Corrections to the Prospectus

The Prospectus is hereby corrected and amended as follows (all amendments below in bold and italic text):

On the second cover page of the FSA-Prospectus, the following sentence is deleted under the heading "TÄRKEÄÄ TIETOA JA HUOMAUTUKSET SIJOITTAJILLE":

"Jos näissä on eroja, suomenkielinen Esite on ensisijainen."

In Element D.1 of the summary of the Eng-Prospectus, the following items are added (as risks specific to the Company and its industry):
"·  The Company may be adversely affected by fluctuations in exchange rates
  ·  The Company may be adversely affected by fluctuations in interest rates"

In Element E.1 of the summary of the Eng-Prospectus, the net proceeds of the Offering are corrected as follows:

"The Company expects to receive net proceeds from the issuance of the Offer Shares of approximately EUR 4.7 million, after deducting estimated offering expenses payable by the Company of approximately EUR 0.6 million, in the aggregate (of which a maximum of approximately EUR 0.1 million is paid as fee for underwriting commitment set forth in section E.3 below which is payable in cash and/or shares of the Company at the discretion of the Company)."

In Element E.6 of the summary of the Eng-Prospectus, the possible dilution effect of the directed share issue is corrected in the last paragraph as follows:

" If the Offering is subscribed in full and shares also issued in a separate directed issues as set forth above (see E.3 "Terms and conditions of the offer -  Directed issues of shares arranged in connection with the Offering) of the maximum amount of 1,665,575, the number of the Company's shares may rise after the Offering to (assuming full subscription of the Offering and  shares which may be subscribed with Offer Warrants) 73,247,987 shares. These shares issued in the directed share issues would correspond to approximately 51.2 per cent of all the Company's shares before the Offering (and such directed issued) and approximately 2.3 per cent of the Company's shares after the Offering, subscription of the shares based on the Offer Warrants and the directed issues, assuming that the Offering and shares issued in the directed issues are fully subscribed and all the Offer Warrants offered for the subscribers of Offer Shares are used for subscription of shares."

In Element B.9 of the Sw-Summary ("resultatprognos eller beräkning") numbering of the sub-paragraphs is corrected as follows:

(f) corrected to be (a)
(g) corrected to be (b)
(h) corrected to be (c)
(i) corrected to be (d)
(j) corrected to be (e)

In Element E.6 of the Sw-Summary, the possible dilution effect of the directed share issue is corrected in the last paragraph as follows:

" Om Erbjudandet blir fulltecknat och aktier även ges ut genom en riktad emission såsom beskrivs ovan (se E.3 "Villkor för erbjudandet - Riktade emissioner i samband med erbjudandet) inom maximigränsen på 1 665 575 aktier, kan antalet aktier i Bolaget öka från antalet aktier efter Erbjudandet (förutsatt att Erbjudandet fulltecknas och att alla Erbjudandewarranter som erbjuds till tecknarna utnyttjas för teckning av aktier) till 73 247 987 aktier. Dessa aktier som emitteras i de riktade emissionerna motsvarar cirka 51,2 procent av aktierna i Bolaget före Erbjudandet och cirka 2,3 procent av aktierna i Bolaget efter Erbjudandet, teckning av aktier med Erbjudandewarranterna och de riktade emissionerna, under antagande att Erbjudandet och de aktier som ges ut i de riktade emissionerna fulltecknas och att alla Erbjudandewarranter som tilldelas till tecknarna av Erbjudandeaktier utnyttjas för teckning av aktier."

On page 12 of the Eng-Prospectus, the following sentences are added in respect of the risk factor "Investors in the Sweden participating in the Offering may be adversely affected by fluctuations in foreign exchange rates":

"Nexstim's reporting currency is euro. However, the shares admitted to trading on First North Sweden, including the Offer Shares, will be traded and settled in Swedish crowns. Further, any potential future dividends will be denominated and distributed by the Company in euro. However, as regards to Shares held on book-entry accounts in the system of Euroclear Sweden, investors would receive the dividends in Swedish crowns after currency conversion from euro. Consequently, the market price of the Shares and the dividends received in Swedish crowns are affected by the changes in the exchange rate of the Swedish crown and euro. Therefore, as the Swedish crown is not fixed against the euro, any change in the exchange rate between the Swedish crown and euro could have an effect on revenues of the share investment of a shareholder. Value of dividends or other assets distributed in Swedish crown and value of shares denominated in First North Sweden in Swedish crowns may increase or decline as a result. This may have a material adverse effect on the market price of the Company's shares traded on First North Sweden and the future cash flows from dividends of the investors with Shares registered with Euroclear Sweden."

On page 21 of the Eng-Prospectus, the following correction is made in respect of expenses of the Offering under heading "REASONS FOR THE OFFERING AND USE OF PROCEEDS":

"The Company expects that the total proceeds of the Offering are at maximum EUR 5.2 million based on the maximum number of Offer Shares (45,552,444 Offer Shares) and the Subscription Price of EUR 0.115 per Offer Share. The Company expects to receive net proceeds from the issuance of the Offer Shares of approximately EUR 4.7 million, after deducting estimated offering expenses payable by the Company of approximately EUR 0.6 million, in the aggregate (of which a maximum of EUR 0.1 million is paid as fee for underwriting commitment set forth in "Arrangements related to the Offering - Underwriting commitments" of the Prospectus which fee is payable in cash and/or shares of the Company at the discretion of the Company)."

On page 33 of the Eng-Prospectus, the following correction is made under the heading "Underwriting commitments":

On page 61 of the Eng-Prospectus, the following correction is made to the number of the year under the heading "Organisation and employees":

"As of 31 December 2018, Nexstim employs 34 full-time employees (FTEs). The allocation of the employees between the group companies is presented in the following".

On page 74 of the Eng-Prospectus, the following correction is made to the number of the year in the last bullet point under the heading "RSU plan":

"  The Board of Directors resolved on 25 March 2019 to issue altogether 5,759 new shares without payment to four members of the Board of Directors. The members of the Board of Directors participating in the plan are Ken Charhut, Tomas Holmberg, Rohan Hoare and Juliet Thompson.
