Notes to Condensed Consolidated Financial Statements (unaudited)

September 30, 2012

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

ZBB Energy Corporation (“ZBB,” “we,” “us,” “our” or the “Company”) develops and manufactures distributed energy storage solutions based upon the Company’s proprietary zinc bromide rechargeable electrical energy storage technology and proprietary power electronics systems. A developer and manufacturer of modular, scalable and environmentally friendly power systems (“ZBB EnerSystem”), ZBB was incorporated in Wisconsin in1998 and is headquartered in Wisconsin, USA with offices also located in Perth, Western Australia.

The Company provides advanced electrical power management platforms targeted at the growing global need for distributed renewable energy, energy efficiency, power quality, and grid modernization. The Company and its power electronics subsidiary, Tier Electronics LLC, have developed a portfolio of intelligent power management platforms that directly integrate multiple renewable and conventional onsite generation sources with rechargeable zinc bromide flow batteries and other storage technology. The Company also offers advanced systems to directly connect wind and solar equipment to the grid and systems that can form various levels of micro-grids. Tier Electronics LLC participates in the energy efficiency markets through its hybrid vehicle control systems, and power quality markets with its line of regulation solutions. Together, these platforms solve a wide range of electrical system challenges in global markets for utility, governmental, commercial, industrial and residential end customers.

The consolidated financial statements include the accounts of the Company and those of its wholly-owned subsidiaries: Tier Electronics LLC which operates manufacturing facilities in Menomonee Falls, Wisconsin; ZBB Energy Pty Ltd. (formerly known as ZBB Technologies, Ltd.) which has an advanced engineering and development facility in Perth, Australia; and its sixty percent owned subsidiary ZBB PowerSav Holdings Limited located in Hong Kong which was formed in connection with the Company’s investment in the China joint venture. A former wholly-owned subsidiary ZBB Technologies, Inc. was merged with and into ZBB on January 1, 2012.

Interim Financial Data

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for fair presentation of the results of operations have been included. Operating results for the three month period ended September 30, 2012 are not necessarily indicative of the results that might be expected for the year ending June 30, 2013.

The condensed consolidated balance sheet at June 30, 2012 has been derived from audited financial statements at that date, but does not include all of the information and disclosures required by GAAP. For a more complete discussion of accounting policies and certain other information, refer to the Company’s annual report filed on Form 10-K for the fiscal year ended June 30, 2012.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly and majority-owned subsidiaries and have been prepared in accordance with U.S. GAAP. All significant intercompany accounts and transactions have been eliminated upon consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less to be cash equivalents. The Company maintains its cash deposits in fully insured accounts at financial institutions predominately in the United States, Australia, and Hong Kong. The Company has not experienced any losses in such accounts.

Accounts Receivable

The Company records allowances for doubtful accounts based on customer-specific analysis and general matters such as current assessments of past due balances and economic conditions. The Company writes off accounts receivable against the allowance when they become uncollectible. Accounts receivable are stated net of an allowance for doubtful accounts of $0 and $80,000, as of September 30, 2012 and June 30, 2012.

Inventories

Inventories are stated at the lower of cost or market using the first-in, first-out (FIFO) or average cost methods. The carrying value of inventories is reviewed for obsolescence on at least a quarterly basis or more frequently if warranted due to changes in conditions. Market is determined on the basis of estimated net realizable values.

Property, Plant and Equipment

Land, building, equipment, computers and furniture and fixtures are recorded at cost. Maintenance, repairs and betterments are charged to expense as incurred. Depreciation is provided for all plant and equipment on a straight line basis over the estimated useful lives of the assets. The estimated useful lives used for each class of depreciable asset are:

	Estimated Useful Lives
Manufacturing equipment	3 - 7 years
Office equipment	3 - 7 years
Building and improvements	7 - 40 years

Investment in Investee Company

Investee companies that are not consolidated, but over which the Company exercises significant influence, are accounted for under the equity method of accounting. Whether or not the Company exercises significant influence with respect to an investee depends on an evaluation of several factors including, among others, representation on the investee company’s board of directors and ownership level, which is generally a 20% to 50% interest in the voting securities of the investee company. Under the equity method of accounting, an investee company’s accounts are not reported in the Company’s condensed consolidated balance sheets and condensed statements of operations; however, the Company’s share of the earnings or losses of the investee company is reflected in the caption ‘‘Equity in loss of investee company” in the condensed consolidated statements of operations. The Company’s carrying value in an equity method investee company is reported in the caption ‘‘Investment in investee company’’ in the Company’s condensed consolidated balance sheets.

When the Company’s carrying value in an equity method investee company is reduced to zero, no further losses are recorded in the Company’s consolidated financial statements unless the Company guaranteed obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.

Intangible Assets

Intangible assets generally result from business acquisitions. Assets acquired and liabilities assumed are recorded at their estimated fair values. Intangible assets consist of a non-compete agreement, license agreement, and trade secrets. Amortization is recorded for intangible assets with determinable lives. Intangible assets are amortized using the straight line method over the three year estimated useful lives of the respective assets.

Goodwill

Goodwill is recognized as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed. Goodwill is not amortized but reviewed for impairment annually as of June 30 or more frequently if events or changes in circumstances indicate that its carrying value may be impaired. These conditions could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

In September 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) to Accounting Standards Codification (“ASC”) Topic 350, “Intangibles — Goodwill and Other.” This ASU amends the guidance in ASC Topic 350-20 on testing for goodwill impairment. The revised guidance allows entities testing for goodwill impairment to have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. If the Company determines, on the basis of qualitative factors, that it is more likely than not that the fair value of the reporting unit is less than the carrying amount, the two-step impairment test is required. If we cannot determine on the basis of qualitative factors that goodwill is not impaired, the two-step impairment test is required.

The first step of the impairment test requires the comparing of a reporting unit’s fair value to its carrying value. If the carrying value is less than the fair value, no impairment exists and the second step is not performed. If the carrying value is higher than the fair value, there is an indication that impairment may exist and the second step must be performed to compute the amount of the impairment. In the second step, the impairment is computed by estimating the fair values of all recognized and unrecognized assets and liabilities of the reporting unit and comparing the implied fair value of reporting unit goodwill with the carrying amount of that unit’s goodwill. The Company determined fair value as evidenced by market capitalization, and concluded that there was no need for an impairment charge as of September 30, 2012 and June 30, 2012.

Impairment of Long-Lived Assets

In accordance with FASB ASC Topic 360, "Impairment or Disposal of Long-Lived Assets," the Company assesses potential impairments to its long-lived assets including property, plant and equipment and intangible assets when there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable.

If such an indication exists, the recoverable amount of the asset is compared to the asset’s carrying value. Any excess of the asset’s carrying value over its recoverable amount is expensed in the consolidated statement of operations. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate. Management has determined that there were no long-lived assets impaired as of September 30, 2012 and June 30, 2012.

Warranty Obligations

The Company typically warrants its products for twelve months after installation or eighteen months after date of shipment, whichever first occurs. Warranty costs are provided for estimated claims and charged to cost of product sales as revenue is recognized. Warranty obligations are also evaluated quarterly to determine a reasonable estimate for the replacement of potentially defective materials of all energy storage systems that have been shipped to customers.

