WESCO INTERNATIONAL INC (WCC) FY 2023 MD&A

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the audited consolidated financial statements and notes thereto included in Item 8 of this Annual Report on Form 10-K. 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 this Annual Report on Form 10-K. In this Item 7, “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 other non-operating expense (income), 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 helpful to users of our financial statements 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 users to more easily compare our financial performance from period to period. Management uses certain non-GAAP financial measures in its evaluation of the performance of the Company's operating segments and in the determination of incentive compensation. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated above.

In the first quarter of the fiscal year ended December 31, 2023, we changed our presentation in tables from thousands to millions. Certain amounts as of and for the year ended December 31, 2022 in Management’s Discussion and Analysis of Financial Condition and Results of Operations may not foot or recalculate due to rounding.

Company Overview

Wesco, headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.

We employ approximately 20,000 people, maintain relationships with more than 50,000 suppliers, and serve nearly 150,000 customers worldwide. With millions of products, end-to-end supply chain services, and leading digital capabilities, we provide innovative solutions to meet customer needs across commercial and industrial businesses, contractors, government agencies, educational 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 operate nearly 800 branches, warehouses and sales offices in approximately 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and global 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. In 2022, we launched the master brand identity in North America and began migrating certain legacy sub-brands to the master brand architecture, a process that will continue for the next several years. In 2023, we launched the Wesco Anixter go-to-market brand in all markets outside of the U.S. and Canada, as part of our master brand deployment strategy. Due to the strength of its recognition with customers and suppliers, we will continue to use the Anixter brand name globally 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. See Item 1, “Business” in this Annual Report on Form 10-K for a description of each of our reportable segments and their business activities.

Overall Financial Performance

Our financial results for 2023 compared to 2022 reflect single-digit sales growth driven by the benefits of price inflation, increased scale, and secular demand trends. These impacts were partially offset by volume declines in certain businesses, as well as slight margin contraction, and higher payroll and payroll-related expenses, costs to operate our facilities, along with expenses associated with our digital transformation initiatives.

Net sales for 2023 increased $965.1 million, or 4.5%, over the prior year. The increase reflects the estimated impact of changes in price of approximately 3% and the favorable impact of 2.1% from the acquisition of Rahi Systems Holdings, Inc. (“Rahi Systems”), which closed in November of 2022. These positive factors were partially offset by the negative impacts of

fluctuations in foreign exchange rates of 0.4% and the number of workdays of 0.4%. Volume growth did not have a material impact on the year-over-year increase in organic sales. Cost of goods sold as a percentage of net sales was 78.4% and 78.2% for 2023 and 2022, respectively. The unfavorable increase of 20 basis points reflects lower supplier volume rebates and a shift in sales mix, partially offset by our continued focus on a strategy of pricing products and services to realize the value that we provide to our customers as a result of our broad portfolio of product and service offerings, global footprint and capabilities (“value-driven pricing”).

Income from operations was $1,406.4 million for 2023, compared to $1,438.1 million for 2022, a decrease of $31.7 million, or 2.2%. Income from operations as a percentage of net sales was 6.3% for the current year, compared to 6.7% for the prior year. Income from operations for 2023 includes merger-related and integration costs of $55.4 million, restructuring costs of $16.7 million, and accelerated trademark amortization expense of $1.6 million. Adjusted for these items, income from operations was 6.6% of net sales in 2023. For 2022, income from operations was 7.1% of net sales, as adjusted for merger-related and integration costs of $67.4 million and accelerated trademark amortization expense of $9.8 million. For 2023, income from operations declined compared to the prior year due to higher cost of goods sold as a percentage of net sales, higher salaries and benefits due to wage inflation and increased headcount, including the impact of the Rahi Systems acquisition, as well as an increase in volume-related costs such as commissions and marketing costs. The costs to operate our facilities also unfavorably affected income from operations. In addition, digital transformation initiatives contributed to higher expenses in 2023. These negative factors were partially offset by sales growth as well as the realization of integration synergies and a reduction to incentive compensation expense.

