"Forrester's report has confirmed what our customers experience every day: we are the data backbone that modern GTM runs on," said Henry Schuck, CEO and Founder of ZoomInfo.

ZoomInfo received:

Industry Recognition: ZoomInfo

ZoomInfo's ABM is Built for Outcomes

ZoomInfo Recognized as a Leader in the 2025 Gartner® Magic Quadrant™ for Account-Based Marketing Platforms, the second consecutive year(1)(2)

Gartner evaluates vendors on Ability to Execute and Completeness of Vision. In our view, our placement in these categories reflects the momentum we've seen firsthand: more customers adopting signal-based workflows, more cross-functional teams using ZoomInfo Sales, Marketing, and Copilot to drive pipeline from day one, and more GTM operators betting big on data quality as the foundation for scalable growth.

Recognition from Gartner is powerful, and what makes this year stand out is that we're also the only vendor recognized as a Customers' Choice for ABM, as seen in the 2025 Gartner® Voice of the Customer Report(3)(4) for Account-Based Marketing Platforms from Gartner Peer Insights™.

That matters. We think analyst recognition tells one part of the story. But when customers say we're getting it right in product quality, roadmap strength, and real-world results, that's what really moves the needle.

We believe this dual recognition shows we're solving for both sides of the table: the analysts tracking market direction, and the operators pushing for real outcomes.

Unifying Sales and Marketing Intelligence with ZoomInfo

About the Company

Nerdio is an IT software platform that simplifies and automates the deployment, management, and cost-optimization of native Microsoft cloud technologies, particularly Azure Virtual Desktop (AVD) and Windows

365. It is designed to make complex Microsoft cloud environments easy to build and manage.

The Challenge

Nerdio helps IT departments and managed service providers get the most out of their Microsoft cloud investments. The company applies that same commitment to innovation internally, in the way it runs its own go-to-market (GTM) engine. For Amber Thompson, Marketing Operations Director, that means asking a harder question than most teams are willing to ask: not just how do we generate more pipeline, but how do we ensure every person on our go-to-market team has exactly what they need, exactly when they need it.

Until recently, the honest answer was: not well enough.

Nerdio was not lacking for data; however the data lives in silos, and the wrong people had access to the wrong pieces.

The Solution

"Our sellers and SDRs were spending a lot of time going back and forth in order to do account research," Thompson says. "The amount of context and information that they had at their fingertips to do that better was missing."

"Lightbulbs started to go off for me," she says. What she saw with GTM Studio was a way to pull conversation intelligence, intent signals, and data from across Nerdio's systems into a single unified table, and then deliver that context automatically to the people who needed it most, before they ever picked up the phone.

Using GTM Studio, Thompson's team built out account briefs that surface exactly what sellers need to know: relevant signals, suggested messaging, and key account context, all pre-assembled and ready to act on before the sprint begins.

"One of the mistakes we've always made as marketers is trying to force sellers to work exactly the way we think they should," Thompson says. "The idea is that we should be getting the data in the hands of the sellers wherever they're working. ZoomInfo follows them along the journey."

The Results

Two months into the deployment, the shift Thompson points to is less about a single metric and more about a fundamental change in how the team operates. Reps are spending less time on research and more time on outreach. Marketing and sales are collaborating earlier and more substantively. And the feedback loop between teams has tightened considerably.

"At Nerdio, we feel like we should be operating off of a central brain where all of our information is together and we are able to orchestrate plays based off of that information," she says. "And Zoominfo is a big part of that."

Looking ahead, Thompson's vision for Nerdio's GTM future is clear and ambitious: one centralized intelligence layer that orchestrates play across every team, powered by the full breadth of data the company has available.

Helping Syncro Build a Go-To-Market Engine From Scratch

About the Company

Syncro is a unified IT management platform that combines Remote Monitoring and Management (RMM) and Professional Services Automation (PSA) tools. Designed specifically for Managed Service Providers (MSPs) and internal IT departments, it consolidates endpoint management, ticketing, billing, and Microsoft 365 security into a single system with flat per-technician pricing.

