Winston Score History

The full picture

Optimum Power Services (trading as OPT-Sciences Corporation) is a small aerospace and defense company that provides technical services and engineering solutions to government and military customers. The company focuses on areas such as test and evaluation, systems engineering, and scientific research support, primarily serving agencies within the U.S. Department of Defense. It operates in a niche corner of the defense services industry, competing alongside larger government contractors.

The company earns revenue mainly through government contracts, which typically involve fixed-price or cost-reimbursement arrangements tied to specific projects or programs. It operates almost entirely within the United States, and its small market cap reflects its position as a micro-cap defense services firm. Its main competitive advantage is its specialized technical expertise, which creates some switching costs once embedded in long-term government programs. The biggest risk the company faces is contract concentration — losing one or two key government contracts could significantly hurt its revenue and profitability.

Growth + cash flow

OPT-Sciences Corporation is a rare growth stock that's already generating positive cash flow while growing at 15%. The Winston Score doesn't fully credit this transition from "burner" to "earner."

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
