New Tenable OPEN for AI program enables customers to use preferred AI models, agents and tools to improve visibility, insight and action  | Source: Tenable Holdings, Inc.

COLUMBIA, Md., Oct. 20, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced the expansion of its open technology and partner ecosystem to accelerate integrated security workflows across the entire tech stack. Tenable OPEN for AI delivers validated, ready-to-use AI workflows, enabling organizations to use Tenable’s deep exposure intelligence with their preferred AI models, agents and tools. Tenable OPEN for AI launch partners include BeyondTrust, Cohesity, Command Zero, Corelight, Infoblox, Recorded Future, Securonix, SentinelOne, Setyl, Snyk, Sparkle In and Splunk.

As part of the Tenable Open Partner Exchange Network (OPEN), the company’s technology partner program, Tenable OPEN for AI connects the security stack and helps security teams use AI to investigate risk, prioritize exposures and take action faster.

“Tenable is the only exposure management provider offering a truly unrestricted, vendor-agnostic ecosystem of validated AI use cases, based on customer demand,” said Eric Doerr, chief product officer, Tenable. “By supporting both standardized MCP connectors and direct APIs, Tenable OPEN for AI provides security teams complete freedom to integrate their AI tools of choice and build custom, agentic workflows without artificial restrictions or forcing reliance on a single proprietary platform.”

By connecting the Tenable Hexa AI MCP Server with partner MCP servers via the AI tools customers already use, customers can interact with datasets across vendors simultaneously, unlocking cross-platform visibility and action, without custom software development. Each use case is available in two forms: as a documented workflow that security teams can replicate with the AI tool of their choice through the Tenable Hexa AI MCP Server, or as a ready-to-use skill on the CyberAgents Exchange, the vendor-agnostic AI agent marketplace powered by Tenable.

Featured OPEN for AI use cases available today include:

Cross-Platform Security Triage (SentinelOne): Engineered for security teams to investigate alerts, vulnerable assets and misconfigurations in natural language, from a single AI chat window.Network Threat & Blast Radius Mapping (Corelight): Designed to combine Corelight network telemetry with live Tenable asset context to rapidly triage active network threats and prioritize investigations and remediation based on the potential blast radius of exposed assets.Code-to-Runtime Risk Correlation (Snyk): Joins Snyk developer-first application security findings with Tenable runtime exposure data to quickly confirm whether code-level vulnerabilities are deployed in production.Identity-Enriched Exposure Triage (BeyondTrust): Combines BeyondTrust privileged account, session, and entitlement data with Tenable findings to risk-rank assets based on complete identity context.

“The ability to unite disjointed data across both endpoints and enterprise risk exposure and take coordinated, automated action transforms security teams,” said Melissa K. Smith, SVP Global Strategic Partnerships & Initiatives at SentinelOne. “Our partnership with Tenable OPEN for AI enables customers to see SentinelOne’s endpoint analysis and Tenable exposure intelligence side by side. Together, we’re delivering a cross-platform triage engine that prioritizes risk based on context-rich, real-world insights without requiring complex custom integrations.”

“Every SOC analyst knows the question that follows an alert: is this asset actually vulnerable?” said Robert Rossetti, Partner Engineer at Splunk. “Tenable OPEN for AI answers it inside the investigation. Analysts can, for example, ask questions in plain language and get Splunk alerts back with Tenable vulnerability context attached, so they can confirm whether a critical asset is under active attack and respond faster.”

“As AI assistants take on more of the day-to-day work of security operations, they need ground-truth network context to produce answers teams can act on,” said Matt Landry, Senior Vice President of Product Management, Infoblox. “By combining Infoblox network identity data with Tenable exposure intelligence through an open protocol, security teams can understand both what a device is and how exposed it is. This on-demand, correlated view gives AI-driven workflows a network source of truth for prioritizing the right assets and moving from signal to action faster.”

"Every exposure finding raises the same follow-up question: is anyone taking advantage of it?" said Dov Yoran, co-founder and CEO of Command Zero. "With Tenable OPEN for AI, a priority exposure finding from Tenable feeds directly into a Command Zero investigation, where it provides critical context and helps analysts prioritize response. Every step is recorded and reviewable, and the approved verdict goes back to Tenable so exposure and investigation teams eliminate the need to pivot between platforms."

Key Points:TENB breaks out of a bullish pennant on strong volume.Reclaiming the 200-week average strengthens bullish momentum.Initial target near $65.47 aligns with the record high.Support at $38.89 and $37.53 could sustain the breakout.A drop below $36.17 would weaken the bullish setup.Bullish Pennant Breakout Gains Momentum Tenable Holding, Inc. (TENB), a cybersecurity company, signaled a bullish continuation with an upside breakout from a pennant pattern last week, on a rally above the week’s high. The bullish continuation signal was accompanied by the highest volume in three weeks and followed the convergence of the 20-day and 50-day moving averages prior to the breakout. As the price range narrowed, the moving averages came together, reflecting the compression of price action also evident in the small symmetrical triangle that defines the pennant. During this consolidation buying and selling pressure converge before a breakout signals the next potential directional move.

TENB weekly chart shows decisive breakout of bullish pennant pattern Long-Term Breakout Adds Conviction The pennant formed during a bearish correction that followed the July peak of $43.67. At that high TENB was up 177% from the trend low of $15.73 in April. Last week’s breakout was decisive, with the significance of the signal enhanced by the concurrent reclaim of the 200-week moving average. Notably, the 200-week moving average was near the same price level during the breakout week, adding confluence to the bullish signal.

TENB daily chart shows close-up view Record High in Sight, With Higher Targets Ahead Together, these developments provide two meaningful bullish signals and suggest buyers could remain in control as TENB advances toward higher resistance targets. A classic measuring objective based on the pennant’s preceding advance points to possible upside targets near $65.47 or $104.18. The record high of $63.61 is also an eventual upside target. The first target near $65.47 is particularly notable because it aligns closely with the prior record high, creating an important potential resistance zone.

Support Levels That Could Preserve the Breakout For now, investors will be watching for the first pullback following the pennant breakout to identify potential trend-continuation opportunities. Areas to watch for support during weakness include a recent resistance shelf near $38.89 and the pennant breakout level of $37.53. A sustained dip below the 50-day moving average near $36.17 could be a cause for concern, as it would put TENB back inside the pennant’s consolidation range and weaken the breakout signal. Holding above these support levels would help preserve the bullish setup and keep the higher price targets in focus.

Latest news and analysis

COLUMBIA, Md., Oct. 08, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced the expansion of the CyberAgents Exchange, powered by Tenable, to further accelerate enterprise security adoption of open source AI agents, skills and MCP servers. Engineered by Tenable using OpenAI GPT cyber models, the CyberAgents Exchange AI Inspector (Exchange Inspector) evaluates selected AI components listed on the Exchange, including an enterprise-grade safety review, which is designed to help organizations more securely deploy in production environments.

The CyberAgents Exchange is an open-source, vendor-agnostic hub where security professionals discover and share AI agents, skills, MCP servers and playbooks built for cybersecurity. Exchange Inspector was developed as part of Tenable’s participation in the OpenAI Daybreak Defense Network.

Exchange Inspector is a three-part vetting process that begins with Tenable One AI Exposure's skills inspection engine, which is designed to detect malicious content, such as prompt-injection and the exposure of hardcoded secrets or customer data. The component then undergoes a frontier model assessment using OpenAI GPT cyber models, followed by expert review by Tenable's security research team.

