AMERICAN PACIFIC CORPORATION

Notes to Condensed Consolidated Financial Statements

(Unaudited, Dollars in Thousands, Except per Share Amounts)

1. INTERIM BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Interim Basis of Presentation.  The accompanying condensed consolidated financial statements of American Pacific Corporation and its subsidiaries (collectively, the “Company”, “we”, “us”, or “our”) are unaudited, but in the opinion of management, include all adjustments, which are of a normal recurring nature, necessary to a fair statement of the results for the interim periods presented. These statements should be read in conjunction with our consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended September 30, 2012. The operating results and cash flows for the three-month period ended December 31, 2012 are not necessarily indicative of the results that will be achieved for the full fiscal year or for future periods.

Accounting Policies and Principles of Consolidation.  A description of our significant accounting policies is included in Note 1 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended September 30, 2012. Our consolidated financial statements include the accounts of American Pacific Corporation and our wholly-owned subsidiaries. All intercompany accounts have been eliminated. We report our results based on a fiscal year which ends on September 30. References to Fiscal years refer to the twelve months ended or ending September 30 of the Fiscal year referenced.

Discontinued Operations.  In May 2012, our board of directors approved and we committed to a plan to sell our Aerospace Equipment segment, which was comprised of Ampac-ISP Corp. and its wholly-owned foreign subsidiaries (“AMPAC-ISP”). We completed the sale of substantially all of the assets of AMPAC-ISP effective August 1, 2012. The divestiture is a strategic shift that allows us to place more focus on the growth and performance of our pharmaceutical-related product lines. Revenues and expenses associated with the Aerospace Equipment segment operations are presented as discontinued operations for all periods presented. (See Note 10).

Use of Estimates.  The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. Judgments and assessments of uncertainties are required in applying our accounting policies in many areas. For example, key assumptions and estimates are particularly important when determining our projected liabilities for pension benefits, useful lives for depreciable and amortizable assets, and deferred tax assets. Other areas in which significant judgment exists include, but are not limited to, costs that may be incurred in connection with environmental matters and the resolution of litigation and other contingencies. Actual results may differ from estimates on which our consolidated financial statements were prepared.

Fair Value Disclosure of Financial Instruments.  The current authoritative guidance on fair value clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value and expands disclosures about the use of fair value measurements. The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 – Significant inputs to the valuation model are unobservable.

– 5 –

1. INTERIM BASIS OF PRESENTATION AND ACCOUNTING POLICIES (Continued)

We estimate the fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their carrying values due to their short-term nature. We estimate the fair value of our variable-rate term loan as of December 31, 2012 to be approximately equal to its carrying value of $58,875 due to the close proximity of the balance sheet date to the original issuance date of the term loan.

Depreciation and Amortization Expense.  Depreciation and amortization expense, associated with our continuing operations, is classified as follows in our statements of operations:

	Three Months Ended
	December 31,
	2012		2011
Depreciation classified as:
Cost of revenues	$	3,222	$	3,272
Operating expenses		88		101
Total continuing operations		3,310		3,373
Depreciation and amortization classified as discontinued operations		-		309
Total	$	3,310	$	3,682

Bill and Hold Transactions. Some of our fine chemicals products customers have requested that we store materials purchased from us in our facilities (“Bill and Hold” arrangements). The sales value of inventory, subject to Bill and Hold arrangements, at our facilities was $18,217 and $19,346 as of December 31, 2012 and September 30, 2012, respectively.

Recently Issued or Adopted Accounting Standards.  In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, which amends Topic 220, Comprehensive Income. The amendment allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements, and eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. This standard was effective for us beginning on October 1, 2012. This standard changes presentation requirements, and accordingly, the adoption of this standard did not have an impact on our results of operations, financial position or cash flows.

2. SHARE-BASED COMPENSATION

We account for our share-based compensation arrangements under an accounting standard which requires us to measure the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The fair values of awards are recognized as additional compensation expense, which is classified as operating expenses, proportionately over the vesting period of the awards.

Our share-based compensation arrangements are designed to advance the long-term interests of the Company, including by attracting and retaining employees and directors and aligning their interests with those of our stockholders. The amount, frequency, and terms of share-based awards may vary based on competitive practices, our operating results, government regulations and availability under our equity incentive plans. Depending on the form of the share-based award, new shares of our common stock may be issued upon grant, option exercise or vesting of the award. We maintain three share-based plans, each as discussed below.

The American Pacific Corporation Amended and Restated 2001 Stock Option Plan (the “2001 Plan”) permitted the granting of stock options to employees, officers, directors and consultants.

2. SHARE-BASED COMPENSATION (Continued)

Options granted under the 2001 Plan generally vested 50% at the grant date and 50% on the one-year anniversary of the grant date, and expire ten years from the date of grant. Under the terms of the 2001 Plan, no options may be granted on or after January 16, 2011, but options previously granted, may extend beyond that date based on the terms of the relevant grant. This plan was approved by our stockholders.

The American Pacific Corporation 2002 Directors Stock Option Plan, as amended and restated (the “2002 Directors Plan”) compensates non-employee directors with stock options granted annually or upon other discretionary events. Options granted under the 2002 Directors Plan prior to September 30, 2007 generally vested 50% at the grant date and 50% on the one-year anniversary of the grant date, and expire ten years from the date of grant. Options granted under the 2002 Directors Plan in November 2007 vested 50% one year from the date of grant and 50% two years from the date of grant, and expire ten years from the date of grant. Under the terms of the 2002 Plan, no options may be granted on or after November 12, 2012, but options previously granted, may extend beyond that date based on the terms of the relevant grant. This plan was approved by our stockholders.

The American Pacific Corporation Amended and Restated 2008 Stock Incentive Plan (the “2008 Plan”) permits the granting of stock options, restricted stock, restricted stock units and stock appreciation rights to employees, directors and consultants. A total of 800,000 shares of common stock are authorized for issuance under the 2008 Plan, provided that no more than 400,000 shares of common stock may be granted pursuant to awards of restricted stock and restricted stock units. Generally, awards granted under the 2008 Plan vest in three equal annual installments beginning on the first anniversary of the grant date, and in the case of option awards, expire ten years from the date of grant. As of December 31, 2012, there were 238,483 shares available for grant under the 2008 Plan. This plan was approved by our stockholders.

Stock Options and Restricted Stock. A summary of our outstanding and non-vested stock option and restricted stock activity for the three months ended December 31, 2012 is as follows:

Weighted-average exercise price per share	$	8.60
Aggregate intrinsic value	$	3,497
Weighted-average remaining contractual term in years		5.1

– 7 –

2. SHARE-BASED COMPENSATION (Continued)

We determine the fair value of stock option awards at their grant date, using a Black-Scholes Option-Pricing model applying the assumptions in the following table. We determine the fair value of restricted stock awards based on the fair market value of our common stock on the grant date. Actual compensation, if any, ultimately realized by optionees may differ significantly from the amount estimated using an option valuation model.

	Three Months Ended
	December 31,
	2012		2011
Weighted-average grant date fair value per share of options granted	$	5.41	$	3.46

Restricted stock	$	438	$	323
Weighted-average years to be recognized
Stock options		1.8		1.8
Restricted stock		1.8		1.9

Cash-Settled Restricted Stock Units. Cash-settled restricted stock units (“RSU”) are awards that, if vested, entitle the recipient to a cash payment equal to the fair market value of our common stock for each unit granted. The RSU awards cliff-vest on September 30, 2014, subject to the attainment of financial performance criteria that were established for the two-year period ending September 30, 2014 and continued employment by the recipient. RSUs are accounted for as liability awards, and accordingly, compensation cost is re-measured based on our closing stock price at the end of each reporting period. If we estimate that it is probable that the vesting criteria will be met, then we record compensation expense based on the proportionate share of the total estimated fair value of the award to the requisite service period.

A summary of our RSU activity for the three months ended December 31, 2012 is as follows:

			Weighted-
			Average Grant
	Number of		Date Fair Value
	Units		Per Unit
Outstanding, September 30, 2012		-		-
Grants		77,231	$	11.93

5. DEBT

Our outstanding debt balances consist of the following:

	December 31,		September 30,
	2012		2012
Term Loan, variable-rate interest, due through 2017	$	58,875	$	-

Less Current Portion		(4,890)		(16)
Total Long-term Debt	$	54,001	$	65,004

Senior Notes. In February 2007, we issued and sold 9.0% Senior Notes due February 1, 2015 (the “Senior Notes”) with an initial aggregate principal amount of $110,000. The Senior Notes accrued interest at an annual rate of 9.0%, payable semi-annually in February and August. The Senior Notes were guaranteed on a senior unsecured basis by all of our existing and future material U.S. subsidiaries.

In connection with our entering into the Credit Facility (as defined below), on October 26, 2012, a notice of redemption was issued for all remaining outstanding Senior Notes specifying a redemption date of November 25, 2012. The Redemption Price for the Notes was 102.250% of the outstanding principal amount of $65,000, plus accrued and unpaid interest to, but not including, the redemption date. On October 26, 2012, we irrevocably deposited funds with the trustee in an amount equal to the Redemption Price for the Senior Notes and the related indenture was discharged. The transaction resulted in a net loss on debt retirement of $2,835 which includes the call premium of $1,463, the write-off of then unamortized debt issuances costs of $1,251 and other expenses of $121.

On January 31, 2011, American Pacific Corporation, as borrower, entered into an asset based lending credit agreement (the “ABL Credit Facility”) with Wells Fargo Bank, National Association, as agent and as lender, and certain domestic subsidiaries of the Company, as guarantors, which provided a secured revolving credit facility in an aggregate principal amount of up to $20,000 at any time outstanding with an initial maturity of 90 days prior to the maturity date of the Senior Notes, which was February 1, 2015. The maximum borrowing availability under the ABL Credit Facility was based upon a percentage of our eligible account receivables and eligible inventories. On October 26, 2012, we terminated the ABL Credit Facility.

Credit Facility. On October 26, 2012, we entered into an $85,000 senior secured credit agreement (the “Credit Facility”) by and among American Pacific Corporation, the lenders party thereto (the “Lenders”) and KeyBank National Association, as the swing line lender, issuer of letters of credit under the Credit Facility and as the Administrative Agent of the Lenders. Under the Credit Facility, we (i) obtained a term loan in the aggregate principal amount of $60,000 with an initial maturity in 5 years (the “Term Loan”), and (ii) may obtain revolving loans of up to $25,000 in aggregate principal amount, of which up to $5,000 may be outstanding in connection with the issuance of letters of credit (the “Revolving Facility”). We may prepay and terminate the Credit Facility at any time, without premium or penalty. The Credit Facility contains certain mandatory prepayment provisions which are based upon certain asset sales, equity issuances, incurrence of certain indebtedness and events of loss.

For any loans under the Credit Facility, we elect between two options to determine the annual interest rates applicable to such loans: Base Rate Loans and Eurodollar Loans. These elections can be renewed or changed from time to time during the term of the Credit Facility. The interest rate for an election period is determined as the Base Rate or the Adjusted Eurodollar Rate (each as defined in the Credit Facility), and in each case, plus an applicable margin, which shall range from 0.75% to 1.50% for Base Rate Loans or from 1.75% to 2.50% for Eurodollar Loans, subject to adjustment based on the leverage ratio. Interest payments are due at least quarterly and may be more

frequent under certain Eurodollar Loan elections. The Term Loan includes quarterly principal amortization payments which commenced on December 31, 2012. Scheduled Amortization of the Term Loan is $4,500, $6,000, $6,000, $6,000 and $7,500 for each of the five years in the period ending September 30, 2017, respectively. The remaining balance of the Term Loan of $30,000 is due upon maturity.

The Credit Facility is guaranteed by our current and future domestic subsidiaries and is secured by substantially all of our assets and the assets of our current and future domestic subsidiaries, subject to certain exceptions as set forth in the Credit Facility. The Credit Facility contains customary affirmative, negative and financial covenants which, among other things, restrict our ability to:

• pay dividends, repurchase our stock, or make other restricted payments;

• make certain investments or acquisitions;

• incur additional indebtedness;

• create or permit to exist certain liens;

• enter into certain transactions with affiliates;

• consummate a merger, consolidation or sale of assets;

• change our business; and

• wind up, liquidate, or dissolve our affairs.

In each case, the covenants set forth above are subject to customary and negotiated exceptions and exclusions.

The Credit Facility includes two financial covenants that are measured quarterly.

Leverage Ratio.  The Leverage Ratio must be less than or equal to 3.00 to 1.00. The Credit Facility defines the Leverage Ratio as the ratio of Consolidated Total Debt as of the last day of a quarter (“Test Date”) to Consolidated EBITDA for the four consecutive quarters preceding the Test Date, each as defined in the Credit Facility.

Debt Service Coverage Ratio.  The Debt Service Coverage Ratio must be at least 2.00 to 1.00, with increases to 2.25 to 1.00 for the period commencing September 30, 2014 to September 29, 2015, and to 2.50 to 1.00 for the period commencing September 30, 2015 and thereafter. The Credit Facility defines the Debt Service Coverage Ratio as the ratio of Consolidated EBITDA minus Consolidated Capital Expenditures to Scheduled Repayments plus Consolidated Adjusted Interest Expense, each as defined in the Credit Facility.

With respect to these covenant compliance calculations, Consolidated EBITDA, as defined in the Credit Facility (hereinafter, referred to as “Credit Facility EBITDA”), differs from typical EBITDA calculations and our calculation of Adjusted EBITDA, which is used in certain of our public releases and in connection with our incentive compensation plan. The most significant difference in the Credit Facility EBITDA calculation is the inclusion of cash payments for environmental remediation as part of the calculation. The following statements summarize the elements of those definitions that are material to our computations. Consolidated Total Debt generally includes principal amounts outstanding under our Credit Facility, capital leases, drawn amounts for outstanding letters of credit and other indebtedness for borrowed money. Credit Facility EBITDA is generally computed as consolidated net income (loss) plus income tax expense (benefit), interest expense, depreciation and amortization, stock-based compensation expense, and certain non-cash charges and less cash payments for environmental remediation, extraordinary gains and certain other non-cash gains. In accordance with the definitions contained in the Credit Facility, as of December 31, 2012, our Leverage Ratio was 1.34 to 1.00 and our Debt Service Coverage Ratio was 5.63 to 1.00.

The Credit Facility also contains usual and customary events of default (subject to certain threshold amounts and grace periods). If an event of default occurs and is continuing, the Company may be required to repay the obligations under the Credit Facility prior to the Credit Facility’s stated maturity and the related commitments may be terminated.

Debt Issue Costs. In connection with the issuance of the Credit Facility, we incurred debt issuance costs of approximately $1,364, which are capitalized and classified as other assets on our consolidated balance sheets. These costs are being amortized, using the effective interest rate method, as additional interest expense over the term of the Credit Facility.

Letters of Credit. As of December 31, 2012, we had $385 in outstanding standby letters of credit which mature through April 2016. These letters of credit principally secure performance of certain water treatment equipment sold by us. The letters of credit are collateralized by cash on deposit with the issuing bank in the amount of 105% of the outstanding letters of credit. Collateral deposits are classified as other assets on our consolidated balance sheets.

Regulatory Review of Perchlorates.  Our Specialty Chemicals segment manufactures and sells products that contain perchlorates. Currently, perchlorate is on Contaminant Candidate List 3 of the U.S. Environmental Protection Agency (the “EPA”). In February 2011, the EPA announced that it had determined to move forward with the development of a regulation for perchlorates in drinking water, reversing its October 2008 preliminary determination not to promulgate such a regulation. Accordingly, the EPA announced its intention to begin to evaluate the feasibility and affordability of treatment technologies to remove perchlorate and to examine the costs and benefits of potential standards. The EPA has conducted various meetings, as required by the Safe Drinking Water Act, including a meeting of the Science Advisory Board, whose report has not yet been made public. We continue to monitor activities and expect the proposed regulation to be published in February 2013 followed by a 60-day public comment period. The earliest a final regulation is expected to be published is August 2014. Regulatory review and anticipated regulatory actions present general business risk to the Company, but no regulatory proposal of the EPA or any state in which we operate, to date, has been publicly announced that we believe would have a material effect on our results of operations and financial position or that would cause us to significantly modify or curtail our business practices, including our remediation activities discussed below.

Perchlorate Remediation Project in Henderson, Nevada. We commercially manufactured perchlorate chemicals at a facility in Henderson, Nevada (the “AMPAC Henderson Site”) from 1958 until the facility was destroyed in May 1988, after which we relocated our production to a new facility in Iron County, Utah. Kerr-McGee Chemical Corporation (“KMCC”) also operated a perchlorate production facility in Henderson, Nevada (the “KMCC Site”) from 1967 to 1998. In addition, between 1956 and 1967, American Potash operated a perchlorate production facility and, for many years prior to 1956, other entities also manufactured perchlorate chemicals at the KMCC Site. As a result of a longer production history in Henderson, KMCC and its predecessor operations manufactured significantly greater amounts of perchlorate over time than we did at the AMPAC Henderson Site.

In 1997, the Southern Nevada Water Authority (“SNWA”) detected trace amounts of the perchlorate anion in Lake Mead and the Las Vegas Wash. Lake Mead is a source of drinking water for Southern Nevada and areas of Southern California. The Las Vegas Wash flows into Lake Mead from the Las Vegas valley.

In response to this discovery by SNWA, and at the request of the Nevada Division of Environmental Protection (“NDEP”), we engaged in an investigation of groundwater near the AMPAC Henderson Site and down gradient toward the Las Vegas Wash. The investigation and related characterization, which lasted more than six years, employed experts in the field of hydrogeology. This investigation concluded that although there is perchlorate in the groundwater in the vicinity of the AMPAC Henderson Site up to 700 parts per million, perchlorate from this site does

not materially impact, if at all, water flowing in the Las Vegas Wash toward Lake Mead. It has been well established, however, by data generated by SNWA and NDEP, that perchlorate from the KMCC Site did impact the Las Vegas Wash and Lake Mead. The Nevada Environmental Response Trust (“NERT”), which is the entity responsible for completing environmental remediation work at the Henderson location as a result of the 2010 settlement of the 2009 bankruptcy of KMCC’s successor, Tronox LLC, operates an above ground perchlorate groundwater remediation facility at their Henderson site. Tronox LLC is currently a tenant of NERT at the property.

Notwithstanding these facts, and at the direction of NDEP and the EPA, we conducted an investigation of remediation technologies for perchlorate in groundwater with the intention of remediating groundwater near the AMPAC Henderson Site. In 2002, we conducted a pilot test and in Fiscal 2005, we submitted a work plan to NDEP for the construction of a remediation facility near the AMPAC Henderson Site. The conditional approval of the work plan by NDEP in our third quarter of Fiscal 2005 allowed us to generate estimated costs for the installation and operation of the remediation facility to address perchlorate at the AMPAC Henderson Site. We commenced construction in July 2005. In December 2006, we began operations of the permanent facility. The location of this facility is several miles, in the direction of groundwater flow, from the AMPAC Henderson Site.

From time to time, we have held discussions with NDEP to formalize our remediation efforts in an agreement that, if executed, would provide more detailed regulatory guidance on environmental characterization and remedies at the AMPAC Henderson Site and vicinity. Typically, such agreements generally cover such matters as the scope of work plans, schedules, deliverables, remedies for non compliance, and reimbursement to the State of Nevada for past and future oversight costs. Discussions regarding a formal agreement are currently active and we anticipate that a formal agreement is likely to be completed during our Fiscal 2013.

Henderson Site Environmental Remediation Reserve.  We accrue for anticipated costs associated with environmental remediation that are probable and estimable. On a quarterly basis, we review our estimates of future costs that could be incurred for remediation activities. In some cases, only a range of reasonably possible costs can be estimated. In establishing our reserves, the most probable estimate is used; otherwise, we accrue the minimum amount of the range.

During Fiscal 2005 and Fiscal 2006, we recorded aggregate charges of $26,000 representing our estimates at the time of the probable costs of our remediation efforts at the AMPAC Henderson Site, including the costs for capital equipment and on-going operating and maintenance (“O&M”).

