Chief Financial Officer at Zebra Technologies
Thank you, Bill. Let's start with the P&L on Slide 7. In Q2, net sales decreased 17.3%, including the impact of currency and acquisitions and were 16% lower on an organic basis. Our Asset Intelligence and Tracking segment was flat, strength in RFID and supplies was offset by a decline in printing as we lapped particularly strong prior year results. Enterprise Visibility & Mobility segment sales declined 23.6% and driven by a sharp decline in mobile computing, partially offset by growth in data capture solution.
Additionally, we drove organic growth across service and software with strong service attach rates. Sales declined across our regions, driven by broad-based double-digit declines in mobile computing. In North America, sales decreased to 11%. EMEA sales declined 24% with pronounced weakness in Eastern Europe. Asia Pacific sales decreased 17%, driven by China and India with growth in Japan and Australia. And Latin America sales decreased 6%, partially offset by growth in Brazil and Mexico.
Adjusted gross margin increased 200 basis points to 48%, primarily due to lower premium supply chain costs and favorable business mix and pricing, partially offset by expense deleveraging and unfavorable FX. We are pleased to see gross margins recovering from the inflationary headwinds we experienced over the past couple of years.
Note, that as we began to see demand soften, we announced incremental restructuring plans that are expected to drive $65 million of net annualized operating expense savings as they are implemented, including previous actions taken over the past year, our total net annual cost savings is $85 million. Second quarter adjusted EBITDA margin was 21.2%, a 70-basis-point decrease driven by operating expense deleveraging partially offset by improved gross margin. Non-GAAP diluted earnings per share was $3.29, a 29% year-over-year decrease. Increased interest expense contributed to the decline partially offset by fewer shares outstanding.
Turning now to the balance sheet and cash flow on Slide 8. For the first half of 2023, negative free cash flow of $144 million was unfavorable to the prior year period, primarily due to a greater use of net working capital due to higher cash taxes and payments for inventory. And $45 million of previously announced quarterly settlement payments, which are scheduled to conclude in Q1 of 2024, partially offset by lower incentive compensation payments. In the first half of 2023, we also made $52 million of share repurchases and invested $1 million in our venture portfolio. We ended the quarter at a 1.8 times net debt to adjusted EBITDA leverage ratio, which is below the top end of our target range of 2.5 times and had approximately $1.1 billion of capacity on our revolving credit facility.
On Slide 9, we highlight the impact of premium supply chain costs on our gross margin over the past 2.5 years. The actions we have taken to redesign products and increase price along with improving freight rates and capacity have enabled us to avoid component purchases on the spot market and reduce the freight cost impact. In Q2, we incurred premium supply chain costs of an incremental $5 million as compared to the pre-pandemic baseline. And $51 million lower than the prior year quarter. As we enter the third quarter, we believe these costs will have been fully mitigated, which is a key lever to margin recovery.
Let's now turn to our outlook. As we enter the third quarter, we are seeing sharp broad-based declines across most of our product offerings, which continue to be amplified by distributors recalibrating their inventory to lower demand trends. Our Q3 sales are expected to decline between 30% and 35% compared to the prior year. This outlook assumes double-digit declines across each of our core product categories, with distributor destocking accounting for approximately one-third of the decline. We anticipate Q3 adjusted EBITDA margin to be between 10% and 12%, driven by expense deleveraging from lower sales volume partially offset by higher gross margin from cycling $30 million of premium supply chain costs in the prior year period. Non-GAAP diluted EPS is expected to be in the range of $0.60 to $1.00.
Given our Q2 results and the continued challenging demand environment, we are significantly reducing our full year outlook, expecting a sales decline between 20% and 23%. This assumes that Q3 sales trajectory continues through the remainder of the year. We are seeing broad-based declines across our end markets as we enter the second half with significant uncertainty in this environment. We expect full year adjusted EBITDA margin of approximately 18%. We expect increased deleveraging on significantly reduced sales volumes expectations, partially offset by early benefits from cost reduction actions as most of the actions will be implemented by early Q4.
We plan to continue to align our cost structure with a long-term trajectory of our business. We now expect free cash flow to be positive in the second half. But negative for the year given lower sales and earnings expectations. Our cash flow will be impacted by new restructuring charges, increased cash taxes due to the change in R&D expected regulation and $180 million of previously announced settlement payments.
We continue to be focused on rightsizing inventory on our balance sheet as component lead times have normalized. However, we now expect minimal inventory reduction in 2023 due to our lowered sales outlook. We are focused on achieving 100% cash conversion over a cycle, which is one of the metrics in our long-term incentive compensation plan. Please reference additional modeling assumptions shown on Slide 10. Note that we have improved our expected 2023 non-GAAP tax rate by 1 point due to favorable geographic mix.
With that, I will turn the call back to Bill to discuss how we are advancing our Enterprise Asset Intelligence vision.
