S.J. Cheng, Chairman and President

Thank you, GS. We appreciate everyone joining our call today.

We delivered strong fourth quarter results, driven by improving demand for high-value memory solutions, particularly in data center and AI-related applications. This sustained strong demand more than offset continued softness in certain consumer end markets. Both the quarter and full year 2025 results reflect a better mix, and ongoing pricing discipline, which supports our revenue momentum and expanding profitability. We continue to execute from a position of technology and scale leadership, while maintaining a highly disciplined approach to capital spending. We are prioritizing critical growth programs and customer commitments while protecting the strength of our balance sheet. Our focus remains clear: deepen strategic customer relationships, gain share in structurally growing markets, expand margins, and build durable long-term shareholder value.

In terms of highlights….

• We achieved a record quarterly high revenue since Q3 2022, with Q4 revenue up over 6% compared to Q3, and up nearly 21% on a year-over-year basis. 2025 annual revenue increased 5.5% compared to 2024.

• Q4 Gross Margin increased 190 basis points quarter over quarter to 14.3%. This strength was driven by favorable product mix and assembly UT level.

• Q4 Net Earnings were NT$ 0.72, and with accumulated Net Earnings for 2025 were NT$ 0.70.

In terms of the details, our overall utilization rate was 65% in Q4, with an improvement in Memory products led by strong demand in support of AI, computing and datacenters.

As of January 31, 2026 the Company's outstanding ADS number was approximately 3.5 million units, which represents around 9.9% of the Company's outstanding common shares.

That concludes the financial review. I will now turn the call back to our Chairman Mr. S.J. Cheng for our outlook. Please go ahead, sir.

SJ Cheng, Chairman and President

Thank you, Silvia.

As you can see both Q4 and the full year 2025 were very strong for ChipMOS. We do not expect this demand to strength to let up given visibility we have with customers, solid memory momentum and positive comments across the semiconductor industry this earnings season. Our business momentum is expected remain stable and results is optimistic compared to 2025. As is typical for our business, Q1 can be a little slower with the fewer working days. We expect normal seasonal patterns with the second half coming in stronger than the first half. In the meantime, we will manage our own capacity and work with customers to ensure they are properly supported.

Adding to our confidence, solid memory products momentum growth driven by customers' re-stocking is expected to help improve related UT levels of assembly and test. DRAM momentum is also expected to maintain solid driven by customers' strong demand for DDR4 and DDR5 release to production. Flash momentum is slightly slow down, impacted by customers' stock adjustments. Therefore, we expect memory momentum will be better than DDIC in Q1 and coming quarters. Meanwhile, to reflect the

continued rise in material costs, especially gold, we plan to increase memory products OSAT price again since Q1 to offset cost increases, and maintain profitability.

In our DDIC product business, the momentum is expected to be remain soft in Q1, which is inline with the broader industry. However, automotive panel and wearable product momentum is relatively stable compared to other DDIC products. In addition, regarding mixed-signal products, momentum is expected to increase this year, driven by the benefits of product diversification.

Regarding to 2026 CapEx, except memory product bottleneck capacity expansion and automation, we plan invest in capacity expansion to meet customers' future demand for new product projects and increased volumes. In the meantime, we will also continue our cost reductions, quality improvement and operating strength actions to further improve profit and maintain business growth momentum and competition advantage. This is a fundamental practice for us that is ongoing and never done. We continue to execute from a position of technology and scale leadership, while maintaining a highly disciplined approach to capital spending.

Importantly, we continue to prioritize returning capital to shareholders as part of our overall shareholder-friendly capital allocation plan. I am pleased to report that pending shareholder approval at our May AGM, we will distribute NT$ 1.23 per common share by Capital Surplus. As I commented at the start of today's call, we are prioritizing critical growth programs and customer commitments while protecting the strength of our balance sheet. Our focus remains clear: deepen strategic customer relationships, gain share in structurally growing markets, expand margins, and build durable long-term shareholder value.

