Sangoma Announces CFO Transition: Larry Stock to Retire June 30; Adrian Back Named Interim CFO; Board Commences Search for Permanent Successor
Sangoma Technologies said CFO Larry Stock will retire effective June 30, 2026, after nearly six years, and will stay available for a one-year advisory role. From July 1, 2026, Adrian Back, currently Senior VP Finance, will become interim CFO. The board has started a search for a permanent successor, using internal and external candidates.
How this was made

The 30-second read
Why it matters
A planned CFO transition typically affects investor confidence in financial discipline and internal controls, especially if the permanent successor search later signals a change in strategy or accounting posture. Here, the company emphasizes balance-sheet strengthening and continuity through an internal interim CFO.
Market read
Near-term trading focus is on governance continuity and any implied changes in financial strategy ahead of the permanent CFO appointment.
What to watch
Watch for any subsequent disclosures tied to the permanent CFO search (timing, candidate profile, or changes to financial reporting/controls) that could emerge after the interim appointment.
Background
Sangoma is a communications platform provider offering UCaaS/CCaaS/CPaaS and related managed services; Adrian Back previously joined via the Star2Star acquisition and has led finance functions including audit, SOX compliance, and treasury.
Ticker impact
Sangoma announced CFO Larry Stock’s retirement effective June 30 and named Adrian Back interim CFO starting July 1.
Likely modest, two-sided reaction unless investors view the interim appointment as a signal of deeper strategic/financial change.
The article is a planned succession with continuity (internal finance leader) and no new financial targets or restatements; impact is mainly sentiment/positioning around governance continuity.
Market effects
Limited direct read-through to UCaaS/CPaaS peers; CFO transitions are company-specific unless tied to guidance or restructuring (not indicated here).
Primarily affects North American small/mid-cap communications software sentiment; no broader regional catalyst described.
Low global relevance; governance change at a single company without international regulatory or product shocks.
Counterpoint
Investors may discount the “continuity” narrative and instead worry the permanent successor search could reflect internal dissatisfaction or upcoming strategic pivots.
