Rhea-AI Filing Summary

Catalyst Sponsor LLC, the sponsor of Catalyst Acquisition Corp., reports beneficial ownership of 6,020,000 Ordinary Shares, representing 22.2% of the company’s 27,170,000 outstanding Ordinary Shares (21,420,000 Class A and 5,750,000 Class B as of August 4, 2026). The position comprises 270,000 Class A shares held via private placement units and 5,750,000 Class B Founder Shares, which are automatically convertible into Class A shares on a one-for-one basis in connection with the initial business combination. Up to 462,500 of these Class B shares are subject to forfeiture if the IPO underwriter does not fully exercise its over-allotment option.

The Sponsor acquired its stake for an aggregate purchase price of $2,725,000, including $25,000 for 8,625,000 Founder Shares (later reduced to 5,750,000 after surrender of 2,875,000 shares) and $10.00 per unit for 270,000 placement units bought at the July 27, 2026 IPO. The Sponsor has agreed to vote its shares in favor of any proposed business combination, not redeem its shares in related votes, accept lock-up restrictions on the private placement securities, and provide certain indemnities and registration rights, consistent with typical SPAC sponsor arrangements.

Filing Explained

Sponsor-held rights could add 38,571 Class A shares only at an initial business combination; those shares are not part of its current 22.2% stake.

This Schedule 13D, signed on 2026-08-05 for a 2026-07-29 event, records the sponsor's 22.2% beneficial ownership; the filing discusses a future business combination rather than reporting one as completed.

The sponsor's 270,000 rights are excluded from that stake, but the filing says they would produce 38,571 Class A shares upon consummation of the initial business combination, increasing the share count and reducing existing ownership percentages absent offsetting changes.

The insider letter also provides that the sponsor's Founder Shares and shares underlying its placement units will not participate in a liquidating distribution if no business combination is completed, so those sponsor-held securities have a different liquidation entitlement from public shares.

The platform lists a Schedule 13G dated 2026-08-04, while this page is a Schedule 13D. Schedules 13D and 13G disclose ownership above 5%; the supplied definition associates Schedule 13D with a holder that may seek to influence control. In this filing, the sponsor says it has no plans or proposals on the listed matters other than the business-combination arrangements, while reserving the ability to review or change its position.

The initial business combination is the named milestone for determining whether the excluded rights convert into the additional Class A shares.

Founder Shares financial
"paid $25,000 to cover certain of the Issuer's offering costs in exchange for 8,625,000 Founder Shares"
Founder shares are the ownership stakes given to the people who start a company, often with extra voting power or protections compared with ordinary shares. For investors, they matter because founders’ control and incentives influence decisions about strategy, hiring, and whether the company sells or stays independent — like a family that keeps majority voting rights in a household decision. High founder ownership can mean stable leadership but also a risk that outside shareholders have less influence.
Placement Units financial
"the Sponsor purchased 270,000 units ("Placement Units") of the Issuer at $10.00 per Placement Unit"
over-allotment option financial
"subject to forfeiture in the event that the underwriter in the Issuer's initial public offering does not fully exercise its over-allotment option"
An over-allotment option is a special agreement that allows underwriters to sell more shares than initially planned if demand is high. Think of it like a retailer offering extra units of a popular product to meet additional customer interest. This option helps ensure the full sale is completed and can also give investors extra shares if they want more.
Trust Account financial
"the Issuer's trust account set up in connection with the IPO (the "Trust Account")"
A trust account is a special bank or brokerage account where assets are held and managed by a designated person or firm (the trustee) for the benefit of another person or group (the beneficiary). It matters to investors because it separates assets from personal or corporate funds, can protect assets, control how and when money is used, and may affect tax or legal rights—think of it as a locked drawer opened only under agreed rules.
registration rights agreement financial
"entered into a registration rights agreement with the Issuer, pursuant to which the Sponsor was granted certain demand and "piggyback" registration rights"
A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.
blank check company regulatory
"the Issuer is a blank check company formed for the purpose of effecting a merger"
A blank check company is a publicly listed shell that raises money from investors before naming a specific business to buy or merge with, similar to handing a cashier a signed check and asking them to fill in the payee later. It matters to investors because it offers a faster, often cheaper path for private firms to become public, but carries extra risk since returns depend on the organizers’ ability to find a good deal and on limited information about the future business.
