“Our 2019 results highlight the strength of our company, which was demonstrated by the generation of record levels for net income, operating cash flow, free cash flow, production, proved reserves and operating expenses,” said Dan O. Dinges, Chairman, President and Chief Executive Officer. “While we continue to manage through headwinds from lower natural gas prices, our low cost structure and low leverage position will allow us to continue to generate positive free cash flow and economic corporate returns, maintain our financial strength, and return capital to shareholders during these challenging times for the natural gas markets.”

• Net income of $681.1 million (or $1.64 per share); adjusted net income (non-GAAP) of $698.8 million (or $1.68 per share)

• Free cash flow (non-GAAP) of $563.1 million, marking the fourth consecutive year of positive free cash flow

• Return on capital employed (ROCE) (non-GAAP) of 22.2 percent

• Returned $665.4 million of capital to shareholders through dividends and share repurchases, including a 43 percent increase in the quarterly dividend per share and a seven percent reduction in weighted-average shares outstanding

• Production of 865.3 billion cubic feet equivalent (Bcfe), an increase of 18 percent year-over-year

• Proved reserves of 12.9 trillion cubic feet equivalent (Tcfe), an increase of 11 percent year-over-year

• Reduced net debt-to-EBITDAX (non-GAAP) to 0.7x at year-end 2019

See the supplemental tables at the end of this press release for a reconciliation of non-GAAP measures including adjusted net income, discretionary cash flow, EBITDAX, free cash flow, net debt to adjusted capitalization ratio, ROCE, pre-tax present value of future net cash flows (pre-tax PV-10) and F&D costs.

Fourth Quarter 2019 Financial Results

Return of Capital

Cabot returned $665.4 million of capital to shareholders through dividends and share repurchases in 2019, representing 118 percent of the Company’s free cash flow. During the year, Cabot increased its quarterly dividend per share by 43 percent and repurchased 25.5 million shares. Since reactivating the share repurchase program in the second quarter of 2017, Cabot has reduced its shares outstanding by over 14 percent to 398.6 million shares. The Company currently has 11.0 million remaining shares authorized under its share repurchase program (or approximately three percent of its current shares outstanding). Cabot continues to target a minimum return of capital of at least 50 percent of free cash flow annually.

Financial Position and Liquidity

As of December 31, 2019, Cabot had total debt of $1.2 billion and cash on hand of $200.2 million. The Company's net debt-to-adjusted capitalization ratio and net debt-to-trailing twelve months EBITDAX ratio were 32.2 percent and 0.7x, respectively, compared to 37.0 percent and 1.0x as of December 31, 2018. The Company currently has no debt outstanding under its credit facility, resulting in approximately $1.7 billion of liquidity.

Upper Marcellus Operations Update

During 2018 and 2019, Cabot placed 25 Upper Marcellus wells on production. Excluding four wells that were located on a pad where the Company had an underperforming lateral placement pilot test, the average estimated ultimate recovery (EUR) per thousand lateral feet was 2.7 Bcf. "We believe the results from our recent Upper Marcellus wells highlight the Upper Marcellus as a distinct, economic interval that exceeds the average well productivity across the basin,” stated Dinges. “Our prolific acreage position in northeast Pennsylvania provides us with over two decades of remaining drilling locations, including nine years of remaining Lower Marcellus inventory.” The Company plans to test an additional five Upper Marcellus wells in 2020 to further optimize lateral placement and completion design.

Year-End 2019 Proved Reserves

Cabot reported year-end proved reserves of 12.9 Tcfe, an increase of 11 percent over year-end 2018. The table below reconciles the components driving the 2019 reserve increase:

Proved Reserves Reconciliation (in Bcfe)
Balance at December 31, 2018	11,605
Revisions of prior estimates	47
Extensions, discoveries and other additions	2,116
Production	(865	)	)
Balance at December 31, 2019	12,903

As of December 31, 2019, 100 percent of Cabot’s year-end proved reserves were natural gas and were located in the Marcellus Shale. Approximately 62 percent of the year-end proved reserves were classified as proved developed and 38 percent were classified as proved undeveloped (PUD), including six percent of drilled and uncompleted PUDs

Total costs incurred during 2019 were $787.7 million, which included $761.3 million for development costs, $20.3 million for exploration costs, and $6.1 million for lease acquisition costs. All-sources F&D costs (non-GAAP) were $0.36 per Mcfe, while drill-bit F&D costs (non-GAAP) were $0.37 per Mcfe in 2019.

