“We delivered another quarter of outstanding results, with accelerated revenue growth of 20%, highlighting our strong customer relationships, our breadth of solutions and growth across all formats and channels,” said Rajeev Goel, co-founder and CEO at PubMatic. “The digital supply chain of the future we are building brings new opportunities that are best addressed on the sell-side of the ecosystem, which sits closest to the consumer. These opportunities, including the need for increased innovation and efficiency, changing privacy regulations, and an onslaught of new ad inventory from CTV and commerce media, require deep and specialized technology.

We've spent 17 years building differentiated solutions and we believe our competitive moat is widening while our logo list continues to grow.”

Scaled access to premium inventory, audiences and data attracts increased buyer demand

• PubMatic’s strength in SPO, private marketplace and programmatic guaranteed fueled new partnerships with marquee CTV streamers including DISH Media, Vevo and Virgin Media UK.
• Expanded into a new category of content creators and partnered with immersive platform Roblox to enable programmatic media buying of Roblox’s video advertising inventory. The partnership will allow more brands to seamlessly reach Roblox’s global community while enabling Roblox to gain scaled access to premium brand advertising demand.
• Recently announced a first-of-its-kind solution with GroupM in which together we are delivering AI generated cohort-based audience segments customized for each advertiser client.

“Continuing our momentum from Q4, in the first quarter, we accelerated revenue growth, while delivering strong margins and free cash flow. Excluding revenue from Yahoo’s owned and operated inventory, revenue grew an impressive 25% over last year. Monetized impressions continued to grow across all formats and channels as the need from publishers and ad buyers for our differentiated sell-side technology increases,” said Steve Pantelick, CFO at PubMatic. “We are making steady progress on our 2024 key operating priorities which include increasing investment for revenue growth acceleration, delivering cost efficiencies, and generating strong free cash flow. As a result, we are raising our full year guidance. At the midpoints, we expect year-over-year revenue growth to be 12%, and adjusted EBITDA margin to be approximately 31%.”

Financial Outlook

Our Q2 and full year outlook reflects a balance between our growth trajectory and an anticipated headwind as one of our top DSPs plans to revise its bidding approach. We anticipate offsetting this headwind as the year progresses with continued strong underlying growth across ad formats, channels, and regions, as well as emerging revenue streams. Further, our outlook assumes that general market conditions do not significantly deteriorate as it relates to current macroeconomic and geopolitical conditions.

Accordingly, we estimate the following:

For the second quarter of 2024, we expect the following:

• Revenue to be between $69 million to $71 million.
• Adjusted EBITDA to be in the range of $17 million to $19 million, representing approximately a 26% margin at the midpoint.

For the full year 2024, we are raising revenue and adjusted EBITDA guidance and expect the following:

• Year-over-year revenue to be between $296 million and $304 million, representing approximately 12% growth at the midpoint.
• Adjusted EBITDA to be in the range of $90 million to $94 million, representing approximately 31% margin at the midpoint.
• Free cash flow to be in line with 2023
• CapEx to be in the range of $16 million – $18 million

Although we provide guidance for adjusted EBITDA and free cash flow, we are not able to provide guidance for net income, the most directly comparable GAAP measure. Certain elements of the composition of GAAP net income, including stock-based compensation expenses, are not predictable, making it impractical for us to provide guidance on net income or to reconcile our adjusted EBITDA guidance to net income without unreasonable efforts. For the same reason, we are unable to address the probable significance of the unavailable information.

Conference Call and Webcast details

PubMatic will host a conference call to discuss its financial results on Tuesday, May 7, 2024 at 2:00 p.m. Pacific Time (5:00 p.m. Eastern Time). A live webcast of the call can be accessed from PubMatic’s Investor Relations website at An archived version of the webcast will be available from the same website after the call.

Non-GAAP Financial Measures

In addition to our results determined in accordance with U.S. generally accepted accounting principles (GAAP), including, in particular operating income, net cash provided by operating activities, and net income (loss), we believe that adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, non-GAAP net income per diluted share and free cash flow, each a non-GAAP measure, are useful in evaluating our operating performance. We define adjusted EBITDA as net income (loss) adjusted for stock-based compensation expense, depreciation and amortization, unrealized gain, loss or impairment of equity investment, interest income, acquisition-related and other expenses, and provision for (benefit from) income taxes. Adjusted EBITDA margin represents adjusted EBITDA calculated as a percentage of revenue. We define non-GAAP net income as net income (loss) adjusted for unrealized (gain) loss on equity investments, stock-based compensation expense, acquisition-related and other expenses, and adjustments for income taxes. We define non-GAAP free cash flow as net cash provided by operating activities reduced by purchases of property and equipment and capitalized software development costs.

