CURRENT BUSINESS OUTLOOK
Occidental's operations, financial condition, cash flows and levels of expenditures are highly dependent on oil prices and, to a lesser extent, NGL and natural gas prices, the Midland-to-Gulf-Coast oil spreads and the prices it receives for its chemical products. Oil prices have increased significantly in 2021. Occidental's average worldwide realized price for the three months endedJune 30, 2021 was$64.18 , compared to$23.14 in the same period of 2020. While the worldwide economy continues to be impacted by the ongoing effects of the COVID-19 pandemic and emergence and spread of new variants of the virus, demand for Occidental's products has increased with the lifting of certain restrictions, including certain travel restrictions and stay-at-home orders. Subsequent toJune 30, 2021 , members ofOPEC and 10 non-OPEC partner countries (OPEC+) agreed to a phased increase in production over the next eighteen months in anticipation of a return to pre-pandemic oil demand. Current oil prices could be negatively impacted by a resurgence of COVID-19 cases, slow vaccine distribution in certain large international economies, or the recurrence or tightening of travel restrictions and stay-at-home orders. We expect that oil prices in the near-term will continue to be influenced by the duration and severity of the COVID-19 pandemic and its resulting impact on oil and gas demand. Occidental's operational priorities for 2021 continue to be to maximize cash flow by sustaining production in-line with its 2020 fourth quarter rate with an annualized$2.9 billion capital budget and by maintaining a majority of the cost savings achieved in 2020. Occidental intends to use excess cash flow generated during 2021, coupled with divestiture proceeds, to continue to strengthen its balance sheet by reducing its debt and other financial obligations. LIABILITY MANAGEMENT InJuly 2021 , Occidental settled cash tender offers to purchase approximately$3.1 billion in outstanding senior notes, inclusive of accrued interest and premiums, with maturities ranging from 2022 through 2026. Subsequent to the purchase and retirement of these senior notes, Occidental's face value of debt was approximately$32.0 billion . In addition, during the first quarter of 2021, Occidental repaid$174 million of debt upon maturity. Subsequent to the completion of the July tender offers, Occidental has remaining near-term debt maturities of approximately$224 million in 2021,$1.8 billion in 2022 and$465 million in 2023. In addition to the above, Occidental's Zero Coupon senior notes due 2036 (Zero Coupons) can be put to Occidental in October of each year, in whole or in part, for the then accreted value of the outstanding Zero Coupons. The Zero Coupons can next be put to Occidental inOctober 2021 , which, if put in whole, would require a payment of approximately$1.0 billion at such date. Occidental currently has the ability to meet this obligation and may use available capacity under the revolving credit facility (RCF) to satisfy the put should it be exercised. Interest rate swaps with a notional value of$750 million and a fair value of approximately$800 million , as ofJune 30, 2021 , have a mandatory termination date inSeptember 2021 . Occidental intends to cash settle these in the third quarter of 2021. Interest rate swaps with a notional value of$725 million and a fair value of$405 million , net of collateral, as ofJune 30, 2021 , have mandatory termination dates inSeptember 2022 and 2023, respectively. The interest rate swaps' fair value, and cash required to settle on their termination dates, will continue to fluctuate with changes in interest rates through the mandatory termination dates. Depending on market conditions, liability management actions or other factors, Occidental may enter into offsetting interest rate swap positions or amend or settle certain or all of the currently outstanding interest rate swaps, as appropriate. As of the date of this filing, Occidental had$5.0 billion of committed borrowing capacity under its RCF, which matures inJanuary 2023 . Additionally, Occidental has up to$400 million of capacity, subject to monthly redetermination, under its receivables securitization facility, which matures inNovember 2022 . Occidental continues to pursue divestitures of certain assets and intends to use excess cash flow and the net proceeds from asset sales to repay debt maturities and other financial obligations, however the expected timing and final proceeds from such asset sales are uncertain. Occidental expects its cash on hand and funds available under its RCF to be sufficient to meet its near-term debt maturities, operating expenditures and other obligations for the next 12 months from the date of this filing. DEBT RATINGS As ofJune 30, 2021 , Occidental's long-term debt was rated Ba2 by Moody's