Item 1.02. Termination of a Material Definitive Agreement.

As previously reported, on November 28, 2021, Boxed, Inc. (then known as Seven Oaks Acquisition Corp.; the "Company") and ACM ARRT VII D LLC (the "Seller") entered into an agreement (the "Agreement") for a cash-settled OTC Equity Prepaid Forward Transaction, pursuant to which $65.1 million (the "Prepayment Amount") was paid into a deposit account for the benefit of the Seller, in connection with the consummation of the Company's business combination transaction, to be held in accordance with the terms of the Agreement until the end of the Valuation Period (as defined in the Agreement).

As previously reported on the Company's Quarterly Report on Form 10-Q for the period ended June 30, 2022 (the "Form 10-Q"), on July 6, 2022, the volume weighted average trading price (the "VWAP") of the Company's common stock, par value $0.0001 per share (the "Common Stock"), fell below $5.00 per share for 20 out of 30 consecutive trading days (a "VWAP Trigger Event"). Pursuant to the terms of the Agreement, on August 11, 2022, the Seller notified the Company of the occurrence of the VWAP Trigger Event and the Seller's election to accelerate the commencement date of the Valuation Period to August 16, 2022.

As previously reported in the Form 10-Q, with respect to the Agreement, as of June 30, 2022, the Company had recorded a forward purchase receivable asset of $58.5 million, offset by a forward purchase option derivative liability of $49.1 million in its condensed consolidated balance sheets. The actual amount of the Prepayment Amount repaid to the Seller, and the portion of the Prepayment Account remitted to the Company, will depend on the VWAP of the Common Stock during the Valuation Period.

The foregoing descriptions of certain terms and provisions of the Agreement do not purport to be complete and are qualified in their entirety by the terms and conditions of the full text of the Agreement, which was previously filed as Exhibit 10.1 to the Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission by the Company on November 30, 2021.

The information included in Item 1.02 of this Current Report on Form 8-K (this "Report") is incorporated by reference into this Item 2.04 of this Report.
