Management discussion and analysis of financial
condition and results of operations for the
three month period ended September 30, 2025
TABLE OF CONTENTS
INTRODUCTION
As used in this Management Discussion and Analysis (“MD&A”), unless the context indicates or requires otherwise, all references to the “Company”, “Sangoma”, “we”, “us”, or “our” refer to Sangoma Technologies Corporation, together with our subsidiaries, on a consolidated basis as constituted on September 30, 2025. The MD&A is for the three month period ended September 30, 2025 as compared to the same period in the previous year. This MD&A should be read in conjunction with Sangoma’s audited annual consolidated financial statements and related notes as at and for the year ended June 30, 2025 (“Financial Statements”), which have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards”). All amounts are in thousands of United States dollars except where otherwise indicated.
Additional information about us, including copies of our continuous disclosure materials, is available on our website at www.sangoma.com, through the EDGAR website at www.sec.gov or through the SEDAR+ website at www.sedarplus.ca.
This MD&A is dated as of November 10, 2025.
NON-IFRS MEASURES
This MD&A contains references to certain non-IFRS financial measures such as Adjusted EBITDA and Free Cash Flow. These measures are used by management to evaluate the performance of the Company and do not have any meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other reporting issuers. Rather, these measures are provided as additional information to complement those IFRS measures by providing further understanding of our results of operations from management’s perspective should not be considered in isolation nor as a substitute for analysis of our financial information reported under IFRS. These non-IFRS measures are used to provide investors with alternative measures of our operating performance and liquidity and thus highlight trends in our business that may not otherwise be apparent when relying solely on IFRS measures. We also believe that securities analysts, investors and other interested parties frequently use non-IFRS measures to compare issuers. Management also uses non-IFRS measures to facilitate operating performance comparisons from period to period, the preparation of annual operating budgets and forecasts and to determine components of executive compensation. “Adjusted EBITDA” means earnings before income taxes, interest expense (net), share-based compensation, depreciation (including for right-of-use assets), amortization, restructuring and business integration costs, goodwill impairment, change in fair value of consideration payable and loss on sale divestiture of subsidiary. “Free Cash Flow” means cash flows from operating activities less cash used for purchases of property and equipment and capitalized development costs. The reconciliation of the closest IFRS measure to the non-IFRS measure is set out on pages
15 and
17 herein.
FORWARD-LOOKING STATEMENTS
This MD&A contains forward-looking statements, including statements regarding the future success of our business, development strategies and future opportunities. Forward-looking statements are provided for the purpose of presenting information about management’s current expectations and plans relating to the future, and readers are cautioned that such statements may not be appropriate for other purposes. Forward-looking statements include, but are not limited to, statements relating to management’s guidance on revenue and Adjusted EBITDA, expectations regarding demand for the Company’s Products and Services, supply chain dynamics, foreign exchange impacts, cash flows, and other statements that are not historical facts.
Words such as “believe”, “could”, “plan”, “estimate”, “expect”, “will”, “intend”, “may”, “potential”, “should”, and similar expressions are intended to identify forward-looking statements.
Although Sangoma believes that the expectations reflected in these forward-looking statements are reasonable, such statements involve known and unknown risks, uncertainties, and other factors that may cause actual results, performance, or achievements to differ materially from those expressed or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: supply chain disruptions, cost inflation, or shipping delays, the Company’s ability to execute its go-to-market strategy, including expansion of subscription and cloud services, changes in customer demand, churn, or adoption of new technologies, macroeconomic and geopolitical developments, including inflation, interest rates, recessions, political instability, conflicts, trade restrictions, sanctions, or tariffs, foreign exchange fluctuations, cybersecurity risks, evolving regulatory and compliance requirements, and data sovereignty changes, the Company’s ability to attract and retain key employees, changes in technology, including the impacts of artificial intelligence, automation, or other innovations that could alter competitive dynamics; and the risks and uncertainties described in the Company’s most recently filed Annual Information Form for the fiscal year ended June 30, 2025.
Forward-looking statements are based on the opinions, estimates, and assumptions of management as of the date of this press release and are inherently subject to significant business, economic, and competitive uncertainties and contingencies. Readers are cautioned not to place undue reliance on forward-looking statements, as there can be no assurance that the plans, intentions, or expectations upon which they are based will occur. Except as required by applicable securities laws, Sangoma undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
The forward-looking statements contained in this MD&A are expressly qualified by this cautionary statement. Sangoma undertakes no obligation to update forward-looking statements if circumstances or management’s estimates or opinions should change except as required by law.

