NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

October 28, 2005

Note 1 — Basis of Presentation:

The accompanying unaudited consolidated financial statements of Cyberonics, Inc. (Cyberonics) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) for interim financial information, and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the thirteen weeks and the twenty-six weeks ended October 28, 2005 are not necessarily indicative of the results that may be expected for any other interim period or the full year ending April 28, 2006. The financial information presented herein should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the period ended April 29, 2005.

Note 2 — Stock Incentive and Purchase Plan:

As of October 28, 2005, Cyberonics has reserved an aggregate of 14,850,000 shares of Common Stock, for issuance pursuant to its 1996 Stock Option Plan, 1997 Stock Option Plan, 1998 Stock Option Plan, The New Employee Equity Inducement Plan and the 2005 Stock Option Plan (collectively, the Stock Option Plans). Options granted under the Stock Option Plans generally vest ratably over four or five years following their date of grant. The vesting of certain options occurs up to seven years from the grant date. Options granted under the Stock Option Plans have maximum terms of 10 years. The 1997 Stock Option Plan and the 2005 Stock Option Plan allow issuance of either nonstatutory or incentive stock options, while the 1996 and the 1998 Stock Option Plans provide for issuance of nonstatutory stock options exclusively. The 1997 and 2005 Stock Option Plans allow also for the issuance of restricted stock. For the twenty-six weeks ended October 28, 2005, Cyberonics has granted approximately 1,012,600 options issued at fair market value at a weighted average exercise price of approximately $29.71 per share. All grants were made at market prices as of the date of the grant. Stock options to purchase approximately 7.5 million shares at a weighted average exercise price of $19.58 per share were outstanding as of October 28, 2005.

In addition, pursuant to the employment agreement with the Chief Executive Officer, Cyberonics has agreed to issue an additional 150,000 shares of restricted stock, with 75,000 shares each to be granted on the first and second anniversary of the employment agreement, or August 5, 2006 and August 5, 2007, respectively.

The following table illustrates the effect on net income and earnings per share if Cyberonics had applied the fair value recognition provision of Statement of Financial Accounting Standards Board (SFAS) No. 123, “Accounting for Stock-Based Compensation” and SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure” to stock-based employee compensation.

Note 7 — Long -Term Debt:

On September 27, 2005, we issued $125,000,000 of senior subordinated convertible notes due on September 27, 2012 (Notes). Interest on the notes at the rate of 3% per year on the principal amount is payable annually in arrears in cash on March 27 and September 27 of each year, beginning March 27, 2006. The notes are unsecured and subordinated to all of our existing and future senior debt and equal in right of payment with our existing and future senior subordinated debt. Holders may convert their notes which were issued in the form of $1,000.00 bonds into 24.0964 shares of our common stock per bond, which equal to a conversion price of approximately $41.50 per share, subject to adjustments, at any time prior to maturity. Holders who convert their notes in connection with certain fundamental changes may be entitled to a make-whole premium in the form of an increase in the conversion rate. The make-whole premium, depending on the price of the stock and the date of the fundamental change, may range from 6.0241 to 0.1881 shares per bond, when the stock price ranges from $33.20 to $150.00, respectively. If a fundamental change of our company occurs, the holder may require us to purchase all or a part of their notes at a price equal to 100% of the principal amount of the notes to be purchased plus accrued and unpaid interests if any. We may, at our option, instead of paying the fundamental change purchase price in cash, pay it in our common stock valued at a 5% discount from the market price of our common stock for the 20 trading days immediately preceding and including the third day prior to the date we are required to purchase the notes, or in any combination of cash and shares of our common stock. A fundamental change will be deemed to have occurred upon a change of control or a termination of trading. This offering provided net proceeds of approximately $121 million. We used the proceeds for (1) a simultaneous share buyback of 301,000 shares at $33.20 for a total of $9,993,200; (2) the net cost of $13,000,000 of separate convertible bond hedge and common stock warrant transactions, which transactions were designed to limit our exposure to potential dilution from conversion of the notes. These transactions resulted in net cash proceeds of $98,257,000.

Note 8 — Convertible Note Hedge and Warrants:

In September 2005, Cyberonics issued $125,000,000 of senior subordinated convertible notes due 2012, purchased a hedge on the convertible notes (the Bond Hedge) for $38.2 million which matures in September 2012 and sold common stock Warrants (the Warrants) for $25.2 million which matures in September 2012. The notes are convertible into approximately 3.0 million shares of Cyberonics’ common stock. Cyberonics purchased the Bond Hedge, to buy approximately 3.0 million shares of Cyberonics’ common stock at an exercise price of $41.50 per share. Cyberonics issued the Warrants to sell approximately 3.0 million shares of Cyberonics’ common stock at an exercise price of $50.00 per share. The purpose of the purchase of the Bond Hedge and the sale of the Warrants was to limit our exposure to potential dilution from conversion of the notes subject to the bond offering. The bond hedge and the warrants are recorded in stockholder’s equity on the consolidated balance sheet.

Note 9 — Stockholders’ Equity:

Deferred Compensation. In June 2000, the Board of Directors granted 450,000 options at $18.00 per share to purchase shares of Common Stock under a proposed modification to the 1997 Stock Option Plan that was subject to shareholder approval. On December 29, 2000, the shareholders approved the modification to the plan and Cyberonics recorded approximately $2.4 million in deferred compensation expense relating to these options. The charge reflects the difference between the exercise price and the fair market value of the stock on the date shareholder approval was received. The deferred compensation is being amortized to expense over the five-year vesting period of the options. The amortization of this deferred compensation expense was completed during the first quarter of fiscal year 2006. Therefore, no compensation expense was recognized for the thirteen weeks ended October 28, 2005. During the thirteen weeks ended October 29, 2004, compensation expense of $118,000 was recognized. During the twenty-six weeks ended October 28, 2005 and October 29, 2004, compensation expenses of approximately $79,000 and $236,000 have been recognized for the vested portion of this option grant, respectively.

In fiscal 2004, the Board of Directors granted 17,000 shares of restricted stock at market rates that vest over one year and recorded approximately $451,000 in deferred compensation. In fiscal 2006 through October 28, 2005, the Board of Directors granted approximately 230,000 shares of restricted stock at market rates that vest over one or five years and recorded approximately $8,300,000 in deferred compensation. For the thirteen weeks ended October 28, 2005 and October 29, 2004, compensation expenses of approximately $614,000 and $104,000 of compensation expense have been recognized for the vested portion of the restricted stock, respectively. For the twenty-six weeks ended October 28, 2005 and October 29, 2004, compensation expenses of approximately $753,000 and $239,000 of compensation expense have been recognized for the vested portion of the restricted stock, respectively.

Note 10 — Comprehensive Income (Loss):

Cyberonics follows SFAS No. 130, “Reporting Comprehensive Income,” in accounting for comprehensive income (loss) and its components. The comprehensive loss for the thirteen weeks ended October 28, 2005 and October 29, 2004 was ($22,069,454) and ($1,935,998), respectively. The comprehensive loss for the twenty-six weeks ended October 28, 2005 and October 29, 2004 was ($41,025,457) and ($4,830,691).

