FOR IMMEDIATE RELEASE

Rentech Announces Results for Third Quarter 2013

LOS ANGELES, CA (November 7, 2013) – Rentech, Inc. (NASDAQ: RTK) today announced its results for the three and nine months ended September 30, 2013. Rentech owns and operates wood fibre processing and nitrogen fertilizer businesses. Rentech also owns technologies designed to produce certified synthetic fuels and renewable power, when integrated with third-party technologies, that it is seeking to license or sell.

Rentech’s financial results reflect the consolidated results of Rentech, Inc. and its subsidiaries, including its wood fibre processing business and Rentech Nitrogen Partners, L.P. (Rentech Nitrogen). The results of the wood fibre processing business are reported as two operating segments: Fulghum Fibres (wood chipping) and wood pellets. The results of Rentech Nitrogen are reported as the nitrogen products manufacturing subsidiary of Rentech, which includes two operating segments: the East Dubuque Facility and the Pasadena Facility. Results of the energy technologies business are reported in a separate segment.

D. Hunt Ramsbottom, President and CEO of Rentech, said, “We are extremely pleased with the performance in our wood fibre processing business, as Fulghum Fibres generated solid gross margin of 19% and progress continues to be made on our two wood pellet production facilities. Fulghum remains on track to generate annualized revenues and EBITDA of $95 million and $20 million, respectively. Construction of the Atikokan and Wawa pellet facilities in Eastern Ontario commenced in August, and we remain on schedule to meet our pellet delivery obligations to OPG and Drax next year.”

Mr. Ramsbottom continued, “The nitrogen fertilizer business reported cash distributions that were in line with our expectations reflected in our guidance of August 8. Although prices for our products, and all nitrogen products, have declined significantly from earlier in the year, we expect the nitrogen market to improve during the fourth quarter as we believe buyers are deferring additional purchases until this year’s late harvest is completed. This could lead to improved pricing and volumes as we move into fall and spring application periods.” Mr. Ramsbottom added, “The turnaround at the East Dubuque Facility was completed safely and on time. We’re now in the commissioning phase of our ammonia production and storage capacity expansion project at the facility. We expect to commence the ammonium sulfate expansion and reliability enhancement projects at our Pasadena Facility next month. The additional volume from these expansion projects should position us well in 2014.”

Financial Highlights

Operating loss for the three months ended September 30, 2013 was $20.2 million, compared to operating income of $16.6 million in the prior-year period, comprised of the following:

Consolidated Adjusted EBITDA for the three months ended September 30, 2013 was $11.5 million, a decline of $9.4 million compared to the prior-year period, which included the following:

Net loss for the three months ended September 30, 2013 was $14.6 million or ($0.06) per basic share. Excluding the loss on goodwill impairment, gain on fair value adjustment to earn-out consideration, gain on sale of the Natchez property, and an income tax benefit, net income allocated to common shareholders for the current period was $7.6 million or $0.03 per basic share. A reconciliation of net income exclusive of these items is provided below. This compares to net income of $4.3 million or $0.02 per basic share for the same period last year.

Fulghum Fibres

Fulghum Fibres generated revenues of $22.4 million for the three months ended September 30, 2013. Gross profit was $4.3 million for the period. SG&A and interest expenses for the period were $1.3 million and $0.7 million, respectively.

Wood Pellets

The wood pellets segment incurred SG&A expenses of $2.4 million for the three months ended September 30, 2013, which included acquisition-related and development costs associated with the Company’s two previously announced pellet projects in Eastern Canada, as well as other costs for the development of the Company’s wood pellet business.

Nitrogen Products Manufacturing

The nitrogen products manufacturing business generated revenues of $93.3 million, compared to $60.1 million for the comparable period in the prior year. Revenues increased due to the contribution of $42.7 million from the Pasadena Facility, partially offset by a 16% decline in revenues from the East Dubuque Facility. Product prices in the current period were lower than in the prior year, having been negatively affected by a delayed spring application season and significantly higher urea exports from China offered at competitive prices. Lower ammonia volumes in the third quarter were partly a consequence of holding a portion of inventory to meet the expected increase in demand for the fall 2013 application season, as production was restricted due to the October turnaround of the East Dubuque Facility. Deliveries of UAN were higher than expected, shifting revenue from the fourth quarter to the current period.

