Boost Run Inc. filed an amended S-4 registration statement on March 27, 2026 for its proposed business combination with Willow Lane Acquisition Corp., a Cayman Islands blank check company. The transaction contemplates a two-step merger whereby Willow Lane will re-domicile to Delaware and merge with Boost Run, with Pubco (Boost Run Inc.) becoming the publicly traded parent company. Boost Run shareholders will receive consideration including an $8.5 million installment note to Andrew Karos and $441.5 million in newly issued Pubco common stock divided by $10.00 per share.
