- ----------
(a)  The net effect on net electric operating revenues from realization of
     prior-period mark-to-market included in line 39 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not revenue
     recognition. The arithmetic opposites of amounts included in line 35 are
     included in lines 31 and 34. For example, line 35 shows that a prior-period
     mark-to-market gain of $3 million was transferred to "realized" for the
     first quarter of 2003. Lines 31 and 34 include amounts totaling $3 million
     of realized revenues for the first quarter of 2003.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of March 31, 2003, Pinnacle West had accumulated mark-to-market net gains of
$35 million related to our power marketing and trading activities. We estimate
that these gains will be reclassified to realized gains as the underlying
commodities are delivered, as follows: remainder of 2003, $2 million; 2004, $10
million; 2005, $10 million; 2006 and thereafter, $13 million.

- ----------
(a)  The net effect on pretax gross margin from realization of prior-period
     mark-to-market included in line 60 and in line 64 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not earnings
     recognition. The arithmetic opposites of amounts included in line 56 are
     included in line 52. The opposites of amounts included in line 57 are
     included in line 54. For example, line 56 shows that a prior-period
     mark-to-market gain of $5 million was transferred to "realized" for the
     first quarter of 2003. A $5 million realized gain is included in the $24
     million on line 52 for the first quarter of 2003.

(b)  Quarterly amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

- ----------
(a)  The net effect on net electric operating revenues from realization of
     prior-period mark-to-market included in line 39 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not revenue
     recognition. The arithmetic opposites of amounts included in line 35 are
     included in lines 31 and 34. For example, line 35 shows that a prior-period
     mark-to-market gain of $3 million was transferred to "realized" for the
     first quarter of 2003. Lines 31 and 34 include amounts totaling $3 million
     of realized revenues for the first quarter of 2003.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of March 31, 2003, Pinnacle West had accumulated mark-to-market net gains of
$35 million related to our power marketing and trading activities. We estimate
that these gains will be reclassified to realized gains as the underlying
commodities are delivered, as follows: remainder of 2003, $2 million; 2004, $10
million; 2005, $10 million; 2006 and thereafter, $13 million.

- ----------
(a)  The net effect on pretax gross margin from realization of prior-period
     mark-to-market included in line 60 and in line 64 is zero. Realization of
     prior-period mark-to-market relates to cash flow recognition, not earnings
     recognition. The arithmetic opposites of amounts included in line 56 are
     included in line 52. The opposites of amounts included in line 57 are
     included in line 54. For example, line 56 shows that a prior-period
     mark-to-market gain of $5 million was transferred to "realized" for the
     first quarter of 2003. A $5 million realized gain is included in the $24
     million on line 52 for the first quarter of 2003.

(b)  Quarterly amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 38 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 33 are
     included in lines 28 and 32. For example, line 33 shows that a prior-period
     mark-to-market  gain of $8 million was  transferred  to "realized"  for the
     fourth quarter of 2002. Lines 28 and 32 include amounts totaling $9 million
     of realized revenues for the fourth quarter of 2002.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of December 31, 2002, Pinnacle West had accumulated  mark-to-market net gains
of $41  million  related  to our power  marketing  and  trading  activities.  We
estimate  that  these  gains  will be  reclassified  to  realized  gains  as the
underlying  commodities are delivered,  as follows:  2003, $4 million; 2004, $10
million; 2005 and thereafter, $27 million.

- ----------
(a)  The net effect on pretax  gross  margin from  realization  of  prior-period
     mark-to-market  included in line 59 and in line 64 is zero.  Realization of
     prior-period mark-to-market relates to cash flow recognition,  not earnings
     recognition.  The arithmetic  opposites of amounts  included in line 55 are
     included  in line 51.  The  opposites  of amounts  included  in line 56 are
     included  in line  53.  For  example,  line 55  shows  that a  prior-period
     mark-to-market  gain of $4 million was  transferred  to "realized"  for the
     fourth  quarter of 2002. A $4 million  realized gain is included in the $23
     million on line 51 for the fourth quarter of 2002.
(b)  Quarterly  amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 38 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 33 are
     included in lines 29 and 32. For example, line 33 shows that a prior-period
     mark-to-market  gain of $1 million was  transferred  to "realized"  for the
     total year 2001.  Lines 29 and 32 include  amounts  totaling  $1 million of
     realized revenues for the year 2001.

