Note 1 : Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements (unaudited) and notes to the consolidated financial statements (unaudited) are presented in accordance with the rules and regulations of the Securities and Exchange Commission and do not include all the disclosures normally required in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). During the first quarter of fiscal year 2018, the Company conformed the financial reporting calendar of a subsidiary, which did not have a significant effect on the consolidated financial statements. The consolidated financial statements (unaudited), in the opinion of management, contain all adjustments necessary to present fairly the financial position as of May 4, 2018 , and May 5, 2017 , and the results of operations and comprehensive income for the three months ended May 4, 2018 , and May 5, 2017 , and cash flows for the  three months ended May 4, 2018  and  May 5, 2017 .

These interim consolidated financial statements (unaudited) should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Lowe's Companies, Inc. (the Company) Annual Report on Form 10-K for the fiscal year ended February 2, 2018 (the Annual Report). The financial results for the interim periods may not be indicative of the financial results for the entire fiscal year.

Accounting Pronouncements Recently Adopted

Effective February 3, 2018, the Company adopted Accounting Standards Update 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606) , and all the related amendments, using the modified retrospective method. ASU 2014-09 requires a company to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Upon adoption of ASU 2014-09, the Company recorded an immaterial adjustment to the opening balance of retained earnings as of February 3, 2018, with related adjustments to deferred revenue, accounts payable and related tax effects. The adjustment to retained earnings primarily relates to the change in revenue recognition related to gift card breakage. The adoption of the guidance also required a change in the timing of how installation services are recognized, the presentation of sales return reserve on the consolidated balance sheet, and a change in the presentation of the Company's profit sharing income from its proprietary credit program. We applied ASU 2014-09 only to contracts that were not completed prior to fiscal 2018. Results for reporting periods beginning after February 2, 2018 are presented under ASU 2014-09, while comparative prior period amounts have not been restated and continue to be presented under accounting standards in effect in those periods. See Note 2 for additional details of the Company's revenues.

The impact of adopting the new revenue recognition guidance on our consolidated statement of earnings is as follows:

The impacts of adopting the new revenue recognition guidance to assets and liabilities on our consolidated balance sheets are as follows:

Accounting Pronouncements Not Yet Adopted

In January 2017, the Financial Accounting Standards Board (FASB) issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350) . The ASU eliminates Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation to the identified assets and liabilities of the reporting unit to measure goodwill impairment. Under the amendments in this update, a goodwill impairment test is performed by comparing the fair value of the reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The adoption of this guidance by the Company is not expected to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The guidance in this ASU supersedes the leasing guidance in Topic 840, Leases . Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for those leases previously classified as operating leases. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements but expects the ASU to have a material impact on its consolidated balance sheets, as a result of the requirement to recognize right-of-use assets and lease liabilities.

Note 2 : Net Sales

Net sales consists primarily of revenue, net of sales tax, associated with contracts with customers for the sale of goods and services in amounts that reflect consideration the Company is entitled to in exchange for those goods and services.

The following table presents the Company's sources of revenue:

Revenue from products primarily relates to in-store and online merchandise purchases, which are recognized at the point in time when the customer obtains control of the merchandise, which is at the time of in-store purchase or delivery of the product to the customer. A provision for anticipated merchandise returns is provided through a reduction of sales and cost of sales in the period that the related sales are recorded.  Under ASU 2014-09, the merchandise return reserve is presented on a gross basis, with a separate asset and liability included in the consolidated balance sheets as of reporting periods after February 2, 2018 . Reporting periods prior to the adoption of ASU 2014-09 reflect merchandise return reserves on a net basis. As of May 4, 2018 , anticipated sales returns of $305 million are reflected in other current liabilities, and the associated right of return assets of $197 million are reflected in other current assets. As of May 5, 2017 , the merchandise return reserve, net of the associated asset, was $101 million reflected in other current liabilities.

Revenues from services primarily relate to professional installation services the Company provides through subcontractors related to merchandise purchased by a customer. In certain instances, installation services include materials provided by the subcontractor, and both product and installation are included in service revenue. The Company recognizes revenue associated with services as they are rendered, and the majority of services are completed within one week from initiation.

