Exhibit 99.1

Maris-Tech to Showcase Edge-Based Video Intelligence at Milipol TechX 2026 in Singapore

Enabling real-time, onboard video analytics for mission-critical operations across contested and bandwidth-constrained environments

Rehovot, Israel, April 13, 2026 (GLOBE NEWSWIRE) -- Maris-Tech Ltd. (Nasdaq: MTEK, MTEKW) (“Maris-Tech” or the “Company”), a global leader in video and artificial intelligence (“AI”)- based edge computing technology, today announced its participation in Milipol TechX Summit 2026 (Milipol TechX), taking place on April 28–30, 2026 at the Sands Expo and Convention Centre in Singapore. Maris-Tech will exhibit at Booth L1-R15.

At this year’s event, Maris-Tech will present its latest innovations in real-time video intelligence at the edge, demonstrating how onboard processing is designed to transform raw video into actionable insights.

Modern defense and security operations often require immediate situational awareness without reliance on centralized infrastructure. Maris-Tech addresses this need by enabling intelligence to be generated directly at the source – where data is captured – allowing operators to detect, analyze, and respond in real time.

The Company will highlight three core operational use cases:

SituationalAwareness and Terrain Dominance

Maris-Tech’s solutions enable 360° 3D visibility and real-time threat detection, supporting enhanced operational control across complex terrain.

Drone-BasedEdge AI for Small UAVs

Designed for size, weight, and power (“SWaP”)-constrained platforms, Maris-Tech’s onboard processing capabilities allow small unmanned aerial systems to perform real-time video analytics, reducing dependency on high-bandwidth communication links.

IntelligenceGathering in Low-Bandwidth and Covert Environments

Maris-Tech enables reliable intelligence collection and analysis in environments where connectivity is limited, disrupted, or intentionally restricted.

“Operational environments today demand immediate access to actionable intelligence, regardless of connectivity conditions,” said Israel Bar, Chief Executive Officer of Maris-Tech. “Our technology is designed to bring intelligence closer to the point of capture, enabling real-time decision-making in the most constrained and demanding scenarios. Participation in Milipol TechX provides an important opportunity to engage with strategic partners and customers focused on next-generation operational capabilities.”

Visitors to Booth L1-R15 will have the opportunity to explore how Maris-Tech’s edge-based design supports real-time processing, adaptive streaming, and efficient data utilization across defense, homeland security, and tactical intelligence applications.
