I. Executive Summary

This memorandum addresses a significant development in the pending acquisition of Cascadia Renewables Holdings, Inc. ("Cascadia" or the "Company") by Cascadia Acquisition Corp. (the "Buyer"), a special-purpose entity jointly controlled by Meridian Infrastructure Partners LP ("Meridian" or "Fund IV") and ICM Cascadia Co-Invest, LP ("ICM Co-Invest"), of which Ironside Capital Management LP ("Ironside" or "ICM") is the 99.99% limited partner.

On October 28, 2022, the Portland Metropolitan Water District (the "Water District") notified Cascadia that it intended to exercise its contractual right to renegotiate the 40-year water-treatment concession for the Bull Run Filtration Project (the "Bull Run Concession"), originally executed in 2018. The Water District's stated basis for the renegotiation notice is changed regulatory requirements under Oregon Senate Bill 1567 ("Oregon SB 1567" or "SB 1567"), a state law enacted during the 2022 legislative session imposing new treatment standards, monitoring obligations, and reporting requirements on water-treatment facilities operating under long-term concession or public-private-partnership arrangements.

On November 10, 2022, Meridian Infrastructure Partners LP, through its outside counsel, Breckenridge Sloane & Pratt LLP (Charles A. Delacroix, partner), notified Ironside of this development, characterizing it as a material development potentially affecting the Cascadia acquisition and Ironside's co-investment commitment.

This memorandum analyzes whether the concession renegotiation constitutes a "Material Adverse Effect" ("MAE") as defined in Article I of the Equity Purchase Agreement (the "EPA") dated September 15, 2022, among the Selling Shareholders (Timberline Growth Equity Fund III, LP, the Weir Family Trust, and the Management Rollover Pool), Cascadia Renewables Holdings, Inc., and Cascadia Acquisition Corp. Specifically, we examine the operative MAE definition, the enumerated carve-outs, the quantitative and qualitative dimensions of the concession renegotiation, and the implications for the closing conditions, Ironside's co-investment position, and the representations and warranty insurance policy.

Summary Conclusion. The concession renegotiation presents a strong factual basis for asserting that an MAE has occurred or is reasonably likely to occur. The Bull Run Concession generates approximately $64 million in annual revenue, representing approximately 13.1% of Cascadia's FY 2021 total revenue of $487 million, and an estimated $18–22 million in annual EBITDA contribution, representing approximately 13–16% of total FY 2021 EBITDA of $138 million. The long-duration nature of the concession (approximately 36 years remaining) amplifies the significance of any adverse modification to its economic terms.

However, the analysis is materially complicated by several carve-outs in the EPA's MAE definition. The regulatory-change carve-out and the industry-wide-effects carve-out are the most significant analytical obstacles to an MAE assertion. The applicability of these carve-outs turns on factual and interpretive questions that are not fully resolvable on the present record, including (a) whether Oregon SB 1567 constitutes a "change in law" occurring after the EPA execution date (given that SB 1567 was enacted and took effect before September 15, 2022), (b) whether the Water District's renegotiation notice is properly characterized as a regulatory action or a contractual counterparty action, and (c) whether SB 1567's effects are industry-wide or disproportionately affect Cascadia relative to other similarly situated water-treatment concession holders.

Additionally, the renegotiation is in its earliest stages and may result in modified — rather than terminated — concession terms. Delaware courts have historically set a high bar for MAE findings, requiring evidence of a material adverse impact on the target's earnings potential measured over a commercially reasonable period, and have been reluctant to find an MAE based on ongoing developments whose ultimate impact remains uncertain.

Recommendation. We recommend that Ironside preserve its rights to assert an MAE but refrain from doing so at this time. Ironside should instruct Calderwood & Harkness LLP ("C&H") to deliver a formal reservation-of-rights letter to Meridian's counsel and should request regular updates on the renegotiation's progress. The MAE analysis should be reassessed as new facts emerge, including any proposed renegotiated terms, changes in the scope of the renegotiation, or indications of the Water District's ultimate position. This reassessment should occur, at minimum, at each decision point concerning the extension of the EPA's outside date.

II. Factual Background

A. The Bull Run Filtration Project Concession

Cascadia Renewables Holdings, Inc. holds a 40-year water-treatment concession with the Portland Metropolitan Water District for the Bull Run Filtration Project, a large-scale water-treatment and filtration facility serving portions of the Portland metropolitan area's municipal water supply. The concession was originally executed in approximately 2018, following a competitive procurement process conducted by the Water District. Under the terms of the concession agreement, Cascadia is responsible for the design, construction, financing, operation, and maintenance of the Bull Run Filtration Project in exchange for availability-based payments and volume-based fees from the Water District over the 40-year concession term.

Annual revenue generated under the Bull Run Concession is approximately $64 million. This figure is based on FY 2021 audited financial data and reflects a combination of fixed availability payments and variable throughput-based fees. The concession payment structure is subject to annual escalation provisions tied to a blended index of the Consumer Price Index and a construction-cost index, providing a degree of inflation protection that has been a key feature of the concession's economic profile.

The Bull Run Concession is one of three water-treatment concessions operated by Cascadia across the Pacific Northwest. The other two are (i) a 30-year concession with the Spokane Regional Water Authority in Washington State, generating approximately $28 million in annual revenue, and (ii) a 25-year concession with the Boise Municipal Water Board in Idaho, generating approximately $19 million in annual revenue. Collectively, Cascadia's water-treatment concession portfolio represents approximately $111 million in annual revenue. The Bull Run Concession is the largest of these three contracts by a significant margin, accounting for approximately 58% of water-treatment concession revenue and approximately 13.1% of total Cascadia revenue.

Cascadia's total FY 2021 revenue, as reported in the audited financial statements prepared by Halstead & Greer LLP, was $487 million. FY 2021 EBITDA was $138 million, reflecting an overall EBITDA margin of approximately 28.3%. Cascadia's operations span 14 hydroelectric facilities, 6 wind farms, and 3 water-treatment concessions across Oregon, Washington, Idaho, and Montana. The Company's business model is centered on long-duration infrastructure concessions and power-purchase agreements, and the investment thesis supporting the agreed enterprise value of $1.95 billion relies substantially on the stability, predictability, and long weighted-average remaining contract life of these revenue streams.

Assuming that the Bull Run Concession generates EBITDA at margins comparable to Cascadia's overall average, the concession's estimated annual EBITDA contribution is in the range of $18–22 million, representing approximately 13–16% of total FY 2021 EBITDA. We note that the actual EBITDA margin on the Bull Run Concession may differ from the overall average due to the capital-intensive nature of the facility and the specific cost structure associated with water-treatment operations; however, in the absence of segment-level margin data (which has not been disclosed to Ironside at this time), the blended-margin assumption provides a reasonable approximation.

The Bull Run Concession is among Cascadia's longest-duration contracts. With approximately 36 years remaining on the concession term as of the date of this memorandum, the Bull Run Concession contributes significantly to the portfolio-wide weighted-average remaining contract life of approximately 22 years, which is a critical metric for infrastructure investors and a key driver of the valuation multiple applied to Cascadia's earnings in the transaction.

B. The Renegotiation Notice

On October 28, 2022, the Portland Metropolitan Water District issued a formal written notice to Cascadia of its intent to renegotiate the terms of the Bull Run Concession (the "Renegotiation Notice"). The notice was addressed to Cascadia's Chief Executive Officer and General Counsel and was delivered by both certified mail and electronic transmission.

The stated basis for the Renegotiation Notice is changed regulatory requirements under Oregon SB 1567, a state law enacted during the 2022 legislative session. Oregon SB 1567, which took effect on July 1, 2022, imposes new standards for water-treatment facilities operating under long-term concession or public-private-partnership arrangements, including enhanced treatment standards, expanded monitoring and reporting requirements, mandatory capital-improvement plans to meet updated environmental and public-health benchmarks, and new community-engagement and transparency obligations. The Water District's notice cites Section 14 of the Bull Run Concession Agreement, which provides a renegotiation right in the event of "material changes in applicable law that substantially alter the regulatory environment governing the Facility's operations or the District's obligations to the public."

Renegotiation was formally opened in November 2022, following the delivery of the notice. As of the date of this memorandum, no resolution or preliminary framework for renegotiated terms has been proposed by either party. The scope of the renegotiation is not fully defined in the notice, and the Water District has indicated only that it intends to address, among other things, compliance with the new regulatory standards, allocation of capital-expenditure obligations associated with facility upgrades, potential modifications to the pricing structure to reflect changed cost burdens, and possible adjustments to performance standards and default provisions. The renegotiation could encompass pricing terms, performance standards, capital-expenditure obligations, term adjustments, or a combination thereof, and the range of potential outcomes is correspondingly broad.

We have not been provided with a copy of the underlying Bull Run Concession Agreement and are relying on the description of its terms as set forth in the EPA disclosure schedules, the Renegotiation Notice (a copy of which was provided to Ironside by Meridian's counsel on November 10, 2022), and discussions with Ironside's internal team. We have requested a complete copy of the concession agreement from Meridian's counsel, and this request is pending as of the date of this memorandum. Access to the full concession agreement is important for several aspects of our analysis, including the scope and triggers of the renegotiation right, the availability of dispute-resolution mechanisms, and the interplay between the concession agreement's force majeure and regulatory-change provisions and the EPA's MAE definition.

C. Transaction Context

The Cascadia acquisition is structured as a 100% equity acquisition. Under the EPA, Cascadia Acquisition Corp., a Delaware corporation organized solely for the purpose of the acquisition and wholly owned by Fund IV and ICM Co-Invest, will acquire all of the outstanding equity interests of Cascadia from the Selling Shareholders. The Selling Shareholders consist of Timberline Growth Equity Fund III, LP (holding approximately 72% of Cascadia's equity), the Weir Family Trust (holding approximately 18%), and the Management Rollover Pool (holding approximately 10%, a portion of which will be rolled over into equity in the post-closing entity).

The agreed enterprise value of Cascadia under the EPA is $1,950,000,000. This implies an EV/EBITDA multiple of approximately 14.1x based on FY 2021 EBITDA of $138 million, as reflected in the audited financial statements prepared by Halstead & Greer LLP. The 14.1x multiple reflects a premium to the broader water and renewable-energy infrastructure sector, attributable principally to the length and quality of Cascadia's contracted revenue streams, the inflation-linked escalation provisions embedded in the Company's concession and power-purchase agreements, and the favorable regulatory environment in the Pacific Northwest.

Total equity committed to the acquisition is $1,050,000,000, structured as follows:

• Meridian Infrastructure Partners Fund IV, LP: $750,000,000 (71.43% of total equity)

• ICM Cascadia Co-Invest, LP: $300,000,000 (28.57% of total equity)

The acquisition is financed in part with third-party debt. The senior secured credit facility consists of a $975 million senior secured term loan, arranged by Atlas National Bank, N.A., which serves as the lead arranger and administrative agent (holding a $650 million commitment), and Pinnacle Credit Partners LLC (holding a $325 million commitment). In addition, a $150 million revolving credit facility has been committed by Atlas National Bank (fully undrawn as of the date of this memorandum). The debt commitment letter was executed on August 22, 2022, and the funding of the term loan is subject to customary conditions precedent, including the absence of a material adverse effect as defined in the credit agreement (which contains its own MAE definition, analyzed in a separate C&H memorandum dated August 30, 2022).

The EPA was executed on September 15, 2022. The original outside date — the date by which the closing must occur, failing which either party may terminate the EPA — is December 31, 2022. We understand from discussions with Ironside and with Meridian's counsel that an extension of the outside date to March 31, 2023, is under active consideration and is the subject of a proposed First Amendment to the EPA. The First Amendment is analyzed in a separate C&H memorandum dated November 20, 2022.