The Challenge

Syncro is on a mission to unify IT and security operations into a single platform, giving MSPs and corporate IT teams the tools to secure and manage their environments without the budget of a large enterprise. Syncro has a focused product in a competitive market, and when Carl Koussan-Price joined as Chief Marketing Officer, he found a go-to-market operation (GTM) that was not keeping pace with the company's ambitions.

The entire motion was inbound. Google Ads were the primary growth lever. There were no outbound plays, no signal-based campaigns, and no data vendor. Worse, the marketing team couldn't even build a target audience on its own, every list required a trip to the operations team, a round of back-and-forth, and a CSV file passed between functions.

The Solution

Before Koussan-Price could launch a single outbound play, he had to solve a problem that had quietly stalled Syncro's growth for years: finding its own audience. Without a data partner, Syncro had no reliable way to identify and reach MSPs at scale.

Koussan-Price evaluated several platforms before committing to GTM Studio. With GTM Studio in place, the solution was immediately eliminating the internal bottlenecks that had slowed every previous campaign.

"The most junior people on my team - this [being] the first job they've ever had - are using GTM Studio effortlessly and frictionlessly," Koussan-Price says.

Three plays became the foundation of Syncro's new outbound engine. The first was the MSP identification campaign, finally possible at scale. The second was a closed-lost reengagement play, powered by Chorus integration, that pulled in conversation transcripts and summaries to personalize outreach. The third was a website visitor de-anonymization play using WebSiteID, targeting high-value pages like pricing, identifying the buying group, and routing them into outbound sequences automatically.

The Results

Within a couple of months of deploying GTM Studio, Syncro had launched more campaigns than the company had launched in the previous two years combined. The website visitor play alone has generated over $100k in ARR. The closed-lost play has contributed another $100k.

"We've been using GTM Studio for a couple of months now, and within that time, we've launched 35 campaigns through the platform, consisting of expansion and new business, and generated around $400k of pipeline and around $150k of revenue," Koussan-Price says.

"The days of burning out your team because you're launching too much doesn't necessarily need to exist when you can just build the campaign and let it start running itself and feeding itself with new data all the time. There's nothing really limiting us anymore."

1. Guidance as of August 5, 2026. We do not provide a quantitative reconciliation of the forward-looking non-GAAP financial measures included in this presentation to the most directly comparable GAAP measures due to the high variability and difficulty to predict certain items excluded from these non-GAAP financial measures; in particular, the effects of stock-based compensation expense, taxes and amounts under the exchange tax receivable agreement, deferred tax assets and deferred tax liabilities, and restructuring and transaction expenses. We expect the variability of these excluded items may have a significant, and potentially unpredictable, impact on

Tax Receivable Agreement

In connection with our IPO, we entered into two Tax Receivable Agreements ("TRA") with certain former unit holders of ZoomInfo Holdings LLC (the "TRA Holders"). The conversion of these pre-IPO units to common stock created a step-up in tax basis resulting in a deferred tax asset. The TRAs generally provide for payment by the Company to the TRA Holders of 85% of the net cash savings, if any, in U.S. federal and state income taxes that the Company realizes from the step-up. The Company retains a benefit of 15% from TRA savings.

The Company's deferred tax asset balance related to the step-up reflects 100% of the benefit of entering into the TRAs not yet realized. The TRA Liability represents 85% of the benefit, which is due to the TRA holders in a future period.

The TRA and its associated deferred tax assets are remeasured quarterly to reflect the impact of changes in the Company's blended state tax rate, U.S. federal and state tax legislation, and the Company's overall financial results. The remeasurement can have a material impact on the value of the TRA from period to period.

