Executive Summary

Plains All American Pipeline is issuing two series of junior subordinated notes due 2056 (Series A and Series B) in an underwritten public offering. The net proceeds, combined with cash on hand and commercial paper borrowings, will be used to redeem all outstanding Series A Preferred Units (58,411,908 units at 110% of $26.25 par) and all 800,000 Series B Preferred Units (at 100% of $1,000 par). This is a refinancing transaction that replaces higher-cost preferred equity with lower-cost, tax-deductible junior subordinated debt, improving the capital structure and reducing the cost of capital for common unitholders. The offering is credit-positive for the common equity as it eliminates a high-cost preferred dividend burden and simplifies the capital stack.

Key Facts

• Plains is offering two series of junior subordinated notes due 2056: Series A and Series B.
• Net proceeds will redeem all 58,411,908 Series A Preferred Units at 110% of $26.25 par and all 800,000 Series B Preferred Units at 100% of $1,000 par.
• The Series A Preferred Units carried a 9.375% annual distribution rate; the Series B Preferred Units carried a floating rate based on 3-month SOFR + 4.37161%.
• The new notes are junior subordinated debt, ranking below all senior indebtedness but pari passu with future unsecured debt of equal rank.
• The notes have a 30-year maturity (2056) with an optional interest deferral feature of up to 10 years.
• The offering is underwritten by J.P. Morgan, Citigroup, Mizuho, MUFG, and Truist Securities.

• The company completed the EPIC Crude Holdings acquisition in late 2025 and sold its Canadian NGL business in May 2026.

Financial Impact

Redemption of ~$1.53B in Series A Preferred (58.4M units x $26.25 x 110%) and $800M in Series B Preferred (800K units x $1,000 x 100%), totaling approximately $2.33B in preferred equity retired, replaced with junior subordinated notes at a lower after-tax cost.

Risk Factors

• The notes are subordinated to all senior debt, meaning in a liquidation preferred holders would recover less than senior creditors.
• The optional interest deferral feature (up to 10 years) could create uncertainty for noteholders and may affect the market price of the notes.
• The offering size and final interest rates are not yet determined, which could affect the economics of the refinancing.
• PAA's significant leverage ($8.4B in long-term debt) could limit future financial flexibility.
