PLANET VENTURES HIGHLIGHTS SIGNIFICANT STRATEGIC MILESTONE ACHIEVED BY PORTFOLIO COMPANY ANTARIS AND RENEWS INVESTOR AWARENESS AGREEMENT WITH INVESTOR INSIGHTS SYSTEMS INC.

Planet Ventures Inc. has highlighted a significant milestone achieved by its portfolio company, Antaris, following Antaris's announcement on May 6, 2026, regarding the signing of a memorandum of agreement (MoA) with Transcelestial to jointly develop and demonstrate a persistent intelligence, surveillance and reconnaissance (ISR) architecture integrated with high-throughput optical communications in low Earth orbit (LEO).

According to Antaris, the collaboration will be flight validated on its coming Janus-2 mission, targeted for the fourth quarter of 2026. The initiative is intended to demonstrate a next-generation space infrastructure platform that combines advanced sensing capabilities with secure, high-speed optical communications, addressing growing demand from both commercial and defence markets. Antaris stated that the mission will validate technologies designed to accelerate data transmission, reduce latency and enhance real-time decision making in space-based operations.

The agreement represents another important step in Antaris's evolution as a leading provider of software-defined space infrastructure solutions. Antaris's platform enables the design, simulation, manufacturing and operation of satellite constellations through a cloud-based architecture intended to simplify mission deployment while reducing cost and time to orbit.

"Antaris continues to execute on its vision of becoming a foundational software and mission management platform for the rapidly expanding space economy," said Etienne Moshevich, chief executive officer of Planet Ventures. "The company's ability to attract strategic partners and participate in cutting-edge initiatives involving optical communications, artificial intelligence and space-based ISR capabilities demonstrates the strength of its technology platform and the growing market opportunity ahead. We believe this announcement further validates our investment thesis and highlights the substantial value creation potential within Planet's portfolio."

The global space economy is expected to experience significant growth over the coming decade, driven by increasing demand for satellite communications, Earth observation, defence applications and AI-enabled (artificial intelligence) space infrastructure. The integration of high-bandwidth optical communications with persistent sensing capabilities is increasingly viewed as a key enabling technology for future satellite networks and real-time space operations.

Planet Ventures remains an equity shareholder of Antaris and continues to monitor the company's progress as it advances toward the Janus-2 mission and additional commercial opportunities.
