An audio-only earnings call runs over phone lines with an operator managing Q&A. A webcast streams audio or video with synced slides to any browser. Audio-only is simpler and analyst-friendly; a webcast reaches retail investors and shows your story. Most public companies now run both together.

The two formats

Audio-only conference call. Participants dial a phone number. A live operator greets them, keeps listeners muted and runs the Q&A queue. Analysts are used to it, and it works anywhere with a phone signal.

Webcast. Participants click a link and watch in a browser: audio or video, with slides that advance in sync. No downloads. Questions come in by text, or by phone when paired with a dial-in.

When audio-only is enough

  • Your audience is mainly sell-side analysts who prefer to call in.
  • Results are straightforward, with no visual story to tell.
  • You need a call stood up quickly or on a tight budget.

Audio-only doesn't mean basic. Operator-assisted calls still give you participant screening, a managed Q&A queue, recording and replay.

When to add a webcast

  • You have meaningful retail or international shareholders.
  • Your results benefit from charts, guidance bridges or product visuals.
  • You want engagement data: who attended, for how long, from where.
  • You need captioning or translation for accessibility or global reach.
  • You're running a larger event, like an investor day or a hybrid results presentation.

Why most issuers run both

Analysts ask questions by phone. Investors watch the webcast. A combined format serves both without making either compromise. Streamlined bridges the operator-assisted call directly into the webcast, so phone and web audiences hear the same feed with no delay mismatch. Web viewers can submit questions to the same moderated queue.

Combined format also strengthens your public-access position under Reg FD and MAR: more ways in means broader access.

What drives cost

  • Audience size and number of international dial-ins
  • Call length
  • Video vs. audio-only webcast
  • Add-ons: captioning, translation, transcript, extended replay hosting
  • Producer and operator staffing

FAQ's

Is a webcast required for an earnings call?

Yes. On a combined call, analysts ask live by phone through the operator queue, and webcast viewers type questions to a moderator.

Can analysts ask questions on a webcast?

Yes. On a combined call, analysts ask live by phone through the operator queue, and webcast viewers type questions to a moderator.

Does a webcast have a delay?

Streaming typically runs a few seconds to around 30 seconds behind live audio. That's why analysts usually ask questions by phone rather than from the webcast.

Can we run a video webcast instead of audio?

Yes. Video adds presence for investor days and results presentations. Many companies use audio with slides for quarterly calls and video for larger events.

What factors affect the cost of an earnings call webcast?

The main cost factors are audience size, international dial-in requirements, call length, webcast type, and add-ons such as captioning, translation, transcripts and extended replay hosting. Producer and operator staffing can also affect the total cost.
