                             HEARTLAND EXPRESS, INC.
                                AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1.  Basis of Presentation

     The accompanying  unaudited  consolidated financial statements of Heartland
Express,  Inc. and subsidiaries (the "Company") have been prepared in accordance
with generally accepted accounting  principles for interim financial information
and with the instructions to Form 10-Q and Regulation S-X. Accordingly,  they do
not include all of the information and footnotes  required by generally accepted
accounting  principles  for  complete  financial  statements.  In the opinion of
management,  all normal,  recurring adjustments  considered necessary for a fair
presentation  have been  included.  The financial  statements  should be read in
conjunction  with the audited  consolidated  financial  statements  for the year
ended  December  31,  2005  included  in the  Annual  Report on Form 10-K of the
Company filed with the Securities and Exchange  Commission.  Interim  results of
operations are not necessarily  indicative of the results to be expected for the
full year or any other interim  periods.  There were no changes to the Company's
significant accounting policies during the quarter.

Note 2.  Use of Estimates

     The preparation of financial  statements in conformity with U.S.  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Note 3.  Segment Information

     The Company has ten operating divisions; however, it has determined that it
has one  reportable  segment.  All of the divisions are managed based on similar
economic  characteristics.  Each of the regional  operating  divisions  provides
short-to  medium-haul  truckload  carrier  services of general  commodities to a
similar  class  of  customers.  In  addition,  each  division  exhibits  similar
financial  performance,  including average revenue per mile and operating ratio.
As a result of the foregoing,  the Company has determined that it is appropriate
to aggregate its operating  divisions  into one reportable  segment,  consistent
with the guidance in SFAS No. 131.  Accordingly,  the Company has not  presented
separate  financial  information  for  each of its  operating  divisions  as the
Company's consolidated financial statements present its one reportable segment.

Note 4.  Cash and Cash Equivalents

     Cash   equivalents  are   short-term,   highly  liquid   investments   with
insignificant  interest  rate risk and  original  maturities  of three months or
less.  Restricted and designated cash and short-term  investments  totaling $4.6
million at June 30, 2006 and $4.7  million at December  31, 2005 are included in
other assets.  The restricted funds represent those required for  self-insurance
purposes and designated  funds that are earmarked for a specific purpose not for
general business use.

Note 5.  Short-term Investments

     The Company  investments  are  primarily in the form of tax free  municipal
bonds  with  interest  reset  provisions  or  short-term  municipal  bonds.  The
investments  typically have a put option of 28 or 35 days. At the reset date the
Company has the option to roll the investment over or sell. The Company receives
the par value of the investment on the reset date if sold. The cost approximates
fair value due to the nature of the  investment.  Therefore,  accumulated  other


                                       6


comprehensive  income (loss) has not been recognized as a separate  component of
stockholders'  equity.  Investment  income  received  is  generally  exempt from
federal income taxes.

Note 6.  Property, Equipment, and Depreciation

     Property and equipment are stated at cost,  while  maintenance  and repairs
are charged to operations as incurred.

     Effective July 1, 2005, gains from the trade of revenue equipment are being
recognized  in  operating  income in  compliance  with  Statement  of  Financial
Accounting   Standards   ("SFAS")   No.  153,   "Accounting   for   Non-monetary
Transactions".  Prior to July 1,  2005,  gains  from  the  trade-in  of  revenue
equipment were deferred and presented as a reduction of the depreciable basis of
new revenue equipment.  Operating income for the three and six months ended June
30,  2006  were   favorably   impacted  by  $8.7  million  and  $11.3   million,
respectively,  from  gains on the  trade-in  of  revenue  equipment,  net of the
associated  increase  in  depreciation   expense  as  a  result  of  the  higher
depreciable basis of traded revenue equipment acquired since July 1, 2005.

