report include, but are not limited to, statements about our expectations, objectives, anticipations, plans, hopes, beliefs, intentions or

strategies regarding the future.

Words such as “expects,” “anticipates,” “aims,” “projects,” “intends,” “plans,” “believes,” “estimates,” “seeks,” “continue,” “could,”

“may,” “potential,” “should,” “will,” “would,” variations of such words and similar expressions are also intended to identify such forward-looking

statements. These forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict; therefore,

actual results may differ materially and adversely from those expressed in any forward-looking statement. Readers are directed to risks and

uncertainties identified under Part II, Item 1A, “Risk Factors,” and elsewhere in this report for factors that may cause actual results to be

different from those expressed in these forward-looking statements. Except as required by law, we undertake no obligation to revise or

update publicly any forward-looking statement for any reason.

decision to enter into an acquisition and/or fund investments in our latest technology arising from rapid market adoption that

could require us to seek additional equity or debt financing;

• our expectations relating to the amount and timing of recognized revenue from our projects;

• our expectations relating to expenses;

• our expectation that we will continue to receive a tax benefit related to U.S. federal foreign-derived intangible income and

Basis of Presentation

The Condensed Consolidated Financial Statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries.

All intercompany accounts and transactions have been eliminated in consolidation.

The accompanying Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the

Securities and Exchange Commission (the “ SEC ”). Certain information and footnote disclosures normally included in the financial statements

prepared in accordance with U.S. generally accepted accounting principles (“ GAAP ”) have been condensed or omitted pursuant to such rules

and regulations. The December 31, 2023 Condensed Consolidated Balance Sheet was derived from audited financial statements and may

not include all disclosures required by GAAP; however, the Company believes that the disclosures are adequate to make the information

presented not misleading.

The September 30, 2024 unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited

Consolidated Financial Statements and the notes thereto for the fiscal year ended December 31, 2023 included in the Company’s Annual

Report on Form 10-K filed with the SEC on February 21, 2024 (the “ 2023 Annual Report ”).

The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any

future periods .

Reclassifications

Certain prior period amounts have been reclassified in certain notes to the Condensed Consolidated Financial Statements to conform

to the current period presentation.

Use of Estimates

The preparation of Condensed Consolidated Financial Statements, in conformity with GAAP , requires the Company’s management to

make judgments, assumptions and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and

accompanying notes.

The accounting policies that reflect the Company’s significant estimates and judgments and that the Company believes are the most

critical to aid in fully understanding and evaluating its reported financial results are revenue recognition; granted equity award valuations;

equipment useful life and valuation; goodwill valuation and impairment; deferred taxes and valuation allowances on deferred tax assets; and

evaluation and measurement of contingencies . Those estimates could change, and as a result, actual results could differ materially from

those estimates.

The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a

revision of the carrying value of its assets or liabilities as of October 30, 2024 , the date of issuance of this Quarterly Report on Form 10-Q .

These estimates may change, as new events occur and additional information is obtained. Actual results could differ materially from these

estimates under different assumptions or conditions. The Company undertakes no obligation to publicly update these estimates for any

reason after the date of this Quarterly Report on Form 10-Q , except as required by law.

Significant Accounting Policies

There have been no material changes to the Company’s significant accounting policies in Note 1, “ Description of Business and

Significant Accounting Policies - Significant Accounting Policies ,” of the Notes to Consolidated Financial Statements included in Item 8,

“Financial Statements and Supplementary Data,” of the 2023 Annual Report .

Recently Issued Accounting Pronouncement Not Yet Adopted

There have been no issued accounting pronouncements that have not yet been adopted during the nine months ended

September 30, 2024 that apply to the Company other than the pronouncements disclosed in Note 1, “ Description of Business and Significant

Accounting Policies - Recently Issued Accounting Pronouncement Not Yet Adopted ,” of the Notes to Consolidated Financial Statements

included in Item 8, “Financial Statements and Supplementary Data,” of the 2023 Annual Report .

Note 3 — Net Income (Loss) Per Share

Net income (loss) for the reported period is divided by the weighted average number of basic and diluted common shares outstanding

during the reported period to calculate the basic and diluted net income (loss) per share , respectively. Outstanding stock options to purchase

common shares and unvested restricted stock units (“RSUs”) are collectively referred to as “equity awards.”

• Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the

period .

• Diluted net income (loss) per share is computed using the weighted average number of common and potentially dilutive shares

outstanding during the period, using the treasury stock method. Any anti-dilutive effect of equity awards outstanding is not

included in the computation of diluted net income (loss) per share .

The following tables present the computation of basic and diluted net income (loss) per share .

Goodwill

Goodwill is tested for impairment annually in the third quarter of the Company’s fiscal year or more frequently if indicators of potential

impairment exist. The Company monitors the industries in which it operates and reviews its business performance for indicators of potential

impairment. The recoverability of goodwill is measured at the reporting unit level, which represents the operating segment. The carrying

amount of goodwill as of September 30, 2024 and December 31, 2023 was $ 12.8 million .

On July 1, 2024 , the Company estimated the fair value of its reporting units using the discounted cash flow approach and market

approach. The forecast of future cash flows, which is based on the Company’s best estimate of future net sales and operating expenses, is

based primarily on expected category expansion, pricing, market segment, and general economic conditions . The Company incorporates

other significant inputs to its fair value calculations, including discount rate and market multiples, to reflect current market conditions. As a

result, the analysis performed indicated that the fair value of each reporting unit, that is allocated goodwill, significantly exceeds its carrying

value, and therefore, no impairment charges were recorded.

Litigation

From time-to-time, the Company has been named in and subject to various proceedings and claims in connection with its business.

The Company may in the future become involved in litigation in the ordinary course of business, including litigation that could be material to

its business. The Company considers all claims, if any, on a quarterly basis and, based on known facts, assesses whether potential losses

are considered reasonably possible, probable and estimable. Based upon this assessment, the Company then evaluates disclosure

requirements and whether to accrue for such claims in its consolidated financial statements. The Company records a provision for a liability

when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are

reviewed at least quarterly and are adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other

information and events pertaining to a particular case. As of September 30, 2024 , the Company was not involved in any lawsuits, legal

proceedings or claims that would have a material effect on the Company’s financial position, results of operations, or cash flows. Therefore,

there were no material losses which were probable or reasonably possible.

Effective tax rate	3.9 %	5.1 %	62.4 %	( 114.2 %)
Effective tax rate, excluding discrete items	8.7 %	8.6 %	11.8 %	10.0 %

The Company’s interim period tax provision for (benefit from) income taxes is determined using an estimate of its annual effective tax

rate, adjusted for discrete items, if any, that arise during the period . Each quarter, the Company update s its estimate of the annual effective

tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period . The

Company’s quarterly tax provision and estimate of its annual effective tax rate are subject to variation due to several factors, including

variability in accurately predicting its pre-tax income or loss and the mix of jurisdictions to which they relate, the applicability of special tax

regimes, and changes in how the Company does business .

For the three and nine months ended September 30, 2024 , the recognized provision for and (benefit from) income taxes, respectively,

resulted from the tax projection based on the full year forecasted profit and included benefits related to the U.S. federal foreign-derived

intangible income (“FDII”), federal research and development (“ R&D ”) tax credit , certain permanent differences, such as share-based

compensation shortfalls, and partial release of California valuation allowance .

For the three and nine months ended September 30, 2023, the recognized provision for and (benefit from) income taxes, respectively,

included benefits related to the U.S. FDII and federal R&D tax credit, along with a discrete tax benefit due primarily to share-based

compensation windfalls and prior years’ discrete tax benefit largely related to increased tax credits.

The effective tax rate excluding discrete items for the nine months ended September 30, 2024 , as compared to the prior year, differed

primarily due to lower projected R&D tax credits, increased non-deductible officer share-based compensation, and lower projected U.S. FDII

benefits .

Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of

Operations

Overview

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our” and “us”) designs and manufactures solutions that make

industrial processes more efficient and sustainable. Leveraging our pressure exchanger technology, which generates little to no emissions

when operating , we believe our solutions lower costs, save energy, reduce waste, and minimize emissions for companies across a variety of

commercial and industrial processes . As the world coalesces around the urgent need to address climate change and its impacts, we are

helping companies reduce their energy consumption in their industrial processes, which in turn, reduces their carbon footprint. We believe

that our customers do not have to sacrifice quality and cost savings for sustainability and we are committed to developing solutions that drive

long-term value – both financial and environmental .

