Thank you, Mike. Good afternoon, everyone. Thank you for joining us on the call today. Please turn to slide 3. We had a solid year in 2018 reaching several important public company milestones. Importantly, we remain on track to achieve our five year goals of $2.5 billion in revenue with 7% EBITDA margins. From a financial perspective, we had a strong end of the year with fourth quarter results that showed double digit year-over-year improvements in both revenue and adjusted diluted earnings per share. Additionally, expanded EBITDA margin 50 basis points year-over-year, all phasing in several new business wins. For the full year, we reached several milestones to the public company, with record revenue, operating margin and adjusted diluted earnings per share. With revenue for the full year increased 15% compared to 2017 and adjusted diluted earnings per share increased 35%. We continue to focus on expanding our margin profile and increased EBITDA margin by 30 basis points. I am especially pleased with our ability to expand EBITDA margin given our team's focus on phasing in approximately $350 million of new business that was won throughout 2018. A major positive financial attribute of Vectrus is our ability to generate strong, predictable cash flow. In 2018, our team continues to emphasis cash generation and grew net cash from operations 13% year-over-year which represents 114% cash conversion compared to net income. We ended 2018 in the strong financial position with $9 million in net debt, which will afford us the flexibility to execute our long-term strategy. We have spent considerable time establishing a solid foundation for Vectrus and strengthening our core. This is demonstrative in our portfolio diversification strategy which continues to show momentum in 2018 as our revenue with the Air Force increased almost 50% year-over-year. Additionally, the acquisition of SENTEL in 2018 provided access to new clients in the intelligence community. We are seeing solid traction with this new client and see significant opportunity for expansion of our core business. We are also successful in achieving geographic diversification and grew our revenue in the US and Europe by 60% year-over-year. In 2018, we initiated Enterprise Vectrus which is an enterprise wide program to combine our performance improvement initiatives under a single Enterprise wide management system. We've made great progress implementing Enterprise Vectrus in 2018 and successfully established a regional service center which leverages our global presence, enhances client support and lowers costs. We also have several other initiatives underway which we believe will improve client delivery, efficiency and create competitive differentiation. Regarding LOGCAP V, bids are submitted and award notifications are expected 12 April, 2019. Vectrus remained well positioned to win a seat on the contract vehicle and the CENTCOM area of responsibility or AOR. As a reminder, Vectrus is the largest service provider to the DoD and the CENTCOM AOR with incumbency on a major portion of the enduring CENTCOM workload expected under the LOGCAP V comp construct. It is also important to note that during 2018, we continue to solidify our position in the region through two additional new contract wins in Kuwait, Jordan and United Arab Emirates. We continue to believe that Vectrus winning the LOGCAP V CENTCOM area of responsibility to provide significant continuity and mission assurance to the DoD. On related note, we recently received our latest contractor performance assessment report from our army client on the K-BOSSS contract which will be incorporated as an enduring task order into the LOGCAP V competition. I'm proud to announce that we once again receive the highest possible ratings across all evaluated areas. Additionally, subsequent to the fourth quarter in January, we were notified by the US government of its intent to exercise an option to extend K-BOSSS until March of 2020 with an additional six-month option period through September of 2020. Our growth related activities have resulted in significant new business and expanded scope of existing work which is represented in the $1.4 billion of contract bookings in 2018. These awards resulted in a total backlog at your end of $3 billion. Our large backlog is another unique attribute of our business and provides significant visibility representing approximately 2.3x the midpoint of our 2019 revenue guidance. Please note that our total backlog does not include any value associated with the potential K-BOSSS extension past March of 2019. I'd like to thank our team of approximately 6,700 global employees for their execution in 2018 and our clients for their continued confidence in our business to support their missions. Please turn to Slide 4. I like to spend the next few minutes talking about our business strategy and opportunities. We have made great strides in executing our three core strategies of enhancing the foundation, expanding the portfolio and adding more value. And position Vectrus to grow and innovate in the emerging, converged, infrastructure market. We believe that the strength of our core capabilities combined with the emerging converge addressable market presents a significant opportunity to grow and to continue to transform Vectrus into a more diverse, more capable and higher value platform. During the year, we made significant progress enhancing the foundation of both our facilities and IT business to new wins, increase scope on existing contracts, the development and insertion of new solutions, as well as successfully integrating both clients and capabilities from our first acquisition. Expanding the portfolio with new clients, new capabilities and new solutions is transforming our business into a more balanced, higher value platform. On today's call, we address growth in our Air Force, Navy and intelligent community clients. The introduction and growth of our new technology enabled solutions and the growth of our pipeline by the execution of discrete, highly differentiated campaigns. In