SDI Corporation 2021 Business Report

Dear Sir/Madam:

SDI has successfully completed operation of 2021 with the Company’s prevention and control of pandemic, and all colleagues’ joint efforts. SDI Group continues to increase production capacity, reduce wearing down and speed up the mass production of new products to develop electronic and stationary business. We also provide for the customer’s requirements on increased orders, the quality, and the delivery date to the satisfaction of customers through more frequent contacts with the supplier and customers through carefully-planned video sessions during the pandemic period.

In 2021, the global economy continued to be affected by geopolitical disputes and variant viruses and faced with the impact of industrial disruptions and freight delays. Also, due to the increasing amount of money circulating in the economy caused by QE and low interest rates undertaken by the governments of many countries in recent years, as well as the global efforts to promote energy conservation and carbon emission reduction, inflation has risen at a substantially faster pace, and the CPI in numerous countries has reached a record high in decades. The relatively slow growth of the general economy has dealt yet another severe blow to not only people's consumption patterns but also the information and communication industry. On the other hand, as investments in and demands for emerging energy management technologies and xEVs started growing at an exponential rate, the semiconductor industry have been thriving and investors flourishing. SDI’s electronic business group mainly supplies for IDM clients worldwide. The sales performance benefited from the above growing demands for mid-end and high-end energy management and xEVs products, so it has generated substantial revenues and profits continuously. SDI’s electronic business group continues to collaborate with major clients to develop and mass-produce new power management and power application products to create more added value. During the period that demands were reduced in 2020, the electronic business group implemented smart manufacturing, efficiency optimization, diverse procurement, and application of information technologies in order to fulfill the requirements for high-level quality and demands for high-end automotive and industrial products. Moreover, the electronic business group has secured supplies of materials and reduced costs in order to mitigate the impact of adverse circumstances on business operations, such as material shortages, high copper prices, and high exchange rates. For the stationery business, to ease the impact of increased costs resulting from inflation and drops in demands because of the pandemic, it has utilized creative

~3~

marketing strategies including marketing campaigns and development of new products to create consumer demand. Last but not least, SDI’s affiliated companies have also generated considerable revenues and profits; TEC Brite Technology has cultivated niche clients, increased market share, and improved production capacity; Chao Shin Metal has benefited from rising steel prices and business relationships with new clients; the re-invested Jiangsu Plant has continued to improve production capacity and efficiency and to satisfy surging demands for developing the third-generation semiconductors in China.

In total, SDI’s revenue in 2021 is NT$ 8.247 billion, with a increase of 32%. The group’s consolidated revenue is NT$ 11.152 billion, with a increase of nearly 32%. Net profit of this period is NT$852 million, and earning per share is NT$4.68, a record high.

The applications of and demands for automobiles, xEVs, servers, and 5G increased significantly in 2021, and the total global semiconductor sales reached US$553 billion, representing growth of 26%. The World Semiconductor Trade Statistics (WSTS) has released a forecast that the global semiconductor market would grow by 8.8% to more than US$600 billion in 2022, where the output value of discrete devices, analog ICs, and memories would grow by 6.2% to 8.8%, and sensors and logic ICs would also have double-digit growth. SDI’s electronic business group has not only diversified to supply the above industrial needs but also combined R&D and manufacturing to collaborate with clients in developing GaN and SiC product applications. By speeding up mass production and improving production processes, the electronic business group has worked diligently to increase added value and remained a leader in the industry for its development and innovation efforts. With respect to the hardware and stationery business, we have continued to expand production capacity in Taiwan and develop more OBM products to elevate competitiveness and rates of profit.

‑ With the roll out of vaccines and access to oral antiviral treatments for COVID 19, borders are reopening and bottlenecks in global supply chains are being addressed and resolved in 2022, which fuels optimism about the recovery of the global economy and eases the stress in manufacturing. At the same time, as the demand for new energy sources started surging after the economy began recovering, inflation will linger at high levels for longer. The advances in power semiconductor technology driven by the developments of and demands for automobiles, industrial controls, and green energy have provided customers with a wide array of benefits. With smart factories and efficient production lines in place, SDI Group is striving to expand manufacturing capacity and process efficiency in order to enhance business value and fulfill customer needs. We hope our shareholders can continue to support and assist us. We believe we can grow our Group's business and ensure its success with our stable and continuously innovative development and acceptance to challenge and innovation.

If the aforementioned two postponements still fail to meet the quorum, but the number of shares that represent more than one-third of the total number of issued shares are present, tentative resolutions may be resolved pursuant to Article 175-1 of the Company Act, and each shareholder will be notified of the tentative resolutions, and another shareholders' meeting will be convened within one month.

