Stamford, CT. February 11, 2015 – Aircastle Limited (the “Company” or “Aircastle”) (NYSE: AYR) reported fourth quarter 2015 net income of $50.6 million, or $0.63 per diluted common share and adjusted net income of $54.3 million, or $0.67 per diluted common share. Net income for the year

Note: Non-GAAP items reconciled in the Appendix.

ended December 31, 2015 was $121.7 million, or $1.50 per diluted common share, and adjusted net income was $142.3 million, or $1.75 per diluted common share. The fourth quarter results included lease rental and finance lease revenues of $185.7 million, an increase of 3%, versus $179.8 million in the fourth quarter of 2014. For the full year 2015, lease rental and finance lease revenues were $741.1 million, up 2% versus $725.6 million in 2014.

Commenting on the results, Ron Wainshal, Aircastle’s CEO, stated, “Aircastle’s results for the fourth quarter of 2015 were excellent and reflect our continuing successes in seizing the opportunities available in the market last year. For the full year, our accomplishments include record gains from asset sales, consistently excellent operating performance and the aggressive moves we completed to address nearly all of our lease placement requirements for 2016 while actively pruning suboptimal exposures and assets. Importantly, we also enhanced our liquidity base and broadened our banking relationships, leveraging our strategic partnership with Marubeni.”

Mr. Wainshal continued, “Throughout the year we retained our discipline as buyers while still managing to complete $1.4 billion in acquisitions, focusing on narrow-body aircraft. We further demonstrated our commitment to deploy capital efficiently by increasing our dividend and pursuing share buy-backs during the recent stock market drop, returning $123 million in capital to shareholders since the beginning of 2015.”

Mr. Wainshal concluded, “As we look at the current macroeconomic and financial market turbulence, it reaffirms our approach of selectively limiting future capital commitments and maintaining investment flexibility, especially given the fluid historical realities of the markets. The steps we’ve taken to de-risk our business combined with our firm and principled commitment to identifying and exploiting optimum value points in time continues to stand us in good stead. I am confident that Aircastle is fundamentally well positioned to grow and prosper going forward.”

Financial Results

Fourth Quarter Results

Total revenues for the fourth quarter were $208.3 million, a decline of $30.0 million, driven by lower maintenance revenues, which typically arise at lease end. Maintenance revenues were $37.1 million lower due to fewer aircraft coming off lease during the fourth quarter of 2015, as compared to 2014 when we early terminated the leases of several aircraft that had been leased to airlines based in Russia and Ukraine.

Adjusted EBITDA for the fourth quarter was $211.0 million, down $22.2 million from the fourth quarter of 2014, due primarily to lower maintenance revenues, partially offset by a $5.9 million increase in lease rental and finance lease revenues and an increase of $5.2 million from gains on sale of flight equipment.

Adjusted net income for the quarter was $54.3 million, down $25.9 million year-over-year. The decrease was due primarily to lower maintenance revenues and a $7.1 million increase in depreciation expense, partially offset by a $9.5 million reduction in non-cash impairment charges arising from the early return and sale of several aircraft during the fourth quarter of 2014.

Full Year Results

Total revenues in 2015 were $819.2 million, essentially flat with the previous year. Lease rental revenues increased $18.8 million versus the previous year, reflecting the growth in flight equipment. However, this increase was largely offset by a $17.0 million reduction in maintenance revenues caused by a lower number of aircraft coming off lease in 2015 compared to the previous year.

Adjusted EBITDA for the full year was $832.1 million, up $39.8 million versus 2014, primarily reflecting $34.9 million more in gains from the sale of flight equipment and a $6.5 million increase in other revenues which included termination fees associated with the disposal of freighter aircraft during 2015.

Adjusted net income for the full year was $142.3 million compared to $167.6 million in 2014, a decrease of $25.4 million. Adjusted net income in 2014 excluded a $36.6 million charge associated with the early repayment of 9.75% debt, which was refinanced at a substantially lower coupon.

Aviation Assets

During 2015, we acquired 46 aircraft for $1.4 billion, including 14 aircraft for $384.8 million during the fourth quarter. The average age of the aircraft acquired during 2015 was 5.0 years and the leases had an average remaining term of approximately 8.6 years. Of the 46 aircraft purchased during the year, 43 were narrow-bodies.

