Exhibit 99.1

              FNB Corp. Announces First Quarter Earnings
        and Regulatory Approval for Integrity Financial Merger

    ASHEBORO, N.C.--(BUSINESS WIRE)--April 20, 2006--FNB Corp.
(NASDAQ:FNBN), the holding company for First National Bank and Trust
Company and Dover Mortgage Company, today announced its financial
results for the first quarter of 2006. Net income for the first
quarter increased to $2.677 Million, or $.42 per diluted share, from
$2.306 Million, or $.40 per diluted share, in the same period of 2005,
the gains in net income and earnings per share being 16.1% and 5.0%,
respectively.
    At March 31, 2006, total assets were $1,106,268,000, an increase
of 23.5% from March 31, 2005, loans were $820,710,000, an increase of
18.8%, and deposits were $850,561,000, an increase of 24.2%. Return on
average equity on an annualized basis for the first quarter of 2006
was 10.26%, and return on average assets was 0.98%. Return on tangible
equity and assets (calculated by deducting average goodwill and core
deposit premiums from average equity and from average assets) amounted
to 14.91% and 1.01%, respectively.
    The first quarter of 2006 was the first full quarter of earnings
that included the former United Financial, Inc., which was acquired by
FNB Corp. in November of 2005. United's banking subsidiary, Alamance
Bank (including its division, Hillsborough Bank) was merged with and
into First National Bank and Trust Company effective February 1, 2006.
Included in the first quarter financial results are costs of various
integration expenses and data and other systems conversions which were
accomplished in February. Synergies from the acquisition are expected
to begin being realized during the second quarter. In addition, net
income was reduced $112,000 in the first quarter of 2006 by the
accounting change effective January 1, 2006 that requires recognition
of compensation expense for stock options based on their grant-date
fair value.
    "We are again pleased to report increased quarterly earnings
during a time of merger integrations and challenging interest rate
cycles," reported FNB Chairman Michael C. Miller. "We had an increase
in net interest income in the first quarter of 2006, due to shifts in
interest rates and growth in earning assets. We were also able to
scale back our provision for loan losses as a result of improved loan
loss experience."
    Net interest income increased $2,262,000 or 28.9% in the first
quarter of 2006 compared to the same period in 2005, reflecting the
effect of an increase in the net interest margin, stated on a taxable
equivalent basis, from 4.08% in 2005 to 4.26% in 2006 coupled with a
22.6% increase in the level of average earning assets.
    Noninterest income increased $348,000 or 11.0% in the first
quarter of 2006 compared to the same period in 2005. Increased fees
for deposit account services, increased investment management fees and
a slight improvement in income from mortgage loan sales offset a lower
level of sales of non-FDIC insured investments. Noninterest expense
was $2,193,000 or 30.4% higher in the 2006 first quarter, representing
both the increased size of the organization following the United
acquisition and the conversion/integration and other expenses noted
above.
    At March 31, 2006, the allowance for loan losses was $9,960,000
amounting to 1.25% of loans held for investment compared to 1.25% at
December 31, 2005 and 1.14% at March 31, 2005. The provision for loan
losses recorded in the first quarter of 2006 was $77,000 compared to
the $370,000 provision recorded in the same period of 2005. As of
March 31, 2006, nonperforming loans were $10,100,000 in total compared
to $6,046,000 and $5,773,000 as of December 31, 2005 and March 31,
2005, respectively. Nonaccrual loans and accruing loans past due 90
days or more amounted to $8,549,000 and $1,551,000, respectively at
March 31, 2006, $5,398,000 and $648,000 at December 31, 2005, and
$5,336,000 and $437,000 at March 31, 2005. Loans considered impaired
as of March 31, 2006 totaled $206,000 (of which, loans totaling
$118,000 were also on nonaccrual status) compared to $1,084,000 as of
March 31, 2005. There were no loans considered impaired as of December
31, 2005.
    Miller also commented on FNB's pending merger with Integrity
Financial Corporation, based in Hickory, North Carolina. "We're
pleased that shareholders of both organizations approved this
transaction, and that the Federal Reserve has given its regulatory
approval. We're looking forward to completing the merger, on behalf of
our customers, communities, shareholders and employees." In the
merger, FNB Corp. will change its name to FNB United Corp. and the
combined entity will have over 6,000 shareholders, 10.9 Million shares
outstanding and a market capitalization exceeding $200 Million.
