This report may contain forward-looking statements within the
meaning of the federal securities laws, including Section 27A of
the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. In this context,
forward-looking statements often address expected future business
and financial performance and financial condition, and often
contain words such as expect, anticipate, intend, plan, believe,
seek, see, will, would, target, similar expressions, and
variations or negatives of these words. Forward-looking
statements by their nature address matters that are, to different
degrees, uncertain, such as statements about the consummation of
the proposed transaction and the anticipated benefits thereof.
These and other forward-looking statements, including the failure
to consummate the proposed transaction or to make or take any
filing or other action required to consummate such transaction on
a timely matter or at all, are not guarantees of future results
and are subject to risks, uncertainties and assumptions that
could cause actual results to differ materially from those
expressed in any forward-looking statements. Important risk
factors that may cause such a difference include, but are not
limited to, (i) the completion of the proposed transaction on
anticipated terms and timing, including obtaining shareholder and
regulatory approvals, anticipated tax treatment, unforeseen
liabilities, future capital expenditures, revenues, expenses,
earnings, synergies, economic performance, indebtedness,
financial condition, losses, future prospects, business and
management strategies for the management, expansion and growth of
the new combined companys operations and other conditions to the
completion of the merger, (ii) the ability of Knight and Swift to
operate the business successfully and to achieve anticipated
synergies, (iii) potential litigation relating to the proposed
transaction that could be instituted against Knight, Swift or
their respective directors, (iv) the risk that disruptions from
the proposed transaction will harm Knight’s or Swift’s
business, including current plans and operations, (v) the ability
of Knight and Swift to retain and hire key personnel, (vi)
potential adverse reactions or changes to business relationships
resulting from the announcement or completion of the merger,
(vii) uncertainty as to the long-term value of the combined
company’s common stock, (viii) continued availability of capital
and financing and rating agency actions, (ix) legislative,
regulatory and economic developments, and (x) unpredictability
and severity of catastrophic events, including, but not limited
to, acts of terrorism or outbreak of war or hostilities, as well
as managements response to any of the aforementioned factors.
These risks, as well as other risks associated with the proposed
merger, will be more fully discussed in the joint proxy
statement/prospectus that will be included in the registration
statement on Form S-4 that will be filed with the SEC in
connection with the proposed merger. While the list of factors
presented here is, and the list of factors to be presented in the
registration statement on Form S-4 are, considered
representative, no such list should be considered to be a
complete statement of all potential risks and uncertainties.
Unlisted factors may present significant additional obstacles to
the realization of forward-looking statements. Consequences of
material differences in results as compared with those
anticipated in the forward-looking statements could include,
among other things, business disruption, operational problems,
financial loss, legal liability to third parties and similar
risks, any of which could have a material adverse effect on
Knight-Swift financial condition, results of operations, credit
rating or liquidity. Neither Knight nor Swift assumes any
obligation to publicly provide revisions or updates to any
forward looking statements, whether as a result of new
information, future developments or otherwise, should
circumstances change, and any such obligation is specifically
