Stalking Horse Asset Purchase Agreement

On June 12, 2026, the Company entered into a “stalking horse” Asset Purchase Agreement (the “Stalking Horse Purchase Agreement”) with SNBR, Inc., a wholly-owned subsidiary of Sleep Country Canada Inc. (in such capacity, the “Purchaser”) and Sleep Country Canada Inc. pursuant to which the Purchaser agreed to purchase substantially all of the assets of the Company (such assets, the “Assets,” and such transaction, the “Asset Sale”) for a purchase price of $415 million in cash and the assumption of certain liabilities, subject to certain potential purchase price adjustments, in each case, as set forth in the Purchase Agreement. The Assets to be acquired pursuant to the Asset Sale do not include, among other things, any executory leases or contracts that the Purchaser chooses to reject or are otherwise rejected in the Chapter 11 Cases. Based on the purchase price in the Stalking Horse Purchase Agreement, the common shares are significantly out of the money and would likely have no recovery.

Upon Bankruptcy Court approval, the Purchaser is expected to be approved as the “stalking horse” bidder in connection with the Asset Sale under section 363 of the Bankruptcy Code. The Asset Sale will be conducted through a Bankruptcy Court-supervised process pursuant to Bankruptcy Court-approved bidding procedures. The Asset Sale is subject to the receipt of higher or otherwise better offers from competing bidders at an auction (if applicable), approval of the Asset Sale by the Bankruptcy Court, and certain other conditions set forth in the Purchase Agreement.

The Purchase Agreement contains customary representations, warranties and covenants of the parties for a transaction involving the acquisition of assets from a debtor in bankruptcy, and the completion of the Asset Sale is subject to a number of conditions, which, among others, include (i) the entry of an order of the Bankruptcy Court authorizing and approving the Asset Sale, (ii) the performance by each party of its obligations under the Purchase Agreement (subject to certain materiality qualifiers), (iii) the accuracy of each party’s representations (subject to certain materiality qualifiers), (iv) the delivery of certain closing deliverables, (v) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (vi) the absence of any judicial or administrative proceeding by the Federal Trade Commission or the United States Department of Justice Antitrust Division that seeks to prevent, restrain, enjoin or prohibit the Asset Sale under antitrust laws, and (vii) the absence of any order by any governmental authority that restrains, enjoins, stays, or prohibits the consummation of the Asset Sale. The obligation of the Purchaser to consummate the Asset Sale is also conditioned upon the Company having not experienced a material adverse effect. The Purchase Agreement also provides for a break-up fee and expense reimbursement payable to the Purchaser upon the occurrence of certain events, and the forfeiture of a deposit to the Company upon the occurrence of certain events.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Purchase Agreement filed hereto as Exhibit 2.1.

Item 2.04 Triggering Events that Accelerate or Increase a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement.

As discussed in Item 1.03, on the Petition Date, the Debtors filed the Chapter 11 Cases in the Bankruptcy Court seeking relief under chapter 11 of title 11 of the Bankruptcy Code. The Debtors continue to operate their business and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The commencement of the Chapter 11 Cases constituted an event of default under the Prepetition Credit Agreement enumerated below, resulting in the acceleration of the Company’s payment obligations under those instruments. As such, substantially all of the Company’s debt, with balances of approximately $672.5 million in the aggregate principal amount as of the Petition Date, is in default and accelerated, but subject to the automatic stay under the Bankruptcy Code.

The filing of the Chapter 11 Cases constituted an event of default that accelerated the Debtors’ obligations under that certain Amended and Restated Credit and Security Agreement, dated February 18, 2018 (as amended, restated, or otherwise modified or supplemented through that certain Forbearance Agreement and Thirteenth Amendment to the Amended and Restated Credit and Security Agreement, dated as of April 27, 2026, the “Prepetition Credit Agreement”), between, amongst others, the Company as Borrower, the Lenders named therein and U.S. Bank National Association as Administrative Agent.

