                                   (unaudited)


Note 1. Basis of Presentation

        The condensed  consolidated financial statements include the accounts of
        Swift  Transportation  Co.,  Inc.,  a Nevada  holding  company,  and its
        wholly-owned  subsidiaries (the Company).  All significant  intercompany
        balances and transactions have been eliminated.

        The financial statements have been prepared in accordance with generally
        accepted accounting principles, pursuant to rules and regulations of the
        Securities and Exchange  Commission.  In the opinion of management,  the
        accompanying  financial  statements  include all  adjustments  which are
        necessary for a fair presentation of the results for the interim periods
        presented.  Certain  information  and  footnote  disclosures  have  been
        condensed  or  omitted  pursuant  to such rules and  regulations.  These
        condensed  consolidated financial statements and notes thereto should be
        read in conjunction with the consolidated financial statements and notes
        thereto  included in the  Company's  Annual  Report on Form 10-K for the
        year ended December 31, 1997.  Results of operations in interim  periods
        are not  necessarily  indicative  of results to be  expected  for a full
        year.

Note 2. Contingencies

        The Company is involved in certain claims and pending litigation arising
        from the normal course of business.  Based on the knowledge of the facts
        and, in certain cases, opinions of outside counsel,  management believes
        the resolution of claims and pending litigation will not have a material
        adverse effect on the financial condition of the Company.

Note 3. Stock Split

        On February  20,  1998,  the  Company's  Board of  Directors  approved a
        3-for-2 stock split effected in the form of a stock dividend and payable
        on March 12, 1998 to the stockholders of record at the close of business
        on March 2, 1998. All share amounts, share prices and earnings per share
        have been retroactively adjusted to reflect this 3-for-2 stock split.

Note 4. Line of Credit

        In August  1998,  the  Company  modified  its  unsecured  line of credit
        agreement to increase the maximum available borrowings from $110 million
        to $170 million and extend the maturity to January 16, 2003.

YEAR 2000 ISSUE

The Company is in the process of performing a  comprehensive  review of its Year
2000  issues  and  has  completed  its  initial   review  of  internal   systems
(information  technology  ("IT") and  non-IT).  The  majority  of the  Company's
application  software  programs are  purchased  from and  maintained by vendors.
Therefore,  the Company is working with these  software  vendors to verify these
applications  become Year 2000  compliant.  The Company  estimates the status of
progress of these internal systems as follows:

                             Vendor Modifications      Testing Commenced
                               Being Performed

IT Systems                          85%                      20%

Non-IT Systems                      70%                      15%

The Company presently  believes that with  modifications and updates to existing
software,  the cost of which  is not  expected  to be  material,  the Year  2000
problem  will  not  pose  significant  operational  problems  for the  Company's
internal systems.

                                       10


As part of the Company's  comprehensive  review,  it is continuing to verify the
Year 2000  readiness  of third  parties  (vendors and  customers)  with whom the
Company  has  material  relationships.  At  present,  the Company is not able to
determine  the effect on the Company's  results of  operations,  liquidity,  and
financial  condition in the event the Company's  material  vendors and customers
are not Year 2000  compliant.  The Company will continue to monitor the progress
of its material  vendors and customers and formulate a contingency  plan at that
point in time when the Company  does not  believe a material  vendor or customer
will be compliant.

OVERVIEW

Although the trend in the truckload  segment of the motor carrier  industry over
the past several years has been towards  consolidation,  the truckload  industry
remains  highly  fragmented.  Management  believes  the industry  trend  towards
financially  stable  "core  carriers"  will  continue  and  result in  continued
industry  consolidation.  In response to this trend,  the Company  continues  to
expand  its fleet with an  increase  of 788  tractors  to 6,578  tractors  as of
September 30, 1998 up from 5,790  tractors as of September  30, 1997.  The owner
operator  portion of the Company's  fleet increased to 1,166 as of September 30,
1998 from 848 as of September 30, 1997.


RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO 
THREE MONTHS ENDED SEPTEMBER 30, 1997

Operating  revenue  increased  $39.1 million or 20.8% to $227.2  million for the
three months ended September 30, 1998 from $188.1 million for the  corresponding
period of 1997. The increase in operating revenue is primarily the result of the
expansion  of the  Company's  fleet as a result of strong  shipper  demand.  The
Company's  freight rates  increased by  approximately 2% in the third quarter of
1998 compared to the third quarter of 1997.

The Company's  operating ratio (operating  expenses expressed as a percentage of
operating  revenue) for the third quarter of 1998 was 88.0% compared to 87.9% in
the  comparable  period of 1997.  The  Company's  operating  ratio for the three
months ended  September  30, 1998  increased as a result of increases in certain
components  of  operating  expenses  as a  percentage  of  operating  revenue as
discussed  below.  The Company's  empty mile factor for linehaul  operations was
13.2% and 13.1% and  average  loaded  linehaul  revenue  per mile was $ 1.32 and
$1.30 in the third quarter of 1998 and 1997, respectively.

Salaries, wages and employee benefits represented 37.1% of operating revenue for
the three months  ended  September  30, 1998  compared  with 34.4% in 1997.  The
increase is primarily due to an increase in workmen's compensation,  the accrual
for the  Company's  profit  sharing  contribution,  normal  wage  increases  and
associated benefits and taxes.

From time to time the industry has experienced  shortages of qualified  drivers.
If such a shortage were to occur over a prolonged period and increases in driver
pay rates were to occur in order to attract and retain  drivers,  the  Company's

                                       11


results  of  operations  would  be  negatively   impacted  to  the  extent  that
corresponding rate increases were not obtained.

Fuel as a  percentage  of operating  revenue was 10.2% for the third  quarter of
1998 versus 11.8% in 1997.  The decrease is partially  due to an increase in the
number of owner  operators who are  responsible for their own fuel. In addition,
actual fuel cost per gallon  decreased by  approximately  13 cents per gallon in
the third quarter of 1998 versus the third quarter of 1997.

Increases  in fuel  costs,  to the extent not offset by rate  increases  or fuel
surcharges,  could have an adverse effect on the operations and profitability of
the Company. Management believes the most effective protection against fuel cost
increases is to maintain a fuel efficient fleet and to implement fuel surcharges
when such option is necessary and available.  The Company currently does not use
derivative-type hedging products but is currently evaluating the possible use of
these products.

Purchased  transportation as a percentage of operating revenue was 14.9% for the
three months ended September 30, 1998 compared to 13.6% in 1997. The increase is
due to the growth of the owner  operator fleet to 1,166 as of September 30, 1998
from 848 as of September 30, 1997.

Rental  expense as a  percentage  of  operating  revenue  was 4.9% for the third
quarter of 1998  versus 6.3% in 1997.  At  September  30, 1998 and 1997,  leased
tractors  represented 54% and 63%,  respectively,  of the total fleet of Company
tractors.  In addition to the reduction in the percentage of tractors which were
leased,  rental expense was positively  impacted by a reduction in the number of
leased  trailers as well as a slight  reduction  in the  average  lease rate for
tractors in the third quarter of 1998 versus the third quarter of 1997.  When it
is  economically  advantageous  to do so, the Company  will  purchase  then sell
tractors that it currently leases by exercising the purchase option contained in
the  lease.  Gains on these  activities  are  recorded  as a  reduction  of rent
expense.  The Company recorded $223,000 in the third quarter of 1998 and no gain
during the third quarter of 1997 from the sale of leased tractors.

Depreciation and amortization  expense as a percentage of operating  revenue was
4.9% in the third  quarter of 1998  versus 5.2% in 1997.  The  Company  includes
gains and losses from the sale of owned revenue  equipment in  depreciation  and
amortization  expense.  During the three month period ended  September 30, 1998,
net  gains  from  the  sale  of  revenue  equipment  reduced   depreciation  and
amortization  expense by  approximately  $2.1 million  compared to approximately
$1.1 million in the third  quarter of 1997.  Exclusive of gains,  which  reduced
this expense, depreciation and amortization expense as a percentage of operating
revenue was 5.8% in the third quarter of 1998 and 1997.