Earnings per diluted share for 2023 was $13.54, based on 52.3 million diluted shares, compared to $15.33 for 2022, based on 52.4 million diluted shares, a decrease of 11.7%. Adjusted for merger-related and integration costs, restructuring costs, accelerated trademark amortization expense, net pension settlement cost, and the related income tax effects, earnings per diluted share for 2023 was $14.60. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, earnings per diluted share for 2022 was $16.42. Adjusted earnings per diluted share decreased 11.1% year-over-year.

Our industry and the broader economy have experienced supply chain challenges, including product delays and backlogged orders, shortages in raw materials and components, labor shortages, transportation challenges, and higher costs. We have aggressively responded to these supply chain issues which have largely improved and progressively become manageable throughout 2023.

Cash Flow

Operating cash flow for 2023 was $493.2 million. Net cash provided by operating activities included net income of $766.1 million and non-cash adjustments to net income totaling $235.8 million, which primarily consisted of depreciation and amortization of $181.3 million, stock-based compensation expense of $48.1 million, amortization of debt discount and debt issuance costs of $14.8 million, and deferred income taxes of $7.9 million. Operating cash flow was negatively impacted by net changes in assets and liabilities of $508.7 million, which primarily consisted of a decrease in accounts payable of $319.7 million, mainly due to a reduction in inventory purchases in the fourth quarter, and an increase in inventories of $68.4 million. Inventories grew at a slower rate than sales, as supply chain lead times have normalized. These cash usage factors were partially offset by cash inflow from a decrease in trade accounts receivable of $52.2 million. Additionally, the payment of management incentive compensation earned in 2022 resulted in a cash outflow of approximately $153.9 million in 2023, which was partially offset by the accrual of management incentive compensation earned in the current year.

Investing activities primarily included $92.3 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 primarily consisted of net repayments of $70.3 million related to our revolving credit facility (the “Revolving Credit Facility”) and the repayment of our $58.6 million aggregate principal amount of 5.50% Anixter Senior Notes due 2023, which matured on March 1, 2023, partially offset by net borrowings of $15.0 million related to our accounts receivable securitization facility (the “Receivables Facility”). Financing activities for 2023 also included $76.6 million and $57.4 million of dividends paid to holders of our common stock and Series A Preferred Stock, respectively, $75.0 million of common stock repurchases, and $68.3 million of payments for taxes related to the exercise and vesting of stock-based awards.

Financing Availability

As of December 31, 2023, we had $736.0 million in total available borrowing capacity under our Revolving Credit Facility and $75.0 million of available borrowing capacity under our Receivables Facility. The Revolving Credit Facility and the Receivables Facility mature in March 2027 and March 2025, respectively. As of December 31, 2023, we also had $8.2 million of borrowing capacity available under our international lines of credit that did not directly reduce availability under the Revolving Credit Facility.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations, including those related to goodwill and indefinite-lived intangible assets, defined benefit pension plans, and income taxes. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. If actual market conditions are less favorable than those projected by management, additional adjustments to reserve items may be required. We believe the following accounting estimates are the most critical to the understanding of our consolidated financial statements as they require subjective or complex judgments by management.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill and indefinite-lived intangible assets are tested for impairment annually as of October 1, or more frequently if triggering events occur, indicating that their carrying values may not be recoverable. We test for goodwill impairment on a reporting unit level. We performed our annual impairment tests of goodwill and indefinite-lived intangible assets during the fourth quarter of 2023 by assessing qualitative factors to determine whether it was more likely than not that the fair values of our reporting units and indefinite-lived intangible assets were less than their respective carrying amounts. As a result of this assessment, we determined that it was more likely than not that the fair values of our reporting units and indefinite-lived intangible assets continued to exceed their respective carrying amounts and, therefore, a quantitative impairment test was not necessary.

The determination of fair value involves significant management judgment, particularly as it relates to the underlying assumptions and factors around future expected operating margins and discount rate. Management applies its best judgment when assessing the reasonableness of financial projections. Fair values are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill and indefinite-lived intangible impairment tests will prove to be an accurate prediction of future results.

See Note 2, “Accounting Policies” and Note 5, “Goodwill and Intangible Assets” of our Notes to Consolidated Financial Statements for additional disclosure regarding goodwill and indefinite-lived intangible assets.

