Costco Wholesale (ISIN US22160K1051) reported September net sales of USD 30.02 billion, while its market capitalization stood at USD 423.4 billion as of October 13, 2026. In its October 7, 2026 release, GlobeNewswire said sales increased 13.00 percent from USD 26.58 billion a year earlier.

September sales set the tone

The latest monthly update covered the five weeks ended October 4, 2026. Comparable sales increased 11.40 percent, while comparable sales excluding gasoline prices and foreign exchange rose 7.60 percent, giving investors a clearer view of underlying demand.

Digitally enabled sales increased 19.00 percent year over year in the same period. The release also said that the later Labor Day holiday in the United States and Canada added more than 50 basis points to September total and comparable sales.

What drove the annual result?

Costco's fiscal 2026 report provides the broader earnings base behind the monthly figure. According to Costco Wholesale on September 24, 2026, total revenue reached USD 303.154 billion for the 52 weeks ended August 30, 2026, compared with USD 275.235 billion in fiscal 2025. Net income rose to USD 9.226 billion from USD 8.099 billion, while diluted earnings per share increased to USD 20.76 from USD 18.21.

The comparison matters because Costco converted double-digit sales growth into a 13.93 percent increase in net income. The fourth quarter also included a USD 0.15 per diluted share benefit from tariff refunds, a one-off item that limits the direct read-across from quarterly earnings to future margins.

Three dates frame the update

On August 30, 2026, Costco completed the 52-week fiscal year with USD 303.154 billion in total revenue. On September 24, 2026, the company reported fourth-quarter net sales of USD 93.873 billion and net income of USD 2.998 billion. On October 7, 2026, it reported September net sales of USD 30.02 billion, making the monthly release the latest dated operating event.

Market value stays measurable
