Thanks, Liz. Good afternoon, everyone. Before we start today's presentation, I'd like to acknowledge the service and support of our first chairperson, Chamath Palihapitiya. As announced last week, Chamath has stepped down as our chair and board member to focus on other public company board commitments. We've known the time would come when Chamath would move on to new initiatives, and I'm very pleased that long-term board member, Evan Lovell, who is the Chief Investment Officer of the Virgin Group, has agreed to serve as interim chair until the permanent chair has been named. Spencer Stuart has been retained to lead the search for a permanent chairperson, and they've already begun the process. I'd like to thank Chamath for his vision and groundbreaking work in transitioning Virgin Galactic to a public company, and also thank him for the support and insight that he's provided me over the past two years. Evan's deep experience with the company is a tremendous asset, and I'm excited to continue our excellent partnership as he steps into the interim chair role. Turning to slide four. 2021 was an incredibly important year for Virgin Galactic that laid an essential foundation towards becoming a scaled commercial operation. I'd like to call out a few highlights. We received approval from the FAA for our full commercial launch license, marking the first time that the agency licensed a company to fly customers to space. We successfully completed two crewed space flights that demonstrated the value of our product and our unique customer experience. The enormous media and consumer response to these flights reinforced our belief that demand for space travel will outstrip supply for the foreseeable future. We began enhancements to our current vehicles to ready them for commercial service, and we initiated the design work on the next generation of our space flight system that will become the backbone of our future fleet. Today, our focus is on scaling our business in a methodical way. With regard to our current ships and near-term schedules, we remain on track and on schedule to launch commercial operations in the Q4. Our vehicle enhancement program is progressing well, and is expected to be completed in the Q3. We've opened ticket sales to the general public and expect to have our first 1,000 Future Astronauts signed up by the time we launch commercial service. With regards to our future fleet and medium-term business plan, we've adjusted our design and manufacturing strategy to have our internal resources primarily focused on engineering, R&D, final assembly, and test. We will then leverage partnerships within the aerospace ecosystem to develop our major sub assemblies. We are putting into place the internal and supply chain infrastructure that will allow us to build our vehicles with high quality in a cost and time-efficient fashion. We've built out our senior leadership team, and we are continuing to attract and develop outstanding talent at all levels of the organization. All of these steps affirm confidence in our business model and our ability to generate attractive flight economics. Doug will share more detail about this later during the call. Turning to slide five and today's agenda. I'll start with an update on the readiness of our current fleet and then turn to our commercial plans, followed by an update on the manufacturing strategy for our future fleet. I'll then turn the call over to Doug, who will provide a financial update and some detail about our long-term economic model. Moving to slide six on our vehicle enhancement program. As I mentioned, we remain on track and on schedule to commence commercial service later this year. We are making excellent progress on the enhancements to our mothership Eve and our spaceship Unity. As we discussed last quarter, these modifications will meaningfully improve the durability, reliability, and predictability of these current ships and enable a higher frequency flight rate for commercial service. As we shared last quarter, Eve's enhancement program focuses on three areas: modifications to the center wing and launch pylon, replacing the horizontal stabilizers or H-Stabs located at the back of the vehicle, and completing upgrades to our avionics and mechanical systems, as well as strengthening various areas across the ship to reduce the volume of regular inspections. All of these modifications are designed to increase flight cadence as well as overall service life. These three work streams on Eve are complex and interdependent, and I'm pleased to share that all three are progressing towards completion in the Q3. The work we are doing on VSS Unity is also progressing well, and the ship is expected to be completed in the Q3. Unity's enhancements are designed to reduce maintenance needs by reinforcing and upgrading various joints and components located throughout the ship. As with Eve, the result of these efforts will be improved flight frequency, increased time between maintenance periods, and longer service life. Subject to testing and verification, we expect a monthly turnaround time for Unity. As a reminder, we anticipate that VSS Unity will begin flying revenue-generating flights in the Q4 later this year. We remain on track to begin Imagine's commercial service in the H1 of 2023. Flight testing is targeted to commence later this year, beginning with a captive carry flight. We will then move to glide flights and finally