|We conducted our review in accordance with standards of the Public Company Accounting Oversight Board (United States).  A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters.  It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole.  Accordingly, we do not express such an opinion.

|Based on our review, we are not aware of any material modifications that should be made to the consolidated condensed financial statements referred to above for them to be in conformity with accounting principles generally accepted in the United States of America.

|We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Peter Kiewit Sons, Inc. and subsidiaries as of December 27, 2003, and the related consolidated statements of earnings, changes in redeemable common stock and comprehensive income, and cash flows for the year then ended (not presented herein); and in our report dated March 2, 2004, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated condensed balance sheet as of December 27, 2003, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

|The Company became aware of an accounting error that occurred during the fourth quarter of 2002 on a nonsponsored joint venture.  The error resulted in an overstatement of 2002 net income by $4 million.  The Company corrected the error during the six months ended June 30, 2003.  The Company does not believe that the correction of this error is material to 2002 operations or to 2003 operations.

|In 2003, the Financial Accounting Standards Board FASB issued FASB Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities, (FIN 46-R).  FIN 46-R addresses the consolidation of variable interest entities in which the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties, or the equity investors lack one or more of the essential characteristics of a controlling financial interest.  FIN 46-R requires enterprises to consolidate and disclose existing unconsolidated variable interest entities in which they are the primary beneficiaries if the entities do not effectively disperse risk among the parties involved. FIN 46-R also requires disclosures by an enterprise holding significant interests in variable interest entities in which it is not a primary beneficiary.  FIN 46-R applies to variable interest entities created or in which interest is obtained after December 31, 2003.  The adoption of FIN 46-R has not had a material impact on the Companys financial statements.  The Company will be required to apply FIN 46-R to all other entities subject to this Interpretation by the beginning of the fiscal year ending December 31, 2005.  The Company is currently assessing the impact of FIN 46-R related to such entities.

|Effective December 29, 2002, the Company adopted, as required, the provisions of Statement of Financial Accounting Standards No. 143 (SFAS 143), Accounting for Asset Retirement Obligations.  SFAS 143 establishes new reporting standards of accounting for the Companys reclamation liability associated with its coal mining operation. The new reporting standards require retirement obligations to be measured at fair value and displayed as a liability when incurred. Associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset and subsequently allocated to expense over the assets useful life.  Prior to implementing SFAS 143, reclamation liability was provided without regard to the time value of money.

|Basic earnings per share has been computed using the weighted average number of shares outstanding during each period.  Diluted earnings per share gives effect to convertible debentures considered to be dilutive common stock equivalents.  The potentially dilutive convertible debentures are calculated in accordance with the if converted method.  This method assumes that the after-tax interest expense associated with the debentures is an addition to income and the debentures are converted into equity with the resulting common shares being aggregated with the weighted average shares outstanding.

|The Company entered into a foreign currency forward contract in June 2004 that has not been designated as a hedging instrument under SFAS 133, Accounting for Derivative Instruments and Hedging Activities.  The forward is used to offset the earnings impact of a U.S. dollar denominated liability of a Canadian subsidiary.  The forward is recorded at fair value based upon quoted market prices, and changes in the fair value of the forward are immediately recognized in Other, net in the Consolidated Condensed Statements of Earnings.

The forward matures in June 2005 and will settle based upon the $U.S. 15 million notional amount and the difference between the current exchange rate and the exchange rate in the forward.  At June 30, 2004, the fair value of the forward was a liability of less than $0.5 million.

|Intersegment sales are recorded at cost.  There were no intersegment sales for the three and six months ended June 30, 2003 and June 30, 2004.  Operating income is comprised of net sales less all identifiable operating expenses, allocated general and administrative expenses, gain on sale of operating assets, depreciation and amortization.

