1. ORGANIZATION
WESCO International, Inc. ("Wesco International") and its subsidiaries (collectively, “Wesco” or the "Company"), headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.
The Company has operating segments comprising three strategic business units consisting of Electrical & Electronic Solutions ("EES"), Communications & Security Solutions ("CSS") and Utility & Broadband Solutions ("UBS").
2. ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited Condensed Consolidated Financial Statements of Wesco have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial information should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in WESCO International, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 25, 2022. The Condensed Consolidated Balance Sheet at December 31, 2021 was derived from the audited Consolidated Financial Statements as of that date, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America.
The unaudited Condensed Consolidated Balance Sheet as of September 30, 2022, the unaudited Condensed Consolidated Statements of Income and Comprehensive Income and the unaudited Condensed Consolidated Statements of Stockholders' Equity for the three and nine months ended September 30, 2022, and 2021, and the unaudited Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2022, and 2021, respectively, in the opinion of management, have been prepared on the same basis as the audited Consolidated Financial Statements and include all adjustments necessary for the fair statement of the results of the interim periods presented herein. All adjustments reflected in the unaudited condensed consolidated financial information are of a normal recurring nature unless indicated. The results for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.
Recently Adopted and Recently Issued Accounting Standards
In March 2020, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this ASU during the first quarter of 2022 in connection with amending Wesco's credit facilities, as disclosed in Note 7, "Debt". The replacement of London Interbank Offered Rate ("LIBOR") and the related adoption of the optional guidance under this accounting standard did not have a material impact on the Company's consolidated financial statements and notes thereto.
In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC Topic 606, Revenue from Contracts with Customers, as if the acquirer had originated the contracts. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Management is currently evaluating the impact that the adoption of this accounting standard will have on its consolidated financial statements and notes thereto.
In September 2022, the FASB issued ASU 2022-04, Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, which requires that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program's nature, activity during the period, changes from period to period, and potential magnitude. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. Management is currently evaluating the impact that the adoption of this accounting standard will have on its consolidated financial statements and notes thereto.
Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to Wesco’s financial position, results of operations or cash flows.

(1) No individual country's net sales are greater than 10% of total net sales.
(2) Wesco attributes revenues from external customers to individual countries on the basis of point of sale.
Due to the terms of certain contractual arrangements, Wesco bills or receives payment from its customers in advance of satisfying the respective performance obligation. Such advance billings or payments are recorded as deferred revenue and recognized as revenue when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Deferred revenue is usually recognized within a year or less from the date of the advance billing or payment. At September 30, 2022 and December 31, 2021, $55.5 million and $35.5 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Condensed Consolidated Balance Sheets.
The Company also has certain long-term contractual arrangements where revenue is recognized over time based on the cost-to-cost input method. As of September 30, 2022 and December 31, 2021, the Company had contract assets of $38.6 million and $33.4 million, respectively, resulting from arrangements where the amount of revenue recognized exceeded the amount billed to the customer. Contract assets are recorded in the Condensed Consolidated Balance Sheets as a component of prepaid expenses and other current assets.
Wesco’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns and discounts. Wesco measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data, as well as current and forecasted information. Variable consideration is reviewed by management on a monthly basis and revenue is adjusted accordingly. Variable consideration reduced revenue for the three months ended September 30, 2022 and 2021 by approximately $120.5 million and $85.8 million, respectively, and by approximately $324.1 million and $246.9 million for the nine months ended September 30, 2022 and 2021, respectively. The variable consideration for the three and nine months ended September 30, 2021 reflect adjustments that reduced the previously disclosed amounts by $9.7 million and $27.8 million, respectively. As of September 30, 2022 and December 31, 2021, the Company's estimated product return obligation was $45.5 million and $38.8 million, respectively.
Billings to customers for shipping and handling are recognized in net sales. Wesco has elected to recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, general and administrative expenses totaled $77.9 million and $63.5 million for the three months ended September 30, 2022 and 2021, respectively, and $222.0 million and $179.5 million for the nine months ended September 30, 2022 and 2021, respectively.

5. STOCK-BASED COMPENSATION
Wesco’s stock-based compensation awards are comprised of stock options, stock-settled stock appreciation rights, restricted stock units and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock options and stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units and performance-based awards with performance conditions is determined by the grant-date closing price of Wesco’s common stock. The forfeiture assumption is based on Wesco’s historical participant behavior that is reviewed on an annual basis. No dividends are assumed. For stock options and stock-settled stock appreciation rights that are exercised, and for restricted stock units and performance-based awards that vest, shares are issued out of Wesco's outstanding common stock.
Stock options and stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Restricted stock unit awards granted in February 2020 and prior vest based on a minimum time period of three years. The special award described below vests in tranches. Restricted stock units awarded in 2022 and 2021 vest ratably over a three-year period on each of the first, second and third anniversaries of the grant date. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels. Outstanding awards would vest upon the consummation of a change in control transaction with performance-based awards vesting at the target level.
On July 2, 2020, a special award of restricted stock units was granted to certain officers of the Company. These awards vest in tranches of 30% on each of the first and second anniversaries of the grant date and 40% on the third anniversary of the grant date, subject, in each case, to continued employment through the applicable anniversary date.
Performance-based awards granted in 2022, 2021 and 2020 are based on two equally-weighted performance measures: the three-year average growth rate of Wesco's net income attributable to common stockholders and the three-year cumulative return on net assets. These awards are accounted for as awards with performance conditions; compensation cost is recognized over the performance period based upon Wesco's determination of whether it is probable that the performance targets will be achieved.
During the three and nine months ended September 30, 2022 and 2021, Wesco granted the following stock options, stock-settled stock appreciation rights, restricted stock units and performance-based awards at the following weighted-average fair values:

| Three Months Ended |  | Nine Months Ended
| September 30, 2022 |  | September 30, 2021 |  | September 30, 2022 |  | September 30, 2021

The fair values of stock options and stock-settled stock appreciation rights, as disclosed in the table above, were estimated using the following weighted-average assumptions in the respective periods:

| Three Months Ended |  | Nine Months Ended
| September 30, 2022 |  | September 30, 2021 |  | September 30, 2022 |  | September 30, 2021
Risk free interest rate | 2.9 | % |  | n/a |  | 2.0 | % |  | 0.8 | %
Expected life (in years) | 7 |  | n/a |  | 7 |  | 7
Expected volatility | 44 | % |  | n/a |  | 43 | % |  | 41 | %

The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve as of the grant date.

6. EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of equity awards.

Accounts Receivable Securitization Facility
On March 1, 2022, WESCO Distribution, Inc. (“Wesco Distribution”) amended its accounts receivable securitization facility (the “Receivables Facility”) pursuant to the terms and conditions of a Fourth Amendment to Fifth Amended and Restated Receivables Purchase Agreement (the “Fourth Receivables Amendment”), by and among WESCO Receivables Corp., Wesco Distribution, the various purchaser groups from time to time party thereto and PNC Bank, National Association, as administrator. The Fourth Receivables Amendment modified the receivables purchase agreement entered into on June 22, 2020 (the “Receivables Purchase Agreement”). The Fourth Receivables Amendment, among other things, (i) increased the purchase limit under the Receivables Facility from $1,300 million to $1,400 million, (ii) increased the aggregate commitment from $1,500 million to $1,750 million under an accordion feature that permits requests to increase the purchase limit, and (iii) extended the maturity date from June 1, 2024 to March 1, 2025. Additionally, the Fourth Receivables Amendment replaced the LIBOR interest rate option with Secured Overnight Financing Rate-based (“SOFR”) interest rate options, including term SOFR and daily simple SOFR, and decreased the interest rate spread from 1.15% to 1.10%. The commitment fee of the Receivables Facility were unchanged.
On August 2, 2022, Wesco Distribution further amended its Receivables Facility pursuant to the terms and conditions of a Fifth Amendment to Fifth Amended and Restated Receivables Purchase Agreement (the “Fifth Receivables Amendment”). The Fifth Receivables Amendment amends the Receivables Purchase Agreement to, among other things, increase the purchase limit under the Receivables Facility from $1,400 million to $1,525 million and to decrease the interest rate spread from 1.10% to 1.05%. The maturity date and commitment fee of the Receivables Facility were unchanged.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)
(unaudited)
Under the Receivables Facility, Wesco Distribution sells, on a continuous basis, an undivided interest in all domestic accounts receivable to Wesco Receivables, a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest in the receivables, in the form of overcollateralization. Since Wesco Distribution maintains control of the transferred receivables, the transfers do not qualify for “sale” treatment. As a result, the transferred receivables remain on the balance sheet, and Wesco recognizes the related secured borrowing. Wesco Distribution has agreed to continue servicing the sold receivables for the third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.
Revolving Credit Facility
On March 1, 2022, Wesco Distribution amended its revolving credit facility (the “Revolving Credit Facility”) pursuant to the terms and conditions of a Second Amendment to Fourth Amended and Restated Credit Agreement (the “Second Revolver Amendment”), by and among Wesco Distribution, as the borrower representative, the other U.S. borrowers party thereto, WESCO Distribution Canada LP, the other Canadian borrowers party thereto, WESCO International, the lenders party thereto and Barclays Bank PLC, as the administrative agent. The Second Revolver Amendment modified the revolving credit facility entered into on June 22, 2020 (the "Revolving Credit Agreement"). The Second Revolver Amendment, among other things, (i) increased the revolving commitments under the Revolving Credit Facility from $1,200 million to $1,350 million, (ii) increased the sub-facility for loans denominated in Canadian dollars from $500 million to $550 million, (iii) increased the capacity to request increases in the aggregate revolving commitments from $400 million to $650 million, (iv) modified certain negative covenants to provide for additional flexibility, and (v) extended the maturity date from June 22, 2025 to March 1, 2027. Additionally, the Second Revolver Amendment replaced the LIBOR-based interest rate option with SOFR-based interest rate options, including term SOFR and daily simple SOFR. The applicable interest rate for borrowings under the Revolving Credit Facility, as amended, includes interest rate spreads based on available borrowing capacity that range from 1.00% to 1.50% for SOFR-based borrowings and from 0.00% to 0.50% for prime rate-based borrowings.
On August 2, 2022, Wesco Distribution further amended its Revolving Credit Facility pursuant to the terms and conditions of a Third Amendment to Fourth Amended and Restated Credit Agreement (the “Third Revolver Amendment”). The Third Revolver Amendment amends the Revolving Credit Agreement to, among other things, increase the revolving commitments under the Revolving Credit Facility from $1,350 million to $1,525 million and to increase the sub-facility for loans denominated in Canadian dollars from $550 million to $600 million. The maturity date and interest rate spreads of the Revolving Credit Facility were unchanged.
8. EMPLOYEE BENEFIT PLANS
Defined Contribution Plans
Wesco Distribution sponsors a defined contribution retirement savings plan for the majority of its U.S. employees (the "WESCO Distribution, Inc. Retirement Savings Plan"). Effective January 1, 2022, the defined contribution plan covering all of Anixter Inc.'s non-union U.S. employees (the "Anixter Inc. Employee Savings Plan") was merged with and into the WESCO Distribution, Inc. Retirement Savings Plan (the "U.S. Defined Contribution Plan Merger"). On December 31, 2021, participant account balances were transferred from the Anixter Inc. Employee Savings Plan to the WESCO Distribution, Inc. Retirement Savings Plan. In connection with the U.S. Defined Contribution Plan Merger, the WESCO Distribution, Inc. Retirement Savings Plan was amended to change the employer matching contribution at an amount equal to 100% of a participant's eligible elective deferrals up to 3% of the participant's eligible compensation and 50% of the next 4% of eligible compensation, and to eliminate discretionary employer contributions.
WESCO Distribution Canada LP, a wholly-owned subsidiary of the Company, sponsors a defined contribution plan covering the current full-time employees of WESCO Distribution Canada LP and part-time employees meeting certain requirements for continuous service, earnings and minimum hours of employment (the "Wesco Canadian Defined Contribution Plan"). Effective January 1, 2022, the defined contribution plan for certain employees of Anixter Canada Inc. and Anixter Power Solutions Canada Inc. (the "Anixter Canadian Defined Contribution Plan") was merged with and into an amended Wesco Canadian Defined Contribution Plan. During the first quarter of 2022, participant account balances were transferred from the Anixter Canadian Defined Contribution Plan to the amended Wesco Canadian Defined Contribution Plan. The amended Wesco Canadian Defined Contribution Plan provides a core employer contribution of 3% of a participant's eligible compensation, plus a matching contribution equal to 50% of a participant's elective contributions up to 4% of eligible compensation (for a maximum total employer contribution equal to 5%). The amended Wesco Canadian Defined Contribution Plan also requires employees of EECOL Electric Corp. hired on or after January 1, 2022 to join this Canadian defined contribution plan, and permits enrollment for those not participating in the defined benefit plan described below.

Wesco incurred charges of $12.4 million and $16.4 million for the three months ended September 30, 2022 and 2021, respectively, and $45.4 million and $49.1 million for the nine months ended September 30, 2022 and 2021, respectively, for all defined contribution plans.
Deferred Compensation Plans
Wesco Distribution sponsors a non-qualified deferred compensation plan (the "Wesco Deferred Compensation Plan") that permits select employees to make pre-tax deferrals of salary and bonus. Employees have the option to transfer balances allocated to their accounts in the Wesco Deferred Compensation Plan into any of the available investment options. The Wesco Deferred Compensation Plan is an unfunded plan. As of September 30, 2022 and December 31, 2021, the Company's obligation under the Wesco Deferred Compensation Plan was $19.6 million and $20.9 million, respectively, which is included in other noncurrent liabilities in the Condensed Consolidated Balance Sheets.
Defined Benefit Plans
Wesco sponsors a contributory defined benefit plan covering substantially all Canadian employees of EECOL Electric Corp., a wholly-owned subsidiary of the Company (the "EECOL Plan") and a Supplemental Executive Retirement Plan for certain executives of EECOL Electric Corp. (the "EECOL SERP").
Anixter Inc. sponsors the Anixter Inc. Pension Plan, which was closed to entrants first hired or rehired on or after July 1, 2015, and various defined benefit pension plans covering employees of foreign subsidiaries in Canada and Europe (together with the "EECOL Plan" and "EECOL SERP", the "Foreign Plans"). The majority of the Company's defined benefit pension plans are non-contributory, and with the exception of the U.S. and Canada, cover substantially all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in each of the plan agreements. The Anixter Inc. Pension Plan is funded as required by the Employee Retirement Income Security Act of 1974 and the Internal Revenue Service. With the exception of the EECOL SERP, which is an unfunded plan, the Foreign Plans are funded as required by applicable foreign laws.
During the fourth quarter of 2021, the Company adopted certain plan amendments to: (i) freeze the benefits provided under the Anixter Inc. Pension Plan effective December 31, 2021, (ii) close participation in the EECOL Plan and EECOL SERP effective December 31, 2021, and (iii) freeze the benefit accruals under the Pension Plan for Employees of Anixter Canada Inc., the EECOL Plan and the EECOL SERP effective December 31, 2023.
The Company expects to contribute approximately $10.8 million to its Foreign Plans in 2022, of which approximately $9.3 million was contributed during the nine months ended September 30, 2022. The Company does not expect to make a contribution to its domestic qualified pension plan in 2022 due to its overfunded status.

