Note 1 - Description of Business and Basis of Presentation

Description of business

Callon Petroleum Company is an independent oil and natural gas company established in 1950. The Company was incorporated under the laws of the state of Delaware in 1994 and succeeded to the business of a publicly traded limited partnership, a joint venture with a consortium of European investors and an independent energy company. As used herein, the “Company,” “Callon,” “we,” “us,” and “our” refer to Callon Petroleum Company and its predecessors and subsidiaries unless the context requires otherwise.

Callon is focused on the acquisition, development, exploration and exploitation of unconventional onshore, oil and natural gas reserves in the Permian Basin. The Company’s operations to date have been predominantly focused on the horizontal development of several prospective intervals, including multiple levels of the Wolfcamp formation and the Lower Spraberry shales. Callon has assembled a multi-year inventory of potential horizontal well locations and intends to add to this inventory through delineation drilling of emerging zones on its existing acreage and acquisition of additional locations through working interest acquisitions, leasing programs, acreage purchases, joint ventures and asset swaps. 

Basis of presentation

Unless otherwise indicated, all dollar amounts included within the Footnotes to the Financial Statements are presented in thousands, except for per share and per unit data.

The interim consolidated financial statements of the Company have been prepared in accordance with (1) GAAP, (2) the SEC’s instructions to Quarterly Report on Form 10-Q and (3) Rule 10-01 of Regulation S-X, and include the accounts of Callon Petroleum Company, and its subsidiary, Callon Petroleum Operating Company (“CPOC”). CPOC also has subsidiaries, namely Callon Offshore Production, Inc. and Mississippi Marketing, Inc.

These interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The balance sheet at December 31, 2017 has been derived from the audited financial statements at that date. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the year ended December 31, 2018.

In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments, including normal recurring adjustments and all intercompany account and transaction eliminations, necessary to present fairly the Company’s financial position, the results of its operations and its cash flows for the periods indicated. Certain prior year amounts may have been reclassified to conform to current year presentation.

Accounting Standards Updates (“ASUs”)

Recently Adopted ASUs - Revenue Recognition

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 replaced most of the existing revenue recognition requirements in GAAP. The standard can be applied using either the full retrospective approach or a modified retrospective approach at the date of adoption.

Throughout 2015 and 2016, the FASB issued several updates to the revenue recognition guidance in Accounting Standards Codification Topic 606 (“ASC 606”). In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU 2014-09 by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net). Under this update, an entity should recognize revenue to depict the transfer of promised goods

or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing. This update clarifies two principles of ASC 606: identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients. This update applies only to the following areas from ASC 606: assessing the collectability criterion and accounting for contracts that do not meet the criteria for step 1, presentation of sales taxes and other similar taxes collected from customers, non-cash consideration, contract modification at transition, completed contracts at transition and technical correction.

The Company adopted the new standard on January 1, 2018 using the modified retrospective method at the date of adoption and it did not have a material impact on its consolidated financial statements. See Note 2 for additional information on Revenue Recognition.

Recently adopted ASUs - Other

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The objective of the standard is to reduce the existing diversity in practice of several cash flow issues, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payment made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. The guidance in ASU 2016-15 is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted and is to be applied on retrospective basis. The Company adopted this update on January 1, 2018 and it did not have a material impact on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations-Clarifying the Definition of a Business (“ASU 2017-01”). The guidance in ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The guidance provides a screen to determine when a set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The guidance in ASU 2017-01 is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein. The Company adopted this update effective January 1, 2018. The adoption of this update did not have a material impact on its consolidated financial statements.

Recently issued ASUs - Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification (“ASU 2016-02”). In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 (“ASU 2018-01”). In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). Together these related amendments to GAAP represent ASC Topic 842, Leases (“ASC Topic 842”).

ASC Topic 842 requires lessees to recognize lease assets and liabilities (with terms in excess of 12 months) on the balance sheet, disclose key quantitative and qualitative information about leasing arrangements, and permits an entity not to evaluate existing or expired land easements that were not previously assessed under Topic 840. Public entities are required to apply ASC Topic 842 for annual and interim reporting periods beginning after December 15, 2018 with early adoption permitted. The Company expects the adoption of ASC Topic 842 to primarily impact the asset and liability balances on the balance sheet and will continue to evaluate the effect it will have on its consolidated financial statements and related disclosures. As permitted by ASC Topic 842, the Company does not expect to adjust comparative-period financial statements.

Recently issued ASUs - Other

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). The standard is intended to simplify several aspects of the accounting for nonemployee share-based payment transactions for acquiring goods and services from nonemployees, including the timing and measurement of nonemployee awards. The guidance in ASU 2018-06 is effective for public entities for annual reporting periods beginning after December 15, 2018, including interim periods therein. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is currently evaluating the impact of its pending adoption of this guidance on its consolidated financial statements.

Callon Petroleum Company Notes to the Consolidated Financial Statements (All dollar amounts in thousands, except per share and per unit data) Table of Contents

Note 2 - Revenue Recognition

Revenue from contracts with customers

Oil sales

Under the Company’s oil sales contracts it sells oil production at the point of delivery and collects an agreed upon index price, net of pricing differentials. The Company recognizes revenue when control transfers to the purchaser at the point of delivery at the net price received.

Natural gas sales

Under the Company’s natural gas sales processing contracts, it delivers natural gas to a midstream processing entity. The midstream processing entity gathers and processes the natural gas and remits proceeds to the Company for the resulting sale of natural gas. The revenue received from the sale of NGLs is included in the natural gas sales. Under these processing agreements, when control of the natural gas changes at the point of delivery, the treatment of gathering and treating fees are recorded net of revenues. Gathering and treating fees have historically been recorded as an expense in lease operating expense in the statement of operations. The Company has modified the presentation of revenues and expenses to include these fees net of revenues. For the three and six months ended June 30, 2018, $1,952 and $3,204 of gathering and treating fees were recognized and recorded as a reduction to natural gas revenues in the consolidated statement of operations, respectively. For the three and six months ended June 30, 2017, $761 and $1,484 of gathering and treating fees were recognized and recorded as part of lease operating expense in the consolidated statement of operations, respectively.

Production imbalances

Previously, the Company elected to utilize the entitlements method to account for natural gas production imbalances, which is no longer applicable. In conjunction with the Company’s adoption of the new revenue recognition accounting standards, there was no material impact to the financial statements due to this change in accounting for its production imbalances.

Transaction price allocated to remaining performance obligations

For the Company’s product sales that have a contract term greater than one year, it has utilized the practical expedient in Accounting Standards Codification 606-10-50-14, which states the Company is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Prior period performance obligations

The Company records revenue in the month production is delivered to the purchaser. However, settlement statements for sales may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. The Company has existing internal controls for its revenue estimation process and related accruals, and any identified differences between its revenue estimates and actual revenue received historically have not been significant.

Note 3 - Acquisitions 

Acquisitions were accounted for under the acquisition method of accounting, which involves determining the fair value of the assets acquired and liabilities assumed under the income approach.

2018 Acquisitions

On May 23, 2018, the Company entered into a definitive purchase and sale agreement with Cimarex Energy Company for the acquisition of approximately 47,538 gross (28,657 net) acres in the Spur operating area, located in the Delaware Basin, for an aggregate cash purchase price of $570,000, subject to customary purchase price adjustments (the “Cimarex Acquisition”). In connection with the execution of the purchase and sale agreement, the Company paid a deposit in the amount of $28,500, which was recorded as Acquisition deposit on the balance sheet as of June 30, 2018. The Company issued debt and equity to fund, in part, the Cimarex Acquisition. See Notes 5 and 10 for additional information regarding the Company’s debt obligations and equity offerings.

The Company plans to file separate financial statements and pro forma financial information, as required by SEC rules, in a Current Report on Form 8-K within the prescribed 75 day period following consummation of the Cimarex Acquisition.

During the first quarter of 2018, the Company completed acquisitions of additional working interests and acreage in the Company’s existing core operating areas of Monarch and Wildhorse, located in the Permian Basin, for an aggregate total purchase price of approximately $35,900 excluding customary purchase price adjustments.

2017Acquisitions

On February 13, 2017, the Company completed the acquisition of 29,175 gross (16,688 net) acres in the Delaware Basin, primarily located in Ward and Pecos Counties, Texas from American Resource Development, LLC, for total cash consideration of $646,559 excluding customary purchase price adjustments (the “Ameredev Transaction”). The Company funded the cash purchase price with the net proceeds of an equity offering (see Note 10 for additional information regarding the equity offering). The Company obtained an 82% average working interest (75% average net revenue interest) in the properties acquired in the Ameredev Transaction. In December 2016, in connection with the execution of the purchase and sale agreement for the Ameredev Transaction, the Company paid a deposit in the amount of $46,138 to a third party escrow agent, which was recorded as Acquisition deposit on the balance sheet as of December 31, 2016. The following table summarizes the estimated acquisition date fair values of the acquisition:

Evaluated oil and natural gas properties	$	137,368
Unevaluated oil and natural gas properties	509,359
Asset retirement obligations	(168		)
Net assets acquired	$	646,559

On June 5, 2017, the Company completed the acquisition of 7,031 gross (2,488 net) acres in the Delaware Basin, located near the acreage acquired in the Ameredev Transaction discussed above, for total cash consideration of $52,500 excluding customary purchase price adjustments. The Company funded the cash purchase price with its available cash and proceeds from the issuance of an additional $200,000 of its 6.125% senior notes due 2024 (see Note 5 for additional information regarding the Company’s debt obligations).

Unaudited pro forma financial statements

The following unaudited summary pro forma financial information for the periods presented is for illustrative purposes only and does not purport to represent what the Company’s results of operations would have been if the Ameredev Transaction had occurred as presented, or to project the Company’s results of operations for any future periods:

	Three Months Ended			Six Months Ended
	June 30, 2017		(a)	June 30, 2017		(a)
Revenues	$	82,283		$	166,699
Income from operations	23,743			58,650
Income available to common stockholders	31,566			79,529
Net income per common share:
Basic	$	0.16		$	0.40
Diluted	$	0.16		$	0.40

(a) The pro forma financial information was prepared assuming the Ameredev Transaction occurred as of January 1, 2016.

The pro forma adjustments are based on available information and certain assumptions that management believes are reasonable, including revenue, lease operating expenses, production taxes, depreciation, depletion and amortization expense, accretion expense, interest expense and capitalized interest.

The properties associated with the Ameredev Transaction have been commingled with the Company’s existing properties and it is impractical to provide the stand-alone operational results related to these properties.

6.375% senior unsecured notes due 2026 (“6.375% Senior Notes”)

On June 7, 2018, the Company issued $400,000 aggregate principal amount of 6.375% Senior Notes with a maturity date of July 1, 2026 and interest payable semi-annually beginning on January 1, 2019. The net proceeds of the offering, after deducting initial purchasers’ discounts and estimated offering expenses, were approximately $394,000. The 6.375% Senior Notes are guaranteed on a senior unsecured basis by the Company’s wholly-owned subsidiary, Callon Petroleum Operating Company, and may be guaranteed by certain future subsidiaries. The subsidiary guarantor is 100% owned, all of the guarantees are full and unconditional and joint and several, the parent company has no independent assets or operations and any subsidiaries of the parent company other than the subsidiary guarantor are minor.

The Company may redeem the 6.375% Senior Notes in accordance with the following terms: (1) prior to July 1, 2021, a redemption of up to 35% of the principal in an amount not greater than the net proceeds from certain equity offerings, and within 180 days of the closing date of such equity offerings, at a redemption price of 106.375% of principal, plus accrued and unpaid interest, if any, to the date of the redemption, if at least 65% of the principal will remain outstanding after such redemption; (2) prior to July 1, 2021, a redemption of all or part of the principal at a price of 100% of principal of the amount redeemed, plus an applicable make-whole premium and accrued and unpaid interest, if any, to the date of the redemption; and (3) a redemption, in whole or in part, at a redemption price, plus accrued and unpaid interest, if any, to the date of the redemption, (i) of 103.188% of principal if the redemption occurs on or after July 1, 2021, but before July 1, 2022, and (ii) of 102.125% of principal if the redemption occurs on or after July 1, 2022, but before July 1, 2023, and (iii) of 101.063% of principal if the redemption occurs on or after July 1, 2023, but before July 1, 2024, and (iv) of 100% of principal if the redemption occurs on or after July 1, 2024.

