Report of Independent Registered Public Accounting Firm

To the Board of Directors of Rentech Nitrogen GP, LLC and Unitholders of Rentech Nitrogen Partners, L.P.

In our opinion, the accompanying consolidated balance sheets as of December 31, 2013 and 2012 and the related consolidated statements of income, of
comprehensive income, of stockholders equity (deficit) / partners capital and of cash flows for each of the two years in the period ended December 31, 2013, three months ended December 31, 2011 and fiscal year ended
September 30, 2011 present fairly, in all material respects, the financial position of Rentech Nitrogen Partners, L.P. and its subsidiaries at December 31, 2013 and 2012, and the results of their operations and their cash flows for each of
the two years in the period ended December 31, 2013, the three months ended December 31, 2011, and the fiscal year ended September 30, 2011 in conformity with accounting principles generally accepted in the United States of America.
Management and we previously concluded that the Partnership maintained effective internal control over financial reporting as of December 31, 2013. However, management has subsequently determined that material weaknesses in internal control
over financial reporting existed as of that date related to the Partnership not designing and maintaining effective controls over (i) the review of the cash flow forecasts used in the accounting for goodwill, (ii) the determination of the
goodwill impairment charge in accordance with generally accepted accounting principles, and (iii) maintaining documentation supporting managements review of events and changes in circumstances that indicate it is more likely than not that
a goodwill impairment has occurred between annual impairment tests existed as of that date. Accordingly, managements report has been restated and our present opinion on internal control over financial reporting, as presented herein, is
different from that expressed in our previous report. In our opinion, the Partnership did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2013 based on criteria established in
Internal Control  Integrated Framework (1992)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) because material weaknesses in internal control over financial reporting related to (i) the review
of the cash flow forecasts used in the accounting for goodwill, (ii) the determination of the goodwill impairment charge in accordance with generally accepted accounting principles, and (iii) maintaining documentation supporting
managements review of events and changes in circumstances that indicate it is more likely than not that a goodwill impairment has occurred between annual impairment tests existed as of that date. A material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.
The material weaknesses referred to above are described in Managements Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. We considered these material weaknesses in determining the nature, timing, and
extent of audit tests applied in our audit of the 2013 consolidated financial statements, and our opinion regarding the effectiveness of the Partnerships internal control over financial reporting does not affect our opinion on those
consolidated financial statements. The Partnerships management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control
over financial reporting included in Managements Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Partnerships internal
control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits
to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements
included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement
presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors
of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

Note 1  Description of Business

Description of Business

Rentech Nitrogen Partners, L.P. (RNP, the Partnership, we, us or our) owns and
operates two fertilizer facilities: our East Dubuque Facility and our Pasadena Facility. Our East Dubuque Facility is located in East Dubuque, Illinois, and has been in operation since 1965. We produce primarily ammonia and urea ammonium nitrate
solution (UAN) at our East Dubuque Facility, using natural gas as the facilitys primary feedstock. Our Pasadena Facility, which we acquired in November 2012, is located in Pasadena, Texas, and has been in operation producing
various products since the 1940s. In 2011, our Pasadena Facility was converted to the production of high-quality granulated synthetic ammonium sulfate, and began selling ammonium sulfate and ammonium thiosulfate as its primary products. We produce
ammonium sulfate, ammonium thiosulfate and sulfuric acid at our Pasadena Facility, using ammonia and sulfur as the facilitys primary feedstocks.

In fiscal year 2011, Rentech Energy Midwest Corporation (REMC or the Company), the predecessor of RNP, was a
wholly-owned subsidiary of Rentech, Inc. (Rentech). On November 9, 2011, the Partnership completed its initial public offering (the Offering) of 15,000,000 common units representing limited partner interests at a public
offering price of $20.00 per common unit. The common units sold to the public in the Offering represented 39.2% of the Partnership common units outstanding as of the closing of the Offering. Rentech Nitrogen Holdings, Inc. (RNHI),
Rentechs indirect wholly-owned subsidiary, owned the remaining 60.8% of the Partnership common units outstanding as of the closing of the Offering and Rentech Nitrogen GP, LLC (the General Partner), RNHIs wholly-owned
subsidiary, owns 100% of the non-economic general partner interest in us. The Partnerships assets consisted as of the closing of the Offering of all of the equity interests of REMC, which owned the East Dubuque Facility. At the Offering,
REMC was converted into a limited liability company, Rentech Nitrogen, LLC (RNLLC).

On November 1, 2012, the Partnership
completed its acquisition of 100% of the membership interests of Agrifos LLC (Agrifos) from Agrifos Holdings Inc. (the Seller), pursuant to a Membership Interest Purchase Agreement (the Purchase Agreement). Upon
the closing of this transaction (the Agrifos Acquisition), Agrifos became a wholly-owned subsidiary of the Partnership and its name changed to Rentech Nitrogen Pasadena Holdings, LLC. Rentech Nitrogen Pasadena Holdings, LLC owns all of
the member interests in Rentech Nitrogen Pasadena, LLC (RNPLLC), formerly known as Agrifos Fertilizer, LLC, which owns and operates the Pasadena Facility. For information on the Agrifos Acquisition refer to Note 3  Agrifos
Acquisition.

Change in Fiscal Year End and Basis of Presentation

On February 1, 2012, the Partnership changed its fiscal year end from September 30 to December 31. References to any of the
Partnerships calendar years mean the twelve-month period ended December 31 of that calendar year. References to our fiscal year means the fiscal year ended September 30, 2011. The statement of income for the calendar year ended
December 31, 2011 was derived by deducting the statement of income for the three months ended December 31, 2010 from the statement of income for the fiscal year ended September 30, 2011 and then adding the statement of income for the
three months ended December 31, 2011. The statements of income for calendar year ended December 31, 2011 and the three months ended December 31, 2010, while not required, are presented for comparison purposes. Financial information in
these notes with respect to calendar year 2011 and the three months ended December 31, 2010 is unaudited.

Note 2  Summary of Certain Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Partnership and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

Presentation

Prior to the closing of the Offering, REMC was consolidated with Rentechs operations following its acquisition by Rentech in 2006. During
that time REMC benefitted from certain corporate services provided by Rentech. These consolidated financial statements reflect REMC on a stand-alone or carve-out basis from Rentech for the period prior to the Offering and certain
corporate overhead costs were allocated to REMC and certain transactions between the Company and Rentech were re-categorized as if REMC were a standalone entity. Management believes that the method used to allocate the corporate overhead costs is
reasonable and reflects managements estimate of what the expenses would have been on a stand-alone basis for REMC.

Notes to Consolidated Financial Statements  Continued



Intercompany loans and advances from REMC to Rentech were recorded in a contra-equity account
receivable from parent company. No interest was recorded on this receivable. Amortization of the discount on REMCs term loan, which was recorded by Rentech, was pushed down to REMC. An estimate of the cost of time spent on REMCs matters
by Rentech human resources, legal, information systems, accounting and finance, investor relations and other Rentech personnel has been reflected in REMCs statements of income. A percentage of third party costs relating to the information
technology operating system was pushed down to REMC. Actual audit and tax services expenses for REMC were pushed down to REMC. Rentech over the years granted Restricted Stock Units and stock options to employees of REMC. The related stock based
compensation for such grants was recorded by Rentech. These costs have also been recorded by REMC in these consolidated financial statements. Total operating expenses allocated to REMC were $2.0 million for the fiscal year ended September 30,
2011. The entries relating to income taxes were determined on a separate return basis.

Subsequent Events

The Partnership has evaluated events occurring between December 31, 2013 and the date of these consolidated financial statements to ensure
that such events are properly reflected in these statements.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of
America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported
amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

East Dubuque and Pasadena Policy

Revenues are recognized when customers take ownership upon shipment from the East Dubuque Facility, Pasadena Facility, East Dubuque
Facilitys leased facility or Pasadena Facilitys distributors facilities and (i) assumes risk of loss, (ii) there are no uncertainties regarding customer acceptance, (iii) collection of the related receivable is
probable, (iv) persuasive evidence of a sale arrangement exists and (v) the sales price is fixed or determinable. Management assesses the business environment, the customers financial condition, historical collection experience,
accounts receivable aging and customer disputes to determine whether collectability is reasonably assured. If collectability is not considered reasonably assured at the time of sale, the Partnership does not recognize revenue until collection
occurs.

