SOITEC ANNOUNCES THE Success of its offering of bonds convertible into and/or exchangeable for new or existing ORDINARY shares (OCEANE), due June 2023 for a nominal amount of approximately €150 million

Bernin (Grenoble), France, on June 21, 2018 - Soitec (the "Company"), a world leader in designing and manufacturing innovative semiconductor materials, announces today the successful placement of bonds convertible into and/or exchangeable for new or existing ordinary shares (" OCEANE" ) due June 28, 2023 (the "Bonds"), by way of a private placement to institutional investors, for a nominal amount of €149,999,906.46 (the "Offering").

The net proceeds of the Offering will be used for general corporate purposes. At the time of the issuance, the short-term bank loans of the Company in a principal amount of approximately €30 million will be repaid in full together with interest accrued.

The nominal value per Bond has been set at €104.47, corresponding to a premium of 37.5 % over Soitec reference share price ^[1] on the regulated market of Euronext Paris.

The Bonds will be issued at par on June 28, 2018, the expected settlement and delivery date of the Bonds (the "Issue Date"), and redeemed at par on June 28, 2023. The Bonds will not bear interest (zero-coupon).

Paul Boudre, Soitec's CEO, commented:  "We are very pleased to have seized the opportunity to raise 150 million euros on favourable terms to continue preparing for the future.  The success of this convertible bond issue illustrates the confidence in Soitec shown by investors and strengthens our ability to finance the investments we will need to support the ramp-up of customer demand for our new families of products."

The Bonds may be redeemed prior to maturity at the discretion of the Company, subject to certain conditions. In particular, the Bonds may be redeemed early at Soitec's option as from June 28, 2021 if the arithmetic average of daily product of the volume-weighted average price of Soitec's listed share price on the regulated market of Euronext in Paris and the prevailing conversion/exchange ratio, over a 20-consecutive trading day period among 40 consecutive trading days, exceeds 130% of the nominal value of the Bonds.

Application will be made for the listing of the Bonds on the open market of Euronext in Paris (Euronext Access ^TM ) to occur within 30 days from June 28, 2018.

Conversion Right

Bondholders will be granted a conversion/exchange right of the OCEANEs into new and/or existing ordinary shares which they may exercise at any time from the issue date (i.e. June 28, 2018) and up to and including the 7th business day preceding the maturity date or the relevant early redemption date, as the case may be.

The conversion/exchange ratio of the Bonds is set at one ordinary share per Bond subject to standard adjustments in certain cases. Upon exercise of their conversion/exchange right, bondholders will receive at the option of the Company new and/or existing Company ordinary shares carrying in all cases all rights attached to existing ordinary shares as from the date of delivery.

For information purposes, in the event only Soitec new ordinary shares are delivered upon conversion, such conversion would represent a maximum dilution of 4.58 % of the current share capital of the Company ^[2] .

Lock-up

In the context of the Offering, the Company has agreed to a lock-up undertaking for a period starting from the announcement of the final terms and conditions of the Bonds and ending 90 calendar days after June 28, 2018, subject to certain customary exceptions or waiver from the banks in charge of the placement.

Legal framework of the Offering

The Bonds have been offered in compliance with Article L. 411-2-II of the French monetary and financial code ( Code monétaire et financier ), as per the authorization granted by the Company's extraordinary general meeting held on July 26, 2017 (14 ^th resolution), by way of a private placement to institutional investors in France and outside France (excluding in particular the United States of America, Canada, Australia or Japan).

Any failure to comply with these restrictions may constitute a violation of the securities laws of any such jurisdiction.

No communication or information relating to the offering may be transmitted to the public in a country where there is a registration obligation or where an approval is required. No action has been or will be taken in any country in which such registration or approval would be required. The issuance or the subscription of the Bonds may be subject to legal and regulatory restrictions in certain jurisdictions; none of Soitec and the banks in charge of the placement assumes any liability in connection with the breach by any person of such restrictions.

This press release is an advertisement and not a prospectus within the meaning of Directive 2003/71/EC of the European Parliament and the Council of November 4, 2003 as amended (the "Prospectus Directive").

The Bonds are offered only by way of a private placement in France to persons referred to in Article L.411-2-II of the French monetary and financial code (Code monétaire et financier) and outside France (excluding the United States of America, Australia, Canada and Japan), and there will be no public offering in any country (including France).

Prohibition of sales to European Economic Area retail investors in the European Economic Area

No action has been undertaken or will be undertaken to make available any Bonds to any retail investor in the European Economic Area. For the purposes of this provision, the expression "retail investor" means a person who is one (or more) of the following:

2. a customer within the meaning of Directive 2002/92/EC (as amended, the "Insurance Mediation Directive"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II.

Consequently no key information document required by Regulation (EU) 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the Bonds or otherwise making them available to retail investors in the European Economic Area has been prepared and therefore offering or selling the Bonds or otherwise making them available to any retail investor in the European Economic Area may be unlawful under the PRIIPS Regulation.

For the purposes of this paragraph, the expression "offer to the public of the Bonds" in any Relevant Member State, means any communication, to individuals or legal entities, in any form and by any means, of sufficient information on the terms and conditions of the offering and on the Bonds to be offered, thereby enabling an investor to decide to purchase or subscribe for the Bonds, as the same may be varied in that Relevant Member State.

These selling restrictions with respect to Relevant Member States apply in addition to any other selling restrictions which may be applicable in the Relevant Member States who have implemented the Prospectus Directive.
