Thanks Laurence and thank you all very much for joining us today. Mark and I pleased to be here to provide an update on our business and financial performance for the three months ended March 31st, 2019. Endava had another record quarter for Q3 fiscal year 2019 with revenue of £73.1 million, a strong growth of 24.7% year-on-year from £58.6 million in the same quarter in the prior fiscal year. Our revenue growth rate of constant currency was 23.2% year-on-year. This revenue growth is 100% organic. Since our acquisition of Velocity Partners was completed at the end of December 2017. Our revenue growth is strong and driven by the expansion of our existing customers and the acquisition of new ones during the quarter. We added 16 new clients during the quarter in all regions and verticals. We ended the quarter with 280 active clients, up from 271 at the end of December 2018 and 249 at the end of same quarter in the prior fiscal year. We continue to grow our largest client. We now have 67 clients who spent over £1 million on a rolling 12 months period, up 42 a year ago and 60 in the last quarter. Additionally, we continue to grow the number of large account. The number of clients spending over £5 million during the rolling 12 months period ended in March continues to grow strongly to 15 from 6 during the same period last year and 13 at the end of Q2 fiscal year 2019. We continue to expand in all three of our industry verticals and see acceleration in our newer verticals as we remain in the early innings for digital transformation and Endava is well-positioned to accelerate this revolution for our clients. We continue to make solid progress with our business in North America which grew 33.8% year-on-year 100% organic expanding in every vertical. North America accounted for 27% of revenue compared to 25% in the same quarter last year. On the technology side, we continue to see a pair of macro technology trends namely the move to cloud native architectures, as well as enterprises focusing on secure and streamlined paths to production for their software applications facilitating transformation initiatives. These trends combine to drive a strong interest in DevOps and in particular how to integrate security into DevOps practices. So called DevSecOps. Based on our project experience, we're developing reusable solutions to help some of our large clients develop capability in this area. In more technical work, the general awareness of and move to micro services and containerization continues to be of interest. Focus now moving to awareness of common difficulties, as well as just the benefits, which we see as a healthy development. Further, the overarching trend of organizations striving to effectively leverage data and analytics has led to many organizations being forced to revisit their understanding and governance of their data. As a result, we see many chief data officers setting up data ownership and governance frameworks within the business before looking for commercialization opportunities. In line with the desire to extract value from core data assets, organizations are also seeking new ways to better leverage their investments in internal knowledge and recognize the need to move beyond document repositories and search to create context and understanding from information. Building the next generation of knowledge management platforms, organizations can act automation, AI and key contributors to empower larger enterprise teams and enrich business value. Across these topics and along with many others, we are actively working to build and strengthen the technical communities in the cities where we work for our staff, the local communities and the clients. In the last 12 months, we have hosted 42 technical and digital community events. 13 of which are our high-impact Tech Flow events covering such subjects as quantum computing, experience fuel technologies and the digitization of humanity, applied machine learning and the demystification of DevOps. Now, today I'd like to highlight how our industry experienced, and offering of tech solutions is helping clients in one of our fastest growing verticals namely investment management. A rich heritage in this industry is solidified over the past five years into a significant part of the Endava business. Revenues from these clients grew on average by over 70% year-on-year over the past three years. Our clients are choosing us for our industry knowledge and our engineering quality. Prominent industry players including Jupiter Asset Management, Man Group and some of the industry's most important counterparties such as TP ICAP recognize our experience in field and the value-add we bring to technology delivery. Additionally, our partnership with AQR has grown over the last four years. Innovation and excellence in engineering is the cornerstone of the relationship. We're hoping to reduce costs and meet the needs of investors in an increasingly competitive market. We started work originally with Aberdeen Asset Management to build two core platforms that are now adopted as platforms of choice across the merged Aberdeen Standard Investments, with the entire industry battling fee pressure and budgets being continually squeezed. We implemented a cutting-edge cost-saving Azure cloud based architecture and have helped consolidate 120 corporate and investor websites onto one core next-generation platform, giving Aberdeen Standard Investment industry-leading fast to market distribution capabilities. We also helped realize the power of an organization's data estate. In an age of ever-increasing data volumes using the right information at the right time is a differentiator within the industry. And being able to access all the data within an established organization is a significant advantage. We felt one client achieve this by delivering a central services platform which serves up investor data from disparate data sources, provide a seamless unified investor experience. For quant driven investment management firms, we've been working on streamlining their data states, making insights more accessible to investment strategy decision-makers, whilst also reducing costs by implementing market data repositories, which eliminate the need for multiple purchases of the same market data set. We're building robust, faster market responses to regulatory change. We recently delivered solutions across the ever-increasing regulatory landscape. Many firms find it difficult to present the right data at the right time to meet new reporting standards. Our solutions have most recently helped a range of clients meet the challenge presented by the likes of PRIIPs and MiFID II regulation and comply with deadlines imposed by regulators. Our partnership with Bain & Company is progressing strongly bringing in two more active projects over the last quarter and successfully driving revenue growth for both businesses. We now have two clients who've registered over £1 million of revenue to Endava in the six months since we announced our partnership. The client undertaking the digital transformation strategic review that we mentioned on our last earnings call is one of those clients and is now moving into implementation with us. And a fortnight ago I and Endava team had the pleasure of attending the Bain Worldwide Partnership Conference in Hong Kong to brief the Bain Partners on progress and some of our joint success stories. This has resulted in an additional step up of relevant and exciting opportunities to pursue together with Bain & Company. Our client growth has translated into strong employee growth. We ended the quarter with 5,573 employees and 18.6% increase from 4,700 at the same point in the previous fiscal year. We remain an employer of choice in the cities where we operate. This month we won the Brand of the Year award in Romania. We also became a principal launch partner of the FinTech Alliance, a multi-faceted digital engagement platform that brings the global FinTech ecosystem together to explore, engage and do business. The FinTech alliance will be the first ever community driven platform for the FinTech industry providing a fully inclusive environment to support in tech growth. And finally an update on Brexit. We continue to review the potential impact of Brexit on Endava. Currently, we are not aware of any clients who are adjusting their spending plans with us as a result of the uncertainties caused by Brexit. Even with all the macro uncertainties, demand for our services remains strong and our pipeline is healthy in all geographies and verticals. We remain optimistic about our ability to deliver sustainable growth in the future. I'll now pass the call on to Mark Thurston, our CFO who will walk you through our financial results of the quarter and update guidance for the rest of our fiscal year.