The original product application of our technology, the PX ® Pressure Exchanger ® (“ PX ”) energy recovery device , was a major

contributor to the advancement of seawater reverse osmosis desalination (“ SWRO ”), significantly lowering the energy intensity and cost of

water production globally from SWRO . Our pressure exchanger technology is being applied to the wastewater filtration market, such as

battery manufacturers, mining operations, municipalities, and other manufacturing plants that discharge wastewater with significant levels of

metals and pollutants, and has also been applied to the development of our PX G1300 ® for use in the CO 2 market.

Engineering, and research and development (“ R&D ”), have been, and remain, an essential part of our history , culture and corporate

strategy. Since our formation, we have developed leading technology and engineering expertise through the continual evolution of our

pressure exchanger technology, which can enhance environmental sustainability and improve productivity by reducing waste and energy

consumption in high-pressure industrial fluid-flow systems. This versatile technology works as a platform to build product applications and is

at the heart of many of our products. In addition, we have engineered and developed ancillary devices, such as our hydraulic turbochargers

and circulation “booster” pumps, that complement our energy recovery device s.

Segments

Our reportable operating segments consist of the water and emerging technologies segments. These segments are based on the

industries in which the technology solutions are sold, the type of energy recovery device or other technology sold and the related solution and

service or, in the case of emerging technologies, where revenues from new and/or potential devices utilizing our pressure exchanger

technology can be brought to market. Other factors for determining the reportable operating segments include the manner in which our Chief

Operating Decision Maker (“CODM”), our President and Chief Executive Officer , evaluates our performance combined with the nature of the

individual business activities. In addition, our corporate operating expenses include expenditures in support of the water and emerging

technologies segments. We continue to monitor and review our segment reporting structure in accordance with authoritative guidance to

determine whether any changes have occurred that would impact our reportable segments .

Results of Operations

A discussion regarding our financial condition and results of operations for the three and nine months ended September 30, 2024 ,

compared to the three and nine months ended September 30, 2023 , is presented below.

Revenue

Variability in revenue from quarter to quarter is typical, therefore year-on-year comparisons are not necessarily indicative of the trend

for the full year due to these variations. There is no specific seasonality in our revenues to highlight that occurs throughout a calendar year.

We generally track our revenues by channels. The channels we recognize and channel definitions we utilize are as follows:

• Megaproject (“ MPD ”) channel: The MPD channel has been the main driver of our long-term growth as revenue from this channel

benefits from a growing number of projects as well as an increase in the capacity of these projects in some cases. MPD projects

are large-scale in nature and generally have shipment timelines from 16 to 36 months from contract date. Recognition of

revenue is dependent on customers’ project timing and execution of these projects.

• Original Equipment Manufacturer (“ OEM ”) channel: The OEM channel reflects sales to a wide variety of industries in the

desalination, wastewater, and the refrigeration markets. This channel contains projects smaller in size and revenue, and of

shorter duration compared to those projects in the MPD channel.

• Aftermarket (“ AM ”) channel: The AM channel represents support and services rendered to our installed customer base. AM

revenue generally fluctuates from year-to-year and is dependent on our customers’ timing of product upgrades, as well as their

replenishment of spare parts and supplies .

Three months ended September 30, 2024 , as compared to the three months ended September 30, 2023

The increase in MPD revenue of $2.2 million was due primarily to:

• Desalination: The decrease in revenue of $0.6 million was due primarily to lower shipments of products to the Americas and

Middle East and Africa (“MEA”) markets, partially offset by higher shipments of products to the Asia and Europe markets.

• Wastewater: The increase in revenue of $2.8 million was due primarily to higher shipments of products to the MEA market.

The decrease in OEM revenue of $0.4 million was due primarily to :

• Desalination: The decrease in revenue of $0.6 million was due primarily to lower shipments of products to the Asia and Americas

markets, partially offset by higher shipments of products to the MEA and Europe markets.

