Following that board meeting, in March 2019, Mr. Rhine separately contacted each of Mr. Plisinski and David B. Miller, the chairman of the Rudolph board of directors, by telephone to indicate that if Rudolph was interested in commencing renewed discussions regarding a potential business combination between the two companies, that interest could be communicated directly to the Nanometrics board of directors, and that Mr. Rhine believed the Nanometrics board of directors would be receptive if Rudolph did so. During Mr. Rhine’s conversation with Mr. Miller, Mr. Rhine indicated that it would likely be acceptable to the Nanometrics board of directors that Mr. Plisinski serve as the chief executive officer of the combined company, based on, among other things, Mr. Plisinski’s professional experience, knowledge of the semiconductor industry, and familiarity with both Rudolph and Nanometrics and their respective products and markets.

Under the heading “THE MERGER—Opinion of Barclays, Nanometrics’ Financial Advisor—Discounted Cash Flow Analysis,” the first full paragraph on page 108 is amended and restated as follows (with new text in bold):

To calculate the estimated enterprise value of Nanometrics using the discounted cash flow method, Barclays added (and discounted to present values using a range of selected discount rates) (i) the unlevered free cash flows for Nanometrics calculated by Barclays based on the projections by Nanometrics for the stub period from June 22, 2019 through December 31, 2019, and for the fiscal years 2020 and 2021 to (ii) the “terminal value” of Nanometrics as of December 31, 2021. Barclays used the mid-year convention in its discounted cash flow analysis to more accurately reflect the present value of future cash flows because cash flows are actually earned throughout the year rather than at the end of the year. The projected unlevered free cash flows were calculated by Barclays as the amount equal to (a) EBITDA, excluding depreciation and amortization, multiplied by (b) one minus the tax rate, subtracting (c) capital expenditures and changes in net working capital, and adding the impact of (d) depreciation, amortization, and stock based compensation, based on the Nanometrics projections and the amount of such items as set forth in the section entitled “—Nanometrics Unaudited Financial Projections” beginning on page 125 of this joint proxy statement/prospectus. Using the “perpetuity growth” method, the terminal value of Nanometrics was estimated by selecting a range of 2.0% to 4.0% of annual growth rates for Nanometrics in perpetuity after December 31, 2021,

which range was derived by Barclays utilizing its professional judgment and experience, taking into account the financial projections by Nanometrics and market expectations regarding long-term growth of gross domestic product and inflation. The range of after-tax discount rates of 11.0% to 13.0% was selected based on an analysis of the weighted average cost of capital, which is referred to as WACC, of Nanometrics and the selected comparable companies. Barclays derived its WACC range for Nanometrics by reviewing certain metrics of Nanometrics, Rudolph, and the selected companies listed in the section entitled “—Selected Comparable Company Analysis” beginning on page 106 of this joint proxy statement/prospectus, including a five-year raw historical weekly beta per Bloomberg (as of June 21, 2019), market value of debt and market value of equity, each based on market data as of June 21, 2019, total capitalization, debt to equity ratio, debt in relation to debt plus equity, cost of debt, a 21% marginal tax rate for each of Nanometrics and Rudolph, marginal tax rates for comparable companies using an assumed marginal tax rate and unlevered beta. Barclays then calculated a range of implied present value prices per share of Nanometrics common stock by subtracting estimated net debt (found by subtracting the value of Nanometrics’ cash and cash equivalents and marketable securities from the principal amount of its total debt, which is zero) as of June 20, 2019, which was an amount equal to approximately $142.4 million, as provided by Nanometrics management, from the estimated enterprise value using the discounted cash flow method and dividing such amount by the diluted number of shares of Nanometrics common stock, calculated using the treasury stock method, and using the number of shares of Nanometrics common stock, Nanometrics options, Nanometrics RSU awards, Nanometrics PRSU awards, and Nanometrics common stock subject to purchase rights under the Nanometrics Employee Stock Purchase Plan outstanding as of June 20, 2019, as indicated in the table below. For purposes of Barclays’ discounted cash flow analysis, based on information provided by Nanometrics management, Barclays assumed there were approximately 25.7 million shares of Nanometrics common stock outstanding on a fully diluted basis.

Under the heading “THE MERGER—Opinion of Barclays, Nanometrics’ Financial Advisor—Discounted Cash Flow Analysis,” the last paragraph on page 108 is amended and restated as follows (with new text in bold, and deleted text shown with a line through it):

To calculate the estimated enterprise value of Rudolph using the discounted cash flow method, Barclays added (and discounted to present using a range of selected discount rates) (i) the projected unlevered free cash flows for Rudolph calculated by Barclays for the stub period from June 21, 2019 through December 31, 2019 and for the fiscal years 2020 and 2021 based on the financial projections by Rudolph.to (ii) the “terminal value” of Rudolph as of December 31, 2021.