During the three months ended September 30, 2013, Rentech Nitrogen generated an operating loss of $18.3 million, compared to $29.2 million of operating income during the comparable period in the prior year. The primary cause of the operating loss in the current period was a loss of $30.0 million due to the impairment of goodwill related to the Pasadena Facility. The operating loss was also increased by lower gross profits at the East Dubuque Facility, negative gross margin at the Pasadena Facility that reflected a write-down of product inventories, and the addition of SG&A expenses and depreciation and amortization expenses for the Pasadena Facility.

Adjusted EBITDA for the three months ended September 30, 2013 was $16.1 million, compared to $32.9 million in the corresponding period in 2012. Adjusted EBITDA excluding Partnership level expenses totaled $18.0 million for the current period. The East Dubuque Facility and the Pasadena Facility reported $25.8 million and ($7.8) million in EBITDA, respectively, during the three months ended September 30, 2013. Further explanation of Adjusted EBITDA, a non-GAAP financial measure, has been included below in this press release.

Gross margin for the three months ended September 30, 2013 was 18%, compared to 58% for the same period last year. Gross margin at the East Dubuque Facility was 50% for the current period, compared to 58% for the prior-year period, due to lower product prices and higher natural gas prices, partially offset by lower depreciation expense. Gross loss margin at the Pasadena Facility was 19% for the current period, which reflected inventory write-downs and lower margins on sales of products that were produced from higher-cost raw materials purchased earlier in the year. During the quarter, the Partnership incurred a write-down of ammonium sulfate inventories of approximately $5.0 million because the costs of raw materials purchased in prior months and reflected in inventory were higher than current and projected market prices. Gross loss margin excluding the inventory write-down at the Pasadena Facility was 8%, while gross margin at Rentech Nitrogen excluding the inventory write-down was 23%.

SG&A expenses were $4.1 million for the three months ended September 30, 2013, compared to $5.5 million for the prior-year period. The decrease was primarily due to a $2.0 million decline in Partnership level expenses for business development and unit-based compensation, and lower fees for professional services and unused credit facility fees at the East Dubuque Facility, partially offset by the addition of $1.2 million of SG&A expenses from the Pasadena Facility.

Due to a reduced outlook for profitability at the Pasadena Facility compared to projections made when the Partnership acquired Agrifos, Rentech Nitrogen performed an impairment test for goodwill and determined that the carrying amount of the reporting unit exceeded its fair value. As a result, the Partnership recorded a loss due to goodwill impairment of $30.0 million at its Pasadena Facility during the period. The $30.0 million charge is the Partnership’s best estimate of the probable loss and is subject to further adjustments as the goodwill impairment analysis is finalized at fiscal year-end.

Interest expense was $4.0 million for the three months ended September 30, 2013, compared to $0 for the prior-year period. The increase was attributable to debt incurred for the purchase of the Pasadena Facility and to fund expansion projects at the East Dubuque and Pasadena Facilities.

Rentech Nitrogen realized a non-cash gain of $0.3 million for the three months ended September 30, 2013 as a result of a decrease in the potential earn-out consideration related to the acquisition of Agrifos. The reduction in fair value was primarily due to lower results in 2013 caused by a delayed and abbreviated spring application season and higher levels of urea exports from China, suppressing product prices, and reduced expectations for profits from the Pasadena Facility.

Energy Technologies

The energy technologies segment includes SG&A (including costs formerly booked as research and development (R&D) expenses) related to the Company’s technologies that are designed to convert carbon-bearing solids or gases into hydrocarbons and electric power. The segment incurred SG&A expenses of $1.8 million during the current period, compared to $0.7 million for the prior-year period. SG&A expenses increased primarily due to the inclusion of $1.1 million of costs for activities that were previously reported as R&D expenses. These former research and development expenses include costs in support of de-commissioning the PDU, costs associated with efforts to sell and obtain partners for the PDU and the Company’s energy technologies, patent protection expenses, taxes, insurance costs, security and other administrative costs of energy technology facilities and sites. R&D expenses for the energy technologies segment were zero for the three months ended September 30, 2013, since all R&D activity ceased in the first quarter of 2013. R&D expenses for the prior-year period were $5.6 million, which were entirely related to the Company’s alternative energy technologies. During the three months ended September 30, 2013, the segment sold the Natchez site for proceeds of $8.6 million and realized gains of $6.3 million.

