As we enter the 2nd quarter of 2023, the global economy and the automotive industry are forecast to weaken. Automotive OEMs (Ford, GM, etc.) are still being affected by component shortages and are beginning to reduce production as their inventory levels grow. Summit’s team performance remains strong and we are focused on improvement. This year we are focusing on “back to the basics”. I’m looking forward to working with all of you this year!

How Summit Succeeds in a Very Competitive Business As introduced in the President’s message, this year we are focused on improvement and “back to the basics”. This means each of us, every day executing, our core, standard systems and processes. This approach will guide us in four areas of improvement.

1. Operational excellence in our manufacturing plants and achieving our operational targets related to safety, quality, delivery, and cost 2. Material cost reduction from our supply base and through value added activities 3. Cost control in the plants and the tech center – carefully watch our spending 4. Logistics and inventory cost reduction And, as always, please keep front and center in thinking and actions our Summit Lean Manufacturing Philosophy: Safety Zero injuries Customer focus Zero defects 100% value added processes and systems 100% on time, 1×1 in sequence People are the most valuable resources Motivated and capable people drive organizational success Standardized work, problem solving, and continuous improvement define our culture Intellectually challenging work provides growth opportunities and job security Continuous Improvement (Kaizen) Built upon a foundation of standards and stability Focused on eliminating waste from all systems and processes Focused on challenging ourselves to find a better way in everything we do, every single day Centered on staying ahead of our competition Shop Floor Focus (“Go and See”)

I grew up in metro Detroit and received my bachelor’s degree from The University of Michigan in Industrial and Operations Engineering and then my master’s degree in Engineering Management.

For my first couple of assignments after college I was doing what Summit Polymers would call SLMS Engineering, but then I landed in Supplier Development Engineering. That started my career progression on the Procurement pathway, and it has remained there ever since. I have spent the last 25 years at different Tier 1 automotive powertrain systems suppliers (BorgWarner, Eaton, Dana and Meritor).

Prior to hiring into Summit Polymers, I spent 11 years with Meritor (formerly Rockwell and ArvinMeritor) leading the North and South American Procurement organization for their Commercial Vehicle Systems division.

It’s difficult for me to believe that it has already been almost two years since I started at Summit Polymers and moved my family to the Kalamazoo area. Starting a new supply chain job in the middle of the COVID pandemic proved to be challenging for many reasons. There were obviously a lot of raw material shortages we were managing. There were supplier bankruptcies also. The most difficult part, however, was the fact that not everyone was in person in the office for my first couple of months. Zoom meeting fatigue was a real thing and I was enthusiastic when everyone got back to the office in mid-June 2021.

The Summit Polymers Corporate Purchasing and Materials team includes the following functions that support our Global Operations: Purchasing – Quoting, Sourcing and Launching Suppliers (Key KRAs: Cost Reduction, Supplier Delivery, RFQ timeliness), Materials Systems - Supporting Plant Materials as a Center of Excellence (Key KRAs: Material Systems Audits, KBPD Gate Reviews, Inventory Days on Hand), Supplier Development Engineering – Monitoring and Improving Supplier Performance (Key KRAs: Supplier Incidences, PPAP timeliness, Supplier Delivery), Logistics – Improving Freight Costs and Managing our Warehouse Operations (Key KRAs: Freight Cost, Inventory Days on Hand, Truckload Utilization).

I spent my first several months with Summit Polymers visiting all North American manufacturing sites and getting feedback on what the Corporate Purchasing and Materials teams were doing well and what could be improved. This feedback allowed me to understand several themes that have been prioritized for our team: Systems Refinement & Process Automation, Global Commodity Strategies – emphasis on soft trim and stampings, Improving Supplier Launch Performance and Localization of Supply in Mexico.

Heading into 2023 and beyond, our Corporate Purchasing and Materials team is focused on finding sustainable cost reductions from our supply base, supporting new program launches, optimizing our inventory and freight costs, and improving and simplifying our many materials systems.

Kris Tewkesbury – Vice President of Purchasing and Supply Chain

Cliff now serves as head of Engineering Department, he leads a team who provides in time response to production needs by identifying opportunities for improvement, innovation and articulating the ways to solve the problems.

Filiberto Laguna, Forklift Driver, P17 Filiberto has a great attendance record, meets 100% of his responsibilities in receiving area, works and collaborates with other departments. His service attitude is excellent. Filiberto is committed to plan work requirements and safety internal rules.

Josh Borton, Assembly Utility, P18 Josh comes in daily to get his job done and support his team members as needed so we meet our goals. Josh is an asset to his team and to Summit Polymers Plant 18. No matter what is asked of him, he is open minded and more than willing to go above and beyond for us to be successful. If there's a better way to meet the goal Josh will communicate that to us all and continue striving for us to satisfy our customers.

To Huy Du, Assembly Supervisor, P19 Du is an enthusiastic colleague who is always looking for improvement opportunities in his department. He identified an ergonomic kaizen on S650 to help operators assemble the knob without straining their wrists and reduce CT by 1 second .
