Item 2.02. Results of Operations and Financial Condition.

Saba Software, Inc. (the “Company”) issued a press release on September 17, 2013 disclosing, among other items, guidance regarding certain updated preliminary financial information and metrics for its fiscal year ended May 31, 2013. A copy of the Company’s press release is furnished hereto as Exhibit 99.1.

The information in Item 2.02 of this Form 8-K and Exhibit 99.1 are furnished to, but not filed with, the Securities and Exchange Commission (“SEC”). The information contained in Item 2.02 of this Form 8-K and in Exhibit 99.1 shall not be incorporated by reference to any filing of the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference to such filing.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the federal securities laws, including, without limitation, the Company’s current progress and timing objectives regarding completion of its accounting restatement and becoming current in its required filings with the SEC, and the Company’s objective to obtain prompt readmission to the NASDAQ Global Select Market and to have its shares of common stock trade on that market following completion of the restatement and compliance with applicable listing requirements. The actual outcome of these matters could differ materially from those expressed in any forward-looking statements due to, among other things, the Company’s ability to complete the work required for the restatement of its financial statements in a timely manner, any additional required adjustments to the Company’s financial statements and/or other factors arising in the restatement process that are not currently known or identified or where the scope of work required or impact of the restatement may be greater than what is currently known or anticipated by the Company, the possibility that the restatement or matters related to the restatement may give rise to shareholder litigation or legal proceedings that are adverse to the Company and the impact of the restatement on the Company’s sales, operations and financial performance. In addition, the Company faces risks and uncertainties that could affect timing of the completion of its restatement and becoming current with respect to its delayed filings with the SEC including material weaknesses that exist with respect to its internal controls over financial reporting or additional deficiencies in its internal controls over financial reporting that may be identified. Readers should refer to the section entitled “Risk Factors” in the Form 10-K for the fiscal year ended May 31, 2011, and similar disclosures in subsequent reports filed with the SEC. The forward-looking statements and risks stated in this press release are based on information available to the Company today. The Company assumes no obligation to update them.
