Itron posted second-quarter revenue of $607 million in line with expectations alongside record margins, profitability, and cash flow, including an all-time-high 36.9% gross margin and non-GAAP EPS of $1.62. The company lowered its full-year revenue midpoint by about 3% as customers and regulators slowed project deployments amid trade-policy uncertainty, with the slowdown concentrated in longer-term backlog rather than book-and-ship and no cancellations. Even so, Itron raised its full-year EPS midpoint by 13% on structural margin gains and reaffirmed its 2027 revenue and EBITDA targets.

Now please turn to page four of our presentation as our CEO Tom Deitrich begins his remarks.
Thank you, Paul. Good morning and thank you for joining our call. Itron delivered solid second quarter results despite ongoing macroeconomic and trade policy uncertainties. The team performed well, achieving revenue in line with expectations and earnings above. The outlook financial highlights for the second quarter are detailed on Slide 4 and include revenue of $607 million, adjusted EBITDA of $90 million, non-GAAP earnings per share of $1.62, and free cash flow of $91 million. Turning to Slide 5, Itron set new quarterly records for margins, profitability, and cash flow. This improved financial performance resulted from the continued execution of our strategy and the expansion of our customers' infrastructure. Our differentiated Outcomes segment continued to drive growth, reinforcing our market leadership in agile distribution infrastructure. During 2Q, demand for Itron's Grid Edge Intelligence platform remains strong.
By the end of the second quarter, we had shipped over 15.3 million distributed intelligence endpoints, up from 14.4 million at the end of Q1. The ongoing adoption of DI-capable technology underscores its importance for utilities seeking flexible infrastructure with real-time data capture and analytics. The long-term market outlook remains positive, driven by rising electricity demand, increased resiliency and reliability requirements, and ongoing focus on efficiency and safety. However, in the near term, customers and regulators face a more complex environment, leading to slower project deployments and delayed decisions in certain areas. Consequently, we are lowering our full year revenue outlook midpoint by approximately 3%. At the same time, growing customer demand for high-value solutions along with operational efficiencies has raised our full year EPS outlook midpoint by 13%.
Despite more deliberate customer and regulatory decision making in the short term, Itron continues to secure business from forward-looking customers adopting new solutions to address emerging challenges. Our second quarter bookings of $454 million are shown on Slide 6 and are primarily driven by our Network Solutions and Outcomes segments. As in recent years, we expect annual bookings to be weighted towards the second half of the year. We maintain our outlook for the full year book-to-bill ratio of one to one or higher.
Some of the key bookings for the.
Quarter include a large European utility. Greece's Hellenic Electricity Distribution Network Operator, or HEDNO, selected Itron to assist its efforts to enhance consumer experience, improve operational efficiency, and support Greece's goal of net zero emissions by 2050. Itron's solution will help HEDNO future proof its infrastructure and enable the adoption of grid edge intelligence platforms while establishing a strong operational foundation. Tucson, Arizona selected Itron for a large scale initiative that will support the city's critical water conservation goals. This network as a service deployment will enable the city to efficiently collect and manage water consumption data without the burden of maintaining additional infrastructure. Now Joan will provide details about our second quarter and our outlook for the third quarter and the full year.
Thank you, Tom. Please turn to Slide 7 for a summary of consolidated GAAP results. Second quarter revenue of $607 million was within the range we expected and slightly lower than the prior year, which included a significant amount of constrained revenue catch up. Gross margin of 36.9% is an all-time quarterly record and was 230 basis points higher than last year due to favorable mix. GAAP net income of $68 million, or $1.47 per diluted share, compares to $51 million, or $1.10 per share, in the prior year. The improvement was driven by higher levels of operating and interest income. Regarding non-GAAP metrics on Slide 8, non-GAAP operating income of $82 million was an all-time record and increased 19% year over year. Adjusted EBITDA of $90 million, or 14.8% of revenue, was also a new record and increased 16% year over year.
