Preliminary Prospectus

20,500,000 Shares

Common Stock

BDT Capital Partners, LLC (“BDTCP”) and its affiliated investment funds (collectively, our “principal stockholder”), are selling shares of our common stock in this offering. Our principal stockholder is an affiliate of BDT & MSD Partners, LLC (“BDT & MSD”), one of the underwriters in this offering.

We intend to purchase from the underwriters shares of our common stock at a price per share equal to the price per share at which the underwriters will purchase shares of our common stock from the principal stockholder for an aggregate repurchase price of approximately $75 million (the “Share Repurchase”). The underwriters will not receive any compensation for the shares of our common stock being repurchased by us. The completion of the Share Repurchase is conditioned upon the completion of this offering.

Our common stock trades on the New York Stock Exchange (“NYSE”) under the symbol “ALH.” On August 14, 2026, the closing price of our common stock as reported on the NYSE was $25.47 per share.

After the consummation of this offering and the Share Repurchase, we expect to continue to be a “controlled company” within the meaning of the corporate governance standards of the NYSE.

Investing in our common stock involves risk. See “Risk Factors” beginning on page 16 of this prospectus and the risk factors in the documents incorporated by reference herein to read about factors you should consider before buying shares of our common stock.

This is a firm commitment underwritten offering. The underwriters may also exercise their option to purchase up to an additional 3,075,000 shares from our principal stockholder, at the public offering price, less the underwriting discount, for 30 days after the date of this prospectus to cover sales of additional shares by the underwriters. We will not receive any proceeds from the sale of our common stock pursuant to any exercise of the underwriters’ option to purchase additional shares.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Delivery of the shares of common stock will be made on or about , 2026.
