Report of Independent Registered Public Accounting Firm

To the Participants and Administrator of

Energen Corporation Employee Savings Plan

In our opinion, the accompanying statements of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the Energen Corporation Employee Savings Plan (the “Plan”) at December 31, 2006 and 2005 and the changes in net assets available for benefits for the year ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Plan’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of Assets (Held at End of Year) and of Reportable Transactions are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan’s management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

1. Description of Plan

The following description of the Energen Corporation Employee Savings Plan (the “Plan”) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan’s provisions.

General

The Plan was established to cover substantially all employees of Energen Corporation and its subsidiaries (the “Employer”). The Plan is a defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974.

Employees are eligible to participate in the Plan after completing three months of service as defined in the Plan agreement.

The Plan is administered by the Energen Benefits Committee (“Administrative Committee”) whose members are appointed by the Board of Directors of the Employer. The assets of the Plan are held and invested by Vanguard Fiduciary Trust Company (the “Trustee”). Accordingly, all investment transactions with the Trustee qualify as party-in-interest transactions.

Contributions

Contributions to the Plan may consist of employee elective contributions, employer matching contributions and Employee Stock Ownership Plan (“ESOP”) contributions, and rollover contributions. Employee elective contributions, if any, are made by payroll deduction in an amount equal to any whole percentage of the employee’s compensation (limited to the first $220,000 of the employee’s compensation for the year ending December 31, 2006), not to exceed 30% thereof and not less than 2% thereof. Employer matching contributions are invested directly into the Energen Stock Fund. This contribution is currently 50% of each employee’s elective contribution not to exceed 6% of the employee’s compensation. The Employer has the discretion to increase the employer matching contribution percentage.

Effective January 1, 2006, the Plan was amended to take advantage of “safe harbor” rules under the Internal Revenue Code (“IRC”). For participants of the Plan on and beginning January 1, 2006, the Employer will contribute a safe harbor contribution equal to 3% of his/her pay for the Plan year, regardless of any employee deferral contributions that are made. This safe harbor contribution will be made to the ESOP portion of the Plan. Participants will be fully vested in the Employer’s safe harbor contribution and matching contribution.

In addition, effective January 1, 2006, the option that allowed salaried employees to use residual flex credits as a contribution to the Plan was removed.

Investment Options

The Plan provides for separate investment programs, which allow participants to direct their investing among the different investment options. The Plan offers sixteen mutual funds and one money market fund as investment options for participants. Effective January 1, 2004, the Energen Stock Fund was no longer offered to participants as an elective investment option.

Prior to December 31, 1986, there was a life insurance option available to participants of the Plan. No new contracts may be purchased under this option; however, participants that were enrolled in this option may still contribute to this fund, which invests in universal life insurance policies. The insurance premium amounts are deducted from the participant’s pay on a tax deferred basis along with other employee elective contributions to the Plan. The Employer then directly remits payment to the insurance company to cover the insurance premiums.

Participant Loans

Participants may borrow from their accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance as defined in the Plan agreement. Loan transactions are treated as transfers between the investment fund and the participant loan fund. Loans must be repaid within five years unless such loan is used to acquire a principal residence. Interest rates on outstanding loans ranged from 5% to 10.5% and 6.25% to 10.5% at December 31, 2006 and 2005, respectively.

Participants’ Accounts/Benefits

An account is maintained for each participant in the Plan. The accounts are credited with the employees’ elective and rollover contributions, their allocated portion of the employer matching and employer ESOP contributions, and investment earnings. Distributions, withdrawals, and allocated expenses are subtracted from the account balances.

A participant may elect to receive a lump-sum distribution equal to the vested balance of his/her account or may leave it in the Plan if the vested balance is $5,000 or more. Effective March 28, 2005, a participant may elect to defer payment of his/her benefit if the vested balance is $1,000 or more. Investment of a participant’s account in the Energen Stock Fund shall be distributed in the form of a lump-sum distribution of either Energen stock or cash as the participant (or beneficiary) elects.

Vesting

Effective January 1, 2006, each participant has a fully vested interest in their total account in the Plan.

Each individual, who is not an eligible employee on or after January 1, 2006, shall have a fully vested and nonforfeitable right to all employee elective and rollover contributions and earnings thereon. A participant’s employer matching and employer ESOP contribution accounts become fully vested upon the earlier of normal retirement, disability, death, termination of the Plan, three years of service as a plan member, or three years of service.

Forfeitures

The Employer uses all forfeitures to reduce subsequent employer contributions to the Plan. At December 31, 2006, the unused forfeiture balance was approximately $136,858.

Termination

The Employer retains the right to amend or terminate the Plan at any time. No amendment may permit any Plan assets to revert to the Employer, reduce a participant’s benefit, or be used for any purpose other than to provide benefits to participants and their beneficiaries. In the event of termination, the Administrative Committee may, with the Employer’s approval, either (1) continue the Vanguard Fiduciary Trust Company Trust Fund (“Trust Fund”) either through the existing trust agreement or through successor funding media or (2) terminate the Trust Fund, pay all expenses, and direct the payment of benefits, either in the form of lump-sum distributions, transfers to another qualified plan, or any other form selected by the Administrative Committee. Any asset not required to be distributed to participants will be returned to the Employer.

2. Summary of Significant Accounting Policies

Basis of Financial Statements

The financial statements of the Plan are maintained on the accrual basis and have been prepared in conformity with accounting principles generally accepted in the United States of America.

Investments

The Energen Stock Fund is valued at fair value based on quoted market prices of the Energen Corporation common stock plus the fair value of the cash portion of the Energen Stock Fund. Quoted market prices are based on the last reported sales price on the last business day of the year as reported by the principal securities exchange on which the security is traded. Mutual funds are reported at fair value based on the quoted net asset value of shares of the fund. The money market fund is valued based on historical cost, which approximates fair value. Participant loans are valued at their outstanding balances, which approximate fair value. The life insurance contracts are valued at cash surrender value.

Purchases and sales of investments are reflected as of the trade date. Dividend income is recorded on the ex-dividend date. Investment income is recorded when earned.

The Plan presents in the statement of changes in net assets available for benefits, the net appreciation (depreciation) in the fair value of its investments which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments.

Administrative Fees

The Employer provides certain administrative and accounting services to the Plan at no cost and also pays certain other administrative expenses on behalf of the Plan.

Payment of Benefits

Benefits are recorded when paid.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from those estimates.

Risks and Uncertainties

The Plan provides for various investment options which, in turn, invest in any combination of stocks, mutual funds, and other investment securities. Generally, all investments are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the value of investments, it is at least reasonably possible that changes in risks in the near term could materially affect participants’ account balances, and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.

 

3. Income Tax Status

The Plan obtained its latest determination letter on October 6, 2003, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the IRC and was, therefore, exempt from federal income taxes. The Plan has been amended

since receiving the determination letter. However, the Plan’s administrator and the Plan’s tax counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been included in the Plan’s financial statements.
