Microcap Companies See Broad Developments in Nuclear Energy, Tech, and Pharma

Mangoceuticals' deal with Nuclea Energy centers on the Morpheus lead-cooled, factory-built micro-modular reactor, with Nuclea based in Mississauga, Ontario and founded in 2023; the 18-month roadmap targets engineering, regulatory milestones, and commercial readiness.
Peraso's 60 GHz mmWave technology is being positioned for robotics and electronic warfare in addition to its existing focus on military drones, AI infrastructure, autonomous systems, and secure communications.
The microcap cohort includes Mangoceuticals (MGRX), Peraso (PRSO), IGC Pharma (IGC), and Kustom Entertainment (KUST) with tickers listed on NASDAQ or NYSE, highlighting cross-exchange activity among these small-cap names.
Four microcap stocks — Mangoceuticals (NASDAQ: MGRX), Peraso (PRSO), IGC Pharma (NYSE: IGC), and Kustom Entertainment (NASDAQ: KUST) — are drawing fresh attention across nuclear energy, defense tech, and biotech. The biggest headline: Mangoceuticals has struck a deal to develop a micro-modular nuclear reactor, pivoting hard from its origins as a men's health company, according to Street Insider.
The moves come as small-cap investors hunt for momentum plays across a wide range of sectors. These four names span everything from next-generation wireless chips to pharmaceutical fraud fallout, reflecting how broad and volatile microcap activity can be.
Mangoceuticals has signed a definitive business combination agreement with Nuclea Energy, a company founded in 2023 and based in Mississauga, Ontario, according to Financial Content. The deal centers on the Morpheus reactor — a lead-cooled, factory-built micro-modular reactor designed to deliver carbon-free power. The partnership comes with an 18-month development roadmap.
That roadmap covers three key phases: engineering, regulatory milestones, and commercial readiness. The goal is to give Mangoceuticals access to clean, scalable power. The move puts the company squarely in the fast-growing advanced nuclear sector, a space attracting significant investment from both governments and private backers, Capital City Rock reported.
Peraso Inc. will report its Q2 2026 earnings on August 11, 2026. The company makes 60 GHz mmWave chips — high-frequency wireless technology that can send large amounts of data at very short range. Its targets include military drones, AI infrastructure, autonomous systems, and secure communications, according to Street Insider.
Now Peraso is pushing into two more areas: robotics and electronic warfare. Electronic warfare means using radio signals to jam or disrupt enemy systems. Both markets are growing fast as defense budgets rise. Peraso competes on performance in next-generation wireless networking, a space where speed and reliability can mean the difference between mission success and failure, KBEW reported.
IGC Pharma is in focus for a different reason. The company is evaluating recovery options as investors pay renewed attention to the securities fraud conviction of Andrew L., founder of Citron Research, according to Eagle Country. Citron Research is a well-known short-selling firm that has targeted many small-cap stocks over the years.
The conviction has sparked scrutiny among investors who want to understand what, if any, impact the case has on companies Citron previously targeted. IGC Pharma has not disclosed specific recovery steps yet. The situation adds uncertainty to an already volatile microcap name listed on the NYSE.
Kustom Entertainment (NASDAQ: KUST) rounds out the group of four names drawing investor attention. While specific catalysts for KUST were not detailed in current reporting, its inclusion alongside a nuclear energy deal and a defense chip maker shows how broad microcap momentum can be, according to Financial Content.
Together, MGRX, PRSO, IGC, and KUST cover nuclear power, mmWave wireless, pharmaceutical litigation, and entertainment. All four trade on major U.S. exchanges. That cross-sector, cross-exchange activity is a hallmark of microcap cycles, where news flow — not fundamentals — often drives short-term price moves.