If, prior to conclusion of the meeting, the attending shareholders represent more than half of the total number of issued shares, the chairperson may resubmit the tentative resolutions for a vote by the shareholders' meeting pursuant to Article 174 of the Company Act.

Article 10 If a shareholders’ meeting is convened by the Board of Directors, the meeting agenda shall be set by the Board of Directors. The relevant proposals (including extempore motions and amendments to the original proposals) shall be voted one by one. The meeting shall proceed in the order set by the agenda, which may not be changed without a resolution of the shareholders’ meeting. The provisions of the preceding paragraph apply mutatis mutandis to a shareholders' meeting convened by a party with the power to convene that is not the Board of Directors.

The chairperson may not declare the meeting adjourned prior to completion of deliberation on the meeting agenda set out in the preceding two paragraphs (including extempore motions), except upon a resolution adopted by the shareholders' meeting. If the chairperson declares the meeting adjourned in violation of the rules of procedure, other members of the Board of Directors shall promptly assist the shareholders present in electing a new chairperson in accordance with the statutory procedures. The meeting shall continue after a chairperson is elected with the approval of more than half the voting rights represented by the shareholders present. The chair shall allow ample opportunity during the meeting for explanation and discussion of proposals and of amendments or extraordinary motions put forward by the shareholders; where

~ 54~

		the chairperson believes an issue has been discussed in the meeting up to the level for voting, the
		chairperson may announce discontinuance of the discussion process and bring that issue to a vote,
		and arrange a sufficient voting time.
Article	11	A shareholder wishing to speak in a shareholders meeting shall first fill out a speaker's slip,
		specifying therein the essentials of his speech, his or her shareholder account number (or
		attendance card number) and the account name, and the chairperson shall determine his or her
		order of giving a speech.
		A shareholder who has submitted a speaker's slip but does not actually speak shall be deemed to
		have not spoken. If the contents of speech are inconsistent with the contents of speaker's slip, the
		contents of speech shall prevail.
		Except with the consent of the chairperson, a shareholder may not speak more than twice on the
		same proposal, and a single speech may not exceed five minutes. If the shareholder's speech
		violates the rules or exceeds the scope of the issue under discussion, the chairperson may
		terminate the speech.
		When a shareholder attends the shareholders' meeting, other shareholders may not speak or
		interrupt unless they have sought and obtained the consent of the chairperson and the shareholder
		that has the floor. The chairperson shall stop any violation.
		When a juristic person shareholder appoints two or more representatives to attend a shareholders'
		meeting, only one of the representatives may speak on the same proposal.
		After an attending shareholder has spoken, the chairperson may respond in person or direct
		relevant personnel to respond.
Article	12	Voting at a shareholders' meeting shall be calculated based the number of shares.
		For the resolutions of the shareholders' meeting, the number of shares of the non-voting
		shareholders is not included in the total number of issued shares.
		A shareholder who has a personal interest in the matter under discussion at a meeting, which may
		impair the interest of the Company, shall not vote nor exercise the voting right on behalf of
		another shareholder.
		The number of shares with voting rights that cannot be exercised in the preceding Paragraph shall
		not be counted as part of the voting rights represented by attending shareholders.
		Except for trust enterprises or stock agencies approved by the competent authority, when a person
		who acts as the proxy for two or more shareholders, the number of voting power represented by
		him/her shall not exceed three percent of the total number of voting shares of the company,
		otherwise, the portion of excessive voting power shall not be counted.
Article	13	A shareholder shall be entitled to one vote for each share held, except when the shares are
		restricted or deemed non-voting shares under Paragraph 2, Article 179 of the Company Act.
		When the Company convenes a shareholders' meeting, shareholders may exercise their voting
		power in writing or by way of electronic transmission; the method of exercising their voting
		power shall be describes in the shareholders' meeting notice. A shareholder who exercises
		his/her/its voting power at a shareholders meeting in writing or by way of electronic transmission
		shall be deemed to have attended the said shareholders’ meeting in person. However, he or she
		shall be deemed to have waived his or her voting power in respective of any extempore motion(s)
		and/or the amendment(s) to the contents of the original proposal(s) at the said shareholders’
		meeting. Therefore, it is advisable that the Company avoids proposing any extempore motion(s)
		and amendment(s) to the contents of the original proposal(s).
		In case a shareholder elects to exercise his/her/its voting power in writing or by way of electronic
		transmission, his or her declaration of intention shall be served to the company two days prior to
		the scheduled meeting date of the shareholders' meeting, whereas if two or more declarations of
		the same intention are served to the company, the first declaration of such intention received shall
		prevail. However, the foregoing does not apply where an explicit statement to revoke the previous
		declaration is made in the declaration which comes later.
		In case a shareholder who has exercised his/her/its voting power in writing or by way of
		electronic transmission intends to attend the shareholders' meeting in person, he or she shall, two

