Thanks, Randy. Good evening, everyone. Before we get into the financials, a quick reminder that our fiscal calendar in the fourth quarter contained an additional 53rd week, and we've normalized our performance for this where appropriate, consistent with our pre-release a few weeks ago. As you just heard, we saw continued sales improvement during the fourth quarter, delivering $157.5 million in total revenue, inclusive of $11.1 million due to the additional 53rd fiscal week and total revenue for the full year of $522.9 million. When compared to the third quarter and excluding the 53rd week, fourth quarter sales increased 12.3% sequentially, another solid continued step forward in our gradual recovery. Same-Shack sales in the fourth quarter declined 17.4% compared to the prior year, an improvement versus a decline of 31.7% in the third quarter. This improvement was driven primarily by an increase in traffic compared to the third quarter from a decline of 42% to 30% sequentially. Similar to prior years, in mid-December we took our annual menu price increase of approximately 2% on average across all company-operated Shacks. Suburban same-Shack sales improved from down 16% in the third quarter to nearly flat in the fourth quarter and exited the year with positive growth due to the continued recovery of in-Shack sales and strong digital channel performance. Urban same-Shack sales, although still underperforming suburban Shacks, also improved from down 43% in the third quarter to down 31% in the fourth. As of the end of the fourth quarter, our trailing 12-month average unit volume was $3 million, significantly impacted by the pandemic over the vast majority of the year. Average weekly sales were $62,000 in the fourth quarter, a 6.9% sequential increase and with typical seasonality during the fourth quarter, resulting in lower average weekly sales we were pleased to see the continued improvement of this trend. This seasonality beat continued in fiscal January, with a further increased to average weekly sales of $63,000, an improvement in same-Shack sales down just 5% and with our suburban Shacks delivering growth of 8% compared to last year. As Randy mentioned, February has been marked by extreme cold and snowstorms across the country, which resulted in approximately 134 operating days impacted by full and partial closures. Through the first 3 weeks of fiscal February, our average weekly sales was $60,000, with a same-Shack sales decline of 16% versus the same period last year. Despite the continued volatility of COVID on both traffic and dining capacity, until the recent winter weather impact, we were pleased with the underlying trends in the business. As we approach the 1-year mark in mid-March since the initial and extensive impact of COVID, we do, however, remain cautious about our near-term sales outlook, especially in our urban business. However, we're more optimistic as we look further out to a continued gradual recovery as vaccine distribution increases and as we enter spring and warmer weather. In terms of ongoing digital sales mix, this has stayed high at 64% of Shack sales in fiscal January and 63% in the first 3 weeks of fiscal February, above our fourth quarter mix of 59%, with delivery being the main contributors to this increase during the colder weather and additional dining room closures at the start of the year. Consistent with recent quarters, our own app and web channels continue to perform well. In 2021 through the first 3 weeks of fiscal February, sales in those channels were up nearly 300% versus the same period last year. Since mid-March last year, we've welcomed over 2 million new purchases on our app and web, representing important momentum and ongoing opportunity as we see higher levels of frequency in our digital guests within Shack and have the increasing ability to communicate with them in a much more targeted and personalized manner than other channels. Looking at our digital strength another way, when we annualize Q4 digital sales, they equate to a digital-only AUV of $1.9 million, an impressive number in terms of overall weight and clearly highlighting the importance of digital, both today and moving forward for our business. As we focus on the enhancement of our digital and broader guest experience, we've been working to incorporate delivery within our own Apple web channel. We piloted this capability in a handful of Shacks in late December, early January, and we've now extended this roll out to over 100 Shacks, with full nationwide rollout expected through the end of the second quarter. We're still in the early testing phase, but looking forward to the longer-term opportunity here as we target the migration of third-party delivery orders to our own channels, ensuring they're the most attractive for our guests and to maximize that sales opportunity within our own ecosystem. One piece of that strategy is in relation to pricing, and we're in the early stages of testing a 5% menu price uplift on all third-party delivery marketplaces. We see the ability to offer lower pricing in company-owned channels as a key marketing lever as we look to expand our reach, whilst higher prices across our third-party delivery partners will help offset some of the additional costs that come to the sales channel. It's too early to share any potential impact of this pricing increase, for what, of course, I'll update you as time goes on and we learn more. The performance of all of our digital channels and our increasing integration into new Shack designs is integral to our future sales growth. And initiatives like curbside with its strong adoption to date gives us confidence in this strategy. We're seeing nearly half our guests selecting curbside when given the option, with nearly 190,000 unique guests trying curbside since launch and average order values over 20% higher than in-Shack orders at those locations. Moving on to profitability. Shack-level operating margin was 16% in the fourth quarter and 14.1% for the full year. As we moved through the year, we continued to manage costs very closely while protecting areas targeted and maximizing safety, the guest experience and sales growth. As previously mentioned, the fourth quarter included a 53rd week, which primarily benefited the other operating expense and occupancy lines, due to their relative proportion of fixed costs. Food and paper costs in the fourth quarter were 30.1% of Shack sales, in line with the prior quarter and approximately 50 basis points higher than the same period last year. The year-on-year increase was driven by higher packaging costs due to COVID protocols. In the near term, we expect underlying commodity costs to remain relatively stable with packaging levels staying high due to digital mix. Labor costs in the fourth quarter were 30.3% of Shack sales, broadly in line with the prior quarter and included a year-end retention