Section 1    Conflict Minerals Disclosure

Item 1.01     Conflict Minerals Disclosure and Report

This Specialized Disclosure Report on Form SD (“Form SD”) of McKesson Corporation (“Company”) is filed pursuant to Rule 13p-1 (“Rule”) promulgated under the Securities Exchange Act of 1934 for the reporting period January 1, 2023 to December 31, 2023 (“Reporting Period"). The Rule requires disclosure of certain information when a company manufactures or contracts to manufacture products for which the minerals specified in the Rule are necessary to the functionality or production of those products. The minerals specified in the rule are gold, columbite-tantalite (coltan), cassiterite and wolframite, including their derivatives, which are limited to tantalum, tin and tungsten (collectively, “Conflict Minerals”). As provided by applicable guidance from the U.S. Securities and Exchange Commission (“SEC”) regarding the Rule, this disclosure does not address products that did not enter the stream of commerce during the Reporting Period.

The following disclosure, in response to the provisions of paragraphs (a) and (b) of Item 1.01 of Form SD, has been made 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 SEC on April 7, 2017 (“April 2017 Guidance”). As permitted under the April 2017 Guidance, this Form SD does not address Item 1.01(c) of Form SD.

Conflict Minerals Disclosure

Description of the Company’s Products

This Form SD relates to products (i) for which Conflict Minerals are necessary to the functionality or production of that product; (ii) that were manufactured, or contracted to be manufactured, by the Company; and (iii) for which the manufacture was completed during the Reporting Period. These products (collectively, “Covered Products”) consist of the Company’s pharmacy automation products.

Reasonable Country of Origin Inquiry

The Company has, in good faith and after reasonable due diligence, conducted a reasonable country of origin inquiry (“RCOI”) to determine whether Conflict Minerals that are necessary to the functionality or production of its Covered Products originated in the Democratic Republic of the Congo (“DRC”) or the adjoining countries of Angola, Burundi, Central African Republic, Republic of Congo, Rwanda, South Sudan, Tanzania, Uganda and Zambia (“Covered Countries”), or whether any of the Conflict Minerals may have been from recycled or scrap sources. A summary of the Company’s RCOI process follows:

The Company’s supply chain with respect to the Covered Products is complex, and there are many third parties in the supply chain between the ultimate manufacturer of the Covered Products and the original sources of the Conflict Minerals. The Company does not purchase Conflict Minerals directly from mines, smelters or refiners. The Company must therefore rely on its suppliers to provide information regarding the origin of the Conflict Minerals that are necessary to the functionality or production of the Covered Products.

As an initial step, each of McKesson’s business units that manufacture or contract to manufacture Covered Products were asked to evaluate the Covered Products to determine if Conflict Minerals may have been present and potentially necessary to the production or functionality of the Covered Product. Following that evaluation, each business unit used a risk-based approach to create a list of suppliers that were likely to have provided products containing Conflict Minerals during the Reporting Period.

The Company's RCOI included an inquiry of its pharmacy automation suppliers. The responses to the Company’s inquiry can be grouped into the three categories identified below:

(1)The supplier represented that its products do not contain Conflict Minerals from the Covered Countries.

(2)The supplier represented that its products contain Conflict Minerals that were sourced only from smelters or refiners that used Conflict Minerals only from recycled or scrap sources as defined in Item 1.01(d)(6) of Form SD.

(3)The supplier represented that its products contain Conflict Minerals for which the supplier either is unable to confirm whether the source of the Conflict Minerals was in the Covered Countries or is unable to confirm that the smelters or refiners (if any) from which the Conflict Materials were sourced used only recycled or scrap sources as defined in Item 1.01(d)(6) of Form SD.

Based on this RCOI, the Company has reason to believe that certain of its necessary Conflict Minerals contained in some Covered Products may have originated in a Covered Country and are not from recycled or scrap sources.
