All financial information contained in this supplemental information package is unaudited.  In addition, certain statements contained in this supplemental information package may be deemed to be forward-looking statements within the meaning of the federal securities laws.  Although FSP believes that the expectations reflected in such forward-looking statements are based upon reasonable assumptions, it can give no assurance that its expectations will be achieved.  Factors that could cause actual results to differ materially from FSP’s current expectations include adverse changes in general economic or local market conditions, including as a result of geopolitical events, the long-term effects of the COVID-19 pandemic and wars, terrorist attacks or other acts of violence, which may negatively affect the markets in which we and our tenants operate, the effects of changes in tariffs and trade policies, inflation rates, interest rates, disruptions in the debt markets, economic conditions in the markets in which we own properties, risks of a lessening of demand for the types of real estate owned by us, adverse changes in energy prices, which if sustained, could negatively impact occupancy and rental rates in the markets in which we own properties, including energy-influenced markets such as Dallas, Denver and Houston, changes in government regulations and regulatory uncertainty, uncertainty about governmental fiscal and trade policy and expenditures that cannot be anticipated such as utility rate and usage increases, delays in construction schedules, unanticipated increases in construction costs, unanticipated repairs, additional staffing, insurance increases and real estate tax valuation reassessments.  FSP assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.

● The table above is a summary of our debt as of June 30, 2025.  Additional information on our debt can be found in our Annual Report on Form 10-K for the year ended December 31, 2024, which may be updated in our future Quarterly Reports on Form 10-Q, on file with the U.S. Securities and Exchange Commission.  

● On February 21, 2024, we entered into an amendment to the credit agreement evidencing our BMO Term Loan Tranche B.  On February 21, 2024, as part of the amendment to the credit agreement, we repaid a $29.0 million portion of the BMO Term Loan, so that $86.0 million of the principal amount remained outstanding.  The amendment, among other items, extended the maturity date from October 1, 2024 to April 1, 2026.  

● On February 21, 2024, we entered into an amendment to the credit agreement evidencing our BofA Revolver.  On February 21, 2024, as part of the amendment to the revolving line of credit agreement, we repaid a $22.7 million portion of the $90 million then outstanding, so that $67.3 million of the principal amount remained outstanding.  The amendment, among other items, extended the maturity date from October 1, 2024 to April 1, 2026 and converted the revolving loan to a term loan.  

● On February 21, 2024, we entered into an amendment to the note purchase agreement evidencing our $200 million of Senior Notes.  On February 21, 2024, as part of the amendment to the note purchase agreement, we repaid a $29.2 million portion of the Series A Notes, so that $86.8 million of the principal amount remained outstanding.  On February 21, 2024, as part of the amendment to the note purchase agreement, we repaid a $21.2 million portion of the Series B Notes, so that $62.8 million of the principal amount remained outstanding. The amendment, among other items, changed the maturity date applicable to the Series A Notes from December 20, 2024 to April 1, 2026, and changed the maturity date applicable to the Series B Notes from December 20, 2027 to April 1, 2026.  

● On July 8, 2024, we sold a property located in Glen Allen, Virginia for a gross sales price of $31 million, and on July 10, 2024, we used approximately $25.5 million of net proceeds to repay our outstanding debt pari passu based on principal amounts then outstanding.    

● On October 23, 2024, we sold a property located in Atlanta, Georgia for a gross selling price of $34 million, and on October 25, 2024, we used approximately $27.4 million of net proceeds to repay our outstanding debt pari passu based on principal amounts then outstanding.  

● On March 4, 2025 and May 14, 2025, we received escrows in the aggregate of $0.6 million that were held from the sale of two properties and used approximately $0.5 million to repay our outstanding debt pari passu based on principal amounts then outstanding, resulting in the debt that remains outstanding included in the table above.  

● We incurred financing costs, some of which are deferred and amortized into interest expense during the terms of the loans we execute.  We estimate the future annualized amount of the amortization included in interest expense will be approximately $2.7 million.  

(a) Interest rates exclude amortization of deferred financing costs.

Appendix: Non-GAAP Financial Measure Definitions

Definition of Funds From Operations (“FFO”)

The Company evaluates performance based on Funds From Operations, which we refer to as FFO, as management believes that FFO represents the most accurate measure of activity and is the basis for distributions paid to equity holders.  The Company defines FFO as net income or loss (computed in accordance with GAAP), excluding gains (or losses) from sales of property, hedge ineffectiveness, acquisition costs of newly acquired properties that are not capitalized and lease acquisition costs that are not capitalized plus depreciation and amortization, including amortization of acquired above and below market lease intangibles and impairment charges on mortgage loans, properties or investments in non-consolidated REITs, and after adjustments to exclude equity in income or losses from, and, to include the proportionate share of FFO from, non-consolidated REITs.  

