Greystone Capital Management Increases Stake in Shift4 Payments

Greystone Capital Management identified Shift4 Payments, Inc. as a compelling investment in its second-quarter 2026 investor letter. The investment firm has been adding to its position in the payment processing company despite a 22% year-to-date decline in share price and a 48.14% drop over the previous 52 weeks.

Greystone attributes the stock's downward trend to general negative sentiment toward payments-related equities and weaker 2026 guidance, which included slower growth and headwinds within the tax-free shopping sector. However, the firm maintains that Shift4 Payments remains undervalued.

According to Greystone, the company's value is supported by its integrated payments exposure, vertical software products, and its capacity to cross-sell to acquired customer bases. The firm also noted that an incremental free cash flow conversion of approximately 60% should drive annual total free cash flow improvements as EBITDA grows.