In addition to operating income and net income, we use adjusted EBITDA, non-GAAP net income, and free cash flow as measures of operational efficiency. We believe that these non-GAAP financial measures are useful to investors for period to period comparisons of our business and in understanding and evaluating our operating results for the following reasons:

• Adjusted EBITDA and non-GAAP net income are widely used by investors and securities analysts to measure a company’s operating performance without regard to items such as stock-based compensation expense, depreciation and amortization, interest expense, and provision for (benefit from) income taxes that can vary substantially from company to company depending upon their financing, capital structures and the method by which assets were acquired; and,
• Our management uses adjusted EBITDA, non-GAAP net income, and free cash flow in conjunction with GAAP financial measures for planning purposes, including the preparation of our annual operating budget, as a measure of operating performance [or, in the case of free cash flow, as a measure of liquidity], and the effectiveness of our business strategies and in communications with our board of directors concerning our financial performance; and adjusted EBITDA provides consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations, and also facilitates comparisons with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results.

Our use of non-GAAP financial measures has limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are as follows:

• Adjusted EBITDA does not reflect: (a) changes in, or cash requirements for, our working capital needs; (b) the potentially dilutive impact of stock-based compensation; or (c) tax payments that may represent a reduction in cash available to us;
• Although depreciation and amortization expense are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; and
• Non-GAAP net income does not include: (a) unrealized gains/losses resulting from our equity investment; (b) the potentially dilutive impact of stock-based compensation; (c) income tax effects for stock-based compensation and unrealized gains/losses from our equity investment; or (d) acquisition-related and other expenses.
  
  

Because of these and other limitations, you should consider adjusted EBITDA, non-GAAP net income, and free cash flow along with other GAAP-based financial measures, including net income (loss) and cash flow from operating activities, and our GAAP financial results.

Forward Looking Statements

This press release contains “forward-looking statements” regarding our future business expectations, including our guidance relating to our revenue and adjusted EBITDA for the second quarter of 2024 and revenue, adjusted EBITDA margin, free cash flow and capital expenditures for full year 2024, our expectations regarding our total addressable market, future market growth, and our ability to gain market share. These forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions and may differ materially from actual results due to a variety of factors including: our dependency on the overall demand for advertising and the channels we rely on; our existing customers not expanding their usage of our platform, or our failure to attract new publishers and buyers; our ability to maintain and expand access to spend from buyers and valuable ad impressions from publishers; the rejection of the use of digital advertising by consumers through opt-in, opt-out or ad-blocking technologies or other means; our failure to innovate and develop new solutions that are adopted by publishers; the war between Ukraine and Russia and the ongoing conflict between Israel and Palestine, and the related measures taken in response by the global community; the impacts of inflation as well as fiscal tightening and rising interest rates; public health crises, including the resulting global economic uncertainty; limitations imposed on our collection, use or disclosure of data about advertisements; the lack of similar or better alternatives to the use of third-party cookies, mobile device IDs or other tracking technologies if such uses are restricted; any failure to scale our platform infrastructure to support anticipated growth and transaction volume; liabilities or fines due to publishers, buyers, and data providers not obtaining consents from consumers for us to process their personal data; any failure to comply with laws and regulations related to data privacy, data protection, information security, and consumer protection; and our ability to manage our growth. Moreover, we operate in a competitive and rapidly changing market, and new risks may emerge from time to time.

⁽¹⁾Stock-based compensation expense includes the following:

Reported GAAP diluted loss per share for the three months ended March 31, 2024 and 2023 were calculated using basic share count. Non-GAAP diluted earnings per share for the three months ended March 31, 2024 was calculated using diluted share count which includes approximately 5 million shares of dilutive securities related to employee stock awards.

¹ Net dollar-based retention is calculated by starting with the revenue from publishers in the trailing twelve months ended March 31, 2023 (Prior Period Revenue). We then calculate the revenue from these same publishers in the trailing twelve months ended March 31, 2024 (Current Period Revenue). Current Period Revenue includes any upsells and is net of contraction or attrition, but excludes revenue from new publishers. Our net dollar-based retention rate equals the Current Period Revenue divided by Prior Period Revenue. Net dollar-based retention rate is an important indicator of publisher satisfaction and usage of our platform, as well as potential revenue for future periods

² Omnichannel video spans across desktop, mobile and CTV devices.

³ Beginning in the third quarter of fiscal 2023, we no longer exclude the impact of post-acquisition cash compensation agreements for certain key acquired employees from the Martin acquisition from Adjusted EBITDA and Non-GAAP net income. Prior period amounts for Adjusted EBITDA and Non-GAAP net income have been updated to conform to the current period presentation. For comparative purposes, the impact of this change to our adjusted EBITDA and Non-GAAP net income (loss) for the three months ended March 31, 2023 is a decrease to Adjusted EBITDA income and Non-GAAP net income of $1.0 million.