FUTURE MARKETING AND TRADING MARK-TO-MARKET REALIZATION

As of December 31, 2001, Pinnacle West had accumulated  mark-to-market net gains
of $138.0  million  related to our power  marketing and trading  activities.  We
estimate  that  these  gains  will be  reclassified  to  realized  gains  as the
underlying  commodities are delivered,  as follows:  2002, $43.0 million;  2003,
$22.6 million; 2004, $23.6 million; 2005 and thereafter, $48.8 million.

- ----------
(a)  The net effect on pretax  gross  margin from  realization  of  prior-period
     mark-to-market  included in line 59 and in line 63 is zero.  Realization of
     prior-period mark-to-market relates to cash flow recognition,  not earnings
     recognition.  The arithmetic  opposites of amounts  included in line 55 are
     included  in line 51.  The  opposites  of amounts  included  in line 56 are
     included  in line  53.  For  example,  line 55  shows  that a  prior-period
     mark-to-market  gain of $11 million was  transferred  to "realized" for the
     total  year 2001.  A $11  million  realized  gain is  included  in the $117
     million on line 51 for the total year 2001.
(b)  Quarterly  amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 38 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 33 are
     included in lines 29 and 32. For example, line 33 shows that a prior-period
     mark-to-market  gain of $2 million was  transferred  to "realized"  for the
     total year 2000.  Lines 29 and 32 include  amounts  totaling  $2 million of
     realized revenues for the year 2000.

- ----------
(a)  The net effect on pretax  gross  margin from  realization  of  prior-period
     mark-to-market  included in line 59 and in line 63 is zero.  Realization of
     prior-period mark-to-market relates to cash flow recognition,  not earnings
     recognition.  The arithmetic  opposites of amounts  included in line 55 are
     included  in line 51.  The  opposites  of amounts  included  in line 56 are
     included  in line  53.  For  example,  line 55  shows  that a  prior-period
     mark-to-market  gain of $2 million was  transferred  to "realized"  for the
     total year 2000. A $2 million  realized gain is included in the $69 million
     on line 51 for the total year 2000.
(b)  Quarterly  amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.

- ----------
(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 38 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 33 are
     included in lines 29 and 32. For example, line 33 shows that a prior-period
     mark-to-market  gain of $0 million was  transferred  to "realized"  for the
     total year 1999.  Lines 29 and 32 include  amounts  totaling  $0 million of
     realized revenues for the year 1999.

                    FOR PERIODS ENDED MARCH 31, 2003 AND 2002

     This discussion explains the changes in our consolidated earnings for the
three month and twelve month periods ended March 31, 2003 and 2002. Condensed
Consolidated Statements of Income for the three and twelve months ended March
31, 2003 and 2002 follow this discussion. We will file our Quarterly Report on
Form 10-Q for the quarter ended March 31, 2003 on or before May 15, 2003. We
suggest this section be read in connection with the Pinnacle West Capital
Corporation Annual Report on Form 10-K for the fiscal year ended December 31,
2002. We have reclassified certain prior period amounts to conform to our
current period presentation. Additional operating and financial statistics and a
glossary of terms are available on our website (www.pinnaclewest.com).

EARNINGS CONTRIBUTIONS BY SUBSIDIARY AND BUSINESS SEGMENT

     We have three principal business segments (determined by products, services
and the regulatory environment):

     *    our regulated electricity segment, which consists of regulated
          traditional retail and wholesale electricity businesses and related
          activities and includes electricity generation, transmission and
          distribution;

     *    our marketing and trading segment, which consists of our competitive
          energy business activities, including wholesale marketing and trading
          and APS Energy Services' commodity-related energy services; and

     *    our real estate segment, which consists of SunCor's real estate
          development and investment activities.

     The following tables summarize net income and segment details for the three
and twelve months ended March 31, 2003 and the comparable prior periods for
Pinnacle West and each of our subsidiaries (dollars in millions):

(a)  See "Real Estate Activities" discussion below.

