Viskase Companies, Inc. announced earnings results for the first half ended June 30, 2018. For the first half, the company’s net sales increased from $188.8 million to $192.6 million, up 2% from the first half 2017 on a constant currency basis. The increase was driven primarily by higher demand for NOJAX and plastic casings. Operational EBITDA was $28.1 million or 14.6% of net sales on a constant currency basis, which was 30 basis points lower than prior year due to the gross margin drivers previously explained, partially offset by lower operating expenses excluding onetime integration cost. Total net debt decreased from $263.1 million at the end of 2017 to $226.1 million at June 30, 2018.