Note 7. Stock Split

     On April 20, 2006, the Board of Directors  approved a four-for-three  stock
split,  affected  in the form of a 33 percent  stock  dividend.  The stock split
occurred on May 15,  2006,  to  shareholders  of record as of May 5, 2006.  This
stock split increased the number of outstanding shares to 98.4 million from 73.8
million.  The number of common shares issued and  outstanding  and all per share
amounts have been adjusted to reflect the stock split for all periods presented.

Note 8.  Earnings Per Share:

     Earnings  per share are  based  upon the  weighted  average  common  shares
outstanding   during  each  period.   Heartland  Express  has  no  common  stock
equivalents;  therefore,  diluted earnings per share are equal to basic earnings
per share.

Note 9.  Share Based Compensation

     On March 7, 2002,  the  Company  president  transferred  181,500 of his own
shares  establishing  a restricted  stock plan on behalf of key  employees.  The
shares  vest  over a five  year  period  or  upon  death  or  disability  of the
recipient.  The  shares  were  valued  at the  March  7,  2002  market  value of
approximately $2.0 million.  The market value of $2.0 million is being amortized
over a five year period as compensation expense. Compensation expense of $94,228
and $83,378 for the three month periods ended June 30, 2006 and 2005 is recorded
in salaries,  wages, and benefits on the consolidated  statement of income.  For
the six months  ended June 30, 2006 and 2005,  compensation  expense of $188,454
and $178,486 is recorded in salaries,  wages,  and benefits on the  consolidated
statement  of  income.  As of June 30,  2006,  there was  $250,247  of  unearned
compensation  cost related to the restricted  stock  granted.  This cost will be
recognized  over the next eight months.  All unvested shares are included in the
Company's 98.4 million outstanding shares.

     A summary of the Company's non-vested restricted stock as of June 30, 2006,
and changes  during the six months ended June 30, 2006 is presented in the table
below:

     The fair value of the shares  vested was  $563,607 and $535,787 for the six
months ended June 30, 2006 and 2005, respectively.

     In December 2004, the FASB issued SFAS No. 123(R), "Share-Based Payment," a
revision of SFAS No. 123, which addresses the accounting for share-based payment
transactions.  SFAS No.  123(R)  eliminates  the ability to account for employee
share-based compensation  transactions using APB Opinion No. 25, "Accounting for
Stock  Issued  to  Employees,"   and  generally   requires   instead  that  such
transactions be accounted and recognized in the consolidated statement of income
based on their fair value.  SFAS No. 123(R) also  requires  entities to estimate
the number of  forfeitures  expected to occur and record  expense based upon the
number of awards  expected to vest. The Company  implemented  SFAS No. 123(R) on
January  1,  2006.  The  unamortized   portion  of  unearned   compensation  was
reclassified  to retained  earnings upon  implementation.  The  amortization  of
unearned  compensation is being recorded as additional paid-in capital effective
January  1, 2006.  The  implementation  of SFAS No.  123(R) had no effect on the
Company's  results of  operations  for the three and six  months  ended June 30,
2006.

Note 10. Commitments and Contingencies

     The Company is party to ordinary,  routine  litigation  and  administrative
proceedings  incidental  to its  business.  In the  opinion of  management,  the
Company's  potential  exposure  under  pending legal  proceedings  is adequately
provided for in the accompanying consolidated financial statements.

     The  Company  had  commitments  at June 30,  2006 to  acquire  new  revenue
equipment  for  approximately  $66.7  million  in 2006.  These  commitments  are
expected to be financed from existing cash and  short-term  investment  balances
and cash flows from operations.

     The Company announced on June 9, 2006 that our Board of Directors  declared
a regular quarterly dividend of $.02 per common share,  payable on July 3, 2006,
to stockholders of record on June 22, 2006.

     The Company  announced on September 22, 2005 the planned  construction of a
new corporate  headquarters and an adjacent shop facility.  These new facilities
will be  funded  with the  proceeds  from the sale of the real  estate  and from
existing cash and short-term investment balances and cash flows from operations.
Construction is expected to be completed in the second quarter of 2007.

