What Is the Latest Analyst Price Target?

Market data reports a consensus price target of $139.83 from seven analysts who have rated the stock in the past 12 months, with a high of $155.00 and a low of $130.00. Measured against the $114.64 close on 9 October 2026, the consensus target suggests potential upside of about 22.0%.

The second data set shows a somewhat higher picture: a mean target of $145.09 and a median of $145, with a range of $132 to $155 across 12 analysts.

What Are Wall Street Analysts Saying?

Market data records five Buy ratings, two Hold ratings and no Sell ratings, giving a "Moderate Buy" consensus. The second data set counts seven Strong Buy, four Buy, no Hold and one Strong Sell among its 12 analysts, and labels the consensus "Buy".

Named broker activity on market data includes Rothschild & Co Redburn initiating coverage with a Buy rating and a $132.00 target on 21 September 2026, Barclays lifting its target from $143.00 to $144.00 with an Overweight rating on 8 September, Truist Financial raising its target from $140.00 to $155.00 with a Buy rating on 27 August, and Wells Fargo raising its target from $135.00 to $140.00 with an Overweight rating on 6 August. An independent ratings service cut its rating from Buy to Hold on 25 August without a target. The second data set lists Goldman Sachs as the most recent action, raising its target from $153 to $155 on 6 October 2026.

What Could Help the Stock Reach the Price Target?

Market data says the most recent quarter beat expectations, with earnings per share of $0.60 against $0.54 forecast and revenue of $2.03 billion against $1.97 billion, and that full-year EPS guidance of $5.87 to $5.93 sits above the cited consensus.

Continued revenue growth and guidance that is met or exceeded could support higher earnings estimates.

What Could Prevent the Stock Reaching the Target?

The consensus target sits well above the current price, and analysts' optimism can unwind quickly if growth slows. A single weak quarter, a rise in borrowing costs for a capital-intensive business, or a change in demand for storage and data-centre services could all push estimates lower. The wide gap between the lowest rating on the second data set, a Strong Sell, and the Buy-leaning majority shows that views are not unanimous.

What Should Investors Watch Next?

Investors may wish to watch whether guidance is reaffirmed, whether the $0.864 quarterly dividend reported by market data is maintained, and whether brokers revise targets afterwards.