Other Benefits
Prior to its acquisition by Wesco on June 22, 2020, Anixter granted restricted stock units in the ordinary course of business to its employees and directors. These awards, for which vesting did not accelerate solely as a result of the Company's merger with Anixter, were converted into cash-only settled Wesco phantom stock units, which vest ratably over a 3-year period. As of September 30, 2022 and December 31, 2021, the estimated fair value of these awards was $7.9 million and $22.7 million, respectively.
As of September 30, 2022, the Company's liability for these awards is $7.1 million, which is included in accrued payroll and benefit costs in the Condensed Consolidated Balance Sheet. As of December 31, 2021, the Company's liability for these awards was $17.3 million, of which $10.9 million was included in accrued payroll and benefit costs and $6.4 million was a component of other noncurrent liabilities in the Condensed Consolidated Balance Sheet.
The Company recognized compensation expense associated with these awards of $1.8 million and $3.4 million for the three months ended September 30, 2022 and 2021, respectively, and $1.6 million and $9.8 million for the nine months ended September 30, 2022 and 2021, respectively, which is reported as a component of selling, general and administrative expenses.
9. FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, bank overdrafts, outstanding indebtedness, foreign currency forward contracts, and benefit plan assets. Except for benefit plan assets, outstanding indebtedness and foreign currency forward contracts, the carrying value of the Company’s remaining financial instruments approximates fair value.
18

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)
(unaudited)
The assets of the Company's various defined benefit plans are primarily comprised of common/collective/pool funds (i.e., mutual funds). These funds are valued at the net asset value (NAV) of shares held in the underlying funds. Investments for which fair value is measured using the NAV per share practical expedient are not classified in the fair value hierarchy.
The Company uses a market approach to determine the fair value of its debt instruments, utilizing quoted prices in active markets, interest rates and other relevant information generated by market transactions involving similar instruments. Therefore, the inputs used to measure the fair value of the Company's debt instruments are classified as Level 2 within the fair value hierarchy.
The carrying value of Wesco's debt instruments with fixed interest rates was $2,881.1 million and $2,880.7 million as of September 30, 2022 and December 31, 2021, respectively. The estimated fair value of this debt was $2,866.5 million and $3,118.0 million as of September 30, 2022 and December 31, 2021, respectively. The reported carrying values of Wesco's other debt instruments, including those with variable interest rates, approximated their fair values as of September 30, 2022 and December 31, 2021.
The Company purchases foreign currency forward contracts to minimize the effect of fluctuations in foreign currency-denominated accounts on its earnings. The foreign currency forward contracts are not designated as hedges for accounting purposes. The Company's strategy is to negotiate terms for its derivatives and other financial instruments to be highly effective, such that the change in the value of the derivative offsets the impact of the underlying hedge. Its counterparties to foreign currency forward contracts have investment-grade credit ratings. The Company regularly monitors the creditworthiness of its counterparties to ensure no issues exist that could affect the value of its derivatives.
The Company does not hedge 100% of its foreign currency-denominated accounts. In addition, the results of hedging can vary significantly based on various factors, such as the timing of executing foreign currency forward contracts versus the movement of currencies, as well as fluctuations in the account balances throughout each reporting period. The fair value of foreign currency forward contracts is based on the difference between the contract rate and the current price of a forward contract with an equivalent remaining term. The fair value of foreign currency forward contracts is measured using observable market information. These inputs are considered Level 2 in the fair value hierarchy. At September 30, 2022 and December 31, 2021, foreign currency forward contracts were revalued at then-current foreign exchange rates with the changes in valuation reflected directly in other non-operating income (expense) in the Condensed Consolidated Statements of Income and Comprehensive Income offsetting the transaction gain (loss) recorded on foreign currency-denominated accounts. At September 30, 2022 and December 31, 2021, the gross and net notional amounts of foreign currency forward contracts outstanding were approximately $224.3 million and $188.6 million, respectively. While all of the Company's foreign currency forward contracts are subject to master netting arrangements with its counterparties, assets and liabilities related to these contracts are presented on a gross basis within the Condensed Consolidated Balance Sheets. The gross fair value of assets and liabilities related to foreign currency forward contracts were immaterial.
10. COMMITMENTS AND CONTINGENCIES
From time to time, a number of lawsuits and claims have been or may be asserted against the Company relating to the conduct of its business, including litigation relating to commercial, product and employment matters (including wage and hour). The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to Wesco. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on Wesco's financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on Wesco's results of operations for that period.

The effective tax rate for the three and nine months ended September 30, 2022 was 26.3% and 24.0%, respectively. The effective tax rate for the three and nine months ended September 30, 2021 was 27.2% and 22.0%, respectively. Wesco’s effective tax rate typically differs from the federal statutory income tax rate due to the tax effect of intercompany financing, foreign tax rate differences, the U.S. taxes imposed on foreign income, nondeductible expenses and state income taxes. For the three months ended September 30, 2022 and 2021, the effective tax rate reflects discrete income tax benefits of $3.2 million and $3.3 million, respectively, resulting from the exercise and vesting of stock-based awards. These discrete income tax benefits were offset by discrete income tax expense of $0.8 million and $4.2 million, respectively, resulting from return-to-provision adjustments. The net impact of discrete income tax items was a reduction to the estimated annual effective tax rate of approximately 0.7 percentage points for the three months ended September 30, 2022 and an increase of 0.7 percentage points for the three months ended September 30, 2021. For the nine months ended September 30, 2022 and 2021, the effective tax rate reflects discrete income tax benefits of $13.4 million and $8.3 million, respectively, resulting from reductions to the valuation allowance recorded against foreign tax credit carryforwards, as well as the exercise and vesting of stock-based awards of $9.4 million and $7.8 million, respectively. These discrete income tax benefits were partially offset by discrete income tax expense of $0.8 million and $4.2 million, respectively, resulting from return-to-provision adjustments. The net impact of discrete income tax items was a reduction to the estimated annual effective tax rate in such periods of approximately 2.6 and 3.1 percentage points, respectively.
There have been no material adjustments to liabilities for uncertain tax positions since December 31, 2021.
12. BUSINESS SEGMENTS
The Company has operating segments comprising three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The Company's chief operating decision maker evaluates the performance of its operating segments based primarily on net sales, adjusted earnings before interest, taxes, depreciation and amortization ("EBITDA"), and adjusted EBITDA margin percentage.
The Company incurs corporate costs primarily related to treasury, tax, information technology, legal and other centralized functions. The Company also has various corporate assets. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are either not allocated to the segments or reviewed on a segment basis. Corporate expenses and assets not directly identifiable with a reportable segment are reported in the tables below to reconcile the reportable segments to the consolidated financial statements.

