INFORMATION CONTAINED IN THIS FORM 6-K REPORT

Share Purchase Agreement

On August 27, 2026, LogProstyle Inc. (the “Company”) entered into a Share Purchase Agreement (the “Share Purchase Agreement”) with Toshihide Suzuki (the “Seller”), pursuant to which the Company agreed to acquire from the Seller all 3,800 issued and outstanding shares of I-FLATZ Co., LTD. a Japanese corporation (“I-FLATZ”) for an aggregate purchase price of JPY 612,692,000 (the “Purchase Price”). I-FLATZ is the sole shareholder of LAND-I Co., LTD. a Japanese Corporation (“LAND-I,” with I-FLATZ and LAND-I referred to together as the “Target Company Group”). Upon completion of the transactions contemplated by the Share Purchase Agreement, I-FLATZ will become a wholly owned subsidiary of the Company.

The closing of the Share Purchase Agreement is expected to occur on or about September 30, 2026, or such other date as may be agreed upon by the parties. At the closing, the Seller will deliver to the Company the share certificates representing the shares of I-FLATZ against payment of the Purchase Price by the Company.

The Share Purchase Agreement contains customary representations, warranties and covenants of the Company and the Seller. Prior to the closing, the Seller is required, among other things, to cause the Target Company Group to operate its business in the ordinary course and is restricted from causing the Target Company Group to take certain specified actions without the Company’s prior written consent. The Seller is also required to complete certain corporate and other actions prior to closing, including actions relating to the Target Company Group’s historical corporate approvals, officer retirement benefits, shareholder registers and certain management arrangements.

The parties’ respective obligations to consummate the Share Purchase Agreement are subject to customary closing conditions, including the accuracy of the applicable representations and warranties and performance of the parties’ respective pre-closing obligations. The Company’s obligation to close is also conditioned upon, among other things, the absence of an event that threatens to have a material adverse effect on the Target Company Group, and the execution and continued effectiveness of certain management delegation agreements and consent letters.

Following the closing, the Seller will be subject to certain non-competition and employee non-solicitation restrictions. The Company has also agreed, among other things, to procure the release or equivalent discharge, within two months following the closing, of certain personal guarantees provided by the Seller with respect to specified borrowings of I-FLATZ and, subject to specified exceptions, to continue the employment of I-FLATZ’ employees and maintain their existing working conditions.

The Share Purchase Agreement also contains customary indemnification provisions. The Seller generally is required to indemnify the Company for losses resulting from the Seller’s breach of the Share Purchase Agreement, including breaches of the Seller’s representations and warranties. Claims relating to breaches of general representations and warranties are generally subject to a JPY 5 million threshold, a 1-year survival period following the closing, and an aggregate liability cap equal to 50% of the Purchase Price, while certain fundamental representations and warranties are excluded from the threshold and survival limitations and are subject to an aggregate liability cap of 100% of the Purchase Price. The Share Purchase Agreement also provides for special indemnification by the Seller with respect to claims by third parties asserting ownership or other rights in the shares being acquired.

The Share Purchase Agreement may be terminated prior to closing in specified circumstances, including certain uncured breaches, insolvency events or if the closing has not occurred by the date specified in the Share Purchase Agreement. The Share Purchase Agreement is governed by Japanese law, and the Tokyo District Court has exclusive jurisdiction over disputes arising thereunder.

There can be no assurance that the Share Purchase Agreement will close as planned, or at all.

The foregoing description of the Share Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Share Purchase Agreement, a convenience English language translation of which is filed as Exhibit 10.1 to this Report on Form 6-K and is incorporated herein by reference.
