Entry into a Material Definitive Agreement.

ARC Group International Equity Purchase Agreement

On December 17, 2025, Ruanyun Edai Technology Inc., an exempted company incorporated under the laws of the Cayman Islands (the “Company”) entered into an equity purchase agreement (the “Purchase Agreement”) with ARC Group International Ltd. (“ARC”), the parent of ARC Group Securities, a FINRA registered broker/dealer. Under the terms of the Purchase Agreement, ARC has committed to purchase, from time to time at the Company’s discretion, up to $100,000,000 of the Company’s ordinary shares, par value $0.0002 per share (the “Ordinary Shares”), over a 36-month period (the “Facility”).

Under the Facility, the Company, in its sole discretion and subject to the terms and conditions of the Purchase Agreement, may direct ARC to purchase registered Ordinary Shares at a purchase price equal to a specified discount to the prevailing volume-weighted average price during an agreed pricing period, the discount being between 0.0% and 5.0%. ARC may not purchase shares under the Facility that would result in its beneficial ownership exceeding 4.99% of the Company’s then-outstanding Ordinary Shares and is prohibited from short selling or hedging transactions involving the Company’s securities.

As consideration for ARC’s commitment under the Facility, the Company issued to ARC 1,200,000 Ordinary Shares (the “Commitment Shares”) at a deemed price of $1.10 per share. The Company is required to file one or more registration statements with the Securities and Exchange Commission (the “SEC”) registering the resale of shares issuable under the Facility, and no sales of such shares to ARC may occur unless and until the applicable registration statement is declared effective by the SEC. The Company is not obligated to make any sales under the Facility. As a result of the issuance of the Commitment Shares, ARC now owns 3.49 % of the issued and outstanding Ordinary Shares of the Company.

The foregoing description of the Purchase Agreement is a summary and does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

In connection with the setting up of the Purchase Agreement, the Company issued a press release on December [18], 2025, a copy of which is attached hereto as Exhibit 99.1 and is incorporated by reference herein in its entirety.
