オンセミ（onsemi Nasdaq: ON) とSynaptics Incorporated（Nasdaq: SYNA）は本日、オンセミがSynapticsを全株式交換による取引（オールストック取引）により買収する最終契約を締結したことを発表しました。本取引における総企業価値（EV）は約70億米ドルとなります。
本取引は、Synaptics株式1株に対してオンセミ普通株式1.350株を割り当てる固定交換比率に基づいており、直近10営業日における両社の出来高加重平均株価に対して約19％のプレミアムを反映しています。
本統合により、オンセミはインテリジェントシステム分野におけるグローバルリーダーへの進化を加速する見込みです。Synapticsの差別化されたエッジAIコンピューティング事業ならびにヒューマンマシンインターフェースおよびワイヤレス接続ソリューションの強力なポートフォリオを取り込むことで、オンセミは電源およびセンシングの領域を超え、インテリジェントシステムへと能力を拡張し、幅広いエンドマーケットに対してより高い価値を提供していきます。
また、自動車、産業機器、AIデータセンター分野で培ってきたオンセミの専門性を基盤に、本統合プラットフォームはフィジカルAIの中核にオンセミを位置付けることを目指しており、2030年までにオンセミの総アドレス可能市場（TAM）を300億ドル拡大し、2,430億ドル規模へと成長させる可能性があります。
オンセミの社長 兼 最高経営責任者（CEO）であるHassane El-Khouryは次のように述べています。
「人工知能がクラウドの枠を超え、自動車や産業分野を含む現実世界へと広がる中、次のイノベーションの段階は、リアルタイムで『認識・判断・行動・適応』できるシステムに依存するものと考えています。フィジカルAIへの移行には、“Power、Sense、Connected Compute、Control”がシームレスに連携することが求められます。Synapticsの統合は、当社をこれら4つの中核領域の交点に位置付けることに寄与し、AIデータセンターを超えてエッジアプリケーションに広がる、より大きなAI機会の獲得につながるものと見込まれます。本取引により、接続コンピュート機能を速やかに追加するとともに、ソフトウェアおよびエコシステムの展開を拡大し、顧客が求めるインテリジェントシステムの提供を通じて、より高い価値創出につなげていくことを目指します。」
Synapticsの社長兼CEOであるRahul Patel氏は次のように述べています。
「本日の発表は、SynapticsのエッジAIおよびフィジカルAI分野における成長とリーダーシップを加速させる重要な一歩となります。オンセミとの協業により、Synapticsが持つAIネイティブなコンピュート、コネクティビティ、ヒューマンマシンインターフェースの強みと、オンセミが誇るインテリジェントな電源およびセンシング分野でのリーダーシップを組み合わせ、エッジAIスタックのあらゆるレイヤーにわたる統合ソリューションと開発プラットフォームを顧客に提供していきます。これにより、顧客との関係をさらに深化させるとともに、より大きな総アドレス可能市場へと事業を拡大していきます。
また、全株式交換による本件は、株主の皆様が今後の魅力的な成長および価値創出の機会に参加できる仕組みとなっています。オンセミの経営陣とともに、この統合の持つ潜在的な価値を最大限に引き出していくことを楽しみにしています。」