The Prepetition Credit Agreement described above provides that, as a result of the commencement of the Chapter 11 Cases, any principal amount, together with accrued interest thereon, are immediately due and payable. However, any efforts to enforce the payment obligations under the Prepetition Credit Agreement and such other instruments and agreements are automatically stayed as a result of the Chapter 11 Cases, and the creditors’ rights of enforcement in respect of the Prepetition Credit Agreement and such other instruments and agreements are subject to the applicable provisions of the Bankruptcy Code.

The disclosure in Item 1.03 of this Current Report on Form 8-K is incorporated herein by reference.

Item 7.01 Regulation FD Disclosure.

Press Release Regarding Bankruptcy Petitions

On June 12, 2026, the Company issued a press release announcing the filing of the Bankruptcy Petitions. A copy of the press release is furnished herewith as Exhibit 99.1 to this Form 8-K and incorporated herein by reference.

Cautionary Note Regarding the Company’s Common Shares

The Company cautions that trading in its securities (including, without limitation, the Company’s common shares) during the pendency of the Chapter 11 Cases is highly speculative and poses substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual recovery, if any, by holders of the Company’s securities in the Chapter 11 Cases. The Company expects that holders of shares of the Company’s common shares will experience a complete or significant loss on their investment, depending on the outcome of the Chapter 11 Cases. Based on the purchase price in the Stalking Horse Purchase Agreement, the common shares are significantly out of the money and would have no recovery. Additionally, as a result of the Chapter 11 Cases, the Company expects that its common shares will be delisted from trading on the Nasdaq.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K and the Exhibits hereto contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which are subject to risks, uncertainties and assumptions that are difficult to predict. Forward-looking statements are predictions based on our current expectations and our projections about future events, and are not statements of historical fact. Forward-looking statements include statements concerning our business strategy, among other things, including anticipated trends and developments in, and management plans for, our business and the markets in which we operate. In some cases, you can identify these

statements by forward-looking words, such as “estimate,” “expect,” “anticipate,” “project,” “plan,” “intend,” “believe,” “forecast,” “foresee,” “likely,” “may,” “should,” “goal,” “target,” “might,” “will,” “could,” “predict,” and “continue,” the negative or plural of these words and other comparable terminology. All forward-looking statements included in this Form 8-K are based upon information available to us as of the filing date of this Form 8-K, and we undertake no obligation to update any of these forward-looking statements for any reason. You should not place undue reliance on these forward-looking statements. These forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to differ materially from those expressed or implied by these statements. These factors include the matters discussed in “Part I - Item 1A - Risk Factors” in our Annual Report on Form 10-K for the year ended January 3, 2026 as well as the additional factors included below. You should carefully consider the risks and uncertainties described under these sections.

A wide range of factors relating to the Chapter 11 Cases could materially affect future developments and performance, including but not limited to:

• our ability to continue as a going concern; • our ability to successfully consummate the planned sale of the business pursuant to Section 363 of the Bankruptcy Code to any potential acquirer through an auction process in Chapter 11 and if consummated, to obtain an adequate price; • our ability to successfully complete a reorganization under Chapter 11 and emerge from bankruptcy; • the effects of the Chapter 11 Cases on us and on the interests of various constituents; • bankruptcy court rulings in the Chapter 11 Cases and the outcome of the Chapter 11 Cases in general; • the length of time the Company will operate under the Chapter 11 Cases; • risks associated with third-party motions in the Chapter 11 Cases; • the potential adverse effects of the Chapter 11 Cases on our liquidity and results of operations; • increased legal and other professional costs necessary to execute our reorganization; • the conditions to which our debtor-in-possession financing is subject, and the risk that these conditions may not be satisfied for various reasons, including for reasons outside of our control; • the consequences of the acceleration of our debt obligations; • employee attrition and our ability to retain senior management and key personnel due to the distractions and uncertainties, including our ability to provide adequate compensation and benefits during the Chapter 11 Cases; • our ability to comply with the restrictions imposed by the DIP Amendment; • the likely cancellation of our common shares in the Chapter 11 Cases; • the potential material adverse effect of claims that are not discharged in the Chapter 11 Cases; • the diversion of management’s attention as a result of the Chapter 11 Cases; and • volatility of our financial results as a result of the Chapter 11 Cases.
