Good morning, everyone. We're pleased with the quarter, and a detailed description was provided in our shareholder letter released earlier in the day. I'd like to go over some highlights. We achieved over $61 million in gross billings. We had adjusted EBITDA of $2.5 million. I'd like to highlight the EBITDA would have been $7.1 billion, without the higher than normal warrant charges. I believe this is an indicator that our operating performance continues to improve as we scale. Few highlights for the quarter include, and this one really excites me.
Our first order for Fiat Chrysler for over 240 units, another validation of our value proposition for material handling in automotive applications. Today, we have BMW, Daimler, Honda, VW, GM and now Fiat Chrysler's customers.
European expansion continues leveraging some of our new channel partners with an order for nearly 100 units at the BMW Leipzig factory in Germany. This deal was part of a German funding activity and Plug Power product support app programs that were supported in the recent announcement. Three, the sales funnel for non-material handling applications for our ProGen engines and stacks are continuing.
We have many OEMs and integrators testing our systems and stacks. This includes a wide range of activities that we are pursuing. Including a variety of on-road and off-road applications, large-scale stationary projects and aerial projects.
We also, in the quarter, closed the supply agreement with United Hydrogen for liquid hydrogen, which will positively impact our gross margins in future quarters. Hydrogen and vertically integrating into generation with partners is a key part of our strategy.
Fourth quarter will be a record for Plug Power as we are on track to achieve $235 million to $245 million in revenue and breakeven adjusted EBITDA for the year, a major accomplishment for the company.
We have announced 2 of our major 4 announcements for the year: First one was deployment of 500 units with StreetScooter using our ProGen engine in Germany by DHL. StreetScooter is 100% owned by DHL.
Our global partnership with ENGIE. ENGIE has a global footprint across 70 nations. We've already closed an order with ENGIE in a new region for Plug Power worth over $6 million. This is a deal that would have never been identified without ENGIE.
We have another deal pending that should close this quarter. Announcement three, which will be for a new multisite customer will be announced this year. We're already working with them preparing 3 sites for early 2020. Announcement four, which will further extend our hydrogen strategy, supporting our 5-year plan that was rolled out in September at the Plug Power Symposium. At the symposium, Plug Power outlined their plans for the next 5 years. All the slides from the presentation can be found in our website.
To highlight a few items. Plug rolled out a $1 billion revenue plan by 2024, with a mix of $750 million of material handing, $200 million in on-road vehicles and $50 million in stationary power. The company is targeting in 2024, $200 million in EBITDA and $170 million in operating income. An aggressive plan, but with our broad offering capability as the only turnkey shop in the fuel cell space, we believe these targets are achievable. At the seminar, the logic for achieving these goals were clearly enunciated.
Paul and I are now pleased to take your questions.
