EMCORE Corporation

Notes to our Condensed Consolidated Financial Statements

For the three and nine months ended June 30, 2015

(unaudited)

NOTE 1. Description of Business

Business Overview

EMCORE Corporation and its subsidiaries (referred to herein as the “Company”, “we”, “our”, or “EMCORE”) offers a broad portfolio of compound semiconductor-based products for the fiber optics market. We were established in 1984 as a New Jersey corporation and we have one reporting segment: Fiber Optics. EMCORE's Fiber Optics business provides optical components, subsystems and systems for high-speed telecommunications, Cable Television (CATV), Wireless and Fiber-To-The-Premises (FTTP) networks, as well as products for satellite communications, video transport and specialty photonics technologies for defense and homeland security applications. EMCORE's Solar Photovoltaics business, which was sold in December 2014, provided products for space power applications including high-efficiency multi-junction solar cells, Covered Interconnect Cells (CICs) and complete satellite solar panels. EMCORE sold certain assets, and transferred certain liabilities, of the Company's telecommunications business, including the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business, in January 2015. In addition to organic growth and development of our existing Fiber Optics market, we intend to pursue other strategies to enhance shareholder value, which may include acquisitions, investments in joint ventures, partnerships, and other strategic alternatives, such as dispositions, reorganizations, recapitalizations or other similar transactions. Accordingly, the Strategy Committee of the Board and our management may from time to time be engaged in evaluating potential strategic opportunities and may enter into definitive agreements with respect to such transactions or other strategic alternatives.

Basis of Presentation

On September 17, 2014, EMCORE entered into an Asset Purchase Agreement (the “Photovoltaics Agreement”) with SolAero Technologies Corporation ("SolAero") (formerly known as Photon Acquisition Corporation) pursuant to which the Company agreed to sell substantially all of the assets, and assume substantially all of the liabilities, primarily related to or used in connection with the Company’s photovoltaics business, including EMCORE's subsidiaries EMCORE Solar Power, Inc. and EMCORE IRB Company, LLC (collectively, the "Photovoltaics Business" and, the sale of the Photovoltaics Business, the "Photovoltaics Asset Sale") to SolAero for $150.0 million in cash, prior to a $0.1 million working capital adjustment pursuant to the Photovoltaics Agreement finalized and paid by EMCORE during the quarter ended June 30, 2015. On December 10, 2014, EMCORE completed the Photovoltaics Asset Sale.

On October 22, 2014, EMCORE entered into an Asset Purchase Agreement (the "Digital Products Agreement") with NeoPhotonics Corporation, a Delaware corporation ("NeoPhotonics"), pursuant to which the Company agreed to sell certain assets, and transfer certain liabilities, of the Company's telecommunications business (collectively, the "Digital Products Business" and, the sale of the Digital Products Business, the "Digital Products Assets Sale") to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain adjustments, consisting of $1.5 million in cash at closing and a promissory note in the principal amount of $16.0 million (the "Promissory Note").

On January 2, 2015, EMCORE and NeoPhotonics entered into Amendment No. 1 (the "APA Amendment") to the Digital Products Agreement dated October 22, 2014. Among other things, the APA Amendment revised the nature and timing of the financial deliverable requirements of the Company to NeoPhotonics under the original Digital Products Agreement. The assets sold pursuant to the Digital Products Agreement included certain fixed assets, inventory and intellectual property for the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business. On January 2, 2015, EMCORE completed the sale of the Digital Products Business. On April 16, 2015, EMCORE and NeoPhotonics entered into an agreement to adjust the purchase price resulting in an adjusted balance of the Promissory Note of $15.5 million. On April 17, 2015, NeoPhotonics prepaid the entire outstanding balance of the Promissory Note of $15.5 million, plus accrued interest of $0.2 million.

7

The Photovoltaics Asset Sale and Digital Products Asset Sale are reported as discontinued operations, which require retrospective restatement of prior periods to classify the results of operations as discontinued operations. We have also reclassified the assets and liabilities that were sold within the descriptions "assets of discontinued operations" and "liabilities of discontinued operations" within current and non-current assets and liabilities, respectively, on the condensed consolidated balance sheet as of September 30, 2014. No Photovoltaics or Digital Products assets or liabilities remain on the condensed consolidated balance sheet as of June 30, 2015. The financial results of the Photovoltaics Business and the Digital Products Business are presented as "discontinued operations" on the condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended June 30, 2015 and 2014. See also Note 3 - Discontinued Operations. The notes to our condensed consolidated financial statements relate to our continuing operations only, unless otherwise indicated.

Beginning in the first quarter of fiscal year 2015, the Company operates as a single reportable segment.

Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information, and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and notes required by U.S. GAAP for annual financial statements. In our opinion, the interim financial statements reflect all normal adjustments that are necessary to provide a fair presentation of the financial results for the interim periods presented. Operating results for interim periods are not necessarily indicative of results that may be expected for an entire fiscal year. The condensed consolidated balance sheet as of September 30, 2014 has been derived from the audited consolidated financial statements as of such date as adjusted for discontinued operations. Also see Note 3 - Discontinued Operations. For a more complete understanding of our business, financial position, operating results, cash flows, risk factors and other matters, please refer to our Annual Report on Form 10-K for the fiscal year ended September 30, 2014.

All significant intercompany accounts and transactions have been eliminated in consolidation. We are not the primary beneficiary of, nor do we hold a significant variable interest in, any variable interest entity. We have evaluated subsequent events through the date that the financial statements were issued.

Sale of Fiber Optics-related Assets

On March 27, 2012, we entered into a Master Purchase Agreement with a subsidiary of Sumitomo Electric Industries, LTD (SEI), pursuant to which we agreed to sell certain assets and transfer certain obligations associated with our Fiber Optics segment. On May 7, 2012, we completed the sale of these assets to SEI and recorded a gain of approximately $2.8 million. Under the terms of the Master Purchase Agreement, we have agreed to indemnify SEI for up to $3.4 million of potential claims and expenses for the two-year period following the sale and we have recorded this amount as a deferred gain on our balance sheet as of June 30, 2015 and September 30, 2014 as a result of these contingencies. SEI paid $13.1 million in cash and deposited approximately $2.6 million into escrow as security for indemnification obligations and any purchase price adjustments. During the fiscal year ended September 30, 2013, we resolved the purchase price contingencies resulting in the reduction of the purchase price by $1.1 million. The reduced purchase price is recorded as an offset to the escrow receivable of $2.6 million. There remains a deferred gain of $3.4 million related to our indemnification obligation to SEI and an escrow receivable of $1.5 million as of June 30, 2015 as claims have been made under the Master Purchase Agreement against these balances prior to the end of the indemnification period in May 2014. We are not able to determine at this time the outcome of any potential settlements associated with the remaining claims and as a result have not recorded any related adjustments to the deferred gain amount.

Liquidity and Capital Resources

Historically, we have consumed cash from operations and incurred significant net losses. We have managed our liquidity position through a series of cost reduction initiatives, borrowings from our credit facility, capital markets transactions, and the sale of assets.

As of June 30, 2015, cash and cash equivalents totaled $114.1 million and net working capital totaled approximately $126.4 million. Net working capital, calculated as current assets minus current liabilities, is a financial metric we use which represents available operating liquidity. For the nine months ended June 30, 2015, we earned net income of $61.6 million.

8

In April 2015, EMCORE's Board of Directors authorized the Company to repurchase $45.0 million of its common stock. On May 15, 2015, we announced the commencement of a modified "Dutch auction" tender offer to purchase for cash shares of our common stock (the "Tender Offer"). On June 15, 2015, we completed the Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses. Repurchased common stock were recorded to treasury stock. The Company incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock.

With respect to measures taken to improve liquidity:

• Sale of Photovoltaics Business: On December 10, 2014, we completed the sale of our Photovoltaics Business for$150.0 million in cash prior to working capital adjustments of $0.1 million. These proceeds will provide us with working capital for fiscal year 2015 and beyond.

• Sale of Digital Products Business: On January 2, 2015, we completed the sale of our Digital Products Business for $1.5 million in cash and an adjusted Promissory Note balance of $15.5 million. On April 17, 2015, NeoPhotonics paid in full the outstanding balance of the Promissory Note of $15.5 million, plus accrued interest of $0.2 million.

• Credit Facility: On November 11, 2010, we entered into a Credit and Security Agreement (credit facility) with Wells Fargo Bank, National Association ("Wells Fargo"). The credit facility, as it has been amended through its sixth amendment, currently provides us with a revolving credit of up to $15.0 million through November 2015 that can be used for working capital requirements, letters of credit, and other general corporate purposes. The credit facility is secured by the Company's assets and is subject to a borrowing base formula based on the Company's eligible accounts receivable, inventory, and machinery and equipment accounts.

On December 3, 2014, we entered into a Sixth Amendment to the credit facility, pursuant to which Wells Fargo agreed, to automatically release all encumbrances covering certain of the Company’s assets to be sold pursuant to the Photovoltaics Agreement and the Digital Products Agreement. In addition, on December 10, 2014 upon notice to Wells Fargo of the closing of the transaction contemplated by the Photovoltaics Agreement, the maximum borrowing allowed under the credit facility was reduced from $35.0 million to $15.0 million, and certain other changes to the borrowing base calculations went into effect.

NOTE 2. Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements that are of significance, or of potential significance, to us other than those discussed below:

• In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This standard changes the criteria for reporting discontinued operations. Under the accounting standard update, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity's operations and financial results when either it qualifies as held for sale, disposed of by sale, or disposed of other than by sale. In addition, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. While early adoption is allowed, we have determined that we would not early adopt and as a result this accounting standard update will be effective for our fiscal year beginning on October 1, 2015. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

• In May 2014, as part of its ongoing efforts to assist in the convergence of U.S. GAAP and International Financial Reporting Standards, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Under the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. On July 9, 2015, the FASB voted to defer the effective date of implementation by one year. The new standard will be effective for us beginning October 1, 2018 and early adoption is permitted as of October 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We anticipate this standard will not have a material impact on our Condensed Consolidated Financial Statements.

• In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The standard provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. In addition, the standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The guidance is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. This accounting standard update will be effective for our fiscal year beginning October 1, 2017. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

• In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The standard simplifies the subsequent measurement of inventory. This standard requires inventory to be measured at the lower of cost and net realizable value and applies only to inventories for which cost is determined by methods other than last-in-first-out and the retail inventory method. Under this guidance, net realizable value is one of several calculations an entity needs to make to measure inventory at lower of cost or market. The guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. Early adoption is permitted. The new standard will be effective for our fiscal year beginning October 1, 2017. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

NOTE 3. Discontinued Operations

Sale of Photovoltaics Business

The financial results of the Photovoltaics Business are reported as discontinued operations for the three and nine months ended June 30,2015 and 2014, respectively. In connection with this transaction, we sold net assets of $60.3 million to SolAero and incurred transaction costs of $2.7 million. During the three months ended December 31, 2014, we recognized a gain of $56.8 million, net of tax on the sale of the Photovoltaics Business which is recorded within discontinued operations in the condensed consolidated statements of operations and comprehensive income (loss). During the three months ended June 30, 2015, we made a payment of $0.1 million to SolAero to complete the working capital adjustment under the agreement. During the three and nine months ended June 30, 2015, we recognized gains of $0.2 million and $0.4 million, respectively, associated with the settlement of outstanding obligations on retained Photovoltaic product warranties.

We have classified the assets and liabilities that were sold as "assets of discontinued operations" and "liabilities of discontinued operations" within current and non-current assets and liabilities, respectively, on the condensed consolidated balance sheet as of September 30, 2014. As of September 30, 2014, the carrying amount of goodwill related to the Photovoltaics Business was $20.4 million and this balance was reclassified to non-current assets of discontinued operations.

Sale of Digital Products Business

On October 22, 2014, EMCORE entered into the Digital Products Agreement with NeoPhotonics pursuant to which the Company agreed to sell certain assets, and transfer certain liabilities of the Company's Digital Products Business to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain purchase price adjustments, consisting of $1.5 million in cash at closing and a promissory note in the principal amount of $16.0 million (the "Promissory Note"). The Promissory Note provided that it would bear interest of 5.0% per annum for the first year and 13.0% per annum for the second year, payable semi-annually in cash, and would mature two years from the closing of the transaction. In addition, the Promissory Note was subject to prepayments under certain circumstances, and is secured by certain of the assets sold to NeoPhotonics in the transaction.