While the Company actively engages in monitoring and improving its evolving battery and production technologies, there is only a limited product history and relatively short time frame available to test and evaluate the rate of product failure. Should actual product failure rates differ from the Company’s estimates, revisions will be made to the estimated rate of product failures and resulting changes to the liability for warranty obligations. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.

As of September 30, 2012 and June 30, 2012, included in the Company’s accrued expenses were $655,967 and $418,557, respectively, related to warranty obligations. Such amounts are included in accrued expenses in the accompanying condensed consolidated balance sheets.

The following is a summary of accrued warranty activity:

	Three Months and Year Ended
	September 30, 2012			June 30, 2012

Beginning balance	$	418,557		$	413,203
Accruals for warranties during the period		219,410			196,753
Settlements during the period		(27	)		(126,902	)
Adjustments relating to preexisting warranties		18,027			(64,497	)
Ending balance	$	655,967		$	418,557

Revenue Recognition

Revenues are recognized when persuasive evidence of a contractual arrangement exits, delivery has occurred or services have been rendered, the seller’s price to buyer is fixed and determinable, and collectability is reasonably assured. The portion of revenue related to installation and final acceptance, is deferred until such installation and final customer acceptance are completed.

For sales arrangements containing multiple elements (products or services), revenue relating to undelivered elements is deferred at the estimated fair value until delivery of the deferred elements. To be considered a separate element, the product or service in question must represent a separate unit under SEC Staff Accounting Bulletin 104, and fulfill the following criteria: the delivered item(s) has value to the customer on a standalone basis; there is objective and reliable evidence of the fair value of the undelivered item(s); and if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. If the arrangement does not meet all criteria above, the entire amount of the transaction is deferred until all elements are delivered. Revenue from time and materials based service arrangements is recognized as the service is performed.

The portion of revenue related to engineering and development is recognized ratably upon delivery of the goods or services pertaining to the underlying contractual arrangement or revenue is recognized as certain activities are performed by the Company over the estimated performance period.

The Company charges shipping and handling fees when products are shipped or delivered to a customer, and includes such amounts in net revenues. The Company reports its revenues net of estimated returns and allowances.

Revenues from government funded research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract. In many cases, the Company is reimbursed only a portion of the costs incurred or to be incurred on the contract. Government funded research and development contracts are generally multi-year, cost-reimbursement and/or cost-share type contracts. The Company is generally reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract.

Total revenues of $1,823,321 and $1,637,857 were recognized for the three months ended September 30, 2012 and September 30, 2011, respectively. Revenues for the three months ended September 30, 2012 were comprised of four significant customers (83% of total revenues) and revenues for the three months ended September 30, 2011 was one significant customer (85% of total revenues).

Engineering and Development Revenues

On April 8, 2011, the Company entered into a Collaboration Agreement (the “Collaboration Agreement”) with Honam Petrochemical Corporation (“Honam”), a division of LOTTE Petrochemical, pursuant to which the Company agreed with Honam to collaborate on the further technical development of the Company’s third generation zinc bromide flow battery module (the “Version 3 Battery Module”). Pursuant to the Collaboration Agreement, Honam was required to pay the Company a total of $3,000,000 as follows: (1) $1,000,000 within 10 days following the execution of the Collaboration Agreement (subsequently received on April 9, 2011); (2) $500,000 by June 30, 2011 (subsequently received on June 30, 2011); (3) $1,200,000 by October 10, 2011 (subsequently received on October 10, 2011) and (4) $300,000 within 10 days after a single Version 3 Battery Module test station is set up at Honam’s research and development center (subsequently received on March 30, 2012). The Company recognized $1,400,000 of revenue under this agreement during the three months end September 30, 2011 and the Company had recognized $3,000,000 as revenue as of June 30, 2012 based on performance milestones achieved. Pursuant to the Collaboration Agreement, the parties are required to negotiate a license agreement under which upon the completion of the collaboration project and the receipt by the Company of all payments due under the Collaboration Agreement, the Company shall grant to Honam: (1) a fully paid-up, exclusive and royalty-free license to sell and manufacture the Version 3 Battery Module in Korea and (2) non-exclusive rights to sell the Version 3 Battery Module in Japan, Thailand, Taiwan, Malaysia, Vietnam and Singapore. In connection with such non-exclusive rights, Honam is required to pay us a royalty.

On December 13, 2011, the Company entered into a joint development and license agreement with a global technology company to jointly develop flow batteries. The objective of the joint development agreement is to develop low cost, high energy density grid scale flow battery stacks and systems that could lead to a significant cost reduction for grid level storage. Under the terms of the joint development agreement, the Company received $175,000 in December 2011, and will receive payments of $75,000 every three months starting April 2012 through January 2013 (subsequently received $75,000 during April, June and October of 2012) and $100,000 every three months starting in April 2013 through January 2014. The global technology company also purchased 933,333 shares of the Company’s common stock in December 2011 for $700,000. The Company recognizes revenue under this agreement upon achievement of certain performance milestones. The Company recognized $200,000 of revenue under this agreement in the three months ended September 30, 2012.

Milestone payments under collaborative arrangements are triggered by the results of the Company’s engineering and development efforts. Milestones related to the Company’s development-based activities may include initiation of various phases of engineering and development activities, successful completion of a phase of development, or delivery of specified equipment or products. Due to the uncertainty involved in meeting these development-based milestones, the development-based milestones are considered to be substantial (i.e. not just achieved through passage of time) at the inception of the collaboration agreement. In addition, the amounts of the payments assigned thereto are considered to be commensurate with the enhancement of the value of the delivered intellectual property as a result of our performance. The Company’s involvement is necessary to the achievement of development-based milestones. The Company accounts for development-based milestones as revenue upon achievement of the substantive milestone events. In addition, upon the achievement of development-based milestone events, the Company has no future performance obligations related to any milestone payments.

Included in engineering and development revenues were $218,183 and $1,411,750 respectively, for the three months ended September 30, 2012 and September 30, 2011 related to the collaborative agreements. Engineering and development costs related to the collaboration agreements totaled $45,065 and $481,107 for the three months ended September 30, 2012 and September 30, 2011.

As of September 30, 2012 and June 30, 2012, the Company had no unbilled amounts from engineering and development contracts in process. The Company had received $1,980 and $129,950 in customer payments for engineering and development contracts, representing deposits in advance of performance of the contracted work, as of September 30, 2012 and June 30, 2012, respectively.

Advanced Engineering and Development Expenses

The Company expenses advanced engineering and development costs as incurred. These costs consist primarily of labor, overhead, and materials to build prototype units, materials for testing, development of manufacturing processes and include consulting fees and other costs.

To the extent these costs are separately identifiable, incurred and funded by advanced engineering and development type agreements with outside parties, they are shown separately on the consolidated statements of operations as a “cost of engineering and development.”

Stock-Based Compensation

The Company measures all “Share-Based Payments", including grants of stock options, restricted shares and restricted stock units, to be recognized in its consolidated statement of operations based on their fair values on the grant date, consistent with FASB ASC Topic 718, “Stock Compensation,” guidelines.

