Thanks Paul. Good morning, everyone. I will focus my remarks on a few of the key financial results. The details of which are in the press release issued this morning and our 10-K that will be filed later today. Because we closed the Strongbridge acquisition in early October, the financial results I'm covering today, including fourth quarter and full year 2021 only include the fourth quarter impact from the Strongbridge acquisition. However, I will also be commenting on the full year proforma net product revenue results. As you heard Paul say, strong demand continued for Gvoke and Keveyis in 2021. On a pro forma basis, total net product revenue was $79 million for the full year, representing a 56% increase over pro forma 2020 revenues, finishing at the high end of the guidance we provided back in November. On a GAAP reported basis, fourth quarter total net product revenue was $21.4 million and for the full year was $49.3 million, reflecting only one quarter of Keveyis contribution. While we are not reporting net revenue by product, I will say that Keveyis did achieve the high end of our previous guidance range of $38 million to $40 million for the full year 2021. Gvoke continued its strong momentum in the fourth quarter, driving quarter-over-quarter prescription growth of 7% and topping 29,000 prescriptions, growing more than 85% from Q4 of 2020. For the full year 2021, Gvoke generated over 94,000 prescriptions representing 144% increase over full year 2020. As we move down the P&L cost of goods sold was $4.9 million for the three months ended December 31 2021, an increase of approximately $1.5 million compared to the same period in 2020. Cost of goods sold was $13.3 million for the full year ended December 31 2021, an increase of $4 million compared to the full year 2020, which included primarily product costs for increased product sales, partially offset by lower access and obsolete expenses. Turning our attention to expenses. Research and development expenses increased by approximately $5 million in the fourth quarter 2021 to $10.1 million compared to the same period in 2020. On a full year basis, research and development expenses increased by approximately $4.2 million in 2021 to $25.2 million compared to the full year 2020. These increases were primarily driven by higher pharmaceutical process development, and clinical costs across multiple programs. Selling general and administrative expenses increased by approximately $36 million in the fourth quarter of 2021 to approximately $54 million, compared to the same period in 2020. On a full year basis, SG&A expenses increased by approximately $52 million in 2021 to approximately $126 million compared to the full year 2020. Let me provide some important context to these increases relative to 2020. As I mentioned on our third quarter earnings call, given that the Strongbridge acquisition closed in early October, I communicated that we would incur a majority of the one-time costs associated with the transaction in the fourth quarter. I also mentioned that with the acquisition of Strongbridge, we would absorb the Keveyis commercial infrastructure which prior to the fourth quarter of 2021 did not exist in Xeris's financial results. This is important context in terms of the increases to SG&A relative to both the fourth quarter and full year 2020 results. With this context in mind, looking at the fourth quarter and full year 2021 increases, approximately $18 million and $24 million of the respective increases are related to the acquisition of Strongbridge, including transaction costs, restructuring related employee costs and insurance costs. These Strongbridge acquisition related expenses in SG&A, will not materially recur in 2022. Furthermore, these results do not include any impact from material cost savings synergies, the bulk of which we expect to realize by year end 2022. Additional drivers of the SG&A increase in the fourth quarter and full year 2021 include the previously communicated expansion of our Gvoke salesforce in 2021, the inclusion of the Keveyis commercial team and related expenses in Q4 of '21, and other commercial related expenses, including preparation for Recorlev launch in Q1 2022. These expenses accounted for approximately $16 million and $17 million of the fourth quarter and full year 2021 increase. To be clear, we believe that we are on track to realize $50 million in deal related synergies, approximately equally split between cost reductions and cost avoidance by the end of 2022. Additionally, our operating expenses going forward will include in the future costs for the launch of Recorlev, supporting the continued growth of both Gvoke and Keveyis and R&D and operating and other administrative costs associated with running a public company. Turning our attention to cash. As of December 31 2021, Xeris had total cash, cash equivalents and short term investments of $102.4 million, compared to $133.8 million at December 31 2020. We will continue to pay Strongbridge acquisition related costs in 2022, including severance and other accrued liabilities at year end 2021. Turning our attention to debt. As we announced earlier this morning, we entered into a senior secured term loan agreement with funds managed by Hayfin to provide us with up to a total of $150 million of capital. Under the terms of the debt facility, we drew $100 million on the closing date. And we repaid our previous debt facility of $43.5 million with Oxford finance and Silicon Valley Bank. The net proceeds will provide additional working capital to fund our business plan. An additional $50 million is available to Xeris at our election during the next 12-months. Based upon our current operating plan, we expect we will draw the remaining $50 million by the end of this year. We are very pleased to be partnering with Hayfin, his debt facility increases our financial strength and provides us with substantial resources by securing access to non-dilutive capital on attractive terms without over encumbering our balance sheet. Together with the recent equity financing, which closed in January Xeris has now added approximately $80 million of cash to the greater than $102 million of cash, cash equivalents and short term investments already on our balance sheet at year end 2021. This capital base and the additional $50 million from the debt facility provides the company with significant operating flexibility to drive our rapidly growing commercial business as currently constructed to cash flow breakeven by year end 2023 and thereafter produce increasing operating cash flow. As we look ahead, we project the rate of cash burn to improve over the course of 2022 as our revenue base continues to grow, and we see a decline in obligations associated with the Strongbridge acquisition related costs. With the revenue growth from our three marketed products combined with our current cash position, the cash received from the recent equity financing and the debt restructuring with Hayfin, we believe that we will finish 2022 with approximately $90 million to $110 million and further can achieve cash flow breakeven by year end 2023. To summarize, Gvoke and Keveyis had a great quarter and year in terms of net product sales. We have integrated Strongbridge quickly into Xeris and we'll achieve $50 million in synergies by the end of 2022. And we are in a solid position from a cash perspective to drive growth of Gvoke, Keveyis and Recorlev and fund our R&D pipeline. Let me turn the call back to Paul.
