Bill Barrett Corporation Reports 2013 Financial and Operating Results

Including Discretionary Cash Flow of $281 million or $5.92 per Share

DENVER – February 20, 2014 – Bill Barrett Corporation (NYSE: BBG) today reported 2013 results and announced operational updates including:

Chief Executive Officer Scot Woodall commented: “In 2013, we delivered on our key operating and financial objectives. We ended 2013 having achieved a commodity balanced portfolio, successfully delineated 70% of our net Northeast Wattenberg position, substantially increased proved oil reserves and reduced our long-term debt by $189 million. In combination, these achievements position our company for growth in oil production and cash flow in 2014 and forward.

“In the DJ Basin, we tested a number of concepts in combination with delineating the majority of our position and will expand our program there in 2014. Well results in the area to date have been as projected, accounting for the variability expected in a delineation program. We plan to invest approximately 75% of the 2014 capital budget in the DJ with a three-rig program. Drilling will be focused on all three portions of our DJ Basin acreage and includes predominantly pad (multi-well) drilling. We will also drill a number of extended reach laterals. In the East Bluebell area of the Uinta Oil Program, we remain very pleased with the strong returns and will continue with one-two rigs in that area during 2014.

“In 2014, we will continue to build value through the development of our core oil programs. Our commodity balanced portfolio is expected to deliver higher margins as we grow production in 2014 and beyond.”

OPERATING AND FINANCIAL RESULTS

Total estimated proved reserves at year-end 2013 were 197 million barrels of oil equivalent (“MMBoe”). Estimated proved reserves were 42% oil, 18% natural gas liquids (“NGLs”) and 40% natural gas and were 42% developed and 58% undeveloped. Based on adjusted costs incurred (a non-GAAP measure, see “Costs Incurred and Reserve Information” schedule below) of $472.1 million, estimated reserve additions were made at an average cost of $8.30 per Boe.

Oil and natural gas production totaled 14.5 MMBoe in 2013 compared with 19.6 MMBoe in 2012. Oil production increased 30% to 3.5 million barrels (“MMBbls”) from 2.7 MMBbls in 2012. Growth in oil production was more than offset by declines in natural gas production as a result of asset sales and natural production declines as the Company did not drill during 2013 at its natural gas programs. Fourth quarter production was 3.3 MMBoe, down from 4.7 MMBoe in the fourth quarter of 2012. 2013 exit rate production was 40% oil, adjusted for the sale of West Tavaputs and a reduced working interest in Gibson Gulch in the Piceance Basin.

Realized pricing, including the effects of the Company’s hedging activities, was $82.38 per barrel of oil, $4.16 per thousand cubic feet (“Mcf”) of natural gas and $28.31 per barrel of NGLs. The average benefit of hedge activity was $0.88 per Boe. While average realized prices were lower in 2013 compared with 2012, the Company realized increased revenue per unit in 2013 due to a higher proportion of oil sales versus natural gas sales. The fourth quarter of 2013 average realized prices were $82.05 per barrel of oil, $4.42 per Mcf of natural gas and $29.79 per barrel of NGLs. (See “Selected Operating Highlights” below for more detail.)

Discretionary cash flow (a non-GAAP measure, see “Discretionary Cash Flow Reconciliation” below) for 2013 was $281.3 million, or $5.92 per diluted common share, down from $402.9 million, or $8.51 per diluted common share, in 2012. The decline in discretionary cash flow is primarily due to a 26% decline in production volumes, as the Company sold assets and transitioned from a natural gas to oil focused operating program. Discretionary cash flow was $77.1 million for the fourth quarter of 2013 compared with $103.5 million for the fourth quarter of 2012.

The Company had a net loss in 2013 of $192.7 million, or ($4.06) per diluted common share, down from net income of $0.6 million, or $0.01 per diluted common share, in 2012. Net income in 2013 was affected by the same reduction in production as discretionary cash flow, as well as impairment, dry hole and abandonment expenses of $238.4 million primarily related to the sale of its West Tavaputs natural gas assets. The Company had a net loss in the fourth quarter of 2013 of $7.2 million compared with net income of $14.0 million in the fourth quarter of 2012. The fourth quarter of 2013 net loss included $10.8 million of impairment, dry hole and abandonment expenses and a $3.0 million loss on property sales.