|On November 19, 2002, a suit was filed in the District Court, City and County of Broomfield, Colorado for an unspecified amount of damages by Gary Haegle, derivatively on behalf of Level 3 Communications, Inc. (Level 3), against Walter Scott, Jr., James Q. Crowe, R. Douglas Bradbury, Charles C. Miller, III, Kevin V. OHara, Mogens C. Bay, William L. Grewcock, Richard Jaros, Robert E. Julian, David C. McCourt, Kenneth E. Stinson, Michael B. Yanney, Colin V. K. Williams (collectively, the Level 3 Directors) and PKS.  The suit alleges that the Level 3 Directors breached their fiduciary duty with respect to various transactions between Level 3 and PKS, and that PKS aided and abetted the Level 3 Directors in their alleged breach of fiduciary duty.  The suit also alleges that PKS exercised improper control over certain of the Level 3 Directors.  On January 27, 2004, the Court issued an order to stay the proceedings until June 17, 2004 pending the results of the investigation of the allegations set forth in the suit by the Special Litigation Committee of the Level 3 Board of Directors.  On June 26, 2004, the Court issued a subsequent order extending such stay until August 2, 2004.  PKS believes that the factual allegations and legal claims made against it are without merit and intends to vigorously defend them.

|On August 7, 2003, BBC-MEC, a Joint Venture (the Joint Venture), and its two joint venture partners, including Mass. Electric Construction Co., a subsidiary of PKS, received target letters from the U.S. Department of Justice and the United States Attorney for the District of Connecticut (DOJ), notifying the Joint Venture and its joint venture partners that each was a target of a criminal investigation in connection with a certain portion of the work performed by the Joint Venture to electrify a high speed rail line from New Haven, Connecticut, to Boston, Massachusetts. The target letters specified potential violations of various federal statutes based on allegations of misconduct in connection with a portion of the work, and invited the parties to meet with the DOJ and attempt to resolve the matter. The parties did meet on October 23, 2003, and the DOJ was provided with pertinent information that it might not have otherwise previously considered in its investigation. The Joint Venture and its joint venture partners also agreed to cooperate in further testing of certain portions of the work.  The DOJ agreed to enter into a tolling agreement.  By letter dated July 2, 2004, the DOJ notified The Joint Venture and its partners that it had reached a decision not to pursue criminal charges.  The DOJ is also conducting a civil investigation relating to certain proposed change orders and modifications that were issued in conjunction with the work.  The Joint Venture and its joint venture partners believe that the change orders and modifications are appropriate and in accordance with the contracts terms and conditions, and are cooperating in the investigation.  The Company is currently unable to determine the impact of the investigation upon the future financial position, results of operations or cash flows of either the Company or the Joint Venture.

|At the December 10, 2003 meeting of the PKS' Board of Directors, the Board gave preliminary approval to PKS to undertake the formation of an investment entity (the Fund) in which stockholders of PKS would have the opportunity to participate on a pro rata basis to their respective ownership of PKS $0.01 par value common stock (Common Stock).  As currently contemplated, the value of the Fund interests is anticipated to be between 25% and 33% of the aggregate redemption value of the currently issued and outstanding PKS Stock.  However, the actual value of the Fund interests would ultimately be determined by the Board based upon a number of factors, including, the level of liquidity necessary to fund the Companys operations. Consequently, there is no assurance that PKS would actually undertake to form the Fund or distribute the Fund interests to stockholders, or whether the actual value of the Fund interests to be distributed would be more or less than currently anticipated.

|The construction industry is highly competitive and lacks firms with dominant market power.  A contractors competitive position is based primarily on its prices for construction services, its ability to obtain performance bonds, and in certain instances, its reputation for quality, timeliness, experience, and financial strength.  The volume and profitability of the Companys construction work depends to a significant extent upon the general state of the economies of the United States and Canada, and the volume of work available to contractors. Fluctuating demand cycles are typical of the industry, and such cycles determine to a large extent the degree of competition for available projects. The Companys construction operations could be adversely affected by labor stoppages or shortages, adverse weather conditions, shortages of supplies, or governmental action. The volume of available government work is affected by budgetary and political considerations. A significant decrease in the amount of new government contracts, for whatever reason, would have a material adverse effect on the Company.  Public contracts accounted for approximately 71% of the combined prices of contracts awarded to the Company and 73% of revenue earned by the Company for the six months ended June 30, 2004.  Most of these contracts were awarded by government and quasi-government units under fixed price contracts after competitive bidding. Credit risk is minimal with public (government) owners since the Company ascertains that funds have been appropriated by the governmental project owner prior to commencing work on public projects.  Most public contracts are subject to termination at the election of the government. In the event of termination, however, the contractor is entitled to receive the contract price on completed work and payment of termination-related costs.