Accordingly, the Company measures share-based compensation cost for all share-based awards at the fair value on the grant date and recognition of share-based compensation over the service period for awards that are expected to vest. The fair value of stock options is determined based on the number of shares granted and the price of the shares at grant, and calculated based on the Black-Scholes valuation model.

The Company compensates its outside directors primarily with restricted stock units (“RSUs”) rather than cash. The grant date fair value of the restricted stock unit awards is determined using the closing stock price of the Company’s common stock on the day prior to the date of the grant, with the compensation expense recognized over the vesting period of restricted stock unit awards, net of estimated forfeitures.

The Company only recognizes expense to its condensed consolidated statements of operations for those options or shares that are expected ultimately to vest, using two attribution methods to record expense, the straight-line method for grants with only service-based vesting or the graded-vesting method, which considers each performance period, for all other awards. See Note 9.

Income Taxes

The Company records deferred income taxes in accordance with FASB ASC Topic 740, “Accounting for Income Taxes.” This ASC Topic requires recognition of deferred income tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted tax rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance when necessary to reduce deferred income tax assets to the amount expected to be realized. There were no net deferred income tax assets recorded as of September 30, 2012 and June 30, 2012.

The Company applies a more-likely-than-not recognition threshold for all tax uncertainties as required under FASB ASC Topic 740, which only allows the recognition of those tax benefits that have a greater than fifty percent likelihood of being sustained upon examination by the taxing authorities.

The Company’s U.S. Federal income tax returns for the years ended June 30, 2009 through June 30, 2012 and the Company’s Wisconsin and Australian income tax returns for the years ended June 30, 2008 through June 30, 2012 are subject to examination by taxing authorities.

Foreign Currency

The Company uses the United States dollar as its functional and reporting currency, while the Australian dollar and Hong Kong dollar are the functional currencies of its foreign subsidiaries. Assets and liabilities of the Company’s foreign subsidiaries are translated into United States dollars at exchange rates that are in effect at the balance sheet date while equity accounts are translated at historical exchange rates. Income and expense items are translated at average exchange rates which were applicable during the reporting period. Translation adjustments are accumulated in accumulated other comprehensive loss as a separate component of equity in the condensed consolidated balance sheets.

Loss per Share

The Company follows the FASB ASC Topic 260, “Earnings per Share,” provisions which require the reporting of both basic and diluted earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (net loss) per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. In accordance with the FASB ASC Topic 260, any anti-dilutive effects on net income (loss) per share are excluded. For the three months ended September 30, 2012 and September 30, 2011 there were 14,205,413 and 7,031,696 shares of common stock underlying options, restricted stock units and warrants that are excluded, respectively.

Concentrations of Credit Risk and Fair Value

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable.

The Company maintains significant cash deposits primarily with three financial institutions. All deposits are fully insured as of September 30, 2012. The Company has not previously experienced any losses on such deposits. Additionally, the Company performs periodic evaluations of the relative credit ratings of these institutions as part of its investment strategy.

Concentrations of credit risk with respect to accounts receivable are limited due to accelerated payment terms in current customer contracts and creditworthiness of the current customer base.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term nature of these instruments. The carrying value of bank loans and notes payable approximate fair value based on their terms which reflect market conditions existing as of September 30, 2012 and June 30, 2012.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions 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 amount of revenues and expenses during the reporting period. It is reasonably possible that the estimates we have made may change in the near future. Significant estimates underlying the accompanying consolidated financial statements include those related to:

●	the timing of revenue recognition;
●	the allowance for doubtful accounts;
●	provisions for excess and obsolete inventory;
●	the lives and recoverability of property, plant and equipment and other long-lived assets, including goodwill and other intangible assets;
●	contract costs and reserves;
●	warranty obligations;
●	income tax valuation allowances;
●	stock-based compensation;
●	fair values of assets acquired and liabilities assumed in a business combination; and
●	valuation of warrants

Reclassifications

Certain amounts previously reported have been reclassified to conform to the current presentation.

Segment Information

The Company has determined that it operates as one reportable segment.

Recent Accounting Pronouncements

In July 2012, the FASB amended its authoritative guidance related to testing indefinite-lived intangible assets for impairment. Under the revised guidance, entities testing their indefinite-lived intangible assets for impairment have the option of performing a qualitative assessment before performing further impairment testing. If entities determine, on a basis of qualitative factors, that it is more-likely-than-not that the asset is impaired, a quantitative test is required. The guidance becomes effective in the beginning of the Company’s fiscal 2014, with early adoption permitted. The Company is currently evaluating the timing of adopting this guidance which is not expected to have an impact on the Company’s consolidated financial statements.

In June 2011, the FASB issued new accounting guidance related to the presentation of comprehensive income (loss) that eliminates the current option to report other comprehensive income (loss) and its components in the statement of changes in equity. Under this guidance, an entity can elect to present items of net income (loss) and other comprehensive income (loss) in one continuous statement or two consecutive statements. This guidance was effective for our current reporting period.

NOTE 2– CHINA JOINT VENTURE

On August 30, 2011, the Company entered into agreements providing for establishment of a joint venture to develop, produce, sell, distribute and service advanced storage batteries and power electronics in China (the “Joint Venture”). Joint venture partners include PowerSav, Inc. (“PowerSav”), AnHui Xinlong Electrical Co. and Wuhu Huarui Power Transmission and Transformation Engineering Co. The Joint Venture was established upon receipt of certain governmental approvals from China which were received in November 2011.

The Joint Venture operates through a jointly-owned Chinese company located in Wuhu City, Anhui Province named Anhui Meineng Store Energy Co., Ltd. (“AHMN”). AHMN intends to initially assemble and ultimately manufacture the Company’s products for sale in the power management industry on an exclusive basis in mainland China and on a non-exclusive basis in Hong Kong and Taiwan.

In connection with the Joint Venture, on August 30, 2011 the Company and certain of its subsidiaries entered into the following agreements:

●	Joint Venture Agreement of Anhui Meineng Store Energy Co., Ltd. (the “China JV Agreement”) by and between ZBB PowerSav Holdings Limited, a Hong Kong limited liability company (“Holdco”), and Anhui Xinrui Investment Co., Ltd, a Chinese limited liability company; and
●	Limited Liability Company Agreement of ZBB PowerSav Holdings Limited by and between ZBB Cayman Corporation and PowerSav, Inc. (the “Holdco Agreement”).

In connection with the Joint Venture, upon establishment of AHMN, the Company and certain of its subsidiaries entered into the following agreements:

●	Management Services Agreement by and between AHMN and Holdco (the “Management Services Agreement”);
●	License Agreement by and between Holdco and AHMN (the “License Agreement”); and
●	Research and Development Agreement by and between the Company and AHMN (the “Research and Development Agreement”).

Pursuant to the China JV Agreement, AHMN was capitalized with approximately $13.6 million of equity capital. The Company’s only capital contributions to the Joint Venture were the contribution of technology to AHMN via the License Agreement and $200,000 in cash. The Company’s indirect interest in AHMN equals approximately 33%.