Investors Service, BB by Fitch Ratings and BB- by Standard and Poor's. Any downgrade in credit ratings could impact Occidental's ability to access capital and increase its cost of capital. In addition, given that Occidental's current debt ratings are non-investment grade, Occidental may be requested, and in some cases be required, to provide collateral in the form of cash, letters of credit, surety bonds or other acceptable support as financial assurance of its performance and payment obligations under certain contractual arrangements such as pipeline transportation contracts, environmental remediation obligations, oil and gas purchase contracts and certain derivative instruments. As of the date of this filing, Occidental has provided required financial assurances through a combination of cash, letters of credit and surety bonds made available to it on a bilateral basis and has not issued any letters of credit under the RCF or other committed facilities. For additional information, see Risk Factors in Part I, Item 1A of Occidental's 2020 Form 10-K. 26 -------------------------------------------------------------------------------- IMPACT OF COVID-19 PANDEMIC TO GLOBAL OPERATIONS Occidental continues to focus on protecting the health and safety of its employees and contractors during the COVID-19 pandemic. Certain workplace restrictions implemented in the initial stages of the pandemic for our offices and work sites for health and safety reasons were lifted in the second quarter of 2021 due to higher vaccination rates and lower infection rates. Other restrictions remain in place. Occidental has not incurred material costs as a result of new protocols and procedures. Occidental continues to monitor national, state and local government directives where it has operations and/or offices. While Occidental has not incurred any significant disruptions to its day-to-day operations as a result of any workplace restrictions related to the COVID-19 pandemic to date, the situation is still rapidly changing with the emergence and spread of new variants and the extent to which the COVID-19 pandemic adversely affects the business, results of operations and financial condition will depend on future developments, which remain uncertain.
CONSOLIDATED RESULTS OF OPERATIONS
Occidental reported after-tax income from continuing operations of$100 million on net sales of$6.0 billion , for the three months endedJune 30, 2021 , compared to an after tax loss from continuing operations of$6.7 billion on net sales of$2.9 billion for the same period of 2020. Diluted loss from continuing operations per share was$0.11 for the three months endedJune 30, 2021 compared to$7.58 for the same period of 2020. Occidental reported after-tax income from continuing operations of$399 million on net sales of$11.3 billion for the six months endedJune 30, 2021 , compared to an after-tax loss from continuing operations of$8.7 billion on net sales of$9.5 billion for the same period of 2020. Diluted loss from continuing operations per share was zero for the six months endedJune 30, 2021 compared to$10.12 for the same period of 2020. Excluding the impact of asset impairments, gains and losses on sales of assets and equity investments, gains and losses on derivative mark-to-market adjustments and acquisition-related costs, the increase in income from continuing operations for the three and six months endedJune 30, 2021 , compared to the same periods in 2020, was primarily related to higher crude oil, NGL and natural gas prices, higher marketing margins and increases in prices across most chemical product lines, partially offset by lower crude oil sales volumes, higher depreciation, depletion and amortization (DD&A) rates and higher chemical ethylene and energy costs. SELECTED STATEMENTS OF OPERATIONS ITEMS Net sales increased for the three and six months endedJune 30, 2021 , compared to the same periods in 2020, primarily as a result of higher crude oil, NGL and natural gas prices, increases in prices across most chemical product lines and higher marketing margins, partially offset by lower crude oil sales volumes. Oil and gas operating expenses decreased for the six months endedJune 30, 2021 , compared to the same period in 2020, as a result of lower oil and gas production volumes. Transportation and gathering expenses decreased for the six months endedJune 30, 2021 , compared to the same period in 2020, primarily as a result of lower domestic oil and gas production volumes. The cost of purchased commodities increased for the three and six months endedJune 30, 2021 , compared to the same periods in 2020, due to higher crude prices on third-party crude purchases related to the midstream and marketing segment. DD&A expense increased for the three and six months endedJune 30, 2021 compared to the same periods in 2020, as a result of higher