rocket-powered flights. We anticipate Imagine will begin conducting revenue-generating space flights in the Q1 of 2023, beginning with flying research payloads and then progressing to private astronaut flights alongside VSS Unity later in the year. We expect to see Unity flying monthly following its commercial launch, and we expect Imagine to fly twice per month once it finishes its flight test program. We are very excited at the prospect of delivering this level of capacity from our current ships. We are operating more efficiently, even as we absorb the continuing impacts of the pandemic and related labor disruptions. We implemented a COVID vaccine policy in Q4 of 2021 that required all employees to be fully vaccinated or have a legally entitled exemption. We are pleased that 94% of our workforce at the time complied with our policy, and all new hires are also required to be in compliance. This has helped the company minimize the impacts of the virus, although we have experienced elevated sick rates as a result of the Omicron variant. As an added step to mitigate disruptions from near-term labor shortages, we shifted certain non-critical work from the Q4 of 2021 into 2022. However, we do not expect these changes to impact the completion of our enhancement program or the launch of commercial service later this year. To date, we have not encountered any critical supply chain issues, but we are monitoring this carefully as we recognize that supply chains worldwide are under pressure. We are proactively planning ahead, assessing supplier health and ordering parts and materials further in advance to help mitigate potential raw material and labor availability issues. I'd like to extend a huge thanks to all of our teammates who have been working incredibly hard under pandemic-related protocols to deliver such great progress. Turning to slide seven. I am very pleased to share that Blair Rich has joined Virgin Galactic as our new President and Chief Business Officer for Commercial and Consumer Operations. In this newly created role, Blair will lead all aspects of our commercial strategy, including sales, marketing, business and product development, communications, operations, and customer experience. Blair brings a unique consumer-centric perspective to our company with an incredible blend of business, digital, and creative experience that she honed working with some of the most iconic brands in the entertainment industry. For the past year, she has served as a consultant and strategic advisor to Virgin Galactic, including guiding the marketing for the Unity 22 flight, which was viewed by tens of millions of people around the world. Blair will continue to play a critically important role in shaping our commercial strategy and enhancing our customer experience ahead of our commercial launch. With Blair's appointment, this rounds out our senior leadership team and ensures that we have deep expertise across all our key areas. Turning to slide eight. Last week, we launched our consumer brand and opened a limited number of space flight tickets to the general public, and we plan to have our first 1,000 customers signed up in advance of the launch of our commercial operations later this year. Given the robust response from our Spacefarers and early hand-raisers, we have approximately 250 seats remaining and demand through our direct sales channel is strong. As a reminder, we hold a $150,000 deposit against the total cost of $450,000, $25,000 of which is a non-refundable membership fee. Following the closure of our first 1,000 astronaut window, we will build a highly qualified reservation pipeline of future customers through a priority list with a $10,000 deposit required to join. We expect to leverage earned and digital media as well as word of mouth referrals from our ongoing flights to continuously supply the top of the funnel with new prospects, which we can then efficiently filter using our CRM tools and sales processes. Turning to slide nine and our Future Astronaut membership. Membership is included with ticket purchase, which adds additional appeal for customers and highlights our unique experience and service, distinguishing Virgin Galactic's offering in the industry. Future Astronaut community members enjoy access to money-can't-buy experiences, events, trips, and activities around the world, all delivered with trademark Virgin style. We provide opportunities to connect directly with the Virgin Galactic team, offering members deeper knowledge of our aerospace, flight, and engineering programs. Customers also gain exclusive access to Spaceport America, enjoy parabolic flights, centrifuge training, and VIP attendance at launches to name just a few of the benefits. Trips will include memorable opportunities like the inaugural Space for the Curious summit that we will be hosting later this year. A multi-day destination experience that's both intellectually engaging and entertaining. Past events have taken members to locations including Antarctica and Idaho to view the solar eclipse and the world-renowned Necker Island. This membership program builds engagement from the minute of purchase through the space flight, and we expect the high affinity that comes from these members to translate into repeat visitation, numerous referrals, and extensive lifetime customer value. Turning to slide 10 and the manufacturing strategy for our future fleet. While three human space flights