BUSINESS UPDATE

Overview

Our business is developing and monetizing as appropriate the remaining assets we received from the KSC bankruptcy. Following is a summary of our material assets other than cash and securities:

KAISER VENTURES LLC AND SUBSIDIARIES

We no longer own an interest in the West Valley MRF, LLC (“WVMRF, LLC”). On April 2, 2012, Kaiser Recycling, LLC, a wholly-owned subsidiary of Kaiser LLC, sold its fifty percent (50%) ownership interest in the WVMRF, LLC which owns and operates the West Valley Materials Recovery Facility and Transfer Station, a transfer station and materials recovery facility near Fontana, California. The gross cash sales price for Kaiser Recycling’s 50% ownership interest was approximately $25,769,000. The Company recorded a gain on the sale of $20,588,000 in the second quarter of 2012.

Cash Maximization Strategy Status

In September 2000, Kaiser Inc.’s Board of Directors approved a strategy to maximize the cash ultimately to be distributed to our owners taking into account all circumstances and applicable legal requirements. This strategy was continued with the conversion of Kaiser Inc. to a limited liability company at the end of 2001. Consistent with this strategy, Kaiser Inc. historically completed or entered into a number of transactions which resulted in Kaiser Inc. distributing a total of $12 per unit in cash to its shareholders. In particular the adverse final decision in the federal land exchange litigation in March 2011 negatively impacted MRC’s ability to pursue the Landfill Project, which in turn altered and adversely impacted the timing of the continuing implementation of the cash maximization strategy. However, with the sale by Kaiser Recycling of its ownership interest in the WVMRF, LLC, the Company’s Board of Managers declared and paid a distribution of $1.50 per Class A Unit to unitholders of record as of May 9, 2012. In addition, funds were reserved for known future liabilities and for possible future contingent liabilities. Further implementation of the cash maximization strategy and a further winding-down of the Company are dependent upon, among other things, the sale of its remaining assets, which the Company continues to pursue. The Company is also exploring options to further reduce its operating expenses.

Eagle Mountain Landfill Project and MRC

In 1988, the Company entered into a 100-year lease agreement (the “MRC Lease”) with MRC. MRC was seeking to develop the Company’s former iron ore mine near Eagle Mountain, California into a large, regional rail-haul, municipal solid waste landfill. On May 26, 2000, the Company also entered into a Real Estate Option Agreement (the “MRC Option”) with MRC which would permit MRC to acquire the real property for the Landfill Project upon the terms and conditions set forth in the MRC Option. The MRC Option has not yet been exercised and it currently expires on November 28, 2012, if it is not extended by mutual agreement. The Company currently owns approximately 84.247% of the Class B units and 100% of the Class A units of MRC. On October 30, 2011, MRC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy. For additional information, please see the discussion above under the first bullet point paragraph in “Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - BUSINESS UPDATE - Overview.”

KAISER VENTURES LLC AND SUBSIDIARIES

As part of the proceedings in Bankruptcy Court, MRC will need to develop a plan of reorganization which will include decisions regarding the status of the MRC Lease, the MRC Option and the Landfill Project Sale Agreement, among other things. In addition, MRC will consider and take action with respect to the proof of claims filed in the bankruptcy proceeding including whether to accept, reject, compromise or take other action with respect to any particular proof of claim that was timely and properly submitted. In addition, litigation and threatened litigation have arisen in the context of the MRC bankruptcy.

MRC Financing. Since Kaiser became an owner of MRC in 1995, MRC has been financed through a series of private offerings of securities to its existing equity owners. However, the Company has determined that it will not provide any future equity financing to MRC to pursue the Landfill Project, but MRC may need additional funds to complete its bankruptcy. Under certain circumstances, Kaiser LLC as well as others may become “debtor-in-possession” lenders to MRC. While Kaiser has made the determination that it will not provide future equity financing to MRC to pursue the Landfill Project, other non-related parties have expressed the desire to continue to pursue the Landfill Project in some manner.

West Valley Materials Recovery and Transfer Station

Background. WVMRF, LLC was formed in June 1997 by Kaiser Recycling Corporation (now Kaiser Recycling, LLC (formerly Kaiser Recycling, Inc.)), a wholly-owned subsidiary of Kaiser, and West Valley Recycling & Transfer, Inc., a wholly-owned subsidiary of Burrtec Waste Industries, Inc. (“Burrtec”). This entity was formed to construct and operate the materials recovery facility and is referred to as the WVMRF, LLC. This facility is permitted to receive up to 7,500 tons per day of municipal solid waste. Prior to April 2, 2012, the facility was processing approximately 3,000 – 3,500 + tons per day of municipal solid waste and recyclable materials.

Sale of Ownership Interest.As previously discussed in the Company’s Report on Form 10-Q for the quarter ended June 30, 2012,, Kaiser LLC, Kaiser Recycling, Burrtec Waste Industries (“Burrtec”) and West Valley Recycling & Transfer, Inc. (“WVRT”), a wholly owned subsidiary of Burrtec, entered into that certain Purchase Agreement (the “Purchase Agreement”) on April 2, 2012, whereby Kaiser Recycling sold its ownership interest in WVMRF, LLC to Buyer. The sale transaction closed on the same day as the Purchase Agreement was entered into by the parties to the agreement. Kaiser Recycling sold its ownership interest in WVMRF, LLC for a gross cash sales price of approximately $25,769,000. The Company recorded a gain of $20,588,000 in the second quarter of 2012. The Company’s guaranty of the outstanding California Pollution Control Finance Authority bonds was terminated. However, existing environmental obligations and agreements of the Company and Kaiser Recycling benefiting WVMRF, LLC, WVRT and Union Bank remain in place and an escrow of $363,000 was established as a part of the sale transaction to provide certain financial assurances, that we estimate will be sufficient to cover any future environmental obligations, particularly with respect to the Tar Pits Parcel located next to the WVMRF. This amount was charged against the Company’s environmental reserve which provided for such specific environmental expenses. Subsequently, an insurance policy covering certain possible contingent environmental and other related events that could arise and impact the WVMRF, LLC and others was purchased by Kaiser Recycling during the second quarter to cover certain of these exposures. The policy premium of $113,621 was paid from the escrow account. (See also, “Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION - Financial Position -Environmental Remediation.”)

