CLAYTON, Mo. (August 8, 2013) – FutureFuel Corp. (NYSE: FF), a manufacturer of custom and performance chemicals and biofuels, today announced financial results for the three months ended June 30, 2013.

Second Quarter 2013 Financial Highlights (all comparisons are with the second quarter of 2012)

First Half 2013 Financial Highlights (all comparisons are with the first half of 2012)

“We are extremely pleased with our record performance resulting from strong margins in the biofuel segment and solid performance from our chemical segment,” said Lee Mikles, FutureFuel president. “We, like the rest of the biofuel industry, realize the importance that continued support from our legislatures in the Renewable Fuel Mandate and the blenders credit has on our biodiesel business. The chemical pipeline of potential new custom products continues to be strong but we do face challenges in bridging the gap in the volumetric decline of existing chemicals and are diligently working in that effort.”

2013 Regular Cash Dividends

FutureFuel declared normal quarterly dividends of $0.11 per share for 2013. The remaining 2013 dividends will be paid in September and December.

Second Quarter Financial and Business Summary

Revenues for the second quarter of 2013 were $106,063,000 as compared to revenues for the second quarter of 2012 of $103,237,000, an increase of 3%. Revenues from biofuels were up 3% and accounted for 60% of total revenues in the second quarter of 2013 and in the second quarter of 2012. Revenues from chemicals increased 3% and accounted for 40% of total revenues in the second quarter of 2013 and in the second quarter of 2012. Revenue from the bleach activator and the proprietary herbicide and intermediates are together the most significant components of our chemicals business revenue base, accounting for 18% and 23% of total revenues for the second quarter of 2013 and 2012, respectively. Revenues from both of these products have continued to comprise a smaller percentage of our total revenues in 2013 as revenues from our biofuels segment have increased coupled with decreases in the sales of the bleach activator and the proprietary herbicide and intermediates. Revenues from biofuels increased from $62,344,000 in the three months ended June 30, 2012 to $64,037,000 in the three months ended June 30, 2013. We have experienced increased sales quantities in the second quarter of 2013 with the reinstatement of the blenders credit in January 2013 compared to the second quarter of 2012 when the blender credit was not available.

Income from operations increased from $11,572,000 in the three months ended June 30, 2012 to $24,975,000 in the three months ended June 30, 2013. FutureFuel does not report income from operations by segment, but does report segment gross profit. The chemicals segment gross profit increased 31% to $14,784,000 in the three months ended June 30, 2013 from $11,249,000 in the three month ended June 30, 2012. Biofuels segment gross profit increased to $12,842,000 in the three months ended June 30, 2013 from $3,151,000 in the three months ended June 30, 2012. Market conditions were more favorable for biodiesel in 2013 as compared to 2012 largely as a result of the reinstatement of the $1.00 blenders credit in January 2013. Biodiesel profitability in the second quarter of 2012 was negatively impacted due to our inventory of unsold, internally generated RINs. At June 30, 2013 we maintained a minimal inventory of RINs. Also impacting Biofuels gross profit were hedging gains. For the second quarter of 2013 hedging gains totaled $2,327,000 down from a gain of $8,473,000 in the second quarter of 2012.   Chemical segment gross profit increased primarily as a result of three factors. First, the improved economies of scale on fixed resources from the addition of new chemical products and, to a greater degree, continued increased biodiesel production. Second, improved profit from the bleach activator business as the sales price has increased on the customer’s reduced sales demands. Lastly, profit improved with the variation in the product mix sold.

Net income increased from $8,473,000, or $0.20 per diluted share, for the second quarter of 2012 compared with $18,156,000 or $0.42 per diluted share for the second quarter of 2013. This increase was the net result of the factors noted above. Adjusted EBITDA totaled $25,340,000 in the second quarter of 2013 as compared to $5,940,000 in the second quarter of 2012.

Six Month Financial and Business Summary

Revenues for the six months ended June 30, 2013 were $198,228,000 as compared to revenues for the six months ended June 30, 2012 of $188,964,000, an increase of 5%. Revenues from biofuels increased 6% and accounted for 59% of total revenues in the first six months of 2013 as compared to 58% in the first six months of 2012. Revenues from chemicals increased 4% and accounted for 41% of total revenues in the first six months of 2013 as compared to 42% in the first six months of 2012. Revenue from the bleach activator and the proprietary herbicide and intermediates are together the most significant components of our chemicals business revenue base, accounting for 20% of total revenues for the six months ended June 30, 2013 as compared to 23% of total revenues for the six months ended June 30, 2012. These products comprised a smaller percentage of our total revenues in 2013 as revenues from our other custom products have assumed a larger percentage coupled with decreases in the sales of the bleach activator and the proprietary herbicide and intermediates. Revenues from biofuels increased from $109,662,000 in the six months ended June 30, 2012 to $116,066,000 in the six months ended June 30, 2013. The reinstatement of the $1.00 per gallon federal blenders credit in January 2013 along with the government mandated renewable fuel standard for biodiesel combined to improve the economics of biodiesel in 2013. Revenues from biofuels have also been impacted by our sales of refined petroleum products as a supplier on a common carrier pipeline. Such gross sales totaled $8,881,000 in the first six months of 2012 compared to $9,213,000 in the first six of 2013. Such sales generate little gross profit.

