Zscaler Q4 Earnings Report: A Mixed Bag for Investors Amid Broader IT Services Sector Optimism

Introduction: A Volatile Earnings Season for Zscaler in a Stronger Sector

As Q4 2025 came to a close, Zscaler (ZS) released its latest earnings report on September 2, 2025, against a backdrop of cautious optimism in the IT Services sector. With a strong macroeconomic recovery showing signs of tailing off, investors were keenly watching for clues on whether Zscaler could maintain its growth trajectory amid rising costs and competitive pressures. The company’s performance, while showing solid top-line growth, also revealed ongoing profitability challenges that have persisted in previous quarters.

Zscaler’s results were contrasted with the broader industry trend, where peers in the IT Services sector have generally shown more sustained positive returns following strong earnings. This set the stage for an earnings analysis that delves into both the company’s financials and the historical market reaction to its performance.

Earnings Overview & Context

For the fourth quarter of 2025, Zscaler reported $1.575 billion in total revenue, up from previous periods and in line with the expectations of a recovering IT demand. However, the company posted a net loss of $42.8 million, or $0.29 per share, driven primarily by elevated operating expenses. Operating income came in at $-22.2 million, with total operating expenses hitting $1.25 billion.

Breaking this down further:- Marketing, selling, and general administrative expenses totaled $961.8 million, signaling continued investment in go-to-market initiatives.- Research and development (R&D) expenses remained high at $360.7 million, reflecting ongoing innovation efforts.- Interest income exceeded expenses, with net interest income of $72.4 million due to favorable returns on cash reserves.

Despite the revenue beat, the earnings shortfall reflects a common trend for high-growth technology firms investing heavily in operations and R&D to drive long-term value.

Backtest Analyses

Stock Backtest: Zscaler’s Earnings-Driven Price Reactions

The historical performance of Zscaler around earnings announcements reveals a pattern of initial optimism followed by some volatility. According to the backtest results, ZS has a 66.67% win rate within three days of an earnings beat, with an average return of 0.83%. This suggests that the market often reacts positively to strong reports, rewarding investors in the short term.

However, this optimism does not always hold. Over the next 10 days, the win rate drops to 58.33%, with an average return of -0.25%, indicating some correction or profit-taking after the initial rally. It is only after 30 days that the win rate stabilizes again at 58.33%, with an average return of 2.20%. The maximum observed return of 4.46% occurs 55 days post-event.

These findings suggest that investors may benefit from a short-term hold after an earnings beat, while longer-term performance requires continued validation of Zscaler’s strategic direction and execution.

Industry Backtest: Sector-Level Performance Post-Earnings

When placed in the context of the broader IT Services sector, Zscaler’s results are in line with the industry trend, though with a different pace. On average, IT Services stocks experience a positive return of up to 2.22% around 51 days post-earnings beat. This delayed but consistent market reaction suggests that the industry rewards earnings surprises more gradually than immediately.

This longer-term response implies that investors may need to adopt a more patient approach with IT Services stocks, particularly if they are betting on the cumulative effect of strong earnings performance across the sector.

Driver Analysis & Implications

Zscaler’s Q4 earnings reflect a company still in a growth phase, with a clear focus on expanding R&D and sales capabilities to maintain its leadership in cloud security. Despite the net loss, the company is reinvesting aggressively in infrastructure and innovation, which may pay dividends in the long term.

However, the rising operating expenses—particularly in marketing and general administration—indicate that Zscaler is still in a high-cost growth stage. These internal drivers are aligned with the broader macroeconomic trend of firms investing heavily in digital transformation, which supports the IT Services sector’s long-term outlook.

Investment Strategies & Recommendations

Given the mixed short-term and long-term signals, investors may want to consider a balanced approach. For the short term, a “hold” strategy is recommended, especially for those who captured gains in the initial positive price reaction. A close watch on Zscaler’s guidance and subsequent performance will be crucial for timing any further entry points.

For long-term investors, the key is to monitor for signs of sustained growth and improving operating leverage. The company’s high R&D spending could pay off if it continues to innovate and capture market share. In this context, investors may consider dollar-cost averaging into ZS shares, particularly if broader IT Services trends remain supportive.

Conclusion & Outlook

Zscaler’s Q4 earnings offer a glimpse of growth potential amid ongoing financial challenges. While the company’s top-line performance is encouraging, its path to profitability remains uncertain. The broader IT Services sector, however, continues to show resilience post-earnings, suggesting a cautiously optimistic outlook.

The next key catalyst for Zscaler will be its earnings guidance for Q1 2026, which will give investors a clearer view of the company’s ability to scale profitably. Until then, investors should stay nimble and closely monitor both ZS’s financial trajectory and broader sector dynamics.
