$p$-regularity of the $p$-adic valuation of the Fibonacci sequence

We show that the $p$-adic valuation of the sequence of Fibonacci numbers is a $p$-regular sequence for every prime $p$. For $p \neq 2, 5$, we determine that the rank of this sequence is $α(p) + 1$, where $α(m)$ is the restricted period length of the Fibonacci sequence modulo $m$.
