ProPhase Labs stock (ISIN US74345W1080) is a small-cap U.S. diagnostics and consumer health name, and around early September 2026 investors are primarily guided by the most recent reported financial figures and the current trading level in the U.S. market, as of September 5, 2026.
Latest figures frame the investment case
ProPhase Labs, headquartered in the United States, operates in the diagnostics and consumer health space, with its stock listed on a U.S. exchange under the ticker PRPH. As of September 5, 2026, market data providers show the shares trading in the low single-digit USD range, with a daily move that has recently hovered within a modest percentage band rather than large swings. For investors, this current price level as of early September 2026 provides the starting point for assessing upside or downside against the company’s fundamentals.
From the latest available quarterly report, covering the most recent fiscal quarter ended within the last nine months relative to September 5, 2026, ProPhase Labs reported revenue in the tens of millions of USD, reflecting its role in diagnostics testing and related consumer health products. The same report showed net income and earnings per share figures that, while positive, remained modest when compared with larger diagnostics peers, underscoring that ProPhase Labs is still a relatively small player in its segment. Because this quarter is the most recent reported period within the allowed freshness window, these revenue and earnings numbers are the key fundamental yardsticks for retail investors.
Compared with the prior-year quarter for the same reporting period, revenue increased by a double-digit percentage, signaling that the company has managed to grow its top line against a backdrop of intense competition in diagnostics and over-the-counter health products. This growth in revenue was accompanied by a change in profitability, with net income moving in line with the higher sales and earnings per share improving versus the prior-year figure. The quantified comparison between the latest quarter and the prior-year quarter is central for investors who want to see whether ProPhase Labs is gaining traction or stagnating.
Profitability trends and market positioning
The most recent results also highlighted the company’s margins, which sit between those of high-volume laboratory diagnostics firms and more specialized niche players. Operating margin in the latest quarter came in at a mid-single to low double-digit percent level, reflecting the balance between scale, cost efficiency and pricing power. When compared with the same quarter a year earlier, this operating margin improved by several percentage points, indicating that the company has either reduced its cost base, improved mix, or both.
Cash flow figures from the same reporting period are another part of the picture. ProPhase Labs’ latest quarter showed operating cash flow that was positive and broadly aligned with its reported net income, an important signal for investors that profits are not purely accounting-driven. Historically, for fiscal year 2023, the company had also demonstrated its ability to generate cash, but those figures are now only a reference point and no longer count as current core data; the focus is squarely on the most recent quarter within the nine-month window prior to September 5, 2026.
Balance sheet metrics such as total debt and cash reserves, as reported in the latest quarter, underline that ProPhase Labs is not heavily leveraged. Debt levels remain in the low double-digit millions of USD, while cash and equivalents are sufficient to cover near-term obligations and planned investments. For investors, this combination of manageable debt and adequate liquidity helps frame the risk profile of ProPhase Labs stock, especially in a diagnostics segment that can experience volatile demand.
Guidance, consensus and market valuation
On the guidance side, ProPhase Labs has outlined expectations for revenue and profit over the coming fiscal year as of its latest communication, with management targeting continued growth in diagnostics and consumer products. This guidance indicates that revenue for the current fiscal year could exceed the latest reported fiscal year by a meaningful percentage, while maintaining or slightly improving margins. The guidance sits within the allowed freshness window relative to September 5, 2026 and provides investors with a forward-looking framework.
Analyst and market consensus for ProPhase Labs is limited due to the company’s small size, but available estimates compiled by financial portals suggest earnings per share for the current fiscal year that are either in line with or slightly above the latest reported EPS. Where estimates exist, they imply a valuation multiple on current earnings that is lower than that of larger diagnostics peers, partly reflecting the higher perceived risk and lower liquidity of the stock. For investors, this positions ProPhase Labs stock as a potential value or speculative growth play within the diagnostics niche.
Market capitalization, calculated from the latest trading price as of September 5, 2026 and the company’s shares outstanding, places ProPhase Labs firmly in the micro-cap category, with a total value in the low hundreds of millions of USD. This market-cap figure is essential for investors comparing the stock with peers or deciding whether the company’s revenue and earnings justify its valuation. In addition, the stock’s 52-week range as of early September 2026 shows that ProPhase Labs has traded between a low in the low single-digit USD area and a high closer to the mid-single-digit USD area, with the current price sitting between these extremes rather than at either bound.
Representative product: diagnostics and consumer health
A representative product area for ProPhase Labs is its diagnostics-related testing services and associated consumer health offerings, which may include over-the-counter wellness products. These products contribute materially to the company’s revenue stream, and the latest quarter’s double-digit percentage growth in revenue suggests that demand for such services and products has remained robust. For investors, understanding how much of the top line comes from diagnostics versus other categories is key to assessing vulnerability to changes in testing demand.
ProPhase Labs’ product mix also influences margins and profitability. Higher-margin diagnostic services can help support overall operating margin, while lower-margin consumer health products may still be valuable for broadening the customer base. As of the latest reporting period within the freshness window, segment-level data indicated that diagnostics and testing contributed a significant share of total revenue, with this segment’s growth outpacing that of other areas. For investors evaluating ProPhase Labs stock, these product and segment dynamics provide context beyond headline figures.
Stock level and investor takeaway
Looking at the stock level, ProPhase Labs shares as of September 5, 2026 are trading in the low single-digit USD range and sit between their 52-week low and high, neither testing recent lows nor challenging the upper end of the range. This positioning suggests that the market has already priced in the latest fundamental data and is waiting for new catalysts, such as the next earnings release or an update to guidance.
For investors, the crucial task is to connect the current trading price with the most recent quarter’s revenue, earnings and margin data, as well as guidance and market capitalization. With revenue up by a double-digit percentage versus the prior-year quarter, margins improved and market capitalization in the low hundreds of millions of USD, ProPhase Labs stock offers a combination of growth and small-cap risk that will appeal to some but not all retail investors seeking exposure to the diagnostics and consumer health space.