Natural gas, though not purchased for the purpose of resale, is occasionally sold by the East Dubuque Facility when contracted
quantities received are in excess of production and storage capacities, in which case the sales price is recorded in revenues and the related cost is recorded in cost of sales. Natural gas sales were approximately $3.4 million, $1.1 million and $0.1
million for 2013, 2012 and 2011, respectively.

East Dubuque Contracts

On April 26, 2006, Rentechs subsidiary, Rentech Development Corporation (RDC), entered into a Distribution Agreement
(the Distribution Agreement) with Royster-Clark Resources, LLC, who subsequently assigned the agreement to Agrium U.S.A., Inc. (Agrium), and RDC similarly assigned the agreement to REMC, prior to its conversion into RNLLC.
The Distribution Agreement is for a 10 year period, subject to renewal options. Pursuant to the Distribution Agreement, Agrium is obligated to use commercially reasonable efforts to promote the sale of, and solicit and secure orders from its
customers for nitrogen fertilizer products manufactured at the East Dubuque Facility, and to purchase from RNLLC nitrogen fertilizer products manufactured at the facility for prices to be negotiated in good faith from time to time. Under the
Distribution Agreement, Agrium is appointed as the exclusive distributor for the sale, purchase and resale of nitrogen products manufactured at the East Dubuque Facility. Sale terms are negotiated and approved by RNLLC. Agrium bears the credit risk
on products sold through Agrium pursuant to the Distribution Agreement. If an agreement is not reached on the terms and conditions of any proposed Agrium sale transaction, RNLLC has the right to sell to third parties provided the sale is on the same
timetable and volumes and at a price not lower than the one proposed by Agrium. For the calendar years ended December 31, 2013 and 2012, the three months ended December 31, 2011 and the fiscal year ended September 30, 2011, the
Distribution Agreement accounted for 79%, 83%, 92% and 83%, respectively, of net revenues from product sales for the East Dubuque Facility. Receivables from Agrium accounted for 84% and 73% of the total accounts receivable balance of the East
Dubuque Facility as of December 31, 2013 and 2012, respectively. RNP negotiates sales with other customers and these transactions are not subject to the terms of the Distribution Agreement.

Under the Distribution Agreement, the East Dubuque Facility pays commissions to Agrium not to
exceed $5 million during each contract year on applicable gross sales during the first 10 years of the agreement. The commission rate was 2% during the first year of the agreement and increased by 1% on each anniversary date of the agreement up to
the current maximum rate of 5%. For the calendar years ended December 31, 2013 and 2012, the three months ended December 31, 2011 and the fiscal year ended September 30, 2011, the effective commission rate associated with sales under
the Distribution Agreement was 3.6%, 2.7%, 2.6% and 4.3%, respectively. The commission expense was recorded in cost of sales for all periods.

Pasadena Contracts

We sell substantially all of our Pasadena Facilitys products through marketing and distribution agreements. Pursuant to an exclusive
marketing agreement we have entered into with Interoceanic Corporation (IOC), IOC has the exclusive right and obligation to market and sell all of our Pasadena Facilitys ammonium sulfate product. Under the marketing agreement, IOC
is required to use commercially reasonable efforts to market the product to obtain the most advantageous price. We compensate IOC for transportation and storage costs relating to the ammonium sulfate product it markets through the pricing structure
under the marketing agreement. The marketing agreement has a term that ends December 31, 2016, but automatically renews for subsequent one-year periods (unless either party delivers a termination notice to the other party at least 210 days
prior to an automatic renewal). The marketing agreement may be terminated prior to its stated term for specified causes. During the calendar year ended December 31, 2013 and the period beginning November 1, 2012 through December 31,
2012, the marketing agreement with IOC accounted for 100% of our Pasadena Facilitys revenues from the sale of ammonium sulfate. In addition, we have an arrangement with IOC that permits us to store 59,500 tons of ammonium sulfate at
IOC-controlled terminals, which are located near end customers of our Pasadena Facilitys ammonium sulfate. This arrangement currently is not governed by a written contract. We also have marketing and distribution agreements to sell other
products that automatically renew for successive one year periods.

Deferred Revenue

A significant portion of the revenue recognized during any period may be related to product prepayment contracts or products stored at IOC
facilities, for which cash was collected during an earlier period, with the result that a significant portion of revenue recognized during a period may not generate cash receipts during that period. As of December 31, 2013 and 2012, deferred
revenue was approximately $20.4 million and $29.7 million, respectively. At the East Dubuque Facility, we record a liability for deferred revenue to the extent that payment has been received under product prepayment contracts, which create
obligations for delivery of product within a specified period of time in the future. The terms of these product prepayment contracts require payment in advance of delivery. At the Pasadena Facility, IOC pre-pays a portion of the sales price for
shipments received into its storage facilities. The Partnership recognizes revenue related to the product prepayment contracts or products stored at IOC facilities and relieves the liability for deferred revenue when products are shipped (including
shipments to end customers from IOC facilities).

Cost of Sales

Cost of sales are comprised of manufacturing costs related to the Partnerships fertilizer products and processing costs for services.
Cost of sales expenses include direct materials (such as natural gas, ammonia, sulfur and sulfur acid), direct labor, indirect labor, employee fringe benefits, depreciation on plant machinery, electricity and other costs, including shipping and
handling charges incurred to transport products sold.

The Partnership enters into short-term contracts to purchase physical supplies of
natural gas in fixed quantities at both fixed and indexed prices. The Partnership anticipates that it will physically receive the contract quantities and use them in the production of fertilizer. The Partnership believes it is probable that the
counterparties will fulfill their contractual obligations when executing these contracts. Natural gas purchases, including the cost of transportation to the East Dubuque Facility, are recorded at the point of delivery into the pipeline system.

Accounting for Derivative Instruments

Accounting guidance establishes accounting and reporting requirements for derivative instruments and hedging activities. This guidance requires
recognition of all derivative instruments as assets or liabilities on the Partnerships balance sheet and measurement of those instruments at fair value. The accounting treatment of changes in fair value is dependent upon whether or not a
derivative instrument is designated as a hedge and if so, the type of hedge. The Partnership currently does not designate any of its derivatives as hedges for financial accounting purposes. Gains and losses on derivative instruments not designated
as hedges are currently included in earnings and reported under cash from operating activities.

Notes to Consolidated Financial Statements  Continued



We elect the normal purchase normal sale exemption for our commodity-based derivative
instruments. As such, we do not recognize the unrealized gains or losses related to these derivative instruments in our consolidated financial statements. For interest rate swaps, the Partnership did not use hedge accounting; however, the
Partnership reflected the instruments at fair value and any change in value was recorded in other expense, net on the consolidated statement of income. The Partnership terminated the interest rate swaps in calendar year 2013.

Cash

The Partnership has checking
and savings accounts with major financial institutions. At times balances with these financial institutions may be in excess of federally insured limits.

Accounts and Other Receivables

Trade receivables are recorded at net realizable value. The allowance for doubtful accounts reflects the Partnerships best estimate of
probable losses inherent in the accounts receivable balance. The Partnership determines the allowance based on known troubled accounts, historical experience, and other currently available evidence. The Partnership reviews its allowance for doubtful
accounts quarterly. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the
potential for recovery is considered remote.

At December 31, 2013, the Partnership has recorded an insurance receivable of
approximately $1.7 million for losses incurred at a November 2013 fire at the East Dubuque Facility. The receivable is not in dispute, and recovery is probable due to a legally enforceable insurance policy.