Following a change of control, each holder of the 6.375% Senior Notes may require the Company to repurchase all or a portion of the 6.375% Senior Notes at a price of 101% of principal of the amount repurchased, plus accrued and unpaid interest, if any, to the date of repurchase.

6.125% senior unsecured notes due 2024 (“6.125% Senior Notes”)

On October 3, 2016, the Company issued $400,000 aggregate principal amount of 6.125% Senior Notes with a maturity date of October 1, 2024 and interest payable semi-annually beginning on April 1, 2017. The net proceeds of the offering, after deducting initial purchasers’ discounts and estimated offering expenses, were approximately $391,270. The 6.125% Senior Notes are guaranteed on a senior unsecured basis by the Company’s wholly-owned subsidiary, Callon Petroleum Operating Company, and may be guaranteed by certain future subsidiaries. The subsidiary guarantor is 100% owned, all of the guarantees are full and unconditional and joint and several, the parent company has no independent assets or operations and any subsidiaries of the parent company other than the subsidiary guarantor are minor.

On May 19, 2017, the Company issued an additional $200,000 aggregate principal amount of its 6.125% Senior Notes which with the existing $400,000 aggregate principal amount of 6.125% Senior Notes are treated as a single class of notes under the indenture. The net proceeds of the offering, including a premium issue price of 104.125% and after deducting initial purchasers’ discounts and estimated offering expenses, were approximately $206,139. The Company used the proceeds, in part, to fund an acquisition completed on June 5, 2017 (discussed further in Note 3) and for general corporate purposes.

The Company may redeem the 6.125% Senior Notes in accordance with the following terms: (1) prior to October 1, 2019, a redemption of up to 35% of the principal in an amount not greater than the net proceeds from certain equity offerings, and within 180 days of the closing date of such equity offerings, at a redemption price of 106.125% of principal, plus accrued and unpaid interest, if any, to the date of the redemption, if at least 65% of the principal will remain outstanding after such redemption; (2) prior to October 1, 2019, a redemption of all or part of the principal at a price of 100% of principal of the amount redeemed, plus an applicable make-whole premium and accrued and unpaid interest, if any, to the date of the redemption; and (3) a redemption, in whole or in part, at a redemption price, plus accrued and unpaid interest, if any, to the date of the redemption, (i) of 104.594% of principal if the redemption occurs on or after October 1, 2019, but before October 1, 2020, and (ii) of 103.063% of principal if the redemption occurs on or after October 1, 2020, but before October 1, 2021, and (iii) of 101.531% of principal if the redemption occurs on or after October 1, 2021, but before October 1, 2022, and (iv) of 100% of principal if the redemption occurs on or after October 1, 2022.

Following a change of control, each holder of the 6.125% Senior Notes may require the Company to repurchase all or a portion of the 6.125% Senior Notes at a price of 101% of principal of the amount repurchased, plus accrued and unpaid interest, if any, to the date of repurchase.

Restrictive covenants

The Company’s Credit Facility and the indentures governing its 6.125% and 6.375% Senior Notes contain various covenants including restrictions on additional indebtedness, payment of cash dividends and maintenance of certain financial ratios. The Company was in compliance with these covenants at June 30, 2018.

Note 6 - Derivative Instruments and Hedging Activities

Objectives and strategies for using derivative instruments

The Company is exposed to fluctuations in oil and natural gas prices received for its production. Consequently, the Company believes it is prudent to manage the variability in cash flows on a portion of its oil and natural gas production. The Company utilizes a mix of collars, swaps, put and call options and similar derivative financial instruments to manage fluctuations in cash flows resulting from changes in commodity prices. The Company does not use these instruments for speculative or trading purposes.

Counterparty risk and offsetting

The use of derivative instruments exposes the Company to the risk that a counterparty will be unable to meet its commitments. While the Company monitors counterparty creditworthiness on an ongoing basis, it cannot predict sudden changes in counterparties’ creditworthiness. In addition, even if such changes are not sudden, the Company may be limited in its ability to mitigate an increase in counterparty credit risk. Should one of these counterparties not perform, the Company may not realize the benefit of some of its derivative instruments under lower commodity prices while continuing to be obligated under higher commodity price contracts subject to any right of offset under the agreements. Counterparty credit risk is considered when determining the fair value of a derivative instrument; see Note 7 for additional information regarding fair value.

The Company executes commodity derivative contracts under master agreements with netting provisions that provide for offsetting assets against liabilities. In general, if a party to a derivative transaction incurs an event of default, as defined in the applicable agreement, the other party will have the right to demand the posting of collateral, demand a cash payment transfer or terminate the arrangement.

Financial statement presentation and settlements

Settlements of the Company’s derivative instruments are based on the difference between the contract price or prices specified in the derivative instrument and a benchmark price, such as the NYMEX price. To determine the fair value of the Company’s derivative instruments, the Company utilizes present value methods that include assumptions about commodity prices based on those observed in underlying markets. See Note 7 for additional information regarding fair value.

Derivatives not designated as hedging instruments

The Company records its derivative contracts at fair value in the consolidated balance sheets and records changes in fair value as a gain or loss on derivative contracts in the consolidated statements of operations. Cash settlements are also recorded as a gain or loss on derivative contracts in the consolidated statements of operations.

The following table reflects the fair value of the Company’s derivative instruments for the periods presented:

As previously discussed, the Company’s derivative contracts are subject to master netting arrangements. The Company’s policy is to present the fair value of derivative contracts on a net basis in the consolidated balance sheet. The following presents the impact of this presentation to the Company’s recognized assets and liabilities for the periods indicated:

Note 7 - Fair Value Measurements

The fair value hierarchy included in GAAP gives the highest priority to Level 1 inputs, which consist of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable, and these valuations have the lowest priority.

Fair value offinancial instruments

Cash, cash equivalents, and restricted investments. The carrying amounts for these instruments approximated fair value due to the short-term nature or maturity of the instruments.

15

Callon Petroleum Company Notes to the Consolidated Financial Statements (All dollar amounts in thousands, except per share and per unit data) Table of Contents

Debt. The carrying amount of the Company’s floating-rate debt approximated fair value because the interest rates were variable and reflective of market rates.

	June 30, 2018				December 31, 2017
	Carrying Value		Fair Value		Carrying Value		Fair Value

Total	$	988,459	$	1,007,500	$	620,196	$	618,000

(a) Floating-rate debt.

(b) The fair value was based upon Level 2 inputs. See Note 5 for additional information about the Company’s 6.125% and 6.375% Senior Notes.

Assets and liabilities measured at fair value on a recurring basis

Certain assets and liabilities are reported at fair value on a recurring basis in the consolidated balance sheet. The following methods and assumptions were used to estimate fair value:

Commodity derivative instruments. The fair value of commodity derivative instruments is derived using an income approach valuation model that utilizes market-corroborated inputs that are observable over the term of the derivative contract. The Company’s fair value calculations also incorporate an estimate of the counterparties’ default risk for derivative assets and an estimate of the Company’s default risk for derivative liabilities. The Company believes that the majority of the inputs used to calculate the commodity derivative instruments fall within Level 2 of the fair value hierarchy based on the wide availability of quoted market prices for similar commodity derivative contracts. See Note 6 for additional information regarding the Company’s derivative instruments.

The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis:

Assets andliabilitiesmeasured atfairvalue on anonrecurringbasis

Acquisitions. The Company determines the fair value of the assets acquired and liabilities assumed using the income approach based on expected discounted future cash flows from estimated reserve quantities, costs to produce and develop reserves, and oil and natural gas forward prices. The future net revenues are discounted using a weighted average cost of capital. The discounted future net revenues of proved undeveloped and probable reserves are reduced by an additional reserve adjustment factor to compensate for the inherent risk of estimating the value of unevaluated properties. The fair value measurements were based on Level 2 and Level 3 inputs.

Note 8 - Income Taxes

The Company provides for income taxes at the statutory rate of 21%. The statutory rate is adjusted for permanent differences expected to be realized, which primarily relate to non-deductible executive compensation expenses, restricted stock windfalls and shortfalls, and state income taxes.

As a result of the write-down of oil and natural gas properties in the latter part of 2015 and the first half of 2016, the Company incurred a cumulative three year loss. Because of the impact the cumulative loss has on the determination of the recoverability of deferred tax assets through future earnings, the Company assessed the ability to realize its deferred tax assets based on the future reversals of existing

16

Callon Petroleum Company Notes to the Consolidated Financial Statements (All dollar amounts in thousands, except per share and per unit data) Table of Contents

deferred tax liabilities. Accordingly, the Company established a full valuation allowance for the net U.S. federal deferred tax asset in 2015. In subsequent periods where the Company has recorded pre-tax income, it has reversed a portion of the U.S. federal valuation allowance, net of discrete items, to the extent necessary to offset U.S. federal income tax expense on pre-tax income recorded for the period. Income tax expense recorded in this period relates to deferred State of Texas gross margin tax. The valuation allowance was $38,604 as of June 30, 2018. 

Note 9 - Asset Retirement Obligations

The table below summarizes the activity for the Company’s asset retirement obligations:

	Six Months Ended
	June 30, 2018
Asset retirement obligations at January 1, 2018	$	6,020
Accretion expense	424
Liabilities incurred	99
Liabilities settled	(207		)
Sales	(611		)
Revisions to estimate (a)	4,341
Asset retirement obligations at end of period	10,066
Less: Current asset retirement obligations	(2,284		)
Long-term asset retirement obligations at June 30, 2018	$	7,782

(a) Revisions to estimated ARO obligations can result from changes in retirement cost estimates, revisions to estimated inflation rates and changes in the estimated timing of abandonment.

Certain of the Company’s operating agreements require that assets be restricted for abandonment obligations. Amounts recorded in the consolidated balance sheet at June 30, 2018 as long-term restricted investments were $3,393. These assets, which primarily include short-term U.S. Government securities, are held in abandonment trusts dedicated to pay future abandonment costs for several of the Company’s oil and natural gas properties.

Note 10 - Equity Transactions

10% Series A Cumulative Preferred Stock (“Preferred Stock”)

Holders of the Company’s Preferred Stock are entitled to receive, when, as and if declared by the Company’s Board of Directors, out of funds legally available for the payment of dividends, cumulative cash dividends at a rate of 10.0% per annum of the $50.00 liquidation preference per share (equivalent to $5.00 per annum per share). Dividends are payable quarterly in arrears on the last day of each March, June, September and December when, as and if declared by the Company’s Board of Directors. Preferred Stock dividends were $1,824 and $3,647 for the three and six months ended June 30, 2018 and 2017, respectively.

The Preferred Stock has no stated maturity and is not subject to any sinking fund or other mandatory redemption. The Company may, at its option, redeem the Preferred Stock, in whole or in part, at any time on or after May 30, 2018, by paying $50.00 per share, plus any accrued and unpaid dividends to the redemption date.

Following a change of control in which the Company or the acquirer no longer have a class of common securities listed on a national exchange, the Company will have the option to redeem the Preferred Stock, in whole but not in part, for $50.00 per share in cash plus accrued and unpaid dividends (whether or not declared) to the redemption date. If the Company does not exercise its option to redeem the Preferred Stock upon such change of control, the holders of the Preferred Stock have the option to convert the Preferred Stock into a number of shares of the Company’s common stock based on the value of the common stock on the date of the change of control as determined under the certificate of designations for the Preferred Stock. If the change of control occurred on June 30, 2018, and the Company did not exercise its right to redeem the Preferred Stock, using the closing price of $10.74 as the value of a share of common stock, each share of Preferred Stock would be convertible into approximately 4.7 shares of common stock. If the Company exercises its redemption rights relating to shares of Preferred Stock, the holders of Preferred Stock will not have the conversion right described above.

