To the Shareholders

Dear Sir or Madam,

PLACING OF NEW SHARES UNDER SPECIFIC MANDATE

INTRODUCTION

Reference is made to the Announcement.

The purpose of this circular is to provide you with, among other things, (i) further details of the Placing Agreement and the transactions contemplated thereunder; and (ii) a notice convening the EGM.


LETTER FROM THE BOARD

THE PLACING

The Board announces that, on 5 March 2026, the Company entered into the Placing Agreement with the Placing Agent, pursuant to which the Company agreed to place through the Placing Agent up to a maximum of 1,000,000,000 Placing Shares to not less than six Placees at the Placing Price of HK$0.108 per Placing Share on a best effort basis.

The Placing Agreement

The principal terms and conditions of the Placing Agreement are summarised as follows:

Date: 5 March 2026

Parties:
(i) the Company; and
(ii) the Placing Agent.

To the best of the Directors’ knowledge, information, and belief, after making all reasonable enquiries, the Placing Agent and its respective ultimate beneficial owner(s) are Independent Third Parties.

The Placing Agent

The Company appoints the Placing Agent, upon and subject to the terms and conditions of the Placing Agreement, as its placing agent to procure not less than six Placee(s) on a best-effort basis at the Placing Price for the Placing Shares on a best effort basis.

As the agent of the Company, on a best-effort basis, the Placing Agent shall procure Placees, who shall be independent of the Company and not connected nor acting in concert with any of the connected persons of the Company or any of their respective associates, during the period from the date of the Placing Agreement up to the Completion Date.

The Placing Agent will take reasonable measures in procuring the Placees during the Placing such that the Company will not fall below the Public Float Requirements immediately after the Placing. Additionally, the Placing Agent will take measures to prevent any Placee from being obliged to make a mandatory general offer to other Shareholders under the Takeovers Code.

Number of the Placing Shares

Assuming that there are no changes in the total issued share capital of the Company between the Latest Practicable Date and the Completion Date, and that all 1,000,000,000 Placing Shares are successfully placed, the Placing Shares will represent (i) 186.61% of the total issued share capital of the Company as at the Latest Practicable Date; and (ii) approximately 65.11% of the total issued share capital of the Company as enlarged by the allotment and issue of the Placing Shares immediately following the Completion.

The aggregate nominal value of all the Placing Shares will be HK$100,000,000.


LETTER FROM THE BOARD

Specific Mandate to issue the Placing Shares

The Placing Shares will be allotted and issued under the Specific Mandate to be approved by way of ordinary resolution(s) by the Shareholders at the EGM.

Ranking of the Placing Shares

The Placing Shares, when allotted and issued, will be free of all encumbrance and rank pari passu in all respects with the Shares in issue on the date of allotment and issue of the Placing Shares.

Placing Price

The Placing Price of HK$0.108 per Placing Share represents:

(a) a discount of approximately 31.2% to the closing price of HK$0.157 per Share as quoted on the Stock Exchange on the Latest Practicable Date;

(b) a discount of approximately 20.0% to the closing price of HK$0.135 per Share as quoted on the Stock Exchange on 5 March 2026, being the date of the Placing Agreement;

(c) a discount of approximately 20.0% to the average closing price of HK$0.135 per Share as quoted on the Stock Exchange for the five trading days immediately preceding the date of the Placing Agreement;

(d) a discount of approximately 42.6% to the Group’s unaudited consolidated net asset value attributable to the Shareholders per Share of approximately HK$0.188 as at 30 September 2025 (based on a total of 535,864,491 Shares as at the Latest Practicable Date and the Group’s unaudited consolidated net asset value of approximately HK$100,822,000 as at 30 September 2025; and

(e) a theoretical dilution effect (as defined under Rule 7.27B of the Listing Rules) represented by a discount of approximately 15.05%, which is calculated based on a theoretical diluted price of approximately HK$0.178 per Share (as defined under Rule 7.27B of the Listing Rules, taking account the higher of (i) the closing price of the Shares quoted on the Stock Exchange on the date of the Placing Agreement of HK$0.135 per Share; and (ii) the average closing prices of the Shares quoted on the Stock Exchange for the five consecutive trading days preceding the date of the Placing Agreement of HK$0.135 per Share).