Distribution.A cash distribution of $750,000 was received from the WVMRF, LLC during the first quarter of 2012. As a result of the sale by Kaiser Recycling of its ownership interest in WVMRF as April 2, 2012, no further cash distributions will be received from WVMRF, LLC.

KAISER VENTURES LLC AND SUBSIDIARIES

OPERATING RESULTS

Note on WVMRF, LLC

Due to the sale of our fifty percent (50%) ownership in WVMRF, LLC on April 2, 2012, the Company’s consolidated financial statements for the third quarter of 2012 do not reflect any operating results of WVMRF, LLC. However, the consolidated financial statements for the nine months ended September 30, 2012 and 2011 do reflect our fifty (50%) ownership interest in WVMRF, LLC for the four month period from December 1, 2011 to April 2, 2012 (date of transaction), as compared to the nine months ended August 31, 2011. This is due to the time required to close the books of the WVMRF, LLC and in keeping with past practice, there is a one month delay in reporting the results of WVMRF, LLC.

Summary of Revenue Sources

Due to the nature of the Company’s projects and the Company’s recognition of revenues from non-recurring items, historical period-to-period comparisons of total revenues may not be meaningful for developing an overall understanding of the Company. Therefore, the Company believes it is important to evaluate the recent developments regarding its revenue sources.

Results of Operations

Analysis of Results for the Quarters Ended September 30, 2012 and 2011

Revenues. Total revenues for the third quarter of 2012 were $214,000 as compared to $645,000 for the comparable period in 2011. The reasons for this decrease are discussed below.

Revenue from the Company’s equity method investment in the WVMRF, LLC decreased by $588,000 to $0 for the third quarter of 2012 as compared to $588,000 for the same period in 2011. This decrease is the direct result of the sale of our entire member interest in the West Valley MRF on April 2, 2012. As a result of the sale, the third quarter operating results for the Company in 2012 do not include any equity income related to the West Valley MRF as mentioned under “Note on WVMRF” above.

Revenue from Eagle Mountain operations increased for the third quarter of 2012 by $157,000 to $214,000 as compared to $57,000 for 2011, primarily due to increased revenue from rock and aggregate sales, as well as, increased water and gas & diesel sales as compared to the same period in 2011.

Operating Costs. Operating costs decreased to $502,000 for the third quarter of 2012 from $548,000 for the same period in 2011. This decrease relates primarily to decreased expenses for machinery maintenance of $15,000, legal of $29,000, outside services of $10,000, and consulting of $37,000, which were partially offset by increased gas and diesel costs of $51,000. Some of these expenses were rebilled to customers buying rock and aggregate.

Corporate General and Administrative Expenses.Corporate general and administrative expenses increased to $567,000 for the third quarter of 2012 from $467,000 for the same period in 2011. This increase is primarily related to increases in accrued bonuses of $22,000, a reduction in allocated salaries-out of $83,000 related to the sale of our interest in the West Valley MRF, and increases in legal expenses of $32,000, which were partially offset by a reduction in outside advisor expenses of $26,000 and communication expenses of $7,000.

Net Interest and Investment Income. Net interest and investment income, for the third quarter of 2012, was a gain of $20,000 compared to a loss of $123,000 for the same period in 2011. Of the $20,000 gain for the third quarter of 2012, $24,000 was interest income, which was offset by a $4,000 net unrealized loss on the Company’s short-term investments.

KAISER VENTURES LLC AND SUBSIDIARIES

Income/(Loss) Before Income Tax Benefit and Allocation of Non-Controlling Interest. The Company recorded a pre-tax loss of $835,000 in the third quarter of 2012 versus a pre-tax loss of $493,000 for the same period in 2011. The Company is taxed as a partnership and thus the Company’s annual results of operations (on an income tax basis) are allocated to the unit holders for inclusion in their respective income tax returns.

Net Income/(Net Loss) Attributable to Controlling Interest.For the third quarter of 2012, the Company reported a net loss attributable to controlling interest of $821,000, which is equal to $0.12 per unit, versus a loss of $438,000, or $0.06 per unit for the same period in 2011.

Analysis of Results for the Nine Months Ended September 30, 2012 and 2011

Revenues. Total revenues for the first nine months of 2012 were $1,095,000, compared to $1,814,000 for 2011. The reasons for this decrease are discussed below.

Revenue from the Company’s equity method investment in the West Valley MRF decreased by $1,299,000 to $391,000 as compared to $1,690,000 for 2011. This decrease is the direct result of the sale of our entire member interest in the West Valley MRF on April 2, 2012. As a result of the sale, the nine month’s operating results for the Company in 2012 only include the months December 2011 through March 2012 for the West Valley MRF as mentioned above under “Note on WVMRF”.

