• Boston Scientific has agreed to acquire Penumbra (NYSE:PEN) in a cash and stock transaction valued at about $14.8 billion.
• Penumbra is expected to become a wholly owned subsidiary of Boston Scientific, with its shares delisted from the NYSE after closing.
• The deal is set to reshape the thrombectomy and neurovascular therapies space by combining Penumbra's portfolio with Boston Scientific's scale.

Penumbra enters this transaction with NYSE:PEN last closing at $358.53, backed by solid share price momentum, including a 31.0% return over the past year and 46.6% over three years. Returns of 13.5% over the past 30 days and 15.9% year to date suggest the stock has already been sensitive to company specific developments and expectations.

For current and prospective investors, the focus now shifts to what Penumbra's future as part of Boston Scientific could mean for product integration, capital allocation and competitive positioning in neurovascular and thrombectomy markets. The planned NYSE delisting also has practical implications for how you might gain or maintain exposure to Penumbra's underlying business once the transaction closes.

The agreed price of $374 per share, with roughly 73% of consideration in cash and 27% in Boston Scientific stock, effectively caps Penumbra’s recent share price momentum and converts it into a defined takeout value. For existing shareholders, the key choice is now between locking in that cash value or rolling some exposure into Boston Scientific through the stock election, subject to proration and the final deal mix.

Penumbra Narrative, Rewritten by a Takeover Premium

The acquisition directly addresses earlier concerns around Penumbra’s smaller scale, weaker free cash flow margin and capital allocation. By slotting into a much larger platform, the story shifts from whether Penumbra can fund its own growth to how its thrombectomy and neurovascular portfolio fits within Boston Scientific’s broader device offering and financing capacity.

Risks and Rewards Around the Deal

• Shareholders receive a clear liquidity event at $374 per share, which lines up with several recent analyst price targets.
• Integration into Boston Scientific may help offset Penumbra’s previous constraints around scale, distribution reach and funding larger projects.
• The transaction is subject to antitrust and shareholder approvals, so timing and closing are not fully in investors’ control.
• Boston Scientific is funding about $11b of cash consideration with existing cash and new debt, which could influence how the combined business prioritizes investment and returns.