DD&A rates due to lower reported proved reserves volumes, consistent with lower average prices in 2020. Occidental undertook a mid-year reserve review, which will result in lower DD&A rates for the second half of 2021 due to increased proved reserves primarily related to positive price revisions. Proved oil, NGL and natural gas reserves were estimated during this mid-year review using the unweighted arithmetic average of the first-day-of-the-month price for each month for the twelve months endedJune 30, 2021 , unless prices were defined by contractual arrangements. Asset impairments and other charges for the three months endedJune 30, 2020 included$6.4 billion in pre-tax impairments on oil and gas proved and unproved properties. In addition, asset impairments and other charges for the six months endedJune 30, 2020 included a$1.2 billion impairment of goodwill attributable to Occidental's ownership in WES as well as$546 million of other impairments on proved and unproved oil and gas properties. Gains (losses) on interest rate swaps and warrants, net, increased for the six months endedJune 30, 2021 , compared to the same period in 2020, primarily due to rising interest rates in the first quarter of 2021, resulting in a favorable change in the fair value of interest rate swaps. Income from equity investments for the six months endedJune 30, 2020 included a loss of approximately$240 million from WES' write-off of its goodwill. Income tax expense increased for the three and six months endedJune 30, 2021 , compared to the same periods in 2020, primarily due to higher crude oil, NGL and natural gas prices.

SEGMENT RESULTS OF OPERATIONS AND ITEMS AFFECTING COMPARABILITY
SEGMENT RESULTS OF OPERATIONS Occidental's principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil and condensate, NGL and natural gas. The chemical segment mainly manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil, condensate, NGL, natural gas, CO2 and power. It also trades around its assets, including transportation and storage capacity, and invests in entities that conduct similar activities such as WES. The following table sets forth the sales and earnings of each operating segment and corporate items for the three and six months endedJune 30, 2021 and 2020: Three months ended June 30, Six months ended June 30, millions 2021 2020 2021 2020 Net sales (a) Oil and gas$ 4,505 $ 2,040 $ 8,169 $ 7,100 Chemical 1,187 846 2,275 1,808 Midstream and marketing 497 204 1,304 994 Eliminations (231) (162) (497) (361) Total 5,958 2,928 11,251 9,541 Income (loss) from continuing operations Oil and gas (b) 631 (7,734) 569 (7,498) Chemical 312 108 563 294 Midstream and marketing (b) (30) (7) 252 (1,294) Total 913 (7,633) 1,384 (8,498) Unallocated corporate items Interest expense, net (385) (310) (780) (662) Income tax benefit (expense) (b) (43) 1,468 (59) 1,493 Other items, net (b) (385) (241) (146) (1,062) Income (loss) from continuing operations $ 100$ (6,716) $ 399 $ (8,729) (a) Intersegment sales eliminate upon consolidation and are generally made at prices approximating those that the selling entity would be able to obtain in third-party transactions.

Excluding the impact of asset impairments and other charges and oil, gas and CO2 derivative gains (losses), oil and gas segment results for the three and six months endedJune 30, 2021 , compared to the same periods in 2020, reflected higher commodity prices, partially offset by lower sales volumes and higher DD&A rates. The following table sets forth the average sales volumes per day for oil in thousands of barrels (Mbbl), for NGL in thousands of barrels equivalent (Mboe) and for natural gas in millions of cubic feet (MMcf): Three months ended June 30, Six months ended June 30, 2021 2020 2021 2020 Sales Volumes per Day Oil (Mbbl) United States 517 603 502 633 International 118 136 116 134 NGL (Mboe) United States 224 230 212 230 International 36 39 32 37 Natural Gas (MMcf) United States 1,322 1,697 1,306 1,696 International 501 571 457 552

(b) Natural gas volumes have been converted to barrels of oil equivalent (Boe) based on energy content of six Mcf of gas to one barrel of oil. Barrels of oil equivalent does not necessarily result in price equivalency. Average daily sales volumes from continuing operations were 1,199 Mboe per day (Mboe/d) for the three months endedJune 30, 2021 , compared to 1,386 Mboe/d for the same period in 2020. The decrease in average daily sales volumes from continuing operations of 187 Mboe/d for the three months endedJune 30, 2021 , compared to the same period in 2020, primarily reflected declines in the Permian and DJ Basins as a result of reduced capital investment. Total average daily sales volumes from continuing operations for the first six months of 2021 and 2020 were 1,156 Mboe/d and 1,409 Mboe/d, respectively. The decrease in average daily sales volumes from continuing operations of 253 Mboe/d for the six months endedJune 30, 2021 , compared to the same period in 2020, primarily reflected declines in the Permian and DJ Basins as a result of reduced capital investment. 