NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2007
(Unaudited)

1.Nature of Operations and Basis of Presentation

Description of Business and Organization — Headwaters Incorporated (“Headwaters”) is incorporated in Delaware and is a diversified company providing products, technologies and services in two industries: building materials, which includes construction materials and coal combustion products (“CCPs”), and alternative energy. Headwaters uses technology to differentiate itself from competitors and to create value in its businesses.

In the building materials sector, Headwaters designs, manufactures, and sells architectural stone and resin-based exterior siding accessories (such as shutters, mounting blocks, and vents) and other products. Headwaters is also a nationwide leader in the management and marketing of CCPs, including fly ash used as a substitute for portland cement. Headwaters believes it is uniquely positioned to manufacture an array of building materials that use fly ash, such as block, stucco, and mortar and believes that it has a leading market position in its principal building materials businesses. Revenue from Headwaters’ construction materials and CCPs businesses are diversified geographically and also by market, including the new construction, remodeling and home improvement markets.

In the alternative energy sector, Headwaters is focused on reducing waste and increasing the value of energy feedstocks, primarily in the areas of low-value coal and oil. In coal, Headwaters owns and operates two coal reclamation facilities that remove rock, dirt, and other impurities from waste coal, resulting in higher-value, marketable coal. Headwaters also licenses technology and sells reagents to the coal-based solid alternative fuel industry. In oil, Headwaters believes that its heavy oil upgrading technology represents a substantial improvement over current refining technologies. Headwaters’ heavy oil upgrading process uses a liquid catalyst precursor to generate a highly active molecular catalyst to convert residual oil feedstocks into higher-value distillates that can be refined into gasoline, diesel and other products. In addition, Headwaters operates an ethanol plant and is proceeding with the commercialization of several catalyst technologies.

Basis of Presentation — Headwaters’ fiscal year ends on September 30 and unless otherwise noted, references to 2006 refer to Headwaters’ fiscal quarter and/or six-month period ended March 31, 2006 and references to 2007 refer to Headwaters’ fiscal quarter and/or six-month period ended March 31, 2007. Other references to years refer to Headwaters’ fiscal years, unless otherwise noted. The consolidated financial statements include the accounts of Headwaters, all of its subsidiaries and other entities in which Headwaters has a controlling interest. All significant intercompany transactions and accounts are eliminated in consolidation. Due to the seasonality of the operations of the building materials businesses and other factors, Headwaters’ consolidated results of operations for 2007 are not indicative of the results to be expected for the full fiscal 2007 year.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, and consist of normal recurring adjustments. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in Headwaters’ Annual Report on Form 10-K for the year ended September 30, 2006 (“Form 10-K”) and in Headwaters’ Quarterly Report on Form 10-Q for the quarter ended December 31, 2006.

Recent Accounting Pronouncements — In July 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109 (“FIN 48”). This Interpretation prescribes a consistent recognition threshold and measurement standard, as well as clear criteria for subsequently recognizing, derecognizing and measuring tax positions, for financial reporting purposes. FIN 48 also requires expanded disclosures with respect to the uncertainty in income taxes. FIN 48 is effective for Headwaters’ fiscal 2008 year beginning on October 1, 2007. Management is currently evaluating the impact of FIN 48. The effect of adopting FIN 48, if material, will be a transition adjustment to beginning retained earnings in the year of adoption.

7

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”) which addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under generally accepted accounting principles. Headwaters must adopt SFAS No. 157 no later than in its fiscal year ending September 30, 2009. Headwaters uses fair value measurements to determine the reported amounts of assets acquired and liabilities assumed in purchase transactions, in testing for potential goodwill impairment, for disclosure of the fair value of financial instruments, and elsewhere. It is therefore possible that the implementation of SFAS No. 157 could have a material effect on the reported amounts or disclosures in Headwaters’ consolidated financial statements in future periods.

Headwaters has reviewed all other recently issued accounting standards which have not yet been adopted in order to determine their potential effect, if any, on the results of operations or financial position of Headwaters. Based on that review, Headwaters does not currently believe that any of these other recent accounting pronouncements will have a significant effect on its current or future financial position, results of operations, cash flows or disclosures.

Reclassifications — Certain prior period amounts have been reclassified to conform to the current period’s presentation. The reclassifications had no effect on net income or total assets.

2.Segment Reporting

Headwaters currently operates in two industries and reports three business segments, the construction materials and CCPs segments in the building materials industry, and the alternative energy segment in the energy industry. Revenues for the construction materials segment consist of product sales to wholesale and retail distributors, contractors and other users of building products. CCP revenues consist primarily of fly ash and other product sales with a small amount of service revenue. Revenue for the alternative energy segment consists primarily of sales of chemical reagents and license fees.

The following segment information has been prepared in accordance with SFAS No. 131, “Disclosure about Segments of an Enterprise and Related Information.” Segment performance is evaluated primarily on revenue and operating income, although other factors are also used, such as income tax credits generated by activities of the alternative energy segment. Intersegment sales are immaterial.

Segment costs and expenses considered in deriving segment operating income include cost of revenue, amortization, research and development, and segment-specific selling, general and administrative expenses. Amounts included in the “Corporate” column represent expenses not specifically attributable to any segment and include administrative departmental costs and general corporate overhead. Segment assets reflect those specifically attributable to individual segments and primarily include accounts receivable, inventories, property, plant and equipment, intangible assets and goodwill. Cash and cash equivalents and other assets are included in the “Corporate” column.

3.Securities and Stock-Based Compensation

SEC Registration Statements — In January 2007, Headwaters filed a registration statement on Form S-4 with the SEC to register the exchange of $172.5 million new 2.875% convertible senior subordinated notes due 2016 and the common stock which could be issued upon conversion of the notes, all in connection with a potential exchange offer for Headwaters’ existing 2.875% convertible senior subordinated notes due 2016 (see Note 6). The registration statement

was reviewed by the SEC and was declared effective in April 2007. Also described in Note 6, in January 2007, Headwaters issued a new series of $160.0 million 2.50% convertible senior subordinated notes due 2014. Headwaters filed a registration statement with the SEC to register the resales of these notes and the common stock which may be issued upon conversion of the notes, which registration statement became effective in April 2007.

Stock-Based Compensation — Total stock-based compensation expense, none of which involved the expenditure of cash, was approximately $1.8 million and $1.6 million for the three months ended March 31, 2006 and 2007, respectively, and $3.6 million and $3.4 million for the six months ended March 31, 2006 and 2007, respectively.

Senior Secured Credit Agreements — Headwaters’ senior secured credit facility currently consists of a first lien term loan in the amount of $262.5 million. The credit facility also provides for up to $60.0 million of borrowings under a revolving credit arrangement, with the ability to increase this amount to $100.0 million, subject to obtaining additional revolving loan commitments. The first lien term loan is senior in priority to all other debt and is secured by all assets of Headwaters. The terms of the credit facility, as currently amended, are described in more detail in the following paragraphs. Headwaters is in compliance with all debt covenants as of March 31, 2007.

The first lien term loan bears interest, at Headwaters’ option, at either i) the London Interbank Offered Rate (“LIBOR”) plus 2.0%, 2.25%, or 2.5%, depending on the credit ratings that have been most recently announced for the loans by Standard & Poor’s Ratings Services (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”); or ii) the “Base Rate” plus 1.0%, 1.25%, or 1.5%, again depending on the credit ratings announced by S&P and Moody’s. Base rate is defined as the higher of the rate announced by Morgan Stanley Senior Funding and the overnight rate charged by the Federal Reserve Bank of New York plus 0.5%. Headwaters’ current rate is LIBOR plus 2.0%. Headwaters can lock in new LIBOR rates for the first lien loan for one, two, three or six months. The weighted-average interest rate on the first lien debt was approximately 6.4% at March 31, 2007, after giving consideration to the effect of the interest rate hedge on $150.0 million of this debt, as described hereafter. Interest on the first lien term loan is generally payable on a quarterly basis.

In January 2007, Headwaters issued $160.0 million of new convertible senior subordinated notes due 2014. Headwaters used most of the net proceeds from these notes and available cash to repay $152.8 million of the first lien term loan. As a result of this early repayment, the remaining balance of the first lien term loan of $262.5 million is repayable as follows: $12.1 million in November 2010, and two payments of $125.2 million each in February 2011 and April 2011, the termination date. Due to the early repayment, Headwaters accelerated the amortization of related debt issue costs totaling approximately $2.0 million, which amount was charged to interest expense. There are mandatory prepayments of the first lien term loan in the event of certain asset sales and debt and equity issuances and from “excess cash flow,” as defined in the agreement. Optional prepayments of the first lien term loan are permitted without penalty or premium. Once repaid in full or in part, no further reborrowings can be made.