Note 11. Related Party Transactions

     The Company  leases two office  buildings  and a storage  building from its
president  under a lease that  provides for monthly  rentals of $27,618 plus the
payment of all property taxes, insurance and maintenance.  The lease was renewed
for a five year term on June 1, 2005, increasing the monthly rental from $24,969
to $27,618. In the opinion of management, the rates paid are comparable to those
that could be negotiated with a third party.

     Rent expense paid to the Company's  president  totaled  $82,854 and $74,906
for the three  months ended June 30, 2006 and 2005,  respectively.  Rent expense
paid to the Company  president  totaled $165,708 and $152,463 for the six months
ended June 30, 2006 and 2005,  respectively.  In 2005, the Company announced the
construction of a new corporate  headquarters  which is expected to be ready for
occupancy  in 2007.  The lease will be canceled  upon the  occupancy  of the new
corporate headquarters and shop facility.

     During the first quarter of 2006, the Company  purchased 16.7 acres of land
in North Liberty from the Company's president for $1,250,000. The purchase price
was based on the fair  market  value that could be  obtained  from an  unrelated
third party on an arm's length basis.  The transaction was approved by the Board
of Directors.

Note 12. Accounting Pronouncements

     In June 2006, the FASB issued FASB  Interpretation  No. 48 "Accounting  for
Uncertainty in Income Taxes (an interpretation of FASB Statement No. 109)" which
is effective  for fiscal years  beginning  after  December 15, 2006 with earlier
adoption  encouraged.  This  interpretation was issued to clarify the accounting
for  uncertainty  in income taxes  recognized  in the  financial  statements  by
prescribing a recognition  threshold and measurement attribute for the financial
statement  recognition and measurement of a tax position taken or expected to be
taken in a tax return. We are currently  evaluating the potential impact of this
interpretation.

Overview

     Heartland Express,  Inc. is a short- to medium-haul  truckload carrier. The
Company  transports freight for major shippers and generally earns revenue based
on the number of miles per load delivered. The Company provides regional dry van
truckload  services  from eight  regional  operating  centers plus its corporate
headquarters. The Company's eight regional operating centers accounted for 62.9%
of the second  quarter  2006  operating  revenues.  The Company  expanded to the
Western  United  States in the  second  quarter  of 2005 with the  opening  of a
regional  operating center in Phoenix,  Arizona.  The Company takes pride in the
quality  of  the  service  that  it  provides  to its  customers.  The  keys  to
maintaining a high level of service are the availability of late-model equipment
and experienced drivers.

     Operating  efficiencies  and cost controls are achieved  through  equipment
utilization,  operating a fleet of late model equipment, maintaining an industry
leading driver to non-driver  employee  ratio,  and the effective  management of
fixed and variable  operating  costs.  At June 30, 2006,  the Company's  tractor
fleet had an average age of 1.4 years while the trailer fleet had an average age
of 2.8 years. The Company has grown  internally by providing  quality service to
targeted  customers  with a high  density of freight in the  Company's  regional
operating  areas.  In  addition to the  development  of its  regional  operating
centers,  the Company has made five  acquisitions  since 1987.  Future growth is

                                       9


dependent upon several  factors  including the level of economic  growth and the
related  customer  demand,  the  available  capacity in the  trucking  industry,
potential of  acquisition  opportunities,  and the  availability  of experienced
drivers.

     The Company  ended the second  quarter of 2006 with  operating  revenues of
$143.1  million,  including fuel  surcharges,  net income of $24.8 million,  and
earnings per share of $0.25 on average  outstanding shares of 98.4 million.  The
Company posted a 75.2%  operating ratio  (operating  expenses as a percentage of
operating  revenues) and a 17.3% net margin.  The Company ended the quarter with
cash,  cash  equivalents,  and  short-term  investments  of $321.3 million and a
debt-free  balance sheet. The Company had total assets of $629.6 million at June
30,  2006.  The  Company  achieved  a return  on assets of 14.4% and a return on
equity  of  19.2%,  both  improvements  over the  second  quarter  of 2005.  The
Company's  cash flow from  operations  for the first six months of $55.9 million
represented a 12.9% increase over the same period of 2005.

