01/26/2006

- 2006 earnings per share expected to grow to $2.75 to $2.85, after $0.20 per share estimated cost of SFAS 123R -

LYNDHURST, N.J., Jan. 26 /PRNewswire-FirstCall/ -- Quest Diagnostics Incorporated (NYSE: DGX), the nation's leading provider of diagnostic testing, information and services, announced that for the fourth quarter ended December 31, 2005, net income increased to $130 million, or $0.64 per diluted share, compared to $126 million, or $0.60 per share in 2004. Included in the results were pretax charges of $16 million, or $0.06 per share, related to a product hold at the company's test kit manufacturing subsidiary, NID.

Fourth quarter revenues grew 11.8% over the prior year level to $1.4 billion. The acquisition of LabOne, which was completed on November 1, 2005, increased consolidated revenues by approximately 7%. The performance at NID reduced consolidated revenue growth by approximately 1%. Clinical testing revenues grew 8.7%, with LabOne contributing approximately 3%. Clinical testing volume, measured by the number of requisitions, increased 5.8% and revenue per requisition increased 2.8%.

Fourth quarter operating income was $234 million, or 16.3% of revenues, compared to $221 million, or 17.2% of revenues, in 2004. Operating income as a percentage of revenues compared to the prior year was reduced by approximately 2% due to the performance at NID, and approximately 0.5% due to the inclusion of LabOne.

Bad debt expense improved to 3.9% of revenues, compared to 4.2% a year ago. Days sales outstanding were 46 days. Cash from operations was $303 million, compared to $264 million a year ago. During the quarter the company repurchased 4.0 million common shares for $200 million. Capital expenditures were $46 million.

"Our clinical testing business delivered another quarter of strong performance. During the quarter, we completed the acquisition of LabOne, which further solidifies our industry leadership," said Surya N. Mohapatra, Ph.D., Chairman and Chief Executive Officer. "We are disappointed with the performance at our test kit manufacturing subsidiary, NID, and are actively working to address the issues. As we look to 2006, we expect another strong year of performance at Quest Diagnostics."

Full Year Performance

For the full year 2005, net income increased to $546 million, and earnings per diluted share increased 13% to $2.66. Revenues for the full year increased 7.4% to $5.5 billion. Operating income was $968 million, or 17.6% of revenues, compared to $891 million, or 17.4% of revenues in 2004. Operating income as a percentage of revenues compared to the prior year was reduced by approximately 1% due to the performance at NID. Cash from operations increased to $852 million, compared to $799 million in 2004. During 2005, the company repurchased 7.8 million common shares for $390 million, paid dividends totaling $70 million, and made capital expenditures of $224 million.

Outlook for 2006

The company expects 2006 diluted earnings per common share to be between $2.75 and $2.85 after the estimated $0.20 per share cost of adopting SFAS 123R. Revenues are expected to grow 12.5% to 13.5%, with approximately 8% from LabOne. The company also expects operating income as a percentage of revenues to approximate 17%, reflecting an estimated 1% reduction due to the adoption of SFAS 123R. Cash from operations is expected to approximate $800 million, after the impact of adopting SFAS 123R, and capital expenditures are expected to range from $225 million to $245 million. These estimates are before any potential charges related to integration or restructuring activities.

    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:

       "Accounting for Stock Issued to Employees" ("APB 25"), and related
       interpretations and has chosen to adopt the disclosure-only provisions
       of Statement of Financial Accounting Standards No. 123, "Accounting
       for Stock-Based Compensation" ("SFAS 123"), as amended by Statement of
       Financial Accounting Standards No. 148, "Accounting for Stock-Based
       Compensation - Transition and Disclosure - an amendment of FASB
       Statement No. 123" ("SFAS 148").  The following table presents net
       income and earnings per share, had the Company 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:

       The fair value of each stock option award granted prior to January 1,
    2005 was estimated on the date of grant using the Black-Scholes
    option-pricing model.  The fair value of each stock option award granted
    subsequent to January 1, 2005 was estimated on the date of grant using a
    lattice-based option valuation model.  Management believes a lattice-based
    option valuation model provides a more accurate measure of fair value.
    The expected volatility in connection with the Black-Scholes
    option-pricing model was based on the historical volatility of the
    Company's stock, while 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 weighted
    average assumptions used in valuing options granted in the periods
    presented are noted in the following table:

    4) During the fourth quarter 2005, our test kit manufacturing subsidiary,
       NID, instituted its second voluntary product hold within the last six
       months, due to quality issues. The hold remains in effect while we work
       to address the issues and return product to market.  This latest
       product hold has caused us to reevaluate the financial outlook for NID.
       As a result of this analysis, the Company recorded a pre-tax charge of
       $16 million ($0.06 per diluted share) to write off certain of NID's
       assets.  The charge includes the write-off of $7.5 million of goodwill,
       which is included in other operating expense (income), net, and
       $8.5 million, principally related to products and equipment inventory,
       which is included in cost of services.  This charge, coupled with NID's
       performance reduced pre-tax earnings for the quarter compared to the
       prior year by $29 million or $0.10 per diluted share.  For the full
       year, NID reduced pre-tax earnings compared to the prior year by
       approximately $50 million or $0.16 per diluted share.

