- United States - / - Pharma - / - NYSE:PRGO Can Perrigo (PRGO) Cut Jobs Yet Sustain Innovation, Expansion and Its Dividend Commitment? - On March 11, 2026, Perrigo Company plc outlined at the UBS Global Consumer and Retail Conference its plans to focus on core businesses, deepen retailer partnerships and cut about 7% of its global workforce to streamline operations amid a soft market backdrop. - An interesting angle for investors is how Perrigo aims to balance these cost reductions with continued investment in innovation, geographic expansion and a maintained dividend policy while signaling 2027 as a key year for accelerating its plans. - We’ll now examine how Perrigo’s planned 7% global workforce reduction may influence the company’s existing investment narrative and risk profile. This technology could replace computers: discover 25 stocks that are working to make quantum computing a reality. Perrigo Investment Narrative Recap To own Perrigo today, you need to believe its consumer health and infant nutrition portfolio can eventually convert category softness and recent losses into steadier cash generation. The March 11 workforce reduction and renewed focus on core businesses appear aimed at protecting margins ahead of management’s flagged 2027 ramp. This does not fundamentally change the near term catalyst, which remains visible progress on restoring profitability, or the key risk of weak demand and intense competition limiting that turnaround. The most relevant recent announcement alongside the UBS conference comments is Perrigo’s February 19 decision to maintain its quarterly dividend at US$0.29 per share. In the context of ongoing net losses and a guided sales decline in 2026, continuing the dividend underscores management’s confidence in future cash flows, but also heightens the risk if earnings do not improve, since dividend commitments can compete with reinvestment and restructuring needs at a time when the business is

In brief - Anthropic has filed with the FEC to create an employee-funded political action committee called AnthroPAC. - The move follows a dispute with the Trump administration over military use of the Claude AI model. - The filing shows how AI companies are preparing to engage more directly in U.S. politics. Artificial intelligence giant Anthropic has filed paperwork with the Federal Election Commission to create a political action committee, signaling a deeper move into U.S. politics as the fight over AI policy and its own ongoing battle with the White House intensifies. The San Francisco-based company registered the Anthropic PBC Political Action Committee, known as AnthroPAC, in a filing on Friday. The committee is structured as a separate segregated fund tied to the company, and authorized to make political donations funded by employee contributions. According to a report by Bloomberg, those contributions are capped at $5,000 per employee. Employee-funded political action committees (PACs) allow companies to collect voluntary contributions from employees and distribute those funds to candidates and political committees. Other tech companies that have established political PACs include Google, Microsoft, and Amazon. In 2024, those three PACs alone contributed more than $2.3 million to U.S. political candidates, according to campaign finance data by the nonprofit research group OpenSecrets. While contributions went to both Republicans and Democrats, donations skewed toward GOP candidates during the 2024 campaign season. Anthropic’s move comes during an escalating conflict with President Donald Trump’s administration over the military use of its AI systems. In February, Trump ordered federal agencies to stop using Anthropic’s technology following a dispute between the company and the Pentagon over how the military could deploy its Claude AI model. Despite an ultimatum by the U.S. Department of Defense, Anthropic refused Pentagon demands to remove safeguards that prohibit the system from being

Google’s whitepaper warns that quantum computers may break current cryptography by 2029. Computer scientist Guy Zyskind says post‑quantum cryptography—particularly lattice‑based schemes and encrypted mempools—is essential to secure blockchains. The Retroactive Decryption Trap: Why Post-Quantum Upgrades Can’t Save Your Past Privacy Reframing the 10-Year Migration Window The recently released Google whitepaper on the quantum threat has ignited intense debate over the technical justifications that led authors to aggressively pull forward the migration deadline to 2029. While a few critics have dismissed the findings as alarmist, a broad consensus of industry experts suggests that a warning of this magnitude from a primary driver of quantum research should serve as a definitive wake-up call for developers to begin immediate post-quantum preparations. Guy Zyskind, computer scientist and founder of Fhenix—a project integrating fully homomorphic encryption (FHE) into the Ethereum ecosystem—noted that the whitepaper effectively reframes the conversation. According to Zyskind, the traditional 10-year migration window, which until recently felt pessimistic, now appears “dangerously optimistic” in light of Google’s findings. Perhaps the most significant takeaway is the weight of the messenger itself; the fact that a tech titan of Google’s stature has attached its name to such a specific timeline should prod the blockchain community toward a fundamental architectural shift. Regarding why the findings in the whitepaper have gained traction, Zyskind said: “Previous papers in this space tended to be either too theoretical or too optimistic about qubit requirements. This one feels like it’s closing the gap in a way that should make people uncomfortable.” Meanwhile, the Google whitepaper’s core revelation has sent shockwaves through the blockchain community: Researchers have demonstrated that a “cryptographically relevant quantum computer” (CRQC) could achieve a 41% success rate in hijacking a transaction before it is even confirmed. Critics warn that this vulnerability could transform the mempool into a “shopping

