Q1 2023 3 "First quarter normalized FFO of $0.05 per share represented an improvement of over $34 million from the prior year. These results reflected continued improvement in our SHOP segment, where net operating income increased over $17 million from the prior year and over $9 million from the fourth quarter of 2022. While we are encouraged to see the turnaround of the SHOP segment begin to materialize, the recovery has not occurred fast enough for DHC to overcome its near-term challenges and refinance the $700 million of debt maturing within the next year. In April, we announced our plan to merge with Office Properties Income Trust. Upon closing, we believe that the combined company will be in compliance with all of its debt covenants. It is also expected to have access to multiple capital sources to fund upcoming debt maturities and continue to invest in the senior living portfolio to contribute to the recovery that is underway. DHC shareholders will benefit in a number of ways from this transaction, including a dividend increase of over 267%."