Defined Benefit Pension Plans

Liabilities and expenses for defined benefit pension plans are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated cash flows, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (salary increases, retirement age, and mortality).

Liabilities for defined benefit pension plans are particularly sensitive to changes in the discount rate. At the end of each fiscal year, we determine the discount rate to measure our defined benefit pension plan liabilities at their present value. The discount rate reflects the current rate at which the defined benefit pension plan liabilities could be effectively settled at the end of the year. This rate is estimated using a yield curve based on corporate bond data, which we believe is consistent with observable market conditions and industry standards for developing spot rate curves. The consolidated weighted-average discount rate used to measure the projected benefit obligation of all plans was 4.4% and 4.6% at December 31, 2023 and 2022, respectively. As a sensitivity measure, the effect of a 50-basis-point decline in the assumed discount rate would result in no change in the expense for 2024, and an increase in our projected benefit obligations at December 31, 2023 of $31.0 million. The impact of a 50-basis-point increase in the assumed discount rate would result in a decrease in the expense for 2024 of approximately $1.0 million, and a decrease in our projected benefit obligations at December 31, 2023 of $29.0 million. Changes in the expected long-term rate of return on plan assets and assumptions relating to the employee workforce are less likely to have a material impact on the measurement of defined benefit pension plan liabilities.

See Note 2, “Accounting Policies” and Note 13, “Employee Benefit Plans” of our Notes to Consolidated Financial Statements for additional disclosure regarding defined benefit pension plans.

Income Taxes

We recognize deferred tax assets consistent with amounts expected to be realized. To make such determination, management evaluates all positive and negative evidence, including but not limited to, prior, current and future taxable income, tax planning strategies and future reversals of existing taxable temporary differences. A valuation allowance is recognized if it is “more-likely-than-not” that some or all of a deferred tax asset will not be realized. We regularly assess the realizability of deferred tax assets.

We account for uncertainty in income taxes using a “more-likely-than-not” recognition threshold. Due to the subjectivity inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ from the estimate recognized in the consolidated financial statements. We recognize interest and penalties related to uncertain tax benefits as part of interest expense and income tax expense, respectively.

See Note 2, “Accounting Policies” and Note 11, “Income Taxes” of our Notes to Consolidated Financial Statements for additional disclosure regarding income taxes.

Results of Operations

2023 Compared to 2022

Net Sales

The following table sets forth net sales and organic sales growth for the periods presented:

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. Workday impact represents the change in the number of operating days period-over-period after adjusting for weekends and public holidays in the United States; 2023 had one less workday compared to 2022.

Net sales were $22.4 billion for 2023 compared with $21.4 billion for 2022, an increase of 4.5%. Adjusting for the favorable impact from the acquisition of Rahi Systems of 2.1%, the unfavorable impacts from fluctuations in foreign exchange rates of 0.4% and the number of workdays of 0.4%, organic sales for 2023 grew by 3.2%. The increase was primarily due to the impact of changes in price, which favorably impacted organic sales by approximately 3%. Volume growth did not have a material impact on the year-over-year increase in organic sales, as increases in sales volume in the CSS and UBS operating segments were offset by a decrease in sales volume in the EES segment.

Cost of Goods Sold

Cost of goods sold for 2023 was $17.5 billion compared to $16.8 billion for 2022. Cost of goods sold as a percentage of net sales was 78.4% and 78.2% for 2023 and 2022, respectively. The unfavorable increase of 20 basis points reflects a shift in sales mix and lower supplier volume rebates, partially offset by our continued focus on a strategy of pricing products and services to realize the value that we provide to our customers as a result of our broad portfolio of product and service offerings, global footprint and capabilities (“value-driven pricing”).

Selling, General and Administrative Expenses

Selling, general and administrative (“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 2023 totaled $3.3 billion versus $3.0 billion for 2022, an increase of 7.0%. As a percentage of net sales, SG&A expenses were 14.5% and 14.2% for 2023 and 2022, respectively. SG&A expenses for 2023 and 2022 include merger-related and integration costs of $55.4 million and $67.4 million, respectively. SG&A expenses for 2023 also include $16.7 million of restructuring costs. Adjusted for merger-related and integration costs, and restructuring costs, SG&A expenses for 2023 were 14.2% of net sales for 2023 and 13.9% of net sales for 2022.

