David A. Zapico
Chairman of the Board and Chief Executive Officer at AMETEK
Thank you, Kevin, and good morning, everyone. AMETEK delivered record results in the third quarter with stronger than expected sales growth and outstanding operational execution leading to earnings above our expectations.
Operationally, our businesses are performing exceptionally well and successfully offsetting inflation with price increases, resulting in an impressive margin expansion. We are also seeing continued strong and broad-based demand across our diversified niche markets leading to impressive organic order growth and a record backlog of $3.2 billion.
And this morning, we announced the acquisition of two excellent businesses, Navitar and RTDS Technologies, expanding our presence in high-end precision optics and in testing solutions for the electric power grid and renewable energy applications. I will provide more details on these acquisitions shortly. Given our results in the third quarter and outlook for the fourth quarter, we are again increasing our earnings guidance for the full year.
Now, let me turn to our third quarter results. Third quarter sales were a record $1.55 billion, up 8% over the same period in 2021. Organic sales were up 11%. Acquisitions added 1 point and foreign currency was an approximate 4 point headwind in the quarter. Demand also remains solid across our niche markets with organic orders growing 9% in the quarter, while book-to-bill was 1.07, our ninth consecutive quarter of positive book-to-bill. Backlog at quarter end was a record $3.2 billion, up approximately $1.4 billion from the end of 2020.
Operating income in the quarter was a record $385 million, a 14% increase over the third quarter of 2021, while operating margins were 24.8% in the quarter, up a robust 140 basis points from the prior year with strong margin expansion in each operating group. Our ability to drive meaningful margin expansion despite the inflationary environment reflects the differentiation of our technology solutions and our flexible operating model.
EBITDA in the quarter was also a record of $463 million, up 12% over the prior year, with EBITDA margins a record 29.8%. This outstanding performance led to a record of earnings of $1.45 per diluted share, up 15% versus the third quarter of 2021 and above our guidance range of $1.36 to $1.38.
Now, let me provide some additional details at the operating group level. First, the Electronic Instruments Group. The Electronic Instruments Group delivered excellent operating performance with continued strong and broad-based growth. Sales for our Electronic Instruments Group were $1.05 billion in the quarter, up 7% from the third quarter of last year. Organic sales were up 10% with a 1 point contribution from acquisitions being more than offset by an approximate 3 point foreign currency headwind.
Growth was again broad-based across our EIG businesses with particularly strong growth within our Rauland, TMC Precitech and Thermal Process Management businesses. Third quarter operating income was $272.7 million, up 11% versus the prior year and operating margins were 25.9% in the quarter, up 90 basis points from the prior year.
The performance of our Electromechanical Group in the quarter was exceptional, with excellent sales growth and record operating results. EMG's third quarter sales were a record $497.7 million, up 8% versus the prior year with organic sales growing 13% in the quarter and foreign currency at 4 point headwind.
Growth was very broad-based across all of our EMG businesses. EMG's operating income in the third quarter was a record $136.5 million, up 19% compared to the prior year period. EMG's third quarter operating margins were a record 27.4%, up an impressive 240 basis points versus the prior year.
Overall, our businesses delivered outstanding performance in the third quarter allowing us to manage an uncertain macro environment, meaningfully expand margins and drive earnings ahead of our expectations.
Now switching to our acquisition strategy. We are very pleased to announce the acquisition of two highly strategic businesses. Navitar and RTDS Technologies are both excellent businesses and highly strategic acquisitions for AMETEK, expanding our presence with -- in attractive secular growth markets. Now let me take a moment to provide additional color on both these acquisitions, starting with Navitar.
Navitar is a leading provider of optical solutions for critical applications across several markets, including medical and life sciences, research, machine vision and robotics, semiconductor and industrial automation. Their comprehensive suite of high precision custom optical solutions includes fully integrated imaging systems, sensors, cameras, optics and software. Navitar is an excellent strategic and complementary fit with our Zygo business unit as their technical capabilities around cameras and optical systems further expand Zygo's product offering. Additionally, Navitar is a high-growth business is well positioned to benefit from the growth in demand for precision optical solutions across attractive growth markets. Navitar was privately held and is based in Rochester, New York.
Now switching to RTDS Technologies. RTDS provides real-time digital simulation systems used by utilities and research and educational institutions and in the development and testing of the electric power grid and renewable energy applications. Their simulation solutions allow engineers to rapidly prototype, verify and test the performance of the electric grid, power instruments and networks in a close-looped system to help accelerate product development life cycles and decrease testing cost.
RTDS' simulation solutions are playing a key role in the modernization of the electric grid infrastructure as well as supporting secular growth drivers including renewable energy, distributed power generation and energy storage. The acquisition of RTDS broadens our Power Instruments business' testing and simulation capabilities while expanding our exposure to the renewable energy space. RTDS is privately held and based in Winnipeg, Canada.
We are very excited to welcome the Navitar and RTDS teams to the AMETEK family. We deployed approximately $430 million on these acquisitions, acquiring approximately $100 million in annual sales.
Over the past two years, we deployed more than $2.4 billion in capital and acquisitions and acquired eight businesses. Our acquisition pipeline remains solid. We have a strong balance sheet and significant financial capacity and look to remain active in deploying capital on strategic acquisitions. In addition to the recent acquisitions, we continue to focus on ensuring AMETEK is strategically positioned for a long-term sustainable growth.
Our businesses are driving broader adoption of our organic growth initiatives, including growth kaizens[phonetic], digitalization and new product development. This includes making strategic growth investments across our businesses to help support and accelerate growth. For all of 2022, we now expect to invest approximately $110 million in support of these growth initiatives.
We are seeing great results from these efforts over both the short term and long term. In the third quarter, sales from new products introduced over the last three years was 27%, a record level for our Vitality Index, reflecting the great work of our teams. These efforts have helped lead to double-digit organic sales growth in each of the past six quarters.
Now, turning to the outlook for the remainder of the year. While we remain cautious in the short term, given the dynamic macro environment, we are highly confident in the quality of our businesses and our ability to manage through these challenging times. Given our strong third quarter results and outlook for the balance of the year, we are again increasing our sales and earnings guidance.
For the full year, we now expect overall and organic sales to be up approximately 10% versus our prior guidance of up high single digits. Diluted earnings per share for the year are now expected to be in the range of $5.61 to $5.63, up 16% compared to 2021. This is an increase from our previous guidance range of $5.46 to $5.54 per diluted share. For the fourth quarter, overall sales are expected to be up mid-single digits compared to the same period last year, and fourth quarter earnings are expected to be in the range of $1.45 to $1.47 per diluted share, up 6% to 7% versus the prior year.
To summarize, AMETEK had another excellent quarter. We delivered record performance, strong orders and sales growth, robust margin expansion, increased our earnings guidance for the year and acquired two strategic businesses. The strength of the AMETEK growth model and our talented global workforce is evident in our results thus far this year and will continue to allow us to operate at a high level through challenging market conditions. We remain well positioned for continued long-term growth.
I will now turn it over to Bill Burke, who will cover some of the financial details of the quarter, then we will be glad to take your questions. Bill?
