• Option symbols switch from WLAC/1WLAC to BRUN/1BRUN
• Strike prices and terms remain unchanged
• Contract multiplier updates to 100 shares per contract

Pulse Analysis

The OCC’s memorandum confirms that Willow Lane Acquisition Corp., a special purpose acquisition company, will rebrand as Boost Run Inc. after consummating its merger. The new CUSIP 09940T100 and ticker BRUN will debut on May 11, 2026, aligning the public listing with the combined entity’s operating business. Such name and symbol changes are routine in SPAC completions, but they require precise coordination across exchanges, data vendors, and brokerage platforms to ensure market participants see the correct identifiers.

For options market participants, the most visible change is the transition from WLAC/1WLAC to BRUN/1BRUN. While strike prices, expiration dates and contract terms stay the same, the contract multiplier will shift from 1 to 100, meaning each options contract now represents 100 Boost Run Class A shares. This adjustment impacts margin calculations, position sizing, and the physical delivery process. Clearing members must update their OCC input files immediately to avoid mismatches that could trigger settlement failures or erroneous trade confirmations.

Beyond the operational tweaks, the ticker change signals Boost Run’s entry into the public arena, potentially widening its investor base and liquidity. Traders should verify that their order management systems, risk models, and reporting tools reflect the new identifiers before the effective date. The OCC’s guidance underscores the importance of timely communication between issuers, clearing houses, and market participants to preserve market integrity during corporate events of this nature.

Deal Summary

Willow Lane Acquisition Corp. announced it will complete a business combination with Boost Run Inc., resulting in a name change to Boost Run Inc. and a new ticker symbol BRUN effective May 11, 2026.