Adjusted net income (a non-GAAP measure, see “Adjusted Net Income Reconciliation” below) for 2013 was a loss of $20.5 million, or ($0.43) per diluted common share, compared with adjusted net income of $6.9 million, or $0.15 per diluted common share, in 2012. Adjusted net income for the fourth quarter of 2013 was $5.2 million compared with $9.6 million in 2012. Adjusted net income removes the effect of non-recurring charges such as unrealized derivative gains and losses, impairment expenses, property sales and one-time items.

On December 10, 2013, the Company closed on the sale of the West Tavaputs natural gas property located in the Uinta Basin, Utah for a transaction value of $369 million. The transaction value was adjusted to the August 1, 2013 effective date and for other customary closing adjustments, providing net cash proceeds to the Company of $309 million plus the buyer’s assumption of lease financing obligations associated with the property of approximately $46 million. Net cash proceeds from the transaction were applied to pay down the Company’s revolving credit facility.

DEBT AND LIQUIDITY

At December 31, 2013, the Company had borrowing capacity of $484 million and total debt outstanding of $984 million. The Company had $115 million drawn on its revolving credit facility. The facility has a borrowing base of $625 million less an outstanding letter of credit for $26 million. Debt outstanding included $25 million of convertible senior notes, $400 million in 7.625% senior notes, $400 million in 7.000% senior notes and $43 million for a lease financing obligation. The Company has no significant debt maturity before 2016.

DISCLOSURE STATEMENTS

Presentation of Natural Gas Liquids Volumes

Effective January 1, 2013, the Company began reporting its production volumes on a three-stream basis, which separately reports NGLs extracted from the natural gas stream and sold as a distinct product.

2013 year-end reserves are presented on a three-stream basis, and year-end 2012 reserves are recalculated to reflect three-stream volumes for comparability. NGL volumes are converted to an oil equivalent based on 42 gallons per barrel and compared to overall gas equivalent production based on a 1 barrel to 6 Mcf ratio.

Reserve and Resource Disclosure

The SEC permits oil and gas companies to disclose proved, probable and possible reserves in their filings with the SEC. The Company does not plan to include probable and possible reserve estimates in its filings with the SEC.

We may use certain terms, such as “risked resources,” that the SEC’s guidelines strictly prohibit us from including in filings with the SEC. While not referenced in this release, it may be referenced in the earnings conference call following this release. The calculation of risked resources, and any other estimates of reserves and resources that are not proved, probable or possible reserves are not necessarily calculated in accordance with SEC guidelines. Our estimate of risked resources is not prepared or reviewed by third party engineers, is determined using strip pricing, which we use internally for planning and budgeting purposes, and may differ from an un-risked estimate of proved, probable and possible reserves. The Company’s estimate of risked resources is provided in this release because management believes it is useful, additional information that is widely used by the investment community in the valuation, comparison and analysis of companies; however, the Company’s estimate of risked resources may not be comparable to similar metrics provided by other companies. Investors are urged to consider closely the disclosure in our Annual Report on Form 10-K for the year ended December 31, 2013, available on the Company’s website at www.billbarrettcorp.com or from the corporate offices at 1099 18th Street, Suite 2300, Denver, CO 80202. You can also obtain this form from the SEC by calling 1-800-SEC-0330 or at www.sec.gov.

Finding and Development Costs

Finding and development cost is a non-GAAP metric commonly used in the exploration and production industry. Calculations presented by the Company are based on costs incurred, as adjusted by the Company, divided by reserve additions and are unaudited.

Reconciliation of Discretionary Cash Flow & Adjusted Net Income

(Unaudited)

Discretionary Cash Flow Reconciliation

Adjusted Net Income (Loss) Reconciliation

Discretionary cash flow and adjusted net income are non-GAAP measures. These measures are presented because management believes that they provide useful additional information to investors for analysis of the Company’s ability to internally generate funds for exploration, development and acquisitions as well as adjusting net income (loss) for unusual items to allow for a more consistent comparison from period to period. In addition, the Company believes that these measures are widely used by professional research analysts and others in the valuation, comparison and investment recommendations of companies in the oil and gas exploration and production industry, and that many investors use the published research of industry research analysts in making investment decisions.

These measures should not be considered in isolation or as a substitute for net income, income from operations, net cash provided by operating activities or other income, profitability, cash flow or liquidity measures prepared in accordance with GAAP. Because discretionary cash flow and adjusted net income exclude some, but not necessarily all, items that affect net income (loss) and may vary among companies, the amounts presented may not be comparable to similarly titled measures of other companies.
