(NASDAQ: PCTI), a leader in simplifying broadband mobility, announced today that it has acquired all of the shares of Sigma Wireless Technologies Limited (SWT) from the Sigma Communications Group Limited, one of Ireland's leading telecommunications and mobile companies. SWT is based in Dublin and develops and distributes innovative antennas for public safety and for the rapidly growing UMTS cellular networks. The newly acquired operation, which comprises over 100 employees, will become part of PCTEL's Antenna Products Group (APG), which is led by Steve Deppe. The purchase consideration paid by PCTEL at the closing included (euro)19.5 million in cash and the assumption of approximately (euro)2.5 million in pension liability. The total acquisition price was (euro)22 million or approximately $27 million. The selling stockholders of SWT may also earn up to an additional (euro)7.5 million ($9.1 million) in cash based on SWT's revenue performance over the 18-month period ending December 31, 2006. Transaction fees will be approximately $1.7 million. The acquisition establishes a European presence for PCTEL, whose antenna sales to date have been principally in North and South America and China. In addition, the acquisition positions PCTEL in the rapidly growing UMTS infrastructure market with leading edge antenna technology and associated control systems. The new generation of cellular technology requires frequent optimization and the ability to manage clusters of antennas. SWT's IVET(TM) (Integrated Variable Electrical Tilt) antenna technology permits cellular networks to remotely adjust and optimize coverage areas and antenna clusters in response to key network performance parameters, such as signal to noise ratios. Adjustable Remote Tilt or Remote Electrical Tilt (RET) antennas permit operators to adjust - using laptop computers or handheld devices - an antenna's tilt angle. The ability to remotely control UMTS antennas with SWT's BLUSTREAM(TM) antenna management system eliminates serial re-design, the costly process of gaining access to an antenna site, and shutting down transmitter sites in order to make the adjustments. Operators anticipate that iVET deployment will result in both improved Quality of Service (QoS) and lower costs. These products are being deployed within some of Europe's largest cellular networks. Joe Moore, SWT's current General Manager, will continue in that capacity, reporting to Steve Deppe. Mr. Moore will also serve as PCTEL's Vice-President, European Operations. "The iVET antenna technology gives PCTEL a strong position in the rapidly growing 3G cellular broadband market, an important target for our company," said Marty Singer, PCTEL's Chairman and CEO. "We believe in pervasive wireless broadband and we are now in a better position to compete in that space. We are also excited about establishing a stronger European sales presence, expanding our revenue base, and taking the next step in our continued efforts to build a formidable wireless company. First and foremost, though, we view this as an important technology acquisition," added Singer. "On behalf of the Sigma Wireless Technologies team, we are delighted to become part of PCTEL," said Joe Moore. "We believe in the application of our technology platforms, specifically our iVET, Blustream and FUSION(TM) products, to 3G and the implementation of new cellular networks. We are convinced that with PCTEL's resources and related technologies in RF scanning, we can successfully distribute our products worldwide," added Moore. "We welcome the acquisition of Sigma Wireless Technologies by PCTEL as offering the best prospects for the continued global development of the company," said Tony Boyle, Chief Executive of the Sigma Communications Group. "We are delighted that our significant investment in R&D will lead to the worldwide exploitation of the innovative technology we developed here," added Boyle. In addition to its iVET product line, SWT provides Private Mobile Radio (PMR) and Digital Private Mobile Radio (DPMR) antenna solutions. PMR and DPMR are used in a variety of public utility and public safety applications. DPMR is based on the European TETRA technology (similar to iDEN, the basis for NEXTEL services). TETRA has been adopted as the DPMR solution in over 70 countries. SWT designs and manufactures TETRA antennas and pioneered the first "cross-polarized" panel antennas and inter-modulation protected (IMP) designs. SWT supplies nationwide networks in over 10 countries. Robert W. Baird & Co. acted as financial advisor to PCTEL Inc. in this transaction.
