MOLYCORP, INC.

Notes to Condensed Consolidated Financial Statements

September 30, 2012

(Unaudited)

(1) Basis of Presentation

Molycorp, Inc. (“Molycorp” or the “Company”) is one of the world's leading rare earth products and rare metals companies. Molycorp owns: a world-class rare earth mine and processing facilities at Mountain Pass, California (the "Molycorp Mountain Pass facility"); Molycorp Silmet, one of the largest rare earth oxide ("REO") and rare metal producers in Europe; and the only producer of rare earth alloys in the United States, Molycorp Metals and Alloys ("MMA"). Following the acquisition of Neo Material Technologies, Inc. (formerly referred to as “Neo” and now Molycorp Minerals Canada ULC or “Molycorp Canada”) on June 11, 2012, Molycorp is currently a leading global producer of neodymium-iron-boron (“NdFeB”) magnetic powders (“Neo Powders”), which are used to manufacture bonded NdFeB permanent rare earth magnets, and a leading global manufacturer and distributor of rare earths and zirconium-based engineered materials and applications, and other rare metals and their compounds.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and Regulation S-X promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”). While the December 31, 2011 balance sheet information was derived from the Company’s audited financial statements, for interim periods, GAAP and Regulation S-X do not require all information and related disclosures that are required in the annual financial statements, and all disclosures required by GAAP for annual financial statements have not been included. Therefore, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with Molycorp’s consolidated financial statements and related notes for the year ended December 31, 2011, included in Molycorp's Current Report on Form 8-K filed on August 16, 2012.

The accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, and which, in the opinion of management, are necessary for the fair presentation of Molycorp’s financial position, results of operations and cash flows at September 30, 2012, and for all periods presented. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The preparation of the financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on the Company’s historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ significantly from these estimates under different assumptions and conditions. Significant estimates made by management in the accompanying financial statements include the collectability of accounts receivable, the recoverability of inventory, the useful lives and recoverability of long-lived assets such as property, plant and equipment, intangible assets and investments, capital leases, uncertain tax positions, the fair values of assets acquired and liabilities assumed, including business combinations, and the adequacy of the Company’s asset retirement obligations.

As discussed in Note 15 of Molycorp’s Current Report on Form 8-K filed on August 16, 2012, the Company revised its previously reported results of operations for the third quarter of 2011 to correct an error in the elimination of intercompany sales in that interim period.

In addition, certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications did not affect results of operations.

(2) Capital Requirements

Cash expenditures for the Molycorp Mountain Pass facility plant modernization and expansion efforts, including achieving an annual production capacity of 19,050 mt (“Project Phoenix Phase 1”), the second phase capacity expansion plan to 40,000 mt (“Project Phoenix Phase 2”) and other remaining 2012 capital projects related to operations at the Molycorp Mountain Pass facility are expected to total approximately $170.0 million for the fourth quarter of 2012, and approximately $305.0 million in the first half of 2013, respectively.

9

These estimated cash expenditures described above represent the estimated remaining expenditures for Project Phoenix Phase 1, Project Phoenix Phase 2 and the Company's other remaining 2012 capital projects related to operations at the Molycorp Mountain Pass facility. Including the applicable remaining expenditures, the aggregate cost of Project Phoenix Phase 1 and Project Phoenix Phase 2 is estimated to be approximately $1.25 billion for engineering, procurement and construction (“EPC”), preliminary engineering, insurance, permitting, legal, start-up, commissioning and other costs. All amounts for future capital spending are estimates that include certain discretionary amounts and are subject to change as the projects are further developed. These estimates do not include capitalized interest.

The estimated total costs for Project Phoenix Phase 1 and Project Phoenix Phase 2 include estimated additional EPC expenditures totaling up to $150.0 million for corrections resulting from certain defective engineering work, other engineering, design and scope changes and other cost increases. The Company is pursuing actions to recoup certain costs arising from defective engineering work, including making claims against applicable insurance policies, although there can be no assurance that the Company will be able to recoup all or any portion of such costs. The Company regularly monitors its capital projects to identify opportunities to reduce their total costs.

Anticipated capital expenditures at all other operating facilities of the Company are expected to be approximately $10.0 million during the fourth quarter of 2012. See Note 7.

Other cash requirements include planned contributions to Intermetallics Japan (“IMJ”), the Company's joint venture to manufacture sintered NdFeB permanent rare earth magnets. Molycorp will invest, upon achievement of certain milestones, Japanese Yen (JPY) 2.5 billion in cash, in exchange for ordinary shares of IMJ. The actual remittance amounts will vary depending on the future exchange rate between the U.S. dollar and the Japanese Yen, and the achievement of certain milestones by the joint venture. The Company invested $27.7 million (representing JPY 2.2 billion) to IMJ through September 30, 2012, and plans to invest an additional JPY 300 million (or approximately $3.8 million based on the JPY/ U.S. dollar exchange rate at September 30, 2012) in September 2013. See Note 10. The Company also anticipates making cash investments in other current and new ventures consistent with its mine-to-magnets strategy totaling approximately $8.0 million in the fourth quarter of 2012 and approximately $20.0 million in 2013.

Molycorp expects to fund the remaining capital expenditures under Project Phoenix Phase 1, Project Phoenix Phase 2 and other capital expenditures related to operations at the Molycorp Mountain Pass facility and all other operating facilities, as well as working capital and other cash requirements, with its available cash balances of $436.0 million at September 30, 2012, anticipated future cash flow from operations, and potential proceeds from revolving credit facilities or certain equipment financing that the Company is currently pursuing in its normal process of properly managing its cash and working capital requirements.

There can be no assurance that the Company will be successful in securing access to additional cash proceeds through the revolving credit facilities and lease or loan financing for certain equipment that it is currently pursuing, or other forms of financing on commercially acceptable terms, or at all. Accordingly, if necessary, the Company believes it has the ability to curtail capital expenditures and revise its current business plan to the extent necessary to preserve adequate liquidity sufficient to sustain operations.

(3) Segment Information

In the third quarter of 2012, management reorganized the Company's operations into four new reportable segments to better reflect its primary activities as a global rare earth and magnetics enterprise: Resources; Chemicals and Oxides; Magnetic Materials and Alloys; and Rare Metals. The new composition of the Company's reportable segments is based on a combination of product lines and technologies aligned with its mine-to-magnet strategy.

The Resources segment includes: the Company's operations at its Molycorp Mountain Pass facility where it conducts rare earth minerals extraction to produce rare earth concentrates; REO, including lanthanum, cerium, didymium, neodymium, praseodymium and yttrium; heavy rare earth elements, such as samarium, europium, gadolinium, terbium, dysprosium, and others; didymium rare earth metal; and SorbX^TM (formerly XSORBX), a line of proprietary rare earth-based water treatment products.

The Chemicals and Oxides segment includes: production of REO at the Company's operations in Sillamäe, Estonia; heavy rare earths from the Company's facilities in Jiangyin, Jiangsu Province, China; and production of REO, salts of rare earth elements ("REEs"), zirconium-based engineered materials and mixed rare earth/zirconium oxides from the Company's facilities in Zibo, Shandong Province, China. Rare earths products and zirconium-based engineered products are primarily supplied to

10

the automotive catalyst, electronics, ceramic, clean technology and glass industries.

The Magnetic Materials and Alloys segment includes: the production of Neo Powders through Molycorp's wholly-owned manufacturing facilities in Tianjin, China and Korat, Thailand, under the Molycorp Magnequench brand.

(11) Acquisitions

On June 11, 2012, Molycorp completed the acquisition of all of the outstanding equity of Molycorp Canada's predecessor company pursuant to the terms of an arrangement agreement (the "Arrangement Agreement") for an aggregate purchase price of approximately $1,192.3 million. Pursuant to the Arrangement Agreement, Molycorp Canada's former shareholders elected to receive: (a) cash consideration equal to Canadian dollars ("Cdn") $11.30 per share of Molycorp Canada's predecessor company's common stock; or (b) share consideration of 0.4242 shares of Molycorp common stock or 0.4242 shares (the "Exchangeable Shares") issued by MCP Exchangeco Inc., Molycorp's wholly-owned Canadian subsidiary, which are exchangeable for shares of Molycorp's common stock on a one for one basis, per each share of Molycorp Canada's predecessor company's common stock; or (c) a combination of cash and shares of Molycorp common stock or Exchangeable Shares, all subject to the proration mechanics set forth in the Arrangement Agreement.

The consideration paid to Molycorp Canada's former shareholders was comprised of approximately $908.2 million in cash, exclusive of realized losses on the contingent forward contract to purchase $870.0 million Canadian dollars, accounted for as a separate transaction apart from the business combination, as further discussed in Note 25. Additionally, 13,545,426 shares of Molycorp common stock and 507,203 Exchangeable Shares were issued and collectively valued at $284.1 million based on the closing price of the Company's common stock on the acquisition date in accordance with the relevant accounting guidance. The Exchangeable Shares have no par value.

The following is a preliminary allocation of the Molycorp Canada purchase price (in thousands) and is based on

17

management's preliminary estimates of the fair value of the tangible and intangible assets and liabilities of Molycorp Canada. This valuation is subject to change as the Company obtains additional information on the assets acquired and liabilities assumed during the acquisition measurement period (up to one year from the acquisition date).

	June 11, 2012
Purchase consideration:
Cash consideration	$	908,181
Fair value of Molycorp common stock and Exchangeable Shares issued	284,144
Total purchase consideration	$	1,192,325
Estimated fair values of the assets and liabilities acquired:
Cash and cash equivalents	$	317,169
Accounts receivable	101,470
Inventory	250,989
Prepaid expenses and other current assets	26,893
Property, plant and equipment	70,391
Investments	21,019
Intangibles	491,786
Goodwill	501,571
Other non-current assets	22,859
Accounts payable and accrued expenses	(138,576		)
Debt - current	(255,056		)
Other current liabilities	(29,939		)
Deferred tax liabilities	(158,177		)
Long-term debt	(281		)
Other non-current liabilities	(14,032		)
Non-controlling interests	(15,761		)
Total purchase consideration	$	1,192,325

The fair value of the accounts receivable acquired includes trade receivables of $101.5 million, which are considered to be fully collectible at September 30, 2012.

Molycorp Canada's intangible assets subject to amortization relate to: a) customer relationships of $348.1 million with a weighted average useful life of approximately fifteen years; b) rare earth quotas of $80.3 million with a useful life of approximately 11 years; c) patents of $39.8 million with a weighted average useful life of approximately two years; d) trade name of $15.8 million with a useful life of approximately ten years; and e) other of $7.8 million with a weighted average useful life of approximately twelve years.

Goodwill associated with the Molycorp Canada acquisition arose primarily because of Molycorp Canada's proven leadership in the development, processing, and distribution of technically advanced rare earth products; greater exposure to the world’s largest and fastest-growing rare earths consuming market; deferred tax liabilities and expected synergies that do not qualify for separate recognition. The goodwill is not amortized and is not deductible for tax purposes. As the purchase price allocation is not complete, the Company has not assigned the goodwill to its various reporting units.

The amounts of Molycorp Canada's sales, earnings and earnings per share included in the Company’s condensed consolidated statements of operations since the acquisition date, and the sales, earnings and earnings per share of the combined entity had the acquisition date been January 1, 2011, are as follows:

18

(In thousands, except per share amounts)	Sales		Net Income (Loss)			Net Income (Loss) Attributable To Molycorp			EPS Basic
Actual July 1, 2012 to September 30, 2012 (acquiree)	$	162,764	$	1,118		$	(2,322	)	$	(0.02	)
Actual June 11, 2012 to September 30, 2012 (acquiree)	$	206,397	$	1,165		$	(2,955	)	$	(0.03	)
Unaudited pro forma January 1, 2012 to September 30, 2012 (combined entity)	$	729,469	$	(74,229	)	$	(82,056	)	$	(0.77	)
Unaudited pro forma July 1, 2011 to September 30, 2011 (combined entity)	$	385,889	$	108,386		$	105,947		$	0.94
Unaudited pro forma January 1, 2011 to September 30, 2011 (combined entity)	$	860,707	$	200,951		$	192,300		$	1.69

The unaudited pro forma amounts are not necessarily indicative of the operating results that would have occurred if the Molycorp Canada acquisition had taken place on January 1, 2011.

The unaudited pro forma sales, earnings and earnings per share of the combined entity above are adjusted: a) to eliminate the effect of sales and costs that occurred previous to the business combination between the Company and Molycorp Canada; b) to reflect the net incremental depreciation and amortization expense as a result of the allocation of the purchase price to certain depreciable and amortizable assets with useful lives ranging from two to 30 years; c) the tax effect of unaudited pro forma adjustments using the Molycorp federal, state and international statutory tax rates based on the applicable tax jurisdictions; and d) the estimated net increase of interest expense associated with the issuance of the Company's 10% Senior Secured Notes (as defined below) as part of the acquisition. The unaudited pro forma earnings of the combined entity for the nine months ended September 30, 2012 were also adjusted to exclude $115.2 million of non-recurring direct transaction costs. The weighted average number of shares outstanding utilized in the EPS basic calculation have been adjusted to reflect the additional shares issued pursuant to the acquisition of Molycorp Canada and the related Molibdenos y Metales S.A. equity financing further discussed in Note 16.

For the three and nine months ended September 30, 2012, the Company recognized approximately $0.5 million and $62.0 million, respectively, of transaction costs related to the Molycorp Canada acquisition in the condensed consolidated statements of operations and comprehensive income as follows:

Molycorp Silmet and MMA

The following table summarizes the purchase prices and opening balance sheets for the acquisition of 90.023% controlling interest in Molycorp Silmet on April 1, 2011 and of MMA on April 15, 2011 (in thousands):

Noncontrolling interest	(8,820		)	—
Total purchase consideration	$	81,674		$	17,500

The fair value of the accounts receivable acquired includes trade receivables of $5.0 million for Molycorp Silmet and $4.9 million for MMA. These trade receivables were collected by December 31, 2011. Molycorp Silmet’s intangible assets subject to amortization relate primarily to customer relationships with a weighted average useful life of 15 years. Goodwill associated with the Molycorp Silmet acquisition arose primarily because of the acquired workforce. Goodwill associated with the MMA acquisition arose primarily because of the requirement to record a deferred tax liability for the difference between the assigned values and the tax basis of assets acquired and liabilities assumed at amounts that do not reflect fair value. The goodwill is not amortized and is not deductible for tax purposes. The fair value of the noncontrolling interest in Molycorp Silmet as of April 1, 2011 was valued using a combination of the market approach and income approach.

The pro forma sales, earnings and earnings per share of the Company had both acquisitions occurred on January 1, 2011, are as follows:

(In thousands, except per share amounts)	Sales		Net Income		Net Income Attributable To Molycorp		EPS Basic
Unaudited pro forma January 1, 2011 to September 30, 2011 (combined entity)	$	297,400	$	104,170	$	103,457	$	1.17

The unaudited pro forma amounts are not necessarily indicative of the operating results that would have occurred if these acquisitions had taken place on January 1, 2011.

The 2011 earnings of the combined entity were adjusted to exclude $19.6 million of intercompany sales and $1.8 million of non-recurring acquisition-related costs the Company incurred to acquire Molycorp Silmet and MMA, and to reverse $1.1 million of purchase price variance MMA capitalized during the first quarter of 2011.

Molycorp Silmet

On April 1, 2011, Molycorp acquired 80% of the outstanding shares of Molycorp Silmet from AS Silmet Grupp in exchange for 1,593,419 shares of Molycorp common stock contractually valued at $80.0 million based on the average closing price of the Company’s common stock as reported by The New York Stock Exchange for the 20 consecutive trading days immediately preceding April 1, 2011, the acquisition date.

Generally, the acquisition-date fair value of shares of common stock transferred by the acquirer is the closing price of that stock on the same date adjusted by a discount that a market participant would require as a result of any restrictions on the sale or transferability of the stock. The fair value of common stock of $72.7 million disclosed in the table above is based on the

20

closing price of the Company’s common stock on the acquisition date, net of an estimated discount of 23% that a market participant would require given that issuance of the shares of common stock Molycorp transferred in consideration to AS Silmet Grupp was not registered under the Securities Act of 1933 (the "Securities Act") and such shares were subject to certain lock-up provisions, which limited AS Silmet Grupp’s ability to sell these shares. AS Silmet Grupp retained a 9.977% ownership interest in Molycorp Silmet on the acquisition date; Molycorp acquired the other 10.023% from Treibacher Industrie AG for $9.0 million in cash also on April 1, 2011.

On October 24, 2011, the Company acquired the remaining 9.977% ownership interest in Molycorp Silmet for $10.0 million in cash, which resulted in an adjustment to Additional Paid-In Capital of $0.4 million for the difference between the consideration paid and the carrying value of the noncontrolling interest at October 24, 2011.

The Molycorp Silmet acquisition provided Molycorp with a European base of operations and increased the Company’s yearly REO production capacity by approximately 3,000 mt. Molycorp Silmet sources a portion of rare earth feed stocks for production of its products primarily from the Molycorp Mountain Pass facility. The main focus of Molycorp Silmet is on the production of REO and metals, including didymium metal, a critical component in the manufacture of NdFeB permanent rare earth magnets. Molycorp Silmet’s manufacturing operation is located in Sillamäe, Estonia.

MMA

On April 15, 2011, Molycorp completed the acquisition from Santoku Corporation (“Santoku”) of all the issued and outstanding shares of capital stock of Santoku America, Inc., which is now known as MMA, an Arizona-based corporation, in an all-cash transaction for $17.5 million. The acquisition provided Molycorp with access to certain intellectual properties relative to the development, processing and manufacturing of neodymium and samarium magnet alloy products. As part of the stock purchase agreement, Santoku will provide consulting services to Molycorp for the purpose of maintaining and enhancing the quality of MMA’s products. Molycorp and Santoku also entered into five-year marketing and distribution agreements for the sale and distribution of neodymium and samarium magnet alloy products produced by each party. Additionally, the parties entered into a rare earth products purchase and supply agreement through which MMA will supply Santoku with certain rare earth alloys for a two-year period at prices equal to the feedstock cost plus the applicable product premium as such terms are defined in the agreement.

The balances above for the nine months ended September 30, 2012 and the year ended December 31, 2011, include a short-term portion of $2.1 million and $0.4 million, respectively, which were recorded under other current liabilities. The Company is required to provide the applicable governmental agencies with financial assurances relating to its closure and reclamation obligations. At September 30, 2012, the Company had financial assurance requirements of $28.8 million, which were satisfied with surety bonds placed with California state and regional agencies.

(14) Debt and Capital Lease Obligations

On August 22, 2012, the Company issued of $360.0 million aggregate principal amount of its 6.00% Convertible Senior Notes due 2017 (the “6.00% Convertible Notes”). On August 28, 2012, the underwriters of the 6.00% Convertible Notes exercised their option to purchase an additional $54.0 million aggregate principal amount of the 6.00% Convertible Notes. Total net proceeds from the issuance of the 6.00% Convertible Notes were $395.7 million, after deducting the underwriting discounts and commissions. Certain of the Company's directors, officers and other related parties purchased $6.4 million of the aggregate principal amount of the 6.00% Convertible Notes, for which the Company did not pay any underwriting discounts and commissions.

The 6.00% Convertible Notes are Molycorp's senior unsecured obligations with interest payable semi-annually in arrears on March 1 and September 1 of each year, commencing on March 1, 2013. The 6.00% Convertible Notes will mature on September 1, 2017, unless earlier repurchased, redeemed or converted in accordance with their terms, and will be convertible at any time prior to the second scheduled trading day immediately preceding the maturity date into shares of common stock, cash, or a combination thereof, at Molycorp's election. The conversion rate will initially be 83.333 shares of common stock per $1,000 principal amount of 6.00% Convertible Notes (equivalent to an initial conversion price of approximately $12 per share of common stock), subject to customary adjustments. Molycorp will have the right to redeem the 6.00% Convertible Notes on or after September 1, 2015 if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which Molycorp provides notice of redemption at a redemption price equal to 100% of the principal amount of the 6.00% Convertible Notes to be redeemed, plus accrued and unpaid interest. The 6.00% Convertible Notes rank equal in right of payment to existing and future liabilities that are not expressly subordinated to the 6.00% Convertible Notes, and rank effectively junior to Molycorp's existing and future secured indebtedness.