Inventories

Inventories consist
of raw materials and finished goods. The primary raw material used by the East Dubuque Facility in the production of its nitrogen products is natural gas. The primary raw materials used by the Pasadena Facility in the production of its products are
ammonia and sulfur. Raw materials also include certain chemicals used in the manufacturing process. Finished goods include the products stored at each plant that are ready for shipment along with any inventory that may be stored at remote
facilities. The Partnership allocates fixed production overhead costs to inventory based on the normal capacity of its production facilities and unallocated overhead costs are recognized as expense in the period incurred. At December 31, 2013
and 2012, inventories on the balance sheets included depreciation of approximately $1.2 million and $1.0 million, respectively.

Inventories are stated at the lower of cost or estimated net realizable value. The cost of inventories is determined using the first-in
first-out method. The estimated net realizable value is based on customer orders, market trends and historical pricing. On at least a quarterly basis, the Partnership performs an analysis of its inventory balances to determine if the carrying amount
of inventories exceeds its net realizable value. If the carrying amount exceeds the estimated net realizable value, the carrying amount is reduced to the estimated net realizable value.

Property, Plant and Equipment

Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation expense is calculated using the straight-line
method over the estimated useful lives of the assets, except for platinum catalyst, as follows:

Expenditures during turnarounds or at other times for improving, replacing or adding to
RNPs assets are capitalized. Expenditures for the acquisition, construction or development of new assets to maintain RNPs operating capacity, or to comply with environmental, health, safety or other regulations, are also capitalized.
Costs of general maintenance and repairs are expensed.

When property, plant and equipment is retired or otherwise disposed of, the asset
and accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected in operating expenses.

Spare parts
are maintained by each facility to reduce the length of possible interruptions in plant operations from an infrastructure breakdown at the facility. The spare parts may be held for use for years before the spare parts are used. As a result, they are
capitalized as a fixed asset at cost. When spare parts are utilized, the book values of the assets are charged to earnings as a cost of production. Periodically, the spare parts are evaluated for obsolescence and impairment and if the value of the
spare parts is impaired, it is charged against earnings.

Long-lived assets and construction in progress are reviewed whenever events or
changes in circumstances indicate that the carrying amount may not be recoverable. If the expected future cash flow from the use of the asset and its eventual disposition is less than the carrying amount of the asset, an impairment loss is
recognized and measured using the assets fair value.

The Partnership capitalizes certain direct development costs associated with
internal-use software, including external direct costs of material and services, and payroll costs for employees devoting time to software implementation projects. Costs incurred during the preliminary project stage, as well as maintenance and
training costs, are expensed as incurred.

The Partnership has recorded asset retirement obligations (AROs) related to future
costs associated with (i) the removal of contaminated material at the former phosphorous plant at the Pasadena Facility and handling (ii) disposal of asbestos at the East Dubuque Facility. The fair value of a liability for an ARO is
recorded in the period in which it is incurred and the cost of such liability increases the carrying amount of the related long-lived asset by the same amount. The liability is accreted each period through charges to operating expense and the
capitalized cost is depreciated over the remaining useful life of the asset. The liability at December 31, 2013 and 2012 was approximately $2.8 million and $3.1 million.

Construction in Progress

We also
capitalize costs for improvements to the existing machinery and equipment at our facilities and certain costs associated with our information technology initiatives. We do not depreciate construction in progress costs until the underlying assets are
placed into service.

Acquisition Method of Accounting

The Partnership accounts for business combinations using the acquisition method of accounting, which requires, among other things, that assets
acquired, liabilities assumed and earn-out consideration be recognized at their fair values as of the acquisition date. The Partnership has recognized goodwill and intangibles related to its acquisition as described in Note 3  Agrifos
Acquisition. The earn-out consideration will be measured at each reporting date with changes in its fair value recognized in the consolidated statements of income.

Goodwill

Goodwill represents the
excess of the purchase price over the fair value of identifiable net assets acquired in a business acquisition. The Partnership tests goodwill assets for impairment annually, or more often if an event or circumstance indicates that impairment may
have occurred. The analysis of the potential impairment of goodwill is a two step process. Step one of the impairment test consists of comparing the fair value of the reporting unit with the aggregate carrying value, including goodwill. If the
carrying value of a reporting unit exceeds the reporting units fair value, step two must be performed to determine the amount, if any, of the goodwill impairment. Step one of the goodwill impairment test involves a high degree of judgment and
consists of a comparison of the fair value of a reporting unit with its book value. The fair value of the Pasadena reporting unit is based upon various assumptions and is based on the discounted cash flows that the business can be expected to
generate in the future (the Income Approach). The Income Approach valuation method requires the Company to make projections of revenue and operating costs over a multi-year period. Additionally, the Partnership made an estimate of a
weighted average cost of capital that a market participant would use as a discount rate.

If the fair value of the reporting unit is less than its carrying value, step two of the
impairment test is performed. Step two of the goodwill impairment test consists of comparing the implied fair value of the reporting units goodwill against the carrying value of the goodwill. Determining the implied fair value of goodwill
requires the valuation of a reporting units identifiable tangible and intangible assets and liabilities as if the reporting unit had been acquired in a business combination on the testing date. The valuation of assets and liabilities in step
two is performed only for purposes of assessing goodwill for impairment. See Note 7  Goodwill.

Intangible Assets

Intangible assets arose in conjunction with the Agrifos Acquisition (See Note 3  Agrifos Acquisition) and consist of technology to
produce ammonium sulfate and the Pasadena Facilitys marketing agreement with IOC.

Intangible assets consist of the following at
December 31, 2013 and 2012 (amounts in thousands):



|                                    |  |      |        |   |      |   |        |              |  |  |     |

The amortization of the assets will result in amortization expense of approximately $1.2 million for each of
the next five years.

Income Taxes

We are not a taxable entity for federal income tax purposes. As such, we do not directly pay federal income tax. Our taxable income or loss,
which may vary substantially from the net income or net loss we report in our consolidated statement of income, is includable in the federal income tax returns of each partner. The aggregate difference in the basis of our net assets for financial
and tax reporting purposes cannot be readily determined as we do not have access to information about each partners tax attributes in us.

Net
Income Per Common Unit

The Partnerships net income is allocated wholly to the common unitholders since the General Partner
has a non-economic interest. The net income per common unit for the three months and year ended December 31, 2011 on the Consolidated Statement of Income are based on net income of the Partnership after the closing of the Offering on
November 9, 2011 through December 31, 2011, since this is the amount of net income that is attributable to the newly issued common units.

Basic income per common unit allocated to common unitholders is calculated by dividing net income allocated to common unitholders by the
weighted average number of common units outstanding for the period. Diluted net income per common unit allocated to common unitholders is calculated by dividing net income allocated to common unitholders by the weighted average number of common
units outstanding plus the dilutive effect, calculated using the treasury stock method for the unvested phantom units. Phantom units are settled for common units upon vesting and are issued in tandem with distribution rights during the
vesting period.

Comprehensive Income

Comprehensive income includes all changes in partners capital during the period from non-owner sources. To date, accumulated other
comprehensive income is comprised of adjustments to the defined benefit pension plans and the postretirement benefit plan.

Quarterly Distributions
of Available Cash

The Partnerships policy is to distribute all of the cash available for distribution which it generates
each quarter. Cash available for distribution for each quarter will be determined by the board of directors of the General Partner following the end of each quarter. The Partnership expects that cash available for distribution for each quarter will
generally be calculated as the cash it generates during the quarter, less cash needed for maintenance capital expenditures not funded by capital proceeds, debt service and other contractual

obligations, and reserves for future operating or capital needs that the board of directors of the General Partner deems necessary or appropriate. The Partnership does not intend to maintain
excess distribution coverage for the purpose of maintaining stability or growth in its quarterly distribution or otherwise to reserve cash for distributions, nor does it intend to incur debt to pay quarterly distributions. The Partnership has no
legal obligation to pay distributions. Distributions are not required by the Partnerships partnership agreement and the Partnerships distribution policy is subject to change at any time at the discretion of the board of directors of the
General Partner. Any distributions made by the Partnership to its unitholders will be done on a pro rata basis.

