The facility has a maximum commitment of $500 million, with the option to increase to $750 million through additional commitments from existing or new lenders. The credit agreement, amended and restated in 2024, will be used for general corporate purposes, including working capital, capital expenditures and potential acquisitions. Specific terms such as interest rates and covenants were not disclosed in the filing but will be detailed in the final agreement. The move reflects broader trends in energy infrastructure financing, with similar recent expansions by Ecoplexus and Jupiter Power to support renewable energy and storage projects.
Riverside Research partners with Plexus. 0 Comments On May 19, Riverside Research announced a strategic partnership with Plexus Corp., a global leader in designing, manufacturing, and servicing highly complex products in demanding regulatory environments, to rapidly develop designs for reusable modular-based hardware and software for the intelligence and defense markets. This partnership will deliver technology that uses a collaborative rapid prototyping approach to create adaptable, ultra-secure, connected devices. This is a critical step in addressing security concerns and decreasing time-to-market for such devices, which is essential as adversaries' technologies swiftly adapt to challenge the nation's security architecture, the company said. In their first joint effort, Riverside Research and Plexus developed the Aegis R52L Enhanced Retransmission Device, designed to secure end-user devices. Together, they moved from the initial concept to identifying requirements, developing prototypes and planning for full-scale manufacturing in under nine months. This pace sets a new standard for bringing these commercially viable technologies to market. "Partnering with Riverside Research aligns with our vision to help create the products that build a better world by enabling the rapid deployment of secure, cutting-edge technologies that protect freedom, people and the dedicated soldiers who serve our nation," said Jim Stokes, Plexus market sector vice president, aerospace/defense. "We are committed to accelerating their time-to-market through our integrated engineering and manufacturing solutions." "Too often, industry has been forced to navigate the complex ecosystem of defense contracts to fulfill the entirety of the product development process," said Carl Nerup, vice president, business development, at Riverside Research. "With Riverside Research and Plexus aligned, the marketplace now has an innovation engine. Together, we're combining our companies' world-class problem-solving abilities to guide customers smoothly from concept to product." Your competitors read IC News each day. Shouldn't you?
