“Safe harbor” Statement:

This press release contains forward-looking statements that involve risks, uncertainties, assumptions and other factors that could cause actual results and the timing of certain events to differ materially from those set forth in or implied by such forward-looking statements. All

statements other than statements of historical fact are forward-looking statements, including, but not limited to, statements related to Tremor Video’s future financial results or growth potential, including 2013 third quarter and year-end financial guidance.

Important factors that could cause actual results or the timing of events to differ materially from those set forth in or implied by any forward-looking statements include, without limitation, risks and uncertainties associated with: the company’s limited operating history and the continuing development of its business model; unfavorable conditions in the global economy or reductions in digital advertising spend; the company’s ability to effectively innovate and adapt to rapidly changing technology and client needs; increased competition as well as innovations by new and existing competitors; expansion of the online video advertising market; the company’s ability to attract new advertisers and increase spend from existing advertisers; adoption of brand-centric metrics, advanced ad formats and performance-based pricing models by advertisers; the company’s ability to acquire an adequate supply of premium video advertising inventory from publishers on terms that are favorable to it; the company’s ability to detect fraudulent or malicious activity and ensure a high level of brand safety for its clients; identifying, attracting and retaining qualified personnel; defects, errors or interruptions in the company’s solutions; the company’s ability to collect and use data to deliver video ads; the effect of regulatory developments and industry standards regarding internet privacy and other matters; maintaining, protecting and enhancing the company’s intellectual property; costs associated with defending intellectual property infringement and other claims; future opportunities and plans, including the uncertainty of expected future financial performance and results; as well as other risks and uncertainties detailed from time-to-time under the caption “Risk Factors” and elsewhere in Tremor Video’s filings with the Securities and Exchange Commission, including its prospectus filed with the Securities and Exchange Commission on June 27, 2013 pursuant to Rule 424(b)(4) under the Securities Act (File No. 333-188813), and future filings and reports by the company, including its Form 10-Q for the quarter ended June 30, 2013.

Non-GAAP Financial Measures

To supplement its consolidated financial statements, which are prepared and presented in accordance with U.S. generally accepted accounting principles (“GAAP”), Tremor Video reports Adjusted EBITDA and basic and diluted Adjusted EBITDA per share which are non-GAAP financial measures. We define Adjusted EBITDA as net loss plus (minus): other (income) expense, net, interest expense, income tax expense, depreciation and amortization expense and non-cash stock-based compensation expense. We define Adjusted EBITDA per share as Adjusted EBITDA divided by weighted average common shares outstanding. We use these non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. We believe that these measures provide useful information about operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making. Non-GAAP financial measures should be considered in addition to results and guidance prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. The non-GAAP financial measures included in this press release have been reconciled to the nearest GAAP measure in the table following the financial statements attached to this press release. With

respect to our expectations under “Guidance” above, reconciliation of Adjusted EBITDA guidance to the closest corresponding GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to the charges excluded from these non-GAAP measures, in particular, the measures and effects of stock-based compensation expense specific to equity compensation awards that are directly impacted by unpredictable fluctuations in our stock price. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.

(1) On July 2, 2013, Tremor Video closed its initial public offering (“IPO”) of common stock in which Tremor Video issued and sold 7,500,000 shares of common stock for which the company received $66.8 million of net proceeds after deducting underwriting discount, commissions and offering costs of approximately $8.2 million. Upon the closing of the IPO, all of Tremor Video’s

outstanding mandatorily redeemable convertible preferred stock (“preferred stock”) automatically converted into 34,172,316 shares of common stock and all of Tremor Video’s outstanding Series II common stock automatically converted into 1,052,464 shares of common stock. In addition, the outstanding warrants to purchase preferred stock automatically converted into warrants to purchase 142,534 shares of common stock, and the warrants to purchase preferred stock liability of $0.8 million, which includes a $0.1 million adjustment for the change in fair value through July 2, 2013, was reclassified to additional paid-in capital. The pro forma stockholders’ equity, as set forth on the pro forma June 30, 2013 consolidated balance sheet, has been adjusted to reflect the assumed: (i) conversion of the company’s preferred stock and Series II common stock into common stock, and 1,584,863 additional shares of common stock issued upon the conversion of our Series F preferred stock at the IPO price of $10.00 per share, (ii) conversion of the company’s warrants to purchase preferred stock into warrants to purchase common stock, and the reclassification of such warrants from preferred stock liability to additional paid-in capital and (iii) the sale and the issuance of 7,500,000 shares of common stock and the receipt of net proceeds upon the closing of the IPO.

Tremor Video believes that the pro forma consolidated balance sheet provides material information to investors, as the conversion of Tremor Video’s preferred stock and Series II common stock to common stock, conversion of the warrants to purchase preferred stock to common stock warrants and the closing of the IPO occurred on July 2, 2013, and therefore the disclosure of the pro forma consolidated balance sheet provides measures of equity that are comparable to what will be reported by Tremor Video in its consolidated financial statements for the periods subsequent to and including July 2, 2013.

(1) The pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders for the three months ended June 30, 2013 has been adjusted to reflect, as of April 1, 2013, the assumed completion of Tremor Video’s IPO and the: (i) conversion of all outstanding shares of the company’s preferred stock into an aggregate of 34,172,316 shares of common stock, (ii) conversion of all the company’s outstanding shares of Series II common stock into an aggregate of 1,052,464 shares of common stock and (iii) conversion of the company’s warrants to purchase preferred stock to warrants to purchase 142,534 shares of common stock. Pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders in the table above includes the effects of a $15.9 million preferred stock deemed dividend for the assumed fair value of 1,584,863 additional shares of common stock issued upon the conversion of our Series F preferred stock at the IPO price of $10.00 per share and a $0.1 million adjustment for the change in fair value through July 2, 2013 upon conversion of the warrants to purchase preferred stock to warrants to purchase common stock.

Tremor Video believes that the pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders provides material information to investors, as the conversion of Tremor Video’s preferred stock and Series II common stock to common stock, conversion of the warrants to purchase preferred stock to common stock warrants and the closing of the IPO occurred on July 2, 2013, and therefore the disclosure of the pro forma net loss attributable to common stockholders and pro forma net loss per share attributable to common stockholders provides measures of net loss and net loss per share that are comparable to what will be reported by Tremor Video in its consolidated financial statements for the periods subsequent to and including July 2, 2013.