Related Parties

On November 9, 2011, the closing date of the Offering, the Partnership, the General Partner and Rentech entered into a services agreement,
pursuant to which the Partnership and the General Partner will obtain certain management and other services from Rentech. The Partnerships consolidated financial statements following the Offering reflect the impact of the reimbursements the
Partnership is required to make to Rentech under the services agreement instead of those used for purposes of preparing REMCs stand-alone financial statements. Under the services agreement, the Partnership, its subsidiaries and the General
Partner are obligated to reimburse Rentech for (i) all costs, excluding share-based compensation, incurred by Rentech or its affiliates in connection with the employment of its employees who are seconded to the Partnership and who provide the
Partnership services under the agreement on a full-time basis; (ii) a prorated share of costs, excluding share-based compensation, incurred by Rentech or its affiliates in connection with the employment of its employees, excluding seconded
personnel, who provide the Partnership services under the agreement on a part-time basis, with such prorated share determined by Rentech on a commercially reasonable basis, based on the estimated percent of total working time that such personnel are
engaged in performing services for the Partnership; (iii) a prorated share of certain administrative costs, in accordance with the agreement, including office costs, services by outside vendors, other general and administrative costs; and
(iv) any taxes (other than income taxes, gross receipt taxes and similar taxes) incurred by Rentech or its affiliates for the services provided under the agreement. During the calendar years ended December 31, 2013 and 2012, Rentech, in
accordance with the services agreement, billed the Partnership approximately $18.6 million and $14.1 million, respectively.

Recent Accounting
Pronouncements

In January 2013, the Financial Accounting Standards Board (the FASB) issued guidance that requires a
company to disclose information about financial instruments that have been offset on the balance sheet or subject to an enforceable master netting agreement, irrespective of whether they have been offset, and related arrangements to enable users of
a companys financial statements to understand the effect of those arrangements on the companys financial position. Companies will be required to provide both net (offset amounts) and gross information in the notes to the financial
statements for relevant assets and liabilities that are offset. This guidance is effective for interim and annual periods beginning on or after January 1, 2013 and requires retrospective application, and thus became effective for the
Partnerships interim period beginning on January 1, 2013. The adoption of this guidance did not have any impact on the Partnerships consolidated financial position, results of operations or disclosures.

In February 2013, the FASB issued guidance requiring companies to disclose information about amounts reclassified out of accumulated other
comprehensive income and their corresponding effect on net income. This guidance is effective for interim and annual periods beginning after December 15, 2012, and thus became effective for the Partnerships interim period beginning on
January 1, 2013. The adoption of this guidance did not have a material impact on the Partnerships consolidated financial position, results of operations or disclosures.

Note 3  Agrifos Acquisition

On November 1, 2012, the Company acquired all of the membership interest of Agrifos. The purchase price for Agrifos and
its subsidiaries consisted of an initial purchase price of $136.3 million in cash, less working capital adjustments, and $20.0 million in common units representing limited partnership interests in the Partnership (the Common Units),
which reduced Rentechs ownership interest in the Partnership at the time from 60.8% to 59.9%, as well as potential earn-out consideration of up to $50.0 million to be paid in Common Units or cash at the Partnerships option based on the
amount by which the two-year Adjusted EBITDA, as defined in the Purchase Agreement, of the Pasadena Facility exceeds certain thresholds. Among other terms, the Seller is required to indemnify us for a period of six years after the closing for
certain environmental matters relating to the Pasadena Facility, which indemnification obligations are subject to important limitations including a deductible and an overall cap. We deposited with an escrow agent in several escrow accounts a portion
of the initial consideration consisting of an aggregate of $7.25 million in cash, and 323,276 Common Units, representing a value of $12.0 million, which amounts may be used to satisfy certain indemnity claims upon the occurrence of certain events.
Any earn-out consideration would be paid after April 30, 2015 and the completion of the relevant calculations in either common units or cash at our option.

the Purchase Agreement, as defined in Note 4  Fair Value. The earn-out consideration will be measured at each reporting date with changes in its fair value recognized in the consolidated statements of operations. As of December 31,
2013, the fair value of the potential earn-out consideration was $0.

During the calendar year ended December 31, 2013, the Partnership and the Seller finalized the working
capital adjustments which resulted in an increase in the preliminary purchase price of approximately $0.3 million. The working capital adjustments receivable was recorded separately from the purchase price allocation shown above. The finalization
and recording of the cash receipt resulted in cash increasing by approximately $2.2 million and other receivables decreasing by approximately $2.5 million. During the calendar year ended December 31, 2013, the Partnership recognized adjustments
to the preliminary purchase price allocation with an increase in fair value to goodwill of approximately $0.6 million and accrued liabilities of approximately $0.3 million.

The operations of Agrifos are included in the consolidated statement of income effective November 1, 2012. During the calendar year ended
December 31, 2012, the Partnership recorded revenue and net loss related to Agrifos of approximately $37.4 million and $2.6 million, respectively. Acquisition related costs for this acquisition totaled approximately $4.1 million for the
calendar year ended December 31, 2012 and have been included in the consolidated statements of income within selling, general and administrative expense.

Note 4  Fair Value

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between
market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or
liabilities. These inputs can be readily observable, market corroborated or generally unobservable inputs. The Partnership makes certain assumptions it believes that market participants would use in pricing assets or liabilities, including
assumptions about risk, and the risks inherent in the inputs to valuation techniques. Credit risk of the Partnership and its counterparties is incorporated in the valuation of assets and liabilities. The Partnership believes it uses valuation
techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

A fair value hierarchy
has been established that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or
liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be classified
in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability, and
may affect the valuation of the asset or liability and its placement within the fair value hierarchy. The Partnership classifies fair value balances based on the fair value hierarchy, defined as follows:

Level 1 Consists of unadjusted quoted prices in active markets for identical assets or liabilities that the Partnership has the ability to access as of the reporting date.

Level 2 Consists of inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data.

Level 3 Consists of unobservable inputs for assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any,
market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost-benefit constraints.

Fair values of cash, deposits, other current assets, accounts payable, accrued liabilities and other current liabilities are assumed to
approximate carrying value since they are short term and can be settled on demand.

The following table presents the financial instruments
that require fair value disclosure as of December 31, 2013.

Notes

The Notes, as defined in Note 8  Debt, are deemed to be Level 1 financial instruments because there was an active market for such
debt. The fair value of such debt had been determined based on market prices.

Credit Facilities and Term Loan

The credit facilities and term loan were deemed to be Level 2 financial instruments because the measurement was based on observable market
data. The Partnership used part of the proceeds from the offering of the Notes to repay in full and terminate the Second 2012 Credit Agreement, as defined in Note 8  Debt, and related interest rate swaps.

Interest Rate Swaps

In 2012,
RNLLC entered into two forward starting interest rate swaps in notional amounts which covered a portion of its outstanding borrowings. The interest rate swaps were deemed to be Level 2 financial instruments because the measurements were based on
observable market data. The Partnership used a standard swap contract valuation method to value its interest rate derivatives, and the inputs it used for present value discounting included forward one-month and three-month LIBOR rates, risk-free
interest rates and an estimate of credit risk. The change in fair value was recorded in other expense, net on the consolidated statement of income. The realized loss represents the cash payments required under the interest rate swaps.

Net gain (loss) on interest rate swaps:

|                                      |  |                                          |     |   |      |   |      |  
|Total net loss on interest rate swaps |  | $                                        | (7  | ) |      | $ | (951 | )
|                                      |  |                                          |     |   |      |   |      |  

During the calendar year ended December 31, 2013, the Partnership paid approximately $0.9 million to
terminate the interest rate swaps as described above.

