UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA

Exhibit 99.3

On May 9, 2019, Occidental Petroleum Corporation (“Occidental”) and Anadarko Petroleum Corporation (“Anadarko”) entered into an Agreement and Plan of Merger (the “merger agreement”), which provides that, upon the terms and subject to the conditions set forth therein, Baseball Merger Sub 1, Inc., an indirect wholly owned subsidiary of Occidental (“Merger Subsidiary”), will merge with and into Anadarko (the “merger”), with Anadarko continuing as the surviving corporation and an indirect wholly owned subsidiary of Occidental. If the merger is completed, Anadarko stockholders will receive, in exchange for each share of Anadarko common stock, par value $0.10 per share (“Anadarko common stock”), (1) $59.00 in cash and (2) 0.2934 of a share of Occidental common stock, par value $0.20 per share (“Occidental common stock”), in each case, subject to limited adjustments as set forth in the merger agreement.

On April 30, 2019, Occidental entered into a Securities Purchase Agreement with Berkshire Hathaway Inc. (“Berkshire Hathaway”) pursuant to which, subject to the terms and conditions set forth therein, including completion of the merger, Occidental agreed to issue and sell to Berkshire Hathaway, and Berkshire Hathaway agreed to purchase from Occidental for an aggregate purchase price of $10 billion in cash (the “Berkshire Hathaway investment”): (1) 100,000 shares of a new series of cumulative perpetual preferred stock of Occidental, having a face value of $100,000 per share (the “series A preferred stock”), and (2) a warrant to purchase 80.0 million shares of Occidental’s common stock at an exercise price of $62.50 per share. Dividends on the series A preferred stock will accrue on the face value at a rate per annum of 8% but will be paid only when, as and if declared by Occidental’s Board of Directors out of legally available funds.

In connection with the merger, Occidental and TOTAL S.A. (“Total”) entered into a binding memorandum of understanding, dated May 3, 2019, pursuant to which Occidental has agreed to sell to Total all of the assets, liabilities, businesses and operations of Anadarko in Algeria, Ghana, Mozambique and South Africa for $8.8 billion in cash, on a cash-free, debt-free basis (the “Total transaction”). The Total transaction is conditioned on the completion of the merger, the execution and delivery of a definitive purchase agreement, and the receipt of required regulatory approvals, as well as other customary closing conditions.

On June 3, 2019, Occidental entered into an $8.8 billion term loan credit agreement (the “term loan credit agreement”) with Citibank, N.A., as administrative agent, and certain financial institutions party thereto, as lenders (the “term loan lenders”), pursuant to which, subject to the terms and conditions set forth therein, including completion of the merger, the term loan lenders committed to provide (i) a 364-day senior unsecured term loan facility in an aggregate principal amount of up to $4.4 billion and (ii) a two-year senior unsecured term loan facility in an aggregate principal amount of up to $4.4 billion, the proceeds of which will be used to partially finance the merger and pay related fees and expenses.

Also in connection with the merger, Occidental has obtained commitments (the “bridge loan commitments”) from certain financial institutions to provide, subject to completion of the merger and other customary conditions, a 364-day senior unsecured bridge loan facility in an aggregate principal amount of up to $13.0 billion. Such commitments will be reduced to the extent that Occidental obtains certain other debt financing or debt financing commitments, completes certain issuances of equity, equity-linked or hybrid debt-equity securities or completes certain asset sales (subject to customary reinvestment rights).

The unaudited pro forma condensed combined financial statements (the “pro forma financial statements”) presented below have been prepared from the respective historical consolidated financial statements of Occidental and Anadarko and have been adjusted to reflect (i) the completion of the merger, (ii) Occidental’s incurrence of $21.8 billion of new indebtedness to finance a portion of the cash merger consideration, (iii) the Berkshire Hathaway investment and (iv) the Total transaction (collectively, the “transactions”). The unaudited pro forma condensed combined balance sheet (the “pro forma balance sheet”) is presented as if the transactions had been completed on June 30, 2019. The unaudited pro forma combined statements of operations (the “pro forma statements of operations”) for the year ended December 31, 2018, and for the six months ended June 30, 2019, are presented as if the transactions had been completed on January 1, 2018.