Tenable carefully selects AI components that have demonstrated measurable results for Exchange Inspector vetting. Featured Exchange Inspector-vetted skills available today include:

SOC Hunter - an AI skill that brings structured, proactive threat hunting to incident response workstations. The contributor, Tenable’s enterprise security team, reports cutting hunt times by 75%. SOC Hunter leverages hypothesis-driven threat hunting using the LOCK pattern across SIEM, EDR, VM, CSPM, CASB and code search.Remediation Priority & Impact Agent - an AI skill that develops a daily prioritization plan for vulnerability remediation by combining live exposure data from Tenable, CISA KEV exploitation, MITRE ATT&CK and attack paths. We estimate the Remediation Priority & Impact Agent can reduce analyst triage time by up to 20X per cycle.Splunk Tenable Cloud Security Skill - a multi-model skill that enables security teams to query and triage Tenable One Cloud Security posture findings already ingested in Splunk using production-safe, count-first SPL via the official Splunk MCP Server, reclaiming dozens of hours of analysts’ time every week.
“With Tenable, security teams can accelerate AI innovation while maintaining rigorous security standards,” said Vlad Korsunsky, Chief Technology Officer, Tenable. “Leveraging Tenable One AI Exposure’s advanced AI discovery engine and frontier assessment using OpenAI GPT cyber models, the Exchange Inspector provides an additional layer of review for this rapidly growing subset of agents, skills and MCP servers before deployment. The CyberAgents Exchange symbolizes trusted AI innovation, enabling CISOs and security teams to deploy AI more safely across the enterprise.”

“The cybersecurity community has come together in a truly meaningful way on the CyberAgents Exchange," said McCall McIntyre, Head of Global Cyber Partnerships, OpenAI. "We are excited to work with Tenable on this important initiative to help deliver the trust layer required to more safely scale agentic AI across the enterprise.”

Read today’s blog, “Inside the Exchange Inspector: How Tenable uses OpenAI GPT cyber models to review open-source AI agents,” for more details on the CyberAgents Exchange components that have been Exchange Inspector-vetted.

AI component inspection is powered by Tenable One AI Exposure – the same skills inspection technology that can secure the agents already running across your environment. Request a demo: http://tenable.com/cyberagents-exchange/try-ai-exposure

Artificial intelligence (AI) is a powerful technology with the potential to dramatically improve economic productivity. But over the last few months, AI agents developed by labs like OpenAI have escaped test environments and autonomously launched cyberattacks on corporate and government websites, raising concerns about the safety of critical digital infrastructure.

Understandably, cybersecurity is now a top priority for most organizations, so some of the best providers have seen their values soar. Tenable (TENB +2.66%) stock, for instance, is now sitting on a year-to-date gain of 48.6% (as of the market close on Tuesday, Sept. 29), outperforming the S&P 500 (^GSPC +0.76%) by a factor of four.

Tenable specializes in exposure management, a proactive form of enterprise-grade cybersecurity that identifies vulnerabilities in corporate networks before cyberattackers can exploit them. The company is likely to see growing demand for its products over the next few years, so its stock could be a great long-term investment, especially since it trades at a steep discount to its rivals.

Exposure management is critical in the AI era Tenable owns Nessus, the cybersecurity industry's most widely deployed, most accurate platform for identifying vulnerabilities. It scans operating systems, networks, and devices around the clock for vulnerabilities in their defenses so they can be fixed before being exploited. But this tool alone isn't enough in the AI era, so Tenable offers an expanding portfolio of even more advanced products.

These products are available under a comprehensive platform called Tenable One, which fulfills every exposure management requirement an enterprise might have. It's powered by an agentic AI engine called Hexa AI, which orchestrates a fleet of AI agents to handle tasks like building risk dashboards, running scans, and scheduling remediation. It learns how corporate assets interact, so it's equipped with enough context to flag potential vulnerabilities.

Tenable One also protects enterprises that are deploying AI. It features a tool called AI Exposure, which continuously monitors how employees use AI applications and which critical assets those applications can access, enabling it to identify potential vulnerabilities. It can also uncover instances of prompt injection, in which hackers trick internal AI applications into handing over sensitive data by disguising their malicious requests as legitimate instructions.

Tenable One accounted for half of Tenable's new sales in the second quarter of 2026 (ended June 30), indicating that enterprises are clearly shifting toward holistic platforms rather than piecing together individual products.

Revenue growth could accelerate from here Tenable's business is growing at a relatively modest pace, partly because management is focusing on profitability by carefully managing costs. The company generated $268.5 million in revenue during the second quarter, which topped management's guidance range of $263 million to $266 million but represented a year-over-year increase of just 8.6%.

Tenable had $195.3 million in total operating expenses during the quarter, down from $200.3 million in the year-ago quarter. That included cuts to growth-oriented costs such as sales and marketing, which were likely a headwind to customer acquisition and revenue. But on a positive note, it resulted in a generally accepted accounting principles (GAAP) net income of $3.8 million, a big improvement from the $14.7 million net loss from the year-ago quarter.

Tenable also generated a healthy profit of $57.9 million on an adjusted (non-GAAP) basis, which excludes one-off and noncash expenses like stock-based compensation. That was up 40% year over year.

By continuing to improve the bottom line, Tenable will have more flexibility to reinvest in the business without having to raise additional capital from investors or tap debt financing. Given the scale of the AI opportunity, I predict management will soon begin spending more aggressively on areas such as marketing, research, and development to capture as much market share as possible. That could accelerate the company's revenue growth.

Tenable is one of the cheapest stocks in the cybersecurity industry Tenable stock is trading at a price-to-sales (P/S) ratio of just 3.9, so it's already much cheaper than the Nasdaq-100, which has a P/S ratio of 6.4. It's also substantially cheaper than each of its closest rivals, CrowdStrike, Palo Alto Networks, and Zscaler, which trade at P/S ratios of between 9.5 and 50.1.

CRWD PS Ratio data by YCharts

Each of those companies generates more revenue than Tenable and is growing faster, so they deserve premium valuations. CrowdStrike, for example, increased its annual recurring revenue by 25% to $5.8 billion during its most recent quarter. But that said, I don't think CrowdStrike's P/S ratio should be 12 times higher than Tenable's P/S ratio.

I'm not suggesting Tenable's P/S ratio will ever climb to above 50, but its current valuation certainly leaves room for upside. As a result, investors seeking exposure to the cybersecurity industry amid the growing threat from AI might want to consider buying Tenable, particularly while it's cheaper than both the market and its main rivals.

Taking full advantage of the stock market and investing with confidence are common goals for new and old investors, and Zacks Premium offers many different ways to do both.

The research service features daily updates of the Zacks Rank and Zacks Industry Rank, full access to the Zacks #1 Rank List, Equity Research reports, and Premium stock screens, all of which will help you become a smarter, more confident investor.

Zacks Premium also includes the Zacks Style Scores.

What are the Zacks Style Scores? Developed alongside the Zacks Rank, the Zacks Style Scores are a group of complementary indicators that help investors pick stocks with the best chances of beating the market over the next 30 days.

Based on their value, growth, and momentum characteristics, each stock is assigned a rating of A, B, C, D, or F. The better the score, the better chance the stock will outperform; an A is better than a B, a B is better than a C, and so on.

The Style Scores are broken down into four categories:

Value ScoreValue investors love finding good stocks at good prices, especially before the broader market catches on to a stock's true value. Utilizing ratios like P/E, PEG, Price/Sales, Price/Cash Flow, and many other multiples, the Value Style Score identifies the most attractive and most discounted stocks.

Growth ScoreGrowth investors are more concerned with a stock's future prospects, and the overall financial health and strength of a company. Thus, the Growth Style Score analyzes characteristics like projected and historic earnings, sales, and cash flow to find stocks that will see sustainable growth over time.

Momentum ScoreMomentum investors, who live by the saying "the trend is your friend," are most interested in taking advantage of upward or downward trends in a stock's price or earnings outlook. Utilizing one-week price change and the monthly percentage change in earnings estimates, among other factors, the Momentum Style Score can help determine favorable times to buy high-momentum stocks.

VGM ScoreWhat if you like to use all three types of investing? The VGM Score is a combination of all Style Scores, making it one of the most comprehensive indicators to use with the Zacks Rank. It rates each stock on their combined weighted styles, which helps narrow down the companies with the most attractive value, best growth forecast, and most promising momentum.

How Style Scores Work with the Zacks Rank The Zacks Rank, which is a proprietary stock-rating model, employs earnings estimate revisions, or changes to a company's earnings expectations, to make building a winning portfolio easier.

It's highly successful, with #1 (Strong Buy) stocks producing an unmatched +23.8% average annual return since 1988. That's more than double the S&P 500. But because of the large number of stocks we rate, there are over 200 companies with a Strong Buy rank, plus another 600 with a #2 (Buy) rank, on any given day.

With more than 800 top-rated stocks to choose from, it can certainly feel overwhelming to pick the ones that are right for you and your investing journey.