The Company’s investment in AHMN was made through Holdco, a holding company formed with PowerSav. Pursuant to the Holdco Agreement, the Company contributed to Holdco technology via a license agreement with an agreed upon value of approximately $4.1 million and $200,000 in cash in exchange for a 60% equity interest and PowerSav agreed to contribute to Holdco $3.3 million in cash in exchange for a 40% equity interest. The initial capital contributions (consisting of the Company’s technology contribution and one half of required cash contributions) were made in December 2011. The subsequent capital contributions (consisting of one half of the required cash contribution) were made on May 16, 2012. For financial reporting purposes, Holdco’s assets and liabilities are consolidated with those of the Company and PowerSav’s 40% interest in Holdco is included in the Company’s consolidated financial statements as a noncontrolling interest. For the three months ended September 30, 2012, AHMN had a net loss of $632,385.

The Company’s basis in the technology contributed to Holdco is $0 due to U.S. GAAP requirements related to research and development expenditures. The difference of approximately $4.1 million in the Company’s basis in this technology and the valuation of the technology by AHMN is accounted for by the Company through the elimination of the amortization expense recognized by AHMN related to the technology.

The Company has the right to appoint a majority of the members of the Board of Directors of Hong Kong Holdco and Hong Kong Holdco has the right to appoint a majority of the members of the Board of Directors of AHMN.

Pursuant to the Management Services Agreement Holdco will provide certain management services to AHMN in exchange for a management services fee equal to five percent of AHMN’s net sales for the first five years and three percent of AHMN’s net sales for the subsequent three years.

Pursuant to the License Agreement, Holdco granted to AHMN (1) an exclusive royalty-free license to manufacture and distribute the Company’s ZBB EnerStore, zinc bromide flow battery, version three (V3) (50KW) and ZBB EnerSection, power and energy control center (up to 250KW) (the “Products”) in mainland China in the power supply management industry and (2) a non-exclusive royalty-free license to manufacture and distribute the Products in Hong Kong and Taiwan in the power supply management industry.

Pursuant to the Research and Development Agreement, AHMN may request the Company to provide research and development services upon commercially reasonable terms and conditions. AHMN would pay the Company’s fully-loaded costs and expense incurred in providing such services.

The Company had product sales of $703,438 to AHMN during the three months ended September 30, 2012.

The operating results for AHMN for the period from July 1, 2012 to September 30, 2012 is summarized as follows:

	September 30, 2012

NOTE 3 - GOING CONCERN

The accompanying condensed consolidated financial statements have been prepared on the basis of a going concern which contemplates that the Company will be able to realize assets and discharge its liabilities in the normal course of business. Accordingly, they do not give effect to any adjustments that would be necessary should the Company be required to liquidate its assets. The Company incurred a net loss of $2,882,790 attributable to ZBB Energy Corporation for the three months ended September 30, 2012 and as of September 30, 2012 has an accumulated deficit of $71,936,699 and total ZBB Energy Corporation equity of $9,409,742. The ability of the Company to settle its total liabilities of $8,233,297 and to continue as a going concern is dependent upon closing additional sales orders and availability of future funding and achieving profitability. The accompanying condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

As described in detail in Notes 8 and 11, in the year ended June 30, 2012 the Company raised approximately $2.2 million in net proceeds through the issuance of Zero Coupon Convertible Subordinated Notes in May 2012 (subsequently repaid in full by June 30, 2012), approximately $2.2 million in net proceeds through the issuance of shares of Series A Preferred Stock pursuant to the Socius Agreement and approximately $15.5 million through the issuance of shares of common stock in various transactions to certain investors.

The Company believes that working capital sufficient to fund operations through June 30, 2013 is dependent upon closing additional sales orders and/or raising additional investment capital. However, there can be no assurances that unforeseen circumstances will not require the Company to raise additional investment capital to fund its operations. If the Company is unable to obtain additional required funding, the Company’s financial condition and results of operations may be materially adversely affected and the Company may not be able to continue operations. Accordingly, the Company is currently implementing certain plans designed to generate additional sales and reduce costs and is exploring various alternatives including strategic partnership transactions, and/or government programs that may be available to the Company.

NOTE 7 – GOODWILL

The Company acquired ZBB Technologies, Inc., a former wholly-owned subsidiary, through a series of transactions in March 1996. ZBB Technologies Inc. was subsequently merged with and into ZBB Energy Corporation on January 1, 2012. The goodwill amount of $1.134 million, the difference between the price paid for ZBB Technologies, Inc. and the net assets of the acquisition, amortized through fiscal 2002, resulted in the net goodwill amount of $803,079 as of September 30, 2012 and June 30, 2012.

The Company accounts for goodwill in accordance with FASB ASC Topic 350-20, “Intangibles - Goodwill and Other - Goodwill” under which goodwill and other intangible assets deemed to have indefinite lives are not amortized but are subject to annual impairment tests. The implied fair value of goodwill is the amount determined by deducting the estimated fair value of all tangible and identifiable intangible net assets of the reporting unit to which goodwill has been allocated from the estimated fair value of the reporting unit. If the recorded value of goodwill exceeds its implied value, an impairment charge is recorded for the excess.

NOTE 8 – BANK LOANS AND NOTES PAYABLE

In May 2012 the Company entered into Securities Purchase Agreements with certain investors providing for the sale of a total of $2,465,000 of Zero Coupon Convertible Subordinated Notes (the “Notes”). The Notes, which were to mature on August 31, 2012, were issued to investors with a principal amount equal to the investor’s subscription amount times 110% and did not bear interest except in the instance of default. The Notes were convertible into shares of common stock of the Company at an exercise price equal to $0.53, which was the closing price of the common stock on May 1, 2012 (the “Conversion Price”). In connection with the Notes, the Company entered into a security agreement with the lenders providing for a security interest in all of the assets of the Company and certain subsidiaries of the Company. In connection with the purchase of Notes, each investor received a five-year warrant to purchase a number of shares of Common Stock equal to 55% times such investor’s investment in the Notes divided by the Conversion Price at an exercise price equal to the Conversion Price. Certain directors and officers of the Company invested $330,000 in the Notes. The proceeds to the Company were $2,223,307. The Company recorded financing costs of approximately $227,693 in connection with the issuance of the Notes as interest expense during the year ended June 30, 2012. As of June 30, 2012 the Notes were either converted into the Company’s stock or paid in full. Interest expense related to the Notes was $1,366,450 for the year ended June 30, 2012.

NOTE 9 – EMPLOYEE/DIRECTOR EQUITY INCENTIVE PLANS

During the three months ended September 30, 2012 and September 30, 2011, the Company’s results of operations include compensation expense for stock options granted and restricted shares vested under its various equity incentive plans. The amount recognized in the financial statements related to stock-based compensation was $236,150 and $300,228, based on the amortized grant date fair value of options and vesting of restricted shares during the three months ended September 30, 2012 and September 30, 2011, respectively.

