Film & Electrolytics Restructuring Campaign

Film & Electrolytic Capacitors Restructuring will be completed during the second half of FY2014. The expectation is that F&E will become a positive contributor to our financial results by Q3 FY 2014. However, our evaluation of the future of the Film & Electrolytic business remaining a part of the KEMET family involves the following: Where we are in the current Business Cycle Where we are in terms of restructuring this business and the financial return from these efforts Our view of the current and future prospects for Film and Electrolytic capacitors

Business Cycle Below is a historical quarterly view of the Film and Electrolytic Capacitor market in terms of value which illustrate the last two cycles . The swings (high to low) in purchasing of these two types of capacitors are dramatic (-50%, +100%).

Business Cycle Objective: Take advantage of cyclical increase Sell our capabilities to initiate the timing of the increase Restructure our business so we can be profitable during the valleys as well as in the peaks.

Restructuring During fiscal years 2011 and 2012, the Film & Electrolytic Capacitor Business Group generated ~$78MM in Segment Operating Profit. Approximately 15% EBIT margin. Since the previous peak period, we have reduced Film & Electrolytic Capacitor operating costs by ~$15M on an annual basis. A summary of the activities that generated these savings are: #Line Moves 31 #Plant Closing(s) 2 #People moved from HLCC to LLCC 211 During FY14, costs are expected to be reduced by another $17 million and $7 million additional savings in FY2015. This will be accomplished by executing the following actions: #Line Moves 34 #Plant Closing(s) 3 #Labor relocations 197

Restructuring Plan Line Move Summary

Restructuring Continued: The two key initiatives for FY14 restructuring are: Creation of Lower Labor Cost Plants to support Europe and America: Skopje, Macedonia for Film Capacitors Evora, Portugal for Electrolytic Capacitors Consolidate three Italy Film plants into a single plant: Monghidoro, Italy operation for Film capacitor has ceased Vergato, Italy will be moved into Pontecchio, Italy facility in FY14 Sasso Marconi, Italy will be moved into Pontecchip, Italy facility in FY14 Maintain Asian Plants to support Asia and America: Anting, China and Batam, Indonesia for Film Capacitors Suzhou, China for Electrolytic Capacitors

Product Capabilities Main uses of Film & Electrolytic capacitors: Motors Drives Power Supplies Voltage Conversion Circuits Power Meters Voltage / Pulse Suppression Power Factor Correction Film capacitors have a unique self-healing characteristic which prevents them from failing in a catastrophic way when the materials, process, and design are properly engineered. This provides opportunity for many safety applications where a fail safe mechanism is required. In addition, packages can also be engineered to provide a fail safe solution. These capabilities are needed now and will continue to be needed in the future.

 One of our strengths is our ability to design products to meet unique customer requirements for use in the following markets: Automotive Industrial Drives/Motors Wind Power Solar Power Medical Devices Lighting Electrical Distribution and Measurement As we restructure our manufacturing operations, we are keeping our R&D centers close to our customer’s to maintain this competitive advantage.