       We are currently evaluating our strategic options for NID and expect to
       finalize our plans for NID prior to the end of the second quarter of
       2006.

    5) Other operating expense (income), net represents miscellaneous income
       and expense items related to operating activities, including gains and
       losses associated with the disposal of operating assets.  In addition
       to the amounts related to NID discussed in Note 4 above, for the twelve
       months ended December 31, 2005, other operating expense (income), net
       includes a $6.2 million charge primarily related to forgiving amounts
       owed by patients and physicians, and related property damage as a
       result of hurricanes in the Gulf Coast.  For the twelve months ended
       December 31, 2004, other operating expense (income), net includes a
       $10.3 million charge associated with the acceleration of certain
       pension obligations in connection with the succession of the Company's
       prior CEO.

    6) Interest expense, net for the twelve months ended December 31, 2004,
       includes a $2.9 million charge representing the write-off of deferred
       financing costs associated with the second quarter 2004 refinancing of
       the Company's bank debt and credit facility.

    7) Other (expense) 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 twelve months ended December 31, 2005, other (expense) income, net
       includes a $7.1 million charge associated with the write-down of an
       investment.

    8) For the three months ended December 31, 2005, the Company repurchased
       4.0 million shares of its common stock at an average price of $49.47
       per share for $199.7 million.  For the twelve months ended December 31,
       2005, the Company repurchased 7.8 million shares of its common stock at
       an average price of $49.98 per share for $390.2 million.  For the three
       and twelve months ended December 31, 2005, the Company reissued
       0.7 million and 4.3 million shares for employee benefit plans,
       respectively. For the twelve months ended December 31, 2005, the
       Company has reissued 5.6 million shares in connection with the
       conversion of its contingent convertible debentures.  Since the
       inception of the share repurchase program in May 2003, the Company has
       repurchased 32.4 million shares of its common stock at an average price
       of $42.61 for $1.4 billion.  At December 31, 2005, $122 million of the
       share repurchase authorizations remained available.  In January 2006,
       the Board of Directors expanded the share repurchase authorization by
       an additional $600 million, bringing the total amount authorized and
       available for repurchases to $722 million.

    9) In December 2004, the Company called for redemption all of its
       outstanding contingent convertible debentures due November 2021.  Under
       the terms of the debentures, the holders of the debentures had an
       option to submit their debentures for redemption at par plus accrued
       and unpaid interest or convert their debentures into shares of the
       Company's common stock at a conversion price of $43.75 per share.  The
       outstanding principal of the debentures at December 31, 2004 was
       classified as a current liability within short-term borrowings and
       current portion of long-term debt on the Company's consolidated balance
       sheet. As of January 18, 2005, the redemption was completed and $0.4
       million of principal was redeemed for cash and $249.6 million of
       principal was converted into approximately 5.7 million shares of the
       Company's common stock.

    10) In 2006, the Company expects:
       -- diluted earnings per common share to be between $2.75 and $2.85,
          including the $0.20 per share estimated cost of adopting SFAS 123R,
       -- revenues to grow between 12.5% and 13.5%,
            -- the acquisition of LabOne is expected to contribute 8% revenue
               growth
            -- NID is expected to reduce revenue growth by approximately 0.5%
       -- operating income as a percentage of revenues to approximate 17%,
       -- cash from operations to approximate $800 million,
       -- capital expenditures to range from $225 million to $245 million,
       -- amortization to approximate $10 million,
       -- interest expense to approximate $100 million, and
       -- the estimated impact of SFAS 123R to:
            -- reduce diluted earnings per common share by approximately
               $0.20,
            -- reduce operating income as a percentage of revenues by
               approximately 1%, and
            -- require the tax benefits associated with the exercise of stock
               options be included in cash flows from financing activities.
               In 2005, tax benefits from the exercise of stock options
               increased cash from operations by $33.8 million.

These estimates are before any potential charges related to the integration of LabOne and restructuring activities at NID.
