NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The unaudited condensed consolidated financial statements of Digi International Inc. ("we", "us", "our", "Digi" or "the Company") have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission applicable to interim financial statements. While these financial statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. These financial statements should be read in conjunction with the financial statement disclosures in our Annual Report on Form 10-K for the year ended September 30, 2020 (the "2020 Financial Statements"). We use the same accounting policies in preparing quarterly and annual financial statements. The quarterly results of operations are not necessarily indicative of the results to be expected for the full year.

As described in Note 9, effective with the reorganization announcement on October 7, 2020, the measure of segment operating income (loss) used by our chief operating decision maker ("CODM") changed. As a result, our disclosed measure of segment operating income (loss) has been updated.

Potential Impacts of COVID-19 on our Business

The impact of the coronavirus ("COVID-19") pandemic continues to unfold. The extent of the pandemic's effect on our operational and financial performance will depend in large part on future developments, which cannot be reasonably estimated at this time. Future developments include the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact both within and outside the jurisdictions where we operate, the impact on governmental programs and budgets, the development of treatments or vaccines, and the timing and level of resumption of widespread economic activity. Due to the inherent uncertainty of the unprecedented and rapidly evolving situation, we are unable to predict with any confidence the likely impact of the COVID-19 pandemic on our future operations. For a more detailed discussion see Part I, Item 1 in our Annual Report on Form 10-K for the year ended September 30, 2020 and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Item 2 of this Form 10-Q.

Recently Issued Accounting Pronouncements

Adopted

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820).  The updated guidance changes the disclosure requirements on fair value measurements. We adopted this standard in the first quarter of fiscal 2021. This standard did not have a material impact on our consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about expected credit losses. We adopted this standard in the first quarter of fiscal 2021, following the modified-retrospective approach. This standard did not have a material impact on our consolidated financial statements.

2. ACQUISITIONS

Acquisition of Haxiot, Inc.

On March 26, 2021, we acquired Haxiot, Inc. ("Haxiot"), a Dallas-based provider of low power wide area ("LPWA") wireless technology. The results of operations are now included in our third quarter of fiscal 2021 results within our IoT Products & Services segment.

The terms of the acquisition included an upfront cash payment as well as contingent consideration comprised of future earn-out payments. We funded the closing of the acquisition with $7.1 million of cash on hand. The future earn-out payments are based on Haxiot revenue performance and contractually are not to exceed $3.0 million and $5.0 million for the annual periods ending December 31, 2021 and December 31, 2022. The fair value amount of these earn-outs for the annual periods ending December 31, 2021 and December 31, 2022 are $3.0 million and $2.9 million, respectively. In the fiscal third quarter of fiscal 2021, the preliminary purchase price allocation was updated, including related determination of fair value and income tax implications. As a result, we adjusted goodwill to $8.6 million and adjusted contingent consideration to $5.9 million on our balance sheet at June 30, 2021.

For tax purposes, this acquisition is treated as a stock acquisition. The goodwill therefore is not deductible. We believe this is a complementary acquisition for us as it significantly enhances our IoT Products & Services segment by enhancing Digi's embedded systems portfolio and immediately extends the company's market reach with a complete LoRaWAN®-based solutions offering.

Costs directly related to the acquisition of $0.2 million incurred fiscal year to date 2021 have been charged to operations and are included in general and administrative expense in our condensed statements of operations. These acquisition costs include legal, accounting, valuation and investment banking fees.

The following table summarizes the preliminary fair values of Haxiot assets acquired and liabilities assumed as of the acquisition date (in thousands).

Cash	$	7,146
Contingent consideration	5,900
Total	$	13,046
Fair value of net tangible assets acquired	$	124
Identifiable intangible assets:
Customer relationships	3,900
Purchased and core technology	1,050
Trademarks	500
Deferred tax liability on identifiable intangible assets	(1,145)
Goodwill	8,617
Total	$	13,046

Acquisition of Opengear, Inc.

On December 13, 2019, we completed our acquisition of Opengear, Inc. ("Opengear"), a New Jersey-based provider of secure IT infrastructure products and software. Opengear results have been included in our condensed consolidated financial statements within our IoT Products & Services segment since the date of acquisition.

During the first quarter of fiscal 2021, we recorded an out-of-period adjustment in connection with the purchase price accounting of Opengear. This balance sheet adjustment resulted in a decrease in fair value of net tangible assets acquired of $1.1 million, a decrease of $0.3 million to non-current deferred tax liability and an increase to goodwill of $0.8 million. Management assessed the impact of this adjustment and believes, after considering both quantitative and qualitative factors, that it is not material to our current or previously issued consolidated financial statements.

The following table summarizes the final fair values of Opengear assets acquired and liabilities assumed as of the acquisition date (in thousands):

8

Cash	$	148,058
Contingent consideration	5,100
Total	$	153,158
Fair value of net tangible assets acquired	$	18,096
Identifiable intangible assets:
Customer relationships	79,000
Purchased and core technology	18,100
Trademarks	8,000
Deferred tax liability on identifiable intangible assets	(27,126)
Goodwill	57,088
Total	$	153,158

The condensed consolidated balance sheet as of June 30, 2021 reflects the final allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition.

3. EARNINGS PER SHARE

The following table is a reconciliation of the numerators and denominators in the net income per common share calculations (in thousands, except per common share data):

	Three months ended June 30,				Nine months ended June 30,
	2021		2020		2021		2020
Numerator:
Net income	$	3,157	$	1,766	$	5,778	$	3,978
Denominator:
Denominator for basic net income per common share — weighted average shares outstanding	34,057		28,972		31,443		28,772
Effect of dilutive securities:
Stock options and restricted stock units	1,091		215		1,263		705
Denominator for diluted net income per common share — adjusted weighted average shares	35,148		29,187		32,706		29,477
Net income per common share, basic	$	0.09	$	0.06	$	0.18	$	0.14
Net income per common share, diluted	$	0.09	$	0.06	$	0.18	$	0.13

For the three months ended June 30, 2021 and 2020, there were 41,540 and 2,241,860 potentially dilutive shares, respectively. For the nine months ended June 30, 2021 and 2020, there were 37,248 and 1,146,581 potentially dilutive shares, respectively. These potentially dilutive shares were related to stock options to purchase common shares that were not included in the above computation of diluted earnings per common share since the options' exercise prices were greater than the average market price of our common shares.

5. FAIR VALUE MEASUREMENTS

Financial assets and liabilities are classified in the following fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1 (unadjusted quoted prices in active markets for identical assets or liabilities); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data).

In connection with our acquisition of Bluenica Corporation ("Bluenica") in October 2015, we agreed to make contingent earn-out payments over a period of up to 4 years, subject to achieving specified revenue thresholds for sales of Bluenica products. We paid the final installment of $2.9 million during the third quarter of fiscal 2020.

In connection with our acquisition of Accelerated Concepts, Inc. ("Accelerated") in January 2018, we agreed to make contingent earn-out payments if specified revenue thresholds for sales of Accelerated products were achieved. We paid the first installment payment of $3.5 million in the third quarter of fiscal 2019. We paid the final installment of $2.4 million in the third quarter of fiscal 2020. The earn-out period for this acquisition ended on January 22, 2020.

In connection with our acquisition of Opengear, we agreed to make contingent payments, based upon certain revenue thresholds (see Note 2 to the condensed consolidated financial statements). We paid the first installment of $0.9 million during the third quarter of fiscal 2020. We paid the final installment of $10.0 million during the second quarter of fiscal 2021.

In connection with our acquisition of Haxiot, we agreed to make contingent earn-out payments, based upon certain revenue thresholds (see Note 2 to the condensed consolidated financial statements). In the fiscal third quarter of fiscal 2021, the preliminary purchase price allocation was updated, including related determination of fair value and income tax implications. As a result, we adjusted goodwill to $8.6 million and adjusted contingent consideration to $5.9 million on our balance sheet at June 30, 2021.

The following table presents a reconciliation of the contingent consideration liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in thousands):

	Three months ended June 30,					Nine months ended June 30,
	2021			2020		2021		2020
Fair value at beginning of period	$	8,000		$	10,379	$	4,228	$	5,407
Contingent consideration recognized for acquired business	—			—		8,000		5,100
Contingent consideration payments	—			(6,151)		(10,000)		(6,151)
Change in fair value of contingent consideration *	(2,100)		*	—		3,672		(128)
Fair value at end of period	$	5,900		$	4,228	$	5,900	$	4,228

* The change in fair value for the three months ended June 30, 2021, totaling ($2,100) represents an adjustment to our preliminary purchase price of Haxiot that does not impact our condensed consolidated statement of operations.

The change in fair value of contingent consideration reflects our estimates of the probabilities of achieving the relevant targets and is discounted based on our estimated discount rate. Due to the timing of the acquisition, the fair value of the contingent consideration at June 30, 2021 is based on the probability of achieving the specified revenue thresholds for Haxiot.

Goodwill represents the excess of cost over the fair value of net identifiable assets acquired. Goodwill is quantitatively tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. We continue to have 2 reportable segments, our IoT Products & Services segment and our IoT Solutions segment (see Note 9). Effective with the reorganization announcement on October 7, 2020 (see Note 14), our IoT Products & Services business is now structured to include four reporting units under the IoT Products & Services segment, each with a reporting manager: Cellular Routers, Console Servers, OEM Solutions and Infrastructure Management. We have four reporting units along with our IoT Solutions segment that have been tested individually for impairment.

Due to the reorganization on October 7, 2020 (see Note 14), we performed our fiscal third quarter 2021 annual impairment test by reporting unit. As a result, we tested Cellular Routers, Console Servers, OEM Solutions, Infrastructure Management and IOT Solutions units which constitute separate reporting units for purposes of the ASC 350-20-35 "Goodwill Measurement of Impairment" assessment, which were tested individually for impairment in fiscal third quarter 2021.

12

For our quantitative goodwill impairment tests, we determine the estimated fair value of each reporting unit and compare it to the carrying value of the reporting unit, including goodwill. If the carrying amount of a reporting unit is higher than its estimated fair value, then an impairment loss must be recognized for the excess. Fair values for the five reporting units were each estimated on a standalone basis using a weighted combination of the income approach and market approach.

6. GOODWILL AND OTHER INTANGIBLE ASSETS, NET (CONTINUED)

The income approach indicates the fair value of a business based on the value of the cash flows the business or asset can be expected to generate in the future. A commonly used variation of the income approach used to value a business is the discounted cash flow (“DCF”) method. The DCF method is a valuation technique in which the value of a business is estimated on the earnings capacity, or available cash flow, of that business. Earnings capacity represents the earnings available for distribution to stockholders after consideration of the reinvestment required for future growth. Significant judgment is required to estimate the amount and timing of future cash flows for each reporting unit and the relative risk of achieving those cash flows.