OVERALL PERFORMANCE
Operational
Sangoma is a trusted leader in developing technology platforms for essential business communications. Customers include companies in the SMB, mid-market and enterprise spaces looking for all the advantages of cloud-based communications at a fair price. Sangoma offers a wide range of products to complement its services, delivering high-quality solutions through a global network of partners and distributors.
Sangoma has always been operated and managed as a single economic entity. There is one management team that directs the activities of all aspects of the Company and it is managed globally by our executive team. As a result, we believe that we have one reporting segment, being the consolidated Company. Over time, this may change as the Company grows and when this occurs, we will reflect the change in our reporting practice.
Revenue
Sangoma generates revenue from both Services and Products. Our Services revenue is generated primarily from customers entering recurring revenue agreements for services such as our UCaaS platforms and MSP services. Product revenues are comprised of the sale of products and services that generate non-recurring revenue, including our UC on-prem platform and hardware.
Beginning in Fiscal 2026, following the divestiture of Sangoma’s third-party hardware resale business, the Company will also provide supplemental revenue information in two categories: Core and Adjacent. Core services includes UCaaS, Switchvox, access, and MSP offerings, while Adjacent services comprises open source, connectivity, and TaaS solutions. This information provides an additional view of Sangoma’s revenue and growth drivers, highlighting the Company’s focus on expanding recurring revenue and increasing the proportion of total revenue derived from it.
Innovation
Sangoma is committed to advancing its AI capabilities by investing in and developing its proprietary AI platform and collaborating with leading third-party AI platforms.
By building on top of our existing CPaaS offerings and leveraging the low code/no code Studio workflow engine, we are delivering innovative Voice AI and Knowledge AI (RAG) Agent solutions that seamlessly integrate with our existing Cloud, Hybrid, and Prem products and services.
This approach ensures that our partners and customers benefit from both our in-house expertise and the broader AI ecosystem, enhancing their operations with cutting-edge, AI-driven services and insights.
Sales and marketing
Over the past year, Sangoma has undergone a transformation in its go-to-market strategy. We’ve embarked on a brand revitalization program with a strong focus on our digital properties, including new company positioning and refined messaging that reflects who we are as a company. We have established continuous education and training programs in collaboration with distributors and partners. Additionally, we have forged robust partnerships with key Technology Services Distributors (TSDs) like Telarus, Avant, App Direct, Intelisys, Jenne, and ScanSource to grow our business nationwide through the channel.
Sales
Sangoma utilizes a 100% channel-driven 'go to market' strategy, collaborating with diverse partners and market influencers. Our network includes individual agents, large technology service distributors (TSDs), and both national and regional distributors. Our customers span from mid-market enterprises needing distributed solutions to smaller SMBs that rely on our partners for digital infrastructure strategies.
Sangoma thrives in several sectors, notably healthcare, retail, and service providers. Through the Pinnacle Channel Partner Program, we offer extensive support to our partners, enabling them to deliver Sangoma's essential communication platform solutions to their end users. This support includes formal lead registration, training, quoting assistance, co-marketing efforts, and competitive commission structures and incentives.
Marketing
Sangoma's marketing goals are seamlessly aligned with its business objectives, which focus on driving revenue growth and delivering value to stakeholders. We also recognize the importance of increased brand visibility, recognition, and trust within the channel partner community and among end users.
Four key pillars anchor our marketing transformation: brand development and perception, channel marketing and enablement, lead generation, and fostering a culture of innovation and process efficiency.
For brand development, Sangoma has clarified its position as a leader in the communications industry, known for developing essential communication platforms with in-house software for all UC deployment types. This is complemented by offerings such as SIP trunking, hardware, managed services, and managed security.
Channel marketing and enablement are crucial for Sangoma, as we are dedicated to supporting our channel partners and distributors. Our multichannel strategy includes large and small events, webinars, trainings, online advertising, email marketing, public relations, promotional programs, and discounts.
In lead generation, our goal is to deliver more qualified leads to our partners, utilizing both outbound and inbound strategies. These are multichannel efforts targeting our Ideal Customer Profile with key messages about our solutions. Tactics include email, calls, content marketing, online advertising, social media, and public relations.
Lastly, cultivating a strong culture of trust and rapid experimentation, combined with robust CRM and email automation processes, is vital to our marketing transformation.