Note 11 - Other

Operating leases

As of June 30, 2018 the Company had contracts for five horizontal drilling rigs. The contract terms, as amended effective as of July 9, 2018, will end on various dates between July 2019 and February 2021. All of the drilling rig contracts provide for early termination, with penalties calculated at a reduced daily rate. In the event that Callon terminated all five drilling contracts as of August 6, 2018, the Company would owe a maximum of $31,342 over the remaining terms of the respective contracts, offset by any revenues earned for replacement work subsequently secured by the contractor. Management does not currently anticipate the early termination of any drilling rig contracts.

Other commitments

In March 2018, the Company entered into a contract for dedicated fracturing and pump down perforating crews, which was effective on April 16, 2018. The term of the agreement is for two years from the effective date.

Subsequent Event

Callon Petroleum Operating Company executed a firm transportation agreement for dedicated capacity on a new pipeline system that will connect with a regional gathering system which currently transports oil volumes under long-term agreements from our properties in Howard, Ward, Reagan and Upton counties to multiple marketing points in the Permian Basin. Subject to completion of the new pipeline system, which will have delivery points in several locations along the Gulf Coast, we will have a long-term 15,000 Bbls per day commitment.

Satisfaction of the volume commitments includes volumes produced by us and other third-party working, royalty, and overriding royalty interest owners whose volumes we market on their behalf.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

The following management’s discussion and analysis describes the principal factors affecting the Company’s results of operations, liquidity, capital resources and contractual cash obligations. This discussion should be read in conjunction with the accompanying unaudited consolidated financial statements and our 2017 Annual Report on Form 10-K, which include additional information about our business practices, significant accounting policies, risk factors, and the transactions that underlie our financial results. Our website address is www.callon.com. All of our filings with the SEC are available free of charge through our website as soon as reasonably practicable after we file them with, or furnish them to, the SEC. Information on our website does not form part of this report on Form 10-Q.

We are an independent oil and natural gas company established in 1950, focused on the acquisition, development, exploration and exploitation of unconventional, onshore, oil and natural gas reserves in the Permian Basin. The Permian Basin is located in West Texas and southeastern New Mexico and is comprised of three primary sub-basins: the Midland Basin, the Delaware Basin, and the Central Basin Platform. We have historically been focused on the Midland Basin and more recently entered the Delaware Basin through an acquisition completed in February 2017. Our operating culture is centered on responsible development of hydrocarbon resources, with a particular focus on safety and the environment, which we believe strengthens our operational performance. Our operational performance is enhanced by the empowerment of our employees. Our drilling activity is predominantly focused on the horizontal development of several prospective intervals, including multiple levels of the Wolfcamp formation and the Lower Spraberry shales. We have assembled a multi-year inventory of potential horizontal well locations and intend to add to this inventory through delineation drilling of emerging zones on our existing acreage and acquisition of additional locations through working interest acquisitions, leasing programs, acreage purchases, joint ventures and asset swaps. Our production was approximately 77% oil and 23% natural gas for the six months ended June 30, 2018. On June 30, 2018, our net acreage position in the Permian Basin was approximately 53,745 net acres.

Acquisition Highlights

On May 23, 2018, the Company entered into a definitive purchase and sale agreement with Cimarex Energy Company for the acquisition of approximately 47,538 gross (28,657 net) acres in the Spur operating area, located in the Delaware Basin, for an aggregate cash purchase price of $570 million, subject to customary purchase price adjustments (the “Cimarex Acquisition”). In connection with the execution of the purchase and sale agreement, the Company paid a deposit in the amount of $28.5 million, which was recorded as Acquisition deposit on the balance sheet as of June 30, 2018. The Company issued debt and equity to partially fund the Cimarex Acquisition. See Notes 3, 5, and 10 in the Footnotes to the Financial Statements for additional information regarding the Company’s acquisitions, debt obligations, and equity offerings.

Operational Highlights

All of our producing properties are located in the Permian Basin. As a result of our acquisitions and horizontal development efforts, our production grew 30% for the three and six months ended June 30, 2018, compared to the same periods of 2017. Production increased to 2,635 MBOE for the three months ended June 30, 2018 from 2,021 MBOE for the three months ended June 30, 2017 and increased to 5,026 MBOE for the six months ended June 30, 2018 from 3,860 MBOE for the six months ended June 30, 2017.

For the three months ended June 30, 2018, we drilled 18 gross (13.7 net) horizontal wells and completed 19 gross (17.3 net) horizontal wells. For the six months ended June 30, 2018, we drilled 34 gross (27.0 net) horizontal wells and completed 27 gross (21.7 net) horizontal wells. As of June 30, 2018, we had 11 gross (7.2 net) horizontal wells awaiting completion.

As of June 30, 2018, we had 563 gross (450.3 net) working interest oil wells, three gross (0.1 net) royalty interest oil wells and no natural gas wells. A well is categorized as an oil well or a natural gas well based upon the ratio of oil to natural gas reserves on a BOE basis. However, most of our wells produce both oil and natural gas.

Liquidity and Capital Resources

Historically, our primary sources of capital have been cash flows from operations, borrowings from financial institutions, the sale of debt and equity securities, and non-core asset dispositions. Our primary uses of capital have been for the acquisition, development, exploration and exploitation of oil and natural gas properties, in addition to refinancing of debt instruments. We continue to evaluate other sources of capital to complement our cash flow from operations and as we pursue our long-term growth plans.

As of June 30, 2018, we had no principal outstanding on our Credit Facility, which had a borrowing base of $825 million with an elected commitment of $650 million. For the six months ended June 30, 2018, cash and cash equivalents increased $370.0 million to $509.1 million compared to $139.1 million at June 30, 2017.

Operating activities. For the six months ended June 30, 2018, net cash provided by operating activities was $200.0 million compared to net cash provided by operating activities of $95.8 million for the same period in 2017. The change was predominantly attributable to the following:

• An increase in revenue;

• A decrease on settlements of derivative contracts;

• An increase in certain operating expenses related to acquired properties;  

• An decrease in payments in cash-settled restricted stock unit (“RSU”) awards; and

• A change related to the timing of working capital payments and receipts.

Investing activities. For the six months ended June 30, 2018, net cash used in investing activities was $368.3 million compared to $806.4 million for the same period in 2017. The change was predominantly attributable to the following:

• A $137.8 million increase in operational expenditures due to the transition from a three-rig program in the second quarter 2017 to a five-rig program commencing February 2018; and

• A $590.4 million decrease in acquisition activity, net of proceeds from sale of assets. In addition, there was a $28.5 million security deposit in relation to the Cimarex Acquisition. See Note 3 in the Footnotes to the Financial Statements for additional information on the Company’s acquisitions.

Our investing activities, on a cash basis, include the following for the periods indicated (in thousands):

Total investing activities	$	368,285		$	806,441		$	(438,156	)

(a) On an accrual (GAAP) basis, which is the methodology used for establishing our annual capital budget, operational expenditures for the six months ended June 30, 2018 were $271.3 million. Inclusive of seismic, leasehold and other, capitalized general and administrative, and capitalized interest costs, total capital expenditures for the six months ended June 30, 2018 were $316.0 million.

General and administrative expenses and capitalized interest are discussed below in Results of Operations. See Note 3 in the Footnotes to the Financial Statements for additional information on acquisitions.

Financing activities. We finance a portion of our working capital requirements, capital expenditures and acquisitions with borrowings under our Credit Facility, term debt and equity offerings. For the six months ended June 30, 2018, net cash provided by financing activities was $649.5 million compared to net cash provided by financing activities of $196.8 million for the same period of 2017. The change was predominantly attributable to the following:

21

Callon Petroleum Company Management’s Discussion and Analysis of Financial Condition and Results Table of Contents

• An increase in proceeds from a common stock offering in 2018 that raised $288.4 million as compared to no offerings in 2017;

• A $200 million increase in in net borrowings on fixed-rate debt, resulting from the issuances of $400 million of 6.375% Senior Notes in 2018 as compared to $200 million of 6.125% Senior Notes in 2017; and

• A $25.0 million decrease in net borrowings on our Credit Facility in 2018.

See Notes 5 and 10 in the Footnotes to the Financial Statements for additional information on our debt and equity transactions.

Capital Plan and Year to Date 2018 Summary

Our operational capital budget for 2018 was established in the range of $500 to $540 million on an accrual, or GAAP, basis, inclusive of a transition from a four-rig program that commenced in July 2017 to a five-rig program by mid-February 2018. The pending Cimarex Acquisition was not included in the 2018 capital budget. See Note 3 in the Footnotes to the Financial Statements for additional information on acquisitions.

Operational capital expenditures on an accrual basis were $271.3 million for the six months ended June 30, 2018. In addition to the operational capital expenditures, $11.5 million of seismic, leasehold and other, $11.1 million of capitalized general and administrative and $22.1 million of capitalized interest expenses were accrued in the six months ended June 30, 2018. As of June 30, 2018, we have placed 30 gross (22.7 net) horizontal wells on production.

Our revenues, earnings, liquidity and ability to grow are substantially dependent on the prices we receive for, and our ability to develop our reserves of oil and natural gas. We believe the long-term outlook for our business is favorable due to our resource base, low cost structure, financial strength, risk management, including commodity hedging strategy, and disciplined investment of capital. We monitor current and expected market conditions, including the commodity price environment, and our liquidity needs and may adjust our capital investment plan accordingly.

Commodityprices

The prices for oil and natural gas remain extremely volatile and sometimes experience large fluctuations as a result of relatively small changes in supply, weather conditions, economic conditions and actions by the Organization of Petroleum Exporting Countries and other countries and government actions. Prices of oil and natural gas will affect the following aspects of our business:

• our revenues, cash flows and earnings;

• the amount of oil and natural gas that we are economically able to produce;

• our ability to attract capital to finance our operations and cost of the capital;

• the amount we are allowed to borrow under our Credit Facility; and

• the value of our oil and natural gas properties.

For the three and six months ended June 30, 2018, the average NYMEX price for a barrel of oil was $67.91 and $65.43 per Bbl compared to $48.15 and $49.95 per Bbl for the same period of 2017. The NYMEX price for a barrel of oil for the three and six months ended June 30, 2018 ranged from a low of $62.06 per Bbl to a high of $74.15 per Bbl and a low of $59.19 per Bbl to a high of $74.15 per Bbl, respectively.

For the three and six months ended June 30, 2018, the average NYMEX price for natural gas was $2.83 and $2.84 per MMBtu compared to $3.14 and $3.10 per MMBtu for the same periods of 2017. The NYMEX price for natural gas for the three and six months ended June 30, 2018 ranged from a low of $2.66 per MMBtu to a high of $3.02 per MMBtu and a low of $2.55 per MMBtu to a high of $3.63 per MMBtu, respectively.

Oil revenue 

For the three months ended June 30, 2018, oil revenues of $122.6 millionincreased$49.7 million, or 68%, compared to revenues of $72.9 million for the same period of 2017. The increase in oil revenue was primarily attributable to a 25%increase in production and a 35%increase in the average realized sales price, which rose to $61.46 per Bbl from $45.67 per Bbl. The increase in production was comprised of 1,045 MBbls attributable to wells placed on production as a result of our horizontal drilling program and 33 MBbls from producing wells added from our acquired properties. Offsetting these increases were normal and expected declines from our existing wells.

For the six months ended June 30, 2018, oil revenues of $237.9 millionincreased$93.0 million, or 64%, compared to revenues of $144.9 million for the same period of 2017. The increase in oil revenue was primarily attributable to a 27%increase in production and a 29%increase in the average realized sales price, which rose to $61.86 per Bbl from $47.82 per Bbl. The increase in production was comprised of 1,903 MBbls attributable to wells placed on production as a result of our horizontal drilling program and 43 MBbls from producing wells added from our acquired properties. Offsetting these increases were normal and expected declines from our existing wells.