Revenue from Eagle Mountain operations for the first nine months of 2012 increased by $580,000 to $704,000 as compared to $124,000 for 2011. This increase is primarily due to increased revenue from rock and aggregate, water, and gas and diesel sales, and tenant rentals as compared to the same period in 2011.

Operating Costs. Operating costs decreased to $1,784,000 for the first nine months of 2012 from $8,060,000 for the same period in 2011. This decrease relates primarily to the $6,683,000 write-down of MRC’s investment in the Eagle Mountain Landfill project during the same period in 2011. Excluding this write-down, operating costs actually increased by $407,000, primarily related to increased expenses relating to machinery and electrical maintenance and supplies of $135,000; bulk fuel purchases of $118,000; licenses, fees and permits of $38,000; and legal, outside services and consultants of $84,000. Some of these expenses were rebilled to customers buying rock and aggregate.

Corporate General and Administrative Expenses.Corporate general and administrative expenses increased to $3,016,000 for the first nine months of 2012 from $1,471,000 for the same period in 2011. This increase is primarily related to the payment of bonuses and C and D Unit compensation expense of $296,000 and $771,000, respectively, which were triggered by the Company’s entire member interest in the sale of the West Valley MRF, LLC, plus $131,000 in expenses relating to employee severance. In addition, during 2012, there was an increase in legal expenses related to the MRC bankruptcy of $169,000, an increase in retirement plan expenses related to the use of previously forfeited funds at Fidelity Investments of $49,000, and, as a result of the sale of our interest in the West Valley MRF, LLC, an increase in the net compensation expense of $166,000, which amount would have been previously billed to and reimbursed by the West Valley MRF, LLC.

Gain on Sale of Investment in West Valley MRF, LLC. The Company recorded a gain of $20,588,000 from the sale of its 50% member interest in West Valley MRF, LLC on April 2, 2012.

Net Interest and Investment Income. Net interest and investment income, including unrealized gains of $112,000, for the first nine months of 2012, was a gain of $72,000 compared to a gain of $12,000 for the same period in 2011. Of the $72,000 gain for the first nine months of 2012; $60,000 relates to interest income, and $12,000 relates to net realized and unrealized gains on the Company’s short-term investments.

KAISER VENTURES LLC AND SUBSIDIARIES

Income/(Loss) Before Income Tax Provision and Allocation of Non-Controlling Interest. The Company recorded pre-tax income of $16,955,000 in the first nine months of 2012 versus a pre-tax loss of $7,705,000 for the same period in 2011. The Company is taxed as a partnership and thus the Company’s annual results of operations (on an income tax basis) are allocated to the unit holders for inclusion in their respective income tax returns. There are, however: (a) federal income taxes imposed on the Company’s Business Staffing Inc. subsidiary and; (b) a gross revenue tax imposed by the State of California.

Net Income/(Net Loss) Attributable to Controlling Interest.For the first nine months of 2012, the Company earned net income of $17,002,000, or $2.43 per unit, versus a loss of $6,465,000, or $0.95 per unit for the same period in 2011.

FINANCIAL POSITION

Cash, and Cash Equivalents and Short-Term Investments. The Company defines cash equivalents as highly liquid debt instruments with original maturities of 90 days or less. Cash and cash equivalents increased $5,960,000 to $6,764,000 at September 30, 2012 from $804,000 at December 31, 2011. Included in cash and cash equivalents is $237,000 and $534,000 held solely for the benefit of MRC at September 30, 2012 and December 31, 2011, respectively.

Below is a table showing the major changes in cash during 2012:

Working Capital. During the first nine months of 2012, current assets increased by $11,083,000 to $15.5 million, while current liabilities decreased $39,000 to $2,192,000. The increase in current assets was the result of (a) an increase in cash and equivalents as discussed above; (b) an increase in accounts receivable and other of $162,000; (c) an increase in restricted cash of $32,000; and (d) an increase in short term investments of $4,929,000. The decrease in current liabilities is the result of a decrease of $186,000 in accounts payable offset by an increase in accrued liabilities of $147,000. As a result, net working capital increased during the first nine months of 2012 by $11,122,000 to $13,303,000 at September 30, 2012.

Below is a table showing the major changes in working capital.

Accounts Receivable and Other (Net). During the first nine months of 2012, accounts receivable and other current assets increased by $162,000 primarily due to increases in trade accounts receivable associated with aggregate sales at Eagle Mountain and prepaid insurance.

KAISER VENTURES LLC AND SUBSIDIARIES

Short-Term Investments. During the first nine months of 2012, short-term investments increased by $4,929,000. This is the result of increased investment activity utilizing a portion of the funds from the sale of the West Valley MRF. On September 30, 2012, the Company had $7.6 million of its excess cash reserves invested in such investments. Investments are marked to market and unrealized earnings or loss are reflected in the value of the investment and in income for the period for which they are earned. A vast majority of the invested cash is being reserved for future potential liabilities and commitments.

Investments. The Company’s equity share of income from the investment in the West Valley MRF, which totaled $391,000 for the first nine months of the year, was offset by the receipt of cash distributions totaling $750,000 resulting in a $359,000 decrease to the Company’s investment in the West Valley MRF. In addition, the Company sold its entire member interest in the West Valley MRF, LLC on April 2, 2012, so the Company’s investment in the West Valley MRF, LLC was $0 at September 30, 2012.

As previously stated, the investment in the MRC Landfill Project was determined to be impaired and, therefore, was written-down by $6,683,000 during the first quarter of 2011 which was charged to earnings. As required by the ASC, all subsequent Eagle Mountain Landfill expenses will be expensed as incurred.