Borrowings under the revolving credit arrangement are generally subject to the terms of the first lien loan agreement and bear interest at either LIBOR plus 1.75% to 2.5% (depending on Headwaters’ “total leverage ratio,” as defined), or the Base Rate plus 0.75% to 1.5%. Borrowings and reborrowings of any available portion of the $60.0 million revolver can be made at any time through September 2009, when all loans must be repaid and the revolving credit arrangement terminates. The fees for the unused portion of the revolving credit arrangement range from 0.5% to 0.75% (depending on Headwaters’ “total leverage ratio,” as defined). There were no borrowings outstanding under the revolving credit arrangement as of March 31, 2007, or subsequent thereto. The credit agreement also allows for the issuance of letters of credit, provided there is capacity under the revolving credit arrangement. As of March 31, 2007, five stand-by letters of credit totaling $4.4 million were outstanding, with expiration dates ranging from June 2007 to December 2008.

The credit facility contains restrictions and covenants common to such agreements, including limitations on the incurrence of additional debt, investments, merger and acquisition activity, asset sales and liens, annual capital expenditures in excess of $100.0 million annually, and the payment of dividends, among others. In addition, Headwaters must maintain certain leverage and fixed charge coverage ratios, as those terms are defined in the agreements, as follows: i) a total leverage ratio of 3.75:1.0 or less, declining to 3.5:1.0 in 2010; ii) a maximum ratio of consolidated senior funded indebtedness minus subordinated indebtedness to EBITDA of 2.75:1.0, declining to 2.5:1.0 in 2010; and iii) a minimum ratio of EBITDA plus rent payments for the four preceding fiscal quarters to scheduled payments of principal and interest on all indebtedness for the next four fiscal quarters of 1.25:1.0.

As required by the senior secured credit facility, Headwaters entered into agreements to limit its variable interest rate exposure. The agreements effectively fix the LIBOR rate at 3.71% for $150.0 million of the first lien debt through September 8, 2007. Headwaters accounts for these agreements as cash flow hedges, with their fair market value reflected in the consolidated balance sheet as either other assets or other liabilities. The market value of these hedges (and various other cash flow hedges to which Headwaters is a direct or indirect party) at March 31, 2007 was not material. Total comprehensive income, considering all cash flow hedge agreements to which Headwaters is a party, was not materially different from net income for either 2006 or 2007.

2.875% Convertible Senior Subordinated Notes Due 2016 — Headwaters has outstanding $172.5 million of 2.875% convertible senior subordinated notes due June 2016, with interest payable semi-annually. These notes are subordinate to the senior secured debt described above and rank equally with the 2.50% convertible senior subordinated notes due 2014 described below, and any future senior subordinated debt. Holders of the notes may convert the notes into shares of Headwaters’ common stock at a conversion rate of 33.3333 shares per $1,000 principal amount ($30 conversion price), or 5.75 million aggregate shares of common stock, contingent upon certain events. The conversion rate adjusts for events related to Headwaters’ common stock, including common stock issued as a dividend, rights or warrants to purchase common stock issued to all holders of Headwaters’ common stock, and other similar rights or events that apply to all holders of common stock.

The notes are convertible if any of the following five criteria are met: 1) satisfaction of a market price condition which becomes operative if, prior to June 1, 2011, in any calendar quarter the closing price of Headwaters’ common stock exceeds $39 per share for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the calendar quarter, or, at any time on or after June 1, 2011 the closing price of Headwaters’ common stock exceeds $39 per share; 2) a credit rating, if any, assigned to the notes is three or more rating subcategories below the initial rating; 3) the notes trade at less than 98% of the product of the common stock trading price and the number of shares of common stock issuable upon conversion of $1,000 principal amount of the notes, except this provision is not available if the closing common stock price is between 100% and 130% of the current conversion price of the notes; 4) Headwaters calls the notes for redemption; or 5) upon the occurrence of specified corporate transactions.

Headwaters may call the notes for redemption at any time on or after June 1, 2007 and prior to June 4, 2011 if the closing common stock price exceeds 130% of the conversion price for 20 trading days in any consecutive 30-day trading period (in which case Headwaters must provide a “make whole” payment of the present value of all remaining interest payments on the redeemed notes through June 1, 2011). Headwaters may redeem any portion of the notes at any time on or after June 4, 2011. In addition, the holder of the notes has the right to require Headwaters to repurchase all or a portion of the notes on June 1, 2011 or if a fundamental change in common stock has occurred, including termination of trading. Subsequent to June 1, 2011, the notes require an additional interest payment equal to 0.40% of the average trading price of the notes if the trading price equals 120% or more of the principal amount of the notes.

Headwaters includes the additional shares of common stock contingently issuable under the convertible notes in its diluted EPS calculations on an if-converted basis (see Note 8). In January 2007, Headwaters announced that it was planning an exchange offer for the 2.875% convertible senior subordinated notes due 2016, whereby new notes with similar, but not identical, terms, along with an exchange fee, would be issued upon tender of the existing notes. The commencement of an exchange offer has been indefinitely postponed.

12

2.50% Convertible Senior Subordinated Notes Due 2014 — In January 2007, Headwaters issued $160.0 million of 2.50% convertible senior subordinated notes due February 2014, with interest payable semi-annually. These notes are subordinate to the senior secured debt and rank equally with the 2.875% convertible senior subordinated notes due 2016 described above, and any future senior subordinated debt. Total offering costs, including underwriting discounts and commissions, were approximately $5.2 million. The conversion rate for the notes is 33.9236 shares per $1,000 principal amount ($29.48 conversion price), subject to adjustment. Upon conversion, Headwaters will pay cash up to the principal amount of the notes, and shares of common stock to the extent the price of Headwaters’ common stock exceeds the conversion price during a 20-trading-day observation period. The conversion rate is adjusted for certain corporate transactions referred to as “fundamental changes.”

The notes are convertible at the option of the holder prior to December 1, 2013 if any of the following criteria are met:  1) during any fiscal quarter commencing after March 31, 2007, the closing price of Headwaters’ common stock exceeds $38.32 per share for at least 20 trading days during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; 2) during the five-business-day period after any ten-consecutive-trading-day period, the notes trade at less than 98% of the product of the common stock trading price and the number of shares of common stock issuable upon conversion of $1,000 principal amount of the notes; or 3) upon the occurrence of specified corporate transactions. The notes are convertible on or after December 1, 2013 regardless of the foregoing circumstances. Headwaters may not redeem the notes. If Headwaters has a “fundamental change,” holders may require Headwaters to repurchase the notes at a price equal to the principal amount plus any accrued interest. Headwaters filed a shelf registration statement with the SEC to register resales of the notes and the common stock issuable upon conversion of the notes in April 2007, which registration statement was effective upon filing.

In connection with the issuance of the notes, Headwaters entered into convertible note hedge and warrant transactions for the purpose of effectively increasing the common stock conversion price for the notes from $29.48 per share to $35.00 per share. The convertible note hedge terminates upon the maturity of the notes or when none of the notes remain outstanding due to conversion or otherwise. The net pre-tax cost of the hedge and warrant transactions was approximately $11.8 million. Because the contracts are indexed to Headwaters’ common stock and are not considered derivatives, the net cost was accounted for as a decrease in paid-in capital. Headwaters also recorded a deferred tax asset of approximately $16.2 million related to the hedge transaction.

Notes Payable to a Bank — The notes payable to a bank, which were collateralized by certain assets of a subsidiary, were repaid in their entirety during 2007.

Interest — During the three months ended March 31, 2006 and 2007, Headwaters incurred total interest costs of approximately $9.4 million and $9.9 million, respectively, including approximately $1.0 million and $2.6 million, respectively, of non-cash interest expense and approximately $0.2 million and $0.2 million, respectively, of interest costs that were capitalized. During the six months ended March 31, 2006 and 2007, Headwaters incurred total interest costs of approximately $19.4 million and $19.3 million, respectively, including approximately $1.6 million and $3.3 million, respectively, of non-cash interest expense and approximately $0.3 million and $0.5 million, respectively, of interest costs that were capitalized.