Late in Fiscal 2009, we gained additional information from groundwater modeling that indicates groundwater emanating from the AMPAC Henderson Site in certain areas in deeper zones (more than 150 feet below ground surface) is moving toward our existing remediation facility at a much slower pace than previously estimated. Utilization of our existing facilities alone, at this slower groundwater pace, could, according to this groundwater model, extend the life of our remediation project to well in excess of fifty years. As a result of this additional data, related model interpretations and consultations with NDEP, we re-evaluated our remediation operations and determined that we should be able to improve the effectiveness of the treatment program and significantly reduce the total project time by expanding the treatment system existing at the time. The expansion includes installation of additional groundwater extraction wells in the deeper, more concentrated areas, construction of an underground pipeline to move extracted groundwater to our treatment facility, and the addition of fluidized bed reactor (“FBR”) bioremediation treatment equipment (the “Expansion Project”) that will enhance, and in some cases replace, primary components of the existing treatment system. In our Fiscal 2009 fourth quarter, we accrued $13,700 as our initial estimate of the capital cost of the Expansion Project and the related estimates of the effects of the enhanced operations on the on-going O&M costs and project life.

– 13 –

6. COMMITMENTS AND CONTINGENCIES (Continued)

Through June 2011, and in cooperation with NDEP, we worked to develop the formal design, engineering and permitting of the Expansion Project. Based on data obtained through that date, which was largely comprised of firm quotations, we determined that significant modifications to our Fiscal 2009 assumptions were required. As a result, in June 2011, we accrued an additional $6,000 for the estimated increase in cost of the capital component of the Expansion Project, offset slightly by reductions in O&M cost estimates. The estimated capital costs of the Expansion Project increased by approximately $6,400. The increase reflected (i) an increase in the capacity of the FBR bioremediation treatment equipment to accommodate technical requirements based on the testing of new extraction wells in the fall of 2010, and (ii) higher than initially anticipated cost associated with the installation of the equipment and construction of the pipeline. Our estimate of total O&M costs was reduced by approximately $400.

In September 2012, we commenced initial operation of the Expansion Project. Related system optimization and other start-up activities will continue into Fiscal 2013. In September 2012, we recorded an additional remediation charge in the amount of $700, which is substantially attributed to the true-up of estimates to the expected final cost of the Expansion Project. Due to uncertainties inherent in making estimates, our estimates of capital and O&M costs may later require significant revision as new facts become available and circumstances change.

The estimated life of the project is a key assumption underlying the accrued estimated cost of our remediation activities. Groundwater modeling and other information regarding the characteristics of the surrounding land and demographics indicate that at our targeted processing rate of 450 gallons per minute for the new groundwater extraction wells (750 gallons per minute in the aggregate with existing wells), the life of the project could range from 5 to 18 years from the date that the Expansion Project was placed in service. Further, the data indicates that within that range, 7 to 14 years is the more likely range. In accordance with generally accepted accounting principles, if no point within the more likely range is considered more likely than another, then estimates should be based on the low end of the range. Accordingly, our accrued remediation cost includes estimated O&M costs through 2019, which is the low end of the likely range of the project life. Groundwater speed, perchlorate concentrations, aquifer characteristics and forecasted groundwater extraction rates will continue to be key factors considered when estimating the life of the project. If additional information becomes available in the future that leads to a different interpretation of the model, thereby dictating a change in equipment and operations, our estimate of the resulting project life could change significantly.

The estimate of the annual O&M cost of the project is a key assumption in our computation of the estimated cost of our remediation activities. To estimate O&M costs, we consider, among other factors, the project scope and historical expense rates to develop assumptions regarding labor, utilities, repairs, maintenance supplies and professional services costs. We estimate average annual O&M costs to be approximately $1,900. If additional information becomes available in the future that is different than information currently available to us and thereby leads us to different conclusions, our estimate of O&M expenses could change significantly.

In addition, certain remediation activities are conducted on public lands under operating permits. In general, these permits may require us to relocate our underground pipeline or equipment to accommodate future public utilities and features and require us to return the land to its original condition at the end of the permit period. If we are required to relocate our underground pipeline or equipment in the future, the costs of such activities would be incremental to our current cost estimates. Estimated costs associated with removal of remediation equipment from the land are not material and are included in our range of estimated costs.

As of December 31, 2012, the aggregate range of anticipated environmental remediation costs was from approximately $10,900 to approximately $34,800. This range represents a significant estimate and is based on the estimable elements of cost for capital and O&M costs, and an estimated remaining operating life of the project

– 14 –

through a range from the years 2017 to 2030. As of December 31, 2012, the accrued amount was $14,666, based on an estimated remaining life of the project through the year 2019, or the low end of the more likely range of the expected life of the project. Cost estimates are based on our current assessments of the facility configuration. As we proceed with the project, we have, and may in the future, become aware of elements of the facility configuration that must be changed to meet the targeted operational requirements. Certain of these changes may result in corresponding cost increases. Costs associated with the changes are accrued when a reasonable alternative, or range of alternatives, is identified and the cost of such alternative is estimable. Our estimated reserve for environmental remediation is based on information currently available to us and may be subject to material adjustment upward or downward in future periods as new facts or circumstances may indicate.

A summary of our environmental reserve activity for the three months ended December 31, 2012 is shown below:

Balance, September 30, 2012	$	16,754
Expenditures		(2,088)
Balance, December 31, 2012	$	14,666

AFC Environmental Matters.  The primary operations of our Fine Chemicals segment are located on land leased from Aerojet-General Corporation (“Aerojet”), a wholly-owned subsidiary of GenCorp Inc. (“GenCorp”). The leased land is part of a tract of land owned by Aerojet designated as a “Superfund site” under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (“CERCLA”). The tract of land had been used by Aerojet and affiliated companies to manufacture and test rockets and related equipment since the 1950s. Although the chemicals identified as contaminants on the leased land were not used by Aerojet Fine Chemicals LLC (predecessor in interest to Ampac Fine Chemicals LLC) as part of its operations, CERCLA, among other things, provides for joint and several liability for environmental liabilities including, for example, environmental remediation expenses.

As part of the agreement by which we acquired our Fine Chemicals segment business from GenCorp, an Environmental Indemnity Agreement was entered into whereby GenCorp agreed to indemnify us against any and all environmental costs and liabilities arising out of or resulting from any violation of environmental law prior to the effective date of the sale, or any release of hazardous substances by Aerojet Fine Chemicals LLC, Aerojet or GenCorp on the premises of Ampac Fine Chemicals LLC or Aerojet’s Sacramento site prior to the effective date of the sale.

On November 29, 2005, EPA Region IX provided us with a letter indicating that the EPA does not intend to pursue any clean up or enforcement actions under CERCLA against future lessees of the Aerojet property for existing contamination, provided that the lessees do not contribute to or do not exacerbate existing contamination on or under the Aerojet Superfund site.

Other Matters.  Although we are not currently party to any material pending legal proceedings, we are from time to time subject to claims and lawsuits related to our business operations. We accrue for loss contingencies when a loss is probable and the amount can be reasonably estimated. Legal fees, which can be material in any given period, are expensed as incurred. We believe that current claims or lawsuits against us, individually and in the aggregate, will not result in loss contingencies that will have a material adverse effect on our financial condition, cash flows or results of operations.

7. SEGMENT INFORMATION

We report our continuing operations in three operating segments: Fine Chemicals, Specialty Chemicals, and Other Businesses. These segments are based upon business units that offer distinct products and services, are operationally managed separately and produce products using different production methods. Segment operating income or loss includes all sales and expenses directly associated with each segment. Environmental remediation charges, corporate general and administrative costs, which consist primarily of executive, investor relations, accounting, human resources and information technology expenses, and interest are not allocated to segment operating results.

Fine Chemicals. Our Fine Chemicals segment includes the operating results of our wholly-owned subsidiaries Ampac Fine Chemicals LLC and AMPAC Fine Chemicals Texas, LLC (collectively, “AFC”). AFC is a custom manufacturer of active pharmaceutical ingredients and registered intermediates for commercial customers in the pharmaceutical industry. AFC operates in compliance with the U.S. Food and Drug Administration’s current Good Manufacturing Practices and the requirements of certain other regulatory agencies such as the European Union’s European Medicines Agency and Japan’s Pharmaceuticals and Medical Devices Agency. AFC also complies with Drug Enforcement Administration requirements related to the manufacture and sale of certain controlled substances. AFC has distinctive competencies and specialized engineering capabilities in performing chiral separations, manufacturing chemical compounds that require high containment, performing energetic chemistries at commercial scale, and manufacturing Schedule II controlled substances.

Specialty Chemicals. Our Specialty Chemicals segment manufactures and sells: (i) perchlorate chemicals, principally ammonium perchlorate, which is the predominant oxidizing agent for solid propellant rockets, booster motors and missiles used in space exploration, commercial satellite transportation and national defense programs, (ii) sodium azide, a chemical used in pharmaceutical manufacturing, and (iii) Halotron^®, a series of clean fire extinguishing agents used in fire extinguishing products ranging from portable fire extinguishers to total flooding systems.

Other Businesses. Our Other Businesses segment contains our water treatment equipment division and real estate activities. Our water treatment equipment business markets, designs, and manufactures electrochemical On Site Hypochlorite Generation, or OSHG, systems. These systems are used in the disinfection of drinking water, control of noxious odors, and the treatment of seawater to prevent the growth of marine organisms in cooling systems. We supply our equipment to municipal, industrial and offshore customers. Our real estate activities are not material.

Our revenues are characterized by individually significant orders and relatively few customers. As a result, in any given reporting period, certain customers may account for more than ten percent of our consolidated revenues. The following table provides disclosure of the percentage of our consolidated revenues from continuing operations attributed to customers that exceed ten percent of the total in each of the given periods.

8. INCOME TAXES

We review our portfolio of uncertain tax positions and recorded liabilities based on the applicable recognition standards. In this regard, an uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. We classify uncertain tax positions as non-current income tax liabilities unless expected to be settled within one year.

As of both December 31, 2012 and September 30, 2012, our recorded liability for unrecognized tax benefits was $204 and $1,274, of which $204 and $405 would affect our effective tax rate if recognized. In December 2012, the internal revenue service completed its examination of our federal income tax returns for Fiscal years 2009 and 2010 and the related net operating loss carryback claims to Fiscal years 2002, 2003, 2005, 2006, 2007 and 2008 with no significant adjustments. Upon completion of this audit, we released $1,070 of unrecognized tax benefits.

We have no additional significant statutes of limitations that are anticipated to expire in Fiscal 2013. Accordingly, it is reasonably possible that none of the gross liability for unrecognized tax benefits will be reversed during Fiscal 2013.

Unrecognized Tax Benefits - September 30, 2012	$	1,274
Additions for tax positions of prior years		-
Reductions for tax positions of prior years		(1,070)
Lapse of statute of limitations		-
Unrecognized Tax Benefits - December 31, 2012	$	204

We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2012 and September 30, 2012, we had accrued $7 and $679, respectively, for the payment of tax-related interest and penalties. For the three months ended December 31, 2012 and 2011, income tax expense (benefit) includes a benefit of $671 and an expense of $13, respectively, for interest and penalties.

– 17 –

8. INCOME TAXES (continued)

We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, we are no longer subject to federal and state examinations before Fiscal 2008.

9. DEFINED BENEFIT PLANS

Defined Benefit Plan Descriptions.  We maintain three defined benefit pension plans which cover substantially all of our employees who were employed by the Company prior to July 1, 2010: the Amended and Restated American Pacific Corporation Defined Benefit Pension Plan, the Ampac Fine Chemicals LLC Pension Plan for Salaried Employees, and the Ampac Fine Chemicals LLC Pension Plan for Bargaining Unit Employees, each as amended to date. Collectively, these three plans are referred to as the “Pension Plans”. Pension Plan benefits are paid based on an average of earnings, retirement age, and length of service, among other factors. In May 2010, our board of directors approved amendments to our Pension Plans which effectively closed the Pension Plans to participation by any new employees. Retirement benefits for existing U.S. employees and retirees through June 30, 2010 were not affected by this change. Beginning July 1, 2010, new employees began participating solely in one of the Company’s 401(k) plans. In addition, we maintain the American Pacific Corporation Supplemental Executive Retirement Plan, as amended and restated, (the “SERP”) that includes three executive officers and two former executive officers. We use a measurement date of September 30 to account for our Pension Plans and SERP.

Net periodic pension cost consists of the following:

	Three Months Ended

Recognized Actuarial Losses		94		-
Amortization of Prior Service Costs		105		105
Net Periodic Pension Cost	$	509	$	308

Defined Contribution Plan Descriptions. We maintain two 401(k) plans in which participating employees may make contributions. One covers substantially all employees except bargaining unit employees of our Fine Chemicals segment and the other covers those bargaining unit employees. We make matching contributions for all Fine Chemicals segment employees and, since July 1, 2010, for all eligible new employees.

Contributions and Benefit Payments. For the three months ended December 31, 2012, we contributed $2,391 to the Pension Plans to fund benefit payments and anticipate making approximately $4,313 in additional contributions through September 30, 2013. For the three months ended December 31, 2012, we contributed $132 to the SERP to fund benefit payments and anticipate making approximately $396 in additional contributions through September 30, 2013.

10. DISCONTINUED OPERATIONS

In May 2012, our board of directors approved and we committed to a plan to sell our Aerospace Equipment segment, which was comprised of Ampac-ISP Corp. and its wholly-owned foreign subsidiaries (“AMPAC-ISP”). The divestiture is a strategic shift that allows us to place more focus on the growth and performance of our pharmaceutical-related product lines.

On June 4, 2012, we entered into an Asset Purchase Agreement with Moog Inc. (“Moog”) (the “Asset Purchase Agreement”), pursuant to which we sold to Moog substantially all of the assets of Ampac-ISP Corp., including all of the equity interests in its foreign subsidiaries (collectively, the “Purchased Assets”). Additionally, Moog assumed certain liabilities related to the operations and the Purchased Assets. The transaction was completed effective August 1, 2012.

Under the terms of the Asset Purchase Agreement, the total consideration was approximately $46,000 (the “Purchase Price”) in cash. In addition, $4,000 of the Purchase Price (the “Escrow Amount”) will be held in an escrow account for 15 months following the closing of the transaction (the “Escrow Period”) and applied towards our indemnification obligations in favor of Moog, if any. The Asset Purchase Agreement provides that we, subject to certain limitations, indemnify Moog for damages and losses incurred or suffered by Moog as a result of, among other things, breaches of our respective representations, warranties and covenants contained in the Asset Purchase Agreement as well as any of the liabilities that we retained. The balance of the Escrow Amount remaining at the end of the Escrow Period shall be released to us. We have accounted for the Escrow Amount as a contingent gain, and accordingly have deferred recognition of the amount until all contingencies have lapsed or been resolved.

Revenues and expenses associated with the operations of AMPAC-ISP are presented as discontinued operations for all periods presented. Summarized financial information for AMPAC-ISP is as follows:

11. SUBSEQUENT EVENT

On January 24, 2013, we entered into a floating-to-fixed interest rate swap with an initial notional amount of $58,875 (such notional amount reducing over the life of the arrangement), terminating October 26, 2017, which will effectively convert our floating-rate debt to a fixed rate. Under the terms of the swap, we will pay a fixed rate of approximately 0.775% and we will receive a floating-rate payment tied to the one-month LIBOR. We designated this interest rate swap as a cash flow hedge in accordance with the accounting guidance in ASC Topic 815.

OUR COMPANY

American Pacific Corporation and its predecessors have been engaged in chemical manufacturing since 1955. We are a leading custom manufacturer of fine chemicals and specialty chemicals within our focused markets. Through our Fine Chemicals segment, we supply active pharmaceutical ingredients (“APIs”) and registered intermediates to the pharmaceutical industry. Our Specialty Chemicals segment produces various perchlorate chemicals and is the only North American producer of Ammonium Perchlorate (“AP”), which is the predominant oxidizing agent for solid propellant rockets, booster motors and missiles used in space exploration, commercial satellite transportation and national defense programs. We produce clean agent chemicals for the fire protection industry, as well as electro-chemical equipment for the water treatment industry. Our products are designed to meet customer specifications and often must meet certain governmental and regulatory approvals. Our technical and manufacturing expertise and customer service focus has gained us a reputation for quality, reliability, technical performance and innovation. Given the mission critical nature of our products, we maintain long-standing strategic customer relationships and generally sell our products through long-term contracts under which we are the sole-source or limited-source supplier.

OUR BUSINESS SEGMENTS

Our continuing operations comprise three reportable business segments: Fine Chemicals, Specialty Chemicals, and Other Businesses. The following table reflects the revenue contribution percentage from our business segments and their major product lines:

FINE CHEMICALS. Our Fine Chemicals segment, operated through our wholly-owned subsidiaries Ampac Fine Chemicals LLC and AMPAC Fine Chemicals Texas, LLC (collectively “AFC”), is a custom manufacturer of APIs and registered intermediates for customers in the pharmaceutical industry. The pharmaceutical ingredients we manufacture are used by our customers in drugs with indications in three primary areas: anti-viral, oncology, and central nervous system. AFC’s customers include some of the world’s largest pharmaceutical and biotechnology companies, as well as emerging pharmaceutical companies. Most of the products that AFC sells are proprietary to our customers and used in existing drugs that are approved by the U.S. Food and Drug Administration (“FDA”) and commercially available. We operate in compliance with the FDA’s current Good Manufacturing Practices (“cGMP”) and the requirements of certain other regulatory agencies such as the European Union’s European Medicines Agency and Japan’s Pharmaceuticals and Medical Devices Agency. Our Fine Chemicals segment’s strategy is to focus on high growth markets where our technological position, combined with our chemical process development and engineering expertise, lead to strong customer allegiances and limited competition. We have distinctive competencies and specialized engineering capabilities

– 21 –

in performing chiral separations, manufacturing products that require high containment and performing energetic chemistries at commercial scale. We have recently expanded our technology offerings to include commercial scale production of Schedule II to V controlled substances in our high-security facilities in Rancho Cordova, California.

We have invested significant resources in our facilities, workforce and technology base. We believe we are the U.S. leader in performing chiral separations using Simulated Moving Bed (“SMB”) technology and own and operate two large-scale SMB systems, both of which are among the largest in the world operating under cGMP. We offer a full range of SMB equipment and related services from laboratory-scale to our large systems. We believe our distinctive competency in manufacturing chemical compounds that require specialized high containment facilities and handling expertise provide us a significant competitive advantage in competing for various opportunities associated with high potency, highly toxic and cytotoxic products. Many oncology drugs are made with APIs that are high potency or cytotoxic. AFC is one of the few companies in the world that can manufacture such compounds at a multi-ton annual rate. Moreover, our significant experience and highly engineered facilities make us one of the few companies in the world with the capability to use energetic chemistry on a commercial-scale under cGMP. We use this capability in development and production of products such as those used in anti-viral drugs, including HIV-related and influenza-combating drugs.

We have established long-term, and in some cases sole-source, contracts with customers that represent the majority of our revenues. Contracts that are not sole-source are limited-source considering the nature of our industry and the products that we manufacture. The inherent nature of custom pharmaceutical fine chemicals manufacturing encourages stable, long-term customer relationships. We work collaboratively with our customers to develop reliable, safe and cost-effective, custom solutions. Once a custom manufacturer has been qualified as a supplier on a cGMP product, there are several potential barriers that discourage transferring the manufacturing of the product to an alternative supplier. For example, applications to and approvals from the FDA and other regulatory authorities generally require the chemical contractor to be named. Switching contractors may require additional regulatory approvals and could take as long as two years to complete. Switching contractors and amending various filings can result in significant costs associated with technology transfer, process validation and re-filing with the FDA and other regulatory authorities around the world.

SPECIALTY CHEMICALS. Our Specialty Chemicals segment is principally engaged in the production of perchlorates, which include several grades of ammonium perchlorate (“AP”), sodium perchlorate and potassium perchlorate. AP is the predominant oxidizing agent for solid propellant rockets, booster motors and missiles used in national defense, space exploration and commercial satellite transportation programs. We have supplied rocket-grade AP for use in space and defense programs for over 50 years and we have been the only rocket-grade AP supplier in North America since 1998, when we acquired the AP business of our principal competitor, Kerr-McGee Chemical Corporation. AP is a key component of solid propellant rockets, booster motors and missiles that are utilized in U.S. Department of Defense (“DOD”) tactical and strategic missile programs, as well as various space programs such as the Delta and Atlas families of commercial space launch vehicles and space exploration programs for the National Aeronautics and Space Administration (“NASA”). There is currently no domestic alternative to these solid rocket motors. As a result, we believe that the U.S. government views us as a strategic national asset.

