<div id="readability-page-1"><article>SANTIAGO, Chile, Jan. 30, 2026 (GLOBE NEWSWIRE) -- Banco Santander Chile (NYSE: BSAC; SSE: Bsantander) announced today its results1 for the twelve-month period ended December 31, 2025, and fourth quarter 2025 (4Q25). Solid financial performance with a ROAE2 of 23.5% in 12M253. As of December 31, 2025, the Bank's net income attributable to shareholders totaled Ch$ 1.053 billion ($5.59 per share and US$2.48 per ADR), marking a 22.8% increase compared to the same period of the previous year and with a 23.5% ROAE in 12M25 compared to a 20.2% ROAE in 12M244. The increase in results is explained by the growth displayed in the Bank's main revenue streams. Operating income increased 10.2% YoY5, driven by a better net interest margin and adjustments, higher fees and financial transaction results. Compared to the previous quarter (3Q25), net income attributable to shareholders increased 3.2% QoQ6, primarily due to improved margins and fee growth, as well as effective cost control. This resulted in a 21.9% ROAE for 4Q25, marking the seventh consecutive quarter with ROAE above 20%. Strong recovery of the NIM7, reaching 4.0% in 12M25 Net interest income and readjustments (NII) accumulated to December 31, 2025, increased by 10.9% compared to the same period in 2024. This increase in NII resulted from an improvement in the funding cost, which fell from 4.7% to 3.8% in 12M25, explained mostly by the reduction observed on the Monetary Policy rate compared to 2024. As a result, the NIM improved from 3.6% in 12M24 to 4.0% in 12M25. Compared to 3Q25, net interest income and readjustments increased 5.3% QoQ mainly due to lower interest expenses. Customer base expansion continues, with total customers increasing by 6.9% YoY. Our strategy of strengthening digital products has led to continuous growth in our customer base, reaching approximately 4.6 million customers, of which almost 2.3 million are digital customers (85% of our active customers). The bank's market share in current accounts remains strong at 21.8% as of November 2025, driven by increased customer demand for US dollar current accounts, as customers can open these accounts digitally through our platform in just a few simple steps. This also demonstrates the success of Getnet's strategy to promote cross-selling of other products, such as current accounts for SMEs. Net commissions increased 8.9% in 12M25, reaching recurrence8 levels of 63.7%. Net fees increased 8.9% in the twelve months ending December 31, 2025, compared to the same period in 2024, driven by an increase in customers and greater product usage. As a result, the recurrence ratio (total net fees divided by structural support expenses) increased from 60.3% YTD in December 2024 to 63.7% YTD in December 2025, demonstrating that more than half of the Bank's expenses are financed by fees generated by our customers.

Total operating expenses (including other expenses) increased by 1.8% in 12M25 compared to 12M24, driven primarily by administrative expenses related to higher technology spending in the first quarter of 2025, as well as other expenses related to the restructuring of our branch network and the transformation into Work/Café branches.
