About Polarean (www.polarean.com)

The Company and its wholly owned subsidiary, Polarean, Inc. (together the "Group") are revenue generating, medical drug-device combination companies operating in the high resolution medical imaging market.

The Group develops equipment that enables existing MRI systems to achieve an improved level of pulmonary function imaging and specialises in the use of hyperpolarised Xenon gas (129Xe) as an imaging agent to visualise ventilation and gas exchange regionally in the smallest airways of the lungs, the tissue barrier between the lung and the bloodstream and in the pulmonary vasculature. Xenon gas exhibits solubility and signal properties that enable it to be imaged within other tissues and organs.

The Group operates in an area of significant unmet medical need and the Group's technology provides a novel diagnostic approach, offering a non-invasive and radiation-free functional imaging platform which is more accurate and less harmful to the patient than current methods. The annual burden of pulmonary disease in the US is estimated to be over US$150 billion.

The Group also develops and manufactures high performance MRI radiofrequency (RF) coils which are a required component for imaging 129Xe in the MRI system. The development of these coils by the Group facilitates the adoption of the Xenon technology by providing application-specific RF coils which optimise the imaging of 129Xe in MRI equipment for use as a medical diagnostic as well as a method of monitoring the efficacy of therapeutic intervention.

Chairman's Statement

The transition from a private company to a publicly traded one is never easy. Being a public company requires an entirely different standard of performance in areas that are not usually considered key to the success of the business when it is privately held. It is a great credit to the leadership of any company if this transition is successfully accomplished with new shareholders and additional capital being brought into the picture. It is notable that Polarean (the "Group") has the distinction, at the time of writing, of being the only life-science IPO to be completed in London so far this year.

Polarean's technology solutions promise to bring critical new tools to physicians helping patients suffering from a wide range of pulmonary issues. The tools available today remain either limited in scope and accuracy or invasive and expensive. The unmet medical need is enormous. Fortunately, the steady advance of the state of the art in MRI technology, particularly faster data acquisition times, has enabled most scanners to acquire images, in detail and in 3D, in less than ten seconds. The widespread use of Magnetic Resonance Imaging ("MRI") systems in the US and Europe, makes available a very large installed base of scanners that can be used to implement Polarean's proprietary technology in a cost-effective manner, once it is approved for clinical use. The clinical trials to gain such approval are scheduled to start very soon and we expect them to be concluded within twelve months, following which the Company will need to prepare the New Drug Application (NDA) for submission to the FDA. The protocol for the trials has been set in collaboration with the FDA and Polarean and its clinical and scientific advisors believe the non-inferiority margins agreed with the FDA are achievable with the trial size and timeframe indicated. We continue to expect to launch clinically approved systems in early 2020.

Polarean's technology has been in development for almost 20 years and the Group's systems are already in use by researchers at over a dozen leading academic and medical institutions in the United States and Europe. One of these is the Cincinnati Children's Hospital where the team is working closely with Polarean, with funding from a grant provided by the Small Business Innovation Research Program, to develop applications in cystic fibrosis. Cystic fibrosis is one of the most debilitating conditions, especially in children and is particularly hard to diagnose, monitor and manage. This network of key opinion leaders who are working closely with the Group, creates an expanding group of knowledgeable experts who will be crucial in effecting broad adoption of the clinically approved technology by leading medical institutions in the US and elsewhere.

The team at Duke University, led by one of Polarean's founders, Professor Bastiaan Driehuys, is actively advancing the state of the art with new developments in critical areas such as gas exchange. These developments promise to facilitate the application of the technology in a range of additional conditions beyond ventilation, such as pulmonary fibrosis and pulmonary vascular disease, two diseases of increasing prevalence for which current diagnostic methods are very invasive and not very effective.

We believe Polarean has immense promise and the fact that it has reached this critical juncture is a great credit to the team in North Carolina who have brought it this far. The road ahead will no doubt present challenges but we face that journey with determination and high confidence in the strength of the technology and the commitment of the team.

Chief Executive Officer's Statement

2017- A Year of Preparation and Accomplishment

The Group was formed on 31 May 2017 when Polarean Imaging Plc (the "Company" or "Parent Company") Company acquired Polarean, Inc (the "Subsidiary") and spent the remainder of the year working towards the Company's listing on AIM, which was successfully completed in the first quarter of 2018.