~ 55~

		days prior to the meeting date of the scheduled shareholders' meeting and in the same manner
		previously used in exercising his or her voting power, serve a separate declaration of intention to
		rescind his or her previous declaration of intention made in exercising the voting power under the
		preceding section. In the absence of a timely rescission of the previous declaration of intention,
		the voting power exercised in writing or by way of electronic transmission shall prevail. In case a
		shareholder has exercised his or her voting power in writing or by way of electronic transmission,
		and has also authorized a proxy to attend the shareholders' meeting in his or her behalf, then the
		voting power exercised by the authorized proxy for the said shareholder shall prevail.
		Resolutions at a shareholders' meeting shall, unless otherwise provided for in the Company Act
		and the Company's Articles of Incorporation, be adopted by a majority vote of the shareholders
		present, who represent more than one-half of the total number of voting shares. At the time of
		voting, the shareholders shall vote on the proposals one by one after the chairperson or its
		designee announces the total number of voting power of the present shareholders, and the
		shareholders’ consent, objection and waiver shall be entered into the Market Observation Post
		System on the same day after the shareholders’ meeting is convened.
		When there is an amendment or an alternative to a proposal, the chairperson shall present the
		amended or alternative proposal together with the original proposal and decide the order in which
		they will be put to a vote. When any one among them is passed, the other proposals will then be
		deemed rejected, and no further voting shall be required.
		Scrutineers and vote counting personnel for the voting on a proposal shall be appointed by the
		chairperson, provided that all scrutineers shall be shareholders of the Company.
		The recording procedure of issues of shareholder meetings shall be processing publicly in
		shareholder meetings and the results including statistical weights shall be reported on the spot and
		shall be recorded into the minutes of the meeting.
Article	14	The election of directors at a shareholders' meeting shall be held in accordance with the
		applicable election and appointment rules of the Company, and the election results shall be
		announced on-site immediately, including the names of those elected as directors and the numbers
		of voting rights with which they were elected.
		The ballots for the election under the preceding paragraph shall be sealed with the signatures of
		the scrutineers and kept in proper custody for at least one year. If, however, a shareholder files a
		lawsuit based on Article 189 of the Company Act, the recordings shall be retained until the
		conclusion of the litigation.
Article	15	Resolutions adopted at a shareholders' meeting shall be recorded in the minutes of the meeting,
		which shall be affixed with the signature or seal of the chairman of the meeting and shall be
		distributed to all shareholders of the company within twenty days after the close of the meeting.
		The preparation and distribution of the minutes of shareholders' meeting may be effected by
		means of electronic transmission.
		The Company may distribute the meeting minutes as described in the preceding paragraph by
		entering the same to the Market Observation Post System for public announcement.
		The minutes of shareholders’ meeting shall record the date and place of the meeting, the name of
		the chairperson, the method of adopting resolutions, and a summary of the essential points of the
		proceedings and the results of the meeting. When a director is election, the number of votes
		casted to each candidate shall be disclosed. The meeting minutes shall be retained for as long as
		the Company is in existence.
Article	16	On the day of a shareholders' meeting, the Company shall compile in the prescribed format a
		statistical statement of the number of shares obtained by solicitors through solicitation and the
		number of shares represented by proxies, and shall make an express disclosure of the same at the
		place of the shareholders' meeting.
		If matters put to a resolution at a shareholders' meeting constitute material information under
		applicable laws or regulations or under Taiwan Stock Exchange Corporation regulations, the
		Company shall upload the content of such resolution to the MOPS within the prescribed time
		period.

The chairperson may direct the inspectors or security personnel to help maintain order at the meeting place. The pickets or security personnel shall wear armbands with the word "Picket" when maintaining order.
At the place of a shareholders' meeting, if a shareholder attempts to speak through any device other than the public address equipment set up by the Company, the chairperson may stop the shareholder from so doing.
If the shareholder violates the rules of procedures and defies the chairperson's instruction, and obstructs the proceedings and refuses to stop, the chairperson may direct the pickets or security personnel to escort the shareholder out of the venue.
Article 18 When a meeting is in progress, the chairperson may announce a break based on time considerations. If a force majeure event occurs, the chairperson may rule the meeting temporarily suspended and announce a time when, in view of the circumstances, the meeting will be resumed. Before the completion of agendas (including extraordinary motions) of the shareholders' meeting, if the meeting venue is not available for continued use, the shareholders' meeting may decide to seek a new venue to resume the meeting.
The shareholders' meeting may, in accordance with the provisions of Article 182 of the Company Act, decide to postpone or resume the assembly within five days.
Article 19 The Rules, along with any amendments hereto, shall be implemented after adoption by shareholders' meetings.
