Westamerica Bancorporation stock gains as earnings stay in focus

Westamerica Bancorporation stock (ISIN US9290511003) traded at USD 59.57 on Nasdaq at 9:44 a.m. ET on September 22, 2026, up 0.15 percent from the prior close of USD 59.48. The quote sits within a 52-week range of USD 44.93 to USD 63.61, putting the shares USD 4.04 below the high and USD 14.64 above the low.

Quarterly earnings set the baseline

Westamerica Bancorporation reported GAAP earnings per share of USD 1.13 and revenue of USD 62.2 million for its latest reported quarter, Q2 2026, according to Seeking Alpha on September 22, 2026. The reporting-period split matters: the earnings figures describe Q2 2026, while the market quotation reflects September 22, 2026.

The USD 1.13 quarterly EPS and USD 62.2 million revenue provide two operating markers for assessing the bank against its share price. Revenue and earnings are not interchangeable measures, so the stock's valuation remains tied to how consistently the bank converts income into per-share profit across reporting periods.

Stock remains below yearly high

The current USD 59.57 price is 6.35 percent below the 52-week high of USD 63.61 and 32.49 percent above the low of USD 44.93, based on the September 22, 2026 quote. The distance from both reference points gives the market data a more useful frame than the daily move alone.

Market capitalization stood at USD 1.37 billion and volume was 3,624 shares as of the September 22, 2026 snapshot. The reported volume was below the three-month average volume of 200,580 shares, making the small 0.15 percent move a limited activity signal rather than evidence of a broad repricing.
