SOUTH JORDAN, UTAH, November 8, 2005 (NYSE: HW) - HEADWATERS INCORPORATED today
announced results for its fourth quarter and fiscal year ended September 30,
2005. Highlights for the quarter include:

         o Repayment of $50 million of higher interest rate second lien debt
         o Executed (HC)3TM license for Canadian tar sands upgrader
         o Announced intention to build H2O2 demonstration plant

Highlights for Fiscal 2005 include:

         o Generated fully diluted earnings per share growth in excess of 48%
         o Improved pro forma debt-to-EBITDA ratio from 4.16 to 2.36
         o Generated $151 million of positive cash flow from operations
         o Reduced Section 29 continuing revenue to less than 28% of total
           revenue
         o Reached $120 million settlement, plus ongoing revenue from positive
           resolution of AJG litigation

Total revenue for the quarter ended September 2005 was $315.1 million, up 59%
from $198.6 million reported for the September 2004 quarter. Operating income
increased 76%, to $70.2 million in the September 2005 quarter compared to $39.9
million in the prior year quarter. Net income for the September 2005 quarter was
$44.9 million or $0.95 of earnings per diluted share, using 48.7 million



weighted-average shares outstanding. Net income for the September 2004 quarter
was $19.5 million or $0.51 of earnings per diluted share, using 40.3 million
weighted-average shares outstanding.

Total revenue for the year ended September 30, 2005 was $1.065 billion, up 92%
from $554 million reported for the year ended September 30, 2004. Operating
income increased 85%, to $236.9 million for the year ended September 30, 2005
(including $26.9 million of non-recurring operating income, as described in our
third quarter 2005 earnings release), versus $127.8 million for the year ended
September 30, 2004 (including $20.1 million in non-recurring operating income).
Net income for the year ended September 30, 2005 was $121.3 million or $2.79 of
earnings per diluted share (including $0.39 of non-recurring earnings per
share), compared to $64.3 million or $1.88 of earnings per diluted share for the
year ended September 30, 2004 (including $0.25 of non-recurring earnings per
share).

Headwaters Construction Materials Performance

Revenues from the Construction Materials segment during the quarter ended
September 2005, increased $65.4 million or 78%, to $149.5 million versus $84.1
million for the prior fiscal quarter. Gross margin percentage increased from
33.8% for the September 2004 quarter to 34.2% for the 2005 quarter. The
September 2005 quarter includes the operations of all of the entities acquired
in 2004. In comparison, the September 2004 quarter includes less than one
month's revenues from Tapco (the acquisition of Tapco occurred on September 8,
2004). For fiscal 2005, revenues increased $385.9 million, or 288%, from $134.0
million in fiscal 2004 to $519.9 million in fiscal 2005. On a pro forma basis,
for the fiscal year comparison, revenues increased $62.5 million, or 13.7% from
$457.4 million in fiscal 2004 on a pro forma basis to $519.9 million in fiscal
2005 on an actual basis.

The Construction Materials segment has a pronounced seasonality associated with
its business cycle and the acquisitions of Tapco and Eldorado have accentuated
this seasonality. This seasonality has a more significant impact on operating
income than on revenue due to the relationship between fixed and variable costs.

Headwaters Resources Performance

Revenues from Headwaters Resources or the coal combustion products ("CCPs")
segment during the quarter ended September 2005 increased $9.0 million or 13%,
from $66.8 million to $75.8 million versus the comparable 2004 quarter. Gross
margin percentage increased from 27% to 28% versus the comparable 2004 quarter.
For fiscal 2005, revenues increased $36.6 million or 17%, from $210.2 million in
fiscal 2004 to $246.8 million in fiscal 2005.

Sales of high-value coal combustion products for the September 2005 quarter
totaled approximately 2.20 million tons, compared to approximately 2.08 million
tons in the September 2004 quarter, resulting in a 6% increase in tons of
high-value coal combustion products sold.

Headwaters Energy Services Performance

Chemical reagent sales increased $14.4 million, or 42%, in the September 2005
quarter to $48.6 million, compared to $34.2 million in the September 2004
quarter. Headwaters Energy Services' recurring license fees for the September
2005 quarter increased $15.0 million or 112%, from $13.4 million in fiscal 2004
to $28.4 million in fiscal 2005. The increase in license fee revenue in the



September 2005 quarter resulted primarily from the settlement of the AJG
litigation earlier in the year. Due to high oil costs, gross margins on chemical
reagent sales in the September 2005 quarter were 27% compared to 33% in the
September 2004 quarter. Headwaters expects continued pressure on reagent margins
during the next fiscal year.