(b)  Consistent with APS' October 2001 ACC filing, APS entered into agreements
     with its affiliates to buy power through June 2003. The agreements reflect
     a price based on the fully-dispatchable dedication of the Pinnacle West
     Energy generating assets to APS' Native Load customers. Under the ACC
     "Track B" order, APS is required to solicited bids for certain estimated
     capacity and energy requirements for periods beginning July 1, 2003.
     Pinnacle West Energy is eligible to bid to supply APS' electricity
     requirements.

(c)  APS Energy Services' net income prior to 2003 and El Dorado's net income
     are primarily reported before income taxes. The income tax expense or
     benefit for these subsidiaries was recorded at the parent company.

(d)  Primarily includes activities related to El Dorado in the twelve months
     ended March 31, 2003, principally El Dorado's investment in NAC
     International, Inc. (NAC). For the twelve months ended March 31, 2003, we
     recorded a pretax loss of $55 million related to NAC contracts with two
     customers.

(e)  In the fourth quarter of 2002, Pinnacle West Energy recorded a charge
     related to the cancellation of Redhawk Units 3 and 4 of approximately $30
     million after income taxes ($49 million pretax).

(f)  We recorded a $66 million after tax charge as of October 1, 2002 for the
     cumulative effect of a change in accounting for trading activities, for the
     early adoption of EITF 02-3, "Issues Involved in Accounting for Derivative
     Contracts Held for Trading Purposes and Contracts Involved in Energy
     Trading and Risk Management Activities."

(g)  APS recorded a $12 million after tax charge in June 2001 for the cumulative
     effect of a change in accounting for derivatives related to the adoption of
     SFAS No. 133, "Accounting for Derivative Instruments and Hedging
     Activities."

RESULTS OF OPERATIONS

     GENERAL

     Throughout the following explanations of our results of operations, we
refer to "gross margin." With respect to our regulated electricity segment and
our marketing and trading segment, gross margin refers to electric operating
revenues less purchased power and fuel costs. Our real estate segment gross
margin refers to real estate revenues less real estate operations costs of
SunCor. Other gross margin refers to other operating revenues less other
operating expenses, which includes El Dorado's investment in NAC, which we began
consolidating in our financial statements in July 2002. Other gross margin also
includes amounts related to APS Energy Services' energy consulting services.

     OPERATING RESULTS - THREE MONTH PERIOD ENDED MARCH 31, 2003 COMPARED WITH
     THREE-MONTH PERIOD ENDED MARCH 31, 2002

     Our consolidated net income for the three months ended March 31, 2003 was
$25 million compared with $54 million for the prior year. Included in 2003
income is $5 million of after tax income related primarily to SunCor's sale of

                                        2
<PAGE>
its water utility company accounted for as discontinued operations in our real
estate segment (see "Real Estate Activities" below).

     Our income from continuing operations for the three months ended March 31,
2003 was $20 million compared with $53 million for the comparable period in the
prior year. The period-to-period decrease of $33 million was primarily due to:

     *    lower earnings contributions from our marketing and trading
          activities, reflecting lower liquidity and higher price volatility in
          the wholesale power markets in the western United States, partially
          offset by lower mark-to-market reversals due to the adoption of EITF
          02-3 ($17 million, after tax);

     *    higher depreciation, operations and maintenance, and interest expenses
          related to new power plants in service ($10 million, after tax);

     *    higher operating costs primarily related to the timing of power plant
          overhauls and higher pension and other postretirement benefit costs
          ($7 million, after tax);

     *    decreased earnings contributions from our regulated electricity
          activities, reflecting retail electricity price decreases, the effects
          of milder weather and higher replacement power cost for plant outages,
          partially offset by retail customer growth, ($5 million after tax);
          and

     *    other miscellaneous factors ($2 million, after tax).

     The  above decreases were partially offset by:

     *    higher competitive retail sales in California by APS Energy Services
          ($5 million, after tax); and

     *    the settlement of an NAC contract dispute involving Maine Yankee
          Atomic Power Company ($3 million, after tax).

