Assumes the vesting of all of the 2,200,000 SEAC Sponsor Options to purchase Pubco Common Shares, each of which, if the following vesting condition is met within 5 years from Closing, will entitle the SEAC Sponsor to purchase one Pubco Common Share for $0.0001 per share. The SEAC Sponsor Options will vest, subject to the terms, conditions and exceptions set forth in the Sponsor Option Agreement, on or after the date on which (i) the Trading Price of the Pubco Common Shares (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) equals or exceeds $16.05 per share or (ii) a change of control occurs, subject to certain conditions.

How will the proceeds from the Business Combination be used by Pubco?

A portion of the Aggregate Transaction Proceeds in the Business Combination will be used by Pubco to pay certain SEAC transaction expenses, which are estimated to be approximately $21 million, and to fund the SEAC Public Warrant Exchange, which is estimated to cost approximately $12.5 million. Any amounts remaining, which are estimated to be between approximately $317 and $374 million, will be paid by a subsidiary of Pubco to a subsidiary of Lions Gate Parent in partial repayment of certain intercompany debt arrangements. See the section entitled “The Business Combination—Sources and Uses for the Business Combination.” See the sections entitled “Risk Factors—Risks Related to the Studio Business—LG Studios

Why is SEAC proposing the Advisory Organizational Documents Proposals?

As required by applicable SEC guidance, SEAC is requesting that the SEAC Shareholders consider and vote upon, on a non-binding advisory basis, proposals to approve the governance provisions contained in the Pubco Closing Articles that materially affect the rights of SEAC Shareholders. These non-binding advisory votes are not otherwise required by either Cayman Islands or British Columbia law and are separate and apart from the Business Combination Proposal, but consistent with SEC guidance, SEAC is submitting these proposals to its shareholders separately as the sub-proposals for approval. Please see the section entitled “Comparison of Corporate Governance and Shareholder Rights” elsewhere in this proxy statement/prospectus for additional information. However, the SEAC Shareholder votes regarding these Proposals are advisory votes and are not binding on the SEAC Board. Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Organizational Documents Proposals.

Did the SEAC Board obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

Yes. The SEAC Board received the Fairness Opinion from Duff & Phelps as to the fairness, from a financial point of view, to the SEAC Shareholders (other than the SEAC Sponsor and its affiliates, the PIPE Investors and any investor who enter into a discounted Non-Redemption Agreement (other than in their capacities as SEAC Shareholders as of the date of the Fairness Opinion), collectively the “Excluded Shareholders”) of the consideration to be received in the Business Combination by such SEAC Shareholders, which opinion was based on and subject to the assumptions made, procedures followed, matters considered and limitations and qualifications set forth in such opinion as more fully described under the subsection “The Business Combination—Opinion of the SEAC Financial Advisor”.

What are some of the positive and negative factors that the SEAC Board and the SEAC Transaction Committee considered when determining to enter into the Business Combination Agreement and their rationale for approving the Business Combination?

The SEAC Transaction Committee and the SEAC Board considered a number of factors pertaining to the Business Combination as generally supporting their respective decisions to enter into the Business Combination Agreement and the transactions contemplated thereby, which are described more fully in the subsection entitled “The Business Combination — The SEAC Transaction Committee and SEAC Board’s Reasons for Approval of the Business Combination”.

Benefits Not Achieved. The risk that the potential benefits of the Business Combination or anticipated performance of StudioCo may not be fully achieved, or may not be achieved within the expected timeframe

and that the results of operations of Pubco’s business may differ materially from the projections prepared by StudioCo and reviewed by the SEAC Transaction Committee and the SEAC Board.

Liquidation of SEAC. The risks and costs to SEAC if the Business Combination is not completed, including the risk of diverting management focus and resources from other businesses combination opportunities, which could result in SEAC being unable to effect an initial business combination within the required timeframe under the SEAC Articles and force SEAC to liquidate and the SEAC Warrants to expire worthless.

Shareholder Vote. The risk that SEAC Shareholders may fail to approve the Business Combination.

Closing Conditions. The fact that completion of the Business Combination is conditioned on the satisfaction of certain closing conditions that are not within the parties’ control.

Litigation. The possibility of litigation challenging the Business Combination or that an adverse judgment granting permanent injunctive relief could indefinitely enjoin consummation of the Business Combination.

Fees and Expenses. The fees and expenses associated with completing the Business Combination.

SEAC Public Shareholders Will Have a Minority Ownership Interest in PubCo. The fact that current SEAC Shareholders will experience immediate dilution as a consequence of the issuance of Pubco Common Shares as consideration in the Business Combination and, as a result, such SEAC Shareholders will collectively own a minority interest in Pubco after the Closing. Having a minority ownership interest may reduce the influence that current SEAC Shareholders have on the management of Pubco.

Other Risks. The various other risks associated with the Business Combination, SEAC’s business and the businesses of StudioCo described in the “Risk Factors” section of this proxy statement/prospectus.

Interests of Certain Persons. The interests of certain of SEAC management in the Business Combination are in addition to, and may be different from, the interests of SEAC Shareholders. The SEAC Transaction Committee and the SEAC Board were aware of these interests during the negotiation of the Business Combination and in evaluating and unanimously approving, as members of the SEAC Transaction Committee and the SEAC Board, the Business Combination Agreement and the Business Combination.

