Hong Kong Exchanges and Clearing Limited, The Stock Exchange of Hong Kong Limited (the “Hong Kong Stock
Exchange ”) and Hong Kong Securities Clearing Company Limited ( “HKSCC ”) take no responsibility for the contents
of this announcement, make no representation as to its accuracy or completeness and expressly disclaim any liability
whatsoever for any loss howsoever arising from or in reliance upon the whole or any part of the contents of this
announcement.
Unless otherwise defined in this announcement, capitalized terms used herein shall have the same meanings as those
defined in the prospectus dated June 9, 2026 (the “Prospectus ”) issued by SENASIC Electronics Technology Co., Ltd.
(琻Ҧ (Ϫᘽ)ʮ̡ ) (the “Company ”).
This announcement is for information purposes only and does not constitute an offer or an invitation to induce an offer
by any person to acquire, purchase or subscribe for any of the securities of the Company. This announcement is not a
prospectus. Potential investors should read the Prospectus for detailed information about the Global Offering described
below before deciding whether or not to invest in the Offer Shares. Any investment decision in relation to the Offer
Shares should be taken solely in reliance on the information provided in the Prospectus.
This announcement does not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale
of Offer Shares in any jurisdiction in which such offer, solicitation or sales would be unlawful. This announcement is
not for release, publication or distribution, directly or indirectly, in or into the United States or any other jurisdiction
where such distribution is prohibited by law, nor is this announcement an offer for sale or solicitation to purchase or
subscribe for securities in the United States or any other jurisdictions. The Offer Shares have not been, and will not
be, registered under the United States Securities Act of 1933, as amended from time to time (the “U.S. Securities
Act”), or any applicable state securities laws, and may not be offered, sold, pledged or transferred within the United
States or to, or for the account or benefit of, U.S. persons (as defined in Regulation S under the U.S. Securities Act
(the “Regulation S ”)) except in transactions exempt from, or not subject to, the registration requirements of the
U.S. Securities Act. The Offer Shares are being offered and sold outside the United States in offshore transactions in
accordance with Regulation S. There will be no public offering of the Offer Shares in the United States.
In connection with the Global Offering, China International Capital Corporation Hong Kong Securities Limited as
stabilising manager (the “Stabilisation Manager ”) (or its affiliates or any person acting for it), on behalf of the
Underwriters, to the extent permitted by the applicable laws and regulatory requirements of Hong Kong or elsewhere,
may over-allocate or effect transactions with a view to stabilising or supporting the market price of the Shares at such
price, in such amounts and in such manners as the Stabilising Manager, its affiliates or any person acting for it may
determine and at a level higher than that which might otherwise prevail for a limited period after the Listing Date.
However, there is no obligation on the Stabilising Manager (or its affiliates or any person acting for it) to conduct
any such stabilising action. Such stabilising action, if taken, (a) will be conducted at the absolute discretion of the
Stabilisation Manager (or its affiliates or any person acting for it) and in what the Stabilising Manager reasonably
regards as the best interest of our Company, (b) may be discontinued at any time and (c) is required to be brought to
an end within 30 days of the last day for lodging applications under the Hong Kong Public Offering (which is Sunday,
July 12, 2026). Such stabilising action, if taken, may be effected in all jurisdictions where it is permissible to do so,
in each case in compliance with all applicable laws, rules and regulatory requirements, including the Securities and
Futures (Price Stabilizing) Rules (Chapter 571W of the Laws of Hong Kong), as amended, made under the Securities
and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).
The Hong Kong Offer Shares will be offered to the public in Hong Kong subject to term and conditions set out in
the Prospectus. The Hong Kong Offer Shares will not be offered to any person who is outside Hong Kong and/or not
resident in Hong Kong.
Potential investors should be aware that no stabilising action can be taken to support the price of the Shares for longer
than the stabilisation period, which will begin on the Listing Date, and is expected to expire on the 30th day after the
last day for lodging applications under the Hong Kong Public Offering (which is Sunday, July 12, 2026). After this
date, when no further stabilising action may be taken, demand for the Shares, and therefore the price of the Shares,
could fall.
Potential investors of the Offer Shares should note that the Overall Coordinators (for themselves and on behalf of
the Hong Kong Underwriters) shall be entitled to terminate their obligations under the Hong Kong Underwriting
Agreement with immediate effect upon the occurrence of any of the events set out in the paragraph headed
“Underwriting – Underwriting Arrangements and Expenses – Hong Kong Public Offering – Grounds for Termination ”
in the Prospectus at any time prior to 8:00 a.m. (Hong Kong time) on the Listing Date (which is currently expected to
be on or about Wednesday, June 17, 2026).