REGULATED ELECTRICITY SEGMENT GROSS MARGIN

     Regulated electricity segment revenues related to our regulated retail and
wholesale electricity businesses were $5 million higher in the three months
ended March 31, 2003, compared with the same period in the prior year as a
result of:

                                       4
<PAGE>
     *    increased revenues related to traditional wholesale sales as a result
          of higher sales volumes and higher prices ($1 million);
     *    increased revenues related to retail load hedge management wholesale
          sales, primarily as a result of higher prices ($3 million);
     *    decreased retail revenues related to milder weather ($11 million);
     *    increased retail revenues related to customer growth, excluding
          weather effects ($14 million);
     *    decreased retail revenues related to a reduction in retail electricity
          prices ($5 million); and
     *    other miscellaneous factors ($3 million, net increase).

     Regulated electricity segment purchased power and fuel costs were $13
million higher in the three months ended March 31, 2003, compared with the same
period in the prior year as a result of:

     *    increased costs related to traditional wholesale sales as a result of
          higher sales volumes and higher prices ($1 million);
     *    increased costs related to retail load hedge management wholesale
          sales, primarily as a result of higher prices ($3 million);
     *    decreased costs related to the effects of milder weather on retail
          sales ($5 million);
     *    increased costs related to retail sales growth, excluding weather
          effects ($7 million);
     *    increased replacement power costs for power plant outages due to
          higher market prices and more unplanned outages ($4 million); and
     *    other miscellaneous factors ($3 million, net increase).

MARKETING AND TRADING SEGMENT GROSS MARGIN

     Marketing and trading segment revenues were $87 million higher in the three
months ended March 31, 2003, compared with the same period in the prior year as
a result of:

     *    increased revenues from generation sales other than Native Load
          primarily due to higher prices and higher sales volumes ($36 million);
     *    higher realized wholesale revenues net of related mark-to-market
          reversals primarily due to higher volumes ($41 million);
     *    increased revenues from higher competitive retail sales in California
          by APS Energy Services ($30 million);
     *    higher revenues related to the adoption of EITF 02-3 ($8 million); and
     *    lower mark-to-market gains for future delivery primarily as a result
          of lower market liquidity and higher price volatility ($28 million).

     Marketing and trading segment purchased power and fuel costs were $108
million higher in the three months ended March 31, 2003, compared to the same
period in the prior year as a result of:

     *    increased fuel costs related to generation sales other than Native
          Load primarily because of higher natural gas prices and higher sales
          volumes ($35 million);
     *    increased purchased power costs related to other realized marketing
          activities in the current period primarily due to higher volumes and
          higher prices ($53 million);
     *    increased purchased power costs related to higher competitive retail
          sales in California by APS Energy Services ($22 million); and

OTHER INCOME STATEMENT ITEMS

     The decrease in real estate segment gross margin of $2 million was
primarily due to lower land sales. In addition, as discussed in "Real Estate
Activities" below, SunCor had an $8 million ($5 million after tax) gain on the
sale of its water utility company which was reported as income from discontinued
operations in the three months ended March 31, 2003.

     The increase in other gross margin of $5 million was primarily due to NAC's
settlement of a contract dispute involving Maine Yankee Atomic Power Company.

     The increase in operations and maintenance expense of $16 million was due
to increased operating costs related to the timing of power plant overhauls,
increased pension and other postretirement benefit costs, new power plants in
service and other costs.

     The increase in depreciation and amortization expense of $6 million
primarily related to increased plant balances and new power plants, partially
offset by lower regulatory asset amortization.

     Net interest expense increased $7 million primarily because of higher debt
balances related to our generation construction program and lower capitalized
interest on our generation construction program due to completion of Redhawk
Units 1 and 2 in mid-2002.

     OPERATING RESULTS - TWELVE MONTH PERIOD ENDED MARCH 31, 2003 COMPARED WITH
     TWELVE-MONTH PERIOD ENDED MARCH 31, 2002

     Our consolidated net income for the twelve months ended March 31, 2003 was
$121 million compared with $306 million for the prior year. Included in the 2003
period was a $66 million after tax charge for the cumulative effect of a change
in accounting for trading activities for the early adoption of EITF 02-3 on
October 1, 2002 and $14 million of after tax income related to certain
discontinued operations in our real estate segment (see "Real Estate Activities"
below). Included in the 2002 period was a $12 million after tax charge for the
cumulative effect of a change in accounting for derivatives, as required by SFAS
No. 133.