At the annual meeting of shareholders held on November 10, 2010, the Company’s shareholders approved the Company’s 2010 Omnibus Long-Term Incentive Plan (the “Omnibus Plan”). The Omnibus Plan authorizes the board of directors or a committee thereof, to grant the following types of equity awards under the Omnibus Plan: Incentive Stock Options (“ISOs”), Non-qualified Stock Options (“NSOs”), Stock Appreciation Rights (“SARs”), Restricted Stock, Restricted Stock Units (“RSUs”), cash- or stock-based Performance awards (as defined in the Omnibus Plan) and other stock-based awards. Four million shares of common stock are reserved for issuance under the Omnibus Plan. In connection with the adoption of the Omnibus Plan the Company’s Board of Directors froze the Company’s other stock option plans and no further grants may be made under those plans.

On November 10, 2010, (1) a total of 511,143 RSUs were granted to the Company’s directors in payment of directors fees through November 2011 pursuant to the Company’s Director Compensation Policy, (2) a total of 574,242 RSUs previously issued to the Company’s directors pursuant to this policy which provided for cash settlement were converted to stock settled RSUs, and (3) 115,000 RSUs were granted in total to a consultant and to the Company’s President and CEO. On November 9, 2011, an additional 548,051 RSUs were granted to the Company’s directors in payment of directors fees through November 2012. On May 6, 2011 the Company’s President and CEO was awarded 200,000 RSUs that vest ratably over a three year period. On March 23, 2012, the Company’s Compensation Committee of the Company’s Board of Directors awarded 500,000 RSUs to the Company’s President and CEO which vested based on the satisfaction of certain performance targets for the six-month period ending September 30, 2012. As of September 30, 2012, 450,000 shares had vested and the remaining shares were cancelled.

During the three months ended September 30, 2012 options to purchase 640,050 shares were granted to employees exercisable at prices from $0.35 to $0.38 and exercisable at various dates through September 2020.

During the three months ended September 30, 2012 options to purchase 640,050 shares were granted to employees exercisable at prices from $0.35 to $0.38 per share based on various service and performance based vesting terms from July 2012 through September 2015 and exercisable at various dates through September 2020. During the three months ended September 30, 2011 options to purchase 543,000 shares were granted to employees exercisable at prices from $0.59 to $1.16 per share based on various service and performance based vesting terms from July 2011 through September 2014 and exercisable at various dates through September 2019.

The fair value of each option granted is estimated on the date of grant using the Black-Scholes option-pricing method. The Company uses historical data to estimate the expected price volatility, the expected option life and the expected forfeiture rate. The Company has not made any dividend payments nor does it have plans to pay dividends in the foreseeable future. The following assumptions were used to estimate the fair value of options granted during the three months ended September 30, 2012 and the year ended June 30, 2012 using the Black-Scholes option-pricing model:

	FY 2013	FY 2012
Expected life of option (years)	4	2.5
Risk-free interest rate	.46 - .54%	.24 - .55%
Assumed volatility	104%	103 - 107%
Expected dividend rate	0	0
Expected forfeiture rate	4.19 - 6.66%	4.35 - 6.80%

Time-vested and performance-based stock awards, including stock options, restricted stock and restricted stock units, are accounted for at fair value at date of grant. Compensation expense is recognized over the requisite service and performance periods.

A summary of the status of unvested employee stock options as of September 30, 2012 and June 30, 2012 and the changes during the periods then ended is presented below:

NOTE 11 – EQUITY

On August 30, 2010, the Company entered into an amended and restated securities purchase agreement (“Socius Agreement”) with Socius CG II, Ltd. (“Socius”). Pursuant to the Socius Agreement, the Company had the right over a term of two years, subject to certain conditions, to require Socius to purchase up to $10 million of redeemable subordinated debentures and/or shares of redeemable Series A preferred stock in one or more tranches. The debentures accrued interest at an annual rate of 10% and the shares of Series A preferred stock accumulated dividends at the same rate. Both the debentures and the shares of Series A preferred stock were redeemable at the Company’s election at any time after the one year anniversary of issuance. Neither the debentures nor the Series A preferred shares were convertible into common stock.

On November 10, 2010, the Company’s Board of Directors approved a certificate of designation of preferences, rights and limitations to authorize shares of Series A preferred stock in accordance with the terms of the Socius Agreement. Upon the authorization of Series A preferred stock and in accordance with the terms of the Socius Agreement, the $517,168 of outstanding debentures issued by the Company to Socius CG II, Ltd. on September 2, 2010, and $7,510 of accrued interest were exchanged into 52.468 shares of Series A preferred stock. Following the authorization of the Series A Preferred Stock all future tranches under the Socius Agreement involved shares of Series A preferred stock instead of debentures.

Under the Socius Agreement, in connection with each tranche, Socius was obligated to purchase that number of shares of our common stock equal in value to 135% of the amount of the tranche at a per share price equal to the closing bid price of the common stock on the trading day preceding our delivery of the tranche notice. Socius had the option to pay for the shares it purchased at its option, in cash or a collateralized promissory note. Any such promissory note accrued interest at 2.0% per year and was collateralized by securities owned by Socius with a fair market value equal to the principal amount of the promissory note. The entire principal balance and interest on the promissory note was due and payable on the later of the fourth anniversary of the date of the promissory note or when we redeemed all the Series A preferred stock issued by us to Socius under the Socius Agreement, and was applied by us toward the redemption of the shares of Series A preferred stock held by Socius.

Under the terms of the Socius Agreement, the Company was obligated to pay Socius a commitment fee in the form of shares of common stock or cash, at the option of the Company, in the amount of $500,000 if it is paid in cash and $588,235 if it is paid in shares of common stock. Payment of the commitment fee occurred 50% at the closing of the first tranche and 50% at the closing of the second tranche.

The following summarizes the transactions under the Socius agreement:

Tranche	Date of Notice	Series A Preferred Stock Purchased by Socius		Shares of Common Stock Purchased by Socius		Total Purchase Price of Common Stock		Per Share Price		Shares of Common Stock Issued by ZBB in Payment of Commitment Fee		Discount on Collateralized Promissory Note Issued by Socius

		$	5,744,408		8,693,531	$	7,754,952				893,097	$	2,037,977

The Company’s accounting for the 2% notes receivable – common stock was to accrue interest on the discounted notes receivable at 10% as a credit to additional paid-in capital. The Company’s accounting for the Series A preferred stock was to accrete dividends at 10% as a charge to additional paid-in capital.

In the event of liquidation, dissolution or winding up (whether voluntary or involuntary) of the Company, the holders of shares of Series A preferred stock were entitled to be paid the full amount payable on such shares upon the liquidation, dissolution or winding up of the corporation fixed by the Board of Directors with respect to such shares, if any, before any amount was to be paid to the holders of the common stock.

In connection with the May 2012 Note transaction described in Note 8, on May 7, 2012 the Company sent a notice to Socius to terminate the Socius Agreement.

In June 2012, we entered into a redemption agreement with Socius pursuant to which we acquired and redeemed all the shares of Series A Preferred Stock issued to Socius under the Socius Agreement (the “Shares”) in exchange for the cancellation of the secured promissory notes issued by Socius to us under the Socius Agreement. Following completion of the June 2012 redemption and the retirement and cancellation of the Shares, no shares of Series A Preferred Stock remain outstanding. Subsequent to June 30, 2012, we cancelled the Series A preferred stock.