The market approach indicates the fair value of a business or asset based on a comparison of the business or asset to comparable publicly traded companies or assets and transactions in its industry as well as our prior acquisitions. This approach can be estimated through the guideline company method. This method indicates fair value of a business by comparing it to publicly traded companies in similar lines of business. After identifying and selecting the guideline companies, we make judgments about the comparability of the companies based on size, growth rates, profitability, risk, and return on investment in order to estimate market multiples. These multiples are then applied to the reporting units to estimate a fair value.

Assumptions and estimates to determine fair values under the income and market approaches are complex and often subjective.  They can be affected by a variety of factors. These include external factors such as industry and economic trends. They also include internal factors such as changes in our business strategy and our internal forecasts. Changes in circumstances or a potential event could negatively affect the estimated fair values. We will continue to monitor potential COVID-19 industry and demand impacts as this could potentially affect our cash flows and market capitalization. If our future operating results do not meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicative of a reduction in fair value of one or more of our reporting units, we may be required to record future impairment charges for goodwill.

Results of our Fiscal 2021 Annual Impairment Test

As of June 30, 2021, we had a total of $32.7 million of goodwill for the Enterprise Routers reporting unit, $60.2 million of goodwill for the Console Servers reporting unit, $63.4 million of goodwill for the OEM Solutions reporting unit, $15.4 million of goodwill for the Infrastructure Mgmt. reporting unit and $49.5 million of goodwill for the IoT Solutions reporting unit. At June 30, 2021, fair value exceeded the carrying value by more than 20% for all five reporting units. Implied fair values for both reporting units were each calculated on a standalone basis using a weighted combination of the income approach and market approach. The implied fair values of each reporting unit were added together along with our unallocated assets to get an indicated value of total equity to which a range of indicated value of total equity was derived. This range was compared to the total market capitalization of $686.3 million as of June 30, 2021. This implied a range of control (deficit)/ premiums of (4.5)% to 5.4%. This range of control premiums fell below the control premiums observed in the last five years in the communications equipment industry. As a result, the market capitalization reconciliation analysis proved support for the reasonableness of the fair values estimated for each individual reporting unit.

7. INDEBTEDNESS

On March 15, 2021, we entered into an amended and restated credit agreement with BMO Harris Bank N.A. ("BMO"). This agreement provides us with a senior secured credit facility (the "Credit Facility") consisting of a $200 million revolving loan (the "Revolving Loan"). This loan replaced our syndicated senior secured credit agreement with BMO that was entered into on December 13, 2019 and replaced the remaining balance of our term loan with this new revolver. This prior agreement provided us with committed credit facilities ("Prior Credit Facility") totaling $150 million, which included a $50 million term loan and a $100 million revolving loan. We may use the Revolving Loan for working capital, capital expenditures, restricted payments and acquisitions permitted under the agreement.

13

Borrowings under the Credit Facility bear a variable interest rate of LIBOR plus an applicable margin spread from 1.25% to 3.25%. The amount of the applicable margin spread is a function of our leverage ratio and is reset monthly. In addition to paying interest on the outstanding balance under the Credit Facility, we are required to pay a commitment fee on the non-utilized commitments thereunder which is also reported in interest expense. Our weighted average interest rate at June 30, 2021 was 0.47%.

The additional debt issuance costs and remaining balance under the Prior Credit Facility totaled $2.6 million and is being amortized using the straight-line method over the term of the loan and reported in interest expense.

The Revolving Loan is due in a lump sum payment at maturity on March 15, 2026. The fair value of the Revolving Loan approximated carrying value at June 30, 2021.

7. INDEBTEDNESS (CONTINUED)

The following table is a summary of our long-term indebtedness at June 30, 2021 (in thousands):

Revolving loan	$	48,118
Total loans	48,118
Less unamortized issuance costs	(2,448)
Less current maturities of long-term debt	—
Total long-term debt, net of current portion	$	45,670

Covenants and Security Interest

The agreements governing the Credit Facility contain a number of covenants. Among other thing, these covenants require us to maintain a certain financial ratio (net leverage ratio and minimum fixed charge ratio). At June 30, 2021, we were in compliance with our debt covenants. Amounts borrowed under the Credit Facility are secured by substantially all of our assets.

8. STOCKHOLDERS' EQUITY

Public Offering of Common Stock

During March 2021 we sold 4,025,000 shares of our common stock at a public offering price of $19.50 per share. The shares offered were registered pursuant to a registration statement that we filed with the Securities and Exchange Commission. We received net proceeds of $73.8 million, net of transaction expenses of $0.3 million related to the public offering. We intend to use the proceeds for working capital and general corporate purposes. We may, in the future, use the proceeds to acquire or invest in complementary businesses, products and technologies.

9. SEGMENT INFORMATION

We have two reportable segments: IoT Products & Services and IoT Solutions. Effective with the reorganization announcement on October 7, 2020 (see Note 14), our IoT Products & Services business is now structured to include four operating segments, each with a segment manager. These four operating segments include:

•Cellular Routers - box devices (fully enclosed) that provide connectivity typically in a place where the device can be plugged in exclusively using cellular communications.

•Console Servers - similar to cellular routers except they are exclusively for edge computing installations and data center applications exclusively using cellular communications.

•OEM Solutions - Original Equipment Manufacturers ("OEM") will be a chip, rather than a boxed device. This can come in the form of a stand-alone chip, or from a systems-on-module ("SOMs"). While cellular connectivity is used, other communication protocols can be used such as Zigbee, Bluetooth or Radio-Frequency ("RF") based on application.

•Infrastructure Management - includes battery operated, cellular enabled connect sensors as well as other types of console server applications that are more Digi Accelerated Linux ("DAL") based than Console Servers. This operating segment has some products that do not use cellular communications, but a large part of this segment does use cellular communications.

15

9. SEGMENT INFORMATION (CONTINUED)

The four operating segments have similar qualitative and quantitative factors which allow us to aggregate them under the IoT Products & Services reportable segment. The qualitative factors include similar nature of products and services, production process, type or class of customers and methods used to distribute the products. The quantitative factors include similar operating margins. Our CODM reviews and makes business decisions which includes a primary review of operating income but also includes gross profit. Thus, our measure of segment profit or loss used by our CODM changed. The shared general and administrative costs are now allocated to each operating segment. As a result, our disclosed measure of segment operating income has been updated for all periods presented. The change to the business segment operating income aligns with the update to how the CODM assesses performance and allocates resources for our business segments.

Contract Balances

Contract Assets

Contract assets consist of subscriber assets.  These subscriber assets relate to fees in certain contracts that we charge our customers so they can begin using equipment. In these cases, we retain the ownership of the equipment that the customer uses. The total net book value of subscriber assets of $2.2 million and $2.2 million as of June 30, 2021 and September 30, 2020, respectively, are included in property, equipment and improvements, net. Depreciation expense for these subscriber assets, which is included in cost of sales, was $0.5 million and $0.4 million for the three months ended June 30, 2021 and June 30, 2020, respectively and $1.4 million and $1.1 million for the nine months ended June 30, 2021 and June 30, 2020, respectively. We depreciate the cost of this equipment over its useful life (typically three years).

Contract Liabilities

The timing of revenue recognition may differ from the timing of invoicing to customers. Customers are invoiced for subscription services in advance on a monthly, quarterly or annual basis. Contract liabilities consist of unearned revenue related to annual or multi-year contracts for subscription services and related implementation fees. These pertain to our IoT Solutions segment and our Digi Remote Manager® services in our IoT Products & Services segment.

Changes in unearned revenue were (in thousands):

	Three months ended June 30,				Nine months ended June 30,
	2021		2020		2021		2020
Unearned revenue, beginning of period	$	16,436	$	8,702	$	9,341	$	5,025

Revenue recognized	(10,775)		(7,530)		(31,693)		(23,407)
Unearned revenue, end of period	$	14,841	$	6,428	$	14,841	$	6,428

Remaining Transaction Price

Transaction price allocated to the remaining performance obligations represents contracted revenue that has not been recognized. This includes unearned revenue and unbilled amounts that will be recognized as revenue in future periods. As of

17

June 30, 2021, approximately $14.8 million of revenue is expected to be recognized from remaining performance obligations for subscription contracts. We expect to recognize revenue on approximately $13.0 million of remaining performance obligations over the next twelve months. Revenue from the remaining performance obligations we expect to recognize over a range of two to seven years.

11. INCOME TAXES

Our income tax expense was $0.2 million for the nine months ended June 30, 2021. Included in this expense was a net tax benefit discretely related to the nine months ended June 30, 2021 of $1.0 million. This benefit primarily was the result of excess tax benefits recognized on stock compensation.

Income tax benefit was $0.9 million for the nine months ended June 30, 2020. Included in this benefit was a net tax benefit discretely related to the nine months ended June 30, 2020 of $1.1 million. This benefit primarily was the result of excess tax benefits recognized on stock compensation and an adjustment of our state deferred tax rate due to the Opengear acquisition. For the nine months ended June 30, 2020, our effective tax rate before items discretely related to the period was less than the U.S. statutory rate. This was primarily due to certain research and development tax credits generated in the U.S.

Our effective tax rate will vary based on a variety of factors. These include our overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and tax items discretely related to the period, such as settlements of audits. We may record other benefits or expenses in the future that are specific to a particular quarter such as expiration of statutes of limitation, the completion of tax audits, or legislation that is enacted in both U.S. and foreign jurisdictions.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):

Unrecognized tax benefits as of September 30, 2020	$	2,600
Decreases related to:
Expiration of statute of limitations	(209)
Unrecognized tax benefits as of June 30, 2021	$	2,391

The total amount of unrecognized tax benefits at June 30, 2021 that, if recognized, would affect our effective tax rate was $2.2 million, after considering the impact of interest and deferred benefit items. We expect that the total amount of unrecognized tax benefits will decrease by approximately $0.1 million over the next 12 months.

12. PRODUCT WARRANTY OBLIGATION

The following tables summarize the activity associated with the product warranty accrual (in thousands) and is included on our condensed consolidated balance sheets within current liabilities:

	Balance at		Warranties		Settlements		Balance at

Nine months ended June 30, 2020	$	1,012	$	525	$	(650)	$	887

13. LEASES

All of our leases are operating leases and primarily consist of leases for office space. For any lease with an initial term in excess of twelve months, the related lease assets and lease liabilities are recognized on the condensed consolidated balance sheets as either operating or financing leases at the inception of an agreement where it is determined that a lease exists. We have lease agreements that contain both lease and non-lease components. We have elected to combine lease and non-lease

18

components for all classes of assets. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheets. Instead we recognize lease expense for these leases on a straight-line basis over the lease term.

