In the first stage, each team played the other seven teams in a single
round-robin tournament. Top four teams advanced to the semi-finals, while the bottom team was relegated to the 2027
Campeonato Alagoano Série B. Semi-finals and finals will be played on a home-and-away
two-legged basis with the best overall performance team hosting the second leg. If tied on aggregate, the
penalty shoot-out will be used to determine the winners. Champions and runners-up will qualify for the
2027 Copa do Brasil and
2027 Copa do Nordeste. The third-place team will also qualify for the
2027 Copa do Brasil. The two best teams not already qualified for the 2027 Série A, Série B or Série C will qualify for the
2027 Campeonato Brasileiro Série D. ==Teams==