The Company separately accounts for the liability and equity components of convertible debt instruments, such as the 6.00% Convertible Notes, that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer's economic interest cost. The additional discount on the liability component is amortized to interest cost over the term of the 6.00% Convertible Notes. The effective interest rate on the liability component is 4.6%. The equity component of the 6.00% Convertible Notes is included in the additional paid-in capital section of stockholders' equity on the condensed consolidated balance sheet as of September 30, 2012, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component of the 6.00% Convertible Notes. As of September 30, 2012, Molycorp recognized a liability component related to the 6.00% Convertible Notes of $328.5 million, which includes a cumulative accretion of $1.5 million related to both the underwriting discounts and the additional discount on the liability component, and an equity component of $68.7 million. The amount of interest costs recognized for the three months ended September 30, 2012 relating to both the contractual interest coupon and amortization of the discount on the liability component was $3.8 million, which was substantially capitalized. Transaction costs related to the issuance of the 6.00% Convertible Notes have been allocated to the liability and equity components in proportion to the allocation of proceeds to the components, and accounted for as debt issuance costs (recognized as interest expense over the life of the 6.00% Convertible Notes using the effective interest method) and equity issuance costs (charged against equity), respectively.

22

Concurrently with, and in order to facilitate the offering of the 6.00% Convertible Notes, the Company entered into a share lending agreement with Morgan Stanley Capital Services LLC (“MSCS”), an affiliate of Morgan Stanley & Co. LLC, under which it agreed to loan to MSCS up to a total of 13,800,000 shares of its common stock (the “Borrowed Shares”)during a period beginning on the date the Company entered into the share lending agreement and ending on or about the maturity date of the 6.00% Convertible Notes, or, if earlier, on or about the date as of which all of the 6.00% Convertible Notes cease to be outstanding as a result of redemption, repurchase, conversion or other acquisition for value. MSCS may terminate all or any portion of the Borrowed Shares at any time, and the Company and MSCS may terminate any or all of the outstanding Borrowed Shares upon a default by the other party under the share lending agreement, including certain breaches by MSCS of its representations and warranties, covenants or agreements under the share lending agreement, or the bankruptcy of Molycorp or MSCS. The Company issued a total of 13,800,000 Borrowed Shares between August 22, 2012 and August 23, 2012 and received no proceeds, but only a nominal lending fee from MSCS for the use of these loaned shares, which represented the fair value assigned to it. For corporate law purposes, the Borrowed Shares are issued and outstanding. However, under the share lending agreement, MSCS has agreed: to pay to Molycorp an amount equal to cash dividends, if any, that Molycorp pays on the Borrowed Shares; to pay or deliver, as the case may be, to the Company any other distribution, other than in a liquidation or a reorganization in bankruptcy, that the Company makes on the Borrowed Shares; and not to vote on the Borrowed Shares on any matter submitted to a vote of Molycorp's stockholders. In view of the contractual undertakings of MSCS in the share lending agreement, which have the effect of substantially eliminating the economic dilution that otherwise would result from the issuance of the Borrowed Shares, the Borrowed Shares will not be considered outstanding for the purpose of computing and reporting Molycorp's earnings per share.

             On May 25, 2012, Molycorp issued $650.0 million aggregate principal amount of senior secured notes due 2020 (the "Senior Notes") in an offering exempt from the registration requirements of the Securities Act. Total net proceeds from the issuance of the Senior Notes were $635.4 million after deducting the initial purchasers' discounts. The Senior Notes bear interest at the rate of 10% per year payable on June 1 and December 1 of each year beginning on December 1, 2012. At any time and from time to time prior to June 1, 2016, the Company may redeem any of the Senior Notes at a price equal to 100% of the principal amount thereof plus an applicable make-whole premium and accrued and unpaid interest. At any time and from time to time from and after June 1, 2016, Molycorp may redeem the Senior Notes, in whole or in part, at a redemption price for the Senior Notes plus accrued and unpaid interest, initially at 105% of the principal amount thereof, but gradually declining to 100% of the principal amount thereof. In addition, at any time and from time to time prior to June 1, 2015, the Company may redeem up to 35% of the aggregate principal amount of the Senior Notes with the net cash proceeds of one or more permitted sales of Molycorp’s capital stock at a redemption price (expressed as a percentage of principal amount) of 110% plus accrued and unpaid interest. Upon the occurrence of a change of control, Molycorp will be required to offer to repurchase all of the Senior Notes. The Senior Notes are senior secured obligations of Molycorp and are guaranteed by certain of Molycorp’s domestic subsidiaries ("Guarantors"). The Senior Notes are secured by first-priority security interest on substantially all of the property and assets of the Company and the Guarantors, subject to a number of exceptions as described in the indenture governing the Senior Notes. A substantial portion of the net proceeds from the offering of the Senior Notes was used to fund the cash consideration the Company paid for Molycorp Canada, with the remainder used for general corporate purposes. The Company, the Guarantors and the initial purchasers of the Senior Notes agreed that the Company and the Guarantor will file an exchange offer registration statement with the SEC within 180 days of the May 25, 2012 issuance date, and use their respective commercially reasonable efforts to have it declared effective at the earliest possible time and in any event within 270 days following the issuance date.

As a result of the Molycorp Canada acquisition, the Company assumed $230.0 million principal amount of subordinated unsecured convertible debentures of the predecessor of Molycorp Canada due December 2017 (the “Debentures”) maturing on December 31, 2017. The Debentures bear interest at 5.00% per annum and are convertible at $13.80 per share of Molycorp Canada's predecessor company. As required under the change of control provisions contained in the original underlying indenture, holders of the Debentures had the option to either require the Company to repurchase the Debentures at par plus accrued interest, convert the Debentures into common shares of Molycorp Canada's predecessor company, including a number of additional “make-whole” shares, or hold the Debentures to maturity. In August 2012, holders of $9.4 million aggregate principal amount of Debentures elected to convert, while holders of $217.9 million aggregate principal amount of Debentures elected to early redeem their Debentures for cash plus accrued interest. Under the term of the indenture governing the Debentures, as amended at the time of the Molycorp Canada acquisition, the holders of the Debenture that converted received, at their election and in lieu of receiving shares of Molycorp Canada's predecessor company, the same cash and/or share consideration that was paid to Molycorp Canada's former shareholders in connection with the acquisition of Molycorp Canada, subject to the same pro-ration calculation, as if such holders had converted immediately prior to the acquisition. As a result of the conversion, a total of $8.0 million, including accrued interest, was paid in cash with the remainder converted into 99,723 shares of Molycorp common stock. Total interest cost related to the Debentures for the period from June 12, 2012 to September 30, 2012 was $0.6 million, inclusive of the interest accrued and paid upon the August 2012 repurchase. As of September 30, 2012, $2.7 million principal amount of the Debentures was outstanding.

23

Additional short-term indebtedness was assumed as part of the acquisition of Molycorp Canada totaling $31.5 million, at September 30, 2012, which relates to various bank loans maturing between July 2012 and December 2012 with a weighted average interest rate of approximately 4.22%.

On September 1, 2010, Molycorp and Kern River entered into a firm Transportation Service Agreement ("TSA") under which Kern River agreed to construct and operate facilities necessary to provide natural gas transportation services to the Mountain Pass facility. Under the terms of the TSA, Molycorp agreed to pay Kern River for the cost attributable to the design, permitting, and construction of the delivery facilities through a transportation service charge of approximately $0.4 million per month for ten years. This charge includes reimbursement to Kern River for construction of the delivery facilities and installation, as well as reimbursement and compensation for transportation services. The term of the TSA commenced on June 1, 2012, the date on which Kern River deemed the TSA facilities ready to provide service. The Company accounted for the TSA as a capital lease under the relevant accounting guidance.

The following tables provide a summary of the current and non-current portions of the debt outstanding at September 30, 2012 and December 31, 2011 (in thousands):

Scheduled minimum debt repayments are $31.7 million for the remainder of 2012, $1.4 million in 2013, $1.4 million in 2014, $1.3 million in 2015, $230.7 million in 2016, $417.3 million in 2017 and $650.0 million thereafter.

(15) Income Taxes

The Company’s net loss of $85.9 million for the nine months ended September 30, 2012 included $12.2 million in acquisition-related expense, which is a permanent difference between its loss for financial reporting and tax purposes. Molycorp had net deferred income tax liabilities of $162.3 million at September 30, 2012 primarily related to the purchase accounting adjustment associated with the Molycorp Canada acquisition.

At September 30, 2012, Molycorp determined that it, more likely than not, will realize its deferred tax assets and concluded that no valuation allowance is required. In making this determination, management analyzed, among other things, the Company’s recent history of earnings and cash flows, forecasts of future earnings, and the nature and timing of future deductions and benefits represented by the deferred tax assets and liabilities.

The Company has undistributed earnings for several foreign subsidiaries at September 30, 2012, for which deferred taxes have not been provided. Such earnings are considered indefinitely invested in the foreign subsidiaries. If such earnings were repatriated, additional tax expense may result, although the calculation of such additional taxes is not practicable.

The net tax effect of the elimination in consolidation of intercompany balances and transactions resulted in a deferred

24

charge and income tax payable of $12.5 million at September 30, 2012.

Each quarter the Company evaluates the liability for uncertain tax positions. As a result of the acquisition of Molycorp Canada on June 11, 2012, some uncertain tax positions have decreased due to a lapse of the applicable statute of limitations, which totaled to $1.4 million, and some due to resolution with tax authorities for $13.7 million. These decreases have been recorded as a discrete income tax benefit in the third quarter of 2012. As a result of the statute of limitations that expire in the next 12 months in various jurisdictions, and possible settlements of audit-related issues with taxing authorities in various jurisdictions, the Company believes that it is reasonably possible that the total amount of its net unrecognized income tax benefits will decrease by approximately $4.0 million to $6.0 million in the next 12 months and, if recognized, would affect the Company's effective income tax rate.

(16) Stockholders’ Equity

At September 30, 2012 and December 31, 2011, the Company had 137,957,451 and 83,896,043 shares of common stock outstanding, respectively, and 2,070,000 shares of 5.50% Series A Mandatory Convertible Preferred Stock (“Convertible Preferred Stock”) outstanding.

Concurrently with the issuance of the 6.00% Convertible Notes discussed in Note 14, the Company issued a total of 13,800,000 shares of its common stock at a price to the public of $10.00 per share (the “Primary Shares”) in a separate underwritten public offering. The underwriters received a 6.00% fee in the form of an underwriter's discount for the Primary Shares plus a $1.5 million flat fee to the representative of the underwriters of the Primary Shares. Certain officers, directors and other related parties of the Company participated in offering of the Primary Shares by purchasing 7,090,000 of the total Primary Shares issued, but no underwriting fees were charged to the Company for the purchase by the insiders.

At the same time of the issuance of the 6.00% Convertible Notes and the Primary Shares, and as further discussed in Note 14, the Company entered into a share lending agreement with MSCS, pursuant to which it has agreed to loan to MSCS 13,800,000 shares of common stock. The Company received no proceeds from the Borrowed Shares, but only a nominal lending fee from MSCS for the use of these loaned shares. The Borrowed Shares are issued and outstanding for corporate law purposes. However, based on certain contractual undertakings of MSCS in the share lending agreement that have the effect of substantially eliminating the economic dilution that otherwise would result from the issuance of the Borrowed Shares, the Borrowed Shares will not be considered outstanding for the purpose of computing and reporting Molycorp's earnings per share.

As a result of the conversion of the Debentures, as further discussed in Note 14, a portion of the Debentures tendered was converted into 99,723 shares of Molycorp common stock.

In connection with of the acquisition of Molycorp Canada on June 11, 2012, Molycorp and MCP Exchangeco Inc. issued an aggregate of 13,545,426 shares of common stock and 507,203 Exchangeable Shares, the latter without par value, in consideration for that portion of the purchase price Molycorp paid to Molycorp Canada’s former shareholders who elected to receive shares of Molycorp common stock in addition to or in lieu of cash on the acquisition date. The $284.1 million fair value recorded in additional paid-in capital related to the issuance of acquisition consideration was based on the closing price of the Company’s common stock on June 11, 2012. As of September 30, 2012, 316,860 shares of the Exchangeable Shares had been converted into shares of Molycorp common stock.

On March 8, 2012, Molibdenos y Metales S.A. (“Molymet”), the world’s largest processor of molybdenum and rhenium, headquartered in Santiago, Chile, purchased 12,500,000 shares of the Company’s common stock for $390.1 million, net of stock issuance costs of $0.1 million, at a purchase price of $31.218 per share, which price was determined based on the average daily volume weighted average price of the Company’s common stock on The New York Stock Exchange for the 20 consecutive trading days immediately preceding the date of the agreement, plus a 10% premium. Pursuant to this investment, Molymet acquired the right to nominate a member of the Company’s Board of Directors for so long as Molymet owns a certain percentage of the Company’s common stock.

In February, May and August 2012, the Company declared a cash dividend of $1.375 per share on the Convertible Preferred Stock, respectively. The Company paid $2.8 million of the aggregate dividend in the third quarter of 2012, and a total of $8.5 million during the nine months ended September 30, 2012.

(Loss) income attributable to common stockholders adjusted for effect of dilution	(98,515		)	84,244
Weighted average common shares outstanding—diluted	101,147,638			84,596,676
Diluted (loss) earnings per share	$	(0.97	)	$	1.00

Diluted earnings per share reflect the dilutive impact of potential common stock and unvested restricted shares of common stock in the weighted average number of common shares outstanding during the period, if dilutive. For this purpose, the “treasury stock method” and “if-converted method,” as applicable, are used.

Under the treasury stock method, assumed proceeds upon the exercise of stock options are considered to be used to purchase common stock at the average market price of the shares during the period. Also under the treasury stock method, fixed awards and nonvested shares, such as restricted stock units, are deemed options for purposes of computing diluted earnings per share. At September 30, 2012 and 2011, all potential common stock under the treasury stock method were antidilutive in nature; consequently, the Company did not have any adjustments between earnings per share and diluted earnings per share related to stock options and restricted stock units.

In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be antidilutive. Convertible preferred stock (such as the Convertible Preferred Stock) is antidilutive whenever the amount of the dividend declared in or accumulated for the current period per common share obtainable on conversion, including the deemed dividend in the period from a beneficial conversion feature, exceeds basic earnings per share. The Convertible Preferred Stock was antidilutive at September 30, 2012 and 2011.

Also, under the if-converted method, convertible debt (such as the 3.25% Convertible Notes and the 6.00% Convertible Notes) is antidilutive whenever its interest per common share obtainable on conversion, including any deemed interest from a beneficial conversion feature and nondiscretionary adjustments, net of tax, exceeds basic earnings per share. At September 30, 2012, the 3.25% Convertible Notes and the 6.00% Convertible Notes were antidilutive. The 3.25% Convertible

26

Notes were dilutive for the three and nine months ended September 30, 2011. Therefore, the shares of common stock obtainable on the assumed conversion of the 3.25% Convertible Notes, the interest expense and the amortization of discount, net of income tax, were included in the computation of diluted earnings per share for the corresponding periods.

(18) Stock-Based Compensation

Starting in the first quarter of 2012, the Company granted performance-based restricted stock units ("PBRSUs") and restricted stock units (“RSUs”) to its executive officers, to certain other employees and to some non-employee directors of the Company under its 2010 Equity and Performance Incentive Plan. The RSUs vest on the third anniversary of the grant date. The grant-date fair value of RSUs is determined using the Company’s common stock price on the date of grant and is recognized as stock-based compensation expense on a straight-line basis over the three-year vesting period for the awards that are expected to vest. The PBRSUs vest with respect to between 0% and 150% of the PBRSUs granted to an individual on the basis of the achievement of certain management objectives measured by specified levels of total shareholder return relative to a defined index group over the performance period from January 1, 2012 through December 31, 2014, or upon the occurrence of certain change of control or termination events. The grant-date fair value of PBRSUs is determined using a lattice approach that incorporates a Monte Carlo simulation model. The compensation cost associated with the PBRSUs is recognized straight-line over the performance period for the awards that are expected to vest, even if the market conditions are never satisfied.

From January 1, 2012 through September 30, 2012, the Company issued 46,036 PBRSUs to certain employees, and a total of 235,474 RSUs to certain employees and non-employee directors of the Company.

Some of the RSUs granted to the non-employee directors relate to the grantees' election to convert a portion of their quarterly cash retainer into RSUs. These converted RSUs are fully vested because they relate to services already rendered by the non-employee directors. The same non-employee directors who elected to convert their cash retainer into RSUs, received additional RSUs as matching contributions by the Company equal to 25% of the converted units. The matching RSUs vest on the third anniversary of the grant date.

Also included in the RSUs issued during the first quarter of 2012 were grants related to the election by certain executive officers and other employees of the Company to convert a portion of their 2011 annual cash bonuses into RSUs. These RSUs are fully vested because they relate to services already rendered by the grantees. The conversion of the 2011 annual bonuses into RSUs resulted into an increase in Additional Paid-In Capital of $0.6 million in the first quarter of 2012. The same executive officers and other employees received additional RSUs as matching contribution by the Company equal to 25% of the converted RSUs. The matching RSUs vest on the third anniversary of the grant date.

28

(c) Potential Environmental Obligations

As part of its ongoing remediation efforts at the Molycorp Mountain Pass facility, the Company identified liner defects in three of the onsite evaporation ponds in 2011. These defects led to minor groundwater contamination issues that are limited to a small area directly underneath the evaporation ponds. In order to remediate this issue, the Company will replace the primary lining system and might have to install a groundwater recovery system. The Company estimated the cost of these items at between $2.4 million and $4.6 million, which will be treated as capital expenditures and are included in the purchase obligations table above. The Company is in the process of finalizing the remediation plans with the Regional Water Quality Control Board.

(d) Labor Contract

Certain Molycorp Mountain Pass facility employees are covered by a collective bargaining agreement with the United Steelworkers of America that expires on March 15, 2015. At September 30, 2012, 226 employees, or approximately 60% of the Company’s workforce at the Molycorp Mountain Pass facility, were covered by this collective bargaining agreement.

At September 30, 2012, 172 employees, or approximately 29% of the workforce at the Company’s Molycorp Silmet facility, were unionized employees. The contract with the labor union in Estonia was renewed in February 2012.

(e) Reclamation Surety Bonds

At September 30, 2012, Molycorp had placed $28.8 million of surety bonds with California state and regional agencies to secure its Mountain Pass facility closure and reclamation obligations.

(f) Purported Class Action, Derivative Lawsuits and Investigation

In February 2012, a purported class action lawsuit captioned, Angelo Albano, Individually and on Behalf of All Others Similarly Situated v. Molycorp, Inc., et al., was filed against the Company and certain of its executive officers in the U.S. District Court for the District of Colorado. This federal court action alleges, among other things, that the Company and those officers violated Section 10(b) of the Securities Exchange Act of 1934 in connection with statements relating to its third quarter fiscal 2011 financial results and fourth quarter 2011 production guidance that the Company had filed with or furnished to the SEC, or otherwise made available to the public. In July 2012, the plaintiffs filed an amended consolidated class action complaint against the Company, certain of its officers and directors, certain of its private equity investors, and certain underwriters involved in our public offerings in 2011. The amended complaint alleges, among other things, that some or all of the defendants violated Sections 10(b), 20(a) and 20A of the Securities Exchange Act of 1934 as well as Sections 11, 12(a)(2) and 15 of the Securities Act of 1933. The plaintiffs are seeking unspecified damages and other relief. In October 2012, the defendants filed a motion to dismiss all the claims in the amended complaint. The Company believes the allegations are without merit and that it has valid defenses to such allegations. The Company intends to defend this action vigorously. The Company is unable to provide meaningful quantification of how the final resolution of these claims may impact its future consolidated financial position or results of operations.