ICM Cascadia Co-Invest, LP has issued a single capital call dated August 15, 2022, in the amount of $22,500,000, representing 7.5% of Ironside's total commitment of $300,000,000 (Ironside's 99.99% LP share being $299,970,000, with the remaining $30,000 attributable to Meridian Infrastructure GP IV LLC's general-partner interest). The unfunded commitment of $277,500,000 remains subject to future capital calls in accordance with the terms of the Limited Partnership Agreement of ICM Cascadia Co-Invest, LP (the "LP Agreement") dated July 29, 2022.

III. Material Adverse Effect Definition Under the EPA

A. Text of the MAE Definition

The operative MAE definition is set forth in Section 1.01 of the EPA, within the defined terms of Article I. As is standard in negotiated acquisition agreements of this nature, the MAE definition consists of two principal components: (i) an affirmative definition of what constitutes an MAE, and (ii) a series of enumerated carve-outs specifying categories of events, changes, or effects that are excluded from the definition regardless of their adverse impact.

The affirmative definition follows the standard formulation prevalent in Delaware-law-governed acquisition agreements. Specifically, Section 1.01 of the EPA defines a "Material Adverse Effect" as:

"any event, change, effect, development, condition, or occurrence that, individually or in the aggregate with all other events, changes, effects, developments, conditions, or occurrences, has had or would reasonably be expected to have a material adverse effect on (a) the business, assets, liabilities, financial condition, or results of operations of the Company and its Subsidiaries, taken as a whole, or (b) the ability of the Selling Shareholders or the Company to consummate the transactions contemplated by this Agreement."

Several features of this definition warrant particular attention in the context of the present analysis.

First, the definition encompasses not only effects that "have had" a material adverse impact but also those that "would reasonably be expected to have" such an impact. This forward-looking element is critical in the concession-renegotiation context because the renegotiation has not yet produced any definitive economic impact — no renegotiated terms have been proposed or agreed. The question is whether the initiation of the renegotiation process, and the attendant risk of materially adverse renegotiated terms, is sufficient to satisfy the "reasonably expected" standard.

Second, the definition applies to effects considered "individually or in the aggregate." This aggregation principle means that the concession renegotiation need not independently satisfy the materiality threshold; it may be combined with other adverse developments affecting Cascadia to reach the MAE standard. We are not aware of other material adverse developments at this time, but we note this provision for completeness.

Third, the qualifier "taken as a whole" requires that the effect be material to the entire Cascadia enterprise, not merely to a single contract or business line. This is a significant analytical consideration because Cascadia is a diversified infrastructure platform operating 14 hydroelectric facilities, 6 wind farms, and 3 water-treatment concessions. An adverse development affecting one concession, even one as significant as the Bull Run Concession, must be evaluated in the context of the enterprise as a whole.

Fourth, the definition includes a second limb — clause (b) — addressing effects on the ability of the Selling Shareholders or the Company to consummate the transactions. This limb is less likely to be directly implicated by the concession renegotiation (which does not, on its face, affect the parties' ability to close), but it could become relevant if the renegotiation affects the lenders' willingness to fund under the debt commitment letter, thereby indirectly impeding closing.

B. Enumerated Carve-Outs

The MAE definition contains six enumerated carve-outs, each specifying a category of event, change, or effect that is excluded from the MAE definition. We analyze each carve-out below in the context of the concession renegotiation.

1. Regulatory/Legislative Change Carve-Out

The first carve-out excludes from the MAE definition:

any effect arising from or relating to changes in applicable law, rules, regulations, orders, or other binding directives issued by any governmental authority, or changes in the interpretation or enforcement thereof, in each case occurring after the date of this Agreement.

This carve-out is directly relevant to the concession renegotiation and is likely to be the central battleground in any dispute over whether an MAE has occurred.

The threshold question is whether Oregon SB 1567 constitutes a "change in applicable law" occurring "after the date of this Agreement." The EPA was executed on September 15, 2022. Oregon SB 1567 was enacted during the 2022 legislative session and took effect on July 1, 2022 — more than two months before the EPA execution date. On its face, SB 1567 appears to be a pre-existing regulatory condition at the time the EPA was signed, not a post-signing "change" in applicable law.

However, the analysis is not straightforward. Several sub-issues warrant detailed examination.

Timing of the Change in Law. The text of the carve-out limits its application to changes "occurring after the date of this Agreement." The enactment and effective date of Oregon SB 1567 both precede the EPA date. Under a plain-reading approach, the statute does not qualify as a change in law occurring after September 15, 2022, and the carve-out would not apply to shield the renegotiation from the MAE definition.

Downstream Effects of a Pre-EPA Regulatory Change. The sellers are likely to argue that even though SB 1567 itself predates the EPA, the effects of the statute — including the Water District's exercise of its contractual renegotiation right — are properly characterized as effects "arising from or relating to" a change in law. Under this reading, the carve-out would be triggered not by the timing of the statute's enactment but by the causal connection between the regulatory change and the adverse effect on Cascadia. This argument has some textual support in the "arising from or relating to" language, which is broad and potentially encompasses downstream consequences of a statutory change even if the statute itself predates the agreement.

Counterargument: Pre-Existing Conditions and the Signing-Date Baseline. Under standard MAE analysis, the date of the agreement establishes the baseline against which materiality is measured. Pre-existing conditions — including laws already enacted and in effect — are part of the baseline. Changes in the target's business that flow from pre-existing conditions generally are not shielded by the regulatory-change carve-out because the carve-out is designed to protect sellers from the risk of post-signing regulatory developments, not from the realization of risks that existed at the time of signing. Under this reasoning, SB 1567 was a known regulatory condition at the time the EPA was executed, and its effects — including the possibility that the Water District would exercise its renegotiation right — were part of the landscape against which the parties struck their bargain. The sellers (and their counsel at Morgan Cross & Whitfield LLP) would have been aware of SB 1567 at the time the EPA was negotiated and executed, and the failure to disclose or address the renegotiation risk in the EPA may itself be significant.

The Renegotiation Right as Contractual, Not Regulatory. An additional analytical layer concerns the characterization of the Water District's action. The Renegotiation Notice invokes Section 14 of the Bull Run Concession Agreement — a contractual provision permitting renegotiation upon specified regulatory changes. The Water District is not exercising a legislative or regulatory power; it is exercising a contractual right under a pre-existing concession agreement. If the renegotiation right is properly characterized as a contractual action by a counterparty rather than a change in law per se, the regulatory-change carve-out may not apply even if SB 1567 is treated as the underlying cause.

This distinction — between the regulatory trigger and the contractual mechanism through which the adverse effect operates — is analytically significant. The carve-out addresses changes in "applicable law"; it does not expressly address contractual actions taken in response to changes in law. Courts interpreting similar carve-outs have generally focused on the proximate cause of the adverse effect rather than its ultimate or root cause. Under this approach, the proximate cause of the adverse effect on Cascadia is the Water District's exercise of its contractual renegotiation right, not the enactment of SB 1567, and the carve-out should not apply.

Disproportionate Impact Exception. The regulatory-change carve-out contains a standard proviso excepting from the carve-out any effect that "disproportionately affects the Company and its Subsidiaries, taken as a whole, relative to other participants in the industries in which the Company and its Subsidiaries operate." This exception is discussed in detail in Section III.C below.

2. Industry-Wide Effects Carve-Out

The second carve-out excludes from the MAE definition:

any effect generally affecting the industries or markets in which the Company and its Subsidiaries operate, including changes in prevailing interest rates, commodity prices, or market valuations.

This carve-out is relevant to the extent that Oregon SB 1567 affects the water-infrastructure concession industry broadly rather than Cascadia specifically. If the statute imposes new requirements on all water-treatment concession holders in Oregon, and if renegotiation notices have been issued (or are reasonably expected to be issued) to other concession holders, the adverse effects may be characterized as industry-wide and thus excluded from the MAE definition.

Our analysis of this carve-out requires factual information that is not fully available as of the date of this memorandum. The key factual questions include: How many other water-treatment concession holders operate in Oregon under similar long-term concession or public-private-partnership arrangements? Have other municipal counterparties issued renegotiation notices in response to SB 1567? Is the Bull Run Concession unique in its susceptibility to renegotiation under the statute, or is the renegotiation risk broadly shared across the Oregon water-infrastructure concession market?

If SB 1567 affects the industry broadly and other concession holders face comparable renegotiation risks, the industry-wide-effects carve-out would shelter the sellers, subject to the disproportionate-impact exception. If, conversely, the Bull Run Concession is uniquely affected — for example, because of the specific terms of its concession agreement, the particular regulatory requirements applicable to the Bull Run Filtration Project, or the Water District's unique position among Oregon municipal water authorities — the industry-wide carve-out may not apply.

We recommend that Ironside request from Meridian detailed factual information regarding the impact of SB 1567 on other water-treatment concessions in Oregon, including whether other municipal counterparties have issued renegotiation notices or indicated an intent to do so.

3. General Economic and Market Conditions Carve-Out

The EPA carves out from the MAE definition:

any effect arising from or relating to general economic, political, financial, or market conditions, including changes in prevailing interest rates, currency exchange rates, credit markets, capital markets, or equity markets.

This carve-out is unlikely to be directly applicable to the concession renegotiation, which is driven by a specific regulatory development (Oregon SB 1567) and a specific counterparty action (the Water District's renegotiation notice) rather than by general economic or market conditions. We note this carve-out for completeness but do not consider it a significant analytical factor in the present context.

4. Acts of Government / Regulatory Action Carve-Out

The EPA contains a carve-out for:

any effect arising from or relating to any action taken by any governmental authority, including any legislative, regulatory, or judicial action or any enforcement action, in each case of general applicability.

This carve-out overlaps with and supplements the regulatory-change carve-out discussed in Section III.B.1 above. Its applicability to the concession renegotiation turns on two questions: (a) whether the Portland Metropolitan Water District's renegotiation notice constitutes an "action taken by any governmental authority" and (b) whether the action is "of general applicability."

The Portland Metropolitan Water District occupies a dual role: it is both a municipal governmental body and a contractual counterparty to Cascadia under the Bull Run Concession Agreement. When the Water District issues a renegotiation notice pursuant to a contractual provision in the concession agreement, it is acting in its capacity as a contracting party — not in its regulatory or legislative capacity. The action is specific to the Bull Run Concession Agreement and is directed at Cascadia as the concessionaire, not at the industry at large. Under this characterization, the governmental-action carve-out may not apply because the Water District's action is neither a regulatory action nor an action of general applicability.

However, the sellers may argue that the Water District's action is properly understood as a governmental action because the Water District is a municipal body exercising a right triggered by legislative action (SB 1567), and that the nature of the Water District's action cannot be divorced from its governmental character. This argument is stronger if the Water District's renegotiation right is viewed as an implementing mechanism for SB 1567 rather than an independent contractual action.

The "general applicability" limitation is an additional obstacle for the sellers. Even if the Water District's action is characterized as governmental, it is specific to the Bull Run Concession and is not of general applicability. The carve-out, by its terms, applies only to governmental actions "of general applicability."

5. Pandemic / Force Majeure Carve-Out

The EPA excludes from the MAE definition effects arising from pandemics, epidemics, disease outbreaks, or natural disasters. This carve-out is not applicable to the concession renegotiation and is noted solely for completeness.

6. Transaction-Related Carve-Out

The EPA carves out:

any effect arising from or attributable to the announcement or pendency of the transactions contemplated by this Agreement, including any loss of, or change in the relationship with, any customer, supplier, employee, or business partner resulting therefrom.

