Expansive New Building Accommodates Office and State-of-the-Art Manufacturing

To accommodate current and future growth, Extreme Engineering Solutions (X-ES) has moved to a new corporate headquarters in Verona, WI. Completed in September 2018, the combined office and manufacturing space is located at 9901 Silicon Prairie Parkway, approximately six miles from the company’s previous headquarters in Middleton, WI.

The new 126,200 sq. ft. facility is a significant upgrade from the 50,000 sq. ft. Middleton facility, offering more office space and improved amenities for employees and customers, including more than twice the meeting space.

The design by KEE Architecture features a central atrium and clerestory windows that provide abundant natural light to offices and common areas. The building is situated on 13.8 acres, leaving ample room to grow as the company expands.

Significantly enlarged manufacturing and production space


Nearly half of the new facility is devoted to a state-of-the-art manufacturing space, where X-ES performs final product assembly, integration, and testing.

The 60,000 sq. ft. manufacturing area is temperature-, humidity-, and ESD-controlled, and approximately four times larger than the Middleton manufacturing space. As part of this expansion, X-ES has acquired 165 new workbenches, six new thermal chambers for temperature testing, and one new shaker for shock and vibration testing.

Focused on energy-conscious design and equipment


To achieve ambitious goals for long-term energy savings, X-ES worked with the Wisconsin Focus on Energy Business Incentive Program to incorporate equipment and practices that reduce energy waste, such as network lighting controls and energy-efficient heating and cooling equipment.

The estimated electricity savings over the life of the equipment is more than eight million kilowatt hours, and the estimated lifecycle natural gas savings equates to almost 49,000 gallons of gasoline.

New facility, but still the same X-ES

X-ES continues to engage third-party contractors for printed circuit board (PCB) fabrication and assembly. Those facilities have not changed with this move. X-ES operations remain 100% US-based, with all products designed, manufactured, tested, and supported in the United States.

ISO 9001:2015 certification for the new facility was completed on October 10, 2018.

Frequently Asked Questions


What is the reason behind the move?

The move is driven by growth. X-ES has outgrown the space of their current facility and decided to build a new facility to support their current and future needs. The new facility contains both office and manufacturing space. It is roughly 2.5x the size of their current facility.

Where are you moving to?

X-ES' current facility is located in Middleton, WI and they are moving to Verona, WI. It is approximately 5 miles between the current and new facility.

Are you going to operate out of both facilities?

This move is a full transition to the new facility. XES will not operate out of the old facility once the move is completed.

Does this move impact/change SMT assembly?

The move only affects the final assembly, integration, and test work that X-ES does. SMT assembly is done out of house and those facilities are not changing with this move.

How does this impact shipments?

All shipments scheduled prior to the move date (planned for September 7, 2018) will occur at the current facility.

After the move, there will be a two week blackout period where shipments will not occur as X-ES completes the necessary setup, calibration, and quality checks. Once that is complete, we will work with each customer to support and facilitate the necessary audits and/or compliance checks that are required in order to resume shipments to that customer.

Will this move impact pricing?

There will be no changes in pricing resulting from this move.

How does this impact development programs?

For the design collaboration effort with our customers, the impact of this move should be little to none as it will occur outside of normal working hours. All contact information and mechanisms will remain the same.