Seven stockholder derivative lawsuits have been filed in three different jurisdictions purportedly on behalf of Molycorp, Inc., against certain of its directors and officers, and certain of its private equity investors. These cases have been filed in the Delaware Court of Chancery, the U.S. District Court in Colorado, and the District Court in Arapahoe County, Colorado. They are captioned: Gaines v. Smith et al., Case No. 7282 (Del. Ch. Feb. 12, 2012); Paskowitz v. Smith et al., Case No. 7319 (Del. Ch. Mar. 9, 2012); Wilson v. Smith et al., No. 7395-VCN (Del. Ch. April 4, 2012); Wells v. Smith et al., No. 1:12-cv-00447-WJM (D. Colo. Feb. 21, 2012); Swaggerty v. Smith et al., No. 12-cv-00589-CMA-KLM (D. Colo. Mar. 7, 2012); Clem v. Smith et al., No. 12 CV 392 (Arapahoe Cnty., Colo. Feb. 24, 2012); and Nationwide Consulting, Inc. v. Smith et al., No. 12 CV 448 (Arapahoe Cnty., Colo. Mar. 5, 2012). The Clem and Nationwide cases, which were previously consolidated under the caption Clem v. Smith et al., No. 12 CV 392 (Arapahoe Cnty., Colo.), have been voluntarily dismissed without prejudice. The Wells and Swaggerty cases have both been dismissed without prejudice in favor of the lawsuits proceeding in the Delaware Court of Chancery. As a result, plaintiffs in the Wells and Swaggerty cases filed notices of appeal before the 10th Circuit. The defendants have filed a responsive brief in the 10th Circuit in the Wells and Swaggerty cases. The 10th Circuit case has been fully briefed by the parties.

The derivative cases have been consolidated and are proceeding in the Delaware Court of Chancery. In August 2012, a

29

consolidated amended shareholder derivative complaint was filed with the Delaware Court of Chancery challenging, among other things, certain sales of stock by officers, directors and private equity firms, and certain Molycorp corporate acquisitions during 2011. The amended complaint asserts causes of action for: (1) alleged breaches of fiduciary duty, including the duties of loyalty and due care; (2) alleged breach of fiduciary duty not to trade on or misuse material non-public information; (3) alleged unjust enrichment; and (4) alleged aiding and abetting a breach of fiduciary duty against controlling stockholders. On behalf of Molycorp, the plaintiffs in the derivative actions seek, among other things, monetary damages, restitution, an accounting, and certain changes to corporate governance procedures.

On October 22, 2012, the defendants filed motions to dismiss and motions to stay the derivative case with the Delaware Court of Chancery. Defendants filed their opening briefs in support of the Motions to Stay on November 5, 2012. The parties agreed that all briefing on defendants' Motions to Dismiss should be stayed pending resolution of defendants' Motions to Stay.

In August 2012, the staff of the SEC notified the Company that a formal order of investigation had been issued regarding, among other things, the accuracy of the Company's public disclosures. The Company is cooperating with the staff of the SEC in connection with the investigation. The Company cannot predict the length, scope or results of the investigation or the impact, if any, of the investigation on the Company's results of operations.

The Company made principal payments of $0 million and $3.1 million for the nine month period ended September 30, 2012 and for the year ended December 31, 2011, respectively, under the inventory financing arrangement with Traxys North America LLC (“Traxys and affiliates”), a subsidiary of one of the Company’s stockholders, Traxys S.a.r.l. The outstanding amounts payable to Traxys and affiliates under this arrangement were $0 and $0.9 million reported under Other current liabilities on the condensed consolidated balance sheet at September 30, 2012 and December 31, 2011, respectively. Molycorp also had outstanding amounts payable to Traxys and affiliates under the same arrangement of $0 and $2.8 million reported in Trade accounts payable at September 30, 2012 and December 31, 2011, respectively, associated with product purchased from Traxys and affiliates in 2011. For the three and nine months ended September 30, 2011, the Company made purchases of lanthanum oxide from Traxys and affiliates in the amount of $1.9 million and $6.2 million, respectively.

The Company and Traxys and affiliates also jointly market and sell certain lanthanum oxide, cerium oxide, misch metal and erbium oxide products.

(24) Research and Development

The Company invests significant resources to improve the efficiency of its REO processing operations, the development of new applications for individual rare earth elements and exploratory drilling. These costs consist primarily of salaries, outside labor, material and equipment.

(25) Derivative Instruments

The Company accounts for derivative instruments using the fair value method. GAAP provides for a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.

As a result of the Molycorp Canada acquisition, the Company assumed a liability associated with the put option issued to holders of the noncontrolling interest of Buss & Buss, a business acquired by Molycorp Canada's predecessor company. The Buss & Buss put option is related to a share purchase agreement (“SPA”) between NMT Holding GmbH, a German subsidiary of the Company, and the shareholders of Buss & Buss entered into May 27, 2010 by Molycorp Canada's predecessor company. The SPA includes a call and a put option on shares of the remaining shareholder and his legal successors. If the call option is exercised by the Company, a premium is added to the consideration to purchase the underlying shares in Buss & Buss. If the put option is exercised by the remaining shareholder of Buss & Buss or his legal successors, a discount will reduce the cost basis of the securities sold to the Company. The Company does not account for this derivative as a hedge. The put option had a fair value of $8.8 million at September 30, 2012, recorded as Derivative liability in the condensed consolidated balance sheets. The change in fair value of the put option resulted in an unrealized loss of $0.4 million for the period from June 12, 2012 to September 30, 2012, which was recognized in Interest expense in the condensed consolidated statements of operations and

32

comprehensive income.

The technique Molycorp used to fair value this derivative is the income approach based on a discounted cash flow model. With the exception of the risk free interest rate, the inputs used to fair value this put option are based on unobservable Level 3 inputs based on management's assumptions. These inputs include: equity-risk premium, risk premium, size premium and growth rate. Any reasonably foreseeable changes in assumed levels of unobservable inputs used to fair value this put option would not be expected to have a material impact on the Company's financial position or results of operations.

On March 28, 2012, the Company entered into a contingent forward contract to purchase Canadian dollars with a notional amount of Cdn$870.0 million to manage the foreign currency exposure with respect to its planned acquisition of Molycorp Canada. The Company did not apply hedge accounting to this contingent forward contract. Upon settlement of this derivative on June 11, 2012 (Molycorp Canada acquisition date), the Company recognized a loss of $37.5 million in Other expense. Of this loss, $6.7 million was recognized during the three months ended March 31, 2012 and the remainder during the second quarter of 2012.

(26) Pension

In accordance with the terms of the Arrangement Agreement, Molycorp maintained the terms of the benefit plan for Molycorp Canada’s current and former employees. Molycorp Canada's predecessor company had a defined benefit pension plan (“Pension Plan”), which covered all hourly employees employed as of September 30, 1995, and all hourly employees subsequently hired by Molycorp Canada's predecessor company up to 2003 at its former U.S. manufacturing facility in Anderson, Indiana. A December 31 measurement date is used for the Pension Plan. Molycorp paid $0.2 million as of September 30, 2012 of the estimated total contributions to the Pension Plan for 2012 of $0.2 million.

Molycorp also maintained the terms of Molycorp Canada postretirement medical and life insurance benefits plan for certain employees from the Anderson, Indiana manufacturing facility. The measurement date for this postretirement benefit plan (“PBP”) is December 31.

The actuarial valuation for funding purposes of the Pension Plan and PBP is January 1 of each year. The components of the net periodic pension expense for the period from June 12, 2012 to September 30, 2012 for the Pension Plan and PBP are set forth below (in thousands):

Pension Plan and PBP	For the period from June 12, 2012 to September 30, 2012
Components of net periodic benefit cost:
Service Cost	$	—
Interest cost	90
Expected return on assets	(67		)
Amortization of transition obligation/(asset)	—
Amortization of prior service cost	(1		)

Net periodic benefit cost	$	77

(27) Recent Accounting Pronouncements

In December 2011, the Financial Accounting Standard Board ("FASB") issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05. ASU 2011-12 defers the requirement that companies present reclassification adjustments for each component of Accumulated Other Comprehensive Income (“AOCI”) in both net income and other comprehensive income on the face of the financial statements. Companies will continue to be required to present amounts reclassified out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements. During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income. For the period ended September 30, 2012, the Company did not have any reclassification adjustments for components of AOCI.

33

In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment. Under this updated guidance, an entity will have the option to first assess qualitatively whether it is necessary to perform the current two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is necessary. The update does not change how an entity performs the two-step impairment test under the current guidance. This ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The Company does not expect the adoption of this updated guidance to have a significant impact on its financial statements.

(28) Subsequent Events

Preferred stock dividend

In November 2012, the Company declared a cash dividend of $1.375 per share on the Convertible Preferred Stock to be paid on December 1, 2012 to holders of record at the close of business on November 15, 2012.

we believe that the publications and reports are reliable, we have not independently verified their data.

Overview

We are one of the world's leading rare earth products and rare metals companies that combine a world-class rare earth resource at Mountain Pass, California, with world-leading ultra-high-purity rare earth and rare metal materials processing capabilities. We are vertically integrated across the global rare earth mine-to-magnetics supply chain and we produce custom engineered materials from 13 different rare earths, plus yttrium, with purity levels of up to 6N (99.9999%), and from five other metals (niobium, tantalum, gallium, indium and rhenium) at purity levels of up to 8N (99.999999%).

Rare earth products are critical inputs in many existing and emerging applications including: clean energy technologies, such as hybrid and electric vehicles and wind power turbines; multiple high-tech uses, including mobile devices, fiber optics, lasers and hard disk drives; critical defense applications, such as guidance and control systems and global positioning systems; and advanced water treatment technology for use in industrial, military and outdoor recreation applications. Global demand for rare earth elements, or REEs, is projected by industry analysts to steadily increase both due to continuing growth in existing applications and increased innovation and development of new end uses. We have made significant investments, and expect to continue to invest, in developing technologically advanced applications and proprietary applications for individual REEs.    

The foundation for our “mine-to-magnets” strategy is our Molycorp Mountain Pass facility. Our Molycorp Mountain Pass facility is the largest, most fully developed rare earth mine outside of China and has been producing rare earth products for approximately 60 years. Upon completion of Project Phoenix Phase 1, which we anticipate to occur in the fourth quarter of 2012, we expect our Molycorp Mountain Pass facility to have production cash costs lower than those publicly reported for China by government officials and those reported for other non-Chinese rare earth projects. We are targeting a full planned production rate of approximately 19,050 mt of REO per year in the fourth quarter of 2012, an annual production capacity of 40,000 mt of REO by the end of 2012 and, if customer demand and end-market conditions warrant, a full planned production rate of 40,000 mt of REO per year as early as mid-2013.

We also own several of the leading rare earth processing facilities in the world. Our Molycorp Silmet facility, located in Sillamäe, Estonia, is one of the largest REO and rare metals producers in Europe. Our Molycorp Metals & Alloys, or MMA, facility, located in Tolleson, Arizona, is the only producer of neodymium and samarium magnet alloy and other specialty alloy products in the United States.

We also have created a joint venture with Daido Steel Co., Ltd., or Daido, and Mitsubishi Corporation, or Mitsubishi, in the form of a private company, Intermetallics Japan, or IMJ, to manufacture sintered NdFeB permanent rare earth magnets. The sintered NdFeB magnet manufacturing facility we are constructing in Japan through IMJ remains on schedule for production in early 2013.  The next-generation magnets the joint venture will manufacture do not depend on the use of patents held by other magnet companies and will deliver greater performance with less reliance on dysprosium, a relatively scarce rare earth.  The joint venture has been provisionally awarded a supply agreement for a next-generation electric vehicle with a major automotive manufacturer. As demand for sintered NdFeB magnets continues to rise in the advanced automotive, wind energy, home appliance, industrial motors and other markets, all of the joint venture partners are prepared to invest in additional facilities as needed.

As a result of the Molycorp Canada acquisition in June 2012, we became a leading global producer, processor and developer of NdFeB magnetic powders, or Neo Powders, rare earths and zirconium based engineered materials and applications and other rare metals and their compounds. These innovative products are essential in many of today's high-technology products. Neo Powders are used in the production of high performance, bonded NdFeB permanent magnets, which are found in micro motors, precision motors, sensors and other applications requiring high levels of magnetic strength, flexibility, small size and reduced weight. This acquisition allows us to manufacture also a line of mixed rare earth/zirconium oxides and to reclaim, refine and market high value niche metals and their compounds including gallium, indium and rhenium used in wireless, light emitting diode, or LED, flat panel display, turbine, solar and catalyst applications. Through the Molycorp Canada acquisition we have expanded our operations to include joint ventures and majority owned manufacturing facilities in Jiangyin, Jiangsu Province, China; Zibo, Shandong Province, China; Tianjin, China; Hyeongok Industrial Zone in South Korea; Korat, Thailand; Stade, Germany; Sagard, Germany; Peterborough, Ontario; Napanee, Ontario; Blanding, Utah; and Quapaw, Oklahoma. Additionally, we now conduct research and product development through laboratories in Singapore and Abingdon, United Kingdom.

Our combined workforce of approximately 2,677 employees includes scientists, engineers, chemists, technologists and highly skilled workers in 27 locations across 11 countries.

Material Changes in Results of Operations

The comparability of our operating results during 2012 and 2011 is significantly affected by the Molycorp Canada acquisition on June 11, 2012. This Quarterly Report on Form 10-Q includes the results of Molycorp Canada for the third quarter of 2012 and for the period from June 12, 2012 to September 30, 2012.

Recent Developments

Issuance of 6.00% Convertible Senior Notes due 2017 and Concurrent Offering of Shares of Common Stock

On August 22, 2012, in separate underwritten public offerings, we issued $360 million aggregate principal amount of our 6.00% Convertible Senior Notes due 2017, which we refer to as the 6.00% Convertible Notes, and 12,000,000 shares of our common stock, which we refer to as the Primary Shares, at a price to the public of $10.00 per share. Certain of our officers, directors and other related parties participated in both offerings, but no underwriting fees were paid with respect to the purchases by the insiders. On August 28, 2012, the underwriters of the 6.00% Convertible Notes exercised their option to purchase an additional $54 million aggregate principal amount of the Notes. On August 31, 2012, the underwriters of the Primary Shares exercised their option to purchase an additional 1,800,000 Primary Shares.

Concurrently with the offering of the 6.00% Convertible Notes and the Primary Shares, we entered into a share lending agreement with Morgan Stanley Capital Services LLC, or MSCS, an affiliate of Morgan Stanley & Co. LLC, under which we agreed to loan to MSCS up to 13,800,000 shares of our common stock. We entered into the share lending agreement to facilitate the 6.00% Convertible Notes offering.

Acquisition of Neo Material Technologies Inc. (now known as Molycorp Canada)

On June 11, 2012, we completed the acquisition of all of the outstanding equity of Molycorp Canada's predecessor company pursuant to the terms of an arrangement agreement, which we refer to as the Arrangement Agreement, for an aggregate purchase price of approximately $1,192.3 million. Pursuant to the Arrangement Agreement, Molycorp Canada's former shareholders elected to receive: a) cash consideration equal to Cdn $11.30 per share of the predecessor company's common stock; b) share consideration of 0.4242 shares of Molycorp common stock or 0.4242 shares, which we refer to as the Exchangeable Shares, issued by MCP Exchangeco Inc., our wholly-owned Canadian subsidiary, which are exchangeable for shares of our common stock on a one for one basis, per each share of the predecessor company's common stock; or c) a combination of cash and shares of Molycorp common stock or Exchangeable Shares, all subject to the proration mechanics set forth in the Arrangement Agreement. The consideration paid to Molycorp Canada's former shareholders was comprised of approximately $908.2 million in cash, exclusive of realized losses on the contingent forward contract to purchase Canadian dollars, accounted for a separate transaction apart from the business combination. Additionally, approximately 13,545,426 shares of Molycorp common stock and 507,203 Exchangeable Shares were issued and collectively valued at $284.1 million based on the closing price of the Company's common stock on the acquisition date in accordance with the relevant accounting guidance.

Substantial Repayment of 5.00% Subordinated Unsecured Convertible Debentures

As a result of the Molycorp Canada acquisition, we assumed $230.0 million principal amount of subordinated unsecured convertible debentures due December 31, 2017 (the “Debentures”) that bear interest at an annual rate of 5.00%, as further discussed in Note 14 of the Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q. In August 2012, holders of $9.4 million aggregate principal amount of Debentures elected to convert, while holders of $217.9 million aggregate principal amount of Debentures elected to have their Debentures repurchased for cash plus accrued interest. As a result of the conversion, a total of $8.0 million, including accrued interest, was paid in cash with the remainder converted into 99,723 shares of our common stock. As of September 30, 2012, $2.7 million principal amount of the Debentures was outstanding.

Modernization and Expansion of our Molycorp Mountain Pass Facility

Project Phoenix remains on track to begin producing at our Phase 1 annual rate of 19,050 mt of REO in the fourth quarter of 2012. Additionally, we are on track to achieve an annual production capacity of 40,000 mt of REO by the end of 2012 and, if customer demand and end-market conditions warrant, a full planned production rate of 40,000 mt of REO per year as early as mid-2013.

Project Phoenix construction advanced to the point where the concentrate production circuit became operational. This means that we are now producing rare earth concentrate at our Molycorp Mountain Pass facility with new processes and in new

37

facilities as part of Project Phoenix, including the following:

• Mining of approximately 2,500 metric tons of fresh ore and/or overburden per day, 4 days/week

• Combined Heat & Power, or CHP, Unit

• Crushing / Blending

• First Stage Crack Facility

• Mill & Flotation Circuit

• Cerium Production Unit

• Paste Tailings Facility

• Paste Tailings Permanent Disposal Facility

• Natural Gas Pipeline Lateral

The concentrate being produced with fresh ore at the Molycorp Mountain Pass facility is being processed into separated REOs by our existing separations facility. In addition, concentrates are being shipped to our existing separations facilities at the Molycorp Silmet, and is being stockpiled for eventual processing in our new separations facilities under construction at the Molycorp Mountain Pass facility as part of Project Phoenix.

Our on-site CHP plant began feeding low-cost, high-efficiency electrical power and steam to plants and buildings across the Molycorp Mountain Pass facility in early September 2012. Installing CHP technologies at the Molycorp Mountain Pass facility contributes to several major goals in our business plan: 

• Reducing our Cost of Production - We expect that producing our own electricity, heat, and steam will reduce our cost of power from what we traditionally paid at the Molycorp Mountain Pass facility, of $0.16 cents per kilowatt-hour for non-interruptible service, to less than $0.03 per kilowatt-hour.  This will help us in achieving the lowest cost of production in the industry.

• Maintaining Environmental Superiority - We designed our CHP plant to be extraordinarily energy efficient.  In fact, when fully operational, it is expected to operate above 80% efficiency, with a peak efficiency as much as 85% (Lower Heating Value).  That approaches the maximum practical efficiency for a thermal power generation plant, which we expect will result in less emissions and reduced energy consumption for the same output.  

In mid-September 2012, we achieved two other milestones in the modernization and expansion of our Molycorp Mountain Pass facility: start-up and commissioning operations of our new water treatment plant and our neodymium/praseodymium, or NdPr, separation facility. When fully operational, the Project Phoenix water treatment facility will help us recycle process water that historically was treated as wastewater.  This technology puts us on track to achieving our goals of operating as a near-zero wastewater discharge facility and maintaining environmental superiority in rare earth production at the Molycorp Mountain Pass facility.  This technology also helps drive down our production costs. The start-up and commissioning of our NdPr separation facility is also a very significant milestone to achieving Phase 1 production in the fourth quarter of 2012, and ultimately effectuating Molycorp's vertical integration business model.  Being able to feed NdPr oxide from our high efficiency operations at Mountain Pass to our NdFeB magnet powder and sintered NdFeB magnet manufacturing supply chains is core to our entire mine-to-magnets business strategy.

During the third quarter of 2012, we also started up our new Project Phoenix heavy rare earth concentrate facility at Mountain Pass. This facility will produce heavy rare earth concentrate from freshly mined Mountain Pass ore containing the full range of heavy rare earth elements, such as samarium, europium, gadolinium, terbium, dysprosium, and others.  Because of our acquisition of Molycorp Canada, we have the ability to proceed directly to separation and purification of that concentrate into many high-purity, custom engineered heavy rare earth products.  As our global business expands, we plan to incorporate the high-purity separations technologies now operating in our Jiangyin facility in China to other Molycorp locations, such as Mountain Pass, California; Tolleson, Arizona; and/or Sillamäe, Estonia.