Operating lease assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments. These assets and liabilities are recognized based on the present value of future payments over the lease term at the commencement date. We generally use a collateralized incremental borrowing rate based

on information available at the commencement date, including the lease term, in determining the present value of future payments. When determining our right-of-use asset, we generally do not include options to extend or terminate the lease unless it is reasonably certain that the option will be exercised.

Our leases typically require payment of real estate taxes and common area maintenance and insurance. These components comprise the majority of our variable lease cost and are excluded from the present value of our lease obligations. Fixed payments may contain predetermined fixed rent escalations. We recognize the related rent expense on a straight-line basis from the commencement date to the end of the lease term.

The following table shows the supplemental balance sheet information related to our leases (in thousands):

	Balance Sheet Location	June 30, 2021		September 30, 2020

14. RESTRUCTURING

Q1 FY2021 Restructuring

On October 7, 2020, our Board of Directors approved a reorganization of our IoT Products & Services business segment. The restructuring plan aligns the business segment's organization around product lines. Under this plan, we recorded a charge of $0.7 million for employee termination charges and eliminated 19 employment positions primarily in the U.S. during the three months ended December 31, 2020. In the second quarter of fiscal 2021 we recorded an additional $0.2 million related to this restructuring. In the third quarter of fiscal 2021 we recorded an additional $0.1 million related to this restructuring.

Below is a summary of the restructuring charges and other activity (in thousands):

15. COMMITMENTS AND CONTINGENCIES

Leases

We lease certain of our buildings and equipment under noncancelable lease agreements. Please refer to Note 13 to our condensed consolidated financial statements for additional information.

Litigation

In November 2018, DimOnOff Inc., a company headquartered in Quebec City, Quebec, Canada ("DimOnOff"), which sells control systems in the building automation and street lighting markets sued us and a former distributor from whom DimOnOff purchased certain Digi products. The suit was brought in the Superior Court of the Province of Quebec in the District of Quebec (Canada) and alleges certain Digi products it purchased and incorporated into street lighting systems in a Canadian city were defective causing some of the street lights to malfunction.  It alleged damages of just over CAD 1.0 million.  During the

20

15. COMMITMENTS AND CONTINGENCIES (CONTINUED)

second quarter of fiscal 2021, the lawsuit was settled and no payment will be made by us. However, we will be providing DimOnOff reduced product pricing on a limited number of products for an amount substantially lower than what was claimed in the lawsuit.

In addition to the matter discussed above, in the normal course of business, we are presently, and expect in the future to be, subject to various claims and litigation with third parties such as non-practicing intellectual property entities as well as customers, vendors and/or employees. There can be no assurance that any claims by third parties, if proven to have merit, will not materially adversely affect our business, liquidity or financial condition.

16. STOCK-BASED COMPENSATION

Stock-based awards were granted under the 2021 Omnibus Incentive Plan (the "2021 Plan") beginning January 29, 2021. Prior to that date, such awards made in fiscal 2021 were granted under the 2020 Omnibus Incentive Plan (the "2020 Plan"). Upon stockholder approval of the 2021 Plan, we ceased granting awards under the 2020 Plan. Shares subject to awards under the 2020 Plan or any prior plans that are forfeited, canceled, returned to us for failure to satisfy vesting requirements, settled in cash or otherwise terminated without payment also will be available for grant under the 2021 Plan. The authority to grant options under the 2021 Plan and set other terms and conditions rests with the Compensation Committee of the Board of Directors.

The 2021 Plan authorizes the issuance of up to 1,400,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants include our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options that have been granted under the 2021 Plan typically vest over a four-year period and will expire if unexercised after seven years from the date of grant. Restricted stock unit awards ("RSUs") that have been granted to directors typically vest in one year. RSUs that have been granted to executives and employees typically vest in January over a four-year period. Performance stock unit awards ("PSUs") that have been granted to an executive will vest based on achievement of a cumulative adjusted earnings per share metric measured over a three-year period. Share-based compensation expenses recorded for this performance award is reevaluated at each reporting period based on the probability of achievement of the goal. The 2021 Plan is scheduled to expire on January 28, 2031. Options under the 2021 Plan can be granted as either incentive stock options or non-statutory stock options. The exercise price of options and the grant date price of RSUs and PSUs is determined by our Compensation Committee but will not be less than the fair market value of our common stock based on the closing price as of the date of grant. Upon exercise of options or settlement of vested restricted stock units or performance stock units, we issue new shares of stock. As of June 30, 2021, there were approximately 1,325,088 shares available for future grants under the 2021 Plan.

Cash received from the exercise of stock options was $7.0 million and $5.1 million for the nine months ended June 30, 2021 and June 30, 2020, respectively.

Our equity plans and corresponding forms of award agreements generally have provisions allowing employees to elect to satisfy tax withholding obligations through the delivery of shares. When employees make this election, we retain a portion of shares issuable under the award. Tax with withholding obligations otherwise occur by the employee paying cash to us for the withholding. During the nine months ended June 30, 2021 and 2020, our employees forfeited 109,516 shares and 95,997 shares, respectively, in order to satisfy respective withholding tax obligations of $2.0 million and $1.7 million.

We sponsor an Employee Stock Purchase Plan as amended and restated as of December 10, 2019, October 29, 2013, December 4, 2009 and November 27, 2006 (the "ESPP"), covering all domestic employees with at least 90 days of continuous service and who are customarily employed at least 20 hours per week. The ESPP allows eligible participants the right to purchase common stock on a quarterly basis at the lower of 85% of the market price at the beginning or end of each three-month offering period. The most recent amendments to the ESPP, ratified by our stockholders on January 29, 2020, increased the total number of shares to 3,425,000 that may be purchased under the plan. ESPP contributions by employees were $0.9 million for the nine months ended June 30, 2021 and $0.8 million for the nine months ended June 30, 2020. Pursuant to the ESPP, 61,302 and 90,592 common shares were issued to employees during the nine months ended June 30, 2021 and June 30, 2020, respectively. Shares are issued under the ESPP from treasury stock. As of June 30, 2021, 650,412 common shares were available for future issuances under the ESPP.

Stock Options

The following table summarizes our stock option activity (in thousands, except per common share amounts):

	Options Outstanding	Weighted Average Exercised Price	Weighted Average Contractual Term (in years)	Aggregate Intrinsic Value (1)
Balance at September 30, 2020	3,393	$12.20
Granted	497	17.58
Exercised	(625)	11.24
Forfeited / Canceled	(142)	14.18
Balance at March 31, 2021	3,123	$13.16	3.91	$	21,864
Exercisable at March 31, 2021	1,949	$11.52	2.86	$	16,745

(1) The aggregate intrinsic value represents the total pre-tax intrinsic value, based on our closing stock price of $20.11 as of June 30, 2021, which would have been received by the option holders had all option holders exercised their options as of that date. The intrinsic value of an option is the amount by which the fair value of the underlying stock exceeds its exercise price.

The total intrinsic value of all options exercised during the nine months ended June 30, 2021 was $5.4 million and during the nine months ended June 30, 2020 was $3.4 million.

The following table shows the weighted average fair value, which was determined based upon the fair value of each option on the grant date utilizing the Black-Scholes option-pricing model and the related assumptions:

	Nine months ended June 30,
	2021	2020
Weighted average per option grant date fair value	$7.45	$6.18
Assumptions used for option grants:
Risk free interest rate	0.51% - 1.035%	0.44% - 1.73%
Expected term	6.00 years	6.00 years
Expected volatility	44% - 46%	42%
Weighted average volatility	44%	36%
Expected dividend yield	—	—

The fair value of each option award granted during the periods presented was estimated using the Black-Scholes option valuation model that uses the assumptions noted in the above table. Expected volatilities are based on the historical volatility of our stock. We use historical data to estimate option exercise and employee termination information within the valuation model. The expected term of options granted is derived from the vesting period and historical information and represents the period of

22

16. STOCK-BASED COMPENSATION (CONTINUED)

time that options granted are expected to be outstanding. The risk-free rate used is the zero-coupon U.S. Treasury bond rate in effect at the time of the grant whose maturity equals the expected term of the option.

As of June 30, 2021, the total unrecognized compensation cost related to non-vested stock options was $6.8 million and the related weighted average period over which it is expected to be recognized is approximately 2.9 years.

Non-vested Stock Units

The following table presents a summary of our non-vested restricted stock and performance stock units as of June 30, 2021 and changes during the nine months then ended (in thousands, except per common share amounts):

	RSUs			PSUs
	Number of Awards	Weighted Average Grant Date Fair Value		Number of Awards	Weighted Average Grant Date Fair Value
Nonvested at September 30, 2020	972	$	13.20	—	$	—

Nonvested at March 31, 2021	875	$	15.48	18	$	25.15

As of June 30, 2021, the total unrecognized compensation cost related to non-vested stock units was $10.8 million. The related weighted average period over which this cost is expected to be recognized is approximately 1.6 years.

17. SUBSEQUENT EVENTS

Acquisition of Ctek, Inc.

On July 6, 2021, we acquired Ctek, Inc. ("Ctek"), a San Pedro, California-based provider that specializes in solutions for remote monitoring and industrial controls. The results of operations of Ctek will be included in our fourth quarter fiscal 2021 results within our IoT Products & Services segment.

The terms of the acquisition included an upfront cash payment as well as contingent consideration comprised of future earn-out payments. We funded the closing of the acquisition with $12.0 million of cash on hand. The future earn-out payments are based on revenue performance outlined in the terms of the purchase agreement for the annual periods ending December 31, 2021, December 31, 2022 and December 31, 2023. The cumulative amount of these earn-outs for the annual periods will not exceed $0.5 million, $1.0 million and $1.5 million, respectively. Due to the timing of the acquisition, the purchase price allocation, including related determinations of fair value and income tax implications, are in process.

For tax purposes, this acquisition is treated as a stock acquisition. The goodwill therefore is not deductible. Through the acquisition of Ctek, Digi is uniquely positioned to provide customers with both battery and hardwired options for the control and monitoring of critical infrastructure, from complex off-shore oil rig locations to localized deployments such as municipal park lighting. In addition, Ctek’s offering and existing client portfolio is set to further Digi’s reach in a rapidly expanding market.