Note 11 — Income Taxes:

We account for income taxes under the asset and liability method. Under this method, deferred income taxes reflect the impact of temporary differences between financial accounting and tax basis of assets and liabilities. Such differences relate primarily to the deductibility of certain accruals and reserves and the effect of tax loss and tax credit carryforwards not yet utilized. Deferred tax assets are evaluated for realization based on a more-likely-than-not criterion in determining if a valuation allowance should be provided.

We estimate that our effective rate for the twenty-six weeks ended October 28, 2005 to be less than 1%, due primarily to the change in the balance of our valuation allowance combined with state tax and tax on foreign operations. The effective tax rate represents our estimate of the rate expected to be applicable for the full fiscal year. In August 2004, we experienced an ownership change as defined in Section 382 of the Internal Revenue Code (IRC). Our ability to utilize certain net operating losses to offset future taxable income in any particular year may be limited pursuant to IRC Section 382. Due to our operating loss history and possible limitations pursuant to IRC Section 382, we have established a valuation allowance that fully offsets our net deferred tax assets, including those related to tax loss carryforwards, resulting in no regular U.S. federal income tax expense or benefit for financial reporting purposes.

Note 12 — Earnings Per Share:

SFAS No. 128, “Earnings Per Share,” requires dual presentation of earnings per share (EPS): basic EPS and diluted EPS. Basic EPS is computed by dividing net earnings or loss applicable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS includes dilutive stock options and unvested restricted stock that are considered common stock equivalents using the treasury stock method.

The following table sets forth the computation of basic and diluted net earnings per share of common stock:

Excluded from the computation of diluted EPS for the thirteen and twenty-six weeks ended October 28, 2005 were outstanding options and unvested restricted stock to purchase approximately 7.7 million common shares because to include them would have been anti-dilutive. Excluded from the computation of diluted EPS for the thirteen and twenty-six weeks ended October 29, 2004 were outstanding options and unvested restricted shares to purchase approximately 7.5 million common shares, because to include them would have been anti-dilutive.

Cyberonics issued $125 million of senior subordinated convertible notes due in 2012 during the quarter ended October 28, 2005 and, in conjunction with the notes, purchased a Bond Hedge and sold common stock Warrants. The notes are convertible into approximately 3.0 million shares of Cyberonics’ common stock. The dilution is measured in accordance with the “if converted” method of SFAS No. 128, “Earnings Per Share” which assumes conversion of the notes and adjusts net income for interest expense net of tax; however, due to net operating losses the convertible notes are anti-dilutive and are not included in the computation of diluted EPS. Cyberonics purchased call options (the Bond Hedge) to buy approximately 3.0 million shares of Cyberonics’ common stock at an exercise price of $41.50 per share. Purchased call options are anti-dilutive and are not included in the computation of diluted EPS. Cyberonics issued call options (the Warrants) to sell approximately 3.0 million shares of Cyberonics’ common stock at an exercise price of $50.00 per share. In accordance with the treasury stock method of SFAS No. 128, “Earnings Per Share,” the Warrants are not included in the computation of diluted EPS because the Warrants’ exercise price was greater than the average market price of the common stock.

Note 13 — Commitments and Contingencies:

From time to time, Cyberonics may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accounts for contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated.

July 28, 2005, the Court consolidated the two cases under Civil Action No. H-05-2121, styled In re Cyberonics, Inc. Securities Litigation, and entered a scheduling order. On September 28, 2005, the court appointed lead plaintiffs and lead counsel.

The lead plaintiffs filed a consolidated amended complaint on November 30, 2005. The complaint generally alleges, among other things, that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 by making false and misleading statements regarding the efficacy, safety, and marketability of Cyberonics’ Vagus Nerve Stimulation Therapy System device (the “VNS Device”) as a therapy for treatment resistant depression. Lead plaintiffs allege that the defendants failed to disclose that the U.S. Food and Drug Administration (“FDA”) had safety and efficacy concerns about the use of the VNS Device for the treatment of depression, and that certain manufacturing and quality practices, as detailed in FDA’s December 22, 2004 warning letter, existed that negatively impacted Cyberonics’ prospects for obtaining FDA approval to use the VNS Device to treat depression. Lead plaintiffs seek to represent a class of all persons and entities, except those named as defendants, who purchased or otherwise acquired Company securities during the period June 15, 2004 through October 1, 2004. The complaint seeks unspecified monetary damages and equitable or injunctive relief, if available.

Under the current scheduling order, defendants have 60 days to answer or respond to the amended complaint. If defendants move to dismiss the amended complaint, lead plaintiff will have 60 days to respond and defendants will have 45 days to file a reply. We intend to vigorously defend against this lawsuit, however, an adverse result in these lawsuits, or related lawsuits, could have a material adverse effect on us, our financial consolidated condition, results of operations and cash flows.

Note 14 — Use of Accounting Estimates:

The preparation of the Consolidated Financial Statements, in conformity with accounting principles generally accepted in the U.S., requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Our estimates and assumptions are updated as appropriate, which in most cases is at least quarterly. We base our estimates on historical experience or various assumptions that are believed to be reasonable under the circumstances, and the results form the basis for making judgments about the reported values of assets, liabilities, revenues and expenses. Actual results may materially differ from these estimates.

Note 15 — New Accounting Pronouncements:

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs — an Amendment to ARB No. 43, Chapter 4.” This statement amends the guidance in Accounting Research Bulletin (ARB) No. 43, Chapter 4, “Inventory Pricing,” to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Paragraph 5 of ARB 43, Chapter 4, previously stated that “. . . under some circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so abnormal as to require treatment as current period charges. . . .” This statement requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal.” In addition, this statement requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. The provisions of this statement shall be effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The adoption of SFAS No. 151 will not have a material impact on Cyberonics’ consolidated operating results or financial condition.

In December 2004, the FASB issued SFAS No. 153, “Exchange of Nonmonetary Assets,” an amendment to Opinion APB No. 29. The guidance in Accounting Principals Board (APB) Opinion No. 29, “Accounting for Nonmonetary Transactions,” is based on the principle that exchanges of nonmonetary assets should be measured based on the fair value of the assets exchanged. The guidance in that Opinion, however, included certain exceptions to that principle. This statement amends Opinion 29 to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. A nonmonetary exchange has commercial substance if the future

cash flows of the entity are expected to change significantly as a result of the exchange. The provisions of this statement are effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. The adoption of SFAS No. 153 will not have a material impact on Cyberonics’ consolidated operating results or financial condition.

