Breaking Down Pulse Biosciences, Inc. (PLSE) Financial Health: Key Insights for Investors

You're looking at Pulse Biosciences, Inc. (PLSE) and trying to map the promise of their Nanosecond Pulsed Field Ablation (nsPFA) technology against the hard financial reality, and honestly, the numbers tell a classic biotech story: high burn for high potential. The company is defintely advancing, reporting a GAAP net loss of ($19.4) million in Q3 2025, a significant jump from the prior year, but this is the cost of pushing their technology through clinical trials for things like benign thyroid nodules and atrial fibrillation (AF). Still, the market is watching that cash runway, which stood at a comfortable $95.2 million as of September 30, 2025, even as Q3 operating activities burned around $13.04 million in cash. While total revenue for Q3 2025 was a modest $86 thousand from their limited market release, analysts are forecasting a full-year 2025 revenue of around $1.28 million, so the key question for you is whether the clinical milestones they are hitting-like enrolling subjects in the PRECISE-BTN study-will translate that cash cushion into massive commercial returns before the burn rate forces another capital raise.

Revenue Analysis

You're looking at Pulse Biosciences, Inc. (PLSE) right now, and the first thing to understand is that their revenue story isn't about massive growth yet; it's about a critical transition from pure research and development (R&D) to initial commercialization. They are just starting to move product, so the numbers are small, but the change is significant.

For the third quarter ended September 30, 2025, Pulse Biosciences reported total revenue of only $86 thousand. To be fair, this is a massive change from prior periods, as this figure marks the official commencement of their limited market release for their core technology. This is a classic biotech/med-device inflection point, where a tiny revenue number represents a giant leap in business model maturity.

Here's the quick math on their revenue streams:

• Primary Source: Sales of nPulse capital equipment and Vybrance disposables.
• Segment Contribution: Essentially 100% of revenue comes from the initial commercialization of their proprietary Nanosecond Pulsed Field Ablation (nsPFA) technology.
• Near-Term Growth: Revenue is expected to grow in the fourth quarter of 2025 as procedural adoption increases.

The $86 thousand in revenue for Q3 2025 is a product of their limited market release, specifically tied to procedures like the treatment of benign thyroid nodules with the nPulse Vybrance percutaneous electrode system. This means every dollar is a product sale, not a grant or a one-off license, which is defintely a stronger signal. What this estimate hides, though, is the massive cost of getting here-total GAAP costs and expenses for the quarter were $20.5 million.

The company is not yet generating revenue from its other promising applications, such as the nPulse Cardiac Surgery System for atrial fibrillation (AF) ablation, which is still in clinical study in Europe and the US. This means the current revenue, while small, is highly concentrated in the soft tissue ablation space. The real opportunity for substantial revenue growth lies in the successful commercialization of these other applications, which you can read more about in their Mission Statement, Vision, & Core Values of Pulse Biosciences, Inc. (PLSE).

To understand the current revenue profile, consider the breakdown of their sales mix:

The split between capital and disposables is the key to future margin expansion. Disposables represent the higher-margin, recurring revenue stream, and that's what we need to see accelerate in 2026. For now, the entire revenue base is a proof-of-concept for their commercial strategy.

Profitability Metrics

You're looking at Pulse Biosciences, Inc. (PLSE) and seeing a fascinating, but financially challenging, R&D-stage company. The direct takeaway here is that while the gross profit margin is deeply negative, which is a major red flag for a mature business, it's a clear signal of the company's current stage: heavy investment into a limited market release. This is a pre-commercialization profile, not a commercial failure.

For the third quarter of 2025 (Q3 2025), Pulse Biosciences, Inc.'s profitability ratios show a company still burning cash to validate its Nanosecond Pulsed Field Ablation (nsPFA) technology. Total revenue for the quarter was only $86 thousand, generated from the limited market release of its nPulse Vybrance percutaneous electrode system. This tiny revenue base is then overwhelmed by the cost of running a growth-focused medical device firm.

Here's the quick math on the core profitability ratios for Q3 2025, which are frankly shocking without context:

• Gross Profit Margin: -224.4%
• Operating Profit Margin: -23,737%
• Net Profit Margin: -22,558%

A Gross Profit of negative $193 thousand means the direct cost of making and selling their initial product is more than double the revenue generated. That's a defintely a cash-intensive launch. The GAAP net loss for the quarter was ($19.4) million, reflecting the significant investment in research and development (R&D) and selling, general, and administrative (SG&A) expenses.

Trends and Operational Efficiency

The trend in profitability is one of increasing losses, which is expected during a major clinical and commercial push. Total GAAP costs and expenses for Q3 2025 were $20.5 million, a substantial increase from $13.7 million in the prior-year period. This $6.8 million increase is mostly driven by administrative expenses to support the expanding organization, clinical trials, and commercialization efforts-a necessary evil for a company trying to scale a new technology platform.