On January 2, 2015, EMCORE and NeoPhotonics entered into the APA Amendment. Among other things, the APA Amendment revised the nature and timing of the financial deliverable requirements of the Company to NeoPhotonics under the original Digital Products Agreement. The assets sold pursuant to the Digital Products Agreement included certain fixed assets, inventory and intellectual property for the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business. On January 2, 2015, EMCORE completed the sale of the Digital Products Business. On April 16, 2015, EMCORE and NeoPhotonics entered into an agreement to adjust the purchase price resulting in an adjusted balance of the Promissory Note of $15.5 million. On April 17, 2015, NeoPhotonics prepaid the outstanding balance of the Promissory Note of $15.5 million, plus accrued interest of $0.2 million.

The financial results of the Digital Products Business are reported as discontinued operations for the three and nine months ended June 30, 2015 and 2014. In connection with this transaction, we sold net assets of $13.3 million to NeoPhotonics and incurred transaction costs of $1.6 million. During the nine months ended June 30, 2015, we recognized a gain of $2.0 million on the sale of the Digital Products Business which is recorded within discontinued operations in the condensed consolidated statements of operations and comprehensive income (loss).

We have classified the assets and liabilities that were sold within the descriptions "assets of discontinued operations" and "liabilities of discontinued operations" within current and non-current assets and liabilities, respectively, on the condensed consolidated balance sheet as of September 30, 2014. No Digital Products assets or liabilities remain on the condensed consolidated balance sheet as of June 30, 2015.

NOTE 4. Fair Value Accounting

ASC 820, Fair Value Measurements, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

• Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument.

• Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value.

A financial asset or liability's classification within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

13

Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The following table lists our financial assets and liabilities that are measured at fair value on a recurring basis:

Fair Value Measurement
(in thousands)	Level 1		Level 2	Level 3
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Remaining Inputs	Significant Unobservable Inputs	Total
As of June 30, 2015
Assets:
Cash and cash equivalents	$	114,129	—	—	$	114,129
Restricted cash	26		—	—	26
Liabilities:
Warrant liability	—		—	—	—
As of September 30, 2014
Assets:
Cash and cash equivalents	$	20,687	—	—	$	20,687
Restricted cash	1,482		—	—	1,482
Liabilities:
Warrant liability	—		122	—	122

Cash consists primarily of bank deposits or, occasionally, highly liquid short-term investments with a maturity of three months or less at the time of purchase.

Restricted cash represents temporarily restricted deposits held as compensating balances against short-term borrowing arrangements.

As of September 30, 2014, warrants representing the right to purchase 400,001 shares, of our common stock were outstanding. The warrants expired on April 1, 2015. All of our warrants met the classification requirements for liability accounting pursuant to ASC 815, Derivatives and Hedging. Historically, recording the change in the fair value of our warrants impacted our statements of operations and comprehensive income (loss) and was primarily due to the change in the closing price of our common stock.

The carrying amounts of accounts receivable, prepaid expenses and other current assets, borrowings from our credit facility, accounts payable, accrued expenses and other current liabilities approximate fair value because of the short maturity of these instruments.

NOTE 5. Accounts Receivable

The components of accounts receivable consisted of the following:

	As of			As of
(in thousands)	June 30, 2015			September 30, 2014

During the quarter ended December 31, 2014, as a result of a revision in the estimated amount of cash flows for asset retirement obligations ("ARO") relating to the extension of the Alhambra facility leases and changes in the required restoration efforts, the Company reduced its ARO liability by $2.9 million with an offsetting reduction to leasehold improvements of $2.1 million, and recorded a gain from change in estimate on ARO obligation of $0.8 million. Also see Note 12 - Commitments and Contingencies.

As of June 30, 2015, construction in progress included CATV product expansion and automation manufacturing assets. As of June 30, 2015 and September 30, 2014, accumulated depreciation was approximately $23.1 million and $21.5 million, respectively.

Income and other taxes: For the three months ended June 30, 2015, the Company reported $0.5 million of income tax expense from continuing operations income and $1.6 million of income tax benefit within income from discontinued operations. For the nine months ended June 30, 2015, the Company reported $1.9 million of income tax benefit from continuing operations losses and $26.5 million of income tax expense within income from discontinued operations. The income tax expense within discontinued operations includes estimated alternative minimum tax and other adjustments prescribed by ASC 740 in allocating expected annual income tax expense (benefit) between continuing operations and discontinued operations.

During the quarter ended December 31, 2014, the Company utilized $24.1 million of deferred tax assets. The Company expects to make a payment for alternative minimum taxes and the remaining income tax expense will be offset mainly through

16

utilization of $24.1 million of deferred tax assets and net operating loss carry forwards. Also see Note 11 - Income and other Taxes.

Severance and restructuring accruals: On November 15, 2013, Mr. Chris Larocca proposed to resign as the Company's Chief Operating Officer, effective as of November 30, 2013. The Company recorded a charge of $0.5 million in the nine months ended June 30, 2014 related to the separation agreement entered into as part of Mr. Larocca's resignation.

These payments are not contingent upon any future service by Dr. Hou. The Company recorded a charge of approximately $0.8 million in the fourth quarter of fiscal year 2014 related to Dr. Hou's Separation Agreement.

On December 10, 2014, Monica Van Berkel announced she would resign as the Company's Chief Administrative Officer, effective as of January 2, 2015 (the “Separation Date”).

The separation agreement provides for among other things, the continuation of her base salary for 74 weeks, benefits for 18 months, outplacement services for a period of not more than one year and with a value not in excess of $15,000 and immediate vesting of all her outstanding non-vested equity awards. These payments are not contingent upon any future service by Ms. Van Berkel. The Company recorded a charge of approximately $0.6 million in the first quarter of fiscal year 2015 related to Ms. Van Berkel's Separation Agreement.

On December 10, 2014, Alfredo Gomez announced he would resign as the Company's General Counsel and Secretary, effective as of February 13, 2015 or, if later, following the date on which the Company hires a successor in-house counsel (the “Separation Date”).

These payments are not contingent upon any future service by Mr. Gomez. The Company recorded a charge of approximately $0.5 million in the first quarter of fiscal year 2015 related to Mr. Gomez's Separation Agreement.

In connection with the closing of the sale of the Digital Products Business, we accrued for the remaining lease costs of our Newark, California facility through the lease termination of May 2016. Included in the discontinued operations for the nine months ended June 30, 2015, was $0.7 million related to the remaining lease costs.

Our severance and restructuring-related accruals specifically relates to the Separation Agreements and non-cancelable obligations associated with an abandoned leased facility. Expense related to severance and restructuring accruals is included in selling, general, and administrative expense on our statement of operations and comprehensive income (loss).

NOTE 10. Credit Facilities

On November 11, 2010, we entered into a Credit and Security Agreement (credit facility) with Wells Fargo Bank, National Association ("Wells Fargo"). The credit facility is secured by the Company's assets and is subject to a borrowing base formula based on the Company's eligible accounts receivable, inventory, and machinery and equipment accounts.

On December 3, 2014, we entered into a Sixth Amendment to the credit facility pursuant to which Wells Fargo agreed to automatically release all encumbrances covering certain of the Company’s assets to be sold pursuant to the Photovoltaics Agreement and the Digital Products Agreement. In addition, on December 10, 2014, upon notice to Wells Fargo of the closing of the transaction contemplated by the Photovoltaics Agreement, the maximum borrowing allowed under the credit facility was reduced from $35.0 million to $15.0 million, and certain other changes to the borrowing base calculations went into effect.

As of June 30, 2015, there was no outstanding balance under this credit facility with an interest rate of 3.3% and approximately $1.2 million reserved for four stand-by letters of credit under the credit facility.

NOTE 11. Income and other Taxes

At September 30, 2014, the Company determined that it was more likely than not that certain deferred tax assets would be realized upon the sale of the Photovoltaic Business in fiscal year 2015. As a result, a net deferred tax valuation allowance release of $24.1 million was recorded as an income tax benefit during fiscal year 2014. The sale of the Photovoltaic Business closed on December 10, 2014 and the Company realized a gain on the transaction.

For the three months ended June 30, 2015, the Company reported $0.5 million of income tax expense from continuing operations losses and $1.6 million of income tax benefit within income from discontinued operations. For the nine months ended June 30, 2015, the Company reported $1.9 million of income tax benefit from continuing operations losses and $26.5 million of income tax expense within income from discontinued operations. The income tax expense within discontinued operations includes estimated alternative minimum tax and other adjustments prescribed by ASC 740 in allocating expected annual income tax expense (benefit) between continuing operations and discontinued operations.

During the nine months ended June 30, 2015, the Company utilized $24.1 million of deferred tax assets. The Company paid alternative minimum taxes of $0.6 million in the three and nine months ended June 30, 2015 and the remaining income tax

18

expense will be offset mainly through utilization of $24.1 million of deferred tax assets and utilization of net operating loss carry forwards.

For the three months ended June 30, 2014, the Company reported $0.7 million of income tax benefit from losses from continuing operations and $0.7 million of income tax expense within income from discontinued operations. For the nine months ended June 30, 2014, the Company reported $1.4 million of income tax benefit from losses from continuing operations and $1.4 million of income tax expense within income from discontinued operations.

For the three months ended June 30, 2015, the effective tax rate was 49.6%, compared to 14.4% for the three months ended June 30, 2014. The higher tax rate for June 30, 2015 is primarily due to the methodology used for allocating income tax expense between continuing and discontinued operations under ASC 740. For the nine months ended June 30, 2015, the effective tax rate on continuing operations was 33.8%, compared to 9.7% for the nine months ended June 30, 2014 primarily due to the benefit of the loss from operations in 2015. In determining the effective tax rate, the Company uses estimates to forecast the results from continuing operations for the current fiscal year as well as permanent differences between book and tax accounting. The Company believes its forecast of losses from continuing operations is a reasonable estimate. Actual results from continuing operations may differ significantly from the estimates previously forecasted, resulting in significant changes from one period to the next in the tax expense or benefit from continuing operations being recognized.

The Company expects all remaining deferred tax assets will have a full valuation allowance at September 30, 2015. However, on a quarterly basis, the Company will evaluate the positive and negative evidence to assess whether the more likely than not criterion, mandated by ASC 740, has been satisfied in determining whether there will be further adjustments to the valuation allowance.

During the three and nine months ended June 30, 2015 and 2014, there were no material increases or decreases in unrecognized tax benefits and we do not anticipate any material increases or decreases in the amounts of unrecognized tax benefits for the remainder of fiscal year 2015. As of June 30, 2015 and September 30, 2014, we had approximately $493,000 and $445,000, respectively, of interest and penalties accrued as tax liabilities on our balance sheet.

We file income tax returns in the U.S. federal, state, and local jurisdictions. The Company's September 30, 2012, federal return was under examination by the Internal Revenue Service. The examination was completed in April 2015 and the Company was notified there were no changes to the originally filed return. There are no state income tax returns under examination. The following tax years remain open to assessment for each of the more significant jurisdictions where we are subject to income taxes: after fiscal year 2010 for the U.S. federal and the State of New Mexico, and after fiscal year 2009 for the state of California.

Included in discontinued operations during the three and nine months ended June 30, 2015 were $0.2 million of incentive tax credits received. Included in discontinued operations for the three and nine months ended June 30, 2014 were $0.2 million and $0.8 million, respectively, of New Mexico incentive tax credits received. The amount received was allocated to cost of goods sold, selling, general and administrative and research and development expense primarily based on the number of employees allocated to the related departments. These credits resulted in cash refunds and a reduction of future payroll and compensation taxes.

NOTE 12. Commitments and Contingencies

Operating Lease Obligations: We lease certain land, facilities, and equipment under non-cancelable operating leases. Operating lease amounts exclude renewal option periods, property taxes, insurance, and maintenance expenses on leased properties. Our facility leases typically provide for rental adjustments for increases in base rent (up to specific limits), property taxes, insurance, and general property maintenance that would be recorded as rent expense. Rent expense was approximately $0.3 million and $0.5 million for the three months ended June 30, 2015 and 2014, respectively, and approximately $1.0 million and $1.3 million for the nine months ended June 30, 2015 and 2014, respectively. There are no off-balance sheet arrangements other than our operating leases.