Note: Adjusted EBITDA and Adjusted EBITDA margin % are non-GAAP financial measures that provide indicators of the Company's performance and its ability to meet debt service requirements. Adjusted EBITDA is defined as EBITDA before other non-operating expenses (income), non-cash stock-based compensation expense, merger-related and integration costs, and net gain on the divestiture of Wesco's legacy utility and data communications businesses in Canada. Adjusted EBITDA margin % is calculated by dividing Adjusted EBITDA by net sales.
13. SUBSEQUENT EVENTS
On October 27, 2022, the Company provided notice to participants in the Anixter Inc. Pension Plan of its intention to terminate such plan effective December 31, 2022. The Company will incorporate certain estimates that reflect the pending settlement in the assumptions used to measure the projected benefit obligation associated with this plan at the next measurement date as of December 31, 2022. The Company does not expect the termination to result in any curtailment gain or loss as the Anixter Inc. Pension Plan had previously been frozen during the fourth quarter of 2021. The Company anticipates that the assets held by the plan are sufficient to satisfy all benefit obligations upon termination.
On October 31, 2022, Wesco Distribution amended its Receivables Facility to increase the purchase limit from $1,525 million to $1,625 million.
Also on October 31, 2022, Wesco Distribution amended its Revolving Credit Facility to increase the revolving commitments from $1,525 million to $1,725 million and to increase the sub-facility for loans denominated in Canadian dollars from $600 million to $625 million.
On November 1, 2022, through its wholly-owned subsidiary Wesco Distribution, the Company closed its acquisition of Rahi Systems Holdings, Inc., a leading provider of global hyperscale data center solutions headquartered in Fremont, California. Wesco funded the purchase price paid at closing of $217 million with cash, and borrowings under the Receivables Facility and the Revolving Credit Facility. Due to the timing of the close of the acquisition, the Company will complete its preliminary purchase price allocation during the fourth quarter of 2022.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion should be read in conjunction with the information in the unaudited condensed consolidated financial statements and notes thereto included in Item 1 of this Quarterly Report on Form 10-Q and WESCO International, Inc.’s audited Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021. The matters discussed herein may contain forward-looking statements that are subject to certain risks and uncertainties that could cause actual results to differ materially from expectations. Certain of these risks are set forth in Item 1A of WESCO International, Inc.'s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as well as WESCO International, Inc.’s other reports filed with the Securities and Exchange Commission (the "SEC"). In this Item 2, "Wesco" refers to WESCO International, Inc., and its subsidiaries and its predecessors unless the context otherwise requires. References to "we," "us," "our" and the "Company" refer to Wesco and its subsidiaries.
In addition to the results provided in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), our discussion and analysis of financial condition and results of operations includes certain non-GAAP financial measures, which are defined further below. These financial measures include organic sales growth, earnings before interest, taxes, depreciation and amortization ("EBITDA"), adjusted EBITDA, adjusted EBITDA margin, financial leverage, adjusted selling, general and administrative expenses, adjusted income from operations, adjusted provision for income taxes, adjusted income before income taxes, adjusted net income, adjusted net income attributable to WESCO International, Inc., adjusted net income attributable to common stockholders, and adjusted earnings per diluted share. We believe that these non-GAAP measures are useful to investors as they provide a better understanding of our financial condition and results of operations on a comparable basis. Additionally, certain non-GAAP measures either focus on or exclude items impacting comparability of results, allowing investors to more easily compare our financial performance from period to period. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated above.
Company Overview
Wesco, headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.
We employ more than 18,000 people, maintain relationships with approximately 45,000 suppliers, and serve approximately 140,000 customers worldwide. With nearly 1,500,000 products, end-to-end supply chain services, and extensive digital capabilities, we provide innovative solutions to meet customer needs across commercial and industrial businesses, contractors, government agencies, institutions, telecommunications providers, and utilities. Our innovative value-added solutions include supply chain management, logistics and transportation, procurement, warehousing and inventory management, as well as kitting and labeling, limited assembly of products and installation enhancement. We have approximately 800 branches, warehouses and sales offices with operations in more than 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and multi-national corporations.
In 2021, we established a new corporate brand strategy to adopt a single, master brand architecture. This initiative reflects our corporate integration strategy and simplifies engagement for our customers and suppliers. As a result, we have been migrating certain legacy sub-brands to the master brand architecture, a process that will continue for the next several years. Due to the strength of its recognition with customers and suppliers, we will continue to use the Anixter brand name as part of the master brand strategy for the foreseeable future.
We have operating segments comprising three strategic business units consisting of Electrical & Electronic Solutions ("EES"), Communications & Security Solutions ("CSS") and Utility & Broadband Solutions ("UBS"). These operating segments are equivalent to our reportable segments. The following is a description of each of our reportable segments and their business activities.
Electrical & Electronic Solutions
The EES segment, with over 6,400 employees supporting customers in over 50 countries, supplies a broad range of products and solutions primarily to the construction, industrial, and original equipment manufacturer ("OEM") markets. The product portfolio in this business includes a broad range of electrical equipment and supplies, automation and connected devices (the "Internet of Things" or "IoT"), security, lighting, wire and cable, safety, and maintenance, repair and operating ("MRO") products from industry-leading manufacturing partners. The EES service portfolio includes contractor solutions to improve project execution, direct and indirect manufacturing supply chain optimization programs, lighting and renewables advisory services, and digital and automation solutions to improve safety and productivity.
24

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
Communications & Security Solutions
The CSS segment, with over 3,300 employees supporting customers in over 50 countries, is a global leader in the network infrastructure and security markets. CSS sells products directly to end-users or through various channels including data communications contractors, security, network, professional audio/visual and systems integrators. In addition to the core network infrastructure and security portfolio, CSS has a broad offering of safety and energy management solutions. CSS products are often combined with supply chain services to increase efficiency and productivity, including installation enhancement, project deployment, advisory, and IoT and digital services.
Utility & Broadband Solutions
The UBS segment, with over 2,400 employees supporting customers primarily in the U.S. and Canada, provides products and services to investor-owned utilities, public power companies, including municipalities, as well as global service providers, wireless providers, broadband operators and the contractors that service these customers. The UBS segment also includes our integrated supply business, which provides products and services to large industrial and commercial end-users to support their MRO spend. The products sold into the utility and broadband markets include wire and cable, transformers, transmission and distribution hardware, switches, protective devices, connectors, lighting, conduit, fiber and copper cable, connectivity products, pole line hardware, racks, cabinets, safety and MRO products, and point-to-point wireless devices. The UBS segment also offers a complete set of service solutions to improve customer supply chain efficiencies.
Overall Financial Performance
Our financial results for the first nine months of 2022 compared to the first nine months of 2021 reflect double-digit sales growth driven by the benefits of increased scale, secular growth trends and the execution of our cross-sell program, as well as margin expansion and the realization of integration synergies, partially offset by higher selling, general and administrative ("SG&A") payroll and payroll-related expenses consisting of salaries and variable compensation, volume-related costs, along with expenses associated with our digital transformation initiatives.
Net sales for the first nine months of 2022 increased $2.5 billion, or 18.7%, over the corresponding prior year period. The increase reflects price inflation, continued strong demand, secular growth trends, and execution of our cross-sell program, partially offset by the negative impact of fluctuations in foreign exchange rates. Cost of goods sold as a percentage of net sales was 78.3% and 79.2% for the first nine months of 2022 and 2021, respectively. The improvement of 90 basis points reflects our focus on value-driven pricing and pass-through of inflationary costs, along with the continued momentum of our gross margin improvement program. Cost of goods sold for the first nine months of 2021 included a write-down to the carrying value of certain personal protective equipment inventories, which increased cost of goods sold as a percentage of net sales by approximately 20 basis points.
Income from operations was $1.1 billion for the first nine months of 2022 compared to $0.6 billion for the first nine months of 2021, an increase of $474.7 million, or 81.6%. Income from operations as a percentage of net sales was 6.7% for the current nine-month period, compared to 4.4% for the first nine months of the prior year. Income from operations for the first nine months of 2022 includes merger-related and integration costs of $52.2 million. Additionally, in connection with an integration initiative to review our brand strategy, certain legacy trademarks are migrating to a master brand architecture, which resulted in $9.4 million of accelerated amortization expense for the nine months ended September 30, 2022. Adjusted for these amounts, income from operations was 7.0% of net sales. For the first nine months of 2021, income from operations adjusted for merger-related and integration costs of $119.8 million, accelerated trademark amortization expense of $20.2 million, and a net gain of $8.9 million resulting from the divestiture of our legacy utility and data communications businesses in Canada during the first quarter of 2021 was 5.3% of net sales. For the nine months ended September 30, 2022, income from operations compared to the prior year improved across all segments and reflects sales growth and lower cost of goods sold as a percentage of net sales, as well as the realization of integration synergies. Income from operations for the first nine months of 2022 was negatively impacted by higher SG&A payroll and payroll-related expenses consisting of salaries and variable compensation, as well as higher volume-related costs and expenses associated with our digital transformation initiatives.
Earnings per diluted share for the first nine months of 2022 was $11.42, based on 52.4 million diluted shares, compared to $4.91 for the first nine months of 2021, based on 51.9 million diluted shares. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, earnings per diluted share for the first nine months of 2022 was $12.29. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, net gain on Canadian divestitures, and the related income tax effects, earnings per diluted share for the first nine months of 2021 was $6.80. Adjusted earnings per diluted share increased 80.7% year-over-year.
25