Alliant Techsystems Inc. or “ATK” is a significant AP customer. We sell rocket-grade AP to ATK under a long-term contract that requires us to maintain a ready and qualified capacity for rocket-grade AP and that requires ATK to purchase its rocket-grade AP requirements from us, subject to certain terms and conditions. The contract, which expires in 2013, provides fixed pricing in the form of a price volume matrix for annual rocket-grade AP volumes ranging from 3 million to 20 million pounds. Pricing varies inversely to volume and includes annual escalations.

In addition, we produce and sell sodium azide, a chemical primarily used in pharmaceutical manufacturing, and Halotron^®, a series of clean fire extinguishing agents used in fire extinguishing products ranging from portable fire extinguishers to total flooding systems.

– 22 –

OTHER BUSINESSES.  Our Other Businesses segment contains our water treatment equipment division and real estate activities. Our water treatment equipment business markets, designs, and manufactures electrochemical On Site Hypochlorite Generation, or OSHG systems. These systems are used in the disinfection of drinking water, control of noxious odors, and the treatment of seawater to prevent the growth of marine organisms in cooling systems. We supply our equipment to municipal, industrial and offshore customers. Our real estate activities are not material.

DISCONTINUED OPERATIONS.  In May 2012, our board of directors approved and we committed to a plan to sell our Aerospace Equipment segment, which was comprised of Ampac-ISP Corp. and its wholly-owned foreign subsidiaries (“AMPAC-ISP”). We completed the sale of substantially all of the assets of AMPAC-ISP effective August 1, 2012. The divestiture is a strategic shift that allows us to place more focus on the growth and performance of our pharmaceutical-related product lines. Revenues and expenses associated with the operations of AMPAC-ISP are presented as discontinued operations for all periods presented.

CONSOLIDATED RESULTS OF OPERATIONS

REVENUES

For our Fiscal 2013 first quarter, revenues decreased 6% to $36,318 as compared to $38,485 for the Fiscal 2012 first quarter. The decrease is attributable to our Other Businesses segment. See further discussion below under the heading “Business Segment Results”.

INTEREST AND LOSS ON DEBT EXTINGUISHMENT

	December 31,				Increase		Percentage
	2012		2011		(Decrease)		Change
Three Months Ended:
Interest and Other Income. Net	$	8	$	7	$	1		14%
Interest Expense		1,282		2,639		(1,357)		(51%)
Loss on Debt Extinguishment		2,835		-		2,835		-

Interest expense decreased 51% in the Fiscal 2013 first quarter compared to the Fiscal 2012 first quarter, reflecting both a decrease in the average outstanding principal balance on our long term debt and a reduction in the effective interest rate that resulted from the refinancing of our long-term debt. See further discussion below under the heading “Long-Term Debt and Credit Facilities”.

In connection with our entering into the Credit Facility (as defined below), on October 26, 2012, a notice of redemption was issued for all remaining outstanding Senior Notes specifying a redemption date of November 25, 2012. The Redemption Price for the Notes was 102.250% of the outstanding principal amount of $65,000, plus accrued and unpaid interest to, but not including, the redemption date. On October 26, 2012, we irrevocably deposited funds with the trustee in an amount equal to the Redemption Price for the Senior Notes and the related indenture was discharged. The transaction resulted in a net loss on debt retirement of $2,835 which includes the call premium of $1,463, the write-off of then unamortized debt issuances costs of $1,251 and other expenses of $121.

DISCONTINUED OPERATIONS

In May 2012, our board of directors approved and we committed to a plan to sell our Aerospace Equipment segment, which was comprised of Ampac-ISP Corp. and its wholly-owned foreign subsidiaries (“AMPAC-ISP”). The divestiture is a strategic shift that allows us to place more focus on the growth and performance of our pharmaceutical-related product lines.

On June 4, 2012, we entered into an Asset Purchase Agreement with Moog Inc. (“Moog”) (the “Asset Purchase Agreement”), pursuant to which we sold to Moog substantially all of the assets of Ampac-ISP Corp., including all of the equity interests in its foreign subsidiaries (collectively, the “Purchased Assets”). Additionally, Moog assumed certain liabilities related to the operations and the Purchased Assets. The transaction was completed effective August 1, 2012.

Under the terms of the Asset Purchase Agreement, the total consideration was approximately $46,000 (the “Purchase Price”) in cash. In addition, $4,000 of the Purchase Price (the “Escrow Amount”) will be held in an escrow account for 15 months following the closing of the transaction (the “Escrow Period”) and applied towards our indemnification obligations in favor of Moog, if any. The Asset Purchase Agreement provides that we, subject to certain limitations, indemnify Moog for damages and losses incurred or suffered by Moog as a result of, among other things, breaches of our respective representations, warranties and covenants contained in the Asset Purchase Agreement as well as any of the liabilities that we retained. The balance of the Escrow Amount remaining at the end of the Escrow Period shall be released to us. We have accounted for the Escrow Amount as a contingent gain, and accordingly have deferred recognition of the amount until all contingencies have lapsed or been resolved.

Revenues	$	21,347	$	21,475
Operating Income (Loss)	$	1,277	$	(1,187)
Operating Margin		6%		(6%)

Revenues.  Fine Chemicals segment revenues for the Fiscal 2013 first quarter were consistent with the Fiscal 2012 first quarter. The timing of product orders and the related production schedule resulted in offsetting variances among our primary product categories. For the Fiscal 2013 first quarter, oncology product revenues increased 126% and development product revenues increased 46%, offset by a decrease in anti-viral products revenues of 20% and a decrease in central nervous system products revenues of 47%, each as compared to the Fiscal 2012 first quarter.

Operating Income (Loss).  The Fine Chemicals segment reported operating income of $1,277 for the Fiscal 2013 first quarter compared to an operating loss of $1,187 for the Fiscal 2012 first quarter. Fine Chemicals segment gross margin improved by 14 percentage points in the Fiscal 2013 first quarter as compared to the Fiscal 2012 first quarter. Our Fine Chemicals segment has dedicated significant efforts over the last two fiscal years to improving the efficiency of its manufacturing activities. Redesigned key processes continued to yield targeted throughput ranges during the Fiscal 2013 first quarter. In contrast, during the Fiscal 2012 first quarter, the Fine Chemicals segment had not yet achieved the benefits of these process improvements which reduced gross margin levels.

Improvements in gross profit for the Fiscal 2013 first quarter were offset by increases in general and administrative expenses of approximately $500, which includes increases in research and development costs of approximately $200 and pension related expense of approximately $100.

– 25 –

Backlog. Agreements with our Fine Chemicals segment customers typically include multi-year supply agreements. These agreements may contain provisional order volumes, minimum order quantities, take-or-pay provisions, termination fees and other customary terms and conditions, which we do not include in our computation of backlog. Fine Chemicals segment backlog includes unfulfilled firm purchase orders received from a customer, including both purchase orders which are issued against a related supply agreement and stand-alone purchase orders. Fine Chemicals segment backlog was $91,400 and $80,500 as of December 31, 2012 and September 30, 2012, respectively. We anticipate order backlog as of December 31, 2012 to be substantially filled within the next twelve months.

SPECIALTY CHEMICALS SEGMENT

Revenues	$	14,350	$	14,220
Operating Income	$	7,917	$	7,644
Operating Margin		55%		54%

Revenues. Specialty Chemicals segment revenues include revenues from our perchlorate, sodium azide and Halotron product lines, with perchlorates comprising 88% and 87% of Specialty Chemicals revenues in the Fiscal 2013 and 2012 first quarters, respectively.

Specialty Chemicals segment revenues of $14,350 for the Fiscal 2013 first quarter reflect a 1% increase as compared to the Fiscal 2012 first quarter. In addition, revenues from each of the three primary product lines were consistent when comparing the Fiscal 2013 first quarter to the Fiscal 2012 first quarter. Specific to the perchlorates product line, the consistent revenues reflect two offsetting factors. Total perchlorate volume decreased by 24%, while the related average price per pound increased by 35%. The first quarter of Fiscal 2013 included less volume for our non rocket-grade perchlorate products. This reduction in volume, which is due to inter-quarter timing, has the corresponding effect of increasing the average price per pound. Volumes and average price per pound for rocket-grade perchlorates were consistent between the Fiscal 2013 and 2012 first quarters, supported by demand from tactical missile programs in each quarter.

Operating Income. Specialty Chemicals segment operating income of $7,917 for the Fiscal 2013 first quarter reflects a 4% increase as compared to the Fiscal 2012 first quarter. Operating margin for the Fiscal 2013 first quarter improved to 55% compared to 54% for the Fiscal 2012 first quarter, primarily due to slightly improved absorption of fixed manufacturing overhead costs in the Fiscal 2013 first quarter.

Backlog. Specialty Chemicals segment backlog includes unfulfilled firm purchase orders received from a customer, including both purchase orders which are issued against long-term supply agreements and stand-alone purchase orders. Specialty Chemicals segment backlog was $42,400 and $25,100 as of December 31, 2012 and September 30, 2012, respectively. We anticipate order backlog as of December 31, 2012 to be substantially filled within the next twelve months. Specialty Chemicals product orders are typically characterized by individually large orders which occur at various times during the fiscal year. This usually results in a backlog and revenue pattern which can vary significantly from quarter to quarter.

Other Businesses segment revenues include PEPCON Systems’ water treatment equipment and related spare parts sales and real estate revenues. For the Fiscal 2013 first quarter, revenues decreased by $2,169 compared to the Fiscal 2012 first quarter due to the inter-quarter timing of equipment shipments and related sales. The Fiscal 2012 first quarter included two water-treatment systems, while none were included in the Fiscal 2013 first quarter. The operating loss increased in the Fiscal 2013 first quarter due to the lower volume when compared to the prior fiscal year first quarter.

Operating Cash Flows. Operating activities used cash of $3,272 for the Fiscal 2013 first quarter compared to a use of cash of $11,270 for the prior fiscal year first quarter, an improvement of $7,998.

Significant components of the change in cash flow from operating activities include:

• An increase in cash due to the improvement in cash profits provided by our operations.

• A decrease in cash used by working capital accounts of approximately $11,000, excluding the effects of interest and income taxes.

• An increase in cash paid for income taxes of approximately $2,300.

• An increase in cash paid for interest expense of $2,000.

• An increase in cash paid for costs associated with the retirement of long-term debt of $1,600.

• An increase in cash used for environmental remediation of approximately $1,600.

• A decrease in cash used to fund pension obligations of approximately $4,200.

• A decrease in cash provided by discontinued operations of approximately $1,000.

• Other increases in cash used by operating activities of approximately $200.

The change in working capital cash flow is primarily due to the timing of accounts receivable balances for our Specialty Chemicals segment. For the Fiscal 2013 first quarter, a substantial portion of the Specialty Chemicals revenues occurred early in the quarter and were also collected in the same quarter. This compares to the Fiscal 2012 first quarter when a substantial portion of Specialty Chemicals revenues occurred late in the quarter and were collected in the subsequent quarter.

– 27 –

Cash paid for income taxes increased because our federal operating loss carryforwards were fully utilized in Fiscal 2012. Accordingly, we expect to pay cash taxes in Fiscal 2013.

Interest expense for the Fiscal 2013 first quarter decreased due to lower outstanding debt and lower interest rates. However, the cash paid for interest in the Fiscal 2013 first quarter increased due to a change in the timing of our interest payments. During Fiscal 2012, our interest payments were due semi-annually in February and August. For Fiscal 2013, interest payments under our new Credit Facility (discussed below) are due at least quarterly. In addition, in connection with the retirement of our senior notes in October 2012, we paid all accrued interest through the redemption date. In October 2012, we also incurred cash redemption costs of approximately $1,600 comprised primarily of the call premium to redeem the senior notes. See further discussion below under the heading “Long-Term Debt and Credit Facilities”.

During our Fiscal 2013 first quarter we spent approximately $2,100 for remediation activities compared to approximately $500 in Fiscal 2012 first quarter. The increase reflects cash used for the capital elements of the Henderson, Nevada expansion project.

We make payments to fund defined benefit pension obligations at a level of at least 80% of the obligation. Our contributions were reduced in the Fiscal 2013 first quarter, as compared to the Fiscal 2012 first quarter, primarily due to improved plan asset returns in Fiscal 2012. In Fiscal 2012, we made additional contributions to our pension plans because the return on pension plan assets in the preceding year was not sufficient to maintain our target funding requirements.

Investing Cash Flows. Capital expenditures in the Fiscal 2013 first quarter were $1,961 compared to $1,099 for the prior fiscal year first quarter. The increase is due to the timing of Fine Chemicals segment maintenance-capital projects which were more heavily weighted to the first quarter in Fiscal 2013 as compared to Fiscal 2012.

Financing Cash Flows.  For our Fiscal 2013 first quarter, financing activities used cash of $7,174 compared to a use of cash of $20 for the prior fiscal year first quarter. The Fiscal 2013 first quarter amount includes a reduction in our long-term debt of $5,000 and debt issuance costs of approximately $1,400, each incurred in connection with our October 2012 refinancing activities. See further discussion below under the heading “Long-Term Debt and Credit Facilities”.

LIQUIDITY AND CAPITAL RESOURCES. As of December 31, 2012, we had cash of $18,775 and no borrowing outstanding against our revolving credit facility. Our primary source of working capital is cash flows from operations and our revolving credit facility.

In October 2012, we called and terminated our senior notes with an aggregate principal amount of $65,000 and replaced the notes with a credit facility that includes a $60,000 term loan and a $25,000 revolving credit line. Funds used to call the notes of $68,315, were provided by the net proceeds from the term loan and available cash balances. The revolving credit line provides a committed revolving credit line, up to a maximum of $25,000. For further discussion, see below under the heading “Long-Term Debt and Credit Facilities”. The term loan requires quarterly principal and interest payments, which differs from the senior notes which had no principal amortization requirements. We do not anticipate that the principal payment requirements under the new facility will have a significant impact on our liquidity because we expect that the cash requirements for principal payments will be substantially offset by lower interest expense.

We believe that changes in cash flow from operations during our fiscal periods reflect short-term timing and accordingly, do not represent significant changes in our sources and uses of cash. Because our revenues, and related customer invoices and collections, are characterized by relatively few individually significant transactions, our working capital balances can vary normally by as much as $10,000 from period to period.

– 28 –

We may incur additional debt to fund capital projects, strategic initiatives or for other general corporate purposes, subject to our existing leverage, the value of our unencumbered assets and borrowing limitations imposed by our lenders. The availability of our cash inflows is affected by the timing, pricing and magnitude of orders for our products. From time to time, we may explore options to refinance our borrowings.

The timing of our cash outflows is affected by payments and expenses related to the manufacture of our products, capital projects, pension funding, interest on our debt obligations and environmental remediation or other contingencies, which may place demands on our short-term liquidity. Although we are not currently party to any material pending legal proceedings, we are from time to time subject to claims and lawsuits related to our business operations and we have incurred legal and other costs as a result of litigation and other contingencies. We may incur material legal and other costs associated with the resolution of litigation and contingencies in future periods, and, to the extent not covered by insurance, they may adversely affect our liquidity.

In contemplating the adequacy of our liquidity and available capital, we consider factors such as:

• current results of operations, cash flows and backlog;

• anticipated changes in operating trends, including anticipated changes in revenues and margins;

• cash requirements related to our debt agreements and pension plans; and

• cash requirements related to our remediation activities.

We do not currently anticipate that the factors noted above will have material effects on our ability to meet our future liquidity requirements. We continue to believe that our cash flows from operations, existing cash balances and existing or future debt arrangements will be adequate for the foreseeable future to satisfy the needs of our operations on both a short-term and long-term basis.

LONG-TERM DEBT AND CREDIT FACILITIES

Senior Notes. In February 2007, we issued and sold $110,000 aggregate principal amount of 9.0% Senior Notes due February 1, 2015 (the “Senior Notes”). The Senior Notes accrued interest at an annual rate of 9.0%, payable semi-annually in February and August. The Senior Notes were guaranteed on a senior unsecured basis by all of our existing and future material U.S. subsidiaries.

In connection with our entering into the Credit Facility (as defined below), on October 26, 2012, a notice of redemption was issued for all remaining outstanding Senior Notes specifying a redemption date of November 25, 2012. The Redemption Price for the Notes was 102.250% of the outstanding principal amount of $65,000, plus accrued and unpaid interest to, but not including, the redemption date. On October 26, 2012, we irrevocably deposited funds with the trustee in an amount equal to the Redemption Price for the Senior Notes and the related indenture was discharged. The transaction resulted in a net loss on debt retirement of $2,835, which includes the call premium of $1,463, the write-off of then unamortized debt issuances costs of $1,251 and other expenses of $121.

ABL Credit Facility. On January 31, 2011, American Pacific Corporation, as borrower, entered into an asset based lending credit agreement (the “ABL Credit Facility”) with Wells Fargo Bank, National Association, as agent and as lender, and certain domestic subsidiaries of the Company, as guarantors, which provided a secured revolving credit facility in an aggregate principal amount of up to $20,000 at any time outstanding with an initial maturity of 90 days prior to the maturity date of the Senior Notes, which was February 1, 2015. The maximum borrowing availability under the ABL Credit Facility was based upon a percentage of our eligible account receivables and eligible inventories. On October 26, 2012, we terminated the ABL Credit Facility.

Credit Facility. On October 26, 2012, we entered into an $85,000 senior secured credit agreement (the “Credit Facility”) by and among American Pacific Corporation, the lenders party thereto (the “Lenders”) and KeyBank National Association, as the swing line lender, issuer of letters of credit under the Credit Facility and as the Administrative Agent of the Lenders. Under the Credit Facility, we (i) obtained a term loan in the aggregate principal amount of $60,000 with an initial maturity in 5 years (the “Term Loan”), and (ii) may obtain revolving loans of up to $25,000 in aggregate principal amount, of which up to $5,000 may be outstanding in connection with the issuance of letters of credit (the “Revolving Facility”). We may prepay and terminate the Credit Facility at any time, without premium or penalty. The Credit Facility contains certain mandatory prepayment provisions which are based upon certain asset sales, equity issuances, incurrence of certain indebtedness and events of loss.

For any loans under the Credit Facility, we elect between two options to determine the annual interest rates applicable to such loans: Base Rate Loans and Eurodollar Loans. These elections can be renewed or changed from time to time during the term of the Credit Facility. The interest rate for an election period is determined as the Base Rate or the Adjusted Eurodollar Rate (each as defined in the Credit Facility), and in each case, plus an applicable margin, which shall range from 0.75% to 1.50% for Base Rate Loans or from 1.75% to 2.50% for Eurodollar Loans, subject to adjustment based on the leverage ratio. Interest payments are due at least quarterly and may be more frequent under certain Eurodollar Loan elections. The Term Loan includes quarterly principal amortization payments which commenced on December 31, 2012. Scheduled Amortization of the Term Loan is $4,500, $6,000, $6,000, $6,000 and $7,500 for each of the five years in the period ending September 30, 2017, respectively. The remaining balance of the Term Loan of $30,000 is due upon maturity.

The Credit Facility is guaranteed by our current and future domestic subsidiaries and is secured by substantially all of our assets and the assets of our current and future domestic subsidiaries, subject to certain exceptions as set forth in the Credit Facility. The Credit Facility contains customary affirmative, negative and financial covenants which, among other things, restrict our ability to:

• pay dividends, repurchase our stock, or make other restricted payments;

• make certain investments or acquisitions;

• incur additional indebtedness;

• create or permit to exist certain liens;

• enter into certain transactions with affiliates;

• consummate a merger, consolidation or sale of assets;

• change our business; and

• wind up, liquidate, or dissolve our affairs.

In each case, the covenants set forth above are subject to customary and negotiated exceptions and exclusions.

The Credit Facility includes two financial covenants that are measured quarterly.

Leverage Ratio.  The Leverage Ratio must be less than or equal to 3.00 to 1.00. The Credit Facility defines the Leverage Ratio as the ratio of Consolidated Total Debt as of the last day of a quarter (“Test Date”) to Consolidated EBITDA for the four consecutive quarters preceding the Test Date, each as defined in the Credit Facility.