That's where the Style Scores come in.

You want to make sure you're buying stocks with the highest likelihood of success, and to do that, you'll need to pick stocks with a Zacks Rank #1 or #2 that also have Style Scores of A or B. If you like a stock that only has a #3 (Hold) rank, it should also have Scores of A or B to guarantee as much upside potential as possible.

The direction of a stock's earnings estimate revisions should always be a key factor when choosing which stocks to buy, since the Scores were created to work together with the Zacks Rank.

A stock with a #4 (Sell) or #5 (Strong Sell) rating, for instance, even one with Scores of A and B, will still have a declining earnings forecast, and a greater chance its share price will fall too.

Thus, the more stocks you own with a #1 or #2 Rank and Scores of A or B, the better.

Stock to Watch: Tenable (TENB - Free Report) Tenable Holdings provides exposure management solutions that extend vulnerability management to risk assessment and prioritization across IT, cloud, OT, web apps, identity systems and emerging AI assets. The platform unifies visibility, context and action so organizations can identify and close cybersecurity gaps.

TENB is a #3 (Hold) on the Zacks Rank, with a VGM Score of B.

Additionally, the company could be a top pick for growth investors. TENB has a Growth Style Score of A, forecasting year-over-year earnings growth of 24.5% for the current fiscal year.

10 analysts revised their earnings estimate higher in the last 60 days for fiscal 2026, while the Zacks Consensus Estimate has increased $0.01 to $1.98 per share. TENB also boasts an average earnings surprise of +12.7%.

With a solid Zacks Rank and top-tier Growth and VGM Style Scores, TENB should be on investors' short list.

COLUMBIA, Md., Sept. 10, 2026 (GLOBE NEWSWIRE) -- Tenable Holdings, Inc. (Nasdaq: TENB) (“Tenable”), the exposure management company, announced today the pricing of $725.0 million aggregate principal amount of 0.25% Convertible Senior Notes due 2031 (the “notes”) in a private placement (the “offering”) only to persons reasonably believed to be “qualified institutional buyers” pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The offering was upsized from the previously announced offering size of $650.0 million aggregate principal amount of the notes. Tenable has also granted the initial purchasers of the notes an option to purchase, during a 13-day period beginning on, and including, the date on which the notes are first issued, up to an additional $75.0 million aggregate principal amount of the notes. The sale of the notes to the initial purchasers is expected to close on September 15, 2026, subject to customary closing conditions.

The notes will be general senior unsecured obligations of Tenable. The notes will accrue interest payable semiannually in arrears on March 15 and September 15 of each year, beginning on March 15, 2027, at a rate of 0.25% per year. The notes will mature on September 15, 2031, unless earlier converted, redeemed or repurchased.

Tenable estimates that the net proceeds from the offering will be approximately $705.6 million (or approximately $778.8 million if the initial purchasers exercise their option to purchase additional notes in full), after deducting the initial purchasers’ discounts and estimated offering expenses. Tenable expects to use the net proceeds from the offering (i) to pay the approximately $58.1 million cost of the capped call transactions described below, (ii) to repurchase approximately $170.5 million of its common stock concurrently with the pricing of the notes as described below, (iii) to pay the cost of repaying in full the term loans under Tenable’s senior secured credit facility (the “credit facility”) and (iv) for general corporate purposes, which may include additional share repurchases, acquisitions or strategic investments in complementary businesses or technologies, working capital, operating expenses, capital expenditures and general and administrative expenses. If the initial purchasers exercise their option to purchase additional notes, Tenable expects to use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions, with the remainder to be used for general corporate purposes.

The notes will be convertible at the option of the holders in certain circumstances. Upon conversion, Tenable will pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of Tenable’s common stock or a combination of cash and shares of Tenable’s common stock, at Tenable’s election, in respect of the remainder, if any, of Tenable’s conversion obligation in excess of the aggregate principal amount of the notes being converted.

The conversion rate will initially be 22.3005 shares of Tenable’s common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $44.84 per share of Tenable’s common stock). The initial conversion price represents a premium of approximately 40.0% over the last reported sale price of $32.03 per share of Tenable’s common stock on September 10, 2026. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date or if Tenable delivers a notice of redemption, it will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or convert its notes called (or deemed called, in the case of an optional redemption) for redemption during the related redemption period, as the case may be.

Tenable may not redeem the notes prior to September 20, 2029, except in the event of a cleanup redemption described below. Tenable may redeem for cash all or any portion of the notes (subject to certain limitations), at its option, on a redemption date on or after September 20, 2029 and before the 31st scheduled trading day immediately prior to the maturity date if the last reported sale price of Tenable’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which Tenable provides the related notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. In addition, subject to certain conditions, Tenable may redeem for cash all, but not less than all, of the notes at any time before the 31st scheduled trading day immediately prior to the maturity date if the aggregate principal amount of the notes that remains outstanding at such time is less than $80.0 million at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

If Tenable undergoes a “fundamental change” (as defined in the indenture that will govern the notes) then, subject to certain conditions and exceptions, holders may require Tenable to repurchase for cash all or any portion of their notes at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

In connection with the pricing of the notes, Tenable entered into privately negotiated capped call transactions with certain of the initial purchasers or affiliates thereof and certain other financial institutions (the “option counterparties”). The capped call transactions cover, subject to customary adjustments substantially similar to those applicable to the notes, the number of shares of Tenable’s common stock initially underlying the notes. The capped call transactions are expected generally to reduce the potential dilution to Tenable’s common stock upon any conversion of notes and/or offset any cash payments Tenable is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. If the initial purchasers exercise their option to purchase additional notes, Tenable expects to use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions with the option counterparties.

The cap price of the capped call transactions relating to the notes will initially be $64.06, which represents a premium of 100.0% over the last reported sale price of Tenable’s common stock on the Nasdaq Global Select Market on September 10, 2026, and is subject to certain adjustments under the terms of the capped call transactions.

In connection with establishing their initial hedges of the capped call transactions, Tenable expects that the option counterparties or their respective affiliates will purchase shares of Tenable’s common stock and/or enter into various derivative transactions with respect to Tenable’s common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of Tenable’s common stock or the notes at that time.

In addition, Tenable expects that the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Tenable’s common stock and/or purchasing or selling Tenable’s common stock or other securities of Tenable in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so during any observation period related to a conversion of notes, following any redemption of the notes or any repurchase of the notes upon a fundamental change, or, to the extent Tenable exercises the relevant election under the capped call transactions, following any other repurchase of the notes). This activity could also cause or avoid an increase or a decrease in the market price of Tenable’s common stock or the notes, which could affect the ability of a holder of notes to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the number of shares, if any, and value of the consideration that a holder of notes will receive upon conversion of the notes.

Tenable expects to use approximately $170.5 million of the net proceeds from the offering to repurchase approximately 5.3 million shares of its common stock concurrently with the pricing of the notes in privately negotiated transactions effected with or through one of the initial purchasers of the notes or its affiliate at a purchase price per share equal to the last reported sale price of Tenable’s common stock on the Nasdaq Global Select Market on September 10, 2026. These repurchases could increase (or reduce the size of any decrease in) the market price of Tenable’s common stock or the notes prior to, concurrently with or shortly after the pricing of the notes and could have resulted in a higher effective conversion price for the notes. Tenable may also conduct further repurchases of its common stock after the offering is completed pursuant to its previously authorized share repurchase program.

The notes were only offered to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act by means of a private offering memorandum. The notes and any shares of Tenable’s common stock issuable upon conversion of the notes have not been and will not be registered under the Securities Act, any state securities laws or the securities laws of any other jurisdiction, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

This press release is neither an offer to sell nor a solicitation of an offer to buy any of these securities nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification thereof under the securities laws of any such state or jurisdiction.

COLUMBIA, Md., Sept. 10, 2026 (GLOBE NEWSWIRE) -- Tenable Holdings, Inc. (Nasdaq: TENB) (“Tenable”), the exposure management company, today announced that it intends to offer, subject to market conditions and other factors, $650.0 million aggregate principal amount of Convertible Senior Notes due 2031 (the “notes”) in a private placement (the “offering”) only to persons reasonably believed to be “qualified institutional buyers” pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). Tenable also intends to grant the initial purchasers of the notes an option to purchase, during a 13-day period beginning on, and including, the date on which the notes are first issued, up to an additional $65.0 million aggregate principal amount of the notes.

