WestRock Reports First Quarter Fiscal 2024 Results

ATLANTA--(BUSINESS WIRE)--February 1, 2024--WestRock Company (NYSE:WRK), a leading provider of sustainable paper and packaging solutions, today announced results for its fiscal first quarter ended December 31, 2023.

First Quarter Highlights and other notable items:

Net sales of $4.6 billion; Corrugated Packaging segment sales increased 3.5% compared to the prior year quarter
Global Paper containerboard shipments increased 21.9% compared to the prior year quarter
Net loss of $22 million, Adjusted Net Income of $51 million; net loss included $66 million of restructuring and other costs, net
Loss of $0.09 per diluted share (“EPS”) and earned $0.20 of Adjusted EPS
Consolidated Adjusted EBITDA of $571 million
Consumer Packaging Adjusted EBITDA margin increased 60 bps to 15.7%
Achieved over $200 million in cost savings; expect to significantly exceed previously announced fiscal 2024 target of $300 to $400 million

“During the quarter, we grew external containerboard shipments, while we felt the impact of lower paperboard market demand,” said David B. Sewell, chief executive officer. “We continue to expect significantly improved demand in the second half of our fiscal year.

“We are continuing to deliver on, and we expect to significantly exceed, our cost savings targets. Our transformation initiatives have strengthened our portfolio, are increasing vertical integration and created significant operational efficiencies. With our broad portfolio of packaging solutions and self-help initiatives, we are well positioned to capitalize on the opportunities ahead.”

Consolidated Financial Results

WestRock’s performance for the three months ended December 31, 2023 and 2022 (in millions):

	Three Months Ended
	Dec. 31, 2023			Dec. 31, 2022

Net sales	$	4,620.0		$	4,923.1
Net (loss) income	$	(22.4	)	$	45.3
Consolidated Adjusted EBITDA	$	570.7		$	652.1

The decline in net sales compared to the first quarter of fiscal 2023 was driven primarily by a $205 million, or 18.3%, decrease in Global Paper segment sales and a $156 million, or 12.8%, decrease in Consumer Packaging sales. These reductions include the impact of prior year mill and interior partition divestitures. These items were partially offset by an $83 million, or 3.5%, increase in Corrugated Packaging segment sales. The increase in Corrugated Packaging segment sales in the current year quarter includes a full quarter of operations of the Company’s former joint venture in Mexico that were acquired in December 2022 (“Mexico Acquisition”).

Net income declined in the first quarter of fiscal 2024 compared to the prior year quarter primarily due to lower selling price/mix, the impact of increased economic downtime and prior year mill closures, lower volumes excluding the Mexico Acquisition and higher restructuring and other costs, net. These costs were partially offset by increased cost savings and the additional two months of contribution from the Mexico Acquisition.

Net income in the prior year quarter was also impacted by the Mahrt mill work stoppage and a non-cash loss related to the Mexico Acquisition that were partially offset by a gain on foreign currency exchange contract derivatives entered into in anticipation of the Mexico Acquisition and a gain on sale of two URB mills. See Reconciliations of Adjusted Net Income on page 12 for more information.

Consolidated Adjusted EBITDA decreased $81 million, or 12.5%, compared to the first quarter of fiscal 2023, primarily due to lower Global Paper and Consumer Packaging segment Adjusted EBITDA, as well as higher corporate non-allocated expenses.

Additional information about the changes in segment sales and Adjusted EBITDA by segment is included below.

Restructuring and Other Costs, Net

Restructuring and other costs, net during the first quarter of fiscal 2024 were $66 million. The charges were primarily for severance associated with converting plant closures and ongoing costs related to previously closed operations.

Cash Flow Activities

Net cash provided by operating activities was $275 million in the first quarter of fiscal 2024 compared to $266 million in the prior year quarter.

Total debt was $8.7 billion at December 31, 2023, and Adjusted Net Debt was $8.1 billion. The Company had approximately $3.4 billion of available liquidity from long-term committed credit facilities and cash and cash equivalents at December 31, 2023.

During the first quarter of fiscal 2024, WestRock invested $247 million in capital expenditures and returned $78 million in capital to stockholders in dividend payments.

