Thanks, Andy, and good morning, everyone.
As you know, I recently completed my first year at Kimball Electronics. It's been a good journey already, and I am excited about the future for the company.
Before I get into our Q3 results, I want to share some observations on the business and provide an update on our strategic direction and structure moving forward.
Firstly, I mentioned early on that I was drawn to the Kimball opportunity for a number of reasons. But at the top of my list were the outstanding company culture and the opportunity to build on a strong foundation to achieve significant value creation. My experiences so far have confirmed those perspectives. We spent a great deal of time visiting our locations, meeting with customers and working with our leadership team to complete an in-depth review of our strategic focus, vertical market structure and organization design. Based on that review, we are announcing steps today to sharpen our strategic focus and to further position the company for profitable growth and stronger performance moving forward. Those steps which we have taken recently or are taking now include the following: first, divesting our automation, test and measurement business.
While this business has a bright future ahead, it is not a good strategic fit for Kimbell and our goals for future growth. The business models are not synergistic, and it is imperative that we focus on the growth opportunities in our core EMS business.
We are still an active customer of the AT&M business.
Next, increasing the focus and support for our core EMS business, including realigning our medical solutions business unit in Indianapolis into our EMS medical vertical for further differentiation. Consistent with these structural moves, we have elevated 2 key executives to enterprise-wide operations and commercial responsibility. Steve Corn as Chief Operating Officer; and Kathy Thompson as Chief Commercial Officer.
In addition, we are responding to this period of end market softness by controlling what we can control, including resizing our team, taking specific cost actions and continuing to focus on significant working capital improvements. We recorded impairment and restructuring charge in the third quarter to support some of these actions. Jana will provide additional detail in a few moments.
As we anticipated, the operating environment remained challenged for the EMS industry and our sales in the third quarter declined.
We expect the macro headwinds to persist in fiscal 2025.
During this period of end market softness, we are taking action by proactively aligning our cost structure with short-term demand trends, remaining competitive with stable operating margins and focusing on working capital improvements. Notably, inventory levels are now down over $90 million from the peak.
We continue to make investments in longer-term growth opportunities that are supported by a robust funnel of new business in the next 18 to 24 months, while deploying a capital allocation strategy that balances organic growth, lasting customer relationships and returning cash to share owners with opportunistic share repurchases. Net sales in the third quarter totaled $425 million, a 12% decrease from the prior year. The decline was shared across the 3 vertical markets we support with softness in each region of our global footprint. On a sequential basis, however, sales increased $4 million or nearly 1%, which is impressive given the 32% growth we experienced in the prior year quarter. We estimate on a 2-year stack basis, the growth in each of our verticals is in the low to mid-teens.
Although we are anticipating year-over-year declines next quarter, we do expect sequential growth over Q3. Net sales in the automotive vertical, our largest business, were $202 million, down 9% compared to Q3 last year and 47% of total company sales. The decrease this quarter was driven by continued weak demand in Europe, incremental softness in North America and a decline in China. When comparing Q3 sales to last quarter, North America and Europe both posted sequential increases.
We continue to believe the longer-term opportunity for growth in automotive will be driven by an increase in the rate at which electronic content is being added to vehicles, specifically in steering and braking systems. This content leverages advanced technologies and expanded operating systems that align very well with our core manufacturing capabilities and proven expertise in safety critical products, which ideally positions us for further advancements.
As we have stated numerous times, the architectures of the steering and braking systems are agnostic to vehicle titan, internal combustion engines, EVs or hybrids and that the automotive industry is highly regulated with stringent certifications, validation protocols and change management systems.
So this business is sticky and often results in program life cycles that can span 8 to 10 years in length with single source awards. Net sales in our medical vertical were $113 million, a 17% decrease compared to Q3 last year and 27% of total company sales. The decline this quarter was driven by lost sales with a major customer involved in an FDA recall, partially offset by growth with other customers.
As a reminder, our annual guidance assumes a net $50 million reduction in medical sales from this dynamic. That is a $100 million decrease in sales with the customer involved in the recall, partially offset by a $50 million increase in sales in new and existing programs. Similar to automotive, we continue to believe megatrends in the medical industry, including an aging population, increasing access and affordability to health care, decreasing medical device sizes, combined with the need for higher levels of precision, increasing connected drug delivery systems and the industry-wide trend of outsourcing higher-level assemblies will contribute to our longer-term top line growth.
We are strategically positioned to support technological advances in this vertical through Kimball Medical Solutions. Net sales in Industrial were $110 million, a 14% decrease compared to Q3 last year and 26% of total company sales.
As a reminder, results for the AT&M business are included in this vertical. In the third quarter, approximately half of the decline in sales in industrial resulted from year-over-year weakness in the AT&M business, with the balance driven by lower demand for internal climate control systems and smart meters in Europe, which as we reported last quarter, have been commoditizing. We frequently refer to industrial as green and clean with products that promote energy efficiency, safety, carbon neutrality and the better consumption of natural resources, including water, gas and electricity. We see the mega trend in legislation and incentives supporting the decarbonization as meaningful growth drivers, and we are strategically positioned to support products that reduce environmental impacts.
So a quarter filled with a number of important developments. I'll now turn the call over to Jana for her insights on the financial results and a review of our guidance. Jane?
