PART I - Financial Information

Item 1. Financial Statements

The following condensed consolidated balance sheet as of December 31, 2005, which has been derived from audited financial statements and the unaudited interim condensed consolidated financial statements, consisting of the condensed consolidated balance sheet as of September 30, 2006, the condensed consolidated statements of operations for the three and nine month periods ended September 30, 2006 and 2005, and the condensed consolidated statements of cash flows for the nine month periods ended September 30, 2006 and 2005, have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading.

The following condensed balance sheet as of December 31, 2005, which has been derived from audited financial statements does not include all of the information and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. It is suggested that these condensed financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. In the opinion of management, these unaudited statements contain all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation for the periods presented as required by Regulation S-X, Rule 10-01 in these unaudited statements.

Actual results could differ from those estimates and operating results for the three and nine month periods ended September 30, 2006 and are not necessarily indicative of the results that may be expected for any subsequent period or for the year ending December 31, 2006.

Note 2 – Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements include the accounts of Maxwell Technologies, Inc. and its subsidiaries. All significant intercompany transactions and account balances are eliminated in consolidation.

In the opinion of management of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows of Maxwell Technologies, Inc. for all periods presented. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for any subsequent period or for the entire year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s latest annual report on Form 10-K. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been condensed or omitted.

The preparation of financial statements in conformity with U.S. - GAAP requires management to make estimates and assumptions that affect reported amounts and related disclosures. Estimates have been prepared on the basis of the most current information available. These estimates include assessing the collectability of accounts receivable, the usage and recoverability of inventories and long-lived assets and the incurrence of losses on warranty costs, the fair value of warrants and embedded conversion options related to convertible debentures, and vacant leased facilities. The markets for most of the Company’s products are extremely competitive and are characterized by rapid technological change, new product development, product obsolescence and evolving industry standards. In addition, price competition is intense and significant price erosion generally occurs over the life of a product. As a result of these issues noted and other factors, actual results could differ from the estimates used by management.

The Company’s fiscal quarters end on the last day of the calendar month in March, June, September, and December.

Cash and Cash Equivalents, Investments in Marketable Securities

The Company invests its excess cash in debt instruments of the U.S. Government and its agencies; bank certificates of deposit; commercial paper/ and high-quality corporate issuers. All highly liquid instruments with an original maturity of three months or less from purchase are considered cash equivalents, and those with original maturities greater than three months on the date of purchase are considered investments in marketable securities. The Company’s investments in marketable securities are classified as available-for-sale and are reported at fair value, with unrealized gains and losses included in stockholders’ equity as a separate component of accumulated other comprehensive income. Realized gains or losses and other-than-temporary declines in value, if any, on available-for-sale securities are reported in other income or expense as incurred. The Company recognized zero, in net realized gains in the period ended September 30, 2006 and for the year ended December 31, 2005. The Company uses the specific identification method on sales of investments.

Maturities and gross unrealized gains on investments in marketable securities at September 30, 2006 and December 31, 2005 are as follows (in thousands):

Revenue Recognition

We derive substantially all of our revenue from the sale of manufactured products. Product revenue is recognized, according to the guidelines of SEC Staff Accounting Bulletin Numbers 101 Revenue Recognition in Financial Statements, and 104 Revenue Recognition, when title passes to the customer at either shipment from our facilities, or receipt at the customer facility, depending on shipping terms, provided collectability is reasonably assured. This method has been consistently applied from period to period and there is no right of return. Revenue on fixed price government contracts is recognized at the time costs are incurred and is calculated on a percentage of completion basis, in accordance with Statement of Position 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts and is limited by the funding of the prime contractor. In prior years, certain continuing and discontinued segments involved revenues from both long-term and short-term fixed price contracts and cost plus contracts with the U.S. Government directly or through a prime contractor. Those revenues, including estimated profits, were recognized at the time the costs were incurred and included provisions for any anticipated losses. These contracts are subject to rate audits and other audits, which could result in the reduction of revenue in excess of estimated provisions. In turn, this could increase losses for the periods in which any such reduction occurs. In the three and nine months ended September 30, 2006 the Company recognized revenue that relates to specific deliverables, in accordance with EITF 00-21, Accounting for Revenue Arrangements with Multiple Deliverables. This revenue involves a contract that grants a license to manufacture and market ultracapacitor products in Mainland China, using Maxwell’s proprietary large cell and multi-cell module technology under a separate brand. The contract, obligates the manufacturer to source ultracapacitor electrode material from Maxwell, the agreement has no general right of return and requires no refunds.

Computation of Net Loss per Share

Basic loss per share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Diluted loss per share is calculated on the basis of the weighted average number of common shares outstanding plus the dilutive effect of outstanding stock options and restricted stock awards of the Company, assuming their exercise using the “treasury stock” method.

The following table sets forth the computation of basic and diluted loss per share (in thousands, except per share data):

For the three and nine-month periods ended September 30, 2006 and 2005, incremental equivalent shares under common stock options and restricted stock awards of 1,104,472 and 1,133,298 for 2006, and 1,146,860 and 885,054 for 2005, respectively, were not included in the computation of diluted earnings per share as their impact would have been anti-dilutive. Shares issuable on conversion of convertible debentures of 1,315,790 have also been excluded in the computation of dilutive earnings per share as their impact would have been anti-dilutive.

Stock Option Plans

The Company has two active stock-based employee compensation plans as of September 30, 2006, which are described more fully in Note 4. Prior to January 1, 2006, the Company had accounted for stock-based employee compensation by the disclosure only provisions of Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148 Accounting for Stock Based Compensation—Transitions and Disclosure. In accordance with the provisions of SFAS No. 123, the Company applied Accounting Principles Board Opinion No. 25 (APB 25) and related interpretations in accounting for its stock option plans and accordingly, no compensation expense was recognized for Employee Stock Purchase Plan (ESPP) and stock options granted to employees in 2005. The Company recognized $361,000 of compensation expense for restricted stock awards according to APB No. 25 for the year ended December 31, 2005.

Effective January 1, 2006 the Company adopted the fair value recognition provisions of revised Statement of Financial Accounting Standards No. 123 (revised) (SFAS 123R), Share-Based Payment, which establishes accounting for share-based awards exchanged for employee services and requires companies to expense the estimated grant date fair value of these awards over the requisite employee service period. The Company elected the modified prospective method, which provides for certain changes to the method for valuing share-based compensation. Under the modified prospective method, prior periods are not revised for comparative purposes. The expense recognition provisions of SFAS 123R apply to new awards and to unvested awards that are outstanding on the effective date and subsequently modified or cancelled. Estimated compensation expense for awards outstanding at the effective date are being recognized over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under SFAS No. 123.

The Company’s loss before income taxes includes stock based compensation expense for the three and nine month periods ended September 30, 2006 of $710,000 and $2.3 million respectively, for the three and nine month period ended September 30, 2005 the Company had expensed $81,000.

On November 10, 2005, the FASB issued FASB Staff Position No. SFAS 123(R)-3, Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards. This guidance provides us with up to one year to determine which method to use when calculating our pool of tax benefit from stock based compensation. The Company is considering

9

its alternatives which include the method described in SFAS 123R or the simplified method to establish the beginning balance of the additional paid-in capital pool (APIC pool) related to the tax effects of employee share-based compensation, which is available to absorb tax deficiencies recognized subsequent to the adoption of SFAS 123R.

Pending Accounting Pronouncements

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 clarifies the accounting and reporting for income taxes recognized in accordance with SFAS No. 109, “Accounting for Income Taxes.” This Interpretation prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. The Company is currently evaluating the impact of FIN 48. The Company will adopt this Interpretation in the first quarter of 2007.

In August 2006, the Securities and Exchange Commission (“SEC”) issued new requirements for “Executive Compensation and Related Person Disclosure”. This ruling amends the disclosure requirements of total compensation for the principal executive officer, the principal financial officer, and three other most highly paid officers. In addition, this ruling expands the compensation disclosures for directors and requires that all compensation to each director be disclosed in a separate summary compensation table with improved narrative disclosure supplementing the tabular presentation. The Company anticipates adopting this ruling in the Company’s 2006 Annual Report on Form 10-K. or Proxy if applicable. The adoption of this ruling will have no impact on the Company’s consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157 “Fair Value Measurements” (“SFAS 157”). SFAS 157 provides a new single authoritative definition of fair value and provides enhanced guidance for measuring the fair value of assets and liabilities and requires additional disclosures related to the extent to which companies measure assets and liabilities at fair value, the information used to measure fair value, and the effect of fair value measurements on earnings. SFAS 157 is effective for the Company as of January 1, 2008. The Company is currently assessing the impact, if any, of SFAS 157 on its consolidated financial statements.

