Stanley Black & Decker Announces EU Antitrust Clearance Regarding Its Recommended All-Cash Offer To Acquire All Shares And Warrants In Niscayah

New Britain, Connecticut, August 23, 2011

Stanley Black & Decker, Inc. (NYSE: SWK) (“Stanley Black & Decker”) announced today that it has received antitrust clearance from the European Commission for its recommended all-cash offer, through a tender offer by its indirect wholly-owned subsidiary SBD Holding AB, to acquire all class A and class B shares and warrants in Niscayah Group AB (publ) (OMX: NISC), a leading commercial security and monitoring company specializing in electronic security services and solutions based in Stockholm, Sweden, for SEK 18.00 per share and SEK 0.05 per warrant in cash (the “Offer”). All antitrust conditions to the Offer have now been satisfied.

The Offer represents a premium of approximately 47% compared to Niscayah’s closing price¹ prior to the announcement of Securitas’ offer to acquire Niscayah on May 16, 2011, and a premium of approximately 15% compared to Niscayah’s stock price at close on June 23, 2011 (the last trading day prior to the announcement of the Offer). At announcement, the Offer represented a premium of approximately 24% to the then value of Securitas’ all-stock offer. The independent committee of the board of directors of Niscayah has unanimously recommended that shareholders and warrant holders in Niscayah accept the Offer. Niscayah shareholders representing approximately 19.5%² of the shares in Niscayah have committed to accept the Offer, subject to certain conditions.

Stanley Black & Decker has acquired in total 72,005,890 class B shares of Niscayah, representing approximately 19.8% of the outstanding shares³ and approximately 13.9% of the total number of votes in Niscayah, at prices not exceeding SEK 18, through purchases outside of the Offer. This accumulation of shares reflects Stanley Black & Decker’s commitment to the tender offer announced on June 27, 2011.

The acceptance period for the Offer is scheduled to expire on September 1, 2011.⁴