The notes will be general senior unsecured obligations of Tenable and will accrue interest payable semiannually in arrears. Upon conversion, Tenable will pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of Tenable’s common stock or a combination of cash and shares of Tenable’s common stock, at Tenable’s election, in respect of the remainder, if any, of Tenable’s conversion obligation in excess of the aggregate principal amount of the notes being converted. The interest rate, initial conversion rate and other terms of the notes will be determined at the time of the pricing of the notes.

Tenable expects to use the net proceeds from the offering (i) to pay the cost of the privately negotiated capped call transactions described below, (ii) to repurchase up to $200.0 million of shares of Tenable’s common stock concurrently with the pricing of the notes as described below, (iii) to repay in full the term loans under Tenable’s senior secured credit facility (the “credit facility”), and (iv) for general corporate purposes, which may include additional share repurchases, acquisitions or strategic investments in complementary businesses or technologies, working capital, operating expenses, capital expenditures and general and administrative expenses. Following the closing of the offering, Tenable intends to enter into a new senior secured revolving credit facility. However, there is no assurance as to the terms of such facility or that Tenable will ultimately enter into such an arrangement. If the initial purchasers exercise their option to purchase additional notes, Tenable expects to use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions, with the remainder to be used for general corporate purposes.

In connection with the pricing of the notes, Tenable expects to enter into privately negotiated capped call transactions with one or more of the initial purchasers or affiliates thereof and/or other financial institutions (the “option counterparties”). The capped call transactions will cover, subject to customary adjustments substantially similar to those applicable to the notes, the number of shares of Tenable’s common stock that will initially underlie the notes. The capped call transactions are expected generally to reduce the potential dilution to Tenable’s common stock upon any conversion of notes and/or offset any cash payments Tenable is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. If the initial purchasers exercise their option to purchase additional notes, Tenable expects to use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions with the option counterparties.

In connection with establishing their initial hedges of the capped call transactions, Tenable expects that the option counterparties or their respective affiliates will purchase shares of Tenable’s common stock and/or enter into various derivative transactions with respect to Tenable’s common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of Tenable’s common stock or the notes at that time.

In addition, Tenable expects that the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Tenable’s common stock and/or purchasing or selling Tenable’s common stock or other securities of Tenable in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so during any observation period related to a conversion of notes, following any redemption of the notes or any repurchase of the notes upon a fundamental change, or, to the extent Tenable exercises the relevant election under the capped call transactions, following any other repurchase of the notes). This activity could also cause or avoid an increase or a decrease in the market price of Tenable’s common stock or the notes, which could affect the ability of a holder of notes to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the number of shares, if any, and value of the consideration that a holder of notes will receive upon conversion of the notes.

Tenable expects to use up to $200.0 million of the net proceeds from the offering to repurchase shares of its common stock concurrently with the pricing of the notes in privately negotiated transactions effected with or through one of the initial purchasers of the notes or its affiliate. These repurchases could increase (or reduce the size of any decrease in) the market price of Tenable’s common stock or the notes prior to, concurrently with or shortly after the pricing of the notes and could result in a higher effective conversion price for the notes. Tenable expects the purchase price per share in such transactions to equal the last reported sale price per share of Tenable’s common stock on The Nasdaq Global Select Market on the date of the pricing of the notes. Tenable may also conduct further repurchases of its common stock after the offering is completed pursuant to its previously authorized share repurchase program.

The notes and any shares of Tenable’s common stock issuable upon conversion of the notes have not been and will not be registered under the Securities Act, any state securities laws or the securities laws of any other jurisdiction, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

This press release is neither an offer to sell nor a solicitation of an offer to buy any of these securities nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification thereof under the securities laws of any such state or jurisdiction.

CyberAgents Exchange AI Inspector combines OpenAI GPT cyber models with Tenable security expertise to help teams evaluate AI agents, skills, MCP servers and multi-agent playbooks before deployment  | Source: Tenable Holdings, Inc.

COLUMBIA, Md., Sept. 03, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced that it is collaborating with OpenAI to create the CyberAgents Exchange AI Inspector (Exchange Inspector), a new security review process for AI agents, skills, MCP servers and multi-agent playbooks available through the CyberAgents Exchange, powered by Tenable.

Unveiled today at OpenAI’s Intelligence at Work: Cyber Summit, Exchange Inspector combines frontier assessment, skills inspection powered by Tenable One AI Exposure and expert review from Tenable researchers, to enable security teams to safely accelerate enterprise adoption of agentic AI. The collaboration grew from Tenable’s participation in the OpenAI Daybreak Defense Network. Exchange Inspector is expected to be available in September.

Launched in August 2026, the CyberAgents Exchange is an open-source, cybersecurity-native registry for AI agents, skills, MCP servers and multi-agent playbooks in the current market. Following its recent SWARM build event, hosted by Tenable at Black Hat USA, the Exchange now includes more than 100 community-submitted AI components.

“Agentic AI will only reach its potential in the enterprise if security teams can trust the components being introduced into their environments,” said Eric Doerr, chief product officer at Tenable. “By combining OpenAI GPT cyber models with Tenable’s security expertise and researcher review, we’re building a more rigorous way to inspect community-built AI components before they’re used in enterprise environments. This is an important step in applying frontier AI to help defenders identify and prioritize risk across the growing agent ecosystem.”

The Intelligence at Work: Cyber Summit event convened top cybersecurity leaders to discuss how frontier AI can help defenders move faster, strengthen enterprise resilience and turn threat findings into actionable fixes at enterprise scale. Hosted by OpenAI, the event highlighted defensive security applications being developed with cybersecurity companies, including ways to bring advanced cyber reasoning into the platforms and workflows defenders already use.

For new and old investors, taking full advantage of the stock market and investing with confidence are common goals. Zacks Premium provides lots of different ways to do both.

The popular research service can help you become a smarter, more self-assured investor, giving you access to daily updates of the Zacks Rank and Zacks Industry Rank, the Zacks #1 Rank List, Equity Research reports, and Premium stock screens.

Zacks Premium also includes the Zacks Style Scores.

What are the Zacks Style Scores? Developed alongside the Zacks Rank, the Zacks Style Scores are a group of complementary indicators that help investors pick stocks with the best chances of beating the market over the next 30 days.

Based on their value, growth, and momentum characteristics, each stock is assigned a rating of A, B, C, D, or F. The better the score, the better chance the stock will outperform; an A is better than a B, a B is better than a C, and so on.

The Style Scores are broken down into four categories:

Value ScoreValue investors love finding good stocks at good prices, especially before the broader market catches on to a stock's true value. Utilizing ratios like P/E, PEG, Price/Sales, Price/Cash Flow, and many other multiples, the Value Style Score identifies the most attractive and most discounted stocks.

Growth ScoreGrowth investors, on the other hand, are more concerned with a company's financial strength and health, and its future outlook. The Growth Style Score examines things like projected and historic earnings, sales, and cash flow to find stocks that will experience sustainable growth over time.

Momentum ScoreMomentum traders and investors live by the saying "the trend is your friend." This investing style is all about taking advantage of upward or downward trends in a stock's price or earnings outlook. Employing factors like one-week price change and the monthly percentage change in earnings estimates, the Momentum Style Score can indicate favorable times to build a position in high-momentum stocks.

VGM ScoreIf you want a combination of all three Style Scores, then the VGM Score will be your friend. It rates each stock on their combined weighted styles, helping you find the companies with the most attractive value, best growth forecast, and most promising momentum. It's also one of the best indicators to use with the Zacks Rank.

How Style Scores Work with the Zacks Rank The Zacks Rank, which is a proprietary stock-rating model, employs earnings estimate revisions, or changes to a company's earnings expectations, to make building a winning portfolio easier.

#1 (Strong Buy) stocks have produced an unmatched +23.8% average annual return since 1988, which is more than double the S&P 500's performance over the same time frame. However, the Zacks Rank examines a ton of stocks, and there can be more than 200 companies with a Strong Buy rank, and another 600 with a #2 (Buy) rank, on any given day.

