Thank you again for your partnership and welcome to Superior.

This strategic acquisition is a great strategic step forward for all of us. By combining our strengths, we’re expanding our global reach, deepening our technical expertise, and enhancing our ability to serve customers with speed, precision, and innovation. Sonic Connectors legacy, talent, and proprietary technologies will expand the Superior product offering to our existing customers across our global footprint. Together, we’re better positioned to adapt to evolving industry conditions and deliver smarter, more responsive solutions.

In the near term, Sonic Connectors will continue to operate under its current brand and structure. We want to preserve what makes Sonic special while identifying opportunities to integrate and grow together. 

Brody Whitely will continue to lead Sonic and will report to Bryan Ellis, Division President of Wellsite Solutions. This structure ensures continuity and supports a thoughtful integration process.

As with any acquisition and integration, certain business processes and practices within the two organizations will need to be consolidated. We ask for your support and cooperation with our integration teams as they work to align the two systems. Their goal is to create a unified platform that benefits both our employees and our customers. 

Your supervisors will continue to communicate with you regarding progress and key integration updates. Updates on integration progress will also be shared via email and text.

Employees are encouraged to contact their direct supervisors and HR leaders for immediate questions and concerns. Superior will update employees via email and text messaging regarding integration activities as they are executed.

We are looking forward to combining two great organizations and our goal is to retain top talent to maximize the potential of the combined organization. Retention of Sonic’s talented workforce is critical to the success of the integration into Superior. We aim to retain all Sonic employees and offer opportunities for career growth and geographic relocations.  

The addition of Sonic to Superior’s Wellsite Solutions segment brings valuable technology, products, facilities, and talented employees that further strengthen our ability to serve customers throughout the well lifecycle. As integration planning progresses, we will evaluate organizational structures, roles, and responsibilities across both organizations to ensure we are positioned to support future growth and maximize the combined strengths of the business. 

There are no anticipated job cuts related to the integration of Sonic into Superior. Our goal is to expand the Sonic business into other regions and create growth opportunities for our team members. We’re committed to sharing these opportunities by providing open dialogue and regular updates. 

Your current pay and benefits will largely remain unchanged. One key update is your transition from the Sonic 401K and benefits plans to the Superior 401(k) and benefits plans, which you'll be eligible for shortly after integration. There may be a brief period when 401(k) contributions are paused. More details on this and the full transition to Superior's payroll and benefits will be shared in the coming weeks.

There should be little to no change.

We will honor your tenure with Sonic to determine your PTO levels. Your current vacation and other leave benefits are currently being evaluated and will be communicated with more details of your transition to becoming a Superior employee.

The organizational structure will initially remain the same for most employees. As we evaluate where there are opportunities to expand our operations and solidify our ability to deliver value to our customers, we will continue to communicate regularly regarding growth opportunities and/or organizational changes. 

Initially, there will be minimal change.  There will be future communication as opportunities arise to possibly move individuals and teams.  Our goal is to develop a structure and define roles that create the greatest opportunity for our employees to be successful. 

There is no plan currently for relocation to new offices.

That will be evaluated in the event relocations would be required.

We are excited about the potential of these two organizations coming together. We recognize that there are great things about both companies and teams and hope to find the best of both as we move forward in the consolidation. At Superior, we embrace our Shared Core Values and focus on a belief that how we run our business contributes to our overall success. This is what sets us apart as a fair employer, a trusted business partner, and a good corporate citizen.
