            AMERIGROUP CORPORATION REPORTS $37,278,000 NET INCOME OR
      $0.71 PER DILUTED SHARE INCLUDING FAVORABLE PRIOR PERIOD DEVELOPMENT

             2006 Full-Year EPS Estimate Increased to $1.45 - $1.55

     VIRGINIA BEACH, Va., April 27 /PRNewswire-FirstCall/ -- AMERIGROUP
Corporation (NYSE: AGP) today announced that net income for the first quarter of
2006 increased 82.4 percent to $37,278,000, or $0.71 per diluted share, compared
with net income of $20,443,000, or $0.39 per diluted share, for the first
quarter of 2005. The first quarter of 2006 includes the reversal of a prior
period revenue accrual of $6,316,000 and favorable prior period medical claims
development of $34,467,000. Excluding the impact of these favorable prior period
amounts, first quarter net income would have been approximately $12,881,000, or
$0.24 per diluted share.

     Total revenues for the first quarter of 2006 increased 20.9 percent to
$673,876,000 compared with $557,512,000 for the first quarter of 2005, resulting
from 20.3 percent organic premium revenue growth primarily due to new products
and markets. Revenues were positively affected by the reversal of a $6,316,000
accrual, or $0.07 per diluted share, which was established in the third quarter
of 2005 with respect to potential premium recoupments in two markets.

     Membership increased approximately 5.0 percent, or 52,000 members, to
1,099,000 at quarter end, as compared with 1,047,000 members at March 31, 2005.
Sequentially, membership decreased by 30,000 members, or 2.7 percent, from the
fourth quarter of 2005, due primarily to the continuing state issues with
enrollment in Florida and Texas.

     Highlights for the first quarter include:

     *    Organic premium revenue increased 20.3 percent compared with the prior
          year;
     *    Entered into the Medicare Special Needs Plan, or SNP, in our Houston
          market;
     *    Awarded two urban regions in Ohio;
     *    Health benefits ratio of 84.9 percent before the impact of the
          favorable prior period amounts;
     *    Days in claims payable of 60 or 56 without the prior period claims
          development, both of which were in line with our expected range of 55
          to 65 days;
     *    Unregulated cash and investments of $187,816,000; and
     *    Cash flow from operations of $155,894,000.

     Commenting on the quarter, Jeffrey L. McWaters, Chairman and CEO of
AMERIGROUP Corporation, said, "Our top-to-bottom analysis of 2005 has provided a
better understanding of what happened to medical costs and trend and confirmed
that the integrity of our business strategy remains strong. We have learned a
great deal from this experience and are committed to using that knowledge to
become a stronger company. Looking beyond the quarter, our increased estimates
for 2006 earnings reflect a number of positive developments in our business and
how we are managing our growth."

     Health Benefits

     Health benefits as a percent of premium revenues were 78.9 percent for the
first quarter of 2006 versus 82.0 percent for the first quarter of 2005. Health
benefits reflect favorable prior period development of $34,467,000, or $0.39 per
diluted share. Excluding the impact of the favorable prior period amounts, the
health benefits ratio would have been 84.9 percent compared to a recast first
quarter 2005 of 84.7 percent, which reflects changes in estimates relating to
2005.



     Selling, General and Administrative Expenses

     The selling, general and administrative expense ratio was 11.8 percent of
total revenues for the first quarter of 2006 versus 11.1 percent in the first
quarter of 2005. The increase is primarily due to several components: salary and
benefits including the effect of the adoption of SFAS 123(R); an increase in
premium tax in certain states; legal fees; development costs in Georgia and
elsewhere; as well as actuarial and consulting services associated with key
operational initiatives.

     Balance Sheet and Cash Flow Highlights

     Cash and investments at March 31, 2006, totaled $794,514,000, of which
$187,816,000 was unregulated. Medical claims liabilities totaled $349,587,000,
representing 60 days in claims payable or 56 days without the prior period
claims development versus 62 days in the previous quarter. Cash flow from
operations for the quarter ended March 31, 2006, totaled $155,894,000, compared
to $43,683,000 for the same period in the prior year. The key drivers of the
change between the two periods relate to the impact of the change in net income,
together with the changes in unearned revenue, premium receivables and income
tax payable.

     Outlook

     The Company is revising its 2006 annual estimates for earnings per diluted
share to be $1.45 to $1.55, which reflect the prior period amounts and a
favorable moderation in estimated medical cost trend from approximately 7.0
percent down to approximately 6.0 percent. This compares to previously issued
earnings per diluted share estimates of $0.70 to $0.85.

The revised estimate is based on the following:

     *    Estimates continue to be predicated on the timing of our expansion
          into the State of Georgia and the assumption that Georgia and other
          new products and markets operate at underwritten levels. We expect
          Georgia to be operational in June 2006;
     *    Organic premium revenue growth remains unchanged in the range of 20.0
          to 25.0 percent, which includes weighted-average rate increases of
          approximately 4.5 percent versus the previous estimate of 4.0 percent;
     *    Health benefits of less than 85.0 percent of premium revenues for the
          full year versus the previous estimate of 86.0 percent, excluding the
          impact from the favorable prior period amounts and including the
          impact of new products and markets;
     *    Selling, general and administrative expenses of less than 12.0 percent
          of total revenues versus the previous estimate of 11.0 percent, which
          include expenses to build our infrastructure to complete operational
          improvement efforts and support future growth. Excluding premium
          taxes, selling, general and administrative expenses are estimated to
          be just over 10.0 percent;
     *    Compensation expense due to the adoption of SFAS 123(R) continues to
          be estimated at $0.09 per diluted share for the year, slightly
          weighted towards the first half of the year;
     *    Income tax rate of approximately 40.0 percent; and
     *    Fully diluted shares outstanding of approximately 52,800,000.