per month from our current ships is an impressive task, we seek to open space to a much larger audience, and this requires a larger fleet capable of flying at much higher flight rates. In the past several months, we have spent a significant amount of time redesigning our manufacturing approach, and I'd like to outline how this will enable us to scale our operations and maximize efficiencies. Our current ships, Unity, Imagine, and Eve, have primarily been delivered in a fully in-house design, manufacturing, and assembly environment. This approach has been critical during our flight test phase, although it is a relatively slow and expensive process. As we step forward into higher rate commercial service, we will be augmenting our capabilities with strategically selected tier one suppliers to deliver major subassemblies in a cost and time-efficient manner. This is particularly important for our Delta class spaceship and next-generation mothership programs. Our approach takes advantage of the nationwide aerospace ecosystem to tap into talented preexisting pools of labor and optimize timing of capital expenditures. It also focuses our in-house expertise on design and engineering, final assembly, and fabrication of complex and critical parts that are all important elements of our intellectual property. Overall, we expect that this will provide us with a cost-effective and highly efficient manufacturing model for building out our Delta fleet and future motherships. As I mentioned on our last earnings call, we've established a new engineering design and corporate headquarters based in the strong aerospace corridor that runs from El Segundo to San Diego. This serves as our primary hub for R&D and the design of our new vehicles. We are currently focused on evolving the designs of our spaceship and mothership to enable greater flight cadence, as well as to support third-party supply of major subassemblies. It's an excellent location for innovation and collaboration, and we continue to ramp up engineering and support team talent at this location. We are also progressing designs and choice of locations for a new final assembly facility for our spaceships. We expect this final assembly facility to be operational in late 2023, and it will eventually employ hundreds of technicians and engineers with production capability of up to six spaceships a year. Similar to our approach with the Delta class spaceships, where we focus on the upfront design and engineering as well as final assembly, we are in the late stages of negotiation with preferred suppliers to manufacture the next generation of our motherships. We believe that leveraging strategic partners to build these major subassemblies will allow us to increase our speed to market and realize meaningful efficiencies without sacrificing quality or performance. Turning to slide 11, I will now turn the call over to Doug for an update on our financials. Thanks, Michael, and good afternoon, everyone. Before I review the financial results for the quarter and full year, I'd like to begin with a few comments on our broader financial strategy and economic model. We are making good progress in preparing our fleet and laying the groundwork for more efficient operations going forward. To help fund these initiatives, we raised $425 million through a convertible debt offering last month. We timed this capital raise to take advantage of the low interest rate environment ahead of expected rate increases. Furthermore, we entered a separate capped call transaction to effectively establish a 100% conversion premium. In other words, we have hedged our equity dilution risk up to a share price of $20.06. As of the end of January, we had approximately $1.3 billion of available liquidity, which represents the balance as of the end of the Q4, adjusted for the net proceeds from the capital raise. We are well-positioned for the investments we're making to drive the growth in the business. We continue to see significant demand for our space flight services. Our key objectives are to cost effectively expand our fleet and set ourselves up for long-run profitability. We will target investment to key areas to maximize shareholder value while also preserving capital along the way. We plan to invest upfront in NRE, our non-recurring engineering, to optimize our design of the Delta class ships for efficient manufacturing. This is a major leap forward for our manufacturing capability. Following our NRE investment, we expect that the subsequent ships will be produced in a repeatable, scalable fashion that drives a significant reduction in cost per vehicle relative to our current ships. What this means is that as our final assembly facility ramps up operations, we anticipate it will be capable of cost effectively producing up to six spaceships per year. We expect this will enable a rapid increase in flight capacity that will fully utilize Spaceport America and allow for fast expansion to additional spaceports. Our manufacturing strategy is also geared to leverage the well-established supply chain in the aerospace industry. As Michael mentioned, we plan to internally retain and build upon our IP in design and engineering, while also drawing upon tier one suppliers to provide major subassemblies. Virgin Galactic, in turn, will focus on final assembly and integration. This manufacturing approach streamlines our fleet ramp up by allowing us to rely on the best practices