The revenue growth reflects solid demand in all regions across both the Government and Enterprise segments.

“Our record fourth quarter capped a very strong and exciting year for our company,” said Greg Brown, chairman and CEO of Motorola Solutions. “We streamlined and strengthened our portfolio, grew operating earnings more than five times revenue growth, expanded operating margins, generated strong cash flow and prioritized return of capital to our shareholders.”

Conference Call and Webcast

Use of Non-GAAP Financial Information

In addition to the GAAP results included in this presentation, Motorola Solutions also has included non-GAAP measurements of results. We have provided these non-GAAP measurements to help investors better understand our core operating performance,

enhance comparisons of core operating performance from period to period and allow better comparisons of operating performance to our competitors. Among other things, management uses these operating results, excluding the identified items, to evaluate performance of the businesses and to evaluate results relative to certain incentive compensation targets. Management uses operating results excluding these items because it believes this measurement enables it to make better period-to-period evaluations of the financial performance of core business operations. The non-GAAP measurements are intended only as a supplement to the comparable GAAP measurements and the company compensates for the limitations inherent in the use of non-GAAP measurements by using GAAP measures in conjunction with the non-GAAP measurements. As a result, investors should consider these non-GAAP measurements in addition to, and not in substitution for or as superior to, measurements of financial performance prepared in accordance with GAAP.

Highlighted items: The company has excluded the effects of highlighted items (and any reversals of highlighted items recorded in prior periods) from its non-GAAP operating expenses and net income measurements because the company believes that these historical items do not reflect expected future operating earnings or expenses and do not contribute to a meaningful evaluation of the company’s current operating performance or comparisons to the company’s past operating performance.

Stock-based compensation expense: The company has excluded stock-based compensation expense from its non-GAAP operating expenses and net income measurements. Although stock-based compensation is a key incentive offered to our employees and the company believes such compensation contributed to the revenue earned during the periods presented and also believes it will contribute to the generation of future period revenues, the company continues to evaluate its performance excluding stock-based compensation expense primarily because it represents a significant non-cash expense. Stock-based compensation expense will recur in future periods.

Intangible assets amortization expense: The company has excluded intangible assets amortization expense from its non-GAAP operating expenses and net income measurements, primarily because it represents a significant non-cash expense and because the company evaluates its performance excluding intangible assets amortization expense. Amortization of intangible assets is consistent in amount and frequency but is significantly affected by the timing and size of the company’s acquisitions. Investors should note that the use of intangible assets contributed to the company’s revenues earned during the periods presented and will contribute to the company’s future period revenues as well. Intangible assets amortization expense will recur in future periods.

Details of the above items and reconciliations of the non-GAAP measurements to the corresponding GAAP measurements can be found at the end of this press release.
