Exhibit 1.01
Mercury Systems, Inc.
Conflict Minerals Report
For the Year Ended December 31, 2022

This conflict minerals report for the year ended December 31, 2022 is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934, as amended. The U.S. Securities and Exchange Commission (“SEC”) issued Rule 13p-1 to implement the reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act. This report has been prepared based on Rule 13p-1 as further clarified by the SEC guidance issued on April 7, 2017 in its Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule. References in this report to “DRC” are to the Democratic Republic of the Congo and its adjoining countries (Tanzania, Zambia, Republic of Congo, Central African Republic, Angola, Uganda, Rwanda, South Sudan and Burundi). References in this report to “conflict minerals” are to cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which based on regulations from the SEC are limited to tin, tantalum, tungsten, and gold (“3TG”).
Our Products
Mercury Systems, Inc. (collectively with its subsidiaries, “we,” “us,” or “our”) is a technology company that delivers commercial innovation to rapidly transform the global aerospace and defense industry. Headquartered in Andover, Massachusetts, our end-to-end processing platform enables a broad range of aerospace and defense programs, optimized for mission success in some of the most challenging and demanding environments. Our Processing Platform includes signal solutions, display, software applications, networking, storage and secure processing. Our innovative solutions are mission-ready, trusted and secure, software-defined and open and modular (our differentiators), to meet customers’ most-pressing high-tech needs, including those specific to the aerospace and defense community.
During calendar year 2022, we manufactured and sold products as well as provided software and services. Manufacturing operations include manufacturing at our own facilities and by contract manufacturers using our design specifications. We provide products in the fields of radio frequency, analog-to-digital and digital to analog conversion, advanced multi- and many-core sensor processing systems, embedded security, digital storage, and digital radio frequency memory solutions, software defined communications capabilities, and advanced security technologies and capabilities. Examples of our products include: power amplifiers and limiters; switches; oscillators; filters; equalizers; digital and analog converters; chips; MMICs (monolithic microwave integrated circuits); memory and storage devices; embedded processing modules; embedded processing boards; switch fabric boards; high speed input/output boards; digital receiver boards; graphics and video processing and Ethernet and IO (input-output) boards; multi-chip modules; integrated radio frequency and microwave multi-function assemblies; tuners; transceivers; rack-mount servers; display head assemblies; and integrated subsystems that include multiple modules and/or subassemblies. Conflict minerals, as defined by the regulations of the SEC (i.e., tin, tantalum, tungsten, and gold, or 3TG), are essential to the functionality of most electronic devices and their use is extensive in the electronics industry. Examples of the use of conflict minerals in electronics include: tin solder for joining circuits; tantalum in capacitors; tungsten in metal wires, electrodes, and electrical contacts; and gold in electric plating and circuit boards.
We performed a review of our products considering the SEC’s conflict minerals regulations and the vendors supplying the components and materials incorporated into our products. Components and connectors incorporated into our products could contain conflict minerals as defined by the SEC, regardless of the country of origin of those minerals.

Our Calendar Year 2022 Reasonable Country of Origin Inquiry and Supply Chain Due Diligence
We do not engage in the extraction, transportation, handling, trading, processing, smelting, refining, or alloying of any conflict minerals and we do not acquire conflict minerals directly from any smelter or refiner, regardless of country of origin. To the extent that conflict minerals may be incorporated into our products, they are acquired through our supply chain in the form of components, connectors, solder, and other materials that we or our contract manufacturers incorporate into our finished products. We designed our conflict minerals reasonable country of origin inquiry and supply chain due diligence around our product manufacturing supply chain. We defined the scope of our conflict minerals inquiry by identifying and contacting the suppliers on our approved vendor list that provide components or other materials that may contain conflict minerals. We rely upon our suppliers to provide information on the origin of the conflict minerals contained in materials supplied to us, including sources of conflict minerals that are supplied to them from sub-tier suppliers. We expect our suppliers to provide us with sourcing information per our conflict minerals policy.
In general, we encountered the following challenges in obtaining responses from our suppliers:
we are dependent on information received from our direct suppliers to conduct our reasonable country of origin inquiry process; and
we have a varied supplier base with differing levels of resources and sophistication, and many of our suppliers are not themselves subject to Rule 13p-1 of the Securities Exchange Act of 1934, as amended.

