This paper investigates the prospects for applying the Z-Score model to the assessment of financial stabilityin the Uzbek banking sector. The study is based on monthly financial data spanning 2020 to 2024 for three institutions -Aloqabank, Asia Alliance Bank, and Mikrokreditbank which represent distinct ownership models and strategic orientationswithin the national banking system. The bank-adapted Z-Score formula, Z = (μROA + E/A) / σROA, is employed toquantify each institution's distance from insolvency, where μROA denotes mean annual return on assets, E/A is the yearendequity-to-assets ratio, and σROA captures the standard deviation of monthly ROA observations within each year.The results demonstrate that Asia Alliance Bank posted a sustained upward trajectory in financial stability, with Z-Scoresrising from 20.93 in 2021 to 53.36 in 2024, driven by robust profitability gains (ROA increasing from 0.54% to 4.91%) andsteadily improving cost efficiency (CIR declining from 49.43% to 35.45%). Aloqabank exhibited moderate but variablestability, peaking at 34.42 in 2021, declining to a trough of 14.82 in 2023 amid earnings volatility and a temporary breachof the regulatory capital adequacy minimum, before partially recovering to 22.19 in 2024. Mikrokreditbank recordedexceptionally high Z-Scores of 100.85, 133.83, and 351.63 in 2021–2023 respectively, reflecting an extremely low standarddeviation of ROA characteristic of government-directed specialized lending, but experienced a sharp deterioration to 7.86in 2024 when the institution posted negative mean ROA of −0.57%. The findings contribute to the empirical literature onbanking stability in transition economies and yield actionable implications for bank supervisors and management teams
