Company at a Glance
  A pioneering closed-end investment company investing primarily in equity securities of Master Limited Partnerships (“MLPs”) operating energy infrastructure assets
 
  Objectives: Yield, Growth, Quality
About Master Limited Partnerships
MLPs are limited partnerships whose interests are traded in the form of units on public exchanges such as the New York Stock Exchange, the NASDAQ and the American Stock Exchange. Buying MLP units makes an investor a limited partner in the MLP. There are currently more than 50 MLPs on the market, mostly in industries related to energy, natural resources, and real estate.
Tortoise Energy Infrastructure Corporation’s Investment Objective: Yield, Growth and Quality
Tortoise Energy invests primarily in MLPs in the energy infrastructure sector. Our goal is to provide our stockholders with a high level of total return with an emphasis on current distributions paid to stockholders and dividend growth. Energy infrastructure MLPs are engaged in the transportation, storage and processing of crude oil, natural gas, and refined products from production points to the end users. Our investments are primarily in midstream and pipeline operations, which produce steady cash flows with less exposure to commodity prices than many alternative investments in the broader energy industry. With the growth potential of this sector along with our disciplined investment approach, we endeavor to generate a predictable and increasing dividend stream for our investors.
A Tortoise Energy Investment Versus a Direct Investment in MLPs
The Company provides its stockholders with an efficient alternative to investing directly in MLPs. A direct investment in an MLP offers the opportunity to receive an attractive distribution that is approximately 80% tax deferred with a low correlation to stocks and bonds. However, the tax characteristics of a direct MLP investment are generally undesirable for tax-exempt investors such as retirement plans. Tortoise Energy is structured as a C Corporation— accruing federal and state income taxes, based on taxable earnings and profits. Because of this innovative structure, pioneered by Tortoise Capital Advisors, institutions and retirement accounts are able to join individual stockholders as investors in MLPs.
Additional features of Tortoise Energy include:
  One Form 1099 per stockholder at the end of the year, thus avoiding multiple K-1s and multiple state filings for individual partnership investments;
 
  A professional management team, with nearly 100 years combined investment experience, to select and manage the portfolio on your behalf;
 
  The ability to access investment grade credit markets to enhance the portfolio size and dividend rate, and
 
  Access to direct placements and other investments not available through the public markets.

Dear Fellow Stockholders,
We are pleased to submit to you our report for Tortoise Energy Infrastructure Corporation for the quarter ended May 31, 2005. Since the last report, we raised an additional $90 million of investment funds through the issuance of Tortoise Notes and Money Market Preferred Stock. As of May 31, 2005, total assets of Tortoise Energy were approximately $671 million.
Tortoise Energy paid its second dividend for fiscal year 2005 of $0.445 per share to stockholders on June 1, 2005. This increase was due to the successful investment of the Tortoise Notes offering proceeds, and growth in the distributions we received from MLPs. We continue to expect that a significant portion of dividends paid in 2005 will be treated as return of capital for income tax purposes.

Investment Review
Since inception to May 31, 2005, we have invested $183 million in 12 separate direct placements. Subsequent to quarter end, Tortoise Energy completed two direct purchases from MLP issuers. Tortoise Energy purchased 500,000 common units of K-Sea Transportation Partners L.P. for a purchase price of approximately $ 16 million. K-Sea will use the proceeds to repay indebtedness incurred in connection with the acquisition of vessels from Bay Gulf Trading, and also for fleet expansion projects. K-Sea Transportation is a provider of refined petroleum products marine transportation, distribution and logistics services in the northeastern United States and the Gulf of Mexico.
Tortoise Energy also purchased approximately $5,350,000 of Senior Subordinated Units of Crosstex Energy, L.P. The Senior Subordinated Units were purchased at $33.44 each, and convert to Common Units (on a one-for-one basis) on February 24, 2006. Until their conversion to Common Units, the Senior Subordinated Units will receive no distributions from the Partnership. The proceeds will fund the construction of Crosstex’s North Texas Pipeline. Crosstex is a mid-stream natural gas company headquartered in Dallas, Texas.

