United Technologies, a manufacturing conglomerate with products ranging from jet engines to elevators, said Monday it will break up into three separate companies.

One of the new companies, which will keep the name United Technologies, will contain its Pratt & Whitney aerospace business along with Rockwell Collins, an acquisition that will also close Tuesday. A second company will be called Otis, manufacturing elevators and escalators. A third, Carrier, will make heating and air-conditioning systems along with fire safety and security products.

The investor-relations site for United Technologies’ included a notice of a conference call with analysts and investors, scheduled for 8am ET Tuesday, to discuss the move. The company also made a brief announcement of the move on Twitter.

“Our decision to separate United Technologies is a pivotal moment in our history and will best position each independent company to drive sustained growth,” CEO Gregory Hayes said in a statement. “As standalone companies, United Technologies, Otis and Carrier will be ready to solve our customers’ biggest challenges.”

Analysts and investors have been speculating about the possibility of breaking up United Technologies for some time. More recently, activist investors, including Bill Ackman of Pershing Square and Dan Loeb of Third Point, have been pressuring United Technologies to break up into separate companies, arguing that the individual businesses would be more likely to trade at fair value on their own.

United Technologies is one of the oldest component stocks in the Dow Jones Industrial Average, entering the closely watched index in 1939, when it was named United Aircraft. The company expanded into other areas of manufacturing over the decades. It’s not clear whether the stock will be replaced in the Dow Jones Industrial Average.

In October, United Technologies said it expects revenue in 2018 to reach as high as $64.5 billion in 2018, which would mark a 7.8% increase from its 2017 revenue. United Technologies’ stock was trading as much as 2.4% higher in after-hours trading on the news.

制造业巨头联合技术公司周一称，公司将拆分为三家独立的公司。这家制造业巨头的产品涵盖喷气机发动机和电梯等。

其中一家新公司将沿用联合技术的名称，该公司由普惠太空业务以及将于周二完成收购的罗克韦尔柯林斯业务组成。第二家公司名为奥的斯，专注于制造电梯和扶梯。第三家公司名为开利，将专注于生产加热和空调系统以及消防安全和安保产品。

联合技术的投资者关系网站发布了一则通知，公司于美国东部时间周二早上8点召开分析师和投资者电话会议，以讨论这一拆分举措。公司还围绕该举措在推特上发表了简短声明。

首席执行官格里高利·哈耶斯在一则声明中表示：“拆分联合技术公司的决定是公司历史上一个重要的时刻。此举旨在让每家独立公司获得最大的优势，从而实现各个公司的可持续增长。作为独立的公司，联合技术、奥的斯和开利将随时帮助客户解决其面临的最严谨挑战。”

分析师和投资者讨论联合技术的拆分已经有一段时间了。最近，包括Pershing Square公司比尔·阿克曼和Third Point公司丹·罗伊布在内的激进投资者一直在给联合技术施压，逼迫其拆分成独立的公司。他们认为拆分之后的独立公司在交易时能更好地体现其各自的公允值。

联合技术是道琼斯工业平均指数中历史最为悠久的成员股之一，它于1939年进入了密切关注指数，当时公司曾更名为United Aircraft。公司在过去的数十年时间中将业务拓展至其他制造领域。我们尚不清楚该股票在道琼斯工业平均指数中是否会被替代。

今年10月，联合技术公司表示，公司2018年营收预计高达645亿美元，同比增长7.8%。消息公布之后，联合技术公司股价在当日收盘前的最高涨幅达到了2.4%。（财富中文网）
