IMPLICATION UNDER THE LISTING RULES

PROVISION OF GUARANTEE

Background

On 18 June 2026 (after trading hours), Xin Ke Xin (an indirect wholly owned subsidiary of the Company), as the guarantor, entered into the Guarantee Agreement in favour of the Bank, pursuant to which Xin Ke Xin has agreed to provide guarantee for the due performance of the repayment obligations of the Borrower to the Bank under the Loan Agreement.

The major terms of the Guarantee Agreement are set out as follows:

Date: 18 June 2026

Parties:
(1) Xin Ke Xin (as guarantor); and
(2) the Bank

Guarantee: Xin Ke Xin, as the guarantor, has agreed to provide guarantee of up to RMB120,000,000 in favour of the Bank to secure the due performance of the Borrower’s repayment obligations under the Loan Agreement and any other future loan agreement(s) with principal in aggregate of not more than RMB100,000,000, including, without limitation, with respect to the principal amount under the Loan Agreement together with any interest, default interest, penalty, compensations, liquidated damages and other expenses incurred by the Bank in enforcing its rights under the Guarantee Agreement;

Term of guarantee: 3 years from the maturity date of the Loan under the Loan Agreement (貸款合同約定的債務履行期限屆滿之日起三年)

The major terms of the Loan Agreement are set out as follows:

Date: Proposed to be signed on 22 June 2026

Parties:
(1) the Borrower; and
(2) the Bank

Principal amount: RMB50,000,000

Interest rate: Loan Prime Rate

Term: 1 year from the date of signing to 1 June 2027

REASONS FOR AND BENEFITS OF THE PROVISION OF GUARANTEE

Currently, Xin Ke Xin and its wholly owned subsidiary Nanjing Zhangyu are facing difficulties in obtaining financing from financial institutions, whereas the Borrower is owned as to 5% by state-owned enterprise, which provides a meaningful level of implicit government backing and enhances its overall creditworthiness. The arrangement under the Guarantee Agreement enables Xin Ke Xin and Nanjing Zhangyu to access and secure external financing by leveraging the existing credit line of the Borrower. Furthermore, the Borrower did not charge the Company or Xin Ke Xin (as the guarantor) any fees during the financing process. In view of the aforesaid, the financing structure contemplated under the Guarantee Agreement supports the continued operation and development of Xin Ke Xin and

Nanjing Zhangyu, which in turn is expected to enhance the Group's profitability and financial stability and support the sustainable growth of the Group's two other principal business segments, namely, (i) the integrated circuits and digital technology business segment and (ii) the new energy & services business segment. In addition, as Nanjing Zhangyu's technology is critical to the Borrower's business development, the Borrower's support in allowing its creditworthiness to be used for the benefit of Nanjing Zhangyu and Xin Ke Xin further reinforces the Group's mutual strategic cooperation with the Borrower and is expected to generate long-term synergies and value for the Company and the Shareholders.

The Bank has agreed to provide a loan facility to the Borrower. The principal amount of the loan under the Loan Agreement is RMB50,000,000, being the first loan to be advanced to the Borrower thereunder. As the Guarantee Agreement is a maximum amount guarantee (最高额保證合同), upon utilisation of the first loan of RMB50,000,000, a further loan of up to RMB50,000,000 may be advanced to the Borrower under the same Guarantee Agreement without the need for any separate guarantee, such that the maximum aggregate principal amount of the loans secured by the Guarantee Agreement is RMB100,000,000. Therefore the guarantee of up to RMB120,000,000 to be provided by Xin Ke Xin represents 120% of such maximum aggregate loan principals (i.e. RMB100,000,000), with the additional 20% covering the related interest, default interest, penalties and enforcement costs that may arise under the Guarantee Agreement.

Having considered the above and that the risk exposed to the Group can be managed by adopting appropriate safeguards on the cash and bank balances of the Borrower derived from the Loan Agreement and any other future loan agreement(s) and control measures (including the Company monitoring the use of, and the designated repayment account holding, the proceeds of the Loan pursuant to the relevant contractual arrangements), the Board is of the view that the Guarantee Agreement is determined on normal commercial terms or better and are fair and reasonable and in the interest of the Company and the Shareholders as a whole.
