Bernard Charlès, Dassault Systèmes' Vice Chairman and Chief Executive Officer commented, "We see a global Industry Renaissance: companies across all industries are reinventing themselves to provide new categories of experiences revealing new categories of customers. In all sectors that we serve – starting with Transportation and Mobility, Aerospace and Defense and Energy, Processes and Utilities – we observe a radical transformation of the offer. All businesses are putting their next generation portfolio at the top of their agenda.

This long term trend is going to accelerate with the ‘platform factor'. Indeed, producing new experiences requires excellence in operations and high added value ecosystems. With the 3DEXPERIENCE platform we provide an operating system – for customers to power industry solutions - and a business model – for customers to power their value networks. Moreover, the 3DEXPERIENCE platform on the Cloud enables companies to very quickly launch and create full digital continuity from day 1, as we see both in our commercial business and in our 3DEXPERIENCE Lab, our accelerator for start-ups.

"This will drive sustainable growth opportunities for 2018 and the medium term."

Nine Months Financial Summary
(Unaudited)

Nine Months 2018 versus 2017 Financial Comparisons on an IAS 18 Basis
("IAS 18 IFRS and IAS 18 non-IFRS")

• On an IAS 18 basis and in constant currencies, total revenue grew 9% (IFRS and non-IFRS) with acquisitions contributing three points to the year over year total revenue growth.

Business Outlook
(Discussion on an IAS 18, non-IFRS basis, with revenue growth rates in constant currencies)

Pascal Daloz, Dassault Systèmes' Executive Vice President, CFO and Corporate Strategy Officer, commented, "Based on our solid first half and third quarter aligned with our objectives, year-to-date total revenue and software revenue are higher by 9% at constant currency, our operating margin is stable year on year thanks to underlying operational improvements of 100 basis points enabling us to absorb 70 basis points of dilution from acquisitions as well as negative currency effects. Finally, our earnings per share is up double-digits. Our cash flow from operations increased 11% year over year, reaching €747 million for the first nine months of 2018.

"Turning to the fourth quarter, we are expecting to report another quarter of solid year over year progression, with a total revenue objective of about €1 billion and earnings per share reaching about €1.00. Given the record high quarter we reported for new licenses and other software revenue in the 2017 fourth quarter, we believe these objectives demonstrate very clearly the market opportunity before us. (all figures on an IAS non-IFRS basis)

"Finally, looking to the full year, we are confirming our non-IFRS total revenue growth objective of about 9% to 10% in constant currencies. Based upon our performance to date and fourth quarter outlook, this translates to a target revenue range of €3.425 to €3.450 billion, an operating margin of about 31.5% and EPS of about €2.98 to €3.02, representing growth of 11% to 13% or 16% to 17% at constant currency." (all figures and related growth rates on an IAS 18 non-IFRS basis)

The Company's fourth quarter and full year 2018 financial objectives presented below are given in IAS 18 on a non-IFRS basis:

• Fourth quarter 2018 Financial Objectives
  • 2018 IAS 18 non-IFRS total revenue objective of about €982 million to €1.00 billion based upon the exchange rates assumptions below, growing about 9% to 11% in constant currencies; IAS 18 non-IFRS operating margin of about 36.5%; IAS 18 non-IFRS EPS of about €0.96 to €1.00, representing growth of 8% to 12%;
• Full year 2018 Financial Objectives
  • 2018 IAS 18 non-IFRS revenue growth objective of about 9% to 10% in constant currencies reaffirmed, and updating reported revenue range to about €3.425 to €3.450 billion. The reported revenue range reflects the principal 2018 currency exchange rate assumptions below for the US dollar and Japanese yen as well as the potential impact from additional currencies representing about 17% of the Company's total revenue in 2017;
  • 2018 IAS 18 non-IFRS operating margin of about 31.5%;
  • 2018 IAS 18 non-IFRS EPS of about €2.98 to 3.02, representing a growth objective of about 11% to 13% as reported;
• Financial objectives are based upon fourth quarter exchange rate assumptions of US$1.20 per €1.00; and JPY135 per €1.00 before hedging.

These objectives are prepared and communicated only on a non-IFRS basis and are subject to the cautionary statement set forth below.

The 2018 non-IFRS objectives, which are stated on an IAS 18 basis, set forth above do not take into account the following accounting elements and are estimated based upon the 2018 principal currency exchange rates above: deferred revenue write-downs estimated at approximately €14 million on an IAS 18 basis, share-based compensation expense, including related social charges, estimated at approximately €129 million and amortization of acquired intangibles estimated at approximately €171 million. The above objectives also do not include any impact from other operating income and expense, net principally comprised of acquisition, integration and restructuring expenses, from one-time items included in financial revenue and from one-time tax restructuring gains and losses. Finally, these estimates do not include any new stock option or share grants, or any new acquisitions or restructurings completed after October 24, 2018.