The TRA deductions are generally recognized as amortization over a 15-year period. To the extent the deductions result in the Company being in a taxable loss position, the corresponding TRA payment will be reduced, as the Company will not benefit from the deduction until the year in which the net operating loss is utilized. Therefore, the amount and timing of TRA payments can be substantially influenced by the Company's growth and profitability as well as legislative changes in any given year. Payments to TRA holders are incorporated in the "Tax receivable agreement payments" line in the "Financing activities" section of the Consolidated Statement of Cash Flows.

variability and difficulty to predict certain items excluded from these non-GAAP financial measures; in particular, the effects of stock-based compensation expense, taxes and amounts under the exchange 25

Non-GAAP Reconciliations

Q2 2026 EARNINGS CALL >NON-GAAP FINANCIAL MEASURES

Non-GAAP Financial Measures

To supplement our consolidated financial statements presented in accordance with GAAP, this presentation contains non-GAAP financial measures, including Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income, Adjusted Net Income Per Share, Unlevered Free Cash Flow, Unlevered Free Cash Flow Conversion, TTM Adjusted EBITDA and Cash EBITDA, Net Leverage Ratio, Adjusted Gross Margin, Adjusted Sales and Marketing Expense, Adjusted Research and Development Expense, and Adjusted General and Administrative Expense. We believe these non-GAAP measures are useful to investors in evaluating our operating performance because they eliminate certain items that affect period-over-period comparability and provide consistency with past financial performance and additional information about our underlying results and trends by excluding certain items that may not be indicative of our business, results of operations, or outlook.

Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for the comparable GAAP measures, but rather as supplemental information to our business results. This information should be read only in conjunction with our consolidated financial statements prepared in accordance with U.S. GAAP. There are limitations to these non-GAAP financial measures because they are not prepared in accordance with U.S. GAAP and may not be comparable to similarly titled measures of other companies due to potential differences in methods of calculation and items or events being adjusted. In addition, other companies may use different measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. A reconciliation is provided at the end of this presentation for each historical non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP. We do not provide a quantitative reconciliation of the forward-looking non-GAAP financial measures included in this presentation to the most directly comparable GAAP measures due to the high variability and difficulty to predict certain items excluded from these non-GAAP financial measures; in particular, the effects of stock-based compensation expense, taxes and amounts under the exchange tax receivable agreement, deferred tax assets and deferred tax liabilities, and restructuring and transaction expenses. We expect the variability of these excluded items may have a significant, and potentially unpredictable, impact on our future GAAP financial results.

We define Adjusted Operating Income as income (loss) from operations adjusted for, as applicable, (i) amortization of acquired technology and other acquired intangibles, (ii) goodwill impairment, (iii) equity-based compensation expense, (iv) restructuring and transaction-related expenses, (v) integration costs and acquisition-related expenses, and (vi) litigation settlement. We exclude the impact of amortization of acquired technology and other acquired intangibles, goodwill impairment, as well as equity-based compensation expense, because these are non-cash expenses and we believe that excluding these items provides meaningful supplemental information regarding performance and ongoing cash-generation potential. We exclude restructuring and transaction-related expenses, as well as integration costs and acquisition-related compensation, because such expenses are episodic in nature and have no direct correlation to the cost of operating our business on an ongoing basis. We have also excluded charges associated with litigation settlements related to class actions because we believe it represents an extraordinary litigation expense outside of our ordinary course of business and is not indicative of our operating performance. Adjusted Operating Income is presented because it is used by management to evaluate our financial performance and for planning and forecasting purposes. Additionally, we believe that it and similar measures are widely used by securities analysts and investors as a means of evaluating a company's operating performance. We define Adjusted Operating Income Margin as Adjusted Operating Income divided by revenue.

We define Adjusted Net Income as net income (loss) adjusted for, as applicable, (i) gain on debt extinguishment, (ii) amortization of acquired technology and other acquired intangibles, (iii) goodwill impairment, (iv) equity-based compensation expense, (v) restructuring and transaction-related expenses, (vi) integration costs and acquisition-related expenses, (vii) litigation settlement, (viii) TRA liability remeasurement (benefit) expense, (ix) other (income) loss, net and (x) tax impacts of adjustments to net income (loss). Adjusted Net Income is presented because it is used by management to evaluate our financial performance and for planning and forecasting purposes. Additionally, we believe that it and similar measures are widely used by securities analysts and investors as a means of evaluating a company's operating performance. Adjusted Net Income should not be considered as an alternative to cash flows from operating activities as a measure of liquidity or as an alternative to operating income (loss) or net income (loss) as indicators of operating performance. We define Adjusted Net Income Per Share as Adjusted Net Income divided by diluted weighted average shares outstanding used for Adjusted Net Income Per Share.