30 -------------------------------------------------------------------------------- The following table presents information about Occidental's average realized prices and index prices: Three months ended June 30, Six months ended June 30, 2021 2020 2021 2020 Average Realized Prices (a) Oil ($/Bbl) United States $ 64.39$ 21.27 $ 60.43$ 34.07 International $ 63.26$ 31.42 $ 58.44$ 42.16 Total Worldwide $ 64.18$ 23.14 $ 60.05$ 35.48 NGL ($/Boe) United States $ 25.33 $ 7.22 $ 24.53 $ 9.60 International $ 23.36$ 11.23 $ 22.84$ 15.58 Total Worldwide $ 25.06 $ 7.79 $ 24.31$ 10.43 Natural Gas ($/Mcf) United States $ 2.59 $ 0.90 $ 2.58 $ 1.04 International $ 1.68 $ 1.67 $ 1.69 $ 1.70 Total Worldwide $ 2.34 $ 1.10 $ 2.35 $ 1.20 Average Index Prices WTI oil ($/Bbl) $ 66.07$ 27.85 $ 61.96$ 37.01 Brent oil ($/Bbl) $ 69.02$ 33.26 $ 65.06$ 42.11 NYMEX gas ($/Mcf) $ 2.76 $ 1.77 $ 2.74 $ 1.91 Average Realized Prices as Percentage of Average Index Prices Worldwide oil as a percentage of average WTI 97 % 83 % 97 % 96 % Worldwide oil as a percentage of average Brent 93 % 70 % 92 % 84 % Worldwide NGL as a percentage of average WTI 38 % 28 % 39 % 28 % Domestic natural gas as a percentage of average NYMEX 94 % 51 % 94 % 54 % (a) For the three months endedJune 30, 2020 , average realized prices decreased relative to indexed prices due to price volatilities as a result of the COVID-19 pandemic, which decreased demand resulting in significant declines in regional oil prices especially in the Permian and DJ Basins. CHEMICAL SEGMENT Chemical segment earnings for the three and six months endedJune 30, 2021 were$312 million and$563 million , respectively, compared to$108 million and$294 million for the same periods in 2020, respectively. Compared to the same periods in 2020, the three and six months endedJune 30, 2021 reflected improved prices across most products, partially offset by higher ethylene and energy costs. MIDSTREAM AND MARKETING SEGMENT Midstream and marketing segment results for the three and six months endedJune 30, 2021 were a loss of$30 million and income of$252 million , respectively, compared to losses of$7 million and$1.3 billion for the same periods in 2020, respectively. Excluding the impact of impairment charges, net derivative mark-to-market gains and losses and asset sale gains and losses, the increase in midstream and marketing segment results for the three and six months endedJune 30, 2021 , compared to the same period in 2020, reflected optimization of natural gas transportation and higher sulfur prices atAl Hosn Gas . The results for the six months ended June 30 2021 also included higher gas margins from the marketing business' ability to optimize long-haul gas transportation during the first three months of 2021. 31 --------------------------------------------------------------------------------
INCOME TAXES
The following table sets forth the calculation of the worldwide effective tax rate for income from continuing operations:
Three months ended June 30, Six months ended June 30, millions, except percentages 2021 2020 2021 2020 Income (loss) from continuing operations before income taxes$ 143 $ (8,184) $ 458 $ (10,222) Income tax benefit (expense) Domestic - federal and state 8 1,577 110 1,667 International (51) (109) (169) (174) Total income tax benefit (expense) (43) 1,468 (59) 1,493
Income (loss) from continuing operations
30% 18% 13% 15% Occidental estimates its annual effective income tax rate in recording its quarterly provision for income taxes in the various jurisdictions in which Occidental operates, adjusted for certain discrete items. Each quarter, Occidental updates these rates and records a cumulative adjustment to its income taxes by applying the rates to the pre-tax income excluding certain discrete items. Occidental's quarterly estimate of its effective tax rates can vary significantly based on various forecasted items, including future commodity prices, capital expenditures, expenses for which tax benefits are not recognized and the geographic mix of pre-tax income and losses. The difference between the 30% and 13% effective tax rates for income from continuing operations for the three and six months endedJune 30, 2021 , and the 21%U.S. federal statutory tax rate is primarily driven by the jurisdictional mix of income.U.S. income is taxed at aU.S. federal statutory rate of 21%, while international income is subject to tax at statutory rates as high as 55%. In addition, the effective tax rate was impacted by a state margin tax rate reduction and one-time benefits associated with the settlement of federal and state audit matters.