In September 2006, the FASB issued SFAS No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”). SFAS 158 requires balance sheet recognition of the over funded or under funded status of pension and postretirement benefit plans. Under SFAS 158, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized as a component of accumulated other comprehensive income (loss) within stockholders’ equity, net of tax effects, until they are amortized as a component of net periodic benefit cost. In addition, the measurement date and the date at which plan assets and the benefit obligation are measured, are required to be the Company’s fiscal year end. SFAS 158 is effective for the Company as of December 31, 2007, except for the measurement date provisions, which are effective December 31, 2009. The plan reported on our financial statement is regulated by the Swiss Government and is equally funded by the employees and the Company. We are still in the process of evaluating the full impact of adoption of SFAS 158. However, as the plan is over funded, we do not expect to have a material negative impact on the Company’s consolidated financial statements.

In September 2006, the SEC released Staff Accounting Bulletin No. 108 “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 provides interpretative guidance on how public companies quantify financial statement misstatements. There have been two common approaches used to quantify such errors. Under an income statement approach, the “roll-over” method, the error is quantified as the amount by which the current year income statement is misstated. Alternatively, under a balance sheet approach, the “iron curtain” method, the error is quantified as the cumulative amount by which the current year balance sheet is misstated. In SAB 108, the SEC established an approach that requires quantification of financial statement misstatements based on the effects of the misstatements on each of the Company’s financial statements and the related financial statement disclosures. This model is commonly referred to as a “dual approach” because it requires quantification of errors under both the roll-over and iron curtain methods. SAB 108 is effective for the Company as of January 1, 2007. The adoption of SAB 108 is not expected to have a material impact on the Company’s consolidated financial statements.

Note 4 – Stock-Based Compensation

The Company has two share-based compensation plans in effect as of September 30, 2006, under which incentive stock options, non-qualified stock options, Employee Stock Purchase Plan (ESPP) and restricted stock awards have been granted to employees. Generally, stock options and restricted stock awards vest over periods of one to four years and have a maximum contractual period of ten years. The following is a summary of the equity incentive plans under which stock options have been granted;

• The 1995 Stock Option Plan under which, as amended, 3,340,000 shares of common stock were reserved for future grant.

• The Company’s 1999 Director Stock Option Plan, under which 75,000 shares were reserved for future grant, was adopted in 1999 and approved by the Company’s shareholders in January 2000.

• In December 1999, the Company granted 294,030 non-qualified options to the Company’s then new President and Chief Executive Officer, Mr. Eibl, outside of the Company’s other option plans.

• In April 2002, in conjunction with the purchase of shares of its I-Bus/Phoenix and Electronic Components Group subsidiaries not already owned, the Company issued options to purchase approximately 520,000 shares of Maxwell common stock in exchange for options to purchase subsidiary common stock. This issuance of stock options was outside of the Company’s option plans.

• In November 2002, options to purchase 853,461 shares of common stock with strike prices above $10 per share, previously held by senior management and certain outside directors, were voluntarily cancelled, in exchange for the future issuance (May 2003) of substitute stock options with a strike price equal to the then-prevailing market price of the common stock.

The compensation cost that has been charged against income for those plans for the three and nine month periods ended September 30, 2006, is $696,000 and $2.3 million, respectively and $81,000 for the same periods ended in 2005.

The information for the employee stock options and ESPP is presented for the modified prospective portion of these grants. This allows the Company to use the share-based compensation accounting outlined in SFAS 123R for options and ESPP shares granted after December 31, 2005.

Employee Stock Purchase Plan (ESPP)

In 2004, the Company established the 2004 ESPP. The aggregate number of shares of common stock, which may be purchased under this Plan shall not exceed five hundred thousand (500,000) shares of common stock of the Company. As of September 30, 2006 the Company has issued a total of 24,353 shares of common stock from the current ESPP. The Company issued zero and 8,301 shares of stock for ESPP for the three and nine months ended September 30, 2006 respectively.

The plan permits substantially all employees to purchase common stock through payroll deductions, at 85% of the lower of the trading price of the stock at the beginning or at the end of each six-month offering period commencing on January 1 and July 1, 2006. The number of shares purchased is based on participants’ contributions made during the offering period.

The fair value of the “look back” option of the ESPP is estimated based on the stock price on the first day of the offering period using the Black-Scholes valuation model. The following assumptions were used in the valuation model for the three months ended September 30, 2006: expected dividend of zero, expected volatility of 54%, average risk-free interest rate of 5.04%; option life of .5 years, which is based on actual life; and a forfeiture rate of 0% as the number of shares to be purchased is calculated based on employee contributions. The fair value of the ESPP shares to be granted during the three month period September 30, 2006 was calculated for a 15% discount on the stock price; and by using the Black-Scholes valuation model for a call and a put option attributes of our ESPP, which resulted in a total value of $6.06 per share. Total compensation expense recognized for the ESPP for the three and nine months ended September 30, 2006 was $29,000 and $61,000 respectively.

Employee Stock Options Plan

The Company’s 2005 Omnibus Equity Incentive Plan (the “Incentive Plan”), approved by the shareholders, provides for the grant of stock based awards, including incentive stock options, non-qualified stock options, stock appreciation rights, performance awards, restricted stock, and restricted stock unit awards. This Incentive Plan had an initial 750,000 shares reserved for issuance with additional shares added to the plan from shares forfeited from the 1995 plan which may increase the number of shares available to be granted.

The fair value of each option award granted after January 1, 2006 is estimated on the date of grant using the Black-Scholes valuation model with the following assumptions:

	Nine Months Ended September 30, 2006	Nine Months Ended September 30, 2005
Expected dividends	—	—
Expected volatility	54.7% - 62.7%	57% - 61%
Average risk-free interest rate	4.4% - 5.0%	3.9% - 4.3%
Expected life (in years)	5.1 - 6.2	4.0

The dividend yield of zero is based on the fact that we have never paid cash dividends and have no present intention to pay cash dividends. Expected volatility is based on historical Company stock prices using a mathematical formula to measure the standard deviation of the change in the natural logarithm of our underlying stock price that is expected over a period of time, commensurate with the option life. This is expressed as an annual percentage rate required by our option-pricing model. For the nine month period September 30, 2006 and 2005 the weighted average volatility is 60.7% and 57%, respectively. The Company does not consider implied volatility due to the low volume of traded stock options. The risk-free interest rate is derived from the zero coupon rate for the option expected life. The expected life calculation is based on the Company’s history of exercised options from previous equity-based share option grants.

11

Share-based compensation expense recognized in the Consolidated Statement of Operations for fiscal 2006 is based on awards ultimately expected to vest. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on our historical experience of pre-vesting option forfeitures, we have assumed an 18.12% annualized forfeiture rate for the three month period ended September 30, 2006. The forfeiture rate had been estimated at 7.0% for the three month period ended March 31, 2006. The increase is based on an analysis of historical equity-based share option grants conducted by an independent third party. Under the true-up provisions of SFAS 123R, the Company recorded a recovery of prior expense of $73,000 because our current estimated forfeiture rate was higher than previously estimated. If the actual forfeiture rate is lower than estimated we will record an additional expense.

The following table summarizes the activity under the employee stock option plan:

	Employee Stock Options Number of Shares		Weighted Average Exercise Price		Weighted - Average Remaining Contractual Term	Aggregate Intrinsic Value ($000)
Outstanding January 1, 2006	2,493,633		$	8.62
Granted	187,075			15.04
Exercised	(489,041	)		8.31
Forfeited	(145,251	)		10.85
Expired	(1,501	)		11.06
Outstanding at September 30, 2006	2,044,915			9.11	5.69	$	23,139
Vested or expected to vest at September 30, 2006	1,947,599			8.89	5.34		22,488
Exercisable at September 30, 2006	1,622,498		$	8.14	4.92	$	19,967

The weighted-average grant date fair value of employee options granted during the three and nine month periods ended September 30, 2006 was $10.04 and $8.86 per share, respectively while the weighted-average grant date fair value for the three and nine month periods ended September 30, 2005 was $6.36 and $6.17 per share, respectively. The total intrinsic value of options exercised during the three and nine month periods ended September 30, 2006 was $410,000 and $3.8 million respectively while the total intrinsic value for the three and nine month periods ended September 30, 2005 was $408,000 and $674,000 respectively.

