Jason J. Winkler
Executive Vice President and Chief Financial Officer at Motorola Solutions
Thank you, Greg.
Revenue for the quarter grew 17% with record fourth-quarter revenue in both segments and in all three technologies. Revenue exceeded our guidance and was driven by supply chain execution during the quarter, enabling higher product revenues in LMR. FX headwinds during the quarter were $87 million, while acquisitions added $39 million.
GAAP operating earnings were $692 million, up 26% versus last year and GAAP operating margins were 25.6% compared with 23.7% in the prior year. Non-GAAP operating earnings were $822 million [Technical Issues] was 30.4%, up from 28.9%. This was Motorola Solutions' first-ever quarter of over 30% operating margin and was driven by the higher sales in both segments and the improved operating leverage, particularly in the Products and SI segment.
GAAP earnings per share was $3.43, up from $2.30 in the year-ago quarter on higher sales and on a lower effective tax rate, driven primarily by a $47 million or $0.27 per share tax benefit from the release of a valuation allowance against US foreign tax credits. Non-GAAP EPS was $3.60, up 26% from $2.85 last year, driven by higher sales and improved operating leverage. Opex in Q4 was $541 million, up $21 million versus last year, primarily due to acquisitions and higher incentives.
For the full-year 2022, revenue was $9.1 billion, up 12% with strong growth in both segments and across all three technologies. The impact from unfavorable currency was $216 million and revenue from acquisitions was $121 million. GAAP operating earnings were $1.7 billion or 18.2% of sales versus 20.4% in the year prior. The decrease was primarily driven by the $147 million non-cash fixed asset impairment recognized in the current year related to our exit of ESN.
Non-GAAP operating earnings were $2.4 billion, up $251 million and non-GAAP operating margins were 26% of sales, up from 25.9% in the year prior, driven by higher sales and improved operating leverage, partially offset by higher material costs, and higher expenses from acquisitions. GAAP earnings per share was $7.93, up 11% compared to the $7.17 in the year prior, driven by higher sales, a lower effective tax rate and partially offset by the asset impairment charge related to the ESN exit and higher material costs.
Non-GAAP earnings per share was $10.36, up 13% from $9.15 in 2021 on higher sales, improved -- and improved operating leverage, partially offset by higher material costs. For the full year, our operating expenses were $2.1 billion, up $107 million from 2021, primarily driven by acquisitions and investments into our video business. And the effective tax rate for '22 was 20% compared to 21% in the year prior, due to higher benefits from stock-based compensation in the current year.
Turning next to cash flow. Q4 operating cash flow was a record $1.3 billion, up $570 million compared with the prior year, and free cash flow was $1.2 billion, up $565 million from 2021. Our record cash flow performance during the quarter was driven by improved working capital and higher earnings. And for the full year, operating cash flow was $1.8 billion with free cash flow of $1.6 billion, consistent with the prior year.
Higher earnings in 2022 were offset by the cash payments related to the increase in annual incentive payments earned in 2021 and higher inventory. Capital allocation for 2022 included $1.2 billion for acquisitions, $836 million in share repurchases at an average price of $225 per share, and $530 million in cash dividends. Additionally, during the year we issued $600 million of new long-term debt and repaid $275 million of outstanding debt. We also increased our dividend to 11%, our 12th consecutive year of double-digit increases.
Moving next to our segment results. In Products and SI, strong demand continued with Q4 sales up 21%, including record revenue in both LMR and video. The currency headwinds were $43 million and revenue from acquisitions in the quarter was $20 million. Operating earnings in Q4 were $514 million or 28.4% of sales, up from 25.3% in the year prior, driven primarily by higher sales and operating leverage, partially offset by higher material costs. Some notable Q4 wins and achievements in this segment include several large APX NEXT device orders, including $45 million from the City of Houston, $39 million from a large US customer, $30 million from the City of Dallas, and a $21 million add-on order from a large US customer that previously purchased APX NEXT devices.
Additionally, during the quarter, we received a $20 million APX NEXT and Command Center order from Kansas City, a $19 million P25 System order for a large international customer, and a $3 million fixed order for metro rail in Chicago.
For the full year, Products and SI revenue was $5.7 billion, up 14% from the prior year, driven by higher sales of LMR and Video. Revenue from acquisitions was $53 million and currency headwinds were $98 million. Full-year operating earnings were $1.2 billion or 20.5% of sales, up from 19.4% in the year prior on higher sales and improved operating leverage, partially offset by higher material costs.
