KELOWNA, BC / ACCESS Newswire / July 6, 2026 / Lexaria Bioscience Corp. (NASDAQ:LEXX) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, is pleased to have experienced many positive meetings with potential pharmaceutical partners and collaborators at the 2026 BIO International Convention ("BIO") in San Diego, CA.

"Lexaria had a full schedule at BIO, meeting with a diverse group of companies ranging from innovative smaller tech-focused firms to multi-billion-dollar global pharmaceutical companies," said Richard Christopher, CEO of Lexaria Bioscience Corp. "We are balancing new exploratory corporate opportunities with existing corporate relationships, with the intent of entering into partnership arrangements. Not a week goes by without discussion with one or more potential partners."

While new corporate relationships require time to identify areas of common interest and capabilities, including but not limited to technologic compatibility, we also continue to advance our pre-existing corporate relationships. While timelines and closure rates are impossible to predict, Lexaria remains optimistic about its prospects.

Of note, most of Lexaria's business discussions are related to the GLP-1 sector and its many applications. Within the GLP-1 sector, Lexaria detected a notable shift in this year's BIO conference to a focus on drug safety and adverse event profiles, given the reality that certain drugs currently under development are approaching practical maximums of weight-loss efficacy. Both in public presentations as well as in our one-on-one meetings, a growing number of pharmaceutical companies are confirming that their focus has shifted towards finding a better balance between weight-loss efficacy, tolerability and safety. The idea that GLP-1 drugs can work effectively at the same time as minimizing unpleasant adverse events is consistent with both Lexaria's mission, and the capabilities of our DehydraTECH^TM technology.

In addition, Lexaria is pleased to report that interest in DehydraTECH technology is expanding once again outside of the GLP-1 industry. Lexaria has recently received renewed incoming corporate interest in the DehydraTECH-CBD and DehydraTECH-nicotine sectors where the Company has conducted extensive previous R&D validating the efficacy of the DehydraTECH technology.

Additional business development information will be made available as appropriate.

KELOWNA, BC / ACCESS Newswire / June 25, 2026 / Lexaria Bioscience Corp. (NASDAQ:LEXX) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, announces that dosing began on schedule on June 14^th with Human Pilot Study #7 (GLP-1-H26-7) that is evaluating two oral DehydraTECH-semaglutide ("DHT-sema") compositions against Novo Nordisk's® ("Novo") commercially available Wegovy® tablets, over a 5-week duration (the "Study").

Lexaria is seeking to preserve the superior safety and tolerability profiles evidenced in its previous glucagon-like peptide-1 ("GLP-1") studies such as Human Study #4 (GLP-1-H24-4), combined with pharmacokinetic ("PK") performance that matches or exceeds the Wegovy® tablet control. Previous Lexaria salcaprozate sodium ("SNAC")-inclusive DHT-sema single dose studies such as Human Pilot Studies #1 and #2 (GLP-1-H24-1 and GLP-1-H24-2) evidenced PK performance that matched or exceeded the Rybelsus® control arm and also evidenced noteworthy safety and tolerability profiles.

The results of this Study are expected to be carefully reviewed by the pharmaceutical industry in order to evaluate the possibility of entering into commercial relationships focused on Lexaria's proprietary DehydraTECH™ technology.

The Study is investigating three separate arms to assess safety & tolerability as well as PK properties that will compare SNAC-inclusive, DHT-sema compositions formulated in both tablet and capsule formats to commercially available Wegovy® tablets. The Study is being conducted under fasted pre-dose conditions similar to the advised administration criteria of Novo's oral semaglutide products. The 5-week dosing duration was selected in order to allow for achievement of steady state concentration levels, meaning that the semaglutide blood quantities in each arm will be expected to reach an equilibrium level that balances drug input with natural bodily elimination.

