WILLIS LEASE FINANCE REPORTS FIRST QUARTER PROFIT OF $566,000

SAUSALITO, CA – May 11, 2005—Willis Lease Finance Corporation (NASDAQ: WLFC), a leading lessor of commercial jet engines, today reported net income of $566,000, or $0.06 per diluted share, in the first quarter compared to $969,000, or $0.11 per diluted share, in the first quarter of 2004. Higher revenues only partially offset increased financing costs and depreciation expense in the quarter.

Current Market

“We are seeing some very positive trends in the marketplace,” said Charles F. Willis, President and CEO. “Despite the high cost of fuel and heavy competition, the international aviation market is seeing substantial growth. For example, recent deregulation in India is opening that huge country to expanded commercial aviation services sparking a surge of new activity there. In the last year, four new low cost carriers were started to serve the Indian market, creating demand for new and used aircraft and aviation services across the board. China continues to generate strong growth; and South America and Europe are also seeing solid improvement.”

“Another trend worth noting is the growing demand for leased engines,” continued Willis. “Supply and demand conditions for engine lessors are probably more favorable than they have been at any time since early 2001. Lease rates are continuing to increase and lease terms are getting noticeably longer. In addition, it has been a long time since I saw so many purchase leaseback opportunities available in the marketplace.”

“Despite improving market conditions, our first quarter results were heavily impacted by higher net finance costs,” said Willis. “Since the end of the first quarter last year, 1-month LIBOR more than doubled from 1.09% to 2.87% at the end of March 2005. With a high percentage of our finance costs tied to 1-month LIBOR or commercial paper rates, the rise in rates in the last year has increased our net finance costs by 25% from the same quarter a year ago. We have hedged about 40% of our floating rate debt. Because roughly half of our portfolio consists of leases with remaining terms of 12 months or less, we have an opportunity to increase rents on expiring leases as they come up for renewal or as engines go to new lessees. In the past we have been quite successful in passing along the impact of increased funding costs, albeit at somewhat of a lag behind movements in interest rates. In response to higher interest rates, we started raising lease rates over a year ago. This process is continuing, supported by very healthy demand in the marketplace for our engines.”

Results from Operations

“In the first quarter, our utilization rate improved to 89.2% at March 31, 2005, compared to 85.8% at December 31, 2004, and 88.0% at March 31, 2004, reflecting continued strong demand for our engines,” said Donald A. Nunemaker, Chief Operating Officer. “As of April 30, 2005, we are back over 90% again at 91.1%. Average utilization in the first quarter of 2005 was 87.7% compared to 90.6% in the first quarter a year ago, yet despite lower utilization and only marginal growth in the average size of the lease portfolio, we were still able to increase lease revenue by 2% due to higher lease rates. Included in the utilization rate calculation are the four CFM56-7B engines we purchased new —one in 3Q04, two in 4Q04 and one in 1Q05 — none of which have been leased yet,” Nunemaker said. “If these new engines were eliminated from the utilization rate calculation, utilization would have been 94.2% at March 31, 2005, and 89.3% at year-end. We are developing solid interest in these engines that provide power for the popular Boeing 737-NG aircraft, and we are optimistic they will begin to contribute to revenues and earnings in the near future.”

Lease revenue in the first quarter of 2005 was up 2%, or $271,000, to $15.0 million compared to the first quarter of 2004. Sales of equipment generated a net gain of $732,000 in the first quarter of 2005 and $148,000 in the first quarter a year ago. Other income totaled $101,000 in the first quarter of 2005 compared to $174,000 in the same quarter last year.

First quarter operating expenses increased $1.4 million, or 10%, to $15.1 million from $13.7 million a year ago, primarily due to the $1.1 million increase in net interest and finance costs.

Depreciation, the largest single expense, increased 6% in the first quarter to $6.0 million compared to $5.7 million in the same period last year, reflecting changes in estimates of useful lives and values on older engines types.

First quarter net interest and finance costs increased 25% to $5.4 million from $4.3 million in the first quarter a year ago, due to the substantial increase in short-term interest rates over the past 12 months. “With almost half our portfolio in leases that mature within a year, and with lease rates rising to reflect the higher interest rate environment, pressure on our margin could ease in the remainder of this year,” noted Monica J. Burke, Chief Financial Officer. “In addition, we continue to monitor our exposure to short-term interest rates and manage our hedged position.”

“General & administrative expense declined slightly in the first quarter to $3.6 million compared to $3.7 million in the first quarter a year ago, due to decreased employee costs and engine-related maintenance expenses, offset by higher travel-related costs and outside technical services expenses,” Burke added.