Costs directly related to the acquisition of $0.2 million incurred in the third quarter of fiscal 2021 have been charged to operations and are included in general and administrative expense in our condensed statements of operations. These acquisition costs include legal, accounting, valuation and investment banking fees.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Our management's discussion and analysis should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2020, as well as our subsequent reports on Form 10-Q and Form 8-K and any amendments to these reports.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Form 10-Q contains certain statements that are "forward-looking statements" as that term is defined under the Private Securities Litigation Reform Act of 1995, and within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

Forward-Looking Statements

The words such as "assume," "believe," "anticipate," "intend," "estimate," "target," "may," "will," "expect," "plan," "potential," "project," "should," or "continue" or the negative thereof or other expressions, which are predictions of or indicate future events and trends and which do not relate to historical matters, identify forward-looking statements. Among other items, these statements relate to expectations of the business environment in which Digi operates, projections of future performance, perceived marketplace opportunities and statements regarding our mission and vision. Such statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions. Among others, these include risks related to the ongoing COVID-19 pandemic and efforts to mitigate the same, risks related to global economic volatility and the ability of companies like us to operate a global business in such conditions, the current supply chain and shipping market pressures that are negatively impacting both manufacturing and distribution timelines as well as operating costs for a wide range of companies globally, the highly competitive market in which our company operates, rapid changes in technologies that may displace products sold by us, declining prices of networking products, our reliance on distributors and other third parties to sell our products, the potential for significant purchase orders to be canceled or changed, delays in product development efforts, uncertainty in user acceptance of our products, the ability to integrate our products and services with those of other parties in a commercially accepted manner, potential liabilities that can arise if any of our products have design or manufacturing defects, our ability to defend or settle satisfactorily any litigation, uncertainty in global economic conditions and economic conditions within particular regions of the world which could negatively affect product demand and the financial solvency of customers and suppliers, the impact of natural disasters and other events beyond our control that could negatively impact our supply chain and customers, potential unintended consequences associated with restructuring, reorganizations or other similar business initiatives that may impact our ability to retain important employees or otherwise impact our operations in unintended and adverse ways, the ability to achieve the anticipated benefits and synergies associated with acquisitions or divestitures and changes in our level of revenue or profitability which can fluctuate for many reasons beyond our control.

These and other risks, uncertainties and assumptions identified from time to time in our filings with the United States Securities and Exchange Commission, including without limitation, our Annual Report on Form 10-K for the year ended September 30, 2020, this filing on Form 10-Q and other filings, could cause our actual results to differ materially from those expressed in any forward-looking statements made by us or on our behalf. Many of such factors are beyond our ability to control or predict. These forward-looking statements speak only as of the date for which they are made. We disclaim any intent or obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, the disclosure of contingent assets and liabilities and the values of purchased assets and assumed liabilities in acquisitions. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

A description of our critical accounting policies and estimates was provided in the Management's Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

OVERVIEW

We are a leading global provider of business and mission-critical Internet-of-Things ("IoT") connectivity products, services and solutions comprised of two reporting segments: IoT Products & Services and IoT Solutions.

Our IoT Products & Services segment offers products and services that help original equipment manufacturers ("OEMs"), enterprise and government customers create and deploy, secure IoT connectivity solutions. From embedded and wireless modules to console servers, enterprise and industrial routers, we provide customers with a wide variety of communication sub-assemblies and finished products to meet their IoT communication requirements. In addition, the IoT Products & Services segment provides our customers with a device management platform and other professional services to enable customers to capture and manage data from devices they connect to networks.

Our IoT Solutions segment offers wireless temperature and other condition-based monitoring services as well as task management services. These solutions are focused on the following vertical markets: food service, retail, healthcare, transportation/logistics and education. These solutions are marketed as SmartSense by Digi®. We have formed, expanded and enhanced the IoT Solutions segment through four acquisitions.

We compete for customers on the basis of existing and planned product features, service and software application capabilities, company reputation, brand recognition, technical support, alliance relationships, quality and reliability, product development capabilities, price and availability.

On October 7, 2020, our Board of Directors approved a reorganization of our IoT Products & Services business segment. The restructuring plan aligned the business segment's organization around product lines, each with a segment manager. Under this plan, we recorded charges of $1.0 million for employee termination charges and eliminated 19 employment positions primarily in the U.S. during the first half of fiscal 2021. We have grouped our products under the following categories: Cellular Routers, Console Servers, OEM Solutions and Infrastructure Management. Consequently, the measure of segment operating profit used by our chief operating decision maker ("CODM") changed. As a result, our disclosed measure of segment operating income has been updated. For further detail on segment performance, see the Revenue by Segment, Cost of Goods Sold and Gross Profit by Segment and Operating Income sections of this Item 2.

In fiscal 2021, our key operating objectives include:

•continued growth of our SmartSense by Digi® business that is the base of our IoT Solutions segment;

•delivering growth within our IoT Products & Services segment through new product introductions and efforts to grow recurring revenue streams; and

•identification of strategic growth initiatives through acquisition.

We utilize many financial, operational, and other metrics to evaluate our financial condition and financial performance. Below we highlight the metrics for the third quarter of fiscal 2021 that we feel are most important in these evaluations:

•Consolidated revenue increased $8.7 million, or 12.4% in the third quarter of fiscal 2021 compared to the third quarter of fiscal 2020.

•Gross margin increased as a percentage of revenue to 53.8% in the third quarter of fiscal 2021 as compared to 53.1% in the third quarter of fiscal 2020.

•Net income for the third fiscal quarter of 2021 was $3.2 million, or $0.09 per diluted share. Net income for the third fiscal quarter of 2020 was $1.8 million, or $0.06 per diluted share. Adjusted net income and adjusted net income per share was $8.7 million, or $0.25 per diluted share. In the third fiscal quarter of fiscal 2020, adjusted net income and adjusted net income per share was $6.6 million, or $0.23 per diluted share.

•Adjusted EBITDA for the third fiscal quarter of 2021 was $11.6 million, or 14.6% of total revenue. In the third fiscal quarter of fiscal 2020, Adjusted EBITDA was $10.5 million, or 15.0% of total revenue.

Impact of Global Events and Conditions on Our Business Results and Operations

25

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Global Supply Chain and Freight Transportation Disruptions

Like many companies, we are experiencing disruptions in our supply chain. This has led to shortfalls in available components we need to make products and well as increased costs both to obtain components and to transport components and products. It has also lengthened the timelines for us to fulfill customer orders. The severity of the disruptions is continuously changing, meaning the impact on our ability to meet demand for particular products in a timely manner has been subject to ebb and flow. We are taking steps to attempt to mitigate the impact of the disruptions such as placing inventory demand further out into the future to secure our allocations of components, encouraging customers to place orders earlier than normal due to longer lead times and attempting (in conjunction with customers) to influence political leaders to assure components needed to make products that are essential to the health and well-being of society are prioritized to our customer’s needs by suppliers. At present the ongoing duration and severity of these disruptions we are unable to predict as is the ultimate impact on our business and financial results, which could be material.

Ongoing Covid-19 Pandemic Impacts

The ongoing pandemic and related global economic volatility continues to create significant uncertainty regarding the nearer term outlook for the markets where we provide products and services. While the rollout of vaccines is well underway in many parts of the world, the pandemic (including the recent spread of more contagious variants of the virus) and related economic volatility it has caused still represents a fluid situation that presents a wide and changing range of potential impacts on our own business and those of our customers, vendors and other business partners. As our products and services serve companies across a broad range of industries, in some instances demand has increased or appears to be returning to levels associated with pre-pandemic conditions while others continue to be depressed. At present, the duration, severity and impact of the pandemic in various locations globally as well as the impacts of related economic volatility remain unclear.

During fiscal 2020, we took steps to lower our operating expenses as a result of the pandemic and related economic volatility. We continue to monitor the impacts of COVID-19 on our operations closely. As conditions change we could take steps to increase or decrease expenses as we believe circumstances warrant. Since the start of the pandemic there have not been any material adverse changes to our assets on our balance sheet and, at present, we do not expect there to be material adverse changes. During the nine months of fiscal 2021, we reviewed the potential impacts of the COVID-19 pandemic on goodwill and intangible assets and determined there to be no material impact at that time. We also reviewed the potential impacts on future risks to the business as it relates to collections, returns and other business related items. No significant changes to these reserves have been made.

We also have taken a range of actions with respect to how we operate to assure we comply with government restrictions and guidelines as well as other practices to protect the health and well-being of our employees and our ability to continue operating our business effectively. To date, we have been able to operate our business using these measures and to maintain effectively all internal controls as documented and posted. We also have not experienced challenges in maintaining business continuity and do not expect to incur material expenditures to do so. However, the impacts of the pandemic and efforts to mitigate the same remain fluid and it remains possible that challenges may arise in the future.

Recent Events Impacting Third Quarter Results

Acquisition of Haxiot, Inc.

On March 26, 2021, we acquired Haxiot, Inc. ("Haxiot") a Dallas-based provider of low power wide area ("LPWA") wireless technology. We funded the closing of the acquisition with $7.1 million cash on hand. In fiscal third quarter, the purchase price allocation was recorded , including related determinations of fair value and income tax implications. as a result, we recorded $8.6 million of goodwill and adjusted the contingent consideration to $5.9 million on our balance sheet. The results of operations are now included in our third quarter fiscal 2021 results within our IoT Products & Services segment.

IoT Products & Services

IoT Products & Services revenue increased 5.3% for the three months ended June 30, 2021 as compared to the same period in the prior fiscal year. This primarily was a result of:

•increased sales of our console servers primarily due revenue from our acquisition of Opengear in December 2019; and

•increased sales within our embedded portfolio attributable to demand from a specific medical device customer

This increase partially offset by:

•decreased sales of our cellular routers,

IoT Products & Services revenue increased 5.0% for the nine months ended June 30, 2021 as compared to the same period in the prior fiscal year. This primarily was a result of:

•increased sales of our console servers primarily due to incremental revenue from our acquisition of Opengear in December 2019; and

•increased revenue from embedded and Xbee® products.

This increase partially was offset by:

•decreased sales of our cellular routers in the government transit sector primarily related to an existing customer in the prior year that was not repeated this year.

IoT Solutions

IoT Solutions revenue increased 78.6% and 67.1% for the three and nine months ended June 30, 2021, respectively, as compared to the same periods in the prior fiscal year. This primarily was a result of:

•new hardware installations with new and existing customers; and

IoT Product & Services

IoT Products & Services gross profit margin increased 170 basis points for the three months ended June 30, 2021 as compared to the same period in the prior fiscal year. This increase primarily was a result of:

•favorable product and customer mix within and among our console server, cellular router, embedded and Xbee® products.

