<Page>1 [AMERIANA BANCORP LOGO] NEWS RELEASE Contact: Jerome J. Gassen President and Chief Executive Officer (765) 529-2230 AMERIANA BANCORP REPORTS THIRD QUARTER EARNINGS NEW CASTLE, Ind. (October 31, 2007) - Ameriana Bancorp (NASDAQ:ASBI) today announced net income of $1,390,000 or $0.47 per basic and diluted share for the quarter ended September 30, 2007, compared with a net loss of $92,000 or $0.03 per basic and diluted share in the year-earlier period. For the first nine months of 2007, Ameriana reported net income of $1,344,000 or $0.45 per basic and diluted share compared with net income of $131,000 or $0.04 per basic and diluted share in the same period last year. As previously announced, the Company's results for the third quarter and first nine months of 2007 included the recovery of $2,750,000 in a settlement of certain litigation. This recovery, equivalent to $1,815,000 or $0.61 per share on an after-tax basis, was credited against the Company's provision for loan losses for the quarter and more than offset the provision of $823,000 that included amounts related to two commercial credits that recently were either charged off or specifically reserved. Also, year-to-date 2007 results included second quarter income tax expense of $219,000 or $0.07 per share related to the restructuring of the Company's bank-owned life insurance program. Highlights of the third quarter also included continued growth in the Company's loan portfolio, which has increased 14% to $285,624,000 in the past year as a result of the additional focus Ameriana has placed on expanding its commercial lending business. This focus resulted in commercial loan growth of $8,061,000 or 6% for the third quarter and $19,315,000 or 16% for the nine months ended September 30, 2007, with ending commercial loans totaling $141,893,000. Additionally, the Company has improved its net interest margin significantly in 2007 compared with 2006, and in the third quarter of 2007, Ameriana was successful in sustaining this higher margin level. Commenting on the results, Jerome J. Gassen, President and Chief Executive Officer, said, "We are pleased to report continued momentum in our banking operations, highlighted by ongoing growth in net interest income. This, in turn, reflects both the progress we are making with our commercial lending activities as well as the benefit we are seeing from efforts to structure our balance sheet to achieve a higher, more stable net interest margin. During the quarter, we also made headway in resolving several longstanding credit quality issues, including the significant recovery of funds in certain long-running litigation. This settlement not only resulted in a positive adjustment to our provision for loan losses, it also eliminated the distraction this litigation caused and the substantial legal and professional expenses associated with it. "We recognize that recent changes in the real estate and credit markets likely will exert pressures on consumers and asset values in the near term," Gassen added. "However, considering our progress on several fronts, including the inroads we are making to reach new customers and expand our product capabilities, we are cautiously optimistic that Ameriana can sustain its momentum in the current economic climate." -MORE- <Page>2 ASBI Reports Third Quarter Results Page 2 October 31, 2007 Ameriana's net interest income for the quarter increased 13% to $2,428,000 compared with $2,157,000 in the year-earlier period. Net interest income for the first nine months of 2007 increased 9% to $7,226,000 versus $6,605,000 in the comparable period last year. Higher net interest income for the quarter and year-to-date period reflected growth in the Company's loan portfolio and improvement in its net interest margin. Net interest margin for the third quarter was 2.74%, stable with the net interest margin of 2.75% in the second quarter of 2007, but 50 basis points ahead of the 2.24% net interest margin in the year-earlier quarter. For the first nine months of 2007, net interest margin improved 40 basis points to 2.70% versus 2.30% in the same period last year. The Company expects this year-over-year trend to continue in the fourth quarter of 2007 due to the portfolio restructuring that was completed in late 2006, when the proceeds from lower-yielding maturing investments were invested in loan growth, especially higher-yielding commercial loans. With no exposure to sub-prime lending products, management believes the Company's overall credit quality remained relatively stable in the third quarter. Non-performing loans at September 30, 2007, totaled $2.4 million, down 28% from $3.4 million at December 31, 2006, and 48% below $4.7 million at September 30, 2006. These declines primarily reflected the resolution of two large credits, with the remaining value of one equaling $352,000 being charged off and the other being conservatively revalued at $1,650,000 with a write down of $427,000 and being reclassified as Other Real Estate Owned. Other Real Estate Owned totaled $3.0 million at September 30, 2007, compared with $801,000 at June 30, 2007, and $610,000 at December 31, 2006. Ameriana's provision for loan losses reflected a credit of $1,927,000 in the third quarter versus a provision of $75,000 in the year-earlier period, primarily due to a $2,750,000 recovery in a settlement of certain litigation. The provision for loan losses for the first nine months of 2007 reflected a credit of $1,747,000 versus a provision of $225,000 in the year-earlier period, again due to the impact of the recovery made during the third quarter. Other income for the third quarter of 2007 was $990,000, up 26% from $784,000 in the same quarter in 2006, primarily reflecting a $72,000 increase in brokerage and insurance commissions, and a reduction of $120,000 in net losses from other real estate owned. The improvement in brokerage and insurance commissions was mainly due to higher commission income from the investment center that resulted from increased sales. Other income for the first nine months of 2007 increased 9% to $2,968,000 from $2,718,000 in the year-earlier period, resulting mostly from the same factors. Other expense for the third quarter increased 10% to $3,550,000 from $3,224,000 in the same quarter last year, primarily reflecting higher salaries and employee benefits related to normal annual increases and the expansion of the Company's commercial lending operations over the past year. Additionally, other expense for the third quarter included major maintenance to office properties and increased marketing activities. Other expense for the first nine months of 2007 totaled $10,462,000, up 9% from $9,574,000 in the first nine months of 2006, again reflecting higher salaries and employee benefits, as well as $203,000 in legal fees related to collection activities in the RLI Insurance Co. matter. -MORE- <Page>3 ASBI Reports Third Quarter Results Page 3 October 31, 2007 The Company's loans (net) increased 13% to $282.9 million at September 30, 2007, from $249.3 at December 31, 2006, and were up 14% from $247.7 million at September 30, 2006. Total investment securities declined to $78.6 million at September 30, 2007, from $129.8 million at December 31, 2006, and from $171.0 million at September 30, 2006, as cash flows from the investment portfolio were used to fund originations of higher-yielding commercial loans. The year-over-year decline in investment securities also reflected the sale of $34.0 million in available-for-sale government agency securities in the fourth quarter of 2006. Total deposits declined $2.6 million to $319.8 million at September 30, 2007, from $322.4 million at the end of 2006, with higher-costing certificates of deposit accounts declining $5.2 million. The combined total for checking, savings, and money market accounts was up $2.5 million for the period. The Bank's markets remain very competitive for deposit products and the Bank continues to utilize pricing strategies designed to produce an acceptable marginal cost for both existing and new deposits. The Company reduced borrowings $14.4 million to $60.3 million at September 30, 2007, from $74.7 million at December 31, 2006, using cash flows from the investment securities portfolio. With stockholders' equity of $33.5 million at September 30, 2007, Ameriana's capital position continues to exceed all of the regulatory minimum capital levels required to be considered a "well-capitalized" institution.