This totals more than 800 top-rated stocks, and it can be overwhelming to try and pick the best stocks for you and your portfolio.

That's where the Style Scores come in.

You want to make sure you're buying stocks with the highest likelihood of success, and to do that, you'll need to pick stocks with a Zacks Rank #1 or #2 that also have Style Scores of A or B. If you like a stock that only has a #3 (Hold) rank, it should also have Scores of A or B to guarantee as much upside potential as possible.

As mentioned above, the Scores are designed to work with the Zacks Rank, so any change to a company's earnings outlook should be a deciding factor when picking which stocks to buy.

A stock with a #4 (Sell) or #5 (Strong Sell) rating, for instance, even one with Scores of A and B, will still have a declining earnings forecast, and a greater chance its share price will fall too.

Thus, the more stocks you own with a #1 or #2 Rank and Scores of A or B, the better.

Stock to Watch: Tenable (TENB - Free Report) Tenable Holdings provides exposure management solutions that extend vulnerability management to risk assessment and prioritization across IT, cloud, OT, web apps, identity systems and emerging AI assets. The platform unifies visibility, context and action so organizations can identify and close cybersecurity gaps.

TENB is a #3 (Hold) on the Zacks Rank, with a VGM Score of B.

Additionally, the company could be a top pick for growth investors. TENB has a Growth Style Score of A, forecasting year-over-year earnings growth of 24.5% for the current fiscal year.

Nine analysts revised their earnings estimate higher in the last 60 days for fiscal 2026, while the Zacks Consensus Estimate has increased $0.01 to $1.98 per share. TENB also boasts an average earnings surprise of +12.7%.

With a solid Zacks Rank and top-tier Growth and VGM Style Scores, TENB should be on investors' short list.

A month has gone by since the last earnings report for Tenable (TENB - Free Report) . Shares have added about 15.6% in that time frame, outperforming the S&P 500.

But investors have to be wondering, will the recent positive trend continue leading up to its next earnings release, or is Tenable due for a pullback? Before we dive into how investors and analysts have reacted as of late, let's take a quick look at the latest earnings report in order to get a better handle on the important drivers.

TENB Q2 Earnings Beat on Tenable One Momentum, Outlook RaisedTenable Holdings reported strong second-quarter 2026 results, with non-GAAP earnings of 51 cents per share, up 50% year over year. The figure beat the Zacks Consensus Estimate of 47 cents by 8.51%. Revenues rose 8.6% year over year to $268.5 million and surpassed the consensus mark of $265 million by 1.32%.

Results were driven by record adoption of the Tenable One platform, which represented 50% of new business during the quarter, up from 40% in the year-ago period.

TENB Benefits From Platform AdoptionRevenue growth was supported by strong expansion within existing accounts and continued strength in renewals. Professional services also contributed ahead of expectations. Recurring revenues remained high at 95% of total revenues compared with 96% in the year-ago period.

Tenable continued expanding its customer base, adding 381 new enterprise platform customers during the quarter, along with 32 net new six-figure customers. The net dollar expansion rate improved to 106% from 105% in the prior quarter, marking the first quarter-over-quarter increase in the metric since the first quarter of 2022.

Tenable Sees AI as a Long-Term TailwindThe heightened AI-driven threat environment following the Mythos development is accelerating customer demand for exposure management platforms capable of prioritizing and remediating cyber risk at speed. Tenable Hexa AI, the company's agentic engine within Tenable One, saw strong early traction, with more than 80% of users submitting prompts and nearly half using it to take action rather than simply consume information.

The company also expanded its Tenable One AI Exposure offering to include coverage for Gemini alongside existing coverage for Claude, ChatGPT and Copilot. Tenable deepened its partnerships with Anthropic through Project Glasswing and with OpenAI through its Daybreak Cyber Partner Program during the quarter.

TENB Maintains Healthy ProfitabilityNon-GAAP gross margin was 81.4% compared with 82% in the year-ago period, within the company's typical historical range. Non-GAAP operating income increased 38.8% year over year to $66.2 million. The non-GAAP operating margin expanded 540 basis points to 24.7%.

GAAP income from operations was $12.4 million compared with a loss of $7.4 million in the year-ago quarter, while GAAP operating margin was 4.6% versus negative 3% a year earlier.

Tenable Generates Strong Cash FlowThe company ended the quarter with $298.2 million in cash and short-term investments, down from $360.3 million as of March 31, 2026, primarily reflecting share repurchase activity.

Long-term debt was $353 million, down slightly on a sequential basis from $353.6 million as of March 31, 2026. Unlevered free cash flow was $45.3 million, or 16.9% of revenues compared with $44.3 million in the year-ago quarter. During the quarter, Tenable repurchased 5.2 million shares for $100 million and had $108 million remaining under its existing authorization.

How Have Estimates Been Moving Since Then?It turns out, estimates revision have trended upward during the past month.

VGM ScoresCurrently, Tenable has a great Growth Score of A, though it is lagging a lot on the Momentum Score front with a D. Following the exact same course, the stock was allocated a score of D on the value side, putting it in the bottom 40% for this investment strategy.

Overall, the stock has an aggregate VGM Score of C. If you aren't focused on one strategy, this score is the one you should be interested in.

OutlookEstimates have been trending upward for the stock, and the magnitude of these revisions looks promising. Notably, Tenable has a Zacks Rank #3 (Hold). We expect an in-line return from the stock in the next few months.

Performance of an Industry PlayerTenable is part of the Zacks Internet - Software industry. Over the past month, F5 Networks (FFIV - Free Report) , a stock from the same industry, has gained 5.5%. The company reported its results for the quarter ended June 2026 more than a month ago.

Tenable now delivers greater risk visibility and governance across an expanded AI attack surface created by increased adoption of LLMs, MCPs and AI tools August 04, 2026 09:00 ET  | Source: Tenable Holdings, Inc.

LAS VEGAS, Aug. 04, 2026 (GLOBE NEWSWIRE) -- Black Hat USA Booth #2639 — Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced enhanced AI security capabilities within the Tenable One Exposure Management Platform. Tenable One AI Exposure now delivers expanded platform coverage with support for Google Gemini, extending its coverage across major LLMs: Google Gemini, Anthropic Claude, OpenAI ChatGPT Enterprise and Microsoft Copilot. The release also extends discovery to all major Model Context Protocol (MCP) deployments and AI-native Integrated Development Environment (IDE) tools. Together, these capabilities give security teams a more complete view of where AI is being used, what risk it creates and where action is needed.

The rapid adoption of AI across the enterprise has created a critical AI exposure gap, a largely invisible risk that emerges across interconnected applications, infrastructure, identities and data. Underscoring this risk, Tenable detected 457 million AI-related security issues across more than 7,000 organizations, averaging 62,000 exposures per organization over a 30-day period. Traditional security tools leave security teams blind to high-impact attack paths, forcing them into a reactive loop rather than preemptively reducing AI risk.

Tenable One continuously discovers AI across endpoints, cloud and LLM applications, including both authorized and shadow AI. It inventories AI assets with the Tenable Exposure Graph, Tenable's data lake that aggregates massive volumes of security data to help organizations map, analyze and prevent cyber risks. Tenable One reduces real-world AI risk by securing the environments where AI runs and hardening AI workloads before they can be exploited. With these new advancements, Tenable One enables organizations to gain better visibility, context and control to manage AI risk while being able to govern AI use, enforce policies and prevent cyber exposures.

New AI security capabilities within Tenable One include:

Google Gemini Coverage: Tenable One now delivers visibility and governance for Google Gemini including monitoring of user interactions and prompt responses, policy enforcement, and detection of malicious activity and inappropriate usage.Enhanced AI Visibility: Tenable One now doubles its coverage of sanctioned and shadow AI, supporting MCPs, AI-native IDEs (such as Cursor, Windsurf and Trae) and AI-enabled browser extensions.Operationalized Remediation: Organizations can remediate faster by creating tickets directly in Jira and ServiceNow or alerting users on policy violations by sending automated email notifications, Slack or Teams messages. “The massive volume of AI exposures confirms the operational reality that authorized and unauthorized AI is deployed faster than security teams can govern it,” said Eric Doerr, Chief Product Officer, Tenable. “There’s no denying that AI attack surfaces are making defenders’ jobs even harder, and legacy or siloed cybersecurity tools simply don’t cut it. With today’s expansion to include Google Gemini, MCP and AI-native IDE deployments, Tenable is the only exposure management platform delivering unified AI visibility and governance across all major LLMs, software, and tools.”