Natural gas revenue (including NGLs)

For the three months ended June 30, 2018, natural gas revenues of $14.5 million increased $5.1 million, or 54%, compared to $9.4 million for the same period of 2017. The increase primarily relates to a 51% increase in natural gas volumes and a 2% increase in the average realized sales price, which rose to $3.77 per Mcf from $3.69 per Mcf, reflecting both natural gas and natural gas liquids prices. The increase in production was comprised of 241 MMcf attributable to wells placed on production as a result of our horizontal drilling program and 68 MMcf from producing wells added from our acquired properties. Offsetting these increases were normal and expected declines from our existing wells. Natural gas revenues for the three months ended June 30, 2018, include a reduction of $2.0 million of gathering and treating expense.

For the six months ended June 30, 2018, natural gas revenues of $26.6 million increased $7.9 million, or 42%, compared to $18.8 million for the same period of 2017. The increase primarily relates to a 42% increase in natural gas volumes. The increase in production was comprised of 395 MMcf attributable to wells placed on production as a result of our horizontal drilling program and 93 MMcf from producing wells added from our acquired properties. The average realized sales price of $3.76 per Mcf, reflecting both natural gas and natural gas liquids prices, was consistent with prices for the same period of 2017. Offsetting these increases were normal and expected declines from our existing wells. Natural gas revenues for the six months ended June 30, 2018, include a reduction of $3.2 million of gathering and treating expense.

See Notes 1, 2 and 3 in the Footnotes to the Financial Statements for additional information regarding revenue recognition and the treatment of gathering and treating expense and the Company’s acquisitions, respectively.

(a) On January 1, 2018, the Company adopted the revenue recognition accounting standard. Consequently, natural gas gathering and treating expenses for the three and six months ended June 30, 2018 were accounted for as a reduction to revenue. See Notes 1 and 2 in the Footnotes to the Financial Statements for additional information regarding revenue recognition and the treatment of gathering and treating expense.

Lease operating expenses (“LOE”). These are daily costs incurred to extract oil and natural gas and maintain our producing properties. Such costs also include maintenance, repairs, salt water disposal, insurance and workover expenses related to our oil and natural gas properties. 

For the three months ended June 30, 2018, LOE increased by 8% to $13.1 million compared to $12.1 million for the same period of 2017. For the three months ended June 30, 2018, LOE per BOE decreased to $4.99 per BOE, excluding gathering and treating expense, compared to $6.01 per BOE, including $0.45 per BOE of gathering and treating expense, for the same period of 2017, which was primarily attributable to higher production volumes from an increased number of producing wells from our horizontal drilling program and acquisitions as discussed above. See Notes 1 and 2 in the Footnotes to the Financial Statements for additional information regarding revenue recognition and the treatment of gathering and treating expense.

26

Callon Petroleum Company Management’s Discussion and Analysis of Financial Condition and Results Table of Contents

For the six months ended June 30, 2018, LOE increased by 4% to $26.2 million compared to $25.1 million for the same period of 2017. For the six months ended June 30, 2018, LOE per BOE decreased to $5.21 per BOE, excluding gathering and treating expense, compared to $6.50 per BOE, including $0.44 per BOE of gathering and treating expense, for the same period of 2017, which was primarily attributable to higher production volumes from an increased number of producing wells from our horizontal drilling program and acquisitions as discussed above. See Notes 1 and 2 in the Footnotes to the Financial Statements for additional information regarding revenue recognition and the treatment of gathering and treating expense.

Production taxes. Production taxes include severance and ad valorem taxes. In general, production taxes are directly related to commodity price changes; however, severance taxes are based upon current year commodity prices, whereas ad valorem taxes are based upon prior year commodity prices. Severance taxes are paid on produced oil and natural gas based on a percentage of revenues from products sold at fixed rates established by federal, state or local taxing authorities. Where available, we benefit from tax credits and exemptions in our various taxing jurisdictions. In the counties where our production is located, we are also subject to ad valorem taxes, which are generally based on the taxing jurisdictions’ valuation of our oil and gas properties. 

Production taxes for the three months ended June 30, 2018increased by 56% to $7.5 million compared to $4.8 million for the same period of 2017. The increase was primarily due to an increase in severance taxes, which was attributable to the increase in revenue. On a per BOE basis, production taxes for the three months ended June 30, 2018increased by 20% compared to the same period of 2017.

Production taxes for the six months ended June 30, 2018increased by 49% to $16.0 million compared to $10.7 million for the same period of 2017. The increase was primarily due to an increase in severance taxes, which was attributable to the increase in revenue. Also contributing to the increase was an increase in ad valorem taxes, which was attributable to an increase in the valuation of our oil and gas properties by taxing jurisdictions as a result of an increased number of producing wells from our horizontal drilling program, and acquisitions as discussed above. On a per BOE basis, production taxes for the six months ended June 30, 2018increased by 14% compared to the same period of 2017.

Depreciation, depletion and amortization (“DD&A”). Under the full cost accounting method, we capitalize costs within a cost center and then systematically expense those costs on a units-of-production basis based on proved oil and natural gas reserve quantities. We calculate depletion on the following types of costs: (i) all capitalized costs, other than the cost of investments in unevaluated properties, less accumulated amortization; (ii) the estimated future expenditures to be incurred in developing proved reserves; and (iii) the estimated dismantlement and abandonment costs, net of estimated salvage values. Depreciation of other property and equipment is computed using the straight line method over their estimated useful lives, which range from three to fifteen years.

For the three months ended June 30, 2018, DD&A increased48% to $38.7 million compared to $26.2 million for the same period of 2017. The increase is primarily attributable to a 30%increase in production and a 13% increase in our per BOE DD&A rate. For the three months ended June 30, 2018, DD&A on a per unit basis increased to $14.70 per BOE compared to $12.97 per BOE for the same period of 2017. The increase is attributable to greater increases in our depreciable base and assumed future development costs to undeveloped proved reserves relative to the increase in our estimated proved reserve base. The increases in our depreciable base, assumed future development costs and estimated proved reserve base are a result of additions made through our horizontal drilling efforts and acquisitions.

For the six months ended June 30, 2018, DD&A increased46% to $74.2 million compared to $50.6 million for the same period of 2017. The increase is primarily attributable to a 30%increase in production and a 12% increase in our per BOE DD&A rate. For the six months ended June 30, 2018, DD&A on a per unit basis increased to $14.75 per BOE compared to $13.12 per BOE for the same period of 2017. The increase is attributable to greater increases in our depreciable base and assumed future development costs to undeveloped proved reserves relative to the increase in our estimated proved reserve base. The increases in our depreciable base, assumed future development costs and estimated proved reserve base are a result of additions made through our horizontal drilling efforts and acquisitions.

General and administrative, net of amounts capitalized (“G&A”). These are costs incurred for overhead, including payroll and benefits for our corporate staff, severance and early retirement expenses, costs of maintaining offices, managing our production and development operations, franchise taxes, depreciation of corporate level assets, public company costs, vesting of equity and liability awards under share-based compensation plans and related mark-to-market valuation adjustments over time, fees for audit and other professional services, and legal compliance.

Settled share-based awards. In June 2017, the Company settled the outstanding share-based award agreements of its former Chief Executive Officer, resulting in $6.4 million recorded on the Consolidated Statements of Operations as Settled share-based awards.

Accretion expense. The Company is required to record the estimated fair value of liabilities for obligations associated with the retirement of tangible long-lived assets and the associated ARO costs. Interest is accreted on the present value of the ARO and reported as accretion expense within operating expenses in the consolidated statements of operations.

Accretion expense related to our ARO for the three months ended June 30, 2018, was consistent with the same period of 2017. Accretion expense related to our ARO for the six months ended June 30, 2018, increased8% compared to the same period of 2017. Accretion expense generally correlates with the Company’s ARO, which was $10.1 million at June 30, 2018 as compared to $6.8 million at June 30, 2017. See Note 9 in the Footnotes to the Financial Statements for additional information regarding the Company’s ARO.

Acquisition expense. Acquisition expense decreased$0.6 million and $0.5 million for the three and six months ended June 30, 2018, compared to the same periods of 2017. Acquisition expense for all periods was related to costs with respect to our acquisition efforts in the Permian Basin. See Note 3 in the Footnotes to the Financial Statements for additional information regarding the Company’s acquisitions.

໿Interest expense, net of capitalized amounts. We finance a portion of our working capital requirements, capital expenditures and acquisitions with borrowings under our Credit Facility or with term debt. We incur interest expense that is affected by both fluctuations in interest rates and our financing decisions. We reflect interest paid to our lender in interest expense, net of capitalized amounts. In addition, we include the amortization of deferred financing costs (including origination and amendment fees), commitment fees and annual agency fees in interest expense.

Interest expense, net of capitalized amounts, of $0.6 million incurred during the three months ended June 30, 2018 was consistent with the same period of 2017. Interest expense, net of capitalized amounts, incurred during the six months ended June 30, 2018decreased$0.2 million compared to the same period of 2017. This decrease was primarily due to an increase in the premium amortization of $0.5 million attributable to the 6.125% Senior Notes. Offsetting the decrease was a $0.3 million increase in deferred financing costs primarily resulting from the issuance of $400 million of 6.375% Senior Notes. See Note 5 in the Footnotes to the Financial Statements for additional information on our debt obligations.

Gain (loss) on derivative instruments. We utilize commodity derivative financial instruments to reduce our exposure to fluctuations in commodity prices. This amount represents the (i) gain (loss) related to fair value adjustments on our open derivative contracts and (ii) gains (losses) on settlements of derivative contracts for positions that have settled within the period.

For the three months ended June 30, 2018, the net loss on derivative contracts was $16.6 million compared to a $10.5 million net gain for the same period of 2017. The net gain (loss) on derivative instruments for the periods indicated includes the following (in thousands):

See Notes 6 and 7 in the Footnotes to the Financial Statements for additional information on the Company’s derivative contracts and disclosures related to derivative instruments.

Income tax expense.We use the asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax consequences of (1) temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities and (2) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period when those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the rate change is enacted. When appropriate, based on our analysis, we record a valuation allowance for deferred tax assets when it is more likely than not that the deferred tax assets will not be realized.

The Company had income tax expenseof $0.5 million and $1.0 million for the three and six months ended June 30, 2018, compared to income tax expense of $0.3 million and $0.8 million for the same periods of 2017. The change in income tax expense is primarily related to deferred state of Texas gross margin tax. The Company had a valuation allowance of $38.6 million as of June 30, 2018. See Note 8 in the Footnotes to the Financial Statements for additional information.

Preferred Stock dividends. Preferred Stock dividends of $1.8 million and $3.6 million for the three and six months ended June 30, 2018 were consistent with dividends for the same periods of 2017. Dividends reflect a 10% dividend rate. See Note 10 in the Footnotes to the Financial Statements for additional information.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to a variety of market risks including commodity price risk, interest rate risk and counterparty and customer risk. We mitigate these risks through a program of risk management including the use of derivative instruments.

Commodity price risk

The Company’s revenues are derived from the sale of its oil and natural gas production. The prices for oil and natural gas remain volatile and sometimes experience large fluctuations as a result of relatively small changes in supply, demand, regional market conditions, weather conditions, economic conditions and government actions. From time to time, the Company enters into derivative financial instruments to manage oil and natural gas price risk, related both to NYMEX benchmark prices and regional basis differentials. The total volumes which we hedge through use of our derivative instruments varies from period to period; however, generally our objective is to hedge approximately 40% to 60% of our anticipated internally forecast production, subject to market conditions, for the next 12 to 24 months, subject to the covenants under our Credit Facility. Our hedge policies and objectives may change significantly with movements in commodities prices or futures prices, in addition to modification of our capital spending plans related to operational activities and acquisitions.

The Company’s hedging portfolio, linked to NYMEX benchmark pricing, covers approximately 3,588,000 Bbls and 3,864,000 MMBtu of our expected oil and natural gas production, respectively, for the remainder of 2018. We also have commodity hedging contracts linked to Midland WTI basis differentials relative to Cushing and Waha basis differentials covering approximately 2,208,000 Bbls and 1,104,000 MMBtu of our expected oil and natural gas production, respectively, for the remainder of 2018. See Note 6 in the Footnotes to the Financial Statements for a description of the Company’s outstanding derivative contracts at June 30, 2018, and derivative contracts established subsequent to that date.