This carve-out is designed to insulate sellers from adverse effects caused by the announcement of the acquisition itself — such as customer defections, employee departures, or supplier renegotiations triggered by uncertainty about the target's post-acquisition ownership. The concession renegotiation was triggered by Oregon SB 1567, not by the announcement or pendency of the Cascadia acquisition. There is no factual basis for concluding that the Water District's renegotiation notice was motivated by or related to the acquisition. Accordingly, this carve-out is not directly relevant to the present analysis.

C. Interaction of Carve-Outs with "Disproportionate Impact" Exception

Most of the carve-outs in the MAE definition — including the regulatory-change carve-out, the industry-wide-effects carve-out, and the general-economic-conditions carve-out — contain a proviso commonly known as the "disproportionate impact" exception. The EPA's version of this proviso states:

provided, however, that with respect to clauses (i) through (iv) above, such events, changes, effects, developments, conditions, or occurrences shall be taken into account in determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur to the extent that such events, changes, effects, developments, conditions, or occurrences have a disproportionate adverse effect on the Company and its Subsidiaries, taken as a whole, relative to other participants in the industries in which the Company and its Subsidiaries operate.

The disproportionate-impact exception is the analytical mechanism by which carve-outs that would otherwise shield the sellers can be overridden. Even if the concession renegotiation is caused by a regulatory change (SB 1567) or constitutes an industry-wide effect, the MAE definition is reinstated if the renegotiation disproportionately affects Cascadia relative to other participants in the water-infrastructure concession industry.

The disproportionate-impact analysis requires a factual comparison of Cascadia's situation with that of other similarly situated companies. The relevant comparator group would consist of other companies holding long-term water-treatment concessions in Oregon (and potentially the broader Pacific Northwest). Key factual questions include:

(a) How many other water-treatment concessions in Oregon are subject to SB 1567? Are there other concessions of comparable size and duration?

(b) Have other municipal water authorities issued renegotiation notices to their concessionaires in response to SB 1567? If not, is the Water District's action unique to Cascadia's Bull Run Concession?

(c) Does the Bull Run Concession Agreement contain renegotiation provisions that are more favorable to the Water District than comparable provisions in other concession agreements? Is the contractual trigger for renegotiation in Section 14 of the Bull Run Concession Agreement unusual or industry-standard?

(d) Does Cascadia hold a unique or outsized position in the Oregon water-treatment concession market such that SB 1567's impact falls disproportionately on Cascadia?

If Cascadia is the only concession holder — or one of a very small number — to receive a renegotiation notice, or if the economic impact of the renegotiation is proportionally greater for Cascadia than for other concession holders, the disproportionate-impact exception would apply, and the regulatory-change and industry-wide carve-outs would not shield the sellers.

Conversely, if SB 1567 has triggered renegotiation notices across the industry, and the economic impact on Cascadia is proportionate to the impact on other concession holders, the disproportionate-impact exception would not apply, and the carve-outs would protect the sellers.

We do not have sufficient factual information to resolve this question definitively at this time and recommend that Ironside pursue the factual inquiries outlined above through Meridian and, if necessary, through independent research or consultants familiar with the Oregon water-infrastructure market.

IV. Quantitative Materiality Analysis

A. Revenue Impact

The Bull Run Concession generates approximately $64 million in annual revenue. Cascadia's total FY 2021 revenue, as reflected in the audited financial statements, was $487 million. The Bull Run Concession therefore represents approximately 13.1% of Cascadia's total revenue.

However, the mere existence of the renegotiation does not necessarily mean that the entire $64 million revenue stream is at risk. The range of potential outcomes from the renegotiation spans from modest pricing adjustments to significant term modifications to (at the extreme, and we believe unlikely) termination of the concession. Each of these outcomes carries a different quantitative implication for the MAE analysis.

We have modeled three representative scenarios below:

Scenario 1 — Modest Adjustment. If the renegotiation results in a modest pricing adjustment — for example, a 5–10% reduction in annual concession revenue to reflect the Water District's increased regulatory costs under SB 1567 — the annual revenue impact would be approximately $3.2 million to $6.4 million. This represents approximately 0.7% to 1.3% of total Cascadia revenue. An impact of this magnitude would be unlikely to constitute an MAE on quantitative grounds alone, even taking into account the long-duration nature of the concession (36 years remaining). The net present value of a $3.2–6.4 million annual reduction over 36 years, discounted at a reasonable cost of capital, would represent a meaningful but not necessarily material reduction in enterprise value.

Scenario 2 — Significant Renegotiation. If the renegotiation results in a significant reduction in concession economics — for example, a 25–40% reduction in annual concession revenue, reflecting substantial modifications to pricing terms, additional capital-expenditure obligations, or other economic concessions by Cascadia — the annual revenue impact would be approximately $16 million to $25.6 million. This represents approximately 3.3% to 5.3% of total Cascadia revenue. An impact of this magnitude falls into an analytically ambiguous range. Depending on the durational significance and other qualitative factors, it could support an MAE assertion, but the case would not be clear-cut.

Scenario 3 — Concession Termination or Fundamental Restructuring. In the most adverse scenario — a termination of the concession, a constructive repudiation by the Water District, or a fundamental restructuring of the concession that eliminates the majority of its economic value — the full $64 million annual revenue stream would be at risk. This represents approximately 13.1% of total Cascadia revenue. An impact of this magnitude presents a substantially stronger quantitative case for an MAE, particularly given the long remaining term of the concession and the centrality of the Bull Run Concession to Cascadia's contracted revenue portfolio.

We emphasize that these scenarios are illustrative and that the actual outcome of the renegotiation remains highly uncertain at this early stage.

B. EBITDA Impact

Translating the revenue-impact analysis into EBITDA terms, and assuming that the Bull Run Concession operates at margins comparable to Cascadia's overall average EBITDA margin of approximately 28.3% ($138 million EBITDA on $487 million revenue), the estimated EBITDA contribution of the Bull Run Concession is approximately $18–22 million per year. We present a range rather than a point estimate because we do not have segment-level financial data for the Bull Run Concession and recognize that the actual margin may differ from the blended corporate average.

The impact on implied enterprise value, at the agreed 14.1x EV/EBITDA multiple, is significant:

Under a full-loss scenario, the implied reduction in enterprise value of $254–310 million represents a substantial impairment — roughly 13% to 16% of the agreed enterprise value of $1.95 billion. Under a significant-renegotiation scenario, the implied reduction of $63–124 million, while meaningful, represents a smaller percentage of enterprise value and may not meet the quantitative threshold for an MAE under prevailing Delaware precedent.

C. Case Law and Precedent on Quantitative Thresholds

Delaware courts have not established a bright-line quantitative threshold for MAE determinations, but the case law provides useful guidance on the range of quantitative impacts that have been found sufficient — or insufficient — to constitute an MAE.

The Delaware Court of Chancery's decision in Akorn, Inc. v. Fresenius Kabi AG (2018) remains the leading authority on MAE analysis. In Akorn, the court found an MAE based on, among other factors, a sustained decline in earnings of approximately 50–60%, combined with evidence that the decline was durable and resulted from systematic regulatory compliance failures rather than temporary market conditions. The Akorn court emphasized that an MAE requires a significant adverse impact on the target's earnings potential measured over a "commercially reasonable period," which the court characterized as a period of years rather than months.

Prior Delaware decisions — including the Court of Chancery's earlier opinions in IBP, Inc. v. Tyson Foods (2001) and Hexion Specialty Chemicals, Inc. v. Huntsman Corp. (2008) — similarly set a high bar for MAE findings. In IBP, the court declined to find an MAE based on a 64% decline in quarterly earnings, characterizing the decline as a short-term fluctuation inconsistent with the durational expectations inherent in the MAE standard. In Hexion, the court's analysis focused on the long-term impact of the alleged adverse developments on the target's business prospects, again emphasizing that temporary or cyclical downturns do not constitute MAEs.

The general framework that emerges from the Delaware case law can be summarized as follows:

(a) Impacts of approximately 40% or more of earnings, sustained over a commercially reasonable period, are generally regarded as sufficient to constitute an MAE.

(b) Impacts in the range of 10–20% of earnings fall into an analytically ambiguous "gray zone" in which the MAE determination depends heavily on the durational significance, the qualitative nature of the adverse development, and the overall context.

(c) Impacts below approximately 10% of earnings are generally regarded as insufficient to constitute an MAE in the absence of extraordinary qualitative circumstances.

The 13.1% revenue-at-risk figure (and the corresponding 13–16% EBITDA-at-risk estimate) places this situation squarely in the gray zone under prevailing Delaware precedent if the full concession revenue is lost. Scenarios involving partial renegotiation — particularly the modest-adjustment scenario — are likely to fall below the quantitative threshold. Scenarios involving significant renegotiation are analytically uncertain and would require strong qualitative arguments (including durational significance and centrality to the investment thesis) to support an MAE determination.

D. Durational Significance

The Bull Run Concession is a 40-year contract with approximately 36 years remaining as of the date of this memorandum. Any material modification to the concession's economic terms would have implications extending over decades — well beyond the "commercially reasonable period" contemplated by the Delaware courts' durational-significance standard. This factor strongly favors an MAE finding in the event of a materially adverse renegotiation outcome.

The long-duration nature of the concession means that even a relatively modest annual revenue reduction, compounded over the remaining 36-year term, produces a large aggregate impact. For example, a 25% reduction in annual concession revenue ($16 million per year) over 36 years represents $576 million in aggregate undiscounted lost revenue and approximately $180–220 million in net-present-value terms at a discount rate of 7–9% — a significant fraction of the agreed enterprise value.

However, we note an important caveat: the renegotiation itself is in its earliest stages. No renegotiated terms have been proposed or agreed, and the ultimate outcome remains highly uncertain. Delaware courts have generally been reluctant to find an MAE based on ongoing developments whose final impact is not yet known. The IBP court emphasized the importance of "known rather than projected circumstances" in the MAE analysis, and the Akorn court required evidence of a "durationally significant" impact before concluding that an MAE had occurred. An ongoing renegotiation, by its nature, does not yet demonstrate the kind of durable, realized impact that Delaware courts have required.

This tension — between the potentially large long-term impact and the present uncertainty about the outcome — is a central challenge in the current MAE analysis and reinforces our recommendation that Ironside preserve its rights but refrain from asserting an MAE at this time.

V. Application of MAE Analysis to the Concession Renegotiation

A. Arguments Supporting an MAE Finding

We identify the following principal arguments supporting the conclusion that the concession renegotiation constitutes an MAE or is reasonably likely to result in one:

1. Magnitude of Revenue at Risk. The Bull Run Concession generates approximately $64 million in annual revenue, representing approximately 13.1% of Cascadia's total FY 2021 revenue. Even under a partial-renegotiation scenario, the revenue at risk is substantial, and the potential EBITDA impact ($18–22 million annually in a full-loss scenario) is meaningful relative to Cascadia's total EBITDA of $138 million. As discussed in Section IV above, the quantitative impact, while not clearly above the threshold established in the Delaware case law, falls within the range that courts have treated as analytically significant.

2. Durational Significance. The concession has approximately 36 years remaining on its term. Any adverse modification to the concession's economics would persist for decades, producing a large cumulative impact. This factor strongly favors an MAE finding under the durational-significance framework established by the Delaware courts.

3. Centrality of Bull Run to the Investment Thesis. The Bull Run Filtration Project is Cascadia's single largest water-treatment concession and one of the crown jewels of the Company's contracted revenue portfolio. The concession was a significant driver of the agreed enterprise value of $1.95 billion and the premium 14.1x EV/EBITDA multiple. The investment thesis supporting Ironside's $300 million co-investment commitment relied, in significant part, on the stability and predictability of the Bull Run revenue stream over the remaining concession term. A material impairment of this revenue stream would fundamentally alter the risk-return profile of the investment.

