Exhibit 99.4

Letter to Business Leaders

To Business Leaders,

Today we announced that our Board of Directors approved entering into a definitive agreement for Intermec to be acquired by Honeywell International Inc. for $10.00 per share in an all-cash transaction, representing a total transaction value of approximately $600 million, net of debt and cash acquired. A copy of the press release is attached.

As you know, several months ago our Board announced that it was conducting a comprehensive review of the business and exploring strategic alternatives to determine the most promising path forward. After extensive discussion and thoughtful consideration, the Board determined that accepting Honeywell’s offer was a good result for our constituents. By merging with Honeywell, Intermec will enjoy greater scale and resources to better compete.

We expect the transaction to close by the end of the second quarter 2013, but until then it is business as usual. Intermec will operate as an independent company, committed to our strategies and, in particular, to supporting our customers and business partners.

I know there are many questions, so please encourage your team to join me at a town hall in the auditorium, on the phone or online at 9:00 AM Everett time today (a second Town Hall will take place for everyone in Asia Pac at 5:00 PM). I will share with you my expectations for the next several months and try to answer as many of your questions as possible. The dial-in number is 1-877-668-4490 and the access code is xxx xxx xxx or to join the webcast at 9:00 AM, please click here.

While we are not yet in a position to address each and every question right now, I am committed to being as transparent as possible and communicating as much as we are permitted to when we can.

Many of you will play an important role in going forward and when planning gets underway we will provide more detail and clarity as to roles and responsibilities. The most important contribution you can all make at this time is to continue to meet your goals and budgets and ensure our customers and partners get the products, service and support they’ve come to expect from us. Finally, I ask that you also remind everyone to direct all media calls to Nikolett Bacso. It is important that we not speculate with customers, partners, vendors or others about what this transaction may or may not mean, and that only authorized spokespeople speak for the company.

We should all be very proud of what we have accomplished, and that the tremendous value we’ve created here at Intermec has been recognized by the industry. I am privileged to be part of an extraordinary team of people at Intermec and want to thank you, our leaders, for your ongoing dedication and commitment.

Thank you,

Al