Deferred revenue is presented for merchandise that has not yet transferred control to the customer and for services that have not yet been provided, but for which tender has been accepted. Deferred revenue is recognized in sales either at a point in time when the customer obtains control of merchandise through pickup or delivery, or over time as services are provided to the customer. Deferred revenues associated with amounts received for which customers have not taken possession of the merchandise or for which installation has not yet been completed were  $1.0 billion  and  $967 million  at  May 4, 2018 and May 5, 2017 , respectively. The majority of revenue for goods and services is recognized in the quarter following revenue deferral.

Stored-value cards

In addition, the Company defers revenues from stored-value cards, which include gift cards and returned merchandise credits, and recognizes revenue into sales when the cards are redeemed.  The liability associated with outstanding stored-value cards was  $437 million  and  $449 million  at  May 4, 2018 , and  May 5, 2017 , respectively, and these amounts are included in deferred revenue on the consolidated balance sheets. Upon adoption of ASU 2014-09, the Company recognizes income from unredeemed stored-value cards in proportion to the pattern of rights exercised by the customer. Amounts recognized as breakage were insignificant for the three months ended May 4, 2018 and May 5, 2017 .

Extended protection plans

The Company also defers revenues for its separately-priced extended protection plan contracts, which is a Lowe's-branded program for which the Company is ultimately self-insured.  The Company recognizes revenue from extended protection plan sales on a straight-line basis over the respective contract term.  Extended protection plan contract terms primarily range from one to five years from the date of purchase or the end of the manufacturer's warranty, as applicable. Deferred revenue from extended protection plans recognized into sales were insignificant for the three months ending May 4, 2018 and May 5, 2017. Incremental direct acquisition costs associated with the sale of extended protection plans are also deferred and recognized as expense on a straight-line basis over the respective contract term and were insignificant at May 4, 2018 and May 5, 2017, respectively.  The Company's extended protection plan deferred costs are included in other assets (noncurrent) on the consolidated balance sheets.  All other costs, such as costs of services performed under the contract, general and administrative expenses, and advertising expenses are expensed as incurred.

The liability for extended protection plan claims incurred is included in other current liabilities on the consolidated balance sheets and was not material in any of the periods presented.  Expenses for claims are recognized when incurred and totaled  $46 million and $36 million  for the three months ended May 4, 2018 and May 5, 2017 , respectively.

Disaggregation of Revenues

The following table presents the Company's net sales disaggregated by merchandise division:

The following table presents the Company's net sales disaggregated by geographical area:

Practical Expedients

Sales commissions and selling-related goods or services are considered immaterial and are expensed as incurred because the amortization period of the assets would be one year or less. These costs are reflected within selling, general and administrative expenses.

Note 3 : Fair Value Measurements - Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative guidance for fair value measurements establishes a three-level hierarchy, which encourages an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the hierarchy are defined as follows:

Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

The following table presents the Company's financial assets measured at fair value on a recurring basis as of May 4, 2018 , May 5, 2017 , and February 2, 2018 . The fair values of these instruments approximated amortized costs.

There were no transfers between Levels 1, 2 or 3 during any of the periods presented.

When available, quoted prices were used to determine fair value. When quoted prices in active markets were available, investments were classified within Level 1 of the fair value hierarchy. When quoted prices in active markets were not available, fair values were determined using pricing models, and the inputs to those pricing models were based on observable market inputs. The inputs to the pricing models were typically benchmark yields, reported trades, broker-dealer quotes, issuer spreads and benchmark securities, among others.

Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

During the three months ended May 4, 2018 and May 5, 2017 , the Company had no significant measurements of assets and liabilities at fair value on a nonrecurring basis subsequent to their initial recognition.

Fair Value of Financial Instruments

The Company's financial instruments not measured at fair value on a recurring basis include cash and cash equivalents, accounts receivable, short-term borrowings, accounts payable, accrued liabilities and long-term debt and are reflected in the financial statements at cost. With the exception of long-term debt, cost approximates fair value for these items due to their short-term nature. The fair values of the Company's unsecured notes were estimated using quoted market prices. The fair values of the Company's mortgage notes were estimated using discounted cash flow analyses, based on the future cash outflows associated with these arrangements and discounted using the applicable incremental borrowing rate.

Carrying amounts and the related estimated fair value of the Company's long-term debt, excluding capitalized lease obligations, are as follows:

Note 4 : Restricted Investment Balances - Short-term and long-term investments include restricted balances pledged as collateral primarily for the Company's extended protection plan program. Restricted balances included in short-term investments were $188 million at May 4, 2018 , $70 million at May 5, 2017 , and $86 million at February 2, 2018 .

