Capstone Infrastructure Corporation Provides Updated Outlook for 2012 and Future Dividend Policy

Toronto, Ontario (December 6, 2011) – Capstone Infrastructure Corporation (TSX: CSE; CSE.PR.A; CSE.DB.A – “CSE” or the “Corporation”) today updated its outlook for 2012 for Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”) and payout ratio, which is based on Adjusted Funds From Operations (“AFFO”), to reflect the impact of certain external events and internal initiatives subsequent to the Corporation’s previous outlook.

"Our mission is to build a portfolio that delivers a superior total return to our shareholders in the form of income as well as capital appreciation,” said Michael Bernstein, President and Chief Executive Officer. “We are particularly pleased with our recent investment in Bristol Water, a business that is expected to grow rapidly over the next 10 to 15 years, thereby building significant long-term value for our shareholders. Our priorities in 2012 include completing a new contract for Cardinal and strengthening our balance sheet to address near-term financing requirements and to position the Corporation for future growth initiatives. However, while our businesses are performing well operationally, we are facing some near-term challenges and the longer term impact of expected lower returns from Cardinal, both of which will require us to re-evaluate our dividend policy in 2012. We recognize the importance of our dividends to shareholders and will strive to ensure a dividend level that delivers attractive income to shareholders while allowing us to prudently manage our business.”

Outlook for 2012
The Corporation currently expects 2012 Adjusted EBITDA to be approximately $120 million compared with previous estimates of approximately $140 million. The 2012 payout ratio is expected to be approximately 120% to 130% compared with the previously provided outlook of approximately 85% to 90%(1). This updated outlook reflects the following current assumptions:

• TransCanada Pipelines Limited (“TCPL”) recently filed an application to set the 2012 interim gas transportation toll at $2.24 per gigajoule, representing an additional cost to the Cardinal gas cogeneration facility (“Cardinal”) of approximately $7 million in 2012 from previous assumptions. This interim rate is subject to approval by the National Energy Board (“NEB”);
• The Corporation recently finalized the accounting treatment for Bristol Water’s business under International Financial Reporting Standards (“IFRS”), particularly with respect to accounting for maintenance capital expenditures. Additionally, capital expenditures at Bristol Water in 2012 will be higher than in 2011. Combined, these two factors result in an impact of approximately $8 million;
• The Corporation expects Adjusted EBITDA from Cardinal, Erie Shores Wind Farm, the hydro power facilities and Whitecourt combined to be approximately $2 million lower than previously anticipated due to higher costs and lower gas mitigation revenues at Cardinal;
• The recapitalization of Värmevärden, a process that has now been initiated and is currently anticipated to occur in the first quarter of 2012, will reduce the amount of interest income the Corporation receives annually to approximately $4 million from approximately $7 million as previously expected for 2012, reflecting the lower amount of the Corporation’s capital invested in the business. The recapitalization of
Värmevärden is expected to result in approximately $50 to $60 million of net proceeds for the Corporation, thereby strengthening the Corporation’s balance sheet; and
• The Corporation has updated various financing assumptions, including earlier re-financings that potentially include amortization profiles, resulting in higher anticipated financing costs in 2012.

Additionally, the Corporation expects to reinvest a significant portion of Bristol Water’s cash flow into the company’s capital program to support long-term rate base growth and value accretion for shareholders. This will result in limited dividends from Bristol Water to the Corporation over the current regulatory period.

The Corporation is now experiencing lower revenue growth at Cardinal in 2012 and 2013 following implementation of Government of Ontario amendments to the application of the Global Adjustment Mechanism (“GAM”). The GAM previously represented a significant portion of the Ontario Electricity Financial Corporation’s (“OEFC”) Direct Customer Rate (“DCR”), which is the revenue escalator contained in Cardinal’s current Power Purchase Agreement (“PPA”).

Dividend Policy
Based on the Corporation’s existing portfolio, outlook and current dividend level, management expects the payout ratio in 2013 and 2014 to return to the 100% or below range. Notwithstanding this view, at the current dividend level the Corporation’s 2012 payout ratio is now expected to be higher than previously anticipated. Based on the assumptions underlying the 2012 outlook, as identified above and which are subject to change, it is unlikely that the Corporation will continue to pay the current dividend through 2014 as previously expected. The Corporation expects to gain clarity on Cardinal’s future cash flow profile in the first half of 2012. As a result, the Board of Directors and management intend to re-evaluate the Corporation’s dividend policy in 2012.

Outlook for 2011
The Corporation also updated its outlook for 2011 to reflect the impact of IFRS adjustments related to the accounting for Bristol Water. Excluding the one-time costs related to the internalization of management in April 2011, Adjusted EBITDA is expected to be approximately $70 to $75 million, which is generally consistent with the previously provided outlook of approximately $75 million. The payout ratio in 2011, which is based on AFFO and excludes internalization costs, is expected to be approximately 130% compared with approximately 120% previously. The 2011 outlook remains subject to the final purchase price accounting treatment and final transaction costs (such as stamping fees) for Bristol Water, which will be finalized in early 2012.

Investor Day Event
The Corporation will hold its 2011 Investor Day today in Toronto commencing at 4 p.m. ET to discuss this outlook as well as its strategic objectives for 2012. The Investor Day webcast will be available with accompanying slides on the Corporation’s website in the Investor Centre section, which is located at: http://www.capstoneinfrastructure.com/InvestorCentre/EventsandPresentations.aspx

Non-GAAP Measures
This news release contains figures that are performance measures not defined by International Financial Reporting Standards. These non-GAAP performance measures do not have any standardized meaning prescribed by IFRS and are, therefore, unlikely to be comparable to similar measures presented by other issuers. The Corporation believes that these indicators are important since they provide additional information about the Corporation’s performance and cash generating capabilities and facilitate comparison of results over different periods. The Corporation uses Adjusted EBITDA to measure the performance of its assets prior to the impact of financing costs, taxes and charges for depreciation and amortization. Adjusted EBITDA is calculated as revenue less operating expenses and administrative expenses plus interest and dividends/distributions received from equity accounted investments. Adjusted EBITDA is reconciled to net income (loss) by adjusting standardized EBITDA for unrealized gains and losses on derivatives, unrealized loss on Class B exchangeable units, unrealized loss on the conversion option for the convertible debentures maturing on December 31, 2016, foreign exchange gains and losses, equity accounted income and dividends/distributions from equity accounted investments.

The Corporation uses Adjusted Funds From Operations as a measure of cash generated during the period for distribution to shareholders. The Corporation defines AFFO as FFO less maintenance capital expenditures and scheduled repayment of principal on debt, net of changes to the levelization liability. Payout ratio measures the proportion of cash generated from operations that is paid as dividends. The payout ratio is calculated as dividends declared divided by AFFO.

(1) The Corporation’s prior outlook was subject to the final accounting treatment for Bristol Water transaction costs and Bristol Water’s business under International Financial Reporting Standards, the actual results of the business, and foreign currency rates for financial reporting purposes. Other assumptions underlying the previous 2012 outlook included a full year of contribution from the Amherstburg Solar Park, Värmevärden and Bristol Water; and that the TransCanada Pipelines Limited gas transportation rate in 2012 would return to the 2010 rate of $1.64 per gigajoule from the 2011 rate of $2.24 per gigajoule.
