Friedberg, 1 November 2018

voxeljet AG (WKN: A1W556 / ISIN: US92912L1070 / Ticker: VJET / New York Stock Exchange) today announced the exercise of the underwriter’s over-allotment option and, as a consequence, increased its capital through the partial use of its authorised capital approved by the ordinary shareholders at a meeting held on 30 May 2018, from EUR 4,692,000 by EUR 144,000 to EUR 4,836,000. The shares issued in connection with the over-allotment option represent the second tranche of the previously announced capital increase; the first tranche closed on 22 October 2018. In conjunction with the over-allotment tranche of the capital increase, the company is issuing 144,000 new registered ordinary shares with attached dividend entitlements for the financial year 2018, offered in the form of 720,000 American Depositary Shares ("ADSs") at a price of USD 2.57 per ADS. This equals EUR 11.17 per ordinary share (based on the exchange rate as of the close of business in New York on the pricing date), since each ADS represents one-fifth of an ordinary share. The ADSs are listed on the New York Stock Exchange.

The gross proceeds from this tranche of the capital increase amount to approximately USD 1.9 million (EUR 1.6 million), bringing the total gross proceeds from the capital increase to approximately USD 14.4 million (EUR 12.5 million). The company will receive the proceeds from the capital increase, less estimated underwriting discounts and commissions and estimated offering expenses. The company intends to use the net proceeds for general corporate purposes.