4. Regulatory-Change Carve-Out May Not Apply. As analyzed in detail in Section III.B.1 above, Oregon SB 1567 was enacted and took effect before the EPA execution date of September 15, 2022. Under a plain-reading approach, SB 1567 does not constitute a change in law occurring "after the date of this Agreement" and is not covered by the regulatory-change carve-out. Moreover, the proximate cause of the adverse effect on Cascadia is the Water District's exercise of a contractual renegotiation right under the Bull Run Concession Agreement — a counterparty action, not a change in law.

5. Disproportionate Impact Argument. If the Bull Run Concession is uniquely affected by SB 1567 — for example, because the Bull Run Concession Agreement contains broader renegotiation triggers than other Oregon water-treatment concessions, or because the Bull Run Filtration Project faces more extensive compliance requirements under SB 1567 than other facilities — the disproportionate-impact exception to the carve-outs would apply, reinstating the MAE definition. Ironside should pursue the factual inquiries necessary to evaluate this argument.

B. Arguments Against an MAE Finding (Sellers' Likely Position)

We anticipate that the Selling Shareholders, through their counsel at Morgan Cross & Whitfield LLP, would advance the following arguments in response to an MAE assertion:

1. Regulatory-Change Carve-Out. The sellers' strongest argument is that Oregon SB 1567 constitutes a change in applicable law and that the concession renegotiation flows directly from that regulatory change. Sellers will argue that the carve-out's "arising from or relating to" language is broad enough to encompass the downstream effects of the statute, including the Water District's exercise of a contractual renegotiation right triggered by the regulatory change. They may characterize the Water District's notice as the natural and foreseeable regulatory consequence of SB 1567, rather than an independent contractual action.

2. Industry-Wide Effects. Sellers may argue that SB 1567 affects all water-treatment concession holders in Oregon, making the concession renegotiation an industry-wide effect sheltered by the industry-wide-effects carve-out. If other concession holders are similarly affected, the impact on Cascadia is not unique to the Company but rather a shared condition of the industry.

3. No Disproportionate Impact. Sellers will contend that Cascadia is not disproportionately affected by SB 1567 relative to other similarly situated companies. If other Oregon water-treatment concession holders face comparable renegotiation risks, the disproportionate-impact exception does not apply.

4. Renegotiation Does Not Equal Termination. The sellers will emphasize that the concession has not been terminated, repudiated, or fundamentally impaired. A renegotiation may result in modified terms that preserve significant economic value for Cascadia. The sellers may point to the possibility of favorable renegotiation outcomes — such as a modest pricing adjustment, a term extension, or a rebalancing of capital-expenditure obligations — that would mitigate the economic impact.

5. Prematurity. No renegotiation outcome has been reached. Asserting an MAE at this early stage — before any proposed terms have been put forward — is inherently speculative and premature. Delaware courts have consistently required evidence of a realized or reasonably ascertainable adverse impact, not merely the initiation of a process that may or may not result in adverse outcomes.

6. Quantitative Threshold Not Clearly Met. The sellers will argue that a 13.1% revenue impact (and the corresponding 13–16% EBITDA impact) does not satisfy the high quantitative bar set by Delaware courts for MAE findings. Citing IBP and the pre-Akorn case law, the sellers will contend that impacts below approximately 40% of earnings are presumptively insufficient to constitute an MAE, and that the 13.1% figure falls well below this threshold.

7. "Taken as a Whole" Qualifier. Cascadia is a diversified infrastructure platform with operations spanning hydroelectric, wind, and water-treatment assets across four states. The Bull Run Concession, while significant, is one of 23 operating assets. The sellers will argue that the impact of the renegotiation must be evaluated in the context of the entire enterprise and that the diversification of Cascadia's revenue base dilutes the materiality of any adverse development affecting a single concession.

C. Assessment of the Regulatory-Change Carve-Out (Key Battleground Issue)

The regulatory-change carve-out is, in our assessment, the most significant and most contested analytical issue in the MAE analysis. Its applicability turns on several interrelated questions that are not fully resolvable on the present record.

The Timing Question. As noted above, Oregon SB 1567 was enacted and took effect before the EPA execution date. Under a plain reading of the carve-out's temporal limitation ("occurring after the date of this Agreement"), the statute does not qualify as a post-signing change in law. This interpretation favors the buyer's position and, if adopted, would effectively neutralize the sellers' regulatory-change defense.

However, the sellers' counter-interpretation — that the carve-out's "arising from or relating to" language sweeps in the downstream effects of SB 1567 regardless of the statute's enactment date — has some textual plausibility and cannot be dismissed. Under this reading, the relevant question is not when the statute was enacted but whether the adverse effect is causally connected to a change in law, broadly construed. This interpretation would expand the carve-out's reach to encompass effects flowing from any regulatory change, regardless of timing, so long as the change is the proximate or contributing cause of the adverse effect.

We believe the stronger textual argument favors the buyer's position. The temporal limitation is explicit and unambiguous: the carve-out applies to changes "occurring after the date of this Agreement." This limitation would be rendered largely meaningless if the carve-out were read to encompass effects arising from pre-EPA regulatory changes that simply manifest post-signing. A Delaware court applying standard principles of contract interpretation would likely give effect to the temporal limitation and hold that SB 1567, as a pre-existing regulatory condition, is not a "change" occurring after the EPA date.

The Contractual vs. Regulatory Characterization. As discussed in Section III.B.1, the proximate cause of the adverse effect is the Water District's exercise of a contractual renegotiation right under Section 14 of the Bull Run Concession Agreement. Even if SB 1567 is the underlying regulatory trigger, the mechanism through which the adverse effect operates is contractual, not regulatory. The regulatory-change carve-out, properly construed, addresses effects arising directly from changes in law — not effects arising from contractual counterparty actions that happen to be triggered by regulatory changes.

This distinction is analytically important and, in our assessment, provides an independent basis for concluding that the carve-out does not apply. The Water District's renegotiation notice is a counterparty action under a commercial contract. The fact that the Water District is a municipal body does not transform its contractual actions into regulatory actions for purposes of the MAE definition. The EPA's carve-out for "acts of government" requires general applicability, which the renegotiation notice — specific to the Bull Run Concession — plainly lacks.

Disclosure Considerations. The sellers' argument may be further weakened by disclosure considerations. The EPA's representations and disclosure schedules were prepared with knowledge of SB 1567's existence and its potential impact on Cascadia's concession portfolio. If the sellers did not disclose the risk of renegotiation in the disclosure schedules — or if the disclosure was incomplete or misleading — the sellers may face additional exposure under the EPA's representation-and-warranty framework, independent of the MAE analysis. We have requested the relevant disclosure schedules from Meridian's counsel and will provide an updated analysis once they are received and reviewed.

The Concession Agreement's Renegotiation Provisions. We have not yet obtained a complete copy of the Bull Run Concession Agreement and cannot fully evaluate the scope and terms of the Section 14 renegotiation right. The terms of the renegotiation provision — including the triggers, scope, procedural requirements, and remedies — will be important to the analysis. If the renegotiation right is broadly drafted and gives the Water District significant leverage to modify the concession terms, the potential adverse impact on Cascadia is greater, strengthening the case for an MAE. Conversely, if the renegotiation right is narrowly circumscribed, the risk of a materially adverse outcome may be more limited.

VI. Impact on Closing Conditions

A. No-MAE Closing Condition

Section 7.02(a) of the EPA contains a closing condition requiring, as a condition to the Buyer's obligation to consummate the transactions, that "no Material Adverse Effect shall have occurred since the date of this Agreement and be continuing as of the Closing Date." This is the standard "no-MAE" closing condition, also sometimes referred to as the "bring-down" condition with respect to the MAE.

If an MAE has occurred, Cascadia Acquisition Corp. — and by extension, Fund IV and ICM Co-Invest — would not be obligated to consummate the closing. The failure of the no-MAE closing condition would entitle the Buyer to decline to close without liability (subject to the EPA's termination provisions and any reverse-termination-fee obligations, which are analyzed in a separate memorandum).

However, asserting that the no-MAE closing condition has failed is a high-stakes determination. The Buyer would be required to affirmatively take the position that an MAE has occurred, and the sellers would likely dispute this determination and potentially pursue litigation to compel closing or recover damages. The risk of litigation is significant, particularly given the analytical ambiguities discussed above, and an incorrect MAE assertion could expose the Buyer to claims for breach of contract, specific performance, and/or the reverse-termination fee.

We note that under Delaware law, the burden of proof on an MAE claim rests with the party asserting it — in this case, the Buyer. The Buyer would need to demonstrate by a preponderance of the evidence that the events in question satisfy the MAE definition, taking into account the carve-outs and the disproportionate-impact exception. Given the analytical uncertainties, we believe that an MAE assertion at this time would carry meaningful litigation risk.

B. Representations Bring-Down

Section 7.02(b) of the EPA contains a closing condition requiring that the Selling Shareholders' representations and warranties set forth in Article III of the EPA be true and correct in all material respects (or, with respect to representations qualified by materiality or MAE, in all respects) as of the EPA date and as of the closing date.

The representations likely relevant to the concession renegotiation include:

(a) Section 3.08 — Material Contracts. The EPA likely includes a representation that each material contract listed on the disclosure schedules is in full force and effect, has not been amended or modified except as disclosed, and is not subject to any pending or threatened termination, renegotiation, or material modification. If the Bull Run Concession Agreement is listed as a material contract (as it almost certainly is), the renegotiation may affect the accuracy of this representation.

(b) Section 3.10 — Compliance with Laws. The EPA likely includes a representation that Cascadia is in compliance with all applicable laws, including Oregon SB 1567. If SB 1567 imposes compliance obligations that Cascadia has not yet met, this representation may be implicated.

(c) Section 3.12 — Absence of Certain Changes. The EPA may include a representation that, since a specified date, there has been no material adverse change in the business, financial condition, or results of operations of Cascadia. If the renegotiation constitutes such a change, this representation may be affected.

We have not reviewed the full text of the applicable representations or the associated disclosure schedules and cannot provide a definitive assessment of whether the representations bring-down condition has failed. We have requested these materials from Meridian's counsel and will update our analysis accordingly.

C. Interaction with EPA Outside Date

The current EPA outside date is December 31, 2022. Given the early stage of the concession renegotiation, it is highly unlikely that the renegotiation will be resolved before this date. The renegotiation process, even if conducted in good faith and with reasonable dispatch, is likely to extend over a period of months and potentially longer.

This timing creates practical pressure to extend the outside date. As noted above, a proposed First Amendment to the EPA extending the outside date to March 31, 2023, is under active consideration. Our analysis of the First Amendment, including its implications for the no-MAE closing condition, the representations bring-down, and Ironside's rights and remedies, is set forth in a separate memorandum dated November 20, 2022.

We note that an extension of the outside date does not, by itself, constitute a waiver of the no-MAE closing condition or any other closing condition. The no-MAE condition continues to apply throughout the extended period, and the MAE analysis remains relevant — indeed, becomes more relevant — as additional time passes and the renegotiation progresses. However, Ironside should ensure that any agreement to extend the outside date expressly preserves all of the Buyer's rights under the EPA, including the right to assert an MAE, and does not contain language that could be construed as a waiver or limitation of those rights.

VII. Implications for ICM Cascadia Co-Invest, LP

A. Ironside's Position as Limited Partner

Ironside Capital Management LP holds a 99.99% limited-partnership interest in ICM Cascadia Co-Invest, LP, reflecting a capital commitment of $299,970,000 (with the remaining $30,000 attributable to the general partner's interest). The general partner of ICM Co-Invest is Meridian Infrastructure GP IV LLC (the "GP"), an affiliate of Meridian Infrastructure Partners LP.

