Outlook 2025–2028

2025至2028年主要成長動能來自機隊擴張、長程航線開發、北美與亞太轉運市場、AI與電商帶動的航空貨運,以及桃園機場第三航廈與航空城長期建設。公司2025年法人說明會指出2025年1至11月營收皆為年增,惟4月起受對等關稅不確定、日本大地震謠言、美國簽證緊縮與新機交付前置成本影響,客運需求與獲利承壓,第四季載客率及訂位回溫。機隊方面,2025年法人說明會列示現有機隊29架,2026年目標43架,包含A350-1000由0架增至6架、A330-900由6架增至11架、A321neo由13架增至16架、A350-900維持10架;媒體及產業資料亦指出2026年為交機高峰,客貨運運能可望大幅增加。貨運方面,公司2024年年報揭露已於2024年2月與空中巴士簽署A350F新世代廣體貨機購機合約,預計自2028年前後陸續交機並以全貨機營運,將擴大北美、亞洲及高價值貨物運輸能力;公司2025年1至9月貨運收入35.8億元、年增69%,載貨量6.3萬噸、年增65%,並稱受惠AI產業暢旺。航網方面,短期策略包含提升北美西岸、日本與東南亞航班密度、深化台北樞紐及台中基地;中長期評估歐洲、大洋洲及更多北美航點。主要風險包含油價及匯率波動、國際政治與關稅不確定、航空需求循環、機隊快速擴張造成折舊/租賃/人力訓練前置成本、空巴供應鏈與交機延遲、長程航線培育期載客率與收益率壓力、華航與長榮航等既有航空公司競爭、碳排及永續航空燃料成本上升。2027至2028年的部分航線與交機時程屬公司展望與媒體報導,實際仍須以公司公告、民航主管機關核准與交機進度為準。

Method and limitations

  • All returns use adjusted close (etl:adj_close), already adjusted for dividends and splits.
  • Excess return is measured against the TAIEX total-return index (dividends included).
  • Valuation regime and percentile stats use an expanding own-history window (no future data).
  • Revenue-signal event dates align to the first trading day after the filing deadline, avoiding look-ahead.
  • Event samples may overlap in time; stats describe historical distribution only and are less reliable when samples are few.