     Our income from continuing operations for the twelve months ended March 31,
2003 was $173 million compared with $317 million for the prior year. The
period-to-period decrease of $144 million was primarily due to:

     *    lower earnings contributions from our marketing and trading
          activities, reflecting lower liquidity and lower price volatility in
          the wholesale power markets in the western United States, partially
          offset by lower mark-to-market reversals due to the adoption of EITF
          02-3 ($104 million, after tax);

     *    losses related to our investment in NAC ($32 million, after tax);

     *    higher operations and maintenance expenses related to the Redhawk
          Units 3 and 4 cancellation charge and 2002 severance costs, partially
          offset by lower generation reliability costs ($32 million, after tax);

     *    higher depreciation, operations and maintenance, and interest expenses
          related to new power plants in service ($27 million, after tax);

     *    higher pension and other postretirement benefit costs ($7 million,
          after tax); and

                                       6
<PAGE>
     *    miscellaneous factors, net ($4 million, after tax).

     The above decreases were partially offset by:

     *    increased earnings contributions from our regulated electricity
          activities, reflecting lower replacement power costs for power plant
          outages, retail customer growth and higher average usage per customer,
          partially offset by the effects of milder weather and retail
          electricity price decreases ($41 million, after tax); and

     *    higher competitive retail sales in California by APS Energy Services
          ($21 million, after tax).

     *    other miscellaneous factors ($1 million net decrease).

     Regulated electricity segment purchased power and fuel costs were $580
million lower in the twelve months ended March 31, 2003, compared with the same
period in the prior year as a result of:

     *    decreased costs related to traditional wholesale sales as a result of
          lower prices and lower sales volumes ($39 million);
     *    decreased costs related to retail load hedge management wholesale
          sales, primarily as a result of lower prices and lower sales volumes
          ($445 million);
     *    charges in 2001 related to purchased power contracts with Enron and
          its affiliates ($13 million net decrease);
     *    decrease in mark-to-market for hedged natural gas and purchased power
          costs for future delivery ($15 million);
     *    decreased costs related to the effects of milder weather on retail
          sales ($23 million);
     *    increased costs related to retail sales growth, excluding weather
          effects ($24 million);
     *    decreased replacement power costs for power plant outages due to lower
          market prices and fewer unplanned outages ($74 million); and
     *    miscellaneous factors ($5 million net increase).

MARKETING AND TRADING SEGMENT GROSS MARGIN

     Marketing and trading segment revenues were $56 million lower in the twelve
months ended March 31, 2003, compared with the same period in the prior year as
a result of:

     *    increased revenues from generation sales other than Native Load
          primarily due to higher sales volumes, partially offset by lower
          market prices ($17 million);
     *    lower realized wholesale revenues net of related mark-to-market
          reversals primarily due to lower prices partially offset by higher
          volumes ($112 million);
     *    increased revenues from higher competitive retail sales in California
          by APS Energy Services ($124 million);
     *    higher revenues related to the adoption of EITF 02-3 ($16 million);
          and
     *    lower mark-to-market gains for future delivery primarily as a result
          of lower market liquidity and lower price volatility ($101 million).

     Marketing and trading segment purchased power and fuel costs were $83
million higher in the twelve months ended March 31, 2003, compared to the same
period in the prior year as a result of:

     *    increased fuel costs related to generation sales other than Native
          Load primarily because of higher sales volumes ($36 million);
     *    decreased purchased power costs related to other realized marketing
          activities in the current period primarily due to lower prices
          partially offset by higher volumes ($44 million);
     *    increased purchased power costs related to higher competitive retail
          sales in California by APS Energy Services ($89 million); and
     *    change in mark-to-market fuel costs for future delivery ($2 million
          increase).

