Transaction Overview ??CVR Energy, Inc. has agreed to acquire Gary-Williams Energy Corporation for $525 million in cash plus working capital ??Gary-Williams primary asset -per-day is (“bpd”) a 70,000 located in Wynnewood, Oklahoma — Complexity rating of 9.3 ??CVR Energy will also acquire associated working capital, as determined at closing — Estimated to be approximately $69 million as of November 25, 2011 ??We expect to fund the transaction primarily with cash, combined with approximately $200 million of senior secured financing — $643 million in balance sheet cash at Coffeyville Resources as of September 30, 2011(a) ??We plan to increase our existing asset based credit facility to $400 million??Transaction expected to close December 15th (a) $643 million is net of cash at CVR Partners, LP. 10

Acquisition Rationale ??High quality asset increases CVR s — Pro forma company will have approximately 185,000 bpd of throughput capacity and weighted average complexity of approximately 11.5 ??Strategically positioned in attractive Mid-Continent region — Located in the highly fragmented and historically underserved Group III, PADD II region (same as CVR) ??Significant opportunities to enhance consolidated operations — Ability to expand CVR s existing crude crude slate, leverage our marketing capabilities, reduce duplicative SG&A ??Enhances financial strength and flexibility — Improves credit profile by expanding processing capacity and diversifying asset base (CVR will no longer be a single asset refiner) ??Favorable spread environment and positive industry outlook — WTI/LLS and WTI/Brent pricing dynamics continue to provide favorable Mid-Continent refining environment due to the limited crude pipeline capacity to Gulf Coast (even post Seaway reversal)

Non-GAAP Financial Measures To supplement the actual results in accordance with U.S. generally accepted accounting principles (GAAP), for the applicable periods, the Company also uses certain non-GAAP financial measures as discussed below, which are adjusted for GAAP-based results. The use of non-GAAP adjustments are not in accordance with or an alternative for GAAP. The adjustments are provided to enhance the overall understanding of the Company’sfinancial performance for the applicable periods and are also indicators that management utilizes for planning and forecasting future periods. The non-GAAP measures utilized by the Company are not necessarily comparable to similarly titled measures of other companies. The Company believes that the presentation of non-GAAP financial measures provides useful information to investors regarding the Company’sfinancial condition and results of operations because these measures, when used in conjunction with related GAAP financial measures (i) together provide a more comprehensive view of the Company’score operations and ability to generate cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial and operational planning decisions, and (iii) presents measurements that investors and rating agencies have indicated to management are useful to them in assessing the Company and its results of operations.

Non-GAAP Financial Measures EBITDA: EBITDA represents net income before the effect of interest expense, interest income, income tax expense (benefit) and depreciation and amortization. EBITDA is not a calculation based upon GAAP; however, the amounts included in EBITDA are derived from amounts included in the consolidated statement of operations of the Company. Adjusted EBITDA by operating segment results from operating income by segment adjusted for items that the company believes are needed in order to evaluate results in a more comparative analysis from period to period. Additional adjustments to EBITDA include major scheduled turnaround expense, the impact of the Company’suse of accounting for its inventory under first-in, first-out (FIFO), net unrealized gains/losses on derivative activities, share-based compensation expense, loss on extinguishment of debt, and other income (expense). Adjusted EBITDA is not a recognized term under GAAP and should not be substituted for operating income or net income as a measure of performance but should be utilized as a supplemental measure of financial performance in evaluating our business. First-in, first-out (FIFO): The Company’sbasis for determining inventory value on a GAAP basis. Changes in crude oil prices can cause fluctuations in the inventory valuation of our crude oil, work in process and finished goods, thereby resulting in favorable FIFO impacts when crude oil prices increase and unfavorable FIFO impacts when crude oil prices decrease. The FIFO impact is calculated based upon inventory values at the beginning of the accounting period and at the end of the accounting period.
