BOWIE, Md., Feb. 16, 2011 (GLOBE NEWSWIRE) -- James W. Cornelsen, President and Chief Executive Officer of Old Line Bancshares, Inc. (Nasdaq:OLBK), the parent company of Old Line Bank, reported for the twelve months ended December 31, 2010 that net income available to common stockholders of $1.5 million, after inclusion of $574,369 in merger and integration expenses, remained comparable to the twelve months ended December 31, 2009. Earnings per basic and diluted common share were $0.39 and $0.38, respectively, for the twelve months ended December 31, 2010 and $0.40 for the same period in 2009.

Mr. Cornelsen said "2010 was a year of incredible accomplishments as we announced the pending acquisition/merger of Maryland Bankcorp, Inc. and made significant progress towards enhancing the value of our franchise. I am happy to report that the stockholders of both companies approved the merger in January 2011 and we are currently working to obtain regulatory approval. This acquisition will create the sixth-largest independent commercial bank based in Maryland, with assets of more than $750 million and with 20 full service branches serving five counties.  I am very happy to report that we were able to increase operating earnings even though we expended significant resources and energies towards completing the acquisition/merger. Inclusive of tax adjustments, these expenses negatively impacted net income available to common stockholders approximately $400,000. We also improved operating performance in spite of adding two new branches to our network in July and September of 2009 and the Greenbelt lending team during the last week of December 2009. We believe that our prior investments in talent and infrastructure will allow us to achieve our goal of becoming the premier community bank east of Washington, D.C. and that the experience of our team will allow us to successfully integrate the two banks." 

The continued profitability of the company was primarily the result of a $2.1 million increase in net interest income resulting from a $1.4 million increase in total interest revenue and a $637,091 decrease in total interest expense. The increase in total interest revenue derived primarily from the $30.8 million or 12.21% growth in average net loans. These improvements were offset by a $182,000 increase in the provision for loan losses.

These improvements in interest income were also offset by a $467,765 decrease in non-interest revenue and a $2.1 million increase in non-interest expense.  Non-interest revenue declined during the twelve month period primarily because of an approximately $287,000 decline in rent and other revenue from our investment in Pointer Ridge Office Investment, LLC and a $158,551 decline in gain on sales of investment securities. During 2009, Pointer Ridge produced $567,000 in rental income that is included in other fees and commissions. As we previously reported, approximately $300,000 of that amount derived from a non-recurring lease termination fee. The absence of the lease termination fee in 2010 and the subsequent loss of additional tenants in spaces that Old Line Bank and Pointer Ridge lease to tenants were the major causes of the decline in non-interest revenue. We also did not sell any investments during the twelve months ended December 31, 2010 which contributed to the decline in non-interest revenue. These declines were partially offset by a $192,724 gain on the sale of other real estate owned. As previously mentioned, the two new branches that we opened in 2009 and the addition of the Greenbelt lending team were the primary causes of the increase in non-interest expense as well as costs associated with the transfer of other real estate owned. 

For the three month period ended December 31, 2010, net income inclusive of non-operating items, primarily merger and integration expenses, declined $270,765. Earnings per basic and diluted common share were $0.05 for the three month period ended December 31, 2010 compared to $0.12 for the three month period ended December 31, 2009. During the three month period ended December 31, 2010, net interest income increased $540.020 or 17.61% as a result of a $411,247 increase in total interest revenue and a $128,773 decrease in total interest expense. Total interest revenue increased primarily as a result of an approximately $32.6 million increase in average net loans outstanding. Non-interest revenue increased $172,055 primarily because of a $192,724 gain on sale of other real estate owned. This gain was partially offset by modest declines in the other components of non-interest revenue. Merger expenses of $387,244 were a major contributor to the increase in non-interest expense. Salaries, employee benefits, equipment, data processing and other operating expenses increased primarily because of increased operating expenses from the branches and the new Greenbelt lending team.

Relative to our peers, our asset quality remains strong. We have three non–accrual loans totaling $2.7 million and two properties in other real estate owned in the amount of $1.2 million. During the 4^th quarter of 2010, we added one loan in the amount of $284,011 to non-accrual status and moved one loan in the amount of $553,039 from non-accrual status to other real estate owned. We also sold one property that was previously reported in other real estate owned and recognized a $192,724 gain on the sale. At December 31, 2010, our total non-performing assets as a percentage of total assets were 0.96%. We continue to work diligently towards resolution of all of these loans or properties.

During the three and twelve month periods, we increased our provision for loan losses because we have seen a modest increase in our historical losses over prior periods and some of our borrowers continue to report weaker profitability. Although we continue to believe that the economy has stabilized, we have not seen any significant improvement in the earnings performance of our borrowers. Because we reserved for a significant portion of the charge-offs that occurred in 2010 during 2009, we were well prepared for the charge-offs that we took during 2010. At December 31, 2010, the allowance for loan losses was $2.5 million or 0.82% of gross loans as compared to $2.5 million or 0.93% of gross loans at December 31, 2009. Our non-accrual and past due loans remain statistically low. Based on our history, internal analysis, ratio of non-performing assets, and the satisfactory historical performance of the loan portfolio, we believe the allowance continues to appropriately reflect the inherent risk of loss in our portfolio and the current economic climate.
