BlackRock Debt Strategies Fund, Inc. is offering up to 30,000,000 common shares through an at-the-market program, with UBS Securities LLC acting as sub-placement agent under a distribution agreement with an affiliated BlackRock distributor.
The shares must be sold at prices at or above current net asset value (NAV) plus selling commissions. As of February 3, 2026, NAV was $10.00 per share and the NYSE market price was $10.18, a 1.80% premium. Assuming all shares are sold at $10.18, the Fund estimates net proceeds of about $302,142,215 after a 1.00% sales load and offering costs.
The Fund intends to invest net proceeds in line with its strategy of holding primarily below‑investment‑grade corporate loans and other debt, aiming to deploy capital within roughly three to six months. Pending deployment, proceeds may be placed in short-term investment grade or money market instruments and may also help fund the Fund’s level monthly distribution policy, which can include return of capital.
