Item 1.01. Entry into a Material Definitive Agreement

On April 1, 2014, Vistaprint N.V. and its wholly owned subsidiary, Vistaprint Italy S.r.l., entered into a Sale and Purchase Agreement with Alcedo SGR S.p.A (on behalf of the close-ended investment fund “Alcedo III”), Cap2 S.r.l., and Alessandro Tenderini pursuant to which Vistaprint Italy agreed to acquire 97 percent of the outstanding corporate capital of Pixartprinting S.r.l., a limited liability company incorporated under the laws of Italy, as follows:

Pursuant to the Sale and Purchase Agreement, Vistaprint agreed to pay an aggregate base purchase price of approximately €127 million and a sliding-scale earn out of up to €9.6 million subject to Pixartprinting’s achievement of certain revenue and EBITDA performance targets for calendar year 2014. To secure the indemnification obligations of Cap2 and Alcedo under the Sale and Purchase Agreement, Cap2 pledged the Cap2 Retained Equity to Vistaprint, and €6 million of the purchase price payable to Alcedo was deposited into an escrow fund. On or about October 3, 2015, the equity pledge will terminate with respect to any amount of the Cap2 Retained Equity that has not been transferred to Vistaprint to cover indemnification claims, and Alcedo will receive the balance of the escrow fund on such date less (1) any amounts held for unresolved indemnification claims and (2) €1 million to be held until December 31, 2019 to secure certain tax indemnification obligations.

Vistaprint N.V. and Vistaprint Italy have also entered into Put and Call Option Agreements with each of Cap2 and Mr. Tenderini with respect to the Cap2 Retained Equity and, if Mr. Tenderini exercises the purchase right described above, the CEO Retained Equity. Pursuant to the Put and Call Option Agreements, Cap2 and Mr Tenderini have the right to sell to Vistaprint all (but not less than all) of each of the Cap2 Retained Equity and CEO Retained Equity at the end of Pixartprinting’s fiscal years ending June 30, 2015, 2016 and 2017 for a purchase price based on Pixartprinting’s EBITDA and net financial position (as reflected in its annual financial statements) for the fiscal year as to which the put option is exercised. Vistaprint has the right to buy from Cap2 and Mr. Tenderini all (but not less than all) of each of the Cap2 Retained Equity and CEO Retained Equity at the end of Pixartprinting’s fiscal years ending June 30, 2017 and 2018 for a purchase price based on Pixartprinting’s EBITDA and net financial position (as reflected in its annual financial statements) for the fiscal year as to which the call option is exercised. The parties’ put and call rights are also triggered by certain other events described in the Put and Call Option Agreements. The put and call options are exercisable during 30-day periods following the determination of the option purchase price for the relevant fiscal year.

This description is not a complete description of the parties’ rights and obligations under the Sale and Purchase Agreement and Put and Call Option Agreements and is qualified by reference to the full text of the agreements, which are filed as exhibits to this report and incorporated herein by reference.