of existing supplier networks behind our direct suppliers. It will also reduce the total capital expenditure for infrastructure required to scale our fleet. Where possible, we plan to preserve our cash in the near term by deferring cash outflows to better match inflows. Examples of this include leasing versus building or buying, leveraging development incentives where accretive to our business model, and selective use of high-quality partners in the aerospace ecosystem to leverage preexisting workforce talent, infrastructure, and supply relationships. Turning to slide 12. Unlocking the economic potential of commercial spaceflight requires maximizing vehicle flight rate. As a reminder, following the completion of the current enhancement period, we expect to be able to fly our Unity spaceship on monthly intervals and our Imagine spaceship on two-week intervals. We plan to supercharge our flight rates with the introduction of Delta class ships, which we expect to be able to fly on one-week intervals. With support from the planning and design efforts that have been completed over the past few months, we are now able to provide more visibility into the economic model we are targeting. While we are not providing multi-year guidance, we want to share additional insights about our objectives as we scale the business. Based on our current schedules, we anticipate our Delta class ships could be ready to conduct revenue payload flights in late 2025 and progress into private astronaut flights in 2026. We are also planning to have next generation motherships available to pair with the Delta class spaceships as we scale the fleet. Our factory expansion plans are targeting production levels of up to six new spaceships per year. Taking into account the expected weekly flight cadence for the Delta class ships and the resulting growth in revenue from the expanding fleet, we are aiming for positive free cash flow by 2026. We have a range of options for the level of investment we choose to pursue. Given the strong demand we are seeing for spaceflights, combined with the prior investments in NRE, factory capacity, and other infrastructure, we foresee very favorable economics with the addition of each incremental spaceship to our fleet. Therefore, we expect to lean into the growth trajectory and continue with the expansion of our fleet and the potential addition of multiple spaceports. Our projected operating model reflects a low variable cost structure for individual flights. Our primary variable costs include operating expenses such as a rocket motor and other fuels, as well as lodging and training for the astronauts. Furthermore, we expect to realize economies of scale as we add multiple ships to our fleet because we anticipate that we will be able to spread our fixed costs over more ships and flights. Examples of our fixed costs are fleet maintenance, the flight crew, and rent. With the planned addition of Delta class ships to our fleet and the anticipated increase in utilization of the spaceport, adjusted EBITDA margins could be above 30%. Turning to slides 13 and 14, I'll now review our results for the Q4 and the full year. Free cash flow was negative $67 million compared to negative $74 million in the prior year period. This cash outflow was less than our previously shared guidance for the Q4. The lower spend was primarily attributable to labor efficiencies achieved during the quarter and by the shift in certain non-critical path work from the Q4 to 2022, both of which resulted in lower spending than previously forecast. As Michael noted, this shift of work and the associated spend is not expected to impact our timing to complete our enhancement program or the launch of commercial service later this year. The shift of work reflects enhanced planning, foresight, and contingency efforts from our team to ensure that we remain on track to deliver on time. Looking at the income statement, we generated revenue of $140,000 in the quarter, primarily driven by astronaut membership fees associated with new ticket sales. GAAP operating expenses for the Q4 totaled $81 million compared to $74 million in the prior year equivalent period. The increase in expenses was primarily due to higher employee costs and non-cash stock-based compensation expenses, as well as the opening of ticket sales. These increases were partially offset by a decrease in contract labor and material costs associated with the development of our spaceflight system. Total non-GAAP operating expenses were $65 million compared to $60 million in the prior year period. GAAP net loss for the Q4 was $81 million compared to a loss of $104 million in the Q4 of 2020. The reduction in net loss was attributable to there no longer being any outstanding warrants, as well as an increase in stock-based compensation expense. Adjusted EBITDA was -$65 million compared to -$60 million in the prior year period. Moving on to our financial results for the full year of 2021. We generated total annual revenue of $3.3 million. We received revenue from sponsorship and payload services associated with two spaceflights conducted during the year, as well as revenue earned from completion of certain technical milestones related to the Italian spaceflight agreement. As previously mentioned, we also received revenue for astronaut membership fees associated with new ticket sales. Net loss for fiscal year 2021 was $353 million compared to a $645 million