Other Assets. For the first nine months of the year, there was a decrease in other assets of $235,000 which is the net result of the amortization of the environmental insurance policy of $225,000, and depreciation of $10,000 related to buildings and equipment.

Environmental Remediation. The Company purchased, in 2001, a 12-year $50 million insurance policy to cover substantially any and all environmental claims (up to the $50 million policy limit) relating to the historical operations of the Company. As of September 30, 2012, based upon current information, we estimate that our future environmental liability related to certain matters and risks not assumed by CCG Ontario, LLC, a subsidiary of Prologis, in its purchase of the Mill Site Property in August 2000 would be approximately $2.3 million for which a reserve has been established. See “Note 2. - ENVIRONMENTAL MATTERS”. In the event a claim for damages is filed against the Company that relates to this reserve, management believes that the claim may be covered by insurance depending upon the nature and timing of the claim. In addition, in connection with the Tar Pits Parcel now owned by Kaiser Recycling, LLC, insurance was purchased in the second quarter of this year to cover possible contingent environmental related liabilities and a third party escrow of $363,000 in cash was established benefitting WVMRF, LLC and others. This amount was charged against the Company’s environmental reserve which encompassed this specific environmental exposure. The $113,621 premium for the purchased policy was paid from the cash escrow.

Non-Controlling Interest in MRC. During the first nine months of 2012, the Non-Controlling Interest decreased by $53,000 from $2,057,000 as of December 31, 2011 to $2,004,000 as of September 30, 2012, which is the net loss attributable to non-controlling interest for the nine month period. As of September 30, 2012 the resulting non-controlling interest is $2,004,000, which relates to the approximate 15.8% ownership interest in MRC that the Company does not own.

Contingent Liabilities. The Company has contingent liabilities more fully described above and in the notes to the financial statements.

Critical Accounting Policies

The Company’s accounting policies are more fully described in the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. As disclosed in the Notes to the 2011 Annual Financial Statements, the preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions about future events that affect the amounts reported in the consolidated financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty and therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the consolidated financial statements.

KAISER VENTURES LLC AND SUBSIDIARIES

The Company believes the following critical accounting policies, which comply with the ASC, are important to the portrayal of the Company’s financial condition and results.

Investments. The Company accounts for investments under Section 320-10 of the ASC. The Company invests its excess cash reserves in investment grade or better commercial paper (Standard & Poor’s rating of “A” or above), and U.S. government bonds which it classifies as “available-for-sale” and which are recorded at the purchase price of the security plus or minus the discount or premium paid. Investments are marked to market and unrealized earnings are reflected in income for the period in which they are earned. However, the Company expects to hold these investments to maturity.

Investment in West Valley MRF, LLC. The Company accounted for its investment in WVMRF, LLC, under the equity method of accounting because of the Company’s 50% non-controlling ownership interest. However, as discussed elsewhere in this Report, the Company’s ownership interest in WVMRF, LLC was sold on April 2, 2012.

Landfill Permitting and Development. Through its 84.247% interest in MRC, the Company has been developing, for sale to a municipal entity or operating company, its property known as the Eagle Mountain Site in the California desert for use as a rail-haul municipal solid waste landfill. Pursuant to Section 970-10 of the ASC, capitalizable landfill site development costs are recorded at cost and will be expensed when management determines that the capitalized costs provide no future benefit. However, as discussed in more detail in this Report on Form 10-Q, effective June 30, 2010 and March 31, 2011, there was a determination of impairment of MRC’s investment in the Eagle Mountain Landfill Project which resulted in write-downs of the carrying amount of such investment in our financial statements. With the determination that an impairment exists no further costs have been or will be capitalized.

Environmental Insurance and Environmental Remediation Liabilities. The Company’s $3.8 million premium for the prospective insurance policy, which was reduced by a refund from the insurance carrier, is capitalized as a long-term asset and is being amortized on a straight-line basis over the twelve (12) year term of the policy. To the extent a pre-existing liability has not been recorded, claims made for environmental matters are recorded as litigation accruals in the Company’s consolidated financial statements pursuant to Section 450-10 of the ASC when it becomes probable that a loss has been incurred and the amount of such loss can be reasonably estimated. Claims accepted by the insurance company pursuant to coverage under the policy are recorded as insurance receivables when coverage is accepted and the amount to be paid by the insurance company can be reasonably estimated. In addition, a new limited environmental insurance policy for a ten year term was purchased by Kaiser Recycling as more fully discussed in “WEST VALLEY MRF AND TRANSFER STATION - Sale of Ownership Interest” above.

Revenue Recognition. Revenues are recognized when the Company has completed the earnings process and an exchange transaction has taken place.

Conditional Asset Retirement Obligations. The Company accounts for certain asset retirement obligations at Eagle Mountain pursuant to ASC 410Accounting for Asset Retirement and Environmental Obligations.

Long-Lived Assets. In accordance with Section 360 of the ASC, long-lived assets are evaluated for potential impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. As discussed in more detail in this Report of Form 10-Q, effective June 30, 2010 and March 31, 2011, there were determinations of impairment of the Eagle Mountain Landfill investment, a long-lived asset, which resulted in write-downs of the carrying amount of such investment in our financial statements.

KAISER VENTURES LLC AND SUBSIDIARIES

BUSINESS OUTLOOK

The statements contained in this Business Outlook, as well as in “Part I - Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - Overview”, are based upon current operations and expectations. In addition to the forward-looking statements and information contained elsewhere in this Report on Form 10-Q, these statements are forward-looking and, therefore, actual results may differ materially. See the Company’s disclosure regarding forward-looking statements in the section entitled “Forward-Looking Statements” above.