Finally, we would like to announce again, we have decided to move to semiannual conference calls from quarterly conference calls, with the next call to be held for the first 6 months results of 2026. Financial reporting of operation results per regulation will remain reviewed by our Accountant quarterly, approved by our Board and then published. Although the timing of our calls is changing, we will remain very accessible to investors and analysts. We plan to continue participating in investment forums and conferences, and other various investor and analyst meetings to enhance communication with investors and ensure a more complete understanding of our operating environment and financial results.

Operator, that concludes our formal remarks, we can now take questions.

Question and Answer Session Operator

Thank you. At this time, we will be conducting a question and answer session.

Our first question comes from Jerry Su from UBS. You may begin.

Jerry Su, Analyst, UBS

The Company mentioned increased memory OSAT prices again in Q1 '26. What percentage will prices increase? Will the price increase be reflected in Q2 '26? And what is the CapEx to sales ratio in 2026? And impact on depreciation?

SJ Cheng, Chairman and President

Price increase are strategic and vary between customers and products. Therefore, it is not appropriate to provide a specific number here. Besides, a couple of customers prefer to consign the key assembly material. Under the current business environment, we would continue to negotiate the cost and price issue with customers. On the contrary, some smaller customers with smaller lot size could not get the assembly and test priority even with double price, which could adversely impact productivity.

As for 2026 CapEx, we still favor adopting the previous "Invest Taiwan Project" budget with lower interest rate.

Silvia Su, Vice President-Finance and Accounting Management Center

As for CapEx to sales ratio, it would roughly be between 22%-27% of 2026 annual revenue.

We expect the depreciation in coming quarters will have around a 1%-3% quarterly increase from our 4Q25 level.

Operator

The second question comes from Michael Hsu from Yuanta. You may begin

Michael Hsu, Analyst, Yuanta

Will there be any new customers under this year's CapEx plan for memory, logic and DDIC?

Jesse Huang, Spokesperson and Senior Vice President of Strategy and Investor Relations

Regarding memory product, we mainly serve current major customers. In order to maintain our productivity and efficiency, we don't provide service for those customers with smaller lot sizes. For the longer term, we continue to develop new customers in logic and mixed-signal product segment.

SJ Cheng, Chairman and President

Further, for example, the product application would be from MEMS and TV SOC products to include Mini LED and logic product for smart devices serving high-tech and healthcare. We also invest flip chip assembly capacity in order to meet future edge-AI device demand with high speed/frequency DRAM.

Michael Hsu, Analyst, Yuanta

Would you provide the CapEx allocation by product segment?

Silvia Su, Vice President-Finance and Accounting Management Center

Memory test would take around 50% of 2026 CapEx, logic about 10%, DDIC and bumping takes around 25%, and assembly around 20%.

SJ Cheng, Chairman and President

Importantly, some of the CapEx would be protected with 3 year take or pay contract. The majority investment in bumping is for the non-DDIC portion, including flip chip and RDL.

Operator

Thank you. And I am not showing any further questions in the queue. I would like to turn the call back over to GS Shen.

GS Shen, Technical Deputy Director of Strategy and Investor Relations

Thank you. I will read a question from our foreign institutional investors.

The question is about the low cost bump solution situation. What is different about this from current solutions?

Jesse Huang, Spokesperson and Senior Vice President of Strategy and Investor Relations

The current bump solution for DDIC is gold bump. It is well known that gold price is much higher than other precious metals, for example silver, copper, etc., and the price keeps rising. Our solution implements silver alloy bump instead of pure gold in the bumping process. The silver alloy bump solution has been qualified both by IC level and panel level reliability tests. Now that performance is qualified, we can provide a very cost effective bump solution to our customers about 50% to 60% lower, who can then get a better competitive cost structure in the DDIC market. Silver alloy bump product is designing in Tablet applications and sampling for mobile phones with customers.

GS Shen, Technical Deputy Director of Strategy and Investor Relations

That concludes our question and answer session. Thank you for participating. I'll turn the floor back to Mr. S.J. Cheng for any closing comments.

S.J. Cheng, Chairman and President

Thank you everyone for joining our conference call. Please email our IR Team if you have any more questions. We appreciate your support. Goodbye.