Segment Results

WestRock’s segment performance for the three months ended December 31, 2023 and 2022 was as follows (in millions):

Corrugated Packaging Segment

	Three Months Ended
	Dec. 31, 2023		Dec. 31, 2022

Segment sales	$	2,419.9	$	2,337.4
Adjusted EBITDA	$	327.8	$	329.4
Adjusted EBITDA Margin		13.5%		14.1%

Corrugated Packaging segment sales increased primarily due to the additional two months of sales from the Mexico Acquisition that were partially offset by lower selling price/mix and lower volumes excluding the Mexico Acquisition. In addition, the first quarter of fiscal 2024 included $42 million of segment sales for certain converting operations that were included in the Consumer Packaging segment in the prior year period.

Corrugated Packaging Adjusted EBITDA decreased primarily due to the margin impact of lower selling price/mix that was partially offset by increased cost savings, the incremental two months of contribution from the Mexico Acquisition, the net impact of lower economic downtime and prior year mill closures and net cost deflation, each as compared to the prior year period. Corrugated Packaging Adjusted EBITDA margin was 13.5% and Adjusted EBITDA margin excluding trade sales was 14.0%.

Consumer Packaging Segment

	Three Months Ended
	Dec. 31, 2023		Dec. 31, 2022

Segment sales	$	1,059.3	$	1,215.0
Adjusted EBITDA	$	166.2	$	183.3
Adjusted EBITDA Margin		15.7%		15.1%

Consumer Packaging segment sales decreased primarily due to lower volumes and the prior year divestiture of our interior partition operations. In addition, the first quarter of fiscal 2023 included $38 million of segment sales for certain converting operations now included in the Corrugated Packaging segment. These items were partially offset by higher selling price/mix and the favorable impact of foreign currency.

Consumer Packaging Adjusted EBITDA decreased primarily due to lower volumes, the impact of increased economic downtime, net cost inflation and the prior year divestiture of our interior partition operations. In addition, the first quarter of fiscal 2023 included $4 million of Adjusted EBITDA for certain converting operations now included in the Corrugated Packaging segment. These items were largely offset by increased cost savings and the margin impact from higher selling price/mix, each as compared to the prior year period. Consumer Packaging Adjusted EBITDA margin was 15.7%.

Global Paper Segment

	Three Months Ended
	Dec. 31, 2023		Dec. 31, 2022

Segment sales	$	918.3	$	1,123.6
Adjusted EBITDA	$	118.4	$	157.3
Adjusted EBITDA Margin		12.9%		14.0%

Global Paper segment sales decreased primarily due to lower selling price/mix, lower volumes and the impact of prior year divested mill operations. Additionally, segment sales are lower than the prior year period because sales to the operations acquired in the Mexico Acquisition were eliminated for a full quarter in the current year period compared to only one month in the prior year quarter.

Global Paper Adjusted EBITDA decreased primarily due to the margin impact of lower selling price/mix, the impact of increased economic downtime and prior year mill closures, the impact of prior year divested mill operations and lower volumes, which were partially offset by increased cost savings, net cost deflation and lower planned maintenance downtime, each as compared to the prior year period. Global Paper Adjusted EBITDA margin was 12.9%.

Distribution Segment

	Three Months Ended
	Dec. 31, 2023		Dec. 31, 2022

Segment sales	$	289.7	$	321.5
Adjusted EBITDA	$	9.0	$	10.8
Adjusted EBITDA Margin		3.1%		3.4%

Distribution segment sales decreased primarily due to lower volumes that were partially offset by higher selling price/mix.

Distribution Adjusted EBITDA decreased primarily due to lower volumes and increased cost inflation, which were partially offset by increased cost savings and the margin impact of higher selling price/mix, each as compared to the prior year period.

Conference Call and Financial Guidance for Subsequent Periods

Due to the proposed business combination with Smurfit Kappa Group plc to create a global leader in sustainable packaging (the “Transaction”), WestRock will not host a conference call to discuss its financial results for the fiscal first quarter ended December 31, 2023. A slide presentation and other relevant financial and statistical information along with this release, can be accessed at ir.westrock.com.

Preparations for the Transaction, including regulatory submissions, are currently underway, and WestRock now expects the Transaction to close in early July 2024. To avoid a delay in this anticipated timeline caused by the inclusion of financial guidance after the second fiscal quarter in certain of those submissions, WestRock does not intend to provide such guidance for subsequent periods.

