Earlier this morning, we released our fiscal 2026 second quarter results along with certain outlook information. Our revenue for the quarter was $1.38 billion, a 14.5% increase over the prior year. This top line growth combined with our strategic initiatives drove adjusted EBITDA to $205.5 million, representing a 14.9% margin and a 29.8% increase over the prior year. Our commitment to efficient cash flow management also paid off as we improved our DSOs by 9 days year-over-year, ending the quarter at 108 days.
We finished the quarter with total backlog of $8 billion and next 12 months backlog of $4.6 billion. We continue to cultivate a healthy pipeline and diverse customer and program opportunities. As a reminder, the size and complexity of these opportunities can lead to short term variation in reported backlog resulting from the timing of when contracts are signed. This award will be reported in our Q3 backlog and is a clear testament to Dycom's breadth of capabilities across our national footprint.
The increasing addressable market coupled with our proven ability to execute bolster our confidence to achieve our full year growth target. As a result, we are reaffirming our fiscal 2026 revenue outlook range of $5.29 billion to $5.425 billion. The demand for digital infrastructure is accelerating and Dycom is uniquely positioned to lead. Shortly after the Q1 earnings call, AT&T and Lumen announced AT&T's acquisition of the majority of Lumen's mass market segment.