In December 2004, the FASB issued SFAS No. 123 (revised 2004), “Share-Based Payment.” This statement is a revision of FASB Statement No. 123, “Accounting for Stock-Based Compensation.” This statement supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related implementation guidance. This statement establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. This statement focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. This statement does not change the accounting guidance for share-based payment transactions with parties other than employees provided in Statement No. 123 as originally issued and Emerging Issues Task Force (EITF) Issue No. 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services.” This statement does not address the accounting for employee share ownership plans, which are subject to American Institute of Certified Public Accountants (AICPA) Statement of Position 93-6, “Employers’ Accounting for Employee Stock Ownership Plans.” We are required to comply with this statement at the beginning of our fiscal year 2007, or April 29, 2006. This statement applies to all awards granted after the required effective date of April 29, 2006, and to awards modified, repurchased or cancelled after that date. The cumulative effect of initially applying this statement, if any, is recognized as of the required effective date. Cyberonics is currently evaluating the effect that the adoption of SFAS No. 123 (revised 2004) will have on Cyberonics’ consolidated operating results or financial condition.

In March 2005, FASB issued Interpretation (FIN) No. 47, “Accounting for Conditional Asset Retirement Obligations — an interpretation of FASB Statement No. 143.” This interpretation clarifies that the term conditional asset retirement obligation as used in FASB Statement No. 143, “Accounting for Asset Retirement Obligations,” refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. Thus, the timing and (or) method of settlement may be conditional on a future event. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. The fair value of a liability for the conditional asset retirement obligation should be recognized when incurred — generally upon acquisition, construction, or development and (or) through the normal operation of the asset. Uncertainty about the timing and (or) method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists. This Interpretation is effective no later than the end of fiscal years ending after December 15, 2005. The adoption of FIN No. 47 will not have a material impact on Cyberonics’ consolidated operating results or financial condition.

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections — a replacement of Accounting Principles Board (APB) Opinion No. 20 and FASB Statement No. 3.” This statement replaces APB Opinion No. 20, “Accounting Changes,” and FASB Statement No. 3, “Reporting Accounting Changes in Interim Financial Statements,” and changes the requirements for the accounting for and reporting of a change in accounting principle. This statement applies to all voluntary changes in accounting principle. It also applies to changes required by an accounting pronouncement in the unusual instance that the pronouncement does not include specific transition provisions. When a pronouncement includes specific transition provisions, those provisions should be followed. This statement requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle, such as a change in nondiscretionary profit-sharing payments resulting from an accounting change, should be recognized in the period of the accounting change. This statement is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005.

ITEM 2.		MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements can be identified by the use of forward-looking terminology, including “may,” “believe,” “will,” “expect,” “anticipate,” “estimate,” “plan,” “intend” and “forecast” or other similar words. Actual results could differ materially from those projected in the forward-looking statements as a result of a number of important factors.

For a discussion of important factors that could affect our results, please refer to the financial statement line item discussions set forth in this section and to the section entitled “Factors Affecting Future Operating Results,” included herein. Readers are also encouraged to refer to our Annual Report on Form 10-K for the period ended April 29, 2005 for a further discussion of our business and its risks and opportunities.

Overview

We are a neuromodulation company founded to design, develop and bring to market medical devices that provide a unique therapy, Vagus Nerve Stimulation (VNS), for the treatment of epilepsy, treatment-resistant depression and other debilitating neurological, psychiatric diseases and other disorders. VNS Therapy is approved in the U.S. for use as an adjunctive therapy in patients over 12 years of age in reducing the frequency of seizures in patients with partial onset seizures that are refractory or resistant to antiepileptic drugs and without age restrictions or seizure-type limitations in Canada, Europe, Australia and certain countries of eastern Asia. VNS Therapy is also approved in the U.S. as a long-term adjunctive treatment for patients 18 years of age or older with chronic or recurrent treatment-resistant depression (TRD) in a major depressive episode that has not responded to at least four adequate antidepressant treatments and in the European union countries and Canada without age restrictions for the treatment of chronic or recurrent depression in patients who are in a treatment-resistant or in a treatment-intolerant depressive episode.

On July 15, 2005 the Food and Drug Administration (FDA) approved VNS Therapy as a long-term adjunctive treatment for patients 18 years of age or older with chronic or recurrent treatment-resistant depression in a major depressive episode that has not responded to at least four adequate antidepressant treatments. Since February 2005, we have been preparing our organization for approval and launch in depression and we have recently expanded our organization from approximately 500 to 750 personnel, primarily in the areas of sales, case management, clinical engineering, surgical support staff and manufacturing personnel, to create the organizational capacity necessary to support anticipated market demand for VNS Therapy in the epilepsy and depression markets. While we anticipate increases in revenues in fiscal 2006 related to sales of VNS Therapy in the U.S. for TRD, and we believe that we have created adequate organizational capacity to support our expanded business requirements, the scale-up of our organization is substantial. We expect quarterly operating expenses to increase in advance of anticipated increases in quarterly revenues. Furthermore, our expectations for market acceptance in a completely new device market for TRD will likely change as we complete our product launch in TRD and promote awareness and acceptance of VNS Therapy among new psychiatric prescribers. Accordingly, while we expect to achieve revenue growth as a result of this approval, we can provide no assurance as to the size or timing of such growth.

TRD sales and future sales growth depend significantly on whether third-party payers, including private healthcare insurers, managed care plans, Medicare and Medicaid programs and others, agree both to cover the VNS Therapy System and associated procedures and services and to reimburse at adequate levels for the costs of

the VNS Therapy System and the related services in the U.S. or internationally. While we currently have reimbursement approval for epilepsy, we have not yet received broad approval for the treatment of depression. Anticipated growth is highly dependent upon progress in obtaining TRD case-by-case approvals and favorable national and regional coverage policies.

Since inception, we have incurred substantial expenses, primarily for research and development activities that include product and process development and clinical trials and related regulatory activities, sales and marketing activities, manufacturing start-up costs and systems infrastructure. We have also made significant investments in recent periods in connection with sales and marketing activities in the U.S. and clinical research costs associated with new indications development, most notably depression. For the period from inception through October 28, 2005, we incurred a cumulative net deficit of approximately $171 million. We anticipate significant investments in sales and marketing expenses associated with a planned product launch and start-up in depression as well as increasing investments in post-approval clinical studies in epilepsy and depression. Other new indications may be clinically studied. Excluding epilepsy and depression studies, clinical studies are for investigational therapies subject to FDA approval.

Critical Accounting Policies

We have adopted various accounting policies to prepare the Consolidated Financial Statements in accordance with accounting principles generally accepted in the U.S. Our most significant accounting policies are disclosed in Note 1 to the Consolidated Financial Statements in our Annual Report on Form 10-K for the period ended April 29, 2005.

We consider the following accounting policies as the most critical because, in management’s view, they are the most important to the portrayal of our consolidated financial condition and results and the most demanding in terms of requiring estimates and other exercises of judgment.

Accounts Receivable. We provide an allowance for doubtful accounts based upon specific customer risks and a general provision based upon historical trends. An increase in losses beyond that expected by management or that historically have been experienced by us would reduce earnings when they became known.

Inventories. We state our inventories at the lower of cost, first-in, first-out (FIFO) method, or market. Cost includes the acquisition cost of raw materials and components, direct labor and overhead. Management considers potential obsolescence at each balance sheet date. An acceleration of obsolescence could occur if consumer demand should differ from expectations.