Factors Affecting our Results of Operations

Sales

The quantities we sell are affected by the production capabilities of our rare earth products and rare metals processing facilities, and by a combination of global and regional supply and demand factors, including the production level of certain industries relying on rare earth products, such as the automotive and electronics industries, China REEs export quotas and regulations, prices of REEs, and the demand and sophistication of downstream applications with rare earths content. Sales of our products are also subject to seasonal decreases in the first quarter of each year as companies react to the Chinese New Year holiday shutdown.

Cost of Sales

Our cost of sales includes the processing costs and the cost of certain raw materials we purchased from outside vendors, which we allocated to the products we produced at our operating facilities. In addition, our cost of sales reflects the cost allocated to the inventory we acquired as part of various business acquisitions. Because many of our costs are fixed, as our production increases or decreases, our average cost per metric ton produced decreases or increases, respectively. Primary production costs include direct labor and benefits, chemicals, natural gas, depreciation and amortization, electricity, maintenance, operating supplies and other plant overhead expenses. Our cost of sales may also reflect the write-down of inventory based on current prices for our products, which could materially affect our consolidated net results of operations.

Our most significant variable costs are chemicals, raw materials and electricity. In early September 2012, our on-site CHP plant began feeding low-cost, high efficiency electrical power and steam to plants and buildings across the Molycorp Mountain Pass facility. As a result, natural gas costs will replace third-party electricity costs, which we expect will help us bring our power costs down significantly as further described in the Recent Developments section above. In the future, we also intend to produce more of our chemicals for the Molycorp Mountain Pass facility at an on-site plant, which we expect will reduce our variable chemical costs in that facility.

We expect our labor and benefits costs to increase through at least the remainder of 2012 due to the addition of personnel and contractors required to implement Project Phoenix Phase 1 and Project Phoenix Phase 2. In addition to volume fluctuations, our variable costs, such as electricity, operating supplies and chemicals, are influenced by general economic conditions that are beyond our control.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses consist primarily of personnel and related costs, including stock-based compensation, legal, accounting and other professional fees, occupancy costs and information technology costs. We continue to experience increased selling, general and administrative expenses as we expand our business, including our recent acquisition of Molycorp Canada, operate as a publicly traded company and construct our new facilities at Mountain Pass.

Corporate Development

Our corporate development expenses consist of travel costs, legal and advisory fees that we incur in connection with business acquisitions and other business development activities we pursue as part of our “mine-to-magnets” strategy.

Research and Development

We incur expenses to improve the efficiency of our REO processing operations, develop new applications for individual REEs, research value added rare metals applications and perform exploratory drilling. These expenses, which we anticipate to continue to increase, consist primarily of salaries, outside labor, material and equipment. The acquisition of Molycorp Canada will further bolster our research and development, or R&D, activities with the addition of labs in Singapore and the United Kingdom and process development capabilities at most of the production facilities.

Interest Expenses

We are incurring significantly higher interest costs as a result of issuing additional indebtedness in 2012 to partially finance the Molycorp Canada acquisition, including the repayment of Molycorp Canada's indebtedness, and to fund the remaining capital expenditures under Project Phoenix Phase 1 and Phase 2. The substantial majority of our interest costs is currently capitalized.

39

Income Taxes

We are a Subchapter C corporation and, therefore, are subject to federal and state income taxes on our taxable income. We account for income taxes in accordance with Accounting Standard Codification 740, Income Taxes. This guidance requires the recognition of deferred tax assets and liabilities for the tax effect of temporary differences between the financial statement and tax basis of recorded assets and liabilities at enacted statutory tax rates. This guidance also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The recoverability of deferred tax assets is based on both our historical and anticipated earnings levels and is reviewed each reporting period to determine if any additional valuation allowance is necessary when it is more likely than not that amounts will not be recovered. We have concluded that no valuation allowance was required as of September 30, 2012, and a $2.2 million valuation allowance was required as of September 30, 2011.

We review our deferred tax assets and liabilities each reporting period using the enacted tax rate expected to apply to taxable income for the period in which the deferred tax asset or liability is expected to be realized. The statutory income tax rates that are applied to our current and deferred income tax calculations are significantly impacted by the jurisdictions in which we do business. Changes in jurisdiction income tax rates and apportionment laws will result in changes in the calculation of our current and deferred income taxes. The effects of any changes are recorded in the period of enactment and can increase or decrease the net deferred tax assets and liabilities on the balance sheet.

Environmental

Our operations are subject to numerous and detailed environmental laws, regulations and permits, including those pertaining to employee health and safety, environmental permitting and licensing, air quality standards, greenhouse gases, or GHG, emissions, water usage and pollution, waste management, plant and wildlife protection, handling and disposal of radioactive substances, remediation of soil and groundwater contamination, land use, reclamation and restoration of properties, the discharge of materials into the environment and groundwater quality and availability.

We retain, both within Molycorp and outside Molycorp, the services of reclamation and environmental, health and safety, or EHS, professionals to review our operations and assist with environmental compliance, including with respect to product management, solid and hazardous waste management and disposal, water and air quality, asbestos abatement, drinking water quality, reclamation requirements, radiation control and other EHS issues.

We have spent, and anticipate that we will continue to spend, financial and managerial resources to comply with environmental requirements. For example, we have acquired enough air emission offset credits for both Project Phoenix Phase 1 and Project Phoenix Phase 2. In addition, at our Molycorp Mountain Pass facility during the third quarter of 2012 and 2011, we incurred operating expenses of approximately $1.9 million and $2.5 million, respectively, associated with environmental compliance requirements.

The costs we anticipate to incur as part of our on-going mine reclamation activities at the Molycorp Mountain Pass facility, which we expect to continue throughout closure and post-closure periods of our mining operations, are included in asset retirement obligation disclosure in Note 13 of the Condensed Consolidated Financial Statements, included elsewhere in this Quarterly Report on Form 10-Q.

As part of our continuous efforts to comply with environmental laws and regulations, in 2011 we identified liner defects in three of the onsite evaporation ponds at the Molycorp Mountain Pass facility. This led to minor groundwater contamination issues that are limited to a small area directly underneath the evaporation ponds. In order to remediate this issue, we will replace the primary lining system in two of our evaporation ponds. We estimate the cost of these items to range between $2.4 million and $4.6 million, which will be treated as capital expenditures in 2012. The evaporation ponds in which the lining tears have been detected were substantially drained in 2011 to allow for a detailed inspection of the lining system, and the related costs were recorded as of December 31, 2011. We also estimated that we will incur approximately $17.0 million for wastewater transportation and disposal costs in 2012, primarily for the removal and disposal of any wastewater generated in excess of the existing evaporation capability of all ponds at the Mountain Pass facility, until all facilities currently under construction as part of Project Phoenix Phase 1 and Phase 2 are operational and properly coordinated. We have already incurred $13.0 million of these costs through September 30, 2012.

We cannot predict the impact of new or changed laws, regulations or permit requirements, including the matters discussed below, or changes in the way such laws, regulations or permit requirements are enforced, interpreted or administered. Environmental laws and regulations are complex, change frequently and have tended to become more stringent over time. It is

40

possible that greater than anticipated environmental expenditures will be required in 2012 or in the future, including expenditures as a result of our acquisitions of MMA, Molycorp Silmet and Molycorp Canada. We expect continued government and public emphasis on environmental issues will result in increased future investment for environmental controls at our operations. Additionally, with increased attention paid to emissions of GHGs, including carbon dioxide, current and future regulations are expected to affect our operations. We will continue to monitor developments in these various programs and assess their potential impacts on our operations.

Violations of environmental laws, regulations and permits can result in substantial penalties, court orders to install pollution control equipment, civil and criminal sanctions, permit revocations, facility shutdowns and other sanctions. In addition, environmental laws and regulations may impose joint and several liabilities, without regard to fault, for costs relating to environmental contamination at our facilities or from wastes disposed of at third-party waste facilities. The proposed expansion of our operations is also conditioned upon securing the necessary environmental and other permits and approvals. In certain cases, as a condition to procuring such permits and approvals, we are required to comply with financial assurance requirements. The purpose of these requirements is to assure the government that sufficient company funds will be available for the ultimate closure, post-closure care and/or reclamation at our facilities. We typically obtain bonds as financial assurance for these obligations and, as of September 30, 2012, we had placed a total of $28.8 million of surety bonds with California state and regional agencies. These bonds require annual payment and renewal. In the second quarter of each year, we are required to provide the State of California with an updated estimate of the costs associated with the mine reclamation. This estimate is reviewed and approved by the State of California, after which we are responsible for making any necessary changes to surety bonds placed with the State of California.

As a result of new construction activity at the Molycorp Mountain Pass facility associated with our modernization and expansion project, additional lands have been disturbed since the last mine reclamation cost estimate in 2010, resulting in an increase in the mine reclamation obligation from $3.3 million to $4.1 million. The additional $0.8 million surety amount was placed with the County of San Bernardino and the State of California earlier in 2012. The EPA has announced its intention to establish a new financial assurance program for hardrock mining, extraction and processing facilities under the Federal Comprehensive Environmental Response Compensation and Liability Act or the “Superfund” law, which may require us to establish additional bonds or other sureties. We cannot predict the effect of any such requirements on our operations at this time.

Our Molycorp Sillamäe facility has an Integrated Environmental Permit, which controls its operations in general, and Radiation Practice Licenses for the management of radioactive materials. The Integrated Environmental Permit must be renewed when and if we expand our operations in that facility. The Radiation Practice Licenses are renewed approximately every five years. Some of Radiation Practice Licenses are due for renewal in 2013 and some in 2015.

We are also subject both to Chinese national and local environmental protection regulations, which currently impose a graduated schedule of fees for the discharge of waste substances, require the payment of fines for discharges exceeding the standards, and provide for the closure of any facility that fails to comply with orders requiring it to cease or remedy certain activities causing environmental damage. Our Chinese joint ventures, Jiangyin Jia Hua Advanced Material Resources Co., Ltd., or Jiangyin, and Zibo Jia Hua Advanced Material Resources Co., Ltd., or Zibo, produce waste water from their solvent extraction processes. In the case of Jiangyin, its expansion in 1995 included an upgrading of its waste water processing and treatment procedures, as a result of which its waste water passes all environmental requirements. Jiangyin pays an agreed fee once a year for the discharge of waste waters. In the case of Zibo, the plant was designed to make use of waste water discharge facilities of an adjacent petrochemical complex, which has a variable monthly charge based on usage. Zibo is also obliged to pay a monthly environmental administration fee to the municipal government of Linzi. Waste water has met the requirements set by local authorities for all environmental standards. Both Jiangyin and Zibo were inspected in 2012 as part of an environmental audit and have received the Chinese Ministry of Environmental Protection's approval for compliance with applicable environmental laws. However, there is no assurance that Chinese national or local authorities will not impose additional regulations which would require additional expenditures that may have a material adverse effect on the profitability of the joint ventures.

As part of the recycling of gallium, indium, and rhenium scrap into saleable metal, a significant degree of waste material is generated during the leaching and ion-exchange-barren process. We have adequate procedures in place to ensure that waste generated from these processes are appropriately contained and disposed of in a safe and responsible manner. Our operations in Ontario, Canada are subject to provincial regulation under the Ontario Ministry of Environment and must periodically submit documentation to validate the waste disposal process throughout the year.

Discussion and Analysis of our Reportable Segments

In the third quarter of 2012, we reorganized our operations into four new reportable segments to better reflect our primary activities as a global rare earths and magnetics producer: Resources; Chemicals and Oxides; Magnetic Materials and Alloys; and Rare Metals. The new composition of our reportable segments is based on a combination of product lines and technologies that align with our mine-to-magnet strategy. See Note 3 of the Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for further details.

The following analysis presents operating results on a gross basis (i.e., before intercompany eliminations). We believe this presentation provides a better understanding of the performance of each reportable segment in terms of contribution to our vertically integrated operations. Some of the information for the nine months ended September 30, 2012 is actually for the period from June 12, 2012 (the beginning of the reporting period of Molycorp Canada) through September 30, 2012.

Resources

Sales from our Resources segment were $20.9 million and $84.1 million for the three and nine months ended September 30, 2012, respectively, as compared to sales of $124.9 million and $227.4 million for the three and nine months ended September 30, 2011, respectively. In the third quarter of 2012, this segment sold 835 mt of products at an average sales price, or ASP, of $25.02 per kilogram (on a REO basis), as compared to 1,002 mt at an ASP of $124.65 per kilogram for the corresponding period in 2011. For the nine months ended September 30, 2012 and 2011, Resources sold 2,032 mt at an ASP of $41.41 per kilogram, and 2,685 mt of products at an ASP of $84.69 per kilogram, respectively.

The decrease in volume shipped during the three and nine months ended September 30, 2012 as compared to the corresponding prior periods, was primarily attributable to limited Bastnasite feedstock due to the new mill coming online at the same time the last of the historical stockpiles were drawn down.

Prices for the segment's primary products (cerium, lanthanum, neodymium and praseodymium) have also significantly decreased, as compared to the corresponding periods in 2011, due to premiums placed on Chinese export quotas in 2010 combined with the unwinding of speculative purchases that drove prices for virtually all rare earth elements to a historical peak in July 2011. Beginning in the second quarter of 2012, prices for most rare earth elements have stabilized or declined at a slower pace than earlier in the year. We believe this trend may continue for the remainder of 2012, although there can be no assurance.

Aggregate production volume at our Resources segment was 565 mt and 1,851 mt for the three and nine months ended September 30, 2012, respectively, compared to 739 mt and 2,052 mt for the three and nine months ended September 30, 2011, respectively. We expensed $2.2 million and $7.5 million during the three and nine months ended September 30, 2012 of production-related costs that would have otherwise been charged to inventory if we maintained normal production levels during these periods. This compares to expensing of abnormal production-related costs of $0.8 million and $4.3 million during the three and nine months ended September 30, 2011. However, as we complete and begin to commercialize Project Phoenix Phase 1, we expect to attain increased production levels in future periods.

We recognized a $11.3 million and $20.9 million of total inventory write-down to net realizable value for the three and nine months ended September 30, 2012 as compared to $0 and $0.6 million for the corresponding periods in 2011, respectively.

Variable production costs in this segment were affected by rising prices of chemicals and other raw materials used in our REO production, primarily during the separation process. However, we intend to produce more of our chemicals for our Molycorp Mountain Pass facility at an on-site plant in the near future, which we expect to significantly reduce our variable chemical costs for the segment. Given the lower level of production attained in the current quarter-to-date and year-to-date periods, as compared to the corresponding prior periods, labor cost increases also had a slightly negative effect on the results of operations for this segment. As of September 30, 2012, we had a total of 365 employees at our Molycorp Mountain Pass facility, as compared to 171 employees as of September 30, 2011. Staffing increases are directly related to the ramp up in employees needed to run the larger production facilities, which are in the process of coming online. In addition, the annual wage increase required under our union contract took effect in January 2012 for approximately 60% of our employees at Mountain Pass.

Chemicals and Oxides

Comparative results for the Chemicals and Oxides segment were affected by the addition to our product mix of REO, salts of REEs, zirconium-based engineered materials and mixed rare earth/zirconium oxides from the Molycorp Canada acquisition on June 11, 2012, and REO production from our operations in Sillamäe, Estonia as a result of our acquisition of Molycorp Silmet on April 1, 2011. This segment did not have sales prior to April 1, 2011.

Chemicals and Oxides' sales were $99.4 million on volume of 1,933 mt and $149.7 million on volume of 2,901 mt for the three and nine months ended September 30, 2012, respectively. This compares to sales for this segment of $22.6 million on volume of 384 mt and $41.7 million on volume of 888 mt for the three and nine months ended September 30, 2011, respectively. ASP was $51.41 per kilogram and $51.59 per kilogram for the three and nine months ended September 30, 2012, respectively, as compared to $58.79 per kilogram and $46.95 per kilogram for the corresponding periods in 2011, respectively.

The segment's operating income for the third quarter of 2012 and year-to-date September 30, 2012 was negatively affected by the release of inventory that was stepped-up in value in conjunction with the Molycorp Canada acquisition, and by the write-down of inventory to net realizable value. These adjustments, in the aggregate, totaled to $15.9 million for the three and $23.7 million for the nine months ended September 30, 2012, respectively. This compares to an increase in cost of sales of $10.2 million for the corresponding periods in 2011 from the release of inventory that was stepped-up in value in conjunction the Molycorp Silmet acquisition in April 2011.

45

Main drivers of the period-over-period decrease in ASP was the change in product mix combined with the same REE market's factors that affected realized prices in our Resources segment. Given the current global economic environment, customers in all market segments we serve have been monitoring closely and, in some instances, reducing their inventory levels. However, during the third quarter of 2012 we have seen signs that our major customers are getting back to desired inventory levels, particularly in some markets. For example, demand for our mixed REO for automotive catalyst applications was positive during the third quarter of 2012. As a result, we plan to add capacity for the Chemicals and Oxide segment in 2013 in order to support anticipated growth in this area where we continue to qualify new products with all our major customers. Moreover, our recently acquired operations in Jiangyin, China and Zibo, China, which represent a significant portion of this segment's activity, remain focused on high purity and sophisticated downstream rare earth products. In the third quarter of 2012, Zibo passed the final phase of the Chinese environmental inspection process and we now have full access to our export quotas at both Zibo and Jiangyin for the remainder of 2012.

Magnetic Materials and Alloys

Comparative results for the Magnetic Materials and Alloys segment were affected by the inclusion of Neo Powders from the Molycorp Canada acquisition on June 11, 2012, and neodymium and samarium magnet alloy and other specialty alloy products from the MMA acquisition we completed on April 15, 2011. This segment did not have sales prior to April 15, 2011.

Magnetic Materials and Alloys' sales were $74.8 million on volume of 1,527 mt and $125.3 million on volume of 1,959 mt for the three and nine months ended September 30, 2012, respectively. This compares to sales of $14.4 million on volume of 226 mt and $24.7 million on volume of 427 mt for the three and nine months ended September 30, 2011, respectively. ASP was $48.98 per kilogram and $63.95 per kilogram for the three and nine months ended September 30, 2012, respectively, as compared to $63.93 per kilogram and $57.84 per kilogram for the corresponding periods in 2011, respectively. The price for neodymium, the primary determinant of the price for Neo Powders, which currently account for a larger portion of the volume we sell in this segment, fell by approximately 11% during the third quarter of 2012. Therefore, based on our current pricing methodology, prices for Neo Powders were adjusted accordingly.

The anticipation of falling Neo Powders price generally results in very conservative purchasing patterns by our customers. To the extent possible, purchases of Neo Powders are delayed until the month when the price is anticipated to be lower. This has caused inventory levels to fall to very low levels throughout the supply chain and has impacted volumes shipped. However, shipment for high performance Neo Powders improved, as new applications business - generally replacing standard sintered magnets - grew in the home appliance industry.

During the third quarter of 2012, the operating income of the Magnetic Materials and Alloys segment was impacted by increased cost of sales related to purchase accounting adjustments to the inventory acquired as part of the Molycorp Canada acquisition, and by the write-down of inventory to net realizable value. These adjustments were nominal for the three and nine months ended September 30, 2012 and for the corresponding periods in 2011, respectively.

Rare Metals

Comparative results for the Rare Metals segment were affected by the addition to our product mix of gallium, indium and rhenium from the Molycorp Canada acquisition on June 11, 2012, and niobium and tantalum from our acquisition of Molycorp Silmet on April 1, 2011. This segment did not have sales prior to April 1, 2011.

Sales from our Rare Metals segment were $25.8 million and $57.1 million for the three and nine months ended September 30, 2012, respectively, as compared to sales of $13.3 million and $26.9 million for the three and nine months ended September 30, 2011, respectively. In the third quarter of 2012, this segment sold 96 mt of products at an ASP of $269.22 per kilogram, as compared to 88 mt at an ASP of $151.50 per kilogram for the corresponding period in 2011. For the nine months ended September 30, 2012 and 2011, Rare Metals sold 265 mt and 167 mt of products, respectively, at an ASP of $215.30 per kilogram and $160.82 per kilogram, respectively.

Similarly to the other segments, write-down of inventory to net realizable value had a negative impact to the operating income of the Rare Metals segment. These adjustments decreased operating income by $6.2 million and $6.3 million during the three and nine months ended September 30, 2012. There were no material adjustments to cost of sales for the corresponding prior year periods in this segment.