In December 2004, Headwaters increased its minority interest in a Section 29
facility in West Virginia from approximately 9% to 19%. Energy Services now
provides reagent to this 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 small alternative fuel
facilities that are wholly owned. The tax credits from all of these facilities
are the primary reason for the reduction in Headwaters' effective tax rate for
fiscal 2005 to approximately 26%.

In 2005, Headwaters does not believe that there will be any phase out of Section
29 based on high oil prices. It is too early to estimate the impact, if any, on
Headwaters of a possible 2006 phase out of Section 29. Headwaters believes that
if 2006 average oil prices are consistent with today's oil prices (November 7th
light sweet crude for December delivery settled at $59.47 per barrel), there
will be little or no phase out of Section 29. Nevertheless, the retroactive
application of the Section 29 phase out provisions creates an environment of
uncertainty and 2006 operational decisions will be made by facility owners later
this year based on available information. If today's oil prices do not increase
significantly in 2006, Headwaters believes that many facilities will continue to
operate. At today's oil prices, Headwaters intends to operate its two small
alternative fuel facilities.

Headwaters Technology Innovation Group and New Product Development

During the year, HTIG completed a number of major milestones in the
commercialization process of its technologies. Most importantly, multiple pilot
plant (HC3) tests were completed, providing the data necessary to move forward
with the commercial scale test announced this week. Headwaters believes (HC)3
could ultimately result in increased production of approximately 350,000 to
600,000 barrels per day of light distillates from heavy oil feedstock material.

Agreements for coal to liquid project analysis were signed in India, the
Philippines, and China. Further, non-binding memorandums of understanding for
development of coal-to-liquid projects were signed for two projects in the
United States.

Headwaters and its hydrogen peroxide development partner concluded that the
pilot plant tests conducted during 2005 were successful and arranged for the
construction of a demonstration facility. The operation of the demonstration
facility will provide the engineering data necessary to use the technology in
commercial scale plants. Headwaters anticipates multiple opportunities for the
implementation of its technology.

During the year, Headwaters successfully tested its reforming catalyst and
demonstrated that it produced results significantly superior to existing
reforming products. Use of Headwaters' reforming catalyst could not only produce
high grade gasoline more efficiently, but also create up to 20% more hydrogen
than is normally produced as a byproduct during the reforming reaction.



Growth Profile

The following table shows the actual and pro forma percentage growth in revenue,
operating income, net income, and fully diluted EPS for the fiscal year 2005.
The pro forma information assumes all of the acquisitions occurred on October 1,
2003.

                                     Actual               Pro forma

Revenue                                92%                   19%
Operating Income                       85%                   27%
Net Income                             89%                   66%
Diluted EPS                            48%                   26%
- ----------------------------- ---------------------- ---------------------

Seasonality

Since 2002, Headwaters' business has reflected increased seasonality factors
associated with its Construction Materials and CCP business segments. The
acquisitions completed during fiscal 2004 added to the seasonality of the
business. It has not been Headwaters' practice to provide quarterly estimates
and the Company does not intend to provide quarterly estimates going forward.
However, management believes it is important to provide some initial quarterly
guidance for fiscal 2006 to clarify the seasonality of Headwaters' business.
Accordingly, Headwaters' estimated quarterly revenue and earnings per share for
fiscal 2006, as a percent of the respective estimated totals for the fiscal 2006
year, are as follows:

                                        Revenue            Earnings Per Share
- --------------------------------- --------------------- ------------------------
December 31, 2005 quarter              22% - 24%                20% - 22%
March 31, 2006 quarter                 21% - 23%                18% - 20%
June 30, 2006 quarter                  26% - 28%                28% - 30%
September 30, 2006 quarter             27% - 29%                30% - 32%
- --------------------------------- --------------------- ------------------------

Capital Structure / Indebtedness

In addition to the early repayment of $197 million of its senior debt in March
2005 and $50 million of its second lien senior debt in May 2005, Headwaters
repaid the remaining $50 million of its second lien debt in September 2005. In
connection with this early payment, Headwaters recognized additional interest
expense totaling approximately $2.2 million, representing acceleration of
amortization of debt issuance costs and an early payment premium.



The components of Headwaters' debt structure as of September 30, 2005 are as
follows:


                                                         Amount
(in millions)                                          Outstanding      Interest Rate           Maturity

- ------------------------------------------------ ----------------- ------------------------ -----------------


In October 2005 Headwaters and its senior secured lenders amended the credit
agreement for Headwaters' senior first lien term loan. The amendment permits
Headwaters to participate in joint venture investments, subject to certain
conditions, and increases the amount of capital expenditures Headwaters may make
each year for the remaining term of the loan.

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 net
interest expense, income taxes, depreciation and amortization ("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.

sheet ratios using period end balances and the trailing twelve months ("TTM")