The liquidation preference of the outstanding Series A preferred stock was $0 and $3,715,470 as of June 30, 2012 and June 30, 2011, respectively. Redemption of the preferred shares was settled by application of the Socius 2% notes receivable.

On December 13, 2011, the Company entered into Stock Purchase Agreements with a strategic investor previously known to the Company and certain Company officers and directors providing for the issuance of a total of 1,167,340 shares of common stock for an aggregate purchase price of $875,505 at a price per share equal to $0.75 which was the closing price of the Company’s common stock on December 12, 2011. On December 14, 2011, the Company entered into Stock Purchase Agreements with certain investors providing for the issuance of a total of 1,425,000 shares of the Company’s common stock for an aggregate purchase price of $1,011,893 at a price per share of $0.7101 which was the closing price of the Company’s common stock on December 13, 2011. The closing for both transactions took place on December 16, 2011. The net proceeds to the Company after deducting $84,343 of offering costs were $1,803,055.

On January 31, 2012 and February 1, 2012, the Company entered into Stock Purchase Agreements with certain investors including certain members of the Company’s Board of Directors and management providing for the issuance of a total of 4,431,603 shares of the Company’s common stock for an aggregate purchase price of $3,165,000 at a weighted average price per share of $0.71. The closing took place on February 7, 2012. The net proceeds to the Company, after deducting $308,049 of offering costs, were $2,856,954.

On June 19, 2012 the Company issued 31,600,000 shares of its common stock at a price to the public of $0.38 per share. The net proceeds to ZBB from this offering were approximately $10.7 million after deducting approximately $1.3 million in underwriting discounts and other offering expenses. In connection with the offering, the Company granted the underwriter warrants to purchase 2,895,303 shares of common stock at an exercise price of $0.475 per share. These warrants expire on June 13, 2017. The estimated fair value of these warrants was $1,024,726, as determined using the Black-Scholes methodology (assuming estimated volatility of 100.86%, risk-free interest rate of 0.71%, expected dividend yield of 0.0%). This amount was recorded as both an increase to additional paid in capital and as a non-cash issuance cost of the financing transaction.

On July 5, 2012 the underwriter for the Company’s June 2012 underwritten public offering exercised substantially all of its over-allotment option and purchased an additional 4,591,287 shares of the Company's common stock. The net proceeds to the Company from this issuance were $1.6 million after deducting approximately $143,000 in offering expenses.

The employment contracts generally have no set term and can be terminated by either party. There is a provision for payments of nine months to eighteen months of annual salary as severance if we terminate a contract without cause, along with the acceleration of certain unvested stock option grants.

NOTE 13 - RETIREMENT PLANS

All Australian based employees are entitled to varying degrees of benefits on retirement, disability, or death. The Company contributes to an accumulation fund on behalf of the employees under an award which is legally enforceable. For U.S. employees, the Company has a 401(k) plan. All active participants are 100% vested immediately. Expenses under these plans were $30,453 and $15,460 for the three months ended September 30, 2012 and September 30, 2011, respectively.

NOTE 14— INCOME TAXES

The provision (benefit) for income taxes consists of the following:

	Three months ended September 30,
	2012		2011
Current	$	-	$	(70,000	)
Deferred		-		-
Provision (benefit) for income taxes	$	-	$	(70,000	)

The Company accounts for income taxes using an asset and liability approach which generally requires the recognition of deferred income tax assets and liabilities based on the expected future income tax consequences of events that have previously been recognized in the Company’s financial statements or tax returns. In addition, a valuation allowance is recognized if it is more likely than not that some or all of the deferred income tax assets will not be realized in the foreseeable future. Deferred income tax assets are reviewed for recoverability based on historical taxable income, the expected reversals of existing temporary differences, tax planning strategies and projections of future taxable income. As a result of this analysis, the Company has provided for a valuation allowance against its net deferred income tax assets as of September 30, 2012 and September 30, 2011.

The Company’s combined effective income tax rate differed from the U.S. federal statutory income rate as follows:

	Three months ended September 30,
	2012	2011
Income tax benefit computed at the U.S. federal statutory rate	-34%	-34%
Australia research and development credit	0	-4
Change in valuation allowance	34	34
Total	0%	-4%

Significant components of the Company’s net deferred income tax assets as of September 30, 2012 and June 30, 2012 were as follows:

	September 30, 2012			June 30, 2012
Federal net operating loss carryforwards	$	17,898,721		$	17,063,374
Federal - other		1,553,682			1,578,175
Wisconsin net operating loss carryforwards		2,206,508			2,080,223
Australia net operating loss carryforwards		1,568,110			1,291,699
Deferred income tax asset valuation allowance		(23,227,021	)		(22,013,471	)
Total deferred income tax assets	$	-		$	-

The Company has U.S. federal net operating loss carryforwards of approximately $53 million as of September 30, 2012, that expire at various dates between June 30, 2015 and 2033. The Company also has $1,054,202 in other federal deferred tax assets comprised of charitable contributions carryforwards and intangible amortization. The Company has U.S. federal research and development tax credit carryforwards of approximately $87,000 as of September 30, 2012 that expire at various dates through June 30, 2032. As of September 30, 2012, the Company has approximately $42 million of Wisconsin net operating loss carryforwards that expire at various dates between June 30, 2013 and 2028. As of June 30, 2012, the Company also has approximately $5.2 million of Australian net operating loss carryforwards available to reduce future taxable income of its Australian subsidiaries with an indefinite carryforward period.

A reconciliation of the beginning and ending balance of unrecognized income tax benefits is as follows:

	September 30, 2012		June 30, 2012
Beginning balance	$	208,593	$	219,500
Effect of foreign currency translation		7,979		(10,907	)
Ending balance	$	216,572	$	208,593

The unrecognized income tax benefits relate to the credit the Company claimed during fiscal 2011 related to a refundable Australian research and development tax credit for qualified expenditures incurred during fiscal year 2010. If recognized, it would favorably affect the effective income tax rate. The amount is included in accrued expenses in the accompanying consolidated balance sheets.

The Company’s issuance of additional shares of common stock has constituted ownership changes under Section 382 of the Internal Revenue Code which places an annual dollar limit on the use of net operating loss (“NOL”) carryforwards and other tax attributes that may be utilized in the future. The calculation of the annual limitation of usage is based on a percentage of the equity value immediately after any ownership change. The annual amount of tax attributes that may be utilized after the change in ownership is limited. Previous issuances of additional shares of common stock also resulted in ownership changes and the annual amount of tax attributes from previous years is limited as well. The extent of any limitations on the usage of net operating losses has not been determined.

NOTE 15 — SUBSEQUENT EVENTS

At the annual of meeting of shareholder held on November 7, 2012 the Company’s shareholders approved the following:

●	An amendment of the 2010 Omnibus Long-Term Incentive Plan (“Omnibus Plan”) which increased the number of shares of the Company’s common stock available for issuance pursuant to awards under the Omnibus Plan by 4,500,000 shares.