net loss in fiscal year 2020. Adjusted EBITDA totaled -$245 million fiscal year 2021 compared to -$232 million for fiscal year 2020. Our balance sheet remains an area of strength for us. As of December 31st, 2021, we had cash equivalents, and marketable securities of approximately $931 million, which does not reflect our capital raise in January of this year. Looking ahead, a point to note about how we will be presenting some of our financial information going forward, beginning with the Q1 of 2022, we will no longer be providing gross margin on our GAAP income statement. Ultimately, the nature of our company is that of a service provider rather than that of a manufacturer. While we do manufacture our vehicles, unlike other aerospace companies, we do not offer our vehicles for sale as standalone products. Rather, we use the vehicles we produce to operate our spaceflight. As such, our revenue is derived from spaceflight services. Within GAAP guidance, in 2022, we are adopting the format of an income statement akin to that of major airlines, hospitality, and service companies. As I said earlier, given our differentiation as the first commercial spaceflight, our margin profile is expected to be much higher than typically seen in those industries. As for our guidance on spending for the Q1, we are completing the enhancement period on multiple vehicles concurrently while ramping the development work for our future fleet. We forecast free cash flow for the Q1 of 2022 to be in the range of negative $75 million-$85 million. We are confident that this work will provide real benefits to our flight rate and service life over the long term, while also optimizing for shareholder returns as we expand the fleet. I'd like to now hand the call back to Michael. Thanks, Doug. Turning to slide 15, I am very pleased with the progress we made during the Q4 and the full fiscal year 2021. 2022 is an important year for all of us at Virgin Galactic. Thanks to the dedication of our team, we are on track and on schedule to launch commercial service in the Q4, and we expect to be flying 3 times a month when Imagine joins Unity in passenger service in mid 2023. We are well on our way to signing up our first 1,000 astronauts before we launch commercial service, and we are scaling our business in an efficient and methodical way. Coming months will continue to be very busy for us, and I'm looking forward to sharing future updates on our progress. With that, we'll turn to questions. Operator, we are ready to begin the Q&A portion of the call. Thank you. If you would like to ask a question, please press star followed by one on your telephone keypad. If for any reason you would like to remove that question, please press star followed by two. Again, to ask a question, please press star one. As a reminder, if you're using a speakerphone, please remember to pick up your handset before asking your question. We will pause here briefly to allow questions to generate in queue. The first question is from the line of Oliver Chen with Cowen. Please proceed. Hi, Michael and Doug. Congrats on the opening sales. Michael, I would love your thoughts on the nature of demand that you've been seeing since you've opened the sales and how it informs, you know, your view of pricing, as well as, you know, thinking more broadly about friends and family and all the opportunities you may have ahead. Also, Michael, on the Commercial and Consumer Operations, I know you have new talent in that division. What are your thoughts about key priorities there and how they might work in conjunction with what you're doing in terms of Delta class and the scaling efforts you're making? Thanks a lot. Thanks, Oliver. The nature of the demand, you know, as we talked on the last quarter, we had a group of folks who kind of raised their hand earlier. We called them the Spacefarers, and there are around 1,000 people with a de minimis deposit that they put down. We had around 100 of those people, 100 of those 1,000, join. That brought us up to about 700 people. What we just announced this past week, the week that just passed, is we've now opened up sales of the remaining available slots within our first 1,000 Future Astronauts to the general public. This is the first time we've been really open up to the general public, you know, leveraging digital channels to do so. We picked up, plus or minus around 50 additional reservations, before we opened it up to the general public, some that carried in from the Spacefarers, some from some early hand-raisers. You asked, you know, kind of the nature of the demand. First, I'd say of the way we're processing our demand is by, you know, sharing what we do. The biggest thing was on that Unity 22 flight. That brings a lot of people into kind of our systems and allows us to engage in a conversation. It's a pretty wide group of audience. Some of them are going to be brand fans, some of them will be people aspiring to the future. Many of them are wanting to fly now. We use a series of customer journey communications to bring them into a group that really is high probability of wanting to fly right away. Then we use a one-on-one sales call around that. We have seen the majority of the seats were still seen as individual flyers, but we have seen sales across all the products we offer, individual flyers, couples, either friends or family together, as well as just a full ship purchase. Also, of course, we