    New paragraph in MD&A.

    From the filings

    Now

    In September 2026 the DOC set AD/CVD duties on imports of solar cells and panels from India, Indonesia and Laos based on findings that producers in those countries are benefiting from illegal subsidies and selling solar products below cost in the United States. The USITC is expected to make a final determination this fall. If the USITC votes affirmatively, final rates will then be issued and take effect. Further, the DOC recently began an investigation into solar panels from Ethiopia and a petition was filed requesting investigation into solar panels from South Korea, both based on similar claims that solar panels from those countries are being made with Chinese-made components in violation of AD/CVD laws.

    Now

    On August 26, 2026, President Trump issued Executive Order 14421, declaring a national emergency to protect the United States bulk-power system from security threats associated with foreign-supplied electric equipment and technology. The order authorizes the United States Secretary of Energy to restrict, evaluate, and mitigate transactions involving the installation of foreign-sourced bulk-power system components that pose certain security threats initiated after the order and to establish a framework for identifying and monitoring the same foreign-sourced components already in the domestic power infrastructure prior to this order. This order covers facilities and control systems necessary for operating an interconnected transmission network and electric generation facilities but excludes local distribution. The Executive Order requires the United States Department of Energy to publish rules or regulations implementing this order no later than 120 days from August 26, 2026, or December 24, 2026. We are currently evaluating the potential operational and financial implications of this order.

These financial statements should be read in conjunction with the consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2025. Financial results for an interim period may not give a true indication of results for the year. In particular, the results of operations for the three and six nine months ended June September 30, 2026, are not necessarily indicative of expected results for 2026 due to seasonal variations and other factors.

Note 4: CREDIT LOSSES 30 changes

Our exposure to credit losses is related to our accounts receivable and unbilled revenue balances, which are generated from the sale of electricity and natural gas by our regulated utility operations. Our regulated utility operations are included in our utility segment. No accounts receivable and unbilled revenue balances were reported in the other segment at June September 30, 2026 and December 31, 2025.

1 unchanged paragraph

We monitor our ongoing credit exposure through active review of counterparty accounts receivable balances against contract terms and due dates. Our activities include timely account reconciliation, dispute resolution and payment confirmation. To the extent possible, we work with customers with past due balances to negotiate payment plans, but will disconnect customers for non-payment as allowed by the PSCW, if necessary, and employ collection agencies and legal counsel to pursue recovery of defaulted receivables. For our larger customers, detailed credit review procedures may be performed in advance of any sales being made. We sometimes require letters of credit, parental guarantees, prepayments or other forms of credit assurance from our larger customers, including VLCs, to mitigate credit risk. See Note 21, Regulatory Environment, for more information about the Very Large Customer and Bespoke Resources Tariffs.

(1) Our exposure to credit losses for certain regulated utility customers is mitigated by a regulatory mechanism we have in place. Specifically, our residential tariffs include a mechanism for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and the amounts recovered in rates. As a result, at September 30, 2026, $ 377.9 million, or 55.8 %, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses.

Balance at September 30

There was a $ 14.0 15.2 million decrease in the allowance for credit losses at June September 30, 2025, compared to January 1, 2025. The decrease was largely driven by customer write-offs, in addition to a decrease in past due account balances that we believe was related to a continued focus on collection efforts and the lower energy bills typically seen in the spring and summer months, enabling customers to pay down their arrears. After a customer is disconnected for a period of time without payment on their account, we will write off that customer balance.

During the second quarter of 2026, we and WPS, along with an unaffiliated utility, acquired various land leases related to our investments in utility solar generation. Each lease has an initial term and one or more optional extensions. We expect the optional extensions to be exercised, and, as a result, all of the land leases are being amortized over an extended term. The weighted-average remaining lease term for these land leases was 49.3 50.1 years at June September 30, 2026. Once a solar project achieves commercial operation, the lease liability will be remeasured to reflect the final total acres being leased.

The right of use assets obtained in exchange for these finance lease liabilities was $ 38.5 38.4 million. Our total obligation under these land-related leases was $ 38.7 39.1 million at June September 30, 2026, and was included in finance lease obligations on our balance sheet. Our finance lease right of use asset related to these leases was $ 38.5 38.2 million as of June September 30, 2026, and was included in property, plant, and equipment on our balance sheet. Our weighted-average discount rate for these leases was 6.35 6.39 %. We used an estimate of the fully collateralized incremental borrowing rate based upon information available for similarly rated companies in determining the present value of lease payments.

Future minimum lease payments and the corresponding present value of our net minimum lease payments under these land-related leases as of June September 30, 2026, were as follows:

After completing its review of the 2008 ozone standard, the EPA released a final rule in October 2015, creating a more stringent standard than the 2008 NAAQS. The 2015 ozone standard lowered the 8-hour limit for ground-level ozone. The EPA's initial ozone nonattainment area designation was effective August 2018, and the attainment status is evaluated every 3 years thereafter until attainment is achieved. The Milwaukee, Sheboygan, and Chicago, IL-IN-WI nonattainment areas did not meet the marginal attainment deadline of August 2021, so in April 2022 the EPA proposed "moderate" nonattainment status based on the 2015 standard.

In February 2025, the Wisconsin Department of Natural Resources submitted a State Implementation Plan to the EPA recommending Wisconsin be designated as an attainment area under the 2024 PM2.5 Standard. The EPA has not yet issued its attainment designations. and has indicated it may extend the designation period by 1 year due to A lack of adequate air monitoring data. A designation of nonattainment status could impact future permitting activities for facilities in applicable locations, including the potential need for improved or new air pollution control equipment. With our planned transition from coal-fired plants to natural gas-fired plants and renewable generating facilities, We do not expect the 2024 PM2.5 Standard to have a material impact on our units.

In November 2025, the EPA filed a motion in the litigation pending in the D.C. Circuit Court of Appeals to vacate the 2024 PM2.5 Standard.