Operational efficiency, as measured by margins, is currently terrible, but that's by design. Pulse Biosciences, Inc. is prioritizing market validation and clinical data over immediate cost management. The negative gross margin suggests they are intentionally pricing low or incurring high initial manufacturing/service costs to get their device, which you can read more about in their Mission Statement, Vision, & Core Values of Pulse Biosciences, Inc. (PLSE), into the hands of key opinion leaders and clinical sites.

Industry Comparison: A Reality Check

When you compare Pulse Biosciences, Inc.'s margins to the industry, you see the massive gap between a pre-commercial company and established peers. The average Gross Profit Margin for the broader Medical Devices industry is around 60.5%, with the Medical Instruments & Supplies segment averaging 54.5%.

What this estimate hides is the spectrum of the industry. The average Net Profit Margin for Medical Devices is also a negative -59.3%, showing that many smaller, innovative MedTech companies are also unprofitable. A more direct peer, a commercial-stage medical device company, reported a Q3 2025 Gross Margin of 74.3% and a Net Loss of ($8.0) million. This shows the potential high gross margin once Pulse Biosciences, Inc. achieves scale, but also that even commercial peers can run a net loss.

The table below maps Pulse Biosciences, Inc.'s reality against the industry averages:

The clear action for you is to stop focusing on current margins and instead track the rate of revenue growth in Q4 2025 and Q1 2026 against the rate of expense growth. If revenue starts growing faster than the net loss, the company is beginning its transition to a commercial-stage model.

Debt vs. Equity Structure

You need to know how Pulse Biosciences, Inc. (PLSE) is funding its operations, especially as a growth-stage medical device company. The direct takeaway is that the company operates with a remarkably conservative capital structure, choosing to fund its development almost entirely through equity, not debt. This means minimal interest risk, but significant shareholder dilution.

As of the most recent data (November 2025), Pulse Biosciences, Inc.'s leverage is extremely low. The company's long-term debt is reported as effectively zero in the latest periods, which is a rare and advantageous position for a company in the capital-intensive biotech space. This preference for non-debt financing means the company avoids the fixed obligations and refinancing risks that plague many of its peers.

The Debt-to-Equity (D/E) ratio for Pulse Biosciences, Inc. stands at approximately 0.09 as of late 2025. This is a critical figure. Here's the quick math: a D/E ratio of 0.09 means the company has only 9 cents of debt for every dollar of shareholder equity. This is a defintely low ratio, signaling a very strong balance sheet and high solvency. It's a clean balance sheet.

To put that 0.09 D/E ratio into context, consider the industry benchmarks. Pulse Biosciences, Inc. operates in the Surgical & Medical Instruments & Apparatus industry, where the median D/E ratio is closer to 0.70, and even the broader Biotechnology industry averages around 0.17. Pulse Biosciences, Inc. is significantly less leveraged than its industry peers.

• Debt-to-Equity Ratio: 0.09 (late 2025)
• Long-Term Debt: Effectively zero
• Industry Median D/E: 0.70 (Surgical & Medical Instruments)

The company's financing strategy clearly favors equity funding to support its research and development (R&D) and commercialization efforts for its Nanosecond Pulsed Field Ablation (nsPFA) technology. This is evident in its past financing activities, such as the 2024 Rights Offering, which generated net inflows of capital by issuing new equity securities. This strategy helps fund ongoing operating losses-which are common for a development-stage company-but it also introduces dilution risk for existing shareholders. The trade-off is clear: minimal debt risk for higher equity dilution.

What this estimate hides is the ongoing need for capital to advance clinical trials and commercialization. While the balance sheet is clean of debt, the reliance on equity means future fundraising rounds could further increase the number of shares outstanding.

Liquidity and Solvency

You're looking at Pulse Biosciences, Inc. (PLSE) and wondering if they have the cash to keep the lights on while they move their Nanosecond Pulsed Field Ablation (nsPFA) technology through clinical trials and into market. The direct takeaway is this: Pulse Biosciences, Inc. has a strong near-term liquidity position, but it is entirely dependent on external financing to cover its substantial operating burn rate.

Assessing Pulse Biosciences, Inc.'s Liquidity

The company's balance sheet as of the 2025 fiscal year shows exceptional short-term solvency. The two key metrics, the Current Ratio and Quick Ratio, are far above the industry average, which is a significant strength. The Current Ratio, which measures current assets against current liabilities, stands at approximately 10.02 for the fiscal year 2025. [cite: 9 (from first search)] This means they have over ten dollars in liquid assets for every dollar of short-term debt. The Quick Ratio, which excludes less-liquid assets like inventory, is nearly identical at 9.82, [cite: 9 (from first search)] confirming that the majority of their current assets are highly liquid cash and equivalents.