As of September 30, 2006 there was $2.1 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the employee option plan. The cost is expected to be recognized over a weighted average period of 2.03 years. Compensation cost for employee options recognized in the three and nine month periods ended September 30, 2006 was $260,000 and $794,000 respectively. Cash received from options exercised under all share-based payment arrangements for the nine month period ended September 30, 2006 was $4.2 million.

Restricted Stock Awards

Beginning in 2005 the Company awarded Directors and selected senior management restricted stock awards under the Company’s 2005 Omnibus Equity Incentive Plan. Vesting of restricted stock awards is contingent upon meeting various departmental, Company, market or performance conditions and requires a one year service period. The restricted stock awards have a contractual life, which is ten years. The number of shares available for issuance as restricted stock awards and employee stock options combined was an initial 750,000 shares with additional shares added from forfeitures from the 1995 Stock Option Plan.

The fair value of each restricted stock award is calculated on the date of grant using the stock price on the date of grant. The fair value of awards with market conditions have been determined using a Monte Carlo calculation. Performance conditions have estimated achievement dates over which compensation expense is recognized. The requisite service period is the greater of the estimated achievement date or the minimum 12-month vesting period. This requisite service period is determined based on an analysis of all the terms and conditions of each grant. The Company uses the requisite service period that is most likely to occur including the likelihood that the restricted stock award will not be earned. The initial requisite service period may be adjusted for changes in the expected outcomes of the related service or performance conditions with such changes recognized prospectively over the remaining requisite service period.

Share-based compensation expense recognized in the Consolidated Statement of Operations is based on awards ultimately expected to vest. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on our historical experience of pre-vesting award cancellations, we have assumed an annualized forfeiture rate for restricted stock awards of 5.8%. Under the true-up provisions of SFAS 123R, if the actual forfeiture rate is higher than estimated, a recovery of prior expense is recorded and if the actual forfeiture rate is lower than estimated an additional expense is recorded. The Company’s forfeiture rate change was immaterial in the period ended September 30, 2006 and no adjustment was recorded.

12

For the year ended December 31, 2005 the Company had recognized $361,000 of compensation expense for restricted stock awards in accordance with APB No. 25. The Company was required to calculate the restricted stock award expense based on the market price of the Company’s stock at the end of each reporting period. Under SFAS 123R the Company determines the fair value at grant date and expenses that amount over the requisite service period. As prescribed under SFAS 123R the Company has reassessed each restricted stock award that was active and not earned as of January 1, 2006 and determined appropriate share-based expense treatment under SFAS 123R.

The following table summarizes the activity under the restricted stock plan:

Nonvested Shares	Shares		Weighted Average Grant Date Fair Value
Nonvested at January 1, 2006	197,500		$	9.72
Granted	127,003			15.32
Vested	(101,663	)		7.85
Forfeited	—			—
Nonvested at September 30, 2006	222,840		$	13.76

The total grant date fair value of restricted stock awards granted during the three and nine month periods ended September 30, 2006 was zero and $1.9 million, respectively. Awards vested during the three and nine months ended September 30, 2006 were 15,000 and 101,663, respectively. As of September 30, 2006 there was $1.6 million of total unrecognized compensation cost related to nonvested restricted stock awards granted under the plan. The cost is expected to be recognized over a weighted average period of 0.74 years.

Compensation cost for restricted stock awards, employee stock options, ESPP and non-employee stock compensation included in Cost of sales; Selling, general and administrative; and Research and development is:

	Three Months ended September 30, 2006		Nine Months ended September 30, 2006
Stock-Based Compensation Costs:
Cost of sales	$	65,000	$	172,000
Selling, general and administrative		606,000		1,997,000
Research and development		39,000		170,000
Total Stock-Based Compensation Costs	$	710,000	$	2,339,000

Outstanding / Unsettled Option Plans

The Company adopted the provisions of SFAS 123R on January 1, 2006, the first day of the Company’s fiscal year, using a modified prospective method, where compensation cost is recognized beginning with the date of adoption. SFAS 123R is applicable for new awards and to awards that are outstanding on the effective date and if prior awards are subsequently modified or cancelled.

13

Options granted under these stock option plans are for the purchase of common stock of the Company at not less than the stock’s fair market value at the date of grant. They generally vest in cumulative annual installments of 20–30 percent over a four year period with a contractual term of ten years, while the restricted stock awards vest one year from date of grant and if the requirements of the award are completed within a term of ten years. New shares of common stock will be issued to satisfy stock option exercises and restricted stock grants.

Pro Forma

SFAS 123R requires us to present pro forma information for the comparative period prior to the adoption as if employee stock compensation expense had been determined based on the fair value at the grant date in accordance with SFAS 123. The following table illustrates the effect on net income and earnings per share if we had applied the fair value recognition provisions of SFAS 123 to employee stock compensation expense in the prior-year periods (dollars in thousands, except per-share data).

	Three Months Ended September 30, 2005			Nine Months Ended September 30, 2005
Net loss as reported	$	(1,335	)	$	(5,174	)
Add : Stock-based compensation expense included in net loss – as reported		81			81

Note 6 – Discontinued Operations

As part of a sale of the Company’s defense contracting business in 2001, the Company retained certain leases and lease obligations. Although the lease expired in April 2006 we have a lease obligations balance of $40,000 as of September 30, 2006 for any potential final billings for the discontinued operations of the Company’s defense contracting business.

14

In September 2002, the Company decided to suspend the operations of its PurePulse Technologies, Inc. subsidiary. PurePulse had been designing and developing systems that generate extremely intense, broad-spectrum, pulsed light to purify water and inactivate viruses and other pathogens that contaminate vaccines and products sourced from human or animal tissues, such as plasma derivatives, transfusion blood components and biopharmaceuticals. During the three months ended June 30, 2006, preferred shareholders of PurePulse provided Maxwell with a release of liability in the process of completely shutting down the PurePulse discontinued operation. Accordingly, we reversed a reserve for potential liability to these preferred Shareholders of approximately $259,000. The Company has preserved its intellectual property and certain other technology assets for a possible future sale of such assets. The carrying value of the assets at December 31, 2005 and September 30, 2006 was zero.

Note 7 – Related Parties

We transacted business with one Company considered to be a related party. Montena SA, the former parent Company of Montena our wholly owned subsidiary Maxwell SA and a significant shareholder of Maxwell Technologies, Inc., was the lessor for the Company’s headquarters in Rossens, Switzerland. The amount of lease payments paid to Montena SA during the three months ended September 30, 2006 and 2005 were zero and $197,000, respectively and during the nine months ended September 30, 2006 and 2005 were zero and $604,000, respectively. In January 2006, Montena SA sold the building to an unrelated third party and all payments for the Rossens property lease have been made to that unrelated party in 2006.

Note 8 – Legal Proceedings

We have been named as a defendant in a suit filed on March 4, 2004 in the Superior Court of the State of California for the County of San Luis Obispo. This suit, Edmonds vs. I-Bus/Phoenix, Inc., was filed by the plaintiff on his behalf and alleges damages concerning the repurchase of I-Bus/Phoenix, Inc. shares. On September 12, 2006 a California jury ruled in favor of the plaintiff for the amount of $231,000. The Company has accrued a total expense of $290,000, including estimated interest expense, in discontinued operations.

On October 17, 2006, Maxwell filed a patent infringement lawsuit against Nesscap in the United States District Court for the Southern District of California alleging that Nesscap’s sales of its ultracapacitors in the United States violate Maxwell patent(s). Maxwell is seeking monetary damages and an injunction to stop Nesscap’s sales of infringing products.

Note 9 – Convertible Debentures

On December 20, 2005, the Company issued $25.0 million in aggregate principal amount of senior subordinated convertible debentures due and payable in quarterly installments from December 2007 through December 2009 (the “Debentures”) and warrants to purchase 394,737 shares of Maxwell common stock. The net proceeds of the issuance totaled approximately $23.7 million after direct placement costs of approximately $1.3 million. The Debentures are convertible into 1,315,790 shares of Maxwell’s common stock at any time at the option of the holder.

