“Trades During the Quarter ● Exited: Cannae Holdings, Inc. (CNNE) - Underperformed in recent years and was only 1% of the portfolio. Our initial thesis centered on Bill Foley's ability to create value and the most valuable asset of CNNE was Dun & Bradstreet. That investment has not worked out and CNNE shares have lagged the broader market. We elected to sell the remaining position. ● Reduced: AerCap Holdings (AER) - We trimmed AER on strength. The stock has significantly outperformed the broader market since early 2021. We remain confident in the outlook for air travel and for AER to benefit by leasing planes to the largest airlines. ● Increased: Saia, Inc. (SAIA) - With recent weakness and a smaller beginning weight in the portfolio, we felt it was prudent to add to the shares and make it a 3% position. ● Increased: Zebra Technologies Corporation (ZBRA) - Added to the position following weakness in the shares early in the year. Concerns around tariffs and weaker tech spending provided a more attractive valuation. ● Initiated: Somnigroup International Inc (SGI) – Formerly Tempur Sealy, SGI is the combined company of Tempur Sealy the acquired Mattress Firm.”
