Semiconductor Landscape  Opportunities: Likely to reach $1T in the next decade driven by AI, Robotics, EV, ADAS, Energy, XR, IoT  Responsibilities: Net Zero, ESG, circular economy/recycling  Challenges : Geopolitical tensions, Regionalization, Market bifurcation, Added - cost , Reduced - scale  To do’s  More innovation with higher value  Structural improvement of efficiency and cost  Align talent and workforce with complexities of doing businesses 15

ASE’s Competitive Advantages  Technology  HPC/AI: Taiwan ecosystem and technology leadership  SiP : Heterogeneous integration, embedded devices  Optical: Silicon Photonics, CPO  Automation: Software/Data/Design Ecosystems  Scale efficiencies  Strong financial performance and cash flow  Flexibility/agility to handle business model evolutions  Geographical diversity 16

2024 Outlook (1/2)  Revenues recovery with faster pace of advanced packaging and testing  Coming out of inventory adjustment in 1H24. Expect growth to accelerate in 2H24 with full year ATM revenues to grow at a similar rate with the logic semiconductor market  Expect a higher revenue mix of Advanced Packaging on technology leadership and Testing on increasing turnkey ratio  Target higher investments in machinery, building, and smart factory compared to 2023 as we are entering into a new industry upcycle and increasing adoption of advanced technology 17

2024 Outlook (2/2)  Well - positioned to participate in the AI boom  On track to double leading - edge advanced packaging revenues from existing customers with at least an additional 250 million USD revenues in 2024; we expect momentum to continue  A comprehensive technology toolbox (3D, 2.5D, Fanout, SIP, CPO, automation) and scale advantages make ASE the preferred partner for customers  ASE will not only benefit from the adoption of leading - edge advanced packaging, but also the expansion of mainstream packaging, which will be utilized to address the growing semiconductor demands for all the surrounding chips of the booming AI ecosystem 18

First Quarter 2024 Outlook Based on our current business outlook and exchange rate assumptions, management projects overall performance for the first quarter of 2024 to be as follows:  In NT dollar terms, our ATM 1st quarter 2024 revenues and gross margin should be similar to the 1st quarter 2023 ;  In NT dollar terms, our EMS 1st quarter 2024 revenues should be similar to the 1st quarter 2023;  Our EMS 1st quarter 2024 operating margin should approach 1st quarter 2023 operating margin. 19
