DoubleVerify Announces First Quarter 2021 Financial Results

Revenue Increased 32% Year-Over-Year to $67.6 Million Driven by Strong CTV and Social Volume Growth

Advertiser Programmatic Revenue Increased 42% to $33.9 Million

Net Income Increased to $5.6 Million; Adjusted EBITDA Increased 41% to $21.7 Million, or 32% of Revenue

NEW YORK – May 25, 2021 – DoubleVerify (“DV”) (NYSE: DV), a leading software platform for digital media measurement, data and analytics, today announced financial results for the first quarter ended March 31, 2021.

“Successfully completing our IPO was an important milestone for DoubleVerify, providing additional capital to further fuel our mission to create a stronger, safer and more secure digital ad ecosystem,” said Mark Zagorski, CEO of DoubleVerify. “We delivered record first quarter revenue, which grew 32% year-over-year, with Adjusted EBITDA exhibiting 41% growth. Our solid topline momentum was driven by global expansion via recent enterprise client wins, product success in fast growing sectors such as CTV, Social and Programmatic and the introduction of new solutions that leverage our ability to measure and verify across both the walled gardens and open internet without cookies or third-party tracking technologies. We are optimistic about continued strong growth for the remainder of 2021 and beyond.”

First Quarter 2021 Financial Highlights:

(All comparisons are to the first quarter of 2020)

	●	Total revenue of $67.6 million, an increase of 32%.
	●	Advertiser Direct revenue of $27.5 million, an increase of 24%.

Media Transactions Measured (“MTM”) for both CTV and Social increased by approximately 75%.

	●	Advertiser Programmatic revenue of $33.9 million, an increase of 42%.
	●	Supply-Side revenue of $6.1 million, an increase of 18%.
	●	Net income increased to $5.6 million, compared to $2.4 million.
	●	Adjusted EBITDA of $21.7 million, an increase of 41%.
	●	Diluted earnings per share increased to $0.04, compared to $0.02.

First Quarter 2021 Business Highlights:

	●	Grew revenue with recently won business at Unilever, UPS, UK Government (via Omnicom UK), Fujifilm Japan and Arnott’s Australia among numerous others.
	●	Expanded Custom Contextual targeting for programmatic advertisers, including activation on The Trade Desk.
	●	Expanded international coverage for CTV on Roku, building upon our existing measurement partnership, with plans for further international expansion.
	●	Continued to grow supply side business, with new customer wins including News Corp, Time, Inc. and Ziff Davis, among others.
	●	Enhanced the leadership team with the appointment of Julie Eddleman as EVP, Global Chief Commercial Officer (CCO), who will lead the Company’s sales and client service organizations worldwide, and Doug Campbell as Chief Strategy Officer, who will lead corporate strategy and M&A.
	●	Achieved additional Media Rating Council (MRC) accreditation in CTV for display and video rendered ad impression measurement and sophisticated invalid traffic (SIVT) filtration, including app fraud.
	●	Launched DV Authentic Attention™, the first privacy-friendly data solution to provide timely, impression-level insights to optimize campaign performance.
	●	Expanded Brand Safety/Suitability Services on Facebook video products, now offering the widest brand safety/suitability coverage of any provider on the platform.

“DoubleVerify continues to outpace the growth of the digital advertising market and is well positioned to deliver strong revenue growth and profitability in 2021,” said Nicola Allais, CFO of DoubleVerify. “In the first quarter, revenue growth was driven by continued success in launching new products and expanding market share in the programmatic, CTV and Social sectors. Additionally, we maintained strong customer retention in the quarter, evidenced by a gross revenue retention rate of over 95%. After the quarter closed, we received aggregate net proceeds of $282 million from the IPO and a concurrent private placement, further strengthening our balance sheet and bolstering our ability to expand our global footprint and accelerate our technology roadmap.”

Second Quarter and Full-Year 2021 Guidance:

DoubleVerify anticipates Revenue and Adjusted EBITDA to be in the following ranges:

Second quarter 2021:

	●	Revenue of $72 to $74 million, a year-over-year increase of 38% at the midpoint.
	●	Adjusted EBITDA in the range of $20 to $22 million, a year-over-year improvement of 34% at the midpoint.

Full year 2021:

	●	Revenue of $322 to $326 million, a year-over-year increase of 33% at the midpoint.
	●	Adjusted EBITDA in the range of $103 to $105 million, a year-over-year increase of 42% at the midpoint.

With respect to the Company’s expectations under "Second Quarter and Full Year 2021 Guidance" above, the Company has not reconciled the non-GAAP measure Adjusted EBITDA to the GAAP measure net income (loss) in this press release because the Company does not provide guidance for stock-based compensation expense, depreciation and amortization expense, acquisition-related costs, interest income, and income taxes on a consistent basis as the Company is unable to quantify these amounts without unreasonable efforts, which would be required to include a reconciliation of Adjusted EBITDA to GAAP net income (loss). In addition, the Company believes such a reconciliation would imply a degree of precision that could be confusing or misleading to investors.

Adjusted EBITDA

In addition to our results determined in accordance with GAAP, we believe that certain non-GAAP financial measures, including Adjusted EBITDA and Adjusted EBITDA Margin, are useful in evaluating our business. A metric similar to Adjusted EBITDA is used in certain calculations under our New Revolving Credit Facility. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by total revenue. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as substitutes for an analysis of our results as reported under GAAP. In addition, other companies in our industry may calculate non-GAAP financial measures differently than we do, limiting their usefulness as a comparative measure. The following table presents a reconciliation of Adjusted EBITDA, a non-GAAP financial measure, to the most directly comparable financial measure prepared in accordance with GAAP.

Other (income) (d)		(49	)		(320	)
Adjusted EBITDA	$	21,725		$	15,385
Adjusted EBITDA margin		32	%		30	%

(a)

M&A (recoveries) costs for the three months ended March 31, 2021 and 2020 consist of third-party costs and deferred compensation costs related to acquisitions.

(b)

Offering costs and IPO readiness costs for the three months ended March 31, 2021 and 2020 consist of third-party costs incurred in preparation for our IPO.

(c)

Other costs for the three months ended March 31, 2021 and 2020 consist of reimbursements paid to Providence. For the three months ended March 31, 2020, other costs also include costs related to the departure of our former Chief Executive Officer, and third-party costs incurred in response to investigating and remediating certain IT/cybersecurity matters that occurred in March 2020.

(d)

Other (income) consists of interest income, change in fair value associated with contingent considerations, and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities.

We use Adjusted EBITDA and Adjusted EBITDA Margin as measures of operational efficiency to understand and evaluate our core business operations. We believe that these non-GAAP financial measures are useful to investors for period to period comparisons of our core business and for understanding and evaluating trends in our operating results on a consistent basis by excluding items that we do not believe are indicative of our core operating performance.

These non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as substitutes for an analysis of our results as reported under GAAP. Some of the limitations of these measures are:

they do not reflect changes in, or cash requirements for, our working capital needs;

Adjusted EBITDA does not reflect our capital expenditures or future requirements for capital expenditures or contractual commitments;

they do not reflect income tax expense or the cash requirements to pay income taxes;

they do not reflect our interest expense or the cash requirements necessary to service interest or principal payments on our debt; and

although depreciation and amortization are non-cash charges related mainly to intangible assets, certain assets being depreciated and amortized will have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.

In addition, other companies in our industry may calculate these non-GAAP financial measures differently than we do, limiting their usefulness as a comparative measure. You should compensate for these limitations by relying primarily on our GAAP results and using the non-GAAP financial measures only supplementally. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by total revenue.