Solana begins testing defenses against 'quantum-computing threat'… "Stronger security leads to slower performance" Summary - Solana (SOL) is reported to be conducting tests to apply post-quantum cryptography in cooperation with Project Eleven. - The tests confirmed the potential for stronger security, but also resulted in performance degradation, with data sizes increasing by 20–40 times and speeds slowing by about 90%. - CoinDesk reported that this clashes with Solana’s structure, which emphasizes fast processing, and assessed that it creates a dilemma between security and performance degradation. Forecast Trend Report by Period As Solana (SOL) begins testing security technologies to prepare for the era of quantum computers, early results reportedly confirmed a clear trade-off between tighter security and slower performance. According to CoinDesk, a cryptocurrency-focused outlet, on the 4th (Korea time) the Solana Foundation is conducting experiments to apply "post-quantum cryptography" in cooperation with the cryptography firm Project Eleven. Post-quantum cryptography is designed to prepare for the possibility that future quantum computers could break existing cryptographic systems. In fact, the industry has raised concerns that if quantum computers are realized, they could threaten the security of today’s blockchains. Test results suggest the chances of improving security are promising, but performance degradation emerged as security is strengthened. Specifically, post-quantum-resistant signature schemes were found to increase data size by 20–40 times compared with existing methods, while speeds fell by about 90%. CoinDesk assessed that "this conflicts with Solana’s architecture, which touts fast processing speeds as a key strength," adding that "the more security is strengthened, the more it creates a dilemma with performance degradation."

In brief - Algorand surged more than 40% over the past week after Google cited its "real-world deployment" of post-quantum protocols in a research paper. - Render gained almost 10% in 24 hours, driven by AI demand and adjacency to the trend. - Myriad users see an 82% chance that oil hits $120 next, as geopolitical uncertainty persists. Algorand has extended its rally over the past week, supported by a recent citation in a Google research paper singling out the blockchain as an early adopter of post-quantum protocols. Algorand jumped around 13% in the past 24 hours to $0.12, according to CoinGecko data, far outpacing the broader crypto market. It is up over 44% in the past week, a move experts attribute to growing interest in the quantum-resistant narrative. Google's whitepaper, "Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities," published on March 31, identified Algorand as an example of "real-world deployment of PQC on an otherwise quantum-vulnerable blockchain." The paper highlighted that Algorand had deployed post-quantum Falcon digital signatures for smart transactions and state proofs, executing its first PQC-secured transaction in 2025, and enabling native key rotation. “While this mechanism does not provide full quantum security at present, it facilitates future PQC migration,” the paper’s authors wrote. The rally reflects “renewed focus on quantum computing risks” following the publication of Google’s paper, Leo Fan, founder of Cysic and former lead on quantum resilience at Algorand, told Decrypt. “Algorand stands out because it has post-quantum signature schemes like Falcon live on the mainnet and was specifically referenced in the paper, giving it strong technical and narrative momentum,” he said. If the discussion around quantum security continues to gain traction, Fan added, it could “evolve into a durable market theme” grounded in credible long-term risk and institutional research support. Other analysts echoed Fan’s

Five Ways Quantum Technology Could Shape Everyday Life With billions invested and prototypes being tested outside the lab, the quantum era is starting to take shape. Image Credit IBM Share The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop “the world’s most powerful commercial quantum computer” mark just two of the latest developments in quantum technology’s increasingly rapid transition from experimental breakthroughs to practical applications. There is growing promise of quantum technology’s ability to solve problems that today’s systems struggle to overcome or cannot even begin to tackle, with implications for industry, national security, and everyday life. So, what exactly is quantum technology? At its core, it harnesses the counterintuitive laws of quantum mechanics, the branch of physics describing how matter and energy behave at the smallest scales. In this strange realm, particles can exist in several states simultaneously (superposition) and can remain connected across vast distances (entanglement). Once the stuff of abstract theory, these effects are now being engineered into innovative, cutting-edge systems: computers that process information in entirely new ways, sensors that measure the world with unprecedented precision, and communication networks that are virtually impossible to compromise. To understand how this emerging field could shape the future, here are five areas where quantum technology may soon have a tangible impact. 1. Discovery for Medicine and Materials Science A pharmaceutical scientist seeks to design a new medicine for a previously incurable disease. There are thousands of possible molecules, many ways they might interact inside the body, and uncertainty about which will work. In another lab, materials researchers explore thousands of different atomic combinations and ratios to develop better batteries, chemicals, and alloys to reduce transport emissions. Traditional supercomputers can narrow the options but eventually meet their limits. This is where quantum computing could make