LIQUIDITY AND CAPITAL RESOURCES
AtJune 30, 2021 , Occidental had$4.6 billion in cash and cash equivalents and$180 million in restricted cash and restricted cash equivalents classified as current assets. Operating cash flow from continuing operations was$4.1 billion for the six months endedJune 30, 2021 , compared to$1.7 billion for the same period in 2020. The increase in operating cash flow from continuing operations was primarily due to higher commodity prices during the first half of 2021 as compared to the same period in 2020. This increase was partially offset by an increase in working capital related to receivables, which increased largely as a result of the improvement in prices. Occidental's net cash used by investing activities from continuing operations was$1.0 billion for the six months endedJune 30, 2021 , compared to$2.1 billion for the same period in 2020. Capital expenditures for the six months endedJune 30, 2021 and 2020 were approximately$1.3 billion and$1.7 billion , respectively, of which substantially all were for the oil and gas segment. For the six months endedJune 30, 2021 , proceeds from sales of equity investments and other assets, net primarily included the divestiture of non-operated assets in theDJ Basin as well as the sale of WES units. Occidental's net cash used by financing activities from continuing operations was$0.6 billion for the six months endedJune 30, 2021 , compared to approximately$2.0 billion for the same period in 2020. Cash used by financing activities for the six months endedJune 30, 2021 reflected the dividend payments of$420 million on preferred and common stock and payments on current maturities of long-term debt of$174 million . As ofJune 30, 2021 , and as of the date of this filing, Occidental was in compliance with all covenants in its financing agreements. Occidental currently expects its cash on hand and funds available under its RCF to be sufficient to meet its near-term debt maturities, operating expenditures and other obligations for the next 12 months from the date of this filing. For information regarding upcoming debt maturities and other near-term obligations, see the Current Business Outlook section of the Management's Discussion and Analysis of Financial Condition and Results of Operations. 32 --------------------------------------------------------------------------------
ENVIRONMENTAL LIABILITIES AND EXPENDITURES
Occidental's operations are subject to stringent federal, regional, state, provincial, tribal, local and international laws and regulations related to improving or maintaining environmental quality. Occidental's environmental compliance costs have generally increased over time and are expected to rise in the future. Occidental factors environmental expenditures for its operations as an integral part of its business planning process. The laws that require or address environmental remediation, including CERCLA and similar federal, regional, state, provincial, tribal, local and international laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. Occidental or certain of its subsidiaries participate in or actively monitor a range of remedial activities and government or private proceedings under these laws with respect to alleged past practices at operating, closed and third-party sites. Remedial activities may include one or more of the following: investigation involving sampling, modeling, risk assessment or monitoring; cleanup measures including removal, treatment or disposal; or operation and maintenance of remedial systems. The environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, punitive damages, civil penalties, injunctive relief and government oversight costs. See Note 9 - Environmental Liabilities and Expenditures in the notes to the consolidated condensed financial statements in Part I, Item 1 of this Form 10-Q and the Environmental Liabilities and Expenditures section of Management's Discussion and Analysis of Financial Condition and Results of Operations in the 2020 Form 10-K for additional information regarding Occidental's environmental liabilities and expenditures.
