The deal, financed via unsecured convertible promissory notes, marks a strategic pivot for the Hong Kong construction firm into the electronics and industrial heating sectors.

# Ming Shing Group (MSW) Stock Surges Over 200% After Hours: What's Going On?

**Ming Shing Group Holdings Ltd.** (NASDAQ:MSW) shares surged 203.62% to $4.01 in after-hours trading Tuesday after the Hong Kong-based construction firm announced the closing of its $110 million acquisition of **PMA Nano Carbon Tech Limited**.

## Construction Firm’s Pivot Into Graphene Thermal Solutions

PMA Nano Carbon Tech is a Singapore-based developer of graphene-based thermal management and heating solutions. It specializes in thin, lightweight heat-spreading components that use graphene's high thermal conductivity. This is a fast-growing segment in electronics and industrial applications.

The deal, first announced on May 26, was fully financed through unsecured convertible promissory notes, which were issued to the three sellers of PMA's entire issued share capital, **PMA Technology Holdings Limited**, **Legend Master Development Limited** and **F.F. Formation Holding Co. Ltd.**

## What You Should Know

The all-note structure raises meaningful dilution risk for existing shareholders.

Ming Shing's core business, plastering, tile laying and floor screeding in Hong Kong, has no operational overlap with its newly acquired graphene unit.

Over the past 12 months, MSW has dropped 69.93%.
