NEW YORK, December 31, 2025, 06:39 ET — Premarket
- A SPAC III Acquisition shares were higher ahead of the open after a sharp gain in the prior session.
- The move keeps the blank-check company on traders’ screens in holiday-thin markets.
- Investors are watching for the next regulatory and shareholder-vote steps tied to the Bioserica deal.
Shares of A SPAC III Acquisition Corp (ASPC) rose 12% in premarket trading on Wednesday to $30.89, extending a volatile year-end run in the blank-check company. The stock traded between $30.21 and $30.94 in early hours, according to Public.com data. 1
The premarket move followed a 14.9% jump in the prior session, when ASPC ranked among the biggest SPAC gainers tracked by Boardroom Alpha. Other announced-deal SPACs on that list posted far smaller moves, including ESH Acquisition (ESHA) and Trailblazer Merger Corp I (TBMC). 2
SPACs, short for special purpose acquisition companies, raise cash in an IPO and then seek to merge with a private company. Their shares can swing sharply when liquidity dries up and traders crowd into a small float.
A SPAC III has a merger agreement with Bioserica International Limited, which the company has described in filings as a business focused on bio-based antimicrobial materials. 3
In an October proxy statement, A SPAC III said the deal process would require filings with the China Securities Regulatory Commission and the U.S. Securities and Exchange Commission, and that a separate shareholder meeting would be held later for the business-combination vote. The company also said it expected “significant redemptions” at its extraordinary general meeting and that its sponsor did not plan to contribute funds to extend the deadline under its current charter terms. 4
Redemptions let SPAC investors take their cash back instead of staying in the deal, a standard feature of the structure. Big redemptions can shrink the shareholder base and amplify price moves when trading turns one-sided.
With ASPC changing hands above Tuesday’s close, traders will be watching whether the stock can hold above the $30 level as regular trading begins at 9:30 a.m. ET. The premarket high just below $31 may act as an early reference point for momentum traders.
Broader markets have been trading in thinner, year-end conditions, a setup that can magnify idiosyncratic moves in smaller names. “It’s just a healthy rebalancing of allocations more so than an emotionally driven sell-off,” Mark Hackett, chief market strategist at Nationwide, said in a market note on Tuesday. 5
That backdrop matters for ASPC, which has been moving more like a momentum stock than a typical SPAC that tracks its cash-in-trust value. In holiday trading, even modest bursts of buying or selling can push prices around.
Investors will be watching for any fresh SEC filings that clarify the timeline for the Bioserica transaction, including the proxy statement/prospectus used to solicit votes. Traders will also be looking for signs of whether the premarket strength carries into the open with sustained volume.