Here's the quick math on their working capital: As of September 30, 2025, Pulse Biosciences, Inc. reported total current assets of roughly $97.157 million. [cite: 3 (from first search), 5 (from first search)] Even using the Q2 2025 current liabilities of $8.978 million as a proxy, the net working capital is substantial, defintely ensuring they can meet immediate obligations.

• Current Ratio: 10.02 (FY 2025) [cite: 9 (from first search)]
• Quick Ratio: 9.82 (FY 2025) [cite: 9 (from first search)]
• Cash and Cash Equivalents: $95.2 million (Q3 2025) [cite: 3 (from first search)]

Cash Flow: The Burn Rate Reality

While the balance sheet looks pristine, the cash flow statement tells the story of a development-stage company. The working capital trends are positive in terms of sheer size, but they are being steadily eroded by a negative cash flow from operations. For the nine months ended September 30, 2025, Pulse Biosciences, Inc. used $39.4 million in cash for operating activities. [cite: 5 (from first search)] This cash burn is tied directly to their heavy investment in research and development (R&D) and expanding administrative expenses to support their clinical trials and eventual commercialization. Costs and expenses for Q3 2025 alone were $20.5 million. [cite: 4 (from first search)]

The cash flow breakdown for the nine months ended September 30, 2025, looks like this:

What this estimate hides is the source of the high cash balance. The company maintains its liquidity through financing activities-specifically, net inflows from equity and related financing activities, like warrant exercises. [cite: 2 (from first search), 3 (from first search)] They have virtually no long-term debt, [cite: 2 (from first search)] which is a strength, but it means their runway is finite and tied to their ability to raise more capital without relying on debt, which often results in share dilution.

Valuation Analysis

You're looking for a clear signal on whether Pulse Biosciences, Inc. (PLSE) is a buy, a hold, or a sell right now, and the short answer is that Wall Street's consensus is a Hold. This isn't a firm endorsement, but it reflects a high-growth, pre-profitability biotech company where traditional valuation metrics struggle to paint a full picture. The average analyst price target sits at $22.00.

The core of the issue is that Pulse Biosciences is still in its investment and commercialization phase, meaning it's not yet making money. This is typical for a company with a cutting-edge technology like its Nano-Pulse Stimulation (NPS) platform. You have to look past the negative numbers and focus on the growth trajectory and cash position.

Here's the quick math on the key valuation ratios based on the latest 2025 fiscal year data:

• Price-to-Earnings (P/E) Ratio: The trailing P/E ratio is currently negative, reported around -12.17. This simply confirms the company is unprofitable, which is expected given the forecast for Earnings Per Share (EPS) this year is -$1.19.
• Price-to-Book (P/B) Ratio: This ratio is high at approximately 10.52. A P/B over 1.0 suggests the stock is trading above its net asset value, but a P/B over 10.0 signals that investors are placing a significant premium on the company's intangible assets-specifically its proprietary technology and future growth potential-rather than its current balance sheet assets.
• Enterprise Value-to-EBITDA (EV/EBITDA): This metric is also not applicable (n/a) because the company has negative EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization). The Enterprise Value, which factors in market capitalization and debt minus cash, is around $888.53 million.

What this estimate hides is the high cash burn, but the company still holds a strong current ratio of 10.02 and cash and cash equivalents of $95.214 million as of September 30, 2025.

Stock Performance and Analyst Sentiment

The stock price trend over the last 12 months shows significant volatility, which is a defintely a risk you need to factor in. The stock price has ranged from a 52-week high of $25.00 to a recent 52-week low of $13.63. The last reported closing price was around $13.75 on November 18, 2025, reflecting a -17.19% decrease over the last 52 weeks. This recent dip, which hit a new 52-week low, suggests market skepticism or profit-taking despite the long-term growth story.

Pulse Biosciences, Inc. does not pay a dividend, with a dividend yield of 0.00% and a payout ratio of 0.00%. This is standard for a growth company that is reinvesting every dollar back into research, development, and market expansion for its CellFX nsPFA technology (Nano-Pulse Stimulation).

The analyst consensus is a Hold, with one analyst rating a 'Buy' and another a 'Sell'. The average price target of $22.00 implies a potential upside of over 60% from the recent stock price, but this hinges entirely on the successful commercialization of their medical devices. You are betting on execution and regulatory success here, not current cash flow.

Risk Factors

You're looking at Pulse Biosciences, Inc. (PLSE) as a high-growth, high-risk play, and you're right to focus on the downside. The biggest immediate risk isn't competition; it's the sheer cash burn rate relative to initial revenue. The company is in a critical transition from pure R&D to commercialization, and that costs serious money.