Tenable One brings together two distinct AI capabilities. Tenable AI Exposure helps organizations discover, assess and secure how AI is being used across their environments. Tenable Hexa AI is the platform’s agentic engine, using AI to coordinate agents, automate security tasks and accelerate remediation. Put simply, AI Exposure helps organizations secure their use of AI, while Hexa helps them use AI to improve security operations. Together, they advance Tenable’s preemptive security strategy by helping organizations reduce AI-related risk and act on cyber exposure more efficiently.

Visit the Tenable booth #2639 this week at Black Hat USA, August 4-7, 2026, to see Tenable One in action.

Key Takeaways TENB beat Q2 EPS and revenue estimates as Tenable One accounted for 50% of new business.Tenable added 381 enterprise platform customers and improved its net dollar expansion rate to 106%.TENB saw strong early traction for Hexa AI, with most users submitting prompts and many taking action. Tenable Holdings (TENB - Free Report) reported strong second-quarter 2026 results, with non-GAAP earnings of 51 cents per share, up 50% year over year. The figure beat the Zacks Consensus Estimate of 47 cents by 8.51%. Revenues rose 8.6% year over year to $268.5 million and surpassed the consensus mark of $265 million by 1.32%.

Results were driven by record adoption of the Tenable One platform, which represented 50% of new business during the quarter, up from 40% in the year-ago period.

TENB Benefits From Platform AdoptionRevenue growth was supported by strong expansion within existing accounts and continued strength in renewals. Professional services also contributed ahead of expectations. Recurring revenues remained high at 95% of total revenues compared with 96% in the year-ago period.

Tenable continued expanding its customer base, adding 381 new enterprise platform customers during the quarter, along with 32 net new six-figure customers. The net dollar expansion rate improved to 106% from 105% in the prior quarter, marking the first quarter-over-quarter increase in the metric since the first quarter of 2022.

Tenable Sees AI as a Long-Term TailwindThe heightened AI-driven threat environment following the Mythos development is accelerating customer demand for exposure management platforms capable of prioritizing and remediating cyber risk at speed. Tenable Hexa AI, the company's agentic engine within Tenable One, saw strong early traction, with more than 80% of users submitting prompts and nearly half using it to take action rather than simply consume information.

The company also expanded its Tenable One AI Exposure offering to include coverage for Gemini alongside existing coverage for Claude, ChatGPT and Copilot. Tenable deepened its partnerships with Anthropic through Project Glasswing and with OpenAI through its Daybreak Cyber Partner Program during the quarter.

TENB Maintains Healthy ProfitabilityNon-GAAP gross margin was 81.4% compared with 82% in the year-ago period, within the company's typical historical range. Non-GAAP operating income increased 38.8% year over year to $66.2 million. The non-GAAP operating margin expanded 540 basis points to 24.7%.

GAAP income from operations was $12.4 million compared with a loss of $7.4 million in the year-ago quarter, while GAAP operating margin was 4.6% versus negative 3% a year earlier.

Tenable Generates Strong Cash FlowThe company ended the quarter with $298.2 million in cash and short-term investments, down from $360.3 million as of March 31, 2026, primarily reflecting share repurchase activity.

Long-term debt was $353 million, down slightly on a sequential basis from $353.6 million as of March 31, 2026. Unlevered free cash flow was $45.3 million, or 16.9% of revenues compared with $44.3 million in the year-ago quarter. During the quarter, Tenable repurchased 5.2 million shares for $100 million and had $108 million remaining under its existing authorization.

Zacks Rank & Stocks to ConsiderTenable currently carries a Zacks Rank #3 (Hold).

Some better-ranked stocks in the broader Zacks Computer and Technology sector are Analog Devices (ADI - Free Report) , Applied Materials (AMAT - Free Report) and Cisco Systems (CSCO - Free Report) , each carrying a Zacks Rank #2 (Buy) at present. You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

Shares of Analog Devices have rallied 37.1% year to date. The Zacks Consensus Estimate for ADI’s fiscal 2026 earnings is pegged at $12.42 per share, up by 10 cents over the past 30 days, indicating an increase of 59.4% year over year.

Shares of Applied Materials have skyrocketed 101.1% year to date. The Zacks Consensus Estimate for AMAT’s fiscal 2026 earnings is pegged at $12.14 per share, up by 4 cents over the past 30 days, indicating a rise of 28.9% year over year.

Cisco Systems shares have surged 48.7% year to date. The Zacks Consensus Estimate for CSCO’s fiscal 2026 earnings is pegged at $4.28 per share, unchanged over the past 30 days, indicating an increase of 12.3% year over year.

Tenable (TENB - Free Report) came out with quarterly earnings of $0.51 per share, beating the Zacks Consensus Estimate of $0.47 per share. This compares to earnings of $0.34 per share a year ago. These figures are adjusted for non-recurring items.

This quarterly report represents an earnings surprise of +8.51%. A quarter ago, it was expected that this cybersecurity software company would post earnings of $0.41 per share when it actually produced earnings of $0.47, delivering a surprise of +14.63%.

Over the last four quarters, the company has surpassed consensus EPS estimates four times.

Tenable, which belongs to the Zacks Internet - Software industry, posted revenues of $268.51 million for the quarter ended June 2026, surpassing the Zacks Consensus Estimate by 1.26%. This compares to year-ago revenues of $247.29 million. The company has topped consensus revenue estimates four times over the last four quarters.

The sustainability of the stock's immediate price movement based on the recently-released numbers and future earnings expectations will mostly depend on management's commentary on the earnings call.

Tenable shares have added about 33.3% since the beginning of the year versus the S&P 500's gain of 8.5%.

What's Next for Tenable?While Tenable has outperformed the market so far this year, the question that comes to investors' minds is: what's next for the stock?

There are no easy answers to this key question, but one reliable measure that can help investors address this is the company's earnings outlook. Not only does this include current consensus earnings expectations for the coming quarter(s), but also how these expectations have changed lately.

Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions. Investors can track such revisions by themselves or rely on a tried-and-tested rating tool like the Zacks Rank, which has an impressive track record of harnessing the power of earnings estimate revisions.

Ahead of this earnings release, the estimate revisions trend for Tenable was mixed. While the magnitude and direction of estimate revisions could change following the company's just-released earnings report, the current status translates into a Zacks Rank #3 (Hold) for the stock. So, the shares are expected to perform in line with the market in the near future. You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.

It will be interesting to see how estimates for the coming quarters and the current fiscal year change in the days ahead. The current consensus EPS estimate is $0.50 on $270.45 million in revenues for the coming quarter and $1.95 on $1.08 billion in revenues for the current fiscal year.

Investors should be mindful of the fact that the outlook for the industry can have a material impact on the performance of the stock as well. In terms of the Zacks Industry Rank, Internet - Software is currently in the bottom 41% of the 250 plus Zacks industries. Our research shows that the top 50% of the Zacks-ranked industries outperform the bottom 50% by a factor of more than 2 to 1.

Another stock from the same industry, Exodus Movement, Inc. (EXOD - Free Report) , has yet to report results for the quarter ended June 2026. The results are expected to be released on August 10.

This company is expected to post quarterly loss of $0.14 per share in its upcoming report, which represents a year-over-year change of -112.5%. The consensus EPS estimate for the quarter has remained unchanged over the last 30 days.

Exodus Movement, Inc.'s revenues are expected to be $19.2 million, down 25.7% from the year-ago quarter.

