Sakuu Corporation to Go Public via Business Combination With Pyrophyte Acquisition Corp. II

Advancing Mission to Transform Energy Storage Manufacturing Industry by Supplying Commercial-Scale Dry-Printing Equipment for Accelerated, Sustainable and Cost-Effective Battery and Supercapacitor Production

SAN JOSE, Calif. & HOUSTON, October 15, 2026--Sakuu Corporation ("Sakuu"), a Silicon Valley-based company that seeks to become a global leader in the production and supply of transformative dry-printing electrode manufacturing platforms, and Pyrophyte Acquisition Corp. II ("Pyrophyte") (NYSE: PAII), a special purpose acquisition company, announced today that they have entered into a definitive Business Combination Agreement ("BCA") for a business combination.

The terms of the Business Combination imply a pre-money equity value of $600 million for Sakuu. The proceeds from the Business Combination are expected to be used to support the continued development and commercialization of Sakuu's Kavian® platform, its next-generation dry-battery printing platform, including preparations for anticipated commercial availability in the second quarter of 2027, and to support purchase-order fulfillment. Upon closing, Pyrophyte will be renamed Sakuu Corporation and is expected to be listed on the NYSE under the ticker symbol "SAKU." Unless otherwise specified, all amounts in this press release are in U.S. dollars.

Sakuu Overview

Founded in 2016, Sakuu develops the first known multi-material, multi-process additive manufacturing platform for energy storage production enabling electrode production in a fully dry process with proven electrode performance. It is the first company to 3D-print fully functional batteries in custom shapes and sizes with multiple materials, including metal-free composites, in a fully dry process.

For battery manufacturers, Sakuu's process and Kavian platform save both CapEx and OpEx, as well as significantly reduce factory and carbon footprints compared to traditional wet process manufacturing, thereby potentially improving gross margins. Sakuu believes the platform offers the potential to provide:

• 100% elimination of toxic solvents and water;

• 40-60% potential overall manufacturing cost reduction;

• 50% smaller factory footprint; and

• 55% reduction of CO2 emissions.

Additionally, Sakuu's polymeric current collector (PCC) technology and Kavian dry-printing manufacturing process enable the production of inherently safe batteries by dry-printing electrodes designed to mitigate the risk of thermal runaway associated with traditionally manufactured Li-Ion batteries.