MLP Overview and Investment Outlook
We continue to believe that MLPs offer a relatively low risk investment, due to the critical role of energy infrastructure to the U.S. economy. Overall positive performance in the MLP sector for the first half of 2005 was driven by:
    Strong distribution growth fueled by solid earnings despite volatility in energy commodity prices;
 
    Increased flow of funds into the sector, driven by increased demand for safe investments with attractive yields, and
 
    Contributions from accretive acquisitions.
We look for these trends to continue to contribute to growth in distributions for the remainder of the year.
Financing Activity
In late April 2005, Tortoise Energy issued $55 million of Tortoise Notes, rated ‘Aaa’ and ‘AAA’ by Moody’s Investors Services, Inc. and Fitch Ratings, respectively. We entered into an interest rate swap arrangement to hedge our interest payment obligations on these Tortoise Notes through April 2014. We also used favorable market conditions to extend our interest rate swap arrangements with respect to outstanding Series A and Series B Tortoise Notes ($110mm aggregate principal amount) through June 2011.
After quarter ending May 31, 2005, Tortoise Energy successfully completed an offering of Series II Money Market Cumulative Preferred Shares (Series II MMP Shares) raising a total of $35 million before fees and expenses of the transaction. The Series II MMP Shares were rated ‘Aa2’ and ‘AA’ by Moody’s Investors Services, Inc. and Fitch Ratings, respectively. After the closing of this last offering of Preferred Stock, total assets were approximately $745 million.
In Conclusion
With the strength of the energy infrastructure sector and the innovative investment structure pioneered by Tortoise Capital Advisors, we believe Tortoise Energy is well positioned to deliver Yield, Growth and Quality to its stockholders. We will communicate with you regularly through quarterly reports, conference calls and press releases. In addition, we invite you to visit our website at www.tortoiseenergy.com for the latest updates.
Sincerely,
The Managers of
Tortoise Capital Advisors, L.L.C.

Notes to Financial Statements (Unaudited)
May 31, 2005
1. Organization
Tortoise Energy Infrastructure Corporation (the “Company”) was organized as a Maryland corporation on October 29, 2003, and is a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to seek a high level of total return with an emphasis on current dividends paid to stockholders. The Company seeks to provide its stockholders with an efficient vehicle to invest in the energy infrastructure sector. The Company commenced operations on February 27, 2004. The Company’s shares are listed on the New York Stock Exchange under the symbol “TYG”.
2. Significant Accounting Policies
A. Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, recognition of distribution income and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
B. Investment Valuation
The Company primarily owns securities that are listed on a securities exchange. The Company values those securities at their last sale price on that exchange on the valuation date. If the security is listed on more than one exchange, the Company will use the price of the exchange that it generally considers to be the principal exchange on which the security is traded. Securities listed on the NASDAQ Stock Market, Inc. (“NASDAQ”) will be valued at the NASDAQ Official Closing Price, which may not necessarily represent the last sale price. If there has been no sale on such exchange or NASDAQ on such day, the security will be valued at the mean between bid and ask price on such day.
The Company may invest up to 30% of its total assets in restricted securities. Restricted securities may be subject to statutory and contractual restrictions on their public resale, which may make it more difficult to obtain a valuation and may limit the Company’s ability to dispose of them. Investments in private placement securities and other securities for which market quotations are not readily available will be valued in good faith by using fair value procedures approved by the Board of Directors. Such fair value procedures consider factors such as discounts to publicly traded issues, securities with similar yields, quality, type of issue, coupon, duration and rating.
The Company generally values short-term debt securities at prices based on market quotations for such securities, except those securities purchased with 60 days or less to maturity are valued on the basis of amortized cost, which approximates market value. If events occur that will affect the value of the Company’s portfolio securities before the net asset value has been calculated (a “significant event”), the portfolio securities so affected will generally be priced using a fair value procedure.

Notes to Financial Statements (Unaudited)
(Continued)
The Company generally values its interest rate swap contracts by discounting the future cash flows from the stated terms of the interest rate swap agreement by using interest rates currently available in the market, or based on dealer quotations, if available.
C. Security Transactions and Investment Income
Security transactions are accounted for on the date the securities are purchased or sold (trade date). Realized gains and losses are reported on an identified cost basis. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts. Distributions are recorded on the ex-dividend date. Distributions received from the Company’s investments in master limited partnerships (“MLPs”) generally are comprised of ordinary income, capital gains and return of capital from the MLP. The Company records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded, as the actual character of these distributions are not known until after the fiscal year-end of the Company.
For the period from February 27, 2004 (commencement of operations) through November 30, 2004, the Company estimated the allocation of investment income and return of capital for the distributions received from MLPs within the Statement of Operations. Previously, the Company had estimated approximately 18% as investment income and approximately 82% as return of capital.
Subsequent to November 30, 2004, the Company adjusted the amount of investment income and return of capital it recognized based on the 2004 tax reporting information received from the individual MLPs. This reclassification amounted to a decrease in pre-tax net investment income of approximately $2.2 million ($1.3 million net of deferred tax benefit), and corresponding increase in unrealized appreciation of investments for the period from December 1, 2004 through May 31, 2005. The reclassification is reflected in the accompanying financial statements.
D. Dividends to Stockholders
Dividends to common stockholders are recorded on the ex-dividend date. The character of dividends to common stockholders made during the year may differ from their ultimate characterization for federal income tax purposes. For the periods ended May 31, 2005 and November 30, 2004, the Company’s dividend, for book purposes, was comprised entirely of return of capital as a result of the net investment loss incurred by the Company in each reporting period. For the period ended November 30, 2004, for tax purposes, the Company determined the current dividend to common stockholders is also comprised of 100% return of capital.

