『その隙を、ステージ部門二位につけた来禅が衝いたというわけですね。特に模擬店部門のメイドカフェの得票数が凄まじい！審査の際に物議を醸したという話ですが、実行委員の熱心なプッシュが功を奏した形になりますね！』
The host was announcing that the champion school at a school festival was 来禅高校, whose maid cafe won them a lot of votes.
Hi. What does 形になります mean here? Thank you.
The phrase has very low searchability so that I might miss one or two duplicate questions on this site (somewhat close one), but...
形 has a definition among formal noun usages:
３ 物事の結果としての状態。「どっちつかずの―になる」
Formal nouns are usually appositive not translating very well into English:
実行委員の熱心なプッシュが功を奏した形になります
lit. "It would be a consequence that the (festival) committee members' eager push paid off"
≈ the committee members' hard push has contributed a lot to this result
