         o 28% Increase in Revenue to $280.5 Million
         o 154% Increase in Net Income to $28.3 Million
         o 100% Increase in Diluted EPS to $0.60

         o Final $70 Million of Litigation Settlement Received in January

SOUTH JORDAN, UTAH, January 24, 2006 (NYSE: HW) - HEADWATERS INCORPORATED today
announced results for its quarter ended December 31, 2005. Total revenue for the
quarter ended December 31, 2005 was $280.5 million, up 28% from $218.4 million
reported for the December 2004 quarter. Operating income increased 42%, to $50.3
million in the December 2005 quarter compared to $35.3 million in the prior year
quarter. Net income for the December 2005 quarter was $28.3 million or $0.60 of
earnings per diluted share, using 48.6 million weighted-average shares
outstanding. Net income for the December 2004 quarter was $11.1 million or $0.30
of earnings per diluted share, using 40.6 million weighted-average shares
outstanding.

Headwaters Resources Performance

Revenues from Headwaters' coal combustion products ("CCPs") segment during the
quarter ended December 2005 increased $12.1 million or 23%, from $53.1 million
to $65.2 million versus the comparable December 2004 quarter. Gross margin
percentage increased from 23% to 25% versus the comparable 2004 quarter. The
increase in revenue and gross margin percentage resulted from a combination of
continued strong demand for CCPs, upward pricing trends in most concrete
markets, and increased project revenues. In addition, weather conditions in the
south central region of the United States were favorable.

Sales of high-value coal combustion products for the December 2005 quarter
totaled approximately 1.8 million tons, compared to approximately 1.5 million



tons in the December 2004 quarter, resulting in a 19% increase in tons of
high-value coal combustion products sold. High-value CCP sales for the calendar
year 2005 totaled 7.4 million tons, compared to 6.6 million tons in calendar
2004.

Headwaters Construction Materials Performance

Revenues from Headwaters' construction materials segment during the quarter
ended December 2005 increased $16.3 million or 14%, to $130.0 million versus
$113.7 million for the prior year quarter. Gross margin percentage decreased
from 33% for the December 2004 quarter to 31% for the 2005 quarter. Revenue
increases occurred across all major product lines. The primary reason for the
decline in gross margin percentage related to higher raw material costs and
additional expense associated with the ramp-up and restructuring of operations
at certain manufacturing facilities.

In light of a softening in new residential construction, Headwaters'
construction materials segment is benefiting from its product and geographic
diversification. For example, we are beginning to experience sales directly
related to the hurricane reconstruction effort in the Southeast. Our product
diversification allows us to market multiple products in the hurricane affected
region. Furthermore, we are also benefiting from strength in commercial,
infrastructure, and exterior remodeling markets.

Headwaters Energy Services Performance

Chemical reagent sales increased $7.7 million, or 21%, in the December 2005
quarter to $44.5 million, compared to $36.8 million in the December 2004
quarter. Headwaters Energy Services' license fees for the December 2005 quarter
increased $13.5 million or 92%, from $14.6 million in December 2004 to $28.1
million in December 2005. The increase in license fee revenue in the December
2005 quarter resulted primarily from increased production and the settlement of
the AJG litigation. Due to raw material cost increases, gross margins on
chemical reagent sales in the December 2005 quarter were 25% compared to 33% in
the December 2004 quarter. Headwaters expects reagent margins to stabilize in
the 25% range during 2006, depending upon crude oil prices and the availability
of raw material feedstocks.

Tax credits from Headwaters' three investments in Section 29 facilities were the
primary reason for the reduction in Headwaters' effective tax rate for the
December 2005 quarter to 26% from 37% in the December 2004 quarter. Headwaters
realized $11.5 million in revenues from the sale of synfuel produced at its
wholly owned Section 29 facilities and recorded $13.3 million in costs of
synfuel sales.

Tax credits claimed by alternative fuel facility owners may begin to be phased
out or eliminated prior to their scheduled expiration on December 31, 2007 if
the "reference price" of oil enters into or exceeds an established average
annual range of oil prices, adjusted annually for inflation. The reference price
of oil is determined annually and usually released in the first week of April
for the previous year, resulting in a retroactive application of the phase out
process. We will not officially know the reference price for 2006 until the
spring of 2007. Unfortunately, this retroactive application of the reference
price creates an uncertain environment, forcing owners to base current
production decisions on predictions of future oil prices.



We have recently become aware of three facilities owned by a licensee of
Headwaters that have curtailed production due to the uncertain oil price
environment. The decision to curtail production may be temporary or long term
depending upon oil price movement. In addition, there may be a legislative
opportunity to change the phase out to a reference price that is applied
prospectively rather than retroactively. Such a change would eliminate the
uncertainty that currently exists and allow appropriate production decisions to
be made based on historical oil prices. If there is a legislative change that
eliminates the uncertainty, the owner of the three facilities that curtailed
production may reverse its decision.