46

Selling, General and Administrative Expenses

Our consolidated selling, general and administrative expenses, including stock-based compensation, were $31.5 million and $78.7 million for the three and nine months ended September 30, 2012, respectively, as compared to $12.2 million and $31.5 million for the three and nine months ended September 30, 2011, respectively. A large portion of the quarter-over-quarter increase was attributable to higher personnel and related costs stemming from our recent acquisition of Molycorp Canada, higher information technology costs associated with on-going improvements and expansion of our Enterprise Resource Planning system, and larger start-up costs related to the construction of our Molycorp Mountain Pass facility. The increase from the nine months ended September 30, 2011 to the same period in 2012 was substantially driven by the same factors describe above for the quarter-over-quarter change.

Corporate Development

Corporate development expenses were $1.1 million and $19.4 million for the three and nine months ended September 30, 2012, respectively, as compared to $0.6 million and $3.9 million for the three and nine months ended September 30, 2011, respectively. This significant increase during the nine months ended September 30, 2012 over the corresponding period in 2011 was primarily related to the costs we incurred in connection with the Molycorp Canada acquisition in June 2012. The quarter-over-quarter increase was due to other business development activities.

Depreciation, Amortization and Accretion

Consolidated depreciation and amortization expenses related to production were $10.6 million and $19.1 million for the three and nine months ended September 30, 2012, respectively, as compared to $5.1 million and $9.6 million for the three and nine months ended September 30, 2011, respectively. The historical quarter-over-quarter and year-to-date change was primarily related to the addition of fixed assets in conjunction with the Molycorp Canada acquisition.

Consolidated depreciation, amortization and accretion expenses unrelated to production were $9.7 million and $12.4 million for the three and nine months ended September 30, 2012, respectively, as compared to $0.5 million and $1.4 million for the three and nine months ended September 30, 2011, respectively. The increase in both comparative periods was mainly due to the addition of approximately $492.0 million in amortizable intangible assets acquired in connection with the Molycorp Canada acquisition.

Research and Development

Consolidated research and development expenses were $8.9 million and $18.6 million for the three and nine months ended September 30, 2012, respectively, as compared to $2.1 million and $5.2 million for the three and nine months ended September 30, 2011, respectively. The quarterly and year-to-date period over period increase was attributable primarily to our efforts to improve the efficiency of our REO processing operations, to develop new applications for individual REEs, research value added rare metals applications, and perform exploratory drilling. These expenses, which we anticipate to continue to increase in the foreseeable future, consist primarily of salaries, outside labor, material and equipment.

Interest Expense

Interest expense related to all our long-term indebtedness was substantially capitalized through the third quarter of 2012. The larger interest expense we incurred for the three and nine months ended September 30, 2012, as compared to the corresponding periods in 2011, related primarily to the payment of a commitment fee of approximately $7.9 million for a bridge loan we secured with a financial institution prior to the issuance in May 2012 of $650.0 million aggregate principal amount of 10% senior secured notes due 2020, which we refer to as our Senior Notes, and $1.7 million of interest accrued that we paid upon the repurchase of the majority of the $230.0 million aggregate principal amount of Debentures in August 2012. See Note 14 to the Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for further detail on our indebtedness. Non-capitalized interest expense was nominal in 2011.

Foreign exchange (losses) gains

Net foreign currency transaction gains were $1.9 million and $0.7 million during the three and nine months ended September 30, 2012, respectively. This compares to foreign currency transaction losses of $2.0 million and $1.8 million during the three and nine months ended September 30, 2011, respectively. These gains and losses relate primarily to the revaluation in Euro of U.S. dollar monetary balances owed by Molycorp Silmet.

47

Other Expense

Other expense increased by approximately $37.5 million in the nine months ended September 30, 2012 from the corresponding period in 2011, primarily as a result of a loss recognized upon settlement of the contingent forward contract we entered into to purchase Canadian dollars with a notional amount of Cdn $870.0 million to manage the foreign currency exposure with respect to our acquisition of Molycorp Canada.

Capital Expenditures

Our consolidated capital expenditures, on an accrual basis and excluding capitalized interest, totaled $195.9 million and $692.8 million for the three and nine months ended September 30, 2012, as compared to $105.4 million and $219.0 million for the three and nine months ended September 30, 2011, respectively. The majority of these capitalized costs relate to Project Phoenix Phase 1 and Project Phoenix Phase 2 at our Molycorp Mountain Pass facility.

Related Party Transactions

We had no payments in 2012 and made principal payments of $0.6 million and $2.3 million for the three and nine month period ended September 30, 2011, respectively, under the inventory financing arrangement with Traxys North America LLC, which we refer to collectively with its affiliates, as Traxys and affiliates, a subsidiary of one of our stockholders, Traxys S.a.r.l.

We and Traxys and affiliates jointly market and sell certain lanthanum oxide, cerium oxide, misch metal and erbium oxide products. Pursuant to the terms of this other arrangement, we and Traxys and affiliates split gross margin equally once all costs associated with the sale are recovered by both parties. In addition, we purchased $6.2 million of lanthanum oxide from Traxys and affiliates during the nine months ended September 30, 2011. We did not have any material purchases from Traxys and affiliates in 2012.

During the period from January 1, 2012 to June 11, 2012, we sold neodymium/ praseodymium oxides for $4.3 million and heavy rare earths for $1.6 million to Neo Material Technologies, Inc.

For the quarter ended September 30, 2012 and for the period from June 12, 2012 to September 30, 2012, we purchased $1.4 million and $1.9 million, respectively, of compounds from Toda Magnequench Magnetic Materials Co. Ltd., or TMT (an equity method investee acquired as part of Molycorp Canada), and we sold $1.3 million and $1.4 million of Neo Powders to TMT, respectively.

During the same periods, we purchased metals and received services from Ganzhou Keli Rare Earth New Material Co., Ltd., or Keli (an equity method investee acquired as part of Molycorp Canada), amounting to $16.1 million and $21.4 million, respectively.

For the quarter ended September 30, 2012 and for the period from June 12, 2012 to September 30, 2012, we purchased $1.3 million and $1.7 million of gallium metal, respectively, from Ingal Stade (an equity method investee acquired as part of Molycorp Canada).

Outlook for the Remainder of 2012

We anticipate China-based producers and suppliers will continue to limit the quantity of REO available outside of China for the remainder of 2012. On several occasions, the Chinese government has called for greater use of rare earths for China's own domestic manufacturing as it aims to boost the use of rare earths in high-end manufacturing. Recently, the Chinese government announced a significant reduction of mining permits in an effort to further consolidate the rare earth industry to achieve efficiencies in the industry and curb illegal exports of REE from China. Independent industry sources have also indicated that China is importing rare earth materials while investing in downstream operations, thus increasing the likelihood that China will make greater use of Western rare earth material in addition to its own. We will continue to progressively expand our products and markets through the remainder of 2012, including market penetrations of our SorbX^TM (formerly XSORBX) technology into the water treatment industry. Additionally, we will continue to supply Molycorp Silmet and MMA with rare earth feedstocks, and our Molycorp Mountain Pass facility will increase shipments of certain REO to our facilities in Asia for use in value-added and downstream rare earth applications. However, the volume of rare earth products we are able to produce at our Mountain Pass facility will remain limited by the capability of our existing production facilities while ramping up to Project Phoenix Phase 1 production capacity. We expect our REO production in 2012 to be between 8,000 mt and 10,000 mt

48

across our facilities at Mountain Pass, Molycorp Silmet and MMA. We believe that our consolidated sales in 2012 will be sufficient to fund our normal operating activities throughout the year, including consolidated selling, general and administrative expenses. Based on our ongoing monitoring of the rare earth industry and our business, we expect that our cash flow from operations for the remainder of 2012 will likely be less than we originally expected.

Capital Investments

We are incurring significant capital expenditures under our plans to modernize and expand our Molycorp Mountain Pass facility, as well as consistent expenditures to replace assets necessary to sustain safe and reliable production. Most of the facilities and equipment acquired in connection with the acquisition of the Molycorp Mountain Pass facility are at least 20 years

old. We are executing an accelerated modernization plan that includes the refurbishment of the Molycorp Mountain Pass mine and related processing facilities through 2012 in order to increase our REO production. We implemented a plan to accelerate Project Phoenix Phase 1 start-up to take advantage of favorable project economics at a time when the REO markets were robust. This acceleration, if successful, will help to improve the diversity of global supply, which continues to be an urgent matter for rare earth consumers. By accelerating Project Phoenix Phase 1 start-up, we also expect to reduce the overall project risk by allowing for a more orderly and sequential startup of the various circuits and facilities of this complex project.

Cash expenditures for Project Phoenix Phase 1, Project Phoenix Phase 2 and other remaining 2012 capital projects related to operations at the Molycorp Mountain Pass facility are expected to total approximately $170.0 million for the fourth quarter of 2012, and approximately $305.0 million in the first half of 2013, respectively.

These estimated cash expenditures described above represent the estimated remaining expenditures for Project Phoenix Phase 1, Project Phoenix Phase 2 and our other remaining 2012 capital projects related to operations at the Molycorp Mountain Pass facility. Including the applicable remaining expenditures, the aggregate cost of Project Phoenix Phase 1 and Project Phoenix Phase 2 is estimated to be approximately $1.25 billion for engineering, procurement and construction, or EPC, preliminary engineering, insurance, permitting, legal, start-up, commissioning and other costs. All amounts for future capital spending are estimates that include certain discretionary amounts and are subject to change as the projects are further developed. These estimates do not include capitalized interest.

The estimated total costs for Project Phoenix Phase 1 and Project Phoenix Phase 2 include estimated additional EPC expenditures totaling up to $150.0 million for corrections resulting from certain defective engineering work, other engineering, design and scope changes and other cost increases. We are pursuing actions to recoup certain costs arising from defective engineering work, including making claims against applicable insurance policies, although there can be no assurance that we will be able to recoup all or any portion of such costs. We regularly monitor our capital projects to identify opportunities to reduce their total costs.    

We expect to incur capital expenditures of approximately $10.0 million during the fourth quarter of 2012 at all our other operating facilities.

Liquidity and Capital Resources

We expect to fund the remaining capital expenditures under Project Phoenix Phase 1, Project Phoenix Phase 2 and other capital expenditures related to operations at Molycorp Mountain Pass and all other operating facilities, as well as working capital and other cash requirements, with our available cash balances of $436.0 million at September 30, 2012, anticipated future cash flow from operations and potential proceeds from revolving credit facilities or certain equipment financing that we are currently pursuing in our normal process of properly managing our cash and working capital requirements.

There can be no assurance that we will be successful in securing access to additional cash proceeds through the revolving credit facilities and lease or loan financing for certain equipment that we are currently pursuing, or other forms of financing on commercially acceptable terms, or at all. Accordingly, if necessary, we believe we have the ability to curtail capital expenditures and revise our current business plan to the extent necessary to preserve adequate liquidity sufficient to sustain operations.

Other cash requirements are expected to include an additional contribution of approximately $3.8 million to IMJ in September 2013. The actual remittance amounts to IMJ will vary depending on the future exchange rate between the U.S. dollar and the Japanese Yen and the achievement of certain milestones by the joint venture. We also anticipate making cash investments in other current and new ventures consistent with our mine-to-magnets strategy totaling approximately $8.0 million in the fourth quarter of 2012 and approximately $20.0 million in 2013.

Cash Used in Operating Activities

Net cash used in operating activities was $47.2 million during the nine months ended September 30, 2012, as compared to a positive cash flow from operations of $28.7 million for the same period in 2011. This change was primarily driven by lower sales prices combined with a significant increase in operating expenses, including corporate development costs associated with the Molycorp Canada acquisition and the loss of $37.5 million recognized upon settlement of the contingent forward contract described above.

Net cash used in investing activities increased to $1.3 billion during the nine months ended September 30, 2012 as compared to $198.0 million for the same period in 2011. This increase was due primarily to our acquisition of Molycorp Canada, higher capital expenditures as part our modernization and expansion plan at Molycorp Mountain Pass and our contributions to IMJ.

Financing Activities

Net cash provided from financing activities increased from $415.1 million during the nine months ended September 30, 2011 to $1.3 billion during the same period in 2012, due to the issuance of $650.0 million aggregate principal amount of our Senior Notes, Molymet's $390.2 million investment in our common stock, the issuance of $414.0 million aggregate principal amount of our 6.00% Convertible Notes, the issuance of 13,800,000 Primary Shares, and bank advances of $9.5 million. These cash inflows were partially offset by the repayment of $227.5 million aggregate principal amount of the Debentures acquired as part of the Molycorp Canada acquisition, including interest, the $8.5 million preferred stock dividend that we paid through September 1, 2012, and $0.9 million of other short-term debt repayments.

Liquidity of Subsidiaries

Our total $436.0 million of cash and cash equivalents at September 30, 2012 is comprised of: 1) $175.4 million held by Molycorp Minerals, LLC; 2) $0.7 million held by Molycorp Silmet; 3) $3.8 million held by MMA; 4) $256.0 million held by Molycorp Canada; and 5) $0.1 million held by our sales office in Tokyo, Japan.

At September 30, 2012, our foreign operating subsidiaries held cash and cash equivalents in foreign countries as follows (in thousands):

China (including Hong Kong)	$	144,398
Barbados	22,315
Canada	25,426
Japan	12,338
Germany	5,504
United Kingdom	2,070
Thailand	1,197
Korea	451
Singapore	563
Estonia	725
Total cash and cash equivalents in foreign countries	214,987
United States	221,038
Total cash and cash equivalents	$	436,025

Approximately 17% of the total cash and cash equivalents held by our foreign operating subsidiaries relate to undistributed earnings that are considered indefinitely reinvested in these foreign subsidiaries. If such earnings were repatriated, additional tax expense may result, although the calculation of such additional taxes is not practicable.

In addition to cash and cash equivalents, the primary sources of liquidity of our operating subsidiaries are cash provided by operations and, in the case of our operations in China, Japan and Estonia, borrowing under certain bank loans. From time to time, the sources of liquidity for our operating subsidiaries may be supplemented by short-term loans from Molycorp Minerals, LLC. At September 30, 2012, Molycorp Minerals, LLC advanced funds, in the form of interest bearing

50

unsecured promissory notes, to Molycorp Silmet for $17.2 million, and to MMA for $3.0 million, including accrued interest. Our operating subsidiaries' liquidity generally is used to fund their working capital requirements, capital expenditures and third-party debt service requirements.

Contractual Obligations

At September 30, 2012, we had the following contractual obligations, in thousands:

	Payments Due by Period
Contractual Obligations	Total		Less Than 1 Year		1 - 3 Years		4 - 5 Years		More Than 5 Years

(2) Represents contractual commitments for the purchase of materials and services from vendors. Amount includes $2.4 million of potential environmental obligations related to defects in pond liners, and $8.0 million in acquisition related commitments.

(3) Represents primarily payments due to employees for awards under our annual incentive plan.

(4) Under applicable environmental laws and regulations, we are subject to reclamation and remediation obligations resulting from our operations. The amounts presented above represent our estimated future undiscounted cash flows required to satisfy the obligations currently known to us.

Off-Balance Sheet Arrangements

As of September 30, 2012, our only off-balance sheet arrangements are the operating leases and purchase obligations included in the contractual obligations table above.

Recent Accounting Pronouncements

In December 2011, the Financial Accounting Standard Board, or FASB, issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05. ASU 2011-12 defers the requirement that companies present reclassification adjustments for each component of Accumulated Other Comprehensive Income, or AOCI, in both net income and other comprehensive income on the face of the financial statements. Companies will continue to be required to present amounts reclassified out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements. During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income. For the three and nine month periods ended September 30, 2012, we did not have any reclassification adjustments for components of AOCI.

In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment. Under this updated guidance, an entity will have the option to first assess qualitatively whether it is necessary to perform the current two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is necessary. The update does not change how an entity performs the two-step impairment test under the current guidance. This ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. We do not expect the adoption of this updated guidance to have a significant impact on our

51

financial statements.

GLOSSARY OF SELECTED REEs, RARE METALS AND MINING TERMS

The following is a glossary of selected REEs, rare metals and mining terms used in this quarterly report on Form 10-Q that may be technical in nature:

Assay	The analysis of the proportions of metals in ore, or the testing of an ore or mineral for composition, purity, weight, or other properties of commercial interest.
Bastnasite	Bastnasite is a mixed-lanthanide fluoro-carbonate mineral (Ln F CO3) that currently provides the bulk of the world's supply of the light REEs. Bastnasite and monazite are the two most common sources of cerium and other REEs. Bastnasite is found in carbonatites, igneous carbonate rocks that melt at unusually low temperatures.
Bonded magnet	Bonded neodymium-magnets are prepared by melt spinning a thin ribbon of the Nd-Fe-B alloy. The ribbon contains randomly oriented Nd2Fe14B nano-scale grains. This ribbon is then pulverized into particles, mixed with a polymer and either compression or injection molded into bonded magnets. Bonded magnets offer less flux than sintered magnets, but can be net-shape formed into intricately shaped parts and do not suffer significant eddy current losses.
Cerium	Cerium (Ce) is a soft, silvery, ductile metal which easily oxidizes in air. Cerium is the most abundant of the REEs, and is found in a number of minerals, including monazite and bastnasite. Cerium has two relatively stable oxidation states, enabling both the storage of oxygen and its widespread use in catalytic converters. Cerium is also widely used in glass polish.
Concentrate	A mineral processing product that generally describes the material that is produced after crushing and grinding ore, effecting significant separation of gangue (waste) minerals from the desired metal and/or metal minerals, and discarding the waste minerals. The resulting “concentrate” of minerals typically has an order of magnitude higher content of minerals than the beginning ore material.
Cut-off grade	The lowest grade of mineralized material that qualifies as ore in a given deposit. The grade above which minerals are considered economically mineable considering the following parameters: estimates over the relevant period of mining costs, ore treatment costs, general and administrative costs, refining costs, royalty expenses, by-product credits, process and refining recovery rates and price.
Didymium	Didymium is a natural and unseparated combination of neodymium and praseodymium, which is approximately 75% neodymium and 25% praseodymium, depending on the ore.
Dysprosium	A few percent of Dysprosium (Dy) is often added to high power neodymium iron boron magnets to increase their resistance to demagnetization. A minor use of dysprosium is in the magnetostrictive alloy, based on DyTbFe called terfenol-D.
Europium	Europium (Eu) is desirable due to its photon emission. Excitation of the europium atom, by absorption of electrons or by UV radiation, results in changes in energy levels that create a visible emission. Almost all practical uses of europium utilize this luminescent behavior.
Gadolinium	Gadolinium (Gd) absorbs neutrons and therefore is used for shielding and controlling neutron radiography and in nuclear reactors. Because of its paramagnetic properties, solutions of organic gadolinium complexes and gadolinium compounds are popular intravenous contrast enhancing agents for medical Magnetic Resonance Imaging contrast agents in (MRI). Gadolinium is sometimes added to samarium cobalt magnets to make their magnetic properties less temperature dependent.
Gallium	Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium metal has a brilliant silvery color and its solid metal fractures conchoidally like glass. Almost all gallium is used for microelectronics.
Grade	The average REE content, as determined by assay of a metric ton of ore.
Indium	A rare, very soft, malleable and easily fusible post-transition metal that is chemically similar to gallium and thallium, and shows intermediate properties between these two. Indium's current primary application is to form transparent electrodes from indium tin oxide (ITO) in liquid crystal displays and touchscreens, and this use largely determines its global mining production. It is widely used in thin-films to form lubricated layers. It is also used for making particularly low melting point alloys, and is a component in some lead-free solders.
Lanthanum	Lanthanum (La) is the first member of the Lanthanide series. Lanthanum is a strategically important rare earth element due to its use in fluid bed cracking catalysts, FCCs, which are used in the production of transportation and aircraft fuel. Lanthanum is also used in fuel cells and batteries.
Mill	A processing plant that produces a concentrate of the valuable minerals contained in an ore.

