Serenity criticizes Sivers management over vague listing timeline and weak messaging on laser capacity

Serenity, known in Chinese crypto circles as the “white-haired stock guru,” criticized optical communications laser maker Sivers (SIVE) for what he described as weak messaging during its recent earnings communication. According to Odaily, Serenity said management failed to highlight the potential commercial value of the company’s laser production capacity and did not make a clear commitment on its Nasdaq listing timeline, a combination he said could deepen market concerns about Sivers’ near-term execution. At the same time, Serenity did not dismiss the company’s longer-dated opportunities. He pointed to Sivers’ plan to add annual capacity for 100 million CW DFB lasers in the fourth quarter of 2027, arguing that the expansion could arrive during a period of tight industry supply. He also noted that Lumentum’s capacity is sold out through 2029, while Coherent and Applied Optoelectronics have shifted part of their laser capacity toward internal product programs. In his view, that setup may create room for Sivers to win customers and capacity agreements. Serenity also said Sivers’ commercialization opportunities with Jabil and GlobalFoundries, along with its previously positioned co-packaged optics, or CPO, project, could see key progress starting in 2027.

Sivers Expands InP Capacity, AI Optical Communication Market May See Billions

Sivers Semiconductors plans to expand its indium phosphide (InP) manufacturing capacity in Glasgow, Scotland, targeting annual production of 100 million CW DFB lasers by Q4 2027. Serenity estimates the new capacity could generate $625 million to $1.25 billion in annual revenue, based on historical pricing of $50-$100 per 8-laser array, highlighting the tight supply in AI data center optical interconnects.

AMD’s Advancing AI event puts MI500 and CPO roadmap in focus

AMD is set to host its Advancing AI event in San Francisco on July 22-23, where the company is expected to share more details on its MI500 GPU series and its scale-up co-packaged optics, or CPO, roadmap. In comments relayed by Serenity, the key issue is whether AMD will explicitly commit to a CPO approach and identify its optical engine supplier. If that happens, Serenity said, the development would be positive for the broader CPO theme because it would show that the push toward optical interconnects is no longer driven by Nvidia alone. Jefferies analyst Blayne Curtis currently expects AMD to work with Astera Labs on UAL and with Broadcom on ESUN, but Serenity said the market still needs to see whether AMD formally shifts to a CPO-based scale-up design. The firm added that supply-chain signals should become clearer only after the event, while Sivers remains tied to the story through indirect links involving GlobalFoundries and Ayar Labs.

Serenity says limited wafer allocation could support hundreds of millions in gross profit for Sivers

Serenity said Sivers could generate substantial revenue and gross profit even with a relatively small wafer allocation from foundry partner Win Semi, based on assumptions around yield and average selling prices. Under the scenario outlined, a roughly 10% wafer capacity allocation, paired with a 65% yield and ASP of $50 to $75, would translate into annual revenue of $341 million to $512 million for Sivers’ optical array products. Using management’s gross margin target of more than 50% to 60%, that implies annual gross profit of about $205 million to $307 million. At Sivers’ current market capitalization of about $1.1 billion, Serenity said that would put the company at roughly 3.6x to 5.4x gross profit. If wafer allocation rises to 15%, annual gross profit could increase to $307 million to $461 million, lowering that valuation range to 2.4x to 3.6x. Serenity also pointed to capacity expansion efforts, broader supply chain qualification since 2024, tight CW laser supply, and production progress with partners including GlobalFoundries, Jabil, Ayar Labs, POET, and O-Net. The note added that Morgan Stanley recently listed Sivers among the three core players in CPO lasers alongside Coherent and Lumentum.
