POET Technologies shares dropped again Tuesday as the Toronto photonics firm wrapped up a $400 million financing deal to speed up its AI data-center push. The stock finished 8.02% lower at $13.07 on Nasdaq, carrying on with losses after last week’s strong rally.
POET is in a key period as it looks to scale up. The company makes photonic integrated circuits—chips that use light to transfer data—for AI systems and hyperscale data centers used by large tech companies.
POET said Monday it has issued 19,047,620 common shares and a matching number of warrants to one institutional investor. The warrants allow buying another 19,047,620 shares at $26.25 over three years.
MMCAP International Inc. SPC was named as the buyer in a U.S. Securities and Exchange Commission filing. The company expects net proceeds of roughly $399.7 million after expenses, according to the document. Securities sold at $21 for each share-and-warrant package, and there was no placement agent, the filing said.
POET CEO Suresh Venkatesan said the company is “expanding our capacity by roughly ten-fold” for wafer production and optical-engine assembly as it looks to ramp up manufacturing into 2027. Optical engines move data through servers by converting electrical signals to light and back, using less power in the process. poet-technologies.com
POET’s cash position follows a rough period. In late April, the company reported Marvell Semiconductor canceled every POET order from Celestial AI, a firm Marvell bought, pointing to supposed breaches of confidentiality around purchase order and shipping data. POET at the time said it was still working with other customers and pointed to a new order worth roughly $5 million.
POET is still small by revenue. The company posted first-quarter non-recurring engineering and product revenue of $503,389, up from $166,760 in the same quarter last year. Net loss was $12.3 million. Non-recurring engineering refers to one-time development work, not regular product sales.
Lumilens is the standout commercial driver for now. POET said last week that Lumilens has made an initial $50 million order for electrical-optical interposer-based engines, and the deal could scale up to more than $500 million over five years. The first engineering samples are targeted for late 2026, with production expected to ramp as hyperscalers deploy gear in 2027. Delivery will depend on development and product qualification, as well as manufacturing ramp.
Lumilens CEO Ankur Singla called GPU interconnects the “defining bottleneck for scaling AI.” Co-founder Venkatesan said the deal could add “semiconductor-style manufacturing discipline” to optical engines. But those are promises for the future. The market wants to see evidence.
Rivals aren’t standing by. Coherent and Lumentum have high-speed optical transceivers on the market aimed at AI and cloud data centers. Coherent says it is already shipping 800G transceivers in production. Lumentum’s lineup includes 800Gbps and 1.6Tbps modules targeting AI and cloud data centers.
Nasdaq dropped 0.8% Tuesday, logging its third straight loss. That weighed on most stocks, but POET tumbled harder, hit by worries over dilution as the company issued new shares and by execution risk.
Risks are out there. POET could run into trouble if Lumilens drops, Marvell work isn’t swapped out, or production growth falls behind schedule. The new cash might just delay things if sales don’t follow. POET flagged the risks, saying outcomes could shift based on production needs, acquisition or partnership trouble, product demands, or scaling up its manufacturing.
The stock right now isn’t about financing. It’s about execution. Investors know the company has cash, but they want to see shipments, qualification milestones hit, and recurring revenue come through.