At the issuance date, the Debentures were convertible by the holder at any time into common shares at a price of $19.00 per share subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the conversion price of the Debenture. After eighteen months from the issue date, Maxwell may require that a specified amount of the principal of the Debentures be converted if certain conditions are satisfied for a period of 20 consecutive trading days.

The warrants issued in connection with the issuance of the Debentures had an exercise price of $19.00 at the issuance date, subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the then current exercise price. The warrants are exercisable at any time through December 20, 2010. No warrants had been exercised as of September 30, 2006.

Interest is due quarterly with the interest rate fixed to the Federal Funds Rate plus 1.125% per annum. All or a portion of the accrued and unpaid interest may be paid in shares of Maxwell’s common stock at the Company’s option. During the three month period ended June 30, 2006, 20,346 shares of common stock were issued in-lieu of cash to pay interest. Accrued interest of $402,000 was payable as of September 30, 2006.

Maxwell is accounting for the conversion option in the Debentures and the associated warrants as derivative liabilities in accordance with SFAS 133, Accounting for Derivative Instruments and Hedging Activities, EITF 00-19, Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company’s Own Stock and EITF No. 05-2, The Meaning of “Conventional Convertible Debt Instrument” in Issue No. 00-19. The discount attributable to the issuance date aggregate fair value of the conversion options, warrants and issuance costs totaling $9.2 million, is being amortized using the effective interest method over the term of the Debentures. For the three and nine month periods ended September 30, 2006, $904,000 and $2.7 million respectively, of the discount and prepaid fees was amortized and included in the Condensed Consolidated Statement of Operations.

15

The change in fair value on revaluation of debenture conversion rights and warrant liabilities represents the difference between the fair value of the warrants and debenture conversion features at June 30, 2006 and their fair value on September 30, 2006, using the Black-Scholes pricing model. The effect of the fair market value adjustment for the holder’s and Maxwell’s conversion rights and the warrants for the three and nine month periods ended September 30, 2006 was a $50,000 gain, and $3.05 million loss, respectively, which is recorded as “Gain (Loss) on embedded derivatives and warrants.” The fair value of the holder’s and Maxwell’s conversion rights at September 30, 2006 were $7.6 million which is included in “Convertible debentures and long-term debt” on the balance sheet. The fair value of the warrants at September 30, 2006 was $3.9 million and is included in “Stock warrants” on the balance sheet.

In the event of any default or fundamental change as defined in the Debentures, the holder will be entitled to require Maxwell to redeem the Debentures (or any portion thereof) at a price equal to the greater of (i) the applicable redemption premium (ranging from 103%-115%) and (ii) the product of (x) the number of shares into which the Debenture is convertible using the $19.00 per share conversion price and (y) the closing price of Maxwell’s common stock on the day preceding the default or fundamental change.

As long as Debentures are outstanding, the Company is required to maintain an $8.0 million cash balance. This amount is classified as restricted cash at September 30, 2006 and December 31, 2005.

Note 10 – Short-Term and Long-Term Borrowings

Short-term borrowings

Maxwell SA, our European subsidiary, has a 2.0 million Swiss Francs (approximately $1.6 million as of September 30, 2006) credit agreement with a Swiss bank. Borrowings under the credit agreement bear interest at 2.52% with repayment terms extending beyond one month from the date of funding. Borrowings under the credit agreement are unsecured and as of September 30, 2006 and December 31, 2005, the full amount of the credit line was drawn.

Maxwell SA has a 1.0 million Swiss Francs (approximately $800,000 as of September 30, 2006) overdraft credit agreement with a Swiss bank, which renews annually. Borrowings under the credit agreement bear interest at 6.0%. Borrowings under the credit agreement are unsecured. As of September 30, 2006, 950,000 Swiss Francs (approximately ($760,000 was drawn on the overdraft credit line. As of December 31, 2005, none of the overdraft credit line was drawn. This agreement requires our Swiss subsidiary to maintain a minimum equity amount of 5.0 million Swiss Francs. We were in compliance with this covenant as of September 30, 2006.

The Company had a $3.0 million credit line from a U.S. bank for working capital purposes, subject to a one-year repayment period. The line had not been used and management decided not to renew the line, which expired on January 31, 2006.

Long-term borrowings

Maxwell SA has a term loan with a maximum draw of 1.2 million Swiss Francs, (approximately $920,000 as of September 30, 2006), for financing specific capital equipment expenditures. Borrowings under the term loan are secured by the equipment being purchased. This credit agreement bears interest at the Swiss inter-bank borrowing rate plus 2.0%. The term loan can be borrowed in quarterly advances up to the maximum limit and repaid over one to five years. As of September 30, 2006, approximately $552,000 was outstanding. The weighted average interest rate on the funds borrowed at September 30, 2006 was 4.13%.

Maxwell, SA has a lease agreement for the acquisition of manufacturing equipment up to an amount of 1.5 million Swiss Francs (approximately $1.2 million as of September 30, 2006). Under this lease agreement borrowings are for a minimum purchase price of 250,000 Swiss Francs and the lease is secured by the equipment being purchased. The leasing fee is 2.22% of the acquisition price plus VAT and a residual value of .5% of the acquisition price. Equipment suppliers are paid directly by the bank with interest payable at a rate of 6.75% per annum until the entire purchased amount has been borrowed at which time the lending arrangement converts to a lease. As of September 30, 2006 $172,000 of this credit agreement had been paid to suppliers.

Note 11 – Defined Benefit Plan

We have a retirement plan for our Swiss subsidiary that is classified as a defined benefit pension plan. The pension benefit is based on compensation, length of service and credited investment earnings. The plan guarantees both a minimum rate of return as well as minimum annuity purchase rates. The Company’s funding policy with respect to the pension plan is to contribute the amount required by Swiss law, using the required percentage applied to the employee’s compensation. There is no offset provision based on the obligation level of the fund. In addition, the employee is required to contribute an identical amount to the pension plan. This plan has a measurement date of December 31. We adopted the provisions of SFAS No. 132R, Employers’ Disclosures about Pensions and Other Postretirement Benefits in December 2003. Components of the net periodic benefit cost were as follows (in thousands):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2006			2005			2006			2005
Service cost	$	54		$	78		$	160		$	186
Interest cost		78			132			231			316
Expected return on plan assets		(280	)		(327	)		(824	)		(699	)
Net gain amortization		(56	)		(1	)		(167	)		(2	)
Net periodic benefit	$	(204	)	$	(118	)	$	(600	)	$	(199	)

Employer contributions of $92,000 and $69,000 were paid during the three month periods ended September 30, 2006 and 2005 respectively. Total employer contributions paid during the nine months ended September 30, 2006 and 2005 were $256,000 and $212,000, respectively. Additional employer contributions of approximately $16,000 are expected to be paid during the remainder of fiscal 2006.

Note 12 – Contingencies

The Defense Department’s auditing agency is auditing a contract entered into by our Microelectronics group as a subcontractor in 1995 and completed in 1999. The Company has requested a release of liability from the prime contractor. There is no assurance that such a release will be obtained or that the Company will not incur some liability. While management does not anticipate an unfavorable settlement of these matters, unfavorable results of the audit would result in an adverse impact on the Company’s cash flow and statement of operations.

The Company enters into indemnification agreements in the ordinary course of business in which the indemnified party is held harmless and is reimbursed for losses incurred from claims by third parties. In connection with divestitures of certain assets or businesses, the Company often provides indemnities to the buyer with respect to certain matters including, for example, environmental liabilities and unidentified liabilities related to periods prior to the disposition. Due to the uncertain nature of the indemnities, the maximum liability cannot be quantified. Liabilities for obligations are recorded where appropriate and when they are probable and can be reasonably estimated. Historically, the Company has not made significant payments for these obligations.

In 2005, a customer brought to our attention a possible defect in a product that we source from another manufacturer and resell to the customer. We are in the process of investigating this matter, but are not yet able to determine what, if any, warranty exposure Maxwell may have, and therefore, we have not recorded any warranty reserve provision.

In March 2006, a customer sent us a demand letter requesting payment of $535,000 for a tester product initially sold in 2002. The Company believes the request has no merit and no accrual has been made in the financial statements. We have communicated our position to the customer. As of the date of this filing there has been no resolution.

