Thanks, Anton, and good morning and afternoon to everyone. In my prepared remarks today, I will provide an overview of first quarter results, our outlook for the second quarter and updated guidance for full year 2022. In addition, I will briefly review our financial position and capital structure. I would also highlight our first quarter results press release, which includes a trailing 5-quarter analysis for the income statement, balance sheet and cash flows as well as various supplemental data. Additionally, we published an updated fleet status report yesterday and have begun disclosing individual contracts, day rates and other forms of compensation. We will continue to publish dayrate and other compensation information for all contracts and contract extensions on a go-forward basis, so long as our contract with the customer allows it. As Anton mentioned earlier, we are currently in a transitional period while we incur onetime reactivation costs to return 3 drillships and 1 semisubmersible to the active fleet. We anticipate that financial results will improve meaningfully as we complete these reactivations with these 4 contracts expected to contribute a combined annualized EBITDA of more than $100 million. Now that we are further along in the reactivation process of our 4 floaters, we estimate that reactivation costs will average $40 million to $45 million per rig, while future floater reactivations will likely be higher than that range. However, given the improving market and lack of available supply, we are now asking customers to reimburse a portion of the reactivation costs for future projects, which we expect will more than offset the increased reactivation costs. The floater market has improved significantly since these contracts were negotiated, and we are well positioned to benefit due to our 3 remaining uncontracted drillships, Valaris DS-7, DSA and DS-7. As Anton mentioned earlier, we are pursuing a number of attractive opportunities to reactivate at least one of these rigs, and we would expect these opportunities to pay back our reactivation costs within the first year of the contract. As a reminder, our reactivation cost estimates include all costs to reactivate the rig, but do not include mobilization costs or costs for contract or region-specific upgrades for which we would generally expect to be compensated. Most of these costs are recognized in our income statement with the remainder recognized as capital expenditures. As we have done previously, we have presented our results on both an EBITDA and EBITDAR basis as we believe reactivation expenses should be treated like growth capital expenditures with the income statement portion backed out of EBITDA when analyzing our results. Valaris' compelling value proposition is built on 4 key components, and we believe that it's important to value Valaris on a sum-of-the-parts basis. We have presented analysis in our press release broken out by these 4 components. First, our active fleet of 33 rigs, which includes rigs currently being reactivated, is generating positive cash flow today. Second, our leased and managed rigs comprised of 8 rigs we leased to ARO Drilling under bareboat charter agreements and 2 rigs that we manage on behalf of a customer in the U.S. Gulf of Mexico. Third, the stacked fleet, which includes many high-specification assets, which we have already demonstrated the ability to win work for and provide operational leverage to the continued improving market. And finally, ARO Drilling, our unconsolidated 50-50 joint venture with Saudi Aramco. Moving now to the first quarter results. Adjusted EBITDA in the first quarter was negative $31 million compared to positive $3 million in the prior quarter and adjusted EBITDAR, adding back onetime reactivation costs was $31 million compared to $40 million in the prior quarter. Revenues for the first quarter were $318 million compared to $306 million in the prior quarter. Excluding reimbursable items, revenues increased to $291 million from $283 million primarily due to higher utilization for the jackup fleet and higher average day rates for the Other segment, partially offset by lower utilization for the floater fleet. In the jackup segment, Valaris 249, 117, 114 in Norway, each commenced new contracts, either in the first quarter '22 or late in the fourth quarter of 2021. This was partially offset by idle time between contracts for Valaris Viking and 107. In the Other segment, revenues increased primarily due to higher day rates for managed rigs, Mad Dog and Thunder Horse, which were each awarded 2-year contract extensions with BP in the U.S. Gulf of Mexico, effective from late January. In the floater segment, revenues declined primarily due to Valaris DPS 5 being out of service for most of the first quarter, while undergoing a 5-year survey prior to starting the first of several new contracts. Contract drilling expense for the first quarter was $331 million compared to $286 million in the prior quarter. Excluding reimbursable items, contract drilling expense increased to $305 million from $264 million, primarily due to higher rig reactivation costs. which increased to $62 million in the first quarter from $37 million in the prior quarter as we prepare for floaters for long-term contracts that are expected to commence in the second quarter. First quarter reactivation costs were higher than our prior guidance. During the first quarter, we incurred approximately $4 million of additional