Interest income was approximately $0.5 million and $0.6 million during the three months ended March 31, 2006 and 2007, respectively, and $1.4 million and $1.5 million during the six months ended March 31, 2006 and 2007, respectively. The weighted-average interest rate on the face amount of outstanding long-term debt, disregarding amortization of debt issue costs, was approximately 5.7% at September 30, 2006 and 4.3% at March 31, 2007.

7.Income Taxes

Headwaters’ estimated effective income tax rate for the fiscal year ending September 30, 2007, exclusive of discrete items, is 23.0%, which rate was applied to income before income taxes for the six months ended March 31, 2007. Headwaters also recognized a net $1.2 million income tax benefit during the 2007 six-month period for discrete items that did not affect the calculation of the estimated effective income tax rate for the fiscal year. The discrete items primarily consisted of additional tax credits for 2006 and changes in estimated tax liabilities and in reserves related to an IRS examination. The additional tax credits for 2006 resulted from actual phase-out of Section 45K tax credits for calendar 2006 being lower than previously estimated. After consideration of the effect of the discrete items, income tax

13

expense totaled approximately 20.8% of income before income taxes for the six months ended March 31, 2007, compared to 28.0% for the six months ended March 31, 2006. The income tax rates for the three months ended March 31, 2006 and 2007 were 30.8% and 17.0%, respectively.

The effective tax rates for 2006 and 2007 are lower than statutory rates primarily due to tax credits related to two coal-based solid alternative fuel facilities that Headwaters owns and operates, plus Headwaters’ 19% interest in an entity that owns and operates another alternative fuel facility (where Headwaters is not the primary beneficiary). The alternative fuel produced at these three facilities through December 2007 qualifies for tax credits pursuant to Section 45K (formerly Section 29) of the Internal Revenue Code, subject to the uncertainties of phase-out, IRS audit and other risks associated with the tax credits, all as more fully described in Note 9.

Headwaters’ 19% interest in the entity that owns and operates an alternative fuel facility was acquired for payments totaling $15.5 million, of which $5.2 million remains to be paid as of March 31, 2007. This obligation is recorded in other accrued liabilities in the consolidated balance sheet and bears interest at an 8% rate. Headwaters also agreed to make additional payments to the seller based on a pro-rata allocation of the tax credits generated by the facility through December 2007. These additional contractual payments are affected by phase-out and, along with the amortization of the $15.5 million investment, are recorded in other expense in the consolidated statements of income, totaling approximately $5.6 million and $6.7 million for the six months ended March 31, 2006 and 2007, respectively.

The alternative fuel produced at the facility through December 2007 qualifies for tax credits and Headwaters is entitled to receive its pro-rata share of such tax credits generated based upon its ownership percentage. Headwaters has the ability, under certain conditions, to limit its liability under the fixed payment obligations currently totaling approximately $5.2 million; therefore, Headwaters’ obligation to make all of the above-described payments is effectively limited by the tax benefits Headwaters receives.

As a result of actual and projected oil prices for calendar 2007, there could be a partial phase-out of Section 45K tax credits for the calendar year. In calculating an income tax provision for 2007, Headwaters used an estimated phase-out percentage for Section 45K tax credits of 21% for calendar 2007. This estimated phase-out percentage was derived by estimating the calendar 2007 reference price for oil using actual oil prices for January 2007 and published NYMEX oil prices for the months February through December 2007. The monthly NYMEX oil prices were reduced by approximately 10%, which reduction represents Headwaters’ estimate of the relationship between NYMEX oil prices and the average U.S. wellhead oil prices actually used to calculate the annual reference price. The reference price for calendar 2007 was calculated by averaging the 12 months’ actual or estimated oil prices, which average was compared to the estimated phase-out range for calendar 2007 of $56.16 to $70.50 to derive an estimated phase-out percentage.

While the calendar 2007 phase-out percentage can not be finalized at the current time, as of March 31, 2007, the estimated phase-out percentage represents Headwaters’ best estimate of what the phase-out percentage would be, using available information as of that date. The effect on income taxes of any change in the calendar 2007 phase-out percentage from 21% to the actual percentage for the year will be recorded to income tax expense in subsequent periods, when the calendar 2007 actual oil prices and the phase-out range are known. Any such effect could be material to Headwaters’ 2007 and 2008 income tax expense.

9.Commitments and Contingencies

Significant new commitments and ongoing contingencies as of March 31, 2007 not disclosed previously, are as follows.

Acquisitions — During fiscal 2006 and 2007, Headwaters acquired certain assets and assumed certain liabilities of several privately-held companies in the construction materials industry. Pursuant to contractual terms for some of the acquisitions, additional amounts may be payable in the future, based on the achievement of stipulated revenue or earnings targets for periods ending no later than March 2010. If future earn-out consideration is paid, goodwill will be increased accordingly.

Property, Plant and Equipment — As of March 31, 2007, Headwaters was committed to spend approximately $24.5 million on capital projects that were in various stages of completion.

Joint Venture Obligations — Headwaters has entered into various joint ventures with Degussa AG, an international chemical company based in Germany. One of these joint ventures purchased a hydrogen peroxide business located in South Korea. Headwaters is a principal obligor with respect to all non-financial obligations of the joint venture and, with respect to financial obligations of the joint venture, 50% of future plant expansion cost overruns, if any. Headwaters’ investments in its joint ventures with Degussa AG (in which Degussa and Headwaters have equal ownership, voting

15

rights and control) are accounted for using the equity method of accounting and total approximately $18.5 million as of March 31, 2007.

Headwaters owns a 51% interest in a joint venture with Great River Energy, a Minnesota-based power generation and supply cooperative (“GRE”), which was formed to construct, own and operate an ethanol plant in North Dakota (“Blue Flint”). The plant, which commenced operations in February 2007, is expected to produce more than 50 million gallons of ethanol annually. Costs to construct the ethanol plant and fund start-up costs and initial working capital were funded primarily by debt secured by all the assets of Blue Flint, along with capital contributions from Headwaters and GRE. Headwaters has made its required capital contribution. The Blue Flint joint venture, which is not a variable interest entity, is being accounted for using the equity method of accounting because both partners have equal voting rights and control over the joint venture. Headwaters’ investment in the Blue Flint joint venture is approximately $8.6 million as of March 31, 2007.

Legal Matters — Headwaters has ongoing litigation and asserted claims which have been incurred during the normal course of business, including the specific matters discussed below. Headwaters intends to vigorously defend or resolve these matters by settlement, as appropriate. Management does not currently believe that the outcome of these matters will have a material adverse effect on Headwaters’ operations, cash flow or financial position.

Historically, costs paid to outside legal counsel for litigation have generally comprised a majority of Headwaters’ litigation-related costs. During the six months ended March 31, 2007, Headwaters incurred approximately $1.7 million of expense for legal matters, which consisted primarily of costs for outside legal counsel. Headwaters currently believes the range of potential loss for all unresolved matters, excluding costs for outside counsel, is from $1.0 million up to the amounts sought by claimants and has recorded a total liability as of March 31, 2007 of $1.0 million. Claims and damages sought by claimants in excess of this amount are not deemed to be probable. Headwaters’ outside counsel currently believe that unfavorable outcomes of outstanding litigation are neither probable nor remote and declined to express opinions concerning the likely outcomes or liability to Headwaters. It is not possible to estimate what litigation-related costs will be in future periods.

The matters discussed below raise difficult and complex legal and factual issues, and the resolution of these issues is subject to many uncertainties, including the facts and circumstances of each case, the jurisdiction in which each case is brought, and the future decisions of juries, judges, and arbitrators. Therefore, although management believes that the claims asserted against Headwaters in the named cases lack merit, there is a possibility of material losses in excess of the amounts accrued if one or more of the cases were to be determined adversely against Headwaters for a substantial amount of the damages asserted. It is possible that a change in the estimates of probable liability could occur, and the changes could be material. Additionally, as with any litigation, these proceedings require that Headwaters incur substantial costs, including attorneys’ fees, managerial time, and other personnel resources and costs in pursuing resolution.