The pro forma financial statements have been prepared from, and should be read in conjunction with, (i) the unaudited consolidated financial statements of Occidental contained in its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2019, (ii) the unaudited consolidated financial statements of Anadarko contained in its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2019, (iii) the audited consolidated financial statements of Occidental contained in its Annual Report on Form 10-K for the year ended December 31, 2018, (iv) the audited consolidated financial statements of Anadarko contained in its Annual Report on Form 10-K for the year ended December 31, 2018 and (v) Anadarko’s Form 8-K filed on May 15, 2019 in order to recast the segment information included in Anadarko’s Annual Report on Form 10-K for the year ended December 31, 2018, following a change in its reportable segments during the three months ended March 31, 2019. Certain of Anadarko’s historical amounts have been reclassified to conform to Occidental’s financial statement presentation.

The pro forma financial statements have been prepared to reflect adjustments to Occidental’s historical consolidated financial information that are (i) directly attributable to the merger, (ii) factually supportable and (iii) with respect to the statements of operations only, expected to have a continuing impact on Occidental’s results.

The pro forma financial statements reflect the following pro forma adjustments, based on available information and certain assumptions that Occidental believes are reasonable:

•

The merger contemplated by the merger agreement under the acquisition method of accounting;

•

the assumed conversion of each share of Anadarko common stock into $59.00 in cash (without interest) and 0.2934 of a share of Occidental common stock in accordance with the merger agreement;

•

the conversion of Anadarko’s outstanding stock-based awards into Occidental stock-based awards, merger consideration and/or cash in accordance with the merger agreement;

•

the assumption of liabilities for expenses related to the transactions;

•

the incurrence by Occidental of $21.8 billion of new indebtedness to finance a portion of the cash merger consideration, consisting of (i) $8.8 billion in term loans incurred under the term loan credit agreement, with maturities of 364 days and two years, and (ii) $13.0 billion in long-term debt issued or incurred in lieu of borrowings pursuant to, and which would reduce to $0 the bridge loan commitments, with maturities of up to thirty years;

•

the issuance and sale by Occidental pursuant to the Berkshire Hathaway investment of 100,000 shares of series A preferred stock and a warrant to acquire 80,000,000 shares of Occidental common stock for an aggregate purchase price of $10 billion; and

•

the sale of Anadarko’s assets, liabilities, businesses and operations in Algeria, Ghana, Mozambique and South Africa to Total for $8.0 billion, net of a transfer tax liability of $0.8 billion, on a cash-free, debt-free basis pursuant to the Total transaction, presented initially as held for sale for preliminary purchase price allocations, and the use of proceeds therefrom to pay down indebtedness.

The pro forma financial statements do not include the realization of cost savings from operating efficiencies, revenue synergies or other integration costs expected to result from the merger.

The pro forma financial statements have been prepared using the acquisition method of accounting using the accounting guidance in Accounting Standards Codification 805, Business Combinations (“ASC 805”), with Occidental treated as the acquirer. The acquisition method of accounting is dependent upon certain valuations and other studies that, as of the date hereof, have yet to commence or progress to a stage where there is sufficient information for a definitive measure. As indicated in the pro forma financial statements and under “Estimated Purchase Price and Allocation” below, Occidental has performed a preliminary valuation analysis of the fair value of Anadarko’s assets to be acquired and liabilities to be assumed and has made certain adjustments to the historical book values of the assets and liabilities of Anadarko to reflect preliminary estimates of the fair values necessary to prepare the pro forma financial statements, with the excess of the purchase price over the adjusted historical net assets of Anadarko recorded as goodwill. Occidental will perform a detailed review of Anadarko’s accounting policies in connection with the completion of the merger and, as of the date hereof, has not yet identified all adjustments, if any, necessary to conform Anadarko’s financial records to Occidental’s accounting policies. Accordingly, the pro forma financial statements and pro forma adjustments are preliminary and have been made solely for the purpose of providing the pro forma financial statements. Amounts used in these pro forma financial statements will differ from ultimate amounts once Occidental has determined the final allocation of the purchase price and has completed the valuation studies necessary to finalize the required purchase price allocations and identified any necessary conforming accounting policy changes for Anadarko. Differences between these preliminary estimates and the final acquisition accounting may have a material impact on the pro forma financial statements and the combined company’s future results of operations and financial position.