28

Table of Contents

SG&A payroll and payroll-related expenses for 2023 of $2.1 billion increased by $89.4 million compared to 2022 as a result of higher salaries and benefits due to wage inflation and increased headcount, including the impact of the Rahi Systems acquisition, partially offset by the impact of headcount reductions taken at the end of the second quarter of 2023. This increase in payroll and payroll-related expenses also includes an increase in sales commissions of $31.9 million and a reduction to incentive compensation expense of $98.3 million.

SG&A expenses not related to payroll and payroll-related costs for 2023 were $1.2 billion, an increase of $122.4 million compared to 2022, which primarily reflects higher costs to operate our facilities of $49.2 million, increased marketing costs of $11.5 million, as well as higher employee expenses of $6.6 million due to increased headcount. In addition, digital transformation initiatives contributed to higher expenses of $22.4 million in 2023, which includes higher professional and consulting expenses. These increases were partially offset by the realization of integration cost synergies.

Depreciation and Amortization

Depreciation and amortization increased $2.3 million to $181.3 million for 2023, compared to $179.0 million for 2022. Depreciation and amortization for 2023 and 2022 includes $1.6 million and $9.8 million, respectively, of accelerated amortization expense resulting from changes in the estimated useful lives of certain legacy trademarks that are migrating to our master brand architecture.

Income from Operations

Income from operations was $1,406.4 million for 2023 compared to $1,438.1 million for 2022. The decrease of $31.7 million, or 2.2%, reflects slightly higher cost of goods sold as a percentage of net sales and higher SG&A expenses, as described above, partially offset by sales growth and the realization of integration synergies.

Interest Expense, net

Net interest expense totaled $389.3 million for 2023 compared to $294.4 million for 2022. The increase of $94.9 million, or 32.2%, reflects higher borrowings and an increase in variable interest rates.

Other Expense, net

Other non-operating expense totaled $25.1 million for 2023 compared to $7.0 million for 2022. Due to fluctuations in the U.S. dollar against certain foreign currencies, particularly the Argentine Peso and the Egyptian Pound, a net foreign currency exchange loss of $22.9 million was recognized for 2023 compared to a net loss of $19.9 million for 2022. We recognized net costs of $0.2 million and net benefits of $14.8 million associated with the non-service cost components of net periodic pension cost (benefit) for 2023 and 2022, respectively. The year-over-year change was primarily due to a decrease in expected return on plan assets and an increase in interest cost. Other non-operating expense for 2023 includes net pension settlement cost of $2.8 million primarily related to the partial settlement of the Company's pension plan in the U.S., partially offset by pension settlement gains related to other plans. Adjusted for this amount, other non-operating expense was $22.3 million for 2023.

Income Taxes

The provision for income taxes was $225.9 million for 2023 compared to $274.5 million for 2022, resulting in effective tax rates of 22.8% and 24.2%, respectively. The effective tax rate for both the current year and the prior year were favorably impacted by the tax benefits related to the exercise and vesting of stock-based awards and reductions in the valuation allowance recorded against certain deferred tax assets. The lower effective tax rate in the current year is due primarily to higher tax benefits from stock-based compensation deductions and foreign tax credit utilization as compared to the prior year.

Net Income and Earnings per Share

Net income and earnings per diluted share attributable to common stockholders were $708.1 million and $13.54, respectively, for 2023 compared to $803.1 million and $15.33, respectively, for 2022. Adjusted for merger-related and integration costs, restructuring costs, accelerated trademark amortization expense, net pension settlement cost, and the related income tax effects, net income and earnings per diluted share attributable to common stockholders were $763.6 million and $14.60, respectively, for the year ended December 31, 2023. 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 $860.1 million and $16.42, respectively, for the year ended December 31, 2022.

