ISS publishes Offering Circular and sets indicative price range for its IPO

This announcement does not constitute an offering circular and nothing herein contains an offering of securities. No one should purchase or subscribe for any securities in ISS A/S ("ISS") except on the basis of information in the offering circular published by ISS in connection with the offering and admission of such securities to trading and official listing on NASDAQ OMX Copenhagen A/S ("NASDAQ OMX Copenhagen"). Copies of the offering circular are available from ISS' registered office and on ISS' website.

ISS, one of the world's leading facility services companies, today publishes its Offering Circular and sets the indicative price range for the intended initial public offering ("IPO" or the "Offering") of its shares and for the admission of its shares to trading and official listing on NASDAQ OMX Copenhagen.

The IPO is expected to support ISS' future growth and operational strategy, advance the company's public and commercial profile, provide ISS with improved access to public capital markets and a diversified base of new Danish and international shareholders.

In connection with the IPO, a limited sell-down of existing ordinary shares will be undertaken by certain funds advised by EQT Partners and funds advised by affiliates of The Goldman Sachs Group, Inc. indirectly through a co-owned entity (the "Selling Shareholder"). This partial sell-down is primarily reserved for ISS to purchase shares to meet certain obligations under the incentive programmes.

OTPP and KIRKBI are not selling shares in connection with the IPO.

Jeff Gravenhorst, ISS' Group CEO, commented:

"Since we announced our intention to launch an IPO, we have received very positive feedback from both potential investors and other stakeholders. We are very pleased to announce today the start of the public offering process and to initiate this important phase of our strategic development. Following another set of solid financial results, ISS is well positioned for a listing on the

stock exchange and we look forward to inviting new shareholders into the ownership structure and building strong relationships with them."