The Company may utilize fixed price swaps, which reduce the Company’s exposure to decreases in commodity prices and limit the benefit the Company might otherwise have received from any increases in commodity prices. Swap contracts may also be enhanced by the simultaneous sale of call or put options to effectively increase the effective swap price as a result of the receipt of premiums from the option sales.

The Company may utilize price collars to reduce the risk of changes in oil and natural gas prices. Under these arrangements, no payments are due by either party as long as the applicable market price is above the floor price (purchased put option) and below the ceiling price (sold call option) set in the collar. If the price falls below the floor, the counter-party to the collar pays the difference to the Company, and if the price rises above the ceiling, the counterparty receives the difference from the Company. Additionally, the Company may sell put (or call) options at a price lower than the floor price (or higher than the ceiling price) in conjunction with a collar (three-way collar) and use the proceeds to increase either or both the floor or ceiling prices. In a three-way collar, to the extent that realized prices are below the floor price of the sold put option (or above the ceiling price of the sold call option), the Company’s net realized benefit from the three-way collar will be reduced on a dollar-for-dollar basis.

The Company may purchase put and call options, which reduce the Company’s exposure to decreases in oil and natural gas prices while allowing realization of the full benefit from any increases in oil and natural gas prices. If the price falls below the floor, the counterparty pays the difference to the Company.

The Company enters into these various agreements to reduce the effects of volatile oil and natural gas prices and does not enter into derivative transactions for speculative purposes. Presently, none of the Company’s derivative positions are designated as hedges for accounting purposes.

Interest rate risk

The Company is subject to market risk exposure related to changes in interest rates on our indebtedness under our Credit Facility. As of June 30, 2018, the Company had no principal outstanding under the Credit Facility with a weighted average interest rate of 3.97%. Based on a notional amount of $10 million outstanding under the facility, an increase or decrease of 1.00% in the interest rate would have a corresponding increase or decrease in our annual net income of approximately $0.1 million. See Note 5 in the Footnotes to the Financial Statements for more information on the Company’s interest rates on its Credit Facility.

Counterparty and customer credit risk

The Company’s principal exposures to credit risk are through receivables from the sale of our oil and natural gas production, joint interest receivables and receivables resulting from derivative financial contracts.

31

Callon Petroleum Company Table of Contents

The Company markets its oil and natural gas production to energy marketing companies. We are subject to credit risk due to the concentration of our oil and natural gas receivables with several significant customers. The inability of our significant customers to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results. At June 30, 2018 our total receivables from the sale of our oil and natural gas production were approximately $73.4 million.

Joint interest receivables arise from billings to entities that own partial interests in the wells we operate. These entities participate in our wells primarily based on their ownership in leases on which we have or intend to drill. We have little ability to control whether these entities will participate in our wells. At June 30, 2018 our joint interest receivables were approximately $35.7 million.

Our oil and natural gas derivative arrangements expose us to credit risk in the event of nonperformance by counterparties. Most of the counterparties on our derivative instruments currently in place are lenders under our Credit Facility. We are likely to enter into additional derivative instruments with these or other lenders under our Credit Facility, representing institutions with investment grade ratings. We have existing International Swap Dealers Association Master Agreements (“ISDA Agreements”) with our derivative counterparties. The terms of the ISDA Agreements provide us and the counterparties with rights of offset upon the occurrence of defined acts of default by either us or a counterparty to a derivative, whereby the party not in default may offset all derivative liabilities owed to the defaulting party against all derivative asset receivables from the defaulting party.  

Item 4. Controls and Procedures

Disclosure controls and procedures. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is accumulated and communicated to the issuer’s management, including its principal executive and financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our Chief Executive Officer and Chief Financial Officer performed an evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our principal executive and principal financial officers have concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2018.

Changes in internal control over financial reporting. There were no changes to our internal control over financial reporting during our last fiscal quarter that have materially affected, or are reasonable likely to materially affect, our internal control over financial reporting.

Part II.  Other Information

Item 1.  Legal Proceedings

We are a defendant in various legal proceedings and claims, which arise in the ordinary course of our business. We do not believe the ultimate resolution of any such actions will have a material effect on our financial position or results of operations.

Item 1A. Risk Factors

In addition to the information set forth in this Quarterly Report, you should carefully consider the risks discussed in our Annual Report on Form 10-K for the year ended December 31, 2017. The risks described in our Annual Report on Form 10-K for the year ended December 31, 2017, and in this Quarterly Report are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

The purchase agreement for the Cimarex Acquisition contains conditions to closing, some of which are beyond our control, and we may be unable to consummate the Cimarex Acquisition. The purchase agreement for the Cimarex Acquisition contains closing conditions, including limitations on purchase price adjustments (including with respect to adjustments for title and environmental defects) and customary closing conditions. It is possible that one or more of the conditions in the purchase agreement will not be satisfied, and we may be unable or unwilling to consummate the Cimarex Acquisition. If the Cimarex Acquisition is not closed on account of a material breach of the purchase agreement on our part that is not subsequently cured, we may be required to forfeit our earnest money deposit as liquidated damages. If we are unable to close the Cimarex Acquisition, our common stock price could be materially adversely affected.

Our analysis of the properties subject to the Cimarex Acquisitionwas based in part on information provided to us by the seller and the limited representations, warranties and indemnifications of the seller contained in the purchase agreement, which may prove to be incorrect, resulting in our not realizing the expected benefits of this transaction and the value of the transaction is largely associated with undeveloped acreage that may not materialize. Our analysis of the properties subject to the Cimarex Acquisition, including our estimates of the associated proved reserves, is based in part on information provided to us by the seller, including historical production data. Our independent reserve engineers have not provided a report regarding the estimates of reserves with respect to the properties subject to this transaction. As a result, the assumptions on which our internal estimates of proved reserves and horizontal drilling locations have been based may prove to be incorrect in a number of material ways, resulting in our not realizing our expected benefits of this transaction. In addition, the representations, warranties and indemnities of the seller contained in the purchase agreement are limited, and we may not have recourse against the seller in the event that the acreage does not perform as expected.

Furthermore, a large portion of the acreage we are acquiring is undeveloped, and our plans, development schedule and production schedule associated with the acreage may fail to materialize. As a result, our investment in these areas may not be as economic as we anticipate, and we could incur material write-downs of unevaluated properties.

The Cimarex Acquisition involves risks associated with acquisitions and integrating acquired properties, including the potential exposure to significant liabilities, and the intended benefits of the Cimarex Acquisition may not be realized. The Cimarex Acquisition involves risks associated with acquisitions and integrating acquired properties into existing operations, including that:

• our senior management’s attention may be diverted from the management of daily operations to the integration of the assets acquired in the Cimarex Acquisition and our recent acquisitions;

• we could incur significant unknown and contingent liabilities for which we have limited or no contractual remedies or insurance coverage;

• the properties acquired in the Cimarex Acquisition may not perform as well as we anticipate;

• unexpected costs, delays and challenges may arise in integrating the assets acquired in the Cimarex Acquisition into our existing operations; and

• we may need to hire additional staff and devote additional resources to integrate the properties acquired in the Cimarex Acquisition.

Even if we successfully integrate the properties acquired in the Cimarex Acquisition into our operations, it may not be possible to realize the full benefits we anticipate or we may not realize these benefits within the expected timeframe. If we fail to realize the benefits we anticipate from the Cimarex Acquisition, our business, results of operations and financial condition may be materially adversely affected.

5.Restrictions Imposed by Law.

- 2 -

limitation, dividend and voting rights) with respect to any such shares of Common Stock, unless and until and after such shares of Common Stock have been delivered to the Grantee as described in Section 2.

Dividend Equivalents shall be subject to the same vesting schedule as the underlying Restricted Stock Units and shall be payable in cash at the same time as the Restricted Stock Units are settled pursuant to Section 2.

5.Mandatory Withholding ofTaxes. Grantee acknowledges and agrees that the Company shall deduct from the shares of Common Stock otherwise deliverable a number of shares of Common Stock (valued at their Fair Market Value) on the applicable date that is equal to the amount of all federal, state and local taxes required to be withheld by the Company. In the event the Company, in its sole discretion, determines that the Grantee’s tax obligations will not be satisfied under the method otherwise expressly described above and the Grantee does not provide payment to the Company in the form of shares of Common Stock (valued at their Fair Market Value) sufficient to satisfy any withholding obligations, then the Grantee, subject to compliance with the Company’s insider trading policies, authorizes the Company or the Company’s Stock Plan Administrator, currently Fidelity, to (i) sell a number of shares of Common Stock issued or outstanding pursuant to the Award, which number of shares of Common Stock the Company determines has at least the market value sufficient to meet the tax withholding obligations, plus additional shares of Common Stock to account for rounding and market fluctuations and (ii) pay such tax withholding to the Company. The Grantee may elect to have the Company withhold or purchase, as applicable, from shares of Common Stock or cash that would otherwise payable or deliverable an amount of cash and/or number of shares of Common Stock (valued at their Fair Market Value) equal to the product of the maximum federal marginal rate that could be applicable to the Grantee and the Fair Market Value of the shares of Common Stock or cash otherwise payable or deliverable, as applicable.

6.Restrictions Imposed by Law. Without limiting the generality of Section 16 of the Plan, the Grantee agrees that the Company will not be obligated to deliver any shares of Common Stock if counsel to the Company determines that such delivery would violate any applicable law or any rule or regulation of any governmental authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which the Common Stock is listed or quoted. The Company shall in no event be obligated to take any affirmative action in order to cause the issuance or delivery of shares of Common Stock to comply with any such law, rule, regulation or agreement.

Restricted Stock Units under this Agreement are designed to be exempt from or comply with Section 409A of the Code and the related Treasury Regulations thereunder and the provisions of this Agreement will be administered, interpreted and construed accordingly (or disregarded to the extent such provision cannot be so administered, interpreted, or construed). If the Grantee is identified by the Company as a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i) on the date on which the Grantee has a “separation from service” (other than due to death) within the meaning of Treasury Regulation § 1.409A-1(h), any amount payable or settled under this Agreement on account of a separation from service that is deferred compensation subject to Section 409A of the Code shall be paid or settled on the earliest of (1) the first business day following the expiration of six months from the Grantee’s separation from service, (2) the date of the Grantee’s death, or (3) such earlier date as complies with the requirements of Section 409A of the Code.

12.Excise Taxes. Notwithstanding anything to the contrary in this Agreement, if the Grantee is a “disqualified individual” (as defined in Code Section 280G(c)), and the payments and benefits provided for under this Agreement, together with any other payments and benefits which the Grantee has the right to receive from the Company or any of its affiliates or any party to a transaction with the Company or any of its affiliates, would constitute a “parachute payment” (as defined in Code Section 280G(b)(2)), then the payments and benefits provided for under this Agreement shall be either (a) reduced (but not below zero) so that the present value of such total amounts and benefits received by the Grantee from the Company and its

- 4 -

affiliates will be one dollar ($1.00) less than three times the Grantee’s “base amount” (as defined in Code Section 280G(b)(3)) and so that no portion of such amounts and benefits received by the Grantee shall be subject to the excise tax imposed by Code Section 4999 or (b) paid in full, whichever produces the better net after-tax position to the Grantee (taking into account any applicable excise tax under Code Section 4999 and any other applicable taxes). The reduction of payments and benefits hereunder, if applicable, shall be made by reducing payments or benefits to be paid hereunder in the order in which such payment or benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time). The determination as to whether any such reduction in the amount of the payments and benefits provided hereunder is necessary shall be made by a nationally recognized accounting firm selected by the Company. If a reduced payment or benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its affiliates) used in determining if a parachute payment exists, exceeds one dollar ($1.00) less than three times the Grantee’s base amount, then the Grantee shall immediately repay such excess to the Company upon notification that an overpayment has been made.

13.Grantee Acceptance. The Grantee shall accept the terms and conditions of this Agreement through the online acceptance procedures set forth by the Company’s Stock Plan Administrator.

