Key Terms

6 terms

blank check company financial

"TDAC is a blank check company incorporated for the purpose of effecting a merger"

A blank check company is a publicly listed shell that raises money from investors before naming a specific business to buy or merge with, similar to handing a cashier a signed check and asking them to fill in the payee later. It matters to investors because it offers a faster, often cheaper path for private firms to become public, but carries extra risk since returns depend on the organizers’ ability to find a good deal and on limited information about the future business.

registration statement on Form F-4 regulatory

"ProLogium has filed a registration statement on Form F-4 with the SEC"

A registration statement on Form F-4 is a regulatory filing used when a foreign company offers or issues securities in connection with a merger, acquisition, exchange offer or similar transaction that involves U.S. securities law. It gathers the deal terms, financial statements, management background and risk factors into one disclosure package so investors can evaluate the transaction — like an ingredient list and instruction manual investors read before deciding to buy or vote on the new or exchanged shares.

proxy statement / prospectus regulatory

"includes a prospectus with respect to ProLogium’s securities and a proxy statement"

A proxy statement and a prospectus are formal documents companies provide to investors: a proxy statement explains items shareholders will vote on at a meeting (like electing directors or approving pay) and serves like an agenda with background information, while a prospectus describes the details, risks and terms of a new securities offering, like a product brochure with price and safety notes. Investors use these papers to judge governance, potential dilution, costs and risks before voting or buying, much like reading a menu and warranty before choosing a product.

forward-looking statements regulatory

"This communication contains forward-looking statements within the meaning of Section 27A"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

GWh-class gigafactory technical

"ProLogium’s first GWh-class gigafactory, Taoke facility, is located in Taoyuan"

next-generation lithium ceramic battery technical

"strategy to commercialize next-generation lithium ceramic battery and expand our global footprint"

This commitment represents more than financial backing. It reflects the continued confidence of long-term shareholders who have supported ProLogium’s journey, recognizing our technological leadership, execution capabilities, and long-term vision. It also underscores strong market confidence in our strategy to commercialize next-generation lithium ceramic battery and expand our global footprint.

We sincerely thank our existing shareholders for their continued trust and support as we enter this important new chapter.

Key highlights:

Strengthened market confidence: Continued investment from existing shareholders reinforces confidence in ProLogium’s technology, commercialization capabilities, and long-term growth strategy.

Accelerating commercialization: The investment is expected to support the expansion of next-generation lithium ceramic battery mass production, advance construction of ProLogium’s Dunkirk Gigafactory in France, and accelerate growth across emerging applications, including data centers, aerospace, and robotics.

Every act of support is a vital force driving innovation forward; every new partner who joins makes the path from technological breakthrough to large-scale application of next-generation lithium ceramic batteries all the more solid. This is a milestone achievement worth sharing together, and also the beginning of another journey. ProLogium will continue to engage and collaborate, with a pragmatic and prudent approach, with more investors, industry partners, and global collaborators who share our long-term vision.

Looking ahead, ProLogium will continue to engage with investors, industry partners, and collaborators around the world who share our long-term vision, working together to deliver safer, higher-performance, and scalable energy solutions that accelerate the global adoption of next-generation lithium ceramic batteries.

About ProLogium

Founded in 2006, ProLogium is an energy innovation company dedicated to the development and manufacturing of next-generation lithium ceramic batteries, holding over 1,100 global patents (granted and pending). In 2013, ProLogium commercialized solid-state batteries, primarily for use in smartphones charging cases and since then, ProLogium has delivered in the aggregate more than 2.4 million battery products to its collaboration partners and customers, including cells used in automotive audio systems and approximately 10,000 samples for automotive applications. In 2025, ProLogium introduced superfluidized inorganic next generation lithium ceramic battery, integrating the advantages of solid-state and liquid type batteries and redefining next-generation battery technology with scalable manufacturability and cost competitiveness. In 2026, ProLogium once again received the Edison Awards Gold Award for its superfluidized inorganic next generation lithium ceramic battery technology.

With more than 13 years of manufacturing know-how, ProLogium is among the first companies to successfully commercialize a high-efficiency roll-to-roll coated ceramic separator manufacturing process and its Taoke facility announced that it was the first commercial next-generation lithium ceramic battery gigafactory to publicly display the production line—reflecting that next generation lithium ceramic batteries represent a feasible solution for scalable manufacturing rather than a laboratory project. ProLogium’s first GWh-class gigafactory, Taoke facility, is located in Taoyuan, Taiwan. In 2024, ProLogium established its first overseas R&D center in Paris-Saclay, France, providing customized technical support for the European market. ProLogium’s second battery gigafactory is located in Dunkirk, France, where groundbreaking for its Phase 1 facility took place in February 2026 and the project is proceeding to the detailed design and construction stage. The Phase 1 facility will have a designed production capacity of 4.0 GWh when complete, which ProLogium expects to achieve gradually by 2030. The Dunkirk facility site will have a maximum designed production capacity of 44.0 GWh and is intended to work closely with ProLogium’s Paris-Saclay R&D center.