The pro forma financial statements are provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or consolidated financial position of Occidental would have been had the transactions occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position. This unaudited pro forma condensed combined financial data is presented for illustrative purposes only and the actual financial condition and results of operations of Occidental following the completion of the merger may differ materially.

The pro forma financial statements and related notes should be read in conjunction with the separate historical consolidated financial statements and related notes of each of Occidental and Anadarko included in their respective Annual Reports on Form 10-K for the fiscal year ended December 31, 2018 and Quarterly Reports on Form 10-Q for the quarter ended June 30, 2019.

Estimated Purchase Price and Allocation

The estimated aggregate value of the purchase price is approximately $37.2 billion based on the closing price of Occidental common stock of $51.59 on July 26, 2019, the last practicable trading date prior to the date hereof, and assuming an exchange ratio of 0.2934 of a share of Occidental common stock per share of Anadarko common stock. The value of the purchase price will fluctuate based upon changes in the share price of Occidental’s common stock and the number of Anadarko’s common shares, stock options and other stock-based awards outstanding on the closing date. In addition, the exchange ratio may be decreased, and the cash portion of the merger consideration may be increased, in certain limited circumstances described in the merger agreement.

Estimated Purchase Price

The following table summarizes the estimated common stock outstanding including shares underlying Anadarko stock-based awards and the components of the estimated purchase price:

in millions of dollars and shares, except for per share amounts and exchange ratio*	Total shares outstanding
Estimated shares of Anadarko common stock outstanding		502.4
Plus: estimated shares underlying Anadarko stock-based awards		1.6
		504.0
Less: estimated shares underlying Anadarko stock-based awards - unvested		(3.8	)
Total shares of common stock and shares underlying Anadarko stock-based awards eligible for merger consideration**		500.2

Total shares of common stock and shares underlying Anadarko stock-based awards eligible for merger consideration		500.2
Cash consideration (per share of common stock and shares underlying Anadarko stock-based awards eligible for merger consideration)	$	59.00
Estimated cash portion of aggregate merger consideration	$	29,510
Estimated cash paid to settle shares underlying Anadarko stock-based awards per the merger agreement***	$	133
Cash portion of estimated purchase price	$	29,643

Total shares of common stock and shares underlying Anadarko stock-based awards eligible for merger consideration		500.2
Exchange ratio (per share of Anadarko common stock)		0.2934
Estimated total shares of Occidental common stock to be issued		146.8
Assumed share price of Occidental common stock	$	51.59
Stock portion of estimated purchase price	$	7,571
Total estimated purchase price	$	37,214

*	The final purchase price per share and corresponding total consideration will be determined on the closing date of the merger.

**	Includes vested Anadarko RSU awards and Anadarko RS awards.

***	The estimated cash payable to settle shares underlying Anadarko stock-based awards per the merger agreement is based on the amounts attributable to pre-merger service.

Occidental anticipates incurring approximately $21.8 billion of new indebtedness and issuing the series A preferred stock and a warrant to acquire Occidental common stock for an aggregate purchase price of $10 billion pursuant to the Berkshire Hathaway investment to finance a portion of the cash purchase price.