     The Company hires only experienced  drivers with safe driving  records.  In
order to attract and retain experienced drivers who understand the importance of
customer  service,  the Company  increased pay for all drivers in the past three
consecutive years including an increase in 2006.  Effective October 2, 2004, the
Company began paying all drivers an  incremental  amount for miles driven in the
upper Northeastern  United States. The Company has solidified its position as an
industry leader in driver compensation with these aforementioned  increases. The
driver pay increases in 2006 are for selected  regional  operations  including a
fleet-wide  incentive  to maintain a hazardous  materials  endorsement  on their
commercial driver's license.

     The Company has been  recognized as one of the Forbes  magazine's "200 Best
Small  Companies in America"  fourteen  times in the past nineteen years and for
the past four  consecutive  years  including  2005.  The  Company  has paid cash
dividends over the past twelve consecutive quarters. The Company became publicly
traded in November,  1986 and is traded on the NASDAQ  National Market under the
symbol HTLD.

     The  following is a discussion  of the results of operations of the quarter
and six month period ended June 30, 2006  compared with the same periods in 2005
and the changes in financial condition through the second quarter of 2006.

Three Months Ended June 30, 2006 and 2005

     Operating revenue increased $14.2 million (11.0%), to $143.1 million in the
second  quarter of 2006 from $128.9  million in the second  quarter of 2005. The
increase  in revenue  resulted  from the  Company's  expansion  of its fleet and
improved  freight  rates.  Operating  revenue for both  periods  was  positively
impacted  by fuel  surcharges  assessed to  customers.  Fuel  surcharge  revenue
increased $8.4 million to $21.4 million in the second quarter of 2006 from $13.0
million in the second quarter of 2005.

     Salaries,  wages,  and benefits  increased  $2.6 million  (6.0%),  to $46.0
million in the second  quarter of 2006 from $43.4 million in the second  quarter
of 2005.  These  increases  were the result of  increased  reliance  on employee
drivers due to a decrease in the number of independent  contractors  utilized by
the  Company  and a driver pay  increase.  During  the  second  quarter of 2006,
employee drivers  accounted for 93% and independent  contractors 7% of the total
fleet miles,  compared with 91% and 9%,  respectively,  in the second quarter of
2005.  The  Company  implemented  an increase in driver pay during the first and
second  quarters of 2006. All drivers  maintaining a valid  hazardous  materials
endorsement  on their  commercial  driver's  license  received  a $0.01 per mile
increase in January 2006. Additional increases were given to drivers in selected
regional  operations.  Workers'  compensation  expense  increased  $0.5  million
(79.8%) to $1.1 million in the quarter  ended June 30, 2006 from $0.6 million in
for the same  period in 2005 due to an  increase in  frequency  and  severity of
claims.  Health insurance expense increased $0.2 million (10.7%) to $1.9 million
in the second quarter of 2006 from $1.7 million in second quarter of 2005 due to
an increase  in  frequency  and  severity  of claims and  increased  reliance on
employee drivers.

     Rent and purchased  transportation  decreased $1.0 million (13.5%), to $6.8
million in the second quarter of 2006 from $7.8 million in the second quarter of
2005.  This  reflects  the  Company's   decreased   reliance  upon   independent
contractors. Rent and purchased transportation for both periods includes amounts
paid to independent  contractors under the Company's fuel stability program. The
Company increased the independent  contractor base mileage pay by $0.01 per mile
in the first  quarter  of 2006 for all  independent  contractors  maintaining  a
hazardous  materials  endorsement on their commercial  driver's license,  and an
additional $0.01 per mile on April 1, 2006.