McEwan.  In 1995, Headwaters granted stock options to a member of its board of directors, Lloyd McEwan. The director resigned from the board in 1996. Headwaters has declined McEwan’s attempts to exercise most of the options on grounds that the options terminated. In June 2004, McEwan filed a complaint in the Fourth District Court for the State of Utah against Headwaters alleging breach of contract, breach of implied covenant of good faith and fair dealing, fraud, and misrepresentation. McEwan seeks declaratory relief as well as compensatory damages in the approximate amount of $2.8 million and punitive damages. Headwaters has filed an answer denying McEwan’s claims and has asserted counterclaims against McEwan. Because resolution of the litigation is uncertain, legal counsel cannot express an opinion as to the ultimate amount of liability or recovery.

Boynton.  In October 1998, Headwaters entered into a technology purchase agreement with James G. Davidson and Adtech, Inc. The transaction transferred certain patent and royalty rights to Headwaters related to a synthetic fuel technology invented by Davidson. (This technology is distinct from the technology developed by Headwaters.) This action is factually related to an earlier action brought by certain purported officers and directors of Adtech, Inc. That action was dismissed by the United States District Court for the Western District of Tennessee and the District Court’s

16

order of dismissal was affirmed on appeal. In the current action, the allegations arise from the same facts, but the claims are asserted by certain purported stockholders of Adtech. In June 2002, Headwaters received a summons and complaint from the United States District Court for the Western District of Tennessee alleging, among other things, fraud, conspiracy, constructive trust, conversion, patent infringement and interference with contract arising out of the 1998 technology purchase agreement entered into between Davidson and Adtech on the one hand, and Headwaters on the other. The plaintiffs seek declaratory relief and compensatory damages in the approximate amount of between $15.0 million and $25.0 million and punitive damages. In February 2006, the District Court dismissed all claims against Headwaters. Also in February 2006, plaintiffs filed their notice of appeal to the United States Court of Appeals for the Sixth Circuit. In June 2006, the appeal was transferred to the United States Court of Appeals for the Federal Circuit. Because the resolution of the litigation is uncertain, legal counsel cannot express an opinion as to the ultimate amount, if any, of Headwaters’ liability.

Headwaters Construction Materials Matters.  There are litigation and pending and threatened claims made against certain subsidiaries of Headwaters Construction Materials (“HCM”) with respect to several types of exterior finish systems manufactured and sold by its subsidiaries for application by contractors on residential and commercial buildings. Typically, litigation and these claims are controlled by such subsidiaries’ insurance carriers. The plaintiffs or claimants in these matters have alleged that the structures have suffered damage from latent or progressive water penetration due to some alleged failure of the building product or wall system. Some claims involve alleged defects associated with components of an Exterior Insulating and Finish System (“EIFS”) which was produced for a limited time (through 1997) by Best Masonry & Tool Supply and Don’s Building Supply. There is a 10-year projected claim period following discontinuation of the product. Other claims involve alleged liabilities associated with certain stucco products which are still produced and sold by certain subsidiaries of HCM.

Typically, the claims cite damages for alleged personal injuries and punitive damages for alleged unfair business practices in addition to asserting more conventional damage claims for alleged economic loss and damage to property. To date, claims made against such subsidiaries have been paid by their insurers, with the exception of minor deductibles, although such insurance carriers typically have issued “reservation of rights” letters.  None of the cases has gone to trial. While, to date, none of these proceedings have required that HCM incur substantial costs, there is no guarantee of insurance coverage or continuing coverage. These and future proceedings may result in substantial costs to HCM, including attorneys’ fees, managerial time and other personnel resources and costs. Adverse resolution of these proceedings could have a materially negative effect on HCM’s business, financial condition, and results of operation, and its ability to meet its financial obligations. Although HCM carries general and product liability insurance, HCM cannot assure that such insurance coverage will remain available, that HCM’s insurance carrier will remain viable, or that the insured amounts will cover all future claims in excess of HCM’s uninsured retention. Future rate increases may also make such insurance uneconomical for HCM to maintain. In addition, the insurance policies maintained by HCM exclude claims for damages resulting from exterior insulating finish systems, or EIFS, that have manifested after March 2003. Because resolution of the litigation and claims is uncertain, legal counsel cannot express an opinion as to the ultimate amount, if any, of HCM’s liability.

Other.  Headwaters and its subsidiaries are also involved in other legal proceedings that have arisen in the normal course of business.

Section 45K Matters — A material amount of Headwaters’ consolidated revenue and net income is derived from license fees and sales of chemical reagents, both of which depend on the ability of licensees and other customers to manufacture and sell qualified synthetic fuel that generates tax credits under Section 45K (formerly Section 29) of the Internal Revenue Code. Headwaters also claims Section 45K tax credits for synthetic fuel sales from facilities in which it owns an interest. From time to time, issues arise as to the availability of tax credits and, with the increased price of oil, the phase-out of credits, including the following items.

Phase-Out.  Section 45K tax credits are subject to phase-out after the average annual U.S. wellhead oil price (“reference price”) reaches a beginning phase-out threshold price, and are eliminated entirely if the reference price reaches the full phase-out price. Historically, the reference price has trended somewhat lower than published market prices for oil. For

calendar 2006, the reference price was $59.69 per barrel and the phase-out range began at $55.06 and would have fully phased out tax credits at $69.12 per barrel. Therefore, there was a partial phase-out of tax credits for calendar 2006 of approximately 33%.

For calendar 2007, Headwaters estimates that the phase-out range (computed by increasing the 2006 inflation adjustment factor by 2%) begins at $56.16 and completes phase-out at $70.50 per barrel. As described in more detail in Note 7, Headwaters estimated a phase-out percentage for Section 45K tax credits for calendar 2007 of 21%, using available information as of March 31, 2007. It is certain that the estimated phase-out percentage for calendar 2007 will change during the year.

In an environment of high oil prices, the risk of phase-out increases. Headwaters’ customers and licensees make their own assessments of phase-out risk. When customers and licensees have perceived a potential negative financial impact from phase-out, they have reduced or stopped synthetic fuel production or required Headwaters to share in the costs associated with phase-out. Headwaters makes similar assessments with respect to the continued operation of its own synthetic fuel production facilities. As of March 31, 2007, all of Headwaters’ licensees are producing synthetic fuel, but most licensees stopped production for a period of time in calendar 2006. These events have materially adversely affected both the amount and timing of recognition of Headwaters’ revenue, net income and cash flow, and will likely have a material adverse effect in future periods as well.

Certain accounting rules limit revenue recognition to amounts that are “fixed or determinable.” The amount of license fee revenue recognized by Headwaters during fiscal 2006 and thus far in fiscal 2007 was negatively affected by reduced revenues being recognized for certain licensees whose license agreements call for Headwaters to be paid a portion of the tax credits earned by the licensee. Due to uncertainties related to phase-out for calendar 2006 and 2007 and other licensee-specific factors, revenue recognition was deferred for certain licensees during fiscal 2006 and is also currently being deferred for certain licensees in 2007. However, due to the recent publication of the 2006 reference price and the phase-out range for the year, finalization of calendar 2006 phase-out was made possible. Due to the availability of this information and the clarification of other licensee-specific factors, certain calendar 2006 and prior year license fee revenue totaling approximately $26.5 million was recognized during the quarter ended March 31, 2007. The amounts recognized related to periods ending on or prior to December 31, 2006 and were recognized at this time because they met the “fixed or determinable” recognition criterion and it is remote that any negative adjustment will be required in the future. As of March 31, 2007, most license fee revenue that has not been recognized relates to the quarter ended March 31, 2007. This unrecognized revenue, which as of March 31, 2007 could total more than $12.0 million (calculated based on licensee-reported data and assuming 21% phase-out of Section 45K tax credits for calendar 2007), will not be recognized until such time as the amounts become “fixed or determinable.”

Legislation.  By law, Section 45K tax credits for synthetic fuel produced from coal expire on December 31, 2007. In addition, there have been initiatives from time to time to consider the early repeal or modification of Section 45K, including a bill introduced as recently as January 2007, and there may be additional initiatives introduced in Congress in calendar 2007. When Section 45K expires on December 31, 2007 or if it is repealed or adversely modified, additional synthetic fuel facilities will probably either close or substantially curtail production. Given current prices of coal and the costs of synthetic fuel production, Headwaters does not believe that production of synthetic fuel will be profitable absent the tax credits. In addition, if Headwaters’ licensees close their facilities or materially reduce production activities (whether after December 31, 2007, or upon earlier repeal or adverse modification of Section 45K, or for any other reason), it would have a further material adverse effect on the revenue, net income and cash flow of Headwaters, in addition to the current material adverse effect caused by phase-out concerns.

