TEL AVIV, Israel & NEW YORK--(BUSINESS WIRE)--Perion Network Ltd. (NASDAQ: PERI), a global advertising technology company that delivers its Synchronized Digital Branding solution across the three main pillars of digital advertising - ad search, social media and display / video / CTV advertising today announced preliminary results for the fourth quarter and full year 2020. Management now expects to exceed the previously announced guidance for both revenue and Adjusted EBTIDA. Additionally, the Company has pre-announced anticipated results for GAAP EPS and non-GAAP EPS. Based on a preliminary (unaudited) review, the Company anticipates: We have provided a range for the preliminary unaudited estimated results described primarily because our financial closing procedures for the three and twelve months ended December 31, 2020 are not yet complete. As a result, there is a possibility that our final results will vary materially from these preliminary estimates. We currently expect that our final results will be within the ranges described above. It is possible, however that our final results will not be within the ranges we currently estimate. We have estimated a charge of $0.2 million for revaluation of payment obligations related to acquisitions. The actual charge (benefit) could differ significantly as we and our advisors finalize this valuation. Any such change could lead to our GAAP Net Income and GAAP EPS differing from the estimates set forth above. The following table sets forth a reconciliation of non-GAAP diluted earnings per share to GAAP diluted earnings per share.

Perion is a global technology company that delivers strategic business solutions that enable brands and advertisers to efficiently and successfully Capture and Convince users across multiple platforms and channels, including interactive connected television or iCTV. Perion achieves this through its Synchronized Digital Branding capabilities, which are focused on high impact creative; content monetization; its branded search network, in partnership with Microsoft Bing; and social media management that orchestrates and optimizes paid advertising. This diversification positions Perion for growth as budgets shift across categories. Non-GAAP measures Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization ("Adjusted EBITDA") is defined as operating income excluding stock-based compensation expenses, depreciation, restructuring costs, acquisition related items consisting of amortization of intangible assets and goodwill and intangible asset impairments, acquisition related expenses, gains and losses recognized on changes in the fair value of contingent consideration arrangements and certain accounting entries under the business combination accounting rules that require us to recognize a legal performance obligation related to revenue arrangements of an acquired entity based on its fair value at the date of acquisition. The purpose of such adjustments is to give an indication of our performance exclusive of non-cash charges and other items that are considered by management to be outside of our core operating results. These non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. Furthermore, the non-GAAP measures are regularly used internally to understand, manage and evaluate our business and make operating decisions, and we believe that they are useful to investors as a consistent and comparable measure of the ongoing performance of our business. However, our non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. Additionally, these non-GAAP financial measures may differ materially from the non-GAAP financial measures used by other companies.