Forward-Looking Statements

This press release includes forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. All statements contained in this press release other than statements of historical fact, including statements regarding our future results of operations and financial position, the ability of our partnerships with Anthropic and OpenAI to help drive new research, strengthen the security and capabilities of Tenable and help customers understand how frontier AI models behave, our ability to help transform threat investigations into precise remediation action, our business strategy, market opportunity and plans and objectives for future operations, are forward-looking statements and represent our views as of the date of this press release. The words “anticipate,” "believe,” “continue,” “estimate,” “expect,” “intend,” “may,” “will” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of assumptions and risks and uncertainties, many of which involve factors or circumstances that are beyond our control that could affect our financial results. These risks and uncertainties are detailed in the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2025 and other filings that we make from time to time with the SEC, which are available on the SEC's website at sec.gov. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this press release may not occur and actual results could differ materially and adversely from those anticipated or implied in any forward-looking statements. Except as required by law, we are under no obligation to update these forward-looking statements subsequent to the date of this press release, or to update the reasons if actual results differ materially from those anticipated in the forward-looking statements.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use certain non-GAAP financial measures, as described below, to understand and evaluate our core operating performance. These non-GAAP financial measures, which may be different than similarly titled measures used by other companies, are presented to enhance the overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We believe that these non-GAAP financial measures provide useful information about our financial performance, enhance the overall understanding of our past performance and future prospects and are helpful to investors in comparing our financial results over multiple periods with other companies in our industry.

Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the financial tables accompanying this press release.

Free Cash Flow and Unlevered Free Cash Flow: We define free cash flow, a non-GAAP financial measure, as net cash provided by operating activities less purchases of property and equipment and capitalized software development costs. We believe free cash flow is an important liquidity measure of the cash that is available (if any), after purchases of property and equipment and capitalized software development costs, for investment in our business and to make acquisitions. We believe that free cash flow is useful as a liquidity measure because it measures our ability to generate cash. We define unlevered free cash flow as free cash flow plus cash paid for interest and other financing costs. We believe unlevered free cash flow is useful as a liquidity measure as it measures the cash that is available to invest in our business and meet our current debt obligations and future financing needs. However, given our debt obligations, non-cancelable commitments and other contractual obligations, unlevered free cash flow does not represent residual cash flow available for discretionary expenses.

Non-GAAP Income from Operations and Non-GAAP Operating Margin: We define these non-GAAP financial measures as their respective GAAP measures, excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses, costs related to the intra-entity asset transfers resulting from the internal restructuring of legal entities, and amortization of acquired intangible assets. Acquisition-related expenses include transaction and integration expenses, as well as costs related to the intercompany transfer of acquired intellectual property. Restructuring expenses include non-ordinary course severance, employee related benefits, and other charges to reorganize business operations. We believe that the exclusion of these expenses provides for a useful comparison of our operating results to prior periods and to our peer companies, which commonly exclude restructuring expenses.

Non-GAAP Net Income and Non-GAAP Earnings Per Share: We define non-GAAP net income as GAAP net income (loss), excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses and amortization of acquired intangible assets, including the applicable tax impacts. In addition, we exclude the tax impact and related costs of intra-entity asset transfers resulting from the internal restructuring of legal entities as well as deferred income tax benefits recognized in connection with acquisitions. We use non-GAAP net income to calculate non-GAAP earnings per share.

Non-GAAP Gross Profit and Non-GAAP Gross Margin: We define non-GAAP gross profit as GAAP gross profit, excluding the effect of stock-based compensation and amortization of acquired intangible assets. Non-GAAP gross margin is defined as non-GAAP gross profit as a percentage of revenue.

Non-GAAP Sales and Marketing Expense, Non-GAAP Research and Development Expense and Non-GAAP General and Administrative Expense: We define these non-GAAP measures as their respective GAAP measures, excluding stock-based compensation, acquisition-related expenses and costs related to intra-entity asset transfers resulting from the internal restructuring of legal entities.

Key Takeaways Tenable is using Hexa AI to automate risk triage and remediation across exposure management workflows. TENB is expanding Tenable One with cloud, identity, OT security and 300 pre-built integrations.TENB partners with OpenAI and Anthropic while proving AI advantages can drive sustained growth. Tenable Holdings (TENB - Free Report) sits near the center of a cybersecurity shift shaped by artificial intelligence. As AI accelerates vulnerability discovery and shortens the time between exposure and exploit, enterprises need faster ways to identify, prioritize and remediate risk.

That backdrop supports demand for unified exposure management. TENB’s challenge is turning that trend into durable product differentiation, sustained execution and better stock performance.

Tenable Benefits From a Faster Threat CycleAI is changing the pace of cyber defense. Frontier models are making vulnerability discovery faster, increasing pressure on security teams that already manage sprawling IT, cloud, identity and operational technology environments.

That urgency supports platforms that unify visibility, context and action. Narrow point products may still solve specific problems, but exposure management becomes more valuable when buyers need to understand which risks matter most and how quickly they can be fixed.

The competitive field is broad. Qualys (QLYS - Free Report) and Rapid7 (RPD - Free Report) remain relevant vulnerability management peers, while CrowdStrike, Palo Alto Networks (PANW - Free Report) and Wiz compete from adjacent areas such as endpoint and cloud security. That peer set underscores why TENB must keep expanding beyond traditional vulnerability scanning.

TENB Uses Hexa AI to Deepen Platform ValueTenable’s AI strategy centers on automation. Hexa AI is positioned as an agentic orchestration engine designed to automate triage and remediation workflows, helping turn exposure intelligence into action at machine speed.

That matters because buyers are not just looking for more alerts. They need systems that can prioritize risks and accelerate response. Hexa AI’s tiered packaging is also expected to support higher average selling prices over time.

Flex pricing adds another adoption lever. By simplifying per-asset procurement, Flex pricing may reduce friction as customers expand their exposure management footprint.

Qualys and Rapid7 are natural comparison points because security buyers often evaluate vulnerability management platforms against each other. TENB’s task is to show that Hexa AI and Tenable One create a broader operating model rather than simply adding another AI feature.

Tenable Pushes Into Cloud, Identity and OTPlatform convergence is central to the TENB story. Tenable One combines vulnerability management with cloud security, identity exposure, operational technology security, web app scanning and attack surface management.

That breadth gives TENB a wider role across modern attack surfaces. The company has also added native operational technology discovery capabilities, extending visibility into cyber-physical systems without additional hardware.

Recent milestones strengthen that platform narrative. Tenable’s cloud security platform achieved FedRAMP High and Impact Level 5 authorization, improving its ability to support U.S. federal agencies. The company also announced AI-powered cloud detection and response capabilities and more than 300 pre-built integrations through the Tenable One Open Connector.

CrowdStrike, Palo Alto Networks and Wiz highlight the pressure from larger and cloud-focused security platforms. Their presence makes TENB’s push into cloud, identity and operational technology more necessary as customers consolidate security spending.

TENB Must Keep Its AI Edge From NarrowingThe same AI trend expanding demand also raises competitive risk. If AI lowers the cost and complexity of building vulnerability discovery and prioritization tools, adjacent vendors could move deeper into exposure management.

That risk is not abstract. Qualys, Rapid7, CrowdStrike, Palo Alto Networks and Wiz are all capable of narrowing TENB's AI edge if they close the gap on automation and prioritization.

Partnerships with OpenAI and Anthropic help TENB stay close to frontier model development. Tenable has participated in OpenAI’s Trusted Access for Cyber program and has worked with Anthropic to integrate Claude-powered workflows into Hexa AI.

Those relationships are useful, but they are not enough on their own. Because they are non-exclusive, TENB still has to convert early access into durable product advantages that are hard for peers to replicate.

Tenable’s Ratings Reflect Trend Strength, Stock RiskThe bottom line is that TENB is tied to a powerful cybersecurity trend, but the stock still carries execution risk. AI-driven vulnerability discovery may continue to lift demand for exposure management, yet TENB must prove that platform breadth, automation and partner access can translate into sustained growth.

The Zacks Consensus Estimate for TENB’s 2026 earnings is pegged at $1.95 per share, unchanged over the past 30 days and indicating 22.64% year-over-year growth.

TENB currently carries a Zacks Rank #4 (Sell). That rank points to a weak short-term earnings estimate revision setup, even though the company has favorable Style Scores.

You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

The stock has a Growth Score of A, Momentum Score of A and VGM Score of A. These scores suggest favorable growth and momentum characteristics, but Style Scores are best used with the Zacks Rank. For now, the trend is promising, while the stock still needs clearer proof of sustained execution and improved estimate momentum.