Nine months ended September 30, 2013

Consolidated revenues for the nine months ended September 30, 2013 increased by $126.1 million to $295.6 million compared to the prior-year period, comprised of:

Page 3 of 15

Gross profit for the nine months ended September 30, 2013 was $86.3 million, a decrease of $17.0 million compared to the prior-year period, and which included the following:

Operating income for the nine months ended September 30, 2013 was $6.9 million, a decline of $45.7 million compared to the prior-year period, comprised of the following:

Consolidated Adjusted EBITDA for the nine months ended September 30, 2013 was $49.3 million, compared to $63.8 million for the prior-year period, which included the following:

For the nine months ended September 30, 2013, the Company recorded a net income tax benefit of approximately $26.7 million which is comprised of an income tax benefit for Rentech of approximately $27.1 million and an income tax expense for Rentech Nitrogen of approximately $0.4 million. The income tax benefit for Rentech was due to the release of a valuation allowance of $27.2 million that had been recorded against Rentech’s net operating loss carryforwards. The release of the valuation allowance resulted from the recording of deferred tax liabilities related to the Fulghum Fibres acquisition.

Net income for the nine months ended September 30, 2013 was $13.0 million or $0.06 per basic share. Excluding loss on goodwill impairment, loss on debt extinguishment, the gain on fair value adjustment to earn-out consideration, the gain on sale of the Natchez property, and the income tax benefit, net income allocated to common shareholders for the current period was $10.5 million or $0.05 per basic share. This compares to net income of $10.5 million or $0.05 per basic share for the same period last year.

Fulghum Fibres

Fulghum Fibres generated revenues of $38.5 million from May 1, 2013 through September 30, 2013. Gross profit was $6.7 million for the period. SG&A and interest expenses for the period were $2.1 million and $1.3 million, respectively.

Wood Pellets

The wood pellets segment incurred SG&A expenses of $4.2 million for the nine months ended September 30, 2013, which included acquisition-related and development costs associated with the Company’s two previously announced pellet projects in Eastern Canada as well as other costs for the development of the Company’s wood fibre processing business.

Nitrogen Products Manufacturing

The nitrogen products manufacturing business generated revenues of $256.8 million, compared to $169.2 million for the comparable period in the prior year. Revenues increased due to the contribution of $110.0 million of revenues from the Pasadena Facility, partially offset by a 13% decline in revenues from the East Dubuque Facility. Results in the current period were significantly impacted by unfavorable weather. In the spring of this year, product deliveries from both facilities were reduced and delayed by wet weather which caused a delayed and abbreviated planting season and lower product demand and prices. Significant increases in exports of urea from China also contributed to the downward pressure on nitrogen pricing. Furthermore, in anticipation of lower production due to the October turnaround of the East Dubuque Facility, a portion of ammonia inventory was held to meet the expected increase in demand for the fall 2013 application season. These effects were partially offset by higher deliveries of UAN in the third quarter of 2013, shifting expected revenue from the fourth quarter to the current period.

Page 4 of 15

During the nine months ended September 30, 2013, Rentech Nitrogen generated operating income of $32.7 million compared to $90.3 million during the comparable period in the prior year. Operating income in the current period was reduced by lower gross profits at the East Dubuque Facility, negative gross margin that reflected write-downs of product inventories and loss on goodwill impairment at the Pasadena Facility, and the addition of SG&A expenses and depreciation and amortization expenses for the Pasadena Facility.

Adjusted EBITDA for the nine months ended September 30, 2013 was $75.1 million, compared to $99.7 million in the corresponding period in 2012. Adjusted EBITDA excluding Partnership level expenses, totaled $81.6 million for the current period. The East Dubuque Facility and the Pasadena Facility reported $84.2 million and ($2.6) million in Adjusted EBITDA, respectively, during the nine months ended September 30, 2013. Further explanation of Adjusted EBITDA, a non-GAAP financial measure, has been included below in this press release.