IRS Audits.  Licensees are subject to audit by the IRS. The IRS may challenge whether Headwaters’ licensees satisfy the requirements of Section 45K or applicable Private Letter Rulings, including placed-in-service requirements, or may attempt to disallow Section 45K tax credits for some other reason. The IRS has initiated audits of certain licensee-taxpayers who claimed Section 45K tax credits and will continue the audit process in the future. The inability of a licensee to claim Section 45K tax credits would reduce Headwaters’ future income from the licensee. In addition, the IRS may audit Headwaters’ tax credits claimed for synthetic fuel sold from the facilities in which it owns an interest.

18

Senate Permanent Subcommittee on Investigations.  In October 2003, the Permanent Subcommittee on Investigations of the Government Affairs Committee of the United States Senate issued a notification of pending investigations. The notification listed the synthetic fuel tax credit as a new item. In February 2006, the Subcommittee described its investigation as follows: “The Subcommittee is continuing its investigation [of] tax credits claimed under Section 29 [now Section 45K] of the Internal Revenue Code for the sale of coal-based synthetic fuels. This investigation is examining the utilization of these tax credits, the nature of the technologies and fuels created, the use of these fuels, and others [sic] aspects of Section 29. The investigation will also address the IRS’ administration of Section 29 tax credits.” The Subcommittee conducted numerous interviews and received large volumes of data between December 2003 and March 2004. Since that time, to Headwaters’ knowledge, there has been little activity regarding the investigation. Headwaters cannot make any assurances as to the timing or ultimate outcome of the Subcommittee’s investigation, nor can Headwaters predict whether Congress or others may conduct investigations of Section 45K tax credits in the future. Renewed activity in the Subcommittee investigation, if it occurs, may have a material adverse effect on the willingness of current owners to operate their facilities, and may materially adversely affect Headwaters’ revenue, net income and cash flow.

ITEM 2.   MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes included in this Form 10-Q. Our fiscal year ends on September 30 and unless otherwise noted, references to 2006 refer to our fiscal quarter and/or six month period ended March 31, 2006 and references to 2007 refer to our fiscal quarter and/or six month period ended March 31, 2007. Other references to years refer to our fiscal years, unless otherwise noted.

Overview

Consolidation and Segments. The consolidated financial statements include the accounts of Headwaters, all of our subsidiaries and other entities in which we have a controlling interest. All significant intercompany transactions and accounts are eliminated in consolidation. As described in more detail in our December 31, 2006 Form 10-Q, during that quarter, we acquired 100% of the ownership interests of a privately-held company in the construction materials business. Operating results for the acquired business subsequent to the acquisition date have been included in our consolidated results for 2007 and were not material.

We currently operate in two industries and report three business segments, the construction materials and CCPs segments in the building materials industry, and the alternative energy segment in the energy industry. In the construction materials segment, we design, manufacture, and sell architectural stone and resin-based exterior siding accessories (such as shutters, mounting blocks, and vents) and related products. Revenues consist of sales to wholesale and retail distributors, contractors and other users of building products. We are also a nationwide leader in the management and marketing of CCPs. Revenues in the CCP segment consist primarily of fly ash and other product sales. In the alternative energy segment, we are focused on reducing waste and increasing the value of energy feedstocks, primarily in the areas of low-value coal and oil. Revenue for the alternative energy segment consists primarily of sales of chemical reagents and license fees.

Operations and Strategy.  During the past several years, we have executed on our two-fold plan of maximizing cash flow from our existing operating business units and diversifying from over-reliance on the legacy alternative energy segment Section 45K (formerly Section 29) business. With the addition and expansion of our CCP management and marketing business through acquisitions in 2002 and in 2004, and the growth of our construction materials business, through several large and small acquisitions in 2004, 2006 and 2007, we have achieved revenue growth and diversification in three business segments. Because we also incurred increased indebtedness to make strategic acquisitions, one of our ongoing financial objectives is to continue to focus on increased cash flows to reduce debt.

A material amount of our consolidated revenue and net income is derived from license fees and sales of chemical reagents, both of which depend on the ability of licensees and other customers to manufacture and sell qualified synthetic fuel that generates tax credits under Section 45K (formerly Section 29) of the Internal Revenue Code. We also claim Section 45K tax credits for synthetic fuel sales from facilities in which we own an interest. From time to time, issues arise as to the availability of tax credits and, with the increased price of oil, the phase-out of credits.

By law, Section 45K tax credits for synthetic fuel produced from coal expire on December 31, 2007. In addition, Section 45K tax credits are subject to phase-out after the average annual U.S. wellhead oil price (“reference price”) reaches a beginning phase-out threshold price, and are eliminated entirely if the reference price reaches the full phase-out price. There was no phase-out of tax credits for calendar 2005; however, as a result of high oil prices in calendar 2006, there was a partial phase-out of tax credits for calendar 2006 of approximately 33%. In addition, phase-out of Section 45K for calendar 2007 is also possible. As of March 31, 2007, all of our licensees are producing synthetic fuel, but most licensees stopped production for a period of time in calendar 2006. These events have materially adversely affected both the amount and timing of recognition of our revenue, net income and cash flow, and will likely have a material adverse effect in future periods as well. Reference is made to notes 7 and 9 to the consolidated financial statements where there is more information on phase-out and other uncertainties related to Section 45K tax credits that have affected our business in 2007 and that will continue to affect our business for the remainder of calendar 2007.

Our acquisition strategy targets businesses that are leading players in their respective industries, that enjoy healthy operating margins and that are not overly capital intensive, thus providing additional cash flow that complements the financial performance of our existing businesses. In addition, in fiscal 2006, we began to acquire small companies with innovative products that can be marketed using our existing distribution channels. We are also committed to continuing to invest in research and development activities that are focused on energy-related technologies and nanotechnology. We participate in a joint venture which operates an ethanol plant located in North Dakota, and we are also investing in other alternative energy projects such as coal cleaning and the use of nanocatalysts to engineer coal for emissions reduction and to enhance the refining of heavy crude oils into lighter transportation fuels.

20

As a result of our CCPs and construction materials businesses, we are affected by seasonality, with the highest revenue and profitability produced in the June and September quarters. With CCPs, our strategy is to continue to negotiate long-term contracts so that we can invest in transportation and storage infrastructure for the marketing and sale of CCPs. We also intend to continue our efforts to expand usage of high-value CCPs and develop uses for lower-value CCPs, including the expanded use of CCPs in our construction materials businesses and the industry in general.

In fiscal 2005 and 2006, we focused on the integration of our large 2004 acquisitions, including the marketing of diverse construction materials products through our national distribution network. We became highly leveraged as a result of those acquisitions, but have reduced our outstanding debt since that time through cash generated from operations, from an underwritten public offering of common stock and from proceeds from settlement of litigation. We intend to continue to focus on repaying long-term debt while continuing to look for diversification opportunities within prescribed parameters.

Three Months Ended March 31, 2007 Compared to Three Months Ended March 31, 2006

The information set forth below compares our operating results for the quarter ended March 31, 2007 (“2007”) with operating results for the quarter ended March 31, 2006 (“2006”).

Revenue.  Total revenue for 2007 increased by $4.4 million or 2% to $274.1 million as compared to $269.7 million for 2006. The major components of revenue are discussed in the sections below.

Construction Materials Segment.  Sales of construction materials during 2007 were $115.5 million with a corresponding direct cost of $87.2 million. Sales of construction materials during 2006 were $131.7 million with a corresponding direct cost of $91.2 million. The decrease in sales of construction materials during 2007 was due primarily to the effects of a depressed residential housing and remodeling market which impacted sales across most of our product lines. The housing market slowdown also was the primary reason for the decline in gross margin percentage from 2006 to 2007.  Because a substantial amount of our revenues in this segment are dependent on the housing market, we anticipate similar impact in future periods until the cycle reverses.

CCP Segment.  CCP revenues for 2007 were $62.1 million with a corresponding direct cost of $46.8 million. CCP revenues for 2006 were $58.5 million with a corresponding direct cost of $46.3 million. The increase in CCP revenues and in the gross margin percentage during 2007 were due primarily to a combination of continued strong demand for CCPs and upward pricing trends in most concrete markets. The growth in demand for CCPs is due in part to certain regional shortages of portland cement for which CCPs are a substitute, which can result in an increased percentage of CCPs being used in concrete. The cement shortages also resulted in increased prices for CCPs in several markets.