Ongoing Operations. As noted above, our revenues from ongoing operations have, in the past, generally been derived from the performance of our major long-term development projects and investments. We have sold most of our major projects and investments as we have disclosed in previous SEC filings, and as previously discussed in this report, on April 2, 2012, we sold our fifty percent (50%) ownership interest in WVMRF, LLC. Accordingly, our principal remaining assets and projects, other than cash and securities, are: (i) our ownership interest in MRC, however, MRC filed a voluntary bankruptcy petition under Chapter 11 of the U.S. Bankruptcy Code on October 30, 2011; (ii) our 100% equity ownership of KEM which owns and controls approximately 10,000 acres at the Eagle Mountain Site on or in which millions of tons of iron ore, stockpiled rock and other mineral resources are present; and (iii) our 100% equity ownership interest in Lake Tamarisk Development which owns property near the Eagle Mountain Site. We have no material ongoing operations except in connection with such remaining assets and projects and in connection with addressing any liabilities we may have. Our principal sources of ongoing income over the last several years have been derived from the WVMRF, LLC, investment earnings and from miscellaneous income generated at the Eagle Mountain Site. As a result of the sale of our interest in WVMRF, LLC, no further equity income will be received from WVMRF, LLC.

MRC. As discussed in more detail in “Part I - Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - BUSINESS UPDATE - Overview,” on October 30, 2011, MRC filed a voluntary petition in bankruptcy pursuant to Chapter 11 of the U.S. Bankruptcy Code. The filing was necessary to protect and preserve MRC’s assets and options. Depending upon the results of the bankruptcy process, it is possible that the value of Kaiser’s investment in MRC could be further impaired.

Mill Site Property. The only remaining Mill Site Property owned is an approximate five acre parcel referred to as the Tar Pits Parcel which is now owned by Kaiser Recycling. CCG Ontario, LLC substantially completed all material environmental remediation of this parcel pursuant to the terms of its agreement during 2002. CCG Ontario does have ongoing operations and maintenance obligation with respect to the Tar Pits Parcel. WVMRF, LLC has the right to purchase the Tar Pits Parcel for $1.00. Effective April 2, 2012, WVMRF, LLC leased material portions of the Tar Pits Parcel from Kaiser Recycling. The lease is for 50 years with the right to extend the lease for 50 years in exchange for: (i) payment of all the property taxes for the Tar Pits Parcel; (ii) insuring the Tar Pits Parcel and naming Kaiser Recycling as an additional insured for general liability purposes; and (iii) performing various maintenance and security obligations on the property being leased. In addition, a cash escrow was established in the amount of $363,000 benefiting WVMRF, LLC and others in connection with possible contingent environmental and environmental related actions, a reserve for which had been previously recorded. A limited environmental insurance policy with a term of ten years was purchased for $113,621 with the policy premium being paid from the escrowed amount.

Cash Maximization Strategy. In September 2000, Kaiser Inc.’s Board of Directors approved a strategy to maximize the cash ultimately to be distributed to our owners taking into account all circumstances and applicable legal requirements. This strategy was continued with the conversion of

KAISER VENTURES LLC AND SUBSIDIARIES

Kaiser Inc. to a limited liability company at the end of 2001. Consistent with this strategy, Kaiser Inc. historically completed or entered into a number of transactions which resulted in Kaiser Inc. distributing a total of $12 per unit in cash to its shareholders. Lengthy, but adversely completed, litigation involving the Landfill Project delayed the implementation of the goals of the cash maximization strategy. In particular the adverse final decision in the federal land exchange litigation in March 2011 negatively impacted MRC’s ability to pursue the Landfill Project, which in turn altered and adversely impacted the timing of the continuing implementation of the cash maximization strategy. However, with the sale by Kaiser Recycling of its ownership interest in WVMRF, LLC, the Company’s Board of Managers declared and paid a distribution of $1.50 per Class A Unit to unitholders of record as of May 9, 2012. In addition, funds were reserved for known future liabilities and for possible future contingent liabilities. Further implementation of the cash maximization strategy and a further winding-down of the Company’s investment in MRC are dependent upon, among other things, other asset sales. The Company is also exploring its options to further reduce its operating expenses.

Corporate Overhead. With the sale of our ownership interest in WVMRF, LLC, there was a reduction during the second quarter in the staffing of the Company’s accounting department to reflect the reduced requirements resulting from the sale of our interest in WVMRF, LLC and of our remaining operations and projects. The costs of such reductions, including the payment of severance, were recorded during the second quarter of 2012.

Capital Resources. Kaiser LLC expects that its current cash balances and short-term investments together with cash generated from current and future asset sales as well as expense reductions will be sufficient to satisfy the Company’s ongoing projected operating cash requirements for at least the next twelve months.

MRC Bankruptcy. On October 30, 2011, MRC filed a voluntary petition relief under Chapter 11 of the U.S. Bankruptcy Code. MRC continues to operate as a debtor in possession. MRC’s bankruptcy is not currently expected to have a material direct adverse result on Kaiser except that Kaiser will incur attorneys’ fees and costs as a result of the bankruptcy and Kaiser may elect to become a debtor-in-possession lender to MRC to provide the funds necessary to complete the bankruptcy process.

As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-14.

