Zscaler's AI security surge offset by slowing growth guidance and rising competition

  • AI security demand drives record deals Zscaler's Q4 fiscal 2026 results beat estimates with $1.19 EPS and $898M revenue, sending shares up 11% after hours. AI security demand drove record million-dollar deals, with over half the Fortune 500 now customers.

    This point highlights the positive impact of AI security demand on Zscaler's financial performance and stock price.

  • Fiscal 2027 guidance implies growth slowdown Fiscal 2027 guidance implies growth slowing to ~17% from 25%, triggering a 7.8% stock drop and a 3% workforce cut. This signals potential challenges ahead and weighed on investor sentiment.

    This point explains the negative reaction to the company's forward-looking guidance, which is a key driver of the stock's performance.

  • Palo Alto Networks intensifies competition Palo Alto Networks posted 40% SASE bookings growth and $400M in displacements, threatening Zscaler's core secure networking business and potentially pressuring market share and pricing.

    This point underscores the competitive pressures that could limit Zscaler's growth and negatively affect its stock price.

Zscaler's AI security push grows, but slower 2027 growth and competition weigh

  • Slower 2027 growth and AI restructuring Zscaler's fiscal 2027 guidance points to about 17% growth, down from 25%, and the company is cutting roughly 3% of staff to focus on AI. Investors worry demand is cooling, which pushed the stock down 7.8% on the news.

    This is the main new negative force behind the stock's recent drop and explains why growth concerns persist.

  • New AI security products and strong bookings Zscaler launched Agentic SOC, a new AI-powered security tool, and reported AI-security bookings above $100 million, up 50% from the prior quarter. Record $1 million deals and more Zero Trust customers show its AI bet is gaining traction, supporting future revenue.

    This shows the company's growth engine is expanding, which could offset slower overall growth and lift the stock.

  • Sector-wide AI safety bid lifts cybersecurity stocks Warnings from AI leaders about safety risks sparked a broad rally in cybersecurity stocks, with Zscaler jumping 12% in one day. This shows that rising AI fears can drive demand for security solutions, benefiting Zscaler even if the move is partly sentiment-driven.

    It highlights a new demand catalyst from AI safety concerns that directly boosted Zscaler's shares.

  • Intensifying competition in SASE Palo Alto Networks reported 40% SASE bookings growth and $400 million in displacements, aiming to become market leader. This signals tougher competition for Zscaler's core secure networking business, which could pressure its market share and pricing.

    It is a new competitive threat that could limit Zscaler's growth and weigh on the stock.

Zscaler beats Q4, AI demand strong, but 2027 growth slows

  • Q4 earnings beat and strong guidance Zscaler reported Q4 EPS of $1.19 and revenue of $898 million, beating estimates, and issued fiscal 2027 revenue guidance above consensus. Shares jumped 11% after hours. This directly boosts the stock because it shows the company is growing faster than expected and management sees continued demand.

    This is the main new event that moved the stock and answers why it's moving now.

  • AI security demand drives record deals CEO Jay Chaudhry said AI is a big tailwind, driving demand for AI security and zero trust. Zscaler had record million-dollar-plus deals and now serves over 50% of Fortune 500 companies. This supports future revenue growth and makes the stock more attractive.

    It explains the underlying demand trend that is pushing the stock up.

  • 2027 growth expected to slow Zscaler's fiscal 2027 revenue guidance implies growth of about 17%, down from 25% in fiscal 2026. This slowdown could pressure the stock because investors may worry that the rapid growth is fading, even though the company still expects double-digit growth.

    It is a key counterweight that could limit the stock's upside and is part of the new guidance.

  • High short interest could fuel further gains Jim Cramer noted that 5.9% of Zscaler's float is short, higher than peers. After strong results, short sellers may be forced to buy back shares, pushing the price higher. This adds a potential catalyst for the stock.

    It highlights a technical factor that could amplify the stock's move after earnings.

Q2 2026

Zscaler's strong demand and cyber warnings offset fraud probe and competition

  • Z-Flex drives strong demand Zscaler's Z-Flex program generated over $480 million in total contract value in the third quarter, up more than 60% sequentially. This flexible purchasing model encourages customers to commit to multi-year deals and adopt more products, pushing annual recurring revenue up 25% to $3.5 billion. This strong demand supports the stock price.

    This shows a key growth driver that directly boosts Zscaler's revenue and investor confidence.

