Quest Diagnostics Reports Strong Performance in First Quarter 2006

04/20/2006

- Revenues grew 18% and earnings per share grew 13% -

LYNDHURST, N.J., April 20 /PRNewswire-FirstCall/ -- Quest Diagnostics Incorporated (NYSE: DGX), the nation's leading provider of diagnostic testing, information and services, announced that for the first quarter ended March 31, 2006, net income increased to $145 million from $132 million in the first quarter of 2005. Earnings per diluted share increased 13% to $0.72 from $0.64 a year ago. Included in the 2006 results were pretax special charges of $27 million, or $0.08 per share, primarily associated with integration activities; and a pretax gain of $16 million, or $0.05 per share, associated with the sale of an investment. The company's first quarter 2006 results include $19 million of pretax expenses, or $0.06 per share, associated with stock-based compensation recorded in accordance with SFAS 123R.

First quarter revenues grew 17.9% over the prior year level to $1.6 billion. The acquisition of LabOne, which was completed on November 1, 2005, increased consolidated revenues by approximately 10%. The performance at NID, the company's test kit manufacturing subsidiary, reduced consolidated revenue growth by approximately 1%. Clinical testing revenues grew 13.4%, with LabOne contributing approximately 5%. Clinical testing volume, measured by the number of requisitions, increased 8.7% and revenue per requisition increased 4.3%.

For the first quarter, operating income was $245 million, or 15.7% of revenues, compared to $230 million, or 17.4% of revenues, in 2005. Operating income as a percentage of revenues compared to the prior year was reduced by approximately 1.7% due to special charges, 1.2% due to stock-based compensation (SFAS 123R), 0.8% due to the inclusion of LabOne and 0.7% due to the performance at NID.

Bad debt expense improved to 4.1% from 4.5% a year ago. Days sales outstanding were 43 days, compared to 46 days at the end of 2005. Cash flow from operations increased to $241 million from $136 million in 2005. During the quarter the company repurchased $104 million of its common stock and made capital expenditures of $42 million.

"We had an excellent first quarter," said Surya N. Mohapatra, Ph.D., Chairman and Chief Executive Officer. "We are seeing strong top-line growth and margin expansion resulting from increased interest in new and innovative tests, and from our focus on enhancing the overall experience for patients and physicians. We continue to see opportunities to grow our business profitably, and have increased our outlook for 2006."

Discontinuing NID Operations

On April 19, 2006, the company decided to discontinue the operations of NID after evaluating a number of alternatives. This decision is expected to result in a second quarter pretax charge, preliminarily estimated to be up to $45 million.

Outlook for 2006 Raised

For the full year 2006, revenues are now expected to grow approximately 14%. Operating income is expected to approximate 17% of revenues; cash from operations is expected to exceed $800 million; and capital expenditures are expected to be between $225 million and $245 million. The company raised its expectation for full year earnings per diluted share to between $2.85 and $2.95, from $2.75 to $2.85. These estimates exclude the impact of the anticipated second quarter charge related to discontinuing NID's operations.

       Notes to Financial Tables

    1) On June 20, 2005, the Company effected a two-for-one stock split
       through the issuance of a stock dividend of one new share of common
       stock for each share of common stock held by stockholders of record on
       June 6, 2005.  References to the number of common shares and per common
       share amounts in the accompanying consolidated balance sheets and
       consolidated statements of operations, including earnings per common
       share calculations and related disclosures, have been restated to give
       retroactive effect to the stock split for all periods presented.

    2) The computation of basic and diluted earnings per common share (using
       the if-converted method) is as follows:


                                                  Three Months Ended

     stockholders - basic                        $144.6       $131.6

    Weighted average common shares
     outstanding - diluted                        201.0        206.1

    Basic earnings per common share               $0.73        $0.65

    Diluted earnings per common share             $0.72        $0.64


    3) In December 2004, the Financial Accounting Standards Board issued
       Statement of Financial Accounting Standards ("SFAS") No. 123, revised
       2004, "Share-Based Payment" ("SFAS 123R"). SFAS 123R requires that
       companies recognize compensation cost relating to share-based payment
       transactions based on the fair value of the equity or liability
       instruments issued. SFAS 123R is effective for annual periods beginning
       after January 1, 2006. The Company adopted SFAS 123R effective January
       1, 2006 using the modified prospective approach and therefore has not
       restated results for prior periods. Under this approach, awards that
       are granted, modified or settled after January 1, 2006 will be measured
       and accounted for in accordance with SFAS 123R. Unvested awards that
       were granted prior to January 1, 2006 will continue to be accounted for
       in accordance with SFAS No. 123, "Accounting for Stock-Based
       Compensation" ("SFAS 123"), as amended by SFAS No. 148, "Accounting for
       Stock-Based Compensation - Transition and Disclosure - an amendment of
       FASB Statement No. 123" ("SFAS 148"), except that compensation costs
       will be recognized in the Company's results of operations.