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
During the first nine months of 2022, we continued to experience strong demand from many of our customers. We also continued to experience some delays in receiving products from our suppliers. We believe that the impact of these supply chain issues on our net sales for the third quarter of 2022 was consistent with the first and second quarters of the year. We are aggressively managing supply chain issues, which includes increasing inventory levels to service our customers. Our industry and the broader economy are experiencing supply chain challenges, including product delays and backlogged orders, shortages in raw materials and components, labor shortages, transportation challenges, and higher costs. We anticipate that these supply chain challenges, as well as inflationary pressures, will continue for the remainder of 2022 and may extend into 2023. We intend to continue to actively manage the impact of inflation on our results of operations. We cannot reasonably estimate possible future impacts from these disruptions at this time.
There continues to be ongoing uncertainties associated with the COVID-19 pandemic, including with respect to economic conditions and the possible resurgence of COVID-19 whether through the emergence of new variants of the virus or otherwise. As the duration and severity of the COVID-19 pandemic cannot be predicted, there is significant uncertainty as to the ultimate impact that COVID-19 will have on our business, results of operations and financial condition.
Cash Flow
Operating cash flow for the first nine months of 2022 was an outflow of $410.6 million. Net cash used in operating activities included net income of $643.0 million and non-cash adjustments to net income totaling $193.1 million, which were primarily comprised of depreciation and amortization of $135.6 million, stock-based compensation expense of $34.4 million, amortization of debt discount and debt issuance costs of $11.6 million, and deferred income taxes of $7.2 million. Operating cash flow also included changes in assets and liabilities of $1.2 billion, which were primarily comprised of an increase in inventories of $886.3 million as a result of investments to address supply chain challenges and to support increases in our sales backlog, including project-based business, an increase in trade accounts receivable of $737.6 million resulting from higher sales, partially offset by an increase in accounts payable of $479.6 million due to the aforementioned higher purchases of inventory.
Investing activities primarily included $59.4 million of capital expenditures mostly consisting of internal-use computer software and information technology hardware to support our digital transformation initiatives, as well as equipment and leasehold improvements to support our global network of branches, warehouses and sales offices.
Financing activities were primarily comprised of borrowings and repayments of $2.8 billion and $2.5 billion, respectively, related to our revolving credit facility (the "Revolving Credit Facility"), and borrowings and repayments of $380.0 million and $125.0 million, respectively, related to our accounts receivable securitization facility (the "Receivables Facility"). Financing activities for the first nine months of 2022 also included $43.1 million of dividends paid to holders of our Series A Preferred Stock, $25.0 million of payments for taxes related to the exercise and vesting of stock-based awards, and net proceeds from our various international lines of credit of approximately $0.2 million.
Financing Availability
During the first and third quarters of 2022 we amended our Receivables Facility and Revolving Credit Facility to, among other things, increase their borrowing capacities, extend their maturity dates, and replace London Inter-Bank Offered Rate-based (“LIBOR”) interest rate options with Secured Overnight Financing Rate-based (“SOFR”) interest rate options.
See Note 7, "Debt" of our Notes to the unaudited Condensed Consolidated Financial Statements for additional disclosure regarding the amendments to these facilities.
As of September 30, 2022, we had $600.3 million in total available borrowing capacity under our Revolving Credit Facility, which matures in March 2027.

Note: Organic sales growth is a non-GAAP financial measure of sales performance. Organic sales growth is calculated by deducting the percentage impact from acquisitions and divestitures for one year following the respective transaction, fluctuations in foreign exchange rates and number of workdays from the reported percentage change in consolidated net sales.
Net sales were $5.4 billion for the third quarter of 2022 compared to $4.7 billion for the third quarter of 2021, an increase of 15.2%, reflecting price inflation, continued strong demand, secular growth trends, and the execution of our cross-sell program. Organic sales for the third quarter of 2022 grew by 16.9% as fluctuations in foreign exchange rates negatively impacted reported net sales by 1.7%. All segments reported increased sales versus the prior year period, as described below. For the three months ended September 30, 2022, pricing related to inflation favorably impacted our net sales by approximately 8%.
EES reported net sales of $2.2 billion for the third quarter of 2022 compared to $2.0 billion for the third quarter of 2021, an increase of 12.7%. Organic sales for the third quarter of 2022 grew by 14.9% as fluctuations in foreign exchange rates negatively impacted reported net sales by 2.2%. The increase reflects price inflation and strong end market demand, partially offset by the effect of supply chain constraints and commodity prices.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
CSS reported net sales of $1.6 billion for the third quarter of 2022 compared to $1.5 billion for the third quarter of 2021, an increase of 7.6%. Organic sales for the third quarter of 2022 grew by 9.6% as fluctuations in foreign exchange rates negatively impacted reported net sales by 2.0%. The increase reflects price inflation, growth in our security solutions and network infrastructure businesses, as well as and the benefits of cross selling, partially offset by the effect of supply chain constraints.
UBS reported net sales of $1.6 billion for the third quarter of 2022 compared to $1.3 billion for the third quarter of 2021, an increase of 28.0%. Organic sales for the third quarter of 2022 grew by 28.6% as fluctuations in foreign exchange rates negatively impacted reported net sales by 0.6%. The increase reflects price inflation, broad-based growth driven by investments in electrification, green energy, grid modernization and hardening, and rural broadband development, as well as expansion in our integrated supply business.
Cost of Goods Sold
Cost of goods sold for the third quarter of 2022 was $4.2 billion compared to $3.7 billion for the third quarter of 2021, an increase of $521.1 million. Cost of goods sold as a percentage of net sales was 77.9% and 78.7% for the third quarter of 2022 and 2021, respectively. The favorable reduction of 80 basis points reflects our focus on value-driven pricing and pass-through of inflationary costs, along with the continued momentum of our gross margin improvement program. The third quarter of 2021 included a write-down to the carrying value of certain personal protective equipment inventories, which increased cost of goods sold as a percentage of net sales by approximately 10 basis points.
Selling, General and Administrative Expenses
SG&A expenses primarily include payroll and payroll-related costs, shipping and handling, travel and entertainment, facilities, utilities, information technology expenses, professional and consulting fees, credit losses, gains (losses) on the sale of property and equipment, as well as real estate and personal property taxes. SG&A expenses for the third quarter of 2022 totaled $760.2 million versus $721.8 million for the third quarter of 2021, an increase of $38.4 million, or 5.3%. As a percentage of net sales, SG&A expenses were 14.0% and 15.3% for the third quarter of 2022 and 2021, respectively. SG&A expenses for the third quarter of 2022 include merger-related and integration costs of $13.2 million. Adjusted for this amount, SG&A expenses were $747.0 million, or 13.7% of net sales, for the third quarter of 2022. SG&A expenses for the third quarter of 2021 include $35.8 million of merger-related and integration costs. Adjusted for this amount, SG&A expenses were $686.0 million, or 14.5% of net sales, for the third quarter of 2021.
SG&A payroll and payroll-related expenses for the third quarter of 2022 of $481.7 million increased by $15.8 million compared to the same period in 2021 primarily due to higher salaries.
SG&A expenses not related to payroll and payroll-related costs for the third quarter of 2022 were $278.5 million compared to $255.9 million for the same period in 2021. The increase of $22.6 million primarily reflects higher volume-related costs driven by significant sales growth and digital transformation initiatives that contributed to higher expenses in the third quarter of 2022. These increases were partially offset by the realization of integration cost synergies, as well as lower professional and consulting fees associated with integration activities.
Depreciation and Amortization
Depreciation and amortization decreased $14.0 million to $42.7 million for the third quarter of 2022 compared to $56.7 million for the third quarter of 2021. The third quarter of 2022 and 2021 includes $0.4 million and $15.1 million, respectively, resulting from changes in the estimated useful lives of certain legacy trademarks that are migrating to our master brand architecture, as described above. As of September 30, 2022, we expect to recognize approximately $0.4 million of amortization expense for trademarks migrating to our master brand architecture over the remainder of 2022 and $5.3 million thereafter.

