EXHIBIT 99.1 NATURAL RESOURCE PARTNERS L.P. REPORTS FIRST QUARTER 2003 RESULTS HOUSTON, May 8, 2003 /PRNewswire-FirstCall via COMTEX/ -- Natural Resource Partners L.P. (NYSE: NRP) today reported net income of $8.0 million or $0.34 per unit for the first quarter ended March 31, 2003, its first full quarter of operations since its initial public offering in October 2002. Earnings before interest, taxes and depletion and amortization (EBITDA) for the same period were $14.2 million. During the first quarter of 2003, NRP's lessees sold 9.8 million tons of coal generating $15.4 million of coal royalty revenues for average royalty revenue per ton of $1.57. The results include two months of coal royalty revenues generated from NRP's acquisition of an overriding royalty interest from Alpha Natural Resources in February. General and administrative costs for the first quarter were higher than originally anticipated. Included in these costs is an allowance for a potential bad debt expense of $305,000 due to a bankruptcy petition filed by one of our lessees. However, NRP does not anticipate any further allowances will be required due to the bankruptcy filing. In addition, the partnership established a policy to accrue for expenses expected to be reimbursed to its general partner for awards granted by the Board of Directors in February under the incentive compensation plans. Corbin J. Robertson Jr., Chairman and Chief Executive Officer of Natural Resource Partners L.P., said, "Our first quarter results came in as expected and we are pleased with our performance to date. In the short time that we have been a publicly traded partnership, we announced an increase in our distributions to unitholders, closed three acquisitions and have grown our reserves by more than 30%. Our strategy is to continue to grow our assets in a way that is accretive to our unitholders." 2003 Outlook For 2003, Natural Resource Partners expects its lessees to produce between 40.5 million tons and 43.0 million tons of coal with approximately 82% to 84% being produced in Appalachia, 4% to 6% in the Illinois Basin and 9% to 11% from the Northern Powder River Basin. This production should generate coal royalty revenues of approximately $65 million to $69.5 million with total revenues of approximately $75 million to $79 million based upon average selling prices provided by its lessees. General and administrative costs are forecasted to range between $6.7 and $6.9 million. NRP expects net income to be between $34 million and $37 million, with depletion and amortization expected to range between $23 million and $25 million. Revenues are anticipated to be higher in the second half of 2003 due to increased production and the full year impact of the acquisitions made thus far in 2003. General and administrative costs will be generally higher in the first half of the year due to the allowance for bad debts, annual audit, annual report and K-1 reporting requirements for its unitholders. The above estimates assume average borrowings of $108 million remain drawn under the current credit facility. Distributions On May 15, 2003, Natural Resource Partners will make a distribution of $12.1 million or $0.5225 per unit on all 22.7 million limited partner units outstanding as well as the 2% distribution with respect to the general partner interest. This distribution represents an increase of $0.01 per unit over the minimum quarterly distribution established at the time of the initial public offering and equates to an annualized distribution of $2.09 per unit. Disclosure of Non-GAAP Financial Measures NRP calculates EBITDA by adding depletion, amortization and interest expense to net income. EBITDA is not presented in accordance with generally accepted accounting principles (GAAP) and is not intended to be used in lieu of GAAP presentations of results of operations or cash provided by operating activities. EBITDA is presented because management believes it provides additional information with respect to both the performance of our fundamental business activities as well as our ability to meet our future debt service, working capital requirements and minimum distributions. Management also believes that debt holders and investment analysts commonly use EBITDA to analyze company performance. A reconciliation of EBITDA to net income is included in the tables attached to this release.
