Tempe, Arizona, May 8, 2018 (Businesswire) - Versum Materials, Inc. (NYSE: VSM), a leading global materials and equipment supplier to the semiconductor industry, today reported results for the fiscal second quarter ended March 31, 2018. Sales of $340.7 million were up26% from the fiscal second quarter ended March 31, 2017, driven primarily by robust growth from our Delivery Systems & Services ("DS&S") segment and our Advanced Materials product lines. Net income for the fiscal second quarter ended March 31, 2018 was $61.6 million, or $0.56 per diluted share, up$16.7 million from the fiscal second quarter ended March 31, 2017, resulting in Net Income Margin of 18%. Excluding a reduction to the previous charge associated with the US Tax Cuts and Jobs Act ("Tax Act") and one-time charges related to separation, restructuring and cost reduction actions, Adjusted Net Income of $64.7 million or $0.59 per diluted share, increased 35% from the fiscal second quarter ended March 31, 2017 and resulted in an Adjusted Net Income Margin of 19%. Adjusted EBITDA of $109.9 million increased 26% from the fiscal second quarter ended March 31, 2017, resulting in an Adjusted EBITDA margin of 32%.

Guillermo Novo, Versum Materials' President and Chief Executive Officer said “We are pleased to report strong results for our fiscal second quarter, which was highlighted by share gains leading to robust top line growth in both our Materials and DS&S segments. Materials volume grew double digits which underscores our ability to provide innovative solutions to customers through technology. Our focused offerings and positioning with key customers enabled us to enjoy growth in our DS&S segment which far outpaced the market."

"Going live on our own ERP system was a watershed moment for our Company, as it substantially marked the completion of our transition to a standalone entity. I am very thankful to our entire team who diligently worked to reach this milestone, and we are encouraged by its early success. Looking forward we are excited to focus on executing the growth opportunities in front of us, and we are encouraged by our new business pipeline that has enabled us to increase our outlook for 2018.”

Sales for the fiscal second quarter ended March 31, 2018 were $340.7 million versus $270.8 million in the fiscal second quarter ended March 31, 2017. This 26% year on year increase was attributable to robust growth in our DS&S segment and double-digit volume growth in Materials partially offset by unfavorable price/mix.

Net Income for the fiscal second quarter ended March 31, 2018 was $61.6 million, or $0.56per diluted share versus $44.9 million, or $0.41 per diluted share, in the fiscal second quarter ended March 31, 2017, a 37%increase. This increase is a result of strong sales volumes and favorable operating cost performance. Excluding a $3.7 million reduction to the previous provisional charge for the cost of the deemed repatriation tax associated with the Tax Act and the one-time charges of $6.8 million related to separation, restructuring and cost reduction actions, Adjusted Net Income for the fiscal second quarter ended March 31, 2018 was $64.7 million, or $0.59 per diluted share, versus $47.9 million, or $0.44 per diluted share, for the fiscal second quarter ended March 31, 2017.

Adjusted EBITDA for the fiscal second quarter ended March 31, 2018 was $109.9 million versus $86.9 million in the fiscal second quarter ended March 31, 2017, a 26%increase year on year. Strong volumes in both DS&S and Materials coupled with modestly favorable currency were partially offset by unfavorable gross profit impacts and higher Selling and Administrative and Research & Development (SARD) costs to support growth.

Year to date cash flow from operations was $56.5 million, with cash invested for capital spending of $65.1 million, including $26.7 million of capital spending related to restructuring activities. Cash outflows for restructuring, vendor prepayments made in advance of our SAP go-live and payables timing resulted in lower cash flow in the first half of the fiscal year, as expected.

Materials:

Sales for the fiscal second quarter ended March 31, 2018 were $218.9 million, up10% from the fiscal second quarter ended March 31, 2017. This increase was driven by double digit volume growth partially offset by unfavorable price/mix. Currency contributed 2% to the increase.

Operating income for the fiscal second quarter ended March 31, 2018 was $71.6 million, up10% from the fiscal second quarter ended March 31, 2017. Segment Adjusted EBITDA for the fiscal second quarter ended March 31, 2018 was $83.2 million, up11% from the fiscal second quarter ended March 31, 2017. Strong Advanced Materials performance was partially offset by Process Materials carryover pricing and mix. Segment SARD costs were higher primarily to support our growth objectives in Asia and costs associated with completing our separation.

Delivery Systems & Services (DS&S):

Sales for the fiscal second quarter ended March 31, 2018 were $121.1 million, up69% from the fiscal second quarter ended March 31, 2017, driven by continued strong equipment and installation project growth due to robust demand across all markets especially Korea and China.

Operating income for the fiscal second quarter ended March 31, 2018 was $32.9 million, up86% from the fiscal second quarter ended March 31, 2017. Segment Adjusted EBITDA of $33.3 million was up84%, driven by the robust equipment and installation activity.