Gross margin for the nine months ended September 30, 2013 was 31%, compared to 61% for the same period last year. Gross margin at the East Dubuque Facility was 55% for the current period, compared to 61% for the prior-year period, primarily due to lower ammonia sales volume and prices, and higher natural gas costs, partially offset by lower depreciation expense. Gross loss margin at the Pasadena Facility was 2% for the current period, which reflected inventory write-downs and sales of products that were produced from higher-cost raw materials. During the nine months ended September 30, 2013, the Partnership incurred write-downs of sulfur and sulfuric acid inventories of approximately $0.5 million, and of ammonium sulfate inventories of approximately $6.8 million due to lower market prices. Gross margin excluding the inventory write-down at the Pasadena Facility was 5%, while gross margin at Rentech Nitrogen excluding the inventory write-down was 34%.

SG&A expenses were $13.7 million for the nine months ended September 30, 2013, compared to $12.0 million for the prior-year period. The increase was primarily due to the addition of $3.8 million of SG&A expenses from the Pasadena Facility, partially offset by a $1.0 million decrease in Partnership level expenses and a $1.1 million decline in expenses at the East Dubuque Facility primarily due to lower unused credit facility fees and legal expenses.

Due to a reduced outlook for profitability at the Pasadena Facility compared to projections made when the Partnership acquired Agrifos, Rentech Nitrogen performed an impairment test for goodwill and determined that the carrying amount of the reporting unit exceeded its fair value. As a result, the Partnership recorded a loss due to goodwill impairment of $30.0 million at its Pasadena Facility during the period. The $30.0 million charge is the Partnership’s best estimate of the probable loss and is subject to further adjustments as the goodwill impairment analysis is finalized at fiscal year-end.

Interest expense was $9.7 million for the nine months ended September 30, 2013, compared to $0.2 million for the prior-year period. The increase was attributable to debt incurred for the purchase of the Pasadena Facility and expansion projects at the East Dubuque and Pasadena Facilities.

Rentech Nitrogen realized a non-cash gain of $4.9 million for the nine months ended September 30, 2013 as a result of a decrease in the potential earn-out consideration related to the acquisition of Agrifos. The reduction in fair value was primarily due to lower results in 2013 caused by a delayed and abbreviated spring application season and higher levels of urea exports from China, suppressing product prices, and reduced expectations for profits from the Pasadena Facility.

Energy Technologies

The segment incurred SG&A expenses of $5.5 million during the current period, compared to $3.3 million for the prior-year period. SG&A expenses increased primarily due to the inclusion of $3.1 million in costs for activities that were previously reported as R&D expenses, partially offset by a decrease in project development costs of approximately $0.9 million. These former R&D expenses included costs in support of de-commissioning the PDU, costs associated with efforts to sell and obtain partners for the PDU and the Company’s energy technologies, patent protection expenses, taxes, insurance costs, security and other administrative costs of energy technology facilities and sites. R&D expenses for the energy technologies segment were $5.7 million for the nine months ended September 30, 2013, all of which were incurred in the first three months of the year. R&D expenses for the prior-year period were $14.7 million. During the nine months ended September 30, 2013, the segment sold the Natchez site for proceeds of $8.6 million and realized gains of $6.3 million.

Wood Fibre Processing Business Update

Update on Pellet Projects

At the inception of the projects in 2012, Rentech retained two affiliated firms, AgriRecycle and EAD, who together have 27 years of experience designing and building 11 pellet plants, to perform engineering and project design. After the joint venture (JV) with Graanul Invest (Graanul) was formed in May of this year, Graanul reviewed the engineering and project plans. Rentech and Graanul then jointly decided that AgriRecycle and EAD would continue their work, while the resources of the JV and Graanul would be focused on other projects under development. Since Graanul would not be providing EPC services, the Wawa and Atikokan projects would not be financed and owned by the JV. Rentech will continue to own the projects outright and be responsible for construction. The Rentech team includes the former plant manager, wood yard manager, and manager of capital projects at the Wawa facility, all of whom worked at the plant when it was operated by Weyerhaeuser as an OSB mill processing nearly 750,000 green metric tons of logs annually.