Cash Flow and Other Financial Highlights Under IAS 18 For Year-over-Year Comparisons

The Company's net cash flow from operations for the three and nine months ended September 30, 2018 are identical under IFRS 15 in comparison to IAS 18 although some of the line items differ. (See pages 16 and 22 in the Appendix to this press release for further details including a reconciliation of the cash flow statement and balance sheets under IFRS 15 compared to IAS 18 for the quarter, year-to-date and period ended September 30, 2018.)

IAS 18 net operating cash flow increased 11% to €746.6 million for the first nine months of 2018 compared to €671.8 million in the 2017 period principally reflecting growth in net income and non-cash operating adjustments.

Dassault Systèmes' uses of cash for the 2018 nine-month period were principally for payment for acquisitions, net of cash acquired and non-controlling interests totaling €348.8 million; cash dividends of €38.0 million (based on the shareholders electing payment of the dividend in cash); share repurchases of €113.9 million and capital expenditures, net of €48.2 million. The Company received cash for stock options exercised of €59.2 million.

The Company's net financial position totaled €1.75 billion at September 30, 2018, compared to €1.46 billion at December 31, 2017, reflecting cash, cash equivalents and short-term investments of €2.75 billion and debt related to credit lines of €1.0 billion.

Fourth Quarter 2018 Earnings: February 6, 2019

Forward-looking Information

Statements herein that are not historical facts but express expectations or objectives for the future, including but not limited to statements regarding the Company's non-IFRS financial performance objectives, are forward-looking statements. Such forward-looking statements are based on Dassault Systèmes management's current views and assumptions and involve known and unknown risks and uncertainties. Actual results or performances may differ materially from those in such statements due to a range of factors. The Company's current outlook for 2018 takes into consideration, among other things, an uncertain global economic environment. In light of the continuing uncertainties regarding economic, business, social and geopolitical conditions at the global level, the Company's revenue, net earnings and cash flows may grow more slowly, whether on an annual or quarterly basis. While the Company makes every effort to take into consideration this uncertain macroeconomic outlook, the Company's business results, however, may not develop as anticipated. Further, there may be a substantial time lag between an improvement in global economic and business conditions and an upswing in the Company's business results. The Company's actual results or performance may also be materially negatively affected by numerous risks and uncertainties, as described in the "Risk Factors" section of the 2017 Document de Référence (Annual Report) filed with the AMF (French Financial Markets Authority) on March 21, 2018 and also available on the Company's website www.3ds.com.

In preparing such forward-looking statements, the Company has in particular assumed an average US dollar to euro exchange rate of US$1.20 per €1.00 for the 2018 fourth quarter as well as an average Japanese yen to euro exchange rate of JPY135 to €1.00 for the 2018 fourth quarter before hedging; however, currency values fluctuate, and the Company's results of operations may be significantly affected by changes in exchange rates.

Information in Constant Currencies

We have followed a long-standing policy of measuring our revenue performance and setting our revenue objectives exclusive of currency in order to measure in a transparent manner the underlying level of improvement in our total revenue and software revenue by type, industry, region and product lines. We believe it is helpful to evaluate our growth exclusive of currency impacts, particularly to help understand revenue trends in our business. Therefore, we provide percentage increases or decreases in our revenue and EPS (in both IFRS as well as non-IFRS) to eliminate the effect of changes in currency values, particularly the U.S. dollar and the Japanese yen, relative to the euro. When trend information is expressed by us "in constant currencies", the results of the "prior" period have first been recalculated using the average exchange rates of the comparable period in the current year, and then compared with the results of the comparable period in the current year.

While constant currency calculations are not considered to be an IFRS measure, we do believe these measures are critical to understanding our global revenue results and to compare with many of our competitors who report their financial results in U.S. dollars. Therefore, we are including this calculation for comparing IFRS revenue figures for comparable periods as well as for comparing non-IFRS revenue figures for comparable periods. All constant currency information is provided on an approximate basis. Unless otherwise indicated, the impact of exchange rate fluctuations is approximately the same for both the Company's IFRS and supplemental non-IFRS financial data.