This increase partially offset by:

•increased material and overhead expenses associated with the production and distribution of our products as a result of global supply chain challenges.

IoT Products & Services gross profit margin increased 320 basis points for the nine months ended June 30, 2021 as compared to the same period in the prior fiscal year. This increase primarily was a result of:

•incremental gross profit from our console servers due to the Opengear acquisition in December 2019; and

•favorable product mix within our cellular router, embedded, Xbee® and infrastructure management products

IoT Solutions

The IoT Solutions gross profit margin decreased (330) basis points for the three months ended June 30, 2021 as compared to the same periods in the prior fiscal year. This increase primarily was a result of:

•increased one time, product revenue, which typically has lower gross margin; and

•increased material and overhead expenses associated with the production and distribution of our products as a result of global supply challenges.

The IoT Solutions gross profit margin decreased (100) basis points for the nine months ended June 30, 2021 as compared to the same period in the prior fiscal year. This decrease primarily was a result of:

•increased material and overhead expenses associated with the production and distribution of our products as a result of global supply challenges.

NM means not meaningful

The $4.0 million increase in operating expenses in the third quarter of fiscal 2021 from the third quarter of fiscal 2020 primarily was the result of:

•an increase of $3.1 million in compensation related expenses primarily related to additional bonus and commission expense due to increased company performance; and

•other increases primarily related bad debt expense and outside services.

The $16.4 million increase in fiscal year-to-date operating expenses for the nine months ending June 30, 2021, when compared to the same period in the prior fiscal year was the result of:

•an increase of $5.9 million in earn-out expenses primarily as a result of revenue from Opengear exceeding our previous estimate; and

•an increase of $8.4 million in compensation expenses primarily related to incremental salaries from the Opengear acquisition in December 2019, and

•other increases primarily related to incremental expenses due to the Opengear acquisition in December 2019, restructuring charges, bad debt expense and outside services.

This increase partially was offset by:

•a decrease of $1.7 million in M&A expense; and

•a decrease of $1.9 million in travel related expenses as events and travel were restricted due to the pandemic.

OPERATING INCOME

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Operating income was $4.0 million for the three months ended June 30, 2021, compared to $2.9 million for three months ended June 30, 2020. Operating income was $7.2 million for the nine months ending June 30, 2021, compared to $6.1 million for the nine months ending June 30, 2020.

IoT Product & Services provided operating income of $6.1 million for the three months ended June 30,2021 compared to $4.8 million for the three months ended June 30, 2020, an increase of $1.3 million, or 27.4%. IoT Product & Services provided operating income of $4.7 million for the nine months ending June 30, 2021 compared to $14.5 million for the nine months ending June 30, 2020, a decrease of $9.8 million, or 67.3%. Drivers for the changes e in operating income for both the quarter and year-to-date periods are described above in the revenue, gross profit and operating expenses details.

IoT Solutions had an operating loss of $2.1 million for the three months ended June 30, 2021 compared to an operating loss of $1.9 million for the three months ended June 30, 2020, a decrease of $0.2 million, or 7.8%. IoT Solutions had operating income of $2.5 million for the nine months ending June 30, 2021 compared to an operating loss of $8.4 million for the nine months ending June 30, 2020, an improvement of $10.9 million, or 129.8%.

Other expense, net, improved $0.5 million and $1.7 million for the three and nine months periods ended June 30, 2021, respectively, as compared to the same periods in the prior fiscal year. The improvement was primarily due to the decrease interest expense as we paid down our term loan and paid off our revolving loan under the prior Credit Facility and subsequently in March 2021, refinanced the balance of our term loan with a revolving loan. (see Note 7 to the condensed consolidated financial statements).

INCOME TAXES

See Note 11 to the condensed consolidated financial statements for discussion of income taxes.

NON-GAAP FINANCIAL INFORMATION

This report includes adjusted net income, adjusted net income per diluted share and adjusted earnings before interest, taxes and amortization ("Adjusted EBITDA"), each of which is a non-GAAP financial measure.

We understand that there are material limitations on the use of non-GAAP measures. Non-GAAP measures are not substitutes for GAAP measures, such as net income, for the purpose of analyzing financial performance. The disclosure of these measures does not reflect all charges and gains that were actually recognized by Digi. These non-GAAP measures are not in accordance with, or, an alternative for measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies or presented by us in prior reports. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. We believe that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP. We believe these measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. Additionally, Adjusted EBITDA does not reflect our cash expenditures, the cash requirements for the replacement of depreciated and amortized assets, or changes in or cash requirements for our working capital needs.

We believe that providing historical and adjusted net income and adjusted net income per diluted share, respectively, exclusive of such items as reversals of tax reserves, discrete tax benefits, restructuring charges and reversals, intangible amortization, stock-based compensation, other non-operating income/expense, changes in fair value of contingent consideration, acquisition-related expenses and interest expense related to acquisitions permits investors to compare results with prior periods that did not

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

include these items. Management uses the aforementioned non-GAAP measures to monitor and evaluate ongoing operating results and trends and to gain an understanding of our comparative operating performance. In addition, certain of our stockholders have expressed an interest in seeing financial performance measures exclusive of the impact of these matters, which while important, are not central to the core operations of our business. Management believes that Adjusted EBITDA, defined as EBITDA adjusted for stock-based compensation expense, acquisition-related expenses, restructuring charges and reversals, and changes in fair value of contingent consideration is useful to investors to evaluate the Company's core operating results and financial performance because it excludes items that are significant non-cash or non-recurring items reflected in the condensed consolidated ctatements of cperations. We believe that the presentation of Adjusted EBITDA as a percentage of revenue is useful because it provides a reliable and consistent approach to measuring our performance from year to year and in assessing our performance against that of other companies. We believe this information helps compare operating results and corporate performance exclusive of the impact of our capital structure and the method by which assets were acquired.

Below are reconciliations from GAAP to Non-GAAP information that we feel is important to our business:

(2)For the three and nine months ended June 30, 2021, discrete tax benefits primarily are a result of excess tax benefits recognized on stock compensation. For the three months ended June 30, 2020, discrete tax benefits were primarily a result of excess tax benefits on stock compensation. For the nine months ended June 30, 2020, discrete tax benefits were primarily a result of excess tax benefits on stock compensation and an adjustment of our state deferred tax rate due to the Opengear acquisition.

(3)Adjusted net income per diluted share may not add due to the use of rounded numbers.

LIQUIDITY AND CAPITAL RESOURCES

Historically we have financed our operations and capital expenditures principally with funds generated from operations. Our liquidity requirements arise from our working capital needs, and to a lesser extent, our need to fund capital expenditures to support our current operations and facilitate growth and expansion.

On March 15, 2021, we entered into an amended and restated credit agreement consisting of a $200 million revolving loan. The $47.5 million term loan outstanding from the prior credit agreement was replaced by this new revolving loan along with additional proceeds of $0.6 million for a total of $48.1 million at June 30, 2021. As of June 30, 2021, $151.9 million remained available under the Revolving Loan, which included $10 million available for a letter of credit subfacility and $10 million available under a swingline subfacility, the outstanding amounts of which decrease the available commitment. During the first quarter of fiscal 2021, we repaid the final $15 million of the Revolving Loan under the prior credit agreement. For additional information regarding the terms of our Credit Facility, including the Revolving Loan and its subfacilities, see Note 7 to our condensed consolidated financial statements. Additionally, during the second quarter of fiscal 2021 we sold 4,0258,000 shares of our common stock and received net proceeds of $73.8 million.

We expect positive cash flows from operations for the foreseeable future. We believe that our current cash and cash equivalents balances, cash generated from operations and our ability to borrow under our credit facility will be sufficient to fund our business operations and capital expenditures for the next twelve months and beyond. As follows, our condensed consolidated statements of cash flows for the nine months ended June 30, 2021 and 2020 is summarized:

Effect of exchange rate changes on cash and cash equivalents	(1,893)		1,710
Net increase (decrease) in cash and cash equivalents	$	92,813	$	(37,707)

Cash flows from operating activities increased $22.9 million primarily as a result of:

•increased changes in operating assets and liabilities (net of acquisitions) of $2.4 million. This primarily was due to a decrease in accounts receivable due to ramped up collections in the current fiscal year in addition to increased accounts receivable in the prior fiscal year; and

•a decrease in net income of $1.9 million and non-cash adjustments of $18.1 million. These non-cash adjustments include an accrual for additional earn-out provision and increase depreciation and amortization.

Cash flows from investing activities increased $125.8 million primarily as a result of:

•an increase of $136.1 million related to the purchase of Opengear in the prior fiscal year,

•a partial offset to this decrease was $2.7 million related to the purchase of Haxiot in the current fiscal year and an additional $1.0 million related to purchases of property, equipment, and facilities improvements compared to the prior fiscal year.

Cash flows from financing activities decreased $17.6 million primarily as a result of:

•a decrease of $118.4 million related to proceeds of $119.0 million long-term debt from the Revolving Loan and Term Loan in the prior fiscal year partially offset by proceeds of $0.6 million from the Revolving Loan in the current fiscal year (see Note 7 to the condensed consolidated financial statements);

•a reduction of $24.5 million related to payments on long-term debt;

•an increase of $0.5 million related to the financing portion of acquisition earn-out payments for the Opengear acquisition; and

•a partial offset to these decreases was an increase of $73.8 million due to the proceeds from issuance of common stock (see Note 8 to the condensed consolidated financial statements) and a $1.8 million increase in proceeds from stock award plans.

CONTRACTUAL OBLIGATIONS

The following table summarizes our contractual obligations at June 30, 2021:

	Payments due by fiscal period
($ in thousands)	Total		Less than 1 year		1-3 years		3-5 years		Thereafter
Operating leases	$	25,471	$	2,750	$	6,571	$	5,589	$	10,561

Total	$	83,997	$	6,699	$	12,318	$	54,419	$	10,561

The operating lease agreements included above primarily relate to office space. The table above does not include possible payments for uncertain tax positions. Our reserve for uncertain tax positions, including accrued interest and penalties, was $2.5 million as of June 30, 2021. Due to the nature of the underlying liabilities and the extended time often needed to resolve income tax uncertainties, we cannot make reliable estimates of the amount or timing of future cash payments that may be required to settle these liabilities. The above table also does not include those obligations for royalties under license agreements

33

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

as these royalties are calculated based on future sales of licensed products and we cannot make reliable estimates of the amount of cash payments.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

For information on new accounting pronouncements, see Note 1 to our condensed consolidated financial statements.