Asset Retirement Obligations ("ARO"): We have known conditional asset retirement conditions, such as certain asset decommissioning and restoration of rented facilities to be performed in the future. Our asset retirement obligations include assumptions related to renewal option periods for those facilities where we expect to extend lease terms. The Company recognizes its estimate of the fair value of its asset retirement obligations in the period incurred in long-term liabilities. The fair value of the asset retirement obligations is also capitalized as property, plant and equipment.

19

In future periods, the asset retirement obligation is accreted for the change in its present value and capitalized costs are depreciated over the useful life of the related assets. If the fair value of the estimated asset retirement obligation changes, an adjustment will be recorded to both the asset retirement obligation and the asset retirement capitalized cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, changes in estimated retirement costs, and changes in the estimated timing of settling asset retirement obligations. The fair value of our asset retirement obligations were estimated by discounting projected cash flows over the estimated life of the related assets using credit adjusted risk-free rates which ranged from 3.25% to 5.78%. There were no asset retirement obligations settled during the three and nine months ended June 30, 2015, and 2014. Accretion expense of $22,000 and $43,000 was recorded during the three months ended June 30, 2015, and 2014, respectively. Accretion expense of $89,000 and $128,000 was recorded during the nine months ended June 30, 2015, and 2014, respectively.

EMCORE leases a major facility in Alhambra, California covering six buildings where manufacturing, research and development, and general and administrative work is provided. Several leases related to these facilities, which expired in 2011, were being maintained on a month-to-month basis. In November 2014, a new lease for four of the six buildings was signed which was retroactively effective on October 1, 2014. The new lease extended the terms of the lease for three years plus a three year option to extend the lease and clarified the obligations and restoration work necessary to restore the buildings back to the requirements in the lease.

The Company’s asset retirement obligation for the leased Alhambra facilities consists of legal requirements to return the existing leased facilities to prescribed state and certain environmental work to be performed due to the presence of a manufacturing fabrication operation and significant changes to the facilities over the past thirty years. EMCORE had estimated a significant asset retirement obligation associated with this site.

During the first quarter of fiscal 2015, the Company completed an analysis of the new Alhambra lease and revised its estimated future cash flows of its asset retirement obligations. The analysis required estimating the probability or likelihood that the Company will be required to remove certain infrastructure and restore the leased properties as set forth in the new lease, and the timing and amount of those future costs. The analysis resulted in the downward revision of the Company’s asset retirement obligation liability. This change in the estimated cash flows resulted in a reduction in the asset retirement obligations liability by $2.9 million with an offsetting reduction to property, plant, and equipment of $2.1 million, and a gain from change in estimate of ARO obligation of $0.8 million. The Company first reduced the net leasehold improvement asset to the extent of the carrying amount of the related asset initially recorded when the asset retirement obligations were established. The amount of the remaining reduction to the asset retirement obligations was recorded as a reduction to operating expenses.

The following table summarizes asset retirement obligations activity.

Asset Retirement Obligations	June 30,
(in thousands)	2015
Balance at September 30, 2014	$	5,263
Asset retirement obligations reclassified to liabilities of discontinued operations	(720		)

Indemnifications: We have agreed to indemnify certain customers against claims of infringement of the intellectual property rights of others in our sales contracts with these customers. Historically, we have not paid any claims under these indemnification obligations. On September 19, 2013, we received written notice from a customer of our broadband products requesting indemnification relating to a lawsuit brought against them alleging patent infringement of a system incorporating our product. As of June 30, 2015, there has been no resolution to this claim.

20

In March 2012, we entered into a Master Purchase Agreement with SEI, pursuant to which we agreed to sell certain assets and transfer certain obligations associated with our Fiber Optics segment. Under the terms of the Master Purchase Agreement, we have agreed to indemnify SEI for up to $3.4 million of potential claims and expenses for the two-year period following the sale and we recorded this amount as a deferred gain on our balance sheet as of June 30, 2015 and September 30, 2014 as a result of these contingencies. In April 2013, May 2013 and May 2014, we received letters from SEI asserting indemnification claims under the Master Purchase Agreement. As of June 30, 2015, there has been no resolution to these claims. See Note 1 - Description of Business for additional disclosures related to this asset sale and below for additional disclosures related to the claims.

Legal Proceedings: We are subject to various legal proceedings, claims, and litigation, either asserted or unasserted that arise in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect the resolution of these matters will have a material adverse effect on our business, financial position, results of operations, or cash flows. However, the results of these matters cannot be predicted with certainty. Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information. Should we fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, then the financial results of that particular reporting period could be materially affected.

a) Intellectual Property Lawsuits

We protect our proprietary technology by applying for patents where appropriate and, in other cases, by preserving the technology, related know-how and information as trade secrets. The success and competitive position of our product lines are impacted by our ability to obtain intellectual property protection for our research and development efforts. We have, from time to time, exchanged correspondence with third parties regarding the assertion of patent or other intellectual property rights in connection with certain of our products and processes.

b) Sumitomo Electric Industries Ltd. ("SEI")

On September 23, 2014, SEI, filed for arbitration against EMCORE, as required under the Master Purchase Agreement between the parties (the "MPA"). SEI seeks $40.0 million from EMCORE, relating to claims for quality issues, expenses related to subpoenas issued in litigation against a vendor and customers of SEI, a claim that EMCORE made fraudulent or negligent misrepresentations to SEI in the Master Purchase Agreement, and other breach of contract claims. We believe that the claims in this matter are without merit and we intend to defend ourselves vigorously against them. However, because the matter is in a preliminary stage, we cannot be certain as to its outcome, or that an adverse decision in such action will be reached and would have a material adverse effect on our business, financial condition, results of operation or cash flows. On November 14, 2014, EMCORE answered SEI’s complaint and asserted several legal defenses.

NOTE 13. Equity

Common Stock Repurchase

In April 2015, EMCORE's Board of Directors authorized the Company to repurchase $45.0 million of shares of its common stock. On May 15, 2015, we announced the commencement of a modified "Dutch auction" tender offer to purchase for cash shares of our common stock (the "Tender Offer"). On June 15, 2015, we completed the Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses. The repurchased shares of common stock were recorded to treasury stock. The Company incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock.

Equity Plans

We provide long-term incentives to eligible officers, directors, and employees in the form of equity-based awards. We maintain three equity incentive compensation plans, collectively described below as our Equity Plans:

• the 2000 Stock Option Plan (2000 Plan),

• the 2010 Equity Incentive Plan (2010 Equity Plan),

• the 2012 Equity Incentive Plan (2012 Equity Plan).

We issue new shares of common stock to satisfy awards issued under our Equity Plans.

21

Stock Options

Most of our stock options vest and become exercisable over a four to five year period and have a contractual life of 10 years. Certain stock options awarded are intended to qualify as incentive stock options pursuant to Section 422A of the Internal Revenue Code.

The following table summarizes stock option activity under the Equity Plans for the nine months ended June 30, 2015:

	Number of Shares		Weighted Average Exercise Price	Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value (*) (in thousands)
Outstanding as of September 30, 2014	1,431,190		$19.06
Granted	17,150		$5.68
Exercised	(225,736	)	$4.78		$	194
Forfeited	(9,077	)	$5.28
Expired	(297,499	)	$19.83
Outstanding as of June 30, 2015	916,028		$22.22	2.46	$	347
Exercisable as of June 30, 2015	891,351		$22.68	2.28	$	330
Vested and expected to vest as of June 30, 2015	911,032		$22.31	2.43	$	344

(*) Intrinsic value for stock options represents the “in-the-money” portion or the positive variance between a stock option's exercise price and the underlying stock price. For the nine months ended June 30, 2014, the intrinsic value of options exercised was $4,000.

As of June 30, 2015, there was approximately $0.2 million of unrecognized stock-based compensation expense, net of estimated forfeitures, related to non-vested stock options granted under the Equity Plans which is expected to be recognized over an estimated weighted average life of 3.8 years.

Valuation Assumptions

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option valuation model, adhering to the straight-line attribution approach using the following weighted-average assumptions, of which the expected term and stock price volatility rate are highly subjective:

	For the three months ended June 30,					For the nine months ended June 30,
	2015		2014			2015			2014
Black-Scholes weighted average assumptions:
Expected dividend rate	—	%	—		%	—		%	—		%
Expected stock price volatility rate	63.5	%	92.0		%	70.5		%	93.2		%
Risk-free interest rate	1.9	%	1.9		%	1.8		%	1.9		%
Expected term (in years)	6.0		6.0			6.0			6.0
Weighted average grant date fair value per share of stock options granted:	$3.59		$	3.21		$	3.57		$	3.61

Restricted Stock

Restricted stock units (RSUs) granted under the 2010 Equity Plan and 2012 Equity Plan typically vest over 3 years and are subject to forfeiture if employment terminates prior to the lapse of the restrictions. RSUs are not considered issued or outstanding common stock until they vest.

22

The following table summarizes the activity related to RSUs for the nine months ended June 30, 2015:

Restricted Stock Activity	Restricted Stock Units
	Number of Shares		Weighted Average Grant Date Fair Value
Non-vested as of September 30, 2014	966,579		$4.71
Granted	524,150		$5.38
Vested	(841,609	)	$4.69
Forfeited	(41,949	)	$4.86
Non-vested as of June 30, 2015	607,171		$5.23

As of June 30, 2015, there was approximately $2.5 million of remaining unamortized stock-based compensation expense, net of estimated forfeitures, associated with RSUs, which will be expensed over a weighted average remaining service period of approximately 2.3 years. The 0.6 million outstanding non-vested RSUs have an aggregate intrinsic value of approximately $3.7 million and a weighted average remaining contractual term of 1.4 years. For the nine months ended June 30, 2015 and 2014, the intrinsic value of RSUs vested was $4.4 million and $1.7 million, respectively. Of the 0.6 million outstanding non-vested RSUs, approximately 0.6 million are expected to vest and have an aggregate intrinsic value of approximately $3.4 million and a weighted average remaining contractual term of 1.4 years. For the nine months ended June 30, 2014, the weighted average grant date fair value of RSUs granted was $4.89.

On December 10, 2014, in connection with the sale of the Photovoltaics Business and the change in control, 0.3 million RSU's vested.

Our actual results could differ materially from those discussed in the forward-looking statements. See Cautionary Statement Regarding Forward-Looking Statements.

Business Overview

EMCORE Corporation and its subsidiaries (referred to herein as the “Company”, “we”, “our”, or “EMCORE”) offers a broad portfolio of compound semiconductor-based products for the fiber optics market. We were established in 1984 as a New Jersey corporation and we have one reporting segment: Fiber Optics. EMCORE's Fiber Optics business provides optical components, subsystems and systems for high-speed telecommunications, Cable Television (CATV), Wireless and Fiber-To-The-Premises (FTTP) networks, as well as products for satellite communications, video transport and specialty photonics technologies for defense and homeland security applications.

Recent Developments

Sale of Photovoltaics Business

On September 17, 2014, EMCORE entered into an Asset Purchase Agreement (the “Photovoltaics Agreement”) with SolAero Acquisition Corporation ("SolAero"), a Delaware corporation and an affiliate of private equity firm Veritas Capital, pursuant to which SolAero agreed to acquire substantially all of the assets, and assume substantially all of the liabilities, primarily related to or used in connection with the Company’s photovoltaics business, including EMCORE's subsidiaries EMCORE Solar Power, Inc. and EMCORE IRB Company, LLC (collectively, the "Photovoltaics Business" and, the sale of the Photovoltaics Business and the "Photovoltaics Asset Sale") for $150.0 million in cash, prior to a $0.1 million to a working capital adjustment pursuant to the Photovoltaics Agreement finalized and paid by EMCORE during the quarter ended June 30, 2015. On December 10, 2014, EMCORE completed the Photovoltaics Asset Sale.

As a result the financial results of the Photovoltaics Business are presented as "discontinued operations" on the condensed consolidated statements of operations for the three and nine months ended June 30, 2015 and 2014; and the assets and liabilities of the Photovoltaics Business are presented as "assets of discontinued operations" and "liabilities of discontinued operations" on the condensed consolidated balance sheet as of September 30, 2014. No Photovoltaics assets and liabilities remain on the condensed consolidated balance sheet as of June 30, 2015. As of June 30, 2015, the Company has one remaining reportable segment: Fiber Optics. See Note 3 - Discontinued Operations in the notes to the condensed consolidated financial statements for more information.