Adjusted EBITDA

Adjusted EBITDA, a non-GAAP financial measure, was $1,705.3 million for 2023 compared to $1,725.6 million for 2022. Adjusted EBITDA decreased $20.3 million, or 1.2% year-over-year. The decrease primarily reflects the $211.8 million increase in SG&A expenses, as well as the increase in cost of goods sold of $782.7 million, partially offset by the $1.0 billion increase in net sales, as described above. Included in the increase in SG&A expenses was restructuring costs of $16.7 million, partially offset by a decrease in merger-related and integration costs of $12.0 million.

Segment Results

The following is a discussion of the financial results of our operating segments comprising three strategic business units consisting of EES, CSS and UBS for the year ended December 31, 2023. As further described below and in Note 16, “Business Segments” of our Notes to the Consolidated Financial Statements, the performance of our operating segments is based on net sales, adjusted EBITDA, and adjusted EBITDA margin percentage. Adjusted EBITDA and adjusted EBITDA margin percentage are non-GAAP financial measures.

Electrical & Electronic Solutions

EES reported net sales of $8.6 billion for 2023 compared to $8.8 billion for 2022, a decrease of 2.4%. Adjusting for the unfavorable impact from fluctuations in foreign exchange rates of 0.6% and the number of workdays of 0.4%, EES organic sales for 2023 declined 1.4%, reflecting volume declines of approximately 2%, primarily as a result of declines in construction and original equipment manufacturers, partially offset by continued positive momentum in industrial and the benefits of selling the broader company portfolio (“cross selling”). In addition, a transfer of certain customer accounts to the CSS segment negatively impacted organic net sales for EES by approximately 2%. These negative factors were partially offset by the impact of changes in price, which favorably impacted organic sales by approximately 3%.

EES reported adjusted EBITDA of $727.4 million for 2023, or 8.4% of net sales, compared to $851.3 million for 2022, or 9.6% of net sales. Adjusted EBITDA decreased $123.9 million, or 14.6% year-over-year. The decrease primarily reflects the decline in net sales, as described above, and an increase in SG&A expenses as a percentage of net sales, partially offset by a decrease in cost of goods sold of $131.8 million, which is inclusive of higher inventory write-downs and lower supplier volume rebates totaling approximately $28.7 million and the negative impact of a shift in sales mix. SG&A expenses increased $41.6 million as compared to the prior year, which was primarily attributed to higher payroll and payroll-related expenses of $43.6 million as a result of higher salaries due to wage inflation and increased headcount. This increase in payroll and payroll-related expenses also includes a reduction to incentive compensation expense of $31.4 million.

Communications & Security Solutions

CSS reported net sales of $7.2 billion for 2023 compared to $6.4 billion for 2022, an increase of 11.7%. Adjusting for the favorable impact from the acquisition of Rahi Systems of 7.1%, the unfavorable impacts from fluctuations in foreign exchange rates of 0.4% and the number of workdays of 0.4%, CSS organic sales for 2023 grew 5.4%, reflecting the impact of changes in price, which favorably impacted organic sales by approximately 1%. Volume growth, which includes growth in data center, security solutions and enterprise network infrastructure and the benefits of cross selling, favorably impacted organic sales by approximately 1%. The transfer of certain customer accounts from the EES segment also positively impacted organic net sales for CSS by approximately 3%.

CSS reported adjusted EBITDA of $683.8 million for 2023, or 9.6% of net sales, compared to $599.0 million for 2022, or 9.4% of net sales. Adjusted EBITDA increased $84.8 million, or 14.2% year-over-year. The increase primarily reflects the increase in net sales, as described above, partially offset by a corresponding increase in cost of goods sold of $580.2 million. SG&A expenses increased $90.5 million as compared to the prior year, which was primarily attributed to higher payroll and payroll-related expenses of $45.1 million as a result of higher salaries due to wage inflation and increased headcount, including the impact of the Rahi Systems acquisition. This increase in payroll and payroll-related expenses also includes an increase in sales commissions of $26.1 million and a reduction to incentive compensation expense of $29.9 million. Additionally, higher costs to operate our facilities of $15.9 million, higher marketing costs of $6.8 million due to increased sales volume, and higher employee expenses of $5.9 million due to increased headcount contributed to the year-over-year increase in SG&A expenses.