• Wastewater: The increase in revenue of $0.3 million was due primarily to higher shipments of products to the Asia market,

partially offset by lower shipments of products to the Europe and Americas markets.

• Emerging Technology : The decrease in revenue of $0.1 million was due primarily to lower shipments of products.

The decrease in AM revenue of $0.2 million was due primarily to lower shipments of products to the Asia market, partially offset by

higher shipments of products to the Europe and MEA markets.

Nine months ended September 30, 2024 , as compared to the nine months ended September 30, 2023

The increase in MPD revenue of $6.6 million was due primarily to:

• Desalination: The increase in revenue of $3.8 million was due primarily to higher shipments of products to the MEA, Asia and

Europe markets, partially offset by lower shipments of products to the Americas market.

• Wastewater: The increase in revenue of $2.8 million was due primarily to higher shipments of products to the MEA market.

The decrease in OEM revenue of $1.6 million was primarily due to :

• Desalination: The decrease in revenue of $0.5 million was due primarily to lower shipments of products to the Asia and Americas

markets, partially offset by higher shipments of products to the MEA and Europe markets.

• Wastewater: The decrease in revenue of $0.9 million was due primarily to lower shipments of products in all markets, with the

largest decrease in the Europe market.

• Emerging Technology : The decrease in revenue of $0.3 million was due primarily to an installment in Europe and sales to a gas

producer in the Americas, both occurring in the prior year.

The increase in AM revenue of $1.7 million was due primarily to higher shipments of product to the A mericas, Asia, and the MEA

markets, partially offset by lower shipments of product to the Asia market .

Concentration of Revenue

See Note 10 , “ Concentrations , ” of the Notes to Condensed Consolidated Financial Statements in Part I, Item 1, “Financial Statements

(unaudited),” of this Quarterly Report on Form 10-Q (the “ Notes ”) for further discussion regarding our concentration of revenue.

Gross Profit and Gross Margin

Gross profit represents revenue less cost of revenue. Cost of revenue consists primarily of raw materials, personnel costs (including

share-based compensation), manufacturing overhead, warranty costs, and depreciation expense.


	Three Months Ended September 30,				Nine Months Ended September 30,
	2024	2023	Change		2024	2023	Change

Gross margin	65.1%	69.9%	(480) bps	(100.0) %	64.0 %	66.9 %	(290) bps

The decrease in gross profit for the three months ended September 30, 2024 , as compared to the prior year, was due primarily to a

decrease in gross margin, partially offset by an increase in sales of PXs. The decrease in gross margin for the three months ended

September 30, 2024 , as compared to the prior year, was due primarily to higher manufacturing costs, higher costs related to product mix , and

an increase in freight costs and indirect costs .

The increase in gross profit for the nine months ended September 30, 2024 , as compared to the prior year, was due primarily to an

increase in sales of PXs, partially offset by a decrease in gross margin. The decrease in gross margin for the nine months ended

September 30, 2024 , as compared to the prior year, was due primarily to higher manufacturing costs and freight costs, partially offset by

average selling prices related to product mix.

Effective tax rate	3.9%	5.1%	62.4%	(114.2%)
Effective tax rate, excluding discrete items	8.7%	8.6%	11.8%	10.0%

The interim period tax provision for (benefit from) income taxes is determined using an estimate of our annual effective tax rate,

adjusted for discrete items, if any, that arise during the period . Each quarter, we update our estimate of the annual effective tax rate, and if

the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. The quarterly tax provision and estimate

of our annual effective tax rate are subject to variation due to several factors, including variability in accurately predicting our pre-tax income

or loss and the mix of jurisdictions to which they relate, the applicability of special tax regimes, and changes in how we do business .

For the three and nine months ended September 30, 2024 , the recognized provision for and (benefit from) income taxes, respectively,

resulted from the tax projection based on the full year forecasted profit and included benefits related to the U.S. federal foreign-derived

intangible income (“FDII”), federal R&D tax credit , certain permanent differences, such as share-based compensation shortfalls, and partial

release of California valuation allowance .

