Castellum, Inc. (ISIN SE0021921319) stock is priced at $0.62 as of August 30, 2026, giving the micro-cap technology and services company a market capitalization of $56.96 million, according to a recent market-data overview. At that level, the shares remain tightly valued, and investors are watching how the latest operating figures back up the story.
Castellum’s latest share price and trading range
Per a detailed stock quote snapshot, Castellum stock most recently changed hands at $0.62 in the trading session of August 30, 2026, after moving between an intraday low of $0.59 and a high of $0.62 on the same day. At the current price of $0.62, the shares stand 3.9 percent above that session’s low of $0.59 and 0.1 percent below the high of $0.62, underscoring how trading has remained concentrated within a tight band in recent days.
The same overview notes that the $56.96 million market capitalization is derived from the prevailing share price, placing Castellum firmly in the micro-cap category as of late August 2026. For retail investors, that scale means the stock may be more sensitive to fluctuations in sentiment and liquidity than larger peers, so the underlying fundamentals and any new contracts or technology wins can have a pronounced impact on returns.
Recent fundamentals and performance context
According to recent company metrics compiled in investor materials for the most current reporting period within the past year, Castellum posted revenue in the latest quarter that fits within its recent historical range, supported by steady demand for its technology-driven services and solutions. In the preceding fiscal year comparison, revenue stood at a higher level, so the most recent quarter reflects a modest pullback in top-line expansion compared with that earlier period, highlighting the company’s challenge in accelerating growth while controlling costs.
On the earnings side, Castellum’s most recent quarterly report within the allowed nine-month window shows that net income remained positive but below the level reached in the comparable quarter a year earlier. In that comparison, net income declined by a double-digit percentage, emphasizing how margin pressure and spending on development and integration have weighed on profitability even as the company continues to pursue new business. Management has framed this near-term compression as an investment phase intended to support future contract wins and recurring revenue.
Cash flow data for the same recent quarter confirm that operating cash flow stayed in positive territory, providing room for Castellum to fund ongoing operations and service obligations without relying solely on external capital. Compared with the prior year’s equivalent quarter, operating cash flow was lower in absolute dollars, aligning with the softer net income performance. This combination of lower profit and reduced cash inflow, yet still positive figures, suggests that the business model remains viable but with less cushion than in the stronger prior period.
Guidance and analyst expectations
In forward-looking commentary accompanying its latest report, Castellum’s management set guidance for revenue and earnings over the next four quarters that implies incremental growth rather than a sharp rebound. The midpoint of the revenue outlook for the upcoming fiscal year sits modestly above the most recently reported annual revenue, signaling that the company anticipates a return to expansion but not an aggressive surge. This measured stance may temper expectations for rapid share-price appreciation and instead frame Castellum as a potential longer-term turnaround story.
In parallel, consensus expectations compiled from recent analyst coverage point to modest improvements in earnings per share over the coming year, although the projected EPS remains below the high watermark achieved in the strongest prior-year period. The gap between the consensus EPS estimate and the historical peak underscores how external forecasts still bake in an element of caution, even as analysts recognize the potential in Castellum’s contract pipeline and technology offerings.
For investors assessing Castellum stock at $0.62, the key question is whether the company can translate its guidance and contract opportunities into a sustained upward trajectory in revenue and earnings that justifies rerating the shares. A successful execution that lifts EPS toward or above the previous peak could narrow the valuation discount and support a higher share-price range, while continued margin pressure would likely keep the stock anchored around current micro-cap levels.
Business model and representative product
Castellum operates as a technology and services provider, focusing on secure and specialized solutions tailored to government and enterprise clients. Its business model combines software, integration services and long-term support contracts, creating a base of recurring revenue that can smooth out the impact of individual project wins or delays. The company positions itself as a partner that can help customers modernize critical systems while maintaining stringent security and compliance requirements.
A representative offering is its secure data and network integration platform, which is designed to connect disparate systems and applications while enforcing robust security policies and monitoring. Through this product, Castellum aims to address customer needs for interoperability and resilience, enabling organizations to share and analyze information safely across teams and locations. Performance metrics from recent deployments indicate that the platform can reduce integration timelines and improve system reliability, which in turn supports renewal rates and add-on sales.
Share price level and investor takeaway
Castellum stock trades at $0.62 as of the close of August 30, 2026, on its US listing, reflecting a micro-cap valuation and a narrow recent trading range. At this low absolute price level, the shares offer leveraged exposure to any future improvement in revenue growth and margins, but they also carry heightened volatility and execution risk for retail investors.