Fiscal Year 2018 Outlook

Regarding the rest of the year, Guillermo Novo added, “The continued strong semiconductor market and improved industry capital spending forecast, combined with our position with key customers provides a favorable outlook for the remainder of the year. We expect Materials margin to continue to improve, DS&S activity to remain strong through the remainder of the year and successful completion of various capital projects which will drive future profitable growth.”

For fiscal year 2018, Versum Materials is revising its outlook to estimated sales of $1,320 to $1,360 million and Adjusted EBITDA of $425 to $445 million from prior guidance of $1,250 to $1,300 million and $415 to $435 million, respectively. The fiscal year 2018 Adjusted EBITDA outlook excludes approximately $15 to $20 million of estimated one-time stand-up costs related to the implementation of our own enterprise resource planning (ERP) system and relocation of certain administrative and research and development personnel to Versum Materials sites.

Non-GAAP Financial Measures

This earnings press release includes “non-GAAP financial measures,” including Adjusted Net Income, Adjusted Net Income Margin, Adjusted Diluted Earnings Per Share, Adjusted EBITDA, Segment Adjusted EBITDA, Adjusted EBITDA margin and Segment Adjusted EBITDA margin. Adjusted Net Income is net income excluding certain disclosed items which we do not believe to be indicative of underlying business trends, including business separation, restructuring and cost reduction actions, net of tax, the write-off of financing costs, net of tax, and the impact of the Tax Act. Adjusted Diluted Earnings Per Share uses Adjusted Net Income but otherwise uses the same calculation used in arriving at diluted earnings per share, the most directly comparable GAAP financial measure. Adjusted EBITDA is net income excluding certain disclosed items which we do not believe to be indicative of underlying business trends, including interest expense, the write-off of financing costs, income tax provision, depreciation and amortization expense, non-controlling interests, and business separation, restructuring and cost reduction actions. Segment Adjusted EBITDA is segment operating income excluding segment depreciation and amortization expense. Adjusted Net Income Margin, Adjusted EBITDA margin and Segment Adjusted EBITDA margin are calculated by dividing Adjusted Net Income, Adjusted EBITDA and Segment Adjusted EBITDA, respectively, by sales. In the accompanying tables, Versum Materials has provided reconciliations of net income to Adjusted EBITDA (see Appendix Table A-2), net income to Adjusted Net Income (see Appendix Table A-3), diluted EPS to Adjusted Diluted EPS (see Appendix A-4) and of segment operating income (loss) to Segment Adjusted EBITDA (see Appendix Table A-6), in each case the most directly comparable GAAP financial measure. We encourage investors to read these reconciliations.

The presentation of these non-GAAP financial measures is intended to enhance the usefulness of financial information by providing measures which management uses internally to evaluate operating performance. We use these non-GAAP measures to assess our operating performance by excluding certain disclosed items that we believe are not representative of our underlying business. Management may use these non-GAAP measures to evaluate our performance period over period and relative to competitors in our industry, to analyze underlying trends in our business and to establish operational budgets and forecasts or for incentive compensation purposes. We use Adjusted EBITDA to calculate performance-based cash bonuses. Adjusted EBITDA is also used for certain covenants under our senior secured credit facilities. We use Segment Adjusted EBITDA to evaluate the ongoing performance of our business segments.

We believe non-GAAP financial measures provide security analysts, investors and other interested parties with meaningful information to understand our underlying operating results and to analyze financial and business trends. These non-GAAP financial measures should not be viewed in isolation, are not a substitute for GAAP measures, and have limitations which include but are not limited to the following: (a) Adjusted Net Income and Adjusted EBITDA exclude the write-off of financing costs and other expenses related to business separation, restructuring and cost reduction actions which we do not consider to be representative of our underlying business operations, however, these disclosed items represent costs to Versum Materials; (b) Adjusted EBITDA is not intended to be a measure of cash available for management’s discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements; (c) though not business operating costs, interest expense and income tax provision represent ongoing costs of Versum Materials; (d) depreciation and amortization charges represent the wear and tear or reduction in value of the plant, equipment, and intangible assets which permit us to manufacture and market our products; and (e) other companies may define non-GAAP measures differently than we do, limiting their usefulness as comparative measures. A reader may find any one or all of these items important in evaluating our performance. Management compensates for the limitations of using non-GAAP financial measures by using them only to supplement our GAAP results and to provide a more complete understanding

Page | 5

of the factors and trends affecting our business. In evaluating these non-GAAP financial measures, the reader should be aware that we may incur expenses similar to those eliminated in this presentation in the future.

A reconciliation of net income to Adjusted EBITDA as forecasted for 2018 is not provided. Versum Materials does not forecast net income as it cannot, without unreasonable effort, estimate or predict with certainty various components of net income. These components include further restructuring and other income or charges to be incurred in 2018 as well as the related tax impacts of these items. Additionally, discrete tax items could drive variability in our forecasted effective tax rate. All of these components could significantly impact net income. Further, in the future, other items with similar characteristics to those currently included in Adjusted EBITDA that have a similar impact on comparability of periods, and which are not known at this time, may exist and impact Adjusted EBITDA.