We were also busy making arrangements for our Phase III Clinical Trials and we achieved several critical milestones in research and development ("R&D") and manufacturing in support of those trials, including:

• engaging contract research organizations ("CROs") specializing in medical imaging non-inferiority trials like ours at the institutions where we are conducting the trials and then continuing to develop the plans for the trials in conjunction with those selected CROs;
• entering into contracts with the trial sites;
• preparing our quality systems and product documentation in order to outsource production to a local professional manufacturer who is already GMP-certified;
• continuing to develop and protect important intellectual property, adding to our dominant patent position; and
• identifying, evaluating and selecting a candidate, Linde who are one of the largest global industrial gas suppliers, and entering into agreements to package and distribute our proprietary 129Xe drug, in preparation for the Phase III clinical trials. We are fortunate to have Nukem Isotopes GmbH as a strategic investor and supplier of our enriched 129Xe raw material and we thank them for their support.

In addition, in late 2017 our R&D group significantly improved the performance of our polariser product, which has resulted in better images and has potentially reduced the amount of xenon required to be inhaled by the patient to make the images, thereby improving patient acceptance as well as our product economics, which your Directors and your clinical team consider to be a tremendous accomplishment.

The Opportunity

The US Healthcare annual burden of pulmonary disease is US$150 billion and your Directors see a tremendous opportunity to bring our technology's quantitative, reproducible, non-invasive method for diagnostic and therapeutic guidance to medicine. We believe it will benefit patients, improve outcomes and reduce costs. This is important as the current cumulative global costs of asthma, COPD, emphysema, cystic fibrosis, idiopathic pulmonary fibrosis, interstitial lung disease, and pulmonary vascular disease are huge.

While working to achieve FDA approval for clinical use, Polarean continues to serve the medical imaging research market by providing xenon polarizers to enable functional MRI of the pulmonary system. This brings dynamic, high-resolution, regional, image based information to pulmonary physicians whose best alternative tool is spirometry, a relatively inaccurate measurement of expired breath. Current imaging technologies are not often used for assessing lung function, despite the revolutionary effects of MRI in other medical applications.

Our Clinical Trial

Our Phase III Clinical Trial is a head-to-head, non-inferiority trial which is comparing our technology to the 40 year old nuclear medicine technique using radioactive 133Xe and gamma cameras. The trial involves 80 patients in total, and will be conducted at two of our closest collaborative sites, the University of Virginia and Duke University. We are characterising ventilation in two sets of patients being evaluated for surgical procedures: those who are being evaluated for lung lobar resection surgery and those being evaluated for lung transplant. In each case their pre-operative expired vital capacity is measured through spirometry. Our technology and the existing nuclear medicine standard of care are used to assess the remaining post-operative vital capacities. Our trial focuses entirely on the pre-operative assessment and it makes no difference whether the patient is chosen for surgery or not. We have to allow for an equivalence margin in order to be non-inferior. We expect the trial to proceed as planned to a successful outcome and anticipate the trial to result, in due course, in the Group receiving FDA approval to commercialise the product and process.

2017 Financial Results

We encountered difficult market conditions when looking to quote the Company but we were pleased to raise £3 million (before expenses), in addition to the £0.7 million that was raised in December 2017 via the issue of convertible loan notes, in order to fund the clinical trial. In this phase of our development, with sales to academic institutions that are acquiring the technology predominantly by way of grant funding, our forecasting of revenue and price is typically on target but there are challenges in estimating the timing of the receipt of orders. We partly mitigate this by way of payment terms that include significant deposits, minimizing working capital timing effects. Operationally, our performance has been as expected, with revenue of US$1.24 million and operating gross margins at over 50%.

2018 and Beyond

In 2018, we look forward to commencing our clinical trial and the continued expansion of our installed base of systems through additional sales of research units to academic institutions. Our R&D focus has shifted slightly and is now mainly looking at the imaging of gas exchange and the regional assessment of lung tissue function, beyond ventilation, led by our founder and Chief Technology Officer, Dr. Bastiaan Driehuys at Duke University. The Directors have seen tremendous interest in pulmonary vascular disease as an emerging application, which is good news for the Group looking towards the future.

