Thanks Dave and good morning everyone. As Dave just discussed, our third quarter financial results included record third quarter total revenue driven by subscription revenue and AMS revenue. This performance reflects the ongoing resilience and growth generated by our business model resulting from strong execution across all five pillars of the strategic plan. As you've already seen, our continued strong financial and operational performance provides us with multiple capital allocation opportunities which we are already being pursued in parallel, given our very strong cash flows, reduced leverage and resulting firepower. This is evidenced by several recent announcements including our plans to accelerate share repurchases on an opportunistic basis and our previously announced 36% increase to our dividend, all while continuing to make investments in both traditional broadcast as well as OTT products and platforms. I'll further address, our future plans for capital allocation in more detail in just a few minutes. But first let's take a look at the drivers of our third quarter financial performance. As a reminder, my comments today are primarily focused on TEGNA's performance on a consolidated non-GAAP basis, to provide you with visibility into the financial drivers of our business trends as well as our operational results. You can find all of our reported data and prior period comparatives in our press release. For the third quarter, total company revenue was up 2% year-over-year in line with our previously announced guidance range. As a reminder, TEGNA achieved these historically high, third quarter results which were even stronger than the same quarter last year despite being up against $116 million of record political ad revenue last year. To provide you with additional color on our strong revenue performance during the quarter here are some details by category. Third quarter subscription revenue increased 16% year-over-year driven by subscription rate increases from renewals and contractual rate escalators in existing agreements. As a reminder, our multiyear network affiliation agreements, which encompass approximately 94% of our big four subscribers begin their next renewal cycle at the end of 2022, continuing through the beginning of 2024. As you've seen these renewals continue to provide a clear line of sight into the financial trajectory of these high-margin revenue streams. Third quarter record AMS revenue finished the quarter up 22% compared to third quarter of last year, driven by broad-based strength across nearly all advertising categories. Notably when compared to 2019 on a pro forma basis, third quarter AMS was up fully 12% despite the ongoing supply chain issues impacting the auto industry and other sectors. Third quarter AMS revenue did benefit from several Olympics though not significantly given both pandemic and time zone challenges. Excluding the estimated incremental impact of the Olympics, AMS was up fully 7% compared to 2019. Now to provide you with some additional color on how the key advertising categories performed this quarter. AMS showed gains across most categories, supported by strong advertising demand. All categories were up double digits over last year with the exception of automotive advertising. The strength in AMS above 2019 was broad-based, including services, health care, home improvement, sports betting, insurance, banking and finance, packaged goods and education categories. Beyond this, the advertising market continues to strengthen. With fourth quarter AMS also pacing significantly ahead of last year with all categories up again except auto year-over-year. More notably when compared to the fourth quarter of 2019, AMS is up as well. We expect these positive trends to continue, supporting strong and accelerating AMS revenue in the fourth quarter and into next year. Now turning to expenses for the third quarter. Non-GAAP operating expenses were $545 million, up 6% compared to the third quarter last year, driven by higher programming fees and Premion growth related expense. Excluding programming costs and Premion, non-GAAP operating expenses were up 2% when compared to the same quarter last year, driven by revenue growth. On a pro forma basis, operating expenses without the impact of programming and Premion were down 2% below 2019 level, reflecting the ongoing impacts of our efficiency, automation and expense reduction efforts. As a result, our third quarter adjusted EBITDA of $244 million was down just 6% year-over-year or approximately $15 million, driven by the absence of record $116 million high margin political revenue seen in the third quarter of 2020. Compared to the third quarter of 2019, adjusted EBITDA was up fully 56% driven by the growth in AMS revenue and net subscription profits, as well as the continued execution of thoughtful expense management. Adjusted EBITDA margin was 32% this quarter. Turning now to our balance sheet, which continues to benefit from disciplined expense management and thoughtful capital allocation decisions. As I mentioned earlier, now that we've achieved the debt reduction targets we established after closing our 2019 acquisitions, we have a number of additional tools to create ongoing shareholder value and a track record of doing just that through our organic and inorganic investments, dividends and share