Thank you, Richard. First quarter adjusted EBITDA and adjusted earnings were $95 million and $42 million or $0.69 per share. The refining segment reported adjusted EBITDA of $81 million compared to $107 million in the fourth quarter of last year.
In Hawaii, the Singapore Index averaged $18.67 per barrel and our land accrue differential was $6.60, resulting in a combined index of approximately $12 per barrel. Hawaii margin capture was 116%, reflecting the benefits of elevated clean product freight and strong commercial execution.
Looking ahead to the second quarter, we expect our Hawaii crude differentials to land between $5 and $5.50 per barrel, and we have continued our product crack hedging framework with approximately 26% and of our second quarter sales hedged at $20 per barrel.
In Billings, our Gulf Coast index averaged $21.34 per barrel, margin capture was 65%, reflecting seasonally soft market conditions. Upper Rockies, gasoline and diesel cracks relative to the Gulf Coast have rebounded quarter-to-date, improving by approximately $9 and $16 per barrel, respectively.
The second quarter billings turnaround is expected to impact gross margin by $4 to $5 per barrel, and we expect operating costs to remain flat relative to the first quarter. In Wyoming, captured to the Gulf Coast index was 70%, reflecting similar seasonal dynamics as Billings.
Lower Rockies markets were particularly weak during the first quarter, reflecting strong refinery utilizations and softer demand in January. Rapid City gasoline spreads to the Gulf Coast have improved $10 per barrel quarter-to-date, and we are well positioned ahead of the peak summer season.
Lastly, in Washington, the PNW Index averaged $20.48 per barrel during the first quarter. Margin capture was 30%, including an approximate $2 per barrel impact from the planned refinery outage. Looking to Q2, our PNW index has improved $7.50 per barrel quarter-to-date, driven by expanding gasoline margins in the region.
The Logistics segment reported adjusted EBITDA of $28 million in the first quarter compared to $24 million in the fourth quarter, reflecting strong system utilization and lower operating costs.
Our retail segment reported adjusted EBITDA of $14 million in the first quarter compared to $17 million in the fourth quarter. Same-store sales growth was partially offset by softer retail fuel margins due to rising wholesale prices. Corporate expenses and adjusted EBITDA were $29 million in the first quarter compared to $26 million in the fourth quarter.
First quarter expenses included $5 million related to advancing our renewable development activities. With our pivot from the larger SAF and green hydrogen project in Tacoma, we expect our renewable spending to reduce to $2 million to $3 million per quarter for the remainder of the year.
Cash provided by operations in the first quarter totaled $83 million, excluding a $44 million working capital outflow related to an increase in trade receivables and $13 million in turnaround expenditures.
Cash used in investing activities totaled $23 million, primarily related to CapEx. Total liquidity as of March 31 was $575 million made up of $228 million in cash and $347 million in availability. We further reduced our cost of debt capital with the recent refinancing activities.
In April, we repriced our $545 million term loan, reducing annual interest expense by $3 million. In March, we expanded the capacity of our asset-based loan from $900 million to $1.4 billion as we plan to refinance our existing Hawaii intermediation for a combination of borrowings under the ABL and a smaller crude oil intermediation.
The shift towards ABL financing in Hawaii is expected to reduce working capital costs by $10 million annually with Hawaii gross margin improving by approximately $20 million per year, partially offset by a $10 million increase in annual interest costs.
Lastly, we've continued our opportunistic approach to share repurchases with $32 million during the first quarter and $73 million year-to-date at an average price of $34 per share. The strong balance sheet heading into the summer driving season, we are well positioned to pursue our strategic growth objectives while opportunistically repurchasing our common stock at attractive prices.
This concludes our prepared remarks. Operator, we'll turn it to you for Q&A.