Based on its review of the Company’s disclosure controls and procedures, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Company (including its subsidiaries) that is required to be included in the Company’s periodic Securities and Exchange Commission filings. Specifically, since 2007, the Company has: (a) requested annually that all of the critical employees, officers and Members of the Board of Managers of the Company complete an extensive internal control and risk management questionnaire; and (b) internally reviewed and tested the implementation of its internal controls against the Company’s written control procedures. The above conclusions are based upon the work performed. Additionally,There were no significant changes in internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses. However, with the termination of two accounting positions due to the sale of Kaiser Recycling, Inc.’s ownership interest in WVMRF, LLC, including the termination of the Company’s controller position as of June 30, 2012, going forward there will be fewer individuals that will be able to review and correct any

KAISER VENTURES LLC AND SUBSIDIARIES

omission or errors that may occur in the Company’s accounting controls and procedures. The effect of this will be mitigated by the part-time employment of the now retired former controller and expanded oversight of the detailed accounting functions by the Company’s Chief Financial Officer and General Counsel. As previously noted, the effectiveness of the Company’s disclosure controls and procedures are evaluated effective as of the end of each calendar quarter.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

The unaudited consolidated financial statements of Kaiser Ventures LLC and Subsidiaries (the “Company”) as of September 30, 2012 and 2011, as well as the related notes, should be read in conjunction with the Company’s audited consolidated financial statements and related notes as of and for the year ended December 31, 2011, included in the Company’s Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the Company’s financial position at September 30, 2012, and results of operations and cash flows for the nine month period ended September 30, 2012 and 2011.

The Company’s consolidated financial statements include the following significant entities: Lake Tamarisk Development, LLC; Kaiser Eagle Mountain, LLC; Kaiser Recycling LLC; all of which are 100% owned; and Mine Reclamation, LLC, which is 84.247% owned.

In addition, the Company has determined that Business Staffing, Inc. which provides administrative services to the Company, is a variable interest entity due to a lack of sufficient equity at risk even though the Company does not own any interest in Business Staffing, Inc. which is 100% owned by three officers of the Company. The Company has also determined it is the primary beneficiary of Business Staffing, Inc. because the Company has the power to direct activities that most significantly impact the economic performance of Business Staffing, Inc. Accordingly, the Company has consolidated this entity into the consolidated financial statements. The consolidation of this entity does not change any legal ownership, and does not change the assets or the liabilities and equity of Kaiser Ventures LLC and Subsidiaries as a stand-alone entity. Total assets of the variable interest entity were $2,556,000 and $0 as of September 30, 2012 and December 31, 2011, respectively. All intercompany accounts and transactions have been eliminated on consolidation.

Kaiser is the reorganized successor to Kaiser Steel Corporation, referred to as KSC, which was an integrated steel manufacturer that filed for bankruptcy protection in 1987. Since KSC’s bankruptcy, we have been developing assets remaining after the bankruptcy and have realized substantial value from certain of those assets. Currently, our principal remaining assets are: (i) our 84.27% ownership interest in MRC, however, MRC filed a voluntary bankruptcy petition under Chapter 11 of the U.S. Bankruptcy Code on October 30, 2011; (ii) our 100% equity ownership of KEM which owns and controls approximately 10,000 acres at the Eagle Mountain Site on or in which millions of tons of iron ore, stockpiled rock and other mineral resources are present; and (iii) our 100% equity ownership interest in Lake Tamarisk Development which owns property near the Eagle Mountain Site

Our 50% ownership interest in the West Valley MRF, LLC was sold on April 2, 2012. For further information on this transaction, see “Note 5. INVESTMENT IN WEST VALLEY MRF, LLC.”

The Company purchased an insurance policy effective June 30, 2001 that is designed to provide broad prospective commercial general liability, pollution legal liability, and contractual indemnity coverage for the Company’s ongoing and historical operations. The policy has a twelve (12) year term and limits of $50 million in the aggregate for defense and indemnity, with no deductible or self-insured retention. The policy is designed to provide coverage for future claims in excess of the Company’s existing and historic insurance policies; however, to the extent that these other insurance policies are not responsive to a claim, the policy will provide first dollar coverage for a claim resulting from property damage, personal injury, bodily injury, cleanup costs or violations of environmental laws. The policy also provides for a broad defense of claims that may be brought against the Company. The policy is specifically intended to provide additional coverage for potential liabilities arising from pollution conditions or known and/or potential asbestos-related claims. The policy also provides contractual

KAISER VENTURES LLC AND SUBSIDIARIES

indemnity coverage for scheduled indemnity obligations of the Company arising from, e.g., prior corporate transactions and real estate sales. The Company expects this policy will cover substantially any and all environmental claims (up to the $50 million policy limit) relating to the historical operations of the Company.

The aggregate cost for this policy was approximately $5.8 million, of which, based upon discussions among the respective members of the Boards of Directors, KSC Recovery paid $2 million and the Company paid the balance of approximately $3.8 million. The portion of the policy paid by KSC Recovery was expected to cover known and/or potential asbestos claims; while the portion of the policy paid by the Company was expected to cover future potential claims arising from the Company’s historical operations.

The Company’s original $3.8 million premium for the prospective insurance policy was capitalized as a long-term asset and is being amortized on a straight-line basis over the 12 year term of the policy. To the extent a pre-existing liability has not been recorded, claims made for environmental matters are recorded as litigation accruals in the Company’s consolidated financial statements pursuant to Section 450-10 of the ASC when it becomes probable that a loss has been incurred and the amount of such loss can be reasonably estimated. Claims accepted by the insurance company pursuant to coverage under the policy are recorded as insurance receivables when coverage is accepted and the amount to be paid by the insurance company can be reasonably estimated. Generally, unless previously accrued, the liability and the receivable relating to claims covered by this policy should occur in the same accounting period, thereby having no adverse or beneficial impact on the Company’s operating results for that accounting period.