Rentech began construction of the Atikokan and Wawa wood pellet facilities in August and remains on schedule to begin producing wood pellets from these facilities in 2014. Demolition work at the sites has been completed within budget. Rentech has placed orders or received bids for all major equipment, with costs consistent with the budget. The Company has decided to increase capital costs at the Wawa facility, by installing two electric 170 foot radial log cranes, to be purchased from Fulghum Industries, rather than using diesel-powered mobile equipment to manage the wood yard, offloading and feeding. It is expected that the project cost will increase by approximately $8 million due to this decision. Cranes are typically more reliable, safer, reduce emissions, and are significantly less expensive to operate for large capacity facilities such as the Wawa plant. The use of these cranes should result in annual operating cost savings of at least $1 million, with an expected useful life of 20 years or more.

The design of the facilities has been further modified to add capacity, which will increase capital costs. The expected production of the Wawa plant has increased to approximately 450,000 tonnes. The Wawa plant is now expected to supply the entire 400,000 tonnes of annual pellet deliveries to Drax, with 50,000 tonnes available for sale to Drax or other customers. The production of the Atikokan facility is now expected to be approximately 100,000 tonnes, which will fulfill the existing contract with OPG for 45,000 tonnes, with the remaining 55,000 tonnes available for sale to OPG or other customers. When the increased output anticipated from the design changes and the operating efficiencies anticipated from the cranes are balanced against higher capital costs, the expected return profile of the projects remains unchanged, with stabilized annual EBITDA now projected in the range of $17 to $20 million. The projected EBITDA is based on estimated operating income in the range of $8 to $11 million. Further explanation of EBITDA, a non-GAAP financial measure, has been included below in this press release.

Rentech entered the wood fibre processing business to create value by investing in high return projects with stable cash flows and long-term contracts, diversifying the Company’s exposure to commodity fluctuations in the nitrogen business. The Company is pursuing specific opportunities in both wood chipping and pellet operations that could lead to substantial growth. Some of the opportunities depend on the consummation of transactions, the success and timing of which are unpredictable. Rentech believes that an IPO of the fibre business as an MLP is possible, depending on market conditions, and could best be accomplished at a scale somewhat larger than that of the Wawa and Atikokan projects combined with Fulghum Fibres. If the wood fibre processing business is able to achieve a larger scale through development and transactions, Rentech believes that it could accomplish an IPO in approximately 2 years or less.

Revolving Loan Facility

In September 2013, Rentech, Inc. entered into a $100 million revolving loan facility. Proceeds from the facility are intended to be used to fund growth in Rentech’s wood fibre processing business. The facility is collateralized by a portion of the units of Rentech Nitrogen Partners, L.P. owned by a subsidiary of Rentech, Inc. The revolving loan facility has a maturity of three years and an interest rate on outstanding loan amounts of LIBOR plus 4.0% per annum. Rentech drew down $50 million of the facility upon closing of the transaction, with the remaining $50 million of capacity available for future borrowings, so long as certain conditions are satisfied at the time of borrowing. The facility is secured by 15.4 million of the 23.25 million common units of Rentech Nitrogen currently owned by Rentech as initial collateral. Under certain circumstances, up to 19.4 million units may be pledged as collateral. Depending on the market price of the units, among other things, Rentech may be restricted from borrowing the full $100 million maximum amount. Rentech will continue to receive all cash distributions paid on the common units and retain the right to sell units not held as collateral as long as certain conditions outlined in the loan facility are met. Rentech, Inc. is the guarantor of the revolving loan facility.

2013 Outlook

Rentech

Rentech reiterated expectations for Fulghum Fibres for the full year 2013, of approximately $95 million of pro forma revenue and $20 million of pro forma EBITDA, of which Rentech would recognize eight months of results since the acquisition. For the twelve months ending December 31, 2013, Rentech reiterated its guidance of total cash operating expenses for Rentech, including Fulghum Fibres and excluding the nitrogen products manufacturing business, of approximately $34 million.

Rentech Nitrogen

In its press release dated November 7, 2013, Rentech Nitrogen indicated that cash available for distribution for the fourth quarter of 2013 could be as low as zero, and provided an updated outlook.

Based on Rentech Nitrogen’s current guidance, and assuming Rentech’s current ownership of 23.25 million units of Rentech Nitrogen, Rentech’s cash distributions could total approximately $38 million for 2013, assuming that the distribution related to fourth quarter results is zero.
