                            NATIONAL BANKSHARES, INC.
                     ANNOUNCES HIGHER THIRD QUARTER EARNINGS


BLACKSBURG, VA, October 13, 2006: National Bankshares, Inc. (Nasdaq Capital
Market: NKSH) announced today that it had net income for the third quarter of
$3.2 million. This is an increase of 4.8% over the same quarter in 2005, and it
translates to basic net income per share of $0.46. Year-to-date net income at
September 30 totaled $9.43 million, an increase of 2.5% over the same period
last year, and basic net income per share was $1.35. At the end of the third
quarter, the financial holding company headquartered in Blacksburg, Virginia,
had total assets of nearly $845 million.

James G. Rakes, National Bankshares' Chairman, President & CEO, noted that the
company's earnings continue to experience the effects of compression of the net
interest margin. "Interest income earned primarily from loans has lagged behind
the increased interest paid on bank deposits, because loans tend to re-price at
a slower pace than deposits." Mr. Rakes said that he is encouraged by
indications from the Federal Reserve that it is changing its long program of
regular rate increases.

National Bankshares is the parent company of 115 year-old National Bank of
Blacksburg, which does business as National Bank in 26 locations throughout
Southwest Virginia. The company has a non-bank subsidiary, National Bankshares
Financial Services, Inc. that offers investments and insurance. Additional
information about National Bankshares, Inc. is available at
