Business Description

Overview At Plexus, we help create the products that build a better world. Driven by a passion for excellence, we partner with our customers to design, manufacture and service highly complex products in demanding regulatory environments. From life-saving medical devices and mission-critical aerospace and defense products to industrial automation systems and semiconductor capital equipment, our innovative solutions across the lifecycle of a product converge where advanced technology and human impact intersect. We provide these solutions to market-leading as well as disruptive companies globally in the Aerospace/Defense, Healthcare/Life Sciences, and Industrial market sectors, supported by a global team of over 20,000 members across our 26 facilities in the Americas ("AMER"), Asia-Pacific ("APAC") and Europe, Middle East and Africa ("EMEA") regions. Our Vision, Mission and Strategy Our vision is to help create the products that build a better world. Our mission is to be the leader in highly complex products and demanding regulatory environments. Our strategy to fulfill our vision and mission consists of four strategic pillars: • Market Focus – We engineer innovative solutions for customers in growth markets featuring highly complex products and demanding regulatory environments. • Superior Execution – We are dedicated partners to our customers, committed to achieving zero defects and perfect delivery through operational excellence. • Passion Meets Purpose – We are united as a team and guided by our values. We do the right thing to support our team members, customers and communities. • Discipline by Design – We hold ourselves accountable to delivering shareholder value through consistent application of a disciplined financial model. Built on a foundation of innovation, we are relentless in our pursuit of excellence, aligning our team members, operations, systems of oversight and financial metrics to create a high performance, accountable organization with an engaged workforce deeply passionate about helping to create the products that build a better world. Financial Model Our primary long-term goal is to achieve a 9-12% compounded annual revenue growth rate while earning a return on invested capital ("ROIC") of 15%, which would significantly exceed our weighted average cost of capital ("WACC") and represent positive economic return. Economic return is the amount by which our ROIC exceeds our WACC, and we believe it is a fundamental driver of shareholder value. We review our internal calculation of WACC annually; for fiscal 2025, our WACC was 8.9%. For more information regarding ROIC and economic return, which are non-GAAP financial measures, refer to "Management’s Discussion and Analysis of Financial Condition - Results of Operations - Return on Invested Capital ("ROIC") and economic return" in Part II, Item 7. For additional information on our use of non-GAAP financial measures, see Exhibit 99.1 to this annual report on Form 10-K, which exhibit is incorporated herein by reference.
