Title: Vical Reports Second Quarter 2006 Financial Results

Date: 8/1/2006 7:30:00 AM

    SAN DIEGO, Aug. 1 /PRNewswire-FirstCall/ -- Vical Incorporated
(Nasdaq: VICL) today reported financial results for the quarter ended June 30,
2006. Revenues for the second quarter of 2006 were $7.3 million compared with
$4.8 million for the same period of 2005.  The 2006 revenues were driven
primarily by shipments of HIV vaccine to the National Institutes of Health
(NIH) in support of a planned, large Phase 2 trial, while the 2005 revenues
consisted primarily of option exercise fees from Merck & Co., Inc., for three
cancer vaccine targets, and an initial upfront license fee from AnGes MG,
Inc., for DNA delivery of Hepatocyte Growth Factor (HGF) for cardiovascular
applications.

    The net loss for the second quarter of 2006 was $3.2 million or $0.11 per
share, compared with $5.0 million or $0.21 per share for the second quarter of
2005.  Financial results were consistent with the company's projection for an
adjusted net loss for the full year 2006 of between $22 million and $26
million. This projection excludes non-cash, stock-based compensation expense
and, as a result, is not calculated in accordance with U.S. generally accepted
accounting principles (GAAP).  See "Use of Non-GAAP Financial Measure" below.
Vical had cash and investments of $60 million at June 30, 2006.


    Recent Highlights
    * Vical and AnGes MG, Inc. entered into a collaborative agreement for
      Vical's Allovectin-7(R) cancer immunotherapeutic.  Under the agreement,
      AnGes will provide up to $100 million in ongoing clinical trial funding
      and future sales-based milestones as Allovectin-7(R) is successfully
      commercialized.  Vical retains exclusive marketing rights for
      Allovectin-7(R) in the United States and the rest of the world outside
      of specified Asian countries, for which AnGes received exclusive rights.
      Through a scheduled series of cash payments and equity investments
      totaling $22.6 million, including an initial equity investment of $6.9
      million, AnGes will fund the Phase 3 pivotal trial of Allovectin-7(R) to
      be conducted by Vical in the United States in accordance with a Special
      Protocol Assessment (SPA) completed with the U.S. Food and Drug
      Administration (FDA).

    * Vical's lead three-component influenza (flu) DNA vaccine candidate
      provided 100% protection in mice and ferrets against lethal challenges
      with a highly virulent H5N1 avian influenza virus in studies conducted
      by Richard J. Webby, Ph.D., at St. Jude Children's Research Hospital.
      Additionally, in these and earlier studies in mice, simplified versions
      of Vical's vaccine candidate using only two of the three components
      provided high levels of protection against multiple human flu strains
      and against the H5N1 avian flu strain.

    * The National Institute of Allergy and Infectious Diseases (NIAID), part
      of the NIH, after reviewing the mouse and ferret protection data from
      the flu DNA vaccine program, gave Vical accelerated access to
      $2.6 million in funding for further development of the vaccine under a
      grant awarded in September 2005. The funds will be used to complete
      preclinical development of the vaccine and file an Investigational New
      Drug Application (IND) with the FDA, which would allow initiation of a
      Phase 1 safety trial in human volunteers.

    * A West Nile virus (WNV) vaccine candidate administered using Vical's
      proprietary DNA delivery technology was safe and well-tolerated, and
      produced neutralizing antibody WNV-specific responses in all 11 healthy
      volunteers who returned for follow-up testing after completing the
      three-dose vaccination schedule.  The WNV vaccine program is
      fully-funded by the NIH.  The Phase 1, open-label clinical trial study
      was sponsored by NIAID and conducted at the NIH Clinical Center.  The
      data were presented at the American Society of Gene Therapy 2006 Annual
      Meeting in Baltimore, MD.

    Forward-Looking Statements

    This press release contains forward-looking statements subject to risks
and uncertainties that could cause actual results to differ materially from
those projected, including:  whether the company will achieve levels of
revenues and control expenses to meet projected financial performance; whether
Vical or others will continue development of Allovectin-7(R), the influenza
vaccine candidate, the Ebola vaccine candidate, the WNV vaccine candidate, or
any other product candidates being developed by Vical, its collaborators or
licensees; the timing, nature and cost of any additional development; whether
Vical will receive all of the clinical trial funding from AnGes under the
collaborative agreement, which will depend on continued development of
Allovectin-7(R) and certain other conditions; whether Vical will receive any
or all of the sales-based milestone payments and royalties for sales in the
specified Asian countries, which will depend on the efforts of AnGes in
obtaining regulatory approval and commercializing Allovectin-7(R) in those
countries; whether H5N1 or other strains of avian influenza will emerge as
pandemic threats; whether the company will earn all of the remaining
$2.6 million available under the NIAID influenza grant; whether the company
will successfully complete preclinical development of its influenza vaccine
candidate and file an IND; whether the company will secure additional funding
to support Phase 1 human testing of its influenza vaccine candidate; whether
Allovectin-7(R), the influenza vaccine candidate, the Ebola vaccine candidate,
the WNV vaccine candidate, or any other product candidates being developed by
Vical, its collaborators or licensees will be shown to be safe and effective
in clinical trials; and additional risks set forth in the company's filings
with the Securities and Exchange Commission.  These forward-looking statements
represent the company's judgment as of the date of this release.  The company
disclaims, however, any intent or obligation to update these forward-looking
statements.

    Use of Non-GAAP Financial Measure

    This press release contains adjusted net loss projections that are not
calculated in accordance with GAAP. Specifically, the company's adjusted net
loss projection for 2006 excludes an estimated $2 million to $3 million of
non-cash, stock-based compensation expense associated with adoption of
Statement of Financial Accounting Standards No. 123R, "Share-Based Payment,"
on January 1, 2006. As the final amount of such expense cannot yet be
determined, the company currently cannot make a net loss projection in
accordance with GAAP or reconcile its non-GAAP net loss projection to a net
loss projection calculated in accordance with GAAP.

    Vical believes that this non-GAAP financial measure provides meaningful
information regarding the company's performance by excluding expenses that may
not be indicative of the company's core operating results.  In addition, Vical
believes that the use of this non-GAAP financial measure enhances the
consistency and comparability of the company's reported financial results and
enables investors to better evaluate the company's current performance
compared to its past performance.  However, this information should not be
considered in isolation or as an alternative to financial information
calculated in accordance with GAAP.
