Acquisition priced at $374, but stock floating around $340. Easy 10% gains?

Hoping someone here can educate me- Last month, Boston Scientific (BSX) announced they would buy Penumbra (PEN) for $374 per share. press release here: [https://news.bostonscientific.com/2026-01-15-Boston-Scientific-announces-agreement-to-acquire-Penumbra,-Inc](https://news.bostonscientific.com/2026-01-15-Boston-Scientific-announces-agreement-to-acquire-Penumbra,-Inc) The deal is expected to close by end of year. when similar acquisitions have been announced in the past, the acquired company’s stock price instantly jumps to the announced acquisition price. In this case, PEN experienced a bump, then dropped a bit. It’s now been level for a couple of weeks at 10% below there announced acquisition price. Is this a sign of uncertainty about the deal ever closing? the BSX press release states that there is a $900M penalty if they pull out of the deal, and there a $500M penalty if PEN pulls out of the deal. Seems like decent motivation to keep it alive, even if the terms are tweaked. So is this an opportunity for buyers, knowing that a price of $374 in very nearly a certainty? What else could cause the price of PEN to hover 10% below $374, despite not seeing that in similar deals ?