34

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to ongoing market risk related to changes in interest rates and foreign currency exchange rates.

INTEREST RATE RISK

We are exposed to market risks related to fluctuations in interest rates on amounts borrowed under the Credit Facility. As of June 30, 2021, we had $48.1 million outstanding under our Revolving Loan. Borrowings under the Credit Facility bear a variable interest rate of LIBOR plus an applicable margin spread from 1.25% to 3.25%. The amount of the applicable margin spread is a function of our leverage ratio and is reset monthly. Based on the balance sheet position for the Revolving Loan at June 30, 2021, the annualized effect of a 25 basis point change in interest rates would increase or decrease our interest expense by $0.1 million. For additional information, see Note 7 to our condensed consolidated financial statements. For our Credit Facility, interest rate changes generally do not affect the fair value of the debt instruments, but do impact future earnings and cash flows, assuming other factors are held constant.

FOREIGN CURRENCY RISK

We are not exposed to foreign currency transaction risk associated with sales transactions as the majority of our sales are denominated in U.S. Dollars. We are exposed to foreign currency translation risk as the financial position and operating results of our foreign subsidiaries are translated into U.S. Dollars for consolidation. We manage our net asset or net liability position for non-functional currency accounts, primarily the U.S. Dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy.

A 10% change in the average exchange rate for the Euro, British Pound, Japanese Yen and Canadian Dollar to the U.S. Dollar during the first nine months of fiscal 2021 would have resulted in a 0.7% increase or decrease in stockholders' equity due to foreign currency translation.

CREDIT RISK

We have exposure to credit risk related to our accounts receivable portfolio. Exposure to credit risk is controlled through regular monitoring of customer financial status, credit limits and collaboration with sales management and customer contacts to facilitate payment.

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, we conducted an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act")). Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2021 that have materially affected, or are reasonably likely to affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The disclosure set forth under the heading "Litigation" in Note 15 to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q is incorporated herein by reference.

35

ITEM 1A. RISK FACTORS

Except as noted below, there have been no material changes in our risk factors from those previously disclosed in Item 1A of Part I of our Annual Report on Form 10-K for the year ended September 30, 2020.

We depend on manufacturing relationships and on limited-source suppliers, and any disruptions in these relationships may cause damage to our customer relationships.

We procure all parts and certain services involved in the production of our products and subcontract most of our product manufacturing to outside firms that specialize in such services. Although most of the components of our products are available from multiple vendors, we have several single-source supplier relationships, either because alternative sources are not available or because the relationship is advantageous to us. Further, the COVID-19 pandemic has created stress on many supply chains globally. This has had some impact on our own ability to procure certain inventory and services. Prior to our first quarter of fiscal 2021 these impacts were generally small and contained. More recently we have seen more significant shortages and higher prices in our ability to procure certain inventory. In addition, shipping costs have recently increased significantly as well. We do expect these shortages and higher costs to have some impact on our business in upcoming quarters, although the severity and duration of the impacts is not clear at this time they could potentially be material. There can be no assurance that our suppliers will be able to meet our future requirements for products and components in a timely fashion. In addition, the availability and cost of many of these components to us is dependent in part on our ability to provide our suppliers with accurate forecasts of our future requirements. Delays or lost revenue could be caused by other factors beyond our control, including late deliveries by vendors of components, or force majeure events such as the ongoing pandemic. As an example of force majeure, a fire in November 2014 disrupted the operations at one of our contract manufacturers in Thailand. If we are required to identify alternative suppliers for any of our required components, qualification and pre-production periods could be lengthy and may cause an increase in component costs and delays in providing products to customers. Any extended interruption in the supply of any of the key components currently obtained from limited sources could disrupt our operations and have a material adverse effect on our customer relationships and profitability.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

("we", "us", "our", "Digi" or "the Company") have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission applicable to interim financial statements. While these financial statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. These financial statements should be read in conjunction with the financial statement disclosures in our Annual Report on Form 10-K for the year ended September 30, 2020 (the "2020 Financial Statements"). We use the same accounting policies in preparing quarterly and annual financial statements. The quarterly results of operations are not necessarily indicative of the results to be expected for the full year.

As described in Note 9, effective with the reorganization announcement on October 7, 2020, the measure of segment operating income (loss) used by our chief operating decision maker ("CODM") changed. As a result, our disclosed measure of segment operating income (loss) has been updated.

Potential Impacts of COVID-19 on our Business

The impact of the coronavirus ("COVID-19") pandemic continues to unfold. The extent of the pandemic's effect on our operational and financial performance will depend in large part on future developments, which cannot be reasonably estimated at this time. Future developments include the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact both within and outside the jurisdictions where we operate, the impact on governmental programs and budgets, the development of treatments or vaccines, and the timing and level of resumption of widespread economic activity. Due to the inherent uncertainty of the unprecedented and rapidly evolving situation, we are unable to predict with any confidence the likely impact of the COVID-19 pandemic on our future operations. For a more detailed discussion see Part I, Item 1 in our Annual Report on Form 10-K for the year ended September 30, 2020 and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Item 2 of this Form 10-Q.

Recently Issued Accounting Pronouncements

Adopted

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820).  The updated guidance changes the disclosure requirements on fair value measurements. We adopted this standard in the first quarter of fiscal 2021. This standard did not have a material impact on our consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about expected credit losses. We adopted this standard in the first quarter of fiscal 2021, following the modified-retrospective approach. This standard did not have a material impact on our consolidated financial statements.

ACQUISITIONS

ACQUISITIONS

Acquisition of Haxiot, Inc.

On March 26, 2021, we acquired Haxiot, Inc. ("Haxiot"), a Dallas-based provider of low power wide area ("LPWA") wireless technology. The results of operations are now included in our third quarter of fiscal 2021 results within our IoT Products & Services segment.

The terms of the acquisition included an upfront cash payment as well as contingent consideration comprised of future earn-out payments. We funded the closing of the acquisition with $7.1 million of cash on hand. The future earn-out payments are based on Haxiot revenue performance and contractually are not to exceed $3.0 million and $5.0 million for the annual periods ending December 31, 2021 and December 31, 2022. The fair value amount of these earn-outs for the annual periods ending December 31, 2021 and December 31, 2022 are $3.0 million and $2.9 million, respectively. In the fiscal third quarter of fiscal 2021, the preliminary purchase price allocation was updated, including related determination of fair value and income tax implications. As a result, we adjusted goodwill to $8.6 million and adjusted contingent consideration to $5.9 million on our balance sheet at June 30, 2021.

For tax purposes, this acquisition is treated as a stock acquisition. The goodwill therefore is not deductible. We believe this is a complementary acquisition for us as it significantly enhances our IoT Products & Services segment by enhancing Digi's embedded systems portfolio and immediately extends the company's market reach with a complete LoRaWAN®-based solutions offering.

Costs directly related to the acquisition of $0.2 million incurred fiscal year to date 2021 have been charged to operations and are included in general and administrative expense in our condensed statements of operations. These acquisition costs include legal, accounting, valuation and investment banking fees.

The following table summarizes the preliminary fair values of Haxiot assets acquired and liabilities assumed as of the acquisition date (in thousands).

Cash	$	7,146
Contingent consideration	5,900
Total	$	13,046
Fair value of net tangible assets acquired	$	124
Identifiable intangible assets:
Customer relationships	3,900
Purchased and core technology	1,050
Trademarks	500
Deferred tax liability on identifiable intangible assets	(1,145)
Goodwill	8,617
Total	$	13,046

Acquisition of Opengear, Inc.

On December 13, 2019, we completed our acquisition of Opengear, Inc. ("Opengear"), a New Jersey-based provider of secure IT infrastructure products and software. Opengear results have been included in our condensed consolidated financial statements within our IoT Products & Services segment since the date of acquisition.

During the first quarter of fiscal 2021, we recorded an out-of-period adjustment in connection with the purchase price accounting of Opengear. This balance sheet adjustment resulted in a decrease in fair value of net tangible assets acquired of $1.1 million, a decrease of $0.3 million to non-current deferred tax liability and an increase to goodwill of $0.8 million. Management assessed the impact of this adjustment and believes, after considering both quantitative and qualitative factors, that it is not material to our current or previously issued consolidated financial statements.

The following table summarizes the final fair values of Opengear assets acquired and liabilities assumed as of the acquisition date (in thousands):

Cash	$	148,058
Contingent consideration	5,100
Total	$	153,158
Fair value of net tangible assets acquired	$	18,096
Identifiable intangible assets:
Customer relationships	79,000
Purchased and core technology	18,100
Trademarks	8,000
Deferred tax liability on identifiable intangible assets	(27,126)
Goodwill	57,088
Total	$	153,158

The condensed consolidated balance sheet as of June 30, 2021 reflects the final allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition.

In connection with our acquisition of Bluenica Corporation ("Bluenica") in October 2015, we agreed to make contingent earn-out payments over a period of up to 4 years, subject to achieving specified revenue thresholds for sales of Bluenica products. We paid the final installment of $2.9 million during the third quarter of fiscal 2020.

In connection with our acquisition of Accelerated Concepts, Inc. ("Accelerated") in January 2018, we agreed to make contingent earn-out payments if specified revenue thresholds for sales of Accelerated products were achieved. We paid the first installment payment of $3.5 million in the third quarter of fiscal 2019. We paid the final installment of $2.4 million in the third quarter of fiscal 2020. The earn-out period for this acquisition ended on January 22, 2020.

In connection with our acquisition of Opengear, we agreed to make contingent payments, based upon certain revenue thresholds (see Note 2 to the condensed consolidated financial statements). We paid the first installment of $0.9 million during the third quarter of fiscal 2020. We paid the final installment of $10.0 million during the second quarter of fiscal 2021.

In connection with our acquisition of Haxiot, we agreed to make contingent earn-out payments, based upon certain revenue thresholds (see Note 2 to the condensed consolidated financial statements). In the fiscal third quarter of fiscal 2021, the preliminary purchase price allocation was updated, including related determination of fair value and income tax implications. As a result, we adjusted goodwill to $8.6 million and adjusted contingent consideration to $5.9 million on our balance sheet at June 30, 2021.