REVIEW OF OPERATIONS
As previously noted, following the divestiture of Sangoma’s third-party hardware resale business, VoIP Supply, LLC (“VS”), the Company is presenting its revenue in two categories: Core and Adjacent, as defined above. This new presentation provides a clearer view of Sangoma’s operations and growth drivers, highlighting the Company’s focus on expanding recurring revenue and increasing the proportion of total revenue derived from it.
To ensure consistent and meaningful comparisons, references to the new Core and Adjacent categories exclude VS from all historical periods. In contrast, the Company’s traditional revenue categories of Products and Services include VS, as the Company owned and operated VS for the entirety of Fiscal 2025. To facilitate comparability, Sangoma has also provided certain supplemental metrics—such as revenue, cost of sales, gross profit and margin, and Adjusted EBITDA—excluding VS, as further described within the MD&A.

Quarterly Comparison
Services revenue for the first quarter of Fiscal 2026 was $46,878 at 92% of total revenue, lower compared to $49,118 at 94% of total revenue in the equivalent quarter of the prior year, excluding VS, which the Company divested at the end of Fiscal 2025.

Quarterly Comparison
Core revenue for the first quarter of Fiscal 2026 was $37,596 representing 74% of total revenue compared to $40,032 or 76% of total revenue in the equivalent quarter of the prior year. The decline was primarily the result of longer sales cycles for larger deals.
Adjacent revenue for the first quarter of fiscal 2026 was $13,222, representing a 6% increase as compared to $12,482 in the equivalent quarter of the prior year. This increase is mainly the result of the Company’s TaaS offering, following a series of operational efficiencies that were implemented in the latter half of Fiscal 2025.
Total revenue for the first quarter of fiscal 2026 was $50,818, lower as compared to $52,514 of total revenue without VS revenue of $7,636 in the equivalent quarter of the prior year. On a quarter-over-quarter basis, Core revenue was lower compared to $38,788 in the fourth quarter of Fiscal 2025, while Adjacent revenue was higher compared to $13,081, excluding VS revenue of $7,636. Total revenue for the quarter was in line with the Company’s forecast and the Company expects to see sequential growth in its second fiscal quarter.

Sales and Net Loss by Quarter
As indicated in Fiscal 2025, the Company recently completed a comprehensive transformation of its go-to-market approach, which, while necessary for long-term scalability, contributed to extended sales cycles particularly for larger enterprise accounts and temporarily delayed revenue growth. With this foundational work now complete, the Company has shifted its focus to revenue generation and customer acquisition in Fiscal 2026, with sequential quarterly growth forecasted beginning in the second fiscal quarter. Services revenue continues to account for the majority of total revenue at 92% this quarter, while the Company did see an uptick in Product sales resulting from an increased attachment rate to its Services offerings. Operational efficiencies and cost-savings initiatives have helped maintain Adjusted EBITDA margin within a narrow range of 16-19% over the past eight quarters. The Company is beginning to realize the benefits of its revamped sales strategy, as reflected in early revenue indicators such as a growing pipeline.
LIQUIDITY AND CAPITAL RESOURCES
As at September 30, 2025, the Company had current assets of $42,708 and current liabilities of $49,052, compared with $42,622 and $49,476 at June 30, 2025, respectively. The increase in current assets is mainly due to trade and other receivables, while the decrease in current liabilities is primarily due to accounts payable and accrued liabilities.
Cash of $15,683 on September 30, 2025 was 16% higher than the $13,494 on June 30, 2025. The Company used a portion of its cash to continue servicing the debts. During the first quarter of Fiscal 2026, the Company repaid $5,150 in facility and loan payments compared to $8,725 in Fiscal 2025. As at September 30, 2025, the total outstanding debt was reduced to $42,750 from $69,100 as at September 30, 2024.
Trade receivables of $13,059 on September 30, 2025, were higher than the $10,631 on June 30, 2025, primarily due to the transition to the new payment processor which was a part of the ERP implementation. The Company has since seen trade receivables return to historical levels.
Inventories of $7,550 on September 30, 2025, were $677 lower than the $8,227 on June 30, 2025 due to the Company continuing to focus on selling existing inventories first while managing new purchases.
The Company’s net cash flows from operating activities in the first quarter of Fiscal 2026 was $4,938, lower than the $12,127 incurred in the same quarter of Fiscal 2025.