Utility & Broadband Solutions

UBS reported net sales of $6.6 billion for 2023 compared to $6.2 billion for 2022, an increase of 6.9%. Adjusting for the unfavorable impacts of fluctuations in foreign exchange rates of 0.2% and the number of workdays of 0.4%, UBS organic sales for 2023 grew 7.5%, reflecting the impact of changes in price, which favorably impacted organic sales by approximately 6%. Volume growth, which includes growth in utility and integrated supply, and the benefits of cross selling, partially offset by lower sales in broadband, particularly in Canada, favorably impacted organic sales by approximately 2%.

UBS reported adjusted EBITDA of $739.3 million for 2023, or 11.2% of net sales, compared to $677.3 million for 2022, or 10.9% of net sales. Adjusted EBITDA increased $62.0 million, or 9.2% year-over-year. The increase primarily reflects the $427.4 million increase in net sales, as described above, partially offset by a corresponding increase in cost of goods sold of $334.4 million. SG&A expenses increased $31.2 million as compared to the prior year, which was primarily attributed to higher payroll and payroll-related expenses of $13.2 million as a result of higher salaries due to wage inflation and increased headcount. This increase in payroll and payroll-related expenses includes a reduction to incentive compensation expense of $6.5 million and a decrease in sales commissions of $1.1 million. Additionally, higher costs to operate our facilities of $13.9 million and increased transportation costs of $4.1 million as a result of sales growth, contributed to the year-over-year increase in SG&A expenses.

Note: For the year ended December 31, 2023, SG&A expenses, income from operations, other non-operating expense, the provision for income taxes and earnings per diluted share have been adjusted to exclude merger-related and integration costs, restructuring costs, accelerated amortization expense associated with migrating to our master brand architecture, net pension settlement cost primarily related to the partial settlement of the Company's pension plan in the U.S., partially offset by pension settlement gains related to other plans, and the related income tax effects. For the year ended December 31, 2022, SG&A expenses, income from operations, the provision for income taxes and earnings per diluted share have been adjusted to exclude merger-related and integration costs, accelerated trademark amortization expense associated with migrating to our master brand architecture, and the related income tax effects. These non-GAAP financial measures provide a better understanding of our financial results on a comparable basis.

Liquidity and Capital Resources

Our liquidity needs generally arise from fluctuations in our working capital requirements, information technology investments, capital expenditures, acquisitions, the payment of dividends, and debt service obligations. As of December 31, 2023, we had $736.0 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, and $75.0 million in available borrowing capacity under our Receivables Facility, which combined with available cash of $250.1 million, provided liquidity of $1.1 billion. 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 contributed to increases in interest rates during 2023 and 2022. Further increases will raise the rates we pay on our variable rate debt and will contribute to higher interest expense versus prior periods.

At December 31, 2023, approximately 53% of our debt portfolio consisted 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, we expect that our excess liquidity will be directed primarily at debt reduction, digital transformation initiatives, returning capital to shareholders through the payment of dividends and our existing share repurchase authorization, or potential acquisitions and related integration activities. 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 December 31, 2023.

We also measure our ability to meet our debt obligations based on our financial leverage ratio, which was 2.8x as of December 31, 2023 and 2.9x as of December 31, 2022.

The following table sets forth our financial leverage ratio, which is a non-GAAP financial measure, for the periods presented:

(1)    Merger-related and integration costs include integration and professional fees associated with the integration of Wesco and Anixter, including digital transformation costs, as well as advisory, legal, and separation costs associated with the merger between the two companies.

(2)    Restructuring costs include severance costs incurred pursuant to an ongoing restructuring plan.

(3)    Debt is presented in the 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 expense (income), non-cash stock-based compensation expense, merger-related and integration costs, and restructuring costs.

The undistributed earnings of our foreign subsidiaries amounted to approximately $2,194.1 million at December 31, 2023. Most of these earnings have been taxed in the U.S. under either the one-time tax on the deemed repatriation of undistributed foreign earnings (the “transition tax”), or the global intangible low-taxed income (“GILTI”) tax regime imposed by the Tax Cuts and Jobs Act of 2017. We have elected to pay the transition tax in installments over an eight year period, which ends in 2026. As of December 31, 2023, our remaining liability for the transition tax was $53.8 million. 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 estimate that additional taxes of approximately $119.3 million would be payable upon the remittance of all previously undistributed foreign earnings as of December 31, 2023, based upon the laws in effect on that date. We believe that we are able to maintain sufficient liquidity for our domestic operations and commitments without repatriating cash from our foreign subsidiaries.