Sale of Digital Products Business

On October 22, 2014, EMCORE entered into an Asset Purchase Agreement (the "Digital Products Agreement") with NeoPhotonics Corporation, a Delaware corporation ("NeoPhotonics") pursuant to which the Company agreed to sell certain assets, and transfer certain liabilities of the Company's telecommunications business (collectively, the "Digital Products Business" and, the sale of the Digital Products Business and the "Digital Products Assets Sale") to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain purchase price adjustments, consisting of $1.5 million in cash at closing and a promissory note in the principal amount of $16.0 million (the "Promissory Note"). The Promissory Note provided that it would bear interest of 5.0% per annum for the first year and 13.0% per annum for the second year, payable semi-annually in cash, and would mature two years from the closing of the transaction. In addition, the Promissory Note is subject to prepayments under certain circumstances, and is secured by certain of the assets sold to NeoPhotonics in the transaction.

On January 2, 2015, EMCORE and NeoPhotonics entered into Amendment No. 1 (the "APA Amendment") to the Digital Products Agreement. Among other things, the APA Amendment revised the nature and timing of the financial deliverable requirements of the Company to NeoPhotonics under the original Digital Products Agreement. The assets sold pursuant to the Digital Products Agreement included certain fixed assets, inventory and intellectual property for the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business. On January 2, 2015, EMCORE completed the sale of the Digital Products Business. On April 16, 2015, EMCORE and NeoPhotonics entered into an agreement to adjust the purchase price resulting in an adjusted balance of the Promissory Note of $15.5 million. On April 17, 2015, NeoPhotonics prepaid the balance outstanding of the promissory Note of $15.5 million, plus accrued interest of $0.2 million.

As the result of this transaction, the financial results of the Digital Products Business are presented as "discontinued operations" on the Condensed Consolidated Statements of Operations for the three months and nine ended June 30, 2015 and 2014; and the assets and liabilities of the Digital Products Business are presented as "assets of discontinued operations" and "liabilities of discontinued operations" on the Condensed Consolidated Balance Sheets as of September 30, 2014. No Digital Products assets and liabilities remain on the condensed consolidated balance sheet as of June 30, 2015. See Note 3 - Discontinued Operations in the notes to the condensed consolidated financial statements for more information.

We used a portion of the proceeds from the Photovoltaics Asset Sale and the Digital Products Asset Sale to pay for transaction costs associated with the asset sales, make payments required pursuant to existing retention award agreements, repay certain indebtedness and for general working capital purposes. We also used a portion of the proceeds from the Photovoltaics Asset Sale and the Digital Products Asset Sale to fund the Tender Offer (described below). The remaining proceeds from the asset sales may be used, at the discretion of our Board, provide liquidity to the Company's shareholders through one or more special dividends or repurchase of outstanding shares of the Company's common stock, invest in our other businesses, pursue other strategic opportunities or a combination thereof.

Common Stock Repurchase

In April 2015, the Company’s Board of Directors authorized the repurchase of $45.0 million of the outstanding shares of our common stock. On May 15, 2015, we announced the commencement of a modified "Dutch auction" tender offer to purchase for cash shares of our common stock (the "Tender Offer"). On June 15, 2015, we completed the Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses. Repurchased common stock was recorded to treasury stock. The Company incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock.

Strategy Committee of the Board of Directors

The Company’s Board of Directors created a Strategy Committee of the Board of Directors in December 2013, which is charged with evaluating strategic opportunities for the Company that may enhance shareholder value. The Strategy Committee may from time to time consider strategic opportunities to enhance shareholder value, which may include acquisitions, investments in joint ventures, partnerships, and other strategic alternatives, such as dispositions, reorganizations, recapitalizations or other similar transactions and may engage financial and other advisors to assist it in doing so. There is no assurance that the Strategy Committee will identify further strategic opportunities that the Company will determine to pursue, or that the consideration of any such opportunity would result in the completion of a strategic transaction.

Revenue

EMCORE's Fiber Optics business provides chip level devices, optical components, subsystems, and systems for high-speed telecommunications, CATV, and FTTP networks, as well as products for satellite communications, video transport, and specialty photonics technologies for defense and homeland security applications. Broadband products includes cable television products, fiber-to-the-premises products, satellite communication products, video transport products, and defense and homeland security products.

For the three months ended June 30, 2015, revenue increased 55.9% compared to the same period during the prior year driven by significantly higher sales of our CATV products primarily to U.S. customers and our chip level devices. Sales of our CATV products, which include our quadrature amplitude modulation (QAM) transmitters and receivers, represented the largest percentage of our total fiber optics-related revenue during the three-month period. Sales of our chip level device products, which include our avalanche photodiodes and gain chips, increased as EMCORE expanded sales to customers, primarily in Asia.

Gross Profit

Our cost of revenue consists of raw materials, compensation expense including non-cash stock-based compensation expense, depreciation expense and other manufacturing overhead costs, expenses associated with excess and obsolete inventories, and product warranty costs. Historically, cost of revenue as a percentage of revenue, which we refer to as our gross profit, has fluctuated significantly due to product mix, manufacturing yields and sales volumes, and inventory and specific product warranty charges.

Consolidated gross margins were 36.3% and 19.6% for the three months ended June 30, 2015 and 2014, respectively.

Stock-based compensation expense within cost of revenue totaled approximately $0.1 million and $0.1 million during the three months ended June 30, 2015 and 2014.

30

For the three months ended June 30, 2015, gross margins increased significantly when compared to the same period during the prior year. The increase in gross margins for the three months ended June 30, 2015 compared to the same period in 2014 was primarily due to higher sales volume and higher utilization of the manufacturing facility as we significantly increased production output resulting in higher levels of absorption. In addition, gross margins also increased from an improvement in product mix due to an increase in sales of our chip level device products, which typically have high margins.

Selling, General and Administrative (SG&A)

SG&A consists primarily of compensation expense including non-cash stock-based compensation expense related to executive, finance, and human resources personnel, as well as sales and marketing expenses, professional fees, amortization expense on intangible assets, legal and patent-related costs, and other corporate-related expenses.

Stock-based compensation expense within SG&A totaled approximately $0.2 million and $0.6 million during the three months ended June 30, 2015 and 2014.

SG&A expense for the three months ended June 30, 2015 was lower than the amount reported in the same period during the prior year primarily due tolower legal professional fees and compensation expense due to the reduction in the Company's size after the sale of the Photovoltaics and Digital Products Businesses.

As a percentage of revenue, SG&A expenses were 21.4% and 39.5% for the three months ended June 30, 2015 and 2014, respectively.

Research and Development (R&D)

R&D consists primarily of compensation expense including non-cash stock-based compensation expense, as well as engineering and prototype costs, depreciation expense, and other overhead expenses, as they related to the design, development, and testing of our products. Our R&D costs are expensed as incurred. We believe that in order to remain competitive, we must invest significant financial resources in developing new product features and enhancements and in maintaining customer satisfaction worldwide.

Stock-based compensation expense within R&D totaled $0.1 million and $0.1 million during the three months ended June 30, 2015 and 2014, respectively.

R&D expense for the three months ended June 30, 2015 was lower than the amounts reported in the same period during the prior year primarily due to lower compensation costs attributed to lower headcount.

As a percentage of revenue, R&D expenses were 10.7% and 17.2% for the three months ended June 30, 2015 and 2014, respectively.

Operating Income (Loss)

Operating income (loss) represents revenue less the cost of revenue and direct operating expenses incurred. Operating income (loss) is a measure of profit and loss that executive management uses to assess performance and make decisions. As a percentage of revenue, our operating income (loss) was 4.2%, and (37.1)% for the three months ended June 30, 2015 and 2014, respectively.

31

Other Income (Expense)

Foreign Exchange

Gains and losses from foreign currency transactions denominated in currencies other than the U.S. dollar, both realized and unrealized, are recorded as foreign exchange gain (loss) on our consolidated statements of operations and comprehensive income (loss). A majority of the gains or losses recorded relate to the change in value of the yuan renminbi relative to the U.S. dollar. The assets and liabilities of our foreign operations are translated from their respective functional currencies into U.S. dollars at the rates in effect at the consolidated balance sheet dates, and the revenue and expense amounts are translated at the average rate during the applicable periods reflected on the consolidated statements of operations and comprehensive income (loss). Foreign currency translation adjustments are recorded as accumulated other comprehensive income.

Change in Fair Value of Financial Instruments

As of September 30, 2014, warrants representing the right to purchase 400,001 shares, of our common stock were outstanding. The warrants expired on April 1, 2015.

Income Tax Expense

For the three months ended June 30, 2015, the Company reported $0.5 million of income tax expense from income from continuing operations and $1.6 million of income tax benefit within income from discontinued operations.

For the three months ended June 30, 2014, the Company reported $0.7 million of income tax benefit from losses from continuing operations and $0.7 million of income tax expense within income from discontinued operations.

Gain from Change in Estimate on ARO Obligation

As a result of the revision in the estimated amount and timing of cash flows for asset retirement obligations during the nine months ended June 30, 2015, the Company reduced asset retirement obligations liability by $2.9 million with an offsetting reduction to property, plant, and equipment of $2.1 million, and recorded a gain from change in estimate on ARO obligation of $0.8 million. The Company first reduced the net leasehold improvement asset to the extent of the carrying amount of the related asset initially recorded when the asset retirement obligations were established. The amount of the remaining reduction to the asset retirement obligations were recorded as a reduction to operating expenses. See Note 12 - Commitments and Contingencies in the notes to the condensed consolidated financial statements for additional information.

Operating loss represents revenue less the cost of revenue and direct operating expenses incurred. Operating loss is a measure of profit and loss that executive management uses to assess performance and make decisions. As a percentage of revenue, our operating loss was (9.8)%, and (34.5)% for the nine months ended June 30, 2015 and 2014, respectively.

34

Other Income (Expense)

Interest income (expense), net

During the nine months ended June 30, 2015, we recorded $0.2 million of interest income earned on the Promissory Note from NeoPhotonics which was primarily offset by an equivalent amount of interest expense incurred on the outstanding credit facility. See Note 3 - Discontinued Operations in the notes to the condensed consolidated financial statements for additional information.

Gain on Sale of Investment

During the nine months ended June 30, 2014, we sold our investment in a company that had a net book value of $0 at September 30, 2013, for $0.3 million.

Income Tax Expense

At September 30, 2014, the Company determined that it was more likely than not that certain deferred tax assets would be realized upon the sale of the Photovoltaic Business in fiscal year 2015. As a result, a net deferred tax valuation allowance release of $24.1 million was recorded as an income tax benefit during fiscal year 2014. The sale of the Photovoltaic Business closed on December 10, 2014 and the Company realized a gain on the transaction.

For the nine months ended June 30, 2015, the Company reported $1.9 million of income tax benefit from losses from continuing operations and $26.5 million of income tax expense within income from discontinued operations. The income tax expense within discontinued operations includes estimated alternative minimum tax and other adjustments prescribed by ASC 740 in allocating expected annual income tax expense (benefit) between continuing operations and discontinued operations. During the nine months ended June 30, 2015, the Company utilized $24.1 million of deferred tax assets. The Company expects to make a payment for alternative minimum taxes and the remaining income tax expense will be offset mainly through utilization of net operating loss carry forwards.

For the nine months ended June 30, 2014, the Company reported $1.4 million of income tax benefit from losses from continuing operations and $1.4 million of income tax expense within income from discontinued operations. Also see Note 11. Income and other Taxes in the notes to the condensed consolidated financial statements for more information.

During the nine months ended June 30, 2015, we recognized a gain of $87.0 million and $2.0 million, on the sales of the Photovoltaics Business and Digital Products Business, respectively, which is recorded within income from discontinued operations under the caption "gain on sale of discontinued operations". During the nine months ended June 30, 2015, we recorded income from discontinued operations from the Photovoltaics Business and Digital Products Business of $61.2 million and $4.0 million, net of tax, respectively. During the nine months ended June 30, 2014, we recorded income (loss) from discontinued operations from the Photovoltaics Business and Digital Products Business of $7.9 million and $(5.6) million, respectively.