  • Cyber threat warnings lift security stocks A joint warning from U.S. and international agencies about Russian cyber threats against critical infrastructure increased demand for cybersecurity services. Zscaler shares jumped as investors bet on higher spending. The stock has returned 9.5% over the past month, though it remains down 35.7% year to date.

    This event directly caused a sharp share price move and highlights how geopolitical tensions drive demand for Zscaler's services.

  • Securities fraud investigation weighs on stock Pomerantz LLP is investigating Zscaler for possible securities fraud related to its May 26 guidance miss. The stock had already fallen 31.5% on that miss. The investigation adds legal uncertainty and could lead to fines or reputational damage, pressuring the stock price.

    This is a new negative development that could affect investor confidence and lead to financial penalties.

  • Palo Alto Networks' SASE growth intensifies competition Palo Alto Networks reported its SASE annual recurring revenue hit $1.6 billion, up 40% year over year, more than twice the market growth rate. It also recorded nearly 50 displacement wins worth $200 million. This shows strong competition taking market share, which could limit Zscaler's growth and pressure its stock.

    This highlights a major competitive threat that could slow Zscaler's revenue growth and market share gains.

Core Scientific's AI pivot drove gains, but sector risks weighed

  • AMD AI Deal and Analyst Upgrades Core Scientific signed a 15-year, $14 billion deal with AMD to provide up to 2.5 GW for AI data centers, prompting analyst upgrades and a Third Point stake.

    This major deal and resulting analyst optimism were key positive drivers for the stock.

  • Oklahoma Expansion The company bought a 440 MW site in Oklahoma for $444 million, expanding its Muskogee campus toward 1.5 GW to support AI infrastructure growth.

    This expansion supports future capacity and growth prospects, positively impacting the stock.

  • Sector Selloff on Hardware Writedown IREN's $638.8 million hardware writedown triggered a sector selloff, dragging CORZ down 7% and highlighting risks of capital-intensive hardware obsolescence.

    This event directly caused a decline in CORZ's stock price during the period.

  • Payoff Uncertainty and Financing Risks Miners spent $30.7 billion on AI infrastructure versus just $341 million in AI revenue, creating payoff uncertainty; undisclosed financing terms on the Oklahoma purchase add cash risk.

    These factors create uncertainty and potential financial strain, negatively impacting investor sentiment.

CORZ Expands Power and AMD AI Lease as Costs and Peer Risk Grow

  • CORZ buys 440 MW Oklahoma power site for $444M Core Scientific closed a $444 million cash purchase of Polaris DS, adding about 440 megawatts of grid-connected power in Oklahoma and pushing its Muskogee campus toward 1.5 gigawatts. More leasable power means more future AI rental income, which supports the stock. But financing terms were not disclosed, so the cash cost is a real risk.

    This is the period's biggest company-specific event and directly expands CORZ's AI hosting capacity.

  • AMD's AI roadmap confirms 2.5 GW Core Scientific commitment AMD's data center revenue more than doubled and its Helios platform has secured commitments for up to 2 gigawatts of MI450 GPUs and 2.5 gigawatts of data center capacity from Core Scientific. A strong, committed AI chip partner makes CORZ's future lease revenue more credible and draws investor attention.

    It shows the AMD partnership is backed by real product demand, not just a headline deal.

  • IREN writedown triggers sector-wide AI data center selloff IREN's $638.8 million impairment on obsolete mining hardware sent its shares down 13% and dragged CORZ and other AI data center pure plays down 7% each. The episode shows investors punish capital-intensive operators when old equipment loses value, a reminder that CORZ carries similar hardware and spending risk.

    It is the period's clearest negative price driver and highlights a risk that applies directly to CORZ.

  • Dan Loeb's Third Point opens a Core Scientific stake Billionaire investor Dan Loeb's hedge fund disclosed a new $1.38 million position in Core Scientific, alongside bigger bets on other Bitcoin miners pivoting to AI. A well-known fund buying in signals confidence in the AI landlord strategy and can attract other investors to the stock.

    It is new evidence of institutional money backing the AI pivot that drives CORZ's story.

Core Scientific pivots to AI data centers with AMD deal, but spending risks loom

  • AMD deal transforms Core Scientific into AI data-center landlord Core Scientific signed a 15-year, $14 billion deal with AMD to provide up to 2.5 gigawatts of data-center capacity, starting with over 500 megawatts in 2027. This shifts its business from Bitcoin mining to hosting AI computing power.

    This is the central new event that redefines Core Scientific's business and drives bullish sentiment.