LETTER FROM THE BOARD

The Placing Price was determined after arm's length negotiations between the Company and the Placing Agent with reference to, among other things, the prevailing market price and the recent trading volume of the Shares. When determining the Placing Price, the Directors have considered the following factors:

(i) the Directors conducted a comprehensive review of the closing price movements of the Shares listed on the Stock Exchange, covering the period from 6 March 2025 to 5 March 2026 (the "Review Period"), which is one year before the date of Placing Agreement. The Directors believe that this one-year timeframe effectively captures the prevailing market sentiment and it captures sufficient market data to reflect both stable and volatile periods, ensuring that the Placing Price is determined based on a comprehensive analysis rather than short-term fluctuations. This duration aligns with recent market trends and price fluctuations, providing a reliable representation of market attitudes toward the Shares. The chart below shows the movement of the closing Share Price during the Review Period.

During the Review Period, the Shares listed on the Stock Exchange reached a peak closing price of HK$0.255 on 13 March 2025, while the lowest closing price was recorded at HK$0.127 on 4 March 2026. The Directors observed a continuous downward trend in the closing share price beginning in June 2025. The Directors do not identify any specific reasons for the fluctuations observed during the Review Period.

Furthermore, the Directors considered that the significant fluctuations in Share price since 16 February 2025, being the trading day immediately after the issuance of results announcement of the Rights Issue creates considerable uncertainty in pricing, complicating efforts for Shareholders to accurately assess the fair value of their Shares through fundamental analysis.

In these situations, Shareholders may expect higher returns as compensation for the increased risks involved. The Directors understand that this volatility creates significant challenges in determining the fair value of shares, which in turn leads to a discount in the Placing Price. This strategy aims to encourage the Placees to subscribe the Placing Shares.


LETTER FROM THE BOARD

(ii) the Directors conducted a review of the trading volume and liquidity of the Shares during the Review Period. Set out below is the table showing (i) the monthly trading volume of the Shares; (ii) the number of trading days of each month; (iii) the average daily trading volume of the Shares; and (iv) the percentage of the average daily trading volume of the Shares to the total issued Shares at the end of each month during the Review Period:

Month Monthly trading volume of the Shares (Shares) Number of trading days in the month (days) Average daily trading volume of the Shares in the month (Shares) (Note 1) Approximate percentage of average daily trading volume of the Shares to total number of Shares (Note 2)
From 6 March 2025 to 31 March 2025 30,641,781 18 1,702,321.17 0.38%
April 2025 3,586,897 19 188,784.05 0.04%
May 2025 11,168,404 20 558,420.20 0.12%
June 2025 1,884,637 21 89,744.62 0.02%
July 2025 7,912,765 22 359,671.14 0.08%
August 2025 6,831,818 21 325,324.67 0.07%
September 2025 9,700,052 22 440,911.45 0.10%
October 2025 24,170,760 20 1,208,538.00 0.27%
November 2025 3,482,903 20 174,145.15 0.04%
December 2025 1,365,404 21 65,019.24 0.01%
January 2026 15,068,352 21 717,540.57 0.16%
February 2026 86,152,937 17 5,067,819.82 0.95%
From 1 March 2026 to 5 March 2026 3,469,248 4 867,312.00 0.16%

Source: Website of the Stock Exchange

Notes:

  1. Average daily trading volume is calculated by dividing the total trading volume for the month/period by the number of trading days in the respective month/ period.
  2. Calculation is based on the average daily trading volume of Shares divided by the total issued Shares of the Company at the end of each respective month.

During the Review Period, the monthly trading volume of the Shares varied significantly. It ranged from a low of 1,365,404 Shares traded in December 2025 to a peak of 86,152,937 Shares traded in February 2026. This represents approximately 0.01% of the total issued Shares for the lowest volume and approximately 0.95% for the highest volume.