Debt Service Coverage Ratio.  The Debt Service Coverage Ratio must be at least 2.00 to 1.00, with increases to 2.25 to 1.00 for the period commencing September 30, 2014 to September 29, 2015, and to 2.50 to 1.00 for the period commencing September 30, 2015 and thereafter. The Credit Facility defines the Debt Service Coverage Ratio as the ratio of Consolidated EBITDA minus Consolidated Capital Expenditures to Scheduled Repayments plus Consolidated Adjusted Interest Expense, each as defined in the Credit Facility.

With respect to these covenant compliance calculations, Consolidated EBITDA, as defined in the Credit Facility (hereinafter, referred to as “Credit Facility EBITDA”), differs from typical EBITDA calculations and our calculation of Adjusted EBITDA, which is used in certain of our public releases and in connection with our incentive compensation plan.

– 30 –

The most significant difference in the Credit Facility EBITDA calculation is the inclusion of cash payments for environmental remediation as part of the calculation. The following statements summarize the elements of those definitions that are material to our computations. Consolidated Total Debt generally includes principal amounts outstanding under our Credit Facility, capital leases, drawn amounts for outstanding letters of credit and other indebtedness for borrowed money. Credit Facility EBITDA is generally computed as consolidated net income (loss) plus income tax expense (benefit), interest expense, depreciation and amortization, stock-based compensation expense, and certain non-cash charges and less cash payments for environmental remediation, extraordinary gains and certain other non-cash gains. In accordance with the definitions contained in the Credit Facility, as of December 31, 2012, our Leverage Ratio was 1.34 to 1.00 and our Debt Service Coverage Ratio was 5.63 to 1.00.

The Credit Facility also contains usual and customary events of default (subject to certain threshold amounts and grace periods). If an event of default occurs and is continuing, the Company may be required to repay the obligations under the Credit Facility prior to the Credit Facility’s stated maturity and the related commitments may be terminated.

Interest Rate Swap Agreement. On January 24, 2013, we entered into a floating-to-fixed interest rate swap with an initial notional amount of $58,875 (such notional amount reducing over the life of the arrangement), terminating October 26, 2017, which will effectively convert our floating-rate debt to a fixed rate. Under the terms of the swap, we will pay a fixed rate of approximately 0.775% and we will receive a floating-rate payment tied to the one-month LIBOR.

PENSION BENEFITS. We maintain three defined benefit pension plans which cover substantially all of our employees: the Amended and Restated American Pacific Corporation Defined Benefit Pension Plan, the Ampac Fine Chemicals LLC Pension Plan for Salaried Employees, and the Ampac Fine Chemicals LLC Pension Plan for Bargaining Unit Employees, each as amended to date. Collectively, these three plans are referred to as the “Pension Plans”. In May 2010, our board of directors approved amendments to our Pension Plans which effectively closed the Pension Plans to participation by any new employees. Retirement benefits for existing U.S. employees and retirees through June 30, 2010 were not affected by this change. Beginning July 1, 2010, new U.S. employees began participating solely in one of our 401(k) plans. Pension Plan benefits are paid based on an average of earnings, retirement age, and length of service, among other factors.

Benefit obligations are measured annually as of September 30. As of September 30, 2012, the Pension Plans had an unfunded benefit obligation of $44,740. For Fiscal 2012, we made contributions to the Pension Plans in the amount of $9,320. We anticipate making Pension Plan contributions in the amount of approximately $6,704 during Fiscal 2013. We are required to make minimum contributions to our Pension Plans pursuant to the minimum funding requirements of the Internal Revenue Code of 1986, as amended, and the Employee Retirement Income Security Act of 1974, as amended. In accordance with federal requirements, our minimum funding obligations are determined annually based on a measurement date of October 1. The fair value of Pension Plan assets is a key factor in determining our minimum funding obligations. Holding all other variables constant, a 10% decline in asset value as of September 30, 2012 would increase our minimum funding obligations for Fiscal 2013 by approximately $295.

In addition, we maintain the American Pacific Corporation Supplemental Executive Retirement Plan, as amended and restated (the “SERP”), that includes three active and two former executive officers. The SERP is an unfunded plan and as of September 30, 2012 the SERP obligation was $11,087. For Fiscal 2012, we paid SERP retirement benefits of $527. We anticipate contributing the amount of approximately $528 to the SERP during Fiscal 2013 for the payment of retirement benefits. Payments for retirement benefits should increase in future years when each of the three current active participants retires. The future increase in such retirement benefits will be determined based on certain variables including each participating individual’s actual retirement date, rate of compensation and years of service.

– 31 –

During Fiscal 2012 and Fiscal 2011, our aggregate Pension Plans and SERP liability increased significantly primarily due to reductions in the actuarial assumption for the discount rate on the obligation, returns on plan assets at levels substantially lower than the expected long-term rate of return on plan assets and losses on certain plan assets. These changes are recorded as an increase in Pension Obligations and a corresponding decrease in Stockholders’ Equity (Accumulated Other Comprehensive Loss). If interest rates remain low and/or returns on plan assets do not trend with the expected long-term rate of return, our liquidity could be impacted by pension plan funding requirements.

ENVIRONMENTAL REMEDIATION – AMPAC HENDERSON SITE.  During the fiscal years ended September 30, 2005 and September 30, 2006, we recorded aggregate charges of $26,000 representing our estimates at the time of the probable costs of our remediation efforts at our former perchlorate chemicals manufacturing facility in Henderson, Nevada (the “AMPAC Henderson Site”), including the costs for capital equipment and on-going operating and maintenance (“O&M”).

Late in Fiscal 2009, we gained additional information from groundwater modeling that indicates groundwater emanating from the AMPAC Henderson Site in certain areas in deeper zones (more than 150 feet below ground surface) is moving toward our existing remediation facility at a much slower pace than previously estimated. Utilization of our existing facilities alone, at this slower groundwater pace, could, according to this groundwater model, extend the life of our remediation project to well in excess of fifty years. As a result of this additional data, related model interpretations and consultations with the Nevada Division of Environmental Protection (“NDEP”), we re-evaluated our remediation operations and determined that we should be able to improve the effectiveness of the treatment program and significantly reduce the total project time by expanding the treatment system existing at the time. The expansion includes installation of additional groundwater extraction wells in the deeper, more concentrated areas, construction of an underground pipeline to move extracted groundwater to our treatment facility, and the addition of fluidized bed reactor (“FBR”) bioremediation treatment equipment (the “Expansion Project”) that will enhance, and in some cases replace, primary components of the existing treatment system. In our Fiscal 2009 fourth quarter, we accrued $13,700 as our initial estimate of the capital cost of the Expansion Project and the related estimates of the effects of the enhanced operations on the on-going O&M costs and project life.

Through June 2011, and in cooperation with NDEP, we worked to develop the formal design, engineering and permitting of the Expansion Project. Based on data obtained through that date, which was largely comprised of firm quotations, we determined that significant modifications to our Fiscal 2009 assumptions were required. As a result, in June 2011, we accrued an additional $6,000 for the estimated increase in cost of the capital component of the Expansion Project, offset slightly by reductions in O&M cost estimates. The estimated capital costs of the Expansion Project increased by approximately $6,400. The increase reflects (i) an increase in the capacity of the FBR bioremediation treatment equipment to accommodate technical requirements based on the testing of new extraction wells in the fall of 2010, and (ii) higher than initially anticipated cost associated with the installation of the equipment and construction of the pipeline. Our estimate of total O&M costs was reduced by approximately $400.

In September 2012, we commenced initial operation of the Expansion Project. Related system optimization and other start-up activities will continue into Fiscal 2013. In September 2012, we recorded an additional remediation charge in the amount of $700, which is substantially attributed to the true-up of estimates to the expected final cost of the expansion project. Due to uncertainties inherent in making estimates, our estimates of capital and O&M costs may later require significant revision as new facts become available and circumstances change.

The estimated life of the project is a key assumption underlying the accrued estimated cost of our remediation activities. Groundwater modeling and other information regarding the characteristics of the surrounding land and demographics indicate that at our targeted processing rate of 450 gallons per minute for the new groundwater extraction wells (750 gallons per minute in the aggregate with existing wells), the life of the project could range from 5 to 18 years from the date that the Expansion Project was placed in service. Further, the data indicates that within that range, 7 to 14 years is

– 32 –

the more likely range. In accordance with generally accepted accounting principles, if no point within the more likely range is considered more likely than another, then estimates should be based on the low end of the range. Accordingly, our accrued remediation cost includes estimated O&M costs through 2019, which is the low end of the likely range of the project life. Groundwater speed, perchlorate concentrations, aquifer characteristics and forecasted groundwater extraction rates will continue to be key factors considered when estimating the life of the project. If additional information becomes available in the future that leads to a different interpretation of the model, thereby dictating a change in equipment and operations, our estimate of the resulting project life could change significantly.

The estimate of the annual O&M cost of the project is a key assumption in our computation of the estimated cost of our remediation activities. To estimate O&M costs, we consider, among other factors, the project scope and historical expense rates to develop assumptions regarding labor, utilities, repairs, maintenance supplies and professional services costs. We estimate average annual O&M costs to be approximately $1,900. If additional information becomes available in the future that is different than information currently available to us and thereby leads us to different conclusions, our estimate of O&M expenses could change significantly.

In addition, certain remediation activities are conducted on public lands under operating permits. In general, these permits may require us to relocate our underground pipeline or equipment to accommodate future public utilities and features and require us to return the land to its original condition at the end of the permit period. If we are required to relocate our underground pipeline or equipment in the future, the costs of such activities would be incremental to our current cost estimates. Estimated costs associated with removal of remediation equipment from the land are not material and are included in our range of estimated costs.

As of December 31, 2012, the aggregate range of anticipated environmental remediation costs was from approximately $10,900 to approximately $34,800. This range represents a significant estimate and is based on the estimable elements of cost for capital and O&M costs, and an estimated remaining operating life of the project through a range from the years 2017 to 2030. As of December 31, 2012, the accrued amount was $14,666, based on an estimated remaining life of the project through the year 2019, or the low end of the more likely range of the expected life of the project. Cost estimates are based on our current assessments of the facility configuration. As we proceed with the project, we have, and may in the future, become aware of elements of the facility configuration that must be changed to meet the targeted operational requirements. Certain of these changes may result in corresponding cost increases. Costs associated with the changes are accrued when a reasonable alternative, or range of alternatives, is identified and the cost of such alternative is estimable. Our estimated reserve for environmental remediation is based on information currently available to us and may be subject to material adjustment upward or downward in future periods as new facts or circumstances may indicate.

Letters of Credit. As of December 31, 2012, we had $385 in outstanding standby letters of credit which mature through April 2016. These letters of credit principally secure performance of certain water treatment equipment sold by us. The letters of credit are collateralized by cash on deposit with the issuing bank in the amount of 105% of the outstanding letters of credit. Collateral deposits are classified as other assets on our consolidated balance sheets.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires that we adopt accounting policies and make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses.

– 33 –

Application of the critical accounting policies discussed below requires significant judgment, often as the result of the need to make estimates of matters that are inherently uncertain. If actual results were to differ materially from the estimates made, the reported results could be materially affected. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.

SALES AND REVENUE RECOGNITION. We recognize revenues when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, title passes, the price is fixed or determinable and collectability is reasonably assured. Almost all products sold by our Fine Chemicals segment are subject to customer acceptance periods. Specifically, these customers have contractually negotiated acceptance periods from the time they receive certificates of analysis and compliance (“Certificates”) to reject the material based on issues with the quality of the product, as defined in the applicable agreement. At times we receive payment in advance of customer acceptance. If we receive payment in advance of customer acceptance, we record deferred revenues and deferred costs of revenue upon delivery of the product and recognize revenues in the period when the acceptance period lapses or the customer’s acceptance has occurred.

Some of our perchlorate and fine chemicals products customers have requested that we store materials purchased from us in our facilities (“Bill and Hold” transactions or arrangements). We recognize revenue prior to shipment of these Bill and Hold transactions when we have satisfied the applicable revenue recognition criteria, which include the point at which title and risk of ownership transfer to our customers. These customers have specifically requested in writing, pursuant to a contract, that we invoice for the finished product and hold the finished product until a later date. For our Bill and Hold arrangements that contain customer acceptance periods, we record deferred revenues and deferred costs of revenues when such products are available for delivery and Certificates have been delivered to the customers. We recognize revenue on our Bill and Hold transactions in the period when the acceptance period lapses or the customer’s acceptance has occurred. The sales value of inventory, subject to Bill and Hold arrangements, at our facilities was $18,217 and $19,346 as of December 31, 2012 and September 30, 2012, respectively.

DEPRECIABLE OR AMORTIZABLE LIVES OF LONG-LIVED ASSETS. Our depreciable or amortizable long-lived assets include property, plant and equipment, which are recorded at cost. Depreciation or amortization is recorded using the straight-line method over the shorter of the asset’s estimated economic useful life or the lease term, if the asset is subject to a capital lease. Economic useful life is the duration of time that we expect the asset to be productively employed by us, which may be less than its physical life. Significant assumptions that affect the determination of estimated economic useful life include: wear and tear, obsolescence, technical standards, contract life, and changes in market demand for products.

The estimated economic useful life of an asset is monitored to determine its appropriateness, especially in light of changed business circumstances. For example, changes in technological advances, changes in the estimated future demand for products, or excessive wear and tear may result in a shorter estimated useful life than originally anticipated. In these cases, we would depreciate the remaining net book value over the new estimated remaining life, thereby increasing depreciation expense per year on a prospective basis. Likewise, if the estimated useful life is increased, the adjustment to the useful life decreases depreciation expense per year on a prospective basis.

IMPAIRMENT OF LONG-LIVED ASSETS. We test our property, plant and equipment for recoverability when events or changes in circumstances indicate that their carrying amounts may not be recoverable. Examples of such circumstances include, but are not limited to, operating or cash flow losses from the use of such assets or changes in our intended uses of such assets. To test for recovery, we group assets (an “Asset Group”) in a manner that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Our Asset Groups are typically identified by facility because each facility has a unique cost overhead and general and administrative expense structure that is supported by cash flows from products produced at the facility. The carrying amount of an Asset Group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the Asset Group.

– 34 –

If we determine that an Asset Group is not recoverable, then we would record an impairment charge if the carrying value of the Asset Group exceeds its fair value. Fair value is based on estimated discounted future cash flows expected to be generated by the Asset Group. The assumptions underlying cash flow projections would represent management’s best estimates at the time of the impairment review. Some of the factors that management would consider or estimate include: industry and market conditions, sales volume and prices, costs to produce and inflation. Changes in key assumptions or actual conditions that differ from estimates could result in an impairment charge. We use reasonable and supportable assumptions when performing impairment reviews, but cannot predict the occurrence of future events and circumstances that could result in impairment charges.

When we review Asset Groups for recoverability, we also consider depreciation estimates and methods or the amortization period, in each case as required by applicable accounting standards. Any revision to the remaining useful life of a long-lived asset resulting from that review also is considered in developing estimates of future cash flows used to test the Asset Group for recoverability.

ENVIRONMENTAL COSTS. We are subject to environmental regulations that relate to our past and current operations. We record liabilities for environmental remediation costs when our assessments indicate that remediation efforts are probable and the costs can be reasonably estimated. On a quarterly basis, we review our estimates of future costs that could be incurred for remediation activities. In some cases, only a range of reasonably possible costs can be estimated. In establishing our reserves, the most probable estimate is used; otherwise, we accrue the minimum amount of the range. Estimates of liabilities are based on currently available facts, existing technologies and presently enacted laws and regulations. These estimates are subject to revision in future periods based on actual costs or new circumstances. Accrued environmental remediation costs include the undiscounted cost of equipment, operating and maintenance costs, and fees to outside law firms and consultants, for the estimated duration of the remediation activity and do not include an assumption for inflation. Estimating environmental cost requires us to exercise substantial judgment regarding the cost, effectiveness and duration of our remediation activities. Actual future expenditures could differ materially from our current estimates.

We evaluate potential claims for recoveries from other parties separately from our estimated liabilities. We record an asset for expected recoveries when recoveries of the amounts are probable.

INCOME TAXES. We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured, separately for each tax-paying entity in each tax jurisdiction, using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date.

When measuring deferred tax assets, we assess whether a valuation allowance should be established by evaluating both positive and negative factors. This evaluation requires that we exercise judgment in determining the relative significance of each factor. A valuation allowance is established if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The assessment of valuation allowance requirements, if any, involves significant estimates regarding the timing and amount of reversal of taxable temporary differences, future taxable income and the implementation of tax planning strategies. We rely on deferred tax liabilities in our assessment of the realizability of deferred tax assets if the temporary timing difference is anticipated to reverse in the same period and jurisdiction and the deferred tax liabilities are of the same character as the temporary differences giving rise to the deferred tax assets. We weigh both positive and negative evidence in determining whether it is more likely than not that a valuation allowance is required. Greater weight is given to evidence which is objectively verifiable such as historical results. If we report a cumulative loss from continuing operations before income taxes for a three-year period, we do not rely on forecasted improvements in earnings to recover deferred tax assets.

– 35 –

We account for uncertain tax positions in accordance with an accounting standard which creates a single model to address uncertainty in income tax positions and prescribes the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. The standard also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Under this standard, we may recognize tax benefits from an uncertain position only if it is more likely than not that the position will be sustained upon examination by taxing authorities based on the technical merits of the issue. The amount recognized is the largest benefit that we believe has greater than a 50% likelihood of being realized upon settlement. Actual income taxes paid may vary from estimates depending upon changes in income tax laws, actual results of operations, and the final audit of tax returns by taxing authorities. Tax assessments may arise several years after tax returns have been filed.

PENSION BENEFITS.  We sponsor four defined benefit pension plans in various forms for employees who meet eligibility requirements. Applicable accounting standards require that we make assumptions and use statistical variables in actuarial models to calculate our pension obligations and the related periodic pension expense. The most significant assumptions are the discount rate and the expected rate of return on plan assets. Additional assumptions include the future rate of compensation increases, which is based on historical plan data and assumptions on demographic factors such as retirement, mortality and turnover. Depending on the assumptions selected, pension expense could vary significantly and could have a material effect on reported earnings. The assumptions used can also materially affect the measurement of benefit obligations.

The discount rate is used to estimate the present value of projected future pension payments to all participants. The discount rate is generally based on the yield on AAA/AA-rated corporate long-term bonds. At September 30 of each year, the discount rate is determined using bond yield curve models matched with the timing of expected retirement plan payments. Our discount rate assumption was 5.40 percent as of September 30, 2012. Holding all other assumptions constant, a hypothetical increase or decrease of 25 basis points in the discount rate assumption would increase or decrease annual pension expense by approximately $526.

The expected long-term rate of return on plan assets represents the average rate of earnings expected on the plan funds invested in a specific target asset allocation. The expected long-term rate of return assumption on pension plan assets was 8.00 percent in Fiscal 2012. Holding all other assumptions constant, a hypothetical 25 basis point increase or decrease in the assumed long-term rate of return would increase or decrease annual pension expense by approximately $131.

RECENTLY ISSUED OR ADOPTED ACCOUNTING STANDARDS.  In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, which amends Topic 220, Comprehensive Income. The amendment allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements, and eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. This standard was effective for us beginning on October 1, 2012. This standard changes presentation requirements, and accordingly, the adoption of this standard did not have an impact on our results of operations, financial position or cash flows.

ITEM 4. CONTROLS AND PROCEDURES

Based on their evaluation as of December 31, 2012, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) were effective as of such date to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure, and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

There were no changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.  OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Although we are not currently party to any material pending legal proceedings, we are from time to time subject to claims and lawsuits related to our business operations. Any such claims and lawsuits could be costly and time consuming and could divert our management and key personnel from our business operations. In connection with any such claims and lawsuits, we may be subject to significant damages or equitable remedies relating to the operation of our business. Any such claims and lawsuits may materially harm our business, results of operations and financial condition.

ITEM 1A. RISK FACTORS (Dollars in Thousands)

This description includes any material changes to and supersedes the description of the risk factors associated with our business previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K for Fiscal 2012. The following risk factors should be considered carefully before you decide whether to buy, hold or sell our common stock. Additional risks not presently known to us or that we currently deem immaterial may also impair our business, financial condition, results of operations and stock price. We report our results based on a fiscal year which ends on September 30. References to Fiscal years refer to the twelve months ended or ending September 30 of the Fiscal year referenced.

We depend on a limited number of customers for most of our sales and the loss of one or more of these customers could have a material adverse effect on our financial position, results of operations and cash flows.

