Pyramid Oil Company Reports Fourth Quarter

and Full-Year Financial Results

BAKERSFIELD, Calif. – March 31, 2014 – Pyramid Oil Company (NYSE MKT: PDO) today announced financial results for its fourth quarter and full fiscal year ended December 31, 2013.

Fourth quarter 2013 oil and gas revenue was $1.1 million and $1.1 million in the 2012 fourth quarter. Crude oil production increased to 11,089 barrels of oil equivalent (BOE) from 10,702 BOE in the fourth quarter a year ago. The production increase was offset by a $3.22 decline in realized crude prices, which were $98.40 in the fourth quarter 2013 versus $101.62 in the 2012 fourth quarter. Total revenue for the 2013 fourth quarter was $1.9 million, and included an $809,000 gain on the sale of an oil and gas lease.

Operating income was $515,000 for the fourth quarter of 2013 versus an operating loss of $135,000 in the fourth quarter of 2012. The 2012 fourth quarter results included a $237,000 non-cash valuation allowance associated with a well drilled during the year that did not produce. Fourth quarter 2013 net income was $448,000, or $0.10 per share, versus a net loss of $91,000, or $0.02 per share, during the 2012 fourth quarter.

For the full fiscal year, oil and gas revenue was $4.4 million versus $5.0 million in 2012. Total revenue in 2013 was $5.2 million, and included the previously mentioned gain on a lease sale. The Company reported an operating loss $77,000 for 2013 versus operating income of $1.0 million for 2012. The decline is attributable to a previously announced one-time expense of $1.1 million associated the retirement of the Company’s former president and CEO, who departed effective September 30, 2013.

Full-year net income for 2013, which reflects a $286,000 deferred tax benefit, was $157,000, or $0.03 per share, versus $778,000, or $0.17 per share, in 2012.

At December 31, 2013, Pyramid had cash, cash equivalents, restricted cash and short-term investments of $7.5 million, and total current assets of $9.0 million. The Company also reported long-term assets in the form of certificates of deposit of $1.1 million. Current liabilities at December 31, 2013 were $1.9 million and total liabilities were $3.2 million. Stockholders’ equity at the end of 2013 was $11.0 million.

Michael D. Herman, interim president and CEO, said, “Fiscal 2013 was a pivotal year in which we further strengthened the Company’s financial position, advanced our operational objectives and successfully completed a smooth management transition. We delivered strong bottom-line results in the fourth quarter, and would have been profitable for the full year were it not for the one-time executive retirement-related expense.”

Mr. Herman added, “We also began to explore merger and joint venture opportunities as part of our broader effort to accelerate growth and enhance shareholder value. On February 6, 2014, of this year, we announced we had entered into a definitive merger agreement with privately held Yuma Energy, Inc., a much larger company operating primarily in the U.S. Gulf Coast region. We are working through the process of advancing this transaction, and still intend to complete the merger later this year.”