     Fuel  increased $9.3 million  (32.6%),  to $37.8 million in 2006 from $28.5
million  in 2005.  The  increase  is the result of  increased  fuel  prices,  an
increased  reliance on  company-owned  tractors,  and a decrease in fuel economy
associated with the EPA-mandated clean air engines.  The Company's fuel cost per
company-owned tractor mile increased 29.4% in second quarter of 2006 compared to
2005.  Fuel cost per mile, net of fuel  surcharge,  increased 4.4% in the second
quarter of 2006  compared to 2005.  The Company's  second  quarter fuel cost per
gallon  increased  26.6% in 2006 compared to 2005. In the quarter ended June 30,
2006, tractors with the EPA-mandated clean air engine accounted for 79.4% of the
miles   generated  by  the   company-owned   fleet  compared  to  40.1%  of  the
company-owned  fleet  in  the  2005  period.  Fuel  economy  for  tractors  with
EPA-mandated clean air engines decreased 5.3%.

     Operations and maintenance  decreased $0.4 million (11.1%), to $3.4 million
in the second  quarter of 2006 from $3.8 million in the second  quarter of 2005.
This is primarily  attributed to the average age of the revenue equipment in our
fleet.  The average age of our tractor  fleet is 1.4 years while the average age
of the trailer fleet is 2.8 years,  both improvements over the second quarter of
2005.

     Insurance and claims increased $0.8 million (21.8%), to $4.8 million in the
second quarter of 2006 from $4.0 million in the second quarter of 2005 due to an
increase in the frequency and severity of claims.

                                       11


     Depreciation  increased $2.1 million  (23.5%),  to $11.2 million during the
second  quarter of 2006 from $9.1  million in the second  quarter of 2005.  This
increase is attributable to the growth of our company-owned  tractor and trailer
fleet,  an  increased  cost  of  new  tractors  primarily  associated  with  the
EPA-mandated  clean air  engines,  and the  implementation  of SFAS No. 153. New
tractors have a higher cost than the models being  replaced due to  EPA-mandated
clean air standards.  As of June 30, 2006, 84.7% of the Company's  tractor fleet
had the EPA clean air engine compared to 47.3% at June 30, 2005. For the quarter
ended June 30, 2006,  implementation  of SFAS No. 153 resulted in  approximately
$0.7 million of additional  depreciation as a result of higher depreciable basis
of revenue equipment  acquired through trade-ins.  In future periods,  we expect
depreciation  will  increase as we  continue to upgrade our fleet in  compliance
with EPA-mandated engine changes and due to the impact of SFAS No. 153.

     Other operating  expenses increased $0.2 million (3.8%), to $4.2 million in
the  second  quarter of 2006 from $4.0  million  in the second  quarter of 2005.
Other operating  expenses  consists of costs incurred for  advertising  expense,
freight handling,  highway tolls, driver recruiting expenses, and administrative
costs.

     Gain on the  disposal of property  and  equipment  increased  $9.6  million
(7983.4%),  to $9.7 million  during the second quarter of 2006 from $0.1 million
in the second  quarter  of 2005.  For 2006,  $9.4  million  represents  gains on
trade-ins of revenue equipment which are recognized  currently under of SFAS No.
153.  These gains were  previously  deferred as a reduction  of the  depreciable
basis of new revenue equipment.

     Interest  income  increased  $0.8 million  (41.7%),  to $2.9 million in the
second  quarter  of 2006  from $2.1  million  in the same  period  of 2005.  The
increase is the result of higher average balances of cash, cash equivalents, and
short-term investments and higher yields than 2005.

     The Company's  effective  tax rate was 35.5% in the second  quarter of 2006
and 2005.

     As a result of the  foregoing,  the Company's  operating  ratio  (operating
expenses as a  percentage  of  operating  revenue)  was 75.2%  during the second
quarter of 2006  compared  with 80.4%  during  the second  quarter of 2005.  Net
income  increased  $7.2  million  (40.5%),  to $24.8  million  during the second
quarter of 2006 from $17.6 million during the second quarter of 2005.