During the nine month period ended September 30, 2006, we used $14.1 million of cash in operating activities, compared with $5.0 million of cash used in operating activities during the same period in 2005. The increase in the cash used in operating activities is a result of higher inventory and accounts receivable balances supporting higher revenue levels primarily for the Boostcap product line as well as additional inventory for current and future customer orders in our Microelectronic product line. As revenue levels increase, additional cash will be required for working capital purposes.

The Company believes that the liquidity provided by existing cash, cash equivalents, investments in marketable securities, and borrowing available under our lines of credit, will provide sufficient capital to fund our capital equipment and working capital requirements and potential operating losses for more than the next 12 months if we are able to negotiate elimination of the current restriction on $8 million of cash. We are exploring other options, including a bridge financing and/or a private placement or public offering of marketable securities to provide additional liquidity.

Overview

Maxwell Technologies, Inc. is a Delaware corporation originally incorporated in 1965 under the name “Maxwell Laboratories, Inc.” In 1996, we changed our name to Maxwell Technologies, Inc. We are headquartered in San Diego, California. We develop, manufacture and market highly reliable, cost-effective energy storage and power delivery components and systems. Our products are designed and manufactured to provide failure-free, very low maintenance, performance over the life of the applications into which they are integrated. We believe that by satisfying the stringent requirements of such high-reliability, high-value applications, our products will be able to command much higher profit margins than commodity products. We operate as a single operating segment, High Reliability, which is comprised of two manufacturing locations and three product lines:

• Ultracapacitors: Our primary focus, ultracapacitors, are energy storage devices that possess a unique combination of high power density, extremely long operational life and the ability to charge and discharge very rapidly. Our BOOSTCAP^® ultracapacitor cells and multi-cell packs and modules provide highly reliable energy storage and power delivery solutions for applications in multiple industries, including transportation, energy, consumer and industrial electronics and telecommunications.

• High-Voltage Capacitors: Our CONDIS^® high-voltage capacitors are extremely robust devices that are designed and manufactured to perform reliably for decades in all climates. These products include grading and coupling capacitors and capacitive voltage dividers that are used to ensure the safety and reliability of electric utility infrastructure and other applications involving transport, distribution and measurement of high-voltage electrical energy.

• Radiation-Mitigated Microelectronic Products: Our radiation-mitigated microelectronic products include high-performance, high-density power modules, memory modules and single board computers that incorporate our proprietary RADPAK^® packaging and shielding technology and novel architectures that enable them to withstand environmental radiation effects and perform reliably in space.

Highlights of the Quarter Ended September 30, 2006

We reported revenue of $14.0 million and a net loss for the three-month period ended September 30, 2006 of approximately $5.4 million, or $0.31 loss per diluted share, versus revenue of $12.0 million and a net loss of $1.3 million, or $0.08 loss per diluted share, for the three month period ended September 30, 2005.

During the three and nine month period September 30, 2006, we continued to focus on developing strategic alliances, introducing new products, reducing product costs, increasing revenue, and production capacity and building and defending our intellectual property portfolio. Some of these efforts are described below:

• In January 2006, General Hydrogen Corporation placed a 200,000 unit, three-year, purchase order for BOOSTCAP^® ultracapacitors to enhance performance and energy management in its Hydricity^® Pack technology with strategic pricing if volume thresholds specified in the purchase order are met.

• In February 2006, Enercon GmbH, one of the world’s leading producers of wind energy systems, designated Maxwell as a preferred supplier, and placed a 1.5 million-unit purchase order for ultracapacitors for wind turbine blade pitch systems.

• In February 2006, Maxwell announced that it would introduce more than 30 BOOSTCAP^® ultracapacitor products over the next several months as part of a unique product family strategy featuring new “Power” and “Energy” product types to better meet the diverse requirements of the automotive, transportation, industrial and consumer electronics markets. At September 30, 2006 all 30 products had been introduced.

• In March 2006, Maxwell entered into an agreement to supply its latest generation of proprietary carbon powder-based ultracapacitor electrode material to Yeong-Long Technologies Co., Ltd. (YEC), for YEC’s new line of small cell ultracapacitor products, and to assist YEC in setting up worldwide marketing and distribution.

• In April 2006, Maxwell formed a toll manufacturing alliance with Belton Technology Group, a major Chinese manufacturer of precision components, flex circuits, circuit boards and other products, to support Maxwell’s forecasted growth for its BOOSTCAP^® ultracapacitors and multi-cell modules, driven by automotive, transportation and industrial electronics applications that are advancing toward high-volume production.

• In April 2006, Maxwell signed a contract with Shanghai Urban Electric Power Investment Development Corporation (SUEP), granting SUEP a license to manufacture and market ultracapacitor products based on Maxwell’s proprietary large cell and multi-cell module technology under its own brand in Mainland China. The contract, which also obligates SUEP to source ultracapacitor electrode material exclusively from Maxwell, has a six-year term, renewable by mutual agreement.

19

• In May 2006, Maxwell announced that it had introduced Energy and Power-type C cell ultracapacitor cells and multi-cell packs. The new 2.5-volt cells have the same external dimensions but weigh just one-third as much as the familiar C-size battery, and are designed for easy mounting on printed circuit boards and in other electrical devices and systems.

• In June 2006, Maxwell announced it had signed supply agreements with seven new distribution partners, strengthening and expanding the Company’s growing international channel network. Channel partners supply Maxwell’s BOOSTCAP^® ultracapacitor products and provide support services to the Company’s rapidly growing customer base in the transportation, automotive, telecommunications, and industrial and consumer electronics markets.

• In June 2006, Maxwell announced a new “Quick-Turn” BOOSTCAP^® ultracapacitor module program that offers shipment within 14 days of receipt of customer purchase orders for custom-configured multi-cell energy storage and power delivery solutions for systems requiring up to 540 volts. The Quick-Turn program leverages standard modular building blocks and proprietary balancing, monitoring and thermal transfer technologies to establish a new industry standard for flexibility and responsiveness to customer requirements.

• In August 2006, Maxwell announced it had signed a memorandum of understanding to collaborate on the development of a cold start system for the commercial transportation market. The collaboration is with Alcoa AFL Automotive a Tier 1 supplier to the automotive and commercial vehicle industries. The cold start system will incorporate Maxwell’s BOOSTCAP^® ultracapacitors with AFL’s power management system to develop an efficient engine starting system.

• In September 2006, Maxwell announced it had signed a memorandum of understanding with Kromberg & Schubert GmbH & Co. KG to incorporate Maxwell’s BOOSTCAP^® ultracapacitors into a highly efficient, low-cost, engine starting system for automobiles.

Results of Operations and Financial Condition —Quarter Ended September 30, 2006 Compared with Quarter Ended September 30, 2005

Total Revenue

Total revenue for the three months ended September 30, 2006 was approximately $14.0 million versus $12.0 million for the three months ended September 30, 2005. Two product lines experienced higher revenue levels in 2006 compared with the same period in 2005. High Voltage revenue increased approximately 5%, our Boostcap revenue increased approximately 73% while Microelectronics revenue was lower approximately 22% than the comparable period in 2005. Boostcap revenue grew due primarily to higher sales in Europe and due to a license fee of $494,000 recognized in the three month period ended September 30, 2006. We expect to recognize additional licensing fee revenue for our Boostcap product line in the last quarter of 2006 and first quarter of 2007.

Microelectronics revenue was negatively impacted due to delayed funding of one government contract. The U.S government approves their budget during the fourth quarter and we are dependent upon their approval of funding to continue recognizing revenue. This delay had a negative impact on revenue for the third quarter of 2006 from government funding limitations. We anticipate the funding limitations will be resolved in the fourth quarter of 2006 at which time we will recognize the revenue for work we have performed in the second, third, and fourth quarters.

Gross Profit

For the three month periods ended September 30, 2006 and 2005, gross profit was approximately $2.7 million and $3.5 million respectively, which represented 20% and 29% of revenue, respectively. The gross profit within the Boostcap product line for the three month period ended September 30, 2006 decreased because of increased production costs associated with our ramp up and phase in of increased manufacturing capacity. The challenge continues to be the ability to ramp up production and keep pace with demand while simultaneously achieving anticipated production efficiencies. Once these efficiencies are fully in place we anticipate achieving the required cost reductions to meet our pricing strategy. We expect to continue driving down production costs to meet the pricing requirements of the markets in which we compete.

