Suzhou Tfc Optical Communication Co.,Ltd. (300394.SZ) released its 2025 annual report on the evening of April 7. The company achieved revenue of 5.163 billion yuan, a year-on-year increase of 58.79%, and a net profit attributable to shareholders of 2.017 billion yuan, up 50.15% compared to the previous year. Amid the wave of exploding demand for AI computing power, optical components have garnered significant capital favor. Suzhou Tfc Optical Communication Co.,Ltd., along with other industry players, has seen its stock price surge dramatically. On April 8, the company's share price rose 6.19% to close at 337 yuan per share, with its market capitalization exceeding 260 billion yuan. Wind data shows the company's stock price has increased over 600% in the past year.
However, even high-growth companies face challenges. Both revenue and net profit for Suzhou Tfc Optical Communication Co.,Ltd. declined quarter-over-quarter in the fourth quarter of 2025, and the company's full-year gross profit margin also decreased compared to the previous year. Furthermore, the company's revenue is heavily reliant on its largest customer, Fabrinet, which contributed 63.31% of its total revenue, an increase of 1.62 percentage points year-on-year.
Despite being grouped with other leading optical module companies, Suzhou Tfc Optical Communication Co.,Ltd.'s business model differs. It positions itself as an overall solution provider for optical communication devices and an advanced optoelectronic packaging manufacturer, supplying components like optical parts and high-speed optical devices to module makers, thereby indirectly embedding itself into the global computing power supply chain.
The company attributed its 2025 performance to accelerated development in the AI industry and global data center construction, which drove sustained growth in demand for high-speed optical devices. Enhanced intelligent manufacturing processes also contributed to cost reductions and efficiency gains, promoting revenue growth across both its active and passive product lines.
A quarterly breakdown reveals that while net profit saw a slight sequential increase to 566 million yuan in Q3 2025, revenue had already begun to decline, falling from 1.511 billion yuan in Q2 to 1.463 billion yuan. This trend worsened in Q4, with revenue dropping 14.87% sequentially to 1.245 billion yuan and net profit decreasing 2.51% to 552 million yuan.
The company cited risks in its annual report, including potential tight supply, extended delivery times, and price fluctuations for key materials due to factors like upstream capacity release schedules and yield ramp-up. These factors could adversely affect order fulfillment, costs, gross margins, and the production speed of new products.
Notably, the gross profit margin for its core optical communication components business fell by 3.67 percentage points year-on-year to 53.62% in 2025. By product line, passive optical devices maintained a higher gross margin of 63.67%, while active optical devices had a margin of 46.63%. Revenue from active optical devices grew 81.11% to 2.998 billion yuan, and passive optical devices revenue increased 32.23% to 2.084 billion yuan. The revenue contribution from active devices rose from 50.91% in 2024 to 58.06% in 2025.
The company acknowledged intense competition in the optical device industry, leading to price pressure. It warned that if product prices continue to fall without a corresponding decrease in unit costs—due to factors like raw material costs, technological maturity, and limited efficiency gains—coupled with higher initial production costs at its new Thailand facility, gross margins could face further downward risk.
The company's growth is closely tied to its largest customer, resulting in high customer concentration. From 2023 to 2025, the proportion of revenue from its top five customers increased steadily, reaching 89.73% in 2025. Revenue from its largest customer, Fabrinet, accounted for 53.61%, 61.69%, and 63.31% over the same three-year period. Fabrinet, a major global optical transceiver manufacturer with primary operations in Thailand, provides advanced optical packaging and precision electronics manufacturing services and is involved in AI infrastructure projects for leading tech companies.
Suzhou Tfc Optical Communication Co.,Ltd. highlighted the risk that any slowdown in demand or changes in procurement policies from its major clients could lead to operational volatility due to this high concentration.
While the proportion of overseas sales slightly decreased from 76.06% to 74.35% in 2025, the absolute value of international sales surged significantly from 2.473 billion yuan to 3.839 billion yuan. This growth in foreign revenue also exposed the company to exchange rate loss risks. The company reported that financial expenses increased year-on-year in 2025 due to exchange rate losses, negatively impacting performance. Financial expenses rose from -90.678 million yuan the previous year to -30.6151 million yuan.
The company continues to expand its overseas footprint. It stated in an investor briefing on November 27, 2025, that the first phase of its Thailand production base commenced operations in mid-2024 and is currently ramping up capacity based on client demand. The second phase became operational in 2025, with full product line capacity expansions expected by 2026.
To advance its international strategy and global layout, Suzhou Tfc Optical Communication Co.,Ltd. is planning a listing in Hong Kong. On April 2, an interim shareholders' meeting approved a proposal for the company to issue H-shares and list on The Stock Exchange of Hong Kong Limited.
