SMA Solar Technology AG—Press Release Managing Board of SMA Solar Technology AG Lowers Sales and Earnings Guidance for 2018 –Outlook for 2019 Unchanged Niestetal, November 30, 2018 – Contrary to expectations, the decline in business recorded since September of this year at SMA Solar Technology AG (SMA/FWB: S92) continued in November. The SMA Managing Board therefore expects sales of only €760 million to €780 million for 2018 (previously €800 million to €850 million). The increasing necessary restructuring measures and additional one-off effects will have a further impact on earnings in 2018. The Managing Board expects negative EBITDA in the medium to upper double-digit million euro range (previously: break-even to slightly negative EBITDA). The SMA Managing Board continues to expect sales growth and positive EBITDA for 2019. “The SMA Managing Board has decided early on to adapt the company’s structures to the changed conditions that are characterized by continued strong price pressure,” explained SMA CEO Dr. Jürgen Reinert. “We expect to close the discussions with the works council on the planned restructuring measures soon. We will then start with the implementation at the beginning of next year. In addition, we have already started to introduce new products and solutions in the international markets and have enhanced our sales initiatives in order to increase sales and achieve positive EBITDA in the following year.” About SMA The SMA Group with sales of around €900 million in 2017 is a global leader for solar inverters, a key component of all PV plants.
