VAR Varian Medical System

As previously announced, on August 2, 2020, Varian Medical Systems, Inc., a Delaware corporation (“Varian”), Siemens Healthineers Holding I GmbH, a company organized under the laws of Germany (“Parent”), Falcon Sub Inc., a Delaware corporation and a direct wholly-owned subsidiary of Parent (“Merger Sub”), and, with respect to certain provisions, Siemens Medical Solutions USA, Inc., a Delaware corporation (the “Guarantor”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other things, Merger Sub will be merged with and into Varian (the “Merger”), with Varian surviving the Merger as a wholly owned subsidiary of Parent. In connection with the Merger Agreement, on September 14, 2020, Varian filed a definitive proxy statement (the “Proxy Statement”) with the U.S. Securities and Exchange Commission (the “SEC”).

As previously disclosed in the Proxy Statement, as of September 11, 2020, three lawsuits (collectively, the “Actions”), including two purported class action lawsuits, have been filed by purported Varian stockholders in connection with the Merger. On August 31, 2020, a purported Varian stockholder filed a lawsuit against Varian and the members of Varian’s board of directors alleging that the Proxy Statement contained alleged material misstatements and/or omissions in violation of federal law. The lawsuit is captioned Stein v. Varian Medical Systems, Inc., et al., Case 3:20-cv-6140 and is pending in the United States District Court for the Northern District of California. On September 3, 2020, two purported class action lawsuits were filed against the same defendants by purported Varian stockholders asserting similar claims: Kent v. Varian Medical Systems, Inc., et al., Case 1:20-cv-1178, pending in the United States District Court for the District of Delaware, and Zimmer v. Varian Medical Systems, Inc., et al., Case 4:20-cv-6266, pending in the United States District Court for the Northern District of California.

The complaints generally allege that the Proxy Statement filed by Varian in connection with the Merger fails to disclose allegedly material information in violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 and Rule 14a-9 promulgated thereunder. The alleged omissions relate to (i) certain financial projections of Varian, and (ii) certain financial analyses of Varian’s financial advisor. Plaintiffs seek, among other things, to enjoin Varian from consummating the Merger, or in the alternative, rescission of the Merger and/or compensatory damages.

While Varian believes that no supplemental disclosures are required under applicable laws, to reduce the costs, risks and uncertainties inherent in litigation, on October 5, 2020, Varian reached an agreement to resolve the Actions in exchange for voluntarily making certain disclosures below that supplement and revise those contained in the Proxy Statement. Plaintiffs in the Actions have agreed that, following the filing of this 8-K, they will dismiss the Actions in their entirety, with prejudice as to the named plaintiffs only and without prejudice to all other members of the putative class. Varian denies that any of the defendants have committed or assisted others in committing any violations of law. Nothing in these supplemental disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the supplemental disclosures set forth herein.

The following supplemental disclosures should be read in conjunction with the Proxy Statement, which should be read in its entirety. To the extent that information herein differs from or updates information contained in the Proxy Statement, the information contained herein supersedes the information contained in the Proxy Statement. All page references are to pages in the Proxy Statement, and defined terms used but not defined herein have the meanings set forth in the Proxy Statement. For clarity, new text within restated paragraphs (other than tables) from the Proxy Statement are highlighted with bold, underlined text.

Supplemental Disclosures

Amending and restating the last paragraph on page 48 as follows:

Illustrative Discounted Cash Flow Analysis. Using the Varian Projections, Goldman Sachs performed an illustrative discounted cash flow analysis on Varian. Using discount rates ranging from 8.00% to 9.00%, reflecting estimates of Varian’s weighted average cost of capital, Goldman Sachs discounted to present value as of July 3, 2020 (i) estimates of unlevered free cash flow for Varian for the fourth fiscal quarter of 2020 and the fiscal

years 2021 through 2030 as reflected in the Varian Projections and (ii) a range of illustrative terminal values for Varian, which were calculated by applying perpetuity growth rates ranging from 2.25% to 2.75%, to a terminal year estimate of the free cash flow to be generated by Varian, as reflected in the Varian Projections (which analysis implied exit terminal year EV / LTM EBITDA multiples ranging from 10.6x to 13.6x). Goldman Sachs derived such discount rates by application of the CAPM, which requires certain company-specific inputs, including the company’s target capital structure weightings, the cost of long-term debt, after-tax yield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for the company, as well as certain financial metrics for the United States financial markets generally. In addition, stock based compensation expense was treated as a cash expense for purposes of determining unlevered free cash flow. The range of perpetuity growth rates was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account the Varian Projections and market expectations regarding long-term real growth of gross domestic product and inflation. Goldman Sachs derived ranges of illustrative enterprise values for Varian by adding the ranges of present values it derived above. Goldman Sachs then subtracted an amount of net debt ranging from $175 to $178 million (per information provided by the management of Varian) from the range of illustrative enterprise values it derived for Varian to derive a range of illustrative equity values for Varian. Goldman Sachs then divided the range of illustrative equity values it derived by a number of fully diluted outstanding shares of Varian common stock using the treasury stock method ranging from 92.2 to 92.6 million, to derive a range of illustrative present values per share of Varian common stock ranging from $153 to $198, rounded to the nearest dollar.

Amending and restating the second paragraph from the bottom of page 49 as follows:

Premia Analysis. Goldman Sachs reviewed and analyzed, using publicly available information, the acquisition premia for 83 transactions announced since August 2015 involving a public company based in the United States as the target where the disclosed enterprise values for each transaction was greater than $10 billion. For the entire period, using publicly available information, Goldman Sachs calculated the median, 25th percentile and 75th percentile premia of the price paid in each transaction relative to the target’s last undisturbed closing stock price prior to announcement of the transaction. This analysis indicated a median premium of 27% across the period. This analysis also indicated a 25th percentile premium of 17% and a 75th percentile premium of 42% across the period. Using this analysis, Goldman Sachs applied a reference range of illustrative premia of 17% to 42% to the undisturbed closing price per share of Varian common stock of $142.72 as of July 31, 2020 and calculated a range of implied equity values per share of Varian common stock of $167 to $203, rounded to the nearest dollar.

Amending and restating the last paragraph on page 52 as follows:

The following table presents the estimated amounts of Adjusted EBIT and unlevered free cash flow of Varian, respectively, as calculated by Goldman Sachs using the Varian Projections provided by Varian management for purposes of Goldman Sachs’ financial analyses described in the section entitled “—Opinion of Varian’s Financial Advisor.” In addition, Goldman Sachs calculated an estimate of Varian’s LTM EBITDA as of July 3, 2020 of $557 million using the Varian Projections provided by Varian management for purposes of Goldman Sachs’ financial analyses described in the section entitled “—Opinion of Varian’s Financial Advisor.”