We finance our operating and investing needs primarily with borrowings under our Revolving Credit Facility and 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 $1,725 million and the purchase limit under the Receivables Facility is $1,625 million. As of December 31, 2023, we had $953.0 million and $1,550.0 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 $10.0 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 December 31, 2023, there was $8.2 million of borrowing capacity available under the international lines of credit that did not directly reduce availability under the Revolving Credit Facility. As of December 31, 2023, we had $1.0 million outstanding under our international lines of credit.

On March 1, 2023, we repaid the $58.6 million aggregate principal amount of our 5.50% Anixter Senior Notes due 2023. The repayment was funded with borrowings under our Revolving Credit Facility and had no impact on our results of operations.

Our $1,500 million of 7.125% Senior Notes will mature on June 15, 2025 (“2025 Notes”). On and after June 15, 2024, all or part of the 2025 Notes may be redeemed at a redemption price equal to 100% of the principal amount. We expect to complete a transaction or transactions to refinance the 2025 Notes during 2024.

For information regarding amendments to the Receivables Facility and Revolving Credit Facility as well as disclosure of our debt instruments, including our outstanding indebtedness as of December 31, 2023, see Note 9, “Debt” of our Notes to Consolidated Financial Statements.

An analysis of cash flows for 2023 and 2022 follows:

Operating Activities

Net cash provided by operating activities for 2023 totaled $493.2 million, compared to $11.0 million of cash generated in 2022. Net cash provided by operating activities for 2023 included net income of $766.1 million and non-cash adjustments to net income totaling $235.8 million, which primarily consisted of depreciation and amortization of $181.3 million, stock-based compensation expense of $48.1 million, and amortization of debt discount and debt issuance costs of $14.8 million, partially offset by deferred income taxes of $7.9 million.

Other sources of cash in 2023 included a decrease in trade accounts receivable of $52.2 million due to the timing of receipts from customers and a decrease in net sales in the fourth quarter of 2023 compared to the fourth quarter of the prior year and a decrease in other accounts receivable of $3.6 million due primarily to the collection of supplier volume rebates earned in 2022 in excess of income accrued during the current period, partially offset by an increase in value-added tax receivables. Primary uses of cash in 2023 included a decrease in accounts payable of $319.7 million primarily due to a reduction in inventory purchases in the fourth quarter, a decrease in accrued payroll and benefit costs of $92.3 million resulting primarily from the payment of management incentive compensation earned in 2022, partially offset by the accrual of management incentive compensation earned in the current year. Net operating cash flow was also negatively impacted by $68.4 million from an increase in inventories. Inventories grew at a slower rate than sales, as supply chain lead times have normalized. Uses of cash in 2023 also included an increase in other current and noncurrent assets of $60.6 million primarily due to an increase in capitalized costs associated with developing cloud computing arrangements to support our digital transformation initiatives, as well as a decrease in other current and noncurrent liabilities of $23.5 million.

Net cash provided by operating activities for 2022 totaled $11.0 million. Net cash provided by operating activities for 2022 included net income of $862.1 million and non-cash adjustments to net income totaling $243.1 million, which primarily consisted of depreciation and amortization of $179.0 million, stock-based compensation expense of $46.4 million, and amortization of debt discount and debt issuance costs of $15.2 million, partially offset by deferred income taxes of $1.2 million.

Other sources of cash in 2022 included an increase in accounts payable of $552.9 million due to higher purchases of inventory and an increase in other current and noncurrent liabilities of $131.6 million, primarily due to increases in deferred revenue and accrued taxes. Primary uses of cash in 2022 included an increase in inventories of $817.0 million due to supply chain challenges and to support growth in our sales backlog, including project-based business, an increase in trade accounts receivable of $690.6 million resulting from significant sales growth, an increase in other current and noncurrent assets of $153.2 million, primarily due to an increase in capitalized costs associated with developing cloud computing arrangements to support our digital transformation initiatives, an increase in other receivables of $54.8 million associated with higher supplier volume rebate income accruals, and a decrease in accrued payroll and benefit costs of $63.1 million due to lower incentive compensation accruals.

