Nukkleus Subsidiary Rimon Wins Multi-Year DefenseContracts to Build Iron Dome Components

Agreements with leading Israeli defense manufacturersprovide long-term revenue visibility and underscore the critical role of sub-tier suppliers in national defense programs

Rimon Agencies Inc.(“Rimon”), a well-established Israeli defense engineering and manufacturing firm and wholly owned subsidiary of Nukkleus,has secured multi-year contracts supporting Israel’s national missile defense and homeland security architecture. The agreements, signed with several leading Israelidefense original equipment manufacturers (OEMs), provide for Rimon to manufacture critical power and subsystem components for the IronDome anti-missile defense system, as well as components supporting additional mission-critical platforms deployed across national securityapplications. Together, these new contracts represent approximately $4.1 million in total value, in addition to Rimon’s existingprojected revenues, and provide Rimon with predictable, long-term revenue tied to active defense programs.These contracts highlight the structural evolutionwithin the defense industrial base, as critical performance drivers extend beyond the OEM level. As system complexity increases and operationaldemand accelerates, Tier-2 and Tier-3 suppliers are playing an increasingly important role, bringing specialized resilience, executionexcellence, and mission-ready capabilities in power, integration, and deployable systems that directly enable program success.Rimon operates directly within this executionlayer. Founded in 1988, Rimon designs and delivers customized platforms, combining power generation, communications, sensor infrastructure,mobility solutions, and human-centered work environments into cohesive, field-ready systems. These capabilities have made Rimon a trustedpartner for long-term defense programs for decades, where sub-system performance and operational reliability are non-negotiable.The newly awarded contracts reflect the industry-wideshift toward deeper, longer-term supplier relationships and align with Nukkleus’ strategy of assembling a portfolio of defense businessespositioned at structurally constrained points of the industrial base. Through its decentralized execution model, coupledwith centralized capital and strategy, Nukkleus provides funding, strategic direction, and operational alignment across its subsidiarieswhile preserving the domain expertise and customer intimacy required in defense execution.“These agreements highlight the importanceof the execution layer in modern defense programs,” said Menny Shalom, Chief Executive Officer of Nukkleus Inc. “Systems likethe Iron Dome rely not only on prime contractors, but on a network of highly specialized suppliers, capable of delivering critical subsystemsreliably and at scale. Rimon’s role in these programs reflects the long-cycle, mission-critical work that defines durable valuein the defense industrial base.”###About Nukkleus Inc.Nukkleus Inc.
