Insights

M&A Counsel

Regulatory and closing conditions remain the key gating items.

The filing confirms the HSR waiting period has expired as of June 3, 2026, removing that specific U.S. antitrust wait‑time obstacle. Material remaining conditions include shareholder approval, foreign competition clearances (Canada, EU, UK, Korea) and Form S-4 effectiveness.

Watch for the definitive proxy statement/prospectus and any regulatory conditions in the Form S-4 filing; timing depends on the pace of foreign clearances and the S-4 review.

Corporate Finance Advisor

Transaction timing and capital structure outcomes hinge on disclosed approvals and S-4 mechanics.

The report states an expected close by year-end 2026, but conditions include foreign competition approvals and the absence of material adverse effects. The Form S-4 will disclose financing, share issuance terms and pro forma capital structure.

Subsequent filings will clarify funding sources, anticipated leverage and any commitments; until the S-4 is filed, material capital and cash‑flow impacts are not specified.

Form S-4 regulatory

"the effectiveness of a registration statement on Form S-4 to be filed by Parent"

A Form S-4 is a legal document that companies file with the government to announce and explain a major business move, such as a merger or acquisition. It provides detailed information to help investors understand how the deal might affect the company's value and future prospects, similar to a detailed blueprint that clarifies the impact of a significant change.

Hart-Scott-Rodino regulatory

"the required 30-day waiting period under the Hart-Scott-Rodino Antitrust Improvements Act"

The Hart-Scott-Rodino Antitrust Act is a U.S. law that requires companies to notify federal regulators and wait for a review before closing large mergers or acquisitions. Think of it as a required heads-up and cooling-off period so antitrust officials can check whether a deal would unfairly reduce competition; for investors this can delay or block transactions and change the risk, timing, and expected value of corporate deals.

proxy statement/prospectus regulatory

"the Form S-4 that will include a proxy statement of the Company and that will also constitute a prospectus of Parent"

A proxy statement or prospectus is a document that companies send to shareholders to provide important information about upcoming decisions or investments, such as voting on company issues or offering new shares to the public. It helps investors understand the details and risks involved, enabling them to make informed choices about their ownership or involvement with the company.

FORWARD-LOOKING STATEMENTS

This Current Report, including the information incorporated by reference herein, contains statements that may be characterized as “forward-looking” within the meaning of the federal securities laws. Such statements might include information concerning one or more of Parent’s and the Company’s plans, guidance, objectives, goals, strategies, and other information that is not historical information. When used in this Current Report, the words “will,” “targets,” “expects,” “anticipates,” “plans,” “proposed,” “intends,” “outlook,” and variations of such words or similar expressions are intended to identify forward-looking statements. These forward-looking statements include, without limitation, statements relating to Parent’s expectations regarding the impact of the proposed transaction on Parent’s brands, products, customer base, results of operations, or financial position, its share repurchases, adjusted EPS, net leverage, operating cash flow, net income, future performance, cost and run-rate synergies, funding sources, expected capital structure, the financial impact of the Company’s existing long-term debt, ability to deleverage after the proposed transaction, the expected timing and likelihood of completion of the proposed transaction, the integration of the Company with Parent’s business and personnel and Parent’s and the Company’s post-acquisition financial reporting. Any forward-looking statements contained herein are based upon current expectations and beliefs and various assumptions. There can be no assurance that these expectations or beliefs will prove correct.

Numerous factors, many of which are beyond Parent’s and the Company’s control, could cause actual results to differ materially from any that may be expressed herein as forward-looking statements. These potential risks include risks associated with the Company’s ongoing operations; the ability to obtain the requisite Company shareholder approval; the risk that Parent or the Company may be unable to obtain governmental and regulatory approvals required for the proposed transaction (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction); the risk that an event, change or other circumstance

could give rise to the termination of the proposed transaction; the risk of delays in completing the proposed transaction; the ability to successfully integrate the Company into Parent’s operations and realize synergies from the proposed transaction and the expected run-rate of such synergies; the possibility that the expected benefits of the acquisition are not realized when expected or at all; the risk that any announcement relating to the proposed transaction could have adverse effects on the market price of Parent common stock or Company common stock; the risk of litigation related to the proposed transaction; the diversion of management time from ongoing business operations and opportunities as a result of the proposed transaction; the risk of adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction; general economic, financial and industry conditions, particularly conditions relating to the financial performance and related credit issues present in the retail sector, as well as consumer confidence and the availability of consumer financing; the impact of the macroeconomic environment in both the U.S. and internationally on Parent and the Company; uncertainties arising from national and global events; industry competition; the effects of consolidation of retailers on revenues and costs; consumer acceptance and changes in demand for Parent’s and the Company’s products; and other risks inherent in Parent’s and the Company’s businesses.

All such factors are difficult to predict, are beyond Parent’s and the Company’s control and are subject to additional risks and uncertainties, including those detailed in Parent’s annual report on Form 10-K for the year ended December 31, 2025 and those detailed in the Company’s annual report on Form 10-K for the year ended December 31, 2025 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2026. These risks, as well as other risks related to the proposed transaction, will be included in the Form S-4 and proxy statement/prospectus (each as defined below) that Parent and the Company intend to file with the SEC in connection with the proposed transaction. There may be other factors that may cause Parent’s and the Company’s actual results to differ materially from the forward-looking statements. Neither Parent nor the Company undertakes any obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof.
