## Exhibit 99.1

**Exhibit 99.1**

**J-Star Holding Announces Receipt of Nasdaq Delisting Determination; Class A Ordinary Shares Expected to Continue Trading Pending Nasdaq Hearings Panel Review**

 

Taichung City, Taiwan – June 15, 2026 — J-Star Holding Co., Ltd. (Nasdaq: YMAT) ("J-Star" or the "Company"), today announced that on June 12, 2026, it received a Staff Delisting Determination Letter from the staff of The Nasdaq Stock Market LLC ("Nasdaq") indicating that the Company is not in compliance with Nasdaq Listing Rule 5550(a)(2), which requires listed companies to maintain a minimum bid price of $1.00 per share.

As previously disclosed, the Company received notice from Nasdaq on December 12, 2025, that it was not in compliance with the minimum bid price requirement and was provided a compliance period through June 10, 2026 to regain compliance and is not eligible for the second 180-day compliance period.

The Company intends to timely request an oral hearing before the Nasdaq Hearings Panel (the "Panel") pursuant to Nasdaq Listing Rule 5815. The hearing request will stay the suspension of trading or delisting action pending the Panel's decision. Accordingly, the Company's Class A ordinary shares are expected to continue trading on the Nasdaq Capital Market under the symbol "YMAT" during the hearing process.

The Company intends to submit a plan to the Panel outlining its actions to regain compliance with the Nasdaq listing standards and will request an exception permitting additional time to regain compliance, as allowed under applicable Nasdaq rules. However, there can be no assurance that the Panel will grant the Company's request for continued listing or any additional exception period, or that the Company will ultimately regain compliance with all applicable Nasdaq listing requirements.

This announcement is made in accordance with Nasdaq Listing Rule 5810(b), which requires prompt public disclosure of receipt of a delisting determination.