Net cash provided by operating activities as a percentage of Adjusted EBITDA for the first quarter of fiscal 2026 was 60% lower than 124% in the same quarter of fiscal 2025, primarily as a result of the increase in trade receivables resulting from the timing of the ERP implementation and the decrease in sales tax payable. To-date in the second quarter, the Company has seen trade receivables decrease to historical levels and the Company continues to anticipate quarterly net cash provided by operating activities as a percentage of Adjusted EBITDA in the range of 90-100%, further underscoring the improved operational efficiency and focus on long-term value creation.

CONTROLS AND PROCEDURES
Management of the Company, under the supervision of the Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining (i) disclosure controls and procedures, and (ii) adequate internal control over financial reporting (“ICFR”) (as defined under applicable Canadian securities laws and by the United States Securities and Exchange Commission (“SEC”) in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) for the company to ensure that (i) material information relating to the Company is made known to management by others, particularly during the period in which the annual and interim filings are being prepared; and (ii) information required to be disclosed by the Company in its annual and interim filings or other reports filed or submitted under securities legislation is recorded, processed, summarized and reported within the time period specified in securities legislation.
Management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer and oversight of the Board of Directors evaluated the effectiveness of our ICFR as of September 30, 2025 against the criteria set forth in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based upon the evaluation, management has concluded that the Company’s disclosure controls and procedures and ICFR were effective.
During the first quarter ended September 30, 2025, we continued to roll out our new ERP system in stages to improve the efficiency and consistency of our financial processes. As part of this rollout, we made related updates to certain ICFR. We are monitoring the transition closely and do not believe these changes have materially affected, or are reasonably likely to materially affect, our ICFR.
GLOSSARY OF TERMS
Analog
Analog telephony is the telephone system that dates back to the original experiments by Alexander Graham Bell. The voice signal is picked up by a microphone and transmitted to the central office. Voice signals from the central office consist of voltages that drive a headset to produce sound. Analog means that the voice pressure signals are represented by voltages levels on the line.
API
Application Program Interface: An API is a purpose-built interface that allows fourth party software to interact with a particular application. A typical API is the user interface for Windows that allows programmers to write programs for Windows that use all its built-in utilities. APIs do not depend on revealing source code, in general. They are usually well documented and include sample programs that make development easy.
Codec
In the telephony context a codec is a mechanism of digitally encoding voice. On the PSTN a voice channel takes up 64kbps in a codec standard called G.711. Cell phones use a codec called GSM that compresses the voice further so that a GSM call consumes about 24kbps. Other compressed codecs are used in VoIP to conserve bandwidth. These include standards such as G.729, G.723. Most audio codecs are lossy, in that some of the voice quality is degraded by the compression. On the other hand, as bandwidth becomes cheaper, VoIP allows one to use other codecs that in fact use more bandwidth than the PSTN, the so-called broadband codecs that have DVD-like voice quality.
Digital telephony
In the modern PSTN only the “last mile” line to the customer is still analog, all other internal parts of the network are digital. Digital in this case means that at the central office the analog signal from the subscriber’s telephone is sampled digitally, converting the line voltages to a series of numbers that can be easily transmitted error free over long distances. See T1, E1 below.
DID
Direct Inward Dialing (“DID”) is a virtual phone number that uses the existing phone lines to route incoming calls. Callers can connect to a phone extension directly without an operator. This offers convenience for both employees and callers alike. DID offers a cost saving on its own and is less expensive when purchased with a SIP trunk.
Gateway
In the telephony context this is typically a separate unit with its own case and power supply that provides VoIP-to-PSTN services for a VoIP network. Almost all gateway devices use SIP interfaces to the VoIP system over Ethernet and have analog or digital telephony interfaces that connect to the PSTN. VoIP gateways are available from many manufacturers including Audiocodes, Cisco, Grandstream, Patton Electronics and many others.
ISDN
Integrated Services Digital Network (“ISDN”) is a set of communications standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network. Of the many variations of ISDN, Sangoma supports BRI (Basic Rate Interface) which is essentially an all-digital replacement for ordinary analog lines and PRI (Primary Rate Interface) which is used over T1 and E1 lines. BRI is very popular outside of North America. PRI is used worldwide.
IoT
Internet of Things (“IoT”) refers to a system of interrelated, internet-connected objects that are able to collect and transfer data over a wireless network without human intervention.