For the three and nine months ended September 30, 2023, the recognized provision for and (benefit from) income taxes, respectively,

included benefits related to the U.S. FDII and federal R&D tax credit, along with a discrete tax benefit due primarily to share-based

compensation windfalls and prior years’ discrete tax benefit largely related to increased tax credits.

The effective tax rate excluding discrete items for the nine months ended September 30, 2024 , as compared to the prior year, differed

primarily due to lower projected R&D tax credits, increased non-deductible officer share-based compensation, and lower projected U.S. FDII

benefits.

Liquidity and Capital Resources

Overview

From time-to-time, management and our Board of Directors review our liquidity and future cash needs and may make a decision to

(1) return capital to our shareholders through a share repurchase program or dividend payout; or (2) seek additional debt or equity financing.

As of September 30, 2024 , our principal sources of liquidity consisted of (i) unrestricted cash and cash equivalents of $63.3 million that are

primarily invested in money market funds and U.S. treasury securities ; (ii) investment-grade short-term and long-term marketable debt

instruments of $76.7 million that are primarily invested in U.S. treasury securities, corporate notes and bonds, and municipal and agency

notes and bonds ; and (iii) accounts receivable, net of allowances, of $31.8 million . As of September 30, 2024 , there was unrestricted cash of

$1.1 million held outside the U.S. We invest cash not needed for current operations predominantly in investment-grade, marketable debt

instruments with the intent to make such funds available for future operating purposes, as needed. Although these securities are available for

sale, we generally hold these securities to maturity, and therefore, do not currently see a need to trade these securities in order to support our

liquidity needs in the foreseeable future. We believe the risk of this portfolio to us is in the ability of the underlying companies or government

agencies to cover their obligations at maturity, not in our ability to trade these securities at a profit. Based on current projections, we believe

existing cash balances and future cash inflows from this portfolio will meet our liquidity needs for at least the next 12 months.

Credit Agreement

We entered into a credit agreement with JPMorgan Chase Bank, N.A. (“ JPMC ”) on December 22, 2021 (as amended, the “ Credit

Agreement ”). The Credit Agreement , which will expire on December 21, 2026 , provides a committed revolving credit line of $50.0 million and

includes both a revolving loan and a letters of credit (“ LCs ”) component. The maximum allowable LCs under the credit line component of the

Credit Agreement is $30.0 million . As of September 30, 2024 , we were in compliance with all covenants under the Credit Agreement .

Under the Credit Agreement , as of September 30, 2024 , there were no revolving loans outstanding. In addition, as of September 30,

2024 , under the LCs component, we utilized $18.4 million of the maximum allowable credit line of $30.0 million , which included newly

issued LCs, and previously issued and unexpired stand-by letters of credits (“SBLCs”) and certain non-expired commitments under the

previous Loan and Pledge Agreement with Citibank, N.A., which are guaranteed under the Credit Agreement . As of September 30, 2024 ,

there was $17.4 million of outstanding LCs. These LCs had a weighted average remaining life of approximately 17 months .

See Note 6 , “ Lines of Credit ,” of the Notes for further discussion related to the Credit Agreement .

Net change in cash, cash equivalents and restricted cash	$ (4,832)	$ (4,892)	$ 60

Cash Flows from Operating Activities

Net cash provided by operating activities is subject to the project driven, non-cyclical nature of our business. Operating cash flow can

fluctuate significantly from year to year, due to the timing of receipts of large project orders. Operating cash flow may be negative in one year

and significantly positive in the next, consequently individual quarterly results and comparisons may not necessarily indicate a significant

trend, either positive or negative.

The lower net cash provided by operating assets and liabilities for the nine months ended September 30, 2024 , as compared to the

prior year, was due primarily to the following factors :

• Accounts receivable and contract assets: an increase in cash provided primarily related to an increase in revenues, the timing of

billings related to shipments of product or certification of installations, and collections on the account receivable balances;

• Inventory : an increase in cash used primarily related to the increase in PXs manufactured for project deliveries in the fourth

quarter of 2024 and early 2025; and

• Accrued liabilities : an increase in cash used primarily related to a decreas e in employee compensation and benefits, and a

reduction of tax accruals.