The SEC price used for reporting Cabot's year-end 2019 proved reserves, which has been adjusted for basis and quality differentials, was $2.35 per Mcf, a nine percent year-over-year decrease. Assuming the SEC price, the pre-tax PV-10 (non-GAAP) of the year-end 2019 proved reserves was $7.5 billion, an eight percent decrease compared to $8.1 billion at year-end 2018.

First Quarter and Full-Year 2020 Guidance

Cabot has provided its first quarter 2020 production guidance range of 2,350 to 2,400 Mmcfe per day, representing a three percent sequential decline at the midpoint of the range relative to the fourth quarter of 2019. Based on the timing of wells being placed on production throughout the year, the Company anticipates an additional sequential decline in the second quarter of 2020 before increasing volumes in the second half of the year.

Cabot has also reaffirmed its recently announced plan to deliver an average net production rate of approximately 2,400 Mmcfe per day in 2020 from a capital program of $575 million. Based on the current NYMEX futures curve, this plan is expected to generate enough free cash flow to cover the Company’s dividend while also providing a modest amount of excess free cash flow for further return of capital to

5

shareholders or debt repayment. At a $2.25 average NYMEX price, the plan is expected to deliver between $275 and $300 million of free cash flow and generate a return on capital employed between 11 and 12 percent. The Company continues to analyze the outlook for the natural gas markets in 2020 and beyond and is prepared to reduce capital spending further if market conditions warrant it.

Explanation and Reconciliation of Non-GAAP Financial Measures

We report our financial results in accordance with accounting principles generally accepted in the United States (GAAP). However, we believe certain non-GAAP performance measures may provide financial statement users with additional meaningful comparisons between current results and results of prior periods. In addition, we believe these measures are used by analysts and others in the valuation, rating and investment recommendations of companies within the oil and natural gas exploration and production industry. See the reconciliations throughout this release of GAAP financial measures to non-GAAP financial measures for the periods indicated.

We have also included herein certain forward-looking non-GAAP financial measures. Due to the forward-looking nature of these non-GAAP financial measures, we cannot reliably predict certain of the necessary components of the most directly comparable forward-looking GAAP measures, such as future impairments and future changes in capital. Accordingly, we are unable to present a quantitative reconciliation of such forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures. Reconciling items in future periods could be significant.

Reconciliation of Net Income to Adjusted Net Income and Adjusted Earnings Per Share

Adjusted Net Income and Adjusted Earnings per Share are presented based on our belief that these non-GAAP measures enable a user of the financial information to understand the impact of these items on reported results. Adjusted Net Income is defined as net income plus gain and loss on sale of assets, gain and loss on derivative instruments, gain on sale of equity method investment, stock-based compensation expense, severance expense, interest expense related to income tax reserves and tax effect on selected items. Additionally, this presentation provides a beneficial comparison to similarly adjusted measurements of prior periods. Adjusted Net Income and Adjusted Earnings per Share are not measures of financial performance under GAAP and should not be considered as alternatives to net income and earnings per share, as defined by GAAP.

Return on Capital Employed

Return on Capital Employed (ROCE) is defined as Adjusted Net Income (defined above) plus after-tax net interest expense divided by average capital employed, which is defined as total debt plus stockholders’ equity. ROCE is presented based on our belief that this non-GAAP measure is useful information to investors when evaluating our profitability and the efficiency with which we have employed capital over time. ROCE is not a measure of financial performance under GAAP and should not be considered an alternative to net income.