Headwaters is unaware of any other facilities that have curtailed production.
Several other Headwaters licensees have established hedging positions related to
the price of oil, which may enable them to continue operating. However, high oil
prices create an uncertain environment that could result in further curtailment
of production. As a part of our March quarter earnings release, we expect to
provide an update of the status of our licensee operations and estimate the
financial impact that curtailment will have on Headwaters fiscal 2006 earnings.

Headwaters Technology Innovation Group and New Product Development

As recently announced, HTIG successfully completed its first commercial scale
(HC)3 test in early December 2005. The test results increased the conversion of
heavy oil to lighter distillates as high as 20% above previous limits,
consistent with expectations. The refinery is continuing to evaluate the results
of the test and is considering a license agreement with Headwaters' heavy oil
subsidiary to use (HC)3 technology and purchase catalyst material to enhance the
value of its heavy oil upgrading operations.

Headwater/Degussa direct synthesis hydrogen peroxide demonstration plant is
under construction. Headwaters is reviewing opportunities to accelerate the
commercialization of its hydrogen peroxide technology. Further, we have
completed a series of benchmark reforming catalyst tests providing additional
confirmation of the improvements to the reforming process provided by
Headwaters' technology.

Capital Structure / Indebtedness

The components of Headwaters' debt structure as of December 31, 2005 are as
follows:

                                          Amount
(in millions)                          Outstanding  Interest Rate    Maturity
- --------------------------------------------------------------------------------
Senior secured first lien term loan      $439.3    LIBOR + 2.25%    April 2011
- --------------------------------------------------------------------------------
Industrial Revenue Bond and other          $7.9    4.8% to 7.0%     Currently
                                                                     Callable
- --------------------------------------------------------------------------------
Senior revolving credit facility          $30.0   Prime + 0.75%   September 2009
($60.0 million available less out-
standing letters of credit of
approximately $8.2
- --------------------------------------------------------------------------------
Senior subordinated convertible debt     $172.5       2.875%        June 2011
- --------------------------------------------------------------------------------
      Total                              $649.7
- --------------------------------------------------------------------------------

In January 2006, Headwaters received the final $70.0 million payment due from
the litigation settlement reached with AJG in 2005. Using these proceeds,
Headwaters repaid all of the $30.0 million outstanding under the revolving



credit facility and also repaid an additional $24.0 million of the first lien
term loan, effectively pre-paying all scheduled principal payments on the
term-debt until November 2007.

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.

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

                                 Pro forma     Actual      Actual     Pro forma
                                  9/30/04      9/30/05    12/31/05     12/31/05
- --------------------------------------------------------------------------------
TTM EBITDA (in millions)           $233.8      $277.6      $292.8       $292.8
- --------------------------------------------------------------------------------
Total Indebtedness to TTM EBITDA    4.16        2.36        2.22         2.03
- --------------------------------------------------------------------------------
Current Ratio                       1.24        1.49        1.58         1.67

Total Debt to Equity                3.16        0.95        0.90         0.83
- --------------------------------------------------------------------------------

         The pro forma September 2004 calculations assume all of the 2004
acquisitions occurred on October 1, 2003. The pro forma December 2005
calculations assume the $54.0 million of debt repayments made in January 2006
were made on December 31, 2005. Pro forma EBITDA for the trailing twelve months
ended September 30, 2004 of $233.8 million is derived as follows (in millions):
Net income of $72.9 plus net interest expense of $63.1, income taxes of $45.6,
and depreciation and amortization of $52.2. Actual EBITDA for the trailing
twelve months ended September 30, 2005 of $277.6 million is derived as follows
(in millions): Net income of $121.3 plus net interest expense of $57.4, income
taxes of $42.5, and depreciation and amortization of $56.4. Actual EBITDA for
the trailing twelve months ended December 31, 2005 of $292.8 million is derived
as follows (in millions): Net income of $138.4 plus net interest expense of
$50.6, income taxes of $46.0, and depreciation and amortization of $57.8. Also,
see "Current Ratio" calculations in financial tables that follow.

Commentary and Outlook

Scott K. Sorensen, Headwaters' Chief Financial Officer, stated, "Our financial
results in our first fiscal quarter continue the track record of consistent
earnings and revenue growth. While uncertainty exists in our synfuels business,
we believe our understanding of the potential financial impact of phase-out due
to high oil prices will improve prior to the end of our fiscal second quarter.
We expect to update our consolidated Headwaters view on guidance estimates for
the full fiscal year in our fiscal second quarter earnings release." Mr.
Sorensen added, "Our operating businesses are performing well and we are very
optimistic about Headwaters' opportunities for further growth and investment."



"We have been able to introduce several new building products during the quarter
that were well received at the national building products show in Orlando this
January. We are excited about our slate roofing and architectural brick
products. Over the next year we plan to expand the distribution of these
products into our network of wholesale distributors," said Kirk A. Benson,
Chairman and Chief Executive Officer. "Our coal cleaning operation is on track,
and with our first facility coming on line the first week of January, we
anticipate receiving revenue from this new business opportunity in the March
quarter."