continue to focus on sales in our research piece. It's a good mix across the product mix. The other thing I'd say in the nature of the demand is these are people who, you know, pretty uniformly aren't looking at this as just kind of a quick transactional purchase. This is a life moment for them, and it's why we put so much effort into our kind of membership community. You know, you mentioned maybe shifting. Blair Rich joined as our President and Chief Business Officer for our commercial and consumer operations group. At the time when we are flying, part of that group's responsibilities will be actually handling of all the Future Astronaut and friends and family, managing the astronaut campus where people come. But up front, not only is this group managing the sales, but then immediately bringing people into this Future Astronaut community and engaging them. The consistent thing that we have found in these early calls are people recognizing the value of that. This is going to be something that is for their lives. They want to prepare thoughtfully for it, and that's also helped us kind of onboard people and quickly get them excited about the, you know, time period ahead, their flight and time after. Okay. A follow-up, Doug. The guidance is very helpful and creates cash flow of negative $75 million-$85 million in Q1. As we think about your strategically leveraging suppliers, how might the cash burn evolve in terms of that happening over time? Any puts and takes or thoughts longer term? Thank you. Sure. Thanks, Oliver. Yeah, so we guided for one quarter, and we didn't guide beyond that. I can tell you directionally that as we look at the work streams that will be coming in, where we are going through the NRE phase, the design, lining up the supply chain and the factory and so on, you would expect to see some increases in our spending as we build out the fleet, essentially. You know, the focus there, of course, is the fleet expansion because that's where we're gonna get the great returns on the business. That's our primary focus for the investment. We are leveraging the supply chain as you reiterated there. What that allows us to do is tap into their best practices, their processes, their suppliers, you know, behind them, and also minimize our capital investment. We pay them for the delivery of subassemblies rather than having to invest in the whole factory to do all the parts fabrication ourselves. That's the type of efficiency we can get by tapping into that supply chain, which helps our overall capital investment in a favorable way. Thank you. Best regards. Thanks, Oliver. Thanks. Thank you, Mr. Chen. The next question comes from the line of Kristine Liwag with Morgan Stanley. You may proceed. Okay. Good afternoon, guys. Michael, Doug, you know, following up on Oliver's question there on the free cash flow burn once you start investing in Delta, can you provide a little bit more color on that? How much will it cost? And then also can you provide more color regarding the maturity of the design for Delta and your negotiations with these tier one suppliers? Are they fixed, or is this still currently in the works? Sure, Kristine. Thanks for the question. This is Doug. I'll take the first one and then hand over to Michael. Regarding the cost, we're at a stage now, you know, with Delta where we're narrowing the list of suppliers for the subassemblies and working through that. You know, we're going through the process here, in terms of, defining that and basically entering the early stages of that process and negotiation process. At this stage, it's a little premature to be disclosing the cost per vehicle. I think you can understand our position where we're at in that life cycle. It wouldn't be in our best interest to put all of that out there. That's something we'll be able to share more on in the future as we narrow down you know the specifics with the supply chain. Michael, maybe you'd like to talk about the progression on the Delta. Sure. You know, we have two main parts of our program that we need to scale the fleet. The first is with our motherships that takes us through the first stage and then the Delta spaceship class itself. The motherships are quite advanced in the discussions that we've had. We don't have something to share today specifically, but I think in the not too far distant future we'll be coming back there. That's been I think a good set of conversations that reinforces the strategy. There are really quality people out there in the aerospace ecosystem that we can create value for them while also keeping the right things that we do ourselves, namely the design, getting everything set to put out major subassemblies, and then we'll do the kind of final assembly test, quality, safety piece. The mothership, I'd say, quite advanced in that dialogue there. The Delta class ships, we have been putting our investments and time. We've kind of moved through the basic trade spaces, we are now kind of getting into really refined requirements ahead of issuing the RFIs and the RFPs. We've narrowed our list of potential suppliers into a pool. We are well on the way to pick a location for where we will do our final assembly. We're not quite ready to announce that yet, but we've made great progress there. As you heard from Doug, we've been able to share some context on, while it's not appropriate to give multi-year guidance, we do want to share context on our internal