Insurance and claims expense  represented 2.9% and 2.5% of operating  revenue in
the  third  quarter  of 1998 and 1997,  respectively.  The  Company's  insurance
program for liability,  physical damage and cargo damage involves self-insurance
with varying risk  retention  levels.  Claims in excess of these risk  retention
levels are covered by insurance in amounts which management  considers adequate.
The  Company  accrues the  estimated  cost of the  uninsured  portion of pending
claims.  These accruals are estimated  based on  management's  evaluation of the

                                       12


nature and  severity  of  individual  claims and an  estimate  of future  claims
development based on historical claims development trends.

NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO
NINE MONTHS ENDED SEPTEMBER 30, 1997

Operating  revenue  increased  $109.6 million or 20.9% to $634.6 million for the
nine months ended  September 30, 1998 from $525.0 million for the  corresponding
period of 1997. The increase in operating revenue is primarily the result of the
expansion of the Company's fleet and rate increases.

The Company's  operating ratio (operating  expenses expressed as a percentage of
operating revenue) for the first nine months of 1998 was 89.1% compared to 89.9%
in the  comparable  period of 1997. The Company's  operating  ratio for the nine
months  ended  September  30, 1998  improved  as a result of the  aforementioned
increase in operating  revenue combined with decreases in certain  components of
operating  expenses as a percentage of operating revenue as discussed below. The
Company's  empty mile  factor for  linehaul  operations  was 13.6% and 13.9% and
average loaded  linehaul  revenue per mile was $1.32 and $1.30 in the first nine
months of 1998 and 1997, respectively.

Salaries, wages and employee benefits represented 36.2% of operating revenue for
the nine months  ended  September  30,  1998  compared  with 35.0% in 1997.  The
increase is primarily due to an increase in the accrual for the Company's profit
sharing  contribution  and normal wage  increases  and  associated  benefits and
taxes.

Fuel as a percentage of operating revenue was 10.9% for the first nine months of
1998 versus  12.9% in 1997.  The decrease is due to an increase in the number of
owner operators who are responsible for their own fuel and the reduction in fuel
prices as discussed above.

Purchased  transportation as a percentage of operating revenue was 15.4% for the
nine months ended  September 30, 1998 compared to 13.2% in 1997. The increase is
due to the growth of the owner  operator fleet to 1,166 as of September 30, 1998
from 848 as of September 30, 1997.

Rental expense as a percentage of operating  revenue was 4.8% for the first nine
months of 1998 versus 6.7% in 1997. When it is  economically  advantageous to do
so, the Company will purchase  then sell  tractors  that it currently  leases by
exercising the purchase option contained in the lease. Gains on these activities
are recorded as a reduction of rent expense.  The Company  recorded $2.7 million
in 1998 and no gain during the first nine months of 1997 from the sale of leased
tractors.  As discussed above, rental expense decreased in the first nine months
of 1998  versus  1997 as a result of a  reduction  in the  percentage  of leased
tractors,  number of leased  trailers and the average  lease rate for  tractors.

Depreciation and amortization  expense as a percentage of operating  revenue was
5.2% in the first nine months of 1998 versus 5.3% in 1997. The Company  includes
gains and losses from the sale of owned revenue  equipment in  depreciation  and
amortization expense. During the nine month period ended September 30, 1998, net
gains from the sale of revenue equipment  reduced  depreciation and amortization
expense by approximately  $4.6 million compared to approximately $2.9 million in
the first nine months of 1997.  Exclusive of gains,  which reduced this expense,

                                       13


depreciation and amortization  expense as a percentage of operating  revenue was
5.9% and 5.8% in the first nine months of 1998 and 1997, respectively.

Insurance and claims expense  represented 3.0% of operating revenue in the first
nine months of 1998 and 1997.  The Company's  insurance  program for  liability,
physical  damage and cargo  damage  involves  self-insurance  with  varying risk
retention levels. Claims in excess of these risk retention levels are covered by
insurance in amounts which management  considers  adequate.  The Company accrues
the estimated cost of the uninsured  portion of pending  claims.  These accruals
are  estimated  based on  management's  evaluation of the nature and severity of
individual  claims  and an  estimate  of  future  claims  development  based  on
historical claims development trends.

