II-VI Incorporated Reports Fiscal 2021 Second Quarter Results

Record Quarterly Revenue of $786.6 million
Record Backlog of $1.08 billion
Record Cash from Operations of $221 million and Record Free Cash Flow $175.8 million¹
Quarterly GAAP Operating Income of $118.7 million and GAAP EPS of $0.73
Quarterly Non-GAAP Operating Income of $173.0 million and Non-GAAP EPS of $1.08
December 31, 2020 net debt leverage ratio of 0.9x, reduced from 1.3x at September 30, 2020²

PITTSBURGH, Feb. 09, 2021 (GLOBE NEWSWIRE) -- II-VI Incorporated (Nasdaq:IIVI) ("II-VI," “We” or the "Company") today reported results for its fiscal 2021 second quarter ended December 31, 2020.

“This quarter’s record results are a prime example of the successful execution of our strategy. Our book to bill ratio was 1.17 for the quarter and was 1.12 on a rolling twelve-month basis. Our revenue growth in Q2 FY21 was 18% over Q2 FY20. We continued to gain share in 3D sensing, growing our revenue over 200% compared to last year and over 140% sequentially. We increased our volume shipments into multiple end customers and applications, in front facing as well as world facing configurations,” said Dr. Vincent D. (Chuck) Mattera, Jr.

Dr. Mattera continued, “We are well ahead of our plan to achieve our 3-year, $150M total synergy target from the Finisar acquisition. Our run rate synergies already exceed $100M as a result of our integration work over the past 15 months. We are now on track to achieve our $150M total synergy target in 24 months, 12 months ahead of schedule, and we are now increasing our 3-year total synergy target to $200M. This work is contributing to our strengthening margins and strong cash flow. Our cash flow from operations in Q2 was an all-time record at $221 million and our net debt leverage ratio reduced to 0.9x. With all of our target markets strengthening, we look forward to the exciting opportunities ahead of us in the second half of the FY21 and beyond.”

_________________

¹ Free cash flow of $175.8M is defined as cash flow from operations of $221.3M less capital expenditures of $45.5M for the three months ended December 31, 2020.
²The net debt leverage ratio is calculated in accordance with the terms of the Credit Agreement.

See Table 4 for the Reconciliation of GAAP measures to non-GAAP measures.

Outlook

The outlook for the third fiscal quarter ending March 30, 2021 is revenue of $760 million to $780 million and earnings per diluted share on a non-GAAP basis of $0.81 to $0.91. This is at today’s exchange rate and today’s estimated tax impact of 19%. Both of these are subject to variability. For the non-GAAP earnings per share, we added back to the GAAP earnings pre-tax amounts of $21 million in amortization, $22 million in share-based compensation, and $2 million in transaction costs. Non-GAAP adjustments are by their nature highly volatile and we have low visibility as to the range that may be incurred in the future.

Forward-looking Statements

This press release contains forward-looking statements relating to future events and expectations that are based on certain assumptions and contingencies. The forward-looking statements are made pursuant to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995 and relate to the Company’s performance on a going-forward basis. The forward-looking statements in this press release involve risks and uncertainties, which could cause actual results, performance or trends to differ materially from those expressed in the forward-looking statements herein or in previous disclosures.

The Company believes that all forward-looking statements made by it in this release have a reasonable basis, but there can be no assurance that management’s expectations, beliefs or projections as expressed in the forward-looking statements will actually occur or prove to be correct. In addition to general industry and global economic conditions, factors that could cause actual results to differ materially from those discussed in the forward-looking statements in this press release include, but are not limited to: (i) the failure of any one or more of the assumptions stated above to prove to be correct; (ii) the risks relating to forward-looking statements and other “Risk Factors” discussed in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2020; (iii) the purchasing patterns of customers and end-users; (iv) the timely release of new products, and acceptance of such new products by the market; (v) the introduction of new products by competitors and other competitive responses; (vi) the Company’s ability to integrate recently acquired businesses and realize synergies, cost savings and opportunities for growth in connection therewith, together with the risks, costs and uncertainties associated with such acquisitions and integration efforts; (vii) the Company’s ability to devise and execute strategies to respond to market conditions; and/or (viii) the risks of business and economic disruption related to the currently ongoing COVID-19 outbreak and any other worldwide health epidemics and outbreaks that may arise. The Company disclaims any obligation to update information contained in these forward-looking statements whether as a result of new information, future events or developments, or otherwise.

Use of Non-GAAP Financial Measures

The Company has disclosed financial measurements in this press release that present financial information considered to be non-GAAP financial measures. These measurements are not a substitute for GAAP measurements, although the Company's management uses these measurements as an aid in monitoring the Company's on-going financial performance. The non-GAAP net earnings, the non-GAAP earnings per share, the non-GAAP operating income, the non-GAAP gross profit, the non-GAAP internal research and development, the non-GAAP selling, general and administration, the non-GAAP interest and other (income) expense, and the non-GAAP income tax (benefit), measure earnings and operating income (loss), respectively, excluding non-recurring or unusual items that are considered by management to be outside the Company’s standard operation and excluding certain non-cash items. EBITDA is an adjusted non-GAAP financial measurement that is considered by management to be useful in measuring the profitability between companies within the industry by reflecting operating results of the Company excluding non-operating factors. There are limitations associated with the use of non-GAAP financial measures, including that such measures may not be entirely comparable to similarly titled measures used by other companies, due to potential differences among calculation methodologies. Thus, there can be no assurance whether (i) items excluded from the non-GAAP financial measures will occur in the future or (ii) there will be cash costs associated with items excluded from the non-GAAP financial measures. The Company compensates for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by providing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures. Investors should consider adjusted measures in addition to, and not as a substitute for, or superior to, financial performance measures prepared in accordance with GAAP.
