What investment stages does Loomis, Sayles typically target?

Loomis, Sayles focuses primarily on liquid public fixed-income markets (investment-grade and high-yield bonds) and extends into private credit, infrastructure debt, and real estate equity. The firm targets mature, cash-flow generating assets rather than early-stage venture investments.

Which sectors does Loomis, Sayles explicitly avoid?

The firm does not have a public list of excluded sectors, but its core credit focus means it predominantly lends to established, creditworthy entities across industrials, utilities, financials, and infrastructure. It does not typically invest in venture-stage technology or speculative biotech.
