In 2015, Honeywell International Inc. (NYSE: HON) reported almost $40 billion in sales. It has successfully solidified itself as a Fortune 100 company by expanding into numerous industries and offering varying products. Honeywell’s success is partially attributable to the numerous acquisitions that it has completed. In fact, Honeywell’s five-year strategic plan from 2014 to 2018 called for $10 billion in mergers and acquisition spending. Without these subsidiaries, Honeywell’s operations would not be as diversified in regards to products, geographical location or industry.

Elster Group

As of 2016, Honeywell’s largest acquisition to date was of Elster Group from Melrose Industries PLC (MRO.L). The acquisition was completed for $5.1 billion. Honeywell was attracted to Elster Group’s high-growth product areas and geographical locations. Elster Group is a leading provider of gas, electricity and water meters, including all associated communications and software solutions. It reported gross assets of approximately $2.8 billion in 2015 and employs just under 7,000 individuals.

EMS Technologies, Inc.

For $500 million, Honeywell purchased EMS Technologies. The deal expanded Honeywell’s position in the global scanning and mobility industry. EMS Technologies specializes in rugged handheld vehicle-based products. Items sold within the aviation department include rugged data storage, surveillance applications, antennas and terminals. The acquisition was completed in 2011.

Intelligrated

Honeywell acquired Intelligrated in July 2016 for $1.5 billion in cash.

Intermec will be integrated into Honeywell’s scanning and mobility division.

Its Otter, King’s and Oliver brands of steel-toe-capped boots are sold primarily in Australia, Asia and Europe. Honeywell’s motivation for completing the deal was tied to bolstering its workplace safety equipment segment of business.
