Haymaker Acquisition Corp. 4 enters non-redemption agreements for business combination

Haymaker Acquisition Corp. 4 entered non-redemption agreements covering 4,442,085 Class A shares, with participating investors waiving redemption rights and abstaining from voting to facilitate the business combination with Suncrete and Concrete Partners. Haymaker expects net proceeds of approximately $10.75 per non-redeemed public share after fees, and, together with a previously announced $105.5M PIPE, the parties anticipate meeting the minimum cash condition at close. Suncrete will pay selling shareholders the difference between the actual redemption price and the sale price to the investors. Securities trade under NYSE:HYAC / HYACU / HYAC WS.

Analysis

Market action reflects an increased perceived probability that this SPAC transaction will clear near-term financing and vote hurdles; that re-pricing is concentrated in equity/units while warrants still embed residual binary risk. The immediate arbitrage is therefore directional rather than pure risk-free merger arb — investors are buying optionality on a close while the capital structure still carries execution and dilution risk.

A less-obvious second-order is governance and float dynamics post-close: arrangements that shore up near-term financing typically concentrate decision rights and can increase immediate free float as legacy holders trade into liquidity, which compresses a short-run takeover premium but raises headline volatility. That combination tends to favor instruments with convex payoffs (warrants/calls) for upside capture while making straight equity more exposed to large downside on deal failure.

Key catalysts and risks cluster on the financing and vote windows over the next 30–90 days; a confirmed PIPE funding and an uncontested vote will likely compress spreads quickly, whereas any renegotiation, regulatory pushback, or sponsor cash-top-up would widen them again. Position sizing should assume binary downside to zero on failure and slower-than-expected operational upside post-close; monitor new insider/affiliate selling, warrant implied vol, and any legal disclosures that change sponsor economics as primary early-warning signals.

Key Decisions for Investors

• Tactical long HYAC (shares/units) 1–3 month trade: size 0.5–2% NAV. Rationale: capture convergence if vote and financing complete; hedge with a 6–12 month put or buy a put spread to cap downside (cost ~1–3% NAV). Risk/Reward: potential 20–40% upside on close vs near-total loss on failure — keep position size small.
• Leveraged optionality via HYAC WS (warrants) 3–12 month: allocate 0.25–0.75% NAV as a lottery ticket on successful close. Rationale: warrants asymmetrically benefit from deal completion with limited cash exposure; expect higher theta and VIX sensitivity. Risk/Reward: high upside if close; worthless if liquidation — keep conviction sizing tiny.
• Merger-arb pair to isolate deal risk: long HYAC equity / short a broad SPAC ETF or a comparable SPAC with weaker financing prospects for 1–3 months. Rationale: removes market beta and targets deal-specific rerating. Risk/Reward: reduces macro exposure; residual idiosyncratic deal failure remains.
• Protective hedge: if holding HYAC longer term, buy 9–12 month put spreads to limit drawdown while retaining upside to post-close operational value. Rationale: insulates portfolio from binary outcome while allowing participation in integration upside. Risk/Reward: modest cost for meaningful tail protection.