We provide advanced electrical power management platforms targeted at the growing global need for distributed renewable energy, energy efficiency, power quality, and grid modernization. We and our power electronics subsidiary, Tier Electronics, have developed a portfolio of intelligent power management platforms that directly integrate multiple renewable and conventional onsite generation sources with rechargeable zinc bromide flow batteries and other storage technology. We also offer advanced systems to directly connect wind and solar equipment to the grid and systems that can form various levels of micro-grids. Tier Electronics participates in the energy efficiency markets through its hybrid vehicle control systems, and power quality markets with its line of regulation solutions. Together, these platforms solve a wide range of electrical system challenges in global markets for utility, governmental, commercial, industrial and residential end customers.

On August 30, 2011, we entered into agreements providing for establishment of a joint venture to develop, produce, sell, distribute and service advanced storage batteries and power electronics in China (the “Joint Venture”). Joint Venture partners include PowerSav, Inc., AnHui Xinlong Electrical Co. and Wuhu Huarui Power Transmission &Transformation Engineering Co.

The Joint Venture was established in November 2011 and operates through a jointly-owned company located in Wuhu City, Anhui Province named Anhui Meineng Store Energy Co., Ltd. (the “JV Company”). The JV Company will initially assemble and ultimately manufacture the Company’s products for sale in the power management industry on an exclusive basis in mainland China and on a non-exclusive basis in Hong Kong and Taiwan.

The JV Company has been capitalized with approximately $13.6 million of equity capital, which includes approximately $9.5 million of cash and a contribution of technology from us to the JV Company via a license agreement (the “License Agreement”) valued at approximately $4.1 million by the JV Company. Our indirect interest in the JV Company equals approximately 33%.

Our investment in the JV Company was made through ZBB PowerSav Holdings Limited, a Hong Kong limited liability company, a holding company formed with PowerSav (“Hong Kong Holdco”). We own 60% of Hong Kong Holdco’s equity interests. We have the right to appoint a majority of the members of the Board of Directors of Hong Kong Holdco and Hong Kong Holdco has the right to appoint a majority of the members of the Board of Directors of the JV Company.

Pursuant to a management services agreement Hong Kong Holdco will provide certain management services to the JV Company in exchange for a management services fee equal to five percent of the JV Company’s net sales for the first five years and three percent of the JV Company’s net sales for the subsequent three years.

Pursuant to the License Agreement, the Company has granted to the JV Company (1) an exclusive royalty-free license to manufacture and distribute our Version 3 battery Module and ZBB EnerSection™ POWR PECC (up to 250KW) (the “Products”) in mainland China in the power supply management industry and (2) a non-exclusive royalty-free license to manufacture and distribute the Products in Hong Kong and Taiwan in the power supply management industry.

Pursuant to a research and development agreement, the JV Company may request us to provide research and development services upon commercially reasonable terms and conditions. The JV Company would pay our fully-loaded costs and expense incurred in providing such services.

Risks and Uncertainties

The following discussion of the consolidated financial position and results of operations of the Company should be read in conjunction with the consolidated financial statements and notes thereto included elsewhere in this form 10-Q and the Company’s annual report filed on form 10-K for the fiscal year ended June 30, 2012. In addition to historical information, this discussion contains forward-looking statements such as statements of the Company’s expectations, plans, objectives and beliefs. These statements use such words as “may,” “will,” “expect,” “anticipate,” “believe,” “plan,” and other similar terminology. In addition to the risks and uncertainties faced generally by participants in the renewable energy industry, we face the following risks and uncertainties:

●	Our stock price could be volatile and our trading volume may fluctuate substantially.

●	We have incurred losses and anticipate incurring continuing losses.

●	We may need additional financing.

●	Our industry is highly competitive and we may be unable to successfully compete.

●	Our ability to achieve significant revenue growth will be depended on the successful commercialization of our new products, including our third generation ZBB EnerStore™, zinc bromide flow batter and ZBB EnerSection™ power and energy control center.

●	To achieve profitability, we will need to lower our costs and increase our margins, which we may not be able to do.

●	If our products do not perform as promised, we could experience increased costs, lower margins and harm to our reputation.

●	To succeed, we will need to rapidly grow and we may not be successful in managing this rapid growth.

●	Our relationships with our strategic partners may not be successful and we may not be successful in establishing additional partnerships, which could adversely affect our ability to commercialize our products and services.

●	Shortages or delay of supplies of component parts may adversely affect our operating results until alternate sources can be developed.

●	We have no experience manufacturing our products on a large-scale basis and may be unable to do so at our manufacturing facilities.

●	Our China joint venture could be adversely affected by the laws and regulations of the Chinese government, our lack of decision-making authority and disputes between us and the Joint Venture.

●	Business practices in Asia may entail greater risk and dependence upon the personal relationships of senior management than is common in North America, and therefore some of our agreements with other parties in China and South Korea could be difficult or impossible to enforce.

●	Our success depends on our ability to retain our managerial personnel and to attract additional personnel.

●	We market and sell, and plan to market and sell, our products in numerous international markets. If we are unable to manage our international operations effectively, our business, financial condition and results of operations could be adversely affected.

●	Our financial results may vary significantly from period-to-period due to long and unpredictable sales cycles for some of our products and the cyclical nature of certain end-markets into which we sell our products, which may in turn lead to volatility in our stock price.

●	Businesses and consumers might not adopt alternative energy solutions as a means for obtaining their electricity and power needs, and therefore our revenues may not increase, and we may be unable to achieve and then sustain profitability.

●	The success of our business depends on our ability to develop and protect our intellectual property rights, which could be expensive.

●	We may be subject to claims that we infringe the intellectual property rights of others, and unfavorable outcomes could harm our business.

●	If our shareholders’ equity falls below the minimum requirement, our common stock may be delisted from the NYSE MKT, which would cause our common stock to become less liquid.

●	We may engage in acquisitions that could disrupt our business, cause dilution to our stockholder and reduce our financial resources.

●	We have never paid cash dividends and do not intend to do so.

For further information concerning these risks and uncertainties see the Risk Factors sections of our Annual Report on Form 10-K for the year ended June 30, 2012 and in any subsequently filed Quarterly Reports on Form 10-Q.

New Accounting Pronouncements

Refer to Note 1 of the Notes to Condensed Consolidated Financial Statements for a discussion of recently issued accounting pronouncements.

Critical Accounting Policies and Estimates

The preparation of our financial statements conforms to accounting principles generally accepted in the United States of America, which requires management, in applying our accounting policies, to make estimates and judgments that have an important impact on our reported amounts of assets, liabilities, revenue, expenses and related disclosures at the date of our financial statements. On an on-going basis, management evaluates its estimates including those related to bad debts, inventory valuations, warranty obligations and income taxes. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from management’s estimates. During the current reporting period we adopted the new guidance related to the reporting of other comprehensive income (loss). Since June 30, 2012, there have been no other significant changes to our critical accounting policies discussed in our Annual Report on Form 10-K for the fiscal year ended June 30, 2012. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America and related disclosures require management to make estimates and assumptions.