Alternative Energy Segment.  Our alternative energy segment revenue consists primarily of chemical reagent sales, license fee revenue related to our solid alternative fuel technologies, and to a lesser extent, sales of synthetic fuel from two solid alternative fuel production facilities that we own. The major components of revenue for the alternative energy segment are discussed in the sections below.

Sales of Chemical Reagents.  Chemical reagent sales during 2007 were $46.0 million with a corresponding direct cost of $37.3 million. Chemical reagent sales during 2006 were $49.9 million with a corresponding direct cost of $37.7 million. Chemical reagent sales in 2007 were lower than in 2006 primarily due to reduced synthetic fuel production by two of our licensees. It is not possible to predict the trend for sales of chemical reagents in future periods because synfuel production by our licensees and other customers is subject to decisions based on future oil prices. The gross margin percentage for 2007 of 19% was lower than the 2006 gross margin percentage of 24% due primarily to increases in the cost of product, which in turn was related to increases in the costs of petroleum-based materials. Subject to crude oil prices and other factors, we currently believe reagent margins in fiscal 2007 will be in the 17% range.

License Fees.  During 2007, we recognized license fee revenue totaling $42.2 million, an increase of $25.9 million from $16.3 million of license fee revenue recognized during 2006. Certain accounting rules limit revenue recognition to amounts that are “fixed or determinable.” The amount of license fee revenue recognized in 2006 and 2007 was negatively affected by reduced revenues being recognized for certain licensees whose license agreements call for us to be paid a portion of the tax credits earned by the licensee. Due to uncertainties related to phase-out for calendar 2006 and 2007 and other licensee-specific factors, revenue recognition was deferred for certain licensees during 2006 and is also currently being deferred for certain licensees in fiscal 2007. However, due to the recent publication of the 2006 reference price and the phase-out range for the year, finalization of calendar 2006 phase-out was made possible. Due to the availability of this information and the clarification of other licensee-specific factors, certain calendar 2006 and prior year license fee revenue totaling approximately $26.5 million was recognized during 2007. The amounts recognized related to periods ending on or prior to December 31, 2006 and were recognized at this time because they met the “fixed or determinable” recognition criterion and it is remote that any negative adjustment will be required in the future. As of March 31, 2007, most license fee revenue that has not been recognized relates to the quarter ended March 31, 2007. This unrecognized revenue, which as of March 31, 2007

21

could total more than $12.0 million (calculated based on licensee-reported data and assuming 21% phase-out of Section 45K tax credits for calendar 2007), will not be recognized until such time as the amounts become “fixed or determinable.” Reference is made to our policy disclosures contained in Note 2 to the consolidated financial statements and in “Management’s Discussion and Analysis” in our Form 10-K, as well as information in Note 9 to the consolidated financial statements in this Form 10-Q and in the overview above.

Other Alternative Energy Segment Revenues.  The majority of other alternative energy segment revenue is comprised of sales of synthetic fuel, which during 2007 were $6.6 million with a corresponding direct cost of $7.4 million. Sales of synthetic fuel during 2006 were $11.8 million with a corresponding direct cost of $13.8 million. The decrease in sales of synthetic fuel from 2006 to 2007 was due primarily to marketing constraints and high inventory levels at December 31, 2006. Revenue from the sale of synthetic fuel has a negative gross margin, which is more than compensated for by the income tax credits expected to be earned from the sales of the synthetic fuel.

Amortization and Research and Development Expenses.  The change in amortization expense ($0.3 million) from 2006 to 2007 was not material. Research and development expense increased by $2.0 million from 2006 to 2007 primarily because of increased spending in our joint research efforts with Degussa related to hydrogen peroxide (see Note 9) and in developmental efforts related to our nanotechnologies.

Selling, General and Administrative Expenses.  These expenses increased $5.5 million, or 17% to $37.8 million for 2007 from $32.3 million for 2006. The increase in 2007 was due primarily to a $3.0 million increase in litigation-related costs, $1.6 million of increased payroll costs, and $0.8 million of increased incentive pay. The increase in litigation costs was due to a net credit recorded in 2006 because of positive developments in certain legal matters. Those developments resulted in reduced likelihood of ultimate legal liability and the reversal of previously expensed litigation costs. A majority of the increase in payroll costs relates to growth initiatives at the operating business unit level, and the increased incentive pay relates to improved overall operating results in 2007 as compared to 2006.

Other Income and Expense.  During 2007, we reported net other expense of $12.7 million compared to net other expense of $11.1 million during 2006. The change of $1.6 million was attributable to an increase in net interest expense of $0.4 million and an increase in other expenses of $1.2 million. Net interest expense increased from $8.7 million in 2006 to $9.1 million in 2007, due primarily to $2.0 million of accelerated amortization of debt issue costs related to early repayments of higher-rate senior debt, largely offset by the lower interest rate (2.50%) on the $160.0 million of convertible senior subordinated notes issued in January 2007, the proceeds of which were used primarily to make the early senior debt repayments.

The increase in other expenses of $1.2 million consisted primarily of an increase in costs related to our investment in the coal-based solid alternative fuel production facility described in Note 7 to the consolidated financial statements.

Income Tax Provision.  Our estimated effective income tax rate for the fiscal year ending September 30, 2007 is 23.0%, which rate was applied to income before income taxes for the six months ended March 31, 2007. We also recognized a net $2.2 million income tax benefit in 2007 for discrete items that did not affect the calculation of the estimated effective income tax rate for the fiscal year. The discrete items primarily consisted of additional tax credits for fiscal 2006 resulting from actual phase-out of Section 45K tax credits for calendar 2006 being lower than previously estimated. After consideration of the effect of the discrete items, income tax expense totaled approximately 17.0% of income before income taxes in 2007, compared to 30.8% in 2006. The effective tax rates for 2006 and 2007 are lower than statutory rates primarily due to tax credits related to the alternative fuel facilities that we own or have an interest in, all as described in Note 7 to the consolidated financial statements. Excluding the effect of the tax credits, our estimated effective tax rate for 2007 would be approximately 38%.

Also as described in Notes 7 and 9 to the consolidated financial statements, while we have estimated a phase-out percentage for Section 45K tax credits for calendar 2007 using available information as of March 31, 2007, it is certain that our estimated phase-out percentage will change during the year. The effect on income taxes of changes in the estimated phase-out percentage for calendar 2007 will be recorded to income tax expense in subsequent periods, when the calendar 2007 actual oil prices are known. Any such effect could be material to our 2007 and 2008 income tax expense.

The calculation of tax liabilities involves uncertainties in the application of complex tax regulations in multiple jurisdictions. For example, we are currently under IRS audit for 2003 and 2004. We recognize potential liabilities for anticipated tax audit issues in the U.S. and state tax jurisdictions based on estimates of whether, and the extent to which, additional taxes and interest will be due. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when it is determined the liabilities are no longer probable or necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.

Six Months Ended March 31, 2007 Compared to Six Months Ended March 31, 2006

The information set forth below compares our operating results for the six months ended March 31, 2007 (“2007”) with operating results for the six months ended March 31, 2006 (“2006”).

Revenue.  Total revenue for 2007 decreased by $1.2 million or less than 1% to $549.0 million as compared to $550.2 million for 2006. The major components of revenue are discussed in the sections below.

Construction Materials Segment.  Sales of construction materials during 2007 were $238.3 million with a corresponding direct cost of $177.7 million. Sales of construction materials during 2006 were $261.7 million with a corresponding direct cost of $180.9 million. The decrease in sales of construction materials during 2007 was due primarily to the effects of a depressed residential housing and remodeling market which impacted sales across most of our product lines. The housing market slowdown also was the primary reason for the decline in gross margin percentage from 2006 to 2007.

CCP Segment.  CCP revenues for 2007 were $131.3 million with a corresponding direct cost of $96.2 million. CCP revenues for 2006 were $123.7 million with a corresponding direct cost of $95.3 million. The increase in CCP revenues and in the gross margin percentage during 2007 were due primarily to a combination of continued strong demand for CCPs and upward pricing trends in most concrete markets. In addition, weather conditions in the south central region of the United States have generally been favorable in 2007. The growth in demand for CCPs is due in part to certain regional shortages of portland cement for which CCPs are a substitute. The cement shortages also resulted in increased prices for CCPs in several markets.