Under the LP Agreement and the Side Letter between Ironside and the GP, both dated July 29, 2022, the GP has exclusive authority over investment decisions of the vehicle, including the determination of whether to close th

I. Executive Summary
This memorandum addresses a significant development in the pending acquisition of Cascadia Renewables Holdings, Inc. ("Cascadia" or the "Company") by Cascadia Acquisition Corp. (the "Buyer"), a special-purpose entity jointly controlled by Meridian Infrastructure Partners LP ("Meridian" or "Fund IV") and ICM Cascadia Co-Invest, LP ("ICM Co-Invest"), of which Ironside Capital Management LP ("Ironside" or "ICM") is the 99.99% limited partner.
On October 28, 2022, the Portland Metropolitan Water District (the "Water District") notified Cascadia that it intended to exercise its contractual right to renegotiate the 40-year water-treatment concession for the Bull Run Filtration Project (the "Bull Run Concession"), originally executed in 2018. The Water District's stated basis for the renegotiation notice is changed regulatory requirements under Oregon Senate Bill 1567 ("Oregon SB 1567" or "SB 1567"), a state law enacted during the 2022 legislative session imposing new treatment standards, monitoring obligations, and reporting requirements on water-treatment facilities operating under long-term concession or public-private-partnership arrangements.
On November 10, 2022, Meridian Infrastructure Partners LP, through its outside counsel, Breckenridge Sloane & Pratt LLP (Charles A. Delacroix, partner), notified Ironside of this development, characterizing it as a material development potentially affecting the Cascadia acquisition and Ironside's co-investment commitment.
This memorandum analyzes whether the concession renegotiation constitutes a "Material Adverse Effect" ("MAE") as defined in Article I of the Equity Purchase Agreement (the "EPA") dated September 15, 2022, among the Selling Shareholders (Timberline Growth Equity Fund III, LP, the Weir Family Trust, and the Management Rollover Pool), Cascadia Renewables Holdings, Inc., and Cascadia Acquisition Corp. Specifically, we examine the operative MAE definition, the enumerated carve-outs, the quantitative and qualitative dimensions of the concession renegotiation, and the implications for the closing conditions, Ironside's co-investment position, and the representations and warranty insurance policy.
Summary Conclusion. The concession renegotiation presents a strong factual basis for asserting that an MAE has occurred or is reasonably likely to occur. The Bull Run Concession generates approximately $64 million in annual revenue, representing approximately 13.1% of Cascadia's FY 2021 total revenue of $487 million, and an estimated $18–22 million in annual EBITDA contribution, representing approximately 13–16% of total FY 2021 EBITDA of $138 million. The long-duration nature of the concession (approximately 36 years remaining) amplifies the significance of any adverse modification to its economic terms.
However, the analysis is materially complicated by several carve-outs in the EPA's MAE definition. The regulatory-change carve-out and the industry-wide-effects carve-out are the most significant analytical obstacles to an MAE assertion. The applicability of these carve-outs turns on factual and interpretive questions that are not fully resolvable on the present record, including (a) whether Oregon SB 1567 constitutes a "change in law" occurring after the EPA execution date (given that SB 1567 was enacted and took effect before September 15, 2022), (b) whether the Water District's renegotiation notice is properly characterized as a regulatory action or a contractual counterparty action, and (c) whether SB 1567's effects are industry-wide or disproportionately affect Cascadia relative to other similarly situated water-treatment concession holders.
Additionally, the renegotiation is in its earliest stages and may result in modified — rather than terminated — concession terms. Delaware courts have historically set a high bar for MAE findings, requiring evidence of a material adverse impact on the target's earnings potential measured over a commercially reasonable period, and have been reluctant to find an MAE based on ongoing developments whose ultimate impact remains uncertain.
Recommendation. We recommend that Ironside preserve its rights to assert an MAE but refrain from doing so at this time. Ironside should instruct Calderwood & Harkness LLP ("C&H") to deliver a formal reservation-of-rights letter to Meridian's counsel and should request regular updates on the renegotiation's progress. The MAE analysis should be reassessed as new facts emerge, including any proposed renegotiated terms, changes in the scope of the renegotiation, or indications of the Water District's ultimate position. This reassessment should occur, at minimum, at each decision point concerning the extension of the EPA's outside date.
II. Factual Background
A. The Bull Run Filtration Project Concession
Cascadia Renewables Holdings, Inc. holds a 40-year water-treatment concession with the Portland Metropolitan Water District for the Bull Run Filtration Project, a large-scale water-treatment and filtration facility serving portions of the Portland metropolitan area's municipal water supply. The concession was originally executed in approximately 2018, following a competitive procurement process conducted by the Water District. Under the terms of the concession agreement, Cascadia is responsible for the design, construction, financing, operation, and maintenance of the Bull Run Filtration Project in exchange for availability-based payments and volume-based fees from the Water District over the 40-year concession term.
Annual revenue generated under the Bull Run Concession is approximately $64 million. This figure is based on FY 2021 audited financial data and reflects a combination of fixed availability payments and variable throughput-based fees. The concession payment structure is subject to annual escalation provisions tied to a blended index of the Consumer Price Index and a construction-cost index, providing a degree of inflation protection that has been a key feature of the concession's economic profile.
The Bull Run Concession is one of three water-treatment concessions operated by Cascadia across the Pacific Northwest. The other two are (i) a 30-year concession with the Spokane Regional Water Authority in Washington State, generating approximately $28 million in annual revenue, and (ii) a 25-year concession with the Boise Municipal Water Board in Idaho, generating approximately $19 million in annual revenue. Collectively, Cascadia's water-treatment concession portfolio represents approximately $111 million in annual revenue. The Bull Run Concession is the largest of these three contracts by a significant margin, accounting for approximately 58% of water-treatment concession revenue and approximately 13.1% of total Cascadia revenue.
Cascadia's total FY 2021 revenue, as reported in the audited financial statements prepared by Halstead & Greer LLP, was $487 million. FY 2021 EBITDA was $138 million, reflecting an overall EBITDA margin of approximately 28.3%. Cascadia's operations span 14 hydroelectric facilities, 6 wind farms, and 3 water-treatment concessions across Oregon, Washington, Idaho, and Montana. The Company's business model is centered on long-duration infrastructure concessions and power-purchase agreements, and the investment thesis supporting the agreed enterprise value of $1.95 billion relies substantially on the stability, predictability, and long weighted-average remaining contract life of these revenue streams.
Assuming that the Bull Run Concession generates EBITDA at margins comparable to Cascadia's overall average, the concession's estimated annual EBITDA contribution is in the range of $18–22 million, representing approximately 13–16% of total FY 2021 EBITDA. We note that the actual EBITDA margin on the Bull Run Concession may differ from the overall average due to the capital-intensive nature of the facility and the specific cost structure associated with water-treatment operations; however, in the absence of segment-level margin data (which has not been disclosed to Ironside at this time), the blended-margin assumption provides a reasonable approximation.
The Bull Run Concession is among Cascadia's longest-duration contracts. With approximately 36 years remaining on the concession term as of the date of this memorandum, the Bull Run Concession contributes significantly to the portfolio-wide weighted-average remaining contract life of approximately 22 years, which is a critical metric for infrastructure investors and a key driver of the valuation multiple applied to Cascadia's earnings in the transaction.
B. The Renegotiation Notice
On October 28, 2022, the Portland Metropolitan Water District issued a formal written notice to Cascadia of its intent to renegotiate the terms of the Bull Run Concession (the "Renegotiation Notice"). The notice was addressed to Cascadia's Chief Executive Officer and General Counsel and was delivered by both certified mail and electronic transmission.
The stated basis for the Renegotiation Notice is changed regulatory requirements under Oregon SB 1567, a state law enacted during the 2022 legislative session. Oregon SB 1567, which took effect on July 1, 2022, imposes new standards for water-treatment facilities operating under long-term concession or public-private-partnership arrangements, including enhanced treatment standards, expanded monitoring and reporting requirements, mandatory capital-improvement plans to meet updated environmental and public-health benchmarks, and new community-engagement and transparency obligations. The Water District's notice cites Section 14 of the Bull Run Concession Agreement, which provides a renegotiation right in the event of "material changes in applicable law that substantially alter the regulatory environment governing the Facility's operations or the District's obligations to the public."
Renegotiation was formally opened in November 2022, following the delivery of the notice. As of the date of this memorandum, no resolution or preliminary framework for renegotiated terms has been proposed by either party. The scope of the renegotiation is not fully defined in the notice, and the Water District has indicated only that it intends to address, among other things, compliance with the new regulatory standards, allocation of capital-expenditure obligations associated with facility upgrades, potential modifications to the pricing structure to reflect changed cost burdens, and possible adjustments to performance standards and default provisions. The renegotiation could encompass pricing terms, performance standards, capital-expenditure obligations, term adjustments, or a combination thereof, and the range of potential outcomes is correspondingly broad.
We have not been provided with a copy of the underlying Bull Run Concession Agreement and are relying on the description of its terms as set forth in the EPA disclosure schedules, the Renegotiation Notice (a copy of which was provided to Ironside by Meridian's counsel on November 10, 2022), and discussions with Ironside's internal team. We have requested a complete copy of the concession agreement from Meridian's counsel, and this request is pending as of the date of this memorandum. Access to the full concession agreement is important for several aspects of our analysis, including the scope and triggers of the renegotiation right, the availability of dispute-resolution mechanisms, and the interplay between the concession agreement's force majeure and regulatory-change provisions and the EPA's MAE definition.
C. Transaction Context
The Cascadia acquisition is structured as a 100% equity acquisition. Under the EPA, Cascadia Acquisition Corp., a Delaware corporation organized solely for the purpose of the acquisition and wholly owned by Fund IV and ICM Co-Invest, will acquire all of the outstanding equity interests of Cascadia from the Selling Shareholders. The Selling Shareholders consist of Timberline Growth Equity Fund III, LP (holding approximately 72% of Cascadia's equity), the Weir Family Trust (holding approximately 18%), and the Management Rollover Pool (holding approximately 10%, a portion of which will be rolled over into equity in the post-closing entity).
The agreed enterprise value of Cascadia under the EPA is $1,950,000,000. This implies an EV/EBITDA multiple of approximately 14.1x based on FY 2021 EBITDA of $138 million, as reflected in the audited financial statements prepared by Halstead & Greer LLP. The 14.1x multiple reflects a premium to the broader water and renewable-energy infrastructure sector, attributable principally to the length and quality of Cascadia's contracted revenue streams, the inflation-linked escalation provisions embedded in the Company's concession and power-purchase agreements, and the favorable regulatory environment in the Pacific Northwest.
Total equity committed to the acquisition is $1,050,000,000, structured as follows:
•  Meridian Infrastructure Partners Fund IV, LP: $750,000,000 (71.43% of total equity)
•  ICM Cascadia Co-Invest, LP: $300,000,000 (28.57% of total equity)
The acquisition is financed in part with third-party debt. The senior secured credit facility consists of a $975 million senior secured term loan, arranged by Atlas National Bank, N.A., which serves as the lead arranger and administrative agent (holding a $650 million commitment), and Pinnacle Credit Partners LLC (holding a $325 million commitment). In addition, a $150 million revolving credit facility has been committed by Atlas National Bank (fully undrawn as of the date of this memorandum). The debt commitment letter was executed on August 22, 2022, and the funding of the term loan is subject to customary conditions precedent, including the absence of a material adverse effect as defined in the credit agreement (which contains its own MAE definition, analyzed in a separate C&H memorandum dated August 30, 2022).
The EPA was executed on September 15, 2022. The original outside date — the date by which the closing must occur, failing which either party may terminate the EPA — is December 31, 2022. We understand from discussions with Ironside and with Meridian's counsel that an extension of the outside date to March 31, 2023, is under active consideration and is the subject of a proposed First Amendment to the EPA. The First Amendment is analyzed in a separate C&H memorandum dated November 20, 2022.