The following table presents a reconciliation of the contingent consideration liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in thousands):

	Three months ended June 30,					Nine months ended June 30,
	2021			2020		2021		2020
Fair value at beginning of period	$	8,000		$	10,379	$	4,228	$	5,407
Contingent consideration recognized for acquired business	—			—		8,000		5,100

Fair value at end of period	$	5,900		$	4,228	$	5,900	$	4,228

* The change in fair value for the three months ended June 30, 2021, totaling ($2,100) represents an adjustment to our preliminary purchase price of Haxiot that does not impact our condensed consolidated statement of operations.

The change in fair value of contingent consideration reflects our estimates of the probabilities of achieving the relevant targets and is discounted based on our estimated discount rate. Due to the timing of the acquisition, the fair value of the contingent consideration at June 30, 2021 is based on the probability of achieving the specified revenue thresholds for Haxiot.

Goodwill represents the excess of cost over the fair value of net identifiable assets acquired. Goodwill is quantitatively tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. We continue to have 2 reportable segments, our IoT Products & Services segment and our IoT Solutions segment (see Note 9). Effective with the reorganization announcement on October 7, 2020 (see Note 14), our IoT Products & Services business is now structured to include four reporting units under the IoT Products & Services segment, each with a reporting manager: Cellular Routers, Console Servers, OEM Solutions and Infrastructure Management. We have four reporting units along with our IoT Solutions segment that have been tested individually for impairment.

Due to the reorganization on October 7, 2020 (see Note 14), we performed our fiscal third quarter 2021 annual impairment test by reporting unit. As a result, we tested Cellular Routers, Console Servers, OEM Solutions, Infrastructure Management and IOT Solutions units which constitute separate reporting units for purposes of the ASC 350-20-35 "Goodwill Measurement of Impairment" assessment, which were tested individually for impairment in fiscal third quarter 2021.

For our quantitative goodwill impairment tests, we determine the estimated fair value of each reporting unit and compare it to the carrying value of the reporting unit, including goodwill. If the carrying amount of a reporting unit is higher than its estimated fair value, then an impairment loss must be recognized for the excess. Fair values for the five reporting units were each estimated on a standalone basis using a weighted combination of the income approach and market approach.

6. GOODWILL AND OTHER INTANGIBLE ASSETS, NET (CONTINUED)

The income approach indicates the fair value of a business based on the value of the cash flows the business or asset can be expected to generate in the future. A commonly used variation of the income approach used to value a business is the discounted cash flow (“DCF”) method. The DCF method is a valuation technique in which the value of a business is estimated on the earnings capacity, or available cash flow, of that business. Earnings capacity represents the earnings available for distribution to stockholders after consideration of the reinvestment required for future growth. Significant judgment is required to estimate the amount and timing of future cash flows for each reporting unit and the relative risk of achieving those cash flows.

The market approach indicates the fair value of a business or asset based on a comparison of the business or asset to comparable publicly traded companies or assets and transactions in its industry as well as our prior acquisitions. This approach can be estimated through the guideline company method. This method indicates fair value of a business by comparing it to publicly traded companies in similar lines of business. After identifying and selecting the guideline companies, we make judgments about the comparability of the companies based on size, growth rates, profitability, risk, and return on investment in order to estimate market multiples. These multiples are then applied to the reporting units to estimate a fair value.

Assumptions and estimates to determine fair values under the income and market approaches are complex and often subjective.  They can be affected by a variety of factors. These include external factors such as industry and economic trends. They also include internal factors such as changes in our business strategy and our internal forecasts. Changes in circumstances or a potential event could negatively affect the estimated fair values. We will continue to monitor potential COVID-19 industry and demand impacts as this could potentially affect our cash flows and market capitalization. If our future operating results do not meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicative of a reduction in fair value of one or more of our reporting units, we may be required to record future impairment charges for goodwill.

Results of our Fiscal 2021 Annual Impairment Test

As of June 30, 2021, we had a total of $32.7 million of goodwill for the Enterprise Routers reporting unit, $60.2 million of goodwill for the Console Servers reporting unit, $63.4 million of goodwill for the OEM Solutions reporting unit, $15.4 million of goodwill for the Infrastructure Mgmt. reporting unit and $49.5 million of goodwill for the IoT Solutions reporting unit. At June 30, 2021, fair value exceeded the carrying value by more than 20% for all five reporting units. Implied fair values for both reporting units were each calculated on a standalone basis using a weighted combination of the income approach and market approach. The implied fair values of each reporting unit were added together along with our unallocated assets to get an indicated value of total equity to which a range of indicated value of total equity was derived. This range was compared to the total market capitalization of $686.3 million as of June 30, 2021. This implied a range of control (deficit)/ premiums of (4.5)% to 5.4%. This range of control premiums fell below the control premiums observed in the last five years in the communications equipment industry. As a result, the market capitalization reconciliation analysis proved support for the reasonableness of the fair values estimated for each individual reporting unit.

Debt Disclosure [Abstract]

INDEBTEDNESS

INDEBTEDNESSOn March 15, 2021, we entered into an amended and restated credit agreement with BMO Harris Bank N.A. ("BMO"). This agreement provides us with a senior secured credit facility (the "Credit Facility") consisting of a $200 million revolving loan (the "Revolving Loan"). This loan replaced our syndicated senior secured credit agreement with BMO that was entered into on December 13, 2019 and replaced the remaining balance of our term loan with this new revolver. This prior agreement provided us with committed credit facilities ("Prior Credit Facility") totaling $150 million, which included a $50 million term loan and a $100 million revolving loan. We may use the Revolving Loan for working capital, capital expenditures, restricted payments and acquisitions permitted under the agreement.

Borrowings under the Credit Facility bear a variable interest rate of LIBOR plus an applicable margin spread from 1.25% to 3.25%. The amount of the applicable margin spread is a function of our leverage ratio and is reset monthly. In addition to paying interest on the outstanding balance under the Credit Facility, we are required to pay a commitment fee on the non-utilized commitments thereunder which is also reported in interest expense. Our weighted average interest rate at June 30, 2021 was 0.47%.

The additional debt issuance costs and remaining balance under the Prior Credit Facility totaled $2.6 million and is being amortized using the straight-line method over the term of the loan and reported in interest expense.

The Revolving Loan is due in a lump sum payment at maturity on March 15, 2026. The fair value of the Revolving Loan approximated carrying value at June 30, 2021.

Covenants and Security Interest

The agreements governing the Credit Facility contain a number of covenants. Among other thing, these covenants require us to maintain a certain financial ratio (net leverage ratio and minimum fixed charge ratio). At June 30, 2021, we were in compliance with our debt covenants. Amounts borrowed under the Credit Facility are secured by substantially all of our assets.

SEGMENT INFORMATION

SEGMENT INFORMATION

We have two reportable segments: IoT Products & Services and IoT Solutions. Effective with the reorganization announcement on October 7, 2020 (see Note 14), our IoT Products & Services business is now structured to include four operating segments, each with a segment manager. These four operating segments include:

•Cellular Routers - box devices (fully enclosed) that provide connectivity typically in a place where the device can be plugged in exclusively using cellular communications.

•Console Servers - similar to cellular routers except they are exclusively for edge computing installations and data center applications exclusively using cellular communications.

•OEM Solutions - Original Equipment Manufacturers ("OEM") will be a chip, rather than a boxed device. This can come in the form of a stand-alone chip, or from a systems-on-module ("SOMs"). While cellular connectivity is used, other communication protocols can be used such as Zigbee, Bluetooth or Radio-Frequency ("RF") based on application.

•Infrastructure Management - includes battery operated, cellular enabled connect sensors as well as other types of console server applications that are more Digi Accelerated Linux ("DAL") based than Console Servers. This operating segment has some products that do not use cellular communications, but a large part of this segment does use cellular communications.

9. SEGMENT INFORMATION (CONTINUED)

The four operating segments have similar qualitative and quantitative factors which allow us to aggregate them under the IoT Products & Services reportable segment. The qualitative factors include similar nature of products and services, production process, type or class of customers and methods used to distribute the products. The quantitative factors include similar operating margins. Our CODM reviews and makes business decisions which includes a primary review of operating income but also includes gross profit. Thus, our measure of segment profit or loss used by our CODM changed. The shared general and administrative costs are now allocated to each operating segment. As a result, our disclosed measure of segment operating income has been updated for all periods presented. The change to the business segment operating income aligns with the update to how the CODM assesses performance and allocates resources for our business segments.

Contract Balances

Contract Assets

Contract assets consist of subscriber assets.  These subscriber assets relate to fees in certain contracts that we charge our customers so they can begin using equipment. In these cases, we retain the ownership of the equipment that the customer uses. The total net book value of subscriber assets of $2.2 million and $2.2 million as of June 30, 2021 and September 30, 2020, respectively, are included in property, equipment and improvements, net. Depreciation expense for these subscriber assets, which is included in cost of sales, was $0.5 million and $0.4 million for the three months ended June 30, 2021 and June 30, 2020, respectively and $1.4 million and $1.1 million for the nine months ended June 30, 2021 and June 30, 2020, respectively. We depreciate the cost of this equipment over its useful life (typically three years).

Contract Liabilities

The timing of revenue recognition may differ from the timing of invoicing to customers. Customers are invoiced for subscription services in advance on a monthly, quarterly or annual basis. Contract liabilities consist of unearned revenue related to annual or multi-year contracts for subscription services and related implementation fees. These pertain to our IoT Solutions segment and our Digi Remote Manager® services in our IoT Products & Services segment.

Changes in unearned revenue were (in thousands):

	Three months ended June 30,				Nine months ended June 30,

Unearned revenue, end of period	$	14,841	$	6,428	$	14,841	$	6,428

Remaining Transaction Price

Transaction price allocated to the remaining performance obligations represents contracted revenue that has not been recognized. This includes unearned revenue and unbilled amounts that will be recognized as revenue in future periods. As of

June 30, 2021, approximately $14.8 million of revenue is expected to be recognized from remaining performance obligations for subscription contracts. We expect to recognize revenue on approximately $13.0 million of remaining performance obligations over the next twelve months. Revenue from the remaining performance obligations we expect to recognize over a range of two to seven years.

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

Our income tax expense was $0.2 million for the nine months ended June 30, 2021. Included in this expense was a net tax benefit discretely related to the nine months ended June 30, 2021 of $1.0 million. This benefit primarily was the result of excess tax benefits recognized on stock compensation.

Income tax benefit was $0.9 million for the nine months ended June 30, 2020. Included in this benefit was a net tax benefit discretely related to the nine months ended June 30, 2020 of $1.1 million. This benefit primarily was the result of excess tax benefits recognized on stock compensation and an adjustment of our state deferred tax rate due to the Opengear acquisition. For the nine months ended June 30, 2020, our effective tax rate before items discretely related to the period was less than the U.S. statutory rate. This was primarily due to certain research and development tax credits generated in the U.S.