LETTER FROM THE BOARD

Based on the observations presented, the Directors have determined that the low trading volume may pose challenges for Shareholders in selling their Shares on time and at a more favourable price. Furthermore, the Company may encounter difficulties in raising equity funds from external parties without necessitating a discount to the current Share price. As a result, the Directors believe that the limited liquidity of the Shares observed during the Review Period suggests the potential for a discount to the current Share price to encourage the Places to subscribe the Placing Shares.

(iii) the Directors identified an exhaustive list of 9 cases of placing under specific mandate conducted by companies listed on the Stock Exchange (the “Comparables”) using information available from the Stock Exchange’s website, which was done on a best-effort basis. The criteria for selecting these Comparables were as follows:

(a) the companies must be listed on the Stock Exchange; and
(b) the proposed placing under specific mandate must have been announced during the Review Period.

The Directors believe that these Comparables serve as a reliable reference for recent placing under specific mandate because a sufficient number of cases occurred within this timeframe, resulting in a reasonable sample size. The table below presents the findings from this analysis.

LETTER FROM THE BOARD

Date of initial announcement Company name Stock code Premium/(Discount) of placing price over/to the closing share price on the last trading day Premium/ (Discount) of placing price over/to the closing price for the five consecutive trading days immediately preceding the date of the placing agreement (last trading day) Market Capitalisation (HK$ million) Fundraising Scale (HK$ million)

05/03/2026 Synertone Communication Corporation 1613 (20.00%) (20.00%) 72.34 108.00

The table above presents a detailed overview of the placing prices of the Comparables in relation to their respective closing prices on or before the dates of the last trading day. These prices varied, showing a discount of approximately 24.53% to a discount of approximately 8.57%.

In further examining the placing prices in comparison to the average closing prices over the five trading days before the date of the last trading day, the Directors found that the results showed a comparable range, with the prices varying from a discount of approximately 28.57% to a discount of approximately 9.09%.

As a result, the discount of approximately 20.00% to the closing Share price of HK$0.135 per Share as quoted on the Stock Exchange on the date of the Placing Agreement, and the discount of approximately 20.00% to the average closing Share price of HK$0.135 per Share for the five consecutive trading days immediately preceding the date of the Placing Agreement, fall within the established range of the Comparables.


LETTER FROM THE BOARD

After a thorough review of the Comparables, the Directors determined that the Placing Price was set within an acceptable range. However, although the Placing Price is lower than all closing Share Prices during the Review Period, and the discount used to determine the Placing Price is almost equal to the maximum discount observed among the Comparables, the Directors considered the following additional factors to ensure that the Placing Price remains fair and reasonable:

(i) the observed high volatility in the closing prices of the Shares, coupled with the limited liquidity during the Review Period, indicates the potential for a discount to the Placing Price. This adjustment could serve to encourage participations from the Places in the Placing; and
(ii) the insights provided in the section titled "REASONS FOR THE PLACING AND USE OF PROCEEDS" outlined in this letter.

Considering the factors mentioned above, the Directors believe that the benefits associated with them outweigh the discount applied to the Placing Price. To strike a balance between the Company's cash flow needs and the interests of its Shareholders, the Company has set a discount to encourage participations in the Placing. As a result, the Directors consider the discount to be fair and reasonable.

Taking into account the estimated expenses for the Placing of approximately HK$1,400,000, comprising fees, costs, charges, and other related expenses, and assuming the successful placement of all 1,000,000,000 Placing Shares, the net price of each Placing Share will be approximately HK$0.107 per Placing Share.

Placing fee

In consideration of the services provided by the Placing Agent in relation to the Placing, and provided that the Completion occurs, the Company shall pay the Placing Agent a commission of one (1)% of the aggregate Placing Price for the Placing Shares which the Placing Agent is authorised to deduct from the payment to be made by it to the Company at Completion.

Assuming all 1,000,000,000 Placing Shares are placed, the maximum commission payable by the Company to the Placing Agent will be HK$1,080,000.

The placing commission under the Placing Agreement was determined after arm's length negotiations between the Company and the Placing Agent with reference to the prevailing market conditions.