|The Company performs its construction work under various types of contracts, including fixed unit or lump-sum price, guaranteed maximum price, and cost-reimbursable contracts.  Contracts are either competitively bid and awarded or negotiated.  The Companys public contracts generally provide for the payment of a fixed price for the work performed. Profit on a fixed-price contract is realized on the difference between the contract price and the actual cost of construction, and the contractor bears the risk that it may not be able to perform all the work for the specified amount. Credit risk with private owners is minimized because of statutory mechanics liens, which give the Company high priority in the event of lien foreclosures following financial difficulties of private owners.  Construction contracts generally provide for progress payments as work is completed, with a retainage, ranging from zero to ten percent, to be paid when performance is substantially complete.  In some instances, the Company is able to substitute bank letters of credit or escrowed securities in lieu of retainage.  Construction contracts frequently contain penalties or liquidated damages for late completion and infrequently provide bonuses for early completion.

|The Company frequently enters into joint ventures to efficiently allocate expertise and resources among the venturers and to spread risks associated with particular projects. In most joint ventures, if one venturer is financially unable to bear its share of expenses, the other venturers may be required to pay those costs. The Company prefers to act as the sponsor of its joint ventures. The sponsor generally provides the project manager, the majority of venturer-provided personnel, and accounting and other administrative support services. The joint venture generally reimburses the sponsor for such personnel and services on a negotiated basis. The sponsor is generally allocated a majority of the ventures profits and losses and usually has a controlling vote in joint venture decision-making.  During the six months ended June 30, 2004, the Company derived approximately 84% of its joint venture revenue from sponsored joint ventures and approximately 16% from non-sponsored joint ventures.  The Companys share of joint venture revenue accounted for approximately 27% of its revenue for the six months ended June 30, 2004.

|Due to its competitive nature, the construction industry experiences lower margins than many other industries.  As a result, cost control is a primary focus of the Company.  The ability to control costs enables a contractor to bid work more competitively and also to complete the work profitably.  Further, since the formula price of Common Stock is based upon the Companys book value, formula price is primarily driven by the Companys ability to complete projects profitably.  Consequently, the Company views both margin as a percentage of revenue and general and administrative expenses as a percentage of revenue as key measures of operating results.

|Total revenues decreased $74 million or 8.2% from the same period in 2003.  Certain significant commercial rail, highway and power plant projects were completed during 2003. During the second quarter of 2004, the Company did not experience an offsetting increase in new work for similar projects.  Although the Company added $2.0 billion of backlog during the six months ended June 30, 2004, much of this work is in the early stages and is not yet contributing revenue at the same pace as the projects that completed during 2003.

|Total margin decreased $4 million or 4.3% from the same period in 2003.  Total margin, as a percentage of revenue for the second quarter of 2004 increased to 10.9% compared to 10.4% for the same period in 2003.  The decreased margin is primarily attributable to a $28 million increase in job losses during the second quarter of 2004.  The increase in job losses was attributable to additional costs incurred on certain projects that were accelerated at the owners request.  Agreements related to the change order amounts for the accelerations have not been reached, and, in accordance with the Companys revenue recognition policy, the applicable revenue will not be recognized until cash is received or upon receipt of a signed written agreement.  Also contributing to the decreased margin was a $13 million increase in the allowance for doubtful accounts related to potentially uncollectible receivables pending final resolution of outstanding issues with the owner on two projects.  The decrease was offset by $31 million of margin resulting from the approval of change orders on a bridge project in California.