Earn-out Consideration

The earn-out consideration relates to potential additional consideration the Partnership may be required to pay under the Purchase Agreement
relating to the Agrifos Acquisition. The earn-out consideration is deemed to be a Level 3 financial instrument because the measurement is based on unobservable inputs. The fair value of earn-out consideration was determined based on the
Partnerships analysis of various scenarios involving the achievement of certain levels of Adjusted EBITDA, as defined in the Purchase Agreement, over a two year period. The scenarios, which included a weighted probability factor, involved
assumptions relating to the market prices of the Partnerships products and feedstocks, as well as product profitability and production. The earn-out consideration will be measured at each reporting date with changes in its fair value
recognized in the consolidated statements of income. For the calendar year ended December 31, 2013, the fair value of the liability decreased by approximately $4.9 million. At December 31, 2013, the fair value of the potential earn-out
consideration relating to the Agrifos Acquisition was $0. The decrease in fair value was a result of lower than expected profitability in 2013 due primarily to unfavorable weather and increased Chinese exports, as well as a reduced outlook for
longer-term profitability due to reduced levels of nitrogen fertilizer prices. Due to an unusually wet spring, there was a shortened planting season which resulted in lower ammonium sulfate revenues during the calendar year ended December 31,
2013. In addition, significant volumes of urea were exported from China and this supply suppressed global urea and other nitrogen fertilizer prices.

The goodwill resulting from the Agrifos Acquisition is deductible for tax purposes.

The inventory impairment (see Note 5  Inventories), negative gross margin and EBITDA in the calendar year ended December 31, 2013
and revised cash flow projections developed during the calendar year ended December 31, 2013 indicated that an impairment of the goodwill related to the Pasadena Facility was probable.

Ammonium sulfate is the primary product of the Pasadena Facility. Results for the calendar year ended December 31, 2013 and our
projections of future cash flow from the production and sale of this product are worse than the results originally projected in late 2012, when the Partnership acquired Agrifos. The expected results and cash flows as of 2012 were utilized to
allocate the purchase price of the Agrifos Acquisition, as described in Note 3  Agrifos Acquisition. The primary cause of the reduction in the estimated fair value of the Pasadena reporting unit is the decline in the cash flow expected to be
generated from the sale of ammonium sulfate, compared to the expectations at the time of the acquisition. A major cause of the lower expected cash flows is a decline in the level of prices, and expected prices, for nitrogen fertilizer caused by,
among other things, lower corn prices, poor weather conditions for fertilizer application throughout the United States in 2013 and increased supply of urea from China.

Factors that affect cash flows include, but are not limited to, product prices; product transportation costs; product sales volumes; feedstock
prices and availability; labor, maintenance, and other operating costs; required capital expenditures, and plant productivity. The Pasadena Facility generated negative EBITDA during the calendar year ended December 31, 2013. EBITDA is currently
expected to be positive in 2014, but the current projection is well below the projection at the time of the acquisition, and is based on current and projected levels of prices for the products of, and inputs for, the Pasadena Facility. Current and
projected prices for the products and inputs are below the levels at the time of the acquisition, yielding expectations for lower variable dollar margins per ton of product, even though percentage margins are expected to be consistent with those at
the time of the acquisition because the prices of ammonium sulfate and its major raw materials have dropped by similar percentages. Lower dollar variable margins provide fewer dollars per ton sold to cover the fixed costs of the facility, resulting
in reduced expectations of cash generated by the facility in a lower-price environment. In addition, the Pasadena Facilitys production has been lower than expected due to plant outages, and costs have been higher than expected due to higher
maintenance expense.

Based upon its analysis of the value of the Pasadena reporting unit using the Income Approach, the Partnership
recorded an estimated impairment to goodwill of $30.0 million during the quarter ended September 30, 2013. During the fourth quarter the Partnership performed a step 2 analysis of goodwill and determined no adjustment to the initial
goodwill impairment charge was necessary. There are significant assumptions involved in determining a goodwill impairment charge, which includes discount rates, terminal growth rates, future prices of end products and raw materials, terminal values
and production volumes. The various valuation methods used (income approach, replacement cost, market approach) are also weighted in determining fair market value. Changes to any of these assumptions could increase or decrease the fair value of the
Pasadena reporting unit. At December 31, 2013 the fair value of the Pasadena reporting unit is essentially equal to its carrying value and any adverse change to the critical assumptions used to measure discounted cash flows could result in a
diminution in fair value that may result in additional goodwill impairment charges. If gross margins on sales of products were to decline 5 percent from our expectations, an impairment charge of approximately $15.0 million would be required at
December 31, 2013. If the discount rate were to increase by 100 basis points from our expectations, an impairment charge of approximately $16.5 million would be required at December 31, 2013.

Note 8  Debt

The
Partnerships debt obligations at December 31, 2013 consist of $320.0 million of Notes, as defined below. The Partnerships debt obligations at December 31, 2012 consisted of approximately $193.3 million in outstanding advances
under its Second 2012 Credit Agreement, as defined below. Debt premium, discount and issuance expenses incurred in connection with financing are deferred and amortized on a straight line basis.

First and Second 2012 Credit Agreements

On February 28, 2012, RNLLC entered into a credit agreement (the First 2012 Credit Agreement). The First 2012 Credit Agreement
consisted of (i) a $100.0 million multiple draw term loan, and (ii) a $35.0 million revolving facility.

On October 31,
2012, RNLLC, the Partnership, RNPLLC and certain subsidiaries of RNPLLC entered into a new credit agreement (the Second 2012 Credit Agreement). The Second 2012 Credit Agreement amended, restated and replaced the First 2012 Credit
Agreement. The Second 2012 Credit Agreement consisted of (i) a $110.0 million multiple draw term loan (the CapEx Facility) to be used by the Partnership and its subsidiaries for expansion projects and general partnership purposes,
(ii) a $155.0 million term loan to fund the Agrifos Acquisition and (iii) the $35.0 million revolving credit facility (the 2012 Revolving Credit Facility).

Notes to Consolidated Financial Statements  Continued



The Second 2012 Credit Agreement had a maturity date of October 31, 2017. Borrowings
under the Second 2012 Credit Agreement bore interest at a rate equal to an applicable margin plus, at RNLLCs option, either (a) in the case of base rate borrowings, a rate equal to the highest of (1) the prime rate, (2) the
federal funds rate plus 0.5% or (3) LIBOR for an interest period of three months plus 1.00% or (b) in the case of LIBOR borrowings, the offered rate per annum for deposits of dollars for the applicable interest period on the day that was
two business days prior to the first day of such interest period. The applicable margin for borrowings under the Second 2012 Credit Agreement was 2.75% with respect to base rate borrowings and 3.75% with respect to LIBOR borrowings. Additionally,
RNLLC were required to pay a fee to the lenders under the CapEx Facility on the undrawn available portion at a rate of 0.75% per annum and a fee to the lenders under the 2012 Revolving Credit Facility on the undrawn available portion at a rate
of 0.50% per annum. RNLLC also was required to pay customary letter of credit fees on issued letters of credit.

Notes Offering

On April 12, 2013, the Partnership and Rentech Nitrogen Finance Corporation, a wholly-owned subsidiary of the Partnership (Finance
Corporation and collectively with the Partnership, the Issuers), issued $320.0 million of 6.5% second lien senior secured notes due 2021 (the Notes) to qualified institutional buyers and non-United States persons in a
private offering exempt from the registration requirements of the Securities Act of 1933, as amended. The Notes bear interest at a rate of 6.5% per year, payable semi-annually in arrears with the first interest payment made on October 15,
2013. The Notes will mature on April 15, 2021, unless repurchased or redeemed earlier in accordance with their terms. The Partnership used part of the net proceeds from the offering to repay in full and terminate the Second 2012 Credit
Agreement and related interest rate swaps, and intends to use the remaining proceeds to pay for expenditures related to its expansion projects and for general partnership purposes.

The Notes are fully and unconditionally guaranteed, jointly and severally, by each of the Partnerships existing domestic subsidiaries,
other than Finance Corporation. In addition, the Notes and the guarantees thereof are collateralized by a second priority lien on substantially all of the Partnerships and the guarantors assets, subject to permitted liens.

The Issuers may redeem some or all of the Notes at any time prior to April 15, 2016 at a redemption price equal to 100% of the principal
amount of the Notes redeemed, plus a make whole premium, and accrued and unpaid interest, if any, to the date of redemption. At any time prior to April 15, 2016, the Partnership may also, on any one or more occasions, redeem up to
35% of the aggregate principal amount of the Notes issued with the net proceeds of certain equity offerings at 106.5% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to the date of redemption. On or after
April 15, 2016, the Partnership may redeem some or all of the Notes at a premium that will decrease over time, plus accrued and unpaid interest, if any, to the redemption date.