planning horizons so people have kind of insight into our own goals and objectives that we're sharing with our teams. Kristine, I can add a little more too about the cost, the way to think about the cost. The approach we're taking here is we're investing in the NRE and the digital tools, and you'll often hear about this digital twin approach, which the leading aerospace companies will take. What this allows us to do with this more advanced modeling and digital tools is we have more predictable parts fabrication, you know, to tolerances, and then the easier manufacturing comes from that. That allows us to again invest upfront in that design, which leads to a cost-effective and repeatable you know manufacturing approach where we can create copies of this vehicle at a much lower cost than what we've been able to do before. The advancement in these tools and the modeling capability is really gonna help with that cost structure in the future versus how it used to be. Great. Thank you for all the color, guys. If I could do a one follow-up. I mean, you talked about the return to service of Unity, then Imagine, and you know, you're building the Delta class. Does this mean that, you know, Inspire is completely off the table, and, you know, it's not gonna be built at this point? Yeah. We're keeping it right where we were before. It's a good option value for us. We have the ability to finish it and complete it if we so choose. It also has potential use as part of the process to really go through and create a true production model vehicle. It has potential use in kind of a copper bird scenario as we're working through our avionics. It's also one that we can come back to. Right now our focus, as you can tell, is really accelerating our work on the Delta class vehicle itself. We haven't made the final choice on Inspire and just are keeping it kind of in our optionality base there. Our focus is clearly on pushing to the Deltas. Great. Thank you very much. Thanks, Kristine. Thank you, Ms. Liwag. The next question comes from the line of Myles Walton with UBS. Please go ahead. Thanks. Good afternoon, and thanks for the color on the fleet build-out. I was curious, as it relates to the 2026 positive cash flow, is the assumptions that you're at that stage still running CapEx pretty aggressively at the 6 per year build rate for the spaceships and then maybe one of the motherships and so your positive cash flow with that level of CapEx? Or is the idea that you're through the CapEx at that point? Thanks. Sure. I'll take that. Good question, Michael—Myles. So we actually have a range of options of how much to lean into that growth. But the scenarios all kind of point to the same general outcome, which is cash flow positive, you know, is the scenario we end up with here for the company in 2026, regardless of that number of ships. We can get there with a more moderate number of ships, or we can continue to invest and we still cross over because of the rapid increase in the revenue and the profits that come from that, which starts to, you know, far outweigh the ongoing investment. With that said, what we see is at that stage in our life cycle, because we've invested in all this NRE and the factory capacity and the space port and everything, there are real benefits to continuing to invest and leaning into that growth trajectory because the incremental profits from each added vehicle are really, you know, very attractive. The further we go, the further it moves us on that profit curve. You know, our likely case is to continue to lean into that and invest in additional fleet expansion. Okay. I would add. There's one other. You know, at that point. Oh, go ahead. I would also add, we'd be looking to the next space port too. That was the next question. In that trajectory, we would have. Yeah. I saw it coming. We would have, you know, the factory capacity ready to keep producing spaceships. We would like to leverage that and, you know, that would be kind of the, you know, after we populate the first space port, we'd be looking to continue that, those efficiencies and then populate the second space port and get the economies of scale on that second space port. Okay. I think you answered that one. The only other one I had was, for the first 1,000 Spacefarers, are you through that entire lot by the end of 2026 at this point based on your plan? Yeah. I'm sorry. Doug's looking at me, I'm looking at Doug. I believe we will. You know, we've probably given you enough data out there to track this. We do expect our current fleet will be flying three times a month as we get going and having Imagine come in in the H1 of 2023. That gives you kind of a sense of growth until we get our first Delta out. We think the first Delta, again, we're trying to have a balance here, Myles. You know, it's not appropriate to give guidance in multi-year phases in space flight program, but we also wanna share some of our internal planning. Yeah you know, objective horizon. We believe we are building our own kind of build-out and project plan to see the first Delta coming out with research flights, revenue-driving research flights at the end of 2025, moving into private astronauts in 2026. You can start to do some of that math on where the numbers will play. I would just flag that as you start to then bring in Deltas on a much more accelerated ramp-up, and again, with a weekly flight cadence and 6 seats per, we very quickly start