“Along with technology, the industrials and consumer staples sectors detracted from this quarter’s returns. The portfolio’s industrials holdings dropped -4% in the quarter, falling well short of the benchmark’s +16% industrials return. Companies in the professional services industry group (Leidos, Broadridge, Tetra Tech) were caught in the downdraft of AI uncertainty and drug portfolio returns lower.”

Tetra Tech - June 2026
“Interparfums (IPAR) is a pure-play fragrance company, primarily licensing brands in the prestige/luxury category. The company operates a portfolio of 30 brands across 120 countries, using an asset light model that spans the entire creative and commercial process including fragrance design, packaging, marketing, and distribution. As a scaled but still niche participant in the growing global fragrance industry, IPAR participates in the premium and prestige categories and increasingly in the faster growing luxury segment as well. It should continue to benet from the long-term growth trends and resilience of the overall industry while also adding new brands to its portfolio. We were able to initiate the position at an attractive valuation as growth temporarily slowed in 2026 following a strong three-year run. EPS and margins retreated slightly given the nonrecurrence of one-time benets as well as heightened marketing investments in preparation for a historically large slate of new fragrance launches in 2027 and 2028. These launches should drive a reacceleration of growth and margin expansion. Tetra Tech (TTEK) is a leading high-end technical consulting and engineering services rm focused on water, environmental science, and sustainable infrastructure.”
Tetra Tech - New positionCooke & Bieler SMID Cap Value Equity StrategyJune 2026
“Tetra Tech (TTEK) is a leading high-end technical consulting and engineering services rm focused on water, environmental science, and sustainable infrastructure. The company operates primarily at the front end of projects, helping clients dene problems, navigate regulation, design solutions, and manage complex programs, while taking limited construction risk. More than 85% of the business is tied to water-related end markets, including water supply, wastewater, ood protection, coastal resilience, PFAS remediation, and infrastructure for data centers, mining, and power generation. While the wind-down of USAID work creates a near-term revenue headwind, the underlying business remains well positioned to grow through organic opportunities, bolt-on acquisitions, modest share repurchases, and gradual margin expansion. We believe TTEK’s technical expertise, long-standing customer relationships, asset-light model, and disciplined capital allocation support attractive long-term compounding potential.”