Most of the perchlorate chemicals we produce, which accounted for 88% of our revenues in the Specialty Chemicals segment for Fiscal 2012 and approximately 33% of our consolidated revenues for Fiscal 2012, are purchased by two customers. Should our relationship with one or more of our major Specialty Chemicals customers change adversely, the resulting loss of business could have a material adverse effect on our financial position, results of operations and cash flows. In addition, if one or more of our major Specialty Chemicals customers substantially reduced their volume of purchases from us or otherwise delayed some or all of their purchases from us, it could have a material adverse effect on our financial position, results of operations and cash flows. Should one of our major Specialty Chemicals customers encounter financial difficulties, the exposure on uncollectible receivables and unusable inventory could have a material adverse effect on our financial position, results of operations and cash flows.

Furthermore, our Fine Chemicals segment’s success is largely dependent upon the manufacturing by AFC of a limited number of registered intermediates and active pharmaceutical ingredients for a limited number of key customers. One customer of AFC accounted for 31% of our consolidated revenue and the top two customers of AFC accounted for approximately 72% of its revenues, and 43% of our consolidated revenues, in Fiscal 2012. Negative developments in these customer relationships or in either of the customer’s business, or failure to renew or extend certain contracts, may have a material adverse effect on the results of operations of AFC. Moreover, from time to time key customers have reduced their orders, and one or more of these customers might reduce their orders in the future, or one or more of them may attempt to negotiate lower prices, any of which could have a similar negative effect on the results of operations of AFC. If the pharmaceutical products that AFC’s customers produce using its compounds experience any problems, including problems related to their safety or efficacy, delays in filing with or approval by the FDA, or other regulatory agencies, failures in achieving success in the market, expiration or loss of patent/regulatory protection, or competition, including competition from generic drugs, these customers may substantially reduce or cease to purchase AFC’s compounds, which could have a material adverse effect on the revenues and results of operations of AFC.

The inherent limitations of our fixed-price or similar contracts may impact our profitability.

A substantial portion of our revenues are derived from our fixed-price or similar contracts. When we enter into fixed-price contracts, we agree to perform the scope of work specified in the contract for a predetermined price. Many of our fixed-price or similar contracts require us to provide a customized product over a long period at a pre-established price or prices for such product. For example, when AFC is initially engaged to manufacture a product, we often agree to set the price for such product, and any time-based increases to such price, at the beginning of the contracting period and prior to fully testing and beginning the customized manufacturing process. Depending on the fixed price negotiated, these contracts may provide us with an opportunity to achieve higher profits based on the relationship between our total estimated contract costs and the contract’s fixed price. However, we bear the risk that increased or unexpected costs, or external factors that may impact contract costs, fixed prices or profit yields, such as fluctuations in international currency exchange rates, may reduce our profit or cause us to incur a loss on the contract, which could reduce our net sales and net earnings. Ultimately, fixed-price contracts and similar types of contracts present the inherent risk of un-reimbursed cost overruns and unanticipated external factors that negatively impact contract costs, fixed prices or profit yields, any of which could have a material adverse effect on our operating results, financial condition, or cash flows. Moreover, to the extent that we do not anticipate the increase in cost or the effect of external factors over time on the production or pricing of the products which are the subject of our fixed-price contracts, our profitability could be adversely affected.

The numerous and often complex laws and regulations and regulatory oversight to which our operations and properties are subject, the cost of compliance, and the effect of any failure to comply could reduce our profitability and liquidity.

The nature of our operations subject us to extensive and often complex and frequently changing federal, state, local and foreign laws and regulations and regulatory oversight, including with respect to emissions to air, discharges to water and waste management as well as with respect to the sale and, in certain cases, export of controlled products. For example, in our Fine Chemicals segment, modifications, enhancements or changes in manufacturing sites of approved products are subject to complex regulations of the FDA, and, in many circumstances, such actions may require the express approval of the FDA, which in turn may require a lengthy application process and, ultimately, may not be obtainable. The facilities of AFC are periodically subject to scheduled and unscheduled inspection by the FDA and other governmental agencies. Operations at these facilities could be interrupted or halted if such inspections are unsatisfactory and we could experience fines and/or other regulatory actions if we are found not to be in regulatory compliance. AFC’s customers face similarly high regulatory requirements. Before marketing most drug products, AFC’s customers generally are required to obtain approval from the FDA based upon pre-clinical testing, clinical trials showing safety and efficacy, chemistry and manufacturing control data, and other data and information. The generation of these required data is regulated by the FDA and can be time-consuming and expensive, and the results might not justify approval. In some cases, approval is required from other regulatory agencies such as the DEA. Even if AFC’s customers are successful in obtaining all required pre-marketing approvals, post-marketing requirements and any failure on either AFC’s or its customers’ part to comply with other regulations could result in suspension or limitation of approvals or commercial activities pertaining to affected products.

Because we operate in highly regulated industries, we may be affected significantly by legislative and other regulatory actions and developments concerning or impacting various aspects of our operations and products or our customers. To meet changing licensing and regulatory standards, we may be required to make additional significant site or operational modifications, potentially involving substantial expenditures or the reduction or suspension of certain operations. For example, in our Fine Chemicals segment, any regulatory changes could impose, on AFC or its customers, changes to manufacturing methods or facilities, pharmaceutical importation, expanded or different labeling, new approvals, the recall, replacement or discontinuance of certain products, additional record keeping, testing, price or purchase controls or limitations, and expanded documentation of the properties of certain products and scientific substantiation. AFC’s failure to comply with governmental regulations, in particular those of the FDA and DEA, can result in fines, unanticipated compliance expenditures, recall or seizure of products, delays in, or total or partial suspension or withdrawal of, approval

– 39 –

of production or distribution, suspension of the FDA’s review of relevant product applications, termination of ongoing research, disqualification of data for submission to regulatory authorities, enforcement actions, injunctions and criminal prosecution. Under certain circumstances, the FDA also has the authority to revoke previously granted drug approvals. Although we have instituted internal compliance programs, if regulations or the standards by which they are enforced change and/or compliance is deficient in any significant way, such as a failure to materially comply with the FDA’s current Good Manufacturing Practices or “cGMP” guidelines, or if a regulatory authority asserts publically or otherwise such a deficiency or takes action against us whether or not the underlying asserted deficiency is ultimately found to be sustainable, it could have a material adverse effect on us. In our Specialty Chemicals and Fine Chemicals segments, changes in environmental regulations could result in requirements to add or modify emissions control, water treatment, or waste handling equipment, processes or arrangements, which could impose significant additional costs for equipment at and operation of our facilities.

Moreover, in other areas of our business, we, like other government and military subcontractors, are subject indirectly in many cases to government contracting regulations and the additional costs, burdens and risks associated with meeting these heightened contracting requirements. Failure to comply with government contracting regulations may result in contract termination, the potential for substantial civil and criminal penalties, and, under certain circumstances, our suspension and debarment from future U.S. government contracts for a period of time. For example, these consequences could be imposed for failing to follow procurement integrity and bidding rules, employing improper billing practices or otherwise failing to follow cost accounting standards, receiving or paying kickbacks or filing false claims. In addition, the U.S. government and its principal prime contractors periodically investigate the U.S. government’s subcontractors, including with respect to financial viability, as part of the U.S. government’s risk assessment process associated with the award of new contracts. Consequently, for example, if the U.S. government or one or more prime contractors were to determine that we were not financially viable, our ability to continue to act as a government subcontractor would be impaired. Further, a portion of our business involves the sale of controlled products overseas, such as supplying ammonium perchlorate, or “AP”, to various foreign defense programs and commercial space programs. Foreign sales subject us to numerous additional complex U.S. and foreign laws and regulations, including laws and regulations governing import-export controls applicable to the sale and export of munitions and other controlled products and commodities, repatriation of earnings, exchange controls, the Foreign Corrupt Practices Act, and the anti-boycott provisions of the U.S. Export Administration Act. The costs of complying with the various and often complex and frequently changing laws and regulations and regulatory oversight applicable to us and the businesses in which we engage, and the consequences should we fail to comply, even inadvertently, with such requirements, could be significant and could reduce our profitability and liquidity.

A significant portion of our business is based on contracts with contractors or subcontractors to the U.S. government and these contracts are impacted by governmental priorities and are subject to potential fluctuations in funding or early termination, including for convenience, any of which could have a material adverse effect on our operating results, financial condition or cash flows.

Sales to U.S. government prime contractors and subcontractors represent a significant portion of our business. We also make sales to the U.S. government from time to time. In Fiscal 2012, our Specialty Chemicals segment generated approximately 30% of consolidated revenues, primarily sales of rocket-grade AP, from sales to U.S. government prime contractors and subcontractors. Funding of U.S. governmental programs is generally subject to annual congressional appropriations, and congressional priorities are subject to change. In the case of major programs, U.S. government contracts are usually incrementally funded. In addition, U.S. government expenditures for defense and NASA programs may fluctuate from year to year and specific programs, in connection with which we may receive significant revenue, may be terminated or curtailed. For example, one significant use of rocket-grade AP historically has been in NASA’s Space Shuttle program. Consequently, with the recent retirement of the Space Shuttle fleet, the long-term demand for rocket-grade AP may be uncertain. While rocket-grade AP volume increased in Fiscal 2012, supported by the return in Fiscal 2012 of quantities for development motors for the NASA’s Heavy Launch Vehicle (“HLV”) which is part of the new Space Launch System, the HLV is still in the development phase and NASA could shift away from the use of AP as the

– 40 –

oxidizing agent for solid propellant rockets or the use of solid propellant rockets in NASA’s space exploration programs in the future. If the use of AP as the oxidizing agent for solid propellant rockets or the use of solid propellant rockets in NASA’s space exploration programs are discontinued or significantly reduced, it could have a material adverse effect on our operating results, financial condition, or cash flows.

Recent economic crises, and the U.S. government’s corresponding actions, may result in cutbacks in major government programs. A decline in government expenditures or any failure by Congress to appropriate additional funds to any program in which we or our customers participate, or any contract modification as a result of funding changes, could materially delay or terminate the program for us or for our customers. Moreover, the U.S. government may terminate its contracts with its suppliers either for its convenience or in the event of a default by the supplier. Since a significant portion of our customer base is U.S. government contractors or subcontractors, we may have limited ability to collect fully on our contracts when the U.S. government terminates its contracts. If a contract is terminated by the U.S. government where we are a subcontractor, the U.S. government contractor may cease purchasing our products if its contracts are terminated. We may have resources applied to specific government-related contracts and, if any of those contracts were terminated, we may incur substantial costs redeploying these resources. Given the significance to our business of contracts based on U.S. government contracts, fluctuations or reductions in governmental funding for particular governmental programs and/or termination of existing governmental programs and related contracts may have a material adverse effect on our operating results, financial condition or cash flows.

We may be subject to potentially material costs and liabilities in connection with environmental or health matters.

Some of our operations may create risks of adverse environmental and health effects, any of which might not be covered by insurance. In the past, we have been required to take remedial action to address particular environmental and health concerns identified by governmental agencies in connection with the production of perchlorate. It is possible that we may be required to take further remedial action in the future in connection with our production of perchlorate, whether at our former facility in Henderson, Nevada, or at our current production facility in Iron County, Utah, or we may enter voluntary agreements with governmental agencies to take such actions. Moreover, in connection with other operations, we may become obligated in the future for environmental liabilities if we fail to abide by limitations placed on us by governmental agencies. There can be no assurance that material costs or liabilities will not be incurred or restrictions will not be placed upon us in order to rectify any past or future occurrences related to environmental or health matters. Such material costs or liabilities, or increases in, or charges associated with, existing environmental or health-related liabilities, also may have a material adverse effect on our operating results, earnings or financial condition.

Review of Perchlorate Toxicity by the EPA. Currently, perchlorate is on the EPA’s Contaminant Candidate List 3. In February 2011, the EPA announced that it had determined to move forward with the development of a regulation for perchlorates in drinking water, reversing its October 2008 preliminary determination not to promulgate such a regulation. Accordingly, the EPA announced its intention to begin to evaluate the feasibility and affordability of treatment technologies to remove perchlorate and to examine the costs and benefits of potential standards. At the time, the EPA stated that its intention was to publish a proposed regulation and analyses for public review and comment within 24 months, and, if a regulation is adopted, to promulgate a final regulation within 18 months after publication of its proposal. Regulatory review and anticipated regulatory actions present general business risk to us, but no regulatory proposal of the EPA or any state in which we operate, to date, has been publicly announced that we believe would have a material effect on our results of operations and financial position or that would cause us to significantly modify or curtail our business practices, including our remediation activities discussed below.

However, the outcome of the federal EPA action, as well as any similar state regulatory action, will influence the number, if any, of potential sites that may be subject to remediation action, which could, in turn, cause us to incur material costs. It is possible that federal and, potentially, one or more state or local regulatory agencies may change existing, or establish

– 41 –

new, standards for perchlorate, which could lead to additional expenditures for environmental remediation in the future, and/or additional, potentially material costs to defend against new claims resulting from such regulatory agency actions.

Perchlorate Remediation Project in Henderson, Nevada. We commercially manufactured perchlorate chemicals at a facility in Henderson, Nevada, or the “AMPAC Henderson Site,” until May 1988. In 1997, the Southern Nevada Water Authority, or SNWA, detected trace amounts of the perchlorate anion in Lake Mead and the Las Vegas Wash. Lake Mead is a source of drinking water for Southern Nevada and areas of Southern California. The Las Vegas Wash flows into Lake Mead from the Las Vegas valley. In response to this discovery by SNWA, and at the request of the Nevada Division of Environmental Protection, or NDEP, we engaged in an investigation of groundwater near the AMPAC Henderson Site and down gradient toward the Las Vegas Wash. At the direction of NDEP and the EPA, we conducted an investigation of remediation technologies for perchlorate in groundwater with the intention of remediating groundwater near the AMPAC Henderson Site. In Fiscal 2005, we submitted a work plan to NDEP for the construction of a remediation facility near the AMPAC Henderson Site. The permanent plant began operation in December 2006. Late in Fiscal 2009, we gained additional information from groundwater modeling that indicates groundwater emanating from the AMPAC Henderson Site in certain areas in deeper zones (more than 150 feet below ground surface) is moving toward our existing remediation facility at a much slower pace than previously estimated. As a result of this additional data, related model interpretations and consultations with NDEP, we re-evaluated our remediation operations and determined that we should be able to improve the effectiveness of the treatment program and significantly reduce the total project time by expanding the treatment system existing at the time. The expansion includes the installation of additional groundwater extraction wells in the deeper, more concentrated areas, construction of an underground pipeline to move extracted groundwater to our treatment facility, and the addition of fluidized bed reactor (“FBR”) bioremediation treatment equipment (the “Expansion Project”).

Henderson Site Environmental Remediation Reserve. During Fiscal 2005 and Fiscal 2006, we recorded aggregate charges of $26,000 representing our estimates at the time of the probable costs of our remediation efforts at the AMPAC Henderson Site, including the costs for capital equipment and on-going operating and maintenance (“O&M”). Following the receipt of new data regarding groundwater movement late in Fiscal 2009, we added the Expansion Project to the planned scope of our remediation operations. As a result, we increased our accruals by approximately $13,700.

Through June 2011, and in cooperation with NDEP, we worked to develop the formal design and engineering of the Expansion Project. Based on data obtained through that date, which was largely comprised of firm quotations, we determined that significant modifications to our Fiscal 2009 assumptions were required. As a result, in June 2011, we accrued an additional $6,000 for the estimated increase in cost of the capital component of the Expansion Project, offset slightly by reductions in O&M cost estimates. The estimated capital costs of the Expansion Project increased by approximately $6,400. The increase reflected (i) an increase in the capacity of the FBR bioremediation treatment equipment to accommodate technical requirements based on the testing of new extraction wells in the fall of 2010, and (ii) higher than initially anticipated cost associated with the installation of the equipment and construction of the pipeline. Our estimate of total O&M costs was reduced by approximately $400. Due to uncertainties inherent in making estimates, our estimates of capital and O&M costs may later require significant revision as new facts become available and circumstances change.

In September 2012, we commenced initial operation of the Expansion Project. Related system optimization and other start-up activities will continue into Fiscal 2013. In September 2012, we recorded an additional remediation charge in the amount of $700, which is substantially attributed to the true-up of estimates to the expected final cost of the expansion project. Due to uncertainties inherent in making estimates, our estimates of capital and O&M costs may later require significant revision as new facts become available and circumstances change.

As of December 31, 2012, the aggregate range of anticipated environmental remediation costs was from approximately $10,900 to approximately $34,800. This range represents a significant estimate and is based on the estimable elements of cost for capital and O&M costs, and an estimated remaining operating life of the project through a range from the

– 42 –

years 2017 to 2030. As of December 31, 2012, the accrued amount was $14,666, based on an estimated remaining life of the project through the year 2019, or the low end of the more likely range of the expected life of the project. Cost estimates are based on our current assessments of the facility configuration. As we have proceeded with the project, we have, and may in the future, become aware of elements of the facility configuration that must be changed to meet the targeted operational requirements. Certain of these changes may result in corresponding cost increases. Costs associated with the changes are accrued when a reasonable alternative, or range of alternatives, is identified and the cost of such alternative is estimable. Our estimated reserve for environmental remediation is based on information currently available to us and may be subject to material adjustment upward or downward in future periods as new facts or circumstances may indicate.

Other Environmental Matters. As part of our acquisition of the fine chemicals business of GenCorp Inc., AFC leased 241 acres of land on a Superfund site in Rancho Cordova, California, owned by Aerojet-General Corporation, a wholly-owned subsidiary of GenCorp Inc. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, or CERCLA, has very strict joint and several liability provisions that make any “owner or operator” of a “Superfund site” a “potentially responsible party” for remediation activities. AFC could be considered an “operator” for purposes of CERCLA and, in theory, could be a potentially responsible party for purposes of contribution to the site remediation, although we received a letter from the EPA in November 2005 indicating that the EPA does not intend to pursue any clean up or enforcement actions under CERCLA against future lessees of the Aerojet property for existing contamination, provided that the lessees do not contribute to or do not exacerbate existing contamination on or under the Superfund site. Additionally, pursuant to the EPA consent order governing remediation for this site, AFC must abide by certain limitations regarding construction and development of the site which may restrict AFC’s operational flexibility and require additional substantial capital expenditures that could negatively affect the results of operations for AFC.

Although we have established an environmental reserve for remediation activities in Henderson, Nevada, given the many uncertainties involved in assessing environmental liabilities, our environmental-related risks may exceed any related reserves.

As of December 31, 2012, we had recorded reserves in connection with the AMPAC Henderson Site of approximately $14,666. However, as of such date, we had not established any other environmental-related reserves. Given the many uncertainties involved in assessing and estimating environmental liabilities, our environmental-related risks may exceed any related reserves, as we may not have established reserves with respect to such environmental liabilities, or any reserves we have established may prove to be insufficient. We continually evaluate the adequacy of our reserves on a quarterly basis, and they could change. For example, during the quarter ended June 30, 2011, we increased our environmental reserves in connection with the AMPAC Henderson Site by approximately $6,000 as a result of an increase in anticipated costs associated with remediation efforts at the site. In addition, reserves with respect to environmental matters are based only on known sites and the known contamination at those sites. It is possible that additional remediation sites will be identified in the future or that unknown contamination, or further contamination beyond that which is currently known, at previously identified sites will be discovered. The discovery of additional environmental exposures at sites that we currently own or operate or at which we formerly operated, or at sites to which we have sent hazardous substances or wastes for treatment, recycling or disposal, could result in us having additional expenditures for environmental remediation in the future and, given the many uncertainties involved in assessing environmental liabilities, we may not have adequately reserved for such liabilities or any reserves we have established may prove to be insufficient.

For each of our Specialty Chemicals and Fine Chemicals segments, production is conducted in a single facility and any significant disruption or delay at a particular facility could have a material adverse effect on our business, financial position and results of operations.

Our Specialty Chemicals segment products are produced at our Iron County, Utah facility and our Fine Chemicals segment products are currently produced at our Rancho Cordova, California facility. Any of these facilities could be disrupted or damaged by fire, floods, earthquakes, power loss, systems failures or similar or other events. Although we

– 43 –

have contingency plans in effect for natural disasters or other catastrophic events, these events could still disrupt our operations. Even though we carry business interruption insurance, we may suffer losses as a result of business interruptions that exceed the coverage available under our insurance policies. A significant disruption at one of our facilities, even on a short-term basis, could impair our ability to produce and ship the particular business segment’s products to market on a timely basis, which could have a material adverse effect on our business, financial position and results of operations.

