Section 1 – Conflict Minerals Disclosure

Block, Inc. (the “Company”) is filing this Form SD pursuant to Rule 13p-1 promulgated under the Securities Exchange Act of 1934, as amended, for the reporting period January 1, 2024 to December 31, 2024.

The Company’s primary hardware products include its magstripe reader, contactless and chip reader, Square Stand, Square Register, Square Terminal, and Bitkey (the “Covered Products”), each of which are manufactured by third parties. For additional information related to the Covered Products, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the Securities and Exchange Commission.

Reasonable Country of Origin Inquiry

Following the Company’s initial determination that its hardware products contain components with metallic forms of tin, tungsten, tantalum and/or gold (“3TG”) minerals (derived from columbite-tantalite (coltan), cassiterite, gold, or wolframite, “Conflict Minerals”), the Company conducted a Reasonable Country of Origin Inquiry (“RCOI”) to determine whether such 3TG minerals may have originated in the Democratic Republic of the Congo and/or any of its adjoining countries (the “Covered Countries”). To assess the Company’s position within the supply chain, the Company requested its direct suppliers to provide responses to the Conflict Minerals Reporting Template (“CMRT”), a standardized reporting template developed by the Responsible Minerals Initiative.

The Company received responses to the CMRT from suppliers that represented all of the Company’s contract manufacturers during the applicable period. The Company reviewed responses received to the CMRT for completeness and consistency, and followed up with suppliers for any corrections and clarifications as needed. The suppliers’ CMRT responses identified lists of smelters or refiners, and their countries of origin, that may have supplied 3TG minerals utilized in the Covered Products during the applicable period. According to the CMRT responses, some of the 3TG minerals used in the Company’s Covered Products may have originated in the Covered Countries and might not have been exclusively sourced from scrap or recycled sources.

The Company believes its RCOI process was reasonably designed and performed in good faith; however, there are inherent limitations in the information provided by third parties, including the possibility of information being inaccurate, incomplete or falsified despite the Company’s efforts to validate and confirm the information. Furthermore, the Company relied on industry association sponsored smelter/refiner audits which may have limitations or errors/omissions in the provided audits.

Determination from RCOI

Based on the results of RCOI, the Company determined that, with respect to necessary 3TG in its Covered Products, the 3TG minerals may have originated from the Covered Countries, and therefore exercised due diligence on the source and chain of custody of the necessary 3TG.