2013 Credit Agreement

On
April 12, 2013, the Partnership and Finance Corporation (collectively the Borrowers) entered into a new credit agreement (the 2013 Credit Agreement). The 2013 Credit Agreement consists of a $35.0 million senior secured
revolving credit facility (the Credit Facility). The Borrowers may use the 2013 Credit Agreement to fund their working capital needs, to fund capital expenditures, to issue letters of credit and for other general partnership purposes.
The 2013 Credit Agreement also includes a $10.0 million letter of credit sublimit. The commitment under the Credit Facility may be increased by up to $15.0 million upon the Borrowers request at the discretion of the lenders and subject to
certain customary requirements. As of December 31, 2013, borrowings under the Credit Facility were strictly limited if the Partnership exceeded a Secured Leverage Ratio of 3.75 to 1.00. As of December 31, 2013, the Partnerships
Secured Leverage Ratio was 4.71 to 1.00, and on such date there were no outstanding advances under the Credit Facility.

Borrowings under
the 2013 Credit Agreement bear interest at a rate equal to an applicable margin plus, at the Borrowers option, either (a) in the case of base rate borrowings, a rate equal to the highest of (1) the prime rate, (2) the federal
funds rate plus 0.5% or (3) LIBOR for an interest period of three months plus 1.00% or (b) in the case of LIBOR borrowings, the offered rate per annum for deposits of dollars for the applicable interest period on the day that is two
business days prior to the first day of such interest period. If the Borrowers maintain a secured leverage ratio of less than 1.75:1.00 for the last quarter reported to the lenders, then the applicable margin for borrowings under the 2013 Credit
Agreement is 2.25% with respect to base rate borrowings and 3.25% with respect to LIBOR borrowings. If the Borrowers maintain a secured leverage ratio equal or greater than 1.75:1.00 for the last quarter reported to the lenders, then the applicable
margin for borrowings under the 2013 Credit Agreement is 2.50% with respect to base rate borrowings and 3.50% with respect to LIBOR borrowings.

Additionally, the Borrowers are required to pay a fee to the lenders under the 2013 Credit Agreement on the average undrawn available portion
of the Credit Facility at a rate equal to 0.50% per annum. The Borrowers must also pay a fee to the lenders under the 2013 Credit Agreement at a rate equal to the product of the average daily undrawn face amount of all letters of credit issued,
guaranteed or supported by risk participation agreements multiplied by a per annum rate equal to the applicable margin with respect to LIBOR borrowings, plus all customary letter of credit fees on issued letters of credit.

All of the Partnerships existing subsidiaries (other than Finance Corporation)
guarantee, and certain of the Partnerships future domestic subsidiaries will guarantee, the Partnerships obligations pursuant to the 2013 Credit Agreement. The 2013 Credit Agreement, any hedging agreements issued by lenders under the
2013 Credit Agreement and the subsidiary guarantees are collateralized by the same collateral securing the Notes, which includes substantially all of the Partnerships assets and all of the assets of its subsidiaries. After the occurrence and
during the continuation of an event of default, proceeds of any collection, sale, foreclosure or other realization upon any collateral will be applied to repay obligations under the 2013 Credit Agreement and the subsidiary guarantees thereof to the
extent secured by the collateral before any such proceeds are applied to repay obligations under the Notes, subject to a first lien cap (equal to the greater of $65 million or 20% of the Partnerships consolidated net tangible assets (as
defined in the Indenture governing the Notes), plus obligations in respect of the first-priority secured indebtedness and obligations under certain hedging agreements and cash management agreements).

The 2013 Credit Agreement will terminate on April 12, 2018. Any amounts still outstanding at that time will be immediately due and
payable. The Borrowers may voluntarily prepay their utilization and/or permanently cancel all or part of the available commitments under the 2013 Credit Agreement in a minimum amount of $5.0 million. Amounts repaid may be reborrowed. Borrowings
under the 2013 Credit Agreement will be subject to mandatory prepayment under certain circumstances, with customary exceptions, from the proceeds of permitted dispositions of assets and from certain insurance and condemnation proceeds.

As of December 31, 2013, the Partnership was in compliance with all covenants under the Notes and the 2013 Credit Agreement.

Debt consists of the following:

Notes to Consolidated Financial Statements  Continued



Note 9  Commitments and Contingencies

Natural Gas Forward Purchase Contracts

The Partnerships policy and practice are to enter into fixed-price forward purchase contracts for natural gas in conjunction with
contracted product sales in order to substantially fix gross margin on those product sales contracts. The Partnership may also enter into a limited amount of additional fixed-price forward purchase contracts for natural gas in order to minimize
monthly and seasonal gas price volatility. The Partnership occasionally enters into index-price contracts for the purchase of natural gas. The Partnership elects the normal purchase normal sale exemption for these derivative instruments. As such,
the Partnership does not recognize the unrealized gains or losses related to these derivative instruments in its consolidated financial statements. The Partnership has entered into multiple natural gas forward purchase contracts for various delivery
dates through March 31, 2014. Commitments for natural gas purchases consist of the following:

|                                                                                                     |  |                                              |       |  |      |   |       |

Subsequent to December 31, 2013 through February 28, 2014, the Partnership entered into additional
fixed-quantity forward purchase contracts at fixed and indexed prices for various delivery dates through March 31, 2014. The total MMBtus associated with these additional forward purchase contracts are approximately 0.5 million and the
total amount of the purchase commitments are approximately $4.5 million, resulting in a weighted average rate per MMBtu of approximately $9.27 in these new commitments. The Partnership is required to make additional prepayments under these forward
purchase contracts in the event that market prices fall below the purchase prices in the contracts.

Operating Leases

The Partnership has various operating leases of real and personal property which expire through March 2018. Total lease expense for the
calendar years ended December 31, 2013 and 2012, the three months ended December 31, 2011 and the fiscal year ended September 30, 2011 was $1.0 million, $1.1 million, $0.3 million and $0.8 million, respectively.

Future minimum lease payments as of December 31, 2013 are as follows (in thousands):

Litigation

The Partnership is party to litigation from time to time in the normal course of business. The Partnership accrues legal liabilities only when
it concludes that it is probable that it has an obligation for such costs and can reasonably estimate the amount of such costs. In cases where the Partnership determines that it is not probable, but reasonably possible that it has a material
obligation, it discloses such obligations and the possible loss or range of loss, if such estimate can be made. While the outcome of the Partnerships current matters are not estimable or probable, the Partnership maintains insurance to cover
certain actions and believes that resolution of its current litigation matters will not have a material adverse effect on the Partnership.

Regulation

The Partnerships
business is subject to extensive and frequently changing federal, state and local, environmental, health and safety regulations governing a wide range of matters, including the emission of air pollutants, the release of hazardous substances into the
environment, the treatment and discharge of waste water and the storage, handling, use and transportation of the Partnerships fertilizer products, raw materials, and other substances that are part of our operations. These laws include the
Clean Air Act (the CAA), the federal Water Pollution Control Act, the Resource Conservation and Recovery Act, the Comprehensive Environmental Response, Compensation and Liability Act, the Toxic Substances Control Act, and various other
federal, state and local laws and regulations. The laws and regulations to which the Partnership is subject are complex, change frequently and have tended to become more stringent over time. The ultimate impact on the Partnerships business of
complying with existing laws and regulations is not always clearly known or determinable due in part to the fact that the Partnerships operations may change over time and certain implementing regulations for laws, such as the CAA, have not yet
been finalized, are under governmental or judicial review or are being revised. These laws and regulations could result in increased capital, operating and compliance costs.

The Partnership entered into a settlement agreement with the Illinois Environmental Protection Agency in August 2013 requiring it to connect a
device at the East Dubuque Facility to an ammonia safety flare by December 1, 2015. The Partnership estimates the cost of the project required by the settlement agreement as being approximately $300,000.