Although our overall gross profit was lower for the three months ended September 30, 2006, there was an improvement in the gross profit of our High Voltage products compared with the same period in 2005. High Voltage gross profit improvements were primarily a result of reduced manufacturing costs and increased volume.

For the three month period ended September 30, 2006 costs of sales also included $65,000 of stock compensation expense related to our adoption of SFAS 123R versus the comparable period where there was no expense for stock compensation.

20

Selling, General & Administrative (SG&A) Expense

Selling, general and administrative (SG&A) expenses were approximately $4.3 million for the three month period ended September 30, 2006, compared with $3.1 million for the three month period ended September 30, 2005. As a percentage of revenues, SG&A expenses increased to 30% for the three month period ended September 30, 2006 from 26% for the three month period ended September 30, 2005. The approximate $1.2 million increase is predominantly related to stock compensation expense for restricted stock and stock option awards of $606,000 recognized in 2006 related to our adoption of SFAS 123R, compared with $81,000 for the same period in 2005. Additionally, sales expense, including labor and labor related expenses, outside commissions and advertising, increased to support significantly increased Boostcap revenue.

Research & Development (R&D) Expense

Research and development (R&D) expenses were approximately $2.4 million for the three month period ended September 30, 2006 compared with approximately $1.8 million for the same period in 2005. As a percentage of revenue, R&D expense was 17% and 15% for the three month periods ended September 30, 2006 and 2005, respectively. R&D expense for the three month period ended September 30, 2006 includes approximately $39,000 of stock compensation expense related to our adoption of SFAS 123R. Additionally, R&D spending, including labor and labor related expenses, engineering development and design consulting, increased to support Boostcap product development and Microelectronics single board computer product development.

Provision for Income Taxes

We recorded an income tax provision of $13,000 for the three month period ended September 30, 2006 compared with a provision for income tax of $197,000 for the three month period ended September 30, 2005. The tax provisions are a result of our Swiss subsidiary’s operating results.

The Company is currently evaluating its options with regard to establishing the beginning additional paid-in capital (APIC) pool of tax benefits related to the adoption of FAS123R. The short-cut method as described in FAS123R-3 is likely to be the method we adopt to establish our beginning APIC pool. We have until the fourth quarter of 2006 to establish the methodology to determine the APIC pool, which will be utilized against future tax expense related to stock option compensation.

Unremitted earnings of foreign subsidiaries have been included in the consolidated financial statements without giving effect to the United States taxes that may be payable on distribution to the United States because it is not anticipated such earnings will be remitted to the United States. If remitted, the additional United States taxes paid would not be material.

Discontinued Operations

In March 2001, we sold our Government Systems business for $20.7 million and recorded a gain of $1.1 million, net of a $2.7 million provision mainly related to ongoing lease obligations. As of September 30, 2006 a reserve provision of $40,000 remains for final lease close-out obligations. The lease expired in April 2006.

In March, 2004 our discontinued operation of I-Bus/Phoenix was named as a defendant in a lawsuit filed that alleged damages concerning the repurchase of I-Bus/Phoenix, Inc. shares. On September 12, 2006 a California jury ruled in the favor of the plaintiff for the amount of $231,000. The Company has accrued a total expense of $290,000, including accrued interest, in discontinued operations.

Nine month period September 30, 2006 Compared with Nine Month Period Ended September 30, 2005

Total Revenue

Total revenue for the nine months ended September 30, 2006 was approximately $38.7 million versus $32.8 million for the nine months ended September 30, 2005. Two product lines experienced higher revenue levels in 2006 compared with the same period in 2005. High Voltage revenue increased approximately 23% and Boostcap revenue increased approximately 47% while Microelectronics revenue was lower (approximately 15%) than the comparable period in 2005. High Voltage revenue grew in part due to strong demand in Asia. Boostcap revenue grew due primarily to higher sales in Europe and due to a license fee of $1.1 million recognized in the nine month period ended September 30, 2006.

Microelectronics revenue was negatively impacted due to delays in revenue for one government contract. The U.S. government approves their budget during the fourth quarter and we are dependent upon their approval of funding to continue to recognize revenue. We anticipate the funding limitation will be resolved in the fourth quarter of 2006 at which time we will recognize the revenue for work we have performed in the second, third, and fourth quarters.

21

Gross Profit

For the nine month periods ended September 30, 2006 and 2005, gross profit was approximately $8.6 million and $9.4 million respectively, which represented 22% and 29% of revenue, respectively. The gross profit within the Boostcap product line for the nine month period ended September 30, 2006 decreased because of increased production costs associated with our ramp up and phase in of increased manufacturing capacity. The challenge continues to be the ability to ramp up production and keep pace with demand while simultaneously achieving anticipated production efficiencies. Once these efficiencies are fully in place we anticipate achieving the required cost reductions to meet our pricing strategy. Second, and to a lesser extent, gross margins were lower due to higher than expected post product sales support and service costs for certain new and existing products.

Although our overall gross profit was lower for the nine months ended September 30, 2006, there was an improvement in the gross profit of our High Voltage products compared with the same period in 2005. High Voltage gross profit improvements were primarily a result of reduced manufacturing costs and increased volume.

For the nine month period ended September 30, 2006 costs of sales also included $172,000 of stock compensation expense related to our adoption of SFAS 123R versus none in the comparable period in 2005.

Selling, General & Administrative (SG&A) Expense

Selling, general and administrative (SG&A) expenses were approximately $12.4 million for the nine month period ended September 30, 2006, compared with $9.6 million for the nine month period ended September 30, 2005. As a percentage of revenues, SG&A expenses increased to 32% for the nine month period ended September 30, 2006 from 29% for the nine month period ended September 30, 2005. The approximate $2.8 million increase is primarily related to stock compensation expense for restricted stock and stock option awards of $2.0 million recognized in 2006 related to our adoption of SFAS 123R. Additionally, sales expense, including labor and labor related expenses, outside commissions and advertising, increased to support significantly increased Boostcap revenue.

Research & Development (R&D) Expense

Research and development (R&D) expenses were approximately $7.0 million for the nine month period ended September 30, 2006 compared with approximately $5.3 million for the same period in 2005. As a percentage of revenue, R&D expense was 18% and 16% for the nine month periods ended September 30, 2006 and 2005, respectively. R&D expense for the nine month period ended September 30, 2006 includes approximately $170,000 of stock compensation expense related to our adoption of SFAS 123R. Additionally, R&D spending, including labor and labor related expenses, engineering development and design consulting, increased to support Boostcap product development and Microelectronics single board computer product development.

Provision for Income Taxes

We recorded an income tax provision of $177,000 for the nine month period ended September 30, 2006 compared with a tax benefit of $8,000 for the nine month period ended September 30, 2005. The tax provisions are a result of our Swiss subsidiary operating results.

Unremitted earnings of foreign subsidiaries have been included in the consolidated financial statements without giving effect to the United States taxes that may be payable on distribution to the United States because it is not anticipated such earnings will be remitted to the United States. If remitted, the additional United States taxes paid would not be material.

Liquidity and Capital Resources

Changes in Cash Flow

During the nine month period ended September 30, 2006, we used $14.1 million of cash in operating activities, compared with $5.0 million of cash used in operating activities during the same period in 2005. The increase in the cash used in operating activities is a result of higher inventory and accounts receivable balances supporting higher revenue levels primarily for the Boostcap product line as well as additional inventory for current and future customer orders in our Microelectronic product line. As revenue levels increase, additional cash will be required for working capital purposes.

22

Investments in marketable securities increased to approximately $7.8 million at September 30, 2006 from approximately $696,000 at December 31, 2005 due to the Company investing proceeds from the convertible debentures issued at the end of 2005. Purchases of property, plant and equipment for $4.6 million during the nine month period ended September 30, 2006 were related to increasing factory capacity for Boostcap and High Voltage product lines. We expect our total capital expenditures for 2006 to be approximately $7.0 million which will be focused on increasing factory capacity at both of our manufacturing sites.

The primary financing activity was proceeds from the issuance of stock of $4.2 million during the nine month period ended September 30, 2006, which were a result of employees and former employees exercising stock options. Future stock option exercise activity cannot be predicted with any certainty.