CALLON PETROLEUM COMPANY

2018 OMNIBUS INCENTIVE PLAN

THIS AGREEMENT (“Agreement”) is effective as of ______________,______ (the “Grant Date”), by and between Callon Petroleum Company, a Delaware corporation (the “Company”), and ____________________ (the “Grantee”).

The Company has adopted the Callon Petroleum Company 2018 Omnibus Incentive Plan, as effective May 10, 2018 (as may be amended from time to time, the “Plan”), which by this reference is made a part hereof, for the benefit of eligible employees, directors and independent contractors of the Company and its Subsidiaries. Capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Plan.

Pursuant to the Plan, the Committee, which has generally been assigned responsibility for administering the Plan, has determined that it would be in the interest of the Company and its stockholders to grant the performance shares provided herein in order to provide Grantee with additional remuneration for services rendered, to encourage Grantee to remain in the employ of the Company or its Subsidiaries and to increase Grantee’s personal interest in the continued success and progress of the Company.

The Company and Grantee therefore agree as follows:

1.Grant of Performance Shares.Pursuant to the Plan and subject further to the terms and conditions herein, the Company and Grantee enter into this Agreement pursuant to which the Grantee has a target of __________ performance shares (the “Target Award”) where each performance share represents the right to receive the cash equivalent of the Fair Market Value of one share of Common Stock (“Performance Shares”). The range of Performance Shares which may be earned by the Grantee is 0 to 200% of the Target Award. The Performance Shares that will vest, if at all, are the Adjusted Performance Shares determined based on the performance metrics set forth in Exhibit A to this Agreement; provided that, subject to the provisions of Section 4, the Grantee remains in continuous employment with the Company through the last day of the Performance Period (as defined below). For purposes of this Agreement, references to employment with the Company include employment with any successor to the Company as well as employment with any Subsidiary.

3.Payment of Performance Shares. Upon vesting of the Adjusted Performance Shares in accordance with Exhibit A or Section 4, the Adjusted Performance Shares shall be settled in cash, in each case subject to Section 6. For those Adjusted Performance Shares settleable in cash, the Grantee shall be entitled to receive a cash lump sum payment in an amount that is equal to (i) the Fair Market Value of the Common Stock on the Vesting Date multiplied by (ii) the Adjusted Performance Shares. The payment shall be made or shares of Common Stock delivered within forty-five (45) calendar days from the Vesting Date.

Upon termination of the Grantee’s employment with the Company as a result of the death or Disability of the Grantee, the Performance Shares shall immediately vest, with the number of Adjusted Performance Shares determined in accordance with Exhibit A, as if the date of such termination of employment was the last day of the Performance Period. For purposes hereof, “Disability” shall mean the physical or mental inability of Grantee to carry out the normal and usual duties of his position on a full-time basis for an entire period of six (6) continuous months together with the reasonable likelihood, as determined by the Committee, that Grantee, upon the advice of a qualified physician, will be unable to carry out the normal and usual duties of his position.

For purposes hereof, “Cause” is defined as: (i) the conviction of the Grantee by a court of competent jurisdiction as to which no further appeal can be taken of a crime involving moral turpitude or a felony or entering the plea of nolo contendere to such crime by the Grantee; (ii) the commission by the Grantee of a material act of fraud upon the Company, any Subsidiary or Affiliate; (iii) the material misappropriation by the Grantee of any funds or other property of the Company, any Subsidiary or Affiliate; (iv) the knowing engagement by the Grantee without the written approval of the Board, in any material activity which directly competes with the business of the Company, any Subsidiary or Affiliate, or which would directly result in material injury to the business or reputation of the Company or any Subsidiary or Affiliate; (v)(1) a material breach by the Grantee during the Grantee’s employment with the Company of any of the restrictive covenants set out in the Grantee’s employment agreement with the Company, if applicable, or (2) the willful and material nonperformance of the Grantee’s duties to the Company or any Subsidiary or Affiliate (other than by reason of the Grantee’s illness or incapacity), and, for purposes of this clause (v), no act or failure to act on Grantee’s part shall be deemed “willful” unless it is done or omitted by the Grantee not in good faith and without his reasonable belief that such action or omission was in the best interest of the Company, (vi) any breach of the Grantee’s fiduciary duties to the Company, including, without limitation, the duties of care, loyalty and obedience to the law; and (vii) the intentional failure of the Grantee to comply with the Company's Code of Business Conduct and Ethics, or to otherwise discharge his duties in good faith and in a manner that the Grantee reasonably believes to be in the best interests of the Company, and with the care an ordinarily prudent person in a like position would exercise under similar circumstances.

(c)Termination following a Change in Control. In the event of the Grantee’s termination of employment by the Company for any reason other than Cause within the two-year period immediately following the effective date of a Change in Control, the Performance Shares shall immediately vest, with the number of Adjusted Performance Shares determined in accordance with Exhibit A, as if the date of the Change in Control was the last day of the Performance Period.

5.No Ownership Rights Prior to Issuance of Shares of Common Stock; Dividend Equivalents. Neither the Grantee nor any other person shall become the beneficial owner of the shares of Common Stock underlying the Performance Shares, nor have any rights of a shareholder (including, without limitation, dividend and voting rights) with respect to any such shares of Common Stock. Notwithstanding the foregoing, prior to the vesting of the underlying Performance Shares, Dividend Equivalents shall be accrued on the Target Award, without interest, for the benefit of the Grantee. Dividend Equivalents shall be subject to the same vesting conditions as the underlying Performance Shares and shall be payable in cash at the same time as the Adjusted Performance Shares are settled pursuant to Section 3.

Exhibit A

Calculation of the

Adjusted Performance Shares

Subject to the provisions in the Agreement, effective as of the last day of the Performance Period (the “Vesting Date”), the Company’s “Total Shareholder Return” will be calculated and compared to the same calculated total shareholder return of the selected group of peer companies that are listed below.  As soon as administratively practicable following the Vesting Date, the number of Performance Shares that vest under the Agreement will be determined in accordance with the payout percentage that is based on the Company’s relative ranking with the peer companies as shown in the table below (such number, the “Adjusted Performance Shares”).

For purposes of this calculation, the Company’s total shareholder return and that of the peer companies will be adjusted if necessary for stock splits, and the percentage increase or decrease will be calculated as follows:

(EP + CD) - BP	= % increase or decrease
BP

Ending price (EP) - equals the average closing price of a share of Common Stock during the twenty (20) day trading period ending ______________,______. 

Beginning price (BP) - equals the average closing price of a share of Common Stock during the twenty (20) day trading period ending immediately prior to the Grant Date.

Cash Dividends (CD) - equals the cash dividends paid on a share of Common Stock during the Performance Period.

A similar calculation will also be performed for each peer company.  The resulting percentage for the Company and the peer companies will then be ranked.  Based on the relative ranking, the number of Performance Shares that vest under the Agreement will be determined in accordance with the following table:

Percentile Ranking	Payout as a % of Award
>90th Percentile	200%
50th Percentile	100%
25th Percentile	25%
<25th Percentile	0%

- 1 -

Percentile ranks between the percentiles described above would be interpolated. Based on a peer group of 13 companies (including the Company), this results in a payout schedule as follows:

Rank	Payout (as a % of Award)
1-2	200%
3	183%
4	163%
5	142%
6	121%
7	100%
8	75%
9	50%
10	25%
11-13	0%

If the Total Shareholder Return of the Company is negative, then the maximum number of Adjusted Performance Shares that shall vest shall be the Target Award. In the event that during the Performance Period one or more of the listed peer companies is involved in a merger/acquisition, and (i) such merger/acquisition was announced on or prior to ______________,______, then such named peer company(s) will be replaced with a suitable replacement, as determined in the Committee’s sole discretion or (ii) such merger/acquisition was announced after ______________,______, then such peer company(s) will move to the top or the bottom of the ranking, based on whether said peer company’s Total Shareholder Return is greater or less than that for the Company, in each case measured as of the date of the announcement of such merger/acquisition.  If, during the Performance Period, any peer company declares bankruptcy or initiates (or becomes subject to) a similar proceeding as a debtor due to insolvency, then, for the purposes of ranking the peer companies and the Company, such peer company shall be ranked last.

This Agreement is entered into, and the Award evidenced hereby is granted, pursuant to the Plan and shall be governed by and construed in accordance with the Plan and the administrative interpretations adopted by the Committee thereunder. All decisions of the Committee upon questions regarding the Plan or this Agreement shall be conclusive. Unless otherwise expressly stated herein, in the event of any inconsistency between the terms of the Plan and this Agreement, the terms of the Plan shall control. The headings of the sections of this Agreement have been included for convenience of reference only, are not to be considered a part hereof and shall in no way modify or restrict any of the terms or provisions hereof.

12.Code Section 409A. Performance Shares under this Agreement are designed to be exempt from or comply with Section 409A of the Code and the related Treasury Regulations thereunder and the provisions of this Agreement will be administered, interpreted and construed accordingly (or disregarded to the extent such provision cannot be so administered, interpreted, or construed). If the Grantee is identified by the Company as a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i) on the date on which the Grantee has a “separation from service” (other than due to death) within the meaning of Treasury Regulation § 1.409A-1(h), any amount payable or settled under this Agreement on account of a separation from service that is deferred compensation subject to Section 409A of the Code shall be paid or settled on the earliest of (1) the first business day following the expiration of six months from the Grantee’s separation from service, (2) the date of the Grantee’s death, or (3) such earlier date as complies with the requirements of Section 409A of the Code.

13.Excise Taxes. Notwithstanding anything to the contrary in this Agreement, if the Grantee is a “disqualified individual” (as defined in Code Section 280G(c)), and the payments and benefits provided for under this Agreement, together with any other payments and benefits which the Grantee has the right to receive from the Company or any of its affiliates or any party to a transaction with the Company or any of its affiliates, would constitute a “parachute payment” (as defined in Code Section 280G(b)(2)), then the payments and benefits provided for under this Agreement shall be either (a) reduced (but not below zero) so that the present value of such total amounts and benefits received by the Grantee from the Company and its affiliates will be one dollar ($1.00) less than three times the Grantee’s “base amount” (as defined in Code Section 280G(b)(3)) and so that no portion of such amounts and benefits received by the Grantee shall be subject to the excise tax imposed by Code Section 4999 or (b) paid in full, whichever produces the better net after-tax position to the Grantee (taking into account any applicable excise tax under Code Section 4999 and any other applicable taxes). The reduction of payments and benefits hereunder, if applicable, shall be made by reducing payments or benefits to be paid hereunder in the order in which such payment or benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time). The determination as to whether any such reduction in the amount of the payments and benefits provided hereunder is necessary shall be made by a nationally recognized accounting firm selected by the Company. If a reduced payment or benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its affiliates) used in determining if a parachute payment exists, exceeds one dollar ($1.00) less than three times the Grantee’s base amount, then the Grantee shall immediately repay such excess to the Company upon notification that an overpayment has been made.

14.Grantee Acceptance. The Grantee shall accept the terms and conditions of this Agreement through the online acceptance procedures set forth by the Company’s Stock Plan Administrator. By electronically accepting this Agreement the Grantee acknowledges receipt of a copy of the Plan and hereby accepts this Award subject to all the terms and provisions hereof and thereof.

Exhibit A

Calculation of the

Adjusted Performance Shares

Subject to the provisions in the Agreement, effective as of the last day of the Performance Period (the “Vesting Date”), the Company’s “Total Shareholder Return” will be calculated and compared to the same calculated total shareholder return of the selected group of peer companies that are listed below.  As soon as administratively practicable following the Vesting Date, the number of Performance Shares that vest under the Agreement will be determined in accordance with the payout percentage that is based on the Company’s relative ranking with the peer companies as shown in the table below (such number, the “Adjusted Performance Shares”).

For purposes of this calculation, the Company’s total shareholder return and that of the peer companies will be adjusted if necessary for stock splits, and the percentage increase or decrease will be calculated as follows:

(EP + CD) - BP	= % increase or decrease
BP

Ending price (EP) - equals the average closing price of a share of Common Stock during the twenty (20) day trading period ending ______________,______. 