ICM Cascadia Co-Invest, LP has issued a single capital call dated August 15, 2022, in the amount of $22,500,000, representing 7.5% of Ironside's total commitment of $300,000,000 (Ironside's 99.99% LP share being $299,970,000, with the remaining $30,000 attributable to Meridian Infrastructure GP IV LLC's general-partner interest). The unfunded commitment of $277,500,000 remains subject to future capital calls in accordance with the terms of the Limited Partnership Agreement of ICM Cascadia Co-Invest, LP (the "LP Agreement") dated July 29, 2022.
III. Material Adverse Effect Definition Under the EPA
A. Text of the MAE Definition
The operative MAE definition is set forth in Section 1.01 of the EPA, within the defined terms of Article I. As is standard in negotiated acquisition agreements of this nature, the MAE definition consists of two principal components: (i) an affirmative definition of what constitutes an MAE, and (ii) a series of enumerated carve-outs specifying categories of events, changes, or effects that are excluded from the definition regardless of their adverse impact.
The affirmative definition follows the standard formulation prevalent in Delaware-law-governed acquisition agreements. Specifically, Section 1.01 of the EPA defines a "Material Adverse Effect" as:
"any event, change, effect, development, condition, or occurrence that, individually or in the aggregate with all other events, changes, effects, developments, conditions, or occurrences, has had or would reasonably be expected to have a material adverse effect on (a) the business, assets, liabilities, financial condition, or results of operations of the Company and its Subsidiaries, taken as a whole, or (b) the ability of the Selling Shareholders or the Company to consummate the transactions contemplated by this Agreement."
Several features of this definition warrant particular attention in the context of the present analysis.
First, the definition encompasses not only effects that "have had" a material adverse impact but also those that "would reasonably be expected to have" such an impact. This forward-looking element is critical in the concession-renegotiation context because the renegotiation has not yet produced any definitive economic impact — no renegotiated terms have been proposed or agreed. The question is whether the initiation of the renegotiation process, and the attendant risk of materially adverse renegotiated terms, is sufficient to satisfy the "reasonably expected" standard.
Second, the definition applies to effects considered "individually or in the aggregate." This aggregation principle means that the concession renegotiation need not independently satisfy the materiality threshold; it may be combined with other adverse developments affecting Cascadia to reach the MAE standard. We are not aware of other material adverse developments at this time, but we note this provision for completeness.
Third, the qualifier "taken as a whole" requires that the effect be material to the entire Cascadia enterprise, not merely to a single contract or business line. This is a significant analytical consideration because Cascadia is a diversified infrastructure platform operating 14 hydroelectric facilities, 6 wind farms, and 3 water-treatment concessions. An adverse development affecting one concession, even one as significant as the Bull Run Concession, must be evaluated in the context of the enterprise as a whole.
Fourth, the definition includes a second limb — clause (b) — addressing effects on the ability of the Selling Shareholders or the Company to consummate the transactions. This limb is less likely to be directly implicated by the concession renegotiation (which does not, on its face, affect the parties' ability to close), but it could become relevant if the renegotiation affects the lenders' willingness to fund under the debt commitment letter, thereby indirectly impeding closing.
B. Enumerated Carve-Outs
The MAE definition contains six enumerated carve-outs, each specifying a category of event, change, or effect that is excluded from the MAE definition. We analyze each carve-out below in the context of the concession renegotiation.
1. Regulatory/Legislative Change Carve-Out
The first carve-out excludes from the MAE definition:
any effect arising from or relating to changes in applicable law, rules, regulations, orders, or other binding directives issued by any governmental authority, or changes in the interpretation or enforcement thereof, in each case occurring after the date of this Agreement.
This carve-out is directly relevant to the concession renegotiation and is likely to be the central battleground in any dispute over whether an MAE has occurred.
The threshold question is whether Oregon SB 1567 constitutes a "change in applicable law" occurring "after the date of this Agreement." The EPA was executed on September 15, 2022. Oregon SB 1567 was enacted during the 2022 legislative session and took effect on July 1, 2022 — more than two months before the EPA execution date. On its face, SB 1567 appears to be a pre-existing regulatory condition at the time the EPA was signed, not a post-signing "change" in applicable law.
However, the analysis is not straightforward. Several sub-issues warrant detailed examination.
Timing of the Change in Law. The text of the carve-out limits its application to changes "occurring after the date of this Agreement." The enactment and effective date of Oregon SB 1567 both precede the EPA date. Under a plain-reading approach, the statute does not qualify as a change in law occurring after September 15, 2022, and the carve-out would not apply to shield the renegotiation from the MAE definition.
Downstream Effects of a Pre-EPA Regulatory Change. The sellers are likely to argue that even though SB 1567 itself predates the EPA, the effects of the statute — including the Water District's exercise of its contractual renegotiation right — are properly characterized as effects "arising from or relating to" a change in law. Under this reading, the carve-out would be triggered not by the timing of the statute's enactment but by the causal connection between the regulatory change and the adverse effect on Cascadia. This argument has some textual support in the "arising from or relating to" language, which is broad and potentially encompasses downstream consequences of a statutory change even if the statute itself predates the agreement.
Counterargument: Pre-Existing Conditions and the Signing-Date Baseline. Under standard MAE analysis, the date of the agreement establishes the baseline against which materiality is measured. Pre-existing conditions — including laws already enacted and in effect — are part of the baseline. Changes in the target's business that flow from pre-existing conditions generally are not shielded by the regulatory-change carve-out because the carve-out is designed to protect sellers from the risk of post-signing regulatory developments, not from the realization of risks that existed at the time of signing. Under this reasoning, SB 1567 was a known regulatory condition at the time the EPA was executed, and its effects — including the possibility that the Water District would exercise its renegotiation right — were part of the landscape against which the parties struck their bargain. The sellers (and their counsel at Morgan Cross & Whitfield LLP) would have been aware of SB 1567 at the time the EPA was negotiated and executed, and the failure to disclose or address the renegotiation risk in the EPA may itself be significant.
The Renegotiation Right as Contractual, Not Regulatory. An additional analytical layer concerns the characterization of the Water District's action. The Renegotiation Notice invokes Section 14 of the Bull Run Concession Agreement — a contractual provision permitting renegotiation upon specified regulatory changes. The Water District is not exercising a legislative or regulatory power; it is exercising a contractual right under a pre-existing concession agreement. If the renegotiation right is properly characterized as a contractual action by a counterparty rather than a change in law per se, the regulatory-change carve-out may not apply even if SB 1567 is treated as the underlying cause.
This distinction — between the regulatory trigger and the contractual mechanism through which the adverse effect operates — is analytically significant. The carve-out addresses changes in "applicable law"; it does not expressly address contractual actions taken in response to changes in law. Courts interpreting similar carve-outs have generally focused on the proximate cause of the adverse effect rather than its ultimate or root cause. Under this approach, the proximate cause of the adverse effect on Cascadia is the Water District's exercise of its contractual renegotiation right, not the enactment of SB 1567, and the carve-out should not apply.
Disproportionate Impact Exception. The regulatory-change carve-out contains a standard proviso excepting from the carve-out any effect that "disproportionately affects the Company and its Subsidiaries, taken as a whole, relative to other participants in the industries in which the Company and its Subsidiaries operate." This exception is discussed in detail in Section III.C below.
2. Industry-Wide Effects Carve-Out
The second carve-out excludes from the MAE definition:
any effect generally affecting the industries or markets in which the Company and its Subsidiaries operate, including changes in prevailing interest rates, commodity prices, or market valuations.
This carve-out is relevant to the extent that Oregon SB 1567 affects the water-infrastructure concession industry broadly rather than Cascadia specifically. If the statute imposes new requirements on all water-treatment concession holders in Oregon, and if renegotiation notices have been issued (or are reasonably expected to be issued) to other concession holders, the adverse effects may be characterized as industry-wide and thus excluded from the MAE definition.
Our analysis of this carve-out requires factual information that is not fully available as of the date of this memorandum. The key factual questions include: How many other water-treatment concession holders operate in Oregon under similar long-term concession or public-private-partnership arrangements? Have other municipal counterparties issued renegotiation notices in response to SB 1567? Is the Bull Run Concession unique in its susceptibility to renegotiation under the statute, or is the renegotiation risk broadly shared across the Oregon water-infrastructure concession market?
If SB 1567 affects the industry broadly and other concession holders face comparable renegotiation risks, the industry-wide-effects carve-out would shelter the sellers, subject to the disproportionate-impact exception. If, conversely, the Bull Run Concession is uniquely affected — for example, because of the specific terms of its concession agreement, the particular regulatory requirements applicable to the Bull Run Filtration Project, or the Water District's unique position among Oregon municipal water authorities — the industry-wide carve-out may not apply.
We recommend that Ironside request from Meridian detailed factual information regarding the impact of SB 1567 on other water-treatment concessions in Oregon, including whether other municipal counterparties have issued renegotiation notices or indicated an intent to do so.
3. General Economic and Market Conditions Carve-Out
The EPA carves out from the MAE definition:
any effect arising from or relating to general economic, political, financial, or market conditions, including changes in prevailing interest rates, currency exchange rates, credit markets, capital markets, or equity markets.
This carve-out is unlikely to be directly applicable to the concession renegotiation, which is driven by a specific regulatory development (Oregon SB 1567) and a specific counterparty action (the Water District's renegotiation notice) rather than by general economic or market conditions. We note this carve-out for completeness but do not consider it a significant analytical factor in the present context.
4. Acts of Government / Regulatory Action Carve-Out
The EPA contains a carve-out for:
any effect arising from or relating to any action taken by any governmental authority, including any legislative, regulatory, or judicial action or any enforcement action, in each case of general applicability.
This carve-out overlaps with and supplements the regulatory-change carve-out discussed in Section III.B.1 above. Its applicability to the concession renegotiation turns on two questions: (a) whether the Portland Metropolitan Water District's renegotiation notice constitutes an "action taken by any governmental authority" and (b) whether the action is "of general applicability."
The Portland Metropolitan Water District occupies a dual role: it is both a municipal governmental body and a contractual counterparty to Cascadia under the Bull Run Concession Agreement. When the Water District issues a renegotiation notice pursuant to a contractual provision in the concession agreement, it is acting in its capacity as a contracting party — not in its regulatory or legislative capacity. The action is specific to the Bull Run Concession Agreement and is directed at Cascadia as the concessionaire, not at the industry at large. Under this characterization, the governmental-action carve-out may not apply because the Water District's action is neither a regulatory action nor an action of general applicability.
However, the sellers may argue that the Water District's action is properly understood as a governmental action because the Water District is a municipal body exercising a right triggered by legislative action (SB 1567), and that the nature of the Water District's action cannot be divorced from its governmental character. This argument is stronger if the Water District's renegotiation right is viewed as an implementing mechanism for SB 1567 rather than an independent contractual action.
The "general applicability" limitation is an additional obstacle for the sellers. Even if the Water District's action is characterized as governmental, it is specific to the Bull Run Concession and is not of general applicability. The carve-out, by its terms, applies only to governmental actions "of general applicability."
5. Pandemic / Force Majeure Carve-Out
The EPA excludes from the MAE definition effects arising from pandemics, epidemics, disease outbreaks, or natural disasters. This carve-out is not applicable to the concession renegotiation and is noted solely for completeness.
6. Transaction-Related Carve-Out