  • Analyst upgrades and price target hikes on AI pivot KBW upgraded Core Scientific to Outperform with a $28 target, and BTIG raised its target to $38. Morgan Stanley's projected 38 GW power shortage makes Core Scientific's ready-to-use sites scarce and valuable.

    Analyst actions and power shortage projections directly boost investor confidence and the stock's perceived value.

  • AI rally and miner ETF surge spotlight the shift AMD's AI rally and a 97% surge in a miners ETF highlighted the industry's move to AI, with potential contracted revenue for Core Scientific cited as high as $24 billion.

    Market momentum and sector enthusiasm amplify the positive narrative around Core Scientific's transformation.

  • Heavy AI spending with little revenue raises payoff uncertainty Miners spent $30.7 billion on AI data centers in 2026 versus just $341 million in AI revenue—roughly 15 times spending. This heavy upfront cost and uncertain payoff could pressure the stock if returns disappoint.

    This is the main risk that could undermine the bullish thesis and drag on the stock price.

AMD Deal and AI Landlord Shift Drive CORZ, but Heavy Spending Is a Risk

  • AMD deal nearly doubles leased capacity and adds $24B potential revenue Core Scientific's new AMD partnership gives AMD access to over 500 megawatts of data-center space from 2027, expandable to 2.5 gigawatts. This almost doubles total leased power to about 1.1 gigawatts and could bring in more than $24 billion over many years, making future rental income larger and more predictable.

    This is the biggest new event of the period and directly explains why CORZ is moving.

  • AI power shortage makes existing Bitcoin-mining sites more valuable Morgan Stanley projects a 38-gigawatt electricity gap for U.S. data centers through 2028. Repurposed Bitcoin mining sites like Core Scientific's are named as a solution. This boosts CORZ because its ready-to-use power and land become scarce, valuable assets that AI customers need.

    It explains a broad industry force that lifts demand for CORZ's power assets.

  • AMD's AI push and miner ETF surge spotlight CORZ's landlord role AMD reported strong sales and launched new AI products, reinforcing its partnership with Core Scientific. Meanwhile, a Bitcoin miners ETF jumped 97% in a year even as bitcoin fell 46%, because investors now value these companies for AI leases. This draws more attention and money to CORZ.

    It shows growing investor recognition of CORZ's AI landlord business, supporting the stock.

  • AI spending is 15 times AI revenue, raising concerns about heavy costs Listed Bitcoin miners spent $30.7 billion on AI data centers in 2026, but reported only $341 million in AI revenue in the first half — about 15 times spending. Core Scientific accounts for most of the revenue increase, but the huge gap means big upfront costs and uncertain payoffs, which could pressure the stock if returns disappoint.

    It is the main counterweight: heavy capital spending with low current returns could hurt CORZ if investors worry about profitability.

AMD Deal Turns Core Scientific Into an AI Data-Center Landlord

  • AMD signs 15-year, $14B AI infrastructure deal Core Scientific will lease up to 2.5 gigawatts of data-center capacity to AMD, starting with over 500 MW in 2027. The 15-year agreement could bring in more than $14 billion of contracted revenue, shifting the company from bitcoin mining to AI computing. This directly boosts future sales and makes earnings more predictable.

    This is the single biggest new event of the period and the main reason CORZ is moving.

  • KBW upgrades CORZ to Outperform, sees 35% upside After the AMD deal, KBW upgraded the stock and raised its price target to $28. The bank values the contracted AMD leases at about $23 per share and sees more upside if AMD reserves additional power. This analyst support gives investors confidence that the deal is worth more than the market initially priced in.

    It shows a major analyst re-rating the stock because of the AMD deal, reinforcing the positive impact.

  • BTIG raises price target to $38 on data-center momentum BTIG lifted its target to $38 from $33, pointing to fast data-center construction and strong demand for ready-to-use power. Core Scientific recently raised $3.3 billion in debt and expanded its power pipeline to 4.5 gigawatts, giving it the financial muscle to build for AI customers. This supports the growth story.

    It highlights analyst recognition of the company's expanding capacity and funding, which underpins the stock's rise.

  • AMD stock rally spotlights Core Scientific partnership AMD shares jumped 12.7% as AI chip demand rebounded, drawing fresh attention to its deal with Core Scientific. The agreement gives AMD access to over 500 megawatts of AI-ready capacity from 2027, with potential to expand fivefold. As AMD's AI business grows, so does the value of Core Scientific's role as its landlord.

    It shows how broader AI enthusiasm is spilling over to benefit CORZ through its AMD partnership.
