Penumbra ( (PEN) ) has provided an update.
On January 14, 2026, Penumbra, Inc. entered into a definitive merger agreement under which Boston Scientific will acquire Penumbra through a merger of a Boston Scientific subsidiary into Penumbra, leaving Penumbra as a wholly owned subsidiary of Boston Scientific. At closing, each Penumbra common share will be converted into either 3.8721 Boston Scientific shares or $374 in cash, subject to shareholder elections and proration so that roughly 73% of Penumbra shares receive cash and 27% receive stock, with detailed treatment laid out for stock options and restricted stock units. The transaction, which is not subject to a financing condition, remains contingent on approval by Penumbra shareholders, antitrust and other regulatory clearances, effectiveness of Boston Scientific’s registration statement and NYSE listing approval for the new Boston Scientific shares; once completed, Penumbra’s securities will be delisted from the NYSE, and the agreement includes substantial reverse and standard termination fees tied mainly to competing bids, board recommendation changes and failure to obtain antitrust approvals. Separately, on January 15, 2026, Penumbra reported unaudited preliminary results indicating strong operational momentum for 2025, with fourth-quarter revenue of $383.0 million to $384.8 million, up about 21% to 22% year on year (over 23% excluding China), and full-year revenue of $1.401 billion to $1.403 billion, up about 17% to 18% (nearly 25% excluding China), supported by gross margins around 68% in the fourth quarter and 67% for the year and operating margins rising into the mid-teens, highlighting robust growth and profitability as the company moves toward integration with Boston Scientific.

Spark’s Take on PEN Stock
According to Spark, TipRanks’ AI Analyst, PEN is a Outperform.
Penumbra’s strong financial performance and positive earnings call are the most significant factors driving the score. The company’s robust revenue growth and improved profitability are key strengths. However, the high P/E ratio suggests potential overvaluation, and technical indicators show an overbought condition, which could pose risks.
