NuCube Energy Discloses NuSun Platform Output Configurations Ahead of Planned Merger

NuCube Energy, Inc., a Delaware corporation, submitted a Form 425 filing on October 27, 2026, reproducing social media posts it published that day on LinkedIn and X. The posts relate to the company's NuSun platform and were filed in connection with the previously disclosed proposed business combination between NuCube and Launch Two Acquisition Corp., a Cayman Islands exempted company. The Form S-4 registration statement underlying that transaction was filed by Launch Two on September 11, 2026, with NuCube named as a co-registrant.

The social media communications describe the distinction between two nuclear energy output measurements. According to the filing, MWe refers to electrical output while MWth refers to thermal output, described as "the heat produced by the reactor." The posts state that the NuSun platform is being developed in two configurations: NuSun-1 at approximately 1.3 MWe and 4 MWth, and NuSun-15 at approximately 15 MWe and 45 MWth. The filing quotes the platform as being "designed to provide both electricity and high-temperature heat," or, as stated in the X post, "electricity or high-temperature heat."

Because the posts were made in connection with a pending business combination subject to SEC registration requirements, they were filed under Rule 425 and deemed filed under Rule 14a-12. No financial results, transaction pricing, or closing timeline information was included in the disclosed communications.
