What this transaction means for investors

140 Summer Partners runs a concentrated portfolio. It held 22 positions in the fourth quarter. It bought more shares of several of its top holdings last quarter, including raising its stake in Acuity.

Acuity stock has been volatile over the past few years, but the company had a strong year. In fiscal 2025, which ended in August, revenue grew 13% year over year to $4.3 billion. It seems to be building momentum, with revenue up 20% year over year in the most recent quarter.

Despite the stock’s underperformance, the company’s growth could make the stock undervalued. The shares trade at 14 times expected earnings, and analysts expect earnings to grow at an annualized rate of 20% over the next two years.
