Tejon Ranch Co. shares gained after the agribusiness and real estate company reported a net loss of $22,000 (0 cents per share) for the third quarter ended Sept. 30, compared to net income of $324,000 (2 cents) for the same period last year. Revenue for the quarter decreased $1.8 million, or -12 percent, compared to the previous year. The company attributed the decline to the “alternate bearing nature of pistachios” and a warm winter, which reduced the pistachio crop by $4.4 million. Other farming operations and water sales also declined, but were partially offset by increases in the company’s real estate side, including land sales and grazing rights, the company said. The company reported results on Thursday. Shares of Tejon Ranch (TRC) closed Friday up $1.14, or 5.8 percent at $20.86 on the New York Stock Exchange.
