Financial Overview $25.6M cash and no outstanding debt as of December 31, 2018 November 2018: Completed registered public offering with net proceeds of $18.3M at price of $8.25, led by BTIG and Oppenheimer Full Year 2018 Summary: Reported First Company Revenue: $0.5M, licensing fee for Canadian rights granted to Heuro Operating Expenses: $27.2 million in 2018 vs. $22.9 million in 2017 increase of $4.3M Year-over-year increase driven primarily by an increase of $8.7 million in G&A expenses due primarily to higher stock-based compensation expense, which was primarily the result of the change in the Company’s functional currency* Year-over-year increase offset partially by a decrease of $4.4 million in research and development expenses, primarily due to reduced clinical trial and product development expenses Total Other Expense: $1.9M in 2018 vs. $5.2M in 2017, a decrease of $3.2M Year-over-year decrease driven primarily by a foreign exchange gain of $1.6M in 2018 versus a foreign exchange loss of $1.7M in 2017 Net Loss: $28.6M in 2018 vs. $28.0M in 2017 Net Cash Used in Operating Activities: $19.6M in 2018 vs. $19.3M in 2017 Net Cash Provided by Financing Activities: $40.0M in 2018 vs.$22.2M in 2017. www.heliusmedical.com | NASDAQ:HSDT | TSX:HSM *Note: Changed functional currency from $CAD to $USD, effective April 1, 2018. Financial statements prior to and including the period ending March 31, 2018 have not been restated for the change in functional currency.

Full Year 2019 Outlook www.heliusmedical.com | NASDAQ:HSDT | TSX:HSM 2019 Guidance: For 2019, we expect total revenue in a range of $1.6 million to $2.0 million U.S. dollars.   Assumptions Supporting 2019 Guidance: 2019 revenue guidance assumes an exchange rate of $1 Canadian dollar to $0.75 US dollars. We expect all revenue will be generated only from contributions by the two founding neuroplasticity clinics that are operational and treating patients in Canada. We anticipate generating revenue of approximately $18,000 Canadian dollars per device delivered to the Canadian clinics in 2019. We expect to engage three additional neuroplasticity clinics in Canada during the course of the year, one in each of the last 3 quarters of the year, to end 2019 with a total of 5 clinics.

Tongue Based Neuromodulation The PoNS® investigational medical device gently stimulates the trigeminal nerve through the tongue to activate neuroplasticity in the brain and unlock its ability to restore lost function. Tongue Based Neuromodulation The nerves in the tongue are directly connected to the brainstem, which is the body’s control center. It is dense with nerve endings in a warm, dark environment making it ideal for stimulation A mild-to- moderate TBI damages a part of the brain, reducing the ability of the brain’s neural impulses to communicate clearly with the body To restore balance and function, the brain needs to be “rewired” to work around the damaged area and reestablish neural impulses to the body. This “rewiring” is called neuroplasticity. We achieve this change by neuromodulation.     www.heliusmedical.com | NASDAQ:HSDT | TSX:HSM

PoNS® Registrational Trial in TBI Important Criteria For the Study 120 subjects Response criteria was set at 15 point improvement in Sensory Organization Test (SOT), an objective measure used in balance research 15 point SOT score improvement is 50% higher than the expectation in the medical literature for physical therapy alone. All subjects had to: Have participated in a focused physical rehabilitation program and have reached a plateau Still have significant balance issues as they entered the study All subjects were at least one year post-injury Further spontaneous recovery unlikely 71.6% of 120 subjects in trial were responders PoNS® Registrational Trial in TBI Were responders 53.7% Were in the Normal Range for Balance www.heliusmedical.com | NASDAQ:HSDT | TSX:HSM
