### Company Overview
Mercury is a technology company that delivers mission-critical processing power to the edge — where signals and data are collected — to solve the most pressing aerospace and defense challenges. Mercury's products and solutions are deployed in more than 300 programs and across 35 countries. The Mercury Processing Platform is the unique advantage we provide to our customers. It comprises the innovative technologies we've developed and acquired for more than 40 years that bring integrated, mission-critical processing to the edge. Our processing platform spans the full breadth of signal processing — from radio frequency front end to the human-machine interface — to rapidly convert meaningful data, gathered in the most remote and hostile environments, into critical decisions. It allows us to offer standard products and custom solutions from silicon to system scale, including components, modules, subsystems, and systems, and it embodies the customer-centric approach we take to delivering capabilities that are mission-ready, trusted and secure, software-defined, and open and modular.