Non-GAAP net income for the quarter was $75 million, or $1.62 per diluted share, versus $1.21 a year ago. Q2 free cash flow of $91 million was a new record and compares to $45 million a year ago. This improvement reflects strong year over year operational earnings growth, higher interest income, and lower tax payments year over year. Revenue growth by business segment is on Slide 9. Device Solutions revenue decreased 8% on a constant currency basis, primarily due to the expected decline in legacy electric product sales, partially offset by continued growth in Water Network Solutions. Revenue decreased 1% year over year, primarily due to the non-recurrence of revenue catch up that occurred in Q2 of last year. Outcomes revenue increased 9% year over year due to continued growth of recurring revenue and software licenses.
Moving to the non-GAAP year over year EPS bridge on Slide 10, our Q2 non-GAAP EPS increased $0.41 year over year to $1.62 per diluted share. This was primarily driven by strong pre-tax operational performance, which contributed $0.39 year over year improvement. Turning to Slides 11 through 13, I'll review Q2 segment results. Compared with the prior year, Device Solutions revenue was $113 million with gross margin of 29.8% and operating margin of 22.6%. Gross margin increased 350 basis points year over year, and operating margin was up 260 basis points due to the favorable change in product mix. Network Solutions revenue was $409 million with gross margin of 38.5% and operating margin of 29.6%. Gross margin increased 160 basis points year over year, and operating margin was up 110 basis points due to improved products and customer mix outcomes. Revenue was $85 million.
Gross margin was 38.5% and operating margin was 18.4%. Gross margin increased 370 basis points year over year and operating margin was up 470 basis points due to a higher margin revenue mix. Turning to Slide 14, I'll review liquidity and debt. At the end of the second quarter, total debt was $1.265 billion and net debt was $41 million as of June 30th. Net leverage was 0.1 times and cash and equivalents were $1.2 billion. Now please turn to Slide 15 for our third quarter outlook. As Tom noted, our customers are becoming more deliberate in their decision making and slowing their activity levels in response to economic uncertainty, driven in part by the evolving trade policies.
Although our long term market expectations remain unchanged, we now anticipate a period of slower activity levels in the near term as our customers take time to assess the impact of emerging macroeconomic crosswinds on their business. Given this background, we now anticipate third quarter revenue to be between $570 million to $585 million. The midpoint of this range is down 6% versus Q3 of 2024. For non-GAAP earnings per share, we expect a range of $1.45 to $1.55 per diluted share. At the midpoint, this is a decrease of 18% versus Q3 of last year, which had an unusually low effective tax rate of just 4.5%. Normalized for a 25% effective tax rate, the midpoint of this range is up 4% versus Q3 of last year. Now please turn to Slide 16 for an update to our annual 2025 outlook.
We now anticipate 2025 full year revenue to be within a range of $2.35 billion to $2.4 billion versus the $2.4 billion to $2.5 billion range we provided in February. At the midpoint, this represents a 3% decline versus our initial full year outlook. It also represents a 3% decrease versus 2024, which had approximately $125 million of catch up revenue. Normalizing for the 2024 catch up revenue, the midpoint of our updated guidance is approximately 3% year over year growth. Our non-GAAP earnings per share full year outlook range is increasing versus prior estimates. Our current expectations for 2025 non-GAAP earnings per share is a range of $6 to $6.20 per diluted share versus our February outlook of $5.20 to $5.60 per share. At the midpoint, the updated non-GAAP earnings per share estimate is up 9% versus 2024 and 13% versus prior guidance.
We are proud of the work we have done to improve the margin profile of the business, which has allowed us to drive higher profitability on lower revenue. The revised full year guidance assumes a 22% effective tax rate. The actual tax rate could fluctuate based on jurisdictional mix and the timing of tax settlements. Clearly, there has been more uncertainty in the market environment than expected when we started this year. Our teams have and will continue to make the tactical adjustments necessary to support our customers' priorities as we maintain our long-term strategic course. Now I'll turn the call back to Tom.
Thank you, Joan. Our teams effectively managed macroeconomic and trade policies uncertainty in the second quarter, achieving expansion in both margins and free cash flow. Our intelligent connectivity and grid edge intelligence offerings continue to scale in line with our strategic objectives. Although customers and regulators have recently slowed their activity to address increased decision complexity and policy uncertainty alongside their existing operational priorities, the outlook for market growth remains strong. Itron remains confident in delivering value for stakeholders through disciplined capital allocation and sustainable returns. Thank you for joining our call today. Operator, please open the line for some.