Beginning price (BP) - equals the average closing price of a share of Common Stock during the twenty (20) day trading period ending immediately prior to the Grant Date.

Cash Dividends (CD) - equals the cash dividends paid on a share of Common Stock during the Performance Period.

A similar calculation will also be performed for each peer company.  The resulting percentage for the Company and the peer companies will then be ranked.  Based on the relative ranking, the number of Performance Shares that vest under the Agreement will be determined in accordance with the following table:

Percentile Ranking	Payout as a % of Award
>90th Percentile	200%
50th Percentile	100%
25th Percentile	25%
<25th Percentile	0%

Percentile ranks between the percentiles described above would be interpolated. Based on a peer group of 13 companies (including the Company), this results in a payout schedule as follows:

Rank	Payout (as a % of Award)
1-2	200%
3	183%
4	163%
5	142%
6	121%
7	100%
8	75%
9	50%
10	25%
11-13	0%

If the Total Shareholder Return of the Company is negative, then the maximum number of Adjusted Performance Shares that shall vest shall be the Target Award. In the event that during the Performance Period one or more of the listed peer companies is involved in a merger/acquisition, and (i) such merger/acquisition was announced on or prior to ______________,______, then such named peer company(s) will be replaced with a suitable replacement, as determined in the Committee’s sole discretion or (ii) such merger/acquisition was announced after ______________,______, then such peer company(s) will move to the top or the bottom of the ranking, based on whether said peer company’s Total Shareholder Return is greater or less than that for the Company, in each case measured as of the date of the announcement of such merger/acquisition.  If, during the Performance Period, any peer company declares bankruptcy or initiates (or becomes subject to) a similar proceeding as a debtor due to insolvency, then, for the purposes of ranking the peer companies and the Company, such peer company shall be ranked last.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business and Basis of Presentation

Description of Business and Basis of Presentation

Description of business

Callon Petroleum Company is an independent oil and natural gas company established in 1950. The Company was incorporated under the laws of the state of Delaware in 1994 and succeeded to the business of a publicly traded limited partnership, a joint venture with a consortium of European investors and an independent energy company. As used herein, the “Company,” “Callon,” “we,” “us,” and “our” refer to Callon Petroleum Company and its predecessors and subsidiaries unless the context requires otherwise.

Callon is focused on the acquisition, development, exploration and exploitation of unconventional onshore, oil and natural gas reserves in the Permian Basin. The Company’s operations to date have been predominantly focused on the horizontal development of several prospective intervals, including multiple levels of the Wolfcamp formation and the Lower Spraberry shales. Callon has assembled a multi-year inventory of potential horizontal well locations and intends to add to this inventory through delineation drilling of emerging zones on its existing acreage and acquisition of additional locations through working interest acquisitions, leasing programs, acreage purchases, joint ventures and asset swaps. 

Basis of presentation

Unless otherwise indicated, all dollar amounts included within the Footnotes to the Financial Statements are presented in thousands, except for per share and per unit data.

The interim consolidated financial statements of the Company have been prepared in accordance with (1) GAAP, (2) the SEC’s instructions to Quarterly Report on Form 10-Q and (3) Rule 10-01 of Regulation S-X, and include the accounts of Callon Petroleum Company, and its subsidiary, Callon Petroleum Operating Company (“CPOC”). CPOC also has subsidiaries, namely Callon Offshore Production, Inc. and Mississippi Marketing, Inc.

These interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The balance sheet at December 31, 2017 has been derived from the audited financial statements at that date. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the year ended December 31, 2018.

In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments, including normal recurring adjustments and all intercompany account and transaction eliminations, necessary to present fairly the Company’s financial position, the results of its operations and its cash flows for the periods indicated. Certain prior year amounts may have been reclassified to conform to current year presentation.

Accounting Standards Updates (“ASUs”)

Recently Adopted ASUs - Revenue Recognition

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 replaced most of the existing revenue recognition requirements in GAAP. The standard can be applied using either the full retrospective approach or a modified retrospective approach at the date of adoption.

Throughout 2015 and 2016, the FASB issued several updates to the revenue recognition guidance in Accounting Standards Codification Topic 606 (“ASC 606”). In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU 2014-09 by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net). Under this update, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing. This update clarifies two principles of ASC 606: identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients. This update applies only to the following areas from ASC 606: assessing the collectability criterion and accounting for contracts that do not meet the criteria for step 1, presentation of sales taxes and other similar taxes collected from customers, non-cash consideration, contract modification at transition, completed contracts at transition and technical correction.

The Company adopted the new standard on January 1, 2018 using the modified retrospective method at the date of adoption and it did not have a material impact on its consolidated financial statements. See Note 2 for additional information on Revenue Recognition.

Recently adopted ASUs - Other

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The objective of the standard is to reduce the existing diversity in practice of several cash flow issues, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payment made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. The guidance in ASU 2016-15 is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted and is to be applied on retrospective basis. The Company adopted this update on January 1, 2018 and it did not have a material impact on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations-Clarifying the Definition of a Business (“ASU 2017-01”). The guidance in ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The guidance provides a screen to determine when a set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The guidance in ASU 2017-01 is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein. The Company adopted this update effective January 1, 2018. The adoption of this update did not have a material impact on its consolidated financial statements.

Recently issued ASUs - Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification (“ASU 2016-02”). In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 (“ASU 2018-01”). In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). Together these related amendments to GAAP represent ASC Topic 842, Leases (“ASC Topic 842”).

ASC Topic 842 requires lessees to recognize lease assets and liabilities (with terms in excess of 12 months) on the balance sheet, disclose key quantitative and qualitative information about leasing arrangements, and permits an entity not to evaluate existing or expired land easements that were not previously assessed under Topic 840. Public entities are required to apply ASC Topic 842 for annual and interim reporting periods beginning after December 15, 2018 with early adoption permitted. The Company expects the adoption of ASC Topic 842 to primarily impact the asset and liability balances on the balance sheet and will continue to evaluate the effect it will have on its consolidated financial statements and related disclosures. As permitted by ASC Topic 842, the Company does not expect to adjust comparative-period financial statements.

Recently issued ASUs - Other

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). The standard is intended to simplify several aspects of the accounting for nonemployee share-based payment transactions for acquiring goods and services from nonemployees, including the timing and measurement of nonemployee awards. The guidance in ASU 2018-06 is effective for public entities for annual reporting periods beginning after December 15, 2018, including interim periods therein. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is currently evaluating the impact of its pending adoption of this guidance on its consolidated financial statements.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

Revenue from contracts with customers

Oil sales

Under the Company’s oil sales contracts it sells oil production at the point of delivery and collects an agreed upon index price, net of pricing differentials. The Company recognizes revenue when control transfers to the purchaser at the point of delivery at the net price received.

Natural gas sales

Under the Company’s natural gas sales processing contracts, it delivers natural gas to a midstream processing entity. The midstream processing entity gathers and processes the natural gas and remits proceeds to the Company for the resulting sale of natural gas. The revenue received from the sale of NGLs is included in the natural gas sales. Under these processing agreements, when control of the natural gas changes at the point of delivery, the treatment of gathering and treating fees are recorded net of revenues. Gathering and treating fees have historically been recorded as an expense in lease operating expense in the statement of operations. The Company has modified the presentation of revenues and expenses to include these fees net of revenues. For the three and six months ended June 30, 2018, $1,952 and $3,204 of gathering and treating fees were recognized and recorded as a reduction to natural gas revenues in the consolidated statement of operations, respectively. For the three and six months ended June 30, 2017, $761 and $1,484 of gathering and treating fees were recognized and recorded as part of lease operating expense in the consolidated statement of operations, respectively.

Production imbalances

Previously, the Company elected to utilize the entitlements method to account for natural gas production imbalances, which is no longer applicable. In conjunction with the Company’s adoption of the new revenue recognition accounting standards, there was no material impact to the financial statements due to this change in accounting for its production imbalances.

Transaction price allocated to remaining performance obligations

For the Company’s product sales that have a contract term greater than one year, it has utilized the practical expedient in Accounting Standards Codification 606-10-50-14, which states the Company is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Prior period performance obligations

The Company records revenue in the month production is delivered to the purchaser. However, settlement statements for sales may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. The Company has existing internal controls for its revenue estimation process and related accruals, and any identified differences between its revenue estimates and actual revenue received historically have not been significant.

Acquisitions 

Acquisitions were accounted for under the acquisition method of accounting, which involves determining the fair value of the assets acquired and liabilities assumed under the income approach.

2018 Acquisitions

On May 23, 2018, the Company entered into a definitive purchase and sale agreement with Cimarex Energy Company for the acquisition of approximately 47,538 gross (28,657 net) acres in the Spur operating area, located in the Delaware Basin, for an aggregate cash purchase price of $570,000, subject to customary purchase price adjustments (the “Cimarex Acquisition”). In connection with the execution of the purchase and sale agreement, the Company paid a deposit in the amount of $28,500, which was recorded as Acquisition deposit on the balance sheet as of June 30, 2018. The Company issued debt and equity to fund, in part, the Cimarex Acquisition. See Notes 5 and 10 for additional information regarding the Company’s debt obligations and equity offerings.

The Company plans to file separate financial statements and pro forma financial information, as required by SEC rules, in a Current Report on Form 8-K within the prescribed 75 day period following consummation of the Cimarex Acquisition.

During the first quarter of 2018, the Company completed acquisitions of additional working interests and acreage in the Company’s existing core operating areas of Monarch and Wildhorse, located in the Permian Basin, for an aggregate total purchase price of approximately $35,900 excluding customary purchase price adjustments.

2017Acquisitions

On February 13, 2017, the Company completed the acquisition of 29,175 gross (16,688 net) acres in the Delaware Basin, primarily located in Ward and Pecos Counties, Texas from American Resource Development, LLC, for total cash consideration of $646,559 excluding customary purchase price adjustments (the “Ameredev Transaction”). The Company funded the cash purchase price with the net proceeds of an equity offering (see Note 10 for additional information regarding the equity offering). The Company obtained an 82% average working interest (75% average net revenue interest) in the properties acquired in the Ameredev Transaction. In December 2016, in connection with the execution of the purchase and sale agreement for the Ameredev Transaction, the Company paid a deposit in the amount of $46,138 to a third party escrow agent, which was recorded as Acquisition deposit on the balance sheet as of December 31, 2016. The following table summarizes the estimated acquisition date fair values of the acquisition:

Evaluated oil and natural gas properties	$	137,368
Unevaluated oil and natural gas properties	509,359
Asset retirement obligations	(168		)
Net assets acquired	$	646,559

On June 5, 2017, the Company completed the acquisition of 7,031 gross (2,488 net) acres in the Delaware Basin, located near the acreage acquired in the Ameredev Transaction discussed above, for total cash consideration of $52,500 excluding customary purchase price adjustments. The Company funded the cash purchase price with its available cash and proceeds from the issuance of an additional $200,000 of its 6.125% senior notes due 2024 (see Note 5 for additional information regarding the Company’s debt obligations).

Unaudited pro forma financial statements

The following unaudited summary pro forma financial information for the periods presented is for illustrative purposes only and does not purport to represent what the Company’s results of operations would have been if the Ameredev Transaction had occurred as presented, or to project the Company’s results of operations for any future periods:

(a) The pro forma financial information was prepared assuming the Ameredev Transaction occurred as of January 1, 2016.

The pro forma adjustments are based on available information and certain assumptions that management believes are reasonable, including revenue, lease operating expenses, production taxes, depreciation, depletion and amortization expense, accretion expense, interest expense and capitalized interest.

The properties associated with the Ameredev Transaction have been commingled with the Company’s existing properties and it is impractical to provide the stand-alone operational results related to these properties.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities

Objectives and strategies for using derivative instruments

The Company is exposed to fluctuations in oil and natural gas prices received for its production. Consequently, the Company believes it is prudent to manage the variability in cash flows on a portion of its oil and natural gas production. The Company utilizes a mix of collars, swaps, put and call options and similar derivative financial instruments to manage fluctuations in cash flows resulting from changes in commodity prices. The Company does not use these instruments for speculative or trading purposes.

