BASIS OF PRESENTATION

BASIS OF PRESENTATION	9 Months Ended
	Sep. 30, 2024
Basis of Presentation
Basis of Presentation	Note 1– Basis of Presentation ​ The accompanying unaudited condensed consolidated financial statements of PC Connection, Inc. and its subsidiaries, or the Company, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting and in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. Such principles were applied on a basis consistent with the accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. ​ In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results of operations for the interim periods reported and of the Company’s financial condition as of the date of the interim balance sheet. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements. The operating results for the three and nine months ended September 30, 2024 may not be indicative of the results expected for any succeeding quarter or the entire year ending December 31, 2024. ​ Use of Estimates in the Preparation of Financial Statements ​ The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts and disclosures of assets and liabilities and the reported amounts and disclosures of revenue and expenses during the period. Management bases its estimates and judgments on the information available at the time and various other assumptions believed to be reasonable under the circumstances. By nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ from those estimates and assumptions. ​ Cash and Cash Equivalents and Investments ​ The Company considers all highly liquid short-term investments with original maturities of 90 days or less to be cash equivalents. The carrying value of the Company’s cash equivalents approximates fair value. 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. ​ At the time of purchase, the Company determines the appropriate classification of investments based upon its intent with regard to such investments. All of the Company’s investments are classified as available-for-sale. The Company classifies investments as short-term when their remaining contractual maturities are one year or less from the balance sheet date, and as long-term when the investment has a remaining contractual maturity of more than one year from the balance sheet date. The Company records investments at fair value with unrealized gains and losses recorded as a component of accumulated other comprehensive income on the condensed consolidated balance sheets. ​ Included in interest income, net on the condensed consolidated statements of income is interest income on cash equivalents and short-term investments of $4,840 and $14,060 for the three and nine months ended September 30, 2024, respectively, and $2,684 and $5,866 for the three and nine months ended September 30, 2023, respectively. ​ Treasury Stock, at Cost ​ The total repurchases for the nine months ended September 30, 2024 and 2023 were recorded as treasury stock of $7,723 and $5,446, respectively. Such costs reflect the applicable one percent excise tax imposed by the Inflation Reduction Act of 2022 on the net value of certain stock repurchases made after December 31, 2022. ​ Restructuring and Other Charges ​ The restructuring and other charges recorded for the three and nine months ended September 30, 2024 and 2023 were primarily related to an involuntary reduction in the Company’s headquarter workforce and included cash severance and other related termination benefits. No amounts related to these costs are included in accrued expenses and other liabilities as all such amounts have been paid as of September 30, 2024. ​ Restructuring and other charges are presented separately from selling, general and administrative expenses. Costs incurred were as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ ​ 2024 ​ 2023 ​ 2024 ​ 2023 Employee separations ​ $ — ​ $ 17 ​ $ 415 ​ $ 2,416 Other charges ​ — ​ 27 ​ — ​ 271 Total restructuring and other charges ​ $ — ​ $ 44 ​ $ 415 ​ $ 2,687 ​ Recently Issued Financial Accounting Standards ​ In November 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ​ In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ​

All short-term investments had stated maturity dates of less than one year. The Company has recorded the securities at fair value on its condensed consolidated balance sheets and unrealized gains and losses are reported as a component of accumulated other comprehensive income. The amount of realized gains and losses reclassified into earnings and the related adjustments to deferred taxes are based on the specific identification of the securities sold or securities that reached maturity date. ​ Fair Value ​ The Company measures certain financial assets at fair value. Fair value is determined based upon the exit price that would be received to sell an asset in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques are classified based on a three-level hierarchy, as follows: ​ ● Level 1 inputs: Quoted prices for identical assets or liabilities in active markets; ​ ● Level 2 inputs: Observable inputs other than those described as Level 1; and ​ ● Level 3 inputs: Unobservable inputs that are supported by little or no market activities and are based on significant assumptions and estimates. ​ As of September 30, 2024 and December 31, 2023, the fair value of the Company’s investments were all measured using level 1 inputs.

Earnings Per Share [Abstract]
Earnings Per Share	Note 4–Earnings Per Share ​ Basic earnings per common share is computed using the weighted average number of shares outstanding. Diluted earnings per share is computed using the weighted average number of shares outstanding adjusted for the incremental shares attributable to non-vested stock units and stock options outstanding, if dilutive. ​ The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2024 and 2023 (in thousands, except per share data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ ​ 2024 2023 2024 2023 Numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income ​ $ 27,059 ​ $ 25,598 ​ $ 66,374 ​ $ 59,493 ​ Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Denominator for basic earnings per share ​ 26,292 ​ 26,262 ​ 26,334 ​ 26,281 ​ Dilutive effect of employee stock awards ​ 209 ​ 172 ​ 184 ​ 125 ​ Denominator for diluted earnings per share ​ 26,501 ​ 26,434 ​ 26,518 ​ 26,406 ​ Earnings per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic ​ $ 1.03 ​ $ 0.97 ​ $ 2.52 ​ $ 2.26 ​ Diluted ​ $ 1.02 ​ $ 0.97 ​ $ 2.50 ​ $ 2.25 ​ ​ For the three and nine months ended September 30, 2024 and 2023, the Company had no outstanding non-vested stock units that were excluded from the computation of diluted earnings per share because including them would have had an anti-dilutive effect.

