POET closes US$400 million investment for AI/datacenter photonics expansion

POET Technologies said it has closed a US$400 million investment that will fund expansion in its AI and datacenter photonics business.

The company announced the closing on May 18, 2026. It said the financing was a registered direct offering of common shares and warrants to a single institutional investor.

According to the company, POET sold 19,047,620 common shares and an equal number of warrants at US$21.00 per unit. That price was above the Nasdaq closing price of US$20.57 on May 14.

POET said it plans to use the proceeds for manufacturing expansion, research and development, targeted acquisitions, operations and working capital. The company also framed the raise as support for its broader growth plans in AI and datacenter photonics.

The identity of the investor was not disclosed in the company materials cited in the reporting, and the final net proceeds after fees and expenses were not detailed.

The closing follows POET's earlier announcement of the deal on May 15, and the company said the financing is now complete.