Notes to Financial Statements (Unaudited)
(Continued)
Dividends to preferred stockholders are based on variable rates set at auctions, normally held every 28 days. Dividends on preferred shares are accrued on a daily basis for the subsequent 28 day period at a rate as determined on the auction date. Dividends on preferred shares are payable every 28 days, on the first day following the end of the dividend period.
E. Federal Income Taxation
The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. The Company invests its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Company reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Company’s tax expense or benefit will be included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.
F. Organization Expenses, Offering and Debt Issuance Costs
The Company is responsible for paying all organization expenses, which are expensed as incurred. Offering costs related to the issuance of common and preferred stock are charged to additional paid-in capital when the shares are issued. Debt issuance costs related to the auction rate senior notes payable are capitalized and amortized over the period the notes are outstanding.
G. Derivative Financial Instruments
The Company uses derivative financial instruments (principally interest rate swap contracts) to manage interest rate risk. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. The Company does not hold or issue derivative financial instruments for speculative purposes. All derivative financial instruments are recorded at fair value with changes in value during the reporting period, and amounts accrued under the agreements, included as unrealized gains or losses in the Statement of Operations. Monthly cash settlements under the terms of the interest rate swap agreements are recorded as realized gains or losses in the Statement of Operations.

H. Indemnifications
Under the Company’s organizational documents, its Officers and Directors are indemnified against certain liabilities arising out of the performance of their duties to the Company. In addition, in the normal course of business, the Company may enter into contracts that provide general indemnification to other parties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred, and may not occur. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
3. Concentration of Risk
The Company’s investment objective is to seek a high level of total return with an emphasis on current dividends paid to its stockholders. Under normal circumstances, the Company intends to invest at least 90% of its total assets in securities of domestic energy infrastructure companies, and will invest at least 70% of its total assets in equity securities of MLPs. The Company may invest up to 25% of its assets in debt securities, which may include below investment grade securities. Companies that primarily invest in a particular sector may experience greater volatility than companies investing in a broad range of industry sectors. The Company may, for defensive purposes, temporarily invest all or a significant portion of its assets in investment grade securities, short-term debt securities and cash or cash equivalents. To the extent the Company uses this strategy, it may not achieve its investment objectives.
4. Agreements
The Company has entered into an Investment Advisory Agreement with Tortoise Capital Advisors, LLC (the “Adviser”). Under the terms of the agreement, the Company will pay the Adviser a fee equal to an annual rate of 0.95% of the Company’s average monthly total assets (including any assets attributable to leverage) minus the sum of accrued liabilities (other than deferred income taxes, debt entered into for purposes of leverage and the aggregate liquidation preference of outstanding preferred shares) (“Managed Assets”), in exchange for the investment advisory services provided. For the period following the commencement of the Company’s operations through February 28, 2006, the Adviser has agreed to waive or reimburse the Company for fees and expenses in an amount equal to 0.23% of the average monthly Managed Assets of the Company. For years ending February 28, 2007, 2008 and 2009, the Adviser has agreed to waive or reimburse the Company for fees and expenses in an amount equal to 0.10% of the average monthly Managed Assets of the Company.

The Company has engaged U.S. Bancorp Fund Services, LLC to serve as the Company’s administrator. The Company will pay the administrator a monthly fee computed at an annual rate of 0.07% of the first $300 million of the Company’s Managed Assets, 0.06% on the next $500 million of Managed Assets and 0.04% on the balance of the Company’s Managed Assets, subject to a minimum annual fee of $45,000.
U.S. Bank N.A. serves as the Company’s custodian. The Company pays the custodian a monthly fee computed at an annual rate of 0.015% on the first $100 million of the Company’s Managed Assets and 0.01% on the balance of the Company’s Managed Assets, subject to a minimum annual fee of $4,800.
5. Income Taxes
Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax purposes. Components of the Company’s deferred tax assets and liabilities as of May 31, 2005 are as follows:
         
Deferred tax assets:
       
Net operating loss carryforwards

    56,973,370  
 
       
Total net deferred tax liability
  $ 50,938,347  
 
       
For the period from December 1, 2004 to May 31, 2005, the components of income tax expense include $18,494,654 and $2,113,675 for deferred federal and state income taxes (net of federal tax benefit), respectively. For the fiscal year ended November 30, 2004, the Company had a net operating loss for federal income tax purposes of approximately $2,786,000. This net operating loss may be carried forward for 20 years, and accordingly would expire after the year ending November 30, 2024.