Property and Equipment. Property and equipment are carried at cost, less accumulated depreciation. Maintenance, repairs and minor replacements are charged to expense as incurred; significant renewals, improvements and expansions are capitalized. For financial reporting purposes, we compute depreciation using the straight-line method over useful lives ranging from two to nine years. An unanticipated change in the utilization or expected useful life of property and equipment could result in acceleration in the timing of the expenses.

Revenue Recognition. We sell our products through a combination of a direct sales force in the U.S. and certain European countries and through distributors elsewhere. We recognize revenue when title to the goods and risk of loss transfer to our customers, providing there are no remaining performance obligations required of us

or any matters requiring customer acceptance. We record estimated sales returns and discounts as a reduction of net sales in the same period revenue is recognized. Our revenues are dependent upon sales to new and existing customers pursuant to our current policies. Changes in these policies or sales terms could impact the amount and timing of revenue recognized.

Research and Development. All research and development costs are expensed as incurred. We have entered into contractual obligations for the conduct of clinical studies. Costs are incurred primarily at the time of enrollment and paid under the terms of the contracts. Research and development expenses could vary significantly with changes in the timing of clinical activity.

Stock Options. We have adopted the disclosure-only provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” and SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” which disclosures are presented in Note 2, “Stock Incentive and Purchase Plan.” Because of this election, we continue to account for our employee stock-based compensation plans under APB Opinion No. 25 and the related interpretations. We are required to comply with SFAS No. 123 (revised 2004) starting on the first day of our fiscal year 2007 or April 29, 2006. We are currently evaluating the effect that the adoption of SFAS No. 123 (revised 2004) will have on our consolidated operating results and financial condition. No stock-based compensation cost is currently reflected in net income for employee option grants as most options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. There is only one exception further disclosed under Note 9 of our Consolidated Financial Statements, whereby deferred compensation is recorded for certain stock-based compensation grants based on the excess of the market value of the common stock on the measurement date over the exercise price. The deferred compensation is amortized over the vesting period of each unit of stock-based compensation.

Income Taxes. We account for income taxes under the asset and liability method. Under this method, deferred income taxes reflect the impact of temporary differences between financial accounting and tax basis of assets and liabilities. Such differences relate primarily to the deductibility of certain accruals and reserves and the effect of tax loss and tax credit carryforwards not yet utilized. Deferred tax assets are evaluated for realization based on a more-likely-than-not criterion in determining if a valuation allowance should be provided.

Reclassifications. Certain reclassifications have been made to prior period consolidated financial statements to conform with the current period’s presentation.

Results of Operations

Net Sales

During the thirteen weeks ended October 28, 2005, U.S. net sales increased by 11% as compared to the thirteen weeks ended October 29, 2004. Unit sales volume increased by 8% and average system prices increased by 3% largely resulting from changes in product mix. During the twenty-six weeks ended October 28, 2005, U.S. sales increased by 8% as compared to the twenty-six weeks ended October 29, 2004. Unit sales volume increased by 6% and average system prices increased by 2% largely resulting from changes in product mix.

International sales for the thirteen weeks ended October 28, 2005 increased by 36% over the same period last year due to an increase in sales volume of 30% and an increase in average system prices of 5%, largely due to favorable currency impact and changes in country and product mix. International sales for the twenty-six weeks ended October 28, 2005 increased by 33% as compared to the twenty-six weeks ended October 29, 2004 due to increases in volume of 24% and increases in average selling prices of 7%, largely due to favorable currency impact and changes in product and country mix.

Gross Profit

Gross profit margin for the thirteen weeks ended October 28, 2005 was 87.0% representing an increase of 160 basis points over the same period last year. Increase in manufacturing efficiencies due to higher production volume provided an improvement of 170 basis points, offset by changes in the mix between domestic and international sales which reduced gross profit margin by 10 basis points.

Gross profit margin for the twenty-six weeks ended October 28, 2005 was 86.5% representing an increase of 330 basis points over the same period last year. Increased manufacturing efficiencies associated with the ramp up of production for the product launch in TRD improved net profit margin by 290 basis points and favorable changes in product mix further improved gross profit margin by 40 basis points.

Cost of sales consists primarily of direct labor, allocated manufacturing overhead, third-party contractor costs, royalties and the acquisition cost of raw materials and components. We are obligated to pay royalties at rates of about 3% of net sales in future periods. Gross margins can be expected to fluctuate in future periods based upon the mix between U.S. and international sales, direct and distributor sales, the VNS Therapy System selling price, applicable royalty rates, and the levels of production volume.

Operating Expenses

Selling, General and Administrative (SG&A) Expenses. SG&A expenses are comprised of sales, marketing, development, general and administrative activities. SG&A expenses increased by 111% for the thirteen weeks ended October 28, 2005, as compared to the thirteen weeks ended October 29, 2004. For the twenty-six weeks ended October 28, 2005, SG&A expenses increased by 102% as compared to the same period last year. The increases in expenses for the thirteen and twenty-six weeks are largely due to sales, marketing and administrative activities in support of the TRD depression launch and expanded corporate administrative functions associated with increased compliance requirements.

Research and Development (R&D) Expenses. R&D expenses are comprised of expenses related to our product and process development, product design efforts, clinical trials programs and regulatory activities. As compared to prior year, R&D expenses increased by 58% for the thirteen weeks ended October 28, 2005 and increased by 45% for the twenty-six weeks ended October 28, 2005, due to expanded clinical and regulatory activities supporting the completion of the U.S. regulatory process for obtaining approval of VNS Therapy in TRD, ongoing product development activities and expanded clinical and regulatory activities in epilepsy, depression and new indications programs.

Interest Income and Expense

Interest income for the thirteen weeks ended October 28, 2005 increased by 178% over the same period last year as a result of higher invested cash balances from the proceeds of our convertible notes offering completed during the quarter earning higher interest rates. Interest expense for the thirteen weeks ended October 28, 2005 increased by 339% over the same period last year due to the interest on the notes payable partially offset by lower interest expense caused by no borrowings against our $20 million line of credit facility which expired in September 2005 and reductions in interest expense on capital leases for manufacturing equipment.

Interest income for the twenty-six weeks ended October 28, 2005 increased by 175% due to higher invested cash balances from the proceeds of our convertible notes offering completed during the quarter earning higher interest rates. Interest expense for the twenty-six weeks ended October 28, 2005 increased by 146% due to interest payable on the notes payable, partially offset by lower interest expense caused by lower borrowings against our credit facility which expired in September 2005.

Other Income, Net

Other income, net, primarily includes income related to the over-allotment provision applicable to the 2005 bond offering and transaction gains and losses associated with the impact of changes in foreign currency exchange rates.

Income Taxes

We estimate that our effective tax rate for the thirteen weeks ended October 28, 2005 to be less than 1%, due primarily to the increase in the balance of our valuation allowance combined with state tax and tax on foreign operations. The effective tax rate represents our estimate of the rate expected to be applicable for the full fiscal year. In August 2004, we experienced an ownership change as defined in Section 382 of the Internal Revenue Code (IRC). Our ability to utilize certain net operating losses to offset future taxable income in any particular year may be limited pursuant to IRC Section 382. Due to our operating loss history and possible limitations pursuant to IRC Section 382, we have established a valuation allowance that fully offsets our net deferred tax assets, including those related to tax loss carry-forwards, resulting in no regular U.S. federal income tax expense or benefit for financial reporting purposes.