Six Months Ended June 30, 2006 and 2005

     Operating revenue increased $30.6 million (12.3%), to $278.1 million in the
six months  ended June 30,  2006 from  $247.5  million in the 2005  period.  The
increase  in revenue  resulted  from the  Company's  expansion  of its fleet and
improved  freight  rates.  Operating  revenue for both  periods  was  positively
impacted  by fuel  surcharges  assessed to  customers.  Fuel  surcharge  revenue
increased  $15.6  million to $38.7 million in the six months ended June 30, 2006
from $23.1 million in the compared 2005 period.

     Salaries,  wages,  and benefits  increased  $6.2 million  (7.3%),  to $92.4
million in the six months  ended  June 30,  2006 from $86.2  million in the 2005
period.  These  increases  were the result of  increased  reliance  on  employee
drivers due to a decrease in the number of independent  contractors  utilized by
the  Company  and a driver  pay  increase.  During the first six months of 2006,
employee drivers  accounted for 93% and independent  contractors 7% of the total
fleet  miles,  compared  with 91% and 9%,  respectively,  in the  compared  2005
period.  The Company  implemented an increase in driver pay during the first and
second  quarters of 2006. All drivers  maintaining a valid  hazardous  materials
endorsement  on their  commercial  driver's  license  received  a $0.01 per mile
increase in January 2006. Additional increases were given to drivers in selected
regional  operations.  Workers'  compensation  expense  increased  $0.3  million
(16.7%) to $2.2  million in the six months ended June 30, 2006 from $1.9 million
in for the same period in 2005 due to an increase in  frequency  and severity of
claims.  Health insurance expense increased $0.4 million (11.7%) to $4.2 million
in the six months  ended June 30,  2006 from $3.8  million in the same period of
2005 due to an  increase  in  frequency  and  severity  of claims and  increased
reliance on employee drivers.

                                       12


     Rent and purchased  transportation decreased $2.5 million (16.5%), to $13.0
million in the first six months of 2006 from $15.5  million in the compared 2005
period.   This  reflects  the  Company's  decreased  reliance  upon  independent
contractors. Rent and purchased transportation for both periods includes amounts
paid to independent  contractors under the Company's fuel stability program. The
Company increased the independent  contractor base mileage pay by $0.01 per mile
in the first  quarter  of 2006 for all  independent  contractors  maintaining  a
hazardous  materials  endorsement on their commercial  driver's license,  and an
additional $0.01 per mile for all independent contractors on April 1, 2006.

     Fuel increased $16.7 million  (30.9%),  to $70.8 million in first six month
of 2006 from $54.1  million in the  compared  2005  period.  The increase is the
result  of  increased  fuel  prices,  an  increased  reliance  on  company-owned
tractors,  and a decrease in fuel economy associated with the EPA-mandated clean
air engines.  The Company's fuel cost per  company-owned  tractor mile increased
25.8% in the first six months of 2006 compared to the 2005 period. Fuel cost per
mile, net of fuel  surcharge,  increased .4% when comparing the first six months
2006 to the 2005 period.  The Company's fuel cost per gallon  increased 24.0% in
2006 compared to 2005. In the six months ended June 30, 2006,  tractors with the
EPA-mandated  clean air engine accounted for 75.0% of the miles generated by the
company-owned  fleet  compared to 36.3% of the  company-owned  fleet in the 2005
period.  Fuel economy for tractors with EPA-mandated clean air engines decreased
5.0%.

     Operations and  maintenance  was $6.3 million for both the six months ended
June 30, 2006 and 2005.  This is primarily  attributed to the average age of the
revenue  equipment  in our fleet.  The average  age of our tractor  fleet is 1.4
years while the average age of the  trailer  fleet is 2.8 years.  This  compares
favorably with the average  tractor age at 1.6 years and the average trailer age
at 3.0 years reported at June 30, 2005.