In addition to the foregoing policy, an additional insurance policy with a term of ten years covering certain possible contingent environmental and other related events that could arise and impact the West Valley MRF, LLC and others was purchased by Kaiser Recycling during the second quarter. The policy premium of $113,621 was paid from the escrow account originally totaling $363,000 that was established as a result of the sale of Kaiser Recycling, LLC’s ownership interest in WVMRF, LLC. The amount of this escrow was charged against the Company’s existing environmental liability reserve.

The Company has an Investment Policy which provides for the investment of excess cash balances primarily in bond funds, commercial paper, and debt instruments. At September 30, 2012 the Company had all of its investments in bonds, bond funds or high grade commercial paper (Standard & Poor’s rating of “A” or above) which are classified as “available-for-sale.”

Pursuant to Section 825-10 of the ASC, the Company at the end of a period, compares the actual market value to the actual cost and uses that calculation to determine any gain or loss on the maturity or sale of each available-for-sale investment.

The following is a summary of the fair value of investment securities classified as “available-for-sale” as of September 30, 2012 and December 31, 2011. For each item included in the table below the gains or losses from Fair Value reporting are included in income for the quarter.

KAISER VENTURES LLC AND SUBSIDIARIES

ASC 825-10 defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. ASC 825-10 establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 825-10 establishes three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement.

Our short and long-term investments in commercial paper and bonds represent available-for-sale securities that are valued primarily using quoted market prices utilizing market observable inputs in active markets for identical assets.

The following table presents information about our assets measured at fair value on a recurring basis at September 30, 2012 and December 31, 2011, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

KAISER VENTURES LLC AND SUBSIDIARIES

In addition to the assets listed in the table, other short-term financial assets and liabilities of the Company consist of accounts receivable, accounts payable and certain accrued liabilities. These financial assets and liabilities generally approximate fair market value based on their short-term nature.

On April 2, 2012, Kaiser Recycling, LLC sold its 50% ownership interest in the West Valley MRF, LLC which owns and operates the WVMRF, a transfer station and materials recovery facility near Fontana, California. The gross cash sales price for the 50% ownership interest was approximately $25,769,000. The Company recorded a gain on the sale of $20,588,000 in the second quarter of 2012. Existing environmental obligations of the Company and Kaiser Recycling benefiting West Valley MRF, LLC and West Valley Recycling & Transfer, LLC (the owner of the other 50% interest in the West Valley MRF and the buyer of Kaiser Recycling’s ownership interest in the West Valley MRC, LLC) remain in place. An escrow originally totaling $363,000 was established to provide certain additional financial assurances for the Company’s and Kaiser Recycling, Inc.’s existing contingent environmental obligations. The amount of this escrow was charged against the Company’s existing environmental reserve. Kaiser Recycling, LLC purchased an environmental insurance policy for $113,621 which was paid from the escrow account, leaving a balance of $249,379 in the escrow account. In addition, the Company’s guaranty of certain outstanding debt of West Valley (approximately $5,820,000 as of March 31, 2012) was terminated. Finally, as a result of the sale of the Company’s member interest in West Valley MRF, LLC on April 2, 2012, the Company will no longer be providing and billing West Valley MRF, LLC for accounting services from that date, which totaled approximately $28,000 per month or approximately $84,000 per quarter. The Company also reduced its accounting staff by one employee as of June 30, 2012 and recorded severance expenses associated with that termination of $131,000 during the second quarter of 2012.

With the completed sale of the ownership interest in West Valley MRF, LLC, compensation related actions were implemented under the previously disclosed terms of applicable compensation arrangements for officers and under the terms of the Company’s Class C and D Units. In accordance with the terms and conditions of the Company’s Class C and D Units $771,000 was due and paid on such units. In addition, a bonus of approximately $173,000 was paid to an officer in accordance with the terms of his employment agreement. The Company also awarded $95,000 in discretionary bonuses as a result of the sale of the ownership interest in the West Valley MRF. In addition, a “Change in Control” occurred under the terms of the Amended and Restated Services Agreement, as amended, between the Company and Business Staffing, Inc. and under the terms of the employment agreement of each executive officer.

KAISER VENTURES LLC AND SUBSIDIARIES

The Company accounted for its investment in West Valley MRF, LLC under the equity method.

Due to the time required to close the books of the West Valley MRF, LLC and in keeping with past practice, there was a one month delay in reporting the results of West Valley MRF, LLC. Thus, even though the closing on the sale of Kaiser Recycling, LLC’s ownership interest occurred on April 2, 2012, due to this one month delay, there was one month’s of the Company’s share of the income for West Valley MRF, LLC during the second quarter of 2012. The condensed summarized financial information of West Valley MRF, LLC is as follows:

The Company recognized equity income from the West Valley MRF, LLC of $1,690,000 for the first nine months of 2011, and $391,000 for the period from December 1, 2011 to April 2, 2012 (date of transaction).

In accordance with Section 360 of the ASC, long-lived assets are evaluated for potential impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Our reviews as of September 30, 2012, concluded that no impairment had occurred and other real estate and building and equipment are recorded at the lower of cost or fair market values.

