CONTENTS

On September 4, 2014, Matrix IT Ltd. (“Matrix”), a subsidiary of Formula Systems (1985) Ltd. (“we,” “us,” “Formula” or the “Company”), received from one of Matrix’s shareholders a request for a class action lawsuit, as well as a related claim letter for such a lawsuit that named each of Matrix, certain of its directors, its chief executive officer and Formula, as the controlling shareholder of Matrix. The claim and class action request relate to alleged damages suffered by Matrix shareholders due to Matrix’s financial statements having included misleading information that, according to the claimant, constituted a violation of Matrix’s reporting obligations under the Israeli Securities Law. The claim was asserted in the aftermath of Matrix’s report that it had corrected certain mistakes that had been discovered in its historical financial statements.

The claimant alleges that he suffered personal damages of NIS 535, while also claiming that the shareholders of Matrix suffered collective damages amounting to NIS 30 million, in the aggregate.

We are reviewing the claims in coordination with Matrix and will file our response in due course. At this early stage, we cannot accurately estimate the likelihood of our (or Matrix’s) success in defending the claim.
