EXHIBIT 99

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

ANNOUNCES UPDATED EARNINGS GUIDANCE

PHOENIX, ARIZONA – January 17, 2019 – Knight-Swift Transportation Holdings Inc. (NYSE: KNX) today announced updates to its earnings guidance for the fourth quarter of 2018 and the first quarter of 2019 and announced earnings guidance for the second quarter of 2019.

• Based on preliminary results, the company now expects Adjusted EPS for the fourth quarter of 2018 will range from $0.91 to $0.93 (which is an update from the previously announced expectation of $0.71 to $0.75).

• The company now expects Adjusted EPS for the first quarter of 2019 will range from $0.52 to $0.55 (which is an update from the previously announced expectation of $0.50 to $0.54).

• The company expects Adjusted EPS for the second quarter of 2019 will range from $0.62 to $0.66.

Adjusted EPS reflects US GAAP diluted earnings per share after adding back the after-tax impact of intangible amortization expense, impairments, and severance expense associated with certain organizational changes at Swift.

The updates to the expected Adjusted EPS range for the fourth quarter of 2018 and first quarter of 2019 are based on several factors that positively affected earnings across the company's reportable segments, including increases in revenue per loaded mile, excluding fuel surcharge, improved safety results, lower fuel costs, and meaningful improvements in the adjusted operating ratios across the Swift reportable segments.

Knight-Swift Transportation Holdings Inc. is a provider of multiple truckload transportation and logistics services using a nationwide network of business units and terminals in the United States and Mexico to serve customers throughout North America. In addition to operating North America's largest tractor fleet, Knight-Swift also contracts with third-party equipment providers to provide a broad range of truckload services to its customers while creating quality driving jobs for our driving associates and successful business opportunities for independent contractors.
