Filing Explained

Group Holdings - Frontier LLC reports sole voting and disposition power over a 9.9% stake in Frontier Group Holdings.

The July 13, 2026 Schedule 13G/A is Amendment No. 1 to a filing made on April 12, 2024; it reports that Group Holdings - Frontier LLC directly holds 22,706,526 shares of Frontier Group Holdings, Inc. common stock, equal to 9.9% of the outstanding shares, with sole power to vote and dispose of them.

Schedules 13D and 13G disclose ownership above 5%; the supplied form description states that Schedule 13G is for passive holders and that amendments track changes in stake or intent as stated.

In this amendment, the LLC reports zero shared voting power and zero shared dispositive power, so the disclosed voting and disposition authority rests solely with the reporting person for the reported stake.

The filing bases the 9.9% ownership figure on 229,789,335 shares outstanding as of May 1, 2026, as reported in the issuer's Form 10-Q filed on May 5, 2026.

beneficially owned financial

"As of the date hereof, Reporting Person directly holds 22,706,526 shares of Common Stock representing 9.9% of the outstanding Common Stock of the Issuer."

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Sole Voting Power financial

"5 | Sole Voting Power 22,706,526.00 6 | Shared Voting Power 0.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

Sole Dispositive Power financial

"7 | Sole Dispositive Power 22,706,526.00 8 | Shared Dispositive Power 0.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

Percent of class financial

"(b) | Percent of class: The Reporting Person may be deemed to be the beneficial owner of the percentage of shares"

Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