Purchase Price Sensitivity

The table below illustrates the potential impact to the total estimated purchase price resulting from a 10% increase or decrease in the assumed share price of Occidental’s common stock of $51.59. For purposes of this calculation, the stock portion of the estimated purchase price is based on the number of shares of Anadarko common stock outstanding and the estimated shares underlying Anadarko stock-based awards, in each case reflected in the table above, but is subject to change based on the actual outstanding shares of Anadarko common stock and Anadarko stock based awards at the time of the closing of the merger.

in millions	10% increase in Occidental share price		10% decrease in Occidental share price
Cash portion of estimated purchase price	$	29,643	$	29,643
Stock portion of estimated purchase price		8,328		6,814
Total estimated purchase price	$	37,971	$	36,457

From May 3, 2019, the last trading day before the public announcement of Occidental’s final proposal to acquire Anadarko, to July 26, 2019, the last practicable trading day prior to the date hereof, the preliminary value of the purchase price to be transferred decreased by approximately $930 million, as a result of the decrease in the share price for Occidental’s common stock from $57.95 to $51.59. Changes in the purchase price would result in a re-evaluation of the preliminary purchase price allocation; specifically to the values determined for property, plant and equipment, intangibles and goodwill.

Preliminary Purchase Price Allocation

The preliminary allocation of the estimated purchase price to the fair values of assets acquired and liabilities assumed includes pro forma adjustments for the fair value of Anadarko’s assets and liabilities. The final allocation will be determined as of the closing of the merger once Occidental has determined the final purchase price and completed the detailed valuation analysis and calculations necessary to finalize the required purchase price allocations. The final allocation could differ materially from the preliminary allocation used in these pro forma financial statements and related pro forma adjustments.

Occidental has performed a preliminary valuation analysis of the fair market value of the Anadarko assets to be acquired and liabilities to be assumed and the related allocations to such items of the estimated purchase price. The following table summarizes the allocation of the preliminary estimated purchase price:

in millions	As of June 30, 2019
Fair value of assets acquired:
Cash			$	1,352
Current held for sale assets related to Anadarko’s Africa assets	$	810
Property, plant and equipment held for sale related to Anadarko’s Africa assets		9,132
Total assets held for sale¹	$	9,942		9,942

Trade receivables, net				1,498
Inventories				541
Other current assets				72
Executives and Directors Benefits Trust				482
Investment in unconsolidated entities				1,407
Property, plant and equipment attributable to Anadarko, excluding WES				49,295
Property, plant and equipment attributable to WES				10,500
Operating lease assets				481
Intangible assets				3,184
Long-term receivables and other assets, net				263
Amount attributable to assets acquired				79,017

Fair value of liabilities assumed:
Current liabilities			$	3,327
Current held for sale liabilities related to Anadarko’s Africa liabilities	$	1,142
Fair value adjustment for Anadarko’s Africa liabilities held for sale		800
Liabilities held for sale¹	$	1,942		1,942

Debt attributable to Anadarko, excluding WES				12,767
Debt attributable to WES				7,502
Deferred income taxes, net				9,562
Asset retirement obligations				2,721
Other long term liabilities				4,208
Amount attributable to liabilities assumed			$	42,029

Fair value of noncontrolling interests in WES²:			$	5,659

Fair value of net assets acquired:			$	31,329
Goodwill as of June 30, 2019:			$	5,885
Total Purchase Price:			$	37,214

¹	Anadarko’s liabilities, businesses and operations in Algeria, Ghana, Mozambique, and South Africa held for sale pursuant to the Total transaction (“Anadarko’s Africa assets” or “Anadarko’s Africa liabilities”, as applicable) totals to $8.0 billion, net of a transfer tax liability of $0.8 billion.

Noncontrolling interests associated with Anadarko’s consolidated subsidiary, Western Midstream Partners, LP (“WES”), a publicly traded limited partnership. Net assets acquired from WES were valued using a share price of $27.00, fluctuations in the share price could result in changes to the net assets and noncontrolling interests above.

The preliminary pro forma fair value of crude oil and natural gas properties to be acquired includes the following:

in millions	As of June 30, 2019
Proved properties	$	19,227
Unproved properties		28,271
Pro forma fair value of properties acquired	$	47,498

Changes in future commodity prices, reserve estimates, other changes in cost assumptions and other facts and circumstances existing on the closing date of the merger compared to the date of these pro forma financial statements could result in changes to the fair value of the assets identified above.