27

Q2 2026 EARNINGS CALL >NON-GAAP FINANCIAL MEASURES

Non-GAAP Financial Measures

We define Unlevered Free Cash Flow as net cash provided by operating activities less, as applicable, (i) purchases of property and equipment and other assets, plus (ii) cash interest expense, (iii) cash payments related to restructuring and transaction-related expenses, (iv) cash payments related to integration costs and acquisition-related compensation, and (v) litigation settlement payments. We define Unlevered Free Cash Flow Margin as Unlevered Free Cash Flow divided by revenue. Unlevered Free Cash Flow is presented because it is used by management to evaluate our financial performance and for planning and forecasting purposes. Additionally, we believe that it and similar measures are widely used by securities analysts and investors as a means of evaluating a company's operating performance. Unlevered Free Cash Flow should not be considered as an alternative to cash flows from operating activities as a measure of liquidity or as an alternative to operating income (loss) or net income (loss) as indicators of operating performance. Unlevered Free Cash Flow does not represent residual cash flow available for discretionary expenditures since, among other things, we have mandatory debt service requirements. We define Unlevered Free Cash Flow Conversion as Unlevered Free Cash Flow divided by Adjusted Operating Income.

We define Net Leverage Ratio to Adjusted EBITDA as total contractual maturity of outstanding indebtedness less cash, cash equivalents, and investments (as applicable), divided by trailing twelve months Adjusted EBITDA. EBITDA is defined as earnings before interest, taxes, depreciation, and amortization. Management further adjusts EBITDA to exclude certain items of a significant or unusual nature, including, as applicable, other (income) expense, net, gain on debt extinguishment, impact of certain non-cash items, such as goodwill impairment, equity-based compensation expense, restructuring and transaction-related expenses, integration costs and acquisition-related expenses, and litigation settlement. We exclude these items because these are either non-cash expenses which we do not consider indicative of performance and ongoing cash-generation potential or are episodic in nature and have no direct correlation to the cost of operating our business on an ongoing basis. Adjusted EBITDA is presented because it is used by management to evaluate our financial performance and for planning and forecasting purposes. Additionally, we believe that it and similar measures are widely used by securities analysts and investors as a means of evaluating a company's operating performance. Adjusted EBITDA should not be considered as an alternative to cash flows from operating activities as a measure of liquidity or as an alternative to operating income (loss) or net income (loss) as indicators of operating performance. We define Net Leverage Ratio to Cash EBITDA (defined as Consolidated EBITDA in our Credit Agreements) as total contractual maturity of outstanding indebtedness less cash, cash equivalents, and investments (as applicable), divided by trailing twelve months Cash EBITDA. Cash EBITDA is defined as Adjusted EBITDA adjusted for the unearned revenue adjustment, cash rent adjustment, and other lender adjustments. Net Leverage Ratio should not be considered as an alternative to other ratios of GAAP earnings to indebtedness.

We define Adjusted Gross Profit as gross profit plus (i) amortization of acquired technology, and as included within Cost of service, (ii) equity-based compensation expense, (iii) integration and deal related compensation, and

(iv) restructuring and transaction-related expenses. Adjusted Gross Margin is calculated as Adjusted Gross Profit divided by revenue.

We define Adjusted Sales and Marketing Expense as sales and marketing expense less, as included within sales and marketing expense, (i) integration and deal related compensation expense, (ii) equity-based compensation expense, and (iii) restructuring and transaction-related expenses. Adjusted Sales and Marketing as a percentage of Revenue is calculated as Adjusted Sales and Marketing divided by revenue.