Polarean is fortunate to have an outstanding collection of world-class collaborators and customers in both the US and Europe. Additionally, we support the "129Xe MRI Clinical Trials Consortium" and the crucial work they do in collaborative research, training investigators, providing infrastructure for evaluating new techniques, and multi-institution sharing of magnetic resonance (MR) techniques and image analysis methods. We would like to thank the National Heart Lung and Blood Institute for their continued support of our Small Business Innovation Research Program grant with Cincinnati Children's Hospital Medical Center. In addition, we have developed solid working relationships with MRI systems manufacturers and exclusive relationships with global industrial gas suppliers, all key to our future as we scale the business.

On behalf of the entire staff of Polarean Imaging Plc, I would like to thank you for your investment in and support of the Group and we look forward to continuing to develop and deliver this critical life-saving and life-improving technology to physicians and patients everywhere.

Polarean's technology has been in development for almost 20 years and the Group's systems are already in use by researchers at over a dozen leading academic and medical institutions in the United States and Europe. One of these is the Cincinnati Children's Hospital where the team is working closely with Polarean, with funding from a grant provided by the Small Business Innovation Research Program, to develop applications in cystic fibrosis. Cystic fibrosis is one of the most debilitating conditions, especially in children and is particularly hard to diagnose, monitor and manage. This network of key opinion leaders who are working closely with the Group, creates an expanding group of knowledgeable experts who will be crucial in effecting broad adoption of the clinically approved technology by leading medical institutions in the US and elsewhere.

The team at Duke University, led by one of Polarean's founders, Professor Bastiaan Driehuys, is actively advancing the state of the art with new developments in critical areas such as gas exchange. These developments promise to facilitate the application of the technology in a range of additional conditions beyond ventilation, such as pulmonary fibrosis and pulmonary vascular disease, two diseases of increasing prevalence for which current diagnostic methods are very invasive and not very effective.

We believe Polarean has immense promise and the fact that it has reached this critical juncture is a great credit to the team in North Carolina who have brought it this far. The road ahead will no doubt present challenges but we face that journey with determination and high confidence in the strength of the technology and the commitment of the team.

Chief Executive Officer's Statement

2017- A Year of Preparation and Accomplishment

The Group was formed on 31 May 2017 when Polarean Imaging Plc (the "Company" or "Parent Company") Company acquired Polarean, Inc (the "Subsidiary") and spent the remainder of the year working towards the Company's listing on AIM, which was successfully completed in the first quarter of 2018.

We were also busy making arrangements for our Phase III Clinical Trials and we achieved several critical milestones in research and development ("R&D") and manufacturing in support of those trials, including:

• engaging contract research organizations ("CROs") specializing in medical imaging non-inferiority trials like ours at the institutions where we are conducting the trials and then continuing to develop the plans for the trials in conjunction with those selected CROs;
• entering into contracts with the trial sites;
• preparing our quality systems and product documentation in order to outsource production to a local professional manufacturer who is already GMP-certified;
• continuing to develop and protect important intellectual property, adding to our dominant patent position; and
• identifying, evaluating and selecting a candidate, Linde who are one of the largest global industrial gas suppliers, and entering into agreements to package and distribute our proprietary 129Xe drug, in preparation for the Phase III clinical trials. We are fortunate to have Nukem Isotopes GmbH as a strategic investor and supplier of our enriched 129Xe raw material and we thank them for their support.

In addition, in late 2017 our R&D group significantly improved the performance of our polariser product, which has resulted in better images and has potentially reduced the amount of xenon required to be inhaled by the patient to make the images, thereby improving patient acceptance as well as our product economics, which your Directors and your clinical team consider to be a tremendous accomplishment.

The Opportunity

The US Healthcare annual burden of pulmonary disease is US$150 billion and your Directors see a tremendous opportunity to bring our technology's quantitative, reproducible, non-invasive method for diagnostic and therapeutic guidance to medicine. We believe it will benefit patients, improve outcomes and reduce costs. This is important as the current cumulative global costs of asthma, COPD, emphysema, cystic fibrosis, idiopathic pulmonary fibrosis, interstitial lung disease, and pulmonary vascular disease are huge.

While working to achieve FDA approval for clinical use, Polarean continues to serve the medical imaging research market by providing xenon polarizers to enable functional MRI of the pulmonary system. This brings dynamic, high-resolution, regional, image based information to pulmonary physicians whose best alternative tool is spirometry, a relatively inaccurate measurement of expired breath. Current imaging technologies are not often used for assessing lung function, despite the revolutionary effects of MRI in other medical applications.