With the denial of our appeal to the U.S. Supreme Court, our quarterly analysis pursuant to the ASC of whether the MRC investment in Eagle Mountain Landfill Project was impaired, resulted in a determination of impairment and a write-down of the carrying amount of the MRC investment in Eagle Mountain Landfill Project as of March 31, 2011. As required by GAAP, the impairment determination and resulting calculation of fair value of the carrying amount of the MRC investment in Eagle Mountain Landfill Project were made utilizing a probability analysis of the remaining options with regard to the Landfill Project after the U.S. Supreme Court declined to accept the petition requesting further review of the adverse U.S. 9^th Circuit Court of Appeals decision as of March 28, 2011. The total amount of the write-down was $6,683,000 which was charged to earnings in the first quarter of 2011. As of September 30, 2012, there were no events or changes in circumstances that indicated that the carrying amount of MRC’s investment in Eagle Mountain Landfill Project may not be recoverable. Possible further impairment in the MRC investment in Eagle Mountain Landfill Project resulting from MRC’s bankruptcy filing on October 30, 2011, may be required in the future as the impact of the bankruptcy filing is determined.

Environmental Contingencies. As discussed in Note 2, effective June 30, 2001, the Company purchased a 12-year $50 million insurance policy which is expected to cover substantially any and all environmental claims (up to the $50 million policy limit) relating to the historical operations of the Company. To the extent a pre-existing liability has not been recorded, claims made for environmental matters are recorded as litigation accruals in the Company’s consolidated financial statements pursuant to ASC 450-10 when it becomes probable that a loss has been incurred and the amount of such loss can be reasonably estimated. Claims accepted by the insurance company pursuant to coverage under the policy are recorded as insurance receivables when coverage is accepted and the amount to be paid by the insurance company can be reasonably estimated.

KAISER VENTURES LLC AND SUBSIDIARIES

As of September 30, 2012, the Company estimates, based upon current information and discussions with environmental consultants, that its future environmental liabilities related to certain matters not assumed by CCG Ontario, LLC in its purchase of a substantial portion of Kaiser’s former Fontana mill site property (“Mill Site Property”), including a certain groundwater matter as well as potential matters at Eagle Mountain and at other historical locations, will be approximately $2.3 million. In the event that a future environmental claim for damages is filed against the Company such claim may be covered by insurance depending upon the nature and timing of the claim.

In addition, an insurance policy covering certain possible contingent environmental and other related events that could arise and impact the WVMRF and others subsequent to the sale of the Company’s interest in the WVMRF was purchased by Kaiser Recycling during the second quarter. The policy premium of $113,621 was paid from the existing escrow account established by the Company at the time of the sale. These potential contingent environmental related events for which insurance coverage was purchased existed regardless of the sale of Kaiser Recycling’s ownership interest in WVMRF, LLC but such sale did accelerate the timing on fully addressing such potential contingent liabilities.

MRC Financing. Since Kaiser became an owner of MRC in 1995, MRC has been financed through a series of private placements to its existing equity owners. As a result of a private placement completed in September 2011, MRC raised total proceeds of approximately $1,300,000, of which amount Kaiser contributed $1,146,344, which increased Kaiser’s ownership interest in MRC from 83.13% to 84.247%.

Contingent Compensation Expense on Class B, C and D Units. Upon the sale of certain of the Company’s assets at a price equal to or greater than certain minimum sales prices, additional compensation payments will be made on the Class B, C and D Units in accordance with their respective terms. With the sale of Kaiser Recycling, LLC’s ownership interest in West Valley MRF, LLC, compensation payments totaling $771,000 were due and paid during the second quarter of 2012 in accordance with the terms and conditions of the Company’s Class C and D Units.

Restricted Cash.Restricted Cash consists primarily of certificates of deposit used to secure certain letters of credit that provide indemnification to governmental entities regarding landfill project approvals and mining rights and other mine related matters. During the second and third quarters of 2012 additional certificates of deposit in the amount of $32,000 were acquired to amend the indemnification to the County of Riverside.

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the company’s consolidated financial statements upon adoption.

In June 2011, the FASB issued guidance regarding the presentation of comprehensive income. The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The new standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The updated guidance is effective on a retrospective basis for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The adoption of this guidance did not have a material impact on our consolidated financial statements.

KAISER VENTURES LLC AND SUBSIDIARIES

In May 2011, the FASB issued additional guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The updated guidance is effective on a prospective basis for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The adoption of this guidance did not have a material impact on our consolidated financial statements.

PART II

As discussed in our Annual Report on Form 10-K for 2011 and in our reports on Form 10-Q for the first and second quarter of this year, we are engaged in certain claims and litigation. As of the date of the filing of this Report on Form 10-Q, there have not been any material developments in the legal proceedings involving the Company from the date of the filing of our Report on Form 10-K for the period ended December 31, 2011, and as updated by our first quarter 2012 Report on Form 10-Q and as further updated in our second quarter 2012 Report on Form 10-Q except as noted below:

ECEC Litigation Dismissed. On March 14, 2012, Eagle Crest Energy Company (“ECEC”) filed a declaratory relief action in the Bankruptcy Court against MRC, KEM and Kaiser LLC. ECEC is seeking to permit a proposed hydro-electric pumped storage project at the Eagle Mountain Site. The lawsuit sought declaratory relief only and no damages. In summary, the suit sought a declaration from the Bankruptcy Court stating that ECEC’s right of eminent domain (with ECEC assuming it would have such a right) and the process of seeking a license from FERC is not impacted by MRC’s bankruptcy. MRC, Kaiser LLC and KEM sought dismissal of such suit. The Bankruptcy Court agreed with MRC’s, Kaiser LLC’s and KEM’s positions in the matter and on August 29, 2012, the Bankruptcy Court dismissed ECEC’s lawsuit without prejudice.