Liquidity and Capital Resources

Key performance indicators used by management to assess our liquidity are as follows:


	Thirteen Weeks Ended
	October 28, 2005			October 29, 2004
	(Unaudited)			(Unaudited)
Cash, Cash Equivalents and Marketable Securities at Quarter End	$	118,914,091		$	54,458,773
Line of Credit		—			3,000,000
Net Cash Used in Operating Activities		(39,499,130	)		(913,000	)
Net Cash Provided by (used in) Financing Activities		99,468,527			(1,672,207	)

During the twenty-six weeks ended October 28, 2005, cash, cash equivalents and short-term marketable securities increased by $57,438,000 to $118,914,000. In September 2005, we issued $125,000,000 of senior subordinated convertible notes payable which provided net proceeds of approximately $121 million. We used the proceeds for (1) a simultaneous share buyback of 301,000 shares at $33.20 per share for a total of $9,993,200; (2) the net cost of $13,000,000 of separate convertible bond hedge and common stock warrant transactions resulting in net cash proceeds of $98,257,000. We also received approximately $4,811,000 in connection with the issuance of shares pursuant to our stock option and employee stock purchase plans during the twenty-six weeks ended October 28, 2005. Net cash used by operating activities was $39,499,000 compared to $913,000 during the same period last year. The increase in cash used in operating activities was primarily the result of the increase in net loss relating to our investment in the U.S. TRD launch in fiscal year 2006 and related increases in accounts receivable, inventories and accrued liabilities in the current period as compared to the same period last year. In September 2005, we elected not to renew our $20,000,000 line of credit. We continue to evaluate the advantages of maintaining an asset-based line of credit and may re-establish a similar line of credit in the future.

We are party to a number of contracts pursuant to which we are paying for clinical studies for current operating obligations payable totaling about $1.4 million as of October 28, 2005. Although we have no firm commitments, we expect to make capital expenditures of approximately $8 million during fiscal year 2006 primarily to expand manufacturing capabilities and to enhance business infrastructure and facilities.

The chart below reflects our current obligations under our material contractual obligations.

We believe our current cash, cash equivalents and capital resources will be sufficient to fund our current levels of operating needs and capital expenditures throughout fiscal 2007. Our liquidity could, however, be adversely affected by the “Factors Affecting Future Operating Results” discussed below.

Impact of New Accounting Pronouncements

See Note 12 of Notes to Consolidated Financial Statements for a discussion of the impact of new accounting pronouncements.

Factors Affecting Future Operating Results

In addition to the factors described above in this section and in the section of our Annual Report on Form 10-K entitled “Business,” the following additional factors could affect our future results and, as a result, our common stock price.

Our common stock price constantly changes. Our common stock is traded on the NASDAQ National Market under the ticker symbol “CYBX.” The price of stock on that trading market fluctuates, and we expect that the market price of common stock will continue to fluctuate. For instance, during the 52 weeks ended October 28, 2005, our stock has traded from a high of $47.77 to a low of $18.10 per share. The fluctuation in our stock price is caused by a number of factors, some of which are beyond our control, including:

	•		quarterly variations in our sales and operating results;

	•		regulatory activities and announcements;

	•		results of studies regarding the efficacy of our VNS Therapy treatment for various indications including epilepsy, depression, Alzheimer’s Disease, anxiety and other disorders;

	•		announcements of significant contracts, acquisitions, or capital commitments;

	•		changes in financial estimates by securities analysts;

	•		changes in market valuations of medical device companies;

	•		additions or departures of key personnel;

	•		sales or purchases of common stock by us, our officers and members of our Board of Directors; and

	•		changes in the general conditions of the economy.

In addition, the stock market in recent years has experienced broad price and volume fluctuations that have often been unrelated to the operating performance of companies. These broad market fluctuations have also adversely affected, and may continue to adversely affect, the market price of our common stock.

Our quarterly operating results may fluctuate in the future, which may cause our stock price to decline. Our consolidated results of operations may fluctuate significantly from quarter to quarter and may be below the expectations of security analysts. If so, the market price of our shares may decline. Our quarterly revenues, expenses and operating results may vary significantly from quarter to quarter for several reasons, including the extent to which the VNS Therapy System gains market acceptance, the timing of obtaining marketing approvals for the VNS Therapy System for other indications, the timing of any approvals for reimbursement by third-party payers, the rate and size of expenditures incurred as we expand our clinical, manufacturing, sales and marketing efforts, our ability to retain qualified sales personnel and the availability of key components, materials and contract services, which may depend on our ability to forecast sales.

We rely solely on sales of VNS Therapy Systems for our revenues and if sales of these Systems are not achieved for either epilepsy or depression, our operating results will be severely harmed. Our product portfolio is limited to VNS Therapy Systems for two indications: as an adjunctive therapy in reducing the frequency of seizures in adults and adolescents over 12 years of age with partial onset seizures that are refractory to antiepileptic drugs and as a long-term adjunctive treatment of chronic or recurrent depression for patients 18 years or older who are experiencing a major depressive episode and have not had an adequate response to four or more antidepressant treatments. We cannot assure you that sales of the VNS Therapy System for the treatment of epilepsy will increase. In addition, we are currently limited to case-by-case approvals for reimbursement of the VNS Therapy System for the treatment of depression in the U.S. We cannot assure you that we will receive broader reimbursement approvals or otherwise be successful in commercializing the VNS Therapy System for the treatment of depression. The same uncertainty surrounds our efforts in anxiety disorders, Alzheimer’s Disease applications and other indications for which we currently do not have FDA approvals. Our inability to successfully commercialize the VNS Therapy System for depression and other indications could severely harm our future growth.

We may experience difficulties and delays in the manufacturing, marketing and sale of our VNS Therapy System. We are subject to extensive and rigorous ongoing regulation of the research, development, testing, manufacture, labeling, promotion, advertising, distribution and marketing of our product. Our failure to comply with these requirements or the identification of manufacturing or safety problems during commercial marketing could lead to the need for product marketing restrictions, product withdrawal or recall or other voluntary or regulatory action, which could delay further marketing until the product is brought into compliance. Our failure to comply with these requirements may also subject us to stringent penalties.

Our indebtedness and debt service obligations may adversely affect our cash flow, cash position and stock price. As of October 28, 2005, we had approximately $125 million in long-term convertible debt and aggregate annual debt service obligations on this debt of approximately $3.8 million. If we issue other debt securities in the future, our debt service obligations and interest expense will increase further. We intend to fulfill our debt service obligations from earnings and our existing cash and investments. In the future, if we are unable to generate cash or raise additional cash through financing sufficient to meet these obligations and need to use existing cash or liquidate investments in order to fund these obligations, we may have to delay or curtail research, development and commercialization programs. Our indebtedness could have significant additional negative consequences, including, without limitation:

	•		requiring the dedication of a portion of our cash to service our indebtedness and to pay off the principal at maturity, thereby reducing the amount of our expected cash available for other purposes, including funding our research, development and commercialization efforts and capital expenditures;

	•		increasing our vulnerability to general adverse economic conditions;

	•		limiting our ability to obtain additional financing; and

	•		placing us at a possible competitive disadvantage to less leveraged competitors and competitors with better access to capital resources.