short, due to technological change in advancement and cost pressures, our clients are rapidly moving to integrated infrastructure solutions which we refer to as the converge market. The Vectrus strategy fully embraces has changed and we expect to lead with our clients to this exciting future. As we move to this converged future with our clients, we will continue to drive our strategic execution to adding more value. Whether we are adding more value as contract types move from cost type to fixed price or we insert technology into new or existing infrastructures or we move to more as service type offerings or we improve the performance of our core business and advisory processes, we will drive better value for our clients' mission and Vectrus' business performance. One quick final comment on the market. The federal market that Vectrus has historically operated in client purchase services and non integrated ways. Services like IT and facilities management are rarely purchased together. In the converged market, at facility and infrastructures are becoming IT enabled, digitized and sensor. Clients are purchasing and more integrated fashion, Vectrus continue to take steps to position for the buying behavior through solutions development and capability expansion. The net result of the transition is that Vectrus will have greater access to both traditional O&M funding in addition to an increasing spend on operational technology to be inserted into government infrastructures. Additionally, we will have access to adjacent international markets where large infrastructure related prime contractors, while looking for O&M providers with both operational and digital competency. Please turn to Slide 5. That can be seen from the results in portfolio composition on the right hand side of the slide, we have made substantial progress and strengthening the foundation of Vectrus and further building a unique platform that is a leading provider of facility and based operations, supply chain and logistics services, IT mission support and engineering and digital technology services to US federal government, primarily the DoD and the intelligence community. Our core competency in Vectrus is operating in global and all secured environments. Our geographic presence in 22 countries, as well as our capabilities is differentiated versus many competitors given the complex global operating and performance requirements. For example, in terms of competition in our primary markets we generally see a dozen or so viable competitors of varying sizes. Irrespective of size, we've been able to compete effectively against these competitors which are demonstrated in our new business wins. In 2018, our facilities and logistics services comprise 74% of total revenue and are aligned to strong and enduring funding sources. For reference, today the Department of Defense has 234 major active military installations that require an annual budget of over $25 billion for Operations Support. Additionally, these DoD facilities require sustainment, restoration and modernization programs, which have an annual budget in excess of $12 billion. Regarding the 26% of our revenues that come from our IT and network communication services, we focus on providing mission centric support. Our capabilities include agile software development, communications, network and cyber security, sensor integration and fusion, electromagnetic effects, spectrum management and border and perimeter surveillance. Today, we are also piloting the insertion of important new cognitive, robotics and artificial intelligence capabilities to improve the resiliency and reliability of our supported missions. Our core facilities and IT capabilities are differentiator and important to future growth at the traditional market for our services is changing as we migrate toward the converge market. This migration will require technology insertion which we are well on our way to doing. This technology insertion will be a key component of our future margin expansion, driven by a greater amount of fixed price contracts from which we can apply innovation and solutions. For example, in 2018 we won approximately $350 million of new business of which 60% is fixed priced in nature. As you can see from the pie chart in the middle of the slide five, this is a significant change from our current contract mix which consists of 22% fixed price type work. 2018, we made great progress expanding our client portfolio and footprint. As you can see from the pie chart on the bottom of slide five, approximately 27% of our revenue comes from clients outside of the army. Notably this is 11 percentage points higher from where we were in 2016 and now includes new clients such as the intelligence community. Finally, and as mentioned previously, we continue to make good progress diversifying our geographic presence with a 60% increase in both US, in European revenues over the prior year. Please turn to Slide 6. Over the past two years, we have made significant investments in growth and business development, which have resulted in higher win rates across the board and helped Vectrus to achieve client and contract diversification. We believe these investments as well as our internal initiative position Vectrus to execute on our new business pipeline in 2019. Our current new business pipeline is $9.1 billion and includes almost $8 billion of opportunities we plan to bid over the next 12 months, which is up from almost $7 billion of opportunities we had at this time last year. Additionally, we currently have $1.4. billion of bid submitted awaiting award. Just to reiterate, this is all new business to Vectrus. In total, with a larger pipeline and a quick and increased win rates, we see excellent opportunities to continue our growth path. On the top of slide 6, we highlight some of our new contracts that we won in 2018. Of note in September of 2018, Vectrus was awarded a position on the US Army's I Test 3s contract vehicle. And the multiple award IDIQ contract vehicles will enable the army to procure information