Citigroup's headline trajectory is genuinely improving. Revenue has risen for five straight years ($71.9B in FY2021 to $85.2B in FY2025, +5.6% YoY), and after the FY2023 earnings trough of $9.23B, net income has rebuilt to $14.3B (+12.8%). Diluted EPS grew even faster at +17.7% to $6.99 because management retired 7.2% of the share count — the $13.3B of buybacks in the XBRL data is up 435.6% year over year, the clearest signal in this filing that Citi is leaning hard on capital return. Cash and equivalents jumped 26.4% to $350B and the dividend rose to $5.37B, so the capital-return program is well funded.

The quality underneath is the catch. Return on equity is just 6.7% — far below the ~10% cost of equity a bank needs to create value, which is why stockholders' equity grew only 1.8% despite a profitable year. The market is nonetheless paying 20.5x trailing earnings, a multiple that would be full even for a high-return bank and looks expensive for one earning sub-cost-of-capital returns. Against the ~$121 book value per share derived from $212B equity over 1.75B shares, the $143 price is ~1.18x book — a premium, not the discount Citi historically carried. Much of the EPS growth is financial engineering: net income of $14.3B is still roughly a third below FY2021's $22.0B, so the franchise has not rebuilt its prior earnings power — the buyback is doing the heavy lifting.
