                                     -more-

Net income after consideration of the above items                  $   36,458
                                                                   ==========

Earnings per share after consideration of the above items          $     0.78
                                                                   ==========

Contract litigation settlement and related items - As previously announced,
Headwaters reached a successful settlement agreement with AJG Financial
Services, Inc. ("AJG") with regard to litigation regarding a synfuel licensing
agreement. Among other terms, the litigation was settled for a payment of $50
million received in May 2005 plus a payment of $70 million to be received on or
before January 15, 2006. The $70 million relates to a contract modification
covering calendar years 2005 through 2007 and Headwaters is recognizing this as
revenue, net of amounts owed to a third party, over that period. Headwaters also
was required to pay a portion of the $50 million to that same third party. The
net amounts recorded in the June 2005 quarter which related to periods prior to
April 1, 2005, reduced by related performance-based bonus obligations, totaled
approximately $44.2 million.

SFAS No. 123R implementation - Headwaters elected to early adopt SFAS No. 123R
effective as of October 1, 2004. Under SFAS No. 123R, compensation expense
related to share-based payments to employees is reflected as an expense in the
statement of operations. During the quarter ended June 30, 2005, Headwaters
expensed a total of approximately $27.2 million related to share-based payments,
comprised of options, stock appreciation rights and stock issuances under
Headwaters' employee stock purchase plan. Of the $27.2 million expensed in the
June 2005 quarter, $25.5 million related to the grant of stock appreciation
rights and the acceleration of vesting of certain stock options granted in
periods prior to April 1, 2005. The remaining $1.7 million relates to the
ongoing vesting of awards granted in both the June 2005 quarter and in previous
periods.

In addition, because Headwaters adopted SFAS No. 123R effective as of October 1,
2004, the Statement of Income for the nine months ended June 30, 2005 includes

                                     -more-


the restatement of the six months ended March 31, 2005 to reflect the costs of
share-based payments for that period as an expense. The restatement of the six
months ended March 31, 2005 reduced net income for the nine months ended June
30, 2005 by approximately $3.9 million.

Net license fee revenue related to prior periods - In connection with the
settlement of the AJG litigation, Headwaters also recognized as revenue
approximately $8.2 million of revenue from a licensee with an indirect interest
in that litigation, all of which related to periods prior to January 1, 2005.

Headwaters Construction Materials Performance

Revenues from the construction materials segment were $147.6 million during the
June 2005 quarter, with a gross margin percentage of 34% (gross margin
percentage is calculated as follows: subtract cost of revenues from revenues,
and divide the number so derived by revenues), compared to revenue of $26.8
million and a gross margin of 25% for the June 2004 quarter. The June 2005
quarter includes the operations of Tapco, Eldorado Stone, and Southwest Concrete
Products ("SCP"). In comparison, the June 2004 quarter reflected only one
month's revenues from Eldorado with respect to acquired entities. The
Construction Materials segment has a pronounced seasonality. The seasonality has
a more significant impact on net income than on revenue due to the relationship
between fixed and variable costs.

Headwaters Resources Performance

During the June 2005 quarter, revenues from Headwaters Resources or the coal
combustion products ("CCPs") segment were $69.5 million with a gross margin of
26% compared to revenue of $58.7 million and a gross margin of 25% for the June
2004 quarter. Both quarters include the operations of VFL Technologies which has
historically had lower margins than Headwaters Resources' base business. Sales
of high-value coal combustion products for the June 2005 quarter totaled
approximately 2.0 million tons, compared to approximately 1.8 million tons in
the June 2004 quarter, resulting in an 11% increase in tons of high-value coal
combustion products sold.

Headwaters Energy Services Performance

Chemical reagent sales increased 27% in the June 2005 quarter to $45.0 million,
compared to $35.3 million in the June 2004 quarter. Headwaters Energy Services'
license fees for the June 2005 quarter were $41.7 million (including $13 million
of non-recurring license fee revenue) compared to $13.4 million in the June 2004
quarter. The increase in license fee revenue in the June 2005 quarter resulted
primarily from the settlement of the AJG litigation. Due to high oil costs,
gross margins on chemical reagent sales were 29% compared to 33% in the June
2004 quarter. Headwaters expects continued pressure on margins throughout the
remainder of the calendar year.

During the June 2005 quarter, Energy Services' licensees sold 12.1 million tons
of solid alternative fuel. This compares to 12.4 million tons sold in the June
2004 quarter and 11.7 million tons sold in the March 2005 quarter. Energy
Services sold 33.3 million pounds of chemical reagent in the June 2005 quarter,
compared to 26.0 million pounds in the June 2004 quarter and 29.6 million pounds

                                     -more-


in the March 2005 quarter. The 12.1 million tons of fuel sold was produced at 24
of the 28 licensed facilities, resulting in average quarterly production of
503,000 tons per facility. The highest number of tons produced from any one
facility in the quarter was 878,000, and the lowest was 80,000. Energy Services
sold chemical reagent to a total of 35 facilities, compared to a total of 30
facilities in the June 2004 quarter. Of the 35 facilities, 19 were licensee
facilities and 16 were facilities where solely chemical reagent was sold.