We currently have acquired or committed to acquire ten narrow-body aircraft in 2016 for $380 million. In addition, during 2015 Aircastle entered into an agreement with Embraer to acquire 25 new technology E-Jet E2 aircraft delivering in 2018 through 2021.

During 2015, we sold 31 aircraft for net proceeds of $562.5 million, and realized a record gain on the sale of flight equipment of $58.0 million. The weighted average age of the aircraft sold during 2015 was 15.5 years.

In the fourth quarter of 2015, we completed the sale of eleven aircraft, including two wide-body and two freighter aircraft. Our portfolio activity helped reduce our freighter exposure to eleven aircraft accounting for ten percent of our total fleet net book value, representing a significant reduction in exposure.

During the first quarter, we continued executing our sales program and we expect to sell six narrow-body aircraft to our joint venture with Ontario Teachers’ Pension Plan (“Teachers’”) for gross proceeds of more than $190 million. The aircraft are leased to major customers and the sale will help us manage portfolio concentrations while improving our return on deployed capital. Upon completion, our joint venture with Teachers’ will have nearly $700 million in assets.

2015 Aircraft Sales through December 31

($ in millions)

As of December 31, 2015, Aircastle owned 162 aircraft having a net book value of $6.1 billion and managed five aircraft on behalf of our joint venture with Teachers’.

Share Repurchases

Since November 2015, the Company acquired 2.6 million shares at an average price of $19.19 per share, 955 thousand shares of which were purchased at an average price of $19.81 per share during the fourth quarter of 2015. We acquired an additional 1.65 million shares at an average price of $18.83 per share since the start of 2016. Aircastle’s Board of Directors just reauthorized our $100 million share repurchase program.

2015 Financing Activity

We raised $800 million of new financing during 2015. This included $500 million of Senior Notes due in 2022 and $150 million in long-term secured bank loans obtained from Japanese institutions. We also increased the size of our Revolving Credit Facility from $450 million to $600 million and extended its maturity to May 2019. The capital raised during the year provided us with additional resources to pursue aircraft acquisitions and enhanced our financial flexibility.

Common Dividend

On February 9, 2016, Aircastle’s Board of Directors declared a first quarter 2016 cash dividend on its common shares of $0.24 per share, payable on March 15, 2016 to shareholders of record on February 29, 2016. Aircastle increased the dividend six times since 2010.

EBITDA and Adjusted EBITDA Reconciliation

(Dollars in thousands)

(Unaudited)

We define EBITDA as income (loss) from continuing operations before income taxes, interest expense, and depreciation and amortization. We use EBITDA to assess our consolidated financial and operating performance, and we believe this non-US GAAP measure is helpful in identifying trends in our performance.

This measure provides an assessment of controllable expenses and affords management the ability to make decisions which are expected to facilitate meeting current financial goals as well as achieving optimal financial performance. It provides an indicator for management to determine if adjustments to current spending decisions are needed.

EBITDA provides us with a measure of operating performance because it assists us in comparing our operating performance on a consistent basis as it removes the impact of our capital structure (primarily interest charges on our outstanding debt) and asset base (primarily depreciation and amortization) from our operating results. Accordingly, this metric measures our financial performance based on operational factors that management can impact in the short-term, namely the cost structure, or expenses, of the organization. EBITDA is one of the metrics used by senior management and the board of directors to review the consolidated financial performance of our business.

We define Adjusted EBITDA as EBITDA (as defined above) further adjusted to give effect to adjustments required in calculating covenant ratios and compliance as that term is defined in the indenture governing our senior unsecured notes. Adjusted EBITDA is a material component of these covenants.

Note: LTM Average Shareholders’ Equity is the average of the most recent five quarters period end Shareholders’ Equity. Management believes that the cash return on equity metric (Cash ROE) when viewed in conjunction with the Company’s results under US GAAP and the above reconciliation, provide useful information about operating and period-over-period performance, and provide additional information that is useful for evaluating the underlying operating performance of our business without regard to periodic reporting impacts related to non-cash revenue and expense items and interest rate derivative accounting, while recognizing the depreciating nature of our assets.
