Following Sika AG's (the "Issuer" or "Sika") successful offering (the "Offering") and provisional allocations of CHF 1,650 million senior convertible bonds (the "Bonds") due 2025 on May 15, 2018 and the expiration of the advance subscription rights period on May 28, 2018, the final allocations of the bonds have been made today and will be communicated to the institutional investors on May 29, 2018.  

As of May 28, 2018, 12:00 noon CET, 2,917,820 advance subscription rights, corresponding to 15,772 Bonds (19.12% of the total issue size of CHF 1,650 million), were exercised. Accordingly, the provisional allocations to institutional investors who participated in the bookbuilding on May 15, 2018 will be reduced on a pro rata basis ("clawback"). As a result, Bonds in the aggregate amount of approximately CHF 1,335 million have been finally allocated to such institutional investors and Bonds in the aggregate amount of approximately CHF 315 million have been finally allocated to investors who exercised their advance subscription rights.

The Settlement of the Offering (the "Settlement Date") is expected to take place on June 5, 2018. The Bonds are expected to be admitted to trading on the SIX Swiss Exchange as of June 1, 2018.

The Issuer has agreed to a 90-day lock-up period from the Settlement Date.

As expected, the Bonds have been rated by Standard & Poor's in line with the Issuer's corporate rating (A- (stable outlook)).

UBS acted as Sole Global Coordinator and Sole Bookrunner.
