AI Analysis · Q1 2026

Polaris Capital Management put $36.0 million into a new EMN position while cutting MKSI by an estimated $30.0 million. That near-dollar-for-dollar pivot was the quarter's defining change, but it sat inside a much broader harvest: 29 continuing positions were reduced and six were sold outright, versus only five increases and six new stakes. The portfolio still edged up to $1.2 billion because market-value gains masked many of those sales.

The contrast is clearest among the largest holdings. Polaris trimmed BPOP, UTHR and Jazz Pharmaceuticals even as all three positions rose in reported value, and sold MPC shares while that stake gained $11.4 million. These were reductions, not purchases. Meanwhile, LNTH received the largest add to an existing holding and SLM was increased despite a falling position value. The quarter preserved a diversified financials-and-healthcare core while reallocating capital from MKSI, Sally Beauty and UNH toward EMN and a smaller set of targeted additions.

LNTH received the largest addition to an existing holding. Polaris bought 79,000 shares, an estimated $6.0 million purchase, lifting the position to $46.8 million and 3.8% of the portfolio. SLM was increased by 183,500 shares, roughly $3.9 million of buying, even though its reported value declined by $3.1 million. Price weakness masked that purchase. GLPI and INGR received smaller additions, while JPM was essentially maintained.

Several large positions present the opposite accounting illusion. Polaris sold 34,200 BPOP shares, worth an estimated $4.6 million, yet the remaining stake's value rose by $2.0 million. It trimmed UTHR by about $4.2 million while the stake gained $6.8 million in reported value, and reduced Jazz Pharmaceuticals by roughly $3.2 million while that position rose by $5.0 million. MPC is even more pronounced: an estimated $2.0 million of share selling coincided with an $11.4 million increase in position value. Appreciation masked each sale.
