Citrix Systems Inc beat the Wall Street estimates for its third quarter earnings in spectacular fashion yesterday, coming in with $0.44 per share when the consensus was for $0.31 per share, and enjoying margins most software companies can only dream of. The Fort Lauderdale, Florida supplier of thin client and server software to run multi-user Windows NT applications turned in reported third quarter net income up 146% at $13.1m, on revenues that rose 199% to $34.9m. It signed licensing deals for its Independent Computing Architecture ((ICA) protocol with Cruise technologies and Umax Data Systems and launched version 1.7 of its WinFrame NT server. Citrix has a limited time making hay while the sun shines, as following its deal with Microsoft Corp earlier this year whereby Microsoft will embed its own Hydra multi-user technology into future version NT, but permit Citrix to carry on selling WinFrame as a separate product. Cash stood at $220.1m at the quarter’s end.