Income from operations was $401.6 million for the third quarter of 2022 compared to $229.5 million for the third quarter of 2021. The increase of $172.1 million, or 75.0%, reflects sales growth and lower cost of goods sold as a percentage of net sales, along with the realization of integration synergies, partially offset by higher SG&A payroll and payroll-related expenses, volume-related costs, as well as expenses associated with our digital transformation initiatives. Income from operations for the third quarter of 2022 was not materially affected by higher pricing related to inflation given the offsetting effect of higher costs for certain products.
EES reported income from operations of $213.2 million for the third quarter of 2022 compared to $155.2 million for the third quarter of 2021. The increase of $58.0 million primarily reflects the factors impacting the overall business, as described above.
CSS reported income from operations of $139.0 million for the third quarter of 2022 compared to $108.2 million for the third quarter of 2021. The increase of $30.8 million primarily reflects the factors impacting the overall business, as described above, as well as the negative impact of approximately 20 basis points from the prior year personal protective equipment inventory value write-down described in our overall results above.
UBS reported income from operations of $179.3 million for the third quarter of 2022 compared to $108.2 million for the third quarter of 2021. The increase of $71.1 million primarily reflects the factors impacting the overall business, as described above.
Corporate, which primarily incurs costs related to treasury, tax, information technology, legal and other centralized functions, recognized net expenses of $129.9 million for the third quarter of 2022 compared to $142.1 million for the third quarter of 2021. The decrease of $12.2 million primarily reflects a decrease in professional and consulting fees associated with integration activities.
Interest Expense, net
Net interest expense totaled $75.1 million for the third quarter of 2022 compared to $69.7 million for the third quarter of 2021. The increase reflects higher borrowings and an increase in variable interest rates.
Other Expense (Income), net
Other non-operating expense totaled $0.7 million for the third quarter of 2022 compared to other non-operating income of $5.3 million for the third quarter of 2021. As disclosed in Note 8, "Employee Benefit Plans" of our Notes to the unaudited Condensed Consolidated Financial Statements, we recognized net benefits of $3.4 million and $4.1 million associated with the non-service cost components of net periodic pension (benefit) cost for the three months ended September 30, 2022 and 2021, respectively. Due to fluctuations in the U.S. dollar against certain foreign currencies, we recognized a net foreign currency exchange loss of $4.4 million for the third quarter of 2022 compared to a net gain of $1.3 million for the third quarter of 2021.
Income Taxes
The provision for income taxes was $85.6 million for the third quarter of 2022 compared to $44.9 million for the corresponding quarter of the prior year, resulting in effective tax rates of 26.3% and 27.2%, respectively. The effective tax rate for the quarter ended September 30, 2022 was lower than the comparable prior year period due to the favorable net impact of discrete income tax items.

Net sales were $15.9 billion for the first nine months of 2022 compared to $13.4 billion for the first nine months of 2021, an increase of 18.7%, reflecting price inflation, continued strong demand, secular growth trends, and the execution of our cross-sell program. Organic sales for the first nine months of 2022 grew by 19.5% as the number of workdays positively impacted reported net sales by 0.5%, while fluctuations in foreign exchange rates and the divestiture of our legacy utility and data communications businesses in Canada in the first quarter of 2021 negatively impacted reported net sales by 1.2% and 0.1%, respectively. All segments reported increased sales versus the prior year period, as discussed below. For the first nine months of 2022, pricing related to inflation favorably impacted our net sales by approximately 8%.
EES reported net sales $6.7 billion for the first nine months of 2022 compared to $5.6 billion for the first nine months of 2021, an increase of 18.3%.

The increase reflects price inflation, expansion in our industrial, construction, and original equipment manufacturer businesses, as well as the benefits of cross selling and secular growth trends in electrification and automation, partially offset by the effect of supply chain constraints and commodity prices.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
CSS reported net sales of $4.6 billion for the first nine months of 2022 compared to $4.2 billion for the first nine months of 2021, an increase of 10.4%. Organic sales for the first nine months of 2022 grew by 11.5% as the number of workdays positively impacted reported net sales by 0.5% and fluctuations in foreign exchange rates negatively impacted reported net sales by 1.6%. The increase reflects strong growth in our security solutions and network infrastructure businesses, as well as price inflation and the benefits of cross selling, partially offset by the effect of supply chain constraints.
UBS reported net sales of $4.6 billion for the first nine months of 2022 compared to $3.5 billion for the first nine months of 2021, an increase of 29.1%. Organic sales for the first nine months of 2022 grew by 29.1% as the number of workdays positively impacted reported net sales by 0.5%, while fluctuations in foreign exchange rates and the Canadian divestitures described above negatively impacted reported net sales by 0.4% and 0.1%, respectively. The increase reflects price inflation, broad-based growth in our utility and broadband businesses, as well as expansion in our integrated supply business.
Cost of Goods Sold
Cost of goods sold for the first nine months of 2022 was $12.4 billion compared to $10.6 billion for the first nine months of 2021, an increase of $1.8 billion. Cost of goods sold as a percentage of net sales was 78.3% for the first nine months of 2022 compared to 79.2% for the first nine months of 2021. The favorable reduction of 90 basis points reflects our focus on value-driven pricing and pass-through of inflationary costs, along with the continued momentum of our gross margin improvement program. The first nine months of 2021 included a write-down to the carrying value of certain personal protective equipment inventories, which increased cost of goods sold as a percentage of net sales by approximately 20 basis points.
Selling, General and Administrative Expenses
SG&A expenses primarily include payroll and payroll-related costs, shipping and handling, travel and entertainment, facilities, utilities, information technology expenses, professional and consulting fees, credit losses, gains (losses) on the sale of property and equipment, as well as real estate and personal property taxes. SG&A expenses for the first nine months of 2022 totaled $2.3 billion versus $2.1 billion for the first nine months of 2021, an increase of $193.2 million, or 9.4%. As a percentage of net sales, SG&A expenses were 14.2% and 15.4% for the first nine months of 2022 and 2021, respectively. SG&A expenses for the first nine months of 2022 include merger-related and integration costs of $52.2 million. Adjusted for this amount, SG&A expenses were 13.9% of net sales for the first nine months of 2022. SG&A expenses for the first nine months of 2021 include $119.8 million of merger-related and integration costs, as well as a net gain of $8.9 million resulting from the Canadian divestitures. Adjusted for these amounts, SG&A expenses were 14.6% of net sales for the first nine months of 2021.
SG&A payroll and payroll-related expenses for the first nine months of 2022 of $1.4 billion increased by $80.5 million compared to the same period in 2021 primarily due to higher salaries and variable compensation expense. Additionally, stock-based compensation expense increased as a result of raising our estimate of the payout levels for certain performance-based awards.
SG&A expenses not related to payroll and payroll-related costs for the first nine months of 2022 of $822.6 million increased by $112.7 million compared to the same period in 2021. The increase primarily reflects higher volume-related costs driven by significant sales growth and digital transformation initiatives that contributed to higher expenses in the first nine months of 2022, as well as the absence of the net gain recognized in the first quarter of 2021 on the Canadian divestitures. These increases were partially offset by the realization of integration cost synergies, as well as lower professional and consulting fees associated with integration activities.
Depreciation and Amortization
Depreciation and amortization decreased $9.0 million to $135.6 million for the first nine months of 2022 compared to $144.6 million for the first nine months of 2021. The first nine months of 2022 and 2021 includes $9.4 million and $20.2 million, respectively, resulting from changes in the estimated useful lives of certain legacy trademarks that are migrating to our master brand architecture, as described above.

