EMCORE Reports Fiscal 2022 Fourth Quarter Results

ALHAMBRA, CA, December 20, 2022 – EMCORE Corporation (Nasdaq: EMKR), a leading provider of advanced mixed-signal products that serve the aerospace and defense, communications, and sensing markets, today announced results for the fiscal 2022 fourth quarter (4Q22) ended September 30, 2022. Management will host a conference call to discuss 4Q22 financial and business results today at 5:00 p.m. Eastern Time (ET).

For 4Q22, EMCORE’s consolidated revenue was $25.6 million, comprised of $21.0 million from the Aerospace and Defense (A&D) segment and $4.6 million from the Broadband segment. Net loss was $16.9 million and $10.9 million on a GAAP and non-GAAP basis, respectively. Adjusted EBITDA was negative $9.4 million. Please refer to the schedules at the end of this press release for GAAP to non-GAAP reconciliations and other information related to non-GAAP financial measures.

“4Q22 represents the beginning of a new era for EMCORE. We closed the acquisition of the Inertial Navigation product lines from KVH Industries which, in combination with the Space & Navigation acquisition the quarter before, and existing QMEMS and FOG products, creates the world’s largest independent1 provider of Inertial Navigation solutions. The strength of the combined larger product portfolio enhances our ability to serve key A&D customers in this $3 billion plus market,” said Jeff Rittichier, President and Chief Executive Officer of EMCORE. “A&D accounted for over 80% of the top-line in 4Q22, and while A&D gross margin was adversely impacted by integration-related and other items during the quarter, we have been working diligently on a re-organization initiative to move us closer to operating as one cohesive Inertial Navigation business and to profitability. Additionally, we recently completed the sale/leaseback of the Tinley Park property, adding $10.3 million in cash to our balance sheet in December.”

Aerospace and Defense Segment

For Q422, A&D’s sequential-quarter revenue increase was driven primarily by the addition of the Inertial Navigation product line acquired from KVH Industries, Inc. on August 9, 2022. A&D segment gross margin decreased primarily as a result of numerous factors related to the transition of newly acquired operations in Budd Lake, NJ and Tinley Park, IL as well as QMEMS inventory valuation charges during the quarter.

1All sales are to unaffiliated third-party customers.

(a) Please refer to the schedules at the end of this press release for GAAP to non-GAAP reconciliations and other information related to non-GAAP financial measures.

Broadband Segment

For Q422, Broadband’s sequential-quarter revenue decrease was primarily due to a decline in CATV revenue. Broadband segment gross margin decreased primarily as a result of the lower revenue and higher under-absorption of fixed overhead. R&D expense increased due to higher product development expenses associated with Chips and Sensing products.

Use of Non-GAAP Financial Measures

The Company conforms to U.S. Generally Accepted Accounting Principles (“GAAP”) in the preparation of its financial statements. We disclose supplemental non-GAAP earnings measures for gross margin, operating expenses, research and development expenses, operating margin, and net loss, as well as adjusted EBITDA.

Management believes these supplemental non-GAAP measures reflect the Company’s core ongoing operating performance and facilitates comparisons across reporting periods. The Company uses these measures when evaluating its financial results and for planning and forecasting of future periods. We believe that these supplemental non-GAAP measures are also useful to investors in assessing our operating performance. While we believe in the usefulness of these supplemental non-GAAP measures, there are limitations. Our non-GAAP measures may not be reported by other companies in our industry and/or may not be directly comparable to similarly titled measures of other companies due to potential differences in calculation. We compensate for these limitations by using these non-GAAP measures as a supplement to GAAP and by providing the reconciliations to the most comparable GAAP measure.

The schedules at the end of this press release reconcile the Company’s non-GAAP measures to the most directly comparable GAAP measure. The adjustments share one or more of the following characteristics: they are unusual and the Company does not expect them to recur in the ordinary course of its business, they do not involve the expenditure of cash, they are unrelated to the ongoing operation of the business in the ordinary course, or their magnitude and timing is largely outside of the Company’s control. For all reporting periods disclosed, the Company has applied consistent rationale, method, and adjustments in reconciling non-GAAP measures to the most directly comparable GAAP measure.

Non-GAAP measures are not in accordance with or an alternative to GAAP, nor are they meant to be considered in isolation or as a substitute for comparable GAAP measures. Our disclosures of these measures should be read only in conjunction with our financial statements prepared in accordance with GAAP. Non-GAAP measures should not be viewed as a substitute for the Company’s GAAP results.

Such forward-looking statements include, in particular, projections about our future results, including growth expectations in the A&D segment, expected revenue from our recent acquisitions of the Space & Navigation business of L3 Harris Technologies, Inc. and the inertial navigation business of KVH Industries, Inc., and statements about our future results of operations and financial position, plans, strategies, business prospects, changes, and trends in our business and the markets in which we operate.

Forward-looking statements are based on certain assumptions and analysis made in light of our experience and perception of historical trends, current conditions, and expected future developments as well as other factors that we believe are appropriate under the circumstances. While these statements represent our judgment on what the future may hold, and we believe these judgments are reasonable, these statements are not guarantees of any events or financial results. All forward-looking statements in this press release are made as of the date hereof, based on information available to us as of the date hereof, and subsequent facts or circumstances may contradict, obviate, undermine, or otherwise fail to support or substantiate such statements. We caution you not to rely on these statements without also considering the risks and uncertainties associated with these statements and our business that are addressed in our filings with the Securities and Exchange Commission (“SEC”) that are available on the SEC’s web site located at www.sec.gov, including the sections entitled “Risk Factors” in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q. Certain information included in this press release may supersede or supplement forward-looking statements in our other Exchange Act reports filed with the SEC. We do not intend to update any forward-looking statement to conform such statements to actual results or to changes in our expectations, except as required by applicable law or regulation.