Investing Activities

Net cash used in investing activities in 2023 was $89.6 million, compared to $283.6 million in 2022. Included in 2023 were capital expenditures of $92.3 million which primarily consisted 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.

Net cash used in investing activities in 2022 was $283.6 million. Included in 2022 was $255.4 million of cash paid to acquire Rahi Systems, less cash acquired of $68.6 million, as described in Note 6, “Acquisitions and Disposals” of our Notes to Consolidated Financial Statements. Capital expenditures were $99.4 million in 2022.

Financing Activities

Net cash used in financing activities in 2023 was $403.9 million, compared to $584.0 million of net cash provided by financing activities in 2022. During 2023, financing activities primarily consisted of net repayments of $70.3 million related to our Revolving Credit Facility and the repayment of our $58.6 million aggregate principal amount of 5.50% Anixter Senior Notes due 2023, partially offset by net borrowings of $15.0 million related to our Receivables Facility. Financing activities for 2023 also included $76.6 million and $57.4 million of dividends paid to holders of our common stock and Series A Preferred Stock, respectively, $75.0 million of common stock repurchases, $68.3 million of payments for taxes related to the exercise and vesting of stock-based awards, and net repayments on our various international lines of credit of approximately $6.0 million.

Net cash provided by financing activities in 2022 was $584.0 million. During 2022, financing activities primarily consisted of net borrowings of $433.0 million related to our Revolving Credit Facility and net borrowings of $265.0 million related to our Receivables Facility. Financing activities for 2022 also included $57.4 million of dividends paid to holders of our Series A Preferred Stock, $25.8 million of payments for taxes related to the exercise and vesting of stock-based awards, borrowings and repayments of $19.5 million and $19.5 million, respectively, related to our various international lines of credit, and $11.1 million of common stock repurchases.

The following table summarizes our material cash requirements from known contractual and other obligations at December 31, 2023, including interest, and the expected effect on our liquidity and cash flow in future periods:

(1)    Interest on variable rate debt was calculated using the rates and balances outstanding at December 31, 2023.

(2)    As disclosed in Note 13, “Employee Benefit Plans” of our Notes to Consolidated Financial Statements, the majority of our various 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 the plans. Our policy is to fund these plans as required by the Employee Retirement Income Security Act, the Internal Revenue Service and local statutory law. We currently estimate that we will contribute $7.0 million to our foreign pension plans in 2024. Due to the future impact of various market conditions, rates of return and changes in plan participants, we cannot provide a meaningful estimate of our future contributions beyond 2024.

In addition to the cash requirements disclosed in the table above, we expect future uses of cash to include working capital requirements, capital expenditures, investments in our digital capabilities, dividend payments to holders of our common stock and Series A Preferred Stock, benefit payments to participants in our deferred compensation plan, and other organic opportunities. Future uses of cash could also include acquisitions of businesses and the repurchase of common or preferred stock. We expect to spend approximately $100 million in 2024 on capital expenditures for information technology investments and to support our global network of branches, warehouses and sales offices.

We expect to fund future uses of cash with a combination of existing cash balances, cash generated from operating activities, borrowings under our revolving credit and accounts receivable securitization facilities, or new issuances of debt.

Purchase orders for inventory requirements and service contracts are not included in the table above. Generally, our purchase orders and contracts contain clauses allowing for cancellation. We do not have significant agreements to purchase material or goods that would specify minimum order quantities.

Table of Contents

Liabilities related to unrecognized tax benefits, including interest and penalties, of $133.7 million were excluded from the table above as we cannot reasonably estimate the timing of these potential cash settlements with taxing authorities. See Note 11, “Income Taxes” in our Notes to Consolidated Financial Statements for further information related to unrecognized tax benefits.

Seasonality

Our operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters have historically been 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.