For the third quarter of 2025, the company's financial health showed a stark reality: a GAAP net loss of ($19.4) million on total revenue of only $86 thousand. That's a massive disconnect. Here's the quick math: Cash used in operating activities was $13.0 million for the quarter, up from $9.0 million in the prior year period, showing the cost of scaling up. This cash bleed is the core financial risk.

As of September 30, 2025, Pulse Biosciences had $95.2 million in cash and cash equivalents. With the current burn rate accelerating, that cash runway is shrinking faster than the prior annual burn rate of around $40 million might suggest. The company needs to rapidly convert its Nanosecond Pulsed Field Ablation (nsPFA) technology's clinical progress into meaningful revenue, or it will need to raise more capital, which means shareholder dilution.

The operational and strategic risks are all tied to their core technology platform. This is a medical device company, so regulatory and clinical success are defintely the lifeblood. The entire valuation hinges on the successful completion of pivotal clinical studies and subsequent FDA approvals.

The company is mitigating this risk by focusing on key clinical milestones, which is the right move. They are advancing studies like PRECISE-BTN for benign thyroid nodules and the NANOCLAMP AF study for atrial fibrillation (AF) surgical ablation, which received FDA Investigational Device Exemption (IDE) approval. Still, any setback-a trial delay, unexpected clinical data, or a prolonged FDA review-could immediately crater the stock price.

The external risks center on market adoption and competition. While nsPFA is a novel mechanism, Pulse Biosciences will face established players in the cardiac and soft tissue ablation markets. These incumbents have massive sales forces, deep pockets, and existing relationships with hospitals and physicians. They will not sit still as a new technology tries to disrupt their space. The challenge is not just getting regulatory clearance, but securing reimbursement and driving physician adoption against entrenched alternatives.

The core actions for investors are clear: watch that cash burn and track clinical progress. If you want to dive deeper into the full financial picture, you can read more at Breaking Down Pulse Biosciences, Inc. (PLSE) Financial Health: Key Insights for Investors.

Growth Opportunities

You're looking at Pulse Biosciences, Inc. (PLSE) because its technology is defintely disruptive, but the financials still look like a high-burn startup. The direct takeaway is this: the company's near-term growth pivots entirely on the commercial success of its proprietary Nanosecond Pulsed Field Ablation (nsPFA) technology in soft tissue ablation, specifically benign thyroid nodules, and the regulatory progress of its cardiac devices.

Pulse Biosciences's strategy for 2025 is laser-focused on moving its CellFX nsPFA platform from clinical validation to early commercial revenue. They've already generated initial revenue, reporting $86,000 in the third quarter of 2025 from a limited market release, which is a small but critical start. The real opportunity lies in the fact that analysts project the company's annual revenue will grow at a rate of 220.5% per year, which is a massive acceleration.

Here's the quick math on the near-term financial picture, based on the latest consensus estimates for the 2025 fiscal year. The company is in a heavy investment phase, so expect losses, but the revenue jump into 2026 is the key metric to watch.

What this estimate hides is the execution risk in a medical device launch. Still, the company is sitting on a decent cash cushion of $119.3 million as of Q1 2025, which gives them runway to execute their pivotal clinical trials and commercialization plans.

Product Innovation and Strategic Initiatives

The core growth driver is the CellFX nsPFA platform, which uses nanosecond pulses of electrical energy to clear cells non-thermally, sparing adjacent noncellular tissue. This is a game-changer because it allows for deeper ablation with lower energy, reducing the risk of thermal damage compared to older technologies. This unique mechanism is their competitive advantage.

Their strategic initiatives for 2025 are clear action items for investors to track:

• Soft Tissue Ablation Commercialization: Driving early adoption of the nsPFA Percutaneous Electrode System for treating benign thyroid nodules. They've already treated over 140 patients in their pilot program and initiated the Precise BTN clinical study with up to 50 patients.
• Cardiac Market Entry: Initiating IDE pivotal studies for both the nsPFA Cardiac 360° catheter and the cardiac surgical clamp for Atrial Fibrillation (AF) treatment. The surgical clamp even has an FDA breakthrough device designation, which helps expedite the regulatory process.
• Clinical Validation: Leveraging their seven FDA clearances and initial clinical data, including treating 100 patients in Europe with the nsPFA 360° catheter, to de-risk the technology for the US market.

The entire strategy is built on the belief that nsPFA will become the next-generation leader in pulse field ablation. To understand the long-term vision behind these moves, you should review their Mission Statement, Vision, & Core Values of Pulse Biosciences, Inc. (PLSE).

The biggest opportunity is in the cardiac space, where the surgical clamp and catheter could transform AF treatment. But, honestly, the near-term revenue is coming from the thyroid nodule market, so watch those commercial adoption metrics closely.

Next Step: Track the enrollment progress and initial data readouts from the Precise BTN study and the commencement of the cardiac IDE pivotal trials, as these are the immediate triggers for stock movement.
