Full Anouncement Letter

April 10, 2017
Dear Swift Owner/Operator:
This morning, we announced that Swift Transportation and Knight Transportation have reached an
agreement to operate under common ownership. Both companies will continue to run independently and
will maintain separate brands. Bringing together these two long-standing, industry-leading trucking
companies means a combined strength of resources, allowing us to improve safety and better our
customer and driver experiences. The joint press release we issued this morning provides further details
about the transaction. It is now available, along with FAQs, on our O/O portal and on our website.
Swift is offering an Independent Contractor Capacity Retention Bonus to all eligible Swift independent
contractors in recognition of your commitment to the success of this business. Those eligible will include
all independent contractors with active ICOAs – Independent Contractor Operating Agreements –
between May 1, 2017 and the close of the transaction. It is anticipated the transaction will close in the
third quarter of 2017. Please see Independent Contractor Capacity Retention Bonus letter for more
details.
Also, I want you to know that I have chosen to pursue other opportunities following the close of the
transaction. Likewise, our CFO, Ginnie Henkels, has chosen to step down at that time. I want to assure
you that Knight’s leadership team is committed to the same principles and level of integrity that we live by
every day, and I have confidence that they will continue working toward our vision.
Once the transaction is completed, Kevin Knight, Knight’s current Executive Chairman, will assume the
role of Swift President. Ginnie and I will continue at Swift until the close of the transaction to ensure a
seamless transition. I’m proud of all we have accomplished together, and promise that I will continue to
root all of you on in the future.
For the sake of open communication and transparency, I invite all of you to join Ginnie and me on a
Company-wide conference call, this afternoon, at 4:30 PM (ET)/1:30 PM (PT). The call-in number is (844)
236-5642, in the U.S., and (562) 508-4617, outside the U.S. The event passcode is 4785913.
To maximize efficiency, I will address the organization and then answer your pre-submitted questions.
Please submit all questions in the form of an email to AskRichard@Swifttrans.com, prior to 3:00 PM
(ET)/12:00 PM (PT), today. That will allow me to answer as many questions as possible.
If you receive any questions from other Independent Contractors, please refer them to the press release
on our website or have them email communications@Swifttrans.com.
I thank you for your continued hard work and dedication to SWIFT and I want you to know that I am
confident that SWIFT’s future holds even greater opportunities for you, in the future.
Sincerely,
Richard Stocking
President & CEO
