Mint shares surge 37.73% after-hours as speculative trading drives volatility in microcap stock.

Mint Incorporation Limited (MIMI) surged 37.73% in after-hours trading following a major shareholder’s conversion of 2.1 million Class B shares (with 20-vote rights) to Class A shares (one-vote rights). This action, announced on December 11, 2025, diluted AL Holding Group’s concentrated voting control while maintaining its equity stake, signaling a shift toward a more balanced corporate governance structure. The move likely attracted investor confidence by reducing perceived risks of concentrated control, aligning with the stock’s sharp post-announcement rebound. Other news, including unrelated U.S. Mint director nominations or Italy’s PagoPA sale, lacked direct relevance to MIMI’s fundamentals. Technical indicators, such as an oversold RSI (12.94), also suggest short-term speculative buying, though governance-related catalysts appear to have driven the after-hours momentum.