What happens if I sell my SEAC Class A Ordinary Shares before the SEAC Shareholders’ Meeting?

The record date for the SEAC Shareholders’ Meeting is earlier than the date of the SEAC Shareholders’ Meeting and the date that the Business Combination is expected to be completed. If you transfer your SEAC Class A Ordinary Shares after the record date, but before the SEAC Shareholders’ Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the SEAC Shareholders’ Meeting. However, you will not be able to seek redemption of your SEAC Class A Ordinary Shares in accordance with the provisions described in this proxy statement/prospectus. If you transfer your SEAC Class A Ordinary Shares prior to the record date, you will have no right to vote those shares at the SEAC Shareholders’ Meeting or seek redemption of your SEAC Class A Ordinary Shares.

What happens if I sell my SEAC Public Warrants before the SEAC Public Warrantholders’ Meeting?

The record date for the SEAC Public Warrantholders’ Meeting is earlier than the date of the SEAC Public Warrantholders’ Meeting and the date that the Business Combination is expected to be completed. If you transfer your SEAC Public Warrants after the record date, but before the SEAC Public Warrantholders’ Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the SEAC Public Warrantholders’ Meeting.

How has the announcement of the Business Combination affected the trading price of SEAC Units, SEAC Class A Ordinary Shares and SEAC Public Warrants?

On December 21, 2023, the last trading date before the public announcement of the Business Combination, SEAC Units, SEAC Class A Ordinary Shares and SEAC Public Warrants closed at $10.65, $10.56 and $0.10, respectively. On January 4, 2024, the trading date immediately prior to the initial filing date of this proxy statement/prospectus, SEAC Units, SEAC Class A Ordinary Shares and SEAC Public Warrants closed at $10.71, $10.60 and $0.48, respectively. On April 10, 2024, SEAC Units, SEAC Class A Ordinary Shares and SEAC Public Warrants closed at $10.81, $10.71 and $0.48, respectively.

Following the Business Combination, will SEAC’s securities continue to trade on a stock exchange?

No. SEAC, StudioCo and New SEAC anticipate that, following consummation of the Business Combination, the SEAC Class A Ordinary Shares, SEAC Units and SEAC Public Warrants will be delisted from Nasdaq, and SEAC will be deregistered under the Exchange Act. Each SEAC Class A Ordinary Share that is not redeemed by the holder thereof will be, through a series of transactions, exchanged for one Pubco Common Share, as further described under the section titled “What will be the equity stakes of the SEAC Public Shareholders, SEAC Sponsor, Lions Gate Parent and the PIPE Investors in Pubco upon completion of the Business Combination?” In addition, each whole SEAC Public Warrant, subject to the approval of the SEAC Public Warrant Agreement, will be exchanged for $0.50 per warrant in cash and each SEAC Private Placement Warrant will be forfeited.

Why is SEAC proposing the SEAC Warrant Agreement Amendment?

The intent of the SEAC Warrant Agreement Amendment is to reduce the dilutive effect of the presently issued and outstanding SEAC Public Warrants and SEAC Private Placement Warrants to purchase an aggregate of 36,733,333 shares of SEAC Class A Ordinary Shares and to ensure that Lions Gate Parent owns at least 82.5% of Pubco Common Shares upon the Closing.

Who is eligible to vote on the Warrant Agreement Amendment Proposal?

This proxy statement/prospectus and the proxy card are being made available to all persons who were holders of SEAC Public Warrants on April 16, 2024, the record date for voting at the SEAC Public Warrantholders’ Meeting. Such date has been fixed by SEAC for the determination of SEAC Public Warrantholders entitled to vote on the SEAC Warrant Agreement Amendment (as well as the record date for the determination of SEAC Public Warrantholders entitled to vote at the SEAC Public Warrantholders’ Meeting).

What vote is required to approve the Shareholder Proposals presented at the SEAC Shareholders’ Meeting?

Approval of each of the Business Combination Proposal and the SEAC Merger Proposal requires the affirmative vote (in person or by proxy, including by way of the online meeting option) of the holders of not less than two thirds (66 2/3%) of the outstanding SEAC Class A Ordinary Shares and SEAC Class B Ordinary Shares attending (in person or by proxy, including by way of the online meeting option) and entitled to vote at the SEAC Shareholders’ Meeting, voting as a single class. Each of the Advisory Organizational Documents Proposals, the Stock Issuance Proposal and (if put) the Adjournment Proposal require the affirmative vote (in person or by proxy, including by way of the online meeting option) of the holders of a majority of the outstanding SEAC Class A Ordinary Shares and SEAC Class B Ordinary Shares attending (in person or by proxy, including by way of the online meeting option) and entitled to vote at the SEAC Shareholders’ Meeting, voting as a single class. Abstentions, while considered as present for purposes of establishing a quorum, will not count as votes cast at the SEAC Shareholders’ Meeting and therefore will have no effect on any of the Shareholder Proposals (assuming a quorum is present).

What vote is required to approve the Warrantholder Proposals presented at the SEAC Public Warrantholders’ Meeting?

May the SEAC Sponsor, directors, officers, advisors or any of their respective affiliates purchase SEAC Public Shares in connection with the Business Combination?