During December 2004, Headwaters increased its minority interest in a Section 29
facility currently operating in West Virginia from approximately 9% to 19%.
Energy Services has been providing reagent to the facility and is currently
recognizing its portion of the facility's operating expenses, included in "Other
Income (Expense)", and the tax credits generated by the facility, included in
"Income Tax Provision." In addition, in April 2005, Headwaters began operating
two other small alternative fuel facilities that it owns. The tax credits from
all of these facilities are the primary reason for the reduction in Headwaters'
estimated effective tax rate for fiscal 2005 to approximately 30%. Generally
accepted accounting principles require tax credits to be recognized
proportionately throughout the year in relation to a company's projected annual
taxable income. This results in fewer tax credits being recognized in
Headwaters' December and March quarters than are actually being generated at the
Section 29 facilities. The credits that are not recognized in Headwaters' lowest
income producing quarters, December and March, are recognized in the June and
September quarters.

Capital Structure / Indebtedness

In addition to the early repayment of $197 million of its senior debt in March
2005, Headwaters repaid $50 million of its second lien senior debt in May, using
proceeds from the AJG settlement. In connection with this early payment,
Headwaters recognized additional interest expense totaling approximately $2.8
million representing acceleration of amortization of debt issue costs and an
early payment premium.

The major components of Headwaters' long-term senior debt structure as of June
30, 2005 are as follows:

(in millions)                            Amount    Interest Rate     Maturity
- --------------------------------------- --------- --------------- --------------
Senior secured first lien term loan      $442.7    LIBOR + 2.25%    April 2011
- --------------------------------------- --------- --------------- --------------
Second lien term loan                    $ 50.0     LIBOR + 5.5%  September 2012
- --------------------------------------- --------- --------------- --------------
Senior subordinated convertible debt     $172.5        2.875%       June 2011
- --------------------------------------- --------- --------------- --------------

To supplement our condensed consolidated financial statements presented in
accordance with generally accepted accounting principles ("GAAP"), we use a
non-GAAP measure called EBITDA. EBITDA is net income adjusted by adding
depreciation, amortization, net interest expense and income taxes ("EBITDA").
Management uses EBITDA internally to measure the amount of cash generated by
Headwaters and to make decisions about the amount of capital expenditures
Headwaters will make and where to allocate capital. EBITDA is also provided to
enhance the user's overall understanding of our current financial performance,
our ability to service our debt, our compliance with current debt covenants and
our ability to fund future growth. Therefore, we believe that EBITDA provides
useful information to our investors regarding our performance and overall
results of operations. Our EBITDA measure presented here may not be comparable
to similarly titled measures presented by other companies.

The following table highlights certain debt coverage and balance sheet ratios
using period end balances and the trailing twelve months ("TTM") EBITDA:

- --------------------------------------- --------- ------------ ------------
Total Indebtedness to EBITDA(a)           1.53       4.16          2.58
- --------------------------------------- --------- ------------ ------------
EBITDA to Required Interest Payments(a)   7.73       4.60          7.23
- --------------------------------------- --------- ------------ ------------
Current Ratio(a)                          1.19       1.24          1.62
- --------------------------------------- --------- ------------ ------------
Total Debt to Equity                      0.96       3.16          1.07
- --------------------------------------- --------- ------------ ------------

         (a) See "Current Ratio" calculations in financial tables that follow.
The pro forma calculations of Total Indebtedness to EBITDA assumes all of the
2004 acquisitions occurred on October 1, 2003. Pro forma EBITDA for the trailing
twelve months ended June 30, 2005 of $260.9 million is derived as follows (in
millions of dollars): Net income of $99.5 plus net interest expense of $59.7,
income taxes of $46.9, and depreciation and amortization of $54.8. Pro forma
EBITDA for the trailing twelve months ended September 30, 2004 of $233.8 million
is derived as follows (in millions of dollars): Net income of $72.9 plus net
interest expense of $63.1, income taxes of $45.6, and depreciation and
amortization of $52.2.

Commentary and Outlook

Steven G. Stewart, Headwaters' Chief Financial Officer, stated, "Given the AJG
settlement and the strong financial performance of our operating companies, we
are pleased to update our earnings forecast for the current fiscal year. We are
raising our forecast of EPS from $2.00 to $2.10 to a new forecast of $2.20 to
$2.30 of diluted EPS, exclusive of non-recurring items totaling $0.39 per share.
These non-recurring items will increase our reported diluted earnings per share
to a range of $2.59 to $2.69 for our fiscal 2005 year ending September 30,
2005."

"In addition to strong operating performance during the quarter, we made
significant progress on the advancement of several of our energy technologies,"
said Kirk A. Benson, Chief Executive Officer. "We are positioned to conduct the
commercial scale test of our HC3 heavy oil technology later this summer and
expect to generate revenues in the calendar year."
