II-VI Incorporated and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1. Basis of Presentation

The condensed consolidated financial statements of II-VI Incorporated (sometimes referred to herein as “II-VI” or the “Company”) for the three months ended September 30, 2012 and 2011 are unaudited. In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended June 30, 2012. The consolidated results of operations for the three months ended September 30, 2012 are not necessarily indicative of the results to be expected for the full fiscal year. The June 30, 2012 Condensed Consolidated Balance Sheet information was derived from the Company’s audited financial statements.

Effective July 1, 2012, the Company changed its reportable segments in accordance with how the Company’s chief operating decision maker receives and reviews financial information. Effective July 1, 2012, VLOC Incorporated (“VLOC”) has been included in the Military & Materials operating segment for financial reporting purposes. Prior to July 1, 2012, the Company’s VLOC business unit was included in the Near-Infrared Optics operating segment. The Company has revised the consolidated segment information for all periods presented in this Form 10-Q to reflect this reclassification.

Note 2. Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update related to impairment testing of indefinite-lived intangible assets. The update simplifies the guidance of testing for potential impairment of indefinite-lived intangible assets other than goodwill. The amendment provides entities the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. An entity electing to perform a qualitative assessment is no longer required to calculate the fair value of an indefinite-lived intangible asset unless the organization determines, based on a qualitative assessment, that it is “more likely than not” (that is, a likelihood of more than 50 percent) that the asset is impaired. The amendments in this update are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements and indefinite-lived intangible asset impairment testing.

In September 2011, the FASB issued an accounting standard update related to goodwill impairment testing. The objective of the accounting standard update is to simplify how entities test goodwill for impairment by permitting an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This update also allows entities an unconditional option to bypass this qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. This accounting standard update is effective for annual and interim goodwill impairment tests performed for fiscal years beginning on or after December 15, 2011, with early adoption permitted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements and goodwill impairment testing.

In June 2011, the FASB issued changes to the presentation of comprehensive income that require entities to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity is no longer permitted. This guidance, with retrospective application, was adopted by the Company in the first quarter of fiscal year 2013. Other than the change in presentation, these changes have had no impact on the consolidated financial statements and the calculation and presentation of earnings per share.

Note 3. Investment

The Company has a total equity investment in Guangdong Fuxin Electronic Technology based in Guangdong Province, China of 20.2%, which is accounted for under the equity method of accounting. The total carrying value of the investment recorded at September 30, 2012 and June 30, 2012 was $11.0 million and $10.7 million, respectively. During each of the three months ended September 30, 2012 and 2011, the Company’s pro-rata share of earnings from this investment was $0.4 million which was recorded in other expense (income), net in the Condensed Consolidated Statements of Earnings.

Note 4. Inventories

	$	151,762		$	153,918

Note 6. Goodwill and Other Intangible Assets

Changes in the carrying amount of goodwill are as follows ($000):

	Three Months Ended September 30, 2012
	Infrared Optics		Near-Infrared Optics			Military & Materials		Advanced Products Group		Total
Balance – beginning of period	$	9,612	$	48,496		$	12,326	$	10,314	$	80,748
Foreign currency translation		83		(83	)		—		—		—
Balance – end of period	$	9,695	$	48,413		$	12,326	$	10,314	$	80,748

The Company reviews the recoverability of goodwill at least annually and any time business conditions indicate a potential change in recoverability. The measurement of a potential impairment begins with comparing the current fair value of the Company’s reporting units to the recorded value (including goodwill). The Company uses a discounted cash flow model (“DCF model”) and a market analysis to determine the current fair value of its reporting units. A number of significant assumptions

9

and estimates are involved in estimating the forecasted cash flows used in the DCF model, including markets and market shares, sales volume and pricing, costs to produce, working capital changes and income tax rates. Management considers historical experience and all available information at the time the fair values of the reporting units are estimated. However, actual fair values that could be realized could differ from those used to evaluate the impairment of goodwill.

The gross carrying amount and accumulated amortization of the Company’s intangible assets other than goodwill as of September 30, 2012 and June 30, 2012 was as follows ($000):

	September 30, 2012							June 30, 2012
	Gross Carrying Amount		Accumulated Amortization			Net Book Value		Gross Carrying Amount		Accumulated Amortization			Net Book Value
Patents	$	21,854	$	(8,078	)	$	13,776	$	21,856	$	(7,640	)	$	14,216
Trademarks		13,166		(907	)		12,259		13,166		(888	)		12,278
Customer Lists		25,868		(8,933	)		16,935		25,816		(8,296	)		17,520
Other		1,378		(1,378	)		—		1,375		(1,375	)		—
Total	$	62,266	$	(19,296	)	$	42,970	$	62,213	$	(18,199	)	$	44,014

Amortization expense recorded on these intangible assets was $1.1 million and $1.0 million, for the three months ended September 30, 2012 and 2011, respectively. The patents are being amortized over a range of 120 to 240 months with a weighted average remaining life of approximately 121 months. The customer lists are being amortized over approximately 120 months with a weighted average remaining life of approximately 97 months. The gross carrying amount of trademarks includes $11.4 million of acquired trade names resulting from past acquisitions. These trade names have indefinite lives and are not amortized but tested annually for impairment or more frequently if a triggering event occurs. Included in the gross carrying amount and accumulated amortization of the Company’s intangible assets is the effect of foreign currency translation on that portion of the intangible assets relating to the Company’s German subsidiaries, Photop Technologies, Inc. (“Photop”) and AOFR Pty. Ltd. (“AOFR”).

At September 30, 2012, the estimated amortization expense for existing intangible assets for each of the five succeeding fiscal years is as follows ($000):

Year Ending June 30,
Remaining 2013	$	3,163
2014		3,744
2015		3,479
2016		3,411
2017		3,402

Note 7. Debt

The components of debt for the periods indicated were as follows ($000):

	September 30, 2012		June 30, 2012
Line of credit, interest at the LIBOR Rate, as defined, plus 0.625%	$	14,000	$	9,000
Yen denominated line of credit, interest at the LIBOR Rate, as defined, plus 0.625%		3,865		3,769
Total debt		17,865		12,769
Current portion of long-term debt		—		—
Long-term debt, less current portion	$	17,865	$	12,769

At September 30, 2012, the Company’s credit facility was a $50.0 million unsecured line of credit which, under certain conditions, could be expanded to $80.0 million. The credit facility has a five-year term through June 2016 and has an interest rate of LIBOR, as defined in the agreement, plus 0.625% to 1.50%. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of September 30, 2012, the Company was in compliance with all financial covenants. See “Note 15. Subsequent Events”.

10

The Company’s Yen denominated line of credit is a 500 million Yen facility that has a five-year term through June 2016 and has an interest rate equal to the LIBOR Rate, as defined in the loan agreement, plus 0.625% to 1.50%. At September 30, 2012 and June 30, 2012, the Company had 300 million Yen borrowed. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of September 30, 2012, the Company was in compliance with all financial covenants.

The Company had aggregate availability of $37.2 million and $42.3 million under its lines of credit as of September 30, 2012 and June 30, 2012, respectively. The amounts available under the Company’s lines of credit are reduced by outstanding letters of credit. As of September 30, 2012 and June 30, 2012, total outstanding letters of credit supported by the credit facilities were $0.9 million.

The weighted average interest rate of total borrowings was 0.89% and 1.01% for the three months ended September 30, 2012 and 2011.

Note 8. Income Taxes

The Company’s year-to-date effective income tax rate at September 30, 2012 and 2011 was 24.2% and 23.9%, respectively. The variations between the Company’s effective tax rates and the U.S. statutory rate of 35.0% were primarily due to the consolidation of the Company’s foreign operations, which are subject to income taxes at lower statutory rates. A change in the mix of pretax income from these various tax jurisdictions could have a material impact on the Company’s effective tax rate.

U.S. GAAP clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of September 30, 2012 and June 30, 2012, the gross unrecognized income tax benefit was $3.0 million and $2.9 million, respectively. The Company has classified the uncertain tax positions as non-current income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, substantially all of the gross unrecognized tax benefits at September 30, 2012 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision on the Condensed Consolidated Statements of Earnings. The amount of accrued interest and penalties included in the $3.0 million and $2.9 million of gross unrecognized income tax benefit at September 30, 2012 and June 30, 2012 was immaterial. Fiscal years 2010 to 2012 remain open to examination by the United States Internal Revenue Service, fiscal years 2008 to 2012 remain open to examination by certain state jurisdictions, and fiscal years 2005 to 2012 remain open to examination by certain foreign taxing jurisdictions.

Note 9. Earnings Per Share

The following table sets forth the computation of earnings per share attributable to II-VI Incorporated for the periods indicated. Weighted average shares issuable upon the exercises of stock options and the release of performance and restricted shares that were not included in the calculation were approximately 380,000 and 124,000 for the three months ended September 30, 2012 and 2011, respectively, because they were anti-dilutive ($000 except per share data):

Note 10. Segment Reporting

The Company reports its business segments using the “management approach” model for segment reporting. The Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing performance.

Effective July 1, 2012, the Company’s VLOC business unit has been included in the Military & Materials operating segment for financial reporting purposes in accordance with how the Company’s chief operating decision maker receives and reviews financial information. Prior to July 1, 2012, VLOC was included in the Near-Infrared Optics operating segment. The Company has revised the consolidated segment information for all periods presented in this Form 10-Q to reflect this reclassification.

The Company has four reportable segments. The Company’s chief operating decision maker receives and reviews financial information in this format. The Company evaluates business segment performance based upon reported business segment earnings, which is defined as earnings before income taxes, interest and other income or expense. The segments are managed separately due to the production requirements and facilities that are unique to each segment. The Company had the following reportable segments at September 30, 2012: (i) Infrared Optics, which consists of the Company’s infrared optics and material products businesses, HIGHYAG Lasertechnologie GmbH (“HIGHYAG”) and certain remaining corporate activities, primarily corporate assets and capital expenditures; (ii) Near-Infrared Optics, which consists of Photop, Aegis Lightwave, Inc. and AOFR; (iii) Military & Materials, which consists of the Company’s Exotic Electro-Optics, Inc. (“EEO”) subsidiary, VLOC, Max Levy Autograph (“MLA”), and Pacific Rare Speciality Metals & Chemicals, Inc. (“PRM”); and (iv) Advanced Products Group, which is comprised of the Company’s Marlow Industries, Inc. (“Marlow”) subsidiary, the Wide Bandgap Materials Group (“WBG”) and the Worldwide Materials Group (“WMG”); WMG is responsible for the corporate research and development activities.

The Infrared Optics segment is divided into geographic locations in the U.S., Singapore, China, Germany, Switzerland, Japan, Belgium, the U.K. and Italy. The Infrared Optics segment is directed by a general manager, while each geographic location is also directed by a general manager, and is further divided into production and administrative units that are directed by managers. The Infrared Optics segment designs, manufactures and markets optical and electro-optical components and materials sold under the II-VI brand name and used primarily in high-power CO₂ lasers. The Infrared Optics segment also manufactures fiber-delivered beam delivery systems and processing tools for industrial lasers sold under the HIGHYAG brand name.

The Near-Infrared Optics segment is located in the U.S., China, Vietnam, Australia, Germany, Japan, the U.K., Italy and Hong Kong. The Near-Infrared Optics segment is directed by a Corporate Executive Vice President and is further divided into production and administrative units that are directed by managers. The Near-Infrared Optics segment manufactures crystal materials, optics, microchip lasers and opto-electronic modules for use in optical communication networks and other diverse consumer and commercial applications sold under the Photop brand name and manufactures tunable optical devices and couplers and combiners required for high speed optical networks sold under the Aegis and AOFR brand names, respectively.

The Military & Materials segment is located in the U.S. and the Philippines. The Military & Materials segment is directed by a Corporate Vice President, while each geographic location is directed by a general manager. The Military & Materials segment is further divided into production and administrative units that are directed by managers. The Military & Materials segment designs, manufactures and markets infrared products for military applications under the EEO brand name, refines specialty metals and rare earth elements, primarily selenium and tellurium, under the PRM brand name, and manufactures and markets micro-fine conductive mesh patterns for optical, mechanical, and ceramic components for applications under the MLA brand name. The Military & Materials segment also designs, manufactures and markets near-infrared and visible-light products for military applications and laser gain material and products for solid-state yttrium aluminum garnet (“YAG”) lasers, yttrium lithium fluoride (“YLF”) lasers and Ultra-Violet (“UV”) Filter components sold under the VLOC brand name.

The Advanced Products Group is located in the U.S., Vietnam, Japan, China and Germany and is directed by a Corporate Executive Vice President. In the Advanced Products Group segment, Marlow designs and manufactures thermoelectric cooling and power generation solutions for use in defense and space, optical communications, medical, consumer and

12

industrial markets. WBG manufactures and markets single crystal silicon carbide substrates for use in solid-state lighting, wireless infrastructure, radio frequency (“RF”) electronics and power switching industries. WMG directs the corporate research and development initiatives.

The accounting policies of the segments are the same as those of the Company. All of the Company’s corporate expenses are allocated to the segments. The Company evaluates segment performance based upon reported segment earnings, which is defined as earnings before income taxes, interest and other income or expense. Inter-segment sales and transfers have been eliminated.

The following tables summarize selected financial information of the Company’s operations by segment:

Note 11. Share-Based Compensation

The Board of Directors adopted the II-VI Incorporated 2009 Omnibus Incentive Plan (the “Plan”) which was approved by the shareholders of the Company. The Plan provides for the grant of non-qualified stock options, stock appreciation rights, restricted share awards, restricted share units, deferred share awards, performance share awards and performance share units to employees, officers, directors and consultants of the Company. The Company records share-based compensation expense for these awards in accordance with U.S. GAAP, which requires the recognition of the fair value of share-based compensation in net earnings. The Company recognizes the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period.

13

During the three months ended September 30, 2012 and 2011, the Company recorded $3.6 million and $4.6 million, respectively, of share-based compensation expense in its Condensed Consolidated Statements of Earnings. The share-based compensation expense is allocated approximately 20% to cost of goods sold and 80% to selling, general and administrative expense in the Condensed Consolidated Statements of Earnings, based on the employee classification of the grantees.

Stock Options and Stock Appreciation Rights:

The Company utilizes the Black-Scholes valuation model for estimating the fair value of these awards. During the three months ended September 30, 2012 and 2011, the weighted-average fair values of awards granted under the Plan were $8.49 and $9.33 per award, respectively, using the following assumptions:

	Three Months Ended September 30, 2012			Three Months Ended September 30, 2011
Risk free interest rate		0.93	%		1.07	%
Expected volatility		49	%		59	%
Expected life of options		5.65 years			5.51 years
Dividend yield		None			None

The risk-free interest rate is derived from the average U.S. Treasury Note rate during the period, which approximates the rate in effect at the time of grant related to the expected life of the awards. The risk free interest rate shown above is the weighted average rate for all awards granted during the fiscal year. Expected volatility is based on the historical volatility of the Company’s Common Stock over the period commensurate with the expected life of the awards. The expected life calculation is based on the observed time to post-vesting exercise and/or forfeitures of awards by our employees. The dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no intention to pay cash dividends in the future. The estimated annualized forfeitures are based on the Company’s historical experience of award cancellations pre-vesting and are estimated at a rate of 16%. The Company will record additional expense in future periods if the actual forfeiture rate is lower than estimated, and will adjust expense in future periods if the actual forfeitures are higher than estimated.

Included in the $3.6 million and $4.6 million of share-based compensation expense for the three months ended September 30, 2012 and 2011, respectively, was $1.6 million and $2.9 million of share-based compensation expense related to these awards.

Restricted Share Awards and Restricted Share Units:

The restricted share awards and units compensation expense was calculated based on the number of shares or units expected to be earned by the grantee multiplied by the stock price at the date of grant and is being recognized over the vesting period. Generally, the restricted share awards and units have a three year cliff-vesting provision and an estimated forfeiture rate of 7.5%. Included in the $3.6 million and $4.6 million of share-based compensation expense for the three months ended September 30, 2012 and 2011, respectively, was $1.1 million and $0.8 million, respectively, of share-based compensation expense related to restricted share awards and units.

Performance Share Awards and Performance Share Units:

The Compensation Committee of the Board of Directors of the Company has granted certain named executive officers and employees performance share awards and units under the Plan. As of September 30, 2012, the Company had outstanding grants covering performance periods ranging from 24 to 48 months. These awards are intended to provide continuing emphasis on specified financial performance goals that the Company considers important contributors to long-term shareholder value. These awards are payable only if the Company achieves specified levels of financial performance during the performance periods.

In conjunction with the Company’s acquisition of Photop, the Compensation Committee established both a short-term and long-term performance and retention program under the Plan for certain Photop employees. As of September 30, 2012, a portion of this long-term performance and retention program was still outstanding, covering a performance period from January 1, 2012 to December 31, 2012. The remaining long-term retention and performance awards are payable only if Photop achieves the levels of revenue and earnings specified for the outstanding performance period as well as certain other pre-established non-financial performance targets.

14

The performance share awards and units compensation expense is calculated based on the estimated number of shares or units expected to be earned multiplied by the stock price at the date of grant. Included in the $3.6 million and $4.6 million of share-based compensation expense for each of the three months ended September 30, 2012 and 2011, respectively, was $0.9 million of share-based compensation expense related to performance share awards and units.

Note 12. Fair Value of Financial Instruments

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

• Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

• Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

• Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. At September 30, 2012 and 2011, the Company had foreign currency forward contracts in Japanese Yen recorded at fair value. The fair values of these instruments were measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk and restrictions and other terms specific to the contracts. These contracts are recorded in Other accrued liabilities or Prepaid and other current assets in the Company’s Condensed Consolidated Balance Sheets. The change in the fair value of these contracts for the three months ended September 30, 2012 and 2011 was insignificant.

Note 13. Commitments and Contingencies

The Company records a warranty reserve as a charge against earnings based on a percentage of sales utilizing actual returns over the last twelve months. The following table summarizes the change in the carrying value of the Company’s warranty reserve, which is a component of Other accrued liabilities in the Company’s Condensed Consolidated Balance Sheets, as of and for the three months ended September 30, 2012 ($000):

	Three Months Ended September 30, 2012
Balance – Beginning of Period	$	1,247
Payments made during the period		(358	)
Additional warranty liability recorded during the period		365
Balance – End of Period	$	1,254

Note 14. Share Repurchase Program

In May 2012, the Board of Directors authorized the Company to purchase up to $25 million of its Common Stock. The repurchase program called for shares to be purchased in the open market or in private transactions from time to time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. During the fiscal period ended September 30, 2012, the Company purchased 317,042 shares of its common stock pursuant to the share repurchase program for approximately $5.9 million. As of September 30, 2012, the Company has purchased a total of 618,756 shares of its common stock for approximately $10.9 million under this share repurchase program.

Note 15. Subsequent Events

On November 1, 2012, the Company, through a merger involving a wholly-owned subsidiary of II-VI, acquired all of the outstanding shares of M Cubed Technologies, Inc. (“M Cubed”), a privately held company with operations in Connecticut

15

and Delaware for approximately $71.4 million, subject to a potential post-closing working capital adjustment that could increase the purchase price by up to $2.5 million. M Cubed develops advanced ceramic materials and precision motion control products addressing the semiconductor, crystal display, industrial and defense markets. The final purchase price will be subject to customary closing adjustments, including working capital adjustments. The results for the three months ended September 30, 2012 do not include any operating results of M Cubed, but do include certain transaction-related expenses attributable to the acquisition of M Cubed of approximately $0.5 million, pre-tax, which are required to be expensed under current accounting standards. Due to the timing of the acquisition of M Cubed, the final purchase price allocation and related accounting for M Cubed was not available as of the filing date of this Quarterly Report on Form 10-Q. This information will be disclosed in future filings.

On October 31, 2012, the Company exercised the accordion feature of its existing $50 million unsecured credit facility to increase the size of its credit facility from $50 million to $80 million. Except as described above, the credit facility continues pursuant to its existing terms and conditions. The Company used a portion of its increased available credit facility to finance the acquisition of M Cubed. Total long-term debt of the Company immediately following the acquisition of M Cubed was approximately $82 million.

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

Forward-Looking Statements

This Management’s Discussion and Analysis contains forward-looking statements as defined by Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding projected growth rates, markets, product development, financial position, capital expenditures and foreign currency exposure. Forward-looking statements are also identified by words such as “expects,” “anticipates,” “intends,” “plans,” “projects” or similar expressions.

Actual results could materially differ from such statements due to the following factors: materially adverse changes in economic or industry conditions generally (including capital markets) or in the markets served by the Company, the development and use of new technology and the actions of competitors. There are additional risk factors that could affect the Company’s business, results of operations or financial condition. Investors are encouraged to review the risk factors set forth in the Company’s most recent Form 10-K as filed with the Securities and Exchange Commission on August 28, 2012, and herein.

Introduction

II-VI Incorporated (“II-VI,” the “Company,” “we,” “us” or “our”), the worldwide leader in engineered materials and opto-electronic components, is a vertically-integrated manufacturing company that creates and markets products for diversified markets including industrial manufacturing, military and aerospace, high-power electronics, optical communications, medical and thermoelectronics applications.

The Company generates revenues, earnings and cash flows from developing, manufacturing and marketing engineered materials and opto-electronic components for precision use in industrial, military, optical communications, photovoltaic, medical and consumer applications. We also generate revenue, earnings and cash flows from government-funded research and development contracts relating to the development and manufacture of new technologies, materials and products.

Our customer base includes original equipment manufacturers (“OEMs”), laser end users, system integrators of high-power lasers, manufacturers of equipment and devices for industrial, optical communications, security and monitoring applications, U.S. government prime contractors, various U.S. government agencies and thermoelectric solutions suppliers.

Effective July 1, 2012, the Company changed its reportable segments in accordance with how the Company’s chief operating decision maker receives and reviews financial information. Effective July 1, 2012, VLOC has been included in the Military & Materials operating segment for financial reporting purposes. Prior to July 1, 2012, the Company’s VLOC business unit was included in the Near-Infrared Optics operating segment. The Company has revised the consolidated segment information for all periods presented in this Form 10-Q to reflect this reclassification.

Critical Accounting Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America and the Company’s discussion and analysis of its financial condition and results of operations require the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its condensed consolidated financial statements and accompanying notes. Note 1 of the Notes to Consolidated Financial

16

Statements in the Company’s most recent Form 10-K describes the significant accounting policies and methods used in the preparation of the Company’s consolidated financial statements. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates.

Management believes the Company’s critical accounting estimates are those related to revenue recognition, allowance for doubtful accounts, warranty reserves, inventory valuation, valuation of long-lived assets including acquired intangibles and goodwill, accrual of bonus and profit sharing estimates, accrual of income tax liability estimates and accounting for share-based payments. Management believes these estimates to be critical because they are both important to the portrayal of the Company’s financial condition and results of operations, and they require management to make judgments and estimates about matters that are inherently uncertain.

The Company recognizes revenues in accordance with U.S. GAAP. Revenues for product shipments are realizable when we have persuasive evidence of a sales arrangement, the product has been shipped or delivered, the sale price is fixed or determinable and collectability is reasonably assured. Title and risk of loss passes from the Company to its customer at the time of shipment in most cases with the exception of certain customers. For these customers title does not pass and revenue is not recognized until the customer has received the product at its physical location. The Company’s revenue recognition policy is consistently applied across the Company’s segments, product lines and geographical locations. Further, we do not have post shipment obligations such as training or installation, customer acceptance provisions, credits and discounts, rebates and price protection or other similar privileges. Our distributors and agents are not granted price protection. Our distributors and agents, who comprise less than 10% of consolidated revenue, have no additional product return rights beyond the right to return defective products that are covered by our warranty policy. We believe our revenue recognition practices are consistent with Staff Accounting Bulletin (“SAB”) 104 and that we have adequately considered the requirements of Accounting Standards Codification (“ASC”) 605 Revenue Recognition. Revenues generated from transactions other than product shipments are contract-related and have historically accounted for less than 5% of the Company’s consolidated revenues.

We establish an allowance for doubtful accounts and warranty reserves based on historical experience and believe the collection of revenues, net of these reserves, is reasonably assured. Our allowance for doubtful accounts and warranty reserve balances at September 30, 2012 were $2.0 million and $1.3 million, respectively. Our reserve estimates have historically been proven to be materially correct based upon actual charges incurred. The company had one customer that represented 13% of total accounts receivable as of September 30, 2012.

New Accounting Standards

Executive Summary

During the three months ended September 30, 2012, the Company began to see slowing order patterns across the majority of its business units as further political and economic uncertainty worldwide resulted in a reduction of orders from an already cautious customer base. Net earnings attributable to II-VI Incorporated for the three months ended September 30, 2012 decreased to $12.7 million ($0.20 per-share diluted) compared to $18.6 million ($0.29 per-share diluted) for the same period last fiscal year. Revenues decreased slightly from the same period last fiscal year, while gross margin was negatively impacted by PRM due to lower selling prices of tellurium and selenium shipped to customers, as well as changes in product mix at Marlow and unfavorable absorption of manufacturing overhead costs combined with higher raw material input prices at several of the Company’s business units. The negative impacts on gross margin were somewhat offset by a favorable change in product mix at the Company’s Photop and Aegis business units. The Company continued to invest resources in research and development activities at Photop and Aegis while managing worldwide operating costs to ensure proper alignment with current revenue levels.

Consolidated

Bookings. Bookings for the three months ended September 30, 2012 decreased 12.1% to $114.4 million, compared to $130.2 million for the same period last fiscal year. Bookings are defined as customer orders received that are expected to be converted to revenues over the next twelve months. For long-term customer orders, the Company does not include in bookings the portion of the customer order that is beyond twelve months, due to the inherent uncertainty of an order that far out in the future. The decline in overall bookings levels is attributable to lower orders in the Infrared Optics, Military & Materials and Advanced Products Group segments, offset somewhat by bookings increases at Photop and Aegis within the Company’s Near-Infrared Optics segment. The decreased bookings at Infrared Optics was mostly attributable to reduced demand from Japanese OEMs in the high-power CO₂ laser market, while slowing demand for Marlow’s gesture recognition product line within the Advanced Products Group continued to put downward pressure on bookings. Within the Military & Materials segment, PRM experienced lower bookings as a result of reduced orders and pricing for selenium and tellurium while bookings at VLOC were unfavorably impacted by the timing of receipt of a large UV Filter military order. The Company’s Photop and Aegis subsidiaries within the Near-Infrared Optics segment offset a portion of the bookings declines due to increased order intake from large optical communication customers in Asia.

Revenues. Revenues for the three months ended September 30, 2012 decreased 4.4% to $132.3 million, compared to $138.4 million for the same period last fiscal year. The decrease in revenues was attributable to PRM and VLOC within the Military & Materials segment and Marlow within the Advanced Products Group segment. These decreases in revenue were somewhat offset by higher revenue at Photop and Aegis within the Near-Infrared Optics segment. PRM revenue decreased as a result of

18

lower shipment volumes and selling prices to customers for both its selenium and tellurium minor metals while revenue at VLOC decreased as a result of lower product demand for military applications. Marlow experienced lower shipment volume of gesture recognition product as a result of decreased demand, while higher revenue levels at Photop and Aegis were the result of increased sales volumes to multiple Asian optical communication customers.

Gross margin. Gross margin for the three months ended September 30, 2012 was $48.8 million or 36.9% of total revenues, compared to $55.0 million or 39.8% of total revenues, for the same period last fiscal year. The decline in gross margin was mostly due to a reduction in the selling prices at PRM of both tellurium and selenium as well as the decline in gesture recognition shipment volume at the Company’s Marlow business unit which typically yields a high margin profile. Gross margin within the Company Infrared Optics segment was also impacted by higher input prices of raw materials used in production. Somewhat offsetting these negative impacts on gross margin was a shift in product mix at Photop and Aegis, which realized higher margins on a large concentration of optical communication and high-power fiber laser couplers and combiners, respectively.

Internal research and development. Company-funded internal research and development expenses for the three months ended September 30, 2012 were $5.6 million, or 4.2% of revenues, compared to $5.2 million, or 3.7% of revenues, for the same period last fiscal year. This increase in Company-funded internal research and development expenses was primarily the result of ongoing research and development investment at Photop and Aegis within the Near-Infrared optics segment. Photop is focusing research and development efforts on optical communication and commercial optic markets, specifically regarding components and module products that will be utilized by customers to satisfy future high-speed network requirements. Aegis continues to invest in new product development of high performance flexible bandwidth optical channel monitors and high-power fiber laser couplers and combiners.

Selling, general and administrative. Selling, general and administrative expenses for the three months ended September 30, 2012 were $26.7 million or 20.1% of revenues, compared to $26.8 million, or 19.4% of revenues, for the same period last fiscal year. Selling, general and administrative expense as a percentage of revenues increased slightly during the three months ended September 30, 2012 compared to the same periods last fiscal year, mostly as a result of incremental operating costs outpacing revenues.

Interest and other, net. Interest and other, net for the three months ended September 30, 2012 was income of $0.7 million. Included in interest and other, net for the three months ended September 30, 2012 are earnings from the Company’s equity investment in Fuxin, net interest income on excess cash reserves and unrealized gains on the deferred compensation plan that were somewhat offset by foreign currency losses. The majority of interest and other, net for the three months ended September 30, 2011 was the result of a $1.4 million gain related to the sale of precious metals inventory, earnings of equity investments, net interest income on excess cash reserves, foreign currency losses and unrealized losses on the deferred compensation plan.

Income taxes. The Company’s year-to-date effective income tax rate at September 30, 2012 was 24.2%, compared to an effective tax rate of 23.9% for the same period last fiscal year. The variation between the Company’s effective tax rate and the U.S. statutory rate of 35% is primarily due to the Company’s foreign operations which are subject to income taxes at lower statutory rates.

Segment Reporting

Effective July 1, 2012, the Company’s VLOC business unit has been included in the Military & Materials operating segment for financial reporting purposes in accordance with how the Company’s chief operating decision maker receives and reviews financial information. Prior to July 1, 2012, VLOC was included in the Near-Infrared Optics operating segment. The Company has revised the consolidated segment information to reflect this reclassification for all periods presented in Part I, Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Quarterly Report on Form 10-Q.

Bookings, revenues and segment earnings for the Company’s reportable segments are discussed below. Segment earnings differ from income from operations in that segment earnings exclude certain operational expenses included in other expense (income) – net as reported. Management believes segment earnings to be a useful measure as it reflects the results of segment performance over which management has direct control and is used by management in its evaluation of segment performance. See “Note 10. Segment Reporting,” to our unaudited financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information on the Company’s reportable segments and for the reconciliation of segment earnings to net earnings.

Infrared Optics (millions)

	Three Months Ended September 30,				% Increase (Decrease)
	2012		2011
Bookings	$	47.5	$	51.1		(7	)%
Revenues	$	51.6	$	50.8		1	%
Segment earnings	$	11.8	$	12.4		(4	)%

The Company’s Infrared Optics segment includes the combined operations of Infrared Optics and HIGHYAG.

Bookings for the three months ended September 30, 2012 for Infrared Optics decreased 7% to $47.5 million, compared to $51.1 million for the same period last fiscal year. The decrease in bookings for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily driven by decreased demand from OEMs for new high-power CO₂ laser systems in Japan and Europe somewhat offset by increased orders at HIGHYAG for one-micron beam delivery system welding heads. The stagnant Japanese economy as well as fiscal uncertainty in Europe, has contributed to the lower demand for new high-power CO₂ laser systems in these geographic locations.

Revenues for the three months ended September 30, 2012 for Infrared Optics increased 1% to $51.6 million, compared to $50.8 million for the same period last fiscal year. This slight increase in revenue reflects higher shipment volume at HIGHYAG for one-micron laser welding heads, somewhat offset by decreased revenue within Infrared Optics as a result of cautious buying patterns from customers in Asia and Europe.

Segment earnings for the three months ended September 30, 2012 for Infrared Optics decreased 4% to $11.8 million, compared to $12.4 million for the same period last fiscal year. The decrease in segment earnings for the three months ended September 30, 2012 compared to the same periods last fiscal year was primarily due to lower gross margins caused by higher raw material input prices.

Near-Infrared Optics (millions)

	Three Months Ended September 30,				% Increase
	2012		2011
Bookings	$	35.1	$	31.8		10	%
Revenues	$	40.6	$	31.0		31	%
Segment earnings	$	7.7	$	2.6		202	%

The Company’s Near-Infrared Optics segment includes the combined operations of Photop and Aegis.

Bookings for the three months ended September 30, 2012 for Near-Infrared Optics increased 10% to $35.1 million, compared to $31.8 million for the same period last fiscal year. The increase in bookings for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily driven by increased order intake at both Photop and Aegis for green laser devices and optical channel monitors, respectively.

Revenues for the three months ended September 30, 2012 for Near-Infrared Optics increased 31% to $40.6 million, compared to $31.0 million for the same period last fiscal year. The increase in revenues for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily driven by higher shipment volumes at Photop to large Chinese optical communication customers as well as increased revenues earned by providing contract manufacturing services.

Segment earnings for the three months ended September 30, 2012 for Near-Infrared Optics increased 202% to $7.7 million, compared to $2.6 million for the same period last fiscal year. The increase in segment earnings was driven by the incremental revenues at Photop as well as higher gross margins as a shift in product mix to optical communication products with higher margin profiles more than offset increased spending on research and development activities.

20

Military & Materials (millions)

	Three Months Ended September 30,					% (Decrease)
	2012			2011
Bookings	$	17.7		$	26.4		(33	)%
Revenues	$	23.9		$	30.8		(22	)%
Segment (loss) earnings	$	(2.1	)	$	2.1		(202	)%

The Company’s Military & Materials segment includes the combined operations of EEO, PRM, VLOC, and MLA.

Bookings for the three months ended September 30, 2012 for Military & Materials decreased 33% to $17.7 million, compared to $26.4 million for the same period last fiscal year. The decrease in bookings for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily driven by reduced demand at both PRM and VLOC. Bookings at PRM were negatively impacted due to reduced orders for selenium and tellurium as well as lower index pricing of these materials. At VLOC, continued pressure and propositions to reduce U.S. defense spending as well as the timing of UV Filter orders had a negative impact on bookings.

Revenues for the three months ended September 30, 2012 for Military & Materials decreased 22% to $23.9 million, compared to $30.8 million for the same period last fiscal year. The decrease in revenues for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily due to lower shipments at VLOC resulting from reduced military orders as well as lower product demand for both tellurium and selenium at PRM.

Segment (loss) earnings for the three months ended September 30, 2012 for Military & Materials was a segment loss of $2.1 million, compared to segment earnings of $2.1 million for the same period last fiscal year. The unfavorable change in segment (loss) earnings for the three months ended September 30, 2012 was mostly due to the aforementioned reduced revenues as well as reduced gross margins at VLOC and PRM. The unfavorable gross margin change at VLOC was mostly due to unfavorable absorption of manufacturing overhead costs while PRM’s gross margin was negatively impacted by lower selling prices of tellurium to customers.

Advanced Products Group (millions)

	Three Months Ended September 30,					% (Decrease)
	2012			2011
Bookings	$	14.0		$	21.0		(33	)%
Revenues	$	16.2		$	25.8		(37	)%
Segment (loss) earnings	$	(0.8	)	$	6.0		(114	)%

The Company’s Advanced Products Group includes the combined operations of Marlow, WBG and WMG.

Bookings for the three months ended September 30, 2012 for the Advanced Products Group decreased 33% to $14.0 million, compared to $21.0 million for the same period last fiscal year. The decrease in bookings for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily due to a significant reduction in demand for Marlow’s gesture recognition product line.

Revenues for the three months ended September 30, 2012 for the Advanced Products Group decreased 37% to $16.2 million, compared to $25.8 million for the same period last fiscal year. The decrease in revenues for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily due to lower shipment volumes of gesture recognition and telecommunication products at Marlow.

Segment (loss) earnings for the three months ended September 30, 2012 decreased 114% to a segment loss of $0.8 million, compared to segment earnings of $6.0 million for the same period last fiscal year. The unfavorable change in segment (loss) earnings for the three months ended September 30, 2012 compared to the same period last fiscal year was primarily due to the lower revenues as well as declining gross margin at Marlow resulting from unfavorable product mix as gesture recognition sales with higher margin profiles have relented.

Liquidity and Capital Resources

Historically, our primary source of cash has been provided through operations. Other sources of cash include proceeds received from the exercises of stock options and long-term borrowings. Our historical uses of cash have been for capital expenditures, purchases of businesses, payment of principal and interest on outstanding debt obligations and purchases of treasury stock. Supplemental information pertaining to our sources and uses of cash for the periods indicated is presented as follows:

Sources (uses) of Cash (millions):

	Three Months Ended September 30,
	2012			2011
Net cash provided by operating activities	$	23.2		$	14.3
Proceeds from exercises of stock options		1.1			0.2
Purchase of business, net of cash acquired		—			(46.1	)
Additions to property, plant and equipment		(5.9	)		(12.7	)
Net proceeds on long-term borrowings		5.0			5.7
Purchases of treasury shares		(5.9	)		—
Other		0.2			(0.1	)

Cash provided by operating activities was $23.2 million for the three months ended September 30, 2012, compared to cash provided by operating activities of $14.3 million for the same period last fiscal year. The increase in cash provided by operating activities was the result of stronger working capital management.

Net cash used in investing activities was $5.8 million for the three months ended September 30, 2012, compared to net cash used of $58.8 million for the same period last fiscal year. The majority of the change in net cash used in investing activities was the result of the acquisition of Aegis in July 2011 as well as reduced capital spending in the current year.

Net cash used in financing activities for the three months ended September 30, 2012 consisted mostly of $5.9 million of cash used to repurchase Company stock under the approved share repurchase program, somewhat offset by net proceeds on long-term borrowings of $5.0 million. Net cash provided by financing activities during the three months ended September 30, 2011 consisted mostly of net proceeds on long-term borrowings of $5.7 million.

At September 30, 2012, the Company’s credit facility was a $50.0 million unsecured line of credit, which, on October 31, 2012, was expanded to $80.0 million (as noted below). The credit facility has a five-year term through June 2016 and has an interest rate of LIBOR, as defined in the agreement, plus 0.625% to 1.50%. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of September 30, 2012, the Company was in compliance with all financial covenants.

The Company’s Yen denominated line of credit is a 500 million Yen facility that has a five-year term through June 2016 and has an interest rate equal to the LIBOR Rate, as defined in the loan agreement, plus 0.625% to 1.50%. At September 30, 2012 and June 30, 2012, the Company had 300 million Yen borrowed. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of September 30, 2012, the Company was in compliance with all financial covenants.

The Company had aggregate availability of $37.2 million and $42.3 million under its lines of credit as of September 30, 2012 and June 30, 2012, respectively. The amounts available under the Company’s lines of credit are reduced by outstanding letters of credit. As of September 30, 2012 and June 30, 2012, total outstanding letters of credit supported by the credit facilities were $0.9 million.

The weighted average interest rate of total borrowings was 0.89% and 1.01%, respectively, for the three months ended September 30, 2012 and 2011.

22

The Company’s cash position, borrowing capacity and debt obligations for the periods indicated were as follows ($000’s):

	September 30, 2012		June 30, 2012
Cash and cash equivalents	$	152.6	$	134.9
Available borrowing capacity		37.2		42.3
Total debt obligation		17.9		12.8

The Company believes cash flow from operations, existing cash reserves and available borrowing capacity will be sufficient to fund its working capital needs, capital expenditures and internal and external growth objectives for the next twelve months. The Company’s cash and cash equivalent balances are generated and held in numerous locations throughout the world, including amounts held outside the United States. As of September 30, 2012 and June 30, 2012, the Company held approximately $115 million and $97 million, respectively, of cash and cash equivalents outside of the United States. Cash balances held outside the United States could be repatriated to the United States, but, under current law, would potentially be subject to United States federal income taxes, less applicable foreign tax credits. The Company has not recorded deferred income taxes related to undistributed earnings outside of the United States as the earnings of the Company’s foreign subsidiaries are indefinitely reinvested.

On November 1, 2012, the Company, through a merger involving a wholly-owned subsidiary of II-VI, acquired all of the outstanding shares of M Cubed Technologies, Inc. (“M Cubed”), a privately held company with operations in Connecticut and Delaware for approximately $71.4 million, subject to a potential post-closing working capital adjustment that could increase the purchase price by up to $2.5 million.

As noted above, on October 31, 2012, the Company exercised the accordion feature of its existing $50 million unsecured credit facility to increase the size of its credit facility from $50 million to $80 million. Except as described above, the credit facility continues pursuant to its existing terms and conditions. The Company used a portion of its increased available credit facility to finance the acquisition of M Cubed. Total long-term debt of the Company immediately following the acquisition of M Cubed was approximately $82 million.

(1) Variable rate interest obligations are based on the interest rate in place at September 30, 2012.

(2) Includes an obligation for the use of two parcels of land related to PRM. The lease obligation extends through years 2039 and 2056.

(3) A purchase obligation is defined as an agreement to purchase goods or services that is enforceable and legally binding on the Company and that specifies all significant terms, including fixed or minimum quantities to be purchased; minimum or variable price provisions, and the approximate timing of the transaction. These amounts are primarily comprised of open purchase order commitments to vendors for the purchase of supplies and materials.

The $3.0 million gross unrecognized income tax benefit at September 30, 2012 is excluded from the table above. The Company is not able to reasonably estimate the amount by which the liability will increase or decrease over time; however, at this time, the Company does not expect a significant payment related to these obligations within the next year.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Exchange Risks

The Company is exposed to market risks arising from adverse changes in foreign currency exchange rates and interest rates. In the normal course of business, the Company uses a variety of techniques and derivative financial instruments as part of its overall risk management strategy primarily focused on its exposure to the Japanese Yen. No significant changes have occurred in the techniques and instruments used other than those described below.

Changes in the foreign currency exchange rates of these currencies had an immaterial impact on the results of operations for all periods presented.

In the normal course of business, the Company enters into foreign currency forward exchange contracts with its banks. The purpose of these contracts is to hedge ordinary business risks regarding foreign currencies on product sales. Foreign currency exchange contracts are used to limit transactional exposure to changes in currency exchange rates. The Company enters into foreign currency forward contracts that permit it to sell specified amounts of foreign currencies expected to be received from its export sales for pre-established U.S. dollar amounts at specified dates. The forward contracts are denominated in the same foreign currencies in which export sales are denominated. These contracts provide the Company with an economic hedge in which settlement will occur in future periods and which otherwise would expose the Company to foreign currency risk. The Company monitors its positions and the credit ratings of the parties to these contracts. While the Company may be exposed to potential losses due to risk in the event of non-performance by the counterparties to these financial instruments, it does not anticipate such losses. The Company currently has a 500 million Yen revolving credit facility to help minimize the foreign currency exposure in Japan. A change in the interest rate of 1% for this Yen loan would have changed the interest expense by an immaterial amount for the three months ended September 30, 2012. A 10% change in the Yen to dollar exchange rate would have changed revenues in the range from a decrease of $0.7 million to an increase of $0.9 million for the three months ended September 30, 2012.

For II-VI Singapore Pte., Ltd. and its subsidiaries, II-VI Suisse S.a.r.l., PRM and AOFR, the functional currency is the U.S. dollar. Gains and losses on the remeasurement of the local currency financial statements are included in net earnings. Foreign currency remeasurement was immaterial for all periods presented.

For all other foreign subsidiaries, the functional currency is the local currency. Assets and liabilities of those operations are translated into U.S. dollars using period-end exchange rates while income and expenses are translated using the average exchange rates for the reporting period. Translation adjustments are recorded as accumulated other comprehensive income within shareholders’ equity.

Interest Rate Risks

As of September 30, 2012, the total borrowings of $17.9 million were from a line of credit of $3.9 million denominated in Japanese Yen and a line of credit borrowing of $14.0 million denominated in U.S. dollars. As such, the Company is exposed to market risks arising from changes in interest rates. A change in the interest rate of these borrowings of 1% would have had an immaterial impact on the Company’s financial results for the three months ended September 30, 2012.

Commodity Risk

We are exposed to price risks for our tellurium and selenium raw materials. Also, some of our raw materials are sourced from a limited number of suppliers. As a result, we remain exposed to price changes in the raw materials used in such processes. As of September 30, 2012, a 10% decrease in the index price of tellurium and selenium would have caused an additional inventory write-down of approximately $1.1 million, or $0.02 per-share diluted.

Item 4. CONTROLS AND PROCEDURES

The Company’s management evaluated, with the participation of Francis J. Kramer, the Company’s President and Chief Executive Officer, and Craig A. Creaturo, the Company’s Chief Financial Officer and Treasurer, the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this quarterly report on Form 10-Q. The Company’s disclosure controls were designed to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and

24

Exchange Commission. It should be noted that 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, regardless of how remote. However, the controls have been designed to provide reasonable assurance of achieving the controls’ stated goals. Based on that evaluation, Messrs. Kramer and Creaturo concluded that the Company’s disclosure controls and procedures are effective at the reasonable assurance level as of the end of the period covered by this report. No changes in the Company’s internal control over financial reporting were implemented during the Company’s most recently completed fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1A. RISK FACTORS

In addition to the risk factors and other information set forth in this report, carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended June 30, 2012, which could materially affect our business, financial condition or future results. Those risk factors included in our Annual Report on Form 10-K are not the only risks facing the Company. Additional risks and uncertainties not currently known or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Recent Accounting Pronouncements

Note 2. Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update related to impairment testing of indefinite-lived intangible assets. The update simplifies the guidance of testing for potential impairment of indefinite-lived intangible assets other than goodwill. The amendment provides entities the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. An entity electing to perform a qualitative assessment is no longer required to calculate the fair value of an indefinite-lived intangible asset unless the organization determines, based on a qualitative assessment, that it is “more likely than not” (that is, a likelihood of more than 50 percent) that the asset is impaired. The amendments in this update are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements and indefinite-lived intangible asset impairment testing.

In September 2011, the FASB issued an accounting standard update related to goodwill impairment testing. The objective of the accounting standard update is to simplify how entities test goodwill for impairment by permitting an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This update also allows entities an unconditional option to bypass this qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. This accounting standard update is effective for annual and interim goodwill impairment tests performed for fiscal years beginning on or after December 15, 2011, with early adoption permitted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements and goodwill impairment testing.

In June 2011, the FASB issued changes to the presentation of comprehensive income that require entities to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity is no longer permitted. This guidance, with retrospective application, was adopted by the Company in the first quarter of fiscal year 2013. Other than the change in presentation, these changes have had no impact on the consolidated financial statements and the calculation and presentation of earnings per share.

In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended June 30, 2012. The consolidated results of operations for the three months ended September 30, 2012 are not necessarily indicative of the results to be expected for the full fiscal year. The June 30, 2012 Condensed Consolidated Balance Sheet information was derived from the Company’s audited financial statements.

Effective July 1, 2012, the Company changed its reportable segments in accordance with how the Company’s chief operating decision maker receives and reviews financial information. Effective July 1, 2012, VLOC Incorporated (“VLOC”) has been included in the Military & Materials operating segment for financial reporting purposes.

Note 15. Subsequent Events

On November 1, 2012, the Company, through a merger involving a wholly-owned subsidiary of II-VI, acquired all of the outstanding shares of M Cubed Technologies, Inc. (“M Cubed”), a privately held company with operations in Connecticut and Delaware for approximately $71.4 million, subject to a potential post-closing working capital adjustment that could increase the purchase price by up to $2.5 million. M Cubed develops advanced ceramic materials and precision motion control products addressing the semiconductor, crystal display, industrial and defense markets. The final purchase price will be subject to customary closing adjustments, including working capital adjustments. The results for the three months ended September 30, 2012 do not include any operating results of M Cubed, but do include certain transaction-related expenses attributable to the acquisition of M Cubed of approximately $0.5 million, pre-tax, which are required to be expensed under current accounting standards. Due to the timing of the acquisition of M Cubed, the final purchase price allocation and related accounting for M Cubed was not available as of the filing date of this Quarterly Report on Form 10-Q. This information will be disclosed in future filings.

On October 31, 2012, the Company exercised the accordion feature of its existing $50 million unsecured credit facility to increase the size of its credit facility from $50 million to $80 million. Except as described above, the credit facility continues pursuant to its existing terms and conditions. The Company used a portion of its increased available credit facility to finance the acquisition of M Cubed. Total long-term debt of the Company immediately following the acquisition of M Cubed was approximately $82 million.

Segment Reporting

Note 10. Segment Reporting

The Company reports its business segments using the “management approach” model for segment reporting. The Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing performance.

Effective July 1, 2012, the Company’s VLOC business unit has been included in the Military & Materials operating segment for financial reporting purposes in accordance with how the Company’s chief operating decision maker receives and reviews financial information. Prior to July 1, 2012, VLOC was included in the Near-Infrared Optics operating segment. The Company has revised the consolidated segment information for all periods presented in this Form 10-Q to reflect this reclassification.

The Company has four reportable segments. The Company’s chief operating decision maker receives and reviews financial information in this format. The Company evaluates business segment performance based upon reported business segment earnings, which is defined as earnings before income taxes, interest and other income or expense. The segments are managed separately due to the production requirements and facilities that are unique to each segment. The Company had the following reportable segments at September 30, 2012: (i) Infrared Optics, which consists of the Company’s infrared optics and material products businesses, HIGHYAG Lasertechnologie GmbH (“HIGHYAG”) and certain remaining corporate activities, primarily corporate assets and capital expenditures; (ii) Near-Infrared Optics, which consists of Photop, Aegis Lightwave, Inc. and AOFR; (iii) Military & Materials, which consists of the Company’s Exotic Electro-Optics, Inc. (“EEO”) subsidiary, VLOC, Max Levy Autograph (“MLA”), and Pacific Rare Speciality Metals & Chemicals, Inc. (“PRM”); and (iv) Advanced Products Group, which is comprised of the Company’s Marlow Industries, Inc. (“Marlow”) subsidiary, the Wide Bandgap Materials Group (“WBG”) and the Worldwide Materials Group (“WMG”); WMG is responsible for the corporate research and development activities.

The Infrared Optics segment is divided into geographic locations in the U.S., Singapore, China, Germany, Switzerland, Japan, Belgium, the U.K. and Italy. The Infrared Optics segment is directed by a general manager, while each geographic location is also directed by a general manager, and is further divided into production and administrative units that are directed by managers. The Infrared Optics segment designs, manufactures and markets optical and electro-optical components and materials sold under the II-VI brand name and used primarily in high-power CO₂ lasers. The Infrared Optics segment also manufactures fiber-delivered beam delivery systems and processing tools for industrial lasers sold under the HIGHYAG brand name.

The Near-Infrared Optics segment is located in the U.S., China, Vietnam, Australia, Germany, Japan, the U.K., Italy and Hong Kong. The Near-Infrared Optics segment is directed by a Corporate Executive Vice President and is further divided into production and administrative units that are directed by managers. The Near-Infrared Optics segment manufactures crystal materials, optics, microchip lasers and opto-electronic modules for use in optical communication networks and other diverse consumer and commercial applications sold under the Photop brand name and manufactures tunable optical devices and couplers and combiners required for high speed optical networks sold under the Aegis and AOFR brand names, respectively.

The Military & Materials segment is located in the U.S. and the Philippines. The Military & Materials segment is directed by a Corporate Vice President, while each geographic location is directed by a general manager. The Military & Materials segment is further divided into production and administrative units that are directed by managers. The Military & Materials segment designs, manufactures and markets infrared products for military applications under the EEO brand name, refines specialty metals and rare earth elements, primarily selenium and tellurium, under the PRM brand name, and manufactures and markets micro-fine conductive mesh patterns for optical, mechanical, and ceramic components for applications under the MLA brand name. The Military & Materials segment also designs, manufactures and markets near-infrared and visible-light products for military applications and laser gain material and products for solid-state yttrium aluminum garnet (“YAG”) lasers, yttrium lithium fluoride (“YLF”) lasers and Ultra-Violet (“UV”) Filter components sold under the VLOC brand name.

The Advanced Products Group is located in the U.S., Vietnam, Japan, China and Germany and is directed by a Corporate Executive Vice President. In the Advanced Products Group segment, Marlow designs and manufactures thermoelectric cooling and power generation solutions for use in defense and space, optical communications, medical, consumer and industrial markets. WBG manufactures and markets single crystal silicon carbide substrates for use in solid-state lighting, wireless infrastructure, radio frequency (“RF”) electronics and power switching industries. WMG directs the corporate research and development initiatives.

The accounting policies of the segments are the same as those of the Company. All of the Company’s corporate expenses are allocated to the segments. The Company evaluates segment performance based upon reported segment earnings, which is defined as earnings before income taxes, interest and other income or expense. Inter-segment sales and transfers have been eliminated.

The following tables summarize selected financial information of the Company’s operations by segment:

Share-Based Compensation

3 Months Ended

Sep. 30, 2012

Share-Based Compensation

Note 11. Share-Based Compensation

The Board of Directors adopted the II-VI Incorporated 2009 Omnibus Incentive Plan (the “Plan”) which was approved by the shareholders of the Company. The Plan provides for the grant of non-qualified stock options, stock appreciation rights, restricted share awards, restricted share units, deferred share awards, performance share awards and performance share units to employees, officers, directors and consultants of the Company. The Company records share-based compensation expense for these awards in accordance with U.S. GAAP, which requires the recognition of the fair value of share-based compensation in net earnings. The Company recognizes the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period.

During the three months ended September 30, 2012 and 2011, the Company recorded $3.6 million and $4.6 million, respectively, of share-based compensation expense in its Condensed Consolidated Statements of Earnings. The share-based compensation expense is allocated approximately 20% to cost of goods sold and 80% to selling, general and administrative expense in the Condensed Consolidated Statements of Earnings, based on the employee classification of the grantees.

Stock Options and Stock Appreciation Rights:

The Company utilizes the Black-Scholes valuation model for estimating the fair value of these awards. During the three months ended September 30, 2012 and 2011, the weighted-average fair values of awards granted under the Plan were $8.49 and $9.33 per award, respectively, using the following assumptions:

	Three Months Ended September 30, 2012			Three Months Ended September 30, 2011
Risk free interest rate		0.93	%		1.07	%
Expected volatility		49	%		59	%
Expected life of options		5.65 years			5.51 years
Dividend yield		None			None

The risk-free interest rate is derived from the average U.S. Treasury Note rate during the period, which approximates the rate in effect at the time of grant related to the expected life of the awards. The risk free interest rate shown above is the weighted average rate for all awards granted during the fiscal year. Expected volatility is based on the historical volatility of the Company’s Common Stock over the period commensurate with the expected life of the awards. The expected life calculation is based on the observed time to post-vesting exercise and/or forfeitures of awards by our employees. The dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no intention to pay cash dividends in the future. The estimated annualized forfeitures are based on the Company’s historical experience of award cancellations pre-vesting and are estimated at a rate of 16%. The Company will record additional expense in future periods if the actual forfeiture rate is lower than estimated, and will adjust expense in future periods if the actual forfeitures are higher than estimated.

Included in the $3.6 million and $4.6 million of share-based compensation expense for the three months ended September 30, 2012 and 2011, respectively, was $1.6 million and $2.9 million of share-based compensation expense related to these awards.

Restricted Share Awards and Restricted Share Units:

The restricted share awards and units compensation expense was calculated based on the number of shares or units expected to be earned by the grantee multiplied by the stock price at the date of grant and is being recognized over the vesting period. Generally, the restricted share awards and units have a three year cliff-vesting provision and an estimated forfeiture rate of 7.5%. Included in the $3.6 million and $4.6 million of share-based compensation expense for the three months ended September 30, 2012 and 2011, respectively, was $1.1 million and $0.8 million, respectively, of share-based compensation expense related to restricted share awards and units.

Performance Share Awards and Performance Share Units:

The Compensation Committee of the Board of Directors of the Company has granted certain named executive officers and employees performance share awards and units under the Plan. As of September 30, 2012, the Company had outstanding grants covering performance periods ranging from 24 to 48 months. These awards are intended to provide continuing emphasis on specified financial performance goals that the Company considers important contributors to long-term shareholder value. These awards are payable only if the Company achieves specified levels of financial performance during the performance periods.

In conjunction with the Company’s acquisition of Photop, the Compensation Committee established both a short-term and long-term performance and retention program under the Plan for certain Photop employees. As of September 30, 2012, a portion of this long-term performance and retention program was still outstanding, covering a performance period from January 1, 2012 to December 31, 2012. The remaining long-term retention and performance awards are payable only if Photop achieves the levels of revenue and earnings specified for the outstanding performance period as well as certain other pre-established non-financial performance targets.

The performance share awards and units compensation expense is calculated based on the estimated number of shares or units expected to be earned multiplied by the stock price at the date of grant. Included in the $3.6 million and $4.6 million of share-based compensation expense for each of the three months ended September 30, 2012 and 2011, respectively, was $0.9 million of share-based compensation expense related to performance share awards and units.

The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

• Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

• Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

• Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. At September 30, 2012 and 2011, the Company had foreign currency forward contracts in Japanese Yen recorded at fair value. The fair values of these instruments were measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk and restrictions and other terms specific to the contracts. These contracts are recorded in Other accrued liabilities or Prepaid and other current assets in the Company’s Condensed Consolidated Balance Sheets. The change in the fair value of these contracts for the three months ended September 30, 2012 and 2011 was insignificant.

Income Taxes

Note 8. Income Taxes

The Company’s year-to-date effective income tax rate at September 30, 2012 and 2011 was 24.2% and 23.9%, respectively. The variations between the Company’s effective tax rates and the U.S. statutory rate of 35.0% were primarily due to the consolidation of the Company’s foreign operations, which are subject to income taxes at lower statutory rates. A change in the mix of pretax income from these various tax jurisdictions could have a material impact on the Company’s effective tax rate.

U.S. GAAP clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of September 30, 2012 and June 30, 2012, the gross unrecognized income tax benefit was $3.0 million and $2.9 million, respectively. The Company has classified the uncertain tax positions as non-current income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, substantially all of the gross unrecognized tax benefits at September 30, 2012 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision on the Condensed Consolidated Statements of Earnings. The amount of accrued interest and penalties included in the $3.0 million and $2.9 million of gross unrecognized income tax benefit at September 30, 2012 and June 30, 2012 was immaterial. Fiscal years 2010 to 2012 remain open to examination by the United States Internal Revenue Service, fiscal years 2008 to 2012 remain open to examination by certain state jurisdictions, and fiscal years 2005 to 2012 remain open to examination by certain foreign taxing jurisdictions.

Goodwill and Other Intangible Assets

Note 6. Goodwill and Other Intangible Assets

Changes in the carrying amount of goodwill are as follows ($000):

	Three Months Ended September 30, 2012
	Infrared Optics		Near-Infrared Optics			Military & Materials		Advanced Products Group		Total
Balance – beginning of period	$	9,612	$	48,496		$	12,326	$	10,314	$	80,748

Balance – end of period	$	9,695	$	48,413		$	12,326	$	10,314	$	80,748

The Company reviews the recoverability of goodwill at least annually and any time business conditions indicate a potential change in recoverability. The measurement of a potential impairment begins with comparing the current fair value of the Company’s reporting units to the recorded value (including goodwill). The Company uses a discounted cash flow model (“DCF model”) and a market analysis to determine the current fair value of its reporting units. A number of significant assumptions and estimates are involved in estimating the forecasted cash flows used in the DCF model, including markets and market shares, sales volume and pricing, costs to produce, working capital changes and income tax rates. Management considers historical experience and all available information at the time the fair values of the reporting units are estimated. However, actual fair values that could be realized could differ from those used to evaluate the impairment of goodwill.

The gross carrying amount and accumulated amortization of the Company’s intangible assets other than goodwill as of September 30, 2012 and June 30, 2012 was as follows ($000):

	September 30, 2012							June 30, 2012
	Gross Carrying Amount		Accumulated Amortization			Net Book Value		Gross Carrying Amount		Accumulated Amortization			Net Book Value
Patents	$	21,854	$	(8,078	)	$	13,776	$	21,856	$	(7,640	)	$	14,216

Total	$	62,266	$	(19,296	)	$	42,970	$	62,213	$	(18,199	)	$	44,014

Amortization expense recorded on these intangible assets was $1.1 million and $1.0 million, for the three months ended September 30, 2012 and 2011, respectively. The patents are being amortized over a range of 120 to 240 months with a weighted average remaining life of approximately 121 months. The customer lists are being amortized over approximately 120 months with a weighted average remaining life of approximately 97 months. The gross carrying amount of trademarks includes $11.4 million of acquired trade names resulting from past acquisitions. These trade names have indefinite lives and are not amortized but tested annually for impairment or more frequently if a triggering event occurs. Included in the gross carrying amount and accumulated amortization of the Company’s intangible assets is the effect of foreign currency translation on that portion of the intangible assets relating to the Company’s German subsidiaries, Photop Technologies, Inc. (“Photop”) and AOFR Pty. Ltd. (“AOFR”).

At September 30, 2012, the estimated amortization expense for existing intangible assets for each of the five succeeding fiscal years is as follows ($000):

Year Ending June 30,
Remaining 2013	$	3,163
2014		3,744
2015		3,479