The release or explosion of dangerous materials used in our business could disrupt our operations and cause us to incur additional costs and liabilities.

Our operations involve the handling, production, storage, and disposal of potentially explosive or hazardous materials and other dangerous chemicals, including materials used in rocket propulsion. Despite our use of specialized facilities to handle dangerous materials and intensive employee training programs, the handling and production of hazardous materials could result in incidents that shut down (on a short-term basis or for longer periods) or otherwise disrupt our manufacturing operations and could cause production delays. Our manufacturing operations could also be the subject of an external or internal event, such as a terrorist attack or external or internal accident, that, despite our security, safety and other precautions, results in a disruption or delay in our operations. It is possible that a release of hazardous materials or other dangerous chemicals from one of our facilities or an explosion could result in death or significant injuries to employees and others. Material property damage to us and third parties could also occur. For example, on May 4, 1988, our former manufacturing and office facilities in Henderson, Nevada were destroyed by a series of massive explosions and associated fires. Extensive property damage occurred both at our facilities and in immediately adjacent areas, the principal damage occurring within a three-mile radius. Production of AP ceased for a 15-month period following that incident. Significant interruptions were also experienced in our other businesses, which occupied the same or adjacent sites. There can be no assurance that another incident would not interrupt some or all of the activities carried on at our current AP manufacturing site. The use of our products in applications by our customers could also result in liability if an explosion, fire or other similarly disruptive event were to occur. Any release or explosion could expose us to adverse publicity or liability for damages or cause production delays, any of which could have a material adverse effect on our reputation and profitability and could cause us to incur additional costs and liabilities.

Disruptions in the supply of key raw materials and difficulties in the supplier qualification process, as well as increases in prices of raw materials, could adversely impact our operations.

Key raw materials used in our operations include sodium chlorate, graphite, ammonia, sodium metal, nitrous oxide, HCFC-123, and hydrochloric acid. We closely monitor sources of supply to assure that adequate raw materials and other supplies and components needed in our manufacturing processes are available. In addition, as a supplier to U.S. government contractors or subcontractors, we are frequently limited to procuring materials and components from sources of supply that can meet rigorous government and/or customer specifications. If a supplier provides us raw materials or other supplies or components that are deficient or defective or if a supplier fails to provide us such materials, supplies or components in a timely manner or at all, we may have limited ability to find appropriate substitutes or otherwise meet required specifications and deadlines. In addition, as business conditions, the U.S. defense budget, and congressional allocations change, suppliers of specialty chemicals and materials sometimes consider dropping or in fact drop low volume items from their product lines, which may require, as it has in the past, qualification of new suppliers for raw materials on key programs. The qualification process may impact our profitability or ability to meet contract deliveries and/or delivery timelines. Moreover, we could experience inventory shortages if we are required to use an alternative supplier on short notice, which also could lead to raw materials being purchased on less favorable terms than we have with our regular suppliers. We are further impacted by the cost of raw materials used in production on fixed-price contracts. The increased cost of natural gas and electricity also has a significant impact on the cost of operating our Specialty Chemicals segment facility.

– 44 –

AFC uses substantial amounts of raw materials in its production processes, in particular chemicals, including specialty and bulk chemicals, which include petroleum-based solvents. Increases in the prices of raw materials which AFC purchases from third party suppliers could adversely impact operating results. In certain cases, the customer either provides some of the raw materials which are used by AFC to produce or manufacture the customer’s products or requires AFC to use a particular or limited number of suppliers for a raw material. Failure to receive raw materials in a timely manner, whether from a third party supplier or a customer, could cause AFC to fail to meet production schedules and adversely impact revenues and operating results. A delay in the arrival of a shipment of raw materials from a third party supplier could have a significant impact on AFC’s ability to meet its contractual commitments to customers. Certain key raw materials are obtained from sources from outside the U.S., including the People’s Republic of China. Factors that can cause delays in the arrival of raw materials include weather or other natural events, political unrest in countries from which raw materials are sourced or through which they are delivered, terrorist attacks or related events in such countries or in the U.S., and work stoppages by suppliers or shippers. In addition, the availability of certain chemicals is subject to DEA quotas.

Prolonged disruptions in the supply of any of our key raw materials, difficulty completing qualification of new sources of supply, implementing use of replacement materials or new sources of supply, or a continuing increase in the prices of raw materials and energy could have a material adverse effect on our operating results, financial condition or cash flows.

Each of our Specialty Chemicals and Fine Chemicals segments may be unable to comply with customer specifications and manufacturing instructions or may experience delays or other problems with existing or new products, which could result in increased costs, losses of sales and potential breach of customer contracts.

Each of our Specialty Chemicals and Fine Chemicals segments produces products that are highly customized, require high levels of precision to manufacture and are subject to exacting customer and other requirements, including strict timing and delivery requirements. For example, our Fine Chemicals segment produces chemical compounds that are difficult to manufacture, including highly energetic and highly toxic materials. These chemical compounds are manufactured to exacting specifications of our customers’ filings with the FDA and other regulatory authorities worldwide. The production of these chemicals requires a high degree of precision and strict adherence to safety and quality standards. Regulatory agencies, such as the FDA and the European Medicines Agency, or EMEA, have regulatory oversight over the production process for many of the products that AFC manufactures for its customers. For controlled substances, compliance with DEA regulations is also required. AFC employs sophisticated and rigorous manufacturing and testing practices to ensure compliance with the FDA’s cGMP guidelines and the International Conference on Harmonization Q7A. Because the chemical compounds produced by AFC are so highly customized, they are also subject to customer acceptance requirements, including strict timing and delivery requirements. If AFC is unable to adhere to the standards required or fails to meet the customer’s timing and delivery requirements, the customer may reject the chemical compounds. In such instances, AFC may also be in breach of its customer’s contract.

Like our Fine Chemicals segment, our Specialty Chemicals segment faces similar production demands and requirements. A significant failure or inability to comply with customer specifications and manufacturing requirements or delays or other problems with existing or new products could result in increased costs, losses of sales and potential breaches of customer contracts, which could affect our operating results and revenues.

Successful commercialization of pharmaceutical products and product line extensions is very difficult and subject to many uncertainties. If a customer is not able to successfully commercialize its products for which AFC produces compounds or if a product is subsequently recalled, then the operating results of AFC may be negatively impacted.

– 45 –

Successful commercialization of pharmaceutical products and product line extensions requires accurate anticipation of market and customer acceptance of particular products, customers’ needs, the sale of competitive products, and emerging technological trends, among other things. Additionally, for successful product development, our customers must complete many complex formulation and analytical testing requirements and timely obtain regulatory approvals from the FDA and other regulatory agencies. When developed, new or reformulated drugs may not exhibit desired characteristics or may not be accepted by the marketplace. Complications can also arise during production scale-up. In addition, a customer’s product that includes ingredients that are manufactured by AFC may be subsequently recalled or withdrawn from the market by the customer. The recall or withdrawal may be for reasons beyond the control of AFC. Moreover, products may encounter unexpected, irresolvable patent conflicts or may not have enforceable intellectual property rights. If the customer is not able to successfully commercialize a product for which AFC produces compounds, or if there is a subsequent recall or withdrawal of a product manufactured by AFC or that includes ingredients manufactured by AFC for its customers, it could have an adverse impact on AFC’s operating results, including its forecasted or actual revenues.

A strike or other work stoppage, or the inability to renew collective bargaining agreements on favorable terms, could have a material adverse effect on the cost structure and operational capabilities of AFC.

As of September 30, 2012, AFC had approximately 162 employees that were covered by collective bargaining or similar agreements. We consider our relationships with our unionized employees to be satisfactory. In July 2010, AFC’s collective bargaining and similar agreements were renegotiated and extended to June 2013. If we are unable to negotiate acceptable new agreements with the union representing these employees upon expiration of the existing contracts, we could experience strikes or work stoppages. Even if AFC is successful in negotiating new agreements, the new agreements could call for higher wages or benefits paid to union members, which would increase AFC’s operating costs and could adversely affect its profitability. If the unionized workers were to engage in a strike or other work stoppage, or other non-unionized operations were to become unionized, AFC could experience a significant disruption of operations at its facilities or higher ongoing labor costs. A strike or other work stoppage in the facilities of any of its major customers or suppliers could also have similar effects on AFC.

The pharmaceutical fine chemicals industry is a capital-intensive industry and if AFC does not have sufficient financial resources to finance the necessary capital expenditures, its business and results of operations may be harmed.

The pharmaceutical fine chemicals industry is a capital-intensive industry. Consequently, AFC’s capital expenditures consume cash from our Fine Chemicals segment and our other operations and may also consume cash from borrowings. Increases in capital expenditures may result in low levels of working capital or require us to finance working capital deficits, and such financing may be costly or even unavailable given on-going conditions of the credit markets in the U.S. Changes in the availability, terms and costs of capital or a reduction in credit rating or outlook could cause our cost of doing business to increase and place us at a competitive disadvantage. These factors could substantially constrain AFC’s growth, increase AFC’s costs and negatively impact its operating results.

We may be subject to potential liability claims for our products or services that could affect our earnings and financial condition and harm our reputation.

We may face potential liability claims based on our products or services in our several lines of business under certain circumstances, and any such claims could result in significant expenses, disrupt sales and affect our reputation and that of our products. For example, a customer’s product may include ingredients that are manufactured by AFC. Although such ingredients are generally made pursuant to specific instructions from our customer and tested using techniques provided by our customer, the customer’s product may, nevertheless, be subsequently recalled or withdrawn from the market by the customer, and the recall or withdrawal may be due in part or wholly to product failures or inadequacies that may or may not be related to the ingredients we manufactured for the customer. In such a case, the recall or withdrawal may result in claims being made against us. Although we seek to reduce our potential liability through measures such as contractual indemnification provisions with customers, we cannot assure you that such measures will be enforced or effective. We could be materially and adversely affected if we were required to pay damages or incur defense costs in

– 46 –

connection with a claim that is outside the scope of the indemnification agreements, if the indemnity, although legally enforceable, is not applicable in accordance with its terms or if our liability exceeds the amount of the applicable indemnification, or if the amount of the indemnification exceeds the financial capacity of our customer. In certain instances, we may have in place product liability insurance coverage, which is generally available in the market, but which may be limited in scope and amount. In other instances, we may have self-insured the risk for any such potential claim. There can be no assurance that our insurance coverage, if available, will be adequate or that insurance coverage will continue to be available on terms acceptable to us. Given the current economic environment, it is also possible that our insurers may not be able to pay on any claims we might bring. Unexpected results could cause us to have financial exposure in these matters in excess of insurance coverage and recorded reserves, requiring us to provide additional reserves to address these liabilities, impacting profits. Moreover, any claim brought against us, even if ultimately found to be insignificant or without merit, could damage our reputation, which, in turn, may impact our business prospects and future results.

Technology innovations in the markets that we serve may create alternatives to our products and result in reduced sales.

Technology innovations to which our current and potential customers might have access could reduce or eliminate their need for our products, which could negatively impact the sale of those products. Our customers constantly attempt to reduce their manufacturing costs and improve product quality, such as by seeking out producers using the latest manufacturing techniques or by producing component products themselves, if outsourcing is perceived to be not cost effective. To continue to succeed, we will need to manufacture and deliver products, and develop better and more efficient means of manufacturing and delivering products, that address evolving customer needs and changes in the market on a timely and cost-effective basis, using the latest and/or most efficient technology available. We may be unable to respond on a timely basis to any or all of the changing needs of our customer base. Separately, our competitors may develop technologies that render our existing technology and products obsolete or uncompetitive. Our competitors may also implement new technologies before we are able to do so, allowing them to provide products at more competitive prices. Technology developed by others in the future could, among other things, require us to write-down obsolete facilities, equipment and technology or require us to make significant capital expenditures in order to stay competitive. Our failure to develop, introduce or enhance products and technologies able to compete with new products and technologies in a timely manner could have an adverse effect on our business, results of operations and financial condition.

We are subject to strong competition in certain industries in which we participate and therefore may not be able to compete successfully.

Other than the sale of AP, for which we are the only North American provider, we face competition in all of the other industries in which we participate. Many of our competitors have financial, technical, production, marketing, research and development and other resources substantially greater than ours. As a result, they may be better able to withstand the effects of periodic economic or business segment downturns. Moreover, barriers to entry, other than capital availability, are low in some of the product segments of our business. Consequently, we may encounter intense bidding for contracts. Capacity additions or technological advances by existing or future competitors may also create greater competition, particularly in pricing. Further, the pharmaceutical fine chemicals market is fragmented and competitive. Pharmaceutical fine chemicals manufacturers generally compete based on their breadth of technology base, research and development and chemical expertise, flexibility and scheduling of manufacturing capabilities, safety record, regulatory compliance history and price. AFC faces increasing competition from pharmaceutical contract manufacturers, in particular competitors located in the People’s Republic of China and India, where facilities, construction and operating costs are significantly less. If AFC is unable to compete successfully, its results of operations may be materially adversely impacted. Furthermore, there is a worldwide over-capacity of the ability to produce sodium azide, which creates significant price competition for that product. Maintaining and improving our competitive position will require continued investment in our existing and potential future customer relationships as well as in our technical, production, and marketing operations. We may be unable to compete successfully with our competitors and our inability to do so could result in a decrease in revenues that we historically have generated from the sale of our products.

Due to the nature of our business, our sales levels may fluctuate causing our quarterly operating results to fluctuate.

Our quarterly and annual sales are affected by a variety of factors that could lead to significant variability in our operating results, including as a result of the actual placement, timing and delivery of orders for new and/or existing products. In our Specialty Chemicals segment, the need for our products is generally based on contractually defined milestones that our customers are bound by and these milestones may fluctuate from quarter to quarter resulting in corresponding sales fluctuations. In our Fine Chemicals segment, some of our products require multiple steps of chemistry, the production of which can span multiple quarterly periods. Revenue is typically recognized after the final step and when the product has been delivered and accepted by the customer. As a result of this multi-quarter process, revenues and related profits can vary from quarter to quarter. Consequently, due to factors inherent in the process by which we sell our products, changes in our operating results may fluctuate from quarter to quarter and could result in volatility in our common stock price.

The inherent volatility of the chemical industry affects our capacity utilization and causes fluctuations in our results of operations.

Our Specialty Chemicals and Fine Chemicals segments are subject to volatility that characterizes the chemical industry generally. Thus, the operating rates at our facilities will impact the comparison of period-to-period results. Different facilities may have differing operating rates from period to period depending on many factors, such as transportation costs and supply and demand for the product produced at the facility during that period. As a result, individual facilities may be operated below or above rated capacities in any period. We may idle a facility for an extended period of time because an oversupply of a certain product or a lack of demand for that product makes production uneconomical. The expenses of the shutdown and restart of facilities may adversely affect quarterly results when these events occur. In addition, a temporary shutdown may become permanent, resulting in a write-down or write-off of the related assets. Moreover, workforce reductions in connection with any short-term or long-term shutdowns, or related cost-cutting measures, could result in an erosion of morale, affect the focus and productivity of our remaining employees, including those directly responsible for revenue generation, and impair our ability to retain and recruit talent, all of which in turn may adversely affect our future results of operations.

A loss of key personnel or highly skilled employees, or the inability to attract and retain such personnel, could disrupt our operations or impede our growth.

Our executive officers are critical to the management and direction of our businesses. Our future success depends, in large part, on our ability to retain these officers and other capable management personnel. From time to time we have entered into employment or similar agreements with our executive officers and we may do so in the future, as competitive needs require. These agreements typically allow the officer to terminate employment with certain levels of severance under particular circumstances, such as a change of control affecting our company. In addition, these agreements generally provide an officer with severance benefits if we terminate the officer without cause. Our inability to attract and retain talented personnel and replace key personnel in a timely fashion could disrupt the operations of the segment affected or our overall operations. Furthermore, our business is very technical and the technological and creative skills of our personnel are essential to establishing and maintaining our competitive advantage. For example, customers often turn to AFC because very few companies have the specialized experience and capabilities and associated personnel required for performing chiral separations, energetic chemistries and projects that require high containment. Our future growth and profitability in part depend upon the knowledge and efforts of our highly skilled employees, including their ability to keep pace with technological changes in the fine chemicals and specialty chemicals industries, as applicable. We compete vigorously with various other firms to recruit these highly skilled employees. Our operations could be disrupted by a shortage of available skilled employees or if we are unable to attract and retain these highly skilled and experienced employees.

– 48 –

We may continue to expand our operations through acquisitions, but the acquisitions could divert management’s attention and expose us to unanticipated liabilities and costs. We may experience difficulties integrating the acquired operations, and we may incur costs relating to acquisitions that are never consummated.

Our business strategy may include growth through future possible acquisitions, in particular in connection with our Fine Chemicals segment. Our future growth is likely to depend, in significant part, on our ability to successfully implement this acquisition strategy. However, our ability to consummate and integrate effectively, any future acquisitions on terms that are favorable to us may be limited by the number of attractive and suitable acquisition targets, internal demands on our resources and our ability to obtain or otherwise facilitate cost-effective financing, especially during difficult and unsettled economic times in the credit market. Any future acquisitions would currently challenge our existing resources. To the extent that we were to effect a new acquisition, if we did not properly meet the increasing expenses and demands on our resources resulting from such future growth, our results could be adversely affected. Our success in integrating newly acquired businesses will depend upon our ability to retain key personnel, avoid diversion of management’s attention from operational matters, integrate general and administrative services and key information processing systems and, where necessary, requalify our customer programs. In addition, future acquisitions could result in the incurrence of additional debt, costs and contingent liabilities. We may also incur costs and divert management’s attention to acquisitions that are never consummated. Integration of acquired operations may take longer, or be more costly or disruptive to our business, than originally anticipated. It is also possible that expected synergies from past or future acquisitions may not materialize.

Although we undertake a diligence investigation of each acquisition target that we pursue, there may be liabilities of the acquired companies or assets that we fail to or are unable to discover during the diligence investigation and for which we, as a successor owner, may be responsible. In connection with acquisitions, we generally seek to minimize the impact of these types of potential liabilities through indemnities and warranties from the seller, which may in some instances be supported by deferring payment of a portion of the purchase price. However, these indemnities and warranties, if obtained, may not fully cover the ultimate actual liabilities due to limitations in scope, amount or duration, financial limitations of the indemnitor or warrantor or other reasons.

We have a substantial amount of debt, and the cost of servicing that debt could adversely affect our ability to take actions, our liquidity or our financial condition.

As of December 31, 2012, we had outstanding debt of approximately $58,875, for which we are required to make principal and interest payments. Subject to the limits contained in some of the agreements governing our outstanding debt, we may incur additional debt in the future or we may refinance some or all of this debt. Our level of debt places significant demands on our cash resources, which could:

• make it more difficult for us to satisfy any other outstanding debt obligations;

• require us to dedicate a substantial portion of our cash flow from operations to payments on our debt, reducing the amount of our cash flow available for working capital, capital expenditures, acquisitions, developing our real estate assets and other general corporate purposes;

• limit our flexibility in planning for, or reacting to, changes in the industries in which we compete;

• place us at a competitive disadvantage compared to our competitors, some of which have lower debt service obligations and greater financial resources than we do;

• limit our ability to borrow additional funds; or

• increase our vulnerability to general adverse economic and industry conditions.

We are obligated to comply with various ongoing covenants in our debt, which could restrict our operations, and if we should fail to satisfy any of these covenants, the payment under our debt could be accelerated, which would negatively impact our liquidity.

– 49 –

We are obligated to comply with various ongoing covenants in our debt, including in certain cases financial covenants, that could restrict our operating activities, and the failure to comply could result in defaults that accelerate the payment under our debt. Our outstanding debt generally contains various affirmative, negative and financial covenants. These covenants include provisions restricting our and our current and future domestic subsidiaries’ ability to, among other things:

• pay dividends, repurchase our stock, or make other restricted payments;

• make certain investments or acquisitions;

• incur additional indebtedness;

• create or permit to exist certain liens;

• enter into certain transactions with affiliates;

• consummate a merger, consolidation or sale of assets;

• change our business; and

• wind up, liquidate, or dissolve our affairs.