OTHER INCOME STATEMENT ITEMS

     The decrease in real estate segment gross margin of $4 million was
primarily due to lower commercial and property management sales partially offset
by higher home and land sales activities. In addition, as discussed in "Real
Estate Activities" below, SunCor had a $23 million ($14 million after tax) gain
on the sale of its water utility company and a retail center which was reported
as income from discontinued operations in the twelve months ended March 31,
2003.

     The decrease in other gross margin of $40 million was primarily due to
losses on El Dorado's investment in NAC. Losses for the twelve month period
ended March 31, 2003 totaled approximately $55 million on a pretax basis and
were primarily related to NAC contracts with two customers ($47 million was
recorded in other gross margin and $8 million was recorded in other expense). We
reversed $5 million of loss reserves in the first quarter of 2003 related to
NAC's contract settlement. We believe we have reserved our exposure with respect
to these contracts in all material respects and, as a result, we consider these
charges to be non-recurring.

     The increase in operations and maintenance expense of $78 million was due
to a $47 million write-off related to the cancellation of Redhawk Units 3 and 4,
severance costs of $36 million related to a 2002 voluntary workforce reduction,
increased pension and other postretirement benefit costs of $12 million and
other costs of $13 million, partially offset by lower costs related to
generation reliability, plant outages and maintenance costs of $30 million.

     The increase in depreciation and amortization expense of $7 million
primarily related to increased plant balances and new power plants, partially
offset by lower regulatory amortization.

     The increase in taxes other than income taxes of $7 million is primarily
due to increased property taxes on higher property balances.

     Other income decreased $11 million primarily due to an insurance recovery
recorded in 2001 related to environmental remediation costs and other costs.

     Net interest expense increased $25 million primarily because of higher debt
balances related to our generation construction program and lower capitalized
interest on our generation construction program due to completion of Redhawk
Units 1 and 2 in mid-2002.

REAL ESTATE ACTIVITIES

     As discussed in our 2002 10-K, we have undertaken an aggressive effort to
accelerate asset sales activities to approximately double SunCor's annual
earnings in 2003 to 2005 compared with the $19 million in earnings recorded in
2002.

     Certain components of SunCor's real estate sales activities, which are
included in the real estate segment, may be required to be reported as
discontinued operations on our Consolidated Statements of Income in accordance
with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived
Assets." Among other things, SFAS No. 144 prescribes accounting for discontinued
operations and defines certain real estate activities as discontinued
operations. We adopted SFAS No. 144 effective January 1, 2002 and determined
that activities that would have required discontinued operations reporting in
2002, 2001 and 2000 were immaterial. We currently estimate that 20% to 40% of
SunCor's net income in 2003 will be reported in discontinued operations;
however, this ultimately depends on the specific properties sold.

     In the first quarter of 2003, SunCor sold its water utility company, which
resulted in an after tax gain of $5 million ($8 million pretax). The gain on the
sale and operating income in the current and prior periods are classified as
discontinued operations on our Condensed Consolidated Statements of Income.

     In the second quarter of 2002, SunCor sold a retail center, but maintained
a significant continuing involvement through a management contract. In the first
quarter of 2003, this management contract was canceled. As a result, the gain on
the 2002 sale and the operating income related to this property have been
reclassified as discontinued operations. The income from discontinued operations
of $14 million (after income taxes) in the twelve months ended March 31, 2003
primarily reflects this sale and the sale of the water utility company.

     The following chart provides a summary of SunCor's earnings (after income
taxes) for the three and twelve months ended March 31, 2003 and the comparable
prior periods (dollars in millions):

