Subject: HPE Announces Intent to Acquire Juniper Networks

Greetings INSERT,

I hope you had a wonderful holiday season. We have some big market changing news to kick off 2024. Today at 2:30 PM PST, HPE announced their intent to acquire Juniper Networks. As you know, Juniper has been recognized as a secure AI-native networking innovator and one of the fastest growing strategic vendors across the enterprise and data center markets. In addition, Juniper has a long history as a key strategic innovator and partner in the Service Provider and Cloud infrastructure markets.

By combining HPE and Juniper’s complementary portfolios, we expect to supercharge HPE’s edge-to-cloud strategy with an ability to lead in an AI-native environment based on a foundational cloud-native architecture. Together, HPE and Juniper will seek to serve customers of all sizes with a complete, secure portfolio that enables the networking architecture necessary to manage and simplify their expanding and increasingly complex business needs.

Our CEO, Rami Rahim, has posted a blog post [INSERT HYPERLINK] on our company website, which will provide additional perspective on this exciting announcement.

HPE will be hosting a press & analyst session on January 10 at 7:30 AM PST. [INSERT LINK / DETAILS]

Since day one, setting our customers up for success has been our top priority, and we’re confident that our combination with HPE will advance that mission and present an opportunity to take our strategy to even greater heights as we look to provide continued exceptional user and operator experiences.

The transaction is currently expected to close in late calendar year 2024 or early calendar year 2025, when Rami Rahim will be the new head of HPE networking reporting to Antonio Neri, HPE’s CEO. In the meantime, Juniper will continue to compete in the marketplace and operate as usual, and we are focused on serving our customers with the same level of commitment and trust as we always have. Should you have any questions or concerns, please feel free to contact your usual Juniper’s contact.

Thank you for all your partnership and support.

Best Regards,

Cautionary Statement Regarding Forward-Looking Statements

This document contains “forward-looking statements” within the meaning of the federal securities laws, including safe harbor provisions of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements involve risks, uncertainties and assumptions and are based on Juniper’s current expectations, estimates, projections, beliefs and assumptions made by Juniper, all of which are subject to change. In this context, forward-looking statements often address expected future business, financial performance and financial condition, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “could,” “seek,” “see,” “will,” “may,” “would,” “might,” “potentially,” “estimate,” “continue,” “expect,” “target,” and similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. All forward-looking statements by their nature address matters that involve risks and uncertainties, many of which are beyond Juniper’s control, and are not guarantees of future results. These and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements and you should not place undue reliance on any such statements, and caution must be exercised in relying on forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: (i) the completion of the proposed transaction on anticipated terms and timing or at all, including obtaining stockholder and regulatory approvals and other conditions to the completion of the transaction; (ii) the ability of HPE to integrate and implement its plans, forecasts and other expectations with respect to Juniper’s business after the completion of the proposed transaction and realize additional opportunities for growth and innovation; (iii) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the merger agreement; (iv) Juniper’s ability to implement its business strategies; (v) potential significant transaction costs associated with the proposed transaction; (vi) the risks related to HPE’s financing of the proposed transaction, (vii) potential litigation or regulatory actions relating to the proposed transaction; (viii) the risk that disruptions from the proposed transaction will harm Juniper’s business, including current plans and operations, and risks related to diverting management’s attention from Juniper’s ongoing business operations and relationships; (ix) the ability of Juniper to retain and hire key personnel; (x) potential adverse business uncertainty resulting from the announcement, pendency or completion of the proposed transaction, including restrictions during the pendency of the proposed transaction that may impact Juniper’s ability to pursue certain business opportunities or strategic transactions; (xi) legal, regulatory, tax and economic developments affecting Juniper’s business; (xii) the unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism, outbreak of war or hostilities or current or future pandemics or epidemics, as well as Juniper’s response to any of the aforementioned factors; and (xiii) other risks described in Juniper’s Annual Report on Form 10-K for its fiscal year ended December 31, 2022, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings made by Juniper from time to time with the SEC. These risks should not be considered a complete statement of all potential risks and uncertainty, and are discussed more fully, along with other risks associated with the proposed transaction, in the Proxy Statement to be filed with the SEC in connection with the proposed transaction. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Juniper does not assume any obligation to publicly provide revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.