|General and administrative expenses for second quarter of 2004 decreased $1 million from the same period in 2003.  As a percentage of revenue, general and administrative expenses for the second quarter of 2004 increased to 6.8% compared to 6.3% for the same period in 2003.  The Company experienced an increase in compensation and travel as a result of several operating offices expanding to markets outside of their previous territories and increased estimating efforts.  Offsetting this increase was a decrease in costs related to the proposed corporate conversion to a limited partnership which was abandoned during 2003.

|Total revenues decreased $197 million or 11.5% from the same period in 2003.  Certain significant commercial rail, highway and power plant projects were completed during 2003. For the six months ended June 30, 2004, the Company did not experience an offsetting increase in new work for similar projects.  Although the Company added $2.0 billion of backlog during the six months ended June 30, 2004, much of this work is in the early stages and is not yet contributing revenue at the same pace as the projects that completed during 2003.

|Total margin decreased $1 million or 0.6% from the same period in 2003.  Total margin, as a percentage of revenue for the six months ended June 30, 2004 increased to 10.8% compared to 9.7% for the same period in 2003.  The decreased margin is primarily attributable to a $13 million increase in the allowance for doubtful accounts related to potentially uncollectible receivables pending final resolution of outstanding issues with the owner on two projects.  The decrease was offset by a $7 million reduction in job losses for the six months ended June 30, 2004 as a result of improved cost containment, estimating and bidding efforts and $6 million of additional margin resulting from the approval of change orders on a bridge project in California.

As a percentage of revenue, general and administrative expenses for the six months ended June 30, 2004 increased to 7.7% compared to 6.7% for the same period in 2003.  The Company experienced an increase in compensation and travel as a result of several operating offices expanding to markets outside of their previous territories and increased estimating efforts.  Offsetting this increase was a decrease in profit sharing expense and a reduction in costs related to the proposed corporate conversion to a limited partnership which was abandoned during 2003.

|Cash and cash equivalents increased $23 million to $504 million at June 30, 2004 from $481 million at December 27, 2003.  The increase reflects net cash provided by operations of $90 million, offset by net cash used in investing activities of $30 million and $37 million used in financing activities.

Net cash provided by operating activities for the six months ended June 30, 2004 decreased by $14 million to $90 million as compared to the same period in 2003.  This decrease was primarily due to increased working capital requirements for construction contracts.  Cash provided or used by operating activities is affected to a large degree by the mix, timing, stage of completion and terms of individual contracts which are reflected in changes through current assets and liabilities.

|Net cash used in investing activities for the six months ended June 30, 2004 increased by $6 million to $30 million as compared to the same period in 2003.

|During the six months ended June 30, 2004 and 2003, the Company expended $49 million and $60 million, respectively, on capital expenditures and acquisitions, net of cash.  The Company anticipates that its future cash requirements for capital expenditures and acquisitions will not change significantly from these historical amounts.  Cash generated by joint ventures, while readily available, historically is generally not distributed to partners until the liabilities and commitments of the joint ventures have been substantially satisfied.  Other long-term liquidity uses include the payment of income taxes and the payment of dividends.  Other than the agreements described in the next two paragraphs, as of June 30, 2004, the Company had no material firm binding purchase commitments related to its investments other than meeting the normal course of business needs of its construction joint ventures.  The current portion of long-term debt is $10 million.  PKS paid dividends during the six months ended June 30, 2004 and 2003 of $25 million and $22 million, respectively.  These amounts were determined by the Board of Directors and were paid in January and May of each such year.  The Company also has the commitment to repurchase Common Stock at any time during the year from shareholders.

|The Company has entered into an Asset Purchase Agreement (the Agreement) to acquire a coal mining entity in the Powder River Basin of Wyoming. The total purchase price after post closing adjustments and the assumption of certain liabilities is estimated to be $70 to $80 million. Closing of the Agreement is subject to certain regulatory approvals that have not yet been and may not be received.  If all regulatory approvals are received, the Company hopes to complete the transaction by the end of 2004.

