Houston, Texas – March 28, 2008 – Houston American Energy, Corp. (Nasdaq: HUSA), today reported its financial results for the year ended December 31, 2007. The company reported a net profit for 2007 of $493,456, or $0.02 per share, on revenues of $4,977,172. Operational highlights for 2007 include: * Net income increased to $493,456 from a loss of $512,096 in 2006; * Oil & Gas revenues increased 55% over 2006 levels; * PV-10 value of oil & gas reserves increased almost 7 fold to over $70.0 million; * Year end cash and marketable securities balances exceeded $10.0 million; and * No debt at year end. Mr. John F. Terwilliger President and Chairman of Houston American Energy stated, “I am pleased to report the results of 2007 for Houston American Energy Corp. Management believes 2007 was a transitional year for the company, laying a foundation for anticipated acceleration in growth. Our drilling activities going forward will be in areas where we own a much larger interest then those exploited in the prior year and, if all things remain equal; this projected drilling has the potential to significantly enhance our growth rate. Our previously announced sale of certain assets, if it closes as proposed, should not materially affect this projected growth and will more than double the Company’s cash reserves. This projected growth is organic and fully funded by the Company’s current cash reserves.”