35

During the first quarter of fiscal 2015, in connection with the liquidation of our Netherlands and Spain subsidiaries, we recognized other income within discontinued operations of $0.7 million previously recorded in accumulated other comprehensive income.

Order Backlog

EMCORE'S product sales are made pursuant to purchase orders, often with short lead times. These orders are subject to revision or cancellation and often are made without deposits. Products typically ship within the same quarter in which a purchase order is received; therefore, our order backlog at any particular date is not necessarily indicative of actual revenue or the level of orders for any succeeding period.

Liquidity and Capital Resources

Historically, we have consumed cash from operations and incurred significant net losses. We have managed our liquidity position through the sale of assets, a series of cost reduction initiatives, borrowings from our credit facility, and capital markets transactions.

On June 15, 2015, we completed the previously announced Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses. Repurchased common stock was recorded to treasury stock. We incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock.

As of June 30, 2015, cash and cash equivalents totaled $114.1 million and net working capital totaled approximately $126.4 million. Net working capital, calculated as current assets minus current liabilities, is a financial metric we use which represents available operating liquidity. For the nine months ended June 30, 2015, we earned net income of $61.6 million.

During the nine months ended June 30, 2015, the following changes to our liquidity occurred:

• Sale of Photovoltaics Business: On December 10, 2014, we completed the sale of our Photovoltaics Business for$150.0 million in cash, prior to working capital adjustments of $0.1 million recorded in the quarter ended June 30, 2015. These proceeds will provide us with working capital for fiscal year 2015 and beyond.

• Sale of Digital Products Business: On January 2, 2015, we completed the sale of our Digital Products Business for $1.5 million in cash and an adjusted Promissory Note balance of $15.5 million. On April 17, 2015, NeoPhotonics prepaid the outstanding balance of the Promissory Note, including accrued interest, in the amount of $15.7 million.

• Credit Facility: On November 11, 2010, we entered into a Credit and Security Agreement (credit facility) with Wells Fargo Bank, National Association ("Wells Fargo"). The credit facility, as it has been amended through its sixth amendment, currently provides us with a revolving credit of up to $15.0 million through November 2015 that can be used for working capital requirements, letters of credit, and other general corporate purposes. The credit facility is secured by the Company's assets and is subject to a borrowing base formula based on the Company's eligible accounts receivable, inventory, and machinery and equipment accounts.

On December 3, 2014, we entered into a Sixth Amendment to the credit facility, pursuant to which Wells Fargo agreed, to automatically release all encumbrances covering certain of the Company’s assets to be sold pursuant to the Photovoltaics Agreement and the Digital Products Agreement. In addition, on December 10, 2014 upon notice to Wells Fargo of the closing of the transaction contemplated by the Photovoltaics Agreement, the maximum borrowing allowed under the credit facility was reduced from $35.0 million to $15.0 million, and certain other changes to the borrowing base calculations went into effect. As of June 30, 2015, there were no amounts outstanding under the credit facility and the Company was in compliance with all financial covenants.

We believe that our existing balances of cash and cash equivalents and amounts expected to be available under our credit facility will provide us with sufficient financial resources to meet our cash requirements for operations, working capital, and capital expenditures for the next twelve months. At the discretion of our Board, we may use our existing balances of cash and cash equivalents to provide liquidity to our shareholders through one or more special dividends or the repurchase of additional shares of our outstanding common stock, make investments in our other businesses, pursue other strategic opportunities or a combination thereof.

For the nine months ended June 30, 2015, our operating activities consumed cash of $2.1 million primarily due to the effect of adjustments for non-cash charges, including the gain on sale of the Photovoltaics Business of $87.0 million, the gain on sale of the Digital Products Business of $2.0 million, and the gain from change in estimate on ARO obligation of $0.8 million, foreign currency translation adjustment of $0.7 million as well as the changes in our current assets and liabilities (or working capital components) of $4.7 million, partially offset by deferred income taxes of $24.1 million, stock-based compensation expense of $4.1 million, warranty provision of $0.7 million, depreciation, amortization and accretion expense of $2.3 million, allowance for doubtful accounts of $0.5 million, and our net income of $61.6 million. The change in our current assets and liabilities was primarily the result of an increase in inventory of $3.0 million, other assets of $0.5 million, a decrease in accounts payable of $3.0 million, a decrease in accrued expenses and other liabilities of $5.0 million, partially offset by a decrease in accounts receivable of $6.8 million.

Fiscal 2014:

For the nine months ended June 30, 2014, our operating activities provided cash of $3.6 million primarily due to the changes in our current assets and liabilities (or working capital components) of $2.7 million, depreciation, amortization and accretion expense of $6.3 million, stock-based compensation expense of $3.4 million, warranty provision of $1.9 million and allowance for doubtful accounts of $0.2 million partially offset by our net loss of $10.6 million and the gain on sale of investment of $0.3 million. The change in our current assets and liabilities was primarily the result of a decrease in inventory of $4.0 million, other assets of $2.1 million and an increase in accounts payable of $1.5 million, partially offset by a decrease in accrued expenses and other liabilities of $3.3 million and an increase in accounts receivable of $1.6 million.

Working Capital Components:

Accounts Receivable: We generally expect the level of accounts receivable at any given quarter to reflect the level of sales in that quarter. Our accounts receivable balances have fluctuated historically due to the timing of account collections, timing of product shipments, and/or change in customer credit terms.

Inventory: We generally expect the level of inventory at any given quarter to reflect the change in our expectations of forecasted sales. Our inventory balances have fluctuated historically due to the timing of customer orders and product shipments, changes in our internal forecasts related to customer demand, as well as adjustments related to excess and obsolete inventory.

Accounts Payable: The fluctuation of our accounts payable balances is primarily driven by changes in inventory purchases as well as changes related to the timing of actual payments to vendors.

Accrued Expenses: Our largest accrued expense typically relates to compensation. Historically, fluctuations of our accrued expense accounts have primarily related to changes in the timing of actual compensation payments, adjustments to our warranty accrual, and accruals related to professional fees.

Contractual Obligations and Commitments

Our contractual obligations and commitments for the remainder of fiscal 2015 and over the next five fiscal years are summarized in the table below:

(in thousands)
	Total		2015		2016 to 2017		2018 to 2019		2020 and later
Purchase obligations	$	11,919	$	11,729	$	190	$	—	$	—
Asset retirement obligations	2,030		265		40		45		1,680
Operating lease obligations	1,665		270		1,395		—		—
Total contractual obligations and commitments	$	15,614	$	12,264	$	1,625	$	45	$	1,680

Interest payments are not included in the contractual obligations and commitments table above since they are insignificant to our consolidated results of operations.

The contractual obligations and commitments table above also excludes unrecognized tax benefits because we are unable to reasonably estimate the period during which this obligation may be incurred, if at all. As of June 30, 2015, we had unrecognized tax benefits of $0.6 million.

Purchase Obligations

Our purchase obligations represent agreements to purchase goods or services that are enforceable and legally binding, that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transactions.

Asset Retirement Obligations

We have known conditional asset retirement conditions, such as certain asset decommissioning and restoration of rented facilities to be performed in the future. Our asset retirement obligations include assumptions related to renewal option periods where we expect to extend facility lease terms. Revisions in estimated liabilities can result from revisions of estimated inflation rates, escalating retirement costs, and changes in the estimated timing of settling asset retirement obligations. See Note 12- Commitments and Contingencies in the notes to the condensed consolidated financial statements for additional information related to our asset retirement obligations.

Operating Leases

Operating leases include non-cancelable terms and exclude renewal option periods, property taxes, insurance and maintenance expenses on leased properties. There are no off-balance sheet arrangements other than our operating leases. See Note 12- Commitments and Contingencies in the notes to the condensed consolidated financial statements for additional information related to our operating lease obligations.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements other than our operating leases described above.

Geographical Information

See Note 14- Geographic Information in the notes to the condensed consolidated financial statements for disclosures related to revenue, geographic revenue and significant customers.

Recent Accounting Pronouncements

See Note 2 - Recent Accounting Pronouncements in the notes to the condensed consolidated financial statements for disclosures related to recent accounting pronouncements.

Restructuring Accruals

See Note 9 - Accrued Expenses and Other Current Liabilities in the notes to the condensed consolidated financial statements for disclosures related to our severance and restructuring-related accrual accounts.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

39

For Quantitative and qualitative disclosures about market risk affecting the Company, see Item 7A - Quantitative and Qualitative Disclosures About Market Risk in our Annual Report on Form 10-K for the fiscal year ended September 30, 2014. We do not believe the Company's exposure to market risk has changed materially since September 30, 2014.

40

ITEM 4. Controls and Procedures

a.    Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Securities Exchange Act of 1934 (the “Act”) is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to management, including its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial and Accounting Officer), as appropriate, to allow timely decisions regarding required disclosure.

Management, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) promulgated under the Act) as of the end of the period covered by this report. Based upon this evaluation, management concluded that as of June 30, 2015, the Company's disclosure controls and procedures were not effective because of the material weaknesses described in section (c).

Attached as exhibits to this Quarterly Report on Form 10-Q are certifications of the Company's Chief Executive Officer and Chief Financial Officer, which are required in accordance with Rule 13a-14 of the Act. This Evaluation of Disclosure Controls and Procedures section includes information concerning management's evaluation of disclosure controls and procedures referred to in those certifications and, as such, should be read in conjunction with the certifications of the Company's Chief Executive Officer and Chief Financial Officer.

b.     Changes in Internal Control over Financial Reporting

There were no changes in the Company's internal control over financial reporting during the quarter ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting except as discussed below.

In light of the material weaknesses described in section (c) below, additional analyses and other procedures were performed to ensure that the Company's condensed consolidated financial statements included in this Quarterly Report on Form 10-Q were prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”).  These measures included expanded quarter-end tax analysis and tax provision procedures and management's own internal reviews and efforts to remediate the material weakness in internal control over financial reporting described below.  As a result of these measures, management concluded that the Company's consolidated financial statements included in this Quarterly Report on Form 10-Q present fairly, in all material respects, the Company's consolidated financial position, results of operations, and cash flows as of the dates, and for the periods presented, in conformity with GAAP.

c.    In Process Remediation Actions to Address the Internal Control Weaknesses

A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Under the supervision of our Chief Executive Officer and Chief Financial Officer and with the participation of our management, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of September 30, 2014 based on the framework in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on the criteria established by COSO, management identified a material weakness in the Company's internal control over financial reporting as of September 30, 2014 which continues to exist as of June 30, 2015. The Company did not design and maintain an effective review control over accounting for the deferred tax valuation allowance, specifically considering all available evidence associated with significant and unusual transactions through the issuance of the financial statements.

41

In response to the identified material weakness described above, management has dedicated resources to improving its control environment and initiated a remediation plan which included the following actions:

• Processes, procedures and controls over accounting for the deferred tax valuation allowance are being reviewed and modified to ensure greater oversight and evaluation of income tax matters through the issuance of the financial statements.

• Additional external resources have been, and will continue to be engaged as necessary to ensure that all concepts and interpretations around income tax accounting have been appropriately considered.

Management believes that actions taken during the quarter ended June 30, 2015, along with other improvements not yet implemented, will address the material weaknesses in the Company's internal control over financial reporting described above.

Management intends to continue to monitor the effectiveness of these actions and will make changes to the action plan if deemed necessary and appropriate.

d.     Limitations on the Effectiveness of Internal Control over Financial Reporting

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls or our internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by individual acts, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based, in part, upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with associated policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

42

PART II.    Other Information

ITEM 1.     Legal Proceedings

See Note 12- Commitments and Contingencies in the notes to our condensed consolidated financial statements for disclosures related to our legal proceedings.

ITEM 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A. "Risk Factors" in our Annual Report on Form 10-K for the year ended September 30, 2014, which could materially affect our business, financial condition or future results. We do not believe the Company's risks have changed materially since we filed our Form 10-K on December 12, 2014. The risks described in our Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem immaterial also may materially adversely affect our business, financial condition and/or operating results.

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

Not Applicable.

Issuer Purchases of Equity Securities

The following table sets forth information with respect to purchases of common stock made during the quarter ended June 30, 2015.