       In the first quarter of 2006, the stock-based compensation expense
       recorded in accordance with SFAS 123R totaled $19.4 million ($11.7
       million, net of tax, or $0.06 per share).  In addition, in connection
       with the adoption of SFAS 123R, net cash provided by operating
       activities decreased and net cash provided by financing activities
       increased in the first quarter of 2006 by $12.7 million related to the
       classification of excess tax benefits from stock-based compensation
       arrangements.

        Prior to the adoption of SFAS 123R, the Company accounted for stock-
       based compensation using the intrinsic value method prescribed in
       Accounting Principles Board Opinion No. 25, "Accounting for Stock
       Issued to Employees" ("APB 25"), and related interpretations and chose
       to adopt the disclosure-only provisions of SFAS 123, as amended by SFAS
       148.  Under this approach, the cost of restricted stock awards was
       expensed over their vesting period, while the imputed cost of stock
       option grants and discounts offered under the Company's Employee Stock
       Purchase Plan was disclosed, based on the vesting provisions of the
       individual grants, but not charged to expense.  Stock-based
       compensation expense recorded in accordance with APB 25, relating to
       restricted stock awards, was $0.2 million for the three months ended
       March 31, 2005.  The following pro forma information is presented for
       comparative purposes and illustrates the pro forma effect on net income
       and earnings per share for the period presented, as if the Company had
       elected to recognize compensation cost associated with stock option
       awards and employee stock purchases under the Company's Employee Stock
       Purchase Plan, consistent with the method prescribed by SFAS 123, as
       amended by SFAS 148 (in millions, except per share data):

      The fair value of each stock option award was estimated on the date of
      grant using a lattice-based option valuation model that uses the
      assumptions in the following table. The expected volatility under the
      lattice-based option-valuation model was based on the current and the
      historical implied volatilities from traded options of the Company's
      stock. The risk-free rate is based on the U.S. Treasury yield curve in
      effect at the time of grant. The expected life of the options granted
      was estimated using the historical exercise behavior of employees. The
      dividend yield is based on the approved annual dividend rate in effect
      and current market price of the underlying common stock at the time of
      grant.

       is the average market price of our common stock at the date of grant.

     4) Other operating expense, net represents miscellaneous income and
       expense items related to operating activities including gains and
       losses associated with the disposal of operating assets and provisions
       for restructurings and other special charges.

       During the first quarter of 2006, the Company finalized its plan
       related to the integration of LabOne, Inc. and recorded a charge of
       $20.7 million associated with executing the integration plan.  The
       $20.7 million charge relates to actions that impact Quest Diagnostics'
       employees and operations and is comprised principally of employee
       severance costs.  In addition, the Company accrued $2.6 million of
       integration costs which were included in goodwill.

       In addition, during the first quarter of 2006, the Company recorded a
       $4.1 million charge related to consolidating its operations in
       California into a new facility.  The costs were comprised primarily of
       employee severance costs and the write-off of certain operating
       assets.

    5) Other income, net represents miscellaneous income and expense items
       related to non-operating activities such as gains and losses
       associated with investments and other non-operating assets.  For the
       three months ended March 31, 2006, other income, net includes a $15.8
       million gain on the sale of an investment.

    6) The following table summarizes the approximate impact of various items
       on year-over-year comparisons for certain financial metrics reported

    7) For the three months ended March 31, 2006, the Company repurchased
       approximately 2.0 million shares of its common stock at an average
       price of $52.05 per share for $104 million.  For the three months ended
       March 31, 2006 the Company reissued approximately 1.6 million shares
       for employee benefit plans.  Since the inception of the share
       repurchase program in May 2003, the Company has repurchased
       approximately 34.4 million shares of its common stock at an average
       price of $43.16 for approximately $1.5 billion.  At March 31, 2006,
       $618 million of the share repurchase authorizations remained available.

    8) During the fourth quarter of 2005, the Company's test kit
       manufacturing subsidiary, NID, instituted its second voluntary product
       hold within a six-month period, due to quality issues, which has
       adversely impacted the operating performance of NID.  As a result, the
       Company evaluated a number of strategic options for NID.  On April 19,
       2006, the Company decided to discontinue NID's operations.  This
       decision is expected to result in a pretax charge in the second quarter
       of 2006 preliminarily estimated to be up to $45 million.  The estimated
       charge is expected to principally relate to the write-off of operating
       assets and the accrual of liabilities associated with employee
       severance costs and various lease commitments.  The associated cash
       expenditures are estimated to be up to $35 million.
