    Gokul Hariharan's questions to GDS Holdings Ltd (GDS) leadership • Q2 2025

    Question

    Gokul Hariharan of JPMorgan Chase & Co inquired about the impact of the back-end loaded delivery schedule on 2026 growth and whether a reacceleration should be expected. He also asked for an update on customer conversations regarding AI orders, considering the ongoing chip supply uncertainties.

    Answer

    CFO Daniel Newman responded that the new capacity is for high-density AI inferencing with lower incremental revenue per square meter, and reiterated a high single-digit EBITDA growth target. He stated that the main sticking point for large AI orders remains chip supply uncertainty, with customers potentially waiting for next-generation technology. He emphasized that GDS is well-prepared with developable land and capital access for when demand materializes.

    Gokul Hariharan's questions to United Microelectronics Corp (UMC) leadership

    Gokul Hariharan's questions to United Microelectronics Corp (UMC) leadership • Q2 2025

    Question

    Gokul Hariharan of JPMorgan Chase & Co. questioned the ramp-up of the Singapore 22nm fab, the path back to mid-30s gross margins, and the roadmap for high-voltage technology below 22nm.

    Answer

    President Jason Wang confirmed the Singapore Fab 12i Phase 3 will ramp in January 2026, with healthy ASPs. He outlined the path to higher margins via better loading and product mix. CFO Qi Dong Liu added that depreciation growth will slow significantly in 2026, aiding the cost structure. Wang also confirmed a sub-22nm high-voltage solution is on the roadmap.

    Gokul Hariharan's questions to United Microelectronics Corp (UMC) leadership • Q1 2025

    Question

    Gokul Hariharan from JPMorgan Chase & Co. asked about the expected gross margin cadence in the second half, the full-year depreciation growth forecast, and whether the 22/28nm nodes have higher margins than the corporate average. He also inquired about potentially accelerating the Singapore P3 fab ramp and the customer profile and margin impact of the Intel collaboration.

    Answer

    CFO Chi-Tung Liu confirmed the depreciation growth forecast remains at high-20% for 2025 and noted that a one-off earthquake impact suppressed Q1 margin by about 2 percentage points. He explained that the margin for 22/28nm is complex due to new depreciation from fabs in Tainan and Singapore. The Singapore P3 ramp remains dynamic but is still scheduled for early 2026. Senior Director of Finance Michael (Jinhong) Lin identified WiFi and high-speed interface SoCs as key applications for the 12nm node, with Liu adding that its margin impact will depend on utilization.

    Gokul Hariharan's questions to United Microelectronics Corp (UMC) leadership • Q2 2024

    Question

    Gokul Hariharan of JPMorgan Chase & Co. asked about the key factors behind the significant Q2 gross margin beat, the sustainability of mid-30% margins amid rising costs, pricing differences between 8-inch and 12-inch nodes, the long-term utilization outlook for 8-inch fabs, and the revenue contribution from AI-related interposers.

    Answer

    President Jason Wang attributed the Q2 gross margin outperformance primarily to favorable foreign exchange rates. He expects Q3 margins to hold in the mid-30s despite higher depreciation and utility costs, with the EBITDA margin remaining firm. Wang noted that while like-for-like pricing is stable, blended ASP is affected by product mix. He acknowledged pressure on 8-inch utilization from 12-inch mature capacity but stated the goal remains 95%. CFO Chi-Tung Liu clarified that interposer revenue contribution is less than 4-5%.

    Gokul Hariharan's questions to United Microelectronics Corp (UMC) leadership • Q1 2024

    Question

    Gokul Hariharan of JPMorgan Chase & Co. asked for an updated full-year growth outlook for UMC versus the foundry industry and questioned the company's market presence in specialty technologies like RF-SOI. He also sought clarity on CapEx subsidies for the Singapore fab and plans for 8-inch capacity.

    Answer

    President Jason Wang revised the foundry industry growth forecast to low-teens, driven by AI servers, and stated UMC's addressable market now appears flattish for 2024, though the company aims to outperform it. He confirmed significant market share gains in RF-SOI but did not provide specific figures. CFO Chi-Tung Liu added that the Singapore government incentives include both tax breaks and capital expenditure subsidies. Mr. Wang noted that for 8-inch, UMC is exploring silicon carbide and gallium nitride, but these initiatives are in very early stages.

    Gokul Hariharan's questions to Taiwan Semiconductor Manufacturing Co Ltd (TSM) leadership • Q2 2024

    Question

    Gokul Hariharan from JPMorgan Chase & Co. inquired about the supply-demand balance for AI accelerators and CoWoS advanced packaging, asking for 2025 capacity expansion plans. He also questioned the future gross margin trajectory, including the potential to return to previous highs and the financial impact of government subsidies.

    Answer

    CEO C.C. Wei stated that AI-related demand is extremely high, and supply will remain very tight through 2025, with a potential easing in 2026. He confirmed plans to more than double CoWoS capacity again in 2025. CFO Wendell Huang addressed gross margins, reiterating the long-term target of 53% and higher is achievable, though reaching high 50s would require very high utilization. Huang explained that overseas fabs will dilute margins by 2-3 percentage points, and subsidies are used to offset asset values on the balance sheet, with Japan being a primary source of recent subsidies.