costs related to an incident involving Valaris DS-16, which broke free from its mornings during gale-force winds causing minor damage to the rig. The remaining variance represents higher than estimated costs across the 4 reactivation projects, primarily due to additional identified work scopes that were not included in the original reactivation budgets. Aside from reactivation costs, the sequential quarter increase in contract drilling expense was primarily due to an increase in personnel costs and higher repairs and maintenance spend during DPS-5 special survey. Moving to our store base costs. General and administrative expense increased marginally to $19 million from $18 million in the prior quarter and onshore support costs which are included within contract drilling expense in the income statement, also increased slightly to $29 million from $28 million. The sum of these 2 categories provides our total onshore support costs which increased to $48 million in the first quarter from $46 million in the prior quarter. Depreciation expense decreased to $23 million from $25 million in the prior quarter. Other income decreased to $9 million in the first quarter from $21 million in the prior quarter. First quarter other income included a $2 million gain on sale of assets related to the sale of jackup Valaris 67 and compared to a $21 million gain on sale of assets related to the sale of jackups, Valaris 22, 37 and 142 in the prior quarter. The remaining other income variance is primarily due to lower reorganization-related professional fees in the first quarter as compared to the prior quarter. Tax benefit decreased to $1 million in the first quarter from $31 million in the fourth quarter. The first quarter tax provision included $15 million of discrete tax benefits primarily related to a reduction in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. The prior quarter tax provision included $30 million of discrete tax benefits, primarily related to a reduction in liabilities for unrecognized tax benefits associated with tax position taken in prior years and deferred tax benefits associated with the Swiss tax reform. Adjusted for discrete items, tax expense of $13 million in the first quarter compared with a tax benefit of $1 million in the prior quarter. The increase in tax expense is primarily due to our jurisdictional mix of earnings and a reduction in the deferred tax valuation allowances in the prior quarter. Of note, we still expect to receive a tax refund of $97 million related to the CARES Act, though the timing of this receipt remains uncertain. Moving now to our second quarter 2022 outlook. We expect total revenues will be in the range of $355 million to $370 million as compared to $318 million in the first quarter. Second quarter revenues are anticipated to benefit from each of the 4 reactivated floaters commencing contracts during the second quarter. Valaris DPS-1 started its contract with Woodside offshore Australia in late April. DS-16 is expected to start its contract with Oxy in the U.S. Gulf of Mexico in the coming days, and we anticipate that both DS-4 and DS-9 will start their respective contracts with Petrobras offshore Brazil and Exxon offshore Angola by the middle of the year. Also, Valaris DPS-5 started a new contract with Kosmos in the U.S. Gulf in late March after completing its 5-year special survey. As a result of these contract startups, operating days for the floater fleet are expected to increase by approximately 45% on a sequential quarter basis and are anticipated to increase further as we experienced the full quarter impact of these new contracts in the third quarter and beyond. We anticipate that second quarter contract drilling expense will be in the range of $315 million to $325 million as compared to $331 million in the first quarter, including approximately $31 million of onshore support costs. The expected sequential quarter decrease is primarily driven by lower reactivation costs, which are anticipated to decline in the second quarter as our 4 floater reactivation projects wind down and these rigs go back to work. Lower reactivation costs are expected to be partially offset by higher operating costs, reflecting higher activity levels, particularly for the floater fleet. Finally, second quarter general and administrative expense is expected to be $19 million to $21 million as compared to $19 million in the first quarter. As a result, adjusted EBITDA for the second quarter is expected to be approximately $25 million as compared to negative $31 million in the first quarter, and adjusted EBITDA is expected to be $45 million to $50 million compared to $31 million in the first quarter. Moving now to capital expenditures. First quarter CapEx was $38 million, of which $12 million was maintenance CapEx and $26 million related to enhancements and upgrades. The enhancements and upgrades include $13 million of reactivation costs and $13 million of contract or region-specific upgrades, primarily related to Valaris DS-4 and DS-11. Second quarter CapEx is expected to be $100 million to $110 million, of which approximately $25 million is expected to be maintenance CapEx and the remainder is expected for enhancements and upgrades. The enhancements and upgrades are anticipated to include approximately $15 million of reactivation costs with the remainder for contract or region-specific upgrades, the majority of which is related to Valaris DS-11. Moving now to full year 2022 guidance. Revenues