The Company conducted a reasonable country of origin inquiry (“RCOI”) on the 3TG Suppliers to determine whether the 3TG Minerals used in the Products originated in the Democratic Republic of the Congo or an adjoining country (collectively, the “Covered Countries”). The RCOI involved the following steps:

Of the ten 3TG Suppliers, four confirmed via their CMRT and related documentation that the 3TG minerals contained in their materials supplied to the Company and contained in the Products were obtained from smelters that do not source 3TG Minerals from the Covered Countries. These 3TG Suppliers also confirmed via their CMRT that they had received responses to their supply chain survey from one hundred percent (100%) of the relevant smelters.

One 3TG Supplier, which supplies materials containing tungsten for use in the Products, informed the Company that responses to their supply chain survey indicated that the 3TG Minerals contained in their materials supplied to the Company and contained in the Products were obtained from smelters that do not source 3TG Minerals from the Covered Countries, but that the 3TG Supplier had received responses to their supply chain survey from less than one hundred percent (100%) of the relevant smelters. Penumbra requested additional information from this 3TG Supplier and reviewed publicly available information (including but not limited to the 3TG Supplier’s Conflict Minerals Policy) to confirm the 3TG Supplier’s commitment to conflict-free sourcing.

Based on responses received, the Company determined that 3TG Minerals present in certain of the Products may have originated in the Covered Countries and may not be from scrap or recycled sources. The Company has elected not to file disclosure under Item 1.01(c) of Form SD in accordance with the “Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule” issued by the Division of Corporation Finance of the Securities and Exchange Commission (the “SEC”) on April 7, 2017.