Income from operations increased from $22,155,000 in the six months ended June 30, 2012 to $43,925,000 in the six months ended June 30, 2013. FutureFuel does not report income from operations by segment, but does report segment gross profit. The chemicals segment gross profit increased 22% to $27,850,000 in the six months ended June 30, 2013 from $22,918,000 in the six month ended June 30, 2012. Biofuels segment gross profit increased to $21,157,000 in the six months ended June 30, 2013 from $4,283,000 in the six months ended June 30, 2012. This increase was largely a result of a combination of the following: (i) as a result of the retroactive reinstatement of the 2012 $1.00 blenders credit, we recognized a $2,535,000 in profit in the first quarter of 2013. As stated above, this credit will expire at December 31, 2013. No such reduction in cost of goods sold was recognized in the first quarter of 2012; biodiesel profitability in the six months of 2012 was negatively impacted due to our inventory of unsold, internally generated RINs. We do not allocate production costs to internally generated RINs, and, from time to time, we enter into sales of biodiesel on a “RINs-free” basis. Such method of selling results in us maintaining possession of the applicable RINs from the sale. The benefit derived from the eventual sale of the RINs is not reflected in our results of operations until such time as the RIN sale has been completed, which may lead to variability in our reported operating results. At June 30, 2012 we had RINs available for sale which we did not have at June 30, 2013. Overall market conditions were more favorable for biodiesel in 2013 as compared to 2012 largely as a result of the reinstatement of the $1.00 blenders’ credit in effect for 2013, which was not in effect for 2012. Biofuels gross profit was negatively impacted by a reduction in hedging gains. For the first six months of 2013 hedging gains totaled $3,666,000 down from a gain of $5,219,000 in the first six months of 2012.   Chemical segment gross profit increased primarily as a result of the combination of the following: (i) profits realized with the change in product mix; (ii) variability in production expenditures and timing differences in price adjustments to customers for such variability; (iii) improved profit on the bleach activator as sales price has increased on lower sales demands and (iv) as sales in our biofuels segment increased, fixed costs that may have previously been more heavily allocated to the chemicals segment were being allocated in greater proportion to the biofuels segment.

Net income increased from $15,586,000, or $0.38 per diluted share, for the first six months of 2012 compared with $32,206,000 or $0.75 per diluted share for the first six months of 2013. This increase was the net result of the factors noted above. Adjusted EBITDA totaled $43,074,000 in the first six months of 2013 as compared to $22,524,000 in the first six months of 2012.

Capital Expenditures

Capital expenditures were $5,733,000 in the first six months of 2013, compared with $4,068,000 in the first six months of 2012. FutureFuel was reimbursed for a portion of these expenditures by certain customers as summarized in the following table.

An investor should not place undue reliance on any forward-looking statements contained in this document which reflect FutureFuel’s management’s opinions only as of their respective dates. Except as required by law, the company undertakes no obligation to revise or publicly release the results of any revisions to forward-looking statements.

Non-GAAP Financial Measures

In this press release, FutureFuel used adjusted EBITDA as a key operating metric to measure both performance and liquidity. Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA is not a substitute for operating income, net income, or cash flow from operating activities (each as determined in accordance with GAAP), as a measure of performance or liquidity. Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of results as reported under GAAP. FutureFuel defines adjusted EBITDA as net income before interest, income taxes, depreciation, and amortization expenses, excluding, when applicable, non-cash share-based compensation expense, public offering expenses, acquisition-related transaction costs, purchase accounting adjustments, loss on disposal of property and equipment, gains or losses on derivative instruments, other non-operating income or expense, and, in 2013, the impact from the retroactive reinstatement of the 2012 $1.00 biodiesel blenders tax credit. Information relating to adjusted EBITDA is provided so that investors have the same data that management employs in assessing the overall operation and liquidity of FutureFuel’s business. FutureFuel’s calculation of adjusted EBITDA may be different from similarly titled measures used by other companies; therefore, the results of its calculation are not necessarily comparable to the results of other companies.

Adjusted EBITDA allows FutureFuel’s chief operating decision makers to assess the performance and liquidity of FutureFuel’s business on a consolidated basis to assess the ability of its operating segments to produce operating cash flow to fund working capital needs, to fund capital expenditures, and to pay dividends. In particular, FutureFuel management believes that adjusted EBITDA permits a comparative assessment of FutureFuel’s operating performance and liquidity, relative to a performance and liquidity based on GAAP results, while isolating the effects of depreciation and amortization, which may vary among its operating segments without any correlation to their underlying operating performance, and of non-cash stock-based compensation expense, which is a non-cash expense that varies widely among similar companies, and gains and losses on derivative instruments, whose immediate recognition can cause net income to be volatile from quarter to quarter due to the timing of the valuation change in the derivative instruments relative to the sale of biofuel.

A table included in this earnings release reconciles adjusted EBITDA with net income, the most directly comparable GAAP performance financial measure, and a table reconciles adjusted EBITDA with cash flows from operations, the most directly comparable GAAP liquidity financial measure.

Depreciation is allocated to segment costs of goods sold based on plant usage.
