Section 2 — Financial Information

Item 2.02 — Results of Operations and Financial Condition

On February 2, 2012, Harris Interactive Inc. (the “Company”) issued a press release announcing the Company’s earnings for the fiscal quarter ended December 31, 2011. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

The following non-GAAP financial measures are referenced in the press release attached as Exhibit 99.1: adjusted EBITDA and adjusted EBITDA after the effect of restructuring and other charges. A reconciliation of these non-GAAP measures to the most directly comparable financial measure calculated and presented in accordance with GAAP, GAAP Net Income, is provided as part of the press release.

These non-GAAP financial measures should not be considered in isolation; they are in addition to, and are not a substitution, for financial performance measures under GAAP. These non-GAAP financial measures may be different from non-GAAP measures used by other companies. Further, we may utilize other measures to illustrate performance in the future. Non-GAAP measures have limitations since they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP.

The Company defines Non-GAAP Adjusted EBITDA as earnings before interest expense (income), income taxes, depreciation and amortization, and stock based compensation. Non-GAAP Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. The Company is presenting Non-GAAP Adjusted EBITDA because it provides investors with an additional way to view its operations, when considered with both its GAAP results and the reconciliation to net income, which the Company believes provides a more complete understanding of its business than could be obtained absent this disclosure. Non-GAAP Adjusted EBITDA is presented solely as a supplemental disclosure because: (i) the Company believes it is a useful tool for investors to assess the operating performance of the business without the effect of non-cash depreciation, amortization and stock based compensation expenses; (ii) the Company believes that investors will find this data useful in assessing its ability to service or incur indebtedness; and (iii) Non-GAAP Adjusted EBITDA is a component of the financial covenant measures used by the Company’s lenders in connection with the Company’s credit facilities. The use of Non-GAAP Adjusted EBITDA has limitations and should not be considered in isolation from or as an alternative to GAAP measures, such as net income, operating income or other data prepared in accordance with GAAP, or as a measure of the Company’s profitability or liquidity.

The Company believes that its description of Non-GAAP Adjusted EBITDA after the effect of restructuring and other charges is useful to investors because it provides a means for investors to better understand the Company’s ongoing operations during the fiscal quarter.

Section 5 — Corporate Governance and Management

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Director Compensation

Specifically, Mr. Gould will receive an additional cash retainer of $25,000, payable in equal monthly installments during this three month period, and a restricted stock grant of 15,000 shares that vest ratably on February 29, 2012, March 31, 2012 and April 30, 2012.

Director Resignation

On February 1, 2012, Marty Beard, a director of the Company, notified the Board that he has decided to resign from the Board, effective immediately, in order to devote more time to his recently increased responsibilities as President and Chief Executive Officer of LiveOps Inc., a provider of cloud-based contact center solutions.

Mr. Beard’s decision to resign was not related in any manner to any past, present, or contemplated accounting, finance or legal issue, or to any disagreement with the Board or management over any issue or policy, including any accounting-related policy.
