NEW YORK, December 31, 2025, 05:02 ET — Premarket
Aimei Health Technology Co., Ltd shares rose 38% to $114 in premarket trading on Wednesday, extending Tuesday’s outsized move in the Nasdaq-listed blank-check company. The stock ended the prior session up 89% at $82.58 after trading in a wide range.
The spike matters because Aimei’s share count shrank sharply after recent redemptions, a setup that can amplify price swings when even modest buying hits a thin market. In a Dec. 2 filing, the company said shareholders redeemed 3,942,661 public shares for about $44.8 million, and that it would have about 2.18 million shares outstanding after the redemptions, with roughly $0.7 million left in its trust account.
The stock is also trading against a SPAC deadline. In an 8-K filed in early December, Aimei said it deposited $34,330.96 into its trust account to extend the period to complete an initial business combination by one month, moving its termination date to Jan. 6, 2026, and funded the deposit with a promissory note tied to a planned business combination with United Hydrogen Group Inc.
Tuesday’s rally came on about 918,000 shares traded, roughly four times the 65-day average, according to market data tracked by Finviz.
Aimei is a SPAC — a “blank-check” company that raises cash and looks for a private company to merge with — and that structure can create sharp, news-light moves when the pool of tradable shares gets small.
Traders call that a “low float,” meaning a limited number of shares are available to change hands. When supply is tight, price can gap higher quickly, and just as quickly reverse if early buyers take profits.
Premarket trading often exaggerates those swings because liquidity is thinner before the opening bell and a few prints can move the quote.
Investors will be watching whether the stock holds its early gains once regular trading begins and whether volatility triggers exchange pauses.
Technically, traders tend to key off round-number levels in fast movers. A sustained hold above $100 can keep momentum players involved, while a drop back toward the prior close would test how much demand is real versus purely tactical.
