Exhibit 99.1 

TALEND S.A.

INTERNATIONAL TAX SUMMARIES RELATING TO FOUNDER SHARE WARRANTS
GRANTED UNDER ONE OF THE TALEND S.A. PLANS

The following is a summary of the material income tax and social insurance consequences regarding the sale of the shares acquired upon the exercise of the founder shares warrants (“BSPCE”) that were granted to you under one of the qualifying Talend S.A. BSPCE Plans (together, the “Plans”), resulting from the “tender offer” made by Tahoe Bidco, B.V. to acquire all outstanding Talend S.A. shares.

As for the BSPCE which are not yet vested, Talend S.A. shall allow an accelerated vesting prior to the tender offer, implying that all BSCPE will be vested on the date of the tender offer.

As part of the tender offer, you will therefore exercise all your BSPCE and tender the underlying shares to Tahoe Bidco, B.V. at the $66.00 per share offer price. Tahoe Bidco, B.V. will put a financing or liquidity mechanism in place to allow you to do a cashless exercise of your BSPCE, provided you agree to tender your shares in the tender offer.

This discussion is based on the law in effect in your country as of June 2021. This discussion is general in nature and does not discuss all of the tax consequences that may be relevant to you in light of your particular circumstances, nor is it intended to be applicable in all respects to all categories of beneficiaries.

Please note that tax laws change frequently and occasionally on a retroactive basis. As a result, the information contained in this discussion may be out of date at the time you exercise your BSPCE / sell the shares acquired upon this exercise.

If you are a citizen or resident of more than one country, or are considered a resident of more than one country for local law purposes, or if you have transferred employment or residency since the BSPCE were granted to you, the information contained in this discussion may not be applicable to you in the same manner.

** You should consult with an appropriate professional advisor

as to how the tax or other laws in your country apply to your specific situation.**

Exercise of BSPCE

You will not be subject to income tax or social security contributions as a result of the exercise of your BSPCE.

Sale of shares acquired upon the exercise of the BSPCE

When you sell the shares acquired upon exercise of the BSPCE, the capital gain realized - amounting to the difference between (i) their strike price and (ii) the net sale proceeds received from Tahoe BidCo - will be subject to personal income tax and social contributions.

The tax and social treatment shall however differ whether you worked for more or less than three years in the Talend group at the time of the sale of the relevant shares.

· If you worked for more than three years in the Talend group: the capital gain realized upon the sale of the relevant shares acquired will be subject to the 30% flat tax (combined income tax rate of 12.8% and social tax rate of 17.2%).

Alternatively, you may choose to be taxed at progressive income tax rates, in which case 6.8% of the 17.2% social tax rates will be tax deductible. However, such election will be applied to all your other investment income and may trigger unintended negative tax consequences.

· If you worked for less than three years in the Talend group: the capital gain realized upon the sale of the relevant shares acquired will be subject to an increased 47.2% flat tax (combined income tax rate of 30% and social tax rate of 17.2%).

In the latter case, and as opposed to the situation where you worked for more than three years in the Talend group, you will not be able to opt to be taxed at progressive income tax rates.

Please note that you may be subject to an additional 3% surtax on very high income for a single person (couple) whose income is comprised between €250,001 (€500,001) and €500,000 (€1,000,000) or 4% tax for a single person (couple) whose income exceeds €500,001 (€1,000,000). If these thresholds are met for income received in the current tax year but were not met for income received in the two prior tax years, you may be eligible for a surtax reduction. 

You are responsible for reporting and paying any income tax / social contributions resulting from the sale of the shares acquired upon the exercise of the BSPCE to the local tax authorities.