         Insurance and claims increased $2.1 million (31.2%), to $8.9 million in
the six months ended June 30, 2006 from $6.8 million in the same period of 2005
due to an increase in the frequency and severity of claims.

     Depreciation  increased $4.0 million  (22.5%),  to $21.4 million during the
first six months of 2006 from $17.4  million in the compared  2005 period.  This
increase is attributable to the growth of our company-owned  tractor and trailer
fleet,  an  increased  cost  of  new  tractors  primarily  associated  with  the
EPA-mandated  clean air  engines,  and the  implementation  of SFAS No. 153. New
tractors have a higher cost than the models being  replaced due to  EPA-mandated
clean air standards.  As of June 30, 2006, 84.7% of the Company's  tractor fleet
had the EPA clean air engine  compared  to 47.3% at June 30,  2005.  For the six
months  ended  June  30,  2006,  implementation  of SFAS  No.  153  resulted  in
approximately  $1.1  million of  additional  depreciation  as a result of higher
depreciable basis of revenue  equipment  acquired through  trade-ins.  In future
periods,  we expect  depreciation  will  increase  as we continue to upgrade our
fleet in compliance  with  EPA-mandated  engine changes and due to the impact of
SFAS No. 153.

     Other operating  expenses  increased $0.2 million  (1.4%),  to $8.4 million
during the six months  ended June 30, 2006 from $8.2  million in the same period
of 2005.  Other  operating  expenses  consists of costs incurred for advertising
expense,  freight  handling,  highway tolls,  driver  recruiting  expenses,  and
administrative costs.

     Gain on the  disposal of property and  equipment  increased  $12.5  million
(4138.0%),  to $12.8 million during the six months ended June 30, 2006 from $0.3
million in the compared 2005 period. For 2006, $12.4 million represents gains on
trade-ins of revenue equipment which are recognized  currently under of SFAS No.
153.  These gains were  previously  deferred as a reduction  of the  depreciable
basis of new revenue equipment.

     Interest income increased $2.0 million (59.8%),  to $5.4 million in the six
months  ended June 30, 2006 from $3.4  million in the same  period of 2005.  The
increase is the result of higher average balances of cash, cash equivalents, and
short-term investments and higher yields than 2005.

                                       13


     The Company's  effective  tax rate was 35.5% in the second  quarter of 2006
and 2005.

     As a result of the  foregoing,  the Company's  operating  ratio  (operating
expenses as a percentage  of  operating  revenue) was 77.1% during the first six
months of 2006  compared  with 80.9% during the same period of 2005.  Net income
increased $11.8 million (36.0%), to $44.5 million during the six months ended
June 30 2006 from $32.7 million during the compared 2005 period.

Liquidity and Capital Resources

     The growth of the Company's business has required  significant  investments
in new revenue equipment.  Historically the Company has been debt-free,  funding
revenue equipment  purchases with cash flow provided by operations.  The Company
also obtains tractor capacity by utilizing independent contractors,  who provide
a  tractor  and  bear all  associated  operating  and  financing  expenses.  The
Company's  primary  source of liquidity  for the six months ended June 30, 2006,
was net cash provided by operating activities of $55.9 million compared to $49.5
million in the corresponding 2005 period.

     Capital   expenditures  for  property  and  equipment,   primarily  revenue
equipment  net of  trade-ins,  totaled $20.8 million for the first six months of
2006  compared  to $19.7  million  for the same  period  in  2005.  The  Company
anticipates  new  tractor  and  trailer  purchases,   net  of  trades,  totaling
approximately  $94.4 million in 2006. The Company will buy  additional  tractors
before year-end prior to phase two of the federally  mandated  engine  emissions
standards that will become effective in January of 2007.

     The Company paid cash dividends of $3.0 million during the first six months
of 2006 and 2005,  respectively.  The Company began paying cash dividends in the
third quarter of 2003. The Company declared a $2.0 million cash dividend in June
2006, payable on July 3, 2006.