In Software and Services, Q4 revenue was 9% -- up 9%, which included $44 million of FX headwinds, and $19 million of revenue from acquisitions. Total software revenue was up 17% with double-digit growth in both Video and Command Center, while in LMR Services, revenue was up 5% after a $39 million FX headwind. Q4 operating earnings in the segment were $308 million or 34.4% of sales, down 100 basis points from last year, driven by unfavorable mix and higher acquisition expenses.
Some notable Q4 highlights in this segment include a $56 million P25 multi-year extension of the managed services operations at Interexport which serves the Chilean National Law Enforcement Police; a $25 million P25 software upgrade renewal for a large US customer; a $22 million next-generation 911 expansion, and renewal order for the Greater Harris County, Texas area; a $21 million system upgrade in multiyear services renewal for Lane County Oregon; a $15 million P25 and Command Center upgrade order for Columbus, Georgia; and a $15 million license plate recognition camera system expansion order from the Illinois State Police.
For the full year, revenue was $3.4 billion, up 8% on growth in Video, LMR services and Command Center. Revenue from acquisitions was $68 million and currency headwinds were $118 million. Full-year operating earnings were $1.2 billion or 35.3% of sales, down 110 basis points versus the prior year, driven by mix and higher acquisition expenses.
Looking at our regional results. North America in Q4, revenue was $1.9 billion, up 18% on strong growth in both segments and in all three technologies. For the full year, North America revenue was $6.4 billion, up 15% with double-digit growth in both segments and in all three technologies.
International Q4 revenue was $808 million, up 15% versus last year with growth in all three technologies. And for the full-year, International revenue was $2.7 billion, up 5% inclusive of the significant FX headwinds.
Moving to backlog. Ending backlog was a record $14.3 billion, up $788 million or 6% compared to last year, inclusive of $418 million of unfavorable FX and a $99 million reduction related to the exit of the ESN contract. The backlog growth was driven by the continued record demand we're seeing across all three technologies.
Sequentially, backlog was up $837 million, despite the record Q4 sales with growth in both segments. In the Products and SI segment, robust order demand in both LMR and Video continues to drive record backlog, which was up $894 million or 22% compared to last year. Sequentially, Products and SI backlog was up $68 million. This was our 10th consecutive quarter of sequential backlog growth in this segment.
In Software and Services, backlog was down $106 million compared to last year, which included $367 million of unfavorable FX, driven by Airwave and ESN revenue recognition, and the ESN exit, partially offset by strong growth in North America multi-year services, and software contracts. Sequentially, Software and Services backlog was up $769 million or 9%, driven by strong orders in North America and favorable FX adjustment from the prior quarter.
Turning now to our outlook. We expect Q1 sales to be up between 12% and 13%, with non-GAAP earnings per share between $2.02 and $2.07 per share. This assumes $40 million of FX headwinds, a weighted average share count of approximately $172 million shares, and an effective tax rate of approximately 23%.
For the full year, we expect sales between $9.65 billion and $9.7 billion and non-GAAP earnings per share between $11.10 and $11.22 per share. This assumes $40 million of FX headwinds, a weighted average share count of approximately $172 million shares and an effective tax rate between 23% and 24%.
We expect full-year opex to be up approximately $150 million versus last year, driven by acquisitions we've made, and our continued investments in Video. And we expect full-year operating cash flow of approximately $1.9 billion. And finally, the reason our effective tax rate is expected to be up 300 basis points to 400 basis points over last year is due to lower excess tax benefits on share-based compensation in 2023 and a higher UK tax rate that takes effect in April. We're also anticipating approximately $300 million of higher cash taxes compared to last year, inclusive of a one-time $75 million tax payment that relates to an IP reorganization we did in 2022.
And before I turn the call back to Greg, I wanted to update you on some strategic decisions we've made with respect to our PCR business. First, in order to further optimize our supply chain, we have moved the lowest part of PCR, which is sold to small businesses and some consumers to a licensed model with a third-party manufacturer. As a result of this change, we will only recognize revenues equal to the margin from the product.
In addition, we made a decision to exit some PCR markets in Asia. We expect these changes together to constitute an $80 million headwinds to our '22, '23 revenues, which is fully contemplated in our full-year revenue guidance for 2023. And finally, we enter the New Year with an even stronger balance sheet. We ended 2022 with $1.3 billion of cash and a net debt to adjusted EBITDA ratio of less than 2 times. In addition, our US pension is in a strong funding position with over 80% funded, reflecting the numerous actions we've implemented over the last several years.
We have also proactively refinanced our debt maturities with fixed-rate long-term debt and established a balanced maturity profile with an average duration of approximately eight years. All of this gives us the flexibility to continue to deliver on our capital allocation framework and be opportunistic in M&A.
I'll now turn the call back over to Greg.
