Thanks, Sam, and good morning, everyone. We appreciate you joining us for today's call. We're pleased to report another quarter of solid growth across the board. Jeff will go through the details in a few minutes. But I wanted to provide a few of the key financial highlights including total revenue of $282.7 million, a 32% increase over the second quarter of 2017. Net income of $22 million or $0.25 per diluted share versus $4.9 million or $0.06 per diluted share in the preceding period. Adjusted EBITDA of $47.8 million, which was 56% higher than the second quarter. Even more important, adjusted EBITDA margin increased by 250 basis points to 16.9% as compared to 14.4% in Q2.
Driving these impressive results was our unwavering focus on meeting the needs of our customers. As I've said in the past, we view our customers as partners in a business in which we are in for the long haul. Driven by attractive well economics with low breakeven prices, the Permian continues to benefit from robust frac demand that is outpacing available supply, and we expect that trend to continue through 2018. With 100% of our frac operations focused on the Permian and being headquartered in Midland, we are fortunate to not only enjoy exceptionally close relationships with our customers, but also understand the unique complexities of operating in the Permian.
We believe the keys to ProPetro's success are: providing a superior fleet, delivering best-in-class service to our customers, our commitment to our employees, their families and the community, and also ensure an unwavering commitment to safety. If we stay true to these principles, we will deliver a superior product to our customers. We believe this is critical as we recognize that if our customers are successful, we will continue to be successful as well.
Looking ahead, we anticipate continued evolution in the infrastructure and logistics in the Permian, especially as it relates to procuring West Texas and other sand sources closer to where our operations are located. Our internal cost structure and that of our customers should benefit from this dynamic heading into next year.
Supporting our long-term view of an improving environment, we deployed 3 new build frac fleets during Q3. In addition, in late October, we took delivery and immediately commenced operations of an additional new build fleet, bringing our current fleet capacity to 690,000 horsepower or 16 fleets. The acceleration of our new build capacity addition has been due to higher than anticipated customer demand for our services, along with the outstanding performance of our operations team and manufacturing partners. We have further responded by targeting deployment of an additional new build, 45,000 horsepower frac fleet, during the first quarter of 2018. Similar to the other delivered fleets that commenced operations recently, this fleet is committed under similar terms as our most recently deployed commitment with an industry-leading operator that we have worked with closely in the past. Combined with our attractive new build cost structure, this was a straightforward decision for the company.
I'm also excited to share that this will be the company's first dedicated fleet to work full time in the Delaware Basin, a region of the Permian where we see significant future opportunities to expand our business. We are also seeing increasing demand for other services beyond hydraulic fracturing. We constantly evaluate opportunities to further expansion in our nonfrac service offerings based on long-term market demand, expectations and internal capital allocation parameters.
I'm also happy to report that our plan to purchase an additional 86 Tier 2 engines by the end of next month is on schedule. 18 of these engines will be used in the manufacturing of the 17th fleet that will be deployed in the first quarter of 2018. These additional engines will provide us with the important flexibility as we continue to ensure the operational excellence of our current fleet and consider further expansion of our frac capacity. I would also note that by making this purchase now, we anticipate long-term cost savings of up to $30 million.
Also, we want to thank what I view as the finest group of employees and support contractors in the industry. Our continued success, as evidenced by our third quarter results, is a direct result of their tireless hard work and dedication, and we truly are blessed to have them on our team. This is not just my view, I hear this from our customers all the time. This steadfast focus on operational excellence and collaborating closely with our customers is a hallmark of ProPetro, and will continue to ensure our long-term success.
I will now turn it over to Jeff to discuss our Q3 financial results in more detail. Jeff?