The Study is exploring several new DehydraTECH™ enhancements not previously evaluated, which include but are not limited to the following two main improvements:

(1) First, an oral tablet DHT-sema composition will be used by Lexaria for the first time, as opposed to only the capsule compositions administered in all our previous DehydraTECH™ GLP-1 studies. Novo's Rybelsus® and Wegovy® oral semaglutide medications use specially formulated tablets designed to temporarily adhere to the stomach lining and disintegrate and dissolve releasing agents in a focal manner that aids in optimizing absorption of semaglutide into the human body. For the first time ever, Lexaria has attempted to mimic and integrate certain physical properties of the Rybelsus® and Wegovy® SNAC-inclusive tablet delivery modality into its DHT-sema tablets to follow established industry standards and thereby increase the likelihood of subsequent commercial pharmaceutical relationships.

(2) Second, both the Lexaria DHT-sema tablet and capsule test articles will be formulated with SNAC, which will be the first time these formulations will be evaluated over a multi-dose, multi-week time period in humans. The five-week dosing duration of the Study is expected to be long enough to reach so-called steady-state, which is when drug concentrations in the body reach a constant concentration. As noted above, Human Pilot Studies #1 and #2 (GLP-1-H24-1 and GLP-1-H24-2), conducted in 2024 and 2025 which incorporated SNAC (but did not use tablets), were limited by single-dose study designs and therefore of much shorter duration.

The Study is fully funded from existing corporate resources.

Potentially Valuable Novel Compositions Being Investigated

Lexaria Also Receives Additional New Granted Patent

KELOWNA, BC / ACCESS Newswire / June 23, 2026 / Lexaria Bioscience Corp. (NASDAQ:LEXX) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms, provides the following update on Animal Study #1 (GLP-1-A26-1) that is evaluating a number of formulation enhancements using both DehydraTECH-semaglutide ("DHT-sema") glucagon-like peptide-1 ("GLP-1") compositions and DehydraTECH-CBD ("DHT-CBD") compositions to explore the potential for additional improved performance as well as stake new intellectual property ("IP") claims (the "Study").

The Study is on schedule and dosing began on June 10, 2026, as planned. Barring any unforeseen interruptions, Study results are currently expected by early September.

One of the novel objectives of this Study is to evaluate innovative alternative formulations to SNAC (salcaprozate sodium) which is currently in use by Novo Nordisk® with their oral Rybelsus® and Wegovy® tablet products. If Lexaria is able to scientifically evidence novel new formulations with similarity or superiority to SNAC performance enhancements, we may be able to establish valuable new proprietary IP and an industry alternative to SNAC that could be of value within the keenly competitive GLP-1 sector. To this end, Lexaria is pleased to report that we have already filed 3 new patent applications that anticipate our latest technological improvements in this area.

The Study is utilizing Sprague-Dawley rats with 11 separate Study arms evaluating a number of different novel compositions. Blood samples are being taken at multiple timepoints through an 8-24 hour post-dosing period to quantify the pharmacokinetic performance of each composition. In addition, the Study will also measure drug concentrations in the brain since DehydraTECH has, in the past, evidenced apparent superior absorption of active ingredients into brain tissue, an area of intense interest due to the fact that GLP-1 drug performance is increasingly understood to include or even depend upon involvement of brain neurochemistry, thus making brain biodistribution vital.

There will be one reference arm using an existing DHT-sema composition and another reference arm using an existing DHT-CBD composition. Lexaria will leverage the wealth of study data that we have amassed from previous work by utilizing our proprietary historical data and the reference arms as baseline comparators to the current Study results as we search for areas of improvement.

The Study is fully funded from existing corporate resources.

Lexaria is also pleased to report that on June 11, 2026 we received our first Australian patent grant (#2023302884) in our Family #21 - Pharmaceutical Compositions and Methods for Treating Hypertension. This patent represents our 7^th patent in this family with 3 others previously granted in the US, 1 in Europe and 2 in Japan. The term of this patent is until April 25, 2043.