bonus program we put in place for our Shack teams. As a reminder of the bonus program, we gave each of our hourly team members an additional $250 to $400 year-end bonus, in addition to guaranteeing manager bonuses throughout the fourth quarter. These were part of a broader investment in our teams over the course of 2020, where, in total, we paid out close to $6 million between the onset of COVID and the end of the year through a variety of premium pay and bonus programs. We continue to be eternally grateful to each and every one of our team members and managers for their hard work, commitment and perseverance during these tough times. We created over 1,000 new jobs across the business last year, including increasing our home office employee count by nearly 20% to further support our growth over the coming years. We issued equity grants to our Shack general managers and implemented our first paid time-off voting program to encourage election participation. As part of our broader commitment to continue to increase the compensation opportunity of our team members, we increased starting wages in the majority of our Shacks from January this year. We're launching additional benefits this year also, including a dependent care flexible spending account, expanding the length and eligibility for parental leave and paying our teams up to 6 hours to get vaccinated as this opportunity becomes available to them. Our teams are our most critical asset and enabler for growth, and we are committed to continue to invest in their well-being and development. Looking out, we expect labor inflation in 2021 to be in the mid-single-digit range and may experience an efficiency in the short-term as we increase hiring and training of new team members to support the continued sales return. Other operating expenses remain elevated in the current environment and were 14.7% of Shack sales in the fourth quarter, a slight improvement of 10 basis points versus the prior quarter, driven primarily by the 53rd week, partially offset by increased delivery commissions. Other operating expenses increased by 240 basis points compared to the fourth quarter 2019, driven by higher delivery commissions partially offset by lower Shack maintenance expenses. And looking forward, we expect operating expenses to remain elevated in the near term due to a higher delivery mix, COVID-specific safety supplies for our team as well as the gradual return of certain other costs in preparation for the expected sales recovery. Occupancy costs in the fourth quarter were 8.9% of Shack sales, 150 basis points sequential improvement compared to the third quarter due in part to the benefit of the additional sales in the 53rd fiscal week, together with a $900,000 onetime rent adjustment related to the closure of our Penn Station Shack. Compared to the prior year, occupancy was 10 basis points lower in the fourth quarter 2020, again due to the favorable impact of the 53rd week and the Penn Station adjustment, nearly all of which was offset by sales deleverage. G&A expense in the fourth quarter was $19.1 million, a sequential increase as we scaled back up investments across the team in support of accelerated growth ahead. We expect to continue to increase G&A throughout this year as we ramp up our opening schedule, test a broad range of new formats, including our first drive-thru and continue to enhance our digital and data capabilities. At this stage in the year, we expect our total G&A spend for fiscal 2021 to be between $83 million and $86 million. Within this number, our equity-based compensation is expected to be around $9 million, with an additional $1 million in Shack-level labor, a step-up from 2020 as our performance share plan was adjusted following the unforeseen impact from COVID. Preopening expense in the fourth quarter was $2.8 million, a sizable increase compared to the third quarter, driven by 8 new Shack openings, with a robust development schedule for both 2021 and 2022, we'll see preopening expense increase accordingly, particularly in the back half of this year. On a per Shack basis, we continue to find ways to optimize preopening operations, especially in existing markets where we can achieve higher efficiencies across most cost categories. We expect fiscal 2021 preopening expense to be between $14 million and $15 million. Impairments and loss on disposals in the fourth quarter were $7.2 million, driven by a charge related to the early termination of our Penn Station Shack lease, combined with an impairment of our home office expansion space in New York, both of which were noncash charges. One of the many resulting impacts from the last year has been the acceleration of a more geographically dispersed workforce, which presented us with the opportunity to write down some of our home office space, and were correspondingly lower some of our rents-related G&A going forward over the period of the lease. We'll continue to maintain our headquarters in New York City, where the majority of our team members will be located. However, we fully embrace the opportunity for certain teams to be more widely situated across the country, particularly those in some of our back-office functions. On an adjusted pro forma basis, we had a net loss of $1.3 million or loss of $0.03 per fully exchanged and diluted share. Excluding the tax impact of stock-based compensation, our adjusted pro forma tax rate during the fourth quarter was 24.8% and 27.5% for the full year, in line with expectations. A full reconciliation of our tax rate can be found in the appendix of our supplemental materials. Given the uncertainty caused by the COVID-19 pandemic in terms of the timing of a full sales recovery and the resulting impact on our taxable income, we will not be issuing specific 2021 tax rate guidance at this time. However, in a normal operating environment, our adjusted pro forma tax rate, excluding the impact of stock-based compensation, is expected to be between 26% and 28%, in line with 2020 levels. Moving to balance sheet. Our cash and marketable securities balance at the end of the fourth quarter was $183.8 million. We continue to generate positive cash flow at an operational level, but we'll use cash through 2021 as we ramp up capital expenditures for new Shack construction as well as continued digital investments. Wrapping up, although we still have a long way to go in this recovery, and certainly the February winter storms didn't make life any easier, we're confident in our journey through this and beyond. We have an incredible opportunity for growth ahead, further strengthened by an expanding format strategy, a robust digital foundation and a passionate and talented world class team. We'll continue to invest with confidence against that opportunity, focused on the long-term as we build a business for generations to come. With that, I'll turn it back to you, Randy.