52

Mineralization	The process or processes by which a mineral or minerals are introduced into a rock, resulting in a valuable or potentially valuable deposit.
Monazite	Monazite is a reddish-brown phosphate mineral. Monazite minerals are typically accompanied by concentrations of uranium and thorium. This has historically limited the processing of monazite, however this mineral is becoming more attractive because it typically has elevated concentrations of mid-to heavy rare earths.
Niobium	Niobium is a rare, soft, grey, ductile transition metal found in the minerals pyrochlore, the main commercial source for niobium, and columbite. Niobium is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. Although alloys contain only a maximum of 0.1%, that small percentage of niobium improves the strength of the steel. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials.
Neodymium	Neodymium (Nd) has two major uses. It is key constituent of NdFeB permanent magnets and it is an additive to capacitor dielectrics. NdFeB magnets maximize the power/weight ratio, and are found in a large variety of motors, generators, sensors and hard disk drives. Capacitors containing neodymium are found in cellular telephones, computers and nearly all other electronic devices. A minor application of neodymium is in lasers.
Ore	That part of a mineral deposit which could be economically and legally extracted or produced at the time of reserve determination.
Overburden	In surface mining, overburden is the material that overlays an ore deposit. Overburden is removed prior to mining.
Praseodymium	Praseodymium (Pr) comprises about 4% of the lanthanide content of bastnasite and has a few specific applications, based mainly on its optical properties. It is a common coloring pigment, and is used in photographic filters, airport signal lenses, and welder's glasses. Because it chemically and magnetically is so similar to its neighbors neodymium and lanthanum, it is typically found in small amounts in applications where neodymium and lanthanum are popular, such as NdFeB magnets and catalysts. These latter applications are actually the largest uses for praseodymium because the magnet and catalyst markets are so large. Thus praseodymium plays an important role, in extending the availability of the more popular neodymium and lanthanum.
Probable reserves	Reserves for which quantity and grade and/or quality are computed from information similar to that used for proven reserves, but the sites for inspection, sampling, and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.
Proven reserves	Reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling; and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well established.
Recovery	The percentage of contained metal actually extracted from ore in the course of processing such ore.
Reserves	That part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination. Same definition as 'ore'
Rhenium	It is a silvery-white, heavy, third-row transition metal. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. The free element has the third-highest melting point and highest boiling point of any element. Rhenium resembles manganese chemically and is obtained as a by-product of molybdenum and copper ore's extraction and refinement. Nickel-based superalloys of rhenium are used in the combustion chambers, turbine blades, and exhaust nozzles of jet engines. These alloys contain up to 6% rhenium, making jet engine construction the largest single use for the element, with the chemical industry's catalytic uses being next-most important.
Samarium	Samarium (Sm) is predominantly used to produce samarium cobalt magnets. Although these magnets are slightly less powerful than NdFeB magnets at room temperature, samarium cobalt magnets can be used over a wider range of temperatures and are less susceptible to corrosion.
Sintered magnet	Sintered neodymium-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled to tiny particles. This undergoes a process of liquid-phase sintering whereby the powder is magnetically aligned into dense blocks which are then heat-treated, cut to shape, surface treated and magnetized.
Tantalum	Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion resistant. It is part of the refractory metals group, which are widely used as minor component in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum, but its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers.

53

Terbium	Terbium (Tb) is used primarily as a phosphor, either in fluorescent lamps or x-ray screens. It can replace dysprosium in NdFeB magnets but usually does not because of its cost. A minor use of terbium is in the magnetostrictive alloy, based on DyTbFe called terfenol-D.
Yttrium	Yttrium (Y), although not a lanthanide series element, is often considered to be a rare earth element and its behavior is similar to heavy rare earth elements. It is predominantly utilized in lighting applications and ceramics. Other uses include resonators, lasers, microwave communication devices and other electronic devices.
Zirconium oxide	A white amorphous powder that is insoluble in water and highly refractory, used as a pigment for paints, a catalyst, and an abrasive.

54

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our operations may be impacted by commodity prices, geographic concentration, changes in interest rates and foreign currency exchange rates.

Commodity Price Risk

Our current principal product mix, including cerium, lanthanum, neodymium, praseodymium, yttrium, europium, dysprosium, terbium, zirconium oxides, gallium, indium, rhenium, tantalum and niobium are commodities but are not traded on any commodity exchange. As such, direct hedging of the prices for future production cannot be undertaken. A portion of our current business is conducted in the spot market; therefore, prices can vary with the transaction and individual bids received. Our products are primarily marketed to manufacturers as component materials. Prices will vary based on the demand for the end products being produced with the mineral resources we mine and process.

Our sales and profitability are determined principally by the price of the rare earth products, rare metals and magnet alloys that we produce and, to a lesser extent by the price of natural gas and other supplies used in the production process. The prices of our rare earth products are influenced by the price and demand of the end products that our products support, including automotive, electronics and clean energy technologies. A significant decrease in the global demand for these products may have a material adverse effect on our business. We currently have no significant hedging contracts for revenues and costs in place and intend to consider hedging strategies in the future.

Our costs and capital investments are subject to market movements in other commodities such as natural gas and chemicals. We may enter into derivative contracts for a portion of the expected usage of these products, but we do not currently have any derivative contracts on these commodities and we do not currently anticipate entering into derivative agreements on commodities.

Interest Rate Risk

Our exposure to the interest rate risk as a result of our total variable interest debt, which totaled $37.1 million at September 30, 2012, would result in an approximately $0.4 million annual increase/decrease in interest rate expense for every 100 basis point increase/decrease in the underlying interest rate. We are not significantly impacted by variations in interest rates at this time. Our exposure to interest rate risk would increase if, for example, we obtain and utilize additional debt facilities in the future.

Foreign Currency Risk

We are exposed to fluctuations of the U.S. dollar (our reporting currency) against the functional currencies of our foreign subsidiaries, including the Euro, the Canadian dollar, the Chinese Renminbi and the Japanese Yen, when we translate our foreign subsidiaries' financial statements into U.S. dollars for inclusion in our consolidated financial statements. Cumulative translation adjustments are recorded in accumulated other comprehensive income (loss) as a separate component of equity. Any increase (decrease) in the value of the U.S. dollar against those foreign currencies results in unrealized foreign currency translation losses (gains) with respect to assets acquired in, liabilities assumed from, intercompany balances with and results of operations from our foreign subsidiaries. Therefore, we may experience a negative impact on our comprehensive income (loss) and stockholders' equity with respect to our holdings in those subsidiaries as a result of foreign currency translation. We generally do not hedge against the risk that we may incur non-cash losses upon the translation of the financial statements of our foreign subsidiaries into U.S. dollars.

We are also exposed to fluctuations of the U.S. dollar against the Japanese Yen as it pertains to our investment in IMJ. We will contribute, upon achievement of certain milestones and subject to our Board of Directors' approval, Japanese Yen, or JPY 300 million (or approximately $3.8 million based on the JPY/ U.S. dollar exchange rate at September 30, 2012) in cash in exchange of ordinary shares of the joint venture over a period of twelve months, which started in January 2012. The actual remittance amounts will vary depending on the future exchange rate between the U.S. dollar and the Japanese Yen, and the achievement of certain milestones by the joint venture.

55

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of disclosure controls and procedures

In accordance with Rule 13a-15(b) of the Securities Exchange Act of 1934, or the Exchange Act, the Company's management, with the participation of the Chief Executive Officer and the Chief Financial Officer, carried out an evaluation of the effectiveness of the Company's “disclosure controls and procedures”, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, as of the end of the period covered by this report. Based on its evaluation, the Company's management, including the Chief Executive Officer and the Chief Financial Officer, have concluded that the Company's disclosure controls and procedures are effective as of September 30, 2012, so to provide reasonable assurance that material information required to be disclosed in reports the Company files or submits under the Exchange Act is made known to them timely.

We acquired Molycorp Canada in the second quarter of 2012. As such, the scope of our assessment of the effectiveness of internal control over financial reporting does not include Molycorp Canada. This exclusion is in accordance with the SEC's general guidance that an assessment of a recently acquired business may be omitted from our scope in the year of acquisition.

Changes in internal control over financial reporting

There have been no changes in the Company's internal control over financial reporting that occurred during the quarter ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

56

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

From time to time, we may become subject to various legal proceedings that are incidental to the ordinary conduct of our business.

In February 2012, a purported class action lawsuit captioned, Angelo Albano, Individually and on Behalf of All Others Similarly Situated v. Molycorp, Inc., et al., was filed against us and certain of our executive officers in the U.S. District Court for the District of Colorado. This federal court action alleges, among other things, that we and those officers violated Section 10(b) of the Securities Exchange Act of 1934 in connection with statements relating to our third quarter fiscal 2011 financial results and fourth quarter 2011 production guidance that we had filed with or furnished to the SEC, or otherwise made available to the public. In July 2012, the plaintiffs filed an amended consolidated class action complaint against us, certain of our officers and directors, certain of our private equity investors, and certain underwriters involved in our public offerings in 2011. The amended complaint alleges, among other things, that some or all of the defendants violated Sections 10(b), 20(a) and 20A of the Securities Exchange Act of 1934 as well as Sections 11, 12(a)(2) and 15 of the Securities Act of 1933. The plaintiffs are seeking unspecified damages and other relief. In October 2012, the defendants filed a motion to dismiss all the claims in the amended complaint. We believe the allegations are without merit and that we have valid defenses to such allegations. We intend to defend this action vigorously. We are unable to provide meaningful quantification of how the final resolution of these claims may impact our future consolidated financial position or results of operations.

Seven stockholder derivative lawsuits have been filed in three different jurisdictions purportedly on behalf of Molycorp, Inc., against certain of our directors and officers and certain of our private equity investors. These cases have been filed in the Delaware Court of Chancery, the U.S. District Court in Colorado, and the District Court in Arapahoe County, Colorado. They are captioned: Gaines v. Smith et al., Case No. 7282 (Del. Ch. Feb. 12, 2012); Paskowitz v. Smith et al., Case No. 7319 (Del. Ch. Mar. 9, 2012); Wilson v. Smith et al., No. 7395-VCN (Del. Ch. April 4, 2012); Wells v. Smith et al., No. 1:12-cv-00447-WJM (D. Colo. Feb. 21, 2012); Swaggerty v. Smith et al., No. 12-cv-00589-CMA-KLM (D. Colo. Mar. 7, 2012); Clem v. Smith et al., No. 12 CV 392 (Arapahoe Cnty., Colo. Feb. 24, 2012); and Nationwide Consulting, Inc. v. Smith et al., No. 12 CV 448 (Arapahoe Cnty., Colo. Mar. 5, 2012). The Clem and Nationwide cases, which were previously consolidated under the caption Clem v. Smith et al., No. 12 CV 392 (Arapahoe Cnty., Colo.), have been voluntarily dismissed without prejudice. The Wells and Swaggerty cases have both been dismissed without prejudice in favor of the lawsuits proceeding in the Delaware Court of Chancery. As a result, plaintiffs in the Wells and Swaggerty cases filed notices of appeal before the 10th Circuit. The 10th Circuit case has been fully briefed by the parties.

The derivative cases have been consolidated and are proceeding in the Delaware Court of Chancery. In August 2012, a consolidated amended shareholder derivative complaint was filed with the Delaware Court of Chancery challenging, among other things, certain sales of stock by officers, directors and private equity firms, and certain Molycorp corporate acquisitions during 2011. The amended complaint asserts causes of action for: (1) alleged breaches of fiduciary duty, including the duties of loyalty and due care; (2) alleged breach of fiduciary duty not to trade on or misuse material non-public information; (3) alleged unjust enrichment; and (4) alleged aiding and abetting a breach of fiduciary duty against controlling stockholders. On behalf of Molycorp, the plaintiffs in the derivative actions seek, among other things, monetary damages, restitution, an accounting, and certain changes to corporate governance procedures.

On October 22, 2012, the defendants filed motions to dismiss and motions to stay the derivative case with the Delaware Court of Chancery. Defendants filed their opening briefs in support of the Motions to Stay on November 5, 2012. The parties agreed that all briefing on defendants' Motions to Dismiss should be stayed pending resolution of defendants' Motions to Stay.

In August 2012, the staff of the SEC notified us that a formal order of investigation had been issued regarding, among other things, the accuracy of our public disclosures. We are cooperating with the staff of the SEC in connection with the investigation. We cannot predict the length, scope or results of the investigation or the impact, if any, of the investigation on our results of operations.

ITEM 1A. RISK FACTORS.

There were no material changes to the risk factors disclosed in Item 1A of Part I in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, as filed with the SEC on February 28, 2012.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In December 2011, the Financial Accounting Standard Board ("FASB") issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05. ASU 2011-12 defers the requirement that companies present reclassification adjustments for each component of Accumulated Other Comprehensive Income (“AOCI”) in both net income and other comprehensive income on the face of the financial statements. Companies will continue to be required to present amounts reclassified out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements. During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income. For the period ended September 30, 2012, the Company did not have any reclassification adjustments for components of AOCI.

In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment. Under this updated guidance, an entity will have the option to first assess qualitatively whether it is necessary to perform the current two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is necessary. The update does not change how an entity performs the two-step impairment test under the current guidance. This ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The Company does not expect the adoption of this updated guidance to have a significant impact on its financial statements.

Operating lease obligations	$	9,826	$	1,417	$	5,929	$	1,110	$	1,370

(b) Purchase Commitments

In connection with the Molycorp Mountain Pass facility modernization and expansion and future operations, the Company entered into contractual commitments for the purchase of materials and services from various vendors. As a result of the Molycorp Canada acquisition, the Company assumed other purchase obligations totaling $6.3 million at September 30, 2012, which are expected to be settled between 2012 and 2014. Future payments for all purchase commitments at September 30, 2012 were as follows:

(In thousands)	Total		Less Than 1 Year		1 - 3 Years		4 - 5 Years		More Than 5 Years
Purchase obligations and other commitment	$	287,819	$	284,534	$	1,798	$	538	$	949

(c) Potential Environmental Obligations

As part of its ongoing remediation efforts at the Molycorp Mountain Pass facility, the Company identified liner defects in three of the onsite evaporation ponds in 2011. These defects led to minor groundwater contamination issues that are limited to a small area directly underneath the evaporation ponds. In order to remediate this issue, the Company will replace the primary lining system and might have to install a groundwater recovery system. The Company estimated the cost of these items at between $2.4 million and $4.6 million, which will be treated as capital expenditures and are included in the purchase obligations table above. The Company is in the process of finalizing the remediation plans with the Regional Water Quality Control Board.

(d) Labor Contract

Certain Molycorp Mountain Pass facility employees are covered by a collective bargaining agreement with the United Steelworkers of America that expires on March 15, 2015. At September 30, 2012, 226 employees, or approximately 60% of the Company’s workforce at the Molycorp Mountain Pass facility, were covered by this collective bargaining agreement.

At September 30, 2012, 172 employees, or approximately 29% of the workforce at the Company’s Molycorp Silmet facility, were unionized employees. The contract with the labor union in Estonia was renewed in February 2012.

(e) Reclamation Surety Bonds

At September 30, 2012, Molycorp had placed $28.8 million of surety bonds with California state and regional agencies to secure its Mountain Pass facility closure and reclamation obligations.

(f) Purported Class Action, Derivative Lawsuits and Investigation

In February 2012, a purported class action lawsuit captioned, Angelo Albano, Individually and on Behalf of All Others Similarly Situated v. Molycorp, Inc., et al., was filed against the Company and certain of its executive officers in the U.S. District Court for the District of Colorado. This federal court action alleges, among other things, that the Company and those officers violated Section 10(b) of the Securities Exchange Act of 1934 in connection with statements relating to its third quarter fiscal 2011 financial results and fourth quarter 2011 production guidance that the Company had filed with or furnished to the SEC, or otherwise made available to the public. In July 2012, the plaintiffs filed an amended consolidated class action complaint against the Company, certain of its officers and directors, certain of its private equity investors, and certain underwriters involved in our public offerings in 2011. The amended complaint alleges, among other things, that some or all of the defendants violated Sections 10(b), 20(a) and 20A of the Securities Exchange Act of 1934 as well as Sections 11, 12(a)(2) and 15 of the Securities Act of 1933. The plaintiffs are seeking unspecified damages and other relief. In October 2012, the defendants filed a motion to dismiss all the claims in the amended complaint. The Company believes the allegations are without merit and that it has valid defenses to such allegations. The Company intends to defend this action vigorously. The Company is unable to provide meaningful quantification of how the final resolution of these claims may impact its future consolidated financial position or results of operations.

Seven stockholder derivative lawsuits have been filed in three different jurisdictions purportedly on behalf of Molycorp, Inc., against certain of its directors and officers, and certain of its private equity investors. These cases have been filed in the Delaware Court of Chancery, the U.S. District Court in Colorado, and the District Court in Arapahoe County, Colorado. They are captioned: Gaines v. Smith et al., Case No. 7282 (Del. Ch. Feb. 12, 2012); Paskowitz v. Smith et al., Case No. 7319 (Del. Ch. Mar. 9, 2012); Wilson v. Smith et al., No. 7395-VCN (Del. Ch. April 4, 2012); Wells v. Smith et al., No. 1:12-cv-00447-WJM (D. Colo. Feb. 21, 2012); Swaggerty v. Smith et al., No. 12-cv-00589-CMA-KLM (D. Colo. Mar. 7, 2012); Clem v. Smith et al., No. 12 CV 392 (Arapahoe Cnty., Colo. Feb. 24, 2012); and Nationwide Consulting, Inc. v. Smith et al., No. 12 CV 448 (Arapahoe Cnty., Colo. Mar. 5, 2012). The Clem and Nationwide cases, which were previously consolidated under the caption Clem v. Smith et al., No. 12 CV 392 (Arapahoe Cnty., Colo.), have been voluntarily dismissed without prejudice. The Wells and Swaggerty cases have both been dismissed without prejudice in favor of the lawsuits proceeding in the Delaware Court of Chancery. As a result, plaintiffs in the Wells and Swaggerty cases filed notices of appeal before the 10th Circuit. The defendants have filed a responsive brief in the 10th Circuit in the Wells and Swaggerty cases. The 10th Circuit case has been fully briefed by the parties.

The derivative cases have been consolidated and are proceeding in the Delaware Court of Chancery. In August 2012, a consolidated amended shareholder derivative complaint was filed with the Delaware Court of Chancery challenging, among other things, certain sales of stock by officers, directors and private equity firms, and certain Molycorp corporate acquisitions during 2011. The amended complaint asserts causes of action for: (1) alleged breaches of fiduciary duty, including the duties of loyalty and due care; (2) alleged breach of fiduciary duty not to trade on or misuse material non-public information; (3) alleged unjust enrichment; and (4) alleged aiding and abetting a breach of fiduciary duty against controlling stockholders. On behalf of Molycorp, the plaintiffs in the derivative actions seek, among other things, monetary damages, restitution, an accounting, and certain changes to corporate governance procedures.

On October 22, 2012, the defendants filed motions to dismiss and motions to stay the derivative case with the Delaware Court of Chancery. Defendants filed their opening briefs in support of the Motions to Stay on November 5, 2012. The parties agreed that all briefing on defendants' Motions to Dismiss should be stayed pending resolution of defendants' Motions to Stay.

In August 2012, the staff of the SEC notified the Company that a formal order of investigation had been issued regarding, among other things, the accuracy of the Company's public disclosures. The Company is cooperating with the staff of the SEC in connection with the investigation. The Company cannot predict the length, scope or results of the investigation or the impact, if any, of the investigation on the Company's results of operations.

Segment Reporting [Abstract]

Segment Information

Segment Information

In the third quarter of 2012, management reorganized the Company's operations into four new reportable segments to better reflect its primary activities as a global rare earth and magnetics enterprise: Resources; Chemicals and Oxides; Magnetic Materials and Alloys; and Rare Metals. The new composition of the Company's reportable segments is based on a combination of product lines and technologies aligned with its mine-to-magnet strategy.

The Resources segment includes: the Company's operations at its Molycorp Mountain Pass facility where it conducts rare earth minerals extraction to produce rare earth concentrates; REO, including lanthanum, cerium, didymium, neodymium, praseodymium and yttrium; heavy rare earth elements, such as samarium, europium, gadolinium, terbium, dysprosium, and others; didymium rare earth metal; and SorbX^TM (formerly XSORBX), a line of proprietary rare earth-based water treatment products.

The Chemicals and Oxides segment includes: production of REO at the Company's operations in Sillamäe, Estonia; heavy rare earths from the Company's facilities in Jiangyin, Jiangsu Province, China; and production of REO, salts of rare earth elements ("REEs"), zirconium-based engineered materials and mixed rare earth/zirconium oxides from the Company's facilities in Zibo, Shandong Province, China. Rare earths products and zirconium-based engineered products are primarily supplied to the automotive catalyst, electronics, ceramic, clean technology and glass industries.