Barclays then calculated a range of implied present value prices per share of common stock of Rudolph by subtracting estimated net debt (found by subtracting the value of Rudolph’s cash and cash equivalents and marketable securities from the principal amount of its total debt which is zero) as of June 20, 2019, which was an amount equal to approximately $177.0 million, as provided by Rudolph management, from the estimated enterprise value using the discounted cash flow method and dividing such amount by the diluted number of shares of common stock of Rudolph, calculated using the treasury stock method, and using the number of shares of

common stock of Rudolph, Rudolph options, Rudolph RSU Awards, Rudolph PSU awards, and Rudolph common stock subject to purchase rights under the Rudolph ESPP outstanding as of June 20, 2019, as indicated in the table below. For purposes of Barclays’ discounted cash flow analysis, based on information provided by Rudolph management, Barclays assumed there were approximately 32.0 million shares of Rudolph common stock outstanding on a fully diluted basis.

Under the heading “THE MERGER—Opinion of Morgan Stanley, Rudolph’s Financial Advisor—Relative Discounted Cash Flow Analysis,” the first full paragraph on page 119 is amended and restated as follows (with new text in bold):

Morgan Stanley then estimated the terminal values of Rudolph at the end of the forecast period by using perpetual growth rates ranging from 1.0% to 3.0%, which were applied to the forecasted unlevered free cash flows of Rudolph for CY 2028. Such perpetual growth rates were selected upon the application of Morgan Stanley’s professional judgment, knowledge of the industry and experience. The cash flows and terminal values were then discounted to present value as of June 30, 2019 using discount rates ranging from 8.6% to 9.6%, which discount rates

were selected upon the application of Morgan Stanley’s professional judgment, knowledge of the industry and experience to reflect the weighted average cost of capital for Rudolph under the capital asset pricing model, which requires certain company-specific inputs, including a total debt to total capitalization ratio, a pre-tax cost of debt, a tax rate, and a beta, as well as certain financial metrics for the U.S. financial markets generally. The resulting aggregate values were then adjusted for estimated net cash as of June 30, 2019, which was an amount equal to approximately $185 million, as provided by Rudolph management. This analysis resulted in an implied per share equity value reference range for Rudolph common stock (rounded to the nearest dollar) of $53 to $72. This analysis assumed approximately 32 million fully diluted shares outstanding as of June 20, 2019, the latest date for which data was available, as calculated by Morgan Stanley based on the capitalization table provided by Rudolph management to Morgan Stanley.

Under the heading “THE MERGER—Opinion of Morgan Stanley, Rudolph’s Financial Advisor—Relative Discounted Cash Flow Analysis,” the third full paragraph on page 119 is amended and restated as follows (with new text in bold):

Such perpetual growth rates were selected upon the application of Morgan Stanley’s professional judgment, knowledge of the industry and experience. The cash flows and terminal values were then discounted to present value as of June 30, 2019 using discount rates ranging from 9.1% to 10.1%, which discount rates were selected upon the application of Morgan Stanley’s professional judgment, knowledge of the industry and experience to reflect the weighted average cost of capital for Nanometrics under the capital asset pricing model, which requires certain company-specific inputs, including a total debt to total capitalization ratio, a pre-tax cost of debt, a tax rate, and a beta, as well as certain financial metrics for the U.S. financial markets generally. The resulting aggregate values were then adjusted for estimated net cash as of June 30, 2019, which was an amount equal to approximately $149 million, as provided by Nanometrics management. This analysis resulted in an implied per share equity value reference range for Nanometrics common stock (rounded to the nearest dollar) of $72 to $101. This analysis assumed approximately 26 million fully diluted shares outstanding as of June 20, 2019, the latest date for which data was available, as calculated by Morgan Stanley based on the capitalization table provided by Nanometrics management to Morgan Stanley.

Morgan Stanley reviewed future public market trading price targets for Rudolph common stock and Nanometrics common stock prepared and published by the five research analysts reporting price targets per Capital IQ for each of Rudolph and Nanometrics as of June 21, 2019 (the last full trading day prior to the meeting of the Rudolph board of directors to adopt the merger agreement and approve the transactions contemplated thereby, including the merger). These forward targets reflected each analyst’s estimate of the 12-month future public market trading price of Rudolph common stock and Nanometrics common stock. The analyst price targets for Rudolph were $32.00, $31.00, $30.00, $28.50, and $23.00 per share as of June 21, 2019, as reported by Capital IQ. The analyst price targets for Nanometrics were $42.00, $41.00, $40.00, $40.00, and $39.00 per share as of June 21, 2019, as reported by Capital IQ. Morgan Stanley also discounted such 12-month future market trading price estimates by the mid-point cost of equity for Rudolph (9.1%) and Nanometrics (9.6%), respectively, as calculated under the capital asset pricing model.