repurchases. TEGNA ended the quarter with total debt of $3.4 billion, producing net leverage of 3.39 times more than a full turn below last year, achieving our previous full year guidance of low three times by end of year, one quarter earlier than planned. We expect to end the year with net leverage of approximately 3.2 times. As a reminder, our only financial covenant is related to our $1.5 billion revolver. And we obviously have plenty of headroom under its 5.5 times leverage cap and do not have any debt maturities remaining for several years. Create further balance sheet efficiency and reduced interest expense, we plan to refinance the remaining $137 million of our 2024 notes at the beginning of December using funds available under the revolving credit facility. This will reduce interest expense by approximately $4 million in 2022 and is neutral to net leverage. Even with this draw, we continue to have plenty of capacity under our revolving credit facility, which provides us with significant financial flexibility. As of September 30th, there was more than $1.3 billion of unused borrowing capacity under our $1.5 billion revolver. As you've seen throughout our history, we continue to generate strong free cash flow, driven primarily by our high margin durable subscription and political revenue and the thoughtful management of our balance sheet. We achieved free cash flow of $137 million in the third quarter. As a result, we are not only reaffirming our 2020 to 2021 forecasted free cash flow as a percentage of revenue of 21.5% to 22%, but now fully expect to achieve the high end of that range. As Dave mentioned, earlier this year we meaningfully increased our return of capital to shareholders through a 36% increase in our quarterly dividend, which was already paid in July and again in October of this year. As a reminder, we also updated the expected timing of our opportunistic $300 million share repurchase program in September, which we will complete one year earlier subject to blackouts. As we've discussed before, we will continue to assess capital allocation options for the lens of maximizing value for our shareholders. This includes expanding our audience reach and services to support customers across all of our local station brands and platforms. To this end, we continue to evaluate all opportunities including organic and inorganic investments, quarterly dividends and share repurchases, all while continuing to reduce our leverage to target levels as we have done throughout our history. As you saw in our third quarter release, we provided guidance on key financial metrics for the fourth quarter and remain on track to meet or exceed our full year 2021 key guidance metrics. To help model other near-term expectations, we've also provided several fourth quarter financial guidance metrics in our press release including the following. For the fourth quarter, we expect total company revenue to be down year-over-year mid to high teens percent again, driven by the absence of $264 million political revenue, partially offset by continued growth in AMS and subscription revenue. We expect operating expense in the fourth quarter to increase in the low to mid-single digits percent range compared to fourth quarter 2020, driven by increased programming expenses associated with higher subscription revenue. Excluding programming costs, we expect fourth quarter operating expenses to be flat to down year-over-year. For full year 2021, we expect subscription revenue to be up mid to high-teens percent based on MVPD renewals completed at the end of 2020 as well as improving subscriber trends. As a reminder, we repriced approximately 35% of subscribers in the fourth quarter of 2020 and approximately 30% of the subscribers are up for renewal in the fourth quarter of this year. For full year 2021 EBITDA and free cash flow we will also continue to benefit from the more than $50 million of targeted annualized cost reduction initiatives that have been underway for the past 24 months with more to come in the quarters ahead as we continue to expand on these efficiencies. Turning now to an update on our key full year 2021 guidance elements. Corporate expense is expected to be in the range of $44 million to $48 million. Depreciation is projected to be in the range of $62 million to $66 million. Amortization is projected to be in the range of $60 million to $65 million. Interest expense is expected to be in the range of $187 million to $192 million. We expect capital expenditures to be in the range of $64 million to $69 million which includes non-recurring capital expenditures of approximately $20 million to $22 million. This is comprised mostly of UHF VHF transitions as well as the continuation of the centralization of our streaming facility. We continue to forecast an effective tax rate in the range of 24% to 25%. As I stated earlier, we've already achieved our year-end net leverage target of low three times and expect to close out the year at approximately 3.2 times. Finally, as I mentioned earlier, we expect to achieve the high-end of our 2020 to 2021 free cash flow range of 21.5% to 22%. Altogether, we expect both the fourth quarter and the full year to finish with the same strength and momentum as we've seen all year. I'll now turn the call back over to Dave for a few additional remarks before we take your questions.