Period	Total Number of Shares Purchased	Average Price Paid per Share (2)		Total Number of Shares Purchased as Part of Publicly Announced Plans	Increase in Dollars for Share Repurchase Authorization (1)
April 1, 2015 through April 30, 2015	—	$	—	—	$	—

Total	6,870,229	$	6.55	6,870,229	$	45,000,000

(1) In April 2015, EMCORE's Board of Directors authorized the Company to repurchase $45.0 million of shares of its common stock. On May 15, 2015, we announced the commencement of a modified "Dutch auction" tender offer to purchase for cash shares of our common stock (the "Tender Offer"). On June 15, 2015, we completed the Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses.

(2) The purchase price for the 6.9 million shares repurchased in the Tender Offer that commenced on May 15, 2015, was $6.55 per share. The Company incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock, resulting in an effective aggregate purchase price of approximately $6.64 per share.

Fair Value Disclosures [Abstract]

Fair Value Accounting

Fair Value Accounting

ASC 820, Fair Value Measurements, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

• Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument.

• Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value.

A financial asset or liability's classification within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The following table lists our financial assets and liabilities that are measured at fair value on a recurring basis:

Fair Value Measurement
(in thousands)	Level 1		Level 2	Level 3
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Remaining Inputs	Significant Unobservable Inputs	Total
As of June 30, 2015
Assets:
Cash and cash equivalents	$	114,129	—	—	$	114,129
Restricted cash	26		—	—	26
Liabilities:
Warrant liability	—		—	—	—
As of September 30, 2014
Assets:
Cash and cash equivalents	$	20,687	—	—	$	20,687
Restricted cash	1,482		—	—	1,482
Liabilities:
Warrant liability	—		122	—	122

Cash consists primarily of bank deposits or, occasionally, highly liquid short-term investments with a maturity of three months or less at the time of purchase.

Restricted cash represents temporarily restricted deposits held as compensating balances against short-term borrowing arrangements.

As of September 30, 2014, warrants representing the right to purchase 400,001 shares, of our common stock were outstanding. The warrants expired on April 1, 2015. All of our warrants met the classification requirements for liability accounting pursuant to ASC 815, Derivatives and Hedging. Historically, recording the change in the fair value of our warrants impacted our statements of operations and comprehensive income (loss) and was primarily due to the change in the closing price of our common stock.

The carrying amounts of accounts receivable, prepaid expenses and other current assets, borrowings from our credit facility, accounts payable, accrued expenses and other current liabilities approximate fair value because of the short maturity of these instruments.

On September 17, 2014, EMCORE entered into the Photovoltaics Agreement with SolAero pursuant to which the Company agreed to sell the Photovoltaics Business for $150.0 million in cash, subject to a working capital adjustment. On December 10, 2014, EMCORE completed the Photovoltaics Asset Sale.

The financial results of the Photovoltaics Business are reported as discontinued operations for the three and nine months ended June 30,2015 and 2014, respectively. In connection with this transaction, we sold net assets of $60.3 million to SolAero and incurred transaction costs of $2.7 million. During the three months ended December 31, 2014, we recognized a gain of $56.8 million, net of tax on the sale of the Photovoltaics Business which is recorded within discontinued operations in the condensed consolidated statements of operations and comprehensive income (loss). During the three months ended June 30, 2015, we made a payment of $0.1 million to SolAero to complete the working capital adjustment under the agreement. During the three and nine months ended June 30, 2015, we recognized gains of $0.2 million and $0.4 million, respectively, associated with the settlement of outstanding obligations on retained Photovoltaic product warranties.

We have classified the assets and liabilities that were sold as "assets of discontinued operations" and "liabilities of discontinued operations" within current and non-current assets and liabilities, respectively, on the condensed consolidated balance sheet as of September 30, 2014. As of September 30, 2014, the carrying amount of goodwill related to the Photovoltaics Business was $20.4 million and this balance was reclassified to non-current assets of discontinued operations.

Sale of Digital Products Business

On October 22, 2014, EMCORE entered into the Digital Products Agreement with NeoPhotonics pursuant to which the Company agreed to sell certain assets, and transfer certain liabilities of the Company's Digital Products Business to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain purchase price adjustments, consisting of $1.5 million in cash at closing and a promissory note in the principal amount of $16.0 million (the "Promissory Note"). The Promissory Note provided that it would bear interest of 5.0% per annum for the first year and 13.0% per annum for the second year, payable semi-annually in cash, and would mature two years from the closing of the transaction. In addition, the Promissory Note was subject to prepayments under certain circumstances, and is secured by certain of the assets sold to NeoPhotonics in the transaction.

On January 2, 2015, EMCORE and NeoPhotonics entered into the APA Amendment. Among other things, the APA Amendment revised the nature and timing of the financial deliverable requirements of the Company to NeoPhotonics under the original Digital Products Agreement. The assets sold pursuant to the Digital Products Agreement included certain fixed assets, inventory and intellectual property for the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business. On January 2, 2015, EMCORE completed the sale of the Digital Products Business. On April 16, 2015, EMCORE and NeoPhotonics entered into an agreement to adjust the purchase price resulting in an adjusted balance of the Promissory Note of $15.5 million. On April 17, 2015, NeoPhotonics prepaid the outstanding balance of the Promissory Note of $15.5 million, plus accrued interest of $0.2 million.

The financial results of the Digital Products Business are reported as discontinued operations for the three and nine months ended June 30, 2015 and 2014. In connection with this transaction, we sold net assets of $13.3 million to NeoPhotonics and incurred transaction costs of $1.6 million. During the nine months ended June 30, 2015, we recognized a gain of $2.0 million on the sale of the Digital Products Business which is recorded within discontinued operations in the condensed consolidated statements of operations and comprehensive income (loss).

Description of Business

Business Overview

EMCORE Corporation and its subsidiaries (referred to herein as the “Company”, “we”, “our”, or “EMCORE”) offers a broad portfolio of compound semiconductor-based products for the fiber optics market. We were established in 1984 as a New Jersey corporation and we have one reporting segment: Fiber Optics. EMCORE's Fiber Optics business provides optical components, subsystems and systems for high-speed telecommunications, Cable Television (CATV), Wireless and Fiber-To-The-Premises (FTTP) networks, as well as products for satellite communications, video transport and specialty photonics technologies for defense and homeland security applications. EMCORE's Solar Photovoltaics business, which was sold in December 2014, provided products for space power applications including high-efficiency multi-junction solar cells, Covered Interconnect Cells (CICs) and complete satellite solar panels. EMCORE sold certain assets, and transferred certain liabilities, of the Company's telecommunications business, including the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business, in January 2015. In addition to organic growth and development of our existing Fiber Optics market, we intend to pursue other strategies to enhance shareholder value, which may include acquisitions, investments in joint ventures, partnerships, and other strategic alternatives, such as dispositions, reorganizations, recapitalizations or other similar transactions. Accordingly, the Strategy Committee of the Board and our management may from time to time be engaged in evaluating potential strategic opportunities and may enter into definitive agreements with respect to such transactions or other strategic alternatives.

Basis of Presentation

On September 17, 2014, EMCORE entered into an Asset Purchase Agreement (the “Photovoltaics Agreement”) with SolAero Technologies Corporation ("SolAero") (formerly known as Photon Acquisition Corporation) pursuant to which the Company agreed to sell substantially all of the assets, and assume substantially all of the liabilities, primarily related to or used in connection with the Company’s photovoltaics business, including EMCORE's subsidiaries EMCORE Solar Power, Inc. and EMCORE IRB Company, LLC (collectively, the "Photovoltaics Business" and, the sale of the Photovoltaics Business, the "Photovoltaics Asset Sale") to SolAero for $150.0 million in cash, prior to a $0.1 million working capital adjustment pursuant to the Photovoltaics Agreement finalized and paid by EMCORE during the quarter ended June 30, 2015. On December 10, 2014, EMCORE completed the Photovoltaics Asset Sale.

On October 22, 2014, EMCORE entered into an Asset Purchase Agreement (the "Digital Products Agreement") with NeoPhotonics Corporation, a Delaware corporation ("NeoPhotonics"), pursuant to which the Company agreed to sell certain assets, and transfer certain liabilities, of the Company's telecommunications business (collectively, the "Digital Products Business" and, the sale of the Digital Products Business, the "Digital Products Assets Sale") to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain adjustments, consisting of $1.5 million in cash at closing and a promissory note in the principal amount of $16.0 million (the "Promissory Note").

On January 2, 2015, EMCORE and NeoPhotonics entered into Amendment No. 1 (the "APA Amendment") to the Digital Products Agreement dated October 22, 2014. Among other things, the APA Amendment revised the nature and timing of the financial deliverable requirements of the Company to NeoPhotonics under the original Digital Products Agreement. The assets sold pursuant to the Digital Products Agreement included certain fixed assets, inventory and intellectual property for the ITLA, micro-ITLA, T-TOSA and T-XFP product lines within the Company’s telecommunications business. On January 2, 2015, EMCORE completed the sale of the Digital Products Business. On April 16, 2015, EMCORE and NeoPhotonics entered into an agreement to adjust the purchase price resulting in an adjusted balance of the Promissory Note of $15.5 million. On April 17, 2015, NeoPhotonics prepaid the entire outstanding balance of the Promissory Note of $15.5 million, plus accrued interest of $0.2 million.

The Photovoltaics Asset Sale and Digital Products Asset Sale are reported as discontinued operations, which require retrospective restatement of prior periods to classify the results of operations as discontinued operations. We have also reclassified the assets and liabilities that were sold within the descriptions "assets of discontinued operations" and "liabilities of discontinued operations" within current and non-current assets and liabilities, respectively, on the condensed consolidated balance sheet as of September 30, 2014. No Photovoltaics or Digital Products assets or liabilities remain on the condensed consolidated balance sheet as of June 30, 2015. The financial results of the Photovoltaics Business and the Digital Products Business are presented as "discontinued operations" on the condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended June 30, 2015 and 2014. See also Note 3 - Discontinued Operations. The notes to our condensed consolidated financial statements relate to our continuing operations only, unless otherwise indicated.

Beginning in the first quarter of fiscal year 2015, the Company operates as a single reportable segment.

Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information, and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and notes required by U.S. GAAP for annual financial statements. In our opinion, the interim financial statements reflect all normal adjustments that are necessary to provide a fair presentation of the financial results for the interim periods presented. Operating results for interim periods are not necessarily indicative of results that may be expected for an entire fiscal year. The condensed consolidated balance sheet as of September 30, 2014 has been derived from the audited consolidated financial statements as of such date as adjusted for discontinued operations. Also see Note 3 - Discontinued Operations. For a more complete understanding of our business, financial position, operating results, cash flows, risk factors and other matters, please refer to our Annual Report on Form 10-K for the fiscal year ended September 30, 2014.

All significant intercompany accounts and transactions have been eliminated in consolidation. We are not the primary beneficiary of, nor do we hold a significant variable interest in, any variable interest entity. We have evaluated subsequent events through the date that the financial statements were issued.

Sale of Fiber Optics-related Assets

On March 27, 2012, we entered into a Master Purchase Agreement with a subsidiary of Sumitomo Electric Industries, LTD (SEI), pursuant to which we agreed to sell certain assets and transfer certain obligations associated with our Fiber Optics segment. On May 7, 2012, we completed the sale of these assets to SEI and recorded a gain of approximately $2.8 million. Under the terms of the Master Purchase Agreement, we have agreed to indemnify SEI for up to $3.4 million of potential claims and expenses for the two-year period following the sale and we have recorded this amount as a deferred gain on our balance sheet as of June 30, 2015 and September 30, 2014 as a result of these contingencies. SEI paid $13.1 million in cash and deposited approximately $2.6 million into escrow as security for indemnification obligations and any purchase price adjustments. During the fiscal year ended September 30, 2013, we resolved the purchase price contingencies resulting in the reduction of the purchase price by $1.1 million. The reduced purchase price is recorded as an offset to the escrow receivable of $2.6 million. There remains a deferred gain of $3.4 million related to our indemnification obligation to SEI and an escrow receivable of $1.5 million as of June 30, 2015 as claims have been made under the Master Purchase Agreement against these balances prior to the end of the indemnification period in May 2014. We are not able to determine at this time the outcome of any potential settlements associated with the remaining claims and as a result have not recorded any related adjustments to the deferred gain amount.

Liquidity and Capital Resources

Historically, we have consumed cash from operations and incurred significant net losses. We have managed our liquidity position through a series of cost reduction initiatives, borrowings from our credit facility, capital markets transactions, and the sale of assets.

As of June 30, 2015, cash and cash equivalents totaled $114.1 million and net working capital totaled approximately $126.4 million. Net working capital, calculated as current assets minus current liabilities, is a financial metric we use which represents available operating liquidity. For the nine months ended June 30, 2015, we earned net income of $61.6 million.

In April 2015, EMCORE's Board of Directors authorized the Company to repurchase $45.0 million of its common stock. On May 15, 2015, we announced the commencement of a modified "Dutch auction" tender offer to purchase for cash shares of our common stock (the "Tender Offer"). On June 15, 2015, we completed the Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses. Repurchased common stock were recorded to treasury stock. The Company incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock.

With respect to measures taken to improve liquidity:

• Sale of Photovoltaics Business: On December 10, 2014, we completed the sale of our Photovoltaics Business for$150.0 million in cash prior to working capital adjustments of $0.1 million. These proceeds will provide us with working capital for fiscal year 2015 and beyond.

• Sale of Digital Products Business: On January 2, 2015, we completed the sale of our Digital Products Business for $1.5 million in cash and an adjusted Promissory Note balance of $15.5 million. On April 17, 2015, NeoPhotonics paid in full the outstanding balance of the Promissory Note of $15.5 million, plus accrued interest of $0.2 million.

• Credit Facility: On November 11, 2010, we entered into a Credit and Security Agreement (credit facility) with Wells Fargo Bank, National Association ("Wells Fargo"). The credit facility, as it has been amended through its sixth amendment, currently provides us with a revolving credit of up to $15.0 million through November 2015 that can be used for working capital requirements, letters of credit, and other general corporate purposes. The credit facility is secured by the Company's assets and is subject to a borrowing base formula based on the Company's eligible accounts receivable, inventory, and machinery and equipment accounts.

On December 3, 2014, we entered into a Sixth Amendment to the credit facility, pursuant to which Wells Fargo agreed, to automatically release all encumbrances covering certain of the Company’s assets to be sold pursuant to the Photovoltaics Agreement and the Digital Products Agreement. In addition, on December 10, 2014 upon notice to Wells Fargo of the closing of the transaction contemplated by the Photovoltaics Agreement, the maximum borrowing allowed under the credit facility was reduced from $35.0 million to $15.0 million, and certain other changes to the borrowing base calculations went into effect.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements that are of significance, or of potential significance, to us other than those discussed below:

• In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This standard changes the criteria for reporting discontinued operations. Under the accounting standard update, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity's operations and financial results when either it qualifies as held for sale, disposed of by sale, or disposed of other than by sale. In addition, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. While early adoption is allowed, we have determined that we would not early adopt and as a result this accounting standard update will be effective for our fiscal year beginning on October 1, 2015. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

• In May 2014, as part of its ongoing efforts to assist in the convergence of U.S. GAAP and International Financial Reporting Standards, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Under the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. On July 9, 2015, the FASB voted to defer the effective date of implementation by one year. The new standard will be effective for us beginning October 1, 2018 and early adoption is permitted as of October 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We anticipate this standard will not have a material impact on our Condensed Consolidated Financial Statements.

• In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The standard provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. In addition, the standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The guidance is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. This accounting standard update will be effective for our fiscal year beginning October 1, 2017. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

• In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The standard simplifies the subsequent measurement of inventory. This standard requires inventory to be measured at the lower of cost and net realizable value and applies only to inventories for which cost is determined by methods other than last-in-first-out and the retail inventory method. Under this guidance, net realizable value is one of several calculations an entity needs to make to measure inventory at lower of cost or market. The guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. Early adoption is permitted. The new standard will be effective for our fiscal year beginning October 1, 2017. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Operating Lease Obligations: We lease certain land, facilities, and equipment under non-cancelable operating leases. Operating lease amounts exclude renewal option periods, property taxes, insurance, and maintenance expenses on leased properties. Our facility leases typically provide for rental adjustments for increases in base rent (up to specific limits), property taxes, insurance, and general property maintenance that would be recorded as rent expense. Rent expense was approximately $0.3 million and $0.5 million for the three months ended June 30, 2015 and 2014, respectively, and approximately $1.0 million and $1.3 million for the nine months ended June 30, 2015 and 2014, respectively. There are no off-balance sheet arrangements other than our operating leases.

Asset Retirement Obligations ("ARO"): We have known conditional asset retirement conditions, such as certain asset decommissioning and restoration of rented facilities to be performed in the future. Our asset retirement obligations include assumptions related to renewal option periods for those facilities where we expect to extend lease terms. The Company recognizes its estimate of the fair value of its asset retirement obligations in the period incurred in long-term liabilities. The fair value of the asset retirement obligations is also capitalized as property, plant and equipment.

In future periods, the asset retirement obligation is accreted for the change in its present value and capitalized costs are depreciated over the useful life of the related assets. If the fair value of the estimated asset retirement obligation changes, an adjustment will be recorded to both the asset retirement obligation and the asset retirement capitalized cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, changes in estimated retirement costs, and changes in the estimated timing of settling asset retirement obligations. The fair value of our asset retirement obligations were estimated by discounting projected cash flows over the estimated life of the related assets using credit adjusted risk-free rates which ranged from 3.25% to 5.78%. There were no asset retirement obligations settled during the three and nine months ended June 30, 2015, and 2014. Accretion expense of $22,000 and $43,000 was recorded during the three months ended June 30, 2015, and 2014, respectively. Accretion expense of $89,000 and $128,000 was recorded during the nine months ended June 30, 2015, and 2014, respectively.

EMCORE leases a major facility in Alhambra, California covering six buildings where manufacturing, research and development, and general and administrative work is provided. Several leases related to these facilities, which expired in 2011, were being maintained on a month-to-month basis. In November 2014, a new lease for four of the six buildings was signed which was retroactively effective on October 1, 2014. The new lease extended the terms of the lease for three years plus a three year option to extend the lease and clarified the obligations and restoration work necessary to restore the buildings back to the requirements in the lease.

The Company’s asset retirement obligation for the leased Alhambra facilities consists of legal requirements to return the existing leased facilities to prescribed state and certain environmental work to be performed due to the presence of a manufacturing fabrication operation and significant changes to the facilities over the past thirty years. EMCORE had estimated a significant asset retirement obligation associated with this site.

During the first quarter of fiscal 2015, the Company completed an analysis of the new Alhambra lease and revised its estimated future cash flows of its asset retirement obligations. The analysis required estimating the probability or likelihood that the Company will be required to remove certain infrastructure and restore the leased properties as set forth in the new lease, and the timing and amount of those future costs. The analysis resulted in the downward revision of the Company’s asset retirement obligation liability. This change in the estimated cash flows resulted in a reduction in the asset retirement obligations liability by $2.9 million with an offsetting reduction to property, plant, and equipment of $2.1 million, and a gain from change in estimate of ARO obligation of $0.8 million. The Company first reduced the net leasehold improvement asset to the extent of the carrying amount of the related asset initially recorded when the asset retirement obligations were established. The amount of the remaining reduction to the asset retirement obligations was recorded as a reduction to operating expenses.

The following table summarizes asset retirement obligations activity.

Indemnifications: We have agreed to indemnify certain customers against claims of infringement of the intellectual property rights of others in our sales contracts with these customers. Historically, we have not paid any claims under these indemnification obligations. On September 19, 2013, we received written notice from a customer of our broadband products requesting indemnification relating to a lawsuit brought against them alleging patent infringement of a system incorporating our product. As of June 30, 2015, there has been no resolution to this claim.

In March 2012, we entered into a Master Purchase Agreement with SEI, pursuant to which we agreed to sell certain assets and transfer certain obligations associated with our Fiber Optics segment. Under the terms of the Master Purchase Agreement, we have agreed to indemnify SEI for up to $3.4 million of potential claims and expenses for the two-year period following the sale and we recorded this amount as a deferred gain on our balance sheet as of June 30, 2015 and September 30, 2014 as a result of these contingencies. In April 2013, May 2013 and May 2014, we received letters from SEI asserting indemnification claims under the Master Purchase Agreement. As of June 30, 2015, there has been no resolution to these claims. See Note 1 - Description of Business for additional disclosures related to this asset sale and below for additional disclosures related to the claims.

Legal Proceedings: We are subject to various legal proceedings, claims, and litigation, either asserted or unasserted that arise in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect the resolution of these matters will have a material adverse effect on our business, financial position, results of operations, or cash flows. However, the results of these matters cannot be predicted with certainty. Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information. Should we fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, then the financial results of that particular reporting period could be materially affected.

a) Intellectual Property Lawsuits

We protect our proprietary technology by applying for patents where appropriate and, in other cases, by preserving the technology, related know-how and information as trade secrets. The success and competitive position of our product lines are impacted by our ability to obtain intellectual property protection for our research and development efforts. We have, from time to time, exchanged correspondence with third parties regarding the assertion of patent or other intellectual property rights in connection with certain of our products and processes.

b) Sumitomo Electric Industries Ltd. ("SEI")

On September 23, 2014, SEI, filed for arbitration against EMCORE, as required under the Master Purchase Agreement between the parties (the "MPA"). SEI seeks $40.0 million from EMCORE, relating to claims for quality issues, expenses related to subpoenas issued in litigation against a vendor and customers of SEI, a claim that EMCORE made fraudulent or negligent misrepresentations to SEI in the Master Purchase Agreement, and other breach of contract claims. We believe that the claims in this matter are without merit and we intend to defend ourselves vigorously against them. However, because the matter is in a preliminary stage, we cannot be certain as to its outcome, or that an adverse decision in such action will be reached and would have a material adverse effect on our business, financial condition, results of operation or cash flows. On November 14, 2014, EMCORE answered SEI’s complaint and asserted several legal defenses.

Equity

Common Stock Repurchase

In April 2015, EMCORE's Board of Directors authorized the Company to repurchase $45.0 million of shares of its common stock. On May 15, 2015, we announced the commencement of a modified "Dutch auction" tender offer to purchase for cash shares of our common stock (the "Tender Offer"). On June 15, 2015, we completed the Tender Offer and purchased 6.9 million shares of our common stock at a purchase price of $6.55 per share, for an aggregate cost of $45.0 million excluding fees and expenses. The repurchased shares of common stock were recorded to treasury stock. The Company incurred costs of $0.6 million in connection with the Tender Offer, which were recorded to treasury stock.

Equity Plans

We provide long-term incentives to eligible officers, directors, and employees in the form of equity-based awards. We maintain three equity incentive compensation plans, collectively described below as our Equity Plans:

• the 2000 Stock Option Plan (2000 Plan),

• the 2010 Equity Incentive Plan (2010 Equity Plan),

• the 2012 Equity Incentive Plan (2012 Equity Plan).

We issue new shares of common stock to satisfy awards issued under our Equity Plans.

Stock Options

Most of our stock options vest and become exercisable over a four to five year period and have a contractual life of 10 years. Certain stock options awarded are intended to qualify as incentive stock options pursuant to Section 422A of the Internal Revenue Code.

The following table summarizes stock option activity under the Equity Plans for the nine months ended June 30, 2015:

	Number of Shares		Weighted Average Exercise Price	Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value (*) (in thousands)
Outstanding as of September 30, 2014	1,431,190		$19.06
Granted	17,150		$5.68
Exercised	(225,736	)	$4.78		$	194
Forfeited	(9,077	)	$5.28
Expired	(297,499	)	$19.83
Outstanding as of June 30, 2015	916,028		$22.22	2.46	$	347
Exercisable as of June 30, 2015	891,351		$22.68	2.28	$	330
Vested and expected to vest as of June 30, 2015	911,032		$22.31	2.43	$	344

(*) Intrinsic value for stock options represents the “in-the-money” portion or the positive variance between a stock option's exercise price and the underlying stock price. For the nine months ended June 30, 2014, the intrinsic value of options exercised was $4,000.

As of June 30, 2015, there was approximately $0.2 million of unrecognized stock-based compensation expense, net of estimated forfeitures, related to non-vested stock options granted under the Equity Plans which is expected to be recognized over an estimated weighted average life of 3.8 years.