Our effective tax rate will vary based on a variety of factors. These include our overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and tax items discretely related to the period, such as settlements of audits. We may record other benefits or expenses in the future that are specific to a particular quarter such as expiration of statutes of limitation, the completion of tax audits, or legislation that is enacted in both U.S. and foreign jurisdictions.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):

Unrecognized tax benefits as of September 30, 2020	$	2,600
Decreases related to:
Expiration of statute of limitations	(209)
Unrecognized tax benefits as of June 30, 2021	$	2,391

The total amount of unrecognized tax benefits at June 30, 2021 that, if recognized, would affect our effective tax rate was $2.2 million, after considering the impact of interest and deferred benefit items. We expect that the total amount of unrecognized tax benefits will decrease by approximately $0.1 million over the next 12 months.

Leases [Abstract]

LEASES

LEASESAll of our leases are operating leases and primarily consist of leases for office space. For any lease with an initial term in excess of twelve months, the related lease assets and lease liabilities are recognized on the condensed consolidated balance sheets as either operating or financing leases at the inception of an agreement where it is determined that a lease exists. We have lease agreements that contain both lease and non-lease components. We have elected to combine lease and non-lease

components for all classes of assets. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheets. Instead we recognize lease expense for these leases on a straight-line basis over the lease term.

Operating lease assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments. These assets and liabilities are recognized based on the present value of future payments over the lease term at the commencement date. We generally use a collateralized incremental borrowing rate based

on information available at the commencement date, including the lease term, in determining the present value of future payments. When determining our right-of-use asset, we generally do not include options to extend or terminate the lease unless it is reasonably certain that the option will be exercised.

Our leases typically require payment of real estate taxes and common area maintenance and insurance. These components comprise the majority of our variable lease cost and are excluded from the present value of our lease obligations. Fixed payments may contain predetermined fixed rent escalations. We recognize the related rent expense on a straight-line basis from the commencement date to the end of the lease term.

The following table shows the supplemental balance sheet information related to our leases (in thousands):

Litigation

In November 2018, DimOnOff Inc., a company headquartered in Quebec City, Quebec, Canada ("DimOnOff"), which sells control systems in the building automation and street lighting markets sued us and a former distributor from whom DimOnOff purchased certain Digi products. The suit was brought in the Superior Court of the Province of Quebec in the District of Quebec (Canada) and alleges certain Digi products it purchased and incorporated into street lighting systems in a Canadian city were defective causing some of the street lights to malfunction.  It alleged damages of just over CAD 1.0 million.  During the

second quarter of fiscal 2021, the lawsuit was settled and no payment will be made by us. However, we will be providing DimOnOff reduced product pricing on a limited number of products for an amount substantially lower than what was claimed in the lawsuit.

In addition to the matter discussed above, in the normal course of business, we are presently, and expect in the future to be, subject to various claims and litigation with third parties such as non-practicing intellectual property entities as well as customers, vendors and/or employees. There can be no assurance that any claims by third parties, if proven to have merit, will not materially adversely affect our business, liquidity or financial condition.

Stock-Based Compensation

Share-based Payment Arrangement [Abstract]

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

Stock-based awards were granted under the 2021 Omnibus Incentive Plan (the "2021 Plan") beginning January 29, 2021. Prior to that date, such awards made in fiscal 2021 were granted under the 2020 Omnibus Incentive Plan (the "2020 Plan"). Upon stockholder approval of the 2021 Plan, we ceased granting awards under the 2020 Plan. Shares subject to awards under the 2020 Plan or any prior plans that are forfeited, canceled, returned to us for failure to satisfy vesting requirements, settled in cash or otherwise terminated without payment also will be available for grant under the 2021 Plan. The authority to grant options under the 2021 Plan and set other terms and conditions rests with the Compensation Committee of the Board of Directors.

The 2021 Plan authorizes the issuance of up to 1,400,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants include our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options that have been granted under the 2021 Plan typically vest over a four-year period and will expire if unexercised after seven years from the date of grant. Restricted stock unit awards ("RSUs") that have been granted to directors typically vest in one year. RSUs that have been granted to executives and employees typically vest in January over a four-year period. Performance stock unit awards ("PSUs") that have been granted to an executive will vest based on achievement of a cumulative adjusted earnings per share metric measured over a three-year period. Share-based compensation expenses recorded for this performance award is reevaluated at each reporting period based on the probability of achievement of the goal. The 2021 Plan is scheduled to expire on January 28, 2031. Options under the 2021 Plan can be granted as either incentive stock options or non-statutory stock options. The exercise price of options and the grant date price of RSUs and PSUs is determined by our Compensation Committee but will not be less than the fair market value of our common stock based on the closing price as of the date of grant. Upon exercise of options or settlement of vested restricted stock units or performance stock units, we issue new shares of stock. As of June 30, 2021, there were approximately 1,325,088 shares available for future grants under the 2021 Plan.

Cash received from the exercise of stock options was $7.0 million and $5.1 million for the nine months ended June 30, 2021 and June 30, 2020, respectively.

Our equity plans and corresponding forms of award agreements generally have provisions allowing employees to elect to satisfy tax withholding obligations through the delivery of shares. When employees make this election, we retain a portion of shares issuable under the award. Tax with withholding obligations otherwise occur by the employee paying cash to us for the withholding. During the nine months ended June 30, 2021 and 2020, our employees forfeited 109,516 shares and 95,997 shares, respectively, in order to satisfy respective withholding tax obligations of $2.0 million and $1.7 million.

We sponsor an Employee Stock Purchase Plan as amended and restated as of December 10, 2019, October 29, 2013, December 4, 2009 and November 27, 2006 (the "ESPP"), covering all domestic employees with at least 90 days of continuous service and who are customarily employed at least 20 hours per week. The ESPP allows eligible participants the right to purchase common stock on a quarterly basis at the lower of 85% of the market price at the beginning or end of each three-month offering period. The most recent amendments to the ESPP, ratified by our stockholders on January 29, 2020, increased the total number of shares to 3,425,000 that may be purchased under the plan. ESPP contributions by employees were $0.9 million for the nine months ended June 30, 2021 and $0.8 million for the nine months ended June 30, 2020. Pursuant to the ESPP, 61,302 and 90,592 common shares were issued to employees during the nine months ended June 30, 2021 and June 30, 2020, respectively. Shares are issued under the ESPP from treasury stock. As of June 30, 2021, 650,412 common shares were available for future issuances under the ESPP.

Balance at September 30, 2020	3,393	$12.20
Granted	497	17.58
Exercised	(625)	11.24
Forfeited / Canceled	(142)	14.18
Balance at March 31, 2021	3,123	$13.16	3.91	$	21,864
Exercisable at March 31, 2021	1,949	$11.52	2.86	$	16,745

(1) The aggregate intrinsic value represents the total pre-tax intrinsic value, based on our closing stock price of $20.11 as of June 30, 2021, which would have been received by the option holders had all option holders exercised their options as of that date. The intrinsic value of an option is the amount by which the fair value of the underlying stock exceeds its exercise price.

The total intrinsic value of all options exercised during the nine months ended June 30, 2021 was $5.4 million and during the nine months ended June 30, 2020 was $3.4 million.

The following table shows the weighted average fair value, which was determined based upon the fair value of each option on the grant date utilizing the Black-Scholes option-pricing model and the related assumptions:

	Nine months ended June 30,
	2021	2020
Weighted average per option grant date fair value	$7.45	$6.18
Assumptions used for option grants:
Risk free interest rate	0.51% - 1.035%	0.44% - 1.73%
Expected term	6.00 years	6.00 years
Expected volatility	44% - 46%	42%
Weighted average volatility	44%	36%
Expected dividend yield	—	—

The fair value of each option award granted during the periods presented was estimated using the Black-Scholes option valuation model that uses the assumptions noted in the above table. Expected volatilities are based on the historical volatility of our stock. We use historical data to estimate option exercise and employee termination information within the valuation model. The expected term of options granted is derived from the vesting period and historical information and represents the period of

16. STOCK-BASED COMPENSATION (CONTINUED)

time that options granted are expected to be outstanding. The risk-free rate used is the zero-coupon U.S. Treasury bond rate in effect at the time of the grant whose maturity equals the expected term of the option.

As of June 30, 2021, the total unrecognized compensation cost related to non-vested stock options was $6.8 million and the related weighted average period over which it is expected to be recognized is approximately 2.9 years.

Non-vested Stock Units

The following table presents a summary of our non-vested restricted stock and performance stock units as of June 30, 2021 and changes during the nine months then ended (in thousands, except per common share amounts):

	RSUs			PSUs

SUBSEQUENT EVENTS

Acquisition of Ctek, Inc.

On July 6, 2021, we acquired Ctek, Inc. ("Ctek"), a San Pedro, California-based provider that specializes in solutions for remote monitoring and industrial controls. The results of operations of Ctek will be included in our fourth quarter fiscal 2021 results within our IoT Products & Services segment.

The terms of the acquisition included an upfront cash payment as well as contingent consideration comprised of future earn-out payments. We funded the closing of the acquisition with $12.0 million of cash on hand. The future earn-out payments are based on revenue performance outlined in the terms of the purchase agreement for the annual periods ending December 31, 2021, December 31, 2022 and December 31, 2023. The cumulative amount of these earn-outs for the annual periods will not exceed $0.5 million, $1.0 million and $1.5 million, respectively. Due to the timing of the acquisition, the purchase price allocation, including related determinations of fair value and income tax implications, are in process.

For tax purposes, this acquisition is treated as a stock acquisition. The goodwill therefore is not deductible. Through the acquisition of Ctek, Digi is uniquely positioned to provide customers with both battery and hardwired options for the control and monitoring of critical infrastructure, from complex off-shore oil rig locations to localized deployments such as municipal park lighting. In addition, Ctek’s offering and existing client portfolio is set to further Digi’s reach in a rapidly expanding market.

Costs directly related to the acquisition of $0.2 million incurred in the third quarter of fiscal 2021 have been charged to operations and are included in general and administrative expense in our condensed statements of operations. These acquisition costs include legal, accounting, valuation and investment banking fees.

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820).  The updated guidance changes the disclosure requirements on fair value measurements. We adopted this standard in the first quarter of fiscal 2021. This standard did not have a material impact on our consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about expected credit losses. We adopted this standard in the first quarter of fiscal 2021, following the modified-retrospective approach. This standard did not have a material impact on our consolidated financial statements.