Definitions, Non-GAAP Financial Measures and Reconciliations

We calculate cost savings as the year-over-year change in certain costs incurred for manufacturing, procurement, logistics, and selling, general and administrative, in each case excluding the impact of economic downtime and inflation. Cost savings achieved to date may not recur in future periods, and estimates of future savings are subject to change.

WestRock reports its financial results in accordance with accounting principles generally accepted in the United States ("GAAP"). However, management believes certain non-GAAP financial measures provide additional meaningful financial information that may be relevant when assessing our ongoing performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, WestRock’s GAAP results. The non-GAAP financial measures we present may differ from similarly captioned measures presented by other companies.

Business Systems Transformation Costs

In the fourth quarter of fiscal 2022, WestRock launched a multi-year phased business systems transformation project. Due to the nature, scope and magnitude of this investment, management believes these incremental transformation costs are above the normal, recurring level of spending for information technology to support operations. Since these strategic investments, including incremental nonrecurring operating costs, will cease at the end of the investment period, are not expected to recur in the foreseeable future, and are not considered representative of our underlying operating performance, management believes presenting these costs as an adjustment in the non-GAAP results provides additional information to investors about trends in our operations and is useful for period-over-period comparisons. This presentation also allows investors to view our underlying operating results in the same manner as they are viewed by management.

We discuss below details of the non-GAAP financial measures presented by us and provide reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated in accordance with GAAP.

Consolidated Adjusted EBITDA and Adjusted EBITDA

WestRock uses the non-GAAP financial measure “Consolidated Adjusted EBITDA,” along with other measures such as “Adjusted EBITDA” (a measure of performance the Company uses to evaluate segment results in accordance with Accounting Standards Codification 280 (“ASC 280”)), to evaluate our overall performance. Management believes that the most directly comparable GAAP measure to “Consolidated Adjusted EBITDA” is “Net (loss) income attributable to common stockholders”. It can also be derived by adding together each segment’s “Adjusted EBITDA” plus “Non-allocated expenses.” Management believes this measure provides WestRock’s management, board of directors, investors, potential investors, securities analysts and others with useful information to evaluate WestRock’s performance because it excludes restructuring and other costs, net, business systems transformation costs and other specific items that management believes are not indicative of the ongoing operating results of the business. WestRock’s management and board use this information in making financial, operating and planning decisions and when evaluating WestRock’s performance relative to other periods.

Adjusted EBITDA, a measure of segment performance in accordance with ASC 280, is defined as pretax earnings of a reportable segment before depreciation, depletion and amortization, and excludes the following items the Company does not consider part of our segment performance: restructuring and other costs, net, non-allocated expenses, interest expense, net, other (expense) income, net, gain on sale of RTS and Chattanooga and other adjustments - each as outlined in the table on page 7 (“Adjusted EBITDA”). The composition of Adjusted EBITDA is not addressed or prescribed by GAAP.

Adjusted Segment Sales and Adjusted EBITDA Margin, Excluding Trade Sales

WestRock uses the non-GAAP financial measures “Adjusted Segment Sales” and “Adjusted EBITDA Margin, excluding trade sales.” Management believes that adjusting segment sales for trade sales is consistent with how our peers present their sales for purposes of computing segment margins and helps WestRock’s management, board of directors, investors, potential investors, securities analysts and others compare companies in the same peer group. Management believes that the most directly comparable GAAP measure to “Adjusted Segment Sales” is “segment sales.” Additionally, the most directly comparable GAAP measure to “Adjusted EBITDA Margin, excluding trade sales” is “Adjusted EBITDA Margin.” “Adjusted EBITDA Margin, excluding trade sales” is calculated by dividing that segment’s Adjusted EBITDA by Adjusted Segment Sales. “Adjusted EBITDA Margin” is a profitability measure in accordance with ASC 280, and it is calculated for each segment by dividing that segment’s Adjusted EBITDA by segment sales.

Adjusted Net Income and Adjusted Earnings Per Diluted Share

WestRock uses the non-GAAP financial measures “Adjusted Net Income” and “Adjusted Earnings Per Diluted Share”. Management believes these measures provide WestRock’s management, board of directors, investors, potential investors, securities analysts and others with useful information to evaluate WestRock’s performance because they exclude restructuring and other costs, net, business systems transformation costs and other specific items that management believes are not indicative of the ongoing operating results of the business. WestRock and its board of directors use this information in making financial, operating and planning decisions and when evaluating WestRock’s performance relative to other periods. WestRock believes that the most directly comparable GAAP measures to Adjusted Net Income and Adjusted Earnings Per Diluted Share are Net (loss) income attributable to common stockholders and (Loss) earnings per diluted share, respectively.

