The section titled "Non-GAAP Financial Measures" below describes our usage of non-GAAP financial measures. Reconciliations between historical GAAP and non-GAAP information are contained at the end of this press release following the accompanying financial data.

Business Highlights

For the full year 2021, we processed 92.2 trillion impressions, an increase of 96% over 2020. Since the first quarter of 2020, cost of revenue per million impressions processed declined by nearly 50%;
Revenue from fast-growing advertising formats mobile and omnichannel video, which includes CTV,³ grew 41% year-over-year and represented 67% of total revenue in the fourth quarter;
Revenue from CTV² in the fourth quarter of 2021 grew by more than six times over the fourth quarter of 2020. As of the end 2021, we programmatically monetized CTV inventory from 167 publishers, up from 154 publishers in the third quarter of 2021;
We are well diversified across more than 20 verticals and primarily associated with brand advertising spend. In the fourth quarter of 2021, the top 10 ad verticals in aggregate grew over 50% year over year;
Supply path optimization represented over 25% of total activity in the fourth quarter, up from approximately 10% at the beginning of 2020;
Drove expanded use of our platform through adoption of our robust portfolio of omnichannel addressability solutions, including first-party data, known identity and contextual targeting;
Global headcount increased by 30% in 2021, with the majority of new hires in technology and go-to-market teams. We plan to double our engineering team over the next 12-18 months, funded by sustainable profits and cash flows; and
Expanded our global footprint last year into South Korea and opened offices in Madrid, Paris and Shanghai.

"2021 was an outstanding year for PubMatic. We outpaced the growth of the overall market, delivered record profits and cash flow, and significantly invested for continued long-term growth," said Steve Pantelick, CFO at PubMatic. "Over the last two years, we doubled our revenue and scaled the business very profitably. Our business is emerging with structurally higher levels of profitability than prior to the pandemic, with an anticipated annual adjusted EBITDA margin of 35% plus for fiscal year 2022. With the strength and durability of our model, coupled with numerous growth opportunities from existing and new products, we are confident in our 25% profitable revenue growth target for 2022."

Financial Outlook

Our guidance assumes that the global economy continues to recover and we do not have any major COVID-19-related setbacks that may cause economic conditions to deteriorate or otherwise significantly reduce advertiser demand. Accordingly, we estimate the following:

For the first quarter of 2022, we expect revenue to be in the range of $53 million to $55 million, or 25% year over year growth at the mid-point. We expect adjusted EBITDA to be in the range of $14 million to $16 million, representing approximately a 27% to 29% margin.
For fiscal year 2022, we expect revenue to be in the range of $282 million to $286 million, representing 25% year over year growth at the mid-point. We expect adjusted EBITDA to be in the range of $101 million to $106 million, or 36% to 37% margin.

Although we provide guidance for adjusted EBITDA, 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 Monday, February 28, 2022 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 https://investors.pubmatic.com. 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, we believe that adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income and non-GAAP diluted EPS, each a non-GAAP measure, are useful in evaluating our operating performance. We define adjusted EBITDA as net income adjusted for stock-based compensation expense, depreciation and amortization, unrealized gains on equity investments, impairments of long-lived assets, interest income, and provision for income taxes. Adjusted EBITDA margin represents adjusted EBITDA calculated as a percentage of revenue. We define non-GAAP net income as net income adjusted for stock-based compensation expense, unrealized gains/losses on equity investments and the income tax impact on those adjustments. In order to calculate non-GAAP diluted EPS, we use a non-GAAP weighted-average share count. We define non-GAAP weighted-average shares, diluted, as GAAP weighted average shares used to compute net income per share attributable to common stockholders adjusted to reflect the common stock issued in connection with our initial public offering that are outstanding as of the end of the period as if they were outstanding as of the beginning of the period for comparability.

In addition to operating income and net income, we use adjusted EBITDA and non-GAAP net Income 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, provision for income taxes, and certain one-time items such as impairments of long-lived assets, that can vary substantially from company to company depending upon their financing, capital structures and the method by which assets were acquired;
Our management uses adjusted EBITDA and non-GAAP net income in conjunction with GAAP financial measures for planning purposes, including the preparation of our annual operating budget, as a measure of operating performance 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 these non-GAAP financial measures have limitations as analytical tools, 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 and;
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;
Non-GAAP net income does not include: (a) unrealized gains/losses result from our equity investments; (b) the potentially dilutive impact of stock-based compensation; or (c) income tax effects for stock-based compensation and unrealized gains/losses from our equity investments.

Because of these and other limitations, you should consider adjusted EBITDA and non-GAAP net income along with other GAAP-based financial performance measures, including net income 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 first quarter of 2022 and the full year 2022. 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; 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 ongoing COVID-19 pandemic, including the resulting global economic uncertainty; limitations imposed on our collection, use or disclosure of data about advertisements; 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.

^{____________________}

¹ Fourth quarter 2021 and fiscal year 2021 GAAP net income includes an unrealized gain on equity investments. Net of income taxes, the impact was $4.2 million.

² Net dollar-based retention is calculated by starting with the revenue from publishers in the trailing twelve months ended December 31, 2020 ("Prior Period Revenue"). We then calculate the revenue from these same publishers in the trailing twelve months ended December 31, 2021 ("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.
