Thank you, Greg. Revenue for the quarter grew 12% and was above our guidance with double-digit growth in both segments, both regions and in all three technologies. FX headwinds during the quarter were $23 million, while acquisitions added $20 million. GAAP operating earnings were $518 million or 21.6% of sales, up from 16.7% and in the year ago quarter. Non-GAAP operating earnings were $641 million, up 29% from the year ago quarter and non-GAAP operating margin was 26.7%, up 350 basis points. The strong year-over-year increase in both GAAP and non-GAAP operating earnings was driven by higher sales, inclusive of our higher prices, pricing, lower direct material costs, and improved operating leverage.
GAAP earnings per share was $2.15 compared to $1.33 in the year ago quarter. Non-GAAP EPS was $2. 65, up 28% from $2. 07 last year. This strong growth in EPS was driven by higher sales and margins, partially offset by a higher effective tax rate in the current year. Opex in Q2 was $555 million, up $53 million versus last year, primarily due to increased expenses from acquisitions, investments in video, and higher employee-related incentives in the current year.
Turning to cash flow. Q2 operating cash flow was $93 million, up $83 million versus last year and free cash flow was $40 million, up $89 million. The increase in year-over-year cash flow was primarily driven by higher earnings and improved working capital, partially offset by higher cash taxes. For the full year, we continue to expect approximately $1.9 billion of operating cash flow. The linearity of our cash flow is expected to be consistent with last year with higher earnings and improved working capital driving increased cash flow in the second half.
Also, as we previously highlighted, this year's cash flow includes approximately $300 million of additional cash taxes compared to last year, inclusive of a one-time $70 million tax payment that relates to an IP reorganization that we did in 2022. Capital allocation in Q2 included $224 million in share repurchases, $148 million in cash dividends, and $53 million of capex.
Moving to segment results. In the Products and SI segment, sales were up 12% versus last year, driven by improved supply availability in the current year and the benefit from pricing actions continuing to flow through. Currency headwinds were $10 million and revenue from acquisitions in the quarter was $2 million.
Operating earnings were $285 million or 19.8% of sales, up from 14.6% in the prior year, driven by higher sales, lower material costs, inclusive of lower broker spend for semiconductors, and improved operating leverage. Some notable Q2 wins and achievements in this segment include $145 million P25 system upgrade for Kern County, California; a $41 million P25 system and device order for a US federal customer; a $31 million P25 system expansion for Ventura County, California; a $19 million P25 device order for a US federal customer; and a $6 million fixed video order for a large US health care customer.
In Software and Services, revenue was up 13%, including 20% growth in command center and 19% growth in video. Revenue from acquisitions was $18 million in the quarter, and FX headwinds were $13 million. Operating earnings in the segment were $356 million, up 15% versus last year and operating margins were 36.9%, up from 36.1% last year on higher sales and improved operating leverage, partially offset by higher costs from acquisitions.
Some notable Q2 highlights in this segment include a $34 million video order for the Virginia State Police, which included our largest in-car video order ever, a $15 million LMR services agreement with City of Baltimore, Maryland, a $13 million managed services agreement for LMR and a renewal in Latin America; a $12 million command center order for a US federal customer and an $8 million LMR service agreement with another US federal customer. Looking at regional results for the company, North America Q2 revenue was $1.6 billion, up 11% on strong growth in all three technologies. International Q2 revenue was $762 million, up 16% versus last year, driven by growth in LMR and video, partially offset by unfavorable FX.
Moving to our backlog, ending backlog was a Q2 record of $14.3 billion, up 6% or $856 million versus last year, driven by strong demand in all three technologies. Sequentially, backlog was up $211 million, driven by record Q2 orders in both segments. In the Products and SI segment, ending backlog was up $496 million or 11% year-over-year and up $100 million sequentially, driven primarily by strong LMR demand. In Software and Services, backlog was up $360 million compared to last year driven by strong demand for multiyear software and services contracts in North America, partially offset by revenue recognition for Airwave and the adjustment related to the ESN contract exit. Sequentially, backlog was up $111 million, driven by record Q2 orders in the segment.
Turning next to our outlook. We expect Q3 sales to be up approximately 6% with non-GAAP earnings per share between $2.99 and $3.04 per share. This assumes a weighted average diluted share count of approximately 172 million shares and an effective tax rate between 23% and 24%. For the full year, we are again increasing both our revenue and EPS guidance. We now expect revenue in the range of $9.875 billion to $9.9 billion, up from our prior range of $9.725 billion to $9.775 billion, and we expect non-GAAP earnings per share between $11.40 and $11.48 per share, up from our prior guidance of $1.21 to $1.29 per share. This full year outlook assumes $25 million of FX headwinds, a weighted average share count of approximately 172 million shares and an effective tax rate of 23% to 24%.
Before turning it back to Greg, I wanted to provide some color on a few financial topics. First, an update on the CMA and Airwave. As we've stated previously, we strongly disagree with the CMA's final decision. Earlier this week, the CMA issued its remedies order regarding implementation of their final decision effective on August 1st. This procedural next step does not change our position regarding the ongoing appeal process and our strong belief in our case. However, from an accounting perspective, beginning August 1st, we will now defer revenue for the amount above the remedies order price control until the appeals process has been completed. This deferral and resulting lower revenue from Airwave for the remainder of the year is fully incorporated into our increased revenue and earnings guidance for the year.
Second, earlier this week, Moody's upgraded our credit from Baa2 from Baa3. This higher credit rating underscores the strength of our balance sheet, including the strong liquidity position, our balanced debt maturity profile, significantly improved pension status, along with a track record of consistently growing earnings and cash flow. And finally, our increased guidance for the year highlights the strength of our business as we enter the second half. Our backlog is exceptionally strong, driven by robust customer demand. And based on our current pipeline and supply chain environment, we expect backlog to remain strong going forward.
Additionally, the expected lower semiconductors we articulated in February, the cost related to these semiconductors, coupled with the pricing adjustments in our own portfolio that were implemented in the second half of last year are driving the significant full year margin expansion of approximately 175 basis points that is implied in our increased guidance.
I'll now turn the call back to Greg. Thanks.
