NOTES TO THE UNAUDITED PRO FORMA CONSOLIDATED

FINANCIAL STATEMENTS

(1) Organization and Basis of Presentation

The unaudited pro forma consolidated financial statements have been derived from the audited and unaudited historical financial statements of Rentech, Inc. (the “Company”). As a result of the transactions described herein, Rentech Energy Midwest Corporation (“REMC”), an indirect subsidiary of the Company, became a wholly-owned subsidiary of Rentech Nitrogen Partners, L.P. (the “Partnership”).

The unaudited pro forma consolidated financial statements are not necessarily indicative of the results that the Company would have achieved had the transactions described herein actually taken place at the dates indicated, and do not purport to be indicative of future financial position or operating results. The unaudited pro forma consolidated financial statements should be read in conjunction with the historical financial statements of the Company, the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2010 and the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2011.

The pro forma adjustments have been prepared as if the transactions described below had taken place on June 30, 2011, in the case of the unaudited pro forma consolidated balance sheet, or as of October 1, 2009, in the case of the unaudited pro forma consolidated statements of operations.

The unaudited pro forma consolidated financial statements reflect the following transactions, which occurred at the closing of the Partnership’s initial public offering on November 9, 2011 (the “Offering”):

• Rentech Development Corporation (“RDC”), a wholly-owned subsidiary of the Company, converted into a corporation organized under the laws of the State of Delaware;

• RDC contributed the capital stock in REMC to Rentech Nitrogen Holdings, Inc. (“RNHI”), a wholly-owned subsidiary of RDC;

• REMC converted into a limited liability company organized under the laws of the State of Delaware and changed its name to Rentech Nitrogen, LLC;

• REMC’s management services agreement with the Company terminated in accordance with its terms and REMC paid the Company the corporate overhead costs owed by REMC under the agreement, equaling approximately $19.4 million;

• REMC distributed to RNHI all of REMC’s cash, equaling approximately $39.3 million;

• RNHI contributed the member interests in REMC to the Partnership in exchange for (i) 23,250,000 common units; and (ii) the right to receive approximately $34.7 million in cash, in part, as a reimbursement for expenditures made by REMC during the two-year period preceding the Offering for the expansion and improvement of REMC’s facility; for federal income tax purposes, when REMC converted to a limited liability company (as described above), RNHI was treated as having been the party that made such expenditures with respect to the facility;

• The Partnership offered and sold 15,000,000 common units in the Offering, and paid related underwriting discounts and commissions and the estimated expenses of the Offering;

• The Partnership contributed approximately $198.0 million of the net proceeds of the Offering to REMC for

(i) the repayment in full of REMC’s existing term loan and the payment of related fees and expenses, (ii) the payment of expenditures related to REMC’s steam methane reformer tube replacement, (iii) the payment of expenditures related to REMC’s urea expansion project, diesel exhaust fluid build-out and front end engineering and design for REMC’s ammonia capacity expansion project and (iv) for general working capital purposes; and

• The Partnership intends to enter into a new $25.0 million revolving credit facility as soon as practicable following the closing of the Offering, and to pay associated financing costs of approximately $0.4 million.

The Partnership anticipates incurring incremental general and administrative expense as a result of being a publicly traded limited partnership, such as costs associated with Securities and Exchange Commission reporting requirements, including annual and quarterly reports to unitholders, tax return and Schedule K-1 preparation and distribution, independent auditor fees, internal audit costs, directors and officers insurance, investor relations activities and registrar and transfer agent fees. The Partnership estimates that this incremental general and administrative expense will be approximately $3.6 million per year. The unaudited pro forma consolidated financial statements do not reflect this $3.6 million in incremental expense.

(2) Partner Interest

The Partnership currently has two types of partner interests outstanding:

• common units representing limited partner interests, a portion of which the Partnership sold in the Offering (approximately 39.2% of all of the Partnership’s outstanding common units upon the closing of the Offering); and

• a general partner interest, which is not entitled to any distributions, and which is held by the Partnership’s general partner, Rentech Nitrogen GP, LLC, a wholly-owned subsidiary of RNHI.

(3) Pro Forma Consolidated Balance Sheet Adjustments and Assumptions

(a) Reflects the issuance by the Partnership of 15,000,000 common units to the public at an initial offering price of $20.00 per common unit resulting in aggregate gross proceeds of $300.0 million.

(b) Reflects the payment of underwriting commissions of $21.0 million and other estimated offering expenses of $4.0 million for a total of $25.0 million which have been allocated to the newly issued public common units.

(c) Reflects the repayment in full of REMC’s existing term loan, including accrued interest, in the amount of $150.0 million, repayment penalty of $3.0 million and write-off of debt issuance costs of $8.3 million.

(d) Reflects the estimated deferred financing costs of $0.4 million associated with the new revolving credit facility.

(4) Pro Forma Consolidated Statement of Operations Adjustments and Assumptions

(a) Reflects the elimination of historical loan modification costs related to REMC’s term loan.

(b) Reflects increase in salaries for named executive officers that are expected to provide services to the Company and the Partnership and named executive officers that are expected to provide services to the Partnership.

(c) Reflects unit-based compensation expense on grants of Partnership phantom units.

(d) Reflects the elimination of historical interest expense related to REMC’s existing term loan or previous term loans.

(e) Reflects the amortization of related debt issuance costs of the new revolving credit facility over a two year period.

(f) Reflects the estimated commitment fee of 0.5% on the estimated unused portion of the $25.0 million new revolving credit facility.

(g) Reflects the elimination of historical loss on debt extinguishment.

(h) Reflects net loss attributable to noncontrolling interests.

(i) Reflects the elimination of a historical fee related to REMC’s term loan.

(5) Pro Forma Net Income Per Common Share Attributable to the Company

Basic pro forma income (loss) per common share attributable to the Company is calculated by dividing net income (loss) attributable to the Company by the weighted average number of common shares outstanding for the period. Diluted pro forma net income (loss) per common share attributable to the Company is calculated by dividing net income (loss) attributable to the Company by the weighted average number of common shares outstanding plus the dilutive effect, calculated using the “treasury stock” method for the unvested restricted stock units, outstanding stock options and warrants and using the “if converted” method for the convertible debt.