Occidental estimated the fair value adjustment to increase Anadarko’s consolidated debt to fair value would be $2.3 billion based on prevailing market prices. Occidental has estimated that the fair value adjustment to increase deferred tax liabilities, net would be $7.3 billion, relating to estimated fair value adjustments at the estimated statutory tax rate for the combined company. Goodwill is calculated as the difference between the acquisition date fair value of the consideration expected to be transferred and the values assigned to the identified assets to be acquired and liabilities assumed. Goodwill is not amortized, but rather is subject to impairment testing on at least an annual basis.

Total assets held for sale and liabilities held for sale represent the anticipated divestiture of Anadarko’s Africa assets in the Total transaction for $8.0 billion, net of a transfer tax liability of $0.8 billion. The Total transaction is conditioned on the completion of the merger, the execution and delivery of a definitive purchase agreement, and the receipt of required regulatory approvals, as well as other customary closing conditions.

Reflects the proceeds of $10 billion related to the issuance pursuant to the Berkshire Hathaway investment of 100,000 shares of series A preferred stock (par value $1.00), and a warrant (the “warrant”) to purchase 80 million shares of Occidental common stock at an exercise price of $62.50. In the second quarter of 2019 Occidental paid $50 million in preferred share issuance costs. Of the net proceeds, $9.519 billion was allocated to the issuance of the series A preferred stock, which is reflected in additional paid-in capital, and $431 million was allocated to the warrant liability classified in other liabilities. The warrant will be remeasured at fair value each reporting period with the adjustment flowing through earnings.

e)	Reflects the fair value adjustments to Anadarko’s property, plant and equipment, intangible assets, held for sale assets and liabilities related to Anadarko’s Africa assets and other assets and liabilities, including debt and goodwill. See “Estimated Purchase Price and Allocation” above.

f)	Represents pro forma adjustments to current and long-term debt, which includes:

Issuance of $21.8 billion of new indebtedness, with an estimated average annual interest rate of 4.3%, yielding net proceeds of $4.4 billion and $17.3 billion in short- and long-term debt, respectively. Anticipated proceeds are net of $111 million in debt issuance costs. After giving effect to the pay down of $8.8 billion in aggregate principal amount of term loans with the proceeds from the anticipated divestiture and other sources, the estimated average annual interest rate of the remaining $13.0 billion of new indebtedness is 4.6%. Estimated interest rates are based on underlying U.S. Treasury rates adjusted for Occidental’s anticipated credit spreads across a range of maturities.

ii.

After giving effect to the pay down of $8.8 billion in aggregate principal amount of term loans, the associated pro forma interest expense and amortization on the remaining $13.0 billion of new indebtedness is approximately $308 million and $617 million for the six months ended June 30, 2019 and for the year ended December 31, 2018, respectively. A one percent change in the assumed interest rate of the $13.0 billion in new indebtedness would increase or decrease the interest expense by $65 million and $130 million for the six months ended June 30, 2019 and for the year ended December 31, 2018, respectively. In the event the $8.8 billion of term loans are not repaid and remain outstanding, pro forma interest expense would increase by approximately $168 million and $336 million for the six months ended June 30, 2019 and for the year ended December 31, 2018, respectively.

iii.

Fair value adjustment of $2.3 billion to historical Anadarko debt results in additional debt discount amortization of $43 million and $86 million for the six months ended June 30, 2019 and for the year ended December 31, 2018, respectively.

iv.

