Centuri Fund Exit Raises Questions Despite Strong Growth

ACK Asset Management LLC sold its entire $29 million stake in Centuri Holdings during Q4 2026, completely exiting its position of 1.375 million shares. This exit came despite Centuri reporting record quarterly revenue of $850 million in November, representing 18.1% year-over-year growth. The company's underlying performance was even stronger, with base revenue (excluding storm work) growing 25% and base gross profit up 28%.

Centuri's operational momentum is undeniable - the company secured $815 million in quarterly bookings, driving its backlog to a record $5.9 billion. Adjusted EBITDA reached $75.2 million while adjusted diluted EPS improved to $0.19 from $0.06 a year ago. Shares have performed exceptionally well, up 45.9% over the past year and significantly outperforming the S&P 500.

The timing of ACK's exit is particularly noteworthy given that Centuri shares were trading at $31.11 when the filing was made, near their recent highs. The fund maintained positions in other industrial names like Materion and Granite Construction, making Centuri's complete removal from their portfolio stand out.

Centuri provides critical utility infrastructure services across North America, focusing on gas and electric utility maintenance and modernization. The company serves major utility providers and has exposure to growing end markets like renewable energy and data centers.

This transaction matters because it highlights the tension between strong operational performance and valuation concerns. While Centuri's record backlog and revenue growth suggest durable demand from utility infrastructure modernization, a sophisticated investor decided to take profits after substantial share price appreciation.

The exit raises questions about whether current valuations adequately reflect execution risks, particularly around margin discipline and leverage. Centuri operates in a capital-intensive industry where converting backlog into profits requires careful management of costs and project execution.

For infrastructure investors, the sector's long-term tailwinds remain intact - aging utility networks need modernization, renewable energy transitions require new infrastructure, and data center growth demands reliable power connections. However, individual stock selection becomes critical when institutional investors show divergent views.

The mixed signals create uncertainty for retail investors. On one hand, the fundamental business appears strong with visible revenue streams. On the other, a major fund's complete exit suggests they see better opportunities elsewhere or believe the stock has reached full valuation.

This situation underscores the importance of monitoring both operational metrics and institutional sentiment, particularly for stocks that have experienced significant price appreciation in a short period.