The Magnetic Materials and Alloys segment includes: the production of Neo Powders through Molycorp's wholly-owned manufacturing facilities in Tianjin, China and Korat, Thailand, under the Molycorp Magnequench brand. Neo Powders are used to make bonded magnets for a variety of electronic and mechanical products such as micro motors, precision motors, sensors and other applications requiring high levels of magnetic strength, flexibility, small size and reduced weight. This operating segment also includes manufacturing of neodymium and samarium magnet alloys, other specialty alloy products and rare earth metals at the Company's facility in Tolleson, Arizona.

The Rare Metals segment comprises: Molycorp's production of gallium, indium, tantalum and rhenium from its operations in Quapaw, Oklahoma; Blanding, Utah; Peterborough, Ontario; Napanee, Ontario; Sagard, Germany; and Hyeongok Industrial Zone in South Korea. This operating segment also includes tantalum and niobium from the Company's operations in Sillamäe, Estonia. Rare metals are primarily used in the wireless, light-emitting diode, flat panel display, turbine, solar and catalyst industries.

The asset retirement obligation is recognized only within the Resources segment, and certain government grants are applicable only to the Estonian operations within the Chemicals and Oxides and Rare Metals segment. In addition, the annual profit earned from the Estonian operations are not taxed. In accordance with the Estonian Income Tax Act, only distribution of annual profit is subject to income tax in Estonia. Intersegment sales and transfers are based on similar arms-length transactions with third parties at the time of the sale.

    As noted below, some of the information for the nine months ended September 30, 2012 is actually for the period from June 12, 2012 (following the acquisition of Molycorp Canada) through September 30, 2012.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative Instruments

The Company accounts for derivative instruments using the fair value method. GAAP provides for a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.

As a result of the Molycorp Canada acquisition, the Company assumed a liability associated with the put option issued to holders of the noncontrolling interest of Buss & Buss, a business acquired by Molycorp Canada's predecessor company. The Buss & Buss put option is related to a share purchase agreement (“SPA”) between NMT Holding GmbH, a German subsidiary of the Company, and the shareholders of Buss & Buss entered into May 27, 2010 by Molycorp Canada's predecessor company. The SPA includes a call and a put option on shares of the remaining shareholder and his legal successors. If the call option is exercised by the Company, a premium is added to the consideration to purchase the underlying shares in Buss & Buss. If the put option is exercised by the remaining shareholder of Buss & Buss or his legal successors, a discount will reduce the cost basis of the securities sold to the Company. The Company does not account for this derivative as a hedge. The put option had a fair value of $8.8 million at September 30, 2012, recorded as Derivative liability in the condensed consolidated balance sheets. The change in fair value of the put option resulted in an unrealized loss of $0.4 million for the period from June 12, 2012 to September 30, 2012, which was recognized in Interest expense in the condensed consolidated statements of operations and comprehensive income.

The technique Molycorp used to fair value this derivative is the income approach based on a discounted cash flow model. With the exception of the risk free interest rate, the inputs used to fair value this put option are based on unobservable Level 3 inputs based on management's assumptions. These inputs include: equity-risk premium, risk premium, size premium and growth rate. Any reasonably foreseeable changes in assumed levels of unobservable inputs used to fair value this put option would not be expected to have a material impact on the Company's financial position or results of operations.

On March 28, 2012, the Company entered into a contingent forward contract to purchase Canadian dollars with a notional amount of Cdn$870.0 million to manage the foreign currency exposure with respect to its planned acquisition of Molycorp Canada. The Company did not apply hedge accounting to this contingent forward contract. Upon settlement of this derivative on June 11, 2012 (Molycorp Canada acquisition date), the Company recognized a loss of $37.5 million in Other expense. Of this loss, $6.7 million was recognized during the three months ended March 31, 2012 and the remainder during the second quarter of 2012.

Capital Requirements

Cash expenditures for the Molycorp Mountain Pass facility plant modernization and expansion efforts, including achieving an annual production capacity of 19,050 mt (“Project Phoenix Phase 1”), the second phase capacity expansion plan to 40,000 mt (“Project Phoenix Phase 2”) and other remaining 2012 capital projects related to operations at the Molycorp Mountain Pass facility are expected to total approximately $170.0 million for the fourth quarter of 2012, and approximately $305.0 million in the first half of 2013, respectively.

These estimated cash expenditures described above represent the estimated remaining expenditures for Project Phoenix Phase 1, Project Phoenix Phase 2 and the Company's other remaining 2012 capital projects related to operations at the Molycorp Mountain Pass facility. Including the applicable remaining expenditures, the aggregate cost of Project Phoenix Phase 1 and Project Phoenix Phase 2 is estimated to be approximately $1.25 billion for engineering, procurement and construction (“EPC”), preliminary engineering, insurance, permitting, legal, start-up, commissioning and other costs. All amounts for future capital spending are estimates that include certain discretionary amounts and are subject to change as the projects are further developed. These estimates do not include capitalized interest.

The estimated total costs for Project Phoenix Phase 1 and Project Phoenix Phase 2 include estimated additional EPC expenditures totaling up to $150.0 million for corrections resulting from certain defective engineering work, other engineering, design and scope changes and other cost increases. The Company is pursuing actions to recoup certain costs arising from defective engineering work, including making claims against applicable insurance policies, although there can be no assurance that the Company will be able to recoup all or any portion of such costs. The Company regularly monitors its capital projects to identify opportunities to reduce their total costs.

Anticipated capital expenditures at all other operating facilities of the Company are expected to be approximately $10.0 million during the fourth quarter of 2012. See Note 7.

Other cash requirements include planned contributions to Intermetallics Japan (“IMJ”), the Company's joint venture to manufacture sintered NdFeB permanent rare earth magnets. Molycorp will invest, upon achievement of certain milestones, Japanese Yen (JPY) 2.5 billion in cash, in exchange for ordinary shares of IMJ. The actual remittance amounts will vary depending on the future exchange rate between the U.S. dollar and the Japanese Yen, and the achievement of certain milestones by the joint venture. The Company invested $27.7 million (representing JPY 2.2 billion) to IMJ through September 30, 2012, and plans to invest an additional JPY 300 million (or approximately $3.8 million based on the JPY/ U.S. dollar exchange rate at September 30, 2012) in September 2013. See Note 10. The Company also anticipates making cash investments in other current and new ventures consistent with its mine-to-magnets strategy totaling approximately $8.0 million in the fourth quarter of 2012 and approximately $20.0 million in 2013.

Molycorp expects to fund the remaining capital expenditures under Project Phoenix Phase 1, Project Phoenix Phase 2 and other capital expenditures related to operations at the Molycorp Mountain Pass facility and all other operating facilities, as well as working capital and other cash requirements, with its available cash balances of $436.0 million at September 30, 2012, anticipated future cash flow from operations, and potential proceeds from revolving credit facilities or certain equipment financing that the Company is currently pursuing in its normal process of properly managing its cash and working capital requirements.

There can be no assurance that the Company will be successful in securing access to additional cash proceeds through the revolving credit facilities and lease or loan financing for certain equipment that it is currently pursuing, or other forms of financing on commercially acceptable terms, or at all. Accordingly, if necessary, the Company believes it has the ability to curtail capital expenditures and revise its current business plan to the extent necessary to preserve adequate liquidity sufficient to sustain operations.

Stockholders' Equity Note [Abstract]

Stockholders' Equity

Stockholders’ Equity

At September 30, 2012 and December 31, 2011, the Company had 137,957,451 and 83,896,043 shares of common stock outstanding, respectively, and 2,070,000 shares of 5.50% Series A Mandatory Convertible Preferred Stock (“Convertible Preferred Stock”) outstanding.

Concurrently with the issuance of the 6.00% Convertible Notes discussed in Note 14, the Company issued a total of 13,800,000 shares of its common stock at a price to the public of $10.00 per share (the “Primary Shares”) in a separate underwritten public offering. The underwriters received a 6.00% fee in the form of an underwriter's discount for the Primary Shares plus a $1.5 million flat fee to the representative of the underwriters of the Primary Shares. Certain officers, directors and other related parties of the Company participated in offering of the Primary Shares by purchasing 7,090,000 of the total Primary Shares issued, but no underwriting fees were charged to the Company for the purchase by the insiders.

At the same time of the issuance of the 6.00% Convertible Notes and the Primary Shares, and as further discussed in Note 14, the Company entered into a share lending agreement with MSCS, pursuant to which it has agreed to loan to MSCS 13,800,000 shares of common stock. The Company received no proceeds from the Borrowed Shares, but only a nominal lending fee from MSCS for the use of these loaned shares. The Borrowed Shares are issued and outstanding for corporate law purposes. However, based on certain contractual undertakings of MSCS in the share lending agreement that have the effect of substantially eliminating the economic dilution that otherwise would result from the issuance of the Borrowed Shares, the Borrowed Shares will not be considered outstanding for the purpose of computing and reporting Molycorp's earnings per share.

As a result of the conversion of the Debentures, as further discussed in Note 14, a portion of the Debentures tendered was converted into 99,723 shares of Molycorp common stock.

In connection with of the acquisition of Molycorp Canada on June 11, 2012, Molycorp and MCP Exchangeco Inc. issued an aggregate of 13,545,426 shares of common stock and 507,203 Exchangeable Shares, the latter without par value, in consideration for that portion of the purchase price Molycorp paid to Molycorp Canada’s former shareholders who elected to receive shares of Molycorp common stock in addition to or in lieu of cash on the acquisition date. The $284.1 million fair value recorded in additional paid-in capital related to the issuance of acquisition consideration was based on the closing price of the Company’s common stock on June 11, 2012. As of September 30, 2012, 316,860 shares of the Exchangeable Shares had been converted into shares of Molycorp common stock.

On March 8, 2012, Molibdenos y Metales S.A. (“Molymet”), the world’s largest processor of molybdenum and rhenium, headquartered in Santiago, Chile, purchased 12,500,000 shares of the Company’s common stock for $390.1 million, net of stock issuance costs of $0.1 million, at a purchase price of $31.218 per share, which price was determined based on the average daily volume weighted average price of the Company’s common stock on The New York Stock Exchange for the 20 consecutive trading days immediately preceding the date of the agreement, plus a 10% premium. Pursuant to this investment, Molymet acquired the right to nominate a member of the Company’s Board of Directors for so long as Molymet owns a certain percentage of the Company’s common stock.

In February, May and August 2012, the Company declared a cash dividend of $1.375 per share on the Convertible Preferred Stock, respectively. The Company paid $2.8 million of the aggregate dividend in the third quarter of 2012, and a total of $8.5 million during the nine months ended September 30, 2012.

Stock-Based Compensation

Stock-Based Compensation

Starting in the first quarter of 2012, the Company granted performance-based restricted stock units ("PBRSUs") and restricted stock units (“RSUs”) to its executive officers, to certain other employees and to some non-employee directors of the Company under its 2010 Equity and Performance Incentive Plan. The RSUs vest on the third anniversary of the grant date. The grant-date fair value of RSUs is determined using the Company’s common stock price on the date of grant and is recognized as stock-based compensation expense on a straight-line basis over the three-year vesting period for the awards that are expected to vest. The PBRSUs vest with respect to between 0% and 150% of the PBRSUs granted to an individual on the basis of the achievement of certain management objectives measured by specified levels of total shareholder return relative to a defined index group over the performance period from January 1, 2012 through December 31, 2014, or upon the occurrence of certain change of control or termination events. The grant-date fair value of PBRSUs is determined using a lattice approach that incorporates a Monte Carlo simulation model. The compensation cost associated with the PBRSUs is recognized straight-line over the performance period for the awards that are expected to vest, even if the market conditions are never satisfied.

From January 1, 2012 through September 30, 2012, the Company issued 46,036 PBRSUs to certain employees, and a total of 235,474 RSUs to certain employees and non-employee directors of the Company.

Some of the RSUs granted to the non-employee directors relate to the grantees' election to convert a portion of their quarterly cash retainer into RSUs. These converted RSUs are fully vested because they relate to services already rendered by the non-employee directors. The same non-employee directors who elected to convert their cash retainer into RSUs, received additional RSUs as matching contributions by the Company equal to 25% of the converted units. The matching RSUs vest on the third anniversary of the grant date.

Also included in the RSUs issued during the first quarter of 2012 were grants related to the election by certain executive officers and other employees of the Company to convert a portion of their 2011 annual cash bonuses into RSUs. These RSUs are fully vested because they relate to services already rendered by the grantees. The conversion of the 2011 annual bonuses into RSUs resulted into an increase in Additional Paid-In Capital of $0.6 million in the first quarter of 2012. The same executive officers and other employees received additional RSUs as matching contribution by the Company equal to 25% of the converted RSUs. The matching RSUs vest on the third anniversary of the grant date.

The following tables summarize the activity related to stock-based awards from January 1, 2012 through September 30, 2012:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

Molycorp, Inc. (“Molycorp” or the “Company”) is one of the world's leading rare earth products and rare metals companies. Molycorp owns: a world-class rare earth mine and processing facilities at Mountain Pass, California (the "Molycorp Mountain Pass facility"); Molycorp Silmet, one of the largest rare earth oxide ("REO") and rare metal producers in Europe; and the only producer of rare earth alloys in the United States, Molycorp Metals and Alloys ("MMA"). Following the acquisition of Neo Material Technologies, Inc. (formerly referred to as “Neo” and now Molycorp Minerals Canada ULC or “Molycorp Canada”) on June 11, 2012, Molycorp is currently a leading global producer of neodymium-iron-boron (“NdFeB”) magnetic powders (“Neo Powders”), which are used to manufacture bonded NdFeB permanent rare earth magnets, and a leading global manufacturer and distributor of rare earths and zirconium-based engineered materials and applications, and other rare metals and their compounds.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and Regulation S-X promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”). While the December 31, 2011 balance sheet information was derived from the Company’s audited financial statements, for interim periods, GAAP and Regulation S-X do not require all information and related disclosures that are required in the annual financial statements, and all disclosures required by GAAP for annual financial statements have not been included. Therefore, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with Molycorp’s consolidated financial statements and related notes for the year ended December 31, 2011, included in Molycorp's Current Report on Form 8-K filed on August 16, 2012.

The accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, and which, in the opinion of management, are necessary for the fair presentation of Molycorp’s financial position, results of operations and cash flows at September 30, 2012, and for all periods presented. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The preparation of the financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on the Company’s historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ significantly from these estimates under different assumptions and conditions. Significant estimates made by management in the accompanying financial statements include the collectability of accounts receivable, the recoverability of inventory, the useful lives and recoverability of long-lived assets such as property, plant and equipment, intangible assets and investments, capital leases, uncertain tax positions, the fair values of assets acquired and liabilities assumed, including business combinations, and the adequacy of the Company’s asset retirement obligations.

As discussed in Note 15 of Molycorp’s Current Report on Form 8-K filed on August 16, 2012, the Company revised its previously reported results of operations for the third quarter of 2011 to correct an error in the elimination of intercompany sales in that interim period.

In addition, certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications did not affect results of operations.

Acquisitions

Acquisitions

On June 11, 2012, Molycorp completed the acquisition of all of the outstanding equity of Molycorp Canada's predecessor company pursuant to the terms of an arrangement agreement (the "Arrangement Agreement") for an aggregate purchase price of approximately $1,192.3 million. Pursuant to the Arrangement Agreement, Molycorp Canada's former shareholders elected to receive: (a) cash consideration equal to Canadian dollars ("Cdn") $11.30 per share of Molycorp Canada's predecessor company's common stock; or (b) share consideration of 0.4242 shares of Molycorp common stock or 0.4242 shares (the "Exchangeable Shares") issued by MCP Exchangeco Inc., Molycorp's wholly-owned Canadian subsidiary, which are exchangeable for shares of Molycorp's common stock on a one for one basis, per each share of Molycorp Canada's predecessor company's common stock; or (c) a combination of cash and shares of Molycorp common stock or Exchangeable Shares, all subject to the proration mechanics set forth in the Arrangement Agreement.

The consideration paid to Molycorp Canada's former shareholders was comprised of approximately $908.2 million in cash, exclusive of realized losses on the contingent forward contract to purchase $870.0 million Canadian dollars, accounted for as a separate transaction apart from the business combination, as further discussed in Note 25. Additionally, 13,545,426 shares of Molycorp common stock and 507,203 Exchangeable Shares were issued and collectively valued at $284.1 million based on the closing price of the Company's common stock on the acquisition date in accordance with the relevant accounting guidance. The Exchangeable Shares have no par value.

The following is a preliminary allocation of the Molycorp Canada purchase price (in thousands) and is based on management's preliminary estimates of the fair value of the tangible and intangible assets and liabilities of Molycorp Canada. This valuation is subject to change as the Company obtains additional information on the assets acquired and liabilities assumed during the acquisition measurement period (up to one year from the acquisition date).

	June 11, 2012
Purchase consideration:
Cash consideration	$	908,181
Fair value of Molycorp common stock and Exchangeable Shares issued	284,144
Total purchase consideration	$	1,192,325
Estimated fair values of the assets and liabilities acquired:
Cash and cash equivalents	$	317,169
Accounts receivable	101,470
Inventory	250,989
Prepaid expenses and other current assets	26,893
Property, plant and equipment	70,391
Investments	21,019
Intangibles	491,786
Goodwill	501,571
Other non-current assets	22,859
Accounts payable and accrued expenses	(138,576		)
Debt - current	(255,056		)
Other current liabilities	(29,939		)
Deferred tax liabilities	(158,177		)
Long-term debt	(281		)
Other non-current liabilities	(14,032		)
Non-controlling interests	(15,761		)
Total purchase consideration	$	1,192,325

The fair value of the accounts receivable acquired includes trade receivables of $101.5 million, which are considered to be fully collectible at September 30, 2012.

Molycorp Canada's intangible assets subject to amortization relate to: a) customer relationships of $348.1 million with a weighted average useful life of approximately fifteen years; b) rare earth quotas of $80.3 million with a useful life of approximately 11 years; c) patents of $39.8 million with a weighted average useful life of approximately two years; d) trade name of $15.8 million with a useful life of approximately ten years; and e) other of $7.8 million with a weighted average useful life of approximately twelve years.

Goodwill associated with the Molycorp Canada acquisition arose primarily because of Molycorp Canada's proven leadership in the development, processing, and distribution of technically advanced rare earth products; greater exposure to the world’s largest and fastest-growing rare earths consuming market; deferred tax liabilities and expected synergies that do not qualify for separate recognition. The goodwill is not amortized and is not deductible for tax purposes. As the purchase price allocation is not complete, the Company has not assigned the goodwill to its various reporting units.

The amounts of Molycorp Canada's sales, earnings and earnings per share included in the Company’s condensed consolidated statements of operations since the acquisition date, and the sales, earnings and earnings per share of the combined entity had the acquisition date been January 1, 2011, are as follows:

(In thousands, except per share amounts)	Sales		Net Income (Loss)			Net Income (Loss) Attributable To Molycorp			EPS Basic
Actual July 1, 2012 to September 30, 2012 (acquiree)	$	162,764	$	1,118		$	(2,322	)	$	(0.02	)
Actual June 11, 2012 to September 30, 2012 (acquiree)	$	206,397	$	1,165		$	(2,955	)	$	(0.03	)
Unaudited pro forma January 1, 2012 to September 30, 2012 (combined entity)	$	729,469	$	(74,229	)	$	(82,056	)	$	(0.77	)
Unaudited pro forma July 1, 2011 to September 30, 2011 (combined entity)	$	385,889	$	108,386		$	105,947		$	0.94
Unaudited pro forma January 1, 2011 to September 30, 2011 (combined entity)	$	860,707	$	200,951		$	192,300		$	1.69

The unaudited pro forma amounts are not necessarily indicative of the operating results that would have occurred if the Molycorp Canada acquisition had taken place on January 1, 2011.