Upon the occurrence of a fundamental change, holders of our senior subordinated convertible notes may force us to purchase their notes at the full amount owed thereunder including accrued but unpaid interest. If we undergo a fundamental change, including, but not limited to, the acquisition by any person of the beneficial ownership of 50% of the voting stock, our consolidation or merger with or into any other person, our liquidation, or our common stock being removed from listing on NASDAQ, holders of the senior subordinated convertible notes may, at their option, require us to purchase their notes for the full amount owed thereunder including accrued but unpaid interest. Such amount may be greater than their value at the time of repurchase. As a result, the possibility of such repurchase requirement may inhibit the consummation of certain transactions such as mergers that may be beneficial to our stockholders.

Upon the occurrence of certain events, the initial conversion rate of our senior subordinated convertible notes will be adjusted, which could result in an increased number of shares being issued upon conversion. The initial conversion rate of our senior subordinated convertible notes will be adjusted upon the occurrence of certain events, including, among others, the issuance to holders of our common stock of certain rights to purchase our common stock at less than the current market price of our common stock or the issuance of cash dividends to substantially all of our common stockholders. Should the conversion rate be adjusted, holders of our senior subordinated convertible notes would receive a greater number of shares of our common stock per note, resulting in increased percentage ownership of our common stock by the former noteholders.

We may need significant additional capital. Our capital requirements may be substantial and will depend on many factors, including market acceptance of our product and clinical and strategic development opportunities. A large portion of our expenses is currently fixed, including expenses related to our facilities and equipment and we expect to spend significant amounts to market our product for the treatment of depression. As a result, we expect that our operating expenses will exceed revenues in the first full year after U.S. approval of the VNS Therapy for depression. Consequently, we will need to generate significant additional revenues to achieve profitability in the future. Even if we do achieve profitability, we may not be able to increase profitability on a quarterly or annual basis. Furthermore, if additional capital is required, we may not be able to access sufficient sources or to access capital on terms which are acceptable to us.

We may not be successful in our efforts to develop VNS Therapy for the treatment of bulimia, Alzheimer’s Disease, anxiety or any other indications. We are in the process of conducting or supporting studies to help us evaluate, and potentially obtain FDA approval, for the use of VNS Therapy as a treatment for bulimia, Alzheimer’s Disease, anxiety and other neurological disorders. We cannot assure you that our study results will be positive or that we will receive FDA approval for the use of our product for the treatment of any other indication. Even if we receive FDA approval for another indication, we can provide no assurances with respect to market acceptance. If our study results are not as we anticipate or if we receive no additional FDA approvals or if alternative indications do not prove to be commercially viable, our revenues may not experience the growth that we would anticipate with the successful development of any of these indications.

We may not be able to expand or maintain market acceptance of the use of the VNS Therapy System to treat epilepsy or depression, which could cause our sales to be lower than expectations. Market acceptance of the VNS Therapy System will depend on our ability to convince the medical community of the clinical efficacy and safety of vagus nerve stimulation and the VNS Therapy System. While the VNS Therapy System has been

implanted in approximately 32,000 patients, many physicians are still unfamiliar with this form of therapy. We believe that existing pharmacological therapies and surgery are the only other approved and currently available therapies competitive with the VNS Therapy System. These therapies may be more attractive to patients or their physicians than the VNS Therapy System in terms of efficacy, cost or reimbursement availability. Furthermore, we have not funded significant post-market clinical research that will change physicians’ opinions or use of our product. We cannot assure you that sales will increase. We cannot assure you that the VNS Therapy System will achieve expanded market acceptance for the treatment of epilepsy, depression or for any other indication. Failure of the VNS Therapy System to gain additional market acceptance would severely harm our business, financial condition and results of operations.

We may not be successful in our marketing and sales efforts, which could severely harm our business. We launched VNS Therapy for TRD in August 2005 following expansion of our sales and case management organization to support anticipated sales demand in both epilepsy and depression markets. While we expect the recent approval of VNS Therapy in TRD to result in revenue growth in fiscal 2006, we can provide no assurance in that regard. In addition, other factors affecting market acceptance may significantly affect the size and structure of our sales organization and the effectiveness of our sales and marketing efforts. Accordingly, improvements in sales force productivity are not expected in fiscal 2006, as we are planning to support product launch activities in depression throughout fiscal 2006. Furthermore, our expectations for potential sales demand in a completely new device market for TRD will likely change as we complete our physician targeting programs and promote awareness and acceptance of VNS Therapy among new psychiatric prescribers. The time necessary for our expanded sales organization to establish new territories and relationships of trust with new physicians may take longer than projected, which could substantially delay improvements in U.S. sales performance or jeopardize attainment of quarterly revenue goals. Our inability to achieve annual or quarterly revenue targets could substantially harm our consolidated results of operations and financial condition.

Patient confidentiality and federal and state privacy laws and regulations may adversely impact our patient pull-through selling model. The HIPAA Privacy Rule became effective in April 2003 and the HIPAA Security Rule became effective in April 2005. In addition, virtually every state has enacted one or more laws to safeguard privacy, and these laws vary significantly from state to state and change frequently. The HIPAA Privacy Rule preempts a state privacy law only if the state privacy law is narrower in scope than the HIPAA Privacy Rule. Consequently, the applicable privacy rules can vary state by state, and the determination of the privacy rules applicable in any one state can be very difficult. In addition, prior to the HIPAA Privacy Rule, most states enacted statutes protecting the privacy of the mental health patients. Consequently, psychiatrists have long been sensitive to the confidentiality of mental health patients and their medical records. The operation of our business involves the collection and use of substantial amounts of “protected health information,” including patient information provided by physicians to assist in the treatment of patients, information provided by patients themselves to assist them in scheduling surgery and confirming their eligibility for third-party reimbursement, patient information provided by hospitals in connection with their efforts to obtain third-party reimbursement, patient information collected by our Product Performance Department in the investigation of product complaints and the tracking of implanted devices. We endeavor to conduct our business as a “covered entity” under the HIPAA Privacy Rule and consistent with the Texas privacy laws, obtaining HIPAA-compliant patient authorizations where required to support the collection and use of patient information. We also sometimes act as a “business associate” for a covered entity. For example, we sometimes provide assistance to hospitals (covered entities) in connection with their requests for third-party reimbursement of VNS Therapy Systems and procedures. Even if our business model is compliant with the HIPAA Privacy Rule and the Texas privacy laws, it may not be compliant with the privacy laws of all states. In addition, despite extensive efforts to conduct our business as a covered entity under the HIPAA Privacy Rule and the Texas privacy laws, the Office of the Inspector General of the Department of Health and Human Services or another government enforcement agency may determine that we are obligated to comply with the HIPAA Privacy Rule or another law and that our business model or operations are not in compliance with such law, which could subject us to penalties and could severely limit our ability to market and sell VNS Therapy under our existing business model and could harm our business growth and financial condition.

