Summary

• Tandem Diabetes Care, Inc.'s Board of Directors adopted Amended and Restated Bylaws, effective December 26, 2025, replacing prior bylaws.
• The amendments update advance notice provisions for stockholder director nominations and other business, requiring specific representations regarding proxy solicitations and compliance with Rule 14a-19.
• Nominees will be disregarded if the nominating stockholder fails to comply with Rule 14a-19 requirements or fails to appear at the meeting.
• The number of nominees a stockholder can propose cannot exceed the number of directors to be elected, and substitute nominees require compliance with advance notice provisions.
• Proposing stockholders must provide the full text of their proposals and additional disclosures, including information required for proxy solicitations in election contests.
• The Board is now expressly authorized to cancel, reschedule, or postpone annual or special stockholder meetings.
• Stockholders soliciting proxies must use a proxy card color other than white, with the white card reserved exclusively for the Board.
• Indemnification provisions were updated with technical, modernizing, and clarifying changes.
• Notice provisions throughout the bylaws were conformed to Section 232 of the Delaware General Corporation Law (DGCL).
• Voting standards for director elections were simplified and clarified, with plurality voting for contested elections and majority of votes cast for uncontested elections, determined 10 days prior to notice mailing.
• The requirement for the list of stockholders of record (with home addresses) to be available for inspection at the stockholder meeting was removed, aligning with recent DGCL changes.
• Certain provisions already addressed in the company's Certificate of Incorporation were removed to avoid duplication.
• The federal district courts of the United States of America are designated as the exclusive forum for Securities Act of 1933 claims, unless the Corporation consents otherwise.

Sentiment

Score: 4

Explanation: While some changes modernize bylaws and align with Delaware law, several provisions, particularly those related to shareholder nominations and proxy access, could be perceived as defensive measures that limit shareholder influence. The exclusive forum clause also restricts shareholder litigation options, which may be viewed negatively by some investors.

Positives

• Modernizes and clarifies corporate governance documents, aligning them with current Delaware General Corporation Law (DGCL) standards.
• Enhances clarity in procedures for stockholder meetings, including notice requirements and voting standards.
• Updates indemnification provisions, potentially offering clearer protection for directors and officers.

Negatives

• Tighter advance notice provisions for stockholder nominations and proposals may increase the burden on shareholders seeking to engage in activism or propose alternative directors.
• Reserving the white proxy card exclusively for the Board could be perceived as a measure to disadvantage dissenting shareholders.
• Removal of the requirement for the physical stockholder list to be available at meetings may reduce direct access for shareholders.

Risks

• Potential for increased shareholder dissent or legal challenges if the updated advance notice provisions are perceived as overly restrictive or anti-shareholder.
• The exclusive forum provision for Securities Act claims could limit shareholders' choice of venue for certain types of litigation, potentially increasing litigation costs or complexity for shareholders.

Future Outlook

This filing does not contain forward-looking statements or guidance related to the company's financial performance or operational outlook. It focuses solely on corporate governance amendments.

Management Comments

• The Board of Directors adopted the Amended and Restated Bylaws in connection with a standard periodic review of the company's governance documents.

Industry Context

The amendments reflect a common trend among publicly traded companies to update bylaws to align with evolving corporate governance best practices, respond to changes in state corporate law (like the DGCL), and manage shareholder engagement. Many companies have adopted similar advance notice provisions and exclusive forum clauses to streamline corporate processes and manage potential litigation risks.

Comparison to Industry Standards

• The updated advance notice provisions for shareholder nominations and proposals are consistent with practices adopted by many public companies to manage proxy access and ensure orderly shareholder meetings.
• The reservation of the white proxy card for the Board is a common defensive measure, though it can be viewed as limiting shareholder activist efforts compared to companies that allow more flexibility.
• The adoption of an exclusive forum provision for Securities Act claims is a widespread practice among Delaware corporations, aimed at centralizing litigation in federal courts and avoiding multiple state court actions.

Corporate Governance

Legal Proceedings

• The bylaws establish the federal district courts of the United States of America as the exclusive forum for Securities Act of 1933 claims, which impacts where certain legal proceedings against the company can be brought.

Stakeholder Impact

• Shareholders: The updated advance notice provisions and proxy card rules may impact the ability of activist shareholders to nominate directors or propose business. The exclusive forum clause limits the choice of venue for certain shareholder lawsuits.
• Directors and Officers: Clarified and modernized indemnification provisions offer clearer protection against liabilities incurred in their roles.

Next Steps

• The Amended and Restated Bylaws became effective immediately upon adoption on December 26, 2025.