  $ 148,110,490  
 
       
6. Investment Transactions
For the period ended May 31, 2005, the Company purchased (at cost) and sold securities (at proceeds) in the amount of $107,023,840 and $20,216,285 (excluding short-term debt securities and interest rate swaps), respectively.
7. Auction Rate Senior Notes
The Company has issued $60,000,000, $50,000,000, and $55,000,000 aggregate principal amount of auction rate senior notes Series A, Series B, and Series C, respectively (collectively, the “Notes”). The Notes were issued in denominations of $25,000. The principal amount of the Notes will be due and payable on July 15, 2044 for Series A and Series B, and April 10, 2045 for Series C. Fair value of the notes approximates carrying amount because the interest rate fluctuates with changes in interest rates available in the current market.
Holders of the Notes are entitled to receive cash interest payments at an annual rate that may vary for each rate period. Interest rates for Series A, Series B, and Series C as of May 31, 2005 were 3.40%, 3.44%, and 3.35%, respectively. The weighted average interest rates for Series A, Series B, and Series C for the period from December 1, 2004 through May 31, 2005, were 2.97%, 2.99%, and 3.38%, respectively. These rates include the applicable rate based on the latest results of the auction, plus commissions paid to the auction agent in the amount of 0.25%. For each subsequent rate period, the interest rate will be determined by an auction conducted in accordance with the procedures described in the Notes’ prospectus. Generally, the rate period will be 28 days for Series A and Series B, and 7 days for Series C. The Notes will not be listed on any exchange or automated quotation system.

Notes to Financial Statements (Unaudited)
(Continued)
The Notes are redeemable in certain circumstances at the option of the Company. The Notes are also subject to a mandatory redemption if the Company fails to meet an asset coverage ratio required by law, or fails to cure a deficiency as stated in the Company’s rating agency guidelines in a timely manner.
The Notes are unsecured obligations of the Company and, upon liquidation, dissolution or winding up of the Company, will rank: (1) senior to all the Company’s outstanding preferred shares; (2) senior to all of the Company’s outstanding common shares; (3) on a parity with any unsecured creditors of the Company and any unsecured senior securities representing indebtedness of the Company; and (4) junior to any secured creditors of the Company.
8. Preferred Shares
The Company has 7,500 authorized preferred shares, of which 1,400 shares (MMP Shares) are currently outstanding. The MMP Shares have rights determined by the Board of Directors. The MMP Shares have a liquidation value of $25,000 per share plus any accumulated, but unpaid dividends, whether or not declared.
Holders of the MMP Shares are entitled to receive cash dividend payments at an annual rate that may vary for each rate period. The dividend rate as of May 31, 2005 was 3.45%. The weighted average dividend rate for the period from December 1, 2004 through May 31, 2005, was 3.12%. This rate includes the applicable rate based on the latest results of the auction, plus commissions paid to the auction agent in the amount of 0.25%. Under the Investment Company Act of 1940, the Company may not declare dividends or make other distribution on shares of common stock or purchases of such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding Preferred Shares would be less than 200%.
The MMP Shares are redeemable in certain circumstances at the option of the Company. The MMP Shares are also subject to a mandatory redemption if the Company fails to meet an asset coverage ratio required by law, or fails to cure a deficiency as stated in the Company’s rating agency guidelines in a timely manner.
The holders of MMP Shares have voting rights equal to the holders of common stock (one vote per share) and will vote together with the holders of shares of common stock as a single class except on matters affecting only the holders of preferred stock or the holders of common stock.

9. Interest Rate Swap Contracts
The Company has entered into interest rate swap contracts to protect itself from increasing interest expense on its leverage resulting from increasing short-term interest rates. A decline in interest rates may result in a decline in the value of the swap contracts, which may result in a decline in the net assets of the Company. In addition, if the counterparty to the interest rate swap contracts defaults, the Company would not be able to use the anticipated receipts under the swap contracts to offset the interest payments on the Company’s leverage. At the time the interest rate swap contracts reach their scheduled termination, there is a risk that the Company would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. In addition, if the Company is required to terminate any swap contract early due to the Company failing to maintain a required 300% asset coverage of the liquidation value of the outstanding auction rate senior notes or if the Company loses its credit rating on its auction rate senior notes, then the Company could be required to make a termination payment, in addition to redeeming all or some of the auction rate senior notes. Details of the interest rate swap contracts outstanding as of May 31, 2005, were as follows:
                                         
                    Fixed Rate   Floating Rate   Unrealized