In connection with the vote of SEAC Shareholders to approve the proposed Business Combination, SEAC Sponsor, SEAC management or SEAC’s advisors and any of their respective affiliates may privately negotiate to purchase SEAC Public Shares from SEAC Public Shareholders who would have otherwise elected to have their shares redeemed in conjunction with a proxy solicitation pursuant to the proxy rules for a per share pro rata portion of the Trust Account. SEAC Sponsor, SEAC management or SEAC’s advisors and any of their respective affiliates will not make any such purchases when they are in possession of any material non-public information not disclosed to the seller of such SEAC Public Shares or during a restricted period under Regulation M under the Exchange Act or other federal securities laws. Such a purchase could include a contractual acknowledgement that such SEAC Shareholder, although still the record holder of such SEAC Public Shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. Any SEAC Public Shares purchased by SEAC Sponsor, SEAC management or SEAC’s advisors or any of their respective affiliates would not be voted in favor of approving the Business Combination. In the event that SEAC Sponsor, SEAC management or SEAC’s advisors or any of their respective affiliates purchase SEAC Public Shares in privately negotiated transactions from SEAC Public Shareholders who have already elected to exercise their redemption rights, such selling shareholders would be required to revoke their prior elections to redeem their shares. In addition, SEAC Sponsor, SEAC management and SEAC’s advisors or any of their respective affiliates would waive any redemption rights with respect to any SEAC Public Shares that they purchase in any such privately negotiated transactions. Any such privately negotiated purchases may be effected at purchase prices that are no higher than the per share pro rata portion of the Trust Account.

How many votes do I have at the SEAC Shareholders’ Meeting?

For all Shareholder Proposals, SEAC Shareholders are entitled to one vote at the SEAC Shareholders’ Meeting for each SEAC Class A Ordinary Share or SEAC Class B Ordinary Share held of record as of April 16, 2024, the record date for the SEAC Shareholders’ Meeting. As of the close of business on the record date, there were 17,175,223 outstanding SEAC Class A Ordinary Shares, which are held by SEAC Public Shareholders, and 18,750,000 outstanding SEAC Class B Ordinary Shares, which are currently held by the SEAC Sponsor.

How many votes do I have at the SEAC Public Warrantholders’ Meeting?

SEAC Public Warrantholders are entitled to one vote at the SEAC Public Warrantholders’ Meeting for each whole SEAC Public Warrant held of record as of April 16, 2024 the record date. As of the close of business on the record date, there were 25,000,000 outstanding SEAC Public Warrants.

Must I pay an exercise price in connection with the warrant exchange?

No. SEAC Public Warrantholders will not be required to pay an exercise price in connection with the warrant exchange or otherwise in connection with the SEAC Warrant Agreement Amendment.

If the SEAC Warrant Agreement Amendment is approved, what will I receive upon consummation of the warrant exchange?

In connection with the Closing, you will receive $0.50 for each whole SEAC Public Warrant you own. Any fractional SEAC Public Warrants will be cancelled for no consideration.

Are there any other conditions to effectiveness of the SEAC Warrant Agreement Amendment?

Yes. Even if the required votes to approve the SEAC Warrant Agreement Amendment are obtained, if the Business Combination Agreement is terminated in accordance with its terms or the consummation of the Business Combination does not occur for any reason, the SEAC Warrant Agreement Amendment will not become effective.

How do I attend the SEAC Shareholders’ Meeting?

The SEAC Shareholders’ Meeting will be held on May 7, 2024, at 10:30 a.m., Eastern Time at the offices of White & Case LLP located at 1221 Avenue of the Americas, New York, New York 10020 and virtually via live webcast at https://www.cstproxy.com/screamingeagleacquisition/2024. pursuant to the procedures described in this proxy statement/prospectus, or such other date, time and place to which such meeting may be adjourned, to consider and vote upon the Shareholder Proposals. All SEAC Shareholders as of the record date, or their duly appointed proxies, may attend the SEAC Shareholders’ Meeting, which will be held both in person and virtually. SEAC Shareholders may attend the SEAC Shareholders’ Meeting online, including to vote and submit questions, at https://www.cstproxy.com/screamingeagleacquisition/2024.

What constitutes a quorum at the SEAC Shareholders’ Meeting?

A quorum will be present at the SEAC Shareholders’ Meeting if the holders of one-third of the SEAC Ordinary Shares being individuals present in person or by proxy or if a corporation or other non-natural person by its duly authorized representative or proxy at the SEAC Shareholders’ Meeting. In the absence of a quorum, the chairman of the meeting has the power to adjourn the SEAC Shareholders’ Meeting. As of the record date for the SEAC Shareholders’ Meeting, 11,975,075 SEAC Ordinary Shares will be required to

What is the Sponsor Securities Repurchase?

