LABORATORY CORPORATION OF AMERICA-REGISTERED TRADEMARK-ANNOUNCES
2003 SECOND QUARTER RESULTS

Reports EPS of $0.60; Operating Cash Flow Increases 32 Percent to
$123 Million; Combined Genomic and Esoteric Testing Revenues
Increase 34 Percent


Burlington, NC, July 22, 2003 - Laboratory Corporation of America-
Registered Trademark-Holdings (LabCorp-Registered Trademark-) (NYSE:
LH) today announced results for the quarter ended June 30, 2003.

Second Quarter Results:
Revenues for the quarter were $743.7 million, an increase of 21.5
percent compared to the same period in 2002. Testing volume,
measured by accessions, increased approximately 16.0 percent and
price per accession increased approximately 5.5 percent compared to
second quarter 2002.

Net income for the quarter increased to $86.4 million, or $0.60 per diluted
share, compared to 2002 second quarter net income of $78.5 million, or $0.55
per diluted share. Earnings before interest, taxes, depreciation and
amortization (EBITDA) were $187.4 million for the quarter, or 25.2 percent
of net sales, compared to $156.4 million, or 25.5 percent of net sales, for
the same period in 2002.

During the quarter, the Company repaid $50 million in borrowings
under its revolving line of credit, and repurchased approximately
$53 million of Company stock. Operating cash flow was $123.2 million
and the cash balance at the end of the quarter was $33.9 million.

"Our financial results, which include solid revenue growth and
EBITDA performance, continued to be strong," said Thomas P. Mac
Mahon, chairman and chief executive officer. "Cash generation was
substantial, debt was further reduced, additional shares of LabCorp
stock were repurchased, and our integration and synergy savings
objectives for Dynacare and DIANON were achieved. Importantly, our
financial performance was enhanced by our successful strategy to
increase our genomic and esoteric testing businesses. We anticipate
that our August launch of EXACT Sciences' colorectal cancer
screening test will further demonstrate the value and significance
of this strategy."

Six-Month Results:
Revenues for the period were approximately $1,455.9 million, an
increase of 21.1 percent compared to the same period in 2002.
Testing volume, measured by accessions, increased approximately 15.0
percent and price per accession increased approximately 6.0 percent,
compared to the comparable period in 2002.

Net income for the period increased to $160.3 million, or $1.10 per
diluted share, compared to 2002 six-month net income of $144.3
million, or $1.01 per diluted share. EBITDA was $353.1 million, or
24.3 percent of net sales, compared to $294.0 million, or 24.4
percent of net sales, for the same period in 2002.

EBITDA represents earnings before net interest expense, income taxes, depreciation and amortization, and includes the Company's proportional share of the underlying EBITDA of the income from equity investments. The Company uses EBITDA extensively as an internal management performance measure and believes it is a useful, and commonly used measure of financial performance in addition to earnings before taxes and other profitability measurements under generally accepted accounting principles ("GAAP"). EBITDA is not a measure of financial performance under GAAP. It should not be considered as an alternative to earnings before income taxes (or any other performance measure under GAAP) as a measure of performance or to cash flows from operating, investing or financing activities as an indicator of cash flows or as a measure of liquidity. The following table reconciles earnings before income taxes, representing the most comparable measure under GAAP, to EBITDA for the three- and six-month periods ended June 30, 2003 and 2002: Three Months Six Months Ended June 30, Ended June 30, ---------------- ------------------ 2003 2002 2003 2002 ----------------- ------------------ Earnings before income taxes $ 146.4 $ 131.3 $ 271.7 $ 243.7 Add: Interest expense 10.0 4.2 21.4 8.4 Investment income (2.4) (1.2) (4.7) (2.0) Other (income) expense, net 0.2 (0.2) 0.3 0.4 Depreciation 22.8 17.1 44.7 33.2 Amortization 9.5 5.2 18.0 10.3 Equity investments' depreciation And amortization 0.9 -- 1.7 -- ------ ------ ------- ------ EBITDA $ 187.4 $ 156.4 $ 353.1 $ 294.0 ====== ====== ====== ======