Valuation Assumptions

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option valuation model, adhering to the straight-line attribution approach using the following weighted-average assumptions, of which the expected term and stock price volatility rate are highly subjective:

	For the three months ended June 30,					For the nine months ended June 30,
	2015		2014			2015			2014
Black-Scholes weighted average assumptions:
Expected dividend rate	—	%	—		%	—		%	—		%
Expected stock price volatility rate	63.5	%	92.0		%	70.5		%	93.2		%
Risk-free interest rate	1.9	%	1.9		%	1.8		%	1.9		%
Expected term (in years)	6.0		6.0			6.0			6.0
Weighted average grant date fair value per share of stock options granted:	$3.59		$	3.21		$	3.57		$	3.61

Restricted Stock

Restricted stock units (RSUs) granted under the 2010 Equity Plan and 2012 Equity Plan typically vest over 3 years and are subject to forfeiture if employment terminates prior to the lapse of the restrictions. RSUs are not considered issued or outstanding common stock until they vest.

The following table summarizes the activity related to RSUs for the nine months ended June 30, 2015:

Restricted Stock Activity	Restricted Stock Units
	Number of Shares		Weighted Average Grant Date Fair Value
Non-vested as of September 30, 2014	966,579		$4.71
Granted	524,150		$5.38
Vested	(841,609	)	$4.69
Forfeited	(41,949	)	$4.86
Non-vested as of June 30, 2015	607,171		$5.23

As of June 30, 2015, there was approximately $2.5 million of remaining unamortized stock-based compensation expense, net of estimated forfeitures, associated with RSUs, which will be expensed over a weighted average remaining service period of approximately 2.3 years. The 0.6 million outstanding non-vested RSUs have an aggregate intrinsic value of approximately $3.7 million and a weighted average remaining contractual term of 1.4 years. For the nine months ended June 30, 2015 and 2014, the intrinsic value of RSUs vested was $4.4 million and $1.7 million, respectively. Of the 0.6 million outstanding non-vested RSUs, approximately 0.6 million are expected to vest and have an aggregate intrinsic value of approximately $3.4 million and a weighted average remaining contractual term of 1.4 years. For the nine months ended June 30, 2014, the weighted average grant date fair value of RSUs granted was $4.89.

On December 10, 2014, in connection with the sale of the Photovoltaics Business and the change in control, 0.3 million RSU's vested.

Geographical Information

Geographical Information

Following the sale of the Photovoltaics Business on December 10, 2014, the Company has one remaining reportable segment: Fiber Optics. See also Note 3 - Discontinued Operations for additional disclosures.

EMCORE's Fiber Optics business provides optical components, subsystems and systems for high-speed telecommunications, Cable Television (CATV), Wireless and Fiber-To-The-Premises (FTTP) networks, as well as products for satellite communications, video transport and specialty photonics technologies for defense and homeland security applications.

On October 22, 2014, EMCORE entered into the Digital Products Agreement with Neophotonics pursuant to which the Company agreed to sell the Digital Products Business to NeoPhotonics for an aggregate purchase price of $17.5 million, subject to certain purchase price adjustments. On January 2, 2015, EMCORE completed the sale of the Digital Products Business.

The financial results of the Photovoltaics and Digital Products Businesses are presented as "discontinued operations" on the consolidated statements of operations for the three and nine months ended June 30, 2015 and 2014; and the assets and liabilities of the Photovoltaics and Digital Products Businesses are presented as "Assets of discontinued operations" and "Liabilities of discontinued operations" on the condensed consolidated balance sheet as of September 30, 2014. No Photovoltaics or Digital Products assets and liabilities remain on the condensed consolidated balance sheet as of June 30, 2015.

We evaluate our reportable segments pursuant to ASC 280, Segment Reporting. The Company's Chief Executive Officer is the chief operating decision maker and he assesses the performance of the operating segments and allocates resources to segments based on their business prospects, competitive factors, net revenue, operating results, and other non-GAAP financial ratios. Based on this evaluation, the Company operates as a single reportable segment.

Revenue: The following tables set forth revenue by geographic region with revenue assigned to geographic regions based on our customers’ billing address and excludes discontinued operations. See also Note 3 - Discontinued Operations.

Credit Facilities

On November 11, 2010, we entered into a Credit and Security Agreement (credit facility) with Wells Fargo Bank, National Association ("Wells Fargo"). The credit facility is secured by the Company's assets and is subject to a borrowing base formula based on the Company's eligible accounts receivable, inventory, and machinery and equipment accounts.

On December 3, 2014, we entered into a Sixth Amendment to the credit facility pursuant to which Wells Fargo agreed to automatically release all encumbrances covering certain of the Company’s assets to be sold pursuant to the Photovoltaics Agreement and the Digital Products Agreement. In addition, on December 10, 2014, upon notice to Wells Fargo of the closing of the transaction contemplated by the Photovoltaics Agreement, the maximum borrowing allowed under the credit facility was reduced from $35.0 million to $15.0 million, and certain other changes to the borrowing base calculations went into effect.

As of June 30, 2015, there was no outstanding balance under this credit facility with an interest rate of 3.3% and approximately $1.2 million reserved for four stand-by letters of credit under the credit facility.

Income Tax Disclosure [Abstract]

Income and other Taxes

Income and other Taxes

At September 30, 2014, the Company determined that it was more likely than not that certain deferred tax assets would be realized upon the sale of the Photovoltaic Business in fiscal year 2015. As a result, a net deferred tax valuation allowance release of $24.1 million was recorded as an income tax benefit during fiscal year 2014. The sale of the Photovoltaic Business closed on December 10, 2014 and the Company realized a gain on the transaction.

For the three months ended June 30, 2015, the Company reported $0.5 million of income tax expense from continuing operations losses and $1.6 million of income tax benefit within income from discontinued operations. For the nine months ended June 30, 2015, the Company reported $1.9 million of income tax benefit from continuing operations losses and $26.5 million of income tax expense within income from discontinued operations. The income tax expense within discontinued operations includes estimated alternative minimum tax and other adjustments prescribed by ASC 740 in allocating expected annual income tax expense (benefit) between continuing operations and discontinued operations.

During the nine months ended June 30, 2015, the Company utilized $24.1 million of deferred tax assets. The Company paid alternative minimum taxes of $0.6 million in the three and nine months ended June 30, 2015 and the remaining income tax expense will be offset mainly through utilization of $24.1 million of deferred tax assets and utilization of net operating loss carry forwards.

For the three months ended June 30, 2014, the Company reported $0.7 million of income tax benefit from losses from continuing operations and $0.7 million of income tax expense within income from discontinued operations. For the nine months ended June 30, 2014, the Company reported $1.4 million of income tax benefit from losses from continuing operations and $1.4 million of income tax expense within income from discontinued operations.

For the three months ended June 30, 2015, the effective tax rate was 49.6%, compared to 14.4% for the three months ended June 30, 2014. The higher tax rate for June 30, 2015 is primarily due to the methodology used for allocating income tax expense between continuing and discontinued operations under ASC 740. For the nine months ended June 30, 2015, the effective tax rate on continuing operations was 33.8%, compared to 9.7% for the nine months ended June 30, 2014 primarily due to the benefit of the loss from operations in 2015. In determining the effective tax rate, the Company uses estimates to forecast the results from continuing operations for the current fiscal year as well as permanent differences between book and tax accounting. The Company believes its forecast of losses from continuing operations is a reasonable estimate. Actual results from continuing operations may differ significantly from the estimates previously forecasted, resulting in significant changes from one period to the next in the tax expense or benefit from continuing operations being recognized.

The Company expects all remaining deferred tax assets will have a full valuation allowance at September 30, 2015. However, on a quarterly basis, the Company will evaluate the positive and negative evidence to assess whether the more likely than not criterion, mandated by ASC 740, has been satisfied in determining whether there will be further adjustments to the valuation allowance.

During the three and nine months ended June 30, 2015 and 2014, there were no material increases or decreases in unrecognized tax benefits and we do not anticipate any material increases or decreases in the amounts of unrecognized tax benefits for the remainder of fiscal year 2015. As of June 30, 2015 and September 30, 2014, we had approximately $493,000 and $445,000, respectively, of interest and penalties accrued as tax liabilities on our balance sheet.

We file income tax returns in the U.S. federal, state, and local jurisdictions. The Company's September 30, 2012, federal return was under examination by the Internal Revenue Service. The examination was completed in April 2015 and the Company was notified there were no changes to the originally filed return. There are no state income tax returns under examination. The following tax years remain open to assessment for each of the more significant jurisdictions where we are subject to income taxes: after fiscal year 2010 for the U.S. federal and the State of New Mexico, and after fiscal year 2009 for the state of California.

Included in discontinued operations during the three and nine months ended June 30, 2015 were $0.2 million of incentive tax credits received. Included in discontinued operations for the three and nine months ended June 30, 2014 were $0.2 million and $0.8 million, respectively, of New Mexico incentive tax credits received. The amount received was allocated to cost of goods sold, selling, general and administrative and research and development expense primarily based on the number of employees allocated to the related departments. These credits resulted in cash refunds and a reduction of future payroll and compensation taxes.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements that are of significance, or of potential significance, to us other than those discussed below:

• In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This standard changes the criteria for reporting discontinued operations. Under the accounting standard update, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity's operations and financial results when either it qualifies as held for sale, disposed of by sale, or disposed of other than by sale. In addition, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. While early adoption is allowed, we have determined that we would not early adopt and as a result this accounting standard update will be effective for our fiscal year beginning on October 1, 2015. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

• In May 2014, as part of its ongoing efforts to assist in the convergence of U.S. GAAP and International Financial Reporting Standards, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Under the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. On July 9, 2015, the FASB voted to defer the effective date of implementation by one year. The new standard will be effective for us beginning October 1, 2018 and early adoption is permitted as of October 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We anticipate this standard will not have a material impact on our Condensed Consolidated Financial Statements.

• In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The standard provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. In addition, the standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The guidance is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. This accounting standard update will be effective for our fiscal year beginning October 1, 2017. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

• In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The standard simplifies the subsequent measurement of inventory. This standard requires inventory to be measured at the lower of cost and net realizable value and applies only to inventories for which cost is determined by methods other than last-in-first-out and the retail inventory method. Under this guidance, net realizable value is one of several calculations an entity needs to make to measure inventory at lower of cost or market. The guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. Early adoption is permitted. The new standard will be effective for our fiscal year beginning October 1, 2017. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.

Fair Value of Financial Instruments

ASC 820, Fair Value Measurements, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

• Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument.

• Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value.

A financial asset or liability's classification within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs.

Cash and Cash Equivalents

Cash consists primarily of bank deposits or, occasionally, highly liquid short-term investments with a maturity of three months or less at the time of purchase.

Restricted Cash

Restricted cash represents temporarily restricted deposits held as compensating balances against short-term borrowing arrangements.

Derivatives

All of our warrants met the classification requirements for liability accounting pursuant to ASC 815, Derivatives and Hedging

Receivables

The allowance for doubtful accounts is based on the age of receivables and a specific identification of receivables considered at risk of collection.

Severance and Restructuring Accruals

Expense related to severance and restructuring accruals is included in selling, general, and administrative expense on our statement of operations and comprehensive income (loss).

Asset Retirement Obligations

We have known conditional asset retirement conditions, such as certain asset decommissioning and restoration of rented facilities to be performed in the future. Our asset retirement obligations include assumptions related to renewal option periods for those facilities where we expect to extend lease terms. The Company recognizes its estimate of the fair value of its asset retirement obligations in the period incurred in long-term liabilities. The fair value of the asset retirement obligations is also capitalized as property, plant and equipment.

In future periods, the asset retirement obligation is accreted for the change in its present value and capitalized costs are depreciated over the useful life of the related assets. If the fair value of the estimated asset retirement obligation changes, an adjustment will be recorded to both the asset retirement obligation and the asset retirement capitalized cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, changes in estimated retirement costs, and changes in the estimated timing of settling asset retirement obligations.

Legal Proceedings

Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable.

Segment Reporting

We evaluate our reportable segments pursuant to ASC 280, Segment Reporting. The Company's Chief Executive Officer is the chief operating decision maker and he assesses the performance of the operating segments and allocates resources to segments based on their business prospects, competitive factors, net revenue, operating results, and other non-GAAP financial ratios. Based on this evaluation, the Company operates as a single reportable segment.