Immediately prior to the Class B Conversion, on the business day prior to the Closing Date, each then issued and outstanding SEAC Class B Ordinary Share (and each then issued and outstanding Former SEAC Founder Share) held by the SEAC Sponsor or any of its affiliates or permitted transferees, in excess of 1,800,000 SEAC Class B Ordinary Shares (such 1,800,000 number calculated by including Former SEAC Founder Shares (if any)) (after giving effect to the transfer of 210,000 SEAC Class B Ordinary Shares from the SEAC Sponsor to certain of SEAC’s independent directors, officers or advisors), will be repurchased by SEAC for an aggregate purchase price consisting of (x) $1.00 and (y) 2,200,000 options of SEAC, which will upon the closing of the Business Combination become 2,200,000 Pubco Sponsor Options. Each Pubco Sponsor Option shall entitle the holder to purchase one Pubco Common Share at an exercise price of $0.0001 per share. Each Pubco Sponsor Option will become exercisable, subject to the terms, conditions and exceptions set forth in the Sponsor Option Agreement, on or after the date on which (i) the Trading Price of the Pubco Common Shares (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) equals or exceeds $16.05 per share or (ii) a change of control of Pubco occurs, subject to certain conditions and exceptions. Unless the foregoing vesting condition has previously been met, the Pubco Sponsor Options shall expire and no longer be exercisable on and after the date that is five (5) years after the Closing Date. See the section entitled “The Business Combination Agreement and Related Agreements—Related Agreements—Sponsor Option Agreement.” Assuming no Pubco Common Shares are issued upon exercise of the Pubco Sponsor Options and no additional SEAC Class A Ordinary Shares are purchased by the SEAC Sponsor prior to the Closing, the effective purchase price per share for the 1,800,000 Pubco Common Shares to be held by the SEAC Sponsor at the Closing, after taking account of the SEAC Sponsor Share Reductions in the Business Combination, would be approximately $9.79 based on the SEAC Sponsor’s total investment of $17,625,000. Assuming the exercise of all 2,200,000 Pubco Sponsor Options, the SEAC Sponsor will hold 4,000,000 Pubco Common Shares, which would decrease such effective purchase price per share to approximately $4.41.

How will SEAC Insiders vote?

SEAC Insiders have agreed to vote any SEAC Class A Ordinary Shares (except for any SEAC Class A Ordinary Shares purchased as described above under “May the SEAC Sponsor, directors, officers, advisors or any of their respective affiliates purchase SEAC Public Shares in connection with the Business Combination?” and below under “The Business Combination—Potential Purchases of Public Shares and/or Public Warrants”) and any SEAC Class B Ordinary Shares held by them in favor of the Business Combination. As of the record date, the SEAC Sponsor owns 18,750,000 SEAC Class B Ordinary Shares, which represented approximately 52.2% of the total issued and outstanding SEAC Ordinary Shares, and the other SEAC Insiders own no SEAC Ordinary Shares.

What interests do SEAC’s current officers and directors and the SEAC Sponsor have in the Business Combination?

In considering the unanimous recommendation of the SEAC Transaction Committee and the SEAC Board (other than Harry E. Sloan and Paul Buccieri, each of whom recused himself from consideration and approval of the Business Combination) to vote in favor of the Business Combination, SEAC Shareholders should be aware that, aside from their direct or indirect interests as shareholders, the SEAC Insiders have interests in the Business Combination that are different from, or in addition to, those of other SEAC Shareholders generally. The SEAC Board was aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to SEAC Shareholders that they approve the

Pursuant to the SEAC Articles, the SEAC Sponsor, as the holder of the SEAC Founder Shares, is not entitled to redemption rights with respect to any SEAC Founder Shares and has agreed to waive redemption rights with respect to any SEAC Public Shares held by them in connection with the consummation of the Initial Business Combination. Additionally, SEAC Sponsor is not entitled to redemption rights with respect to any SEAC Founder Shares held by them if SEAC fails to consummate the Initial Business Combination before the Deadline Date. If SEAC does not complete the Initial Business Combination before the Deadline Date, the proceeds of the sale of the SEAC Private Placement Warrants held in the Trust Account will be used to fund the redemption of the SEAC Public Shares, and the SEAC Private Placement Warrants will expire without the receipt of any value by the holders of such warrants. Since SEAC Sponsor and SEAC management directly or indirectly own SEAC Ordinary Shares and SEAC Private Placement Warrants, SEAC management may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate the Initial Business Combination. Pursuant to the Sponsor Support Agreement, SEAC Sponsor has agreed to forfeit the SEAC Private Placement Warrants held by it in connection with the Closing;

The SEAC Sponsor paid an aggregate of approximately $25,000 for the 18,750,000 SEAC Founder Shares (approximately $0.0013 per share, after forfeiture due to there being no exercise of the over-allotment option in the SEAC IPO). The SEAC Sponsor paid an aggregate of approximately $17,600,000 for the 11,733,333 SEAC Private Placement Warrants, at a price of $1.50 per warrant, simultaneously with the consummation of the SEAC IPO. The SEAC Sponsor would lose its entire aggregate investment of $17,625,000 if SEAC does not complete an Initial Business Combination before the Deadline Date. On the contrary, if the Business Combination closes, the Pubco Common Shares held by the SEAC Sponsor and its permitted transferees, after taking into account the SEAC Sponsor Share Reductions, will have a significantly higher value at the time of the Business Combination, which if unrestricted and freely tradable would be valued at approximately $19.3 million, based on the closing price of the SEAC Class A Ordinary Shares of $10.71 per share on April 10, 2024, resulting in a theoretical gain of approximately $1.7 million. Additionally, if, following the Business Combination, the Trading Price of the Pubco Common Shares (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) equals or exceeds $16.05 per share, the SEAC Sponsor will be entitled to receive 2,200,000 Pubco Common Shares upon exercise of the Pubco Sponsor Options at $0.0001 per share, subject to the terms of the Sponsor Option Agreement. Accordingly, assuming a Trading Price of Pubco Common Shares equals $16.05 and the issuance of the full 2,200,000 Pubco Common Shares to the SEAC Sponsor, the aggregate value of the Pubco Common Shares the SEAC Sponsor will hold (assuming no additional purchase of Pubco Common Shares by SEAC), which if unrestricted and freely tradable would be at approximately $64.2 million, resulting in a theoretical gain of approximately $46.6 million;