to hit bigger numbers there. Anything that's not, I'd say, quite taken up by that 2026 period would be done very quickly thereafter. Okay. Thanks again. You're welcome. Thank you, Mr. Walton. Our next question comes from the line of Greg Konrad with Jefferies. Please go ahead. Good evening. Can you just maybe, you know, talk about the six a year production for Delta? You talked about that as a peak. You know, what's the timing of making that decision, and what kind of drives peak rate? How did maybe the economics of the spaceship change at six a year versus maybe a lower rate? Just to make sure I heard the question correctly, you're talking about the number of ships per year that we would use in our final assembly facility? Right. Exactly. Production of Delta. We definitely want to have kind of our supply chain and our final assembly plan able to handle that cadence. The reason is, as Doug mentioned, when we've invested the NRE up front, from what our plans show, we are going to have very attractive flight economics on a per vehicle basis. Scaling that is really strong, and the economics support that approach. Up to six is an interesting balance. It allows us to take, you know, the first year and a half of that and kind of finish out or top off Spaceport America from a fleet standpoint. Then that allows us to get to then a second spaceport. You know, you've got now, at the fast end, probably 1.5-2 years to top that one out, and then you could go to the next and the next spaceports. At some point you start to come back around, again to, just continue to update the fleets over time. Where we say up to 6, they're really easy break points of, you know, you can run at 4 if we would prefer or at 6, you know, just from a shifting standpoint there and still take great, kind of leverage off the tooling we've put in place and the lines we've put in place. It gives us the ability to pace a little bit with our demand. as we've, you know, continued to say so far, we feel demand is going to outstrip supply for quite a while. We don't need to overdo it. I think that gives us a solid pace. We definitely believe that the people who fly with us up front will want to fly in other locations and have word of mouth that will drive that. We also think it's important to go to other locations in the world. I just think that will bring in both heavier localized markets as well, but also variety. I just think we're going to build a great lifetime value with our existing customers who want to go and have different places they can see the world from space. This gives us good flexibility and I think allows us to just kind of pace that, as we see demand and as we choose to invest in the speed of growth. Then this might be pushing it a little bit too much, but I mean, appreciate the long-term business model. I mean, I think you talked about 30% EBITDA margins, free cash flow positive in 2026. I mean, as you ramp, is there any way to think about a conversion relative to EBITDA and maybe some of the offsets, whether it's working capital or CapEx and how we kind of think about EBITDA converting to free cash flow as you kind of get scale? I'm trying to make sure I understand your question when you talk about converting. Can you repeat the question? Just, you know, EBITDA converts at, you know, 50% free cash flow or 100% EBITDA to free cash flow conversion. Just trying to think about, you know, bridging EBITDA conversion, the 30% margin to maybe what the free cash flow potential is. Yeah, I think, you know, that question is related to the pace of growth, right? As we continue to move quickly into additional spaceports, obviously we'd use some of that free cash flow into the fleet itself. To the degree we choose to go a little slower in there, then you're going to see more flowing through and truly being free. I think it is, you know, as we said, it's premature to guide. We're not trying to guide here. We're trying to give some awareness into our kind of own internal planning. Probably, you know, as you said, probably too much of a stretch at this moment. I do think, as Doug said, we see really strong returns as we come out. We've made the investments in the non-recurring engineering. The demand remains strong. It will be a good kind of financial return, which is really where we look about how do we deploy our capital? What does that look like from a shareholder return basis? That feels like we will want to lean into that. I think, you know, we'll be trying to do so in a self-managed way by that point. I think there's a lot of opportunity and upside for us as we do. Thank you. Let me add regarding the timing of the EBITDA. When I was referring to EBITDA as, you know, potentially being over 30%, that's as we start to get utilization, good utilization of the spaceport. As you think about multiple Delta class spaceships, you know, populating Spaceport America, you're starting to get some good utilization going. It doesn't have to be fully utilized, but well utilized. You start to get that kind of scale going. That's when you get those, you know, the free cash flow being positive and the EBITDA approaching those percentages I talked about. Thank you. Thank you. Thank you, Mr. Konrad. There are no additional questions waiting at this time. That concludes the Virgin Galactic's Q4 and Full Year 2021 Earnings Conference Call. I hope you all enjoy the rest of your day. You may now disconnect your lines.