     Management  believes the Company has adequate liquidity to meet its current
and  projected  needs.  The Company will  continue to have  significant  capital
requirements over the long term. Future capital  expenditures are expected to be
funded  by cash  flow  provided  by  operations  and from  existing  cash,  cash
equivalents,  and  short-term  investments.  The Company  ended the quarter with
$321.3 million in cash,  cash  equivalents,  and short-term  investments  and no
debt.  Based on the Company's  strong financial  position,  management  believes
outside financing could be obtained, if necessary, to fund capital expenditures.

Off-Balance Sheet Transactions

     The Company's  liquidity is not materially  affected by  off-balance  sheet
transactions.

Risk Factors

     You should  refer to Item 1A of our annual  report (Form 10-K) for the year
ended December 31, 2005,  under the caption "Risk Factors" for specific  details
on the  following  factors  that are not within the  control of the  Company and
could affect our financial results.
     o    Our business is subject to general  economic and business factors that
          are largely out of our control.
     o    Our growth may not continue at historic rates.
     o    Increased prices, reduced productivity, and restricted availability of
          new revenue equipment may adversely affect our earnings and cash flow.
     o    If fuel prices increase significantly, our results of operations could
          be adversely affected.
     o    Difficulty  in  driver  and  independent  contractor  recruitment  and
          retention may have a materially adverse effect on our business.
     o    We operate in a highly  regulated  industry,  and  increased  costs of
          compliance  with, or liability for violation of, existing  regulations
          could have a materially adverse effect on our business.
     o    Our  operations  are  subject  to  various   environmental   laws  and
          regulations, the violations of which could result in substantial fines
          or penalties.


                                       14


     o    We may not make acquisitions in the future, or if we do, we may not be
          successful in integrating the acquired company,  either of which could
          have a materially adverse effect on our business.
     o    If we are unable to retain our key  employees  or find,  develop,  and
          retain service center managers, our business, financial condition, and
          results of operations could be adversely affected.
     o    We are highly dependent on a few major  customers,  the loss of one or
          more of which could have a materially adverse effect on our business.
     o    Seasonality   and  the  impact  of  weather   affect  our   operations
          profitability.
     o    Ongoing insurance and claims expenses could  significantly  reduce our
          earnings.
     o    We are dependent on computer and communications systems, and a systems
          failure could cause a significant disruption to our business.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

     The Company purchases only high quality, liquid investments.  Primarily all
investments as of June 30, 2006 have an original maturity or interest reset date
of twelve months or less. Due to the short term nature of the  investments,  the
Company is exposed to minimal  market risk related to its cash  equivalents  and
investments.

     The Company had no debt outstanding as of June 30, 2006 and therefore,  had
no market risk related to debt.

     As of June 30, 2006,  the Company did not have any long-term  fuel purchase
contracts, and had not entered into any other hedging arrangements, that protect
against fuel price  increases.  Volatile  fuel prices will continue to impact us
significantly.  A  significant  increase in fuel costs,  or a shortage of diesel
fuel, could materially and adversely affect our results of operations.

Item 4. Controls and Procedures

     As of the end of the period covered by this report, the Company carried out
an evaluation, under the supervision and with the participation of the Company's
management,  including the Company's Chief Executive Officer and Chief Financial
Officer,  of the  effectiveness  of the design and  operations  of the Company's
disclosure  controls  and  procedures,  and as  defined  in  Exchange  Act  Rule
15d-15(e). Based upon that evaluation, the Company's Chief Executive Officer and
Chief Financial  Officer  concluded that the Company's  disclosure  controls and
procedures are effective in enabling the Company to record,  process,  summarize
and report  information  required to be included in the  Company's  periodic SEC
filings  within  the  required  time  period.  There have been no changes in the
Company's  internal  controls over financial  reporting that occurred during the
Company's  most  recent  fiscal  quarter  that has  materially  affected,  or is
reasonably  likely to materially  affect,  the Company's  internal  control over
financial reporting.