The unaudited pro forma sales, earnings and earnings per share of the combined entity above are adjusted: a) to eliminate the effect of sales and costs that occurred previous to the business combination between the Company and Molycorp Canada; b) to reflect the net incremental depreciation and amortization expense as a result of the allocation of the purchase price to certain depreciable and amortizable assets with useful lives ranging from two to 30 years; c) the tax effect of unaudited pro forma adjustments using the Molycorp federal, state and international statutory tax rates based on the applicable tax jurisdictions; and d) the estimated net increase of interest expense associated with the issuance of the Company's 10% Senior Secured Notes (as defined below) as part of the acquisition. The unaudited pro forma earnings of the combined entity for the nine months ended September 30, 2012 were also adjusted to exclude $115.2 million of non-recurring direct transaction costs. The weighted average number of shares outstanding utilized in the EPS basic calculation have been adjusted to reflect the additional shares issued pursuant to the acquisition of Molycorp Canada and the related Molibdenos y Metales S.A. equity financing further discussed in Note 16.

For the three and nine months ended September 30, 2012, the Company recognized approximately $0.5 million and $62.0 million, respectively, of transaction costs related to the Molycorp Canada acquisition in the condensed consolidated statements of operations and comprehensive income as follows:    

(In thousands)	Three Months Ended September 30, 2012		Nine Months Ended September 30, 2012
Corporate development
Legal, accounting and advisory fees	$	465	$	16,498

Interest expense:

Molycorp Silmet and MMA

The following table summarizes the purchase prices and opening balance sheets for the acquisition of 90.023% controlling interest in Molycorp Silmet on April 1, 2011 and of MMA on April 15, 2011 (in thousands):

Effective acquisition date for financial reporting purposes:	Molycorp Silmet April 1, 2011			MMA April 15, 2011
Purchase consideration:
Cash consideration	$	9,021		$	17,500

Fair values of the assets and liabilities acquired:
Cash	$	105		$	6,395
Accounts receivable and other current assets	8,626			5,474
Inventory	37,404			11,327

Long-term debt	(3,184		)	—
Noncontrolling interest	(8,820		)	—
Total purchase consideration	$	81,674		$	17,500

The fair value of the accounts receivable acquired includes trade receivables of $5.0 million for Molycorp Silmet and $4.9 million for MMA. These trade receivables were collected by December 31, 2011. Molycorp Silmet’s intangible assets subject to amortization relate primarily to customer relationships with a weighted average useful life of 15 years. Goodwill associated with the Molycorp Silmet acquisition arose primarily because of the acquired workforce. Goodwill associated with the MMA acquisition arose primarily because of the requirement to record a deferred tax liability for the difference between the assigned values and the tax basis of assets acquired and liabilities assumed at amounts that do not reflect fair value. The goodwill is not amortized and is not deductible for tax purposes. The fair value of the noncontrolling interest in Molycorp Silmet as of April 1, 2011 was valued using a combination of the market approach and income approach.

The pro forma sales, earnings and earnings per share of the Company had both acquisitions occurred on January 1, 2011, are as follows:

(In thousands, except per share amounts)	Sales		Net Income		Net Income Attributable To Molycorp		EPS Basic
Unaudited pro forma January 1, 2011 to September 30, 2011 (combined entity)	$	297,400	$	104,170	$	103,457	$	1.17

The unaudited pro forma amounts are not necessarily indicative of the operating results that would have occurred if these acquisitions had taken place on January 1, 2011.

The 2011 earnings of the combined entity were adjusted to exclude $19.6 million of intercompany sales and $1.8 million of non-recurring acquisition-related costs the Company incurred to acquire Molycorp Silmet and MMA, and to reverse $1.1 million of purchase price variance MMA capitalized during the first quarter of 2011.

Molycorp Silmet

On April 1, 2011, Molycorp acquired 80% of the outstanding shares of Molycorp Silmet from AS Silmet Grupp in exchange for 1,593,419 shares of Molycorp common stock contractually valued at $80.0 million based on the average closing price of the Company’s common stock as reported by The New York Stock Exchange for the 20 consecutive trading days immediately preceding April 1, 2011, the acquisition date.

Generally, the acquisition-date fair value of shares of common stock transferred by the acquirer is the closing price of that stock on the same date adjusted by a discount that a market participant would require as a result of any restrictions on the sale or transferability of the stock. The fair value of common stock of $72.7 million disclosed in the table above is based on the closing price of the Company’s common stock on the acquisition date, net of an estimated discount of 23% that a market participant would require given that issuance of the shares of common stock Molycorp transferred in consideration to AS Silmet Grupp was not registered under the Securities Act of 1933 (the "Securities Act") and such shares were subject to certain lock-up provisions, which limited AS Silmet Grupp’s ability to sell these shares. AS Silmet Grupp retained a 9.977% ownership interest in Molycorp Silmet on the acquisition date; Molycorp acquired the other 10.023% from Treibacher Industrie AG for $9.0 million in cash also on April 1, 2011.

On October 24, 2011, the Company acquired the remaining 9.977% ownership interest in Molycorp Silmet for $10.0 million in cash, which resulted in an adjustment to Additional Paid-In Capital of $0.4 million for the difference between the consideration paid and the carrying value of the noncontrolling interest at October 24, 2011.

The Molycorp Silmet acquisition provided Molycorp with a European base of operations and increased the Company’s yearly REO production capacity by approximately 3,000 mt. Molycorp Silmet sources a portion of rare earth feed stocks for production of its products primarily from the Molycorp Mountain Pass facility. The main focus of Molycorp Silmet is on the production of REO and metals, including didymium metal, a critical component in the manufacture of NdFeB permanent rare earth magnets. Molycorp Silmet’s manufacturing operation is located in Sillamäe, Estonia.

MMA

On April 15, 2011, Molycorp completed the acquisition from Santoku Corporation (“Santoku”) of all the issued and outstanding shares of capital stock of Santoku America, Inc., which is now known as MMA, an Arizona-based corporation, in an all-cash transaction for $17.5 million. The acquisition provided Molycorp with access to certain intellectual properties relative to the development, processing and manufacturing of neodymium and samarium magnet alloy products. As part of the stock purchase agreement, Santoku will provide consulting services to Molycorp for the purpose of maintaining and enhancing the quality of MMA’s products. Molycorp and Santoku also entered into five-year marketing and distribution agreements for the sale and distribution of neodymium and samarium magnet alloy products produced by each party. Additionally, the parties entered into a rare earth products purchase and supply agreement through which MMA will supply Santoku with certain rare earth alloys for a two-year period at prices equal to the feedstock cost plus the applicable product premium as such terms are defined in the agreement.

Assessment of normal production levels

For the three months ended September 30, 2012 and 2011, Molycorp determined that $3.9 million and $0.8 million, respectively, of production costs would have been allocated to additional production, assuming Molycorp had been operating at normal production ranges. For the nine months ended September 30, 2012 and 2011, the Company determined that $9.8 million and $4.3 million, respectively, of production costs would have been allocated to additional production, assuming the Company had been operating at normal production ranges. As a result, these costs were excluded from inventory and instead expensed during the applicable periods. The assessment of normal production levels is judgmental and is unique to each quarter.

Write-downs of inventory

As a result of production or purchase costs in excess of net realizable value, the Company recognized write-downs of inventory of $15.0 million and $0 for the three months ended September 30, 2012 and 2011, respectively, and $41.1 million and $0.6 million for the nine months ended September 30, 2012 and 2011, respectively. In addition, the Company recognized write-downs of work-in-process and stockpile inventory totaling $0 and $0.1 million for the three months ended September 30, 2012 and 2011, respectively, and $0 and $2.3 million for the nine months ended September 30, 2012 and 2011, respectively, based on adjustments to estimated REO quantities.

Diluted earnings per share reflect the dilutive impact of potential common stock and unvested restricted shares of common stock in the weighted average number of common shares outstanding during the period, if dilutive. For this purpose, the “treasury stock method” and “if-converted method,” as applicable, are used.

Under the treasury stock method, assumed proceeds upon the exercise of stock options are considered to be used to purchase common stock at the average market price of the shares during the period. Also under the treasury stock method, fixed awards and nonvested shares, such as restricted stock units, are deemed options for purposes of computing diluted earnings per share. At September 30, 2012 and 2011, all potential common stock under the treasury stock method were antidilutive in nature; consequently, the Company did not have any adjustments between earnings per share and diluted earnings per share related to stock options and restricted stock units.

In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be antidilutive. Convertible preferred stock (such as the Convertible Preferred Stock) is antidilutive whenever the amount of the dividend declared in or accumulated for the current period per common share obtainable on conversion, including the deemed dividend in the period from a beneficial conversion feature, exceeds basic earnings per share. The Convertible Preferred Stock was antidilutive at September 30, 2012 and 2011.

Also, under the if-converted method, convertible debt (such as the 3.25% Convertible Notes and the 6.00% Convertible Notes) is antidilutive whenever its interest per common share obtainable on conversion, including any deemed interest from a beneficial conversion feature and nondiscretionary adjustments, net of tax, exceeds basic earnings per share. At September 30, 2012, the 3.25% Convertible Notes and the 6.00% Convertible Notes were antidilutive. The 3.25% Convertible Notes were dilutive for the three and nine months ended September 30, 2011. Therefore, the shares of common stock obtainable on the assumed conversion of the 3.25% Convertible Notes, the interest expense and the amortization of discount, net of income tax, were included in the computation of diluted earnings per share for the corresponding periods.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Company’s net loss of $85.9 million for the nine months ended September 30, 2012 included $12.2 million in acquisition-related expense, which is a permanent difference between its loss for financial reporting and tax purposes. Molycorp had net deferred income tax liabilities of $162.3 million at September 30, 2012 primarily related to the purchase accounting adjustment associated with the Molycorp Canada acquisition.

At September 30, 2012, Molycorp determined that it, more likely than not, will realize its deferred tax assets and concluded that no valuation allowance is required. In making this determination, management analyzed, among other things, the Company’s recent history of earnings and cash flows, forecasts of future earnings, and the nature and timing of future deductions and benefits represented by the deferred tax assets and liabilities.

The Company has undistributed earnings for several foreign subsidiaries at September 30, 2012, for which deferred taxes have not been provided. Such earnings are considered indefinitely invested in the foreign subsidiaries. If such earnings were repatriated, additional tax expense may result, although the calculation of such additional taxes is not practicable.

The net tax effect of the elimination in consolidation of intercompany balances and transactions resulted in a deferred charge and income tax payable of $12.5 million at September 30, 2012.

Each quarter the Company evaluates the liability for uncertain tax positions. As a result of the acquisition of Molycorp Canada on June 11, 2012, some uncertain tax positions have decreased due to a lapse of the applicable statute of limitations, which totaled to $1.4 million, and some due to resolution with tax authorities for $13.7 million. These decreases have been recorded as a discrete income tax benefit in the third quarter of 2012. As a result of the statute of limitations that expire in the next 12 months in various jurisdictions, and possible settlements of audit-related issues with taxing authorities in various jurisdictions, the Company believes that it is reasonably possible that the total amount of its net unrecognized income tax benefits will decrease by approximately $4.0 million to $6.0 million in the next 12 months and, if recognized, would affect the Company's effective income tax rate.

Debt and Capital Lease Obligations

On August 22, 2012, the Company issued of $360.0 million aggregate principal amount of its 6.00% Convertible Senior Notes due 2017 (the “6.00% Convertible Notes”). On August 28, 2012, the underwriters of the 6.00% Convertible Notes exercised their option to purchase an additional $54.0 million aggregate principal amount of the 6.00% Convertible Notes. Total net proceeds from the issuance of the 6.00% Convertible Notes were $395.7 million, after deducting the underwriting discounts and commissions. Certain of the Company's directors, officers and other related parties purchased $6.4 million of the aggregate principal amount of the 6.00% Convertible Notes, for which the Company did not pay any underwriting discounts and commissions.

The 6.00% Convertible Notes are Molycorp's senior unsecured obligations with interest payable semi-annually in arrears on March 1 and September 1 of each year, commencing on March 1, 2013. The 6.00% Convertible Notes will mature on September 1, 2017, unless earlier repurchased, redeemed or converted in accordance with their terms, and will be convertible at any time prior to the second scheduled trading day immediately preceding the maturity date into shares of common stock, cash, or a combination thereof, at Molycorp's election. The conversion rate will initially be 83.333 shares of common stock per $1,000 principal amount of 6.00% Convertible Notes (equivalent to an initial conversion price of approximately $12 per share of common stock), subject to customary adjustments. Molycorp will have the right to redeem the 6.00% Convertible Notes on or after September 1, 2015 if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which Molycorp provides notice of redemption at a redemption price equal to 100% of the principal amount of the 6.00% Convertible Notes to be redeemed, plus accrued and unpaid interest. The 6.00% Convertible Notes rank equal in right of payment to existing and future liabilities that are not expressly subordinated to the 6.00% Convertible Notes, and rank effectively junior to Molycorp's existing and future secured indebtedness.

The Company separately accounts for the liability and equity components of convertible debt instruments, such as the 6.00% Convertible Notes, that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer's economic interest cost. The additional discount on the liability component is amortized to interest cost over the term of the 6.00% Convertible Notes. The effective interest rate on the liability component is 4.6%. The equity component of the 6.00% Convertible Notes is included in the additional paid-in capital section of stockholders' equity on the condensed consolidated balance sheet as of September 30, 2012, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component of the 6.00% Convertible Notes. As of September 30, 2012, Molycorp recognized a liability component related to the 6.00% Convertible Notes of $328.5 million, which includes a cumulative accretion of $1.5 million related to both the underwriting discounts and the additional discount on the liability component, and an equity component of $68.7 million. The amount of interest costs recognized for the three months ended September 30, 2012 relating to both the contractual interest coupon and amortization of the discount on the liability component was $3.8 million, which was substantially capitalized. Transaction costs related to the issuance of the 6.00% Convertible Notes have been allocated to the liability and equity components in proportion to the allocation of proceeds to the components, and accounted for as debt issuance costs (recognized as interest expense over the life of the 6.00% Convertible Notes using the effective interest method) and equity issuance costs (charged against equity), respectively.

Concurrently with, and in order to facilitate the offering of the 6.00% Convertible Notes, the Company entered into a share lending agreement with Morgan Stanley Capital Services LLC (“MSCS”), an affiliate of Morgan Stanley & Co. LLC, under which it agreed to loan to MSCS up to a total of 13,800,000 shares of its common stock (the “Borrowed Shares”)during a period beginning on the date the Company entered into the share lending agreement and ending on or about the maturity date of the 6.00% Convertible Notes, or, if earlier, on or about the date as of which all of the 6.00% Convertible Notes cease to be outstanding as a result of redemption, repurchase, conversion or other acquisition for value. MSCS may terminate all or any portion of the Borrowed Shares at any time, and the Company and MSCS may terminate any or all of the outstanding Borrowed Shares upon a default by the other party under the share lending agreement, including certain breaches by MSCS of its representations and warranties, covenants or agreements under the share lending agreement, or the bankruptcy of Molycorp or MSCS. The Company issued a total of 13,800,000 Borrowed Shares between August 22, 2012 and August 23, 2012 and received no proceeds, but only a nominal lending fee from MSCS for the use of these loaned shares, which represented the fair value assigned to it. For corporate law purposes, the Borrowed Shares are issued and outstanding. However, under the share lending agreement, MSCS has agreed: to pay to Molycorp an amount equal to cash dividends, if any, that Molycorp pays on the Borrowed Shares; to pay or deliver, as the case may be, to the Company any other distribution, other than in a liquidation or a reorganization in bankruptcy, that the Company makes on the Borrowed Shares; and not to vote on the Borrowed Shares on any matter submitted to a vote of Molycorp's stockholders. In view of the contractual undertakings of MSCS in the share lending agreement, which have the effect of substantially eliminating the economic dilution that otherwise would result from the issuance of the Borrowed Shares, the Borrowed Shares will not be considered outstanding for the purpose of computing and reporting Molycorp's earnings per share.

             On May 25, 2012, Molycorp issued $650.0 million aggregate principal amount of senior secured notes due 2020 (the "Senior Notes") in an offering exempt from the registration requirements of the Securities Act. Total net proceeds from the issuance of the Senior Notes were $635.4 million after deducting the initial purchasers' discounts. The Senior Notes bear interest at the rate of 10% per year payable on June 1 and December 1 of each year beginning on December 1, 2012. At any time and from time to time prior to June 1, 2016, the Company may redeem any of the Senior Notes at a price equal to 100% of the principal amount thereof plus an applicable make-whole premium and accrued and unpaid interest. At any time and from time to time from and after June 1, 2016, Molycorp may redeem the Senior Notes, in whole or in part, at a redemption price for the Senior Notes plus accrued and unpaid interest, initially at 105% of the principal amount thereof, but gradually declining to 100% of the principal amount thereof. In addition, at any time and from time to time prior to June 1, 2015, the Company may redeem up to 35% of the aggregate principal amount of the Senior Notes with the net cash proceeds of one or more permitted sales of Molycorp’s capital stock at a redemption price (expressed as a percentage of principal amount) of 110% plus accrued and unpaid interest. Upon the occurrence of a change of control, Molycorp will be required to offer to repurchase all of the Senior Notes. The Senior Notes are senior secured obligations of Molycorp and are guaranteed by certain of Molycorp’s domestic subsidiaries ("Guarantors"). The Senior Notes are secured by first-priority security interest on substantially all of the property and assets of the Company and the Guarantors, subject to a number of exceptions as described in the indenture governing the Senior Notes. A substantial portion of the net proceeds from the offering of the Senior Notes was used to fund the cash consideration the Company paid for Molycorp Canada, with the remainder used for general corporate purposes. The Company, the Guarantors and the initial purchasers of the Senior Notes agreed that the Company and the Guarantor will file an exchange offer registration statement with the SEC within 180 days of the May 25, 2012 issuance date, and use their respective commercially reasonable efforts to have it declared effective at the earliest possible time and in any event within 270 days following the issuance date.

As a result of the Molycorp Canada acquisition, the Company assumed $230.0 million principal amount of subordinated unsecured convertible debentures of the predecessor of Molycorp Canada due December 2017 (the “Debentures”) maturing on December 31, 2017. The Debentures bear interest at 5.00% per annum and are convertible at $13.80 per share of Molycorp Canada's predecessor company. As required under the change of control provisions contained in the original underlying indenture, holders of the Debentures had the option to either require the Company to repurchase the Debentures at par plus accrued interest, convert the Debentures into common shares of Molycorp Canada's predecessor company, including a number of additional “make-whole” shares, or hold the Debentures to maturity. In August 2012, holders of $9.4 million aggregate principal amount of Debentures elected to convert, while holders of $217.9 million aggregate principal amount of Debentures elected to early redeem their Debentures for cash plus accrued interest. Under the term of the indenture governing the Debentures, as amended at the time of the Molycorp Canada acquisition, the holders of the Debenture that converted received, at their election and in lieu of receiving shares of Molycorp Canada's predecessor company, the same cash and/or share consideration that was paid to Molycorp Canada's former shareholders in connection with the acquisition of Molycorp Canada, subject to the same pro-ration calculation, as if such holders had converted immediately prior to the acquisition. As a result of the conversion, a total of $8.0 million, including accrued interest, was paid in cash with the remainder converted into 99,723 shares of Molycorp common stock. Total interest cost related to the Debentures for the period from June 12, 2012 to September 30, 2012 was $0.6 million, inclusive of the interest accrued and paid upon the August 2012 repurchase. As of September 30, 2012, $2.7 million principal amount of the Debentures was outstanding.

Additional short-term indebtedness was assumed as part of the acquisition of Molycorp Canada totaling $31.5 million, at September 30, 2012, which relates to various bank loans maturing between July 2012 and December 2012 with a weighted average interest rate of approximately 4.22%.

On September 1, 2010, Molycorp and Kern River entered into a firm Transportation Service Agreement ("TSA") under which Kern River agreed to construct and operate facilities necessary to provide natural gas transportation services to the Mountain Pass facility. Under the terms of the TSA, Molycorp agreed to pay Kern River for the cost attributable to the design, permitting, and construction of the delivery facilities through a transportation service charge of approximately $0.4 million per month for ten years. This charge includes reimbursement to Kern River for construction of the delivery facilities and installation, as well as reimbursement and compensation for transportation services. The term of the TSA commenced on June 1, 2012, the date on which Kern River deemed the TSA facilities ready to provide service. The Company accounted for the TSA as a capital lease under the relevant accounting guidance.
