Check-Cap shares fall 14.04% premarket as Symetryx opposes merger with Keystone Dental.

Check-Cap (NASDAQ:CHEK) fell 14.04% in premarket trading as Symetryx Corp. opposed the proposed merger between Check-Cap and Keystone Dental, stating it would evaluate options to block the transaction. This development follows months of merger-related volatility, including earlier price swings driven by Symetryx’s fluctuating takeover offers and the merger’s initial announcement in August. The opposition introduces uncertainty over the deal’s completion, which had previously fueled investor optimism. Other recent news, including Check-Cap’s strategic workforce reduction and financial updates, predates the merger opposition and lacks direct linkage to the abrupt premarket decline.