Cash Flows from Investing Activities

Net cash used in investing activities primarily relates to sales, maturities and purchases of investment-grade marketable debt

instruments, such as corporate notes and bonds, and capital expenditures supporting our growth. We believe our investments in marketable

debt instruments are structured to preserve principal and liquidity while at the same time maximizing yields without significantly increasing

risk. The higher net cash used in investing activities of $3.8 million in the nine months ended September 30, 2024 , as compared to the prior

year, was primarily driven by $3.8 million of net cash used for purchases of marketable debt instruments.

Cash Flows from Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2024 , as compared to the cash provided by

financing activities in the prior year, was due primarily to an increase of cash from exercises of employee stock options granted under our

equity incentive plans.

Liquidity and Capital Resource Requirements

We believe that our existing resources and cash generated from our operations will be sufficient to meet our anticipated capital

requirements for at least the next 12 months. However, we may need to raise additional capital or incur additional indebtedness to continue

to fund our operations or to support acquisitions in the future and/or to fund investments in our latest technology arising from rapid market

adoption. These needs could require us to seek additional equity or debt financing. Our future capital requirements will depend on many

factors including the continuing market acceptance of our products, our rate of revenue growth, the timing of new product introductions, the

expansion of our R&D, manufacturing and S&M activities, and the timing and extent of our expansion into new geographic territories. In

addition, we may enter into potential material investments in, or acquisitions of, complementary businesses, services or technologies in the

future which could also require us to seek additional equity or debt financing. Should we need additional liquidity or capital funds, these funds

may not be available to us on favorable terms, or at all.

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk may be found primarily in two areas, foreign currency and interest rates.

Foreign Currency Risk

Our foreign currency exposures are due to fluctuations in exchange rates for the U.S. dollar (“USD”) versus the British pound, Saudi

riyal, Emirati dirham, European euro, Chinese yuan, Indian rupee and Canadian dollar. Changes in currency exchange rates could adversely

affect our consolidated operating results or financial position.

Our revenue contracts have been denominated in the USD. At times, our international customers may have difficulty in obtaining

the USD to pay our receivables, thus increasing collection risk and potential bad debt expense. To the extent we expand our international

sales, a larger portion of our revenue could be denominated in foreign currencies. As a result, our cash and operating results could be

increasingly affected by changes in exchange rates.

In addition, we pay many vendors in foreign currency and, therefore, are subject to changes in foreign currency exchange rates. Our

international sales and service operations incur expense that is denominated in foreign currencies. This expense could be materially affected

by currency fluctuations. Our international sales and services operations also maintain cash balances denominated in foreign currencies. To

decrease the inherent risk associated with translation of foreign cash balances into our reporting currency, we do not maintain excess cash

balances in foreign currencies.

We have not hedged our exposure to changes in foreign currency exchange rates because expenses in foreign currencies have been

insignificant to date and exchange rate fluctuations have had little impact on our operating results and cash flows. In addition, we do not

have any exposure to the Russian ruble.

Interest Rate and Credit Risks

The primary objective of our investment activities is to preserve principal and liquidity while at the same time maximizing yields without

significantly increasing risk. We invest primarily in investment-grade short-term and long-term marketable debt instruments that are subject

to counter-party credit risk. To minimize this risk, we invest pursuant to an investment policy approved by our Board of Directors. The policy

mandates high credit rating requirements and restricts our exposure to any single corporate issuer by imposing concentration limits.

As of September 30, 2024 , our investment portfolio of $88.1 million , in investment-grade marketable debt instruments, such as U.S.

treasury securities, corporate notes and bonds, and municipal and agency notes and bonds , are classified as either cash equivalents or

short-term and/or long-term investments on our Condensed Consolidated Balance Sheets. These investments are subject to interest rate

fluctuations and decrease in market value to the extent interest rates increase, which occurred during the nine months ended September 30,

2024 . To minimize the exposure due to adverse shifts in interest rates, we maintain investments with a weighted average maturity of

approximately eight months . As of September 30, 2024 , a hypothetical 1% increase in interest rates would have resulted in a less than

$0.4 million decrease in the fair value of our investments in marketable debt instruments as of such date.