Note 10  Partners Capital and Partnership Distributions

The Partnerships policy is to distribute all of the cash available for distribution which it generates each quarter. Cash available for
distribution for each quarter will be determined by the board of directors (the Board) of the General Partner following the end of each quarter. The Partnership expects that cash available for distribution for each quarter will generally
be calculated as the cash it generates during the quarter, less cash needed for maintenance capital expenditures not funded by capital proceeds, debt service and other contractual obligations, and reserves for future operating or capital needs that
the Board of the General Partner deems necessary or appropriate. The Partnership does not intend to maintain excess distribution coverage for the purpose of maintaining stability or growth in its quarterly distribution or otherwise to reserve cash
for distributions, nor does it intend to incur debt to pay quarterly distributions. The Partnership has no legal obligation to pay distributions. Distributions are not required by the Partnerships partnership agreement and the
Partnerships distribution policy is subject to change at any time at the discretion of the Board of the General Partner. Any distributions made by the Partnership to its unitholders will be done on a pro rata basis. At December 31, 2013
and 2012, the Partnership had outstanding 193,632 and 154,938 unit-settled phantom units, respectively. Each phantom unit entitles the holder to payments in amounts equal to the amounts of any distributions made to an outstanding unit by the
Partnership. Payments to outstanding phantom units are not subtracted from operating cash flow in the calculation of cash available for distribution, but the payments made to phantom unitholders are recorded as distributions for accounting purposes.
For information on the announcement of cash distributions refer to Note 17 Subsequent Events.

The following is a
summary of cash distributions paid to common unitholders and holders of phantom units during the calendar years ended December 31, 2013 and 2012 for the respective quarters to which the distributions relate:

Shelf Registration Statement

On April 4, 2013, the Partnership and Finance Corporation filed a shelf registration statement with the SEC, which allowed the Partnership
or any selling securityholder to offer and sell up to $500.0 million in aggregate initial offering price of common units or debt securities. In March 2014, the partnership post-effectively amended the shelf registration statement. Once the
post-effective amendment has been declared effective, the shelf registration statement will allow for the offer and sell of up to $500 million in the aggregate of securities comprised of (i) $265.5 million of common units and debt securities to
be offered and sold by the Partnership in primary offerings and (ii) up to 12.5 million common units to be offered and sold by RNHI in secondary offerings. The debt securities may be issued by the Partnership and co-issued by Finance
Corporation, and may be guaranteed by one or more of the Partnerships subsidiaries. Each subsidiary guarantor of the debt securities would be exempt from reporting under the Securities Exchange Act of 1934, as amended (the Exchange
Act) pursuant to Rule 12h-5 under the Exchange Act. The Partnership has no independent assets or operations, the guarantees of its subsidiary guarantors are joint and several and full and unconditional, subject to customary automatic release
provisions. The Partnerships subsidiaries other than its subsidiary guarantors are minor and there are no significant restrictions on the Partnerships ability or the ability of any subsidiary guarantor to obtain funds from its
subsidiaries.

Note 11  Long-Term Incentive Equity Awards and Other Equity Based Compensation

On November 2, 2011, the Board of the General Partner adopted the Rentech Nitrogen Partners, L.P. 2011 Long-Term Incentive Plan (the
2011 LTIP). The General Partners officers, employees and non-employee directors, as well as other key employees of Rentech, the indirect parent of the General Partner, and certain of the Partnerships other affiliates who make
significant contributions to its business, are eligible to receive awards under the 2011 LTIP, thereby linking the recipients compensation directly to the Partnerships performance. The 2011 LTIP provides for the grant of unit awards,
restricted units, phantom units, unit options, unit appreciation rights, distribution equivalent rights, profits interest units and other unit-based awards. Subject to adjustment in the event of certain transactions or changes in capitalization,
3,825,000 common units may be delivered pursuant to awards under the 2011 LTIP.

The accounting guidance requires all share-based
payments, including grants of stock options, to be recognized in the statement of income, based on their fair values. Some grants under the 2011 LTIP are marked-to market at each reporting date. Most grants have graded vesting provisions where an
equal number of shares vest on each anniversary of the grant date. Rentech and RNP allocate the total compensation cost on a straight-line attribution method over the requisite service period. Equity based compensation expense that the Partnership
records is included in selling, general and administrative expense.

During the calendar years ended December 31, 2013 and 2012 and
the three months ended December 31, 2011, charges associated with all equity-based grants issued by RNP under the 2011 LTIP were recorded as follows:

During the calendar year ended December 31, 2013, the Partnership issued 116,508 unit-settled phantom
units (which entitle the holder to distribution rights during the vesting period) covering the Partnerships common units. 108,218 of the phantom units are time-vested awards that vest in three equal annual installments. 2,780 of the phantom
units were time-vested awards issued to the directors that vested on the one-year anniversary of the Offering. The phantom unit grants resulted in unit-based compensation expense of $1.2 million for the calendar year ended December 31, 2013.

As of December 31, 2013, there was $3.0 million of total unrecognized compensation cost related to non-vested share-based
compensation arrangements from previously granted phantom units. That cost is expected to be recognized over a weighted-average period of 2.2 years.

During the calendar year ended December 31, 2013, the Partnership issued a total of 5,510 common units which were fully vested at date of
grant. The common units were issued to the directors and resulted in unit-based compensation expense of $0.3 million.

Note 12  Employee Benefit Plans

Defined Contribution Plan

Salaried
employees participate in Rentechs 401(k) plan while union employees participate in the Partnerships 401(k) plan. Salaried employees who are at least 18 years of age and have 60 days of service are eligible to participate in
Rentechs plan on the first of the month following 60 days and share in the employer matching contribution. During 2013, Rentech matched 100% of the first 3% and 50% of the next 3% of the participants salary deferrals. Participants are
fully vested in both matching and any discretionary contributions made to the plan by Rentech. Union employees who are at least 18 years of age and have been employed by RNP for 120 days are eligible to participate in the Partnerships plan.

Notes to Consolidated Financial Statements  Continued



October 20, 1999 receive a Partnership contribution of 4% of compensation and a Partnership match of 50% of the first 2% of the participants salary deferrals. Union employees hired
after October 19, 1999 receive a Partnership matching contribution of 75% of the first 6% of the participants salary deferrals. Participants are fully vested in both matching and any discretionary contributions made to the plan by RNP.
The Partnership contributed $0.8 million, $0.5 million, $0.1 million and $0.5 million to the plans for the calendar years ended December 31, 2013 and 2012, the three months ended December 31, 2011 and the fiscal year ended
September 30, 2011, respectively. Additionally, the Partnership has a savings and profit sharing plan for the benefit of qualified employees at the Pasadena Facility. The plan cost for the calendar year ended December 31, 2013 and for the
period November 1, 2012 through December 31, 2012 was approximately $0.1 million and $9,000 respectively.

Pension Plans

Reporting and disclosures related to pension and other postretirement benefit plans require that companies include an additional asset or
liability on the balance sheet to reflect the funded status of retirement and other postretirement benefit plans, and a corresponding after-tax adjustment to accumulated other comprehensive income.

The Partnership has two noncontributory pension plans (the Pension Plans), which cover either hourly paid employees represented by
collective bargaining agreements in effect at its Pasadena Facility or hourly employees at its Pasadena Facility who have 1,000 hours of service during a year of employment.

Postretirement Benefits

The
Partnership has a postretirement benefit plan (the Postretirement Plan) for certain employees at its Pasadena Facility. The plan provides a fixed dollar amount to supplement payment of eligible medical expenses. The amount of the
supplement under the plan is based on years of service and the type of coverage elected (single or family members and spouses). Participants are eligible for supplements at retirement after age 55 with at least 20 years of service to be paid until
the attainment of age 65 or another disqualifying event, if earlier.

The Pension Plans and the Postretirement Plan were acquired as part
of the Agrifos Acquisition. The following tables summarize the projected benefit obligation, the assets and the funded status of the Pension Plans and the Postretirement Plan at December 31, 2013 and 2012:

Partnership and unallocated expenses represent costs that relate directly to the Partnership and its
subsidiaries but are not allocated to a segment. Partnership and unallocated expenses recorded in selling, general and administrative expenses consist primarily of business development expenses for the Partnership; unit-based compensation expense
for executives of RNP; services from Rentech for executive, legal, finance, accounting, human resources, and investor relations support in accordance with the services agreement between the Partnership and Rentech; audit and tax fees; legal fees;
compensation for Partnership level personnel; board expense; and certain insurance costs. Partnership and unallocated expenses recorded in other expense represent primarily loss on debt extinguishment partially offset by fair value adjustment to
earn-out consideration. Unallocated interest expense represents primarily interest expense on the Notes.

