Flex opened fiscal 2027 with a strong first quarter, growing revenue 21% year over year to $7.9 billion and delivering record adjusted EPS of $1.00 (up 39%) with margin expansion across all three segments; GAAP operating income was $392 million (4.9% margin), GAAP net income $285 million, and GAAP EPS $0.76. The Cloud and Power Infrastructure (CPI) segment grew 35% to $2.2 billion on strong Power growth and ramping Cloud/Cooling programs (9.7% adjusted margin), Integrated Technology Solutions grew 20% to $3.1 billion on exceptional advanced-networking demand (offset by consumer weakness), and Regulated Manufacturing Solutions grew 12% to $2.7 billion with margin up 130 basis points on industrial strength. Flex was added to the S&P 500 and remains on track to spin off CPI as a standalone digital/electrical infrastructure company (SpinCo) via a tax-free spin in the first quarter of calendar 2027, framing AI increasingly as a power, cooling and grid challenge rather than just a compute story, and touting integrated power-cooling-compute IP (400V/800V, JetCool cooling, the NVIDIA modular platform, and expanded U.S. Cerebras manufacturing). The main negatives were cash and working capital: free cash flow was only $41 million (hurt by $24 million of one-time spin costs), inventory rose 24% year over year, and full-year free-cash-flow conversion guidance was cut to ~40% from 60% once spin costs are included, while CPI margins dipped slightly sequentially on ramp investment. Management raised/affirmed a strong full-year outlook - revenue of $33.7-35.2 billion (+23% at midpoint), adjusted operating margin of 7.0-7.2%, and adjusted EPS of $4.42-4.74 (+39%) - with CPI guided to 65-75% growth (back-half loaded, 90%+ booked for the next three quarters) and an ~80% FY2028 framework intact, positioning both future companies to capitalize on a multi-year AI-driven electrical build-out.

Good morning. Thank you, Michelle. In Q1, our teams delivered another exceptional quarter while continuing to prepare two industry-leading companies for the next phase of growth as standalone businesses. We delivered strong revenue growth, margin expansion across all three segments, and record-adjusted earnings per share of $1. Our Cloud and Power Infrastructure segment grew 35% year-over-year. As we stated before, our investments in this business are on track to drive accelerated growth and margin expansion in the second half of the fiscal year. We also saw strong growth in our communications and industrial business units driven by high-value markets such as networking, automation, and energy infrastructure. We are in the midst of a generational build-out driven by AI. Demand is not slowing down. We have built two focus companies to win in the AI era. These results reflect the strength of our strategy.
Our results also reflect our focus on long-term execution. Our addition to the S&P 500 last month reflects our progress over the last several years and the enduring strength of our strategy. We also continue to build momentum in some of our fastest-growing markets, expanding our partnership with Cerebras to scale manufacturing of the CS-3, one of the world's most advanced AI accelerator systems right here in the United States. We also launched a new liquid cooling solution through JetCool and showcased our next-generation power and infrastructure technologies at Computex. As we continue executing our long-term strategy for both Flex and SpinCo, I want to reiterate our vision for both companies. We have built two great businesses that are entering different phases of growth. The spin allows each company to sharpen its strategic focus, align capital allocation with its growth priorities, and create greater value for customers and shareholders.
SpinCo requires a capital allocation framework designed for rapid growth as demand for AI infrastructure accelerates. Many people still think about AI as a compute story. I think it's increasingly becoming an infrastructure story and more specifically, a power story. AI may live in the cloud, but the infrastructure behind it is very physical. It must be built, powered, cooled, integrated, and deployed at scale. As AI scales, the constraint is no longer just the chip. It's everything around the chip: power, cooling, electrical systems, and ultimately, the grid capacity. That's the challenge customers are trying to solve today. We saw this coming years ago, and that's why we invested in power compute and thermal management technologies long before AI became front-page news. What started inside Flex as a set of businesses supporting the next generation of data centers has evolved into a leading solutions provider.
I want to be very clear. SpinCo is not a data center components company. It's a digital and electrical infrastructure company built to help customers solve the power cooling and scaling challenges that come with AI. That's where we believe SpinCo is uniquely positioned to excel. We see our ability to bring together power, thermal management, and compute technologies, combined with the ability to deploy these capabilities at global scale as a true differentiator in this space. We have spent years working alongside the world's leading technology companies as they design, build, and expanded critical infrastructure. That combination of power expertise, systems integration, and execution is difficult to replicate. I would say we're still early. We believe we're at the beginning of one of the largest electrical transformations happening today. What's happening in the data centers is just the starting point.
As AI scales, demand will extend far beyond compute, driving investment across power systems, cooling technologies, electrical infrastructure, and ultimately, the grid itself. That's why we don't view this as a short-term investment cycle. The work required to power the next generation of AI will take years, creating ongoing opportunity across the broader electrical ecosystem with a very long tail. We are building SpinCo to lead that transformation. At the same time, Flex is exceptionally well-positioned to drive long-term value creation as a leading global manufacturing platform. Following the separation, Flex will remain a global manufacturing leader with a proven playbook and strategy, with deep customer relationships across diversified end markets and exposure to attractive long-term secular growth trends. These include healthcare, where an aging population and increasing prevalence of chronic disease are driving demand for medical devices and drug delivery solutions.
Robotics and warehouse automation, where regionalization and labor shortages support meaningful operations opportunities for continued growth. While SpinCo will focus on digital and electrical infrastructure, Flex will continue to benefit from pull-through demand in data centers, providing contract manufacturing services in the advanced networking and energy infrastructure markets. What remains underappreciated is the strength of the Flex portfolio and the related opportunity ahead. The same disciplined playbook that has driven our transformation over the last seven years will continue to guide Flex as it enters this next phase of growth. Ultimately, we are creating two distinct and focused leaders, each with the scale, strategy, and opportunity to succeed on its own.