Conditions Precedent

The obligations of the Placing Agent and the obligations of the Company are upon the fulfillment of the following conditions:

(a) the grant by the Stock Exchange of the listing of, and permission to deal in, all of the Placing Shares being obtained and not subsequently revoked;


LETTER FROM THE BOARD

(c) all necessary consents and approvals to be obtained on the part of the Placing Agent and the Company in respect of the Placing Agreement and the transactions contemplated thereunder having been obtained; and

(d) the Placing Agreement not being terminated pursuant to the terms thereof.

The above Conditions Precedent cannot be waived by any party.

Each of the Company and the Placing Agent shall use their respective best endeavours to procure the satisfaction of the Conditions Precedent on 30 June 2026 (or such other date as the parties hereto may agree in writing) ("Long Stop Date"), but if the Conditions Precedent or any of them shall not be so satisfied by the Long Stop Date, all obligations of the Placing Agent and of the Company thereunder shall cease and determine and none of the parties thereto shall have any claim against the other in relation thereto (save in respect of any antecedent breach of any obligation under the Placing Agreement).

(1) there is any change in national, international, financial, exchange control, political, or economic conditions in Hong Kong which, in the reasonable opinion of the Placing Agent would be materially adverse in the consummation of the Placing; or

(2) there is any breach of the warranties, representations, and undertakings given by the Company in the Placing Agreement and such breach is considered by the Placing Agent on reasonable grounds to be material in the context of the Placing; or


LETTER FROM THE BOARD

(5) any statement contained in the Previous Announcements has become or been discovered to be untrue, incorrect, or misleading in any material respect which, in the reasonable opinion of the Placing Agent, would be materially adverse in the consummation of the Placing.

The Board would like to refer to the Company's announcement dated 13 February 2026, regarding the outcome of the Rights Issue. The Board emphasises that the Company secured approximately HK$10.8 million in net proceeds from the Rights Issue, which will be used for general working capital. However, it is important to note that the Rights Issue experienced undersubscription, and the Unsubscribed Rights Shares were not fully placed. Consequently, the Company was unable to raise the anticipated funds needed to support its business expansion initiatives.

In response to this situation, the Directors have engaged in discussions with the Placing Agent. Following a thorough review of prevailing market conditions, the Group's financial position, and its funding needs for business development, the Directors have decided to proceed with the Placing. This decision includes an adjustment to the Placing Price to attract potential investors and secure the necessary funds for the Company's expansion plans, as outlined in the Prospectus, regarding the Building Intelligence Business.

As disclosed in the Prospectus, the Group plans to relocate production from China to Australia. Currently, production occurs in China with all components sourced from Chinese suppliers, resulting in products labeled "Made in China." However, geopolitical tensions and market access restrictions have created challenges for global sales. To overcome these issues, the Company will leverage its industry expertise and established supply chains to set up production facilities in Australia, ensuring international standards are met.

The Board emphasises that the existing business model will remain largely unchanged, relying on the knowledge gained during operations. The Group has secured a memorandum of understanding with its Chinese supplier for continued support and has collaborated with three Australian companies that will assist with sales and exports.

The Company plans to allocate approximately HK$89.3 million from Net Proceeds to develop its Building Intelligence Business, with funds distributed as follows:

(i) approximately HK$61.9 million for leasing and setting up a new production plant in Australia;

(ii) approximately HK$24.5 million for recruiting qualified personnel, including factory workers and engineers; and

(iii) approximately HK$2.9 million for expanding the sales and marketing network.

Due to the postponement of development caused by funding shortages, a suitable site for the new facility is expected to be secured by the second quarter of 2026, with production set to commence in the fourth quarter. The funding is projected to be fully utilized within 12 months, and the plan aims for product launch and sales by first half of 2027.

LETTER FROM THE BOARD

General working capital and general corporate purposes

After reviewing the above business expansion plan and considering the potential increase in operating expenses, as well as the Group’s financial information for the six months ended 30 September 2025, the Directors have decided to allocate HK$17.3 million from the Net Proceeds to cover these operating costs, which includes approximately HK$10.4 million for employee salaries and related expenses, around HK$1.3 million for legal and professional fees, HK$2.4 million for rental payments, and approximately HK$3.2 million for other administrative costs. It is anticipated that this budget will be fully utilised within 12 months following Completion.