Liquidity

As of September 30, 2006, we had approximately $12.9 million in cash, cash equivalents and restricted cash and approximately $7.8 million in short-term investments. We have a line of credit for 2 million Swiss Francs (approximately $1.6 million) from a Swiss bank for working capital in Switzerland. The line was fully used as of September 30, 2006. We also have a 1.2 million Swiss Francs (approximately $920,000) term loan available from a Swiss bank for capital equipment purchases. Approximately $552,000 of that facility was outstanding as of September 30, 2006. We have a 1 million Swiss Francs (approximately $800,000) line of credit with another Swiss bank for working capital, 950,000 Swiss Francs (approximately $760,000) of which was utilized as of September 30, 2006. We entered into a lease agreement in May 2006 for the acquisition of manufacturing equipment up to a maximum of 1.5 million Swiss Francs (approximately $1.2 million). The lease term is 48 months and $172,000 of the credit agreement had been used to purchase equipment under this agreement as of September 30, 2006. A $3.0 million line of credit from a U.S. bank, which was secured in 2004 and renewed in 2005, was not used and we decided to not to renew it in January, 2006.

We raised approximately $5.4 million, net of issuance expenses, from a private placement of common stock in July 2005. We raised approximately $23.7 million, net of issuance expenses, from the sale of convertible debentures in December 2005. Warrants issued as part of that convertible debt placement would provide and additional $7.5 million of cash if fully exercised. We believe that the liquidity provided by existing cash, cash equivalents, investments in marketable securities, and borrowing available under our lines of credit, will provide sufficient capital to fund our capital equipment and working capital requirements and potential operating losses for more than the next 12 months if we are able to negotiate elimination of the current restriction on $8 million of cash. We are exploring other options, including a bridge financing and/or a private placement or public offering of marketable securities to provide additional liquidity.

Debentures, Short Term and Long Term Borrowings

Convertible Debentures

On December 20, 2005, the Company issued $25 million in aggregate principal amount of senior subordinated convertible debentures due and payable in quarterly installments from December 2007 through December 2009 (the “Debentures”) and warrants to purchase 394,737 shares of Maxwell common stock. The net proceeds of the issuance totaled approximately $23.7 million after direct placement costs of approximately $1.3 million. The Debentures are convertible into 1.3 million shares of Maxwell’s common stock at any time at the option of the holder.

Interest is due quarterly with the interest rate fixed to the Federal Funds Rate plus 1.125% per annum. All or a portion of the accrued and unpaid interest may be paid in shares of Maxwell’s common stock at the Company’s option. At September 30, 2006 accrued interest of $402,000 was payable.

At the issuance date, the Debentures were convertible by the holder at any time into common shares at a price of $19.00 per share subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the conversion price of the Debenture. After eighteen months from the issue date, Maxwell may require that a specified amount of the principal of the Debentures be converted if certain conditions are satisfied for a period of 20 consecutive trading days.

The change in fair value on revaluation of debenture conversion rights and warrant liabilities represents the difference between the fair value of the warrants and debenture conversion features at their original issue date and their fair value on September 30, 2006 using a Black-Scholes calculation. The effect of the fair market value adjustment was a $50,000 gain in the three month period ended September 30, 2006, which is recorded as “Gain (loss) on embedded derivative liabilities.”

The fair value of the holder’s and Maxwell’s conversion rights at September 30, 2006 were $7.6 million, which is included in “Convertible debentures and long-term debt” on the balance sheet.

23

The warrants issued in connection with the issuance of the Debentures had an exercise price of $19.00 at the issuance date, subject to adjustment upon certain events such as the sale of equity securities by Maxwell at a price below the then current exercise price. The warrants are exercisable at any time through December 20, 2010. No warrants had been exercised as of September 30, 2006.

As long as Debentures are outstanding, the Company is required to maintain a cash balance of $8.0 million. This amount is classified as restricted cash at September 30, 2006 and December 31, 2005.

Short-term borrowings

Maxwell SA, our European subsidiary, has a 2.0 million Swiss Francs (approximately $1.6 million as of September 30, 2006) credit agreement with a Swiss bank. Borrowings under the credit agreement bear interest at 2.52% with repayment terms extending beyond one month from the date of funding. Borrowings under the credit agreement are unsecured and as of September 30, 2006 and 2005, the full amount of the credit line was drawn.

Maxwell SA has a 1.0 million Swiss Francs (approximately $800,000 as of September 30, 2006) overdraft credit agreement with a Swiss bank, which renews annually. Borrowings under the credit agreement bear interest at 6.0%. Borrowings under the credit agreement are unsecured. As of September 30, 2006, 950,000 Swiss Francs (approximately ($760,000) was drawn on the overdraft credit line. As of December 31, 2005, none of the overdraft credit line was drawn. This agreement requires our Swiss subsidiary to maintain a minimum equity amount of 5.0 million Swiss Francs. We were in compliance with this covenant as of September 30, 2006.

In January, 2006, a $3.0 million credit line from a U.S. bank expired. The line had never been drawn and management decided not to renew the line.

Long-term borrowings

Maxwell, SA has a term loan with a maximum draw of 1.2 million Swiss Francs, (approximately $920,000 as of September 30, 2006), for financing specific capital equipment expenditures. Borrowings under the term loan are secured by the equipment being purchased. This credit agreement bears interest at the Swiss inter-bank borrowing rate plus 2.0%. The term loan can be borrowed in quarterly advances up to the maximum limit and repaid over one to five years. As of September 30, 2006, approximately $552,000 was outstanding. The weighted average interest rate on the funds borrowed at September 30, 2006 was 4.13%.

Maxwell, SA has a lease agreement for the acquisition of manufacturing equipment up to an amount of 1.5 million Swiss Francs (approximately $1.2 million as of September 30, 2006). Under this lease agreement borrowings are for a minimum purchase of 250,000 Swiss Francs and the lease is secured by the equipment being purchased. The leasing fee is 2.22% of the acquisition price plus VAT and a residual value of .5% of the acquisition price. Equipment suppliers are paid directly by the bank with interest payable at a rate of 6.75% per annum until the entire amount has been borrowed at which time the lending arrangement converts to a lease. As of September 30, 2006 $172,000 of this credit agreement had been paid to suppliers.

Critical Accounting Policies

Management’s discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America. In the preparation of these financial statements we use certain assumptions and judgments, which may involve a high degree of judgment and complexity, these assumptions and estimates significantly impact the reported amounts of assets and liabilities and the disclosure of contingencies as well as reported amounts of revenues and expenses. These critical accounting policies, under different conditions or using different assumptions or estimates could show materially different results on our financial condition and results of operations.

Our critical accounting policies are described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2005. During the nine month period September 30, 2006 there were no significant changes to these critical accounting policies, other than the accounting policy related to share-based compensation as discussed below.

24

Stock Compensation

The Company has two active share-based payment plans which include options to purchase our common stock by our employees and directors under our stock option plans. Eligible employees can also purchase shares of our common stock at 85% of the lower of the fair market value at the close of the day prior or the last day of each six-month offering period under our employee stock purchase plans (ESPP). The Company has also awarded Directors and senior management with restricted stock awards subject to certain market or performance conditions.

As of December 31, 2005 The Company had accounted for these share-based payment plans using the disclosure only provisions of Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148 Accounting for Stock Based Compensation—Transitions and Disclosure. In accordance with the provisions of SFAS No. 123, the Company applies Accounting Principles Board Opinion No. 25 and related interpretations in accounting for its stock option plans, and accordingly, no compensation expense has been recognized for stock options granted to employees and for the ESPP under SFAS No. 123. For the year ended December 31, 2005 the Company had recognized $361,000 of compensation expense for restricted stock awards according to APB No. 25. If the Company had elected to recognize compensation cost based on the fair value method prescribed by SFAS 123, the Company’s would have recognized $1.6 million as disclosed per the pro forma in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005.

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS 123R, which replaces SFAS No. 123 (“SFAS 123”), Accounting for Stock-Based Compensation and supersedes APB Opinion No. 25 (“APB 25”), Accounting for Stock Issued to Employees. The Company adopted the provisions of SFAS 123R on January 1, 2006, the first day of the Company’s fiscal year, using a modified prospective application, where compensation cost is recognized beginning with the effective date for new awards and to awards that are outstanding on the effective date and if awards are subsequently modified or cancelled. The change in accounting for the two active share-based payment plans requires the Company to determine a value of the awards at the grant date and expense that amount over the requisite service period. The resulting financial statement impact for the three and nine months ended September 30, 2006 was $710,000 and $2.3 million respectively, which includes $14,000 and $33,000, respectively, for non-employees. The change in accounting treatment creates a total compensation cost related to non-vested awards not yet recognized as of September 30, 2006 of $3.7 million with a weighted average period over which they are expected to be recognized of 1.02 years.