Income from Operations
The following tables set forth income from operations by segment for the periods presented:

|  | Nine Months Ended September 30, 2022
(In thousands) |  | EES |  | CSS |  | UBS |  | Corporate |  | Total
Income from operations |  | $ | 613,462 |  | $ | 373,789 |  | $ | 471,667 |  | $ | (402,588) |  |  | $ | 1,056,330
|  | Nine Months Ended September 30, 2021
(In thousands) |  | EES |  | CSS |  | UBS |  | Corporate |  | Total
Income from operations |  | $ | 409,062 |  | $ | 293,446 |  | $ | 289,895 |  | $ | (410,814) |  |  | $ | 581,589

Income from operations was $1.1 billion for the first nine months of 2022 compared to $0.6 billion for the first nine months of 2021. The increase of $474.7 million, or 81.6%, reflects sales growth and lower cost of goods sold as a percentage of net sales, along with the realization of integration synergies, partially offset by higher SG&A payroll and payroll-related expenses, volume-related costs, as well as expenses associated with our digital transformation initiatives.
EES reported income from operations of $613.5 million for the first nine months of 2022 compared to $409.1 million for the first nine months of 2021. The increase of $204.4 million primarily reflects the factors impacting the overall business, as described above.
CSS reported income from operations of $373.8 million for the first nine months of 2022 compared to $293.4 million for the first nine months of 2021. The increase of $80.4 million primarily reflects the factors impacting the overall business, as described above. Additionally, operating profit for the first nine months of 2021 was negatively impacted by approximately 40 basis points from the inventory write-down described under Cost of Goods Sold above.
UBS reported income from operations of $471.7 million for the first nine months of 2022 compared to $289.9 million for the first nine months of 2021. The increase of $181.8 million primarily reflects the factors impacting the overall business, as described above, offset by the benefit in the first quarter of 2021 from the net gain on the Canadian divestitures.
Corporate, which primarily incurs costs related to treasury, tax, information technology, legal and other centralized functions, recognized net expenses of $402.6 million for the first nine months of 2022 compared to $410.8 million for the first nine months of 2021. The decrease of $8.2 million primarily reflects a decrease in professional and consulting fees associated with integration activities, partially offset by an increase in information technology expenses.
Other Income and Expense, net
Other non-operating expense totaled $3.0 million for the first nine months of 2022 compared to other non-operating income of $8.9 million for the first nine months of 2021. As disclosed in Note 8, "Employee Benefit Plans" of our Notes to the unaudited Condensed Consolidated Financial Statements, we recognized net benefits of $10.5 million and $12.3 million associated with the non-service cost components of net periodic pension (benefit) cost for the nine months ended September 30, 2022 and 2021, respectively. Due to fluctuations in the U.S. dollar against certain foreign currencies, we recognized a net foreign currency exchange loss of $11.5 million for the first nine months of 2022 compared to a net loss of $1.4 million for the first nine months of 2021.
Income Taxes
The provision for income taxes was $203.2 million for the first nine months of 2022 compared to $84.2 million in last year's comparable period, resulting in effective tax rates of 24.0% and 22.0%, respectively. The effective tax rates for the first nine months of 2022 and last year's comparable period reflect discrete income tax benefits of $13.4 million and $8.3 million, respectively, resulting from reductions to the valuation allowance recorded against foreign tax credit carryforwards, as well as the exercise and vesting of stock-based awards of $9.4 million and $7.8 million, respectively. These discrete income tax benefits were partially offset by discrete income tax expense of $0.8 million and $4.2 million, respectively, resulting from return-to-provision adjustments. The net impact of discrete income tax items was a reduction to the estimated annual effective tax rates in such periods of approximately 2.6 and 3.1 percentage points, respectively.

Net Income and Earnings per Share
Net income for the first nine months of 2022 was $643.0 million compared to $298.6 million for the first nine months of 2021, an increase of $344.4 million, or 115.3%.
Preferred stock dividends expense, which relates to the fixed-rate reset cumulative perpetual preferred stock, Series A, that was issued in connection with the merger with Anixter, was $43.1 million for the first nine months of 2022 and 2021.
Net income and earnings per diluted share attributable to common stockholders were $598.5 million and $11.42, respectively, for the first nine months of 2022 compared to $254.9 million and $4.91, respectively, for the first nine months of 2021. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders were $643.7 million and $12.29, respectively, for the first nine months of 2022. Adjusted for merger-related and integration costs, accelerated trademark amortization, net gain on Canadian divestitures, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders were $353.0 million and $6.80, respectively, for the first nine months of 2021.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
Liquidity and Capital Resources
Our liquidity needs generally arise from fluctuations in our working capital requirements, information technology investments, capital expenditures, acquisitions and debt service obligations. As of September 30, 2022, we had $600.3 million in available borrowing capacity under our Revolving Credit Facility, after giving effect to outstanding letters of credit and certain borrowings under our international lines of credit, which combined with available cash of $84.7 million, provided liquidity of $685.0 million. Cash included in our determination of liquidity represents cash in certain deposit and interest-bearing investment accounts. We monitor the depository institutions that hold our cash and cash equivalents on a regular basis, and we believe that we have placed our deposits with creditworthy financial institutions.
We regularly review our mix of fixed versus variable rate debt, and we may, from time to time, issue or retire borrowings and/or refinance existing debt in an effort to mitigate the impact of interest rate and foreign exchange rate fluctuations, and to maintain a cost-effective capital structure consistent with our anticipated capital requirements. Economic conditions have contributed to increases in interest rates during 2022. Further increases will raise the rates we pay on our variable rate debt and will contribute to higher interest expense versus prior periods.
As of September 30, 2022, approximately 54% of our debt portfolio was comprised of fixed rate debt. We believe our capital structure has an appropriate mix of fixed versus variable rate debt and secured versus unsecured instruments.
Over the next several quarters, it is expected that excess liquidity will be directed primarily at debt reduction, integration activities and potential acquisitions, or returning capital to shareholders through the payment of dividends and our existing share repurchase authorization. We expect to maintain sufficient liquidity through our credit facilities and cash balances. We believe cash provided by operations and financing activities will be adequate to cover our operational and business needs for at least the next twelve months.
We communicate on a regular basis with our lenders regarding our financial and working capital performance, and liquidity position. We were in compliance with all financial covenants and restrictions contained in our debt agreements as of September 30, 2022.
We also measure our ability to meet our debt obligations based on our financial leverage ratio, which was 3.2 as of September 30, 2022 and 3.9 as of December 31, 2021. Since our merger with Anixter on June 22, 2020, we have reduced our financial leverage by 2.5.

