| i. | Hologic has established a management system to support its supply chain due diligence.  | 
| a. | Hologic has adopted an organizational structure and communication process that is intended to improve supply chain transparency. This system is meant to help Hologic obtain critical information regarding the supply chain of Conflict Minerals used in its products.  | 
| b. | Hologic has adopted a company policy regarding Conflict Minerals in its supply chain. This policy is publicly available at the Company’s website: http://investors.hologic.com/governance/governance-documents/default.aspx, under the heading "Product Components/Conflict Minerals". | 
| c. | Hologic has assigned authority and responsibility to a multi-disciplinary team consisting of individuals from Finance, Manufacturing, Procurement, and Information Services (collectively, the Conflict Minerals Committee). The Conflict Minerals Committee receives periodic support from Hologic’s General Counsel and reports significant Conflict Minerals matters directly to the Chief Financial Officer.  | 
| d. | Hologic has distributed communications to its suppliers making them aware of Rule 13p-1 and Hologic’s related policies and apprising them of Hologic’s expectations regarding compliance with Rule 13p-1, Hologic’s related policies and any other requests that Hologic may send to them.  | 
| e. | Hologic maintains business records relating to Conflict Minerals due diligence in accordance with the Company's existing processes. | 
| ii. | Hologic has taken steps to identify and assess risk in its supply chain.  | 
| a. | Hologic conducted a search for Conflict Minerals in its supply chain using its procurement and engineering systems. These systems contain bills-of-materials for Hologic products and an approved vendors list.  | 
| b. | Hologic engaged its immediate suppliers in an effort to identify the smelters/refiners of any Conflict Minerals in its supply chain during the Reporting Period.  | 
| c. | Hologic used the Template to assess its suppliers’ use, or lack thereof, of Conflict Minerals in the products and materials Hologic purchases.  | 
| d. | Hologic identified suppliers in its supply chain for the Reporting Period by reviewing the procurement and engineering systems and mapping the components in its bills-of-materials against the approved vendors list. Hologic sent a Template (a Survey) to the suppliers that were identified. Through May 7, 2020, a significant amount of Surveys were returned. Several follow-up reminders were sent to suppliers who did not respond to the Survey. In certain instances, if the response was too general (i.e. declaration at company level instead of product level), Hologic conducted a further assessment of the composition of the suppliers’ product or materials in an effort to determine if the product or materials contained Conflict Minerals. Hologic also reviewed Survey responses from suppliers that supplied similar products and materials to evaluate the consistency and accuracy of responses.  | 
| iii. | Hologic has designed and implemented a strategy to respond to identified risks.  | 
| a. | Hologic’s Conflict Minerals Committee monitors internal accountability with respect to the implementation of the supply chain due diligence process for Conflict Minerals compliance and reports significant findings of the supply chain risk assessment to upper level management.  | 
| b. | Hologic has designed and implemented a risk management plan that includes, but is not limited to, requests for suppliers to complete Surveys and incorporating Conflict Minerals language into Hologic’s supplier contracts. If a supplier identifies that it has Conflict Minerals in the products or materials it supplies, Hologic engages that supplier in an effort to determine the locations of the smelter(s)/refiner(s) of those Conflict Minerals.  | 
| c. | For certain Survey responses that identified smelters in Hologic's supply chain that are providing Conflict Minerals, Hologic reviewed the Responsible Minerals Initiative's (RMI) smelter list to determine if those smelters are validated as Conformant Smelters & Refiners as part of the Responsible Minerals Assurance Process (RMAP). | 
| iv. | Hologic has determined that reliance upon independent third-party audits of smelter/refiner due diligence practices by RMI is appropriate. | 
| a. | Hologic is a downstream company and is many steps removed from the smelters and refiners that produce the necessary Conflict Minerals contained in Hologic's products or components of Hologic's products. Hologic does not purchase raw minerals or ores, and does not, to the best of its knowledge, directly purchase Conflict Minerals from any of the Covered Countries. Accordingly, Hologic does not perform or direct audits of these entities' supply chains of Conflict Minerals. However, Hologic supports industry-wide efforts and the development and implementation of independent third-party audits of smelters and refiners, such as the RMI's RMAP. | 
| v. | Hologic complies with Step 5 of the OECD Guidance through the filing of this report (and the related Form SD) with the SEC and by making these materials publicly available on its website at www.hologic.com. |