The EPA carves out:
any effect arising from or attributable to the announcement or pendency of the transactions contemplated by this Agreement, including any loss of, or change in the relationship with, any customer, supplier, employee, or business partner resulting therefrom.
This carve-out is designed to insulate sellers from adverse effects caused by the announcement of the acquisition itself — such as customer defections, employee departures, or supplier renegotiations triggered by uncertainty about the target's post-acquisition ownership. The concession renegotiation was triggered by Oregon SB 1567, not by the announcement or pendency of the Cascadia acquisition. There is no factual basis for concluding that the Water District's renegotiation notice was motivated by or related to the acquisition. Accordingly, this carve-out is not directly relevant to the present analysis.
C. Interaction of Carve-Outs with "Disproportionate Impact" Exception
Most of the carve-outs in the MAE definition — including the regulatory-change carve-out, the industry-wide-effects carve-out, and the general-economic-conditions carve-out — contain a proviso commonly known as the "disproportionate impact" exception. The EPA's version of this proviso states:
provided, however, that with respect to clauses (i) through (iv) above, such events, changes, effects, developments, conditions, or occurrences shall be taken into account in determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur to the extent that such events, changes, effects, developments, conditions, or occurrences have a disproportionate adverse effect on the Company and its Subsidiaries, taken as a whole, relative to other participants in the industries in which the Company and its Subsidiaries operate.
The disproportionate-impact exception is the analytical mechanism by which carve-outs that would otherwise shield the sellers can be overridden. Even if the concession renegotiation is caused by a regulatory change (SB 1567) or constitutes an industry-wide effect, the MAE definition is reinstated if the renegotiation disproportionately affects Cascadia relative to other participants in the water-infrastructure concession industry.
The disproportionate-impact analysis requires a factual comparison of Cascadia's situation with that of other similarly situated companies. The relevant comparator group would consist of other companies holding long-term water-treatment concessions in Oregon (and potentially the broader Pacific Northwest). Key factual questions include:
(a) How many other water-treatment concessions in Oregon are subject to SB 1567? Are there other concessions of comparable size and duration?
(b) Have other municipal water authorities issued renegotiation notices to their concessionaires in response to SB 1567? If not, is the Water District's action unique to Cascadia's Bull Run Concession?
(c) Does the Bull Run Concession Agreement contain renegotiation provisions that are more favorable to the Water District than comparable provisions in other concession agreements? Is the contractual trigger for renegotiation in Section 14 of the Bull Run Concession Agreement unusual or industry-standard?
(d) Does Cascadia hold a unique or outsized position in the Oregon water-treatment concession market such that SB 1567's impact falls disproportionately on Cascadia?
If Cascadia is the only concession holder — or one of a very small number — to receive a renegotiation notice, or if the economic impact of the renegotiation is proportionally greater for Cascadia than for other concession holders, the disproportionate-impact exception would apply, and the regulatory-change and industry-wide carve-outs would not shield the sellers.
Conversely, if SB 1567 has triggered renegotiation notices across the industry, and the economic impact on Cascadia is proportionate to the impact on other concession holders, the disproportionate-impact exception would not apply, and the carve-outs would protect the sellers.
We do not have sufficient factual information to resolve this question definitively at this time and recommend that Ironside pursue the factual inquiries outlined above through Meridian and, if necessary, through independent research or consultants familiar with the Oregon water-infrastructure market.
IV. Quantitative Materiality Analysis
A. Revenue Impact
The Bull Run Concession generates approximately $64 million in annual revenue. Cascadia's total FY 2021 revenue, as reflected in the audited financial statements, was $487 million. The Bull Run Concession therefore represents approximately 13.1% of Cascadia's total revenue.
However, the mere existence of the renegotiation does not necessarily mean that the entire $64 million revenue stream is at risk. The range of potential outcomes from the renegotiation spans from modest pricing adjustments to significant term modifications to (at the extreme, and we believe unlikely) termination of the concession. Each of these outcomes carries a different quantitative implication for the MAE analysis.
We have modeled three representative scenarios below:
Scenario 1 — Modest Adjustment. If the renegotiation results in a modest pricing adjustment — for example, a 5–10% reduction in annual concession revenue to reflect the Water District's increased regulatory costs under SB 1567 — the annual revenue impact would be approximately $3.2 million to $6.4 million. This represents approximately 0.7% to 1.3% of total Cascadia revenue. An impact of this magnitude would be unlikely to constitute an MAE on quantitative grounds alone, even taking into account the long-duration nature of the concession (36 years remaining). The net present value of a $3.2–6.4 million annual reduction over 36 years, discounted at a reasonable cost of capital, would represent a meaningful but not necessarily material reduction in enterprise value.
Scenario 2 — Significant Renegotiation. If the renegotiation results in a significant reduction in concession economics — for example, a 25–40% reduction in annual concession revenue, reflecting substantial modifications to pricing terms, additional capital-expenditure obligations, or other economic concessions by Cascadia — the annual revenue impact would be approximately $16 million to $25.6 million. This represents approximately 3.3% to 5.3% of total Cascadia revenue. An impact of this magnitude falls into an analytically ambiguous range. Depending on the durational significance and other qualitative factors, it could support an MAE assertion, but the case would not be clear-cut.
Scenario 3 — Concession Termination or Fundamental Restructuring. In the most adverse scenario — a termination of the concession, a constructive repudiation by the Water District, or a fundamental restructuring of the concession that eliminates the majority of its economic value — the full $64 million annual revenue stream would be at risk. This represents approximately 13.1% of total Cascadia revenue. An impact of this magnitude presents a substantially stronger quantitative case for an MAE, particularly given the long remaining term of the concession and the centrality of the Bull Run Concession to Cascadia's contracted revenue portfolio.
We emphasize that these scenarios are illustrative and that the actual outcome of the renegotiation remains highly uncertain at this early stage.
B. EBITDA Impact
Translating the revenue-impact analysis into EBITDA terms, and assuming that the Bull Run Concession operates at margins comparable to Cascadia's overall average EBITDA margin of approximately 28.3% ($138 million EBITDA on $487 million revenue), the estimated EBITDA contribution of the Bull Run Concession is approximately $18–22 million per year. We present a range rather than a point estimate because we do not have segment-level financial data for the Bull Run Concession and recognize that the actual margin may differ from the blended corporate average.
The impact on implied enterprise value, at the agreed 14.1x EV/EBITDA multiple, is significant:
Under a full-loss scenario, the implied reduction in enterprise value of $254–310 million represents a substantial impairment — roughly 13% to 16% of the agreed enterprise value of $1.95 billion. Under a significant-renegotiation scenario, the implied reduction of $63–124 million, while meaningful, represents a smaller percentage of enterprise value and may not meet the quantitative threshold for an MAE under prevailing Delaware precedent.
C. Case Law and Precedent on Quantitative Thresholds
Delaware courts have not established a bright-line quantitative threshold for MAE determinations, but the case law provides useful guidance on the range of quantitative impacts that have been found sufficient — or insufficient — to constitute an MAE.
The Delaware Court of Chancery's decision in Akorn, Inc. v. Fresenius Kabi AG (2018) remains the leading authority on MAE analysis. In Akorn, the court found an MAE based on, among other factors, a sustained decline in earnings of approximately 50–60%, combined with evidence that the decline was durable and resulted from systematic regulatory compliance failures rather than temporary market conditions. The Akorn court emphasized that an MAE requires a significant adverse impact on the target's earnings potential measured over a "commercially reasonable period," which the court characterized as a period of years rather than months.
Prior Delaware decisions — including the Court of Chancery's earlier opinions in IBP, Inc. v. Tyson Foods (2001) and Hexion Specialty Chemicals, Inc. v. Huntsman Corp. (2008) — similarly set a high bar for MAE findings. In IBP, the court declined to find an MAE based on a 64% decline in quarterly earnings, characterizing the decline as a short-term fluctuation inconsistent with the durational expectations inherent in the MAE standard. In Hexion, the court's analysis focused on the long-term impact of the alleged adverse developments on the target's business prospects, again emphasizing that temporary or cyclical downturns do not constitute MAEs.
The general framework that emerges from the Delaware case law can be summarized as follows:
(a) Impacts of approximately 40% or more of earnings, sustained over a commercially reasonable period, are generally regarded as sufficient to constitute an MAE.
(b) Impacts in the range of 10–20% of earnings fall into an analytically ambiguous "gray zone" in which the MAE determination depends heavily on the durational significance, the qualitative nature of the adverse development, and the overall context.
(c) Impacts below approximately 10% of earnings are generally regarded as insufficient to constitute an MAE in the absence of extraordinary qualitative circumstances.
The 13.1% revenue-at-risk figure (and the corresponding 13–16% EBITDA-at-risk estimate) places this situation squarely in the gray zone under prevailing Delaware precedent if the full concession revenue is lost. Scenarios involving partial renegotiation — particularly the modest-adjustment scenario — are likely to fall below the quantitative threshold. Scenarios involving significant renegotiation are analytically uncertain and would require strong qualitative arguments (including durational significance and centrality to the investment thesis) to support an MAE determination.
D. Durational Significance
The Bull Run Concession is a 40-year contract with approximately 36 years remaining as of the date of this memorandum. Any material modification to the concession's economic terms would have implications extending over decades — well beyond the "commercially reasonable period" contemplated by the Delaware courts' durational-significance standard. This factor strongly favors an MAE finding in the event of a materially adverse renegotiation outcome.
The long-duration nature of the concession means that even a relatively modest annual revenue reduction, compounded over the remaining 36-year term, produces a large aggregate impact. For example, a 25% reduction in annual concession revenue ($16 million per year) over 36 years represents $576 million in aggregate undiscounted lost revenue and approximately $180–220 million in net-present-value terms at a discount rate of 7–9% — a significant fraction of the agreed enterprise value.
However, we note an important caveat: the renegotiation itself is in its earliest stages. No renegotiated terms have been proposed or agreed, and the ultimate outcome remains highly uncertain. Delaware courts have generally been reluctant to find an MAE based on ongoing developments whose final impact is not yet known. The IBP court emphasized the importance of "known rather than projected circumstances" in the MAE analysis, and the Akorn court required evidence of a "durationally significant" impact before concluding that an MAE had occurred. An ongoing renegotiation, by its nature, does not yet demonstrate the kind of durable, realized impact that Delaware courts have required.
This tension — between the potentially large long-term impact and the present uncertainty about the outcome — is a central challenge in the current MAE analysis and reinforces our recommendation that Ironside preserve its rights but refrain from asserting an MAE at this time.
V. Application of MAE Analysis to the Concession Renegotiation
A. Arguments Supporting an MAE Finding
We identify the following principal arguments supporting the conclusion that the concession renegotiation constitutes an MAE or is reasonably likely to result in one:
1. Magnitude of Revenue at Risk. The Bull Run Concession generates approximately $64 million in annual revenue, representing approximately 13.1% of Cascadia's total FY 2021 revenue. Even under a partial-renegotiation scenario, the revenue at risk is substantial, and the potential EBITDA impact ($18–22 million annually in a full-loss scenario) is meaningful relative to Cascadia's total EBITDA of $138 million. As discussed in Section IV above, the quantitative impact, while not clearly above the threshold established in the Delaware case law, falls within the range that courts have treated as analytically significant.
2. Durational Significance. The concession has approximately 36 years remaining on its term. Any adverse modification to the concession's economics would persist for decades, producing a large cumulative impact. This factor strongly favors an MAE finding under the durational-significance framework established by the Delaware courts.