COLUMBIA, Md., July 15, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced the expansion of the Tenable One Exposure Management Platform, unifying application security risks with all other exposure data. By integrating static code vulnerability data, Tenable One delivers complete, code-to-runtime visibility across the entire attack surface.

Security teams have long struggled with a code security problem where vulnerable code reaches production faster than it can be reviewed. This problem is exacerbated by the use of generative AI, which empowers developers to ship code three to four times faster, while potentially introducing flaws at 10x the rate.1 Application security teams and developers typically rely on siloed solutions that lack the contextual infrastructure intelligence required to determine if a code vulnerability poses a real-world threat to the business. This disconnected approach creates a major and exploitable blind spot.

Tenable One ingests, analyzes and normalizes data from relevant application development and security sources, including AI application security tools, such as Claude Security. Tenable One then connects all ingested exposure data – unifying Tenable telemetry with data from other security tools, including endpoint protection, cloud security, vulnerability management, operational technology security and more, and vital business context from repositories like configuration management databases – designed to deliver the most complete view of enterprise risk, and accelerate remediation prioritization and action. With this platform expansion, Tenable One shifts organizations from reactive application scanning to proactive risk prioritization, connecting code risks to the runtime systems, cloud workloads, identities and attack paths they put at risk.

“Bringing application security data into Tenable One, we're giving our customers the context they’ve been missing,” said Eric Doerr, Chief Product Officer, Tenable. “Security teams don’t need to wade through a sea of vulnerabilities. With Tenable One, security teams know exactly where they are exposed the moment an exposure is created – whether an agentic AI security tool discovers a new zero-day in an open-source library or a human error introduces risk. For the first time, security teams can see code flaws and prioritize remediation actions alongside all other forms of risk for more effective risk reduction.”

Application security data integrations are now available for all Tenable One customers. More information about Tenable One and application security data integrations is available at: https://www.tenable.com/blog/application-security-data-exposure-management-integration

Shares of Tenable Holdings (TENB +6.97%) rallied on Monday, up 6.7% on the day, and extending a massive 100%-plus run since the stock's bottom back in April.

Tenable was initially caught up in the software "SaaS-pocalypse" this year following the release of Anthropic's Claude code and its associated capabilities in coding and cybersecurity. Still, it appears the fears over cybersecurity leaders may be overdone, as these companies appear to be deploying leading LLMs within their trusted software architecture, rather than being disrupted by them.

The cybersecurity cohort got another boost today from a Wall Street analyst, who upgraded a group of names in the sector, with Tenable seeing its price target nearly double.

Scotiabank upgrades On Monday, sell-side analysts Patrick Colville and Joe Vandrick of Scotiabank published a note in which the analysts upgraded a slew of cybersecurity stocks, Tenable among them. The analysts' theory is that the latest artificial intelligence models are so powerful that they will increase cyber threats throughout this year and 2027, forcing companies to increase their cybersecurity budgets.

While information technology research firm Gartner (IT 0.85%) predicts 14.5% growth in cybersecurity spending this year, Colville and Vandrick believe that estimate is conservative. As a result, the analysts increased their price targets on the group of stocks, including Tenable's, nearly doubling it from $26 to $50.

Tenable is a known leader across multiple "surfaces" of modern enterprise IT departments. In fact, Gartner named it "the company to beat" for AI-powered vulnerability assessment just last week. So, Tenable stands to benefit from new and emerging threats across multiple "attack surfaces."

Tenable could be a strong comeback story Despite the recent doubling, Tenable stock still trades well below its all-time highs set in April 2022. Currently, its market cap is just $4.5 billion, with just a 20 forward P/E ratio based on adjusted (non-GAAP) earnings estimates for 2026.

That's still not expensive for a profitable software company growing around 10%, and which could be due for some reacceleration, if Gartner's forecast is correct. Like many of its peers, Tenable faces some disruption risk from generative AI; however, if the company can adapt and harness AI for future growth, shares look very cheap, even after today's bounce.

COLUMBIA, Md., July 01, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced that Gartner has identified Tenable as the company to beat for AI-powered exposure assessment in its report, AI Vendor Race: Tenable Is the Company to Beat for AI-Powered Exposure Assessment.

According to Gartner, "Tenable's long-standing dominance in vulnerability assessment, its strong asset and attack surface discovery capabilities, and its ability to execute on its AI strategy make it the front-runner in AI-powered exposure assessment."

The Gartner report further notes that, “Tenable’s broad attack surface coverage sets it apart from competitors. Tenable One is a well-integrated platform that spans traditional IT, identity, cloud, CPS and container environments.” Gartner adds that, “This visibility extends to emerging attack surfaces such as AI. Tenable identifies shadow AI usage and can also prioritize AI exposures like sensitive data leakage, misconfigurations, novel AI attacks, risky agent behavior, and unsafe integrations with external tools.”

“Cybersecurity is entering a new era where AI is changing both how organizations operate and how attackers exploit them," said Mark Thurmond, co-CEO, Tenable. "Organizations need a modern approach that not only gives them complete visibility across their expanding attack surface, but helps them act on risk faster. We believe Gartner's recognition reflects our continued commitment to enabling customers to keep pace with that change.”

We feel the Gartner recognition builds on a series of recent AI milestones for Tenable. In recent months, the company announced the general availability of Tenable Hexa AI, the agentic AI engine inside the Tenable One Exposure Management Platform, expanded its Tenable One AI Exposure capabilities to help customers protect their AI attack surface, and joined a select group of cybersecurity companies participating in both Anthropic's Project Glasswing initiative and OpenAI's Daybreak Cyber Partner Program. Together, these investments are helping shape the next generation of AI-powered cybersecurity while enabling customers to move beyond identifying exposures to continuously prioritizing and reducing cyber risk.

“We're still in the early innings of AI in cybersecurity,” said Steve Vintz, co-CEO, Tenable. “The next phase isn't just identifying exposures – it's enabling security teams to continuously understand, prioritize and remediate them with AI working alongside people. That's where we're investing, and where we believe the market is headed.”

Companies will explore how frontier AI can help organizations identify, prioritize and reduce cyber risk faster in the AI era June 22, 2026 13:08 ET  | Source: Tenable Holdings, Inc.

COLUMBIA, Md., June 22, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced it is working with OpenAI as part of the OpenAI Daybreak Cyber Partner Program. The collaboration brings together OpenAI's frontier AI capabilities, including GPT-5.5, and Tenable's leadership in exposure management to help organizations better understand cyber risk, prioritize action and stay ahead of attackers through Tenable product and service workflows.

The announcement comes as AI is reshaping the threat landscape. Attackers are already using AI to accelerate reconnaissance, automate vulnerability discovery and compress the window between exposure and exploitation. Security teams face a growing asymmetry: the volume and complexity of potential exposures is expanding faster than any team can manually assess, while the time available to act continues to shrink.

The Tenable One Exposure Management Platform was built for exactly this challenge. Rather than generating more findings, Tenable One helps organizations understand which exposures actually matter. Powered by the Tenable Exposure Data Fabric, the platform connects exposure intelligence from across the modern attack surface and applies the context needed to distinguish what is merely vulnerable from what is truly risky. Combined with frontier AI capabilities, this rich foundation helps organizations move from analysis to action faster, enabling security teams to focus on the exposures most likely to impact the business before attackers can capitalize on them.

The collaboration is expected to focus on several areas, including:

Advancing cybersecurity research and exposure intelligenceAccelerating the identification and prioritization of exploitable exposures and attack pathsImproving how security teams prioritize, validate and respond to the exposures that matter mostStreamlining security operations and accelerating risk reduction “The AI era requires a fundamentally new approach to cybersecurity,” said Eric Doerr, Chief Product Officer, Tenable. “Attackers are moving faster and operating at a scale that makes purely reactive security untenable. As part of OpenAI’s Trusted Access for Cyber program, Tenable is evaluating how GPT-5.5 can help accelerate defensive workflows through secure product integrations, enabling customers to stay ahead of attackers and move faster with confidence. This is what proactive security looks like in practice.”

The announcement underscores Tenable's continued investment in AI-powered exposure management and its commitment to helping customers proactively reduce cyber risk in an increasingly complex threat landscape.
