"repurchased 30,000 Series A shares of Vista"

shares outstanding financial

"there were 110,557,402 Series A shares outstanding"

Shares outstanding are the total number of a company’s stock units held by all shareholders, including institutional investors and company insiders — think of them as the total number of slices of the company’s ownership pie. Investors use this number to calculate how much of the company each share represents, and it directly affects per-share measures like earnings per share, ownership percentage and valuation; when the slice count changes, an investor’s claim and the company’s per-share metrics change too.

held in Treasury financial

"1,744,351 Series A shares were held in Treasury"

value-added tax financial

"excluding fees and value-added tax"

A value-added tax (VAT) is a consumption tax charged on the extra value a business creates when producing or selling goods and services; businesses collect the tax at each step and remit it to the government, while the final cost is borne by the consumer. Investors should care because VAT affects companies’ pricing, profit margins, cash flow timing and compliance costs — like toll booths on a supply chain that can change demand and profitability.