|At the December 10, 2003 meeting of the PKS' Board of Directors, the Board gave preliminary approval to PKS to undertake the formation of an investment entity (the Fund) in which stockholders of PKS would have the opportunity to participate on a pro rata basis to their respective ownership of Common Stock.  As currently contemplated, the value of the Fund interests is anticipated to be between 25% and 33% of the aggregate redemption value of the currently issued and outstanding PKS Stock.  However, the actual value of the Fund interests would ultimately be determined by the Board based upon a number of factors, including, the level of liquidity necessary to fund the requirements noted in the preceding paragraphs. Consequently, there is no assurance that PKS would actually undertake to form the Fund or distribute the Fund interests to stockholders, or whether the actual value of the Fund interests to be distributed would be more or less than currently anticipated.

|The Company entered into a foreign currency forward contract in June 2004 that has not been designated as a hedging instrument under SFAS 133, Accounting for Derivative Instruments and Hedging Activities.  The forward is used to offset the earnings impact of a U.S. dollar denominated liability of a Canadian subsidiary.  The forward is recorded at fair value based upon quoted market prices, and changes in the fair value of the forward are immediately recognized in Other, net in the Consolidated Condensed Statements of Earnings.

|The forward matures in June 2005 and will settle based upon the $U.S. 15 million notional amount and the difference between the current exchange rate and the exchange rate in the forward.  At June 30, 2004, the fair value of the forward was a liability of less than $0.5 million.  A 10% change the Canadian/U.S. exchange rate would result in a gain of approximately $1.5 million in the event of an increase in the exchange rate, or a loss of approximately $1.5 million in the event of a decrease.

|On November 19, 2002, a suit was filed in the District Court, City and County of Broomfield, Colorado for an unspecified amount of damages by Gary Haegle, derivatively on behalf of Level 3 Communications, Inc. (Level 3), against Walter Scott, Jr., James Q. Crowe, R. Douglas Bradbury, Charles C. Miller, III, Kevin V. OHara, Mogens C. Bay, William L. Grewcock, Richard Jaros, Robert E. Julian, David C. McCourt, Kenneth E. Stinson, Michael B. Yanney, Colin V. K. Williams (collectively, the Level 3 Directors) and PKS.  The suit alleges that the Level 3 Directors breached their fiduciary duty with respect to various transactions between Level 3 and PKS, and that PKS aided and abetted the Level 3 Directors in their alleged breach of fiduciary duty.  The suit also alleges that PKS exercised improper control over certain of the Level 3 Directors.  On January 27, 2004, the Court issued an order to stay the proceedings until June 17, 2004 pending the results of the investigation of the allegations set forth in the suit by the Special Litigation Committee of the Level 3 Board of Directors.  On June 26, 2004, the Court issued a subsequent order extending such stay until August 2, 2004.  PKS believes that the factual allegations and legal claims made against it are without merit and intends to vigorously defend them.

|On August 7, 2003, BBC-MEC, a Joint Venture (the Joint Venture), and its two joint venture partners, including Mass. Electric Construction Co., a subsidiary of PKS, received target letters from the U.S. Department of Justice and the United States Attorney for the District of Connecticut (DOJ), notifying the Joint Venture and its joint venture partners that each was a target of a criminal investigation in connection with a certain portion of the work performed by the Joint Venture to electrify a high speed rail line from New Haven, Connecticut, to Boston, Massachusetts. The target letters specified potential violations of various federal statutes based on allegations of misconduct in connection with a portion of the work, and invited the parties to meet with the DOJ and attempt to resolve the matter. The parties did meet on October 23, 2003, and the DOJ was provided with pertinent information that it might not have otherwise previously considered in its investigation. The Joint Venture and its joint venture partners also agreed to cooperate in further testing of certain portions of the work.  The DOJ agreed to enter into a tolling agreement.  By letter dated July 2, 2004, the DOJ notified The Joint Venture and its partners that it had reached a decision not to pursue criminal charges.  The DOJ is also conducting a civil investigation relating to certain proposed change orders and modifications that were issued in conjunction with the work.  The Joint Venture and its joint venture partners believe that the change orders and modifications are appropriate and in accordance with the contracts terms and conditions, and are cooperating in the investigation.  The Company is currently unable to determine the impact of the investigation upon the future financial position, results of operations or cash flows of either the Company or the Joint Venture.