Alternative Energy Segment.  Our alternative energy segment revenue consists primarily of chemical reagent sales, license fee revenue related to our solid alternative fuel technologies, and to a lesser extent, sales of synthetic fuel from two solid alternative fuel production facilities that we own. The major components of revenue for the alternative energy segment are discussed in the sections below.

Sales of Chemical Reagents.  Chemical reagent sales during 2007 were $90.5 million with a corresponding direct cost of $72.8 million. Chemical reagent sales during 2006 were $94.4 million with a corresponding direct cost of $71.1 million. Chemical reagent sales in 2007 were lower than in 2006 primarily due to reduced synthetic fuel production by two of our licensees. The gross margin percentage for 2007 of 20% was lower than the 2006 gross margin percentage of 25% due primarily to increases in the cost of product, which in turn was related to increases in the costs of petroleum-based materials.

License Fees.  During 2007, we recognized license fee revenue totaling $64.5 million, an increase of $20.0 million from $44.5 million of license fee revenue recognized during 2006. The amount of license fee revenue recognized in 2006 and 2007 was negatively affected by reduced revenues being recognized for certain licensees whose license agreements call for us to be paid a portion of the tax credits earned by the licensee. Due to uncertainties related to phase-out for calendar 2006 and 2007 and other licensee-specific factors, revenue recognition was deferred for certain licensees during 2006 and is also currently being deferred for certain licensees in fiscal 2007. However, due to the recent publication of the 2006 reference price and the phase-out range for the year, finalization of calendar 2006 phase-out was made possible. Due to the availability of this information and the clarification of other licensee-specific factors, certain prior period license fee revenue totaling approximately $26.5 million was recognized during 2007. The amounts recognized related to periods ending on or prior to December 31, 2006 and were recognized at this time because they met the “fixed or determinable” recognition criterion and it is remote that any negative adjustment will be required in the future. Partially offsetting the $26.5 million increase in license fee revenue was a $4.5 million reduction in license fees in 2007 related to one of our licensees for which we are currently deferring revenue. The license fees from this licensee were not deferred in 2006.

Other Alternative Energy Segment Revenues.  The majority of other alternative energy segment revenue is comprised of sales of synthetic fuel, which during 2007 were $21.5 million with a corresponding direct cost of $24.7 million. Sales of synthetic fuel during 2006 were $23.3 million with a corresponding direct cost of $27.0 million. The decrease in sales of synthetic fuel from 2006 to 2007 was due primarily to marketing constraints. Revenue from the sale of synthetic fuel has a negative gross margin, which is more than compensated for by the income tax credits expected to be earned from the sales of the synthetic fuel.

Amortization and Research and Development Expenses.  The change in amortization expense ($0.5 million) from 2006 to 2007 was not material. Research and development expense increased by $2.8 million from 2006 to 2007 primarily because of increased spending in our joint research efforts with Degussa related to hydrogen peroxide and in developmental efforts related to our nanotechnologies.

Selling, General and Administrative Expenses.  These expenses increased $7.0 million, or 10% to $74.3 million for 2007 from $67.3 million for 2006. The increase in 2007 was due primarily to a $2.7 million increase in litigation-related costs, $3.4 million of increased payroll costs, and $0.9 million of long-term incentive pay expensed in 2007. The increase in litigation costs was due to a net credit recorded in 2006 because of positive developments in certain legal matters. Those

23

developments resulted in reduced likelihood of ultimate legal liability and the reversal of previously expensed litigation costs. A majority of the increase in payroll costs relates to growth initiatives at the operating business unit level, and the increased long-term incentive pay relates to improved performance at certain operating business units.

Other Income and Expense.  During 2007, we reported net other expense of $23.5 million compared to net other expense of $23.2 million during 2006. The change of $0.3 million was attributable to a decrease in net interest expense of $0.4 million and an increase in other expenses of $0.7 million. Net interest expense decreased from $17.7 million in 2006 to $17.3 million in 2007, due primarily to the lower interest rate (2.50%) on the $160.0 million of convertible senior subordinated notes issued in January 2007, and lower average levels of long-term debt in 2007 as compared to 2006. The decrease in interest expense caused by those factors was largely offset by $2.0 million of accelerated amortization of debt issue costs related to early repayments of senior debt in 2007, which early repayments were funded primarily by net proceeds from the new lower-rate convertible notes.

The increase in other expenses of $0.7 million consisted primarily of an increase in costs related to our investment in the coal-based solid alternative fuel production facility described in Note 7 to the consolidated financial statements.

Income Tax Provision.  Our estimated effective income tax rate for the fiscal year ending September 30, 2007 is 23.0%, which rate was applied to income before income taxes for the six months ended March 31, 2007. We also recognized a net $1.2 million income tax benefit in 2007 for discrete items that did not affect the calculation of the estimated effective income tax rate for the fiscal year. The discrete items primarily consisted of additional tax credits for fiscal 2006 and changes in estimated tax liabilities and in reserves related to an IRS examination. The additional tax credits for fiscal 2006 resulted from actual phase-out of Section 45K tax credits for calendar 2006 being lower than previously estimated. After consideration of the effect of the discrete items, income tax expense totaled approximately 20.8% of income before income taxes for 2007, compared to 28.0% for 2006. The effective tax rates for 2006 and 2007 are lower than statutory rates primarily due to tax credits related to the alternative fuel facilities that we own or have an interest in, all as described in Note 7 to the consolidated financial statements.

Impact of Inflation and Related Matters

Our operations have been impacted by i) rising costs for chemical reagents in the alternative energy segment; ii) increased cement, polypropylene and poly-vinyl chloride costs in the construction materials segment; iii) increased fuel costs that have affected transportation costs in most of our business units; and iv) certain regional shortages of cement and aggregate materials. The increased costs of chemical reagents, polypropylene, poly-vinyl chloride and fuel are directly related to the increase in prices of natural gas, oil and other petroleum-based materials. The increased costs of cement are caused primarily by a lack of adequate supplies in some regions of the U.S.

We have been successful in passing on some, but not all, of the increased material and transportation costs to customers. It is not possible to predict the future trend of material and transportation costs, nor our ability to pass on any future price increases to customers. It is also not possible to predict the impact of potential future cement supply shortages on our ability to procure needed supplies in our construction materials business.

Liquidity and Capital Resources

Summary of Cash Flow Activities.  Net cash provided by operating activities during the six months ended March 31, 2007 (“2007”) was $42.0 million compared to $135.2 million during the six months ended March 31, 2006 (“2006”). The primary reason for the change in cash provided by operations from 2006 to 2007 was the collection in 2006 of a $70.0 million receivable related to the litigation settlement reached with AJG in 2005. In 2007, the primary investing activities consisted of payments for an acquisition and the purchase of property, plant and equipment. 2007 financing activities consisted primarily of the issuance of a new series of convertible senior subordinated notes and the early repayment of a portion of our senior debt. In 2006, the primary investing activity consisted of the purchase of property, plant and equipment and the primary financing activity consisted of repayments of long-term debt. More details about our investing and financing activities are provided in the following paragraphs.

Investing Activities.  Total expenditures for property, plant and equipment in 2007 were not materially different from 2006. Most of the capital expenditures in both periods were incurred by the construction materials segment; however, in 2007, a higher proportion of total capital expenditures were incurred by the alternative energy segment as compared to 2006. A significant portion of our planned future capital expenditures represent expansion of operations, rather than maintenance of operating capacity. Capital expenditures in fiscal 2007 are currently expected to exceed the fiscal 2006 amount, primarily due to growth initiatives in the alternative energy segment. Capital expenditures are limited by our senior debt covenants to $100.0 million annually; however, the cumulative unused amounts of annual capital expenditures limits can be carried forward and used in subsequent years. As of September 30, 2006, we had approximately $25.4 million of unused amounts of capital

24

expenditures from prior years and as of March 31, 2007, we were committed to spend approximately $24.5 million on capital projects that were in various stages of completion, primarily in the alternative energy segment.