We may be unable to obtain and maintain adequate third-party reimbursement on our product. Our ability to commercialize the VNS Therapy System successfully depends in part on whether third-party payers, including private healthcare insurers, managed care plans, Medicare and Medicaid programs and others, agree both to cover the VNS Therapy System and associated procedures and services and to reimburse at adequate levels for the costs of the VNS Therapy System and the related services in the U.S. or internationally. While we currently have reimbursement approval for epilepsy, we have not yet received broad approval for the treatment of depression. If we fail to maintain or expand favorable coverage decisions for the VNS Therapy System in a timely manner, patients and their physicians could be deterred from using the VNS Therapy System, which could reduce our sales and severely harm our business.

Our current and future expense estimates are based, in large part, on estimates of future sales, which are difficult to predict. We may be unable to, or may elect not to, adjust spending quickly enough to offset any unexpected sales shortfall. If increased expenses are not accompanied by increased sales, our consolidated results of operations and financial condition for any particular quarter could be harmed.

If our suppliers and manufacturers are unable to meet our demand for materials, components and contract services, we may be forced to qualify new vendors or change our product design which would impair our ability to deliver products to our customers on a timely basis. We rely upon sole source suppliers for certain of the key components, materials and contract services used in manufacturing the VNS Therapy System. We periodically experience discontinuation or unavailability of components, materials and contract services which may require us to qualify alternative sources or, if no such alternative sources are identified, change our product design. We believe that pursuing and qualifying alternative sources and/or redesigning specific components of the VNS Therapy System, if or when necessary, could consume significant resources. In addition, such changes generally require regulatory submissions and approvals. Any extended delays in or an inability to secure alternative sources for these or other components, materials and contract services could result in product supply and manufacturing interruptions, which could significantly harm our business.

Our products may be found to have defects that result in product recalls. The VNS Therapy System includes an electronic pulse generator and lead designed to be implanted in the human body. Component failures, manufacturing or shipping problems or design defects could result in the product not delivering the therapy for which it is indicated. The occurrence of such problems or other adverse clinical reactions could result in a recall of our products, possibly requiring explantation and potential reimplantation of the VNS Therapy System, which may increase risk to the patient. Any product recall could severely harm our business and our consolidated financial condition and results of operations.

We may not be able to protect our technology from unauthorized use, which could diminish the value of our products and impair our ability to compete. Our success depends upon our ability to obtain and maintain patent and other intellectual property protection for the VNS Therapy System and its improvements, and for vagus nerve stimulation therapy. To that end, we have acquired licenses under certain patents and have patented and intend to continue to seek patents on our own treatment methods and other inventions used in our products. The process of seeking patent protection can be expensive and time consuming, and we cannot assure you that patents will be issued from our currently pending or future applications or that, if patents are issued, they will be of sufficient scope or strength to provide meaningful protection for our technology or any commercial advantage to us. Further, the protection offered by the international patents is not as strong as that offered by the U.S. patents due to differences in patent laws. In particular, the European Patent Convention prohibits patents covering methods for treatment of the human body by surgery or therapy.

We may engage in litigation to protect our proprietary rights, or defend against infringement claims by third parties, causing us to suffer significant expenses or prevent us from selling our products. There has been substantial litigation regarding patent and other intellectual property rights in the medical device industry. Litigation, which could result in substantial cost to and diversion of effort by us, may be necessary to enforce patents issued or licensed to us, to protect trade secrets or know-how owned by us or to defend ourselves against claimed infringement of the rights of others and to determine the scope and validity of the proprietary rights of others. Adverse determinations in litigation could subject us to significant liabilities to third parties, could

require us to seek licenses from third parties and could prevent us from manufacturing, selling or using the VNS Therapy System, any of which could severely harm our business.

Intense competition and rapid technological changes could reduce our ability to market our products and achieve sales. We believe that existing and future pharmaceutical therapies will continue to be the primary competition for the VNS Therapy System. We may also face competition from other medical device companies that have the technology, experience and capital resources to develop alternative devices for the treatment of epilepsy and depression. Many of our competitors have substantially greater financial, manufacturing, marketing and technical resources than we do and have obtained third-party reimbursement approvals for their therapies. In addition, the healthcare industry is characterized by extensive research efforts and rapid technological progress. Our competitors may develop technologies and obtain regulatory approval for products that are more effective in treating epilepsy and depression than our current or future products. In addition, advancements in surgical techniques may make surgery a more attractive therapy for epilepsy and depression. The development by others of new treatment methods with novel drugs, medical devices or surgical techniques for epilepsy and depression could render the VNS Therapy System non-competitive or obsolete. We may not be able to compete successfully against current and future competitors, including new products and technology, which could severely harm our business and our consolidated financial condition and results of operations.

We are subject to claims of product liability and we may not have the resources or insurance to cover the cost for losses under these claims. As an implantable medical device, the manufacture and sale of the VNS Therapy System entails the risk of product liability claims, which we have received from time to time in the ordinary course of business. We may be responsible for large deductibles for each claim, and our product liability coverage may not be adequate to cover judgments that may result from these claims. Product liability insurance is expensive and in the future may only be available at significantly higher premiums or not be available on acceptable terms, if at all. A successful claim brought against us in excess of our insurance coverage could significantly harm our business and financial condition.

If we do not continue to comply with changing government laws and regulations, we could lose our ability to market and sell our product or be subject to substantial fines or other penalties. The preclinical and clinical testing, manufacturing, labeling, sale, distribution and promotion of the VNS Therapy System are subject to extensive and rigorous federal and state laws and regulations, including regulations from the Department of Health and Human Services (related to Medicare, HIPAA and FDA) and from comparable state agencies. In the future, it will be necessary for us to obtain additional government approvals for other applications of the VNS Therapy System and for modified or future-generation products. On July 22, 2005, Cyberonics received a “medical device tracking order” from FDA. This is a routine FDA requirement for a manufacturer to adopt a method of tracking an implanted device to a named patient. It will also be necessary for us to ensure that our marketing and sales practices comply with all laws and regulations. Commercial distribution in certain foreign countries is also subject to regulatory approvals from the appropriate authorities in such countries. The process of obtaining FDA and other required regulatory approvals is lengthy, expensive and uncertain. Moreover, regulatory approvals may include regulatory restrictions on the indicated uses for which a product may be marketed. Failure to comply with applicable regulatory requirements can result in, among other things, fines, suspension or withdrawal of approvals, confiscations or recalls of products, operating restrictions and criminal prosecution. Furthermore, changes in existing regulations or adoption of new regulations could prevent us from obtaining, or affect the timing of, future regulatory approvals. We may not be able to obtain additional future regulatory approvals on a timely basis or at all. Delays in receipt of or failure to receive such future approvals, suspension or withdrawal of previously received approvals or recalls of the VNS Therapy System could severely harm our ability to market and sell our current and future products and improvements.