The fact that given the differential in the purchase price that SEAC Sponsor paid for the SEAC Founder Shares as compared to the price of the SEAC Units sold in the SEAC IPO and the 2,010,000 Pubco Common Shares and the 2,200,000 Pubco Common Shares underlying the Pubco Sponsor Options that the SEAC Sponsor and its permitted transferees will receive upon exchange of the SEAC Founder Shares in connection with the Business Combination, SEAC Sponsor and its permitted transferees may earn a positive rate of return on their investment even if the Pubco Common Shares trade below $10.00, the per share price initially paid for the SEAC Units in the SEAC IPO and the SEAC Public Shareholders experience a negative rate of return following the completion of the Business Combination. After taking into account the SEAC Sponsor Share Reductions, the aggregate market value of the 1,800,000 Pubco Common Shares to be held by the SEAC Sponsor following the Business Combination would be more than the initial investment in SEAC by the SEAC Sponsor if the trading price of the Pubco Common Shares following the Closing is above $9.79 per share;

The fact that certain members of SEAC management, including Harry E. Sloan, Eli Baker and Jeff Sagansky, collectively own, directly or indirectly, a material interest in SEAC Sponsor;

The SEAC Articles provide that SEAC renounces any interest or expectancy in, or in being offered an opportunity to participate in, any potential transaction or matter which may be a corporate opportunity for

any member of SEAC management on the one hand, and SEAC, on the other hand, or the participation of which would breach any existing legal obligation, under applicable law or otherwise, of a member of SEAC management to any other entity. SEAC is not aware of any such corporate opportunities not being offered to SEAC and does not believe that waiver of the corporate opportunities doctrine has materially affected SEAC’s search for an acquisition target or will materially affect SEAC’s ability to complete an Initial Business Combination;

If the Trust Account is liquidated, including in the event SEAC is unable to complete an Initial Business Combination within the required time period, SEAC Sponsor has agreed to indemnify SEAC to ensure that the proceeds in the Trust Account are not reduced below $10.00 per SEAC Public Share, or such lesser amount per SEAC Public Share as is in the Trust Account on the liquidation date, by the claims of (a) any third party (other than SEAC’s independent public accountants) for services rendered or products sold to SEAC or (b) a prospective target business with which SEAC has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement, but only if such a third party or target business has not executed a waiver of all rights to seek access to the Trust Account;

The fact that SEAC Sponsor will benefit from the completion of an Initial Business Combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to SEAC Shareholders rather than liquidate;

The anticipated appointment of Harry E. Sloan, Chairman of the SEAC Board and a director of Lions Gate Parent, as a director on the Pubco Board in connection with the closing of the Business Combination;

The fact that Harry E. Sloan, the Chairman of SEAC, also serves as a member of the board of directors, the compensation committee and the strategic advisory committee of Lions Gate Parent and, as of March 21, 2024, Mr. Sloan beneficially owned 70,101 Class A voting shares of Lions Gate Parent and 271,344 Class B non-voting shares of Lions Gate Parent, each of which represents less than 1% of respective class of shares of Lions Gate Parent. Mr. Sloan also participates in the compensation programs, indemnification and insurance arrangements of Lions Gate Parent applicable to non-employee directors. However, Mr. Sloan has recused himself from the decisions to approve the Business Combination made by both the SEAC Board and board of directors of Lions Gate Parent. Paul Buccieri, a director of SEAC has also recused himself from the decisions to approve the Business Combination made by the SEAC Board due to a potential commercial conflict of interest given his role as President and Chairman of the A+E Networks Group (“A+E Networks”), a company which is also in the media and entertainment industry;

The fact that Pubco will indemnify SEAC Sponsor and its affiliates and their respective present and former directors and officers for a period of six years from the Closing, in connection with any claim, action, suit, proceeding or investigation arising out of or pertaining to the Business Combination and SEAC Sponsor’s ownership of SEAC Securities or its control or ability to influence SEAC;

The fact that the aggregate fees payable to Citi upon the closing of the Business Combination is expected to be approximately $7.6 million, comprising of approximately $3.4 million for its role as co-placement agent, $1.0 million for its role as SEAC’s financial advisor and approximately $3.2 million as the modified deferred underwriting commission to which Citi is entitled equal to a specific percentage of the amount remaining in the Trust Account at Closing, which, for illustrative purposes, is presented here assuming $184.4 million remains in the Trust Account at Closing and after giving effect to redemption rights exercised by the SEAC Public Shareholders and certain other adjustments. (as described in the section “Business of SEAC and Certain Information About SEAC—Modifications to the SEAC IPO Underwriters’ Deferred Discount”);

The fact that the aggregate fees payable to Morgan Stanley upon the closing of the Business Combination is expected to be approximately $6.6 million, comprising of approximately $3.4 million for its role as co-placement agent, and approximately $3.2 million as an incremental fee equal to a specific percentage of the amount remaining in the Trust Account at Closing, which, for illustrative purposes, is presented here assuming $184.4 million remains in the Trust Account at Closing and after giving effect to the redemption rights exercised by the SEAC Public Shareholders and certain other adjustments;