FFO should not be considered as an alternative to net income or loss (determined in accordance with GAAP), nor as an indicator of the Company’s financial performance, nor as an alternative to cash flows from operating activities (determined in accordance with GAAP), nor as a measure of the Company’s liquidity, nor is it necessarily indicative of sufficient cash flow to fund all of the Company’s needs.

Other real estate companies and the National Association of Real Estate Investment Trusts, or NAREIT, may define this term in a different manner. We have included the NAREIT FFO definition as of May 17, 2016 in the table on page 9 and note that other REITs may not define FFO in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently than we do.

We believe that in order to facilitate a clear understanding of the results of the Company, FFO should be examined in connection with net income or loss and cash flows from operating, investing and financing activities in the consolidated financial statements.

Appendix: Non-GAAP Financial Measure Definitions

Definition of Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA)
and Adjusted EBITDA

EBITDA is defined as net income or loss plus interest expense, income tax expense and depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA excluding hedge ineffectiveness, gains or losses on extinguishment of debt, gains and losses on sales of properties or shares of equity investments or provisions for losses on assets held for sale or equity investments.  EBITDA and Adjusted EBITDA are not intended to represent cash flow for the period, are not presented as an alternative to operating income as an indicator of operating performance, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP and are not indicative of operating income or cash provided by operating activities as determined under GAAP. EBITDA and Adjusted EBITDA are presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company's ability to service or incur debt. Because all companies do not calculate EBITDA or Adjusted EBITDA the same way, this presentation may not be comparable to similarly titled measures of other companies. The Company believes that net income or loss is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to EBITDA and Adjusted EBITDA.

Definition of Property Net Operating Income (Property NOI)

The Company provides property performance based on Net Operating Income, which we refer to as NOI. Management believes that investors are interested in this information. NOI is a non-GAAP financial measure that the Company defines as net income or loss (the most directly comparable GAAP financial measure) plus general and administrative expenses, depreciation and amortization, including amortization of acquired above and below market lease intangibles and impairment charges, interest expense, less equity in earnings of nonconsolidated REITs, interest income, management fee income, hedge ineffectiveness, gains or losses on extinguishment of debt, gains or losses on the sale of assets and excludes non-property specific income and expenses.  The information presented includes footnotes and the data is shown by region with properties owned in the periods presented, which we call Same Store. The comparative Same Store results include properties held for all periods presented.  We also exclude properties that have been acquired, consolidated or placed in service, but that do not have operating activity for all periods presented, dispositions and significant nonrecurring income such as bankruptcy settlements and lease termination fees.  NOI, as defined by the Company, may not be comparable to NOI reported by other REITs that define NOI differently. NOI should not be considered an alternative to net income or loss as an indication of our performance or to cash flows as a measure of the Company's liquidity or its ability to make distributions.

Appendix: Non-GAAP Financial Measure Definitions

Definition of Adjusted Funds From Operations (AFFO)

The Company also evaluates performance based on Adjusted Funds From Operations, which we refer to as AFFO.  The Company defines AFFO as (1) FFO, (2) excluding loss on extinguishment of debt that is non-cash, (3) excluding our proportionate share of FFO and including distributions received, from non-consolidated REITs, (4) excluding the effect of straight-line rent, (5) plus the amortization of deferred financing costs, (6) plus the value of shares issued as compensation and (7) less recurring capital expenditures that are generally for maintenance of properties, which we call non-investment capex or are second generation capital expenditures.  Second generation costs include re-tenanting space after a tenant vacates, which include tenant improvements and leasing commissions.  

We exclude development/redevelopment activities, capital expenditures planned at acquisition and costs to reposition a property. We also exclude first generation leasing costs, which are generally to fill vacant space in properties we acquire or were planned for at acquisition.  

AFFO should not be considered as an alternative to net income or loss (determined in accordance with GAAP), nor as an indicator of the Company’s financial performance, nor as an alternative to cash flows from operating activities (determined in accordance with GAAP), nor as a measure of the Company’s liquidity, nor is it necessarily indicative of sufficient cash flow to fund all of the Company’s needs.  Other real estate companies may define this term in a different manner.  We believe that in order to facilitate a clear understanding of the results of the Company, AFFO should be examined in connection with net income or loss and cash flows from operating, investing and financing activities in the consolidated financial statements.
