Leading Global Manufacturer Requests HPQ's First Batch of Fumed Silica for Evaluation
MONTREAL, May 28, 2025 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. ('HPQ' or the 'Company') (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company driving innovation in advanced materials and critical process development, is pleased to inform shareholders that the leading global fumed silica manufacturer —under the LOI announced on July 9, 2024 — has requested to receive samples of the material earlier than initially scheduled.
This follows HPQ's May 21, 2025, press release confirming the independent validation [1] of HPQ Silica Polvere Inc.'s (HSPI) [2] fumed silica production using its proprietary Fumed Silica Reactor (FSR) Pilot Plant during the four-batch Phase One test. The request for sample shipment was made before HSPI's technology supplier, PyroGenesis Inc. (TSX: PYR, OTCQX: PYRGF, FRA: 8PY1), completed its planned process and material optimizations in the ongoing testing program. This early interest highlights the growing recognition of the unique potential of HSPI's Fumed Silica Reactor to convert quartz into fumed silica in a single step.

'From the start, one of the goals of the LOI has been to work directly with the world's leading fumed silica manufacturer to validate our FSR's ability to produce material that meets their specifications,' said Bernard Tourillon, President and CEO of HPQ Silicon and HPQ Silica. 'This collaboration gives HSPI access to over 80 years of real-world manufacturing and market expertise—an advantage that accelerates our development and strengthens our commercialization efforts. It's a rare and valuable opportunity.'
Feedback from the leading global fumed silica manufacturer will be instrumental in accelerating the advancement of the pilot plant program, which is focused on two key objectives:
Enhancing product-grade purity to determine market fit better, by:
a. improving process control and parameter stability,
b. achieving higher product surface areas through optimized powder morphology and viscosity.
Reaching the targeted production capacity of 50 tonnes per year (TPY) by:
a. increasing silica conversion efficiency and overall yield
This next phase of collaboration and testing marks a critical step toward commercial validation, positioning HPQ and HSPI to accelerate market entry with a scalable, high-purity fumed silica solution. With direct input from a global industry leader and continued progress on process optimization, HPQ is confident in the potential of its proprietary technology to disrupt traditional fumed silica production and meet growing market demand.

Perplexity AI Reports Explosive Growth as Users Look for Browser Alternatives
Perplexity's AI-powered search engine is growing quickly, with CEO Aravind Srinivas reporting a 20% month-over-month increase and 780 million queries in May, according to TechCrunch. Speaking at the Bloomberg Tech Summit, Srinivas said that the platform could hit 1 billion weekly queries if growth continues. He also argued that internet users are looking for fresh alternatives to legacy browsers like Google's (GOOGL) Chrome, and that integrated search tools in a browser can drive even higher engagement. Confident Investing Starts Here: As a result, the company is preparing to launch Comet, which is a new agentic search engine that can help complete tasks for users. In addition, Srinivas noted on X that Comet will soon include features such as meeting recordings, transcription, and search, although these will not be available in the initial release. Nevertheless, Perplexity is working hard to polish the product, with a release expected in about three to five weeks. It is also worth noting that Perplexity is backed by investors such as Nvidia (NVDA) and Amazon (AMZN) founder Jeff Bezos, and is reportedly closing a funding round that would value it at $14 billion, up from $9 billion in December. Moreover, the search engine recently added a new feature that allows in-chat purchases via PayPal (PYPL) or Venmo. Still, despite Perplexity's growth, Google still dominates the market with about 90% global market share, followed by Microsoft's (MSFT) Bing at around 4%. Which Stock Is the Better Buy? Turning to Wall Street, out of the stocks mentioned above, analysts think that NVDA stock has the most room to run. In fact, NVDA's average price target of $172.36 per share implies more than 21% upside potential. On the other hand, analysts expect the least from MSFT stock, as its average price target of $514.27 equates to a gain of 9.2%. See more NVDA analyst ratings Disclaimer & Disclosure Report an Issue

Construction underway at deeply affordable housing project in Kensington Market
What was once a parking lot in Kensington Market will soon be a four-storey building with deeply affordable homes. Construction of the 78-unit building at 35 Bellevue Avenue is underway. The project is part of the city's rapid housing initiative, which aims to create stable, supportive homes for those in need. "The majority of them will be 350-square-foot studios, so fairly compact, but will have everything you need," said Daniel Ling, a principal at Montgomery Sisam Architects. The common spaces include a communal kitchen, laundry facilities, ample bicycle parking and a private courtyard. "We wanted the residents to feel part of the community," he said. The building integrates wraparound support services, including meal programs, health care, education, and employment resources, making sure residents have the tools they need for long-term housing stability, Ling said. The building will be managed by St. Clare's Housing. "We have a very robust and successful tenant support model," said Andrea Adams, executive director of the organization. "It's one thing to house people but it's another to make sure they remain successfully housed, otherwise you're creating a revolving door of homelessness," she said. "Every time someone experiences homelessness, it's longer and harder, and you want to avoid that." The Kensington Market Community Land Trust says the project is a result of eight years of advocacy for the city to redevelop the underused lot into affordable housing. Ling says sustainability is also a priority. He hopes the mass timber structure — which also incorporates a green roof and solar panel system — serves as a model for future affordable housing builds that balance design and environmental responsibility. "On one hand we have to build a lot and build fast, on the other hand we have to find a sustainable way to build. This project is an example of tackling both issues in innovative ways."

A Little Bad News for Rivian and Lucid
Rivian (NASDAQ: RIVN) and Lucid Motors (NASDAQ: LCID) entered 2025 in different gears. Rivian was entering a year with no major vehicle launch, stagnating deliveries, and a lack of any visible catalysts, while Lucid has strung together six consecutive quarters of record deliveries and is ramping the production of its new Gravity SUV. One thing they both have in common is a growing, albeit more slowly than hoped, electric vehicle (EV) market. Here's the bad news: Some recent data says that the EV market sentiment looks to be souring. Survey says Tesla changed the game when it made EVs "cool" for the first time. Since then, the hype surrounding EVs as the future of transportation has swept the globe, in some countries (like China) faster than in others. But according to a recent survey, that hype could be in decline in the U.S. Where to invest $1,000 right now? Our analyst team just revealed what they believe are the 10 best stocks to buy right now. Continue » Interest in EVs spiraled to its lowest level since 2019, according to a consumer survey commissioned by AAA. Only 16% of respondents reported being "likely" or "very likely" to purchase an EV as their next vehicle, signaling consumer caution. The percentage of respondents who indicated they would be "unlikely" or "very unlikely" to purchase an EV as their next vehicle jumped from 51% to 63%, the highest mark since 2022. The percentage who believe that most cars will be electric within the next decade fell from 40% in 2022 to 23% this year. Not only is interest in EVs down, there's also the lingering pessimism surrounding battery repair costs, total costs, and charging infrastructure -- a story as old as EVs themselves. More specifically, 62% of respondents noted high battery repair costs as a main reason for avoiding going electric, while purchase price was cited by 59% of respondents. The hesitation when it comes to purchase price is understandable. The average transaction price for a new EV in March was $59,205, far higher than the overall average transaction price of $47,462, according to data from Cox Automotive. As far as consumer concerns go, 56% of respondents had the fear of running out of charge while driving, and 55% noted a lack of convenient public charging stations. Pulling support The waning consumer sentiment goes hand in hand with the Trump administration's effort to pull support from the EV industry. House Republicans passed a budget bill on May 22 that will reduce federal incentives for battery manufacturing, as well as other clean energy projects. If the Senate approves it, it would cut the section of the bill that provides the $7,500 EV tax credit. The administration took it a step further, as the bill also institutes a new tax of $250 for EV owners and $100 for hybrid owners. The tax contributes to the Highway Trust Fund to support infrastructure. What it all means Investors would be wise to temper growth expectations for the EV industry this year, especially with tariff uncertainty hanging over the automotive industry. That's especially true considering that first-quarter data could give a different impression. EV registrations grew 16%, according to S&P Global Mobility, and market share rose from 6.9% to 7.7%, year over year. There was a demand pull-ahead effect due to people predicting that the tax credit would soon disappear. Rivian, which is currently waiting anxiously for the R2 launch, lacks momentum in 2025 and could use broader industry strength to boost its stock price. Investors who believe in Rivian long-term should keep their eyes open for a buying opportunity this year. For Lucid investors, while this decline in consumer sentiment isn't ideal, the company has plenty of self-driven momentum thanks to quarters of record deliveries. The company is currently ramping up production and deliveries of the new Gravity SUV EV, which will continue driving total deliveries higher throughout the year. For these two young automakers, the broader industry's health is important. The simple truth is that people aren't taking to EVs in the U.S. as quickly as investors had hoped.