Now turning to our transaction update on slide six, our dedicated separation management office and cross-functional teams continue to make tremendous progress towards the separation, and we are on track for tax-free spinoff in the first quarter of calendar 2027. Today, we're also pleased to announce additional leadership appointments for both SpinCo and Flex, effective upon completion of the separation. Thanks to the strong bench and depth of expertise we have built at Flex in recent years, we have strong leadership teams in place for both companies, ready to execute from day one, providing confidence, clarity, and continuity for our customers, employees, and shareholders. For more details on the extended leadership teams of each company, please refer to the press release we issued this morning. While it's certainly an exciting and dynamic time at Flex, we're executing from a position of strength.
Our teams are winning by delivering incredibly well for our customers and at the same time executing with discipline to deliver exceptional results. We're excited about what's ahead, and we look forward to sharing more in the months to come, including at our Investor Day on November 10th, where we will provide additional details on the path forward for both companies. With that, I'll turn the call over to Kevin, who will walk through the financials in more detail.
Thank you, Revathi, and good morning, everyone. I'm honored to be a part of this exciting journey and to work alongside both teams during this transformative period. It has been an incredible journey so far, and I'm energized about the opportunities in front of these businesses. I'll now review our results for the first quarter fiscal year 2027, which reflects strong execution as we continue preparing for the upcoming spin-off of our Cloud and Power Infrastructure segment. I'll start with our key financials on slide eight. First quarter revenue came in at $7.9 billion, up 21% year-over-year. Adjusted gross profit totaled $761 million, and adjusted gross margin improved to 9.6%, up 50 basis points from the prior year.
Adjusted operating profit was $534 million, up 35% year-over-year, with adjusted operating margins at 6.7%, up 70 basis points from the prior year, driven by business mix and underlying productivity improvements. Finally, adjusted earnings per share for the quarter increased to $1 per share, up 39% year-over-year. Turning to our quarterly segment results on the next slide, Regulated Manufacturing Solutions revenue were $2.7 billion, up 12% year-over-year, driven by strength in industrial. Adjusted operating income was $176 million, and adjusted operating margin was 6.6%, up 130 basis points year-over-year, driven by the aforementioned strong performance in industrial. Revenue from Integrated Technology Solutions segment totaled $3.1 billion, an increase of 20% year-over-year, driven by exceptional growth in communications.
Adjusted operating income was $158 million, and adjusted operating margin was 5.2%, up 10 basis points year-over-year, driven by the strong performance in communications and offset by weakness in consumer-related end markets. Finally, Cloud and Power Infrastructure revenue totaled $2.2 billion, up 35% from the prior year, driven by strong growth in Power as Cloud and Cooling continues to ramp new programs. Adjusted operating income was $214 million and adjusted operating margin was 9.7%, up 20 basis points year-over-year, driven by growth and margin expansion in Power. Moving to cash flow on slide 10. Free cash flow in the quarter was $41 million. Free cash flow was negatively impacted by one-time cash costs of $24 million, driven by activity related to the announced spin-off. Q1 inventory was up 10% sequentially and 24% year-over-year, largely driven by revenue growth.
Inventory net of working capital advances was 56 days, an increase of one day from the prior year. First quarter net CapEx totaled $235 million or approximately 3% of revenue. Turning to our updated outlook on slide 11. For fiscal year 2027, our expectations are the following. Revenue to be between $33.7 and $35.2 billion, up 23% at the midpoint. Adjusted operating margin to be between 7% and 7.2%, an increase of approximately 80 basis points year-over-year at the midpoint. We expect an adjusted tax rate of approximately 21%. We expect adjusted EPS to be between $4.42 and $4.74 a share, up 39% at the midpoint. Finally, we expect CapEx to be in the range of $1.5 billion-$1.6 billion. As a reminder, our prior guidance for free cash flow conversion of 60% excluded costs associated with the spin-off of our CPI segment.
Incorporating costs associated with the spin-off, we now expect free cash flow conversion to be approximately 40%. Moving to our updated fiscal year 2027 segment outlook. For RMS, we expect revenue to be up mid-single digits to high single digits due to continued strength in high-value end markets within industrial, including warehouse automation, robotics, and energy infrastructure. For ITS, we expect revenue to be up high single digits to low double digits, driven by continued strong performance in communications. For CPI, we expect revenue to be up 65%-75%, driven by both cloud and power, with power's growth rate exceeding cloud's. Finishing off with our guidance for the second quarter on slide 13. We expect RMS revenue to be up mid-single digits to high single digits on continued strength in industrial.
We expect ITS revenue to be up high single digits to low double digits on continued strength in communications, offset by weakness in consumer-related end markets. We expect CPI revenue to be up 45%-55% as new programs continue to ramp in both cloud and power. For Total Flex, we expect revenue in the range of $7.95 billion-$8.25 billion, up 19% at the midpoint, with adjusted operating income between $535 million and $565 million. Interest and other expense is estimated to be around $58 million, and the adjusted tax rate to be around 21%. Lastly, we anticipate adjusted EPS to be between $1 and $1.07 per share, up 32% at the midpoint based on approximately 375 million weighted average shares outstanding.
In summary, we are off to a strong start for fiscal year 2027, and we are well-positioned to deliver upon the commitments we made at the beginning of the year. With that, I'll now turn the call back over to the operator to begin Q&A.
