long-term notes financial

"placement of long-term notes in the Mexican market for an aggregate amount"

Master Development Program financial

"used to fund committed investments under the Master Development Program"

A master development program is an overarching plan that coordinates all steps needed to develop a drug, medical device, or therapy across multiple studies, indications, or stages. Think of it as a blueprint that ties together clinical trials, regulatory strategy, manufacturing scale-up, and timelines so a single coordinated effort can address several related goals rather than separate, isolated projects. Investors use it to gauge how organized and efficient a company’s development activities and regulatory pathway may be.

Afores financial

"participation of pension funds “Afores”, governmental entities, insurance companies"

forward-looking statements regulatory

"This report may contain forward-looking information and statements"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Form 20-F regulatory

"those discussed in our most recent annual report filed on Form 20-F"

Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.
