TALEND INVESTOR PRESENTATION JUNE 25, 2019 ANNUAL COMBINED GENERAL MEETING SHAREHOLDERS’ 1

This presentation and the accompanying oral presentation contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements generally relate to future events or our future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions. Forward-looking statements in this presentation include, but are not limited to, our expectations with respect to the acquisition of Stitch and regarding the future demand and behavior of customers and the data integration market, our expectations regarding the evolution of our marketplace and our ability to capture an increasing share of the big data and cloud integration market. Our expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to inherent risks, uncertainties and changes in circumstance that are difficult or impossible to predict. Consequently, you should not rely on these forward-looking statements. Actual outcomes and results may differ materially from those contemplated by these forward-looking statements as a result of such uncertainties, risks, and changes in circumstances. Those risks, uncertainties and assumptions include our operating results and business generally; our ability to retain existing customers and generate new customers; the market for data integration solutions, particularly our big data and cloud integration solutions, not continuing to develop; our expectations regarding our strategic product initiatives and their related benefits; our ability to achieve our plans, forecasts and other expectations with respect to Stitch's business after the recent acquisition of the Stitch business; competition from other products and services; and general market, political, economic and business conditions, including the fluctuation of foreign currency exchange rates. The forward-looking statements contained in this presentation are also subject to other risks and uncertainties, and the foregoing list of factors is not exclusive. Additional risks and uncertainties that could affect our financial and operating results are included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation” and elsewhere in our most recent filings with the Securities and Exchange Commission, including our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2019 and any subsequent reports on Form 10-K, Form 10-Q or Form 8-K filed with the SEC. Our SEC filings are available on the Investors section of Talend’s website at http://investor.talend.com and the SEC’s website at www.sec.gov. The forward-looking statements in this presentation are based on information available to us as of the date hereof, and we disclaim any obligation to update any forward-looking statements provided to reflect any change in our expectations or any change in events, conditions, or circumstances on which any such statement is based, except as required by law. This presentation also contains estimates and other statistical data made by independent parties and by the Company relating to market size and growth and other industry data. These data involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. The Company has not independently verified the statistical and other industry data generated by independent parties and contained in this presentation and, accordingly, it cannot guarantee their accuracy or completeness. In addition, projections, assumptions and estimates of its future performance and the future performance of the industries in which it operates are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by Talend. As previously announced, effective January 1, 2019, we began to file periodic reports and registration statements on U.S. domestic issuer forms with the Securities and Exchange Commission. Accordingly, the financial results and estimates discussed herein have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). 2

1 TALEND EQUITY COMPENSATION PRINCIPLES Key considerations in determining requested grant amounts 12 12 • Ability to attract and retain world-class talent with market competitive offers • Policies and plan consistent with 2018. Current share pool: – 30,359,600 shares outstanding as of March 31, 2019 – 2,000,000 total shares available for issuance under proposed resolutions; same as in 2018 – Approx. 6.59% of shares outstanding at March 31, 2019 – In 2018, 1,107,987 shares were granted to 783 individuals (including 380 new hires) • Overhang (options, warrants, and RSUs issued) – 1,861,626 shares subject to outstanding options and warrants at March 31, 2019 – Average remaining term 6.2 years; weighted average exercise price $13.14/share – 2,033,156 outstanding free shares (RSUs) as of March 31, 2019

1 EQUITY COMPENSATION PRACTICES (CONT.) Equity Program Best Practices for Compensation and Corporate Governance Additional Considerations and Clarifications 13 13 •Annual bonus plan payout limits are set forth in our Definitive Proxy Statement for NEOs at 100% of Base Salary: Michael Tuchen, 55% of Base Salary for Adam Meister, and 33% of Base Salary for Laurent Bride.1 •PSU grants limited to Company executives; 2019 performance metrics based 100% on Cloud ARR, our most important long-term value driver •No Annual Evergreen. No automatic yearly increase in shares available for issuance. •No Liberal Share Recounting. Expired/canceled shares not available for future grants. •Minimum Vesting Requirements. No vesting commencement before one year from grant date; RSU awards typically have four-year vesting term. •Limited Transferability; Holding Periods. Awards generally may not be sold or otherwise transferred; shares acquired may not be sold or transferred before second anniversary of grant date. •No Single-Trigger Vesting Acceleration upon a Change in Control; No Liberal Change in Control Definition. Award vesting does not automatically accelerate upon “change in control”. Change in control is only triggered if > 50% of shares and voting rights are transferred. •No Tax Gross Ups. RSU program does not provide tax gross ups (warrants issued to independent directors may include tax gross up for fees paid to purchase warrants).

2 ABILITY TO RAISE CAPITAL OPPORTUNISTICALLY TO SUPPORT STRATEGY • Board delegation helps keep the company on equal footing with US peers and provides flexibility to quickly raise capital to take advantage of potential business and M&A opportunities • Seeking approval to increase share capital through equity/convert: – Capital increase with rights offering, without rights offering, private placement or public offering up to 6M shares, (19.8% of our share capital as of March 31, 2019) – Debt issuance up to €225M nominal value • Cancels and replaces existing delegation from 2018 AGM for equity issuance of 2.9M shares; debt issuance up to €136.3M • Under French law, share capital increase authorizations expire after 26 months.

RENEW AND RETAIN WORLD CLASS DIRECTORS 3 • Renewal of five directors: – Mike Tuchen (renewal) – John Brennan (renewal; independent) – Nora Denzel (renewal; independent) – Steve Singh (renewal; independent) – Thierry Sommelet (renewal; independent) – Mr. Sommelet abstained from certain meetings due to a potential conflict with decisions affecting Bpifrance Investissement, where Mr. Sommelet is a Managing Director. – Resulted in attendance under 75% of meetings, resulting in a no-vote recommendation – We believe that Mr. Sommelet is qualified to serve as a member of our Board of Directors because of his significant financial expertise and international business experience.