Any of the covenants described above may restrict our operations and our ability to pursue potentially advantageous business opportunities. Our failure to comply with these covenants could also result in an event of default that, if not cured or waived, could result in the acceleration of all or a substantial portion of our debt, which would negatively impact our liquidity. In light of our continued working capital requirements and challenging market conditions, there is a risk that we may be unable to continue to comply with one or more of our debt covenants in the future. Such noncompliance could require us to re-negotiate new terms with our lenders which, in all likelihood, would lead to the incurrence of transaction costs and potentially other less favorable terms and conditions being placed upon us, thereby further negatively impacting our liquidity and results of operations.

Significant changes in discount rates, rates of return on pension assets and other factors could affect our estimates of pension obligations, which in turn could affect future funding requirements, related costs and our future financial condition, results of operations and cash flows.

As of September 30, 2012, we had unfunded pension obligations, including the current and non-current portions, of $55,827. The cost of our defined benefit pension plans is recognized through operations over extended periods of time and involves many uncertainties during those periods of time. Our funding policy for our U.S. tax-qualified defined benefit pension plans is to accumulate plan assets that, over the long run, will approximate the present value of projected benefit obligations. Our pension cost is materially affected by the discount rate used to measure pension obligations, the level of plan assets available to fund those obligations at the measurement date and the expected long-term rate of return on plan assets. Changes in these and related factors can affect our estimates of pension obligations. Additionally, significant changes in investment performance or a change in the portfolio mix of invested assets can result in corresponding increases and decreases in the valuation of plan assets or in a change of the expected rate of return on plan assets.

We have unfunded obligations under our U.S. tax-qualified defined benefit pension plans totaling approximately $44,741 on a projected benefit obligation basis as of September 30, 2012. Declines in the value of plan investments or unfavorable changes in law or regulations that govern pension plan funding could materially change the timing and amount of required funding.

Our suspended stockholder rights plan, Restated Certificate of Incorporation, as amended, and Amended and Restated By-laws discourage unsolicited takeover proposals and could prevent stockholders from realizing a premium on their common stock.

We have a stockholder rights plan that, although currently suspended, may have the effect of discouraging unsolicited takeover proposals. The rights issued under the stockholder rights plan would cause substantial dilution to a person or group which attempts to acquire us on terms not approved in advance by our board of directors. In addition, our Restated Certificate of Incorporation, as amended, and Amended and Restated By-laws contain provisions that may discourage unsolicited takeover proposals that stockholders may consider to be in their best interests. These provisions include:

– 50 –

• a classified board of directors;

• the ability of our board of directors to designate the terms of and issue new series of preferred stock;

• advance notice requirements for nominations for election to our board of directors; and

• special voting requirements for the amendment, in certain cases, of our Restated Certificate of Incorporation, as amended, and our Amended and Restated By-laws.

We are also subject to anti-takeover provisions under Delaware law, which could delay or prevent a change of control. Together, our charter provisions, Delaware law and the stockholder rights plan may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our common stock.

Our proprietary and intellectual property rights may be violated, compromised, circumvented or invalidated, which could damage our operations.

We have numerous patents, patent applications, exclusive and non-exclusive licenses to patents, and unpatented trade secret technologies in the U.S. and certain foreign countries. There can be no assurance that the steps taken by us to protect our proprietary and intellectual property rights will be adequate to deter misappropriation of these rights. In addition, independent third parties may develop competitive or superior technologies that could circumvent the future need to use our intellectual property, thereby reducing its value. They may also attempt to invalidate patent rights that we own directly or that we are entitled to exploit through a license. If we are unable to adequately protect and utilize our intellectual property or proprietary rights, our results of operations may be adversely affected.

Our business and operations would be adversely impacted in the event of a failure of our information technology infrastructure.

We rely upon the capacity, reliability and security of our information technology hardware and software infrastructure and our ability to expand and update this infrastructure in response to our changing needs. We are constantly updating our information technology infrastructure. Any failure to manage, expand and update our information technology infrastructure or any failure in the operation of this infrastructure could harm our business.

Despite our implementation of security measures, our systems are vulnerable to damages from computer viruses, natural disasters, unauthorized access and other similar disruptions. Any system failure, accident or security breach could result in disruptions to our operations. To the extent that any disruptions or security breach results in a loss or damage to our data, or in inappropriate disclosure of confidential information, it could harm our business. In addition, we may be required to incur significant costs to protect against damage caused by these disruptions or security breaches in the future.

We are exposed to counterparty risk through our interest rate swap and a counterparty default could adversely affect our financial condition.

We have entered into an interest rate swap with HSBC Bank USA, N.A. (“HSBC”), which subjects us to counterparty risk. The ability of HSBC to perform its obligations under the contract will depend upon a number of factors that are beyond our control and may include, among other things, general economic conditions and the overall financial condition of HSBC. Should HSBC fail to honor its obligations under its agreement with us, we could sustain significant losses which could have an adverse effect on our financial condition, results of operations and cash flows.

– 51 –

Our common stock price may fluctuate substantially, and a stockholder’s investment could decline in value.

The market price of our common stock has been highly volatile during the past several years. For example, during Fiscal 2012, the highest closing sale price for our common stock was $13.47 and the lowest closing sale price for our common stock was $6.85. The realization of any of the risks described in these Risk Factors or other unforeseen risks could have a dramatic and adverse effect on the market price of our common stock. Moreover, the market price of our common stock may fluctuate substantially due to many factors, including:

• actual or anticipated fluctuations in our results of operations;

• events or concerns related to our products or operations or those of our competitors, including public health, environmental and safety concerns related to products and operations;

• material public announcements by us or our competitors;

• changes in government regulations or policies, such as new legislation, laws or regulatory decisions that are adverse to us and/or our products;

• changes in key members of management;

• developments in our industries;

• changes in investors’ acceptable levels of risk;

• trading volume of our common stock; and

• general economic conditions.

In addition, the stock market in general has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to companies’ operating performance. In addition, the global economic environment and potential uncertainty have created significant additional volatility in the United States capital markets. Broad market and industry factors may materially harm the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, stockholder derivative lawsuits and/or securities class action litigation has often been instituted against that company. Such litigation, if instituted against us, and whether with or without merit, could result in substantial costs and divert management’s attention and resources, which could harm our business and financial condition, as well as the market price of our common stock. Additionally, volatility or a lack of positive performance in our stock price may adversely affect our ability to retain key employees or to use our stock to acquire other companies at a time when use of cash or financing for such acquisitions may not be available or in the best interests of our stockholders.

Share-Based Compensation

3 Months Ended

Share-Based Compensation

2. SHARE-BASED COMPENSATION

We account for our share-based compensation arrangements under an accounting standard which requires us to measure the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The fair values of awards are recognized as additional compensation expense, which is classified as operating expenses, proportionately over the vesting period of the awards.

Our share-based compensation arrangements are designed to advance the long-term interests of the Company, including by attracting and retaining employees and directors and aligning their interests with those of our stockholders. The amount, frequency, and terms of share-based awards may vary based on competitive practices, our operating results, government regulations and availability under our equity incentive plans. Depending on the form of the share-based award, new shares of our common stock may be issued upon grant, option exercise or vesting of the award. We maintain three share-based plans, each as discussed below.

The American Pacific Corporation Amended and Restated 2001 Stock Option Plan (the “2001 Plan”) permitted the granting of stock options to employees, officers, directors and consultants.

Options granted under the 2001 Plan generally vested 50% at the grant date and 50% on the one-year anniversary of the grant date, and expire ten years from the date of grant. Under the terms of the 2001 Plan, no options may be granted on or after January 16, 2011, but options previously granted, may extend beyond that date based on the terms of the relevant grant. This plan was approved by our stockholders.

The American Pacific Corporation 2002 Directors Stock Option Plan, as amended and restated (the “2002 Directors Plan”) compensates non-employee directors with stock options granted annually or upon other discretionary events. Options granted under the 2002 Directors Plan prior to September 30, 2007 generally vested 50% at the grant date and 50% on the one-year anniversary of the grant date, and expire ten years from the date of grant. Options granted under the 2002 Directors Plan in November 2007 vested 50% one year from the date of grant and 50% two years from the date of grant, and expire ten years from the date of grant. Under the terms of the 2002 Plan, no options may be granted on or after November 12, 2012, but options previously granted, may extend beyond that date based on the terms of the relevant grant. This plan was approved by our stockholders.

The American Pacific Corporation Amended and Restated 2008 Stock Incentive Plan (the “2008 Plan”) permits the granting of stock options, restricted stock, restricted stock units and stock appreciation rights to employees, directors and consultants. A total of 800,000 shares of common stock are authorized for issuance under the 2008 Plan, provided that no more than 400,000 shares of common stock may be granted pursuant to awards of restricted stock and restricted stock units. Generally, awards granted under the 2008 Plan vest in three equal annual installments beginning on the first anniversary of the grant date, and in the case of option awards, expire ten years from the date of grant. As of December 31, 2012, there were 238,483 shares available for grant under the 2008 Plan. This plan was approved by our stockholders.

Number of vested stock options		506,739
Weighted-average exercise price per share	$	8.60
Aggregate intrinsic value	$	3,497
Weighted-average remaining contractual term in years		5.1

We determine the fair value of stock option awards at their grant date, using a Black-Scholes Option-Pricing model applying the assumptions in the following table. We determine the fair value of restricted stock awards based on the fair market value of our common stock on the grant date. Actual compensation, if any, ultimately realized by optionees may differ significantly from the amount estimated using an option valuation model.

Cash-Settled Restricted Stock Units. Cash-settled restricted stock units (“RSU”) are awards that, if vested, entitle the recipient to a cash payment equal to the fair market value of our common stock for each unit granted. The RSU awards cliff-vest on September 30, 2014, subject to the attainment of financial performance criteria that were established for the two-year period ending September 30, 2014 and continued employment by the recipient. RSUs are accounted for as liability awards, and accordingly, compensation cost is re-measured based on our closing stock price at the end of each reporting period. If we estimate that it is probable that the vesting criteria will be met, then we record compensation expense based on the proportionate share of the total estimated fair value of the award to the requisite service period.

A summary of our RSU activity for the three months ended December 31, 2012 is as follows:

			Weighted-
			Average Grant
	Number of		Date Fair Value
	Units		Per Unit
Outstanding, September 30, 2012		-		-

Interim Basis of Presentation and Accounting Policies

1. INTERIM BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Interim Basis of Presentation.  The accompanying condensed consolidated financial statements of American Pacific Corporation and its subsidiaries (collectively, the “Company”, “we”, “us”, or “our”) are unaudited, but in the opinion of management, include all adjustments, which are of a normal recurring nature, necessary to a fair statement of the results for the interim periods presented. These statements should be read in conjunction with our consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended September 30, 2012. The operating results and cash flows for the three-month period ended December 31, 2012 are not necessarily indicative of the results that will be achieved for the full fiscal year or for future periods.

Accounting Policies and Principles of Consolidation.  A description of our significant accounting policies is included in Note 1 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended September 30, 2012. Our consolidated financial statements include the accounts of American Pacific Corporation and our wholly-owned subsidiaries. All intercompany accounts have been eliminated. We report our results based on a fiscal year which ends on September 30. References to Fiscal years refer to the twelve months ended or ending September 30 of the Fiscal year referenced.

Discontinued Operations.  In May 2012, our board of directors approved and we committed to a plan to sell our Aerospace Equipment segment, which was comprised of Ampac-ISP Corp. and its wholly-owned foreign subsidiaries (“AMPAC-ISP”). We completed the sale of substantially all of the assets of AMPAC-ISP effective August 1, 2012. The divestiture is a strategic shift that allows us to place more focus on the growth and performance of our pharmaceutical-related product lines. Revenues and expenses associated with the Aerospace Equipment segment operations are presented as discontinued operations for all periods presented. (See Note 10).

Use of Estimates.  The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. Judgments and assessments of uncertainties are required in applying our accounting policies in many areas. For example, key assumptions and estimates are particularly important when determining our projected liabilities for pension benefits, useful lives for depreciable and amortizable assets, and deferred tax assets. Other areas in which significant judgment exists include, but are not limited to, costs that may be incurred in connection with environmental matters and the resolution of litigation and other contingencies. Actual results may differ from estimates on which our consolidated financial statements were prepared.

Fair Value Disclosure of Financial Instruments.  The current authoritative guidance on fair value clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value and expands disclosures about the use of fair value measurements. The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 – Significant inputs to the valuation model are unobservable.

We estimate the fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their carrying values due to their short-term nature. We estimate the fair value of our variable-rate term loan as of December 31, 2012 to be approximately equal to its carrying value of $58,875 due to the close proximity of the balance sheet date to the original issuance date of the term loan.

Depreciation and Amortization Expense.  Depreciation and amortization expense, associated with our continuing operations, is classified as follows in our statements of operations:

	Three Months Ended

Total	$	3,310	$	3,682

Bill and Hold Transactions. Some of our fine chemicals products customers have requested that we store materials purchased from us in our facilities (“Bill and Hold” arrangements). The sales value of inventory, subject to Bill and Hold arrangements, at our facilities was $18,217 and $19,346 as of December 31, 2012 and September 30, 2012, respectively.

Recently Issued or Adopted Accounting Standards.  In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, which amends Topic 220, Comprehensive Income. The amendment allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements, and eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. This standard was effective for us beginning on October 1, 2012. This standard changes presentation requirements, and accordingly, the adoption of this standard did not have an impact on our results of operations, financial position or cash flows.

On January 24, 2013, we entered into a floating-to-fixed interest rate swap with an initial notional amount of $58,875 (such notional amount reducing over the life of the arrangement), terminating October 26, 2017, which will effectively convert our floating-rate debt to a fixed rate. Under the terms of the swap, we will pay a fixed rate of approximately 0.775% and we will receive a floating-rate payment tied to the one-month LIBOR. We designated this interest rate swap as a cash flow hedge in accordance with the accounting guidance in ASC Topic 815.

Environmental Matters.

Regulatory Review of Perchlorates.  Our Specialty Chemicals segment manufactures and sells products that contain perchlorates. Currently, perchlorate is on Contaminant Candidate List 3 of the U.S. Environmental Protection Agency (the “EPA”). In February 2011, the EPA announced that it had determined to move forward with the development of a regulation for perchlorates in drinking water, reversing its October 2008 preliminary determination not to promulgate such a regulation. Accordingly, the EPA announced its intention to begin to evaluate the feasibility and affordability of treatment technologies to remove perchlorate and to examine the costs and benefits of potential standards. The EPA has conducted various meetings, as required by the Safe Drinking Water Act, including a meeting of the Science Advisory Board, whose report has not yet been made public. We continue to monitor activities and expect the proposed regulation to be published in February 2013 followed by a 60-day public comment period. The earliest a final regulation is expected to be published is August 2014. Regulatory review and anticipated regulatory actions present general business risk to the Company, but no regulatory proposal of the EPA or any state in which we operate, to date, has been publicly announced that we believe would have a material effect on our results of operations and financial position or that would cause us to significantly modify or curtail our business practices, including our remediation activities discussed below.

Perchlorate Remediation Project in Henderson, Nevada. We commercially manufactured perchlorate chemicals at a facility in Henderson, Nevada (the “AMPAC Henderson Site”) from 1958 until the facility was destroyed in May 1988, after which we relocated our production to a new facility in Iron County, Utah. Kerr-McGee Chemical Corporation (“KMCC”) also operated a perchlorate production facility in Henderson, Nevada (the “KMCC Site”) from 1967 to 1998. In addition, between 1956 and 1967, American Potash operated a perchlorate production facility and, for many years prior to 1956, other entities also manufactured perchlorate chemicals at the KMCC Site. As a result of a longer production history in Henderson, KMCC and its predecessor operations manufactured significantly greater amounts of perchlorate over time than we did at the AMPAC Henderson Site.

In 1997, the Southern Nevada Water Authority (“SNWA”) detected trace amounts of the perchlorate anion in Lake Mead and the Las Vegas Wash. Lake Mead is a source of drinking water for Southern Nevada and areas of Southern California. The Las Vegas Wash flows into Lake Mead from the Las Vegas valley.

In response to this discovery by SNWA, and at the request of the Nevada Division of Environmental Protection (“NDEP”), we engaged in an investigation of groundwater near the AMPAC Henderson Site and down gradient toward the Las Vegas Wash. The investigation and related characterization, which lasted more than six years, employed experts in the field of hydrogeology. This investigation concluded that although there is perchlorate in the groundwater in the vicinity of the AMPAC Henderson Site up to 700 parts per million, perchlorate from this site does not materially impact, if at all, water flowing in the Las Vegas Wash toward Lake Mead. It has been well established, however, by data generated by SNWA and NDEP, that perchlorate from the KMCC Site did impact the Las Vegas Wash and Lake Mead. The Nevada Environmental Response Trust (“NERT”), which is the entity responsible for completing environmental remediation work at the Henderson location as a result of the 2010 settlement of the 2009 bankruptcy of KMCC’s successor, Tronox LLC, operates an above ground perchlorate groundwater remediation facility at their Henderson site. Tronox LLC is currently a tenant of NERT at the property.

Notwithstanding these facts, and at the direction of NDEP and the EPA, we conducted an investigation of remediation technologies for perchlorate in groundwater with the intention of remediating groundwater near the AMPAC Henderson Site. In 2002, we conducted a pilot test and in Fiscal 2005, we submitted a work plan to NDEP for the construction of a remediation facility near the AMPAC Henderson Site. The conditional approval of the work plan by NDEP in our third quarter of Fiscal 2005 allowed us to generate estimated costs for the installation and operation of the remediation facility to address perchlorate at the AMPAC Henderson Site. We commenced construction in July 2005. In December 2006, we began operations of the permanent facility. The location of this facility is several miles, in the direction of groundwater flow, from the AMPAC Henderson Site.

From time to time, we have held discussions with NDEP to formalize our remediation efforts in an agreement that, if executed, would provide more detailed regulatory guidance on environmental characterization and remedies at the AMPAC Henderson Site and vicinity. Typically, such agreements generally cover such matters as the scope of work plans, schedules, deliverables, remedies for non compliance, and reimbursement to the State of Nevada for past and future oversight costs. Discussions regarding a formal agreement are currently active and we anticipate that a formal agreement is likely to be completed during our Fiscal 2013.

Henderson Site Environmental Remediation Reserve.  We accrue for anticipated costs associated with environmental remediation that are probable and estimable. On a quarterly basis, we review our estimates of future costs that could be incurred for remediation activities. In some cases, only a range of reasonably possible costs can be estimated. In establishing our reserves, the most probable estimate is used; otherwise, we accrue the minimum amount of the range.

During Fiscal 2005 and Fiscal 2006, we recorded aggregate charges of $26,000 representing our estimates at the time of the probable costs of our remediation efforts at the AMPAC Henderson Site, including the costs for capital equipment and on-going operating and maintenance (“O&M”).

Late in Fiscal 2009, we gained additional information from groundwater modeling that indicates groundwater emanating from the AMPAC Henderson Site in certain areas in deeper zones (more than 150 feet below ground surface) is moving toward our existing remediation facility at a much slower pace than previously estimated. Utilization of our existing facilities alone, at this slower groundwater pace, could, according to this groundwater model, extend the life of our remediation project to well in excess of fifty years. As a result of this additional data, related model interpretations and consultations with NDEP, we re-evaluated our remediation operations and determined that we should be able to improve the effectiveness of the treatment program and significantly reduce the total project time by expanding the treatment system existing at the time. The expansion includes installation of additional groundwater extraction wells in the deeper, more concentrated areas, construction of an underground pipeline to move extracted groundwater to our treatment facility, and the addition of fluidized bed reactor (“FBR”) bioremediation treatment equipment (the “Expansion Project”) that will enhance, and in some cases replace, primary components of the existing treatment system. In our Fiscal 2009 fourth quarter, we accrued $13,700 as our initial estimate of the capital cost of the Expansion Project and the related estimates of the effects of the enhanced operations on the on-going O&M costs and project life.

