Insights

Boston Scientific moves to acquire Penumbra, with closing still conditional.

Boston Scientific has signed a definitive agreement to acquire Penumbra through a merger structure involving a wholly owned subsidiary. This signals an expansion move, but the excerpt does not provide purchase price, consideration mix, or expected financial contribution, so investors must look to the press release and upcoming S-4 filing for detailed economics.

The transaction is explicitly subject to regulatory approvals, other closing conditions, and successful post‑closing integration of Penumbra’s operations. The text highlights risks such as potential business disruptions, clinical and market uncertainties, macroeconomic conditions, and the chance that the deal may be delayed or may not close. The planned Form S‑4 with a proxy statement/prospectus will be the key document for Penumbra stockholders when evaluating the proposal.

The information in Item 7.01 of this Current Report on Form 8-K, as well as Exhibit 99.1 and Exhibit 99.2 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K and the information incorporated by reference herein contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements may be identified by words like “anticipate,” “expect,” “project,” “believe,” “plan,” “estimate,” “intend” and similar words. These forward-looking statements are based on our beliefs, assumptions and estimates using information available to us at the time and are not intended to be guarantees of future events or performance. These forward-looking statements include, among other things, statements regarding the financial and business impact of the Transaction and anticipated benefits of the Transaction, the closing of the Transaction and the timing thereof, business plans and strategy, product launches and product performance and impact, clinical programs, and expected financial results. If our underlying assumptions turn out to be incorrect, or if certain risks or uncertainties materialize, actual results could vary materially from the expectations and projections expressed or implied by our forward-looking statements. These factors, in some cases, have affected and in the future (together with other factors) could affect our ability to implement our business strategy and may cause actual results to differ materially from those contemplated by the statements expressed in this Current Report on Form 8-K. As a result, readers are cautioned not to place undue reliance on any of our forward-looking statements.

Factors that may cause such differences include, among other things: economic conditions, including the impact of foreign currency fluctuations; future U.S. and global political, competitive, reimbursement and regulatory conditions, including changing trade and tariff policies; geopolitical events; manufacturing, distribution and supply chain disruptions and cost increases; disruptions caused by cybersecurity events; disruptions caused by public health emergencies or extreme weather or other climate change-related events; labor shortages and increases in labor costs; variations in outcomes of ongoing and future clinical trials and market studies; new product introductions; expected procedural volumes; the closing and integration of acquisitions, including the ability to achieve the anticipated benefits of the proposed transaction and successfully integrate Penumbra’s operations; business disruptions (including disruptions in relationships with employees, customers or suppliers) following the announcement and/or closing of the proposed Transaction; demographic trends; intellectual property; litigation; financial market conditions; future business decisions made by us and our competitors; the conditions to the completion of the proposed Transaction, including the receipt of the required regulatory approvals and clearances, may not be satisfied at all or in a timely manner; and the closing of the proposed Transaction may not occur or may be delayed. All of these factors are difficult or impossible to predict accurately and many of them are beyond our control. For a further list and description of these and other important risks and uncertainties that may affect each of the Company’s and Penumbra’s businesses and future operations, see Part I, Item 1A – Risk Factors in the Company’s and Penumbra’s respective most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, which may be updated in Part II, Item 1A – Risk Factors in Quarterly Reports on Form 10-Q each company has filed or will file hereafter.

 

 

 

 
 

 

The Company disclaims any intention or obligation to publicly update or revise any forward-looking statements to reflect any change in our expectations or in events, conditions or circumstances on which those expectations may be based, or that may affect the likelihood that actual results will differ from those contained in the forward-looking statements, except as required by law. This cautionary statement is applicable to all forward-looking statements contained in this Current Report on Form 8-K.
