The PEG (Price/Earnings to Growth) ratio is a key tool for evaluating growth stocks, introduced by Peter Lynch.

PEG < 1: Undervalued – A ratio below 1 suggests the stock is undervalued. For example, if the P/E is 15 and earnings are expected to grow by 20%, the PEG would be 0.75, indicating a good buying opportunity.

PEG = 1: Fair Value – A PEG of 1 means the stock price matches its growth expectations, representing fair value.

PEG > 1: Overvalued – A PEG above 1 indicates the stock may be overvalued, as its price is higher than its projected growth rate, making it riskier.

Valuation comparison

Analysts’ revenue growth forecast for $PANW in 2025 is +16.3%, and +13.4% for 2026. Considering this forecast, the valuation based on the EV/Sales multiple appears fair when compared to other companies in the cybersecurity sector.

We’ll evaluate the company’s economic moat, which supports long-term revenue growth, analyze revenue trends and the forecast for next quarter, and identify key factors that could help the company exceed expectations and sustain future growth.

We’ll assess the performance of key segments, the launch of new products and updates, customer acquisition growth, key financial metrics, financial stability, and margin trends.

Additionally, we’ll review the SBC/Revenue ratio, shareholder dilution, and finally, draw conclusions on the company’s outlook.

3. Economic Moat

Economic Moats enable companies to remain stable during crises and support long-term revenue growth.

Economies of Scale

Palo Alto Networks exhibits powerful economies of scale that have strengthened with growth. The company maintains a non-GAAP gross margin above 75% in Q2, showcasing operational efficiency across an expanding revenue base. With over 85,000 organizations in 150+ countries using its platform, Palo Alto Networks benefits from cost advantages in R&D, manufacturing, and operations. Scale enables heavy investment in innovation—around 15% of revenue—while sustaining profitability. Holding a 22.9% market share in network security deepens supplier relationships and procurement leverage, reinforcing a durable scale moat.

Network Effect

The company’s network effect in threat detection is significant. Its AI systems process 1.5 trillion network events daily with 99.7% detection accuracy. Each additional customer strengthens the system’s intelligence, improving protection speed and precision. With insights from 85,000 global clients, Palo Alto Networks identifies and stops threats up to 180x faster than competitors. Its XSIAM platform ingests 12 petabytes of data per day, enabling real-time analytics and rapid incident response. As adoption grows, the network becomes smarter and increasingly difficult to replicate.

Brand Strength

Palo Alto Networks commands one of the most trusted brands in cybersecurity. Recognized as a Leader in Gartner’s Magic Quadrant for Network Firewalls, the company serves 85 of the Fortune 100 and over 50% of U.S. federal agencies. Operating in 150+ countries, it now leads in 13 analyst-recognized categories, up from 9 in 2020. With a Net Promoter Score of 67 and 98% “Willingness to Recommend” on Gartner Peer Insights (based on 198 reviews, January 2025), the brand drives shorter sales cycles and higher conversion rates—creating a reputation moat few can match.

Intellectual Property

Palo Alto Networks holds over 1,200 active patents and files roughly 300 new applications annually. As of April 2025, it manages 2,013 active patents and applications, reflecting consistent innovation across network, cloud, and AI-driven security. While the company faced a $151.5 million settlement with Centripetal Networks, its expanding IP base forms a strong defensive barrier. Sustained patent growth supports leadership in proprietary cybersecurity technologies and AI systems.

Switching Costs

Leaving Palo Alto Networks carries high operational risk. Average downtime costs $5,600 per minute, deterring platform transitions. Its integrated architecture—spanning network, cloud, and security operations—makes replacement expensive and complex. According to Forrester, customers report a 50% reduction in security management effort using the unified platform. The company amplifies lock-in through deep integration between SIEM and endpoint solutions, such as XSIAM’s required Cortex agent usage. By offering free products for the duration of competitors’ contracts, Palo Alto accelerates platform adoption, knowing high switching costs ensure enduring customer loyalty.

Palo Alto Networks’ wide economic moat is built on multiple reinforcing competitive advantages, with switching costs and network effects providing the strongest protection. The combination of these moats creates a formidable defensive position that should enable sustained profitability and market leadership in the growing cybersecurity market.

4. Revenue growth

$PANW — revenue growth in Q2 accelerated to +15.8% YoY, continuing the recovery from Q2 2024, when growth had slowed to +12.1% YoY.
If the company beats next quarter’s guidance by ~1.0%, as it did in Q2, Q3 growth could reach +16.7%, signaling continued revenue acceleration.