Note 15  Net Income Per Common Unit

The following table sets forth the computation of basic and diluted net income per common unit (in thousands, except for per unit
data).

For the years ended December 31, 2013 and 2012, 0 and approximately 149,000 phantom units, respectively,
were excluded from the calculation of diluted net income per common unit because their inclusion would have been anti-dilutive. For the period November 9, 2011 through December 31, 2011, no phantom units were excluded from the calculation
of diluted net income per common unit.

The gross loss during the three months ended December 31, 2013 was primarily attributable to
(i) turnaround expenses at the East Dubuque Facility and the Pasadena Facility of approximately $7.8 million and $1.7 million, respectively, (ii) a write-down of the Pasadena Facilitys inventory of approximately $5.1 million,
(iii) fixed operating costs while the East Dubuque Facility was idle of approximately $4.2 million, and (iv) the $1.0 million insurance deductible for the fire which occurred in November 2013 at the East Dubuque Facility.

Note 17  Subsequent Events

On February 13, 2014, the Partnership announced a cash distribution to its common unitholders for the period October 1, 2013 through
and including December 31, 2013 of $0.05 per common unit which resulted in total distributions in the amount of approximately $2.0 million, including payments to phantom unitholders. The cash distribution was paid on February 28, 2014 to
unitholders of record at the close of business on February 24, 2014.

On March 7, 2014 the Borrowers entered into the First
Amendment to the 2013 Credit Agreement (the First Amendment). In certain circumstances the First Amendment replaces the financial test that the Partnership must satisfy for any borrowing from the Secured Leverage Ratio to a Fixed
Charge Coverage Ratio (each as defined in the 2013 Credit Agreement) for the period from the date of the amendment until immediately prior to the time the Partnership reports its fiscal year 2014 annual results (the FCCR End
Date). The Fixed Charge Coverage Ratio that the Partnership has to meet from the date of the First Amendment through the date immediately prior to reporting the Partnerships 2014 first quarter results is 2.00 to 1.00, and thereafter
through the FCCR End Date is 2.25 to 1.00. For the year ended December 31, 2013, the Partnerships Fixed Charge Coverage Ratio was 3.27 to 1.00.

The First Amendment also modifies for a specified period the financial test applicable to the announcement or payment of a distribution. In
the event that the Partnership has no amounts outstanding under the 2013 Credit Agreement on the date of the announcement or payment of a distribution, the minimum Fixed Charge Coverage Ratio that it has to meet in order to pay distributions in the
period from the date of the First Amendment through the date immediately prior to reporting the Partnerships 2014 first quarter results is 2.00 to 1.00, and thereafter through the FCCR End Date is 2.25 to 1.00. If there is any amount
outstanding under the 2013 Credit Agreement on the date of the announcement or payment of a distribution from the period beginning with the date of the First Amendment through the FCCR End Date, the Partnership must have a Secured Leverage Ratio not
in excess of 3.75 to 1.00. Following the FCCR End Date, to announce or pay a distribution the Partnership must have a Secured Leverage Ratio not in excess of 3.75 to 1.00. In addition, before the Partnership can make distributions, the Partnership
must have at least $8.75 million available to be drawn under the 2013 Credit Agreement on a pro forma basis.

ITEM 9A.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, or DCP, that are designed to ensure that information required to be disclosed by us in reports
that we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and that such information is
accumulated and communicated to our management, including our general partners principal executive officer, or Chief Executive Officer, and principal financial officer, or Chief Financial Officer, as appropriate, to allow for timely decisions
regarding required disclosure. In designing and evaluating DCP, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.
Management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

In the
Original 10-K, our Chief Executive Officer and Chief Financial Officer concluded that our DCP were effective as of December 31, 2013. Subsequent to that evaluation, management identified the material weaknesses in internal control over
financial reporting, or ICFR, described below, and our Chief Executive Officer and Chief Financial Officer concluded that our DCP were not effective as of December 31, 2013.

Managements Annual Report on Internal Control Over Financial Reporting (Restated)

Management is responsible for establishing and maintaining adequate ICFR (as defined in Rule 13a-15(f) of the Exchange Act). Our ICFR is
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our ICFR includes policies and
procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. Because of its inherent limitations, ICFR may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies and procedures may
deteriorate. However, these inherent limitations are known features of the financial reporting process, and it is possible to design into the process safeguards to reduce, though not eliminate, the risk.

Management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of
our ICFR as of December 31, 2013. Management based its assessment on criteria established in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO.

We identified the following material weaknesses that existed at December 31, 2013. A material weakness is a deficiency, or combination of
deficiencies, in ICFR, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

We did not design and maintain effective internal controls over (i) the review of the cash flow forecasts used in the accounting for
goodwill, (ii) the determination of the goodwill impairment charge in accordance with generally accepted accounting principles, and (iii) maintaining documentation supporting managements review of events and changes in circumstances
that indicate it is more likely than not that a goodwill impairment has occurred between annual impairment tests. Specifically, with respect to (i) and (ii), we did not design and maintain effective internal controls related to determining the
carrying value and fair value of reporting units for the purpose of performing goodwill impairment testing, documenting managements review of assumptions used in the forecasts, and verifying that data contained in reports provided by
specialists reconcile to the information provided to those specialists.

These control deficiencies did not result in a material
misstatement to our consolidated financial statements for the year ended December 31, 2013. However, these control deficiencies, if unremediated, could, in another reporting period, result in a material misstatement to the annual or interim
consolidated financial statements that would not be prevented or detected by the controls. Accordingly, our management has determined that these control deficiencies constitute material weaknesses.

In Managements Annual Report on Internal Control Over Financial Reporting included in our Original 10-K, our management, including our
Chief Executive Officer and Chief Financial Officer, concluded that we maintained effective ICFR as of December 31, 2013. Management subsequently concluded that the material weaknesses described above existed as of December 31, 2013. As a
result, we have concluded we did not maintain effective ICFR as of December 31, 2013 based on the criteria in Internal Control  Integrated Framework (1992) issued by COSO. Accordingly, management has restated its report on
ICFR.

##### Table of Contents

The effectiveness of our internal control over financial reporting as of December 31, 2013
has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Plan for Remediation of the Material Weaknesses

We have implemented and are continuing to implement a number of measures to address the material weaknesses identified. Specifically, we are
designing additional controls over documentation and review of the inputs and results of our cash flow forecasts, the use of the work of specialists and the identification of events and changes in circumstances that may indicate potential impairment
of goodwill. These controls are expected to include the implementation of additional review activities by qualified personnel and additional documentation and support of conclusions with regard to accounting for goodwill impairment calculations. We
are also designing additional controls around identification and documentation relating to accounting for goodwill impairment. These controls are expected to include the implementation of additional review activities by qualified personnel,
additional documentation and the development and use of checklists and procedures related to accounting for goodwill impairment calculations. We are in the process of implementing our remediation plan, and expect the control weaknesses to be
remediated in the coming reporting periods. However, we are unable at this time to estimate when the remediation will be completed.

The
process of designing and implementing an effective financial reporting system is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources
to maintain a financial reporting system that is adequate to satisfy our reporting obligations. As we continue to evaluate and take actions to improve our ICFR, we may determine to take additional actions to address control deficiencies or determine
to modify certain of the remediation measures described above. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to remediate the material weaknesses we have identified or
avoid potential future material weaknesses.

Changes in Internal Control over Financial Reporting

There were significant changes in our ICFR during the quarter ended December 31, 2013 that materially affected, or are reasonably likely
to materially affect, our ICFR. During the quarter ended December 31, 2013, we completed the integration of RNPLLCs operations, processes, and internal controls.