The fact that SEAC has agreed to reimburse Citi and Morgan Stanley, in their capacity as placement agents, for all reasonable and documented expenses of their outside counsel in an amount up to $300,000, to be shared equally between them, incurred in connection with the PIPE, as agreed in their respective engagement letters with SEAC, irrespective of the consummation of the PIPE;

The fact that SEAC has also agreed to reimburse Citi, in its capacity as SEAC’s financial advisor, for all reasonable and documented expenses incurred for its services under its engagement letter with SEAC, including reasonable and documented fees and expenses of Citi’s outside counsel, upon the consummation of the Business Combination, or the expiration or termination of such engagement letter (whichever is earlier); and

Upon the Closing, subject to the terms and conditions of the Business Combination Agreement, the SEAC Insiders, SEAC Board and their respective affiliates may be entitled to reimbursement for any reasonable out-of-pocket expenses related to identifying, investigating and consummating an Initial Business Combination. However, if SEAC fails to consummate an Initial Business Combination, such persons will not have any claim against the Trust Account for reimbursement and SEAC may not be able to reimburse these expenses. No such reimbursable out-of-pocket expenses have been provided to SEAC for reimbursement as of the date of this proxy statement/prospectus.

Are there material differences between my rights as a Pubco Shareholder and my rights as a SEAC Shareholder?

Yes. There are certain material differences between your rights as a Pubco Shareholder and your rights as a SEAC Shareholder. You are urged to read the sections entitled “Description of Pubco Securities” and “Comparison of Corporate Governance and Shareholder Rights”.

What happens if I vote against the Business Combination Proposal?

Under the SEAC Articles, if the Business Combination Proposal is not approved and SEAC does not otherwise consummate an alternative business combination by the Deadline Date, SEAC will be required to dissolve and liquidate the Trust Account by returning the then-remaining funds in such account to SEAC Public Shareholders.

Do I have redemption rights?

Pursuant to the SEAC Articles, a SEAC Public Shareholder may request that SEAC redeem all or a portion of its SEAC Public Shares for cash if the Business Combination is consummated. As a SEAC Public Shareholder, you will be entitled to exercise your redemption rights if you:

hold SEAC Public Shares or, if you hold SEAC Public Shares through SEAC Units, you elect to separate your SEAC Units into the underlying SEAC Public Shares and SEAC Public Warrants prior to exercising your redemption rights;

submit a written request to Continental Stock Transfer & Trust Company, the Transfer Agent, in which you (i) request the exercise of your redemption rights with respect to all or a portion of your SEAC Public Shares for cash and (ii) identify yourself as the beneficial holder of the SEAC Public Shares and provide your legal name, phone number and address; and

deliver your SEAC Public Shares to the Transfer Agent, physically or electronically through DTC.

Will how I vote affect my ability to exercise redemption rights?

No. You may exercise your redemption rights whether you vote your SEAC Class A Ordinary Shares for or against or abstain from voting on the Business Combination Proposal or any other Shareholder Proposal described in this proxy statement/prospectus. As a result, the Business Combination can be approved by SEAC Public Shareholders who will redeem their shares and no longer remain SEAC Shareholders.

How do I exercise my redemption rights?

In order to exercise your redemption rights, you must (a) if you hold SEAC Units, elect to separate your SEAC Units into the underlying SEAC Public Shares and SEAC Public Warrants prior to exercising your redemption rights with respect to the SEAC Public Shares; and (b) prior to 12:00 p.m., Eastern Time, on May 3, 2024 (two business days prior to scheduled date of the SEAC Shareholders’ Meeting), tender your shares physically or electronically and submit a written request to Continental Stock Transfer & Trust Company, the Transfer Agent, in which you (i) request the exercise of your redemption rights with respect to all or a portion of your SEAC Public Shares for cash, and (ii) identify yourself as the beneficial holder of the SEAC Public Shares and provide your legal name, phone number and address, at the following address:

What are the material U.S. federal income tax consequences to the SEAC Shareholders that are U.S. Holders as a result of the SEAC Merger, the New SEAC Domestication, the SEAC Amalgamation and StudioCo Amalgamation?

As discussed more fully below in the section entitled “Material U.S. Federal Income Tax Considerations for U.S. Holders,” the parties intend that (i) the SEAC Merger and the New SEAC Domestication each qualify as a “reorganization” within the meaning of Section 368(a)(1)(F) of the Code (an “F Reorganization”) and (ii) the exchange by U.S. Holders (as defined below in the section entitled “Material U.S. Federal Income Tax Considerations for U.S. Holders”) of their New SEAC Class A Common Shares held immediately prior to the StudioCo Amalgamation for Pubco Common Shares pursuant to the StudioCo Amalgamation qualify as a tax-deferred exchange, either as a “reorganization” within the meaning of Section 368(a)(1)(E) of the Code or an exchange under Section 1036 of the Code, or, alternatively, is a disregarded transaction and not a realization event. Subject to the PFIC rules discussed under the section entitled “Material U.S. Federal Income Tax Considerations for U.S. Holders —VII. Passive Foreign Investment Company Considerations,” if the SEAC Merger, the New SEAC Domestication and the StudioCo Amalgamation so qualify, the SEAC Shareholders that are U.S. Holders generally are not expected to recognize gain or loss for U.S. federal income tax purposes in connection with the SEAC Merger, the New SEAC Domestication or the StudioCo Amalgamation, as applicable. In addition, while not free from doubt, SEAC Shareholders that are U.S. Holders generally are not expected to have any U.S. federal income tax consequences as a result of the SEAC Amalgamation.

