One filer, two names: every record resolves to Byrna Technologies Inc., renamed from Security Devices International Inc. effective March 4, 2020

Asked:

“Give me evidence of byrna entity resolution”

15 selected evidence records from two independent official hosts — 6 from sec.gov and 9 from ir.byrna.com — spanning filings from July 2019 to February 2026, assembled on 2026-10-07. The set is an evidentiary sample, not every Byrna filing. Each record carries verbatim quotations tying the names “Byrna,” “Byrna Technologies,” “SDI,” “SDEV,” and “SDZ” to one legal entity: Byrna Technologies Inc. (SEC CIK 1354866; EIN 71-1050654 found in extracted current-filing evidence).

Strongest direct statements

Form 8-K, the controlling rename statement

“On March 4, 2020, Security Devices International Inc. (the ‘Company’) changed its name to ‘Byrna Technologies Inc.’ … accomplished pursuant to a Certificate of Amendment … filed with the Secretary of State of Delaware on February 26, 2020.”

sec.gov

Ticker continuity, same 8-K

“The Company's common stock continues to trade on the Canadian Securities Exchange and the OTCQB under Byrna Technologies Inc. and the new stock symbol is ‘BYRN.’”

Current 10-K, corporate history restated

“We were incorporated in Delaware on March 1, 2005 under the name Security Devices International Inc. On February 26, 2020, we filed an amendment to our Certificate of Incorporation … changing our name, effective March 4, 2020, to Byrna Technologies Inc.”

What the trail establishes

Resolve “Byrna” and “Byrna Technologies” to the legal entity Byrna Technologies Inc.: proxy and 8-K filings define “Byrna” as the Company itself — sec.gov

Resolve “SDI,” ticker SDEV (OTCQB) and SDZ (CSE) as historical aliases of the same filer, not a separate company: SDI announced the Byrna HD and the coming name and ticker change — ir.byrna.com

BYRN later moved to the Nasdaq Capital Market, where current 10-K filings register the common stock — ir.byrna.com

Keep brand and product references distinct: “Byrna®” is a registered trademark and “Byrna HD” a product of the entity — a product mention alone never merges into the corporate record — sec.gov

Data-quality note: three 2022 SEC text-file headers read “DATE OF NAME CHANGE: 20060301” — an EDGAR historical-header anomaly, not the operative Byrna rename; the direct 8-K controls the date of 2020-03-04 — sec.gov

Method: 15 selected evidence records about the Byrna / Security Devices International entity resolution, drawn from two independent official hosts (sec.gov, ir.byrna.com), assembled 2026-10-07. Each row pairs a filing with verbatim quotations on legal name, former name, alias, ticker and rename date; dates are the event or filing dates stated in the documents. Long quotations are trimmed to one representative sentence for space; the linked source holds the full text. The 2006-03-01 dates in some EDGAR headers are a historical-header anomaly, not the operative rename date (2020-03-04). The set is a sample, not a complete filing index.
