NEWS RELEASE

WILLIS LEASE FINANCE REPORTS FULL YEAR 2004 PROFIT OF $3.9 MILLION

SAUSALITO, CA – March 22, 2005–Willis Lease Finance Corporation (NASDAQ: WLFC), a leading lessor of commercial jet engines, today reported net income increased to $1.5 million, or $0.16 per diluted share, in the fourth quarter compared to $1.4 million, or $0.16 per diluted share, in the fourth quarter of 2003. For the full year 2004, the company earned $3.9 million, or $0.42 per diluted share, compared to $4.2 million, or $0.47 per diluted share, for 2003.

Current Market

“While I am pleased with how we handled the challenges we faced in 2004, we still have a way to go to reach a more acceptable level of profitability,” said Charles F. Willis, President and CEO. “In 2005, we need to work hard to increase our revenue through higher utilization, growth of the portfolio and fee-based services. Engine leasing continues to be a good alternative for improving industry capital allocation and asset management, fueling demand for our equipment.”

“In 2004, we found several opportunities to expand our portfolio and lay the groundwork for future growth,” Willis continued. “We agreed to buy five brand new jet engines for approximately $35 million. Usually when we buy new equipment, it is in a purchase/leaseback arrangement; however, we were able to negotiate very attractive terms and have already taken delivery of four of these engines. We renewed our revolving credit facility and expanded it by more than $23 million to $148.5 million with a diverse syndicate of global banks, which included five new participant banks. We expanded our engine-sharing program with a second pooling agreement with several Chinese airlines. The two Chinese engine-sharing agreements cover the CFM 56-3C1 and the CFM56-7B engines, two of the most popular engines in the market today. We also expanded our fee based third-party lease placement service, which generated more than $500,000 in incremental revenues in 2004. This program allows us to leverage our relationships in the market, and generate additional revenues without additional investments in assets. These initiatives are critically important to the long-term success of our business.”

Results from Operations

“Strong demand for leased engines from maintenance, repair and overhaul (MRO) shops, plus strong demand from airlines flying older aircraft types like B737 Classics and MD-80’s helped boost average utilization during 2004,” said Donald A. Nunemaker, Chief Operating Officer. “Average utilization in 2004 improved to 89% from 87% in 2003 and 82% in 2002. At December 31, 2004 our utilization rate was 86%, and at February 28, 2005, it had increased to 88%. Included in the utilization rate calculation are the engines we purchased new —one in 3Q04, two in 4Q04 and one in 1Q05 — none of which have yet been leased. If these new engines are eliminated from the utilization rate calculation, we would have ended up at 89% on December 31, 2004 and 93% at February 28, 2005.”

Lease revenue in 2004 was up 2% to $58.2 million compared to $57.0 million in 2003. The comparison this year was affected by $670,000 of security deposits added to lease revenue in the second quarter of 2003 from a customer that went out of business in 2001. Fourth quarter lease revenue increased 5% to $15.1 million compared to $14.4 million in the fourth quarter a year ago. Sales of equipment generated a net gain of $1.9 million in the fourth quarter and $3.1 million in 2004, compared to $1.3 million and $2.4 million in the respective periods of 2003. Other income totaled $141,000 in the fourth quarter and $677,000 in 2004, compared to $272,000 and $520,000 in the respective periods of 2003.

Operating expenses in 2004 increased 5% to $56.6 million from $54.0 million a year ago. In the fourth quarter of 2004, total operating expenses increased 7% to $15.1 million from $14.1 million in the fourth quarter of 2003. Depreciation, the largest single expense, increased 7% in 2004 and 6% in the fourth quarter compared to the same periods last year. “At the end of 2003 and during 2004, we implemented changes in estimates of useful lives and residual values on certain older engine types, which increased the depreciation on those engines,” noted Monica J. Burke, Chief Financial Officer. Write-downs of equipment in 2004 totaled $577,000 compared to $1.3 million in 2003.

General & administrative expense increased 7% in 2004 to $14.8 million compared to $13.9 million a year ago, due to higher legal and accounting, engine-related maintenance and inspection costs, insurance and travel expenses. Reflecting the general rise in interest rates, net finance costs rose 5% in 2004 to $18.0 million compared to $17.2 million in 2003. “Most of our debt is tied to LIBOR, which almost doubled this year, and lease rates do not adjust as quickly as our floating rate debt. Our hedging strategy is providing some protection from upward movement in finance costs,” Burke added.

At December 31, 2004, the company had 115 commercial jet engines, 3 aircraft parts packages, 5 aircraft and other engine-related equipment in its lease portfolio with a net book value of $511.4 million, compared to 119 commercial jet engines, 4 aircraft parts packages, 7 aircraft and other engine-related equipment in its lease portfolio with a net book value of $505.0 million at December 31, 2003.