Counterparty risk and offsetting

The use of derivative instruments exposes the Company to the risk that a counterparty will be unable to meet its commitments. While the Company monitors counterparty creditworthiness on an ongoing basis, it cannot predict sudden changes in counterparties’ creditworthiness. In addition, even if such changes are not sudden, the Company may be limited in its ability to mitigate an increase in counterparty credit risk. Should one of these counterparties not perform, the Company may not realize the benefit of some of its derivative instruments under lower commodity prices while continuing to be obligated under higher commodity price contracts subject to any right of offset under the agreements. Counterparty credit risk is considered when determining the fair value of a derivative instrument; see Note 7 for additional information regarding fair value.

The Company executes commodity derivative contracts under master agreements with netting provisions that provide for offsetting assets against liabilities. In general, if a party to a derivative transaction incurs an event of default, as defined in the applicable agreement, the other party will have the right to demand the posting of collateral, demand a cash payment transfer or terminate the arrangement.

Financial statement presentation and settlements

Settlements of the Company’s derivative instruments are based on the difference between the contract price or prices specified in the derivative instrument and a benchmark price, such as the NYMEX price. To determine the fair value of the Company’s derivative instruments, the Company utilizes present value methods that include assumptions about commodity prices based on those observed in underlying markets. See Note 7 for additional information regarding fair value.

Derivatives not designated as hedging instruments

The Company records its derivative contracts at fair value in the consolidated balance sheets and records changes in fair value as a gain or loss on derivative contracts in the consolidated statements of operations. Cash settlements are also recorded as a gain or loss on derivative contracts in the consolidated statements of operations.

The following table reflects the fair value of the Company’s derivative instruments for the periods presented:

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The fair value hierarchy included in GAAP gives the highest priority to Level 1 inputs, which consist of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable, and these valuations have the lowest priority.

Fair value offinancial instruments

Cash, cash equivalents, and restricted investments. The carrying amounts for these instruments approximated fair value due to the short-term nature or maturity of the instruments.

Debt. The carrying amount of the Company’s floating-rate debt approximated fair value because the interest rates were variable and reflective of market rates.

	June 30, 2018				December 31, 2017
	Carrying Value		Fair Value		Carrying Value		Fair Value
Credit Facility (a)	$	—	$	—	$	25,000	$	—

Total	$	988,459	$	1,007,500	$	620,196	$	618,000

(a) Floating-rate debt.

(b) The fair value was based upon Level 2 inputs. See Note 5 for additional information about the Company’s 6.125% and 6.375% Senior Notes.

Assets and liabilities measured at fair value on a recurring basis

Certain assets and liabilities are reported at fair value on a recurring basis in the consolidated balance sheet. The following methods and assumptions were used to estimate fair value:

Commodity derivative instruments. The fair value of commodity derivative instruments is derived using an income approach valuation model that utilizes market-corroborated inputs that are observable over the term of the derivative contract. The Company’s fair value calculations also incorporate an estimate of the counterparties’ default risk for derivative assets and an estimate of the Company’s default risk for derivative liabilities. The Company believes that the majority of the inputs used to calculate the commodity derivative instruments fall within Level 2 of the fair value hierarchy based on the wide availability of quoted market prices for similar commodity derivative contracts. See Note 6 for additional information regarding the Company’s derivative instruments.

The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis:

Assets andliabilitiesmeasured atfairvalue on anonrecurringbasis

Acquisitions. The Company determines the fair value of the assets acquired and liabilities assumed using the income approach based on expected discounted future cash flows from estimated reserve quantities, costs to produce and develop reserves, and oil and natural gas forward prices. The future net revenues are discounted using a weighted average cost of capital. The discounted future net revenues of proved undeveloped and probable reserves are reduced by an additional reserve adjustment factor to compensate for the inherent risk of estimating the value of unevaluated properties. The fair value measurements were based on Level 2 and Level 3 inputs.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Company provides for income taxes at the statutory rate of 21%. The statutory rate is adjusted for permanent differences expected to be realized, which primarily relate to non-deductible executive compensation expenses, restricted stock windfalls and shortfalls, and state income taxes.

As a result of the write-down of oil and natural gas properties in the latter part of 2015 and the first half of 2016, the Company incurred a cumulative three year loss. Because of the impact the cumulative loss has on the determination of the recoverability of deferred tax assets through future earnings, the Company assessed the ability to realize its deferred tax assets based on the future reversals of existing deferred tax liabilities. Accordingly, the Company established a full valuation allowance for the net U.S. federal deferred tax asset in 2015. In subsequent periods where the Company has recorded pre-tax income, it has reversed a portion of the U.S. federal valuation allowance, net of discrete items, to the extent necessary to offset U.S. federal income tax expense on pre-tax income recorded for the period. Income tax expense recorded in this period relates to deferred State of Texas gross margin tax. The valuation allowance was $38,604 as of June 30, 2018.

10% Series A Cumulative Preferred Stock (“Preferred Stock”)

Holders of the Company’s Preferred Stock are entitled to receive, when, as and if declared by the Company’s Board of Directors, out of funds legally available for the payment of dividends, cumulative cash dividends at a rate of 10.0% per annum of the $50.00 liquidation preference per share (equivalent to $5.00 per annum per share). Dividends are payable quarterly in arrears on the last day of each March, June, September and December when, as and if declared by the Company’s Board of Directors. Preferred Stock dividends were $1,824 and $3,647 for the three and six months ended June 30, 2018 and 2017, respectively.

The Preferred Stock has no stated maturity and is not subject to any sinking fund or other mandatory redemption. The Company may, at its option, redeem the Preferred Stock, in whole or in part, at any time on or after May 30, 2018, by paying $50.00 per share, plus any accrued and unpaid dividends to the redemption date.

Following a change of control in which the Company or the acquirer no longer have a class of common securities listed on a national exchange, the Company will have the option to redeem the Preferred Stock, in whole but not in part, for $50.00 per share in cash plus accrued and unpaid dividends (whether or not declared) to the redemption date. If the Company does not exercise its option to redeem the Preferred Stock upon such change of control, the holders of the Preferred Stock have the option to convert the Preferred Stock into a number of shares of the Company’s common stock based on the value of the common stock on the date of the change of control as determined under the certificate of designations for the Preferred Stock. If the change of control occurred on June 30, 2018, and the Company did not exercise its right to redeem the Preferred Stock, using the closing price of $10.74 as the value of a share of common stock, each share of Preferred Stock would be convertible into approximately 4.7 shares of common stock. If the Company exercises its redemption rights relating to shares of Preferred Stock, the holders of Preferred Stock will not have the conversion right described above.

Commonstock 

On May 30, 2018, the Company completed an underwritten public offering of 25,300,000 shares of its common stock for total estimated net proceeds (after the underwriter’s discounts and estimated offering costs) of approximately $288,389. The Company plans to use proceeds from the offering to partially fund the Cimarex Acquisition, described in Note 3.

On December 19, 2016, the Company completed an underwritten public offering of 40,000,000 shares of its common stock for total estimated net proceeds (after the underwriter’s discounts and estimated offering expenses) of approximately $634,934. Proceeds from the offering were used to substantially fund the Ameredev Transaction, described in Note 3.

Operating leases

As of June 30, 2018 the Company had contracts for five horizontal drilling rigs. The contract terms, as amended effective as of July 9, 2018, will end on various dates between July 2019 and February 2021. All of the drilling rig contracts provide for early termination, with penalties calculated at a reduced daily rate. In the event that Callon terminated all five drilling contracts as of August 6, 2018, the Company would owe a maximum of $31,342 over the remaining terms of the respective contracts, offset by any revenues earned for replacement work subsequently secured by the contractor. Management does not currently anticipate the early termination of any drilling rig contracts.

Other commitments

In March 2018, the Company entered into a contract for dedicated fracturing and pump down perforating crews, which was effective on April 16, 2018. The term of the agreement is for two years from the effective date.

Subsequent Event

Callon Petroleum Operating Company executed a firm transportation agreement for dedicated capacity on a new pipeline system that will connect with a regional gathering system which currently transports oil volumes under long-term agreements from our properties in Howard, Ward, Reagan and Upton counties to multiple marketing points in the Permian Basin. Subject to completion of the new pipeline system, which will have delivery points in several locations along the Gulf Coast, we will have a long-term 15,000 Bbls per day commitment.

Satisfaction of the volume commitments includes volumes produced by us and other third-party working, royalty, and overriding royalty interest owners whose volumes we market on their behalf.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

Unless otherwise indicated, all dollar amounts included within the Footnotes to the Financial Statements are presented in thousands, except for per share and per unit data.

The interim consolidated financial statements of the Company have been prepared in accordance with (1) GAAP, (2) the SEC’s instructions to Quarterly Report on Form 10-Q and (3) Rule 10-01 of Regulation S-X, and include the accounts of Callon Petroleum Company, and its subsidiary, Callon Petroleum Operating Company (“CPOC”). CPOC also has subsidiaries, namely Callon Offshore Production, Inc. and Mississippi Marketing, Inc.

These interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The balance sheet at December 31, 2017 has been derived from the audited financial statements at that date. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the year ended December 31, 2018.

In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments, including normal recurring adjustments and all intercompany account and transaction eliminations, necessary to present fairly the Company’s financial position, the results of its operations and its cash flows for the periods indicated. Certain prior year amounts may have been reclassified to conform to current year presentation.

Accounting Standards Updates (ASUs)

Recently Adopted ASUs - Revenue Recognition

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 replaced most of the existing revenue recognition requirements in GAAP. The standard can be applied using either the full retrospective approach or a modified retrospective approach at the date of adoption.

Throughout 2015 and 2016, the FASB issued several updates to the revenue recognition guidance in Accounting Standards Codification Topic 606 (“ASC 606”). In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU 2014-09 by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net). Under this update, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing. This update clarifies two principles of ASC 606: identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients. This update applies only to the following areas from ASC 606: assessing the collectability criterion and accounting for contracts that do not meet the criteria for step 1, presentation of sales taxes and other similar taxes collected from customers, non-cash consideration, contract modification at transition, completed contracts at transition and technical correction.

The Company adopted the new standard on January 1, 2018 using the modified retrospective method at the date of adoption and it did not have a material impact on its consolidated financial statements. See Note 2 for additional information on Revenue Recognition.

Recently adopted ASUs - Other

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The objective of the standard is to reduce the existing diversity in practice of several cash flow issues, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payment made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. The guidance in ASU 2016-15 is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted and is to be applied on retrospective basis. The Company adopted this update on January 1, 2018 and it did not have a material impact on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations-Clarifying the Definition of a Business (“ASU 2017-01”). The guidance in ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The guidance provides a screen to determine when a set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The guidance in ASU 2017-01 is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein. The Company adopted this update effective January 1, 2018. The adoption of this update did not have a material impact on its consolidated financial statements.

Recently issued ASUs - Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification (“ASU 2016-02”). In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 (“ASU 2018-01”). In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). Together these related amendments to GAAP represent ASC Topic 842, Leases (“ASC Topic 842”).

ASC Topic 842 requires lessees to recognize lease assets and liabilities (with terms in excess of 12 months) on the balance sheet, disclose key quantitative and qualitative information about leasing arrangements, and permits an entity not to evaluate existing or expired land easements that were not previously assessed under Topic 840. Public entities are required to apply ASC Topic 842 for annual and interim reporting periods beginning after December 15, 2018 with early adoption permitted. The Company expects the adoption of ASC Topic 842 to primarily impact the asset and liability balances on the balance sheet and will continue to evaluate the effect it will have on its consolidated financial statements and related disclosures. As permitted by ASC Topic 842, the Company does not expect to adjust comparative-period financial statements.

Recently issued ASUs - Other

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). The standard is intended to simplify several aspects of the accounting for nonemployee share-based payment transactions for acquiring goods and services from nonemployees, including the timing and measurement of nonemployee awards. The guidance in ASU 2018-06 is effective for public entities for annual reporting periods beginning after December 15, 2018, including interim periods therein. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is currently evaluating the impact of its pending adoption of this guidance on its consolidated financial statements.
