(To Prospectus Supplements Dated August 30, 2024, December 10, 2024,

Shares of Common Stock
This prospectus supplement (this “Prospectus
Supplement”) amends and supplements the information in the prospectus, dated July 22, 2024 (the “Prospectus”), filed
with the Securities and Exchange Commission as a part of our registration statement on Form S-3 (File No. 333-280798) (the “Registration
Statement”), as previously supplemented by our prospectus supplements, dated August 30, 2024, December 10, 2024, October 10, 2025
and November 21, 2025 (such prospectus supplements together with the Prospectus, the “Prior Prospectus”), relating to the
offer and sale of shares of our common stock, $0.001 par value per share, pursuant to the terms of an At the Market Offering Agreement,
dated August 30, 2024 (the “Sales Agreement”) with Ladenburg Thalmann & Co. Inc (“Ladenburg”). This Prospectus
Supplement should be read in conjunction with the Prior Prospectus, and is qualified by reference thereto, except to the extent that the
information herein amends or supersedes the information contained in the Prior Prospectus. This Prospectus Supplement is not complete
without, and may only be delivered or utilized in connection with, the Prior Prospectus and any future amendments or supplements thereto.
We are filing this Prospectus Supplement to amend
the Prior Prospectus to increase the maximum amount of shares that we are eligible to sell under the Registration Statement pursuant to
the Sales Agreement under General Instruction I.B.6 of Form S-3. As a result of these limitations and the current public float of our
common stock, and in accordance with the terms of the Sales Agreement, we may offer and sell shares of our common stock having an aggregate
offering price of up to $2,125,000 from time to time through Ladenburg, which does not include the shares of common stock having an aggregate
sales price of approximately $7,245,131 that were sold pursuant to the Prior Prospectus to date. In the event that we may sell additional
amounts under the Sales Agreement in accordance with General Instruction I.B.6, we will file another prospectus supplement prior to making
such additional sales. This Prospectus Supplement amends and/or supplements only those sections of the Prior Prospectus as listed in this
Prospectus Supplement; all other sections of the Prior Prospectus remain as is.
As of April 10, 2026, the aggregate market value
of our outstanding common stock held by non-affiliates, or the public float, was approximately $25,732,336, which was calculated based
on 12,613,890 shares of common stock (including common stock issuable upon the exchange of exchangeable shares) outstanding as of April
10, 2026 held by non-affiliates at a price of $2.04 per share, the closing price of our common stock on the Nasdaq Capital Market on March
6, 2026. During the 12 calendar months prior to, and including, the date of this Prospectus Supplement, we sold securities with an aggregate
market value of approximately $6,452,424 pursuant to General Instruction I.B.6 of Form S-3. Pursuant to General Instruction I.B.6 of Form
S-3, in no event may we sell, pursuant to the Registration Statement of which this Prospectus Supplement and the Prior Prospectus are
a part, securities in a public primary offering with a value exceeding one-third of the aggregate market value of our public float in
any 12-month period, so long as our public float remains below $75,000,000.
Our common stock is traded on the Nasdaq Capital
Market under the symbol “PRSO.” On April 9, 2026, the last reported sale price of our common stock on the Nasdaq Capital Market
was $1.00 per share.
Investing in our common stock involves a high
degree of risk. Please read the information contained in and incorporated by reference under the heading “Risk Factors” beginning
on page S-8 of the prospectus supplement dated August 30, 2024, under the heading “Risk Factors” beginning on page 4 of the
Prospectus and the risk factors described in our most recent Annual Report on Form 10-K and in the documents that are incorporated by
reference into this Prospectus Supplement and the Prior Prospectus, and under similar headings in the other documents that are filed after
the date hereof and incorporated by reference into this Prospectus Supplement and the Prior Prospectus as they may be amended, updated
or modified periodically in our reports filed with the Securities and Exchange Commission.
Neither the Securities and Exchange Commission
nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the
accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Based on our preliminary internal financial reports,

We are currently in the process of finalizing
our condensed consolidated financial results for the quarterly period ended March 31, 2026 and, therefore, our actual results for this
period are not yet available. Our actual results may differ materially from the estimated preliminary results set forth above and will
not be finalized until after we complete our normal quarter-end financial accounting close process. Our preliminary results set forth
above reflect management’s best estimate of the impact of events during the quarter and are based on the information currently available
to us as of the date hereof.
Accordingly, undue reliance should not be placed