Our Approved Vendor List
Our supply chain approved vendor list (“AVL”) contained 1,461 tier 1 suppliers identified as in-scope for conflict mineral regulatory purposes and which were contacted as part of our reasonable country of origin inquiry. In many cases, for a given component in one of our products, we have multiple vendors as a source for that component and each of those vendors is listed on our AVL. Our procedures for adding a vendor to our AVL include a review of the vendor’s conflict minerals status as part of the approval process.
Our Conflict Minerals Policy Statement and Supplier Outreach
Our conflict minerals policy statement is posted on our corporate website,, under the heading “Company,” then “Environmental, Social and Governance,” and then “Responsible Sourcing.” Our conflict minerals due diligence process included the development of a conflict minerals policy, establishment of a cross-functional team, engagement of a third-party vendor to conduct supply chain due diligence, communication with suppliers, gathering compliance data, and measuring and internally reporting our due diligence progress. We distributed supplier notices summarizing our conflict minerals policy to the suppliers on our AVL. For our calendar year 2022 Reasonable Country of Origin Inquiry (“RCOI”), we engaged Source Intelligence to enhance our conflict minerals compliance program.
The suppliers on our AVL were included in the RCOI performed by Source Intelligence. Prior to being asked to provide conflict minerals data, suppliers were asked a series of questions to determine whether the products they supply to us contain 3TG which is necessary to the functionality or production of our products. This information was used to determine which suppliers were in scope for regulatory purposes and thus asked to provide additional conflict minerals information.
We engaged with Source Intelligence to develop a list of suppliers determined to be in-scope for regulatory purposes based on our influence over the manufacturing process (i.e., meeting the manufacture

or contract to manufacture definitions in SEC Rule 13p-1) and potential use of 3TG. Source Intelligence contacted our suppliers to collect information about the presence and sourcing of the 3TG used in the products and components supplied to us. This program utilized the Conflict-Free Sourcing Initiative’s Conflict Minerals Reporting Template (“CMRT”). Suppliers were offered two options to submit the required information, either by uploading the CMRT in Excel format or by completing an online survey version of this template directly in the Source Intelligence platform.
Source Intelligence sent an email to suppliers containing a registration and survey request link for the on-line data collection platform. Following the initial introductions to the program and information request, one email reminder was sent to each non-responsive supplier requesting survey completion. In recognition that the information requested can take time to collect and aggregate, suppliers were given a final deadline of March 31, 2023 to provide information about the metal processors present in their supply chains for the calendar 2022 reporting year. Suppliers were asked to provide information regarding the sourcing of their materials with the goal of identifying the 3TG smelters or refiners and associated mine countries of origin. Suppliers who had already performed a RCOI using the CMRT were asked to upload this document into the Source Intelligence system or to provide this information in the online survey version. We chose to give our suppliers the ability to share information at a level with which they were most comfortable, i.e. company, product or user-defined, but the declaration scope had to be specified. Suppliers were requested to provide an electronic signature before submitting their data to verify that all answers submitted were accurate to the best of the supplier’s knowledge, but the suppliers were not required to provide an electronic signature to submit their data. Source Intelligence evaluated the supplier responses for plausibility, consistency, and gaps. If any of the following quality control flags were raised, suppliers were automatically contacted by Source Intelligence on a bi-weekly basis up to three times:
one or more smelters or refiners were listed for an unused metal;

smelter or refiner information was not provided for a used metal, or such information provided was not a verified metal processor;

the supplier answered yes to sourcing from the Democratic Republic of the Congo or adjoining countries, but none of the smelters or refiners listed are known to source from the region;

the supplier indicated that they have not received conflict minerals data for each metal from all relevant suppliers;

the supplier indicated they have not identified all of the smelters or refiners used for the products included in the declaration scope;

the supplier indicated they have not provided all applicable smelter or refiner information received; and

the supplier indicated 100% of the 3TG for products covered by the declaration originates from scrap/recycled sources, but one or more smelters or refiners listed are not known to be exclusive recyclers.

For supply chains with smelters or refiners that are known or thought to be sourcing from the Democratic Republic of the Congo or adjoining countries, additional investigation was conducted to determine the source and chain-of-custody of the regulated metals. Source Intelligence relies on the following internationally accepted audit standards to determine which smelters or refiners are considered “DRC Conflict Free”: the Responsible Minerals Assurance Process (“RMAP”); the London Bullion Market Association Good Delivery Program (“LBMA”); and the Responsible Jewellery Council Chain-of-Custody Certification (“RJC”). Source Intelligence is an official vendor member of the Responsible

Minerals Initiative (“RMI”) to further facilitate the exchange of supply chain data and technical information in the quest for global ethical sourcing of materials.
If the smelter or refiner is not certified by these internationally recognized standards, Source Intelligence attempts to contact them to gain more information about their sourcing practices, including countries of origin and transfer, and whether there are any internal due diligence procedures in place or other processes they undertake to track the chain-of-custody on the source of their mineral ores. Relevant information reviewed includes: whether the smelter or refiner has a documented, effective, and communicated conflict-free policy; an accounting system to support a mass balance of materials processed; and traceability documentation. Source Intelligence also performs internet research to determine whether there are any outside sources of information regarding the smelter or refiners sourcing practices. Source Intelligence attempts up to three contacts to smelters or refiners to gather information on mine country of origin and sourcing practices.
Appendix A to this report contains each unique smelter-metal combination reported to be in our supply chain with additional information from the Source Intelligence smelter database, including metal, smelter name, smelter country, and conflict-free certifications.