IP
The Internet Protocol (“IP”) is the primary protocol in the internet layer of the Internet protocol suite, and delivers data packets from the source host to the destination host solely based on the IP address.
ISP
Internet Service Provider
ITSP
Internet Telephony Service Provider who offer telecommunications service including voice over internet type connections.
IVR
Interactive Voice Response: IVR systems use the phone to navigate a menu, for example those used by banks to allow access to customer’s account information. IVR systems have typically been driven by dial tones as the buttons on your phone are pressed, but increasingly they are using voice recognition for navigation.
Open Source
Open Source software is distributed free subject to certain conditions. Open Source licenses usually stipulate that source code must always be distributed or made available, and any improvements in the code have to be donated back to the community. It is possible to have dual licensing: Open Source to the community and also a closed, commercial license of the same or similar software.
NetBorder
This is the trade name of a Sangoma SIP to PSTN gateway product. It includes several other functions in addition to the PSTN gateway function. The mass marketed version is known as NetBorder Express or NBE.
PBX
Private branch exchange. A PBX is a premised basis device to deliver calls from the PSTN or VOIP network to phones in a single or multiple locations.
PSTN
Public Switched Telephone Network: This is the standard telephone network that has been in operation for many decades. A telephone or FAX or PBX or other telephony device is generally connected to an analog line at a wall plug, which is connected by “last mile” cabling to the central office. The analog signal from the device is converted to a digital signal at the Telco central office and is multiplexed, 24 simultaneous voice channels per line (in North America) onto a T1 for onward transmission. At the other end of the line the digital channel is reconverted to analog for transmission over the “last mile” to the receiving phone or other device.
SBC
A Session Border Controller (“SBC”) is a device deployed in Voice over Internet Protocol (“VoIP”) networks to exert control over the signaling and usually also the media streams involved in setting up, conducting, and tearing down telephone calls or other interactive media communications. SBCs are deployed as demarcation points between enterprises and service providers and between service provider networks.
SD-WAN
A Software-defined Wide Area Network (“SD-WAN”) uses software to control and manage connectivity across a customers wide area network. While traditional wide area networks rely on physical routers to connect remote users, this centralized software solution can help customers monitor their performance of the network and manage traffic.
Signaling
Call setup and tear down is remarkably complicated, involving such things as responding to the different tones as well as generating them, caller identification, and handling the different features like hook-flash and voicemail properly. There are different signaling mechanisms for different types of circuits. Analog circuits use tones such as out-of-order, busy, ringing as well as the dialing tones. T1 lines often use a data protocol called ISDN PRI, where packets of control data are exchanged on a separate data channel. ISDN PRI is a simplification of the general signaling protocol used internally by the telecommunications networks known as SS7. In all cases, signaling must be exactly compatible with what the Telco expects, so interoperability and standards are important.
SIP
Session Initiation Protocol: SIP is the emerging standard signaling protocol for VoIP, though it has much broader applications. SIP is responsible for setting up and teardown of two party and multiparty calls, as well as a host of management features. To a great and increasing extent, VoIP calls are SIP based. The term SIP Trunk is used to describe the provision of a SIP line to an end customer.
T1, E1
A T1 line is a circuit that simultaneously carries 24 digital telephone calls. At higher densities, 28 T1s are aggregated into a T3 line carrying 672 calls. Larger offices can also connect to the central office via T1 directly, so as to have only one circuit for up to 24 calls. T1 is standard in North America and Japan while E1 is the standard in the rest of the world. E1 carries 30 channels of digitized voice per line.
TDM
Time Division Multiplexing (“TDM”) is used in circuit switched networks to increase the number of calls carried simultaneously on any one circuit and formed the basis for the digital telephony networks.
TSD
A Technology Services Distributor (TSD) is a company that connects technology vendors and selling partners, and provides technology service solutions to IT sales agents. TSDs are also known as "master agents" or "telecom agents or brokers". TSDs play a key role in the technology advisory channel, and offer many benefits, including: quick access to solutions, generating sales volume, collecting commissions, industry experience and business solutions, enablement training, and marketing activities.
Unified Communications
Unified communications is a concept in which voice, email, messaging, video, and any other type of communication are all considered forms of data that can be combined, manipulated, and used in intelligent applications seamlessly.
VoIP
Voice over IP is the transfer of voice traffic over the Internet Protocol. IP is used universally for all networking, including local area networks and private networks, not just the Internet. VoIP is not necessarily voice over the Internet, but voice over general data networks.
