Are there any lock‑up or registration rights agreements that could influence future share sales?

Short answer:

The press release you quoted does not contain any specific language about lock‑up periods or registration‑rights agreements that would affect later sales of the Centuri shares being offered. Consequently, from the information publicly disclosed in the announcement, we cannot identify any such covenants.

Why the answer is limited to “no explicit mention”

Press releases of this type normally give a high‑level overview and direct readers to the filing (e.g., the S‑1 Registration Statement, prospectus supplement, or Form 8‑K) for the exact contractual terms. Since the excerpt you provided does not include those details, we cannot confirm the existence—or the absence—of any lock‑up or registration‑rights provisions.

What lock‑up and registration‑rights provisions usually look like in a secondary offering

Impact on future share sales:

- If a lock‑up exists, the selling shareholder (Centuri, its insiders, or any large investors) would be prohibited from disposing of additional shares until the lock‑up expires. That could delay or stagger future market liquidity.

- If registration‑rights are in place, the shareholder can later register and sell additional shares, but must follow the timing and procedural requirements spelled out in the agreement (notice periods, filing deadlines, etc.). The underwriters typically receive “pig‑gy‑back” rights, meaning they may be entitled to a portion of any subsequent sales, which can affect the net proceeds the shareholder receives.

How to verify whether such agreements exist for this offering

1. Read the S‑1 Registration Statement / Prospectus Supplement

   • The filing (available on the SEC’s EDGAR system) will include a section titled “Lock‑up Agreements” or “Registration Rights Agreement.”
     
   • Look for tables that list each selling shareholder, the number of shares they are selling, and any lock‑up periods that apply.

2. Check the Underwriting Agreement (often attached as an Exhibit)

   • The agreement between Centuri (or Southwest Gas Holdings) and the underwriters (e.g., Goldman Sachs, Morgan Stanley) will spell out any lock‑up covenants, pig‑gy‑back rights, and registration‑rights provisions.

3. Review Any Form 8‑K or 6‑K Filings

   • Companies sometimes file a separate 8‑K to disclose the execution of lock‑up or registration‑rights agreements after the initial press release.

4. Contact Investor Relations

   • The press release provides a contact point. Investor relations can confirm whether any lock‑up or registration‑rights terms are applicable and, if so, their duration.

Bottom‑line answer for the asked question

• Based on the press release you provided, there is no mention of lock‑up periods or registration‑rights agreements.
  
• Therefore, we cannot state from this information alone that any such agreements exist that would influence future share sales.
  
• To determine definitively whether any lock‑up or registration‑rights provisions apply, you should examine the official SEC offering documents (S‑1, prospectus supplement, underwriting agreement) or request clarification from Centuri’s investor‑relations team.
  

If you retrieve those filings and see, for example, a 90‑day lock‑up for certain insiders, that would directly affect when those shareholders could sell additional shares. Likewise, a registration‑rights clause would give those shareholders the ability (and the associated procedural steps) to register future sales. Until those documents are reviewed, the existence and impact of such covenants remain unknown.
