BARNWELL INDUSTRIES, INC. REPORTS RESULTS

FOR THE THIRD QUARTER AND NINE MONTHS ENDED JUNE 30, 2017

HONOLULU, HAWAII, August 9, 2017 -- Barnwell Industries, Inc. (NYSE American: BRN) today reported a net loss of $512,000 ($0.06 per share) and net earnings of $514,000, $0.06 per share, for the three and nine months ended June 30, 2017, respectively, as compared to net earnings of $775,000 ($0.09 per share) and a net loss of $2,242,000 ($0.27 per share) for the three and nine months ended June 30, 2016, respectively.

Mr. Alexander Kinzler, Chief Executive Officer of Barnwell, commented, ""The loss for the quarter ended June 30, 2017 as compared to last year''s net earnings for the three months ended June 30, 2016 was largely due to a $1,775,000 decrease in land investment profits as there were no lot sales this quarter by the Kukio Resort land development partnerships whereas last year one lot was sold for $20,000,000.  This also resulted in a corresponding decrease in equity in earnings from affiliates, which decreased $2,231,000.  This was partially offset in the current quarter by the Company''s $527,000 gain on the sale of its New York office and general and administrative expenses decreases of $365,000 due to decreases in professional fees and compensation costs.  Last year''s third quarter also included $5,700,000 in revenues from the sale of the second of two luxury homes developed by the Company which generated a nominal profit, and a $1,154,000 impairment of our oil and natural gas properties due to low oil prices, whereas there was no such impairment in the current quarter.

""We are pleased to report that all three of the Company''s segments reported operating profits for the nine months ended June 30, 2017.  The improvement in the Company''s results for the nine months ended June 30, 2017 to net earnings of $514,000, as compared to a $2,242,000 net loss in the nine months ended June 30, 2016, was due primarily to our having no impairment of oil and natural gas properties in the current year period, the aforementioned gain on the sale of the New York office, and higher oil and natural gas prices which increased 31% and 81%, respectively, for the nine months ended June 30, 2017 as compared to the nine months ended June 30, 2016.

""Barnwell had cash, cash equivalents and certificates of deposit of just over $18,600,000 and working capital of just over $19,000,000 at June 30, 2017.""