What are the U.S. federal income tax consequences of exercising my redemption rights if I am a U.S. Holder?

The U.S. federal income tax consequences of exercising your redemption rights with respect to your SEAC Public Shares depend on your particular facts and circumstances. It is possible that you may be treated as selling your SEAC Public Shares for U.S. federal income tax purposes and, as a result, recognize capital gain or capital loss. It is also possible that the redemption may be treated as a distribution for U.S. federal income tax purposes. Whether a redemption of SEAC Public Shares qualifies for sale treatment will depend

What are the U.S. federal income tax consequences of the SEAC Warrant Agreement Amendment if I am a U.S. Holder?

The exchange of SEAC Public Warrants for cash in connection with the SEAC Warrant Agreement Amendment generally will be treated as a taxable sale of the SEAC Public Warrants by a U.S. Holder for cash for U.S. federal income tax purposes. For a more complete discussion of the U.S. federal income tax considerations of the SEAC Warrant Agreement Amendment for U.S. Holders, including the applicability and effect of the PFIC rules, see “Material U.S. Federal Income Tax Considerations for U.S. Holders.”

If I am a SEAC Warrant Holder, can I exercise redemption rights with respect to my SEAC Warrants?

No. SEAC Warrant Holders have no redemption rights with respect to SEAC Warrants.

Do I have appraisal or dissent rights if I object to the proposed Business Combination?

Pursuant to the Interim Order, no dissent rights are available to SEAC Shareholders under the corporate law of British Columbia in connection with the Business Combination nor are appraisal rights available to holders of SEAC Class A Ordinary Shares and SEAC Class B Ordinary Shares in connection with the Business Combination. Under the Companies Act, minority shareholders have a right to dissent to a merger and if they so dissent, they are entitled to be paid the fair market value of their shares, which if necessary, may ultimately be determined by the court. Therefore, SEAC Shareholders have a right to dissent to the SEAC Merger. In addition, SEAC Shareholders are entitled to exercise the rights of redemption as set out in the subsection entitled “Extraordinary General Meetings of SEAC Shareholders and SEAC Public Warrantholders—Redemption Rights” and the SEAC Board has determined that the redemption proceeds payable to SEAC Shareholders who exercise such redemption rights represents the fair value of those SEAC Ordinary Shares. Please see the subsection entitled “Extraordinary General Meetings of SEAC Shareholders and SEAC Public Warrantholders—Appraisal or Dissent Rights” for more information.

What happens to the funds deposited in the Trust Account after consummation of the Business Combination?

If the Business Combination Proposals are approved, SEAC intends to use a portion of the funds held in the Trust Account to pay for any redemptions of SEAC Public Shares. The remaining balance in the Trust Account following the payment of the foregoing will be used to pay (i) the purchase price of the SEAC

What happens if the Business Combination is not consummated or is terminated?

There are certain circumstances under which the Business Combination Agreement may be terminated. See the subsection entitled “The Business Combination Agreement and Related Agreements—Termination” for additional information regarding the parties’ specific termination rights. In accordance with the SEAC Articles, if an Initial Business Combination is not consummated by the Deadline Date, SEAC will (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not more than ten business days thereafter, redeem the SEAC Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to SEAC (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish SEAC Public Shareholders’ rights as SEAC Shareholders (including the right to receive further liquidation distributions, if any), and (c) as promptly as reasonably possible following such redemption, subject to the approval of SEAC’s remaining SEAC Shareholders and the SEAC Board, liquidate and dissolve, subject in each case to SEAC’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law.

When is the Business Combination expected to be consummated?

It is currently anticipated that the Business Combination will be consummated promptly following the SEAC Meetings to be held on May 7, 2024 provided that all the requisite approvals by SEAC Shareholders and SEAC Public Warrantholders are obtained and other conditions to the consummation of the Business Combination have been satisfied or waived. For a description of the conditions to the completion of the Business Combination, see the subsection entitled “The Business Combination—Conditions to Closing of the Business Combination”.

What is StudioCo?

StudioCo is LG Orion Holdings ULC, a British Columbia unlimited liability company. StudioCo exists for the purpose of holding Lions Gate Parent’s Studio Business and amalgamating with New SEAC in connection with the transactions described in this proxy statement/prospectus.

What will SEAC Public Warrantholders receive in the Business Combination?