Our Clinical Trial

Our Phase III Clinical Trial is a head-to-head, non-inferiority trial which is comparing our technology to the 40 year old nuclear medicine technique using radioactive 133Xe and gamma cameras. The trial involves 80 patients in total, and will be conducted at two of our closest collaborative sites, the University of Virginia and Duke University. We are characterising ventilation in two sets of patients being evaluated for surgical procedures: those who are being evaluated for lung lobar resection surgery and those being evaluated for lung transplant. In each case their pre-operative expired vital capacity is measured through spirometry. Our technology and the existing nuclear medicine standard of care are used to assess the remaining post-operative vital capacities. Our trial focuses entirely on the pre-operative assessment and it makes no difference whether the patient is chosen for surgery or not. We have to allow for an equivalence margin in order to be non-inferior. We expect the trial to proceed as planned to a successful outcome and anticipate the trial to result, in due course, in the Group receiving FDA approval to commercialise the product and process.

2017 Financial Results

We encountered difficult market conditions when looking to quote the Company but we were pleased to raise £3 million (before expenses), in addition to the £0.7 million that was raised in December 2017 via the issue of convertible loan notes, in order to fund the clinical trial. In this phase of our development, with sales to academic institutions that are acquiring the technology predominantly by way of grant funding, our forecasting of revenue and price is typically on target but there are challenges in estimating the timing of the receipt of orders. We partly mitigate this by way of payment terms that include significant deposits, minimizing working capital timing effects. Operationally, our performance has been as expected, with revenue of US$1.24 million and operating gross margins at over 50%.

2018 and Beyond

In 2018, we look forward to commencing our clinical trial and the continued expansion of our installed base of systems through additional sales of research units to academic institutions. Our R&D focus has shifted slightly and is now mainly looking at the imaging of gas exchange and the regional assessment of lung tissue function, beyond ventilation, led by our founder and Chief Technology Officer, Dr. Bastiaan Driehuys at Duke University. The Directors have seen tremendous interest in pulmonary vascular disease as an emerging application, which is good news for the Group looking towards the future.

Polarean is fortunate to have an outstanding collection of world-class collaborators and customers in both the US and Europe. Additionally, we support the "129Xe MRI Clinical Trials Consortium" and the crucial work they do in collaborative research, training investigators, providing infrastructure for evaluating new techniques, and multi-institution sharing of magnetic resonance (MR) techniques and image analysis methods. We would like to thank the National Heart Lung and Blood Institute for their continued support of our Small Business Innovation Research Program grant with Cincinnati Children's Hospital Medical Center. In addition, we have developed solid working relationships with MRI systems manufacturers and exclusive relationships with global industrial gas suppliers, all key to our future as we scale the business.

On behalf of the entire staff of Polarean Imaging Plc, I would like to thank you for your investment in and support of the Group and we look forward to continuing to develop and deliver this critical life-saving and life-improving technology to physicians and patients everywhere.

About Polarean (www.polarean.com)

The Company and its wholly owned subsidiary, Polarean, Inc. (together the "Group") are revenue generating, medical drug-device combination companies operating in the high resolution medical imaging market.

The Group develops equipment that enables existing MRI systems to achieve an improved level of pulmonary function imaging and specialises in the use of hyperpolarised Xenon gas (129Xe) as an imaging agent to visualise ventilation and gas exchange regionally in the smallest airways of the lungs, the tissue barrier between the lung and the bloodstream and in the pulmonary vasculature. Xenon gas exhibits solubility and signal properties that enable it to be imaged within other tissues and organs.

The Group operates in an area of significant unmet medical need and the Group's technology provides a novel diagnostic approach, offering a non-invasive and radiation-free functional imaging platform which is more accurate and less harmful to the patient than current methods. The annual burden of pulmonary disease in the US is estimated to be over US$150 billion.

The Group also develops and manufactures high performance MRI radiofrequency (RF) coils which are a required component for imaging 129Xe in the MRI system. The development of these coils by the Group facilitates the adoption of the Xenon technology by providing application-specific RF coils which optimise the imaging of 129Xe in MRI equipment for use as a medical diagnostic as well as a method of monitoring the efficacy of therapeutic intervention.