Adjusted Net Debt

WestRock uses the non-GAAP financial measure “Adjusted Net Debt”. Management believes this measure provides WestRock’s board of directors, investors, potential investors, securities analysts and others with useful information to evaluate WestRock’s repayment of debt relative to other periods because it includes or excludes certain items management believes are not comparable from period to period. Management believes “Adjusted Net Debt” provides greater comparability across periods by adjusting for cash and cash equivalents, as well as fair value of debt step-up included in Total Debt that is not subject to debt repayment. WestRock believes that the most directly comparable GAAP measure is “Total Debt” which is the sum of the current portion of debt and long-term debt due after one year.

This release includes reconciliations of our non-GAAP financial measures to their respective directly comparable GAAP measures, as identified above, for the periods indicated (in millions, except percentages and dollars per share).

Forward-looking statements involve estimates, expectations, projections, goals, targets, forecasts, assumptions, risks and uncertainties. A forward-looking statement is not a guarantee of future performance, and actual results could differ materially from those contained in the forward-looking statement. Forward-looking statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond our control, such as developments related to pricing cycles and volumes; economic, competitive and market conditions generally, including macroeconomic uncertainty, customer inventory rebalancing, the impact of inflation and increases in energy, raw materials, shipping, labor and capital equipment costs; reduced supply of raw materials, energy and transportation, including from supply chain disruptions and labor shortages; intense competition; results and impacts of acquisitions, including operational and financial effects from the acquisition of the remaining stake in Grupo Gondi (the “Mexico Acquisition”), and divestitures; business disruptions, including from the occurrence of severe weather or a natural disaster or other unanticipated problems, such as labor difficulties, equipment failure or unscheduled maintenance and repair, or public health crises; failure to respond to changing customer preferences and to protect our intellectual property; the amount and timing of capital expenditures, including installation costs, project development and implementation costs, and costs related to resolving disputes with third parties with which we work to manage and implement capital projects; risks related to international sales and operations; the production of faulty or contaminated products; the loss of certain customers; adverse legal, reputational, operational and financial effects resulting from information security incidents and the effectiveness of business continuity plans during a ransomware or other cyber incident; work stoppages and other labor relations difficulties; inability to attract, motivate and retain qualified personnel, including as a result of the proposed business combination with Smurfit Kappa plc (the "Transaction"); risks associated with sustainability and climate change, including our ability to achieve our sustainability targets and commitments and realize climate-related opportunities on announced timelines or at all; our inability to successfully identify and make performance improvements and deliver cost savings and risks associated with completing strategic projects on anticipated timelines and realizing anticipated financial or operational improvements on announced timelines or at all, including with respect to our business systems transformation; risks related to the proposed Transaction, including our ability to complete the Transaction on the anticipated timeline, or at all, restrictions imposed on our business under the Transaction agreement, disruptions to our business while the proposed Transaction is pending, the impact of management’s time and attention being focused on consummation of the proposed Transaction, costs associated with the proposed Transaction, and integration difficulties; risks related to our indebtedness, including increases in interest rates; the scope, costs, timing and impact of any restructuring of our operations and corporate and tax structure; the scope, timing and outcome of any litigation, claims or other proceedings or dispute resolutions and the impact of any such litigation (including with respect to the Brazil tax liability matter); and additional impairment charges. Such risks and other factors that may impact forward-looking statements are discussed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023, including in Item 1A “Risk Factors”, as well as in our subsequent filings with the Securities and Exchange Commission. The information contained herein speaks as of the date hereof, and the Company does not have or undertake any obligation to update or revise its forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by law. Non-GAAP Financial Measures: We report our financial results in accordance with accounting principles generally accepted in the United States (“GAAP”). However, management believes certain non-GAAP financial measures provide users with additional meaningful financial information that should be considered when assessing our ongoing performance. Management also uses these non-GAAP financial measures in making financial, operating and planning decisions and in evaluating our performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our GAAP results. The non-GAAP financial measures we present may differ from similarly captioned measures presented by other companies. For additional information, see the Appendix. In addition, as explained in the Appendix, we are not providing a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable U.S. GAAP measure because we are unable to predict with reasonable certainty the ultimate outcome of certain significant items without unreasonable effort.