Pending Accounting Pronouncements

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 clarifies the accounting and reporting for income taxes recognized in accordance with SFAS No. 109, “Accounting for Income Taxes.” This Interpretation prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. The Company is currently evaluating the impact of FIN 48. The Company will adopt this Interpretation in the first quarter of 2007.

In August 2006, the Securities and Exchange Commission (“SEC”) issued new requirements for “Executive Compensation and Related Person Disclosure”. This ruling amends the disclosure requirements of total compensation for the principal executive officer, the principal financial officer, and three other most highly paid officers. In addition, this ruling expands the compensation disclosures for directors and requires that all compensation to each director be disclosed in a separate summary compensation table with improved narrative disclosure supplementing the tabular presentation. The Company anticipates adopting this ruling in the Company’s 2006 Annual Report on Form 10-K. or Proxy if applicable. The adoption of this ruling will have no impact on the Company’s consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157 “Fair Value Measurements” (“SFAS 157”). SFAS 157 provides a new single authoritative definition of fair value and provides enhanced guidance for measuring the fair value of assets and liabilities and requires additional disclosures related to the extent to which companies measure assets and liabilities at fair value, the information used to measure fair value, and the effect of fair value measurements on earnings. SFAS 157 is effective for the Company as of January 1, 2008. The Company is currently assessing the impact, if any, of SFAS 157 on its consolidated financial statements.

In September 2006, the FASB issued SFAS No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans – an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”). SFAS 158 requires balance sheet recognition of the over funded or under funded status of pension and postretirement benefit plans. Under SFAS 158, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized as a component of accumulated other comprehensive income (loss) within stockholders’ equity, net of tax effects, until they are amortized as a component of net periodic benefit cost. In addition, the measurement date and the date at which plan assets and the benefit obligation are

25

measured, are required to be the Company’s fiscal year end. SFAS 158 is effective for the Company as of December 31, 2007, except for the measurement date provisions, which are effective December 31, 2009. The plan reported on our financial statements is regulated by the Swiss Government and is equally funded by the employees and the Company. We are still in the process of evaluating the full impact of adoption of SFAS 158. However, as the plan is over funded, we do not expect to have a material negative impact on the Company’s consolidated financial statements.

In September 2006, the SEC released Staff Accounting Bulletin No. 108 “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 provides interpretative guidance on how public companies quantify financial statement misstatements. There have been two common approaches used to quantify such errors. Under an income statement approach, the “roll-over” method, the error is quantified as the amount by which the current year income statement is misstated. Alternatively, under a balance sheet approach, the “iron curtain” method, the error is quantified as the cumulative amount by which the current year balance sheet is misstated. In SAB 108, the SEC established an approach that requires quantification of financial statement misstatements based on the effects of the misstatements on each of the Company’s financial statements and the related financial statement disclosures. This model is commonly referred to as a “dual approach” because it requires quantification of errors under both the roll-over and iron curtain methods. SAB 108 is effective for the Company as of January 1, 2007. The adoption of SAB 108 is not expected to have a material impact on the Company’s consolidated financial statements.

Impact of Inflation

We believe that inflation has not had a material impact on our results of operations for the periods presented. However, there can be no assurance that future inflation would not have an adverse impact on our operating results and financial condition.

Off Balance Sheet Arrangements

None.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We face exposure to financial market risks, including adverse movements in foreign currency exchange rates and changes in interest rates. These exposures may change over time and could have a material adverse impact on our financial results. We have not entered into or invested in any instruments that are subject to market risk, except as follows:

Foreign Currency Risk

Our primary foreign currency exposure is related to our subsidiary in Switzerland. Maxwell SA has Euro and local currency (Swiss Francs) revenue and operating expenses as well as loans in Swiss Francs. Changes in these currency exchange rates impact the U.S. dollar amount of revenue, expenses and debt. We do not hedge our currency exposures.

Interest Rate Risk

At September 30, 2006, we had approximately $3.1 million term debt, of which approximately $540,000 million is classified as long-term debt. The carrying value of these borrowings approximates fair value due to the short maturity dates of these instruments. We also had $25 million of long-term debt for convertible debentures issued on December 20, 2005, of which $25.9 million is classified as long-term debt. We do not anticipate significant interest rate swings in the near future; however, the exchange loss or gain may significantly affect our balance sheet or statement of operations. A 10% increase in the interest rate on our debt would not have a material effect on our related interest expense.

We invest excess cash in debt instruments of the U.S. Government and its agencies, bank certificates of deposit; commercial paper, high-quality corporate issuers and money market accounts. The primary objective of our investment activities is to preserve principal while maximizing yields without significantly increasing risk. Current policies do not allow the use of interest rate derivative instruments to manage exposure to interest rate changes. As of September 30, 2006, third parties managed approximately $7.8 million of the investment portfolio under guidelines approved by the Company’s Board of Directors. The balance of our cash is invested in money market accounts with banks. A 10% change in the interest rate on our marketable securities would not have a material effect on our related interest income.

Item 4. Controls and Procedures

Under the direction of our Chief Executive Officer and Chief Financial Officer, we evaluated our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) and our Chief Executive Officer and Chief Financial Officer concluded that (i) our disclosure controls and procedures were

26

effective as of September 30, 2006, and (ii) no change in internal control over financial reporting occurred during the quarter ended September 30, 2006, that has materially affected, or is reasonably likely to materially affect, such internal control over financial reporting

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

The Company’s subsidiary I-Bus/Phoenix, Inc. was named as a defendant in a suit filed on March 4, 2004 in the Superior Court of the State of California for the County of San Luis Obispo. This suit, Edmonds vs. I-Bus/Phoenix, Inc., was filed by the plaintiff on his behalf and alleges damages concerning the repurchase of I-Bus/Phoenix, Inc. shares. On September 12, 2006 a California jury ruled in favor of the plaintiff for the amount of $231,000. The Company has accrued a total expense of $290,000, including estimated interest expense, in discontinued operations.

On October 17, 2006, Maxwell filed a patent infringement lawsuit against Nesscap in the United States District Court for the Southern District of California alleging that Nesscap’s sales of its ultracapacitors in the United States violate Maxwell patent(s). Maxwell is seeking monetary damages and an injunction to stop Nesscap’s sales of infringing products.

Item 1A. – Risk Factors

There have been no material changes, other than the items noted below, from the risk factors disclosed in Part I, Item 1A, of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005.

We may enter into agreements for government contracts and provide services before funding is approved or obtained.

We may provide services for projects that may not be funded prior to us providing goods or services. If funds are not approved we would not recognize the revenue even though we may incur the expenses. We provide these goods or services knowing that we may not receive compensation. If funding is not eventually obtained, any capitalized expenses or inventory that is unique to the specific customer would be expensed, which could adversely impact our consolidated financial position, results of operations and cash flows.

We face risks selling products internationally which are or may become regulated by the US Government.

Our radiation shielded products are being classified as International Traffic in Arms Regulations (ITAR) which subject them to the licensing jurisdiction of the Department of Sate in accordance with the International Traffic in Arms Regulations (22 CFR 120 through 130) and are designated a defense article under Category XV(e) of the United States Munitions List. This means that all international sales of our radiation shielded products require licensing which may have the following impact: a) approval of the license may or may not be granted, b) the time between the receipt of an order and shipment of product may be increased, and c) sales could be impacted due to a customers preference of using non-ITAR regulated products. Additionally, we may be subject to new regulations that have a potential to impact sales or our products that we sell internationally or domestically.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

During the three month period ended September 30, 2006 there were no sales of unregistered securities that have not been previously reported in Form 8-K, the Company did not purchase its own securities, the only sale of registered securities was from employees exercising stock options and granting shares for interest expense as previously noted.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Submission of Matters to a Vote of Security Holders

No matters were submitted to shareholders for the three month period ended September 30, 2006.

Item 5. Other Information

None.