RPO growth in Q2 accelerated to +24.2% YoY, well ahead of revenue, indicating strong forward demand.
On the flip side, billings grew +6.5% YoY, which is slower than both last quarter and overall revenue growth.

5. Segments and Main Products.

8. KPI

ARR Growth

Palo Alto $PANW NGS ARR growth is slowing, reaching +32% YoY in Q2, which is above the company’s revenue growth.

Net new ARR

Palo Alto $PANW added $490 million in net new NGS ARR in Q2 2025, reflecting +11% YoY growth. This was the highest net new NGS ARR in the company’s history

CAC Payback Period and RDI Score

$PANW’s return on S&M spending is 5.5. The CAC Payback Period has improved compared to the previous quarter and remains better than the average for SaaS companies (the median among those I track is 21.5 months).

The R&D Index (RDI Score) has significantly declined over the past two years and currently stands at 1.01 for Q2, which is below the median of 1.2 for the SaaS companies I monitor but above the industry median of 0.7.

An RDI Score above 1.4 is considered indicative of best-in-class performance. The low industry median of 0.7 highlights the importance of efficient R&D investment.

Profitability

Over the past year, $PANW Palo Alto margins has changed:

• Gross Margin slightly decreased from 76.8% to 75.8%.

• Operating Margin increased from 26.9% to 30.3%.

• Free Cash Flow (FCF) Margin increased from 21.2% to 36.8%.

Operating expenses

$PANW’s non-GAAP operating expenses have slightly decreased, primarily due to reduced Sales & Marketing (S&M) spending, which declined from 29% two years ago to 28%.
R&D expenses remain high at 14%, as the company continues to invest in future growth through product enhancements and updates.
General & Administrative (G&A) expenses have slightly decreased and are now at a relatively low level of 3%.

Balance Sheet

$PANW Balance Sheet: Total debt stands at $417M, while Palo Alto holds $2,903M in cash and cash equivalents, exceeding total debt and ensuring a healthy balance sheet.

Dilution

$PANW Shareholder Dilution: Palo Alto’s stock-based compensation (SBC) expenses have slightly increased over the past two quarters, reaching 15% of revenue in the last quarter, which is relatively low for SaaS companies.
Shareholder dilution remains elevated—despite a slight decline, the weighted-average number of basic common shares outstanding is still relatively high, having increased by 3.2% YoY.

9. Conclusion

$PANW is leaning into platformization — offering select products for free short-term to drive long-term customer lock-in. The strategy seems to be working: revenue growth has re-accelerated over the past year, reaching +15.8% YoY in Q2. It’s likely that the slowest point of revenue growth (+12.1% YoY in Q2 FY2024) is now behind us, as Palo Alto’s platformization strategy begins to show real traction.

The cybersecurity TAM is massive at around $110B, growing at roughly +14% CAGR. With only about 4% market share captured via $5.1B in ARR, Palo Alto Networks still has plenty of room to grow.

Palo Alto also maintains a wide economic moat, built on multiple reinforcing competitive advantages that form strong barriers to entry in the cybersecurity market — this remains the company’s most powerful defense in an increasingly competitive space.

Leading Indicators:

• RPO growth of +24.2% outpaced revenue growth
• Billings grew +6.5%, lower than revenue growth
• Net new ARR additions at record level +11 YoY, while NGS ARR grew +32.2% YoY, outpacing total revenue growth

Key Indicators
• CAC Payback Period improved to 5.5 months, which is much better than average
• RDI Score increased slightly to 1.01, but remains below the median of other SaaS companies I track

Management explained that billings growth lagging revenue growth reflects a shift in customer buying behavior toward annual payment structures and larger platformization deals with deferred payments. This temporarily dampened near-term billings growth, even as total RPO and ARR continued to expand.

Management also issued a strong forecast for the next quarter, pointing to a likely acceleration in revenue growth, supported by leading indicators — such as RPO and NGS ARR growth outpacing revenue, along with record net new ARR additions.

Improvements in both the CAC Payback Period and RDI Score indicate meaningful progress in operational efficiency. Customers generating $5M and $10M in ARR grew roughly 50% YoY, while $20M+ ARR customers increased by ~80% YoY. Platform customer net retention remained strong at around 120%, showing durable customer engagement and expansion.

The company trades at a Forward EV/Sales multiple above its historical average and near all-time highs. The PEG ratio is also elevated, but valuation appears reasonable relative to peers, given Palo Alto’s long-term growth outlook.

One concern is that gross margin has continued to decline over the past two years, though operating margin and FCF margin have both improved YoY, which is positive.

I’m currently on the sidelines with $PANW, but closely tracking the company’s performance. I believe cybersecurity remains one of the most attractive sectors for long-term investing.
