Craig S. Billings
President And Chief Financial Officer at Wynn Resorts
Thanks, Matt. As Matt noted, our Macau operations delivered $67.6 million of EBITDA in the quarter on $454.4 million of operating revenue. Our EBITDA was driven by encouraging gaming and nongaming performance combined with solid cost controls with particular strength in April and May. Gross gaming revenue per day in 2Q 2021 was approximately 31% of Q2 2019 led by the premium mass segment. Our 2Q results in Macau were positively impacted by higher-than-normal VIP table games hold that increased EBITDA by approximately $10 million from a normalized level. With respect to cost controls, our opex, excluding gaming tax, was $2.3 million per day in the quarter. This is down 23% from $3 million per day in the fourth quarter of 2019 and only up slightly sequentially despite the increase in revenue. We continue to be well positioned to drive strong operating leverage as the business recovers. At Wynn Las Vegas, we generated $133.2 million of adjusted property EBITDA on $355.1 million of operating revenue with particular strength on the weekend. In the casino, we saw broad-based strength across key segments, with slot handle 37% above 2Q 2019 levels, and table drop only 3% below to 2Q 2019.
The team in Las Vegas has done a great job of controlling costs without negatively impacting the guest experience, delivering a record adjusted property EBITDA margin of 37.5% in the quarter. opex per day, again excluding gaming taxes, decreased 24% to $2.3 million per day in the second quarter of 2021 from $3 million per day in the fourth quarter of 2019. While opex increased approximately 45% sequentially from $1.6 million in 1Q 2021, revenue nearly doubled, driving strong operating leverage. In Boston, as Matt mentioned, we generated another record quarter with adjusted property EBITDA of $46.9 million on a record EBITDA margin of 28.4%. Similar to Las Vegas, we have remained very disciplined on the cost side with opex per day, excluding gaming tax, of $870,000 in the quarter, a decrease of over 30% compared to $1.3 million per day in Q4 2019, and a modest increase relative to the first quarter of 2021 on the back of improved business volumes and increased operating hours. Turning to Wynn Interactive. We spent much of the quarter aggressively advancing our product features and building a robust marketing campaign ahead of the 2021 football season. Strategic highlights over the past few months include the recent launch of our web applications in Indiana, Colorado, Tennessee, New Jersey and Virginia, which we expect to help drive user acquisition over time.
We've also strengthened our third-party partnerships through agreements with the Detroit Lions, the Colorado Rockies and Cumulus Media. We've also announced several new high profile brand ambassadors, including Tim Howard and Chad Johnson, with more to come. Additionally, as sports and sports media continue to converge, we've partnered with several engaging content creators, including Chris Long, to develop unique sports theme programming from the new Blue Wire podcast studio at Wynn Las Vegas, which is scheduled to open in a few weeks. Wynn Interactive is now powered by just over 340 employees and is run rating $110 million in annualized gross revenue as of July. We modestly exceeded the Q2 results underpinning the projections published in connection with our announced de-SPAC with Austerlitz in May despite lower than expected user acquisition spend. We anticipate our revenue to accelerate over the remainder of the year, particularly in the fourth quarter, as we rollout our thoughtful and unique marketing campaign and our new product features.
Our total acquisition spending declined sequentially, and we believe our ability to exceed our revenue projections on lower acquisition spend is a testament to the brand's ability to drive retention and higher average spend per customer. We look forward to sharing more details on this business during a presentation to sell-side analysts planned for September, along with a slide deck that will be posted on our IR website at that time. Turning to the balance sheet. Our liquidity position remains very strong with global cash and revolver availability of over $3.9 billion as of June 30. In Macau, we had approximately $2 billion of available liquidity as of June 30. In the US, we had total liquidity of approximately $1.9 billion on June 30th, with a substantially lower daily cash burn globally compared to the first quarter of 2021.
Earlier this week, a subsidiary of Wynn Macau Limited received commitments for a new $1.5 billion senior unsecured revolving credit facility that will mature in 2025. The arrangement includes broad participation by our bank group of supportive existing lenders, including local and international banks. Borrowings under the new facility, along with cash on hand, will be used to refinance and retire our existing senior secured credit facility in Macau. Finally, our capex in the quarter was $70 million, and we remain prudent with respect to CapEx, while we gain further confidence in the recovery.
With that, we will now turn it over to Q&A. Operator?