Results of Operations

Three months ended September 30, 2012 compared with the three months ended September 30, 2011

Revenue:

Our revenues for the three months ended September 30, 2012 and September 30, 2011 were $1,823,321 and $1,637,857, respectively. The increase of $185,464 was the result of a $1,379,031 increase in commercial product sales and a $1,193,567 decrease in engineering and development revenues as compared to the three months ended September 30, 2011. The increase in commercial product sales principally consisted of sales of ZBB EnerStore and ZBB EnerSection systems which we began selling in the quarter ended March 31, 2012 and engineering and development revenues related to the Company’s joint development and license agreement with a global technology company. Engineering and development revenues for the 2012 period consisted primarily of revenue recognized under the Honam Collaboration agreement which was recognized over the performance period through June 2012.

Costs and Expenses:

Total costs and expenses for the three months ended September 30, 2012 and September 30, 2011 were $4,719,380 and $3,334,339, respectively. This increase of $1,385,041 in the three months ended September 30, 2012 was primarily due to the following factors:

●	a $1,335,721 increase in costs of product sales was due to an increase in commercial product sales;

●	a $436,042 decrease in costs of engineering and development sales was due to diminished activities related to engineering and development agreements;

●	a $460,356 increase in advanced engineering and development expenses due to a shift from engineering contracts to product development and pilot plant operation for the Company’s ZBB Enerstore and ZBB Enersection products.

Other Expense:

Total Other Expense for the three months ended September 30, 2012 increased by $74,689 to $123,655 from $48,996 for the three months ended September 30, 2011 primarily as a result of a $76,481 equity in loss of investee company.

Income Taxes (Benefit):

Benefit for income taxes during the three months ended September 30, 2012 decreased by $70,000 to $0 from $70,000 for the three months ended September 30, 2011. Benefit for income taxes represents an estimate of a refundable research and development tax credit we expect to receive from the government of Australia for the fiscal year ending June 30, 2012 related to the qualified expenditures we incurred during the year ended June 30, 2012.

Net Loss:

Our net loss for the three months ended September 30, 2012 increased by $1,207,342 to $2,882,790 from the $1,675,448 net loss for the three months ended September 30, 2011. This increase in loss was primarily the result of increases in expenses as described above. For the three months ended September 30, 2012 there was a net loss of $136,924 attributable to noncontrolling interest.

Liquidity and Capital Resources

Since our inception, our research, advanced engineering and development, and operations have been primarily financed through debt and equity financings, and government and other research and development contracts. Total paid in capital as of September 30, 2012 was $82,931,121 and $81,093,292 as of June 30, 2012. We had a cumulative deficit of $71,936,699 as of September 30, 2012 compared to a cumulative deficit of $69,053,909 as of June 30, 2012. At September 30, 2012 we had working capital of $4,764,439 compared to June 30, 2012 working capital of $5,727,309. Our shareholders’ equity as of September 30, 2012 and June 30, 2012 was $9,409,742 and $10,454,462, respectively.

At September 30, 2012, our principal sources of liquidity were our cash and cash equivalents which totaled $4,637,014 and accounts receivable of $1,189,722.

In June 2012 we completed an underwritten public offering of 31,600,000 shares of common stock at a price to the public of $0.38 per share for net proceeds of $10.7 million. In connection with the offering, the Company granted the underwriter warrants to purchase 2,895,303 shares of common stock at an exercise price of $0.475 per share. These warrants expire on June 13, 2017. The estimated fair value of these warrants was $1,024,726, as determined using the Black-Scholes methodology (assuming estimated volatility of 100.86%, risk-free interest rate of 0.71%, expected dividend yield of 0.0%). This amount was recorded as both an increase to additional paid in capital and as a non-cash issuance cost of the financing transaction. During the year ended June 30, 2012 we also sold an additional 11,478,666 shares of common stock in various transactions for net proceeds of $4.8 million.

On August 30, 2010 we entered into an amended and restated securities purchase agreement (the “Socius Agreement”) with Socius CG II, Ltd. (“Socius”) pursuant to which we had the right over a term of two years, subject to certain conditions, to require Socius to purchase up to $10 million of 10% redeemable subordinated debentures and/or shares of 10% redeemable Series A preferred stock in tranches. Under the Socius Agreement, in connection with each tranche Socius was obligated to purchase a number of shares of our common stock equal in value to 135% of the amount of the tranche at a per share price equal to the closing bid price of the common stock on the trading day preceding our delivery of the tranche notice. We cancelled the Socius agreement on May 7, 2012.

During the year ended June 30, 2012 we delivered a total of three tranche notices under the Socius Agreement pursuant to which Socius purchased $2,197,240 of shares of Series A preferred stock. In connection with the tranches, Socius purchased 4,132,553 shares of common stock for a total purchase price of $2,966,275 and at a weighted average per share purchase price of $0.72. Socius paid for the shares of common stock it purchased with secured promissory notes.

In June 2012, we entered into a redemption agreement with Socius pursuant to which we acquired and redeemed all the shares of Series A Preferred Stock issued to Socius under the Socius Agreement in exchange for the cancellation of the secured promissory notes issued by Socius to us under the Socius Agreement. Following completion of the June 2012 redemption and the retirement and cancellation of the Shares, no shares of Series A Preferred Stock remain outstanding. Subsequent to June 30, 2012, we cancelled the Series A preferred stock.

In July 2012 the underwriter for the Company’s June 2012 underwritten public offering exercised substantially all of its over-allotment option and purchased an additional 4,591,287 shares of the Company's common stock. The net proceeds to the Company from this issuance were $1.6 million after deducting approximately $143,000 in offering expenses.

If we are able to signficantly grow our product revenues in the remaining quarters of fiscal 2013 we believe that cash and cash equivalents on hand at September 30, 2012 and other sources of cash will be sufficient to fund our operations through the end of fiscal 2013. However, if our product revenues remain at current levels we will likely require additional investment capital or other funding during the third quarter of fiscal 2013 to maintain our current operations. If we are unable to obtain such needed funds, our financial condition and results of operations may be materially adversely affected and we may not be able to continue operations. Accordingly, we are currently implementing certain plans designed to generate additional sales and reduce costs and are exploring various alternatives including strategic partnership transactions that may be available to us.

Operating Activities

Our operating activities used net cash of $4,583,595 for the three months ended September 30, 2012. Cash used in operations resulted from a net loss of $3,019,714 reduced by $576,782 in non-cash adjustments and increased by $2,217,143 in net changes to working capital. Non-cash adjustments included $236,150 of stock-based compensation expense, and $340,632 of depreciation and amortization expense. Net changes in working capital were primarily due to increases in accounts receivable of $709,159, inventories of $919,521 and a decrease in customer deposits of $400,126 offset by an increase in accounts payable of $18,761 and accrued expenses of $20,465.

Investing Activities

Our investing activities used net cash of $87,691 for the three months ended September 30, 2012, due to the use of $87,691 for the purchase of property and equipment.

Financing Activities

Our financing activities provided net cash of $1,462,027 for the three months ended September 30, 2012. Net cash provided by financing activities was comprised primarily of $1,744,689 in proceeds from issuance of common stock less repayments of $141,153 of principal on bank loans and notes payable, and $143,009 in common stock issuance costs.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements as of September 30, 2012.
