Statements contained in this presentation, including statements with respect to future earnings, energy prices, margins and sales,

growth, revenues, expenses, cash flow, acquisitions and dispositions, marketing performance, hedging, financing, exchange rates,
corporate strategy and generating capacity and performance, are “forward-looking statements” within the meaning of the federal
securities laws. Although PPL Corporation believes that the expectations and assumptions reflected in these forward-looking
statements are reasonable, these statements are subject to a number of risks and uncertainties, and actual results may differ materially
from the results discussed in the statements. The following are among the important factors that could cause actual results to differ
materially from the forward-looking statements: market demand and prices for energy, capacity and fuel; weather conditions affecting
customer energy usage and operating costs; competition in power markets; the effect of any business or industry restructuring; the
profitability and liquidity of PPL Corporation and its subsidiaries; new accounting requirements or new interpretations or applications of
existing requirements; operating performance of plants and other facilities; environmental conditions and requirements and the related
costs of compliance, including environmental capital expenditures and emission allowance and other expenses; system conditions and
operating costs; development of new projects, markets and technologies; performance of new ventures; asset acquisitions and
dispositions, including the proposed acquisition of E.ON U.S.; any impact of hurricanes or other severe weather on our business,
including any impact on fuel prices; receipt of necessary government permits, approvals, rate relief and regulatory cost recovery;
capital market conditions and decisions regarding capital structure; the impact of state, federal or foreign investigations applicable to
PPL Corporation and its subsidiaries; the outcome of litigation against PPL Corporation and its subsidiaries; stock price performance;
the market prices of equity securities and the impact on pension income and resultant cash funding requirements for defined benefit
pension plans; the securities and credit ratings of PPL Corporation and its subsidiaries; political, regulatory or economic conditions in
states, regions or countries where PPL Corporation or its subsidiaries conduct business, including any potential effects of threatened or
actual terrorism or war or other hostilities; foreign exchange rates; new state, federal or foreign legislation, including new tax legislation;
and the commitments and liabilities of PPL Corporation and its subsidiaries. Any such forward-looking statements should be
considered in light of such important factors and in conjunction with PPL Corporation’s Form 10-K and other reports on file with the
Securities and Exchange Commission.

Forward-Looking Information Statement

A-24

“Earnings from ongoing operations” should not be considered as an alternative to reported earnings, or net income attributable to PPL, which is
an indicator of operating performance determined in accordance with generally accepted accounting principles (GAAP). PPL believes that
“earnings from ongoing operations,” although a non-GAAP financial measure, is also useful and meaningful to investors because it provides
them with management’s view of PPL’s fundamental earnings performance as another criterion in making their investment decisions. PPL’s
management also uses “earnings from ongoing operations” in measuring certain corporate performance goals. Other companies may use
different measures to present financial performance.

“Earnings from ongoing operations” is adjusted for the impact of special items. Special items include:

• Energy-related economic activity (as discussed below).

• Foreign currency-related economic hedges.

• Sales of assets not in the ordinary course of business.

• Impairment charges (including impairments of securities in the company’s nuclear decommissioning trust funds).

• Workforce reduction and other restructuring impacts.

• Other charges or credits that are, in management’s view, not reflective of the company’s ongoing operations.

Energy-related economic activity includes the changes in fair value of positions used to economically hedge a portion of the economic value of
PPL’s generation assets, load-following and retail activities. This economic value is subject to changes in fair value due to market price volatility
of the input and output commodities (e.g., fuel and power). Also included in this special item is the ineffective portion of qualifying cash flow
hedges and the premium amortization associated with options classified as economic activity. These items are included in ongoing earnings
over the delivery period of the item that was hedged or upon realization. Management believes that adjusting for such amounts provides a
better matching of earnings from ongoing operations to the actual amounts settled for PPL’s underlying hedged assets. Please refer to the
Notes to the Consolidated Financial Statements and MD&A in PPL Corporation’s periodic filings with the Securities and Exchange Commission
for additional information on energy-related economic activity.

“Free cash flow before dividends” is derived by deducting capital expenditures and other investing activities-net, from cash flow from
operations. Free cash flow before dividends should not be considered as an alternative to cash flow from operations, which is determined in
accordance with GAAP. PPL believes that free cash flow before dividends, although a non-GAAP measure, is an important measure to both
management and investors since it is an indicator of the company’s ability to sustain operations and growth without additional outside financing
beyond the requirement to fund maturing debt obligations. Other companies may calculate free cash flow before dividends in a different
manner.

Definitions of Non-GAAP Financial Measures

A-25

"Domestic Gross Energy Margins" and "Domestic Gross Delivery Margins" are not intended to replace "Operating Income," which is
determined in accordance with GAAP, as an indicator of overall operating performance.

•"Domestic Gross Energy Margins" is a single financial performance measure of PPL's domestic energy non-trading and trading
activities. In calculating this measure, the Supply segment's energy revenues are offset by the cost of fuel and energy purchases, and
adjusted for other related items. This performance measure excludes utility revenues and includes revenues from energy sales to PPL
Electric by PPL EnergyPlus. In addition, PPL excludes from "Domestic Gross Energy Margins" energy-related economic activity, which
includes the changes in fair value of positions used to economically hedge a portion of the economic value of PPL's generation assets,
load-following and retail activities. This economic value is subject to changes in fair value due to market price volatility of the input and
output commodities (e.g., fuel and power) prior to the delivery period that was hedged. Also included in this energy-related economic
activity is the ineffective portion of qualifying cash flow hedges and the premium amortization associated with options. This economic
activity is deferred and included in earnings over the delivery period that was hedged. PPL believes that "Domestic Gross Energy
Margins" provides another criterion to make investment decisions. This performance measure is used, in conjunction with other
information, internally by senior management and the Board of Directors to manage its domestic energy non-trading and trading
activities. PPL's management also uses "Domestic Gross Energy Margins" in measuring certain corporate performance goals used in
determining variable compensation. Other companies may use different measures to present the results of their energy non-trading
and trading activities.

•"Domestic Gross Delivery Margins" is a single financial performance measure of PPL's domestic regulated electric delivery operations,
which includes transmission and distribution activities, including PLR energy supply. In calculating this measure, domestic regulated
utility revenues and expenses associated with approved recovery mechanisms, including energy provided as a PLR, are offset. These
mechanisms allow for full cost recovery of certain expenses; therefore certain expenses and revenues offset with minimal impact on
earnings. As a result, this measure represents the net revenues from PPL's domestic regulated electric delivery operations. This
performance measure is used, in conjunction with other information, internally by senior management and the Board of Directors to
