Exhibit 99.1

            NPTest Reports Results for First Quarter 2004

    SAN JOSE, Calif.--(BUSINESS WIRE)--April 28, 2004--NPTest Holding
Corporation ("NPTest" or the "Company")(Nasdaq:NPTT), a leading
provider of test and diagnostic products and services for the
semiconductor industry, reported financial results for the first
quarter ended March 31, 2004.
    Revenues for the quarter were $58.6 million, up 7% from $55.0
million in the previous quarter. Net loss was $1.2 million, or $0.03
per share on a GAAP basis, versus a net loss attributable to common
shareholders of $68.9 million in the fourth quarter 2003. The net loss
this quarter included special charges of $3.4 million associated with
the acquisition of NPTest, Inc. by NPTest Holding Corporation, the
subsequent initial public offering (IPO) in 2003 and filing of
Registration Statement of Form S-4 in 2004. On a non GAAP basis the
operating income was $1.6 million and net income was $1.3 million for
the quarter, or $0.03 per share.
    Net orders for the quarter were $91.4 million, up more than 75%
from last quarter. This increase was driven both by Service orders,
which are typically strong in the first quarter, and incremental
Sapphire NP(TM) business. The Company finished the quarter with $93
million in cash and no debt.
    "We are very pleased with our financial and operational results
for the first quarter," stated Ashok Belani, president and chief
executive officer, NPTest. "We successfully executed against all our
key strategic objectives -- most important among these was our success
in establishing our new test platform, Sapphire NP, in the market,
with customer acceptance exceeding our expectations. In addition, we
beat our financial objectives, and new higher speed bus technologies
such as PCI Express presented excellent opportunities at the high end
of the ATE performance spectrum for our EXA3000 product line." Belani
concluded, "These factors, coupled with broad based increase in demand
for test capacity, are causing us to feel more optimistic about our
business prospects over the coming quarters."