LIQUIDITY AND CAPITAL RESOURCES

The continued growth in the Company's business requires  significant  investment
in new  revenue  equipment,  upgraded  and  expanded  facilities,  and  enhanced
computer  hardware and  software.  The funding for this  expansion has been from
cash  provided  by  operating  activities,  proceeds  from the  sale of  revenue
equipment,  long-term debt,  borrowings on the Company's line of credit, the use
of operating  leases to finance the  acquisition  of revenue  equipment and from
periodic public offerings of common stock.

Net cash  provided by operating  activities  was $98.7 million in the first nine
months of 1998  compared to $57.7  million in 1997.  The  increase is  primarily
attributable  to an increase  in net  earnings  and  accounts  payable,  accrued
liabilities and claims accruals.

Prepaid  expenses  increased by $1.7 million from December 31, 1997 to September
30, 1998. The increase is primarily due to significant annual license fees which
are prepaid in the first quarter of each year and  amortized  over the remainder
of the year.

Net cash used in investing  activities  increased to $116.7 million in the first
nine months of 1998 from $83.0 million in 1997. The increase is due primarily to
greater  capital  expenditures  and treasury  stock  purchases in 1998 offset by
increased proceeds from the sale of property and equipment and payments received
on equipment  sales  receivable  in 1998 along with a reduction in cash expended
for Direct Transit, Inc. assets in 1997.

As of September 30, 1998,  the Company had  commitments  outstanding  to acquire
replacement and additional revenue equipment for approximately $243 million. The
Company  has the option to cancel  such  commitments  upon 60 days  notice.  The
Company  believes  it has the  ability to obtain  debt and lease  financing  and
generate  sufficient  cash  flows from  operating  activities  to support  these
acquisitions of revenue equipment.

During the first nine months of 1998, the Company incurred  approximately  $18.5
million of non-revenue equipment capital  expenditures.  These expenditures were
primarily for facilities and equipment.

                                       14


The Company anticipates that it will expend approximately $10 million during the
remainder  of the year for  various  facilities  upgrades  and  acquisition  and
development of terminal facilities.  Factors such as costs and opportunities for
future terminal expansions may change the amount of such expenditures.

The funding for capital  expenditures has been and is anticipated to continue to
be  from a  combination  of  cash  provided  by  operating  activities,  amounts
available under the Company's line of credit and debt and lease  financing.  The
availability  of capital for revenue  equipment and other  capital  expenditures
will be affected by prevailing  market  conditions  and the Company's  financial
condition and results of operations.

Net cash provided by financing activities amounted to $16.6 million in the first
nine  months  of 1998  compared  to $34.1  million  in 1997.  This  decrease  is
primarily due to reduced borrowings under the line of credit.

Management  believes it will be able to finance  its needs for working  capital,
facilities  improvements  and  expansion,  as well as  anticipated  fleet growth
through a combination of revenue equipment purchases and strategic acquisitions,
as  opportunities  become  available,  with cash flows from  future  operations,
borrowings  available  under  the line of  credit  and with  long-term  debt and
operating lease financing  believed to be available to finance revenue equipment
purchases.  Over the long term,  the Company will  continue to have  significant
capital  requirements,   which  may  require  the  Company  to  seek  additional
borrowings  or equity  capital.  The  availability  of debt  financing or equity
capital  will  depend  upon the  Company's  financial  condition  and results of
operations  as well as  prevailing  market  conditions,  the market price of the
Company's common stock and other factors over which the Company has little or no
control.

INFLATION

Inflation can be expected to have an impact on the Company's  operating costs. A
prolonged period of inflation would cause interest rates,  fuel, wages and other
costs to increase and would adversely affect the Company's results of operations
unless freight rates could be increased correspondingly.  However, the effect of
inflation has been minimal over the past three years.

SEASONALITY

In the transportation industry,  results of operations generally show a seasonal
pattern as customers  reduce  shipments  after the winter  holiday  season.  The
Company's  operating  expenses  also  tend to be  higher  in the  winter  months
primarily  due to colder  weather  which  causes  higher fuel  consumption  from
increased idle time.
