AstraZeneca

Short answer: Write the company name as AstraZeneca - one word, capital A and capital Z. No space, no hyphen; form possessives as AstraZeneca's.

Quick answer

Correct: AstraZeneca

Avoid: Astra Zeneca, Astra-Zeneca, Astrazeneca
Possessive: AstraZeneca's (e.g., AstraZeneca's report)

Core explanation: treat the brand as a single proper noun

AstraZeneca is the company's official spelling. Match it in prose, citations, and metadata to avoid typos, inconsistent search results, and style conflicts.

Official: AstraZeneca
Common wrongs: Astra Zeneca, Astra-Zeneca, astrazeneca

Wrong: Astra Zeneca announced new trial data.
Right: AstraZeneca announced new trial data.

Spacing errors: where writers split the name

The most frequent mistake is inserting a space. That damages searchability and looks like a typo in press releases, CVs, and bibliographies.

Search engines and internal searches treat "Astra Zeneca" differently from "AstraZeneca".
Keep the name intact before adding punctuation, possessives, or file extensions.

Wrong: Please upload Astra Zeneca_report.pdf to the drive.
Right: Please upload AstraZeneca_report.pdf to the drive.
Wrong: We referenced 'Astra Zeneca' in the bibliography.
Right: We referenced 'AstraZeneca' in the bibliography.

Hyphenation & punctuation: don't over-correct

Do not hyphenate the brand. Treat AstraZeneca like any proper noun when adding punctuation or forming compounds.

Wrong: We signed an MOU with Astra-Zeneca.
Right: We signed an MOU with AstraZeneca.
Wrong: Astra-Zeneca's statement arrived today.
Right: AstraZeneca's statement arrived today.

Grammar & capitalization: how the name behaves in sentences

Capitalize the A and Z in running text. Lowercase forms are acceptable in URLs or code, but not in prose.

Correct: AstraZeneca is expanding its trial network.
Avoid: astrazeneca, Astrazeneca (only A capitalized)

Wrong: astrazeneca announced a new partnership.
Right: AstraZeneca announced a new partnership.
Wrong: Astrazeneca's data set is open.
Right: AstraZeneca's data set is open.

Add AstraZeneca to your style guide and CMS spell-check dictionary if you publish often.
Keep a one-line brand checklist (name form, possessive rule, filename rule) in team templates.