Chairman's Statement

The transition from a private company to a publicly traded one is never easy. Being a public company requires an entirely different standard of performance in areas that are not usually considered key to the success of the business when it is privately held. It is a great credit to the leadership of any company if this transition is successfully accomplished with new shareholders and additional capital being brought into the picture. It is notable that Polarean (the "Group") has the distinction, at the time of writing, of being the only life-science IPO to be completed in London so far this year.

Polarean's technology solutions promise to bring critical new tools to physicians helping patients suffering from a wide range of pulmonary issues. The tools available today remain either limited in scope and accuracy or invasive and expensive. The unmet medical need is enormous. Fortunately, the steady advance of the state of the art in MRI technology, particularly faster data acquisition times, has enabled most scanners to acquire images, in detail and in 3D, in less than ten seconds. The widespread use of Magnetic Resonance Imaging ("MRI") systems in the US and Europe, makes available a very large installed base of scanners that can be used to implement Polarean's proprietary technology in a cost-effective manner, once it is approved for clinical use. The clinical trials to gain such approval are scheduled to start very soon and we expect them to be concluded within twelve months, following which the Company will need to prepare the New Drug Application (NDA) for submission to the FDA. The protocol for the trials has been set in collaboration with the FDA and Polarean and its clinical and scientific advisors believe the non-inferiority margins agreed with the FDA are achievable with the trial size and timeframe indicated. We continue to expect to launch clinically approved systems in early 2020.

Polarean's technology has been in development for almost 20 years and the Group's systems are already in use by researchers at over a dozen leading academic and medical institutions in the United States and Europe. One of these is the Cincinnati Children's Hospital where the team is working closely with Polarean, with funding from a grant provided by the Small Business Innovation Research Program, to develop applications in cystic fibrosis. Cystic fibrosis is one of the most debilitating conditions, especially in children and is particularly hard to diagnose, monitor and manage. This network of key opinion leaders who are working closely with the Group, creates an expanding group of knowledgeable experts who will be crucial in effecting broad adoption of the clinically approved technology by leading medical institutions in the US and elsewhere.

These developments promise to facilitate the application of the technology in a range of additional conditions beyond ventilation, such as pulmonary fibrosis and pulmonary vascular disease, two diseases of increasing prevalence for which current diagnostic methods are very invasive and not very effective.

We believe Polarean has immense promise and the fact that it has reached this critical juncture is a great credit to the team in North Carolina who have brought it this far. The road ahead will no doubt present challenges but we face that journey with determination and high confidence in the strength of the technology and the commitment of the team.

We encountered difficult market conditions when looking to quote the Company but we were pleased to raise £3 million (before expenses), in addition to the £0.7 million that was raised in December 2017 via the issue of convertible loan notes, in order to fund the clinical trial. In this phase of our development, with sales to academic institutions that are acquiring the technology predominantly by way of grant funding, our forecasting of revenue and price is typically on target but there are challenges in estimating the timing of the receipt of orders. We partly mitigate this by way of payment terms that include significant deposits, minimizing working capital timing effects. Operationally, our performance has been as expected, with revenue of US$1.24 million and operating gross margins at over 50%.

2018 and Beyond

In 2018, we look forward to commencing our clinical trial and the continued expansion of our installed base of systems through additional sales of research units to academic institutions. Our R&D focus has shifted slightly and is now mainly looking at the imaging of gas exchange and the regional assessment of lung tissue function, beyond ventilation, led by our founder and Chief Technology Officer, Dr. Bastiaan Driehuys at Duke University. The Directors have seen tremendous interest in pulmonary vascular disease as an emerging application, which is good news for the Group looking towards the future.

Polarean is fortunate to have an outstanding collection of world-class collaborators and customers in both the US and Europe. Additionally, we support the "129Xe MRI Clinical Trials Consortium" and the crucial work they do in collaborative research, training investigators, providing infrastructure for evaluating new techniques, and multi-institution sharing of magnetic resonance (MR) techniques and image analysis methods. We would like to thank the National Heart Lung and Blood Institute for their continued support of our Small Business Innovation Research Program grant with Cincinnati Children's Hospital Medical Center. In addition, we have developed solid working relationships with MRI systems manufacturers and exclusive relationships with global industrial gas suppliers, all key to our future as we scale the business.

On behalf of the entire staff of Polarean Imaging Plc, I would like to thank you for your investment in and support of the Group and we look forward to continuing to develop and deliver this critical life-saving and life-improving technology to physicians and patients everywhere.