are expected to be $1.5 billion to $1.55 billion. Contract drilling expense is anticipated to be $1.25 billion to $1.3 billion, inclusive of approximately $80 million to $85 million of reactivation expense substantially all of which is expected to be incurred during the first half of the year. We continue to estimate G&A expense of $80 million to $85 million, which combined with $120 million to $125 million of support costs included within contract drilling expense provides total onshore support costs of approximately $200 million to $210 million in 2022, unchanged from our prior guidance. Some of these items provides adjusted EBITDA of $160 million to $190 million and adjusted EBITDAR of $240 million to $270 million. In terms of our value drivers, this translates to expected full year 2022 operating margin, exclusive of onshore support and G&A expense of $325 million to $350 million for the active fleet or $410 million to $435 million when adjusting for onetime reactivation costs of $80 million to $85 million. Operating margin for our leased and managed rigs is expected to be $75 million to $80 million, and we expect carrying costs of approximately $45 million for the stacked fleet. Our 2022 capital expenditures guidance of $225 million to $250 million remains unchanged from our fourth quarter conference call. This guidance continues to assume reactivations announced to date, but does not include any potential incremental reactivations for the rest of the stack fleet. As Anton noted, we will remain highly disciplined when evaluating opportunities for future reactivations. Based on current contract lead times, particularly for floaters. If we were to reactivate additional rigs in 2022, it would have a negative impact on 2022 EBITDA and CapEx, but would increase earnings and cash flows in future years. While 2022 CapEx is expected to be in the range of $225 million to $250 million, we anticipate receiving approximately $160 million in upfront payments from customers in 2022, related to capital reimbursements and mobilization fees, of which approximately $90 million is associated with DS-11. As a reminder, these and any other upfront customer payments and the related revenues are not included in the contract backlog, average day rates or EBITDA reported in our quarterly filings. And for some of our contracts, these represent a meaningful portion of the total contract value. Based on this guidance and our current market outlook and as we've mentioned, we expect that financial results will improve meaningfully as we complete our 4 floater reactivations in the second quarter and capitalize on opportunities to return additional high-quality stacked rigs to the active fleet in this improving market for contracts that provide meaningful returns. Now I'll move to first quarter results as well as the second quarter and full year 2022 outlook for ARO Drilling, our 50-50 joint venture with Saudi Aramco. As a reminder, ARO is not consolidated in the financial results of Valaris. ARo EBITDA increased to $22 million in the first quarter from $11 million in the prior quarter, primarily due to higher utilization. ARO's second quarter 2022 EBITDA is expected to be relatively in line with the first quarter. ARO's full year 2022 EBITDA is expected to be in the range of $80 million to $90 million. This is lower than our prior guidance range of $90 million to $100 million, primarily due to a later-than-expected start-up for Valaris 140 and an expected delay in delivery of the first newbuild rig to early 2023. Finally, I will provide a brief overview of our financial position. Valaris has the strongest balance sheet in the offshore drilling sector. As of quarter end, we had cash and cash equivalents of $578 million plus $30 million of restricted cash, which does not include the $125 million received in our recently completed sale of the Valaris 113 and 114. Our only tranche of debt is our $550 million senior secured notes due in 2028. The coupon for the note is 8.25% if paid in cash, 10.25% if paid half cash, half pick and 12% if we elect to pick the entire interest payment. The second interest payment of $23 million was paid in cash this month, and we will pay the next installment in cash in November of this year. As we've previously mentioned, the note provides a pari-passu debt basket of $275 million and junior secured debt capacity of the greater of $200 million or 8% of total assets. In closing, our industry-leading balance sheet, best-in-class operational performance and high-quality modern fleet position us well to capitalize on contracting and strategic opportunities as they arise. We will continue to be disciplined in our allocation of capital as we focus on driving increased earnings and maximizing cash flow from our growing active fleet, and we will only reactivate further stacked assets for opportunities that provide meaningful returns. We will also be value-driven as demonstrated by our recent sale of stacked jackups, Valaris 113 and 114 for a total of $125 million, a transaction that is highly accretive to our shareholders and well above the value implied by our enterprise value for those rigs and the rest of our benign environment jackups. We will continually assess our fleet for retirement and divestiture candidates. And where it makes economic sense to do so, we will sell rigs or responsibly retire them. We've now reached the end of our prepared remarks. Operator, please open the line for questions.
