“Quantum delivered strong fourth quarter results with revenue of $78 million, representing 27% growth year-over-year. This performance reflects robust demand for our tiered storage solutions as the proliferation of AI-driven data rapidly reshapes the industry and enterprise storage infrastructure requirements,” commented Hugues Meyrath, CEO of Quantum. “With the exploding volume of data, rising storage costs, and increasing power constraints, organizations are rethinking how they store, manage, and protect their most valuable assets. Quantum is uniquely positioned to help customers reduce their dependence on constrained, high-cost components with differentiated, power-efficient storage solutions that provide long-term data resilience.

“As we look to fiscal year 2027, Quantum is operating from a position of renewed strength and expanding strategic relevance. Over the past year, we have transformed our business by significantly lowering our cost structure, while also sharpening our sales execution and go-to-market strategy. And more recently, we successfully completed a series of transactions that eliminated our outstanding debt and added cash to the balance sheet in support of our growth initiatives. Although supply chain constraints remain an industry-wide challenge, we are seeing clear momentum in our pipeline and backlog. We remain committed to executing with discipline as we continue to drive toward long-term sustainable growth, margin expansion and value creation for our shareholders.”

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 operating expenses.

Non-GAAP adjusted operating expenses is a non-GAAP financial measure defined by us as GAAP operating expenses with stock-based compensation expense, restructuring charges, amortization of acquisition related intangible assets and non-recurring project costs removed.

We have provided below a reconciliation of non-GAAP adjusted operating expenses, to the most directly comparable U.S. GAAP financial measure. We believe that the exclusion of the amounts eliminated in this calculation can provide a useful measure for period-to-period comparisons of our core business performance. 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.

 

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 non-GAAP adjusted operating expenses along with other U.S. GAAP-based financial performance measures, including various cash flow metrics and our U.S. GAAP financial results.