APPLICATION FOR LISTING ON THE HONG KONG STOCK EXCHANGE
We have applied to the listing committee of the Hong Kong Stock Exchange for the granting of
the listing of, and permission to deal in, our Shares in issue and to be issued pursuant to the Global
Offering.
STRUCTURE OF THE GLOBAL OFFERING
The Global Offering comprises:
(1) the Hong Kong Public Offering of initially 5,340,800 H Shares (subject to reallocation) in
Hong Kong, representing approximately 10% of the total number of Offer Shares initially
available under the Global Offering; and
(2) the International Offering of initially 48,066,200 H Shares (subject to reallocation and the
Over-allotment Option), representing approximately 90% of the total number of Offer Shares
initially available under the Global Offering.
The allocation of the Offer Shares between the Hong Kong Public Offering and the International
Offering will be subject to reallocation as described in the section headed “Structure of the Global
Offering ” in the Prospectus.
In particular, subject to the requirements under Practice Note 18 of the Listing Rules and Chapter
4.14 of the Guide for New Listing Applicants issued by the Hong Kong Stock Exchange, the Joint
Sponsor-OCs (for themselves and on behalf of the Underwriters) may, at their sole discretion,
reallocate Offer Shares from the International Offering to the Hong Kong Public Offering to satisfy
valid applications under the Hong Kong Public Offering. In accordance with Chapter 4.14 of the
Guide for New Listing Applicants issued by the Hong Kong Stock Exchange, if such reallocation is
done as described in the section headed “Structure of the Global Offering – The Hong Kong Public
Offering – Reallocation ” in the Prospectus, the maximum total number of Offer Shares that may
be reallocated to the Hong Kong Public Offering will be 2,670,200 Offer Shares, so that the total
number of Offer Shares for subscription under the Hong Kong Public Offering will increase up to
8,011,000 Offer Shares, representing approximately 15% of the number of Offer Shares initially
available under the Global Offering.


--- page 6 ---

In connection with the Global Offering, we may grant the Over-allotment Option to the
International Underwriters, exercisable by the Joint Sponsor-OCs (for themselves and on behalf of
the International Underwriters).
Pursuant to the Over-allotment Option (if granted), the International Underwriters will have the
right, exercisable by the Joint Sponsor-OCs (for themselves and on behalf of the International
Underwriters) at any time from the date of the Listing Date until 30 days from the last day for the
lodging of applications under the Hong Kong Public Offering, to require our Company to issue
up to an aggregate of 8,011,000 additional H Shares, representing not more than 15% of the total
number of Offer Shares initially available under the Global Offering, at the Offer Price under the
International Offering to, among others, cover over-allocations in the International Offering, if any.
If the Over-allotment Option is exercised in full, the additional Offer Shares to be issued pursuant
thereto will represent approximately 2.07% of the enlarged issued share capital of the Company
immediately following the completion of the Global Offering and the exercise of the Overallotment
Option. If the Over-allotment Option is exercised, an announcement will be made.
PRICING
The Offer Price will be HK$18.36 per Offer Share unless otherwise announced, as further
explained below. Applicants under the Hong Kong Public Offering may be required to pay, on
application (subject to application channels), the Offer Price of HK$18.36 per Offer Share plus
brokerage of 1.0%, SFC transaction levy of 0.0027%, Hong Kong Stock Exchange trading fee of
0.00565% and AFRC transaction levy of 0.00015%, amounting to a total of HK$3,709.04 for one
board lot of 200 H Shares. Further details are set out in the section headed “How to Apply for
Hong Kong Offer Shares ” in the Prospectus.