technology services throughout the world. The I Test 3s contract replaces the predecessor contract I Test 2s and has $12.1 billion ceiling with a period of performance including options through September of 2027. Importantly, this is a contract vehicle that Vectrus who does not have in the past and we look forward to leveraging our strong IT capabilities which includes operating the largest overseas army cyber center to compete for task orders under this new vehicle. Please turn to Slide 7. As previously mentioned, our diversification strategy is yielding demonstrable results and is tied to Vectrus growth campaigns. Our campaigns lay out a deliberate approach to growth in a specific client center market by establishing differentiated value, strategic positioning, and tailored attack plan and a specific goal to build or take market share. In 2018, we continue to advance our US Air Force campaign which has resulted in an almost 50% revenue growth year-over-year with this important client. We are proud of our progress serving the Air Force client and notably our recent $84 million contract award to provide support services at Sheppard Air Force Base which builds on our Maxwell and Keesler Air Force Base contract wins. Now with almost a $0.5 billion worth of successful contract wins, Vectrus is a largest full and open based operation support services provider to the Air Education and Training Command. We have done a great job expanding our presence with the Air Force and we are currently a trusted provider of facilities and logistic services to the Air Force in nine countries. As you can see this targeted campaign has yielded positive results and we are currently executing a similar campaign with the US Navy. We are seeing early progress with our Navy campaign and in the fourth quarter were awarded a $60 million two-year task order to provide support services at Naval Station Guantanamo Bay. Importantly, subsequent to the fourth quarter, we were successful in winning our Navy fleet systems engineering team, RSF recompete which we have supported since the program's inception in 1999. This is $151 million task order under which we will continue to provide end-to-end engineering support for C4I systems to US Navy's afloat force. This recompete win in addition to our successful new business awards are examples of how we are applying innovation to our existing business and future opportunities through our offset program Vectrus management next-generation contract and Naval Station Guantanamo Bay win, Vectrus have been successful in expanding its Navy footprint, and we look forward to further growth and opportunity with this important client. Please turn to Slide 8. In 2018, we further implemented Enterprise Vectrus and are beginning to demonstrate improving performance and enhance margins. In aggregate, based our projects currently underway and other identified initiatives, we believe that over the course of our five-year strategic plan, Enterprise Vectrus will add approximately 80 basis points of EBITDA margin improvement to our 2018 level. Additionally, technology based solutions and client mix are a growing component of our portfolio and strategy to differentiate and achieve 7% EBITDA margin. In 2018, we introduced several solutions focused on energy management and operational technology solutions which include Argus, a Vectrus IT Mission Support solution that produce as aggregate sensor, video and map data on a single screen. This platform helps client close gaps in security operational efficiency and time management. Additionally, we successfully infuse commercial operational technologies to introduce process automation for work order management and rapid onboarding of system access on one of our key contracts. Finally, we made excellent progress in advancing our as a service or white-label and converged infrastructure capabilities. This includes Vectrus thermal coding which is a white label product, our water purification solution and power generation as a service. We will continue to advance our solution through in-house development, joint ventures and partnerships or through M&A. As you can see on the chart, we anticipate Vectrus solutions and client mix to drive a large portion of our margin improvement over time. Please turn to Slide 9, regarding LOGCAP V, Vectrus remains well positioned for an award and we are the largest service provider to the DoD in the CENTCOM AOR with incumbency on a major portion of the CENTCOM workload that is expected under LOGCAP V. Additionally, our client continues to score performance on this work at the highest possible levels. Our current K-BOSSS contract which are our largest program representing approximately 40% of our 2018 revenue will be a major portion of the enduring CENTCOM workload expected under LOGCAP V. As DoD potentially realigned its contingency operations overseas, which could include reduction in troop level in certain areas near and within CENTCOM, we believe there is a significant benefit to being the incumbent on the largest enduring army base in the AOR. 17 January, 2019, we were notified by the US government of its intent to exercise an option to extend our contract until March of 2020 with an additional six-month option through September of 2020. As a reminder LOGCAP V was an $82 billion ten-year IDIQ contract. They are expected to be up to six IDIQ contract awards; one award will be made to support each of the DoD six global combatant commands, while Afghanistan will be treated as its own area of responsibility. Retaining the K-BOSSS contract will require SEDAR LOGCAP V contract and winning The Associated CENTCOM AOR. Bids for LOGCAP V are currently under evaluation with awards expected on 12 of April, 2019. With approximately $900 million of annual revenue in the Middle East, Vectrus is a largest service provider in the region, and we believe that Vectrus award of the CENTCOM AOR would provide significant continuity and mission assurance to the DoD. Now I'd like to turn the call over to Matt who will go through our financial results.
