First Citizens BancShares (FCNCA) stock plummeted 5.25% during Friday's intraday trading session, a sharp reversal from its pre-market gains.

The decline occurred even though the company reported fourth-quarter adjusted earnings of $51.27 per share, significantly beating the IBES estimate of $43.90. Revenue, expressed as the sum of net interest income and total noninterest income, also rose to $2.44 billion, surpassing analyst expectations.

The stock's downturn appears linked to broader sector weakness, with financial stocks leaning lower premarket. Additionally, investors may be focusing on certain details within the earnings report, such as a decrease in net interest margin and an increase in adjusted noninterest expense, alongside the company's provided net interest income outlook for the first quarter and full year 2026.