The six months ended June 30, 2019 excludes nonrecurring amortization expense of $57 million related to Occidental historical results. The remaining $50 million will be expensed in the third quarter of 2019 and is presented as a charge to retained earnings in the balance sheet as of June 30, 2019.

g)	Represents an adjustment to deferred tax liabilities, net based on the estimated statutory tax rate for the combined entity multiplied by the fair value adjustments made to assets and liabilities acquired, calculated below:

in millions	As of June 30, 2019
Fair value of Anadarko property, plant and equipment excluding Anadarko’s Africa assets	$	49,295
Less: Anadarko historical value property, plant and equipment excluding Anadarko’s Africa assets		(17,656	)

Less: Anadarko historical debt, excluding WES debt		(10,523	)
Fair value adjustment to Anadarko debt, excluding WES debt, assumed by Occidental	$	2,244
Fair value adjustment for WES debt		13
Fair value adjustment to increase debt per Note (e)	$	2,257

(1) For additional information regarding the assumed transfer tax liability associated with Xxxxxxxx’s Africa assets, see “-Preliminary Purchase Price Allocation” above.

in millions	As of June 30, 2019
Fair value adjustment to increase Anadarko property, plant and equipment, net of Anadarko’s Africa assets	$	31,639
Fair value adjustment to increase WES property, plant and equipment and intangibles		2,242
Fair value adjustment to Xxxxxxxx’s debt, excluding WES debt, assumed by Occidental ⁽²⁾		(2,244	)
	$	31,637
Estimated statutory domestic tax rate for the combined entity		23	%
	$	7,276

(2) Excludes fair value adjustment to WES debt of $13 million because the impact to deferred tax liabilities net of noncontrolling interests and the estimated statutory domestic tax rate was immaterial.

h)	Reflects adjustments to eliminate Xxxxxxxx’s historical equity balances and record estimated purchase price at fair value:

Fair value of noncontrolling interests	$	5,659
Elimination of Anadarko historical noncontrolling interests		(1,558	)
Pro forma adjustment to noncontrolling interests	$	4,101

i)	The following pro forma adjustments eliminate historical transactions between Anadarko and Occidental that would be treated as intercompany transactions after the merger:

Elimination of $5 million in net sales and corresponding cost of sales in the pro forma statement of operations for the six months ended June 30, 2019.

ii.

Elimination of $2 million in net sales and corresponding cost of sales in the pro forma statement of operations for the year ended December 31, 2018.

Reflects adjustments to income and expense as a result of purchase accounting, including historical depreciation, depletion and amortization (“DD&A”) expense related to the step up of property, plant and equipment to estimated fair value. Pro forma DD&A expense related to the assets acquired through the merger, excluding Anadarko’s Africa assets, is $2.2 billion and $4.0 billion for the six months ended June 30, 2019 and for the year ended December 31, 2018, respectively. In addition, reflects the removal of nonrecurring acquisition costs of $1.1 billion, primarily related to the Chevron termination fee incurred by Anadarko in the second quarter of 2019.

Reflects the elimination of Xxxxxxxx’s weighted-average shares outstanding and the issuance of Occidental common stock to Anadarko stockholders as part of the stock portion of the purchase price. The effect of the issuance of the warrant has been included in diluted shares. Basic and Diluted earnings per share have been reduced by $400 million and $800 million for the six months ended June 30, 2019 and the year ended December 31, 2018, respectively, for pro forma dividends on the series A preferred stock.

Standardized measure of discounted future net cash flows

The following tables present the estimated pro forma discounted future net cash flows at December 31, 2018. The pro forma standardized measure information set forth below gives effect to the transactions as if the transactions had been completed on January 1, 2018. The disclosures below were determined by referencing the “Standardized Measure of Discounted Future Net Cash Flows” reported in Anadarko’s and Occidental’s respective Annual Reports on Form 10-K for the year ended December 31, 2018; an explanation of the underlying methodology applied, as required by SEC regulations, can be found within the applicable Annual Report on Form 10-K. The calculations assume the continuation of existing economic, operating and contractual conditions at December 31, 2018. Therefore, the following estimated pro forma standardized measure is not necessarily indicative of the results that might have occurred had the transactions been completed on January 1, 2018 and is not intended to be a projection of future results. Future results may vary significantly from the results reflected because of various factors.

Therefore, the following estimated pro forma standardized measure is not necessarily indicative of the results that might have occurred had the transactions been completed on January 1, 2018 and is not intended to be a projection of future results.