Further Than Anyone Has Gone Before We’re on the cusp of the most extraordinary productivity boom in the history of the world. The entire internet will need to be upgraded to post-quantum encryption technologies. Managing Editor’s Note: Earlier this week, Jeff discussed in the issue Blockchains to Be Hacked by Quantum Computers the risk that rapid quantum computing developments pose to blockchain technology and, by extension, cryptocurrencies. But digital assets aren’t the only ones at risk… Quantum computing represents an unprecedented threat to the encryption systems that safeguard nearly all digital information and infrastructure today. As markets are closed today, we’re taking this opportunity to spotlight an issue where Jeff emphasizes the importance of equipping existing and future IT infrastructure with post-quantum encryption measures. There’s a quantum threat that’s building as quantum technology grows more advanced… The incredible developments of the last year or so in quantum computing – specifically the breakthroughs in quantum error correction – are signaling a once-in-a-generation shift in information technology (IT) infrastructure. The reality is daunting. The entire internet will need to be upgraded to post-quantum encryption technologies. Every piece of IT infrastructure will require post-quantum encryption software and hardware (semiconductors) to protect against quantum computers. This includes necessary upgrades for all communications systems and the current gold standard encryption technology. None of it will protect against the threat of quantum computing technology. Any stored file will also need to be re-encrypted using post-quantum encryption standards. Otherwise, files can be easily decrypted using quantum computers. Today, those knowledgeable in the industry about the latest advancements in quantum computing technology are already beginning this process of upgrading their IT systems. It’s still early, but those companies and government entities that are most sensitive to the threat of quantum computing systems are taking action now. The rest

Thomas Huffstutler and colleagues at the Stony Brook University have identified the conditions under which quantum computers cannot outperform classical algorithms. Their work presents a key framework for definitively excluding the possibility of quantum speedups. The team utilise promise-aware complexity measures and function completions to determine when superpolynomial quantum speedups are unattainable for partial Boolean functions. This connection between the collapse of specific complexity measures and polynomially related deterministic and quantum query complexities offers sharp characterisations for structured function families. By formalising completion complexity, the study further identifies criteria for ruling out speedups in functions with predictable properties, advancing understanding of the limits of quantum computation. Defining computational limits using minimal function extension Completion complexity, a central technique in this analysis, operates much like filling in gaps in an incomplete puzzle to reveal the full picture. It is formally defined as the minimum complexity needed when extending a partial function, one defined for only some inputs, into a total function applicable to all inputs. This process of ‘completion’ isn’t arbitrary; it seeks the simplest total function consistent with the known values of the partial one, effectively minimising computational effort. Establishing criteria for when a quantum speedup is impossible is now possible through analysing how complexity measures change during this completion process, revealing fundamental limits to quantum computation. The approach was employed to determine when quantum computers can outperform classical algorithms, focusing on partial Boolean functions. Using a ‘gap parameter’ to characterise potential speedups, the analysis focused on symmetric functions and those defined on ‘slices’ of the input space. The minimum complexity of all possible total functions extending the partial one proved important in identifying limits to quantum computation and establishing criteria for when a quantum advantage is impossible. Polynomial relationships between deterministic and quantum query complexity for partial Boolean A

Key Points Quantum computing stocks D-Wave and Rigetti have seen double-digit drops year to date. Both D-Wave and Rigetti are not profitable but have amassed large cash hoards on their balance sheets. D-Wave is growing bookings, while Rigetti captured a big customer order in 2026. Quantum computing has the potential to transform technologies such as artificial intelligence (AI). It can process complex data in minutes that would take centuries for a conventional computer. The sector sparked strong investor interest in 2025, but the "great rotation" of 2026 changed the situation. Wall Street shifted away from tech stocks with sky-high valuations this year, which includes the nascent quantum computing industry. Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an "Indispensable Monopoly" providing the critical technology Nvidia and Intel both need.