Information on Growth excluding acquisitions ("organic growth")

In addition to discussing total growth, we also provide financial information where we discuss growth excluding acquisitions or growth on an organic basis as used alternatively. In both cases, growth excluding acquisitions have been calculated using the following restatements of the scope of consolidation: for entities entering the consolidation scope in the current year, subtracting the contribution of the acquisition from the aggregates of the current year, and for entities entering the consolidation scope in the previous year, subtracting the contribution of the acquisition from January 1st of the current year, until the last day of the month of the current year when the acquisition was made the previous year.

Information on Industrial Sectors

The Company's global customer base includes companies in 12 industrial sectors: Transportation & Mobility; Industrial Equipment; Aerospace & Defense; Financial & Business Services; High-Tech; Life Sciences; Energy, Process & Utilities; Consumer Goods & Retail; Natural Resources; Architecture, Engineering & Construction; Consumer Packaged Goods & Retail and Marine & Offshore. Commencing in 2012 we implemented an industry go-to-market strategy with the dual objectives of broadening and deepening our presence in our largest industries as well as increasing the contribution from a diversified set of industrial sectors. "Diversification Industries" include: Architecture, Engineering & Construction; Consumer Goods & Retail; Consumer Packaged Goods & Retail; Energy, Process & Utilities; Finance Business Services; High-Tech; Life Sciences; Marine & Offshore; and Natural Resources. "Core Industries" include: Transportation & Mobility, Industrial Equipment, Aerospace & Defense and a portion of Business Services.

3DEXPERIENCE Licenses and Software Contribution

To measure the progressive penetration of 3DEXPERIENCE software, the Company utilizes the following ratios: a) for Licenses revenue, the Company calculates the percentage contribution by comparing total 3DEXPERIENCE Licenses revenue to Licenses revenue for all product lines except SOLIDWORKS and acquisitions ("related Licenses revenue"); and, b) for software revenue, the Company calculates the percentage contribution by comparing total 3DEXPERIENCE software revenue to software revenue for all product lines except SOLIDWORKS and acquisitions ("related software revenue").

Summary of Principal Differences of IFRS 15 Compared to IAS 18

The Company has adopted IFRS 15 as of January 1, 2018 using the modified retrospective transition method (also called the cumulative effect method). Under this method, the transition effect is accounted for within the consolidated equity at the date of initial application, i.e. January 1, 2018, without any adjustment to the prior year comparative information. See also the Company's 2017 Document de Référence (Annual Report) for further information.

• Recurring software: Recurring software is comprised of subscription and support revenue. IFRS 15 has an impact on the timing of the quarterly recognition of subscription revenue but on a full year basis there is essentially no difference between IFRS 15 and the prior IAS 18 standard for subscription contracts of one year in length. For the 2018 3^rd quarter, IFRS recurring software revenue was €523.2 million under IFRS 15 and was €22.1 million less compared to the prior IAS 18 standard. Previously, under IAS 18, we showed a ratable quarterly amount based upon the annual contract level of our on-premise subscription software. Under IFRS 15, for new contracts entered into or for contracts renewing, we have assigned an upfront value as required which is recognized in the first quarter of the contract, and the remainder which is recognized ratably during the four quarters. We continue to report both of these amounts within recurring revenue, specifically as subscription revenue (previously called periodic revenue).
• Operating expenses and sales commissions: The Company continues to expense sales commissions under the IFRS 15 standard as was done under IAS 18. Therefore, there are no capitalized sales commissions. As a result, the Company's operating expenses are identical under IFRS 15 and the prior IAS 18 standard.
• One-time permanent difference: The implementation of IFRS 15 on January 1, 2018 resulted in a one-time permanent difference between IFRS 15 and IAS 18, where the deferred portion of subscription agreements concluded in prior years will not be recognized into revenue. As a result, the corresponding amount of €80 million, net of taxes (€110 million before) was recorded in stockholders' equity as of January 1, 2018.
• Initial impact on unearned revenue: At September 30, 2018 unearned revenue on the Balance Sheet under IFRS 15 is not directly comparable to the December 31, 2017 balance sheet under the prior standard IAS 18. This is due to the fact that the September 30, 2018 balance sheet line item unearned revenue has been reduced by €110 million, reflecting mainly (i) the one-time permanent difference of €94 million, and (ii) the higher amount of revenue recognized in the first nine months under IFRS 15 compared to IAS 18 in the amount of €17 million.
• Contract Assets: Under IFRS 15, the Company classifies the right to consideration in exchange for products or services transferred to a client as either a receivable or a contract asset. Contract assets amounted to €32 million as at January 1, 2018 (1^st application impact) and to €38 million as at September 30, 2018.