Through June 2011, and in cooperation with NDEP, we worked to develop the formal design, engineering and permitting of the Expansion Project. Based on data obtained through that date, which was largely comprised of firm quotations, we determined that significant modifications to our Fiscal 2009 assumptions were required. As a result, in June 2011, we accrued an additional $6,000 for the estimated increase in cost of the capital component of the Expansion Project, offset slightly by reductions in O&M cost estimates. The estimated capital costs of the Expansion Project increased by approximately $6,400. The increase reflected (i) an increase in the capacity of the FBR bioremediation treatment equipment to accommodate technical requirements based on the testing of new extraction wells in the fall of 2010, and (ii) higher than initially anticipated cost associated with the installation of the equipment and construction of the pipeline. Our estimate of total O&M costs was reduced by approximately $400.

In September 2012, we commenced initial operation of the Expansion Project. Related system optimization and other start-up activities will continue into Fiscal 2013. In September 2012, we recorded an additional remediation charge in the amount of $700, which is substantially attributed to the true-up of estimates to the expected final cost of the Expansion Project. Due to uncertainties inherent in making estimates, our estimates of capital and O&M costs may later require significant revision as new facts become available and circumstances change.

The estimated life of the project is a key assumption underlying the accrued estimated cost of our remediation activities. Groundwater modeling and other information regarding the characteristics of the surrounding land and demographics indicate that at our targeted processing rate of 450 gallons per minute for the new groundwater extraction wells (750 gallons per minute in the aggregate with existing wells), the life of the project could range from 5 to 18 years from the date that the Expansion Project was placed in service. Further, the data indicates that within that range, 7 to 14 years is the more likely range. In accordance with generally accepted accounting principles, if no point within the more likely range is considered more likely than another, then estimates should be based on the low end of the range. Accordingly, our accrued remediation cost includes estimated O&M costs through 2019, which is the low end of the likely range of the project life. Groundwater speed, perchlorate concentrations, aquifer characteristics and forecasted groundwater extraction rates will continue to be key factors considered when estimating the life of the project. If additional information becomes available in the future that leads to a different interpretation of the model, thereby dictating a change in equipment and operations, our estimate of the resulting project life could change significantly.

The estimate of the annual O&M cost of the project is a key assumption in our computation of the estimated cost of our remediation activities. To estimate O&M costs, we consider, among other factors, the project scope and historical expense rates to develop assumptions regarding labor, utilities, repairs, maintenance supplies and professional services costs. We estimate average annual O&M costs to be approximately $1,900. If additional information becomes available in the future that is different than information currently available to us and thereby leads us to different conclusions, our estimate of O&M expenses could change significantly.

In addition, certain remediation activities are conducted on public lands under operating permits. In general, these permits may require us to relocate our underground pipeline or equipment to accommodate future public utilities and features and require us to return the land to its original condition at the end of the permit period. If we are required to relocate our underground pipeline or equipment in the future, the costs of such activities would be incremental to our current cost estimates. Estimated costs associated with removal of remediation equipment from the land are not material and are included in our range of estimated costs.

As of December 31, 2012, the aggregate range of anticipated environmental remediation costs was from approximately $10,900 to approximately $34,800. This range represents a significant estimate and is based on the estimable elements of cost for capital and O&M costs, and an estimated remaining operating life of the project through a range from the years 2017 to 2030. As of December 31, 2012, the accrued amount was $14,666, based on an estimated remaining life of the project through the year 2019, or the low end of the more likely range of the expected life of the project. Cost estimates are based on our current assessments of the facility configuration. As we proceed with the project, we have, and may in the future, become aware of elements of the facility configuration that must be changed to meet the targeted operational requirements. Certain of these changes may result in corresponding cost increases. Costs associated with the changes are accrued when a reasonable alternative, or range of alternatives, is identified and the cost of such alternative is estimable. Our estimated reserve for environmental remediation is based on information currently available to us and may be subject to material adjustment upward or downward in future periods as new facts or circumstances may indicate.

A summary of our environmental reserve activity for the three months ended December 31, 2012 is shown below:

Balance, September 30, 2012	$	16,754
Expenditures		(2,088)
Balance, December 31, 2012	$	14,666

AFC Environmental Matters.  The primary operations of our Fine Chemicals segment are located on land leased from Aerojet-General Corporation (“Aerojet”), a wholly-owned subsidiary of GenCorp Inc. (“GenCorp”). The leased land is part of a tract of land owned by Aerojet designated as a “Superfund site” under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (“CERCLA”). The tract of land had been used by Aerojet and affiliated companies to manufacture and test rockets and related equipment since the 1950s. Although the chemicals identified as contaminants on the leased land were not used by Aerojet Fine Chemicals LLC (predecessor in interest to Ampac Fine Chemicals LLC) as part of its operations, CERCLA, among other things, provides for joint and several liability for environmental liabilities including, for example, environmental remediation expenses.

As part of the agreement by which we acquired our Fine Chemicals segment business from GenCorp, an Environmental Indemnity Agreement was entered into whereby GenCorp agreed to indemnify us against any and all environmental costs and liabilities arising out of or resulting from any violation of environmental law prior to the effective date of the sale, or any release of hazardous substances by Aerojet Fine Chemicals LLC, Aerojet or GenCorp on the premises of Ampac Fine Chemicals LLC or Aerojet’s Sacramento site prior to the effective date of the sale.

On November 29, 2005, EPA Region IX provided us with a letter indicating that the EPA does not intend to pursue any clean up or enforcement actions under CERCLA against future lessees of the Aerojet property for existing contamination, provided that the lessees do not contribute to or do not exacerbate existing contamination on or under the Aerojet Superfund site.

Other Matters.  Although we are not currently party to any material pending legal proceedings, we are from time to time subject to claims and lawsuits related to our business operations. We accrue for loss contingencies when a loss is probable and the amount can be reasonably estimated. Legal fees, which can be material in any given period, are expensed as incurred. We believe that current claims or lawsuits against us, individually and in the aggregate, will not result in loss contingencies that will have a material adverse effect on our financial condition, cash flows or results of operations.

Debt

5. DEBT

Our outstanding debt balances consist of the following:

	December 31,		September 30,
	2012		2012
Term Loan, variable-rate interest, due through 2017	$	58,875	$	-
Senior Notes, 9%, due 2015		-		65,000
Capital Leases, due through 2014		16		20
Total Debt		58,891		65,020
Less Current Portion		(4,890)		(16)
Total Long-term Debt	$	54,001	$	65,004

Senior Notes. In February 2007, we issued and sold 9.0% Senior Notes due February 1, 2015 (the “Senior Notes”) with an initial aggregate principal amount of $110,000. The Senior Notes accrued interest at an annual rate of 9.0%, payable semi-annually in February and August. The Senior Notes were guaranteed on a senior unsecured basis by all of our existing and future material U.S. subsidiaries.

In connection with our entering into the Credit Facility (as defined below), on October 26, 2012, a notice of redemption was issued for all remaining outstanding Senior Notes specifying a redemption date of November 25, 2012. The Redemption Price for the Notes was 102.250% of the outstanding principal amount of $65,000, plus accrued and unpaid interest to, but not including, the redemption date. On October 26, 2012, we irrevocably deposited funds with the trustee in an amount equal to the Redemption Price for the Senior Notes and the related indenture was discharged. The transaction resulted in a net loss on debt retirement of $2,835 which includes the call premium of $1,463, the write-off of then unamortized debt issuances costs of $1,251 and other expenses of $121.

ABL Credit Facility. On January 31, 2011, American Pacific Corporation, as borrower, entered into an asset based lending credit agreement (the “ABL Credit Facility”) with Wells Fargo Bank, National Association, as agent and as lender, and certain domestic subsidiaries of the Company, as guarantors, which provided a secured revolving credit facility in an aggregate principal amount of up to $20,000 at any time outstanding with an initial maturity of 90 days prior to the maturity date of the Senior Notes, which was February 1, 2015. The maximum borrowing availability under the ABL Credit Facility was based upon a percentage of our eligible account receivables and eligible inventories. On October 26, 2012, we terminated the ABL Credit Facility.

Credit Facility. On October 26, 2012, we entered into an $85,000 senior secured credit agreement (the “Credit Facility”) by and among American Pacific Corporation, the lenders party thereto (the “Lenders”) and KeyBank National Association, as the swing line lender, issuer of letters of credit under the Credit Facility and as the Administrative Agent of the Lenders. Under the Credit Facility, we (i) obtained a term loan in the aggregate principal amount of $60,000 with an initial maturity in 5 years (the “Term Loan”), and (ii) may obtain revolving loans of up to $25,000 in aggregate principal amount, of which up to $5,000 may be outstanding in connection with the issuance of letters of credit (the “Revolving Facility”). We may prepay and terminate the Credit Facility at any time, without premium or penalty. The Credit Facility contains certain mandatory prepayment provisions which are based upon certain asset sales, equity issuances, incurrence of certain indebtedness and events of loss.

For any loans under the Credit Facility, we elect between two options to determine the annual interest rates applicable to such loans: Base Rate Loans and Eurodollar Loans. These elections can be renewed or changed from time to time during the term of the Credit Facility. The interest rate for an election period is determined as the Base Rate or the Adjusted Eurodollar Rate (each as defined in the Credit Facility), and in each case, plus an applicable margin, which shall range from 0.75% to 1.50% for Base Rate Loans or from 1.75% to 2.50% for Eurodollar Loans, subject to adjustment based on the leverage ratio. Interest payments are due at least quarterly and may be more frequent under certain Eurodollar Loan elections. The Term Loan includes quarterly principal amortization payments which commenced on December 31, 2012. Scheduled Amortization of the Term Loan is $4,500, $6,000, $6,000, $6,000 and $7,500 for each of the five years in the period ending September 30, 2017, respectively. The remaining balance of the Term Loan of $30,000 is due upon maturity.

The Credit Facility is guaranteed by our current and future domestic subsidiaries and is secured by substantially all of our assets and the assets of our current and future domestic subsidiaries, subject to certain exceptions as set forth in the Credit Facility. The Credit Facility contains customary affirmative, negative and financial covenants which, among other things, restrict our ability to:

• pay dividends, repurchase our stock, or make other restricted payments;

• make certain investments or acquisitions;

• incur additional indebtedness;

• create or permit to exist certain liens;

• enter into certain transactions with affiliates;

• consummate a merger, consolidation or sale of assets;

• change our business; and

• wind up, liquidate, or dissolve our affairs.

In each case, the covenants set forth above are subject to customary and negotiated exceptions and exclusions.

The Credit Facility includes two financial covenants that are measured quarterly.

Leverage Ratio.  The Leverage Ratio must be less than or equal to 3.00 to 1.00. The Credit Facility defines the Leverage Ratio as the ratio of Consolidated Total Debt as of the last day of a quarter (“Test Date”) to Consolidated EBITDA for the four consecutive quarters preceding the Test Date, each as defined in the Credit Facility.

Debt Service Coverage Ratio.  The Debt Service Coverage Ratio must be at least 2.00 to 1.00, with increases to 2.25 to 1.00 for the period commencing September 30, 2014 to September 29, 2015, and to 2.50 to 1.00 for the period commencing September 30, 2015 and thereafter. The Credit Facility defines the Debt Service Coverage Ratio as the ratio of Consolidated EBITDA minus Consolidated Capital Expenditures to Scheduled Repayments plus Consolidated Adjusted Interest Expense, each as defined in the Credit Facility.

With respect to these covenant compliance calculations, Consolidated EBITDA, as defined in the Credit Facility (hereinafter, referred to as “Credit Facility EBITDA”), differs from typical EBITDA calculations and our calculation of Adjusted EBITDA, which is used in certain of our public releases and in connection with our incentive compensation plan. The most significant difference in the Credit Facility EBITDA calculation is the inclusion of cash payments for environmental remediation as part of the calculation. The following statements summarize the elements of those definitions that are material to our computations. Consolidated Total Debt generally includes principal amounts outstanding under our Credit Facility, capital leases, drawn amounts for outstanding letters of credit and other indebtedness for borrowed money. Credit Facility EBITDA is generally computed as consolidated net income (loss) plus income tax expense (benefit), interest expense, depreciation and amortization, stock-based compensation expense, and certain non-cash charges and less cash payments for environmental remediation, extraordinary gains and certain other non-cash gains. In accordance with the definitions contained in the Credit Facility, as of December 31, 2012, our Leverage Ratio was 1.34 to 1.00 and our Debt Service Coverage Ratio was 5.63 to 1.00.

The Credit Facility also contains usual and customary events of default (subject to certain threshold amounts and grace periods). If an event of default occurs and is continuing, the Company may be required to repay the obligations under the Credit Facility prior to the Credit Facility’s stated maturity and the related commitments may be terminated.

Debt Issue Costs. In connection with the issuance of the Credit Facility, we incurred debt issuance costs of approximately $1,364, which are capitalized and classified as other assets on our consolidated balance sheets. These costs are being amortized, using the effective interest rate method, as additional interest expense over the term of the Credit Facility.

Letters of Credit. As of December 31, 2012, we had $385 in outstanding standby letters of credit which mature through April 2016. These letters of credit principally secure performance of certain water treatment equipment sold by us. The letters of credit are collateralized by cash on deposit with the issuing bank in the amount of 105% of the outstanding letters of credit. Collateral deposits are classified as other assets on our consolidated balance sheets.

Defined Benefit Plans

9. DEFINED BENEFIT PLANS

Defined Benefit Plan Descriptions.  We maintain three defined benefit pension plans which cover substantially all of our employees who were employed by the Company prior to July 1, 2010: the Amended and Restated American Pacific Corporation Defined Benefit Pension Plan, the Ampac Fine Chemicals LLC Pension Plan for Salaried Employees, and the Ampac Fine Chemicals LLC Pension Plan for Bargaining Unit Employees, each as amended to date. Collectively, these three plans are referred to as the “Pension Plans”. Pension Plan benefits are paid based on an average of earnings, retirement age, and length of service, among other factors. In May 2010, our board of directors approved amendments to our Pension Plans which effectively closed the Pension Plans to participation by any new employees. Retirement benefits for existing U.S. employees and retirees through June 30, 2010 were not affected by this change. Beginning July 1, 2010, new employees began participating solely in one of the Company’s 401(k) plans. In addition, we maintain the American Pacific Corporation Supplemental Executive Retirement Plan, as amended and restated, (the “SERP”) that includes three executive officers and two former executive officers. We use a measurement date of September 30 to account for our Pension Plans and SERP.

Net periodic pension cost consists of the following:

Defined Contribution Plan Descriptions. We maintain two 401(k) plans in which participating employees may make contributions. One covers substantially all employees except bargaining unit employees of our Fine Chemicals segment and the other covers those bargaining unit employees. We make matching contributions for all Fine Chemicals segment employees and, since July 1, 2010, for all eligible new employees.

Contributions and Benefit Payments. For the three months ended December 31, 2012, we contributed $2,391 to the Pension Plans to fund benefit payments and anticipate making approximately $4,313 in additional contributions through September 30, 2013. For the three months ended December 31, 2012, we contributed $132 to the SERP to fund benefit payments and anticipate making approximately $396 in additional contributions through September 30, 2013.

Segment Information

7. SEGMENT INFORMATION

We report our continuing operations in three operating segments: Fine Chemicals, Specialty Chemicals, and Other Businesses. These segments are based upon business units that offer distinct products and services, are operationally managed separately and produce products using different production methods. Segment operating income or loss includes all sales and expenses directly associated with each segment. Environmental remediation charges, corporate general and administrative costs, which consist primarily of executive, investor relations, accounting, human resources and information technology expenses, and interest are not allocated to segment operating results.

Fine Chemicals. Our Fine Chemicals segment includes the operating results of our wholly-owned subsidiaries Ampac Fine Chemicals LLC and AMPAC Fine Chemicals Texas, LLC (collectively, “AFC”). AFC is a custom manufacturer of active pharmaceutical ingredients and registered intermediates for commercial customers in the pharmaceutical industry. AFC operates in compliance with the U.S. Food and Drug Administration’s current Good Manufacturing Practices and the requirements of certain other regulatory agencies such as the European Union’s European Medicines Agency and Japan’s Pharmaceuticals and Medical Devices Agency. AFC also complies with Drug Enforcement Administration requirements related to the manufacture and sale of certain controlled substances. AFC has distinctive competencies and specialized engineering capabilities in performing chiral separations, manufacturing chemical compounds that require high containment, performing energetic chemistries at commercial scale, and manufacturing Schedule II controlled substances.

Specialty Chemicals. Our Specialty Chemicals segment manufactures and sells: (i) perchlorate chemicals, principally ammonium perchlorate, which is the predominant oxidizing agent for solid propellant rockets, booster motors and missiles used in space exploration, commercial satellite transportation and national defense programs, (ii) sodium azide, a chemical used in pharmaceutical manufacturing, and (iii) Halotron^®, a series of clean fire extinguishing agents used in fire extinguishing products ranging from portable fire extinguishers to total flooding systems.

Other Businesses. Our Other Businesses segment contains our water treatment equipment division and real estate activities. Our water treatment equipment business markets, designs, and manufactures electrochemical On Site Hypochlorite Generation, or OSHG, systems. These systems are used in the disinfection of drinking water, control of noxious odors, and the treatment of seawater to prevent the growth of marine organisms in cooling systems. We supply our equipment to municipal, industrial and offshore customers. Our real estate activities are not material.

Our revenues are characterized by individually significant orders and relatively few customers. As a result, in any given reporting period, certain customers may account for more than ten percent of our consolidated revenues. The following table provides disclosure of the percentage of our consolidated revenues from continuing operations attributed to customers that exceed ten percent of the total in each of the given periods.

Income Taxes

8. INCOME TAXES

We review our portfolio of uncertain tax positions and recorded liabilities based on the applicable recognition standards. In this regard, an uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. We classify uncertain tax positions as non-current income tax liabilities unless expected to be settled within one year.

As of both December 31, 2012 and September 30, 2012, our recorded liability for unrecognized tax benefits was $204 and $1,274, of which $204 and $405 would affect our effective tax rate if recognized. In December 2012, the internal revenue service completed its examination of our federal income tax returns for Fiscal years 2009 and 2010 and the related net operating loss carryback claims to Fiscal years 2002, 2003, 2005, 2006, 2007 and 2008 with no significant adjustments. Upon completion of this audit, we released $1,070 of unrecognized tax benefits.

We have no additional significant statutes of limitations that are anticipated to expire in Fiscal 2013. Accordingly, it is reasonably possible that none of the gross liability for unrecognized tax benefits will be reversed during Fiscal 2013.

We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2012 and September 30, 2012, we had accrued $7 and $679, respectively, for the payment of tax-related interest and penalties. For the three months ended December 31, 2012 and 2011, income tax expense (benefit) includes a benefit of $671 and an expense of $13, respectively, for interest and penalties.

We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, we are no longer subject to federal and state examinations before Fiscal 2008.

Discontinued Operations

10. DISCONTINUED OPERATIONS

In May 2012, our board of directors approved and we committed to a plan to sell our Aerospace Equipment segment, which was comprised of Ampac-ISP Corp. and its wholly-owned foreign subsidiaries (“AMPAC-ISP”). The divestiture is a strategic shift that allows us to place more focus on the growth and performance of our pharmaceutical-related product lines.

On June 4, 2012, we entered into an Asset Purchase Agreement with Moog Inc. (“Moog”) (the “Asset Purchase Agreement”), pursuant to which we sold to Moog substantially all of the assets of Ampac-ISP Corp., including all of the equity interests in its foreign subsidiaries (collectively, the “Purchased Assets”). Additionally, Moog assumed certain liabilities related to the operations and the Purchased Assets. The transaction was completed effective August 1, 2012.

Under the terms of the Asset Purchase Agreement, the total consideration was approximately $46,000 (the “Purchase Price”) in cash. In addition, $4,000 of the Purchase Price (the “Escrow Amount”) will be held in an escrow account for 15 months following the closing of the transaction (the “Escrow Period”) and applied towards our indemnification obligations in favor of Moog, if any. The Asset Purchase Agreement provides that we, subject to certain limitations, indemnify Moog for damages and losses incurred or suffered by Moog as a result of, among other things, breaches of our respective representations, warranties and covenants contained in the Asset Purchase Agreement as well as any of the liabilities that we retained. The balance of the Escrow Amount remaining at the end of the Escrow Period shall be released to us. We have accounted for the Escrow Amount as a contingent gain, and accordingly have deferred recognition of the amount until all contingencies have lapsed or been resolved.

Revenues and expenses associated with the operations of AMPAC-ISP are presented as discontinued operations for all periods presented. Summarized financial information for AMPAC-ISP is as follows:
