Weak moat
How hard Data Storage's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.
Cash operating profit has been a median -3.8% of total assets over 10 years.
Gross margin has been a median 41.5%, moving by 3.7 percentage points (standard deviation) across 10 years.
Operating margin has been a median -3.7%; its worst year was -309.2%.
Free cash flow was positive in 4 of 6 years, at a median 5.2% of revenue.
The diluted share count fell 92.1% over five years; stock-based pay has been a median 1.9% of revenue.
AI disruption exposure: High. In this industry, the core product is information work that AI systems increasingly perform. The score above includes a 15-point deduction for that exposure (52 before it).
Next results: November 16, 2026, before the open. Analysts expect revenue of $500000 and EPS of $0.00 (range $0.00 to $0.00) for the quarter.
