Thanks RJ and good afternoon, everyone. While our priority is across the business are focused on navigating through the uncertainty created by the coronavirus. I am pleased to report that our strong financial performance has continued and our liquidity position is strong. Following my overview of our fourth quarter performance, I will share our thoughts on where we stand today and our expectations for the remainder of the year. We were very pleased with the continued momentum we saw in the fourth quarter and the strength across all of our core financial metrics. Sales for the fourth quarter increased 12% to $655.5 million compared to the same period last year. This growth was the result of a 5.1% increase in comparable store sales, as well as the sales contribution from 31 net new stores open during fiscal 2019. We opened 10 new stores during the quarter with a balance of openings in mature and developing geographies. This was one more than we had anticipated as we were able to pull forward one of our plan 2020 openings into the fourth quarter. Fourth quarter gross profits increased 13.7% to $200.3 million compared to the fourth quarter of fiscal 2018. Our gross margin rate expanded 45 basis points to 30.6% in line with our expectations. Consistent with trends through the third quarter, this increase was a result of strong, opportunistic purchasing, as well as increased efficiencies and product delivery and inventory management. SG&A expense grew 19.3% to $167.9 million largely attributable to higher commissions resulting from gross margin dollar growth related to store expansion, strong and comparable store performance and gross margin rate improvement. Additionally SG&A increases were impacted by the adoption of ASC 842, the new lease accounting standard which moved approximately $3.2 million of previous amortization expense into non-cash rent. In addition to roughly $2 million of public company costs in the quarter. Stock based compensation expense for the fourth quarter was $5.6 million. Roughly two-thirds is related to the final year of investing for most time-based stock options under our 2014 equity plan, with the balance being recurring expense associated with stock options and restricted stock units granted at the IPO. Versus the fourth quarter last year, interest expense decreased 55.2% to $6.7 million as a result of our IPO related debt pay down and subsequent credit agreement repricing. Due to the tax benefit associated with employee option exercises during the quarter, we recorded a fourth quarter income tax rate of 4.6%. This drove the full-year effective tax rate down to 8.1%. GAAP net income for the quarter was $9.8 million or $0.11 per diluted share compared to a net loss of $4.6 million or $0.07 per diluted share in the prior year. For the quarter, adjusted EBITDA grew 5.6% to $41.5 million from $39.3 million last year. Excluding the impact of public company costs, adjusted EBITDA increased 10.7%. Adjusted net income increased 67.8% to $19.9 million or $0.21 per deleted share based on an average of 93.1 million diluted shares in the quarter. This compares to $11.9 million or $0.17 per diluted share on 68.5 million diluted shares in the prior year. Note that because fourth-quarter option exercises resulted in large benefits to our effective tax rate, we have presented adjusted net income based on our tax rate excluding discrete items. We believe that this more appropriately presents results as it reflects a normalized annual tax rate of approximately 28%. Turning to our balance sheet. As of year end, we had cash and cash equivalents of $28.1 million. Inventory was $219.4 million as compared to $198.3 million in a same period last year. For the year, we generated $132.8 million in operating cash and invested $97.2 million in gross CapEx. We were able to use excess cash generated by the business to make an additional $15 million debt prepayment in the fourth quarter resulting positive net cash flow for 2019 with $7 million. Regarding our capital structure, we ended the fourth quarter with $460 million in gross debt reflecting a 2.6x adjusted EBITDA net leverage ratio. Now let me discuss our expectations regarding the current year. As we are adapting to the current operating environment, our top priorities remain the safety of our customers and our Grocery Outlet community while continuing the critical work of giving product to the stores and on the shelves for our customers. While we can't say with certainty how the coronavirus will impact our business, let me share with you what we have seen to date. For the first eight weeks of the quarter, comp sales trends remain healthy consistent with our fourth quarter performance. Beginning in March, we saw customer demand both traffic and ticket begin to build in conjunction with concerns surrounding the coronavirus. As a result, comp sales increases have been significant across regions and as we've discussed the entire organizations working hard to satisfy customer demand. If less than one week remaining in our fiscal first quarter, we are currently standing at a quarter-to-date comp that is in the mid-teens. That said the operating environment is quite fluid and it's impossible to predict the magnitude and duration of the coronavirus impact, including if and for how long these elevated sales trends might continue as well as the potential impacts if demand normalizes. With this recent uptick in sales our cash and liquidity position is strengthened. In addition late last week purely as a precautionary measure in light of the current uncertainty in the global financial markets, we drew down $90 million from our revolving credit facility to further bolster our balance sheet. Combined with pre-existing cash, our current cash balance now stands at over $150 million. We feel extremely good about our liquidity position given that our credit facility does not mature until 2025 and it offers us broad flexibility provided our first lien net debt to adjusted EBITDA leverage ratio stays below 7x. Given the uncertainty surrounding the operating environment, we are not providing formal annual guidance at this time. However, we wanted to share with you how we're managing the business. With respect to comp sales, while we are currently operating at elevated levels, we continue to believe in our growth algorithm of a 1% to 3% comp range over the long term. With respect to unit growth so far in 2020, we will have 10 stores open by the end of this week and have approved sites and signed leases for 2020 openings consistent with our 10% annual unit growth target. That said we expect that our 2020 openings are likely to be negatively impacted like delays in acquiring permits and the availability construction resources given a growing mandate to shelter in place. Despite those potential near-term disruptions, we continue to search for new sites to build our longer-term real estate pipeline. With respect to gross margin, while we continue to expect stability and margin rates over the long term, we recognize that gross margin could experience short-term fluctuations for a variety of reasons. Regarding expenses, recall that our SG&A model are more variable in nature with both top-line and margin performance shared with operators via our commission structure. In addition, we plan to continue to invest in the business in pursuit of our long-term growth objectives. For these reasons, we expect SG&A to be stable as a percentage of sales over the long term. For 2020 specifically, we expect to incur approximately $9 million in public company costs compared to $4.5 million in 2019. We may also incur unplanned costs relating to the impact the coronavirus. With respect to adjusted EBITDA, we manage the business for stability and EBITDA margin rates over the long term. Moving further down the P&L. Inclusive of our recent revolver draw, annualized interest expense is expected to be slightly below $25 million based on current LIBOR rates. We continue to expect a normalized tax rate of approximately 28% which excludes discrete items. We expect weighted average diluted share account for the year to be approximately 100 million shares. This reflects the impact of 5.8 million performance-based stock options related to our 2014 equity plan of which 70% invested concurrent with our February 2020 secondary offering and will be reflected in our first quarter share account. As it relates to capital spending, we continue to prioritize our investments as follows. Number one, opening new stores consistent with our 10% annual unit growth target. Number two, reinvesting in existing fleet of stores and number three, investing in supply chain, IT and infrastructure to support growth. Over the long term, we expect a majority of CapEx spend will fund new store growth with a balanced supporting existing fleet and infrastructure reinvestment. As we learn more about the cadence of 2020 store openings, we will provide more color regarding their expectations surrounding the timing and amount of 2020 capital spend. In closing and what is proven to be a very volatile operating and financial environment, we continue to be pleased with the strength and durability of our business model, our cash flow generation and our liquidity position. But what's even more important is the incredible talent and dedication of our organization in a broader Grocery Outlet community. We can't thank them enough for everything they're doing to serve our customers during this challenging period. Before we begin Q&A, let me pass the call back to Eric.