Restricted balances included in long-term investments were $298 million at May 4, 2018 , $340 million at May 5, 2017 , and $381 million at February 2, 2018 .

Note 5 : Property - Property is shown net of accumulated depreciation of $17.4 billion at May 4, 2018 , $16.9 billion at May 5, 2017 , and $17.2 billion at February 2, 2018 .

Note 6 : Shareholders' Equity - The Company has a share repurchase program that is executed through purchases made from time to time either in the open market, which may be made under pre-set trading plans meeting the requirements of Rule 10b5-1(c) of the Securities Exchange Act of 1934, or through private off-market transactions. Shares purchased under the repurchase program are retired and returned to authorized and unissued status. On January 27, 2017, the Company's Board of Directors authorized a $5.0 billion share repurchase program with no expiration, which was announced on the same day. On January 26, 2018, the Company's Board of Directors authorized an additional $5.0 billion share repurchase program with no expiration, which was announced on the same day. As of May 4, 2018 , the Company had $6.2 billion remaining in its share repurchase program.

During the three months ended May 4, 2018 , the Company repurchased shares of its common stock through the open market totaling 8.7 million shares for a cost of $750 million .

The Company also withholds shares from employees to satisfy either the exercise price of stock options exercised or the statutory withholding tax liability resulting from the vesting of share-based awards.

Shares repurchased for the three months ended May 4, 2018 and May 5, 2017 were as follows:

Note 7 : Earnings Per Share - The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating security as if all of the net earnings for the period had been distributed. The Company's participating securities consist of share-based payment awards that contain a nonforfeitable right to receive dividends and, therefore, are considered to participate in undistributed earnings with common shareholders.

Basic earnings per common share excludes dilution and is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares as of the balance sheet date, as adjusted for the potential dilutive effect of non-participating share-based awards. The following table reconciles earnings per common share for the three months ended May 4, 2018 and May 5, 2017 :

Stock options to purchase 0.6 million and 0.8 million shares of common stock were anti-dilutive for the three months ended May 4, 2018 and May 5, 2017 , respectively.

Note 8 : Income Taxes - The Company's effective income tax rates were 24.3% and 35.5% for the three months ended May 4, 2018 and May 5, 2017 , respectively. The lower effective income tax rate for the three months ended May 4, 2018 was primarily due to the enactment of the Tax Cuts and Jobs Act (Tax Act) during fiscal 2017, which lowered the corporate federal income tax rate from 35% to 21%.

Based on the Company's interpretation of the Tax Act, the Company made reasonable estimates to record provisional adjustments during the fourth quarter of fiscal 2017. However, the final impact may differ due to subsequent legislative action, changes in interpretations and assumptions, as well as the issuance of additional guidance from the Internal Revenue Service and state taxing authorities. We have not made any measurement-period adjustments related to these items during the three months ended May 4, 2018 , because we have not finalized the following items: the earnings and profits of the relevant subsidiaries, deemed repatriation of deferred foreign income, and prior year deferred tax activity. The Company will continue to evaluate the Tax Act and gather additional information within the measurement period allowed, which will be completed no later than the fourth quarter of fiscal 2018.

Results of Review of Interim Financial Information

We have reviewed the accompanying consolidated balance sheets of Lowe's Companies, Inc. and subsidiaries (the "Company") as of May 4, 2018 and May 5, 2017, the related consolidated statements of current and retained earnings, comprehensive income, and cash flows for the fiscal three-month periods ended May 4, 2018 and May 5, 2017, and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of February 2, 2018, and the related consolidated statements of earnings, comprehensive income, shareholders' equity, and cash flows for the fiscal year then ended (not presented herein); and in our report dated April 2, 2018, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of February 2, 2018 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This discussion and analysis summarizes the significant factors affecting our consolidated operating results, liquidity and capital resources during the three months ended May 4, 2018 , and May 5, 2017 . This discussion and analysis should be read in conjunction with the consolidated financial statements and notes to the consolidated financial statements that are included in our Annual Report on Form 10-K for the fiscal year ended February 2, 2018 (the Annual Report), as well as the consolidated financial statements (unaudited) and notes to the consolidated financial statements (unaudited) contained in this report. Unless otherwise specified, all comparisons made are to the corresponding period of 2017 . This discussion and analysis is presented in six sections:

EXECUTIVE OVERVIEW

Net sales and net earnings increased for the first quarter of 2018 by 3.0% to $17.4 billion and 64.1% to $988 million , respectively. Diluted earnings per common share increased 70.0% in the first quarter of 2018 to $1.19 from $0.70 in the first quarter of the prior year. Diluted earnings per common share in the first quarter of 2018 increased 15.5% from adjusted diluted earnings per share of $1.03 in the same period of the prior year (see discussion of non-GAAP financial measures beginning on page 17). During the first quarter, the Company adopted the revenue recognition accounting standard ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , (ASU 2014-09) resulting in the reclassification of certain items within operating income. This accounting standard has been adopted on a modified retrospective basis, therefore, the prior year has not been adjusted. The net effect of this change was an increase to sales of approximately $129 million in the first quarter, driven primarily by the reclassification of profit sharing income associated with the proprietary credit program from SG&A. Continuing to deliver on our commitment to return excess cash to shareholders, during the first quarter of 2018 , we paid $340 million in dividends and repurchased $750 million of common stock through our share repurchase program.

We entered the first quarter of 2018 well positioned to capitalize on Spring demand with enhanced marketing activity, targeted digital marketing content, strong product assortment, and seasonal staffing to help customers complete their home improvement projects. A late Spring selling season generated by unfavorable weather across geographies restricted traffic growth and exerted pressure on comparable sales, negatively impacting outdoor product categories. During the first quarter of 2018 , six of 14 U.S. regions generated comparable sales increases while two regions were flat. Five of 11 product categories generated positive comparable sales while one product category was flat, with particular strength in Appliances, Rough Plumbing & Electrical, Lumber & Building Materials, Tools & Hardware, and Millwork. We continued to see strong demand from the Pro customer for the quarter with comparable sales above the company average.

During the quarter, we continued taking the necessary actions to transform our supply chain, better empower our associates, and re-engineer key processes such as Pick Up In Store and centralized project quoting. We are working to improve traffic conversion by accelerating associate readiness and knowledge through our training programs and better aligning staffing to customer traffic. In addition, we continued to advance our Pick Up In Store experience, with dedicated space and clear signage to ensure that product is staged and ready for pickup within two hours of an order being placed. The new process drives greater efficiency in order fulfillment and improves our ability to meet the expectations of customers allowing them to pick up products quickly.

In 2018, we will continue to focus our resources in what is most relevant to the customer, building the capabilities required to deliver simple and seamless omni-channel experiences for customers and engaging them in the moments that matter most. This will allow us to strengthen our competitiveness and position us to continue to capitalize on home improvement demand.

On May 20, 2018, the Company's Board of Directors appointed Marvin R. Ellison as President and Chief Executive Officer, in each case, effective as of July 2, 2018, at which time he will also join the Board of Directors. On May 20, 2018, the Board of Directors also appointed Richard W. Dreiling as Chairman of the Board of Directors, effective as of July 2, 2018. Mr. Ellison and Mr. Dreiling will succeed Robert A. Niblock, who will be retiring as Chairman, President and Chief Executive Officer of the Company and member of the Board of Directors, in each case, effective as of July 2, 2018.

On June 4, 2018, the Company announced that Marshall A. Croom plans to retire from the Company, effective October 5, 2018. Mr. Croom will continue in his role as Chief Financial Officer until his successor is appointed, and then remain with the Company during a transition period until his retirement date.

OPERATIONS

The following tables set forth the percentage relationship to net sales of each line item of the consolidated statements of current and retained earnings (unaudited), as well as the percentage change in dollar amounts from the prior period. These tables should be read in conjunction with the following discussion and analysis and the consolidated financial statements (unaudited), including the related notes to the consolidated financial statements (unaudited).

Note: The Company adopted ASU 2014-09 and all the related amendments using the modified retrospective method, effective February 3, 2018. Prior period results have not been restated, which affects comparability.

Non-GAAP Financial Measures

Adjusted Diluted Earnings Per Share

Adjusted diluted earnings per share is considered a non-GAAP financial measure. The Company believes this non-GAAP financial measure provides useful insight for analysts and investors in evaluating what management considers the Company's core financial performance. Adjusted diluted earnings per share excludes the impact of certain discrete items, as further described below, not contemplated in the Company's original business outlook for fiscal 2017. Unless otherwise noted, the income tax effect of these adjustments is calculated using the marginal rates for the respective periods.

In the first quarter of 2017, the Company recognized a $464 million loss on extinguishment of debt in connection with a $1.6 billion cash tender offer.

Adjusted diluted earnings per share should not be considered an alternative to, or more meaningful indicator of, the Company's diluted earnings per common share as prepared in accordance with GAAP. The Company's methods of determining this non-GAAP financial measure may differ from the method used by other companies for this or similar non-GAAP financial measures. Accordingly, these non-GAAP measures may not be comparable to the measures used by other companies.

Return on Invested Capital

Return on Invested Capital (ROIC) is calculated using a non-GAAP financial measure. We believe ROIC is a meaningful metric for investors because it represents management's measure of how effectively the Company is using capital to generate profits. Although ROIC is a common financial metric, numerous methods exist for calculating ROIC.  Accordingly, the method used by our management to calculate ROIC may differ from the methods other companies use to calculate their ROIC.  We encourage you to understand the methods used by another company to calculate its ROIC before comparing its ROIC to ours.

We define ROIC as trailing four quarters' net operating profit after tax (NOPAT) divided by the average of ending debt and equity for the last five quarters. NOPAT is a non-GAAP financial measure, and net earnings is considered to be the most comparable GAAP financial measure to NOPAT. The calculation of ROIC, together with a reconciliation of NOPAT to net earnings, the most comparable GAAP financial measure, is as follows:

Results of Operations

Net Sales – Net sales for the first quarter of 2018 increased 3.0% to $17.4 billion . The adoption of the revenue recognition accounting standard ASU 2014-09, contributed 0.8% to sales growth, primarily due to a reclassification of profit sharing income associated with the proprietary credit program from SG&A to sales. Comparable sales increased 0.6% over the same period, driven by a 4.3% increase in comparable average ticket, offset by a 3.7% decrease in comparable customer transactions. New stores and the addition of Maintenance Supply Headquarters also contributed to sales growth during the quarter.

During the first quarter of 2018 , we experienced comparable sales increases in five of 11 product categories, as well as flat comparable sales in Fashion Fixtures. Comparable sales increases were above the company average in Appliances, Rough

Plumbing & Electrical, Lumber & Building Materials, Tools & Hardware, and Millwork. Strong brand and service advantages in Appliances, as well as our continued investment in customer experience both in-store and online, drove double-digit comparable sales during the quarter. We achieved strong comparable sales in Rough Plumbing & Electrical driven by continued improvements in brand relevance and demand from the Pro customer. In addition, Tools & Hardware, Lumber & Building Materials, and Millwork also continued to benefit from strong demand from the Pro customer.

Gross Margin – For the first quarter of 2018 , gross margin increased 23 basis points as a percentage of sales. Gross margin was positively impacted by 58 basis points due to the adoption of the revenue recognition accounting standard ASU 2014-09, which primarily resulted in a reclassification of profit sharing income associated with the proprietary credit program from SG&A to sales. In addition, gross margin was positively impacted by approximately 10 basis points due to value improvement and pricing optimization efforts. These were partially offset by approximately 15 basis points due to competitive actions taken in the prior year and approximately 5 basis points due to mix of products sold. Transportation costs, shrink, and inflation negatively impacted gross margin by 15 basis points during the quarter.

SG&A – For the first quarter of 2018 , SG&A expense deleveraged 113 basis points as a percentage of sales compared to the first quarter of 2017 . This was driven by 66 basis points of deleverage due to the adoption of the revenue recognition accounting standard ASU 2014-09, which primarily resulted in a reclassification of profit sharing income associated with the proprietary credit program from SG&A to sales, 32 basis points of deleverage in operating salaries, and 18 basis points of deleverage in customer delivery to meet increased demand in Appliances.

Depreciation and Amortization – Depreciation and amortization leveraged 9 basis points for the first quarter of 2018 compared to the prior year primarily due to assets becoming fully depreciated. Property, less accumulated depreciation, decreased to $19.5 billion at May 4, 2018 , compared to $19.7 billion at May 5, 2017 . As of May 4, 2018 and May 5, 2017 , we owned 79% of our stores, which included stores on leased land.

Interest – Net – Interest expense for the first quarter of 2018 decreased primarily as a result of the cash tender offer to purchase and retire $1.6 billion aggregate principal amount of our outstanding notes in the first quarter of 2017 and the payoff of scheduled debts at maturity. These were partially offset by the issuance of unsecured notes in May 2017.

Loss on Extinguishment of Debt – During the first quarter of 2017, we repurchased and retired $1.6 billion aggregate principal amount of our outstanding debt resulting in a loss on extinguishment of debt of $464 million.

Income Tax Provision – Our effective income tax rates were 24.3% and 35.5% for the three months ended May 4, 2018 and May 5, 2017 , respectively. The decrease in the effective income tax rate is primarily due to the enactment of the Tax Act, effective January 1, 2018, which lowered the federal tax rate from 35% to 21%.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

Sources of Liquidity

Cash flows from operations, supplemented with our short-term and long-term borrowings, have been sufficient to fund our operations while allowing us to make strategic investments that will grow our business, and to return excess cash to shareholders in the form of dividends and share repurchases. We believe that our sources of liquidity will continue to be adequate to fund our operations and investments to grow our business, repay our debt as it becomes due, pay dividends, and fund our share repurchases over the next 12 months.

Cash Flows Provided by Operating Activities

Cash flows from operating activities continued to provide the primary source of our liquidity.  The increase in net cash provided by operating activities for the three months ended May 4, 2018 , versus the three months ended May 5, 2017 , was driven primarily by changes in working capital, partially offset by a decrease in net earnings adjusted for non‐cash expenses.

Cash Flows Used in Investing Activities

Net cash used in investing activities primarily consist of transactions related to capital expenditures.

Capital expenditures

Our capital expenditures generally consist of investments in our strategic initiatives to enhance our ability to serve customers, existing stores, and expansion plans. The following table provides our capital expenditures for the three months ended May 4, 2018 , and May 5, 2017 :

Our 2018 capital expenditures forecast is approximately $1.7 billion. The increase in our forecast, relative to historical capital expenditures, is primarily attributable to incremental cash flow benefit related to the enactment of the Tax Cuts and Jobs Act of 2017.

Cash Flows Used in Financing Activities

Net cash used in financing activities primarily consist of transactions related to our short-term borrowings, long-term debt, share repurchases, and cash dividend payments.

Short-term Borrowing Facilities

We have an unsecured revolving credit agreement with a syndicate of banks (the 2016 Credit Facility) which provides for borrowings up to $1.75 billion and supports our commercial paper program. The amount available to be drawn under the 2016 Credit Facility is reduced by the amount of borrowings under our commercial paper program. All of our short-term borrowings in the three months ended May 4, 2018 , and May 5, 2017 , were under the commercial paper program. The following table includes additional information related to our short-term borrowings for the three months ended May 4, 2018 , and May 5, 2017 :

The 2016 Credit Facility expires in November 2021 and contains customary representations, warranties, and covenants. We were in compliance with those covenants at May 4, 2018 . Subject to obtaining commitments from the lenders and satisfying other conditions specified in the 2016 Credit Facility, the Company may increase the aggregate availability by an additional $500 million.

Long-term Debt

The following table includes additional information related to the Company's long-term debt for the three months ended May 4, 2018 , and May 5, 2017 :

During the three months ended May 5, 2017 , we paid approximately $2.0 billion to purchase $1.6 billion of our higher coupon notes prior to maturity in connection with a cash tender offer. We issued $3.0 billion of unsecured notes to fund the tender offer, finance current year maturities, and for other general corporate purposes, which included share repurchases, capital expenditures, strategic investments, and working capital needs.

Share Repurchases

We have an ongoing share repurchase program, authorized by the Company's Board of Directors, that is executed through purchases made from time to time either in the open market or through private off-market transactions. We also withhold shares from employees to satisfy tax withholding liabilities. Shares repurchased are retired and returned to authorized and unissued status. The following table provides, on a settlement date basis, the total number of shares repurchased, average price paid per share, and the total amount paid for share repurchases for the three months ended May 4, 2018 , and May 5, 2017 :

As of May 4, 2018 , we had $6.2 billion remaining available under our share repurchase program with no expiration date. We expect to repurchase shares totaling $2.5 billion in 2018 (including the amount repurchased in the first quarter of fiscal year 2018). See Note 6 to the consolidated financial statements included herein for additional information regarding share repurchases.

Dividends

Our dividend payment dates are established such that dividends are paid in the quarter immediately following the quarter in which they are declared. The following table provides additional information related to our dividend payments for three months ended May 4, 2018 , and May 5, 2017 :

Capital Resources

We expect to continue to have access to the capital markets on both short-term and long-term bases when needed for liquidity purposes by issuing commercial paper or new long-term debt. The availability and the borrowing costs of these funds could be adversely affected, however, by a downgrade of our debt ratings or a deterioration of certain financial ratios.  The table below reflects our debt ratings by Standard & Poor's (S&P) and Moody's as of June 5, 2018 , which we are disclosing to enhance

understanding of our sources of liquidity and the effect of our ratings on our cost of funds.  Our debt ratings have enabled, and should continue to enable, us to refinance our debt as it becomes due at favorable rates in capital markets. Although we currently do not expect a downgrade in our debt ratings, our commercial paper and senior debt ratings may be subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be evaluated independently of any other rating.

There are no provisions in any agreements that would require early cash settlement of existing debt or leases as a result of a downgrade in our debt rating or a decrease in our stock price.  In addition, we do not believe it will be necessary to repatriate significant cash and cash equivalents and short-term investments held in foreign affiliates to fund domestic operations.

OFF-BALANCE SHEET ARRANGEMENTS

Other than in connection with executing operating leases, we do not have any off-balance sheet financing that has, or is reasonably likely to have, a material, current or future effect on our financial condition, cash flows, results of operations, liquidity, capital expenditures or capital resources.

CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS

As of May 4, 2018 , there were no material changes to our contractual obligations and commercial commitments outside the ordinary course of business since the end of 2017 . Refer to the Annual Report on Form 10-K for additional information regarding our contractual obligations and commercial commitments.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our significant accounting policies are described in Note 1 to the consolidated financial statements presented in the Annual Report. Our critical accounting policies and estimates are described in "Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Annual Report. Our significant and critical accounting policies have not changed significantly since the filing of the Annual Report.

FORWARD-LOOKING STATEMENTS

This Form 10-Q includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Statements including words such as "believe," "expect," "anticipate," "plan," "desire," "project," "estimate," "intend," "will," "should," "could," "would," "may," "strategy," "potential," "opportunity," and similar expressions are forward-looking statements. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Forward-looking statements include, but are not limited to, statements about future financial and operating results, Lowe's plans, objectives, business outlook, priorities, expectations and intentions, expectations for sales growth, comparable sales, earnings and performance, shareholder value, capital expenditures, cash flows, the housing market, the home improvement industry, demand for services, share repurchases, Lowe's strategic initiatives, including those relating to acquisitions by Lowe's and the expected impact of such transactions on our strategic and operational plans and financial results, and any statement of an assumption underlying any of the foregoing and other statements that are not historical facts. Although we believe that the expectations, opinions, projections and comments reflected in these forward-looking statements are reasonable, such statements involve risks and uncertainties and we can give no assurance that such statements will prove to be correct. Actual results may differ materially from those expressed or implied in such statements.

A wide variety of potential risks, uncertainties and other factors could materially affect our ability to achieve the results either expressed or implied by these forward-looking statements including, but not limited to, changes in general economic conditions, such as the rate of unemployment, interest rate and currency fluctuations, changes to tax laws applicable to corporate multinationals, such as the recently enacted U.S. Tax Cuts and Jobs Act of 2017, fuel and other energy costs, slower growth in personal income, changes in consumer spending, changes in the rate of housing turnover, the availability of consumer credit and of mortgage financing, inflation or deflation of commodity prices, disruptions caused by our management changes, and other factors that can negatively affect our customers, as well as our ability to: (i) respond to adverse trends in the housing industry, a reduced rate of growth in household formation, and slower rates of growth in housing renovation and repair activity,

as well as uneven recovery in commercial building activity; (ii) secure, develop, and otherwise implement new technologies and processes necessary to realize the benefits of our strategic initiatives focused on omni-channel sales and marketing presence and enhance our efficiency; (iii) attract, train, and retain highly-qualified associates; (iv) manage our business effectively as we adapt our operating model to meet the changing expectations of our customers; (v) maintain, improve, upgrade and protect our critical information systems from data security breaches, ransomware and other cyber threats; (vi) respond to fluctuations in the prices and availability of services, supplies, and products; (vii) respond to the growth and impact of competition; (viii) address changes in existing or new laws or regulations that affect consumer credit, employment/labor, trade, product safety, transportation/logistics, energy costs, health care, tax or environmental issues; (ix) positively and effectively manage our public image and reputation and respond appropriately to unanticipated failures to maintain a high level of product and service quality that could result in a negative impact on customer confidence and adversely affect sales; and (x) effectively manage our relationships with selected suppliers of brand name products and key vendors and service providers, including third-party installers. In addition, we could experience impairment losses if either the actual results of our operating stores are not consistent with the assumptions and judgments we have made in estimating future cash flows and determining asset fair values, or we are required to reduce the carrying amount of our investment in certain unconsolidated entities. With respect to acquisitions, potential risks include the effect of such transactions on Lowe's and the target company's strategic relationships, operating results and businesses generally; our ability to integrate personnel, labor models, financial, IT and other systems successfully; disruption of our ongoing business and distraction of management; hiring additional management and other critical personnel; increasing the scope, geographic diversity, and complexity of our operations; significant integration costs or unknown liabilities; and failure to realize the expected benefits of the transaction. For more information about these and other risks and uncertainties that we are exposed to, you should read "Item 1A - Risk Factors" and "Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates" included in our most recent Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the SEC) and the description of material changes thereto, if any, included in our Quarterly Reports on Form 10-Q or subsequent filings with the SEC.

The forward-looking statements contained in this Form 10-Q are expressly qualified in their entirety by the foregoing cautionary statements.

Item 3. - Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to certain market risks, including changes in foreign currency exchange rates related to our international operations, interest rates, and commodity prices. The Company's market risks have not changed materially from that disclosed in the Annual Report for the fiscal year ended February 2, 2018.

Item 4. - Controls and Procedures

The Company's management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness of the Company's "disclosure controls and procedures," (as such term is defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act)). Based upon their evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that, as of May 4, 2018 , the Company's disclosure controls and procedures were effective for the purpose of ensuring that the information required to be disclosed in the reports that the Company files or submits under the Exchange Act with the SEC (1) is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and (2) is accumulated and communicated to the Company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

In addition, no change in the Company's internal control over financial reporting occurred during the quarter ended May 4, 2018 , that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

Part II – OTHER INFORMATION

Item 1. - Legal Proceedings

The Company is from time to time a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. With respect to such lawsuits, claims and proceedings, the Company records reserves when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe that any of these proceedings, individually or in the aggregate, would be expected to have a material adverse effect on its results of operations, financial position or cash flows. The Company maintains liability insurance for certain risks that are subject to certain self-insurance limits.

Item 1A. - Risk Factors

There have been no material changes in the Company's risk factors from those disclosed in "Item 1A - Risk Factors" in the Annual Report, except with respect to the risk factor regarding the retirement of our Chief Executive Officer and the appointment of a new Chief Executive Officer, which has been amended and restated as follows:

If we do not successfully manage the transitions associated with the retirement of our Chairman and Chief Executive Officer and Chief Financial Officer and the appointment of a new Chairman and a new Chief Executive Officer and Chief Financial Officer, it could be viewed negatively by our customers and shareholders and could have an adverse impact on our business.

On March 26, 2018, we announced that Robert A. Niblock planned to retire as Chairman of the Board of Directors, President and Chief Executive Officer after a 25-year career with the Company. On May 20, 2018, the Board of Directors appointed Marvin R. Ellison as President and Chief Executive Officer, in each case, effective as of July 2, 2018, at which time he will also join the Board of Directors. On May 20, 2018, the Board of Directors also appointed Richard R. Dreiling as Chairman of the Board of Directors, effective as of July 2, 2018. Mr. Ellison and Mr. Dreiling will succeed Mr. Niblock, who will be retiring as Chairman, President and Chief Executive Officer of the Company and member of the Board of Directors, in each case, effective as of July 2, 2018. On June 4, 2018, we announced that Marshall A. Croom plans to retire from the Company, effective October 5, 2018. Mr. Croom will continue in his role as Chief Financial Officer until his successor is appointed, and then remain with the Company during a transition period until his retirement date. Such leadership transitions can be inherently difficult to manage, and an inadequate transition may cause disruption to our business, including to our relationships with our customers, suppliers, vendors and employees. It may also make it more difficult to hire and retain key employees.
