Quantum Reports Fourth Quarter and Fiscal 2023 Results
Revenue Increases 10.7% Year-over-Year to $412.8 Million
SAN JOSE, Calif. — June 6, 2023 — Quantum Corporation (NASDAQ: QMCO) announced today financial results for its fiscal fourth quarter and fiscal year ended March 31, 2023.
Fourth Quarter Fiscal 2023 Financial Summary
•Revenue increased 10.7% year-over-year to $105.3 million
•GAAP net loss was $13.6 million, or ($0.15) per share
•Annual recurring revenue was $156 million
•Subscription ARR was up 81% year-over-year at $13.4 million
•Adjusted non-GAAP net loss was $3.7 million, or ($0.04) per share
•Adjusted EBITDA was $1.0 million
“We ended fiscal 2023 with positive momentum as fourth quarter revenue and EBITDA results exceeded our guidance on improved operational execution,” said Jamie Lerner, Chairman and CEO of Quantum. “We also began to see increased stability across the supply chain through greater availability of parts and lower inflationary costs. Additionally, our focused efforts to improve working capital and decrease inventory yielded positive results as we continue to carefully manage cash flow.”
“Having weathered a macro environment marked by a global pandemic, supply chain challenges, and disruptive inflation, we are beginning to see signs of improvement across our business. As we continue to chart our business transformation for improved performance, subsequent to the end of the fourth quarter, we implemented a global efficiency plan that includes a cost reduction action which we expect to yield approximately $14 million in annualized savings by the end of fiscal year 2025, with a payback of under six months. Also, to support greater operational flexibility in the near term, we proactively secured an additional $15 million of liquidity and greater covenant flexibility from our current lenders to capitalize on the cost savings initiative and position the company for growth as we bring our recent product innovations to market.”
“These actions, combined with our focus on the fastest-growing storage market segment and our investment in sales and marketing to drive future growth, further bolster our business transformation strategy. Although we anticipate the first fiscal quarter to be seasonally lower, we expect a resumption of revenue rotation to higher margin products and EBITDA expansion throughout the remainder of the year.”

NON-GAAP FINANCIAL MEASURES
To provide investors with additional information regarding our financial results, we have presented certain non-GAAP financial measures in this press release, including non-GAAP adjusted net loss, adjusted EBITDA, non-GAAP gross profit and non-GAAP operational expenses.
Adjusted EBITDA is a non-GAAP financial measure defined by us as net loss before interest expense, net, provision for income taxes, depreciation and amortization expense, stock-based compensation expense, restructuring charges, and other non-recurring expenses.
“GAAP net loss” as referred to in this press release represents “Net loss attributable to common stockholders”. Non-GAAP adjusted net income (loss) is a non-GAAP financial measure defined by us as net loss before restructuring charges, stock-based compensation expense, and other non-recurring (income) expenses. We calculate adjusted net income (Loss) per basic and diluted share using the above-referenced definition of adjusted net income (Loss).
We have provided below reconciliations of adjusted EBITDA to adjusted net income (loss), non-GAAP gross profit and non-GAAP operational expenses, to the most directly comparable U.S. GAAP financial measures. We have presented adjusted EBITDA because it is a key measure used by our management and the board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short and long-term operating plans. In particular, we believe that the exclusion of the amounts eliminated in calculating adjusted EBITDA can provide a useful measure for period-to-period comparisons of our core business performance. For example, in the quarter ended September 30, 2022, we have excluded a large inventory reserve provision caused by global supply chain disruptions since the start of the pandemic and the longer associated lead times that resulted in older generation products being displaced by next-generation solutions. We do not believe an inventory adjustment of this magnitude is reasonably likely to reoccur in the foreseeable future and do not believe it is indicative of our ongoing operations; accordingly, we have excluded its impact from our non-GAAP results. We believe adjusted net income (loss) and adjusted net income (loss) per basic and diluted share serve as appropriate measures to be used in evaluating the performance of our business and help our investors better compare our operating performance over multiple periods. Accordingly, we believe that the use of non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and our board of directors.
Our use of non-GAAP financial measures have limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these limitations are as follows:
•Although depreciation and amortization expense are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;
•Adjusted EBITDA does not reflect: (1) interest and tax payments that may represent a reduction in cash available to us; (2) capital expenditures, future requirements for capital expenditures or contractual commitments; (3) changes in, or cash requirements for, working capital needs; (4) the potentially dilutive impact of stock-based compensation expense; (5) potential future costs related to our long-term debt; (6) potential future restructuring expenses; (7) potential future costs related to business acquisitions; (8) gain (loss) on debt extinguishment, (9) and acquisition-related amortization of intangibles assets from business combinations, (10) deemed dividend related to warrants, or (11) manufacturing inventory provisions.
•Adjusted net income (loss) does not reflect: (1) potential future restructuring activities; (2) the potentially dilutive impact of stock-based compensation expense; (3) potential future costs related to our long-term debt; (4) potential future costs related to business acquisitions; (5) gain (loss) on debt extinguishment; (6) acquisition-related amortization of intangibles assets from business combinations; (7) deemed dividend related to warrants; or (8) manufacturing inventory provisions.
Other companies, including companies in our industry, may calculate non-GAAP financial measures differently, which reduces its usefulness as a comparative measure. Because of these and other limitations, you should consider adjusted EBITDA and adjusted net income (loss) along with other U.S. GAAP-based financial performance measures, including various cash flow metrics and our U.S. GAAP financial results.

In addition, this press release includes non-GAAP adjusted earnings or net loss per share and adjusted EBITDA, each a non-GAAP measure used to describe our expected performance. We have not presented a reconciliation of these non-GAAP measures to our most comparable GAAP financial measures, because the reconciliation could not be prepared without unreasonable effort. The information necessary to prepare the reconciliations is not available on a forward-looking basis and cannot be accurately predicted. The unavailable information could have a significant impact on the calculation of the comparable GAAP financial measure.
The tables below reconcile the non-GAAP financial measures of adjusted EBITDA, net income, diluted EPS, operating expenses and gross margin with the most directly comparable GAAP financial measures (in thousands, unaudited).