Discretionary Cash Flow and Free Cash Flow Calculation and Reconciliation

Discretionary Cash Flow is defined as net cash provided by operating activities excluding changes in assets and liabilities. Discretionary Cash Flow is widely accepted as a financial indicator of an oil and gas company’s ability to generate cash which is used to internally fund exploration and development activities, pay dividends and service debt. Discretionary Cash Flow is presented based on our belief that this non-GAAP measure is useful information to investors when comparing our cash flows with the cash flows of other companies that use the full cost method of accounting for oil and gas producing activities or have different financing and capital structures or tax rates. Discretionary Cash Flow is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating activities, as defined by GAAP, or as a measure of liquidity, or an alternative to net income.

Free Cash Flow is defined as Discretionary Cash Flow (defined above) less capital expenditures and investment in equity method investments. Free Cash Flow is an indicator of a company's ability to generate cash flow after spending the money required to maintain or expand its asset base. Free Cash Flow is presented based on our belief that this non-GAAP measure is useful information to investors when comparing our cash flows with the cash flows of other companies. Free Cash Flow is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating activities, as defined by GAAP, or as a measure of liquidity, or an alternative to net income.

EBITDAX Calculation and Reconciliation

EBITDAX is defined as net income plus interest expense, other expense, income tax expense, depreciation, depletion and amortization (including impairments), exploration expense, gain and loss on sale of assets, non-cash gain and loss on derivative instruments, earnings and loss on equity method investments, cash distributions received from equity method investments, and stock-based compensation expense. EBITDAX is presented based on our belief that this non-GAAP measure is useful information to investors when evaluating our ability to internally fund exploration and development activities and to service or incur debt without regard to financial or capital structure. EBITDAX is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating activities or net income, as defined by GAAP, or as a measure of liquidity.

Net Debt Reconciliation

The total debt to total capitalization ratio is calculated by dividing total debt by the sum of total debt and total stockholders’ equity. This ratio is a measurement which is presented in our annual and interim filings and we believe this ratio is useful to investors in determining our leverage. Net Debt is calculated by subtracting cash and cash equivalents from total debt. Net Debt and the Net Debt to Adjusted Capitalization ratio are non-GAAP measures which we believe are also useful to investors since we have the ability to and may decide to use a portion of our cash and cash equivalents to retire debt. Additionally, as we may incur additional expenditures without increasing debt, it is appropriate to apply cash and cash equivalents to debt in calculating the Net Debt to Adjusted Capitalization ratio.

Finding and Development Costs

Drill-Bit Finding and Development Cost is defined as costs incurred in exploration and development activities as defined by GAAP divided by reserve extensions, discoveries and other additions. All-Sources Finding and Development Cost is defined as costs incurred in property acquisition, exploration and development activities, as defined by GAAP, divided by the total of reserve extensions, discoveries and other additions and revision of prior estimates. Drill-Bit Finding and Development Cost and All-Sources Finding and Development Cost are presented based on management's belief that these non-GAAP measures are useful information to investors to evaluate how much it costs to add proved reserves. These calculations do not include the future development costs required for the development of proved undeveloped reserves and may not be comparable to similarly titled measurements used by other companies.

Pre-Tax Present Value of Future Net Cash Flows Calculation and Reconciliation

Pre-Tax Present Value of Future Net Cash Flows, discounted at 10% annual rate (Pre-Tax PV-10), is defined as Standardized Measure of Discounted Future Net Cash Flows plus Future Income Tax Expenses, discounted at 10% annual rate. Year-end Pre-Tax PV-10 value is presented based on our belief that this non-GAAP measure is useful information to investors and creditors when comparing Pre-Tax PV-10 values as a basis for comparison of our relative size and value of reserves as compared with other companies. Pre-Tax PV-10 is not a measure under GAAP and should not be considered as alternative to Standardized Measure of Discounted Future Net Cash Flows, as defined by GAAP.