Other fund-raising alternatives

Following a thorough evaluation of the Rights Issue, the Board has carefully considered various alternative fundraising methods, including the subscription of new shares, a rights issue, an open offer, bank borrowing, and convertible bonds. After this assessment, the Board has concluded that a Placing represents the most suitable approach for raising additional capital for several key reasons:

(i) the timing required for placement is generally less than that required for a rights issue or an open offer. In particular, the Board has determined that executing a rights issue or an open offer will take at least two to three months to complete. This time frame is attributed to several important processes, which include but are not limited to (a) preparing and obtaining approval for the circular and listing document as required by the Listing Rules; (b) organising a shareholders’ meeting to obtain the necessary shareholders’ approvals; (c) facilitating qualifying shareholders participation in the rights issue or open offer; or/and (d) placing any unsubscribed rights shares if the rights issue or open offer is conducted on a non-underwritten basis. As a result, it is evident that the procedures for rights issues or open offers are more time-consuming and resource-intensive than those for a placement. In addition, the financing expenses associated with rights issues or open offers, such as underwriting commission or/and placing commission, prospectus preparation costs, and a range of professional service fees (including legal and financial advisory fees), would likely be incurred, thereby further increasing the overall cost and complexity of such transactions;

(ii) the Company faces challenges in securing underwriters and/or potential investors, primarily due to the volatility in the closing Share price and low trading volumes, which may create difficulties for investors wishing to sell their shares promptly and at favorable prices;

(iii) engaging in debt financing may result in increased financial costs and a higher level of gearing, which could place additional financial pressure on the Group;

(iv) debt financing typically requires the pledge of assets or securities, which may limit the Group’s ability to manage and deploy its assets effectively, ultimately reducing operational flexibility; and

(v) the processes associated with debt financing or approaching potential investors for subscriptions often entail extensive due diligence and negotiations, which can render it uncertain and time-consuming to secure financing at acceptable costs or under favorable terms and conditions.

In light of these considerations, the Board believes that pursuing a Placing is the most advantageous course of action for the Company.

Additionally, none of the Placees will be obliged to make a mandatory general offer to other Shareholders under the Takeovers Code.

The Company and the Placing Agent will take all appropriate measures to ensure that sufficient public float is maintained in compliance with the Public Float Requirements during the Placing and upon the Completion. If the Placing results in a public float that could not be maintained, the Company and/or the Placing Agent will take necessary action to place down the Shares such that sufficient public float could be maintained in compliance with the Public Float Requirements.


LETTER FROM THE BOARD

EQUITY FUND-RAISING ACTIVITIES OF THE COMPANY IN THE PAST 12 MONTHS

The Company has conducted the following equity fundraising activities in the past 12 months immediately prior to the Latest Practicable Date:

Date of relevant announcements, circular, and prospectus Event Net proceeds Intended use of proceeds Actual use of proceeds as at the Latest Practicable Date
30 December 2025, 22
January 2026, and 13
February 2026 Rights Issue HK$10.8 million For general working capital and general corporate purposes Approximately HK$612,000

The Directors would like to clarify the Rights Issue detailed in the Prospectus. Initially, the maximum anticipated net proceeds were estimated at approximately HK$119.3 million. According to the original budget, approximately 74.9% of the net proceeds, totaling approximately HK$89.3 million, was intended to support the Group's expansion plan, while the remaining approximately 25.1%, totaling approximately HK$30.0 million, was designated for general working capital and corporate purposes.

The Prospectus also stated that in the event of an undersubscription of the Rights Issue, net proceeds would be allocated proportionately among the specified uses. Unfortunately, due to undersubscription, the actual net proceeds from the Rights Issue were reduced to approximately HK$10.8 million. As a result of this shortfall, the Directors determined that the Company would be unable to proceed with the aforementioned planned expansion unless additional financing is secured.

As a result, it was decided that the actual net proceeds from the Rights Issue will be allocated to general working capital and corporate purposes. The Company remains committed to exploring alternative financing options to support its expansion objectives. In light of this, on 13 February 2026, the Company formally announced the modification of the intended use of the net proceeds from the Rights Issue. For further details, please refer to the Company's announcement dated 13 February 2026.