Segment Information
Segment and Related Disclosures	Note 6–Segment Information ​ The internal reporting structure used by the Company’s chief operating decision maker, or CODM, to assess performance and allocate resources determines the basis for the Company’s operating segments. The Company’s CODM is its Chief Executive Officer, and he evaluates operations and allocates resources based on a measure of operating income. ​ The Company’s operations are organized under three segments—the Enterprise Solutions segment, which serves primarily medium-to-large corporations; the Business Solutions segment, which serves primarily small- to medium-sized businesses; and the Public Sector Solutions segment, which serves primarily federal, state, and local government and educational institutions. In addition, the Headquarters/Other group provides services in areas such as finance, human resources, information technology, or IT, marketing, and product management. Most of the operating costs associated with the Headquarters/Other group functions are charged to the operating segments based on their estimated usage of the underlying functions. The Company reports these charges to the operating segments as “Allocations”. Certain headquarters costs relating to executive oversight and other fiduciary functions that are not allocated to the operating segments are included under the heading of Headquarters/Other in the tables below. ​ Net sales presented below exclude inter-segment product revenues.

This facility can be increased, at the Company’s option, to $80,000 for permitted acquisitions or other uses authorized by the lender on substantially the same terms. Amounts outstanding under this facility bear interest at the daily Bloomberg Short-Term Bank Yield Index, or BSBY Rate, plus a spread based on the Company’s funded debt ratio, or in the absence of BSBY Rate, the prime rate ​ Cash receipts are automatically applied against any outstanding borrowings. During the nine months ended September 30, 2024 and 2023, the Company borrowed incremental amounts that were each repaid in full. These borrowings for the nine months ended September 30, 2024 and 2023 totaled $25,204 and $70,877, respectively; however, at no time were the outstanding borrowings greater than the $50,000 limit under the credit facility. The Company had no outstanding borrowings under the credit facility as of September 30, 2024 or 2023, and accordingly, the entire $50,000 credit facility was available for borrowings on such date.

Summary of Significant Accounting Policies
Basis of Presentation	​ The accompanying unaudited condensed consolidated financial statements of PC Connection, Inc. and its subsidiaries, or the Company, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting and in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. Such principles were applied on a basis consistent with the accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. ​ In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results of operations for the interim periods reported and of the Company’s financial condition as of the date of the interim balance sheet. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements. The operating results for the three and nine months ended September 30, 2024 may not be indicative of the results expected for any succeeding quarter or the entire year ending December 31, 2024. ​
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements ​ The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts and disclosures of assets and liabilities and the reported amounts and disclosures of revenue and expenses during the period. Management bases its estimates and judgments on the information available at the time and various other assumptions believed to be reasonable under the circumstances. By nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ from those estimates and assumptions.
Cash and Cash Equivalents and Investments	Cash and Cash Equivalents and Investments ​ The Company considers all highly liquid short-term investments with original maturities of 90 days or less to be cash equivalents. The carrying value of the Company’s cash equivalents approximates fair value. 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. ​ At the time of purchase, the Company determines the appropriate classification of investments based upon its intent with regard to such investments. All of the Company’s investments are classified as available-for-sale. The Company classifies investments as short-term when their remaining contractual maturities are one year or less from the balance sheet date, and as long-term when the investment has a remaining contractual maturity of more than one year from the balance sheet date. The Company records investments at fair value with unrealized gains and losses recorded as a component of accumulated other comprehensive income on the condensed consolidated balance sheets. ​ Included in interest income, net on the condensed consolidated statements of income is interest income on cash equivalents and short-term investments of $4,840 and $14,060 for the three and nine months ended September 30, 2024, respectively, and $2,684 and $5,866 for the three and nine months ended September 30, 2023, respectively.
Treasury Stock, at Cost	Treasury Stock, at Cost ​ The total repurchases for the nine months ended September 30, 2024 and 2023 were recorded as treasury stock of $7,723 and $5,446, respectively. Such costs reflect the applicable one percent excise tax imposed by the Inflation Reduction Act of 2022 on the net value of certain stock repurchases made after December 31, 2022.
Restructuring and other charges	Restructuring and Other Charges ​ The restructuring and other charges recorded for the three and nine months ended September 30, 2024 and 2023 were primarily related to an involuntary reduction in the Company’s headquarter workforce and included cash severance and other related termination benefits. No amounts related to these costs are included in accrued expenses and other liabilities as all such amounts have been paid as of September 30, 2024. ​ Restructuring and other charges are presented separately from selling, general and administrative expenses. Costs incurred were as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ ​ 2024 ​ 2023 ​ 2024 ​ 2023 Employee separations ​ $ — ​ $ 17 ​ $ 415 ​ $ 2,416 Other charges ​ — ​ 27 ​ — ​ 271 Total restructuring and other charges ​ $ — ​ $ 44 ​ $ 415 ​ $ 2,687 ​
