Clifton Pemble
Director, President & Chief Executive Officer at Garmin
Thank you, Teri and good morning, everyone.
As reported earlier today, consolidated first quarter revenue came in at $1.15 billion which is down 2% from the prior year. Four of our 5 business segments posted double-digit revenue growth driven by new product introductions and solid demand trends which mostly offset an expected decline in outdoor. Gross margin improved to 56.9%, driven primarily by lower freight costs. We generated $197 million in operating income, down 14% from the prior year and operating margin came in at 17.2%. We feel positive about our first quarter results which are consistent with the expectations we communicated in February. As such, we are maintaining the full year guidance issued in February, calling for revenue of $5 billion and EPS of $5.15. It's important to remember that Q1 is typically the lowest seasonal quarter of our financial year and much of the year lies ahead of us. Our diversified business model offers many different paths to achieve our goals and we believe we are on track to do just that.
Before turning the call over to Doug, I'll provide highlights by segment and a summary of what we see ahead. Starting with fitness, returned to growth with revenue increasing 11% to $245 million, driven by strong demand for advanced wearables, especially running watches introduced during the past year. Gross and operating margins were 49% and 4%, respectively, resulting in improved year-over-year operating income of $11 million. During the quarter, we launched the Forerunner 265 and Forerunner 965 which combine advanced training metrics, recovery insights and everyday health stats with a vibrant sunlight readable AMOLED display that does not sacrifice battery life. Moving to outdoor. Revenue decreased 27% and to $329 million, primarily due to year-over-year declines in the adventure watch category as we passed the 1-year anniversary of the highly successful Phoenix 7 Epic and Instinct 2 launch.
Gross and operating margins were 62% and 23%, respectively, resulting in operating income of $77 million. Our adventure watches are known for the rugged dependability, long battery life and rich biosensing capabilities that enable their use in demanding applications. During the quarter, we announced that the Phoenix 7 will be worn on the upcoming Polaris Dawn Spacelight mission to provide insights into the impact of space travel on the human body. Also during the quarter, we launched new handheld devices with the introduction of the GPSMAP 67 series and eTrex SE. These versatile handhelds offer longer battery life, improved positional accuracy and global communication via inReach satellite technology. We recently announced the DRIVE 53 GPS navigator featuring a high-resolution capacity of touch screen display, a fresh new design and built-in traffic options to simplify the drive.
We also announced the zumo XT2, a rugged motorcycle navigator that's built for adventure, with a larger and brighter 6-inch sunlight readable display. We expected the first quarter of the year to be challenging in comparison to the outstanding performance of the prior year. We believe these trends will moderate as we introduce new products throughout the remainder of the year. Looking next to the aviation segment, revenue increased 22% to $214 million, with contributions from both OEM and aftermarket product categories. Gross and operating margins were strong at 72% and 27%, respectively, resulting in operating income of $58 million. During the quarter, we announced additional certifications for our GFC autopilots which expands our addressable market, bringing the performance and safety enhancing benefits of our flight control technology to more aircraft models.
We also recently attended the Embraer Suppliers Conference, where we were named best supplier in the categories of systems as well as services and support for our G3000 flight deck in the Phenom 100EV and 300E aircraft. In addition, we were named the best of the best supplier to the entire Embraer organization. We also received an Operational Excellence Award from Airbus Helicopters. These prestigious awards are an affirmation of our reliable performance during the supply chain crisis and reflect our strong commitment to providing the best products and outstanding service to our customers. I'm very proud of what our aviation team has accomplished and believe there is much more we can achieve in this market. We are pleased with how our aviation segment has performed so far this year.
The supply chain disruptions of the prior year appear to be mostly behind us, while demand for new aircraft and retrofit systems remains resilient. Marine segment delivered another quarter of impressive results with revenue increasing 10% to $279 million, primarily due to the timing of spring promotions. Gross and operating margins were 54% and 26%, respectively, resulting in operating income of $72 million. During the quarter, we expanded our strong lineup of chartplotters with the introduction of the ECHOMAP UHD2 series which are preloaded with premium Garmin Navionics-plus cartography and offer wireless data sharing of live sonar and navigation information with other chartplotters on the boat.
Also during the quarter, we were recognized as the leader in navigation and sonar categories by Best Marine Electronics and Technology and for the fifth consecutive year, received a 2023 Top Product award from Boating Industry Magazine. Moving finally to the Auto OEM segment. Revenue increased 11% to $81 million, primarily driven by increased shipments of domain controllers to BMW. Gross margin was 28% and we recorded an operating loss of $20 million driven by ongoing investments as new programs move into production. During the quarter, we began deliveries of domain controllers for the 2024 BMW X5 and X6 from our Olathe, Kansas facility which represents an important milestone in expanding our manufacturing capability to serve world-class automakers. We also expanded our footprint in the 2-wheel market with the launch of an entertainment system for additional models of Yamaha sport touring motorcycles.
That concludes my remarks. Next, Doug will walk you through additional details on our financial results. Doug?