We are subject to federal and state laws governing our sales and marketing practices, and failure to adhere to these laws could result in substantial fines and other penalties. We are subject to certain laws and regulations, including the federal Anti-Kickback Statute and the HIPAA Privacy Rule, that govern the sales and marketing practices of healthcare companies. In 2004, we adopted a healthcare law compliance program, including our Business Practice Standards, which is a set of policies that embody the AdvaMed Code of Ethics for Interactions with Health Care Professionals. We endeavor to conduct our business in compliance with our Business Practice

Standards and to ensure continued compliance through regular education of the Company’s employees and regular audits of employee activities. Although we believe that these efforts have been successful and that we are in compliance with our policies and the healthcare laws, given the complexity of our patient pull-through business model, including extensive interactions with patients and healthcare professionals, and the large number of field personnel employed by the Company, violations of our policy and the law could occur. We could be subject to investigation by the Office of the Inspector General of the Department of Health and Human Services or the Department of Justice. If investigated, we could be forced to incur substantial expense responding to the investigation and defending our actions. If unsuccessful in our defense, we could be found to be in violation of the healthcare laws and be subject to substantial fines and penalties, including exclusion of our products from Medicare and Medicaid reimbursement.

Our international operations are subject to risks not generally associated with commercialization efforts in the U.S. We may not be successful in increasing our international market sales or in obtaining reimbursement or any regulatory approvals required in foreign countries. The anticipated international nature of our business is also expected to subject us and our representatives, agents and distributors to laws and regulations of the foreign jurisdictions in which we operate or where the VNS Therapy System is sold. The regulation of medical devices in a number of such jurisdictions, particularly in the European Union, continues to develop and new laws or regulations may impair our ability to market and sell our products in those jurisdictions.

If we fail to manage our growth effectively, our ability to maintain our costs or capture new business could suffer. In connection with the commercialization of the VNS Therapy System in the U.S. for TRD, we have begun and intend to continue to expand significantly the scope of our operations. Such activities have placed, and may continue to place a significant strain on our resources and operations. Our ability to manage such growth effectively will depend upon our ability to attract, hire and retain highly qualified employees and management personnel. We compete for such personnel with other companies, academic institutions, government entities and other organizations and we may not be successful in hiring or retaining qualified personnel. Our success will also depend on the ability of our officers and key employees to continue to implement and improve our operational, management information and financial control systems. If we fail to manage our growth effectively, our business will suffer.

We received a letter from the Senate Finance Committee (SFC) in May 2005 advising us that it is examining FDA’s handling of our PMA-Supplement for the use of VNS Therapy to address treatment-resistant depression. The SFC’s letter requested that we provide the SFC with certain documents and information. We received a second letter from the SFC in July 2005 also requesting documents and information. We believe that we have provided all documents and information requested by the SFC. Responding to any further requests by the SFC could divert the efforts and attention of our management team. We are unable to provide assurance as to the time it will take for the SFC to complete its review or of such review’s ultimate consequence, if any.

We have been named in a putative class action shareholder lawsuit. The Company and certain of its officers have been named as defendants in a putative class action lawsuit. A discussion of this lawsuit is contained in Part II, “Item 1. Legal Proceedings.” Although it is not possible at this early stage to predict the likely outcome of this litigation, an adverse result could have a material adverse effect on us, our consolidated financial condition, results of operations and cash flows.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to limited market risk on interest rates and foreign currency exchange rates.

Our exposure to market risk for changes in interest rates relates primarily to our short-term investments in commercial paper. We do not hedge interest rate exposure or invest in derivative securities. Based upon the average outstanding balances in cash and cash equivalents, a 100-basis point change in interest rates would not have a material impact on our financial results.

Due to the global reach of our business, we are also exposed to market risk from changes in foreign currency exchange rates, particularly with respect to the U.S. dollar compared to the Euro. Our wholly owned foreign subsidiary is consolidated into our financial results and is subject to risks typical of an international business including, but not limited to, differing economic conditions, changes in political climate, differing tax structures, other regulations and restrictions and foreign exchange rate volatility. Accordingly, our future results could be materially impacted by changes in these or other factors. At this time, we have not deemed it to be cost effective to engage in a program of hedging the effect of foreign currency fluctuations on our operating results using derivative financial instruments. A sensitivity analysis indicates that, if the U.S. dollar uniformly weakened 10% against the Euro, the effect upon net loss for the thirteen weeks ended October 28, 2005 would have been favorable by approximately $269,000 or 1.2%. Conversely, if the U.S. dollar uniformly strengthened 10% against the Euro, the impact on net loss for the thirteen weeks ended October 28, 2005 would have been unfavorable by approximately $249,000 or 1.1%. For the twenty-six weeks ended October 28, 2005, using the same 10% parameter in our sensitivity analysis, the favorable impact would have been $520,000 or 1.3% and $461,000 or 1.1% unfavorable.

ITEM 4. CONTROLS AND PROCEDURES

We maintain a system of disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities and Exchange Act of 1934) designed to ensure that we are able to record, process, summarize and report, within the applicable time periods, the information required in our annual and quarterly reports under the Securities Exchange Act of 1934.

As of the end of the period covered by this report, an evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective. In addition, there have been no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during our last fiscal year that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On June 17, 2005, a putative class action lawsuit was filed against Cyberonics and certain of its current officers in the United States District Court for the Southern District of Texas. The lawsuit is styled Richard Darquea v. Cyberonics Inc., et al., Civil Action No. H:05-cv-2121. A second lawsuit with similar allegations, styled Stanley Sved v. Cyberonics, Inc. et al., Civil Action No. H:05-cv-2414 was filed on July 12, 2005. On July 28, 2005, the Court consolidated the two cases under Civil Action No. H-05-2121, styled In re Cyberonics, Inc. Securities Litigation, and entered a scheduling order. On September 28, 2005, the court appointed lead plaintiffs and lead counsel.

named as defendants, who purchased or otherwise acquired Cyberonics securities during the period June 15, 2004 through October 1, 2004. The complaint seeks unspecified monetary damages and equitable or injunctive relief, if available.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On September 27, 2005 the Company issued $125 million of seven-year senior subordinated convertible notes. The notes were priced to yield 3.0 percent. The initial purchaser was Merrill Lynch & Co. In connection with the sale of the notes, the Company purchased approximately 300,000 shares of its common stock and entered into separate convertible bond hedge and warrant transactions with an affiliate of the initial purchaser. After purchase of the shares of common stock, payments for the convertible bond hedge and warrant transactions and payment of all other related fees and expenses, the net proceeds from the sale of the notes were approximately $98 million. The notes were issued pursuant to an exemption from registration under Rule 144A. The notes were sold only to institutional investors in compliance with Rule 144A. The notes may be converted at any time into 24.0964 shares of common stock per $1,000 of principal amount, which is equal to a conversion price of approximately $41.50. The conversion rate is subject to adjustment as provided in the notes. The conversion rate will be adjusted for, among other events, issuance of Company common stock as a dividend, subdivisions or combinations of Cyberonics’s common stock, cash dividends, and the issuance to all stockholders of rights to purchase the common stock at less than the then current market price.