FORWARD-LOOKING STATEMENTS

     This document contains forward-looking statements based on current
expectations and we assume no obligation to update these statements or make any
further statements on any of these issues, except as required by applicable law.
Because actual results may differ materially from expectations, we caution
readers not to place undue reliance on these statements. A number of factors
could cause future results to differ materially from historical results, or from
results or outcomes currently expected or sought by us. These factors include
the ongoing restructuring of the electric industry, including the introduction
of retail electric competition in Arizona and decisions impacting wholesale
competition; the outcome of regulatory and legislative proceedings relating to
the restructuring; state and federal regulatory and legislative decisions and
actions, including price caps and other market constraints imposed by the FERC;
regional economic and market conditions, including the California energy

situation and completion of generation and transmission construction in the
region, which could affect customer growth and the cost of power supplies; the
cost of debt and equity capital and access to capital markets; weather
variations affecting local and regional customer energy usage; the effect of
conservation programs on energy usage; power plant performance; the successful
completion of our generation construction program; regulatory issues associated
with generation construction, such as permitting and licensing; our ability to
compete successfully outside traditional regulated markets (including the
wholesale market); our ability to manage our marketing and trading activities
and the use of derivative contracts in our business; technological developments
in the electric industry; the performance of the stock market, which affects the
amount of our required contributions to our pension plan and nuclear
decommissioning trust funds; the strength of the real estate market in SunCor's
market areas, which include Arizona, New Mexico and Utah; and other
uncertainties, all of which are difficult to predict and many of which are
beyond our control.

                                        because in accordance with
                                        mark-to-market accounting, the margin
                                        was already recorded in the prior
                                        period. A negative amount shown in this
                                        category represents the arithmetic
                                        opposite of a gain recognized in the
                                        period in which the commodities were
                                        delivered; an equal positive amount is
                                        reflected in the realized revenue or
                                        margin for delivered commodities. A
                                        positive amount shown in this category
                                        represents the arithmetic opposite of a
                                        loss recognized in the period in which
                                        the commodities were delivered; an equal
                                        negative amount is reflected in the
                                        realized revenue or margin for delivered

                PINNACLE WEST REPORTS 2003 FIRST QUARTER EARNINGS
                               ON TARGET WITH PLAN

PHOENIX - Pinnacle West Capital Corporation (NYSE: PNW) today reported
consolidated net income for the quarter ended March 31, 2003, of $25.3 million,
or $0.28 per diluted share of common stock. This result compares with $53.8
million, or $0.63 per share, for the comparable quarter a year ago.

"Quarterly results were on target with our plan, and our outlook for the year
remains unchanged. However, we continue to monitor the uncertainties in the
western wholesale power markets and their potential impact on our results," said
Chairman Bill Post, adding that the Company's operations and market base remain
strong.

"The growth of our retail service territory is indicative of a strong core
business that will drive future financial performance. And, even in today's
battered wholesale market, our power marketing group continues to produce
positive results."

The quarter-to-quarter comparison was lower primarily due to decreased
contributions from power marketing, which contributed very strong results in the
2002 first quarter; and an increase in fixed costs related to placing three new
electricity-generating units into service in 2002.

Other factors affecting results were higher operations and maintenance and
replacement power costs related to scheduled power plant overhauls; the effects
of milder weather; higher costs for pension and other post-retirement benefits;
and a retail electricity price decrease. These negative factors were partially
offset by competitive retail sales by APS Energy Services, the Company's
competitive affiliate; and strong Arizona retail customer growth of 3.3 percent,
about three times the national average.

Despite the impact of milder weather, retail electricity sales in the first
quarter were relatively flat at 5 billion kilowatt-hours (kWh) compared with the
same period last year. First quarter wholesale power sales were 7.6 billion kWh,
up 73 percent from the 4.4 billion kWh sold in the comparable 2002 period.

PINNACLE WEST FIRST QUARTER EARNINGS                                 MAY 2, 2003
                                                                     PAGE 2 OF 2

The 1.5 percent retail price decrease, totaling about $28 million annually,
became effective July 1, 2002. Arizona Public Service (APS) plans to decrease
its retail prices another 1.5 percent this July, completing a 10-year commitment
of reducing prices a total of 16 percent for residential and small commercial
customers since 1994.

Consistent with its accelerated asset sales program, SunCor Development Co.,
Pinnacle West's real estate subsidiary, reported net income of $6.4 million,
compared with net income of $2.0 million for the prior year period. The
difference was primarily the result of SunCor's sale of its water utility
company. This sale resulted in a $5 million after-tax gain, which was recorded
as discontinued operations in accordance with the accounting standard that
classifies certain real estate activities as discontinued operations.