(1)Other non-operating income for the twelve months ended September 30, 2022 and December 31, 2021 includes a $36.6 million curtailment gain resulting from the remeasurement of our pension obligations in the U.S. and Canada due to amending certain terms of such defined benefit plans.
(2)Debt is presented in the condensed consolidated balance sheets net of debt discount and debt issuance costs, and includes adjustments to record the long-term debt assumed in the merger with Anixter at its acquisition date fair value.
Note: Financial leverage ratio is a non-GAAP measure of the use of debt. Financial leverage ratio is calculated by dividing total debt, excluding debt discount, debt issuance costs and fair value adjustments, net of cash, by adjusted EBITDA. EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as the trailing twelve months EBITDA before other non-operating expenses (income), non-cash stock-based compensation expense, merger-related and integration costs, and net gain on the divestiture of our legacy utility and data communications businesses in Canada.
Most of the undistributed earnings of our foreign subsidiaries have been taxed in the U.S. under either the one-time tax on the deemed repatriation of undistributed foreign earnings, or the global intangible low-taxed income tax regime imposed by the Tax Cuts and Jobs Act of 2017. Future distributions of previously taxed earnings by our foreign subsidiaries should, therefore, result in minimal U.S. taxation. We continue to assert that the remaining undistributed earnings of our foreign subsidiaries are indefinitely reinvested. The distribution of earnings by our foreign subsidiaries in the form of dividends, or otherwise, may be subject to additional taxation. We believe that we are able to maintain sufficient liquidity for our domestic operations and commitments without repatriating cash from our foreign subsidiaries.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
We finance our operating and investing needs primarily with borrowings under our Revolving Credit Facility, Receivables Facility, as well as uncommitted lines of credit entered into by certain of our foreign subsidiaries to support local operations, some of which are overdraft facilities. The Revolving Credit Facility has a borrowing limit of $1,525 million and the purchase limit under the Receivables Facility is $1,525 million. As of September 30, 2022, we had $883.1 million and $1,525.0 million outstanding under the Revolving Credit Facility and Receivables Facility, respectively. The maximum borrowing limits of our international lines of credit vary by facility and range between $0.6 million and $31.0 million. Our international lines of credit generally are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by Wesco Distribution. Accordingly, certain borrowings under these lines directly reduce availability under our Revolving Credit Facility. As of September 30, 2022, we had $6.7 million outstanding under our international lines of credit.
On March 1, 2022, we amended our Receivables Facility to increase its borrowing capacity from $1,300 million to $1,400 million and extend its maturity date from June 21, 2024 to March 1, 2025. Additionally, the amendments to the Receivables Facility replaced the LIBOR-based interest rate option with SOFR-based interest rate options, including term SOFR and daily simple SOFR, and decreased the interest rate spread from 1.15% to 1.10%.
On March 1, 2022, we also amended our Revolving Credit Facility to, among other things, increase its borrowing capacity from $1,200 million to $1,350 million, extend its maturity date from June 22, 2025 to March 1, 2027, and replace its LIBOR-based interest rate option with SOFR-based interest rate options, including term SOFR and daily simple SOFR.
On August 2, 2022, we further amended our Receivables Facility to increase its borrowing capacity from $1,400 million to $1,525 million and to decrease the interest rate spread from 1.10% to 1.05%.

Contractual Cash Obligations and Other Commercial Commitments

Seasonality
Our operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters are usually affected by a reduced level of activity due to the impact of weather on projects. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction, our sales by quarter have varied significantly from this pattern.
Critical Accounting Estimates
There have been no significant changes to the critical accounting estimates disclosed in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of WESCO International, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Recent Accounting Standards
See Note 2, "Accounting Policies" of our Notes to the unaudited Condensed Consolidated Financial Statements for a description of recently adopted and recently issued accounting standards.
Forward-Looking Statements
All statements made herein that are not historical facts should be considered as forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements involve known and unknown risks, uncertainties and other factors that may cause actual results to differ materially. These statements include, but are not limited to, statements relating to plans to declare and pay dividends, statements regarding the expected benefits and costs of the transaction between Wesco and Anixter, including anticipated future financial and operating results, synergies, accretion and growth rates, and the combined company's plans, objectives, expectations and intentions, statements that address the combined company's expected future business and financial performance, and other statements identified by words such as "anticipate," "plan," "believe," "estimate," "intend," "expect," "project," "will" and similar words, phrases or expressions. These forward-looking statements are based on current expectations and beliefs of Wesco's management, as well as assumptions made by, and information currently available to, Wesco's management, current market trends and market conditions and involve risks and uncertainties, many of which are outside of Wesco's and Wesco's management's control, and which may cause actual results to differ materially from those contained in forward-looking statements. Accordingly, you should not place undue reliance on such statements.
Those risks, uncertainties and assumptions include the risk of any unexpected costs or expenses resulting from the transaction, the risk that the transaction could have an adverse effect on the ability of the combined company to retain customers and retain and hire key personnel and maintain relationships with its suppliers, customers and other business relationships and on its operating results and business generally, or the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or other anticipated benefits of the transaction or it may take longer than expected to achieve those synergies or benefits, the risk that the leverage of the company may be higher than anticipated, the impact of natural disasters (including as a result of climate change), health epidemics, pandemics and other outbreaks, such as the ongoing COVID-19 pandemic, supply chain disruptions, and the impact of Russia's invasion of Ukraine, including the impact of sanctions or other actions taken by the U.S. or other countries, the increased risk of cyber incidents and exacerbation of key materials shortages, inflationary cost pressures, material cost increases, demand volatility, and logistics and capacity constraints, which may have a material adverse effect on the combined company's business, results of operations and financial condition, and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond the combined company's control. Additional factors that could cause results to differ materially from those described above can be found in WESCO International, Inc.'s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and WESCO International, Inc.'s other reports filed with the SEC.
Item 3. Quantitative and Qualitative Disclosures about Market Risks.
For a discussion of changes to the market risks that were previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, refer to Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations” and to Part II, Item 1A, "Risk Factors”.
Item 4. Controls and Procedures.
Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures and internal control over financial reporting were effective as of the end of the period covered by this report.
There were no changes in the Company’s internal control over financial reporting that occurred during the quarterly period ended September 30, 2022, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION
Item 1. Legal Proceedings.
As set forth in Note 10, "Commitments and Contingencies" to the Notes to the unaudited Condensed Consolidated Financial Statements, from time to time, a number of lawsuits and claims have been or may be asserted against us relating to the conduct of our business, including litigation relating to commercial, product and employment matters (including wage and hour). The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to us. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on our financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on our results of operations for that period.
Item 1A. Risk Factors.
Various of the risk factors previously disclosed in Item 1A. to Part I of WESCO International, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 address matters such as political instability, armed conflict, trade sanctions, cybersecurity, economic and financial market instability, supply chain challenges, commodity pricing and inflationary pressures. Russia’s invasion of Ukraine in the first quarter of 2022, the ongoing conflict, and the resulting international response have heightened such risks. While Wesco’s business and operations have not been materially adversely affected thus far, the situation remains unstable and uncertain, and we are unable to predict the possible effects on us should the conflict escalate or be further prolonged.
