Key Terms

share buyback program financial

"in accordance with the terms of its share buyback program announced on March 20, 2025"

A share buyback program is when a company uses its cash to repurchase its own outstanding shares from the market, reducing the number of shares available to investors. That matters because it can raise the value of remaining shares and signal management's confidence in the business—similar to a bakery buying back unsold loafs to make each remaining loaf represent a larger share of its oven’s output—though buybacks can also affect cash available for other uses.

volume-weighted average price financial

"at a volume-weighted average price of $13.9712 per Share"

Volume-weighted average price (VWAP) is the average price of a stock over a specific time period where each trade is weighted by the number of shares traded, so larger trades influence the average more than small ones. Investors and traders use VWAP as a reference point to judge whether trades are happening at relatively good or poor prices—like checking the average price paid for an item at a market where bulk purchases count more than single-item buys.

Market Abuse Regulation regulatory

"In accordance with Article 5(1)(b) of Regulation (EU) No 596/2014 (the Market Abuse Regulation)"

Market abuse regulation consists of laws and rules designed to prevent dishonest or manipulative practices in financial markets. It aims to ensure fair and transparent trading, so investors can trust that markets operate honestly, much like rules that keep a game fair. By reducing unfair advantages, it helps protect investor confidence and promotes healthy, efficient markets.

Disclosure Guidance and Transparency Rules regulatory

"for the calculations by which they will determine if they are required to notify their interest... under the FCA's Disclosure Guidance and Transparency Rules"

Disclosure guidance and transparency rules are the standards and regulations that require companies to share clear, timely information about their finances, risks, operations and material events. They matter to investors because consistent, honest reporting is like a car’s dashboard — it reveals the data you need to judge safety and performance and make informed buying or selling decisions. Strong disclosure reduces surprises and helps keep markets fair and efficient.