Non-GAAP Financial Measures Adjusted Earnings Per Diluted Share We use the non-GAAP financial measure “Adjusted Earnings per Diluted Share,” also referred to as “Adjusted Earnings per Share” or “Adjusted EPS”, because we believe this measure provides our management, board of directors, investors, potential investors, securities analysts and others with useful information to evaluate our overall performance since it excludes restructuring and other costs, impairment of goodwill and mineral rights, business systems transformation costs, and other specific items that we believe are not indicative of our ongoing operating results. Our management and board of directors use this information in making financial, operating and planning decisions and when evaluating our performance related to other periods. We believe the most directly comparable GAAP measure is “Diluted (loss) earnings per share”. Adjusted Operating Cash Flow and Adjusted Free Cash Flow We use the non-GAAP financial measures “Adjusted Operating Cash Flow” and “Adjusted Free Cash Flow” because we believe these measures provide our management, board of directors, investors, potential investors, securities analysts and others with useful information to evaluate our overall performance relative to other periods because they exclude certain cash restructuring and other costs, net of tax and business systems transformation costs, net of tax that we believe are not indicative of our ongoing operating results. We believe Adjusted Free Cash Flow provides greater comparability across periods by excluding capital expenditures. We believe the most directly comparable GAAP measure is “Net cash provided by operating activities”. Consolidated Adjusted EBITDA and Consolidated Adjusted EBITDA Margins We use the non-GAAP financial measures “Consolidated Adjusted EBITDA” and “Consolidated Adjusted EBITDA Margins”, along with other measures in making financial, operating and planning decisions and when evaluating our performance related to other periods. We believe that our management, board of directors, investors, potential investors, securities analysts and others use these measures to evaluate our overall performance. Management believes that the most directly comparable GAAP measure to “Consolidated Adjusted EBITDA” is “Net (loss) income attributable to common stockholders”. It can also be derived by adding together each segment’s “Adjusted EBITDA” plus “Non-allocated expenses”. “Consolidated Adjusted EBITDA Margins” is calculated as “Consolidated Adjusted EBITDA” divided by Net Sales. Corrugated Adjusted EBITDA Margin, Excluding Trade-Sales “Corrugated Adjusted EBITDA Margin, Excluding Trade Sales” is computed by dividing “Corrugated Adjusted EBITDA” by corrugated segment sales, excluding trade-sales, which is reported segment sales less trade-sales. Packaging Adjusted EBITDA Margin “Packaging Adjusted EBITDA Margin” is a non-GAAP financial measure and consists of the sum of “Corrugated Packaging segment Adjusted EBITDA” and “Consumer Packaging segment Adjusted EBITDA” divided by the sum of “Corrugated Packaging segment sales (excluding trade sales)” and “Consumer Packaging segment sales”. Consumer Packaging Net Organic Sales Volume “Consumer Net Organic Sales Volume” is a non-GAAP financial measure and is computed by subtracting the revenue impact of transferred operations, acquisitions, divestitures, price/mix and foreign exchange rate fluctuations from “Segment Sales”. Leverage Ratio, Net Leverage Ratio, Total Funded Debt and Adjusted Total Funded Debt We use the non-GAAP financial measures “Leverage Ratio” and “Net Leverage Ratio” as measurements of our operating performance and to compare to our publicly disclosed target leverage ratio. We believe our management, board of directors, investors, potential investors, securities analysts and others use each measure to evaluate our available borrowing capacity – in the case of “Net Leverage Ratio”, adjusted for cash and cash equivalents. We define Leverage Ratio as our Total Funded Debt divided by our credit agreement EBITDA, each of which term is defined in our revolving credit agreement, dated July 7, 2022, with Wells Fargo as administrative agent. While the Leverage Ratio under our credit agreement determines the credit spread on our debt, we are not subject to a leverage ratio cap. We define “Adjusted Total Funded Debt” as our Total Funded Debt less cash and cash equivalents. Net Leverage Ratio represents Adjusted Total Funded Debt divided by our credit agreement EBITDA. See calculations on slide 27 for each of these ratios as of December 31, 2023.