We intend to continue to expand our business through growth of existing operations, commercialization of technologies currently being developed, and strategic acquisitions of products or entities that expand our current operating platform. Acquisitions are an important part of our business strategy and to that end, we routinely review potential complementary acquisitions, including those in the areas of construction materials, CCP marketing, and coal and catalyst technologies. It is possible that some portion of future cash and cash equivalents and/or proceeds from the issuance of stock or debt will be used to fund acquisitions of complementary businesses in the chemical, energy, building products and related industries. The senior secured credit agreement limits acquisitions in the aggregate to $50.0 million of cash consideration and $20.0 million of non-cash consideration annually, with no more than $30.0 million of cash consideration for any one acquisition, unless our “total leverage ratio,” as defined, is less than or equal to 3.50:1.0, after giving effect to an acquisition, in which case the foregoing limitations do not apply. The senior secured credit agreement also limits the amount we can invest in joint ventures and other less than 100%-owned entities.

In 2007, we acquired 100% of the ownership interests of a privately-held company in the construction materials business. Total consideration paid of approximately $53.0 million consisted primarily of cash. Pursuant to contractual terms, an additional amount may be payable in the future, based on the achievement of a stipulated earnings target for the 12 months ending September 30, 2007. During fiscal 2006, we acquired certain assets and assumed certain liabilities of several privately-held companies in the construction materials industry. Pursuant to contractual terms for some of the acquisitions, additional amounts may be payable in the future, based on the achievement of stipulated revenue or earnings targets for periods ending no later than March 2010. If future earn-out consideration is paid, goodwill will be increased accordingly.

Reference is made to Note 9 to the consolidated financial statements for a discussion of our investments in joint ventures which are accounted for using the equity method of accounting.

Financing Activities.  In 2006, financing activities consisted primarily of the repayment of long-term debt. In 2007, as described in more detail in Note 6 to the consolidated financial statements, we issued $160.0 million of 2.50% convertible senior subordinated notes due February 2014. Substantially all of the net proceeds of approximately $154.8 million, along with $5.0 million of available cash, were used to repay $152.8 million of senior debt and the remaining balance (approximately $7.0 million) of notes payable to a bank. We may, in the future, make optional prepayments of the senior debt depending on actual cash flows, our current and expected cash requirements and other applicable factors we deem to be  significant.

Due to covenants associated with our senior debt, we currently have limitations on our ability to obtain significant additional amounts of long-term debt. However, we have historically experienced strong positive cash flow from operations and in fiscal 2005 issued common stock which together has enabled us to repay a substantial amount of our long-term debt prior to scheduled maturities. We expect our positive cash flow to continue in the future and also have the ability to access the equity markets if necessary.

In January 2007, we announced that we were planning an exchange offer for our 2.875% convertible senior subordinated notes due 2016, whereby new notes with similar, but not identical, terms, along with an exchange fee, would be issued upon tender of the existing notes. The commencement of an exchange offer has been indefinitely postponed.

Reference is made to Note 6 to the consolidated financial statements for detailed information about our outstanding long-term debt, interest rate hedges, and compliance with debt covenants, as well as the available $60.0 million revolving credit arrangement. Subject to obtaining additional revolving loan commitments, we can increase the revolving credit limit to $100.0 million. The senior credit facility contains restrictions and covenants common to such agreements, including limitations on the incurrence of additional debt, investments, merger and acquisition activity, asset sales and liens, annual capital expenditures in excess of $100.0 million annually, and the payment of dividends, among others. In addition, we must maintain certain leverage and fixed charge coverage ratios. We are in compliance with all debt covenants as of March 31, 2007.

In 2007, cash proceeds from the exercise of options and employee stock purchases totaled $1.6 million, compared to $6.4 million in 2006. Option exercise activity is primarily dependent on our stock price and is not predictable. To the extent non-qualified stock options are exercised, or there are disqualifying dispositions of shares obtained upon the exercise of incentive stock options, we receive an income tax deduction generally equal to the income recognized by the optionee. Such amounts, reflected in cash flows from financing activities in the consolidated statements of cash flows, were not material in 2006 or 2007.

Working Capital.  As of March 31, 2007, our working capital was $125.2 million. We expect operations to produce positive cash flow in future periods and believe working capital, along with available borrowings under the revolving credit arrangement, will be sufficient for operating needs for the next 12 months.

25

Income Taxes.  Our cash requirements for income taxes generally approximate the income tax provision; however, there is usually some lag in paying estimated taxes during a fiscal year due to the seasonality of our operations and because estimated income tax payments are typically based on annualizing the fiscal year’s income based on year-to-date results. There is also some lag in realizing the cash benefits from the utilization of tax credits due to the interaction of our September 30 fiscal year end and the different fiscal year ends of the entities through which we receive the tax credits. In 2007, there may be more variability in the relationship between the income tax provision and income tax payments because the tax provision calculation is materially dependent upon the estimated phase-out percentage of Section 45K tax credits (see Notes 7 and 9 to the consolidated financial statements). The calendar 2007 phase-out percentage is subject to material change because it is dependent on oil prices for all of calendar 2007, which are not predictable.

As discussed previously, cash payments for income taxes are reduced for tax deductions resulting from disqualifying dispositions of incentive stock options and from the exercise of non-qualified stock options, which amount was not material in 2007. Option exercise activity is primarily dependent on our stock price and is not predictable. Likewise, it is not possible to estimate what tax benefits may be realized from future option exercises.

Summary of Future Cash Requirements.  Significant future cash uses, in addition to operational working capital requirements, including income tax payments, are currently expected to consist primarily of capital expenditures, acquisitions and investments in joint ventures, and debt service payments on outstanding long-term debt.

Legal Matters

We have ongoing litigation and asserted claims which have been incurred during the normal course of business. Reference is made to Note 9 to the consolidated financial statements for a description of our accounting for legal costs and other information about legal matters.

Recent Accounting Pronouncements

Reference is made to Note 1 to the consolidated financial statements for a discussion of accounting pronouncements that have been recently issued which we have not yet adopted.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to financial market risks, primarily related to changes in interest rates. We do not use derivative financial instruments for speculative or trading purposes, but have entered into certain hedge transactions, primarily to limit our variable interest rate exposure. The Blue Flint joint venture also has hedges in place related to variable interest rates and commodities.

As described in more detail in Note 6 to the consolidated financial statements, our senior debt, totaling $262.5 million as of March 31, 2007, bears interest at a variable-rate. As required by the senior secured credit facility, we entered into agreements to limit our variable interest rate exposure. The agreements effectively fix the LIBOR rate at 3.71% for $150.0 million of this debt through September 8, 2007. We account for these agreements as cash flow hedges, with their fair market value reflected in the consolidated balance sheet as either other assets or other liabilities. The market value of these hedges (and various other cash flow hedges to which we are a direct or indirect party) at March 31, 2007 was not material. Total comprehensive income, considering all cash flow hedge agreements to which we are a party, was not materially different from net income for either 2006 or 2007.

Considering our current balance of variable-rate debt (reduced by the $150.0 million of senior debt that effectively has a fixed interest rate until September 8, 2007), a change in the interest rate of 1% would change our interest expense by approximately $2.0 million during the 12 months ending March 31, 2008.

ITEM 4.CONTROLS AND PROCEDURES

Disclosure Controls and Procedures — We maintain disclosure controls and procedures that are designed to ensure that information we are required to disclose in the reports that we file or submit under the Securities Exchange Act of 1934 (the “Exchange Act”), such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified by SEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), to allow timely decisions regarding required disclosure.

Our management evaluated, with the participation of our CEO and CFO, the effectiveness of our disclosure controls and procedures as of March 31, 2007, pursuant to paragraph (b) of Rules 13a-15 and 15d-15 under the Exchange Act. This

26

evaluation included a review of the controls’ objectives and design, the operation of the controls, and the effect of the controls on the information presented in this Quarterly Report. Our management, including the CEO and CFO, do not expect that disclosure controls can or will prevent or detect all errors and all fraud, if any. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Our disclosure controls and procedures are designed to provide such reasonable assurance of achieving their objectives. Also, the projection of any evaluation of the disclosure controls and procedures to future periods is subject to the risk that the disclosure controls and procedures may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on their review and evaluation, and subject to the inherent limitations described above, our CEO and CFO have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of March 31, 2007 at the above-described reasonable assurance level.

Internal Control over Financial Reporting — Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even internal controls determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. The effectiveness of our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the possibility of human error, and the risk of fraud. The projection of any evaluation of effectiveness to future periods is subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies may deteriorate. Because of these limitations, there can be no assurance that any system of internal control over financial reporting will be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.

There has been no change in our internal control over financial reporting during the quarter ended March 31, 2007 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