Assuming the Warrant Agreement Amendment Proposal is approved by the SEAC Public Warrantholders, immediately following the Unit Separation and prior to the SEAC Merger, each of the then issued and outstanding whole SEAC Public Warrants will be automatically exchanged for $0.50 per whole SEAC Public Warrant in accordance with the terms of the SEAC Warrant Agreement Amendment, substantially in the form attached as Annex F hereto. Any fractional SEAC Public Warrants will be cancelled for no consideration. In accordance with the terms of the Warrantholder Support Agreements, the SEAC Warrant Support Investors agreed to vote in favor of the SEAC Warrant Agreement Amendment at the SEAC Public Warrantholders’ Meeting. Approval of the SEAC Warrant Agreement Amendment requires the vote of the registered holders of fifty percent (50%) of the number of the then outstanding SEAC Public Warrants. Pursuant to the terms of the Sponsor Support Agreement, no later than the Warrant Re-Purchase Cut-Off Date, SEAC Sponsor agreed to purchase, or cause its affiliates to purchase in the open market, in the aggregate, no less than 5.81% of the outstanding SEAC Public Warrants. If the SEAC Sponsor fails to complete the Purchase Obligation, then SEAC Sponsor shall irrevocably surrender and forfeit, and SEAC shall cause any applicable SEAC Entity (as defined herein) to extinguish and cancel an amount of Pubco Common Shares delivered to SEAC Sponsor at the Closing equivalent in value to the SEAC Public Warrant Cutback Amount. In addition, pursuant to the terms of the Sponsor Support Agreement, SEAC Sponsor agreed to forfeit all of the outstanding SEAC Private Placement Warrants immediately prior to the SEAC Merger Effective Time. As a result, no SEAC Warrants will be issued or outstanding as of the Closing.

What will SEAC Unitholders receive in the Business Combination?

To the extent any SEAC Units remain outstanding and unseparated, immediately prior to the SEAC Merger Effective Time, the SEAC Class A Ordinary Shares and SEAC Warrants comprising each such issued and outstanding SEAC Unit immediately prior to the SEAC Merger Effective Time will be automatically separated, and the holder of each SEAC Unit will be deemed to hold one SEAC Class A Ordinary Share and one-third (1/3) of one SEAC Public Warrant. The SEAC Class A Ordinary Shares and SEAC Public Warrants held following the Unit Separation will be converted or redeemed for cash as described above in accordance with the Business Combination Agreement.

What will SEAC Public Shareholders receive in the Business Combination?

SEAC Public Shareholders who do not redeem their SEAC Class A Ordinary Shares will ultimately (as a result of the SEAC Merger and the Amalgamations) receive one (1) Pubco Common Share for each SEAC Class A Ordinary Share held by them immediately prior to the SEAC Merger.

What do I need to do now?

You are urged to read carefully and consider the information contained in this proxy statement/prospectus, including the section entitled “Risk Factors” and the annexes attached to this proxy statement/prospectus, and to consider how the Business Combination will affect you as a shareholder. You should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy card or, if you hold your shares through a brokerage firm, bank or other nominee, on the voting instruction form provided by the broker, bank or nominee.

How do I vote?

If you are a shareholder and/or warrantholder of record, there are two ways to vote your SEAC Class A Ordinary Shares, SEAC Class B Ordinary Shares, and/or SEAC Public Warrants at the SEAC Shareholders’

What will happen if I abstain from voting or fail to vote at the SEAC Meetings?

At the SEAC Meetings, a properly executed proxy marked “ABSTAIN” with respect to a particular Shareholder Proposal will count as present for purposes of determining whether a quorum is present.

What will happen if I sign and submit my proxy card without indicating how I wish to vote?

Signed and dated proxies received by SEAC without an indication of how the SEAC Shareholder and/or SEAC Public Warrantholder intends to vote on a Proposal will be voted “FOR” each Proposal being submitted to a vote of the SEAC Shareholders and/or SEAC Public Warrantholders at the SEAC Meetings.

If I am not going to attend the SEAC Meetings, should I submit my proxy card instead?

Yes. Whether you plan to attend the SEAC Meetings or not, please read this proxy statement/prospectus carefully, and vote your SEAC Ordinary Shares and/or SEAC Public Warrants by completing, signing, dating, and returning the enclosed proxy card in the postage-paid envelope provided.

If my SEAC Ordinary Shares and/or SEAC Public Warrants are held in “street name,” will my broker, bank or nominee automatically vote my shares/warrants for me?

No. Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your SEAC Ordinary Shares or SEAC Public Warrants with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee. SEAC believes the Proposals presented to SEAC Shareholders and SEAC Public Warrantholders will be considered non-discretionary and therefore your broker, bank, or nominee cannot vote your SEAC Ordinary Shares or SEAC Public Warrants without your instruction. Your bank, broker, or other nominee can vote your SEAC Ordinary Shares and/or SEAC Public Warrants only if you provide instructions on how to vote. You should instruct your broker to vote your SEAC Ordinary Shares and/or SEAC Public Warrants in accordance with directions you provide.

May I change my vote after I have submitted my executed proxy card?

Yes. You may change your vote by sending a later-dated, signed proxy card to SEAC at the address listed below so that it is received by SEAC prior to the SEAC Meetings or by attending the applicable SEAC Meeting in person or online and voting there. You also may revoke your proxy by sending a notice of revocation to SEAC, which must be received prior to the SEAC Meetings.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction forms. For example, if you hold your SEAC Securities in more than one brokerage account, you will receive a separate voting instruction form for each brokerage account in which you hold SEAC Securities. If you are a holder of record and your SEAC Securities are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date, and return each proxy card and voting instruction form that you receive in order to cast your vote with respect to all of your SEAC Securities.

Who can help answer my questions?

If you have questions about the Proposals or if you need additional copies of the proxy statement/prospectus or the enclosed proxy card you should contact:
