The Company offers a full range of products, marketing programs and technology solutions to approximately 40,000 customer locations in the United States (“U.S.”) and Canada. The Company’s customers include traditional convenience stores, drug stores, mass merchants, grocery stores, liquor stores and other specialty and small format stores that carry convenience products. The Company’s product offering includes cigarettes, other tobacco products (“OTP”), alternative nicotine products, candy, snacks, food, including fresh products, groceries, dairy, bread, beverages, general merchandise and health and beauty care products. The Company operates a network of thirty-two distribution centers in the U.S. and Canada (excluding two distribution facilities it operates as a third-party logistics provider). Twenty-seven distribution centers are located in the U.S. and five are located in Canada. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of March 31, 2021, the unaudited condensed consolidated statements of operations and comprehensive income, the unaudited condensed consolidated statements of stockholders’ equity, and the unaudited condensed consolidated statements of cash flows, each for the three months ended March 31, 2021 and 2020, have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. Accordingly, certain footnotes and other financial information that are normally required by generally accepted accounting principles in the U.S. (“GAAP”) have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2020 has been derived from the Company’s audited financial statements, which are included in its 2020 Annual Report on Form 10-K, filed with the SEC on March 1, 2021. The consolidated financial statements include Core-Mark and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K, for the year ended December 31, 2020. The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of the Company’s consolidated results of operations, financial position, comprehensive income, changes in stockholders’ equity and cash flows.

Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Adoption of Accounting Pronouncements On August 28, 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans -General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). The Company adopted this pronouncement on a retrospective basis effective January 1, 2021. The new guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant for defined benefit pension and other post-retirement benefit plans. The adoption of ASU 2018-14 did not have a material impact on the Company’s consolidated financial statements. On December 18, 2019 the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The new guidance enhances and simplifies various aspects of the income tax accounting guidance, including requirements pertaining to hybrid tax regimes, ownership changes in investments, and interim-period accounting for enacted changes in tax law. The Company adopted this pronouncement effective January 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated financial statements. Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high-quality financial institutions and limits the amount of credit exposure in any one financial instrument. A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with an allowance recognized for expected credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary. Murphy U.S.A., the Company’s largest customer, accounted for approximately 14% of the Company’s net sales for each of the three months ended March 31, 2021 and March 31, 2020. No other customer individually accounted for more than 10% of sales for these periods. No sin gle customer individually accounted for 10% or more o f the Company’s accounts receivable as of March 31, 2021 or December 31, 2020.

Inventory Disclosure [Abstract]
Inventories, Net	Inventories, Net Inventories consist of the following (in millions): March 31, December 31, Inventories at FIFO, net of reserves $ 1,002.4 $ 993.9 Less: LIFO reserve (245.9) (235.4) Total inventories, net of reserves $ 756.5 $ 758.5 Cost of goods sold reflects the application of the last-in, first-out (“LIFO”) method of valuing inventories in the U.S. based upon estimated annual producer price indexes. Inventories in Canada are valued on a first-in, first-out (“FIFO”) basis, as LIFO is not a permitted inventory valuation method in Canada. During periods of rising prices, the LIFO method of costing inventories generally results in higher current costs being charged against income while lower costs are retained in inventories. Conversely, during periods of decreasing prices, the LIFO method of costing inventories generally results in lower current costs being charged against income and higher stated inventories. If the FIFO method had been used for valuing inventories in the U.S., inventories would have been approximately $245.9 million and $235.4 million higher as of March 31, 2021 and December 31, 2020, respectively. The Company recorded LIFO expense of $10.5 million and $7.8 million for the three months ended March 31, 2021 and 2020, respectively. During the first quarter of 2021, the Company concluded that it qualifies for and intends to file a change to the tax method of determining the LIFO reserve which increased deferred tax liabilities and decreased taxes payable by approximately $16 million.

Debt Disclosure [Abstract]
Long-term Debt	Long-Term Debt Long-term debt consists of the following (in millions): March 31, December 31, Amounts borrowed (Credit Facility) $ 259.0 $ 258.0 Obligations under finance leases 93.9 86.5 Total long-term debt $ 352.9 $ 344.5 The Company has a revolving credit facility (the “Credit Facility”) with a capacity of $750.0 million and expansion feature of $200.0 million as of March 31, 2021, limited by a borrowing base consisting of eligible accounts receivable and inventories. On February 26, 2021, the Company entered into an eleventh amendment to its Credit Facility (the “Eleventh Amendment”), which primarily extends the maturity date from March 28, 2022 to February 26, 2026. With the Eleventh Amendment, the size and expansion feature of the Credit Facility remain unchanged and certain threshold amounts for reporting and notices as well as the size of certain baskets were increased. The Eleventh Amendment also added certain additional covenant baskets and incorporated customary language regarding London Interbank Offered Rate (“LIBOR”) replacement, defaulting lenders, electronic execution, bail-in acknowledgement and letters of credit. All obligations under the Credit Facility are secured by first-priority liens on substantially all of the Company’s present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect LIBOR or Canadian Dollar Offered Rate (“CDOR”) based loans prepaid prior to the end of an interest period). The Company incurred fees of approximately $2.8 million in connection with the Eleventh Amendment. Amounts related to the Credit Facility are as follows (in millions, except interest rate data): March 31, December 31, Amounts borrowed, net $ 259.0 $ 258.0 Outstanding letters of credit 43.6 19.5 Amounts available to borrow (1) 406.9 402.4 Unamortized debt issuance costs 3.4 0.9 ___________________________________________ (1) Subject to borrowing base limitations, and excluding expansion feature of $200.0 million.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation The Company is subject to certain legal proceedings, claims, investigations and administrative proceedings in the ordinary course of its business. The Company records a provision for a liability when it is probable that the liability has been incurred and the amount of the liability can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. In the opinion of management, the outcome of pending litigation is not expected to have a material effect on the Company’s results of operations, financial condition or liquidity. On October 2, 2019, the United States Judicial Panel on Multidistrict Litigation transferred and consolidated all then-pending personal injury cases against Juul Labs, Inc. (“JLI”) involving the distribution and sale of JUUL products to the Northern District of California (the “JUUL MDL”). Subsequently, on March 11, 2020, the plaintiffs in the JUUL MDL filed a Personal Injury Consolidated Master Complaint against JLI, Philip Morris and various Altria Group entities, JLI co-founders, early JLI investors and board members, certain e-liquid manufacturers, and numerous distributors and retailers of JUUL products, including Core-Mark. Consequently, Core-Mark has been added as a defendant in a number of these personal injury suits. The JLI MDL litigation is currently in an early stage, and the personal injury plaintiffs have not made a monetary demand to the defendants. JLI is indemnifying Core-Mark in connection with the JUUL MDL and similar litigation. On September 25, 2020, Core-Mark filed a petition with the Ontario Superior Court of Justice to appeal a decision with respect to the results of a tax audit for the period of December 2014 through January 2018 pertaining to taxes on sales of other tobacco products to First Nations Consumers. The Ontario Ministry of Finance (the “Ministry”) questions whether the amount of cigars Core-Mark sold to First Nations consumers was a reasonable amount and as a result whether taxes should have been assessed. The position of the Ontario Ministry is based on an undefined standard of what constitutes a reasonable quantum of sales. While the Company remains confident in the validity of its appeal, Core-Mark has decided, based on a recent ruling by the Ontario Divisional Court in a similar matter and that this matter could potentially be resolved between the parties, to record a reserve of approximately 50%, or $3.8 million, against the total tax audit claim. In contrast to rulings by the Ontario Divisional Court, Core-Mark will have the automatic right to appeal to the Ontario Court of Appeal in the event of an unfavorable ruling by the Ontario Superior Court of Justice. Additionally, the Ministry claims Core-Mark sold tobacco to First Nations consumers without a valid permit. The Company is confident that it will be able to demonstrate that valid permits did exist.

As of March 31, 2021, the total number of shares available for issuance under the 2019 LTIP was 2,792,616. The 2019 LTIP allows the Company to grant, among other things, time-vesting and performance-based restricted stock unit awards. Awards may be made under the 2019 LTIP through May 21, 2029. Grant Activities During the three months ended March 31, 2021 and 2020, the Company granted 225,724 and 271,107, respectively, of time-vesting restricted stock units to certain of its employees and non-employee directors at a weighted-average grant date fair value of $30.68 and $25.32, respectively. During the three months ended March 31, 2021, the Company granted 149,524 performance-based restricted stock units to certain of its employees at a weighted-average grant date fair value of $30.67. The 149,524 performance-based restricted stock units represent the maximum number that can be earned. The number of performance-based restricted stock units that employees ultimately earn will be based on the Company’s achievement of certain specified performance targets for the full year of 2021. During the three months ended March 31, 2020, the Company granted 140,536 performance-based restricted stock units to certain of its employees at a weighted-average grant date fair value of $25.32, of which 126,482 were ultimately earned, based upon 2020 performance criteria achieved. Stock-Based Compensation Cost Total stock-based compensation cost included in selling, general and administrative expenses was $2.4 million and $2.0 million for the three months ended March 31, 2021 and 2020, respectively. Total unrecognized stock-based compensation cost related to unvested share-based compensation arrangements was $17.5 million at March 31, 2021, which is expected to be recognized over a weighted-average period of 2.0 years. Total unrecognized stock-based compensation cost is adjusted for any unearned or estimated not to be earned performance-based restricted stock units or forfeited shares.

Segment Reporting [Abstract]
Segment and Geographic Information	Segment and Geographic Information The Company identifies its operating segments based primarily on the way the Chief Operating Decision Maker (“CODM”) evaluates performance and makes decisions. The President and Chief Executive Officer of the Company has been identified as the CODM. From the perspective of the CODM, the Company is engaged primarily in the business of distributing packaged consumer products to convenience retail stores in the U.S. and Canada (collectively “North America”), each of which consists of customers that have similar characteristics.

Basis of Presentation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of March 31, 2021, the unaudited condensed consolidated statements of operations and comprehensive income, the unaudited condensed consolidated statements of stockholders’ equity, and the unaudited condensed consolidated statements of cash flows, each for the three months ended March 31, 2021 and 2020, have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. Accordingly, certain footnotes and other financial information that are normally required by generally accepted accounting principles in the U.S. (“GAAP”) have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2020 has been derived from the Company’s audited financial statements, which are included in its 2020 Annual Report on Form 10-K, filed with the SEC on March 1, 2021. The consolidated financial statements include Core-Mark and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K, for the year ended December 31, 2020. The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of the Company’s consolidated results of operations, financial position, comprehensive income, changes in stockholders’ equity and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods.

Adoption of Accounting Pronouncements	Adoption of Accounting Pronouncements On August 28, 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans -General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). The Company adopted this pronouncement on a retrospective basis effective January 1, 2021. The new guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant for defined benefit pension and other post-retirement benefit plans. The adoption of ASU 2018-14 did not have a material impact on the Company’s consolidated financial statements. On December 18, 2019 the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The new guidance enhances and simplifies various aspects of the income tax accounting guidance, including requirements pertaining to hybrid tax regimes, ownership changes in investments, and interim-period accounting for enacted changes in tax law. The Company adopted this pronouncement effective January 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated financial statements.
Concentration of Credit Risks	Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high-quality financial institutions and limits the amount of credit exposure in any one financial instrument. A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with an allowance recognized for expected credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary.