3. Centrality of Bull Run to the Investment Thesis. The Bull Run Filtration Project is Cascadia's single largest water-treatment concession and one of the crown jewels of the Company's contracted revenue portfolio. The concession was a significant driver of the agreed enterprise value of $1.95 billion and the premium 14.1x EV/EBITDA multiple. The investment thesis supporting Ironside's $300 million co-investment commitment relied, in significant part, on the stability and predictability of the Bull Run revenue stream over the remaining concession term. A material impairment of this revenue stream would fundamentally alter the risk-return profile of the investment.
4. Regulatory-Change Carve-Out May Not Apply. As analyzed in detail in Section III.B.1 above, Oregon SB 1567 was enacted and took effect before the EPA execution date of September 15, 2022. Under a plain-reading approach, SB 1567 does not constitute a change in law occurring "after the date of this Agreement" and is not covered by the regulatory-change carve-out. Moreover, the proximate cause of the adverse effect on Cascadia is the Water District's exercise of a contractual renegotiation right under the Bull Run Concession Agreement — a counterparty action, not a change in law.
5. Disproportionate Impact Argument. If the Bull Run Concession is uniquely affected by SB 1567 — for example, because the Bull Run Concession Agreement contains broader renegotiation triggers than other Oregon water-treatment concessions, or because the Bull Run Filtration Project faces more extensive compliance requirements under SB 1567 than other facilities — the disproportionate-impact exception to the carve-outs would apply, reinstating the MAE definition. Ironside should pursue the factual inquiries necessary to evaluate this argument.
B. Arguments Against an MAE Finding (Sellers' Likely Position)
We anticipate that the Selling Shareholders, through their counsel at Morgan Cross & Whitfield LLP, would advance the following arguments in response to an MAE assertion:
1. Regulatory-Change Carve-Out. The sellers' strongest argument is that Oregon SB 1567 constitutes a change in applicable law and that the concession renegotiation flows directly from that regulatory change. Sellers will argue that the carve-out's "arising from or relating to" language is broad enough to encompass the downstream effects of the statute, including the Water District's exercise of a contractual renegotiation right triggered by the regulatory change. They may characterize the Water District's notice as the natural and foreseeable regulatory consequence of SB 1567, rather than an independent contractual action.
2. Industry-Wide Effects. Sellers may argue that SB 1567 affects all water-treatment concession holders in Oregon, making the concession renegotiation an industry-wide effect sheltered by the industry-wide-effects carve-out. If other concession holders are similarly affected, the impact on Cascadia is not unique to the Company but rather a shared condition of the industry.
3. No Disproportionate Impact. Sellers will contend that Cascadia is not disproportionately affected by SB 1567 relative to other similarly situated companies. If other Oregon water-treatment concession holders face comparable renegotiation risks, the disproportionate-impact exception does not apply.
4. Renegotiation Does Not Equal Termination. The sellers will emphasize that the concession has not been terminated, repudiated, or fundamentally impaired. A renegotiation may result in modified terms that preserve significant economic value for Cascadia. The sellers may point to the possibility of favorable renegotiation outcomes — such as a modest pricing adjustment, a term extension, or a rebalancing of capital-expenditure obligations — that would mitigate the economic impact.
5. Prematurity. No renegotiation outcome has been reached. Asserting an MAE at this early stage — before any proposed terms have been put forward — is inherently speculative and premature. Delaware courts have consistently required evidence of a realized or reasonably ascertainable adverse impact, not merely the initiation of a process that may or may not result in adverse outcomes.
6. Quantitative Threshold Not Clearly Met. The sellers will argue that a 13.1% revenue impact (and the corresponding 13–16% EBITDA impact) does not satisfy the high quantitative bar set by Delaware courts for MAE findings. Citing IBP and the pre-Akorn case law, the sellers will contend that impacts below approximately 40% of earnings are presumptively insufficient to constitute an MAE, and that the 13.1% figure falls well below this threshold.
7. "Taken as a Whole" Qualifier. Cascadia is a diversified infrastructure platform with operations spanning hydroelectric, wind, and water-treatment assets across four states. The Bull Run Concession, while significant, is one of 23 operating assets. The sellers will argue that the impact of the renegotiation must be evaluated in the context of the entire enterprise and that the diversification of Cascadia's revenue base dilutes the materiality of any adverse development affecting a single concession.
C. Assessment of the Regulatory-Change Carve-Out (Key Battleground Issue)
The regulatory-change carve-out is, in our assessment, the most significant and most contested analytical issue in the MAE analysis. Its applicability turns on several interrelated questions that are not fully resolvable on the present record.
The Timing Question. As noted above, Oregon SB 1567 was enacted and took effect before the EPA execution date. Under a plain reading of the carve-out's temporal limitation ("occurring after the date of this Agreement"), the statute does not qualify as a post-signing change in law. This interpretation favors the buyer's position and, if adopted, would effectively neutralize the sellers' regulatory-change defense.
However, the sellers' counter-interpretation — that the carve-out's "arising from or relating to" language sweeps in the downstream effects of SB 1567 regardless of the statute's enactment date — has some textual plausibility and cannot be dismissed. Under this reading, the relevant question is not when the statute was enacted but whether the adverse effect is causally connected to a change in law, broadly construed. This interpretation would expand the carve-out's reach to encompass effects flowing from any regulatory change, regardless of timing, so long as the change is the proximate or contributing cause of the adverse effect.
We believe the stronger textual argument favors the buyer's position. The temporal limitation is explicit and unambiguous: the carve-out applies to changes "occurring after the date of this Agreement." This limitation would be rendered largely meaningless if the carve-out were read to encompass effects arising from pre-EPA regulatory changes that simply manifest post-signing. A Delaware court applying standard principles of contract interpretation would likely give effect to the temporal limitation and hold that SB 1567, as a pre-existing regulatory condition, is not a "change" occurring after the EPA date.
The Contractual vs. Regulatory Characterization. As discussed in Section III.B.1, the proximate cause of the adverse effect is the Water District's exercise of a contractual renegotiation right under Section 14 of the Bull Run Concession Agreement. Even if SB 1567 is the underlying regulatory trigger, the mechanism through which the adverse effect operates is contractual, not regulatory. The regulatory-change carve-out, properly construed, addresses effects arising directly from changes in law — not effects arising from contractual counterparty actions that happen to be triggered by regulatory changes.
This distinction is analytically important and, in our assessment, provides an independent basis for concluding that the carve-out does not apply. The Water District's renegotiation notice is a counterparty action under a commercial contract. The fact that the Water District is a municipal body does not transform its contractual actions into regulatory actions for purposes of the MAE definition. The EPA's carve-out for "acts of government" requires general applicability, which the renegotiation notice — specific to the Bull Run Concession — plainly lacks.
Disclosure Considerations. The sellers' argument may be further weakened by disclosure considerations. The EPA's representations and disclosure schedules were prepared with knowledge of SB 1567's existence and its potential impact on Cascadia's concession portfolio. If the sellers did not disclose the risk of renegotiation in the disclosure schedules — or if the disclosure was incomplete or misleading — the sellers may face additional exposure under the EPA's representation-and-warranty framework, independent of the MAE analysis. We have requested the relevant disclosure schedules from Meridian's counsel and will provide an updated analysis once they are received and reviewed.
The Concession Agreement's Renegotiation Provisions. We have not yet obtained a complete copy of the Bull Run Concession Agreement and cannot fully evaluate the scope and terms of the Section 14 renegotiation right. The terms of the renegotiation provision — including the triggers, scope, procedural requirements, and remedies — will be important to the analysis. If the renegotiation right is broadly drafted and gives the Water District significant leverage to modify the concession terms, the potential adverse impact on Cascadia is greater, strengthening the case for an MAE. Conversely, if the renegotiation right is narrowly circumscribed, the risk of a materially adverse outcome may be more limited.
VI. Impact on Closing Conditions
A. No-MAE Closing Condition
Section 7.02(a) of the EPA contains a closing condition requiring, as a condition to the Buyer's obligation to consummate the transactions, that "no Material Adverse Effect shall have occurred since the date of this Agreement and be continuing as of the Closing Date." This is the standard "no-MAE" closing condition, also sometimes referred to as the "bring-down" condition with respect to the MAE.
If an MAE has occurred, Cascadia Acquisition Corp. — and by extension, Fund IV and ICM Co-Invest — would not be obligated to consummate the closing. The failure of the no-MAE closing condition would entitle the Buyer to decline to close without liability (subject to the EPA's termination provisions and any reverse-termination-fee obligations, which are analyzed in a separate memorandum).
However, asserting that the no-MAE closing condition has failed is a high-stakes determination. The Buyer would be required to affirmatively take the position that an MAE has occurred, and the sellers would likely dispute this determination and potentially pursue litigation to compel closing or recover damages. The risk of litigation is significant, particularly given the analytical ambiguities discussed above, and an incorrect MAE assertion could expose the Buyer to claims for breach of contract, specific performance, and/or the reverse-termination fee.
We note that under Delaware law, the burden of proof on an MAE claim rests with the party asserting it — in this case, the Buyer. The Buyer would need to demonstrate by a preponderance of the evidence that the events in question satisfy the MAE definition, taking into account the carve-outs and the disproportionate-impact exception. Given the analytical uncertainties, we believe that an MAE assertion at this time would carry meaningful litigation risk.
B. Representations Bring-Down
Section 7.02(b) of the EPA contains a closing condition requiring that the Selling Shareholders' representations and warranties set forth in Article III of the EPA be true and correct in all material respects (or, with respect to representations qualified by materiality or MAE, in all respects) as of the EPA date and as of the closing date.
The representations likely relevant to the concession renegotiation include:
(a) Section 3.08 — Material Contracts. The EPA likely includes a representation that each material contract listed on the disclosure schedules is in full force and effect, has not been amended or modified except as disclosed, and is not subject to any pending or threatened termination, renegotiation, or material modification. If the Bull Run Concession Agreement is listed as a material contract (as it almost certainly is), the renegotiation may affect the accuracy of this representation.
(b) Section 3.10 — Compliance with Laws. The EPA likely includes a representation that Cascadia is in compliance with all applicable laws, including Oregon SB 1567. If SB 1567 imposes compliance obligations that Cascadia has not yet met, this representation may be implicated.
(c) Section 3.12 — Absence of Certain Changes. The EPA may include a representation that, since a specified date, there has been no material adverse change in the business, financial condition, or results of operations of Cascadia. If the renegotiation constitutes such a change, this representation may be affected.
We have not reviewed the full text of the applicable representations or the associated disclosure schedules and cannot provide a definitive assessment of whether the representations bring-down condition has failed. We have requested these materials from Meridian's counsel and will update our analysis accordingly.
C. Interaction with EPA Outside Date
The current EPA outside date is December 31, 2022. Given the early stage of the concession renegotiation, it is highly unlikely that the renegotiation will be resolved before this date. The renegotiation process, even if conducted in good faith and with reasonable dispatch, is likely to extend over a period of months and potentially longer.
This timing creates practical pressure to extend the outside date. As noted above, a proposed First Amendment to the EPA extending the outside date to March 31, 2023, is under active consideration. Our analysis of the First Amendment, including its implications for the no-MAE closing condition, the representations bring-down, and Ironside's rights and remedies, is set forth in a separate memorandum dated November 20, 2022.
We note that an extension of the outside date does not, by itself, constitute a waiver of the no-MAE closing condition or any other closing condition. The no-MAE condition continues to apply throughout the extended period, and the MAE analysis remains relevant — indeed, becomes more relevant — as additional time passes and the renegotiation progresses. However, Ironside should ensure that any agreement to extend the outside date expressly preserves all of the Buyer's rights under the EPA, including the right to assert an MAE, and does not contain language that could be construed as a waiver or limitation of those rights.
