M-Tron Industries (MPTI) has DaysFromMergerAnn = 3. Usually a value in this field means that the stock is undergoing a merger. Most live strategies automatically trigger a sale when this is the case.
I strongly advise users not to sell the stock because of this merger flag. M-Tron is not undergoing a merger. Instead it is merely issuing warrants to stockholders, which will be valuable should the 30-day VWAP of the stock price exceed $52 at some point in the next 3 years. If that happens you can exercise the warrants for $47.50 and reap the difference. See https://ir.mtronpti.com/news/news-details/2025/M-tron-Industries-Inc.-Declares-Warrant-Dividend/default.aspx.
This warrant will be listed on the NYSE and thus qualifies, according to ICE data, as a spinoff. That's the reason for the merger flag.
